Description

La présente invention concerne un dispositif et une installation de transfert, notamment entre un poste de stockage et au moins un forme d'un poste de formage ou de couture ou de repassage, de tubes tricotés constitutifs d'articles chaussants, tels que collant, mi-bas, chaussette, chaque tube présentant à une extrémité une pointe et à l'autre extrémité une bande ou ceinture.The present invention relates to a device and a transfer facility, in particular between a storage and at least one form of a forming station or sewing or ironing, knitted tubes constituting footwear, such as tights, knee-high, sock, each tube presenting to a end a tip and at the other end a band or belt.

La fabrication automatique d'articles chaussants à partir de tubes, encore appelés ébauches tubulaires, tricotés sur une machine à tricoter circulaire est mise en oeuvre depuis de nombreuses années comme illustrent les brevets EP-A-0.508.014 et EP-A-0.521.206. La fabrication de tels articles nécessite divers opérations telles que des opérations de tricotage, d'orientation, de fermeture de pointe, de couture, de pose de gousset, etc., l'ordre et le nombre de ces opérations pouvant varier en fonction de la conception de la chaíne de fabrication et du type de produit à fabriquer. Toutefois, indépendamment de la conception de cette chaíne et du type de produit à fabriquer, il demeure une préoccupation constante en matière de réduction du temps de cycle. Une perte de temps importante est notamment notée lors du positionnement du tube sur une forme d'un poste de formage ou de couture ou de repassage. En effet, le positionnement doit s'opérer de manière à ne pas ralentir les opérations ultérieures effectuées sur le poste. A cet effet, les ébauches sont pré-positionné, en effectuant en particulier le positionnement axial de la pointe, de la bande ou ceinture et de la démarcation du tube sur la forme; ce positionnement en rotation étant en particulier nécessaire pour des tubes asymétriques ou en présence de motifs sur les tubes en vue d'un positionnement relatif et précis de deux tubes entre eux, ces tubes étant destinés, après assemblage, à constituer un article chaussant. Ces opérations de transfert sont effectuées jusqu'à présent au moyen d'un organe de transfert constitué d'une tôle pliée affectant la forme générale un profilée parallélépipédique comme illustre en particulier le brevet EP A-0.508.014. Cet organe de transfert génère une tension importante de l'ébauche tubulaire sur la totalité de sa longueur provoquant un endommagement de la pointe du tube, cette pointe étant inapte a supporter une tension aussi importante que la bande ou ceinture du tube. Par ailleurs, un tel organe de transfert doit à chaque fois être adapté au dimensions des formes des postes adjacents. Enfin, il n'existe pas de possibilité au moyen d'un tel organe de transfert d'assurer une orientation en rotation du tube sur ledit organe.Automatic manufacture of footwear from tubes, also called tubular blanks, knitted on a circular knitting machine is put implemented for many years as illustrate EP-A-0,508,014 and EP-A-0,521,206. The manufacture of such articles requires various operations such as knitting operations, orientation, peak closure, sewing, gusset, etc., the order and number of these operations may vary depending on the design of the production line and the type of product to manufacture. However, regardless of the design of this chain and the type of product to be manufactured, it remains a constant concern reduction of the cycle time. A waste of time important is especially noted when positioning tube on a form of a forming station or sewing or ironing. Indeed, the positioning must be done in such a way as not to slow down subsequent operations performed on the item. In this Indeed, the drafts are pre-positioned, by performing particular the axial positioning of the tip, the band or belt and the demarcation of the tube on the form; this positioning in rotation being in particular need for asymmetrical tubes or in the presence of patterns on the tubes for a Relative and precise positioning of two tubes between they, these tubes being intended, after assembly, to constitute an article of footwear. These operations transfer are carried out so far by means of a transfer member consisting of a folded sheet affecting the general shape a profiled parallelepipedic as illustrates in particular the EP Patent No. 0,508,014. This transfer organ generates a significant tension of the tubular blank on the entire length causing damage to the the point of the tube, this point being unfit for withstand a voltage as high as the band or belt of the tube. Moreover, such a body of transfer must each time be adapted to the dimensions forms of adjacent posts. Finally, there is no possibility by means of such a body of transfer to ensure rotational orientation of the tube on said organ.

