Description

MACHINE PERFECTIONNEE PERMETTANT D'EFFECTUER. EN CONTINU. LE RETORDAGE OU LE CABLAGE DE FILS SUIVI D'UN TRAITEMENT THERMIQUE COMPLEMENTAIRE. IMPROVED MACHINE FOR PERFORMING. CONTINUOUSLY. TWISTING OR WIRING OF WIRES FOLLOWED BY AN ADDITIONAL HEAT TREATMENT.
La présente invention concerne une machine perfectionnée permettant d'effectuer, en continu, le retordage ou le câblage de fils suivi d'un traitement thermique complémentaire.The present invention relates to an improved machine making it possible to continuously twist or wire wires followed by additional heat treatment.
De telles machines utilisées notamment pour la réalisation de fils pour tapis, ont été proposées depuis fort longtemps comme cela ressort notamment du FR-A-1 455 499 et de l'US-A-3 525 205. Il a également été proposé d'utiliser de telles machines pour traiter des fils synthétiques partiellement étirés, l'étirage étant réalisé au niveau de la broche double torsion comme cela ressort de l'US-A-2 414 568.Such machines used in particular for making yarns for carpets have been proposed for a very long time, as is apparent in particular from FR-A-1 455 499 and from US-A-3 525 205. It has also been proposed to using such machines to process partially drawn synthetic yarns, the drawing being carried out at the level of the double twist spindle as shown in US-A-2 414 568.
Ainsi que cela ressort de ces documents, de telles installations sont constituées par un bâti central qui supporte une pluralité de positions de travail identiques comprenant, si l'on considère le sens de passage du fil :As is apparent from these documents, such installations are constituted by a central frame which supports a plurality of identical working positions comprising, if one considers the direction of passage of the wire:
- une broche simple ou double torsion supportant un enroulement de fil,- a single or double twist spindle supporting a wire winding,
- des moyens d'appel du fil,- means of calling the wire,
- un four de traitement thermique disposé soit verticalement (FR 1 455 499), soit horizontalement (US-A-3 525 205), suivi d'une zone de refroidissement et ; . des moyens de renvidage du fil traité.- a heat treatment oven arranged either vertically (FR 1 455 499) or horizontally (US-A-3 525 205), followed by a cooling zone and; . means for winding the treated yarn.
Dans de telles installations, le fil est maintenu à l'état relaxé pendant le traitement thermique et pendant la phase de refroidissement avant bobinage. Si les machines faisant l'objet des brevets précités portent sur le retordage d'un fil simple, il a été proposé depuis fort longtemps d'utiliser des machines similaires pour réaliser des opérations de câblage direct comme cela ressort de l'US-A-3 820 316. Pour ce faire, dans un tel cas, le fil provenant de l'enroulement monté sur la broche est associé à un second fil provenant d'une seconde bobine montée fixe sur le bâti de la machine, et qui est amené, au travers du fût de ladite broche, jusqu'à une tête de câblage disposée dans le prolongement de cette dernière.In such installations, the wire is kept in the relaxed state during the heat treatment and during the cooling phase before winding. If the machines covered by the aforementioned patents relate to the twisting of a single wire, it has long been proposed to use similar machines to carry out direct wiring operations as is apparent from US-A- 3 820 316. To do this, in such a case, the wire coming from the winding mounted on the spindle is associated with a second wire coming from a second coil mounted fixed on the frame of the machine, and which is brought, through the barrel of said pin, to a wiring head arranged in the extension of the latter.
Or on a trouvé, et c'est ce qui fait l'objet de la présente invention, un perfectionnement apporté à un tel type de machine qui permet d'améliorer la qualité des fils produits, notamment en ce qui a trait au toucher et à l'aspect que présente l'article, tapis par exemple, réalisé à partir de tels fils.However, we have found, and this is what is the subject of the present invention, an improvement made to such a type of machine which makes it possible to improve the quality of the wires produced, in particular as regards touch and the appearance of the article, carpet for example, made from such son.
