A coating machine having a coating material discharging mechanism for discharging
a previously filled coating material under pressure to an atomizing mechanism wherein a coating material bag for filling a coating material is housed in a coating material discharging chamber of a predetermined volume and an inlet/exit port of an operating fluid is disposed for exerting a pressure from the outside of the coating material bag thereby discharging the coating material under pressure, while crushing the coating material gag, whereby paint or like other coating material can be discharged under pressure reliably by a small driving force.
A coating machine having a coating material discharging mechanism for discharging a previously filled coating material under pressure to an atomizing mechanism wherein a coating material bag for filling a coating material is housed in a coating material discharging chamber of a predetermined volume, and an inlet/exit port of an operating fluid is disposed for exerting a pressure from the outside of the coating material bag thereby discharging the coating material under pressure.
A coating machine according to claim 1, wherein a plural coating material bags are provided to the coating material discharge chamber, and switching valves are interposed in coating material discharge flow channels from each of the coating material bags to the atomizing mechanism for selectively supplying the coating material from one of the coating material bags to the atomizing mechanism during entering of the operating fluid.
The present invention concerns a coating machine provided with a coating material discharging chamber for previously filling a coating material and discharging the same under pressure to an atomizing mechanism during coating and, more specifically, it relates to an electrostatic coating machine for electrostatically atomizing a conductive coating material such as an aqueous paint.
