Title:
BREAKING DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/090179
Kind Code:
A1
Abstract:
Provided is a breaking device with which even in a case of repeatedly performing breaking, breaking can be desirably performed whenever the breaking is performed. The present invention has: a motor that rotates inside a horizontal surface; a movement conversion mechanism that converts a rotary movement of the motor into an ascending/descending movement of a breaking bar; a motor control unit that controls the operation of the motor; a torque detection unit that detects the torque acting on the motor; and a breaking processing unit for performing breaking on a breaking target object by controlling the operations of respective parts of the breaking device. In a state in which the breaking target object is placed and fixed to a support part while one main surface thereof is brought into contact with the support part, the breaking bar is lowered toward the other side main surface of the breaking target object, that is, a position corresponding to a scribing line formation position by rotating the motor by means of the motor control unit. It is determined that the breaking of the breaking target object is completed on the basis of a change in the torque detected by the torque detection unit when the breaking bar is being lowered.
