APARATO PARA LA DETECCION DE COLORES DE OBJETOS APLANADOS, EN MOVIMIENTO

摘要

Apparatus for detecting the coloring of moving tiles for the purpose of dividing their flow into a plurality of flows as a function of the quality of their color. The apparatus detects the color of successive portions of the moving tile and breaks down the detected light spectrum into the three primary colors according to the trichromatic theory. The intensity of each primary color is converted into an electric function by a bank of photoelectric sensors, and this function is processed and compared in a microprocessor with coded signals corresponding to the ideal or optimum coloring that the detected tile should present. The microprocessor emits the signals for automating the division of the flow of scanned tiles into a plurality of flows differing in the quality of the coloring of said tiles.
