Abstract

The present invention relates to a device for the continuous cleaning of the pins of a gill box for long textile fibres, said gill box consisting of a lower set of gill bars and an upper set of gill bars, each thus forming a crawler track which controls the sliver formed from the textile fibres, before the drawing by drawing cylinders. The device is characterised in that it is in the form of a means (1, 1') for blowing compressed air from the inside of each crawler track (2, 2') towards the outside on the part (7, 7') of each crawler track (2, 2') receiving the gill bars (3, 3') which have just left the sliver (4) received by the drawing cylinders (5). <IMAGE>

Description

La présente invention concerne le domaine textile, et a pour objet un dispositif de nettoyage permanent des ai­guilles d'un système d'étirage à aiguilles pour fibres tex­tiles longues, ledit système étant constitué par un champ de barrettes à aiguilles inférieur et un champ de barrettes à aiguilles supérieur, chacun formant ainsi une chenille qui contrôle le ruban formé des fibres textiles, avant étirage par des cylindres étireurs.The present invention relates to the textile field, and relates to a device for permanently cleaning the needles of a needle drawing system for long textile fibers, said system consisting of a field of lower needle bars and a field of bars with upper needles, each thus forming a caterpillar which controls the ribbon formed of textile fibers, before stretching by stretching cylinders.

Les systèmes d'étirage du type gills à chaînes sont, d'une manière générale, constitués d'un champ aiguillé inférieur et d'un champ aiguillé supérieur, chaque champ étant sous la forme de deux chaînes sans fin qui portent et entraînent des barrettes à aiguilles. Ces systèmes d'étirage sont conçus pour travailler les laines et les fibres lon­gues, et pour tourner à grandes vitesses. Ceci peut entraî­ner, dans certains cas, en fonction des matières travail­lées, des vitesses de marche, de la température et de l'hu­midité ambiantes, et encore en fonction d'éventuels autres paramètres, que des fibres ne quittent pas les aiguilles, restent accrochées à la sortie du système de contrôle, et s'enroulent autour de la chenille. De plus, lorsque quelques fibres se sont mises autour de la chenille, très rapidement de nombreuses autres suivent et forment un enroulement, ce qui cause en général d'importants dégâts aux chaînes, aux barrettes et aux aiguilles, lorsque l'enroulement n'est pas décelé en temps utile.Chain gill type stretching systems generally consist of a lower needle field and an upper needle field, each field being in the form of two endless chains which carry and drive bars with needles. These drawing systems are designed to work wool and long fibers, and to turn at high speeds. This can cause, in certain cases, depending on the materials worked, walking speeds, ambient temperature and humidity, and also depending on possible other parameters, that fibers do not leave the needles, remain attached at the exit of the control system, and wrap around the track. In addition, when a few fibers are put around the track, very quickly many others follow and form a winding, which generally causes significant damage to chains, bars and needles, when the winding is not not detected in good time.

Actuellement, pour éviter que les fibres ne for­ment un enroulement, certains dispositif ont déjà été imagi­nés.Currently, to prevent the fibers from forming a winding, certain devices have already been devised.

On a tout d'abord pensé à placer des brosses à l'endroit précis où les aiguilles viennent de quitter la matière, afin de nettoyer en permanence les aiguilles et d'intercepter toutes les fibres qui auraient pu éventuelle­ment être à l'origine d'un enroulement. Toutefois, ces brosses doivent être nettoyées régulièrement, ce qui demande des arrêts fréquents de la machine et entraîne ainsi une nette diminution de la production. De plus, des paquets de fibres se détachent et partent dans le ruban sortant, lors­que ces brosses sont surchargées de fibres, ce qui est pré­judiciable au ruban produit.We first thought of placing brushes at the precise place where the needles have just left the material, in order to permanently clean the needles and to intercept all the fibers which could possibly have been the cause of a winding. However, these brushes must be cleaned regularly, which requires frequent machine stops and thus results in a marked reduction in production. In addition, bundles of fibers detach and leave in the outgoing ribbon, when these brushes are overloaded with fibers, which is detrimental to the ribbon produced.

