- the adhesive applicator element also consists of a roller mounted to rotate on an axis carried by the housing, while the pusher consists of a simple button emerging from the housing.
- the button and the roller are located at the two ends of the front face of the case, while on the other device, these two members are located respectively one on and the other under the case.
- the role of the pusher is provided by a pivoting handle on one side of the housing and the adhesive applicator element is constituted by the supplying coil itself, the periphery of which emerges from below the housing.

Description
La présente invention a pour objet un appareil portatif pour l'application d'adhésif-transfert sur un objet à encoller dans le but soit de fixer cet objet sur un autre soit d'y fixer un autre objet par pression de contact.The present invention relates to a portable device for applying adhesive transfer to an object to be bonded for the purpose of either fixing this object on another or fixing another object there by contact pressure.
Cet appareil est du genre comprenant un boîtier ouvrable, une bobine débitrice montée à rotation dans le boîtier, un ruban porteur d'un film d'adhésif détachable enroulé autour de la bobine débitrice, une bobine réceptrice montée à rotation dans le boîtier au voisinage de la bobine débitrice, une transmission de mouvements rotatifs entre la bobine débitrice et la bobine réceptrice pour le réenroulement synchrone du ruban autour de la bobine réceptrice, un frein d'immobilisation de la rotation de la bobine débitrice, un poussoir à rappel élastique de commande d'actionnement du frein dont une partie est disposée en saillie hors du boîtier, et sur lequel boîtier un élément applicateur d'adhésif est prévu, autour duquel est passé le ruban et qui est destiné à être appuyé sur un objet à encoller par transfert du film porté par le ruban.This device is of the type comprising an openable casing, a take-up reel mounted for rotation in the case, a tape carrying a film of detachable adhesive wound around the feed reel, a take-up reel mounted for rotation in the case near the take-up reel, a transmission of rotary movements between the take-up reel and the take-up reel for the synchronous rewinding of the tape around the take-up reel, a brake for immobilizing the rotation of the take-up reel, a push button with elastic return control actuation of the brake, part of which is projecting from the housing, and on which housing an adhesive applicator element is provided, around which the tape is passed and which is intended to be pressed on an object to be glued by transfer of the film carried by the ribbon.
Les appareils de ce genre qui se trouvent sur le marché sont différenciés, entre autres, par la nature et les emplacements relatifs du pousoir et de l'élément applicateur d'adhésif sur le boîtier.Apparatuses of this kind which are on the market are differentiated, among other things, by the nature and the relative locations of the plunger and of the adhesive applicator element on the case.
Sur l'un de ces appareils connus, le poussoir est constitué par la gâchette d'une poignée située d'un côté du boîtier et faisant corps avec celui-ci, et l'élément applicateur d'adhésif est constitué par un rouleau monté rotatif sur un axe porté en bout d'une avancée du dessous du boîtier.On one of these known devices, the pusher is constituted by the trigger of a handle situated on one side of the casing and integral with it, and the adhesive applicator element is constituted by a roller mounted to rotate on an axis carried at the end of a projection from below the housing.
Sur deux autres appareils connus, l'élément applicateur d'adhésif est également constitué par un rouleau monté rotatif sur un axe porté par le boîtier, alors que le poussoir est constitué par un simple bouton émergeant du boîtier. Sur l'un de ces deux appareils le bouton et le rouleau sont situés aux deux extrémités de la face avant du boîtier alors que sur l'autre appareil ces deux organes sont situés respectivement l'un sur et l'autre sous le boîtier.On two other known devices, the adhesive applicator element also consists of a roller mounted to rotate on an axis carried by the housing, while the pusher consists of a simple button emerging from the housing. On one of these two devices, the button and the roller are located at the two ends of the front face of the case, while on the other device, these two members are located respectively one on and the other under the case.
Sur un quatrième appareil connu, le rôle du poussoir est assuré par un manche pivotant sur un côté du boîtier et l'élément applicateur d'adhésif est constitué par la bobine débitrice elle-même dont la périphérie émerge du dessous du boîtier.On a fourth known device, the role of the pusher is provided by a pivoting handle on one side of the housing and the adhesive applicator element is constituted by the supplying coil itself, the periphery of which emerges from below the housing.
Ces quatre appareils connus répondent par leurs différences à des usages différents, industriels ou domestiques, ainsi qu'à des critères d'ergonomie différents destinés à rendre leur manipulation aussi aisée que possible. Ils ont cependant ceci de commun qu'une certaine attention doit être portée à la synchronisation des actions manuelles de poussée et de relâchement du poussoir à rappel élastique de commande d'actionnement du frein avec le début et la fin du parcours d'encollage de l'objet à encoller.These four known devices respond by their differences to different uses, industrial or domestic, as well as to different ergonomic criteria intended to make their handling as easy as possible. They have however in common that a certain attention must be brought to the synchronization of the manual actions of pushing and of release of the push-button with elastic return of brake actuation control with the beginning and the end of the course of gluing of the object to be glued.
