It is something.

[Conventional technology]

Conventionally, when processing workpieces such as bags, shoes, and clothing, belts were attached to rollers at both ends.

Processing devices such as sewing machines are placed along the conveyor belt, and workpieces are sequentially fed into the outbound path of the conveyor from the input port side, and each processing device takes in the workpieces on the conveyor and processes them sequentially. The finished product is then discharged from the end of the conveyor.

After the conveyor discharges the finished product, it makes a return trip and returns to the input port side for circulation.

By the way, in a conventional conveyance processing device, a workpiece is placed on an outgoing conveyor as a transfer device, the conveyor is stopped at a position where the workpiece corresponds to the processing device, and then the workpiece is placed on the conveyor. The upper workpiece is automatically fed to the processing equipment.

However, in the conventional conveyance processing apparatus configured as described above, even if the stop position of the conveyor is accurate, if a positional shift occurs such that the workpiece is not placed at the specified position on the conveyor. However, there is a problem that the positional relationship between the workpiece, the processing device, and the automatic feeding device is shifted, and the workpiece cannot be accurately and automatically fed.

Therefore, as a solution to the above problem, it may be possible to prevent the workpieces from shifting relative to the transport conveyor by providing workpiece storage sections at predetermined intervals on the transport conveyor.

However, this requires workpiece storage sections to be provided on both the forward path (top side of the transfer conveyor) and return path (bottom side of the transfer conveyor), which requires a large number of workpiece storage sections. There is a problem.

In addition, in this case, when conveying and processing multiple types of workpieces,
After processing is completed, the workpieces are manually sorted by type by the worker and stored in each storage section, which not only makes the storage work complicated and troublesome, but also causes the workpieces to be sorted incorrectly. It has certain problems.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a conveyance processing device that prevents displacement of the workpiece relative to the transfer device by simply providing a small number of workpiece accommodating portions, and that also allows finished products to be automatically taken out.
