Description

La fabrication des fils textiles, chimiques notamment, implique de réaliser une pluralité d'opérations successives au cours desquelles il est nécessaire de transférer ledit fil depuis une source d'alimentation, enroulement de filature par exemple, sur un nouveau support (bobine, tube) permettant son utilisation lors d'une phase ultérieure de transformation. Très souvent, lors de cette opération de bobinage, le fil est soumis à un traitement complémentaire, tel que par exemple un traitement d'étirage s'il s'agit d'un fil non ou partiellement étiré, un traitement de texturation pour lui conférer des propriétés de gonflant et/ou d'élasticité ... .The manufacture of textile yarns, particularly chemical yarns, involves carrying out a plurality of successive operations during which it is necessary to transfer said yarn from a power source, winding of spinning for example, to a new support (spool, tube) allowing its use during a later phase of transformation. Very often, during this winding operation, the yarn is subjected to an additional treatment, such as for example a drawing treatment if it is an un or partially drawn yarn, a texturing treatment to give it properties of bulking and / or elasticity ....

Toutes les machines textiles permettant de réaliser le bobinage d'un fil provenant d'un support d'alimentation avec un traitement intermédiaire éventuel lors de cette opération, sont constituées d'un nombre important de positions de travail identiques, disposées côte à côte, chaque position de travail comprenant au moins, en suivant le trajet du fil :

  • une alimentation du fil à traiter,
  • au moins un premier système d'appel (dénommé également délivreur ou fournisseur de fil), permettant de délivrer le fil à une vitesse prédéterminée ;
  • un système de renvidage du fil autour d'un support entraîné en rotation et qui comporte un ensemble guide-fil, animé d'un mouvement de va-et-vient, distribuant le fil le long d'une génératrice du support et permettant de réaliser la construction de la bobine proprement dite.
All the textile machines making it possible to wind a thread coming from a supply support with an optional intermediate treatment during this operation, consist of a large number of identical working positions, arranged side by side, each working position comprising at least, following the path of the wire:
  • a supply of the wire to be treated,
  • at least a first calling system (also known as a wire supplier or supplier), making it possible to deliver the wire at a predetermined speed;
  • a wire winding system around a support driven in rotation and which comprises a wire guide assembly, driven back and forth, distributing the wire along a generatrix of the support and making it possible to produce the construction of the coil itself.

Dans de nombreuses machines textiles, en fonction des traitements à réaliser, outre le système d'appel précité et qui est donc disposé immédiatement en amont du système de renvidage, un second système d'appel dit "appel préliminaire", permet, si on le souhaite, d'effectuer entre ces deux éléments, un traitement complémentaire tel que par exemple un traitement d'étirage (à chaud ou à froid), un traitement thermique, par exemple pour effectuer la rétraction du fil, ou un traitement de texturation (notamment par fausse torsion).In many textile machines, depending on the treatments to be carried out, in addition to the aforementioned call system and which is therefore arranged immediately upstream of the winding system, a second call system called "preliminary call" allows, if it is wishes, to carry out between these two elements, a complementary treatment such as for example a stretching treatment (hot or cold), a heat treatment, for example to effect the retraction of the yarn, or a texturing treatment (in particular by false twist).

Dans toutes ces machines textiles, différents types de conception de systèmes de renvidage sont actuellement proposés, les deux plus répandus consistant soit à entraîner l'ensemble des bobines de la machine au moyen d'un arbre moteur continu, entraîné à vitesse constante, contre lequel elles sont maintenues en appui, soit à entraîner individuellement chaque bobine par un moteur.In all these textile machines, different types of winding system design are currently proposed, the two most widespread consisting either of driving all of the machine coils by means of a continuous motor shaft, driven at constant speed, against which they are kept in contact, either to drive each coil individually by a motor.

L'invention vise un procédé perfectionné portant sur ce dernier type de machine dans laquelle chaque bobine de réception est entraînée par un moteur individuel.The invention relates to an improved method relating to the latter type of machine in which each receiving coil is driven by an individual motor.

