Abstract

SE PRESENTA UN SISTEMA PARA CLASIFICAR PARTICULAS DE DESECHO BASADO EN EL COLOR, EL SISTEMA INCLUYE UNA CINTA TRANSPORTADORA OPACA (22) PARA TRANSPORTAR PARTICULAS DE DESECHO DE FORMA Y ORIENTACION ALEATORIAS A TRAVES DE UN AREA DE VISION (24) EN LA CUAL SE DETECTAN UNA SERIE DE IMAGENES MEDIANTE UN DETECTOR DE IMAGENES (26). UN SENSOR DE POSICION (30) DETERMINA EL AVANCE LINEAL DE LAS PARTICULAS DE DESHECHO Y TRANSMITE SEÑALES A UN CONTROLADOR DETECTOR DE IMAGENES (32), QUE EMITE PERIODICAMENTE UNA SEÑAL DE CONTROL A UN PROCESADOR DE IMAGENES (34) PARA ADQUIRIR UNA IMAGEN DEL AREA DE VISION (126) Y PARA DIVIDIR LA IMAGEN EN UNA MATRIZ DE CELDAS (128) EN DONDE LOS PIXELES SATISFACEN UN CRITERIO PREDETERMINADO, Y SE ESTABLECE UNA SEÑAL DE DISCRIMINACION PARA CADA CELDA. UN CONTROLADOR SEPARADOR (36) QUE RECIBE LAS SEÑALES DEL DISCRIMINADOR ACTIVA SELECTIVAMENTE LA PARTE APROPIADA DE UN SEPARADOR (38) PARA SEPARAR LAS PARTICULAS DESEADAS DE LAS NO DESEADAS. EL SISTEMA TAMBIEN INCLUYE UN DISPOSITIVO HUMEDECEDOR (41) CORRIENTE ARRIBA DEL AREA DE VISIONADO (24) PARA ROCIAR LIQUIDO SOBRE LA SUPERFICIE DE LA CINTA TRANSPORTADORA (22) PARA CREAR UNA SUPERFICIE OSCURECIDA, MAS UNIFORME COMO FONDO.
