Description

La présente invention concerne la manutention automatique de pièces, notamment au cours du déroulement d'une fabrication, lorsque les pièces qui proviennent d'un poste de traitement dans une direction et une position données doivent être présentées dans un second poste de traitement dans une direction et une position prédéterminées différentes de celles qu'elles possèdent dans le premier poste. L'invention a trait de manière préférentielle à la confection d'articles textiles, au cours de laquelle les pièces textiles, qui sont des parties unitaires de l'article, passent d'un poste à un autre pour subir toutes les opération d'ourlage, pliage, assemblage, couture... qui donneront naissance à l'article entièrement cbnfectionné.The present invention relates to the automatic handling of parts, in particular during the course of a production, when the parts which come from a processing station in a given direction and a position must be presented in a second processing station in a direction and a predetermined position different from those they have in the first post. The invention relates preferably to the manufacture of textile articles, during which the textile pieces, which are unit parts of the article, pass from one station to another to undergo all the hemming operations. , folding, assembling, sewing ... which will give birth to the fully perfected article.

On connait déjà, par la demande de brevet français N° 79. 13658, un procédé et une installation pour amener à un second poste, dans une position et orientation fixes prédéterminées, une pièce, notamment une pièce souple en feuille telle qu'une étoffe, qui se trouve dans un premier poste dans une position approximative. Le fait que la pièce se trouve au premier poste dans une position approximative nécessite l'utilisation de moyens de repérage de la position de la pièce par rapport à un repère fixe, en sorte que les moyens de transfert se placent sur la pièce en fonction des informations transmises par les moyens de repérage et transfèrent celle-ci au second poste dans la position et orientation fixes prédéterminées.We already know, from French patent application No. 79. 13658, a method and an installation for bringing to a second station, in a predetermined fixed position and orientation, a piece, in particular a flexible sheet piece such as a fabric. , which is in a first position in an approximate position. The fact that the part is at the first station in an approximate position requires the use of means for locating the position of the part with respect to a fixed mark, so that the transfer means are placed on the part according to the information transmitted by the tracking means and transfer it to the second station in the predetermined fixed position and orientation.

L'inconvénient majeur des techniques connues, comme celle décrite dans la demande précitée, réside dans la succession d'opérations indépendantes les unes des autres qui augmente le temps nécessaire à l'accomplissement d'un cycle complet. Or on a trouvé , et c'est l'objet de l'invention, un procédé de transfert et de positionnement qui ne nécessite quasiment aucun arrêt de la pièce depuis le premier poste d'où ladite pièce est alimentée par glissement sur une surface plane grâce à un premier moyen de transfert dans une direction et une position données jusqu'au second poste où ladite pièce est menée par glissement sur une surface plane dans une direction et une position prédéterminées, différentes de celles qu'elle possède au premier poste. Le procédé selon l'invention est caractérisé par les étapes suivantes :

  • a. lorsque la pièce atteint un premier emplacement donné, elle est dégagée du premier moyen de transfert et presque simultanément prise en charge par un moyen dit de transfert et de positionnement, ces deux actions presque simultanées étant rendues possibles grâce à l'abaissement de la surface de glissement,
  • b. elle est ensuite transférée vers le second poste par le moyen de transfert et de positionnement, qui assure à la fois son transfert et son changement de position,
  • c. lorsque la pièce atteint un second emplacement donné où elle a la position prédéterminée, elle est dégagée du moyen de transfert et de positionnement et simultanément prise en charge par un second moyen de transfert qui la transfère au second poste dans la direction et la position prédéterminées, grâce au relèvement de la surface de glissement.
The major drawback of known techniques, such as that described in the aforementioned application, lies in the succession of operations independent of each other which increases the time necessary for the completion of a complete cycle. Now we have found, and this is the object of the invention, a transfer and positioning process which requires almost no stopping of the part from the first station from which said part is fed by sliding on a flat surface. thanks to a first means of transfer in a direc tion and a position given up to the second station where said piece is led by sliding on a flat surface in a predetermined direction and position, different from those it has at the first station. The method according to the invention is characterized by the following steps:
  • at. when the part reaches a first given location, it is released from the first transfer means and almost simultaneously supported by a so-called transfer and positioning means, these two almost simultaneous actions being made possible by the lowering of the surface of slip,
  • b. it is then transferred to the second station by the transfer and positioning means, which ensures both its transfer and its change of position,
  • vs. when the part reaches a second given location where it has the predetermined position, it is released from the transfer and positioning means and simultaneously taken up by a second transfer means which transfers it to the second station in the predetermined direction and position, thanks to the raising of the sliding surface.

