[0002]

2. Description of the Related Art FIG. 21 is a plan view showing a conventional punch press device. The turret punch press 70 is provided with a fan-shaped turret 71, and the turret 71 is equipped with a plurality of molds. Then, the turret 71 rotates, and the work material (plate-shaped work) W is punched using a desired die. This work W is supplied to the turret punch press 70 through a conveyance path indicated by a chain line in the figure.

Therefore, the loading device 7 is provided before and after the work transfer route in the turret punch press 70, respectively.
3 and the carry-out device 74 are provided, and the work is stored in the storage shelf 75. As shown in the side view of FIG. 22, the storage shelves 75 are configured such that the pallets 77 are respectively stored in shelves provided in a plurality of upper and lower stages, and the works W are loaded on the pallets 77. The pallet 77 is taken out from the storage shelf 75 by a lifter 78 that can be raised and lowered on the side of the storage shelf 75, and is delivered to the carry-in device 73.

The carry-in device 73 has a carriage 73a which is movable between the position of the lifter 78 and the position of the carry-in device 73 passing through the lower part of the storage shelf 75, and is taken out from the storage shelf 75 by the lifter 78. The pallet 77 descends and is placed on the lifter 78, and then moves to the lower position of the loader 73b. The works W loaded on the pallet 77 are carried from the upper side to the moving mechanism 70a of the turret punch press 70 by the suction pads 73c one by one. The moving mechanism 70a holds the end portion of the work W and horizontally moves in accordance with the punch press operation.

The work W after processing is moved with one end being held by the holding arm 74a of the carry-out device 74, and at the same time, the surface receiving mechanism 74b is advanced in the same direction as the holding arm 74a, so that the lower surface of the work W is lowered.

Then, when the clamper 41 releases the holding of one end of the work W, the entire surface of the work W is transferred onto the lifter 24. When the work W after processing moves from the punch press machine 50 in the f2 direction, the work W to be processed next that has been waiting
Is positioned on the punch press machine 50 to start processing.

The work W on the lifter 23 is supplied to the turret punch press machine 50 one by one by the loader 30.
The work W after processing is stacked one by one on the pallet 7a on the lifter 24 by the unloader 40. At this time, the lifter 24 is height-controlled so that the work W position on the uppermost surface is always at the same position (immediately below the support mechanism 42).

This unloading operation is repeated for the designated number of processed workpieces W stacked on the pallet 7c. At this time, the lifters 23 and 24 alternately reciprocate in the e direction (the e1 direction and the opposite e2 direction) on the rail 21 every time the work W is supplied to and discharged from the turret punch press machine 50 one by one. Then, the work W is supplied from above the pallet 7c and carried out to the pallet 7a.
The unprocessed works W loaded on the pallet 7c are loaded on the pallet 7a by the designated number of processed sheets after processing.

Next, the pallet 7a on which all the processed works W are loaded is returned to the original storage position of the upper shelf 10. Therefore, as shown in FIG. 17, the lifter 24 performs a reverse operation to the lowering operation by the lifter 23. First, the lifter 24 moves upward in the g2 direction to lock the pallet 7a.
After being locked at 7 (the same state as in FIG. 10), the traveling carriage 15
It is transferred to the upper position (the same state as in FIG. 7) and returned from the traveling carriage 15 to the original storage position (on the conveyor 14a shown in FIG. 6).

The above operation is sequentially repeated for the pallets 7a to 7f loaded with the works W to be machined in units of the pallet 7. This operation is performed by loading the work W to be processed in advance on each pallet 7 on the upper shelf 10 and creating a program process in which the above-described operation is automatically processed at night, until morning. Has
All the processed works W can be stored in the pallets 7 of the upper shelf 10, and automation of the processing can be achieved. In addition, the work W loaded on each pallet 7
Can perform not only one press work by the above-mentioned one series of loading and unloading operations, but also by repeating this process a plurality of times, it is possible to deal with many kinds of small quantity.

Then, the pallet 7 on which the processed works W are loaded is taken out of the punch press device 1 in units of the pallet 7. At the time of taking out the pallet 7, the pallet 7 taken out by the traveling carriage 15 is
