Description

La présente invention concerne un procédé et une machine pour transférer automatiquement les collants, bas et chaussettes d'une machine qui en coud les pointes à une machine qui les repasse.The present invention relates to a method and a machine for automatically transferring tights, stockings and socks from a machine which sews the tips to a machine which passes them.

On connaît d'après le brevet européen n° 057.055 un dispositif de transfert des collants d'une machine à coudre les pointes du type à carrousel avec axe horizontal pourvu de plusieurs paires de tubes horizontaux, à une machine à repasser du type à carrousel avec axe vertical pourvu de plusieurs paires de formes plates horizontales, disposées en évantail, lesquelles sont pourvues de résistances thermiques et réalisées en outre en deux éléments articulés par charnière pour en permettre la fermeture du type livre. Ces deux machines sont positionnées réciproquement de telle manière que la station de chargement de la machine à repasser se trouve en face de la station de déchargement de la machine à coudre les pointes et avec une paire de formes de l'une coplanaire et alignée avec une paire de tubes de l'autre. Le dispositif de transfert proprement dit comprend un chariot, lequel est mobile horizontalement et alternativement entre lesdites stations des deux machines et pourvu de crochets pour engager par poussée le bord élastique du collant à transférer. Pendant la course dudit chariot vers la machine à repasser, le corps du collant est tout d'abord retourné et ensuite transporté jusqu' à ce qu' il s'enfile sur la paire de formes correspondante de la machine à repasser. Un tel dispositif de transfert présente l'inconvénient de ne permettre qu'un rythme de travail lent en raison de la course à vide du chariot transporteur et de constituer un système d'interaction rigide entre la machine qui coud les pointes et celle qui repasse les collants, ce qui a pour conséquence que l'arrêt de l'une d'elles entraîne l'arrêt forcé de l'autre, réduisant ainsi de manière draconienne le rendement de tout le système.A device for transferring tights from a carousel-type spike sewing machine with horizontal axis provided with several pairs of horizontal tubes to a carousel-type ironing machine is known from European patent No. 057.055. vertical axis provided with several pairs of horizontal flat shapes, arranged in a fan, which are provided with thermal resistances and further produced in two hinged elements to allow the closing of the book type. These two machines are positioned reciprocally so that the loading station of the ironing machine is located opposite the unloading station of the sewing machine and with a pair of shapes of one coplanar and aligned with a pair of tubes on the other. The transfer device proper comprises a carriage, which is movable horizontally and alternately between said stations of the two machines and provided with hooks to engage by pushing the elastic edge of the pantyhose to be transferred. During the course of said carriage towards the ironing machine, the body of the pantyhose is firstly turned over and then transported until it slides over the corresponding pair of shapes of the ironing machine. Such a transfer device has the disadvantage of only allowing a slow working rhythm due to the empty stroke of the transporting carriage and of constituting a rigid interaction system between the machine which sews the points and that which passes over the tights, which has the consequence that stopping one of them leads to the forced stopping of the other, thus drastically reducing the performance of the whole system.

En outre d'après le document BE-A-734244 on connaît une machine pour la confection de collants qui comprend un premier chariot, coulissant verticalement et pourvu de deux paires de plaquettes profilées pour suspendre deux bas, et un deuxième chariot, coulissant horizontalement et pourvu de deux paires de mâchoires escamotables pour mettre en contact les parties adjacentes supérieures des deux bas et ensuite permettre leur solidarisation. Mais avec ces dispositifs connus on ne peut pas manipuler un collant et en particulier on ne peut ni retourner le collant qui se présente à l'envers dans la station de déchargement d'une ordinaire machine à coudre les pointes, ni saisir le bord élastique du collant en l'élargissant et en l'orientant de façon convenable par rapport aux formes d'une machine à repasser, ni transférer le collant sur ladite machine à repasser.In addition, from document BE-A-734244, a machine for making tights is known which comprises a first carriage, sliding vertically and provided with two pairs of profiled plates for hanging two stockings, and a second carriage, sliding horizontally and provided with two pairs of retractable jaws to bring the upper adjacent parts of the two stockings into contact and then allow them to be joined. However, with these known devices, it is not possible to manipulate tights, and in particular neither to turn the tights which appear upside down in the unloading station of an ordinary stitch sewing machine, nor to grasp the elastic edge of the sticky by widening and orienting it in a suitable manner with respect to the shapes of an ironing machine, or transferring the sticky on said ironing machine.

