Description
L'invention concerne un dispositif pour raidir le bord à coudre au soufflet des collants avec alimentation automatisée.The invention relates to a device for stiffening the edge to be sewn to the bellows of tights with automated feeding.
On connaît d'après le brevet GB-A-2 040 157 une machine à coudre les soufflets des collants comprenant un carrousel muni de plusieurs bras portant chacun un support tubulaire rotatif à axe vertical et embouchure horizontale et en communication vers le haut avec des moyens d'aspiration, chaque support étant positionnable dans une pluralité de stations pour, successivement : placer et orienter manuellement le bord de l'ouverture laissée sans couture autour de l'embouchure du support avec le corps et les jambes du collant suspendus, aspirer le corps avec les jambes à l'intérieur dans ledit support, disposer un soufflet contre ladite embouchure et ledit bord à coudre, couper l'excédent de tissu et coudre le soufflet et ledit bord du collant par rotation dudit support. Une telle machine présente l'inconvénient majeur de nécessiter la mise en place et l'orientation manuelle du collant sur le support tubulaire, opération qui, constitue une considérable perte de temps.GB-A-2 040 157 discloses a machine for sewing the bellows of tights comprising a carousel provided with several arms each carrying a rotary tubular support with vertical axis and horizontal mouth and in upward communication with means suction, each support being positionable in a plurality of stations for, successively: manually placing and orienting the edge of the opening left seamless around the mouth of the support with the body and the legs of the pantyhose hanging, sucking the body with the legs inside in said support, place a bellows against said mouth and said sewing edge, cut the excess fabric and sew the bellows and said edge of the pantyhose by rotating said support. Such a machine has the major drawback of requiring the fitting and manual orientation of the tights on the tubular support, an operation which constitutes a considerable loss of time.
Une solution à ce problème d'automatisation a été proposée dans le brevet EP-A-0 070 813, en utilisant un dispositif pour le transfert automatique des collants d'une machine à fabriquer les collants avec couture à une machine à coudre les soufflets, comprenant des moyens de maintien du corps du collant sur la machine à coudre les collants, deux tuyaux verticaux d'aspiration pneumatique pour maintenir séparées les jambes du collant et rendre accessible l'ouverture périnéale, des moyens de prise du vêtement par ladite ouverture, des moyens de transfert des moyens de prise avec le collant relaché suspendu jusqu'au support tubulaire à axe vertical et ouverture horizontale de la machine à coudre les soufflets pour placer l'ouverture périnéale du collant autour de ladite embouchure et aspirer le corps et les jambes du collant à l'intérieur dudit support. L'expérience a démontré qu'avec certains types de tissu, spécialement des collants de longueur et finesse notables, des fronces se forment sur le pourtour de l'ouverture périnéale du collant au moment de sa mise en place sur le support de la machine à coudre les soufflets et de l'aspiration du corps et des jambes du collant dans ledit support.A solution to this automation problem has been proposed in patent EP-A-0 070 813, by using a device for the automatic transfer of the tights from a machine for manufacturing the tights with seam to a gusset sewing machine, comprising means for holding the body of the pantyhose on the pantyhose sewing machine, two vertical pneumatic suction pipes for keeping the legs of the pantyhose separate and making the perineal opening accessible, means for taking the garment through said opening, means for transferring the gripping means with the released pantyhose suspended up to the tubular support with vertical axis and horizontal opening of the bellows sewing machine to place the perineal opening of the pantyhose around said mouth and suck the body and legs of the sticky inside said support. Experience has shown that with certain types of fabric, especially tights of considerable length and finesse, gathers are formed around the perineal opening of the tights when it is placed on the support of the sew the bellows and the suction of the body and legs of the pantyhose into said support.
Le but principal de la présente invention est d'éliminer ces inconvénients.The main object of the present invention is to eliminate these drawbacks.
Un but ultérieur de l'invention est de réduire le temps pour le transfert du vêtement du dispositif d'alimentation et pour son positionnement correct dans la tête de la machine à coudre les soufflets.A further aim of the invention is to reduce the time for transferring the garment from the feed device and for its correct positioning in the head of the bellows sewing machine.
On est parvenu à ces résultats en conformité de l'invention en adoptant l'idée de recueillir, par aspiration, dans un seul tuyau au-dessous de la tête et mobile verticalement, coaxialement à elle-même, le corps et les jambes du collant tandis qu'il est retenu suspendu de la tête elle-même, ensuite d'approcher le dit tuyau jusqu'à toucher avec son extrémité supérieure l'embouchure de la dite tête, en y repliant et en y bloquant le tissu interposé et enfin d'aspirer dans la tête le corps et successivement les jambes ; à cela coopérant des moyens pour approcher et guider le collant, encore suspendu du dispositif d'alimentation, à la bouche du dit tuyau de ramassage et moyens pour faciliter, en majorant, l'aspiration du collant du dit tuyau de ramassage dans la dite tête.These results have been achieved in accordance with the invention by adopting the idea of collecting, by suction, in a single pipe below the head and movable vertically, coaxially to itself, the body and the legs of the pantyhose. while it is retained suspended from the head itself, then to approach the said pipe until touching with its upper end the mouth of the said head, by folding over and blocking the interposed tissue therein and finally d '' suck in the head the body and successively the legs; cooperating means for approaching and guiding the pantyhose, still suspended from the supply device, at the mouth of said collecting pipe and means for facilitating, by increasing, the suction of the pantyhose from said collecting pipe into said head .
