The lower end of each coil is engaged in a disc 10 which carries a hook. This hook disc rotates with the spool and the hook is intended to grip the wire at the time of transfer as will be seen below.
- the shafts of the coil supports 7 and 8 are free at their upper end, so that the coils can be put in place by vertical movement from top to bottom and subsequent locking.
- pulleys 11 integral with the trees. Two motors 12 supported by the base 3 make it possible to drive the reel supports by means of the belts 13.
- the transfer device 14 comprises a horizontal arm 15 constituted in the form of an elongated box of rectangular section and a vertical upright 16.
- the box 15 is located at the upper part of the winder and extends over the reel supports. It is secured to a bracket 6 and a tubular shaft 5 engaged in an opening of the bracket 4 and the base 35 of the frame 1.
- the transfer device is guided so as to be p ter around ivo- a vertical central axis.
- the upright 16 As for the upright 16, it also has a rectangular profile. It is rigidly connected to the horizontal arm 15 at its end opposite the shaft 5 and, by means of a fork 17 on which a roller 18 rotates, it rests on the base plate 2.
- the transfer device 14 can perform pivoting movements around the axis of its vertical shaft, the roller 18 performing a stroke in an arc of a circle on the base plate 2.
- the control of this movement is carried out at by means of a jack 36 which comprises a cylinder 36a connected by a hinge 37 to a base 38 fixed to the console 4 and a rod 39 whose the end is articulated to an element integral with the box 15.
- a cutting trolley 19 capable of sliding vertically from top to bottom and from bottom to top in the upright 16. This cutting trolley is driven by belt and in. pourer by the motor 23 of a pulling device housed in the box 15.
- the cutting trolley 19 carries a set of pulleys comprising two pulleys 20 and 21 with parallel axes. These axes are arranged vertically and the cheeks of the pulleys pass immediately close to one another.
- a third pulley 22 rotates on a horizontal axis on the cutting trolley. The median plane of its groove is coincident with the plane of symmetry tangent simultaneously to the two pulleys 20 and 21.
- the box 15 constituting the upper horizontal arm of the transfer device serves as a housing for a withdrawer composed of the motor 23 and two pulleys 24 and 25, and to an accumulator composed of pulleys 26 and 27.
- This ci is equipped with known type adjustment means. It perceives the variations in speed of the coil and sends an adjustment signal to its drive motor.

- the bars 32 extend in a horizontal overhang and their free ends are slightly bent towards the outside as seen in fig. 1.
- the transfer device is placed between the reel supports and directed perpendicular to the vertical plane defined by the axes of the reel supports.
- the toothed wheel 30 meshes with a pinion 33 secured to the tubular shaft 5.
- the gear ratios are chosen so that the angle of rotation of the deflection device is in a predetermined ratio with the pivot angle of the transfer device .
- the transfer device 14 is in an extreme position on the reel in operation (Fig. 1).
- the two bars 32 of the deflector device are then in a horizontal plane situated slightly below the level of the lower cheeks of the coils 9.
- the wire B coming from a source which it is not necessary to specify, is guided by so as to arrive on the machine in the axis of the tubular upright 5. It passes into the withdrawer 24-25 and into the accumulator 26-27 which makes it possible to compensate for momentary variations in speed during the winding then on a return pulley 34 located at the top of the upright 16 and comes on the cutting carriage 19. It passes between the two tangent pulleys 20 and 21 which guide it towards one of the two coils 9 on which it is wound. When this reel is full, the transfer device is moved to the other empty reel.
- This pivoting movement causes a rotation of the deflector device which takes the position shown in FIG. 3.
- the displacement described takes place while the cutting trolley is in its lower position, so that the wire follows a trajectory comprising a double bend as seen in FIG. 3. It can be seen that the wire passes over the edge of the disc 10 associated with the empty spool, so that the hook associated with this disc can grip it, which initiates winding on this spool.
- the transfer device is then in the position visible in FIG. 1.
