SISTEMA DE BOMBEO DE TINTA PARA IMPRESORAS Sector de la tecnicaINK PUMPING SYSTEM FOR PRINTERS Technical sector
La presente invencion esta relacionada con la alimentacion de tintas en maquinas impresoras, particularmente las de tipo flexograficas, proponiendo un sistema de bombeo de tinta para dichas maquinas, con el cual se consigue un perfecto control del caudal de la tinta que se bombea.The present invention is related to the feeding of inks in printing machines, particularly those of flexographic type, proposing an ink pumping system for said machines, with which a perfect control of the flow of the ink being pumped is achieved.
Estado de la tecnicaState of the art
Las maquinas de impresion flexografica necesitan un control del flujo de la tinta que se emplea, ya que, debido a la velocidad de la impresion, si no llega suficiente tinta a los medios de impresion el color de la impresion resulta deficiente, mientras que si llega demasiada tinta se obtiene un indeseado exceso o rebose de la tinta que ensucia la maquina de impresion.Flexographic printing machines need control of the flow of the ink used, since, due to the speed of printing, if not enough ink reaches the print media, the color of the print is poor, while if it arrives Too much ink you get an unwanted excess or overflow of the ink that soils the printing machine.
Por ello, es necesario que en dichas maquinas de impresion se produzca un bombeo de la tinta de impresion a caudal constante y que dicho caudal se pueda regular para adaptarlo a las necesidades de cada impresion.Therefore, it is necessary that such printing machines produce a pumping of the printing ink at a constant flow rate and that said flow rate can be regulated to adapt it to the needs of each printing.
Para esa funcion de bombeo de las tintas de impresion es conocida la utilizacion de bombas volumetricas de engranajes, las cuales permiten impulsar un volumen constante de las tintas; pero debido a que las tintas de impresion son productos abrasivos, al estar en contacto con los engranajes de las bombas los deterioran. Por otro lado, al final de cada proceso de utilizacion de las maquinas impresoras hay que limpiarlas, ya que si no los restos de las tintas utilizadas se secan y bloquean el mecanismo de bombeo. Y ademas las tintas de impresion no son lfquidos limpios, sino que llevan partfculas abrasivas en suspension, las cuales pueden tambien bloquear el mecanismo de bombeo asf como desgastarlo. Estos inconvenientes resultan de particular relevancia, ya que este tipo de bombas son de diffcil y costosa reparacion.For this function of pumping printing inks, the use of volumetric gear pumps is known, which allow to drive a constant volume of the inks; but because the printing inks are abrasive products, being in contact with the gears of the pumps deteriorate them. On the other hand, at the end of each process of using the printing machines it is necessary to clean them, since if not the remains of the inks used are dried and block the pumping mechanism. And also the printing inks are not clean liquids, but instead have abrasive particles in suspension, which can also block the pumping mechanism as well as wear it. These drawbacks are of particular relevance, since these types of pumps are difficult and expensive to repair.
Se conoce tambien la utilizacion de bombas de diafragma, de accionamiento neumatico, conThe use of pneumatic-operated diaphragm pumps is also known, with

las cuales las tintas de impresion no entran en contacto con el mecanismo de accionamiento de las bombas, sino solamente con los diafragmas de las mismas, los cuales son faciles de cambiar si se estropean por la abrasion. Sin embargo, el volumen de las tintas a mover es pesado, y en tanto que el aire de accionamiento del sistema de bombeo es compresible, el caudal de la tinta que se bombea no es constante. Para tratar de compensar dicha desventaja de forma que el flujo sea constante, se requiere el empleo de electronica altamente costosa en las maquinas de impresion flexografica.which printing inks do not come into contact with the pump drive mechanism, but only with their diaphragms, which are easy to change if they are damaged by abrasion. However, the volume of the inks to be moved is heavy, and while the operating air of the pumping system is compressible, the flow rate of the ink being pumped is not constant. To try to compensate for such a disadvantage so that the flow is constant, the use of highly expensive electronics in flexographic printing machines is required.
Objeto de la invencionObject of the invention
De acuerdo con la presente invencion se propone un sistema de bombeo, con el cual se puede bombear tinta en las maquinas impresoras con un perfecto control de caudal constante, siendo ademas el caudal regulable, y en unas condiciones de perfecta seguridad frente a componentes electricos de la maquina de impresion.In accordance with the present invention, a pumping system is proposed, with which ink can be pumped into the printing machines with a perfect constant flow control, the flow rate being also adjustable, and in conditions of perfect safety against electrical components of The printing machine.
