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 coating machine enables the inside of a paint chamber to be washed clean with less amount of use of thinner by increasing washing efficiency and is capable of forming a coating with uniform coating thickness by always uniformly jetting a paint over 360&#xb0; about a rotary atomizing head and the rotary atomizing head of the coating machine. The coating machine includes the rotary atomizing head in which the paint chamber is formed in the clearance between an outer bell fitted to the tip of a tubular rotating shaft and an inner bell fitted to the front side of the outer bell. Fins agitating, in the paint chamber, a washing fluid supplied from a thin tubular nozzle inserted into the tubular rotating shaft are radially formed on the rear surface side of the inner bell. An annular paint groove temporarily accumulating the paint is formed in the inner surface of the rim part of the outer bell on which the paint jetted from the paint jetting holes formed at the peripheral surface part of the paint chamber is extended.

Coating machine and rotary atomizing head thereof

A coating machine is capable of reducing VOC and COby atomizing a paint to increase depositing efficiency without lowering production efficiency and the rotary atomizing head of the coating machine. The coating machine includes the rotary atomizing head in which a paint chamber receiving the supply of paint is formed on the rear side thereof. A plurality of rims formed in a roughly truncated conical shape for extending the paint flowing out of the paint chamber by a centrifugal force and atomizing the paint at the tip thereof are fitted in the rotary atomizing head overlappingly at specific clearances. The clearances are opened to the peripheral surface part of the paint chamber. Accordingly, VOC and COcan be reduced by reducing the total jetted amount of paint to enable the atomization of the paint at low rotating speeds so as the increase the deposit efficiency.
