Abstract

The machine comprises two sections (2, 3) and at least one pair of mutually opposed cam carriers (4, 5). These cam carriers are independent and are driven individually, for example by means of notched belts (10, 13) and motors (12, 15). The omission of the bow of the carriage makes it possible to arrange a large number of bars (17 to 22) for individually driven yarn guides. The yarns arrive at the yarn guides by the shortest route and the working speed can be increased considerably. <IMAGE>

Description

La présente invention a pour objet une machine à tricoter rectiligne comprenant deux fontures, au moins une paire de porte-cames opposées pour l'entraînement des aiguilles, des moyens d'entraînement de ces porte-cames le long des fontures, plusieurs guide-fil susceptibles de se déplacer sur des barres au-dessus des fontures, des moyens d'entraînement de ces guide-fil et des moyens de commande des déplacements des porte-cames et des guide-fil.The subject of the present invention is a straight knitting machine comprising two needle beds, at least one pair of opposite cam holders for driving the needles, means for driving these cam holders along the needle beds, several thread guides. likely to move on bars above the needle beds, means for driving these thread guides and means for controlling the movements of the cam holders and thread guides.

Une telle machine est connue, par exemple, de la demande de brevet EP 0 246 364. Dans cette machine, comme dans toutes les machines connues, les porte-cames sont montés sur un chariot en forme d'arceau chevauchant les fontures et les barres-rageurs sur lesquelles se déplacent les guide-fil. Une telle forme de chariot est utilisée pratiquement depuis l'invention des machines à tricoter à deux fontures et elle a été considérée jusqu'ici comme une conception obligatoire, afin d'assurer le déplacement synchronisé des deux porte-cames, malgré les inconvénients qu'elle présente pour une machine à tricoter des tricots Intarsia. Ces inconvénients résident dans le fait que les fils à tricoter doivent être amenés aux guide-fil presque horizontalement pour ne pas se trouver dans la trajectoire du chariot. A cet effet les fils doivent passer sur des renvois à l'une des extrémités de la machine. Il en résulte que pour un sens de déplacement du chariot la traction sur le fil est importante, tandis que lors du déplacement du chariot dans l'autre sens, le fil doit être retiré dans l'autre sens afin que le mou produit sur le fil ne provoque pas la chute du fil sur les fontures. Ces conditions, qui ont du être respectées jusqu'ici, limitent la vitesse de déplacement du chariot, ainsi que le nombre de fils de couleurs différentes susceptibles d'être tricotés. Or, les performances actuelles des moyens électroniques et mécaniques sont telles que, sans ces inconvénients, il serait sans autre possible de travailler à une vitesse sensiblement plus grande que la vitesse actuelle et avec davantage de fils.Such a machine is known, for example, from patent application EP 0 246 364. In this machine, as in all known machines, the cam holders are mounted on a carriage in the form of an arch overlapping the needle beds and the bars. -rageurs on which the wire guides move. Such a form of carriage has been used practically since the invention of knitting machines with two needle beds and has hitherto been considered as a compulsory design, in order to ensure the synchronized movement of the two cam holders, despite the drawbacks that it presents for an Intarsia knitting machine. These drawbacks lie in the fact that the knitting yarns must be brought to the yarn guides almost horizontally so as not to be in the path of the carriage. For this purpose, the wires must pass over references at one end of the machine. It follows that for a direction of movement of the carriage the traction on the wire is important, while during the displacement of the carriage in the other direction, the wire must be withdrawn in the other direction so that the slack produced on the wire does not cause the thread to fall on the needle beds. These conditions, which have had to be observed so far, limit the speed of movement of the carriage, as well as the number of threads of different colors capable of being knitted. However, the current performance of electronic and mechanical means is such that, without these drawbacks, it would be without other possibility to work at a speed substantially greater than the current speed and with more son.

Dans les années 1920 la maison Dubied a cherché à résoudre ce problème en rallongeant l'arc de chariot transversalement. L'arc de chariot s'étendait dans le prolongement de la machine, en augmentant considérablement l'encombrement de la machine.In the 1920s, the Dubied company sought to solve this problem by extending the carriage arc transversely. The carriage arc extended in the extension of the machine, considerably increasing the size of the machine.

