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. If the bottle is not to be crushed, and is refundable, the microprocessor causes another door to open, opposite to the crusher entrance, and the bottle is collected in one piece in another bin. If the bottle is not refundable, it is returned to the customer. In the event the bottle is refundable, a coupon is printed and released by the apparatus for each bottle inserted in the machine.
