EP3693302B1 - Adhesive piece - Google Patents

Description

The invention is directed to an adhesive piece according to the preamble of claim 1.

It is known from the state of the art through prior public use to introduce webs of material into treatment/processing arrangements. This is generally done manually or manually. The prior art also teaches the manual removal of release liners from double-sided adhesive patches attached to webs of material to join them together. This is often associated with a not inconsiderable amount of time and is often not carried out particularly carefully.

The U.S. 2013/183473 A1 discloses an elongated double-sided adhesive tape of the generic type for splicers, printers and the like. The adhesive tape comprises a backing layer, a first adhesive layer arranged on an upper side of the backing layer, and a second adhesive layer arranged on an underside of the backing layer. Further, the adhesive tape has a first release tape covering the first adhesive layer and being slightly wider or wider than it with respect to the adhesive tape and forming a finger portion. The first separating strip is thus slightly wider or wider than the first adhesive layer perpendicularly to a longitudinal direction or unwinding direction of the adhesive tape. A second divider is below placed on the tape. Such an adhesive tape is not always easy or easy to handle.

From the U.S. 2004/0045658 A1 an elongate splicing tape is known which has a base, an adhesive layer on top of the base and two adhesive strips on an underside of the base. Furthermore, the splicing tape has a removable release liner on the adhesive layer. The separating layer protrudes from the adhesive layer in the transverse direction of the splice tape.

The U.S. RE 38,356 E discloses an elongate splicing tape for splicing connections. The splicing tape comprises a backing having an adhesive layer on one side and a first release sheet extending approximately half the width of the adhesive layer. Furthermore, the splicing tape has a second release film which extends over the other half of the adhesive layer.

The present invention is therefore based on the object of eliminating the problems of the prior art. An adhesive piece is to be delivered whose separating cover can be removed particularly easily from an adhesive carrier.

According to the invention, this object is achieved by the features specified in the main claim 1 .

The essence of the invention lies in simplifying the handling of material webs or material rolls to be processed/processed.

The separating cover protrudes at least in regions in the longitudinal direction in relation to the adhesive carrier and is thus particularly easy to remove removable from the adhesive carrier. It also protrudes laterally in the transverse direction relative to the adhesive carrier.

The guide device 77 on the output side runs out of the material web splice arrangement 1 via the material web outlet 44 .

Each guide device 51, 52, 57, 60, 62, 64, 65, 70, 73, 75, 77 comprises guide elements arranged in pairs opposite one another, which are correspondingly identical in shape and rail-like or link-like. The guide elements are each arranged laterally adjacent to or laterally outside of the web of material 3, 4, 7 to be drawn in. They are preferably arranged in the transverse direction of the web of material 3, 4, 7 at a distance from the web of material 3, 4, 7 to be drawn in or its longitudinal edge. The guide elements are open towards the web of material 3, 4, 7 to be drawn in and have a U-shaped cross section, for example.

The material web splicing arrangement 1 comprises at least one material web clamping device 78 for clampingly holding the material web 3, 4, 7 ( Figures 11 to 14 ).

The material web clamping device 78 has a profile-like rigid crossbeam 79 which extends in the transverse direction of the material web 3, 4, 7 to be drawn in and protrudes laterally in the transverse direction of the material web 3, 4, 7 to be drawn in. The crossbeam 79 engages in mutually opposite guide elements and is thus guided in a displaceable manner perpendicular to its extension. The crossbeam 79 can be displaced along the slotted guide 49 and is thus able, depending on its position, to perform translational and/or arcuate movements or the like to execute. It extends perpendicularly between the opposing guide elements.

The crossbeam 79 has a material web receiving opening 80 which is open counter to the feed direction or transport direction 37 . It is essentially U-shaped. The cross member 79 has a base 81 opposite the material web receiving opening 80 and a holding web 82 protruding from the base 81 as well as an outer web 83 protruding from the base 81 . The holding web 82 and outer web 83 run parallel and spaced apart from one another.

During a feed process, the holding web 82 interacts with the web of material 3, 4, 7 to be fed in, while the outer web 83 is arranged at a distance from it.

The crossbeam 79 supports a clamping bar 84 which is arranged between the retaining bar 82 and the outer bar 83 and can be pivoted relative to them. Starting from the base 81 , the clamping bar 84 preferably protrudes over the holding web 82 and the outer web 83 .

Adjacent to the first and second feeder input 53 or 54 of the first guide device 50 on the input side and adjacent to the first and second feeder input 66 or 67 of the second guide device 63 on the input side, an activation device 85 is preferably arranged on the opposite guide elements, which comprises an electrical pulse receiver 86 included. The activation device 85 is assigned to the clamping bar 84 . The pulse receiver 86 is connected to the clamping bar 84 and is able to pivot it.

