Long-range photoelectric sensor counts shrink-wrapped carton packs during high-volume packing operations

During high-volume confectionery packaging operations, conveyors deliver stacked cartons to shrink-wrapping stations. At each station, a wrapping machine encloses a stack in heat-shrink film and an infrared oven shrinks the film to form a sealed pack of cartons. A long-distance through-beam photoelectric sensor, mounted beside the conveyor, senses the presence of each pack as it…
