Apparatus and method for producing a glass / plastic composite

description

The invention relates to a method for producing a glass / plastic composite, consisting of an at least uniaxial curved glass pane, preferably made of tempered safety glass, and one or more each comprising a self-adhesive layer of adhesive plastic film and a corresponding device.

Such methods are known, for example, from EP 0 403 321 A1 or EP 1 114 001 A1.

The object of the present invention is to provide a method and a device in which a high positioning accuracy between the glass pane and the plastic film can be achieved with nevertheless high output.

This object is achieved in procedural terms by the combination of the steps specified in claim 1 and in device-technical terms by the features of claim 24.

Advantageous developments are specified in the subclaims. The method according to the invention comprises the combination of the following steps: an activation step in which an automatic activation of the adhesive layer takes place, a film receiving step in which the automatic picking up and transfer of the plastic film to be adhered to the glass sheet to a film supply unit takes place, a feeding step, in which the plastic film is brought to a joining position, a disk-receiving step, in which the automatic picking up of the glass pane takes place in a holding device, a positioning step in which the automatic positioning of the glass pane takes place within the holding device and / or relative to the plastic film to be stuck, and a Joining step, in which the automatic gluing of the plastic film on the glass is done.

By "glass sheet" is meant, for the purposes of this application, a monolayer or multilayer element, including such an element wherein the material varies within or over the layers, the layers being inorganic glass, especially silicate glass and / or transparent plastic ,

As a plastic film is a film of various materials into consideration, specifically, the plastic film to be adhered also include a plastic material of the following group or consist of such a material: polyester (PE), polyethylene terephthalate (PET), polycarbonate (PC), polymethyl methacrylate (PMMA) and ethylene / methacrylic acid copolymers.

The plastic film (50-500 microns) is preferably made of either a transparent, translucent, mass-colored or coated plastic film, which is provided with a scratch-resistant coating, which later faces the vehicle interior. On the surface facing the glass, an adhesive layer (2-100 microns) is applied, which is protected with a release liner release film. The plastic film can also be constructed from layers of several different plastic films.

The activation step for activating the self-adhesive layer of the plastic film can be done before, simultaneously with or after the film-receiving step, that is, the activation of the adhesive layer could already on the film stack, during the Take the plastic film from the film stack or even during the feeding step.

In a specific embodiment, the activation step comprises stripping off a protective film covering the self-adhesive layer (release liner).

Preferred dimensions, the removal takes place automatically, in particular via a trigger unit.

In a further preferred refinement, a receiving device receives the protective film via one or more provided adhesive tapes and the withdrawal unit pulls the protective film from the adhesive layer, if necessary with the assistance of a film feed unit. The adhesive tapes can be provided for this purpose on one or more supply rolls. After the protective film has been removed, the adhesive tape (s) are wound up on a take-up roll together with the removed protective film. The number of supply rolls on a preferably common shaft depends on the width of the plastic film. In any case, corresponding to the number and spacing of the supply rolls on the common shaft to provide a corresponding number of take-up rolls in a corresponding distance.

In an alternative embodiment, the withdrawal unit can also be designed such that the receptacle of the adhesive tapes is taken over by vacuum suckers. The vacuum cups can either remove the sucked-in protective film (release liner) from the plastic film by means of a straight-line movement or can also pick it up over the peripheral surface of a drum roller. For this purpose, of course, a corresponding vacuum on the receiving surface, tape or roll for the plastic film is necessary so that they are not removed with the protective film.

The joining step may expediently comprise applying the plastic film to the glass pane with at least one application roller. Further preferably, the application roller is adapted to the shape of the at least uniaxially bent glass pane or is even continuously adapted to the shape of the at least uniaxially bent glass pane across the entire joining step. In this last-mentioned alternative, it is thus possible to adapt or change the curvature of the application roller over the process of application in such a way that it is optimally matched to the attachment points or curvature of the glass plate predetermined at the joint line. The film-receiving step may comprise receiving the plastic film from a film stack, in particular from a film stack received in a cassette. The provision of already pre-cut plastic films on a film stack is considered to be a particularly advantageous embodiment of the present invention.

According to another aspect of the present invention, the film-receiving step comprises bringing the plastic film to a joining position via a film supply unit, in which the plastic film and the glass sheet are joined by adhering the plastic film.

According to a further method aspect, it is provided that the receiving device transfers the single plastic film to the film feed unit.

Removing the protective film can be achieved in a variety of ways. In one possible embodiment, during the further transport of the plastic film in the film feed unit to the protective fohe a deviating from the transport direction tensile force is applied, and this can be done in particular on the one or more adhesive tapes of the trigger unit.

In a first alternative embodiment, the film feed unit comprises a conveying roller sized with such a diameter that the plastic film transferred to the conveying roller can be completely absorbed by the peripheral surface of the conveying roller without overlapping itself. In an optional embodiment, this conveyor roller can simultaneously define the application roller and more preferably also represent the single conveyor roller of the film supply unit.

Within the feeding step, on the one hand, the feeding of separated plastic films to the joining position is effected; On the other hand, within the feeding step, the plastic film can be formed into a desired curvature transverse to the transporting direction.

