Definitions

  • the invention relates to a device for printing rigid workpieces with a pattern, preferably with a woodgrain decor, with a transport device for the workpiece and a printing device which has at least one application roller acting on the workpiece. Furthermore, the invention relates to a method for printing rigid workpieces.
  • a device for printing flat wood-based panels which are provided for example with a woodgrain decor.
  • the device comprises a printing station, in which the workpiece is fixed during the printing process, a printing device movable relative to the printing station with a plurality of individually digitally controllable inking elements and a control unit for driving the inking elements and the relative movement between the printing device and the printing station.
  • the inking elements are distributed in at least one row over the entire working width.
  • transfer printing methods are also known in which the actual printing roller first transfers the image or the pattern to an applicator roll, from which the printing takes place on the workpiece.
  • the pressure roller can be designed, for example, as an engraved or etched steel roller, to which the applied paint adheres to the engraved or etched points.
  • Such an embodiment is for example from the DE 103 33 626 A1 known.
  • the above-mentioned device are suitable for flat, plate-shaped workpieces, but not for structured or profiled strips.
  • a device has become known with which arched or profiled wooden strips are printed directly digitally.
  • the ink jet and the laser method are called.
  • the strips are used for the production of blind elements, which are provided with a wood pattern decor.
  • this direct printing method on a profiled surface, however, great inaccuracies of the pattern representation must be expected, since the print head can not be adapted to the different profile geometries or only with great effort.
  • the object of the invention is to propose an apparatus and a method for printing profiled surfaces, wherein pattern images, in particular wood grain replicas are to be applied with high imaging accuracy.
  • the applicator roll for printing structured or profiled surfaces of the workpiece has a soft set surface and that at least one digital printhead is provided for the pattern application to the applicator roll.
  • the in the Fig. 1 and Fig. 2 illustrated device is used for printing structured or profiled surfaces of a workpiece 1, for example, a decorative or skirting board, with a woodgrain decor.
  • the apparatus comprises a transport device 2, for example a conveyor belt or an arrangement of support rollers, and a printing device 3, which comprises a transfer roller 4 and a digital print head 6.
  • the digital printing of the pattern is first carried out at a constant, constant gap to the print head on the soft surface 5 of the transfer roller 4 and is then transferred with great accuracy to the profile contour 10 of the workpiece 1.
  • the digital imprint of the pattern on the surface 5 of the applicator roll 4 as a function of the profile contour 10 of the profiled workpiece 1 distorted (in some areas stretched or compressed) and so on the different effective radii r1, r2, ..., in the Transmission of the pattern on the profiled workpiece 1 can be adjusted.
  • a preferably optical scanning device 9 can be arranged in the direction of movement of the workpiece 1 in front of the application roller 4.
  • the digital printhead 6 can be embodied as an inkjet printhead or laser printhead and preferably have a width which corresponds to the width of the application roller 4. It can also be arranged several print heads to order different colors in a row.
  • the axis 4 'of the application roller 4 in a range of 0 ° to 20 ° to the plane ⁇ of the transport device 2 can be designed to be pivotable.
  • a drying device 8 preferably a UV dryer, may be arranged in the direction of movement of the workpiece 1 after the applicator roll 4.
