Abstract
A coating method by the use of a rotary atomizing head type coating system (21), permitting to make multiple color changes in the course of a coating operation by providing a plural number of paint cartridges (35) of different colors which can be replaceably and removably loaded on the coating system. The coating method for the coating system includes: a paint cartridge loading step of setting a paint cartridge (35) of a specified color in a housing (22); a coating step of supplying paint in the loaded paint cartridge to a rotary atomizing head (30); a paint cartridge unloading step of unloading the paint cartridge (35) from the housing (22) after finishing a predetermined coating operation; and a washing step of feeding a washing fluid from an atomizing head washing device (57) to the front side of the rotary atomizing head (30) to wash away deposited residues of a previous color therefrom. Accordingly, when changing the color of paint, a coating operation in a new color can be started simply after washing the rotary atomizing head (30) from front side and replacing the paint cartridge by a new one.