On a également pensé par la suite à disposer des raclettes, en caoutchouc naturel ou synthétique, qui raclent ou lèchent les aiguilles lorsqu'elles viennent de quitter le ruban formé de fibres textiles, de manière à réintroduire directement dans le ruban les fibres qui veulent s'en échap­per pour former un enroulement. Mais ces raclettes s'usent très rapidement, de sorte qu'elles ne remplissent leur fonc­tion que relativement peu de temps avant de devoir être rem­placées.We also thought later to have scrapers, natural or synthetic rubber, which scrape or lick the needles when they have just left the ribbon formed of textile fibers, so as to reintroduce directly into the ribbon the fibers which want to '' escape to form a winding. However, these squeegees wear out very quickly, so that they only perform their function relatively quickly before needing to be replaced.

Le problème général a résoudre par l'objet de la présente invention est donc de réaliser un dispositif de nettoyage assurant le maintien de la propreté des aiguilles des champs de barrettes à aiguilles d'un système d'étirage pour laines et fibres longues, dans lequel, il n'est plus nécessaire d'installer ni brosses, ni raclettes, ce qui évi­te, d'une part, l'achat de ces pièces et, d'autre part, leur installation sur des supports spéciaux qui sont également onéreux. Ceci implique egalement qu'il n'y a plus de brosses ou de raclettes à nettoyer régulièrement, de nombreux arrêts du système d'étirage et de nombreuses interventions étant ainsi évités, ce qui améliore le rendement et baisse, bien entendu, le prix de revient du produit sortant. Les pièces d'usure sont ainsi également supprimées, le nettoyage des chenilles, barrettes et aiguilles devant se faire d'une ma­nière permanente et continue.The general problem to be solved by the object of the present invention is therefore to produce a cleaning device ensuring that the needles are kept clean in the fields of needle bars of a drawing system for wools and long fibers, in which , it is no longer necessary to install either brushes or squeegees, which avoids, on the one hand, the purchase of these parts and, on the other hand, their installation on special supports which are also expensive. This also implies that there are no longer any brushes or squeegees to be cleaned regularly, many stops of the drawing system and numerous interventions being thus avoided, which improves the yield and lowers, of course, the price of returns from the outgoing product. The wearing parts are thus also eliminated, the cleaning of the tracks, bars and needles having to be done in a permanent and continuous manner.

En outre, les amas et les paquets de fibres qui de temps en temps partent dans le ruban, doivent être supprimés afin de garantir la qualité et la propreté du produit fini.In addition, the clumps and bundles of fibers which from time to time leave in the ribbon, must be removed in order to guarantee the quality and cleanliness of the finished product.

De meme, toutes les fibres volantes et impuretés doivent être constamment éloignées du ruban et éliminées, afin que la zone d'étirage et toute la tête de la machine soient toujours très propres, ceci augmentant les performances et la durée de vie de la machine et améliorant les caractéristiques du produit sortant. De même, le person­nel ne doit plus souffrir de la présence des fibres volan­tes.Likewise, all loose fibers and impurities must be constantly removed from the tape and removed, so that the drawing area and the entire machine head are always very clean, increasing the performance and service life of the machine and improving the characteristics of the outgoing product. Likewise, staff should no longer suffer from the presence of flying fibers.

Enfin, toutes les fibres volantes et celles qui pourraient rester accrochées aux aiguilles lorsque ces der­nières quittent le ruban, étant éliminées, il ne peut plus se former d'amorce d'enroulement et ainsi d'enroulement, ce qui évite tous les dégats que peut causer un enroulement, notamment la déformation ou même la casse des aiguilles, des barrettes ou des chenilles.Finally, all the flying fibers and those which could remain attached to the needles when the latter leave the ribbon, being eliminated, it can no longer form a winding primer and thus winding, which avoids all the damage that can cause winding, including deformation or even breakage of needles, barrettes or tracks.

A cet effet, le dispositif de nettoyage permanent conforme à l'invention est sous la forme d un moyen de souf­flage d'air sous pression, de l'intérieur de chaque chenille vers l'extérieur, sur la partie de chaque chenille recevant les barrettes venant de quitter le ruban appelé par les cy­lindres étireurs.To this end, the permanent cleaning device according to the invention is in the form of a means for blowing air under pressure, from the inside of each track towards the outside, on the part of each track receiving the bars. just leaving the ribbon called by the stretching cylinders.

