DESCRIPCIÓN DESCRIPTION
Sistema destinado a compactar polvos cerámicos para formar losas utilizando una cinta. System designed to compact ceramic powders to form slabs using a tape.
5 La presente invención se refiere a un sistema para compactar polvos cerámicos para formar losas utilizando una cinta. The present invention relates to a system for compacting ceramic powders to form slabs using a tape.
Como es conocido, el proceso de formación en seco de polvos cerámicos en una cinta prevé el uso de cintas de compactación, inferior y superior, respectivamente, que cooperan para compactar en seco una banda de polvos 10 cerámicos que se hace avanzar, a través de una cinta transportadora dispuesta entre ellas, en un sentido de avance paralelo a la cinta inferior. As is known, the dry-forming process of ceramic powders on a belt provides for the use of compaction belts, lower and upper, respectively, which cooperate to dry compact a band of ceramic powders that are advanced, through a conveyor belt arranged between them, in a direction of advance parallel to the lower belt.
La compactación es ayudada por dos rodillos de compactación que se mantienen presionados contra la banda de polvos cerámicos. The compaction is aided by two compaction rollers that remain pressed against the band of ceramic powders.
15 La cinta superior tiene una primera parte de recepción inclinada con respecto a la dirección en la que avanzan los polvos y una segunda parte de expansión, respectivamente, aguas arriba y aguas abajo de los rodillos de compactación presentes en la zona de compactación. The upper belt has a first reception part inclined with respect to the direction in which the powders advance and a second expansion part, respectively, upstream and downstream of the compaction rollers present in the compaction zone.
20 La inclinación de la primera parte de la cinta superior, con respecto al sentido de avance de la banda de polvos, asegura un aplastamiento progresivo de los polvos y permite que el aire presente dentro de ellos sea expulsado. The inclination of the first part of the upper belt, with respect to the direction of advance of the dust band, ensures a progressive crushing of the powders and allows the air present within them to be expelled.
Un sistema de compactación de esta índole se describe con detalle en la solicitud de patente europea EP-A1356909 del mismo solicitante, a la que nos referimos para una comprensión completa de él. El documento EP 25 1226927-A2 da a conocer un sistema para compactar polvos cerámicos de acuerdo con el preámbulo de la reivindicación 1. Such a compaction system is described in detail in the European patent application EP-A1356909 of the same applicant, which we refer to for a complete understanding of it. EP 25 1226927-A2 discloses a system for compacting ceramic powders according to the preamble of claim 1.
Hasta ahora se ha considerado que dicha inclinación debe estar comprendida entre 1º y 2º. Until now it has been considered that this inclination must be between 1º and 2º.
30 Sin embargo, a medida que aumenta el espesor de polvo que se ha de prensar, se ha encontrado que existe una descarga insuficiente de aire durante el prensado. 30 However, as the thickness of the powder to be pressed increases, it has been found that there is insufficient air discharge during pressing.
La ausencia de aire en el artículo formado es necesaria para evitar imperfecciones durante los desplazamientos, decoración y cocción posteriores. The absence of air in the formed article is necessary to avoid imperfections during subsequent movements, decoration and cooking.
35 Si el aire está presente los artículos tienden a romper, dividiéndose en capas delgadas, en detrimento de la integridad requerida del producto final. 35 If air is present the articles tend to break, dividing into thin layers, to the detriment of the required integrity of the final product.
El fenómeno es más notable cuando se procesan bandas de polvos cerámicos de un espesor mayor de 30 mm. The phenomenon is most noticeable when processing ceramic dust bands of a thickness greater than 30 mm.
40 Otro inconveniente de los sistemas conocidos se deriva del hecho de que la parte de recepción de la cinta superior, debido a la inclinación bastante pequeña, de menos de 2º, implica un alargamiento de la parte de recepción del polvo que es cada vez mayor cuanto mayor es el espesor del polvo. 40 Another drawback of the known systems derives from the fact that the receiving part of the upper belt, due to the rather small inclination, of less than 2 °, implies an elongation of the receiving part of the dust which is increasing as long as The greater the thickness of the powder.
45 Por lo tanto, la compactación continua tiene un uso limitado a pequeños espesores de polvo con bajos grados de compactación (reducción en el espesor no mayor de 30%). 45 Therefore, continuous compaction has limited use at small dust thicknesses with low degrees of compaction (thickness reduction not greater than 30%).
