Plate glass attitude changing device and attitude changing method

摘要

PROBLEM TO BE SOLVED: To stably rotate a plate glass even when a working fluid remains on a top face of the plate glass.SOLUTION: A posture change device 2 of a plate glass G comprises a support body 6 for bending and supporting the plate glass G so as to project upward; a lifting device 7 for lifting the support body 6; and a rotating device 8 for rotating the support body 6. By bending and supporting the plate glass G so as to project upward by the support body 6, a working liquid can be dropped from the plate glass G even if the working liquid remains on a top face of the glass sheet G after end face processing, breakage of the plate glass G can be prevented, and the plate glass G can be stably rotated.SELECTED DRAWING: Figure 3
