Description

La présente invention a pour objet un dispositif d'assemblage de la tige et de la semelle d'une chaussure, dans une installation au moins partiellement automatisée de fabrication de chaussures.The present invention relates to a device for assembling the upper and the sole of a shoe, in an at least partially automated installation for manufacturing shoes.

Dans le cadre d'une telle installation de fabrication de chaussures, il est prévu un convoyeur destiné au transport de plateaux dont certains portent des formes qui sont tout d'abord revêtues des tiges, et dont d'autres portent des semelles.In the context of such a shoe manufacturing installation, there is provided a conveyor intended for the transport of trays, some of which have shapes which are first coated with rods, and others of which carry soles.

Le but de l'invention est de fournir un dispositif d'assemblage qui offre le maximum de possibilités de réalisation de chaussures, en permettant pour les chaussures dont la semelle possède une forme simple, telle qu'une cuvette, un assemblage entièrement automatique, alors que dans d'autres types de chaussures où la semelle est plus complexe, il doit être recouru à un assemblage au moins partiellement manuel.The object of the invention is to provide an assembly device which offers the maximum number of possibilities for making shoes, by allowing for shoes whose sole has a simple shape, such as a bowl, a fully automatic assembly, so than in other types of footwear where the sole is more complex, it must be used at least partially manual assembly.

A cet effet, le dispositif qu'elle concerne comporte :

  • une table possédant plusieurs pistes perpendiculaires au convoyeur et munies chacune d'un dispositif de transfert d'un plateau entre le convoyeur et une position de référence éloignée de celui-ci, les pistes étant destinées à recevoir des plateaux portant les tiges et les semelles pour la réalisation de plusieurs paires de chaussures,
  • un robot de transfert situé du côté de la table opposé au convoyeur,
  • une presse située d'un côté du robot, et
  • un poste d'assemblage manuel de tiges et de semelles, situé de l'autre côté du robot.
To this end, the device it concerns includes:
  • a table having several tracks perpendicular to the conveyor and each provided with a device for transferring a tray between the conveyor and a reference position remote from the latter, the tracks being intended to receive trays carrying the rods and the soles for making several pairs of shoes,
  • a transfer robot located on the side of the table opposite the conveyor,
  • a press located on one side of the robot, and
  • a manual assembly station for uppers and soles, located on the other side of the robot.

Les plateaux sont identifiés par un dispositif à mémoire indiquant le type de produits qu'il porte, tige ou semelle, et également le mode d'assemblage du produit, assemblage automatique ou assemblage manuel. Un calculateur associé à l'installation commande alors le robot soit pour réaliser l'assemblage automatique, soit pour transférer la tige vers le poste d'assemblage manuel.The trays are identified by a memory device indicating the type of products it carries, upper or sole, and also the method of product assembly, automatic assembly or manual assembly. A computer associated with the installation then controls the robot either to perform automatic assembly, or to transfer the rod to the manual assembly station.

Avantageusement, la table est équipée, dans chaque zone correspondant à la position de référence d'un plateau portant une semelle, de griffes montées sur des vérins, formant des écarteurs destinés à ouvrir le rebord de la semelle pour faciliter le montage de la tige sur celle-ci.Advantageously, the table is equipped, in each zone corresponding to the reference position of a plate carrying a sole, with claws mounted on jacks, forming spacers intended to open the rim of the sole to facilitate mounting of the rod on this one.

