Description

La présente invention se rapporte à une machine pour le traitement de pièces textiles, notamment une machine à teindre.The present invention relates to a machine for treating textile parts, in particular a dyeing machine.

Prélablement à leur traitement, il est usuel d'assembler des pièces textiles dont la taille est en moyenne de l'ordre de 50 mètres par ces coutures ; cette opération est effectuée dans un atelier dit "atelier écru" indépendant de l'atelier de traitement, et permet d'obtenir des coutures fines, c'est-à-dire sans relief. On obtient ainsi des bandes textiles dont la longueur peut être de l'ordre du kilomètre.Prior to their treatment, it is customary to assemble textile pieces whose size is on average about 50 meters by these seams; this operation is carried out in a workshop called "ecru workshop" independent of the treatment workshop, and makes it possible to obtain fine seams, that is to say without relief. Textile strips are thus obtained, the length of which can be of the order of a kilometer.

Au moment de leur introduction dans la machine de traitement, de telles bandes sont refermées sur elles-mêmes par des coutures qui sont réalisées dans l'atelier de traitement et sont donc grossières et en relief.At the time of their introduction into the treatment machine, such strips are closed on themselves by seams which are produced in the treatment workshop and are therefore coarse and in relief.

Lors du traitement, notamment de la teinture, on fait tourner ces boucles, selon un mouvement sans fin, dans une machine constituée schématiquement par une enceinte comportant un noyau central, et munie, à sa partie inférieure, d'un canal de stockage de la boucle dont le fond, en forme de cuvette, reçoit un bain de traitement, notamment un bain de teinture, et, à sa partie supérieure, d'organes d'entraînement susceptibles de relever les pièces textiles se trouvant dans le canal de stockage et de commander la rotation de la boucle dans un plan essentiellement vertical.During the treatment, in particular of the dyeing, these loops are rotated, in an endless movement, in a machine constituted schematically by an enclosure comprising a central core, and provided, at its lower part, with a channel for storing the loop whose bottom, in the form of a bowl, receives a treatment bath, in particular a dye bath, and, at its upper part, drive members capable of raising the textile pieces located in the storage channel and of controlling the rotation of the loop in an essentially vertical plane.

Compte tenu de l'importance de sa longueur, l'entraînement de la boucle pose des problèmes particulièrement délicats, notamment au cours des processus de teinture à l'aide de bains de teinture à rapport de bains courts : en effet, pour obtenir des résultats satisfaisants, associés à un temps de traitement peu important, il est nécessaire de faire circuler le produit textile à une vitesse relativement élevée.Taking into account the importance of its length, the entrainment of the loop poses particularly delicate problems, in particular during the dyeing processes using dyeing baths with a short bathing ratio: indeed, to obtain results satisfactory, associated with a short treatment time, it is necessary to circulate the textile product at a relatively high speed.

Par suite de cette obligation, il arrive fréquemment que les pièces textiles s'emmêlent ou s'écrasent en formant des plis au niveau des organes d'entraînement, ou encore, se placent de manière défectueuse au niveau du fond du canal de stockage, ce qui fait que l'on n'obtient pas toujours un résultat entièrement satisfaisant en fin de traitement.As a result of this obligation, it often happens that the textile pieces become entangled or crushed by forming folds at the level of the drive members, or else, are placed in a defective manner at the bottom of the storage channel, this which means that you do not always get a completely satisfactory result at the end of treatment.

Un autre inconvénient inhérent au processus susmentionné est lié à la possible formation de surépaisseurs qui risquent, non seulement, de nuire à la qualité du produit fini, mais également d'entraîner un endommagement de la machine elle-même.Another drawback inherent in the above-mentioned process is linked to the possible formation of extra thicknesses which risk not only damaging the quality of the finished product, but also causing damage to the machine itself.

La présente invention a pour objet de remédier à ces inconvénients en proposant une machine du type susmentionné permettant d'exclure pratiquement tout positionnement défectueux des pièces textiles lors de leur rotation.The object of the present invention is to remedy these drawbacks by proposing a machine of the aforementioned type making it possible to exclude practically any defective positioning of the textile pieces during their rotation.

