Système de gestion automatisée de l'étalement d'une nappe textileAutomated management system for spreading a textile sheet
Domaine de l'invention La présente invention se rapporte au domaine des structures textiles aiguilletées et elle concerne plus particulièrement un système de gestion automatisée pour l'étalement de câbles destinés à former ces structures textiles.Field of the Invention The present invention relates to the field of needled textile structures and it relates more particularly to an automated management system for spreading cables intended to form these textile structures.
Art antérieurPrior art
Dans les processus industriels d'aiguilletage traditionnel, la nappe textile qui sera aiguilletée et servira par exemple à l'élaboration de pièces de protection utilisées aux températures élevées, est formée à partir de plusieurs câbles disposés cote à cote et composés chacun d'une multitude de fils textiles avantageusement de type monofilaments. Chaque câble est issu d'un appareil appelé râtelier et sort sur une largeur et à une position devant a priori permettre une répartition la plus uniforme possible dans la nappe (appelée aussi voile de câble).In the traditional needling industrial processes, the textile web which will be needled and will be used for example for the development of protective parts used at high temperatures, is formed from several cables arranged side by side and each composed of a multitude textile yarns advantageously of the monofilament type. Each cable comes from a device called a rack and exits over a width and at a position which should in principle allow the most uniform distribution possible in the sheet (also called cable veil).
Actuellement, cette répartition est assurée uniquement de façon manuelle par un opérateur placé en sortie du râtelier, qui scrute constamment la nappe, notamment au niveau des recouvrements entre câbles, et si c'est possible en modifie manuellement son étalement pour en limiter les imperfections. Malheureusement, lorsque ces imperfections apparaissent trop importantes, le processus doit être interrompu avec les conséquences graves qui en découlent. Outre que cette méthode est particulièrement coûteuse en personnel (notamment lorsqu'il s'agit d'assurer un processus continu 24 heures sur 24), elle n'est pas exempte de défauts de part la présence du facteur humain.Currently, this distribution is ensured only manually by an operator placed at the outlet of the rack, who constantly scans the sheet, in particular at the level of the overlaps between cables, and if possible modifies its spread manually to limit imperfections. Unfortunately, when these imperfections appear too great, the process must be interrupted with the serious consequences that ensue. Besides that this method is particularly costly in terms of personnel (especially when it is a question of ensuring a continuous process 24 hours a day), it is not free from defects due to the presence of the human factor.
Objet et définition de l'inventionObject and definition of the invention
La présente invention pallie ces inconvénients en proposant un dispositif de gestion automatisée de l'étalement d'une nappe textile formée à partir d'une pluralité de câbles issus d'un module d'alimentation de câbles et destinée à alimenter un module d'entraînement, caractérisé en ce qu'il comporte des moyens pour mesurer la position des bords longitudinaux de chaque câble, des moyens pour régler individuellement la largeur de chaque câble, des moyens pour régler individuellement la position de chaque câble dans une direction perpendiculaire à une direction d'avancée des câbles, et des moyens de traitement numérique pour, à partir desdits moyens de mesure de position, commander lesdits moyens de réglage, de telle sorte que ladite nappe textile présente une largeur et une position déterminées.The present invention overcomes these drawbacks by proposing an automated device for managing the spreading of a textile sheet formed from a plurality of cables from a cable supply module and intended to supply a drive module. , characterized in that it comprises means for measuring the position of the longitudinal edges of each cable, means for adjusting individually the width of each cable, means for individually adjusting the position of each cable in a direction perpendicular to a direction of advance of the cables, and digital processing means for, from said position measuring means, controlling said means of adjustment, so that said textile sheet has a determined width and position.
Avec cette configuration particulière, il est possible d'obtenir automatiquement une répartition uniforme de la nappe textile dont la largeur et la position sont ainsi parfaitement garanties et contrôlées en temps réel pour permettre son introduction dans un module de préaiguilletage ou directement dans un étaleur/nappeur.With this particular configuration, it is possible to automatically obtain a uniform distribution of the textile web whose width and position are thus perfectly guaranteed and controlled in real time to allow its introduction into a pre-needling module or directly into a spreader / lapper. .
