Description

La présente invention a trait aux ratières et autres mécaniques pour la formation de la foule sur les machines à tisser, et elle vise plus particulièrement l'accouplement des cadres de lisses sur les câbles ou autres éléments de transmission destinés à leur manoeuvre.The present invention relates to dobbies and other mechanical devices for training the crowd on weaving machines, and it relates more particularly to the coupling of heald frames on cables or other transmission elements intended for their operation.

On a proposé en pratique un grand nombre de systèmes différents, dont certains sont agencés pour permettre le réglage en hauteur des cadres de lisses, et on pourra se référer notamment aux documents FR-A-970 624 (TESSRAION), BE-A-521 289 (LINDAVER DORNIER), EP-A-325 547 (STAUBLI) et EP-A-161 375 (SULZER).A large number of different systems have been proposed in practice, some of which are arranged to allow height adjustment of the heald frames, and reference may be made in particular to documents FR-A-970 624 (TESSRAION), BE-A-521 289 (LINDAVER DORNIER), EP-A-325 547 (STAUBLI) and EP-A-161 375 (SULZER).

Dans le brevet FR-A-2 617 204 (STAUBLI) est décrit un dispositif d'accouplement comprenant des organes mâle et femelle conjugués en forme de tenons et de mortaises qui sont fixés les uns aux montants du cadre, les autres aux éléments de transmission. Les organes fixés aux montants sont fendus parallèlement au plan du cadre de façon à être traversés par les éléments de transmission et à ménager, de part et d'autre de ces derniers, des surfaces de contact entre les tenons et mortaises pour la transmission des efforts.In patent FR-A-2 617 204 (STAUBLI), a coupling device is described comprising male and female members combined in the form of tenons and mortises which are fixed to the uprights of the frame, the others to the transmission elements. . The members fixed to the uprights are split parallel to the plane of the frame so as to be traversed by the transmission elements and to provide, on either side of the latter, contact surfaces between the tenons and mortises for the transmission of forces .

Une telle disposition est très avantageuse du fait qu'elle permet de diminuer dans une mesure considérable, ou même d'éliminer pratiquement, le porte-à-faux existant entre chacun des montants du cadre de lisses et l'axe du câble qui assure le déplacement de celui-ci. En conséquence, les deux organes conjugués de chaque dispositif ne nécessitent aucune fixation réciproque, leur emboîtement à jeu réduit à la manière d'un tenon et d'une mortaise étant suffisant pour assurer à lui seul la transmission des efforts de tirage.Such an arrangement is very advantageous because it makes it possible to reduce to a considerable extent, or even to virtually eliminate, the overhang existing between each of the uprights of the heald frame and the axis of the cable which ensures the displacement of it. Consequently, the two conjugate members of each device do not require any reciprocal fixing, their interlocking with reduced clearance in the manner of a tenon and a mortise being sufficient to ensure the transmission of pulling forces on its own.

Dans la forme de réalisation envisagée et décrite dans le Brevet susmentionné, l'organe qui est destiné à être rendu solidaire de l'élément de transmission était doté d'un mécanisme comprenant un mors pourvu de deux facettes obliques opposées aptes à coopérer avec une rampe oblique ménagée sur l'un et l'autre de deux poussoirs assemblés l'un à l'autre par une vis de serrage. Si une telle structure permet bien le réglage précis du cadre de lisses par rapport à l'élément de transmission, il n'en reste pas moins que la construction est relativement complexe et coûteuse.In the embodiment envisaged and described in the aforementioned patent, the member which is intended to be made integral with the transmission element was provided with a mechanism comprising a jaw provided with two opposite oblique facets capable of cooperating with a ramp oblique formed on one and the other of two pushers assembled to each other by a clamping screw. If such a structure allows the precise adjustment of the heald frame relative to the transmission element, the fact remains that the construction is relatively complex and expensive.

