Description

Bobina con insertos.Coil with inserts.

Bobina con insertos del tipo que comprende una caña, una cavidad por el interior de la citada caña, que atraviesa la bobina de un extremo a otro, unas valonas y unos medios para su fijación en un portabobinas, sitos en la propia valona, y que además incorpora en la citada cavidad al menos un elemento protector, protegiendo la referida caña en al menos una parte de su cavidad interior.Coil with inserts of the type comprising a cane, a cavity inside the aforementioned cane, which crosses the coil from one end to the other, some walloons and some means for its fixing on a bobbin holder, located on the wall itself, and that also incorporates in the said cavity at least one element protector, protecting the aforementioned rod in at least part of its inner cavity

Background of the invention

La presente invención se refiere a una bobina con insertos, que aporta esenciales características de novedad y notables ventajas con respecto a los medios conocidos y utilizados para estos mismos fines en el estado actual de la técnica.The present invention relates to a coil with inserts, which provides essential novelty features and Remarkable advantages over known and used media for these same purposes in the current state of the art.

Las bobinas comúnmente utilizadas tienen el inconveniente de que después de girar sobre el portabobinas durante mucho tiempo, por el rozamiento del portabobinas con la caña, esta última se erosiona y comienza a campanear en el portabobinas desajustando todo el mecanismo, haciendo inútil la función de fijador de los medios de fijación al portabobinas.Commonly used coils have the inconvenient that after turning on the bobbin holder during a long time, by the friction of the bobbin holder with the rod, this last erodes and starts to chime on the bobbin holder unadjusting the entire mechanism, rendering the function of fixing means for fixing to the bobbin holder.

Por otro lado si se utiliza un material más resistente a la erosión en la bobina, ésta a la larga, acaba erosionando al portabobinas.On the other hand if one more material is used Erosion resistant in the coil, it eventually ends eroding the bobbin holder.

Brief description of the requested patent

La presente invención viene a solucionar los graves problemas antes señalados en los antecedentes de la invención.The present invention comes to solve the serious problems noted above in the background of the invention.

De este modo el inventor ha previsto la colocación de un casquillo en la valona al objeto de evitar que la erosión producida en el interior de la caña y en la propia valona desgaste dichos elementos así como produzca daños en la maquinaria utilizada.In this way the inventor has foreseen the placement of a socket in the wall in order to prevent the erosion produced inside the cane and in Walloon itself wear said elements as well as damage the machinery used

Es preciso señalar que de la utilización del referido casquillo se obtienen grandes ventajas. Por un lado se evita la erosión del eje del portabobinas, que está fabricado generalmente en metal, y con ello el de las limaduras que se originan y que se alojan en todos los elementos, provocando un desgaste superior.It should be noted that the use of referred cap are obtained great advantages. On the one hand it prevents erosion of the axis of the bobbin holder, which is manufactured usually in metal, and with it the filings that are originate and that lodge in all the elements, causing a superior wear

Asimismo se evita la erosión en la propia bobina, de tal modo que al no existir erosiones ésta no se balancea (como consecuencia de la erosión) y no se dañan ni la bobina o carrete ni los portabobinas.It also prevents erosion in the coil itself, in such a way that since there are no erosions it does not swing (as consequence of erosion) and the coil or reel is not damaged or the bobbin holders.

Por ello el objeto de la presente invención evita daños tanto en la propia bobina, que no se tiene que tirar, como en la propia máquina portabobinas, que no es erosionada y por tanto no es dañada.Therefore, the object of the present invention avoids damage to the coil itself, which does not have to be thrown, as in the bobbin holder itself, which is not eroded and therefore not It is damaged.

Como es fácil adivinar el coste de un casquillo es infinitamente inferior al coste de una varilla de portabobinas o bien de la bobina misma.How easy it is to guess the cost of a cap is infinitely less than the cost of a bobbin holder rod or Well of the coil itself.

