description

The invention relates to a device for producing blanks, in particular collars, from packaging material, preferably for packs for cigarettes, wherein a material web for producing the blanks is guided by preferably a plurality of processing devices, in particular an embossing device and / or a cutting device or the like, in which Material web is subjected in each case at least one processing step, according to the preamble of claim 1.

Devices of the type mentioned are known from practice in different versions. As a rule, the material web passes through a plurality of processing devices in which the material web or the collar is subjected to different processing steps. It is conceivable, for example, an embossing of the collar, followed by the attachment of grooves or scratches and finally the separation of the collar by attaching a transverse separating cut.

A problem with the use of such embossing devices or embossing apparatus is the required conversion during a product change. In this case, an exchange of individual or several processing facilities is usually required. In some cases, individual processing facilities can also be completely eliminated. Such conversion measures are usually complex and time-consuming. In addition, the device should be flexible and allow adaptation to as many different products to be produced or collar. In addition, the device should be integrated as well as possible in existing packaging machines.

CONFIRMATION COPY On this basis, the present invention seeks to further develop devices of the type mentioned.

An apparatus for achieving this object has the features of claim 1. It is therefore provided that the processing means together form a processing apparatus, wherein the number and arrangement of the processing means is adaptable within the processing apparatus to the blank to be produced. Another special feature may be that the processing facilities are at least partially coupled by a common transmission, and that the distance between at least some processing equipment while maintaining the coupling is adaptable by the transmission, in particular by an adjustable, preferably pivotable, storage of idler gears for coupling of drive shafts of processing equipment. As a result, the device is easily adaptable to the production of collars of different lengths.

In a preferred embodiment of the device can be provided that the processing facilities are arranged at predetermined distances from each other to a bearing means, wherein the location of the processing facilities on the bearing means is structurally predetermined and the adjustment of the distances, in particular by replacing the bearing means by another storage means, which specifies a different distance of the processing equipment.

Furthermore, the processing apparatus may have various configurations of processing equipment. For this purpose, reference is made to the embodiments described below. Another special feature may be that the processing apparatus of a packaging machine for cigarettes is arranged upstream, in particular in the area of a bobbin trestle for providing or feeding the material web of at least one bobbin. An advantage of this solution is that the Scope of the processing apparatus is not limited by the space available in the packaging machine.

The invention relates to the production of blanks from a packaging material. The invention will be explained with reference to various examples of a collar 10 for a cigarette pack, for example of the Hinge-Lid type. In such packages, a collar 10 is arranged in a box part of the package so that it projects upwards out of the box part. Further, the package includes a lid which is pivotally hinged to the box part and which includes the collar in the closed position.

The variants of a collar 10 described below correspond to corresponding devices for producing such blanks, which will also be described accordingly. It is understood that the devices can of course be used not only in the production of collar 10 for cigarette packs, but also in other blanks. In this respect, the reference to the collar 10 is purely exemplary.

All embodiments have in common that the collar 10 are separated out of a continuous material web 11. This is done by a transverse separating cut. Furthermore, further processing steps can be carried out, which include in particular embossing, punching, punching, grooving, scribing the material web 11 or the collar 10. Also conceivable are processing steps such as printing, coating or the like. All processing steps are performed by appropriate processing facilities that are part of a processing apparatus 12. The construction of the processing apparatus 12 will be described later, after some examples have been explained in terms of the basic structure and the basic arrangement.

A first embodiment is shown in FIGS. 1 to 3. The collar 10 to be produced is shown in FIG. 3. The collar 10 has a collar front wall 13, and two lateral thereto arranged collar side walls 14, 15, which are arranged on both sides of the collar front wall 13. In the area of a collar top a recess 16 is formed. ^'In the area of a collar underside, a corresponding approach is 17. Since recess 16 and lip 17 have the same shape and dimensions, the collar can be separated out 10 falling freely from the material web. 11 Furthermore, the collar 10 has creases 18 or scratches in the longitudinal direction of the material web, which extend continuously over the entire length of the collar 10. Furthermore, the collar 10 in the region of the collar front wall 3 below the recess 16 on an embossment 19, and two C- or egg-shaped punching 20 laterally of the recess 16 in the transition between the collar front wall 13 and the respective collar side walls 14, 15th