Sur de telles machines, le principal problème qui se pose est celui de régler et de contrôler en permanence la vitesse de rotation de la bobine de réception, car il est indispensable d'avoir une vitesse de renvidage constante si l'on veut obtenir des enroulements présentant des caractéristiques régulières (dureté, densité..), qui conditionnent le bon déroulement des traitements ultérieurs que doit subir le fil. Les conditions opératoires doivent par ailleurs être identique d'une position à une autre afin que les fils produits soient tous strictement identiques.On such machines, the main problem that arises is that of permanently regulating and controlling the rotation speed of the take-up reel, because it is essential to have a constant winding speed if one wants to obtain windings. having regular characteristics (hardness, density, etc.), which condition the smooth running of the subsequent treatments that the wire must undergo. The operating conditions must also be identical from one position to another so that the yarns produced are all strictly identical.

Or on a trouvé, et c'est ce qui fait l'objet de la présente invention, un procédé perfectionné qui permet de régler et contrôler avec précision la vitesse de rotation de l'ensemble de réception au fur et à mesure de la formation de la bobine (augmentation de son diamètre), et ce de telle sorte que non seulement la vitesse de renvidage du fil soit maintenue constante, mais qu'également la tension du fil en cours de défilement soit maintenue à un niveau constant prédéterminé.However, we have found, and this is the subject of the present invention, an improved method which makes it possible to precisely adjust and control the speed of rotation of the reception assembly as the formation of the spool (increase in its diameter), and such that not only the wire winding speed is kept constant, but also that the tension of the wire during running is kept at a predetermined constant level.

D'une manière générale, l'invention concerne donc un procédé de renvidage (ou bobinage) d'un fil sur une machine textile pouvant comporter un nombre important de positions de travail identiques, disposées côte à côte, chaque position de travail comprenant au moins, en suivant le trajet du fil :

  • une alimentation du fil à traiter;
  • au moins un système d'appel, permettant de délivrer le fil à une vitesse prédéterminée ;
  • un système de renvidage du fil autour d'un support entraîné en rotation par un moteur électrique et comportant un ensemble guide-fil, animé d'un mouvement de va-et-vient, distribuant le fil le long d'une génératrice du support de réception pour réaliser la construction de la bobine proprement dite.
In general, the invention therefore relates to a method of winding (or winding) a thread on a textile machine which may include a large number of identical working positions, arranged side by side, each working position comprising at least , following the path of the wire:
  • a supply of the wire to be treated;
  • at least one calling system, making it possible to deliver the wire at a predetermined speed;
  • a wire winding system around a support driven in rotation by an electric motor and comprising a wire guide assembly, driven back and forth, distributing the wire along a generator of the support reception to carry out the construction of the coil itself.

Le procédé selon l'invention se caractérise en ce que:

  • l'entraînement du système d'appel est assuré par l'intermédiaire d'un moteur associé à un convertisseur de fréquences ;
  • le moteur assurant l'entraînement du support de réception, est également associé à un convertisseur de fréquences et ;
  • un détecteur de tension mesure la tension du fil entre le système de réception et le système d'appel, et donne un signal au convertisseur de fréquences associé au moteur du système de renvidage entrainant en rotation le support de réception du fil, signal tel que si la tension du fil est supérieure à un seuil pré-réglé, la vitesse de rotation du support de réception est automatiquement diminuée, alors que si la tension est inférieure à un seuil pré-réglé, la vitesse de rotation du support de réception est augmentée permettant ainsi d'obtenir non seulement une tension du fil constante, mais également une vitesse linéaire d'enroulage constante.
The method according to the invention is characterized in that:
  • the call system is driven by a motor associated with a frequency converter;
  • the motor ensuring the drive of the reception support, is also associated with a frequency converter and;
  • a tension detector measures the tension of the thread between the reception system and the calling system, and gives a signal to the frequency converter associated with the motor of the winding system rotating the support of reception of the thread, signal as if the thread tension is higher than a preset threshold, the speed of rotation of the receiving support is automatically decreased, while if the tension is lower than a preset threshold, the rotation speed of the receiving support is increased allowing thus obtaining not only a constant thread tension, but also a constant linear winding speed.

Selon une forme de mise en oeuvre du procédé conforme à l'invention, le système d'appel qui permet de délivrer le fil au moyen de renvidage, est précédé d'un second système d'appel préliminaire permettant de réaliser entre ces deux ensembles un traitement complémentaire tel que par exemple un étirage du fil, un simple traitement thermique, un traitement de texturation, par fausse torsion notamment.According to one form of implementation of the method according to the invention, the call system which makes it possible to deliver the wire by means of winding, is preceded by a second preliminary call system making it possible to carry out between these two sets a additional treatment such as for example drawing the yarn, a simple heat treatment, a texturing treatment, in particular by false twisting.