Two coupling chains 87 are arranged on the base 81 opposite the clamping bar 84 . The coupling chains 87 run in the mutually opposite guide elements of the guide devices 51, 52, 57, 60, 62, 64, 65, 70, 73, 75, 77 and can be displaced by a motor. The link guide 49, the material web clamping device 78 and the coupling chains 87 together with their displacement drive/s are part of a material web drawing-in device.

The operation of the material web splicing arrangement 1 is described below by way of example. This is done by 1 went out. At 1 the finite first web of material 4 is unrolled from the first roll of material 5 and thus promoted. It was drawn into the material web splice arrangement 1 by means of the material web drawing-in device while the finite first material web 4 unrolled from the first material roll 5, which will be described in detail below.

The finite first web of material 4 is guided to the cutting and connecting device 17 via the first feed roller 16, where the finite first web of material 4 is deflected. It is passed between the spaced-apart pressure rollers 33, 36 and rests against these on the peripheral side in some areas.

Downstream of the cutting and connecting device 17, the finite first material web 4 or the endless material web 3 is introduced from above into the threading assistance arrangement 38 and wraps around its two conveyor rollers 39, 40, lying against the conveyor rollers 39, 40. The threading assistance arrangement 38 favorably supports the transport of finite first web of material 4 or the endless web of material 3 and is driven accordingly.

The finite first material web 4 or the endless material web 3 is then guided around the first deflection roller 41 on the storage carriage 42 . The finite first material web 4 or the endless material web 3 is then guided around the stationary second deflection roller 45 . The finite first material web 4 or the endless material web 3 is then guided around the third deflection roller 46 on the storage carriage 42 . The finite first material web 4 or the endless material web 3 is then guided around the stationary fourth deflection roller 47 . The finite first material web 4 or the endless material web 3 is then guided around the fifth deflection roller 48 on the storage carriage 42 . The finite first material web 4 or the endless material web 3 then leaves the material web splice arrangement 1 via the material web outlet 44.

The finite first web of material 4 or the endless web of material 3 extends for the most part adjacent to the link guide 49.

The storage carriage 42 is arranged adjacent to the material web outlet 44 . The first vacuum roller 25 is arranged at a distance from the first transport roller 27 . The table means 23 is located adjacent to the connecting means 21,22. It is spaced apart from the preparing means 19,20.

The cutting and connecting device 17 is in its inactive state. In this state, the finite first web of material 4 or the endless web of material 3 is merely passed through the cutting and connecting device 17 .

At 1 the finite second material web 7 was drawn into the material web splice arrangement 1 by means of the material web drawing-in device, while the finite second material web 7 unrolled from the second material roll 8 . The material web splicing arrangement 1 has received the second material roll 8 and also the first material roll 5 after alignment in their circumferential direction in an exactly defined starting position by means of the material roll preparation arrangement 2 .

To pull in the finite second web of material 7 , the clamping bar 84 is in its clamping position and is pivoted in the direction of the web of material holding web 82 while clamping the finite second web of material 7 . The finite second material web 7 to be drawn in is thus arranged between the holding web 82 and the clamping bar 84 and held in a clamped manner. It passes through the material web receiving opening 80. The coupling chains 87 are drawn in synchronously by a motor, so that the crossbeam 79 together with the fixed finite second material web 7 is pulled along the connecting link guide 49 to the second preparation device 20. The cross member 79 is pulled around the transport roller 28 so that it faces the second vacuum roller 26 . Due to the unwinding direction of the second roll of material 8 , the finite second web of material 7 enters the link guide 49 via the free second feed entrance 67 .

The second outlet 69 of the inlet-side second guiding device 63 and the second inlet of the second guide arc device 70 are arranged adjacent to one another, so that the finite second web of material 7 is able to enter the second guide sheet device 70 from the entrance-side second guide device 63 in the feeding operation. The second outlet end 72 of the second curved guide device 70 and the second connection 74 of the essentially rectilinear second guide device 73 are arranged adjacent to one another, so that the finite second material web 7 is capable of moving from the second curved guide device 70 into the essentially rectilinear second guide device 73 during the infeed process to get. The second preparation device 20 together with the second guide arc device 70 have been correspondingly displaced along the guide 24 for this purpose.

How 2 illustrated, for a splicing process, the table device 23 then moves along the guide 24 to the second preparation device 20. If the second preparation device 20 and the table device 23 are arranged adjacent to one another, the threaded finite second material web 7 is between the second preparation device 20 and the table device 23 held tightly. In particular, the finite second material web 7 is held between the second transport roller 28 and a holding element 88 of the table device 23 while deforming the latter. The table device 23 and the second preparation device 20 assume a holding position.

