El presente invento se refiere a un aparato mejorado para producir tejas u otros artículos a partir de mezclas de cemento.The present invention relates to an apparatus Improved to produce tiles or other items from mixtures of cement.
Desde hace tiempo son conocidos aparatos para preparar y conformar mezclas de cemento para formar tejas y otros artículos de diferentes formas y grosores, y que han sido el sujeto de muchísimas patentes, tales como la Patente Francesa 2117398, las Patentes Italianas 1023789 y 1786883, y la Solicitud de Patente Europea EP-A-0893219.Devices have long been known for prepare and form cement mixtures to form shingles and others articles of different shapes and thicknesses, and that have been the subject of many patents, such as French Patent 2117398, the Italian Patents 1023789 and 1786883, and the Patent Application European EP-A-0893219.
El aparato conocido comprende un molde para recibir una masa dosificada de mezcla de cemento y un macho de estampa para comprimir esa mezcla dentro del molde. A su vez, el molde comprende un bastidor rígido y una rejilla que presenta gran número de agujeros, de diámetros que van aumentando gradualmente hacia abajo y que comunican con canales de drenaje para el líquido que pase a través de dichos agujeros cuando se forme cada teja. El bastidor rígido descansa sobre dicha rejilla y define con ella una cavidad (abierta hacia arriba) dentro de la cual se alimentan cantidades dosificadas de mezcla de cemento para formar tejas individuales.The known apparatus comprises a mold for receive a dosed mass of cement mix and a male of stamp to compress that mixture inside the mold. In turn, the mold comprises a rigid frame and a grid that presents great number of holes, of diameters that are gradually increasing down and that communicate with drainage channels for the liquid to pass through these holes when each tile is formed. He rigid frame rests on said grid and defines with it a cavity (open upwards) into which they feed dosed amounts of cement mix to form shingles individual.
Directamente encima del molde está situado un macho de estampa que puede ser hecho funcionar mediante una prensa, y movible entre una posición en la cual está elevado, separado de dicho bastidor rígido y, respectivamente, una posición en la cual el extremo libre del macho de estampa penetra en la abertura en el bastidor rígido para comprimir la mezcla de cemento que está presente en ella.Directly above the mold is located a stamping male that can be operated by a press, and movable between a position in which it is elevated, separated from said rigid frame and, respectively, a position in which the free end of the stamper penetrates the opening in the rigid frame to compress the cement mixture that is present in it.
Durante la compresión de la mezcla de cemento se drena una gran parte del líquido contenido en la misma, a través de los agujeros de la rejilla del molde, aunque una parte del líquido escapa a presión entre las superficies opuestas del bastidor del molde y del macho de estampa de prensar.During the compression of the cement mixture, drains a large part of the liquid contained therein, through the holes of the grid of the mold, although a part of the liquid it escapes under pressure between the opposite surfaces of the frame of the Mold and stamping press.
Como ese líquido que rezuma entre el molde y el macho de estampa contiene cemento y gránulos de polvo de material inerte, para mantener el aparato en perfectas condiciones de funcionamiento se limpian frecuentemente el molde y el macho de estampa, y se procura eliminar el líquido, proporcionando para ello en los machos de estampa una pluralidad de agujeros que tienen un extremo que se abre en la superficie exterior de aquella parte del macho de estampa que penetra en el molde en el momento de comprimir la mezcla de cemento. El otro extremo de esos agujeros está conectado a una fuente de aspiración (véase la Solicitud de Patente Europea EP-A-0893219), la cual debería eliminar las consecuencias negativas del rezume de líquido desde el molde. El aire que es aspirado a través de esos agujeros al tener lugar la compresión de la mezcla de cemento, no impide, sin embargo, que escape el líquido al exterior entre las superficies del macho de estampa y del molde.Like that liquid that oozes between the mold and the Stamping male contains cement and material powder granules inert, to keep the device in perfect condition operation the mold and the male are frequently cleaned stamp, and attempts to remove the liquid, providing for it in the stamping males a plurality of holes that have a end that opens on the outer surface of that part of the stamping male that penetrates the mold at the time of compressing The cement mix. The other end of those holes is connected to a suction source (see Patent Application European EP-A-0893219), which should eliminate the negative consequences of liquid oozing from the mold. The air that is sucked through those holes upon compression of the cement mixture, it does not prevent, without However, let the liquid escape between the surfaces of the stamping male and the mold.
Además, el aire aspirado a través de los agujeros previstos en el macho de estampa descritos en la solicitud de patente antes mencionada, haría que el aparato llegase muy rápidamente a ser ineficaz, debido a que las partículas sólidas presentes en el líquido que rezuma a su través bloquearían los agujeros previstos en el macho de estampa.In addition, the air sucked through the holes provided in the stamping male described in the application of the aforementioned patent, would make the device arrive very quickly to be ineffective, because solid particles present in the liquid that oozes through would block the holes provided in the stamping male.
