ELECTROSTATIC COATING GUN

摘要

A coating gun (2) includes: a high-voltage generating device (6) that is used to generate high voltage; an air motor (4) that is a motor portion to which the high voltage is applied; a bell cup (5) that is supported on a rotary shaft (4a) of the air motor (4) and to which the high voltage is applied; a CCV unit (7) that selectively supplies a plurality of types of coatings to the bell cup (5); a gun body (3) that is a casing and that contains the high-voltage generating device (6), the air motor (4) and the CCV unit (7); and a coupling portion (3c) that is used to couple the gun body (3) to a robot arm (8) and that is grounded. The air motor (4) and the CCV unit (7) are electrically connected to each other via a first resistor (11), and the coupling portion (3c) and the CCV unit (7) are electrically connected to each other via a second resistor (12).
