Abstract

Device for automatically inserting, by pneumatic route, a textile-fibre sliver into the coiler of a combing machine. It includes, immediately above the coiler, a complementary apparatus 5 ensuring simultaneously, by pneumatic route, the reinforcement of the sliver, its propulsion and its automatic insertion into the coiler.

Description

L'invention concerne les peigneuses pour la préparation à la filature de fibres textiles naturelles, artificielles bu synthétiques et elle a trait, plus particulièrement, à l'introduction d'une mèche dans le coller, pour sa mise en pot. The invention relates to combing machines for the preparation of natural, artificial or synthetic textile fibers for spinning and relates more particularly to the introduction of a wick into the paste, for its potting.

On sait que, dans ce domaine, cette introduction se fait manuellement. En fait, l'opérateur saisit le voile de fibres à sa sortie de la peigneuse et le roule entre les deux mains pour amorcer un boudin qu'il introduit dans un canal dont l'extrémité s'évase en forme d'entonnoir pour faciliter l'enfilage de la mèche dont le bout est ensuite pris par le coller. We know that, in this area, this introduction is done manually. In fact, the operator grasps the veil of fibers at his exit from the combing machine and rolls it between the two hands to initiate a sausage which he introduces in a channel whose end flares out in the form of a funnel to facilitate the threading of the wick, the end of which is then taken by gluing it.

Or cette manière de procéder est difficilement applicable aux machines rapides à grand étirage, car le voile de fibres qu'elles délivrent est si fin qu'il est pratiquement impossible de l'empoigner sans le déchirer. Par ailleurs,ce mode d'introduction de la mèche dans le coller prend beaucoup trop de temps dans la conduite d'une machine à haute production, alors que toutes les autres phases du travail se succèdent automatiquement. However, this way of proceeding is difficult to apply to fast stretching machines, because the veil of fibers which they deliver is so fine that it is practically impossible to grasp it without tearing it. Furthermore, this method of introducing the wick into the glue takes far too long in the operation of a high production machine, while all the other phases of the work follow one another automatically.

L'invention a pour but de supprimer toute intervention manuelle et, à cet effet, elle a pour objet un dispositif d'introduction automatique de la mèche de fibres dans le col- ler, caractérisé en ce qu'il comporte, immédiatement au-dessus du coller, un appareil complémentaire assurant, par voie pneumatique, à la fois le renforcement de la mèche, sa propulsion, et son introduction automatique dans le coller. The object of the invention is to do away with any manual intervention and, for this purpose, it relates to an automatic device for introducing the wick of fibers into the adhesive, characterized in that it comprises, immediately above of the paste, an additional device ensuring, pneumatically, both the strengthening of the wick, its propulsion, and its automatic introduction into the paste.

On conçoit aisément les avantages qu'apporte l'invention
D'une manière générale, le dispositif d'enfilage pneumatique apporte d'abord un enfilage plus régulier, ensuite un gain de temps considérable pour la machine et pour l'opera- teur, et enfin évite une manoeuvre longue et compliquée, ce qui devient d'autant plus intéressant que cette manoeuvre peut se présenter fréquemment.
We can easily see the advantages of the invention
In general, the pneumatic threading device firstly provides more regular threading, then a considerable time saving for the machine and for the operator, and finally avoids a long and complicated maneuver, which becomes all the more interesting as this maneuver can occur frequently.

Suivant une forme d'exécution, à laquelle la préférence semble devoir être donnée, l'appareil pneumatique , qui se pose directement sur l'entonnoir d'entrée du coller, et as sure le déplacement de la mèche, son renforcement et son enfilage automatique dans l'entonnoir du coller, comporte une arrivée d'air comprimé, une chambre annulaire recevant cet air et une série de petits conduits partant de ladite chambre et débouchant dans un canal central annulaire traversé par la mèche. According to an embodiment, to which preference seems to have to be given, the pneumatic device, which is placed directly on the inlet funnel of the glue, and ensures the movement of the wick, its reinforcement and its automatic threading in the funnel of the paste, comprises an inlet for compressed air, an annular chamber receiving this air and a series of small conduits starting from said chamber and opening into an annular central channel through which the wick passes.

D'autres caractéristiques et avantages de l'invention ressortiront de la description qui va suivre, et de l'examen des dessins annexées, qui font partie de la description, et montrent, à titre d'exemple, nullement limitatif, un mode de réalisation de l'invention. On se réfèrera au dessin annexé, dans lequel
Fig. 1 représente, en coupe longitudinale, le dispositif d'enfilage pneumatique tel qu'il est installé sur une peigneuse, et
Fig. 2 est une coupe transversale de la pièce tubulaire pourvue de moyens pneumatiques pour l'entraînement de la mèche.
Other characteristics and advantages of the invention will emerge from the description which follows, and from the examination of the appended drawings, which form part of the description, and show, by way of example, in no way limiting, an embodiment. of the invention. Refer to the accompanying drawing, in which
Fig. 1 shows, in longitudinal section, the pneumatic threading device as installed on a combing machine, and
Fig. 2 is a cross section of the tubular part provided with pneumatic means for driving the wick.

