Definitions

  • the invention relates to a device for applying a Coating medium on at least a partial surface of an elongated and in its longitudinal direction transported workpiece, consisting of a with Vacuum applied coating chamber with at least one coating unit, from each one of the coating chamber upstream and downstream Roller conveyor and from acting in the coating chamber Transport means.
  • DE-PS 36 15 750 is a so-called puncture device for workpieces Known in the field of coating chambers, where a pressure cam on the free end of a carriage connected to a push rod is arranged. This pressure cam is laterally movable in the movement path of the workpieces. The slide is in turn guided on a long-cylindrical slide bar and is from the same limited transversely to the direction of rotation recorded. Of the entire movement mechanism of such a piercing device is relatively expensive. In addition, the distance between two be formed relatively large successive workpieces. The Operating speed of the known piercing device is relatively low.
  • the invention is therefore based on the object, a device for applying a coating medium on at least a partial surface of an elongated and to provide in its longitudinal direction transported workpiece, the in time before the occurrence of feed problems for a continuous Transport of workpieces through the coating chamber ensures higher transport speeds permits and in which the distance between two successive Workpieces can be reduced to a minimum.
  • the transport device at least one in front of the coating chamber in the trajectory and behind the coating chamber from the movement path of the workpiece can be brought
  • Cam is that the cam at one through a slot in the Coating chamber protruding arm is attached and that the arm with at least a circumferential and a drive associated chain is connected.
  • Such a device has a relatively simple and without large Effort to be produced structure.
  • the device dispenses with a "push-to-push operation" of the workpieces in the coating chamber leaves higher Transport speeds of the workpieces to and the distance or the gap between the individual workpieces can be reduced to a minimum.
  • Around Cycle times on demand can be two or more arms on the chain be attached with cams.
  • the contact surface between workpiece and cam can be relatively low, so no significant impairment a coated end face of the workpiece occurs.
  • a coating chamber 1 first of a coating chamber 1 is only one Wall 1a shown in the elongate workpieces 2, for example profiled bars made of wood, with a coating, for example with a glaze or stain be provided.
  • These workpieces 2 are the coating chamber 1 via a roller conveyor 3 fed, of which only one roller is shown.
  • the roller conveyor 3 is assigned a engagable drive roller above the workpiece 2, however not shown in the drawing. Before the coating chamber 1 ends the Roller conveyor 3 and thus also the transport of the workpiece 2 through the roller conveyor 3 with the drive roller.
  • each chain 6, 7 has at least one lateral Angle bracket 8, 9, wherein the angle tabs 8, 9 arranged in alignment with each other are and record a cranked arm 10 in the illustrated embodiment.
  • This arm 10 projects with its free end 10 a in the area of Coating chamber 1 and carries there two spaced apart Cam 11.
  • the number, shape and arrangement of the cam 11 is largely free selectable and is adapted to the workpiece 2 or the desire of the operator.
  • the Wall 1 a of the coating chamber 1 now has a slot 1 b through which the Arm 10 can be moved.
  • the arm 10 may be at its free end, For example, in the area of the wall 1 a, still supported by slide rails become.
  • the arm 10 with the two cams 11 usually takes a position below the Roller conveyor 3 and thus below the roller. As soon as the end of a Workpiece 2 approaches the entrance of the coating chamber 1, this is from a sensor, for example a light barrier, detected via which the drive of the Chains 6, 7 is turned on. Now the arm 10 moves with the two cams 11 on the roller conveyor 3 and that at such a speed that the Cams 11 the workpiece 2 catch, at the rear end face to Concerns come and the workpiece 2 at a constant speed through the Transport coating chamber 1.
  • the distance between two consecutive Workpieces 2 can be relatively small, so that a results in relatively high throughput. This embodiment leaves it over In addition, too, that relatively high transport speeds of coating workpieces 2 are possible.
  • the cams 11 can with a nearly punctiform surface at the end of Workpiece 2 abut, so that no significant Impairment of the coating on the face occurs.
  • the cams 11 are adjustably attached to the end 10a of the arm 10 and can be replaced become. This makes it possible, the arrangement and design of the cam eleventh to adapt to transporting and coating workpieces 2.
  • the leadership of the chains 6, 7 may be designed differently. Basically it is possible to provide only one chain 6 or 7 for the arm 10. However, it must Ensure that the cam 11 always in a precisely predetermined position held to the workpiece 2. Depending on the length of the workpieces 2 and its transport speed, it is possible, two or more arms 10 with each to provide at least one cam 11. Furthermore, it is possible the chains 6, 7 with the arm 10 and the cam 11 to be arranged so that the cam 11 of moved up into the path of movement of the workpieces 2.