Selon l'invention, cette machine est caractérisée en ce que les organes d'entraînement coopèrent à leur partie amont, dans le sens de rotation de la boucle, avec des moyens d'épanouissement et de positionnement constitués, d'une part, par des organes de ventilation susceptibles de gonfler les pièces textiles en un ballon et, d'autre part, par des organes de pincement du ballon susceptibles de permettre à la boucle de s'étaler sur toute sa largeur.According to the invention, this machine is characterized in that the drive members cooperate at their upstream part, in the direction of rotation of the loop, with spreading and positioning means constituted, on the one hand, by ventilation members capable of inflating the textile pieces into a balloon and, on the other hand, by balloon gripping members capable of allowing the loop to spread over its entire width.

Les organes d'entraînement peuvent être quelconques sans pour cela sortir du cadre de l'invention et sont avantageusement constitués par un ensemble de rotors formés d'un noyau central muni, sur son chant, de lames dont la partie voisine du bord extérieur est souple ; de tels organes d'entraînement sont, par exemple, décrits dans le brevet FR 82 14 615.The drive members can be any without departing from the scope of the invention and are advantageously constituted by a set of rotors formed of a central core provided, on its edge, with blades whose part near the outer edge is flexible ; such drive members are, for example, described in patent FR 82 14 615.

Les organes de ventilation, qui sont placés directement à la sortie du canal de stockage, ont pour effet de gonfler, d'épanouir et de dévriller les pièces textiles ainsi que de supprimer leurs plis.The ventilation members, which are placed directly at the outlet of the storage channel, have the effect of swelling, opening and untwisting the textile pieces as well as suppressing their folds.

D'une manière connue en elle-même, ces organes sont, de préférence, constitués par au moins une buse de ventilation alimentée par le gaz interne de la machine qui peut, ainsi, être recyclé et pulsé sur les pièces à traiter.In a manner known in itself, these members are preferably constituted by at least one ventilation nozzle supplied with the internal gas of the machine which can thus be recycled and pulsed on the parts to be treated.

Ce type d'organes de ventilation présente l'avantage de s'adapter à tous les types de textiles, notamment les textiles circulaires ou au large (fendus, ouverts, issus de circulaires ou au large, issus de métiers chaînes et trames ou de métiers rectilignes chaînes).This type of ventilation device has the advantage of adapting to all types of textiles, in particular circular or offshore textiles (split, open, from circulars or offshore, from warp and weft trades or trades straight chains).

L'expérience a, cependant, montré que ces organes de ventilation ne sont pas à eux seuls de nature à donner entière satisfaction, étant donné que, si elle se présente sous forme de ballon au niveau des organes d'entraînement, la bande risque de s'emmêler autour des rotors puis de se placer irrégulièrement au fond du canal de stockage.Experience has, however, shown that these ventilation members are not in themselves capable of giving complete satisfaction, since, if it is in the form of a balloon at the level of the drive members, the strip risks get tangled around the rotors and then move irregularly to the bottom of the storage channel.

Il est donc impératif d'associer aux organes de ventilation des organes de pincement susceptibles d'aplatir le ballon et de l'étaler sur toute sa largeur.It is therefore imperative to associate with the bodies of ventilation of the pinching members capable of flattening the balloon and spreading it over its entire width.

Selon une autre caractéristique de l'invention, ces organes de pincement sont constitués par deux éléments presseurs qui se font face, définissent entre-eux un canal d'étranglement dans lequel la boucle est prise en sandwich et dont au moins un est monté élastiquement de manière à exercer une pression transversale prédéterminée sur les pièces textiles.According to another characteristic of the invention, these clamping members consist of two pressing elements which face each other, define between them a throttling channel in which the loop is sandwiched and at least one of which is resiliently mounted so as to exert a predetermined transverse pressure on the textile parts.

Les éléments presseurs peuvent, bien entendu être quelconques, sans pour cela sortir du cadre de l'invention, et, par exemple, être constitués par des barres fixes, des rouleaux fous, des plaques, etc...The pressing elements can, of course be any, without departing from the scope of the invention, and, for example, be constituted by fixed bars, idle rollers, plates, etc.

