Method and device for removing flat packages from a pile

摘要

The invention pertains to a method for removing flat mail pieces from a pile by means of a removal device with controllable removal velocity which feeds the mail pieces to conveyor belts driven at the velocity v0. Set velocity value profiles are associated with the differences between set and actual gaps. Since the curve forms are selectable, the drive ratios can be taken into account. The association of the set velocity value curves of the drive unit with the actual gaps in order to achieve the set gap at the takeover point of the conveyor belts at velocity v0 takes place in previous measurements.The nonlinearities of the transfer function of the drive unit are detected by tabular assignment of the velocity profiles on the basis of measurements.
