Presence Check of Biscuits in Packaging Machines with Reflex Sensors with Background Suppression

After cookies are made in the food industry, they must be separated, sorted and portioned before packaging. The presence of the biscuit stacks must be checked in the fully automated packaging machines. Mounted above the conveyor line, two compact reflex sensors with background suppression detect the irregular surfaces of the biscuits at high speed, switching frequencies of up to 1,000 Hz and regardless of the background condition. The sensors can be easily adjusted thanks to the visible red light.
