Description

L'invention a trait à un dispositif pour l'accouplement d'un cadre de lisses sur un élément de transmission de mouvement d'une mécanique d'armure. L'invention a également trait à un ensemble d'entraînement des cadres de lisses à un métier à tisser incorporant un tel dispositif et à un métier à tisser équipé d'un tel dispositif ou d'un tel ensemble.The invention relates to a device for coupling a heald frame to a motion transmission element of a weave mechanism. The invention also relates to a training set of heald frames to a loom incorporating such a device and to a loom equipped with such a device or such an assembly.

Il est connu de prévoir des systèmes mécaniques pour solidariser les cadres d'un métier à tisser avec des tiges ou câbles entraînés avec un mouvement vertical oscillant par une mécanique d'armure, notamment une ratière. EP-A-0 297 003 et EP-A-0 467 808 prévoient d'utiliser des éléments format respectivement tenon et mortaise, ce qui permet un accrochage efficace et rapide du cadre sur l'élément de transmission. Cependant, ces dispositifs connus présentent certaines limitations.It is known to provide mechanical systems for securing the frames of a loom with rods or cables driven with a vertical movement oscillating by a mechanism of armor, including a dobby. EP-A-0 297 003 and EP-A-0 467 808 plan to use format elements respectively tenon and mortise, which allows a quick and effective attachment of the frame on the transmission element. However, these known devices have certain limitations.

Le dispositif de EP-A-0 297 003 prévoit un réglage longitudinal du tenon sur une tige de transmission de mouvement par adhérence et coincement, grâce à des éléments en forme de coin. En cas de mauvais serrage de ces éléments, un risque de glissement important existe, ce qui peut conduire à des avaries graves du métier à tisser, notamment par le blocage des cadres et/ou la rupture des tiges de liaison.The device EP-A-0 297 003 provides a longitudinal adjustment of the tenon on a movement rod by adhesion and jamming, thanks to wedge-shaped elements. In case of poor tightening of these elements, a significant risk of slipping exists, which can lead to serious damage to the loom, in particular by blocking the frames and / or breakage of the connecting rods.

Le dispositif de EP-A-0 467 808 prévoit que le réglage en hauteur est de type micrométrique grâce à un tenon comprenant un orifice central taraudé, ce qui évite des risques de glissement intempestif. Cependant, ce dispositif est tel que les surfaces en contact du tenon et de la mortaise sont relativement petites, alors que des efforts intenses sont transmis grâce à ces surfaces, avec des accélérations importantes, d'où un risque d'usure prématurée de ces surfaces par matage.The device EP-A-0 467 808 provides that the height adjustment is micrometric type thanks to a pin comprising a tapped central orifice, which avoids the risk of accidental slippage. However, this device is such that the contact surfaces of the tenon and the mortise are relatively small, while intense forces are transmitted through these surfaces, with significant accelerations, resulting in a risk of premature wear of these surfaces by matting.

C'est à ces inconvénients qu'entend plus particulièrement remédier l'invention en proposant un nouveau dispositif d'accouplement dans lequel un organe formant tenon est sécurisé par rapport à un élément de transmission de mouvement, alors que les surfaces en contact de cet élément formant tenon et de l'élément formant mortaise associé sont suffisamment importantes pour supporter des efforts intenses.It is these disadvantages that the invention more particularly intends to remedy by proposing a new coupling device in which a stud member is secured relative to a motion transmitting member, while the contacting surfaces of said pin member and the associated mortise member are sufficiently large to withstand intense forces.

