Through the EP 2 095 945 A1 a device for the lateral alignment of workpieces is disclosed.

The invention has for its object to provide a lamination machine.

The object is achieved according to the invention by the features of claim 1.

One advantage is, in particular, that sections can be separated from a material web in a particularly simple, precise and rapid manner without waste being produced during ongoing operation which would increase the risk of malfunctioning the processing machine. The precision is preferably supported by two clamping devices and possibly a single alignment of sheets.

One advantage is, for example, that a particularly fast and trouble-free lamination operation is made possible. This is achieved, for example, by web-shaped lamination material and more preferably by means of a roll changer for the Unwind the lamination fabric. In particular, the start of a lamination operation is simplified if a disposal device for lamination material is arranged, for example because in this way production can be started quickly and easily without removing the lamination material by hand from areas that are difficult to access.

One advantage is, for example, that a particularly high level of precision can be achieved when applying the lamination material. This is achieved, for example, by means of web edge aligners and / or web tension control when the lamination material is fed in. Alternatively or in addition, sheets to be laminated are aligned particularly precisely, for example by separating and / or aligning the sheets and / or arranging the sheets in a shingled manner with respect to one another.

One advantage is, for example, that sheets can be laminated particularly precisely and that the sheets or the sections are not damaged during the process, for example by attacking knives or incomplete lamination.

There is an advantage, for example, if at least one lamination control device is arranged, because a proper lamination of sheets and production of a material web can then be monitored. If an error is detected, a quick response can be made, for example by stopping the cutting device and / or the lamination machine. In this way, waste can be avoided and the risk of damage to the separating device and / or the lamination machine can be reduced.

There is an advantage, for example, if at least one separating sensor device is arranged because a reaction can then be made in the event of an incorrect separation of a section from a material web, for example by stopping the separating device and / or the lamination machine. In this way, waste can be avoided and the risk of damage to the separating device and / or the lamination machine can be reduced.

There is an advantage, for example, if at least one drawing-in means for lamination material is arranged. The lamination machine can then be made ready for use particularly quickly and precisely, for example after a restart or after a brief interruption in production. This makes handling easier, especially when the material is laminated on both sides.

There is an advantage, for example, if at least one thickness control device is arranged in order to monitor the transport path of the material web. Then scaling can take place in a controlled manner and / or separation can be carried out particularly precisely and / or errors which could be caused by connecting points of webs of lamination material can be avoided. Overall, this results in an increased production quality and a lower susceptibility to errors.

The expansion cylinder preferably has 453 and / or the first clamping cylinder 456 and / or the second clamping cylinder 458 each have a jacket surface made of a relatively soft material, for example rubber.

Regardless of whether the at least one separating device 400 is formed in the first or the second embodiment, it preferably allows a method for separating at least one section 04 from a web of material 02 . For example, bows first 03 from a pile of sheets 102 removed and isolated, in particular to the extent that each sheet 03 to its directly adjacent arch 03 has a distance. Then the separated sheets 03 preferably individually aligned. After that, the aligned arches 03 preferably brought into a scaled position relative to one another. In particular will be followed by a subsequent sheet 03 partly under a leading arch 03 placed. This arrangement is called undercutting. Thereafter, the sheets are arranged in a shingled manner, but in particular are nevertheless relatively independent of one another 03 by means of at least one lamination substance 321 ; 331 to a web of material 02 connected. The material web 02 is, in particular regardless of its origin, preferably in at least one front clamping point 401 at least one front clamping device 406 clamped and in at least one rear clamping point 402 at least one rear clamping device 404 clamped. A transport line is preferably a shortest component of the separating device that lies completely in a vertical reference plane 400 on the same side as the material web 02 and / or the at least one section 04 Passing or tangential connection between the at least one front clamping point 401 on the one hand and the at least one rear clamping point 402 on the other hand. At least a first expansion element 403 is moved from a first passing layer into a first separating layer and thereby the transport line is stretched so far that the at least one section 04 from the material web 02 rips off. In particular, the at least one section tears 04 from the material web 02 off by the at least one lamination material 321 ; 331 rips.

