Description

L'invention concerne un nouveau type de boucle utilisée en maroquinerie, sellerie ou prêt-à-porter, ainsi qu'une machine automatique pour l'acheminement contrôlé et la fixation, notam­ment par rivetage, de cette boucle sur un support-cuir (naturel ou synthétique) ou sur une pièce de tissu.The invention relates to a new type of loop used in leather goods, saddlery or ready-to-wear, as well as an automatic machine for the controlled routing and fixing, in particular by riveting, of this loop on a leather support (natural or synthetic) or on a piece of fabric.

Les boucles utilisées jusqu'alors sur des pièces de cuir, et en particulier dans le domaine de la chaussure, sont cons­tituées de façon classique d'un anneau fermé divisé en deux parties, symétriques ou non, par un axe ou barrette sur lequel sont montés arti­culés l'ardillon et la pièce qui sert à la fixation de la boucle sur son support dénommée ici "chape". La fixation de ces boucles sur leur support tissu ou cuir s'effectue alors manuellement, en particulier par rivetage lorsque l'on travaille le cuir. Cette opération, qui est laissée à la dextérité de l'opérateur, entraîne de multiples manipula­tions qui grèvent le coût de fabrication et génèrent des risques d'accident, en particulier lors de la descente du poinçon assurant l'opération de rivetage.The buckles used until then on pieces of leather, and in particular in the field of footwear, consist in a conventional manner of a closed ring divided into two parts, symmetrical or not, by an axis or bar on which are mounted. articulated the barb and the part which is used for fixing the buckle on its support here called "clevis". The fixing of these loops on their fabric or leather support is then carried out manually, in particular by riveting when working the leather. This operation, which is left to the dexterity of the operator, leads to multiple manipulations which increase the manufacturing cost and generate risk of accident, in particular during the descent of the punch ensuring the riveting operation.

Il n'avait pas été possible jusqu'alors d'envisager la pose automatique des boucles à l'aide d'une machine travaillant en cycle continu en raison du fait qu'une telle automatisation nécessitait un contrôle de l'orientation des boucles,au cours de leur acheminement au poste de rivetage, afin de s'assurer que celles-ci soient toujours orientées dans le même sens. En effet, dans le cas de boucles de type asymétrique, il est indispensable de s'assurer que l'anneau est toujours dirigé dans le même sens, afin d'éviter qu'elles soient fixées dans le mauvais sens.It had not been possible until then to envisage the automatic laying of the loops using a machine working in continuous cycle due to the fact that such automation required a control of the orientation of the loops, at the during their routing to the riveting station, to ensure that they are always oriented in the same direction. Indeed, in the case of asymmetrical type loops, it is essential to ensure that the ring is always directed in the same direction, in order to avoid that they are fixed in the wrong direction.

Cette difficulté a été résolue en dotant les boucles d'un repère susceptible d'être lu par un dispositif de contrôle équipant la machine automatique de pose des boucles. Ainsi pourvues de ce repère, on peut désormais s'assurer que les boucles sont bien orientées dans le même sens au cours de leur acheminement et qu'elles seront, par consé­quent, correctement fixées sur leur support lors de l'opération de ri­vetage. C'est donc ce repère qui a permis de mettre au point une ma­chine automatique permettant d'acheminer les boucles depuis une capacité de stockage à un poste de rivetage sans pratiquement aucune intervention manuelle.This difficulty has been resolved by providing the loops with a marker capable of being read by a control device fitted to the automatic loop fitting machine. Thus provided with this reference, we can now ensure that the loops are oriented in the same direction during their routing and that they will, therefore, be correctly fixed on their support during the riveting operation. It is therefore this benchmark which has made it possible to develop an automatic machine making it possible to route the loops from a storage capacity to a riveting station without practically any manual intervention.

