Abstract

A pair of horizontal finned tubes (10) slides into the legs (3) of a pair of tights up to a predetermined posn. marked on each tube and detected by a photo-electric detector (56). The jaws (52,52') of a pneumatically-operated clamp then, independently, pinch the legs onto the fins of each tube and hold them in posn. for precise cutting of their extremities (31). After cutting, the jaws open to release the tights. Six units of the appts. are arranged on a rotating carousel; each is mounted on a chariot (5) and, in turn, slides forwards on a runner (6) to seize a pair of tights. The movement of the chariot (5) is controlled by a movable switch mounted adjacent to the runner (6). The various operations of the appts., and the cutting, are performed at different stages of the carousel's rotation.

Description

L'invention concerne un procédé et un dispositif pour placer automatiquement, dans une quelconque po sition prédéfinie, les deux bas tubulaires d'un col lant sur les tubes d'un appareil de retounement pneumatique d'une machine à coudre les pointes de collant afin de permettre la couture correcte et précise de ces pointes.The invention relates to a method and a device for automatically placing, in any predefined position, the two tubular stockings of a collar on the tubes of a pneumatic retuning device of a machine for sewing sticky points in order to to allow the correct and precise sewing of these points.

On sait que dans les machines à coudre les pointes de bas tubulaires le tube de l'appareil de retournement pneumatique sert à soutenir le bas retourné et deux ailettes latérales, coulissant longitudinalement par rapport audit tube, servent faire glisser vers la machine à coudre la pointe du bas à cou dre.We know that in sewing machines the tips of tubular stockings the tube of the pneumatic turning device is used to support the turned bottom and two lateral fins, sliding longitudinally with respect to said tube, are used to slide towards the sewing machine from the bottom to the neck.

On connaît en outre, suite au brevet GB 1.577.758, un dispositif automatique pour placer l'extrémité du bas à coudre dans une position prédéfinie du tube de l'appareil de retournement pneumatique, lequel comprend un capteur de position (par ex. une photocellule) fixe, apte à reconnaître un détail (par ex. l'extrémité ouverte) du bas, et des engins pour saisir le bas en correspondance avec les ailet tes latérales du retourneur, pour le faire avancer le long du tube, d'abord en avant, c'est - à - dire dans le sens de son extrémité ouverte et de façon que ledit détail du bas dépasse le capteur, puis en arrière et ce jusqu'à ce que ledit détail du bas ar rive dans une position correspondant à celle du capteur, lequel commande alors l'ouverture des engins de prise.Furthermore, following GB 1,577,758, an automatic device is known for placing the end of the stocking to be sewn in a predefined position of the tube of the pneumatic turning device, which comprises a position sensor (for example a photocell) fixed, able to recognize a detail (eg the open end) of the bottom, and devices to grip the bottom in correspondence with the lateral fins of the turner, to move it along the tube, first forward, that is to say in the direction of its open end and so that said bottom detail exceeds the sensor, then back and this until said bottom detail arrives in a position corresponding to that of the sensor, which then controls the opening of the gripping machines.

Ce dispositif connu utilise des engins de prise qui se referment sur le bas toujours dans la même position par rapport au tube et qui font avancer le bas toujours selon une course de même longueur; et étant donné que l'estrémité ouverte du bas, à la fin du retournement de celui-ci sur le tube, résulte mise dans une position qui varie suivant une mar ge fort large, lesdits engins de prise se referment toujours sur le bas à une certaine distance de la fin de celui-ci. En conséquence, durant l'avancement du bas vers l'extrémité libre du tube, même s'il a lieu à faible vitesse, se forment de nombreux plis dans la zone de terminaison du bas, qui se trouve hors des engins de prise; pour éliminer ces plis, il faut alors tirer le bas en arrière à faible vitesse.This known device uses gripping machines which close on the bottom always in the same position relative to the tube and which advance the bottom always in a stroke of the same length; and given that the open end of the bottom, at the end of the turning of the latter on the tube, results in a position which varies according to a very wide margin, said gripping devices always close on the bottom at a certain distance from the end of it. Consequently, during advancement from the bottom towards the free end of the tube, even if it takes place at low speed, numerous folds form in the bottom termination zone, which is outside of the gripping devices; To eliminate these folds, you must then pull the bottom back at low speed.

