Abstract
Description
La présente invention a pour objet un procédé et une machine pour la couture automatique de deux bas pour former un collant.The present invention relates to a method and a machine for the automatic sewing of two stockings to form a pantyhose.
On connaît, d'après le brevet italien FI 91 A 232 du même titulaire, une machine pour la couture automatique de deux bas pour former un collant, laquelle comprend: des moyens à carrousel tournant horizontalement par intermittence, avec plusieurs formes plates, jumelées, de support des bas, ces formes étant solidaires l'une de l'autre et entraînées conjointement au moyen d'un organe de support correspondant et fixes par rapport aux moyens de couture des bas durant l'exécution de chaque phase opérationnelle; des moyens de positionnement et de déplacement des bas sur les formes de support respectives; des moyens pour la coupe longitudinale des corps des bas; des moyens pour la couture des bords alignés deux par deux des corps des deux bas ainsi découpés, avec deux machines à coudre mobiles, chacune desquelles exécute la couture d'union d'une paire correspondante de bords de tissu.We know, from Italian patent FI 91 A 232 of the same owner, a machine for the automatic sewing of two stockings to form a pantyhose, which comprises: carousel means rotating horizontally intermittently, with several flat shapes, twinned, support stockings, these forms being integral with each other and driven jointly by means of a corresponding support member and fixed relative to the means of sewing stockings during the execution of each operational phase; means for positioning and moving the stockings on the respective support forms; means for the longitudinal cut of the stockings bodies; means for sewing the edges aligned two by two of the bodies of the two stockings thus cut, with two mobile sewing machines, each of which performs the union sewing of a corresponding pair of edges of fabric.
Mais l'expérience a démontré que, du fait que la couture réalisée en deux parties, lesquelles sont partiellement superposées en correspondance de la zone périnéale du corps, le collant fini assume un aspect extérieur peu agréable. A cela s'ajoute le fait que l'utilisation de deux machines à coudre entraîne une bonne augmentation du coût de fabrication et d'exploitation de ces machines connues, compte tenu du fait que le coût de chaque machine à coudre est considérable par rapport au coût d'ensemble de la machine.But experience has shown that, because the seam made in two parts, which are partially superimposed in correspondence of the perineal area of the body, the finished pantyhose assumes an unpleasant external appearance. Added to this is the fact that the use of two sewing machines leads to a good increase in the cost of manufacturing and operating these known machines, taking into account that the cost of each sewing machine is considerable compared to the overall cost of the machine.
Le but principal de la présente invention est d'éliminer les inconvénients mentionnés ci-dessus et de proposer un procédé et une machine pour former des collants qui permettent d'obtenir une seule couture d'union des bords découpés des bas et, en même temps, une bonne réduction du coût de fabrication et d'exploitation de la machine, tout en conservant la même capacité de production élevée.The main object of the present invention is to eliminate the drawbacks mentioned above and to provide a method and a machine for forming tights which make it possible to obtain a single union seam of the cut edges of the stockings and, at the same time , a good reduction in the cost of manufacturing and operating the machine, while maintaining the same high production capacity.
Ce résultat a été atteint, conformément à l'invention, en adoptant un procédé pour la couture automatique de deux bas pour former un collant, comprenant les phases suivantes:
- enfiler et positionner les deux bas sur des formes jumelées correspondantes de support; effectuer la coupe longitudinale d'une même longueur des corps des bas ainsi positionnés; écarter les formes précitées avec les corps des bas ainsi découpés et effectuer la couture des bords de tissu dépassant des formes ainsi écartées; dans lequel ladite couture est unique, c'est-à-dire réalisée sans solution de continuité pour les deux paires de bords de tissu durant toute la phase de couture et effectuée avec les formes correspondantes asservies à un mouvement relatif d'avance à vitesse constante et continue, et dans lequel une ou plusieurs des phases précitées qui précèdent la couture sont réalisées avec l'arrêt des supports des formes pour permettre l'action des moyens opérationnels correspondants.This result was achieved, in accordance with the invention, by adopting a process for the automatic sewing of two stockings to form a pantyhose, comprising the following phases:
- thread and position the two stockings on corresponding twin support forms; make the longitudinal cut of the same length of the bodies of the stockings thus positioned; discard the aforementioned shapes with the bodies of the stockings thus cut out and sew the edges of the fabric protruding from the shapes thus separated; in which said sewing is unique, that is to say performed without a solution of continuity for the two pairs of fabric edges during the entire sewing phase and performed with the corresponding shapes slaved to a relative movement in advance at constant and continuous speed, and in which one or more of the above-mentioned phases which precede sewing are carried out with the stopping of the supports of the forms to allow the action of the corresponding operational means.
