Description

La présente invention est relative à des perfectionnements apportés aux mécanismes de commande du mouvement de va-et-vient des cadres de griffes d'une mécanique d'armure.The present invention relates to improvements made to back and forth movement control mechanisms for claw frames armor mechanics.

La présente Demanderesse à mis au point et utilisé vers 1975 un mécanisme de commande du mouvement de va-et-vient des cadres de griffes d'une mécanique d'armure à crochets tournants dénommé CR 520, constitué essentiellement par un jeu de deux cames complémentaires montées sur l'arbre de commande de la mécanique et qui coopèrent chacune avec un galet suiveur monté sur un levier basculeur pivotant librement autour d'un axe, ledit basculeur étant relié à chaque cadre de griffes par deux bielles complémentaires, respectivement longue et courte. Bien entendu, il existait un jeu de deux cames complémentaires de chaque côté du bâti de la machine. Les extrémités des bielles opposées à celles commandées par le levier basculeur double étaient articulées au centre des cadres de griffes qui étaient d'autre part guidés par des organes appropriés pour qu'ils se déplacent soit en parallèle, soit obliquement l'un par rapport à l'autre.The present Applicant developed and used around 1975 a mechanism control of the back and forth movement of the claw frames armor mechanism with rotating hooks called CR 520, consisting of essentially by a set of two complementary cams mounted on the mechanical control shaft and which each cooperate with a follower roller mounted on a rocking lever freely pivoting around an axis, said rocker being connected to each frame of claws by two complementary rods, respectively long and short. Of course, there was a set of two complementary cams on each side of the frame of the machine. The ends of the rods opposite to those ordered by the double rocker lever were articulated in the center of the frames of claws which were on the other hand guided by appropriate organs so that they move either in parallel or obliquely one by compared to each other.

Une telle construction comprenant un nombre important de pièces de guidage, entraíne un coût excessif, un mouvement imprécis des cadres, et un mauvais rendement mécanique global. De plus, elle ne s'applique que très difficilement à une mécanique de grandes dimensions.Such a construction comprising a large number of guide parts, causes excessive cost, imprecise movement of frames, and poor overall mechanical performance. In addition, it only applies very hardly a mechanics of large dimensions.

Les perfectionnements qui font l'objet de la présente invention visent à permettre la réalisation d'un mécanisme de commande du genre en question, qui soit applicable à des cadres de griffes de grandes dimensions et dont le guidage soit réduit au strict minimum.The improvements which are the subject of the present invention aim to allow the realization of a control mechanism of the kind in question, which is applicable to large claw frames and whose guidance is reduced to the strict minimum.

A cet effet, le mécanisme de commande suivant l'invention est caractérisé en ce que l'arbre porte-cames est pourvu de chaque côté du bâti d'un second jeu de deux cames complémentaires décalé angulairement de 180° par rapport au premier coopérant chacune avec un galet suiveur monté sur un second basculeur double placé côte à côte avec le premier et qui est relié à chaque cadre de griffes au moyen de deux bielles respectivement longue et courte, de telle manière qu'un cadre de griffes soit entraíné par les deux bielles courtes des basculeurs dont les deux bielles longues entraínent l'autre cadre de griffes. To this end, the control mechanism according to the invention is characterized in that the camshaft is provided on each side of the frame a second set of two complementary cams angularly offset by 180 ° with respect to the first cooperating each with a follower roller mounted on a second double rocker placed side by side with the first and which is connected to each claw frame by means of two connecting rods respectively long and short, so that a frame of claws either driven by the two short rockers of the rockers, both of which long connecting rods drive the other frame of claws.

Grâce à cette disposition, l'ensemble du mécanisme qui est situé tout à fait au bas du châssis de la mécanique d'armure peut être disposé dans un carter assurant son graissage par barbottage.Thanks to this arrangement, the entire mechanism which is located at made at the bottom of the frame of the armor mechanics can be arranged in a casing ensuring its lubrication by bubbling.