Le ou les éléments presseurs mobiles sont de préférence montés sur un guide équipé d'un ressort de pression réglable, de façon à permettre de régler la pression transversale exercée en fonction des caractéristiques des pièces textiles.The movable pressing element or elements are preferably mounted on a guide equipped with an adjustable pressure spring, so as to allow the transverse pressure exerted to be adjusted as a function of the characteristics of the textile pieces.

Il est, en effet, essentiel de contrôler cette pression de manière à permettre au textile de s'aplatir et de s'épanouir sur toute sa largeur, sans l'écraser sous l'effet d'une pression trop importante.It is, in fact, essential to control this pressure so as to allow the textile to flatten and flourish over its entire width, without crushing it under the effect of excessive pressure.

Cet étalement de la matière permet d'augmenter dans une large mesure la surface d'adhérence textile-rotors, et donc, d'éliminer largement les risques d'emmêlement de la boucle au niveau des organes d'entraînement.This spreading of the material makes it possible to increase to a large extent the surface of textile-rotor adhesion, and therefore, to largely eliminate the risks of tangling of the loop at the level of the drive members.

Les organes de pincement présentent, par ailleurs, l'avantage de permettre aux pièces textiles de perdre une grande partie du bain de teinture préalablement absorbé ; cette action d'"exprimage" se complète au niveau des organes d'entraînement, ce qui a pour effet de rendre la matière textile avide de bain lors de sa chute dans le canal de stockage. Ce principe "dit de l'éponge" favorise les échanges colorant/textile.The pinching members have, moreover, the advantage of allowing the textile pieces to lose a large part of the dye bath previously absorbed; this "expressing" action is completed at the level of the drive members, which has the effect of making the textile material greedy for bath when it falls into the storage channel. This "Sponge" principle promotes dye / textile exchanges.

En outre, et selon une caractéristique préférentielle de l'invention, les organes de pincement coopèrent avec un détecteur de proximité susceptible de détecter la présence d'une surépaisseur et de commander en réponse l'arrêt de la machine.In addition, and according to a preferred characteristic of the invention, the clamping members cooperate with a proximity detector capable of detecting the presence of an excess thickness and of controlling the stopping of the machine in response.

Comme il a déjà été indiqué, il arrive que des surépaisseurs engendrées accidentellement en cours de processus nuisent au résultat final obtenu ou même provoquent un endommagement de la machine ; le détecteur de proximité permet de remédier à cet inconvénient en arrêtant automatiquement la rotation de la boucle dès que la présence d'une surépaisseur dépassant une dimension prédéterminée a été détectée.As already indicated, it sometimes happens that excess thicknesses accidentally generated during the process harm the final result obtained or even cause damage to the machine; the proximity detector overcomes this drawback by automatically stopping the rotation of the loop as soon as the presence of an excess thickness exceeding a predetermined dimension has been detected.

Il est bien entendu, avantageux de pouvoir régler le seuil de sensibilité de ce détecteur en fonction de la nature des produits traités.It is of course advantageous to be able to adjust the sensitivity threshold of this detector as a function of the nature of the products treated.

Le détecteur de proximité peut également être utilisé pour contrôler la mise en oeuvre du processus de teinture en détectant chaque passage de la couture grossière et donc en comptant le nombre de "tours" effectué par chaque pièce textile.The proximity sensor can also be used to control the implementation of the dyeing process by detecting each pass of the coarse seam and therefore counting the number of "turns" made by each textile piece.

Par ailleurs, lors d'une opération de teinture, il est nécessaire de découper de temps à autre des échantillons dans la boucle pour vérifier le déroulement du processus.In addition, during a dyeing operation, it is necessary to cut samples from time to time in the loop to check the progress of the process.

Cette découpe, si elle est effectuée de manière aléatoire, c'est-à-dire n'importe où à l'intérieur des pièces, provoque des trous intolérables dans un travail de qualité.This cutting, if it is done randomly, that is to say anywhere inside the parts, causes intolerable holes in quality work.

