Title:
SURFACE SHAPE MONITORING DEVICE, ABRASION LOSS MEASURING SYSTEM, AND SURFACE SHAPE MONITORING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/188718
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a surface shape monitoring device which can detect defects in various conveyor belt surfaces with a single inexpensive device, and can reduce operation loss arising from the faulty determination of defects in the conveyor belt surfaces. A surface shape monitoring device according to the present invention, which is a device for monitoring the surface shape of a conveyor belt, is provided with: a line laser which emits a laser beam at a wide angle in the widthwise direction of the surface of the conveyor belt; a camera which captures reflective light of the line laser from the surface of the conveyor belt; a pattern extracting unit which extracts, from the image captured by the camera, a specific pattern drawn by the reflective light; and a location specifying mechanism which specifies the location of a pattern, on the surface of the conveyor belt, which is extracted by the pattern extracting unit, on the basis on an extraction timing, wherein the location specifying mechanism acquires a surface image of the conveyor belt at the specified location.
