Il est connu d'entraîner les cadres de lisses d'un métier à tisser au moyen d'actionneurs électriques, la liaison entre chaque cadre et l'actionneur associé étant assurée par une ou plusieurs bielles, sur un ou plusieurs leviers oscillants.It is known to drive the heddle frames of a loom by means of electric actuators, the connection between each frame and the associated actuator being provided by one or more connecting rods on one or more oscillating levers.

Dans certains dispositifs connus, un excentrique est associé à l'une au moins des bielles, ce qui permet de transformer un mouvement de rotation d'un moteur électrique en un mouvement de monte et baisse d'un cadre. Dans ce cas, une agrafe auxiliaire doit être prévue sur l'une des bielles ou l'un des leviers pour permettre une variation de l'amplitude du mouvement d'un cadre, c'est-à-dire le réglage de la foule du métier.In certain known devices, an eccentric is associated with at least one of the connecting rods, which makes it possible to transform a rotational movement of an electric motor into a movement of upward and downward movement of a frame. In this case, an auxiliary clip must be provided on one of the connecting rods or one of the levers to allow a variation of the amplitude of the movement of a frame, that is to say the adjustment of the crowd of the job.

Dans d'autres dispositifs connus ( EP-A-0 848 097 ), le moteur électrique est animé d'un mouvement rotatif oscillant, ce mouvement étant transmis à l'une des bielles de commande d'un cadre de lisses sans utilisation d'un excentrique. Il est possible de faire varier l'amplitude de la foule en jouant sur l'amplitude du mouvement oscillant du moteur.In other known devices ( EP-A-0 848 097 ), the electric motor is driven by an oscillating rotary movement, this movement being transmitted to one of the control rods of a heald frame without the use of an eccentric. It is possible to vary the amplitude of the crowd by varying the amplitude of the oscillating movement of the motor.

C'est à ce second type de dispositif qu'a plus particulièrement trait l'invention. Dans ce genre de dispositif, les matériels connus sont encombrants et le montage d'un dispositif de formation de la foule est long et complexe, tout particulièrement dans la mesure où il nécessite l'assemblage d'organes de réduction du mouvement et de moteurs électriques associés pour transformer le mouvement du rotor de chaque moteur en un mouvement dont la vitesse et l'amplitude sont compatibles avec la trajectoire souhaitée pour les cadres de lisses.It is to this second type of device that the invention more particularly relates. In this type of device, the known materials are cumbersome and the assembly of a device for forming the crowd is long and complex, especially insofar as it requires the assembly of movement reduction devices and electric motors. associated to transform the rotor movement of each motor into a movement whose speed and amplitude are compatible with the desired path for the heald frames.

Ce dispositif est caractérisé en ce que l'actionneur comprend un ensemble autonome incorporant un moteur électrique et un réducteur à roue creuse, l'arbre de sortie du moteur étant équipé d'un pignon en prise avec une denture interne de la roue creuse, alors que cette roue creuse est apte à entraîner en rotation, avec un mouvement d'oscillations, un arbre d'entraînement de la bielle précitée.In this spirit, the invention relates to a shedding device for a loom equipped with a at least one stringer frame which is actuated by a pulling system incorporating, for the or each frame, at least one transmission rod of a driving movement generated by an oscillating rotary electric actuator. This device is characterized in that the actuator comprises an autonomous assembly incorporating an electric motor and a hollow-wheel gear, the output shaft of the motor being equipped with a pinion meshing with an internal toothing of the hollow wheel, while that this hollow wheel is adapted to drive in rotation, with a movement of oscillations, a drive shaft of the aforementioned rod.

Grâce à l'invention, l'actionneur associé à chaque cadre de lisses constitue un matériel compact et pouvant être manipulé et installé de façon autonome, ce qui facilite la construction d'un dispositif de formation de la foule et les opérations de maintenance d'un métier à tisser équipé d'un tel dispositif.Thanks to the invention, the actuator associated with each heald frame is a compact and can be handled and installed independently, which facilitates the construction of a crowd forming device and maintenance operations of a loom equipped with such a device.

