El objeto de la presente invención recae, por un lado, en una bobina de hilo, en concreto hilo de fibras textiles naturales, sintéticas o artificiales, en la que la torsión de dicho hilo enrollado en la bobina es tal que al desenrollarse a “de filé” en una dirección la torsión del hilo es constante y es esencialmente cero tpm (torsiones por metro), mientras que al desenrollarse en la dirección opuesto dicha torsión es variable a lo largo de toda la bobina y equivale 2/(DI * TT) donde DI es el diámetro instantáneo de enrollado/desenrollado de la bobina en metros.

CAMPO DE APLICACIÓN DE LA INVENCIÓN FIELD OF APPLICATION OF THE INVENTION
El campo de aplicación de la presente invención se enmarca en el sector de la industria textil de cualquier tipo de hilos, especialmente hilos delicados como los hilos de fibra de vidrio. The field of application of the present invention falls within the sector of the textile industry of any type of threads, especially delicate threads such as fiberglass threads.
ANTECEDENTES DE LA INVENCIÓN BACKGROUND OF THE INVENTION
En el sector textil, son conocidas las máquinas retorcedoras que sobre un hilo o haz de fibras sin torsión (en adelante hilo sin torsión o con torsión cero) aplican unas determinadas vueltas o torsiones por cada metro de hilo o fibra textil (en adelante hilo con torsión) y recogen el hilo con torsión en una bobina. In the textile sector, twisting machines are known that apply certain turns or twists to a yarn or bundle of fibers without twist (hereinafter yarn without twist or with zero twist) for each meter of yarn or textile fiber (hereinafter yarn with zero twist). twist) and take up the thread with twist on a bobbin.
Dicha bobina de recogida de hilo puede tener forma cilindrica, cónica, doble cónica u otras sobre un soporte que puede ser un tubo de cartón o un envase de bobina formato carrete o botella u otros. En definitiva, el formato de la bobina final no es limitativo y depende del proceso posterior con el que se utilizara la bobina con hilo con torsión). Said thread collection spool can have a cylindrical, conical, double conical or other shape on a support that can be a cardboard tube or a reel or bottle format spool container or others. In short, the format of the final coil is not limiting and depends on the subsequent process with which the coil with twisted wire was used).
Hay diversas tecnologías de máquinas retorcedoras textiles que se diferencian por tener distinto principio de funcionamiento, aunque la finalidad de torcer y bobinar un hilo es la misma, estas generalmente son: There are various technologies of textile twisting machines that differ in that they have different operating principles, although the purpose of twisting and winding a thread is the same, these are generally:
- tecnología de torcido de anillo - cursor (máquinas de anillos), - ring twisting technology - slider (ring machines),
- tecnología de torcido de doble torsión (2x1 ), - double twist twisting technology (2x1 ),
- tecnología de torcido del tipo molino, - mill-type twisting technology,
- tecnología de torcido del tipo cableadora o cabling, - twisting technology of the stranding or cabling type,
- otras tecnologías derivadas de estas... - other technologies derived from these...
Además de las fibras naturales, existen las fibras sintéticas y las fibras artificiales y continuamente se desarrollan nuevas fibras o filamentos que mejoran las propiedades de la fibra dependiendo del fin a la que se destina. Dicha diversidad de nuevas exigencias de propiedades de las fibras de hilo o tejidos, implican también aplicar determinadas características mecánicas sobre el hilo como son la torsión. In addition to natural fibers, there are synthetic fibers and artificial fibers and new fibers or filaments are continually being developed that improve the properties of the fiber depending on the purpose for which it is intended. Said diversity of new requirements for properties of yarn fibers or fabrics also imply applying certain mechanical characteristics to the yarn, such as torsion.
La torsión aplicada en un hilo o haz de fibras se define como las vueltas de hilo sobre su propio eje que se le aplican a 1 m de dicho hilo. La unidad de torsión en el sistema métrico es vueltas/metro o tpm (torsiones por metro), aunque en el sistema anglosajón se usa también vueltas/pulgada o TPI u otras. The twist applied to a yarn or fiber bundle is defined as the turns of yarn on its own axis that are applied to 1 m of said yarn. The unit of torque in the metric system is turns/meter or tpm (twists per meter), although in the Anglo-Saxon system turns/inch or TPI or others are also used.
De manera usual en el estado de la técnica actual, el valor de la torsión es una característica que aporta valor al hilo a través de aportar unas propiedades de resistencia a la rotura, cierto alongamiento, sentido de torsión S/Z, etc., que son deseadas generalmente para obtener un fin concreto en un posterior tejido, construcción de una cuerda u otros. In a usual way in the current state of the art, the value of the twist is a characteristic that adds value to the yarn by providing properties of resistance to breakage, a certain elongation, sense of twist S/Z, etc., which they are generally desired to obtain a specific purpose in subsequent weaving, rope construction or others.
En el caso de máquinas retorcedoras de anillos cabe recordar que se denomina torsión “S” cuando el huso o bobina donde se está hilando o torciendo gira en sentido contrario a las manecillas del reloj, y se denomina torsión “Z” cuando el huso en donde se está hilando o torciendo gira en sentido a las manecillas del reloj. In the case of ring twisting machines, it should be remembered that it is called "S" torsion when the spindle or bobbin where it is spinning or twisting rotates counterclockwise, and it is called "Z" torsion when the spindle where being spun or twisted rotates clockwise.
En el caso de máquinas del tipo de doble torsión cabe recordar que se denomina torsión “S” cuando el plato giratorio de los medios de torsión de la maquina gira en sentido contrario a las manecillas del reloj, y se denomina torsión “Z” cuando el plato giratorio de los medios de torsión de la maquina gira en sentido a las manecillas del reloj. In the case of machines of the double torsion type, it should be remembered that it is called "S" torsion when the turntable of the torsion means of the machine rotates counterclockwise, and it is called "Z" torsion when the Turntable of the twisting means of the machine rotates clockwise.
