Description
La présente invention a pour objet un procédé pour le transfert d'un collant d'une machine à coudre les collants à une machine à coudre les pointes et un dispositif pour sa mise en oeuvre.The subject of the present invention is a method for transferring a pantyhose from a pantyhose sewing machine to a spike sewing machine and a device for its implementation.
Il est connu des techniciens du secteur que, à la sortie d'une machine qui effectue la couture d'union de deux bas pour former un collant, les jambes du vêtement tendent à s'enchevêtrer l'une avec l'autre en tortillon et que leur séparation s'avère nécessaire pour permettre le transfert du collant pour le soumettre à d'autres opérations, comme par exemple à une machine qui effectue la couture de la pointe des pieds.It is known to the technicians of the sector that, at the exit of a machine which performs the seam of union of two stockings to form a pantyhose, the legs of the garment tend to become entangled with each other in twist and that their separation proves to be necessary to allow the transfer of the tights to subject it to other operations, such as for example to a machine which performs the sewing of the tiptoes.
Il est également connu que, actuellement, pour empêcher cet entortillement des jambes, les deux bas sont posés à la main sur des supports correspondants de la machine à coudre les collants et ceci avant qu'ils ne soient cousus.
Mais le temps nécessaire pour cette opération manuelle est, pour des opérateurs non spécialisés, trop long par rapport au temps de couture d'union des bas qui est de quelques secondes; de sorte que cette opération nécessite l'emploi de personnel particulièrement entraîné, pour effectuer aussi rapidement et pendant de longues périodes de temps le positionnement des bas sur les supports précités, mais, malgré tout, il n'est pas possible d'exploiter au maximum la capacité de production de la machine à coudre les pointes, laquelle est ainsi limitée par la vitesse de cette opération manuelle. Cette limitation et le coût élevé de la main-d'oeuvre spécialisée contribuent à l'augmentation du coût de fabrication du collant.It is also known that, currently, to prevent this kinking of the legs, the two stockings are placed by hand on corresponding supports of the pantyhose sewing machine and this before they are sewn.
But the time necessary for this manual operation is, for non-specialized operators, too long compared to the seam time for joining the stockings which is a few seconds; so that this operation requires the use of specially trained personnel, to perform as quickly and for long periods of time the positioning of the stockings on the aforementioned supports, but, despite everything, it is not possible to make the most of the production capacity of the stitch sewing machine, which is thus limited by the speed of this manual operation. This limitation and the high cost of specialized labor contribute to the increase in the cost of manufacturing the tights.
On connaît d'après le document US-4.440.140 un dispositif de transfert pour transférer automatiquement les bas d'une machine à coudre les collants à une machine à coudre les pointes qui comprend un élément en forme de L comportant un bras horizontal avec une paire d'étriers écartés en forme de U pour écarter latéralement les jambes du collant pendant le transfert et une paire de crochets pour enlever le collant des formes correspondantes de la machine à coudre les collants, le faire tourner de 90° et ensuite pour effectuer son chargement retourné sur les tubes d'aspiration de la machine à coudre les pointes.
Mais ce dispositif connu impose que la machine à coudre les collants soit équipée de plusieurs paires d'étriers en forme de U de dimensions, forme et écartement similaires aux étriers dudit bras horizontal du dispositif de transfert.
Par ailleurs, il est nécessaire que, durant cette opération, un opérateur charge chaque pièce l'une après l'autre comme dans la machine à coudre les collants et ensuite divise latéralement les jambes et les pieds de chaque paire de bas qui pendent librement vers le bas.
De plus, le transfert du collant de la machine à coudre les collants à la machine à coudre les pointes comporte une phase dans laquelle les jambes et les pieds du collant sont transférés et retenus dans la machine à coudre les pointes et le corps du collant est retenu dans la machine à coudre les collants.Document US-4,440,140 discloses a transfer device for automatically transferring the stockings from a pantyhose sewing machine to a spike sewing machine which comprises an L-shaped element comprising a horizontal arm with a pair of U-shaped stirrups to laterally spread the legs of the pantyhose during transfer and a pair of hooks to remove the pantyhose from the corresponding shapes of the pantyhose sewing machine, rotate it 90 ° and then to perform its load returned to the needle sewing machine suction tubes.
But this known device requires that the pantyhose sewing machine is equipped with several pairs of U-shaped stirrups of dimensions, shape and spacing similar to the stirrups of said horizontal arm of the transfer device.
Furthermore, it is necessary that, during this operation, an operator loads each piece one after the other as in the sewing machine for tights and then laterally divides the legs and feet of each pair of stockings which hang freely towards the bottom.
In addition, the transfer of the pantyhose from the sewing machine to the machine pointe shoes has a phase in which the legs and feet of the pantyhose are transferred and retained in the sewing machine the spikes and the body of the pantyhose is retained in the pantyhose sewing machine.
