The effect of friction, and heating, are reduced. <IMAGE>

Description

La présente invention a trait aux mécaniques d'armure destinées à assurer la commande des cadres de lisses ou éléments similaires montés sur les métiers à tisser en vue de la formation de la foule, et elle vise plus particulièrement parmi ces mécaniques celles du type dit "rotatif".The present invention relates to the armor mechanics intended to ensure the control of heald frames or similar elements mounted on the weaving looms with a view to forming the crowd, and it relates more particularly among these mechanics those of the so-called " rotary".

On sait que dans ces mécaniques rotatives, le mouvement vertical alternatif des cadres de lisses est assuré par des pièces oscillantes qui peuvent suivant les cas être constituées soit par des ensembles bielle-levier, soit par des leviers porte-galets, ces pièces oscillantes étant commandées par des éléments d'actionnement (en forme d'excentriques dans le premier cas, de cames dans le second) 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 mécanique (c'est-à-dire de l'unité d'actionnement associée à chaque cadre de lisses) et en fonction du dessin ou armure à obtenir sur le tissu en cours de tissage, solidariser l'élément d'actionnement soit avec ledit arbre pour commander la pièce oscillante, soit avec un point fixe afin d'opérer l'immobilisation angulaire de cette dernière.We know that in these rotary mechanics, the alternating vertical movement of the heald frames is ensured by oscillating parts which can, depending on the case, be constituted either by rod-lever assemblies, or by roller-bearing levers, these oscillating parts being controlled by actuating elements (in the form of eccentrics in the first case, of cams in the second) mounted on the main shaft of the mechanics. 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 mechanics (that is to say the actuation unit associated with each heald frame) and depending on the pattern or weave to be obtained on the fabric being woven, secure the actuating element either with said shaft to control the oscillating part, either with a fixed point in order to operate the angular immobilization of the latter.

Cette solidarisation sélective est généralement obtenue à l'aide d'au moins un organe mobile d'accouplement en forme de clavette, de crochet ou de cliquet, soumis à l'action de deux leviers pivotants disposés de part et d'autre de l'arbre afin d'actionner ledit organe mobile aux deux positions d'arrêt de celui-ci, chaque paire de leviers pivotants étant placée sous la dépendance du dispositif de lisage de la mécanique.This selective joining is generally obtained using at least one movable coupling member in the form of a key, hook or ratchet, subjected to the action of two pivoting levers arranged on either side of the shaft in order to actuate said movable member at the two stop positions thereof, each pair of pivoting levers being placed under the dependence of the mechanical reading device.

Au cours des dernières années, les vitesses de fonctionnement des métiers à tisser et en conséquence celles des mécaniques d'armure qui leur sont associées sont allées en croissant dans une mesure considérable, au point qu'il est en pratique impossible d'envisager une commande précise à l'aide d'une impulsion fugitive appliquée lors des arrêts cycliques d'une pièce en mouvement. Aussi est-on contraint d'avoir recours à des moyens élastiques qui agissent en permanence sur les leviers pivotants précités dont les becs d'extrémité sont ainsi plaqués, bien avant l'arrêt de l'arbre, contre des rampes ou autres surfaces courbes similaires afin de s'engager automatiquement, dès l'arrêt, dans des entailles ou encoches pratiquées dans lesdites surfaces, le dispositif de lisage se contentant d'agir à l'encontre des moyens élastiques sus-mentionnés lorsque la commande ne doit pas avoir lieu. Les demandes de brevets français de la Demanderesse N° 81 20502 du 29 Octobre 1981 et 83 02271 du 7 Février 1983 illustrent particulièrement bien le propos qui précède.In recent years, the operating speeds of the weaving looms and, consequently, those of the associated armor mechanics have increased considerably, to the point that it is in practice impossible to envisage an order. precise using a fleeting pulse applied during cyclic stops of a moving part. So we are forced to use elastic means which act permanently on the aforementioned pivoting levers whose end spouts are thus pressed, well before stopping the shaft, against ramps or other similar curved surfaces in order to automatically engage, upon stopping, in notches or notches made in said surfaces, the reading device is content to act against the above-mentioned elastic means when the order must not take place. The French patent applications of the Applicant N ° 81 20502 of October 29, 1981 and 83 02271 of February 7, 1983 illustrate the above statement particularly well.

