Definitions

  • the invention relates to a device for multicolor printing of thermoplastic film webs with a plurality of printing units connected in series and at least one drying device arranged between adjacent printing units, in which the freshly printed ink is dried by supplying air.
  • What is essential for multicolor printing on thermoplastic film webs is the precision of the repeat, ie the exact coverage of the printed images which are transferred from the corresponding printing units, in particular printing rollers, to the film web.
  • the film web itself is the cause of malfunctions. If the film web has been produced with a drawing calender, the web always has a thickness profile as a result of the rolling out, which profile is formed in accordance with the deflection and the roll shape. This thickness profile multiplies when rolled up into a roll.
  • thermoplastic film web is fed to a heating and cooling cylinder combination before printing.
  • the film web which is pressed onto a heating cylinder with a rubber roller, is heated and then cooled via a downstream cooling cylinder.
  • the film leveled in this way is then fed to the printing device.
  • the invention has recognized that the cause of this disturbance must be sought primarily in the area of the drying devices, because in the area of the drying devices air is blown at room temperature or at a higher temperature onto the printed side of the film web in order to dry the freshly printed inks.
  • the film also heats up and a shrinking process occurs in which the cross section of the film again approximates the original thickness profile.
  • the object of the invention is therefore to improve compliance with the repeat in multicolor printing of thermoplastic film webs.
  • each drying device has a cooling surface for the non-printed side of the film web and that the drying air is blown in the direction of the cooling surface.
  • the heat absorbed by the film web in the area of the drying device is immediately dissipated via the cooling surface.
  • the film web cannot therefore heat up and consequently no shrinking processes can be initiated.
  • the film web maintains its leveled shape or cross-section and can accordingly be printed with an exact repeat in the downstream printing units.
  • a further advantage has been shown that the cooled or supercooled film web is less stretchable, so that the constriction in width which inevitably occurs under the influence of the longitudinal tension required for printing is considerably less.
  • the device according to the invention is advantageous both in the longitudinal repeat and in the transverse repeat.
  • the cooling surface expediently consists of a sliding table with cooling channels arranged in the guide plane of the film web.
  • the cooling channels can be formed by profile sheets arranged on the back of the sliding table and connected to a cooling system with a heat exchanger and circulation pump. Other arrangements and configurations of the coolant channels are possible.
  • a functionally advantageous embodiment is characterized in that a plurality of nozzles for the supply of dry air are arranged opposite the cooling surface. Then the impulse of the air jets can also be used to press the film web against the cooling surface or the sliding table. The impulses of the air jets are usually so large that the film web even then is pressed against the cooling surface when the cooling surface is directed downwards and the nozzles are arranged below it. As a result, the function of the drying device is largely independent of its respective spatial arrangement.
  • the drying device with the cooling surface can be arranged essentially horizontally or at an angle to the horizontal or essentially vertically.
  • a preferred embodiment is characterized by two drying devices arranged next to one another and connected in series, through which the film web is first guided upwards and then downwards again, or vice versa, before it runs into the next printing unit.
  • the drying device can also have a plurality of cooling surfaces arranged in different planes, in particular a vertical and then a horizontal cooling surface.
  • each drying device in a housing, one wall of which forms the cooling surface.
  • the device shown in the figure is used for multi-color printing of thermoplastic film webs 1 with a plurality of printing units connected in series, of which only two printing units 2, 3 are shown in the drawing.
  • the printing units 2, 3 are constructed identically, so that it is sufficient to describe only one printing unit.
  • Each printing unit has an ink tray 4, in which a printing roller 5 is partially immersed.
  • the pressure roller 5 has a drive, not shown.
  • Each pressure roller 5 is assigned a press roller 6. which is arranged above the pressure roller 5 in the illustrated embodiment.
  • the film web 1 is drawn into the nip between the pressure roller 5 and the press roller 6 and printed on it. After printing, the film web 1 passes into a drying device 7, which is enclosed by a housing 8, which has an inlet slot 9 on one side and an outlet slot 10 for the film web 1 on the opposite side.
  • the housing 8 is box-shaped and has an essentially horizontal partition 11 with a plurality of nozzles 12 arranged therein.
  • an inlet connection 14 for the supply of air at room temperature or at a higher temperature.
  • the supplied air is blown through the nozzles 12 onto the currently printed side of the film web 1 and is intended to dry the freshly printed ink. Used air is drawn off via an outlet connection (not shown).
  • the upper wall of the housing 8 is designed as a cooled sliding table 15.
  • the sliding table 15 has a cooling surface 16 directed downwards, against which the film web with its unprinted side is pressed under the action of the air jets.
  • a plurality of profiled sheets 17 are attached, which form cooling channels 18, which are connected to a cooling system, not shown, with a heat exchanger and environmental pump.
  • the drying device 7 can be arranged not only with a horizontal cooling surface as in FIG. 1 but also with a cooling surface inclined to the horizontal (FIG. 2).
  • FIG. 3 the drying device 7 has both a vertical and a horizontal cooling surface. After all, you can.
  • Arrange drying device 7 also vertically, as shown in Figure 4. In this case, the embodiment shown in FIG.
