ROTARY ATOMIZING ELECTROSTATIC COATER, AND METHOD OF PREVENTING COATING CONTAMINATION OF THE SAME

PROBLEM TO BE SOLVED: To surely prevent coating contamination of a rotary atomizing electrostatic coater regardless of the condition of coating mist falling on a robot wrist 103a.SOLUTION: Timing (time lag T) at which voltages applied to a bell coating machine 102B and a robot wrist 103a by a voltage application means 10 are switched from relatively-high voltages (V/Vand V'/V') to relatively-low voltages (V'/V' and V/V), and timing (time lag T') at which the voltages are switched from the relatively-low voltages to the relatively-high voltages are respectively set. The voltage applied to the bell coating machine 102B is appropriately changed in response to a form of a coating object W, and an electrolytic barrier suitable for the charge conditions of coating mists Pd, Pi is formed in a peripheral region of the robot wrist 103a.