Or, l'expérience a démontré que les frottements quasi-permanents ainsi créés impliquaient une dépense d'énergie très importante qui obligeait à faire appel à des moteurs d'entraînement plus puissants, en même temps qu'ils engendraient une usure prématurée des pièces, nécessitant alors le recours à des traitements de surface très coûteux.However, experience has shown that the quasi-permanent friction thus created involved a very significant energy expenditure which required the use of more powerful drive motors, at the same time as they caused premature wear of the parts, thus requiring the use of very expensive surface treatments.

C'est à ces inconvénients qu'entend remédier la présente invention, laquelle consiste essentiellement à faire comporter à l'extrémité des leviers pivotants de commande de la mécanique d'armure, au moins un galet tournant propre à rouler contre le bord périphérique des disques, plateaux ou autres surfaces mobiles de la mécanique, ledit galet étant propre à coopérer avec des entailles ou encoches convenablement profilées ménagées dans ces surfaces.It is to these drawbacks that the present invention intends to remedy, which essentially consists in having at the end of the pivoting levers for controlling the armor mechanics, at least one rotating roller capable of rolling against the peripheral edge of the discs. , plates or other movable surfaces of the mechanics, said roller being able to cooperate with notches or suitably profiled notches formed in these surfaces.

  • The single figure is a schematic cross section of a mechanism comprising application of the improvements according to the invention, this section showing the arrangement of one of the blades thereof.

En fait, le dessin représente une mécanique pratiquement identique dans son agencement général à celui de la ratière qui fait l'objet de la demande de brevet français N° 83 02271 déposée le 7 Février 1983 au nom de la Demanderesse.In fact, the drawing represents a mechanics practically identical in its general arrangement to that of the dobby which is the subject of French patent application No. 83 02271 filed on February 7, 1983 in the name of the Applicant.

La référence 1 désigne en conséquence l'arbre principal de la ratière, animé d'un mouvement de rotation intermittent avec arrêt tous les 180°. Cet arbre 1 reçoit une série de roulements en nombre égal à celui des cadres de lisses du métier, et sur chaque roulement est monté fou un excentrique 2 solidaire latéralement d'un plateau 3 ; sur chaque excentrique 2 tourillonne l'ouverture d'une bielle 4 dont l'extrémité libre s'attelle à un bras pivotant 5 qui assure, grâce à un câble 6a, le déplacement vertical du cadre de lisses 6 de la lame envisagée. Entre deux excentriques 2 contigus l'arbre 1, prévu crénelé, porte un disque d'entraînement 7 qui lui est solidaire et dont la périphérie est découpée de deux encoches radiales 7a, diamétralement opposées l'une à l'autre. Ces encoches 7a sont destinées à recevoir sélectivement le doigt terminal 8a d'un crochet ou cliquet 8 articulé sur un axe 9 porté par le plateau latéral 3 de l'excentrique 2 correspondant ; un ressort 10 tend à rappeler en permanence le doigt 8a du cliquet 8 en direction de l'arbre 1.The reference 1 consequently designates the main shaft of the dobby, animated by an intermittent rotational movement with stopping every 180 °. This shaft 1 receives a series of bearings in number equal to that of the heald frames of the loom, and on each bearing is mounted an eccentric 2 attached laterally to a plate 3; on each eccentric 2 pivots the opening of a connecting rod 4 whose free end is coupled to a pivoting arm 5 which ensures, thanks to a cable 6a, the vertical displacement of the heald frame 6 of the envisaged blade. Between two contiguous eccentrics 2 the shaft 1, crenellated, carries a drive disc 7 which is integral with it and the periphery of which is cut out by two radial notches 7a, diametrically opposite one another. These notches 7a are intended to selectively receive the terminal finger 8a of a hook or pawl 8 articulated on an axis 9 carried by the lateral plate 3 of the corresponding eccentric 2; a spring 10 tends to permanently recall the finger 8a of the pawl 8 in the direction of the shaft 1.

