Title:
WEAR DETECTION DEVICE AND METHOD FOR CONVEYOR BELT
Document Type and Number:
WIPO Patent Application WO/2023/132096
Kind Code:
A1
Abstract:
Provided are a wear detection device and a method enabling efficient grasping of a degree of wear on a surface of a conveyor belt with high versatility at low cost. Embedded bodies 2 embedded at intervals in a conveyor belt 17 in a longitudinal direction each include: a passive-type IC tag 3 arranged at one end portion in a width direction of the conveyor belt 17; a linear detection element 7 that is connected to the IC tag 3 and extends from the one end portion to the other end portion in the width direction of the conveyor belt 17 to form a loop circuit 9. An embedding depth from the surface of the conveyor belt 17 of the loop circuit 9 is set in advance, and a transmission electric wave W1 is sent from a detector 10 toward the IC tag 3. Using information from the IC tag 3 transmitted to the detector 10 by a response electric wave W2 sent from the IC tag 3 in response to this transmission electric wave W1, an arithmetic operation unit 13 determines whether or not the loop circuit 9 is energized. On the basis of a result of this determination, a degree of wear on the surface of the conveyor belt 17 within a range where the loop circuit 9 is embedded is grasped.