L'invention et les avantages qu'elle apporte seront cependant mieux compris grâce à la description qui suit et qui est illustrée par les schémas annexés dans lesquels :

  • la figure 1 est une vue schématique d'une position de travail d'une machine textile mettant en oeuvre le procédé conforme à l'invention ;
  • les figures 2,3 et 4,5 illustrent, respectivement vus de côté et en élévation, deux exemples de réalisation de machines textiles permettant la mise en oeuvre du procédé conforme à l'invention, les figures 2 et 3 correspondant au cas le plus simple dans lequel on effectue un simple renvidage du fil sans traitement lors de cette opération, et les figures 4 et 5 à une machine permettant d'effectuer un étirage lors de l'opération de renvidage du fil.
The invention and the advantages which it brings will however be better understood thanks to the description which follows and which is illustrated by the appended diagrams in which:
  • Figure 1 is a schematic view of a working position of a textile machine implementing the method according to the invention;
  • Figures 2,3 and 4,5 illustrate, respectively viewed from the side and in elevation, two embodiments of textile machines allowing the implementation of the method according to the invention, Figures 2 and 3 corresponding to the simplest case in which a simple winding of the wire is carried out without treatment during this operation, and FIGS. 4 and 5 to a machine making it possible to carry out a drawing during the operation of winding the wire.

La figure 1 illustre de manière schématique, comme indiqué précédemment, l'ensemble des éléments entrant dans la réalisation d'une position de travail d'une machine de renvidage mettant en oeuvre un processus opératoire conforme à l'invention, les mêmes références que celles utilisées pour décrire cette figure étant reprises dans les deux exemples concrets de réalisation illustrés respectivement par les figures 2,3 et 4,5.Figure 1 schematically illustrates, as indicated above, all of the elements involved in achieving a working position of a winding machine implementing an operating process according to the invention, the same references as those used to describe this figure being included in the two concrete embodiments illustrated respectively in Figures 2,3 and 4,5.

Si l'on se reporte aux schémas annexés, les machines textiles adaptées pour mettre en oeuvre le procédé conforme à l'invention, sont constituées par une ou plusieurs positions de travail identiques, désignées par la même référence générale (1), et qui sont disposées côte à côte. De préférence, la machine est conçue de telle sorte que deux positions de travail identiques soient disposées de part et d'autre d'une partie centrale définissant ainsi, sur chaque côté de la machine, deux faces respectivement avancées référencées (G) et (D) aux figures 2 et 4, auxquelles l'opérateur a accès.If reference is made to the appended diagrams, the textile machines suitable for implementing the method according to the invention consist of one or more identical working positions, designated by the same general reference (1), which are arranged side by side. Preferably, the machine is designed so that two identical working positions are arranged on either side of a central part thus defining, on each side of the machine, two respectively advanced faces referenced (G) and (D ) in Figures 2 and 4, to which the operator has access.

Chaque position de travail comprend au moins, dans l'ordre du trajet du fil (2) :

  • une alimentation (3) (support de filature par exemple) du fil (2) à traiter ;
  • un premier système d'appel (4), dénommé également "délivreur" ou "fournisseur de fil", éventuellement précédé d'un système d'appel préliminaire (5) si l'on souhaite effectuer, entre ces deux éléments (4,5), un traitement complémentaire tel qu'un étirage et/ou traitement de texturation du fil (2) ;
  • un système de renvidage désigné par la référence générale (6), conventionnel, permettant de réceptionner le fil (2) autour d'un support entraîné en rotation par un moteur électrique (7), la distribution du fil étant assurée par un ensemble guide-fil (18) conventionnel, animé d'un mouvement de va-et-vient et qui distribue le fil le long d'une génératrice du support de réception et permet donc de réaliser la construction de la bobine proprement dite.
Each working position comprises at least, in the order of the path of the wire (2):
  • a supply (3) (spinning support for example) of the yarn (2) to be treated;
  • a first call system (4), also called "deliverer" or "wire supplier", possibly preceded by a preliminary call system (5) if one wishes to carry out, between these two elements (4,5 ), an additional treatment such as drawing and / or texturing treatment of the yarn (2);
  • a winding system designated by the general reference (6), conventional, making it possible to receive the wire (2) around a support driven in rotation by an electric motor (7), the distribution of the wire being ensured by a guide assembly conventional wire (18), driven back and forth and which distributes the wire along a generatrix of the receiving support and therefore allows the construction of the coil itself.

