MANDRIL PARA BOBINASMANDREL FOR COILS
OBJETO DE LA INVENCIONOBJECT OF THE INVENTION
La presente invención se refiere a un mandril para bobinas de gran formato, de papel, plástico, etc. The present invention refers to a mandrel for large format reels of paper, plastic, etc.
ANTECEDENTES DE LA INVENCIONBACKGROUND OF THE INVENTION
En la actualidad, los mandriles para bobinas (canutos o cuerpos tubulares cilíndricos centrales alrededor de los que se arrollan las bobinas), se materializan en cartón. Como las bobinas tienen un tamaño y peso considerable respecto a lo que sería un simple rollo, se requiere una considerable resistencia, y para conseguirla el cartón tiene que ser de tal gramaje que se traduce en un mandril pesado. Currently, mandrels for coils (tubes or central cylindrical tubular bodies around which the coils are wound) are made of cardboard. As the coils have a considerable size and weight compared to what would be a simple roll, considerable resistance is required, and to achieve this the cardboard has to be of such a weight that it results in a heavy mandrel.
Para solucionar este inconveniente, el solicitante es titular de la invención ES2693242 referente a un mandril para bobinas, que tiene una configuración resistente, ligera y reutilizable. Es del tipo que comprenden un cuerpo tubular cilíndrico alrededor del que se arrolla la bobina, en el cual el cuerpo tubular se encuentra materializado en plástico, y comprende unas ventanas aligeradoras en su contorno. To solve this drawback, the applicant is the holder of invention ES2693242 referring to a mandrel for coils, which has a resistant, light and reusable configuration. It is of the type that comprises a cylindrical tubular body around which the coil is wound, in which the tubular body is made of plastic, and includes lightening windows around its contour.
De este modo se consigue la ligereza pretendida, gracias a la mejor resistencia del plástico que permite realizar las ventanas consiguiendo la resistencia adecuada con mayor ligereza, consiguiendo además las ventajas adicionales siguientes: In this way, the intended lightness is achieved, thanks to the better resistance of the plastic that allows the windows to be made, achieving the appropriate resistance with greater lightness, also achieving the following additional advantages:
-es completamente reutilizable, directamente o mediante reciclado del plástico, con una vida útil muy superior al cartón, -it is completely reusable, directly or by recycling plastic, with a useful life much longer than cardboard,
-es inalterable a las condiciones meteorológicas, a diferencia del cartón, que se degrada con la humedad y al ser poroso tiende a absorber humedad deformándose y aumentado de peso, -es fácilmente obtenible por moldeo, -it is unalterable to weather conditions, unlike cardboard, which degrades with humidity and, being porous, tends to absorb moisture, deforming and increasing in weight, -it is easily obtainable by molding,
-es económico y propicia el reciclaje y valorización de otros materiales plásticos de desecho, que pueden ser aprovechados para la fabricación del mandril de la invención. -it is economical and encourages the recycling and recovery of other waste plastic materials, which can be used for the manufacture of the mandrel of the invention.
Sin embargo, en bobinas muy pesadas las últimas vueltas de film pueden salir marcadas por las ventanas, especialmente en bobinas pesadas de uso industrial, lo que puede resultar un inconveniente, tanto estético como debilitador del film. However, in very heavy reels the last turns of film can come out marked by the windows, especially in heavy reels for industrial use, which can be an inconvenience, both aesthetic and weakening the film.
DESCRIPCION DE LA INVENCIONDESCRIPTION OF THE INVENTION
El mandril para bobinas de la invención es del tipo que comprenden un cuerpo tubular cilíndrico materializado en plástico, alrededor del que se arrolla la bobina, donde de acuerdo con la invención, el cuerpo tubular comprende un dentado interior espiral que configura unos nervios interiores que le dan la consistencia, con menor cantidad de material, aligerando el peso y costes, con la ventaja adicional de que puede desmoldearse simplemente desenroscando, sin necesidad de moldes con negativos o elementos de ayuda al desmoldeo que encarezcan el producto The mandrel for coils of the invention is of the type that comprises a cylindrical tubular body made of plastic, around which the coil is wound, where according to the invention, the tubular body comprises an internal spiral toothing that configures internal ribs that They give consistency, with a smaller amount of material, lightening the weight and costs, with the additional advantage that it can be demoulded simply by unscrewing, without the need for molds with negatives or elements to help demold that make the product more expensive.