Este sistema de bombeo objeto de la invencion comprende una bomba de diafragma, en combinacion con una bomba volumetrica con engranajes que impulsa un fluido no compresible, preferentemente un lfquido, tal como agua o aceite, mediante el cual se actua el accionamiento de la bomba de diafragma que es la que bombea directamente la tinta.This pumping system object of the invention comprises a diaphragm pump, in combination with a volumetric pump with gears that drives a non-compressible fluid, preferably a liquid, such as water or oil, by means of which the pump drive is actuated. diaphragm which is the one that directly pumps the ink.
De este modo la tinta que se bombea es impulsada por la bomba de diafragma, la cual es actuada sin alteraciones del accionamiento, con independencia del volumen de tinta a impulsar, ya que el medio de accionamiento de dicha bomba es incompresible y ademas dicho medio es impulsado de una manera constante por la bomba volumetrica con engranajes.In this way the ink that is pumped is driven by the diaphragm pump, which is operated without alterations of the drive, regardless of the volume of ink to be driven, since the means of actuation of said pump is incompressible and in addition said means is constantly driven by the volumetric pump with gears.
Por otro lado, con este sistema las tintas de impresion a bombear no entran en contacto con el mecanismo de la bomba volumetrica con engranajes, con lo cual se evita el problema de abrasion de los elementos de dicha bomba y, por lo tanto, los costes elevados de reparacion o sustitucion de la misma; no siendo necesaria tampoco por tanto una limpieza de los engranajes cada vez que se utiliza la maquina impresora, para evitar que el secado de los restos de las tintas utilizadas puedan atascar esa bomba volumetrica con engranajes.On the other hand, with this system the printing inks to be pumped do not come into contact with the mechanism of the volumetric pump with gears, which avoids the problem of abrasion of the elements of said pump and, therefore, the costs high repair or replacement thereof; It is therefore not necessary either to clean the gears each time the printing machine is used, to prevent drying of the remains of the inks used to clog that volumetric pump with gears.
Regulando la velocidad de giro de los engranajes de la bomba volumetrica, se puede controlar, por otra parte, la cantidad de tinta que se bombea, permitiendo asf una sencilla yBy regulating the speed of rotation of the gears of the volumetric pump, on the other hand, the amount of ink that is pumped can be controlled, thus allowing a simple and

Por todo ello, el sistema de la invencion resulta de unas caractensticas muy ventajosas para la funcion de bombeo de tintas de impresion a la que esta destinado, adquiriendo vida propia y caracter preferente respecto de los sistemas convencionales que se utilizan convencionalmente para la misma aplicacion.Therefore, the system of the invention results from very advantageous features for the function of pumping printing inks to which it is intended, acquiring its own life and preferential character with respect to conventional systems that are conventionally used for the same application.

Descripcion detallada de la invencionDetailed description of the invention
El objeto de la invencion se refiere a un sistema de bombeo, para el bombeo de tinta (1) en maquinas impresoras, particularmente para maquinas impresoras flexograficas, aunque con caracter general es de aplicacion en cualquier maquina de impresion que requiera un suministro de caudal constante de las tintas (1) de impresion.The object of the invention relates to a pumping system, for the pumping of ink (1) in printing machines, particularly for flexographic printing machines, although in general it is applicable in any printing machine that requires a constant flow supply of printing inks (1).
El sistema segun la invencion tiene unos medios impulsores que comprenden una bomba de diafragma (2), en combinacion con una bomba volumetrica (3) con engranajes (13), en donde la bomba volumetrica (3) esta configurada para impulsar un fluido (4) no compresible, preferentemente un lfquido, tal como agua o aceite, de manera que mediante el fluido (4) impulsado por la bomba volumetrica (3) con engranajes (13) se actua el accionamiento de la bomba de diafragma (2), la cual impulsa la tinta (1) que se tiene que bombear.The system according to the invention has driving means comprising a diaphragm pump (2), in combination with a volumetric pump (3) with gears (13), wherein the volumetric pump (3) is configured to drive a fluid (4 ) not compressible, preferably a liquid, such as water or oil, so that by means of the fluid (4) driven by the volumetric pump (3) with gears (13) the actuation of the diaphragm pump (2) is actuated, the which drives the ink (1) that has to be pumped.
