Abstract

To invert a sock, produced on a circular knitter, the sock is carried by suction from the knitter to a displaced inversion station, where it is stopped and held with the elastic welt upwards. The elastic welt is gripped equidistantly round its circumference, and is opened out by centrifugal force. While the welt is held open, it is pulled towards the toe to invert the sock. The welt is released and the sock is carried onwards by suction, with the toe leading.

Description

La présente invention concerne un procédé et un dispositif pour retourner les chaussettes hors et à distance de la machine de traitement correspondante.The present invention relates to a method and a device for turning the socks off and at a distance from the corresponding processing machine.

Il est connu qu'au terme de la production avec une machine à tricoter circulaire, les chaussettes pour homme, appelées par la suite "chaussettes", doivent être retournées pour permettre d'autres opérations de finition, comme par exemple la couture invisible de la pointe.
Il est également connu qu'après ladite couture de la pointe, les chaussettes doivent être de nouveau retournées afin de les remettre à l'endroit.
Actuellement, l'opération de retournement est effectuée au moyen d'un dispositif retourneur, uniquement sur les machines à tricoter circulaire pour la bonneterie, sur lesquelles il est fixé coaxialement avec le cylindre des aiguilles et en effectuant le retournement par voie pneumatique.
Mais ce dispositif connu présente certains inconvénients importants. Un premier inconvénient consiste en ce qu'il est monté à l'intérieur de la machine circulaire de sorte qu'il nécessite une adaptation différente en fonction du type de machine auquel il est destiné. Un autre inconvénient dépend du fonctionnement pneumatique qui présente une fiabilité limitée due en partie à la rigidité propre des chaussettes et en partie aux impuretés aspirées inévitablement par la machine qui imposent son arrêt avec une certaine fréquence en diminuant ainsi sa capacité de production.
It is known that at the end of production with a circular knitting machine, men's socks, hereinafter called "socks", must be turned over to allow other finishing operations, such as invisible stitching of the point.
It is also known that after said stitching of the tip, the socks must be turned over again in order to put them back on the right side.
Currently, the turning operation is carried out by means of a turning device, only on circular knitting machines for hosiery, on which it is fixed coaxially with the needle cylinder and by turning it pneumatically.
However, this known device has certain significant drawbacks. A first drawback is that it is mounted inside the circular machine so that it requires a different adaptation depending on the type of machine for which it is intended. Another drawback depends on the pneumatic operation which has limited reliability due in part to the inherent rigidity of the socks and in part to the impurities inevitably sucked in by the machine which impose its stopping with a certain frequency thereby reducing its production capacity.

Pour ce qui concerne le retournement après la couture de la pointe, les chaussettes sont encore retournées à la main.Regarding the turning after sewing the point, the socks are still turned by hand.