Brief description of the drawings

Con el fin de facilitar la explicación se acompaña a la presente memoria una hoja de dibujos en la que se ha representado un caso práctico de realización, el cual se cita sólo a título de ejemplo, no limitativo del alcance de la presente invención.In order to facilitate the explanation, accompanies here a sheet of drawings in which represented a practical case of realization, which is cited only to Sample title, not limiting the scope of this invention.

En dicha hoja de dibujos:On said sheet of drawings:

- La figura 1 muestra un corte en sección de la referida bobina o carrete.- Figure 1 shows a sectional section of the referred reel or reel.

- La figura 2 es un detalle de la valona, el casquillo y la caña.- Figure 2 is a detail of the Walloon, the Cap and rod.

Concrete realization of the requested patent

En la figura 1 se puede observar la referida bobina, en la que se diferencia una caña (3), con dos valonas (2), una a cada extremo de la misma, y unos medios (4) para la fijación de la bobina a un portabobinas.Figure 1 shows the referred coil, in which a rod (3) is distinguished, with two walloons (2), one at each end thereof, and means (4) for fixing from the coil to a bobbin holder.

El carrete o bobina es atravesado, de valona a valona (2) y por el interior de la mencionada caña (3), por una cavidad (1), donde se insertan dos casquillos (5, 5'), uno por valona, que disponen asimismo dichos casquillos de unas porciones (6), para encajarse en un rebajo (7) existente en la valona (2) de la bobina.The reel or coil is crossed, from Walloon to Walloon (2) and inside the aforementioned rod (3), for a cavity (1), where two bushings (5, 5 ') are inserted, one per Walloon, which also have said caps of portions (6), to fit into a recess (7) existing in the wall (2) of the coil

En la figura 2 se observa el casquillo (5) y su porción (6), completamente extraído del interior de la cavidad (1). Se aprecia también la caña (3), la valona (2), los medios (4) de fijación al portabobinas y el rebajo (7) de la valona.Figure 2 shows the bushing (5) and its portion (6), completely removed from the inside of the cavity (1). The rod (3), the walloon (2), the means (4) of fixing to the bobbin holder and recess (7) of the wall.

De este modo se introduce el casquillo (5) en la cavidad (3) a través del agujero existente en la valona (2), insertando la porción (6) perteneciente al mencionado casquillo (5) (fabricado en un compuesto que contiene acetal o poliamida) dentro del rebajo (7) situado en la valona (2) de la bobina, de tal modo que el referido casquillo (5) quede totalmente insertado en el interior de la bobina.In this way the bushing (5) is inserted into the cavity (3) through the hole in the wall (2), inserting the portion (6) belonging to the aforementioned bushing (5) (made of a compound containing acetal or polyamide) inside of the recess (7) located in the wall (2) of the coil, thereby that the aforementioned bushing (5) is fully inserted in the inside of the coil.

Se coloca, posteriormente, la bobina en un portabobinas (no ilustrado en los dibujos), de tal modo que la varilla o vástago del portabobinas pase por el interior del casquillo (5) y por la cavidad (1), fijándose asimismo dicho portabobinas a los medios (4) de fijación sitos en la valona de la bobina.The coil is then placed in a bobbin holder (not illustrated in the drawings), so that the rod or rod of the bobbin holder passes through the inside of the bushing (5) and through the cavity (1), also fixing said bobbin holder to the fixing means (4) located in the wall of the coil.

Una vez asegurada la bobina en el portabobinas, empieza a girar este último merced a un aparato convencional. En el caso de que después del uso reiterado el mencionado casquillo (5) se erosionase, simplemente se extrae éste y se coloca otro, preservando tanto la bobina como el portabobinas.Once the coil in the bobbin holder is secured, It starts to turn this last thanks to a conventional device. In the case that after repeated use the aforementioned cap (5) erode, simply remove it and place another, preserving both the coil and the bobbin holder.
