  • the figure 1 is a side view which schematically shows a manual automatic apparatus for fitting a clamp according to the teachings of the invention.

DESCRIPTION DES MODES DE REALISATION PREFERESDESCRIPTION OF THE PREFERRED EMBODIMENTS

La figure 1 représente un appareil automatique manuel 10 pour poser des colliers de serrage 12 autour d'un faisceau de câbles 14. Bien entendu il peut être utilisé pour attacher des colliers de serrage 12 autour d'autres types de faisceaux ou autour d'autres objets tels qu'un ou plusieurs tubes, ou des brins possédant des dimensions compatibles avec l'envergure de l'appareil 10.The figure 1 shows a manual automatic device 10 for placing clamps 12 around a bundle of cables 14. Of course it can be used to attach clamps 12 around other types of bundles or around other objects such as one or more tubes, or strands having dimensions compatible with the scope of the device 10.

Les colliers de serrage 12 sont typiquement formés d'une sangle 16, ou ruban, en matière plastique souple munie à une extrémité libre d'une cage à cliquet 18 anti-retour. La sangle 16 est munie sur au moins une face de reliefs en dents de scie prévus pour coopérer avec le cliquet de la cage à cliquet 18.The clamps 12 are typically formed from a strap 16, or ribbon, of flexible plastic material provided at a free end with a non-return ratchet cage 18. The strap 16 is provided on at least one face with sawtooth reliefs provided to cooperate with the pawl of the pawl cage 18.

Selon le mode de réalisation représenté, l'appareil 10 comporte un boîtier 20 muni d'une poignée 22 en forme de crosse de pistolet avec un interrupteur ou gâchette 24 permettant de déclencher une opération de pose de collier. Le boîtier 20 comporte de préférence un magasin 26 amovible prévu pour contenir une réserve de colliers de serrage 12 avant leur pose et un réceptacle 28 prévu pour recevoir les extrémités sectionnées des colliers de serrage 12 après leur pose sur un faisceau de câbles 14.According to the embodiment shown, the apparatus 10 comprises a housing 20 provided with a handle 22 in the form of a pistol grip with a switch or trigger 24 making it possible to trigger a collar fitting operation. The housing 20 preferably comprises a removable magazine 26 designed to contain a reserve of clamps 12 before their installation and a receptacle 28 designed to receive the cut ends of the clamps 12 after their installation on a bundle of cables 14.

Pour permettre la pose des colliers de serrage 12, l'appareil 10 est pourvu d'un mécanisme intégré de pose 30, ou dispositif de positionnement. Dans l'exemple représenté schématiquement, le mécanisme de pose 30 comporte un dispositif d'alimentation 32 prévu pour entraîner les colliers de serrage 12 depuis le magasin 26 vers une mâchoire supérieure 34 et une mâchoire inférieure 36 pivotantes servant à former une boucle du collier de serrage 12 autour du faisceau de câbles 14.To allow the installation of the clamps 12, the apparatus 10 is provided with an integrated installation mechanism 30, or positioning device. In the example shown schematically, the setting mechanism 30 comprises a feed device 32 provided to drive the clamps 12 from the magazine 26 to an upper jaw 34 and a lower jaw 36 pivoting for forming a loop of the clamp. clamp 12 around the wire harness 14.

Le mécanisme intégré de pose 30 comporte un premier moteur électrique 37 muni d'un premier arbre d'entraînement 39 qui est pourvu de préférence de trois cames, une première came commandant la mâchoire supérieure 34, une seconde came commandant la mâchoire inférieure 36, et une troisième came commandant un dispositif de sectionnement 52. Ce premier arbre d'entraînement 39 est prévu pour faire exactement un tour complet au cours d'un cycle de fonctionnement complet de l'appareil.The integrated delivery mechanism 30 comprises a first electric motor 37 provided with a first drive shaft 39 which is preferably provided with three cams, a first cam controlling the upper jaw 34, a second cam controlling the lower jaw 36, and a third cam controlling a sectioning device 52. This first drive shaft 39 is designed to make exactly one complete revolution during a complete operating cycle of the apparatus.

