DESCRIPTION
NOTICE TECHNIQUE SBO 6 - ANGLAIS
-1-
I - GENERAL PRESENTATION
To manufacture bi-oriented PET bottles intended for the preservation of flat and carbonated
drinks, SIDEL has chosen the cold process.
This process implies:
Heating the preforms.
Mechanical axial stretching, subsequent radial stretching by blowing in compressed
air.
This process optimizes production and excellent flexibility of operation and use.
1-
DEFINITION
The SBO 6 is designed to manufacture PET bottles. Its rate can reach up to 7.200
bottles per hour according to the bottle capacity.

II - GENERAL PRESENTATION
The bioriented PET blow machine SBO 6 can be divised into the following main functions,
knowing that movements are controlled by cams and cam follwers.
1-
COLD PREFORM INFEED
SBO 6 can be provided with a storage and loading system placing preforms on the
machine entry rails.
Cold preforms are inserted by an inclined ramp. They hang by the neck and are
guided by two rails between which they are lowered by gravity.
The ramp lower ends is linked to the loading wheel of the preform reheating linear
oven. This loading wheel transfers preforms with a defined step to the 30-notch wheel
and and then to the infra-red oven spindle chain.
2-
PREFORM REHEATING LINEAR OVEN
The preforms, grasped in the spindles at the neck are made to rotate as they pass in
front of infrared lamps.
A preform ejection system operates automatically in the event of incorrect coating or
defective preforms. It is placed before the swivel point of the spindle.
A shaped section is kept cold by air circulation to protect the neck of the preforms from
infrared radiation.
A ventilation system is used to cool down the neck of the preforms when they pass at
the end of the oven.
The linear oven has 10 heating modules. Each oven module includes 10 infrared
lamps.
At the oven exit, an infrared camera reads the preform temperature. This information
provides automatic regulation of all the areas coming under its control.
3-
HOT PREFORM TRANSFER WHEEL
A transfer wheel with 3 arms conveys the hot preforms through the blowing moulds
when they leave the oven. Each arm has a gripper made of two hinged fingers which
grasp the preform at the bottom of the neck, below the collar when the preform is
released by the spindle. The preform held in this way is transferred by the rotation of
the arm into the blowing mould.
4-
PREFORM EJECTION
An ejection system is mounted after the preform transfer wheel. It is possible to
manually eject preforms before they are introduced into the mould, in the case of a
non correct temperature, after a long stoppage for example.
-3-
5-
BLOW WHEEL
The preform is put into the mould for which opening and closing are assured by a
system of connecting rods operated by a cam.
The mould is locked by a mechanical device.
The blow nozzle nose is put into the neck of the preform. Tightness for the blown-in
air is by an O-ring bearing against the preform lip.
The blow nozzle guides the stretching rod which ensures longitudinal orientation.
Blowing which ensures a lateral orientation is in two stages so that the wall thickness
is evenly distributed.
- Pre-blowing at medium pressure.
- Blowing at high pressure.
A set of cams synchronizes the process.
The moulds are controlled for temperature by water circulation.
This set of equipment provides optimum reliability and quality for production.
6-
BOTTLE TRANSFER WHEEL
A transfer wheel with 3 arms picks up the bottles in the moulds in order to evacuate
them from the blowing wheel. This system is identical to the preform transfer wheel.
7-
BOTTLE EJECTION
An ejection system is mounted after the botle transfer wheel. This system is identical
to that of preform ejection. It is completed by a set of photocells which in automatic
mode controls the width of bases and shoulders. If the bottle is not correct, it is ejected
instead of progressing to the bottle outfeed device.
In the Manual mode, the bottles can be ejected before the bottle output device.
8-
BOTTLE OUTFEED WHEEL
An outfeed wheel with 6 notches receives the bottles brought by the transfer arms and
puts them down on a belt. They are held by guides. The bottle outfeed can be linked
to a conveyor system.
-4-
9-
ELECTRICAL CABINET
The electrical cabinet contains the power and control equipment.
A programmable logic controller ensures the operation of the machine and supplies
elements to assist with production management.
10 - CONTROL CONSOLE (P.C.) - CONTROL/MONITORING STATION (P.C.C.)
10 - 1 Control console
The control console groups together the control and monitoring items required
to operate the machine.
An alphanumeric display is used to monitor the machine whose operation is
fully automatic. It facilitates diagnosis when the machine is stopped upon
safety requirement.

The machine is equipped with a NEMATRON tactile industrial PC, connected
to a 115U SIEMENS programmable controller located in the cabinet. Its
purpose is to control and monitor the machine.
This control/monitoring station is called P.C.C.
Operating mode:
The machine is provided with 3 operating modes:
* ADJUSTMENT MODE: Used to adjust the machine.
* MANUAL MODE:
Used to configure the process (the operations
take place at the request of the operator).
* AUTOMATIC MODE: Used to set up production. The machine startup operation automatically engages the whole
production cycle without the operator's
intervention.
11- MACHINE PROTECTION
A great number of safety devices are used to avoid mechanical damage:
* Either in a preventive way (ejection of incorrect preforms before thermal treatment,
ejection of preforms not blown or badly blown, etc.).
* Or via a very fast machine shutdown (abnormal efforts, etc.).
After safety stop, automatic machine draining takes place at reduced speed, before
restarting production.
Emergency stop pushbuttons placed around the machine enable the operator to stop
in case of incident.

III - KINEMATIC CHAIN
1-
DESCRIPTION
In the diagram of showing the kinematic chain, the following assemblies can be
recognized:
- The reduction motor gearbox.
- The manual rotation device.
- The drive crown of the blowing wheel.
- The slotted wheel feeding the infrared oven (30 slots).
- The 3-arm preform transfer wheel.
- The 3-arm bottle transfer wheel.
- The 6-slot bottle output wheel.
The motor-reducer output transmits power in 2 directions:
* The blowing wheel via a 25-tooth gear meshing with the 125-tooth crown
gear.
* To an intermediate shaft via a pulley and timing belt transmission
system. From the latter, the movement is transmitted to the infrared oven
and the preform transfer.
The rotation of the infrared oven is provided by an epicyclic
module. It reverses the direction of rotation and demultiplies the
speed in a ratio of exactly 10.5.
* From the bottle transfer wheel, the movement is transmitted to the bottle
transfer then to the bottle exit wheel. ItÕs rotation is reversed by a gear
train.

MOTORISATION
It is an asynchronous motor-reducer with a power of 4 kW. The output speed is 94
revolutions per minute for a production of 7.200 bottles per hour.
A torsion-rigid chain coupling caters for shaft alignment faults and any offset in an
axis.
The bearing and motor-reducer are not affected by the additional forces caused
inevitabily with rigid coupling.
3-
MANUAL ROTATION
The manual rotation device enables the machine to be rotated so that, for example, it
can be adjusted.
Before rotating the machine, the technician must check that nobody
is standing behind the sides of the machine which cannot be seen
from this device.
It is necessary to release the brake mechanically (see page 90).
!
4-
BELTS
The motion is transmitted to the various units by notched belts. These are reinforced
with metal cables and hardly elongate thus making transfer motion (meeting points)
very precise.
However, too much tension will damage the belts, shafts and their bearings.
This is why each machine is supplied with a device to check the tension, and a
calibrating tool (see page 109).
5-
BRAKES
A electromagnetic brake is fitted onto a shaft in gear with the blow wheel ring. It stops
the machine rapidly when a safety device trips.
During stoppage due to a safety device, braking is instantaneous.
During normal stoppage, braking is time-delayed.
When the brake is applied and no power is supplied, it can be released using a
manual device.

