An independent claim is also included for a device for producing a package for rod-shaped smoking articles.

Description

The present invention relates to a method and an apparatus for producing a packaging for rod-shaped smoking articles with at least one outer layer. By rod-shaped smoking articles cigarettes, cigarillos or cigars are meant. For the sake of simplicity, only cigarettes are usually mentioned below.

According to the prior art, a pack of cigarettes generally consists of an inner pack which can consist of paper, plastic, metallized paper or plastic paper, in rare cases also of an aluminum foil, as well as of an outer packaging made of a thin cardboard, as for example in the WO-2010/012370 A1 is described or may generally consist of plastic or of different layers of paper and plastic, granted sufficient mechanical protection and is provided with or without protective layer, which protects against drying and / or odor. In the above-mentioned PCT application, both the inner package and the outer package are each supplied as a blank to the packaging machine, where the cigarettes are wrapped by the inner package and pushed into the molded outer packaging.

In this case, the inner package, if it is a so-called innerliner, be embossed by known methods, ie provided with a satin finish and with logos. The feeding of both blanks synchronously with the cycle of the packaging machine requires a great deal of synchronization means, in particular if the inner packaging is embossed and / or printed.

Increasingly efforts have recently been made by governments and organizations to curb cigarette consumption, particularly among young people, and efforts are underway to promote advertising on cigarette packets; H. Both on the inner pack or inside as well as on the outer packaging completely inhibit or significantly restrict. In parallel, efforts are being made by the industry to streamline and reduce the cost of manufacturing cigarette packaging in terms of both material and manufacturing processes.

It is based on this known prior art object of the present invention to provide a method and apparatus for producing packaging for cigarettes, cigarillos or cigars, on the one hand meet the use of an inner packaging the various conditions that are placed on such packaging and on the other hand allow the packaging to be provided with a wide variety of visible or practically invisible, tactile, acoustical or olfactory sensible signs which may also serve as authentication features. In the context of this application, the term "sign" is understood to mean any type of lettering, individual points, point groups, colors and combinations thereof which are produced by the embossing roll (s) and can be detected visually, tactually, acoustically or via the sense of smell. This object is achieved by the method according to claim 1 and the device according to claim 7.

In Fig. 1 is a simplified flow diagram of a possible device for producing a package for cigarettes shown in the FIGS. 12 and 14 is shown. The device 1 according to Fig. 1 has a foil strip roll 2 with a foil strip 3, which first passes through an embossing unit 4, then a folding unit 5 and finally a cutting unit 6, in order then to arrive as a blank 19 to a packaging machine 7.

The packaging film, or the film strip 3, for producing an outer packaging, may be made of a lightweight material, for example paper, thin cardboard, hybrid films, d. H. multi-coated films of various materials or plastic films, which may be metallised or otherwise coated or, in certain applications, in certain countries where still permitted, a metal foil. In the following stands for simplifying the term "slide".

The device 1 has, as the first control unit 8, a synchronization device which serves to adapt the power stroke A1 of the embossing unit 4 to the process cycle P of the packaging process. The process cycle P can be defined, for example, by a length section of the film 3 to be supplied per unit time of the packaging machine, to which the working cycle A1 of the embossing unit 4 must be coordinated during the pre-processing of the film 3. This corresponds to a positionally accurate arrangement of embossed surface structures on the respective The length of the film 3 to be fed can be the surface structures which may be structures of the embossed characters 23S, 24S.

The synchronization unit 8 includes a determination device 9 for determining the power stroke A1 of the embossing unit 4. an optical detection of the position of surface structures 23 which have been impressed in the embossing unit 4 on the film 3. The detection takes place on the transport path between the embossing unit 4 and the folding unit. 5

The determined working cycle A1 can then be adapted to the process cycle P in a positioning device 10. For this purpose, a manual and / or automated adjustment method is conceivable. The driven roller may be temporarily decoupled from the drive so as to extend the transport path of the film 3 by a desired amount, which is then in line with the process cycle P. The extension of the transport path of the film 3 as required is absorbed by a first buffer unit 14 a, which is arranged behind the embossing unit 4.

For determining and controlling the working cycle A2 of the folding unit 5, the device 1 comprises a second control unit 11. The control unit 11 includes a comparison device 12, by which a detection of a quantitative deviation between the working cycles A1 and A2 of the embossing unit and folding unit is possible. This can be done, for example, by means of an optical representation by means of a lamp which is designed in the manner of a stroboscope for regularly spaced light irradiation on the film. The irradiation frequency corresponds In this way, the optical position of the relative position between the surface structures embossed in the embossing unit 4 and the fold breaks 21 ae formed in the folding unit 5 on the film 3, or the blank 19, takes place.

