La invención se refiere a un tubo portabobinas de material filiforme de cartón cilíndrico que comprende un borde superior, un borde inferior un diámetro interior The invention relates to a bobbin tube of cylindrical cardboard filiform material comprising an upper edge, a lower edge and an inner diameter

10 principal, un diámetro exterior principal y unos medios de retención del tramo inicial del material filiforme próximos al borde inferior. 10, a main outer diameter and means for retaining the initial section of the filiform material near the bottom edge.

Estado de la técnica State of the art

15 Son conocidos los tubos portabobinas de material filiforme para el transporte y suministro de material filiforme, por ejemplo para toda clase de hilos para la industria textil. Estos tubos son substancialmente un cilindro circular. En determinadas aplicaciones el tubo debe tener un diámetro interior constante y 15 Bobbin tubes of filiform material are known for the transport and supply of filiform material, for example for all kinds of threads for the textile industry. These tubes are substantially a circular cylinder. In certain applications the tube must have a constant inside diameter and

20 pasante ya que el tubo debe ser alojado en un eje que lo atraviesa en su totalidad, como por ejemplo en la hilatura continua de poliéster, poliamida o polipropileno. En la presente descripción y reivindicaciones se ha indicado este diámetro interior como el diámetro interior principal, en el sentido que es sobre el que se apoyará el tubo en el eje y que, por lo tanto, debe ser el diámetro interior mínimo presente en 20 as the tube must be housed in a shaft that crosses it in its entirety, such as in the continuous spinning of polyester, polyamide or polypropylene. In the present description and claims, this inner diameter has been indicated as the main inner diameter, in the sense that the tube will rest on the shaft and, therefore, must be the minimum inner diameter present in

25 el interior del tubo. Estos tubos portabobinas comprenden unos medios de retención del tramo inicial del material filiforme, que suele ser un orificio pasante que atraviesa la pared del tubo y que está dispuesto cerca de uno de los extremos y/o una línea o corte de reserva, que se extiende un determinado arco a lo largo de la superficie exterior del tubo paralelamente al borde inferior del mismo. Estos medios 25 the inside of the tube. These bobbin tubes comprise means for retaining the initial section of the filiform material, which is usually a through hole that crosses the tube wall and is arranged near one of the ends and / or a reserve line or cut, which extends a certain arc along the outer surface of the tube parallel to the lower edge thereof. These means

30 de retención fijan el inicio del elemento filiforme que conforma la bobina. En la presente descripción y reivindicaciones se ha denominado borde inferior al borde próximo a estos medios de retención y borde superior al borde opuesto. 30 hold the start of the filiform element that forms the coil. In the present description and claims, the lower edge of the edge next to these retention means and the upper edge of the opposite edge have been designated.

Estos tubos portabobinas son empleados por el fabricante de hilo para bobinar el hilo de manera que luego la bobina puede ser suministrada al cliente. Para ello se apilan una pluralidad de bobinas en un contenedor o una bandeja de transporte. Sin embargo, para apoyar una bobina sobre la siguiente se deben emplear unos These bobbin tubes are used by the thread manufacturer to wind the thread so that the coil can then be supplied to the customer. For this, a plurality of coils are stacked in a container or a transport tray. However, to support one coil over the next one, some

5 separadores que se introducen parcialmente en el interior del tubo inferior y que se apoyan sobre otro separador introducido parcialmente en el tubo superior. Todo ello dificulta y encarece el apilado para el transporte. 5 separators that are partially inserted inside the lower tube and that rest on another separator partially inserted in the upper tube. All of this makes it difficult and expensive to stack for transport.

10 Exposición de la invención 10 Exhibition of the invention

La invención tiene por objeto superar estos inconvenientes. Esta finalidad se consigue mediante un tubo portabobinas del tipo indicado al principio caracterizado porque comprende un rebaje perimetral exterior en uno de los bordes y un rebaje 15 perimetral interior en el otro de los bordes, donde el borde inferior es apto para encajarse en el borde superior de un segundo tubo idéntico al tubo. Efectivamente de esta manera los tubos se apoyan directamente uno sobre el anterior lo que evita la necesidad de los soportes intermedios. En la superficie interior del cilindro se practica un rebaje perimetral interior que, por lo tanto, tiene un diámetro interior The object of the invention is to overcome these drawbacks. This purpose is achieved by means of a bobbin holder tube of the type indicated at the beginning characterized in that it comprises an outer perimeter recess in one of the edges and an inner perimeter recess 15 in the other of the edges, where the lower edge is apt to fit in the upper edge of a second tube identical to the tube. Indeed, in this way the tubes rest directly on the previous one, which avoids the need for intermediate supports. In the inner surface of the cylinder an inner perimeter recess is practiced which, therefore, has an inner diameter

20 mayor que el diámetro interior principal y, por lo tanto, no representa ningún obstáculo para el posterior montaje del tubo en un eje pasante. Por otro lado, dado que el rebaje perimetral interior se hace en una superficie pequeña comparada con la superficie interna total del tubo, la inclusión de este rebaje perimetral interior no afecta a las propiedades generales del tubo. 20 greater than the main inner diameter and, therefore, does not represent any obstacle for the subsequent mounting of the tube on a through shaft. On the other hand, since the interior perimeter recess is made on a small surface compared to the total internal surface of the tube, the inclusion of this interior perimeter recess does not affect the general properties of the tube.

