Description

La présente invention concerne le domaine de l'industrie textile, en particulier le traitement par lavage et/ou par teinture des fils et a pour objet un dispositif d'exprimage sur fils.The present invention relates to the field of the textile industry, in particularly the treatment by washing and / or dyeing of the threads and has for object wire expressing device.

Les fils textiles subissent généralement, avant leur utilisation, notamment pour le tissage, des traitements de lavage et/ou de blanchissage ainsi que de teinture. Ces différents traitements sont effectués par voie humide, ayant pour conséquence un excédent d'humidité de l'ordre de 100 % à 150 % en poids, et nécessitent une opération de séchage consécutive.Textile threads generally undergo, before their use, especially for weaving, washing and / or bleaching treatments as well than dye. These various treatments are carried out wet, having as a consequence an excess of humidity of the order of 100% to 150% by weight, and require a subsequent drying operation.

Actuellement, l'opération de séchage est réalisée par apport d'énergie sous forme de chaleur et/ou d'un courant d'air réalisant une évaporation de l'excédent d'humidité. Un tel séchage entraíne une consommation très élevée d'énergie et, de ce fait, un coût de production élevé.Currently, the drying operation is carried out using energy in the form of heat and / or a stream of air evaporation of excess moisture. Such drying results in very high consumption energy and therefore a high production cost.

Il est également connu de réaliser un essorage mécanique, notamment d'écheveaux ou de bobines, au moyen de dispositifs centrifuges. Dans un tel cas, une humidité résiduelle de 50 % peut être obtenue très rapidement avec une dépense énergétique très faible. Cependant, ces procédés d'essorage ne sont pas exploitables dans le cadre d'un traitement en continu de fils, c'est-à-dire lorsque les fils sont en défilement et sont disposés en nappes.It is also known to carry out a mechanical spin, in particular hanks or coils, by means of centrifugal devices. In in such a case, a residual humidity of 50% can be obtained very quickly with very low energy expenditure. However, these spinning processes are not not usable in the context of continuous wire processing, i.e. when the threads are running and are arranged in layers.

Enfin, on connaít également un procédé d'exprimage de l'excédent d'humidité par une surpression d'air voir par exemple GB-A-2009030 et FR-A-2575770. Un tel exprimage permet des gains comparables à ceux obtenus par essorage mécanique. Cependant, dans le cas du traitement de fils en nappes, un tel procédé d'exprimage n'est pas adapté, les fils n'étant pas soutenus lors du traitement par jet d'air et risquant d'être emmêlés sous l'effet dudit jet.Finally, we also know a process for expressing the surplus humidity by an air overpressure see for example GB-A-2009030 and FR-A-2575770. Such an expression allows gains comparable to those obtained by mechanical spinning. However, in the case of treatment of ply yarns, such an expressing method is not suitable, the yarns are not supported during the air jet treatment and may be tangled under the effect of said throw.

La présente invention a pour but de pallier les inconvénients des dispositifs d'exprimage connus à ce jour en proposant un dispositif d'exprimage sur fils adapté au traitement d'une nappe de fils, permettant un exprimage optimal de chaque fil de la nappe et une mise en place aisée des fils de la nappe dans ledit dispositif.The object of the present invention is to overcome the drawbacks of the expression devices known to date by providing an expression device on threads suitable for treating a sheet of threads, allowing optimal expression of each ply yarn and easy placement of the ply yarns in said device.

A cet effet, le dispositif d'exprimage des fils d'une nappe de fils est caractérisé en ce qu'il est essentiellement constitué par un peigne de guidage et d'exprimage des fils individuels d'une nappe de fils et par un moyen de soufflage d'air comprimé au droit de chaque intervalle entre deux dents dudit peigne, ce moyen de soufflage d'air coopérant avec le peigne pour réaliser l'exprimage de l'excédent d'humidité. To this end, the device for expressing the threads of a layer of threads is characterized in that it consists essentially of a comb for guiding and expressing the wires individual plies of yarn and by means of blowing compressed air to the right of each interval between two teeth of said comb, this blowing means air cooperating with the comb to express the excess moisture.

