Thus, the clamp vise 18 moves the plate material W in the original direction of the material feeding direction by a predetermined distance, that is, as shown in FIG. 1, the distance from the position where the plate material aligning rollers 13 and 14 are installed to the saw 7 is installed. Move X and cut the primary.

FIG. 5 is a plan view when the plate materials W1 and W2 are secondarily cut, and FIG. 7 is a view taken in the direction of arrow Q in FIG. As described above, the cut plate material W is first inserted so as to be brought into contact with the elevating guide pins 9, 9 and 9 ', 9', respectively.
Then, when a start button (not shown) is pressed, the elevating guide pins 9 and the like are lowered and the clamp vise 18 is moved to chuck the respective plate materials W1 and W2 to fix the fixed guide pins 10 and 10 '. Move to. At the central position where the fixed guide pins 10 and 10 'are provided, the plate material aligning roller 13 attached to the air cylinder 11 as described above.
And the plate material aligning roller 14 attached to the air cylinder 12, in this case, the position where the plate material aligning rollers 13 and 14 do not move is the origin.

Next, when the centers of the plate materials W1 and W2 (positions divided into b and b in the figure) and the centers of the plate material aligning rollers 13 and 14 coincide with each other, these plate materials W1 and W2 are moved to chuck the clamp vise 18. To cancel. After the movement is completed, the gripping force of the air cylinders 11 and 12 is switched to high pressure, and then the mounting plate 15 (that is, the entire unit) is lowered. Then, the plate material aligning roller 13 fixes the end of the plate material W1 to the fixed guide pin 1.
The ends of the plate material W2 are pressed against the fixed guide pins 10 'and 10' by the plate material aligning roller 14 on the 0 and 10 sides, respectively. Next, when the air cylinders 11 and 12 are switched to a low pressure and each plate material W1 or the like has a warp or a back, the plate material aligning rollers 13 and 14 are retracted to eliminate the warp or the back, and then the plate vice W1 is again clamped by the clamp vise 18. Chuck W2. After chucking the plate material W1 or the like, the plate material aligning rollers 13 and 14 are moved to the original origin position, and the mounting plate 1 (entire unit) is raised to complete the plate material alignment. Thus, as in the case of the primary cutting, as shown in FIG. 15, the plate materials W1 and W held by the clamp vise 18 are used.