In a preferred embodiment, the transfer to a desired curvature takes place transversely to the transport direction within the feed step gradually, for example, in that a plurality of conveyor rollers are traversed by the plastic film with increasing curvature profile in the conveying direction. In a preferred embodiment, the forces required to form the desired curvature transversely to the transport direction are generated by negative pressure or suction.

In one possible embodiment, the plastic film is transported in the film feed unit on one or more conveyor rollers or on a conveyor belt.

The positioning step of the glass pane may comprise transporting the glass pane along a predetermined transport path, preferably by means of the holding device from a rest position to a joining position in which the plastic film and glass pane are joined by adhering the plastic film.

It can further be provided that the holding device is moved back into the rest position along a second transport path different from the first transport path.

Finally, it can be provided that the holding device holds the glass sheet in a predetermined curvature or by means of the vacuum device and distributed over the predetermined positioning surface suction openings in a predetermined curvature, which is adapted to the curvature of the profile of the application roller of the film feed unit. On the one hand, this makes it possible to process glass panes which exactly follow the curvature predetermined by the holding device. On the other hand, it is also possible, slightly different in their curvature from the predetermined by the holding device curvature bend slightly so that they are brought in the holding device in the predetermined by the positioning curvature glass panes, so that in the joining step, the glass pane always exists with the same predetermined curvature. This has decisive advantages, since the curvature of the application roller can be adapted exactly to the predetermined curvature of the positioning surface of the holding device.

In an optional further development, it is also possible to be able to change the curvature of the positioning surface, for example by changing the suction openings provided on the nozzles by relative displacement of the nozzles relative to one another in their relative orientation, in particular being aligned computer-controlled on an adjustable positioning surface. The curvature of the application roller can also be variable, for example, for a plurality of glass / plastic composites to be produced to a predetermined curvature, in particular likewise computer-aided, be set. Alternatively, it is also possible to change the curvature of the application roller during the joining step in a desired manner.

The joining step may comprise the production of a first adhesive adherend between a leading edge of the glass sheet and a leading edge of the plastic film. The leading edges may be offset from each other, i. the foil edge is e.g. 3 cm inside the glass.

This can be done, in particular, by pressing the glass pane over the holding device with its leading edge on the front edge of the plastic film on the application roller such that a first adhesive contact between the glass pane and the plastic film is produced along the contact line or in this limited contact field.

According to a further preferred aspect, it can be provided that as punctiform as possible is temporarily supported in a line-shaped production of a first adhesive contact between the glass pane and the plastic film by means of pressure means within the application roller.

As already mentioned, the invention also encompasses an apparatus for producing a glass / plastic composite consisting of a glass sheet bent at least uniaxially, preferably of toughened safety glass, and one or more plastic sheets comprising a self-adhesive layer, the apparatus comprising: a receiving device for receiving a glass sheet a plastic film from a film stack, a film feed unit for feeding the plastic film to a joining position, are joined together in the plastic film and glass by gluing the plastic film, a holding device by means of which the glass sheet from a rest position of the

Holding device is brought to the joining position and an applicator roller as part of the film feed unit, by means of which

Plastic film is glued directly or indirectly to the pressed by the holding device to the applicator roll glass. In a preferred embodiment, the device comprises a cassette in which the film stack is accommodated for each individual removal of a plastic film by the receiving device.

In a preferred embodiment, the receiving device comprises one or more adhesive tapes, by means of which the plastic film, in particular via a protective film arranged on the plastic film can be accommodated.

Furthermore, the device may comprise an adhesive layer / activation unit, preferably a trigger unit, which activates the adhesive layer of the plastic film, in particular by peeling off a protective film.

The withdrawal unit can expediently comprise means for detecting the adhesive tape or tapes, in particular a take-up reel, in order to exert tensile forces on the protective film in a direction deviating from a transport direction of the plastic film.

In a first alternative embodiment, the film supply unit can have a plurality of conveying rollers which, facing the plastic film, have a convexly or concavely curved profile deviating from the cylindrical shape. It can further be provided that the degree of curvature of the profile of the conveyor rollers gradually increases in the conveying direction and the last conveyor roller, which also defines the application roller, has a profile adapted to the bending of the glass sheet.

It can further be provided that at least one, preferably several, particularly preferably all conveying rollers, cooperate with a vacuum device, which hold the plastic film via vacuum or suction in each case via openings in the shell of the conveying rollers.

In an alternative embodiment, the film supply unit may comprise a conveyor belt on which the plastic film rests and is brought to the joining position.

In a specific development, it can be provided that a vacuum device generates a negative pressure in a vacuum chamber enclosed by a conveyor belt and two opposing side walls and the plastic film is held in contact with the conveyor belt via openings in the conveyor belt via negative pressure or suction. Alternatively or additionally, the conveyor belt may be guided over conveyor rollers which, facing the conveyor belt, have a convexly or concavely curved profile deviating from the cylindrical shape. In this case, it can further be provided that the degree of curvature of the conveyor rollers gradually increases in the conveying direction and the last conveyor roller, which simultaneously defines the application roller, has a profile adapted to the bending of the glass pane.