La présente invention a pour but d'obvier aux inconvénients décrits ci-dessus et de proposer une construction permettant d'augmenter considérablement la vitesse de travail de la machine, ainsi que le nombre de fils tricotés.The object of the present invention is to obviate the drawbacks described above and to propose a construction making it possible to considerably increase the working speed of the machine, as well as the number of knitted threads.

La machine à tricoter selon l'invention est caractérisée en ce que les porte-cames de chaque paire sont indépendants et qu'ils sont entraînés individuellement et mutuellement asservis.The knitting machine according to the invention is characterized in that the cam holders of each pair are independent and that they are driven individually and mutually controlled.

La machine à tricoter selon l'invention ne comporte donc pratiquement plus de chariot et, contrairement aux idées acquises, une synchronisation des porte-cames est parfaitement possible sans liaison rigide entre ces porte-cames.The knitting machine according to the invention therefore practically no longer has a carriage and, contrary to the ideas acquired, synchronization of the cam holders is perfectly possible without rigid connection between these cam holders.

L'asservissement mutuel des porte-cames peut être assuré par des moyens mécaniques ou électroniques.The mutual control of the cam holders can be ensured by mechanical or electronic means.

Jusqu'ici, un chariot semblait également nécessaire pour assurer l'alignement transversal des porte-cames. Or, il s'avère que les porte-cames ne doivent pas être nécessairement alignés transversalement, mais qu'il peut être au contraire judicieux de les décaler, par exemple pour serrer ou desserrer les mailles à volonté. La machine à tricoter selon l'invention permet précisément de décaler les porte-cames à volonté. Cette faculté ouvre d'immenses possibilités de tricotage et donne une très grande souplesse d'utilisation.Until now, a carriage also seemed necessary to ensure the transverse alignment of the cam holders. However, it turns out that the cam holders do not necessarily have to be transversely aligned, but that it may on the contrary be wise to offset them, for example to tighten or loosen the meshes at will. The knitting machine according to the invention makes it possible precisely to shift the cam holders at will. This ability opens up immense knitting possibilities and gives great flexibility of use.

Dans une telle machine à tricoter, les guide-fil sont de préférence entraînés individuellement, chacun par son propre moteur, ce qui permet de positionner les guide-fil à volonté et partant la réalisation de nouvelles structures de mailles, ainsi que la combinaison de différentes structures et d'Intarsia.In such a knitting machine, the thread guides are preferably driven individually, each by its own motor, which makes it possible to position the thread guides at will and therefore the creation of new mesh structures, as well as the combination of different structures and Intarsia.

Le dessin annexé représente, à titre d'exemple, une forme d'exécution de l'invention.The accompanying drawing shows, by way of example, an embodiment of the invention.

La figure 1 représente schématiquement une vue de face d'une machine à tricoter.Figure 1 schematically shows a front view of a knitting machine.

La figure 2 est une vue en coupe selon II-II de la figure 1.Figure 2 is a sectional view along II-II of Figure 1.

La machine à tricoter représentée comprend, comme les machines usuelles, un bâti 1 portant deux fontures 2 et 3 montées en V. Dans chacune des fontures 2 et 3 sont disposées des aiguilles et des clavettes dont l'entraînement est assuré par deux porte-cames 4 et 5, à double chute dans l'exemple considéré.The knitting machine shown comprises, like the usual machines, a frame 1 carrying two needle beds 2 and 3 mounted in V. In each needle beds 2 and 3 are arranged needles and keys which are driven by two cam holders 4 and 5, double fall in the example considered.