Avantageusement, les moyens de mesure de la position des bords longitudinaux de chaque câble comportent soit une caméra numérique disposée au dessus de la nappe textile soit un détecteur, de préférence un capteur linéaire optique formé d'une pluralité de diodes émettrices disposées en regard d'une pluralité de diodes réceptrices et entre lesquelles va passer le câble à mesurer. De même, les moyens de réglage individuel de la largeur de chaque câble comportent une barre banane de réglage dont le pivotement autour d'un axe de rotation sous l'action d'un premier vérin a pour effet, en modifiant la position de la courbure de sa partie centrale, d'agir sur la largeur du câble passant sur cette barre banane de réglage. Pareillement, les moyens de réglage individuel de la position de chaque câble dans une direction perpendiculaire à une direction d'avancée des câbles comportent un second vérin, agissant sur un axe de liaison pour déplacer, au moyen d'un bras de commande, une balancelle de support de ce câble. Les premiers et seconds vérins sont de préférence des vérins à commande électrique actionnés directement par lesdits moyens de traitement numérique.Advantageously, the means for measuring the position of the longitudinal edges of each cable comprise either a digital camera placed above the textile web or a detector, preferably a linear optical sensor formed by a plurality of emitting diodes arranged opposite a plurality of receiving diodes and between which the cable to be measured will pass. Likewise, the means for individually adjusting the width of each cable comprise a banana adjustment bar whose pivoting about an axis of rotation under the action of a first jack has the effect of modifying the position of the curvature. from its central part, to act on the width of the cable passing over this adjustment banana bar. Similarly, the means for individually adjusting the position of each cable in a direction perpendicular to a direction of advance of the cables comprise a second cylinder, acting on a connecting axis to move, by means of a control arm, a swing to support this cable. The first and second cylinders are preferably electrically actuated cylinders actuated directly by said digital processing means.
Les moyens de traitement numérique comportent un microcalculateur ou un automate programmable qui, à partir desdites mesures relevées par lesdits détecteurs de position, commande lesdits premiers et seconds vérins de réglage de la largeur et de la position de chaque câble, de façon à assurer une régulation de la largeur et de la position de ladite nappe textile par rapport à des valeurs de consigne prédéterminée. Avantageusement, ces valeurs de consigne prédéterminée comportent une largeur totale de nappe Ne, un recouvrement nominal entre câbles R1c, R2c, R3c et une largeur individuelle de câble Le. Toutefois, seules les valeurs de consigne relatives à ladite largeur totale de nappe et lesdits recouvrements nominaux sont fournies auxdits moyens de traitement numérique par un opérateur, la valeur de consigne relative à ladite largeur individuelle de câble étant calculée automatiquement par lesdits moyens de traitement à partir desdites consignes fournies par l'opérateur.The digital processing means comprise a microcomputer or a programmable automaton which, on the basis of said measurements recorded by said position detectors, controls said first and second actuators for adjusting the width and the position of each cable, so as to ensure regulation the width and the position of said textile sheet with respect to predetermined set values. Advantageously, these predetermined set values include a total width of the sheet Ne, a nominal overlap between cables R1c, R2c, R3c and an individual cable width Le. However, only the set values relating to said total width of the ply and said nominal recoveries are supplied to said digital processing means by an operator, the set value relating to said individual cable width being calculated automatically by said processing means from said instructions provided by the operator.
L'invention concerne également le procédé mis en œuvre dans ce dispositif de gestion automatisée de l'étalement d'une nappe textile.The invention also relates to the process implemented in this automated management device for spreading a textile sheet.

Description détaillée d'un mode de réalisation préférentielDetailed description of a preferred embodiment
Un dispositif de gestion automatisée de l'étalement d'une nappe textile est illustré de façon schématique sur la figure 1.An automated device for managing the spreading of a textile sheet is shown diagrammatically in FIG. 1.
