The need to combine mechanical product handling, precision cameras and optics, high-speed multi-processor electronics, sophisticated processing and operator software, and the pneumatics necessary for accurate defect ejection, challenges the best engineers in the field. Radix have built, and are still building, on their experience won over more than 16 years in the industry and protected by a number of international patents.

Product Handling Radix offer a range of vibratory conveyors, belt or polycord conveyors, their 'Chuteveyor' (a downward-inclined conveyor), and a range of chutes and channelling boards, all to ensure effective product separation and good presentation to the inspection cameras.

Product Inspection Typically we use high-speed, high-resolution, line-scan cameras with wide spectral range and optics to suit an application. Single-sided, and top and bottom cameras, as well as four-camera "all-round" vision are configured to meet the most stringent requirements.

Lighting High-frequency fluorescent lighting for mono-chromatic inspection. Multi-spectral lighting using green, red and infra-red Light Emitting Diodes (LEDs) to detect eg brown discoloration in green product or foreign bodies such as insects. Laser illumination in application-specific combinations of four wavelengths checks the spectral signature of products, detecting contamination which can even be the same colour and shape as the good product.

Electronic Processing Radix have led the field in sorting with their patented parallel digital signal processing (DSP) configuration. The latest 'MC' technology uses DSPs and unique Radix architecture which will process, in four colours and with sub-millimetre resolution, more than 200,000 objects every minute.

Software Simple, menu-driven operator software hides the sophistication of "object" processing configured into the range of Radix "algorithms". Shade and two-, three-, or four-colour processing is supplemented by algorithms able to check dimensions (width, length, height and area), shape, symmetry and many others.

Rejection The Radix ejector valves are extremely reliable, with a life of well over 100 million operations. The ejector nozzle design is dependent on the application and several types are available for optimum ejections. Up to 256 nozzles can be arrayed in a single rejection bank for minimum product wastage. Several rejection banks can be arranged in series for eg length grading (long, medium, short) of products.

Our Project Engineers use full 3-D CAD systems to customise the standard machines or, if necessary, to configure a special machine particular to your application.

Our Sales and Applications Engineers will evaluate your product, carry out free tests in our factory and, if required, take a test machine to your factory for evaluation.
