Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention involves reciprocating the jig with a workpiece set in the jig between a setup device and a processing device, and then moving the jig back and forth between a setup device and a processing device. This relates to processing equipment that performs a desired processing on a workpiece set in a tool.

BACKGROUND TECHNOLOGY Conventionally, as shown in Japanese Patent Application Laid-Open No. 172451 of 1986, this type of processing equipment has been equipped with a conveyor cart that can freely travel back and forth on a fixed path, and a setup is placed on one side of the fixed path. A configuration is provided in which a plurality of devices and a plurality of processing devices are provided, and a shelf for a pool is provided on the other side. According to this conventional method, a setup device removes the workpiece from a jig and attaches the workpiece, and then the jig with the workpiece set on the setup device is sent to the processing device using a conveyor cart, or I send it to the shelf and pool it. Furthermore, after processing, the jig is taken out from the processing device to the setup device using a conveyor truck.
In addition, the jigs pooled on the shelf are delivered to the processing equipment by a conveyor truck during unattended operation at night, and returned to the shelf after processing.

Problems to be Solved by the Invention In the conventional format as described above, there is only one shelf, so the amount that can be pooled is not large. Therefore, it is possible to increase the amount of pool by setting up multiple shelves, but since high accuracy is required for transferring jigs to processing equipment and setup equipment, the transport vehicle must have a high-precision lifting function that can handle multiple shelves. It is impossible to have it accurately. Furthermore, since the setup time is determined by the capacity of the transport vehicle, efficient work cannot be expected. Furthermore, it is sufficient for the setup using the setup device to be carried out intermittently for a short period of time, and having a worker constantly assigned to such work increases costs.

An object of the present invention is to provide processing equipment that can process a large number of pools and can perform setup work efficiently.
