Both motors (15, 16) are supplied in parallel by one or more frequency converters (30) and are linked together by synchronizing means.

Description

METIER A TISSER.LOOM.
La présente invention concerne un perfectionnement apporté aux métiers à tisser, et plus particulièrement sur une nouvelle manière d'assurer l'entraînement et la synchronisation entre les différents moyens que comporte le métier pour réaliser un tissu.The present invention relates to an improvement made to weaving looms, and more particularly to a new way of ensuring training and synchronization between the different means that the loom has for producing a fabric.
Dans la suite de la description, l'invention sera décrite pour un métier à tisser dans lequel l'insertion de la trame est réalisée par l'intermédiaire de deux pinces, introduites simultanément à l'intérieur de la foule à partir de chaque côté du métier, l'une servant à amener le fil de trame prélevé sur une bobine située sur un côté de la machine jusqu'au milieu de sa largeur où s'effectue alors un transfert à la seconde pince qui, lors de son recul, amène le fil sur le côté opposé au côté d'alimentation, les déplacements desdites pinces à l'intérieur de la foule étant assurés par un ensemble désigné couramment par l'expression "lance ou ruban flexible".In the following description, the invention will be described for a weaving loom in which the insertion of the weft is carried out by means of two pliers, introduced simultaneously inside the crowd from each side of the loom, one used to bring the weft yarn taken from a spool located on one side of the machine to the middle of its width where a transfer is then made to the second clamp which, during its retraction, brings the wire on the side opposite the supply side, the movements of said clamps inside the crowd being ensured by an assembly commonly designated by the expression "flexible lance or ribbon".
Il est évident que cela n'est pas limitatif et que l'invention pourrait également être appliquée à d'autres types de métier à tisser utilisant d'autres moyens que des pinces positives pour assurer l'insertion de la trame.It is obvious that this is not limiting and that the invention could also be applied to other types of weaving loom using means other than positive clamps to ensure the insertion of the weft.
La réalisation d'un tissu implique : - d'une part, d'assurer le déroulement de la nappe de fils de chaine, la formation de la foule et le renvidage du tissu réalisé et ;The production of a fabric involves: - on the one hand, ensuring the unwinding of the web of warp threads, the formation of the crowd and the winding of the fabric produced and;
- d'autre part, d'inserrer le fil de trame lorsque la foule est ouverte et de le tasser contre la dernière duite réalisée par l'intermédiaire d'un peigne porté par un battant. A ce jour, pour réaliser la commande et la synchronisation des différents éléments permettant de réaliser ces opérations, les métiers à tisser comportent un moteur unique qui, par l'intermédiaire d'un ensemble embrayage/frein, entraîne en rotation un arbre moteur dit "arbre principal" qui s'étend sur toute la largeur du métier et à partir duquel des liaisons mécaniques permettent d'assurer l'entraînement en synchronisme des différents organes du métier.- on the other hand, to insert the weft thread when the crowd is open and to pack it against the last pick made by means of a comb carried by a leaf. To date, to carry out the control and synchronization of the various elements making it possible to carry out these operations, the weaving looms comprise a single motor which, by means of a clutch / brake assembly, drives in rotation a motor shaft called " main shaft "which extends over the entire width of the loom and from which mechanical connections make it possible to ensure synchronous training of the various organs of the loom.
D'un point de vue pratique, une telle conception donne satisfaction, mais elle présente cependant comme inconvénients de nécessiter un moteur de grande puissance, pouvant transmettre un couple important qui, à titre indicatif, est de l'ordre de 70 m.kg pour un métier à tisser permettant d'obtenir des articles ayant une largeur de 2 à 4 mètres, et tournant à une vitesse de 400 à 500 coups/min.From a practical point of view, such a design is satisfactory, but it has the disadvantages of requiring a high power motor, which can transmit a significant torque which, for information, is of the order of 70 m.kg for a loom making it possible to obtain articles having a width of 2 to 4 meters, and turning at a speed of 400 to 500 strokes / min.
Par ailleurs, la transmission du mouvement aux différents organesFurthermore, the transmission of movement to the various organs
(ensouple de fils de chaine, système de renvidage, avance et recul des pinces d'insertion, commande du battant) faisant appel à des transmissions mécaniques complique notablement la structure de ces métiers.(warp of warp wires, winding system, advance and retreat of the insertion clamps, control of the leaf) using mechanical transmissions considerably complicates the structure of these trades.
