ていた。 However, for magnetic materials such as toroidal cores, for example, it is necessary to coat the entire surface with resin in order to provide insulation. When coating the entire surface of the workpiece with resin, the above method does not allow the resin powder to adhere to the supporting portion, resulting in uncoated areas. For this reason, in the past, the resin powder coating operation was repeated several times to avoid any remaining coating, but this resulted in extremely poor work efficiency.

特徴とする。"Structure of the invention" The powder coating apparatus according to the invention includes a fluidized resin powder bath, is rotatably supported along a plane substantially perpendicular to the upper part of the fluidized bath, and has a lower portion immersed in the fluidized bath. The workpiece carrier is provided with a plurality of workpiece storage chambers each having an open inner circumferential surface, and the workpiece storage chamber is arranged within the fluidization tank. A workpiece supplying means for supplying the workpieces one by one at a position where the workpiece is immersed in the liquid, and a workpiece retrieving means for receiving the falling workpiece at a position where the workpiece storage chamber rises from the inside of the fluidizing tank are provided.

ことができる。 Therefore, focusing on one workpiece storage chamber of the workpiece transporter, when the workpiece transporter rotates and the storage chamber is immersed in the fluidized tank, the resin powder floating in the fluidized tank is absorbed into the storage chamber. One workpiece deposited on the bottom and heated by the workpiece supply means is supplied into the storage chamber in that state. Since the workpiece rides on the resin powder deposited on the bottom of the storage chamber and comes into contact with the floating resin powder, the resin powder is welded to the entire surface. Then, when the workpiece carrier rotates further and rises from within the fluidized tank, the opening surface of the storage chamber faces downward, and the workpiece falls. The fallen workpiece is received by the workpiece take-out means and transported to a predetermined location. In this way, resin powder can be applied to the entire surface of the workpiece in one operation.

容室２１が形成されている。 The workpiece carrier 20 has an annular shape as a whole,
It is supported on the pair of rollers 18 with two portions of the lower peripheral wall sandwiched between the flanges 18a. Therefore, the workpiece conveyor 20 is configured to rotate along a substantially vertical plane due to the rotation of at least one of the rollers 18. The workpiece carrier 20 is formed with a plurality of workpiece storage chambers 21 each having an open inner peripheral surface.

着される。 In the above configuration, if we pay attention to one workpiece storage chamber 21 of the workpiece transport body 20, the workpiece transporter 20 rotates and the storage chamber 21 is moved to the fluidization tank 10.
When the resin powder P is immersed in the flow chamber 14 , the resin powder P floating in the flow chamber 14 is deposited on the bottom of the storage chamber 21 . When the storage chamber 21 reaches point A in FIG. 2, one heated workpiece W is supplied into the storage chamber 21 from the supply chute 30 in that state. The workpiece W rides on the resin powder P deposited at the bottom of the storage chamber 21 so that its lower surface contacts the resin powder P, and its upper surface and side surfaces contact the resin powder P floating in the flow chamber 14. Therefore, the resin powder P is welded to the entire surface.

is received by the removal chute 40 and transported to a predetermined location. In this way, the resin powder P can be attached to the entire surface of the workpiece W in one operation. Furthermore, one rotation of the workpiece carrier 20 allows one workpiece W to be processed in each storage chamber 21, resulting in good workability. The work W to which the resin powder P is attached in this manner is placed in a heating furnace and heated to completely harden the resin. Note that if it is desired to form a thick resin film, the above operation may be repeated two or three times.

性よくワーク全面を塗装することができる。"Effect of the invention" As explained above, according to the invention, the workpiece is supplied to the storage chamber of the workpiece carrier located in the fluidized tank, so that the resin powder accumulated at the bottom of the storage chamber is removed. By riding on the resin powder and coming into contact with the floating resin powder, the resin powder can be attached to the entire surface. Furthermore, the workpiece can be dropped and taken out from the storage chamber at the portion where the workpiece carrier rises from the fluidized tank. Therefore, the entire surface of the workpiece can be coated with good workability.
