Description

La présente invention a trait aux ratières du type rotatif pour la formation de la foule sur les métiers à tisser.The present invention relates to the dobbies of the rotary type for training the crowd on the looms.

On sait que dans les ratières rotatives le mouvement de lève et de baisse des cadres de lisses est assuré, non pas par des balances actionnées par des couteaux à déplacement alternatif, mais par des bielles commandées par des excentriques montés sur l'arbre principal de la mécanique. Cet arbre 'est animé d'un mouvement de rotation intermittent et lors de chaque arrêt, c'est-à-dire tous les demi-tours de l'arbre précité, le dispositif de lisage doit, au niveau de chacune des lames de la ratière (c'est-à-dire de l'ensemble d'actionnement associé à chaque cadre de lisses) et en fonction du dessin ou armure à obtenir sur le tissu en cours de tissage, solidariser l'excentrique soit avec ledit arbre pour commander la bielle, soit avec cette dernière afin d'opérer son immobilisation angulaire.We know that in rotary dobbies the lifting and lowering of heald frames is ensured, not by scales actuated by reciprocating knives, but by connecting rods controlled by eccentrics mounted on the main shaft of the mechanical. This shaft 'is driven by an intermittent rotational movement and at each stop, that is to say every half-turn of the aforementioned shaft, the reading device must, at the level of each of the blades of the dobby (that is to say the actuation assembly associated with each heald frame) and depending on the design or weave to be obtained on the fabric being woven, secure the eccentric either with said shaft to control the rod, either with the latter in order to operate its angular immobilization.

Dans les constructions classiques la solidarisation sélective sus-indiquée est généralement effectuée pour chaque lame à l'aide d'un système de crochet basculant porté par l'excentrique et agencé pour coopérer avec des empreintes respectivement ménagées dans l'arbre principal et dans la bielle. On conçoit qu'un tel système, amené à supporter des efforts très importants au cours du fonctionnement de la ratière et du métier, est d'accessibilité très réduite de par sa localisation ; cette difficulté d'accès complique aussi bien les opérations de maintenance et de réparation du système de crochet basculant que la commande de ce dernier par le dispositif de lisage.In conventional constructions, the aforementioned selective securing is generally carried out for each blade using a tilting hook system carried by the eccentric and arranged to cooperate with impressions formed respectively in the main shaft and in the connecting rod. . It is understandable that such a system, brought to bear very great efforts during the operation of the dobby and the loom, is of very limited accessibility due to its location; this difficulty of access complicates both the maintenance and repair operations of the tilting hook system as well as the control of the latter by the reading device.

Les perfectionnements qui font l'objet de la présente invention visent à remédier à cet inconvénient et à permettre la réalisation d'une ratière rotative de construction plus simple et de fiabilité accrue.The improvements which are the subject of the present invention aim to remedy this drawback and to allow the production of a rotary dobby of simpler construction and increased reliability.

L'invention consiste principalement à monter chaque crochet basculant de solidarisation sur une patte prévue sur l'excentrique correspondant pour déborder latéralement et radialement la périphérie de celui-ci qui est engagée dans l'ouverture de la bielle, et à faire coopérer ledit crochet avec des encoches pratiquées les unes dans la périphérie d'un entraîneur ou disque de grand diamètre solidaire de l'arbre à rotation intermittente, les autres dans un bossage annulaire latéral de la bielle.The invention mainly consists in mounting each tilting fastening hook on a lug provided on the corresponding eccentric to extend laterally and radially the periphery thereof which is engaged in the opening of the connecting rod, and in making said hook cooperate with notches made, one in the periphery of a large diameter drive or disc secured to the intermittently rotating shaft, the others in a lateral annular boss of the connecting rod.

Cette disposition particulière permet de loger le système de solidarisation sélective à une distance radiale relativement importante de l'arbre principal, ce qui facilite sa commande par le dispositif de lisage et les opérations de maintenance et de réparation, en même temps que cela réduit dans une mesure considérable les efforts appliqués audit système.This particular arrangement makes it possible to house the selective securing system at a relatively large radial distance from the main shaft, which facilitates its control by the reading device and the maintenance and repair operations, at the same time as this reduces in a measures the efforts applied to this system considerably.

On notera en outre que par suite du guidage latéral assuré par les différents disques ou entraîneurs, les paliers interposés entre l'arbre et chaque excentrique d'une part, et entre cet excentrique et l'ouverture de la bielle correspondante d'autre part, sont susceptibles d'être réalisés de manière très simplifiée et peu coûteuse, à l'aide de cages à rouleaux cylindriques prenant appui sur des chemins de roulement eux-mêmes cylindriques.It will also be noted that, as a result of the lateral guidance provided by the various discs or coaches, the bearings interposed between the shaft and each eccentric on the one hand, and between this eccentric and the opening of the corresponding connecting rod on the other hand, are capable of being produced in a very simplified and inexpensive manner, using cylindrical roller cages bearing on the raceways themselves cylindrical.

