Description

La présente invention est relative, en particulier dans les distributeurs automatiques d'étiquettes prélevées sur un ruban, au chargement et au positionnement convenables du ruban.The present invention relates, in particular in automatic dispensers for labels taken from a ribbon, to the proper loading and positioning of the ribbon.

Dans les distributeurs automatiques d'étiquettes, pour machines ou ensembles d'affranchissement postal, il est connu de venir prélever les étiquettes d'affranchissement sur un ruban continu entraîné de manière intermittente et au fur et à mesure sectionné, pour délivrer les étiquettes successives à la longueur souhaitée.In automatic label dispensers, for machines or sets of postage franking, it is known to pick up the franking labels on a continuous ribbon driven intermittently and progressively sectioned, to deliver the successive labels to the desired length.

La présente invention a pour but de permettre un chargement aisé et rapide dudit ruban en assurant simultanéement son positionnement convenable.The present invention aims to allow easy and rapid loading of said tape while simultaneously ensuring its proper positioning.

La présente invention a donc pour objet un dispositif de chargement et de positionnement d'un ruban dans une machine équipée de moyens de guidage du ruban définissant le chemin du ruban entre une entrée et une sortie sur la machine et de moyens d'entraînement du ruban comportant au moins un premier rouleau monté sur un premier arbre entraîné en rotation par une commande manuelle extérieure, ledit dispositif étant caractérisé en ce qu'il comporte un bras de commande présentant d'une part un doigt dont l'extrémité forme obstable basculant effaçable dans ledit chemin sous l'effet de l'extrémité du ruban entraîné dans le chemin, pour constituer un levier de commande dudit bras et, d'autre part une griffe dont l'extrémité vient bloquer ledit premier arbre lorsque ledit obstable est effacé.The present invention therefore relates to a device for loading and positioning a ribbon in a machine equipped with means for guiding the ribbon defining the path of the ribbon between an inlet and an outlet on the machine and means for driving the ribbon. comprising at least a first roller mounted on a first shaft driven in rotation by an external manual control, said device being characterized in that it comprises a control arm having on the one hand a finger whose end forms an obstructable tilting erasable in said path under the effect of the end of the ribbon driven in the path, to constitute a control lever of said arm and, on the other hand, a claw whose end comes to block said first shaft when said obstable is erased.

Selon une particularité de l'invention ledit bras est maintenu élastiquement sur la machine par des moyens assurant l'insertion de l'extrémité dudit doigt dans ledit chemin, en l'absence de ruban.According to a feature of the invention, said arm is held elastically on the machine by means ensuring the insertion of the end of said finger in said path, in the absence of ribbon.

Selon une autre particularité de l'invention, ladite commande extérieure est un bouton formé en deux parties sensiblement de même diamètre présentant une couronne périphérique crantée sur l'une de leur face pour leur assemblage l'une à la suite de l'autre le long de l'extrémité dudit premier arbre, ladite partie terminale étant libre en rotation sur ledit premier arbre et maintenue élastiquement contre l'autre partie qui assure l'entraînement dudit arbre ou est bloquée par ladite griffe.According to another feature of the invention, said external control is a button formed in two parts of substantially the same diameter having a peripheral crown notched on one of their faces for their assembly one after the other along from the end of said first shaft, said end part being free to rotate on said first shaft and held elastically against the other part which ensures the drive of said shaft or is blocked by said claw.

  • - Figures 3 and 4 show, seen from the side and seen from the front, the control mechanism associated with the manual tape drive mechanism in the dispenser together constituting the tape loading and positioning device according to the invention.

Dans la figure 1, on a illustré une machine de distribution d'étiquettes prélevées sur un ruban, ou distributeur d'étiquettes, par sa partie qui définit le chemin de défilement de ruban dans le châssis de la machine formé de deux demi-coquilles 1 et 2 assemblées l'une à l'autre.In FIG. 1, a machine for dispensing labels taken from a ribbon, or label dispenser, has been illustrated by its part which defines the path of travel of the ribbon in the chassis of the machine formed by two half-shells 1 and 2 assemblies to each other.