L'invention concerne donc une boucle utilisée en maroquinerie, sellerie ou prêt-à-porter, du type constitué d'un anneau séparé,symétriquement ou non,par un axe sur lequel pivotent l'ardillon et la chape servant à la fixation de ladite boucle sur son support textile ou cuir cette boucle étant caractérisée en ce qu'elle comporte au moins un repère susceptible d'être lu par un dispositif contrôlant l'orientation de la boucle dans une machine automatique pour la pose et la fixation desdites boucles.The invention therefore relates to a loop used in leather goods, saddlery or ready-to-wear, of the type consisting of a separate ring, symmetrically or not, by an axis on which pivot the barb and the yoke used for fixing said said loop on its textile or leather support, this loop being characterized in that it comprises at least one mark capable of being read by a device controlling the orientation of the loop in an automatic machine for fitting and fixing said loops.

Selon un mode de réalisation préférentiel, le repère est constitué soit par la forme asymétrique de la chape elle-même, soit par un orifice ménagé dans cette chape ou par une encoche, une cavité, un évidement, un bossage ou encore une pastille de couleur apposée sur la chape.According to a preferred embodiment, the reference point is constituted either by the asymmetrical shape of the yoke itself, or by an orifice made in this yoke or by a notch, a cavity, a recess, a boss or even a colored patch affixed to the yoke.

L'invention s'étend également à une machine automa­tique pour la fixation de telles boucles, caractérisée en ce qu'elle est constituée d'une capacité de stockage vibrante, dotée de moyens d'entraî­nement et de sélection des boucles, d'une rampe de distribution achemi­nant les boucles depuis la capacité de stockage à un poste de transfert, cette rampe comportant, d'une part, un dispositif de lecture du repère porté par la boucle pour contrôler son orientation et décider éventuel­lement de son éviction, d'autre part, un sélecteur pour la distribution individuelle des boucles au poste de transfert, lequel poste comporte des moyens de préhension mobiles saisissant la boucle pour la déposer sur la matrice du dispositif de rivetage.The invention also extends to an automatic machine for fixing such loops, characterized in that it consists of a vibrating storage capacity, provided with means for driving and selecting the loops, with a ramp distribution channeling the loops from the storage capacity to a transfer station, this ramp comprising, on the one hand, a device for reading the mark carried by the loop to control its orientation and possibly decide on its eviction, on the other hand , a selector for the individual distribution of the loops at the transfer station, which station includes movable gripping means gripping the loop to deposit it on the matrix of the riveting device.

Selon une caractéristique de l'invention, la rampe de distribution est formée d'une glissière inclinée dans laquelle glisse la chape de la boucle, l'anneau proprement dit glissant sur les deux bords externes de cette glissière.According to a characteristic of the invention, the distribution ramp is formed of an inclined slide in which the clevis of the loop slides, the ring proper sliding on the two outer edges of this slide.

Selon un mode de réalisation préférentiel, le dis­positif détecteur de l'orientation des boucles est constitué d'une cel­lule photo-électrique dont le rayon est situé en regard d'un perçage traversant la glissière et coïncidant avec le repère de la chape de la boucle, en l'occurence un orifice circulaire excentré.According to a preferred embodiment, the device for detecting the orientation of the loops consists of a photoelectric cell, the radius of which is located opposite a hole passing through the slide and coinciding with the mark of the clevis of the loop. , in this case an eccentric circular orifice.

La machine automatique pour la pose des boucles se­lon l'invention est constituée essentiellement de quatre postes, à sa­voir une capacité de stockage des boucles ou bol vibreur 1, une rampe de distribution 2 assurant l'acheminement des boucles depuis le bol vibreur à une unité de rivetage 3 et, enfin, un poste d'évacuation des pièces de tissu ou cuir pourvues des boucles, après l'opération de fixation.The automatic machine for placing the loops according to the invention essentially consists of four stations, namely a storage capacity for the loops or vibrating bowl 1, a distribution ramp 2 ensuring the routing of the loops from the vibrating bowl to a unit riveting 3 and, finally, a station for removing pieces of fabric or leather provided with the loops, after the fixing operation.