No se entra en detalle sobre las definiciones de ciertos parámetros como resistencia a la rotura, alongamiento, sentido de torsión S/Z y otros muchos, dado que ya son conocidos en el sector textil en general. It does not go into detail about the definitions of certain parameters such as resistance to breakage, elongation, sense of torsion S / Z and many others, since they are already known in the textile sector in general.
Aun así, y como aclaración, un mismo hilo torcido en un sentido de torsión u otro (sentido S o sentido Z) también puede alterar las características para obtener un fin concreto en un posterior tejido, construcción de una cuerda u otros. Even so, and as a clarification, the same thread twisted in one direction of twist or another (direction S or direction Z) can also alter the characteristics to obtain a specific purpose in a subsequent fabric, construction of a rope or others.
Por ejemplo, no tiene nada que ver en cuanto a características mecánicas un hilo cableado a 2 cabos con una estructura de primera torsión de 10Otpm en sentido S y segunda torsión de 80 tpm en sentido Z, que el mismo hilo cableado a dos cabos con una estructura de primera torsión de 100tpm en sentido S y segunda torsión de 80 tpm también en sentido S. For example, in terms of mechanical characteristics, a 2-strand cabled wire with a structure with a first twist of 10Otpm in the S direction and a second 80 tpm twist in the Z direction has nothing to do with what the same two-strand cabled wire with a structure with a first twist of 100 tpm in the S direction and a second twist of 80 tpm also in the S direction.
Al mismo tiempo, un mismo hilo torcido en un grado de torsión u otro también cambia las propiedades del mismo mecánicas, con lo que, en función de la finalidad a la que este hilo va a ser destinado y las propiedades que se necesiten, se le aplicará un grado de torsión determinado y un sentido de torsión S/Z también determinado. At the same time, the same twisted yarn in one degree of twist or another also changes its mechanical properties, so that, depending on the purpose for which this yarn is going to be used and the properties that are needed, it is will apply a certain degree of twist and a certain sense of twist S/Z.
En cuanto a la estructura del hilo con torsión, esta puede ser un haz de fibras continuas sintéticas o artificiales que se agrupan en paralelo (grado de torsión cero) formando un hilo sin torcer y que se pliega en bobinas sobre un soporte de tubo mayoritariamente de cartón o plástico. As for the structure of the twisted yarn, this can be a bundle of continuous synthetic or artificial fibers that are grouped in parallel (zero twist degree) forming an untwisted yarn and that is folded in coils on a tube support, mostly of cardboard or plastic.
Ciertos productos como por ejemplo algunos tejidos textiles, necesitan fabricarse a partir de hilos torcidos en un grado de torsión determinado. Certain products, such as some textile fabrics, need to be manufactured from yarns twisted to a certain degree of twist.
Múltiples bobinas de hilo torcido se colocan generalmente en unas estructuras estáticas, denominadas filetas, que soportan las bobinas con hilo por el interior del tubo y facilitan/guían el desplegado de los hilos de las bobinas que están estáticas en la fileta hacia el telar. Dicho tipo de desplegado se hace con la bobina estática y tirando el hilo en dirección al eje de la bobina y se denomina “de filé “en el que ya es conocido que este tipo de desplegado hace variar la estructura del hilo torcido, aunque esta variación no supone un cambio sustancial sobre la estructura del hilo respecto cuando está torcido en la bobina comparado con cuando está desplegado y es perfectamente aceptado en un gran porcentaje de procesos y productos textiles. Multiple bobbins of twisted yarn are generally placed in static structures, called creels, which support the bobbins with yarn inside the tube and facilitate/guide the unfolding of the yarns from the bobbins that are static on the creel towards the loom. Said type of unfolding is done with the bobbin static and pulling the thread in the direction of the axis of the bobbin and is called "filé" in which it is already known that this type of unfolding varies the structure of the twisted thread, although this variation it does not imply a substantial change in the structure of the yarn with respect to when it is twisted in the coil compared to when it is unfolded and it is perfectly accepted in a large percentage of textile processes and products.
También, si el mismo tipo de desplegado a de filé se usa en bobinas que tienen hilo sin torsión, el efecto del desplegado modifica la estructura del hilo en cuanto a torsiones, ya que en el desplegado a de filé se adquieren ciertas torsiones en un sentido determinado, alimentándose los hilos al siguiente proceso no en condiciones de hilo a cero torsiones. Los sectores del textil que usan este tipo de bobinas y desplegado generalmente también aceptan sin más problemas este efecto. Also, if the same type of unfolding a de filé is used in packages that have untwisted yarn, the effect of the unfolding modifies the structure of the yarn in terms of twists, since in the unfolding a de filé certain twists are acquired in one direction. determined, the yarns being fed to the next process not in zero-twist yarn conditions. The textile sectors that use this type of reels and unfolding generally also accept this effect without further problems.
Según la técnica actual, cualquier proceso en el que una fileta alberga al menos una bobina con las fibras paralelas (torsión cero) y que las guía hacia la máquina o proceso posterior, y, al mismo tiempo se necesita también que el hilo desplegado sea también de torsión cero o sin torsión, el desplegado de las bobinas de la fileta se efectúa tirando del hilo por el lateral de la bobina (perpendicular al eje) y haciendo girar la bobina a través de crear una tensión del propio hilo al desplegarse. According to the current technique, any process in which a creel houses at least one bobbin with parallel fibers (zero twist) and guides them towards the subsequent machine or process, and, at the same time, also requires that the unfolded yarn is also zero torsion or no torsion, the unfolding of the coils of the creel is carried out by pulling the thread from the side of the coil (perpendicular to the axis) and turning the coil by creating a tension of the thread itself when unfolding.
