OBJETO DE LA INVENCIÓNOBJECT OF THE INVENTION
La presente invención se refiere a un disposi¬ tivo pulidor de perfiles, de especial aplicación en el ámbito de la carpintería, y más concretamente de la carpintería de madera, dispositivo que permite que la pulidora a que se encuentre asociado resulte adaptable a cualquier tipo de perfil, sin necesidad de mecanizado previo de dicha máquina.The present invention relates to a profile polishing device, of special application in the field of carpentry, and more specifically of wood carpentry, a device that allows the polisher to which it is associated to be adaptable to any type of profile, without prior machining of said machine.
El dispositivo pulidor que se preconiza es aplicable al pulido de todo tipo de perfiles, tales como pasamanos, tapajuntas, molduras, etc.The polishing device that is recommended is applicable to the polishing of all types of profiles, such as handrails, flashing, moldings, etc.
ANTECEDENTES DE LA INVENCIÓNBACKGROUND OF THE INVENTION
De acuerdo con la tecnología actual, la máxima calidad en el pulido de perfiles de madera, como los anteriormente citados u otros similares, se logra con la utilización de máquinas rectificadoras tangenciales ¿le perfiles, que actúan por la rotación de un juego de pastillas dispuestas radialmente, previamente mecani¬ zadas de acuerdo con el perfil que han de pulir, y con un abrasivo convenientemente fijado, generalmente por encolado, a la superficie de trabajo.According to current technology, the highest quality in the polishing of wood profiles, such as those mentioned above or similar ones, is achieved with the use of tangential grinding machines, which profiles, which act by rotating a set of arranged tablets radially, previously machined according to the profile to be polished, and with an abrasive conveniently fixed, usually by gluing, to the work surface.
La problemática fundamental que presentan estas máquinas se centra en el hecho de que, además de ser necesario renovar el abrasivo cada vez que se gasta, para cada perfil a pulir en concreto se hace ineludible un juego de pastillas convenientemente mecani-
zadas, lo que trae consigo, obviamente, unos elevados costos de preparación o "programación" de la máquina para cada trabajo en concreto, que tan sólo se justifica cuando se trata de grandes tiradas de perfiles formal y dimensionalmente idénticos, resultando la utilización de tales máquinas totalmente improcedente cuando se trata de tiradas cortas, en cuyo caso la única solución viable es el lijado manual, trabajo muy laborioso e ingrato.The fundamental problem presented by these machines focuses on the fact that, in addition to being necessary to renew the abrasive every time it is spent, for each profile to be polished in particular, a conveniently mechanized set of pads becomes unavoidable. obviously, which entails, obviously, high costs of preparation or "programming" of the machine for each specific job, which is only justified when it comes to large runs of formally and dimensionally identical profiles, resulting in the use of such Machines totally inadmissible when it comes to short runs, in which case the only viable solution is manual sanding, very laborious and ungrateful work.
Es de destacar también, como otro problema de las citadas máquinas rectificadoras tangenciales, que tales máquinas sólo pueden pulir molduras o perfiles rectos, quedando totalmente fuera de sus posibilidades los perfiles o molduras curvadas.It is also noteworthy, as another problem of the aforementioned tangential grinding machines, that such machines can only polish moldings or straight profiles, curved profiles or moldings being completely out of their possibilities.
Constituye también un problema la tendencia de estos sistemas de pulido a redondear los cantos vivos o aristas agudas de las molduras, modificando la estética de las mismas.The tendency of these polishing systems to round the sharp edges or sharp edges of the moldings, modifying their aesthetics, is also a problem.
Los numerosos folletos de propaganda que los fabricantes de estas máquinas publican, son un magnífico documento que refleja el actual estado de la técnica, siendo interesante en tal aspecto el "Catálogo de Maqui¬ naria Española para Trabajar la Madera" 1.989-90, editado por AFEMMA.The numerous propaganda brochures that the manufacturers of these machines publish, are a magnificent document that reflects the current state of the art, being interesting in this aspect the "Catalog of Spanish Machinery for Woodworking" 1989-90, edited by AFEMMA

Para complementar la descripción que se está realizando y con objeto de ayudar a una mejor comprensión de las características del invento, se acompaña a la presente memoria descriptiva, como parte integrante de la misma, una hoja única de planos en la que con carácter ilustrativo y no limitativo y en su única figura se ha representado un despiece en perspectiva de un dispositivo pulidor de perfiles realizado de acuerdo con el objeto de la presente invención.To complement the description that is being made and in order to help a better understanding of the characteristics of the invention, a single sheet of plans is attached as an integral part of it, in which it is illustrative and non-limiting and in its single figure an exploded perspective of a profile polishing device made in accordance with the object of the present invention has been represented.
