Title:
BEND-BREAKING JIG AND BEND-BREAKING PROCESS METHOD
Document Type and Number:
WIPO Patent Application WO/2023/119728
Kind Code:
A1
Abstract:
[Problem] To provide a bend-breaking jig that, in a bend-breaking process, makes it possible to easily change the rolling direction of a bend-breaking cutter wheel to the direction in which an imaginary scribe line of an edge part of a glass plate extends, without the use of a θ axis servo motor or transmission member (pulley, belt, etc.). [Solution] In first and second bend-breaking jigs 83a, 83b, a cutter wheel axis O3 extending in the vertical direction of a bend-breaking cutter wheel 92 is eccentric in a radially outward direction with respect to a cutter holder center axis O2 extending in the vertical direction of a bend-breaking cutter holder 91, and the bend-breaking cutter wheel 92 is rotatable 360° about the cutter wheel axis O3 with respect to the bend-breaking cutter holder 91. The first and second bend-breaking jigs 83a, 83b, by travelling slightly in a prescribed direction on the upper surface of an edge part of a glass plate and in parallel with the upper surface, cause the bend-breaking cutter wheel 92 which contacts the upper surface of the edge part of the glass plate to rotate about the cutter wheel axis O3, such that the rolling direction of the bend-breaking cutter wheel 92 is the same as the travelling direction of the bend-breaking jigs 83a, 83b.