Este tipo de desplegado se denomina “de roulé “y las filetas necesarias para este tipo de desplegado son mucho más complicadas porque las bobinas deben girar y generar toda la misma tensión e implican que las tensiones de los hilos generadas por el giro de las bobinas en su desplegado hacen que se deban compensar con alimentadores de hilos adicionales entre la fileta y la maquina posterior como podría ser un telar u otra máquina. This type of unfolding is called “de roulé” and the creels necessary for this type of unfolding are much more complicated because the coils must rotate and generate all the same tension and imply that the tensions of the yarns generated by the rotation of the coils in its unfolding makes it necessary to compensate with additional thread feeders between the creel and the subsequent machine, such as a loom or another machine.
Al mismo tiempo las velocidades de desplegado son más bajas y limitan la productividad del proceso ya que las inercias generadas por el movimiento de giro de las bobinas y las tensiones de los hilos son muy grandes cuando las bobinas están llenas de hilo. At the same time, the unfolding speeds are lower and limit the productivity of the process since the inertia generated by the turning movement of the reels and the tensions of the threads are very large when the reels are full of thread.
Por todas estas problemáticas sería interesante disponer de una bobina de un hilo al desplegarse el hilo a “de filé” en una primera dirección, el valor de la torsión del hilo una vez desplegado a de filé sea constante a lo largo de toda la bobina y equivalga esencialmente a 0 tpm. Due to all these problems, it would be interesting to have a one-wire reel when the thread is unfolded "de filé" in a first direction, the value of the twist of the thread once deployed to de filé is constant throughout the entire reel and equals essentially 0 tpm.
EXPLICACIÓN DE LA INVENCIÓN EXPLANATION OF THE INVENTION
La bobina de hilo de fibras textiles naturales, sintéticas o artificiales, el proceso de torcido de hilo y la máquina de torcido de hilo que la invención propone se configuran como una solución idónea a la problemática anteriormente descrita, estando los detalles caracterizadores que lo hacen posible y que las distinguen convenientemente recogidos en las reivindicaciones finales que acompañan a la presente descripción. The bobbin of natural, synthetic or artificial textile fiber yarn, the yarn twisting process and the yarn twisting machine that the invention proposes are configured as an ideal solution to the problem described above, with the characterizing details that make it possible and that they are conveniently distinguished in the final claims that accompany this description.
Concretamente, lo que la invención propone, fruto de la necesidad tecnológica anteriormente mencionada y como se ha apuntado anteriormente, es, por un lado, una bobina de hilo, en concreto hilo de fibras textiles naturales, sintéticas o artificiales, en la que la torsión de dicho hilo enrollado en la bobina es tal que al desenrollarse el hilo a “de filé” en una primera dirección, la torsión del hilo es constante y es esencialmente cero tpm (torsiones por metro), mientras que al desenrollarse a de filé en la dirección opuesta dicha torsión es variable a lo largo de toda la bobina y equivale a: β’ (tpm) = 2/(DI * TT) donde el DI es el diámetro instantáneo de enrollado o desenrollado o en otras palabras el diámetro en metros (m) de la bobina en el instante que se está bobinando o desbobinando. Specifically, what the invention proposes, as a result of the aforementioned technological need and as noted above, is, on the one hand, a coil of thread, specifically natural, synthetic or artificial textile fiber thread, in which the torsion of said yarn wound on the bobbin is such that when the yarn is unwound a de filé in a first direction, the twist of the yarn is constant and is essentially zero tpm (twists per meter), while when unwinding a de filé in the opposite direction said torsion is variable throughout the coil and is equivalent to: β' (tpm) = 2/(DI * TT ) where the DI is the instantaneous winding or unwinding diameter or in other words the diameter in meters (m) of the reel at the instant it is being wound or unwound.
Más específicamente, la invención se refiere a una bobina que contiene hilo con torsión en que, el valor de la torsión del hilo plegado (que señalaremos como alfa) y que, como se ha dicho es variable y está asociada al diámetro instantáneo de enrolladlo/desenrollado (DI) de la propia bobina cumple la siguiente expresión: alfa (tpm) = 1/(DI * TT) de tal manera que, al desplegarse el hilo a “de filé” en una primera dirección, el valor de la torsión del hilo una vez desplegado a “de filé” (que en este caso indicaremos como P) es constante a lo largo de toda la bobina y tiende a 0, β (tpm) = 0 y de tal manera que al desplegarse el hilo a “de filé” en una segunda dirección contraria a la primera dirección, el valor de la torsión del hilo una vez desplegado a “de filé” (β’) es variable a lo largo de todo el desplegado y equivale a: β’ (tpm) = 2/(DI(m) * TT) More specifically, the invention relates to a reel containing twisted yarn in which the value of the twist of the folded yarn (which we will indicate as alpha) and which, as has been said, is variable and is associated with the instantaneous diameter of winding/ unwinding (DI) of the reel itself complies with the following expression: alpha (tpm) = 1/(DI * TT ) in such a way that, when the thread unfolds to “de filé” in a first direction, the value of the torsion of the thread once unfolded to "de fille" (which in this case we will indicate as P) is constant throughout the entire coil and tends to 0, β (tpm) = 0 and in such a way that when the thread is unfolded to "de fille” in a second direction contrary to the first direction, the twist value of the thread once unfolded to “de fille” (β') is variable throughout the unfolding and is equal to: β' (tpm) = 2/(DI(m) * TT )
También, preferentemente, se destaca que el formato de la bobina, que puede ser cilindrica, cónica doble cónica, con platos (carrete), etc., no se ve afectado por la caracterización de la bobina siempre que cumpla el requisito de valor de torsión descrito. Also, preferably, it is emphasized that the format of the coil, which can be cylindrical, conical, double conical, with plates (spool), etc., is not It is affected by the characterization of the coil as long as it meets the described torque value requirement.