Dans la figure 1, on voit que le chemin de défilement du ruban est défini par deux goulottes rigides 3 et 4. La goulotte 3 définit sur la demi-coquille supérieure 1 du châssis une entrée 5 de ruban, elle est fixée par vis telles que 6 au niveau de cette entrée 5 sur la demi-coquille 1. La goulotte 4 définit sur la demi-coquille inférieure 2 du châssis une sortie 7 d'étiquettes, des tiges de maintien 8 et 9 engagées dans des pattes d'accrochage prévues sur cette goulotte et sur cette demi-coquille assurent sa fixation sur la demi-coquille 2. Ces deux goulottes 3 et 4 sont cintrées pour occuper dans le distributeur sensiblement la hauteur et la largeur du châssis.In FIG. 1, it can be seen that the tape running path is defined by two rigid troughs 3 and 4. The trough 3 defines an inlet 5 on the upper half-shell 1 of the chassis, it is fixed by screws such that 6 at the level of this inlet 5 on the half-shell 1. The chute 4 defines on the lower half-shell 2 of the chassis an outlet 7 for labels, holding rods 8 and 9 engaged in lugs provided on this chute and this half-shell ensure its attachment to the half-shell 2. These two chutes 3 and 4 are bent to occupy in the dispenser substantially the height and width of the chassis.

Les deux autres extrémités des goulottes 3 et 4 sont reliées à l'intérieur du châssis par un couteau 10, à lame fixe 11 et à lame mobile 12, interposé entre elles. Ce couteau 10 est maintenu par des vis telles que 13 sur la demi-coquille supérieure 1 du châssis. Sa lame fixe 11 est montée sur un support 14 de section en forme de U, à fond semi-circulaire présentant une fenêtre 15 sous la lame fixe 11 pour le passage du ruban. Sa lame mobile 12 est de section semi-circulaire ; elle est fixée sur les extrémités d'un support 16, en laissant un intervalle entre elle et son support sur la longueur de la fenêtre 15. Cette lame 12 et son support 16 forment un ensemble monté pivotant dans le support 14 et un support auxiliaire 17 à pattes d'accrochage 18 venant s'encliqueter sur des ergots en relief extérieurement sur les branches du support en U 14.The other two ends of the troughs 3 and 4 are connected to the inside of the chassis by a knife 10, with a fixed blade 11 and a movable blade 12, interposed between them. This knife 10 is held by screws such as 13 on the upper half-shell 1 of the chassis. Its fixed blade 11 is mounted on a support 14 of U-shaped section, with a semi-circular bottom having a window 15 under the fixed blade 11 for the passage of the ribbon. Its movable blade 12 is of semi-section circular; it is fixed to the ends of a support 16, leaving a gap between it and its support over the length of the window 15. This blade 12 and its support 16 form an assembly pivotally mounted in the support 14 and an auxiliary support 17 with latching lugs 18 which snap onto lugs in relief externally on the branches of the U-shaped support 14.

Ce support 17 présente également une fenêtre 20 au droit de la fenêtre 15 pour le passage du ruban.This support 17 also has a window 20 to the right of the window 15 for the passage of the ribbon.

Des moyens d'entraînement assurent l'entraînement du ruban et des étiquettes sur ce chemin de défilement. Ces moyens comportent, sur la partie de chemin défini par la goulotte 3, un rouleau 25 d'un côté de cette goulotte et deux galets presseurs 26 et 27 de l'autre côté de la goulotte, ce rouleau et ces galets viennent à travers des fenêtres convenables, non représentées, dans les parois de la goulotte, s'interposer sur le chemin pour permettre l'entraînement du ruban.Driving means ensure the driving of the tape and the labels on this running path. These means comprise, on the part of the path defined by the chute 3, a roller 25 on one side of this chute and two pressure rollers 26 and 27 on the other side of the chute, this roller and these rollers come through suitable windows, not shown, in the walls of the chute, to be interposed on the path to allow the ribbon to drive.

