Description

La présente invention a pour objet une machine pour la couture automatique de la pointe du pied de deux bas simultanément, et en particulier des collants.The present invention relates to a machine for the automatic sewing of the toe of two stockings simultaneously, and in particular tights.

On connaît d'après le brevet EP 136.391 du même titulaire, une machine pour la couture automatique de la pointe du pied des collants avec deux machines à coudre prévues dans deux stations distinctes, lesquelles effectuent la couture de la pointe du bas droit et respectivement du bas gauche de deux collants distincts simultanément.Is known from patent EP 136,391 of the same holder, a machine for the automatic sewing of the point of the tights with two sewing machines provided in two separate stations, which carry out the sewing of the point of the bottom right and respectively of the bottom left of two separate tights simultaneously.

L'expérience a démontré que la réduction draconienne du temps de couture de la pointe du pied des collants obtenue à l'aide de deux machines à coudre, s'avère fortement pénalisée si cette machine est reliée en amont, ou respectivement en aval, avec une autre machine qui présente un temps de cycle plus long, comme par exemple une machine qui produit les collants ou respectivement qui coud le soufflet des collants.Experience has shown that the drastic reduction in the sewing time of the toe of pantyhose obtained using two sewing machines proves to be greatly penalized if this machine is connected upstream, or respectively downstream, with another machine which has a longer cycle time, such as a machine which produces the tights or respectively which sews the bellows of the tights.

La présente invention a pour but principal de réaliser une machine pour la couture de la pointe des pieds des collants qui puisse être avantageusement reliée en amont, avec une machine qui produit les collants et/ou en aval, avec une machine qui coud le soufflet des collants.The main object of the present invention is to provide a machine for sewing the toes of the tights which can be advantageously connected upstream, with a machine which produces the tights and / or downstream, with a machine which sews the bellows of the tights.

Ces résultats ont été atteints conformément à l'invention en adoptant l'idée d'utiliser une machine avec des moyens à carrousel horizontal pour supporter les bas par paire sur deux tubes à retourner les bas, parallèles et munis d'ailettes coulissantes pour l'extraction de la pointe à coudre, et comprenant:

  • des moyens pour bloquer et pour redresser et aligner provisoirement le bord des pointes à coudre;
  • des moyens pour bloquer la pointe des deux bas avec le bord ainsi redressé et aligné sur un plan de couture et pour les transférer, par glissement, sur une machine à coudre;
  • des moyens pour désenfiler des tubes à retourner les bas une portion de chaque bas destinée à faciliter ledit transfert.
These results were achieved in accordance with the invention by adopting the idea of using a machine with horizontal carousel means for supporting the stockings in pairs on two tubes for turning the stockings, parallel and provided with sliding fins for the extraction of the sewing point, and comprising:
  • means for blocking and temporarily straightening and aligning the edge of the sewing points;
  • means for blocking the point of the two stockings with the edge thus straightened and aligned on a seam plane and for transferring them, by sliding, to a sewing machine;
  • means for unthreading tubes to return the stockings a portion of each stocking intended to facilitate said transfer.

Les avantages obtenus grâce à la présente invention consistent essentiellement en ce qu'il est possible de déformer provisoirement la pointe des deux bas de manière à obtenir un profil rectiligne correspondant à la ligne de couture à effectuer; que ledit bord à profil rectiligne d'un bas se trouve sur le prolongement du bord, ayant le même profil, de l'autre bas; qu'il est possible de soumettre ledit profil rectiligne provisoire des deux bas à une tension préalable et variable du tissu en correspondance de la pointe en fonction du rayon de courbure qu'on désire obtenir pour la pointe du bas après la couture; qu'il est possible de transférer en alignement ledit bord à profil provisoire rectiligne de deux bas séparés ou appartenant à un même produit manufacturé, c'est-à-dire un collant, des tubes à retourner les bas correspondants vers et jusqu'à la machine à coudre qui effectue la couture successivement.The advantages obtained thanks to the present invention essentially consist in the fact that it is possible to temporarily deform the tip of the two bottoms so as to obtain a rectilinear profile corresponding to the seam line to be made; that said straight profile edge of a bottom is on the extension of the edge, having the same profile, of the other bottom; that it is possible to subject said provisional rectilinear profile of the two stockings to a prior and variable tension of the fabric in correspondence of the point according to the radius of curvature which it is desired to obtain for the bottom point after sewing; that it is possible to transfer in alignment said edge with a rectilinear provisional profile of two separate stockings or belonging to the same manufactured product, that is to say sticky, tubes to return the corresponding stockings to and up to the sewing machine which sews successively.