Para obtener hilo a torsión 0 tpm simplemente hay que desplegar el hilo de la bobina a “de filé” en la dirección correcta tal que sea la torsión generada por el desplegado compense la torsión del hilo plegado. Para facilitar la identificación correcta del desplegado se pueden utilizar marcas en la bobina. To obtain yarn with a twist of 0 tpm, you simply have to unfold the yarn from the “de fille” reel in the correct direction such that the twist generated by the unfolding compensates for the twist of the folded yarn. To facilitate the correct identification of the unfolding, markings on the roll can be used.
Es también objeto de la invención el proceso de torcido de hilo que permite generar una bobina como la descrita anteriormente. Another object of the invention is the thread twisting process that allows a bobbin like the one described above to be generated.
El proceso de torcido de hilo comprende esencialmente las siguientes etapas. The yarn twisting process essentially comprises the following steps.
• Torcido del hilo mediante unos medios de torsión que aplican una torsión asociada al diámetro instantáneo de enrolladlo/desenrollado de la propia bobina • Twisting of the thread by means of torsion means that apply a torque associated with the instantaneous winding/unwinding diameter of the reel itself.
• Plegado del hilo en una bobina de recogida tal manera que el valor de la torsión del hilo plegado (α) a lo largo de toda la bobina de recogida es variable y está asociada al diámetro instantáneo de enrolladlo/desenrollado (DI) de la propia bobina y equivale a: α (tpm) = 1/ (DI * TT) • Folding of the yarn in a take-up spool such that the value of the twist of the folded yarn (α) along the entire take-up spool is variable and is associated with the instant winding/unwinding diameter (DI) of the spool itself. coil and is equivalent to: α (tpm) = 1/ (DI * TT )

REALIZACIÓN PREFERENTE DE LA INVENCIÓN PREFERRED EMBODIMENT OF THE INVENTION
A la vista de las mencionadas figuras, y de acuerdo con la numeración adoptada, se puede observar en ellas diversos ejemplos de realización no limitativa de la invención, la cual comprende lo que se describe en detalle a continuación. In view of the aforementioned figures, and according to the numbering adopted, various examples of non-limiting embodiments of the invention can be observed, which includes what is described in detail below.
Así, tal como se observa en dichas figuras, una bobina primaria o bobina de entrega (2), con un hilo (H) multifilamento, por ejemplo, de poliamida de título 1 10 Tex y sin torsión, se procesa en una máquina (100) retorcedora sobre un envase que será el soporte de la bobina (1 ) de la presente invención. Thus, as can be seen in said figures, a primary reel or delivery reel (2), with a multifilament thread (H), for example, polyamide with a 1 10 Tex title and without twist, is processed in a machine (100 ) twister on a container that will support the coil (1) of the present invention.
El hecho de utilizar la palabra procesar implica que la máquina (100) retorcedora se alimenta del hilo (H) primario que no tiene torsión, torsiona el hilo en un cierto grado de torsión y sentido de giro (S o Z) mediante unos medios de torsión y lo bobina ya torcido sobre el soporte que, por ejemplo, es un tubo de cartón de diámetro exterior d= 75mm, y en que el diámetro máximo (D) de la bobina (1 ) es de 200mm. The fact of using the word process implies that the twisting machine (100) is fed with the primary yarn (H) that has no twist, twists the yarn in a certain degree of twist and direction of rotation (S or Z) by means of twisting and coiling it already twisted on the support which, for example, is a cardboard tube with an outer diameter d= 75mm, and in which the maximum diameter (D) of the coil (1) is 200mm.
La característica principal de la máquina (100) retorcedora es que el valor de la torsión a aplicar en la maquina Ω) por los medios de torsión es tal que el valor de la torsión del hilo plegado (α) es variable y está asociada al diámetro instantáneo de enrolladlo/desenrollado (DI) de la propia bobina de recogida (1 ) y equivale a: α (tpm) = 1/(DI(m) * TT) The main characteristic of the twisting machine (100) is that the value of the twist to be applied in the machine Ω) by the twisting means is such that the value of the twist of the folded wire (α) is variable and is associated with the diameter instant winding/unwinding (DI) of the reel itself (1) and is equivalent to: α (tpm) = 1/(DI(m) * TT )
Por ejemplo, al empezar el ciclo de torcido y bobinado, se empieza bobinando el hilo ya torcido sobre el tubo de cartón de 75mm. En este punto la torsión que debe tener el hilo plegado es de: alfa 75 = 1/ (0,075*3,1416) = 4,24 tpm (torsiones por metro) For example, at the beginning of the twisting and winding cycle, you begin by winding the already twisted thread on the 75mm cardboard tube. At this point, the twist that the folded thread must have is: alpha 75 = 1/ (0.075*3.1416) = 4.24 tpm (twists per meter)
En cambio, al acabar la bobina de recogida (1 ), cuando esta llegue al diámetro máximo de 200mm, la torsión que debe tener el hilo plegado es de: alfa 200 = 1/ (0,2*3,1416) = 1 ,59 tpm (torsiones por metro) On the other hand, at the end of the take-up reel (1), when it reaches the maximum diameter of 200mm, the twist that the folded wire must have is: alpha 200 = 1/ (0.2*3.1416) = 1, 59 tpm (twists per meter)
A medida que durante el proceso de torcido y bobinado la bobina de recogida (1 ) vaya adquiriendo mayor diámetro, la torsión que debe tener el hilo plegado será distinta y se encontrará dentro de valores de alfa75 y alfa200. As the take-up spool (1) acquires a larger diameter during the twisting and winding process, the twist that the folded wire must have will be different and will be within the values of alpha75 and alpha200.
