Definitions

  • the invention relates to a device for painting or coating a sheet by means of a rotating application roller, which cooperates with a counter-pressure roller, on which the sheet is guided and coated, and with a suction roller in the form of rotating, perforated hollow rollers connected to a suction source.
  • the comprehensive removal device for sealingly sliding against an internal open suction chamber for pulling the sheets off the application roller.
  • a coating device of the type mentioned at the outset has already become known in British Patent Specification 446 558, in which an attempt is made to detach the coated sheets adhering to the application roller in that the counter-pressure roller is designed as a perforated hollow roller which seals on an internal open suction chamber.
  • a moisture film should also be applied to the outer surface of the hollow roller in order to increase the adhesion of the sheet initially adhering to the application roller to the counter-pressure roller, so that the sum of this adhesion to the liquid film and the suction effect on the sheet removes this from the application roller .
  • the invention is therefore based on the object of designing a coating device of the type mentioned in such a way that at high working speeds a clean and safe detachment of the sheet from both the application roller and the counter-pressure roller is possible without the sheet edge being damaged or the machine becomes unnecessarily dirty.
  • the invention provides that the suction rolls are arranged in the nip behind the applicator roll and its counter-pressure roll in the deflection area between transport belts used for further transport of the sheets, these transport belts in turn preferably being designed as suction belts moved over suction boxes.
  • a further improvement in sheet removal and transfer to the conveyor belts can be achieved according to a further feature of the invention in that the suction rolls with a Coating with a high coefficient of friction, especially rubber, are provided.
  • suction rolls can be connected to the suction source independently of one another, a very simple adaptation to changed sheet formats can be achieved without having to convert the device.
  • the individual suction rolls are easily exchangeable or removable, for example with simple quick-release fasteners, so that a suitable width of the suction roll arrangement can be set when the format is changed.
  • the actual coating device with an inking roller 1, an intermediate roller 2, the application roller 4 and the counter-pressure roller 5 can only be seen schematically, the sheets 7 introduced along the path of the arrow 6 running between the counter-pressure roller 5 and the application roller 4.
  • the take-off device for the sheets comprises, in a manner known per se, suction belts 8 with suction openings 9 which are arranged above suction boxes 10. The sheets 7 resting on the suction belts 8 are thus held by suction on the suction belts, so that slipping of the sheets and a disturbance of the removal are reliably prevented even at high processing and transport speeds.
  • suction rollers 11 in the front deflection area of the conveyor belts 8 are arranged between these suction rollers 11, which can be switched on or off and off on the application roller 4 by actuating devices (not shown in detail because such coating devices are known per se), the starting and stopping being preferred can be controlled automatically via the function button of the system.
  • the suction rollers 11 shown in greater detail in FIGS. 3 and 4 comprise perforated hollow rollers 12 which slide sealingly on an inner open suction chamber 13.
  • FIGS. 3 and 4 denote the front and rear deflection rollers of the conveyor belts 8 and 24 the tensioning rollers for the conveyor belts 8, while at 23 in FIGS. 3 and 4 crossbeams are designated, on which the boxes 16 with the connecting lines 17 to the suction source and thus the suction boxes themselves are held. For the sake of clarity, these cross members 23 are not shown in FIG. 2.
  • the suction rollers 11 and the suction belts 8 each receive their drive via the shaft 19, specifically once via the toothed gears not specifically identified, and secondly via the transmission belt 25.