Preferably, the jacket of the conveyor rollers is formed of an elastomeric material or comprises a surface of elastomeric material having a specific material thickness and a specific material hardness. The elastomer allows adaptation to the curvature of the glass sheet and at the same time has sufficient hardness to effect a visually distortion-free bond between the glass sheet and the plastic film during the joining step.

In a preferred embodiment, it is provided that the holding device of the glass pane cooperates with a vacuum device, which holds the glass pane within the holding device by means of vacuum or suction via suction openings, which are arranged distributed in a predetermined positioning surface. Possibly. the curvature of the positioning surface can also be adjusted by shifting the relative position of the suction openings, which can be provided, for example, on displaceable connecting pieces.

On or within the applicator roller further pressing means may be provided, which are used, if necessary, to press a leading edge of the applied on the applicator roll plastic film at least partially to a front edge of the pressed by means of the holding device to the front edge of the plastic sheet glass. By means of these pressure means, it is possible to achieve a first, as far as possible, punctually necessary transition into a linear connection between the glass pane and the plastic film, so that certain tensile forces can also be exerted on the glass pane during the subsequent rolling up of the plastic film. The pressure means preferably comprise a hydraulically or pneumatically fillable or expensible, expandable chamber.

FIG. 1 illustrates an embodiment of a plastic film 12 which can be processed to produce a glass / plastic composite in the method according to the invention or in the device according to the invention. The plastic film 12 is coated on one side with an adhesive layer 13. The adhesive layer 13 is initially covered by a protective film 15 (release liner) in the plastic film 12. On the side facing away from the adhesive layer 13 of the plastic film 12, a scratch-resistant coating 52 may be provided, in particular based on polysiloxane or acrylate.

The plastic film 12 may be, for example, a polyethylene terephthalate (PET) or a polyester (PE) film. Alternatively, the plastic film 12 may also consist of another plastic material, for example of polycarbonate (PC), polymethylmethacrylate (PMMA) or ethylene / methacrylic acid copolymers.

2 shows a holding device 14 on which a glass pane 11 (cf., for example, FIG. 3) can be fixed on a precisely defined positioning surface 30. The positioning surface 30 may be multi-axially curved and adapted to the predetermined curvature of the glass sheet 11. Alternatively, it is also possible that the predetermined curvature of the glass pane 11 deviates slightly from the predetermined curvature of the positioning surface 30. If the deviations are sufficiently small, it is possible with the holding device 14 to bring the glass pane 11 into a curvature in accordance with the positioning surface 30.

The positioning surface 30 is defined by a plurality of suction nozzles 42 arranged on a frame 41, specifically via suction openings 38 provided at the distal end of the suction nozzles 42. The suction nozzles 42 are positioned with their suction openings 38 relative to each other such that the desired positioning surface 30 results.

The suction nozzles 42 with the suction openings 38 arranged distally are connected to a vacuum device 29 in such a way that, when the glass pane 11 is resting on the suction openings 38, it is held on the suction nozzle 42 of the holding device 14 by negative pressure or suction. The holding device 14 thus serves to fix the glass pane 11. Further, the holding device 14, the glass sheet 11, which will be described in more detail with reference to the following embodiments, to a joining position or empty return to a rest position for receiving a new glass 11.

FIG. 3 shows a schematic representation of a first embodiment of a device according to the invention for producing a glass / plastic composite.

The device comprises the already mentioned holding device 14, on which a glass pane 11 is already placed or fixed here. Further, a film stack 17 comprising a plurality of plastic films 12 is held in a cassette 18. The plastic films are accommodated in the cassette so that the protective films 15 are each at the top. About a receiving device 35, the plastic films 12 are removed from the cassette 18 individually and spent on a film feed unit 21 to a joining position.

In the embodiment illustrated with reference to FIG. 3, the following arrangement is given or the following sequence is provided. The aforementioned receiving device 35 comprises one or more adhesive tapes 20, which are each provided on a supply roll 37 and rewound after use on a preferably driven take-up roll 36. With a corresponding width of the plastic films 12 more parallel adhesive tapes 20 may be provided, wherein in this case expediently the supply rolls 37 and the take-up rolls 36 are each arranged on respective common shafts. Between supply roll 37 and take-up roll 36, the adhesive tape (or the adhesive tapes) is guided via a deflection roller 39 and a deflection edge 43.

To remove the uppermost plastic film 12 from the film stack 17 received in the cassette 18, the receiving device 35 lowers the at least one adhesive tape 20 onto the film stack 17 and contacts the protective film 15 of the uppermost plastic film 12. For this film receiving step, the receiving device 35 and cassette 18 brought so close to each other that the described contacting of the protective film 15 of the overhead plastic film 12 is made possible by the adhesive tape 20. In the present imple mentation form, the cassette 18 may be formed stationary and the receiving device 35 comprising the at least one adhesive tape 20, the supply roll 37, the guide roller 39, the deflection edge 43 and the take-up reel 36 moved up to the fixed cassette 18 and moved away from it become.

