Description

L'invention concerne une machine à séparer des chapelets d'articles textiles tubulaires assemblés par des fils fragiles et à retourner éventuellement au préalable lesdits chapelets.The invention relates to a machine for separating strings of tubular textile articles assembled by fragile threads and optionally turning said strings beforehand.

Il est connu d'utiliser des machines à tricoter et plus particulièrement des machines dites "à double cylindre " destinées à tricoter des articles sous forme de chapelets continus dans lesquels les articles sont reliés les uns aux autres par un fil de séparation. Les procédés de séparation desdits articles à l'unité dépendent du fil de séparation utilisé.It is known to use knitting machines and more particularly so-called "double cylinder" machines intended for knitting articles in the form of continuous strings in which the articles are connected to each other by a separation thread. The methods of separating said items individually depend on the separation wire used.

Il existe en effet des fils de séparation en matière textile classique qui sont extraits du tricot par démaillage.There are, in fact, separation threads made of conventional textile material which are extracted from knitting by unraveling.

D'autres fils de séparation sont solubles et sont retirés par dissolution. L'inconvénient de ces fils est du à la nécessité de mouiller et de sécher les articles.Other separation wires are soluble and are removed by dissolution. The disadvantage of these threads is due to the need to wet and dry the articles.

Une autre technique consiste à utiliser des fils fusibles qui sont détruits par un traitement thermique. Cette technique entraine cependant des risques de détérioration de l'article lui-même et ne procure généralement qu'une élimination partielle.Another technique consists in using fusible wires which are destroyed by a heat treatment. This technique however entails risks of deterioration of the article itself and generally only provides a partial elimination.

Enfin, il existe aussi des fils de séparation fragiles et éventuellement aussi fusibles ou solubles qui cèdent par une traction manuelle ou mécanique. La résistance de tels fils est, bien entendu, inférieure à celle des fils de l' article.Finally, there are also fragile and possibly also fusible or soluble separation wires which yield by manual or mechanical traction. The resistance of such wires is, of course, lower than that of the wires of the article.

Cette technique de tricotage en chapelets peut concerner divers articles textiles tels que des manches de pull-over par exemple, mais concerne plus particulièrement la fabrication de chaussettes. Les chapelets de chaussettes sont généralement retournés soit avant, soit après la séparation des articles tandis que l'opération suivante consiste à fermer les pointes sur une machine à coudre ou à remailler. "This technique of knitting in strings can relate to various textile articles such as sweater sleeves. for example, but more particularly relates to the manufacture of socks. The strings of socks are generally turned over either before or after the separation of the articles while the next operation consists in closing the points on a sewing or re-stitching machine. "

L'invention propose une machine à séparer par rupture des chapelets d'articles textiles tubulaires,tels que des chapelets de chaussettes,assemblés par des fils fragiles.Ces derniers peuvent aussi être ,dans certains cas, solubles ou fusibles, de manière à pouvoir éliminer les résidus qui peuvent rester sur les articles, après la rupture desdits fils.The invention provides a machine for breaking apart strings of tubular textile articles, such as strings of socks, assembled by fragile threads. These strands may also, in certain cases, be soluble or fusible, so as to be able to eliminate residues which may remain on the articles, after the breakage of said wires.

La machine selon l'invention est remarquable en ce qu' elle comporte :

  • - un tube de transport du chapelet,
  • - un aspirateur aménagé de manière à créer dans le tube une dépression destinée à attirer ledit chapelet,
  • - un moyen de surpression aménagé de manière à ouvrir un clapet mobile d'obturation qui autrement ferme le tube au delà de l'aspirateur et à entrainer l'extrémité antérieure du chapelet alors que l'extrémité postérieure est encore aspirée par l'aspirateur,
  • - et un séparateur du chapelet par unités d'articles disposé à l'extrémité du tube sous le clapet tandis que des moyens électriques sont prévus pour actionner le moyen de surpression au cours du trajet du chapelet et arrêter celui-ci lorsque ledit chapelet a atteint le séparateur.
The machine according to the invention is remarkable in that it comprises:
  • - a rosary transport tube,
  • a vacuum cleaner arranged so as to create a depression in the tube intended to attract said string,
  • a means of overpressure arranged so as to open a movable shutter valve which otherwise closes the tube beyond the vacuum cleaner and to drive the front end of the chain while the rear end is still sucked by the vacuum cleaner,
  • - And a separator of the rosary by units of articles placed at the end of the tube under the valve while electrical means are provided to actuate the means of overpressure during the path of the rosary and stop it when said rosary has reached the separator.