- the movement of the transfer device is greatly facilitated by the fact that its amount 16 rests on the base plate 2 via the roller 18. Instead of a roller, it could also, if necessary, provide a support for skate.
Abstract
Description
La présente invention a pour objet un bobinoir double à fonctionnement continu comportant un bâti, deux supports de bobine d'axes parallèles montés rotativement sur le bâti, un dispositif de transfert capable de pivoter autour d'un axe central parallèle aux axes des bobines et équipé de deux organes de guidage du fil dont les axes sont également parallèles à ceux des bobines et entre lesquels le fil est engagé, et un dispositif de trancanage associé au dispositif de transfert.The present invention relates to a double winder with continuous operation comprising a frame, two reel supports of parallel axes rotatably mounted on the frame, a transfer device capable of pivoting around a central axis parallel to the axes of the reels and equipped two wire guide members whose axes are also parallel to those of the coils and between which the wire is engaged, and a cutting device associated with the transfer device.
La demande de brevet européen 0003385, ainsi que la demande de brevet allemand DOS 23 04 483 décrivent des bobinoirs doubles de ce genre. La réalisation d'un dis - positif de transfert dont le support est capable de basculer autour d'un axe central parallèle aux axes des bobines entraîne une certaine simplification constructive par rapport aux bobinoirs connus dans lesquels le dispositif de transfert est monté sur un chariot. L'encombrement du bobinoir est réduit et certaines de ses parties sont allégées, ce qui est spécialement avantageux avec les bobinoirs fonctionnant à grande vitesse comme les bobinoirs pour fils téléphoniques ou fils émaillés destinés aux enroulements électro-magnétiques.European patent application 0003385, as well as German patent application DOS 23 04 483 describe double winders of this kind. The production of a transfer device, the support of which is capable of tilting about a central axis parallel to the axes of the coils, leads to a certain constructive simplification compared with known winders in which the transfer device is mounted on a carriage. The size of the winder is reduced and some of its parts are lightened, which is especially advantageous with winders operating at high speed such as winders for telephone wires or enameled wires intended for electromagnetic windings.
La présente invention vise à améliorer les qualités de ces bobinoirs connus en réduisant encore leur encombrement tout en assurant la fiabilité et la sécurité du fonctionnement à grande vitesse.The present invention aims to improve the qualities of these known winders by further reducing their size. while ensuring the reliability and safety of high speed operation.
Ce résultat est obtenu par le fait que, selon l'invention, .le bobinoir double, du type défini ci-dessus, est caractérisé en ce que les dits axes parallèles sont verticaux, en ce que le dispositif de transfert pivotant comporte un support rigide formé d'un bras horizontal dont une extrémité est liée à un organe de pivotement, etd'un montant vertical, en ce que le bâti comporte une plaque de base sur laquelle ledit montant vertical repose par l'intermédiaire d'un patin ou d'un galet de façon à parcourir une course en arc de cercle sur ladite plaque de base lors du pivotement du dispositif de transfert.This result is obtained by the fact that, according to the invention, the double winder, of the type defined above, is characterized in that the said parallel axes are vertical, in that the pivoting transfer device comprises a rigid support formed of a horizontal arm, one end of which is linked to a pivoting member, and of a vertical upright, in that the frame comprises a base plate on which said vertical upright rests by means of a pad or a roller so as to travel a stroke in an arc of a circle on said base plate during the pivoting of the transfer device.
On s'est aperçu, en effet, qu'en renversant la disposition usuelle des bobinoirs du type considéré ici, afin que les axes des bobines et la course du dispositif de trancanage soient orientés verticalement, diverses simplifications constructives pouvaient être introduires, qui tendaient au but défini ci-dessus.It has been found, in fact, that by reversing the usual arrangement of winders of the type considered here, so that the axes of the reels and the travel of the cutting device are oriented vertically, various constructive simplifications could be introduced, which tended to purpose defined above.
