Next, the object to be processed is intermittently transported in a straight line within the processing chamber by the processing section transport device, during which it is subjected to processing such as painting. The workpiece that has reached the end of the processing chamber is received by the exit side transfer device, and then loaded (returned) into the main transfer device.

Problems to be Solved by the Invention According to the above-mentioned conventional type, in the surrounding wall that forms the processing chamber, the processing section conveyance device is disposed, and the exit section is always open to the inlet section for passing the object to be processed. Therefore, when painting is performed, for example, a portion of the paint flows out through these openings, causing environmental degradation. A high-speed shuttle conveyor is used as the processing unit transport device, but
In this case, paint also adheres to the shuttle conveyor side, so maintenance such as removing adhered substances must be performed frequently to ensure smooth and accurate conveyance. Further, during electrodeposition, since the object to be treated moves through the liquid, the object to be treated is likely to be damaged by the resistance of the liquid.

The purpose of the present invention is to be able to easily perform processing operations such as electrodeposition and painting in a completely sealed chamber, and to be able to perform processing operations without moving the objects to be processed within the processing chamber, and to facilitate maintenance and management. The point is to provide processing equipment.