Dans le dessin, 1 désigne un guide transversal à surface lisse, qui reçoit le voile de fibres 2 venant du dispositif d'arrachage (non représenté) de la peigneuse, en l'espèce une peigneuse rectiligne ; le voile de fibres est ainsi condensé et mis sous forme de mèche 3. La référence 5 désigne, dans son ensemble, l'appareil qui assure le double rôle de renforcer le début de mèche, de le propulser et de l'enfiler dans l'entonnoir d'entrée du coller 4. In the drawing, 1 designates a transverse guide with a smooth surface, which receives the web of fibers 2 coming from the tearing device (not shown) of the comber, in this case a rectilinear comber; the veil of fibers is thus condensed and put in the form of a wick 3. The reference 5 designates, as a whole, the apparatus which ensures the dual role of reinforcing the start of the wick, of propelling it and of threading it into the glue inlet funnel 4.

A la sortie du coller se trouvent les rouleaux d'appel 6,6', de la mèche qui, ou bien tombe directement dans un pot ou bien, lors du peignage de certaines fibres manquant de cohesion, penetre dans une boîte à friser 7 située à la sortie de la machine, entre le chariot et le coller. At the exit of the glue are the rolls of call 6.6 ', the wick which either falls directly into a pot or else, when combing certain fibers lacking cohesion, enters a curling box 7 located at the exit of the machine, between the carriage and the glue.

En ce qui concerne le dispositif désigné par la référence 5 et que la Fig. 2 représente en coupe transversale, il est formé de deux corps tubulaires 5a et 5b, dont le premier 5a est raccordé à une canalisation d'air comprimé 8 et dont le second 5b est conformé et emboîté dans le premier de ma nière à créer une chambre annulaire 9 recevant l'air comprimé; un large canal 10 sert au passage de la mèche. Durant son trajet, celle-ci se trouve soumise au soufflage d'une série de petits conduits 11 reliant la chambre annulaire 9 au canal 10. With regard to the device designated by the reference 5 and that FIG. 2 shows in cross section, it is formed of two tubular bodies 5a and 5b, the first of which 5a is connected to a compressed air pipe 8 and the second of which 5b is shaped and fitted into the first in the way of creating a chamber annular 9 receiving compressed air; a wide channel 10 is used for the passage of the wick. During its journey, it is subjected to the blowing of a series of small conduits 11 connecting the annular chamber 9 to the channel 10.

Pour l'exécution de l'opération d'enfilage, de l'air comprimé est envoyé dans la canalisation 8 ; cet air sous pression se répartit dans la chambre annulaire 9, formée entre les deux corps tubulaires 5a et 5b, et pénètre dans le canal central 10 par les petits conduits 11. L'ensemble fonctionne à la maniere d'un venturi et aspire énergiquement le voile de fibres 2 qui s'engouffre dans le canal 10. Les petits conduits il débouchent dans le canal 10 tangentiellement à la surface intérieure de ce dernier et communiquent, de ce fait, un mouvement hélicoidal aux fibres, ce qui confère à la mèche ainsi constituée une certaine torsion propre à accroître sa solidité. For the execution of the threading operation, compressed air is sent into line 8; this pressurized air is distributed in the annular chamber 9, formed between the two tubular bodies 5a and 5b, and enters the central channel 10 through the small conduits 11. The whole operates in the manner of a venturi and energetically draws the fiber web 2 which rushes into the channel 10. The small conduits open into the channel 10 tangentially to the inner surface of the latter and communicate, therefore, a helical movement to the fibers, which gives the wick as well formed a certain twist to increase its strength.

La mèche 3 est alors prise et entraînée par les cylindres d'appel 6 et 6' qui l'envoient dans la boîte à friser 7. The wick 3 is then taken and driven by the call cylinders 6 and 6 'which send it to the crimping box 7.

L'enfilage pneumatique ne fonctionne, évidemment, que pendant l'introduction du début de la mèche 3, jusqu'à ce que ce début soit bien pris par les cylindres d'appel 6 et 6'et introduit dans la boite à friser 7, et est à l'arrêt durant tout le reste du fonctionnement normal de la machine. The pneumatic threading only functions, obviously, during the introduction of the start of the wick 3, until this start is well taken up by the call cylinders 6 and 6 ′ and introduced into the curling box 7, and is stopped during all the rest of the normal operation of the machine.

Il est bien entendu que l'invention ne se limite pas au mode de réalisation donné à titre d'exemple et que l'on pourra imaginer des- variantes, perfectionnements de détails et emplois de moyens équivalents sans, pour cela, sortir du cadre de protection la régissant.  It is understood that the invention is not limited to the embodiment given by way of example and that one can imagine variations, refinements of details and use of equivalent means without, for this, departing from the scope of protection governing it.
