Title:
DEVICE AND METHOD FOR DETECTING LONGITUDINAL TEAR IN CONVEYOR BELT
Document Type and Number:
WIPO Patent Application WO/2022/004055
Kind Code:
A1
Abstract:
Provided are a detection device and method whereby it is possible to accurately detect the presence or absence of a longitudinal tear in a conveyor belt, while having high versatility and low cost. An embedded body 2, which has one antenna 4 and a passive IC tag 3, connected to the one antenna 4, at one end of a coaxial cable 6 and the other antenna 5 at the other end, is embedded in a conveyor belt 17 with the one antenna 4 and IC tag 3 spaced apart from the other antenna 5 in the width direction and with the coaxial cable 6 extended in the width direction. A calculation unit 12 determines whether or not a detector 10 has received the radio wave R2 transmitted from the IC tag 3 through the coaxial cable 6 and the other antenna 5 in response to the radio wave R1 transmitted from the detector 10 to the other antenna 5, and detects, on the basis of the determination result, the presence or absence of a longitudinal tear in the conveyor belt 17 in the area where the coaxial cable 6 is embedded.
