Description

La présente invention concerne un perfectionnement apporté aux organes de commande du dispositif va-et-vient des guides distributeurs de fils lors d'une opération de bobinage.The present invention relates to an improvement made to the control members of the reciprocating device of the wire distributor guides during a winding operation.

Elle a trait plus particulièrement à un perfectionnement apporté au moyens permettant de faire varier la longueur des déplacements des guide-fils de manière à réaliser des enroulements de forme biconique.It relates more particularly to an improvement made to the means making it possible to vary the length of the movements of the wire guides so as to produce windings of biconical shape.

La réalisation d'enroulements de forme biconique est connue depuis très longtemps et consiste à faire varier progressivement la longueur de la course des différents organes de distribution du fil.The production of biconical windings has been known for a very long time and consists in gradually varying the length of the stroke of the various wire distribution members.

Pour ce faire, ainsi que cela est décrit notamment dans le brevet français 1 356 276, on utilise un système à came qui transmet un mouvement de va-et-vient à un corps support du guide-fil.To do this, as described in particular in French patent 1 356 276, a cam system is used which transmits a back and forth movement to a support body of the wire guide.

Ainsi que cela est montré dans ce document, le guide-fil est monté pivotant sur le corps support par l'intermédiaire d'un ensemble constitué essentiellement de deux bras disposés en équerre, le guide-fil étant disposé à l'extrémité de l'un-des bras et l'extrémité de l'autre bras étant équipée d'un galet coulissant le long d'une rainure pratiquée dans une barre, dite "barre sinus"; il est connu, par ailleurs, qu'en modifiant l'inclinaison de cette barre de sinus, on peut varier la course du guide-fil, ceci combiné avec une horloge ou en liaison avec le grossissement de la bobine, ce qui permet de faire des enroulements de forme biconique.As shown in this document, the wire guide is pivotally mounted on the support body by means of an assembly essentially consisting of two arms arranged at right angles, the wire guide being disposed at the end of the one of the arms and the end of the other arm being equipped with a roller sliding along a groove made in a bar, called "sine bar"; it is known, moreover, that by modifying the inclination of this sine bar, the stroke of the thread guide can be varied, this combined with a clock or in connection with the magnification of the spool, which makes it possible to do biconical windings.

Les guide-fils décrivent en extrémité deux rayons parallèles alors que le pivotement de la barre sinus se fait sur un arc de cercle dont le centre est situé sensiblement au milieu de-ladite barre, ce qui a pour résultat dela-décaler par rapport au chemin parcouru par le galet provo- ; quant une déformation de la bobine.The wire guides describe at the end two parallel spokes while the pivoting of the sine bar is done on an arc of circle whose center is located substantially in the middle of said bar, which results in dela-offset from the path traveled by the pebble provo-; as for a deformation of the coil.

Si un tel dispositif donne un compromis satisfaisant du point de vue textile, il impose des contraintes mécaniques et des vitesses de battements suivant le poids des guide-fils dû à l'inversion du mouvement en extrémité de course. Ces contraintes peuvent être réduites par l'utilisation d'un rayon de courbure important entre les rampes de came, mais ceci à des répercussions textiles car, le fil se dépose en plus grande quantité en extrémité de bobinage, ce qui provoque une déformation de la génératrice de la bonne.If such a device gives a satisfactory compromise from the textile point of view, it imposes mechanical stresses and beat speeds according to the weight of the thread guides due to the reversal of the movement at the end of the stroke. These constraints can be reduced by the use of a large radius of curvature between the cam ramps, but this has textile repercussions because, the wire is deposited in greater quantity at the winding end, which causes a deformation of the generator of the good.

Or, on a trouvé,et c'est ce qui fait l'objet de la présente invention, un perfectionnement aux dispositifs du type précité, qui surmonte ces inconvénients et permet la réalisation d'enroulements.biconiques parfaitement réguliers.However, we have found, and this is what is the subject of the present invention, an improvement to devices of the aforementioned type, which overcomes these drawbacks and allows the realization of perfectly regular windings.