Dans cet esprit, l'invention concerne un dispositif pour l'accouplement d'un cadre de lisses sur un élément de transmission de mouvement d'une mécanique d'armure, ce dispositif comprenant un organe mâle formant tenon monté sur l'élément de transmission et un organe femelle formant mortaise fixé sur un montant du cadre, l'organe-mortaise étant pourvu d'une fente centrale de passage de l'élément de transmission et définissant, de part et d'autre de cette fente, des surfaces de contact destinées à coopérer avec l'organe-tenon pour la transmission des efforts, caractérisé en ce que l'organe-tenon est formé par un ensemble comprenant :

  • un écrou vissé sur une partie filetée dudit élément de transmission ;
  • une noix d'accrochage formant au moins deux surfaces destinées à coopérer avec les surfaces de contact de l'organe-mortaise, cette noix étant pourvue d'un perçage traversant de passage de l'élément de transmission et de réception, avec possibilité de rotation, de l'écrou ;
  • une douille pourvue d'un perçage central de passage de l'élément de transmission et apte à entraîner l'écrou en rotation autour de l'élément de transmission, à travers le perçage de la noix et
  • un contre-écrou de serrage de la douille contre la noix et l'écrou précités.
In this spirit, the invention relates to a device for coupling a heald frame to a motion transmission element of a weave mechanism, this device comprising a male member forming a stud mounted on the transmission element. and a female mortise member fixed to a frame post, the mortise member being provided with a central slot for passage of the transmission element and defining, on either side of this slot, contact surfaces. intended to cooperate with the stud member for the transmission of forces, characterized in that the stud member is formed by an assembly comprising:
  • a nut screwed onto a threaded portion of said transmission member;
  • a hooking nut forming at least two surfaces intended to cooperate with the contact surfaces of the mortise-member, this nut being provided with a through bore for passage of the transmission and reception element, with the possibility of rotation , the nut;
  • a bushing provided with a central bore for passage of the transmission element and adapted to drive the nut in rotation around the transmission element, through the drilling of the nut and
  • a counter-nut for clamping the sleeve against the nut and the aforesaid nut.

Grâce à l'invention, les dimensions de la noix peuvent être prévues de telle sorte que ses surfaces destinées à coopérer avec l'organe-mortaise sont relativement importantes, alors que le réglage de la position longitudinale de l'organe-tenon n'impose pas de faire subir un mouvement de rotation à la noix autour de la tige filetée constituant l'élément de transmission, ce qui ne serait pas compatible avec la densité d'implantation habituelle des cadres dans un métier à tisser. En d'autres termes, l'écrou et le manchon permettent d'obtenir le réglage de la position de la noix le long de l'élément de transmission sans induire de rotation de cette noix, la noix pouvant ainsi conserver une orientation adaptée par rapport à l'élément-mortaise porté par le cadre.Thanks to the invention, the dimensions of the nut can be provided so that its surfaces intended to cooperate with the mortise-member are relatively important, while the adjustment of the longitudinal position of the member-pin imposes not to rotate the nut around the threaded rod constituting the transmission element, which would not be compatible with the usual implantation density of frames in a loom. In other words, the nut and the sleeve make it possible to obtain the adjustment of the position of the nut along the element of transmission without inducing rotation of this nut, the nut can thus maintain a suitable orientation relative to the mortise-element carried by the frame.

Selon des aspects avantageux de l'invention, le dispositif incorpore une ou plusieurs des caractéristiques suivantes :

  • L'écrou et la douille sont pourvus de reliefs de formes correspondantes permettant un crabotage de l'écrou et de la douille.
  • La douille est pourvue d'une tête à section polygonale, ce qui lui permet d'être entraînée en rotation au moyen d'une clé usuelle.
  • Le perçage de la noix comprend deux épaulements internes tournés respectivement vers les deux débouchés de ce perçage et destinés à coopérer respectivement avec des surfaces correspondantes de l'écrou et de la douille. Ces deux épaulements internes permettent de commander la position de la noix le long de l'élément de transmission grâce à l'écrou et à la douille.
  • La noix est pourvue d'au moins une protubérance apte à être engagée dans la fente de l'organe-mortaise. Cette protubérance assure un positionnement adapté de la noix par rapport à l'organe-mortaise et à l'environnement du cadre.
  • La noix est pourvue d'une extension dirigée à l'opposé de l'organe-mortaise lorsque l'organe-tenon est en place dans l'organe-mortaise, cette extension étant apte à être engagée dans une glissière de guidage et de retenue de l'organe-tenon. Dans ce cas, cette extension a avantageusement une section transversale globalement en forme de T.
According to advantageous aspects of the invention, the device incorporates one or more of the following features:
  • The nut and the bush are provided with correspondingly shaped reliefs for interconnecting the nut and the bushing.
  • The bushing is provided with a polygonal section head, which allows it to be rotated by means of a conventional key.
  • The drilling of the nut comprises two internal shoulders respectively turned towards the two outlets of this bore and intended to cooperate respectively with corresponding surfaces of the nut and the sleeve. These two internal shoulders make it possible to control the position of the nut along the transmission element by means of the nut and the socket.
  • The nut is provided with at least one protuberance adapted to be engaged in the slot of the mortise member. This protrusion ensures proper positioning of the nut with respect to the mortise member and the environment of the frame.
  • The nut is provided with an extension directed away from the mortise member when the member-pin is in place in the mortise member, this extension being adapted to be engaged in a guide and retaining slideway of the body-tenon. In this case, this extension advantageously has a generally T-shaped cross section.

