Elle se caractérise par le fait qu'un article chaussant peut être déposé automatiquement ou manuellement sur deux doigts mobiles l'un par rapport à l'autre dans un plan vertical, l'ensemble constituant un poste fixé sur un plateau circulaire, appelé tourelle, et qui en compte quatre.It is characterized by the fact that a footwear can be placed automatically or manually on two fingers movable relative to each other in a vertical plane, the assembly constituting a station fixed on a circular plate, called turret, and who has four.
Elle se caractérise en ce que les doigts mobiles peuvent à chaque poste se rapprocher ou s'éloigner symétriquement l'un de l'autre au moyen de deux crémaillères solidaires des supports doigts qui viennent s'engrener avec un engrenage tourillonnant sur un axe fixé sur un support solidaire de la tourelle et que le rapprochement des doigts est assuré par une pièce en forme de U animée d'un mouvement vertical au moyen d'un vérin qui agit sur un galet fixé sur le support inférieur du doigt, pendant la rotation de la tourelle les doigts sont maintenus écartés par les galets qui roulent sous un disque solidaire du bâti.It is characterized in that the movable fingers can at each station move toward or away symmetrically from one another by means of two integral racks of the finger supports which come to mesh with a gear journalled on an axis fixed on a support secured to the turret and that the approximation of the fingers is provided by a U-shaped piece animated by a vertical movement by means of a jack which acts on a roller fixed on the lower support of the finger, during the rotation of the turret the fingers are kept apart by the rollers which roll under a disk integral with the frame.
Elle se caractérise en ce que les doigts sont au 1er poste rassemblés l'un contre l'autre pour permettre de déposer un article côté revers de celui-ci sur les doigts supérieur et inférieur ayant une forme particulière, pour retenir l'article, comportant un évidement au milieu et une extrémité semi sphérique, qu'ils sont ensuite écartés pour tendre l'article qui est ainsi solidement maintenu pendant la rotation de la tourelle.It is characterized in that the fingers are at the 1st station together against one another to allow to deposit an article on the reverse side thereof on the upper and lower fingers having a particular shape, to retain the article, having a recess in the middle and a semi-spherical end, they are then spaced to stretch the article which is thus firmly held during the rotation of the turret.
Elle se caractérise en ce que les doigts au 2ème poste sont dans un premier temps en position d'ouverture complète, pour permettre à un tube de diamètre approprié en fonction de l'article duquel sort un flux d'air à l'extrémité du dit tube, l'extrémité tronconique de celui-ci pénétrant à l'intérieur de l'article, le déplacement du tube étant assuré par l'intermédiaire d'un mécanisme de positionnement approprié.It is characterized in that the fingers at the 2 nd station are initially in the fully open position, to allow a tube of appropriate diameter according to the article which exits a flow of air at the end of the said tube, the frustoconical end thereof penetrating inside the article, the displacement of the tube being ensured by means of a suitable positioning mechanism.
Elle se caractérise par le fait que l'article est maintenu sur les doigts du 2ème poste, au moyen d'une fourchette amovible de forme particulière de manière à maintenir l'article sur les doigts pendant la pénétration du tube à l'intérieur de l'article, et que ladite fourchette s'escamote pour libérer l'article lors de son orientation.It is characterized in that the article is held on the fingers of the 2 nd station, by means of a removable fork particular shape so as to maintain the article on the fingers during the penetration of the tube inside article, and that said fork retracts to release the article during its orientation.
Elle se caractérise également en ce que les doigts au 2ème poste sont dans un deuxième temps rétractés à l'intérieur de deux grandes coulisses longitudinales, pratiquées sur une longueur appropriée du tube, et diamétralement opposés, pour permettre l'orientation de l'article autour du tube au moyen de 2 rouleaux.It is also characterized in that the fingers at the 2 nd station are in a second time retracted inside two large longitudinal slides, made on an appropriate length of the tube, and diametrically opposed, to allow the orientation of the article around the tube by means of 2 rollers.
Une des caractéristiques est de permettre l'orientation d'un article enfilé sur un tube, les doigts étant rétractés à l'intérieur du tube dans les deux grandes coulisses et la fourchette amovible étant en position de recul, au moyen de 2 rouleaux qui viennent pincer l'article enfilé sur le tube, uniquement sur la tige de l'article, de part et d'autre de celui-ci et qui animés d'un mouvement de rotation dans le même sens au moyen d'un mécanisme approprié va faire tourner l'article autour du tube.One of the features is to allow the orientation of an article threaded onto a tube, the fingers being retracted inside the tube in the two large slides and the detachable fork being in the retracted position, by means of two rollers that come pinching the article threaded on the tube, only on the stem of the article, on both sides of it and which rotated in the same direction by means of a suitable mechanism will make turn the article around the tube.
