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 particular the treatment by washing and / or dyeing of threads and relates to an expression device on threads.

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.The textile yarns generally undergo, before their use, in particular for weaving, washing and / or bleaching treatments as well as dyeing. These various treatments are carried out wet, resulting in an excess of humidity of the order of 100% to 150% by weight, and require a consecutive 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 entraîne une consommation très élevée d'énergie et, de ce fait, un coût de production élevé.Currently, the drying operation is carried out by supplying energy in the form of heat and / or a stream of air producing evaporation of the excess moisture. Such drying results in a very high energy consumption 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 make a mechanical spin, in particular of skeins or coils, by means of centrifugal devices. In such a case, a residual humidity of 50% can be obtained very quickly with a very low energy expenditure. However, these spinning methods cannot be used in the context of a continuous treatment of threads, that is to say when the threads are running and are arranged in layers.

Enfin, on connaît également un procédé d'exprimage de l'excédent d'humidité par une surpression d'air. 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, there is also known a method of expressing excess moisture by an air pressure. Such an expression allows gains comparable to those obtained by mechanical spinning. However, in the case of the treatment of ply yarns, such a pressing process is not suitable, the yarns not being supported during the air jet treatment and risking being tangled under the effect of said jet.

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 proposing an expression device on threads adapted to the treatment of a sheet of threads, allowing optimal expression of each thread of the sheet and a easy implementation of the son of the web in said device.

A cet effet, le dispositif d'exprimage sur 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 wire-expressing device is characterized in that it is essentially constituted by a comb for guiding and expressing the individual wires from a layer of wires and by a means for blowing compressed air to the right of each interval between two teeth of said comb, this air blowing means cooperating with the comb to achieve the expression of 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, FIGS. 1 and 2 of the appended drawings, the device for expressing on wires essentially consists of a comb 1 for guiding and expressing the wires individual of a ply of son and by a means 2 for blowing compressed air 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 achieve the expression of 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 of the latter to a predetermined quantity of son of a ply, by simple disassembly of the pin (s) 5 of the support 6 and assembly or disassembly of 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 thin plates, the flat section of which largely exceeds that of the spacers 4. Such an embodiment of the teeth 3 and of the spacers 4 allows precise guidance of each wire between two successive teeth 3 and the expression of humidity independently from one thread to another, that is to say without said threads being able to come into 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 as a function of the metric number of the wires to be treated. Thus, according to the metric number or the diameter of the wires, the 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 ply are always guided in an optimal manner between the 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 for diverting 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 son of the web obliquely against the corresponding edge of the struts 4. Thus, by the friction effect of the wires against the edge of the struts 4 and, due to the tension of the web of threads in movement, 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.In order to avoid deterioration of the wires during the pressing operation, the spacers 4 advantageously have, seen from the entry of the wires into the combs 1, a chamfer 8 or a rounding. Thus, the wires of the ply which are diverted by the cylinder 7 are applied with a predetermined pressure 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 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 an elongated nozzle 9, extending in parallel above the comb 1 and delivering a flat jet through a slot 10, said nozzle 9 being connected to a means of compressed air supply 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 the accompanying drawings, the air blowing means 2 can also be in the 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 means of a lever 12, the connector 11 of the supply means being in the form of a connector tight turning, whose axis of rotation is aligned with that of the lever 12. Such an embodiment allows, as shown in Figure 1 of the accompanying drawings, in thin dashed line, pivoting of the lever 12 with the nozzle 9 out of its area of cooperation with the comb 1, so as to favor the positioning of the 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 diversion cylinder 7 is also mounted on a pivoting lever 13, the pivot axis of which 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 common pivot bearing 14 (FIG. 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 the service position of the latter, a cutout 15 corresponding substantially to the section of said nozzle 9 ( figure 1). Thus, the nozzle 9 can be tilted into the operating position at a distance from the spacers 4 of the comb 1 which is very small and limited by the cutout 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 blowing slot 10 is located a very short distance above the threads of the ply of threads the expression of which must be achieved and delivers a jet of air in the direction of the entry of the wires into the teeth 3 of the comb 1 and propels the moisture present in the latter and / or already partially expressed on the chamfer 8 or rounded of the spacers 4, through the teeth 3 in the space located 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 Figure 1 of the accompanying drawings, the nozzle 9 is mounted on its pivotable support lever 12 so as to be adjustable in rotation about its longitudinal axis, with the possibility of locking in position by the intermediate of a screw 16 cooperating with an oblong groove 17 passing through a flange 18 integral with the corresponding end of the 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 of the latter by tightening the flange 18 on the lever 12 by means of the 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.In accordance with 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 separation, by means of screws, in particular by oblique displacement relative to the blowing axis, or 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 may be particularly advantageous in order to influence the speed of the blowing air stream, at constant pressure and flow, and thus the optimum moisture transport capacity by the air.

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 shows partially and on a larger scale an alternative embodiment of the comb 1 in which the teeth 3 are of two types, 3 '- 3 ", having different heights and arranged alternately.

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 taller tooth 3 'is always preceded and followed by a shorter one 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 higher teeth 3 'and the lower intermediate tooth 3 ", it suffices to 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 into contact with the spacer 4 between the lower tooth 3 "and the higher tooth 3 '. Thus, installation without risk of error, in particular of 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 the assembly of the set of wires on the comb 1, the levers 12 and 13 can be actuated so as to bring the nozzle 9 and the diversion cylinder 7 into the service position shown in FIG. 1 of the accompanying drawings, and a continuous pressing operation can be started simultaneously with the supply of pressurized air to the nozzle 9. All the wires passing through the device according to the invention undergo a detour applying them to the corresponding spacers 4 and having the effect to carry out a mechanical expression of their residual humidity, an additional expression by pressurized air jet being carried out by the pressurized air blown through the slot 10 of the nozzle 9 on the front part of the spacers 4, the air thus blown additionally carrying out and evacuating the moisture thus expressed out of the comb 1 into 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 a significant expression of the moisture of washed or dyed yarns with gains comparable to those obtained by spinning, this on yarns 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 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.
