Description

Tensor para bolsas de condensación.Condenser for condensation bags.

La presente invención está destinada a dar a conocer un tensor para bolsas de condensación del tipo utilizado en máquinas de hilatura para conseguir una mayor paralelización de las fibras dando lugar a una menor pilosidad a los hilos.The present invention is intended to give know a condenser for condensation bags of the type used in spinning machines to achieve greater parallelization of the fibers resulting in less hairiness to the threads.

Las bolsas de condensación actualmente conocidas están tensadas por unas barras dotadas de rebajes que actúan sobre varias bolsas sucesivas actuando por gravedad o mediante resortes, dando una ligera tensión a dichas bolsas. Estas barras de tensado actúan habitualmente sobre seis u ocho bolsas perforadas de manera que las máquinas de hilatura, que pueden llevar hasta 1400 o más bolsas perforadas, están divididas en tramos o secciones de seis u ocho posiciones (husos).The currently known condensation bags they are tensioned by bars equipped with recesses that act on several successive bags acting by gravity or by springs, giving a slight tension to these bags. These tension bars they usually act on six or eight perforated bags so than spinning machines, which can take up to 1400 or more perforated bags, are divided into sections or sections of six or eight positions (spindles).

Debido a las tolerancias de fabricación se tiene el efecto de que las bolsas perforadas no tienen todas exactamente el mismo diámetro interior. Este efecto de tolerancia se ve afectado asimismo por el trabajo a que están sometidas las bolsas y los elementos sobre los que descansan, aumentando de manera adicional las dimensiones individuales por factores tales como temperatura, humedad, rozamiento, etc.Due to manufacturing tolerances you have the effect that perforated bags don't have all exactly The same inner diameter. This tolerance effect is seen also affected by the work to which the bags are subjected and the elements on which they rest, increasing so additional individual dimensions by factors such as temperature, humidity, friction, etc.

Por lo tanto, en la actualidad, en el sistema de tensado mediante barra común de varias bolsas, éstos sólo pueden tensar dos bolsas que serán las que hayan quedado con el diámetro más pequeño puesto que las restantes no recibirán tensión. Ello tiene también por efecto el que la tensión que se había calculado para cada bolsa perforada quedará concentrada solamente en dos de ellas, en lugar de las que forman el grupo antes indicado de seis u ocho bolsas sobre los que actúa cada tramo del dispositivo. Además, según la posición de las bolsas más pequeñas con respecto a las restantes, la barra tensora puede adoptar una posición anómala comprometiendo incluso el guiado de las bolsas perforadas que se realiza mediante zonas rebajadas de dicha barra.Therefore, at present, in the system of tensioned by common bar of several bags, these can only tension two bags that will be the ones left with the diameter smaller since the rest will not receive tension. It it also has the effect that the voltage that had been calculated for each perforated bag it will be concentrated only in two of them, instead of those that form the above mentioned group of six or eight bags on which each section of the device acts. In addition, depending on the position of the smaller bags with respect to the remaining ones, the tension bar can adopt an anomalous position compromising even the guiding of the perforated bags that It is carried out through recessed areas of said bar.

Por otra parte, si a causa del uso, acumulación de suciedad, etc., una bolsa queda deteriorada, ello puede afectar la posición de la barra tensora perjudicando el buen funcionamiento de las bolsas restan-
tes.On the other hand, if, due to use, accumulation of dirt, etc., a bag is damaged, this may affect the position of the tension bar, impairing the proper functioning of the remaining bags.
tes.

Para solucionar los inconvenientes anteriormente indicados el inventor ha realizado pruebas y experimentaciones que han conducido a conseguir un dispositivo tensor para las bolsas de condensación que soluciona los inconvenientes anteriormente mencionados.To solve the problems above indicated the inventor has performed tests and experiments that have led to get a tensioning device for the bags of condensation that solves the problems above mentioned.

