Definitions
- the invention relates to an installation for manufacturing containers made of thermoplastic material comprising a thermal conditioning station and a molding station.
- the invention relates more particularly to an installation for manufacturing containers made of thermoplastic material from preforms, the installation comprising:
- a preform thermal conditioning station which is equipped with a preform conveyor, the station comprising a first drive shaft of the conveyor;
- a molding station which is equipped with a carousel carrying a plurality of molding devices which are fed in preforms by the conditioning station, the station comprising a second drive shaft of the carousel;
- thermoplastic containers such as bottles, flasks, etc.
- the manufacture of thermoplastic containers is performed during a step of forming containers in the form of a blank, which are sometimes called preforms.
- the preforms Prior to the implementation of the forming step, the preforms go through a thermal conditioning step. During this step, the preforms are heated in a thermal conditioning station, or oven, so as to give them a sufficiently malleable structure for the forming process.
- preforms are then transferred to a molding station which has a plurality of molding devices. Each preform is introduced into a mold of the molding device.
- the molding device also comprises means for blowing or stretch-blow molding.
- the installation has many elements that are adapted to the format of the final container to obtain. These elements are sometimes called "personalization elements". Among these elements, one can for example quote the molds of the molding station. Preforms gripping means can also be mentioned to enable the conveying of preforms having necks of different sizes through the thermal conditioning station.
- the body of the preforms is heated for a predetermined period.
- the body of the preforms may be heated in a non-homogeneous manner according to a determined profile.
- they are conveyed in a heating tunnel of the conditioning station, along a predetermined path.
- the preforms thus heated are transferred from an output of the thermal conditioning station to an entry point of the molding station.
- the molding devices are moved so that the final containers are demolded at an exit point of the installation.
- the molding devices are for example mounted on a carousel.
- a blow molding or stretch blow molding cycle is substantially faster than a heat-conditioning cycle of a preform.
- the thermal conditioning station receives substantially more preforms as the molding station.
- the molding station comprises a dozen molding devices while the conveyor of the packaging station is capable of accommodating a hundred preforms.
- the preforms are moved through these two stations synchronously so that each preform is heated to a precise temperature when it is transferred to a molding device.
- the carousel of the molding station and the conveyor of the conditioning station are rotated by a common drive motor.
- the motor generally drives the carousel of the molding station, the drive movement being transmitted to the conveyor of the conditioning station by means of transmission means according to a precise speed ratio, said manufacturing, allowing the synchronous operation of two stations for the manufacture of containers.
- a so-called “non-reference" pitch of the molds is defined, which is equal to the angle of rotation of the carousel for a molding device to replace the directly preceding molding device at the level of the carousel. entry point of the molding station.
- a running step of the gripping means said "no manufacturing”, which corresponds to the movement of the conveyor necessary for a gripping means to take the place of the gripping means directly preceding the output of the the thermal conditioning station.
- the manufacturing speed ratio makes it possible to synchronize the carousel and the conveyor so that the movement of the molds of a reference step corresponds to the movement of the gripping means of a manufacturing step.
- the motor When changing format, the motor is controlled so as to scroll the molding devices one after another in front of a first replacement area.
- the engine marks a stop to allow replacement operations to take place during a format change step. This is not a problem because the mussels are few and they can be changed one by one without taking too much time.
- the replacement area is likely to accommodate two molds. We can then scroll the molds of two reference steps between each replacement operation.
- the gripping means must successively mark a stop in front of a second replacement zone to be replaced.
- the gripping means are very numerous, it is therefore advantageous to be able to replace several during each replacement operation.
- the gripping means being compact and light enough, it is easy to simultaneously receive a series of several gripping means in the second replacement zone.
- the gear ratio of the transmission mechanism does not allow to scroll simultaneously the carousel of a reference pitch and the conveyor of a replacement step.
- the invention proposes an installation of the type described above, characterized in that the transmission means comprise controlled elements for selectively transmitting the movement between the first shaft. and the second drive shaft is in the first gear ratio, or in at least one second gear ratio.
- the transmission means comprise: a first transmission mechanism according to the first gear ratio between the first drive shaft and the second drive shaft;
- At least one gear selection device which selectively couples the second drive shaft with the first drive shaft via the first transmission mechanism or the second transmission mechanism
- the gear selection device is likely to occupy a position of "neutral" in which the first shaft is not coupled with the second shaft;
- each transmission mechanism comprises:
- Temporary coupling means of the second freewheel which can be controlled between an engaged state in which the freewheel is connected in rotation with the drive shafts, and a disengaged state in which the rotational link between the free wheel and the drive shafts is interrupted;
- the free wheel is carried directly by one of the drive shafts;
- the free wheel is carried by the drive shaft of the conveyor;
- the free wheel is carried by an intermediate shaft between the two drive shafts; -
- the free wheel is rotatably connected with at least one of the drive shafts via at least one flexible connecting member, such as a belt;
- the temporary coupling means are formed by a dog clutch system
- the coupling means are formed by a friction clutch system.
