  • the invention lies in the technical field of automated closing of the frames and door more precisely on an automatic machine for laying flexible tips.
  • a machine to install nails to using a driving system the nails coming from a distribution store, a detector being able to signal the absence of nails in the store.
  • a carriage can move longitudinally on rails. He wears one or more pistols, stapling. Each pistol is equipped with a flexible tip charger that should obviously be replace where to replenish, in case of jamming or when the spikes are exhausted. So this involves manipulation manual, with a temporary stop of the machine. It is also possible to use a recharging device automatic chargers, but this leads to heavy and expensive mechanisms. In addition these do not do not solve problems related to incidents of gun operation.
  • the invention proposes a solution which consists in having in the vicinity of the station of work, a rack for the storage of pre-filled pistols flexible tips, which the machine will pick up as and as the contents of the pistols are stripped instead use the same gun (s) and refill them with tips.
  • the main object of the invention is therefore a machine automatic to place flexible tips on a frame comprising a mobile carriage carrying a laying gun, which is movable above a trained workstation of a table carrying an endless band, said pistol containing a store full of drop-in points and the machine comprising a tip detector, characterized in that the machine is equipped with a rack for the storage of several pre-filled guns with spikes, rack which is accessible to a gripper of a pistol, gripper carried by said carriage, and in that the detector is mounted on the pistol to be able to notice the absence of a point in the frame at the place of installation, and order the operation of the clamp in the direction of the rack.

  • the latter has two lateral sides 11 forming a vice, between which houses the pistol 8. These sides can open away from each other, side pins 12 providing guidance during this spacing.
  • a lever 13 is articulated, actuator of the pistol trigger. Automatic air supply to the pistol is provided with a seal placed on the side of the sealing pliers.
  • a first assumption is that the gun has not supplied as it is empty, this being confirmed by counting the peaks posed in relation to the capacity gun.
  • the carriage 5 and its pivoting lever 6 are then move, to deposit the empty pistol on the rack 10 and take another full one, then for return to the top of frame 14 at the location of the last tip, to continue the laying cycle.
  • a second hypothesis is that there is an anomaly of gun operation, detected by counting raised tips, which do not correspond to the total of tips stored at the start in the pistol.