Dans l'exemple de mise en oeuvre illustré par les figures 2 et 3, le procédé conforme à l'invention est appliqué au cas d'une machine plus simple dans laquelle on réalise un simple transfert du fil depuis un support de filature (3) sur un nouveau support (6) adapté pour une utilisation ou transformation ultérieure (teinture par exemple).In the implementation example illustrated by Figures 2 and 3, the method according to the invention is applied to the case of a simpler machine in which a simple transfer of the yarn is carried out from a spinning support (3) on a new support (6) suitable for later use or transformation (dye for example).

La forme d'application illustrée par les figures 4 et 5, illustre le cas d'une machine dans laquelle un système d'appel préliminaire (5) est disposé en amont du système d'appel (4). Une telle conception de machine est par exemple utilisée pour réaliser l'étirage de fils synthétiques. Entre ces deux systèmes d'appel (4,5), peuvent éventuellement disposés des moyens permettant d'effectuer un traitement complémentaire sur le fil, par exemple un traitement thermique ou un traitement de texturation, par fausse torsion notamment. Dans un tel cas, en fonction de la longueur qu'implique le traitement à réaliser, les systèmes d'appel (4,5) seront, bien entendu, plus ou moins espacés l'un de l'autre pour pouvoir y disposer les moyens de traitement complémentaires. Par exemple, dans le cas d'un traitement de texturation par fausse torsion, entre ces deux systèmes d'appel (4) et (5), sont donc disposés, dans l'ordre de passage du fil, un four et une broche de fausse torsion, ces deux éléments étant séparés l'un de l'autre par une zone où le fil peut se refroidir.The form of application illustrated in FIGS. 4 and 5 illustrates the case of a machine in which a preliminary call system (5) is arranged upstream of the call system (4). Such a machine design is, for example, used to carry out the drawing of synthetic yarns. Between these two calling systems (4, 5), means may optionally be provided for carrying out an additional treatment on the wire, for example a heat treatment or a texturing treatment, by false twist. especially. In such a case, depending on the length involved in the processing to be carried out, the call systems (4,5) will, of course, be more or less spaced from one another in order to be able to dispose of the means there additional treatment. For example, in the case of a texturing treatment by false twist, between these two calling systems (4) and (5), are therefore arranged, in the order of passage of the wire, an oven and a spindle false twist, these two elements being separated from each other by an area where the wire can cool.

Comme moyens permettant la mise en oeuvre du procédé selon l'invention, on utilisera des systèmes d'appel (4,5) constitués par des délivreurs du type à entraînement positif. Ces délivreurs peuvent être du type constitué par une même ligne d'arbres communs à l'ensemble des positions de travail, entraînés par un moteur électrique (8) à courant alternatif triphasé associé à un convertisseur de fréquences (9). Dans le mode de réalisation tel qu'illustré aux figures 1 et 2, qui comporte donc deux systèmes d'appel espacés l'un de l'autre, on réalise l'entraînement de la série de délivreurs (4), la commande des systèmes d'appel (5) étant obtenue à partir des délivreurs (4) par un système à poulies et courroies (20). Bien entendu, il pourrait être envisagé de commander séparément les deux systèmes délivreurs (4,5) par un moteur électrique associé à un convertisseur de fréquences. Les vitesses respectives desdits délivreurs (4,5) sont adaptées en fonction des traitements à réaliser.As means allowing the implementation of the method according to the invention, call systems (4,5) made up of deliverers of the positive drive type will be used. These deliverers can be of the type constituted by the same line of shafts common to all the working positions, driven by an electric motor (8) with three-phase alternating current associated with a frequency converter (9). In the embodiment as illustrated in FIGS. 1 and 2, which therefore comprises two call systems spaced from one another, the drive of the series of deliverers (4) is carried out, the control of the systems call (5) being obtained from the deliverers (4) by a pulley and belt system (20). Of course, it could be envisaged to control the two delivery systems (4,5) separately by an electric motor associated with a frequency converter. The respective speeds of said deliverers (4,5) are adapted as a function of the treatments to be carried out.