L invention sera mieux comprise grâce à la des­cription ci-après d'un mode de réalisation préféré, donné à titre d'exemple non limitatif, et expliqué avec référence au dessin schématique annexé, dont la figure unique est une vue, en coupe, d'un système d'étirage à aiguilles pour fi­bres textiles longues, dont la partie de controle constituée par les aiguilles est munie du dispositif de nettoyage con­forme à l'invention.The invention will be better understood thanks to the description below of a preferred embodiment, given by way of nonlimiting example, and explained with reference to the appended schematic drawing, the single figure of which is a view, in section, of 'A needle stretching system for long textile fibers, the control part of which is made up of the needles is provided with the cleaning device according to the invention.

Selon l'invention, le dispositif de nettoyage per­manent consiste en un moyen 1, 1′ de soufflage d'air sous pression, de l'intérieur de chaque chenille 2, 2′ vers l'ex­térieur, sur la partie 7, 7′ de chaque chenille 2, 2′ rece­vant les barrettes 3, 3′ venant de quitter le ruban 4 appelé par les cylindres des etireurs 5.According to the invention, the permanent cleaning device consists of a means 1, 1 ′ for blowing air under pressure, from the inside of each track 2, 2 ′ towards the outside, on the part 7, 7 ′ of each track 2, 2 ′ receiving the bars 3, 3 ′ having just left the strip 4 called by the cylinders of the stretchers 5.

Conformément à une caractéristique de l'invention, le moyen 1, 1′ est sous la forme d'au moins un tube de souf­flage en corps creux, pourvu d'un ou plusieurs orifices 6 et alimenté en air sous pression.According to a characteristic of the invention, the means 1, 1 ′ is in the form of at least one blowing tube in a hollow body, provided with one or more orifices 6 and supplied with air under pressure.

Selon un mode de réalisation préférentiel de l'in­vention, et comme le montre la figure 1, le dispositif de nettoyage sera constitué par deux tubes 1, 1′ disposés à l'intérieur de l'espace 8, 8′ délimité par chaque chenille 2, 2′, en face de la partie 7, 7′ de chaque chenille 2, 2′, et parallèlement aux barrettes 3, 3′, la longueur de chaque tube 1, 1′ étant au moins égale à celle des barrettes 3, 3′.According to a preferred embodiment of the invention, and as shown in FIG. 1, the cleaning device will consist of two tubes 1, 1 ′ arranged at inside the space 8, 8 ′ delimited by each track 2, 2 ′, opposite the part 7, 7 ′ of each track 2, 2 ′, and parallel to the bars 3, 3 ′, the length of each tube 1, 1 ′ being at least equal to that of the bars 3, 3 ′.

Le tube 1 est avantageusement disposé à l'extrémi­té inférieure de la partie 7 de la chenille 2, et le tube 1′ est avantageusement disposé à l'extrémité supérieure de la partie 7′ de la chenille 2′, de manière à ce qu'une partie de l'air soufflé longe les corps des barrettes 3, 3′ par l'intérieur des chenilles 2, 2′ suivant les flèches 14, et s'échappe à la hauteur des dernières barrettes 3, 3′ venant de quitter le ruban 4, et à ce que l'autre partie de l'air s'échappe entre les barrettes 3, 3′ suivant les flèches 9 en lèchant les aiguilles 10, 10′ des barrettes 3, 3′ .The tube 1 is advantageously placed at the lower end of the part 7 of the track 2, and the tube 1 ′ is advantageously placed at the upper end of the part 7 ′ of the track 2 ′, so that part of the blown air runs along the bodies of the bars 3, 3 ′ through the inside of the tracks 2, 2 ′ according to the arrows 14, and escapes at the height of the last bars 3, 3 ′ having just left the ribbon 4, and that the other part of the air escapes between the bars 3, 3 ′ according to the arrows 9 by licking the needles 10, 10 ′ of the bars 3, 3 ′.