Elle se caractérise également en ce que les doigts du 2ème poste vont dans un troisième temps reprendre leur position d'ouverture complète, et de ce fait, les doigts vont récupérer l'article, ce qui va permettre de retirer les deux rouleaux d'orientation, et le tube de l'intérieur de l'article.It is also characterized in that the fingers of the 2 nd post go in a third time to resume their full open position, and because of this, the fingers will recover the article, which will allow to remove the two rolls of orientation, and the tube from the inside of the article.
L'une de ces caractéristiques est du fait que l'article est enfilé sur un tube uniquement au niveau de la tige dudit article et que le pied de l'article tendu par le flux d'air sortant dudit tube avec une orientation correspondant à la forme du pied d'une chaussette normale, peut être détecté au moyen d'une cellule photoélectrique et de ce fait être positionné en rotation par les rouleaux toujours de la même manière, et ceci en fonction de la cellule de détection quelque soit la taille de l'article.One of these features is that the article is threaded on a tube only at the stem of said article and that the foot of the article stretched by the air flow out of said tube with an orientation corresponding to the shape of the foot of a normal sock, can be detected by means of a photocell and thus be positioned in rotation by the rollers always in the same way, and this depending on the sensor cell regardless of the size of Article.
Elle se caractérise en ce qu'au 3ème poste de la tourelle, les doigts sont en position d'ouverture complète et que l'article saisi est récupéré par un ensemble de quatre pinces pivotantes et commandées qui viennent s'introduire à l'intérieur et à l'extérieur de l'article tendu entre les 2 doigts, ce qui forme 2 parois verticales, constituées par le revers de l'article avec un espace entre elles égal à l'épaisseur des doigts.It is characterized in that in the 3 rd position of the turret, the fingers are in complete open position and the article before it is recovered by a set of four pivoting controlled clamps, and which come to introduce inside and outside the article stretched between the 2 fingers, which forms 2 vertical walls, constituted by the back of the article with a space between them equal to the thickness of the fingers.
Elle se caractérise également en ce que les pinces intérieures sont articulées sur un axe et commandées par un mécanisme approprié, actionné lui-même par un vérin pour chaque pince, ce qui permet de les ouvrir vers l'extérieur, quand l'ensemble des pinces remonte le long de l'article et, de ce fait, ne remonte pas celui-ci.It is also characterized in that the inner clamps are articulated on an axis and controlled by a suitable mechanism, itself actuated by a jack for each clamp, which allows them to open to the outside, when the set of clamps goes back along the article and, therefore, does not go up this one.
Elle se caractérise également par le fait que les pinces extérieures sont articulées sur un axe et commandées par un mécanisme approprié, actionné lui-même par un vérin, ce qui permet de les ouvrir vers l'extérieur pour pénétrer dans l'article, et de les fermer vers l'intérieur pour saisir le revers de l'article et le maintenir fortement contre les pinces intérieures, et ensuite de les ouvrir quand l'article est enfilé sur une forme permettant ainsi de dégager lesdites pinces de l'article.It is also characterized by the fact that the outer clamps are articulated on an axis and controlled by a suitable mechanism, itself actuated by a jack, which allows them to open outwards to enter the article, and to closing them inwards to grasp the back of the article and hold it firmly against the inner pliers, and then open them when the article is threaded onto a shape thus making it possible to release said pliers from the article.
Elle se caractérise également par le fait que l'ensemble des pinces intérieures et extérieures est monté articulé à l'extrémité d'un bras télescopique pivotant lui-même au moyen d'un mécanisme lui permettant de se déplacer dans l'espace et d'occuper toutes les positions dans un plan vertical dans un sens positif ou négatif, permettant entre autres aux pinces ouvertes de s'engager dans un sens à l'intérieur du revers de l'article avant pinçage et de dégager l'article des doigts après pinçage de celui-ci et d'enfiler dans l'autre sens l'article sur la forme.It is also characterized by the fact that the set of inner and outer claws is mounted articulated to the end of a telescopic arm pivoting itself by means of a mechanism allowing it to move in space and to occupy all positions in a vertical plane in a positive or negative direction, allowing inter alia for the open tongs to engage in a direction on the inside of the back of the article before pinching and to clear the article of the fingers after clamping of it and put the article on form in the other direction.
