Abstract

Lining material (3, 3) is applied to a continuously extruded core material (7), the resulting material is supplied to an intermittently operated, cooled mould press (9-11) and the profiled strip is fragmented and the resulting profiled parts (14, 15) are cooled. A process for making profiled parts, especially structured parts with a core of virgin and/or recycled plastic material mixed with cardboard, sawdust or similar material and a cover layer formed by a laminar lining comprises the following steps: (a) continuous extrusion of the core material (b) applying one or more lining layers onto the extruded core material (c) moulding by intermittent pressing in combination with cooling so that the extruded material has the desired final dimensions at the press exit (d) fragmenting the profiled strip and (e) cooling the profiled fragments or parts. An independent claim is also included for the process apparatus comprising a standard extruder (1) has one or more rolls (2, 2) at its exit for supplying the lining material from reels (4, 4) and these rolls are followed by a forming device (5) used to convert one of the lining material sheets into a tube. An intermittently operated mould press forms an extension of the forming device and includes mould tools corresponding to the type of profiled part to be produced. A printing unit (16) for continuous printing of the profiled part is located after the press and followed by a cutting device (18) for dividing the profiled part into fragments.

Description

Método para la fabricación de piezas perfiladas e instalación para la puesta en práctica del mismo.Method for manufacturing profiled parts and installation for the implementation of it.

Objeto de la invenciónObject of the invention

La presente invención se refiere a un nuevo método para la fabricación de piezas perfiladas, como por ejemplo para la fabricación de moldes para encofrar cornisas de hormigón, cantoneras para embalaje, etc, obtenidas utilizando como materia prima principalmente cartón y plástico, provenientes de productos reciclables o no, materias primas que constituyen el núcleo de los perfiles a obtener, que opcionalmente quedan recubiertos por al menos una lámina en funciones de forro, que en el proceso queda perfectamente adherida al núcleo, recubriendo totalmente este último.The present invention relates to a new method for manufacturing profiled parts, such as for the manufacture of molds to form concrete cornices, corners for packaging, etc., obtained using as material premium mainly cardboard and plastic, coming from products recyclable or not, raw materials that constitute the core of the profiles to be obtained, which are optionally covered by the less a sheet in function of lining, which in the process remains perfectly adhered to the core, completely covering this latest.

La invención concierne también a la instalación para la puesta en práctica de dicho método.The invention also concerns the installation for the implementation of said method.

El objeto de la invención es conseguir un notable abaratamiento de costos en el proceso, fundamentalmente basado en una instalación considerablemente más simple, y todo ello paralelamente a una óptima funcionalidad, que asegura un mejor acabado del producto final.The object of the invention is to achieve a remarkable cost reduction in the process, fundamentally based on a considerably simpler installation, and all this parallel to optimal functionality, which ensures better finish of the final product.

Antecedentes de la invenciónBackground of the invention

Son conocidas piezas perfiladas a base de un núcleo de material termoplástico, cargado o no, núcleo que queda protegido por lo menos con una hoja de un material flexible.Profiled pieces based on a core of thermoplastic material, loaded or not, remaining core protected with at least one sheet of flexible material.

Piezas perfiladas de este tipo se daban ya por conocidas en la patente de invención española 523.121 en la que se describe un procedimiento de fabricación en continuo de los mismos.Profiled pieces of this type were already given by known in Spanish invention patent 523.121 in which describes a continuous manufacturing process of same.

Específicamente dicho procedimiento comienza con el calentamiento del material termoplástico, para llevarlo hasta su temperatura de reblandecimiento, y en un proceso de extrusión se consigue en continuo el perfil que se desea obtener, aplicando a la salida de la hilera de la extrusora una pareja de láminas de cubrición que evitan deformaciones en el núcleo por el estado semi-fundido del material constitutivo del mismo, según una técnica que se da también por conocida en dicha patente, para seguidamente someter al perfil a una fase de calandrado donde adquirirá una sección sensiblemente próxima a la definitiva, la cual se consigue finalmente en una fase de conformado, a una temperatura inferior a la de calandrado y donde participan, como en dicho calandrado, rodillos con el perfil de la pieza en continuo a obtener.Specifically said procedure begins with the heating of the thermoplastic material, to take it to its softening temperature, and in an extrusion process continuously obtain the profile you want to obtain, applying to the exit of the extruder row a pair of sheets of covering that prevent deformations in the nucleus by the state semi-molten of the constituent material thereof, according to a technique that is also known in said patent, to then submit the profile to a calendering phase where will acquire a section substantially close to the final one, the which is finally achieved in a forming phase, at a temperature below calendering and where they participate, as in said calendering, rollers with the profile of the piece in continuous to obtain.

