- a device which allows the production of plastic cards with high lamination quality at high production speeds is created according to the invention in that the pressing members are arranged so as to be movable in the direction of the conveying path against a restoring force effective on their starting position.
- the invention relates to a device according to the preamble of claim 1 for laminating a layer structure of at least two plastic belts with successive uses for the production of plastic cards along a conveyor line, comprising heating and cooling devices arranged in succession, each of which can be temperature-controlled and which receives an integer number of uses Press members are formed, which are arranged on a common carrier, and a drive unit, the mutually facing, intermittently drivable in a conveying direction press belts, between which the plastic belts can be moved in sections by the heating and cooling devices.
- EP-B-0 134 820 describes a device which allows for a continuous production of plastic cards, in particular credit cards, check cards, access cards, etc., a synchronous feed of plastic tapes into a laminating plant to form a laminate.
- the plastic straps consist of individual, separate benefits that are arranged in one or more rows one behind the other.
- the laminating system comprises heating and cooling devices made of temperature-controlled pressing members arranged on a longitudinal support, the dimensions of which are selected for the treatment of an integer number of uses in each case and allow the plastic strips forming a layer structure to be baked in sections with subsequent cooling.
- the at least two plastic belts are moved by arrangement between mutually facing, cyclically drivable, endless press belts in treatment zones for the pressing members, in which the heat-pressure action and the cooling-pressure action 2
- the pressing members each comprise a fixed lower and a movable upper pressing bar, between which the pressing belts come into contact during the heat / cooling-pressure treatment.
- DE-C-42 05 746 describes a device for gluing flat workpieces, in particular for laminating plate-shaped plastic parts, in which a placement station, a heating station, a pressing station and a cooling station arranged outside the pressing station are arranged one after the other.
- the workpieces to be glued are passed one after the other on a lower conveyor belt first through the heating station and then through a pair of press rolls of the press station.
- the press station defined by the pair of press rolls also serves as a deflecting roller for conveyor belts and cannot be moved relative to the conveyor line.
- the heating station comprises two heating plate units, each of which has a link chain made up of several chain links, on which crosswise to the 3
- Crossbeams with conveyors are mounted with radiators.
- the links of the link chain are connected on both sides to each other by means of intermediate links with a drive cylinder via a drive rod, the actuation of which enables the two link chains of the heating plate units to be parallel to one another, substantially bulged in the same direction, or to be designed in a wedge-shaped manner.
- the limbs of the heating plate unit are adjustable, but this setting does not allow a movable arrangement of the heating element or even the pressing station or the movement in the direction of the conveying path due to the static, sufficiently fixed position of the drive cylinder.
- a cooling press is not provided.
- the position of the chain links is static.
- the device according to the invention advantageously decouples adjacent pressing members, so that the pressing members can have a slight change in distance from one another in the conveying direction. This makes it possible to position the clocked or intermittently driven press belts and the plastic belts lying against them, which are exposed to different temperatures due to the different temperature of the press members, precisely in the press members. The stresses which otherwise act on the press belts or plastic belts are thereby greatly reduced.
- a lifting device which raises the upper press beam can be actuated for wide opening of the press members, the opening movement of the upper press beam being small in normal operation in order to enable the press belts to be advanced.
- a lifting device is provided which, in the event of a production stop, lifts the press belts at the same time in order to interrupt a contact bridge between the press belts and the lower press bars when the press member is opened.
- the press belts are shifted into an approximately centrally located position between the lower and the upper press beams. This prevents undesired overheating of the press belts, since the press belts then only serve as heat exchangers during the heat-pressure treatment. This significantly increases the service life of the press belts. In particular in the event of a malfunction or maintenance, overheating of the plastic straps is effectively prevented, which would otherwise result in extensive set-up work. 5
- the press belts are expediently placed over an inlet drum arranged outside the press members and an outlet drum.
- At least one of the drums has a circumferential precision spike section which is in drive connection with a transport perforation provided in an edge zone of an associated press belt.
