Embodiment Construction

[0028] As shown in FIG. 1 , the photoelectric system 3 as a row camera detects the entire width of the load-bearing surface of the conveyor belt 1 , more precisely using an illumination device 9 . For details of such optoelectronic systems, see the prior art cited at the beginning of this description.

[0029] The two start marks 6 enclose or delimit a limited section of the conveyor belt 1 . Each segment has a length of 10 m to 500 m, in particular each of the same length.

[0030] As far as start tag 6 is concerned, the following variants can be used:

[0031] - The starting mark is formed by at least one notch, a ribbon, a reflective area, a metal particle or a permanent magnet.

[0032] - An initial marker is a code, in particular a code detectable by mechanical, optical, magnetic, conductive or radioactive means. The code is preferably a barcode or similar code marking structure. The code can also consist of small permanent magnets, especially small permanent magnets ...

Abstract

The invention relates to a control device for a conveyor comprising an elastomeric conveyor belt (1) 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 (3) for optically detecting the belt surface, in particular the carrying side thereof in such a way that it is possible to identifya 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 (7) 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 (2), carrying rollers, a supporting structure and, if necessary other components. The inventive device is characterised in that the totality of the conveyor belt (1) is divided into terminal sectors (X) 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 sectors(X) is defined by an initial marking (6) 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 (5)and the first and second sensing units and the encoding unit (5) are connected to the process control computer (7).

Description

technical field [0001] The invention relates to a device for monitoring conveying equipment, comprising: [0002] - Conveyor belts made of elastic material with load-bearing surfaces and running surfaces for conveying the material, wherein the conveyor belts in particular have embedded reinforcements (eg steel cables, textiles). [0003] - optoelectronic systems for optical inspection of the belt surface, in particular of the load-bearing surface, in which damages occurring during operation are recognized and the equipment is stopped when the conveyor belt reaches a critical state, so that repair measures can be taken in good time ; [0004] - a processing computer, which is connected to the optoelectronic system in order to realize the evaluation of all data, wherein the processing computer is in particular connected to the drive control device; and [0005] - Other plant components, ie non-driven wheels, support wheels, support frames and possibly other components.
