Definitions

  • the invention relates to a device for the application of spatially limited, in particular flexible elements, e.g. B. Holograms or the like, on an endless web, which of a Supply roll pulled off, via a sealing station to one Trigger or guide station is transported, in which Sealing station the flexible element on the endless web is applied.
  • flexible elements e.g. B. Holograms or the like
  • cards, bills, sheets of paper or the like. be produced by first creating an endless web printed, punched, embossed, etc. is treated, and finally the individual products from the endless web be cut out or punched out. It is also known that these individual products also with limited space Elements, e.g. B. pictures, or very expensive holograms u. Like. are equipped. These spatially limited elements are in turn on an endless track from which lifted them off and applied them to the first endless web become. If the two endless tracks run with the same Speed through the sealing station, then only uses a fraction of the second endless path so that the predominant part of this second endless path as waste must be disposed of. This results from the fact that the spatially limited element is significantly smaller than that Products to which these should be applied. The Spaces between the individual spatially limited Elements on the second endless path must therefore be as Waste.
  • CH 365 259 A discloses a device in which an endless belt is withdrawn from a supply roll and wound onto a winding roll.
  • the invention is therefore based on the object To provide device with which the second Endless web can be used better, so the waste is reduced.
  • This object is achieved in that a device of the type mentioned before and after Sealing station an eccentric station is provided and the eccentric station has an eccentric shaft, via which the endless track is guided, the two eccentric shafts rotate 180 ° offset.
  • the eccentric shafts preferably run in the transport direction Endless loop around. In this way the Relative speed and thus the friction between Eccentric shaft and endless track reduced to a minimum.
  • the Eccentric shafts have a circular cross section and are stored eccentrically.
  • a circular cross section of the Eccentric shaft has the advantage that, contrary to one cam-shaped eccentric shaft, gentle on the endless track is treated because of the eccentric shaft outgoing forces rise or fall sinusoidally and thus abrupt force peaks can be avoided.
  • a reduction in frictional forces is achieved that on the eccentric shaft one versus the eccentric shaft rotatable sleeve supports, which in turn none Has relative speed to the transport path.
  • the Eccentricity of the eccentric shafts adjustable. In this way can the amplitude of the sinusoidal acceleration or Delay can be set to a desired value.
  • the Rotate eccentric shafts synchronously with the application cycle. always when a seal is to be made, the Transport speed of the endless track its minimum value on, which on the one hand achieves that sealing can be done with high precision, on the other hand, the first endless path has the same speed during the application, like the second endless web from which the hologram is removed.
  • the drawing shows a schematic view of the invention Device 10. From a supply roll, not shown is an endless web 14 in the direction of a take-off station 12 deducted from arrow 16. This continuous path 14 passes through first a first eccentric station 18 and then in a Seal station 20 performed, following the Sieglstation 20 performed via a second eccentric station 22 is transported by a further take-off station 12 becomes. With the reference numeral 24 are deflection or dancer roles designated.
  • a hologram film 26 is used in the sealing station 22 Hologram applied to the endless web 14. This is done via an embossing field, which is provided on a sealing roller 28 is.
  • the hologram foil 26 is, if necessary, not Transport device shown, from a supply roll 30th withdrawn and wound on a take-up roll 32.
  • the two eccentric stations 18 and 22 each have one Eccentric shaft 34 or 36 on an axis 38 or 40 circulate.
  • the two eccentric shafts 34 and 36 are of this type arranged that they are offset by 180 °.
  • the two eccentric shafts 34 and 36 rotate synchronously, whereby their offset by 180 ° is retained.
  • the Orbital velocity corresponds to Transport speed of the endless web 14 and so set that the two eccentric shafts 34 and 36 each of the endless web 14 located product once. This means that between the two eccentric stations 18 and 22 the section of the endless web 14 at each through the Sealing station 20 product once braked and is accelerated once.
  • the transport speed of the hologram film 26 is there set so that this is the minimum transport speed this between the eccentric stations 18 and 22 corresponding section of the endless web 14 corresponds, the application of the hologram at the time of minimal transport speed. Exactly this This is on the hologram foil 26 at the time arranged hologram exactly in the desired position the endless track 14. This is done with a register regulation reached, for which the hologram foil 26 has a register perforation has, in the corresponding transport or register pin or engage the sealing roller 28. After the application of the Hologram on the endless web 14 becomes the endless web 14 accelerates, whereas the speed of the Hologram foil 26 is retained. That way the distance between the individual holograms is reduced, so that the hologram foil 26 is better used and thereby the waste is minimized.
