Abstract

The invention relates to forms (3, 4, 5) each with removal aids for the integrated cards (7). The removal aids involve, for example, punched sections adjoining the cards (7), similar to structure of the cards and removed from the form plane, and additionally the adhesion between the card (7) and a supporting layer (8) adjacent the removal aid is reduced. An explanation is also given of removal aids with holes which allow the integrated cards (7) to be engaged from behind from the front of the form. During the method, pressure is exerted on the punched sections, preferably using spikes, and said punched sections are bent out of the form plane. Pressure is exerted on the punched sections, similar to the structure of the cards (7), by the supporting layer (8) from behind, and on the forms with holes directly from the front. Complete removal subsequently takes place, e.g. by suction, peeling or by using a gripper. The invention also relates to devices for carrying out the method.

Description

Form with a removable card and method and device for removing diecuts from such forms

TECHNICAL AREA

The present invention relates to forms with removable cards and methods and devices for removing diecuts from such forms.

STATE OF THE ART

Forms with cards integrated in the form level are e.g. known from WO 95/20493. The integration of the cards or their generation by punching directly in the form from the material of the form is rational and has the further advantage that, apart from any additional coatings, the cards are not applied to the form and the forms therefore in printers or the like can be processed automatically.

The advantage of integration is offset by the disadvantage that the cards can be difficult to remove from the form. A solution to this problem in the sense of a removal aid is also already known from WO 95/20493: by means of a separated dance dance adjacent to the card. An edge of the card is exposed, on which the card can be grasped, for example with a fingernail.

This known removal aid solution has the advantage that it is largely self-explanatory. On the other hand, it still requires skillful manipulation by the person handling it.

Another problem arises in how the diecuts for generating the removal aid can be removed as automatically as possible during the production of the forms.

From label production is e.g. a lattice punching in an endless web with subsequent removal of the lead frame is known. With this technology, however, it is not possible to remove individual die cuts from the endless web, which can be selected in terms of number, size, shape and position.

PRESENTATION OF THE INVENTION

It is an object of the invention to provide further, easy-to-manufacture and easy-to-use removal aids for forms with integrated cards. The invention is also intended to specify methods by which individual diecuts, e.g. for the production of removal aids for cards integrated in forms, can be easily removed and removed from forms. Finally, devices for carrying out such methods are also to be specified.

According to the invention, these objects are achieved by means of forms, methods and devices as characterized in the patent claims. In the case of the forms according to claims 1 to 10, the form and the carrier material outside the card area are completely punched out from two places on the edge of the card to produce the removal aid, or only from both sides down to the depth of the adhesive layer punched. This can result, for example, in a penetration zone or a predetermined bending line. In the case of the penetration zone, a penetration hole is present or can be easily produced with the finger. These embodiments are preferably combined with a handle zone punched out in the carrier material.

In the forms according to claims 11 to 14, as a removal aid adjacent to the card, as in WO 95/20493, a die cut corresponding to the card is punched out and removed. In addition, however, a zone is provided in the area of the card adjacent to the die cut, in which there is no or only a reduced liability between the card and the carrier material.

The method according to claims 15 to 20 is particularly suitable for the removal of diecuts from forms according to claims 9-12. Pressure is exerted on the diecuts through the carrier material and some of them are thereby released while being bonded to the carrier material bent out of the form level. The diecuts which are partially bent out of the form plane, preferably with an edge area or a corner, can subsequently be completely removed simply by suction and / or peeling.

A mandrel is preferably used to generate the lifting pressure on the diecuts, with which the carrier material is pierced from behind. So that the bond between the endless web and the carrier material does not also loosen in the vicinity of the diecuts, this is preferably fixed by suitable means.

Claim 21 relates to an application of the aforementioned method for producing a form with a die-cut corresponding to the structure of the card and a zone in which the liability between the card and the carrier material is released. At the same time as the pressure is exerted on the die cut, a corresponding pressure is exerted on a corner of the card, this is lifted off the carrier material and subsequently passed under with a doctor blade to form the zone mentioned.

Claim 22 relates to a method with the application of pressure from the front of the form for the removal of diecuts to the rear.

The device according to claims 23 to 26 is characterized above all by a mandrel roller around which the forms can be deflected.

In the method according to claim 27, diecuts, which are held in the form by a carrier layer, are bent out of the form level in a first step, are gripped on their bent-out part in a second step and in a third step by means of a relative movement between the Gripping tool and the form completely removed.

Claims 28-33 relate to devices for carrying out the method according to Claim 27. Exemplary embodiments of the invention are explained below with reference to the drawings.