Et pour mettre en oeuvre ledit procédé, on utilise une machine à carrousel circulaire avec plusieurs formes plates jumelées de support de chaque paire de bas à unir, avec des moyens pour le positionnement et le déplacement des bas sur les formes respectives, avec des moyens pour la coupe longitudinale desdits corps, dans laquelle lesdites formes sont supportées individuellement par des palettes porte-formes correspondantes de manière à permettre leur entraînement séparément et à des vitesses différentes, dans laquelle une machine à coudre automatique est prévue, fixe en correspondance de la station de couture des bas, de manière à réaliser la couture unique, c'est-à-dire sans solution de continuité pour les deux paires de bords de tissu des corps ainsi découpés, et dans laquelle des moyens sont prévus pour l'entraînement à vitesse différenciée de chaque palette en correspondance de la station de couture par rapport à toutes les autres.And to implement said method, a circular carousel machine is used with several twin flat forms of support for each pair of stockings to be united, with means for positioning and displacement of the stockings on the respective forms, with means for the longitudinal section of said bodies, in which said forms are supported individually by corresponding form-carrying pallets so as to allow them to be driven separately and at different speeds, in which an automatic sewing machine is provided, fixed in correspondence of the station sewing of the stockings, so as to carry out the single seam, that is to say without solution of continuity for the two pairs of edges of fabric of the bodies thus cut, and in which means are provided for driving at differentiated speed of each pallet in correspondence of the sewing station with respect to all the others.
Les avantages obtenus grâce à la présente invention consistent essentiellement en ce qu'il est possible de réaliser la couture unique et continue des bords alignés des corps des deux bas à unir, c'est-à-dire sans solution de continuité, en assurant une capacité de production élevée et en conférant au collant un aspect extérieur agréable; en ce qu'il est possible de réduire sensiblement le coût de fabrication d'une machine pour former les collants ayant la même capacité de production, grâce à l'élimination d'une machine à coudre; en ce qu'une machine conformément à l'invention est très fiable, même après une longue période d'utilisation.The advantages obtained thanks to the present invention essentially consist in the fact that it is possible to carry out the single and continuous seam of the aligned edges of the bodies of the two stockings to be joined, that is to say without solution of continuity, by ensuring a high production capacity and giving the tights a pleasant external appearance; in that it is possible to significantly reduce the manufacturing cost of a machine for forming tights having the same production capacity, by eliminating a sewing machine; in that a machine according to the invention is very reliable, even after a long period of use.

Réduit à sa structure essentielle et en référence aux figures des dessins annexés, un procédé pour la couture automatique de deux bas pour former un collant, comprenant les phases suivantes:
- a) enfiler et positionner les deux bas sur des formes jumelées correspondantes de support (1);
- b) effectuer la coupe longitudinale d'une même longueur des corps des bas ainsi positionnés;
- c) écarter les formes (1) précitées avec les corps des bas ainsi découpés;
- d) effectuer la couture des bords de tissu dépassant des formes (1) ainsi écartées; conformément à l'invention, prévoit que ladite couture soit unique, c'est-à-dire réalisée sans solution de continuité pour les deux paires de bords de tissu et effectuée avec les formes (1) correspondantes asservies à un mouvement relatif continu d'avance à vitesse constante, et dans lequel une ou plusieurs des phases précitées (a,b,c) qui précèdent la phase (d) de couture sont effectuées avec l'arrêt des supports des formes (1) correspondantes pour permettre l'action des moyens opérationnels correspondants (c'est-à-dire de chargement, positionnement, coupe et ainsi de suite).
- a) thread and position the two stockings on corresponding twin support forms (1);
- b) make the longitudinal cut of the same length of the bodies of the stockings thus positioned;
- c) discard the aforementioned shapes (1) with the bodies of the stockings thus cut;
- d) sewing the edges of the fabric protruding from the shapes (1) thus separated; in accordance with the invention, provides that said seam is unique, that is to say made without solution of continuity for the two pairs of edges of fabric and made with the corresponding shapes (1) slaved to a continuous relative movement of advance at constant speed, and in which one or more of the above-mentioned phases (a, b, c) which precede the sewing phase (d) are carried out with the stopping of the supports of the corresponding shapes (1) to allow the action of the means corresponding operational (i.e. loading, positioning, cutting and so on).
