Description

La présente invention concerne le domaine du traitement des fibres par peignage et a pour objet une brosse circulaire de peigneuse rectiligne.The present invention relates to the field of fiber treatment by combing and relates to a circular brush for a straight combing machine.

Actuellement, sur une peigneuse rectiligne, les fibres courtes, dont on peut régler la longueur, sont séparées des fibres longues par un peigne circulaire et par un peigne fixe.Currently, on a straight comb, the short fibers, the length of which can be adjusted, are separated from the long fibers by a circular comb and by a fixed comb.

L'ensemble des fibres courtes et très courtes ainsi éliminées forme la blousse, qui est amenée par le peigne circulaire sur la brosse circulaire, laquelle est déchargée de ladite blousse par le peigneur ou doffer. Ensuite, la blousse est détachée du doffer et récupérée dans un bac à blousse.All of the short and very short fibers thus eliminated form the blister, which is brought by the circular comb onto the circular brush, which is discharged from said blister by the doffer or doffer. Then, the pod is detached from the doffer and collected in a pod bin.

Dans les modes de réalisation existants, la brosse circulaire pénètre dans les barettes du peigne circulaire afin d'en extraire la blousse et de l'amener au doffer. La brosse circulaire présente une vitesse de rotation plus élevée que celle du peigne circulaire, afin de réaliser un nettoyage efficace de ce dernier.In the existing embodiments, the circular brush penetrates into the barrettes of the circular comb in order to extract the blister therefrom and bring it to the doffer. The circular brush has a higher speed of rotation than that of the circular comb, in order to achieve effective cleaning of the latter.

Ainsi, en pénétrant dans les barettes du peigne circulaire, les touffes de la brosse circulaire sont repoussées en arrière et, au bout d'un certain temps de fonctionnement, ces touffes restent en position repliée vers l'arrière de sorte que l'efficacité de la brosse circulaire est quasiment nulle, les touffes ne pénétrant plus entre les barettes du peigne circulaire et n'en sortant plus la blousse.Thus, when entering the barrettes of the circular comb, the tufts of the circular brush are pushed back and, after a certain period of operation, these tufts remain in the folded back position so that the effectiveness of the circular brush is almost zero, the tufts no longer penetrating between the barrettes of the circular comb and no longer taking out the brush.

En outre, l'efficacité du peigne circulaire s'amoindrit considérablement par suite d'un engorgement dû à la blousse qui n'est plus évacuée et la brosse circulaire doit être regarnie souvent, ce qui entraîne une dépense complémentaire de matériel et de main-d'oeuvre ainsi que de nombreux arrêts de la machine, diminuant d'autant le rendement de cette dernière.In addition, the effectiveness of the circular comb decreases considerably as a result of engorgement due to the bush which is no longer evacuated and the circular brush must be replenished often, which involves an additional expense of material and labor as well as numerous machine stoppages, thereby reducing the efficiency of the latter.

Pour obvier à cet inconvénient, et plus particulièrement pour éviter des regarnissages trop fréquents, il a été proposé de retourner la brosse circulaire afin de la faire travailler en sens inverse, les touffes repliées pouvant alors à nouveau attaquer le peigne circulaire.To overcome this drawback, and more particularly to avoid too frequent relining, it has been proposed to turn the circular brush in order to make it work in the opposite direction, the tufts folded back then being able to attack the circular comb again.

Toutefois, dans ce procédé, les arrêts de la machine sont quand même nécessaires, de sorte que le coût d'exploitation de la peigneuse est également renchéri.However, in this process, the machine stops are still necessary, so that the operating cost of the combing machine is also increased.

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

Elle a, en effet, pour objet une brosse circulaire de peigneuse rectiligne, caractérisée en ce que ses touffes sont implantées de manière inclinée en direction de son sens de rotation et en ce que, en cours de rotation, elle coopère avec un dispositif de nettoyage et de redressement des touffes.It has, in effect, for a circular brush of a straight combing machine, characterized in that its tufts are implanted in an inclined direction towards its direction of rotation and in that, during rotation, it cooperates with a cleaning device and straightening tufts.