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'un dispositif conforme à l'invention ;
  • la figure 2 est une vue en élévation frontale et en coupe d'un dispositif suivant la figure 1 et,
  • la figure 3 est une vue partielle en coupe et à plus grande échelle d'une variante de réalisation du peigne de guidage et d'exprimage.
    • 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 device according to the invention;
  • FIG. 2 is a front elevation view in section of a device according to FIG. 1 and,
  • Figure 3 is a partial sectional view on a larger scale of an alternative embodiment of the guide and expression comb.

    • Conformément à l'invention, et comme le montrent plus particulièrement, à titre d'exemple, les figures 1 et 2 des dessins annexés, le dispositif d'exprimage sur fils est essentiellement constitué par un peigne 1 de guidage et d'exprimage des fils individuels d'une nappe de fils et par un moyen 2 de soufflage d'air comprimé au droit de chaque intervalle entre deux dents 3 dudit peigne 1, ce moyen de soufflage d'air 2 coopérant avec le peigne 1 pour réaliser l'exprimage de l'excédent d'humidité.In accordance with the invention, and as shown more particularly, by way of example, Figures 1 and 2 of the accompanying drawings, the wire expressing device essentially consists of a comb 1 of guiding and expressing individual yarns from a web of yarns and by means 2 of compressed air blowing at the right of each interval between two teeth 3 of said comb 1, this air blowing means 2 cooperating with the comb 1 to produce expressing excess moisture.

    Le peigne 1 est préférentiellement constitué par un assemblage de dents 3 et d'entretoises 4 disposées entre lesdites dents 3 et par au moins une broche 5 de serrage desdites dents 3 et entretoises 4 sur un support 6 (figures 1 et 2). Une telle constitution du peigne 1 permet une adaptation aisée de celui-ci à une quantité prédéterminée de fils d'une nappe, par simple démontage de la ou des broches 5 du support 6 et montage ou démontage du nombre de paires de dent et entretoise nécessaire, puis remontage des broches 5 nouvellement équipées sur le support 6.The comb 1 is preferably constituted by an assembly of teeth 3 and spacers 4 disposed between said teeth 3 and by at least one pin 5 for clamping said teeth 3 and spacers 4 on a support 6 (Figures 1 and 2). Such a constitution of the comb 1 allows an easy adaptation thereof to a predetermined quantity of yarns of a sheet, by simple disassembly of the one or more pins 5 of the support 6 and mounting or dismounting the number of pairs of teeth and spacer required, then reassembly of the newly fitted pins 5 on the support 6.

    Les dents 3 se présentent avantageusement sous forme de plaquettes minces, dont la section plane dépasse largement celle des entretoises 4. Une telle réalisation des dents 3 et des entretoises 4 permet un guidage précis de chaque fil entre deux dents 3 successives et l'exprimage de l'humidité de manière indépendante d'un fil à l'autre, c'est-à-dire sans que lesdits fils puissent entrer en contact avant et pendant ledit exprimage.The teeth 3 are advantageously in the form of platelets thin, whose planar section greatly exceeds that of the spacers 4. Such a production of teeth 3 and spacers 4 allows precise guidance of each wire between two successive teeth 3 and the expression of humidity so independent from one wire to another, that is to say without said wires being able to enter contact before and during said expression.

    Les entretoises 4, qui sont interchangeables, présentent des épaisseurs variables en fonction du numéro métrique des fils à traiter. Ainsi, suivant le numéro métrique ou le diamètre des fils, le peigne 1 est entièrement démonté et des entretoises 4 adaptées audit numéro métrique sont montées sur les broches 5 entre les plaquettes formant les dents 3, l'ensemble étant serré sur le support 6. Il en résulte que les fils d'une nappe sont toujours guidés d'une manière optimale entre les dents 3. The spacers 4, which are interchangeable, have variable thicknesses depending on the metric number of the wires to be treated. So, depending on the metric number or the diameter of the wires, comb 1 is entirely disassembled and spacers 4 adapted to said metric number are mounted on the pins 5 between the plates forming the teeth 3, the assembly being tightened on the support 6. As a result, the threads of a sheet are always guided in a way optimal between teeth 3.

