Abstract

It is well known how important it is to maintain sterility on the valve body, and on metered delivery devices in particular, in the cases of valves designed for the metered delivery of e.g. pharmaceutical products. It is for this reason that the valves are subjected to frequent dismantling so that they can be cleaned. Clearly, for economic purposes, these operations of disassembly and subsequent reassembly must be performed as quickly as possible and by one operator. The present invention solves the problem by providing a system for fastening the various members in question by means of magnetic couplings obtained by the insertion of permanent magnets in the vicinity of the contact surfaces. <IMAGE>

Description

Dispositivo de dispensación dosificada con acoplamiento magnético.Dispensing device dosed with magnetic coupling

La presente invención se refiere a la introducción de acoplamientos magnéticos en el interior de válvulas para la dispensación dosificada de productos para usos farmacéuticos, alimenticios o similares, que permitan un desmontaje rápido, y un subsiguiente reensamblaje rápido, de los dispositivos de dispensación en dosis situados en el interior de las válvulas, siendo tales operaciones muy frecuentes para permitir el mantenimiento de las condiciones indispensables de esterilidad en el tratamiento de productos.The present invention relates to the introduction of magnetic couplings inside valves for the dosed dispensing of products for uses Pharmaceutical, food or similar, allowing disassembly fast, and subsequent quick reassembly, of the devices of dispensing in doses located inside the valves, such operations being very frequent to allow the maintenance of the essential sterility conditions in the product treatment.

La técnica anterior ya incluye válvulas de dispensación dosificadas, algunas de las cuales presentan un sistema dual de dispensación dosificada en el cual el primer sistema de dispensación es de aproximación y toma la forma de, por ejemplo, una válvula de mariposa que ocupa por completo la abertura del cuerpo de válvula, mientras que el segundo sistema, el cual se encuentra formado en el interior del cuerpo del primer sistema, presenta dimensiones menores y está construido de formas diversas, siendo su control independiente del sistema de aproximación.The prior art already includes valves dosed dispensing, some of which have a system dual dispensing dispensed in which the first system of dispensing is approximation and takes the form of, for example, a butterfly valve that completely occupies the opening of the body of valve, while the second system, which is located formed inside the body of the first system, presents smaller dimensions and is constructed in different ways, being its independent control of the approach system.

No resulta relevante el tratar aquí los diferentes tipos de elementos de serie existentes, puesto que ello no forma parte del objeto de la invención. Por lo tanto, la explicación sobre la invención se limitará al caso de una válvula en la que la condición de cierre se obtiene mediante sistemas de válvula de mariposa individuales y dobles, puesto que las consideraciones expuestas en estos casos pueden aplicarse asimismo a cualquier otra situación.It is not relevant to try here the different types of existing series elements, since It is not part of the object of the invention. Therefore, the explanation about the invention will be limited to the case of a valve in which the closing condition is obtained by means of single and double butterfly valves, since considerations set forth in these cases may also apply to Any other situation.

En las válvulas de dispensación dosificada existentes, en el proceso de montaje de las válvulas, incluso para las de tipo rápido, siempre se requieren tornillos, clavijas, etcétera, y como consecuencia en las operaciones de desmontaje y de reensamblaje siempre se requiere la presencia de dos personas, debido al peso del elemento de cierre y a la dificultad que conlleva el acercar y centrar de forma satisfactoria las dos bridas.In dosed dispensing valves existing, in the process of mounting the valves, even for the fast type, screws, pegs are always required, etcetera, and as a consequence in the disassembly and reassembly always requires the presence of two people, due to the weight of the closure element and the difficulty involved the approach and center of the two flanges satisfactorily.

El objetivo de la presente invención consiste en hacer posible que las operaciones mencionadas las lleve a cabo una sola persona.The objective of the present invention is to make it possible for the aforementioned operations to be carried out by single person

Para lograr este objetivo se ha concebido un sistema para unir los diferentes elementos en cuestión por medio de acoplamientos magnéticos que se obtienen mediante la inserción de imanes permanentes cerca de las superficies de contacto de manera que se crea una atracción entre las dos partes que es suficiente para soportar el peso de las secciones de ejes coincidentes.To achieve this goal, a system to join the different elements in question through magnetic couplings that are obtained by inserting permanent magnets near the contact surfaces so that an attraction is created between the two parties that is sufficient to support the weight of the matching axis sections.

La invención tal como se caracteriza en las reivindicaciones solventa el problema de hacer posible que una persona junte las dos superficies y las una gracias a la simple fuerza de atracción ejercida por los imanes permanentes.The invention as characterized in the claims solve the problem of making it possible for a person join the two surfaces and one thanks to the simple force of attraction exerted by permanent magnets.