Ainsi le déroulement de toutes les étapes du procédé est quasiment ininterrompu , sans perte de temps. Avantageusement, la direction donnée au premier poste est perpendiculaire à la direction prédéterminée au second poste.Thus the progress of all the stages of the process is almost uninterrupted, without loss of time. Advantageously, the direction given to the first station is perpendicular to the predetermined direction at the second station.

Ce procédé peut être mis en oeuvre dans une installation de transfert et de positionnement qui, conformément à l'invention, est caractérisée en ce qu'elle comprend :

  • - une table plane sur laquelle glisse la pièce, qui est mobile en hauteur et sur laquelle figurent virtuellement deux emplacements donnés,
  • - un moyen de transfert et de positionnement, capable de prendre en charge la pièce dès que celle-ci atteint le premier emplacement donné, de transférer la pièce du premier au second emplacement donné, tout en modifiant sa position de sorte qu'elle ait la position prédéterminée, lorsqu'elle atteint ledit second emplacement,
  • . un second moyen de transfert pour transférer la pièce au second poste dans la direction et la position prédéterminées, capable de prendre en charge la pièce dès que celle-ci atteint le second emplacement donné,
  • . des moyens pour abaisser la table mobile lorsque la pièce atteint le premier emplacement donné,
  • . des moyens pour relever la table mobile lorsque la pièce atteint le second emplacement donné.
This method can be implemented in a transfer and positioning installation which, according to the invention, is characterized in that it comprises:
  • - a flat table on which the piece slides, which is movable in height and on which there are virtually two given locations,
  • a means of transfer and positioning, capable of taking over the part as soon as it reaches the first given location, of transferring the piece from the first to the second given location, while modifying its position so that it has the predeter position mined, when it reaches said second location,
  • . a second transfer means for transferring the part to the second station in the predetermined direction and position, capable of taking over the part as soon as it reaches the second given location,
  • . means for lowering the movable table when the workpiece reaches the first given location,
  • . means for raising the movable table when the piece reaches the second given location.

La pièce est alimentée du premier poste par glissement sur une surface plane grâce au déplacement du premier moyen de transfert qui peut être une courroie; lorsque la pièce atteint le premier emplacement donné, la table mobile dont la surface de clissement est en position haute dans le prolongement de la surface de glissement du premier poste, s'abaisse, dégageant ainsi la pièce du contact avec le premier moyen de transfert. Simultanément à l'abaissement de la table mobile, la pièce est prise en charge par le moyen de transfert et de positionnement qui la transfère par glissement sur la table mobile, du premier au second emplacement donné tout en lui conférant la position déterminée lorsqu'elle atteint ledit second emplacement. Simultanément, lorsque la pièce atteint ce second emplacement donné, la table mobile se relève et la pièce, libérée du moyen de transfert-positionnement, est prise en charge par le second moyen de transfert qui transfère la pièce, par glissement sur une surface qui est dans le prolongement de la surface de glissement de la table mobile en position haute, au second poste dans la direction et la position prédéterminées.The part is fed from the first station by sliding on a flat surface thanks to the displacement of the first transfer means which can be a belt; when the workpiece reaches the first given location, the movable table, the sliding surface of which is in the high position in line with the sliding surface of the first station, lowers, thereby releasing the workpiece from contact with the first transfer means. Simultaneously with the lowering of the movable table, the workpiece is supported by the transfer and positioning means which transfers it by sliding on the movable table, from the first to the second given location while giving it the determined position when it reaches said second location. Simultaneously, when the part reaches this second given location, the movable table is raised and the part, freed from the transfer-positioning means, is taken up by the second transfer means which transfers the part, by sliding on a surface which is in the extension of the sliding surface of the movable table in the high position, at the second station in the predetermined direction and position.

