Abstract

SE DESCRIBE UNA MAQUINA IMPRESORA POR IMPACTOS SUCESIVOS DE TIPO MEJORADO, DISEÑADA PARA REDUCIR LA GENERACION DE RUIDOS DEBIDOS A IMPACTOS DURANTE SU FUNCIONAMIENTO. LA MAQUINA IMPRESORA INCLUYE UNA PUNTA DE IMPRESION QUE PUEDE DESPLAZARSE RESPECTO A UN RODILLO DEFORMABLE, CON UN ELEMENTO DE IMPRESION, UNA CINTA DE IMPRESION Y UNA HOJA RECEPTORA DE IMAGEN INTERCALADA ENTRE LA PUNTA DE IMPRESION Y EL RODILLO, QUE SE DESPLAZAN EL UNO HACIA EL OTRO DURANTE UN PERIODO DE CONTACTO CONTROLADO. EL MOVIMIENTO ESTA SOMETIDO AL CONTROL POR UN MECANISMO CINETICO DE ACCIONAMIENTO QUE APLICA UNA PRIMERA FUERZA PARA DESPLAZAR LA PUNTA DE IMPRESION RESPECTO AL RODILLO, ANTES DE INICIAR EL PERIODO DE CONTACTO, CON EL FIN DE CERRAR EL INTERVALO ENTRE ELLOS, Y A CONTINUACION APLICAR UNA SEGUNDA FUERZA PARA ACELERAR EL DESPLAZAMIENTO DE LA PUNTA DE IMPRESION RESPECTO AL RODILLO, DESPUES DE LA INICIACION DEL PERIODO DE CONTACTO, PARA HACER QUE LA PUNTA DE IMPRESION DEFORME EL RODILLO.