Les avantages obtenus grâce à la présente invention consistent essentiellement dans le fait qu'on obtient le transfert du collant sur la machine à coudre les soufflets sans formation de grimaces dans la zone du tissu adhérente à la tête et cela avec n'importe quelle longueur et finesse du tissu ; qu'on atteint une vitesse du transfert du collant sur la machine à coudre les soufflets assez plus grande que celle obtenue jusqu'aujourd'hui ; qu'on a une précision et fiabilité de fonctionnement très élevées même pour des périodes de temps très longues.The advantages obtained thanks to the present invention essentially consist in the fact that the sticky transfer is obtained on the bellows sewing machine without the formation of grimaces in the area of the tissue adhering to the head and this with any length and fineness of the fabric; that a speed of transfer of the tights to the bellows sewing machine is reached which is much greater than that obtained to date; that we have very high operating precision and reliability even for very long periods of time.

- - un tuyau (2) vertical, de ramassage du collant, positionné coaxialement sous la tête (4), mobile verticalement et pourvu de moyens d'aspiration pneumatique vers le bas et moyens de blocage (22) des jambes (36) du collant ; à l'intérieur du dit tuyau (2) il y a un manchon (21) réglable et interchangeable, saillant de la bouche du tuyau (2) et ayant les fonctions de réduire la section de contenance du collant en augmentant la vitesse de l'air y aspiré et en outre de pénétrer, avec son sommet, dans l'embouchure (40) de la tête (4) et ainsi de replier en y bloquant le tissu (34) interposé. Pour favoriser l'aspiration du collant du manchon (21) à la tête (4), une lumière (20) est prévue dans la surface du tuyau (2) à une cote inférieure à la base du manchon (21) lorsque ce dernier est soulevé, laquelle lumière est ouverte, par des moyens connus, dès que l'aspiration dans la tête (4) marque son début.
- - Un panier (3) avec profil en plan à forme de V, fixé à côté du prédit tuyau (2) de ramassage et dans la zone plus étroite duquel se ramassent spontanément les jambes (36) et le corps (35) du collant.
- - Un levier falciforme (5), asservi, avec des moyens connus, à un mouvement horizontal alternatif au sommet du dit panier (3) avec la fonction de déplacer et guider, avec une seule course, les jambes et le corps du collant au-dessus de la bouche du tuyau (2) et ainsi en faciliter l'aspiration dans son intérieur.
- - a vertical hose (2) for collecting the pantyhose, positioned coaxially under the head (4), movable vertically and provided with pneumatic suction means downwards and means for blocking (22) the legs (36) of the pantyhose; inside said pipe (2) there is an adjustable and interchangeable sleeve (21), protruding from the mouth of the pipe (2) and having the functions of reducing the capacity section of the pantyhose by increasing the speed of the air sucked in there and further penetrate, with its apex, into the mouth (40) of the head (4) and thus fold back by blocking the tissue (34) therein. To promote the suction of the tights from the sleeve (21) to the head (4), a light (20) is provided in the surface of the pipe (2) at a dimension lower than the base of the sleeve (21) when the latter is raised, which light is opened, by known means, as soon as the suction in the head (4) marks its beginning.
- - A basket (3) with a V-shaped profile in plan, fixed next to the aforesaid collecting pipe (2) and in the narrower zone from which the legs (36) and the body (35) of the pantyhose are spontaneously collected.
- - A sickle-shaped lever (5), subject, with known means, to an alternative horizontal movement at the top of said basket (3) with the function of moving and guiding, with a single stroke, the legs and the body of the pantyhose to- above the mouth of the pipe (2) and thus facilitate its suction inside.
Le fonctionnement est le suivant. Lorsque le dispositif (9) d'alimentation, portant suspendu le collant, se positionne coaxialement autour de la tête (4) de la machine à coudre les soufflets, les jambes (36) et le corps (35) du collant se disposent dans le panier (3), le levier (5) les déplace sur la bouche du tuyau (2) ; successivement le tuyau (2) se soulève pendant que les jambes (36) sont retenues par la pince (22) et le corps (35) est aspiré dans la tête (4) ; lorsque le sommet du tuyau (2) atteint l'embouchure (40) de la tête (4) le sommet du manchon (21) replie et bloque dans la dite embouchure (40) le tissu (34) interposé ainsi raidi ; enfin les jambes (36) aussi sont aspirées dans la tête (4).The operation is as follows. When the feeding device (9), hanging the pantyhose, is positioned coaxially around the head (4) of the bellows sewing machine, the legs (36) and the body (35) of the pantyhose are arranged in the basket (3), the lever (5) moves them over the mouth of the pipe (2); successively the pipe (2) lifts while the legs (36) are retained by the clamp (22) and the body (35) is sucked into the head (4); when the top of the pipe (2) reaches the mouth (40) of the head (4) the top of the sleeve (21) folds back and blocks in said mouth (40) the fabric (34) interposed thus stiffened; finally the legs (36) are also sucked into the head (4).
