Description

La présente invention concerne le domaine de l'industrie textile et plus particulièrement du nettoyage des machines textiles, notamment durant leur fonctionnement, et a pour objet un appareil pour l'élimination des fibres et des duvets textiles.The present invention relates to the field of the textile industry and more particularly to the cleaning of textile machines, in particular during their operation, and relates to an apparatus for removing fibers and textile down.

Il existe actuellement déjà différents types d'appareils pour le maintien de la propreté des machines textiles, notamment en cours de fonctionnement, permettant par la récupération des fibres et des duvets textiles de prévenir les enroulements de fibres textiles autour des éléments en rotation desdites machines, réduisant ainsi les risques de casse de fil et, par conséquent, les arrêts de machines et les interventions qui en découlent.There are currently already different types of apparatus for maintaining the cleanliness of textile machines, in particular during operation, making it possible, by recovering fibers and textile duvets, to prevent windings of textile fibers around the rotating elements of said machines, thereby reducing the risk of wire breakage and, consequently, machine stoppages and the resulting interventions.

Ces appareils sont, en général, principalement composés, d'une part, d'un corps essentiellement creux, constitué par un carter et par une poignée de préhension, d'autre part, d'une broche maintenue par une de ses extrémités, avec faculté de rotation, dans ledit carter et solidaire d'un volant d'inertie et, enfin, d'un dispositif d'entraînement en rotation de l'ensemble broche-volant d'inertie, la rotation de ladite broche entraînant l'enroulement autour d'elle des duvets et/ou des fibres qui entrent en contact avec elle.These devices are, in general, mainly composed, on the one hand, of an essentially hollow body, constituted by a casing and by a grip handle, on the other hand, of a spindle held by one of its ends, with faculty of rotation, in said casing and integral with a flywheel and, finally, with a device for driving in rotation of the spindle-flywheel assembly, the rotation of said spindle causing the winding around down and / or fibers coming into contact with it.

Néanmoins ces appareils existants présentent encore de nombreux inconvénients.However, these existing devices still have many drawbacks.

En effet, aucun n'autorise un changement rapide de la broche et, notamment, sans démontage du corps et/ou du carter. En outre, l'utilisation d'un ou de plusieurs paliers glissants sans roulement pour le guidage en rotation de la broche et/ou du volant d'inertie entraîne, d'une part, une usure importante au niveau du ou desdits paliers et ne permet pas, d'autre part, d'atteindre des vitesses de rotation élevées, ni des durées importantes de rotation de l'ensemble broche-volant d'inertie lancé.Indeed, none authorizes a rapid change of the spindle and, in particular, without dismantling the body and / or the casing. In addition, the use of one or more sliding bearings without bearings for guiding the spindle and / or the flywheel in rotation results, on the one hand, in significant wear at the level of said bearing or bearings and does not not allow, on the other hand, to reach high rotational speeds, nor long periods of rotation of the spindle-flywheel assembly launched.

Il est donc nécessaire d'actionner fréquemment le dispositif d'entraînement en rotation pour garantir une vitesse de rotation de la broche permettant un enroulement rapide et efficace des duvets ou fibres textiles autour de cette dernière.It is therefore necessary to frequently actuate the rotational drive device to guarantee a spindle rotation speed allowing rapid and efficient winding of down or textile fibers around the latter.

Par ailleurs, du fait de la longueur de la broche, les appareils existants sont souvent déséquilibrés et nécessitent, par conséquent, pour leur manipulation, un effort supplémentaire de la part de l'utilisateur, notamment au niveau du poignet. La présente invention a pour but de pallier les inconvénients précités.Furthermore, due to the length of the spindle, existing devices are often unbalanced and therefore require, for their manipulation, an additional effort on the part of the user, in particular at the wrist. The present invention aims to overcome the aforementioned drawbacks.

Elle a, en effet, pour objet un appareil pour l'élimination des fibres et des duvets textiles, principalement composé, d'une part, d'un corps essentiellement creux, constitué par un carter et par une poignée de préhension, d'autre part, d'une broche disposée partiellement, avec faculté de rotation, dans ledit carter et solidaire d'un volant d'inertie et, enfin, d'un dispositif d'entraînement en rotation de l'ensemble broche-volant d'inertie, caractérisé en ce que la broche est assujettie en translation au carter au moyen d'un dispositif de fixation amovible et accessible de l'extérieur, sans démontage dudit corps creux ou dudit carter, permettant ainsi un changement rapide de ladite broche.It has, indeed, for its object an apparatus for removing fibers and textile down, mainly composed, on the one hand, of an essentially hollow body, constituted by a casing and by a grip handle, on the other hand part, of a spindle partially arranged, with faculty of rotation, in said casing and integral with a flywheel and, finally, of a device for driving in rotation of the spindle-flywheel assembly, characterized in that the spindle is subject in translation to the casing by means of a removable fixing device and accessible from the outside, without disassembly of said hollow body or of said casing, thus allowing rapid change of said spindle.