En el caso que el formato de la bobina de hilo torcido sea cónico o doble cónico u otro, se procede de la misma manera. Es decir, se deberá aplicar una torsión (Ω) en los medios de torsión de la maquina tal que el valor de la torsión del hilo plegado (α) sea variable y esté asociada al diámetro instantáneo de enrolladlo/desenrollado (DI) de la propia bobina de recogida (1 ) y equivalga a: α (tpm) = 1/ (DI * TT) In the event that the format of the twisted wire reel is conical or double conical or another, the procedure is the same. That is, a torque (Ω) must be applied to the twisting means of the machine such that the twist value of the folded wire (α) is variable and is associated with the instantaneous winding/unwinding diameter (DI) of the wire itself. pickup coil (1 ) and equals: α (tpm) = 1/ (DI * TT )
Ello implica que la máquina (100) retorcedora, sea cual sea la tecnología utilizada, deberá conocer durante todo el proceso de torcido el diámetro instantáneo (DI) de la bobina de recogida (1 ) de hilo torcido puesto que este diámetro instantáneo (DI) es cambiante a lo largo del proceso de bobinado. This implies that the twisting machine (100), whatever the technology used, must know the diameter throughout the twisting process. diameter (DI) of the twisted wire take-up reel (1) since this instantaneous diameter (DI) changes throughout the winding process.
Atendiendo a las figuras número 1 -A y 1 -B, se puede a preciar dos ejemplos de la bobina (1 ) objeto de la invención con respectivos tipos de desenrollado del hilo, en que se observa cómo se cumple que el valor de la torsión del hilo plegado (α) a lo largo de toda la bobina (1 ) es tal que al desplegarse el hilo a “de filé” en una primera dirección (S) (figura 1 -A), el valor de la torsión del hilo una vez desplegado a “de filé” (P) es constante a lo largo de toda la bobina y tiende a 0, β (tpm) = 0 y tal que, al desplegarse el hilo a “de filé” en una segunda dirección (Z) (figura 1 -B), contraria a la primera dirección (S), el valor de la torsión del hilo una vez desplegado a de filé (β’) es variable a lo largo de todo el desplegado y equivale a: β’ (tpm) = 2/ (DI * Pl) Based on figures number 1 -A and 1 -B, two examples of the coil (1) object of the invention can be seen with respective types of unwinding of the thread, in which it is observed how it is fulfilled that the value of the torsion of the folded thread (α) along the entire bobbin (1) is such that when the thread unfolds to “de filé” in a first direction (S) (figure 1 -A), the value of the twist of the thread a Once unfolded to “de fille” (P) is constant throughout the entire bobbin and tends to 0, β (tpm) = 0 and such that, when the yarn is unfolded to “de fille” in a second direction (Z) (figure 1 -B), contrary to the first direction (S), the twist value of the thread once unfolded to de filé (β') is variable throughout the unfolding and is equivalent to: β' (tpm ) = 2/ (DI * Pl)
Atendiendo a la figura 2 se observa una representación esquemática de un primer ejemplo de la máquina (100), en concreto una máquina de anillos con una bobina de entrega (2) de hilo a “roulé”. Referring to figure 2, a schematic representation of a first example of the machine (100) is observed, specifically a ring machine with a delivery reel (2) of thread to "roulé".
En este caso, el hilo (H) que sale de la bobina de entrega (2) de hilo que no tiene torsión (valor de torsión al hilo previo a los medios de torsión (λ) = 0), es decir que el desplegado no añade torsión. El hilo desplegado de la bobina (2) pasa por unos medios de torsión, en este caso que comprenden unos medios de guiado (200), un conjunto anillo-cursor y unos medios de giro (300) de la bobina de recogida (1 ), que aplican a la maquina un valor de torsión al hilo (Ω) cumpliendo la siguiente fórmula: In this case, the yarn (H) coming out of the yarn delivery spool (2) that has no twist (twist value to the yarn prior to the twist means (λ) = 0), that is, the unfolding does not add torque. The thread unfolded from the reel (2) passes through twisting means, in this case comprising guiding means (200), a ring-cursor assembly and turning means (300) of the pick-up reel (1) , which apply to the machine a value of twist to the thread (Ω) complying with the following formula:
(Ω) tpm=(2/(DI1 ) *3,1416), donde: rpm de la bobina (1 ) = (Ω) tpm * velocidad lineal del hilo (H). (Ω) tpm=(2/(DI1 ) *3.1416), where: spool rpm (1 ) = (Ω) tpm * linear wire speed (H).
Atendiendo a las figuras número 3-A y 3-B se observa otro ejemplo de la máquina (100), en concreto una máquina de anillos con una bobina de entrega (2) de hilo que despliega a “de filé”. La máquina comprende una bobina de entrega (2) de hilo (H) a torsión 0, unos medios de torsión que aplican al hilo (H) una torsión al hilo (Ω), una bobina de recogida (1 ) de hilo (H) con un valor de la torsión del hilo plegado y ya torcido (α), unos medios para conocer el diámetro instantáneo (DI2) de la bobina de entrega (2), unos medios para conocer el diámetro instantáneo (DI) de la bobina de recogida (1 ) y unos medios para modificar la torsión (Ω) aplicada al hilo en los medios de torsión. Referring to figures 3-A and 3-B, another example of the machine (100) can be seen, specifically a ring machine with a thread delivery reel (2) that unfolds "de filé". The machine comprises a delivery reel (2) of thread (H) at 0 torsion, torsion means that apply a torsion to the thread (Ω) to the thread (H), a collection reel (1) of thread (H) with a twist value of the folded and already twisted yarn (α), means for knowing the instantaneous diameter (DI2) of the delivery reel (2), means for knowing the instantaneous diameter (DI) of the pick-up reel (1) and means for modifying the twist (Ω) applied to the wire in the twisting means.