The determined information is further used in positioning device 13 in order to adapt the working cycle A2 to the working cycle A1 such that the formed folding fractures 21a-e have the desired relative position on the film 3. For example, the positioning device 13 may be designed for manual and / or automated adjustment of the peripheral relative position of the driven folding roller 34 with respect to the film 3. For this purpose, a coupling for decoupling the folding roller 34 from the roller drive 36 is conceivable. This additionally enables a change in the relative position of the fold breaks 21 a-e on the film 3 as required or as a function of the process.

The comparison device 21 can also be used to detect the relative deviation of the working cycle A2 with respect to the process cycle P, for rechecking the synchronization with the subsequent packaging process. Furthermore, indirect conclusions can be obtained in this way on an unwanted deviation of the power stroke A2 with respect to the power stroke A1, since the power stroke A1 is already synchronized by means of the synchronization unit 8 with the process cycle P.

To demand extension of the transport path of the film 3 at an intervention of the positioning device 13 is after the folding unit 5, a further buffer unit 14b is provided.

The second control unit 11 is adjoined by a third control unit 15 in order to synchronize the power stroke A3 of the cutting unit 6 with the process clock P. Analogously to the second control unit 11, the third control unit 15 comprises a comparison unit 16, by means of which a detection of a quantitative deviation between the working cycles A2 and A3 of the folding and cutting unit is made possible. Analogous to the second control unit, the signals can be detected. The information thus determined is further used in the positioning device 17 to adapt the power stroke A3 to the power stroke A2 such that the cuts 22a-22f have the desired relative position on the blank 19.

The foil strip 3, 3b can be preprinted or unprinted. However, it is also possible to provide a printing unit in front of the embossing unit in order to print in the process cycle P the film strip. The control unit provided for this purpose is similar to the described control units in order to synchronize the power stroke of the pressure unit with the power stroke of the other units and with the process clock. In the device, a station for applying odors can be integrated, with a further control unit ensures that this station operates in the process cycle P.

In the subsequent packaging machine 7, the blank 19 equipped with fold breaks 21 a is fed continuously to the packaging machine in the process cycle P. There is a direct folding of the blank 19 to be packaged cigarettes 18. In this case, thanks to the folding fractures 21 ae only a small force required, thereby Destruction of the packaged goods is effectively avoided. The fold breaks 21 ac are preferably arranged at the bottom of the packaging thus formed, where two folds along the folded edges are performed. In the FIGS. 9-11 this process is shown schematically.

In Figure 1C a wider foil strip 3b is shown to receive the cigarettes in landscape format. The film strip 3b is embossed, folded and cut similarly to the film strip 3 to give the blank 19b with the embossed marks 24S, the fold breaks 25 and the cuts 26. Of course, both the embossing unit and the folding and cutting unit are adapted to the width of the film strip.

In certain applications, or film nature, it is not necessary to fold the film strip before wrapping, so that the folding unit is not used and the control units are adjusted accordingly. In other applications, it may turn out that the embossing of the film strip is not required and the film strip passes from the film strip roll directly to the folding unit. Also in this case, the control units are adjusted accordingly.

The number and design of the rollers of the embossing unit 4 largely depends on the nature of the film strip and on the desired type of embossed characters. In the case of inner liner resembling films, one side of which is metallised or similar, known embossing rollers can be used which are described in numerous patents and applications of the same applicant, eg in US Pat WO 02/07671 defined and in the FIGS. 2 and 3 are shown. These are rollers in a pin up - pin up constellation, whereby the characters thereby arise that teeth are removed completely or partially on the embossing roller. Arrangements with two or three rollers are described, but the arrangements can also have more than three rollers.

The rollers with characters and possibly with isolated teeth are defined as embossing rollers, while the other rollers, whether via synchronization means or driven directly or indirectly, are defined as counter-rollers. However, this does not exclude that more than one roller of a device may have characters and thus embossing rollers. In addition, it is assumed that the film strip is always performed in the same orientation with respect to its outer side between the rollers.

The embossing arrangement 4A shows three rollers, an embossing roller 53 driven by a drive 27 and a first counter-roller 32 and a second counter-roller 33, the two counter-rollers neither being directly driven nor connected to the driven roller via synchronization elements, e.g. Gears are synchronized, but are driven only via the foil strip 3.

