Description
La présente invention a pour objet un procédé et une machine pour repasser et empiler des chausettes en automatique.The present invention relates to a method and a machine for ironing and stacking socks automatically.
Il est connu des techniciens du secteur que les machines actuelles pour le repassage à la vapeur des chaussettes comprennent une pluralité de formes plates et verticales, sur lesquelles les chaussettes sont chargées à la main par une opératrice et lesquelles sont associées à des moyens de déplacement correspondants pour permettre leur passage et leur séjour temporaire dans une chambre de vaporisation et de pressage pour effectuer leur repassage.It is known to technicians in the sector that current machines for steam ironing socks include a plurality of flat and vertical shapes, on which the socks are loaded by hand by an operator and which are associated with corresponding displacement means to allow their passage and their temporary stay in a vaporization and pressing chamber for ironing.
Il est également connu que le repassage à sec des chaussettes est effectué directement sur les formes verticales de support respectives, lesquelles sont chauffées électriquement.It is also known that the dry ironing of the socks is carried out directly on the respective vertical support shapes, which are electrically heated.
En particulier on connaît par le document FR-A-962.772 une machine à former les articles de bonneterie comprenant plusieurs formes plates destinées à recevoir les articles à traiter, et montées à la périphérie d'un disque rotatif, tournant par fractions de tour successives et égales et étant immobilisé à la fin de chaque fraction de tour pour le temps necessaire au traitement. La zone de traitement est délimitée par deux plateaux en forme de secteur commandés de se raprocher vis à vis, avec l'interposion de plusieurs formes et presser les articles en position de traitement.In particular, document FR-A-962.772 discloses a machine for forming knitted articles comprising several flat shapes intended to receive the articles to be treated, and mounted on the periphery of a rotary disc, rotating by successive turn fractions and equal and being immobilized at the end of each fraction of a turn for the time necessary for treatment. The treatment zone is delimited by two sector-shaped trays controlled to approach each other, with the interposition of several forms and to press the articles into the treatment position.
On connait aussi par le document US-A-3.842.973 une machine pour traiter des articles tricotés qui comprend un transporteur avec des moyens de motorisation, une forme chaussant l'article, un bras, des moyens pour tourner ladite forme, des moyens pour attacher tournant ledit bras au transporteur, un guide pour mettre en mouvement avec continuité le transporteur et des moyens pour tourner avec intermittance la forme.Also known from document US-A-3,842,973 is a machine for treating knitted articles which comprises a conveyor with motorization means, a form fitting the article, an arm, means for turning said form, means for attaching said arm to the conveyor, a guide for continuously moving the conveyor and means for intermittently turning the shape.
Il est également connu que, à la fin du repassage, les chaussettes sont prélevées manuellement ou en automatique et, ensuite, empilées pour être conditionnées. Pour empiler en automatique les chaussettes qui ont été repassées, on connaît un dispositif comprenant une pince pour la préhension des chaussettes et le dépôt successif sur un plan de support correspondant, destiné à former un élément de butée pour une plaque oscillante de pressage des chaussettes qui y sont déposées.
Mais l'opération d'enfilage des chaussettes à repasser sur les formes de support correspondantes s'effectue avec difficulté, du fait que les formes sont disposées en position verticale, et ceci aussi bien durant l'opération d'enfilage que durant les phases successives du processus de repassage, de sorte que même l'inspection des chaussettes pour la détection d'éventuels défauts s'avère peu pratique. A celà s'ajoute le fait que la séparation des chaussettes défectueuses de celles intactes n'est pas automatique, et par conséquent l'opératrice doit retirer les chaussettes défectueuses des formes de support respectives avant leur repassage, en prélevant le temps sur la phase de chargement des autres formes de la machine et en réduisant ainsi la capacité de production.It is also known that, at the end of ironing, the socks are removed manually or automatically and then stacked to be packaged. To automatically stack the socks which have been ironed, a device is known comprising a clamp for gripping the socks and successively depositing them on a corresponding support plane, intended to form a stop element for an oscillating plate for pressing the socks which are deposited there.
But the operation of putting the socks on ironing on the corresponding support forms is carried out with difficulty, because the forms are arranged in a vertical position, and this both during the threading operation and during the successive phases of the ironing process, so that even the inspecting socks for possible faults is impractical. Added to this is the fact that the separation of defective socks from intact ones is not automatic, and therefore the operator must remove the defective socks from the respective support shapes before ironing them, taking the time from the loading of other forms of the machine and thereby reducing production capacity.
En alternative, une opératrice auxiliaire doit être chargée de l'opération d'extraction des chaussettes défectueuses, ce qui entraîne une augmentation du coût des chaussettes finies. Par ailleurs, avec ces machines connues, il n'est pas possible d'empiler un quelconque nombre prédéterminé de chaussette repassées, du fait que l'abaissement de la plaque de pressage précitée se trouve fortement entravée par l'épaisseur de ces chaussettes qui ont été empilées, lorsqu'elles sont en grand nombre.Alternatively, an auxiliary operator must be responsible for the operation of extracting defective socks, which leads to an increase in the cost of finished socks. Furthermore, with these known machines, it is not possible to stack any predetermined number of ironed socks, since the lowering of the aforementioned pressing plate is greatly hampered by the thickness of these socks which have when stacked in large numbers.
Le but principal de la présente invention est d'éliminer les inconvénients précités.The main object of the present invention is to eliminate the aforementioned drawbacks.

Said chamber (5) can be opened by means of an operating cylinder (50) and a corresponding lever (51) articulated on the chassis of the machine, so as to allow the introduction and pressing of the socks which have been moistened and previously pressed.
