Abstract
Official abstract text for this publication.
A rubber magnet ( 3 ) includes a plate-like diagonal portion ( 21 ) and a plate-like parallel portion ( 22 ) which are both magnetized in a thickness direction, the diagonal portion ( 21 ) extending in a conveyor belt width direction while linearly extending, in section in a conveyor belt length direction, from an outer side end ( 3 b ), which is closer to the front-side surface ( 2 a ), to an inner side end ( 3 a ), which is away from the front-side surface ( 2 a ), while being at an angle to the front-side surface ( 2 a ), the parallel portion ( 22 ) being formed continuously from the inner side end ( 3 a ) of the diagonal portion, so as to be arranged parallel to the front-side surface ( 2 a ).
First claim
Opening claim text (preview).
The invention claimed is: 1. A conveyor belt wear detection apparatus, comprising: a rubber magnet embedded in a conveyor belt; a magnetic sensor which is disposed in proximity to a front-side surface forming an outer peripheral surface of the conveyor belt and detects a magnetic field from the rubber magnet; and an arithmetic section for estimating, based on a signal from the magnetic sensor, a wear amount on the front-side surface of the conveyor belt, wherein the rubber m…