La capacité de stockage des boucles est constituée ici d'une sorte de bol circulaire dans lequel sont déversées en vrac les boucles devant être acheminées au poste ou unité de rivetage, cette capacité présentant la particularité de comporter une sorte de rampe spiralée 4 s'identifiant à une vis sans fin et permettant un entraîne­ment progressif et ascensionnel des boucles,depuis le fond du bol 1 jusqu'a son bord supérieur 1₁,contigu à la rampe de distribution 2. Cet entraînement spiralé et sélectif des boucles est obtenu par des vibreurs fixés de façon classique sur le châssis 5 supportant la capacité de stoc­kage.The storage capacity of the loops here consists of a sort of circular bowl into which the loops are poured in bulk, to be routed to the station or riveting unit, this capacity having the particularity of comprising a sort of spiral ramp 4 identified to a worm and allowing a progressive and upward drive of the loops, from the bottom of the bowl 1 to its upper edge 1₁, contiguous to the distribution ramp 2. This spiral and selective drive of the loops is obtained by fixed vibrators conventionally on the chassis 5 supporting the storage capacity.

Lorsque les boucles arrivent au niveau du bord supé­rieur 1₁ du bol, elles sont transférées automatiquement dans la rampe de distribution 2 qui est réalisée sous la forme d'une glissière inclinée. Comme visible en section sur la figure 2, cette glissière se présente sous la forme d'un rail pourvu d'une rainure longitudinale 6 débouchant sur la face supérieure 2₁ de la glissière, les bords de cette rainure 6 étant tronqués et légèrement incurvés pour former un siège 6₁ destiné à recevoir le noeud d'articulation 7 de la chape 8 de la boucle 9. Cette boucle est en effet constituée de façon classique d'un anneau fermé 9 divisé en deux parties, symétriques ou non, par un axe ou barrette 10 sur lequel est monté librement pivotant l'ardillon 11 et la chape 8.When the loops arrive at the upper edge 1₁ of the bowl, they are automatically transferred to the distribution ramp 2 which is produced in the form of an inclined slide. As visible in section in FIG. 2, this slide is in the form of a rail provided with a longitudinal groove 6 opening onto the upper face 2₁ of the slide, the edges of this groove 6 being truncated and slightly curved to form a seat 6₁ intended to receive the articulation node 7 of the yoke 8 of the loop 9. This loop is in fact conventionally constituted by a closed ring 9 divided into two parts, symmetrical or not, by an axis or bar 10 on which is freely mounted pivoting the barb 11 and the yoke 8.

Selon l'invention, cette chape 8, qui comporte de façon classique un orifice 12 destiné à sa fixation sur le support cuir ou tissu, présente la particularité de comporter un repère visuel sus­ ceptible d'être lu par un dispositif de contrôle permettant de déceler les boucles circulant dans la glissière, c'est-à-dire dans la rainure 6, qui seraient mal orientées. Il est en effet indispensable, en particu­lier lorsqu'il s'agit de boucles de type asymétrique, que celles-ci se présentent dans la rainure 6 toujours dans le même sens afin d'éviter des fixations inversées sur la pièce de cuir ou de tissu. Le repère pré­vu sur la chape a donc pour effet de permettre au dispositif de lecture de vérifier l'orientation de la boucle et, éventuellement, de l'écarter du circuit par une trappe d'éjection 13, telle que visible en figure 1.According to the invention, this yoke 8, which conventionally comprises an orifice 12 intended for its attachment to the leather or fabric support, has the particularity of comprising a visual cue sus capable of being read by a control device making it possible to detect the loops circulating in the slide, that is to say in the groove 6, which would be badly oriented. It is indeed essential, in particular in the case of asymmetrical type loops, that these appear in the groove 6 always in the same direction in order to avoid reverse fastenings on the piece of leather or fabric . The mark provided on the yoke therefore has the effect of allowing the reading device to check the orientation of the loop and, possibly, to remove it from the circuit by an ejection hatch 13, as visible in FIG. 1.

