DEVICE FOR CUTTING GLASS PLATE

摘要

A device for cutting a glass plate, which device is capable of cutting even a thick glass plate resistant to cracking (development of split), along a cutting line. The device comprises: a sucking disk unit (21) to lift the glass plate (1); a support table (39) to support the glass plate flat; cutting mechanisms (9, 10); a first transfer unit to transfer said cutting mechanisms on the polar coordinate plane on the glass plate surface; a glass plate receiving body (37) to support the glass plate in a position opposite to said cutting mechanisms and a cracking unit (38) to exercise cracking; a second transfer unit to transfer said glass plate receiving body and cracking unit on the polar coordinate plane on the glass plate surface; and a control unit to control cutting operation of the cutting mechanisms, operation of the first and second transfer units, and cracking operation of the cracking unit.
