Abstract
An automatic coating apparatus. A rotary atomizing head is washed with the fluid supplied from its front side by a washing nozzle. A coating machine is mounted on a coating robot for moving in arbitrary directions, while an atomizing head washer is located in the vicinity of the coating robot. At the time of a washing operation, the coating robot is actuated to put the rotary atomizing head into a waste liquid collecting container of the atomizing head washer. In this state, thinner is discharged from the washing nozzle toward the front side of the hub member of the rotary atomizing head. Thinner is then allowed to flow into the rotary atomizing head through solvent outlet holes in the hub member to wash off deposited paint from the rotary atomizing head.
