Definitions
- the present invention relates to weaving looms and it relates more particularly to casement cam blocks which are intended to control the oscillating comb holder.
- devices of this type include a casing inside which are mounted two shafts which are oriented parallel to each other and whose ends protrude on either side of the lateral faces of said casing. On one of these shafts is wedged a set of conjugate cams against which roll two follower rollers carried by a double lever itself made angularly integral with the other shaft, things being arranged so that the continuous rotation of the first tree determines an oscillating movement of the second.
- the oscillating control thereof requires at least two blocks of cams of the aforementioned type, so that the shafts of these two blocks must be joined together in pairs using fittings and intermediate trees. It is understood, however, that this assembly constitutes delicate work because it is obviously essential to avoid any misalignment, even slight.
- the present invention mainly intends to remedy, which essentially consists in producing each of the shafts of the cam block in the form of sleeves capable of being axially traversed by axes of any desired length.
- Fig. 1 is a schematic vertical section of a block of swinging cams produced in accordance with this invention.
- Fig. 2 is a horizontal section of this device along the plane indicated in II-II in FIG. 1; in this figure we have shown in II the section plane of fig. 1.
- the reference 1 designates a casing formed by the sealed assembly of two parts, the opposite main walls of this casing 1 being equipped with two pairs of ball or needle bearings 2.
- the aligned bearings 2 support in rotation a sleeve 3, respectively 4, oriented parallel to each other; the ends of each of these sleeves 3, 4 protrude slightly beyond the side walls of the casing 1 in order to determine end pieces which are split longitudinally to cooperate with clamps 5, the role of which will be explained below.
- the central part of the sleeve 3 is shaped so as to form a double lever 6, each of the ends of which is equipped with a follower roller 7.
- the central part of the sleeve 4 is arranged so as to present two parallel discs 8 , profiled in the manner of the two conjugate elements of a double cam, and it is against the periphery of these discs 8 that the two rollers roll 7. It is conceivable under these conditions that if it is assumed that the sleeve 4 is driven in continuous rotation, the sleeve 3 will on the other hand be driven in an oscillating movement, in the same way as in conventional cam blocks.
- each of the sleeves 3 and 4 is capable of being crossed by a shaft 9, respectively 10, the first of these shafts being made integral with the arms which support the comb holder of the loom considered, while the second is angularly linked to the main tree of this profession.
- These two shafts 9 and 10 are obviously capable of having any length, so that whatever the width of the loom and the length of the oscillating comb holder, there is no need to connect any shafts, the same shaft 9 or 10 being capable of passing axially through any number of devices while being fixed to the corresponding sleeve 3 or 4 of each of them by means of the clamps 5.

Description
La présente invention a trait aux métiers à tisser et elle concerne plus particulièrement les blocs de cames à battant qui sont destinés à assurer la commande du porte-peigne oscillant.The present invention relates to weaving looms and it relates more particularly to casement cam blocks which are intended to control the oscillating comb holder.
On sait que dans les constructions classiques, voir par exemple FR-A-2 314 282, les dispositifs de ce type comprennent un carter à l'intérieur duquel sont montés deux arbres qui sont orientés parallèlement l'un à l'autre et dont les extrémités dépassent de part et d'autre des faces latérales dudit carter. Sur l'un de ces arbres est calé un jeu de cames conjuguées contre lesquelles roulent deux galets suiveurs portés par un levier double lui-même rendu angulairement solidaire de l'autre arbre, les choses étant agencées de façon à ce que la rotation continue du premier arbre détermine un mouvement oscillant du second.We know that in conventional constructions, see for example FR-A-2 314 282, devices of this type include a casing inside which are mounted two shafts which are oriented parallel to each other and whose ends protrude on either side of the lateral faces of said casing. On one of these shafts is wedged a set of conjugate cams against which roll two follower rollers carried by a double lever itself made angularly integral with the other shaft, things being arranged so that the continuous rotation of the first tree determines an oscillating movement of the second.
