tna and industrial metal detection vendor Mettler Toledo Safeline have won a Partnership of the Year award at the recent PPMA Group Industry Awards 2013 from the Processing & Packaging Machinery Association for the hyper-detect metal detector integrated into the tna robag vertical form/fill/seal bagger.
The hyper-detect from tna and Safeline is the world's first non-symmetrical balanced coil metal detector with a conical aperture into the detector. While conventional "throat" metal detectors have long been used in the industry to inspect the product before it enters the bag to allow the use of metallized film, packaging speeds have been limited until now. This integrated design allows the metal detector to be positioned much closer to the multihead weigher, dramatically increasing the speed at which the bagger can produce finished bags. The hyper-detect is extremely sensitive, greatly reducing the risk of contaminants entering the value chain, safeguarding consumer safety and the company's reputation.
The hyper-detect metal detector and bagger integration takes place on two levels. Mechanically, the detector and chute work together to provide a fully optimized path for the product to travel down, offering greater control and repeatability for faster product transfer and reduction in rejects. At the same time, operator control is integrated into the tna robag product and operational screens allow for a single set-up of the whole system, leaving no room for error, and offering real productivity and cost improvements.
