Abstract

Il est disposé à l'intérieur d'un manchon (3) réunissant deux tubes (1, 2) propres à constituer la partie centrale d'une broche à double torsion. Une capsule (8) traversant la queue plate (13) d'un piston (12) est disposée à l'intérieur du manchon, ses extrémités prenant appui contre les débouchés de l'alésage (1c) du tube (1) et contre celui du trou central (6c) d'un embout monté à l'extrémité inférieure du tube (2). Lorsqu'on envoie de l'air comprimé dans l'alésage (1c) on provoque le retrait du piston (12) qui entraîne un décalage latéral de la capsule permettant ainsi le passage du fil tout le long de l'alésage de la broche.It is arranged inside a sleeve (3) joining two tubes (1, 2) suitable for constituting the central part of a double twist spindle. A capsule (8) passing through the flat tail (13) of a piston (12) is disposed inside the sleeve, its ends bearing against the outlets of the bore (1c) of the tube (1) and against that the central hole (6c) of a nozzle mounted at the lower end of the tube (2). When compressed air is sent into the bore (1c), the piston (12) is withdrawn, which causes a lateral offset of the capsule, thus allowing the passage of the wire all along the bore of the spindle.

Description

La présente invention est relative à des perfectionnements apportés aux systèmes d'enfilage pneumatique du fil dans l'alésage d'une broche à double torsion, cet alésage étant pourvu d'un frein de fil.The present invention relates to improvements made to pneumatic threading systems for the wire in the bore of a double twist spindle, this bore being provided with a wire brake.

On a décrit dans le brevet 77 22839 au nom de la présente Demanderesse un dispositif du genre en question qui donne tout à fait satisfaction sur le plan technique. Malheureusement sa réalisation est complexe et il comprend un nombre important de pièces de sorte que son prix de revient est élevé.There has been described in patent 77 22839 in the name of the present Applicant a device of the kind in question which is entirely satisfactory on the technical level. Unfortunately its realization is complex and it includes a large number of parts so that its cost price is high.

Les perfectionnements qui font l'objet de la présente invention visent à remédier aux inconvénients du brevet précité.The improvements which are the subject of the present invention aim to remedy the drawbacks of the aforementioned patent.

Le dispositif d'enfilage pneumatique suivant l'invention comporte un très faible nombre de pièces si bien que sa construction est très économique. Au lieu de prévoir deux alésages côte à côte dans la broche, L'air comprimé utilisé par le dispositif suivant l'invention est introduit dans cette broche par son alésage usuel par lequel passe.le fil à retordre. La broche est réalisée grâce à deux tubes réunis par un manchon de liaison dans lequel sont disposés des moyens de déplacer latéralement le frein de fil par rapport audit alésage quand l'air sous pression est introduit dans ce dernier. Le frein de fil, qui est réalisé sous la forme d'une capsule télescopique usuelle, dégage alors l'alésage et permet à un fil placé en tête de la broche d'être introduit librement dans son alésage.The pneumatic threading device according to the invention has a very small number of parts so that its construction is very economical. Instead of providing two bores side by side in the spindle, the compressed air used by the device according to the invention is introduced into this spindle by its usual bore through which the thread is twisted. The spindle is produced by two tubes joined by a connecting sleeve in which are arranged means for laterally moving the wire brake relative to said bore when the pressurized air is introduced into the latter. The wire brake, which is produced in the form of a usual telescopic capsule, then releases the bore and allows a wire placed at the head of the spindle to be freely introduced into its bore.

L'introduction du fil s'effectue au moyen d'un pistolet tel que celui décrit dans le brevet français 77 22839 précité de la Demanderesse.The introduction of the wire is carried out by means of a gun such as that described in the aforementioned French patent 77 22839 of the Applicant.