- FIG. 1 is a top view which schematically shows a container manufacturing plant made according to the teachings of the invention
- FIG. 2 is a side view which shows the means for transmitting movement between the carousel and the conveyor which are made according to the teachings of the invention.
- FIG. 1 shows a plant 10 for manufacturing containers made of thermoplastic material from preforms (not shown).
- Such preforms are generally obtained by injection and have a tubular cylindrical body closed at one of its axial ends, and which is extended at its other end by a neck, also tubular.
- the neck is usually injected so as to have already its final shape while the body of the preform is called to undergo a deformation relatively large to form the final container during the forming step.
- the installation 10 comprises a preform thermal conditioning station 12 which is equipped with a conveyor 14 comprising a plurality of means (not shown) for gripping preforms.
- the thermal conditioning station 12 more particularly comprises a fixed tunnel which is equipped with means (not shown) for heating, such as infrared lamps.
- the tunnel is traversed by the conveyor 14.
- the preform gripping means are arranged one behind the other on the conveyor 14 so as to be spaced apart from each other by a determined pitch.
- the gripping means are intended to grip the preforms by their neck so as to allow the free body to be heated by the heating means.
- Each gripping means is adapted to the dimensions of the neck of the containers during manufacture. Depending on the container size, the neck may have different diameters and / or heights. These gripping means thus form personalization elements that must be changed during a container size change step.
- the preforms are thus conveyed in a queue along the tunnel from an inlet 16 to an outlet 18 of the tunnel, so that their bodies are heated to a predetermined profile.
- the conveyor 14 is for example formed by a chain of which each link carries a gripping means.
- the conveyor chain 14 is closed around two guide wheels 20, 22 which are arranged at two ends of the packaging station 12.
- the first guide wheel 20 is rotatably mounted about a vertical "A" axis via a first drive shaft 24, while the second guide wheel is rotatably mounted about an "B” axis. vertical.
- the first drive shaft 24 will hereafter be called “conveyor shaft 24".
- the inlet 16 and the exit 18 of the tunnel are arranged close to the first guide wheel 20. According to this configuration, the tunnel here forms a "U", the preforms making a turn at the second guide wheel 22.
- the first guide wheel 20 forms a driving wheel 20 for the conveyor 14 while the second wheel 22 forms a driven wheel 22.
- the rotating drive means 24 of the conveyor shaft will be detailed later.
- the molding station 26 comprises a carousel 28 which is rotatably mounted about a vertical axis "C" via a second drive shaft 27.
- the second drive shaft 27 will be referred to hereafter as “carousel shaft 27".
- the carousel 28 carries at its periphery a plurality of molding devices (not shown).
- Each molding device comprises a removable mold which delimits a molding cavity.
- the molding cavity is intended to receive an outgoing preform still hot from the station 12 of conditioning.
- Each molding device also comprises a nozzle (not shown) associated blow molding or stretch-blow molding which is intended to give the container its final shape by pressing the malleable walls of the preform against the walls of the mold cavity by introduction of a fluid under pressure through the neck of the preform.
- the nozzles have elements that are adapted to the dimensions of the neck of the container being manufactured. These personalization elements are also likely to be replaced during a format change step.
- the carousel 28 is rotated to allow the preforms / end containers to move from an entry point 29 to an exit point 31.
- a new preform can begin the molding step while the previous preform has not yet completed its forming cycle in the associated molding device. This makes it possible to maintain a high rate for the mass production of the containers.
- the molding station 26 also comprises a transfer wheel 30 which is interposed between the outlet 18 of the conditioning station 12 and the entry point 29 on the carousel 28.
- the transfer wheel 30 is rotatably mounted about an axis "D" vertical via a central shaft 32, which will be called thereafter "transfer shaft 32".
- the transfer wheel 30 has gripping members (not shown) at its periphery for transferring the hot preforms from the conveyor 14 to a mold of the carousel 28.
- the molding station 26 also comprises a wheel 33 for evacuating the final containers which is arranged to receive the final containers at the exit point 31 of the carousel 28.
- the evacuation wheel 33 has a structure similar to that of the wheel 30 transfer.
- the conveyor 14, the transfer wheel 30 and the carousel 28 must operate synchronously so that the preforms run continuously from the inlet 16 of the conditioning station 12 to the outlet point 31 of the molding station 26.
