Abstract

SE PRESENTA UN SISTEMA DE INSPECCION PARA MUESTREAR Y DETERMINAR LA PRESENCIA DE RESIDUOS DE CONTAMINANTES DENTRO DE MATERIALES DE PLASTICO A RECICLAR A PARTIR DE MATERIALES DE PLASTICOS USADOS TALES COMO BOTELLAS DE BEBIDAS O ENVASES DE ALIMENTOS, EL SISTEMA INCLUYE UN APARATO DE ASPIRACION, O ALTERNATIVAMENTE UN ESCANER OPTICO, PARA DETECTAR LOS CONTAMINANTES A MEDIDA QUE LOS MATERIALES DE PLASTICO SON MOVIDOS RAPIDAMENTE A LO LARGO DE UN TRANSPORTADOR MAS ALLA DE UNA SERIE DE ESTACIONES. LAS BOTELLAS DE ALIMENTO O BEBIDAS RECICLADAS SON SUMINISTRADAS A TRAVES DE UNA PICADORA EN LINEA CON EL TRANSPORTADOR Y EL MATERIAL DE LAS BOTELLAS DESMENUZADO ES SUMINISTRADO A UNA MAQUINA LAVADORA. LAS BOTELLAS Y EL MATERIAL DESMENUZADO PUEDE SER COMPROBADO EN BUSCA DE CONTAMINANTES EN CUALQUIER UBICACION EN UN PROCESO EN LINEA. EN UN EJEMPLO LAS BOTELLAS SE COMPRUEBAN PRIMERO ANTES DE SU ENTRADA AL INTERIOR DE LA PICADORA PARA SEPARAR LAS BOTELLAS QUE CONTENGAN CONTAMINANTES GRUESOS. DESPUES EL MATERIAL DESMENUZADO QUE SALE DE LA PICADORA ES COMPROBADO EN BUSCA DE CONTAMINANTES A UNA ELEVADA TEMPERATURA PROVOCADA POR EL PROCESO DE DESMENUZAMIENTO Y LOS MATERIALES CONTAMINADOS SON CLASIFICADOS O SEPARADOS DEL MATERIAL NO CONTAMINADO. EN TERCER LUGAR, LOS MATERIALES SON DE NUEVO COMPROBADOS EN BUSCA DE CONTAMINANTES A MEDIDA QUE EMERGEN DE LA MAQUINA LAVADORA UNA VEZ MAS SACANDO PARTIDO DE LA ELEVADA TEMPERATURA DE LOS MATERIALES QUE CONDUCE A LA EMISION DE VAPORES POR LOS CONTAMINANTES. LOS MATERIALES CONTAMINADOS SON SEPARADOS DE NUEVO DE LA MATERIA NO CONTAMINADA APORTADA QUE SE UTILIZARA PARA LA FABRICACION DE BOTELLAS PARA ALIMENTOS O BEBIDAS.