25 Preferentemente el rebaje perimetral exterior está en el borde inferior y el rebaje perimetral interior está en el borde superior. Efectivamente, la superficie exterior del tubo es sobre la que se bobina el material filiforme. Esta superficie exterior tiene una longitud estandarizada, definida por el ancho de la bobina (más los márgenes 25 Preferably the outer perimeter recess is at the lower edge and the inner perimeter recess is at the upper edge. Indeed, the outer surface of the tube is on which the filiform material is wound. This outer surface has a standardized length, defined by the width of the coil (plus the margins

30 necesarios). Por otro lado una pluralidad de maquinaria de bobinado toma como referencia el borde superior del tubo por lo que es ventajoso que el rebaje perimetral exterior no esté en el borde superior sino que esté en el borde inferior. 30 needed). On the other hand, a plurality of winding machinery takes the upper edge of the tube as a reference, so it is advantageous that the outer perimeter recess is not at the upper edge but is at the lower edge.

En este caso, el rebaje perimetral interior está en el borde superior que no afecta en el proceso de bobinado. In this case, the inner perimeter recess is at the upper edge that does not affect the winding process.

Ventajosamente el rebaje perimetral interior tiene su arista exterior redondeada. Advantageously, the inner perimeter recess has its rounded outer edge.

5 Efectivamente, los rebajes perimetrales son preferentemente un escalón formados con dos ángulos rectos, de manera que se forma una pequeña superficie anular y una pared vertical que conforman entre ambas el rebaje perimetral. Sin embargo, al desbobinar el material filiforme, este desbobinado se realiza por el borde superior, por lo que el material filiforme puede entrar en contacto con el borde superior. Para 5 Indeed, the perimeter recesses are preferably a step formed with two right angles, so that a small annular surface and a vertical wall are formed that form the perimeter recess between them. However, when unwinding the filiform material, this unwinding is done by the upper edge, whereby the filiform material can come into contact with the upper edge. For

10 evitar posibles roturas del material filiforme en el caso de que quedase enganchado en el borde superior, es aconsejable redondear la arista exterior del rebaje perimetral interior. Una alternativa particularmente ventajosa es que el rebaje perimetral interior presente un rebordeado en su extremo. 10 to avoid possible breakage of the filiform material in the event that it was caught in the upper edge, it is advisable to round the outer edge of the inner perimeter recess. A particularly advantageous alternative is that the inner perimeter recess has a flange at its end.

15 Otra forma ventajosa de realización de la invención es cuando el rebaje perimetral exterior está en el borde superior y el rebaje perimetral interior está en el borde inferior. En determinados casos esta solución también puede ser de interés. De una forma análoga a como se ha comentado anteriormente, es ventajoso evitar que el material filiforme se pueda romper al rozar con el borde superior, por lo que es Another advantageous embodiment of the invention is when the outer perimeter recess is at the upper edge and the inner perimeter recess is at the lower edge. In certain cases this solution may also be of interest. In a manner analogous to what has been mentioned above, it is advantageous to avoid that the filiform material can break when rubbing with the upper edge, so it is

20 interesante que el rebaje perimetral exterior tenga por lo menos una de sus aristas exteriores redondeadas, y preferentemente ambas. 20 Interestingly, the outer perimeter recess has at least one of its rounded outer edges, and preferably both.

Preferentemente el rebaje perimetral exterior y el rebaje perimetral interior comprenden, cada uno de ellos, una superficie troncocónica, de manera que la 25 superficie troncocónica del rebaje perimetral exterior es apta para apoyarse sobre la superficie troncocónica del rebaje perimetral interior de un segundo tubo idéntico al tubo. Es decir, los rebajes perimetrales ya no están formados simplemente con dos ángulos rectos sino que incluyen una superficie troncocónica. Esta superficie troncocónica permite por ejemplo un guiado y autocentrado de los tubos al ser Preferably, the outer perimeter recess and the inner perimeter recess each comprise a truncated conical surface, so that the truncated conical surface of the outer perimeter recess is able to rest on the truncated conical surface of the inner perimeter recess of a second identical tube to tube. That is, the perimeter recesses are no longer simply formed with two right angles but include a conical surface. This truncated conical surface allows for example a guided and self-centering of the tubes to be

30 apilados unos sobre otros. 30 stacked on each other.

La invención también tiene por objeto una bobina de material filiforme con un tubo portabobinas de acuerdo con la invención, donde preferentemente el material filiforme es poliéster, poliamida o polipropileno. Asimismo es ventajoso el empleo de tubos portabobinas de acuerdo con la invención para la hilatura continua de poliéster, poliamida o polipropileno. A subject of the invention is also a coil of filiform material with a bobbin holder tube according to the invention, where preferably the filiform material is polyester, polyamide or polypropylene. It is also advantageous to use bobbin tubes according to the invention for continuous spinning of polyester, polyamide or polypropylene.
