Abstract
An apparatus for applying coating material to inner surfaces of cans includes a coating material spray gun and a cleaning material spray gun which are mounted in a side-by-side relationship on a manifold block. The coating material spray gun is connected in fluid communication with a coating material supply conduit through the manifold block. The cleaning material spray gun is connected in fluid communication with a cleaning material supply conduit through the manifold block. The cleaning material spray gun is operable to direct a flow of cleaning material toward a nozzle on the coating material spray gun to clean the nozzle. Three point mounting systems are utilized to accurately mount the spray guns on the manifold block. A heater is provided to maintain body of coating material in the coating material spray gun at a desired temperature. A transducer is provided to sense changes in the pressure of the coating material during operation of the coating material spray gun from a closed condition to an open condition. Cleaning material is conducted through the coating material spray gun to clean an interior portion of the coating material spray gun. The operating stroke of valve assemblies in the coating material spray gun and the cleaning spray gun are set by utilizing shims having thicknesses corresponding to the desired operating strokes of the valve assemblies.
