Description

La présente invention a trait aux mécaniques pour la formation de la foule sur les machines à tisser, le terme "mécaniques" englobant aussi bien les ratières dont le programme d'armure est susceptible d'être aisément modifié, que les mécanismes simplifiés à cames ou similaires, purement répétitifs.The present invention relates to mechanics for forming the crowd on weaving machines, the term "mechanical" including both the dobbies whose armor program is likely to be easily modified, as the simplified mechanisms with cams or similar, purely repetitive.

On sait que pour la manoeuvre individuelle des différents cadres de lisses montés sur le métier, ces mécaniques d'armure comprennent un nombre égal d'ensembles d'actionnement (ensembles généralement désignés sous le nom de "lames") qui sont disposés parallèlement les uns aux autres et dont chacun est formé par une série d'organes oscillants qui coopèrent les uns avec les autres en vue de fournir, au moment opportun qui est fonction de l'armure désirée pour le tissu à réaliser, l'effort nécessaire au déplacement vertical du cadre de lisses correspondant. La nature et la forme de ces organes oscillants varient suivant les différents types de mécaniques, mais on peut retenir qu'il s'agit le plus souvent de leviers, de bielles ou biellettes, de crochets, de porte-galets, etc... animés d'un mouvement angulaire d'une amplitude définie. Bien entendu les organes oscillants identiques des différentes lames sont montés sur un axe-support commun fixé dans le bâti.It is known that for the individual operation of the different heald frames mounted on the loom, these armor mechanics comprise an equal number of actuating assemblies (assemblies generally designated by the name of "blades") which are arranged in parallel to the others and each of which is formed by a series of oscillating members which cooperate with each other in order to provide, at the appropriate time which is a function of the weave desired for the fabric to be produced, the force necessary for the vertical displacement the corresponding heald frame. The nature and shape of these oscillating members vary according to the different types of mechanical, but it can be remembered that they are most often levers, connecting rods or rods, hooks, roller carriers, etc. animated by an angular movement of a defined amplitude. Of course, the identical oscillating members of the different blades are mounted on a common support pin fixed in the frame.

Certains de ces organes oscillants, notamment les crochets de retenue et les leviers de tirage attelés aux cadres de lisses, sont soumis à des efforts élevés, si bien qu'en vue d'éviter tout fléchissement des axes-supports communs, il est nécessaire d'avoir recours à des pièces résistantes de fort diamètre, dont l'encombrement gêne en fait l'implantation dans le bâti, toujours assez exigu, de la mécanique.Some of these oscillating members, in particular the retaining hooks and the pulling levers coupled to the heald frames, are subjected to high forces, so that in order to avoid any deflection of the common support axes, it is necessary to '' have recourse to resistant parts of large diameter, whose bulk hinders in fact the installation in the frame, always quite cramped, of the mechanics.

En pratique, on a proposé différents modes de montage des organes oscillants sur l'axe-support commun, modes dont les trois principaux ont été schématiquement illustrés aux fig. 1 à 3 du dessin annexé aux présentes.In practice, various methods of mounting the oscillating members on the common support axis have been proposed, modes of which the three main ones have been schematically illustrated in FIGS. 1 to 3 of the drawing appended hereto.

Le montage le plus simple est celui suivant fig. 1, dans lequel l'axe fixe 1 supporte directement les organes oscillants 2, disposés côte à côte sans aucune séparation. Dans ces conditions, il est clair que ces organes 2 frottent les uns contre les autres, les frictions ainsi engendrées provoquant des échauffements, une usure sensible et l'apparition de fautes de tissage.The simplest assembly is that according to fig. 1, in which the fixed axis 1 directly supports the oscillating members 2, arranged side by side without any separation. Under these conditions, it is clear that these members 2 rub against each other, the friction thus generated causing overheating, significant wear and the appearance of weaving faults.

Aussi a-t-on proposé le montage individualisé suivant fig. 2, dans lequel les organes 2, toujours directement engagés sur l'axe commun 1, sont séparés les uns des autres par des joncs fendus ou circlips 3, retenus dans des rainures 1a usinées dans la paroi de l'axe. On évite ainsi le frottement mutuel des organes 2, mais la réalisation des rainures 1a et le montage des circlips 3 et des organes 2 eux-mêmes augmentent sensiblement le prix de revient, en même temps que les rainures 1a affaiblissent de manière non négligeable la résistance de l'axe 1 à la flexion.So we proposed the individualized assembly according to fig. 2, in which the members 2, still directly engaged on the common axis 1, are separated from each other by split rods or circlips 3, retained in grooves 1 a machined in the wall of the axis. This prevents mutual friction members 2, but the realization of the grooves 1a and mounting circlips 3 and the elements 2 themselves significantly increase the cost, along with the grooves 1 a weakening in no small way the resistance of axis 1 to bending.