TORQUE LIMITERS
6 torque limiters protect:
- The motor-reducer.
- The preform transfer wheel.
- The bottle transfer wheel.
- The bottle exit wheel .
- The infrared oven.
- Preform feeding wheel.
These devices enable uncoupling in the event of overload.
The electrical safety device, actuated by the movement of part of the limiter, controls
motor stoppage and assistance for the brakes.
The torque limiters are calibrated in the plant. This adjustment must never be
modified.
The adjustment values are as follows:
* Motor-reducer torque limiter ..................................................................... 60 mdaN
* Preform transfer wheel torque limiter ....................................................... 17 mdaN
* Bottle transfer wheel torque limiter............................................................ 17 mdaN
* Bottle exit wheel torque limiter ................................................................ 2,0 mdaN
* Infrared oven torque limiter ...................................................................... 17 mdaN
* Preform feeding wheel torque limiter ...................................................... 3,0 mdaN

DESCRIPTION
The purpose of the infrared oven is to bring the preforms to a temperature included
between 105 and 120¡C before they are drawn-blown in the finishing wheel.

HEATING OF PREFORMS
10 modules placed either side of the oven are needed to heat the preforms. Each of
them can be equipped with 10 infrared lamps.
* The lamp power can be 1 or 2 kW.
The number and power of the lamps depends upon the type of preform to
be heated and on the article to be produced.
The lamps are mounted on two frames either side of the oven.
The frames allow the lamp assembly to be moved in height or in depth.
The lamps are spaced at intervals of 22 mm and held in the same plane by
their ends in a slotted box.
A sliding cover protects the ends of the lamps from infrared radiation.
The operation of the infrared lamps means that the ends have to maintained at a
temperature of less than 250¡C.
A fan mounted at the back of the oven flows the air through the longitudinal members
of the chassis. Each oven module is ventilated by a tap to provide efficient cooling of
the lamp ends.
Opposite the lamps, reflectors retransmit part of the infrared rays to improve the oven
heating capacity.
Two other fans maintain the temperature of the oven at an acceptable level for
mechanical parts and in particular for the conditioning of the preforms.
On each fan, there is a trap for adjusting the flow.
A water circulating ramp ensures the protection of the nets by forming a shield against
infrared rays.
The ramps can be adjusted by holes in their support. To be efficient, they should be
as close as possible beneath the collar.
It must be noticed that when a complete module is not justified, the oven can be
equipped with additional pairs of lamps at the end of the oven. This particular
assembly is called "angle oven".

REGULATION
Module n¡ 1 is the model in which the preforms entering the oven penetrates.
Depending upon the path of the preforms, the following modules are encountered in
order:
1 - 2 - 3 - 4 - 5 - 6 - 7 - 8 - 9 and 10
The modules can be equipped with up to 10 lamps.
Adding lamps of the same row makes up a heating zone.
The oven assembly consists of 10 zones corresponding to 10 rows of lamps for
ovens 1 to 10.
Each heating zone is controlled by a regulator.
The modules 1 and 2 are non-regulated, they operate at their 100 % capacity.
A thermocouple in module No. 5 is used to check oven internal temperature.
The thermocouple measurement is displayed by the PCC.
An infrared camera is aimed at the preforms when they exit the oven:
The camera is connected to the PLC, which transmits the temperature to the
PCC. The preform temperature is then displayed on the PCC. The PLC controls
and corrects the heating applied in each zone according to the established
heating profiles.
4-
PREFORM INFEED
The cold preforms are put into the machine on an inclined ramp.
They are suspended by their necks and guided by two inclined rails between
which they are lowered by gravity.
The ramp lower end is in contact with the feeding wheel, which allows preform
introduction into feeding plate notches.
A finger activated by a pneumatic cylinder makes it possible to stop feeding by
stopping preforms before the feeding wheel.
Stopping can be manual from the control panel or automatically after a fault is
generated.
A retractable guide installed on a pneumatic cylinder is used as a
preform feed safety device. In case of defective preform feed, the
guide displacement is detected and its cylinder is used to retract it
fully home. (See PCC manual).
A couple limiter installed at the end of the preform loading wheel shaft is used to shut
down the machine in case of abnormal effort.

SLOTTED INFEED WHEEL
This is a wheel with 30 slots in which spindles mesh with each other. It is integral with
the transmission and drives the spindle chain assembly.
The preforms placed in the feeding wheel are loaded onto the plate on the wheel. In
this way, the preforms turn in step with the spindles.
A fixed cam works on a fork to load and unload the preforms.
The forks are guided on the infeed wheel by bronze bushes which mesh with the
spindles.
* During the infeed, the spindle is held in the high position. There is a clearance
of up to 5 mm between the lip of the preform and the nose of the spindle.
* The preform engages into the slot of the infeed plate while a countercamcauses the insertion of an elastic bush in the neck (loading). There must
be a clearance of 0.2 to 0.3 mm between the fork and the spindle-bearing
washer.
This cam, held by a spring can retract. Any considerable force on the spindle nose will
cause it to move and arm a contact.
After loading and to check the preforms, the fork lifts away from the infeed plate
slightly.
The fork disengages from the spindles.
* Conversely, the position of the cam must permit the engaging of the fork with
some clearance between pinion and spindle-bearing washer.
The unloading of the preform takes place just before transfer, when the fork rises.

DETECTION - EJECTION OF PREFORMS
Immediately after loading, the preform lifts off the infeed plate slightly.
A motorized disc drives the spindle in rotation by friction.
* This is a way of checking the preform.
The purpose is to evacuate any deformed or badly loaded preforms which could
interfere with the operation of the oven.
The preform spins rapidly as it passes through the center of a "tuning fork".
All the preforms causing the tuning fork to move are ejected.
* A flag drops over a cell controlling the ejection actuator.
* The ejection actuator causes the uncoating of the preform by pushing the fork
upward.
* A compressed air bellows ejects the preform into a chute.

SPINDLES
There are 120 spindles which are designed to:
* Pick up the preforms in the infeed wheel.
After their insertion on the slotted plate, the flexible bush mounted at the
shaft end enters the neck of the preform.
The tightening of this bush is sufficient to hold the preform throughout its
passage through the oven.
* To ensure the turning over of the preforms.
* To ensure the running of the preforms in front of the heating modules.
* To put the preforms into rotation so as to distribute the heating regularly and
consistently.
They are assembled with one another and form a chain with a constant pitch of
60.3 mm.
Assembly is by swivels to permit the pivoting of the preforms and the passage
of the spindles in the slotted wheels.
The rear wheel of the oven is a tensioning device. The tension of the spindle chain is
obtained by pneumatic cylinder. The pressure on this cylinder creates a constant force
by which the two lengths can be kept under tension.
The spindle mainly consists of a body including:
- On one side a spherical concave bearing.
- On the other side, a pin and a key which support the spherical convex
bearing forming thus with the next spindle, a joint.
- On either side of the body, the covers which support the cylinders.
Each cylinder is equipped with a bronze ring in which the main pin will
rotate thanks to a pinion, but will also slide during preform removal and
loading operations.
A spring ensures the rest position.
At the end of the pin is fitted the personalization part provided with a snap
ring which holds the preforms.
- Two rollers fixed on either side of the spindle body ensure the guiding in rails
all along the oven.
These rollers in grooves which ensure the turning over of spindles and hold
them in place. All guiding and turning over cams of spindles is factory
mounted and adjusted and must not be altered.
After preforms turn over, this pinion engages into a chain.
IMPORTANT: Comply with spindle greasing procedure, page 124.