Pour remédier à cet inconvénient, il est nécessaire d'effectuer ces découpes, non pas de manière anarchique, mais, en un endroit prédéterminé, de préférence à proximité de la couture grossière ; dans ce but, on a déjà proposé de coudre un élément magnétisé à ce niveau dans la boucle, et d'enregistrer les passages de ce témoin devant un détecteur magnétique qui est coûteux et fragile.To overcome this drawback, it is necessary to make these cuts, not in an anarchic manner, but, in a predetermined location, preferably near the coarse seam; for this purpose, it has already been proposed to sew a magnetized element at this level in the loop, and to record the passages of this witness in front of a magnetic detector which is expensive and fragile.

De plus, cet élément magnétique qui est environ de la taille d'une noisette risque d'être égaré dans la machine en cours de processus, ce qui est là encore source d'inconvénients.In addition, this magnetic element which is about the size of a hazelnut may be lost in the machine during the process, which is again a source of drawbacks.

La présente du détecteur de proximité permet, de manière très simple, d'arrêter la machine au niveau de la couture grossière, et donc de prélever les échantillons à l'endroit idéal.The presence of the proximity sensor makes it very simple to stop the machine at the coarse seam, and therefore to take the samples at the ideal location.

Les caractéristiques de la machine qui fait l'objet de l'invention seront décrites plus en détail en se référant au dessin annexé qui représente une coupe schématique de cette machine. Selon la figure, la machine est destinée à effectuer la teinture de pièces textiles assemblées les unes aux autres par des coutures fines, non représentées, et refermées en une boucle 1 par une couture grossière et en relief 2.The characteristics of the machine which is the subject of the invention will be described in more detail with reference to the attached drawing which represents a schematic section of this machine. According to the figure, the machine is intended for dyeing textile pieces assembled together with fine seams, not shown, and closed in a loop 1 by a coarse and raised seam 2.

La machine est shématiquement constituée par une enceinte 3 reliée à l'extérieur par des orifices d'entrée et de sortie non représentés, et munie, à sa partie inférieure d'un canal de stockage 4 des pièces textiles, dont le fond 5, en forme de cuvette, reçoit un bain de teintureThe machine is shematically constituted by an enclosure 3 connected to the outside by inlet and outlet orifices not shown, and provided, at its lower part with a storage channel 4 for textile parts, the bottom 5 of which bowl-shaped, receives a dye bath

Comme représenté sur la figure, les pièces textiles constituant la boucle 1 se rassemblent en formant des plis par entassement à la partie inférieure du canal de stockage 4.As shown in the figure, the textile pieces constituting the loop 1 come together by forming folds by crowding at the bottom of the storage channel 4.

L'enceinte 3 est, par ailleurs, munie, à sa partie supérieure, d'un ensemble de rotors 6 montés de manière à relever les pièces textiles se trouvant au fond du canal de stockage 4 selon la flèche A et à commander leur rotation en continu à une vitesse prédéterminée.The enclosure 3 is, moreover, provided, at its upper part, with a set of rotors 6 mounted so as to raise the textile pieces located at the bottom of the storage channel 4 according to arrow A and at control their rotation continuously at a predetermined speed.

Les rotors 6 sont formés, chacun, d'un noyau central 7 muni, sur son chant, de lames 8 dont la partie 9 du bord extérieur est souple. Ces rotors correspondent, en fait, à ceux décrits dans le brevet FR 82 14 615 et ne seront, pour cette raison, pas décrits ici plus en détail.The rotors 6 are each formed of a central core 7 provided, on its edge, with blades 8, the part 9 of the outer edge of which is flexible. These rotors correspond, in fact, to those described in patent FR 82 14 615 and will therefore not be described here in more detail.

La figure représente l'exemple de quatre rotors 6 disposés en ligne et dont les pales sont imbriquées (pignonage) ; cette configuration n'a, bien entendu, été choisie qu'à titre d'exemple et ne saurait être considérée comme étant limitative de l'invention.The figure shows the example of four rotors 6 arranged in line and whose blades are nested (pinion); this configuration has, of course, been chosen only by way of example and cannot be considered to be limiting of the invention.

