Abstract:
A device for monitoring a tubular belt conveyor system comprising:a conveyor belt made of elastomeric material with embedded tie rods, longitudinal edges, an open section and a closed section wherein the longitudinal edges have a desired overlap to form a tubular belt with an overlap area; a driving drum; a reversing drum; support rollers; guide rollers; and supporting structures; wherein said device comprises an optoelectronic system mounted where the closed section meets the open section for monitoring the overlap area comprising at least one light source whose light beam is aligned with the overlap area, said optoelectronic system, if deviation from the desired overlap occurs, initiating a corrective setting by means of the guide rollers and, it the desired overlap does not occur within a preset period of time, effecting an automatic shutdown of the tubular belt conveyor system.
