Description

La présente invention a trait aux ratières et autres mécaniques d'armure du type rotatif pour la formation de la foule sur les machines à tisser.The present invention relates to dobbies and other mechanical weaving of the rotary type for training the crowd on weaving machines.

On sait que dans leur structure classique, les mécaniques d'amure comprennent un certain nombre d'organes oscillants de manoeuvre qui sont montés pivotants sur un axe fixe commun et qui sont reliés aux cadres de lisses usuels de la machine à tisser par un système de tirage incorporant des leviers de renvoi et des bielles de transmission, lesquels leviers pivotent eux-mêmes sur des axes fixes portés par le bâti supportant le carter usuel de la mécanique considérée.It is known that in their conventional structure, the tack mechanics comprise a certain number of oscillating operating members which are pivotally mounted on a common fixed axis and which are connected to the usual heald frames of the weaving machine by a system of draft incorporating return levers and transmission rods, which levers pivot themselves on fixed axes carried by the frame supporting the usual housing of the mechanics considered.

Dans la Demande de Brevet N° 9505241 déposée le 26.04.1995 au nom de la Déposante, on a décrit un bâti-support pour mécanique d'armure comprenant une pièce à section transversale en forme de U ouverte vers le haut, dont les ailes longitudinales sont agencées pour supporter les axes de pivotement des leviers de renvoi du système de tirage qui assure la commande verticale des cadres de lisses de la machine à tisser. Dans la forme de réalisation décrite et illustrée dans cette Demande de Brevet, la mécanique est fixée contre un caisson rapporté à l'une des extrémités de ce bâti-support.In Patent Application N ° 9505241 filed on 04.26.1995 in the name of the Applicant, a support frame for armor mechanics has been described comprising a U-shaped cross-section piece open upwards, the longitudinal wings of which are arranged to support the pivot axes of the levers of the drawing system which provides vertical control of the heald frames of the weaving machine. In the embodiment described and illustrated in this Patent Application, the mechanics are fixed against a box attached to one of the ends of this support frame.

La présente invention se fonde sur le fait que, moyennant un agencement approprié, un tel bâti-support peut avec avantage tenir lieu du carter usuel des mécaniques d'armure.The present invention is based on the fact that, with an appropriate arrangement, such a support frame can advantageously take the place of the usual casing of armor mechanics.

La mécanique d'armure du type rotatif suivant l'invention est définie à la revendication 1.The rotary type armor mechanics according to the invention is defined in claim 1.

En fait l'invention consiste essentiellement à faire comporter à l'une des extrémités de la pièce à section en U qui forme le bâti-support deux joues latérales surélevées qui sont percées pour supporter l'arbre d'entraînement et l'axe commun de pivotement des organes oscillants de manoeuvre de la mécanique, et à fermer de manière étanche cette pièce afin qu'elle puisse renfermer le bain d'huile usuel destiné à la lubrification des éléments mobiles de la mécanique et du système de tirage associé à celle-ci, et ce au moyen d'un système de graissage incorporé.In fact, the invention essentially consists in having at one end of the U-shaped part which forms the support frame two raised lateral cheeks which are drilled to support the drive shaft and the common axis of pivoting of the oscillating mechanical operating members, and of sealing this part in a sealed manner so that it can contain the usual oil bath intended for the lubrication of the mobile elements of the mechanics and of the pulling system associated with the latter , and this by means of an incorporated lubrication system.

On conçoit que la pièce à section en U est avantageusement fermée vers le haut par un couvercle qui évite les retombées des bourres textiles dans le bain d'huile, lequel couvercle est découpé de lumières appropriées pour le passage des bielles verticales destinées à la manoeuvre des cadres de lisses. C'est contre ce couvercle que viennent se fixer les rampes pour l'écoulement de l'huile sur les différents points d'articulation des leviers de renvoi et des organes oscillants de manoeuvre de la mécanique, lesquels organes peuvent ainsi présenter des formes simples qui facilitent, par suite notamment de leur accessibilité améliorée, les opérations destinées au réglage de la foule.It is understood that the U-shaped piece is advantageously closed upwards by a cover which prevents the fallout of the textile flocks in the oil bath, which cover is cut out of apertures suitable for the passage of vertical connecting rods intended for the operation of heald frames. It is against this cover that the ramps are fixed for the flow of oil on the various points of articulation of the return levers and of the oscillating mechanical operating members, which members can thus have simple shapes which facilitate, in particular as a result of their improved accessibility, the operations intended for adjusting the crowd.

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 :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 est une vue en perspective illustrant l'agencement général d'une mécanique d'armure suivant l'invention.Fig. 1 is a perspective view illustrating the general arrangement of an armor mechanism according to the invention.

Fig. 2 est une coupe longitudinale de la mécanique suivant fig. 1, après montage des éléments supposés démontés en fig. 1.Fig. 2 is a longitudinal section of the mechanics according to FIG. 1, after assembly of the elements assumed to be dismantled in fig. 1.