La bomba de diafragma (2) tiene unas membranas (5), dispuestas cada una de ellas entre una primera camara (6) de llenado con el fluido (4) que es impulsado por la bomba volumetrica (3), y una segunda camara (7) que se llena con la tinta (1) a bombear, la cual llega por una entrada (8) y sale por una salida (9).The diaphragm pump (2) has membranes (5), each arranged between a first chamber (6) filled with the fluid (4) that is driven by the volumetric pump (3), and a second chamber ( 7) which is filled with the ink (1) to be pumped, which arrives through an inlet (8) and exits through an outlet (9).

limitativo representado en las figuras, la bomba de diafragma (2) tiene un embolo (10) portador de las membranas (5) en sus extremos, estando dispuestas dichas membranas (5) entre las respectivas primeras camaras (6) comunicadas con la bomba volumetrica (3) y las respectivas segundas camaras (7) de tinta (1) que comunican con la entrada (8) comun de llegada de la tinta (1) y la salida (9) comun de envfo de la tinta (1), disponiendo cada una de las segundas camaras (7) de unas valvulas (11) y (12) unidireccionales en la comunicacion con la entrada (8) y con la salida (9), respectivamente.limiting represented in the figures, the diaphragm pump (2) has a plunger (10) carrying the membranes (5) at its ends, said membranes (5) being arranged between the respective first chambers (6) communicated with the volumetric pump (3) and the respective second cameras (7) of ink (1) that communicate with the ink inlet (8) common (1) and the ink outlet (9) common (1), providing each of the second cameras (7) of unidirectional valves (11) and (12) in communication with the inlet (8) and with the outlet (9), respectively.
Con dicha realizacion, como se observa en la figura 1, cuando el fluido (4) impulsado por los engranajes (13) de la bomba volumetrica (3) llega a la primera camara (6) de una de las membranas (5) de la bomba de diafragma (2), dicha membrana (5) se desplaza hacia la respectiva segunda camara (7) del otro lado de la misma, provocando en dicha segunda camara (7) una presion que hace que la valvula (11) respectiva de comunicacion con la entrada (8) cierre el paso impidiendo la llegada de tinta (1) y que la valvula (12) respectiva de comunicacion con la salida (9) abra el paso para el envfo de tinta (1); mientras que por el mismo efecto de desplazamiento y moviendose de manera sincronizada por la union con el embolo (10), la otra membrana (5) se desplaza haciendo que en la respectiva segunda camara (7) se produzca una depresion que hace que la valvula (12) respectiva de comunicacion con la salida (9) cierre el paso de tinta (1) y que la valvula (11) respectiva de comunicacion con la entrada (8) abra el paso de tinta (1), llenandose esa segunda camara (7) de tinta (1).With said embodiment, as seen in Figure 1, when the fluid (4) driven by the gears (13) of the volumetric pump (3) reaches the first chamber (6) of one of the membranes (5) of the diaphragm pump (2), said membrane (5) moves towards the respective second chamber (7) on the other side thereof, causing in said second chamber (7) a pressure that causes the respective communication valve (11) with the inlet (8) close the step preventing the arrival of ink (1) and that the respective valve (12) of communication with the outlet (9) open the passage for the ink envelope (1); while for the same displacement effect and moving in synchronized manner by the union with the plunger (10), the other membrane (5) moves causing a depression in the respective second chamber (7) that causes the valve (12) respective communication with the outlet (9) close the ink passage (1) and that the respective valve (11) communicate with the input (8) open the ink passage (1), filling that second chamber ( 7) ink (1).
En un inmediato ciclo subsiguiente del proceso de bombeo, como se observa en la figura 2, se modifica la direccion del fluido (4) que es impulsado por los engranajes (13) de la bomba volumetrica (3), enviandose dicho fluido (4) hacia la respectiva primera camara (6) de la membrana (5) cuya respectiva segunda camara (7) se encuentra llena de tinta (1), con lo cual se produce un ciclo inverso al anterior, es decir se vacfa la segunda camara (7) que se encuentra llena, enviando la tinta (1) por la salida (9), mientras que la segunda camara (7) de la otra membrana (5) se llena de tinta (1) que llega por la entrada (8). De este modo, repitiendose continuamente ciclos inversos como los mencionados, se obtiene un bombeo continuo de tinta (1), con un caudal constante que se puede regular variando la velocidad de giro de los engranajes de la bomba volumetrica (3).In an immediate subsequent cycle of the pumping process, as seen in Figure 2, the direction of the fluid (4) that is driven by the gears (13) of the volumetric pump (3) is modified, said fluid being sent (4) towards the respective first chamber (6) of the membrane (5) whose respective second chamber (7) is filled with ink (1), whereby an inverse cycle to the previous one occurs, that is to say the second chamber (7) is emptied ) which is full, sending the ink (1) through the outlet (9), while the second chamber (7) of the other membrane (5) is filled with ink (1) that arrives through the entrance (8). Thus, by continuously repeating reverse cycles such as those mentioned, a continuous pumping of ink (1) is obtained, with a constant flow rate that can be regulated by varying the speed of rotation of the gears of the volumetric pump (3).
