A cost efficient and reliable method for online sorting of special glass which works independent of the color of glass and the shape of the material. The scrap glass stream to be detected is thereby irradiated by UV absorption or transmission values of the scrap glass stream, more specifically of the material-specific UV absorption edges and 'UV-cutoff' frequencies, with reference values obtained before from standardized material laboratory inspections. If special glass is being detected, blowing nozzles disposed downstream of a detector unit divert the special glass toward a predetermined location where it is deposited. There can also be a system which includes a radiation source, a detection unit, an evaluation and control unit and a removal apparatus.

Method for detecting and sorting glass

The invention relates to a detection device for identifying objects in a material stream, preferably a cullet stream. The device comprises several light sources, which emit light in a rectilinear manner, preferably diode light sources and which are combined to form at least one optical emitter, at least one receiver that contains a lens system and a photoelectric cell, in addition to a detection section, which is located between the emitter and the receiver and is traversed by the material stream. The aim of the invention is to provide a detection device, which eliminates to a great extent the error sources that are inherent in optical lens systems. To achieve this, the light sources of an emitter are directed onto the area of intersection of the optical axis of the lens system with the lens system of the receiver that is assigned to the emitter.
