Method of Monitoring Belt Orientation and/or Belt Travel of A Band Belt Conveyor Apparatus and a Band Belt Conveyor
First Claim
1. A method of monitoring at least one of the parameters consisting of belt orientation and belt travel of a band belt conveyor apparatus, including the following method steps:
- a) measuring at least one of the parameters consisting of compression and thrust stress variation within the belt when passing over a support roller arrangement, b) recording a signal produced by said measurement and associating the signal with a respective given support roller arrangement, the association of a measurement signal with a respective support roller arrangement being effected with calculation of the number and the time spacings of characteristic measurement signals relative to each other having regard to the speed of the belt band, wherein measurement and recording of the signal is effected without the assistance of travel sensors, and c) displaying the signal provided with the positional association for the purposes of detecting at least one phenomenon from the group consisting of misalignment of the belt and defects at the at least one support roller in question.

Abstract
A method of monitoring belt orientation and/or belt travel of a belt conveyor apparatus includes measurement of compression and/or thrust stress patterns within the belt as it passes over a support roller arrangement by measuring means embedded in the belt. The measured signal is recorded and associated with a specific support roller. The signal pattern allows conclusions to be drawn about misalignments of the belt or possible defects in the support rollers. A belt conveyor apparatus has measuring means embedded in the belt and including at least one multi-axis sensor for detecting the stress variations in the belt.

9. A band belt conveyor apparatus for bulk material comprising
a plurality of stations, at least one flexible band belt which in operation passes through said stations thereby forming a load run and an idle run, support roller means between the stations for at least partially supporting the belt, at least one measuring means embedded in the belt for detecting at least one of the parameters consisting of compression and thrust stresses in the belt, said measuring means including at least one multi-axis sensor for detecting at least one of said stress parameters, and means for at least one of the actions consisting of outputting and storing the detected measurement values.
