Description

La présente invention a trait aux ratières et autres mécaniques d'armure du type négatif pour la formation de la foule sur les machines à tisser, et elle concerne plus particulièrement les systèmes de tirage destinés à opérer la commande des cadres de lisses associés à de telles mécaniques.The present invention relates to dobbies and other mechanical armor of the negative type for the formation of the crowd on weaving machines, and it relates more particularly to pulling systems intended to operate the control of heald frames associated with such mechanical.

On sait que les mécaniques du type négatif n'assurent la commande positive des cadres de lisses que dans un seul sens de la course de ceux-ci, de telle sorte qu'il y a lieu de prévoir des moyens élastiques agencés de façon à opérer le rappel desdits cadres à l'autre extrémité de la course.It is known that the mechanics of the negative type ensure the positive control of the heald frames in only one direction of travel thereof, so that it is necessary to provide elastic means arranged so as to operate the recall of said frames at the other end of the race.

En fait et comme on l'a schématiquement représenté à la fig. 1 du dessin annexé aux présentes, les moyens élastiques associés à chaque cadre de lisses sont le plus souvent constitués par deux séries ou "registres" de ressorts parallèles 1; dans chaque registre, ces ressorts sont retenus entre un ratelier 2 fixé à la structure 3 de la machine à tisser et une agrafe 4 articulée en 5 sur un levier oscillant 6, lequel est porté par un axe horizontal ou pivot 7 solidaire de ladite structure 3. Sur chacun des deux leviers oscillants 6 associés à un même cadre de lisses 8 vient s'arrimer, à l'opposé du point d'attelage 5 de l'agrafe 4 par rapport à l'axe 7, un câble de manoeuvre 10 qui est fixé latéralement au cadre 8 à commander et dont l'extrémité libre, convenablement renvoyée, est accrochée à l'organe mobile correspondant de la mécanique d'armure.In fact and as schematically shown in FIG. 1 of the drawing appended hereto, the elastic means associated with each heald frame are most often constituted by two series or "registers" of parallel springs 1; in each register, these springs are retained between a rack 2 fixed to the structure 3 of the weaving machine and a clip 4 articulated at 5 on an oscillating lever 6, which is carried by a horizontal axis or pivot 7 integral with said structure 3 On each of the two oscillating levers 6 associated with the same heald frame 8 is stowed, opposite the coupling point 5 of the clip 4 relative to the axis 7, an operating cable 10 which is fixed laterally to the frame 8 to be controlled and whose free end, suitably returned, is hooked to the corresponding movable member of the armor mechanism.

On comprend qu'un tel système de tirage assure bien la commande du cadre de lisses 8 puisque le déplacement de l'organe mobile précité provoque l'abaissement dudit cadre jusqu'à sa position basse à l'encontre des ressorts 1 qui sont aptes à ramener l'ensemble à la position haute par action sur chaque levier 6 dès que l'organe de la mécanique revient à sa position initiale.It is understood that such a pulling system provides good control of the heald frame 8 since the displacement of the aforementioned movable member causes the lowering of said frame to its low position against the springs 1 which are capable of return the assembly to the high position by action on each lever 6 as soon as the mechanical member returns to its initial position.

Ce système classique donne entière satisfaction pour autant que les vitesses de fonctionnement restent relativement modérées. Par contre, son comportement devient plus difficilement acceptable dès qu'on parvient aux vitesses élevées qui sont maintenant exigées des machines à tisser. On comprend en effet que le point d'attelage 5 se déplace suivant un arc de cercle concentrique à l'axe 7, si bien qu'au cours du fonctionnement, l'agrafe 4 subit l'écart transversal de positionnement référencé d. Ce déplacement continuel en va-et-vient impartit des vibrations qui nuisent au fonctionnement de l'ensemble des deux séries ou "registres" de ressorts 1.This conventional system is entirely satisfactory provided that the operating speeds remain relatively moderate. On the other hand, its behavior becomes more difficult to accept as soon as one reaches the high speeds which are now required of weaving machines. It is in fact understood that the coupling point 5 moves in an arc of a circle concentric with the axis 7, so that during operation, the clip 4 undergoes the transverse positioning deviation referenced d . This continuous back and forth movement imparts harmful vibrations the operation of all two series or "registers" of springs 1.

