Title:
OUTPUT DEVICE, AND MACHINE TOOL
Document Type and Number:
WIPO Patent Application WO/2023/144873
Kind Code:
A1
Abstract:
The objective of the present invention is to provide an output device capable of employing a threshold to detect an operating state of an operating device capable of holding a target object, and a machine tool provided with the output device. The output device comprises: an actuator; an output member which is displaced in an axial direction on the basis of the drive of the actuator, thereby operating the operating device to hold the target object; a detected member which is displaced in the axial direction in accordance with the axial-direction displacement of the output member; a distance sensor which outputs a detection signal corresponding to a distance to the detected member; and a control device into which the detection signal from the distance sensor is input. The detected member has an inclined surface of which a distance to the distance sensor decreases with increasing distance from one side to the other side in the axial direction. The distance sensor outputs to the control device the detection signal corresponding to the distance to the inclined surface. The control device includes: an acquiring unit which acquires a threshold; and a determining unit which, on the basis of the threshold acquired by the acquiring unit, determines a detected value indicated by the detection signal output form the distance sensor, and detects the operating state of the operating device.
