Antecedentes de Ia invenciónBackground of the invention
Son sobradamente conocidos los muebles expositores para piezas cerámicas. Estas piezas cerámicas, para una mayor percepción de las características en las operaciones de compra venta, se exponen en su mayoría de grandes dimensiones, Io que hace que tengan un peso elevado, teniendo que colocarse sobre expositores con suficiente fuerza como para sustentarlas. Una vez colocadas las piezas cerámicas en el expositor, éste resulta muy pesado dadas las piezas y el propio expositor que debe soportar el peso, para Io que se suelen colocar medios de deslizamiento en el expositor para facilitar su movimiento.Exhibitor furniture for ceramic pieces are well known. These ceramic pieces, for a greater perception of the characteristics in the purchase and sale operations, are mostly exposed in large dimensions, which makes them have a high weight, having to be placed on display stands with enough force to support them.

El modelo de utilidad ES 102861 OU describe un mueble expositor constituido por una estructura prismático abierta frontalmente, en Ia que se alojan una pluralidad de paneles rectangulares que incluyen en sus dos superficies los artículos a exponer, y cuyos paneles adoptan una posición vertical, paralela entre sí. Dichos paneles poseen unos medios conjugados que facultan el deslizamiento individual de los paneles desde Ia posición de almacenado hasta una posición parcialmente sobresaliente de Ia estructura, limitada por un tope. Además, los paneles incluyen medios que facultan el giro unitario de 360° del panel seleccionado sobre un eje vertical virtual de simetría, y el consiguiente posicionado de dicho panel en un plano transversal para Ia exposición de una u otra cara del mismo, siendo útiles ambas. Estos modelos anteriores, así como otros muchos existentes en el mercado, se fabrican preferentemente de materiales metálicos, capaces de soportar el peso de las piezas. De este modo, resultan muy pesados, conThe utility model ES 102861 OU describes a display cabinet constituted by a prismatic structure open frontally, in which a plurality of rectangular panels are housed that include the items to be exhibited on their two surfaces, and whose panels adopt a vertical, parallel position between yes. Said panels have conjugated means that allow the individual sliding of the panels from the stored position to a partially outstanding position of the structure, limited by a stop. In addition, the panels include means that allow the 360 ° unitary rotation of the selected panel on a virtual vertical axis of symmetry, and the consequent positioning of said panel in a transverse plane for the exposure of one or another face thereof, both being useful . These previous models, as well as many others existing in the market, are preferably made of metallic materials, capable of supporting the weight of the pieces. In this way, they are very heavy, with
dificultad para mover y los inconvenientes que conlleva a Ia hora de montarlos y desmontarlos.difficulty to move and the inconveniences that it entails when assembling and disassembling them.
Existen otros expositores, que para intentar solucionar estos problemas, se fabrican con algunos componentes plásticos. Es el caso por ejemplo del modelo de utilidad ES 1064600U, que consiste en un panel ligero para expositores de productos cerámicos que comprende un marco exterior, provisto de medios de unión por articulación o deslizamiento a un mueble o estructura portador de dichos marcos, una superficie externa a dos caras formada por sendas láminas de densidad media, siendo dicha superficie externa apta para adherir al menos una pieza cerámica plana, y siendo dicha superficie externa igualmente apta para adherir una fotografía, y una estructura ligera interior de separación entre las caras externas formando el conjunto una estructura tipo sandwich. La estructura ligera interior está formada de forma alveolar por láminas de cartón, papel, plástico o materiales finos dispuestos entre dos paredes externas.There are other exhibitors, which to try to solve these problems, are manufactured with some plastic components. This is the case, for example, of the utility model ES 1064600U, which consists of a lightweight panel for exhibitors of ceramic products comprising an outer frame, provided with joint means by articulation or sliding to a piece of furniture or structure carrying said frames, a surface external two-sided formed by two sheets of medium density, said external surface being able to adhere at least one flat ceramic piece, and said external surface being equally suitable for adhering a photograph, and a light internal separation structure between the external faces forming the whole a sandwich structure. The light interior structure is formed in a honeycomb by sheets of cardboard, paper, plastic or fine materials arranged between two external walls.
De este modo, este último modelo de utilidad podría resolver el problema de Ia exposición sobre paneles pesados, siendo estos paneles más ligeros para permitir el transporte más fácil y menos costoso. Aun así, el conjunto general, necesita de un marco exterior que rodea el panel, no aguantando por sí solo el peso de los materiales a exponer.Thus, this last utility model could solve the problem of exposure on heavy panels, these panels being lighter to allow easier and less expensive transportation. Even so, the general set needs an outer frame that surrounds the panel, not supporting the weight of the materials to be exposed.
Otro tipo de expositores para piezas cerámicas conocidos, son los muebles expositores tipo "libro", verticales, que presentan un marco que se une a una base por al menos dos puntos, donde en el interior del marco se incluyen los productos a exponer por gravedad, algunas veces mediante otro marco interno. Es el caso por ejemplo del modelo 1046977 U, que describe un mueble expositor perfeccionado, para piezas cerámicas planas, formado a partir de un bastidor estructural de una pieza, realizándose Ia unión de los elementos constitutivos del bastidor mediante soldadura, dotado de unas patas y sobre el cual se acoplan un número adecuado de paneles expositores, que permiten IaAnother type of exhibitors for known ceramic pieces, are the "book" type, vertical display units, which have a frame that joins a base by at least two points, where the products to be exposed by gravity are included inside the frame , sometimes through another framework internal. This is the case, for example, of model 1046977 U, which describes an improved display cabinet, for flat ceramic pieces, formed from a one-piece structural frame, making the union of the constituent elements of the frame by welding, provided with legs and on which an adequate number of display panels are coupled, which allow Ia