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 aux dessins schématiques annexés, dans lesquels :

  • la figure 1 est une vue en élévation latérale et en coupe d'une peigneuse rectiligne comportant la brosse conforme à l'invention ;
  • la figure 2 est une vue en élévation latérale et en coupe, à plus grande échelle, de la brosse circulaire selon l'invention ;
  • la figure 3 est une vue analogue à celle de la figure 1 d'une variante de réalisation de l'invention, et
  • la figure 4 est une vue en élévation frontale de la brosse circulaire et d'un dispositif de nettoyage et de redressement des touffes.
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 drawings, in which:
  • Figure 1 is a side elevational view in section of a straight combing machine comprising the brush according to the invention;
  • Figure 2 is a side elevational view in section, on a larger scale, of the circular brush according to the invention;
  • FIG. 3 is a view similar to that of FIG. 1 of an alternative embodiment of the invention, and
  • Figure 4 is a front elevational view of the circular brush and a device for cleaning and straightening tufts.

Les figures 1 et 3 des dessins annexés représentent un ensemble peigne circulaire 1, brosse circulaire 2, doffer 3 ou peigneur et peigne 4 détacheur de la blousse d'une peigneuse rectiligne.Figures 1 and 3 of the accompanying drawings show a set of circular comb 1, circular brush 2, doffer 3 or comb and comb 4 detacher of the sleeve of a straight combing machine.

Conformément à l'invention, et comme le montrent, plus particulièrement, à titre d'exemples, les figures 1 à 3 des dessins annexés, la brosse circulaire 2 de peigneuse rectiligne est caractérisée en ce que ses touffes 5 sont implantées dans des logements 6 inclinés en direction de son sens de rotation et en ce que, en cours de rotation, elle coopère avec un dispositif 7 de nettoyage et de redressement des touffes 5.In accordance with the invention, and as shown more particularly by way of examples, Figures 1 to 3 of the accompanying drawings, the circular brush 2 of a straight combing machine is characterized in that its tufts 5 are located in housings 6 inclined in the direction of its direction of rotation and in that, during rotation, it cooperates with a device 7 for cleaning and straightening the tufts 5.

Les touffes 5 sont implantées dans les logements 6 qui sont aménagés dans le corps de la brosse circulaire 2. Les logements 6 sont avantageusement inclinés par rapport au rayon d'un angle compris entre 5° et 30° en direction du sens de rotation (figure 2).The tufts 5 are located in the housings 6 which are arranged in the body of the circular brush 2. The housings 6 are advantageously inclined with respect to the radius of an angle of between 5 ° and 30 ° in the direction of the direction of rotation (figure 2).

En cours de fonctionnement, la blousse, qui est amenée par le peigne circulaire 1 qui tourne dans le sens de la flèche 8, est prise par la brosse circulaire 2 qui tourne dans le sens de la flèche 9 et a une vitesse circonférentielle plus rapide que celle du peigne circulaire 1. Le doffer ou peigneur 3, qui tourne dans le sens de la flèche 10 et à une vitesse circonférentielle plus lente que la brosse circulaire 2, reprend la blousse de cette dernière et en est déchargée en cours de rotation par le peigne détacheur 4, animé d'un mouvement oscillant dans le sens de la double flèche 11, ce peigne 4 la faisant tomber dans le bac à blousse de la peigneuse (non représenté).During operation, the bush, which is brought by the circular comb 1 which rotates in the direction of the arrow 8, is taken up by the circular brush 2 which rotates in the direction of the arrow 9 and has a faster circumferential speed than that of the circular comb 1. The doffer or comb 3, which rotates in the direction of the arrow 10 and at a circumferential speed slower than the circular brush 2, picks up the sleeve of the latter and is discharged during rotation by the detacher comb 4, animated by an oscillating movement in the direction of the double arrow 11, this comb 4 causing it to fall into the comb tray of the comber (not shown).