La invención se describe con mayor detalle a continuación con la ayuda de los dibujos que ilustran un ejemplo de una forma de realización de la misma.The invention is described in greater detail in then with the help of the drawings that illustrate an example of an embodiment thereof.

Con referencia a la lámina nº 1, la figura 1 muestra la sección transversal longitudinal a través de un eje (1) que en su extremo acomoda un imán fijo (m) insertado en una ranura circular anular cuyo eje magnético coincide con el eje geométrico del eje, tal como se muestra en la figura 2.With reference to sheet No. 1, Figure 1 shows the longitudinal cross section through an axis (1) that at its end accommodates a fixed magnet (m) inserted in a slot annular circular whose magnetic axis coincides with the geometric axis of the shaft, as shown in figure 2.

El método mediante el cual se fija el imán a la ranura circular anular depende del tipo de material del eje: si se trata de material ferromagnético, queda fijado por la atracción ejercida por cada uno de los imanes permanentes, mientras que si se trata de material diamagnético, como por ejemplo aceros inoxidables o materiales plásticos, la ranura debe cerrarse, por ejemplo: con una arandela (v) soldada o bien atornillada a su alojamiento, o bien fijada con cualquier otro sistema.The method by which the magnet is fixed to the annular circular groove depends on the type of shaft material: if it is ferromagnetic material, it is fixed by the attraction exerted by each of the permanent magnets, while if it deals with diamagnetic material, such as stainless steels or plastic materials, the groove must be closed, for example: with a washer (v) welded or bolted to its housing, or set with any other system.

La figura 3 muestra unos tramos de los ejes (1) y (1') unidos magnéticamente: resulta evidente que las polaridades de los imanes permanentes opuestos deben ser de signo contrario.Figure 3 shows sections of the axes (1) and (1 ') magnetically linked: it is clear that the polarities of opposite permanent magnets must be of opposite sign.

La figura 4 se muestra la aplicación de la invención a un eje con una brida (2).Figure 4 shows the application of the invention to a shaft with a flange (2).

La lámina nº 2 muestra la aplicación de los principios mencionados anteriormente en una válvula que se utiliza para dispensar cantidades dosificadas de productos en gránulos, en polvo o similares que se emplean en la industria farmacéutica o alimentaria, y que consiste en un cuerpo cilíndrico (3). La válvula es de las del tipo de doble válvula de mariposa, configurando ésta los elementos de cierre del producto, es decir que la válvula (4) ocupa completamente la sección transversal del cuerpo de válvula, y que la válvula (5) ocupa una porción central del elemento anterior y hace posible un control más preciso del producto.Sheet No. 2 shows the application of the principles mentioned above in a valve that is used for dispensing dosed quantities of products in granules, in powder or the like used in the pharmaceutical industry or food, and consisting of a cylindrical body (3). The valve It is the type of double butterfly valve, configuring it the closing elements of the product, that is to say the valve (4) completely occupies the cross section of the valve body, and that the valve (5) occupies a central portion of the anterior element and makes possible a more precise control of the product.

Tal como se ha expuesto anteriormente, las consideraciones aplicadas a este tipo de válvula, siempre y cuando se refieran a la presente patente, pueden aplicarse a válvulas con elementos de cierre individuales o duales de cualquier otro tipo, tal como se apreciará a continuación a partir de una lectura cuidadosa del resto de la descripción.As stated above, the considerations applied to this type of valve, as long as refer to the present patent, can be applied to valves with individual or dual closure elements of any other type, as will be seen below from a reading careful of the rest of the description.

La figura 5 de la página 2 muestra el eje de control (6) del elemento de cierre (4), y el eje de control (7) del elemento de cierre (5), estando estos ejes realizados en segmentos unidos entre sí mediante el acoplamiento magnético descrito anteriormente, y los dos anillos (8) y (9) conectan la válvula al resto del sistema, que está también realizado de forma integral con el cuerpo (3) de la válvula mediante acoplamiento magnético.Figure 5 on page 2 shows the axis of control (6) of the closing element (4), and the control axis (7) of the closing element (5), these axes being made in segments linked together by the magnetic coupling described above, and the two rings (8) and (9) connect the valve to the rest of the system, which is also done integrally with the body (3) of the valve by magnetic coupling.