Estos paneles que sustentan las piezas a exponer han de ser resistentes, además de encontrarse apoyados al menos sobre dos puntos extremos, en Ia base de sustentación y en Ia parte superior en el caso de paneles tipo "libro", o en los dos extremos laterales, en el caso del modelo ES 1058255 U. Además, normalmente, se usa un marco perimetral alrededor de las piezas a exponer, o incluso alrededor del panel para su colocación en las bases de sustentación. Un único apoyo de los paneles no permitiría el correcto deslizamiento, además de no resistir el peso transportado.These panels that support the pieces to be exhibited must be resistant, in addition to being supported at least on two extreme points, on the base of support and on the upper part in the case of "book" type panels, or on the two lateral ends , in the case of model ES 1058255 U. In addition, normally, a perimeter frame is used around the pieces to be exposed, or even around the panel for placement in the support bases. A single support of the panels would not allow the correct sliding, besides not resisting the transported weight.
Descripción de Ia invenciónDescription of the invention
La presente trata de un procedimiento de fabricación de dispositivos expositores para piezas cerámicas, así como de los dispositivos expositores obtenidos a través de dicho procedimiento. El producto obtenido se destina a Ia utilización como soporte publicitario, en puntos de venta o promoción de cerámica, parquet o materiales de construcción. El expositor se obtiene a través de Ia inyección de materiales plásticos, pudiendo combinarse con otros materiales metálicos. De este modo, se consigue un conjunto expositor ligero y fácil de transportar y manejar, de peso inferior a los existentes actualmente siendo de tamaño similar. Está pensado principalmente para expositores de más de 400 gramos en conjunto, consiguiendo un expositor plástico y robusto a Ia vez, capaz de aguantar el peso de las piezas cerámicas que exhibe.This is a manufacturing process for display devices for ceramic pieces, as well as the display devices obtained through said procedure.

It is mainly intended for exhibitors of more than 400 grams together, getting a plastic and robust display at the same time, able to withstand the weight of the ceramic pieces it exhibits.
Mediante el proceso de fabricación de los paneles expositores se reducen los costes, fabricándolos de grandes dimensiones, y sustituyendo partes de los expositores actuales de acero por componentes plásticos comoThrough the manufacturing process of the display panels, costs are reduced, making them large, and replacing parts of the current steel exhibitors with plastic components such as