Ce dispositif 10 prend place dans un râtelier traditionnel entre un module d'alimentation des câbles 12 et un module d'entraînement de ces câbles 14. Ce module d'entraînement peut également être intégré à un module de préaiguilletage ou à un étaleur/nappeur. Dans l'exemple illustré, le module d'alimentation 12 qui est disposé dans un plan supérieur par rapport au module d'entraînement, délivre quatre câbles 16a, 16b, 16c, 16d qui sortent selon une direction d'avancée entre des barres de détour respectives 120a, 120b, 120c, 120d disposées sur quatre niveaux différents. Bien entendu, ce nombre de câbles n'est en aucune façon limitatif et le recours à un nombre inférieur (au moins deux) ou supérieur, sans autre limitation que l'espace disponible pour l'installation du dispositif, est tout à fait possible. Le module d'entraînement 14 comporte quant à lui une série de rouleaux de prise 140 (appelé aussi presse d'entraînement) qui reprennent et entraînent la nappe formée des quatre câbles précédents et uniformément répartie par le dispositif de gestion de l'étalement 10 selon l'invention.This device 10 takes place in a traditional rack between a cable supply module 12 and a drive module for these cables 14. This drive module can also be integrated into a pre-needling module or a spreader / lapper. In the example illustrated, the supply module 12 which is arranged in an upper plane relative to the drive module, delivers four cables 16a, 16b, 16c, 16d which exit in a direction of advance between the detour bars 120a, 120b, 120c, 120d respectively arranged on four different levels. Of course, this number of cables is in no way limiting and the use of a lower number (at least two) or more, with no other limitation than the space available for installation of the device is entirely possible. The drive module 14 for its part comprises a series of pick rollers 140 (also called drive press) which take up and drive the sheet formed from the previous four cables and uniformly distributed by the spreading management device 10 according to the invention.
Ce dispositif automatisé comporte, montés entre de deux montants latéraux 100, 102, formant bâti quatre premières traverses support 104a, 104b, 104c, 104d, formant rail de guidage, disposés sur quatre niveaux différents légèrement décalés par rapport aux quatre niveaux des barres de détour, chaque première traverse support portant une balancelle (ou portique) 106a, 106b, 106c, 106d mobile transversalement entre ces montants, dans une direction perpendiculaire à la direction d'avancée des câbles, et destinée à supporter le câble durant sa traversée du dispositif. Sur une partie supérieure de cette balancelle (au niveau de sa traverse support), et de chaque côté de celle-ci, sont fixées, comme le montrent les figures 2 et 3, deux flasques latéraux 108a, 108b, 108c, 108d ; 108'a, 108'b, 108'c, 108'd entre lesquels sont montées décalées l'une au dessus de l'autre une première barre de centrage fixe 110a, 110b, 110c, 110d et des moyens de réglage de la largeur du câble formés par une barre de réglage 112a, 112b, 112c, 112d mobile autour d'un axe 114a, 114b, 114c, 114d dont la rotation est commandée par un premier vérin 116a, 116b, 116c, 116d, de préférence à commande électrique, monté sur la balancelle. La barre de centrage fixe qui est sensiblement alignée sur les barres de détour est de préférence une barre banane, c'est à dire présentant une forme incurvée dans sa partie centrale. Toutefois, une barre de centrage droite est aussi envisageable. La barre de réglage mobile est par contre nécessairement une barre banane, son pivotement autour de son axe de rotation sous l'action du premier vérin ayant pour effet de modifier la position de la courbure de sa partie centrale qui, en passant d'une forme creuse à une forme bombée, va agir sur la largeur du câble passant sur cette barre banane. Ainsi, à une position bombée correspondra une largeur plus grande que celle correspondant à une position creuse. La commande du déplacement transversal de chaque balancelle qui assure un réglage individuel de la position de chaque câble est illustrée sur les figures 3 et 4 qui montrent quatre seconds vérins 118a, 118b, 118c, 118d, de préférence à commande électrique, agissant sur un axe 120a, 120b, 120c, 120d de liaison avec une partie inférieure de la balancelle par l'intermédiaire d'un bras de commande 122a, 122b, 122c, 122d. Ces seconds vérins sont avantageusement montés dans un 102 des montants latéraux du bâti. Sur cette partie inférieure de la balancelle est également montée, sensiblement au niveau de la presse d'entraînement 140, une seconde barre de centrage fixe 124a, 124b, 124c, 124d faisant fonction de barre de détour pour ramener le câble descendant le long de la balancelle vers l'entrée