Description

On sait que dans les mécaniques du genre Verdol le papier est palpé par une série d'aiguillettes dont la position verticale de chacune d'elles varie suivant que son extrémité inférieure bute contre le papier ou pénètre dans un trou ménagé dans celui-ci. Chaque aiguillette est associée à un butoir dont la position varie en fonction de celle de l'aiguillette correspondante. C'est ainsi que si le butoir se trouve en regard d'un des éléments de poussée du train de barres, l'avance de celui-ci provoque la translation du butoir et celle de l'aiguille correspondante en vue de presser le crochet associé à cette aiguille. Au contraire s'il y a un.trou l'aiguillette descend davantage si bien que le butoir échappe à l'action du train de barres.We know that in mechanics of the Verdol type, the paper is palpated by a series of needles, the vertical position of each of which varies depending on whether its lower end abuts against the paper or enters a hole in it. Each needle is associated with a stopper whose position varies as a function of that of the corresponding needle. Thus, if the stopper is located opposite one of the pushing elements of the train of bars, the advance of the latter causes the translation of the stopper and that of the corresponding needle in order to press the associated hook to this needle. On the contrary, if there is a hole, the needle descends more so that the stop escapes the action of the train of bars.

Si l'on veut inverser l'information lue, c'est-à-dire effectuer la translation du butoir lorsqu'un trou se trouve sous l'aiguillette considérée, il suffit de déplacer l'ensemble des éléments du train de barres ; ainsi le butoir qui était en regard d'un des éléments de poussée ne l'est plus et celui qui ne l'était pas s'y trouve. Bien entendu le papier reste en place sous les aiguillettes tant que les butoirs doivent être sollicités dans le sens de leur translation par le train de barres.If you want to reverse the information read, that is to say translate the stop when a hole is under the needle considered, simply move all the elements of the train of bars; thus the stopper which was opposite one of the thrust elements no longer is and that which was not there is there. Of course the paper remains in place under the needles as long as the stops must be biased in the direction of their translation by the train of bars.

On comprend aisément que le déplacement de celui-ci entraîne la réalisation de mécanismes compliqués qui grèvent le prix de revient d'une'mécanique ainsi agencée.It is easily understood that the displacement of the latter entails the production of complicated mechanisms which increase the cost price of a mechanical arrangement thus arranged.

Les perfectionnements qui font l'objet de la présente invention visent à remédier à cet inconvénient et à supprimer le déplacement vertical des éléments de poussée du train de barres tout en limitant au minimum le temps de présence du papier sous les aiguillettes.The improvements which are the subject of the present invention aim to remedy this drawback and to eliminate the vertical displacement of the pushing elements of the train of bars while minimizing the time of presence of the paper under the needles.

Conformément à l'invention ce ne sont plus les éléments de poussée du train de barres qui sont déplacés mais les aiguillettes. Pour ce faire chacune d'elles comporte des moyens d'être associée à une plaque déplaçable qui constitue une espèce de mémoire de la sélection opérée. En effetà chaque lecture la plaque en question est déplacée pour venir coopérer avec un organe.de retenue des aiguillettes de telle sorte qu'on peut alors conserver la sélection même en désaccouplant ces dernières et le papier. De cette manière on prévoit de déplacer verticalement l'ensemble du système de support et d'avance du papier de telle sorte qu'il puisse avancer pendant le déplacement du train de barres. On obtient ainsi un gain de temps appréciable et une diminution du temps de pression des aiguillettes sur le papier de sorte que celui-ci étant moins sollicité présente une longévité plus importante.In accordance with the invention, it is no longer the pushing elements of the train of bars which are displaced but the points lettes. To do this, each of them has means of being associated with a movable plate which constitutes a kind of memory of the selection made. In fact, at each reading, the plate in question is moved to cooperate with a device for retaining the needles so that the selection can then be preserved even by uncoupling the latter and the paper. In this way provision is made to vertically move the entire support and paper advance system so that it can advance during the movement of the train of bars. An appreciable saving of time is thus obtained and a reduction in the pressure time of the needles on the paper so that the latter being less stressed has a greater longevity.

