According to the present invention, even though the paint is filled or discharged repetitively to or from the paint bag (), so that bursting of a coating bag () or lack of coating material during coating are not caused by accumulation of error between the filling amount and the using amount. That is, before a predetermined amount of the coating material is supplied to the coating material bag (), the remaining coating material in the coating material bag () is extruded to empty it, since the coating material bag () is squashed by the pressure of fluid which was supplied to the hydraulic fluid chamber () outside of the bag.

Method and apparatus for filling coating material

A painting material charging device may comprise a cartridge attaching unit, a painting material supplying path, a first switching unit, a painting material supplying unit, a discharging path, a second switching unit, a painting material sensor and a controlling unit. The controlling unit may be configured to be connected to the painting material sensor and the second switching unit. The controlling unit may be configured to cause the second switching unit to fully close the discharging path in a case where the painting material sensor detects the painting material.

Painting material charging device

For providing a coating material cartridge capable of reliably discharging air and coating material stagnated in a hydraulic fluid chamber, a coating material cartridge has a cartridge main body, a partition body, a coating material transfer path and a plurality of hydraulic fluid transfer paths. The cartridge main body is detachably attached to a coating material filling device. The partition body partitions the inner region of the cartridge main body into a coating material chamber and a hydraulic fluid chamber. The coating material transfer path communicates the coating material chamber and the outer region of the cartridge main body, and each of the hydraulic fluid transfer paths communicates the hydraulic fluid chamber and a outer region of the cartridge main body. Each of the hydraulic fluid transfer paths has a plurality of openings that opens in the hydraulic fluid chamber and the distance for each of the openings from the connection end face is different from each other.

Coating material cartridge

A conveyor device for applying a high voltage to a work transported in a coating booth includes a conveyor device main body having a running base running in the coating booth and an electrode attachment attached to the running base being insulated therefrom for carrying the work and applying a high voltage to the work, an electromagnetic wave transmitter disposed in the coating booth for transmitting electromagnetic waves to the running base during running in a high voltage application zone and a low voltage generator means for receiving electromagnetic waves from the electromagnetic transmitter means and a high voltage generator for stepping-up a low voltage outputted from the low voltage generator and supplying a high voltage to the electrode attachment, mounted on the running base.

Conveyor device

An electrostatic coating apparatus for coating an electroconductive paint includes an electrostatic coating machine applied with a high voltage, a paint supply pipeline for supplying an electroconductive paint and a reciprocal pump disposed between the electrostatic coating machine and the paint supply pipeline and adapted such that the paint introduced from the input port is discharged at a predetermined flow rate from the output port of the pump and supplied at a predetermined amount to the electrostatic coating machine. The input port of the pump is made detachable from the paint supply pipeline. Electric insulation to paint supply pipelines can be saved. The reciprocal pump may be replaced with a paint charge pipe connected with a cleaning liquid supply pipe for supplying a cleaning liquid at a predetermined flow rate, thereby discharging the paint from the paint charge pipe.