Pour éviter ces inconvénients, on a eu recours à la solution illustrée en fig. 3, dans laquelle l'individualisation des organes oscillants 2 est assurée à l'aide de bagues épaulées 4 interposées entre l'axesupport 1 et le moyeu de chaque organe. Le montage est simplifié et l'axe 1 conserve sa pleine résistance, mais par contre les bagues 4 doivent être réalisées dans des métaux ou alliage spéciaux, donc coûteux, pour résister au frottement. Par ailleurs et surtout, le diamètre de frottement est accru et pour éviter le mauvais rendement ainsi introduit dans la mécanique, il y a lieu de diminuer le diamètre de l'axe 1 en réduisant ainsi sa résistance à la flexion.To avoid these drawbacks, the solution illustrated in FIG. 3, in which the individualization of the oscillating members 2 is ensured by means of shouldered rings 4 interposed between the axle 1 and the hub of each member. The assembly is simplified and the axis 1 retains its full strength, but on the other hand the rings 4 must be made of special metals or alloy, therefore expensive, to resist friction. Furthermore and above all, the friction diameter is increased and to avoid the poor efficiency thus introduced into the mechanics, it is necessary to reduce the diameter of the axis 1 thereby reducing its resistance to bending.

C'est à ces inconvénients qu'entend remédier la présente invention, et ce à l'aide d'une solution qui permet au moyeu des organes oscillants de frotter directement sur un arbre à paroi lisse, ainsi dépourvu de toute rainure, et qui néanmoins assure l'individualisation desdits organes en vue d'interdire toute friction latérale mutuelle de ceux-ci.It is to these drawbacks that the present invention intends to remedy, and this by means of a solution which allows the hub of the oscillating members to rub directly on a shaft with a smooth wall, thus devoid of any groove, and which nevertheless ensures the individualization of said organs with a view to prohibiting any mutual lateral friction between them.

L'invention a pour objet la mécanique d'armure qui est définie à la revendication 1.The subject of the invention is the armor mechanics which is defined in claim 1.

En fait l'invention consiste essentiellement à opérer la séparation des organes oscillants contigus à l'aide d'entretoises annulaires qui sont engagées sur l'axe-support entre lesdits organes et qui comportent, sur l'une au moins de leurs faces latérales, des bossages en saillie propres à venir en contact avec l'entretoise adjacente en définissant entre ces deux entretoises un espace libre suffisant pour le montage oscillant d'un organe.In fact, the invention essentially consists in operating the separation of the adjoining oscillating members using annular spacers which are engaged on the support axis between said members and which comprise, on at least one of their lateral faces, projecting bosses capable of coming into contact with the adjacent spacer, defining between these two spacers a sufficient free space for the oscillating mounting of a member.

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 :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:

Comme indiqué plus haut, fig. 1 à 3 sont des coupes schématiques illustrant trois solutions antérieures.As indicated above, fig. 1 to 3 are schematic sections illustrating three previous solutions.

Fig. 4 est une vue en perspective de l'une des entretoises intermédiaires d'individualisation d'une mécanique d'armure établie suivant la présente invention.Fig. 4 is a perspective view of one of the intermediate spacers for individualizing an armor mechanism established according to the present invention.

Fig. 5 est une coupe transversale montrant le montage d'un organe oscillant entre deux entretoises suivant fig. 4.Fig. 5 is a cross section showing the mounting of an oscillating member between two spacers according to FIG. 4.

Fig. 6 est une coupe partielle suivant le plan indiqué en VI-VI en fig. 5.Fig. 6 is a partial section along the plane indicated in VI-VI in FIG. 5.

En fig. 4, on a représenté en 5 une entretoise qui est percée d'une ouverture 5a formant moyeu, une saillie annulaire 5b étant avantageusement prévue sur chacune des faces latérales de ladite entretoise autour du débouché de cette ouverture 5a. L'entretoise 5 est solidaire d'un prolongement 6 en forme de bras qui est percé en 6a à un diamètre nettement inférieur à celui de l'ouverture 5a, ce perçage 6a étant de la même manière bordé par deux saillies annulaires opposées 6b.In fig. 4, there is shown at 5 a spacer which is pierced with an opening 5 a forming a hub, an annular projection 5 b being advantageously provided on each of the lateral faces of said spacer around the outlet of this opening 5 a . The spacer 5 is integral with an extension 6 in the form of an arm which is drilled at 6 a at a diameter much smaller than that of the opening 5 a , this hole 6 a being similarly bordered by two opposite annular projections 6 b .