D'une manière générale, la machine selon l'invention est du type comportant, d'une manière similaire aux enseignements de l'US-A-3 525 205, un bâti central supportant une pluralité de positions de travail identiques comprenant chacune :In general, the machine according to the invention is of the type comprising, in a manner similar to the teachings of US Pat. No. 3,525,205, a central frame supporting a plurality of identical working positions each comprising:
- une broche double torsion ou de câblage supportant un enroulement de fil, destiné à être tordu ou cable avec un second fil ;- a double twist or wiring spindle supporting a wire winding, intended to be twisted or cable with a second wire;
- des moyens d'appel du fil permettant d'annuler la tension qui résulte de l'opération de retordage ou câblage ;- means for calling up the wire making it possible to cancel the tension which results from the twisting or wiring operation;
- des moyens de chauffage du fil suivis d'une zone de refroidissement et ;- wire heating means followed by a cooling zone and;
- des moyens de renvidage du fil traité. La machine conforme à l'invention qui permet de réaliser aussi bien une opération de retordage qu'une opération de câblage direct, se caractérise en ce que :- means for winding the treated thread. The machine according to the invention, which makes it possible to carry out both a twisting operation and a direct wiring operation, is characterized in that:
- les moyens de chauffage sont constitués par un four rectiligne disposé verticalement ou sensiblement verticalement ;- The heating means are constituted by a rectilinear oven arranged vertically or substantially vertically;
- le fil effectue un aller-retour à l'intérieur dudit four et est introduit et extrait de ce dernier par sa partie basse, un système d'appel et de renvoi pour ledit fil étant prévu en partie supérieure ;- The wire goes back and forth inside said oven and is introduced and extracted from the latter by its lower part, a call and return system for said wire being provided in the upper part;
- des moyens sont prévus pour maintenir le fil sous une tension minimale pendant la phase de refroidissement et pour le délivrer aux moyens de renvidage.- Means are provided to maintain the wire under a minimum tension during the cooling phase and to deliver it to the winding means.
Grâce à une telle conception de machine, il est possible non seulement de doubler la durée de traitement thermique pour un four de longueur donnée, mais également de pouvoir maîtriser parfaitement les tensions communiquées au fil pendant les phases de traitement thermique et de refroidissement. Une telle possibilité est obtenue grâce à la présence du système d'appel prévu à la partie haute du four qui permet de donner une tension précise, constante, pendant la période de montée en température réalisée entre le délivreur d'entrée et ledit organe de renvoi et d'appel puis, de maintenir le fil à l'état complètement relaxé lors du second passage à l'intérieur du four ainsi que dans la zone de refroidissement.Thanks to such a machine design, it is possible not only to double the duration of heat treatment for an oven of given length, but also to be able to perfectly control the tensions communicated to the wire during the heat treatment and cooling phases. Such a possibility is obtained thanks to the presence of the call system provided at the upper part of the oven which makes it possible to give a precise, constant voltage, during the period of temperature rise carried out between the input deliverer and said return member. and then call, to maintain the wire in the fully relaxed state during the second pass inside the oven as well as in the cooling zone.
Selon une première forme de réalisation conforme à l'invention, après traitement thermique et avant renvidage, le fil est réceptionné sur un tapis de relaxation mobile où il forme une réserve, la vitesse de réception de l'ensemble de renvidage étant régulée pour que la quantité de fil mis en réserve soit maintenue entre deux valeurs minimale et maximale prédéterminées. Dans une autre forme de réalisation, le parcours refroidi du fil est réalisé par l'intermédiaire d'éléments rotatifs de guidage interposés entre le sortie du four et un tendeur positionné en amont et dans le plan de symétrie du système de renvidage.According to a first embodiment according to the invention, after heat treatment and before winding, the yarn is received on a mobile relaxation mat where it forms a reserve, the speed of reception of the winding assembly being regulated so that the quantity of wire placed in reserve is kept between two predetermined minimum and maximum values. In another embodiment, the cooled path of the wire is produced by means of rotary guide elements interposed between the outlet of the oven and a tensioner positioned upstream and in the plane of symmetry of the winding system.
Dans les deux modes de réalisation, la broche double torsion et le système de renvidage sont avantageusement positionnés l'un au dessus de l'autre et sont décalés latéralement par rapport au four de fixation.In both embodiments, the double twist spindle and the winding system are advantageously positioned one above the other and are offset laterally relative to the fixing furnace.
