Summary During semi-automated heat staking of assemblies for domestic white goods, manufacturers use light curtains to preserve operator safety without compromising production throughput. The active optoelectronic protective device (AOPD), mounted directly in front of each bench-mounted heat-press, prevents the press-head from descending if it detects any intrusion in the working area, halting the operating cycle immediately. Application Heat-staking is a popular process for fasteni …

Summary 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. Application In the food-processing industry, consumer products generally require s …

Summary During high-volume production of confectionery, sealed cartons of bagged candy travel by conveyor to a labeling station. A versatile photoelectric contrast sensor, mounted beside the conveyor, checks the label alignment and confirms the presence of print markings as each carton leaves the labeling area. If a label is blank, illegible or wrongly positioned, the carton is diverted to a holding area for investigation. Application In the food-processing industry, packaged c …

Summary 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 manual intervention, eliminating the need for unplanned …