La présente invention a pour but d'éliminer les inconvénients précités.
Ce résultat a été atteint conformément à l'invention en adoptant un procédé de traitement qui comprend, successivement, les phases suivantes:
- aspirer la chaussette à partir de la machine de traitement correspondante et la transporter hors et à distance de celle-ci, orientée avec la bande élastique en avant;
- arrêter la chaussette ainsi transportée, en position verticale et avec la bande élastique tournée vers le haut;
- saisir de l'extérieur et en plusieurs points la bande élastique de la chaussette ainsi positionnée, et appliquer au niveau desdits points une traction en direction horizontale centrifuge de manière à ouvrir la bande en rond;
- serrer de l'extérieur la bande élastique ainsi ouverte en rond;
- retourner la chaussette sur elle-même en la faisant passer à travers la bande élastique ainsi ouverte et serrée, en procédant de la bande élastique vers et jusqu'à la pointe du pied;
- libérer la bande élastique de la chaussette ainsi retournée et décharger la chaussette orientée avec la pointe du pied en avant.
Et pour mettre en oeuvre ledit procédé, il est prévu d'utiliser:
- des moyens pour extraire la chaussette de la machine de traitement correspondante en l'aspirant dans un conduit qui la transporte jusqu'à une station de retournement placée à distance de la machine et, après le retournement, pour l'envoyer au dispositif de déchargement;
- une station de retournement comprenant: une chambre à axe vertical, avec une cloison interne grillagée, articulée pour intercepter et positionner la chaussette en position verticale et avec la bande élastique en haut; des moyens pour saisir la bande élastique de l'extérieur, lesquels sont soumis à une traction centrifuge pour en effectuer l'ouverture en rond; des moyens externes à la chaussette et soumis à une poussée verticale vers le haut pour serrer toute la bande élastique contre le siège de ladite cloison; un tube de retournement coaxial avec ladite chambre, passant dans ladite tasse et dans l'ouverture de ladite cloison et dans lequel est logée la chaussette, lequel est soumis à un mouvement vertical alternatif dont la course vers le haut, avec la cloison ouverte, provoque le retournement de la chaussette sur elle-même, de la bande élastique jusqu'à la pointe du pied, et son passage simultané à travers l'ouverture de la cloison;
- une cloche d'expulsion de la chaussette retournée et avec la pointe en avant.
The present invention aims to eliminate the aforementioned drawbacks.
This result was achieved in accordance with the invention by adopting a treatment method which successively comprises the following phases:
- vacuum the sock from the corresponding treatment machine and transport it out of and away from it, oriented with the elastic band in front;
- stop the sock thus transported, in a vertical position and with the elastic band facing upwards;
- grasp from the outside and at several points the elastic band of the sock thus positioned, and apply at said points a traction in horizontal centrifugal direction so as to open the band in the round;
- tighten the elastic band thus opened in the round from the outside;
- turn the sock over itself by passing it through the elastic band thus open and tight, proceeding from the elastic band to and up to the point of the toe;
- release the elastic band from the sock thus turned over and unload the oriented sock with your toes forward.
And to implement said method, it is planned to use:
- Means for extracting the sock from the corresponding treatment machine by sucking it up in a duct which transports it to a turning station located at a distance from the machine and, after turning, to send it to the unloading device ;
- a turning station comprising: a chamber with a vertical axis, with an internal mesh partition, articulated to intercept and position the sock in a vertical position and with the elastic band at the top; means for gripping the elastic band from the outside, which are subjected to centrifugal traction to open it in the round; means external to the sock and subjected to a vertical upward thrust to clamp the entire elastic band against the seat of said partition; a turning tube coaxial with said chamber, passing through said cup and into the opening of said partition and in which the sock is housed, which is subjected to an alternating vertical movement whose upward stroke, with the partition open, causes the reversal of the sock on itself, from the elastic band to the tip of the foot, and its simultaneous passage through the opening of the partition;
- an expulsion bell of the sock turned upside down and with the point forward.

Avantageusement, lesdits moyens pour saisir la bande élastique de la chaussette sont constitués par plusieurs pinces coplanaires, réparties autour de ladite chambre, angulairement équidistantes et mobiles horizontalement dans la direction radiale avec commande pneumatique.Advantageously, said means for gripping the elastic band of the sock consist of several coplanar clips, distributed around said chamber, angularly equidistant and movable horizontally in the radial direction with pneumatic control.

Lesdits moyens pour assurer le blocage de la bande élastique de la chaussette en position ouverte en rond sont avantageusement constitués par une tasse, enfilée coulissante sur le tube de retournement et sollicitée élastiquement contre la tête de celui-­ci.Said means for ensuring the blocking of the elastic band of the sock in the open position in the round are advantageously constituted by a cup, slidably threaded on the turn-up tube and urged elastically against the head thereof.

Les avantages obtenus grâce à la présente invention consistent essentiellement dans le fait que le retournement de la chaussette est effectué à l'extérieur et à distance de la machine de traitement correspondante, aussi bien une machine à tricoter circulaire pour bonneterie qu'une machine à coudre les pointes, et, par conséquent, sans interférer sur son fonctionnement; que le retournement proprement dit est obtenu complètement par voie mécanique en agissant axialement sur toute la circonférence de la chaussette et progressivement sur chaque rang de mailles correspondant; qu'il est possible d'obtenir le retournement correct et fiable et, en outre, en un temps inférieur à celui nécessaire pour la production de la chaussette de la part d'une machine circulaire, de sorte que plusieurs machines circulaires peuvent être servies par un seul dispositif de retournement.The advantages obtained thanks to the present invention essentially consist in the fact that the turning of the sock is carried out outside and at a distance from the corresponding processing machine, both a circular knitting machine for hosiery and a sewing machine. the spikes, and therefore without interfering with its operation; that the upturn itself is obtained completely mechanically by acting axially on the entire circumference of the sock and gradually on each row of stitches corresponding; that it is possible to obtain the correct and reliable turnaround and, moreover, in a time less than that necessary for the production of the sock on the part of a circular machine, so that several circular machines can be served by a single turning device.