L'une de ces caractéristiques est que la position des pinces articulées sur un axe est contrôlée par un galet appliqué sur une rampe de forme adéquate, au moyen d'un vérin de tirage pneumatique, permettant ainsi aux pinces d'avoir la bonne inclinaison par rapport à la forme et ceci tout le long de son parcours.One of these features is that the position of the articulated pliers on an axis is controlled by a roller applied on a ramp of suitable shape, by means of a pneumatic drawing ram, thus allowing the pliers to have the correct inclination by relation to form and this all along its course.
Une autre caractéristique de l'invention réside dans le fait que les pinces, montées à l'extrémité du bras télescopique, sont contrôlées en déplacement dans un plan vertical de l'espace, au moyen d'une rampe de forme appropriée, et d'un galet solidaire de l'extrémité du bras télescopique, appliqué sur ladite rampe au moyen d'un vérin pneumatique, permettant aux pinces de s'éloigner ou de se rapprocher de l'axe d'articulation du bras télescopique, ce qui a pour effet de permettre aux pinces de suivre rigoureusement le tracé d'une forme classique, et particulièrement de franchir le talon de la forme.Another feature of the invention lies in the fact that the clamps, mounted at the end of the telescopic arm, are controlled in displacement in a vertical plane of the space, by means of a ramp of appropriate shape, and of a roller secured to the end of the telescopic arm, applied to said ramp by means of a pneumatic cylinder, allowing the clamps to move away from or closer to the axis of articulation of the telescopic arm, which has the effect of to allow the claws to follow rigorously the outline of a classical form, and particularly to cross the heel of the form.
Une autre caractéristique de l'invention consiste en ce que l'ensemble des pinces et du bras télescopique et articulé sur un axe sont fixes sur un mécanisme de translation horizontal, ce qui permet aux pinces de se déplacer dans 3 plans verticaux sous l'action de deux vérins.Another feature of the invention is that all of the clamps and the telescopic arm and articulated on an axis are fixed on a horizontal translation mechanism, which allows the clamps to move in 3 vertical planes under the action two cylinders.
Le 1er plan situé dans l'axe des doigts du 3ème poste de la tourelle permet aux pinces en position ouverte de pénétrer dans l'article, et ensuite après fermeture des pinces de dégager l'articles des doigts en avant de celles-ci. 1 plane situated in the axis of the fingers of the 3 rd position of the turret allows the clamps in open position to penetrate into the article, and then after closing of the grippers to release the sections of the fingers in front thereof .
Le 2ème plan permet aux pinces porteur de l'article de se dégager du plan des doigts de la tourelle, et de permettre à l'ensemble des pinces de venir dans une position située entre 2 formes.The 2 nd plane allows carrier gripper section from disengaging from the plane of the fingers of the turret, and to allow all clips to come into a position between two forms.
Le 3ème plan permet aux pinces d'être dans le plan de déplacement des formes et de ce fait de mettre les pinces en position de départ pour enfiler l'article sur une forme.The 3rd plan allows clips to be in the displacement plane of the forms and thereby to put the clamps in start position to put the article on a form.
L'invention se caractérise également par le fait que l'ensemble des pinces, du bras télescopique et du mécanisme de translation horizontal, peut se déplacer verticalement au moyen d'un dispositif de translation mécanique d'un moto-réducteur et d'une transmission, ce qui permet aux pinces, après avoir effectué l'enfilage du pied au moyen du bras enfileur et potentiellement le passage du talon, de terminer l'enfilage en tirant l'article vers le bas.The invention is also characterized in that all the clamps, the telescopic arm and the horizontal translation mechanism, can move vertically by means of a mechanical translation device of a geared motor and a transmission. , which allows the clamps, after threading the foot by means of the threader arm and potentially the passage of the heel, to complete the threading by pulling the article down.
Elle se caractérise également par le fait que, après avoir terminé l'enfilage, les pinces extérieures s'ouvrent pour libérer l'article à une hauteur déterminée, commandée par un capteur réglable en hauteur et que les pinces intérieures s'ouvrent également vers l'extérieur à l'arrêt du mobile en position basse l'article étant dégagé, et ceci pour permettre aux pinces intérieures et extérieures de se dégager vers le haut sans remonter l'article et de revenir en attente au point de départ du cycle.It is also characterized by the fact that, after completing the threading, the outer clamps open to release the article to a determined height, controlled by a height-adjustable sensor and that the inner clamps also open to the outside. outside the mobile stop in the low position the article being cleared, and this for allow the inner and outer clamps to disengage upward without rewinding the item and return to standby at the starting point of the cycle.