L'invention et les avantages qu'elle apporte seront cependant mieux compris grâce aux exemples de réalisation donnés ci-après et qui sont illustrés par les schémas annexés dans lesquels :The invention and the advantages which it brings will however be better understood thanks to the exemplary embodiments given below and which are illustrated by the appended diagrams in which:
- les figures 1 et 2 sont respectivement des vues de côté et de face d'une position de travail d'une machine réalisée conformément à l'invention ;- Figures 1 and 2 are respectively side and front views of a working position of a machine produced according to the invention;
- les figures 3 et 4 sont des vues similaires aux figures 1 et 2 d'une variante concernant la manière dont est réalisé le refroidissement du fil sur une machine conforme à l'invention ;- Figures 3 and 4 are views similar to Figures 1 and 2 of a variant concerning the manner in which the cooling of the wire is carried out on a machine according to the invention;
- la figure 5 est une vue de détail, schématique du moyen utilisé pour assurer la relaxation du fil pendans sa phase de refroidissement dans le mode de réalisation illustré aux figures 1 et 2 ;- Figure 5 is a detail view, schematic of the means used to ensure the relaxation of the wire during its cooling phase in the embodiment illustrated in Figures 1 and 2;
- les figures 6 et 7 sont des vues partielles montrant vue de côté (figure 6) et de face (figure 7) la structure du dispositif d'appel disposé à l'entrée du four ; - les figures 8 et 9 sont des vues partielles, agrandies montrant la structure vue de côté et de face d'une forme de réalisation du dispositif d'appel prévu en partie supérieure du four ;- Figures 6 and 7 are partial views showing side view (Figure 6) and front view (Figure 7) the structure of the call device disposed at the entrance of the oven; - Figures 8 and 9 are partial views, enlarged showing the structure seen from the side and front of an embodiment of the call device provided in the upper part of the oven;
- les figures 10 et 11 sont également des vues partielles de côté et de face d'un second type de dispositif d'appel utilisable en partie supérieure du four. En se reportant à ces figures, chaque position de travail d'une machine conforme à l'invention comporte une broche double torsion ou de câblage conventionnelle (1) permettant de réaliser soit un retordage de manière conventionnelle, soit une opération de câblage direct. De préférence, cette broche est entraînée par un moteur individuel et supporte donc une bobine (2) du fil (3) à traiter. La broche double torsion (1) permet de communiquer au fil (3) deux tours de torsion par rotation de ladite broche. Lorsqu'elle est utilisée pour réaliser une opération de câblage direct, elle présente un fût creux et un second fil est amené au travers de ce dernier pour être réuni au fil (3) porté par la broche au niveau d'une tête de câblage (4) qui est disposée dans le prolongement de l'axe de ladite broche (1).- Figures 10 and 11 are also partial side and front views of a second type of call device usable in the upper part of the oven. Referring to these figures, each working position of a machine according to the invention comprises a double twist or conventional wiring spindle (1) allowing either twisting in a conventional manner, or a direct wiring operation. Preferably, this spindle is driven by an individual motor and therefore supports a coil (2) of the wire (3) to be treated. The double twist spindle (1) makes it possible to communicate to the wire (3) two turns of twist by rotation of said spindle. When used to perform a direct wiring operation, it has a hollow barrel and a second wire is brought through the latter to be joined to the wire (3) carried by the spindle at a wiring head ( 4) which is arranged in the extension of the axis of said spindle (1).
En aval de l'ensemble double torsion ou câblage direct (1), est disposée la zone de traitement proprement dite.Downstream of the double twist or direct wiring assembly (1), the treatment zone proper is arranged.
Cette zone de traitement comporte, si l'on suit le trajet du fil, un délivreur (5) de type positif.This processing zone comprises, if the path of the wire is followed, a deliverer (5) of the positive type.
Ce délivreur est avantageusement du type illustré aux figures 6 et 7 et se compose essentiellement d'un ensemble de type à cabestan (6) et cylindre presseur (7), qui, en association avec un cylindre à gorge (20) (voir figure 7), permet d'obtenir un mouflage du fil (3) (ou du fil câblé), et donc une très grande précision dans la vitesse d'appel dudit fil ainsi qu'une annulation de la tension qui résulte de l'opération de retordage ou câblage.This deliverer is advantageously of the type illustrated in Figures 6 and 7 and consists essentially of a set of capstan type (6) and pressure cylinder (7), which, in association with a grooved cylinder (20) (see Figure 7 ), makes it possible to obtain a hauling of the wire (3) (or of the cabled wire), and therefore a very high precision in the speed of call of said wire as well as a cancellation of the tension which results from the twisting operation. or wiring.
Il convient de noter, que par mesure de clarté, le fil (3) n'a pas été représenté à la figure 2 entre la sortie de la broche (2) et le délivreur (5). Par ailleurs, le cylindre presseur (7) est montré en traits fins en position hors travail à la figure 6. Le délivreur (5) est disposé à l'entrée du four de traitement thermique proprement dit (8), four qui est disposé verticalement ou sensiblement verticalement comme illustré aux figures annexées où il forme un angle d'environ cinq degrés par rapport à la verticale.It should be noted that for clarity, the wire (3) has not been shown in Figure 2 between the output of the spindle (2) and the deliverer (5). Furthermore, the pressing cylinder (7) is shown in fine lines in the non-working position in FIG. 6. The deliverer (5) is arranged at the inlet of the actual heat treatment oven (8), an oven which is arranged vertically or substantially vertically as illustrated in the appended figures where it forms an angle of approximately five degrees with respect to the vertical .