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 :

  • Figure 1 est une coupe transversale montrant l'agencement de l'une des lames d'une ratière rotative suivant l'invention.
  • Figure 2 reproduit fig. 1 après que l'arbre principal de la ratière se soit déplacé de 180°.
  • Figure 3 est une coupe longitudinale de la ratière, deux lames ayant été seulement représentées.
  • Figure 4 est une vue en perspective explosée faisant ressortir les pièces principales d'une lame de la ratière.
  • Figures 5 et 6 sont des vues en perspective par dessus montrant le crochet double de solidarisation à ses deux positions de fonctionnement.
The appended drawing, given by way of example, will allow a better understanding of the invention, the characteristics which it presents and the advantages which it is capable of providing:
  • Figure 1 is a cross section showing the arrangement of one of the blades of a rotary dobby according to the invention.
  • Figure 2 reproduced in fig. 1 after the main dobby shaft has moved 180 °.
  • Figure 3 is a longitudinal section of the dobby, two blades having only been shown.
  • Figure 4 is an exploded perspective view showing the main parts of a dobby blade.
  • Figures 5 and 6 are perspective views from above showing the double hook for securing in its two operating positions.

Sur ce dessin la référence 1 désigne la bielle d'actionnement de chacune des lames de la ratière, cette bielle comportant une perforation 10 (fig. 1, 2 et 3) pour son attelage par câble ou tringlerie avec le cadre de lisses correspondant. Comme plus particulièrement montré en fig. 4, à l'opposé de la perforation 10 chaque bielle 1 présente une ouverture 11 à grand diamètre, autour de laquelle est prévu concentriquement, sur l'un desdits côtés de la ladite bielle, un bossage annulaire ou collerette 12 ; la périphérie de cette collerette 12 est entaillée de deux encoches 13 diamétralement opposées l'une à l'autre.In this drawing, the reference 1 designates the actuating rod of each of the blades of the dobby, this rod comprising a perforation 10 (fig. 1, 2 and 3) for its coupling by cable or linkage with the corresponding heald frame. As more particularly shown in fig. 4, opposite the perforation 10 each connecting rod 1 has an opening 11 of large diameter, around which is provided concentrically, on one of said sides of said connecting rod, an annular boss or flange 12; the periphery of this collar 12 is notched with two notches 13 diametrically opposite one another.

A l'intérieur de l'ouverture 11 de chaque bielle 1 est engagé, avec interposition d'un roulement tel que celui référencé 3 en fig. 1 à 3, un excentrique 4 établi à une longueur axiale supérieure à celle de l'ouverture 11 de façon à déborder latéralement en dehors de celle-ci et à porter deux pattes radiales 40 et 41. L'ouverture excentrée 42 de l'excentrique 4 renferme, ici encore avec interposition d'un roulement 5, une pièce cylindrique 6. Les pièces 6 des différentes lames de la ratière sont assemblées axialement les unes aux autres par des tirants 7, l'ensemble 6-7 ainsi obtenu constituant l'arbre principal. Entre deux pièces 6 contiguës est intercalé un disque circulaire ou entraîneur 8 traversé par les tirants 7 de façon à se déplacer angulairement avec l'arbre 6-7 ; chaque entraîneur 8 est entaillé de deux encoches 80 diamétralement opposées l'une à l'autre.Inside the opening 11 of each connecting rod 1 is engaged, with the interposition of a bearing such as that referenced 3 in FIG. 1 to 3, an eccentric 4 established at an axial length greater than that of the opening 11 so as to project laterally outside of it and to carry two radial lugs 40 and 41. The eccentric opening 42 of the eccentric 4 contains, here again with the interposition of a bearing 5, a cylindrical part 6. The parts 6 of the different blades of the dobby are assembled axially to one another by tie rods 7, the assembly 6-7 thus obtained constituting the main tree. Between two contiguous parts 6 is interposed a circular disc or driver 8 crossed by the tie rods 7 so as to move angularly with the shaft 6-7; each coach 8 is notched with two notches 80 diametrically opposite one another.