Tanto los rodillos de calandrado como los rodillos de conformado constituyen piezas de precisión, de importante costo y mantenimiento, que repercuten negativamente en la rentabilidad del proceso.Both the calendering rollers and the forming rollers constitute precision parts, of significant cost and maintenance, which have a negative impact on The profitability of the process.

Descripción de la invenciónDescription of the invention

El método que la invención propone resuelve de forma plenamente satisfactoria la problemática anteriormente expuesta, en base a dos características complementarias, por un lado a la no utilización de rodillos conformadores, y por otro lado a la tampoco utilización de una fase de calandrado, lo que trae consigo la no necesidad de disponer tampoco de rodillos calandradores.The method proposed by the invention resolves the problem was fully satisfactory before exposed, based on two complementary characteristics, by a side to the non-use of forming rollers, and on the other hand to the use of a calendering phase, which brings I don't need to have rollers either calenders.

Para ello y de forma más concreta el método de la invención, partiendo de una fase de extrusión en continuo y de aplicación cuando sean necesario de una envolvente laminar, fases ineludibles y de dominio público, centra sus características en el hecho de que la conformación de la pieza perfilada se lleva a cabo en una fase de moldeo por prensado intermitente y simultánea refrigeración, sometiéndose seguidamente al perfil en continuo a una fase de corte, y al definitivo enfriamiento del mismo.To do this and more specifically the method of invention, starting from a continuous extrusion phase and from application when necessary of a laminar envelope, phases unavoidable and public domain, focuses its characteristics on the fact that the shaping of the profiled part is carried out in a phase of intermittent and simultaneous pressing molding cooling, then submitting the continuous profile to a cutting phase, and the definitive cooling of the same.

La citada fase de moldeo por prensado intermitente se lleva a cabo con la colaboración de una prensa, que con una apertura tipo tijera o en paralelo, es capaz de presionar la tira de material, dotar a esta última de la configuración prevista para la misma y hacer estable dicha configuración mediante enfriamiento de la tira en el seno de la propia prensa.The aforementioned pressing molding phase intermittent is carried out with the collaboration of a press, which With a scissor or parallel opening, it is able to press the strip of material, provide the latter with the configuration planned for it and make such configuration stable by cooling of the strip within the press itself.

Dado que el proceso de extrusión se produce en continuo, la citada prensa forma parte de un carro móvil, que en situación de cierre para la misma se mueve a la misma velocidad y en el mismo sentido que la tira de material, con una amplitud de movimiento suficiente para que el tiempo de permanencia de la pinza cerrada sea el adecuado para que el enfriamiento de la misma asegure la definitiva estabilidad de su forma, mientras que en fase de apertura para la prensa el carro se desplaza en sentido contrario y a alta velocidad para cerrarse sobre un nuevo sector de tira de material y repetir su ciclo operativo.Since the extrusion process occurs in Continuous, the aforementioned press is part of a mobile car, which in closing situation for it moves at the same speed and in the same sense as the strip of material, with an amplitude of enough movement so that the clamp's residence time closed is suitable for cooling it ensure the definitive stability of its shape, while in phase opening for the press the car moves in the direction opposite and at high speed to close on a new sector of Strip material and repeat its operating cycle.

A la salida de la prensa de moldeo se sitúa un mecanismo de arrastre, consistente en al menos una pareja de ruletas que, debidamente motorizadas, traccionan de la pieza perfilada, sin que dichas ruletas deban copiar las formas correspondientes al perfil de la pieza por cuanto que ésta ya se encuentra debida y definitivamente conformada.At the exit of the molding press there is a drag mechanism, consisting of at least one pair of roulettes that, properly motorized, pull the piece profiled, without said roulettes having to copy the shapes corresponding to the profile of the piece because it is already finds due and definitely conformed.

Tras este mecanismo de arrastre o tiraje del perfil se sitúa una unidad de corte, que fragmenta convenientemente el perfil continuo, en tramos de la longitud prevista.After this drag or pull mechanism of the profile is a cutting unit, which conveniently fragments the continuous profile, in sections of the expected length.

De acuerdo con una variante de realización, el mecanismo de arrastre citado puede ser sustituido por una segunda fase de prensado intermitente, con una segunda prensa que funcione desfasada o alternativamente con la primera, de manera que mientras la primera prensa se encuentre en situación inoperante o de apertura, la segunda se encuentra en situación de cierre y arrastre, y viceversa, con lo que se consigue alargar el tiempo de enfriamiento de la pieza perfilada, al estar la segunda prensa también refrigerada, al igual que la primera.According to an embodiment variant, the cited drag mechanism can be replaced by a second intermittent pressing phase, with a second press that works outdated or alternatively with the first one, so that while the first press is in an inoperative situation or opening, the second is in a situation of closing and dragging, and vice versa, with which it is possible to lengthen the time of cooling of the profiled part, being the second press also refrigerated, like the first.