Un but de la présente invention est de proposer un dispositif et une installation de transfert du type précité dont les conceptions permettent de préserver la pointe du tube en limitant la tension exercée sur cette dernière par comparaison à la tension exercée sur la bande ou ceinture du tube.An object of the present invention is to propose a device and a transfer facility of the type mentioned above, the designs of which preserve the tip of the tube by limiting the tension exerted on this last in comparison with the tension exerted on the band or belt of the tube.

Un autre but de la présente invention est de proposer un dispositif et une installation de transfert du type précité dont les conceptions permettent de s'adapter à des dimensions variables de forme, l'opération de déchargement du tube sur la forme pouvant en outre permettre un défripage du tube.Another object of the present invention is to propose a device and a transfer facility of the type aforesaid whose designs allow to adapt to variable dimensions of shape, the operation of unloading of the tube on the shape allow deflection of the tube.

Un autre but de la présente invention est de proposer un dispositif et une installation de transfert du type précité dont les conceptions permettent un positionnement axiale et en rotation du tube sur le dispositif de transfert.
Un autre but de la présente invention est de proposer un dispositif de transfert compact susceptible de supporter des cadences de fabrication particulièrement élevées.Another object of the present invention is to provide a device and a transfer installation of the aforementioned type whose designs allow axial and rotational positioning of the tube on the transfer device.
Another object of the present invention is to provide a compact transfer device capable of withstanding particularly high production rates.

A cet effet, l'invention a pour objet un dispositif de transfert, notamment entre un poste de stockage et au moins une forme d'un poste de formage ou de couture ou de repassage, de tubes tricotés constitutifs d'articles chaussants, tels que collant, mi-bas, chaussette, chaque tube présentant à une extrémité une pointe et à l'autre extrémité une bande ou ceinture, dispositif caractérisé en ce qu'il est constitué d'au moins une paire, de préférence au moins deux paires, de broches à disposition parallèle sur au moins une partie de leur longueur, les broches d'une paire de broches étant des broches contre-coudées contrarotatives pour présenter, lors de leur entraínement en rotation , une portion à écartement sensiblement constant entre lesdites broches et une portion à écartement variable de manière à exercer, sur l'élément tubulaire, une tension variable aidant au chargement sur broches, au positionnement de la ponte et de la ceinture sur broches, et au déchargement de broches.For this purpose, the subject of the invention is a device for transfer, in particular between a storage station and least one form of a forming or sewing station or ironing, knitted tubes constituting articles footwear, such as pantyhose, knee-high, sock, each tube having at one end a point and the other end a band or belt, device characterized in that it consists of at least one pair, preferably at least two pairs, of pins parallel arrangement on at least part of their length, the pins of a pair of pins being counter-bent counter-bent pins to present, during their training in rotation, a portion of substantially constant spacing between said pins and a variable gauge portion so as to exert, on the tubular element, a variable tension assisting with pin loading, positioning spawning and belt on pins, and at pin unloading.

La conception des broches contre-coudées, c'est-à-dire coudées au moins deux fois permet ainsi, lors le leur entraínement en rotation, de disposer d'une part d'une première portion des broches destinée à recevoir la partie de la pointe d'un tube enfilé sur la broche dont l'écartement est maintenu sensiblement constant d'une position écartée à une position rapprochée des broches, d'autre part d'une autre portion des broches lors d'un rapprochement ou d'un écartement des broches réalisée à écartement variable de manière à exercer sur l'élément tubulaire, en particulier au niveau de la partie bande ou ceinture de cet élément, une tension variable à l'intérieur d'une plage d'amplitude variable de manière à aider au chargement sur broche, au positionnement de la ceinture sur la broche et au déchargement des broches. Par ailleurs, une telle conception des broches facilite le déchargement du tube sur la forme cela sera décrit ci-après. Enfin, la conception d'un tel dispositif de transfert est simplifié puisqu'un seul mécanisme d'entraínement en rotation est nécessaire pour permettre l'entraínement en rotation des deux broches contrarotatives.The design of the pins bent, that is to say bends at least twice so allows, when the rotational drive, to have on the one hand a first portion of the pins for receiving the part of the tip of a tube threaded on the spindle the spacing is kept substantially constant by one position spaced at a close position of the pins, on the other hand another portion of the pins during a approximation or spacing of the pins realized variable gauge so as to exert on the tubular element, especially at the level of the band or belt part of this element, a tension variable within a range of variable amplitude in order to assist with spindle loading, positioning of the belt on the spindle and unloading the pins. Moreover, such pin design facilitates unloading of the tube on the form this will be described below. Finally, design of such a transfer device is simplified since only one training mechanism rotation is necessary to allow the training in rotation of the two counter-rotating pins.