Le dessin annexé, donné à titre d'exemple, permettra de mieux comprendre l'invention les caractéristiques qu'elle présente et les avantages qu'elle est susceptible de procurer :

  • Fig. 1 est une coupe longitudinale d'une broche à double torsion pourvue d'un dispositif d'enfilage pneumatique établi conformément à l'invention.
  • Fig. 2 en est une coupe suivant II-II (fig. 1).
  • Fig. 3 est une vue partielle correspondant à fig. l mais montrant le frein de fil à sa position effacée.
  • Fig. 4 en est une coupe suivant IV-IV (fig. 3).
  • Fig. 5 est une vue semblable à celle de fig. 3 mais montrant le fil coincé par le frein de fil après qu'il ait été engagé dans l'alésage de la broche.
The attached drawing, given by way of example, will allow better understand the invention, the characteristics it presents and the advantages it is likely to provide:
  • Fig. 1 is a longitudinal section of a double twist spindle provided with a pneumatic threading device established in accordance with the invention.
  • Fig. 2 is a section along II-II (fig. 1).
  • Fig. 3 is a partial view corresponding to FIG. l but showing the wire brake in its cleared position.
  • Fig. 4 is a section on IV-IV (fig. 3).
  • Fig. 5 is a view similar to that of FIG. 3 but showing the wire jammed by the wire brake after it has been engaged in the spindle bore.

On a illustré en fig. 1 la partie centrale d'une broche à double torsion réalisée au moyen de deux tubes 1, 2 dont les extrémités sont filetées de manière à être réunies par l'intermédiaire d'un manchon 3.Illustrated in fig. 1 the central part of a double twist spindle produced by means of two tubes 1, 2, the ends of which are threaded so as to be joined by means of a sleeve 3.

On observe que le filetage la du tube 1 s'arrête à quelque distance de son extrémité pour déterminer une portée cylindrique lisse lb propre à coopérer avec un joint torique 4 du manchon 3. Une bague 5 coopère avec le filetage la du tube 1 pour déterminer la position relative de ce dernier par rapport au manchon 3.It is observed that the thread 1a of the tube 1 stops at some distance from its end to determine a smooth cylindrical seat 1b capable of cooperating with an O-ring 4 of the sleeve 3. A ring 5 cooperates with the thread 1a of the tube 1 to determine the relative position of the latter relative to the sleeve 3.

De même manière le tube inférieur 2 comporte un filetage 2a qui s'arrête avant l'extrémité du tube en vue de déterminer une portée cylindrique lisse 2b. A ce niveau le manchon comprend également un joint d'étanchéité 4' pour des raisons qu'on expliquera mieux plus loin. Ladite extrémité est associée à un embout étagé 6 percé de part en part et dont la partie à plus faible diamètre pénètre dans l'alésage 2c du tube 2. Entre l'épaulement 6a de l'embout 6 et l'extrémité annulaire du tube 2 est placé un ressort de compression 7.Similarly, the lower tube 2 has a thread 2a which stops before the end of the tube in order to determine a smooth cylindrical surface 2b. At this level, the sleeve also includes a seal 4 'for reasons which will be better explained below. Said end is associated with a stepped end-piece 6 pierced through and through and the part with a smaller diameter penetrates into the bore 2c of the tube 2. Between the shoulder 6a of the end-piece 6 and the annular end of the tube 2 a compression spring 7 is placed.

La partie à plus grand diamètre 6b de l'embout 6 est montée coulissante juste dans l'alésage 3a du manchon 3. Le débouché vers le haut du trou central 6c de l'embout 6 est chanfreiné de même que le débouché de l'alésage lc du tube 1. Les débouchés considérés sont reliés par le frein de fil usuel qui est réalisé au moyen d'une capsule 8 formée de deux éléments tubulaires télescopiques référencés 8a et 8b et dont les extrémités sont chacune fermées par une calotte sphérique. Un ressort de compression 9 est placé entre les deux éléments de la capsule 8 en vue de les écarter l'un de l'autre. Le réglage de la pénétration des tubes 1 et 2 dans le manchon 3 est destiné à permettre un écrasement convenable du ressort 9 par pénétration de l'élément 8b à l'intérieur de celui 8a.The larger diameter part 6b of the end piece 6 is slidably mounted just in the bore 3a of the sleeve 3. The outlet upwards from the central hole 6c of the end piece 6 is chamfered as is the outlet of the bore lc of the tube 1. The outlets considered are connected by the usual wire brake which is produced by means of a capsule 8 formed by two telescopic tubular elements referenced 8a and 8b and the ends of which are each closed by a spherical cap. A compression spring 9 is placed between the two elements of the capsule 8 in order to separate them from one another. The adjustment of the penetration of the tubes 1 and 2 in the sleeve 3 is intended to allow suitable crushing of the spring 9 by penetration of the element 8b inside that 8a.