On appelle ici cycle de fonctionnement de l'appareil un cycle complet de pose d'un collier de serrage 12 sur un faisceau de câbles 14, l'appareil 10 étant prêt pour poser à nouveau un collier de serrage 12 à la fin du cycle.The operating cycle of the apparatus is referred to here as a complete cycle of placing a clamp 12 on a bundle of cables 14, the apparatus 10 being ready to install a clamp 12 again at the end of the cycle.

L'appareil 10 comporte aussi un dispositif de tension 38 qui entraîne l'extrémité libre du collier de serrage 12 à la sortie de la cage à cliquet 18 dans le sens du serrage autour du faisceau de câbles 14.The apparatus 10 also comprises a tension device 38 which drives the free end of the clamp 12 at the exit of the ratchet cage 18 in the direction of tightening around the wire harness 14.

L'appareil 10 comporte une unité électronique 40 qui commande le mécanisme de pose 30 de manière adéquate en fonction du signal donné par la gâchette 24 et en fonction des réglages saisis par un opérateur grâce à une interface de commande 42. L'interface de commande 42 comporte par exemple un écran d'affichage 44 ainsi que des boutons de commande 46.The apparatus 10 comprises an electronic unit 40 which controls the delivery mechanism 30 in an adequate manner according to the signal given by the trigger 24 and according to the settings entered by an operator by means of a control interface 42. The control interface 42 comprises for example a display screen 44 as well as control buttons 46.

L'appareil 10 comporte également un système d'alimentation électrique (non représenté).The apparatus 10 also includes an electrical supply system (not shown).

Le dispositif de tension 38 est ici équipé d'une roue dentée 48 qui est prévue pour engrener avec la partie dentée du collier de serrage 12 de manière à l'entraîner dans le sens du serrage. Le dispositif de tension 38 comporte un second moteur électrique 49 qui entraîne en rotation la roue dentée 48.The tension device 38 is here equipped with a toothed wheel 48 which is provided to mesh with the toothed part of the clamp 12 so as to drive it in the direction of tightening. The tension device 38 comprises a second electric motor 49 which drives the toothed wheel 48 in rotation.

Avantageusement, la roue dentée 48 est équipée d'un encodeur rotatif 50 qui permet de compter indirectement le nombre de dents qui ont engrené avec la roue dentée 48. Il est possible ainsi de déterminer très précisément la circonférence restante autour du faisceau de câbles 14 en déterminant le nombre dents de la partie libre du collier de serrage 12 extraite à la sortie de la cage à cliquet 18.Advantageously, the toothed wheel 48 is equipped with a rotary encoder 50 which makes it possible to indirectly count the number of teeth which have meshed with the toothed wheel 48. It is thus possible to very precisely determine the remaining circumference around the bundle of cables 14 by determining the number of teeth of the free part of the clamp 12 extracted at the exit of the ratchet cage 18.

L'encodeur rotatif 50 est raccordé à l'unité électronique 40 ce qui permet à l'unité électronique 40 de commander précisément le second moteur électrique 49 et la rotation de la roue dentée 48 en fonction du signal de l'encodeur rotatif 50.The rotary encoder 50 is connected to the electronic unit 40 which enables the electronic unit 40 to precisely control the second electric motor 49 and the rotation of the toothed wheel 48 according to the signal from the rotary encoder 50.

Avantageusement, l'appareil 10 comporte un dispositif de sectionnement 52 qui permet de sectionner la sangle du collier de serrage 12 juste à la sortie de la cage à cliquet 18, après que la boucle de circonférence appropriée ait été formée autour du faisceau de câbles 14. Le dispositif de sectionnement 52 permet donc de retirer la partie inutilisée du collier de serrage 12.Advantageously, the apparatus 10 comprises a severing device 52 which makes it possible to sever the strap of the clamp 12 just at the exit of the ratchet cage 18, after the loop of appropriate circumference has been formed around the wire harness 14. The severing device 52 therefore makes it possible to remove the unused part of the clamp 12.

