No. 415 discloses this.

When a cutting line in the X-axis direction is cut into a large sheet glass placed on a table, the sheet glass cutting apparatus first moves the second traveling body toward a predetermined position of the first traveling body, and then moves the second traveling body toward the predetermined position. After lowering one cutter, the first traveling body is caused to travel in the X-axis direction.

[0004] When a cutting line in the Y-axis direction of a sheet glass is to be inserted, the first traveling body is first traveled, the second traveling body is traveled to a predetermined position, and the second cutter is lowered. The traveling body is caused to travel in the Y-axis direction.

However, the parallel distance (parallel spacing) of the cutting lines cannot be made smaller than the dimension between the both side surfaces of the slider (even if the side surfaces of the slider abut each other).

[0008] For this reason, there is a problem that the cost is remarkably increased because a cutter corresponding to the pitch of the parallel cutting line is separately manufactured.

It is also conceivable to provide one slider on the guide rail and move this slider before machining the next cutting line so as to match the pitch of the parallel cutting lines.

[0010] In this case, it takes much time and inefficiency, resulting in a significant increase in cost and an error in the dimension between the cutting lines.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a sheet glass cutting apparatus capable of forming a cutting line having a parallel interval equal to or less than the dimension between both sides of the slider by using the cutters of the sliders arranged in parallel.

As described above, according to the sheet glass cutting apparatus of the present invention, a cutting line is cut by the parallel first cutter, and then the parallel cutting machine is fed by a constant pitch transversely between the parallel cutting lines. Since the cutting line can be cut with one cutter, cutting lines with any small parallel pitch can be cut, and work efficiency for cutting lines can be significantly improved.

In addition to cutting lines intersecting by turning the table, parallel cutting lines having a small pitch can be efficiently inserted by moving the table and using the parallel first cutter.

Further, the first and second cutters of the first and second traveling bodies are arranged side by side at a constant pitch by the transverse feeder of the first and second cutters, and the first and second cutters intersect vertically and horizontally. You can cut it.

Further, it is also possible to insert cutting lines of a plurality of first cutters of the first traveling body and a traveling body with a second cutter of the first traveling body both vertically and horizontally and at a small pitch.

A traveling seat for reciprocating traveling in the X-axis direction;
With a traveling table that reciprocates in the Y-axis direction on the traveling seat, a cutting line with a large pitch and a cutting line with a small split can also be inserted through the parallel first cutter.

Further, a large cutting line and a small cutting line can be formed by a table reciprocating in the X-axis direction and a parallel first cutter having a traversing device.

Further, the position of the cutter can be adjusted by rotating the nut, and the movement position can be easily confirmed with the scale and the pointer.