Réduit à sa structure essentielle et en référence aux figures des dessins annexés, une machine pour la couture automatique de la pointe du pied de deux bas simultanément, en particulier des collants, comprend:

  • des moyens pour supporter plusieurs bas 3 par paire sur des tubes à retourner les bas horizontaux 1 correspondants, munis d'ailettes latérales 10 destinées à l'extraction de la pointe à coudre, du type à carrousel tournant par intermittence autour d'un axe vertical et avec arrêt dans la station de couture comme déjà décrit dans le brevet EP 136.391;
  • des moyens pour bloquer et déformer provisoirement, c'est-à-dire redresser et aligner, le profil de la pointe 30 du pied des deux bas avec une pince 4 pour chaque bas, dont les mâchoires sont constituées par deux éléments 40 à géométrie variable, oscillants horizontalement par commande d'un cylindre pneumatique 42 à course variable au moyen de contacts de fin de course réglables, et reliés entre eux par une barrette de caoutchouc 41 pour permettre de saisir les zone latérales de la pointe 30 et simultanément tirer en arrière sa zone médiane jusqu'à obtention d'un profil rectiligne, perpendiculaire à l'axe longitudinal des tubes 1: un extenseur à palette 5 à mouvement vertical alternatif, obtenu au moyen d'un cylindre pneumatique 50, agissant vers le bas sur ladite zone médiane de la pointe de chaque bas pour en faciliter ledit recul;
  • des moyens de blocage de la pointe des deux bas avec le profil ainsi modifié sur un plan horizontal fixe 6 de couture et un élément presseur à lame 7, situé au-dessus, à mouvement vertical alternif pour engager les deux pointes à coudre sur ledit plan et avec un mouvement horizontal alternatif pour les transférer ensemble par glissement sur une machine à coudre 8 dont l'aiguille verticale 80 effleure le bord du plan 6.
    Ledit élément presseur 7 est coulissant parallèlement au plan 6 dans un bras 70 qui supporte également les rouages 71,72 qui transmettent le mouvement horizontal à l'élément presseur 7, alors qu'une bielle 43 commande, par l'intermédiaire de la colonne 74, le mouvement vertical. A ce bras 70 sont également associés les deux extenseurs 5;
  • des moyens pour assister le transfert des pointes de bas à coudre de la zone en face des tubes à retourner les bas respectifs 1 jusqu'à la machine à coudre 8 avec un élément pousseur 9 pour chaque bas, lequel, en appuyant sur le tissu au-dessous de chaque ailette 10 et en se déplaçant parallèlement à celle-ci jusqu'à son extrémité libre, permet de désenfiler du tube correspondant 1 une portion de bas correspondante: les deux pousseurs 9 étant montés, tournant dans un plan vertical, sur un bras 90 transversal par rapport aux tubes 1 et qui est solidaire d'un coulisseau 91 coulissant sur un guide 92 sous la commande d'un cylindre pneumatique 93 et deux cames 94,95, une de fin de course aller, c'est-à-dire avec le bas en prise, et l'autre de fin de course retour, c'est-à-dire à vide, qui commandent la rotation des pousseurs 9 de la position soulevée, c'est-à-dire de travail, à celle abaissée, c'est-à-dire de repos, et inversement.
Reduced to its essential structure and with reference to the figures of the accompanying drawings, a machine for the automatic sewing of the toe of two stockings simultaneously, in particular tights, comprises:
  • means for supporting several stockings 3 per pair on tubes to turn over the corresponding horizontal stockings 1, provided with lateral fins 10 intended for the extraction of the sewing tip, of the carousel type rotating intermittently around a vertical axis and with stop in the sewing station as already described in patent EP 136,391;
  • means for temporarily blocking and deforming, that is to say straightening and aligning, the profile of the tip 30 of the foot of the two stockings with a clamp 4 for each stocking, the jaws of which consist of two elements 40 with geometry variable, oscillating horizontally by controlling a pneumatic cylinder 42 with variable stroke by means of adjustable limit switch contacts, and interconnected by a rubber bar 41 to enable the lateral zones of the tip 30 to be grasped and simultaneously pull in behind its middle zone until a straight profile is obtained, perpendicular to the longitudinal axis of the tubes 1: a pallet expander 5 with alternating vertical movement, obtained by means of a pneumatic cylinder 50, acting downwards on said median zone of the tip of each stocking to facilitate said recoil;
  • means for blocking the tip of the two bottoms with the profile thus modified on a fixed horizontal seam plane 6 and a blade presser element 7, located above, with alternating vertical movement for engaging the two sewing points on said plane and with an alternative horizontal movement to transfer them together by sliding on a sewing machine 8, the vertical needle 80 of which touches the edge of the plane 6.
    Said pressing element 7 is sliding parallel to the plane 6 in an arm 70 which also supports the cogs 71, 72 which transmit the horizontal movement to the pressing element 7, while a connecting rod 43 controls, via the column 74 , the vertical movement. To this arm 70 are also associated the two expanders 5;
  • means to assist the transfer of sewing stocking tips from the area in front of the tubes to return the respective stockings 1 to the sewing machine 8 with a pusher element 9 for each stocking, which, by pressing on the fabric below each fin 10 and moving parallel to it until its end free, makes it possible to thread from the corresponding tube 1 a corresponding bottom portion: the two pushers 9 being mounted, rotating in a vertical plane, on an arm 90 transverse to the tubes 1 and which is integral with a slide 91 sliding on a guide 92 under the control of a pneumatic cylinder 93 and two cams 94,95, one for end of travel limit, that is to say with the bottom in engagement, and the other for end of return travel, it that is to say when empty, which control the rotation of the pushers 9 from the raised position, that is to say working, to that lowered, that is to say at rest, and vice versa.