L'invention a encore pour objet une installation de transfert, entre un poste de stockage et au moins une forme d'un poste de formage ou de couture ou de repassage, de tubes tricotés constitutifs d'articles chaussants, tels que collant, mi-bas, chaussette, chaque tube présentant à une extrémité une pointe et à l'autre extrémité une bande ou ceinture, cette installation étant caractérisée en ce qu'elle est constituée d'au moins un, de préférence une pluralité de dispositif de transfert à broches du type précité, chaque dispositif de transfert étant déplaçable par l'intermédiaire d'un dispositif approprié tel qu'un carrousel de manière à coopérer, au cours de son déplacement, avec une pluralité de postes, au moins une partie de ces postes étant équipés de chariot(s) muni(s) d'organes de friction ou de pincement susceptibles de venir en contact avec les tubes pour positionner axialement au moins la ceinture dudit tube sur lesdites broches, et/ou d'organes de mise en rotation d'une portion de broches pour obtenir une orientation radiale des tubes tricotés sur les broches. L'invention sera bien comprise à la lecture de la description suivante d'exemples de réalisation, en référence aux dessins annexés dans lesquels :

  • les figures 5A à 5D représentent de manière schématique les différentes positions susceptibles d'être occupées par une paire de broches lors d'un cycle de transfert d'un tube tricoté.
The invention also relates to a transfer facility, between a storage station and at least one form of a forming or sewing station or ironing, knitted tubes constituting footwear, such as tacky, half sock, each tube having at one end a tip and at the other end a band or belt, this installation being characterized in that it consists of at least one, preferably a plurality of pin transfer device of the aforementioned type, each transfer device being movable by means of an appropriate device such as a carousel so as to cooperate, during its movement, with a plurality of stations, at least a portion of these stations being equipped carriage (s) provided with friction members or pinching members capable of coming into contact with the tubes for axially positioning at least the belt of said tube on said pins, and / or rotating a portion of pins to obtain a radial orientation of the knitted tubes on the pins. The invention will be better understood on reading the following description of exemplary embodiments, with reference to the appended drawings in which:
  • FIG. 1 represents a side view of a transfer installation according to the invention:
  • FIG. 2 represents a view from above of the transfer device in the vicinity of the tube storage station with a view to loading a tube on the transfer device;

Comme mentionnée ci-dessus, le dispositif et l'installation, objets de l'invention, sont destinés à permettre le transfert de tubes 1 tricotés constitutifs d'articles chaussants, tels que collant, mi-bas, chaussette, notamment entre un poste P de stockage et au moins une forme F1 d'un poste F de formage ou de couture ou de repassage desdits tubes. Ce poste P de stockage peut affecter un grand nombre de formes. Dans l'exemple représenté, ce poste P de stockage est constitué par une boíte d'ouverture dont le détail de réalisation est plus particulièrement décrit dans le brevet EP-A-0.508.014. Les tubes 1 sont amenés à cette boíte d'ouverture après avoir subi une opération de prélèvement en vrac dans un récipient et une étape d'orientation de manière à assurer un chargement du tube 1 sur le dispositif de transfert pointe 1A en avant du tube 1.As mentioned above, the device and installation, objects of the invention, are intended for allow the transfer of constituent knitted tubes 1 footwear, such as tights, knee highs, sock, in particular between a storage station P and at least one form F1 of a forming station F or sewing or ironing said tubes. This post P of storage can affect a lot of forms. In the example shown, this storage station P is constituted by a box of opening whose detail of realization is more particularly described in the EP-A-0,508,014. The tubes 1 are brought to this box of opening after having undergone an operation of Bulk sampling in a container and a step orientation to ensure loading of the tube 1 on the transfer device tip 1A in before the tube 1.

Le tube 1 ainsi orienté pointe 1A en avant doit être transféré par exemple sur une forme F1 se présentant généralement sous forme d'une pince incorporée à un poste F dont les fonctions peuvent être diverses. Ainsi, ce poste F peut constituer indifféremment un poste de formage ou de couture ou de repassage ou de fermeture des pointes du tube. Il est nécessaire qu'au cours de ce transfert le tube 1 soit soumis à des étapes de positionnement de manière à être transféré en une position prédéterminée toujours identique sur la forme F1 pour permettre une réalisation optimisée des opérations sur ce poste F.The tube 1 thus oriented tip 1A forward must be transferred for example to an F1 form presenting itself generally in the form of a clip incorporated into a station F whose functions can be various. Thus, this station F can constitute indifferently a forming or sewing or ironing station or closing of the tips of the tube. It is necessary that during this transfer the tube 1 is submitted to positioning steps so as to be transferred in a predetermined position always the same on the F1 form to allow optimized realization of operations on this item F.