Esencialmente el tensor objeto de la presente invención está destinado a relacionar el elemento tubular de guiado de la bolsa de paralelización y la propia bolsa de manera directa y teniendo en cuenta además que se consiga un montaje sencillo y práctico. Para ello el tensor objeto de la presente invención presenta una zona de unión por simple pinzado a presión en el soporte de la bolsa y una zona de tensado directo sobre un extremo de esta última. Por lo tanto, presenta una estructura básicamente de dos piezas y un resorte intermedio. Las piezas pueden ser fabricadas por moldeo por inyección en materiales sintéticos y se caracterizan porque una de ellas está destinada a su unión por métodos fáciles al soporte de bolsa y la otra encaja en la primera recibiendo la acción de un resorte y actuando por el otro extremo en la bolsa presentando unas aletas laterales de guiado de la misma.Essentially the tensor object of the present invention is intended to relate the tubular guide element of the parallelization bag and the bag itself directly and taking into account that a simple assembly is achieved and practical. For this, the tensioner object of the present invention it presents a joint area by simple pressure clamping in the bag support and a direct tension zone on one end of the latter. Therefore, it presents a structure basically of two pieces and an intermediate spring. The pieces can be manufactured by injection molding in synthetic materials and it characterized because one of them is destined to join by easy methods to the bag holder and the other fits into the first receiving the action of a spring and acting on the other end in  the bag presenting lateral guide fins of the same.

Para su mejor comprensión se adjuntan a título de ejemplo explicativo pero no limitativo unos dibujos representativos de un tensor para bolsas de condensación de acuerdo con la presente invención.For your best understanding they are attached to title explanatory example but not limiting some drawings representative of a condenser bag tensioner according with the present invention.

La figura 1 muestra esquemáticamente una vista en alzado representativa de un tensor según la presente invención con su posicionamiento en el tensado de una bolsa de condensación de fibras.Figure 1 schematically shows a view in elevation representative of a tensioner according to the present invention with its positioning in the tension of a condensation bag of fibers.

La figura 2 muestra una vista en alzado frontal del propio tensor.Figure 2 shows a front elevation view from the tensor himself.

La figura 3 muestra una vista en alzado lateral del tensor.Figure 3 shows a side elevation view of the tensioner.

La figura 4 muestra una vista en perspectiva del propio tensor.Figure 4 shows a perspective view of the own tensioner.

Tal como se representa en las figuras, de acuerdo con la presente invención la bolsa perforada de condensación de fibras indicada con el numeral (1) se apoya sobre un rodillo giratorio (2) que es el que efectúa el arrastre de la bolsa por la tangencia ejercida por un rodillo de giro libre recubierto de goma (4) que actúa sobre la cinta al pasar esta por encima del rodillo motriz (2). Por ello la cinta (1) tiene igual velocidad que el rodillo de arrastre (2).As depicted in the figures, of according to the present invention the perforated bag of fiber condensation indicated by numeral (1) rests on a rotating roller (2) which is the one that drags the bag for the tangency exerted by a free spin roller covered with rubber (4) that acts on the tape when it passes through above the drive roller (2). Therefore the tape (1) has the same speed than the drive roller (2).

Un elemento tubular o perfil estático (3) recibe también la bolsa perforada, sobre todo en su parte superior ranurada (3'), estando conectado el interior de dicho elemento tubular a una fuente de vacío.A tubular element or static profile (3) receives also the perforated bag, especially at the top grooved (3 '), the inside of said element being connected tubular to a vacuum source.

Mediante esta disposición las fibras procedentes del tren de estiraje (5) quedan depositadas sobre la bolsa perforada (1), efectuándose una paralelización aerodinámica por el efecto de rotación y aspiración, con lo que se consigue un hilado sin apenas pilosidades.Through this arrangement the fibers coming of the stretch train (5) are deposited on the bag perforated (1), an aerodynamic parallelization being carried out by the rotation and aspiration effect, which results in spinning With hardly any hairiness.

El tensor objeto de la presente invención está destinado a efectuar el tensado de la bolsa (1) de manera individual, es decir, cada una de las bolsas de condensación tiene asignado un tensor individual. Ello es de gran importancia puesto que la rotación constante de la bolsa perforada sin deslizamiento sobre el rodillo giratorio (2) ni pérdidas ni variaciones de velocidad son muy importantes para conseguir elevadas velocidades de producción de hilado y alta calidad en el mismo, por lo que el tensor objeto de la presente invención mejora muy sensiblemente la calidad de los hilos en comparación con el estado de la técni-
ca.The tensioner object of the present invention is intended to tension the bag (1) individually, that is, each of the condensation bags has an individual tensioner assigned. This is of great importance since the constant rotation of the perforated bag without sliding on the rotating roller (2), neither losses nor speed variations are very important to achieve high spinning speeds and high quality in the same, so The tensioner object of the present invention greatly improves the quality of the threads compared to the state of the art.