La alternancia de la direccion de envfo del fluido (4) que es impulsado por la bomba volumetrica (3), puede obtenerse, por ejemplo, alternando el sentido del accionamiento deThe alternation of the direction of envfo of the fluid (4) that is driven by the volumetric pump (3), can be obtained, for example, by alternating the direction of the drive of

giro de los engranajes (13) de dicha bomba volumetrica (3), mediante cualquier medio de control de la alternancia; o bien mediante un medio controlado de apertura y cierre de compuertas que permita hacer llegar el lfquido (4) hacia donde sea necesario en cada ciclo del sistema de bombeo; soluciones estas que no son limitativas, pudiendo utilizarse igualmente cualquier otra solucion que permita obtener el mismo efecto de envfo alterno del fluido (4) para actuar el desplazamiento del embolo (10) en dos sentidos opuestos.rotation of the gears (13) of said volumetric pump (3), by any means of alternating control; or by means of a controlled means of opening and closing of gates that allow the liquid (4) to be reached where it is necessary in each cycle of the pumping system; These solutions are not limiting, and any other solution that allows the same effect of alternating fluid (4) to actuate the movement of the plunger (10) in two opposite directions can also be used.
Asimismo, el fluido (4) es desplazable de acuerdo a un circuito cerrado, tal y como se corresponde con el ejemplo de realizacion mostrado en las figuras. Es decir, el fluido (4) es desplazable solo entre la bomba volumetrica (3) y las primeras camaras (6). Alternativamente, el fluido (4) es desplazable de acuerdo a un circuito abierto, es decir el fluido (4) esta tambien en comunicacion con un deposito adicional (no mostrado en las figuras) para un aporte adicional del fluido (4) requerido para mantener el caudal deseado de tinta (1) inyectada. De esta forma, se posibilita contrarrestar posibles fugas del fluido (4).Also, the fluid (4) is displaceable according to a closed circuit, as corresponds to the embodiment shown in the figures. That is, the fluid (4) is movable only between the volumetric pump (3) and the first chambers (6). Alternatively, the fluid (4) is movable according to an open circuit, that is the fluid (4) is also in communication with an additional tank (not shown in the figures) for an additional supply of the fluid (4) required to maintain the desired flow of ink (1) injected. In this way, it is possible to counteract possible leaks of the fluid (4).
El sistema de bombeo objeto de la invencion puede emplearse para bombear la tinta (1) a medios de impresion de las maquinas impresoras, tales como unos rodillos de impresion, y para aspirar o recuperar la tinta (1) bombeada a dichos medios de impresion que resulta excedente o sobrante, evitandose de esta manera que las maquinas de impresion resulten ensuciadas. De acuerdo con esto, una maquina impresora preferentemente comprende un sistema de bombeo para el bombeo de la tinta (1) a los medios de impresion o para la aspiracion de la tinta (1) sobrante bombeada a los medios de impresion, y mas preferentemente comprende dos sistemas de bombeo, uno para el bombeo de la tinta (1) a los medios de impresion y otro para la aspiracion de la tinta (1) sobrante bombeada a los medios de impresion.The pumping system object of the invention can be used to pump the ink (1) to printing means of the printing machines, such as printing rollers, and to aspirate or recover the ink (1) pumped to said printing means that It is surplus or surplus, thus preventing printing machines from getting dirty. Accordingly, a printing machine preferably comprises a pumping system for pumping the ink (1) to the printing means or for suctioning the remaining ink (1) pumped to the printing means, and more preferably comprising two pumping systems, one for the pumping of the ink (1) to the printing means and the other for the aspiration of the ink (1) left over to the printing means.