Then the table device 23 moves along the guide 24 to the second preparation device 20. The table device 23 and the second preparation device 20 together with the second arched guide device 70 move together along the guide 24 in the direction of the second vacuum roller 26, which in turn moves in the direction of the second preparation device 20 moves. When the second transport roller 28 and the second vacuum roller 26 are arranged adjacent to each other, the second Output 69 of the second guide device 63 on the input side and the second input of the second guide arc device 70 are arranged separately or at a distance from one another. The second exit end 72 of the second guide arc device 70 and the second connection 74 of the essentially rectilinear second guide device 73 are separated from one another or arranged at a distance from one another ( 3 ).

The second transport roller 28 and the second vacuum roller 26 are then driven in rotation in opposite directions in such a way that the finite second material web 7 is conveyed back in the opposite direction to its actual drawing-in direction and a double-sided adhesive splice piece 89 arranged at the end of the finite second material web 7 is placed between a second transport roller 28 and the second vacuum roller 26 formed gap. The splice piece 89 is adhesively connected to the finite second web of material 7 with an inner adhesive surface. The splice piece 89 faces the second vacuum roller 26 with its detachable, non-adhesive separating cover 90 and rests with the separating cover 90 on the latter. The second vacuum roller 26 is active and thus sucks in the separating cover 90 of the splice piece 89 with the vacuum it generates and thus removes it from the actual splice piece 89, exposing an outer adhesive surface of the splice piece 89 opposite the inner adhesive surface. The second transport roller 28 and second vacuum roller 26 are part of a separator cover removal device.

The second preparation device 20 and the table device 23 then move in the coupled state along the guide 24 in the direction of the first preparation device 19 or to the first connecting device 21, the finite second material web 7 being clamped between the Table means 23 and the second transport roller 28 is held. The second preparation device 20 and the table device 23 move away from the second vacuum roller 26 ( figure 5 ). The rotation of the second transport roller 28 is blocked.

The rotation of the second transport roller 28 is then released again. In particular, as a result of the displacement of the table device 23 and the second transport roller 28 as a unit, the second transport roller 28 is pivoted in such a way that the splice piece 89 reaches a splice position facing upwards.

How figure 5 , 6 show, the second transport roller 28 is moved under the first connecting device 21 so that the splice piece 89 faces the first connecting device 21 . The endless material web 3 or finite first material web 4 is pressed against the adhesive splice piece 89 facing the first pressure roller 33 by shifting the first pressure roller 33 of the first connecting device 21 . This results in an adhesive connection of the endless web of material 3 or finite first web of material 4 to the finite second web of material 7. The supply of the finite first web of material 4 to the endless web of material 3 is stopped. The finite first web of material 4 is separated from the endless web of material 3 by means of the first cutting blade 32 .

By moving the storage carriage 42 away from the material web outlet 44, the loops formed by the endless material web 3 are broken up so that the endless material web 3 remains the material web splice arrangement 1 without interruption or is conveyed without interruption.

At 8 the finite second material web 7 is now unrolled from the second material roll 8 . The first roll of material 5 is now prepared analogously to the previous description for later unrolling. The feeding of the finite first material web 4 into the material web splice arrangement 1 takes place essentially analogously with the material web feeding device.

How 9 shows, for a splicing process, a splice piece 89 arranged on the finite first web of material 4 is adhesively connected to the endless web of material 3 or finite second web of material 7, essentially analogously to the previous description, so that the finite first web of material 4 is adhesively bonded to the endless web of material 3 connected is. The feeding of the finite second material web 7 is now stopped.

The first output 56 of the first guiding device 50 on the input side and the first input 58 of the first guiding arc device 57 are arranged adjacent to one another, so that the finite first material web 4 is able during the infeed process to get from the first guiding device 50 on the input side into the first guiding arc device 57. The first exit end 59 of the first curved guide device 57 and the first connection 61 of the essentially rectilinear first guide device 60 are arranged adjacent to one another, so that the finite first material web 7 is capable of moving from the first curved guide device 57 into the essentially rectilinear first guide device 60 during the infeed process to get. The first preparation device 20 together with the first guide arc device 57 have been displaced accordingly along the guide 24 for this purpose.

If the material web splicing arrangement 1 is already in operation and a material web 3, 4 or is being unwound or conveyed, the new finite material web 4 or 7 is fed via the material web drawing-in device as described only up to the respective transport roller 27 or 28 led.

If, on the other hand, there is still no material web in the material web splice arrangement 1, the respective finite material web 4 or 7 is fed completely into the material web splice arrangement 1 up to its material web outlet 44 or up to an adjacent production arrangement or -device retractable.

