Conveyor system with system for detecting the state of wear and tear and/or defects and respective method

A conveyor system for conveying materials, comprising:

• a transmission assembly comprising a closed transmission chain composed of a plurality of links interconnected to each other, said transmission assembly further comprising a drive shaft operatively connected to said transmission chain for a motion transfer;
• a conveyor element connected to said chain and designed for conveying said materials;
• a detection system for detecting wear and/or defects, operatively connected to said transmission assembly and designed to detect the state of wear and/or defects of said transmission assembly, said detection system comprising a sensor operatively connected to said transmission assembly and equipped with a data transmission module, and a control unit, in communication with said sensor, designed to receive data from said sensor and to detect a state of wear and/or defects of said transmission assembly,
• wherein said transmission assembly comprises a target link constituting or comprising part of said sensor, said target link comprising an optical or electromagnetic target that is detected by a fixed sensor, or detector, capable of detecting optically or electromagnetically such target, for the purpose of determining the state of wear and/or the position and/or speed of said target link.