  • L'actionneur est équipé, sur la même face d'extrémité, de moyens de raccordement à un circuit de circulation d'un fluide de refroidissement.
  • La face d'extrémité de l'actionneur sur laquelle sont prévus les moyens de connexion et, éventuellement, les moyens de raccordement, est celle à partir de laquelle fait saillie l'arbre d'entraînement de la bielle de transmission de mouvement.

Le métier à tisser M représenté à la figure 1 comprend plusieurs cadres de lisse, dont un seul est représenté sur cette figure avec la référence C. Ce cadre C est équipé de lisses 10 dont les oeillets respectifs 11 sont traversés par des fils de chaîne 12 se déplaçant dans le sens de la flèche F1.The loom M represented at figure 1 comprises several frames of smooth, of which only one is shown in this figure with the reference C. This frame C is equipped with rails 10 whose respective eyelets 11 are traversed by warp son 12 moving in the direction of the arrow F 1 .

Le cadre C est animé d'un mouvement d'oscillations verticales dans le sens de la double flèche F2. Ce mouvement est commandé par des bielles dont une seule est visible à la figure 1 avec la référence 20 qui sont attelées en partie basse du cadre C ainsi que sur deux leviers oscillants 22. Ces leviers 22 sont reliés entre eux par une bielle 24, alors que l'un des leviers 22 est relié par une bielle 26 à un maneton 28 monté sur un arbre d'entraînement 30 constituant l'organe de sortie d'un actionneur rotatif électrique 40.The frame C is animated by a movement of vertical oscillations in the direction of the double arrow F 2 . This movement is controlled by connecting rods, only one of which is visible at figure 1 with the reference 20 which are hitched in the lower part of the frame C and two oscillating levers 22. These levers 22 are interconnected by a connecting rod 24, while one of the levers 22 is connected by a connecting rod 26 to a crank pin 28 mounted on a drive shaft 30 constituting the output member of an electric rotary actuator 40.

Cet actionneur 40 est monté sur une platine support 80. En pratique, et comme représenté en traits mixtes aux figures 1 et 2, la platine est prévue suffisamment large pour lui permettre de supporter un ou plusieurs autres actionneurs 40' du type de l'actionneur 40. Le nombre d'actionneurs 40 est adapté en fonction du nombre de cadres C à entraîner.This actuator 40 is mounted on a support plate 80. In practice, and as shown in phantom with the figures 1 and 2 , the plate is provided wide enough to allow it to support one or more other actuators 40 'of the type of the actuator 40. The number of actuators 40 is adapted according to the number of C frames to be driven.

L'actionneur 40 est pourvu de deux orifices, dont un seul est visible à la figure 2 avec la référence 41, qui sont alignés avec des orifices 81 prévus sur la platine 80, ce qui permet le passage de vis de fixation dont une seule est visible avec la référence 43, la seconde étant repérée par son trait d'axe X43. Des écrous 43a sont prévus pour immobiliser les vis 43 et équivalentes dans les orifices 41 et 81.The actuator 40 is provided with two orifices, only one of which is visible at the figure 2 with the reference 41, which are aligned with orifices 81 provided on the plate 80, which allows the passage of fixing screws of which only one is visible with the reference 43, the second being identified by its X axis line 43 . Nuts 43a are provided for immobilize the screws 43 and equivalents in the orifices 41 and 81.

Ainsi qu'il ressort plus particulièrement des figures 2 à 4, l'actionneur 40 comprend un corps 42 allongé selon une direction A-A' correspondant à un axe de rotation d'un rotor 44 appartenant à un moteur électrique 46. Le rotor 44 forme l'arbre de sortie du moteur 46.As is clear from the Figures 2 to 4 , the actuator 40 comprises a body 42 elongate in a direction AA 'corresponding to an axis of rotation of a rotor 44 belonging to an electric motor 46. The rotor 44 forms the output shaft of the motor 46.

On note 48 le stator du moteur 46, ce stator étant disposé radialement autour de la partie principale du rotor 44. Le rotor 44 est supporté par rapport au corps 42 grâce à des paliers 44a et 44b.It is noted 48 the motor stator 46, the stator being arranged radially around the main part of the rotor 44. The rotor 44 is supported relative to the body 42 through bearings 44 a and 44 b.