C'est à cet inconvénient qu'entend principalement remédier la présente invention, laquelle a pour objet le système de tirage qui est défini à la revendication 1.It is this drawback that the present invention mainly intends to remedy, which relates to the drawing system which is defined in claim 1.

Afin de compléter l'exposé ci-dessus quant à l'état de la technique, on rappelera très succinctement ci-après le contenu des trois documents cités dans le Rapport de Recherche.

  • 1. Dans DE-A-3433287 (ELITEX) on trouve un système de tirage dans lequel chacun des câbles actionnés par chaque organe mobile de la ratière se prolonge, au-delà de son point de fixation sur un levier oscillant attelé par une biellette au cadre de lisses, pour s'arrimer à des moyens élastiques de rappel.
  • 2. E-A-671649 (SERRA XAUS) montre un système de tirage dans lequel le câble manoeuvré par chaque organe mobile de la mécanique est attaché à un levier oscillant qui est arrimé à la base d'un bras solidaire de la traverse inférieure du cadre de lisses. Un mécanisme compensateur qui incorpore des moyens élastiques de rappel relie le levier oscillant précité à un second ensemble levier oscillant/bras, associé de manière équivalente à l'extrémité opposée de la traverse inférieure sus-mentionnée.
  • 3. Dans FR-A-2477186 (STAUBLI) le système de tirage, qui fait uniquement appel à des bras et bielles rigides, incorpore une seule nappe ou registre de ressorts qui agit simultanément sur les deux leviers oscillants associés à chaque cadre de lisses.
In order to complete the above statement as to the state of the art, the content of the three documents cited in the Research Report will be very briefly recalled below.
  • 1. In DE-A-3433287 (ELITEX) there is a pulling system in which each of the cables actuated by each movable member of the dobby extends beyond its point of attachment to an oscillating lever coupled by a link to the heald frame, for securing to elastic return means.
  • 2. EA-671649 (SERRA XAUS) shows a pulling system in which the cable operated by each movable mechanical part is attached to an oscillating lever which is secured to the base of an arm secured to the lower crossmember of the frame. smooth. A compensating mechanism which incorporates elastic return means connects the above-mentioned oscillating lever to a second oscillating lever / arm assembly, associated in an equivalent manner with the opposite end of the aforementioned lower cross member.
  • 3. In FR-A-2477186 (STAUBLI) the pulling system, which uses only rigid arms and connecting rods, incorporates a single ply or register of springs which acts simultaneously on the two oscillating levers associated with each heald frame.

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:

  • Comme indiqué ci-dessus, fig. 1 montre schématiquement en élévation l'agencement d'un système de tirage classique.
  • Fig. 2 illustre de la même manière l'agencement d'un système établi conformément à l'invention.
  • Fig. 3 est une coupe verticale à plus grande échelle représentant le mode de fixation des deux câbles opposés sur l'un des leviers pivotants.
  • Fig. 4 illustre une autre forme de mise en oeuvre de l'invention.
  • Fg. 5 et 6 correspondent à deux variantes.
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:
  • As shown above, fig. 1 schematically shows in elevation the arrangement of a conventional drawing system.
  • Fig. 2 illustrates in the same way the arrangement of a system established in accordance with the invention.
  • Fig. 3 is a vertical section on a larger scale representing the method of fixing the two opposite cables on one of the pivoting levers.
  • Fig. 4 illustrates another form of implementation of the invention.
  • Fg. 5 and 6 correspond to two variants.

En fig. 2, on retrouve le câble principal 10, mais celui-ci vient se fixer sur un levier oscillant 11 de type particulier, qui est relié à l'agrafe 4 du registre correspondant de ressorts 1 par un organe flexible en forme de câble 12.In fig. 2, the main cable 10 is found, but the latter is fixed on an oscillating lever 11 of a particular type, which is connected to the clip 4 of the corresponding register of springs 1 by a flexible cable-shaped member 12.

