Patent ID: 8366030

Claim:
A selective collection system for recyclable containers, comprising: a housing part to house internal components of the selective collection system; a control device to control overall operation of the selective collection system; an input device installed on the front of the housing part to receive an input material; a material identification device to identify an input material and to transmit a corresponding material identification signal to the control device, which identifies the input material based on the material identification signal, wherein the material identification device comprises: a front side plate; a back side plate; a pair of downward sloping stands inserted into two shafts that rotate between the front side and back side plates to open the pair of downward sloping stands after the material identification device identifies the input material and transmits the corresponding material identification signal to the control device, and to close the pair of downward sloping stands when the material identification device is identifying the input material; a metal detect sensor to sense the input material on the pair of downward sloping stands and transmits a metal detect signal to the control device; and two load cells, installed below the pair of downward sloping stands, to weigh the input material on the pair of downward sloping stands and to transmit the weight datum to the control device; wherein the control device determines whether the input material on the pair of downward sloping stands is a metal based on the metal detect signal; and a sorting guide device to route the input material received from the material identification device based on identification of the input material by the control device to one of the following devices: a shredding device to shred the input material dropped from the sorting guide device and identified as a polyethylene terephthalate (PET) bottle by the control device; a compressing device to compress the input material dropped from the sorting guide device and identified as an aluminum can by the control device; and a collection part comprising three collection bins into which shredded, compressed, or unprocessed input materials are deposited, respectively, the input material identified as being neither a PET bottle nor an aluminum can by the control device is dropped from the sorting guide device without any processing into a collection bin storing the unprocessed input material.
