Description
Dispositivo para cargar material en polvo.Device for loading powder material.
La presente invención se refiere a un dispositivo que sirve para depositar material en polvo sobre una cinta transportadora en movimiento.The present invention relates to a device used to deposit powdered material on a moving conveyor belt
Los dispositivos para cargar y depositar material cerámico en polvo sobre una cinta transportadora normalmente se usan en líneas para producción de baldosas o azulejos cerámicos, para alimentar material suelto a por lo menos una prensa. La deposición sobre una cinta transportadora del material suelto, que se compone de polvos cerámicos, se realiza en estratos contiguos separados por intervalos adecuados. Cada uno de los estratos de polvo sufre un ciclo de carga en al menos una prensa para ser compactado formando una baldosa o un azulejo. Los documentos EP-A-927.687 y WO-A-98/23424 publican dispositivos para realizar baldosas o azulejos; el documento WO-A-98/23424 publica las características del preámbulo de la reivindicación 1.The devices for loading and depositing ceramic powder material on a conveyor belt They are normally used on lines for tile production or ceramic tiles, to feed loose material to at least a press The deposition on a conveyor belt of Loose material, which is composed of ceramic powders, is made in contiguous strata separated by appropriate intervals. Each one of the dust strata undergo a charge cycle in at least one Press to be compacted forming a tile. The EP-A-927,687 and WO-A-98/23424 publish devices to make tiles; The document WO-A-98/23424 publishes the characteristics of the preamble of claim 1.
La técnica conocida abarca dispositivos que comprenden un contenedor de material cerámico en polvo que presenta una abertura que sirve para hacer caer el material en polvo, y que está provisto de medios para abrir y cerrar la misma abertura. Abriendo y cerrando la abertura se obtiene la caída del material en polvo sobre una cinta transportadora formando estratos contiguos y sucesivos, cada uno de los cuales define una baldosa o un azulejo, cuya estructura en esta etapa está en un estado no compacto. La cinta transportadora lleva los estratos de polvo a una prensa, la cual, junto con la cinta, efectúa una primera fase de prensado de baja intensidad con presiones de carga comprendidas aproximadamente entre 20 y 50 kg/cm^{2}. A esos niveles de presión el material en polvo se compacta lo suficiente como para permitir de alguna manera su manipulación. En particular, la baldosa o azulejo premoldeado es tomado por planos de rodillos impulsados para su conducción hasta dentro de un molde de una segunda prensa, donde se realiza la compactación final aplicando presiones de aproximadamente 600 kg/cm^{2}.The known technique encompasses devices that they comprise a container of ceramic powder that presents an opening that serves to drop the powder material, and that It is provided with means to open and close the same opening. Opening and closing the opening results in the fall of the material in dust on a conveyor belt forming contiguous strata and successive, each of which defines a tile or tile, whose structure at this stage is in a non-compact state. The Conveyor belt carries the dust strata to a press, the which, together with the tape, performs a first phase of pressing low intensity with load pressures approximately between 20 and 50 kg / cm2. At those pressure levels the material in powder is compacted enough to allow somehow its manipulation In particular, the pre-molded tile is taken by driven roller planes for driving up inside a mold of a second press, where the final compaction applying pressures of approximately 600 kg / cm2.
Los dispositivos que se acaban de describir presentan algunas desventajas. La cinta transportadora, si se la somete a cargas totales de presión, sufre deformaciones permanentes que perjudican su planaridad necesaria para tener una deposición homogénea del material en polvo. Una cinta deformada, por ende, no se puede volver a usar, con lo cual el ciclo de prensado tiene que ser dividido en dos etapas sucesivas, una etapa de premoldeado con bajos valores de presión, y una etapa final de compactación con altos valores de presión. La etapa final de prensado de la baldosa o azulejo no se puede realizar directamente sobre la cinta, lo cual obliga a quitar de la misma las baldosas o azulejos premoldeados. Este aspecto del proceso implica la presencia de al menos una prensa adicional para compactar las baldosas o azulejos y un sistema complementario de transporte constituido, por ejemplo, por un plano de rodillos impulsados para alejar las baldosas o azulejos de la cinta transportadora.The devices just described They have some disadvantages. The conveyor belt, if it is undergoes total pressure loads, undergoes permanent deformations that harm your planarity necessary to have a bowel movement homogeneous powder material. A warped tape, therefore, does not can be reused, so the pressing cycle has to be divided into two successive stages, a pre-molded stage with low pressure values, and a final stage of compaction with high pressure values The final stage of pressing the tile or tile cannot be made directly on the tape, which forces to remove from it the pre-molded tiles. This aspect of the process implies the presence of at least one additional press to compact the tiles and a system complementary transport constituted, for example, by a plane of driven rollers to remove the tiles from the conveyer belt.
Otro dispositivo conocido incluye un contenedor de material cerámico en polvo provisto de una abertura para permitir la caída del material en polvo e incluye medios para cerrar y abrir la abertura, cuyo funcionamiento es igual al del dispositivo descrito con anterioridad. Un transportador abierto toma el material en polvo para llevarlo a la prensa, el cual se ve sometido a una presión principal junto con el material en polvo a compactar y se recolecta sobre un bobinador situado después de la prensa. Por lo tanto, la cinta se ve sometida a las deformaciones permanentes ya descritas, que la convierten en inutilizable para los siguientes ciclos de prensado.Another known device includes a container ceramic powder material provided with an opening for allow the powder to fall and includes means to close and open the opening, whose operation is equal to that of device described above. An open conveyor takes the powder material to take to the press, which looks subjected to a main pressure together with the powder material to compact and collected on a tape drive located after the press. Therefore, the tape is subjected to deformations permanent already described, which make it unusable for following pressing cycles.
Los dispositivos del tipo que se acaba de describir presentan la desventaja de requerir un alto grado de deshechos por lo que se refiere a la cinta transportadora, que en efecto es un elemento desechable, y el problema de la eliminación de esta cinta.Devices of the type just finished describe have the disadvantage of requiring a high degree of undone as regards the conveyor belt, which in Effect is a disposable item, and the problem of disposal of this tape.
El objetivo principal de la presente invención es el de eliminar las desventajas descritas con anterioridad proporcionando un dispositivo para cargar material en polvo, que permita llevar a cabo un ciclo de prensado a alta presión sobre el material en polvo directamente sobre la cinta transportadora, y poder volver a usar la misma cinta transportadora en los siguientes ciclos de prensado; lo anterior se logra con el dispositivo expresado en la reivindicación 1.The main objective of the present invention is to eliminate the disadvantages described above providing a device for loading powder material, which allow a high pressure pressing cycle to be carried out on the powder material directly on the conveyor belt, and be able to use the same conveyor belt again in the following pressing cycles; The above is achieved with the device expressed in claim 1.
