Abstract
A chip sorting apparatus is disclosed. The apparatus includes an article transport mechanism, a light source positioned to direct light across surfaces of transported articles, and a detector positioned to detect light reflected from such surfaces and emit signals each indicative of a spectrum of light reflected by one such article as such articles are transported. A signal analyzer compares detector signals with stored data representative of the colors of articles of a set of articles being sorted. The analyzer emits article identifying signals reflective of such comparison. The apparatus also includes a sorter which is responsive to such identifying signals and directs identified articles from the transport mechanism into appropriate ones of a set of collection stations. A method of sorting a set of articles according to color is also disclosed.
