Abstract

METODO Y EQUIPO PARA REGULAR EL PUNTO DE RETENCION (N SUB P) DE UN TRATAMIENTO POR PRESION EXTENDIDA. POR MEDIO DEL METODO, LA DISTRIBUCION DE LA PRESION DEL TRATAMIENTO TRANSVERSAL DEL TEJIDO DE MATERIAL (W) QUE PASA A TRAVES DEL PUNTO DE RETENCION (N SUB P) SE CONTROLA UTILIZANDO UNA SERIE DE ELEMENTOS DE FUERZA. EN EL METODO SE UTILIZA UN SISTEMA DE REGULACION (100, 200, 300, 400) POR MEDIO DEL CUAL LAS FUERZAS EFECTIVAS DE LOS ELEMENTOS DE FUERZA SE REGULAN POR SEPARADO. ADEMAS, SE CREA UN MODELO MATEMATICO QUE ILUSTRA EL PUNTO DE RETENCION (N SUB P) QUE SE VA A REGULAR Y EL TEJIDO (W) QUE SE VA A TRATAR. SE DETERMINA UNA DISTRIBUCION DE VALOR PREDETERMINADO Q(Z) DEL PERFIL DE PRESION DEL PUNTO DE RETENCION, DONDE Z= 1...N Y (N) ES ELEGIDA COMO SUSTANCIALMENTE MAYOR QUE EL NUMERO (K) DE LOS ELEMENTOS DE FUERZA AJUSTABLES SEPARADAMENTE O LOS GRUPOS DE ELEMENTOS DE FUERZA. SEGUN EL MODELO MATEMATICO, SE PROGRAMA UN BLOQUE DE CONVERSION DE ZONA (120), CUYAS CANTIDADES DE ENTRADA CONSISTENEN PRESIONES DE LINEA DETERMINADAS (Q SUB 1...Q SUB N) Y CUYAS CANTIDADES DE SALIDA CONSISTEN EN VALORES PREDETERMINADOS DE PRESION DE ZONA (P SUB 1....P SUB K). LA CONVERSION DE ZONA SE PROGRAMA DE TAL MANERA QUE PUEDE LOGRARSE UN PERFIL DE CARGA LINEAL DEL TEJIDO DE MATERIAL (W) CUYAS DESVIACIONES DEL PERFIL DE VALOR DETERMINADO Q(Z) SE MINIMIZAN. LOS VALORES DETERMINADOS DE PRESION DE ZONA CONVERTIDOS (P SUB 1....P SUB K) PASAN A UNA UNIDAD INTELIGENTE DE REGULACION (300) QUE TIENE DIAGNOSTICO Y PROTECCION PARA FORMAR VALORES DETERMINADOS (B) PARA PRESIONES DE ZONA. CADA UNO DE LOS ELEMENTOS DE FUERZA O GRUPOS DE ELEMENTOS DE FUERZA DEL PUNTO DE RETENCION (N SUB P) QUE VAN A REGULARSE SE REGULA POR SEPARADO POR MEDIO DE VALORES DETERMINADOS (B).