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 est une vue en élévation de la partie du mécanisme de commande suivant l'invention, situé d'un côté de son bâti.
  • Fig. 2 est une coupe schématique suivant II-II (fig. 1) montrant l'agencement des cames complémentaires de part et d'autre du bâti de la machine comportant application de l'invention.
  • Fig. 3 est une vue semblable à celle de fig. 1 mais illustrant une variante.
    • 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 is an elevational view of the part of the control mechanism according to the invention, located on one side of its frame.
  • Fig. 2 is a diagrammatic section along II-II (FIG. 1) showing the arrangement of the complementary cams on either side of the frame of the machine comprising application of the invention.
  • Fig. 3 is a view similar to that of FIG. 1 but illustrating a variant.

    • On a représenté schématiquement en fig. 1 le bâti 1 d'une mécanique d'armure comprenant deux cadres de griffes 2, 3 se déplaçant en va-et-vient verticalement grâce à un mécanisme suivant l'invention. Ce mécanisme comprend deux ensembles identiques situés de chaque côté du bâti 1, comme illustré en fig. 2.There is shown schematically in FIG. 1 the frame 1 of a mechanical of armor comprising two claw frames 2, 3 moving back and forth vertically thanks to a mechanism according to the invention. This mechanism includes two identical sets located on each side of the frame 1, as illustrated in fig. 2.

    A la base du bâti 1, il est prévu un axe de commande transversal 4 entraíné en rotation à la manière usuelle à partir du métier à tisser auquel est associée la mécanique représentée. L'axe 4 comporte à chacune de ses extrémités dépassant hors du bâti un embout quadrangulaire 4a sur lequel sont calés deux groupes 5, 6 de deux cames complémentaires. Le premier groupe 5 situé le plus à l'extérieur comporte deux cames complémentaires placées côte à côte 50 et 51. Le second groupe 6, placé plus à l'intérieur sur l'embout 4a, est composé de deux cames complémentaires 60, 61.At the base of the frame 1, there is provided a transverse control axis 4 rotated in the usual way from the weaving loom with which the mechanics shown is associated. The axis 4 has at each of its ends projecting out of the frame a quadrangular endpiece 4 a on which are wedged two groups 5, 6 of two complementary cams. The first group 5 located furthest to the outside has two complementary cams placed side by side 50 and 51. The second group 6, placed further inside on the nozzle 4 a , is composed of two complementary cams 60, 61 .

    On retrouve la même structure de l'autre côté du bâti, symétriquement par rapport à son axe longitudinal. Bien entendu et pour des raisons qu'on expliquera mieux plus loin, les deux groupes de cames 5 et 6 sont décalés de 180°. We find the same structure on the other side of the frame, symmetrically with respect to its longitudinal axis. Of course and for reasons which will be explained better below, the two groups of cams 5 and 6 are offset by 180 °.

    La périphérie, de profil approprié, de la came 50 coopère avec un galet suiveur 7 solidaire d'un basculeur à deux bras 8, tandis que la périphérie de la came 51 est en contact avec un galet suiveur 9, également solidaire du basculeur 8. Ce dernier est monté à basculement autour d'un arbre transversal 10.The periphery, of suitable profile, of the cam 50 cooperates with a roller follower 7 secured to a two-arm rocker 8, while the periphery of cam 51 is in contact with a follower roller 9, also integral with the rocker 8. The latter is pivotally mounted around a transverse shaft 10.

    On retrouve la même disposition en ce qui concerne le groupe de cames 6. La périphérie de la came 61 est en appui permanent contre un galet suiveur 11, monté sur un second basculeur 12 basculant autour de l'arbre 10 à proximité immédiate du premier basculeur 8. La seconde came 61 coopère avec un second galet suiveur 13 également monté sur le basculeur 12.The same arrangement is found with regard to cam group 6. The periphery of the cam 61 is in permanent abutment against a follower roller 11, mounted on a second rocker 12 rocking around the shaft 10 in the immediate vicinity of the first rocker 8. The second cam 61 cooperates with a second follower roller 13 also mounted on the rocker 12.