Le rouleau 25 est monté solidaire en rotation sur un arbre de transmission 30 fixé par des paliers 31 formant bague d'accrochage sur la demi-coquille supérieure 1 du châssis. Les deux galets presseurs 26 et 27 sont montés libres en rotation sur un berceau support 28 maintenu élastiquement sur la demi-coquille inférieure 2, pour appliquer les galets contre le rouleau 25.The roller 25 is mounted integral in rotation on a transmission shaft 30 fixed by bearings 31 forming a hooking ring on the upper half-shell 1 of the chassis. The two pressure rollers 26 and 27 are mounted to rotate freely on a support cradle 28 held resiliently on the lower half-shell 2, to apply the rollers against the roller 25.

Les moyens d'entraînement comportent aussi, sur la partie du chemin défini par la goulotte 4, un rouleau 35 et deux galets presseurs associés 36 et 37 disposés de part et d'autre de la goulotte et venant à travers des fenêtres convenables dans la goulotte, non représentées, coopérer pour l'entraînement d'étiquettes coupées dans le ruban. Ce rouleau 35 et les galets 36 et 37 sont montés de manière analogue à l'ensemble précédent. Le rouleau 35 est solidaire en rotation d'un arbre de transmission 40 qui le porte, fixé par des paliers non représentés formant bague d'accrochage sur la demi-coquille inférieure 2 du châssis. Les deux galets presseurs 36 et 37 sont montés libres en rotation sur un support 38 maintenu élastiquement sur la demi-coquille inférieure pour appliquer les galets contre le rouleau 35.The drive means also comprise, on the part of the path defined by the chute 4, a roller 35 and two associated pressure rollers 36 and 37 arranged on either side of the chute and coming through suitable windows in the chute , not shown, cooperate for the drive of labels cut from the ribbon. This roller 35 and the rollers 36 and 37 are mounted in a similar manner to the previous assembly. The roller 35 is integral in rotation with a transmission shaft 40 which carries it, fixed by bearings not shown forming hooking ring on the lower half-shell 2 of the chassis. The two pressure rollers 36 and 37 are mounted to rotate freely on a support 38 held elastically on the lower half-shell to apply the rollers against the roller 35.

Les deux arbres 30 et 40 portant les rouleaux 25 et 35 d'entraînement du ruban et des étiquettes sont couplés l'un à l'autre. Ces moyens de couplage ont été rapportés en pointillés dans la figure 1 bien que disposés dans le distributeur devant les plans de coupe de cette figure. Ils sont constitués par une courroie crantée 41 engagée entre un pignon cranté 42 à l'extrémité de l'arbre 40 et un autre pignon cranté 32 à l'extrémité de l'arbre 30, pour la transmission du mouvement d'un arbre à l'autre.The two shafts 30 and 40 carrying the rollers 25 and 35 for driving the ribbon and the labels are coupled to each other. These coupling means have been reported in dotted lines in FIG. 1 although they are arranged in the distributor in front of the section planes of this figure. They consist of a toothed belt 41 engaged between a toothed pinion 42 at the end of the shaft 40 and another toothed pinion 32 at the end of the shaft 30, for the transmission of movement from a shaft to the 'other.

Au droit du rouleau 35, le chemin de défilement défini par la goulotte 4 est barré par l'extrémité recourbée d'un doigt 45 effaçable par la seule pression du bout du ruban. Ce doigt 45 est monté parallèlement à la goulotte sur un bras 46. En l'absence de ruban l'extrémité recourbée de ce doigt vient s'engager à travers les fenêtres en vis-à- vis 47 et 48 prévues dans les parois de la goulotte 4 en formant obstable basculant effaçable sur le chemin du ruban. La longueur du chemin défilement comprise entre le couteau 10 et l'extrémité de ce doigt 45 est égale à une première longueur choisie d'étiquettes.In line with the roller 35, the travel path defined by the chute 4 is barred by the curved end of a finger 45 which can be erased by the single press of the end of the ribbon. This finger 45 is mounted parallel to the chute on an arm 46. In the absence of a ribbon, the curved end of this finger engages through the facing windows 47 and 48 provided in the walls of the chute 4 forming an obstructable tilting erasable on the ribbon path. The length of the running path between the knife 10 and the end of this finger 45 is equal to a first chosen length of labels.