Conformément à l'invention, avantageusement et en référence avec les Fig. 2A - 4 des dessins annexés, ladite pince (6) est supportée par un chariot (60) mobile sur un guide rectiligne parallèle à l'axe du pied (14) de la chaussette qui a été repassée et séchée.According to the invention, advantageously and with reference to FIGS. 2A - 4 of the accompanying drawings, said clamp (6) is supported by a carriage (60) movable on a rectilinear guide parallel to the axis of the foot (14) of the sock which has been ironed and dried.
En référence avec la Fig. 5 des dessins annexés, ledit bras (90) de support des embouts aspirants (9) est associé à un cylindre opérateur correspondant (91) au moyen d'un levier (92) qui est relié, d'un côté, au bras (90) et, de l'autre côté, à la tige du cylindre (91), de manière à permettre le soulèvement de la chaussette en maintenant sa position horizontale.With reference to FIG. 5 of the accompanying drawings, said arm (90) for supporting the suction tips (9) is associated with a corresponding operating cylinder (91) by means of a lever (92) which is connected, on one side, to the arm (90 ) and, on the other side, to the cylinder rod (91), so as to allow the lifting of the sock while maintaining its horizontal position.
Le fonctionnement de la machine décrite est le suivant. Lorsqu'une chaussette à repasser est enfilée sur la forme de support (10) correspondante, dans la station A de chargement, l'opératrice inspecte le côté visible de la chaussette. Ensuite, la plaque (1) tourne d'un arc de cercle correspondant à un pas. Cette rotation provoque l'engagement du palpeur (15) de ladite forme (10) avec la came (3) de commande de la rotation des formes autour des arbres respectifs (13). De cette manière, la forme (10) avec la chaussette qui a été inspectée d'un côté se place sensiblement tangente par rapport à la plaque (1), en présentant l'autre côté à l'opératrice, qui effectue son inspection. Au terme de l'inspection des deux côtés, en cas de présence de défauts sur au moins un des deux côtés de la chaussette, l'opératrice signale la position de la forme (10) sur laquelle celle-ci est enfilée, en agissant simplement sur un bouton-poussoir associé au système de contrôle PLC de manière que ladite position soit mémorisée. Successivement, la chaussette est humidifiée et pressée dans la chambre (4) et, ensuite, pressée ultérieurement et séchée dans la chambre (5). Au terme de la phase de séchage, la pince (6) effectue l'extraction de la chaussette de la forme correspondante (10). Durant la phase initiale de cette opération, la pince (6) présente une mâchoire au-dessus de la chaussette et l'autre mâchoire au-dessous du transporteur à bande (7) et agit en correspondance du pied (14) de la chaussette, de manière à permettre son extraction dans la direction du prolongement de l'axe du pied (14), comme conséquence du mouvement du chariot (60). Au terme de cette extraction, la pince (6) libère la chaussette, laquelle, de cette manière, se trouve en appui sur la bande (7) et est transportée par celle-ci en correspondance des embouts (9) d'empilage des chaussettes. Ensuite, sur commande du système de contrôle PLC précité, le bras (90) de support des embouts (9) est abaissé et l'aspiration de l'air est activée à travers ces derniers (9), pour permettre le prélèvement de la chaussette ainsi transportée. Successivement, le bras (90) est soulevé au moyen du cylindre (91) correspondant jusqu'à amener la chaussette à la hauteur de la bande d'appui des chaussettes à empiler. Dans le cas où la chaussette est défectueuse, le système PLC ne commande pas l'abaissement du bras (90) et, par conséquent, la chaussette défectueuse disposée sur la bande (7) est déchargée dans le récipient (8) de récupération des rebuts. Les chaussettes ainsi empilées sur ladite bande d'appui, en un nombre prédéterminé de paires, sont ensuite retirées à la main ou en automatique pour effectuer leur conditionnement successif.The operation of the machine described is as follows. When an ironing sock is put on the corresponding support form (10), in the loading station A, the operator inspects the visible side of the sock. Then, the plate (1) rotates in an arc corresponding to a step. This rotation causes the engagement of the feeler (15) of said shape (10) with the cam (3) for controlling the rotation of the shapes around the respective shafts (13). In this way, the shape (10) with the sock which has been inspected on one side is placed substantially tangent with respect to the plate (1), presenting the other side to the operator, who performs her inspection. At the end of the inspection on both sides, if there are defects on at least one of the two sides of the sock, the operator signals the position of the shape (10) on which it is threaded, by simply acting on a push button associated with the PLC control system so that said position is memorized. Subsequently, the sock is moistened and pressed in the chamber (4) and then subsequently pressed and dried in the chamber (5). At the end of the drying phase, the clamp (6) extracts the sock from the corresponding shape (10). During the initial phase of this operation, the clamp (6) has a jaw above the sock and the other jaw below the belt conveyor (7) and acts in correspondence with the foot (14) of the sock, so as to allow its extraction in the direction of the extension of the axis of the foot (14), as a consequence of the movement of the carriage (60). At the end of this extraction, the clamp (6) releases the sock, which, in this way, is supported on the strip (7) and is transported by the latter in correspondence with the ends (9) for stacking the socks . Then, on command of the abovementioned PLC control system, the arm (90) for supporting the tips (9) is lowered and the air suction is activated through the latter (9), to allow the removal of the sock thus transported. Successively, the arm (90) is raised by means of the corresponding cylinder (91) until the sock is brought up to the height of the support strip of the socks to be stacked. In the event that the sock is defective, the PLC system does not control the lowering of the arm (90) and, consequently, the defective sock placed on the strip (7) is discharged into the container (8) for collecting scrap. The socks thus stacked on said support strip, in a predetermined number of pairs, are then removed by hand or automatically to carry out their successive packaging.
