Abstract

A spray coating application system for dispensing a liquid coating includes an elongated guide rail and a longitudinal slide plate slideably attached to the guide rail. The longitudinal slide plate is movable along a longitudinal axis of the guide rail between a first and second longitudinal positions. A transverse slide plate is attached to the longitudinal slide plate for concurrent movement therewith along the longitudinal axis of the guide rail. The transverse slide plate is moveable relative to the longitudinal slide plate in a transverse direction substantially perpendicular to the longitudinal axis of the guide rail. A spray nozzle is attached to the transverse slide plate for dispersing the liquid coating as a spray. A cam follower is attached to the transverse slide plate and engagable with a cam for moving the spray nozzle relative to the longitudinal slide plate between a first transverse position and a second transverse position.

First claim

What is claimed is:

1. A spray coating application system for dispensing a liquid coating, the system comprising:
a slide comprising a transverse slide plate movably attached to a longitudinal slide plate;
a spray nozzle for dispersing the liquid coating, the spray nozzle fixed for concurrent movement with the transverse slide plate;
a cam follower fixedly attached to the transverse slide plate for concurrent movement therewith, the cam follower including one of a roller or a slide; and
a cam engagable with the cam follower for moving the transverse slide plate relative to the longitudinal slide plate between a first transverse position and a second transverse position, the cam including a cam surface contoured to accommodate changes in a contour of a workpiece, the cam follower being configured to roll or slide along the cam surface, whereby a substantially consistent spacing between the spray nozzle and the workpiece is maintained.

2. The spray coating application system of claim 1 , wherein the slide is moveably attached to an elongated guide rail, the slide moveable along a longitudinal axis of the guide rail between a first longitudinal position and a second longitudinal position.

3. The spray coating application system of claim 2 , wherein the transverse slide plate is fixed for concurrent movement with the longitudinal slide plate along the longitudinal axis of the guide rail, the transverse slide plate moveable relative to the longitudinal slide plate in a transverse direction substantially perpendicular to the longitudinal axis of the guide rail.

4. The spray coating application system of claim 3 , wherein the longitudinal slide plate is moveable along the longitudinal axis of the guide rail and is fixedly attached to the guide rail in the transverse direction.

5. The spray coating application system of claim 1 further comprising a masking disk operable for blocking a portion of the liquid coating dispensed from the spray nozzle, the masking disk attached to the transverse slide plate for concurrent movement therewith, the spray nozzle located vertically between the transverse slide plate and the masking disk.

6. The spray coating application system of claim 5 further comprising a wiper slideably engaging the masking disk.

7. The spray coating application system of claim 6 further comprising a masking disk support bracket connecting the masking disk and the wiper to the transverse slide plate for concurrent movement therewith.

8. The spray coating application system of claim 7 , wherein the wiper is pivotally attached to the masking disk support bracket.

9. The spray coating application system of claim 5 , wherein the masking disk is rotatable about a masking disk axis of rotation.

10. The spray coating application system of claim 5 further comprising a spray coating collection tray removably mounted to the transverse slide plate for concurrent movement therewith, the spray nozzle located vertically between the spray coating collection tray and the masking disk.

11. The spray coating application system of claim 1 further comprising an elongated transverse slide rail connecting the transverse slide plate to the longitudinal slide plate.

12. The spray coating application system of claim 1 further comprising a biasing member connecting the transverse slide plate to the longitudinal slide plate, the biasing member operable for urging the transverse slide plate toward the first transverse position and away from the second transverse position.
