Description

La présente invention a pour objet un dispositif portable à commande manuelle destiné à permettre d'enrubanner des éléments quelconques, généralement de forme allongée ou courbe, tels que notamment des faisceaux de toute nature et plus particulièrement des faisceaux de câbles électriques, des barres, des tubes ou similaires destinés à tous domaines industriels et notamment à l'industrie automobile.The subject of the present invention is a portable device with manual control intended to allow wrapping of any elements, generally of elongated or curved shape, such as in particular bundles of any kind and more particularly bundles of electric cables, bars, tubes or the like intended for all industrial fields and in particular for the automobile industry.

Pour certaines applications, il est connu de réaliser des enrubannages de pièces et notamment de faisceaux de câbles totalement à la main. Cette solution est bien évidemment couteuse en raison de la main d'oeuvre qu'elle exige, son application entraînant un gaspillage de temps préjudiciable.For certain applications, it is known to make wrapping of parts and in particular of cable bundles completely by hand. This solution is obviously expensive because of the manpower it requires, its application resulting in a detrimental waste of time.

A l'heure actuelle cependant, on utilise de préférence pour l'enrubannage de telles pièces des machines comportant des têtes mobiles à déplacement mécanisé. Ces machines sont généralement encombrantes et nécessitent un déplacement devant la pièce mobile à enrubanner à travers la machine, elle-même déplacée vis à vis de la pièce maintenue, avec des supports généralement compliqués. De plus, si la pièce est fixe et la machine mobile, ces supports doivent être escamotés lors du passage de cette dernière.At present, however, machines with movable heads with mechanized movement are preferably used for wrapping such parts. These machines are generally bulky and require a displacement in front of the movable part to be wrapped through the machine, itself displaced with respect to the maintained part, with generally complicated supports. In addition, if the part is fixed and the machine mobile, these supports must be retracted during the passage of the latter.

On connaît également par le brevet US-A-4 346 550, une machine à enrubanner, portable, qui comporte une platine supportant un moteur d'entraînement ainsi que des moyens de commande de ce moteur et présentant un passage ouvert pour recevoir la pièce à enrubanner, une couronne rotative tournant sur la platine en étant commandée en rotation par le moteur par l'intermédiaire d'un moyen d'entraînement, la couronne comportant une ouverture dans laquelle s'engage la pièce à enrubanner lorsque cette ouverture coïncide avec le passage ouvert de la platine et au moins une bobine d'alimentation par le matériau souple en forme de ruban, bande ou cordon destiné à enrubanner la pièce, avec des moyens de renvoi et de guidage pour ce matériau.Also known from US-A-4,346,550 is a portable wrapping machine which comprises a plate supporting a drive motor as well as means for controlling this motor and having an open passage for receiving the part to be wrapping, a rotary crown rotating on the plate being controlled in rotation by the motor by means of a drive means, the crown comprising an opening in which the part to be wrapped engages when this opening coincides with the passage open of the plate and at least one supply coil by the flexible material in the form of a ribbon, strip or cord intended to wrap the part, with return and guide means for this material.

Or, ce dispositif connu présente encore des inconvénients. En particulier, la conception de la machine est telle qu'elle exige d'être tenue à deux mains par l'utilisateur, la platine étant munie à cet effet de deux poignées, ce qui exige que l'objet à enrubanner soit lui-­même guidé par des moyens complémentaires dont la présence rend difficile l'emploi de la machine, surtout si cet objet comporte une forme complexe. Notamment, le dispositif selon ce brevet américain antérieur ne peut en pratique que mettre en place un ruban sur un câble ou analogue, rectiligne ou sensiblement rectiligne, le long duquel la platine est alors déplacée par l'utilisateur. Par ailleurs, avec la machine connue par ce brevet antérieur, la mise en place du ruban sur l'objet à enrubanner ne peut se faire que selon une orientation qui reste constante, avec un angle prédéterminé sur l'axe de l'objet. De même, cette machine est conçue pour assurer une application du ruban avec une tension constante qui doit rester toujours égale à elle-même au fur et à mesure de la diminution du diamètre de la bobine délivrant le ruban. La machine exige de ce point de vue, des moyens de contrôle de la tension qui compliquent sa réalisation.However, this known device still has drawbacks. In particular, the design of the machine is such that it requires it to be held in both hands by the user, the plate being provided for this purpose with two handles, which requires that the object to be wrapped be itself guided by complementary means whose presence makes it difficult to use the machine, especially if this object has a complex shape. In particular, the device according to this prior American patent can in practice only put a ribbon on a cable or the like, straight or substantially straight, along which the plate is then moved by the user. Furthermore, with the machine known by this prior patent, the positioning of the ribbon on the object to be wrapped can only be done in an orientation which remains constant, with a predetermined angle on the axis of the object. Likewise, this machine is designed to ensure application of the ribbon with a constant tension which must always remain equal to itself as the diameter of the coil delivering the ribbon decreases. The machine requires from this point of view, tension control means which complicate its realization.

La présente invention a pour objet un appareil portable et mobile, à commande manuelle, mais à enrubannage automatique, qui permet de simplifier le processus de mise en place du ruban autour de la pièce à enrubanner et de réduire le coût d'une telle machine par comparaison aux divers systèmes actuellement utilisés pour enrubanner des faisceaux de câbles ou analogues. En particulier, la machine peut être mise en oeuvre pour enrubanner des câbles exécutés sur une planche ou un support du même genre avec un contrôle électrique permanent incorporé à ces câbles, l'enrubannage pouvant être effectué au niveau même de la planche, sans qu'il soit nécessaire de débrancher l'alimentation électrique du faisceau.The subject of the present invention is a portable and mobile device, with manual control, but with automatic wrapping, which makes it possible to simplify the process of placing the ribbon around the piece to be wrapped and to reduce the cost of such a machine by comparison to the various systems currently used for wrapping bundles of cables or the like. In particular, the machine can be used to wrap cables executed on a board or a similar support with a permanent electrical control incorporated in these cables, wrapping can be carried out at the same level of the board, without it is necessary to disconnect the electrical supply from the harness.

