Description

L'invention concerne une sertisseuse automatique d'attaches de cadre à partir d'un ruban portant des attaches accolées.An automatic crimping machine for frame fasteners from a tape with attached fasteners.

Pour la pose individuelle d'attaches de dos de cadre, on connaît des sertisseuses pneumatiques dont la tête de sertissage mue par un vérin permet d'exercer une pression sur l'attache positionnée en aveugle sur ladite tête, pour l'appliquer sur le dos du cadre, lui-même en appui sur une platine-support (voir par exemple EP-A-0 899 054).For the individual installation of frame back fasteners, pneumatic crimping machines are known whose crimping head moved by a jack makes it possible to exert pressure on the fastener positioned blindly on said head, to apply it on the back. frame, itself supported on a support plate (see for example EP-A-0 899 054).

On connaît également une autre forme de sertisseuse pneumatique telle que décrite dans la demande de brevet français n° 99 16717 au nom de la Demanderesse, dans laquelle l'attache est positionnée, non pas sur la tête de sertissage, mais sur une enclume profilée localisée sur une platine support. La tête de sertissage est alors montée de façon à pouvoir être dégagée de la zone de positionnement de l'attache sur la platine support, sous l'action d'un mécanisme de manoeuvre, cela afin d'accéder aisément à l'enclume profilée. Bien entendu un capot protecteur s'abaisse autour de l'enclume, lors de l'opération d'agrafage, pour éviter tout accident.Another form of pneumatic crimping machine is also known, as described in the French patent application No. 99 16717 in the name of the Applicant, in which the fastener is positioned, not on the crimping head, but on a localized profiled anvil. on a support plate. The crimping head is then mounted so as to be disengaged from the positioning zone of the fastener on the support plate, under the action of an operating mechanism, in order to easily access the profiled anvil. Of course a protective cover is lowered around the anvil, during the stapling operation, to avoid any accident.

Cette machine fonctionne donc au coup par coup et nécessite une manipulation de l'opérateur pour la mise en place de chaque attache et le retrait de chaque carton agrafé.This machine therefore works piecemeal and requires manipulation of the operator for the establishment of each fastener and the withdrawal of each stapled cardboard.

Afin d'améliorer la rapidité de la pose de ces attaches, la Daranderesse a mis au point une sertisseuse automatique fonctionnant à partir d'un ruban d'attaches accolées les unes à côté des autres, le ruban se déroulant pas à pas vers le poste où les attaches sont séparées, au fur et à mesure, de l'attache voisine, puis serties par la tête de sertissage.To improve the speed of the installation of these fasteners, the Dancer has developed an automatic crimper working from a tape of fasteners next to each other, the tape taking place step by step to the post where the fasteners are separated, as and when the neighboring fastener, then crimped by the crimping head.

Un objet principal de la présente invention consiste donc en une sertisseuse automatique d'attaches de cadre à partir d'un ruban d'attaches accolées, comportant une tête de sertissage à mouvement vertical, commandée par vérin, pour l'enfoncement dans un carton d'une attache positionnée par rapport à une enclume profilée localisée sur une platine-support, sertisseuse selon laquelle ladite enclume profilée est une enclume de sertissage et de découpe déplaçable entre une position basse où elle s'efface au-dessous du niveau de la platine-support, et une position haute où elle déborde au-dessus de ladite platine, un couteau dont la partie centrale forme un pont étant fixé à la platine, au contact de l'enclume.A main object of the present invention is therefore an automatic crimping machine of frame fasteners from a tape of contiguous fasteners, having a jack-up vertical movement crimping head for insertion into a carton of fasteners. 'a fastener positioned relative to a profiled anvil located on a support plate, crimper according to which said profiled anvil is a crimping and cutting anvil movable between a low position where it disappears below the level of the support plate, and a high position where it overflows above said plate, a knife whose central portion forms a bridge being fixed to the plate in contact with the anvil.

D'autres caractéristiques particulières de l'invention ressortiront de la description qui va suivre d'un exemple de réalisation dans lequel il est fait référence aux dessins annexés qui représentent :

  • Figure 1 une vue générale en perspective de la sertisseuse automatique.
  • Figure 2 une vue en perspective à plus grande échelle de la platine support avec l'enclume en position haute.
  • Figure 3 une vue analogue à celle de la figure 2 avec l'enclume en position basse.
  • Figure 4 une vue analogue à celle de la figure 3 montrant l'introduction d'un ruban d'attaches sur la platine.
  • Figure 5 une vue analogue à celle de la figure 4 montrant l'enclume en position haute, portant une attache.
Other particular features of the invention will emerge from the following description of an exemplary embodiment in which reference is made to the appended drawings which represent:
  • Figure 1 a general perspective view of the automatic crimper.
  • Figure 2 a perspective view on a larger scale of the support plate with the anvil in the high position.
  • Figure 3 a view similar to that of Figure 2 with the anvil in the low position.
  • Figure 4 a view similar to that of Figure 3 showing the introduction of a tape fasteners on the plate.
  • Figure 5 a view similar to that of Figure 4 showing the anvil in the raised position, carrying a clip.