L'objectif principal de la présente invention est d'éliminer les inconvénients susmentionnés. L'inven tion, telle qu'elle est caractérisée par les revendications, résoud le problème de faire glisser les deux bas d'un collant sur les deux tubes à ailettes d'un appareil de retournement pneumatique, à partir d'une quelconque position initiale de chaque bas vers une même position finale prédéfinie pour les deux bas, avec une seule et rapide course d'approche.The main objective of the present invention is to eliminate the above-mentioned drawbacks. The invention, as characterized by the claims, solves the problem of sliding the two socks of tights over the two finned tubes of a pneumatic turning device, from any initial position from each stocking to the same predefined end position for both stockings, with a single rapid approach run.

Conformément à l'invention, il est prévu d'utiliser un chariot mobile de direction parallèle à l'axe des tubes de l'appareil de retournement et portant deux sondes détectrices de la position des deux bas et deux couples de pinces pour entraîner la pointe des bas à coudre le long des ailettes latérales des tubes de l'appareil de retounement; tandis que, durant la course du chariot vers l'extrémité libre des tubes, chaque sonde individualise un point prédéterminé décelable du bas correspondant, elle commande à la paire correspondante de pinces de se refermer sur le bas de façon à permettre de l'entrai- ner vers et jusq'à la fin de la course du chariot à laquelle correspond l'ouverture automatique de toutes les pinces et partant la position finale et prédéfinie des bas sur les tubes de l'appareil de retournement.In accordance with the invention, it is planned to use a mobile steering carriage parallel to the axis of the tubes of the turning device and carrying two probes detecting the position of the two bottoms and two pairs of pliers to drive the point sewing stockings along the lateral fins of the tubes of the retuning apparatus; while, during the travel of the carriage towards the free end of the tubes, each probe individualizes a predetermined point detectable from the corresponding bottom, it commands the corresponding pair of pliers to close on the bottom so as to allow the entrainment ner towards and until the end of the carriage stroke to which corresponds the automatic opening of all the grippers and therefore the final and predefined position of the stockings on the tubes of the turning device.

Les avantages obtenus grâce à la présente invention consistent essentiellement en ce qu'il est possible d'opérer le retournement préalable des bas sur les tubes de l'appareil de retournement à une vitesse plus élevée de celle obtenue jusqu'à présent; que les bas glissent littéralement jusqu'à la position prédéfinie et ce en une seule course d'approche; que chaque bas est toujours saisi à la hauteur de son extrémité ouverte, quelle que soit la position de départ de chaque bas; que le glissement des deux bas est réalisé à une vitesse fort élevée et avec le tissu en position tendue; qu'il est possible de modifier la position de relâchement du bas.The advantages obtained thanks to the present invention essentially consist in the fact that it is possible to operate the prior turning of the stockings on the tubes of the turning device at a higher speed than that obtained up to now; that the stockings literally slide to the predefined position in a single approach run; that each stocking is always grasped at the height of its open end, whatever the starting position of each stocking; that the sliding of the two stockings is carried out at a very high speed and with the fabric in the stretched position; that it is possible to modify the release position of the bottom.

L'invention est esposée plus en détail dans les pages qui suivent, à l'aide des dessins qui en représentent un exemple d'exécution.The invention is set out in more detail in the pa ges which follow, using the drawings which represent an example of execution.

  • - A carriage 5, movable in phase relative to the movements of the carousel 1, on a horizontal rail 6, arranged below the two tubes 10, stopped at the station C; said carriage 5 carries in its upper part three stirrups 50, of vertical profile in the shape of C, justaposited, oriented in parallel with said tubes 10 and interconnected by crosspieces 51, so as to allow free passage for the tubes 10 during the rotation, step by step, of carousel 1.