Selon une forme de réalisation préférée, un dispositif pour retourner les chaussettes hors de la machine de traitement correspondante suivant ledit procédé, conformément à l'invention et en référence aux Fig. 1 et 2 des dessins annexés, comprend:
- un conduit 2, relié rigidement à la sortie de la machine 1, pour recueillir la chaussette 3 après qu'elle ait été détachée de celle-ci, et pour sont transport pneumatique, avec l'interposition d'un tube mobile 5, jusqu'à une station de retournement 4 qui est reliée, en aval, à un conduit 8 d'aspiration pneumatique avec l'interposition d'un raccord 6 et d'une cloche d'expulsion 7;
- une station de retournement 4 avec une chambre cylindrique 40 à axe vertical, reliée par le haut audit raccord 6 et par le bas à un cylindre opérateur 9.
A l'intérieur de ladite chambre 40 se trouve une cloison grillagée 41, articulée sur son siège 42 avec ouverture circulaire 43 et pourvue d'un ressort de rappel dans la position horizontale, c'est-à-dire avec l'ouverture 43 fermée; ladite cloison étant destinée à intercepter la chaussette 3, aspirée dans la chambre 4, en l'arrêtant dans la position verticale avec la bande élastique 30 en haut.
A l'extérieur de ladite chambre 4 et à une hauteur à peine inférieure à celle de ladite cloison 41, plusieurs (par exemple quatre ou six) pinces 44 sont prévues, coulissantes dansd des sièges horizontaux 45 correspondants, disposés radialement et angulairement équidistants autour de la chambre et communicant avec celle-ci pour permettre, en fin de course centripète et respectivement centrifuge des pinces, de saisir et respectivement d'ouvrir en rond la bande élastique de la chaussette qui se trouve dans la chambre 4.
Conformément à l'invention, chacune desdites pinces 44 est montée sur le corps mobile 45 d'un cylindre pneumatique 46 à double effet et est asservie à un elément écarteur 47 qui est monté sur ledit corps 45 à l'arrière de la pince 44 et dont le déplacement en avant, à commande pneumatique, en provoque la fermeture, alors qu'un ressort à anneau 48 - avec l'écarteur 47 escamoté - en provoque l'ouverture.
Le fond de ladite chambre 4 est pourvu d'une ouverture circulaire axiale pour permettre le passage du tube 5 précité qui constitue le corps mobile d'un cylindre pneumatique 9 aligné avec la chambre 40 et à double effet, de manière à pouvoir prendre deux positions, l'une abaissée, dans laquelle le pied 50 s'engage sur la sortie du conduit 2 et la tête 51 se trouve dans la chambre 40 à une hauteur inférieure à celle des pinces 44 (voir Fig. 1) et l'autre élevée, dans laquelle la tête 51 du tube 5 passe à travers l'ouverture 43 de la cloison 41 jusqu'à atteindre le raccord 6 (voir Fig. 7).
Ledit tube 5 a pour fonction de retourner la chaussette 3 qui se trouve dans la chambre 40; en effet, dans la position abaissée du tube 5, la chaussette 3 se trouve en partie logée pendante à l'intérieur du tube et, après que la bande élastique 30 a été ouverte en rond par les pinces 44 et correctement maintenue ainsi, la tête 51 du tube 5, en se soulevant, est en mesure de retourner progressivement la chaussette vers le haut en la faisant passer à travers la bande élastique 30 ouverte.
Dans le but de bloquer la bande élastique 30 pendant le retournement de la chaussette 3, il est prévu, conformément à l'invention, de monter sur l'extrémité supérieure du tube 5 un élément annulaire en forme de tasse 52 qui est retenue au niveau de sa base par l'extrémité a bride 51 du tube 5 et qui est poussée vers le haut par un ressort à hélice cylindrique 53 situé au-dessous et enfilé sur le tube 5 lui-même.
Conformément à l'invention, il est prévu que le conduit 2 puisse amener séparément à la chambre 40 les chaussettes 3 produites par plusieurs machine à tricoter circulaire 1.
According to a preferred embodiment, a device for turning the socks out of the corresponding treatment machine according to said method, in accordance with the invention and with reference to FIGS. 1 and 2 of the accompanying drawings, includes:
- A conduit 2, rigidly connected to the outlet of the machine 1, to collect the sock 3 after it has been detached from it, and for are pneumatic transport, with the interposition of a movable tube 5, to a turning station 4 which is connected, downstream, to a pneumatic suction duct 8 with the interposition of a connector 6 and a expulsion bell 7;
a turning station 4 with a cylindrical chamber 40 with a vertical axis, connected from above to said connector 6 and from below to an operating cylinder 9.
Inside said chamber 40 is a mesh partition 41, articulated on its seat 42 with circular opening 43 and provided with a return spring in the horizontal position, that is to say with the opening 43 closed. ; said partition being intended to intercept the sock 3, sucked into the chamber 4, stopping it in the vertical position with the elastic band 30 at the top.
Outside said chamber 4 and at a height barely lower than that of said partition 41, several (for example four or six) clips 44 are provided, sliding in corresponding horizontal seats 45, arranged radially and angularly equidistant around the chamber and communicating with it to allow, at the end of the centripetal and respectively centrifugal travel of the clamps, to grasp and respectively to open in round the elastic band of the sock which is in the chamber 4.
According to the invention, each of said clamps 44 is mounted on the movable body 45 of a double-acting pneumatic cylinder 46 and is slaved to a spacer element 47 which is mounted on said body 45 at the rear of the clamp 44 and whose displacement forwards, pneumatically controlled, causes its closure, while a ring spring 48 - with the retractor 47 retracted - causes it to open.
The bottom of said chamber 4 is provided with an axial circular opening to allow the passage of the aforementioned tube 5 which constitutes the movable body of a pneumatic cylinder 9 aligned with the chamber 40 and with double effect, so as to be able to take two positions , one lowered, in which the foot 50 engages the outlet of the conduit 2 and the head 51 is located in the chamber 40 at a height less than that of the clamps 44 (see Fig. 1) and the other raised , in which the head 51 of the tube 5 passes through the opening 43 of the partition 41 until it reaches the connector 6 (see Fig. 7).
Said tube 5 has the function of turning over the sock 3 which is in the chamber 40; in fact, in the lowered position of the tube 5, the sock 3 is partially housed hanging inside the tube and, after the elastic band 30 has been opened in the round by the clamps 44 and correctly held thus, the head 51 of the tube 5, by lifting, is able to gradually turn the sock upwards by passing it through the elastic band 30 open.
In order to block the elastic band 30 during the turning of the sock 3, it is provided, in accordance with the invention, for mounting on the upper end of the tube 5 an annular cup-shaped element 52 which is retained at its base by the flanged end 51 of the tube 5 and which is pushed towards the top by a cylindrical helical spring 53 located below and threaded on the tube 5 itself.
According to the invention, provision is made for the conduit 2 to be able to bring the socks 3 produced by several circular knitting machines 1 separately to the chamber 40.