La machine selon l'invention présente également l'avantage de pouvoir suivre facilement le profil de la pièce ou objet à enrubanner, quel que soit celui-ci, en particulier s'il présente des coudes ou autres changements de direction, l'utilisateur pouvant tenir la machine d'une seule main et l'objet de l'autre, en adoptant en outre aussi fréquemment que nécessaire, des changements dans le sens de l'enroulement sans obliger un maintien de la tension du ruban nécessairement constante pendant toute l'opération d'enrubannage.The machine according to the invention also has the advantage of being able to easily follow the profile of the part or object to be wrapped, whatever it is, in particular if it has bends or other changes of direction, the user being able to hold the machine with one hand and the object with the other, while also adopting as frequently as necessary, changes in the direction of the winding without obliging the ribbon tension to be necessarily constant throughout the whole wrapping operation.

La machine selon l'invention peut être légère, facile à manipuler, en permettant un soutien permanent de la pièce par un guide convenablement aménagé prévu dans la couronne rotative, ce guide comportant des moyens propres à amener le ruban sur la pièce à enrubanner dans les meilleures conditions, indépendamment du sens de l'enroulement réalisé.The machine according to the invention can be light, easy to handle, allowing permanent support of the part by a suitably arranged guide provided in the rotary crown, this guide comprising means suitable for bringing the ribbon onto the part to be wrapped in the best conditions, regardless of the direction of winding carried out.

L'invention a en conséquence pour objet un dispositif portable et mobile à commande manuelle pour réaliser l'enrubannage d'une pièce telle que notamment un faisceau de câbles électriques avec un matériau souple, sous forme de ruban, bande ou cordon, dévidés à partir d'une bobine portée par le dispositif, celui-ci comportant une platine supportant un moteur d'entraînement ainsi que des moyens de commande de ce moteur, et présentant un passage ouvert pour recevoir la pièce, une couronne rotative tournant sur la platine en étant commandée en rotation par le moteur par l'intermédiaire d'un moyen d'entraînement, la couronne comprenant une ouverture dans laquelle s'engage la pièce à enrubanner lorsque cette ouverture coïncide avec le passage ouvert de la platine, et au moins une bobine d'alimentation avec le matériau souple avec des moyens de renvoi et de guidage pour ce matériau, caractérisé en ce que la couronne rotative comporte dans le fond de son ouverture recevant la pièce un guide incurvé pour positionner la pièce dans la couronne, une fente étant prévue dans le guide pour amener le matériau souple au contact de la pièce, ce guide comportant en outre à proximité de la fente, au moins deux rouleaux pour éviter le frottement du matériau tout en permettant son enroulement hélicoïdal sur la pièce, consécutivement à la rotation de la couronne et au déplacement manuel de la platine selon la longueur de cette pièce: ce qui permet de contrôler le pas et le sens d'enroulement sur celle-ci, la platine étant munie d'une poignée unique tenue par une main d'un utilisateur tandis que la pièce est guidée par l'autre main de celui-ci.The subject of the invention is therefore a portable and mobile device with manual control for carrying out the wrapping of a part such as in particular a bundle of electric cables with a flexible material, in the form of ribbon, strip or cord, unwound from a coil carried by the device, the latter comprising a plate supporting a drive motor as well as means for controlling this motor, and having an open passage for receiving the part, a rotary crown rotating on the plate being rotationally controlled by the motor via a drive means, the crown comprising an opening in which the part to be wrapped engages when this opening coincides with the open passage of the plate, and at least one coil d feeding with the flexible material with return and guide means for this material, characterized in that the rotary crown comprises in the bottom of its opening receiving the workpiece a curved guide for positioning the workpiece in the crown, a slot being provided in the guide for bringing the flexible material into contact with the workpiece, this guide further comprising near the slot, at least two rollers to avoid the friction of the material while allowing its helical winding on the part, following the rotation of the crown and the manual movement of the plate according to the length of this part: which makes it possible to control the pitch and the direction of winding on that -ci, the plate being provided with a single handle held by one hand of a user while the workpiece is guided by the other hand of the latter.

Selon les figures 1 à 3, on prévoit aussi des moyens de protection portés par la platine à l'entrée du passage recevant la pièce à enrubanner, ces moyens de protection étant réalisés de préférence sous la forme de volets, verrouillés en position de fermeture lors de la commande du moteur d'entraînement de la couronne rotative, et d'un capot protecteur de forme circulaire, de préférence transparent.According to Figures 1 to 3, there are also provided protective means carried by the plate at the entrance of the passage receiving the piece to be wrapped, these protective means being preferably produced in the form of flaps, locked in the closed position during the control of the drive motor of the rotary crown, and a protective cover of circular shape, preferably transparent.

Selon les figures 1 à 3, la poignée unique de préhension prévue sur la platine comporte également un système de double gâchette de commande du moteur, une première gâchette assurant la commande normale de la rotation de ce moteur pour réaliser l'enrubannage et une seconde gâchette assurant une commande progressive de la rotation, pour un déclenchement d'un cycle de repositionnement positif de la couronne rotative afin d'amener l'appareil en position d'ouverture c'est à dire dans une position faisant coïncider les passages respectifs de la platine et de la couronne rotative afin de faciliter l'introduction et l'extraction des pièces à enrubanner et des pièces enrubannées. Les deux gâchettes sont interverrouillées entre elles.According to FIGS. 1 to 3, the single grip handle provided on the plate also comprises a double trigger system for controlling the motor, a first trigger ensuring the normal control of the rotation of this motor to carry out the wrapping and a second trigger ensuring a progressive control of the rotation, for a triggering of a positive repositioning cycle of the rotary crown in order to bring the device into the open position, that is to say in a position making the respective passages of the plate coincide and of the rotary crown in order to facilitate the introduction and the extraction of the parts to be wrapped and of the wrapped parts. The two triggers are interlocked with each other.