De manière caractéristique à l'invention, le transfert entre ces deux postes s'effectue au moyen d'in dispositif de transfert constitué d'au moins de broches 2 à disposition parallèle sur au moins une partie de leur longueur. La figure 4 illustre, en vue de dessus, la forme générale des broches 2. De préférence, un tel dispositif de transfert comporte deux paires de broches, chaque paire de broches étant destinée à recevoir un tube enfilé sur lesdites broches de la paire de broches. Comme l'illustre la figure 4, les broches d'une paire de broches 2 sont des broches contre-coudées au moins deux fois. Les coudes ont respectivement été représentés en 3A et 3B à la figure 4. Ces broches sont par ailleurs des broches rotatives entraínées en rotation de manière contrarotative. Elles présentent ainsi, lors de leur entraínement en rotation, une portion 2A à écartement sensiblement constant entre lesdites broches et une portion 2B à écartement variable entre lesdites broches. La portion 2A à écartement sensiblement constant des broches est destinée à recevoir la partie pointe 1A de l'ébauche 1 tandis que la portion 2B à écartement variable des broches est destinée à recevoir la partie bande ou ceinture 1B du tube 1. L'extrémité libre des broches est représentée en 2C. L'extrémité des broches destinée à être raccordée à un mécanisme d'entraínement en rotation incorporé à un porte-broches est représentée en 2D à la figure 4. Le mécanisme d'entraínement en rotation des broches, représenté en 9 aux figures, est agencé pour permettre un déplacement cinématiquement solidaire des broches. A cet effet, un seul mécanisme moteur d'entraínement peut être nécessaire, un dispositif à engrenage pouvant assurer la liaison d'une broche à une autre. Les broches 2 d'une telle paire de broches sont ainsi susceptibles de passer d'une position rapprochée, représentée en pointillés à la figure 4, à une position écartée représentée en traits plein à la figure 4 en appliquant ainsi une tension variable au tube 1 enfilé sur les broches. Cette tension variable permet d'aider au chargement du tube sur les broches, au positionnement de la pointe 1A et de la ceinture 1B sur les broches et au déchargement des broches 2 comme l'illustrera la description ci-après. Comme le montre à nouveau cette figure 4, chaque broche 2 est un broche tubulaire. La partie de la broche s'étendant entre une extrémité 2C libre et une portion 3A, 3B contre-coudée est montée libre à rotation, le reste de la broche 2 étant à rotation commandée au moyen du mécanisme 9 d'entraínement en rotation. Pour permettre un montage fou de la partie de la broche s'étendant entre le coude 3B et l'extrémité libre 2C, il peut être prévu, le coude 3B et l'extrémité libre 2C, il peut être prévu, dans le corps de la broche, par exemple une douille à aiguilles. La fonction de ce montage libre à rotation sera décrite ci-après. Chaque paire de broches 2 ainsi réalisée est montée sur une porte-broche 4 incluant un mécanisme 9 d'entraínement à contra-rotation commandée des broches 2 dans le sens d'un rapprochement ou d'un écartement des broches 2 comme mentionné ci dessus. Dans les exemples représentés, ce porte-broche 4 est constitué d'un chariot animé d'un mouvement de va-et-vient. Ce chariot est monté de préférence sur un carrousel 5, pour le transfert des éléments 1 tubulaires tricotés de poste à poste. Comme l'illustre la description ci-dessus, il peut être considéré que les broches 2 d'une paire de broches affectent respectivement la forme générale de manivelle.Characteristically to the invention, the transfer between these two positions is effected by means of transfer device consisting of at least pins 2 parallel arrangement on at least a part of their length. FIG. 4 illustrates, in a view from above, the general shape of the pins 2. Preferably, such a transfer device has two pairs of pins, each pair of pins being intended for receive a tube threaded on said pins of the pair of pins. As illustrated in Figure 4, pins of a pair of pins 2 are pins bent at least twice. Elbows have respectively shown in 3A and 3B in the figure 4. These pins are also rotating pins rotated in a contra-rotating manner. They thus present, during their training in rotation, a portion 2A substantially spaced constant between said pins and a portion 2B to variable spacing between said pins. The part 2A at substantially constant spacing of the pins is intended to receive the tip portion 1A of the blank 1 while variable-gauge portion 2B pins is intended to receive the band portion or tube 1B belt 1. The free end of the pins is represented in 2C. The end of the pins intended to be connected to a drive mechanism in rotation incorporated in a pin carrier is shown in 2D in Figure 4. The drive mechanism in rotation of the pins, shown at 9 in the figures, is arranged to allow movement kinematically secured to the pins. For this purpose, a single mechanism motor drive may be required, a gear device capable of providing the connection of a pin to another. The pins 2 of such a pair of pins are thus likely to go from one close position, shown in dashed line at FIG. 4, at a separated position represented in lines full in Figure 4 thus applying a voltage variable to tube 1 threaded on the pins. This variable voltage helps to load the tube on the pins, to the positioning of the tip 1A and belt 1B on the pins and unloading pins 2 as will be illustrated in the description below. As shown again in Figure 4, each pin 2 is a tubular pin. The part of the pin extending between a free end 2C and a portion 3A, 3B against-bent is mounted free to rotation, the rest of the spindle 2 being rotated commanded by means of the training mechanism 9 rotation. To allow crazy editing of the game the spindle extending between the elbow 3B and the end free 2C, it can be expected, the elbow 3B and the free end 2C, it can be provided in the body pin, for example a needle socket. The function of this free rotational assembly will be described below. Each pair of pins 2 thus produced is mounted on a spindle holder 4 including a mechanism 9 controlled contra-rotation drive of the pins 2 in the direction of approximation or spacing pins 2 as mentioned above. In the examples shown, this spindle holder 4 consists of a cart moving back and forth. This trolley is preferably mounted on a carousel 5, for the transfer of the knitted tubular elements 1 of peer-to-peer As the description above illustrates, it can be considered that the pins 2 of a pair of pins respectively affect the shape general crank.