Realización preferente de la invenciónPreferred Embodiment of the Invention

A la vista de las figuras reseñadas, y más concretamente de la figura 1, puede observarse como en la citada instalación participa una máquina extrusora (1), de cualquier tipo convencional, de uno o dos husillos con distintas longitudes y diámetros, según el molde de cornisa a fabricar, en su caso del molde de cantonera o elemento de que se trate, y con diferentes temperaturas de fusión en función de las materias primas usadas, que pueden ser materias plásticas nuevas y recicladas de distintos tipos de plástico y con distintas mezclas tales como cartón, serrín, etc.In view of the figures outlined, and more specifically of figure 1, it can be observed as in the aforementioned installation involves an extruder machine (1), of any type conventional, with one or two spindles with different lengths and diameters, according to the cornice mold to be manufactured, where appropriate corner mold or element in question, and with different melting temperatures depending on the raw materials used, that can be new and recycled plastic materials of different types of plastic and with different mixtures such as cardboard, sawdust, etc.

A la salida de la extrusora (1) se sitúan una pareja de rodillos (2), (2'), uno superior y otro inferior, destinados a suministrar respectivas láminas de forro (3-3') provenientes de respectivas bobinas (4-4') y asistidas, al menos una de ellas, en el ejemplo de realización práctica elegido la inferior (3'), por un conformador (5) que con un extremo perfectamente plano, el más próximo al rodillo (2') correspondiente, adopta en su extremo opuesto (6) una configuración tubular, para que dicho forro (5) se adapte a la tira de material (7) generada por la extrusora (1).At the exit of the extruder (1) a pair of rollers (2), (2 '), one upper and one lower, intended to supply respective liner sheets (3-3 ') from respective coils (4-4 ') and assisted, at least one of them, in the example of practical implementation chosen the lower one (3 '), by a shaper (5) that with a perfectly flat end, the most next to the corresponding roller (2 '), adopts at its end opposite (6) a tubular configuration, so that said liner (5) is adapt to the strip of material (7) generated by the extruder (1).

En la figura 1, se ha representado la disposición relativa entre las láminas de forro (3-3') y la tira de material (7) constitutiva del núcleo, a la entrada y a la salida del conformador (5).In figure 1, the arrangement has been represented relative between the liner sheets (3-3 ') and the strip of material (7) constituting the core, at the entrance and at the output of the shaper (5).

A continuación de dicho conformador (5) se establece la prensa de moldeo en continuo, en la que, sobre una plataforma fija (8) es desplazable longitudinal y alternativamente la prensa propiamente dicha materializada en un plato inferior (9) consistente en un carro desplazable sobre la plataforma (8) por ejemplo a través de ruedas (10), plato inferior (9) con el que colabora un plato superior (11), que puede ser desplazable paralelamente al plato inferior (9) o puede estar relacionado con el mismo mediante una articulación tipo tijera, como se la representada en la figura 1, incorporando en cualquier caso cada uno de estos platos (9) y (11) respectivos postizos interiores (12) y (13), recambiables, que por ejemplo pueden configurar entre ellos el perfil (14) correspondiente a una cantonera, como la mostrada en la figura 1, el perfil correspondiente a un molde (15) para encofrado de cornisas, como el mostrado en la figura 2, o cualquier otro tipo de perfil.Following said shaper (5) is establishes the continuous molding press, in which, on a fixed platform (8) is movable longitudinally and alternatively the press itself materialized in a lower plate (9) consisting of a movable car on the platform (8) by example through wheels (10), bottom plate (9) with which a top plate (11) collaborates, which can be movable parallel to the bottom plate (9) or it may be related to the same through a scissor joint, as is the represented in figure 1, incorporating in any case each of these dishes (9) and (11) respective inner hairpieces (12) and (13), replaceable, which for example can configure between them the profile (14) corresponding to a corner, as shown in Figure 1, the profile corresponding to a mold (15) for cornices formwork, as shown in figure 2, or any Another type of profile.

Los platos (9) y (11) estarán refrigerados para conseguir que, paralelamente al prensado y conformación de la tira de material (7) se consiga la estabilidad formal de la misma.The plates (9) and (11) will be refrigerated to get that, parallel to the pressing and forming of the strip of material (7) its formal stability is achieved.

