Definitions

  • the workpieces to be coated are mostly hung on a overhead conveyor, usually undergo pretreatment and after drying applied with a spray system powder and that adhering to the workpiece Powder is then burned in. After cooling, the Workpieces suspended. Hanging up and hanging down is a labor-intensive process Operation that can rarely be automated, and that The hanger must be stripped from time to time.
  • a coating station in which the powder guns are installed in the powder booth is clearly described under patent EP 0 405 164 B1.
  • This has the disadvantage that the spraying elements, including their attachment, as well as powder supply hoses and cables, become occupied with powder over time despite air flow optimization, and occasionally powder falls on the workpiece to be coated, and the cabin can only be cleaned manually with great effort.
  • the spraying devices e.g. tribostatic or electrostatic guns or bells
  • the powder booth can be designed as a low, flat coating tunnel (10), which is not is only small and inexpensive but can also be easily cleaned manually or automatically.
  • the coating tunnel (10) is, so to speak, the smallest and simplest variant of a powder coating booth for flat workpieces (1).
  • this is done by the spray organs (2) at the beginning a coating tunnel (7) over the conveyor belt (3) at the Air intake (4) are installed and the powder cloud in Direction of transport along the conveyor belt (3) is sucked slowly on the workpiece (1) and partly on the conveyor belt (3) precipitates and the powder remaining in the air via the air extraction (5) at the end of the tunnel for powder recovery (cyclone / filter) is promoted according to known technology (Fig. 1).
  • the spray organs (2) are ideally slightly inclined to the conveyor belt (3) installed.
  • the spray organs (2) can be permanently installed or across Conveyor belt (3) can be constructed to oscillate.
  • a powder-repellent material such as plastic (single or sandwich construction) or glass or even from a ventilated Fluid material or textile fabric made.
  • the spray organs are installed in the ceiling of the coating tunnel (10), holes for the spray organs (2) being necessary in the ceiling of the coating tunnel and a fluid ring (12) in the vicinity of the spray head being able to protect against excessive powder accumulations .
  • the spray head and ceiling are designed to be as smooth as possible so that clean cleaning is possible (Fig. 2). With this arrangement, the suction can take place both at the entrance and exit of the coating tunnel (10) or only at the exit or entrance.
  • the coating tunnel (10) is provided with a cleaning device (11) which automatically cleans the inner surface of the coating tunnel (10) at intervals between sheets or when changing the strip, in that the cleaning device (11) travels along the tunnel to suction and back removed the tunnel entrance and any powder accumulations on the ceiling or on the side walls, e.g. B. by suction, blowing, scraping, wiping etc. (Fig 4.)
  • the coating tunnel (10) allows automatic cleaning, it is very suitable for quick Color change. With regular automatic cleaning and use of powder-repellent materials when building the coating tunnel (10) prevents powder from falling onto the workpiece (1) in an uncontrolled manner can.
  • the coating tunnel (10) therefore does not have to be used for the color change are driven out of the coating line, at most for maintenance and Repair purposes.
  • the conveyor belt (3) can also be used for this purpose. be moved laterally out of the coating section so that the coating tunnel (10) is open at the bottom. With this system the coating of flat workpieces on a flat transport system essential simplified.