Enfin d'après le document EP-A-0136391 on connaît une machine à coudre les bouts des collants qui comprend un dispositif de prise, à travers la zone ouverte de la ceinture, et de transport du vêtement qui renverse le corps du collant par l'extension des moyens de prises en deux directions orthogonales et le positionnement du corps sur deux cannes dans lesquelles l'aspiration des jambes est opérée. Mais un tel dispositif ne permet pas un complet renversement du collant ni l'orientation de son bord élastique.Finally, according to document EP-A-0136391, a machine is known for sewing the ends of the tights which comprises a device for gripping, through the open area of the belt, and for transporting the garment which overturns the body of the tights by extension of the gripping means in two orthogonal directions and the positioning of the body on two rods in which the suction of the legs is operated. But such a device does not allow complete reversal of the tights or the orientation of its elastic edge.

La présente invention a pour but d'éliminer les inconvénients du dispositif évoqué ci-dessus, en réalisant une machine qui transfert les collants, bas et chaussettes, d'une machine qui coud les pointes du type à carrousel avec axe vertical, à une machine à repasser du type pourvu d'une paire de formes verticales fixes, et qui permette de rendre indépendant le fonctionnement de chacune desdites machines du fait que l'on prévoit le chargement manuel de la machine de transfert en cas d'arrêt de la machine à coudre les pointes et la possibilité de décharger les collants de la machine à coudre les pointes dans un magasin de stockage et récupération, en cas d'arrêt de la machine à repasser.The present invention aims to eliminate the drawbacks of the device mentioned above, by making a machine which transfers the tights, stockings and socks, from a machine which sews the tips of the carousel type with vertical axis, to a machine ironing of the type provided with a pair of fixed vertical shapes, and which makes it possible to make the operation of each of said machines independent from the fact that provision is made for manual loading of the transfer machine in the event of the machine stopping. sew the spikes and the possibility of unloading the tights from the sewing machine in a storage and recovery store, in case the ironing machine stops.

Ce résultat a été atteint conformément à la présente invention en adoptant l'idée d'utiliser un procédé opératoire, en rappelant que ce qui se rapporte aux collant est également valable pour les bas et les chaussettes, lequel comporte, en succession, les opérations suivantes:

  • ― prise du collant par le bord élastique du corps, transport hors de la station de déchargement de la machine à coudre les pointes et retournement dudit bord élastique et du collant tout entier;
  • ― transfert du bord élastique du collant ainsi retourné, sur des moyens de prise qui se déplacent par intermittence vers la machine à repasser, élargissement en un rectangle vertical et orientation successive dans un plan horizontal du bord élastique ainsi élargi et dans une position prédéterminée en correspondance de la station de chargement de la machine à repasser;
  • ― prélèvement du bord élastique du collant ainsi élargi et orienté et transfert du collant avec mouvement du bas vers le haut de manière à ce que les jambes s'enfilent sur les deux formes verticales fixes de ladite machine à repasser.
This result was achieved in accordance with the present invention by adopting the idea of using an operating process, by recalling that what relates to tights is also valid for stockings and socks, which comprises, in succession, the following operations :
  • - grip of the pantyhose by the elastic edge of the body, transport out of the unloading station of the sewing machine, and turning of the elastic edge and the whole pantyhose;
  • - transfer of the elastic edge of the tights thus returned, onto gripping means which move intermittently towards the ironing machine, widening in a vertical rectangle and successive orientation in a horizontal plane of the elastic edge thus widened and in a predetermined position in correspondence the ironing machine loading station;
  • - removal of the elastic edge of the pantyhose thus widened and oriented and transfer of the pantyhose with movement from the bottom upwards so that the legs are threaded onto the two fixed vertical shapes of said ironing machine.