Le dispositif 7 de nettoyage et de redressement des touffes 5 est avantageusement constitué, comme le montre la figure 1, par un marteau 12 à une ou plusieurs têtes qui tourne, suivant la flèche 13, de manière à engrener avec les touffes 5 de la brosse circulaire 2, c'est-à-dire dans une même direction tangentielle. Ainsi, lors de sa rotation dans le sens de la flèche 13, le marteau 12 tape sur les touffes 5 qui passent devant lui et les redresse de telle manière qu'elles soient de nouveau droites et d'attaque pour le prochain tour de nettoyage du peigne circulaire 1. Le marteau 12 contribue, en outre, également au maintien de la propreté de la brosse circulaire 2 par un effet de nettoyage des touffes 5 la constituant.The device 7 for cleaning and straightening tufts 5 is advantageously constituted, as shown in Figure 1, by a hammer 12 with one or more heads which rotates, according to arrow 13, so as to mesh with the tufts 5 of the circular brush 2, that is to say in the same tangential direction . Thus, during its rotation in the direction of the arrow 13, the hammer 12 taps on the tufts 5 which pass in front of it and straightens them so that they are again straight and of attack for the next cleaning round of the circular comb 1. The hammer 12 also contributes to maintaining the cleanliness of the circular brush 2 by a cleaning effect of the tufts 5 constituting it.

Les figures 3 et 4 des dessins annexés représentent une variante de réalisation de l'invention, dans laquelle le dispositif 7 de nettoyage et de redressement des touffes 5 est constitué par une installation de jet d'air comprimé comportant un conduit 14 d'amenée de l'air comprimé et des busettes 15 de soufflage dirigées vers les touffes 5, le conduit 14 étant animé d'un mouvement de va-et-vient parallèle à l'axe de la brosse circulaire 2 suivant la flèche 16 (figure 4). Ce mode de réalisation permet un redressement et un nettoyage par débourrage des touffes 5 au cours de la rotation de la brosse 2, de sorte que cette dernière est continuellement d'attaque pour le prochain tour de nettoyage du peigne 1 et est maintenue dans un état de propreté parfait.Figures 3 and 4 of the accompanying drawings show an alternative embodiment of the invention, in which the device 7 for cleaning and straightening the tufts 5 is constituted by a compressed air jet installation comprising a duct 14 for supplying compressed air and blowing nozzles 15 directed towards the tufts 5, the conduit 14 being driven back and forth parallel to the axis of the circular brush 2 along arrow 16 (Figure 4). This embodiment allows straightening and cleaning by cleaning the tufts 5 during the rotation of the brush 2, so that the latter is continuously attacked for the next cleaning round of the comb 1 and is maintained in a state perfect cleanliness.

Grâce à l'invention, il est possible d'obtenir un meilleur dégagement de la blousse du peigne circulaire 1 ainsi qu'un meilleur nettoyage de ce dernier.Thanks to the invention, it is possible to obtain better clearance of the circular comb bush 1 as well as better cleaning of the latter.

En outre, du fait de l'inclinaison des touffes 5 vers l'avant, en direction du sens de rotation de la brosse circulaire 2, leur durée de vie est considérablement prolongée avant qu'elle n'arrive dans une position repliée en arrière en direction du corps de la brosse 2. Par ailleurs, le peigne circulaire 1 étant nettoyé d'une manière plus efficace, le produit obtenu est également de meilleure qualité.In addition, due to the inclination of the tufts 5 forwards, in the direction of the direction of rotation of the circular brush 2, their lifespan is considerably extended before it arrives in a folded back position towards the body of the brush 2. Furthermore, the circular comb 1 being cleaned more efficiently, the product obtained is also of better quality.

Enfin, la durée de vie des touffes 5 étant prolongée de manière très significative, le regarnissage de la brosse circulaire 2 n'est plus nécessaire qu'à des intervalles de temps très longs, de sorte que de nombreux arrêts de la machine sont évités, permettant ainsi l'obtention d'un rendement élevé de ladite machine et un gain de main-d'oeuvre et de matériel appréciable.Finally, the life of the tufts 5 being extended very significantly, relining of the circular brush 2 is no longer necessary except at very long time intervals, so that numerous stops of the machine are avoided, thus allowing a high efficiency of said machine to be obtained and an appreciable gain in labor and material.

Bien entendu, l'invention n'est pas limitée aux modes de réalisation décrit et représenté aux dessins annexés. 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 embodiments described and shown in the accompanying drawings. Modifications remain possible, in particular from the 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.