MOULD OPENING/CLOSING CONTROL
The moulds are opened and closed by a roller in gear in a cam.
Motion is transmitted as follows:
From the roller fitted on a toothed part of a pinion in order to amplify the motion
(ratio 2).
From the pinion to a pin through the 2 plates of the mobile wheel.
From the pin to a connecting rod via the square end piece of the pin.
From this rod to 2 others fixed on the back of the brackets, so that the mould
opens symmetrically.
The toothed part is installed on its shaft via a cone ring. It is used to adjust the mould
opening/closing device.
When there is a mechanical incident, it also allows the parts to slide against one
another.

BASE MOULD
For the production of articles with auto-stable bases, the mould does not include two
but rather three parts. Only one retracting part will allow the mould release for this type
of base.
The third part is mounted on the lower plate of the mobile wheel.
It consists of:
- 1 rod:
The rod slides between two ball collets mounted in the bracket.
- 1 base mould support:
The support is mounted at the upper end of the rod. Two spot faced holes
machined into the bottom support receive O-rings to provide tightness for the
cooling water system.
- 1 base mould raised section:
This intermediate part is customized according to the mould heights.
- 1 roller support yoke:
This yoke is mounted at the lower end of the rod and permits the assembly lifting
and lowering movements.
The yoke abuts on the shoulder of the rod by means of a peel-off shim washer
in order to permit fine adjustment of the base mould height with respect to the
mould itself.
- 1 guide:
The guide is attached to the yoke and prevents the assembly from turning. It has
a spring preventing the roller from moving off the cam during descent of the base
mould thus eliminating shock on contact with the roller.
- 1 shock absorber:
The shock absorber absorbs shock during the descent of the mold bottom.
There are 2 cams to ensure:
- The lowering of the base once the mold has opened.
The cam for the base mould descent is retracting. A safety contact detects
the assembly when is reaches the low level. An actuator then clears the
cam. In this way the mould assembly can be protected. Indeed, the
inadvertent rising of the base mould after descent could damage the lower
part of the two half-moulds.
- The lifting of the base before the closing of the mould.
The base mould lifting cam is mounted on springs. Any abnormal force will
move this cam to arm a contact and cause the machine to stop instantly.

BLOW NOZZLE CYLINDER
The blow nozzle cylinder assembly is a pneumatic device by which the blow nozzle
can be applied to the rim of the preform and put under pressure in order to form the
bottle.
The stretching rod passes through the assembly.
There are 2 different functions:
- The control part.
- The blowing part.
* Both of them consist of hollow rods.
At the end of the hollow rid, the nozzle assembly is screwed on, customized to the
preform being used.
Theory of operation:
- The pressure establishes between the rear base and the hollow rod causing
the blow nozzle to descend.
When there are no preforms, the end of travel is dampened by the o-ring
mounted on the hollow rod.
- The stretching rod descends in order to draw out the preform.
It is guided by the rear base in which the bronze bush is mounted and at
the end of which there is a hollow stem consisting of a brass socket
(diffuser).
- The pre-blow and blow pressures are established on the cylinder HP body.
- The HP circuit communicates with the bottle through the HP body. The hollow
shaft, drilled through, allows air to circulate along the stretching rod.
* The diffuser is a square section part allowing air to pass.
* The tightness of the blow nozzle on the neck edge is obtained by an Oring.
* A lip seal mounted on the hollow rod isolates the low pressure controller
from the high pressure air.
* The air in communication HP body, working on a piston fitted to the
threading to the hollow rod, establishes a back pressure which maintains
the blow nozzle in contact with the neck edge.
* Tightness is thus assured on the rim whatever the pre-blow and blow
pressure.
- When the pre-blow - blow cycle is over, with the bottle on the exhaust, the
pressure established at the front of the base by working on the hollow shaft
works back of the blow nozzle.

STRETCHING
The purpose of the stretching is to mechanically elongate the preforms once
they have been run through the oven.
The assembly breaks down as follows:
- A pneumatic cylinder supplies the energy needed for stretching.
- A slide is guided by two columns.
- A stretching rod on the slide is attached by a tightening yoke.
- A roller in contact with a cam during stretching allows regulation of the
stretching speed.
The stretching rod is guided in the blow nozzle. It enters the preform and draws it out.

THREE-WAY VALVE
The purpose of the 3-way valve is to switch the pre-blow and blow pressures
and to make sure that bottle gas relief operates.
Description:
Essentially the 3-way valve consist of:
* A body.
* A piston.
* A lever with bearings.
Theory of operation:
On the passage of the preblowing then blowing cams, the lever is operated to
control the movement of the piston and determines the functions:

RECOMMENDATIONS
Compressed air system:
Operation and maintenance of compressors and of their engines and fittings
must comply with the manufacturerÕs instructions and specifications.
The compressor lubricant must meet the specifications.
The compressor or the inlet of its suction piping, when there is a separate inlet,
must be in a clean area, i.e. in an area with the lowest possible contamination
from engine or process gas exhaust.
Contaminants:
- Solids:
Dust is always sucked into the compressor with the air, although most of it
is stopped by the suction filter.
When air circulates in the compressor and its piping, bigger particles (rust,
worn-off particles, etc ...) may accumulate, be suspended in the oil and
removed by the oil filters.
If the piping is in good condition, rust and metal particle concentration is
usually between 2 and 4 mg/m3, but concentration peaks may occur when
the air flow is started up again or after mechanical shocks on the pipes.
- Oil (mineral or synthetic):
In compressors with a lubricated compression chamber, the air is bound to
collect some oil. The air from non-lubricated (dry) compressors may also
contain traces of oil which could have been sucked with the air.
A non-toxic lubricant is sometimes used for some applications.
Oil in compressed air may have the following states:
* Liquid.
* Aerosol.
* Fumes.
Only a small amount of the oil fed into the compression chamber of a
positive-displacement compressor remains in the air compressed. Most of
it is drained with the condensate from the inter- and final stage coolers. The
possibility of filtering out the oil carried into the compressed air depends on
the type of compressor as well as on the type of oil, and also on the stress
met by the oil inside the compressor. All these factors influence the size
and the composition of the oil particles.

