Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plate-like body positioning method and apparatus for positioning a plate glass at a cutting line processing position on a cutting table of a glass cutting machine.

[0002]

2. Description of the Related Art From a base plate of a plate glass 1 shown in FIG.
When cutting out 3, 4 and 5, two sides 1A and 1B of the plate glass 1
If not accurately positioned or confirmed, the products 2 ₁ , 2 ₂ , cut out along the two sides 1A, 1B,
It is not possible to cut out 2 ₃ , product 3 ₂ and products 4 ₁ and 4 ₂ with accurate dimensions. Therefore, in order to accurately cut out the products 2, 3, 4, 5 from the base plate of the plate glass 1, it is necessary to accurately position or confirm the two sides 1A, 1B of the plate glass 1.

Therefore, when the plate glass is cut by a glass cutting machine, the plate glass is positioned at a predetermined position by a plate glass positioning device provided on the cutting table, and then the plate glass is cut into a desired shape by a cutter of the glass cutting machine. In the conventional glass cutting machine, the positioning device projects from the cutting table that serves as the sheet glass conveying path. Therefore, when the sheet glass is slid, the protrusions become obstacles and the sheet glass cannot slide from the sheet conveying path to the cutting table. Therefore, the plate glass is adsorbed in front of the positioning device by using an adsorbing device or the like, and the adsorbed plate glass is lifted and placed on the cutting table from above the cutting table.

As described above, in the conventional positioning device, the plate glass cannot be automatically slid from the conveying path to the cutting table, so that there is a problem that productivity cannot be improved. In order to solve this problem, the applicant of the present application has proposed a positioning device shown in FIG. 7 in Japanese Patent Laid-Open No. 3-32540. According to this positioning device, when the front surface 10A of the plate glass 10 conveyed in the direction of the arrow A from the conveyance path comes into contact with the first pressing member 12, the first pressing member 12 rotates about the pin 14. And is pushed downward from the front side of the cutting table 16. The pressed first pressing member 12 automatically projects onto the surface of the cutting table 16 after the plate glass 10 has passed therethrough.

Then, the first pressing member 12 protruding above the surface is moved in the direction of the arrow A, and the front surface 10B of the plate glass 10 is moved.
Press. As a result, the front surface 10A of the plate glass 10 is pressed against the first positioning member 18. In addition, the front surface 10A of the plate glass 10 is pressed against the first positioning member by the first pressing member 12, and the second pressing members 20, 20 are pressed.
Is moved in the direction of arrow B, and the side surface 10C of the plate glass 10 is pressed. As a result, the side surface 10D of the plate glass 10 is pressed by the second positioning members 22, 22, and the plate glass 10 is positioned at the cutting position. As a result, the plate glass 10 slides on the conveying path and automatically moves to the cutting table 16, so that the productivity is improved.

[0006]

However, in the case of the positioning device shown in FIG. 7, the first pressing member 12 is moved in the direction of arrow A in order to position various plate sizes from a large plate to a small plate. Since the long actuator 24 and the long actuators 26, 26 for moving the second pressing members 20, 20 in the direction of the arrow B are required, there is a problem that the equipment cost increases.

When the plate glass 10 is positioned by using a long actuator as in the conventional case, the plate glass 10
There is a problem that the movement amount of the long actuator becomes large depending on the plate size, and there is an unnecessary positioning time. The present invention has been made in view of the above circumstances, and provides a plate-shaped body positioning method and apparatus capable of positioning in a minimum required positioning time regardless of the plate size while reducing equipment costs. The purpose is to provide.

[0008]

The present invention is directed to a traveling frame movably provided on a table, a dedicated carrier movably provided on the traveling frame, or a plate glass cutting movably provided on the traveling frame. The suction means attached to one of the cutter carriers is moved to the suction position of the rectangular plate on the table by the movement of the traveling frame and the carrier, and the rectangular plate is sucked by the suction means. A method for positioning a plate-shaped body, comprising a step of holding and moving the suction means so that two sides of the rectangular plate-shaped body held by suction are in contact with a reference stopper.
It is a device for implementing it.

According to the present invention, the adsorption frame is provided on the table so that the table can travel, a dedicated carrier movably provided on the traveling frame, or a plate glass cutting cutter carrier movably provided on the traveling frame. Attached to one of. Then, the traveling frame and the carrier are moved to move the suction means to the suction position of the rectangular plate-shaped body on the table. Next, the rectangular plate-shaped body is suction-held by the suction means, and the suction means is moved so that the two orthogonal sides of the sucked-held rectangular plate-shaped body come into contact with the reference stopper. As a result, the rectangular plate-shaped body is positioned at the reference position.