WAYS OF CARRYING OUT THE INVENTION

1 shows a section of an endless web 1 made of forms 3, 4 and 5 of the same type, which are delimited from one another by perforation lines 2. Forms 3 and 5 are only partially shown. The endless web 1 consists, for example, of paper. In each form 3, 4 or 5, a card 7 is punched out of the material of the endless web by means of a fully circulating, web-free punching line 6. So that the cards 7, which have no or practically no connection to the material surrounding them, do not fall out of the endless web 1, pieces of carrier material are applied on the back, covering the region of the cards, which have a carrier layer 8 and comprise an adhesive layer 9. The resulting structure is shown in section in Fig. 2. The adhesive layer 9 must be set in such a way that the cards 7 on the one hand are held sufficiently firmly and securely in the plane of the endless web and do not detach prematurely when the forms are further processed, for example in a printer, but on the other hand also without too much difficulty and above all Have it removed from the form non-destructively. The adhesive layer 9 can also be designed such that it detaches from the carrier layer 8 together with the card 7. In this case, card 7 is a "self-adhesive label" that can be stuck on again at another point. However, the adhesive layer 9 can also be designed such that it remains completely on the carrier layer 8 when the card 7 is removed, so that the card is non-adhesive and can be used, for example, as an identification card. One speaks in in this case from a peeling layer. This variant is shown in FIG. 2 and all other figures with the exception of FIG. 13.

The three-layer structure shown in FIG. 2 corresponds to the simplest embodiment. In particular if the card 7 is to serve as an identification card, additional layers can be advantageously provided, in particular made of a film material, for stiffening and sealing. Corresponding examples can be found in the already mentioned WO 95/20493, to which reference is expressly made.

To facilitate the removal of cards 7, i.e. As a removal aid, by means of a punching line 10 adjacent to the cards, additional punched-out areas are provided, from which the resulting punched pieces 11 are removed. One edge of the cards 7 is thus a bit free and can e.g. with a fingernail, undergrips and peeled off.

The punching line 10 preferably runs in an arc shape and further preferably strikes the punching line 6 at an acute angle. Both punching lines 6 and 10 have the same punching depth and can be attached with the same punching tool in the same operation. Punching is preferred on one side of the card, i.e. attached to one of the two sides oriented in the direction of the extent of the endless web 1 and not to a transverse side and also not to a corner of the card.

2 shows under a), represented by the arrows, the punching process, under b) the removal of the punch 11 for the manufacture of the removal aid and under c) the removal of the card 7. In the exemplary embodiment of FIG. 3, in the area of the card 7 adjacent to the removal aid generated by the punching line 10, a zone 21 is provided which extends in the longitudinal direction of the form and in which a zone is reduced between the card 7 and the carrier layer 8 compared to the other card areas or there is no liability at all. The card 7 can thereby be gripped and removed more easily at its edge which is exposed in the area of the removal aid. The zone 21 can extend over the entire carrier material, ie be "endless" in the carrier material, or its extension can be limited to the area of the card 7 or even only the removal aid. The latter embodiment shown in FIG. 4 has the advantage that the card corners, which represent generally critical areas, are not affected by the reduced liability.

In zone 21 e.g. 5, alternatively, a separating coating 22, for example siliconization, can be inserted between the card 7 and the adhesive layer 9 in the zone 21, as shown in FIG 6 shows. Liability can also be released mechanically in Zone 21. To remove liability e.g. In order to be able to execute it on a running endless web by means of a squeegee 23, the corner of the card which is at the front in the running direction of the endless web must be bent out of the form level so that it can be passed under with the squeegee. This results in a zone 21 which extends approximately over the area of the card. Fig. 7 shows this variant.

FIGS. 8-12 relate to embodiments in which a penetration zone is provided as a removal aid.

In the embodiment of FIGS. 8 and 9, the punching line 10 between the two locations 24 and 25 located approximately on the edge of the card is full of all materials or layers of the form punched out, which is indicated in Fig. 8 by the dashes on line 10. It frames, as will be made clear, a penetration zone 26. In addition, from the back of the form, only in the carrier layer 8 is a grip zone 28 punched out in the carrier layer 8 by a stamped line 27, which also extends between the positions 24 and 25. Since the carrier layer 8 is not punched through between the two points 24 and 25 along the edge of the card, the three punch lines 6, 10 and 27 result in a special punched piece 29 which, as can be seen in FIG. 9a, only remains in the grip zone 28 is glued to the form. 9b shows the diecut 29 downward, ie towards the back of the form, removed from the form. This results in a structure in the form with a through hole 30. Adjacent to the through hole 30, the back of the card is exposed in the grip zone 28. Card 7 can therefore be grasped from the front of the form with a finger through the through hole 30 from behind in the grip zone 28 and can be removed particularly easily from the form.

