    Abstract: Apparatus for measuring the color of glass, particularly pieces of broken glass relies upon simultaneously measuring the glass transmission in different spectral regions. The glass pieces travel along a conveying path between a light source and a light sensor containing a plural number of optical filters and groups of photoelectric detectors. The groups of photoelectric detectors are disposed at an end face of respective substantially cylindrical tubes. Tube axes enclose an angle and intersect in a conveying plane defined by the conveying path. The optical filters have different spectral transmission regions. Optical lens systems are retained intermediate the respective groups of photoelectric detectors and an opposite end face of the respective tubes. Each optical lens system images the conveying plane at the associated group of photoelectric detectors.

    Abstract: A method and apparatus for sorting bulk material, such as scrap glass, which consists of individual glass parts. Glass scraps are serially fed into a chute and illuminated by a white light source. An optical detector comprising two optical sensors measures optical frequency transmittance data from individual glass scraps, at two frequencies. The two transmittance measurements are logarithmized and a quotient is formed to eliminate the transmittance effect due to glass thickness. The scraps are then classified by a classifier on the basis of the measuring data in accordance with empirically determined classification parameters. The parts are then sorted by a compressed air jet in accordance with the classification. The classification parameters are previously determined by providing a sample of the glass of one color. The measuring data of that sample is determined and optimal classification parameters are then determined on the basis of the measuring data in occurring in the sample.