In deviation from the great majority of previously known roller arrangements, the three rollers do not have the same structure. While the driven embossing roller 53 has teeth 31, the first counter roller 32 is provided with rings 32R running around the entire periphery and arranged in parallel with each other such that the teeth 31 of the embossing roller 53 engage in the grooves between the rings. The rings 32R are tapered outwardly and flattened so as to engage between the teeth 31.

The second backing roll 33 has longitudinal ribs 33L which, like the rings 32R, taper outwardly and are flattened such that the longitudinal ribs 33L cooperate with the teeth 31 of the embossing roll 53. The rings or longitudinal ribs can influence the appearance of the embossing pattern produced by the embossing roller with teeth. With such embossing roller assemblies, it is possible, by varying the teeth 31 or the rings 32R or the longitudinal ribs 33L, i. by changing the height, flanks or edges of the teeth, rings or longitudinal ribs or patterning of their upper surface produce various embossing patterns or characters and, if appropriate, better break the nerves of the film paper.

The roller assembly 4B has the same drive 27 and the same driven embossing roller 53 and a counter-roller 29 with teeth 31. The logos 23L were obtained by removing or modifying the teeth 31 at these locations.

In the case of packaging films which are not metallized and which should also have tactile or acoustic characteristics where appropriate, rollers are suitable in which only teeth are present where the logo is to arise and wherein the teeth are preferably arranged on the non-driven roller.

In the FIGS. 4 to 7 four further versions of the embossing unit 4 are shown. The embossing arrangement 4C according to Fig. 4 assumes a pin-up-pin-up configuration which is proven for embossing inner liners, in which all three rolls 28, 29 and 30 have teeth 31 projecting from the surface of the roll cylinder, in which case one tooth of a roll is interposed between four teeth of the other rolls intervenes, whereby a self-synchronization is achieved and the embossing more precise and the drive is simplified. The first roller 28 is driven by a symbolically represented drive 27, wherein the drive can also be a motor.

According to Fig. 4 three rolls are used for the embossing of the film strip 3. The drive roller 27 driven by embossing roller 28 includes embossing lines 23, 23A and at the two edges rows of teeth 52 to better transfer the driving force to the counter-rollers and to protect the embossing roll from dozing, if there are only a few embossing lines or embossing rows. Embossed lines or rows are understood to mean rows or rows on which any characters formed from teeth 31 are arranged. The counter rollers 29 and 30 have only teeth 31 here.

In contrast to the embossing rollers according to the FIGS. 2 and 3 For example, for embossing inner liners, when embossing outer foils on the corresponding embossing roll, only teeth are present where characters shaped therewith are to be embossed. If necessary, the teeth of the counter rolls serve to break the nerves of the paper.

When satinizing and simultaneously embossing characters on innerliners, the metallized surface of the packaging film is stamped so that in almost all cases the driven roller has the indicia, while in embossing outer films it may be advantageous to attach the indicia to one of the non-driven embossing rollers to get on the slide positively outstanding characters, as in FIG. 5 is shown. As a result, both tactile and acoustically effective characters can be generated. In the embossing assembly 4D, one of the two non-driven rollers is the embossing roller 30A having the embossing lines 23, 23A.

This may also apply to the case in which the embossing arrangement 4E has only two rolls, as in FIG Fig. 6 in which said embossing assembly 4E comprises a driven roller 28F and an embossing roller 29A driven therewith with the embossing lines 23, 23A. In the illustrated case, the embossing roller 29A has a double circumference of the driven roller 28F.

In the embodiments, the teeth 31 are shown in a pyramid shape with a square outline, wherein the tips can be flattened up to 25%. However, a number of other pyramidal teeth having a variety of other layouts and shapes are known, e.g. pyramidal teeth of rectangular outline, e.g. in the direction of the longitudinal axis have a greater length of its base than in the other direction. For certain applications in which the counter rolls are driven by synchronization means, it may also be frustoconical or conical teeth. The teeth can be pitched, i. a distance between the tips, from 0.05 mm to 0.4 mm, at a theoretical height without flattening of 0.03 mm to 0.3 mm. Furthermore, individual teeth or groups of teeth may be designed differently as known in the art.

In FIG. 7 For example, an embossing assembly 4F is shown having a similar roll configuration as FIG Fig. 2 shows, wherein the driven embossing roller 28 cooperates with a first counter-roller 32 with rings 32R and a second counter-roller 33 with longitudinal rips 33L. In contrast to the execution according to Fig. 2 has the embossing roll 28 only there teeth 28 where embossing rows or rows 23, 23A are provided.

