Description
Sistema de aplicación de vacío en mesas de impresoras por proyección.Vacuum table application system projection printers.
La presente invención está relacionada con los procesos de impresión sobre superficies rígidas o semirrígidas, mediante proyección de tinta, proponiendo un sistema de aplicación de vacío para sujetar las piezas a imprimir, sobre las mesas de las impresoras, de forma que dicho vacío no influya sobre la tinta que se proyecta para la impresión.The present invention is related to printing processes on rigid or semi-rigid surfaces, by ink spray, proposing an application system vacuum to hold the pieces to be printed on the tables of the printers, so that this vacuum does not influence the ink that It is projected for printing.
Para la impresión sobre superficies rígidas o semirrígidas es conocida la técnica de contacto mediante rodillos de impresión, así como la técnica sin contacto mediante cabezales de proyección, siendo esta última de mayor perfección y calidad para la aplicación de las tintas.For printing on rigid surfaces or semi-rigid roller contact technique is known of printing, as well as the technique without contact by means of heads projection, the latter being of greater perfection and quality for the application of the inks.
Es conocida también la práctica de sujetar las piezas destinadas a ser imprimidas, sobre la mesa de las máquinas impresoras, mediante una aplicación de vacío a través de la propia mesa, la cual puede ser fija o formada por una cinta transportadora, determinándose para ello dicha mesa con una superficie de apoyo de las piezas perforada, para aplicar a través de ella el vacío de sujeción de las piezas.It is also known to hold the parts intended to be printed on the machine table printers, by means of a vacuum application through the own one table, which can be fixed or formed by a tape conveyor, determining this table with a support surface of the perforated parts, to apply through of her the emptiness of subjection of the pieces.
Ocurre sin embargo que generalmente las piezas a imprimir son de una anchura menor que la superficie de la mesa de apoyo, con lo cual en las zonas laterales no cubiertas por la pieza de aplicación se produce un efecto de absorción por el vacío que puede provocar el desvío de la tinta que se proyecta sobre la pieza a imprimir, dando lugar a imperfecciones de la impresión sobre la pieza y la pérdida de una parte de la tinta proyectada.It happens however that generally the pieces to print are of a width less than the table surface of support, which in the lateral areas not covered by the piece of application there is a vacuum absorption effect that it can cause the ink to be diverted on the part to print, resulting in imperfections of the print on the piece and the loss of a part of the projected ink.
De acuerdo con la invención se propone un sistema de aplicación del vacío en las mesas de las impresoras, con una disposición que anula la actuación del vacío por las zonas no cubiertas por la pieza a imprimir, evitando así la influencia perjudicial del vacío para la impresión y las pérdidas de tinta desaprovechada.According to the invention, a vacuum application system on printer tables, with a provision that cancels the performance of the vacuum in the areas not covered by the piece to be printed, thus avoiding the influence harmful vacuum for printing and ink losses wasted
Según este sistema de la invención, por debajo de las zonas laterales de la superficie de la mesa de apoyo de las piezas a imprimir se disponen unos limitadores de obturación de las perforaciones de la mesa, yendo dichos limitadores incorporados en montaje de desplazamiento en el sentido transversal de la mesa.According to this system of the invention, below of the lateral areas of the surface of the support table of the parts to be printed are provided with shutter limiters of the table perforations, said limiters incorporated in sliding assembly in the transverse direction of the table.
Se obtiene así una disposición con la que los limitadores cierran el paso de la aspiración del vacío por las zonas laterales de la mesa en la que apoyan las piezas a imprimir, evitando que el efecto de dicha aspiración pueda tener influencia sobre la tinta que se proyecta para realizar la impresión sobre la pieza dispuesta para ser imprimida.A provision is thus obtained with which the limiters close the vacuum aspiration passage through the lateral areas of the table on which the pieces to be printed support, preventing the effect of such aspiration from having an influence on the ink that is projected to make the impression on the piece ready to be printed.
La movilidad de los limitadores permite además regular la posición de los mismos para ajustar su colocación en relación con las zonas laterales de la mesa que no quedan cubiertas por la pieza a imprimir en cada caso, es decir que se puede adaptar la zona de actuación del vacío a través de la mesa en función de la anchura de las piezas a imprimir, para que sobre ellas actúe la mayor fuerza de fijación sobre la mesa, pero sin que haya escapes de vacío que puedan afectar a la tinta que se proyecta para la impresión.The mobility of the limiters also allows regulate their position to adjust their placement in relationship with the side areas of the table that are not covered for the piece to be printed in each case, that is to say that it can be adapted the area of action of the vacuum across the table depending on the width of the pieces to be printed, so that the greater fixing force on the table, but without leaks of vacuum that may affect the ink that is projected for Print.