Le dessin annexé, donné à titre d'exemple permettra de mieux comprendre l'invention, les caractéristiques qu'elle présente et les avantages qu'elle est susceptible de procurer :

  • Fig. 1 représente schématiquement une mécanique d'armure Verdol comportant application des perfectionnements suivant l'invention.
  • Fig. 2 à 8 illustrent le fonctionnement du dispositif de lecture établi conformément à l'invention.
  • Fig. 9 à 12 sont des vues semblables respectivement à fig. 2, 4, 5 et 8 mais relatives à une variante de réalisation de l'invention.
The appended drawing, given by way of example, will allow a better understanding of the invention, the characteristics which it presents and the advantages which it is capable of providing:
  • Fig. 1 schematically represents a Verdol armor mechanism comprising application of the improvements according to the invention.
  • Fig. 2 to 8 illustrate the operation of the reading device established in accordance with the invention.
  • Fig. 9 to 12 are views similar respectively to FIG. 2, 4, 5 and 8 but relating to an alternative embodiment of the invention.

On a représenté en fig. 1 le principe d'une mécanique Verdol comprenant à la manière connue une série d'aiguillettes 1 dont l'extrémité inférieure vient palper un papier 2`comportant des perforations 2a et qui est supporté par un mécanisme d'entraînement 3. Chaque aiguillette est pourvue d'un oeillet la dans lequel passe un butoir horizontal 4 déplaçable axialement au moyen d'un des éléments de poussée 5a d'un train de barres 5 de manière à communiquer ce mouvement à une aiguille 6 à l'encontre de la réaction d'un ressort de compression 7. L'aigpille 6 étant associée à un crochet 8, si le train de barres 5 se déplace vers la droite le crochet 8 est déformé par exemple pour que son bec supérieur 8a échappe à une griffe 9a d'un cadre 9. Le bas du crochet est associé à une lisse 10 destinée à lever un fil de chaîne 11 disposé sur un métier à tisser.There is shown in fig. 1 the principle of Verdol mechanics comprising in the known manner a series of needles 1 whose lower end palpates a paper 2` having perforations 2a and which is supported by a drive mechanism 3. Each needle is provided an eyelet la through which passes a horizontal stop 4 movable axially by means of one of the pushing elements 5a of a train of bars 5 so as to communicate this movement to a needle 6 against the reaction of a spring of 7. The compression knitting needles p ille 6 being associated with a hook 8, if the bar rail 5 moves to the right the hook 8 is deformed such that its upper beak 8a escapes claw 9a of a frame 9 The bottom of the hook is associated with a heddle 10 intended to lift a warp thread 11 placed on a weaving loom.

En fonctionnement l'ensemble des aiguillettes 1 est appliqué contre le papier 2 qui se déplace de manière saccadée, synchronisée avec le déplacement des aiguillettes c'est-à-dire leur mouvement vertical. Lorsque le bas d'une aiguillette 1 bute contre le papier, le butoir 4 correspondant se trouve en face de l'élément 5a du train de barres 5 de sorte que si celui-ci est déplacé le butoir subit une translation vers la- droite.In operation, the set of needles 1 is applied against the paper 2 which moves in a jerky manner, synchronized with the movement of the needles, that is to say their vertical movement. When the bottom of a needle 1 abuts against the paper, the corresponding stopper 4 is located opposite the element 5a of the train of bars 5 so that if the latter is moved the stopper undergoes translation to the right.

Pour la fabrication de certains tissus et en particulier du tissu éponge le papier est perforé de manière rigoureusement inverse à deux positions successives. Conformément à l'invention on prévoit un dispositif susceptible de permettre l'inversion de la sélection sans avancer le papier.For the manufacture of certain fabrics and in particular terry cloth, the paper is perforated in a strictly reverse manner at two successive positions. According to the invention there is provided a device capable of permitting the inversion of the selection without advancing the paper.

A cet effet on prévoit de placer au-dessus du papier une plaque 12 comportant autant de perforations 12a que d'aiguillettes de manière que ces dernières traversent toutes lesdites perforations. Chaque aiguillette est pourvue de deux cambrages en U lb, lc de profondeur inférieure à la largeur de la perforation 12a et dont la hauteur de leur voile transversal orienté verticalement est supérieure à l'épaisseur de la plaque 12.To this end, provision is made to place a plate 12 having as many perforations 12a as needles above the paper so that the latter pass through all of said perforations. Each needle is provided with two camberings in U lb, lc of depth less than the width of the perforation 12a and the height of their transverse veil oriented vertically is greater than the thickness of the plate 12.

Lorsque les aiguillettes 1 butent contre le papier c'est leur cambrage inférieur lc qui se trouve au niveau de la plaque 12, tandis que si l'aiguillette pénètre dans la perforation 2a du papier c'est le cambrage supérieur lb qui se trouve en vis-à-vis de la plaque 12 (fig. 5).When the needles 1 abut against the paper it is their lower camber lc which is at the level of the plate 12, while if the needle enters the perforation 2a of the paper it is the upper camber lb which is located in screw opposite plate 12 (fig. 5).