La commande de chaque cliquet 8 est assurée à l'aide de deux leviers pivotants 11 portés à articulation par des axes fixes 12 orientés parallèlement à l'arbre 1. Chaque levier 11 présente un profil en équerre et est sollicité par un ressort 13 afin de venir en appui contre une butée fixe correspondante 14. Ces deux butées 14 définissent ainsi sur chaque levier 11 une queue d'actionnement lla, susceptible d'être commandée par des poussoirs (flèches 15) du dispositif de lisage de la ratière.The control of each pawl 8 is ensured by means of two pivoting levers 11 carried at articulation by fixed axes 12 oriented parallel to the shaft 1. Each lever 11 has a square profile and is biased by a spring 13 in order to come to bear against a corresponding fixed stop 14. These two stops 14 thus define on each lever 11 an actuating tail lla, capable of being controlled by pushers (arrows 15) of the reading device of the dobby.

L'extrémité opposée llb de chaque levier 11 est destinée à coopérer avec l'une de deux rampes ou oreilles 3a, 3b prévues en deux points diamétralement opposés du plateau 3. Chacune de ces oreilles est creusée d'une entaille 3c, respectivement 3d, le cliquet basculant 8 porté par le plateau 3 étant pourvu, en vis-à-vis de l'entaille 3c, d'un talon terminal 8b destiné à son actionnement par l'extrémité de l'un des leviers 11 lorsque l'extrémité llb de celui-ci coopère avec l'entaille 3c sus-mentionnée.The opposite end llb of each lever 11 is intended to cooperate with one of two ramps or ears 3a, 3b provided at two diametrically opposite points of the plate 3. Each of these ears is hollowed out by a notch 3c, respectively 3d, the tilting pawl 8 carried by the plate 3 being provided, facing the notch 3c, with a terminal heel 8b intended for its actuation by the end of one of the levers 11 when the end llb of the latter cooperates with the 'notch 3c mentioned above.

L'agencement et le fonctionnement de la ratière ci-dessus décrite sont identiques à ceux exposés dans la demande de brevet français N° 83 02271, de telle sorte qu'il est inutile de s'y attarder : l'actionnement des leviers 11 par les poussoirs 15 du dispositif de lisage assure par l'intermédiaire des extrémités llb la commande des cliquets 8 au désaccouplement et l'immobilisation angulaire des plateaux 3 correspondants.The layout and operation of the dobby described above are identical to those set out in French patent application No. 83 02271, so that there is no need to dwell on it: the actuation of the levers 11 by the pushers 15 of the reading device ensures via the ends llb the control of the pawls 8 to uncoupling and the angular immobilization of the corresponding plates 3.

Il convient cependant d'observer qu'alors que dans la demande antérieure l'extrémité llb de chaque levier pivotant 11 est formée par un simple bec qui sous l'action du ressort 13 vient porter élastiquement contre la périphérie des oreilles 3a et 3b pour s'engager automatiquement dans l'une ou l'autre des entailles 3c ou 3d lors de l'arrêt de l'arbre 1 et du plateau 3, dans le présent cas cette extrémité llb porte un petit galet fou, référencé 16, qui sur le plan fonctionnel joue identiquement le même rôle que le bec qu'il remplace.It should however be observed that while in the previous application the end llb of each pivoting lever 11 is formed by a simple spout which under the action of the spring 13 comes to bear elastically against the periphery of the ears 3a and 3b for s '' automatically engage in one or other of the notches 3c or 3d when stopping the shaft 1 and the plate 3, in this case this end llb carries a small crazy roller, referenced 16, which on the functionally plays the same role as the spout it replaces.