On va décrire ci-après, à titre d'exemple, une forme d'exécution de l'objet de l'invention, en se référant au dessin annexé dont:
- la fig. 1 est une vue en plan de dessus, dans une position de transfert,
- la fig. 2 une vue en élévation montrant le bobinoir dans une position de bobinage, et
- la fig. 3 une vue en élévation partielle dans le sens de la flèche A à la fig. 1, montrant le déviateur en position de transfert.
- fig. 1 is a top plan view, in a transfer position,
- fig. 2 is an elevation view showing the winder in a winding position, and
- fig. 3 a partial elevational view in the direction of arrow A in FIG. 1, showing the diverter in the transfer position.
Le bâti 1 du bobinoir représenté au dessin comporte une plaque de base 2 sur laquelle sont fixés un socle 3 destiné à recevoir des supports de bobines, une console centrale 4 qui porte le dispositif déviateur et un tourillon vertical 35 pourvu d'une embase et destiné à supporter et guider le dispositif de transfert.The
Deux supports de bobines 7 et 8 sont montés sur le socle 3, leurs axes étant parallèles et verticaux. Chacun d'eux comporte un arbre (non représenté) destiné à recevoir l'une des deux bobines 9. L'extrémité inférieure de chaque bobine est engagée dans un disque 10 qui porte un crochet. Ce disque à crochet tourne avec la bobine et le crochet est destiné à saisir le fil au moment du transfert comme on le verra plus loin. Les arbres des supports de bobines 7 et 8 sont libres à leur extrémité supérieure, de sorte que les bobines peuvent être mises en place par déplacement vertical de haut en bas et verrouillage ultérieur. A l'intérieur du socle 3 sont disposées des poulies 11 solidaires des arbres. Deux moteurs 12 supportés par le socle 3 permettent d'entraîner les supports de bobines par l'intermédiaire des courroies 13.Two coil supports 7 and 8 are mounted on the
Le dispositif de transfert 14 comporte un bras horizontal 15 constitué sous forme d'un caisson allongé de section rectangulaire et un montant vertical 16. Le caisson 15 est situé à la partie supérieure du bobinoir et s'étend par dessus les supports de bobines. Il est solidaire d'une console 6 et d'un arbre tubulaire 5 engagé dans une ouverture de la console 4 et sur l'embase 35 du bâti 1. Ainsi, le dispositif de transfert est guidé de façon à pouvoir pivo- ter autour d'un axe central vertical.The
Quant au montant 16, il présente également un profil rectangulaire. Il est lié rigidement au bras horizontal 15 à son extrémité opposée à l'arbre 5 et, par l'intermédiaire d'une fourche 17 sur laquelle tourne un galet 18 il repose.sur la plaque de base 2. On se rend compte que, de cette façon, le dispositif de transfert 14 peut effectuer des mouvements de pivotement autour de l'axe de son arbre vertical, le galet 18 effectuant une course en arc de cercle sur la plaque de base 2. La commande de ce déplacement est réalisée au moyen d'un vérin 36 qui comporte un cylindre 36a relié par une articulation 37 à un socle 38 fixé à la console 4 et une tige 39 dont l'extrémité est articulée à un élément solidaire du caisson 15.As for the upright 16, it also has a rectangular profile. It is rigidly connected to the
A l'intérieur du montant 16 est disposé un chariot de trancanage 19 capable de coulisser verticalement de haut en bas et de bas en haut dans le montant 16. Ce chariot de trancanage est entraîné par courroie et in- . verseur par le moteur 23 d'un dispositif de tirage logé dans le caisson 15.Inside the upright 16 is disposed a
Le chariot de trancanage 19 porte un ensemble de poulies comprenant deux poulies 20 et 21 d'axes parallèles. Ces axes sont disposés verticalement et les joues des poulies passent immédiatement à proximité l'une de l'autre. Une troisième poulie 22 tourne sur un axe horizontal sur le chariot de trancanage. Le plan médian de sa gorge est confondu avec le plan de symétrie tangent simultanément aux deux poulies 20 et 21.The