L'interface de commande 42 permet à l'utilisateur de l'appareil 10 de choisir un mode opératoire de l'appareil 10. Un mode opératoire dit standard comprend un cycle au cours duquel le collier de serrage 12 est d'abord serré autour du faisceau de câbles 14 puis, en fin de cycle, le collier de serrage 12 est sectionné de manière à éliminer le tronçon d'extrémité libre du collier 12.The control interface 42 allows the user of the apparatus 10 to choose an operating mode of the apparatus 10. A so-called standard operating mode comprises a cycle during which the clamp 12 is first tightened around the. cable harness 14 then, at the end of the cycle, the clamp 12 is cut so as to eliminate the free end section of the clamp 12.

Avantageusement, l'interface de commande 42 est configurée pour commander l'appareil 10 dans au moins un autre mode opératoire dit mode opératoire sans sectionnement, où l'étape de sectionnement du collier de serrage 12 en fin de cycle est supprimée. Pour cela, l'unité électronique 40 est configurée pour, dans le mode opératoire sans sectionnement, inverser le sens de rotation du second moteur 49 en fin de cycle de manière à éjecter le collier de serrage 12 de l'appareil 10 avant que le sectionnement n'ait eu lieu.Advantageously, the control interface 42 is configured to control the device 10 in at least one other operating mode known as the operating mode without sectioning, where the step of sectioning the clamp 12 at the end of the cycle is omitted. For this, the electronic unit 40 is configured for, in the operating mode without sectioning, reverse the direction of rotation of the second motor 49 at the end of the cycle so as to eject the clamp 12 from the device 10 before the sectioning has taken place.

Une méthode de commande de l'appareil automatique manuel 10 dans le mode opératoire standard comprend les étapes suivantes :

  1. a) commander le premier moteur électrique entraînant le mécanisme intégré de pose 30 de manière à positionner le collier 12 en boucle fermée autour du faisceau de câbles 14,
  2. b) commander le second moteur électrique entraînant le dispositif de tension 38 de manière à serrer le collier 12 autour du faisceau de câbles 14,
  3. c) commander le premier moteur électrique entraînant le dispositif de sectionnement 52 de manière à sectionner la partie inutilisée du collier 12 en fin de cycle, après le serrage du collier autour du faisceau de câbles 14.
A method of controlling the manual automatic apparatus 10 in the standard operating mode comprises the following steps:
  1. a) control the first electric motor driving the integrated laying mechanism 30 so as to position the collar 12 in a closed loop around the wire harness 14,
  2. b) control the second electric motor driving the tension device 38 so as to tighten the collar 12 around the wire harness 14,
  3. c) control the first electric motor driving the disconnection device 52 so as to cut the unused part of the clamp 12 at the end of the cycle, after the clamp has been tightened around the wire harness 14.

Dans le mode opératoire sans sectionnement, l'appareil 10 est commandé selon les étapes suivantes :

  • al) commander le premier moteur électrique entraînant le mécanisme intégré de pose 30 de manière à positionner le collier 12 en boucle fermée autour du faisceau de câbles 14,
  • b1) commander le second moteur électrique entraînant le dispositif de tension 38 de manière à serrer le collier 12 autour du faisceau de câbles 14 jusqu'à l'arrêt du moteur électrique correspondant à une tension complète du collier sur le faisceau de câbles 14,
  • cl) commander le second moteur électrique en rotation inversée, par rapport au sens de rotation servant à tendre le collier 12, en fin de cycle, après l'étape b1) de manière à éjecter le collier de serrage de l'appareil 10 avant que le sectionnement n'ait eu lieu.
In the operating mode without sectioning, the device 10 is controlled according to the following steps:
  • al) control the first electric motor driving the integrated fitting mechanism 30 so as to position the collar 12 in a closed loop around the wire harness 14,
  • b1) control the second electric motor driving the tension device 38 so as to tighten the collar 12 around the wire harness 14 until the electric motor stops, corresponding to full tension of the collar on the wire harness 14,
  • c) control the second electric motor in reverse rotation, with respect to the direction of rotation serving to tension the collar 12, at the end of the cycle, after step b1) so as to eject the clamp from the device 10 before the sectioning has not taken place.