Les moyens pour abaisser la table mobile lorsque la pièce atteint le premier emplacement donné comprennent un élément capteur de position qui matérialise le premier emplacement donné et un élément d'appui qui exerce sur la table une pression suffisante pour que celle-ci passe de la positon haute à la position basse. La position haute correspond à celle où la pièce est à la fois en contact avec le premier moyen de transfert du premier poste et avec la surface de la table ; la position basse correspond à celle où la pièce est uniquement en contact avec la surface de la table, et n'est donc plus entraînée par le premier moyen de transfert. L'élément capteur de position commande le déplacement vertical de l'élément d'appui de telle sorte que, compte-tenu de l'inertie mécanique, la pièce atteigne le premier emplacement donné lorsque l'élément d'appui a fait passer la table de la position haute à la position basse.The means for lowering the movable table when the workpiece reaches the first given location comprises a position sensor element which materializes the first given location and a support element which exerts on the table sufficient pressure for it to pass from the position high to low position. The high position corresponds to that where the part is both in contact with the first means of transfer of the first station and with the table surface; the low position corresponds to that where the workpiece is only in contact with the surface of the table, and is therefore no longer driven by the first transfer means. The position sensor element controls the vertical movement of the support element so that, taking into account the mechanical inertia, the part reaches the first given location when the support element has passed the table from the high position to the low position.

Le moyen de transfert et de positionnement comporte un organe de déplacement, qui en se déplaçant peut tourner sur lui-même autour d'un axe perpendiculaire au plan du déplacement. Avantageusement l'organe de déplacement est lui-même l'élément d'appui qui déplace la table en hauteur. Ainsi lorsque l'élément capteur de position détecte la présence de la pièce, l'élément d'appui et de déplacement vient s'appliquer sur la pièce dès que celle-ci a atteint le premier emplacement donné, la pression exercée sur la pièce met la table en position basse,ce qui dégage la pièce du premier moyen de transfert, et simultanément l'élément d'appui et de déplacement déplace la pièce sur la table vers le second emplacement donné. Pendant le déplacement de l'élément d'appui et de déplacement du premier au second emplacement donnés, il tourne sur lui-même autour d'un axe perpendiculaire au plan de déplacement, de sorte que la pièce ait la position prédéterminée lorsqu'elle atteint le second emplacement donné.The transfer and positioning means comprises a displacement member, which by moving can rotate on itself around an axis perpendicular to the plane of displacement. Advantageously, the displacement member is itself the support element which displaces the table in height. So when the position sensor element detects the presence of the part, the support and displacement element is applied to the part as soon as it has reached the first given location, the pressure exerted on the part puts the table in the low position, which releases the workpiece from the first transfer means, and simultaneously the support and displacement element moves the workpiece on the table to the second given location. During the displacement of the support and displacement element from the first to the second given location, it turns on itself around an axis perpendicular to the plane of displacement, so that the part has the predetermined position when it reaches the second location given.