By contacting the protective film 15 by the at least one adhesive tape 20, the uppermost plastic film 12 now adheres to the receiving device 35 and so on the film feed unit 21, the leadership in the present form a conveyor roller, the same time an application roller 16 for application the plastic film 12 defined on the glass pane 11 has. By means of the receiving device 35, the recorded plastic film 12 is lowered onto the application roller 16.

The application roller 16 comprises a roller core 44 and a jacket 27, which is preferably formed from an elastomeric material. In the jacket 27, a plurality of openings 45 are provided, which cooperate with a vacuum device 26. Through these openings 45, which are in flow communication with the vacuum device 26, it is ensured that the transferred from the receiving device 35 on the applicator roller 16 plastic film 12 also adheres to the shell 27 of the application roller 16. It can preferably be provided that the application roller 16 has a convex curvature adapted to the concave curvature of the glass pane 11 (cf., for example, FIG. The adhering to the applicator roller 16 plastic film 12 is thus already adapted in the feed step to the curvature of the glass sheet 11.

At the same time in the feeding step, that is, during transport of the plastic film 12 on the application roller 16 to the joining position, the protective film 15 is peeled off and so the adhesive layer 13 of the plastic film 12 is activated. This is done in detail by that the plastic film 12 transferred onto the application roller 16 is held in firm contact with the casing 27 by the vacuum device 26, whereas the at least one adhesive tape 20 of the receiving device 35 simultaneously with the protective film

15 remains in adhesive contact. The fact that the at least one adhesive tape 20 is transported by the winding roller 36 in a direction different from the transport direction of the plastic film 12, the protective film 15 follows the adhesive tape 20 and is wound together with the adhesive tape 20 on the take-up reel 36. In order to support the removal process of the protective film 15 of the plastic film 12, the already mentioned deflection edge 43 is provided, via which the at least one adhesive tape 20 is guided. At this deflection edge 43, the actual stripping process of the protective film 15 takes place.

Due to this operative relationship, in the present embodiment, the receiving device 35 simultaneously constitutes a withdrawal unit 19 for removing the protective film 15 from the plastic film 12. The plastic film 12 resting on the application roller 16 with its exposed - and therefore activated - adhesive layer 13 is replaced by further rotation of the application roller 16 brought to a joining position, meet on the glass sheet 11 and plastic film 12 to each other and are connected in a controlled manner, namely by a rolling process under a defined pressure. This is done in detail as follows: The holding device 14 with the glass pane 11 is brought to the application roller 16, that a front edge 31 of the glass pane 11 is pressed against a front edge 32 of the plastic film 12 and thus an initially selective or only partially adhesive bond between Glass sheet 11 and plastic film 12 is created. Starting from this first adhesive bond (initial connection), the plastic film 12 is rolled onto the glass pane 11 by means of the application roller 16, possibly with the holding device 14, whereby due to the already given first adhesive bond, certain tensile forces can also be exerted for the smoothest possible application of the plastic film 12 , By the jacket 27 preferably formed of elastomeric material of the application roller

16, the applicator roller on the one hand sufficiently elastic and on the other hand can also apply a desired for the realization of the adhesive bond between the glass sheet 11 and plastic film 12 pressure.

If the processing of strongly different curved glass panes is desired, the application roller 16 could also be designed with an exchangeable casing 27 such that a casing 27 of a certain curvature is exchanged for a casing with deviating, for example stronger or less strong curvature. It can further be provided that the supply roll 37, as soon as the adhesive tape 20 provided by it is used up, is replaced by a new supply roll by an automatic exchange device for a new supply roll with new adhesive tape. Likewise, an automatic exchange device for removing a loaded with used tape 20 and peeled off protective films 15 take-up reel 36 may be provided against an empty take-up roll. The formation of the replacement devices as automatic replacement devices has the advantage that entries of dirt, such as dust, etc. are minimized by the change of the supply rolls or take-up rolls.

After the glass / plastic composite has been produced, the holding device 14 is returned to the rest position on a second transport path different from the first transport path from the rest position to the application roller 16. In the present arrangement, the holding device 14 would be lowered and spent on a relative to the first transport path below transport path to the rest position.

FIG. 4 illustrates a modified embodiment of a device for producing a glass / plastic composite according to the invention. The holding device 14, the recorded in the cassette 18 film stack 17 and the receiving device 35 and withdrawal unit 19 is in accordance with the imple mentation form of FIG. 3 is formed. Deviating, however, the film feed unit 21 is configured. Instead of a single conveyor roller, which simultaneously represents the application roller, here a plurality of conveyor rollers 22 to 25, 16, specifically five conveyor rollers are provided, wherein the last conveyor roller simultaneously represents the applicator roller 16. The conveying rollers 22 to 25, 16 are each in fluid communication with openings 26 provided in their sheaths 27, so that the vacuum device 26 causes a plastic film 12 transported by the film feeding unit 21 to engage the conveying rollers 22 until 25, 16 is held.