Il peut également être envisagé d'appliquer l'invention aux machines textiles dans lesquelles les délivreurs (4) sont entraînés individuellement par un moteur intégré.It can also be envisaged to apply the invention to textile machines in which the deliverers (4) are driven individually by an integrated motor.

Il convient également de noter que pour la mise en oeuvre du procédé conforme à l'invention, l'entraînement des systèmes de réception (6) est assuré de manière individuelle pour chaque position par l'intermédiaire d'un moteur (7) associé à un convertisseur de fréquences (10).It should also be noted that for the implementation of the method according to the invention, the reception systems (6) are driven individually for each position by means of a motor (7) associated with a frequency converter (10).

Par ailleurs, chaque position comporte également un détecteur de tension (11) qui mesure la tension de chaque fil (2) entre le support de réception (6) et le système délivreur (4). Des moyens de contrôle (casse-fil) sont également prévus pour arrêter la position lors d'un incident (casse) ou lorsque le support d'enroulement atteint un diamètre prédéterminé.Furthermore, each position also includes a tension detector (11) which measures the tension of each thread (2) between the receiving support (6) and the delivery system (4). Control means (wire breakers) are also provided to stop the position during an incident (breakage) or when the winding support reaches a predetermined diameter.

Grâce à une telle conception de machine, il est donc possible d'obtenir non seulement un contrôle parfait de la vitesse du fil donnée par le ou les systèmes d'appel (4) et (5), cette vitesse étant strictement identique pour toutes les positions de travail d'une même face de la machine, mais par ailleurs, il est possible de régler automatiquement la vitesse de réception de chaque position, et ce quel que soit le diamètre de l'enroulement formé de manière à obtenir une vitesse de réception constante. En effet, chaque détecteur de tension (11) permet de mesurer la tension de chaque fil entre le système de réception (6) et le système délivreur (4), et d'envoyer un signal au convertisseur de fréquences (10) associé au moteur de réception (7). Si la tension du fil est supérieure à un seuil pré-réglé, la vitesse de rotation de la bobine de réception est automatiquement diminuée, alors que si la tension est inférieure à un seuil pré-réglé, ladite vitesse de rotation de la bobine de réception est augmentée.Thanks to such a machine design, it is therefore possible not only to obtain perfect control of the speed of the wire given by the call system (s) (4) and (5), this speed being strictly identical for all working positions on the same side of the machine, but moreover, it is possible to automatically adjust the reception speed of each position, regardless of the diameter of the winding formed so as to obtain a reception speed constant. Indeed, each voltage detector (11) makes it possible to measure the tension of each wire between the reception system (6) and the delivery system (4), and to send a signal to the frequency converter (10) associated with the motor. reception (7). If the thread tension is higher than a preset threshold, the speed of rotation of the take-up reel is automatically reduced, while if the tension is lower than a preset threshold, said speed of rotation of the take-up reel is increased.

Grâce à une telle conception des moyens de commande d'entraînement des organes en rotation que comporte une machine textile, il est possible non seulement d'obtenir un réglage précis des vitesses de rotation, mais également de contrôler et d'ajuster en permanence ces vitesses en cours de fonctionnement. De plus, il est possible de réaliser des machines permettant d'avoir un cavage (remplacement d'une bobine pleine par une bobine vide) automatique individuel à la position, l'opération étant commandée automatiquement dès que la bobine atteint un diamètre déterminé, et ce sans modifier le fonctionnement des autres positions de la machine.Thanks to such a design of the means of controlling the driving of the rotating members which a textile machine comprises, it is possible not only to obtain a precise adjustment of the rotational speeds, but also to continuously control and adjust these speeds. during operation. In addition, it is possible to make machines making it possible to have an automatic automatic digging (replacement of a full coil with an empty coil) at the position, the operation being controlled automatically as soon as the coil reaches a determined diameter, and this without modifying the operation of the other machine positions.

Enfin, l'ensemble des moyens est piloté par l'intermédiaire d'un automate programmable qui permet de modifier rapidement et pratiquement instantanément le règlage de la machine en fonction du fil traité.Finally, all of the means are controlled by means of a programmable automaton which allows the adjustment of the machine to be changed quickly and practically instantaneously as a function of the wire treated.

Bien entendu, l'invention n'est pas limitée à l'exemple qui précède, mais elle en couvre toutes les variantes réalisées dans le même esprit.Of course, the invention is not limited to the preceding example, but it covers all the variants produced in the same spirit.