Selon les figures 1 à 3, le système qui assure l'entraînement de la couronne mobile à l'aide du moteur est constitué d'une courroie sans fin pourvue d'un système tendeur du type pantin à action proportionnelle au couple résistant afin d'obtenir une tension de courroie réduite au minimum.According to FIGS. 1 to 3, the system which ensures the driving of the movable crown by means of the motor consists of an endless belt provided with a tensioning system of the puppet type with action proportional to the resisting torque in order to get belt tension reduced to a minimum.

Dans une autre variante, la poignée comporte deux gâchettes dont l'une agit par l'intermédiaire de butées de longueurs différentes sur les contacts d'un micro-relais, provoquant, selon le cas, l'entraînement du moteur à des vitesses constantes mais différentes.In another variant, the handle comprises two triggers, one of which acts by means of stops of different lengths on the contacts of a micro-relay, causing, as the case may be, the drive of the motor at constant speeds but different.

En variante également, la platine supporte un demi-capot fixe et un demi-capot mobile articulés sur la platine, les deux demi-capots étant rappelés en position d'appui l'un contre l'autre pour fermer le passage de la platine sous l'effet d'un ressort fixé à ses extrémités sur l'un et l'autre de ces demi-capots.Also in a variant, the plate supports a fixed half-cover and a movable half-cover articulated on the plate, the two half-covers being returned to the support position one against the other to close the passage of the plate under the effect of a spring fixed at its ends on both of these half-covers.

On se réfère tout d'abord, sur les dessins, plus particulièrement aux figures 1 et 2 qui illustrent un premier exemple de réalisation du dispositif objet de l'invention. Celui-ci comporte principalement une platine 10 munie d'une poignée unique 12, permettant à l'utilisateur la manoeuvre manuelle du dispositif sur ou vis à vis de la pièce à enrubanner de la manière qui sera explicitée plus loin. Sur cette platine 10 est monté un moteur d'entraînement 14, qui peut être pneumatique, électrique basse tension ou autre. Dans cet exemple, le moteur 14 est un moteur électrique qui entraîne un galet 20 d'axe 22 est et commandé par l'intermédiaire d'un système à double gâchette 30-32 actionnant une tige 34 permettant de faire varier la position d'un élément magnétique non représenté à l'intérieur d'une bobine 49 en modifiant le champ créé par celle-ci et par suite la vitesse du moteur 14 qui lui est associé. La gâchette 30 rappelée par un ressort assure le fonctionnement normal du moteur alors que la gâchette 32 est conçue de façon à commander le déclenchement d'un cycle de repositionnement relatif d'une couronne rotative portée par la platine, vis à vis de cette dernière, de la façon explicitée ci-après.First of all, reference is made to the drawings, more particularly to FIGS. 1 and 2 which illustrate a first embodiment of the device object of the invention. This mainly comprises a plate 10 provided with a single handle 12, allowing the user to manually operate the device on or with respect to the part to be wrapped in the manner which will be explained below. On this plate 10 is mounted a drive motor 14, which can be pneumatic, low voltage electric or other. In this example, the motor 14 is an electric motor which drives a roller 20 of axis 22 is and controlled by means of a double trigger system 30-32 actuating a rod 34 making it possible to vary the position of a magnetic element not shown inside a coil 49 by modifying the field created by it and consequently the speed of the motor 14 which is associated with it. The trigger 30 recalled by a spring ensures the normal operation of the motor while the trigger 32 is designed so as to control the triggering of a relative repositioning cycle of a rotary crown carried by the plate, with respect to the latter, as explained below.

Comme on le voit sur la figure 1, la gâchette 32 comporte un galet 36 venant appuyer sur un poussoir 37 monté sur la face frontale de la gâchette 30, ceci afin d'actionner le mécanisme faisant varier le champ dans la bobine 49, en permettant de modifier la vitesse du moteur 14. La platine 10 comporte par ailleurs un passage 13, ouvert à une extrémité pour permettre l'introduction et le positionnement d'une pièce à enrubanner dans le dispositif, cette pièce étant constituée ici par un faisceau de câbles C.As can be seen in FIG. 1, the trigger 32 comprises a roller 36 pressing on a plunger 37 mounted on the front face of the trigger 30, this in order to actuate the mechanism varying the field in the coil 49, allowing to modify the speed of the motor 14. The plate 10 also has a passage 13, open at one end to allow the introduction and positioning of a part to be wrapped in the device, this part being constituted here by a bundle of cables vs.

Sur cette platine 10 est montée, à l'aide de paliers appropriés (non représentés) une couronne rotative 16. Cette couronne est entraînée par le moteur 14 par l'intermédiaire d'une courroie 18 continue, fermée sur elle-même. Celle-ci est guidée à l'aide d'un ensemble de galets 28 tournant tous autour d'axes supportés par la platine et sa tension est réglée par l'intermédiaire d'un pantin oscillant 24 à deux galets 26, 27, monté sur l'axe 22 du galet d'entraînement 20. Grâce à ce dispositif tendeur de courroie, dont l'action est proportionnelle au couple résistant, il est notamment possible d'obtenir une tension de courroie particulièrement réduite sans nuire à l'efficacité de l'entraînement qu'elle procure pour la couronne rotative, ce qui permet de minimiser les bruits de fonctionnement ainsi que l'usure de la courroie. En outre, ce montage permet grâce à sa souplesse d'absorber la différence de parcours de la courroie 18, qui est du à la présence d'une ouverture en forme de fente 15 également prévue dans la couronne circulaire 16 pour l'introduction de la pièce C. Cette ouverture 15 correspond au passage 13 prévu dans la platine 10. Elle est pourvue dans son fond d'un guide incurvé 62, solidaire de la couronne. En outre, et conformément à l'invention, afin de permettre en toutes circonstances un positionnement précis de la pièce C lors du fonctionnement du dispositif, ce guide 62 comporte de préférence une branche de longueur plus importante que l'autre, comme on peut le voir sur la figure 2.On this plate 10 is mounted, using appropriate bearings (not shown) a rotary crown 16. This crown is driven by the motor 14 via a continuous belt 18, closed on itself. This is guided using a set of rollers 28 all rotating around axes supported by the plate and its tension is adjusted by means of an oscillating dancer 24 with two rollers 26, 27, mounted on the axis 22 of the drive roller 20. Thanks to this belt tensioning device, the action of which is proportional to the resisting torque, it is in particular possible to obtain a particularly reduced belt tension without harming the efficiency of the drive it provides for the rotating crown, which minimizes operating noise and wear on the belt. In addition, this assembly allows, thanks to its flexibility, to absorb the difference in the path of the belt 18, which is due to the presence of a slot-shaped opening 15 also provided in the circular crown 16 for the introduction of the piece C. This opening 15 corresponds to the passage 13 provided in the plate 10. It is provided at its bottom with a curved guide 62, integral with the crown. In addition, and in accordance with the invention, in order to allow in all circumstances precise positioning of the part C during the operation of the device, this guide 62 preferably comprises one branch of greater length than the other, as can be see in figure 2.

