Description

La présente invention se rapporte à une forme destinée à permettre la fabrication d'une chaussure autour de celle-ci.The present invention relates to a form intended to allow the manufacture of a shoe around it.

Pour la fabrication des chaussures, il est généralement fait usage de "formes" en bois reproduisant les diverses caractéristiques du pied : dimensions pied gauche ou pied droit, ainsi que le type et l'aspect de la chaussure. C'est sur la "forme" que la tige, ou empeigne de la chaussure est adaptée, puis que la "première" est mise en place par clouage (cramponnage), et qu'ultérieurement toutes les autres opérations sont effectuées.For the manufacture of shoes, use is generally made of wooden "shapes" reproducing the various characteristics of the foot: dimensions left foot or right foot, as well as the type and appearance of the shoe. It is on the "shape" that the upper, or upper of the shoe is adapted, then that the "first" is put in place by nailing (cramponnage), and that subsequently all the other operations are carried out.

Toutes ces opérations sont à l'heure actuelle réalisées manuellement, la forme munie de sa tige de chaussure étant transportée manuellement d'une machine à une autre (par exemple, machine de brochage, fraiseuse, verreuse, machine à coudre...). L'automatisation de la fabrication des chaussures, qui est de plus en plus souhaitée à l'heure actuelle pour des raisons évidentes d'augmentation de productivité, n'est pratiquement pas concevable avec les "formes" connues actuellement car celles-ci ne sont actuellement équipées que d'un moyen de préhension assez rudimentaire et en tous cas inadapté aux impératifs de précision nécessaires pour permettre une mise en oeuvre d'automatisation par robotique.All these operations are currently carried out manually, the shape provided with its shoe upper being transported manually from one machine to another (for example, broaching machine, milling machine, glassmaker, sewing machine ...). The automation of the manufacture of shoes, which is more and more desired at present for obvious reasons of increase in productivity, is practically not conceivable with the "forms" known at present because these are not currently equipped only with a fairly rudimentary gripping means and in any case unsuited to the requirements of precision necessary to allow an implementation of automation by robotics.

Il importe en effet que la tige de la chaussure occupe toujours une position rigoureusement déterminée par rapport au bras du robot, et ceci dans trois directions : longitudinale, transversale et verticale. Une forme habituelle comporte dans sa partie arrière supérieure un méplat dans la partie centrale duquel est prévu un trou borgne pour le montage de la forme sur un béquillon permettant de supporter la forme et la chaussure à l'état renversé pour certaines opérations de fabrication de la chaussure. Il est bien évident qu'un tel dispositif de préhension ne permet pas une précision suffisante pour permettre une automatisation par robotique.It is indeed important that the upper of the shoe always occupies a strictly determined position relative to the arm of the robot, and this in three directions: longitudinal, transverse and vertical. A usual form has in its upper rear part a flat in the central part of which is provided a blind hole for mounting the form on a crutch for supporting the form and the shoe in the inverted state for certain operations of manufacturing the shoe. It is obvious that such a gripping device does not allow sufficient precision to allow automation by robotics.

L'invention a pour objet une "forme" pour la fabrication de chaussures dont l'agencement permet sa manipulation au moyen d'un bras robot. Elle est caractérisée en ce que sa partie arrière supérieure est surmontée d'une tête de préhension, ladite tête comportant au moins deux organes d'accrochage, du genre crans ou protubérances, aménagés respectivement dans sa face avant et dans sa face arrière et de formes telles qu'il permettent à un organe préhenseur comportant des mâchoires de forme complémentaire de saisir la forme en la maintenant dans une position rigoureusement déterminée.The subject of the invention is a "form" for the manufacture of shoes, the arrangement of which allows its manipulation by means of a robot arm. It is characterized in that its upper rear part is surmounted by a gripping head, said head comprising at least two hooking members, of the notch or protuberance type, arranged respectively in its front face and in its rear face and of shapes such as to allow a gripping member having jaws of complementary shape to grasp the shape by keeping it in a strictly determined position.