Comme plus particulièrement montré en fig. 3, ce câble secondaire 12 s'enroule dans une gorge ou rainure 11a ménagée dans la périphérie du levier 11 concentriquement à l'axe de pivotement 7. L'une des extrémités de ce câble 12 est solidaire d'un étrier 13 (fig. 2) convenablement retenu sur l'agrafe 4, tandis que l'extrémité opposée comporte un embout 14 (fig. 3) logé dans la gorge 11a et pourvu d'une tige filetée qui vient se visser dans un taraudage radial d'un noyau cylindrique 15. Ce dernier reçoit de la même manière un embout identique 14 logé dans la gorge opposée 11b du levier 11 qui assure le guidage du câble principal 10, ce second embout 14 étant fixé à l'extrémité de celui-ci. Le noyau 15, convenablement épaulé latéralement, est ainsi susceptible de venir s'engager dans un berceau semi-cylindrique 11c pratiqué dans la périphérie du levier 11, entre les extrémités adjacentes des gorges 11a et 11b.As more particularly shown in fig. 3, the secondary cable 12 is wound in a groove or slot 11a formed in the periphery of the lever 11 concentrically to the pivot axis 7. One end of this cable 12 is secured to a bracket 13 (Fig 2) suitably retained on the clip 4, while the opposite end comprises an end piece 14 (fig. 3) housed in the groove 11 a and provided with a threaded rod which is screwed into a radial thread of a cylindrical core 15. The latter receives in the same way an identical end piece 14 housed in the opposite groove 11 b of the lever 11 which guides the main cable 10, this second end piece 14 being fixed at the end of it. The core 15, suitably supported laterally, is thus capable of coming to engage in a semi-cylindrical cradle 11 c formed in the periphery of the lever 11, between the adjacent ends of the grooves 11 a and 11 b .

On conçoit que par suite de la flexibilité des deux câbles secondaires 12 du système de tirage associé à chaque cadre de lisses 8, et de l'enroulement de ces câbles 12 dans une gorge 11a concentrique à l'axe de pivotement 7 des leviers 11, chaque agrafe 4 et les ressorts 1 qui lui sont accrochés sont animés d'un déplacement vertical alternatif parfaitement linéaire, sans aucune composante transversale susceptible d'engendrer des oscillations parasites, et ce quelle que soit la vitesse de ce déplacement alternatif.It is understood that as a result of the flexibility of the two secondary cables 12 of the pulling system associated with each heald frame 8, and the winding of these cables 12 in a groove 11 a concentric with the pivot axis 7 of the levers 11 , each clip 4 and the springs 1 which are attached to it are driven by a perfectly linear alternating vertical movement, without any transverse component capable of generating parasitic oscillations, regardless of the speed of this alternating movement.

Il convient d'observer que l'équilibre des efforts de traction qui s'exercent sur le noyau 15 permet la retenue en place de celui-ci dans son berceau 11c sans aucune nécessité d'un organe de fixation quelconque. La construction et le montage sont ainsi considérablement simplifiés.It should be observed that the balance of the tensile forces exerted on the core 15 allows the retention in place of the latter in its cradle 11 c without any need for any fixing member. Construction and assembly are thus considerably simplified.

