It is related to.

``Prior Art'' Conventionally, in order to transport electrical parts and the like as objects to be transported, the belt is moved by placing the objects on a belt that is movably attached between pulleys and driving and rotating the pulleys. The conveyed goods are conveyed to the target location by means of a belt. In this case, it may be necessary to perform various treatments such as washing, deburring, or spraying marks on the transported goods during the transport process.

Conventionally, when performing such processing, a conveyor belt transports the conveyed item to the position of the processing device where a predetermined process is performed, the processing device is sent in, the processing device performs the predetermined processing, and then the product is transported again. They were then transferred to a regular belt and transported to a designated location.

Therefore, in order to perform various processing on the transported products, the transport belt is extended to each processing device position to form a transport path with a long transport distance, and the transported products are In order to carry out the processing in the processing device, it is necessary to supply the material to a processing device separately provided outside the conveyance path, making the overall structure larger and more complicated.