D'une manière générale, l'invention concerne donc un perfectionnement apporté aux systèmes de commande des déplacements des guide-fils lors de la réalisation d'une bobine biconique, ces systèmes de commande étant du type comportant :

  • - une came à gorge hélicoïdale avec des rayons de pointe transmettant un.déplacement alternatif à un coulisseau commandant une barre s'étendant sur toute la longueur du métier,
  • - et pour chaque position de bobinage :
    • . un guide-fil monté pivotant sur un corps support solidaire de la barre précitée, ce guide-fil étant monté à l'extrémité d'un bras en équerre, dont l'autre extrémité comporte un galet qui est guidé dans la rainure d'une barre (barre sinus) inclinable en synchronisme avec la formation de l'enroulement.
In general, the invention therefore relates to an improvement made to the systems for controlling the displacements of the wire guides during the production of a biconical coil, these control systems being of the type comprising:
  • - a cam with a helical groove with pointed spokes transmitting an alternative movement to a slide controlling a bar extending over the entire length of the loom,
  • - and for each winding position:
    • . a wire guide pivotally mounted on a support body integral with the aforementioned bar, this wire guide being mounted at the end of an angle arm, the other end of which comprises a roller which is guided in the groove of a bar (sinus bar) tilting in synchronism with the formation of the winding.

Le perfectionnement selon l'invention se caractérise par le fait que les extrémités de la gorge de guidage de la barre sinus dans laquelle prend appui le galet commandant le déplacement angulaire du guide-fil, sont.recourbées en sens opposé, de manière à communiquer une accélération au guide-fil en fin de course, alors que le support dudit guide-fil a un mouvement retardé à ce moment dû au passage de la pointe de came, cette accélération permettant de distribuer le fil à vitesse constante ou accélérée.The improvement according to the invention is characterized by the fact that the ends of the guide groove of the sinus bar in which the roller controlling the angular displacement of the wire guide bears, are bent in opposite directions, so as to communicate a acceleration at the thread guide at the end of the stroke, while the support of said thread guide has a delayed movement at this time due to the passage of the cam tip, this acceleration making it possible to distribute the thread at constant or accelerated speed.

La course du guide-fil sera bien entendu fonction des enroulements formés. D'une manière générale, les rayons de pointe de came sont compris entre 10 et 100 millimètres et meuvent être exécutés suivant un "Lemniscate de Bernouilly" pour faciliter les ralentissements et accélérations des guide-fils. La correction sur la barre de sinus étant complémentaire aux formes de ces pointes et pouvant être plus accentuée de façon à accélérer les vitesses des guide-fils en bout de course. Par ailleurs, l'axe de pivotement de la parre sinus recevra également, en cours de formation de la bobine, un mouvement composé permettant de le déplacer légèrement de telle sorte que le galet provoquant le déplacement angulaire du guide- fil prenne toujours appui sur le même profil de la courbe prévue aux extrémités de la rainure de la barre sinus et ce quel que soit le diamètre de l'enroulement formé. Le mécanisme de liaison bobine barre sinus n'est pas représenté dans le brevet.The course of the wire guide will of course depend on the windings formed. In general, the cam tip radii are between 10 and 100 millimeters and can be executed using a "Lemniscate de Bernouilly" to facilitate deceleration and acceleration of the wire guides. The correction on the sine bar is complementary to the shapes of these points and can be further accentuated so as to accelerate the speeds of the wire guides at the end of their travel. In addition, the pivot axis of the sine shield will also receive, during the formation of the coil, a compound movement making it possible to move it slightly so that the roller causing the angular displacement of the thread guide always bears on the same profile of the curve provided at the ends of the groove of the sine bar and this whatever the diameter of the winding formed. The sine bar coil connection mechanism is not shown in the patent.

Le mouvement de la barre de sinus est produit au travers d'une course calculée de façon que la position moyenne de celle-ci corresponde avec les battements des guide-fils qui la parcourent.The movement of the sine bar is produced through a stroke calculated so that the mean position of the latter corresponds with the beats of the thread guides which traverse it.