- the spiked section enables exact adjustment and slip-free guidance of the press belt.
- the height of the spike is approx. 0.5 mm.
- the spines were rounded at the top.
- Each of the drums is preferably provided with a spike section, the inlet drums and the outlet drums being offset from one another in order to prevent the spikes from hitting one another.
- the offset of the drums in the inlet area and in the outlet area is preferably identical and in the same direction, so that an identical belt can be used for both press belts.
- Fig. 1 shows schematically a side view of a first
- FIG. 2 shows schematically a side view of the device
- FIG. 1 shows schematically a partial side view of a second
- the plastic tapes forming the layer structure 1 are fed in synchronously, the various plastic tapes to be laminated to a laminate having previously passed through different processing stations in which the panels can have been provided with synchronization holes and with printed images, information carriers, die cuts, etc., in order to produce the sheets To equip plastic cards for the intended purpose.
- the average thickness of the plastic strips to be processed is preferably approximately 0.1 to 3 mm, depending on how many plastic strips form a layer structure 1.
- the total thickness of the finished plastic cards is usually around 0.8 mm.
- four plastic tapes are brought together to form a layer structure 1, namely a top and bottom transparent film tape and two middle printed tape strips.
- the press belts 2, 3 are formed by two self-contained, mutually facing, endless belts, each of which is placed over an inlet drum 4, 5 and an outlet drum 6, 7. At least one of the belts, for example the lower belt, is driven step by step and takes the layer structure 1 and the other belt with it when it rotates, provided that these are not driven synchronously.
- the press belts 2, 3 In its outer edges, the press belts 2, 3 have a continuous transport perforation, which meshes with a spike section of the four drums 4, 5, 6, 7 and defines a unique, mutually unchangeable position. So that the press belts 2, 3 work as slip-free drivers for the layer structure 1, facilities for register-based transport are in 7
- Such devices are in the present case provided on at least one press belt pins which engage in aligned register holes of the layer structure 1 and the other press belt.
- adhesive devices can also be used.
- the position of the layer structure 1 between the press belts 2, 3 is thereby determined.
- a drive of the press belt provided with the pins and the transport perforation leads to precise positions of the layer structure 1 in the heating devices and cooling devices described below.
- the surface of the press belts 2, 3 facing the layer structure shapes the surface of the layer structure.
- Heating devices 8, 9 and cooling devices 10, 11 are arranged in succession along the press belts 2, 3 and are formed by individual temperature-controlled pressing members. The number of heating devices 8, 9 and cooling devices 10, 11 arranged side by side can be selected. The heating devices 8, 9 and the cooling devices 10, 11 are each arranged at a distance from one another, their spacing following the spacing of the benefits of the layer structure 1, so that the heating and cooling devices 8, 9, 10, 11 each act on an integer number of benefits.
- the heating devices 8, 9 and cooling devices 10, 11 are designed as pressing members, each with an upper pressing bar 12 and a lower pressing bar 13. Between the upper press beam 12 and the lower press beam 13 of a number of press members, the layer structure 1, guided between the two press belts 2, 3, runs in a conveying direction which runs from right to left in FIGS. 1 and 2.
- the pressing members designed as heating devices 8, 9 can be heated electrically or by means of a temperature-regulating fluid, while the pressing members designed as cooling devices 10, 11 are preferably water-cooled. Alternatively, it is possible to provide each of the heating devices 8, 9 and cooling devices 10, 11 with its own upper and lower stamp. 8th
- Fig. 1 shows the two press beams 12, 13 in a closed position of the pressing members for a temperature-controlled pressure treatment of the layer structure 1, at least the upper press beam 12 being movable in the manner of a stamp in order to exert a compressive force on the lower press beam 13.
- the pressing members are opened by slightly lifting the respective upper pressing beam 12 and the pressing belts 2, 3 with the layer structure 1 treated in sections are moved further in the conveying direction, for example the section of the layer structure 1 treated in the heating devices 8, 9 in the area of Cooling devices 10, 11 moves.