The web of material preferably tears 02 at a respective intended separation point. Preference is given to the severed section after the tearing 04 initially at the rear clamping point 402 clamped and can therefore by the rear clamping device 402 can be continued and transported. The material web is preferred after the tearing 02 at least initially at the front clamping point 401 clamped and can therefore by the front clamping device 401 can be continued and transported.

In particular, the movement of the at least one first expansion element takes place 403 from the first passing layer into the first separating layer during the material web 02 and possibly already separated sections 04 be transported forward along the transport route. A transport of the material web 02 and the severed sections 04 so does not need to be interrupted. This is preferably made possible by the fact that the clamping points 401 ; 402 are formed by rotating components.

In the following, part of a method is first described in which the first embodiment of the separating device 400 is used. First is the web of material 02 both at the front clamping point 401 as well as at the rear clamping point 402 clamped and becomes due to the rotation of the front draw roller 408 around their axis of rotation 422 and the front pressure roller 407 around their axis of rotation 421 and the rear pull roller 411 around their axis of rotation 424 and the rear pressure roller 409 around their axis of rotation 423 nevertheless through both clamping points 401 ; 402 transported. During the transport of the material web 02 becomes the at least one second expansion element 412 around its second axis of elongation 416 pivoted and thereby brought into a spatial area that was previously the material web 02 occupies. The at least one second expansion element 412 thus rises above one of the conveyor belts, for example 431 educated level. As a result, the transport line is deflected, in particular raised, and thereby stretched or lengthened. A direction of rotation of the at least one second expansion element is preferred 412 chosen so that the at least one second expansion element 412 in the layers, in particular separating layers, in which it extends the transport line, has a movement component that is parallel to a transport direction of the material web 02 runs. This preferably results in as little relative movement as possible between the material web 02 and the at least one second expansion element 412 . Unintentional damage to the web of material 02 are thereby reduced or avoided. An angular range of movement of the at least one second expansion element 412 , in which the at least one second expansion element 412 at least partially over the conveyor belts 431 formed plane protrudes is preferably at least 100 ° and more preferably at least 120 ° and preferably at most 150 ° and more preferably at most 130 °.

Also during the transport of the material web 02 will the at least one third expansion element 413 around its third axis of elongation 417 pivoted and thereby brought into a spatial area that was previously the material web 02 occupies. The at least one third expansion element 413 rises above the conveyor belts, for example 431 educated level. As a result, the transport line is deflected, in particular raised, and thereby stretched or lengthened. A direction of rotation of the at least one third expansion element is preferred 413 chosen so that the at least one third expansion element 413 in the layers, in particular separating layers, in which it extends the transport line, has a movement component that is parallel to a transport direction of the material web 02 runs. This preferably results in as little relative movement as possible between the material web 02 and the at least one third expansion element 413 . Unintentional damage to the web of material 02 are thereby reduced or avoided. An angular range of movement of the at least one third expansion element 413 , in which the at least one third expansion element 413 at least partially over the conveyor belts 431 formed plane protrudes is preferably at least 100 ° and more preferably at least 120 ° and preferably at most 150 ° and more preferably at most 130 °.

Also during the transport of the material web 02 becomes the at least one first expansion element 403 around its first axis of elongation 414 pivoted and thereby at least partially brought into a spatial area, which at this time between parts of the at least one second expansion element 412 and dividing the at least one third expansion element 413 is arranged. The at least one first expansion element 403 as a result, for example, is lowered between the at least one second expansion element 412 and the at least one third expansion element 413 .

