Definitions

  • the invention relates to a device for applying a coating medium to at least one partial surface of an elongate workpiece which is transported in its longitudinal direction, ' ; consisting of a coating chamber to which a vacuum can be applied, each having an opening formed in the inlet and outlet walls of the same and adapted to the cross section of the workpiece, and a slot nozzle located in the coating head and capable of being coated with the coating medium.
  • this opening is slightly larger on all sides, so that there is a continuous, constant gap between the boundary edges of the opening and the workpiece.
  • a workpiece can have transverse grooves, transverse grooves, holes or blind holes between its ends.
  • the outlet opening that is to say the opening at which the coating medium is already on the workpiece
  • there is a considerably larger gap in the outlet opening around the workpiece through which the volume flow and the speed of the intake outside air change.
  • the thickness of the coating medium changes or increases in such areas.
  • This accumulation of the coating medium can lead, for example, to a non-functional coating which is associated with cracks and / or color changes.
  • the invention is based on the object of demonstrating a device for applying a coating medium to at least one partial surface of an elongated workpiece which is transported in its longitudinal direction, in which the change in the speed and volume of the air sucked in from the outside caused by a reduction in the cross section of the workpiece does not occur noticeably affects the thickness and quality of the applied coating without the need for special nozzles and air flows with appropriate controls.
  • the device according to the invention Genre described in the introduction proposes that at least the outlet-side wall in the region of the opening extends at an acute angle transverse to the transport direction of the workpiece.
  • the air sucked in from the outside no longer flows in the reduced-cross-section areas in the direction of transport of the workpiece, but over the reduced cross-sectional areas, so that the desired coating quality is achieved in these areas without additional effort.
  • No thickening or beading occurs at the ends of the workpiece.
  • Excess coating medium is also sucked off in the slot and tenon areas in the same way as at the other points. No additional effort is required to achieve these advantages.
  • the device is space-saving since there are no additional nozzles with lines and control elements.
  • FIG. 1 only one coating chamber 3 of a device for applying a coating medium to at least one partial surface of an elongate workpiece 2, which is transported in the longitudinal direction according to arrow 1, is shown, which is connected to a vacuum line 4.
  • This coating chamber 3 has an opening 6 both on its inlet-side wall and on its outlet-side wall 5. Only the outlet-side opening 6 can be seen in the drawing. Both the inlet opening and the outlet opening 6 can be formed in an interchangeable template which is inserted into the wall 5.
  • the cross section of the outlet-side opening 6 is adapted to the cross-section of the workpiece 2, but the cross-section of the opening 6 is larger on all sides by a predetermined amount than the cross-section of the workpiece 2.
  • the air sucked in via the gap between the workpiece 2 and the opening 6 does not flow exclusively in the longitudinal direction of the workpiece 2. Rather, it flows when one end of the groove 7 first reaches the region of the opening 6. Air drawn in through this groove 7, which also entrains excess coating medium in this area, so that the desired, uniform application of the coating medium is also achieved here.
  • inlet-side wall 5 - as indicated by dashed lines - and the opening 6 arranged there at an acute angle transversely to the transport direction of the workpiece 2.