Le fonctionnement est le suivant. Lorsqu'un bras du carrousel, avec une paire de tubes à retourner les bas 1 portant les bas respectifs 3, arrive et s'arrête dans la station de couture, les ailettes 10 avancent ou sont déjà en avant de manière connue au-delà de l'extrémité libre des tubes 1 de manière que les zones de pointe 30 des bas viennent se positionner dans la bouche ouverte des pinces 4 (voir Fig. 1); après quoi les mâchoires 40 des pinces 4 sont refermées et les ailettes 10 reculent de manière que les zones de pointe 30 des bas restent bloquées entre les mâchoires 40. Ensuite, alors que les pinces 4 s'abaissent sous l'action de la bielle 73 qui agit sur le support 44 jusqu'à amener les zones de pointe des bas sur le plan de couture 6, les mâchoires 40 sont pivotées vers les tubes à retourner les bas, pendant que les extenseurs à palette 5 poussent vers le bas la partie médiane des zones de pointe 30, de manière que les barrettes 41, avec le bord de la pointe du bas interposée, se trouvent alignées dans la direction perpendiculaire à l'axe des tubes 1 en correspondance du bord du plan de couture 6 et que le tissu de la zone de pointe des bas subit une déformation élastique correspondante, c'est-à-dire une traction à caractère provisoire (voir Fig. 8). Le presseur à lame 7 est alors abaissé et bloque les deux zones de pointe 30 avec les bords à coudre correspondants alignés, et les mâchoires des pinces 4 sont écartées (voir Fig. 7).
Enfin, pendant que les pousseurs 9 désenfilent des tubes 1 une portion de bas correspondante, le presseur 7 revient en arrière vers la machine à coudre 8 en faisant glisser sur le plan de couture 6 les deux zones de pointe 30 des bas 3 et en passant devant l'aiguille 80 de la machine à coudre 8, au-delà de laquelle ces zones sont libérées. Au terme de la couture et après avoir été libérées de la prise du presseur 7, les zones de pointe 30 des bas perdent leur déformation élastique précédemment imposée par les pinces 4 et maintenue par le presseur 7, en reprenant la configuration naturelle du tissu, et la ligne de couture adopte un profil curviligne avec la convexité vers l'extérieur ou mixtiligne et dont la flèche est variable en fonction de la rotation plus ou moins importante imposée aux mâchoires 40 et de la traction subie par la zone médiane sous l'action des extenseurs à palette 5.The operation is as follows. When an arm of the carousel, with a pair of tubes for turning the stockings 1 carrying the respective stockings 3, arrives and stops in the sewing station, the fins 10 advance or are already forward in a known manner beyond the free end of the tubes 1 so that the tip regions 30 of the stockings are positioned in the open mouth of the clamps 4 (see FIG. 1); after which the jaws 40 of the clamps 4 are closed and the fins 10 move back so that the point areas 30 of the bottoms remain blocked between the jaws 40. Then, while the clamps 4 lower under the action of the rod 73 which acts on the support 44 up to bring the tip areas of the stockings to the seam plane 6, the jaws 40 are pivoted towards the tubes to turn the stockings, while the pallet expanders 5 push down the middle part of the tip areas 30, so that the bars 41, with the edge of the bottom point interposed, are aligned in the direction perpendicular to the axis of the tubes 1 in correspondence with the edge of the seam plane 6 and that the fabric of the bottom tip area undergoes a corresponding elastic deformation, that is to say a temporary pull (see Fig. 8). The blade presser 7 is then lowered and blocks the two tip zones 30 with the corresponding sewing edges aligned, and the jaws of the pliers 4 are moved apart (see FIG. 7).
Finally, while the pushers 9 thread a corresponding portion of stockings from the tubes 1, the presser 7 returns back to the sewing machine 8 by sliding the two tip areas 30 of the stockings 3 on the seam plane 6 and passing in front of the needle 80 of the sewing machine 8, beyond which these zones are released. At the end of the seam and after being released from the grip of the presser 7, the tip zones 30 of the stockings lose their elastic deformation previously imposed by the clamps 4 and maintained by the presser 7, resuming the natural configuration of the fabric, and the seam line adopts a curvilinear profile with convexity towards the outside or mixtilinear and whose arrow is variable according to the more or less important rotation imposed on the jaws 40 and of the traction undergone by the middle zone under the action of the pallet expanders 5.
