PROBLEM TO BE SOLVED: To provide a powder supply apparatus for uniformly spraying powder paint from a spray gun, particularly for supplying a small quantity of powders in a uniform fluidized state from an initial stage of the spraying in a field of powder coating for spraying the powder paint with the spray gun to deposit on a material to be coated to form a coating film. SOLUTION: In this apparatus capable of stably supplying even in a small quantity of powders, a hopper type powder vessel is supported by a repulsing member (spring), a vibrator whose one part is constituted of an elastic body is provided inside the vessel, and the powder in the vessel is fluidized by separately vibrating the vessel and the vibrator with one vibration producing means (vibrator) to be sent out from a supply port. The vibration producing means vibrates the vessel directly and also a movable member on the tip part of a vibration body fixed to the vessel or a vessel cap with the elastic body to fluidize the powder by inside and outside vibration which are different from each other. The supply of the powder is controlled by the operation of a powder spray gun using the vibration producing means by air and an ejector pump. COPYRIGHT: (C)2005,JPO&NCIPI |
