Method and measurement system for detecting and localizing incorrect positioning of support rollers in belt conveyor installations

A method for determining and localizing incorrect alignments of support rollers (1) of a support roller station (13) in a belt conveyor installation containing a belt (2), the method comprising the steps of:

• placing a number of pressure sensors (4) detachably and without damaging the belt (2) in a line and at a height transversely over the belt width on the underside of the belt (2), wherein the number of the pressure sensors (4) corresponds to at least the number of the support rollers (1) of the support roller station (13) to be measured,
• capturing, with the pressure sensors (4), measurement signals of contact pressure in contact with the support roller (1) as the pressure sensors (4) pass over a support roller (1) of a support roller station (13), and,
• determining an alignment of the support rollers on the basis of characteristics of pressure point patterns thereby obtained from the captured measurement signals,
• wherein said measuring system can be detachably connected to the belt (2) of the belt conveyor installation and can be used for mobile measurements on more than one belt conveyor installation.