The production of such a collar 10 takes place as shown schematically in FIG. Accordingly, a pair of feed rollers 21 is initially provided, between which the material web 1 1 is conveyed through in the direction of arrow 22. The material web 1 1 passes in this way in the working area of a knife roller 23 which cooperates with a counter-roller 24. In the area of the rotationally driven knife roller 23 all embossing, punching and separating cuts, as well as the groove 18 are attached to the collar 10. For this purpose, the knife roller 23 in the usual way on transverse knives, for separating the collar 10 of the material web 1 1 by means of a transverse to the longitudinal direction of the web of material 1 1 separating cut. The knife roller 23 has in the longitudinal direction of the material web 1 1 acting organs for forming the grooves 18. Further, on the knife roller 23 also has a stamping member arranged for attaching the stamping 19 on the collar.

The drive of the feed rollers 21 takes place in the present exemplary embodiment by means of a separate servo drive 25. The knife roller 23 is preferably coupled to the drive of the packaging machine. It is also conceivable that feed rollers 21 and knife roller 23 are connected by gearing, as in the following embodiments.

The second embodiment according to FIGS. 4 to 6 differs from the exemplary embodiment according to FIGS. 1 to 3 in that the collar 10 has a full-surface embossment 19. For this purpose, the feed rollers 21 are formed as embossing rollers, whereas the knife roller 23 must have correspondingly no embossing member, but only means for performing the separating cut and for attaching the creases 18 and punches 20th As mentioned above, the feed rollers 21 and the esserwalze 23 may be coupled by means of a gear 26 or the feed rollers 21 may be driven separately by a servo drive 25, as in the previous embodiment.

In a third exemplary embodiment according to FIGS. 7, 8 and 10, a collar 10 is produced, as in the exemplary embodiment according to FIGS. 1 to 3. However, the embossing 19 is not attached in the area of the knife roller 23, but in the region of an additional embossing roller 27 , which cooperates with a further counter-roller 24 and which is arranged between the feed rollers 21 and the knife roller 23. All rollers are coupled in this case via a common gear 26 with each other. Alternatively, it is of course again conceivable that the feed rollers 21 are driven by a separate servo drive 25.

A further alternative to the collar 10 according to FIG. 10 is shown in FIG. 9. The collar 10 shown there can also be produced with a device according to FIG. 8. However, the embossing roll 27 is not used in this case for the attachment of a locally limited embossment 19, but rather for the attachment of a partially full-surface embossment 19. Only a narrow strip-shaped area above the neck 17 is not embossed. In the next exemplary embodiment according to FIGS. 11 to 13, however, it is also possible to use a collar 10 or a material web 11 which has a print 28 applied before processing. The printing 28 is composed in the present case on the one hand of a print mark and on the other a decorative element which follows the contour of the collar top edge and is arranged at a small distance from the free edge of the collar top edge. Conceivable, however, are other decorative prints. Incidentally, the collar 10 is designed as in the exemplary embodiment according to FIG. 9, that is to say with a substantially full-surface embossment 19 which leaves only a narrow strip above the projection 17 free. The associated processing apparatus 12 initially has a pair of feed rollers 21, which are driven by its own servo drive 25. Downstream of the feed rollers 21 is a print mark reader 29. The print mark reader 29 is followed by a pair of embossing rolls 27 for attaching the embossment 19 and finally a knife roll 23 with counter roll 24. The embossing rolls 27 are connected to the knife roll 23 and the counter roll 24 by means of a gear 26th coupled. The device shown in Fig. 12 operates as follows: With the help of the print mark reader attached to the material web 1 1 imprints 28, in particular the print mark, scanned. In accordance with the position of the printing 28 or the print mark, the feed rollers 21 are controlled so that the embossment 19 is positioned to the print mark or the printing 28 in position. The non-embossed area or strip on the collar 10 thereby allows a control of the material web 11, because the material web 11 passes freely through the embossing rollers 27 in this area. In the area of the knife roller 23, the creases 18 and the punches 20 are finally attached and the transverse separating cut is carried out.