L'invention et les avantages qu'elle apporte seront cependant mieux compris grâce à l'exemple de réalisation donné ci-après à titre illustratif mais non limitatif, et qui est illustré par les schémas annexés dans lesquels :

  • - la figure 1 est une vue schématique de dessus d'un dispositif de bobinage conforme à l'invention,
  • - la figure 2 est une vue de dessus agrandie montrant les déplacements de la barre sinus et des guide-fils en cours de bobinage,
  • - la figure 3 est une vue en perspective d'un dispositif conforme à l'invention.
The invention and the advantages which it brings will however be better understood thanks to the embodiment given below by way of illustration but not limitation, and which is illustrated by the appended diagrams in which:
  • FIG. 1 is a schematic top view of a winding device according to the invention,
  • FIG. 2 is an enlarged top view showing the movements of the sine bar and the wire guides during winding,
  • - Figure 3 is a perspective view of a device according to the invention.

Dans cet exemple de réalisation, l'invention sera décrite pour un dispositif permettant de.réaliser une bobine biconique ayant les caractéristiques suivantes :

  • - diamètre du tube support : 7 cm
  • - diamètre après bobinage : 25 cm
  • - course maximum (en début de bobinage) : 20 cm
  • - course minimum (en fin de bobinage) : 12 cm Pour réaliser un tel enroulement, on utilise, ainsi que cela est illustré par les figures annexées, un dispositif qui se compose essentiellement d'une came 2 dont les pointes sont réalisées avantageusement en Lemniscate, et qui comporte un chemin hélicoïdal permettant de communiquer un déplacement D de 16 cm, constant, à un coulisseau 3. Ce coulisseau 3 transmet son mouvement à une barre 20 stétendant sur toute la longueur de la machine, parallèlement à l'axe de bobinage, et qui supporte, pour chaque position, un corps support 9 sur lequel est monté pivotant un guide-fil 4. De manière connue, le guide-fil 4 est monté à l'extrémité d'un bras en équerre 21 dont l'autre extrémité 22 présente un galet 5 qui est guidé par la rainure 8 prévue dans une barre sinus 6 qui pivote autour d'un axe 7 en cours de formation de l'enroulement. Dans le cas présent, la barre sinus 6 peut être inclinée d'un angle de 10°, ce qui permet, compte-tenu de la longueur des branches du bras en équerre 21 supportant le guide-fil 4 d'obtenir une courbe du guide-fil variant entre une longueur L de 20 cm à une longueur 1 de 12 cm en fin de bobinage.
In this exemplary embodiment, the invention will be described for a device making it possible to develop a biconical coil having the following characteristics:
  • - diameter of the support tube: 7 cm
  • - diameter after winding: 25 cm
  • - maximum stroke (at the start of winding): 20 cm
  • - minimum stroke (at the end of winding): 12 cm To make such a winding, we use, as illustrated by the appended figures, a device which essentially consists of a cam 2 whose points are advantageously made of Lemniscate , and which comprises a helical path making it possible to communicate a constant displacement D of 16 cm, to a slide 3. This slide 3 transmits its movement to a bar 20 s t extending over the entire length of the machine, parallel to the axis winding, and which supports, for each position, a support body 9 on which is pivotally mounted a wire guide 4. In known manner, the wire guide 4 is mounted at the end of a square arm 21 whose l 'other end 22 has a roller 5 which is guided by the groove 8 provided in a sine bar 6 which pivots about an axis 7 during the formation of the winding. In the present case, the sinus bar 6 can be inclined at an angle of 10 °, which allows, taking into account the length of the arms of the square arm 21 supporting the wire guide 4 to obtain a curve of the guide -wire varying between a length L of 20 cm to a length 1 of 12 cm at the end of the winding.

Ces deux positions extrêmes de la barre sinus sont représentées en vue de dessus à la figure 2, la position en début de bobinage étant représentée en traits pleins et celle en fin de bobinage en traits mixtes.These two extreme positions of the sine bar are shown in plan view in FIG. 2, the position at the start of winding being shown in solid lines and that at the end of winding in dashed lines.

