<P>PROBLEM TO BE SOLVED: To provide an electrostatic coating device which can certainly prevent the device itself from being stained by a coating material, in such a state that a direct coating material mist and an indirect coating material mist exist as mixed around a robot arm, as well as a method for preventing an electrostatic coating device from being stained by a coating material. <P>SOLUTION: A controller 9b functions as follows: That is, the case is such that a plurality of different kinds of coating material mists (e.g. two different kinds of coating material mists) with varying characteristics, are present in mixed fashion around the robot arm 4. Voltage generated by a high voltage generation part 9a is converted by the controller 9b to a plurality of pulsatile electric potentials complying with the respective characteristics of each coating material mist, at predetermined periods which can meet the property of a coating material mist (i.e. a coating material mist including each different kind of coating material mist) which exists around the robot arm 4. <P>COPYRIGHT: (C)2011,JPO&INPIT |