Dans le cas où il est nécessaire de retourner le chapelet, lorsqu'il s'agit par exemple de chapelets de chaussettes, la machine est remarquable en ce que le tube de transport est aménagé de manière connue pour recevoir un chapelet par enfilage, au moyen éventuellement d'un rouleau d'entrai- nement, de manière telle que ledit chapelet peut être retourné dans le tube puis attiré par l'aspiration engendrée par l'aspirateur.In the case where it is necessary to turn the rosary, when it is for example strings of socks, the machine is remarkable in that the transport tube is arranged in a known manner to receive a rosary by threading, by means possibly with a drive roller, so that said chain can be turned over in the tube and then attracted by the suction generated by the vacuum cleaner.

Avantageusement l'aspirateur est formé par un moyen d' aspiration qui communique avec une chambre aménagée autour du tube qui présente à cet endroit une paroi ajourée à la manière d'une crépine de telle sorte que le chapelet est appliqué par aspiration contre la paroi interne ajourée dudit tube.Advantageously, the vacuum cleaner is formed by a suction means which communicates with a chamber arranged around the tube which has an openwork wall at this location in the manner of a strainer so that the rosary is applied by suction against the perforated internal wall of said tube.

De préférence, le moyen de surpression est formé par une alimentation en air comprimé, commandée par exemple par une électro-vanne et reliée au tube par un raccord oblique incliné vers le clapet qui s'ouvre sous l'action de l'air comprimé lorsque ladite alimentation est ouverte.Preferably, the overpressure means is formed by a compressed air supply, controlled for example by a solenoid valve and connected to the tube by an oblique connection inclined towards the valve which opens under the action of compressed air when said supply is open.

Le séparateur peut être formé par deux paires successives de rouleaux rotatifs, la vitesse linéaire de rotation de la deuxième paire étant supérieure à celle de la première de manière telle que le chapelet est entrainé entre les rouleaux de chaque paire et que la différence de vitesse permet aux rouleaux de la deuxième paire d'exercer une traction suffisante pour casser les fils d'assemblage des articles du chapelet.The separator can be formed by two successive pairs of rotating rollers, the linear speed of rotation of the second pair being greater than that of the first so that the chain is driven between the rollers of each pair and the difference in speed allows to the rollers of the second pair to exert sufficient traction to break the assembly threads of the articles of the rosary.

Selon un mode de réalisation préféré,le moyen électrique prévu pour actionner le moyen de surpression au cours du trajet du chapelet comporte un palpeur, disposé dans le tube de transport avant l'aspirateur et qui commande électriquement le moyen de surpression tandis que le moyen d'arrêt de ce dernier est formé par un contact électrique commandé par le séparateur lorsque celui-ci reçoit le chapelet.According to a preferred embodiment, the electrical means provided for actuating the overpressure means during the path of the rosary comprises a feeler, disposed in the transport tube before the vacuum cleaner and which electrically controls the overpressure means while the means d 'stop of the latter is formed by an electrical contact controlled by the separator when the latter receives the chain.

Dans ce cas avantageusement le palpeur commande le moyen de surpression par l'intermédiaire d'un relais bi-stable ou auto-alimenté sur lequel agit également le contact électrique d'arrêt. Lorsque le moyen de surpression comporte une alimentation en air comprimé commandée par une électro-vanne, le relais bi-stable agit directement sur celle-ci.In this case, the probe advantageously controls the overpressure means by means of a bi-stable or self-powered relay on which the electrical stop contact also acts. When the overpressure means comprises a compressed air supply controlled by a solenoid valve, the bi-stable relay acts directly on it.

