Transparent-object sensors with patented UV technology detect presence of clear plastic sheet during thermoforming

During automated packaging, high-speed thermoforming lines produce transparent plastic blister-trays from continuous reel-stock material. Transparent-object sensors with patented UV technology detect the presence of the transparent plastic sheet as it is unwound, ensuring the material is correctly tensioned as it enters the loading station. False detection is avoided, ensuring reliable operation with little or no…

Miniature Ecolab-certified photoelectric sensor detects presence of cheese portions in high-volume food processing

During high-volume production of individually packaged cheese portions, conveyors deliver product to packaging stations. In-line buffering stations regulate flow to match packaging throughput; miniature Ecolab-certified sensors detect the presence of each portion after buffering, triggering the packaging cycle. Sensitivity parameters for each portion size, stored on the sensor’s inbuilt memory, may be updated remotely without…

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…

Miniature photoelectric sensor detects presence of bagged candy during secondary packaging operations

During high-speed production of retail items, a confectionery manufacturer conveys individual bags of candy to a pick-and-place packing robot for secondary packaging. A highly reliable diffuse-mode photoelectric sensor, mounted beside the conveyor, detects the presence of bags as they approach the packing station and inhibits the pick-and-place sequence if no bags are queued for packing.