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 écorchée en élévation latérale de l'appareil conforme à l'invention, et
  • la figure 2 est une vue en coupe selon A-A de l'appareil représenté à la figure 1.
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:
  • FIG. 1 is a cutaway view in side elevation of the apparatus according to the invention, and
  • Figure 2 is a sectional view along AA of the apparatus shown in Figure 1.

Conformément à l'invention, et comme le montrent les figures 1 et 2 des dessins annexés, l'appareil pour l'élimination des fibres et des duvets textiles est principalement composé, d'une part, d'un corps 1 essentiellement creux, constitué par un carter 2 et par une poignée de préhension 3, d'autre part, d'une broche 4 disposée partiellement, avec faculté de rotation, dans ledit carter 2 et solidaire d'un volant d'inertie 5 et, enfin, d'un dispositif 6 d'entraînement en rotation de l'ensemble broche 4 -volant d'inertie 5, la broche 4 étant assujettie en translation au carter 2 au moyen d'un dispositif 7 de fixation amovible et accessible de l'extérieur, sans démontage dudit corps 1 creux ou dudit carter 2, permettant ainsi un changement rapide de ladite broche 4 par extraction hors dudit carter 2.According to the invention, and as shown in Figures 1 and 2 of the accompanying drawings, the apparatus for removing fibers and textile down is mainly composed, on the one hand, of an essentially hollow body 1, consisting by a casing 2 and by a gripping handle 3, on the other hand, a spindle 4 disposed partially, with faculty of rotation, in said casing 2 and integral with a flywheel 5 and, finally, of a device 6 for driving in rotation the spindle assembly 4-flywheel 5, the spindle 4 being subject in translation to the casing 2 by means of a removable fixing device 7 accessible from the outside, without dismantling said hollow body 1 or said casing 2, thus allowing a rapid change of said spindle 4 by extraction from said casing 2.

Selon une première caractéristigue de l'invention, représentée à la figure 1 des dessins annexés, l'ensemble broche 4 -volant d'inertie 5 est guidé en rotation par au moins deux paliers 8, 8′ à roulement 9, 9′ .According to a first characteristic of the invention, represented in FIG. 1 of the accompanying drawings, the spindle 4-flywheel 5 assembly is guided in rotation by at least two bearings 8, 8 ′ with bearings 9, 9 ′.

Ainsi, les frottements au niveau des paliers 8, 8′ sont réduits au minimum, permettant, d'une part, d'atteindre des vitesses de rotation de l'ensemble broche 4 -volant d'inertie 5 très élevées et, d'autre part, de conserver la vitesse de rotation acquise pendant une durée importante. En outre, il sera également possible de réduire la taille et la masse du volant d'inertie 5 et, par conséquent, la taille et la masse de l'appareil conforme à l'invention, sans diminuer notablement les performances dudit appareil.Thus, the friction at the bearings 8, 8 ′ is reduced to a minimum, making it possible, on the one hand, to achieve very high speeds of rotation of the spindle 4-flywheel assembly 5 and, on the other hand apart, to maintain the speed of rotation acquired for a significant period. In addition, it will also be possible to reduce the size and mass of the flywheel 5 and, consequently, the size and mass of the device according to the invention, without significantly reducing the performance of said device.

Comme le montre également la figure 1 des dessins annexés, le volant d'inertie 5 est, d'une part, disposé à l'intérieur du carter 2, d'autre part, monté directement sur un palier 8 à roulement 9 et, enfin, situé dans la partie arrière dudit carter 2, opposée à l'extrémité libre 10 de la broche 4, de manière à servir de contrepoids à ladite broche 4 par rapport à la poignée de préhension 3. Il en résulte un bon équilibrage de l'appareil conforme à l'invention dans la main de l'utilisateur et donc, une tenue facilitée dudit appareil, du fait du report de masse résultant de la disposition spécifique du volant d'inertie 5 dans le corps creux 1 et par rapport à la broche 4.As also shown in FIG. 1 of the accompanying drawings, the flywheel 5 is, on the one hand, disposed inside the casing 2, on the other hand, mounted directly on a bearing 8 with rolling bearing 9 and, finally , located in the rear part of said casing 2, opposite the free end 10 of pin 4, so as to serve counterweight to said spindle 4 relative to the gripping handle 3. This results in a good balancing of the device according to the invention in the hand of the user and therefore, easier holding of said device, due to the postponement mass resulting from the specific arrangement of the flywheel 5 in the hollow body 1 and relative to the spindle 4.

