Disclosed is a control device and process for aligning, in the running direction, an endless belt. The device comprises a lifting cylinder with a ram which is retracted or extended as a result of switching signals received from microswitches via a control circuit. The device further includes a pivotal wing which is pivoted by the extending ram in the running direction A of the belt, and a deflecting roller having an axle, the ends of which are mounted in the eyeparts of eyebolts. During pivoting, the wing presses one eyebolt, resting at its bolt end against the front side of the wing, in the running direction A of the belt. The axle, mounted at its axle end, with a certain play in the eyepart of the other positionally fixed eyebolt, is pivoted as a result. As soon as the belt runs out of alignment, that is to say deviates from the running direction A, one of the belt edges actuates the associated microswitch and consequently the lifting cylinder. As a result of the pivoting of the axle of the deflecting roller, the non-aligned running of the belt is constantly counteracted and the belt is deflected counter to the nonaligned direction until it actuates the other microswitch. |