Sur la couronne rotative 16 est monté un support 50 pour réaliser l'alimentation en ruban, cordon ou similaire, d'un matériau souple, destiné à enrubanner la pièce C. Ce ruban b est conditionné sous la forme d'une bobine B maintenue sur le support 50 tournant avec la couronne 16 au moyen d'un ensemble comprenant d'une part un galet à gradins 52 et d'autre part un arbre 54 monté à l'extrémité d'un bras oscillant 56. L'entre-axe du galet 52 et de l'arbre 54 est ainsi variable, de manière à permettre le montage de bobines b de diamètres différents, le galet à gradins 52 pouvant en outre recevoir des bobines de largeurs également différentes. Le ruban b dévidé de la bobine B passe successivement sur un galet 58 cylindrique puis sur un autre galet 60, ayant avantageusement un profil en diabolo de manière à permettre, selon l'orientation relative du dispositif par rapport à la pièce C, un changement d'orientation du sens d'enroulement du ruban b sur cette pièce, au gré de l'utilisateur, notamment au fur et à mesure que celui-ci, tenant d'une main le dispositif par la poignée 12 et la pièce C avec l'autre main, oriente l'un par rapport à l'autre en suivant la pièce et le contour de cette dernière. Avantageusement, la machine comporte sur le trajet du ruban b, entre les galets 58 et 60 un frein mécanique 59, régularisant le défilement du ruban. Celui-ci à la sortie du galet 60 en diabolo, est amené au contact de la pièce C après passage au travers d'une fente étroite 64 prévue dans le guide 62, cette fente 64 étant associée à son voisinage immédiat à deux rouleaux 66 dont le but est d'éviter tout frottement entre le ruban b et les surfaces en regard de la fente, ce qui permet d'éliminer tout risque de détérioration du ruban par les arêtes de cette dernière.On the rotary ring 16 is mounted a support 50 for supplying ribbon, cord or the like, with a flexible material, intended to wrap the part C. This ribbon b is packaged in the form of a reel B held on the support 50 rotating with the crown 16 by means of an assembly comprising on the one hand a step roller 52 and on the other hand a shaft 54 mounted at the end of an oscillating arm 56. The center distance of the roller 52 and shaft 54 is thus variable, so as to allow the mounting of coils b of different diameters, the step roller 52 can also receive coils of also different widths. The ribbon b unwound from the reel B passes successively over a cylindrical roller 58 then over another roller 60, advantageously having a diabolo profile so as to allow, according to the relative orientation of the device with respect to the part C, a change d orientation of the direction of winding of the ribbon b on this piece, at the option of the user, in particular as the latter, holding the device with one hand by the handle 12 and the piece C with the other hand, orient relative to each other by following the part and the outline of the latter. Advantageously, the machine comprises on the path of the ribbon b, between the rollers 58 and 60 a mechanical brake 59, regulating the movement of the ribbon. The latter at the outlet of the roller 60 in diabolo, is brought into contact with the part C after passage through a narrow slot 64 provided in the guide 62, this slot 64 being associated with its immediate vicinity with two rollers 66 whose purpose is to avoid any friction between the ribbon b and the surfaces facing the slot, which makes it possible to eliminate any risk of deterioration of the ribbon by the edges of the latter.

Le dispositif comporte par ailleurs un système de coupe du ruban constitué par une lame 61, montée sur une glissière 63 rappelée par un ressort 65, la lame pénétrant dans une fente 67 du guide 62 pour assurer la coupe du ruban en fin d'enrubannage de la pièce C à l'arrêt de la couronne.The device also comprises a ribbon cutting system consisting of a blade 61, mounted on a slide 63 returned by a spring 65, the blade penetrating into a slot 67 of the guide 62 to ensure the cutting of the ribbon at the end of wrapping of piece C at the stop of the crown.

Egalement, le dispositif comporte des moyens de protection de l'utilisateur, notamment lors de l'enrubannage de la pièce C. Dans l'exemple de réalisation considéré sur les figures 1 et 2, ces moyens consistent en deux doubles volets, respectivement 39 et 41, articulés sur la platine 10 par des biellettes 38 et 40 formant avec les volets deux parallélogrammes déformables. Ces volets 39 et 41 sont disposés au travers du passage 13 et de l'ouverture 15 respectivement de la platine et de la couronne 16, de telle sorte que, en position écartée consécutivement au pivotement des biellettes 38 et 40, ils libèrent le passage pour la pièce C lorsque la fente et l'ouverture coïncident mutuellement. Après l'introduction de la pièce, les volets sont ramenés en position rapprochée l'un de l'autre où ils enferment la pièce, les volets étant dans cette position verrouillés l'un contre l'autre. A cet effet, le dispositif comporte une tige 44 actionnée par un renvoi commandé par le système à double gâchette 30-32 commandant la rotation du moteur 14, l'extrémité de la tige 44 venant s'engager pour le blocage des volets 39 et 41 dans une fente 42 prévue sur l'une des biellettes 40 d'articulation de ces volets.Also, the device comprises means for protecting the user, in particular during the wrapping of the part C. In the embodiment considered in FIGS. 1 and 2, these means consist of two double flaps, respectively 39 and 41, articulated on the plate 10 by links 38 and 40 forming with the flaps two deformable parallelograms. These flaps 39 and 41 are arranged through the passage 13 and the opening 15 respectively of the plate and the crown 16, so that, in the position spaced apart following the pivoting of the links 38 and 40, they free the passage for the part C when the slot and the opening coincide mutually. After the introduction of the part, the flaps are returned to the position close to one another where they enclose the part, the flaps being in this position locked against one another. To this end, the device comprises a rod 44 actuated by a reference controlled by the double trigger system 30-32 controlling the rotation of the motor 14, the end of the rod 44 engaging to block the flaps 39 and 41 in a slot 42 provided on one of the links 40 for articulation of these flaps.