Conformément à une caractéristique de l'invention, représentée à la figure 1 des dessins annexés, le dispositif 7 de fixation de la broche 4 est accessible de l'extérieur au moyen d'un orifice 11 ménagé dans le carter 2 et fermé par un bouchon 12 amovible.In accordance with a characteristic of the invention, represented in FIG. 1 of the accompanying drawings, the device 7 for fixing the spindle 4 is accessible from the outside by means of an orifice 11 formed in the casing 2 and closed by a plug. 12 removable.

Selon une première variante de réalisation de l'invention, non représentée aux dessins annexés, le dispositif 7 de fixation de la broche 4 se présente sous la forme soit d'une douille filetée, soit d'une rondelle élastique ou encore d'un clip, disposé(e) à proximité immédiate de l'orifice 11.According to a first alternative embodiment of the invention, not shown in the accompanying drawings, the device 7 for fixing the spindle 4 is in the form of either a threaded sleeve, an elastic washer or a clip , arranged in the immediate vicinity of the orifice 11.

Conformément à une seconde variante de réalisation de l'invention, représentée à la figure 1 des dessins annexés, le dispositif 7 de fixation de la broche 4 se présente avantageusement sous la forme d'un écrou vissé sur une extrémité filetée 13 de la broche 4 et en appui sur la partie 14 libre en rotation du roulement 9 du palier 8 supportant le volant d'inertie 5.According to a second embodiment of the invention, shown in Figure 1 of the accompanying drawings, the device 7 for fixing the spindle 4 is advantageously in the form of a nut screwed onto a threaded end 13 of the spindle 4 and resting on the free rotating part 14 of the bearing 9 of the bearing 8 supporting the flywheel 5.

Le démontage de la broche 4 consiste, par conséquent, à enlever, tout d'abord, le bouchon 12, puis à dévisser l'écrou 7 au moyen d'un outil standard correspondant pénétrant dans le carter 2 par l'orifice 11 et, enfin, à extraire la broche 4 par l'orifice avant 15 du carter 2.The disassembly of the spindle 4 therefore consists in removing, first of all, the plug 12, then in unscrewing the nut 7 by means of a corresponding standard tool penetrating into the casing 2 through the orifice 11 and, finally, to extract the spindle 4 through the front orifice 15 of the casing 2.

L'interchangeabilité aisée des broches 4 permet d'adapter rapidement l'appareil, objet de l'invention, à des circonstances d'utilisation et à des machines particulières, par le choix de broches 4 correspondantes, à savoir, magnétiques, amagnétiques, de longueurs variables, etc..., mais également de changer une broche 4 abimée.The easy interchangeability of the pins 4 makes it possible to quickly adapt the device, object of the invention, to circumstances of use and to particular machines, by the choice of corresponding pins 4, namely, magnetic, non-magnetic, variable lengths, etc ..., but also to change a damaged pin 4.

Comme le montrent également les figures 1 et 2 des dessins annexés, le dispositif 6 d'entraînement en rotation de l'ensemble broche 4 - volant d'inertie 5 est principalement constitué, d'une part, par une gâchette 16 soumise à l'action d'un ressort 17 à compression et munie d'un secteur denté 18 et, d'autre part, par un pignon 19 engrenant avec ledit secteur denté 18 et pourvu d'une roue dentée 20 coopérant directement avec un filetage 21 correspondant de la broche 4, permettant ainsi de réaliser un entraînement direct de la broche 4, d'où il résulte une plus grande robustesse et une complexité moindre de la chaîne cinématique constituée par le dispositif 6 d'entraînement en rotation. En outre, l'obtention d'un sens de rotation de la broche 4 à gauche, par la réalisation d'une roue dentée 20 et d'un filetage 21 correspondants, autorise l'aménagement d'une extrémité filetée 13 de réalisation standard, c'est-à-dire avec un filetage à droite.As also shown in Figures 1 and 2 of the accompanying drawings, the device 6 for rotating the spindle 4 - flywheel 5 assembly consists mainly, on the one hand, of a trigger 16 subjected to the action of a compression spring 17 and provided with a toothed sector 18 and, on the other hand, by a pinion 19 meshing with said toothed sector 18 and provided with a toothed wheel 20 cooperating directly with a corresponding thread 21 of the spindle 4, thus making it possible to directly drive spindle 4, which results in greater robustness and less complexity of the kinematic chain formed by the device 6 for driving in rotation. In addition, obtaining a direction of rotation of the spindle 4 to the left, by producing a toothed wheel 20 and a corresponding thread 21, allows the fitting of a threaded end 13 of standard construction, i.e. with right-hand thread.