According to a particular aspect of the embodiment shown here, the curvature of the conveyor rollers 22 to 25, 16 gradually increase in the transport direction such that within the supply of the plastic film 12 to the joining position, the curvature of the plastic film 12 more and more to the curvature of the glass pane. 1 1 is adjusted. In this case, the conveying rollers 22 to 25, 16 may each be formed with a jacket 27 of a predetermined curvature in the manner of a bomb roller (see FIG. Alternatively and in the present embodiment, the curvature of the conveyor rollers 22 to 25, 16 can be set via a curvature setting device 49, specifically via pressure pistons 47 provided with rollers 46, which are accommodated in pressure cylinders 48 (see FIG. Although such a curvature adjusting device 49 is shown in FIG. 4 only for the last conveying roller, specifically the application roller 16, it is expediently also provided on the conveying rollers 22 to 25 previously arranged in the conveying direction in order to curve the conveying rollers 22 to 25 so that the curvature gradually increases from the first conveying roller 22 to the applying roller 16.

By means of the curvature setting device 49, it is possible to adjust the film feed unit 21 precisely to a specific shape of a glass pane 11. If glass panes 11 of greatly different curvature are processed, it is also possible to operate the device with a plurality of different holding devices 14, which differ in terms of the curvature of the positioning surface 30. About the curvature adjustment 49 can now either only the last conveyor roller, namely the applicator roller 16, are adapted to the respective predetermined curvature of the glass sheet 11 to be processed. Alternatively or additionally, however, it is also possible to change already upstream conveying rollers 22 to 25 via the curvature setting device 49 in its curvature.

Finally, the curvature setting device 49 can also cooperate with a controller in such a way that the curvature of the application roller 16 is changed within the joining step, for example in order to follow a curvature of the glass pane 11 which changes in the joining direction. Since the plastic film 12 within the film feed unit 21 can not lay itself on the provided in the 3rd quadrant conveyor rollers 25 and the applicator roller 16, it is necessary to use gravity. For this purpose, the film feed unit 21 is pivoted by about 90 ° in the clockwise direction via a pivoting device 53 together with the trigger unit 19. The pivoting against the transport direction of the plastic film 12 can be carried out continuously with the transport of the plastic film 12 until the plastic film 12 covers the pressure roller 16 on the outside. The holding device 14 in this case leads the glass pane 11 in a substantially vertical orientation.

FIG. 5 illustrates a third possible embodiment of a device according to the invention. Again, the components correspond to holding device 14, cassette 18 with film stack 17 and receiving device 35 or withdrawal unit 19 the already described with reference to the apparatus of FIGS. 3 and 4 corresponding components. However, the film feed unit 21 is again formed in a modified form and comprises a circulating conveyor belt 28 which defines a vacuum chamber 50 in a gastight manner together with two side walls provided on opposite sides. The circulating conveyor belt 28 is guided on a plurality of conveyor rollers 22 'to 25', 16 'and a tightening roller 40. The tightening roller 40 is arranged relative to the conveyor rollers 22 'to 25', 16 ', preferably substantially opposite one another. The vacuum chamber 50 is in fluid communication with a vacuum device 26 ', so that in the vacuum chamber 50 relative to the outside of the conveyor belt 28, a negative pressure is generated. In the conveyor belt 28, a plurality of openings 51 are provided so that a resting on the conveyor belt 28 plastic film 12 is held by the pressure prevailing in the vacuum chamber 50 vacuum in contact with the conveyor belt 28. About the receiving device 35 in the film stack 17 to uppermost lying plastic film 12 is transferred to the conveyor belt 28 and withdrawn by means of the trigger unit 19 during further transport of the plastic film 12 on the conveyor belt 28, the protective film 15 and so activates the adhesive layer 13.

The on the conveyor rollers 22 'to 25', 16 'guided conveyor belt 28 then transports the plastic film 12 to a joining position in which the plastic film 12 with the glass sheet 11 by a corresponding movement of the holding device 14 and possibly entrain the holding device 14 in itself already been combined manner. For pressing the plastic film 12 is also used in the present embodiment, the application roller 16 through which the conveyor belt 28 is guided so that the application roller 16 'here not directly hangs on the plastic film 12, but on the intermediate conveyor belt 28, the plastic film 12th pressed on the glass sheet 11.

Also in the embodiment according to FIG. 5 it is provided that the conveyor rollers 22 'to 25', 16 'have a gradually increasing curvature, specifically namely a deflection to the outside. Again, the application roller 16 'can be changed in its curvature by the Krümmungseinstelleinrichtung 49, for example, to adapt the device to glass panes of different curvature or to change over the joining step, the curvature when applying the plastic film 12 to the glass pane 11. In Fig. 6, a further modified imple mentation form for receiving device 35 and withdrawal unit 19 is shown, which is alternatively laminated with an arrangement according to FIG. 7, in which the plastic film 12 by means of an application roller 16 on the glass sheet 11 or with an imple mentation Shape of FIG. 8, in which the plastic film 12 can be laminated by means of a squeegee 54 on the glass sheet 11, are combined. In the arrangement according to FIG. 6, the plastic film 12 is removed from the receiving device 35 from the cassette 18 and transferred to a conveyor belt 58. The conveyor belt 58 transports the plastic film 12 to a cleaning unit 55, which is traversed by the plastic film 12. The cleaning unit 55 operates on the principle of the contact cleaning method, wherein the plastic film between two elastomer rollers 56, 57 in the machine direction is further moved.