Autrement dit, durant une ou plusieurs desdites phases (a,b,c), un ou plusieurs des supports des formes (1) peuvent être à l'arrêt, alors que tous les autres sont en mouvement.
Ainsi, par exemple, en prenant comme hypothèse le cas de cinq supports pour autant de formes (1), durant la phase (d) de couture, deux formes (1) avec les supports correspondants peuvent être arrêtées par rapport aux moyens d'entraînement correspondants et les trois autres en mouvement. Il va de soi que, en correspondance des formes (1) arrêtées, ce sont les moyens correspondants de traitement des bas qui se déplacent et inversement.In other words, during one or more of said phases (a, b, c), one or more of the supports of the forms (1) may be stopped, while all the others are in motion.
Thus, for example, assuming the case of five supports for as many forms (1), during the sewing phase (d), two forms (1) with the corresponding supports can be stopped with respect to the drive means correspondents and the other three in motion. It goes without saying that, in correspondence with the stopped shapes (1), it is the corresponding stocking processing means which move and vice versa.
Et pour mettre en oeuvre ledit procédé, on utilise une machine à carrousel circulaire avec cinq formes (1) plates jumelées de support de chaque paire de bas à unir, avec des moyens pour le positionnement et le déplacement des bas sur les formes respectives, avec des moyens pour la coupe longitudinale desdits corps, dans laquelle, conformément à l'invention, lesdites formes (1) sont supportées individuellement par des palettes porte-formes (2) correspondantes de manière à permettre leur entraînement séparément et à des vitesses différentes, dans laquelle une machine à coudre (3) automatique est prévue, fixe en correspondance de la station (S) de couture des bas, de manière à réaliser la couture unique, c'est-à-dire sans solution de continuité, des bords alignés des corps ainsi découpés, et dans laquelle des moyens sont prévus pour l'entraînement à vitesse différenciée de chaque palette (2) en correspondance de la station de couture (S) par rapport à toutes les autres.And to implement the said method, a circular carousel machine is used with five flat shapes (1) paired with support for each pair of stockings to be joined, with means for positioning and moving the stockings on the respective shapes, with means for the longitudinal cutting of said bodies, in which, in accordance with the invention, said forms (1) are supported individually by corresponding form-carrying pallets (2) so as to allow them to be driven separately and at different speeds, in which an automatic sewing machine (3) is provided, fixed in correspondence of the sewing station (S) bottom, so as to carry out the single seam, that is to say without solution of continuity, of the aligned edges of the bodies thus cut, and in which means are provided for driving at differentiated speed of each pallet (2) in correspondence of the sewing station (S) in relation to all the others.
Plus particulièrement, en référence à la Fig. 2 des dessins annexés, lesdits moyens d'entraînement des palettes (2) comprennent un secteur denté (4) en correspondance de la base de chaque palette (2), lequel possède un profil en arc de cercle, avec la concavité dirigée vers l'intérieur de la machine, et coopère avec un pignon (5) correspondant. Lesdits pignons (5) sont disposés aux sommets d'un hexagone régulier à l'intérieur de la machine et la distance entre deux pignons (5) consécutifs est environ égale à la corde de l'arc de cercle précité, de manière à permettre l'entraînement des palettes (2) quelle que soit leur position angulaire. Et, pour permettre l'entraînement à vitesse différenciée de la palette (2) en correspondance de la station de couture par rapport aux autres palettes (2), chaque pignon (5) est relié à un organe moteur correspondant - par simplification non représenté sur le dessin - de manière que le pignon (5) de la station de couture et celui qui le suit dans la direction de la rotation du carrousel tournent à une vitesse constante et continue. Le développement angulaire de chaque secteur (4) est une fraction de l'angle d'un tour, de manière qu'une fraction (X) égale soit libre, c'est-à-dire ne coopérant avec aucun secteur (4).More particularly, with reference to FIG. 2 of the accompanying drawings, said means for driving the pallets (2) comprise a toothed sector (4) corresponding to the base of each pallet (2), which has a profile in an arc, with the concavity directed towards the inside the machine, and cooperates with a corresponding pinion (5). Said pinions (5) are arranged at the vertices of a regular hexagon inside the machine and the distance between two consecutive pinions (5) is approximately equal to the chord of the aforementioned arc, so as to allow the drive of the pallets (2) whatever their angular position. And, to allow the drive at different speed of the pallet (2) in correspondence of the sewing station with respect to the other pallets (2), each pinion (5) is connected to a corresponding drive member - by simplification not shown on the drawing - so that the pinion (5) of the sewing station and that which follows it in the direction of rotation of the carousel rotate at a constant and continuous speed. The angular development of each sector (4) is a fraction of the angle a turn, so that an equal fraction (X) is free, that is to say not cooperating with any sector (4).