Conformément à une caractéristique de l'invention, représentée à la figure 2 des dessins annexés, l'entraînement en rotation de la roue dentée 20 par le pignon 19 est réalisé au moyen d'un dispositif de roue libre 20', monté sur le pignon 19 dans la roue dentée 20 et les solidarisent lors de l'actionnement de la gâchette 16 par l'utilisateur.In accordance with a characteristic of the invention, shown in FIG. 2 of the accompanying drawings, the gearwheel 20 is driven in rotation by the pinion 19 by means of a freewheel device 20 ′, mounted on the pinion 19 in the toothed wheel 20 and secure them when the trigger 16 is actuated by the user.

En effet, lorsque la gâchette 16 est actionnée, le secteur denté 18 entraîne le pignon 19 qui lui-même entraîne la roue dentée 20 par l'intermédiaire du dispositif de roue libre 20′ et permet ainsi la rotation de la broche 4 dans le sens correspondant, à savoir à gauche. Afin de diminuer les contraintes et les frottements pouvant affecter la rotation de la broche 4, le dispositif de roue libre 20′ se libère, lorsque la gâchette 16 est relachée ou n'est pas actionnée, et désolidarise le pignon 19 de la roue dentée 20, cette dernière pouvant alors continuer à tourner avec la broche 4.Indeed, when the trigger 16 is actuated, the toothed sector 18 drives the pinion 19 which itself drives the toothed wheel 20 by means of the freewheel device 20 ′ and thus allows the rotation of the spindle 4 in the direction corresponding, namely to the left. In order to reduce the stresses and friction which can affect the rotation of the spindle 4, the freewheel device 20 ′ is released, when the trigger 16 is released or is not actuated, and separates the pinion 19 from the toothed wheel 20 , this the latter can then continue to rotate with pin 4

Selon une autre caractéristique de l'invention, et comme le montrent les figures 1 et 2 des dessins annexés, le corps 1 creux est avantageusement composé de deux demi-corps 22, 22′ de conformation identique, comportant sur leurs faces internes des nervures 23 coopérant entre elles et/ou avec certains éléments mobiles 4 et 20, lors de l'assemblage des deux demi-corps 22 et 22' entre eux, permettant ainsi de réaliser un compartimentage du volume intérieur du corps 1 creux et, par conséquent, de limiter les dépôts de saletés dans ledit corps 1, notamment au niveau du dispositif 6 d'entraînement en rotation.According to another characteristic of the invention, and as shown in Figures 1 and 2 of the accompanying drawings, the hollow body 1 is advantageously composed of two half-bodies 22, 22 ′ of identical conformation, having on their internal faces ribs 23 cooperating with each other and / or with certain mobile elements 4 and 20, during the assembly of the two half-bodies 22 and 22 ′ between them, thus making it possible to partition the interior volume of the hollow body 1 and, consequently, to limit the deposits of dirt in said body 1, in particular at the level of the device 6 for driving in rotation.

Conformément à une caractéristique supplémentaire de l'invention, représentée aux figures 1 et 2 des dessins annexés, l'appareil conforme à l'invention comporte, en outre, une dragonne 24 fixée à l'extrémité libre de la poignée de préhension 3 au moyen d'un crochet 25 flexible, permettant de détacher ladite dragonne 24 du corps 1 de l'appareil, et de libérer, par conséquent, le poignet de l'utilisateur, lors d'une traction importante due, par exemple, à l'entraînement dudit appareil par des éléments tournants d'une machine textile.According to an additional characteristic of the invention, shown in Figures 1 and 2 of the accompanying drawings, the apparatus according to the invention further comprises a strap 24 fixed to the free end of the grip handle 3 by means a flexible hook 25, making it possible to detach said wrist strap 24 from the body 1 of the device, and consequently to release the wrist of the user, during heavy traction due, for example, to training of said device by rotating elements of a textile machine.

Le corps 1 creux, ainsi que la gâchette 16 et la dragonne 24 sont avantageusement réalisés en des matériaux synthétiques, préférentiellement thermoplastiques, alors que la broche 4 ainsi que le pignon 19 et la roue dentée 20 consistent en des métaux adéquats.The hollow body 1, as well as the trigger 16 and the wrist strap 24 are advantageously made of synthetic materials, preferably thermoplastic, while the spindle 4 as well as the pinion 19 and the toothed wheel 20 consist of suitable metals.

Enfin, les roulements 9 et 9′ sont de préférence des roulements étanches, graissés à vie.Finally, the bearings 9 and 9 ′ are preferably sealed bearings, lubricated for life.

Bien entendu, l'invention n'est pas limitée au mode 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 embodiment 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.