Suivant une caractéristique de l'invention dans le cas de formes permettant un assemblage simple de la tige et de la semelle, les moyens de commande provoquent successivement la prise par le bras du robot d'une forme équipée d'une tige, son retournement et son transfert vers la semelle contre laquelle la forme et la tige sont appliquées après écartement des bords de la semelle, l'assemblage ainsi obtenu grâce à la réactivation de la colle que comporte localement la semelle et/ou la tige, effectuée lors de l'arrivée des plaques sur la table, étant ensuite transféré par le robot à la presse, qui maintient l'ensemble en pression pendant le temps de séchage de la colle, avant un nouveau transfert sur le plateau de la table qui, à l'origine a servi à l'amenée de la forme équipée de la tige.According to a characteristic of the invention in the case of forms allowing a simple assembly of the upper and the sole, the means control successively cause the robot arm to take up a shape fitted with a rod, turn it over and transfer it to the sole against which the shape and the rod are applied after the edges of the sole have been separated, the assembly thus obtained thanks to the reactivation of the glue that the sole and / or the upper contains locally, carried out when the plates arrive on the table, then being transferred by the robot to the press, which keeps the assembly under pressure during the drying time of the glue, before a new transfer on the table top, which originally served to bring the form equipped with the rod.

En outre, la presse comprend au moins un support muni de moyens de réception de la forme équipée de la tige et de la semelle, identiques à ceux équipant les plateaux destinés aux transport des formes.In addition, the press comprises at least one support provided with means for receiving the form equipped with the upper and the sole, identical to those equipping the plates intended for transporting the forms.

Les moyens de réception de la forme peuvent être constitués, par exemple, par deux doigts verticaux et profilés, tandis que la forme est équipée, pour sa part, de deux éléments tubulaires complémentaires, chaque élément tubulaire pouvant comporter, à sa périphérie, au moins une gorge en vue de la préhension par le bras du robot.The means for receiving the form can be constituted, for example, by two vertical and profiled fingers, while the form is equipped, for its part, with two complementary tubular elements, each tubular element possibly comprising, at its periphery, at least a groove for gripping by the robot arm.

Suivant une autre caractéristique de l'invention le poste d'assemblage manuel d'une tige et d'une semelle comporte une colonne fixée au sol et sur la partie supérieure de laquelle une platine est montée pivotante sous l'action d'un vérin entre une position horizontale et une position sensiblement verticale, cette platine portant un support muni de moyens de réception de la forme équipée de la tige, identiques à ceux équipant les plateaux destinés aux transport des formes, et de moyens de blocage de la forme.According to another characteristic of the invention, the manual assembly station of a rod and a sole comprises a column fixed to the ground and on the upper part of which a plate is pivotally mounted under the action of a jack between a horizontal position and a substantially vertical position, this plate carrying a support provided with means for receiving the form equipped with the rod, identical to those equipping the plates intended for transporting the forms, and means for blocking the form.

Le robot amène la forme équipée de la tige, alors que la platine du poste d'assemblage est en position horizontale. L'opérateur provoque le pivotement de cette platine en position verticale pour pouvoir procéder plus aisément à l'assemblage de la semelle sur la tige.The robot brings the form equipped with the rod, while the plate of the assembly station is in a horizontal position. The operator causes this plate to pivot in a vertical position in order to be able to more easily assemble the sole on the upper.

Afin de faciliter cette opération, la platine est également montée pivotante autour d'un axe qui en est perpendiculaire, et est associée à un vérin rotatif destiné à assurer son mouvement de retour vers la position de référence, après l'assemblage de la semelle et de la tige, pour permettre sa préhension par le bras du robot.In order to facilitate this operation, the plate is also pivotally mounted about an axis which is perpendicular to it, and is associated with a rotary actuator intended to ensure its return movement towards the reference position, after assembly of the sole and of the rod, to allow its gripping by the robot arm.

L'opérateur peut alors faire pivoter librement la platine et la forme montée sur elle autour de ce second axe pour réaliser l'assemblage de la semelle. Lorsque cet assemblage est terminé, il suffit à l'opérateur d'actionner une commande qui provoque grâce au vérin rotatif et au vérin de pivotement autour d'un axe horizontal le retour de la platine en position horizontale, avec indexation dans la position de référence pour la prise de l'ensemble tige et semelle par le bras du robot.The operator can then freely rotate the plate and the form mounted on it around this second axis to carry out the assembly. of the sole. When this assembly is completed, the operator need only activate a command which, by means of the rotary actuator and the pivoting actuator about a horizontal axis, returns the plate to the horizontal position, with indexing in the reference position. for the grip of the upper and sole assembly by the robot arm.