A chaque couple. d'étriers 50 contigus sont associées deux mâchoires 52 et 52' horizontales, articu lées sur le bras, respectivement supérieur et inférieur, des étriers correspondants 50 et reliées entre elles au moyen d'un système de leviers 53 pour former deux pinces correspondantes (52,52') lesquelles se referment longitudinalement et de part et d'autre sur les ailettes latérales 11 de chaque tube 10, sous l'effet de deux ressorts de rappel 54 et, au contraire, s'ouvrent par action d'un cylindre pneumatique 55. A la traverse supérieure 51 sont associées deux sondes 56 photo-electroniques, alignées entre elles en direction transversale, au-dessus des tubes 10, chacune des sondes étant située- en retrait par rapport aux deux extrémités des mâchoires 52 du tube correspondant 10: la position de chacune des sondes 56 en direction parallèle à l'axe du tube 10 correspondant pouvant être réglée à volonté en rapport avec le point-indice 30 prédéfini du bas 3 et avec la position prédéterminée du bas sur le tube 10. Chacune desdites sondes 56 est reliée à un cylindre correspondant 55 de manière à effectuer, séparément,la fermeture des pinces correspondantes (52,52') sur les ailettes 11 des deux tubes 10 lorsque, après que chaque bas 3 a été exploré séparément sous l'effet du mouvement du chariot 5, le point-indice prédéterminé 30 de chaque bas 3 a été décelé.To each couple. adjoining stirrups 50 are associated with two horizontal jaws 52 and 52 ′, articulated on the upper and lower arms, respectively, of the corresponding stirrups 50 and connected together by means of a system of levers 53 to form two corresponding clamps (52 , 52 ') which close longitudinally and on either side on the lateral fins 11 of each tube 10, under the effect of two return springs 54 and, on the contrary, open by the action of a pneumatic cylinder 55. The upper cross-member 51 is associated with two photoelectronic probes 56, aligned with one another in transverse direction, above the tubes 10, each of the probes being set back from the two ends of the jaws 52 of the corresponding tube 10 : the position of each of the probes 56 in the direction parallel to the axis of the corresponding tube 10 can be adjusted at will in relation to the predefined index point 30 at the bottom 3 and with the predetermined position at the bottom on the tu be 10. Each of said probes 56 is connected to a corresponding cylinder 55 so as to carry out, separately, the closing of the corresponding clamps (52,52 ') on the fins 11 of the two tubes 10 when, after each bottom 3 has been explored separately under the effect of the movement of the carriage 5, the predetermined index point 30 of each stocking 3 has been detected.

Enfin, chacun desdits cylindres 55 est asservi à un seul interrupteur 57 de fin de course du chariot 5 de façon à désamorcer toutes les pinces (52,52') et ainsi de provoquer l'immôbilisation des deux bas 3 dans la position prédéfinie sur les deux tubes 10.Finally, each of said cylinders 55 is controlled by a single switch 57 of the end of travel of the carriage 5 so as to defuse all the clamps (52,52 ') and thus cause the immobilization of the two bottoms 3 in the predefined position on the two tubes 10.