After passing through the cleaning unit 55, the plastic film is transferred to a conveyor belt 28 which cooperates with a vacuum device 26 '. Via openings 51 in the conveyor belt 28, the plastic film 12 is held in abutment on the conveyor belt 28 so as to ensure by means of the withdrawal unit 19 already described in the withdrawal of the protective film 15 at the end of the conveyor belt 28. For this purpose, the trigger unit 19 is lowered onto the protective film 15 and pulls in a conventional manner, the protective film from the plastic film to be bonded 12, in which case on a table or carriage (not shown) arranged conveyor belt 28 in the stopped position under the trigger unit 19th is moved in the transport direction of the plastic film 12 therethrough.

After deduction of the protective film 15, the table or cart is in such a position that the leading edge of the plastic film 12 is present on the application roller 16 (FIG. 7) or on the applicator blade 54 (FIG. 8). The application roller 16 is provided with openings 45 for sucking the plastic film 12 by means of negative pressure. If an applicator blade 54 (FIG. 8) is used instead of the application roller 16 (FIG. 7), it is provided laterally at its tip with suction holes (not shown). When film recording the applicator blade 54 is tilted accordingly, so that arranged in a row suction holes can suck the plastic film 12. For film transfer, the conveyor belt moves over the stationary table or carriage in such a way that the start of film is pushed over the application roller 16 (FIG. 7) or the application blade 54 (FIG. 8) and from the application roller 16 (FIG ) or by the applicator blade 54 (FIG. 8) can be sucked. Then the table or cart returns to the starting position for receiving a new plastic film. For this purpose, the conveyor belt 28 is ventilated, so that the overlying film can be stripped off. To avoid scratches in the film surface, it makes sense if the conveyor belt 28 moves with the plastic film 12.

The plastic film falls onto a foil tray 59, which in a specific embodiment can also be designed as a segmented vacuum table and / or can also be curved in accordance with the requirements.

Alternatively, it is also conceivable to use a further vacuum belt, which has openings for sucking or holding the plastic film 12 by means of negative pressure only in the region facing away from the application roller 16 or the application blade 54. The vacuum belt is moved during the lamination process with the plastic film, so that thereby a tightening of the plastic film 12 is made possible. In another embodiment, the area of the film support surface remote from the application roller 16 is designed as a carriage. If the rear part of the plastic film 12 is located on the surface of the carriage, the plastic film 12 is sucked through holes in the support surface by negative pressure. During the lamination process, first the part of the support surface which is located between the application roller 16 and the carriage is moved downwards. The plastic film is stretched by the weight of the car.

In the lamination process, the carriage which is slidably mounted on rails is pulled upwardly by the pull of the plastic film 12 to the application roller 16 (Fig. 7) or to the applicator blade 54 (Fig. 8). In addition, it is noted that the applicator blade 54, after the plastic film 12 is glued to the glass sheet 11 in a first approach, is tilted after the start of lamination so that the holes in the side surfaces no longer suck the plastic film 12 and the negative pressure is switched off. Only when the car touches the upper limit switch, it is vented and thereby releases the plastic film. The car is then returned to its original position.

The glass pane 11 is moved in a manner already described above by the holding device 14 from a glass pane supply device to the joining position, for which purpose the holding device 14 is lowered onto the provided glass pane 11 and receives the glass pane with vacuum cups. The holding device 14 then moves with the glass pane picked up in the direction of the joining position, here essentially opposite to the film transport direction. Then put the glass

11 on the application roller 16 (FIG. 7) or the applicator blade 54 (FIG. 8) with the plastic film 12 on the glass pane 11 and the holding device 14 moves in the direction of film transport while under contact pressure of the revolving and curving application roller 16 (FIG ) or the curvilinear segmented application squeegee 54 (FIGS. 8, 9), the plastic film 12 is laminated onto the glass pane 11.

The lamination process is supported either by utilization of the film weight or by the vacuum segments of the film tray, so that only at the contact line of the application roller 16 and the applicator blade 54, an adhesive contact between the plastic film 12 and glass 11 comes about.

In Fig. 10, a further modified embodiment is shown, wherein construction and operation of the receiving device 35 and withdrawal unit 19 is formed according to the previous embodiments. Here, too, a plastic film 12 above is removed from the film stack 17 via the receiving device 35 and transferred to a film feed unit 21, the protective film 15 being simultaneously removed during further transport of the plastic film 12 in the film feed unit 21 and thus activating the adhesive layer 13 of the plastic film 12 becomes.

The film feed unit here comprises a plurality of conveyor rollers 22 to 25, 16, which are arranged substantially along a horizontal plane. Again, the conveying roller 22, as described above, with a vacuum device 26 cooperates such that via openings 45 in the shell 27 of the conveying roller 22, the plastic film

12 is held in contact with the feed roller 22. In order to ensure further transport of the plastic film 12 in the film feed unit 21, the plastic film 12 must be lowered onto the film feed unit 21 in such a way that it rests on the feed roller 23.

