Abstract
The invention relates to a device for correcting the run of a belt automatically, in particular, for item sorting systems, having a rotatable adjusting roller which can be adjusted in its inclination, wherein, via a lever arm of the adjusting roller mount and a spring force acting on the lever arm, a torque is generated at the rotary axis to adjust the inclination of the adjusting roller. This torque compensates for the torque which is exerted on the adjusting roller mount via the adjusting roller by the belt tension during a centered run of the belt. The angle of wrap at the adjusting roller, its direction of inclination, the direction of the run of the belt, the tangential direction of the belt at the adjusting roller as well as the spring path and the characteristic spring curve of the spring element are selected such that, in the event of the inclination of the adjusting roller due to the change of moment resulting from an off-center belt run, a directional component opposite to the off-center direction of deflection is imparted to the belt on the adjusting roller.
