- the loader 122 having the above configuration, it is possible to solve the above-mentioned problems. That is, due to the configuration of the loader 122 in which the inloader portion 124 and the outloader portion 126 are arranged side by side in the left-right direction, the molded product Wp can be unloaded from the sealing mold 202 by the outloader portion 126 while the work W is held by the inloader portion 124.
- the work W can be carried into the sealing mold 202 by the inloader part 124 by moving the inloader part 124 slightly (i.e., the distance between the centers of the inloader part 124 and the outloader part 126) to a position where the inloader part 124 matches the sealing mold 202 in the left-right direction. Therefore, compared to a conventional configuration, that is, a configuration in which one loader having one holding portion performs both loading of the workpiece and unloading of the molded product, the takt time in a series of processes can be significantly shortened, and productivity can be improved. In particular, as the number of press units 100B increases, a greater effect can be obtained.
- the device configuration can be made smaller and simpler, and the cost of the device can be reduced.
- the mold opening/closing time can be shortened, and the tact time can be shortened.