By means of a curvature adjuster 49, the curvature of each conveyor roller 22 to 25, 16 can be adjusted individually (shown in FIG. 10 only for the application roller 16). As already described, the curvature of each individual conveying roller 22 to 25, 16 can be adjusted via the curvature setting device 49 such that the curvature in the conveying direction of the plastic film gradually increases, so that the curvature of the application roller 16 to the curvature of the guided from the holding device 14 glass 11 is adjusted. The cradle needs the film like this Lower that it rests on the roller 23, so that it is transported by the rollers.

In the present embodiment, the structure of the holding device 14 corresponds to the structure explained with reference to FIG. 2. Notwithstanding the above-described embodiments, the holding device 14 in the present case, however, arranged above the film feed unit 21, that the intended for connection to the plastic film 12 concave inner surface of the glass sheet 11 directed downwards, or held in such a position to a through To avoid the foil own weight conditional premature sticking of the film by this is brought into adhesive contact only by the application roller with the glass pane. The glass sheet 11 is thus held by the suction openings 38 against gravity, wherein the frame 41 is arranged with the suction nozzle 42 above the glass pane 11.

The joining of down here plastic film 12 and top glass sheet 11 is done in the present embodiment substantially in an analogous manner as already described in the above imple mentation forms. First, glass sheet and plastic film are brought into contact with each other at their respective leading edges 31, 32 and then the plastic film 12 is rolled onto the glass sheet 11 by the application roller 16 and corresponding movement of the holding device 14. Subsequently, the glass / plastic composite produced in this way is dispensed on the side of the device facing away from the cassette 18, and the holding device 14 is returned to the rest position on a second path deviating from the first transport path, specifically above it.

Referring to FIGS. 11 and 12, a sixth embodiment of the device according to the invention will now be described, construction and operation of the receiving device 35 and the withdrawal unit 19 and the cassette 18 again corresponding to the previously described embodiments and therefore these components are not shown here. The in Fig. 11 on a conveyor roller 22 of the film feed unit

21 resting plastic film 12 has an already activated adhesive layer 13, that is, the protective film 15 has been removed by means of the withdrawal unit 19, not shown here. The device is shown in Fig. 11 in a position in which the glass sheet 11 already turned with its concave inner surface down from above to the conveyor roller

22 is brought in such a way that front edge 31 of the glass pane 11 and front edge 32 of the plastic film 12 to touch to form a first or initial, only partially adhesive bond. This process of training an inital bonding is fertil in another possible form of execution by provided on the conveyor roller 22 pressing means 33 is supported. Specifically, these pressing means 33 comprise a stretchable chamber 34 arranged between the roller core 44 and the jacket 27 made of elastomeric material, which can be filled with fluid, preferably air, for purposes of forming this initial adhesive connection so that the casing 27 of the conveying roller 28 moves locally bulges outward and the front edge 32 of the plastic film 12 is pressed to the glass pane 11. The pressing means is located in a cavity, which allows the leakage of the pressing means via a lens-shaped gap, wherein according to the lens shape in the middle of the contact pressure agent exits furthest.

Glass sheet 11 and plastic film 12, which are already connected to each other at their leading edges 31, 32 are now transported via the holding device 14 of the glass sheet 11 in the direction of an application roller 16 through which the actual joining step, namely the rolling of the plastic film 12 on the glass 11 is made. For this purpose, the application roller 16 is formed with a curvature adapted to the curvature of the glass sheet. This is achieved in the Vorhegenden embodiment concretely by the Krümmungseinstelleinrichtung 49, which acts in the manner already described above on the applicator roll such that there is a matching to the curvature of the concave inner surface of the glass sheet curvature.

After production of the first adhesive contact, the holding device 14 is thus moved past the conveyor roller 22 that initially no further adhesion can be achieved, but the plastic film is tightened under tension. Subsequently, the glass pane 11 touches the application roller 16, which is arranged laterally below the conveyor roller 22, at the location of the glued-on film area. By pressing and advancing the flexible cylindrical application roller 16, the plastic film 12 is continuously applied to the glass sheet 11 or laminated. Subsequently, the glass / plastic composite is dispensed and the holding device 14 is moved back to the rest position for recharging.

In Fig. 13 is a schematic sectional view through the conveying roller 22 comprising a roller core 44 and a jacket 27, which has the elastic chamber 34 at a certain position between the roller core 44 and shell 27 is shown. The expandable chamber 34 causes the jacket 27 made of elastomeric material can be arched first at a point in the middle and then subsequently in a line for the first sticking to the outside, so locally to the front edge 32 of the plastic film 12th an additional contact pressure can be exerted in order to create this first, initial adhesive bond between glass pane 11 and plastic film 12. The expandable chamber 34 may have a cushion shape or be formed as a closed tube, wherein the expandable chamber 34 is inflated to make the contact and emptied after the contact operation.

FIG. 14 shows a seventh embodiment with a further modified film feed unit 21. Cassette 18 with film stack 17, receiving device 35 or withdrawal unit 19 and holding device 14 are formed as already described above. Similar to the embodiment described with reference to FIG. 5, a circulating conveyor belt 28 is provided which, together with two side cheeks, encloses a vacuum chamber 50. The conveyor belt 28 is here essentially guided around a triangular path and runs correspondingly around three rollers, in this case specifically around a first conveyor roller 22 ', a second conveyor roller 23' and an application roller 16 '.