Il est important, compte tenu des différents mouvements auxquels peut être soumise la tige, de parfaitement immobiliser la forme qui porte la tige sur la platine, cette immobilisation étant obtenue par exemple par action de la tige d'un vérin dont l'extrémité pénètre dans une encoche ménagée dans la forme, et notamment dans un élément tubulaire supportant cette forme. Il est également important que la position de chaque semelle qui arrive sur la table soit parfaitement identifiée en fonction de la taille de la semelle.It is important, taking into account the different movements to which the rod may be subjected, to perfectly immobilize the shape which carries the rod on the plate, this immobilization being obtained for example by action of the rod of a jack whose end penetrates into a notch formed in the shape, and in particular in a tubular element supporting this shape. It is also important that the position of each sole that arrives on the table is perfectly identified according to the size of the sole.

A cet effet, chaque semelle repose sur une plaque elle-même montée sur un plateau à l'aide des mêmes moyens de positionnement que ceux utilisés pour les formes, cette plaque portant, sur sa face supérieure, une butée arrière fixe, deux butées latérales et une butée avant mobile longitudinalement et soumise à l'action de ressorts tendant à la déplacer vers l'arrière.To this end, each sole rests on a plate itself mounted on a plate using the same positioning means as those used for the shapes, this plate carrying, on its upper face, a fixed rear stop, two lateral stops. and a front stop movable longitudinally and subjected to the action of springs tending to move it backwards.

La référence du positionnement de chaque semelle se fait donc à partir du talon de celle-ci, dont la position est toujours la même quelle que soit la taille de la semelle.The reference for the positioning of each sole is therefore made from the heel thereof, the position of which is always the same regardless of the size of the sole.

De toute façon, l'invention sera bien comprise à l'aide de la description qui suit, en référence au dessin schématique annexé représentant, à titre d'exemple non limitatif une forme d'exécution de ce dispositif :

Le dispositif selon l'invention est associé à un convoyeur 2 destiné au transport de plateaux 3 dont certains portent des formes 4 revêtues de tiges 5, et dont les autres portent des semelles 6.The device according to the invention is associated with a conveyor 2 intended for the transport of trays 3, some of which have shapes 4 coated with rods 5, and the others of which carry soles 6.

Le dispositif comprend une table 7 comportant quatre pistes 8 perpendiculaires au convoyeur et munies chacune d'un dispositif de transfert 9 possédant notamment un vérin, ce dispositif étant susceptible de déplacer un plateau 3 entre le convoyeur, où le plateau 3 est immobilisé par des butées d'arrêt 10, et une position de référence éloignée du convoyeur. Le dispositif de transfert est également destiné à faire parcourir le trajet inverse au plateau, c'est-à-dire depuis la position de référence éloignée du convoyeur jusqu'au convoyeur.The device comprises a table 7 comprising four tracks 8 perpendicular to the conveyor and each provided with a transfer device 9 having in particular a jack, this device being capable of moving a plate 3 between the conveyor, where the plate 3 is immobilized by stops stop 10, and a reference position remote from the conveyor. The transfer device is also intended to make the reverse path pass through the plate, that is to say from the reference position remote from the conveyor to the conveyor.

Le dispositif représenté à la figure 1 comporte une table 7 équipée de quatre pistes 8, ce qui permet d'avoir simultanément sur la table quatre plateaux dont deux portent des formes 4 et dont les deux autres portent des semelles 6.The device represented in FIG. 1 comprises a table 7 equipped with four tracks 8, which makes it possible to have simultaneously on the table four trays, two of which carry shapes 4 and the other two of which carry soles 6.

Du côté de la table opposée au convoyeur est disposé un robot 12, de part et d'autre duquel sont montés, d'une part, une presse 13 à deux zones d'assemblage et d'autre part, un poste 14 d'assemblage manuel à deux zones d'assemblage.On the side of the table opposite the conveyor is arranged a robot 12, on either side of which are mounted, on the one hand, a press 13 with two assembly zones and on the other hand, an assembly station 14 manual with two assembly zones.