Sur la pièce 5-6 ainsi profilée, on a prévu une série de bossages 7 qui débordent latéralement sur l'une et l'autre des faces opposées de ladite pièce. Dans l'exemple de réalisation envisagé, on a supposé que l'entretoise 5 présentait quatre bossages débordants 7 tandis que le bras 6 n'en portait qu'un seul.On the part 5-6 thus profiled, a series of bosses 7 are provided which protrude laterally on one and the other of the opposite faces of said part. In the exemplary embodiment envisaged, it has been assumed that the spacer 5 had four protruding bosses 7 while the arm 6 carried only one.

Fig. 5 et 6 illustrent bien le montage des pièces 5-6 et des organes oscillants 2 sur l'axe-support commun 1. Dans le cas envisagé, les organes 2 sont constitués par des crochets qui sous l'action du dispositif de lisage de la mécanique (action qui a été figurée sous la forme de flèches opposées f), sont destinés à venir s'atteler avec des crochets fixes 8 correspondants, ou à échapper à ces derniers, et ce moyennant une oscillation d'amplitude angulaire réduite.Fig. 5 and 6 illustrate the mounting of parts 5-6 and of the oscillating members 2 on the common support axis 1. In the case envisaged, the members 2 are constituted by hooks which under the action of the reading device of the mechanical (action which has been represented in the form of opposite arrows f ), are intended to come to be coupled with fixed hooks 8 corresponding, or to escape these, and this by means of an oscillation of reduced angular amplitude.

Entre deux organes ou crochets 2 adjacents est interposée une pièce 5-6 dont le bras 6 est engagé par son perçage 6a sur une tige 9 fixée dans le bâti de la mécanique en étant orientée parallèlement à l'axe 1, la position de cette tige 9 étant telle que l'ensemble des entretoises 5 est retenu angulairement de façon à ce que la partie principale des crochets 2 et leur queue d'actionnement 2a se trouvent disposées entre les bossages 7, en jouissant d'une liberté angulaire suffisante pour leur oscillation. Les bossages 7 de deux pièces 5-6 contiguës peuvent de ce fait venir en butée, en assurant l'espacement correct des crochets 2.Between two adjacent members or hooks 2 is interposed a part 5-6, the arm 6 of which is engaged by its bore 6 a on a rod 9 fixed in the mechanical frame while being oriented parallel to the axis 1, the position of this rod 9 being such that all of the spacers 5 are angularly retained so that the main part of the hooks 2 and their actuating tail 2 a are disposed between the bosses 7, enjoying sufficient angular freedom for their oscillation. The bosses 7 of two contiguous pieces 5-6 can therefore come into abutment, ensuring the correct spacing of the hooks 2.

Chaque organe oscillant ou crochet 2 frotte directement sur l'axe-support 1 prévu à paroi lisse. Le montage de ces crochets et des pièces 5-6 sur cet axe 1 ne présente aucune difficulté et peut être effectué à l'aide de machines automatiques simples, à haut rendement.Each oscillating member or hook 2 rubs directly on the support axis 1 provided with a smooth wall. The mounting of these hooks and parts 5-6 on this axis 1 presents no difficulty and can be carried out using simple automatic machines, with high efficiency.

Le nombre des bossages 7, leur disposition et leur profil en section peuvent varier dans une très large mesure.The number of bosses 7, their arrangement and their sectional profile can vary to a very large extent.

On conçoit en particulier que compte tenu du gain de place obtenu diamétralement au niveau du moyeu de chaque organe oscillant 2, on peut interposer entre ledit moyeu et l'axe-support 1 un roulement à billes ou à aiguilles, propre à améliorer la rotation. Il va par ailleurs de soi que les bossages 7 de chaque pièce 5-6 sont susceptibles de ne s'étendre que sur une seule face de celle-ci, pour autant qu'il soient prévus suffisament longs pour venir porter contre la face lisse de la pièce adjacente.It is understood in particular that, given the space saving obtained diametrically at the hub of each oscillating member 2, it is possible to interpose between said hub and the support axis 1 a ball or needle bearing, capable of improving rotation. It also goes without saying that the bosses 7 of each part 5-6 are likely to extend only on one side thereof, provided that they are provided long enough to come to bear against the smooth face of the adjacent room.