This type of removal aid is also self-explanatory in a special way and requires practically no skill on the part of the user. Another advantage of this solution is that the adhesive value of the adhesive layer 9, which holds the card 7 on the carrier layer 8, can be chosen to be higher, without this affecting the detachability of the card 7. The grip zone 28 should be of sufficient size so that the finger does not come onto the carrier material. The design of the grip zone 28 in the form of half an ice or even approximately triangular is of particular advantage in terms of operational safety.

In the embodiment of FIGS. 8 and 9, the two punching lines 10 and 27 can be designed so that their ends meet cross each other in the area of positions 24 and 25. The punching line 27 preferably projects with its ends into the passage area 26 and the punching line 10 runs in the area of the two points 24 and 25 a short distance parallel to the edge of the card (not shown in FIG. 8). On the other hand, it is not disadvantageous if the punching lines 10 and 27 do not cross and the punching line 27 even runs completely within the card area. If sufficient pressure is exerted when the die 29 is removed from the front of the form, the carrier layer 8 tears in the area of the two points 25 and 25 and tear lines 31, 32 form up to the line 27, as is shown, for example, in FIG. 10 is shown. Thereafter, the carrier material is also completely separated from the surrounding carrier material 8 in the grip zone 28, as in the example of FIG. 8, as a result of which the diecut 29 can be removed.

In Fig. 10, the punch line 27 is straight. This has the advantage that it can be carried out simply as a cut 27 'in the running endless path, for example with a rotating circular knife or a pulling blade knife, and in this way a more complex punching from the back of the form becomes superfluous. It is then only necessary to attach the punching lines 6 and 10 from the front of the form, which can be done in one operation with the same punching tool. The cut 27 'can be continuous, i.e. extending over the entire carrier material or only within the map area.

11 and 13 show two further embodiments with a penetration zone 26 and a cut 27 'made on the rear side in the carrier material. Punching lines along which all layers are completely punched are again provided with cross lines. In FIG. 11, two such punching lines 33 and 34 start from the locations 24 and 25 on the edge of the card, which produce a kind of flap between them in the passage area 26. In this embodiment, there is no hole in the form before card 7 is removed. When pressure is applied from the front to the tab mentioned, as in the previous example, tear lines 31 and 32 form from the points 24 and 25 to the cut 27 '. In contrast to the previous example, the “diecut” designed as a tab remains connected to the form here. To remove the card, however, it can be pushed backwards, which in turn creates a through hole through which the card 7 can be gripped.

FIG. 12 shows a combination of the embodiments of FIGS. 10 and 11. Here, the free ends of the two punch lines 33 and 34 are connected by a perforation line 35. In this embodiment, too, there is no hole in the form before the card 7 is removed. To remove the card 7, the material is first completely cut along the perforation line 35 by exerting pressure on the penetration zone 26 with the finger. This creates a structure which corresponds to that shown in FIG. 10 and the further description of which can be dispensed with here.

FIG. 13 shows an embodiment which corresponds to that of FIG. 8 with the difference that here the card edge between the locations 24 and 25 is also punched through all layers. As a result, a diecut is formed in the penetration zone 26, which no longer has any connection with the surrounding material and easily falls out of the form. Another die cut is produced in the grip zone 28, but this adheres to the back of the card. Leaving this further diecut on the back of the card is advantageous if the card 7 is designed as a self-adhesive label is, ie the adhesive layer to the back of the card has a stronger adhesion than to the carrier layer and would not come off in the grip zone 28 together with the other diecut. Removing the further diecut would therefore only expose the sticky back of the self-adhesive label in a disadvantageous manner. In this embodiment, the further diecut is therefore preferably removed only after the card 7 has been manually removed by the user.

In all of the exemplary embodiments described above, the punch-out for the removal aid was provided on one side of the card 7, the card corners deliberately being left out. 14 now shows an embodiment which just includes a corner 36 and in which the locations 24 and 25, from which fully punched lines 33 and 34 originate, lie on both sides of this corner 36 on the edge of the card. The punched lines 33 and 34 extend here along a imaginary line that intersects the corner 36, along which, due to the punched lines 33 and 34, the form can be easily bent. Due to the inherent rigidity of the card 7, the corner 36 detaches from the carrier layer 9 and protrudes freely and easily graspable from the form with the finger. In this embodiment, neither a punching nor an incision in the carrier material is required on the back of the form.