L'invention sera mieux comprise à la lecture de la description qui va suivre d'un mode de réalisation de l'invention donné à titre d'exemple et qui se réfère au dessin unique annexé.The invention will be better understood on reading the description which follows of an embodiment of the invention given by way of example and which refers to the single appended drawing.

Le dessin montre schématiquement un mode de réalisation selon l'invention qui présente un tube de transport 1 sur lequel est enfilé un chapelet 2,de chaussettes par exemple, au moyen du rouleau d'entrainement 3.The drawing schematically shows an embodiment according to the invention which presents a transport tube 1 on which is strung a chain 2, of socks for example, by means of the drive roller 3.

Un moyen d'aspiration 4 communique avec une chambre 5 aménagée autour du tube 1 qui présente à cet endroit une paroi la, ajourée à la manière d'une crépine.A suction means 4 communicates with a chamber 5 arranged around the tube 1 which has at this location a wall la, perforated in the manner of a strainer.

L'extrémité inférieure du tube 1 est munie d'une valve 6 comportant un clapet mobile d'obturation 7.The lower end of the tube 1 is provided with a valve 6 comprising a movable shutter valve 7.

Une alimentation 8 en air comprimé commandée par une électro-vanne 9 est reliée au tube 1 par un raccord oblique 10 incliné vers le clapet 7.A compressed air supply 8 controlled by a solenoid valve 9 is connected to the tube 1 by an oblique connection 10 inclined towards the valve 7.

En dessous de la valve 6 est aménagé un séparateur 11 comportant deux paires superposées de rouleaux rotatifs 12 et 13. Les rouleaux tournent dans le sens indiqué par les flèches à des vitesses linéaires différentes d'une paire à l'autre, les rouleaux 13 ayant une vitesse légèrement supérieure à celle des rouleaux 12.Below the valve 6 is arranged a separator 11 comprising two superposed pairs of rotary rollers 12 and 1 3. The rollers rotate in the direction indicated by the arrows at different linear speeds from one pair to the other, the rollers 13 having a speed slightly higher than that of the rollers 12.

Un palpeur électrique 14 est disposé dans le tube 1 au dessus de la chambre 5. Ce palpeur agit par l'intermédiaire d'un relais bi-stable ou auto-alimenté, non représenté, sur l'électro-vanne 9. Au moins un rouleau de chaque paire peut s'écarter de son rouleau antagoniste tandis qu'il est sollicité vers celui-ci par un moyen élastique tel qu'un ressort 15, qui agit sur un bras support 16 dudit rouleau. Un contact électrique 17 est en outre aménagé pour être commandé par le déplacement du bras 16 de la paire supérieure de rouleaux 12 lorsque ces derniers s'écartent l'un de l'autre. Ce contact 17 agit sur l'électro-vanne 9 par exemple par l' intermédiaire du relais sus-mentionné.An electric probe 14 is placed in the tube 1 above the chamber 5. This probe acts via a bi-stable or self-powered relay, not shown, on the solenoid valve 9. At least one roller of each pair can deviate from its opposing roller while it is biased towards it by an elastic means such as a spring 15, which acts on a support arm 16 of said roller. An electrical contact 17 is further arranged to be controlled by the movement of the arm 16 of the upper pair of rollers 12 when the latter move away from one another. This contact 17 acts on the solenoid valve 9 for example by means of the above-mentioned relay.

