Definitions

  • the present invention relates to a device for embossing and / or perforating films for tobacco products, comprising a pair of embossing rollers, wherein one of the embossing rollers has teeth for perforating the film, according to claim 1.

  • Prior art embossing devices with rollers are primarily used for embossing packaging films, e.g. for the food industry, the pharmaceutical industry and in particular for the tobacco industry.
  • devices with embossing rollers have been used for over 30 years for embossing packaging films, in particular so-called innerliners, these innerliners being provided not only with decorative effects but also with authentication features.
  • the paper content is stabilized such that the film can be processed without difficulty in the subsequent packaging system.
  • the term tobacco product manufacturing machine is understood to mean a device for wrapping individual pieces of tobacco products such as cigarettes, this machine being referred to in this application as "maker".
  • the embossed film can be direct or indirectly via a robot to the maker. Both methods are referred to as online methods. From there, the cigarettes get into a tobacco packaging machine, also called “packer” for short, in which a number of cigarettes are packed. In the present application, only the maker following the perforation is interested.
  • the perforations can be attached only in certain places, eg. B. outside the LIP zones, which cause the extinction of the cigarette after a certain time.
  • emphasis is placed on the fact that the film is not weakened in such a way by the perforations that a tearing of the same can be caused on further processing.
  • the long-known teeth are used in Pinup constellation, the teeth are disclosed as pyramidal.
  • the Wo application also discloses a control unit which inspects the film after embossing to determine various properties of the embossed film and to control the mutual pressure of the embossing rolls and thus the penetration depth of the teeth into the paper in terms of tear strength.
  • Fig. 1 shows a possible flow chart for the embossing and perforation of cigarette wrapping films, currently mainly made of paper or so-called Tippingfolien, hereinafter called "film”.
  • any embossing or printing patterns as well as the hole patterns must be placed in local dependency on these LIP zones. But even if the entire film is already completely treated with a fire-retardant substance, the possible embossing or printing patterns and the hole pattern must be generated at certain points. In this case, suitable marking, so-called “eye marks”, may already be present or be applied continuously. These zones, print patterns or other markings are detected by a position sensor. The various markings, patterns and zones on the film, if applicable, are summarized by the term "texture".
  • the film to be processed 1 first passes through a first position sensor 4, then optionally a known embossing unit 2 with here three embossing rollers 2A, 2B and 2C, then a synchronization unit 3 for detecting the relative position of the power stroke A1 of the embossing unit 2 with respect to the process cycle P. the maker. Subsequently, the film passes through a first buffer unit 7, a second position sensor 4A for detecting embossing and printing structures, a perforation device 5 and then a quality tester 6 for detecting the perforated pattern with pressure-regulating sensor 18, then via a second buffer unit 7A either directly or via a robot to get to the Maker not shown.
  • the embossing unit 2 may be a printer before, after or instead of switched, the control is analogous to the control of the embossing unit is formed.
  • the process cycle P can be defined, for example, by a length section of the film 1 to be fed per unit time of the maker, to which the working cycle A1 of the embossing unit 2 must be coordinated during the pretreatment of the film 1.
  • This corresponds to a positionally accurate arrangement of the impressed by the embossing unit surface structure on the respectively to be supplied longitudinal portion of the film.
  • the surface structures may be one or more logos created by removing or changing teeth on a roll or on multiple rolls. It can also be printed patterns.
  • the embossing unit 2 may also include a male-female embossing roller pair.
  • the synchronization unit 3 contains a determination device 8, this for example, a continuous optical detection of the position of the surface structure may have been imprinted in the embossing unit 2 on the film 1. The detection takes place on the transport path between the embossing unit 2 and the perforation device 5.
  • the determined working cycle 1 is adjusted in a positioning device 9 to the process cycle P.
  • a manual and / or automated adjustment method is conceivable.
  • the embossing roller of embossing unit 2 can be temporarily decoupled from the drive so as to extend the transport path of the film 1 by a desired amount, which is then in line with the process cycle P.
  • the need for extension of the transport path of the film is collected by a buffer unit 7, which is arranged behind the embossing unit 2.
  • the device additionally comprises a control unit 10.

