Abstract
Apparatus for the electrostatic powder paint spray coating of substrates, such as automotive vehicles, is provided. The apparatus includes modular applicators which are mountable into a programmable, robotically controlled housing. The modular applicators are switchable into and out of an operational mode on command, to facilitate different optimal coating procedures for coating differing surfaces, ranging from large, open surfaces to smaller, highly irregular substrate surfaces. The applicator heads may be spatially switchable on command from, for example, a bell cup spray applicator to a spray gun applicator. Flow control to each applicator is preferably enhanced using selectable pneumatically controlled pinch valves.