Le fonctionnement est simple à comprendre. Le moyen d'aspiration 4 crée dans le tube 1, par l'intermédiaire de la chambre 5, une dépression qui entraine la fermeture du clapet 7 et l'aspiration du chapelet 2 dont l'extrémité est introduire, après retournement (voir la flèche F), dans l' orifice d'extrémité du tube 1. Le chapelet 2 est ainsi aspiré jusqu'au niveau de la chambre 5.The operation is simple to understand. The suction means 4 creates in the tube 1, through the chamber 5, a depression which causes the closure of the valve 7 and the suction of the chain 2, the end of which is introduced, after turning (see the arrow F), in the end orifice of the tube 1. The chain 2 is thus sucked up to the level of the chamber 5.

Avant d'atteindre ladite chambre 5, le chapelet actionne le palpeur 14 qui commande par l'intermédiaire du relais précité l'ouverture de l'électro-vanne 9 de l'alimentation en air comprimé 8. L'air'comprimé ainsi libéré arrive dans le tube 1 par le raccord 10 et engendre une surpression qui, d'une part, entraine l'ouverture du clapet 7 de la valve 6 et, d'autre part, crée, en amont, une dépression supplémentaire dans le tube 1, de telle sorte que le chapelet 2 est aspiré vers le raccord 10 et poussé à travers la valve 7 entre la paire de rouleaux 12.Before reaching said chamber 5, the chain activates the probe 14 which controls, via the aforementioned relay, the opening of the solenoid valve 9 of the compressed air supply 8. The compressed air thus released arrives in the tube 1 by the connector 10 and generates an overpressure which, on the one hand, causes the opening of the valve 7 of the valve 6 and, on the other hand, creates, upstream, an additional depression in the tube 1, so that the chain 2 is sucked towards the fitting 10 and pushed through the valve 7 between the pair of rollers 12.

A cet instant il est important de noter que le chapelet qui peut être froissé ou en accordéon au niveau de la chambre 5 subit un défroissage du à la retenue de la partie postérieure du chapelet par le moyen d'aspiration 4 et une aspiration de la partie antérieure par l'alimentation 8.At this time it is important to note that the rosary which can be crumpled or in accordion at the level of the chamber 5 undergoes a smoothing due to the retention of the posterior part of the rosary by the suction means 4 and a suction of the anterior by diet 8.

De cette manière, le chapelet parvient dans le séparateur 11 dans de bonnes conditions. Le chapelet est entrainé par la paire de rouleaux 12 vers la paire de rouleaux 13 qui,tournant légèrement plus vite, provoquent la rupture dudit chapelet par unités d'articles.In this way, the rosary reaches the separator 11 in good conditions. The chain is driven by the pair of rollers 12 towards the pair of rollers 13 which, turning slightly faster, cause the said chain to rupture by units of articles.

Au moment où le chapelet est enserré par la paire de rouleaux 12, ceux-ci ont tendance à s'écarter, ce qui actionne le contact 17 qui ferme l'électro-vanne 9 par 11 intermédiaire du relais bi-stable.When the chain is surrounded by the pair of rollers 12, they tend to move apart, which activates the contact 17 which closes the solenoid valve 9 by 1 1 through the bi-stable relay.

Il est évident qu'il est alors possible d'enfiler un autre chapelet de chaussettes et que le cycle peut recommencer dès que l'extrémité du chapelet précédent aura franchi le clapet 7.It is obvious that it is then possible to put on another string of socks and that the cycle can start again as soon as the end of the preceding string has crossed the valve 7.

Le mode de réalisation décrit est donné à titre d'exemple non limitatif et de nombreuses variantes peuvent être imaginées sans sortir du cadre de l'invention. L'invention concerne non seulement les chapelets de chaussettes, mais également toutes sortes d'articles tubulaires comportant un fil de séparation fragile. En outre, l'invention permet évidemment de séparer lesdits chapelets sans avoir obligatoirement recours à un retournement préalable de ceux-ci.The embodiment described is given by way of nonlimiting example and many variants can be imagined without departing from the scope of the invention. The invention relates not only to strings of socks, but also to all kinds of tubular articles comprising a fragile separation thread. In addition, the invention obviously makes it possible to separate said strings without necessarily having to turn them over beforehand.
