Vision

Trichromatic RGB sensing

The supplied T20 Square and COMMANDOR Square brochures describe 5,400 × 3 RGB sensing. Illumination, image acquisition and camera settings bring visible material differences into view.

Recognition

Process the visible details

COMMANDOR Square describes analysis of colour, shape and brightness, with study-data classification. RIGG specializes in size and hole recognition.

Separation

Turn a decision into action

Classification and timed air-jet ejection separate the selected material. Chute and belt platforms present different materials for inspection.

The hardware behind the concepts.

A closer look at sensing, programmable processing and mechanical design. The sensor photograph and processor illustration explain the concepts; the engineering photograph comes from MARK.

Generic programmable processor cutaway illustrating a silicon die, bond wires and internal interconnections — FPGA processing
A field-programmable gate array is a programmable processing device. Parallel logic can handle image data and classification tasks with consistent timing; the FPGA processes sensor signals rather than sensing light itself.

Mechanical design of a MARK sorting machine at the engineering workstation — Mechanical engineering
The frame, feed system, chutes and collection paths shape how material moves through the machine. Mechanical design brings these elements together so inspection, separation, access and maintenance fit the intended process.

How a sorting decision happens.

01
Present the material
An even product stream gives the inspection system a consistent view.
02
Illuminate & capture
Lighting and RGB imaging reveal visible differences in each product.
03
Process & classify
The machine compares colour or image features against its sorting settings.
04
Time the separation
A synchronized rejection signal directs unwanted material away from the accepted stream.

A general explanation of optical sorting. Hardware, recognition features and settings vary by model. Consult the official technical documents for your selected machine.