Selon une forme préférée de réalisation, une machine pour le transfert automatique des collants d'une machine qui coud les pointes à une machine qui repasse les collants suivant ledit procédé en conformité avec l'invention, comprend:

  • ― un bras pourvu de deux pinces, agissant en correspondance des deux extrémités latérales du bord élastique du corps du collant qui est enfilé sur une paire de tubes de la machine à coudre les pointes dans sa station de déchargement, lequel bras est fixé sur un chariot avec mouvement rectiligne alternatif pour permettre de prendre et de porter hors de la machine à coudre les pointes ledit bord élastique du collant présent, de retourner ainsi ledit bord élastique et de maintenir le collant complètement retourné et en position suspendue;
  • ― une table horizontale tournante par intermittence et pourvue de plusieurs stations opérationnelles, laquelle supporte un nombre identique de bras horizontaux avec éléments écartables verticalement, chacun desquels permet de prendre le bord élastique du collant maintenu tendu par ladite paire de pinces hors de la machine à coudre les pointes, de l'élargir ainsi en forme de rectangle dans un plan vertical alors que le collant est en position suspendue, de le faire tourner ensuite autour d'un axe horizontal et autour d'un axe vertical pour permettre de disposer le bord élastique du collant ainsi élargi dans une position horizontale et située dessous les deux formes verticales fixes de la machine à repasser dont les pointes sont orientées vers le bas, et de disposer simultanément les coutures du corps du collant dans un plan vertical et médian par rapport auxdites formes de la machine à repasser, de manière à prédisposer les jambes du collant pour l'enfilement sur lesdites formes;
  • ― deux bras pourvus de deux dents horizontales, parallèles et écartables horizontalement, associées à un chariot avec mouvement vertical alternatif, dans une position située derrière les formes de la machine à repasser et pendant la course vers le bas desquels, lesdites dents s'introduisent à l'intérieur du bord élastique du collant en le prélevant du bras correspondant de la table tournante précitée, et pendant la course vers le haut successive desquels, ils positionnent les corps du collant autour desdites formes en enfilant les jambes sur celles-ci; des moyens étant prévus pour décharger le collant desdites dents.
According to a preferred embodiment, a machine for the automatic transfer of the tights from a machine which sews the tips to a machine which iron the tights according to said method in accordance with the invention, comprises:
  • - an arm provided with two clips, acting in correspondence of the two lateral ends of the elastic edge of the body of the pantyhose which is threaded on a pair of tubes of the sewing machine spikes in its unloading station, which arm is fixed on a trolley with reciprocating rectilinear movement to allow taking and carrying out of the spikes the said elastic edge of the sticky present, thus turning over said elastic edge and maintaining the tights completely turned over and in the hanging position;
  • - a horizontal table rotating intermittently and provided with several operational stations, which supports an identical number of horizontal arms with vertically separable elements, each of which makes it possible to take the elastic edge of the tights kept stretched by said pair of pliers out of the sewing machine the tips, to widen it thus in the shape of a rectangle in a vertical plane while the tights are in the hanging position, to make it then rotate around a horizontal axis and around a vertical axis to allow to have the elastic edge pantyhose thus widened in a horizontal position and located below the two fixed vertical shapes of the ironing machine, the tips of which are oriented downwards, and simultaneously placing the seams of the pantyhose body in a vertical and median plane with respect to said shapes of the ironing machine, so as to predispose the legs of the pantyhose for threading on the say forms;
  • - two arms provided with two horizontal teeth, parallel and horizontally separable, associated with a carriage with reciprocating vertical movement, in a position located behind the shapes of the ironing machine and during the downward stroke of which, said teeth are introduced inside the elastic edge of the pantyhose by removing it from the corresponding arm of the aforementioned turntable, and during the successive upward stroke of which, they position the bodies of the pantyhose around said shapes by threading the legs thereon; means being provided for discharging the pantyhose from said teeth.

La solution proposée selon la présente invention permet le transfert des collants entre deux machines, l'une qui coud les pointes et l'autre qui repasse, tout en conservant l'indépendance de fonctionnement de chacune; et ceci grâce à la possibilité de déchargement automatique des collants de la machine à coudre les pointes sur un magasin de stockage et la possibilité de chargement manuel des collants sur une station intermédiaire de la présente machine, le tout avec un rythme de travail très élevé (environ 2,5 secondes par collant).The solution proposed according to the present invention allows the transfer of tights between two machines, one which sews the tips and the other which iron, while retaining the independence of operation of each; and this thanks to the possibility of automatic unloading of tights from the stitch sewing machine on a storage magazine and the possibility of manual loading of tights on an intermediate station of this machine, all with a very high work rate ( about 2.5 seconds per sticker).

