Abstract

A textile yarn bobbin winder consists of a feeder (1) for the bobbin rollers, made in the form of a chamber which holds the rollers (2) in a single file to provide a continuous circulation. The yarn is fed to the next roller to be wound by an articulated arm with an oscillating plate, and the feeder makes an angular movement before and after receiving a new roller. The next roller to be wound leaves the chamber and is picked up by transporter arms (3) and after winding is passed to the cutting zone for the end of the yarn to be cut.

Description

La présente invention concerne un procédé et une machine pour bobiner du fil textile.The present invention relates to a method and a machine for winding textile yarn.

ANTÉCÉDENTS DE L'INVENTIONBACKGROUND OF THE INVENTION

On connaît déjà des procédés pour bobiner du fil textile, du type comprenant:

  • recueillir moyennant des bras de transport un rouleau placé dans un dispositif alimentateur,
  • déplacer les bras de transport du dispositif alimentateur jusqu'à la position de bobinage près d'un tambour d'entraînement et guidage du fil pendant le bobinage,
  • placer le fil dans le rouleau à bobiner,
  • effectuer le bobinage du fil autour du rouleau,
  • déplacer les bras de transport qui portent la bobine terminée jusque près de la position de charge d'un nouveau rouleau,
  • décharger la bobine terminée dans la zone de décharge,
  • couper le fil, et
  • évacuer la bobine terminée.
Processes are already known for winding textile yarn, of the type comprising:
  • collect by means of transport arms a roll placed in a feeder device,
  • move the transport arms of the feeder device to the winding position near a drive drum and guide the wire during winding,
  • place the thread in the winding roll,
  • wind the wire around the roller,
  • move the transport arms carrying the completed reel to near the loading position of a new roller,
  • unload the finished coil in the discharge zone,
  • cut the wire, and
  • evacuate the finished coil.

Il y a actuellement plusieurs types de machines à bobiner du fil textile qui effectuent le bobinage du fil textile selon le procédé décrit. Plus précisement, on connaît des machines à bobiner du fil textile du type comprenant un dispositif alimentateur de rouleaux dans lequel une pluralité de ceux-ci y est arrangée, des bras de transport du rouleau, du dispositif alimentateur de rouleaux jusque la zone de bobinage, des moyens pour conduire l'extrémité du fil juqu'au rouleau à bobiner, un tambour d'entraînement et guidage du fil pendant le bobinage, un dispositif pour recevoir la bobine déjà faite, des moyens à couper le fil après formation de la bobine, des moyens de contrôle des dispositifs d'actionnement des mécanismes, et une structure de support de l'ensemble des éléments de la machine.There are currently several types of textile thread winding machines which carry out the winding of the textile thread according to the process described. More precisely, machines are known for winding textile yarn of the type comprising a device for feeding rolls in which a plurality of these are arranged there, arms for transporting the roll, from the device for feeding rolls to the winding zone, means for leading the end of the wire to the winding roller, a drum for driving and guiding the wire during winding, a device for receiving the already made reel, means for cutting the wire after forming the reel, means for controlling the devices for actuating the mechanisms, and a support structure of all the elements of the machine.

Ces machines présentent quelques inconvénients, particulièrement du point de vue de la fiabilité de fonctionnement et de la compléxité constructive.These machines have some drawbacks, particularly from the point of view of operating reliability and constructive complexity.

Plus précisement, le dispositif alimentateur de rouleaux est une enceinte prismatique dans laquelle les rouleaux sont empilés formant plusieurs colonnes dans la même enceinte. Avec cet arrangement des rouleaux on ne peut pas éviter des coincements accidentels lorsque plus d'un rouleau se trouvent dans la position de sortie.More precisely, the roller feeder device is a prismatic enclosure in which the rollers are stacked forming several columns in the same enclosure. With this arrangement of rollers, accidental jamming cannot be avoided when more than one roller is in the exit position.

Le système pour saisir le file pour commencer une nouvelle bobine est constitué par des pinces ou analogues qui ne garantissent pas toujours une correcte prise et un correct déplacement du fil.The system for gripping the line to start a new reel is constituted by pliers or the like which do not always guarantee a correct grip and a correct displacement of the wire.

En plus, la coupe du fil, une fois la bobine terminée, est réalisée par moyen d'une feuille de coupe qui pose des problèmes de fiabilité.In addition, the cutting of the wire, once the spool is finished, is carried out by means of a cutting sheet which poses reliability problems.

Enfin, le bâti de la machine est en fonte, ce qui comporte un poids et un coût de construction relativement élevés.Finally, the machine frame is made of cast iron, which has a relatively high weight and construction cost.

DESCRIPTION DE L'INVENTIONDESCRIPTION OF THE INVENTION

Avec la machine de l'invention on réussit a résoudre les inconvénients mentionnés.With the machine of the invention one succeeds in solving the drawbacks mentioned.

