During automated packaging of fast-moving products in controlled conditions, thermoforming lines produce transparent plastic tray bases from continuous reel-stock material. A small transparent-object sensor with patented UV technology detects the presence of each set of transparent trays after it is formed, initiating a subsequent operation and, optionally, triggering a counting circuit. Manual intervention is avoided,…
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…
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…
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…
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.