Fig. 3 est une coupe longitudinale exposant de manière plus précise le système de lubrification de la mécanique dans le cas d'une ratière rotative du type à bielles et excentriques.Fig. 3 is a longitudinal section exposing more precisely the lubrication system of the mechanics in the case of a rotary dobby of the connecting rod and eccentric type.

Fig. 4 rappelle l'agencement des mécaniques usuelles à tirage par dessous.Fig. 4 recalls the arrangement of the usual mechanical draws from below.

Fig. 5 illustre l'application de l'invention à une mécanique rotative à cames.Fig. 5 illustrates the application of the invention to a rotary cam mechanism.

En fig. 1 et 2, la référence 1 désigne la pièce qui constitue simultanément le bâti-support et le carter de la mécanique d'armure. Cette pièce 1 présente en section transversale un profil en U ouvert vers le haut, qui est défini par un fond plat 2, deux ailes longitudinales 3 et deux cloisons transversales d'extrémités 4, étant observé que ces dernières assurent une fermeture parfaitement étanche afin que ladite pièce 1 ainsi agencée puisse renfermer sans fuite une quantité d'huile, référencée 5 en fig. 2.In fig. 1 and 2, the reference 1 designates the part which simultaneously constitutes the support frame and the casing of the armor mechanism. This part 1 has in cross section a U-shaped profile open upwards, which is defined by a flat bottom 2, two longitudinal wings 3 and two transverse partitions at the ends 4, it being observed that the latter ensure a perfectly sealed closure so that said part 1 thus arranged can contain without leaking a quantity of oil, referenced 5 in FIG. 2.

A l'une des extrémités de cette pièce 1, les deux ailes 3 présentent deux joues latérales surélevées 6. Si dans le mode d'exécution illustré, ces joues 6 sont directement solidaires des ailes 3, on peut très bien les constituer par deux platines rapportées par soudure ou par boulonnage sur lesdites ailes. Dans les ailes 3 et dans les joues 6 sont ménagées quatre paires d'ouvertures respectivement référencées 7, 8, 9 et 10, étant observé que les deux ouvertures de chaque paire sont alignées transversalement sur l'une et l'autre aile ou joue.

  • La paire d'ouvertures 7 accueille les roulements (non représentés) qui assurent le montage de l'arbre moteur 11 destiné à l'entraînement des bielles d'actionnement 12 d'une ratière rotative ;
  • La paire d'ouvertures 8 reçoit les extrémités de l'axe fixe 13 sur lequel pivote l'ensemble des organes oscillants de manoeuvre 14 ;
  • Dans chacune des paires d'ouvertures 9 et 10 viennent se loger les extrémités d'un axe fixe 15 formant pivot commun pour un ensemble de leviers de renvoi 16 reliés par des biellettes verticales 17 aux cadres de lisses 18 de la machine à tisser.
At one end of this part 1, the two wings 3 have two raised lateral cheeks 6. If in the illustrated embodiment, these cheeks 6 are directly integral with the wings 3, they can very well be constituted by two plates reported by welding or bolting on said wings. In the wings 3 and in the cheeks 6 are formed four pairs of openings respectively referenced 7, 8, 9 and 10, it being observed that the two openings of each pair are aligned transversely on one and the other wing or cheek.
  • The pair of openings 7 receives the bearings (not shown) which ensure the mounting of the motor shaft 11 intended for driving the actuating rods 12 of a rotary dobby;
  • The pair of openings 8 receives the ends of the fixed axis 13 on which the assembly of the oscillating operating members 14 pivots;
  • In each of the pairs of openings 9 and 10 are housed the ends of a fixed axis 15 forming a common pivot for a set of return levers 16 connected by vertical links 17 to the heald frames 18 of the weaving machine.

Les deux leviers 16 associés à un même cadre 18 sont attelés l'un à l'autre par une bielle horizontale 19, l'un desdits leviers étant en outre attelé par une bielle oblique 20 à l'un des organes oscillants 14, de façon à ce que le déplacement angulaire alternatif de cet organe assure le déplacement vertical du cadre 18 auquel il est attelé.The two levers 16 associated with the same frame 18 are coupled to each other by a horizontal rod 19, one of said levers being further coupled by an oblique rod 20 to one of the oscillating members 14, so that the alternating angular displacement of this member ensures the vertical displacement of the frame 18 to which it is coupled.