  • electronic synchronizing signals or also mechanical synchronizing means may be used, such as a plurality of toothed wheels and / or belts, which may be equipped with an angle and / or position adjustment mechanism.
  • the information thus determined is further used in a positioning device 12 in order to adapt the working cycle A2 to the working cycle A1 such that the formed perforation patterns 25 have the desired relative position on the film 1E.
  • the positioning device 12 may be configured to manually and / or automatically adjust the circumferential relative position of the driven perforation roller 13 with respect to the film 1.
  • the markings 40 can serve on the embossing rollers.
  • a coupling for uncoupling the perforation roller 13 of the roller drive 15 is conceivable. This additionally allows a change in the relative position of the perforation pattern 25 on the film 1 as required or depending on the process.
  • the comparison device 11 can also be used to detect the relative deviation of the working cycle A2 from the process cycle P, for a renewed check of the synchronization with the subsequent enveloping 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 3 with the process cycle P.

  • the surface structures of the rolls are required in a greater variety, as well as more rationally and, more particularly, more precisely for a substantial improvement of the embossing possibilities and quality and, above all, for use in online processes can be produced. While the accuracy of the prior art could be ensured by etching or by mechanical processing with great effort, this does not apply to the rational and thus faster production of the male-die rollers in a wide variety of Perforationsorgane.
  • One solution is to form the surface structures of the rollers of a set independently of each other, ie, that not first the patrone roller and physically dependent on the die roller must be formed. At present, this is conceivable for the required precision and production time preferably when using a suitable laser system, which allows not only Patrizenwalzen but also to produce die rolls rationally, precisely and, above all, very in many different ways and independently of each other.

  • the time interval between the impact of the individual pulses can be chosen so large that a thermal overload does not occur.
  • the energy is applied in a very short period of time, allowing for so-called "cold ablation" where the material vaporizes rapidly without unacceptable heating of the adjacent material becomes.
  • the undesirable fluid state of the material, the crater edges and Generated splashes can be virtually completely avoided.
  • the desired structures are created on a computer that controls the laser system so that it does not matter if a surface structure is created for a punch roll or a die roll.

  • the lower embossing roller in the present case the die roller 14K, is pushed in or out for attachment and removal through a corresponding opening in the transverse side 52A and the axle end is rotatably mounted in the other transverse side 52B.
  • the storage by needle and ball bearings is known per se.
  • the male roller 13 is inserted from the rear invisible opening 53 and fixed in an accurate position.
  • this attachment is symbolically represented by a screw 54. Since it is a pair of male and female rollers, whose teeth or depressions are associated with each other, the two rollers must be mounted in a very precise relationship to each other in the housing.
  • One of the adjusting means in the direction of the longitudinal axis of the rollers is to produce two precisely aligned adjusting rings 55 on one of the rollers, here the die roller, and on the counter roller an exact central ring 56 which comes to rest between the two rings 55.
  • An adjustment possibility in the radial direction consists in the accurate production of the gears 31 and 32, which allow a very accurate radial positioning.
  • a pneumatic block 59 On the housing is a pneumatic block 59, which is controlled to precisely adjust the pressure and, derived therefrom, the distance between the two rollers.
  • the non-driven roller - here the upper roller - is mounted on its axes in such a way that it is possible to avoid the axes in all three coordinates. This makes it possible to precisely synchronize the teeth and recesses.
  • the connecting flange 58 of the axis of the lower roller is visible, on which the lower roller is driven.
  • the housing, the embossing rollers and the pneumatic block are the same, and the storage of the lower roller, the die roller, is the same.
  • the difference between the two embodiments lies in the storage of the upper, here the Patrizenwalze 13, this storage is shown very schematically.
  • the two ends of the axis 57, the upper roller 13 are inserted and secured in corresponding recesses 60 of two brackets 61, of the rear in the drawing.
  • the brackets can be moved in their length to adjust the distance between the two rollers from each other. This is symbolically indicated by the adjusting screws 62.
  • the upper roller may be stored such that their Axis is movable in the three dimensions.
  • the two rollers can be reversed, ie the male roller below and driven and the die roller above. This reversal of the position of the rollers also corresponds to the representations of FIGS. 21-36 ,
