Next, the slide table 2 descends again,
The suction element 14 that has received the unprocessed work 101 reciprocates with the perforation unit 3 to perform perforation processing, and moves up the slide table 2 again. The lowering of the slide table 2 is continued until the machined work 102 pierced by the piercing unit 3 moves again to a position just above the machined work mounting portion 22 of the slide table 2. As described above, since the slide table 2 descends before the suction element 14 moves to the perforation unit 3 to perform perforation, the unprocessed work 101 rubs against the upper surface of the slide table 2 even in an approaching relationship. It is possible to avoid such a risk (FIG. 4A). Then, when the slide table 2 is operated to pierce the unprocessed work 101 by the piercing unit 3,
The processed work mounting part 22 located at the unloading site b is returned to the position for receiving the processed work 102, and the work mounting part 12 is returned to the position immediately before the work feeding means 1 and the work mounting part 12 is moved to the work mounting part 12. Then, the unworked work 101, which has been cut by the required length by the work feeding means 1, is held by suction (FIG. 4B).

It is delivered when the suction of the element 14 is released (FIG. 4C). Then, the above steps are sequentially repeated to carry in the unprocessed work 101 and the processed work.
And unloading 102 at the same time.

Since the above process is an initial process, the processed work 102 is not actually held by suction on the processed work mounting portion 22 which has reached the unloading site b. In the subsequent repetition process, the processed work 102 is suction-held on the processed work mounting portion 22, and when the processed work 102 reaches the unloading site b, that is, immediately below the unloader suction means 6, the slide table is moved. 2 rises by a predetermined amount, and air is blown out from the air suction blowout holes 52 to float the processed work 102 and, at the same time, is sucked by the suction means 6 to suck and hold the processed work 102 by the suction means 6. Will be handed over. Upon returning, the unworked work 101, which has been cut by the required length by the work feeding means 1, is sucked and held on the work mounting portion 12 in the same manner as described above.
Is raised by a predetermined amount, and the suction of the suction element 14 is released, and the processed work 102 is suctioned to the processed work mounting portion 22.
The suction holding by the suction means 6 is released when the slide table 2 returns again as described above, and
102 is dropped on the stack magazine 5 immediately below. Cutting, carrying in, perforating, and carrying out of the raw material of the soft work wound in a roll shape in this manner are performed by repeating a series of operations (FIGS. 5A, 5B, and 6C). (B) (b)
(C)).

FIG. 7 shows a case where the suction means 6 for the processed work is not fixedly provided but can be moved up and down. In the case of this embodiment, as described above, the slide table 2 is moved down to the inside of the stack magic gun 5 within the time from the backward movement to the re-forward movement, and the suction is released to cancel the processed work.
102 are stacked in multiple stages, and the suction means 6 is raised again.

Although not shown, the present invention also includes carrying-in of the unprocessed work 101 and carry-out of the processed work 102 on a small slide table 2 having only one work mounting portion 12. . In this case, the slide table 2 is moved to the intermediate position of the reciprocating area a where the unworked work 101 fed and cut by the work feeding means 1 can be transferred to the suction element 14 of the moving means 4 and stopped. Then, the processed workpiece 102 is received on the spot, and is moved to the unloading site b, and the suction means 6 fixedly disposed for the unloader and the suction means 6 which can move up and down as described above.
The control should be passed to the user. The slide table 2 is configured to be movable up and down so as to approach the suction element 14 when transferring the work to the suction element 6 for the unloader when the work is transferred to and from the suction element 14 of the moving means 4. The holes 52 are switched to air-push when transferring the work to the suction element 14 of the moving means 4 and when the processed work 101 is located at the unloading site b, similarly to the above embodiment.

[0028]

Processed work) Since the transfer of the processed work and the unloading of the processed work to the unloader are performed, a series of cuts, cuts, cuts, cuts, cuts, cuts, cuts to the required length (area), and rolls out the work from the raw material of the rolled work. It is possible to provide a punching device for automatically and speedily performing the above operation. Needless to say, there is no need for any work before cutting the work wound into a roll into a predetermined length and setting it in the work holder. Moreover, the slide table moves up so as to approach the suction element only when the work is exchanged with the suction element of the moving means. When moving up, it is in a down state. Therefore, when the suction element moves to the punching unit or when the suction element moves to transfer the processed work directly above the slide table, the work that is slightly bent actually rubs against the upper surface of the slide table to deteriorate the quality. It is possible to take safety measures without fear. (Claim 2) Since the slide-table is air-pushed to adsorb to the suction element of the processed work and the processed work is naturally dropped to the stack magazine by releasing the suction, the pick-up is carried out when the processed work is carried out. It does not require a movable unloader such as an AND place, and can be provided at low cost. (Claim 3) If the suction means disposed above the unloading portion of the processed work is movable up and down, it is naturally dropped from the bottom of the stack magazine or a position approaching the stacked processed work. Stackable and work-friendly design. (Claim 4) Moreover, a series of operations of cutting, punching, and unloading a required length (area) while unwinding the work from the raw material of the work wound in a roll shape, and loading and unloading the processed work.