El objetivo de la presente invención es proporcionar un sistema para compactar polvos cerámicos a fin de formar losas utilizando una cinta que asegure la completa expulsión del aire, durante la compactación, también para 50 espesores de polvos y grados de compactación elevados. The aim of the present invention is to provide a system for compacting ceramic powders to form slabs using a tape that ensures complete expulsion of air, during compaction, also for 50 powder thicknesses and high degrees of compaction.
Un objetivo adicional es proporcionar un sistema que tenga un tamaño, volumen y costes limitados en comparación con los de la técnica anterior. An additional objective is to provide a system that has a limited size, volume and costs compared to those of the prior art.
55 Dichos objetivos se alcanzan mediante un sistema para compactar polvos cerámicos para formar losas utilizando una cinta según la reivindicación 1. Said objectives are achieved by a system for compacting ceramic powders to form slabs using a tape according to claim 1.
Las reivindicaciones dependientes describen formas de realización preferidas y particularmente ventajosas del sistema de acuerdo con la invención. The dependent claims describe preferred and particularly advantageous embodiments of the system according to the invention.
60 Otras características y ventajas de la invención se pondrán de manifiesto a partir de una lectura de la siguiente descripción proporcionada a título de ejemplo y no limitativo, con la ayuda de la figura ilustrada en la hoja adjunta, que muestra una vista esquemática de un sistema para la compactación de polvos cerámicos para formación de losas utilizando una cinta de acuerdo con la presente invención.

Haciendo referencia a la figura mencionada anteriormente, un sistema destinado a compactar polvos cerámicos para formar losas utilizando una cinta de acuerdo con la presente invención se indica globalmente con 1. Referring to the aforementioned figure, a system intended to compact ceramic powders to form slabs using a tape according to the present invention is indicated globally with 1.
El sistema 1 comprende una cinta transportadora 40 sobre la que se crea una banda continua "S" de material cerámico en polvo, una primera cinta de compactación inferior 20 dispuesta en contacto con la cinta transportadora 40 y una segunda cinta de compactación superior 30 que coopera con la primera cinta 20 para compactar en seco la banda S de polvos y obtener un artículo coherente de polvos compactados. The system 1 comprises a conveyor belt 40 on which a continuous band "S" of ceramic powder material is created, a first lower compaction belt 20 arranged in contact with the conveyor belt 40 and a second upper compaction belt 30 cooperating with the first tape 20 for dry compacting the powder band S and obtaining a coherent article of compacted powders.
La cinta superior 30 tiene una primera parte de alojamiento 30a, dispuesta a la izquierda en la figura, y una segunda parte de expansión 30b, dispuesta a la derecha en la figura. The upper belt 30 has a first housing part 30a, arranged on the left in the figure, and a second expansion part 30b, arranged on the right in the figure.
Se efectúa la contención lateral de los polvos, como de costumbre, por dos paredes laterales deformables proporcionadas por las cintas 60. Lateral containment of the powders is carried out, as usual, by two deformable side walls provided by the tapes 60.
De acuerdo con la presente invención, se ha visto que, con el fin de expulsar efectivamente el aire incorporado en la banda S de polvos, es esencial que la longitud "A" de la parte de la banda S de polvos involucrada en el instante de compactación sea lo más corta como sea posible. In accordance with the present invention, it has been seen that, in order to effectively expel the air incorporated in the dust band S, it is essential that the length "A" of the part of the dust band S involved at the time of compaction be as short as possible.
Según la invención, la parte de recepción 30a de la cinta superior 30 tiene una inclinación "β" con respecto al sentido en el que avanzan los polvos de entre 2º y 14º, preferentemente de entre 3º y 10º. According to the invention, the receiving part 30a of the upper belt 30 has an inclination "β" with respect to the direction in which the powders of between 2 ° and 14 ° advance, preferably between 3 ° and 10 °.