Como ya se ha dicho con anterioridad, el carro constituido por la prensa propiamente dicha (9-10) se desplaza sobre la plataforma base y fija (8) en el sentido de avance de la tira de material (7), a una velocidad acorde con la determinada por la extrusora (1), de manera que la prensa cerrada acompaña a la tira (7) durante un trayecto de aproximadamente unos 30 cm, suficiente para que se produzca la conformación y estabilización formal de un segmento de tira (7), e inmediatamente a continuación los platos (9) y (11) de la prensa se abren, en la posición mostrada en la figura 1, y retornan bruscamente a su posición inicial, desplazándose en sentido contrario sobre la plataforma (8), sin afectar en absoluto a la tira de material (7), para cerrarse nuevamente sobre dicha tira al alcanzar su posición extrema más próxima a la extrusora (1), repitiendo desde allí su ciclo operativo, es decir cerrándose sobre la tira de material (7) y desplazándose nuevamente a la velocidad de dicha tira.As previously stated, the car constituted by the press itself (9-10) moves on the base and fixed platform (8) in the sense of feed of the strip of material (7), at a speed consistent with the determined by the extruder (1), so that the press closed accompany the strip (7) during a journey of approximately 30 cm, enough for conformation to occur and formal stabilization of a strip segment (7), and immediately then the plates (9) and (11) of the press open, in the position shown in figure 1, and they return sharply to their initial position, moving in the opposite direction on the platform (8), without affecting the material strip (7) at all, to close again on said strip when reaching its position extreme closest to the extruder (1), repeating from there its operating cycle, that is, closing on the strip of material (7) and  moving again at the speed of said strip.

La pieza perfilada (14-15), a su salida de la prensa de moldeo, pasa por una estación de tiraje o tracción (16), compuesta por dos campos de ruletas motorizadas (17) que actúan como medios arrastradores de dicha pieza perfilada (14-15), la cual pasa finalmente por un mecanismo de corte (18), donde se produce la definitiva fragmentación de la misma.The profiled piece (14-15), at its exit from the molding press, pass through a print station or traction (16), consisting of two fields of motorized roulettes (17) which act as dragging means of said profiled piece (14-15), which finally goes through a mechanism of court (18), where the definitive fragmentation of the same.

Una vez fragmentada la pieza perfilada (14-15) de que se trate, los segmentos obtenidos pasan a una noria vertical con varios puestos, que permite enfriarlos mientras circulan, antes de ser empaquetados.Once the profiled piece is fragmented (14-15) in question, the segments obtained they pass to a vertical ferris wheel with several positions, which allows cool them while they circulate, before being packed.

En determinados supuestos prácticos, como por ejemplo para la fabricación de "tacos" para palets y otros similares, no es innecesario que las piezas perfiladas incorporen una envolvente (3-3'), como las anteriormente citadas, por lo que en este caso la instalación carecerá del sistema de alimentación de dichas láminas de forro, es decir de los rodillos (2), los soportes para las bobinas (4) y el conformador (5), de manera que en este caso la masa continua (7) de material, a su salida de la extrusora (1), penetra directamente en la prensa de moldeo en continuo (9-11), como se observa en la figura 3.In certain practical cases, as per example for the manufacture of "tacos" for pallets and others similar, it is not unnecessary for profiled parts to incorporate an envelope (3-3 '), as before cited, so in this case the installation will lack the feeding system of said liner sheets, i.e. rollers (2), the supports for the coils (4) and the shaper (5), so that in this case the continuous mass (7) of material, to its exit from the extruder (1), penetrates directly into the press of continuous molding (9-11), as seen in the figure 3.

Por otro lado, se ha previsto también la posibilidad de instalación mostrada en la figura 4, en la que la estación de tiraje (16) ha sido eliminada y sustituida por una segunda prensa continua (9'-11'), desplazable igualmente sobre la plataforma base y fija (8) pero de funcionamiento alternativo con la prensa (9-11), es decir que mientras esta última se encuentre en situación de apertura, es decir en situación inoperante, es la segunda prensa (9'-11') la que está en situación de cierre, provocando con su movimiento el arrastre de la tira de material (14-15), y a término de su recorrido, cuando se abre, es cuando la primera prensa (9-11) se cierra y continua el arrastre de la tira de material.On the other hand, the installation possibility shown in figure 4, in which the print station (16) has been eliminated and replaced by a second continuous press (9'-11 '), movable also on the base and fixed platform (8) but of alternative operation with the press (9-11), is say that while the latter is in a situation of opening, that is, in an inoperative situation, is the second press (9'-11 ') which is in a closed situation, causing the drag of the strip of material with its movement (14-15), and at the end of its journey, when opens, is when the first press (9-11) closes and the drag of the strip of material continues.

Con ello se consigue, por un lado que la fase de moldeo sea doble, realizándose mayoritariamente en la primera prensa de moldeo (9-11), y rematándose en la segunda prensa de moldeo (9'-11'), a la vez que se alarga el tiempo de enfriamiento al estar ambas prensas refrigeradas, con lo que la estabilidad formal de la tira continua de material, a la salida de la instalación, se ve notablemente potenciada.This achieves, on the one hand, that the phase of molding be double, mostly in the first molding press (9-11), and finishing off in the second molding press (9'-11 '), while lengthens the cooling time when both presses are refrigerated, so that the formal stability of the strip continues of material, at the exit of the installation, it looks remarkably boosted
