Abstract
An apparatus for manipulating a spray device having a spray nozzle relative to a target substrate, which apparatus includes drive mechanisms for moving the spray device in the X, Y and Z directions, and separate mechanisms for rotating the spray nozzle relative to the spray device and for tilting the spray nozzle relative to the spray device.
Claims26
Apparatus for applying a coating material to a surface, comprising:
- a spray device including an extension, said spray device being formed with an internal passageway having an inlet communicating with a source of coating material and an outlet formed in said extension, said internal passageway carrying a valve which is movable between an open position and a closed position with respect to said outlet formed in said extension;
- a spray nozzle having an inlet and a discharge outlet;
- mounting means for pivotally mounting said spray nozzle to said extension, said mounting means including:
- (i) an adaptor connected to said extension, said adaptor being formed with a bore;
- (ii) a nozzle support member rotatably carried within said bore of said adaptor, said nozzle support member having a bore within which said spray nozzle is fixedly mounted;
- (iii) said adaptor being formed with at least one passageway which interconnects said outlet of said extension with said bore of said nozzle support member for transmitting coating material from said extension into said spray nozzle;
- means for producing relative movement between said spray device and said surface along an X axis;
- means for producing relative movement between said spray device and said surface along a Y axis, said Y axis being perpendicular to said X axis;
- means for pivoting said spray nozzle with respect to said extension.

Apparatus for applying a coating material to a surface, comprising:
- a spray device including an extension, said spray device being formed with an internal passageway which passes through said extension and includes an inlet communicating with a source of coating material and an outlet formed in said extension, said internal passageway carrying a valve which is movable between an open position and a closed position with respect to said outlet formed in said extension;
- a spray nozzle having an inlet and a discharge outlet;
- mounting means for pivotally mounting said spray nozzle to said extension, said mounting means including:
- (i) a swivel base connected to said extension, said swivel base being formed with a cavity;
- (ii) a nozzle support member slidably mounted within said cavity of said swivel base;
- (iii) a nozzle holder mounted within a bore formed in said nozzle support member, said nozzle holder fixedly mounting said spray nozzle;
- (iv) means for sliding said nozzle support member and thus said nozzle holder and spray nozzle within said swivel base so that said spray nozzle is pivotal with respect to said extension;
- means for producing relative movement between said spray device and said surface along an X axis;
- means for producing relative movement between said spray device and said surface along a Y axis, said Y axis being perpendicular to said X axis;
- means for pivoting said spray nozzle with respect to said extension.
