Lock Inspection Systems is to preview its Compact Vertical Fall metal detector for the first time at the forthcoming PPMA, to be held in the NEC, Birmingham, UK this September.
This latest slimline addition to the MET 30+ range follows the introduction of the Compact Waferthin in 2001. Said to be 25 per cent smaller than the previous standard systems, the new Vertical Fall guarantees protection for incoming bulk raw materials in both granular and fine powder form - even in severely restricted spaces.
In designing the Compact Vertical Fall, Lock says that the aim was to create a machine that could detect in all types of raw material, combining a sealed reject mechanism with compact dimensions. The detector's flap reject system offers particular maintenance advantages. It can be cleaned on the spot without having to be removed from the line. There are no nuts or bolts to unscrew, it is sufficient to unclip the hinges and pivot the arm to clean the interior of the pipe. The quick release means less time is wasted on dismantling and resealing the valve.
Measuring 5" (12.7cm) top to bottom, the Compact Waferthin was designed to address the space constraints encountered in the snack food and confectionery industries. Its slim design means it can be slotted into high-speed integrated packaging systems which incorporate multihead weighers feeding vertical form-fill and seal bagmakers.
Lock is also showing its MET 30+ 3f, the first triple fully automatic frequency detector on the market capable of highly accurate inspection of both poly-film and metallised packaged products. The 3f operates at three crystal controlled frequencies - high, medium and low, and features an in-built Automatic Frequency Selection facility which chooses the optimum frequency for the specific product or packaging. When inspecting polywrapped products, for example, the detector will automatically select high frequency, whereas for a product packaged in metallised film it will operate at low frequency.
Lock Inspection Systems supplies metal detection equipment to companies in the food, pharmaceutical and packaging industries for over fifty years. Headquartered in Oldham, UK, with offices in France, the Netherlands and the USA, it has a global network of distributors, maintenance and research teams.