Le rôle de l'ensemble de pales 6 est d'exprimer les pièces textiles afin de leur faire perdre une grande partie du bain de teinture qu'elles ont absorbé et donc de favoriser l'absorption ultérieure de bain lorsqu'elles retombent à la partie inférieure du canal de stockage 4 selon la flèche B. Pour que cette opération puisse être effectuée de manière uniforme et satisfaisante, il est nécessaire que la boucle 1 se positionne de façon correcte au niveau des rotors 6.The role of the set of blades 6 is to express the textile pieces in order to make them lose a large part of the dye bath which they have absorbed and therefore to promote the subsequent absorption of bath when they fall back to the part. lower of the storage channel 4 according to arrow B. For this operation to be able to be carried out in a uniform and satisfactory manner, it is necessary that the loop 1 is positioned correctly at the level of the rotors 6.

A cet effet, et conformément à la figure, les rotors 6 coopèrent à leur partie amont considérée dans le sens de rotation A, B de la boucle 1, avec des moyens d'épanouissement et de positionnement dont le rôle est d'épanouir, de dévriller et de déplisser les pièces textiles de façon à les présenter correctement pour la suite du processus.To this end, and in accordance with the figure, the rotors 6 cooperate at their upstream part considered in the direction of rotation A, B of the loop 1, with development and positioning means whose role is to develop, unwind and unfold the textile pieces so as to present them correctly for the rest of the process.

Ces moyens sont constitués, d'une part, par une buse de ventilation 10 et, d'autre part, par des éléments de pincement 11.These means consist, on the one hand, of a ventilation nozzle 10 and, on the other hand, of gripping elements 11.

Selon la figure, la buse de ventilation 10 est placée directement à la sortie du canal de stockage 4 et est constituée par une tuyère à air alimentée par de l'air interne à la machine ; elle provoque un épanouissement de la boucle 1 en un ballon 12.According to the figure, the ventilation nozzle 10 is placed directly at the outlet of the storage channel 4 and is constituted by an air nozzle supplied with air internal to the machine; it causes the loop 1 to flourish into a balloon 12.

Les éléments de pincement 11 qui sont situés en aval de la buse de ventilation 10 sont, quant à eux, constitués par deux barres 13, 13' qui se font face et dont l'une 13 est fixe tandis que l'autre l3' est soumise à la pression réglable d'un ressort 14. Les barres 13 et l3' définissent entre elles un étranglement dans lequel la boucle 1 se trouve prise en sandwich de manière à aplatir le ballon 12 et à permettre au textile de s'épanouir sur toute sa largeur grâce à la pression transversale F exercée par la barre mobile 13'.The clamping elements 11 which are located downstream of the ventilation nozzle 10 are, in turn, constituted by two bars 13, 13 'which face each other and one of which 13 is fixed while the other 13' is subjected to the adjustable pressure of a spring 14. The bars 13 and 13 ′ define between them a constriction in which the loop 1 is sandwiched so as to flatten the ball 12 and allow the textile to flourish over any its width thanks to the transverse pressure F exerted by the movable bar 13 '.

A la sortie des organes de pincement 11, la boucle 1 se trouve positionnée de manière à présenter une surface d'adhérence maximale sur les rotors 6.At the exit from the clamping members 11, the loop 1 is positioned so as to have a maximum grip surface on the rotors 6.

Les organes de pincement 11 coopèrent, par ailleurs, avec un détecteur de proximité 15 représenté schématiquement sur la figure, susceptible de détecter le passage de la couture grossière 2 pour, d'une part, détecter le nombre de tours effectués par les pièces textiles et donc l'état d'avancement du processus, et, d'autre part, permettre d'arrêter la rotation de la boucle 1 à ce niveau pour découper un échantillon.The pinching members 11 also cooperate with a proximity detector 15 shown diagrammatically in the figure, capable of detecting the passage of the coarse seam 2 in order, on the one hand, to detect the number of turns made by the textile pieces and therefore the progress of the process, and, on the other hand, allow to stop the rotation of the loop 1 at this level to cut a sample.

Le détecteur de proximité 15 peut également détecter le passage d'une surépaisseur accidentelle supérieure à un seuil prédéterminé réglable, et arrêter en réponse la rotation de la boucle 1 de manière à éviter toute perturbation du processus ou tout endommagement de la machine.The proximity detector 15 can also detect the passage of an accidental excess thickness above a predetermined adjustable threshold, and stop in response the rotation of the loop 1 so as to avoid any disturbance of the process or any damage to the machine.