Avantageusement par ailleurs, ladite tête de préhension comporte un méplat latéral recevant des indications, du genre code ou graduation, destinées à être lues par le robot au moment de la préhension.Advantageously also, said gripping head comprises a lateral flat receiving indications, of the code or graduation type, intended to be read by the robot at the time of gripping.

Avantageusement enfin, ladite tête de préhension comporte en outre au moins un organe de positionnement du genre cran ou protubérance, aménagé dans sa face arrière et permettant à la forme, munie ou non de la chaussure, de reposer en appui, dans une position rigoureusement déterminée, sur un ratelier de stockage.Advantageously finally, said gripping head further comprises at least one positioning member of the notch or protuberance type, arranged in its rear face and allowing the shape, whether or not provided with the shoe, to rest in support, in a strictly determined position , on a storage rack.

L'invention sera mieux comprise, et d'autres caractéristiques apparaîtront au cours de la description suivante d'un exemple préférentiel de réalisation, en référence aux dessins schématiques annexés dans lesquels:

  • Figure 1 est une vue en perspective éclatée de la forme de l'invention en place dans une chaussure ;
  • Figure 2 est une vue en coupe longitudinale partielle de la forme de l'invention en place dans une chaussure ;
  • Figure 3 représente schématiquement la forme de l'invention équipée d'une chaussure et en position de stockage sur un ratelier, avec le bras de préhension du robot en cours de retrait.
The invention will be better understood, and other characteristics will appear during the following description of a preferred embodiment, with reference to the appended schematic drawings in which:
  • Figure 1 is an exploded perspective view of the form of the invention in place in a shoe;
  • Figure 2 is a partial longitudinal sectional view of the form of the invention in place in a shoe;
  • Figure 3 schematically shows the form of the invention equipped with a shoe and in the storage position on a rack, with the gripping arm of the robot being removed.