Dans le cadre d'une installation de transfert conforme à celle représentée à la figure 1, de tels dispositifs de transfert présentent un grand nombre d'avantages. L'installation de transfert est ici constituée d'une pluralité de dispositifs de transfert à broche 2, en l'occurrence quatre dispositifs de transfert, chaque dispositif de transfert étant ici lui-même constitué de deux paire de broches. Chaque dispositif de transfert est déplaçable par l'intermédiaire d'un dispositif approprié tel qu'un carrousel 5 de manière à coopérer, au cours de son déplacement, avec une pluralité de postes représentés en P, P1, F, E. Dans les exemples représentés, le poste P correspond au poste de chargement en parallèle de deux tubes 1 enfilés respectivement sur une paire de broches 2 du dispositif de transfert. Ce dispositif de transfert est ensuite déplacé par l'intermédiaire du carrousel 5 à un poste P1 dit poste de positionnement. A ce poste, en particulier la ceinture 1B et la démarcation du tube 1 sont positionnées axialement sur chaque paire de broches 2 du dispositif de transfert. De même, si nécessaire, une orientation en rotation du tube 1 est opérée sur la paire de broches de manière par exemple à positionner des motifs d'un tube en regard des motifs d'un autre tube ou dans le cas de tube asymétrique à positionner correctement le tube sur la paire de broches. Ce dispositif de transfert est ensuite déplacé par le carrousel jusqu'à un poste F dit poste de déchargement du tube sur une forme F1 qui peut constituer l'un des éléments d'un poste de couture, de formage, de repassage, de fermeture de pointe ou autre. Au cours de ce déchargement, du fait de la conception des broches, on peut constater un défripage des tubes. Enfin, en cas d'anomalies constatées sur le tube, le tube peut être évacué du dispositif de transfert au niveau du poste E appelé poste d'évacuation. Ce poste d'évacuation a donc pour fonction uniquement d'évacuer les tubes défaillants.As part of a compliant transfer installation to that shown in Figure 1, such devices transfer have a large number of advantages. The transfer facility here consists of a plurality of pin transfer devices 2, in the occurrence four transfer devices, each transfer device being here itself constituted of two pair of pins. Each transfer device is movable via a device such as a carousel 5 so as to cooperate, during his travels, with a plurality of positions represented in P, P1, F, E. In the examples represented, position P corresponds to the position of parallel loading of two 1-threaded tubes respectively on a pair of pins 2 of the device transfer. This transfer device is then moved through the carousel 5 to a post P1 says positioning station. In this post, especially the belt 1B and the demarcation of the tube 1 are positioned axially on each pair of pins 2 of the transfer device. Similarly, if necessary, a rotational orientation of the tube 1 is operated on the pair of pins so for example to position patterns of a tube next to the patterns from another tube or in the case of asymmetric tube to correctly position the tube on the pair of pin. This transfer device is then moved by the carousel to a post F said post of unloading the tube on a F1 shape that can constitute one of the elements of a sewing forming, ironing, tip closing or other. During this unloading, due to the design pins, we can see a defibrillation tubes. Finally, in the event of anomalies found on the tube, the tube can be evacuated from the transfer device to level of station E called evacuation station. This post The sole purpose of evacuation is therefore to evacuate the faulty tubes.