HIGH PRESSURE SYSTEM
3-1
Pneumatic board
Fitted on the rear side of the machine, it includes all the air treatment section :
* A time-delayed electrovalve, fitted at the head of the system, cuts the
machine off from the factory mains.
!
It must be closed for any servicing on the machine.
* A valve rated at 50 Bars prevents any overload on pneumatic
elements and protects them against overpressures.
* A filter purifies the air in case of factory mains failure, it removes solid
and liquid particles having a diameter of up to one micron.
The most important part of the filter is the filtering element.
* It allows solid or liquid particles to be removed by means of
microfibres.
* Solid particles are permanently caught.
* Liquid particles progressively form bigger and bigger drops which fall
to the bottom of the filter tank.
Automatic draining removes the waste accumulated in the bottom of
the filter tank.
The service life of filtering cartridges is estimated to be one year.
- Solid particles actually end up clogging the filtering cartridge,
resulting in the increase of the loss of pressur of the filter.
A periodical check of the clogging indicator is provided, so that
the filtering cartridge can be replaced when the red indicator
appears.
* A high pressure reducer.
It reduces the upstream pressure to a lower downstream pressure,
with regulated pressure and flow.
* The reducer is operated by means of a throttle. The position of this
throttle controls the opening of a check valve to keep downstream
pressure constant. The throttle is provided with air pressure
trapped in the dome cavity.
* Any reduced downstream pressure can be obtained by admitting
air coming from upstream to the pressure used in the dome by
means of needle screws.
- 34 -
PNEUMATIC TABLE
- 35 -
* A second valve calibrated at 40 Bars again protects the equipment
from an overpressure due, for instance, to the malfunctioning of a
regulator.
* A 3-way valve, with pneumatic control by a membrane, establishes
the pressure on the blowing wheel.
- When a door is opened, or after a shut-down, this valve
connects all the blowing stations to the exhaust.
- The valve is controlled pneumatically. The control air is drawn off
a tap in the high pressure circuit. The air is relieved at a pressure
of less than 10 Bars. This circuit is protected by a valve
calibrated at 10 Bars.
- A pressure switch mounted between the regulator and the valve
detects any lack of air and controls a gradual machine shutdown procedure.

Air inlet central part
The air inlet central part is located in the lower part of the mobile blowing
wheel and connected to the pneumatic panel to supply of the 6 blowing units.
It consist of:
* 1 rotary union.
* 1 rotating joint.
* 1 air distributor.
- Rotary union:
This assembly is manufactured to supply the blowing wheel air at
40 Bars. It is mounted on the rotating joint which provides connection
with the piping carried on the machine.
- Rotating joint:
Mounted on the air distributor, the rotating joint is used for
* A passage for air at 40 Bars to air distributor.
* A inlet of 7 Bars lubricated air.
- Air distributor:
The air distributor ensures the distribution of:
* Blowing air fit directly by the high pressure air system.
* Pre-blowing air obtained from the high pressure air relieved by
a pressure regulator.
Each of the blowing and pre-blowing air taps is connected to the 3way valve manifold block of the blowing units.
On each blowing and pre-blowiong circuit there is a flow limiter
which regulates the air flow so as to combine the effects of blowing
and stretching.

LOW PRESSURE SYSTEM
The low pressure system is used to control the following cylinders:
- The strechings cylinder.
- The blow and pre-blow retracting cam cylinder.
- The base mould cam cylinder.
- The preform and bottle ejection cylinder.
- The preform infeed cylinder.
- The ejection cylinder of the faulty or badly loaded preforms.
- The oven thightener cylinder.
These cylinders are controlled by distributors in different parts of the machine.
The stretching operation requires a circuit installed on the mobile wheel,
supplied with air from the rotary union of the air inlet central part.
The low pressure system air is processed on the pneumatic board.
!
A valve at the head of the system cuts the machine off from the
factory air system.
The pneumatic panel includes:
* A filter - pressure regulator with a manometer - lubricator set which
processes the factory system air.
- The filter eliminates water, which condenses by cooling in pipes, and
solid particles such as rust for instance.
It is equipped with a drain which can be:
- Manual: You need only unscrew the plug a little and let the residue
escape. Once the tank is empty, screw the plug back on.
- Automatic (with no pressure): When the plug is removed, a spring
opens the draining device when there is a pressure lower than
0.2 Bars and shuts it off when the pressure is higher than 0.8 Bars.
The filter tank is fixed by means of a bayonet device. It is highly
recommended to clean the tank and cartridge periodically. They
must be cleaned using oil or an alkaline solution, but not using any
chlorinated or alcoholized product.
- The pressure regulator keeps upstream pressure constant
whatever the pressure variations in the factory mains may be.
- The lubricator adds a lubricant compatible with the correct
operation of the pneumatic components to the air. The oil flow can
be adjusted by a needle screw and checked through an aperture.
The average oil/air ratio is 3 to 5 drops/Nm3 air.
- 39 -
* A 3 way valve provides the exhaust for the entire circuit as soon as the
machine stops.
NOTE
The air supply unit of the infrared oven tightener is
equipped with a check valve and a bleeding valve.
For any intervention on the spindle chain or on the
tightener, it is compulsory to bleed this system.

VII - WATER CIRCUIT
1-
DESCRIPTION
The water system assembly breaks down into the following:
* A hydraulic panel for connecting the machine to the water treatment
installation.
* A hot water rotary union (option).
* A cold water rotating joint.
* A set of pipes carried by the machine feeding the moulds and the base
moulds.
* A inlet circuit for the cooling ramps and which protect the necks of the
preforms in the infrared oven.
Basically there are two different circuits:
Standard:
* The simple cold water circuit for moulds, necks and base moulds.
On option:
* The double circuit:
- Cold water circuit for cooling the necks and base moulds.
- Hot water circuit for the moulds when the bottle production process
so requires.
The circuits can be distinguished from the hydraulic panel (see
drawing page 53).
2-
ROTATING JOINTS
These are two rotary devices allowing water to pass between the fixed part of
the box to which the hydraulic panels hoses are connected and a mobile part
connected to the drilled block.
The cold water rotary union is a double-passage manufactured unit with a fixed
central tube.
Sealing is obtained by the rotation of the two extremely flat sealing faces against
one another, held in contact by the action of a bellows spring, together with the
pressure of the fluid conveyed through the seal.
The rotary union is mounted water distributor. It is designed to convey water at
temperatures of up to 80¡C, therefore, it is isolated from the former by Teflon sleeves.
This is a drilled shaft mounted in the case by means of bearings and connecting
the ports of the mould circuit to those of the unit connected to the hydraulic
panel.
The two circuits are isolated by seals.
CAUTION:
The quality of the seals will not allow their use "dry".
The layout of the circuit will still permit the pressurizing of the
rotating joint.
Do not run with a hose disconnected.

VIII - TRANSFER UNIT
The transfer unit includes:
- A preform transfer wheel:
A transfer wheel fitted with 3 arms ensures that the hot preforms pass into the
blow moulds when they leave the oven exit. Each arm is equipped with a gripper
fitted with 2 articulated fingers which catch the preform above the neck ring,
when the spindle releases it. The preform held in this way is transferred by arm
rotation into the blow mould.
The motion is generated by cams.
- Preform ejection device:
The manual ejection of preforms is obtained from the control panel and enables
the operator to eject preforms before they enter the moulds or to check a part of
the transfer adjustments in automatic mode, by removing preforms before they
enter the moulds.
On option, the automatic ejection of preforms is actuated if the preform
temperature read by the infrared camera is incorrect.
- A bottle transfer wheel:
It takes the bottles out of the moulds and puts them onto the outfeed wheels.
The bottle transfer wheel is identical to the preform transfer wheel.
- A bottle ejection device:
The bottle ejection is a device identical to that of the preform ejection. It is
completed by a bottle control system by photocells:
- Two photocells control the base width.
- Two photocells control the shoulder width.
In automatic operation, uncorrect bottles are ejected.
In manual operation, it allows the systematic ejection of manufactured
bottles.
- The bottle exit:
This unit includes a notch plate and guides on which the bottle stands.
After the exit guides, a pneumatic conveying device (Jet stream) can be added
conveying the bottles towards a piece of equipment downstream.