El objeto principal del presente invento es, por lo tanto, proporcionar un aparato adecuado para producir tejas a partir de mezclas de cemento, en el cual el líquido que rezume entre el molde y el macho de estampa durante la compresión de las mezclas es retirado y eliminado del aparato de un modo efectivo.The main object of the present invention is, by therefore, provide a suitable apparatus for producing tiles to from cement mixtures, in which the liquid that oozes between the mold and the stamper during compression of the mixtures It is removed and removed from the device in an effective way.

Con objeto de que se pueda llegar a una mejor comprensión de la estructura y de las características del aparato de acuerdo con el invento, se describe aquí en lo que sigue una realización del mismo, a modo de ejemplo no limitador, con referencia a los dibujos que se acompañan, en los cuales:In order to achieve a better understanding of the structure and characteristics of the device according to the invention, it is described here in what follows a realization thereof, by way of non-limiting example, with reference to the accompanying drawings, in which:
La Figura 1 es un corte longitudinal vertical esquemático a través del aparato, con el macho de estampa elevado por encima del molde; yFigure 1 is a vertical longitudinal section schematic through the device, with the raised stamp male above the mold; Y
La Figura 2 es similar a la Figura 1, pero con el macho de estampa en la posición de bajado sobre el molde.Figure 2 is similar to Figure 1, but with the stamping male in the lowered position on the mold.
El aparato para producir tejas, representado en las figuras, comprende un molde y un macho de estampa de prensar, que están superpuestos y son movibles cada uno con relación al otro.The apparatus for producing tiles, represented in the figures, comprises a mold and a press stamp male, that are superimposed and are movable each in relation to other.
El molde comprende a su vez una placa de base rígida 1, en la cual se han previsto una pluralidad de canales de drenaje 2 que tienen sus fondos inclinados, para hacer que los líquidos recogidos en ellos fluyan hacia tuberías de descarga 3. Sobre la placa 1 descansa una rejilla de base 4 formada por una o más placas que presentan una pluralidad de agujeros (representados solamente en el lado izquierdo de las figuras, en corte), sobre la cual descansa una malla o tela 5.The mold in turn comprises a base plate rigid 1, in which a plurality of channels of drain 2 that have their sloping bottoms, to make the liquids collected in them flow into discharge pipes 3. On the plate 1 rests a base grid 4 formed by one or more plates presenting a plurality of holes (represented only on the left side of the figures, in section), on the which rests a mesh or cloth 5.
Sobre dicha malla hay un bastidor rígido 6 que descansa sobre, y obtura contra, una junta anular 7. El bastidor 6 está recorrido por una abertura que está limitada por la parte inferior por la rejilla perforada 4 y la malla 5, para formar con ellas una cavidad dispuesta para alojar y retener a una masa de mezcla de cemento 8, del tipo usado para formar tejas.On said mesh there is a rigid frame 6 that rests on, and seals against, an annular seal 7. The frame 6 it is covered by an opening that is limited by the part bottom by perforated grid 4 and mesh 5, to form with they a cavity arranged to house and retain a mass of cement mix 8, of the type used to form tiles.
Por encima de la abertura del bastidor 6 hay un macho de estampa de prensar 9 conectado a un émbolo movible 10 de una prensa. La forma y el tamaño de la parte inferior (con referencia al dibujo) del macho de estampa 9, son tales que el mismo puede penetrar (con la menor holgura posible) dentro de la cavidad del bastidor 6, para comprimir la masa de mezcla de cemento 8, como se ha ilustrado en la Figura 2.Above the opening of the frame 6 there is a press stamp male 9 connected to a movable piston 10 of a press The shape and size of the bottom (with reference to the drawing) of the stamping male 9, are such that the it can penetrate (with as little slack as possible) into the frame cavity 6, to compress the cement mix mass 8, as illustrated in Figure 2.
La estructura y el funcionamiento del aparato antes descrito pueden ser de tipo conocido, por ejemplo, tal como se han representado en las Patentes anteriores citadas en la introducción a la descripción hecha en lo que antecede. Para simplificar, no se considerarán, por lo tanto, con mayor detalle.The structure and operation of the device described above may be of known type, for example, such as they have been represented in the previous patents cited in the Introduction to the description made above. For simplify, therefore, will not be considered with greater detail.
Se expresará, simplemente, que en la realización representada en los dibujos que se acompañan, en el macho de estampa 9 hay agujeros 11 que tienen un extremo que se abre en la superficie periférica inferior del macho de estampa, y su otro extremo conectable a una fuente de aire comprimido, con el fin de impedir que el agua rezume entre el macho de estampa y el bastidor del molde durante el prensado de la mezcla de cemento 8. Para facilitar la retirada del agua de drenaje que fluye al interior de los canales 2 de la placa 1, ese extremo de esos canales distante de aquel en el que se han previsto las tuberías de descarga 3, puede ser conectado, a través de agujeros 12, a una fuente de aire comprimido que facilite la retirada de cualesquiera depósitos de material sólido que puedan haberse recogido en los canales de drenaje 2.It will simply be expressed that in the realization represented in the accompanying drawings, in the male of stamp 9 there are holes 11 that have an end that opens in the lower peripheral surface of the stamping male, and its other end connectable to a source of compressed air, in order to prevent water from oozing between the stamper and the frame of the mold during pressing of the cement mixture 8. For facilitate the removal of drainage water flowing into the channels 2 of the plate 1, that end of those distant channels of the one in which the discharge pipes 3 are provided, can be connected, through holes 12, to an air source tablet that facilitates the withdrawal of any deposits of solid material that may have been collected in the channels of drain 2.