Par ailleurs, en vue d'éviter tout déplacement latéral parasite de l'organe fixé sur l'élément de transmission au cours du fonctionnement du métier à tisser, notamment sous l'effet des efforts de torsion qui s'exercent sur les câbles qui constituent les éléments de transmission, il était nécessaire de faire comporter à l'organe considéré un talon dont l'extrémité libre est engagée à jeu réduit dans l'ouverture d'une coulisse verticale fixe. Il est clair que cette disposition complique malgré tout le montage des cadres de lisses.Furthermore, in order to avoid any parasitic lateral displacement of the member fixed to the transmission element during the operation of the loom, in particular under the effect of the torsional forces which are exerted on the cables which constitute the transmission elements, it was necessary to have the member considered a heel whose free end is engaged with reduced clearance in the opening of a fixed vertical slide. It is clear that this arrangement still complicates the assembly of heald frames.

C'est aux inconvénients sus-mentionnés que la présente invention entend principalement remédier, tout en conservant les avantages des dispositifs suivant le brevet FR-A-2 617 204 (STAUBLI).It is to the above-mentioned drawbacks that the present invention mainly intends to remedy, while retaining the advantages of the devices according to patent FR-A-2 617 204 (STAUBLI).

Le dispositif d'accouplement suivant la présente invention est défini à la revendication 1.The coupling device according to the present invention is defined in claim 1.

En fait l'invention consiste à réaliser l'organe qui est destiné à être fixé sur le câble ou autre élément de transmission sous la forme d'une douille cylindrique dont l'ouverture axiale est taraudée pour être montée par vissage sur une partie filetée prévue sur l'élément précité de façon à se trouver disposée au voisinage du sommet du cadre de lisses envisagé, laquelle douille présente au moins deux épaulements annulaires décalés axialement l'un au-dessus de l'autre en vue de coopérer avec les surfaces de contact conjuguées de l'organe rendu solidaire du montant du cadre de lisses.In fact, the invention consists in making the member which is intended to be fixed on the cable or other transmission element in the form of a cylindrical sleeve whose axial opening is tapped to be mounted by screwing on a threaded part provided on the aforementioned element so as to be arranged in the vicinity of the top of the envisaged heald frame, which sleeve has at least two annular shoulders offset axially one above the other in order to cooperate with the contact surfaces the combined body made integral with the amount of heald frame.

On conçoit que la fixation de la douille cylindrique par vissage permet un réglage au moins aussi précis et aisé que celui procuré par le mécanisme à mors et à poussoirs obliques du Brevet antérieur, tout en étant de structure très simplifiée, étant observé que ce réglage est susceptible d'être très aisément effectué par suite du positionnement de la douille dans la partie supérieure du cadre de lisses. Par ailleurs, le profil cylindrique de la douille autorise le libre déplacement angulaire de l'élément de transmission par rapport à l'environnement (cadres de lisses adjacents et/ou structure fixe) et à l'organe conjugué fixé au cadre, en évitant de la sorte de devoir assurer l'immobilisation angulaire de cette douille.It is understood that the fixing of the cylindrical sleeve by screwing allows adjustment at least as precise and easy as that provided by the jaws and oblique push mechanism of the prior patent, while being of very simplified structure, it being observed that this adjustment is likely to be very easily performed as a result of the positioning of the sleeve in the upper part of the heald frame. Furthermore, the cylindrical profile of the socket allows the angular free movement of the transmission element relative to the environment (adjacent heald frames and / or fixed structure) and to the conjugate member fixed to the frame, avoiding the kind of having to ensure the angular immobilization of this socket.

Le dessin annexé, donné à titre d'exemple, permettra de mieux comprendre l'invention :The attached drawing, given as an example, will allow a better understanding the invention:

Fig. 1 est une vue en perspective montrant, préalablement à leur montage, les pièces qui constituent le dispositif d'accouplement suivant l'invention.Fig. 1 is a perspective view showing, prior to their assembly, the parts which constitute the coupling device according to the invention.