La sertisseuse montrée à la figure 1 comporte essentiellement une platine support 1 pour le positionnement du carton et de l'attache sur une enclume de sertissage et de découpe 6 dont est munie la platine, une tête de sertissage 2 pour l'enfoncement de l'attache et des mécanismes de manoeuvre de la tête.The crimping machine shown in FIG. 1 essentially comprises a support plate 1 for positioning the cardboard and the fastener on a crimping and cutting anvil 6 of which the plate is provided, a crimping head 2 for the insertion of the crimping tool. fastener and mechanisms for maneuvering the head.

La tête 2 qui se développe verticalement dans la sertisseuse, au dessus de la table, est articulée en partie haute autour d'un axe horizontal 4. Elle peut pivoter ainsi, sous l'action d'un petit vérin 5, entre deux positions : une première position verticale dans laquelle l'extrémité de la tête est à l'aplomb de l'attache et une seconde position inclinée où la tête est basculée vers l'arrière de la machine et libère ainsi la zone de positionnement de l'attache.The head 2 which develops vertically in the crimper, above the table, is articulated in the upper part about a horizontal axis 4. It can pivot thus, under the action of a small cylinder 5, between two positions: a first vertical position in which the end of the head is in line with the fastener and a second inclined position where the head is tilted towards the rear of the machine and thus releases the positioning zone of the fastener.

La platine dispose aussi de réglettes de guidage 15 facilitant la mise en place correcte du carton, entre lesquelles se trouve l'enclume 6. Un capot protecteur 3 est monté sur des bras 7 pivotants autour d'un axe horizontal 9.The plate also has guiding strips 15 facilitating the correct placement of the carton, between which is the anvil 6. A protective cover 3 is mounted on arms 7 pivoting about a horizontal axis 9.

La tête de sertissage 2 est donc déplaçable sous l'action du vérin 5 entre une position inclinée et la position représentée à la figure 1. Son mouvement vers le bas est assuré grâce à un vérin principal 10 par l'intermédiaire d'une bielle 11 en appui pivotant sur une potence centrale 12. La partie inférieure du vérin 10 s'articule sur un levier basculant 25 qui s'étend sous la platine, levier dont l'extrémité opposée supporte l'enclume 6. L'axe horizontal 4 se trouve à l'extrémité de la bielle 11. Un rupteur 13 est monté à l'extrémité d'un des bras 7 et relié au boîtier de commande d'un distributeur pneumatique 14 avantageusement monté sur la potence centrale.The crimping head 2 is thus movable under the action of the jack 5 between an inclined position and the position shown in FIG. 1. Its downward movement is ensured by means of a main jack 10 via a connecting rod 11. pivoting support on a central stem 12. The lower part of the jack 10 is articulated on a rocking lever 25 which extends under the plate, lever whose opposite end supports the anvil 6. The horizontal axis 4 is located at the end of the connecting rod 11. A switch 13 is mounted at the end of one of the arms 7 and connected to the control box of a pneumatic distributor 14 advantageously mounted on the central bracket.

On voit plus précisément à la figure 2 comment est réalisée l'enclume de sertissage et de découpe 6 présentée ici en position haute et qui est déplaçable entre une position basse où elle s'efface au-dessous du niveau de la platine-support, et cette position haute où elle déborde au-dessus de ladite platine. Elle a une forme parallélipipédique et sa face supérieure est équipée de deux ergots 8. L'extrémité d'une lamelle souple 16 fixée à la platine support 1 vient en appui sur la bordure de l'enclume. A côté de cette dernière est disposé un couteau 17, fixé à la platine par des vis 18, couteau dont la partie centrale forme un pont au-dessus de la platine, lequel couteau étant au contact de l'enclume.FIG. 2 shows more precisely how the crimping and cutting anvil 6 presented here in the upper position is made and which is movable between a low position where it disappears below the level of the support plate, and this high position where it overflows above said platen. It has a parallelepipedal shape and its upper face is equipped with two lugs 8. The end of a flexible blade 16 fixed to the support plate 1 bears on the edge of the anvil. Next to the latter is disposed a knife 17 fixed to the plate by screws 18, knife whose central portion forms a bridge above the plate, which knife is in contact with the anvil.

La figure 3 montre l'enclume 6 effacée au-dessous du niveau de la platine dans une ouverture 19. L'enclume est donc montée sur le levier 25 pour pouvoir occuper l'une ou l'autre des deux positions.Figure 3 shows the anvil 6 erased below the level of the plate in an opening 19. The anvil is mounted on the lever 25 to occupy one or the other of the two positions.