L'invention concerne également un ensemble d'entraînement des cadres de lisses d'un métier à tisser qui comprend au moins un dispositif tel que précédemment décrit et un jeu de guides aptes à recevoir chacun une extension de la noix d'un tel dispositif, chaque guide ayant, en coupe transversale, une forme telle qu'il s'oppose à une extraction de l'extension selon une direction globalement perpendiculaire à la direction de coulissement de l'extension dans le guide considéré. On peut en outre prévoir que le guide est mobile selon une direction globalement perpendiculaire à la direction de coulissement, ce qui permet de commander un mouvement d'introduction/extraction de l'organe-tenon par rapport à l'organe-mortaise.The invention also relates to a drive assembly of the heald frames of a loom which comprises at least one device as previously described and a set of guides each capable of receiving an extension of the nut of such a device, each guide having, in cross-section, a shape such that it opposes extraction of the extension in a direction generally perpendicular to the direction of sliding of the extension in the considered guide. It can further be provided that the guide is movable according to a direction generally perpendicular to the direction of sliding, which allows to control a movement of introduction / extraction of the member-pin relative to the mortise-member.

L'invention concerne enfin un métier à tisser équipé d'un dispositif ou d'un ensemble tels que précédemment décrits. Un tel métier est plus facile à utiliser notamment lors des changements de cadres auxquels il doit être régulièrement procédé au cours de l'utilisation d'un tel métier.The invention finally relates to a loom equipped with a device or an assembly as previously described. Such a job is easier to use, especially during changes of frames which must be regularly performed during the use of such a craft.

L'invention sera mieux comprise et d'autres avantages de celle-ci apparaîtront plus clairement à la lumière de la description qui va suivre d'un mode de réalisation d'un dispositif et d'un ensemble conformes à son principe mis en oeuvre dans un métier également conforme à l'invention, donnée uniquement à titre d'exemple et faite en référence aux dessins annexés dans lesquels :

Le montant 12 est également pourvu de trois orifices traversants 14 permettant le montage d'une attache 20 formant mortaise et qui est constituée de deux flasques verticales 21 et 22 entre lesquelles est disposée une entretoise 23. Les flasques 21 et 22 sont pourvues de trois orifices 24 prévus pour être alignés avec les orifices 14 lors du montage de l'attache 20 sur le cadre 1.

Un ensemble 40 formant tenon est prévu pour être monté sur la tige 9 et introduit partiellement dans les entailles 261 et 262 pour interagir avec les bords 27 et 28.A tenon assembly 40 is provided to be mounted on the rod 9 and partially introduced into the notches 26 1 and 26 2 to interact with the edges 27 and 28.