- the upper press beam In normal operation, the upper press beam is raised a little, the press belts are moved, and the upper press beam is lowered again in order to transfer the temperature.
- the wide opening of the upper press beam 12 is recognized by a control device 30, in particular caused and determined by this, which actuates a lifting device 31, 32 in order to press the press belts 2, 3 which come into contact between the press beams 12, 13. to be lifted off the lower press beams 13 when the press members open wide.
- the lifting device 31, 32 is formed here by the elevators arranged on the input and output sides of the heating and cooling devices 8, 9, 10, 11, which can be moved upwards relative to an disengaged position with respect to the press belts 2, 3, as in FIG Fig. 2 shown.
- the press belts 2, 3 extending between the press bars 12, 13 of the press members are hereby clearly along the treatment zone defined by the heating and cooling devices out of contact with the lower press bars 13 and preferably in a raised central position between the two press bars when the upper one Press beam 12 opens wide or has opened wide.
- the distance between the press belts 2, 3 to the lower and / or to the upper press beam 13, 12 is preferably between 1 cm and 35 cm.
- other lifting devices for example a compressed air supply, can be provided.
- the individual pressing members can be individually adjusted with regard to their temperature and the pressure they exert, the layer structure 1 remaining between the presses for the heating and cooling process. Temperature and pressure are chosen such that the baked and cooled layer structure 1 forms a stable laminate. For a gradual advance of the layer structure 1, the presses are each opened slightly. Then the section of the layer structure 1, which has been treated by the heating devices 8, 9, is moved with a cyclical feed into the treatment area of the cooling devices 10, 11, so that the layer structure 1 preferably undergoes a heating and cooling process in sections. The duration of the heating and cooling processes determines the cycle times.
- the heating devices 8, 9 and cooling devices 10, 11 are arranged on a common carrier 14, which sets up the individual pressing members of the heating devices 8, 9 and the cooling devices 10, 11 axially displaceably against one another against a restoring force.
- the lower press beams 13 are arranged on the carrier 14.
- the carrier 14 is designed as a straight longitudinal beam, which is supported at both ends by supports 15, 16 and predetermined bending points 17, 18, 19 between two successive pressing members of the heating and cooling devices 8, 9, 10, 11 ,
- the predetermined bending points 17, 18, 19, which allow local deflection or bending of the carrier 14, are formed by slots 21, 22, 23 extending in the direction of a longitudinal beam support surface 20, below which the carrier 14 resiliently rests on supports 24, 10
- the slots 21, 22, 23 partially cut the carrier 14 transversely to the longitudinal axis, the slot length in the direction of the support surface 20 determining the bending dimension. It is essential here that the predetermined bending points 17, 18, 19 each lie between the individual heating and cooling devices 8, 9, 10.1 1 transversely to the longitudinal axis, and as centrally as possible between them, in order to follow expansions and shrinkages of the press belts 2, 3 to be able to relieve them.
- Heating and cooling devices 8, 9, 10, 11 cause a local upward or deflection of the carrier 14 in this assigned area, whereby the
- This load builds up a restoring force which follows from the remaining rigidity of the carrier 14 left by the slots 21, 22, 23 and the resilient supports 24, 25, 26.
- the constructively effected compensation of a temporary bending or bending caused by the press belts 2, 3 can be carried out individually, i.e. the various predetermined bending points can be loaded differently.
- Fig. 3 shows a second embodiment of an apparatus for laminating a layer structure 1 in sections from at least two plastic belts with successively formed uses for the production of plastic cards along a conveyor line, which differs from the first embodiment described above in that the individual pressing members can be axially displaced relative to one another counter to a restoring force, the successive pressing members of the heating and cooling devices 8, 9, 10, 11 are arranged axially displaceably relative to one another via roller bearings 40, 41 relative to the longitudinal beam 14.
- the pressing members are supported in the direction of conveyance between the two axial ones 1 1