Finally, in correspondence with the loading station of the ironing machine W, (reference to FIGS. 2 and 11-20), said machine for transferring the tights comprises:
  • A vertical structure 41 fixed, in position behind the forms 4 of the ironing machine W, with a track or rail 42 and a chain 43 closed in a ring on two wheels 44, the lower wheel taking the movement, with traditional means, of the same electric motor which turns said table 22 or of an independent electric motor;
  • - A carriage 45, sliding on said track 42, by means of said chain 43 and provided with two parallel arms 46 whose ends 46 ′ folded and juxtaposed, can be spread horizontally: for this purpose, said arms 46 are provided with toothing corresponding 47 in which engages a vertical toothed or grooved rod 48 corresponding passing through said carriage 45 and whose rotation, which is programmed in one direction or the other, determines in cooperation with a idler 49 disposed between said arms 46, the reconciliation or reciprocal distancing of their ends;
  • - A buffer type extractor 50, oscillating, placed laterally at at least one of the forms 4 of the ironing machine W, whose programmed intervention allows the unloading of the tights 5 from said arms 46; alternatively, the extractor can be of the fixed type with two stops 51 with two corresponding nozzles 52 blowing air on the adhesive 5 near said arms.

Le fonctionnement est le suivant. A peine la machine à coudre les pointes T transporte dans la station de déchargement un collant 5 terminé, c'est à dire avec les pointes cousues, les deux pinces 13 de la première section prennent le bord élastique 5′ du collant 5 qui est tendu autour des tubes de retournement 1 de la machine à coudre les pointes T dans les points présentant l'interdistance horizontale maximale, le chariot se déplace ainsi vers et au-delà de l'extrémité desdits tubes 1 et, pendant que l'aspiration des jambes 5˝ du collant à l'intérieur des tubes en provoque le retournement, c'est à dire de l'envers à l'endroit, lesdites pinces 13, en tournant sur elles-même de 180° vers l'extérieur du collant, effectuent le retournement de son bord élastique 5′. Lorsque ledit chariot 12 arrive en fin de course de sortie de la machine à coudre les points T, les deux paires de becs horizontaux 31 du bras 29 de la table 22 qui est arrêtée dans la première station S1, se trouvent à l'intérieur du bord élastique du collant tenu par lesdites pinces, alors que le reste du collant est en position suspendue; après quoi, alors que le chariot 12 revient en arrière vers le centre de la machine à coudre les pointes T, la table 22, tournant dans le sens horaire, transporte le bras 29 avec le collant dans la deuxième station S2 et après une pause, dans la troisième station S3; entre la troisième station S3 et la cinquième station S5 de la table 22, le bras 29 effectue une rotation sur lui-même de 90° vers le bas et vers l'extérieur de la table et le support 23 effectue une rotation sur lui-même d'environ 120° dans le sens contraire à celui des aiguilles d'une montre de telle manière que dans la cinquième station S5 de la table, le bord tendu en rectangle du collant soit horizontal et disposé au-dessous des pointes des formes 4 de la machine à repasser W et avec l'ouverture orientée vers le haut, alors que les coutures du corps du collant, qui est suspendu, se trouvent dans le plan vertical médian par rapport auxdites formes 4.The operation is as follows. No sooner does the T-point sewing machine transport finished tights 5 to the unloading station, that is to say with the sewn stitches, the two clips 13 of the first section take the elastic edge 5 ′ of the tights 5 which is stretched around the turning tubes 1 of the sewing machine the stitches T in the stitches presenting the maximum horizontal prohibition, the carriage thus moves towards and beyond the end of said tubes 1 and, while the suction of the legs 5˝ of the pantyhose inside the tubes causes it to turn over, that is to say upside down, said clamps 13, by turning 180 ° towards themselves outside the pantyhose, effect the reversal of its elastic edge 5 ′. When said carriage 12 reaches the end of the output stitching machine T travel, the two pairs of horizontal spouts 31 of the arm 29 of the table 22 which is stopped in the first station S1, are located inside the elastic edge of the pantyhose held by said clips, while the rest of the pantyhose is in the suspended position; after which, while the carriage 12 goes back towards the center of the stitch sewing machine T, the table 22, turning clockwise, transports the arm 29 with the tights into the second station S2 and after a pause, in the third station S3; between the third station S3 and the fifth station S5 of the table 22, the arm 29 rotates on itself 90 ° downwards and outwards of the table and the support 23 rotates on itself approximately 120 ° counterclockwise so that in the fifth station S5 of the table, the rectangle stretched edge of the pantyhose is horizontal and disposed below the tips of the shapes of the ironing machine W and with the opening facing upwards, while the seams of the body of the pantyhose, which is suspended, lie in the median vertical plane with respect to said forms 4.