As a result, the transport line is lengthened further, in particular in that it is prevented from lifting and / or lowered in this area, and thereby stretched or lengthened. A direction of rotation of the at least one first expansion element is preferred 403 chosen so that the at least one first expansion element 403 in the layers, in particular separating layers, in which it extends the transport line, has a movement component that is parallel to a transport direction of the material web 02 runs. This preferably results in as little relative movement as possible between the material web 02 and the at least one first expansion element 403 . Unintentional damage to the web of material 02 are thereby reduced or avoided. The method is then preferably characterized in that at least one second expansion element is used to stretch the transport line 412 is moved from a second passing layer into a second separating layer and / or at least a third expansion element 413 is moved from a third passing layer to a third separating layer and the transport line gets at least one additional turning point with regard to its curvature, in particular as a result. A turning point is in particular a point at which a curvature changes its direction and / or its leading.

By extending the transport line, the section 04 from the material web 02 Cut. The predetermined separation point is preferably located with respect to the transport path of the material web 02 in the area of the at least one first expansion element 403 . The severed section 04 is by the rear clamping device 404 transported further. The leading end of the web of material 02 is preferably located at the latest after a further movement of the expansion elements 403 ; 412 ; 413 on the conveyor belts 431 on and is from these in the rear clamping device 404 directed. Then the cycle starts again. While the expansion elements 403 ; 412 ; 413 are arranged in their respective passage layers, they are preferably out of contact with the material web 02 . Especially because of the preferred by the drives of the clamping devices 404 ; 406 independent drive of the expansion elements 403 ; 412 ; 413 these can now be operated at increased or reduced speed and then accelerated in the opposite direction again. This allows the separating device 400 to different lengths between intended separation points and thus to different lengths of the arches 03 and / or sections 04 be adjusted.

As an alternative or in addition, the method is preferably characterized in that the at least one first expansion element 403 and / or the at least one second expansion element 412 and / or the at least one third expansion element 413 independent of the front clamping device 406 and / or independently of the rear clamping device 404 and / or is driven with an in particular respective periodically fluctuating angular velocity. As a result, on the one hand, an adaptation to different section lengths, that is to say different nominal lengths of the sections 03 , respectively. On the other hand, this can result in a relative speed between the material web 02 on the one hand and the first expansion element 403 and / or second expansion element 412 and / or third expansion element 413 on the other hand, are kept as low as possible, especially although the speed of the respective expansion element 403 ; 412 ; 413 because of its rotation most of the time in a component parallel to the transport direction of the material web 02 and divides a component orthogonal thereto.

As an alternative or in addition, the method is preferably characterized in that an angular velocity of the at least one second expansion element 412 during its contact with the material web 02 is initially reduced and then increased again and / or at a distance from the material web 02 is driven with an angular speed varying as a function of a provided section length and / or that an angular speed of the at least one third expansion element 413 during its contact with the material web 02 is initially reduced and then increased again and / or at a distance from the material web 02 is driven with an angular velocity varying as a function of an intended section length. As an alternative or in addition, the method is preferably characterized in that an angular velocity of the at least one second expansion element 412 always with an angular velocity of the at least one third expansion element 413 matches.

The separator 400 for separating sections 04 from a web of material 02 , which, as described, preferably has at least one front clamping device 406 with at least one front clamping point 401 and at least one rear clamping device 404 with at least one rear clamping point 402 and at least one first expansion element 403 having, preferably by moving at least the at least one first expansion element 403 the separating device between at least one first passing layer and at least one first separating layer 400 can be switched between at least one passing state and at least one disconnecting state, or this disconnecting device 400 comprising lamination machine 01 preferably has at least one separation sensor device 463 on. In terms of circuitry, this at least one separation sensor device .463 is preferably connected to a machine control of the lamination machine 01 connected.

At least one separation sensor device is preferred 463 for detecting a respective gap between the material web 02 and the last separated section 04 arranged. By means of this separation sensor device 463 can thus be monitored whether a separation of a section 04 from the material web 02 was successful. The separation sensor device preferably measures 463 but directly in the area in which the separation takes place, i.e. in the area of the separating device 400 .