Con independencia del uso que se haga de cuanto ha sido expuesto en lo que antecede, se ha observado, sin embargo, que parte del líquido expulsado de la mezcla de cemento 8 rezuma entre el macho de estampa 9 y el bastidor 6, con serias consecuencias que son fácilmente comprensibles si se considera que ese líquido arrastra en el mismo partículas de cemento y partículas sólidas de diversos tipos, que son de carácter abrasivo y que tienden a formar incrustaciones duras, difíciles de eliminar, en el exterior del bastidor, y deterioran el aspecto exterior de la teja.Regardless of how much is used has been exposed above, it has been observed, however, that part of the liquid expelled from the cement mixture 8 oozes between the stamp male 9 and the frame 6, with serious consequences that are easily understandable if one considers that that liquid drags in the same cement particles and particles solids of various types, which are abrasive and that they tend to form hard, hard to remove inlays in the outer frame, and deteriorate the outer appearance of the roof tile.
El objeto principal del aparato del presente invento es precisamente eliminar el antes citado inconveniente.The main object of the present apparatus The invention is precisely to eliminate the aforementioned drawback.
Para este fin, como se ve en los dibujos, encima del bastidor 6 y rodeando totalmente al macho de estampa 9, se ha previsto un aro rígido 13 cuya superficie inferior está conformada de tal modo que el aro 13 define con la superficie superior del bastidor 6/cuando el aro descansa sobre el bastidor, como se ha ilustrado en la Figura 2) una cámara anular 14, abierta hacia la superficie lateral del macho de estampa 9 y conectada por medio de conductos 16 a una bomba de aspiración, o similar (no representada), la cual aspira fuera todo el líquido que pueda rezumar entre el macho de estampa y el bastidor del molde.For this purpose, as seen in the drawings, above of the frame 6 and completely surrounding the stamping male 9, it has provided with a rigid ring 13 whose lower surface is shaped such that the ring 13 defines with the upper surface of the frame 6 / when the ring rests on the frame, as has been illustrated in Figure 2) an annular chamber 14, open towards the side surface of the stamping male 9 and connected by means of conduits 16 to a suction pump, or the like (not shown), which sucks out all the liquid that can ooze between the Stamping male and mold frame.
Preferiblemente, como en el ejemplo ilustrado en los dibujos, se asegura el aro 13 al macho de estampa 9 mediante resortes 16, o similares, los cuales permiten que el aro se traslade axialmente con relación al macho de estampa.Preferably, as in the example illustrated in the drawings, the ring 13 is secured to the stamping male 9 by springs 16, or the like, which allow the ring to move axially in relation to the stamping male.
Cuando está en reposo (Figura 1), el aro 13 está situado de tal modo que entra en contacto con la superficie adyacente del bastidor 6 del molde, antes de que el macho de estampa empiece a comprimir la masa 6 de mezcla de cemento. Mientras continúa el macho de estampa su recorrido de descenso, el aro permanece presionando fuertemente contra el bastidor 6, para comprimir los resortes 16.When at rest (Figure 1), ring 13 is positioned in such a way that it comes into contact with the surface adjacent to the frame 6 of the mold, before the stamping male Start compressing the cement mixture dough 6. While the stamping male continues its downward path, the hoop remains strongly pressing against frame 6, to compress the springs 16.
La aspiración del aire a través de los conductos 15 y de la cámara 14 comienza tan pronto como empieza a penetrar el macho de estampa 9 en el molde, y cesa al terminar la operación de prensado, cuando se eleva el macho de estampa, sacándolo fuera del molde (Figura 1).The aspiration of air through the ducts 15 and from chamber 14 begins as soon as the stamp male 9 in the mold, and ceases when the operation of pressing, when the stamping male is raised, pulling it out of the mold (Figure 1).
Ventajosamente, el aro 13 está formado por dos o más aros o segmentos de aro conectados juntos de manera que se hace posible que los mismos sean separados fácil y rápidamente para permitir un acceso fácil a todos los conductos previstos en el aro, y simplificar por consiguiente al máximo la limpieza de los conductos para retirar cualesquiera depósitos o incrustaciones que se formen en ellos.Advantageously, the ring 13 is formed by two or more hoops or hoop segments connected together so that it is made they may be separated easily and quickly to allow easy access to all ducts provided in the hoop, and therefore simplify the cleaning of ducts to remove any deposits or deposits that be formed in them.