En se reportant à l'ensemble des figures 1 et 2, la forme de l'invention, désignée généralement par la référence 1 et représentée sur l a figure 1 en place dans une chaussure 2 en cours de fabrication, se différencie des formes de l'art antérieur par le fait que sa partie arrière supérieure 3, ou zone de talon, est surmontée d'une tête de préhension 4, de relativement importantes dimensions tel que représenté sur les dessins, cette tête 4 présentant :
-deux protubérances 8,9 de forme anguleuse à facettes et biseautée comme représenté, aménagées respectivement sur la face arrière et sur la face avant de la tête 4, grâce auxquelles le bras du robot, équipé d'une pince de préhension de forme complémentaire, peut saisir la forme 1 en la maintenant dans une position rigoureusement déterminée,
-un méplat latéral 5 dirigé perpendiculairement par rapport au plan général de la semelle 6, et recevant une graduation codée 7, qui permet au robot, lorsqu'il saisit la tête de préhension 4 de la forme 1, de lire la pointure, la configuration, le type de cette forme et le caractère droit ou gauche de la chaussure, et ainsi de choisir et de déclencher un programme grâce auquel chacune des machines, à laquelle la chaussure sera présentée par le bras du robot, effectuera l'opération qui lui est propre, en tenant compte des caractéristiques de la forme concernée ; dans l'exemple de réalisation considéré, la graduation codée 7 est un code-barres porté sur une plaquette amovible 30 retenue contre le méplat 5 dans une glissière 31 ; les plaquettes 30 sont ainsi aisément interchangeables,
-un cran 10 aménagé sur la face arrière de la tête 4, en dessous de la protubérance 8, ayant une forme anguleuse générale en queue d'aronde, grâce auquel la forme 1, munie ou non de la chaussure, peut reposer en appui dans une position rigoureusement déterminée sur un ratelier de stockage, comme on le voit sur la figure 3 qui sera décrite ci-après,
-une nervure centrale longitudinale inférieure 11 destinée à la mise en place de la tête 4 sur la partie arrière supérieure 3 (zone de talon) de la forme 1 ; à cet effet, la face supérieure 12 de la forme dans sa zone arrière est rectifiée de manière a être plane, et dans cette zone plane 12 est aménagée une rainure longitudinale 13 qui se termine par un rebord avant vertical 15 et qui coopére étroitement avec la nervure 11 de la tête 4, cette dernière venant en butée, par sa face avant, contre le rebord 15.Referring to all of Figures 1 and 2, the shape of the invention, generally designated by the reference 1 and shown in Figure 1 in place in a shoe 2 during manufacture, differs from the shapes of the prior art by the fact that its upper rear part 3, or heel zone, is surmounted by a gripping head 4, of relatively large dimensions as shown in the drawings, this head 4 having:
two protrusions 8.9 of angular shape with facets and bevelled as shown, arranged respectively on the rear face and on the front face of the head 4, thanks to which the robot arm, equipped with a gripper of complementary shape, can grasp form 1 by keeping it in a rigorously determined position,
-a lateral flat 5 directed perpendicularly to the general plane of the sole 6, and receiving a coded graduation 7, which allows the robot, when it grasps the gripping head 4 of the shape 1, to read the size, the configuration , the type of this form and the right or left character of the shoe, and thus of choosing and triggering a program by which each of the machines, to which the shoe will be presented by the arm of the robot, will carry out the operation which is specific to it, taking account of the characteristics of the shape concerned; in the embodiment considered, the coded graduation 7 is a bar code carried on a removable plate 30 retained against the flat 5 in a slide 31; the plates 30 are thus easily interchangeable,
a notch 10 arranged on the rear face of the head 4, below the protuberance 8, having a general angular shape in dovetail, thanks to which the shape 1, whether or not provided with the shoe, can rest in support in a rigorously determined position on a storage rack, as can be seen in FIG. 3 which will be described below,
a lower longitudinal central rib 11 intended for the positioning of the head 4 on the upper rear part 3 (heel area) of the shape 1; for this purpose, the upper face 12 of the form in its rear zone is rectified so as to be plane, and in this plane zone 12 is provided a longitudinal groove 13 which ends in a vertical front edge 15 and which cooperates closely with the rib 11 of head 4, the latter coming into abutment, by its front face, against flange 15.

Par ailleurs, la partie supérieure de la tête 4 est percée d'un orifice borgne 32, perpendiculaire à la semelle 6, de sorte que la forme 1 est aussi utilisable sur les machines traditionnelles.Furthermore, the upper part of the head 4 is pierced with a blind hole 32, perpendicular to the sole 6, so that the shape 1 is also usable on traditional machines.

Comme on le voit sur la figure 2, la tête 4 après sa mise en place sur la zone de talon 3, est solidarisée à celle-ci par le moyen de deux vis 16 introduites dans la forme 1 à partir de la face inférieure de celle-ci grâce à deux trous à épaulement 17 percés dans celle-ci.As can be seen in FIG. 2, the head 4 after being placed on the heel area 3, is secured to it by means of two screws 16 introduced in the form 1 from the underside of that -this thanks to two shoulder holes 17 drilled therein.

En se reportant maintenant à la figure 3, la forme 1 de l'invention munie de sa chaussure 2 est en appui, dans une position rigoureusement déterminée, sur un ratelier de stockage 18 essentiellement équipé d'une barre d'appui avant 19, de section uniforme, sur laquelle vient s'appuyer comme représenté la partie avant inférieure de la forme ou de la semelle, et d'une barre arrière 20 d'appui et de positionnement précis de la tête 4 de la forme grâce à des encoches 21 pratiquées sur cette borne 20 de manière complémentaire du cran arrière inférieur 10 de chaque forme 1, chaque cran anguleux 10 venant donc s'encastrer étroitement dans l'encoche 21 correspondante.Referring now to FIG. 3, the form 1 of the invention provided with its shoe 2 is supported, in a rigorously determined position, on a storage rack 18 essentially equipped with a front support bar 19, of uniform section, on which rests as shown the lower front part of the shape or sole, and a rear bar 20 for support and precise positioning of the head 4 of the shape thanks to notches 21 made on this terminal 20 in a complementary manner to the lower rear notch 10 of each shape 1, each angular notch 10 therefore coming to fit closely into the corresponding notch 21.