Les moyens pour relever la table mobile lorsque la pièce atteint le second emplacement donné comprennent un second élément capteur de position qui correspond au second emplacement donné et un élément de contre-appui qui fait revenir la table mobile de la position basse, où la maintenait l'élément d'appui, à la position haute. Avantageusement le second élément canteur de position commande le relèvement de l'élément d'appui, de telle sorte que, compte-tenu de l'inertie mécanique, la pièce atteigne le second emplacement donné lorsque, l'élément d'appui n'exerçant plus sa pression sur la table, celle-ci passe en position haute. A cet instant la pièce est alors prise en charge par le second moyen de transfert , qui peut être une ou plusieurs courroies ayant la direction prédéterminée ; dans ce cas la courroie entraine la pièce par glissement vers le second poste dansThe means for raising the movable table when the workpiece reaches the second given location comprises a second position sensor element which corresponds to the second given location and a counter-support element which brings the movable table back from the low position, where it holds it. support element, in the high position. Advantageously, the second position-setting element controls the raising of the support element, so that, taking into account the mechanical inertia, the part reaches the second given location when, the support element not exerting the more his pressure on the table, it goes to the high position. At this instant the part is then taken over by the second transfer means, which can be one or more belts having the predetermined direction; in this case the belt drives the part by sliding towards the second station in

Il est généralement préférable pour faciliter les réglages que les courroies assurant les transferts au premier et au second poste aient des directions perpendiculaires.the predetermined position and direction. It is generally preferable to facilitate the adjustments that the belts ensuring the transfers to the first and to the second station have perpendicular directions.

  • - - la figure 1 est une vue en perspective d'une installation de transfert et de positionnement.
  • - les figures 2A, 2B, 2C et 2D sont des représentations schématiques des différentes étapes du fonctionnement de l'installation.
  • - la figure 3 représente un exemple d'application'du procédé à la fermeture des manches.
An embodiment of the installation for implementing the method according to the present invention and an example of application are described below by way of nonlimiting examples with reference to the appended drawings in which:
  • - - Figure 1 is a perspective view of a transfer and positioning installation.
  • - Figures 2A, 2B, 2C and 2D are schematic representations of the different stages of operation of the installation.
  • - Figure 3 shows an example of a p plication'du for sealing sleeves.