A proximité du couteau 10, un arbre 50 monté sur la demi-coquille supérieure par des paliers ou bagues d'accrochage non représentés, permet la commande d'actionnement du couteau 10.Near the knife 10, a shaft 50 mounted on the upper half-shell by bearings or hooking rings, not shown, enables the knife 10 to be actuated.

Cet arbre 50 s'étend parallèlement à la lame mobile 12 du couteau 10. Un couplage entre une extrémité de cet arbre 50 et une extrémité de la lame 12, ou son support 16, du type bielle-manivelle en tant que tel connu et non représenté, permet l'actionnement du couteau 10 à partir de l'arbre 50.This shaft 50 extends parallel to the movable blade 12 of the knife 10. A coupling between one end of this shaft 50 and one end of the blade 12, or its support 16, of the connecting rod-crank type as such known and not known shown, allows actuation of the knife 10 from the shaft 50.

Les commandes en rotation de l'arbre 50 d'actionnement du couteau 10 et l'arbre 30 d'entraînement du rouleau 25, et donc de l'arbre 40 d'entraînement du rouleau 35 du fait du couplage de ces arbres par la courroie crantée 41 montée entre leurs pignons 32, 42, sont prélevées d'un arbre central de commande 60 maintenu par des paliers ou bagues d'accrochage 61 sur la demi-coquille inférieure 2, présentant des flasques intermédiaires convenables à cet effet. Pour les commandes de l'arbre 50 d'actionnement du couteau et de l'arbre 30 d'entraînement du rouleau, à partir de l'arbre 60, on a schématisé en 70 sur l'arbre 60, en 85 sur l'arbre 30 et 86 sur l'arbre 50 les mécanismes de couplage entre ces arbres. Ces mécanismes de couplage sont par exemple ceux faisant l'objet de la demande de brevet intitulé "Distributeur automatique d'étiquettes en ruban" déposée ce même jour par la Demanderesse. Ils assurent l'entraînement du ruban pour une longueur souhaitée d'étiquettes puis, à l'arrêt du ruban, l'actionnement du couteau.The rotational commands of the shaft 50 for actuating the knife 10 and the shaft 30 for driving the roller 25, and therefore for the shaft 40 for driving the roller 35 due to the coupling of these shafts by the belt. notched 41 mounted between their pinions 32, 42, are taken from a central control shaft 60 held by bearings or hooking rings 61 on the lower half-shell 2, having intermediate flanges suitable for this purpose. For the commands of the knife actuation shaft 50 and of the roller drive shaft 30, from the shaft 60, we have diagrammatically shown at 70 on the shaft 60, at 85 on the shaft 30 and 86 on the shaft 50 the coupling mechanisms between these shafts. These coupling mechanisms are, for example, those which are the subject of the patent application. entitled "Automatic tape label dispenser" filed on the same day by the Applicant. They drive the ribbon for a desired length of labels and then, when the ribbon stops, actuating the knife.

Dans le mécanisme d'entraînement du ruban monté sur les arbres 30 et 40, couplés par la courroie 41, la partie portée par l'arbre 40 assure également le chargement manuel du ruban dans le dispositif et coopère avec le mécanisme de commande monté sur le bras 46 pour le positionnement du ruban.In the ribbon drive mechanism mounted on the shafts 30 and 40, coupled by the belt 41, the part carried by the shaft 40 also ensures manual loading of the ribbon into the device and cooperates with the control mechanism mounted on the arm 46 for positioning the ribbon.

On a illustré séparément dans la figure 2 l'équipement monté sur l'arbre 40 pour le chargement manuel du ruban et dans les figures 3 et 4 le mécanisme de commande associé monté sur le bras 46.The equipment mounted on the shaft 40 for manual loading of the ribbon has been illustrated separately in FIG. 2 and in FIGS. 3 and 4 the associated control mechanism mounted on the arm 46.

L'arbre 40 porte le rouleau 35 et le pignon denté 42 de couplage par la courroie précitée avec l'arbre 30 (figure 1).The shaft 40 carries the roller 35 and the toothed pinion 42 for coupling by the aforementioned belt with the shaft 30 (Figure 1).