En el ejemplo, cada cinta 20, 30 está enrollada en un par de rodillos, uno de los cuales es un rodillo de accionamiento, respectivamente indicado con 32 para la cinta superior 30 y con 22 para la cinta inferior 20, y el otro de las cuales es un rodillo loco, indicados respectivamente con 31 para la cinta superior 30 y con 21 para la cinta inferior 20. In the example, each belt 20, 30 is wound in a pair of rollers, one of which is a drive roller, respectively indicated with 32 for the upper belt 30 and with 22 for the lower belt 20, and the other of the which is a crazy roller, indicated respectively with 31 for the upper belt 30 and with 21 for the lower belt 20.
Los rodillos 31, 32 y 21, 22 de cada par están dispuestos a una distancia aparte tal como para mantener tensas las respectivas cintas enrolladas 30, 20. The rollers 31, 32 and 21, 22 of each pair are arranged at a separate distance such as to keep the respective coiled tapes 30, 20 tense.
Con el fin de llevar a cabo la acción de compactación de manera más efectiva, la cinta inferior 20 y la cinta superior 30 están equipadas con un rodillo de compactación, indicado con 33 para la cinta superior 30 y con 23 para la cinta inferior 20. In order to carry out the compaction action more effectively, the lower belt 20 and the upper belt 30 are equipped with a compaction roller, indicated with 33 for the upper belt 30 and 23 for the lower belt 20.
Los dos rodillos de compactación 33 y 23 actúan directamente sobre las cintas 30, 20 en los puntos de tangencia, indicados con 34 y 24, respectivamente, para la cinta superior 30 y para la cinta inferior 20. The two compaction rollers 33 and 23 act directly on the belts 30, 20 at the tangency points, indicated 34 and 24, respectively, for the upper belt 30 and the lower belt 20.
Básicamente, la distancia entre los dos puntos de tangencia 34 y 24 es igual, los espesores de las cintas aparte, a la separación mínima a través de la que la banda S de polvos es forzada a pasar. Basically, the distance between the two tangency points 34 and 24 is equal, the thicknesses of the belts apart, to the minimum separation through which the dust band S is forced to pass.
Además, y como se conoce en el campo, entre los pares de rodillos 31, 32 y 21, 22 están dispuestos dos rodillos 36, 26, formados a partir de una pluralidad de rodillos locos, que actúan sobre las respectivas cintas 30, 20 aguas arriba de los dos rodillos de compactación 33, 23 y que tienen la función de mantener las cintas 30 y 20 presionadas para presionar la banda de polvos S. In addition, and as is known in the field, between the pairs of rollers 31, 32 and 21, 22 there are two rollers 36, 26, formed from a plurality of crazy rollers, which act on the respective ribbons 30, 20 waters above the two compaction rollers 33, 23 and which have the function of keeping the belts 30 and 20 pressed to press the powder band S.
Con el fin de obtener una compactación correcta, los ejes respectivos de los rodillos de compactación 33, 23 se encuentran en un plano común perpendicular a la dirección en la que avanza la banda S de polvos. In order to obtain a correct compaction, the respective axes of the compaction rollers 33, 23 are in a common plane perpendicular to the direction in which the dust band S advances.
Para variar el espesor deseado de la losa final debe variarse la distancia mínima entre las dos cintas 30, 20 y por lo tanto la distancia entre los dos rodillos de compactación 33 y 23, es decir, la posición mutua entre los puntos de tangencia 34 y 24. To vary the desired thickness of the final slab, the minimum distance between the two belts 30, 20 and therefore the distance between the two compaction rollers 33 and 23 must be varied, that is, the mutual position between the tangency points 34 and 24.
Esto puede llevarse a cabo a través de medios desplazadores, conocidos en el campo y que por lo tanto no se ilustran en la presente memoria, aptos para separar y acercar los rodillos de compactación 33, 23 perpendicularmente con respecto a la dirección en la que avanzan los polvos. This can be carried out through displacer means, known in the field and therefore not illustrated herein, suitable for separating and bringing the compaction rollers 33, 23 perpendicularly with respect to the direction in which they are moving. the powders
Por supuesto, se aleja la cinta superior 30 de la cinta inferior 20 a través del desplazamiento de los rodillos 31, 32 sobre los que está enrollada. Of course, the upper belt 30 is moved away from the lower belt 20 through the displacement of the rollers 31, 32 on which it is wound.