Por todo ello, dicho sistema de la invención resulta de unas características ciertamente ventajosas, adquiriendo vida propia y carácter preferente para la función de aplicación a la que se halla destinado en relación con las mesas de impresoras que disponen de una aplicación de vacío para fijar las piezas a imprimir.Therefore, said system of the invention results of certain advantageous characteristics, acquiring own life and preferred character for the application function to which is intended in relation to the printer tables that have a vacuum application to fix the pieces to to print.
La figura 1 muestra esquemáticamente el sistema de la invención en una mesa de impresora, según un ejemplo de realización.Figure 1 schematically shows the system of the invention on a printer table, according to an example of realization.
El objeto de la invención se refiere a un sistema destinado para evitar las pérdidas de vacío en las mesas de impresoras por proyección de tinta, en las que la sujeción de las piezas (1) a imprimir se realiza mediante aplicación de vacío a través de la mesa (2) de apoyo de dichas piezas (1) destinadas para ser imprimidas.The object of the invention relates to a system designed to prevent vacuum losses at tables of inkjet printers, in which the holding of The pieces (1) to be printed are made by vacuum application to through the support table (2) of said parts (1) intended for be printed
El sistema consiste en la disposición de unos
limitadores (3) a modo de placas, por debajo de la superficie (4)
de transmisión del vacío a la mesa (2) provista con perforaciones
(5), sobre la que se colocan las piezas (1) a imprimir, desde una
cámara (6) a la que se suministra el vacío mediante un sistema de
aspiración (7), siendo la disposición igualmente válida para mesas
(2) fijas, o para mesas (2) formadas por una cinta transportadora
dotada de movimiento longitudi-
nal.The system consists of the provision of limiters (3) as plates, below the surface (4) of transmission of the vacuum to the table (2) provided with perforations (5), on which the pieces are placed ( 1) to be printed, from a chamber (6) to which the vacuum is supplied by a suction system (7), the arrangement being equally valid for fixed tables (2), or for tables (2) formed by a conveyor belt endowed with longitudinal movement
nal.
Los limitadores (3) se disponen en el montaje con libertad de desplazamiento en el sentido transversal respecto de la mesa (2) de apoyo de las piezas (1), de forma que mediante dicho desplazamiento los limitadores (3) pueden situarse de manera que cubran por debajo las partes laterales de la mesa (2) que no quedan cubiertas por la pieza (1) dispuesta sobre ella para ser imprimida.The limiters (3) are arranged in the assembly with freedom of movement in the transverse direction of the table (2) supporting the pieces (1), so that by said displacement the limiters (3) can be positioned so covering underneath the side parts of the table (2) that do not are covered by the piece (1) arranged on it to be printed.
De este modo, la aplicación del vacío solo afecta a la parte de la mesa (2) cubierta por la pieza (1), lográndose un buen efecto de la fijación de dicha pieza (1) por la acción del vacío, en tanto que por las zonas laterales de la mesa (2) que no queda cubiertas por la pieza (1) no se produce absorción con efecto a través de la mesa (2), con lo cual la tinta que se proyecta desde los cabezales (8) para realizar la impresión, no resulta afectada y por lo tanto no se alteran las condiciones de la proyección que se aplica para la impresión de la pieza (1).Thus, the application of vacuum only affects the part of the table (2) covered by the piece (1), achieving a good effect of fixing said piece (1) by the vacuum action, while on the side areas of the table (2) that is not covered by the part (1) no absorption occurs with effect across the table (2), whereby the ink that is project from the heads (8) to make the impression, not it is affected and therefore the conditions of the projection that is applied for the printing of the piece (1).
El movimiento de los limitadores (3), para regular su posición en función de la anchura de las piezas (1) a imprimir, puede realizarse manualmente, o bien ir dotado de un accionamiento automático, sin que ello altere el concepto del sistema, que es la obturación de las zonas laterales de la mesa (2) no cubiertas por las piezas (1) a imprimir, para que la absorción del vacío de fijación de las piezas (1) sobre la mesa (2) no tenga un efecto perjudicial para la impresión.The movement of the limiters (3), to adjust its position according to the width of the pieces (1) a print, can be done manually, or be equipped with a automatic actuation, without altering the concept of system, which is the sealing of the side areas of the table (2) not covered by the pieces (1) to be printed, so that the absorption of the fixing vacuum of the pieces (1) on the table (2) do not have a detrimental effect on printing.