Le manchon 3 est pourvu d'une saignée transversale 10 qui traverse son alésage central 3a pour parvenir dans un logement cylindrique 11 débouchant vers l'extérieur. Dans ce logement est engagé un piston 12 à tête cylindrique comportant une queue plate 13 qui s'enfile avec jeu dans la saignée 10. Un bouchon 14 ferme le débouché vers l'extérieur du logement 11. Ainsi l'alésage 3a du manchon 3 communique-t-il avec ledit logement.The sleeve 3 is provided with a transverse groove 10 which passes through its central bore 3a to reach a cylindrical housing 11 opening outwards. In this housing is engaged a piston 12 with a cylindrical head comprising a flat tail 13 which slides with clearance in the groove 10. A plug 14 closes the outlet towards the outside of the housing 11. Thus the bore 3a of the sleeve 3 communicates it with said housing.

On a illustré en fig. 2 la forme particulière de la queue 13 du piston 12. Celle-ci est en gros rectangulaire et elle comporte deux ouvertures circulaires sécantes l'une 13a d'un diamètre supérieur à celui de l'autre 13b. On notera que le diamètre extérieur de l'élément 8b de la capsule 8 présente un diamètre supérieur à la largeur de la lumière 13c faisant communiquer les deux ouvertures 13a et 13b pour des raisons qu'on expliquera mieux plus loin.Illustrated in fig. 2 the particular shape of the tail 13 of the piston 12. The latter is roughly rectangular and it comprises two intersecting circular openings one 13a with a diameter greater than that of the other 13b. It will be noted that the outside diameter of the element 8b of the capsule 8 has a diameter greater than the width of the opening 13c making the two openings 13a and 13b communicate for reasons which will be better explained below.

Préalablement à la mise en place de la capsule 8 dans le manchon 3 on place le piston 12 dans la position représentée en fig. l et 2 de manière que la capsule 8 puisse être engagée dans le trou 13a de la queue 13 de ce piston.Prior to placing the capsule 8 in the sleeve 3, the piston 12 is placed in the position shown in fig. l and 2 so that the capsule 8 can be engaged in the hole 13a of the tail 13 of this piston.

Le fonctionnement découle des explications qui précèdent : Lorsque le dispositif d'enfilage automatique ne fonctionne pas le piston 12 se trouve dans la position illustrée en fig. 1 et 2 c'est-à-dire que sa tête est en appui contre le fond du logement 11 tandis que les calottes sphériques des deux éléments 8a, 8b de la capsule 8 sont en appui contre les débouchés respectivement de l'alésage lc du tube 1 et du trou central 6c de l'embout 6.The operation follows from the above explanations: When the automatic threading device does not work, the piston 12 is in the position illustrated in FIG. 1 and 2, that is to say that its head is in abutment against the bottom of the housing 11 while the spherical caps of the two elements 8a, 8b of the capsule 8 are in abutment against the outlets respectively of the bore lc of the tube 1 and the central hole 6c of the nozzle 6.

Si l'on désire introduire un fil traversant les deux tubes 1 et 2 on présente au débouché supérieur de l'alésage lc du . tube 1 un pistolet tel que celui décrit dans la demande de brevet 77 23839 de la présente Demanderesse mais qui ne comporterait qu'un seul trou d'amenée d'air au lieu de deux. L'air arrivant sous pression dans l'alésage lc du tube 1 pénètre dans l'espace entourant la capsule 8 et vient sous la tête du piston 12 pour provoquer son déplacement vers la droite jusqu'à ce que la tête soit en appui contre le bouchon 14 (fig. 3). Ce déplacement du piston entraîne celui latéral de la capsule 8 dont les deux éléments s'interpénètrent élastiquement à l'encontre de la réaction du ressort 9 de telle sorte que les débouchés en vis-à-vis des tubes 1 et 2 sont libres. On observe que l'entraînement de la capsule 8 par la queue 13 du piston 12 s'effectue par appui des deux bords de la lumière 13c contre la périphérie de la capsule 8. Par suite de l'évasement des débouchés de l'alésage lc et du trou 6c de l'embout 6, on provoque une contraction du ressort 9.If one wishes to introduce a wire passing through the two tubes 1 and 2, one presents at the upper outlet of the bore lc. tube 1 a gun such as that described in patent application 77 23839 of the present Applicant but which would have only one air intake hole instead of two. The air arriving under pressure in the bore lc of the tube 1 enters the space surrounding the capsule 8 and comes under the head of the piston 12 to cause it to move to the right until the head is in abutment against the plug 14 (fig. 3). This displacement of the piston causes the lateral movement of the capsule 8, the two elements of which interpenetrate elastically against the reaction of the spring 9 so that the outlets facing the tubes 1 and 2 are free. It is observed that the driving of the capsule 8 by the tail 13 of the piston 12 is carried out by pressing the two edges of the light 13c against the periphery of the capsule 8. As a result of the widening of the outlets of the bore lc and from the hole 6c of the endpiece 6, the spring 9 is contracted.

