Abstract

Provided is a conveyor belt wear monitoring system capable of determining the wear condition of an upper rubber cover of a conveyor belt. When the conveyor belt is stopped, on the return side of the conveyor belt, a wear detector with a sensor unit corresponding to an upper cover rubber is disposed, the wear detector is controlled by a control unit to move across an entire length in a belt width direction and the distance from the sensor unit and a surface of the upper cover rubber is detected, the detected data is received by a calculation unit, and an amount of wear of the upper cover rubber is calculated on the basis of the received data.

First claim

The invention claimed is:

1. A conveyor belt wear monitoring system comprising:
a wear detector disposed corresponding to an upper cover rubber of a conveyor belt, the wear detector including a rotary roller;
a control unit that controls movement of the wear detector; and
a calculation unit that receives detection data from the wear detector; wherein
when the conveyor belt is stopped, the wear detector is controlled by the control unit to move across an entire length in a belt width direction with the rotary roller rolling in contact with the upper cover rubber and detect an amount of wear of the upper cover rubber.

2. The conveyor belt wear monitoring system according to claim 1 , wherein the wear detector is disposed at a plurality positions spaced apart from each other in a longitudinal direction of the conveyor belt.

3. The conveyor belt wear monitoring system according to claim 1 , further comprising a contact member disposed spaced apart in a belt thickness direction from the rotary roller in contact with the upper cover rubber, wherein the rotary roller and the contact member sandwich the conveyor belt with the contact member in contact with a lower cover rubber.

4. The conveyor belt wear monitoring system according to claim 3 , wherein the contact member is an elongated body that extends the entire length in the belt width direction.

5. The conveyor belt wear monitoring system according to claim 3 , wherein the contact member is a moving roller that moves in sync with the rotary roller.

6. The conveyor belt wear monitoring system according to claim 1 , wherein the wear detector is moved back and forth at least across the entire length in the belt width direction.
