Claims

[Scope of claim for utility model registration] Sheet supply section A, punching section B, strip section C
and an ejecting section D, the sheet gripping device 41 holds the sheet 32 fed from the sheet supplying section by its leading edge 55 and intermittently indexes the sheet to predetermined positions in the punching section, the stripping section and the discharging section. The punching section is configured to make cuts along the shape of the blank section so that the blank section 53 and the other cut-off sections are not completely separated, and the strip section is arranged to cut the blank section 53 from the other cut-off sections. 51
and a lower mold 101 to which the upper and lower molds 52 are attached, respectively, and these molds are relatively movable so that one approaches the other and moves away from the other, and the upper mold and the lower mold It has a shape that removes other cut-off parts from the blank part while maintaining the connection between the leading edge part and the blank part, and the unloading part includes a lower knock-off device 58 for pressing the leading edge part of the sheet from below. and an upper knock-off device 57 that presses the tip of the blank portion downward, the lower knock-off device includes a lower drive frame 122 and a lower knock-off die 135 attached to it, and the upper knock-off device includes an upper drive frame 121 and a lower knock-off mold 135 attached to it. In an automatic sheet material cutting machine comprising an attached upper knock-off die 125, a positioning device 85, 108 for the sheet transport direction and a direction perpendicular thereto is provided between the upper die and the upper form frame and between the lower die and the lower form frame. positioning device 86, 10 for
The upper knock-off mold and the lower knock-off mold are each integrally formed, and positioning devices 127 and 134 for the sheet transport direction are provided between the knock-off molds and the upper drive frame and the lower drive frame, respectively. An automatic punching machine characterized by being provided with positioning devices 123 and 124 for perpendicular directions.