A measurement of a signal can then be aimed at, which can be determined at the moment of separation. For example, by overstretching and tearing off the section 04 from the material web 02 at least for a short time a small gap between the material web 02 on the one hand and the section that has just been separated 04 on the other hand generated. A signal can be transmitted through this gap, for example an electromagnetic signal, in particular a light signal. When the signal is transmitted, it is confirmed that the gap has existed at least for a short time, even if by a subsequent reduction of the transport line by movement of the expansion elements 403 ; 412 ; 413 the just created trailing end of the just severed section 04 again with a leading end of the web of material that has just been produced 02 overlaps and the signal interrupts again. The subsequent overlap represents the successful separation of the section 04 out of the question.

In particular, the at least one is preferred as a reflector 467 trained sensor element 467 together with the at least one first expansion element 403 movably arranged and / or stationary relative to the at least one first expansion element 403 arranged.

From the sending facility 466 Emitted electromagnetic radiation can then with a corresponding relative alignment of the reflector 467 reflected and onto the detector 464 be steered. However, this is only possible as long as neither the material web 02 still separate sections 04 interrupt the beam path.

The separating device is preferably distinguished 400 characterized in that at least and further preferably exclusively when the first expansion element is arranged in its separating layer 403 one from the transmitting device 466 outgoing beam path of electromagnetic radiation through a reflector 467 the separation sensor device 463 reflected and onto the detector 464 the separation sensor device 463 is directed. On the one hand, the beam path is through the material web 02 interrupted as long as a separation has not just taken place and / or is taking place. On the other hand, at least with a corresponding arrangement of the reflector 467 on the first expansion element 403 also a layer of this first expansion element 403 relevant because a reflection is only possible if the reflector 467 is just arranged aligned accordingly. A situation in which a reflection and thus a registration of a corresponding signal is possible is preferably only given if the first expansion element 403 is just arranged in its separating layer and the transport line is enlarged just enough that a section 04 from the material web 02 is torn off and the overlap is canceled at this point and a gap between the web of material 02 and section 04 originated. The first expansion element must also be used for this overstretching 403 preferably be arranged in its separating layer.

In regular operation, at least the first expansion element should then be used for each movement cycle 403 once a confirmation of a successful separation of a section 04 from the material web 02 respectively. This is preferably monitored by means of a machine control. If the expected signal is not received, there is an error, for example incomplete or missing separation. The response is, for example, the operation of the separating device 400 and / or the lamination machine 01 interrupted.

The following describes part of a method in which the second embodiment of the separating device 400 is used. The method is preferably characterized in that the at least one first expansion element 403 in its separating position assumes a position in which there is a straight connection between two of the first cylinder channel 452 delimiting channel edges is cut and thereby the transport line gets at least one additional turning point with regard to its curvature.

First, the material web runs 02 between the front clamping point 401 and the rear clamping point 402 . The front clamping point 401 is held by a front clamping device 406 set, in this case by the support cylinder 451 on the one hand and the at least one first clamping cylinder 456 and in particular its first terminal elevation 457 on the other hand is formed. The rear clamping point 402 is by a rear clamping device 404 set, in this case by the support cylinder 451 on the one hand and the at least one second clamping cylinder 458 and in particular its second terminal elevation 458 on the other hand is formed. By rotating the support cylinder 451 and the first clamping cylinder 456 and the second clamp cylinder 458 becomes the web of material 02 transported forward. With a corresponding rotational position of the at least one expansion cylinder 453 immersed the attached first expansion element 403 in the first cylinder channel 452 then the at least one expansion cylinder 453 opposite support cylinder 451 a. This results in the lengthening or stretching of the transport line and thus the tearing of the material web 02 analogous to the method by means of the first embodiment of the at least one separating device 400 .

The severed section 04 is from the rear clamping point 402 forwarded and sent to a facility 502 ; 503 that ensures its safe further transport, for example another terminal point 503 or a conveyor belt 502 or a suction belt 502 .