La patte 40 de chaque excentrique 4 est percée afin de recevoir un axe 43 (fig. 1 et 2) formant support pour un crochet basculant 44. Ce dernier est prévu sous forme double et présente à ses extrémités deux becs 45 et 46 ; par ailleurs il est cintré transversalement de façon à ce que le bec 45 se trouve situé au niveau de la collerette 12 tandis que le bec 46 est disposé en vis-à-vis du disque ou entraîneur 8 correspondant, le tout comme montré en fig. 5 et 6. Il convient d'observer que le crochet 44 est soumis à l'action permanente d'un ressort de rappel 47 interposé entre la patte 42 de l'excentrique 4 et l'extrémité dudit crochet qui porte le bec 46.The tab 40 of each eccentric 4 is pierced in order to receive an axis 43 (fig. 1 and 2) forming a support for a tilting hook 44. The latter is provided in double form and has at its ends two nozzles 45 and 46; moreover it is bent transversely so that the spout 45 is located at the flange 12 while the spout 46 is disposed opposite the corresponding disc or driver 8, all as shown in FIG. 5 and 6. It should be observed that the hook 44 is subjected to the permanent action of a return spring 47 interposed between the tab 42 of the eccentric 4 and the end of said hook which carries the spout 46.

On notera également que les entraîneurs 8 présentent un diamètre extérieur au moins égal à celui de la collerette 12 afin d'embrasser latéralement les roulements 3 et 5.It will also be noted that the coaches 8 have an outside diameter at least equal to that of the flange 12 in order to laterally embrace the bearings 3 and 5.

Le fonctionnement général de la ratière découle des explications qui précèdent et se comprend aisément.The general functioning of the dobby follows from the foregoing explanations and is easily understood.

La rotation intermittente de l'arbre 6-7 est programmée de façon à ce que lors de chaque période d'arrêt tous les crochets 44 de la ratière se trouvent positionnés en vis-à-vis de l'un ou de l'autre de deux postes de commande, référencés 9 en fig. 1 et 2 et diamétralement opposés l'un à l'autre par rapport à l'arbre principal 6 ou 7. Chacun de ces postes 9 comprend un nombre d'organes d'actionnement égal à celui des lames de la ratière, chaque organe étant agencé pour faire basculer, sous l'effet du dispositif de lisage de la ratière, le crochet double 44 à l'encontre de son ressort de rappel 47 ; sur le dessin on a figuré cet organe sous la forme d'un bras coudé pivotant 90, attelé au dispositif de lisage par une biellette 91 à mouvement alternatif.The intermittent rotation of the shaft 6-7 is programmed so that during each stopping period all the hooks 44 of the dobby are positioned facing one or the other of the two control stations, referenced 9 in fig. 1 and 2 and diametrically opposite to each other with respect to the main shaft 6 or 7. Each of these stations 9 comprises a number of actuating members equal to that of the blades of the dobby, each member being arranged to tilt, under the effect of the dobby reading device, the double hook 44 against its return spring 47; in the drawing, this member has been shown in the form of a pivoted bent arm 90, coupled to the reading device by a rod 91 with reciprocating movement.

En fig. 1 on a supposé que sous l'effet du dispositif de lisage la biellette 91 s'était déplacée suivant la flèche F1 de telle sorte que l'extrémité du bras coudé 90 du poste supérieur 9 se trouve éloignée du crochet 44 envisagé ; le ressort 47 engage donc le bec 46 dans l'une des deux encoches 80 de l'entraîneur 8. Dans ces conditions, lorsque l'arbre 6-7 se remet à tourner avec l'entraîneur 8, l'excentrique 4 est obligé de se déplacer angulairement avec ledit arbre, ce qui a pour effet d'animer la bielle correspondante d'un mouvement qui provoque la levée du cadre correspondant. On notera que dès le début de la rotation de l'excentrique 4 le bec 45 du crochet 44 glisse le long de la périphérie de la collerette 12 qui s'oppose à tout dégagement intempestif du bec 46 par basculement inopiné du crochet à l'encontre du ressort de rappel 47.In fig. 1 it was assumed that under the effect of the reading device the rod 91 had moved along the arrow F1 so that the end of the bent arm 90 of the upper station 9 is distant from the hook 44 envisaged; the spring 47 therefore engages the spout 46 in one of the two notches 80 of the coach 8. Under these conditions, when the shaft 6-7 starts to rotate again with the coach 8, the eccentric 4 is forced to move angularly with said shaft, which has the effect of animating the corresponding connecting rod with a movement which causes the lifting of the corresponding frame. Note that from the start of the rotation of the eccentric 4 the spout 45 of the hook 44 slides along the periphery of the flange 12 which prevents any untimely release of the spout 46 by unexpected tilting of the hook against return spring 47.