Ce four est un four conventionnel du type de ceux utilisés sur le matériel de texturation par fausse torsion.This oven is a conventional oven of the type used on false twist texturing equipment.
Conformément à l'invention, en partie haute du four, est disposé un système d'appel et de renvoi désigné par la référence générale ( 0) et qui permet de faire effectuer au fil un second passage à l'intérieur du four (8) pendant lequel il est maintenu à l'état complètement relaxé.According to the invention, in the upper part of the oven, there is a call and forwarding system designated by the general reference (0) and which allows the wire to make a second pass inside the oven (8). during which it is kept in the fully relaxed state.
Selon la forme de réalisation illustrée aux figures 8 et 9, ce système d'appel et de renvoi (10) est constitué par un ensemble de type "détendeur de fil" ou "délivreur de survitesse", comprenant deux coupelles (20,21) entre lesquelles passe le fil, entraînées positivement en rotation, de préférence par un moteur individuel (22) tel qu'illustré aux figures 8 et 9. Un tel délivreur permet l'entraînement du fil par glissement et appelle celui-ci à une vitesse supérieure au défilement normal. Il permet, en fonction des variations de la vitesse d'appel du fil, d'obtenir automatiquement une auto-régulation de la tension en sortie du délivreur, cette tension étant maintenue à une valeur très faible.According to the embodiment illustrated in FIGS. 8 and 9, this call and forwarding system (10) is constituted by an assembly of the "wire tensioner" or "overspeed deliverer" type, comprising two cups (20,21) between which the wire passes, positively driven in rotation, preferably by an individual motor (22) as illustrated in FIGS. 8 and 9. Such a deliverer allows the wire to be driven by sliding and calls it at a higher speed normal scrolling. It allows, as a function of the variations in the call speed of the wire, to automatically obtain self-regulation of the voltage at the output of the deliverer, this voltage being maintained at a very low value.
Selon une autre forme de réalisation telle qu'illustrée aux figures 10 et 11, le système d'appel et de renvoi (10) peut être constitué par un délivreur positif du type à galet presseur. Dans un tel cas, le fil (3) passe à la surface d'un guide cylindrique (23) également entraîné en rotation par un moteur (22), le galet (24) soumis à l'action d'un élément de rappel (25) (ressort) exerçant une pression sur le fil. A la sortie du système d'appel et de renvoi (10), le fil (3), comme dit précédemment, passe une seconde fois à l'intérieur du four (8) en étant maintenu sous une tension verticale. La position verticale ou sensiblement verticale du four (8) permet de bénéficier de l'effet de gravité pour que le fil reste bien rectiligne.According to another embodiment as illustrated in FIGS. 10 and 11, the call and forwarding system (10) can be constituted by a positive delivery device of the pressure roller type. In such a case, the wire (3) passes over the surface of a cylindrical guide (23) also driven in rotation by a motor (22), the roller (24) subjected to the action of a return element ( 25) (spring) exerting pressure on the wire. At the outlet of the call and forwarding system (10), the wire (3), as said previously, passes a second time inside the oven (8) while being kept under vertical tension. The vertical or substantially vertical position of the oven (8) makes it possible to benefit from the gravity effect so that the wire remains well rectilinear.
En sortie du four (8), le fil est transféré de préférence par l'intermédiaire d'une goulotte de guidage (26) à des moyens permettant d'assurer le refroidissement du fil à l'état relaxé. La goulotte de guidage (26) a une section en forme de N.At the outlet of the oven (8), the wire is preferably transferred via a guide chute (26) to means making it possible to cool the wire in the relaxed state. The guide chute (26) has an N-shaped section.
Dans la première forme de réalisation illustrée par les figures 1, 2 et 5, les moyens permettant d'assurer le refroidissement du fil à l'état relaxé sont constitués par un tapis de relaxation (11), disposé horizontalement en-dessous du four (8). Ce tapis peut ère soit individuel pour chaque position de travail, soit commun à toutes les positions et s'étend alors sur toute la largeur du métier.In the first embodiment illustrated in FIGS. 1, 2 and 5, the means making it possible to cool the wire in the relaxed state consist of a relaxation mat (11), arranged horizontally below the oven ( 8). This mat can either be individual for each working position, or common to all positions and then extends over the entire width of the loom.
