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 armor of the rotary type for crowd formation 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.We know that in their classic structure, the tack mechanics include a number of oscillating actuators which are pivotally mounted on a common fixed axis and which are connected to the usual healds of the weaving machine by a pulling system incorporating return levers and transmission rods, which levers pivot themselves on fixed axes carried by the supporting frame the usual housing of the mechanics considered.

Dans la Demande de Brevet EP-A-0 740 003, qui représente le seul état de la technique pertinent et qui relève de l'Article 54(3) CBE, 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 EP-A-0 740 003, which represents the only relevant prior art and which falls under Article 54 (3) EPC, we have described a support frame for armor mechanics comprising a U-shaped cross-section piece open towards the high, the longitudinal wings of which are arranged to support the pivot axes of the levers of the pulling system which ensures the vertical control of the heald frames of the weaving machine. In the embodiment described and illustrated in this Request for Patent, 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, by means of an arrangement suitable, such a support frame can advantageously take the place of the casing usual armor mechanics.

La mécanique d'armure du type rotatif suivant L'invention est définie à la revendication 1.The armor mechanics of the rotary type according to the invention is defined at 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'entraínement 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 making one of the ends of the U-shaped part which forms the support frame two raised side cheeks which are drilled to support the drive shaft and the common pivot axis of the oscillating actuators mechanics, and to seal this part tightly so that it can contain the usual oil bath intended for lubrication moving parts of the mechanics and the associated draft system to it, 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 part is advantageously closed towards the top by a cover which avoids the fallout of textile stuffing in the oil bath, which cover is cut out with suitable lights for the passage of vertical connecting rods intended for maneuvering heald frames. It is against this cover that are fixed The ramps for the flow of oil on the various points of articulation deflection levers and oscillating actuators of mechanics, which organs can thus have forms simple 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 attached drawing, given as an example, will allow a better understanding the invention, the characteristics it presents and the advantages that it is likely to provide:

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 armor mechanics 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 mechanical lubrication system in the case of a dobby rotary type eccentric and connecting rods.

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

Fig. 5 illustre l'application de l'invention à une mécanique rotative à cames.Fig. 5 illustrates the application of the invention to rotary mechanics with cams.

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, Reference 1 designates the part which simultaneously constitutes the support frame and the armor housing. This part 1 has a U-shaped cross section open towards the top, which is defined by a flat bottom 2, two longitudinal wings 3 and two transverse partitions with 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'entraínement 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 one to the other by a horizontal rod 19, one of said levers being in 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 are completed by a cover 21 which covers the part of the part 1 arranged below the frames 18 and which is cut out of two transverse lights 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, actuating rods 12 and the reading device 23 which operates the programmed control of said connecting 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. We thus obtain a very robust construction set which is can be mounted in the lower part of the weaving machine to which it is intended to be associated. Once the set is in place instead, just 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 well the mounting of a rotary dobby according to the invention whose support frame is securely attached to the two vertical structures 24 of a conventional weaving machine. This dobby is equipped with a lubrication system which includes a pump 25 for feeding a series of transverse lubrication ramps 26 arranged above the pivot axes 15 of the deflection levers 16, above of the axis 13 on which the oscillating members 14 pivot, above of the shaft 11 and above the connecting points of the connecting rods 19 and 20 and links 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.The fact that the oil from the corresponding ramp 26 flows freely and that the bottom 2 of the part 1 is provided flat, we can adopt a bottom pulling system, each member 14 extending downward to from an upper hub engaged on axis 13, this simple profile facilitates adjusting the coupling point of each of the oblique connecting rods 20 on these members 14 for adjusting the crowd after removing the cover upper 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 to the fig. 4 which shows the complex profile of the oscillating members 14 'of a classic mechanical from below, being further observed that the pivot axis 13 'of these members 14' cannot be lubricated effectively the fact that it is placed outside the usual mechanical housing. The straight profile of the members 14 ensures rigidity and resistance much higher than those of 14 'organs. Note that the system drawing from below according to fig. 3 reduces the size of the assembly in the vertical direction as in the horizontal direction; in addition, the movement diagrams obtained prove to be advantageous for certain weaving conditions (for example low crosses).

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 armor mechanics at cams like the one illustrated in fig. 5, in which the command oscillating members 14 coupled to the oblique connecting rods 20 is operated at using additional cams 27 which are wedged on the motor shaft 11 to act on rollers 28 carried by said members 14.