En este caso el hilo que sale de la bobina de entrega (1 ) de hilo tiene una torsión (λ) como consecuencia del desenrollado, el valor de torsión al hilo previo a los medios de torsión (λ) depende del tipo de la dirección del deplegado (S o Z). In this case the thread coming out of the thread delivery spool (1) has a twist (λ) as a consequence of unwinding, the value of twist to the thread prior to the means of twisting (λ) depends on the type of direction of the thread. unfolded (S or Z).
Tal y como se observa en la figura 3-A, el desplegado de la bobina (2) provoca que el hilo desplegado tenga una torsión en sentido Z con un valor de torsión previo a los medios de torsión (λ) que equivale a: As can be seen in figure 3-A, the unfolding of the bobbin (2) causes the unfolded yarn to have a twist in the Z direction with a value of twist prior to the means of twist (λ) that is equal to:
(λ) = (1/(DI2) *3,1416), (λ) = (1/(DI2) *3.1416),
En este caso, cuando los medios de torsión aplican una torsión (Ω) en dirección Z, la torsión (Ω) debe equivaler a: Ω (tpm) = (2/(DI1 ) *3,1416) - (1/(DI2) *3,1416) con el objetivo de que el valor de la torsión del hilo plegado (α) a Io largo de toda la bobina de recogida (1 ) sea variable y esté asociada al diámetro instantáneo de enrolladlo/desenrollado (DI) de la propia bobina de recogida (1 ) y equivale a: α (tpm) = 1/(DI(m) * TT) In this case, when the torque means apply a torque (Ω) in the Z direction, the torque (Ω) must equal: Ω (tpm) = (2/(DI1 ) *3.1416) - (1/(DI2) *3.1416) with the aim that the value of the twist of the folded wire (α) along the entire take-up reel (1) is variable and is associated with the instant winding/unwinding diameter (DI) of the take-up reel itself (1) and is equal to: α (tpm) = 1/(DI(m) * TT )
En cambio, cuando en este caso los medios de torsión aplican una torsión (Ω) en dirección S, la torsión (Ω) debe equivaler a: Ω (tpm) = (2/(DI1 ) *3,1416) + (1/(DI2) *3,1416) donde: rpm de la bobina (1 ) = Ω (tpm)* velocidad lineal (m/min). con el objetivo de que el valor de la torsión del hilo plegado (α) a lo largo de toda la bobina de recogida (1 ) sea variable y esté asociada al diámetro instantáneo de enrolladlo/desenrollado (DI) de la propia bobina de recogida (1 ) y equivale a: α (tpm) = 1/(DI(m) * TT) On the other hand, when in this case the torsion means apply a torsion (Ω) in the S direction, the torsion (Ω) must be equal to: Ω (tpm) = (2/(DI1 ) *3.1416) + (1/ (DI2) *3.1416) where: coil rpm (1 ) = Ω (tpm)* linear speed (m/min). with the aim that the value of the twist of the folded wire (α) along the entire collection reel (1) is variable and is associated with the instantaneous winding/unwinding diameter (DI) of the collection reel itself ( 1 ) and is equivalent to: α (tpm) = 1/(DI(m) * TT )
Tal y como se observa en la figura 3-B, el desplegado provoca que el hilo desplegado tenga una torsión en sentido S con un valor de torsión previo a los medios de torsión (λ) que equivale a: As can be seen in figure 3-B, unfolding causes the unfolded yarn to have a twist in the S direction with a value of twist prior to the means of twist (λ) that is equal to:
(λ) = (1/(DI2) *3,1416), (λ) = (1/(DI2) *3.1416),
En este caso, cuando los medios de torsión aplican una torsión (Ω) en dirección Z, la torsión (Ω) debe equivaler a: Ω (tpm) = (2/(DI1 ) *3,1416) + (1/(DI2) *3,1416) donde: rpm de la bobina (1 ) = Ω (tpm)* velocidad lineal. con el objetivo de que el valor de la torsión del hilo plegado (α) a lo largo de toda la bobina de recogida (1 ) sea variable y esté asociada al diámetro instantáneo de enrolladlo/desenrollado (DI) de la propia bobina de recogida (1 ) y equivale a: α (tpm) = 1/(DI(m) * TT) In this case, when the torque means apply a torque (Ω) in the Z direction, the torque (Ω) must equal: Ω (tpm) = (2/(DI1 ) *3.1416) + (1/(DI2 ) *3.1416) where: coil rpm (1 ) = Ω (tpm)* linear speed. with the aim that the value of the twist of the folded wire (α) along the entire collection reel (1) is variable and is associated with the instantaneous winding/unwinding diameter (DI) of the collection reel itself ( 1 ) and is equivalent to: α (tpm) = 1/(DI(m) * TT )
En cambio, cuando en este caso los medios de torsión aplican una torsión (Ω) en dirección S, la torsión (Ω) debe equivaler a: Ω (tpm) = (2/(D 11 ) *3, 1416) - (1/(DI2) *3,1416) On the other hand, when in this case the torsion means apply a torsion (Ω) in the S direction, the torsion (Ω) must be equal to: Ω (tpm) = (2/(D 11 ) *3, 1416) - (1 /(DI2) *3.1416)
Finalmente, atendiendo a las figuras número 4-A y 4-B, se observa otro ejemplo de la máquina (100), en concreto una máquina 2x1 con una bobina de entrega (2) de hilo a “de filé”. La máquina comprende una bobina de entrega (2) de hilo (H) a torsión 0, unos medios de torsión que aplican al hilo (H) una torsión al hilo (Ω), una bobina de recogida (1 ) de hilo (H) con un valor de la torsión del hilo plegado (α), unos medios para conocer el diámetro instantáneo (DI2) de la bobina de entrega (2), unos medios para conocer el diámetro instantáneo (DI) de la bobina de recogida (1 ) y unos medios para modificar la torsión (Ω) aplicada al hilo en los medios de torsión. Finally, according to figures 4-A and 4-B, another example of the machine (100) can be seen, specifically a 2x1 machine with a delivery reel (2) of thread to "de filé". The machine comprises a delivery reel (2) of thread (H) at 0 torsion, torsion means that apply a torsion to the thread (Ω) to the thread (H), a collection reel (1) of thread (H) with a value of the twist of the folded wire (α), means to know the instantaneous diameter (DI2) of the delivery coil (2), means to know the instantaneous diameter (DI) of the collection coil (1) and means for modifying the twist (Ω) applied to the yarn in the twisting means.
