Definitions

  • the present invention generally relates to the coating of workpieces with coating material, in particular coating powder.
  • the invention relates to the automatic coating of workpieces, particularly in a coating booth.
  • Coating booths for coating workpieces, in particular with coating powder are generally known from the prior art.
  • Such coating cabins generally have a coating chamber with a cabin floor, two workpiece passages opposite one another and a conveyor device for transporting workpieces to be coated through the coating chamber.
  • the conveyor device is usually arranged below the cabin floor of the coating cabin and has a workpiece carrier which projects through a conveyor slot in the cabin floor into the coating chamber of the coating cabin.
  • Coating booths with such "floor conveyors” are used in particular for the coating of high-quality workpieces, since a high coating quality can be achieved by arranging the conveyor device below the booth floor. This is due in particular to the fact that "classic" conveyors for suspended transport of workpieces through the coating chamber can encourage dirt particles or powder residues to fall from the conveyor device, which can lead to irregularities in the coating.
  • a large number of spray devices are usually used, which can be moved vertically up and down via a positioning device (in particular in the form of a lifting stand) which is usually arranged outside the coating booth.
  • the spray devices protrude from the positioning device through a vertical wall slot in the cabin into the cabin into a position opposite the workpiece to be coated.
  • the invention is based on the object of providing a solution with which a workpiece can preferably be coated from all sides automatically.
  • the invention relates in particular to an arrangement for preferably automatically coating objects with a coating material, in particular with coating powder, the arrangement having at least one spray device with a spray nozzle, via which the coating material can be dispensed in the direction of a main spray direction.

  • the spray device with the spray nozzle is designed such that the main spray direction of the spray nozzle deviates from the direction of extension of the guide by a predetermined or definable angle.
  • the spraying device of the arrangement according to the invention is designed in such a way that it does not spray the coating material horizontally or vertically, but rather obliquely from above or from below or vertically onto the object to be coated. Due to this inclination of the main spray direction, a significantly larger area, in particular angular or corner area, of workpieces can be achieved with the spray device.
  • Spray devices within the meaning of the present application can be spray heads or guns.
  • the spray nozzle can also be designed as a rotating body.
  • a spray device with a rotating body for atomizing coating powder is, for example, from the publication US 5,353,995 known.

  • the extension assigned to the at least one spray device is designed as a hollow body extending in the direction of extension of the guide, in which all supply lines necessary for the operation of the spray device are preferably accommodated or receivable. These are in particular supply lines for the coating material, electrical lines that may be provided for supplying the electrostatic charge and/or air lines for shaping air.
  • the main spray direction of the spray nozzles is 15° to 75°, preferably 25° to 65° and even more preferably about 40° to 50° deviates from the direction of extension of the guide, and preferably deviates in a vertical direction.