A ce point, le chariot 45 lequel se trouve plus haut que le bord tendu du collant, et plus bas que les pointes des formes 4 de la machine à repasser W, descend et à peine les extrémités 46′ se trouvent à l'intérieur du bord élastique 5′ du collant 5, celles-ci sont écartées en tendant en conséquence le bord élastique du collant, lequel, alors que le chariot poursuit sa course descendante, est désenfilé des becs 31 dudit bras 29; successivement, le chariot 45 remonte jusqu' à ce que les jambes 5˝ du collant 5 soient enfilées sur les formes 4; la fin de course montante du collant, avec l'abandon des extrémités 46′, est déterminée par l'activation de l'extracteur si il est du type à tampon 50 ou autrement par la butée du bord élastique 5′ du collant contre les extracteurs fixes 51 disposés au-dessus.At this point, the carriage 45 which is higher than the taut edge of the pantyhose, and lower than the tips of the forms 4 of the ironing machine W, descends and hardly the ends 46 ′ are inside the elastic edge 5 ′ of the pantyhose 5, these are separated by stretching accordingly the elastic edge of the pantyhose, which, while the carriage continues its downward travel, is removed from the nozzles 31 of said arm 29; successively, the carriage 45 rises until the legs 5˝ of the pantyhose 5 are threaded onto the forms 4; the rising end of the pantyhose, with the abandonment of the ends 46 ′, is determined by the activation of the extractor if it is of the tampon type 50 or otherwise by the stop of the elastic edge 5 ′ of the pantyhose against the extractors fixed 51 arranged above.

Entre la cinquième et la première station de la table 22, le bras 29 subit une rotation sur lui-même de 90° vers le haut et le support subit une rotation autour de son axe d'environ 120° dans le sens horaire pour permettre que, une fois le support 23 ramené dans ladite première station S1 de la table 22, le bras 29 avec les becs 31 correspondants se trouve dans la même position de départ.Between the fifth and the first station of the table 22, the arm 29 is rotated about itself 90 ° upwards and the support is rotated about its axis by about 120 ° clockwise to allow that , once the support 23 returned to said first station S1 of the table 22, the arm 29 with the spouts 31 correspondents is in the same starting position.

Il est évident qu' avec la machine en fonctionnement nominal, à chaque arrêt de la table 22 un collant est transféré de la machine à coudre les pointes T sur un bras 29 correspondant de la table 22 pendant que, simultanément, un autre collant est transféré d'un autre bras 29 de la table sur les extrémités 46′ des bras 46 du chariot 45 qui se trouve en correspondance de la machine à repasser.It is obvious that with the machine in nominal operation, at each stop of the table 22, a pantyhose is transferred from the sewing machine T-tips to a corresponding arm 29 of the table 22 while, simultaneously, another pantyhose is transferred. another arm 29 of the table on the ends 46 ′ of the arms 46 of the carriage 45 which is located in correspondence with the ironing machine.

En cas d'arrêt de la machine à coudre les pointes T, les bras 29 de la table 22 peuvent être chargés à la main dans la deuxième station S2 de la table, alors que dans le cas d'un arrêt de la machine à repasser W, les collants peuvent être déchargés de la machine à coudre les pointes T sur un magasin 3 situé au-dessous.In case of stopping of the T-point sewing machine, the arms 29 of the table 22 can be loaded by hand in the second station S2 of the table, while in the case of a stopping of the ironing machine W, the tights can be unloaded from the T-point sewing machine at a magazine 3 located below.

Enfin, en tenant compte du fait qu'aussi bien la machine qui coud les pointes T que celle qui les repasse peuvent également travailler sur des bas ou des chaussettes, la machine qui fait l'objet de la présente invention se prête également au transfert de ces produits manufacturés de la première à la deuxième machine.Finally, taking into account the fact that both the machine which sews the T tops and the one which passes them can also work on stockings or socks, the machine which is the subject of the present invention also lends itself to the transfer of these manufactured products from the first to the second machine.
