It will be. As the slide block 51 is moved to the left as shown in FIG. The member 55 is raised, and the scrap S held by the fixed jaw 53 and the movable jaw 57 is released.

As described above, the position where the cam follower 61 engages with one of the cam members 63 and releases its grip on the scrap S is a position corresponding to the enlarged part 25L of the slit part 25S of the tilting table 25 shown in FIG. Thus, it can be recessed into the upper surfaces of the tilting table 25 and the work table 9. Therefore,
As described above, when the slide block 51 is located at a position corresponding to one of the cam members 63, the vertical movement cylinder 45 is actuated to displace the vertical movement frame 39 downward. The fixed jaw 53 and movable jaw 57 can be retracted from the upper surfaces of the work table 9 and the tilt table 25.

As described above, by recessing the fixed jaw 53 and the movable jaw 57 from the upper surface of the fixed table 9, etc., the plate material W is transferred from the material supply device 3 to the plate material processing device 1.
This is extremely advantageous because the stationary jaw 53 and the like do not get in the way when feeding the plate material W and when moving and positioning the plate material W in the X-axis direction and the Y-axis direction with respect to the plate material processing device 1. .

Since the second cam surface 65S has a steep slope, the cam member 65 is swung leftward against the bullet 73 and gradually lowered. Therefore, the slide block 51 moves to the left beyond the lowered cam member 65 while holding the scrap S. That is, the scrap S is carried out in a direction away from the plate processing apparatus 1.

As is already clear, the slide block 51 carries out the scrap S to the left in FIG.
After releasing the grip on the scrap S near the left end, the tilting cylinder 35 is operated to tilt the tilting table 25 backward and downward, so that the scrap S is pushed into the scrap box 2 by its own weight.
It will be understood that the fall containment occurs in 3.

It is rotatably supported at the upper end of the. The vertical movement shaft 99 is always biased upward by an appropriately provided spring such as a coil spring (not shown), and its upper end is provided so as to be able to protrude and retract from the upper surface of the work table 9, etc. It is being One end of a suitable string-like member 101 such as a rope or belt is connected to the lower end of the vertically moving shaft 99, and the other end of this string-like member 101 is connected to the lower end of the vertically moving shaft 99. It is connected to the second link 81 at an appropriate position via a pulley 103 which is appropriately attached to the pedestal 29.

Therefore, as mentioned above, the guide bar 49
When the second link 81 is swung to reciprocate the slide block 51 along the
The vertical movement shaft 99 is moved up and down by the rocking, and the remaining material guide member 95 is moved in and out of the upper surface of the work table 9 and the like. The above-mentioned residual material guide member 95
When the slide block 51 is retracted in conjunction with the reciprocating movement of the slide block 51, the slide block 51 is moved into the cam 63.
This is at or before the time when the scrap S is located at the position corresponding to , and at or before the time when the scrap S is finished being carried out.

As understood from the above, the remaining material guide member 95
As a result, the scrap S is reliably guided onto the tilting table 25 and is reliably dropped. In addition, the remaining material guide member 95 and the slide block 5
1 are interlocked and recessed from the upper surface of the work table 9, etc., so that only one side does not protrude at any time, so neither of them becomes a hindrance.