Fig. 2 est une coupe verticale de ce même dispositif, une fois les pièces assemblées.Fig. 2 is a vertical section of this same device, once the parts have been assembled.

Fig. 3 est une coupe horizontale suivant le plan indiqué en III-III en fig. 2.Fig. 3 is a horizontal section along the plane indicated in III-III in fig. 2.

Sur ce dessin, la référence 1 désigne le montant supérieur d'un cadre de lisses CL, le bord vertical dudit montant qui est tourné vers l'extérieur étant découpé d'une rainure 10 à fond arrondi, en arrière de laquelle il est prévu trois trous traversants 11. La référence 2 désigne l'un des deux éléments de traction destinés à la manoeuvre verticale du cadre de lisses CL ; cet élément 2 est constitué par un câble qui est interrompu par une tige filetée 20 dont les extrémités sont pourvues d'embouts 21 aptes à être sertis ou autrement fixés sur les extrémités du câble.In this drawing, the reference 1 designates the upper upright of a heald frame CL, the vertical edge of said upright which faces outwards being cut out by a groove 10 with a rounded bottom, behind which there are three through holes 11. The reference 2 designates one of the two traction elements intended for the vertical operation of the heald frame CL; this element 2 consists of a cable which is interrupted by a threaded rod 20, the ends of which are provided with end pieces 21 suitable for being crimped or otherwise fixed to the ends of the cable.

Comme illustré en fig. 1 à 3, sur la tige 20 est engagée une douille 3 qui présente deux butées cylindriques superposées 30 à plus grand diamétre, dont chacune définit ainsi deux épaulements annulaires opposés 31 et 32 ; on observera qu'au niveau de la butée inférieure 30, l'ouverture axiale de la douille 3 est prévue filetée en 33 pour coopérer avec le filetage de la tige 20. On notera encore que la butée supérieure 30 est surmontée d'une partie 34 établie à un profil hexagonal, à laquelle est associé un contre-écrou 35 vissé sur la tige 20.As illustrated in fig. 1 to 3, on the rod 20 is engaged a sleeve 3 which has two superimposed cylindrical stops 30 with larger diameter, each of which thus defines two opposite annular shoulders 31 and 32; it will be observed that at the lower stop 30, the axial opening of the sleeve 3 is provided threaded at 33 to cooperate with the thread of the rod 20. It will also be noted that the upper stop 30 is surmounted by a part 34 established with a hexagonal profile, with which is associated a lock nut 35 screwed onto the rod 20.

A cette douille 3, assimilable à un organe en forme de tenon ainsi qu'on le comprendra mieux ci-après, est conjugué un organe 4 formant mortaise, lequel organe est porté par le montant supérieur 1. Comme montré, cet organe 4 est constitué par deux flasques verticaux 40 assemblés l'un à l'autre par des entretoises 41 et fixés au montant 1 à l'aide de boulons ou rivets 42 engagés à travers les trous 11 dudit montant et des trous correspondants 43 ménagés dans lesdits flasques. On observera que chaque flasque 40 est découpé de deux entailles 44 superposées, dont chacune définit deux bords horizontaux référencés 45 et 46.With this socket 3, comparable to a body in the shape of a tenon as will be better understood below, is combined a body 4 forming a mortise, which body is carried by the upper upright 1. As shown, this body 4 is constituted by two vertical flanges 40 assembled to one another by spacers 41 and fixed to the upright 1 by means of bolts or rivets 42 engaged through the holes 11 of said upright and corresponding holes 43 formed in said flanges. It will be observed that each flange 40 is cut out of two superimposed notches 44, each of which defines two horizontal edges referenced 45 and 46.