La mécanique suivant l'invention est complétée par un couvercle 21 qui recouvre la partie de la pièce 1 disposée au-dessous des cadres 18 et qui est découpé de deux lumières transversales pour le passage des deux séries de biellettes verticales 17. Ce couvercle 21 est prolongé par un capot amovible 22 qui assure la protection des organes oscillants 14, des bielles d'actionnement 12 et du dispositif de lisage 23 qui opère la commande programmée desdites bielles 12.The mechanics according to the invention is supplemented by a cover 21 which covers the part of the part 1 arranged below the frames 18 and which is cut out from two transverse openings for the passage of the two series of vertical rods 17. This cover 21 is extended by a removable cover 22 which protects the oscillating members 14, the actuating rods 12 and the reading device 23 which operates the programmed control of said rods 12.

On obtient de la sorte un ensemble de construction très robuste qui est susceptible d'être monté dans la partie inférieure de la machine à tisser à laquelle il est destiné à être associé. Une fois l'ensemble mis en place, il suffit de relier les biellettes 17 aux cadres de lisses 18.In this way, a very robust construction assembly is obtained which can be mounted in the lower part of the weaving machine with which it is intended to be associated. Once the assembly is in place, it suffices to connect the rods 17 to the heald frames 18.

Fig. 3 illustre bien le montage d'une ratière rotative suivant l'invention dont le bâti-support est solidement amarré aux deux structures verticales usuelles 24 d'une machine à tisser classique. Cette ratière est équipée d'un système de graissage qui comprend une pompe 25 pour l'alimentation d'une série de rampes transversales de lubrification 26 disposées au-dessus des axes de pivotement 15 des leviers de renvoi 16, au-dessus de l'axe 13 sur lequel pivotent les organes oscillants 14, au--dessus de l'arbre 11 et au-dessus des points d'attelage des bielles 19 et 20 et des biellettes 17.Fig. 3 illustrates the mounting of a rotary dobby according to the invention, the support frame of which is securely moored to the two usual vertical structures 24 of a conventional weaving machine. This dobby is equipped with a lubrication system which comprises a pump 25 for feeding a series of transverse lubrication ramps 26 disposed above the pivot axes 15 of the return levers 16, above the axis 13 on which the oscillating members 14 pivot, above the shaft 11 and above the coupling points of the connecting rods 19 and 20 and of the connecting rods 17.

Du fait que l'huile issue de la rampe 26 correspondante s'écoule librement et que le fond 2 de la pièce 1 est prévu plat, on peut adopter un système de tirage par le bas, chaque organe 14 s'étendant vers le bas à partir d'un moyeu supérieur engagé sur l'axe 13, ce profil simple facilite le réglage du point d'attelage de chacune des bielles obliques 20 sur ces organes 14 pour le réglage de la foule après démontage du capot supérieur de recouvrement 21-22.Because the oil from the corresponding ramp 26 flows freely and that the bottom 2 of the part 1 is provided flat, a drawing system can be adopted from below, each member 14 extending downwards at from an upper hub engaged on the axis 13, this simple profile makes it easier to adjust the coupling point of each of the oblique connecting rods 20 on these members 14 for adjusting the shed after dismantling the upper covering cover 21-22 .

Il suffit d'ailleurs de comparer la partie de gauche de fig. 3 à la fig. 4 qui montre le profil complexe des organes oscillants 14' d'une mécanique classique à tirage par dessous, étant en outre observé que l'axe de pivotement 13' de ces organes 14' ne peut être lubrifié efficacement du fait qu'il se trouve placé en dehors du carter usuel de la mécanique. Le profil droit des organes 14 assure une rigidité et une résistance bien supérieures à celles des organes 14' . On notera que le système de tirage par le bas suivant fig. 3 permet de diminuer l'encombrement de l'ensemble dans le sens vertical comme dans le sens horizontal ; de plus, les diagrammes de mouvements obtenus se révèlent avantageux pour certaines conditions de tissage (par exemple croisures basses).It suffices to compare the left part of fig. 3 in fig. 4 which shows the complex profile of the oscillating members 14 'of a conventional mechanical from below, being further observed that the pivot axis 13' of these members 14 'cannot be lubricated effectively because it is located placed outside the usual mechanical housing. The straight profile of the members 14 provides rigidity and resistance much greater than those of the members 14 '. Note that the bottom draw system according to fig. 3 reduces the size of the assembly in the vertical direction as in the horizontal direction; moreover, the movement diagrams obtained prove to be advantageous for certain weaving conditions (for example low crossings).

Il va de soi que l'invention est applicable aux mécaniques d'armure à cames du genre de celle illustrée en fig. 5, dans laquelle la commande des organes oscillants 14 attelés aux bielles obliques 20 est opérée à l'aide de cames complémentaires 27 qui sont calées sur l'arbre moteur 11 pour agir sur des galets 28 portés par lesdits organes 14.It goes without saying that the invention is applicable to cam armor mechanics of the kind of that illustrated in FIG. 5, in which the control of the oscillating members 14 coupled to the oblique connecting rods 20 is operated using complementary cams 27 which are wedged on the drive shaft 11 to act on rollers 28 carried by said members 14.