Or on a trouvé, et c'est ce qui fait l'objet de la présente invention, une solution qui permet de résoudre l'ensemble de ces problèmes.Now we have found, and this is what is the subject of the present invention, a solution which makes it possible to solve all of these problems.
D'une manière générale, l'invention concerne donc un perfectionnement apporté aux métiers à tisser dans lesquels l'insertion de la trame est réalisée par l'intermédiaire de deux pinces, introduites simultanément à l'intérieur de la foule à partir de chaque côté du métier, l'une servant à amener le fil de trame prélevé sur une bobine située sur un côté de la machine jusqu'au milieu de sa largeur où s'effectue alors un transfert à la seconde pince qui, lors de son recul, amène le fil sur le côté opposé au côté d'alimentation, la duite mise en place étant ensuite tassée contre la dernière duite du tissu par l'intermédiaire d'un peigne porté par un battantIn general, the invention therefore relates to an improvement made to weaving looms in which the insertion of the weft is carried out by means of two pliers, introduced simultaneously inside the crowd from each side. of the trade, one used to bring the weft yarn taken from a spool located on one side of the machine to the middle of its width where a transfer is then made to the second clamp which, during its retraction, brings the thread on the opposite side to the feeding side, the pick placed then being pressed against the last pick of the fabric by means of a comb carried by a leaf
L'invention se caractérise en ce que la commande des moyens d'insertion de trame et du battant est réalisée par l'intermédiaire de deux moteurs électriques, disposés de chaque côté du métier :The invention is characterized in that the control of the weft insertion means and of the leaf is carried out by means of two electric motors, arranged on each side of the loom:
- chaque moteur entraînant un arbre machine commandant les moyens d'insertion de trame et le carter porte battant situé du même côté que lui ;each motor driving a machine shaft controlling the weft insertion means and the swing door casing situated on the same side as it;
- ces deux moteurs étant alimentés en parallèle par l'intermédiaire d'un ou plusieurs convertisseur(s) de fréquence et étant reliés entre eux par des moyens de synchronisation ; de tels moyens de synchronisation sont de manière simple constitués par une connexion rigide reliant entre eux les deux arbres machines.- These two motors being supplied in parallel via one or more frequency converter (s) and being interconnected by synchronization means; such synchronization means are simply constituted by a rigid connection connecting together the two machine shafts.
S'il peut être envisagé d'assurer la commande d'une part du dérouleur de chaîne, de l'enrouleur de tissu, d'autre part du déplacement des cadres assurant la formation de la foule par l'intermédiaire de liaisons mécaniques avec les deux arbres moteurs précités, selon une forme préférentielle de réalisation conforme à l'invention, chacun de ces éléments est également commandé par un moteur électrique. Dans un tel cas, la synchronisation de l'ensemble des moteurs que comporte le métier à tisser est obtenue par l'intermédiaire d'une unité centrale de commande. Grâce à une telle conception dans laquelle on réalise la commande des différents organes du métier à tisser par des moteurs spécifiques associés à chaque moyen, il est possible non seulement d'éliminer un grand nombre de liaisons mécaniques que nécessitent les métiers conventionnels dans lesquels tous les mouvements sont pris à partir d'un arbre principal commandé par un moteur unique, mais également d'obtenir une montée en vitesse beaucoup plus rapide du métier le couple à transmettre étant beaucoup plus faible.If it can be envisaged to control on the one hand the chain unwinder, the fabric reel, on the other hand the movement of the frames ensuring the formation of the crowd through mechanical connections with the two aforementioned drive shafts, according to a preferred embodiment according to the invention, each of these elements is also controlled by an electric motor. In such a case, the synchronization of all the motors included in the loom is obtained by means of a central control unit. Thanks to such a design in which the various organs of the weaving loom are controlled by specific motors associated with each means, it is possible not only to eliminate a large number of mechanical connections that require the conventional looms in which all the movements are taken from a main shaft controlled by a single motor, but also to obtain a much faster speed increase in the loom, the torque to be transmitted being much lower.
L'invention et les avantages qu'elle apporte seront cependant mieux compris grâce à l'exemple de réalisation donné ci-après à titre indicatif mais non limitatif, et qui est illustré par la figure unique qui est une vue schématique, en perspective d'un métier à tisser réalisé conformément à l'invention.The invention and the advantages which it brings will however be better understood thanks to the embodiment given below for information but not limitation, and which is illustrated by the single figure which is a schematic view, in perspective of a loom produced in accordance with the invention.
