Abstract

A conveyor belt apparatus (10) is provided with a wear measuring device (12) that measures an amount of wear of a surface (11a) of a conveyor belt (11) on which transport material has been loaded, and with a revolution counting device (14) that counts a number of revolutions of the conveyor belt (11).

Claims

1. A conveyor belt apparatus comprising:

an endless belt-shaped conveyor belt that transports transport material; and

a wear measuring device that measures an amount of wear of a surface of the conveyor belt on which the transport material has been loaded, wherein

there is provided a revolution counting device that counts a number of revolutions of the conveyor belt.

2. The conveyor belt apparatus according to claim 1, wherein

there is provided a revolution detecting device that detects a start and a finish of each revolution of the conveyor belt, and

the revolution counting device counts the number of revolutions by adding one revolution to the number of revolutions made by the conveyor belt each time one revolution has finished based on detection data from the revolution detecting device.

3. The conveyor belt apparatus according to claim 2, wherein

the wear measuring device is formed by a magnetic sensor that measures as the amount of wear a magnetic field of a first magnetic field generating device that has been installed on the conveyor belt, and

the revolution detecting device detects as the start and finish of one revolution of the conveyor belt a magnetic field of a second magnetic field generating device that is installed on the conveyor belt, and

the wear measuring device also functions as the revolution detecting device.

4. The conveyor belt apparatus according to claim 3, wherein the polarities of the respective magnetic fields of the first magnetic field generating device and the second magnetic field generating device are mutually different on the surface side of the conveyor belt.
