Abstract: A bend-breaking jig changes a rolling direction of a bend-breaking cutter wheel in bend-breaking processing. In first and second bend-breaking jigs, a cutter wheel axis extending in an up-down direction of the cutter wheel is eccentric radially outward with respect to a cutter holder center axis extending in an up-down direction of a bend-breaking cutter holder. The cutter wheel is rotatable by 360° in a direction around the cutter wheel axis with respect to the cutter holder. When the first and second bend-breaking jigs slightly travel on an upper surface of an edge part of a glass plate in a predetermined direction in parallel with the upper surface, the cutter wheel abutting on the upper surface of a glass plate edge part rotates in the direction around the cutter wheel axis, and a rolling direction of the cutter wheel becomes the same as a traveling direction of the bend-breaking jigs.

Abstract: A bend-breaking system, after a cutter wheel forms an end cutting line at an edge portion of a glass plate, the cutter wheel is raised by a holder raising/lowering mechanism. A first pressing member is lowered by the first pressing member raising/lowering mechanism to sandwich a main body portion and the edge portion of the glass plate between the first pressing member and the first and second support members. A second support member is lowered by the second support member raising/lowering mechanism, and the second pressing member is lowered by the second pressing member raising/lowering mechanism to press the edge portion of the glass plate extending to an outer side of a contour cutting line downward while maintain the sandwiching of the main body portion and bend-breaks the edge portion. The bend-breaking system smoothly and reliably bend-breaks an edge portion of a glass plate to be processed in bend-breaking processing.

Abstract: A glass plate processing system includes a first aligning means. When first and second glass plates different upper and lower surface areas are processed, the first aligning means aligns a first side edge extending in a front-rear direction on one side in a width direction of a first glass plate to be processed first with a first side edge extending in the front-rear direction on the one side in the width direction of a second glass plate to be processed later. The glass plate processing system causes the first aligning means to align the first side edge of the second glass plate at a position of the first side edge of the first glass plate to perform processing on the second glass plate. The glass plate processing system shortens a moving distance and arrival time for a processing device and shortens cycle time of processing.