Le crochet 44 vient en tout état de cause s'arrêter en vis-à-vis du poste 9 opposé (fig. 2). Si le dispositif de lisage a actionné le bras coudé 90 de ce poste pour que le crochet 44 reste libre, sous l'action du ressort 47, de maintenir le bec 46 dans l'encoche 80, la bielle va effectuer une nouvelle oscillation sous l'effet de la rotation de l'excentrique 4, en provoquant la descente du cadre de lisses qui lui est associé. Si au contraire et ainsi qu'on l'a supposé en fig. 2 le dispositif de lisage commande le bras 91 du poste inférieur 9 suivant la flèche F2, le crochet 44 bascule et son bec 45 vient s'engager dans l'encoche correspondante 13 de la collerette 12 de la bielle, encoche qui se trouve disposée en vis-à-vis du bec précité par suite du décalage angulaire ménagé entre les paires d'encoches 80-80 et 13-13 (ce décalage étant égal à l'amplitude angulaire définie par les deux becs 45 et 46 de chaque crochet double 44). L'excentrique 4 reste immobile angulairement et à travers le crochet 44 assure la retenue angulaire de la bielle 1 qui ne peut donc se déplacer intempestivement sous l'effet du poids du cadre de lisses.The hook 44 comes in any event to stop opposite the opposite station 9 (fig. 2). If the reading device actuated the bent arm 90 of this station so that the hook 44 remains free, under the action of the spring 47, to keep the spout 46 in the notch 80, the connecting rod will perform a new oscillation under the 'effect of the rotation of the eccentric 4, causing the descent of the heald frame associated with it. If on the contrary and as it was supposed in fig. 2 the reading device controls the arm 91 of the lower station 9 along the arrow F2, the hook 44 switches and its beak 45 engages in the corresponding notch 13 in the flange 12 of the connecting rod, a notch which is arranged in with respect to the aforementioned spout as a result of the angular offset formed between the pairs of notches 80-80 and 13-13 (this offset being equal to the angular amplitude defined by the two spouts 45 and 46 of each double hook 44 ). The eccentric 4 remains angularly stationary and through the hook 44 ensures the angular retention of the connecting rod 1 which cannot therefore inadvertently move under the effect of the weight of the heald frame.

On notera ici encore qu'une fois le bec 45 engagé dans l'encoche 13 sous l'effet du bras coudé 90, le crochet 44 ne peut basculer sous l'effet du ressort 47 par suite du contact glissant du bec 46 contre la périphérie de l'entraîneur 8, et ce jusqu'à ce que ce dernier vienne présenter à nouveau une encoche 80 en vis-à-vis dudit bec 46.It will be noted here again that once the spout 45 engaged in the notch 13 under the effect of the bent arm 90, the hook 44 cannot tilt under the effect of the spring 47 as a result of the sliding contact of the spout 46 against the periphery of the trainer 8, and this until the latter comes again to present a notch 80 facing said spout 46.

On comprend que la construction ci-dessus exposée est particulièrement robuste, du fait notamment de ce que le système de solidarisation sélective constitué par le crochet double 44 agit au niveau de la périphérie de chaque entraîneur 8, c'est-à-dire à une distance radiale relativement importante de l'arbre principal 6-7 ; l'effort tangentiel transmis est en conséquence moins important que lorsque la solidarisation est effectuée au niveau de l'arbre. De plus l'accessibilité est considérablement améliorée du fait que les crochets basculants 44 se trouvent disposés à l'extérieur des excentriques.It is understood that the above-described construction is particularly robust, in particular due to the fact that the selective joining system constituted by the double hook 44 acts at the periphery of each coach 8, that is to say at a relatively large radial distance from main shaft 6-7; the tangential force transmitted is consequently less important than when the joining is carried out at the level of the tree. In addition, accessibility is considerably improved because the tilting hooks 44 are arranged outside the eccentrics.

On notera encore et ainsi qu'on la souligné plus haut que les roulements intermédiaires 3 et 5 peuvent présenter une construction très simplifiée par suite de la retenue latérale opérée par les entraîneurs 8.It will also be noted, and as has been pointed out above, that the intermediate bearings 3 and 5 may have a very simplified construction owing to the lateral restraint operated by the coaches 8.

Il doit d'ailleurs être entendu que la description qui précède n'a été donnée qu'à titre d'exemple et qu'elle ne limite nullement le domaine revendiqué dont on ne sortirait pas en remplaçant les détails d'exécution décrits par tous autres équ iva- lents. On conçoit notamment que les postes 9 soient susceptibles de formes de réalisation multiples (commande mécanique par dessin-planchette ou par papier perforé, commande électromagnétique, commande électronique, etc...) ; il va en outre de soi que ces postes 9 peuvent être agencés afin d'assurer une commande positive des crochets doubles 44 dans les deux sens de basculement, en doublant ainsi dans un sers l'action des ressorts de rappel 47 ou même en permettant de se dispenser de ces derniers.It should moreover be understood that the foregoing description has been given only by way of example and that it in no way limits the area claimed from which one would not depart by replacing the execution details described by all other equiva- lent. It is understood in particular that the stations 9 are capable of multiple embodiments (mechanical control by drawing board or by perforated paper, electromagnetic control, electronic control, etc.); it also goes without saying that these stations 9 can be arranged in order to ensure positive control of the double hooks 44 in the two directions of tilting, thereby doubling in one action the action of the return springs 47 or even making it possible to dispense with these.