IV - TREATMENT OF COOLING SYSTEM WATER
The performance and lifetime of machine components must be preserved using clean
water first analyzed and treated if necessary. This treatment prevent corrosion as well as
scale and sludge deposits.
The hydraulic systems of SIDEL machines are delivered drained and
clean. This is the reason why any acid etching must be avoided, as it
may corrode some steel or copper systems or tightness bushings if the
flushing and neutralization processes are not carried out correctly.
It is advisable to call out a firm specializing in water treatment which will analyze and advise
the best treatment depending on the characteristics of the additional water.
This treatment is performed by means of products which give to the water:
- A pH alkalinization which must be included between 7.5 and 8 : The anticorrosion
product avoids oxide formation which block off systems.
- A tH which must not exceed 35¡ (French).
The treated system water must be checked every three month according to following
methods:
- Checking using pH-paper or a pH-meter.
Each time the pH is higher than 8 (acidity rate), the water system will have to be
drained, rinsed out and filled with a clean water solution added with an appropriate
product.
- Hardness checking through chloride analysis or using a "salinometer".
In order to make sure that the water in the closed system is clean, it is advisable to filter
the filling water by means of a filter cartridge with 0.05 mm-mesh.
If the ratio between the rates of dissolved solids in water system and in the
additional water is higher than 2, it is necessary to drain and proceed as indicated
above.
In addition to that, a biocide treatment is recommended if the system
must be stopped for some time, in order to prevent alga and microorganisms development, which may clog some parts of the machine
and molds.
Glossary :
pH = Hydrogen potential: characterizes the acidity or the basicity of an environment.
Acid if the pH is less than 7 or basic if it is greater than 7.
TH = Water hardness degree.
French TH :
TH degree corresponds to the absorption of 0.10 g of soap per liter of
water and to the presence (for example) of 10.3 mg of CO3Ca.
!
!
English TH :
TH degree corresponds to 10 mg of CO3Ca for 700 cm3 of water.
German TH :
TH degree corresponds to 10 mg of CO3Ca for one liter of water.
Biocide :
A chemical agent that destroys micro-organims.

II - ASSEMBLY AND ADJUSTMENT OF MOULDS
1-
ASSEMBLY OF MOULD GUPM
!
Disassembly and assembly of moulds is easier on the left side of the
machine and made easier by using a lifting plate.
The reference surfaces defining the positions of the two half-moulds are:
Right-hand side: The side surface and the front face of the bracket.
Left-hand side: The front face of the bracket.
1 - Check the cleanliness of the mould contact surfaces then those of the brackets
and position the two half-moulds then lock the unit.
The position in height of the right half-mould is set by positioning stop keyed to
the half-mould and bearing on the right angle-iron.
2 - Put the two screws "C'" of the left-hand bracket in place in order to press the
two half-moulds against the right-hand bracket.
3 - Bring the mould into contact with the right-hand bracket using all screws "A".
4 - Lock screws "A".
5 - Remove thrust screws "C'" from the left-hand bracket and place the peel-off
shims item 6 between the half-mould and the bracket.
6 - Bring the mould into contact with the peel-off shims of the LH bracket using all
necessary screws "C".
7 - Lock screws "C".
8 - Check that the lock operates properly.
9 - With the mould support unit locked, check the clearance at the connectin plane
of the two half-moulds, this clearance should be 0.05 mm outside vents.
If it is not the case:
Check dimensions X and X' at the top and bottom of the mould outside vents.
Use as reference dimension X or X', whichever is the smallest. Subtract
0.05 mm from the result to determine the thickness of the shims item 6.
NOTE: Fixing screws do not undergo any particular effort and will be
thentightened at the nominal torque corresponding to their diameter
and grade class.

ASSEMBLY OF GUPM MOULD WITH COMPENSATED PRESSURE
!
machine and made easier by using a lifting plate.
Prepare on the workbench the compensation systems (2 sets per mould):
Place the 6 compensation screws mark 6 in cover mark 4.
On each of these screws, position 10 flexible washers, opposed to each other,
so that the washers at the far end have their larger diameter facing outward.
Install the sole-plate mark 3 and tighten screws mark 4 completely by aligning
one of the sides of the screw head parallel to the cover edge. These screws set
a 1 mm pre-adjustment play between the cover and the sole-plate.
These systems, thus prepared, do not need to be disassembled when a mould
set is changed.
Assemble the 2 angle-plates mark 1 and 2 on the left mould support-plate, fix them by
means of FHC/90 M10x16 screws.
Fix the 2 compensation systems to the angle-plates.
Check the cleanliness of the contact surfaces of the mould as well as those of angleplates.
The right half-mould has its position determined by three supports.
In height, at the front side, it rests on the mould support-plate through a metal plate
added and pinned to the mould.
The other supporting sides are the side part and the front side.
1 - Place the right half-mould in the right angle-plate.
2 - Bring the half-mould in contact with the angle-plate by means of all "A" and
"B" screws.
Caution: Do not tighten screws.
Sligthly tighten "A" screws.
Clamp "B" screws. Clamp "A" screws.
3 - The left half-mould, or the angle-plate according to the case, is provided
with an oÕring placed in a groove. This oÕring delimits then a chamber which
will receive air at the blow pressure to perfectly apply the two half-moulds
against each other.
The left half-mould, equipped with two pinned slides, rests on the left angleplate through two bronze pads which act as slides.
4 - Place the left half-mould in the angle-plate, by inserting the two peelable
shims mark 16, and fix it by means of screws mark 10.
5 - Adjust fixing screws so that a 0.5 mm play can be measured between the
sole plate, mark 3 and the cover, mark 4.
There must be a play on the mould mating surfaces, out of vents:
0.1 mm for moulds whose operating temperature is lower than 50¡C.
0.15 mm for operating temperatures higher than 50¡C.

In the case of a small mould, position in the lower hole provided for the
fastening of large moulds, the special M10 screw with 6 sides of 13 mm.
Fix the stop-Bar of the head screws by taking care that one of the sides of
each head screw is aligned parallel to the cover edge.
Note: The fixing screws do not undergo any particular stress and will be
then tightened to the torque corresponding to their diameter and
grade.
Manually assemble the mould base and lock the mould support unit.
Carry out the connections of the heating system and bring the moulds to
their operating temperature.
Check how locking operates.
- 78 -
III - MOULD OPENING/CLOSING
The toothed part is installed on its shaft via a cone ring. It is used to adjust the mould
closing device.
Any misadjusted roller will trip a safety device and cause the machine to stop.
Adjustment procedure:
- With the mould locked, gradually release the screws (by turns on opposite screws) from
the cone ring (3) of the pinion (2), and unlock it by tapping slightly on the screws to free
the misadjusted arm : this will enable the roller to go past the mould opening/closing
cams without any damage to the machine.
- With the mould locked, bring the roller (5) to be adjusted to the outlet of the mould
opening/closing cam, at tool level.
- Install the dummy cam of the tool (1) and tighten the locking screws (17).
- Bring the roller (5) against the dummy cam of the tool (1) : the clearance must be
0.02 mm.
- Tighten the cone ring.
Gradually tighten the screws with a torque wrench, according to levels and
alternately on opposite screws, starting from the two screws located on both sides
of the slot.
First level :
slightly torque to obtain the precise clearance between
the roller and the tool.
Second level :
torque to 7 Nm.
Third level :
torque to 14 Nm.
Fourth level :
check all the screws successively to obtain 14 Nm.
- Lower the dummy cam of the tool (1).
NOTE : The electrical safety device prevents the machine from starting if the
tool is not set to low position.

