CLEARVIEW, a new generation of intelligent X-ray product inspection systems from Safeline AVS, features a colour video display that provides real-time diagnostics data to quality control personnel.

The high-resolution ‘soft ray’ inspection technology is combined with innovative hardware and high-performance image processing software to ensure pharmaceutical, food and packaged product integrity.

Applications include pharmaceuticals, such as blister packaged products, and packages with inserts, and food products, including bulk products such as dried fruits, nuts, spices, and grain; pumpable liquids and slurries; pumpable meat products; conveyed packaged products, discrete packaged items, and loose products.

The ClearView systems ensure pharmaceutical, food and packaged product integrity by detecting and eliminating foreign bodies such as metal, stone, glass, bone, high-density plastic and rubber.

The systems are available in four product models, tailored to the needs of the pharmaceutical, food and packaging industries: the Type 42P automatic pipeline inspection system for inspection of pumped liquids and slurries; the Type 42BF inspection system for inspecting continuous bulk product flows; the Type 42 inspection system (pictured) for automatic inspection of conveyed packages and loose products; and the Type 21 inspection system for high speed automatic inspection of conveyed packaged products.

Using linear technology, critical inspection of any product flowing or conveyed through the systems results from its combination of a computer-controlled soft ray generator and a powerful data analysis system.

The system will detect minute changes in product density that signifies product contamination or deviation from accepted specifications.

Sophisticated image processing software is included to provide rapid analysis, detection and rejection of non-conforming products that do not meet specifications.

An innovative Auto-Learn technology eliminates the need for any set-up, as the system automatically re-calibrates itself as each sample or product is inspected.

Frequent calibration is not required either; the ClearView system automatically analyses product variations and thus continuously achieves optimum inspection sensitivity throughout production.

A stainless steel enclosure cabinet is designed for high-pressure wash down. The system will fit easily into existing conveyor or pipeline systems, and quick release belts or fittings allow quick dismantling and cleaning.

To comply with vendor certification programs and satisfy HACCP or FDA requirements, the ClearView inspection system may be equipped with a statistical control package for automatic data collection.

An available option is a label printout capability that automatically generates labels containing statistical data on a batch.

Each ClearView system is supplied with specific software configurations for the individual customer's application, to inspect for product specification, contaminant, product mass, and damaged items, as needed.

A variety of product reject styles are available; and Autopac Systems, the Australian representative of Safeline AVS, will assist customers in evaluation and specification of the best style reject device for each product and application. Autopac Systems 03 9355 7188.