L'installation de transfert et de positionnement comporte une table 1 mobile en hauteur, soit, comme cela est représenté aux figures 1 et 2, que ladite table peut pivoter autour d'un axe 2 parallèle à la direction d'alimentation de la pièce, soit que la table 1 peut se déplacer tout entière verticalement. La surface de la table 1, lorsque celle-ci est en position haute, est dans le même plan avec d'une part la surface de glissement correspondant au premier poste d'où provient la pièce et d'autre part à celle correspondant au second poste vers lequel elle est dirigée. Par ailleurs ces trois surfaces sont approximativement jointives, de sorte qu'une pièce peut passer par glissement de l'une à l'autre sans qu'il y ait formation de plis ou autres défauts. La courroie 3, qui véhicule la pièce du premier poste,s'étend à la fois sur la surface de glissement dudit premier poste et sur une partie de la table 1. A proximité immédiate de l'emplacement de la courroie 3, une fenêtre 4 pratiquée dans la table 1 et une lampe non représentée sont placées en regard d'une cellule photo-électrique 5. Monté sur un chariot 6, déplaçable d'avant en arrière grâce à un système 7 de bielle-manivelle, l'élément d'appui et de déplacement consiste en un peigne 8 qui comporte deux doigts 9 et 10, dont l'-un 9 est monté fixe sur le chariot 6 tandis que l'autre 10 peut pivoter autour de l'axe vertical constitue par le doigt 9. Le peigne 8 se déplace de haut en bas grâce à l'ouverture de la gâchette 11, ouverture commandée par la cellule photoélectrique 5 quand elle détecte la présence de la pièce sur la table 1 au droit de la fenêtre 4. Le peigne 8 se déplace latéralement grâce au déplacement du chariot 6 lui-même. Pendant le déplacement latéral du peigne 8, le doigt 10 pivote d'un certain angle autour du doigt 9 : ce pivotement est obtenu par l'action conjuguée du ressort de compression 12 qui tend à repousser le doigt 9, et du galet 13 qui limite ce pivotement, le galet 13 étant solidaire du peigne 8 et prenant appui sur une rampe 14.L'angle de cette rampe 14 par rapport à la direction prédéterminée 6 est réglable au moyen de la vis 15, la rampe 14 étant rappelée contre cette vis par un ressort non représenté. En fin de course du chariot 6 une butée 16 déclenche le relèvement du peigne 8 en prenant appui sur le levier 17, solidaire du peigne 8. Le cycle complet de déplacement du peigne 8 comprend donc 4 phases continues : descente, déplacement latéral par exemple de gauche à droite sur la figure 1, remontée, déplacement de droite à gauche. Le bon fonctionnement de ce cycle est assuré par un ensemble guide, dont une partie constituée par une roulette 18 est solidaire du levier 17 et donc du chariot 6 et dont l'autre partie, constituée par deux barres 19 et 20, est fixe par rapport au chariot 6. La barre 19 parallèle à la barre 20 est montée au-dessus de celle-ci. L'une de ses extrémités est située en regard de la gâchette 11, tandis que l'autre extrémité surplombe l'extrémité cor- respondante de la barre 20. Les courroies 21 et 22, qui ont la direction prédéterminée,r)erpendiculaire à celle de la courroie 3, et qui assurent le transfert de la pièce vers le second poste, s'étendent à la fois sur la surface de glissement dudit second poste et sur une partie de la table 1.The transfer and positioning installation comprises a table 1 movable in height, that is, as shown in FIGS. 1 and 2, that said table can pivot around an axis 2 parallel to the direction of supply of the part, or that table 1 can move entirely vertically. The surface of table 1, when the latter is in the high position, is in the same plane with on the one hand the sliding surface corresponding to the first station from which the part originates and on the other hand to that corresponding to the second post to which it is directed. Furthermore, these three surfaces are approximately contiguous, so that a part can pass by sliding from one to the other without the formation of folds or other defects. The belt 3, which conveys the part of the first station, extends both over the sliding surface of said first station and on a part of the table 1. In the immediate vicinity of the location of the belt 3, a window 4 made in the table 1 and a lamp not shown are placed opposite a photoelectric cell 5. Mounted on a carriage 6, movable back and forth by means of a rod-crank system 7, the support and displacement element consists of a comb 8 which has two fingers 9 and 10, one of which 9 is mounted fixed on the carriage 6 while the other 10 can pivot around the vertical axis constitutes by the finger 9. The comb 8 moves up and down thanks to the opening of the trigger 11, opening controlled by the photoelectric cell 5 when it detects the presence of the part on the table 1 to the right of the window 4. The comb 8 moves laterally thanks to the movement of the carriage 6 itself. During the lateral displacement of the comb 8, the finger 10 pivots by a certain angle around the finger 9: this pivoting is obtained by the combined action of the compression spring 12 which tends to repel the finger 9, and of the roller 13 which limits this pivoting, the roller 13 being integral with the comb 8 and bearing on a ramp 14.The angle of this ramp 14 relative to the predetermined direction 6 is adjustable by means of the screw 15, the ramp 14 being biased against this screw by a spring not shown. At the end of the carriage 6 travel, a stop 16 triggers the raising of the comb 8 by pressing on the lever 17, integral with the comb 8. The complete movement cycle of the comb 8 therefore comprises 4 continuous phases: descent, lateral movement for example of left to right in Figure 1, ascent, moving from right to left. The proper functioning of this cycle is ensured by a guide assembly, a part of which consists of a wheel 18 is integral with the lever 17 and therefore of the carriage 6 and the other part of which, consisting of two bars 19 and 20, is fixed relative to to the carriage 6. The bar 19 parallel to the bar 20 is mounted above the latter. One of its ends is located opposite the trigger 11, while the other end overhangs the end corresponding sponding res of the bar 20. The belts 21 and 22, which have the predetermined direction, r) erpendiculaire to that of the belt 3, and that transfer of the piece towards the second station, extend both over the sliding surface of said second station and over part of the table 1.