Un tel tapis (11) est déplacé à une vitesse pouvant être comprise entre 0,3 et 3 m/min et permet de réaliser une accumulation du fil permettant un refroidissement à l'état complètement relaxé. Ainsi, comme cela ressort de la figure 5, le fil (3) se dépose sur le tapis transporteur sous la forme de spires (27). La distance A entre l'extrémité de la goulotte de guidage (26) et la surface du tapis (11) conditionne la formation des spires (27), le sens de formation de la spire étant opposé au sens de torsion.Such a mat (11) is moved at a speed which can be between 0.3 and 3 m / min and makes it possible to produce an accumulation of the wire allowing cooling in the fully relaxed state. Thus, as can be seen from FIG. 5, the wire (3) is deposited on the conveyor belt in the form of turns (27). The distance A between the end of the guide trough (26) and the surface of the belt (11) conditions the formation of the turns (27), the direction of formation of the turn being opposite to the direction of torsion.
Après relaxation, le fil (3) passe sur un système de reprise (12) pour être ensuite amené au moyen de renvidage conventionnel (13). La vitesse de réception de l'ensemble de renvidage (13) est réglée par l'intermédiaire d'un détecteur de réserve (20) qui permet de réaliser une accélération pendant une durée donnée pour que le fil (3) mis en réserve sous forme de spire soit maintenu entre deux valeurs minimale 1 et maximale L prédéterminées, par exemple entre 150 mm et 350 mm de longueur.After relaxation, the thread (3) passes over a recovery system (12) to then be brought by means of conventional winding (13). The speed of reception of the winding assembly (13) is regulated by means of a reserve detector (20) which makes it possible to carry out an acceleration for a given time so that the wire (3) placed in reserve in the form of the turn is maintained between two predetermined minimum 1 and maximum L values, for example between 150 mm and 350 mm in length.
Dans le second mode de réalisation illustré aux figures 3 et 4, le refroidissement du fil est effectué en le faisant passer autour d'éléments de renvoi constitués de galets libres en rotation (14,15), le fil étant amené au système de renvidage (13) par l'intermédiaire d'un frein à hystérésis (16) réglé pour que ledit fil (3) soit maintenu en amont sous une tension minimale.In the second embodiment illustrated in FIGS. 3 and 4, the wire is cooled by passing it around return elements made up of free rotating rollers (14, 15), the wire being brought to the return system ( 13) by means of a hysteresis brake (16) adjusted so that said wire (3) is held upstream under a minimum tension.
Une telle conception de machine présente de nombreux avantages par rapport aux solutions antérieures, notamment en ce qui concerne sa souplesse d'emploi, ce qui autorise la production d'une grande variété de fils différents, et ce en jouant simplement sur le réglage des tensions que l'on communique aux fils dans les différentes zones de traitement, et ce comme le démontre les exemples concrets donnés ci-après à titre indicatif mais non limitatif.Such a machine design has many advantages over previous solutions, in particular with regard to its flexibility of use, which allows the production of a wide variety of different wires, and this by simply playing on the adjustment of the tensions. that we communicate to the son in the different treatment areas, as demonstrated by the concrete examples given below for information but not limitation.
Exemple 1Example 1

Un tel fil est réalisé sur la machine conforme à l'invention telle qu'illustrée aux figures 1 et 2, le fil (3) provenant de la bobine porté par la broche étant associé au point de câblage (4) à un second fil (non représenté) provenant d'un support additionnel monté sur le bâti de la machine et qui traverse le fût creux de la broche. Les réglages de la machine pour réaliser un tel fil câblé sont les suivants :Such a wire is produced on the machine according to the invention as illustrated in FIGS. 1 and 2, the wire (3) coming from the coil carried by the pin being associated with the wiring point (4) with a second wire ( not shown) coming from an additional support mounted on the machine frame and which crosses the hollow shaft of the spindle. The machine settings for making such a wired wire are as follows:

- température du four (8) : 220°C.- oven temperature (8): 220 ° C.
Une telle manière de procéder permet d'obtenir un fil utilisable pour la réalisation de tapis qui, par rapport à des articles réalisés à partir de fils conventionnels, présente un aspect et un toucher améliorés. Exemple 2 :Such a procedure makes it possible to obtain a yarn usable for the production of carpets which, compared to articles produced from conventional yarns, has an improved appearance and feel. Example 2:
