Definitions

  • the invention relates to a device for applying a coating medium to at least a partial surface of an elongate workpiece which is transported in its longitudinal direction, consisting of a coating chamber which can be subjected to vacuum and has an inlet die and an outlet die, a coating frame and an outlet guide arranged in front of the outlet die.
  • the coating chamber is provided for the passage of the workpiece with an inlet die and an outlet die, both of which are adapted to the cross section of the workpiece, but are designed to be larger by a predetermined amount, so that a circumferential, constant gap is present between the surface of the workpiece and the dies , Air is sucked in from the outside via the gap in the inlet die and in the outlet die, so that a vacuum of the desired size is established in the coating chamber.
  • a coating frame is provided which has either several bores or several flat jet nozzles, through which the coating medium is sprayed onto at least part of the surface of the workpiece.
  • the invention is based on the object of demonstrating a device for applying a coating medium on at least one partial surface of an elongated workpiece which is transported in its longitudinal direction, in which a more uniform and constant application of the coating medium is achieved without additional effort, which is still effective even at higher production speeds allows very good quality of the coating.
  • the mask that was previously required is to be dispensed with.
  • the coating frame is designed as a flat nozzle and is arranged between the outlet guide and the outlet die.
  • the coating chamber can be made shorter, so that smaller application units result.
  • the application of the coating medium can be better controlled and the bead of coating agent that arises at the end of a workpiece can be reduced.
  • the coating frame is either connected to the outlet guide or integrated in the outlet guide.
  • Coating chamber 3 shown, which is connected to a vacuum line 4.
  • This coating chamber 3 has on the one hand an inlet die 5 and on the other hand an outlet die 6, the cross section of which corresponds to the cross section of the workpiece 2 but is slightly larger on all sides, so that a gap 7 of predetermined size extends around the workpiece 2 on all sides. Air is drawn in from the outside via column 7 due to the vacuum applied to the coating chamber 3. Due to the size or the cross section of the column 7, a vacuum of a predetermined size can now be achieved in the coating chamber 3.
  • a channel 9 is located in this outlet guide 8, which is supplied with a coating medium, for example paint, via a line (not shown in the drawing).
  • a coating medium for example paint
  • a line not shown in the drawing.
  • a so-called flat nozzle 10 leads outwards in the direction of the workpiece 2.
  • the coating medium is now applied or sprayed onto at least part of the surface of the elongated workpiece 2. Due to the fact that the application of the coating medium - seen in the transport direction of the workpiece 2 - takes place behind the outlet guide 8, no defects in the coating on the workpiece 2 are generated by the latter.
  • the coating is now applied to the workpiece 2 in the transport direction. Excess coating medium is entrained by the air sucked in via the gap 7 in the outlet die 6. As a result of this configuration, the coating medium reaches the workpiece 2 at all the provided locations, so that defects in this regard are also excluded.
  • the coating frame designed as a flat nozzle 10 is integrated in the outlet guide 8, it can also be designed as a separate frame which is either connected to the outlet guide 8 or is arranged as a separate component between the outlet guide 8 and the outlet die 6.