En introduisant ensuite un fil 15 à l'extrémité libre de l'alésage lc, il est entraîné par l'air comprimé et passe dans le trou 6c de l'embout 6, puis dans celui 2c du tube 2 pour ressortir à l'endroit désiré de la broche à double torsion en ayant préalablement traversé le petit trou 13a de la queue 13 (fig. 4) lequel se trouve en gros dans l'axe géométrique des deux alésages lc, 2c.Then introducing a wire 15 at the free end of the bore lc, it is entrained by compressed air and passes through the hole 6c of the nozzle 6, then through that 2c of the tube 2 to come out at the place desired of the double twist spindle having previously crossed the small hole 13a of the tail 13 (fig. 4) which is roughly in the geometric axis of the two bores lc, 2c.

La description ci-dessus a été faite comme si l'embout 6 était solidaire de l'extrémité intérieure du tube 2. En réalité et sans que cela soit une obligation l'on préfère utiliser l'embout 6 et le ressort 7 de telle sorte qu'une fois l'air arrivé dans la chambre formée au centre de l'alésage 3a du manchon 3 il provoque une légère descente de l'embout 6 qui favorise le déplacement latéral de la capsule 8 par l'intermédiaire de la queue 13 du piston 12.The above description has been made as if the end piece 6 was integral with the inner end of the tube 2. In reality and without this being an obligation it is preferable to use the nozzle 6 and the spring 7 so that once the air has arrived in the chamber formed in the center of the bore 3a of the sleeve 3 it causes a slight lowering of the nozzle 6 which promotes lateral movement of the capsule 8 by means of the tail 13 of the piston 12.

Bien entendu les joints 4, 4' évitent toute sortie d'air entre le manchon et respectivement les tubes 1 et 2.Of course the seals 4, 4 ′ prevent any air from escaping between the sleeve and the tubes 1 and 2 respectively.

Un fois que le fil est ressorti dans le bas de la broche on arrête l'émission d'air comprimé. L'action du ressort 9 par rapport aux deux éléments télescopiques 8a, 8b de la capsule 8 ainsi qu'éventuellement le déplacement vers le haut de l'embout 6 provoquent le retour vers le centre de la capsule qui entraîne celui du piston 12 à sa position initiale (fig. 5) toujours par action de la capsule contre les bords de la lumière 13c. Le fil 15 est alors pincé entre les deux extrémités de la capsule 8 et les débouchés de l'alésage lc du tube 1 et de celui 6c de l'embout 6.Once the wire has come out at the bottom of the spindle, the emission of compressed air is stopped. The action of the spring 9 relative to the two telescopic elements 8a, 8b of the capsule 8 as well as possibly the upward displacement of the endpiece 6 cause the return to the center of the capsule which causes that of the piston 12 to its initial position (fig. 5) always by action of the capsule against the edges of the lumen 13c. The wire 15 is then pinched between the two ends of the capsule 8 and the outlets of the bore lc of the tube 1 and of that 6c of the nozzle 6.

On sait que le coincement n'est pas important mais qu'il est indispensable pour équilibrer La tension du ballon formé par le fil autour de la broche à double torsion. Le fil défile donc entre les extrémités de la capsule 8 et leurs points de contact en se déplaçant périphériquement autour des deux extrémités considérées de telle sorte que l'usure de la capsule, de l'embout 6 et du tube 1 est bien répartie.We know that the wedging is not important but that it is essential to balance the tension of the balloon formed by the wire around the double twist spindle. The wire therefore passes between the ends of the capsule 8 and their contact points by moving peripherally around the two ends considered so that the wear of the capsule, the end piece 6 and the tube 1 is well distributed.

On a ainsi réalisé un dispositif d'enfilage pneumatique du fil dans une broche à double torsion qui est particulièrement efficace tout en étant d'un prix de revient très modeste.A pneumatic threading device has thus been produced in a double twist spindle which is particularly effective while being very modest in cost.