Avantageusement, conformément à l'invention et en référence à la Fig. 2 des dessins annexés, lesdits moyens d'entraînement des palettes (2) comprennent deux transmissions à chaîne (6,7) à boucle fermée, dont une (6) est asservie à un organe moteur correspondant (60) et destinée à entraîner le pignon (5) en correspondance de la station de couture et celui placé immédiatement après, et l'autre (7) est asservie à un organe moteur correspondant (70) et destinée à entraîner les pignons (5) étrangers à la station de couture (S).Advantageously, in accordance with the invention and with reference to FIG. 2 of the accompanying drawings, said means for driving the pallets (2) comprise two chain transmissions (6,7) with closed loop, one of which (6) is slaved to a corresponding drive member (60) and intended to drive the pinion (5) in correspondence of the sewing station and that placed immediately after, and the other (7) is slaved to a corresponding drive member (70) and intended to drive the pinions (5) foreign to the sewing station (S ).
En alternative, en référence à la Fig. 3 des dessins annexés, lesdits moyens d'entraînement des palettes (2) comprennent une bielle (8) en correspondance de la base inférieure de chaque palette (2), laquelle, d'un côté, est articulée sur la base de la palette correspondante (2) et, de l'autre côté, coopère, dans la section comprise entre la station de chargement (C) et la station de couture (S), avec une chaîne de transmission correspondante (9) entraînée par un organe moteur (90) et coopère, dans la section en correspondance de la station de couture (S), avec une chaîne de transmission correspondante (10) entraînée par un organe moteur (11) tournant à une vitesse supérieure par rapport au moteur (90). De cette manière, on obtient l'entraînement à vitesse différenciée des palettes (2) dans la station de couture par rapport à celle de toutes les autres.Alternatively, with reference to FIG. 3 of the accompanying drawings, said means for driving the pallets (2) comprise a connecting rod (8) corresponding to the lower base of each pallet (2), which, on one side, is articulated on the base of the corresponding pallet (2) and, on the other side, cooperates, in the section between the loading station (C) and the sewing station (S), with a corresponding transmission chain (9) driven by a drive member (90 ) and cooperates, in the corresponding section of the sewing station (S), with a corresponding transmission chain (10) driven by a motor member (11) rotating at a higher speed relative to the motor (90). This way we get speed training differentiated from the pallets (2) in the sewing station compared to that of all the others.
Selon une autre alternative, en référence à la Fig. 10 des dessins annexés, lesdites palettes porte-formes (2) sont entraînées à vitesse différenciée, en relation avec les positions instantanées respectives, au moyen de deux chaînes d'entraînement (12, 13), chacune desquelles est supportée par un élément de guidage (120, 130) en technopolymère, dont une (12) est asservie à un organe moteur (121) correspondant et destinée à entraîner les palettes (2) des formes (1) qui sont en dehors de la station de couture (C) et l'autre (13) est asservie à un organe moteur (131) correspondant et destinée à entraîner les palettes (2) des formes (1) qui sont en correspondance de la station de couture (C) .According to another alternative, with reference to FIG. 10 of the accompanying drawings, said pallets (2) are driven at different speed, in relation to the respective instantaneous positions, by means of two drive chains (12, 13), each of which is supported by a guide element (120, 130) in technopolymer, one of which (12) is slaved to a corresponding drive member (121) and intended to drive the pallets (2) of the shapes (1) which are outside the sewing station (C) and the other (13) is slaved to a corresponding drive member (131) and intended to drive the pallets (2) of the shapes (1) which are in correspondence with the sewing station (C).