du module d'entraînement 14.This automated device comprises, mounted between two lateral uprights 100, 102, forming a frame four first support crosspieces 104a, 104b, 104c, 104d, forming a guide rail, arranged on four different levels slightly offset from the four levels of the detour bars , each first support crosspiece carrying a swing (or gantry) 106a, 106b, 106c, 106d movable transversely between these uprights, in a direction perpendicular to the direction of advance of the cables, and intended to support the cable during its crossing of the device. On an upper part of this swing (at its support cross member), and on each side thereof, are fixed, as shown in Figures 2 and 3, two lateral flanges 108a, 108b, 108c, 108d; 108'a, 108'b, 108'c, 108'd between which are offset offset one above the other a first fixed centering bar 110a, 110b, 110c, 110d and means for adjusting the width of the cable formed by an adjustment bar 112a, 112b, 112c, 112d movable around an axis 114a, 114b, 114c, 114d whose rotation is controlled by a first jack 116a, 116b, 116c, 116d, preferably electrically controlled , mounted on the swing. The fixed centering bar which is substantially aligned with the detour bars is preferably a banana bar, that is to say having a curved shape in its central part. However, a straight centering bar is also possible. The movable adjustment bar, on the other hand, is necessarily a banana bar, its pivoting about its axis of rotation under the action of the first cylinder having the effect of modifying the position of the curvature of its central part which, passing from a shape hollow to a curved shape, will act on the width of the cable passing over this banana bar. Thus, a domed position will correspond to a width greater than that corresponding to a hollow position. The control of the transverse movement of each swing which provides an individual adjustment of the position of each cable is illustrated in Figures 3 and 4 which show four second cylinders 118a, 118b, 118c, 118d, preferably electrically operated, acting on an axis 120a, 120b, 120c, 120d connecting with a lower part of the swing by means of a control arm 122a, 122b, 122c, 122d. These second cylinders are advantageously mounted in a 102 of the lateral uprights of the frame. On this lower part of the swing is also mounted, substantially at the level of the drive press 140, a second fixed centering bar 124a, 124b, 124c, 124d acting as a detour bar to bring the cable down along the swing towards the entrance of the drive module 14.
Les mesures de la largeur et de la position de chaque câble dans la nappe desquelles sera déduite la largeur totale de la nappe sont assurées par quatre détecteurs montés chacun sur une seconde traverse support 126a, 126b, 126c, 126d, disposé également entre les montants latéraux 100, 102, sensiblement au niveau de la partie inférieure de la balancelle. Chaque détecteur 128a, 128b, 128c, 128d, avantageusement constitué par un capteur linéaire optique (de préférence une rampe de lumière infrarouge de largeur supérieure à celle d'un câble individuel) formé d'une pluralité de diodes émettrices 130a, 130b, 130c, 130d et de diodes réceptrices 132a, 132b, 132c, 132d disposées en regard et entre lesquelles va passer le câble à mesurer, est monté sur la seconde traverse support de façon à assurer une détection au moins au niveau des deux côtés longitudinaux du câble, et de préférence sur toute sa largeur. On notera que l'on peut avantageusement remplacer ces détecteurs par une unique caméra numérique placée dans une position telle, au dessus de la nappe textile, qu'elle puisse couvrir dans son champ de vision toute la largeur de cette nappe.The measurements of the width and the position of each cable in the sheet from which the total width of the sheet will be deducted are provided by four detectors each mounted on a second support cross member 126a, 126b, 126c, 126d, also arranged between the lateral uprights. 100, 102, substantially at the level of the lower part of the swing. Each detector 128a, 128b, 128c, 128d, advantageously constituted by an optical linear sensor (preferably an infrared light ramp of width greater than that of an individual cable) formed of a plurality of emitting diodes 130a, 130b, 130c, 130d and receiving diodes 132a, 132b, 132c, 132d arranged facing each other and between which the cable to be measured will pass, is mounted on the second support crosspiece so as to ensure detection at least at the two longitudinal sides of the cable, and preferably over its entire width. It will be noted that these detectors can advantageously be replaced by a single digital camera placed in such a position, above the textile tablecloth, that it can cover in its field of vision the entire width of this tablecloth.
