Filling machines are widespread in many industries, including solids handling, chemical, food, beverage and pharmaceutical, often operating continuously around the clock. Industrial sensors detect containers, lids, labels and caps, measure fill levels and more, and play a vital role in keeping automated filling equipment running reliably, accurately and with minimal downtime.
During confectionery packaging operations, conveyor lines deliver preformed cardboard cartons to packing stations. At each station, a pick-and-place packing robot packs layers of bagged candy in cartons. Once filled, cartons are conveyed to case-sealing stations. A highly reliable retro-reflex photoelectric sensor, mounted beside the line, senses each carton as it arrives at the packing station, halting the conveyor and initiating the packing sequence once it is correctly positioned.
During secondary packaging of bags of confectionery, manufacturers arrange bags in overlapping layers. Multi-axis pick-and-place packing robots align and pack layers of bags in preformed cardboard cartons. The filled cartons are conveyed to case-sealing stations. A highly reliable photoelectric sensor, mounted directly above the conveyor, senses the height of the top layer of bags in each carton before sealing and rejects insufficiently filled cartons
In a bottling plant, filled bottles are capped and then shrink-wrapped together to produce rigid packs of bottles. A missing cap or bottle is a serious quality fault that must be eliminated reliably.
Food-grade washdown inductive sensors from Swiss manufacturer Contrinex are completely compatible with the strict hygiene standards of the dairy industry, helping maximize plant utilization during round-the-clock production of milk-based foodstuffs. Rated to IP68/IP69K, Contrinex stainless-steel washdown sensors withstand both aggressive cleaning chemicals and high-pressure water jets, offering highly robust solutions for the harshest operating environments. Food-grade sensors are available with IO-Link, a standardized serial connection protocol, providing digital communication in washdown areas at no additional cost.
