Description

La présente invention concerne le domaine de l'industrie textile, notamment les guide-mèches de finisseurs, en particulier de frotteurs, et a pour objet un guide-mèche pourvu d'un dispositif destiné à éviter l'usure très rapide de certaines parties dudit guide-mèche.The present invention relates to the textile industry, in particular the drill guides of finishers, in particular of wipers, and relates to a drill guide provided with a device intended to prevent very rapid wear of certain parts of said drill guide.

Actuellement, les frotteurs sont généralement équipés de guide-mèches torsadés destinés à assurer le guidage de la mèche provenant du dispositif de frottage et allant vers la bobine.Currently, the wipers are generally fitted with twisted drill guides intended to guide the drill bit coming from the rubbing device and going towards the coil.

Au début de la torsade, c'est-à-dire sur la première spire, la mèche change de direction et prend un virage, ce qui a pour effet d'entraîner une usure très rapide de cette première spire.At the start of the twist, that is to say on the first turn, the wick changes direction and takes a turn, which has the effect of causing very rapid wear of this first turn.

En outre, le guide-mèche est soumis à un mouvement de débattement alternatif très rapide qui, par l'effet de l'inertie, contribue à casser la torsade à la hauteur de la première spire à l'endroit de l'usure par la mèche.In addition, the drill guide is subjected to a very rapid reciprocating movement which, by the effect of inertia, contributes to breaking the twist at the height of the first turn at the place of wear by the wick.

Les deux causes précitées, conjuguées, provoquent donc la casse des guide-mèches, la cause la plus grave étant l'usure de la torsade par la mèche, du fait qu'il n'est pas possible d'agir sur le mouvement alternatif du guide, ce mouvement faisant partie du processus de renvidage du frotteur.The two aforementioned causes, combined, therefore cause breakage of the drill guides, the most serious cause being the wear of the twist by the drill bit, since it is not possible to act on the reciprocating movement of the guide, this movement being part of the rewinding process of the wiper.

En outre, les guides torsadés usés ou cassés nécessitent un remplacement fréquent et coûteux entraînant des arrêts correspondants de la machine pour les interventions. De plus, un guide qui se déforme et se détache peut provoquer des dégâts considérables sur la machine et est toujours à l'origine d'une mèche irrégulière et de mauvaise qualité.In addition, worn or broken twisted guides require frequent and costly replacement resulting in corresponding machine stops for interventions. In addition, a guide which deforms and comes off can cause considerable damage to the machine and is always the cause of an irregular and poor quality drill bit.

La présente invention a pour but de pallier ces inconvénients.The present invention aims to overcome these drawbacks.

Elle a, en effet, pour objet un guide-mèche de finisseur, en particulier de frotteur, caractérisé en ce qu'il est pourvu d'une pièce de détour disposée au niveau du changement de direction de la mèche, à savoir à hauteur de la première spire du guide torsadé où la mèche prend un virage.It has, in fact, for its object a finisher drill guide, in particular a wiper, characterized in that it is provided with a bend piece disposed at the change of direction of the drill bit, namely at the height of the first turn of the twisted guide where the wick takes a turn.

L'invention sera mieux comprise, grâce à la description ci-après, qui se rapporte à un mode de réalisation préféré, donné à titre d'exemple non limitatif, et expliqué avec référence au dessin schématique annexé, dans lequel :

  • la figure l est une vue en élévation latérale et en coupe d'un guide-mèche conforme à l'invention, et
  • la figure 2 est une vue partielle en élévation frontale du guide-mèche suivant la figure l.
The invention will be better understood from the description below, which relates to a preferred embodiment, given by way of nonlimiting example, and explained with reference to the appended schematic drawing, in which:
  • FIG. 1 is a side elevation view in section of a drill guide according to the invention, and
  • FIG. 2 is a partial view in front elevation of the drill guide according to FIG.

Conformément à l'invention et comme le montrent, à titre d'exemple, les figures l et 2 du dessin annexé, le guide-mèche de finisseur, en particulier de frotteur, est pourvu d'une pièce de détour l disposée au niveau du changement de direction de la mèche 2, à savoir à hauteur de la première spire 3 du guide torsadé 4 où la mèche 2 prend un virage.In accordance with the invention and as shown, by way of example, in FIGS. 1 and 2 of the appended drawing, the finisher drill guide, in particular of a wiper, is provided with a bending piece l arranged at the level of the change of direction of the wick 2, namely at the level of the first turn 3 of the twisted guide 4 where the wick 2 takes a turn.