On conçoit qu'au cours du fonctionnement de la mécanique, chaque galet 16 vient au contact de la périphérie des oreilles 3a et 3b contre laquelle il roule. L'effet de friction est parfaitement constant et il est plus faible que dans le cas du frottement aléatoire d'un bec fixe, de telle sorte que l'énergie consommée est bien inférieure et qu'il n'y a en fait aucun dégagement sensible de chaleur. L'on peut dans ces conditions se dispenser de tout traitement de surface au niveau des oreilles 3a et 3b.It is understood that during the operation of the mechanics, each roller 16 comes into contact with the periphery of the ears 3a and 3b against which it rolls. The friction effect is perfectly constant and it is weaker than in the case of the random friction of a fixed spout, so that the energy consumed is much lower and that there is in fact no appreciable release heat. Under these conditions, it is possible to dispense with any surface treatment at the ears 3a and 3b.

Il va de soi que les entailles 3c et 3d doivent présenter un profil approprié pour coopérer avec les galets 16, en fonction du rôle qui est assigné auxdites entailles. L'entaille 3c, destinée à assurer en liaison avec l'un des leviers 11 le blocage positif du plateau 3 à l'encontre de toute rotation, présente un angle d'ouverture réduit et une profondeur adéquate afin d'éviter tout retrait intempestif du galet 16 une fois celui-ci introduit dans ladite entaille. En revanche l'entaille 3d, propre à opérer, lors de l'arrêt de l'arbre 1, le simple positionnement du plateau 3 dans le cas du fonctionnement en marche arrière, est établie à un angle d'ouverture plus large et à une profondeur bien inférieure, afin que le positionnement obtenu cesse de lui-même moyennant éjection du galet 16 lorsque l'arbre 1 et le plateau 3 sont à nouveau entraînés en rotation.It goes without saying that the notches 3c and 3d must have an appropriate profile for cooperating with the rollers 16, depending on the role which is assigned to said notches. The notch 3c, intended to ensure in connection with one of the levers 11 the positive blocking of the plate 3 against any rotation, has a reduced opening angle and an adequate depth in order to avoid any untimely withdrawal of the roller 16 once it has been introduced into said notch. On the other hand, the notch 3d, suitable for operating, when the shaft 1 stops, the simple positioning of the plate 3 in the case of reverse operation, is established at a wider opening angle and at a much lower depth, so that the positioning obtained ceases on its own by ejecting the roller 16 when the shaft 1 and the plate 3 are again driven in rotation.

On observera que le couple d'éjection est ici limité à une valeur minimale, alors que dans la pratique antérieure il était soumis à des variations liées aux forces de frottement découlant des états de surface, des lubrifiants employés, des températures, etc...It will be observed that the ejection torque is here limited to a minimum value, whereas in prior practice it was subjected to variations linked to the frictional forces arising from the surface conditions, the lubricants used, the temperatures, etc.

On conçoit par ailleurs que l'invention n'est pas limitée au type de mécanique ci-dessus exposé et correspondant aux demandes de brevets français N° 81 20502 et 83 02271 ; bien au contraire elle est applicable à toutes les mécaniques pour la formation de la foule du type rotatif dans lesquelles les organes mobiles (clavettes, crochets ou cliquets) destinés accoupler l'arbre à rotation intermittente avec les pièces oscillantes (ensembles bielles-leviers ou leviers porte-galets) associées aux cadres de lisses sont actionnés à l'aide de leviers pivotants que des moyens élastiques tendent à appliquer, au moins de manière cyclique, contre la périphérie entaillée d'éléments tournants.It is also understood that the invention is not limited to the type of mechanics described above and corresponding to French patent applications No. 81 20502 and 83 02271; on the contrary, it is applicable to all mechanics for the formation of the rotary type crowd in which the movable members (keys, hooks or pawls) intended to couple the shaft with intermittent rotation with the oscillating parts (rod-lever assemblies or levers roller carriers) associated with the heald frames are actuated using pivoting levers which elastic means tend to apply, at least cyclically, against the notched periphery of rotating elements.