Aguas abajo de los rodillos de compactación 33, 23 se encuentran dos placas opuestas, de modo que la primera 35 actúa sobre la parte de expansión 30b de la cinta superior 30 y la segunda actúa sobre la cinta inferior 20, para controlar la expansión espontánea de la banda de polvos compactados S. Downstream of the compacting rollers 33, 23 are two opposite plates, so that the first 35 acts on the expansion part 30b of the upper belt 30 and the second acts on the lower belt 20, to control the spontaneous expansion of the band of compacted powders S.
Convenientemente, a fin de permitir la compactación de bandas S de polvos que tienen espesores sustancialmente diferentes, así como separar adecuadamente las cintas 30, 20 y los respectivos rodillos de compactación 33, 23, la inclinación β de la primera parte de recepción 30a puede variarse también, según se desee entre 2º y 14º, preferentemente entre 3º y 10º con respecto a la dirección en la que avanza la banda S de polvos. Conveniently, in order to allow compaction of S bands of powders having substantially different thicknesses, as well as properly separating the tapes 30, 20 and the respective compacting rollers 33, 23, the inclination β of the first receiving part 30a can be varied also, as desired between 2 ° and 14 °, preferably between 3 ° and 10 ° with respect to the direction in which the S band of powders advances.

Esto es posible, por ejemplo, utilizando unos medios aptos, no ilustrados, que permiten que el rodillo dispuesto en el extremo de entrada de la banda S de polvos, en el ejemplo el rodillo loco 31, se aleje y se acerque con respecto a la cinta transportadora 40 en la que está dispuesta la banda S continua de polvos cerámicos. This is possible, for example, by using suitable means, not illustrated, which allow the roller disposed at the inlet end of the dust band S, in the example the idler roller 31, to move away and approach with respect to the conveyor belt 40 on which the continuous S band of ceramic powders is arranged.
5 A medida que la inclinación β asignada a la parte de recepción 30a varía, el punto de primer contacto, indicado con 50, entre la banda S de polvos y la propia parte de recepción 30a de la cinta superior 30 se acerca a los rodillos de compactación 33, 23, mientras se alejan a medida que el espesor de la banda S aumenta. 5 As the inclination β assigned to the receiving part 30a varies, the first contact point, indicated 50, between the dust band S and the receiving part 30a of the upper belt 30 itself approaches the rollers of compaction 33, 23, as they move away as the thickness of the S band increases.
10 La elección de la inclinación β más adecuada para ser asignada a la parte de recepción 30a para eliminar eficazmente el aire incorporado en los polvos que se han de compactar se lleva a cabo teniendo en cuenta las propiedades específicas de los polvos que se han de tratar. 10 The choice of the most suitable inclination β to be assigned to the receiving part 30a to effectively remove the air incorporated in the powders to be compacted is carried out taking into account the specific properties of the powders to be treated .
En particular, debe tenerse en cuenta su fluidez. De hecho, si la inclinación β fuera excesiva, la parte superior de la 15 banda S de polvos no sería llevada entre las cintas 20, 30 debido a lo que en el argot se denomina "residuos". In particular, its fluidity must be taken into account. In fact, if the inclination β was excessive, the upper part of the S band of powders would not be carried between the ribbons 20, 30 due to what in the slang is called "waste".
De las pruebas realizadas se ha averiguado que a fin de obtener una suficiente desaireación del polvo, la longitud A de la parte de la banda S de polvos implicada en el instante de la compactación debe ser de entre 2 y 28 veces el espesor de la banda S. From the tests carried out, it has been found that in order to obtain sufficient dust deaeration, the length A of the part of the dust band S involved at the time of compaction must be between 2 and 28 times the thickness of the band S.
20 Donde la longitud A es igual a la de la proyección, sobre la cinta transportadora 40, de la distancia entre el punto de primer contacto 50 de la cinta superior 30 por la banda S de polvos y el punto de tangencia 34 del rodillo de compactación 33 con la cinta superior 30. 20 Where the length A is equal to that of the projection, on the conveyor belt 40, of the distance between the first contact point 50 of the upper belt 30 by the dust band S and the tangency point 34 of the compaction roller 33 with the upper belt 30.
25 Como se puede apreciar a partir de lo que se ha descrito, el sistema para compactar polvos cerámicos para formar losas utilizando una cinta de acuerdo con la presente invención permite satisfacer los requisitos y permite superar los inconvenientes mencionados en la parte introductoria de la presente descripción con referencia a la técnica anterior.
