Abstract
A method for optimizing the running properties of a rotating belt of a weighing belt conveyor includes, for at least one rotation of the belt, determining a unique reference position on the belt. A force signal is determined in dependence on the movement of the belt with respect to the reference position during the at least one rotation. From this force signal, the course of a deviation of the force signal from a set value as a consequence of a disruptive force is determined. At least in correspondence with the direction of the determined deviation, the mass of the belt is increased or reduced at locations in dependence on the position of the belt with respect to the reference position.
Claims16
A method including:
- (a) for a conveyor belt of a conveyor belt system, defining a reference position along the length of the conveyor belt;
- (b) during at least one rotation of the conveyor belt in a rotation direction, determining a force signal in dependence on the movement of the reference position;
- (c) determining a course of deviation of the force signal from a set force value as a consequence of a disruptive force from the rotation of the conveyor belt;
- and
- (d) changing the mass of the conveyor belt at locations along the length of the conveyor belt, the change in the mass of the conveyor belt at each location being at least in correspondence with a direction of the determined deviation of the force signal at that location.
A device including:
- (a) a detector configured to detect a reference position along the length of a conveyor belt of a conveyor belt system;
- (b) a sensor configured to output a force signal over a course of at least one rotation of the conveyor belt by the conveyor belt system;
- and
- (c) an evaluation unit configured to (i) receive the force signal and determine a course of a deviation of the force signal from a set force value in dependence on the position of the conveyor belt relative to the reference position, and to (ii) determine at least a direction of the deviation in dependence on the position of the conveyor belt relative to the reference position to facilitate changing the mass of the conveyor belt at locations along the length of the conveyor belt at least in correspondence with the direction of the determined deviation of the force signal at the respective location.