Le repère prévu sur la boucle, notamment sur la chape 8, peut résulter,soit de la forme asymétrique de la chape propre­ment dite comme schématisé en 8₁ sur la figure 3, soit de tout autre signe visuel tel qu'une encoche, une cavité, un évidement, un bossage, voire encore une pastille de couleur figurant sur la chape. Dans l'exemple considéré, le repère est constitué par un orifice 14 traver­sant la chape de part en part et permettant ainsi le passage d'un rayon lumineux 15 (figure 2), d'une cellule photo-électrique comportant de façon classique un émetteur 16 et un récepteur 17. Dans cet esprit, la glissière 2 est évidemment pourvue d'un perçage transversal 18 traver­sant de part en part la rampe de distribution et permettant ainsi le passage du rayon lumineux 15.The mark provided on the loop, in particular on the yoke 8, can result either from the asymmetrical shape of the yoke itself as shown diagrammatically in 8₁ in FIG. 3, or from any other visual sign such as a notch, a cavity, a recess, a boss, or even a colored patch on the screed. In the example considered, the reference point is constituted by an orifice 14 passing through the yoke from end to end and thus allowing the passage of a light ray 15 (FIG. 2), of a photoelectric cell comprising in a conventional manner a transmitter. 16 and a receiver 17. In this spirit, the slide 2 is obviously provided with a transverse bore 18 passing right through the distribution ramp and thus allowing the passage of the light ray 15.

Le contrôle de l'orientation des boucles s'effectue sensiblement au niveau de la ligne de coupe A-A de la figure 1. A ce stade, la chape 8 de la boucle est immobilisée temporairement dans la rainure 6 de la glissière par un vérin d'arrêt 19, venant en butée sur le bord latéral de la chape, comme visible en figure 3. Etant donné que l'orifice 14,constituant le repère pour le contrôle de l'orientation de la boucle, est excentré par rapport à l'axe médian 20 passant par le centre de l'orifice de fixation 12 de la chape, il est clair que,si la boucle est en position retournée, le faisceau lumineux 15 ne pourra pas passer de l'émetteur au récepteur puisqu'il sera interrompu par la chape 8 qui fera écran. Ce n'est que si la boucle est correctement orientée que le faisceau lumineux pourra traverser de part en part l'ensemble de la glissière 2 et ainsi commander le transfert de la boucle vers le poste de rivetage. En d'autres termes, le faisceau lumineux de la cellu­le photo-électrique est rigoureusement positionné dans le plan excentré de l'orifice de contrôle 14 prévu sur les chapes de boucle.The orientation of the loops is checked substantially at the level of the cutting line AA in FIG. 1. At this stage, the yoke 8 of the loop is temporarily immobilized in the groove 6 of the slide by a jack. stop 19, abutting on the lateral edge of the yoke, as visible in FIG. 3. Since the orifice 14, constituting the mark for controlling the orientation of the loop, is eccentric relative to the axis median 20 passing through the center of the fixing hole 12 of the yoke, it is clear that, if the loop is in the inverted position, the light beam 15 will not be able to pass from the transmitter to the receiver since it will be interrupted by the screed 8 which will screen. It is only if the loop is correctly oriented that the light beam can pass right through the whole of the slide 2 and thus control the transfer of the loop to the riveting station. In other words, the light beam of the photoelectric cell is rigorously positioned in the eccentric plane of the control orifice 14 provided on the loop yokes.

Lorsque le contrôle de positionnement de la boucle a été effectué, celle-ci est dirigée vers un sélecteur 21 qui assure la distribution individuelle des boucles au dispositif de préhension 22 alimentant le poste de rivetage 3. Dans l'exemple considéré, ce sélec­teur en soi connu est constitué d'un simple balancier retenant les bou­cles stockées dans la glissière et n'autorisant leur distribution que une à une afin d'éviter l'engorgement du dispositif de préhension 22.When the loop positioning control has been carried out, it is directed to a selector 21 which ensures the individual distribution of the loops to the gripping device 22 supplying the riveting station 3. In the example considered, this selector per se known is constituted by a simple pendulum retaining the loops stored in the slide and authorizing their distribution only one by one in order to avoid clogging of the gripping device 22.