Además de una alta resistencia al calor, se caracteriza por su gran dureza y resistencia a Ia abrasión, así como resistencia a Ia fatiga, muy buenas condiciones de deslizamiento, gran resistencia a bajas temperaturas, a Ia fricción y al desgaste.fiberglass reinforced polyamides obtained by injection. A product of great rigidity and strength is thus obtained. In addition to high heat resistance, it is characterized by its high hardness and resistance to abrasion, as well as resistance to fatigue, very good sliding conditions, high resistance to low temperatures, friction and wear.
Debido a Ia gran diversidad de dispositivos expositores demandados, de diferentes características geométricas, colores, etc., e incluso debido a las necesidades de transporte y manipulación, se lleva a cabo el procedimiento de Ia invención a través de Ia inyección, de manera que puede fabricarse una pluralidad de piezas diferentes con gran rapidez, bajos costes y altos niveles de producción, e incluso conseguir geometrías complicadas que no sería posible conseguir con otros métodos.Due to the great diversity of demanded display devices, of different geometric characteristics, colors, etc., and even due to the needs of transport and handling, the process of the invention is carried out through the injection, so that it can manufacture a plurality of different parts with great speed, low costs and high levels of production, and even get complicated geometries that would not be possible to achieve with other methods.
Para llevar a cabo el procedimiento de Ia invención se hace necesaria una máquina de inyección y un molde. Dicho molde llevará una cavidad cuya forma y tamaño sea Ia adecuada de acuerdo a Ia forma de Ia pieza que se desea obtener. Se calientan los pellets del material a transformar, poliamida o similar, para transformarlo en una especie de masa fundida, que llenará Ia cavidad del molde, solidificando y manteniendo Ia forma final de dicho molde. Cuando el plástico está en el molde se enfría por medio de circuitos donde fluye un refrigerante como puede ser agua, abriendo finalmente el molde para obtener una pieza sólida.To carry out the process of the invention, an injection machine and a mold are necessary. Said mold will have a cavity whose shape and size is adequate according to the shape of the piece to be obtained. The pellets of the material to be transformed, polyamide or the like, are heated to transform it into a kind of melt, which will fill the mold cavity, solidifying and maintaining the final shape of said mold. When the plastic is in the mold it cools through circuits where a coolant such as water flows, finally opening the mold to obtain a solid piece.
Para esta operación Ia parte fija o de inyección es a temperatura de al menos 220° y Ia parte móvil o de expulsión estará entre 40 y 65°, preferentemente 50°, regulándolo mediante Ia refrigeración de placas.For this operation the fixed or injection part is at a temperature of at least 220 ° and the mobile or ejection part will be between 40 and 65 °, preferably 50 °, regulating it by means of plate cooling.
Con los sistemas hidráulicos se controlan el movimiento de los sistemas de inyección de cierre, y con los sistemas eléctricos se controlan las temperaturas, flujo de agua y aceite.With the hydraulic systems the movement of the closing injection systems is controlled, and with the electrical systems the temperatures, water and oil flow are controlled.
De este modo, se inyecta el plástico en el molde vacío y cerrado inicialmente, abriéndose Ia válvula, donde el husillo que actúa como pistón, y se transporta el material a través de Ia boquilla hacia las cavidades del molde.In this way, the plastic is injected into the empty mold and initially closed, opening the valve, where the spindle acts as a piston, and the material is transported through the nozzle to the mold cavities.
La presión se mantiene constante para lograr que Ia pieza tenga las dimensiones adecuadas, pues al enfriarse podría contraerse.The pressure is kept constant to ensure that the piece has the appropriate dimensions, because when it cools it could contract.
A continuación a presión se elimina y Ia válvula se cierra. El husillo gira para cargar el material y al girar también retrocede. La pieza en el molde termina de enfriarse. La prensa libera Ia presión y el molde se abre, expulsando las barras Ia parte moldeada fuera de Ia cavidad.Then the pressure is eliminated and the valve is closed. The spindle rotates to load the material and when turning it also goes back. The piece in the mold finishes cooling. The press releases the pressure and the mold opens, expelling the bars the molded part out of the cavity.

La presente invención trata de un procedimiento de fabricación de dispositivos expositores para piezas cerámicas, así como del dispositivo expositor obtenido de dicho procedimiento.The present invention deals with a manufacturing process for display devices for ceramic pieces, as well as the display device obtained from said process.
El procedimiento de fabricación de dispositivos expositores para piezas cerámicas es de especial aplicación para aquellos conjuntos que superan los 400 gramos de peso total. Esta es una de las ventajas de Ia invención, pues gracias a su ligereza rigidez, permite fabricar grandes expositores.The manufacturing process of display devices for ceramic pieces is of special application for those assemblies that exceed 400 grams of total weight. This is one of the advantages of the invention, because thanks to its light stiffness, it allows to manufacture large exhibitors.
Para llevar a cabo el procedimiento de Ia invención se hace necesaria una unidad de inyección (4) para el material plástico (11 ). Su función es Ia de fundir, mezclar e inyectar el material plástico (11 ) a través de husillos de diferentes características según el tipo de material plástico (11 ) que se inyecte. Para ello, se ha de tener en cuenta Ia temperatura de procesamiento según el material plástico (11 ) que se utilice, así como Ia presión y variación de volumen del mismo. El proceso de fusión genera un aumento de calor del polímero, con el consiguiente aumento de temperatura, disminuyendo Ia viscosidad del material plástico (11 ) fundido.In order to carry out the process of the invention, an injection unit (4) for the plastic material (11) is necessary. Its function is to melt, mix and inject the plastic material (11) through spindles of different characteristics according to the type of plastic material (11) that is injected. For this, the processing temperature must be taken into account according to the plastic material (11) used, as well as the pressure and volume variation thereof. The melting process generates an increase in heat of the polymer, with the consequent increase in temperature, reducing the viscosity of the molten plastic material (11).

