部取付のパイブレーク５を作動させて振動を加え、粉体
の浮遊流動状態を作る。In this method, as shown in Fig. 6, when powder coating small parts such as electronic parts, powder resin 2 is poured into a dipping tank 1, and a porous resin is poured from an air tank (reservoir) 3 at the bottom of the dipping tank. Air is jetted into the powder resin 2 through the elastic sheet material 4, and at the same time, an externally attached pie break 5 is activated to apply vibrations, thereby creating a floating and flowing state of the powder.

てはならない。A method for this purpose is to stop the instantaneous air flow and at the same time flatten the surface of the powder using a skid 6 with a knife. In order to achieve ideal powder adhesion by immersion under static conditions of the powder, δ must be immersed within 1 to 2 seconds after interrupting the air flow.

する。In the present invention, as shown in FIG. 1 and FIG.
A powder supply tank 7 having an air tank 3 similar to the immersion tank 1 is provided adjacent to the immersion tank 1, and the two are partitioned by an overflow wall 8 having a top surface a predetermined distance lower than the top surface of each type 1.7. When supplying powder from the powder supply tank 7 into the tank 1, reduce or eliminate the amount of air flowing into the immersion tank 1 via the air tank 3,
The amount of air flowing into the supply tank 7 via the air tank 3 is increased.
この結果、供給槽７内の粉体は第３図に示すように盛り

Next, if the amount of air in the immersion tank 1 is set to the size at the time of immersion or zero, the state shown in FIG. 5 will be obtained. This state indicates that the amount of powder in the dipping tank 1 was maintained constant. A constant supply of powder is thus achieved.