Par rapport à la partie médiane du rotor 44 située entre les paliers, le rotor se prolonge jusqu'au niveau d'un système de frein 50 commandé électriquement et connu en soi.With respect to the middle portion of the rotor 44 located between the bearings, the rotor extends to the level of a brake system 50 electrically controlled and known per se.

On note 44c l'extrémité du rotor 44 disposé au niveau du frein 50.We denote the end 44 c of the rotor 44 disposed at the brake 50.

Au niveau de son extrémité 44d opposée à l'extrémité 44c, le rotor 44 est monobloc avec un pignon 52. En variante, le pignon 52 peut être rapporté sur le rotor 44. Ce pignon 52 est pourvu d'une denture externe 52a adaptée pour coopérer avec une denture interne 54a d'une roue creuse 54 qui est monobloc avec l'arbre d'entraînement 30. La denture 54a est ménagée sur la surface radiale interne d'un secteur 54b fixé sur la partie principale 54c de la roue 54 au moyen de vis, dont une seule est visible à la figure 3, avec la référence 55.At its end 44 opposite to the end 44 c, the rotor 44 is integral with a gear 52. Alternatively, the pinion 52 may be attached to the rotor 44. This pinion 52 is provided with an external toothing 52 is adapted to cooperate with an internal toothing 54 has a hollow wheel 54 which is integral with the drive shaft 30. the teeth 54 a is formed on the inner radial surface of a sector 54 b fixed to the main part 54 c of the wheel 54 by means of screws, of which only one is visible in the figure 3 , with the reference 55.

En variante, la roue creuse 54 pourrait être rapportée sur l'arbre 30 et assemblée à celui-ci par tout moyen approprié. Selon une autre variante, le secteur 54b pourrait être monobloc avec la partie principale 54c.Alternatively, the hollow wheel 54 could be attached to the shaft 30 and assembled thereto by any suitable means. According to another variant, the sector 54 b could be monobloc with the main part 54 c .

Des paliers 30a et 30b supportent l'arbre 30 et la roue creuse 54 par rapport au reste de l'actionneur 40.Bearings 30a and 30b support the shaft 30 and the ring gear 54 relative to the remainder of the actuator 40.

Les éléments 52 et 54 sont disposés à l'intérieur d'un boîtier 56 fermé par un capot 58, de telle sorte qu'il est formé, entre le palier 44b et le capot 58, un volume fermé V56 dans lequel est retenu prisonnier un lubrifiant, tel que de l'huile, et dans lequel les éléments 52 et 54 constituent un réducteur 60 du mouvement rotatif oscillant du rotor 44, ce qui permet de commander le mouvement rotatif oscillant de l'arbre 30 et, par là même, celui des leviers basculants 22 et le mouvement oscillant du cadre C dans le sens de la double flèche F2.The elements 52 and 54 are disposed within a housing 56 closed by a cover 58, so that it is formed between the bearing 44b and the cover 58, an enclosed volume 56 wherein V is selected trapped a lubricant, such as oil, and in which the elements 52 and 54 constitute a reduction gear 60 of the oscillating rotary movement of the rotor 44, which makes it possible to control the oscillating rotary motion of the shaft 30 and thereby , that of the rocking levers 22 and the oscillating movement of the frame C in the direction of the double arrow F 2 .

Grâce à l'invention, le mouvement rotatif oscillant F3 du rotor 44 est transmis, grâce aux organes 52 et 54, à l'arbre 30 qui est ainsi animé d'un mouvement de même nature F4. Ce mouvement est transmis par le maneton 28 à la bielle 26 qui a un mouvement F5 lui-même transmis par les leviers 22 et les bielles 20 et 26 au cadre C qui a le mouvement F2.Thanks to the invention, the oscillating rotary movement F 3 of the rotor 44 is transmitted, thanks to the members 52 and 54, to the shaft 30 which is thus driven by a movement of the same nature F 4 . This movement is transmitted by the crankpin 28 to the rod 26 which has a movement F 5 itself transmitted by the levers 22 and the rods 20 and 26 to the frame C which has the movement F 2 .

Il est à noter que l'amplitude et la vitesse du mouvement F2, c'est-à-dire de la foule, sont aisément réglables en jouant l'amplitude et la vitesse du mouvement F3.It should be noted that the amplitude and the speed of the movement F 2 , that is to say of the crowd, are easily adjustable by varying the amplitude and the speed of the movement F 3 .