Description

L'invention se situe dans le domaine technique de la fermeture automatisée des cadres et porte plus précisément sur une machine automatique à poser des pointes flexibles. On connait par le DE 4405661 une machine à poser des clous à l'aide d'un système d'enfoncement, les clous provenant d'un magasin de distribution, un détecteur étant apte à signaler l'absence de clous dans le magasin .
On connaít aussi divers types de machines adaptées aux cadres dont l'une permet de poser automatiquement une pluralité de pointes flexibles sur les baguettes du cadre pour en assurer la fermeture par un carton. Pour cela, au dessus d'un poste de travail, avantageusement un convoyeur à bande sans fin, un chariot peut se déplacer longitudinalement sur des rails. Il porte un ou plusieurs pistolets, d'agrafage. Chaque pistolet est équipé d'un chargeur de pointes flexibles qu'il convient évidemment de remplacer où de regarnir, en cas d'enrayement ou quand les pointes sont épuisées. Cela implique donc une manipulation manuelle, avec un arrêt provisoire de la machine. Il est aussi possible d'utiliser un dispositif de rechargement automatique des chargeurs, mais cela conduit à des mécanismes lourds et coûteux. En outre ceux-ci ne solutionnent pas les problèmes liés aux incidents de fonctionnement des pistolets. De plus ces machines n'utilisent qu'un ou plusieurs pistolets, chacun d'eux ayant une ou plusieurs pointes à poser à un ou plusieurs endroits déterminés. L'utilisateur doit donc assurer un contrôle visuel et constant de la présence ou de l'absence de pointes. En cas d'absence de pointe il doit déterminer quel pistolet est défaillant, puis arrêter la machine et le remplacer. On encoure le risque, en plus de pertes de productivité, d'obtenir un produit non conforme.
En vue d'éviter ces inconvénients l'invention propose une solution qui consiste à disposer au voisinage du poste de travail, un râtelier de stockage de pistolets préremplis de pointes flexibles, que la machine viendra chercher au fur et à mesure du dégarnissage du contenu des pistolets au lieu d'utiliser le ou les mêmes pistolets et de les regarnir de pointes.
L'invention a donc pour objet principal une machine automatique à poser des pointes flexibles sur un cadre comportant un chariot mobile porteur d'un pistolet de pose, qui est déplaçable au dessus d'un poste de travail formé d'une table portant une bande sans fin, ledit pistolet renfermant un magasin rempli de pointes à poser et la machine comportant un détecteur de pointes, caractérisée en ce que la machine est équipée d'un râtelier pour le stockage de plusieurs pistolets préremplie de pointes, râtelier qui est accessible à une pince de préhension d'un pistolet, pince portée par ledit chariot, et en ce que le détecteur est monté sur le pistolet pour être en mesure de constater l'absence d'une pointe dans le cadre à l'endroit de la pose, et commande la manoeuvre de la pince en direction du râtelier.
Des caractéristiques particulières et avantages de l'invention ressortiront de la description qui va suivre d'un exemple non limitatif de réalisation dans lequel il est fait référence aux dessins annexés qui représentent :
  • Figure 1, une vue générale en perspective de la machine automatique.
  • Figure 2, une vue en élévation de la pince et du pistolet en position de travail au dessus d'une table.
  • Figure 3, une vue éclatée en perspective montrant la pince et le pistolet séparés l'un de l'autre.
    • Sur la vue d'ensemble de la machine à la figure 1, on voit que le poste de travail est formé d'une table 1, portant une bande mobile sans fin 2 et transversalement à chaque extrémité, un rail 3. Sur ces rails se déplace un pont roulant 4 qui lui-même supporte un chariot mobile 5. Le chariot déplaçable longitudinalement sur le pont roulant et transversalement par les rails 3, est donc apte à couvrir toute la surface du poste de travail. Sous le chariot 5 est accroché un levier pivotant 6 sur lequel s'articule une pince 7 qui elle-même porte pistolet 8 destiné à la pose des pointes sur le cadre, comme le montre également la figure 2. Un vérin de positionnement 9 permet de donner à la pince, et par conséquent au pistolet, l'inclinaison recherchée par rapport à la bande 2 sur laquelle est immobilisée temporairement le cadre 14 à fermer.
    Sur le côté de la table 1 est disposé un râtelier 10, supportant, rangés les uns à côté des autres, un certain nombre de pistolets 8 préchargés de pointes flexibles. Le râtelier est accessible à la pince de préhension 7 portée par le chariot 5, et il est avantageusement disposé en avant de la table 1 et au niveau de la bande transporteuse 2.
    La figure 3 illustre plus précisément comment est assuré l'accrochage du pistolet 8 à la pince 7. Celle-ci dispose de deux flancs latéraux 11 formant étau, entre lesquels vient se loger le pistolet 8. Ces flancs peuvent s'ouvrir en s'écartant l'un de l'autre, des pions latéraux 12 assurant un guidage lors de cet écartement. Sur un côté d'un des flancs, s'articule un levier 13, actionneur de la gâchette du pistolet. Une alimentation automatique d'air au pistolet est prévue avec un joint placé sur le côté de la pince pour l'étanchéité.
    On voit à la figure 2 le pistolet 8 incliné et en appui contre une moulure de cadre 14. La pince tenant le pistolet possède un petit vérin disposé à l'aplomb de la pointe et est muni d'un détecteur 15. Le vérin rabat la pointe sur le carton, en constatant sa présence.
    Si le détecteur (15) constate l'absence d'une pointe dans le cadre à l'endroit considéré, c'est-à-dire l'endroit de la pose, une première hypothèse est que le pistolet n'a pas fourni de pointe car il est vide, ceci étant confirmé par le comptage des pointes posées par rapport à la capacité du pistolet. Le chariot 5 et son levier pivotant 6 se déplacent alors, pour aller déposer le pistolet vide sur le râtelier 10 et en reprendre un autre plein, puis pour revenir au dessus du cadre 14 à l'emplacement de la dernière pointe, afin de poursuivre le cycle de pose.
    Une seconde hypothèse est qu'il y a une anomalie de fonctionnement du pistolet, décelée par le comptage des pointes posées, qui ne correspondent pas au total des pointes emmagasinées au départ dans le pistolet. Ce dernier peut revenir en arrière pour essayer à nouveau une pose, mais en cas de nouvel échec le pistolet est reconduit au râtelier 10 et remplacé par un autre, comme dans le cas précédent.
    Toutes ces manoeuvres sont évidemment gérées par ordinateur, et les informations "pistolet vide" ou "pistolet enrayé" s'affichent sur l'écran de la console de commande.
    La machine permet ainsi d'obtenir une cadence horaire élevée de poses de pointes.