Cet ensemble 40 comprend un écrou 41 destiné à être vissé sur une partie filetée 9a de la tige 9. Cet écrou 41 a une surface radiale externe 42 globalement cylindrique et présente deux dents 43 et 44 s'étendant chacune selon une direction globalement parallèle à un axe central X1 de la tige 9 lorsque l'écrou 41 est en place sur cette tige.This assembly 40 includes a nut 41 to be screwed on a threaded portion 9a of the shaft 9. The nut 41 has an outer radial surface 42 generally cylindrical and has two teeth 43 and 44 each extending in a direction generally parallel to a central axis X 1 of the rod 9 when the nut 41 is in place on this rod.

L'ensemble 40 comprend également une noix 45 pourvue d'un perçage traversant 46, qui n'est pas taraudé et dont les dimensions sont telles que la noix 45 peut librement coulisser autour de la partie filetée 9a.The assembly 40 also comprises a nut 45 provided with a through bore 46, which is not tapped and whose dimensions are such that the block 45 can slide freely around the threaded part 9 a.

Comme il ressort plus clairement de la figure 3, la surface radiale interne du perçage 46 est pourvue d'une collerette 47 définissant deux épaulements 48, 49 respectivement orientés vers le débouché inférieur 46a et vers le débouché supérieur 46b du perçage 46. Lorsque la noix 45 repose sur l'écrou 41, l'épaulement 48 est en appui sur la surface supérieure 41a de l'écrou 41.As is clear from the figure 3 , The radially inner surface of the bore 46 is provided with a flange 47 defining two shoulders 48, 49 respectively directed towards the lower opening 46a and to the upper opening 46 b of the bore 46. When the block 45 rests on the nut 41 , the shoulder 48 rests on the upper surface 41a of the nut 41.

La noix 45 est pourvue d'une protubérance 50 dont la largeur L50 est légèrement inférieure à la largeur l29 de la fente 29, de telle sorte que cette protubérance 50 peut être engagée dans la fente 29 de l'attache 20. La protubérance 50 est interrompue par le perçage 46.The nut 45 is provided with a protuberance 50 whose width L 50 is slightly smaller than the width l 29 of the slot 29, so that this protuberance 50 can be engaged in the slot 29 of the fastener 20. The protuberance 50 is interrupted by drilling 46.

De part et d'autre de la protubérance 50 sont définies deux surfaces 51 et 52 destinées à venir en appui contre les bords supérieurs 28 des entailles 261 et 262. La longueur L des surfaces 51 et 52 est relativement importante ce qui permet un appui réparti de la noix 45 sur les bords 28.On either side of the protuberance 50 are defined two surfaces 51 and 52 intended to bear against the upper edges 28 of the notches 26 1 and 26 2 . The length L of the surfaces 51 and 52 is relatively large which allows a distributed support of the nut 45 on the edges 28.

La surface inférieure 53 de la noix 45, c'est-à-dire la surface opposée aux surfaces 51 et 52, constitue une surface d'appui sur les bords 27 des entailles 261 et 262.The lower surface 53 of the nut 45, that is to say the surface opposite the surfaces 51 and 52, constitutes a bearing surface on the edges 27 of the notches 26 1 and 26 2 .

Selon un mode de réalisation non représenté de l'invention, il serait possible de prévoir une protubérance analogue à la protubérance 50 au niveau de la surface 53.According to a not shown embodiment of the invention, it would be possible to provide a protuberance similar to the protuberance 50 at the surface 53.

La noix 45 est également pourvue d'une extension 54 à section transversale globalement en forme de T qui est destinée à être engagée dans un guide en forme de glissière 100 définissant une rainure 101 à section interne globalement en forme de T. La largeur minimum l101 de la rainure 101 est inférieure à la largeur maximum l54 de l'extension 54, de telle sorte qu'une fois engagée dans la rainure 101, l'extension 54 ne peut pas en être déplacée dans le plan du cadre selon une direction Y-Y' perpendiculaire à sa direction X2 de coulissement dans le guide 100.The nut 45 is also provided with a generally T-shaped cross-section extension 54 which is intended to be engaged in a slide-shaped guide 100 defining a groove 101 with a generally T-shaped inner section. The minimum width l 101 of the groove 101 is smaller than the maximum width 54 of the extension 54, so that once engaged in the groove 101, the extension 54 can not be moved in the plane of the frame in one direction YY 'perpendicular to its direction X 2 sliding in the guide 100.