Cette gestion automatisée est assurée par un moyen de traitement numérique (voir la figure 5), de préférence un microcalculateur ou un automate programmable 134, qui reçoit des informations de position des détecteurs 128a, 128b, 128c, 128d et, à partir de ces informations et de paramètres internes actionne les différents vérins à commande électrique 116a, 116b, 116c, 116d ;118a, 118b, 118c, 118d assurant la commande du déplacement des barres de réglage et des balancelles. Les paramètres pris en compte sont essentiellement la vitesse d'avancée des câbles devant former la nappe textile et la distance existant entre les détecteurs et l'axe de rotation des barres de réglage. Ce calculateur réalise en fait en temps réel une régulation par rapport à trois valeurs de consigne : une largeur totale de nappe souhaitée (largeur totale de consigne Ne), un recouvrement nominal entre câble désiré (recouvrements de consigne R1c, R2c, R3c), et une largeur individuelle de câble (largeur individuelle de consigne Le), de façon à obtenir une répartition uniforme des fibres textiles constituant la nappe. Seules les deux premières valeurs de consignes sont fournies par l'opérateur au moyen de traitement numérique qui calcule alors automatiquement la consigne Le. A titre d'exemple, on a pu obtenir d'excellents résultats avec les consignes suivantes : Ne = 530 mm, R1c = R2c = R3c = 10 mm, Le = 140 mm.This automated management is ensured by a digital processing means (see FIG. 5), preferably a microcomputer or a programmable controller 134, which receives position information from the detectors 128a, 128b, 128c, 128d and, from this information and internal parameters operate the various electrically actuated cylinders 116a, 116b, 116c, 116d; 118a, 118b, 118c, 118d ensuring the movement of the adjustment bars and swings. The parameters taken into account are essentially the speed of advance of the cables which are to form the textile sheet and the distance existing between the detectors and the axis of rotation of the adjustment bars. This computer in fact realizes in real time a regulation with respect to three set values: a desired total ply width (total set width Ne), a nominal overlap between the desired cable (set overlaps R1c, R2c, R3c), and an individual cable width (individual set width Le), so as to obtain a uniform distribution of the textile fibers constituting the sheet. Only the first two setpoint values are provided by the operator by means of digital processing which then automatically calculates the setpoint Le. For example, excellent results have been obtained with the following instructions: Ne = 530 mm, R1c = R2c = R3c = 10 mm, Le = 140 mm.
Le fonctionnement du dispositif 10 peut s'analyser comme suit. Il suppose bien entendu que les câbles A, B, C et D, de répartition non uniforme et de largeur a priori non conforme (en générale plus petite) soient préalablement extraits du module 12, puis que la nappe N formée dans le dispositif soit introduite dans le module 14 qui assurera son entraînement. Ces câbles passent chacun successivement sur la première barre de centrage 110 puis sur la barre de réglage associée 112 qui, dans sa position initiale, présente une position de courbure conforme aux commandes de consigne, et enfin sur la seconde barre de centrage 124. Dans cette position initiale, donc avant un entraînement continu de la nappe, chaque détecteur dispose d'informations précises sur la position exacte du câble, par rapport à un référentiel fixe prédéterminé, dont il assure le contrôle. Ces informations sont les positions des deux bords longitudinaux du câble, desquelles est déduite la largeur individuelle du câble. L'ensemble des informations des quatre détecteurs permet de déterminer une valeur initiale N0 pour la largeur totale de la nappe, trois valeurs initiales (qui peuvent être identiques) pour les différents recouvrements, R10 pour le recouvrement entre les câbles A et B, R20 pour le recouvrement entre les câbles B et C, R30 pour le recouvrement entre les câbles C et D, et également quatre valeurs initiales LA0, LB0, LC0, LD0 pour les largeurs individuelles des câbles. C'est à partir de la comparaison de ces valeurs initiales et des valeurs mesurées ultérieures Ni, Ri, Li avec les valeurs de consignes prédéterminées que sera effectuée la régulation par les moyens de traitement 134.The operation of the device 10 can be analyzed as follows. It naturally assumes that the cables A, B, C and D, of non-uniform distribution and a priori non-conforming width (generally smaller) are previously extracted from the module 12, then that the sheet N formed in the device is introduced. in module 14 which will ensure its training. These cables each pass successively on the first centering bar 110 then on the associated adjustment bar 112 which, in its initial position, has a position of curvature in accordance with the setpoint commands, and finally on the second centering bar 124. In this initial position, therefore before a continuous training of the sheet, each detector has precise information on the exact position of the cable, with respect to a predetermined fixed reference frame, of which it ensures control. This information is the positions of the two longitudinal edges of the cable, from which the individual width of the cable is deducted. All the information from the four detectors makes it possible to determine an initial value N0 for the total width of the sheet, three initial values (which may be identical) for the different overlaps, R10 for the overlap between the cables A and B, R20 for the overlap between cables B and C, R30 for the overlap between cables C and D, and also four initial values LA0, LB0, LC0, LD0 for the individual widths of the cables. It is from comparison of these initial values and of the subsequent measured values Ni, Ri, Li with the predetermined set values that the regulation will be carried out by the processing means 134.
