Applied Color Sensor Based Solution for Sorting in Food Industry Processing
The market of food products is growing significantly, and this affects commercialization and potential consumption aspects. Sorting is mandatory from efficiency and precision approaches in production. Our paper presents a simple and cost effective solution for presenting a sorter automaton (self-operating machine), with applied sensorics. The idea is to apply a color sensor (TCS3200) which analyzes any type of product by its color and sort it for the production line with the help of the servo- and stepper motors. The system will be controlled by a simple card computer. The color sensor detects the frequency of the wavelength reflected from the product and give the information to the processing logic, which translates the 3D RGB cube based data. Then the logic makes a conversion to HSL (hue, saturation, lightness) derived in degrees [0°, 360°]. The investigation of the machine has been implemented for an exemplary colored candy sorting. The resulting colors of the analyzed samples are selected in a specific calibration set of numbered color ranges. The proposed automaton and its validation are presented in details.
