As described above, the turret punch press 1
Since the work loading / unloading device 3 is provided on one side, the overall operation is as follows. First, referring to FIGS. 1 to 4, first, the work is loaded into the shelf 103 provided in the shelf unit 35. The empty pallet P that has been moved is transferred to the traverser device 113.
Is pulled out into the lifter frame 125 and the lifter frame 125 is moved to the lowest stage. Then, by the operation of the traverser device 113, the empty pallet P is temporarily provided in the plate material single-sheet taking unit 31 and the loading lifter device 41.
It is transferred onto the mounting table 57 which is one member.

After the transfer, the carry-in lifter device 41 is moved into the adjacent integrated unit 33, and the carry-in lifter device 41 is moved.
The empty pallet P is lowered onto the mounting table 87 provided in the carry-out lifter device 75 provided in the stacking unit 33 by lowering the mounting table 57 provided in. Then, the mounting table 57 provided on the carry-in lifter device 41 is raised and returned to the original position.

Next, the pallet P to be used among the pallets P on which the works W stored in the shelf unit 35 are placed.
In the same manner as the movements of the traverser device 113 and the lifter frame 125 described above.
Mounting table 5 which is a member of the carry-in lifter device 41 provided in the
7 is transferred and the preparation for processing is completed.

From this state, the single plate material taking unit 31
Suction means 43 depending on a loading device 45 provided in the
Then, the vacuum suction pad 63, which is No. 3, is lowered, and the side portion of the uppermost work W loaded on the pallet P is suctioned and lifted. Then, the roller conveyor device 49 is driven to cause the roller 47 to enter between the lifted first work W and the remaining second work W, and the roller 47 supports the first work W. . From this state, the loading device 4