IV - ASSEMBLY AND ADJUSTMENT OF BASE MOULDS
In the case of the moulds being changed, it is necessary to use base mould raised sections
adapted to the mould arrangement.
machine.
!
-
On each base mould unit, remove the raised section and the existing base mould.
Check the contacting surfaces for cleanliness.
Place slightly greased O-rings in the spot facing.
Place the raised section and the bottom of the mould on the support.
Approach the attaching screws without tightening.
Insert the base in the mould and hold it there while closing and locking the mould.
Tighten the raised section and base mould attaching screws.
Open the mould and operate several times with the bottom in place to make sure
it is correctly aligned.
- Once all mould bases are assembled, bring moulds and mould bases to their
operating temperature.
- Check that the locking system operates properly.
IMPORTANT:
- The mould incorporates a groove which receives the base mould shoulder,
supporting the pressure forces caused by blowing and centering the bottom.
It forms a wearing part.
- The taper bearings are for safety only and must not come into contact when the
mould is closed and must not be used for positioning the base mould for height.
- The mould base is correctly adjusted when the latter drops by 0.05 mm when the
roller leaves the cam.
However, it may be necessary to readjust the height of the peel-off shim placed on the yoke
if there are problems of dilatation:
Indeed, in the case of light alloy molds operating hot, dilatation phenomena can be of
several tenths of millimeter.
After any intervention on adjustments of mould base and systematically every
120 hours, check the fall value when the roller leaves the cam. 0.05 mm must be
found (moulds in operating temperature).
- 81 -
V - ASSEMBLY AND ADJUSTMENT OF BLOW NOZZLES
1-
ADJUSTMENT
Once the blow nozzle has been mounted on the hollow rod, loosen the 4 attaching
screws of the blow nozzle on the mobile wheel.
Insert a preform in the mould and lock it.
Lower the blow nozzle into the neck of the preform while centering it. The preform
should be slightly free.
Lock the blow nozzle in that position.
2-
CHECKING THE TIGHTNESS
To be able to check the nozzle and valve tightness, it is possible to set a 40-Bar blow
in adjustment mode with the doors open.
- Ensure that no blowing valve is open, particularly on those moulds wich could be
incorrectly locked.
- Place items in the moulds of the station to be checked, lock carefully. Close doors.
- At the control station, put the machine on blowing operation.
- Open the doors so as to move the valves of those stations to be checked and lock,
first in pre-blow - then in blow position. Check for leaks.
- Again close all valves.
- Switch off blowing at control station.
!
3-
WARNING: Never force mould unlocking whilst under pressure.
CHANGE OF SEALS
* PLUG:
Insert the o-ring in the groove, deform the heart-shaped sealing band in order to
place it on the o-ring, while complying with the assembly direction (ridge on
pressure side).
* PISTON:
Once the o-ring has been inserted in the groove, use the necessary tools to
assemble the sealing band.
Before assembling the hollow rod on the cylinder, calibrate the seal which will
have dilated considerably during assembly, the use of a gauge enables the seal
to take position back in the groove.
On assembly, be sure to insert the hollow rod in the liner on the chamfer side
rather than on the liner o-ring side.

VI - ADJUSTMENT OF STRETCHINGS
1-
ADJUSTMENT OF STRETCHING CYLINDER PRESSURE
Operation with preforms
Adjust the pressure reducer to ensure preform stretching without losing the contact of
the cam (about 7 Bars).
For safety reasons, these pressures are always higher than 1 Bar compared to that
required.
2-
STRETCHING ADJUSTMENT
The stretching system is composed of a pneumatic cylinder, the rod carries along a
slide on which the stretching rod is fitted.
Before any adjustment, the shock absorbers must be checked for absence of
bouncing.
When the cylinder is compressed, we must have 0.5 mm between the roller and the
horizontal part of the stretching rod. It is possible to perform an adjustment by acting
on the sleeve, on ball-joint side.
The stretching rod is fixed by a chuck ring fitted loose on the slide to avoid alignment
requirements. A play of about 0.2 mm must be present.
The stretching rod must be height adjusted according to the mould and the preform
utilized.
a) Measure the thickness "E" from the preform bottom, off the injection point.
b) Open the 2 doors on the manual transmission side.
c) Release the brake by means of the pneumatic switch, located on the right
side.
d) Using the manual transmission, bring the relevant unit in front of you.
e) Remove the crank handle.
f) Lock the brake by means of the pneumatic switch.
g) Raise the stretching rod.
In case of assembly of moulds smaller than the previous ones, set it to high
position.
h) Measure the thickness "E" of the preform bottom the injection point excluded.
i) Modify the value on the dipstick by adding to "L" the 2/3rds of the thickness
"E" of the preform bottom.
j) Adjust the stretching rod to this new value: L + 2E .
3
k) Tighten the chuck ring for good.
l) Reassemble the coupling without forgetting to tighten again the other end.
m) Put the stretching back in high position.
- 84 -
Particular check of stretching equipped with a stop:
When the blower is designed to manufacture several capacities, a stop system
with a hydraulic shock absorber is assembled on the guiding columns of the
stretching slide.
To adjust the stop, proceed as follows:
* Supply the pneumatic cylinder with an external air supply at a pressure
of 6 Bars so that stretching be set in higher position.
* Untighten the four fixing screws of the two supporting-plates on the
columns.
* Possibly, lower the set thus released in order to position the adjusting
tool corresponding to the item to be manufactured.
* Move the set until the tool rests against the slide.
* In this position, clamp the four screws.
* Remove the adjusting tool.
It is not necessary to adjust again the stretching rod. If however this adjustment
proved to be necessary, proceed as indicated in paragraph 4.
3-
ADJUSTMENT OF PREBLOWING AND BLOWING PRESSURES
Preblowing:
It allows the bottle to be simultaneously blown and stretched, and the end of the
stretching rod to move with the preform base. This value depends on the preform
used and can be between 5 and 10 Bars.
Blowing:
At the end of the preblowing, when the bottle has been perfectly shaped, the
blowing pressure is connected to the bottle. This pressure is about 15 to 20 Bars
for correct bottles with a spherical base and with a "champagne bottle" base, and
between 30 and 40 Bars for petaloid bottles.
4-
ADJUSTMENT OF PREBLOWING AND BLOWING CONTROLS
When adjusting valve opening cams, the positioning is adapted according to the item,
in order to obtain a correctly stretched and blown bottle.
Usually, it is necessary to bring forward the preblowing action in relation to the
beginning of stretching. In the same way, it is also necessary to delay the blowing in
relation to the end of the stretching.
For more details concerning these adjustments, please refer to the adjustment data
sheet.
Point 0 - Point 10
The precise beginning of blowing in relation to stretching mainly determines the
quality of the item produced, namely as far as the material distribution is concerned.
First of all, determine the beginning of active stretching called Point 0.
- After having adjusted the stretching rod, put a preform into the mould
concerned.
- Uncouple the pneumatic cylinder coupling, so that stretching slide may slide
down by gravity.
- 85 -
- Manually rotate the blow wheel very slowly whilst examining the stroke of he
stretching roller and stop as soon as the roller is no longer carried on he cam.
* We are at the beginning of active stretching: This is point 0.
Position the three-way valve lever so as to obtain the distance of 95 mm between the
body of the valve and the underneath of the roller, which corresponds to the beginning
of preblowing.
!
Put the preblowing cam in active position by using an external
compressed air supply.
- Remove the fastening screws of the preblowing cam support and move it into
contact with the roller of the three-way valve.
- Fix the cam.
- Opposite the pointer, make a mark to indicate point 0.
Remove the preform, then go on rotating the blow wheel slowly and stop as soon as
the roller is no longer carried on the cam.
* This position corresponds to the end of active stretching this is point 10.
As above, determine the new location of the preblowing cam and opposite the pointer,
make a mark to indicate point 10.
Then divide the zone thus defined into 10 equal parts.
Mark a few graduations before point 0.
* The machine includes an angular marking in degrees which must not be
mistaken for the marking which has just been done.
* The values of the angular positions of points 0 and 10 are mentioned on the
running in sheet.