Sur la figure 2 également, on a schématiquement représenté un capot protecteur transparent 71 susceptible d'être mis en place autour du dispositif une fois celui-ci prêt à fonctionner, la pièce C étant dans ce cas introduite et enfermée à l'intérieur du guide incurvé 62.Also in FIG. 2, a transparent protective cover 71 has been shown diagrammatically capable of being placed around the device once it is ready to operate, the part C being in this case introduced and enclosed inside the guide. curved 62.

Dans l'exemple de réalisation représenté, les deux gâchettes 30 et 32 sont de préférence interconnectées mutuellement à l'aide d'un montage du genre goupille-fente non représenté sur le dessin. D'autres dispositions annexes peuvent être également envisagées, par exemple ; ainsi, bien que le dispositif présente un poids réduit en raison de sa conception très simple, il peut être suspendu à l'aide d'un système équilibreur classique, réuni à une potence mobile, afin de couvrir l'ensemble de la zone où il doit être mis en oeuvre. Un bouton d'arrêt d'urgence 46 est monté sur la platine 10, de préférence dans une position où il peut être actionné par le haut du poignet de l'utilisateur avec la main qui tient la poignée, ce bouton 46 commandant l'arrêt immédiat du moteur 14.In the embodiment shown, the two triggers 30 and 32 are preferably mutually interconnected using an assembly of the pin-slot type not shown in the drawing. Other ancillary provisions can also be envisaged, for example; thus, although the device has a reduced weight due to its very simple design, it can be suspended using a conventional balancing system, combined with a movable bracket, in order to cover the entire area where it must be implemented. An emergency stop button 46 is mounted on the plate 10, preferably in a position where it can be actuated by the top of the user's wrist with the hand holding the handle, this button 46 controlling the stop engine 14.

Le fonctionnement du dispositif à travers la variante de réalisation illustrée sur les figures 1 à 3 ci-dessus est le suivant :The operation of the device through the alternative embodiment illustrated in Figures 1 to 3 above is as follows:

L'utilisateur qui maintient le dispositif dans l'une de ses mains à l'aide de la poignée 12, actionne dans un premier temps la gâchette 32 afin de déclencher le moteur 14 pour la commande d'un cycle préliminaire de repositionnement, amenant la fente 13 et l'ouverture 15 respectivement de la platine 10 et de la couronne rotative 16, en coïncidence, ceci pour permettre l'introduction dans le dispositif de la pièce C à travers les volets 39 et 41 convenablement écartés. Une fois la pièce mise en place, la gâchette 32 n'est plus utilisée, la tige 44 étant ramenée dans une position où, par son extrémité elle s'engage dans la fente 42 en bloquant l'un contre l'autre les volets, la pièce C restant emprisonnée derrière ceux-ci contre le fond incurvé 62.The user who holds the device in one of his hands using the handle 12, first activates the trigger 32 in order to trigger the motor 14 for the control of a preliminary repositioning cycle, bringing the slot 13 and the opening 15 respectively of the plate 10 and the rotary crown 16, in coincidence, this to allow the introduction into the device of the part C through the flaps 39 and 41 suitably spaced. Once the part has been put in place, the trigger 32 is no longer used, the rod 44 being brought back into a position where, by its end, it engages in the slot 42 by blocking the flaps against one another, the part C remaining trapped behind them against the curved bottom 62.

L'utilisateur actionne ensuite la gâchette 30, ce qui commande la rotation progressive du moteur 14, par variation du champ créé dans la bobine 49. Le moteur 14 entraîne alors en rotation la couronne mobile 16 par l'intermédiaire de la courroie 18, cette rotation de la couronne étant corrélativement transmise au support 50 de la bobine d'alimentation B. Le ruban b dévidé de cette bobine, convenablement guidé par les rouleaux 58 et 60 et introduit dans le guide 62 à travers la fente 64, peut alors être enroulé sur la pièce C que l'utilisateur tient par son autre main, en permettant ainsi de suivre facilement le profil de la pièce avec l'appareil, notamment en réalisant chaque fois que nécessaire une variation du sens d'enroulement sur la pièce, vers la droite ou vers la gauche, avec un angle plus ou moins accentué. Ces variations sont rendues possibles par la mise en oeuvre simultanée du galet en forme de diabolo 60, et d'un ensemble conçu de telle sorte que, tenant le dispositif d'une seule main, l'utilisateur peut aisément en modifier l'inclinaison relative vis à vis de la pièce. A noter que, au cours de ce mouvement et quelle que soit l'orientation du ruban, celui-ci est guidé à la traversée de la fente étroite 64 lors de son entrée dans le guide incurvé 62 par les rouleaux 66. Le dispositif selon l'invention peut donc enrubanner toute forme de pièce sans qu'il soit nécessaire de procéder à une coupure du ruban et à une reprise de l'enrubannage comme c'est le cas avec les machines classiques.The user then actuates the trigger 30, which controls the progressive rotation of the motor 14, by variation of the field created in the coil 49. The motor 14 then rotates the movable crown 16 via the belt 18, this rotation of the crown being correlatively transmitted to the support 50 of the supply reel B. The ribbon b unwound from this reel, suitably guided by the rollers 58 and 60 and introduced into the guide 62 through the slot 64 can then be rolled up on the part C which the user holds with his other hand, thus making it possible to easily follow the profile of the part with the apparatus, in particular by performing, whenever necessary, a variation of the direction d 'winding on the part, to the right or to the left, with a more or less accentuated angle. These variations are made possible by the simultaneous use of the diabolo-shaped roller 60, and of an assembly designed so that, holding the device with one hand, the user can easily modify the relative inclination opposite the room. Note that, during this movement and whatever the orientation of the ribbon, it is guided through the narrow slot 64 when it enters the curved guide 62 by the rollers 66. The device according to the he invention can therefore wrap any shape of part without the need to cut the ribbon and resume wrapping as is the case with conventional machines.