Le but principal de la présente invention est d'éliminer les inconvénients mentionnés et de proposer un procédé et un dispositif pour le transfert automatique des collants d'une machine à coudre les collants à une machine qui effectue la couture de la pointe des pieds.The main object of the present invention is to eliminate the drawbacks mentioned and to provide a method and a device for the automatic transfer of the tights from a pantyhose sewing machine to a machine which performs the tiptoeing.

Avantageusement, ladite plaque (8) est montée pivotante autour d'un axe horizontal dudit bras (7) au moyen d'une crémaillère et d'un organe moteur correspondant (non représenté sur le dessin par simplification) pour pouvoir prendre, durant la course active aller du chariot (70), une position horizontale et, durant la course de retour à vide, une position verticale, c'est-à-dire pivotée de 90° dans le sens contraire des aiguilles d'une montre. Selon une forme alternative de réalisation de l'invention, le tube (25) desdits moyens d'aspiration (200) est fixe, c'est-à-dire non extractible.Advantageously, said plate (8) is pivotally mounted about a horizontal axis of said arm (7) by means of a rack and a corresponding motor member (not shown in the drawing for simplification) in order to be able to take, during the race active go from the carriage (70), a horizontal position and, during the empty return stroke, a vertical position, that is to say rotated 90 ° counterclockwise. According to an alternative embodiment of the invention, the tube (25) of said suction means (200) is fixed, that is to say non-extractable.
Le fonctionnement du dispositif est le suivant.
Alors qu'un collant (1) se trouve dans la station et dans la position de déchargement de la machine à coudre les collants, le tube (25) situé au-dessous est placé dans la position d'extraction, c'est-à-dire soulevé, et l'aspiration de l'air est activée de manière à permettre l'attraction des jambes (100) du collant (1) dans la chambre (24) et obtenir ainsi un léger étirement. Lorsque l'aspiration pneumatique a cessé, le tube (25) est rétracté en découvrant les jambes (100) du collant (1) ainsi allongées et le corps (30) est prélevé par la pince (16) laquelle, successivement, dépasse les crochets (6) en s'y arrêtant. A ce point, la pointe mobile (160') de la pince (16) étend horizontalement le bord (30) du corps (3), de manière que les crochets (6) puissent l'accrocher et l'écarter verticalement. Après l'écartement du bord (30), les crochets (62) prélèvent le corps (3) pour l'enfiler sur les tubes (9) de la machine à coudre les pointes (90) en le retournant, après quoi le chariot (161), avec la pince (16), recule. Simultanément, le chariot (70), avec la plaque (8) placée dans la position horizontale et derrière le collant (1), de manière que chaque jambe (100) du collant (1) se loge dans une entaille (81) correspondante de celle-ci (8), est commandé pour avancer et la course en avant du chariot (70) entraîne l'avance et le soulèvement des jambes (100), de manière que, en fin de course, les extrémités (101) du collant (1) se trouvent en face de l'embouchure des tubes de retournement (9) de la machine à coudre les pointes pour être aspirées dans ceux-ci. Successivement, la plaque (8) est pivotée de 90° dans le sens contraire des aiguilles d'une montre et ramenée dans sa position initiale par le chariot (70) et, dans cette position, avec une rotation 90° dans le sens des aiguilles d'une montre, elle est ramenée dans la position horizontale de service, tandis que le tube (25) est de nouveau extrait pour traiter le collant successif qui se trouve dans la station de déchargement de la machine à coudre les collants.The operation of the device is as follows.
While a pantyhose (1) is in the station and in the unloading position of the pantyhose sewing machine, the tube (25) located below is placed in the extraction position, i.e. -to say raised, and the air suction is activated so as to allow the attraction of the legs (100) of the pantyhose (1) in the chamber (24) and thus obtain a slight stretching. When the pneumatic aspiration ceased, the tube (25) is retracted by uncovering the legs (100) of the pantyhose (1) thus elongated and the body (30) is removed by the clamp (16) which, successively, exceeds the hooks ( 6) by stopping there. At this point, the movable point (160 ') of the pliers (16) extends horizontally the edge (30) of the body (3), so that the hooks (6) can hang on and move it vertically. After the spacing of the edge (30), the hooks (62) take the body (3) to thread it on the tubes (9) of the stitch sewing machine (90) by turning it over, after which the carriage ( 161), with the pliers (16), move back. Simultaneously, the carriage (70), with the plate (8) placed in the horizontal position and behind the pantyhose (1), so that each leg (100) of the pantyhose (1) is housed in a notch (81) corresponding to the latter (8) is controlled to advance and the stroke in front of the carriage (70) causes the legs (100) to advance and lift, so that, at the end of the stroke, the ends (101) of the tights (1) are located opposite the mouth of the turning tubes (9) of the needle sewing machine to be sucked into them. Subsequently, the plate (8) is pivoted 90 ° anti-clockwise and brought back to its initial position by the carriage (70) and, in this position, with a 90 ° rotation in the clockwise direction of a watch, it is brought back to the horizontal service position, while the tube (25) is again extracted to treat the sticky which is in the unloading station of the pantyhose sewing machine.