On note 40a la face d'extrémité de l'actionneur 40 à partir de laquelle l'arbre 30 fait saillie au-delà du capot 58.40 is noted at the end face of the actuator 40 from which the shaft 30 protrudes beyond the cover 58.

L'actionneur 40 est pourvu, au niveau de cette face 40a, d'un connecteur 72 destiné à permettre le raccordement de l'actionneur 40 sur un connecteur 82 de forme correspondante porté par la platine 80 et raccordé à une ligne 82a d'alimentation en courant électrique de l'actionneur 40. Le connecteur 82 est prévu sur la face 80a de la platine 80 contre laquelle vient en appui la face 40a lorsque l'actionneur est monté sur la platine.The actuator 40 is provided at this face 40a with a connector 72 intended to allow the connection of the actuator 40 to a connector 82 of corresponding shape carried by the plate 80 and connected to a supply line 82a. electrical current of the actuator 40. The connector 82 is provided on the face 80a of the plate 80 against which bears the face 40a when the actuator is mounted on the plate.

De même, l'actionneur 40 est équipé d'un second connecteur 74 destiné à être raccordé sur un connecteur 84 de forme correspondante, également prévu sur la face 80a de la platine 80. Le connecteur 84 est relié par une ligne 84a à des moyens non représentés de contrôle/commande de l'actionneur 40.Similarly, the actuator 40 is equipped with a second connector 74 intended to be connected to a connector 84 of corresponding shape, also provided on the face 80a of the plate 80. The connector 84 is connected by a line 84a to unrepresented means for controlling / controlling the actuator 40.

Les connecteurs 72 et 74 sont suffisamment distants les uns des autres pour éviter tout risque de perturbation. En variante, les connecteurs 72 et 74 pourraient être regroupés sous la forme d'un seul connecteur, certains fils conducteurs étant alors blindés pour éviter les perturbations.The connectors 72 and 74 are sufficiently distant from each other to avoid any risk of disturbance. As a variant, the connectors 72 and 74 could be grouped together as a single connector, some of the conducting wires being then shielded to avoid disturbances.

La platine 80 est pourvue d'un orifice 85 de passage de l'extrémité de l'arbre 30 sur laquelle est montée le maneton 28.The plate 80 is provided with an orifice 85 for the passage of the end of the shaft 30 on which the crankpin 28 is mounted.

Deux orifices 76 et 78 ménagés sur la face 40a sont destinés à coopérer avec des organes de raccordement mâles 86, respectivement 88, prévus sur la face 80a de la platine 80 pour permettre la circulation vers l'intérieur du corps 42 d'un fluide caloporteur de refroidissement du moteur 46. En effet, un circuit 46a de circulation de fluide caloporteur est prévu dans le boîtier 42, notamment entre le stator 48 et le corps 42.Two orifices 76 and 78 formed on the face 40a are intended to cooperate with male connecting members 86, 88 respectively provided on the face 80a of the plate 80 to allow the circulation in the body 42 of a coolant In fact, a coolant circulation circuit 46a is provided in the housing 42, in particular between the stator 48 and the body 42.

A la figure 2, les flèches F6 et F7 représentent le sens de circulation du fluide caloporteur.To the figure 2 the arrows F 6 and F 7 represent the flow direction of the coolant.

Ainsi, par le montage de l'actionneur 40 sur la platine 80, on peut réaliser, en une opération, l'alimentation en puissance du moteur 46, le contrôle électrique de l'actionneur 40 et son raccordement au circuit de refroidissement.Thus, by mounting the actuator 40 on the plate 80, one can realize, in one operation, the power supply of the motor 46, the electrical control of the actuator 40 and its connection to the cooling circuit.

En outre, le nombre d'actionneurs peut être aisément et rapidement adapté au nombre de cadres à entraîner. De même, les opérations de maintenance sont facilitées, notamment l'échange standard d'un ou plusieurs actionneurs.In addition, the number of actuators can be easily and quickly adapted to the number of frames to train. Similarly, the maintenance operations are facilitated, including the standard exchange of one or more actuators.
