Integrated label counting for timely coil changeovers

Fast and precise labeling of the packaging is crucial when using a side loader. The fork sensors from SICK are especially suited for this application and allow ultrahigh process speeds. Being a smart sensor, the WFS fork sensor can do even more: with its integrated “Counting and Debouncing” smart task, it also counts the labels that have been unwound from the coil and compares this to the total number of labels on the coil. Based on this information, the sensor sends a timely signal to the machine controller as soon as the labels are about to run out. The machine operator can then prepare for the coil changeover. This enables machine downtimes to be minimized and unplanned stops to be avoided, while at the same time reducing the load on the controller.
