Abstract
A spray coating system for spray coating articles as they move through a spray-coating region is disclosed. The system includes a conveyor for sequentially transporting a plurality of articles through the spray-coating region along a first path. A sprayer applies a spray coating to each article as it is transported through the spray-coating region. The sprayer is movable along a second path which runs parallel to the first path. A control circuit controls the movement of the sprayer along the second path as a function of the difference between the actual and desired instantaneous positions of the sprayer.

A spray coating system for spray coating articles as they move through a spray-coating region, said system comprising:
- (a) a conveyor for sequentially transporting a plurality of articles through said spray-coating region along a first path;
- (b) a sprayer for applying a spray coating to each said article as it is transported through said spray-coating region, said sprayer being movable along a second path which runs parallel to said first path;
- (c) position signal generating means for generating a first position signal indicative of the desired instantaneous position of said sprayer along said second path;
- (d) position signal generating means for generating a second position signal indicative of the actual instantaneous position of said sprayer along said second path;
- and
- (e) means for controlling the movement of said sprayer along said second path as a function of the difference between the actual and desired positions of said sprayer as indicated by said first and second position signals, respectively.
A method for spray coating articles as they move through a spray-coating region, comprising the steps of:
- (a) sequentially transporting a plurality of articles through said spray-coating region along a first path;
- (b) generating a first position signal indicative of the actual position of a sprayer along a second path, parallel to said first path, said sprayer spray coating each said article as said article is transported through said spray-coating region;
- (c) generating a second position signal indicative of the desired instantaneous position of said sprayer along said second path;
- and
- (d) controlling the movement of said sprayer along said second path as a function of the difference between said actual and desired positions of said sprayer as indicated by said second and first position signals, respectively.