- the carousel 28 is rotated by a drive motor 34 which rotates the shaft 27 of the carousel.
- the rotational movement of the carousel 28 is transmitted along a kinematic chain first passing through the transfer shaft 32, then the movement of the transfer shaft 32 is transmitted to the conveyor shaft 24.
- the motion transmission along the drive train from the carousel shaft 27 to the conveyor shaft 24 is performed by transmission means 35.
- the transmission means 35 comprise, for example, belts and / or gear trains or any other known mechanical transmission means.
- the transmission means 35 transmit the movement between the carousel shaft 27 and the conveyor shaft 24 in a first gear ratio "R1" determined, said ratio "R1" manufacturing speeds.
- the first ratio "R1" manufacturing speeds is set so that all these movable elements are synchronized during operation in a "manufacturing" mode during the manufacture of large-scale containers.
- the motor 34 operates continuously at a constant speed so as to cycle the preforms without interruption from the input 16 to the exit point 31.
- the motor 34 is then controlled so as to scroll each molding device step by step in front of a first replacement zone according to the first "PO" reference step, the motor 34 marking a stop time at each step to allow time. to replace the mold and other personalization elements.
- the motor 34 is also controlled so as to scroll step by step a series of gripping means of the conveyor 14 in front of a second replacement zone according to a second pitch "P2" called replacement.
- the second replacement zone is capable of accommodating a series of several adjacent gripping means. With each step "P2" replacement, the next series of gripping means takes the place of the series that has just occupied the second replacement zone before the engine marks a new stop to allow the replacement of all means of the series which is stopped in front of the second replacement zone.
- the second step “P2" replacing the gripping means is substantially larger than the first step "P1" of manufacture.
- the first step “P1" corresponds to a movement of the gripping means one by one in front of the replacement zone
- the second "P2" replacement step corresponds to a movement of the gripping means by series, for example ten by ten, in front of the replacement area.
- the rotation of the carousel 28 of the first "PO” reference step causes the rotation of the conveyor 14 of the "P1" step of manufacture which does not correspond to the second no "P2" replacement of the gripping means.
- the rotation of the carousel 28 of the first "PO” reference step causes the rotation of the conveyor 14 of the "P1" step of manufacture which does not correspond to the second no "P2" replacement of the gripping means.

- the first gear ratio "R1" corresponds to a running of the molding devices and the gripping means in a synchronized manner during operation in the "manufacturing" mode of the installation 10 so that the rotation of the carousel 28 of a no "PO" reference causes the rotation of the conveyor 14 of the first step "P1" of manufacture.
- the preforms carried by each of the gripping means are successively received in a corresponding mold.
- the first ratio "R1" of speeds between the carousel shaft 27 and the conveyor shaft 24 is equal to 0.5, in other words, the conveyor shaft 24 performs a turn when the carousel shaft 27 performs two turns.
- the second speed ratio "R2" corresponds to a movement of the molds and gripping means in "format change” mode so that the rotation of the carousel 28 with a reference pitch “P0" causes the conveyor 14 to rotate. second step “P2" replacement.
- the second ratio "R2" of speeds between the carousel shaft 27 and the conveyor shaft 24 is equal to 5, in other words, the conveyor shaft 24 performs five laps when the carousel shaft 27 makes a turn.
- control members are arranged on the kinematic chain portion which is between the transfer wheel 30 and the conveyor 14.
- control members may be arranged on another portion of the drive train between the carousel shaft 27 and the conveyor shaft 24.
- the transmission means 35 thus comprise a first transmission mechanism 36 according to the first gear ratio "R1" between the conveyor shaft 24 and the carousel shaft 27.
- the first mechanism 36 here comprises a first toothed drive wheel 38 which is carried in rotationally manner by the transfer shaft 32 and a second toothed drive wheel 40 which is carried by the conveyor shaft 24. Subsequently these two wheels 38, 40 will be called respectively “first primary wheel 38” and “second primary wheel 40".

- the second primary wheel 40 is capable of being secured in rotation with the conveyor shaft 24 by means of temporary coupling means 44 which are carried by the conveyor shaft 24.
- the temporary coupling device 44 is for example formed by a dog clutch system between a dog element 46 which is mounted vertically sliding and rotatably connected to the conveyor shaft 24.
- the element 46 of dog is likely to be fitted vertically with the wheel 40 primary.
- the dog element 46 is thus capable of being controlled between a lower declutching position in which the primary wheel 40 is free to rotate on the conveyor shaft 24, and an upper clutch position in which the primary wheel 40 is integral in rotation with the conveyor shaft 24 via the dog element 46.