FIGS. 15 and 16 show a similar embodiment to that of FIGS. 8 and 9, the punching line 10 between the locations 24 and 25 on the card edge, however, being of the same depth as the punching line 6, ie it only extends up to Adhesive layer 9 down. For this purpose, the punching line 27, which is likewise only made up to the adhesive layer from the back of the form, is designed as a completely circumferential, self-contained line which surrounds the punching line 10. Although the material is not completely punched through here, the only slight side result is Offset of the punching line 17 with respect to the punching line 10, where the punching line 27 runs next to the punching line 10, a similar punching die 29 as in the example of FIGS. 8 and 9 and, after it has been removed, a through hole 30 and a rear grip zone 28. The advantage of this embodiment 8 and 9 is that the punching lines 10 on the one hand and 27 on the other hand can each be made uniformly deep and also no longer cross each other in the area of the points 24 and 25.

FIGS. 17-19 relate to embodiments of the type of FIGS. 15 and 16, the punched-outs 10 and 27 for the removal aid, preferably in the running direction of the endless web, being shifted into the area of a card corner. The punch line 27 is designed here as a circle. The punching line 10 lies on a concentric inner circle, but ends on both sides again at the edge of the card or the punching line 6. In FIG. 17 the removal aid is positioned symmetrically to the corner of the card, while in FIGS. 18 and 19 it is shortened or shortened The longer card edge is slightly shifted, which makes it easier to remove the die-cut 29 by bending it out of the plane of the form.

In principle, even in the embodiments according to FIGS. 10 to 14, the punching line / s, along which the material is fully punched from one side, could be replaced by two punchings that are offset to one side and executed on both sides of the form.

FIG. 20 shows a device for the automatic removal of diecuts 11 according to FIG. 2 from a running endless web 1, as shown, for example, in FIG. 1 and which has already been punched to form perforation lines 2, cards 7 and cards Removal aids for the cards 7 is provided. Subdivided by the perforation lines 2 into the forms 3, 4 and 5 Continuous path 1 runs through the device of FIG. 20 from right to left in the direction of the arrows indicated. The adhesive layer 9 is omitted in FIG. 3 for simplicity of illustration.

In the device of Fig. 20, the endless web 1 is first deflected over a mandrel roller 12 provided with mandrels 13, the pieces of carrier material 8 glued onto it being directed towards the roller 12, i.e. come into contact with her. The mandrels 13 are attached in such a way that they pierce the carrier material 8 in the area of the diecuts 11 (from the rear), more precisely in the area of the front "corner" (in the direction of travel of the endless web 1) of the diecuts 11. With regard to their length However, the mandrels 13 are designed such that they do not also pierce the material of the punched line 11, but rather can only exert a certain release pressure thereon. It is sufficient to detach the aforementioned front corner of the diecuts 11 from the carrier material 8 and to bend them out of the plane of the endless web 1 somewhat. Provided with a bent-out front corner in this way, the diecuts 11 can easily be removed in a subsequent step by peeling and / or suction.

Special hold-down devices can be provided so that when the carrier material 8 is pierced and the front corners of the die-cuts 11 are not pierced, the bond between the carrier material 8 and the continuous web 1 is not released in the area adjacent to the die-cut members. 20, rollers 14 are provided for this purpose, which are positioned in the axial direction outside the area of the mandrels 13 and thus in front of and behind the cutting plane of the drawing directly adjacent to the axial passage area of the diecuts 11 and on the top of the endless web 1 preferably unroll. On the other hand, a certain loosening of the bond between the form and the carrier material in the area of the grip edge exposed by the removal of the diecuts on the integrated cards may be desirable, because this in itself makes it easier to grasp and remove the cards. A permanent deformation in the form and / or the carrier material in the area of the exposed grip edge can even be generated by the corresponding design of the mandrel roller 12 and / or the rollers 14, which additionally facilitates the release of the cards.

The definitive removal of the diecuts 11 takes place in the device of FIG. 20 on a roller 15, around which the endless web 1, again with the carrier material pieces 8 to the roller or with the corners of the diecuts 11 set out, is turned around is steered. The suction opening 16 of a suction device, not shown, is arranged in the apex of the deflection, partially encompassing the roller 15. A doctor blade for additional peeling of the diecuts 11 is designated by 17. Sucking off and / or peeling off the diecuts 11 works after the preparatory detachment and installation of their front corners even if the adhesive layer detaches together with the diecuts, i.e. does not remain on the carrier material.