Le fonctionnement de l'installation de transfert et de positionnement est le suivant. La pièce 23 est véhiculée grâce à la courroie 3 par glissement sur la surface horizontale de glissement du premier poste puis partiellement sur la table 1 (figure 2A). Lorsqu'elle passe au droit de la fenêtre 4, l'interruption de l'éclairement de la lampe située en dessous de cette fenêtre est détectée par la cellule photo-électrique 5, qui commande l'ouverture de la gâchette 11. La roulette 18 qui était maintenue entre la gâchette 11 et la barre 19 est libérée, et autorise la descente du peigne 8 jusqu'à ce que la roulette 18 rencontre la barre 20. Le peigne 8 en s'abaissant s'appuie sur la pièce 23 à l'aide des doigts 9 et 10, et exerce une pression sur la table 1 qui pivote autour de l'axe 2(fig2B). Lors du déplacement de gauche à droite du chariot 6 sous l'effet de la bielle-manivelle 7, le peigne 8 entraine la pièce 23 qui glisse sur la surface inclinée de la table 1 (fiqure 2C). L'inclinaison de la table 1 est identique à celle des barres 19 et 20 par rapport à l'horizontale, puisque c'est le déplacement de la roulette 18 le long de la tige 20 qui guide le déplacement du peigne 8. Pendant le même déplacement du chariot 6, le galet 13 solidaire du peigne 8 suit la direction de la rampe 14 contre laquelle il est appuyé sous l'effet du ressort de compression 12 : ainsi pendant ce déplacement latéral, le doigt 10, qui suit le 'mouvement du galet 13, pivote autour de l'axe vertical formé par le doigt 9. Ce mouvement relatif des deux doigts 9 et 10 l'un par rapport à l'autre permet de donner à la pièce 23 la position désirée. En fonction des pièces à traiter sur l'installation, l'angle selon lequel la pièce va pivoter autour du doigt fixe 9, pendant le déplacement latéral de gauche à droite , peut être réglé en modifiant l'angle formé par la rampe 14 par rapport à la direction du transfert du chariot, par action sur la vis de réglage 15. En fin de ce déplacement latéral, la butée 16 prend appui sur le levier 17 solidaire du chariot 6. En basculant, le levier 17 relève à la fois la roulette 18 et le peigne 8. Une fois relevé, le peigne 8 n'exerce plus de pression sur la table 1, et celle-ci retrouve la position haute sous l'effet du contrepoids 24 : la pièce 23 vient en contact avec les courroies 21 et 22 qui ont la direction déterminée, et est entraînée par elles dans la position et la direction déterminées par glissement d'abord sur une partie de la table 1 puis sur la surface de glissement du second poste (figure 2D). Pendant ce temps, la bielle-manivelle poursuit l'entraînement du chariot 6 : la roulette 18, relevée sous l'action du levier 17, est passée sur la tige 19 et guide dans son déplacement de droite à gauche le peigne 8 vers la position initiale. Une nouvelle pièce 23 est alimentée du premier poste , et le cycle reprend.The operation of the transfer and positioning installation is as follows. The part 23 is conveyed by means of the belt 3 by sliding on the horizontal sliding surface of the first station and then partially on the table 1 (FIG. 2A). When it passes to the right of window 4, the interruption of the illumination of the lamp located below this window is detected by the photoelectric cell 5, which controls the opening of the trigger 11. The wheel 1 8 which was held between the trigger 11 and the bar 19 is released, and authorizes the descent of the comb 8 until the caster 18 meets the bar 20. The comb 8 while lowering rests on the part 23 to using fingers 9 and 10, and exerts pressure on the table 1 which pivots around the axis 2 (fig2B). When moving from left to right of the carriage 6 under the effect of the connecting rod-crank 7, the comb 8 drives the part 23 which slides on the inclined surface of the table 1 (figure 2C). The inclination of the table 1 is identical to that of the bars 19 and 20 relative to the horizontal, since it is the movement of the caster 18 along the rod 20 which guides the movement of the comb 8. During the same displacement of the carriage 6, the roller 13 secured to the comb 8 follows the direction of the ramp 14 against which it is pressed under the effect of the compression spring 12: thus during this lateral displacement, the finger 10, which follows the ' movement of the roller 13, pivots about the vertical axis formed by the finger 9. This relative movement of the two fingers 9 and 10 relative to each other makes it possible to give the part 23 the desired position. Depending on the parts to be treated on the installation, the angle by which the part will pivot around the fixed finger 9, during lateral movement from left to right, can be adjusted by modifying the angle formed by the ramp 14 relative to the direction of transfer of the carriage, by action on the adjusting screw 15. At the end of this lateral movement, the stop 16 bears on the lever 17 secured to the carriage 6. By tilting, the lever 17 raises both the wheel 18 and the comb 8. Once raised, the comb 8 no longer exerts pressure on the table 1, and it returns to the high position under the effect of the counterweight 24: the part 23 comes into contact with the belts 21 and 22 which have the direction determined, and is driven by them in the position and direction determined by sliding first on a part of the table 1 then on the sliding surface of the second station (Figure 2D). During this time, the connecting rod-crank continues to drive the carriage 6: the caster 18, raised under the action of the lever 17, is passed over the rod 19 and guides in its movement from right to left the comb 8 towards the position initial. A new part 23 is supplied from the first station, and the cycle resumes.