En se reportant au schéma annexé, le métier à tisser conforme à l'invention se compose donc, comme tous les métiers à tisser, d'une ensouple (1) de fils de chaîne (2), de cadres de lisses (3) (un seul étant schématisé) ou système Jacquard de commande des fils de chaîne, permettant d'assurer la formation de la foule (4), d'un système d'appel (5) du tissu (6) formé et d'un rouleau de renvidage (7) dudit tissu.Referring to the appended diagram, the weaving loom according to the invention therefore consists, like all weaving looms, of a beam (1) of warp threads (2), heddle frames (3) ( only one being shown diagrammatically) or Jacquard system for controlling the warp threads, making it possible to ensure the formation of the crowd (4), a system for calling up the fabric (6) formed and a roll of winding (7) of said fabric.
La commande des fils de chaine est obtenue par tous moyens appropriés, tels que par exemple une ratière (8) ou une mécanique Jacquard. La trame (9) est stockée sur une bobine disposée sur un côté du métier. Bien entendu, le métier peut être conçu pour permettre l'insertion, selon un rythme fonction du tissu à réaliser, d'une pluralité de trames de couleurs et/ou natures différentes. Dans un tel cas, l'alimentation en fils de trame peut être réalisée conformément aux enseignements du FR-A-2 695 414.The control of the warp threads is obtained by any appropriate means, such as for example a dobby (8) or a Jacquard machine. The weft (9) is stored on a reel arranged on one side of the loom. Of course, the loom can be designed to allow the insertion, at a rate depending on the fabric to be produced, of a plurality of wefts of different colors and / or natures. In such a case, the weft feed can be carried out in accordance with the teachings of FR-A-2 695 414.
L'insertion du fil de trame (9) est obtenu par l'intermédiaire d'un ensemble comprenant deux pinces positives (10,11), disposées de chaque côté du métier et introduites simultanément à l'intérieur de la foule (4), la pince (10) entraînant le fil de trame (9) et transférant cette extrémité de ce dernier à la pince (11) au milieu de la foule par l'intermédiaire de moyens de transfert (35), cette pince (11) amenant la trame de l'autre côté du métier. Le tassement de la trame introduite contre la dernière duite du tissu (6) est réalisé par l'intermédiaire d'un peigne (12) monté sur un battant commandé par deux carters (13,14).The insertion of the weft thread (9) is obtained by means of an assembly comprising two positive clamps (10,11), arranged on each side of the loom and introduced simultaneously inside the crowd (4), the clamp (10) driving the weft thread (9) and transferring this end of the latter to the clamp (11) in the middle of the crowd by means of transfer means (35), this clamp (11) bringing the frame on the other side of the loom. The compaction of the weft introduced against the last pick of the fabric (6) is carried out by means of a comb (12) mounted on a leaf controlled by two casings (13,14).
Tous les moyens précités étant des moyens conventionnels, ils ne seront donc pas décrits en détail par mesure de simplification.All the aforementioned means being conventional means, they will therefore not be described in detail for the sake of simplification.
Conformément à l'invention, la commande des moyens (10,11) permettant l'insertion de la trame (9) ainsi que celle du peigne (4) porté par le battant, est réalisée par l'intermédiaire de deux moteurs électriques (15,16) disposés de chaque côté du métier. Le moteur (15) entraîne l'arbre machine (17) qui commande les moyens (28) (boites à cames) commandant les déplacements de la pince d'insertion (10), le carter (13) porte battant situé du côté du gauche du métier et éventuellement la mécanique de formation de la foule ; le moteur (16) situé du côté droit entraînant un second arbre (18) ainsi que les moyens (19) (boites à cames) commandant les déplacements de la pince (11) et le carter (14) porte battant.According to the invention, the control of the means (10,11) allowing the insertion of the frame (9) as well as that of the comb (4) carried by the leaf, is carried out by means of two electric motors (15 , 16) arranged on each side of the loom. The motor (15) drives the machine shaft (17) which controls the means (28) (cam boxes) controlling the movements of the insertion clamp (10), the casing (13) swing door located on the left side of the trade and possibly the mechanics of crowd training; the motor (16) located on the right side driving a second shaft (18) as well as the means (19) (cam boxes) controlling the movements of the clamp (11) and the casing (14) swing door.
