Abstract

LAS PIEZAS MEZCLADAS DE DIFERENTES METALES NO FERREOS SE CLASIFICAN INICIALMENTE HACIENDO PARAR LAS PIEZAS A TRAVES DEL INFLUJO DE UN CAMPO MAGNETICO DE ALTA DENSIDAD Y VARIACION RAPIDA, PARA, INMEDIATAMENTE A CONTINUACION, DEJARLAS CAER LIBREMENTE A TRAVES DE UNAS TRAYECTORIAS INCLINADAS HACIA ADELANTE Y HACIA ABAJO, CUYA DIRECCION ESTA DETERMINADA POR EL MOMENTO DE LAS PIEZAS, LA FUERZA DE LA GRAVEDAD Y LAS FUERZAS REPULSIVAS QUE SE GENERAN EN LAS PIEZAS COMO CONSECUENCIA DEL CAMPO MAGNETICO. LA MAGNITUD DE LAS FUERZAS MAGNETICAS INDUCIDAS DIFIERE DE UNOS METALES NO FERREOS A OTROS, DE MODO QUE LA LONGITUD DE LAS TRAYECTORIAS DE LAS PIEZAS DE FORMA Y TAMAÑO SIMILAR PERO DISTINTO METAL VARIAN. DE ESTA FORMA LAS PIEZAS DE DIFERENTES METALES SON SEPARADAS. EL CAMPO MAGNETICO ES PRODUCIDO POR UN RODILLO HUECO DE HIERRO CON IMANES FIJOS SOBRE SU SUPERFICIE EXTERIOR, DE EJE HORIZONTAL, Y REFRIGERADO POR LIQUIDO, QUE GIRA RAPIDAMENTE. LOS IMANES SE COLOCAN EN FILAS FORMADAS POR NUMEROSOS IMANES PERMANENTES DE PEQUEÑO TAMAÑO QUE SON POSICIONADOS JUNTANDO LOS POLOS DEL MISMO SIGNO. UNA CINTA TRANSPORTADORA, QUE MUEVE LAS PIEZAS POR ENCIMA DEL CILINDRO, TIENE SU POLEA DE DESCARGA RODEANDO EL CILINDRO COAXIALMENTE DE MANERA QUE LAS PIEZAS CAEN LIBREMENTE DESDE EL FINAL DE LA CINTA TRANSPORTADORA DESPUES DE PARAR A TRAVES DEL CAMPO MAGNETICO. POR LO TANTO, LAS LONGITUDES DE LAS TRAYECTORIAS PUEDEN SER CONTROLADAS AJUSTANDO LA VELOCIDAD DE LAS PIEZAS, YA QUE SE MODIFICA DE ESTA FORMA EL MOMENTO DE LAS PIEZAS, Y AJUSTANDO LA VELOCIDAD DE GIRO DEL RODILLO, QUE MODIFICA LA FRECUENCIA DE LOS CAMBIOS EN EL CAMPO MAGNETICO Y, CONSECUENTEMENTE, LA MAGNITUD DE LAS FUERZAS REPULSIVAS INDUCIDAS.
