Conveyor belt device with a particular belt-steering device

摘要

Conveyor belt device comprising a relatively long and narrow belt. In order to ensure the correct positioning of the belt over great distances, steering rollers are provided which are arranged transversely opposite one another in the direction of transport of the belt. The steering rollers are embodied such that the upper side thereof is level with the upper side of the parts of the conveying belt run which are situated further upstream and further downstream, respectively. Viewed in the transverse direction, the steering rollers close the belt in on both sides between grooves provided for that purpose. The bottoms of the grooves are at a distance which is greater than the width of the belt in said location and the surface of the steering rollers which engages with the belt run is of conical design. This ensures that the position of the belt run is automatically corrected.