La pièce de détour l est avantageusement une pièce rapportée fixée sur le corps 5 de support du guide torsadé 4 de manière démontable au moyen d'une vis 6 ou analogue.The detour part 1 is advantageously an attached part fixed to the body 5 for supporting the twisted guide 4 in a removable manner by means of a screw 6 or the like.

Cette pièce l est, de préférence, réalisée en un métal ou en un alliage métallique de très grande dureté. Ce métal ou cet alliage peut, par exemple, être traité thermiquement afin de présenter une dureté de surface très élevée et donc une grande résistance à l'usure par la mèche.This part 1 is preferably made of a metal or a metal alloy of very high hardness. This metal or this alloy can, for example, be heat treated in order to have a very high surface hardness and therefore a high resistance to wear by the drill bit.

Selon une caractéristique de l'invention, la pièce l peut comporter, à l'endroit du passage de la mèche, un élément rapporté résistant à l'usure, en particulier en céramique.According to a characteristic of the invention, the part l can comprise, at the place of the passage of the wick, a wear-resistant insert, in particular ceramic.

Conformément à une autre caractéristique de l'invention, la pièce l peut être réalisée entièrement en céramique.According to another characteristic of the invention, the part l can be made entirely of ceramic.

Une telle prévision d'une partie en céramique ou d'une réalisation entièrement en céramique permet l'obtention d'une pièce l dont la résistance à l'usure par la mèche au niveau du passage de cette dernière est optimale.Such a prediction of a ceramic part or an entirely ceramic embodiment makes it possible to obtain a part l whose resistance to wear by the wick at the level of the passage of the latter is optimal.

Grâce à ce mode de réalisation, la mèche 2 prend son virage sur la pièce de détour l et non plus, comme dans les modes de réalisation connus à ce jour, sur la première spire 3 du guide torsadé 4, qui reste, de ce fait, totalement intacte, la mèche y passant en ligne droite. En effet, le phénomène de sciage de la spire 3 du guide torsadé 4 existant à ce jour peut être évité du fait que, contrairement aux guides existants qui ne peuvent pas subir de traitement thermique leur conférant une dureté superficielle qui les rendrait cassants, la pièce de détour l peut être très dure, tout en autorisant une souplesse du guide torsadé 4. Ainsi, l'usure est reportée sur la pièce de détour l qui est, en fait, un organe de dimension relativement faible, pouvant être facilement monté et démonté et d'un faible prix de revient.Thanks to this embodiment, the bit 2 takes its turn on the detour piece l and no longer, as in the embodiments known to date, on the first turn 3 of the twisted guide 4, which therefore remains , completely intact, the wick passing in a straight line. Indeed, the sawing phenomenon of the turn 3 of the twisted guide 4 existing to date can be avoided because, unlike existing guides which cannot undergo heat treatment giving them a surface hardness which would make them brittle, the part bend l can be very hard, while allowing flexibility of the twisted guide 4. Thus, wear is transferred to the bend piece l which is, in fact, a relatively small member, which can be easily assembled and disassembled and a low cost price.

Le mode de réalisation conforme à l'invention présente donc l'avantage d'éviter des guides torsadés usés ou cassés sur le frotteur et d'obtenir ainsi une mèche dont la qualité est constante.The embodiment according to the invention therefore has the advantage of avoiding worn or broken twisted guides on the wiper and thus obtaining a wick whose quality is constant.

Grâce à l'invention il est possible de réaliser un guide-mèche de finisseur, en particulier de frotteur, ne présentant pratiquement plus de pièce usée.Thanks to the invention it is possible to produce a finisher drill guide, in particular a wiper, having practically no more worn parts.

Bien entendu, l'invention n'est pas limitée au mode de réalisation décrit et représenté au dessin annexé. Des modifications restent possibles, notamment du point de vue de la constitution des divers éléments ou par substitution d'équivalents techniques, sans sortir pour autant du domaine de protection de l'invention.Of course, the invention is not limited to the embodiment described and shown in the accompanying drawing. Modifications remain possible, in particular from point of view of the constitution of the various elements or by substitution of technical equivalents, without thereby departing from the scope of protection of the invention.