Comme l'illustrera la description ci-après, au moins une partie P, P1 de ces postes sont équipés de chariot (s) 6 muni (s) d'organes 7 de friction ou de pincement susceptibles de venir en contact avec les tubes 1 enfilés sur le broches 2 pour positionner axialement au moins la ceinture 1B du tube 1 sur lesdites broches 2, et / ou d'organes 8 de mise en rotation d'une portion de broches 2 pour obtenir une orientation radiale des tubes 1 tricotés sur les broches 2.As will be illustrated by the description below, at least a part P, P1 of these stations are equipped with trolley (s) 6 provided with 7 friction or pinch members likely to come in contact with the tubes 1 threaded onto pin 2 to position axially at minus the belt 1B of the tube 1 on said pins 2, and / or organs 8 for rotating a portion of pins 2 to obtain a radial orientation of the 1 knitted tubes on the pins 2.

Comme le montre ainsi la figure 1, les dispositifs de transfert, constitués à chaque fois de deux paires de broches 2, sont montés sur un carrousel 5 commun à l'ensemble des dispositifs de transfert. Le carrousel 5 amène donc, au cours d'un tour de rotation, cheque dispositif de transfert devant les quatre postes précités. Lorsque le dispositif de transfert est positionné au voisinage du poste P, encore appelé poste de chargement du ou des tube (s) ou poste de stockage en vrac des tubes, il peut être procédé au chargement de tube (s) pointe 1A en avant sur le dispositif de transfert. Du fait que l'installation possède, pour un dispositif de transfert, deux paires de broches positionnées côte à côte, deux tubes 1 sont transférés simultanément. L'opération de transfert peut s'effectuer par l'intermédiaire des chariots 6 équipés d'organes 7 de friction constitués, dans l'exemple représenté, par des rouleaux. Ces chariots 6 se déplacent parallèlement aux broches 2 de manière à venir en contact de tube 1 et permettre à ces derniers d'être enfilés sur une paires de broches 2. Pour faciliter cette opération de chargement, la paire de broches 2 est amenée au moyen d'un chariot 4 constituant le porte-broches au voisinage immédiat du poste P. L'opération de chargement peut alors commencer. Lorsque le chariot 4 est en fin de course aller et que le chargement est presque terminé, les broches 2 sont déplacées en rotation pour occuper une position dite intermédiaire représentée à la figure 5B. Cette ouverture intermédiaire permet de finir d'enfiler le tube 1 sur une paire de broches 2. Cette ouverture intermédiaire permet en outre de charger le tube 1 sans le vriller. Du fait que la pointe 1A est introduite la première sur le dispositif de transfert et du fait de la conception des broches 2 du dispositif de transfert, on constate que l'ouverture des broches ne débute que lorsque la pointe est positionnée au voisinage de la portion 2A des broches qui, au cours de cet entraínement en rotation des broches, sera maintenue à écartement sensiblement constant. Il n'en résulte aucun endommagement de la pointe 1A du tube 1 au cours de cet écartement des broches 2. La figure 2 illustre le positionnement du chariot 6 en fin de course aller. Le positionnement axial du tube 1, en particulier de la ceinture 1B du tube 1 sur les broches 2, peut être détecté au moyen de cellules appropriées. Une fois cette opération de chargement terminée, le porte-broches 4, constitué ici par un chariot, se déplace en direction du carrousel 5 pour ramener le dispositif de transfert en position initiale. Le carrousel 5 peut alors entraíner le dispositif de transfert sur un quart de tour et amener ce dispositif de transfert au voisinage du poste P1, dit poste de positionnement.As shown in Figure 1, transfer, each consisting of two pairs of pins 2, are mounted on a carousel 5 common to the set of transfer devices. The carousel 5 bring, during a turn, check transfer device in front of the four posts supra. When the transfer device is positioned in the vicinity of the post P, also called post loading the tube (s) or storage station bulk of the tubes, it can be loaded of tube (s) point 1A forward on the device of transfer. Because the installation has, for one transfer device, two pairs of pins positioned side by side, two tubes 1 are transferred simultaneously. The transfer operation can to be carried out by means of the carriages 6 equipped of friction members 7 formed in the example represented by rollers. These carriages 6 are move parallel to pins 2 so as to come into contact with tube 1 and allow them to be strung on a pair of pins 2. To facilitate this loading operation, the pair of pin 2 is brought by means of a carriage 4 constituting the pin holder in the immediate vicinity of the P. The loading operation can then be to start. When the carriage 4 is at the end of the race to go and that the loading is almost finished, the pins 2 are rotated to occupy a said intermediate position shown in Figure 5B. This intermediate opening allows you to finish putting on the tube 1 on a pair of pins 2. This opening intermediate allows further to charge the tube 1 without twist it. Since the tip 1A is introduced the first on the transfer device and the fact of the design of pins 2 of the transfer device, we note that the opening of the pins starts only when the tip is positioned in the vicinity of the portion 2A of the pins which, during this drive in rotation of the pins, will be maintained at substantially constant spacing. It does not result in any damage to the tip 1A of the tube 1 during this pin spacing 2. Figure 2 illustrates the positioning of the carriage 6 at the end of the race. The axial positioning of the tube 1, in particular of the 1B tube 1 belt on pins 2, can be detected by means of appropriate cells. Once this loading operation completed, the pin holder 4, constituted here by a carriage, moves in direction of the carousel 5 to bring back the device transfer to initial position. The carousel 5 can then drive the transfer device on a quarter turn and bring this transfer device to neighborhood P1 post, said positioning station.