The first output 56 of the first guiding device 50 on the input side and the first input 58 of the first guiding arc device 57 are then arranged adjacent to one another, so that the finite first material web 4 is able during the infeed process to get from the first guiding device 50 on the input side into the first guiding arc device 57. The first exit end 59 of the first curved guide device 57 and the first connection 61 of the essentially rectilinear first guide device 60 are arranged adjacent to one another, so that the finite first material web 7 is capable of moving from the first curved guide device 57 into the essentially rectilinear first guide device 60 during the infeed process to get. The first preparation device 20 together with the first guide arc device 57 have been displaced accordingly along the guide 24 for this purpose. Alternatively, the second outlet 69 of the second guide device 63 on the inlet side and the second inlet of the second arched guide device 70 are arranged adjacent to one another, so that the finite second material web 7 at the feeding operation is able to enter the second guide sheet device 70 from the entrance-side second guide device 63 . The second outlet end 72 of the second curved guide device 70 and the second connection 74 of the essentially rectilinear second guide device 73 are arranged adjacent to one another, so that the finite second material web 7 is capable of moving from the second curved guide device 70 into the essentially rectilinear second guide device 73 during the infeed process to get. The second preparation device 20 together with the second guide arc device 70 have been correspondingly displaced along the guide 24 for this purpose.

The coupling chains 87 are drawn in synchronously by a motor, so that the cross member 79 together with the fixed finite second material web 7 is pulled along the link guide 49 up to the material web outlet 44 or beyond it.

The material web clamping device 78 is preferably automatically or motorically shifted into its initial position for receiving the respective finite material web 4 or 7 . To accommodate the respective finite web of material 4 or 7, the holding web 82 reaches under the respective finite web of material 4 or 7. For this purpose, a free section of the respective finite web of material 4 or 7 to be accommodated is at a distance from the material web sections of the respective material roll 5 or 8 arranged underneath arranged. The material web 4, 7 passes through the material web receiving opening 80.

When the crossbeam 79 reaches a correct position in relation to the finite web of material 4, 7 or its end, the web of material detection element supplies a corresponding electrical trigger signal, which preferably motorized, displacement of the clamping bar 84 causes in its clamping position. The correct position of the cross member 79 in relation to the finite material web 4, 7 or its end can preferably be achieved since the material web splice arrangement 1 receives the material roll 5, 8 in an aligned or precisely defined initial position and thus already knows where the End of the respective web of material 4, 7 on the roll of material 5, 8 is located. The crossbeam 79 is then moved into its desired position by means of the coupling chains 87, with the respective finite web of material 4 or 7 being drawn in. A fully automated recording of the roll of material 5, 8 is possible. Likewise, a fully automated infeed of the material web 4, 7.

The control or actuation of the individual units, such as preparation devices 19, 20, connecting devices 21, 22, material web feed device and/or separating cover removal device, is preferably carried out by at least one corresponding electrical or electronic actuation or control unit.

The endless web of material 3 is fed together with another endless web of material to a corrugated cardboard production device for producing a corrugated cardboard web laminated on one side. This comprises a corrugating device with rollers for producing a corrugated web from one of the endless webs of material. In order to connect the corrugated web to a flat web from the other endless web of material, the corrugated cardboard production device has a glue application device which applies glue to tips of the corrugation of the corrugated web. The corrugated cardboard production device has a pressing module for pressing the smooth web against the glued corrugated web, whereby the one-sided laminated Corrugated cardboard web is made from corrugated web and smooth web. A reverse use of the material webs is alternatively possible.

In the following, with reference to the Figures 15 to 18 a second embodiment of the material web holding device is described. Identical parts are given the same reference numbers as in the previous embodiment, the description of which is hereby explicitly referred to. Structurally different but functionally identical parts are given the same reference numbers with an "a" after them.

In comparison with the previous embodiment, the material web holding device is not designed as a material web clamping device 78, but as a material web suction device 78a. The material web suction device 78a has a cross member 79a, which essentially encloses an interior space and is designed, for example, as a rectangular profile body. Flow openings 91 lying opposite one another are formed in the cross member 79a.

The cross member 79a is in fluid communication with a suction source 92 . In the active state of the suction source 92, the web of material 4, 7 to be drawn in is sucked onto the crossbeam 79a and lies firmly against it in the region of the flow openings 91 adjacent to the web of material 4, 7 to be drawn in.

The function of the material web suction device 78a or the corresponding material web drawing-in device is essentially analogous to that of the material web clamping device 78.

The expressions “upstream”, “downstream”, “on the input side”, “on the output side” or the like used here relate in particular to a conveying direction of an associated web of material.