Avantageusement et pour réduire les frottements de la pièce C dans le fond du guide 62, celui-ci est réalisé en un matériau à faible coefficient de frottement, par exemple en bronze ou en tout autre matériau recouvert d'une pellicule plastique du genre "Teflon" ou autre ; en outre le guide 62 présente de préférence une section légèrement bombée vers l'extérieur.Advantageously and to reduce the friction of the part C in the bottom of the guide 62, the latter is made of a material with a low coefficient of friction, for example bronze or any other material covered with a plastic film of the "Teflon" type. " Or other ; further, the guide 62 preferably has a slightly curved outward section.

Grâce à sa conception, l'appareil peut aussi être réalisé de telle sorte que son fonctionnement soit unidirectionnel mais en autorisant, grâce à un retournement de 180° obtenu par exemple à l'aide d'un anneau de rotation, un changement de la direction d'enrubannage, le ruban dans chaque cas étant enroulé sur la pièce selon une hélice unique, de préférence à pas constant. Dans ce cas, la platine peut comporter deux poignées de commande symétriques l'une de l'autre mais jouant alternativement le rôle d'une poignée unique.Thanks to its design, the device can also be made in such a way that its operation is unidirectional but by authorizing, thanks to a 180 ° reversal obtained for example using a rotation ring, a change of direction wrapping, the ribbon in each case being wound on the part according to a single helix, preferably at constant pitch. In this case, the plate may include two control handles that are symmetrical to one another but alternately playing the role of a single handle.

Parmi les avantages procurés par le dispositif, on peut noter, du fait de la simplicité des moyens qu'il met en oeuvre, un poids réduit joint à une interchangeabilité rapide de la bobine d'alimentation en matériau souple d'enrubannage. L'appareil est facile à utiliser et permet une pose simple et rapide du ruban sur la pièce, quelque soit le profil de cette dernière. Le dispositif est enfin conçu pour procurer une grande sécurité d'emploi du fait du capot de protection, du système de commande à double gâchette et du bouton d'arrêt d'urgence qu'il comporte.Among the advantages provided by the device, it may be noted, due to the simplicity of the means which it implements, a reduced weight combined with rapid interchangeability of the supply reel in flexible wrapping material. The device is easy to use and allows simple and quick installation of the ribbon on the part, whatever the profile of the latter. The device is finally designed to provide great security of use because of the protective cover, the double trigger control system and the emergency stop button which it comprises.

Les figures 4 à 6 illustrent une autre variante de réalisation du dispositif considéré sur lesquelles on a repris des chiffres de référence indentiques pour désigner les mêmes organes. On retrouve ainsi la platine 10, la poignée de préhension 12, le moteur d'entraînement 14, le courroie 18 avec ses poulies de guidage 20, 26, 27, 28, la couronne rotative 16 et le guide incurvé 62 associé à cette dernière. Egalement, apparaissent sur ces figures le passage 13 dans la platine et l'ouverture 15 dans la couronne 16, ainsi que la pièce C à enrubanner avec le ruban b provenant de la bobine B.FIGS. 4 to 6 illustrate another alternative embodiment of the device considered, on which identical reference numbers have been used to designate the same members. We thus find the plate 10, the grip handle 12, the drive motor 14, the belt 18 with its guide pulleys 20, 26, 27, 28, the rotary crown 16 and the curved guide 62 associated with the latter. Also, appear in these figures the passage 13 in the plate and the opening 15 in the crown 16, as well as the part C to be wrapped with the ribbon b coming from the reel B.

Dans cet exemple de réalisation, la commande du dispositif est à nouveau réalisée au moyen d'un système à double gâchette 30-32. Toutefois, dans ce cas, le mode de commande du moteur est différent, de même que l'aménagement des moyens qui permettent le repositionnement initial de la couronne vis à vis de la platine lors de l'introduction de la pièce C.In this exemplary embodiment, the device is again controlled by means of a double trigger system 30-32. However, in this case, the engine control mode is different, as is the arrangement of the means which allow the initial repositioning of the crown with respect to the plate during the introduction of the part C.

La gâchette 32 est ainsi articulée autour d'un axe de pivotement 80 et comporte un retour 82. Un ressort 84 est monté entre la gâchette 32 et le fond en regard de la poignée 12, le pivotement de la gâchette à l'encontre de ce ressort pouvant s'effectuer jusqu'à appui sur une tige de butée 88. La gâchette est repoussée dans le sens correspondant par le doigt de l'utilisateur engagé dans l'espace 83 prévu entre les deux gâchettes 30 et 32. Dans ce mouvement, le retour 82 comprime un autre ressort 90 qui agit sur une tige ou barette transversale 92, comportant à son extrémité une extension formant bec 93, propre à s'engager dans un logement 94 prévu dans la couronne rotative 16 pour immobiliser cette dernière, notamment lorsque l'ouverture 15 de celle-ci coïncide avec le passage 13 de la platine. Sur la gâchette 32 est également articulée une tige 96 prolongeant un poussoir 97, réuni par un ressort 98 à platine. La tige 92 est elle-même montée mobile autour d'un axe 91 de telle sorte que son pivotement, cette fois à l'encontre du ressort 90, permette de dégager le bec 93 du logement 94 en libérant la couronne 16. L'embout 97 comporte un oeilleton 99 dans lequel se débat un pion 100 porté par la seconde gâchette 30. Celle-ci comporte comme la première un retour 102 et est articulée sur la platine autour d'un axe 103. Elle est par ailleurs munie de deux butées respectivement 104 et 106 de longueurs différentes comme illustré sur la figure 4, ces butées permettant d'agir selon la position de la gâchette 30 sur le contact mobile 108 d'un micro-relais 110 monté à l'intérieur de la poignée 12. Sur le retour 108 de la gâchette 30 est prévue une butée 112, un mécanisme de rappel élastique 114 et enfin un ressort 116.The trigger 32 is thus articulated around a pivot axis 80 and has a return 82. A spring 84 is mounted between the trigger 32 and the bottom opposite the handle 12, the pivoting of the trigger against this spring capable of being carried out until it rests on a stop rod 88. The trigger is pushed in the corresponding direction by the user's finger engaged in the space 83 provided between the two triggers 30 and 32. In this movement, the return 82 compresses another spring 90 which acts on a transverse rod or bar 92, having at its end an extension forming a spout 93, suitable for engaging in a housing 94 provided in the rotary crown 16 to immobilize the latter, in particular when the opening 15 of the latter coincides with the passage 13 of the plate. On the trigger 32 is also articulated a rod 96 extending a pusher 97, joined by a spring 98 with platinum. The rod 92 is itself movably mounted around an axis 91 so that its pivoting, this time against the spring 90, allows the spout 93 to be released from the housing 94 by releasing the crown 16. The end piece 97 comprises an eyelet 99 in which a pin 100 carried by the second trigger 30 is struggling. The latter comprises, like the first, a return 102 and is articulated on the plate around an axis 103. It is moreover provided with two stops respectively 104 and 106 of different lengths as illustrated in FIG. 4, these stops making it possible to act according to the position of the trigger 30 on the movable contact 108 of a micro-relay 110 mounted inside the handle 12. On the return 108 of the trigger 30 is provided with a stop 112, an elastic return mechanism 114 and finally a spring 116.