Le fonctionnement est le suivant. La chaussette 3, une fois terminée et détachée de la machine circulaire 1, est aspirée dans le conduit 2 et transportée jusqu'à l'intérieur de la chambre 40 où la cloison 41, qui est abaissée, l'arrête en position verticale et avec la bande élastique 30 en haut (voir Fig. 3); après quoi, les pinces 44, de préférences fermées, sont poussées à fond dans la chambre 40 et ensuite ouvertes de manière à recevoir la bande élastique 30 en autant de points (voir Fig. 4); ensuite les pinces 44 sont refermées et escamotées de manière à élargir, c'est-à-dire à ouvrir en rond, la bande 30 (voir Fig. 5). A ce stade, en actionnant le cylindre 9 par l'intermédiaire de l'entrée 91, le tube de retournement 5 se soulève et, après le blocage de la bande 30 contre le siège 42 de la cloison 41 par la tasse 52 sous l'effet de la poussée du ressort 53, l'extrémité à bride 51 du tube 5, en poursuivant sa course vers le haut, soulève la cloison 41 et entra ne vers le haut la chaussette 3 en la retournant (voir Fig. 6). Une fois le retournement terminé, en actionnant le cylindre 9 au moyen de l'entrée 92, le tube 5 revient en arrière et, durant sa course de descente, rabaisse la tasse 52 (voir Fig. 7); enfin, en ouvrant le pinces 44, la chaussette retournée 3′ est libérée et aspirée dans la cloche 7 d'expulsion, et la cloison 41 redescend immédiatement en refermant l'ouverture 43 (voir Fig. 8).The operation is as follows. The sock 3, once finished and detached from the circular machine 1, is sucked into the conduit 2 and transported to the interior of the chamber 40 where the partition 41, which is lowered, stops it in the vertical position and with the elastic band 30 at the top (see FIG. 3); after which, the clamps 44, preferably closed, are pushed fully into the chamber 40 and then open so as to receive the elastic band 30 at as many points (see FIG. 4); then the clamps 44 are closed and retracted so as to widen, that is to say open in the round, the strip 30 (see FIG. 5). At this stage, by actuating the cylinder 9 via the inlet 91, the turning tube 5 is raised and, after the blocking of the strip 30 against the seat 42 of the partition 41 by the cup 52 under the effect of the thrust of the spring 53, the flanged end 51 of the tube 5, while continuing its upward movement, raises the partition 41 and entered sock 3 upwards by turning it over (see Fig. 6). Once the inversion is complete, by actuating the cylinder 9 by means of the inlet 92, the tube 5 returns back and, during its downward stroke, lowers the cup 52 (see Fig. 7); finally, by opening the clips 44, the inverted sock 3 ′ is released and sucked into the expulsion bell 7, and the partition 41 immediately descends by closing the opening 43 (see Fig. 8).