Quand elle est en position basse, on peut lui superposer l'extrémité du ruban d'attaches 20, ledit ruban étant passé sous le pont du couteau 17, comme on le voit plus précisément à la figure 4. Le ruban est formé d'une succession d'attaches reliées entre elles par des petites pattes de liaison 22 séparées par une prédécoupe 24. Cette prédécoupe est indispensable du fait de l'échancrure nécessaire dans le couteau 17 pour le passage des rosettes 23, la découpe du ruban étant impossible à de niveau. La prédécoupe 24 est donc localisée en alignement avec lesdites rosettes 23.When it is in the lower position, it can be superimposed on the end of the fastener tape 20, said tape being passed under the bridge of the knife 17, as can be seen more precisely in Figure 4. The tape is formed of a succession of fasteners interconnected by small connecting lugs 22 separated by a precut 24. This pre-cut is indispensable because of the notch required in the knife 17 to the passage of the rosettes 23, the cutting of the tape being impossible to level. The precut 24 is thus located in alignment with said rosettes 23.

Chaque attache porte, de façon connue en soi, des rosettes d'ancrage 23 séparées l'une de l'autre du même écartement que les ergots 8.Each fastener carries, in a manner known per se, anchoring rosettes 23 separated from one another by the same spacing as the lugs 8.

Le ruban d'attaches est donc positionné manuellement pour la première attache comme représenté à la figure 4. Le capot protecteur étant abaissé, la machine peut fonctionner de la façon suivante. Dans un premier temps on assure la levée de l'enclume 6 provoquée par le déploiement de la tige du vérin 10 ce qui libère le poids de ce dernier, poids s'exerçant sur le levier 25 dans le sens d'une montée de l'enclume 6 jusqù'à son contact avec la bande 20. Cela a pour effet de faire pénétrer les ergots 8 dans les rosettes 23 de la première attache, pour maintenir celle-ci dans une position correcte sur l'enclume, et d'arrêter le basculement du levier 25. Le déploiement de la tige du vérin se poursuit ce qui entraîne la descente de la tête de sertissage 2 par l'intermédiaire du levier 11. Simultanément, par cet effet de pincement, les pattes de liaison 22 entre la première et la seconde attache du ruban, sont cisaillées par l'arête du couteau 17, contre laquelle monte la bordure de l'enclume. La découpe de l'attache est facilitée par la prédécoupe 24 prévue entre les pattes de liaison. L'attache est maintenue en position sur l'enclume 6 par l'extrémité de la lamelle souple 16. La fixation de l'attache au carton est intervenue par l'effet de leur pincement entre la tête de sertissage 2 et l'enclume 6. Les traces éventuelles laissées par la tête de sertissage sur le carton le sont sur une face non visible. Ensuite un dispositif d'avance (préréglé en fonction de l'espacement entre deux attaches) positionne la seconde attache et les suivantes, évitant ainsi le positionnement manuel. Sans sortir du cadre de l'invention, on peut utiliser des rubans d'attaches de formes et de tailles différentes, pourvues d'une seule rosette d'ancrage 23 ou de plusieurs rosettes. L'enclume 6 est alors équipée d'un nombre d'ergots 8 correspondant au nombre de rosettes.The fastener tape is therefore manually positioned for the first fastener as shown in Figure 4. With the protective cover lowered, the machine can operate as follows. At first, the anvil 6 is lifted by the deployment of the rod of the jack 10, which releases the weight of the latter, the weight exerted on the lever 25 in the direction of a rise of the anvil 6 until it comes into contact with the strip 20. This has the effect of causing the lugs 8 to penetrate into the rosettes 23 of the first fastener, to hold the latter in a correct position on the anvil, and to stop the tilting of the lever 25. The deployment of the rod of the cylinder continues which causes the lowering of the crimping head 2 by means of the lever 11. Simultaneously, by this pinch effect, the connecting lugs 22 between the first and the second attachment of the ribbon, are sheared by the edge of the knife 17, against which rises the edge of the anvil. The cutting of the fastener is facilitated by the pre-cut 24 provided between the connecting lugs. The fastener is held in position on the anvil 6 by the end of the flexible blade 16. The fastening of the fastener to the carton has intervened by the effect of their nipping between the crimping head 2 and the anvil 6 Any traces left by the crimping head on the cardboard are on a non-visible face. Then an advance device (preset according to the spacing between two fasteners) positions the second and subsequent attachments, thus avoiding manual positioning. Without departing from the scope of the invention, it is possible to use fastener tapes of different shapes and sizes, provided with a single anchoring rosette 23 or with several rosettes. The anvil 6 is then equipped with a number of lugs 8 corresponding to the number of rosettes.