Le fonctionnement du système à double gâchette est dans cette seconde variante de réalisation le suivant : par action sur la gâchette 32, l'utilisateur exerce sur le ressort 90 un effort repoussant la tige 92 et en même temps qu'il commande à vitesse lente la rotation du moteur 14 jusqu'à ce que, pour la position de la couronne 16 où son ouverture 15 coïncide avec le passage 13, le bec 93 tombe dans le logement 94 en immobilisant la couronne.The operation of the double trigger system is in this second variant embodiment as follows: by acting on the trigger 32, the user exerts on the spring 90 a force pushing the rod 92 and at the same time that he controls at low speed the rotation of the motor 14 until, for the position of the crown 16 where its opening 15 coincides with the passage 13, the spout 93 falls into the housing 94 while immobilizing the crown.

A cet instant, l'utilisateur relâche son effort sur la gâchette 32 et, après que la pièce C ait été mise en place dans le guide incurvé 62 peut commander la rotation normale de la couronne et l'enrubannage de la pièce par le ruban b de la manière déjà décrite en relation avec le premier exemple de réalisation. Dans ce cas, cependant, l'action de la gâchette 30 sur la commande du moteur est non plus progressive mais réalisée à deux vitesses distinctes, respectivement lente et plus rapide selon les besoins.At this instant, the user releases his effort on the trigger 32 and, after the part C has been placed in the curved guide 62 can control the normal rotation of the crown and the wrapping of the part by the ribbon b in the manner already described in relation to the first exemplary embodiment. In this case, however, the action of the trigger 30 on the motor control is no longer progressive but carried out at two separate speeds, respectively slow and faster as required.

A cet effet, la gâchette 30, en pivotant sous l'effet du doigt de l'utilisateur autour de son axe 103, provoque par la butée 112, un effet de retrait du bec 93, en faisant tourner légèrement la tige 92 sur son axe 91. Simultanément la gâchette 30 appuie par la première butée 104 sur le contact 108 et par le micro-relais 110 ferme l'alimentation du moteur 14 entraîné à vitesse lente, par exemple. Si l'utilisateur poursuit son effort sur la gâchette 30, c'est la seconde butée 110 qui vient fermer un second contact 107 sur le micro-relais, le moteur 14 tournant alors à vitesse plus élevée. A noter que la présence du dispositif de rappel élastique 114 permet à l'utilisateur de percevoir au toucher une séparation nette entre les deux modes de fonctionnement et de réaliser l'entraînement à vitesse plus élevée du moteur uniquement après franchissement de la résistance opposée à la gâchette par ce dispositif 114. La butée 112 aide au basculement de la tige 92, le ressort 116 permettant pour sa part un effort de rappel permanent sur la gâchette 30 dès que l'utilisateur libère cette dernière.To this end, the trigger 30, by pivoting under the effect of the user's finger around its axis 103, causes by the stop 112, an effect of withdrawal of the spout 93, by slightly rotating the rod 92 on its axis 91. Simultaneously the trigger 30 presses by the first stop 104 on the contact 108 and by the micro-relay 110 closes the supply of the motor 14 driven at low speed, for example. Yes the user continues his effort on the trigger 30, it is the second stop 110 which closes a second contact 107 on the micro-relay, the motor 14 then rotating at higher speed. Note that the presence of the elastic return device 114 allows the user to perceive by touch a clear separation between the two operating modes and to carry out the drive at higher speed of the motor only after crossing the resistance opposite to the trigger by this device 114. The stop 112 assists in the tilting of the rod 92, the spring 116 allowing for its part a permanent return force on the trigger 30 as soon as the user releases the latter.

Avantageusement et dans la variante illustrée sur ces figures, la poignée de préhension 12 du dispositif est creuse et comporte les organes de connection électriques nécessaires à la commande du moteur 14. La référence 122 schématise le fil de liaison réunissant dans ce cas l'appareil à une source de tension extérieure non représentée. En variante, on peut monter à l'intérieur de la poignée une batterie 120 elle-même raccordée en période de non utilisation de l'appareil à un chargeur classique, de manière à assurer une autonomie de fonctionnement du dispositif sans qu'il soit nécessaire dans ce cas de le réunir par un fil à une source extérieure, ce qui peut présenter dans certains cas un avantage particulièrement apprécié.Advantageously and in the variant illustrated in these figures, the grip handle 12 of the device is hollow and comprises the electrical connection members necessary for controlling the motor 14. The reference 122 shows diagrammatically the connecting wire joining in this case the device to an external voltage source not shown. Alternatively, one can mount inside the handle a battery 120 itself connected during periods of non-use of the device to a conventional charger, so as to ensure autonomy of operation of the device without it being necessary in this case to join it by a wire to an external source, which can present in certain cases a particularly appreciated advantage.