A ce poste, il est procédé à un positionnement axial précis du tube 1 sur les broches 2. L'opération de positionnement de la ceinture ou bande 1B du tube 1 sur les broches 2 s'effectue à nouveau au moyen d'un chariot 6 (figure 3) déplaçable axialement de long des broches 2. Ce chariot 6 est muni d'organes 7 de pincement venant à contact contre le tube enfilé sur les broches pour assurer ce positionnement. Il peut être prévu, comme l'illustre la figure 3, un jeu de cellules optiques escamotables pour aider à la réalisation de ce positionnement. Ces cellules escamotables s'escamotent lors de la rotation du carrousel 5. Ensuite, le porte-broches, affectant la forme d'un chariot 4, est déplacé pour permettre aux broches du dispositif de transfert de venir se positionner à l'intérieur de paliers 8 moteurs incorporés au poste de positionnement. Au cours de l'entraínement en rotation de ces paliers 8, on constate l'entraínement en rotation des parties libres des broches permettant une orientation en rotation du tube 1 sur les broches. Cette opération pourra être assistée au moyen de dispositifs de détection optique tels que des cellules aptes à détecter des repères disposées notamment sur les tubes 1.At this position, axial positioning is carried out accurate of the tube 1 on the pins 2. The operation of positioning of the belt or band 1B of the tube 1 on pins 2 is done again by means of a carriage 6 (FIG. 3) movable axially along the 2. This carriage 6 is provided with organs 7 of pinching coming into contact against the tube threaded on the pins to ensure this positioning. he can be shown, as illustrated in Figure 3, a game of retractable optical cells to help the realization of this positioning. These cells retractable ones retract during the rotation of the carousel 5. Then the pin carrier, affecting the a carriage 4, is moved to allow pins of the transfer device to come to position inside bearings 8 motors incorporated in the positioning station. During the drive in rotation of these bearings 8, one note the rotational drive of the free parts pins for rotational orientation of the tube 1 on the pins. This operation can be assisted by means of optical detection devices such as cells able to detect markers arranged in particular on the tubes 1.