    Dans ces conditions, lorsque l'arbre 4 tourne en entraínant en rotation les quatre cames 50, 51, 60 et 61, on provoque à la manière connue le pivotement alternatif des basculeurs 8 et 12 autour de leur axe 10. Il suffit alors de réunir les basculeurs aux deux cadres de griffes 2 et 3 pour faire déplacer ceux-ci de manière alternative dans le sens vertical. A cet effet, l'une des branches du basculeur 8, par exemple celle de gauche en fig. 1, est associée à pivotement à un levier court 14 dont l'autre extrémité est articulée au cadre de griffes inférieur 3. Au second bras du basculeur 8 (celui de droite en fig. 1) est articulée la première extrémité d'un levier 15 dont l'autre extrémité est articulée au cadre de griffes supérieur 2.Under these conditions, when the shaft 4 rotates causing it to rotate the four cams 50, 51, 60 and 61, in the known manner, the alternating pivoting of rockers 8 and 12 around their axis 10. It then simply join the rockers to the two claw frames 2 and 3 to move these alternately vertically. For this purpose, one of the branches of the rocker 8, for example that on the left in fig. 1, is associated with pivoting with a short lever 14 of which the other end is articulated to the lower claw frame 3. Au second arm of the rocker 8 (the one on the right in fig. 1) is articulated first end of a lever 15 whose other end is articulated to the upper claw frame 2.

    Le second basculeur 12 est quant à lui articulé par son premier bras à une bielle 16 disposée à côté de la bielle 14 et articulée également au cadre de griffes supérieur 2. Le second bras du basculeur 12 est associé au cadre inférieur 3 par l'intermédiaire d'une bielle 17.The second rocker 12 is articulated by its first arm to a connecting rod 16 disposed next to the connecting rod 14 and also articulated at upper claw frame 2. The second arm of the rocker 12 is associated to the lower frame 3 by means of a connecting rod 17.

    On observera que les bielles 14 et 17 sont courtes et de même longueur, tandis que les bielles 15 et 16 sont longues en étant également de même longueur. Ainsi, lors du mouvement d'oscillation des basculeurs 8 et 12 par l'intermédiaire des cames, on provoque le déplacement alternatif vertical en sens contraires des cadres de griffes 2 et 3.We will observe that the connecting rods 14 and 17 are short and of the same length, while the connecting rods 15 and 16 are long while also being the same length. Thus, during the rocking movement of rockers 8 and 12 by means of the cams, the reciprocating movement is caused vertical in opposite directions of claw frames 2 and 3.

    On observe que les deux bras des deux basculeurs comportent des lumières courbes 80, 81 respectivement 120, 121 dans lesquelles les extrémités inférieures des quatre bielles précitées sont montées à pivotement. Il est évident qu'en changeant la position des extrémités inférieures des quatre bielles par rapport aux lumières des basculeurs, on provoque soit la variation de course des deux cadres 2 et 3, soit encore leur obliquité.It is observed that the two arms of the two rockers have lights curves 80, 81 respectively 120, 121 in which the ends lower of the four aforementioned connecting rods are pivotally mounted. he is obvious that by changing the position of the lower ends of the four connecting rods relative to the lights of the rockers, we cause either the variation in travel of the two frames 2 and 3, that is to say their obliquity.

    Pour des raisons techniques facilitant la construction, les axes géométriques des axes 4 et 10 peuvent être décalés latéralement d'une valeur d, mais il va de soi que sans sortir du cadre de l'invention, les deux axes géométriques considérés pourraient être situés dans un même plan vertical.For technical reasons facilitating construction, the geometric axes of axes 4 and 10 can be offset laterally by a value d , but it goes without saying that without departing from the scope of the invention, the two geometric axes considered could be located in the same vertical plane.

    En fig. 2, on a indiqué les repères des composants symétriques de ceux précédemment décrits avec les mêmes références affectées d'un accent.In fig. 2, the marks of the symmetrical components of those have been indicated previously described with the same references assigned an accent.

    En particulier il est possible de placer, comme illusré en fig. 3, l'ensemble du mécanisme en haut du châssis. Dans ces conditions ce sont les bielles courtes 14, 17 qui relient les basculeurs 8, 12 au cadre de griffes supérieur 2 tandis que les bielles longues 15, 16 relient lesdits basculeurs 8, 12 au cadre de griffes inférieur 3.In particular it is possible to place, as illustrated in fig. 3, the whole of the mechanism at the top of the chassis. Under these conditions it is the short connecting rods 14, 17 which connect the rockers 8, 12 to the frame of upper claws 2 while the long connecting rods 15, 16 connect the said rockers 8, 12 at the lower claw frame 3.