To make this possible, the circumference of the first clamping cylinder is preferred 456 so in the first terminal elevation 457 one hand and one to this lowered section 04 on the other hand split that the first clamping cylinder 456 temporarily out of contact with the support cylinder 451 equipment. Furthermore, the circumference of the second clamping cylinder is preferred 458 so in the second terminal elevation 459 on the one hand and a lowered section 04 on the other hand split that the second clamping cylinder 458 temporarily, in particular simultaneously with the first clamping cylinder 456 , out of contact with the support cylinder 451 equipment. The second cylinder channel 454 of the at least one expansion cylinder 453 is preferably also selected in its position and extent in the circumferential direction so that at the same time the at least one support cylinder 451 with the at least one expansion cylinder 453 gets out of contact. This allows the support cylinder 451 be rotated without the material web 02 to influence. Instead, the material web slides on the support cylinder during this time 451 instead of. The support cylinder 451 preferably has one opening or a plurality of openings for sucking in and / or ejecting gas, in particular air, for example around the material web arranged thereon 02 and / or the part of the corresponding section arranged thereon 04 to be able to hold on and / or loosen in a targeted manner.

Regardless of the embodiment of the at least one separating device 400 the separated sections are then transported again 04 , in particular by means of a corresponding device 502 , for example a conveyor belt 502 and / or a suction belt 502 . The sections are preferred 04 after the separator 400 brought at least briefly to an increased speed in order to achieve a separation of the sections.

As an alternative or in addition, the method is preferably characterized in that the at least one pull-in means is carried out in a connection process directly or more preferably by means of at least one connection element 347 with the at least one lamination material in web form 321 ; 331 is connected. This is preferably done before the passing process. The connection is made, for example, by hooking in and / or magnetically and / or by screwing and / or by closing a Velcro fastener.

As an alternative or in addition, the method is preferably characterized in that, after the drawing-in process, the material to be laminated 02 the at least one lamination plant 310 fed and there by connection with the at least one web-shaped lamination material 321 ; 331 is laminated. More preferably, the unwinding and joint pivoting and joining of the webs of the lamination materials then takes place 321 ; 331 as already described.

Preferably begins after the lamination material has been drawn in 321 ; 331 a transport of the material to be laminated 02 in the lamination plant 310 where a laminated sheet of material 02 is produced. That doesn't rule out the material 02 previously in another area of the processing machine 01 is moved, but lamination preferably begins only then. A leading region of the at least one lamination material is preferred 321 ; 331 the disposal facility 501 ; 504 fed, for example manually and / or by suction of the leading end of the lamination material 321 ; 331 . These are preferably two layers of lamination material 321 ; 331 , particularly one from the top lamination source 320 and one from the lower lamination source 330 . The leading area of the at least one lamination material 321 ; 331 is preferred over the rest of the lamination fabric 321 ; 331 and / or from the laminated web of material 02 separated, in particular cut off, for example by means of the preferably as a laser cutting device 504 trained cutting device 504 . The laminated web of material 02 is preferably transported along a different transport path than the leading region of the at least one lamination material 321 ; 331 . For example, the leading area of the at least one lamination material 321 ; 331 sucked upwards while the laminated web of material 02 is transported further essentially horizontally. In this way, the lamination machine can start operating 01 can be made particularly simple, because in subsequent areas, for example in the sheet delivery 500 or multiple sheet delivery 500 no handling of bare lamination fabric 321 ; 331 is necessary, but only good or bad laminated sections 04 must be treated, which in particular have different material properties than bare lamination material 321 ; 331 , for example greater stability.

The processing machine preferably has 01 at least one, in particular, higher-level machine control. In particular by means of this machine control, it is preferred to monitor whether the sheets overlap 03 is correct and / or whether a lamination proceeds as intended and / or whether a separation of the sections 04 from the material web 02 runs successfully.