Ce dispositif de préhension est constitué d'une pince montée rotative et télescopique de manière à pouvoir saisir la boucle dans la glissière 6, puis, à l'aide d'un bras manipulateur 23, mobile en translation alternative, amener la chape de cette boucle sur la matrice 24 de l'unité de rivetage illustrée en figure 4. On observe ici que la chape 8 de la boucle 9 a effectivement été enfichée sur la partie ré­trécie de la matrice de rivetage 24 par le jeu de son orifice de fixa­tion 12. A ce stade, on dispose alors la pièce de cuir de tissu 25, préalablement perforée, sur l'extrémité de la matrice 24 afin de procé­der à l'opération de rivetage proprement dite.This gripping device consists of a clamp mounted rotatable and telescopic so as to be able to grasp the loop in the slide 6, then, using a manipulator arm 23, movable in alternative translation, bring the yoke of this loop on the die 24 of the riveting unit illustrated in FIG. 4. It is observed here that the yoke 8 of the loop 9 has actually been inserted on the narrowed part of the riveting die 24 by the play of its fixing orifice 12. At this stage, the piece of fabric leather 25, previously perforated, is then placed on the end of the matrix 24 in order to carry out the actual riveting operation.

Le poste de rivetage est constitué de façon classi­que d'un dispositif comprenant un magasin de rivet 26 délivrant les rivets un à un à un poinçon 27 monté mobile en translation alternative verticale et assurant l'opération de matriçage du rivet. Cette opéra­tion est favorisée par un viseur optique 28 servant à positionner le morceau de cuir ou de tissu dans la pince de manutention 30 portée par le bras de transfert 29 et celle-ci,après déclanchement,vient position­ner le cuir ou le tissu sur la matrice 24.The riveting station conventionally consists of a device comprising a rivet magazine 26 delivering the rivets one by one to a punch 27 mounted movable in vertical alternative translation and ensuring the operation of stamping the rivet. This operation is favored by an optical viewfinder 28 used to position the piece of leather or fabric in the handling clamp 30 carried by the transfer arm 29 and the latter, after triggering, comes to position the leather or the fabric on the matrix 24.

Après l'operation de rivetage, ce bras de transfert 29, monté mobile angulairement dans un plan horizontal (figure 5) par le jeu du vérin rotatif 31, entraîne la pièce de cuir munie de sa boucle, du poste de matriçage à une goulotte d'évacuation inclinée 32 qui déverse les articles dans un bac de récupération 33. Bien entendu, le bras de transfert 29 est également animé d'une faible course verticale de ma­nière à pouvoir enficher les pièces de tissu ou de cuir sur la matrice 24 et en effectuer ensuite le dégagement et le retrait.After the riveting operation, this transfer arm 29, mounted angularly movable in a horizontal plane (Figure 5) by the play of the rotary actuator 31, drives the piece of leather provided with its loop, from the stamping station to a chute d inclined discharge 32 which pours the articles into a collecting tank 33. Of course, the transfer arm 29 is also driven by a short vertical stroke so as to be able to plug the pieces of fabric or leather onto the matrix 24 and in then perform the release and removal.

Ainsi, l'essentiel de l'invention réside dans le fait que la boucle, et plus particulièrement sa chape, comportent un repère d'identification de son orientation dans une machine de pose automati­que, ce repère coopérant avec un dispositif de lecture prévu sur la rampe de distribution, celle-ci fonctionnant en étroite corrélation avec un bol vibreur permettant d'acheminer les boucles une à une depuis la capacité de stockage à la glissière inclinée 2 conduisant au poste de rivetage. Par contre, le poste de rivetage proprement dit est de type classique, si ce n'est qu'il lui a été associé un vérin et un viseur optique pour contrôler la descente du poinçon et éviter tout accident de manipulation.Thus, the essence of the invention resides in the fact that the loop, and more particularly its yoke, comprise a mark identifying its orientation in an automatic laying machine, this mark cooperating with a reading device provided on the distribution ramp, this one operating in close correlation with a vibrating bowl making it possible to route the loops one by one from the storage capacity at the inclined slide 2 leading to the riveting station. On the other hand, the actual riveting station is of the conventional type, except that it has been associated with a jack and an optical sight to control the descent of the punch and avoid any handling accident.