    Le dispositif est complété, en outre, par un cylindre 7 de détournement de la nappe de fils s'étendant, en position de service, au moins partiellement sous le niveau des entretoises 4 du peigne 1 (figure 1), de manière à appliquer les fils de la nappe obliquement contre l'arête correspondante des entretoises 4. Ainsi, par l'effet de frottement des fils contre l'arête des entretoises 4 et, du fait de la tension de la nappe de fils en défilement, on obtient un exprimage important d'humidité dû à un écrasement relatif des fils sur les entretoises 4.The device is completed, in addition, by a cylinder 7 of diversion of the ply of wires extending, in the service position, at least partially below the level of the spacers 4 of the comb 1 (FIG. 1), so as to apply the threads of the tablecloth obliquely against the corresponding edge of the spacers 4. Thus, by the friction effect of the wires against the edge of the spacers 4 and, due to the tension of the traveling web of wires, an expression is obtained high humidity due to relative crushing of the wires on the spacers 4.

    Afin d'éviter une détérioration des fils lors de l'opération d'exprimage, les entretoises 4 présentent avantageusement, vues à partir de l'entrée des fils dans le peignes 1, un chanfrein 8 ou un arrondi. Ainsi, les fils de la nappe qui sont détournés par le cylindre 7 sont appliqués avec une pression prédéterminée contre le chanfrein 8 ou l'arrondi des entretoises 4 et, sous l'effet de la pression résultant de l'application par le cylindre 7 et de la traction sur les fils, on obtient un exprimage mécanique important de l'humidité hors du fil.To avoid damage to the wires during the operation Expression, the spacers 4 advantageously have, seen from the entrance wires in the combs 1, a chamfer 8 or a rounding. So the threads of the tablecloth which are diverted by cylinder 7 are applied with pressure predetermined against the chamfer 8 or the rounding of the spacers 4 and, under the effect of the pressure resulting from the application by the cylinder 7 and from the traction on the wires, a significant mechanical expression of the humidity is obtained outside the wire.

    Le moyen de soufflage d'air 2 se présente sous forme d'une buse 9 allongée, s'étendant parallèlement au-dessus du peigne 1 et délivrant un jet plat à travers une fente 10, ladite buse 9 étant raccordée à un moyen d'alimentation en air comprimé par l'intermédiaire d'un raccord 11.The air blowing means 2 is in the form of a nozzle 9 elongated, extending parallel above the comb 1 and delivering a flat jet to through a slot 10, said nozzle 9 being connected to an air supply means compressed via a connector 11.

    Selon une variante de réalisation de l'invention, non représentée aux dessins annexés, le moyen de soufflage d'air 2 peut également se présenter sous forme d'une buse à jets cylindriques parallèles, dont les trous de soufflage d'air présentent un diamètre correspondant à celui des fils à exprimer.According to an alternative embodiment of the invention, not shown in attached drawings, the air blowing means 2 can also be presented under form of a nozzle with parallel cylindrical jets, the air blowing holes of which have a diameter corresponding to that of the wires to be expressed.

    Selon une autre caractéristique de l'invention, la buse 9 est avantageusement montée de manière pivotante sur le support 6 du peigne 1 par l'intermédiaire d'un levier 12, le raccord 11 du moyen d'alimentation étant sous forme d'un raccord tournant étanche, dont l'axe de rotation est aligné avec celui du levier 12. Un tel mode de réalisation permet, comme le montre la figure 1 des dessins annexés, en trait mixte fin, un pivotement du levier 12 avec la buse 9 hors de sa zone de coopération avec le peigne 1, de manière à favoriser la mise en place des fils entre les dents 3 du peigne 1.According to another characteristic of the invention, the nozzle 9 is advantageously pivotally mounted on the support 6 of the comb 1 by via a lever 12, the connection 11 of the supply means being under form of a tight rotary coupling, the axis of rotation of which is aligned with that of the lever 12. Such an embodiment allows, as shown in FIG. 1, attached drawings, in thin dashed line, a pivoting of the lever 12 with the nozzle 9 out of its zone of cooperation with the comb 1, so as to favor the establishment wires between the teeth 3 of the comb 1.

    A cet effet, selon une autre caractéristique de l'invention, le cylindre de détournement 7 est également monté sur un levier pivotant 13, dont l'axe de pivotement est aligné avec celui du levier 12 de support de la buse 9.To this end, according to another characteristic of the invention, the cylinder diversion 7 is also mounted on a pivoting lever 13, the axis of which pivot is aligned with that of the lever 12 for supporting the nozzle 9.

