Title:
DEVICE AND METHOD FOR DETECTING LONGITUDINAL TEAR IN CONVEYOR BELT
Document Type and Number:
Japanese Patent JP2023101223
Kind Code:
A
Abstract:
To provide a detection device and method which can accurately detect whether or not a longitudinal tear occurs in a conveyor belt, while having high versatility and achieving low cost.SOLUTION: Embedded bodies 2 which are embedded at intervals in a longitudinal direction in a conveyor belt 17 each include: a passive-type IC tag 3 arranged at one end portion in the width direction of the conveyor belt 17; and a linear detection element 7 which 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. A transmission electric wave W1 is transmitted from a detector 10 toward the IC tag 3. Information from the IC tag 3 is sent to the detector 10 by a response electric wave W2 transmitted from the IC tag 3 in response to the transmission electric wave W1. It is determined by an arithmetic section 13 whether or not the loop circuit 9 is energized, by using the information. On the basis of the result of the determination, it is detected whether or not a longitudinal tear occurs in the conveyor belt 17 in a range where the loop circuit 9 is embedded.SELECTED DRAWING: Figure 4
