Brittle material breaking apparatus and brittle material breaking method

Abstract

Provided are a brittle material breaking apparatus and a brittle material breaking method wherein a brittle material can be broken while continuously moving the brittle material, and the brittle material can be surely broken without alignment of a scribe line with a blade, positional correction and the like. The width of a brittle material (11) to be broken is wider than a distance between moving rollers (13, 14) in a direction substantially orthogonally intersecting with an advancing direction of the brittle material (11). A scribe line (18) of the brittle material (11) is formed substantially parallel to the advancing direction of the brittle material (11), on one end portion or on the both end portions positioned outside the moving rollers (13, 14). The pressurizing rollers (15, 15) are provided on the one end portion or on the both end portions where the scribe lines (18, 18) are formed outside the positions where the moving rollers (13, 14) are brought into contact with the brittle material (11). While the brittle material (11) exists in a region where the brittle material is to be moved by a plurality of the rollers (13, 14), the pressurizing rollers (15, 15) are pressed down to the side of the brittle material (11).

Description

technical field [0001] The present invention relates to a brittle material breaking device and a brittle material breaking method, capable of continuously moving the brittle material and cutting the brittle material even for a brittle material such as a glass plate in which the scribe lines are formed approximately parallel to the moving direction. The side sections are disconnected. Background technique [0002] After the scribe line is formed on a plate-shaped brittle material such as a glass plate, the brittle material can be broken along the scribe line by applying a predetermined load to the brittle material. [0003] For example, Patent Document 1 discloses a breaking device capable of cutting a brittle material such as a glass plate on which a scribe line is formed by moving a blade (blade) up and down by an actuator driven by a servo motor or the like. Cut beautifully without cracking. The brittle material is moved to a predetermined position by the sliding table a...

AI Technical Summary

Problems solved by technology

Therefore, breaking cannot be performed continuously, and there is a problem that it is difficult to shorten the time required for the breaking process as the number of glass plates to be broken increases.

[0006] In addition, in order to accurately break, it is necessary to accurately align the scribing line and the blade, and by additionally providing an alignment sensor such as a camera to correct the position, there is a problem that the overall mechanism of the device becomes complicated and the cost increases. question
