The present invention relates to a suitable processing device.

(Prior art) This type of conventional processing equipment generally consists of a combination of a press machine and a large number of die sets (molds), and processes are performed sequentially while changing die sets as appropriate depending on the processing mode. . Recently, with the diversification of consumer values and the shortening of delivery times, it has become impossible to perform the same processing in large quantities as in the past, and die sets must be replaced more frequently. It has become. It often happens that two or three molds are processed and the molds need to be replaced.

Die sets can weigh as much as 30 kg depending on the item, and the effort required to replace the die set is extremely large, which not only imposes a severe burden on the worker, but also increases the possibility of injury during replacement work, and further reduces productivity. Various problems have arisen, such as a decline in

Several devices have been proposed in the past to solve these problems. For example, the device disclosed in Japanese Patent Application Laid-Open No. 5886941 is equipped with a shelf supporting a large number of die sets on the back of a single press machine, and a desired die set is selected from the shelf and transferred to the press machine using mechanical force. I'm trying to set it up.

Therefore, this device does not require human power to replace the die set, which reduces the burden on the operator and reduces the risk of injury.

(Problem to be solved by the invention) However, the device is large and complicated, making it expensive, and since the entire shelf on which many die sets are mounted moves, the movement is slow, and the press machine After removing the die set set in and returning it to the specified shelf position,
Since it is necessary to select a new die set and set it in the press machine, there are many problems that still need to be solved, such as the time it takes to replace the die set.

Therefore, an object of the present invention is to reduce the burden on the operator, and to make it possible to change the processing of the mold material in a short time with simple operations.
Another object of the present invention is to provide a processing device suitable for high-mix, low-volume production that can reduce costs.