Il porte également deux paliers ou bagues d'accrochage 44 et, à une extrémité extérieure au châssis, un bouton de commande manuelle 43. Ce bouton 43 est formé en deux parties 81 et 82 sensiblement de même diamètre extérieur et assemblées l'une à la suite de l'autre sur l'extrémité de l'arbre 40. La partie 81, la plus intérieure sur l'arbre 40, assure l'entraînement de l'arbre duquel elle est solidaire par un palier 83. Elle présente une denture périphérique 84 avec laquelle vient coopérer le mécanisme porté par le bras 46, ainsi qu'il sera décrit ci-après.It also carries two bearings or hooking rings 44 and, at one end external to the chassis, a manual control button 43. This button 43 is formed in two parts 81 and 82 of substantially the same external diameter and assembled one to the other. following the other on the end of the shaft 40. The part 81, the innermost on the shaft 40, drives the shaft of which it is secured by a bearing 83. It has peripheral teeth 84 with which the mechanism carried by the arm 46 cooperates, as will be described below.

Elle présente sur l'une de ses faces, pour son assemblage avec la partie 82, une couronne périphérique crantée 85. La partie terminale 82 présente en correspondance sur l'une de ses faces une couronne périphérique crantée 86, venant s'encastrer dans la couronne 85. Cette partie 82 est maintenue élastiquement assemblée sur la partie 81 par l'effet d'un ressort 87. Ce ressort 87 est monté prisonnier entre le fond d'une cage 88 définie dans la face terminale de cette partie 82 et une bague 89 fermant la cage et maintenue par un circlips 90 sur l'arbre 41. Cette partie 82 est montée libre en rotation sur l'arbre 40. Elle est couplée à l'arbre 40 par la partie 81. Des cannelures 91 sur la périphérie de la partie 82 facilite l'actionnement manuel du bouton résultant 43 pour l'entraînement de l'arbre 40.It has on one of its faces, for its assembly with the part 82, a notched peripheral ring 85. The end portion 82 has in correspondence on one of its faces a notched peripheral ring 86, which is embedded in the crown 85. This part 82 is held elastically assembled on the part 81 by the effect of a spring 87. This spring 87 is mounted captive between the bottom of a cage 88 defined in the end face of this part 82 and a ring 89 closing the cage and maintained by a circlip 90 on the shaft 41. This part 82 is mounted to rotate freely on the shaft 40. It is coupled to the shaft 40 by the part 81. Splines 91 on the periphery of the part 82 facilitates manual actuation of the resulting button 43 for driving the shaft 40.

Le mécanisme de commande monté sur le bras 46 comporte le doigt précité 45, qui constitue un levier de commande, une griffe terminale 93 et un levier élastique de rappel intermédiaire 94.The control mechanism mounted on the arm 46 comprises the aforementioned finger 45, which constitutes a control lever, a terminal claw 93 and an elastic intermediate return lever 94.

A l'opposé de la griffe 93, il présente une gorge 95 pour son maintien sur des pattes d'accrochage non représentées prévues sur la goulotte 4 et le châssis (figure 1).Opposite the claw 93, it has a groove 95 for holding it on hooking lugs, not shown, provided on the chute 4 and the chassis (FIG. 1).

En regard des figures 1 à 3, on voit que les éléments du mécanisme de commande monté sur le bras 46 sont disposés en correspondance avec ceux du mécanisme d'entraînement monté sur l'arbre 40. Le bras 46 s'étend parallèlement à l'arbre 40, le doigt 45 et la griffe 93 étant disposés de manière sensiblement symétrique, par rapport au plan passant par les axes médians du bras 46 et de l'arbre 40, en ayant leurs extrémités recourbées l'une vers l'autre. La griffe 93 vient se positionner face à la portion annulaire dentée 84 de la partie 81 du bouton 43. Le doigt 45 vient se positionner devant le rouleau 35, en étant légèrement décalé de la face du rouleau pour s'insérer dans la goulotte 4 à une distance donnée du couteau égale à une longueur définie d'étiquettes. Le levier élastique de rappel 94, formé par une fine patte, présente latéralement un ergot semi-cylindrique 96 à son extrémité, cet ergot vient en appui sur le châssis du distributeur. Le levier assure le rappel de l'extrémité du doigt en obstacle dans la goulotte 4 en l'absence de ruban dans la goulotte.With reference to FIGS. 1 to 3, it can be seen that the elements of the control mechanism mounted on the arm 46 are arranged in correspondence with those of the drive mechanism mounted on the shaft 40. The arm 46 extends parallel to the shaft 40, the finger 45 and the claw 93 being arranged in a substantially symmetrical manner, with respect to the plane passing through the median axes of the arm 46 and of the shaft 40, having their ends curved towards one another. The claw 93 is positioned opposite the annular toothed portion 84 of the part 81 of the button 43. The finger 45 is positioned in front of the roller 35, being slightly offset from the face of the roller to be inserted in the chute 4 to a given distance from the knife equal to a defined length of labels. The elastic return lever 94, formed by a thin tab, laterally has a semi-cylindrical lug 96 at its end, this lug comes to bear on the frame of the dispenser. The lever recalls the end of the finger in obstacle in the chute 4 in the absence of ribbon in the chute.

