System for the automatic detection of load cycles of a machine for the transferring of loads

摘要

The present invention relates to a system for the automatic detection of load cycles of a machine for the transferring of loads, wherein the machine includes a lifting apparatus for the raising of the load and a transport apparatus for the horizontal movement of the load, comprising: a load change detection for the automatic detection of a load change at least on the basis of the output signals of a lifting force measurement apparatus, a load position detection which detects the position of the load in at least a horizontal direction and a load cycle detection for the automatic detection of a load cycle, wherein the load cycle detection takes place at least on the basis of the output signals of the load change detection and of the load position detection. In accordance with the invention, the load cycle detection stores the position of the load as the load pick-up point when a positive load change was recognized and evaluates the positive load change as the start of a new load cycle on the basis of a query as to whether the load has been moved a predetermined distance from the load pick-up point in the horizontal.
