Sorting device for classifying items/work pieces in a stream of material has an optical receiver to identify items to be sorted and an optical transmitter as a source of light

摘要

An optical receiver (1) identifies items to be sorted. An optical transmitter (2) acts as a source of light. Between the optical transmitter and the optical receiver there is a through-passage, preferably designed as a free-fall section (8), for the items to be sorted. The optical receiver has a telecentric lens system (12).
