Definitions

  • the invention relates to a device for Spray coating objects with coating powder along an object transport route according to the Preamble of claim 1.
  • Round cabins have the advantage that they have no corners have, in which is undesirable Powder could accumulate to make it easier to are clean as a square cabin, and that by Object through-openings flowing into the cabin Air essentially bypassing the Cabin center along the inside wall of the cabin flows so that it covers the coating process of a in the cabin center ordered object.
  • the object of the invention is to be achieved when spray coating objects outside of one To avoid powder particles from the cabin Cabin can escape into the environment, being this advantage should be achieved without more air needs to be extracted from the cabin, than is required for the cabin alone and without additional air suction required are. These advantages should also then can be achieved when the objects to be coated have large areas or almost the width of the Corresponding object through openings of the cabin Have width or for coating object depressions or object cavities Spray device outside the cabin at an angle Object conveying direction must be directed. According to a further embodiment of the invention Device be designed such that it for a color change or at the end of one Coating process quickly and thoroughly can be cleaned.
  • the spray devices mentioned below 24,46,48 are of a known type and are therefore not described in detail. There are some which is a spray nozzle for spraying the powder while others have the powder through one Rotation head and centrifugal force generated by it spray. Preferably everyone works with electrical high voltage electrodes for electrostatic charging of the coating powder.
  • the device shown in Figs. 1, 2 and 3 for spray coating objects 2 with Coating powder 4 along an object transport path 6 contains 10 in a first cabin a first spray coating chamber 8, and in one second cabin 14 a second Spray coating chamber 12.
  • the first Spray coating chamber 8 has a horizontal section seen a round, preferably circular Cross-section.
  • 1, 2 and 3 is the second Spray coating chamber 12 along one of two of the transport route 6 at a distance from one another arranged, diametrically opposite each other Object through openings 16 and 18 of the first Spray coating chamber 8 functionally connected and directly adjacent to them there arranged.
  • the first spray coating chamber 8 are between the two object through openings 16 and 18 at least one, for example 2 x 2 each other oppositely arranged sprayer insertion openings 22 in the form of narrow vertical Slots for inserting automatic sprayers 24 in the first Spray coating chamber 8 formed.
  • the automatic spray devices 24 are controlled automatically and from a lift stand or robot 26 which it automatically relative to the Objects 2 can move.
  • the slit-shaped Sprayer insertion openings 22 can pass through overlapping sealing tapes between which the Spray devices 24 are inserted can.
  • a lifting stand or robot 26 can have several Wear sprayers 24.

  • the Filter means 29 filter excess powder (over-spray powder) of the coating powder 4 from the Suction air flow 32 so that it is recovered and can be used again.
  • the suction air source 30 is a well-known suction fan. The excess powder can in a known manner with fresh powder mixed and again the spray devices 24 are fed.
  • the two object through openings 16 and 18 of the first round cabin 10 can each through two door panels 34, which on the cabin wall 20 about vertical axes 36 are pivotally attached, optionally open or be closed.
  • door leaves can also other means, for example sliding doors be used.
  • the pivoting door leaf 34 are in the open state as Sidewall sections of the second Spray coating chamber 12 is used a funnel-like, diagonally diverging Have the open position and the side edges of the relevant object passage opening 16 of the Round cabin 10 with recessed to each other parallel side walls 40 of the second Bridge spray coating chamber 12. Thereby has the second spray coating chamber 12, starting from the neighboring object passage opening 16 of the round cabin 10, one gradually widening chamber width.
  • the second Spray coating chamber 12 has none Suction air outlet, but is opened by the adjacent object passage opening 16 of the first Spray coating chamber 8 through it Suction air outlet 28 of the first Spray coating chamber 8 so strongly sucked that air and powder from both chambers 8 and 12 is suctioned off and in all operating situations Coating powder neither from the first nor from the second spray coating chamber 8 or 12 in the outside environment can escape.
  • the second spray coating chamber 12 has on her from the first spray coating chamber 8 distal outer end of an object through hole 42. It also has at least a sprayer insertion opening 44 in at least one of the two side chamber walls 40.
  • the sprayer insertion openings 44 are relatively wide, so that hand-held Spray devices 46 or fixedly arranged Spray devices 48 through them from the outside into the second spray coating chamber 12 can be introduced to objects 2 with To coat powder 4 and at the same time Coating process by an operator observe. In this way, objects 2 either on one side or on the other Page, before or after the first Spray coating chamber 8 additionally coated become.
  • the side edges 52 of the outer object through opening 42 the second Spray coating chamber 12 are through each other opposite side margins of two in Door leaf 54 standing position formed, which on the side walls 40 of the second Spray coating booth 14 about vertical axes 56 optionally from the closed position to one Open position can be pivoted.
