The invention relates to a control device for a conveyor comprising an
elastomeric conveyor belt which is provided with a carrying side for
transporting material and a pulley side and comprises, in particular an
embedded strength support, an optoelectronic system for optically
detecting the belt surface, in particular the carrying side thereof in
such a way that it is possible to identify a damage during functioning
and to stop the conveyor in the case of a critical situation of the
conveyor belt and timely repair it, a process control computer which is
connected to said optoelectronic system and used for evaluating all data
and interacts, in particular with a traction control, and different other
elements of the conveyor, namely a non-driven drum, carrying rollers, a
supporting structure and, if necessary other components. The inventive
device is characterised in that the totality of the conveyor belt is
divided into terminal sectors and each sector is provided with a distinct
address in such a way that the sector marking is formed and the detection
of each marking is carried out in a contactless manner by means of a
first sensing unit, each of the sections is defined by an initial marking
whose detection is also contactlessly carried out by means of a second
sensing unit, the movable element of the conveyor is provided with an
encoding unit and the first and second sensing units and the encoding
unit are connected to the process control computer.
