Definitions
- the invention relates to an embossing rotary machine according to the features of the preamble of claim 1.
- Such rotary embossing machines are e.g. known from the following documents: US 5,486,254, WO 98 12 051 AI, DE 196 25 064 AI, DE 37 13 666 AI, EP 0 718 099 A2, EP 0 437 794 A2, DE 37 18 048 AI, DE 90 04 865 Ul.
- stamping foil sections are sections of a heat-sealing film with a structured or smooth surface, which may also have a hologram and which carry a thermally activated hot-melt adhesive on the back.
- stamping foil section When the stamping foil section is applied, it is glued onto the material web and at the same time transferred from the foil web or the remaining foil grid is pulled off from the glued portion.
- a pattern can also be embossed into the surface of the film during or after gluing.
- holograms can also be applied to material webs, in this case, in particular, with an exact temperature control of the Embossing tool and the stamping foil as well as an exact tension of the stamping foil must be ensured, otherwise the hologram will be destroyed.
- the feed of the stamping foil which is usually also an endless path, must be precisely controlled.
- the feed of the stamping foil is usually less than that
- the stamping foil section is applied must correspond to the imprint of the material web.
- the section of the embossing film to be embossed must be exactly aligned with the embossing stamp, so that the hologram is not destroyed on the one hand, and is transferred in the correct position on the other hand and is fixed on the material web.
- the invention is therefore based on the object of providing an embossing rotary machine in which on the one hand the embossing film and on the other hand the material web are treated gently and the transport speed of the embossing film can be set in a simple manner.
- This object is achieved with an embossing rotary machine which has the features of claim 1.
- the embossing rotary machine ensures that both the material web and the embossing film provided as an endless web are only transported in one direction and do not execute any oscillating movements, i.e. there is no change of direction.
- At least one embossing unit is located in the embossing device, which rotates in the opposite direction to the impression cylinder, with the complete supply of the embossing film being provided for this embossing unit in each embossing unit.
- the embossing film is transported via a transport device provided in the embossing unit in such a way that a new embossing film section is always provided, but the film waste is minimized. This can be done in a gentle manner, since this can be provided by slow feed.
- the provided stamping foil section receives the speed corresponding to the speed of the material web via the rotary movement of the stamping device, so that the section can be transferred from the stamping tool to the material web without any problems.
- the stamping foil is gently transported on and a new stamping foil section provided. It is important that the exact setting of the speed of the stamping film to the speed of the material web is made via the stamping device.
- the stamping foil itself is at rest during the stamping process within the stamping device.
- Fig. 2 a section II-II of FIG. 1, a first
- Fig. 3 a section II-II of FIG. 1, a second
- Fig. 4 a section II-II of FIG. 1, a third
- FIG. 1 Showing embodiment of an embossing device. 1 shows an embossing rotary machine, designated overall by 10, which has a machine stand 12 in which a drive shaft 14 for two embossing devices 16 and an impression cylinder 18 are rotatably mounted.
- the drive shaft 14 is coupled to a gear 20 and a drive 22.
- a suction device 24 is provided at the other end of the drive shaft 14, which is hollow, with which, for example, a waste film can be suctioned, which will be described in more detail below.
- FIG. 2 shows a section II-II according to FIG. 1, in which a first exemplary embodiment of the embossing device 16 is shown, which rotates in the direction of the arrow 68.
- the embossing device 16 has a disk-shaped carrier 26, on which a total of four embossing units 28 are arranged.
- the embossing units 28 are each offset by an angle of 90 ° to one another and are therefore arranged evenly distributed over the circumference.
- Each embossing unit 28 has a supply roll 30 for an embossing film 32, which is stored as an endless web on this supply roll 30.
- the embossing film 32 is pulled off the supply roll 30 by a first transport device 34 and transported in the direction of a winding roll 36.
- the embossing tool 40 is designed as an embossing stamp 42 which is mounted so as to be movable in the direction of the impression cylinder 18 and away from it.
- the two transport devices 34 and 38 each have a pull station 44, which is formed by two rollers, and a device 46 for keeping the tension of the stamping foil 32 constant.
- This device 46 has, for example, spring-loaded rollers, which ensure a constant tension of the stamping foil 32.
- a heating shoe 48 between the transport device 34 and the stamp 42, which heats the stamping foil 32 to a temperature e.g. heated between 80 ° and 120 ° C.
- a sensor 50 is located in the area of the heating shoe 48 or generally in front of the stamp 42, which optically, electronically, magnetically or touchingly scans a registration mark of the stamping foil 32 and by means of which the transport device 34 and optionally the transport device 38 are controlled.
- the stamping die 42 can also be designed to be heatable.
- the impression cylinder 18 can be heated or cooled.
- the direction of transport of the material web 52 is indicated by the arrow 54.
- the impression cylinder 18 accordingly rotates in the direction of the arrow 56.
- the transport direction of the embossing film 32 is thus opposite to the transport direction 54 of the material web 52.
- the embossing devices 16 are displaceable and adjustable in the longitudinal direction of the drive shaft 14. In this way, different material webs 52 or material webs 52 can be processed at different locations.
- the drive shaft 14 can be easily equipped with additional embossing devices 16, which are also fixed to it in a rotationally fixed manner.
- the material web 52 passes a printer control, which is indicated by the arrow 70.
- This printer mark control 70 or embossing control detects register marks of the material web 52 and controls the embossing stamp 42 and, if appropriate, the transport devices 34 and 38.
- a central disposal device 58 is provided, into which the waste film 60 of each embossing unit 28 is sucked in and discharged via the hollow drive shaft 14 and the suction device 24.
- This embodiment has the advantage that the embossing device 16 has a lower mass and that the embossing units 28 can be equipped with larger supply rolls 30.
- the embossing film 32 is driven by a conveyor belt 62, in particular a vacuum conveyor belt, the vacuum being provided via vacuum chambers 64 and 66.
- the vacuum chamber 64 has a heating device, via which the stamping foil 32 is preheated.
- the waste film 60 is sucked off centrally.