REALIZACIÓN PREFERENTE DE LA INVENCIÓNPREFERRED EMBODIMENT OF THE INVENTION
A la vista de esta figura puede observarse cómo el dispositivo pulidor que se preconiza está estruc- turado a partir de un árbol (1), acoplable directa o
indirectamente al eje motriz de la máquina pulidora, árbol (1) que, de acuerdo con un ejemplo preferente de realización práctica de la invención, presenta un escalonamiento perimetral sobre el que asienta un primer plato o volante (2), tras el que se define en dicho árbol un eje (3) que a su vez y en correspondencia con su extremidad libre cuenta con otro escalonamiento (4) para acoplamiento de un segundo plato o volante (2' ), que se fija al eje (3) con la colaboración de un tornillo (5) y una arandela (6), tornillo que rosca en el interior hueco (7) del eje (3), a la vez que entre los platos (2-2' ), en la periferia de los mismos y con la colabora¬ ción de orificio (8) operativamente practicados en ellos, se establecen una pluralidad de varillas (9) que configu- ran, como anteriormente se ha dicho, una especie de "jaula de ardilla". No obstante esta solución estructural es meramente ejemplaria y los platos o volantes (2-2") pueden quedar fijados al eje (3) por cualquier otro medio, de la misma manera que las varillas (9) pueden fijarse a los platos o volantes (2-2') por cualquier medio convencional que se estime adecuado o conveniente.In view of this figure, it can be seen how the proposed polishing device is structured from a shaft (1), directly attachable or indirectly to the drive shaft of the polishing machine, shaft (1) which, according to a preferred example of practical embodiment of the invention, has a perimeter step on which sits a first plate or flywheel (2), after which it is defined in said tree an axis (3) which in turn and in correspondence with its free end has another step (4) for coupling a second plate or flywheel (2 '), which is fixed to the axis (3) with the collaboration of a screw (5) and a washer (6), a screw that threads into the hollow interior (7) of the shaft (3), as well as between the plates (2-2 '), at the periphery thereof and with the hole collaboration (8) operatively practiced therein, a plurality of rods (9) are established which, as previously stated, establish a kind of "squirrel cage". However, this structural solution is merely exemplary and the plates or flyers (2-2 ") can be fixed to the shaft (3) by any other means, in the same way that the rods (9) can be fixed to the plates or flyers ( 2-2 ') by any conventional means deemed appropriate or convenient.
En cualquier caso sobre cada varilla (9) se montan una pluralidad de arandelas de lija (10), que en su conjunto y para dicha varilla (9), forman un bloque cilindrico y operativo (11), claramente visible en la figura. De forma más concreta, las citadas arandelas de lija (11) cuentan, para su fijación a la correspon¬ diente varilla (9), con un orificio o agujero (12) acusa- damente excéntrico, de manera que tales arandelas de lija (10), siendo proyectables radialmente hacia afuera por fuerza centrífuga durante el movimiento giratorio del árbol (1 ) , resultan sin embargo retraíbles en magni¬ tud variable y unas más o menos que otras, en función de su incidencia sobre la superficie del perfil a pulir.
retrayéndose cuando dicho perfil las fuerza a ello, pero manteniendo siempre una presión sobre dicho perfil, debido a la citada fuerza centrífuga, con el que se consigue el efecto de pulido previsto.In any case on each rod (9) a plurality of sandpaper washers (10) are mounted, which together and for said rod (9), form a cylindrical and operating block (11), clearly visible in the figure. More specifically, the aforementioned sandpaper washers (11) have, for fixing to the corresponding rod (9), a hole or hole (12) that is markedly eccentric, such that such sandpaper washers (10 ), being projectable radially outward by centrifugal force during the rotating movement of the shaft (1), however, are retractable in varying magnitude and some more or less than others, depending on their incidence on the surface of the profile to be polished. retracting when said profile forces them to it, but always maintaining a pressure on said profile, due to said centrifugal force, with which the expected polishing effect is achieved.
Como complemento de la estructura descrita se ha previsto que las arandelas de lija (10) se monten sobre las varillas (9) con interposición de arandelas distanciadoras (13) que evitan el apelmazamiento entre arandelas de lija (10), y que los orificios (12) de estas últimas cuenten con ojetes metálicos de protección (14), que opcionalmente estarán rasgados en sentido radial y que, como también se ha dicho con anterioridad, preferentemente agruparán a las arandelas de lija (10) por parejas, quedando dichas arandelas con sus superfi¬ cies operativas enfrentadas dentro de cada pareja.As a complement to the described structure, it is provided that the sandpaper washers (10) are mounted on the rods (9) with interposition of spacer washers (13) that prevent caking between sandpaper washers (10), and that the holes ( 12) of the latter, they have metal eyelets for protection (14), which will optionally be torn radially and which, as previously mentioned, will preferably group the sandpaper washers (10) in pairs, leaving said washers with its operating surfaces faced within each couple.
Se consigue de esta manera un "cilindro" puli¬ dor, a través de la generatriz externa de los diferentes grupos de arandelas de lija, cilindro que, por fuerza centrífuga, tiende a adoptar un diámetro máximo, pero que en cualquier punto y en cualquier momento puede reducir dicho diámetro, mediante retracción variable de todas y cada una de las arandelas, merced al montaje excéntrico de las mismas, al objeto de que la superficie operativa del dispositivo pulidor se adecúe a la superfi¬ cie del perfil a pulir, consiguiéndose una perfecta adecuación de formas, en total ausencia de deformaciones ni redondeamientos en los cantos vivos o aristas agudas de dicho perfil.In this way a polishing "cylinder" is achieved, through the external generatrix of the different groups of sandpaper washers, a cylinder that, by centrifugal force, tends to adopt a maximum diameter, but that at any point and in any At this time, this diameter can be reduced, by variable retraction of each and every one of the washers, thanks to the eccentric assembly thereof, so that the operating surface of the polishing device is adapted to the surface of the profile to be polished, achieving a perfect adaptation of forms, in total absence of deformations or rounding in the sharp edges or sharp edges of said profile.
No se considera necesario hacer más extensa esta descripción para que cualquier experto en la materia comprenda el alcance de la invención y las ventajas que de la misma se derivan.
Los materiales, forma, tamaño y disposición de los elementos serán susceptibles de variación, siempre y cuando ello no suponga una alteración a la esencialidad del invento.It is not considered necessary to make this description more extensive so that any person skilled in the art understands the scope of the invention and the advantages derived therefrom. The materials, shape, size and arrangement of the elements will be susceptible to variation, as long as this does not imply an alteration to the essentiality of the invention.
