WASTE PLASTIC CONTAINER RECYCLING SYSTEM AND METHOD THEREOF

摘要

A waste plastic container recycling system and a method thereof are provided for determining whether the spectrum of a waste container to be recycled belongs to any one of spectrums of plastic materials and for classifying waste containers of different plastic materials since the plastic materials have the different spectral characteristics. Accordingly, the waste plastic container recycling system and the method thereof can accurately recognize the waste containers of different plastic materials regardless of the appearance, or damage, deformation or concealment of the label on the waste containers.

1. A waste plastic container recycling system, for determining if a waste container is made of one of a plurality of plastic materials so as to recycle the waste container accordingly, including:
a light generator, arranged in a vicinity of the waste container for emitting light to the waste container; a sensing probe, arranged in the vicinity of the waste container and corresponding to the light generator to receive a light signal which is produced from the light entering the waste container or from the light being reflected by the waste container; an optical spectrum analyzer, electrically connected to the sensing probe for receiving the light signal, producing a spectrum of the waste container based on the light signal; a controller, electrically connected to the optical spectrum analyzer, having specific spectrums of respective ones of the plastic materials saved therein, determining if the spectrum of the waste container is identical to any one of the specific spectrums, wherein if the controller determines the spectrum of the waste container is identical to any one of the specific spectrums, a process of recycling the waste container is conducted.