On conçoit que moyennant un dimensionnement convenable des entretoises 41, la douille ou tenon 3 est susceptible d'être engagée entre les flasques 40 de l'organe femelle ou mortaise 4, à la manière illustrée en fig. 2 et 3. Comme montré en fig. 2, les butées 30 s'introduisent dans les entailles 44, de sorte que les épaulements 31 et 32 viennent prendre appui contre les surfaces de contact constituées par les bords horizontaux 45 et 46 desdites entailles. La tige filetée 20 vient bien entendu se loger dans la rainure 10 du montant 1, de sorte qu'on obtient la suppression pratique de tout effet de porte-à-faux, de la même manière que dans le brevet français mentionné au début des présentes.It is understood that by means of a suitable dimensioning of the spacers 41, the sleeve or tenon 3 is capable of being engaged between the flanges 40 of the female or mortise member 4, in the manner illustrated in FIG. 2 and 3. As shown in fig. 2, the stops 30 are introduced into the notches 44, so that the shoulders 31 and 32 come to bear against the contact surfaces formed by the horizontal edges 45 and 46 of said notches. The threaded rod 20 is of course housed in the groove 10 of the upright 1, so that the practical elimination of any overhang effect is obtained, in the same way as in the French patent mentioned at the beginning of this document. .

Pour le réglage en hauteur du cadre CL par rapport au câble 2, il suffit à l'opérateur de manoeuvrer en rotation, dans un sens ou dans l'autre, la douille 3 en agissant sur la partie hexagonale 34, le contre-écrou 35 étant serré une fois que la position désirée a été atteinte. L'opération n'implique que l'usage de deux clefs classiques et l'on observera qu'elle est au surplus simplifiée par suite de l'accessibilité remarquable des pièces 34 et 35, lesquelles se trouvent placées dans la partie supérieure des cadres. Le filetage intérieur 33 de la douille 3 est parfaitement protégé et ne risque pas d'être endommagé ; il en va de même pour le filetage de la tige 20 qui ne peut venir au contact des deux flasques 40 par suite de la présence de la douille 3.For the height adjustment of the frame CL relative to the cable 2, the operator need only operate the rotation 3 in one direction or the other, the sleeve 3 by acting on the hexagonal part 34, the lock nut 35 being tightened once the desired position has been reached. The operation only involves the use of two conventional keys and it will be observed that it is moreover simplified as a result of the remarkable accessibility of the parts 34 and 35, which are placed in the upper part of the frames. The internal thread 33 of the socket 3 is perfectly protected and does not risk being damaged; the same applies to the thread of the rod 20 which cannot come into contact with the two flanges 40 as a result of the presence of the sleeve 3.

Comme dans le brevet français antérieur, l'accouplement du cadre de lisses CL sur le câble 2 ne nécessite aucun organe de fixation, la solidarisation résultant du simple emboîtement de la douille ou tenon 3 dans l'organe ou mortaise 4 par suite des portées parallèles ménagées sur les tenons et mortaises. Il va cependant de soi que pour éviter tout risque de désacouplement intempestif sous l'effet des vibrations, on conserve les guides-cadres classiques prévus latéralement sur la structure fixe du métier, en prenant soin que ces guides-cadres 5 (fig. 1) viennent coopérer avec une parties lisse 22 prévue à cet effet sur chacune des tiges 20.As in the previous French patent, the coupling of the heald frame CL on the cable 2 does not require any fixing member, the joining resulting from the simple fitting of the socket or tenon 3 in the body or mortise 4 as a result of parallel spans formed on the tenons and mortises. However, it goes without saying that to avoid any risk of untimely uncoupling under the effect of vibrations, the conventional frame guides provided laterally on the fixed structure of the loom are kept, taking care that these frame guides 5 (fig. 1) cooperate with a smooth part 22 provided for this purpose on each of the rods 20.

Il va de soi que le nombre des butées 30 (et par là le nombre des épaulements annulaires et des surfaces de contact) peut varier dans une large mesure. Pour certaines applications, on peut se contenter d'une seule butée 30 coopérant avec une entaille 44 unique.It goes without saying that the number of stops 30 (and thereby the number of annular shoulders and contact surfaces) can vary to a large extent. For some applications, we can be satisfied with a single stop 30 cooperating with a single notch 44.
