Position Detection of Butter Blocks with Reflex Sensors with Background Suppression

For the automatic packaging of blocks of butter in the food industry, it must be ensured that the blocks are correctly placed in the insertion molds of the packaging plant. If the blocks wedge or slide out of the precisely fitting mold, the machine must be cleaned, which is both a time-consuming and costly process. To check the correct position, the stainless steel 316L sensor’s blue light beam is aligned so that it points directly over the packaging film. If the beam is interrupted, the reflex sensor with background suppression switches and immediately stops the system.