The plastic film 12 is transferred in the manner already described by the receiving device 35 on the conveyor belt 28, specifically in the region of the first conveyor roller 22 '. The protective film 15 is pulled off via the deflecting edge 43 via at least one adhesive tape 20 and wound onto the take-up reel 36 via the withdrawal unit 19, which is also already described. The plastic film 12 is held by suction on the conveyor belt 28, which is provided for this purpose with a plurality of openings 51 which communicate with the vacuum chamber 50 of the conveyor belt. The negative pressure in the vacuum chamber 50 is generated via the already mentioned vacuum device 26 '.

The resting on the conveyor belt 28 plastic film is transported over a first substantially horizontally extending portion on which also the already mentioned deduction of the protective film 15 is made. With open adhesive layer

13 passes the plastic film 12 to the second conveyor roller 23 'and is further transported by the conveyor belt 28 to a joining position, in which the plastic film 12 is connected via the applicator roller 16' with a guided from the holding device 14 glass pane 11. Specifically, this is done by the plastic film lying on top 12 is positioned and pressed with its front edge 32 to the front edge 31 of the glass sheet 11 and then by pressing the applicator roller 16 'with a downward force and carrying the holding device

14, if necessary, applying an upward force, the plastic film 12 is rolled or laminated to the glass. The application roller 16 'can be provided with a curvature adjusted by means of a curvature adjustment device 49 with a curvature adapted to the concave inner surface of the glass pane 11. Also, the feed rollers 22 'and 23' may be provided with a, but lower curvature, such that the plastic film 12 receives a curvature adapted to the curvature of the inner surface of the glass sheet 11 via the feeding step in the film feed unit 21. Due to the particularly easy adaptation of the application roller 16 'to a desired curvature, the device described here can be used very flexibly, for example for processing glass panes of different curvature.

FIGS. 15 to 17 show a further modified embodiment of a device according to the invention. The holding device 14 is designed as explained with reference to FIG. 2. However, the receiving device 35 or withdrawal unit 19 is slightly modified, namely to the effect that the deflection roller 39 provided between the supply roll 37 and the take-up roll 39 can be forced by means of a curvature adjustment device 49 to make a bend. Specifically, this is done according to the principle illustrated with reference to FIG. 14. The curvature setting device 49 comprises namely a plurality, for example three or four pressure cylinders 48, in each of which pressure piston 47 is mounted and can be acted upon by a pressure piston 47 out of the pressure cylinder 48 out moving force. At the distal ends of the pressure piston 47, a plurality of rollers 46 are provided, which may be formed for example as pairs of rollers and on the corresponding roller, here specifically the deflection roller 39 act in such a way that a defined curvature applied to this roller or roller becomes.

The operation of the device according to FIGS. 15 to 17 will be explained below. The receiving device 35 removes the plastic film 12 above from the film stack 17 in that one or more adhesive tapes 20 contact the plastic film 12 on its protective film 15. The receiving device 35 then transfers the removed plastic film 12 onto the application roller 16 so that the receiving device 35 with the deflection roller 39 descends onto the application roller 16. The application roller 16 cooperates with a vacuum device 26 in the manner already described in such a way that the plastic film 12 adheres to the shell 27 of the application roller 16. In this way, in the present embodiment, the application roller 16 itself, the film supply unit 21 represent, so in cooperation with the trigger unit 19 during further transport of the plastic film 12 and a removal of the protective film 15 of the plastic film 12 effect. The leading edge 32 of the plastic film 12 is brought into a joining position at a position offset by 180 °, ie opposite position, in relation to the deflecting roller 39 arranged at the top, in which (see Fig. 17) a front edge of the glass pane 11 with its front edge 31 in FIG Alignment is brought, so that starting from this positioning by pressing the applicator roller 16 on the glass sheet 11 or with the support of the holding device 14, a first adhesive contact and then rolling or laminating the plastic film 12 can be made on the glass 11.

The application roller 16 may be provided with a predetermined outer curvature in the manner of the application roller illustrated with reference to FIG. 19. However, in the present embodiment, a desired curvature of the application roller 16 at the joining position is generated by the deflecting roller 39 disposed on the opposite side, which itself can be curved by the curvature adjusting device 49. In this respect, the curvature of the application roller 16 is controlled by the curvature of the deflection roller 39. After lamination of the plastic film 12 to the glass pane 11, the holding device 14 is returned to the rest position for receiving a new glass pane on the basis of a second transport path.

In all of the embodiments described above, the surfaces of the applicator rollers or belts preferably consist of a special elastomer having a specific material thickness and material hardness in order to achieve an optically distortion-free and smooth plastic film surface on the glass / plastic composite.

The embodiment described here has a relatively simple construction and can moreover be adjusted flexibly to different curvatures of the glass pane to be processed by means of the curvature setting device 49 acting on the deflection roller 39. LIST OF REFERENCE NUMBERS