On suppose sur la figure 3, à titre d'exemple, que la forme 1 vient d'être reposée, munie d'une chaussure 2 totalement ou partiellement terminée, sur le ratelier de stockage 18 par un bras-robot 22.It is assumed in FIG. 3, by way of example, that the form 1 has just been rested, provided with a shoe 2 totally or partially finished, on the storage rack 18 by a robot arm 22.

Le bras-robot 22 est équipé d'une tête de préhension 23 comportant une pince 24 dont une des mâchoires 25 est fixe en position sur la tête 23 et a une forme rigoureusement complémentaire à la protubérance arrière 8 de la tête 4 de la forme 1, et dont l'autre mâchoire 26, de fome rigoureusement complémentaire à la protu bérance avant 9 de la tête 4, est portée par la tige 27 d'un vérin 28 fixé sur la tête de robot 23 comme représenté sur le dessin.The robot arm 22 is equipped with a gripping head 23 comprising a clamp 24, one of the jaws 25 of which is fixed in position on the head 23 and has a shape strictly complementary to the rear protuberance 8 of the head 4 of the shape 1 , and the other jaw 26 of which is rigorously complementary to the front protuberance 9 of the head 4, is carried by the rod 27 of a jack 28 fixed on the robot head 23 as shown in the drawing.

Par action du vérin 28 et du bras robot 22, la pince 24 peut donc venir saisir la tête 4 de la forme 1 par les protubérances 8 et 9 de manière rigoureusement précise en positions relatives, lesdites protubérances 8,9 venant s'encastrer rigoureusement dans les mâchoires complémentaires 25,26 de la pince 24.By the action of the jack 28 and of the robot arm 22, the clamp 24 can therefore come to grip the head 4 of the shape 1 by the protuberances 8 and 9 in a strictly precise manner in relative positions, said protuberances 8,9 coming to fit rigorously into the complementary jaws 25, 26 of the clamp 24.

Enfin, la tête de préhension 23 du robot comporte un organe de lecture 29 des graduations codées 7 portées sur le méplat 5 de la tête 4 de la forme 1. Dans l'exemple considéré, cet organe de lecture comporte huit capteurs de proximité, non apparents sur le dessin, détectant la présence ou l'absence d'un pion dans le trou taraudé 70 correspondant.Finally, the gripping head 23 of the robot comprises a member 29 for reading the coded graduations 7 carried on the flat 5 of the head 4 of the shape 1. In the example considered, this reading member comprises eight proximity sensors, not apparent in the drawing, detecting the presence or absence of a pin in the corresponding tapped hole 70.

L'invention n'est évidemment pas limitée à l'exemple de réalisation qui vient d'être décrit. La tête 4 pourrait être équipée de crans en forme de queue d'aronde par exemple au lieu des protubérances 8,9, et inversement d'une protubérance à la place du cran 10. Les formes de ces protubérances ou crans à caractère anguleux pourraient être remplacées par des formes en portion de cercle. Enfin, au lieu d'être constituée par une forme classique usinée de manière à y rapporter une tête conforme à l'invention, l'ensemble corps et tête de l'invention peut avantageusement être réalisé d'un seul bloc par moulage en matière plastique ou en alliage métallique léger par exemple. The invention is obviously not limited to the embodiment which has just been described. The head 4 could be equipped with notches in the form of a dovetail, for example instead of the protrusions 8, 9 and conversely with a protuberance in place of the notch 10. The shapes of these protrusions or notches of angular nature could be replaced by shapes in a circle portion. Finally, instead of being constituted by a conventional shape machined so as to attach a head to it according to the invention, the body and head assembly of the invention can advantageously be made in one piece by plastic molding. or in light metal alloy for example.