STRETCHING CONTROL VALVE ADJUSTMENT
- Bring the valve (C) into the active part of the cam (A).
- Untighten the screws (B) securing the valve (C) without removing them.
- Place a 23.5 mm thick shim (D) between the roller (E) and the body of the valve
(C).
- Bring the roller (E) into contact with the active part of the cam (A).

VII - ADJUSTING THE BLOWING PRESSURE
Blowing pressure is obtained by adjusting the high pressure reducing valve found on the
pneumatic board.
This is done by filling the dome at a pressure slightly higher than that required downstream.
Proceed as follows:
NOTE: There are two needle valves for internal filling: The upper valve opens in
the dome. The lower valve opens in the supply line. A filling duct links
these valves.
Use a hexagonal monkey wrench for the adjustment:
1 - Close the supply needle valve. Exhaust the air from the dome by opening its
needle valve.
2 - Close the dome needle valve.
3 - Slightly open the high pressure air intake valve to bring the pressure to the
regulator inlet at a low flow rate.
4 - Open the supply needle valve by about one and a half turns. This opens the
filling duct to the inlet pipe. The needle valves are not tight, and this means that
there is a slight leak when the dome is being filled.
5 - Slowly open the dome needle valve, monitoring the manometer which shows
the outlet pressure.
6 - Once the required outlet pressure is obtained in the duct, close the dome
needle valve.
7 - Close the supply needle valve.
8 - Check that the dome and supply needle valves are closed properly, but do not
exceed a torque of 3.4 Nm. Too high a torque on the needle valves could cause
distortion or wear due to friction, and leaks.
9 - Slowly open the outlet stop valve until it is in open position.
The pressure reducing valve filled internally is now in operation.
10 - If the outlet stop valve is not tight when closed, the outlet pressure can be
reduced by slightly unscrewing the dome needle valve, to let the air escape
from the dome. When the outlet pressure is at the required level, close the
dome needle valve.

VIII - ELECTROMAGNETIC BRAKE ADJUSTMENT
1-
DESCRIPTION
An eletromagnetic brake, mounted at the motor reducer end of shaft, is used to stop
the machine immediately if the machine safety device is tripped or after a time-delay
in the case of an intentional stop.
The system is idle when the coil is de-energized. In this case, the springs (5) apply
their pressure to the mobile armature (2) which locks the disk (4) against the fixed
plate (6).
The shaft via the core (8) is locked by the disk (4).
When energized, through electromagnetic effect, the coil (1) makes the mobile
armature (2) apply against the electro-magnet (3). No stress is then exerted against
the disk, thus enabling the shaft to rotate freely.
A microswitch detects the movement of the mobile part and enables the moto-reducer
to be energized at start-up.

MANUAL UNLOCKING
With the equipment de-energized, the brake is locked.
The lever (A) enables the disk (4) to be released manually, applying the mobile
armature (2) to the electro-magnet (3). The shaft can turn as long as pressure is
exerted on the lever.
A
3
ADJUSTMENT OF AIR GAP
The air gap is measured between the mobile armature (2) and the electro-magnet (3).
The wear of brake linings carries along the increase of the gap. In practice, before the
maximum value (0.9 mm) is reached, it is necessary to adjust the brake. After a
number of settings, any displacement is no longer possible and the disk must be
replaced.
Adjustement of the air gap:
- Loosen the securing screws by one turn.
- Slightly unscrew the adjusting screws (5) by the necessary value.
- Then lock the securing screws according to the tightening torque:25mN.
- The value of the air gap must be 0.3 mm.
- Proceed to several operations and check the value of the air gap.
4-
ADJUSTMENT OF POSITION SWITCH
Actuate the adjusting screw (B), so that there is no failure displayed on the control
station (the adjustment of the air gap has already been performed).

IX - MEMBRANE CONTROL VALVE
1-
Piston adjustment:
Dimension "A" between the piston and arcade must be greater than the stroke of the
valve because, otherwise, in the low position, the piston will abut on the arcade: The
tightness of the valve on the lower seat would be imperfect.
The nominal adjusting dimension "A" must be 14.5 mm in the idle position (control
depressurized).
This dimension "A" is obtained by adjusting the piston nut. During adjustment, be sure
not to turn the rod because the rotation of the valve on the upper seat could cause it
to seize and consequently give rise to leakage.
2-
Pilot pressure:
To use the valve at a pressure of 40 Bars, the pilot pressure must be adjusted
between 9 and 10 Bars.
3-
Stuffing box:
After several hours of operation, slightly loosen the nut on the stuffing box to prevent
leakage.
4-
Leakage:
Whenever leakage is observed:
1 - Check for the point of leakage:
* At the stuffing box.
* On the upper seat (machine under pressure).
* At the lower seat (machine connected to purge).
2 - Check the load pressure.
3 - Check the pilot pressure.
4 - Check the adjustment dimension "A" (must be 14.5 mm).
5 - Check whether the piston and piston nut are loose.

X - TRANSFER ARM ADJUSTMENT
1-
ADJUSTMENT OF TRANSFER ARMS ON BENCH
During a mechanical incident, one or more transfer arms may become misadjusted.
Indeed, the control lever is not keyed onto its pin and a mechanical incident will cause
the parts to slide with respect to one another. This means that the meeting points are
no longer correct.
To regain synchronism, it is necessary to adjust the arms.
The preform and bottle transfer arms are identical, as is their adjustment.
When the plate arms are disassembled, their position must be marked, so that they
can be put back in their original positions, after having been adjusted. Pay attention
to peelable shims which must stay in their original position.
Arm adjustment method:
- Place the arm adjustment tool in a vice.
- Remove the two side springs of the transfer arm to be adjusted.
- Pull half-grippers apart as much as possible.
- Bring the transfer arm onto the adjustment tool.
* The rear part of the slide fits onto the tool and the half-grippers onto the
centring bridge.
Check the position of the roller using thickness shims, a 0.05 mm shim
does not fit, but the roller should be able to turn.
- Immobilize the roller support lever by tightening the clamping screw at a
torque of 35 Nm.
- It must be noted that the castle nut sets the height of the support lever and
must not be used to clamp it.
* The arm can now be refitted on the machine.
NOTE:
Another tool allows the correct position of the roller support lever to be checked
without disassembling the machine arm.
Once in place on the arm (without side springs), check that there is no play larger than
0.1 mm on the two places of contact. If this is not the case, the arm must be
disassembled to be adjusted.
This tool is also used to adjust the grippers:
Once the arm is clamped onto the tool, fit the new grippers. Put them onto the
template and tighten them. Fold down the screw retainers.