    Le levier 12 de support de la buse 9 et le levier 13 de support du cylindre de détournement 7 sont préférentiellement montés sur un palier de pivotement commun 14 (figure 1). The lever 12 for supporting the nozzle 9 and the lever 13 for supporting the diversion cylinder 7 are preferably mounted on a bearing of common pivot 14 (Figure 1).

    Selon une autre caractéristique de l'invention, les plaquettes formant les dents 3 du peigne 1 présentent, sur leur côté tourné vers la buse 9, en position de service de cette dernière, une découpe 15 correspondant sensiblement à la section de ladite buse 9 (figure 1). Ainsi, la buse 9 peut être basculée en position de service à une distance des entretoises 4 du peigne 1 très faible et limitée par la découpe 15 des plaquettes formant les dents 3.According to another characteristic of the invention, the plates forming the teeth 3 of the comb 1 have, on their side facing the nozzle 9, in position service of the latter, a cutout 15 corresponding substantially to the section of said nozzle 9 (FIG. 1). Thus, the nozzle 9 can be tilted in position service at a distance from the spacers 4 of the comb 1 very small and limited by the cutting 15 of the plates forming the teeth 3.

    Lorsque la buse 9 est ainsi en butée contre les dents 3, sa fente de soufflage 10 se trouve à très faible distance au-dessus des fils de la nappe de fils dont l'exprimage doit être réalisé et délivre un jet d'air en direction de l'entrée des fils dans les dents 3 du peigne 1 et propulse l'humidité présente dans ces derniers et/ou déjà partiellement exprimée sur le chanfrein 8 ou arrondi des entretoises 4, à travers les dents 3 dans l'espace situé sous le support 6.When the nozzle 9 is thus in abutment against the teeth 3, its slot of blowing 10 is located a very short distance above the son of the son ply whose expression must be carried out and delivers a jet of air towards the entry of wires in teeth 3 of comb 1 and propels the moisture present in them and / or already partially expressed on the chamfer 8 or rounded spacers 4, to through the teeth 3 in the space under the support 6.

    Selon une caractéristique de l'invention, et comme le montre la figure 1 des dessins annexés, la buse 9 est montée sur son levier de support pivotable 12 de manière réglable en rotation autour de son axe longitudinal, avec possibilité de blocage en position par l'intermédiaire d'une vis 16 coopérant avec une rainure oblongue 17 traversant un flasque 18 solidaire de l'extrémité correspondante de la buse 9. Ainsi, la fente de soufflage 10 de la buse 9 peut être réglée en direction du chanfrein ou arrondi 8, de manière optimale, par simple rotation de la buse 9, puis blocage en position de celle-ci par serrage du flasque 18 sur le levier 12 au moyen de la vis 16.According to a characteristic of the invention, and as shown in the Figure 1 of the accompanying drawings, the nozzle 9 is mounted on its support lever pivotable 12 in an adjustable manner in rotation about its longitudinal axis, with possibility of locking in position by means of a screw 16 cooperating with an oblong groove 17 passing through a flange 18 secured to the end nozzle 9. Thus, the blowing slot 10 of the nozzle 9 can be adjusted in the direction of the chamfer or rounded 8, optimally, by simple rotation of the nozzle 9, then locking in position thereof by tightening the flange 18 on lever 12 by means of screw 16.

    Conformément à une autre caractéristique de l'invention, non représentée aux dessins annexés, la section de la fente de soufflage 10 peut être réglable mécaniquement par prévision de bords mobiles en écartement, au moyen de vis, notamment par déplacement oblique par rapport à l'axe de soufflage, ou encore par montage des bords de la fente sur des cales amovibles.According to another characteristic of the invention, not shown in the accompanying drawings, the section of the blowing slot 10 can be mechanically adjustable by providing movable edges in spacing, by means screws, in particular by oblique displacement relative to the blowing axis, or again by mounting the edges of the slot on removable shims.

    Un tel réglage de la section de la fente de soufflage 10 peut être particulièrement intéressant pour influer sur la vitesse du courant d'air de soufflage, à pression et à débit constants, et ainsi sur la capacité de transport optimal d'humidité par l'air.Such an adjustment of the cross section of the blowing slot 10 can be particularly interesting for influencing the speed of the air flow blowing, at constant pressure and flow, and thus on the transport capacity optimal air humidity.