Chaque semelle 6 repose, non pas directement sur un plateau 3, mais sur une plaque 15. Chaque plaque 15 est munie de deux parties tubulaires 16 faisant saillie vers le bas, engagées sur deux doigts 17 faisant saillie de la face supérieure d'un plateau. Dans leur partie inférieure les éléments tubulaires 16 présentent des encoches 18 permettant la préhension par le bras du robot 12.Each sole 6 rests, not directly on a plate 3, but on a plate 15. Each plate 15 is provided with two tubular parts 16 projecting downwards, engaged on two fingers 17 projecting from the upper face of a plate . In their lower part, the tubular elements 16 have notches 18 allowing gripping by the robot arm 12.

La plaque 15 comporte, comme représenté notamment à la figure 5, des butées fixes 19 à l'arrière, pour immobiliser le talon, des butées latérales 20 réglables, et une butée avant 22 déplaçable en direction de l'arrière par l'intermédiaire d'un ressort 23. En conséquence, le positionnement de chaque semelle 6 en fonction de la taille de la semelle est repéré à partir de son talon puisque c'est la butée 19 de talon qui est le point de référence fixe.The plate 15 comprises, as shown in particular in Figure 5, fixed stops 19 at the rear, to immobilize the heel, adjustable lateral stops 20, and a front stop 22 movable in the rear direction via d 'a spring 23. Consequently, the positioning of each sole 6 as a function of the size of the sole is identified from its heel since it is the heel stop 19 which is the fixed reference point.

Comme montré à la figure 2, chaque piste 8 destinée à recevoir un plateau 3 équipé d'une semelle 6, est associée à des éléments à griffes 25 montés sur des vérins 26, formant des écarteurs susceptibles de déplacer vers l'extérieur le bord 21 d'une semelle en forme générale de cuvette. Lorsque les formes respectivement de la tige 5 et d'une semelle 6 correspondante sont suffisamment simples l'assemblage peut être réalisé automatiquement. A cet effet, le robot assure la préhension de la forme 4, par l'intermédiaire des parties tubulaires 27 de celles-ci engagées sur les doigts 17 du plateau 3, assure le retournement de la forme et vient appliquer celle-ci équipée de la tige 5 sur la semelle 6. Compte tenu de la réactivation de la colle à l'intérieur d'un four 31 lors de l'amenée des plateaux sur la table 7, il se produit une adhérence entre la semelle et la tige. Pour parfaire cette adhérence, l'ensemble est transféré par le robot 12 vers la presse 13, où la forme est engagée par l'intermédiaire de ses parties tubulaires 27 sur des tiges 28 analogues aux tiges 17 des plateaux 3. Pendant la phase de maintien en pression de la semelle sur la tige, le robot procède à une autre opération, telle que par exemple le transfert de l'ensemble forme + tige + semelle de la zone voisine de la presse vers un plateau 3 libre, pour l'évacuation de l'assemblage ainsi réalisé vers le poste suivant.As shown in Figure 2, each track 8 intended to receive a plate 3 equipped with a sole 6, is associated with claw elements 25 mounted on jacks 26, forming spacers capable of moving outward the edge 21 of a sole in the general shape of a bowl. When the shapes respectively of the upper 5 and of a corresponding sole 6 are sufficiently simple, the assembly can be carried out automatically. To this end, the robot grips the form 4, by means of the tubular parts 27 of these engaged on the fingers 17 of the plate 3, ensures the reversal of the form and comes to apply it equipped with the rod 5 on the sole 6. Taking into account the reactivation of the glue inside an oven 31 when the plates are brought onto the table 7, adhesion occurs between the sole and the rod. To perfect this adhesion, the assembly is transferred by the robot 12 to the press 13, where the shape is engaged by means of its tubular parts 27 on rods 28 similar to the rods 17 of the plates 3. During the holding phase in pressure from the sole to the upper, the robot performs another operation, such as for example the transfer of the shape + upper + sole assembly from the area adjacent to the press to a free plate 3, for the evacuation of the assembly thus carried out to the next station.

