Claims
- 1. Apparatus for applying coating material onto objects, comprising:
- a spray booth having an interior which provides a controlled area for the application of coating material onto objects moving therethrough;
- means for creating a flow of air through said interior of said spray booth within which oversprayed coating material is entrained for collection;
- a dispenser housing having an outer surface formed within a leading edge, a trailing edge and side walls extending between said leading and trailing edges;
- means for mounting said dispenser housing within said interior of said spray booth so that said leading edge is first to contact the flow of air therethrough, said outer surface of said housing promoting substantially laminar air flow adjacent to and below said housing; and
- means for mounting at least one coating dispenser to said trailing edge of said dispenser housing in a position to apply coating material onto objects moving through said interior of said spray booth.
- 2. The apparatus of claim 1 in which said side walls of said housing are each formed in a generally convexly curved shape along at least a portion of the length thereof.
- 3. The apparatus of claim 1 in which said housing comprises:
- a plurality of longitudinally spaced ribs;
- first and second longitudinally extending spars which are spaced from one another;
- means for interconnecting said first and second spars and for supporting said ribs;
- an outer skin connected to said ribs.
- 4. The apparatus of claim 3 in which said at least one coating dispenser comprises:
- a dispenser body mounted to one of said first and second spars, said dispenser body being formed with a coating delivery passageway for transmitting coating material;
- a nozzle mounted to said dispenser body in communication with said coating delivery passageway;
- means carried by said dispenser body for electrostatically charging coating material discharged from said nozzle.
- 5. The apparatus of claim 4 wherein said means for electrostatically charging the coating material comprises:
- an electrode assembly carried by the dispenser body in a position proximate a discharge outlet of the nozzle; and
- a dielectric block carried within a bore of the dispenser body and electrically connected to the electrode assembly at one end and an electrostatic cable at the other.
- 6. The apparatus of claim 5 wherein said electrostatic cable is disposed within a dielectric tube extending from the bore to a mounting block; wherein the dialectric block comprises a plurality of resistors potted together; and a means for forcing the electrostatic cable into electrical contact with one of the resistors.
- 7. Apparatus for applying powder coating material onto objects, comprising:
- a spray booth having an interior which provides a controlled area for the application of coating material onto horizontally oriented surfaces of objects moving therethrough;
- means for creating a flow of air through said interior of said spray booth within which oversprayed coating material is entrained for collection;
- a dispenser housing having an outer surface formed with a leading edge, a trailing edge and side walls extending between said leading and trailing edges;
- means for mounting said dispenser housing within said interior of said spray booth in a position above the horizontally oriented surfaces of objects moving through said spray booth and so that said leading edge is first to contact the flow of air therethrough, said outer surface of said housing promoting substantially laminar air flow adjacent to and below said housing; and
- means for mounting at least one coating dispenser to said trailing edge of said dispenser housing in a position to apply powder coating material downwardly onto the horizontally oriented surface of objects moving through said interior of said spray booth.
