Next, the operation of the device of the present invention configured as described above will be described. As shown in FIG. 5 (a), when the work W sent out in the direction of arrow I by a predetermined length is cut by the cutter 2 of the primary cutting machine A, the work receiving device E in the raised position at this time is cut. The work W is adsorbed by the vacuum pad 32, and the work W is supported by the work support pins 33. By operating the air cylinder 26 in this state, the slide block 25 slides with respect to the guide bar 24 to receive the work. Device E is moved as indicated by arrow J. Then, the air cylinder 29 of the work receiving device E is operated to lower the frame 28 and the plate 31 as shown by the arrow K as shown in FIG. 5 (b). Then, when the work W is placed on the conveyor belt 18 of the work transfer device D, if the suction of the work W by the vacuum pad 32 is released, the work W is transferred by the belt 18 in the direction of the arrow L. The work transfer device D is driven by a motor 13. The work W sent to the secondary cutting machine B side by the belt 18 is transferred to the belt 22 on the way.

The stopper 34 of the work stopping device F at the position shown in (a)
Hits the front edge of the work W and stops the work W, and the air cylinder 45 of the work positioning device G operates to move the moving work guide 39 in parallel to sandwich the work W with the fixing work guide 37. By work W
Is positioned.

At this time, the work feeding device H is at the position shown in FIG. 5 (a), and the vacuum pad is activated by the operation of the air cylinder 51.
52 descends and adsorbs the work W. In this way, when the work W is attracted, the air cylinder 36 operates, the stopper 34 descends as shown in FIG. 5 (b), and the air cylinder 54 of the work feeding device H operates to cause the electromagnetic magnet. The work W adsorbed through the 55, the slide beam 49, the plate 50, the air cylinder 51 and the vacuum pad 52 is fed between the roller cutters 3 and 4 of the secondary cutting machine B. When the work W is caught between the roller cutters 3 and 4, the electromagnetic magnet 55 is demagnetized. However, since the feeding speed of the air cylinder 54 is slower than the cutting speed of the secondary cutting machine B, when the attracting force of the electromagnetic magnet 55 disappears, as shown in FIG.
49 separates from the electromagnetic magnet 55 and precedes. When the cutting of the work W progresses to some extent, the suction force of the vacuum pad 52 is released by the timer (not shown), so that the work W is further moved away from the pad 52 and the secondary cutting is completed. In the preceding slide beam 49, the pad 52 is stopped at the position where the workpiece W is separated, but the air cylinder 54
When the electromagnetic magnet 55 catches up with the slide beam 49 by the operation of, the electromagnetic magnet 55 is urged to attract the slide beam 49 again. If the air cylinder 54 returns in this state, the work feeding device H returns to the original position shown in FIG. 5 (a). When all the other devices are returned to their original positions, one cycle of the device of the present invention is completed.

(Advantages of the Invention) As described above, in the present invention, when the workpiece is continuously cut from the secondary cutting, the receiving, transferring, stopping, positioning, and feeding of the workpiece are all performed mechanically. Therefore, according to the present invention, it is possible to significantly improve the yield of products by eliminating the variation in processing accuracy and increasing the accuracy, and since the manpower conventionally required is not required, the work efficiency is increased and the labor saving of the work is achieved. It has an excellent effect that it can promote promotion of safety and safety.

In the present invention, the positioned work is fed into the roller cutter at a slower speed than the cutting speed of the roller cutter, because when the thin plate-like work is fed at a speed faster than the cutting speed, the work bends in the thin plate. Occurs, and the linearity of the cut surface deteriorates. That is, according to the present invention, it is possible to obtain the effect of improving the linearity of the cut surface.