En este caso, el hilo (H) que sale de la bobina de entrega (2) de hilo tiene torsión como consecuencia del desplegado. El hilo desplegado pasa por unos medios de torsión, en este caso que comprenden un plato giratorio, unos medios de guiado (200), y unos medios de giro (300) del plato giratorio de los medios de torsión. In this case, the yarn H coming out of the yarn delivery spool 2 has twist as a result of unfolding. The unfolded thread passes through twisting means, in this case comprising a turntable, guide means (200), and turning means (300) of the turntable of the twisting means.
Tal y como se observa en la figura 4-A, el desplegado provoca que el hilo desplegado de la bobina de entrega (2) tenga una torsión en sentido Z con un valor de torsión previo a los medios de torsión (λ) que equivale a: As can be seen in figure 4-A, unfolding causes the thread to unfolded delivery reel (2) has a twist in the Z direction with a twist value prior to the twist means (λ) that is equal to:
(λ) = (1/(DI2) *3,1416), (λ) = (1/(DI2) *3.1416),
En este caso, cuando los medios de torsión aplican una torsión (Ω) en dirección Z, la torsión (Ω) debe equivaler a: Ω (tpm) = (1/(DI1 ) *3,1416) - (1/(DI2) *3,1416) donde: rpm de los medios de torsión (300) / 2 = Ω (tpm) * velocidad lineal hilo. con el objetivo de que el valor de la torsión del hilo plegado (α) a lo largo de toda la bobina de recogida (1 ) sea variable y esté asociada al diámetro instantáneo de enrolladlo/desenrollado (DI) de la propia bobina de recogida (1 ) y equivale a: α (tpm) = 1/(DI(m) * TT) In this case, when the torque means apply a torque (Ω) in the Z direction, the torque (Ω) must equal: Ω (tpm) = (1/(DI1 ) *3.1416) - (1/(DI2 ) *3.1416) where: torque media rpm (300) / 2 = Ω (tpm) * wire linear speed. with the aim that the value of the twist of the folded wire (α) along the entire collection reel (1) is variable and is associated with the instantaneous winding/unwinding diameter (DI) of the collection reel itself ( 1 ) and is equivalent to: α (tpm) = 1/(DI(m) * TT )
En cambio, cuando en este caso los medios de torsión aplican una torsión (Ω) en dirección S, la torsión (Ω) debe equivaler a: Ω (tpm) = (1/(DI1 ) *3,1416) + (1/(DI2) *3,1416) donde: rpm de los medios de torsión (300) / 2 = Ω (tpm) * velocidad lineal del hilo. con el objetivo de que el valor de la torsión del hilo plegado (α) a lo largo de toda la bobina de recogida (1 ) sea variable y esté asociada al diámetro instantáneo de enrolladlo/desenrollado (DI) de la propia bobina de recogida (1 ) y equivale a: α (tpm) = 1/(DI(m) * TT) Tal y como se observa en la figura 4-B, el desplegado provoca que el hilo desplegado tenga una torsión en sentido S con un valor de torsión previo a los medios de torsión (λ) que equivale a: On the other hand, when in this case the torsion means apply a torsion (Ω) in the S direction, the torsion (Ω) must be equal to: Ω (tpm) = (1/(DI1 ) *3.1416) + (1/ (DI2) *3.1416) where: torque media rpm (300) / 2 = Ω (tpm) * linear speed of the wire. with the aim that the value of the twist of the folded wire (α) along the entire collection reel (1) is variable and is associated with the instantaneous winding/unwinding diameter (DI) of the collection reel itself ( 1 ) and is equivalent to: α (tpm) = 1/(DI(m) * TT ) As can be seen in figure 4-B, unfolding causes the unfolded yarn to have a twist in the S direction with a value of twist prior to the means of twist (λ) equal to:
(λ) = (1/(DI2) *3,1416), (λ) = (1/(DI2) *3.1416),
En este caso, cuando los medios de torsión aplican una torsión (Ω) en dirección Z, la torsión (Ω) debe equivaler a: In this case, when the torque means apply a torque (Ω) in the Z direction, the torque (Ω) must equal:
Ω (tpm) = (1/(DI1 ) *3,1416) + (1/(DI2) *3,1416) donde: rpm de los medios de torsión (300) / 2 = Ω (tpm) * velocidad lineal del hilo. con el objetivo de que el valor de la torsión del hilo plegado (α) a lo largo de toda la bobina de recogida (1 ) sea variable y esté asociada al diámetro instantáneo de enrolladlo/desenrollado (DI) de la propia bobina de recogida (1 ) y equivale a: α (tpm) = 1/(DI(m) * TT) Ω (tpm) = (1/(DI1 ) *3.1416) + (1/(DI2) *3.1416) where: torque media rpm (300) / 2 = Ω (tpm) * linear speed of the thread. with the aim that the value of the twist of the folded wire (α) along the entire collection reel (1) is variable and is associated with the instantaneous winding/unwinding diameter (DI) of the collection reel itself ( 1 ) and is equivalent to: α (tpm) = 1/(DI(m) * TT )
En cambio, cuando en este caso los medios de torsión aplican una torsión (Ω) en dirección S, la torsión (Ω) debe equivaler a: Ω (tpm) = (1/(DI1 ) *3,1416) - (1/(DI2) *3,1416) donde: rpm de los medios de torsión (300) / 2 = Ω (tpm) * velocidad lineal. On the other hand, when in this case the torsion means apply a torsion (Ω) in the S direction, the torsion (Ω) must be equal to: Ω (tpm) = (1/(DI1 ) *3.1416) - (1/ (DI2) *3.1416) where: torque media rpm (300) / 2 = Ω (tpm) * linear speed.