Dans l'exemple illustré sur les figures 4 à 6, le couteau 61 réalisant le sectionnement du ruban en fin d'enrubannage est monté dans une position différente de celle représentée dans l'exemple des figures 1 à 3. Ce couteau 61 est ici articulé sur un levier 124 pivotant autour d'un axe 126, celui-ci comportant une enclûme 127 sur laquelle peut venir exercer un effort dirigé vers le bas obtenu par un poinçon 128 lui-même apte à être actionné par un bouton 130, à commande dite "coup de poing". Le bouton 130 est soumis à l'action d'un ressort 132 le rappelant en permanence dans une position où le couteau 61 est relevé et extérieur au guide incurvé 62.In the example illustrated in FIGS. 4 to 6, the knife 61 carrying out the cutting of the ribbon at the end of wrapping is mounted in a position different from that represented in the example of FIGS. 1 to 3. This knife 61 is here articulated on a lever 124 pivoting about an axis 126, the latter comprising an anvil 127 on which can exert a downwardly directed force obtained by a punch 128 itself capable of being actuated by a button 130, with so-called control "punch". The button 130 is subjected to the action of a spring 132 permanently recalling it to a position where the knife 61 is raised and outside the curved guide 62.

Dans cette même variante, le guide 62 comporte un ensemble de quatre rouleaux 66 avantageusement montés à l'extérieur du guide dans des ouvertures de celui-ci de telle sorte qu'ils affleurent légèrement vers l'intérieur pour faciliter le support et le soutien de la pièce C lors de l'opération d'enrubannage. Bien entendu, ces dispositions sont mises en oeuvre en même temps que celles déjà prévues dans la première variante, avec en particulier la fente 64 traversée par le ruban b, le cas échéant avec la forme bombée du guide du bronze ou autre et son revêtement éventuel d'un matériau plastique. Par ailleurs, dans ce cas comme précédemment, le ruban b en passant sur le galet 60 en forme de diabolo peut voir son orientation modifiée à la demande, au gré de l'utilisateur qui peut selon la situation, les besoins et la position relative du dispositif par rapport à la pièce, modifier le sens d'enroulement et l'angle de l'hélice formée.In this same variant, the guide 62 comprises a set of four rollers 66 advantageously mounted on the outside of the guide in openings of the latter so that they are slightly flush inwards to facilitate the support and the support of part C during the wrapping operation. Of course, these arrangements are implemented at the same time as those already provided for in the first variant, with in particular the slot 64 traversed by the ribbon b, where appropriate with the convex shape of the bronze guide or the like and its possible coating. of a plastic material. Furthermore, in this case as before, the ribbon b passing over the roller 60 in the form of a diabolo can see its orientation modified on demand, at the discretion of the user who can, depending on the situation, the needs and the relative position of the device in relation to the part, modify the winding direction and the angle of the propeller formed.

Dans l'exemple illustré sur les figures 4 à 6, la machine comporte par ailleurs un dispositif de protection de l'utilisateur et de verrouillage du passage 13 prévu dans la platine, une fois la pièce à enrubanner mise en place, dont la structure est différente de celle adoptée dans la variante précédente.In the example illustrated in FIGS. 4 to 6, the machine also comprises a device for protecting the user and for locking the passage 13 provided in the plate, once the piece to be wrapped in place, the structure of which is different from that adopted in the previous variant.

Dans ce cas, la platine 10 comporte un axe 134 autour duquel est articulé un capot 135 en forme de demi-coupelle, et agencé pour se débattre en regard d'un capot fixe similaire 136. Le capot fixe et le capot mobile sont réunis l'un à l'autre par un ressort de rappel 137 dont les extrémités sont respectivement fixées sur deux pions 138, 139 appartenant à chacun de ces capots, ce ressort permettant en position de verrouillage où les capots sont rapprochés l'un de l'autre de fermer le passage 13 de la platine et l'ouverture 15 de la couronne grâce notament à un galet d'appui 140 tournant autour d'un axe 142 sur une chape 144 prévue en bout du capot mobile 135. Lorsque celui-ci est ouvert, le ressort 137 est tel qu'il se place de l'autre côté de l'axe 134 en exerçant sur le capot un effort maintenant celui-ci écarté. Un micro-contact 146 permet dans cette position d'ouverture du capot mobile de couper l'alimentation du moteur 14 qui ne peut fonctionner au contraire ou une fois le capot ramené dans sa position de fermeture.In this case, the plate 10 has an axis 134 around which a cover 135 in the form of a half-cup is articulated, and arranged to struggle opposite a similar fixed cover 136. The fixed cover and the movable cover are joined together. '' to one another by a return spring 137, the ends of which are respectively fixed on two pins 138, 139 belonging to each of these covers, this spring allowing in the locked position where the covers are brought closer to each other to close the passage 13 of the plate and the opening 15 of the crown thanks in particular to a support roller 140 rotating around an axis 142 on a yoke 144 provided at the end of the movable cover 135. When the latter is open , the spring 137 is such that it is placed on the other side of the axis 134 by exerting on the cover a force keeping the latter apart. A microswitch 146 makes it possible in this open position of the movable cover to cut off the supply to the motor 14 which cannot operate on the contrary or once the cover is returned to its closed position.

Sur les figures 4 et 5, on a enfin illustré une modification apportée au bouton d'arrêt d'urgence constitué dans ce cas par une languette 46 articulée sur la poignée, à l'encontre d'un ressort 47 et permettant en cas de basculement de venir également arrêter l'alimentation du moteur par un micro-contact complémentaire 48.FIGS. 4 and 5 finally illustrate a modification made to the emergency stop button constituted in this case by a tongue 46 articulated on the handle, against a spring 47 and allowing in the event of tilting also to stop the power supply to the motor by an additional micro-contact 48.
