Abstract

The frame comprises: (i) a single rectangular U-section member (8) which is open at the top and at both ends; and (ii) sides (9) carrying the pivots (18,19) of at least some of the return levers.

Description

La présente invention a trait aux ratières et autres mécaniques d'armure pour la formation de la foule sur les métiers à tisser, et elle concerne plus particulièrement les mécaniques de ce type à commande unique qui sont disposées latéralement en position basse par rapport au métier pour être reliées aux cadres de lisses usuels par un système de tirage comprenant, au-dessous desdits cadres, plusieurs séries de leviers de renvoi à profil substantiellement en équerre associés à des bielles de liaison sensiblement horizontales.The present invention relates to dobbies and other armor mechanics for training the crowd on weaving looms, and it relates more particularly to mechanics of this type with single control which are arranged laterally in the low position relative to the loom. be connected to the usual heald frames by a pulling system comprising, below said frames, several series of return levers with a substantially square profile associated with substantially horizontal connecting rods.

Dans la construction classique qu'on a illustrée aux fig. 1 et 2 du dessin annéxé aux présentes, la base du carter usuel 1 de la mécanique repose ordinairement sur deux fers 2 à section en C ouverts en vis-à-vis qui sont rendus solidaires des structures verticales 3 du métier à tisser à l'aide d'organes 4 en forme d'équerres. Sur l'aile supérieure de ces fers 2 sont rapportés, le plus souvent à l'aide de boulons, des oreilles 5 propres à former supports pour les axes de pivotement 6 des leviers de renvoi 7 du système de tirage qui assure la manoeuvre verticale des cadres de lisses CL.In the classical construction which has been illustrated in FIGS. 1 and 2 of the drawing appended to the present, the base of the usual casing 1 of mechanics usually rests on two irons 2 with C section open opposite which are made integral with the vertical structures 3 of the loom to the using 4 square-shaped organs. On the upper wing of these irons 2 are attached, most often using bolts, ears 5 suitable for forming supports for the pivot axes 6 of the return levers 7 of the pulling system which ensures the vertical maneuvering of the CL heald frames.

Cette construction classique n'est pas entièrement satisfaisante. La fixation des oreilles 5 constitue une opération qui grève sensiblement le prix de revient de l'ensemble. Par ailleurs, l'ensemble obtenu manque de rigidité et est le siège d'oscillations parasites qui perturbent le fonctionnement de la mécanique, tout particulièrement aux grandes vitesses de tissage maintenant imposées aux métiers à tisser.This conventional construction is not entirely satisfactory. The attachment of the ears 5 constitutes an operation which significantly strikes the cost price of the assembly. Furthermore, the assembly obtained lacks rigidity and is the site of parasitic oscillations which disturb the operation of the mechanics, especially at the high weaving speeds now imposed on the looms.

On notera au surplus que la lubrification des articulations des leviers de tirage 7 est délicate, cette opération occasionnant des chutes d'huile ou la formation de cambouis au-dessous du métier à tisser, zone particulièrement difficile à nettoyer.It will also be noted that the lubrication of the articulations of the pulling levers 7 is delicate, this operation causing drops of oil or the formation of sludge below the loom, an area which is particularly difficult to clean.

C'est à ces inconvénients qu'entend principalement remédier l'invention, laquelle a pour objet le bâti-support pour mécanique d'armure qui est défini à la revendication 1.It is these drawbacks that the invention mainly intends to remedy, which relates to the support frame for armor mechanics which is defined in claim 1.

En fait l'invention consiste à monter les axes d'articulation des leviers de renvoi sur les ailes latérales d'un bâti-support formé par une pièce unique à section transversale à profil en U qui est ouverte à ses extrémités et vers le haut.In fact, the invention consists in mounting the articulation axes of the deflection levers on the lateral wings of a support frame formed by a single piece with a U-shaped cross section which is open at its ends and upwards.

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 :

  • Comme on l'a indiqué plus haut, fig. 1 et 2 illustrent le mode de montage classique des ratières ou mécaniques usuel les.
  • Fig. 3 est une vue en perspective d'un bâti-support suivant l'invention, ce bâti-support étant équipé de la mécanique, mais étant représenté avant mise en place du système de tirage associé à celle-ci.
  • Fig. 4 illustre en perspective, préalablement à leur assemblage, les différentes pièces qui concourent à la réalisation du bâti-support suivant fig. 3.
  • Fig. 5 et 6 sont des coupes longitudinales schématiques montrant à plus grande échelle la fixation de chacune des deux extrémités du bâti-support aux structures verticales d'un métier à tisser.
  • Fig. 7 et 8 sont les coupes horizontales correspondantes.
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:
  • As indicated above, fig. 1 and 2 illustrate the conventional mounting mode of the usual dobby or mechanical.
  • Fig. 3 is a perspective view of a support frame according to the invention, this support frame being equipped with mechanics, but being shown before setting up the pulling system associated therewith.
  • Fig. 4 illustrates in perspective, prior to their assembly, the various parts which contribute to the production of the support frame according to FIG. 3.
  • Fig. 5 and 6 are schematic longitudinal sections showing on a larger scale the fixing of each of the two ends of the support frame to the vertical structures of a loom.
  • Fig. 7 and 8 are the corresponding horizontal sections.

Le bâti-support illustré en fig. 3 et 4 comprend une pièce principale 8 à section en U ouverte vers le haut, qui dans l'exemple de réalisation envisagé est formée par une tôle de forte épaisseur repliée deux fois à l'équerre pour définir deux ailes verticales 9 disposées de part et d'autre d'un fond 10.The support frame illustrated in fig. 3 and 4 comprises a main part 8 with a U-section open upwards, which in the envisaged exemplary embodiment is formed by a very thick sheet folded twice at right angles to define two vertical wings 9 arranged on the side and on the other side of a background 10.