Cette régulation en temps réel s'effectue selon trois niveaux de priorités successifs, la priorité la plus élevée étant donnée à l'obtention d'une largeur totale de nappe conforme à la largeur de consigne entrée par l'opérateur. Pour cela, il est procédé en premier lieu à un réglage des câbles d'extrémité A et D pour que leurs bords extérieurs définissent la largeur de nappe voulue Ne. Ce réglage porte à la fois sur la position des deux balancelles et des deux barres de réglage supportant ces deux câbles d'extrémité. En second lieu, il est procédé à un équilibrage des recouvrements par un réglage des câbles centraux B et C pour que leurs bords respectifs se superposent entre eux et avec les bords intérieurs des deux câbles d'extrémité sensiblement de façon similaire et conforme aux recouvrements nominaux de consigne R1c, R2c, R3c entrés également par l'opérateur. Ici encore, le réglage porte à la fois sur la position des deux balancelles et des deux barres de réglage supportant ces deux câbles centraux. Enfin, en dernier lieu, un réglage portant sur l'ensemble des positions des balancelles et des barres de réglage supportant les câbles centraux et d'extrémité est effectué pour obtenir une largeur individuelle de câble conforme à la largeur individuelle de consigne Le définie par le calculateur. On notera que la largeur individuelle des câbles est régulée pour obtenir les recouvrements de consigne qui ne peuvent être eux mêmes régulés au détriment de la régulation de la largeur totale de la nappe dont le respect est prioritaire.This real-time regulation is carried out according to three successive priority levels, the highest priority being given to obtaining a total width of the sheet in accordance with the set width entered by the operator. For this, it is first carried out an adjustment of the end cables A and D so that their outer edges define the desired width of the sheet Ne. This adjustment relates both to the position of the two swings and the two adjustment bars supporting these two end cables. Secondly, the overlaps are balanced by adjusting the central cables B and C so that their respective edges overlap with each other and with the inner edges of the two end cables substantially similarly and in accordance with the nominal overlaps setpoint R1c, R2c, R3c also entered by the operator. Here again, the adjustment relates both to the position of the two swings and the two adjustment bars supporting these two central cables. Finally, lastly, an adjustment relating to all the positions of the swings and of the adjustment bars supporting the central and end cables is carried out in order to obtain an individual cable width conforming to the individual reference width Le defined by the computer. It will be noted that the individual width of the cables is regulated in order to obtain the target overlaps which cannot themselves be regulated to the detriment of regulating the total width of the sheet, the respect of which is a priority.
Dans l'exemple illustré, compte tenu de la proximité du détecteur 128 par rapport à la seconde barre de centrage 124, la correction de position d'un câble par le déplacement de la balancelle a un effet immédiat sur la position de ce câble. Par contre, la correction de largeur d'un câble par la commande de la rotation de la barre de réglage s'effectue avec un décalage de temps du fait à la fois de la distance (position déportée) existant entre ce détecteur et la barre de réglage 112 et de l'étalement non instantané des fils textiles formant le câble, d'où la nécessité de connaître (et de définir comme paramètres internes) à la fois cette distance et la vitesse d'avancée de la nappe. In the example illustrated, taking into account the proximity of the detector 128 with respect to the second centering bar 124, the correction of the position of a cable by the movement of the swing has an immediate effect on the position of this cable. On the other hand, the correction of the width of a cable by controlling the rotation of the adjustment bar is carried out with a time offset due to both the distance (offset position) existing between this detector and the bar adjustment 112 and the non-instantaneous spreading of the textile threads forming the cable, hence the need to know (and define as internal parameters) both this distance and the speed of advance of the sheet.