The lamination machine 01 , which, as described, prefers at least one as a sheet feeder 100 trained source of material 100 for bow 03 a material to be laminated 02 has and preferably at least one flaking device 200 ; 206 ; 207 ; 208 for the shingled arrangement of unlaminated sheets 03 has to each other and preferably at least one lamination unit 310 for producing a laminated material web 02 from the bow 03 has, is preferably alternatively or additionally characterized in that along one for the laminated material web 02 provided transport route after the at least one lamination plant 310 at least one thickness control device 354 is arranged, the control area at least partially with that for the laminated material web 02 intended transport route overlaps. The at least one thickness control device 354 preferably has at least one overlap sensor 354 on. Preferably the lamination machine stands out 01 alternatively or additionally in that the at least one thickness control device 354 has at least one ultrasonic sensor and / or at least one optical sensor.

By means of the thickness control device 354 it is possible to preferably check how thick a material is that is currently arranged in your control area. The transport path of the material web preferably runs 02 and thus also the material web 02 even through this control area. Different layers of materials pass through the control area. In any case, the following are to be mentioned as possible layers: a layer of arches 03 that is laminated on both sides or a layer of sheets 03 that is laminated on only one of both sides or an area of overlap between two sheets 03 that is laminated on only one side or an area of overlap between two sheets 03 which is laminated on both sides. From the connection of a draining web of lamination fabric 321 ; 331 and a new web of lamination fabric to be unwound 321 ; 331 a connection point results, in particular a glue point. This joint is usually thicker than a bare sheet of lamination fabric 321 ; 331 . The connection point extends along the intended transport path, for example, over at least 6 mm, preferably over at least 10 mm, more preferably over at least 20 mm and even more preferably over at least 30 mm. The connection point extends independently of this along the intended transport path, for example over a maximum of 300 mm, preferably over a maximum of 200 mm, more preferably over a maximum of 100 mm and even more preferably over a maximum of 50 mm. Particularly in the case of double-sided lamination, a connection point can be made on an upper web of lamination material 321 and / or on a lower web of lamination fabric 331 appear. The above-mentioned possible layers can therefore each be provided by one or two connection points instead of simple layers of lamination material 321 ; 331 be modified.

Preferably the lamination machine stands out 01 alternatively or additionally in that the thickness control device 354 is designed at least to be between an expected thickness of the laminated material web 02 on the one hand and on the other hand an increased thickness on the other hand. The expected thickness is then, for example, a sum of the thickness of one sheet and the combined thickness of two sheets of lamination fabric 321 ; 331 . This thickness represents the desired thickness of the sections 04 represents and in normal operation corresponds to a large part of the length of the material web 02 also the thickness of this material web 02 , for example over at least 75% or preferably at least 90% of the length. In particular if, as described, at least one lamination control device 348 ; 349 is arranged, those cases are of particular interest in which a greater than the expected thickness occurs. These are essentially a first case in which an overlapping area is the control area of the thickness control device 354 happens or a second case in which at least one connection point is the control area of the thickness control device 354 happens or a third case in which both an overlap area and at the same time at least one connection point the control area of the thickness control device 354 happens.

The overlap length, in particular the overlap length of adjacent sheets 03 , is the one along the intended transport path of the material web 02 measured length on which adjacent arches 03 within the laminated web of material 02 touch.

A thickness signal is preferably a signal that is one versus the expected thickness of the laminated web of material 02 Characterized by increased thickness. In the first case, that area measured along the intended transport path, over which at least one thickness signal is generated, extends essentially over the overlap area, that is to say the overlap length. In the second case, that region measured along the intended transport path, over which at least one thickness signal is generated, extends essentially over the connection point. In the third case, the area measured along the intended transport path over which at least one thickness signal is generated also extends essentially over the connection point or is even longer, depending on the relative position of the overlap area and connection point. The length of the area measured along the intended transport path, over which at least one thickness signal is generated, is determined, for example, on the basis of the temporal length of the thickness signal and the transport speed of the material web 02 determined. The length of the region measured along the intended transport path, over which at least one thickness signal is generated, is preferred, but from a covered angle of a for transporting the laminated material web 02 provided transport roller 311 ; 312 ; 341 ; 353 ; 407 ; 408 ; 429 and its radius is determined.