Existen diversas tecnologías para obtener el valor del diámetro instantáneo de una bobina a lo largo de todo el proceso, tal como un sensor de ultrasonidos que se orienta adecuadamente para que proporcione una señal analógica asociada a una distancia a un autómata programable o PLC y que este a través y medios de programación calcule dicho diámetro instantáneo. También es posible conocer el diámetro instantáneo de una bobina conociendo la velocidad del hilo, las características del hilo y la geometría del plegado de la bobina. There are various technologies to obtain the value of the instantaneous diameter of a coil throughout the entire process, such as an ultrasound sensor that is properly oriented so that it provides an analog signal associated with a distance to a programmable controller or PLC and that this through and means of programming calculate said diameter instant. It is also possible to know the instantaneous diameter of a bobbin by knowing the speed of the wire, the characteristics of the wire and the geometry of the folding of the bobbin.
No se considera necesario entrar en detalle de cuál es la manera de cómo tuercen estas máquinas textiles, aunque preferentemente la presente invención se centra en que dichas máquinas se caracterizan porque a través de conocer el diámetro instantáneo de la bobina durante todo el ciclo de torcido y a través de medios de programación, pueden aplicar una torsión real al hilo bobinado que es variable tal que el valor de la torsión del hilo plegado (α) a lo largo de toda la bobina de recogida (1 ) sea variable, esté asociada al diámetro instantáneo de enrolladlo/desenrollado (DI) de la propia bobina de recogida (1 ) y equivalga a: α (tpm) = 1/(DI(m) * TT) It is not considered necessary to go into detail about the way in which these textile machines twist, although preferably the present invention focuses on the fact that said machines are characterized in that by knowing the instantaneous diameter of the reel during the entire twisting cycle, through programming means, they can apply a real twist to the wound thread that is variable such that the twist value of the folded thread (α) along the entire take-up reel (1) is variable, is associated with the instantaneous diameter winding/unwinding (DI) of the take-up reel itself (1 ) and is equal to: α (tpm) = 1/(DI(m) * TT )
En definitiva, para obtener una torsión real (α) en la bobina de recepción (1 ) se debe de programar una torsión (Ω) en la maquina retorcedora y según el principio de funcionamiento de la maquina como si es del tipo de anillos o de doble torsión (2x1 ), cada máquina actuará en sus partes móviles según convenga: In short, to obtain a real torque (α) in the receiving coil (1), a torque (Ω) must be programmed in the twisting machine and according to the operating principle of the machine as if it is of the type of rings or of double torsion (2x1), each machine will act on its moving parts as appropriate:
Para máquinas de retorcido de anillos: For ring twisting machines:
RPM bobina (1 ) = (Ω) * velocidad lineal hilo Winding RPM (1 ) = (Ω) * wire linear speed
Para máquinas de retorcido de doble torsión o 2x1 : For double twist or 2x1 twisting machines:
RPM medios de torsión (300) / 2 = (Ω) * velocidad lineal hilo Average Torque RPM (300) / 2 = (Ω) * Linear Yarn Speed
Cuando hablamos del valor cero torsiones significa que el objetivo de torsión es cero tpm aunque se debe tener en cuenta las tolerancias tanto de medición de los diámetros DI, DI2 y la precisión de los movimientos serán tales que siempre están buscando dicho objetivo, por tanto debe haber un margen entorno al valor 0 tpm que preferentemente es de +8/-8 tpm en el que se considere protegido por dicha presente invención, incluso márgenes de +1/-1 tpm o +2/-2tpm, +3/-3tpm. When we speak of the value zero twists, it means that the objective of torsion is zero tpm, although the tolerances for both DI and DI2 diameter measurements must be taken into account, and the precision of the movements will be such that they are always seeking said objective, therefore there must be a margin around the 0 tpm value, which is preferably of +8/-8 tpm in which it is considered protected by said present invention, including margins of +1/-1 tpm or +2/-2 tpm, +3/-3 tpm.
Descrita suficientemente la naturaleza de la presente invención, así como la manera de ponerla en práctica, no se considera necesario hacer más extensa su explicación para que cualquier experto en la materia comprenda su alcance y las ventajas que de ella se derivan. Having sufficiently described the nature of the present invention, as well as the way of putting it into practice, it is not considered necessary to make its explanation more extensive so that any person skilled in the art understands its scope and the advantages derived from it.