In the last exemplary embodiment according to FIGS. 14 to 16, a collar 10 is produced, which instead of embossing 19 of the exemplary embodiment according to FIG. 3 has a punching or perforation 30 at the same point. The perforation 30 is mounted in the region of a first embossing roller pair 27, which also serves to advance the material web 11. This is followed by a knife roller 23 with a counter-roller 24, in the region of which the grooves 18 are attached to the material web 11. In the area of a further knife roller 23 with mating roll 24, the transverse separating cuts for singling the collar 10 are applied.

The embodiments described above are intended to illustrate that for the production of collar 10 different processing steps are required, which can be done in the range of several processing stations or processing facilities. It shows, that Machining facilities may be configured to perform only one processing step or alternatively, the processing steps may be distributed to a single or multiple processing stations. FIG. 17 shows an overview of a device for producing such collars 10. Two bobbins 31 are shown, from each of which a material web 11 is pulled off and guided into a so-called collar apparatus 32. In the collar apparatus 32 is the processing apparatus 12 with the processing means described above.

The processing apparatus 12 is composed of processing devices as shown in Fig. 8, or for the production of collar 10 of FIG. 9. The processing apparatus 12 shown in FIG. 18 thus includes at a first position a pair of feed rollers 21 for conveying the web 11 through The processing apparatus 12 is then followed by an embossing roll 27 for attaching the embossment 19 to the material web 11. At the third position is followed by a knife roller 23 with longitudinal and transverse knives 33 for mounting the grooves 18 and for performing the cross-sectional cuts.

Fig. 19 shows a side view of the processing apparatus 12. Accordingly, a bearing means 35 is arranged on a machine housing 34, which is only partially shown, which is designed for mounting a plurality of processing devices 36, 37, 38 at predetermined positions. The positions are given in the present case by cross members 39. However, other constructional measures can also be implemented here in order to ensure that the positions of the processing devices relative to one another are predetermined by the bearing means 35. This facilitates the alignment of the processing equipment to each other.

In the present case, the first processing device 36 includes the feed rollers 21. In the middle, second processing device 37 is the embossing roller 27. In the third processing device 38 is the Knife roller 23 arranged, as well as a pair of accelerator rollers 40, for removing the isolated collar 10th

From Fig. 20 results in the construction of the transmission 26 for coupling the various processing devices 36, 37, 38. The various intake, embossing and knife rollers and their counter-rollers are rotatably mounted on shafts 42 respectively. The rotation of the roller pairs is respectively coupled by intermeshing gears 41 which are arranged intermeshingly on one side of the shafts 42 of the rollers. For the transmission of the driving forces 38 intermediate gears 43 are provided between the processing means 36, 37 and 37, respectively, which are in engagement with the gears 41 of the processing means 36, 37 and 38. The gears 41, 43 together form the gear 26 for coupling the various rollers together. Of importance is also the distance 44 between the processing devices 36, 37, 38. This distance 44 corresponds in each case to a multiple of the repeat length, ie the length of the material web 11 during one revolution of the respective rollers. If, for example, a change in the repeat length is required in the production of shorter collars 10, the spacing 44 between the processing devices 36, 37 and 38 must also be adapted. This is shown for example in FIG. 21. The intermediate gears 43 are mounted on pivot levers 45, whereby the position of the intermediate gears 43 is changed in reducing the distance 44 between the processing devices 36 without the coupling is interrupted by means of the transmission 26.

The adaptation of the distance 44 between the processing devices 36, 37, 38 is preferably carried out in that the bearing means 35 is exchanged for another storage means 35, which predetermines a corresponding position of the processing means 36, 37, 38. In this way, no or only a slight adjustment of the position of the processing devices 36, 37, 38 is required.