Conformément à l'invention, la rainure 8 de la barre sinus 6 présente à chacune de ses extrémités des parties courbes 10, 23 en sens opposé, qui permettent de communiquer au guide-fil, une accélération en fin de course, alors que le support 9 dudit guide-fil a un mouvement retardé à ce moment dû au fait du rayon de pointe de la came. Du fait de cette accélération, on obtient un mouvement du guide-fil identique à celui qui aurait été donné par une came à bouts pointus et une barre sinus classique comportant une rainure rectiligne. De la sorte,il est possible de réaliser des enroulements ayant les mêmes caractériques qu'antérieurement et ce à des vitesses de battements de deux à trois fois supérieures au système courant.According to the invention, the groove 8 of the sine bar 6 has at each of its ends curved parts 10, 23 in opposite directions, which allow to communicate to the wire guide, an acceleration at the end of the race, while the support 9 of said thread guide has a delayed movement at this time due to the tip radius of the cam. Because of this acceleration, a movement of the wire guide is obtained which is identical to that which would have been given by a cam with pointed ends and a conventional sinus bar comprising a rectilinear groove. In this way, it is possible to produce windings having the same characteristics as before. and this at beating speeds two to three times higher than the current system.

Dans le cas présent, la rainure de la barre sinus conforme à l'invention présente une partie rectiligne ayant une longueur de 14,8 centimètres, les parties courbes ayant un rayon de 2 centimètres, la longueur totale de la barre sinus 6 étant de 16 centimètres.In the present case, the groove of the sinus bar according to the invention has a rectilinear part having a length of 14.8 centimeters, the curved parts having a radius of 2 centimeters, the total length of the sinus bar 6 being 16 centimeters.

Par ailleurs, afin que lors de la formation de la bobine biconique le galet 5 de guidage travaille toujours sur le même profil de la courbe 10 ou 23 de façon à ne pas déformer le mouvement, l'axe de pivotement 7 de la barre sinus peut être déplacé-entre deux positions 11, 12. Ce déplacement est obtenu en prévoyant dans la barre sinus . une lumière 24 dans laquelle est guidé l'axe 7. Ce déplacement est obtenu en synchronisme avec le déplacement angulaire de ladite barre sinus grâce à l'action d'un doigt de guidage 13 qui prend appui dans une rainure 14 de la barre.Furthermore, so that during the formation of the biconical coil the guide roller 5 always works on the same profile of the curve 10 or 23 so as not to deform the movement, the pivot axis 7 of the sinus bar can be moved between two positions 11, 12. This movement is obtained by providing in the sine bar. a light 24 in which the axis 7 is guided. This movement is obtained in synchronism with the angular movement of said sinus bar by the action of a guide finger 13 which is supported in a groove 14 of the bar.

Le dispositif faisant la liaison entre la bobine et la barre sinus n'est pas représenté dans le brevet. Grâce à une telle installation, il a été possible de bobiner des fils textiles, des filaments, à des vitesses deux ou trois fois supérieures, les enroulements biconiques formés étant parfaitement réguliers.The device making the connection between the coil and the sine bar is not shown in the patent. Thanks to such an installation, it was possible to wind textile threads, filaments, at speeds two or three times higher, the biconical windings formed being perfectly regular.

Par rapport aux dispositifs antérieurs, un tel dispositif présente, outre la possibilité de bobiner des fils plats et d'augmenter les vitesses de production, les avantages suivants :

  • - réduction bruit de chocs,
  • - réduction puissance absorbée.
Compared to previous devices, such a device has, in addition to the possibility of winding flat wires and increasing production speeds, the following advantages:
  • - impact noise reduction,
  • - reduction in power consumption.

Il est bien évident que l'invention n'est pas limitée au mode de réalisation décrit précédemment, mais qu'elle en couvre également toutes les variantes.It is obvious that the invention is not limited to the embodiment described above, but that it also covers all the variants.

Ainsi, par exemple il pourrait être utilisé pour le 5 bobinage en tête individuel ou pour obtenir des enroulements à bords mous en accentuant l'accélération de pointe.Thus, for example, it could be used for individual head winding or for obtaining soft-edge windings by accentuating the peak acceleration.

De même, si dans la présente description, l'invention a été décrite avec une accélération du mouvement du guide- en fin de course, il est évident qu'en jouant sur la relation qui existe entre la forme de la came et la forme de la barre sinus, que l'on pourrait modifier le mouvement du guide-fil pour obtenir éventuellement soit une décélération, soit une vitesse constante.Similarly, if in the present description, the invention has been described with an acceleration of the movement of the guide - at the end of the race, it is obvious that by playing on the relationship which exists between the shape of the cam and the shape of the sine bar, that one could modify the movement of the wire guide to possibly obtain either a deceleration or a constant speed.