Comme on le voit au dessin, le caisson 15 constituant le bras horizontal supérieur du dispositif de transfert sert de logement à un retireur composé du moteur 23 et de deux poulies 24 et 25, et à un accumulateur composé de poulies 26 et 27. Celui-ci est équipé de moyens de réglage de type connu. Il perçoit les variations de vitesse de la bobine et envoie un signal de réglage sur son moteur d'entraînement, La translation des poulies 27 est assurée par une glissière 40. Un câble et des poids ( non représentés) permettent de donner la tension nécessaire au fil.As can be seen in the drawing, the
Le bobinoir décrit comporte finalement un dispositif déviateur désigné de façon générale par 28. Ce dispositif est supporté par la console 4. Il comporte un arbre horizontal 29 à une extrémité duquel est fixée une roue dentée 30 tandis qu'à son autre extrémité est monté un socle en forme de disque circulaire 31 qui porte deux barres 32 parallèles à l'axe de l'arbre 29 et placées dans des positions diamétralement opposées sur le socle 31. Les barres 32 s'étendent en porte-à-faux horizontalement et leurs extrémités libres sont légèrement coudées vers l'extérieur comme on le voit à la fig. 1. Le dispositif de transfert est placé entre les supports de bobines et dirigé perpendiculairement au plan vertical défini par les axes des supports de bobines. La roue dentée 30 engrène avec un pignon 33 solidaire de l'arbre tubulaire 5. Les rapports d'engrenage sont choisis de façon que l'angle de rotation du dispositif déviateur soit dans un rapport prédéterminé avec l'angle de pivotement du dispositif de transfert.The winder described finally comprises a deflection device generally designated by 28. This device is supported by the console 4. It comprises a
Pendant l'opération de bobinage, le dispositif de transfert 14 se trouve dans une position extrême sur la bobine.en travail (Fig. 1). Les deux barres 32 du dispositif déviateur se trouvent alors dans un plan horizontal situé légèrement en-dessous du niveau des joues inférieures des bobines 9. Le fil B provenant d'une source qu'il n'est pas nécessaire de préciser, est guidé de façon à arriver sur la.machine dans l'axe du montant tubulaire 5. Il passe dans le retireur 24-25 et dans l'accumulateur 26-27 qui permet de compenser des variations de vitesse momentanées pendant le bobinage puis sur une poulie de renvoi 34 située au sommet du montant 16 et vient sur le chariot de trancanage 19. Il passe entre les deux poulies tangentes 20 et 21 qui le guident vers l'une des deux bobines 9 sur laquelle il s'enroule. Lorsque cette bobine est pleine, le dispositif de transfert est déplacé vers l'autre bobine qui est vide.During the winding operation, the
Ce mouvement de pivotement entraîne une rotation du dispositif déviateur qui prend la position représentée à la fig. 3. Le déplacement décrit s'effectue alors que le chariot de trancanage est dans sa position inférieure, de sorte que le fil suit une trajectoire comportant un double coude tel qu'on la voit à la fig. 3. On voit que le fil passe sur le bord du disque 10 associé à la bobine vide, de sorte que le crochet associé à ce disque peut le saisir, ce qui amorce le bobinage sur cette bobine. Le dispositif de transfert est alors dans la position visible à la fig. 1.This pivoting movement causes a rotation of the deflector device which takes the position shown in FIG. 3. The displacement described takes place while the cutting trolley is in its lower position, so that the wire follows a trajectory comprising a double bend as seen in FIG. 3. It can be seen that the wire passes over the edge of the
Le déplacement du dispositif de transfert est grandement facilité par le fait que son montant 16 repose sur la plaque de base 2 par l'intermédiaire du galet 18. Au lieu d'un galet, on pourrait également, le cas échéant, prévoir un support à patin.The movement of the transfer device is greatly facilitated by the fact that its