Dans la mesure où les formes de la tige et/ou de la semelle sont complexes, il est possible de procéder à un assemblage manuel. A cet effet, le robot 12 assure, dans les conditions indiquées précédemment, le transfert de la forme et de la tige vers le poste d'assemblage manuel 14. Celui-ci comporte une colonne 29 verticale sur la partie supérieure de laquelle est montée une platine 30. Cette platine 30 est susceptible de pivoter entre une position horizontale représentée à la figure 3 jusque dans une position verticale représentée à la figure 4 par l'intermédiaire d'un vérin 32. Cette platine 30 peut également pivoter autour d'un axe, qui en est perpendiculaire, ce second mouvement de pivotement étant associé à un vérin tournant 33. La platine 30 comporte deux doigts 34 analogues aux doigts 17 des plateaux 3, destinés à recevoir la forme 4. En pratique, la forme 4 est amenée sur la platine dans la position de figure 3. L'opérateur provoque alors l'actionnement du vérin 32 qui amène la platine en position verticale. Dans cette position, la platine peut tourner librement autour de son second axe qui est maintenant horizontale. Dans cette position, la platine peut tourner librement autour de son second axe qui est maintenant horizontal, permettant à l'opérateur de procéder à l'assemblage de la semelle, cette semelle étant à disposition de l'opérateur par exemple dans une boîte, ou étant amenée par le robot 12. Afin d'éviter que la forme n'échappe à la platine, il est prévu un vérin de blocage 35, dont l'extrémité de la tige est équipée d'un taquet 36 pénétrant dans un évidement d'un élément tubulaire 27 de la forme. Après assemblage de la semelle sur la tige, l'opérateur commande le retour de l'ensemble forme + tige + semelle dans la position d'origine représentée à la figure 3, cette position mémorisée étant obtenue grâce aux mouvements des vérins 32 et 33.Since the shapes of the upper and / or the sole are complex, manual assembly is possible. To this end, the robot 12 ensures, under the conditions indicated above, the transfer of the shape and the rod to the manual assembly station 14. This comprises a vertical column 29 on the upper part of which is mounted a plate 30. This plate 30 is able to pivot between a horizontal position shown in FIG. 3 as far as a vertical position shown in FIG. 4 by means of a jack 32. This plate 30 can also pivot around an axis , which is perpendicular thereto, this second pivoting movement being associated with a rotary actuator 33. The plate 30 comprises two fingers 34 similar to the fingers 17 of the plates 3, intended to receive the form 4. In practice, the form 4 is brought to the plate in the position of Figure 3. The operator then causes actuation of the jack 32 which brings the plate in the vertical position. In this position, the plate can rotate freely around its second axis which is now horizontal. In this position, the plate can rotate freely around its second axis which is now horizontal, allowing the operator to proceed with the assembly. of the sole, this sole being available to the operator for example in a box, or being brought by the robot 12. In order to prevent the shape from escaping from the plate, a blocking cylinder 35 is provided, the end of the rod of which is fitted with a cleat 36 penetrating into a recess of a tubular element 27 of the shape. After assembling the sole on the upper, the operator controls the return of the form + upper + sole assembly to the original position shown in FIG. 3, this memorized position being obtained by means of the movements of the jacks 32 and 33.

Le bras du robot reprend alors l'assemblage pour l'amener sur un plateau 3 en attente dans le magasin, ce plateau 3 étant évacué par le vérin 9 vers le convoyeur 2 pour la poursuite de la fabrication de la chaussure.The robot arm then resumes assembly to bring it to a tray 3 waiting in the store, this tray 3 being evacuated by the jack 9 to the conveyor 2 for the further manufacture of the shoe.