Dans l'une des extrémités de la pièce 8 est engagé et fixé un robuste caisson 11 constitué par deux flasques verticaux 12 reliés par des traverses 13. L'assemblage du caisson 11 et de la pièce en U 8 est opéré à l'aide de brides verticales 9a solidaires des bords verticaux 9 de la pièce 8, et de contre-brides 14 rapportées dans des dépressions latérales 12a des flasques 12 du caisson 11.In one end of the part 8 is engaged and fixed a robust box 11 constituted by two vertical flanges 12 connected by crosspieces 13. The assembly of the box 11 and the U-shaped part 8 is carried out using vertical flanges 9 a secured to the vertical edges 9 of the part 8, and against flanges 14 attached in lateral depressions 12 to the flanges 12 of the box 11.

Le bâti-support 8-11 ainsi réalisé est destiné à être supporté et fixé à la base des structures verticales usuel les 3 du métier à tisser.The support frame 8-11 thus produced is intended to be supported and fixed to the base of the usual vertical structures 3 of the loom.

Pour l'extrémité du bâti-support qui est tournée du côté du caisson 11, la fixation est assurée à l'aide de brides 15 (fig. 4, 5 et 7) qui sont rendues solidaires des ailes 9 de la pièce 8 et sur lesquelles viennent se fixer des oreilles 16, elles-mêmes simultanément fixées aux flasques 12 du caisson 11 et à la structure 3. Deux brides supérieures 12b des flasques 12 sont boulonnées à la structure 3 afin de renforcer la rigidité de l'assemblage.For the end of the support frame which is turned towards the side of the box 11, the fixing is ensured by means of flanges 15 (fig. 4, 5 and 7) which are made integral with the wings 9 of the part 8 and on which are attached ears 16, themselves simultaneously fixed to the flanges 12 of the box 11 and to the structure 3. Two upper flanges 12 b of the flanges 12 are bolted to the structure 3 to strengthen the rigidity of the assembly.

L'extrémité opposée de la pièce 8 est équipée de deux brides verticales 9b (fig. 6 et 7) qui sont directement fixées à l'autre structure 3, cette solidarisation étant complétée par une entretoise 9c fixée au fond 10 de la pièce 8 et à la structure 3 envisagée.The opposite end of the part 8 is equipped with two vertical flanges 9 b (fig. 6 and 7) which are directly fixed to the other structure 3, this joining being completed by a spacer 9 c fixed to the bottom 10 of the part 8 and to the structure 3 envisaged.

Contre l'ensemble 8-11 ainsi fixé aux structures 3 du métier vient s'arrimer la mécanique 1 (fig. 3, 4 et 5). Cet arrimage est opéré à l'aide de la traverse inférieure 13 du caisson 11, et au moyen de tirants supérieurs référencés 17 en fig. 5.Against the assembly 8-11 thus fixed to the structures 3 of the loom comes to dock the mechanics 1 (fig. 3, 4 and 5). This stowage is operated using the lower cross member 13 of the box 11, and by means of upper tie rods referenced 17 in FIG. 5.

Pour le montage articulé des leviers de renvoi 7 du système de tirage, on a prévu deux axes transversaux 18 et 19 (fig. 6, 7 et 8) qui sont portés par des paliers 20 fixés aux ailes 9 de la pièce 8 pour ce qui est de l'axe 19, aux oreilles 16 pour ce qui est de l'axe 18.For the articulated mounting of the return levers 7 of the pulling system, two transverse axes 18 and 19 are provided (fig. 6, 7 and 8) which are carried by bearings 20 fixed to the wings 9 of the part 8 so that is from axis 19, to ears 16 with respect to axis 18.

Le système de tirage est avantageusement protégé par un couvercle démontable 21 qui est bien entendu découpé d'ouvertures 21a (fig. 5 et 6) pour le passage des bielles verticales 22 associées aux cadres de lisses CL et aux leviers de renvoi 7.The pulling system is advantageously protected by a removable cover 21 which is of course cut out from openings 21 a (FIGS. 5 and 6) for the passage of the vertical connecting rods 22 associated with the heald frames CL and the return levers 7.

On conçoit qu'on obtient finalement une construction très robuste et très rigide qui s'oppose à toute apparition de vibrations parasites, quelle que soit la cadence de fonctionnement de la mécanique 1. Le montage du bâti-support 8-11 suivant l'invention contre les structures 3 du métier peut être très aisément opéré.It is understood that ultimately a very robust and very rigid construction is obtained which prevents any appearance of parasitic vibrations, whatever the rate of operation of the mechanics 1. The mounting of the support frame 8-11 according to the invention against structures 3 of the trade can be very easily operated.

On conçoit que si la présence du caisson 11 interposé, à la manière d'une interface, entre la pièce en U 8 et la mécanique 1 semble particulièrement avantageuse par suite du renforcement obtenu, elle n'est toutefois pas indispensable, la pièce 8 étant susceptible, moyennant une épaisseur appropriée, de former directement support pour la fixation de la mécanique.It is understood that if the presence of the box 11 interposed, in the manner of an interface, between the U-shaped part 8 and the mechanics 1 seems particularly advantageous as a result of the reinforcement obtained, it is however not essential, the part 8 being capable, with an appropriate thickness, of directly forming a support for fixing the mechanics.