    La figure 3 des dessins annexés représente partiellement et à plus grande échelle une variante de réalisation du peigne 1 dans laquelle les dents 3 sont de deux types, 3' - 3", présentant des hauteurs différentes et disposées en alternance.Figure 3 of the accompanying drawings partially and more large scale an alternative embodiment of the comb 1 in which the teeth 3 are of two types, 3 '- 3 ", with different heights and arranged in sandwich course.

    Comme il ressort plus particulièrement de la figure 3, une dent plus haute 3' est toujours précédée et suivie par une dent moins haute 3", de sorte que l'espacement entre les faces correspondantes de deux dents plus hautes 3' est agrandi et que pour la mise en place de deux fils entre ces deux dents plus hautes 3' et la dent intermédiaire plus basse 3", il suffit d'appuyer le premier fil contre la face interne de la première dent la plus haute 3' et de la descendre entre cette dent 3' et la dent plus basse 3" jusqu'au contact de l'entretoise 4, tandis que l'autre fil peut être plaqué contre la face interne correspondante de la deuxième dent plus haute 3", puis être descendu en contact avec l'entretoise 4 entre la dent plus basse 3" et la dent plus haute 3'. Ainsi, une mise en place sans risque d'erreur, en particulier d'interversion de fil, est grandement facilitée.As can be seen more particularly from FIG. 3, a tooth more high 3 'is always preceded and followed by a lower tooth 3 ", so that the spacing between the corresponding faces of two taller teeth 3 'is enlarged and that for the placement of two wires between these two teeth more high 3 'and lower intermediate tooth 3 ", just press the first wire against the internal face of the first highest tooth 3 'and to lower it between this tooth 3 'and the lower tooth 3 "until contact with the spacer 4, while the other wire can be pressed against the corresponding internal face of the second higher tooth 3 ", then be lowered in contact with the spacer 4 between the tooth lower 3 "and the higher tooth 3 '. Thus, an installation without risk of error, especially wire reversal, is greatly facilitated.

    Après mise en place de l'ensemble des fils sur le peigne 1, les leviers 12 et 13 peuvent être actionnés de manière à amener la buse 9 et le cylindre de détournement 7 en position de service représentée à la figure 1 des dessins annexés, et une opération d'exprimage en continu peut être démarrée simultanément à l'alimentation en air sous pression de la buse 9. Tous les fils passant dans le dispositif conforme à l'invention subissent un détour les appliquant sur les entretoises correspondantes 4 et ayant pour effet de réaliser un exprimage mécanique de leur humidité résiduelle, un exprimage complémentaire par jet d'air sous pression étant réalisé par l'air sous pression soufflé à travers la fente 10 de la buse 9 sur la partie avant des entretoises 4, l'air ainsi soufflé réalisant en outre le transport et l'évacuation de l'humidité ainsi exprimée hors du peigne 1 dans l'espace sous ce dernier et sous son support 6.After placing all the wires on comb 1, the levers 12 and 13 can be actuated so as to bring the nozzle 9 and the cylinder diversion 7 in the service position shown in Figure 1 of the drawings appended, and a continuous printing operation can be started simultaneously with the pressurized air supply to nozzle 9. All wires passing through the device according to the invention undergo a detour applying them on the corresponding spacers 4 and having the effect of producing an expression mechanical residual moisture, additional expression by air jet under pressure being produced by pressurized air blown through slot 10 of the nozzle 9 on the front part of the spacers 4, the air thus blown further providing the transport and evacuation of the humidity thus expressed out of the comb 1 in the space under the latter and under its support 6.

    Grâce à l'invention, il est possible de réaliser un exprimage important de l'humidité de fils lavés ou teints avec des gains comparables à ceux obtenus par essorage, ce sur des fils défilant en continu.Thanks to the invention, it is possible to achieve significant expression moisture from washed or dyed yarns with gains comparable to those obtained by spinning, on threads running continuously.

    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 are still possible, in particular from the point of view of the constitution of the various elements or by substitution of technical equivalents, without departing from the scope of protection of the invention.