Toutefois, suivant une autre caractéristique de l'invention, les tubes 1, 1′ peuvent être disposés à n'im­porte quel point des parties 7, 7′ des chenilles 2, 2′However, according to another characteristic of the invention, the tubes 1, 1 ′ can be arranged at any point on the parts 7, 7 ′ of the tracks 2, 2 ′

Deux aspirations 11, 11′ sont prévues pour repren­dre la partie de l'air qui s'échappe entre les barrettes 3, 3′ suivant les flèches 9, l'une 11 située en dessous de la partie 7 de la chenille 2 et l'autre 11′ située au-dessus de la partie 7′ de la chenille 2′, de manière à évacuer les fibres et les impuretés qui ont été enlevées des barrettes 3, 3′ et des aiguilles 10, 10′ .Two aspirations 11, 11 ′ are provided to take up the part of the air which escapes between the bars 3, 3 ′ according to the arrows 9, one 11 located below the part 7 of the track 2 and the another 11 ′ located above the part 7 ′ of the track 2 ′, so as to evacuate the fibers and the impurities which have been removed from the bars 3, 3 ′ and the needles 10, 10 ′.

Le soufflage d'air à l'intérieur de chaque chenil­le 2, 2′ permet, par conséquent, d'éviter que les fibres qui quittent le ruban 4 restent accrochées aux aiguilles 10, 10′ des barrettes 3, 3′ qui viennent de quitter le ruban 4, em­pêchant ainsi par là même la formation des enroulements ou des fibres volantes préjudiciables.The blowing of air inside each track 2, 2 ′ therefore makes it possible to prevent the fibers leaving the ribbon 4 from becoming attached to the needles 10, 10 ′ of the strips 3, 3 ′ which have just left the tape 4, thereby preventing the formation of harmful windings or flying fibers.

L'air soufflé est également guidé par des tôles 3, 13′ situées de part et d'autre de chaque tube 1, 1 , ces tubes étant fixés à ces tôles 13, 13′ par tous moyens con­nus, par exemple, par soudure.The supply air is also guided by sheets 3, 13 ′ located on either side of each tube 1, 1, these tubes being fixed to these sheets 13, 13 ′ by any known means, for example, by welding.

Selon une première variante de l'invention, chaque tube 1, 1′ comporte plusieurs orifices 6 sous la forme de trous, le nombre de trous étant avantageusement comprisent re 10 et 20, ces trous 6 étant, de préférence, alignés et disposés sur la partie du tube 1, 1′ faisant directement fa­ce aux barrettes 3, 3′ .
Chaque orifice 6 peut avantageusement présenter une section circulaire.According to a first variant of the invention, each tube 1, 1 ′ has several orifices 6 in the form of holes, the number of holes being advantageously understood to be 10 and 20, these holes 6 preferably being aligned and arranged on the part of the tube 1, 1 ′ directly facing the bars 3, 3 ′.
Each orifice 6 can advantageously have a circular section.

Selon une seconde variante de l'invention, chaque tube 1, 1′ comporte un ou plusieurs orifices 6 sous la forme d'une ou plusieurs fentes situées sur toute la longueur du tube 1, 1′, permettant la diffusion de l'air comprimé en un ou plusieurs jets plats, et disposées sur la partie du tube 1, 1′ faisant directement face aux barrettes 3, 3′ .According to a second variant of the invention, each tube 1, 1 ′ has one or more orifices 6 in the form of one or more slots located over the entire length of the tube 1, 1 ′, allowing the diffusion of compressed air in one or more flat jets, and arranged on the part of the tube 1, 1 ′ directly facing the bars 3, 3 ′.

Enfin, selon une dernière caractéristique de l'in­vention, chaque tube 1, 1′ est muni d'un orifice 12 d'arri­vée d'air sous pression provenant soit d'un réseau d'air comprimé, soit de toute autre source d'air, telle qu'une pompe à air, la pression d'injection dans les tubes 1, 1' étant comprise, de préférence, entre 0,5 et 1,5 bars, avantageusement 1 bar.Finally, according to a last characteristic of the invention, each tube 1, 1 ′ is provided with an orifice 12 for the arrival of pressurized air coming either from a compressed air network or from any other source of air, such as an air pump, the injection pressure in the tubes 1, 1 'being preferably between 0.5 and 1.5 bars, advantageously 1 bar.

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 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.