Une fois cette étape de positionnement terminée, le chariot 4 porte-broche est ramené à sa position initiale. Les broches 2 peuvent alors être écartées pour exercer une tension maximale sur le tube 1 comme l'illustre la figure 5C. De manière analogue à ce qui a été décrit pour le poste de chargement, le carrousel 5 opère un nouveau quart de tour pour amener le dispositif de transfert au voisinage du poste de chargement correspondant au déchargement du tube 1 sur une forme F d'un poste quelconque tel qu'un poste de couture, de formage, de repassage, de fermeture de pointe ou autre. A nouveau la conception du dispositif de transfert s'avère particulièrement intéressante pour procéder à cette opération de déchargement. En effet, comme l'illustre la figure 5D, les broches d'une paire de broches peuvent être positionnées de part et d'autre de la forme F pour ensuite être rapprochées par entraínement en rotation comme l'illustre la figure 5D. Lorsqu'elle sont revenues à leur position initiale correspondant à la figure 5A, il suffit alors de retirer ces broches par déplacement en translation du chariot 4 en direction du carrousel 5, le tube 1 venant alors se positionner automatiquement sur la forme F. On constate que ce mouvement en arc de cercle des broches au cours de leur passage d'une position écartées à une position rapprochée ou inversement facilite en outre le défripage des tubes. Cette opération de déchargement peut être facilitée par l'intermédiaire de dispositifs de soufflage qui sont amenés à l'intérieur des broches pour dégager les pointes. Une fois l'opération de déchargement terminée, au cours du recul des broches commandé par le porte-broches 4, les tubes 1 sont donc soufflés pour aider à leur dépose sur la forme F1. Le chariot 4 porte-broches est à nouveau ramené en position de départ. Le carrousel peut alors effectuer à nouveau un quart de tour pour amener le dispositif de transfert au voisinage du poste E d'évacuation. Ce poste n'est actif que lorsqu'un tube à été mal chargé ou mal positionné. Il peut alors être évacué au niveau de ce poste. Dans ce cas, les broches n'ont pas été rapprochées au poste de déchargement. Il en résulte que ces broches sont encore en position écartée. Il suffit alors de rapprocher les broches pour obtenir par gravité une évacuation du tube 1 des broches 2. Ces tubes 1 sont alors aspirés par une boíte d'aspiration et retombent dans un récipient de stockage. Une nouvelle opération de transfert peut alors commencer par amenée du dispositif de transfert au poste de chargement. Un nouveau cycle de transfert recommence. Grâce à la conception du dispositif de transfert, ce transfert peut s'effectuer en quelques secondes tout en assurant un positionnement précis du tube sur la forme F du poste de formage ou de repassage ou de couture. L'ensemble de ces opérations peuvent s'effectuer dans un espace extrêmement réduit du fait de la compacité de l'installation.Once this positioning step is complete, the carriage 4 pin holder is brought back to its position initial. Pins 2 can then be discarded to exert maximum tension on tube 1 as illustrates it in FIG. 5C. In a similar way to what been described for the loading station, the carousel 5 operates a new quarter turn to bring the transfer device in the vicinity of the loading corresponding to the unloading of the tube 1 on a form F of any position such as a post of sewing, forming, ironing, closing tip or other. Again the design of the device is particularly interesting for proceed with this unloading operation. Indeed, as shown in Figure 5D, the pins of a pair pins can be positioned on either side of the form F to then be approximated by rotational drive as shown in Figure 5D. When they have returned to their original position corresponding to Figure 5A, it is then sufficient to remove these pins by translational movement of the trolley 4 towards the carousel 5, the tube 1 coming then position yourself automatically on the form F. On finds that this movement in an arc of circle of the pins during their shift from a position apart to a close position or conversely facilitates further wrinkling of the tubes. This unloading operation can be facilitated via devices blowing which are brought inside the pins to clear the tips. Once the operation of unloading completed, during the retreat of the pins controlled by the pin holder 4, the tubes 1 are therefore blown to help their removal on the F1 form. The carriage 4 pin holder is again brought back into starting position. The carousel can then perform again a quarter turn to bring the device to transfer to the vicinity of evacuation station E. This post is active only when a tube has been incorrectly loaded or poorly positioned. It can then be evacuated of this post. In this case, the pins were not near the unloading station. It follows that these pins are still in the separated position. It is enough then bring the pins together to get by gravity an evacuation of the tube 1 of the pins 2. These tubes 1 are then sucked by a suction box and fall back into a storage container. A new transfer operation can then begin by bringing the transfer device to the loading. A new transfer cycle begins again. Thanks to the design of the transfer device, this transfer can be done in a few seconds while ensuring a precise positioning of the tube on the form F of the forming or ironing or sewing station. All of these operations can be performed in an extremely small space due to the compactness of installation.