La machine pour bobiner du fil textile, objet de l'invention, est caractérisée en ce que le dispositif alimentateur de rouleaux comprend une enceinte qui enferme les rouleaux arrangés sur une seule file de façon à assurer une circulation continue des rouleaux, l'un après l' autre.The machine for winding textile thread, object of the invention, is characterized in that the roller feeder device comprises an enclosure which encloses the rollers arranged in a single row so as to ensure continuous circulation of the rollers, one after the other.

De cette façon on évite les coincements dans la livraison des rouleaux, lorsque plus d'un rouleaux se trouvent à la sortie du dispositif alimentateur.In this way, jams are avoided in the delivery of the rollers, when more than one roller is at the outlet of the feeder device.

Afin d'augmenter sa capacité, l'enceinte qui enferme les rouleaux comprend avantageusement deux tronçons formant angle.In order to increase its capacity, the enclosure which encloses the rollers advantageously comprises two sections forming an angle.

En plus, le dispositif alimentateur de rouleaux est articulé sur un support solidaire à la structure pour permettre un déplacement angulaire dans la zone de sortie des rouleaux. Grâce à ce mouvement du dispositif alimentateur, le mouvement des bras de transport est simplifié.In addition, the roller feeder device is articulated on a support integral with the structure to allow angular movement in the exit zone of the rollers. Thanks to this movement of the feeder device, the movement of the transport arms is simplified.

Les bras de transport sont à structure simple. Ils comprennent deux barres unies par une extrémité à un arbre giratoire dans la structure de support, lesdites barres étant munies dans l'autre extrémité des respectifs dispositifs de centrage pour saisir un rouleau, l'un des dispositifs de centrage étant mobile. Lorsqu'on actionne le vérin pneumatique, les dispositifs de centrage sont introduits dans des respectifs logements aménagés dans les extrémités du rouleau, le retenant.The transport arms are simple in structure. They comprise two bars joined at one end to a revolving shaft in the support structure, said bars being provided at the other end with the respective centering devices for gripping a roller, one of the centering devices being movable. When the pneumatic cylinder is actuated, the centering devices are introduced into respective housings arranged in the ends of the roller, retaining it.

La machine de l'invention comprend aussi un dispositif détecteur de diamètre de la bobine monté avec position réglable dans la structure de support. Ce détecteur est associé à une traverse unie aux deux barres des bras de transport.The machine of the invention also comprises a device for detecting the diameter of the coil mounted with adjustable position in the support structure. This detector is associated with a cross member joined to the two bars of the transport arms.

Selon une réalisation préférée, les moyens pour conduire l'extrémité du fil jusqu'au rouleau à bobiner comprennent un bras articulé sur l'arbre du tambour d'entraînement et guidage du fil, ce bras comprenant dans son extrémité un axe sur lequel oscille une plaque qui laisse passer le fil d'un côté à l'autre du rouleau lorsque celui-ci est en position de bobinage.According to a preferred embodiment, the means for leading the end of the wire to the winding roller comprise an arm articulated on the shaft of the drive drum and guiding the wire, this arm comprising at its end an axis on which a plate which lets the thread pass from one side to the other of the roll when the latter is in the winding position.

Avec ce dispositif on peut éviter les systèmes de prise du fil constitués par des pinces ou analogues qui posent d'importants problèmes de fiabilité.With this device it is possible to avoid the wire gripping systems constituted by pliers or the like which pose significant reliability problems.

La machine présente aussi autres détails constructifs tels que le dispositif pour recevoir la bobine déjà faite, lequel comprend un boîtier articulé sur un axe proche d'une de ses arêtes, ce boîtier se déplaçant d'une position de réception de la bobine jusqu'une position d'évacuation. Ainsi, la bobine est évacuée d'un simple tour de 90° à peu près.The machine also has other constructive details such as the device for receiving the already made coil, which comprises a housing articulated on an axis close to one of its edges, this housing moving from a position for receiving the coil to a evacuation position. Thus, the coil is evacuated with a simple turn of approximately 90 °.

La coupe du fil est une des phases qui posent des problèmes de fiabilité dans les machines actuelles. Dans la machine de l'invention, les moyens pour la coupe du fil comprennent deux feuilles de coupe articulées sur un axe monté sur une traverse, chaque feuille étant actionné par le respectif vérin pneumatique dans l'extrémité opposée à la zone de coupe. La coupe est donc effectuée par l'action simultanée de deux feuilles, en atteignant une grande fiabilité de coupe.Cutting the thread is one of the phases that pose reliability problems in today's machines. In the machine of the invention, the means for cutting the wire comprise two cutting sheets articulated on an axis mounted on a cross-member, each sheet being actuated by the respective pneumatic cylinder in the end opposite to the cutting area. The cutting is therefore carried out by the simultaneous action of two sheets, achieving high cutting reliability.

Par ailleurs, les moyens pour la coupe du fil comprennent un ressort monté sur l'axe d'articulation, pour maintenir constante la pression latérale entre les feuilles de coupe, et comprennent aussi un écrou vissé sur l'axe d'articulation afin de régler la tension du ressort.Furthermore, the means for cutting the wire comprise a spring mounted on the hinge pin, to keep the lateral pressure between the cutting sheets constant, and also include a nut screwed on the hinge pin in order to adjust spring tension.