With the embossing rollers described and further known per se, it is possible to characterize characters that appear to the eye as patterns, colors, color patterns or are almost invisible, serve as authentication features, tactile detectable or can generate acoustic signals.

In the Figures 2 . 4 . 5 or 7 It is suggested that both mating rolls are engaged with the embossing roll, but this is not necessarily always the case. It is also conceivable that the first or second mating roller is only engaged with the first or preceding roller or can be brought into engagement. In addition, it may be advantageous to provide more than a total of three rollers for certain applications, which have a different surface structure. Furthermore, both the diameter and the length of the individual rolls may be different. In addition to the metal rolls, soft rolls can also be used.

In FIG. 8 1, a roller assembly 4G is shown in a so-called pin-up-pin-down configuration, with the raised embossing elements 23R on the driven roller 54 and the corresponding hollow embossing elements 23H on the counter roller 55. The drive of the counter roll via a synchronization gear 56, 57. In the sectional figure 8A, the elevations 23R and the recesses 23 H are illustrated.

In the FIGS. 9 and 10 a possible arrangement of a folding unit 5 is shown. This folding unit comprises two folding rollers 34 and 35, wherein the folding roller 34 is driven by a drive 36. The second folding roller 35 is driven and synchronized via a synchronization gear 41 and 42. The two folding rollers are essentially smooth and have complementary structures to each other to achieve the desired fold breaks. The folding roller 35 has both circular rings 37 and longitudinally arranged ribs 38 a - e, which engage in corresponding circular grooves 40 and longitudinal grooves 39 a - e of folding roller 34.

It is possible to additionally provide embossing elements on the folding rollers, z. As teeth or groups of teeth that can be arranged on one or both rollers, as in the Figures 2-7 , or Prägelemente according to the roller assembly of FIGS. 8, 8A , wherein the raised embossing elements 23 R are arranged on the folding roller 35 with the folding tools and the hollow embossing elements 23 H on the other folding roller 34.

In this case, both the shape and the cross sections and dimensions of the rings or ribs or grooves may be different depending on the material to be folded. In Fig. 10 , a side view of Fig. 9 , The interlocking of the longitudinal ribs and longitudinal grooves is shown.

In Fig. 11 a possible arrangement of a cutting unit 6 is shown. This consists in the present case of two cutting rollers 43 and 44, wherein the cutting roller 43 is driven by a drive 45 and via a synchronization gear 46 and 47, the second cutting roller 44 drives. The first cutting roller 43 is smooth in the present example, while the second cutting roller 44 cutting blades 48 and 49 a - e, which are formed, the blank 19 according to Fig. 1A or 1B to cut. The cutting rollers can also be provided with stamping teeth and / or embossing elements like the folding rollers.

Both the folding rollers and the cutting rollers may have means to prevent their buckling, which means e.g. Rings or teeth can be.

In the FIGS. 12-14 schematically the operation of the packaging machine 7 is shown. In Fig. 12 is the folding of blank 19 for receiving the cigarettes 18 shown and in Fig. 14 the finished package 20. Optionally, the cigarettes in a holder 50 according FIG. 15 held together and / or in an inner liner 51 according to FIG. 16 which then fits into the pack 20.

As can be seen from the description, this device is particularly suitable for the on-line production of smoking article packaging, from roll on the film strip optionally printed, embossed and / or folded and then cut and the blank is folded, filled and wrapped around the cigarettes and all this in time with the packaging machine. In addition, the online processing of thin cardboard, paper or plastic by the folding and breaking of the nerves by the counter roll (s) is facilitated or even possible. In the device, an odor unit can be integrated, which applies in the on-line process odors before folding. From the description of the rollers it is clear that any combination of embossing, folding and cutting elements on rollers is possible.

Since all units work in time with the packaging machine, in particular the folding and cutting does not require any additional positioning means, because the packaging blank is synchronized directly from the roll, embossed, folded and cut.

In the description, it has been assumed that a device which processes either an outer or an inner packaging, but it is possible to use at least one further device online, so that processed both a foil strip for the outer and a foil strip for the inner packaging be such that both film strips are folded in the packaging machine so as to give a two-layer packaging. For this purpose, the control units are equipped accordingly to ensure the necessary synchronization with the power strokes and the process cycle.