Une douille 55 appartient également à l'ensemble 40 et est pourvue d'un perçage central 56 de diamètre suffisant pour permettre un coulissement de la douille 55 autour de la partie 9a de la tige 9. La douille 55 est pourvue d'une collerette radiale externe 57 destinée à venir en appui contre l'épaulement 49 lorsque la partie inférieure 58 de la collerette 57 est engagée dans le perçage 46. La partie 58 est pourvue de dents 59 et 60 aptes à venir en prise avec les dents 43 et 44 de l'écrou 41, à travers le perçage 46, ce qui permet de solidariser en rotation les éléments 41 et 55.A bushing 55 also belongs to the assembly 40 and is provided with a central bore 56 of sufficient diameter to allow sliding of the sleeve 55 around the part 9a of the rod 9. The bush 55 is provided with an external radial flange 57 intended to come into abutment against the shoulder 49 when the lower portion 58 of the collar 57 is engaged in the bore 46. The portion 58 is provided teeth 59 and 60 adapted to engage the teeth 43 and 44 of the nut 41, through the bore 46, which allows the elements 41 and 55 to be joined in rotation.

La douille 55 est également pourvue d'une tête hexagonale 61 permettant sa manoeuvre grâce à une clé classique.The bushing 55 is also provided with a hexagonal head 61 allowing its operation by means of a conventional key.

Un contre-écrou 62 est également prévu dans l'ensemble 40 pour être vissé sur la partie 9a de la tige 9 afin de bloquer la douille 55 contre la noix 45 et l'écrou 41. L'organe tenon 40 comprend donc un ensemble formé des éléments 41, 45, 55 et 62.Against a nut 62 is also provided in the assembly 40 to be screwed onto the portion 9a of the stem 9 in order to block the sleeve 55 against the block 45 and the nut 41. The stud member 40 therefore comprises a set formed elements 41, 45, 55 and 62.

Grâce aux dimensions des surfaces 51, 52 et 53, l'appui de l'organe-tenon 40 contre l'organe-mortaise 20 est réparti sur des aires relativement importantes, ce qui évite un matage des surface 51 à 53 ou des bords 27 et 28.Thanks to the dimensions of the surfaces 51, 52 and 53, the support of the tenon member 40 against the mortise member 20 is distributed over relatively large areas, which avoids a matting of the surfaces 51 to 53 or edges 27 and 28.

Le réglage de la position de l'ensemble 40 le long de la tige 9 est micrométrique et réalisé grâce à l'écrou 41 sur lequel repose la douille 45. En effet, lorsqu'il convient d'ajuster la position de l'ensemble 40, il suffit de manoeuvrer la douille 55 à la main pour entraîner en rotation l'écrou 41 qui tourne alors librement à l'intérieur du perçage 46 et se déplace le long de la tige 9 en entraînant en translation la noix 45 sans entraîner celle-ci en rotation. Lorsque la position recherchée est atteinte, il suffit de serrer le contre-écrou 62 contre la douille 55 en utilisant la tête hexagonale 61, ce qui a pour effet d'immobiliser fermement l'ensemble 40, et en particulier la noix 45, sur la tige 9. Le réglage de la position longitudinale de l'ensemble 40 par rapport à la tige 9 a lieu sans que la noix 45 ne soit mise en rotation, ce qui permet de conserver l'extension 54 en place dans le guide 100 et évite une interférence entre des organes-tenons adjacents dans un métier à tisser.The adjustment of the position of the assembly 40 along the rod 9 is micrometric and achieved by means of the nut 41 on which the sleeve 45 rests. Indeed, when it is necessary to adjust the position of the assembly 40 it is sufficient to maneuver the bushing 55 by hand in order to rotate the nut 41 which then rotates freely inside the bore 46 and moves along the rod 9 by driving the nut 45 in translation without causing it to in rotation. When the desired position is reached, it is sufficient to tighten the locknut 62 against the sleeve 55 by using the hexagonal head 61, which has the effect of firmly immobilizing the assembly 40, and in particular the nut 45, on the rod 9. The adjustment of the longitudinal position of the assembly 40 relative to the rod 9 takes place without the nut 45 is rotated, which keeps the extension 54 in place in the guide 100 and avoids interference between adjacent stud members in a loom.