Dans l'un ou l'autre cas dès que la sélection est terminée, c'est-à-dire une fois que les aiguillettes ont accompli leur descente dans les trous du papier ou viennent buter sur celui-ci, on déplace vers la gauche la plaque 12 de manière que l'un ou l'autre des cambrages vienne se verrouiller par rapport au bord de la perforation 12a correspondante (fig. 2 et 6). Dans la première figure l'aiguillette est en position haute puisque son extrémité inférieure bute contre le papier et par conséquent le butoir 4 se trouve en face de l'élément 5a du train de barres 5, si bien que lorsque celui-ci se déplace (fig. 3) l'aiguille 4 subit une translation. En fig. 5 l'aiguillette est en position basse et le butoir n'est pas actionné par l'élément 5a lors du déplacement du train de barres (fig. 7).In one or the other case as soon as the selection is complete, that is to say once the needles have completed their down into the holes in the paper or come up against it, the plate 12 is moved to the left so that one or the other of the bends comes to lock relative to the edge of the corresponding perforation 12a (fig. 2 and 6). In the first figure, the needle is in the high position since its lower end abuts against the paper and consequently the stopper 4 is located opposite the element 5a of the train of bars 5, so that when the latter moves ( Fig. 3) the needle 4 undergoes translation. In fig. 5 the needle is in the low position and the stopper is not actuated by the element 5a during the movement of the train of bars (fig. 7).

On comprend aisément que l'action de la plaque 12 mémorise . en quelque sorte la position des aiguillettes puisque celles qui butent contre le papier aussi bien que celles qui ont pénétré dans ses trous 2a sont verrouillées en position par la plaque 12. Dans ces conditions il est alors possible de faire subir au support 3 une descente dégageant les aiguillettes du papier et de ses trous et de faire avancer le papier pour l'amener à la position suivante (fig. 3 et 7).It is easy to understand that the action of the plate 12 memorizes. in a way the position of the needles since those which abut against the paper as well as those which have penetrated into its holes 2a are locked in position by the plate 12. Under these conditions it is then possible to subject the support 3 to a releasing descent the paper needles and its holes and advance the paper to bring it to the next position (figs. 3 and 7).

Si l'on désire inverser la sélection il suffit de déplacer la plaque 12 vers le haut (fig. 4 et 8) de telle façon que les butoirs qui étaient en vis-à-vis des éléments de poussée du train de barres 5 échappent à l'action de ceux-ci, ou qu'au contraire les butoirs non intéressés viennent se placer en vis-à-vis des éléments de poussée (fig. 8).If you wish to invert the selection, you just have to move the plate 12 upwards (fig. 4 and 8) in such a way that the buffers which were opposite the pushing elements of the train of bars 5 escape the action of these, or that on the contrary the bumpers not interested are placed opposite the pushing elements (fig. 8).

On pourrait obtenir un résultat identique en ce qui concerne l'inversion en.prévoyant que le support 3 comporte des alésages borgnes 3a sur le fond desquels les aiguillettes traversant les trous 2a viendraient buter (fig. 11). En fig. 9 on a représenté une aiguillette venant buter sur le papier 2. Dans les deux cas illustrés en fib. 9 et 11 il suffit de déplacer le support 3 vers le bas (fig. 10 et 12) pour obtenir l'inversion de 1. sélection sans avance du papier. Bien entendu avec le dispositif illustré en fig. 9 à 12 il n'est pas possible d'avancer le papier pendant le mouvement d'avance du train de barres 5 puisque les aiguilles restent en contact avec lui ou traversent ses trous 2a.An identical result could be obtained with regard to the inversion en.prévoyant that the support 3 has blind holes 3a on the bottom of which the needles passing through the holes 2a would abut (fig. 11). In fig. 9 there is shown a needle coming to abut on the paper 2. In the two cases illustrated in fib. 9 and 11 it suffices to move the support 3 down (fig. 10 and 12) to obtain the inversion of 1. selection without advance of the paper. Of course with the device illustrated in fig. 9 to 12 it is not possible to advance the paper during the advance movement of the train of bars 5 since the needles remain in contact with it or pass through its holes 2a.

On a ainsi réalisé un dispositif de lecture du papier perforé comportant des moyens simples d'inverser la sélection et qui peut comprendre avantageusement un système de mémorisation de cette dernière de manière à gagner du temps sur l'avance du papier.A device for reading the perforated paper has thus been produced comprising simple means for inverting the selection and which may advantageously include a system for storing the latter so as to save time on the advance of the paper.