Las figuras muestran los imanes permanentes (m1) que, gracias a su atracción magnética, proporcionan continuidad al eje que forma parte del elemento de cierre completo, los imanes permanentes (m2) que forman parte del elemento de cierre (5), y los imanes permanentes (m3) y (m4) que forman parte de los anillos (8) y (9), respectivamente. La figura 6 muestra la válvula en vista superior.The figures show the permanent magnets (m1) which, thanks to its magnetic attraction, provide continuity to the shaft that is part of the complete closure element, the magnets permanent (m2) that are part of the closing element (5), and the permanent magnets (m3) and (m4) that are part of the rings (8) and (9), respectively. Figure 6 shows the valve in view higher.

La figura 7 de la página 3 muestra la sección longitudinal a través de la válvula en un plano perpendicular al de la sección representada en la figura 5 en la lámina 2 que ilustra los mismos componentes y con los dos anillos adaptadores (8) y (9) separados del cuerpo (3) de la válvula. La figura 8 muestra la válvula en vista superior.Figure 7 on page 3 shows the section longitudinally through the valve in a plane perpendicular to that of the section depicted in figure 5 on sheet 2 illustrating the same components and with the two adapter rings (8) and (9) separated from the body (3) of the valve. Figure 8 shows the top view valve.

La lámina 4 muestra una forma de realización posible de la invención en un caso en el cual el cuerpo de válvula (3) consiste en dos semicuerpos que se pueden separar (3') y (3''), y asimismo en aras de la simplicidad del dibujo se muestra un elemento de cierre individual; si bien las conclusiones a las que se ha llegado pueden aplicarse también en el caso de un elemento de cierre dual. En este caso, la interrupción del eje puede situarse en el exterior del cuerpo de válvula o bien en el interior, tal como ocurre en el caso descrito anteriormente, que presenta ejes con bridas en los extremos o sin ellas.Sheet 4 shows an embodiment possible of the invention in a case in which the valve body (3) consists of two half-bodies that can be separated (3 ') and (3' '), and also for the sake of simplicity of the drawing a individual closing element; although the conclusions to which has arrived can also be applied in the case of an element of dual closure In this case, the axis interruption can be placed at the outside of the valve body or inside, such as occurs in the case described above, which has axes with flanges on the ends or without them.

La lámina 4 indica una forma de realización posible de este tipo de válvula con un eje con una brida en el extremo. Las figuras 9 y 10 muestran dos secciones longitudinales perpendiculares entre sí a través de la válvula mostrando el eje (6) con bridas (10) en los que se encuentran situados los imanes permanentes (m5) para efectuar el acoplamiento. La figura 11 muestra una vista en planta del semicuerpo (3') de la válvula, en el que, puede observarse el electroimán (6) situado en la ranura anular circular del semicuerpo de válvula (3'); ahora por supuesto esta ranura se halla interrumpida en los casquillos (11). Todas las otras indicaciones se refieren a piezas que ya se han descrito anteriormente, incluyendo los imanes permanentes (m3) y (m4) para efectuar el acoplamiento con los anillos adaptadores (8) y (9) (no representados). En este caso, la interrupción del eje (6) puede situarse en el exterior del cuerpo de válvula (3) para permitir el desmontaje de los elementos de cierre una vez que los dos semicuerpos (3') y (3'') se han separado.Sheet 4 indicates an embodiment possible of this type of valve with a shaft with a flange on the extreme. Figures 9 and 10 show two longitudinal sections perpendicular to each other through the valve showing the shaft (6) with flanges (10) in which the magnets are located permanent (m5) to do the coupling. Figure 11 shows a plan view of the half body (3 ') of the valve, in which, the electromagnet (6) located in the annular groove can be observed circular valve half body (3 '); now of course this slot is interrupted in the bushings (11). All the others indications refer to parts that have already been described previously, including permanent magnets (m3) and (m4) for make the coupling with the adapter rings (8) and (9) (no represented). In this case, the interruption of the shaft (6) can be located outside the valve body (3) to allow disassembly of the closure elements once both half bodies (3 ') and (3' ') have separated.

A la vista de lo expuesto anteriormente resultará obvio que el montaje de las dos partes del elemento de cierre de la válvula y de la válvula en sí misma en el sistema puede llevarlo a cabo una sola persona, la cual simplemente tiene que colocar juntos los dos elementos en cuestión. Lo mismo puede exponerse en relación con las operaciones de desmontaje para las cuales solamente se requiere separar las caras coincidentes de las piezas en cuestión.In view of the above, it will be obvious that the assembly of the two parts of the closure element of the valve and the valve itself in the system can take you to one person out, which you simply have to place together The two elements in question. The same can be stated in relation with disassembly operations for which only requires separating the matching faces of the pieces in question.
