LATERAL RUNNING BEHAVIOUR OF CONVEYOR BELTS

摘要

Correct guiding is of major importance in the operation of belt conveyors. Faults such as incorrect geometry, uneven load distribution or belt splicing cause lateral movement of the running belt. The running behaviour of the belt is largely dependent on its deformation at the point where it meets the drums. For precise automatic control, it is necessary to know the belt position, the inclination between drum and running direction and the curvature of the belt at this point. This data is also necessary in order to check the accuracy of the mechanical models developed to simulate the running behaviour of the belt. This paper deals with the lateral running behaviour of the belt on a skewed tail pulley as well as a conical tail pulley. Belt deformations were recorded by a CCD camera as well as by conventional potentiometer distance sensors. The resultant measurements were compared with the mechanical models.