Les éléments 50 et 54 ont tous deux pour fonction de garantir le bon positionnement de la noix 45 par rapport à la fente 29 et, en variante, un seul de ces éléments peut être employé sur une noix d'un dispositif conforme à l'invention.The elements 50 and 54 both have the function of ensuring the proper positioning of the nut 45 with respect to the slot 29 and, as a variant, only one of these elements can be used on a nut of a device according to the invention.

L'invention présente l'avantage particulier que, dans le cas où un nombre restreint de cadres de lisses est utilisé pour le tissage d'une pièce d'étoffe, les tiges 9 qui ne sont pas associées à des cadres sont maintenues dans des positions sensiblement verticales par la coopération des extensions 54 et des guides 100, de telle sorte qu'elles ne peuvent pas tomber ou s'accrocher.The invention has the particular advantage that, in the case where a small number of heald frames are used for weaving a piece of fabric, the rods 9 which are not associated with frames are held in positions substantially vertical by the cooperation of the extensions 54 and guides 100, so that they can not fall or hang on.

Comme il ressort plus clairement de la figure 5, chaque guide 100 peut être monté sur un support 102 articulé autour d'un axe 103 par rapport à un élément 104 du bâti du métier M, ce qui permet d'envisager un mouvement F transversal par rapport à la direction X-X', c'est-à-dire un mouvement d'approche ou d'éloignement des guides 100 et des organes-tenons 40 du métier par rapport aux organes-mortaises 20 selon la direction Y-Y'.As is clear from the figure 5 each guide 100 may be mounted on a support 102 hinged about an axis 103 with respect to an element 104 of the frame of the loom M, which makes it possible to envisage a transverse movement F with respect to the direction X-X ', that is to say a movement of approach or removal of the guides 100 and the members-tenons 40 of the loom with respect to the mortise members 20 in the direction Y-Y '.

Bien entendu, un seul support 102 peut être utilisé pour tous les guides 100 d'un métier à tisser.Of course, a single support 102 can be used for all the guides 100 of a loom.

Comme cela ressort également de la figure 5, les rails de guidage 8 et 8' peuvent être supportés par le support 102 ce qui permet de faire pivoter chaque tige 9 sur la totalité de sa longueur.As is also apparent from the figure 5 , the guide rails 8 and 8 'can be supported by the support 102 which allows to rotate each rod 9 over its entire length.

D'autres modes de réglage de la position des organes-tenons selon la direction Y-Y' peuvent être envisagés, tels que des organes de manoeuvre à vis, par excentrique ou sur glissière.Other ways of adjusting the position of the members-posts in the Y-Y 'direction can be envisaged, such as actuators screw, eccentric or slider.

Dans tous les cas, un ensemble d'entraînement des cadres dans le métier à tisser conforme à l'invention permet une mise en place aisée et simultanée des organes-tenons associés aux éléments de transmission de mouvement dans les organes-mortaises associés à différents cadres, éventuellement avec l'assistance d'un moteur.In any case, a frame drive assembly in the loom according to the invention allows easy and simultaneous installation of the tenon members associated with the movement transmission elements in the mortise members associated with different frames. possibly with the assistance of a motor.

L'invention a été représentée avec une ratière positive, elle est bien entendu applicable avec une ratière négative, telle que connue, par exemple, de EP-A-0 297 003 et, plus généralement dans tout métier à tisser dans lequel les cadres de lisses doivent être mis en mouvement, par exemple avec une mécanique à cames.The invention has been shown with a positive dobby, it is of course applicable with a negative dobby, as known, for example, from EP-A-0 297 003 and more generally in any loom in which the heald frames must be set in motion, for example with a cam mechanism.