Compte tenu de la longueur du porte-peigne, la commande oscillante de celui-ci nécessite au moins deux blocs de cames du type susvisé, de telle sorte que les arbres de ces deux blocs doivent être réunis deux à deux à l'aide de raccords et d'arbres intermédiaires. On conçoit toutefois que cet assemblage constitue un travail délicat car il est évidemment indispensable d'éviter tout défaut d'alignement, même minime.Given the length of the comb holder, the oscillating control thereof requires at least two blocks of cams of the aforementioned type, so that the shafts of these two blocks must be joined together in pairs using fittings and intermediate trees. It is understood, however, that this assembly constitutes delicate work because it is obviously essential to avoid any misalignment, even slight.
C'est à cet inconvénient qu'entend principalement remédier la présente invention, laquelle consiste essentiellement à réaliser chacun des arbres du bloc de cames sous la forme de manchons aptes à être traversés axialement par des axes de toute longueur désirée.It is to this drawback that the present invention mainly intends to remedy, which essentially consists in producing each of the shafts of the cam block in the form of sleeves capable of being axially traversed by axes of any desired length.
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 coupe verticale schématique d'un bloc de cames à battant réalisé conformément à la présente invention.
Fig. 2 est une coupe horizontale de ce dispositif suivant le plan indiqué en II-II en fig. 1 ; sur cette figure on a fait apparaître en I-I le plan de coupe de fig. 1.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 a schematic vertical section of a block of swinging cams produced in accordance with this invention.
Fig. 2 is a horizontal section of this device along the plane indicated in II-II in FIG. 1; in this figure we have shown in II the section plane of fig. 1.
Sur ce dessin, la référence 1 désigne un carter formé par l'assemblage étanche de deux pièces, les parois principales opposées de ce carter 1 étant équipées des deux paires de roulements à billes ou à aiguilles 2. Les roulements 2 alignés supportent à rotation un manchon 3, respectivement 4, orientés parallèlement l'un à l'autre ; les extrémités de chacun de ces manchons 3 ,4 dépassent légèrement au-delà des parois latérales du carter 1 afin de déterminer des embouts qui sont fendus longitudinalement pour coopérer avec des brides de serrage 5, dont le rôle sera exposé plus loin.In this drawing, the
La partie centrale du manchon 3 est conformée de façon à former un levier double 6 dont chacune des extrémités est équipée d'un galet suiveur 7. De la même manière, la partie centrale du manchon 4 est agencée de façon à présenter deux disques parallèles 8, profilés à la manière des deux éléments conjugués d'une came double, et c'est contre la périphérie de ces disques 8 que roulent les deux galets 7. On conçoit dans ces conditions que si l'on suppose que le manchon 4 est entraîné en rotation de manière continue, le manchon 3 sera par contre animé d'un mouvement oscillant, de la même manière que dans les blocs à cames classiques.The central part of the
On comprend toutefois que la forme de réalisation tubulaire des organes 3 et 4 simplifie de manière considérable l'implantation du bloc de cames sur le métier. Effectivement, chacun des manchons 3 et 4 est susceptible d'être traversé par un arbre 9, respectivement 10, le premier de ces arbres étant rendu solidaire des bras qui supportent le porte-peigne du métier considéré, tandis que le second est lié angulairement à l'arbre principal de ce métier.It is understood, however, that the tubular embodiment of the
Ces deux arbres 9 et 10 sont évidemment susceptibles de présenter une longueur quelconque, si bien que quelles que soient la largeur du métier et la longueur du porte-peigne oscillant, on se dispense de tout raccordement d'arbres, le même arbre 9 ou 10 étant susceptible de traverser axialement un nombre quelconque de dispositifs en étant fixé au manchon 3 ou 4 correspondant de chacun de ceux-ci à l'aide des brides de serrage 5.These two
Il va de soi dans ces conditions qu'un tel agencement assure une géométrie et une rigidité bien plus favorables que dans les constructions classiques à raccords.It goes without saying under these conditions that such an arrangement provides a geometry and rigidity much more favorable than in conventional constructions with fittings.
