Conveyor belt tension control has a tensioning drum to deflect the path of the lower level with a setting unit and a process computer to modify the nominal tension value according to the current working conditions

摘要

In the appts. to optimize the belt tension forces in longitudinal conveyor belts, a tensioning drum (1) with a setting system (2) deflects the path of the lower level of the belt round it. The nominal value for the optimum belt tension force is calculated by a process computer (3) from the flow of the current belt loading data (m) and a comparison of the actual energy take-up (E) at the drive motors, so that the required drive capacity of the drive (5) is changed in the direction of the min. requirement.