Así pues, para cambiar Ia forma de Ia pieza (12) final a obtener, basta con cambiar el molde (3) de Ia unidad de inyección (4). Esto hace que el proceso de fabricación de diferentes expositores cerámicos sea rápido y con bajos costes una vez obtenidos los moldes.The mold (3) is the part of the injection unit (4) in which the solid part (12) is generated, so that depending on the shape of its cavity one form or another of the final piece will be obtained. Thus, to change the shape of the final piece (12) to be obtained, simply change the mold (3) of the injection unit (4). This makes the manufacturing process of different ceramic exhibitors fast and with low costs once the molds are obtained.
El procedimiento para Ia fabricación de los dispositivos expositores comprende las siguientes etapas:The process for manufacturing the display devices comprises the following stages:

(e) se enfría el molde (3) por circuitos donde fluye un refrigerante, preferentemente agua, que mantiene Ia temperatura del molde atemperado(e) the mold (3) is cooled by circuits where a refrigerant flows, preferably water, which keeps the temperature of the mold tempered
(f) se abre el molde (3) y se expulsa Ia pieza sólida (12) obtenida fuera del mismo.(f) the mold (3) is opened and the solid part (12) obtained outside it is ejected.
El material plástico utilizado en el procedimiento es poliamida 6.6, preferentemente reforzada con fibra de vidrio al 30%.The plastic material used in the process is polyamide 6.6, preferably reinforced with 30% glass fiber.
El dispositivo expositor obtenido mediante el procedimiento anteriormente descrito comprende al menos un panel (1 ) que conforma Ia propia estructura del expositor, destinado a Ia sustentación de las piezas a exponer, y que se obtiene por inyección de cualquier tipo de polímero plástico, donde una base (2) de apoyo sujeta por Ia parte inferior el citado panel (1 ), permitiendo el intercambio del mismo. Generalmente, el panel (1 ) estará formado por dos piezas intercambiables, de manera que se puede cambiar una de ellas para poner otras piezas a exponer manteniendo las del lado contrario.The display device obtained by the procedure described above comprises at least one panel (1) that forms the structure of the display, intended for the lifting of the pieces to be exposed, and which is obtained by injection of any type of plastic polymer, where a support base (2) holds the aforementioned panel (1), allowing the exchange thereof. Generally, the panel (1) will be formed by two interchangeable pieces, so that one of them can be changed to put other pieces to be exhibited keeping those on the opposite side.
En una realización preferente de Ia invención, y según se observa en IaIn a preferred embodiment of the invention, and as observed in Ia
Figuras 2, el expositor propuesto comprende al menos un panel (1 ) obtenido por inyección de cualquier tipo de polímero plástico, formado por dos piezas de inyección, y destinado a Ia sustentación de las piezas a exponer. Este panel (1 ) al ser de material polimérico, es un panel ligero, consiguiendo de este modoFigures 2, the proposed display comprises at least one panel (1) obtained by injection of any type of plastic polymer, formed by two injection pieces, and intended for supporting the pieces to be exposed.

This type of display is known as "book type". It comprises a lower clamping means (7), a support and displacement base (2) for each of the panels (1), articulated jointly to the lower clamping means (7) and with rolling means at its free end, and a panel (1) obtained by injection of any type of plastic polymer according to the procedure described above, formed by two pieces, fixed on its lower part to the support base (2), said panel (1) being interchangeable, and forming it The exhibitor's own structure that supports the pieces to be exhibited.
El medio de sujeción inferior (7) puede materializarse en un perfil en forma de doble "T" (ver Figura 6), con una pluralidad de orificios destinados a Ia articulación y sustentación de Ia base (2) de apoyo por medio de un pasador que se introduce a través de dichos orificios y de Ia base (2) por su lugar habilitado. También podría materializarse dicho medio de sujeción (7), por ejemplo, en un pasador cilindrico con una placa inferior a modo de base para su sujeción al suelo (ver Figura 7), sobre cuyo pasador se introduce articuladamente Ia base (2) por su lugar habilitado, disponiendo por cada panel (1 ) de un pasador y placa inferior. Además, igual que en Ia realización preferente anterior, el panel (1 ) puede disponer de medios (8) para facilitar su desplazamiento. The lower clamping means (7) can be realized in a double "T" shaped profile (see Figure 6), with a plurality of holes intended for the articulation and support of the support base (2) by means of a pin which is introduced through said holes and the base (2) for its enabled place.