From one end to the other on the preform or bottle path, the theoretical reference
below the collar is 1.400 mm with respect to the ground.
The following elements are adjusted according to this reference:
During disassembly for a change in production, the following values should also be
respected:
* Mould..............................................................................................................0/1400
* Preform transfer gripper...........................................................................+ 0,3/1400
* Infeed slotted wheel .................................................................................+ 0.3/1400

- 94 -
NOTE: The adjustment of grippers can only be carried out from a perfectly
"unbuckled" plate at 0.05 mm. Check this buckling with a comparator before
any operation.
Two reference shims are supplied with the machine. These shims are of 29.8 and
30.1 mm for the machines equipped with large mould support units "GUPM".
With the highest shim, and with a preform neck, adjust the gripper height of the
preform transfer-wheel. At the level of the shim we should have
The under part of the neck ring on the GUPM units.
The adjustment is obtained by acting on the peelable shim located between the
transfer arm and the arm support plate.
The adjustment of bottle transfer arms is identical.
With this type of adjustment, it must be noticed a drop of the preform by 0.3 mm when
the gripper dops it into the mould, and a perfect concordance of the gripper with the
groove of the bottle neck before opening the mould.
The height adjustment of the fixed guide of the oven notched wheel is such that the
arm grippers coincide perfectly with the preform groove which leave the oven. The
whole is pinned.

SETTING OF TRANSFERS AFTER REMOVAL OF MOULD SET
The new moulds are adjusted and at the 1.400 mm reference with respect to the
ground.
Remove the transfer arm by locating their positions on the plate.
Remove the transfer arm grippers.
Assemble the new grippers.
Using the arm adjusting tool, check the positions of the levers.
Assemble the arm in the slot of the plate in compliance with the markings made during
disassemble.
Check the height of the grippers.
- If the settings are wrong, first check that the arms have been properly
mounted in their original locations.
- To carry out a new adjustment, the latter can be performed:
*
Either by means of the shims placed between the arm and the armholding plate. A shim thickness will also be added or removed under all
the arms, grippers being at the same height if arms are reassembled
at their original place.
*
Either by acting on the arm-holding plate by means of the with the cone
ring.
In this case, check synchronism of transfers.
Assemble the customizing kit for the slotted wheels and the preform feeding wheel.
- Check the clearance with preform.
Assemble the customizing kit for the bottle exit wheel.
- Check the clearance with bottle.
Adjust the bottle exit guides leaving sufficient clearance either side of the diameter
beneath the neck to prevent the bottles from jamming.

CLEANING CHECKS
- 102 -
I - SAFETY DURING CHECKS AND CLEANING
Only authorized people wearing all protective and safety gear are allowed
to carry out checks and cleaning operations. Furthermore, they shall
check that the power supplies have actually been cut off and drained
before any servicing.
!
In case there are hot parts, the operator must be provided with heatresistant protective gear.
In case checks must be performed when power is supplied, the people
authorized to carry out these operations shall comply with the safety
instructions in force.
- 103 -
II - MAINTENANCE OF THE SBO MACHINES
1-
DAILY MAINTENANCE
Daily maintenance is mainly connected with the remarks made by the operator during
the operation of the machine.
Since the aim of the operator is to ensure the quality and quantity of blown bottles, it
is better to stop the blow moulding machine as soon as possible and solve the
problem, when there is a mechanical incident or if the items produced are of bad
quality. This should be done so as not to prolong efficiency or quality losses
unnecessarily.
For information only, the daily stopping time should not exceed 1 hour in order to
maintain the overall efficiency of the machine.
In order to minimize the loss of material, it is advisable to correct a fault as soon as
possible rather than being subjected to a breakdown. Breaking down means:
- Loss of material.
- Loss of machine efficiency.
- Abnormal wear of parts.
Most daily maintenance takes place whilst the machine is operating and consists in
checking all the parameters indicated on the adjustment data sheet
pre-blowing - blowing - stretching - heating ...
During production run, the operator must check the homogeneity of the items
produced by the various blowing stations, either visually or using some apparatus.
He must also monitor the rate of the machine and the various bottle and preform
transfers.
The daily maintenance of the machine is not considered as fixed, but must develop
according to the operation of the machine and the specificity of the line.
As a general rule, a machine which runs smoothly is not stopped.
On the other hand, it is desirable to use the time during which the downstream
equipment is stopped (if permitted by the number of bottles kept in stock) to check the
machine more thoroughly.
Simultaneous bench work is always preferable and must be used to the full.
The operator must check the oil level in the lubricator tanks of the blow wheel and of
the infrared oven (7 Bar system - cylinder air)
For adjusting the oil flow rate, refer to chart on page 106.
IMPORTANT:
The operator must write all his remarks and observations in a production book. They
will provide the base of a good weekly preventive maintenance.
- 104 -
2-
WEEKLY MAINTENANCE
You do not have to systematically adjust all the mechanical functions and safety
devices during weekly maintenance.
The operator must refer to the machine production book which is the basis of weekly
maintenance.
For your information, stopping time for weekly maintenance with greasing should be
of about 3 to 4 hours for SBO 6.
Weekly maintenance is normally performed by 2 technicians.
3-
CLEANING
It is advisable to do this all week long so as to keep the machine clean.
With a dry cloth, remove the excess grease on the mechanical units.
Clean the glass partitions.
Check that the moulds are clean and if necessary clean them with a cloth moistened
with alcohol or solvent.
Do not use too much polish which ends up rounding off sharp edges.
Clean the brake disc of the blow wheel using a dry compressed air blower and cloths.
4-
CHECKS
Mould bases:
Mould base being at the position of the adjustment tool.
* Check the clearance between the stroke limiting screw of the mould base in
up position and the console 0,15 +/- 0,02.
* Check the clearance between the roller and the adjustment tool a 0,02 mm
schim must no pass between the roller and the tool.
For other assemblies, a systematic control is not necessary if the machine has worked
for a whole week without any trouble.
But, if several problems have occured during the week, the reasons for trouble must
be thoroughly analyzed in order to control the elements in question.
- 105 -
5-
SAFETY DEVICES
It is essential to monitor the following safety devices preventively:
* Preform loading:
Carry out a test with a preform which has a large fault on its neck edge the
preform should be ejected.
* Mould locking:
Simulate a faulty locking with a 10 mm thickness shim fitted between the bottom
part of the left-hand side bracket and the locking roller support: This should
trigger the tripping of the locking cam and set the safety switch. Check with the
relevant controller input.
* Faulty bottle ejection:
With the machine in operation, bring about non blowing or pre-blow audits and
check the operation of the ejection device.
* Brake:
With the machine in operation, without bottle production, bring about a safety
stoppage by pressing the emergency stop button or by opening a door: The
machine should stop correctly on 1.5 to 2 stations.
6-
ADJUSTMENTS
It is necessary to adjust the mechanical units for which the checks have turned out to
be faulty.
* Locking mechanisms:
Adjust the pressure strength of the holding pad so that the locking stress does
not make the cam tip and that the locking mechanism remains in a locked
position.

Lubrication procedure.
- Switch off the oven and the heating zones.
- The lubrication takes place in 2 steps (see figure):
* 1st step: At the oven outlet, after turning the spindles upside down (nose
downwards).
* 2nd step: At the rear of the oven (nose upwards).
- The lubrication takes place when the spindles are in one of the 2 toothed wheels.
- The extender must be oriented towards the visible part of the sphere.
When applying grease, one impulse is sufficient because an excess of
grease would cause its running on the spindle nose.