Dans leur nouvelle conception, les porte-cames 4 et 5 ne sont pas montés sur un chariot, mais sont indépendants. Le porte-cames 4 est monté coulissant sur deux barres parallèles 6 et 7. De manière analogue, le porte-cames 5 est monté sur deux barres parallèles cylindriques 8 et 9. Le porte-cames 4 est attaché à une courroie crantée 10 s'étendant sur presque toute la longueur de la machine. La courroie crantée 10 est entraînée par une roue dentée 11 elle-même entraînée par un premier moteur électrique 12. De manière analogue, le porte-cames 5 est attaché à une seconde courroie crantée 13 entraînée par une roue dentée 14 elle-même entraînée par un second moteur 15. A l'autre extrémité de la machine, les courroies crantées passent sur des renvois 16. Ces renvois peuvent être également dentés. De manière à avoir deux courroies crantées 10 et 13 parfaitement identiques, ces courroies sont de préférence obtenues par le partage en long d'une courroie crantée. Les courroies obtenues sont ainsi parfaitement identiques, tant dans leur forme que dans leur structure. Elles présentent donc notamment les mêmes caractéristiques d'élasticité.In their new design, the cam holders 4 and 5 are not mounted on a carriage, but are independent. The cam holder 4 is slidably mounted on two parallel bars 6 and 7. Similarly, the cam holder 5 is mounted on two parallel cylindrical bars 8 and 9. The cam holder 4 is attached to a toothed belt 10 s' extending over almost the entire length of the machine. The toothed belt 10 is driven by a toothed wheel 11 which is itself driven by a first electric motor 12. Similarly, the cam holder 5 is attached to a second toothed belt 13 driven by a toothed wheel 14 which is itself driven by a second motor 15. At the other end of the machine, the toothed belts pass over references 16. These references can also be toothed. So as to have two perfectly identical toothed belts 10 and 13, these belts are preferably obtained by sharing a notched belt along. The belts obtained are thus perfectly identical, both in shape and in structure. They therefore have in particular the same elasticity characteristics.

Au-dessus des fontures 2 et 3 s'étendent un certain nombre de barres, dans l'exemple représenté six barres 17, 18, 19, 20, 21, 22, parallèlement aux fontures et portées à leurs extrémités par deux montants 23 et 24. Sur chacune de ces barres 17 à 22 est monté coulissant un guide-fil 25, respectivement, 26, 27, 28, 29, 30. Sur chaque guide-fil est monté un bec-fil tel que 31. Chaque guide-fil est entraîné le long de sa barre au moyen d'un petit moteur électrique individuel par l'intermédiaire d'une courroie ou d'une vis sans fin (non représentée). La suppression du chariot libère tout l'espace au-dessus des fontures, ce qui permet de disposer librement les barres des guide-fil à la hauteur et avec l'écartement qui convient le mieux à la saisie et à l'entraînement des fils. Il est en outre sans autre possible d'augmenter le nombre des barres, c'est-à-dire de guide-fil et par conséquent le nombre de fils différents susceptibles d'être tricotés.Above the beds 2 and 3 extend a number of bars, in the example shown six bars 17, 18, 19, 20, 21, 22, parallel to the beds and carried at their ends by two uprights 23 and 24 On each of these bars 17 to 22 is slidably mounted a thread guide 25, respectively, 26, 27, 28, 29, 30. On each thread guide is mounted a thread spout such as 31. Each thread guide is driven along its bar by means of a small individual electric motor via a belt or a worm (not shown). The removal of the cart frees up all the space above the beds, which allows freely arrange the bars of the wire guides at the height and with the spacing which is most suitable for gripping and driving the wires. It is furthermore without other possibility to increase the number of bars, that is to say of thread guide and consequently the number of different threads capable of being knitted.

En arrière des fontures on trouve, de manière connue, un support de bobines 31 sur lequel sont montés six bobines tels que la bobine 32. Les bobines n'ont pas été représentées à la figure 1. En face de chacune des bobines et au-dessus de chaque guide-fil correspondant sont montés des renvois de fils 33, 34, 35, 36, 37, 38.Behind the needle beds there is, in a known manner, a bobbin support 31 on which are mounted six bobbins such as the bobbin 32. The bobbins have not been shown in FIG. 1. Opposite each of the bobbins and au- above each corresponding wire guide are mounted wire references 33, 34, 35, 36, 37, 38.

