Abstract: The apparatus consists of a machine for refunding glass bottle deposits, crushing the bottle and sorting the crushed glass as to color, either clear, brown or green. The bottle has a label provided with an optically read bar code which identifies the bottle's 1) color, 2) whether it must be returned to the manufacturer in one piece, and 3) whether a refund is, in fact, due for the particular bottle. The bottle is inserted in the apparatus and the bar code on the bottle passes beneath an optical scanner. If the bottle is refundable and of a particular color (i.e., clear, green, brown), a microprocessor electrically connected to the scanner activates a door and a deflector causing the bottle to fall into a glass crusher including a bin provided with a rotating plate which smashes the bottle. A chute beneath the glass crusher is positioned by the microprocessor so that the crushed glass is conveyed to one of three collection bins depending on the sensed color.

Abstract: An improved glass crushing apparatus for a reverse bottle vending, crushing and sorting machine having an opentop, rotatable receptacle mounted at the top of the bin for catching the bottle to be smashed in the bin. After receipt of the bottle, the receptacle is rotated by a stepping motor controlled by the microprocessor and the bottle is dropped onto and smashed by a rotating impeller which contacts and throws the bottle against a reinforced, sharp corner of the bin. The crushed glass or glass cullet is then collected in a predesignated collection bin.