Conformément à l'invention, il est également prévu d'utiliser deux sondes 56 pour chaque tube 10 de 1' appareil de retournement pneumantique, disposées au-dessus du tube, à proximité des ailettes latérales, l'une associée à une pince (52,52') et l'autre associée à l'autre pince et deux cylindres correspondants 55 permettant d'actionner les pinces (52,52') séparément, de façon à permettre de saisir le bas sur les deux ailettes 11 du tube 10 à des mo ments différents et de façon à obtenir que l'extrémité ouverte du bas qui, à la fin du retournement se trouverait orientée en oblique par rapport à l' axe-même du tube, soit disposée, à la fin du glissement, de manière perpendiculaire par rapport à l' axe du tube 10.In accordance with the invention, it is also planned to use two probes 56 for each tube 10 of the pneumatic turning device, arranged above the tube, near the lateral fins, one associated with a clamp (52 , 52 ') and the other associated with the other clamp and two corresponding cylinders 55 enabling the clamps (52,52') to be actuated separately, so as to allow the bottom to be grasped on the two fins 11 of the tube 10 to at different times and in such a way that the open end of the bottom which, at the end of the inversion would be oriented obliquely to the very axis of the tube, is arranged, at the end of the sliding, so perpendicular to the axis of the tube 10.

Le fonctionnement a lieu comme suit. Tandis que le carrousel 1 avance d'un pas, la chariot 5 effectue une course d'aller à vide, c'est-à-dire avec les pinces (52,52') ouvertes, vers le centre du carrousel 1 et lorsque les deux tubes 10 avec les deux bas 3 retournés sur ceux-ci atteignent la station C et s'y arrêtent, le chariot 5 est déjà arrivé à la fin de sa course d'aller et s'est arrêté. Le chariot 5 effectue immédiatement sa course de retour, durant laquelle, chacune des deux sondes 56 commence par explorer longitudinalement le bas correspondant 3 et aussitôt qu'elle à décelé le point-indice prédéfini 30, elle ordonne le désamorçage du cylindre correspondant 55, en provoquant ainsi la fermeture des pinces correspondantes (52,52'); ensuite, l'extrémité 31 de chaque bas 3 est entraînée jusqu' à la fin de la course de retour du chariot 5; une fois celle-ci atteinte, au moyen de l'interrupteur 57, ledit chariot 5_ commande la mise en action des deux cylindres 55, en provoquant ainsi l'ouverture instantanée de toutes les pinces (52, 52') et partant l'immobilisation des pointes des deux bas 3, dans la position prédéfinie sur les tubes 10. Le carrousel 1 avance alors d'un pas et porte les tubes 10 à la station D1: là les ailettes latérales 11 d'un des tubes 10, en avançant le long du tube au-delà de son extrémité, transportent l'extrémité du bas correspondant à coudre dans la zone où se trouve la machine coupe-couture 4 qui se trouve à la station D1; de même, à la station suivante D2, les ailettes 11 de l'autre tube 10 transporteront l'extrémité de l'autre bas 3 à coudre en face de la machine coupe-couture 4 qui se trouve à ladite station D2 de la machine à coudre les pointes.Operation takes place as follows. As the carousel 1 advances by one step, the carriage 5 carries out an empty travel, that is to say with the clamps (52,52 ') open, towards the center of the carousel 1 and when the two tubes 10 with the two bottoms 3 turned over on them reach station C and stop there, the carriage 5 has already arrived at the end of its outward travel and has stopped. The carriage 5 immediately performs its return stroke, during which each of the two probes 56 begins by longitudinally exploring the corresponding bottom 3 and as soon as it detects the predefined index point 30, it orders the defusing of the corresponding cylinder 55, thereby causing the corresponding clamps to be closed (52, 52 '); then, the end 31 of each bottom 3 is driven until the end of the return stroke of the carriage 5; once this has been achieved, by means of the switch 57, said carriage 5_ controls the actuation of the two cylinders 55, thereby causing instantaneous opening of all the clamps (52, 52 ') and hence immobilization tips of the two bottoms 3, in the predefined position on the tubes 10. The carousel 1 then advances by one step and carries the tubes 10 to the station D1: there the lateral fins 11 of one of the tubes 10, advancing the along the tube beyond its end, transport the end of the bottom corresponding to sewing in the area where the sewing machine 4 is located which is at the station D1; similarly, at the next station D2, the fins 11 of the other tube 10 will transport the end of the other stocking 3 to be sewn in front of the sewing machine 4 which is at said station D2 of the machine sew the tips.