Le fonctionnement du dispositif de chargement et de positionnement du ruban est le suivant.The operation of the tape loading and positioning device is as follows.

L'extrémité du ruban insérée dans l'entrée 5 du distributeur jusqu'au rouleau 25 est guidée le long de la goulotte 3 et dans la goulotte 4 par le rouleau 25 entraîné par le couplage à courroie 41 entre l'arbre 30 et l'arbre 40 par l'actionnement manuel en rotation du bouton 43.The end of the ribbon inserted in the inlet 5 of the distributor to the roller 25 is guided along the chute 3 and in the chute 4 by the roller 25 driven by the belt coupling 41 between the shaft 30 and the shaft 40 by manual actuation of the button 43 in rotation.

L'arrivée du bout du ruban contre l'extrémité du doigt 45 la fait basculer pour dégager la goulotte 4. Simultanément cet effacement du doigt 45 est transmis au bras 46 et provoque le basculement inverse de l'extrémité de la griffe 93 qui s'engage dans la denture de la portion annulaire 84 de la partie 81 du bouton 43, pour bloquer cette partie 81 et donc l'arbre 40 en rotation.The arrival of the end of the ribbon against the end of the finger 45 causes it to tilt to release the chute 4. Simultaneously this erasure of the finger 45 is transmitted to the arm 46 and causes the reverse tilting of the end of the claw 93 which s engages in the teeth of the annular portion 84 of the part 81 of the button 43, to block this part 81 and therefore the shaft 40 in rotation.

Dans ces conditions, le maintien de la commande manuelle sur le bouton 43, appliquée sur la partie terminale 82 plus accessible, n'est plus transmis à l'arbre 40. L'assemblage élastique des deux parties 81, 82 du bouton provoque alors le saut de la couronne crantée 86 de la partie 82 encore actionnée en rotation sur la couronne crantée 85 de la partie 81 alors bloquée. Le maintien de cette commande manuelle dès l'effacement du doigt, pour lequel l'extrémité du ruban est au dessus du doigt effacé, reste sans effet sur l'entraînement du ruban qui est alors considéré chargé et positionné convenablement dans la machine prête à fonctionner pour le prélèvement d'étiquettes sur le ruban.Under these conditions, the maintenance of the manual control on the button 43, applied to the terminal part 82 which is more accessible, is no longer transmitted to the shaft 40. The elastic assembly of the two parts 81, 82 of the button then causes the jump of the notched crown 86 of the part 82 still actuated in rotation on the notched crown 85 of the part 81 then blocked. Maintaining this manual control as soon as the finger is erased, for which the end of the ribbon is above the erased finger, has no effect on the entrainment of the ribbon which is then considered loaded and positioned properly in the machine ready for operation. for removing labels from the tape.

La présente invention a été décrite en regard de l'exemple de réalisation donné dans les dessins. Il est évident que l'on peut y apporter les modifications de détail et/ou remplacer certains moyens par d'autres moyens équivalents, sans pour autant sortir du cadre de cette invention.The present invention has been described with reference to the embodiment given in the drawings. It is obvious that one can make the modifications of detail and / or replace certain means by other equivalent means, without thereby departing from the scope of this invention.