Les moyens de contrôle comprennent un automate programmable pour le contrôle automatique des actionneurs, et une pluralité de boutons-poussoirs arrangés sur un boîtier monté dans la partie frontale de la machine, ce boîtier jouant aussi le rôle de guide-fil pour conduire le fil jusqu'au tambour d'entraînement et guidage.The control means include a programmable automaton for the automatic control of the actuators, and a plurality of push-buttons arranged on a box mounted in the front part of the machine, this box also playing the role of wire guide for leading the wire to 'to the drive and guide drum.

Enfin, la structure de support de l'ensemble d'élements de la machine comprend essentiellement deux plaques latérales unies par une pluralité de traverses, étant montés sur les plaques l'arbre du tambour d'entraînement et guidage, l'axe des bras de transport l'axe du boîtier de réception et évacuation de la bobine, et le support du dispositif alimentateur des rouleaux.Finally, the support structure of the set of machine elements essentially comprises two side plates joined by a plurality of crosspieces, being mounted on the plates of the drive drum shaft. and guidance, the axis of the transport arms, the axis of the receiving and discharging box of the coil, and the support of the device for feeding the rollers.

Cette structure est beaucoup plus simple que les bâtis en fonte habituellement utilisés.This structure is much simpler than the cast iron frames usually used.

On décrit ensuite le fonctionnement de la machine de l'invention:
   Préalablement, on doit arranger les rouleaux 2 dans le dispositif alimentateur 1.Next, the operation of the machine of the invention is described:
Beforehand, the rollers 2 must be arranged in the feeder device 1.

Tel qu'ils montrent les figures 1 et 2, les bras 3 se déplacent dans le sens de la flèche A, de la position représentée sur la figure 1 jusque la position représentée avec de traits discontinus sur la figure 2. Dans la position de cette figure, les bras 3 prennent le premier rouleau 2 placé dans le dispositif alimentateur 1.As shown in Figures 1 and 2, the arms 3 move in the direction of arrow A, from the position shown in Figure 1 to the position shown with broken lines in Figure 2. In the position of this figure, the arms 3 take the first roller 2 placed in the feeder device 1.

Ensuite, le dispositif alimentateur 1 est déplacé angulairement dans le sens de la flèche B, afin que le rouleau 2 puisse sortir après avoir été pris par les bras de transport 3.Then, the feeder device 1 is angularly moved in the direction of the arrow B, so that the roller 2 can come out after being picked up by the transport arms 3.

Ensuite, les bras de transport 3 se déplacent du dispositif alimentateur 1 jusqu'à la position de bobinage, auprès du tambour 4, dans le sens de la flèche C. En même temps, le dispositif alimentateur 1 vient à sa position originale se déplaçant dans le sens de la flèche D. À ce moment-ci, le rouleau se trouve dans la position représentée sur la figure 1.Then, the transport arms 3 move from the feeder device 1 to the winding position, near the drum 4, in the direction of the arrow C. At the same time, the feeder device 1 comes to its original position moving in the direction of arrow D. At this time, the roller is in the position shown in Figure 1.

L'opération suivante consiste à placer le fil 27 dans le rouleau 2 à bobiner. Selon l'invention, le fil 27 est accompagné de la zone de coupe jusqu'à la partie antérieure du rouleau 2, dans la position représentée sur la figure 4.The following operation consists in placing the wire 27 in the roller 2 to be wound. According to the invention, the wire 27 is accompanied by the cutting zone up to the front part of the roller 2, in the position shown in FIG. 4.

Cette disposition du fil rend possible le commencement du bobinage dans le rouleau lorsque le tambour 4 tourne. Le bobinage est effectué tandis que ce tambour tourne.This arrangement of the wire makes it possible to start winding in the roller when the drum 4 rotates. The winding is carried out while this drum rotates.

Une fois la bobine terminée, cette-ci se déplace avec les bras de trasnport 3 jusqu'à côté du dispositif alimentateur 1. Alors la bobine terminée 51 est déchargée dans le boîtier 38 (figure 8) et le fil est coupé avec le dispositif de coupe de la figure 5, lorsque les vérins 36,37 sont actionnés.Once the reel is finished, it moves with the transport arms 3 to the side of the feeder device 1. Then the finished reel 51 is discharged in the housing 38 (FIG. 8) and the wire is cut with the device section of Figure 5, when the cylinders 36,37 are actuated.

Ensuite, la bobine 51 est évacuée hors de la machine (figure 7), après que le boîtier 38 est basculée par l'action du vérin 41.Then, the coil 51 is removed from the machine (FIG. 7), after the housing 38 is tilted by the action of the jack 41.

La description effectuée plus haut correspond à une réalisation particulière de l'invention, mais on comprendra que toutes les possibles variantes accessibles à un homme du métier sont comprises dans la portée de celle-ci.The description given above corresponds to a particular embodiment of the invention, but it will be understood that all the possible variants accessible to a person skilled in the art are included in the scope thereof.
