Abstract

PURPOSE: To prevent mixing of powders and make possible color change coating within a short time by providing a mechanism of feeding two or more kinds of colored powders independently to a spray gun by way of plural pressure lead-in hoses, connectors, etc. and a mechanism of cleaning the residual powders of the connectors.
CONSTITUTION: Color change coating is accomplished by mutually interlocking solenoid valves SL1 thru SL7 through a control unit 18, selectively supplying pressure air to a connector 20 from a compressor 14, opening and closing the gate valves of connecting pipes 30, 40 according to this and supplying colored powders Ta and Tb to a spray gun 16. The device is so constituted that at the changing over of the colored powders Ta and Tb during this time, the solenoid valve SL3 is opened and closed intermittently for several ten seconds to feed the pressure air for cleaning into the connecting pipes 30, 40 thereby spouting the residual powders to the outside through the spray gun 16. According to this method, the need for manual changing of lead-in hoses in conventional methods may be eliminated and the device made compact.