Les moteurs 12 et 15, ainsi que les moteurs des guide-fils sont commandés par une unité logique de traitement programmable à micro-processeur. Chaque moteur est commandé individuellement. Cela signifie que les porte-cames 4 et 5 peuvent être momentanément désynchronisés pour être décalés l'un par rapport à l'autre.The motors 12 and 15, as well as the motors of the wire guides are controlled by a programmable logic processing unit with microprocessor. Each motor is controlled individually. This means that the cam holders 4 and 5 can be momentarily desynchronized to be offset with respect to each other.

Le principal avantage de la machine à tricoter représenté découle immédiatement du dessin. On voit que les fils 39 à 44 vont vers chacun des guide-fil par le plus court chemin. Supposons que les porte-cames se déplacent dans le sens de la flèche. Les guide-fil 26 et 30 sont entraînés par leurs moteurs respectifs de manière synchronisée au déplacement des porte-cames et les fils 40 et 44 sont tricotés. La tension sur le fil 40 est minimale. Pour changer de fil, il suffit d'écarter le fil tricoté de la trajectoire des aiguilles et d'amener un autre fil dans cette trajectoire en déplaçant son guide-fil de manière adéquate, par exemple comme décrit dans la demande de brevet EP 0 415 512.The main advantage of the knitting machine shown is immediately apparent from the design. We see that the wires 39 to 44 go to each of the wire guides by the shortest path. Suppose that the cam carriers move in the direction of the arrow. The thread guides 26 and 30 are driven by their respective motors in synchronization with the movement of the cam holders and the threads 40 and 44 are knitted. The tension on the wire 40 is minimal. To change the thread, it suffices to move the knitted thread away from the path of the needles and to bring another thread in this path by moving its thread guide adequately, for example as described in patent application EP 0 415 512.

Il devient possible de travailler des fils plus fragiles que les fils actuels. Il est possible d'augmenter considérablement le nombre de barres et de guide-fil, par exemple de porter ce nombre à vingt, ce qui permet de tricoter en vingt couleurs différentes.It becomes possible to work with more fragile threads than current threads. It is possible to considerably increase the number of bars and thread guides, for example to increase this number to twenty, which allows knitting in twenty different colors.

La possibilité de décaler à volonté les porte-cames l'un par rapport à l'autre ouvre d'immenses possibilités de tricotage. Un faible décalage permet de resserrer ou au contraire d'agrandir des mailles. Un décalage plus grand devrait permettre de transformer une machine à simple chute en machine à double chute. Les possibilités ouvertes sont immenses.The possibility of shifting the cam holders at will relative to each other opens up immense knitting possibilities. A slight offset makes it possible to tighten or on the contrary to enlarge the meshes. A larger offset should make it possible to transform a single fall machine into a double fall machine. The possibilities are endless.

Selon une variante plus simple, les roues dentées 11 et 14 entraînant les courroies crantées pourraient être solidaires d'un arbre commun entraîné par un seul moteur. De même, les renvois 16, également dentés, pourraient être rigidement liés par un axe commun. Une telle exécution, avec des courroies crantées jumelles, permet d'assurer l'alignement des porte-cames comme c'est le cas sur un chariot traditionnel. La liaison rigide entre les roues dentées compense les écarts possibles dus à l'élasticité des courroies.According to a simpler variant, the toothed wheels 11 and 14 driving the toothed belts could be integral with a common shaft driven by a single motor. Similarly, the references 16, also toothed, could be rigidly linked by a common axis. Such an execution, with twin toothed belts, ensures the alignment of the cam holders as is the case on a traditional carriage. The rigid connection between the toothed wheels compensates for the possible deviations due to the elasticity of the belts.

Les porte-cames pourraient être entraînés par d'autres moyens, par exemple, au moyen d'une vis sans fin, qui pourrait remplacer l'une des barres de guidage.The cam holders could be driven by other means, for example, by means of an endless screw, which could replace one of the guide bars.

Chaque barre pourrait porter deux guide-fil, soit un guide-fil de chaque côté de la barre.Each bar could carry two thread guides, one thread guide on each side of the bar.

La technique décrite s'applique bien entendu aussi à une machine double.The technique described applies of course also to a double machine.