Presenta, además, las siguientes ventajas: It also has the following advantages:
-es completamente reutilizable directamente o puede ser reciclado 100%. -It is completely reusable directly or can be 100% recycled.
-es inalterable a las condiciones meteorológicas, -it is unalterable to weather conditions,
-propicia el reciclaje y valorización de otros materiales de plásticos de desecho, que pueden ser aprovechados para su fabricación. -promotes the recycling and recovery of other waste plastic materials, which can be used for their manufacture.

DESCRIPCION DE UNA REALIZACION PRACTICA DE LA INVENCIONDESCRIPTION OF A PRACTICAL EMBODIMENT OF THE INVENTION
El mandril (1) para bobinas (2) de la invención es del tipo que comprenden un cuerpo tubular (3) cilíndrico materializado en plástico, alrededor del que se arrolla la bobina, donde de acuerdo con la invención, el cuerpo tubular (3) comprende un dentado (4) interior espiral. The mandrel (1) for coils (2) of the invention is of the type that comprises a cylindrical tubular body (3) made of plastic, around which the coil is wound, where according to the invention, the tubular body (3) It comprises an internal spiral toothing (4).
Se prefiere que el dentado (4) comprenda dos dientes (4a, 4b) paralelos, ya que con menor material se consigue una mayor resistencia It is preferred that the teeth (4) comprise two parallel teeth (4a, 4b), since greater resistance is achieved with less material.
Igualmente, después de las pruebas realizadas, se prefiere que los dientes (4a, 4b) paralelos tengan una anchura y un saliente comprendidos entre el 2 y el 5% del diámetro interior del cuerpo tubular, una separación comprendida entre el 2 y el 5% del diámetro interior del cuerpo tubular y un avance del entre el 15 y el 25% del diámetro interior del cuerpo tubular, por vuelta. Concretamente, para un diámetro exterior del cuerpo tubular de 86,42 milímetros y una longitud de 509 milímetros, su diámetro interior ideal será de 83,10 milímetros, los dientes tendrán una anchura de 2,56 milímetros y saliente de 2,59 milímetros, una separación de 2,49 milímetros, y un avance de 17,15 milímetros, por vuelta. Likewise, after the tests carried out, it is preferred that the parallel teeth (4a, 4b) have a width and a projection between 2 and 5% of the internal diameter of the tubular body, a separation between 2 and 5% of the inner diameter of the tubular body and an advance of between 15 and 25% of the inner diameter of the tubular body, per turn. Specifically, for an outer diameter of the tubular body of 86.42 millimeters and a length of 509 millimeters, its ideal inner diameter will be 83.10 millimeters, the teeth will have a width of 2.56 millimeters and a projection of 2.59 millimeters, a separation of 2.49 millimeters, and an advance of 17.15 millimeters, per turn.
Adicionalmente, el cuerpo tubular (3) puede disponer de unas ventanas (5) aligeradoras. Dichas ventanas (5) se encuentran dispuestas idealmente en el tramo central del cuerpo tubular, ya que soportan menores esfuerzos en esta zona. Additionally, the tubular body (3) may have lightening windows (5). Said windows (5) are ideally located in the central section of the tubular body, since they support less stress in this area.
Descrita suficientemente la naturaleza de la invención, así como la manera de realizarse en la práctica, debe hacerse constar que las disposiciones anteriormente indicadas y representadas en los dibujos adjuntos son susceptibles de modificaciones de detalle en cuanto no alteren el principio fundamental. Once the nature of the invention has been sufficiently described, as well as the way it is carried out in practice, it should be noted that the provisions previously indicated and represented in the attached drawings are susceptible to detailed modifications as long as they do not alter the fundamental principle.