La mise en oeuvre du procédé et de l'installation selon l'invention est particulièrement adaptée à la fermeture des manches courtes telles que des manches de tee-shirt, comme le montre la figure 3. Dans ce cas la pièce 23 est une manche provenant d'un premier poste de finition ayant effectué par exemple l'ourlage ou le colletage du bas de la manche (25), puis le pliage (26) de la manche selon un axe de symétrie 27 et de façon à ce qu'il y ait recouvrement exact des deux parties de la manche l'une sur l'autre . Une fois pliée, la pièce 23 doit être fermée cette fermeture s'ef- fectuepar couture des deux bords 28,, ajustés et superposés. Compte-tenu de la conformation de la manche 23, il est alors nécessaire d'amener la ligne de couture 28 sous la machine à coudre 29 dans une direction et une position différentes de celles qu'elle avait en sortant du pliage 26. Comme montré sur la figure 3, il faut à la fois transférer la manche 23 du poste de pliage 26 au poste de couture 30 et lui faire subir une rotation partielle sur elle-même , de manière à placer exactement la ligne de couture 28 en position et en direction sous la machine à coudre.The implementation of the method and the installation according to the invention is particularly suitable for closing short sleeves such as t-shirt sleeves, as shown in Figure 3. In this case the part 23 is a sleeve from of a first finishing station having effected for example the hemming or the colleting of the bottom of the sleeve (25), then the folding (26) of the sleeve along an axis of symmetry 27 and so that there has exact overlap of the two parts of the sleeve one over the other. Once folded, the part 23 must be closed. This closure is effected by sewing the two edges 28, adjusted and superimposed. Given the shape of the sleeve 23, it is then necessary to bring the seam line 28 under the sewing machine 29 in a direction and a position different from that which it had when leaving the fold 26. As shown in FIG. 3, it is necessary both to transfer the sleeve 23 from the folding station 26 to the sewing station 30 and to make it undergo a partial rotation on itself, so as to exactly place the seam line 28 in position and in direction under the sewing machine.

Bien entendu l'installation selon l'invention comporte tous les réglages nécessaires aux changements de pièces et de position, notamment réglage de la rampe (14) par la vis (15) mais également réglage du ou des doigts (9 et 10) en fonction de lataille des pièces , réglage de délai de commande du capteur opto-électronique en fonction du choix du premier emplacement, réglage de la butée (16) et de la course de la bielle-manivelle (7) en fonction de la longueur du déplacement latéral souhaitée.Of course, the installation according to the invention comprises all the adjustments necessary for changes of parts and position, in particular adjustment of the ramp (14) by the screw (15) but also adjustment of the finger (s) (9 and 10) depending of the size of the parts, adjustment of the opto-electronic sensor control delay as a function of the choice of the first location, adjustment of the stop (16) and of the stroke of the crank-rod (7) as a function of the length of the lateral displacement desired.