L'élimination des oscillations parasites de l'ensemble du registre et des vibrations à grande vitesse est telle que ledit registre peut, sans inconvénient aucun, être disposé à l'horizontale, ce qui ne pouvait être envisagé jusqu'à ce jour du fait que l'effet de la pesanteur venait s'ajouter aux vibrations transversales sus-mentionnées. On peut voir (en fig. 4) que chacun des deux câbles principaux 10 attachés au même organe mobile de la mécanique 16 est renvoyé pour venir s'attacher à un noyau 15 qui reçoit, comme en fig. 2 et 3, l'extrémité d'un câble secondaire 12 arrimé sur l'agrafe 4 du registre de ressorts 1 considéré. Ce noyau 15 est retenu sur un levier oscillant 11, ici supposé sous la forme d'une poulie à profil substantiellement circulaire montée folle sur un axe 7 porté par la poutre horizontale 3a qui relie les structures verticales 3 de la machine à tisser.The elimination of parasitic oscillations from the entire register and of the vibrations at high speed is such that said register can, without any disadvantage, be arranged horizontally, which could not be envisaged until now because the effect of gravity was added to the above-mentioned transverse vibrations. We can see (in fig. 4) that each of the two main cables 10 attached to the same movable member of the mechanics 16 is returned to attach to a core 15 which receives, as in fig. 2 and 3, the end of a secondary cable 12 stowed on the clip 4 of the spring register 1 considered. This core 15 is retained on an oscillating lever 11, here assumed in the form of a pulley with a substantially circular profile mounted idly on an axis 7 carried by the horizontal beam 3 a which connects the vertical structures 3 of the weaving machine.

Le ratelier 2 est lui-même fixé verticalement sur cette poutre 3a et le mouvement parfaitement linéaire des ressorts permet de glisser entre ceux-ci des éléments intercalaires 17 qui peuvent être avantageusement réalisés sous la forme de plaques. Ces éléments 17 servent de guides et de stabilisateurs et ils évitent que les ressorts viennent s'entrechoquer, en contribuant de la sorte à prolonger leur durée de vie. Dans la construction envisagée, on a supposé que chaque levier ou poulie 11 était réuni au cadre de lisses 8 à commander par une bielle réglable 18 associée à un maneton 19 solidaire radialement dudit levier ou poulie 11.The rack 2 is itself fixed vertically on this beam 3 a and the perfectly linear movement of the springs makes it possible to slide between these intermediate elements 17 which can advantageously be produced in the form of plates. These elements 17 serve as guides and stabilizers and they prevent the springs from colliding, thereby helping to prolong their service life. In the envisaged construction, it has been assumed that each lever or pulley 11 is joined to the heddle frame 8 to be controlled by an adjustable rod 18 associated with a crank pin 19 radially integral with said lever or pulley 11.

L'orientation horizontale des registres de ressorts 1 autorise l'implantation desdits registres dans la partie, le plus souvent peu encombrée, de la machine à tisser qui surmonte les cadres de lisses 8. Cette orientation horizontale est obtenue grâce à l'adoption des câbles secondaires 12 et à leur enroulement sur une portée des leviers 11 concentrique à l'axe de rotation 7 de ceux-ci, et grâce au montage des intercalaires 17 entre les ressorts 1.The horizontal orientation of the spring registers 1 allows the implantation of said registers in the part, most often not crowded, of the weaving machine which surmounts the heald frames 8. This horizontal orientation is obtained thanks to the adoption of cables secondary 12 and their winding on a bearing of the levers 11 concentric with the axis of rotation 7 thereof, and thanks to the mounting of the spacers 17 between the springs 1.

En outre, cette même orientation horizontale permet d'assurer le rappel élastique de chaque cadre de lisses 8 à l'aide d'un registre de ressorts unique, tel que celui indiqué en 20 en fig. 5. Dans un tel registre 20, les ressorts 1, séparés par des éléments intercalaires non représentés, sont tendus entre deux agrafes 4 dont chacune forme point d'attache pour l'un ou l'autre des deux câbles secondaires 12. Dans la variante de fig. 6 où le cadre 8 présente une plus grande longueur, l'un des câbles 12 prévu plus long que l'autre, coopère avec une poulie intermédiaire de renvoi référencée 21.In addition, this same horizontal orientation makes it possible to ensure the elastic return of each heald frame 8 using a single spring register, such as that indicated in FIG. 5. In such a register 20, the springs 1, separated by not shown intermediate elements, are stretched between two clips 4 each of which forms an attachment point for one or the other of the two secondary cables 12. In the variant of fig. 6 where the frame 8 has a greater length, one of the cables 12 provided longer than the other, cooperates with an intermediate return pulley referenced 21.