In the device of FIG. 20, a further deflecting roller 18 is provided between the mandrel roller 12 and the deflecting roller 15, which is dispensable per se, but by which, however, a "straight" passage of the endless web 1 through the device with matching inputs and Direction of exit of the endless web 1 becomes possible. The endless web 1 is deflected around the deflecting roller 18 with the corners of the diecuts 11 bent out toward the roller. So that the bent corners are not pressed down and glued back to the carrier material 8, the roller 18 has a kind of gap with a smaller diameter (circle 19) in the axial passage area of the diecuts 11. Alternatively two separate rollers spaced apart from one another could also be used.

After the diecuts 11 have been removed, the piercing points of the mandrels 12 can be seen in the carrier material 8, but these do not further interfere. In Fig. 20 these are designated 20. Depending on the material properties of the endless web and the carrier material, a deformation without piercing the carrier material may be sufficient to detach and bend out the corners of the diecuts 11.

The above-described removal of the diecuts by repeatedly deflecting the forms, which are still connected as an endless web, around rollers has the advantage that it can be carried out rationally and precisely fully automatically. In principle, however, it is also possible to carry out the process in the plane, i.e. to be carried out on stretched forms or a stretched endless web, in particular step by step, in a so-called "stop and go" process. The execution of the method on individual, non-contiguous form sheets would of course also be conceivable.

With the above-described method, using thorns arranged in pairs next to each other on the mandrel roller, in addition to the front corner of the diecuts 11, the front corner of the card 7 in the direction of travel of the continuous web can also be pressed out and set up somewhat, as is the case under the card edge the embodiment shown in FIG. 7 with a doctor blade 23 is required. In Fig. 3 the piercing points of the mandrels are shown and designated 37 and 38.

The described method can also be used in a somewhat modified form to remove the diecuts 29 in the embodiments according to FIGS. 8-10 Pressure is applied to the diecuts 29 from the front of the form and not through the backing material. The device of FIG. 20 can also be used if the endless web is reversed, that is to say with its front side passing through it toward the mandrel roller 12. Instead of sucking off and / or scraping off the diecuts 29 that were pressed down in the first step, but then still adhering to the carrier layer, it would also be possible to arrange them in a curved manner or at an angle to the running direction of the endless web, for example simply by means of two metal sheets let formed channel run in, in which they are completely separated from the carrier layer by a kind of peeling. Such a channel would usefully be arranged under the endless web and, apart from this, would also be open towards the bottom, so that the stampings 29 can fall out of the channel after being peeled off.

FIGS. 21-23 show a further method or a further device for the automatic removal of diecuts 29 from a running endless web 1, in particular those according to the embodiments according to FIGS. 8-10 and 15-19 an upper mandrel roller and 41 denotes a lower roller, between which the endless web 1 passes through. A sleeve 44 and a rod 45 are axially movably guided in an eccentric bore 43 in the lower roller 42. A first gripper plate 46 is fastened to the right end of the sleeve 44 and a second gripper plate 47 is fastened to the right end of the rod 45. With their respective left end, the sleeve 44 and the rod 45 run when the roller 41 rotates on a fixed control disk 48 with an approximately helical control surface against which they are pressed by a spring 50. The spring 50 is arranged in a region of the bore 43 with a larger diameter. It is supported on the one hand on a shoulder 51 at the end of this area and on the other hand on a pin 52. This is through a cross hole in the Rod 45 and inserted through a longitudinal slot 49 in the sleeve 44 and protrudes with its ends into inner grooves 53 in the eccentric bore 43. As a result, sleeve 44 and rod 45 are axially displaceable relative to one another in the roller, insofar as the longitudinal slot 49 permits this, and are non-rotatably fixed relative to the roller 41. A bushing 54 closes off the enlarged area of the bore 43 to the left. The two rollers 40 and 41 are synchronized with one another and the endless track 1 by means not shown, such as a gear.

21, 22 and 23 a) show the described device in a state in which a punch 29 straight down from the mandrel 42 arranged in the upper roller 40 partially out of the plane of the endless web 1 between the two open gripper plates 46 and 47 is bent out. In Fig. 23 b), the rollers 40 and 41 are rotated a few degrees. The left end of the rod 45 now engages in a groove 55 which is open in the direction of rotation in the control disk 48. As a result, the two gripper plates 46 and 47 could close and clamp the part of the diecut 29 bent downward. So that there is no collision with the mandrel 42, a recess 56 is provided in at least one of the gripper plates 46 or 47. 23 c) shows the two rollers 40 and 41 turned a little further. The sleeve 44 and the rod 45 are moved together a further distance to the left, which is made possible by an expansion of the groove 55 in its outer region. When moving into this position there is complete detachment, shearing or tearing off of the punched piece 29 clamped between the gripper plates 46 and 47.
