An electrostatic coating method in which a plurality of coating materials is respectively retained in a plurality of coating-material containers in a coating material cartridge, and the coating materials are changed by a valve at the time of sending of each of the coating materials, in an electrostatic coating device, each of the coating materials is sent from the coating material cartridge to a coating machine via a common path according to the change, and multilayer coating is performed by the electrostatic coating device.

Electrostatic coating device and electrostatic coating method

An electrostatic coating device and an electrostatic coating method each achieve a reduction in working hours and efficient coating at the time when layers are coated with colors. The electrostatic coating device includes a coating material cartridge that includes coating-material containers, a valve that makes a change of colors of coating materials, a common path through which coating materials are able to pass according to the change, and a cleaning circuit that cleans up the common path. The coating material cartridge is configured to be removable from a coating machine. The coating material cartridge may include individual paths respectively connected to the coating-material containers and each of which one of the coating materials passes through, and valves each connected to the common path and respectively connected to the individual paths. Each of the valves may open and close a conduit line between the common path and a corresponding coating-material container.
