Abstract

SE DESCRIBE UN SISTEMA DE CONTROL MOTRIZ, QUE MANTIENE AUTOMATICAMENTE EL VOLTAJE MOTRIZ DE LA TOBERA DENTRO DE UN MARGEN ADECUADO. EL SISTEMA DE CONTROL MONITORIZA EL ESTADO DE LOS "SATELITES INTERMEDIOS" POSICIONADOS ENTRE GOTAS DE TINTA USADOS PARA IMPRIMIR. CUANDO ESTOS SATELITES NO ESTAN SOBRESALIENDO NI HACIA ADELANTE NI HACIA ATRAS, SE IDENTIFICA UN PRIMER PUNTO CARDINAL DESIGNADO C(L). SE DETERMINA UN SEGUNDO PUNTO CARDINAL C(H) CUANDO EL PUNTO DE INTERRUPCION DE LA GOTA DETIENE LA DISMINUCION, RESPECTO A TAL TOBERA, CON VOLTAJE MOTRIZ EN AUMENTO DE LA TOBERA. PARTIENDO DE LOS DOS VALORES CARDINALES, PUEDE CALCULARSE UNA ESCALA OPERATIVA PARA UNA TINTA PARTICULAR, Y AJUSTARSE AUTOMATICAMENTE EL SISTEMA DE CONTROL. EL VALOR CALCULADO ES ESENCIALMENTE INDEPENDIENTE DE LA TEMPERATURA.A MOTOR CONTROL SYSTEM IS DESCRIBED, WHICH AUTOMATICALLY MAINTAINS THE MOTOR VOLTAGE OF THE NOZZLE WITHIN AN APPROPRIATE MARGIN. THE CONTROL SYSTEM MONITORS THE STATE OF THE "INTERMEDIATE SATELLITES" POSITIONED BETWEEN INK DROPS USED TO PRINT. WHEN THESE SATELLITES ARE NOT PROJECTING FORWARD OR BACKWARD, A FIRST DESIGNATED CARDINAL POINT C (L) IS IDENTIFIED. A SECOND CARDINAL POINT C (H) IS DETERMINED WHEN THE INTERRUPTION POINT OF THE DROP STOPS THE DECREASE, REGARDING SUCH NOZZLE, WITH MOTOR VOLTAGE INCREASING THE NOZZLE. STARTING FROM THE TWO CARDINAL VALUES, AN OPERATING SCALE FOR A PARTICULAR INK CAN BE CALCULATED AND THE CONTROL SYSTEM AUTOMATICALLY ADJUSTED. THE CALCULATED VALUE IS ESSENTIALLY INDEPENDENT FROM THE TEMPERATURE.
