Abstract

An electrostatic coating machine comprising at least two paint tanks (13A, 13B) for pushing out a paint by a pressure of a hydraulic fluid which one is attached to a rotary base (14) while being electrically insulated from each other, and can be positioned to a coating position opposed to the machine body (3) by the rotation of the rotary base (14) such that while one paint tank is at the coating position, the other paint tank is engaged with a paint charging attachment (22) that is disposed being electrically insulated from the machine body (3) and has a paint supply port (Ps) for supplying a cleaning fluid and a paint of a next color and a drain recovery port (Dr) for recovering drains. Cleaning/paint charging time can be shortened to improve operation efficiency and insulation countermeasure for the paint supply system can be saved.
