It is installed on 5.

Reference numeral 18 denotes an endless timing belt disposed on the body 1 below the rail 7 in a horizontal direction and parallel to the moving direction of the moving table 6, and is rotated reciprocally by a servo motor 23 or the like.

One is a connecting body that connects the movable body 6 to the timing belt 18, through which the movable body 6 is caused to reciprocate by the timing belt 18.

Reference numeral 20 denotes a monitor television camera disposed above the support base 2, and its stand 21 is equipped with fine movement devices for left and right, up and down, and front and back movements.

The step motor 11 is controlled by a control device, and by rotation of the screw shaft 9, the movable body 12 attached thereto is moved by a required size.

22 is a plate glass. To operate this device, first, a glass plate for test cutting is placed on the supporting stands 2, 2, and the air cylinder 5 is operated to pressurize and fix the glass plate with the fixing body 4.

Next, by reciprocating the timing belt 18, the cutter 16 is reciprocated via the connecting body 19, the support frame 8, the movable body 12, the mounting body 13, etc., and the lower cutter 16 cuts the bottom surface of the plate glass. Insert the cutting line.

The cutting line is cut by operating the air cylinder 17 during either the forward or backward movement of the cutter 16.
6 is formed by pressing it against a plate glass.

Next, while viewing the image from the television camera on a monitor television, the upper mounting body 13 is moved to align the upper cutter 16 with the aforementioned cutting line.

With this, the pair of upper and lower cutters 16 overlap accurately on both sides of the plate glass, and the two cut lines formed overlap on the front and back sides of the glass.

In addition, when forming the cutting lines on the front and back sides of the glass plate at different positions, the upper cutter 16 is placed at a position a predetermined distance from the cutting line formed on the lower surface of the glass plate.

After determining the position of the cutter 16.16 in this manner, a reference line provided on the monitor television camera is aligned with the cutting line.

When the above operations are completed, the glass for test cutting is removed, and the cut glass is placed and fixed on the support stands 2, 2.

This type of plate glass, for example, liquid crystal glass, has a line indicating the cutting position, so by moving the base 3, the plate glass is moved together with the support 2, and the indication line is passed to the TV camera 2.