Ces deux moteurs (15,16) sont par exemple des moteurs du type asynchrone. Ils sont alimentés en parallèle par l'intermédiaire d'un convertisseur de fréquences (30) et sont reliés entre eux par des moyens de synchronisation. Eventuellement, chaque moteur pourrait être alimenté par un convertisseur de fréquence.These two motors (15,16) are for example motors of the asynchronous type. They are supplied in parallel via a frequency converter (30) and are interconnected by synchronization means. Optionally, each motor could be powered by a frequency converter.
Dans l'exemple de réalisation illustré par le schéma annexé, de tels moyens de synchronisation sont constitués par une connexion rigide (20) reliant entre eux les deux arbres (17,18).In the embodiment illustrated by the attached diagram, such synchronization means are constituted by a rigid connection (20) connecting the two shafts (17,18) to each other.
Par ailleurs, dans l'exemple illustré, l'ensouple (1) et le système d'appel (5) du tissu formé sont commandés par deux moteurs individuels (21) et (22).Furthermore, in the example illustrated, the beam (1) and the call system (5) of the fabric formed are controlled by two individual motors (21) and (22).
Enfin, s'il peut être envisagé de commander des organes de formation de la foule, ratière par exemple, par une liaison mécanique (courroie (23) /arbre (24)), selon une forme préférentielle de mise en oeuvre, cette commande est obtenue par un moteur individuel (25). La mise en oeuvre d'un tel métier est la suivante.Finally, if it can be envisaged to order members for forming the crowd, dobby for example, by a mechanical connection (belt (23) / shaft (24)), according to a preferred form of implementation, this command is obtained by an individual motor (25). The implementation of such a trade is as follows.
Lors de la mise en route du métier, les différents organes étant à leur point de départ, on procède à une montée en vitesse des moteurs (15,16) sur plusieurs tours du métier, le dérouleur (21), l'appel (22) et la ratière (8) étant à l'arrêt, puis on présente la trame (9) à la pince d'insertion (10), et simultanément, on actionne les moteurs (21,22,25) permettant un processus normal de tissage.When starting up the loom, the various organs being at their starting point, the engines (15,16) are speeded up over several turns of the loom, the unwinder (21), the call (22 ) and the dobby (8) being stopped, then the weft (9) is presented to the insertion clamp (10), and simultaneously, the motors (21,22,25) are activated allowing a normal process of weaving.
Suite à un arrêt, volontaire ou consécutif à une casse lors de la remise en route, après réparation éventuelle du fil, l'ensemble des moteurs est actionné pour réaliser un retour en arrière de deux tours. Cela étant fait, les moteurs (15,16) sont mis en route et accélérés sur un tour puis, au deuxième tour, on inserre une nouvelle duite (9) et, simultanément, on réactionne les moteurs (21,22,25) commandant le dérouleur de chaîne et la ratière.Following a stop, voluntary or consecutive to a breakage during the restarting, after possible repair of the wire, all the motors are actuated to carry out a reversal of two turns. This being done, the engines (15,16) are started and accelerated on one turn then, on the second turn, a new pick (9) is inserted and, simultaneously, the engines (21,22,25) are reacted the chain unwinder and the dobby.
Par rapport aux solutions antérieures dans lesquelles les mouvements sont obtenus à partir d'un seul moteur entraînant un arbre unique à partir duquel les liaisons mécaniques permettent d'assurer l'entraînement en synchronisme des différents organes du métier, la solution conforme à l'invention présente les avantages suivants :Compared to previous solutions in which the movements are obtained from a single motor driving a single shaft from which the mechanical connections make it possible to ensure the synchronous training of the various organs of the trade, the solution according to the invention has the following advantages:
- montée en vitesse plus rapide ;- faster increase in speed;
- structure générale du métier plus simple par la suppression de l'arbre principal à fort couple, de l'ensemble cellule embrayage-frein, et du moteur de rappel sur la mécanique de formation de la foule ;- general structure of the profession simpler by removing the main shaft with high torque, the clutch-brake cell assembly, and the return motor on the crowd training mechanics;
- une plus grande fiabilité et une diminution des vibrations ;- greater reliability and less vibration;
- un ajustage de la machine et une marche lente intégrée. - machine adjustment and integrated slow running.