En effet, avec ces appareils applicateurs d'adhésif-transfert, le freinage de la bobine débitrice doit être supprimé par pression manuelle sur le poussoir au moins dès le début de la course d'encollage sous peine, en cas de retard, de casser le film d'adhésif par arrachement, le ruban étant bloqué et ne pouvant avancer. A la fin de la course d'encollage, l'arrêt de l'encollage nécessite la rupture franche du film d'adhésif porté par le ruban et, pour que cela soit fait proprement et avec précision, il faut que la bobine débitrice soit bloquée par relâchement manuel du poussoir au moment précis de l'arrivée de la zone d'appui de l'élément applicateur d'adhésif sur la limite prévue de l'encollage, et avant l'arrêt de la course de déplacement de l'appareil.In fact, with these adhesive transfer applicator devices, the braking of the supply reel must be removed by manual pressure on the pusher at least from the start of the gluing stroke, otherwise, in the event of delay, breaking the adhesive film torn off, the tape being blocked and unable to advance. At the end of the gluing stroke, stopping the gluing requires a frank break of the adhesive film carried by the tape and, for this to be done properly and with precision, the supplying reel must be blocked by manual release of the pusher at the precise moment of the arrival of the support zone of the adhesive applicator element on the planned limit of gluing, and before stopping the movement of the device.
L'utilisateur doit donc à la fois surveiller attentivement la position de la zone d'appui de l'élément applicateur d'adhésif sur l'objet à encoller et synchroniser ses actions manuelles de poussée et de relâchement du poussoir avec le passage de cette zone sur les limites critiques de début et de fin d'encollage, et ceci d'une seule main qui est chargée en même temps du guidage et de l'orientation du boîtier de l'appareil par rapport à la surface de l'objet à encoller.The user must therefore both carefully monitor the position of the support area of the adhesive applicator element on the object to be bonded and synchronize his manual actions of pushing and releasing the pusher with the passage of this area. on the critical limits of start and end of gluing, and this with one hand which is responsible at the same time for guiding and orienting the housing of the device relative to the surface of the object to be glued .
Sur un cinquième appareil connu, la synchronisation des actions de poussée et de relâchement du poussoir avec le début et la fin de la course d'encollage est rendue semi-automatique. Pour obtenir cet effet, le poussoir de cet appareil est situé sur la même face du boîtier que l'élément applicateur d'adhésif et proche en avant de ce dernier dans le sens prévu du déplacement de l'appareil le long de la course d'encollage. Le poussoir est ici un patin de glissement et l'élément applicateur d'adhésif un rouleau. De la sorte, au début de la course d'encollage, le patin-poussoir est automatiquement sollicité à la pression de l'appareil sur l'objet à encoller, la seule précaution à prendre étant de tenir la face du boîtier présentant ces deux organes parrallèle à la surface de l'objet à encoller. A la fin de la course d'encollage, et alors que le rouleau applicateur d'adhésif est toujours maintenu pressé sur l'objet encollé, l'utilisateur doit basculer le boîtier en arrière par rapport au sens d'avance, par rotation autour de la zone d'appui du rouleau sur l'objet, afin de permettre le relâchement du patin-poussoir par action de son rappel élastique, puis tirer l'appareil pour rompre le film d'adhésif.On a fifth known device, the synchronization of the pushing and releasing actions of the pusher with the start and the end of the gluing stroke is made semi-automatic. To obtain this effect, the pusher of this device is located on the same face of the housing as the adhesive applicator element and close in front of the latter in the expected direction of movement of the device along the travel of gluing. The pusher is here a sliding pad and the adhesive applicator element a roller. In this way, at the start of the gluing stroke, the push-on pad is automatically pressed upon the pressure of the device on the object to be glued, the only precaution to be taken being to hold the face of the box having these two members parallel to the surface of the object to be glued. At the end of the gluing stroke, and while the adhesive applicator roller is still kept pressed on the glued object, the user must tilt the box back with respect to the direction of advance, by rotation around the bearing area of the roller on the object, in order to allow the release of the pusher pad by action of its elastic return, then pull the device to break the film of adhesive.
Le semi-automatisme de cet appareil libère l'utilisateur du maniement direct du poussoir par un doigt de la main qui tient le boîtier, ce qui simplifie déjà le processus de manipulation pendant l'opération d'encollage. La synchronisation des actions du poussoir pose moins de problèmes du fait qu'elle est automatique en début de course d'encollage et qu'elle est obtenue par basculement du boîtier en fin de course d'encollage.The semi-automation of this device frees the user direct handling of the pusher by a finger of the hand holding the casing, which already simplifies the handling process during the gluing operation. The synchronization of the actions of the pusher poses fewer problems because it is automatic at the start of the gluing stroke and that it is obtained by tilting the housing at the end of the gluing stroke.
Cependant, lorsque cet appareil semi-automatique est utilisé pour encoller sur toute la longueur et jusqu'au bord d'un objet épais, tel que par exemple le couvercle d'une boîte, il ne permet pas sans autres manipulations supplémentaires délicates, d'appliquer l'adhésif jusqu'au bord de cet objet. En effet, avant la fin de la course d'encollage prévu, le patin-poussoir sort de la surface de l'objet et, par effet de son rappel élastique, actionne le frein et bloque la bobine débitrice avant que le rouleau applicateur ait fini sa course d'encollage jusqu'au bord de l'objet. Pour pouvoir finir l'encollage il faut soit le reprendre dans l'autre sens, après avoir retourné l'appareil, auquel cas un problème délicat de raccordement de film d'adhésif se pose, soit glisser un doigt de l'autre main sous l'appareil pour maintenir le patin-poussoir relevé à l'encontre de son rappel élastique jusqu'à la fin de la course prévue d'encollage, ce qui peut ne pas être toujours possible selon l'épaisseur de l'objet et l'espace environnant.However, when this semi-automatic device is used to glue over the entire length and to the edge of a thick object, such as for example the lid of a box, it does not allow, without other delicate additional manipulations, apply the adhesive to the edge of this object. In fact, before the end of the planned gluing stroke, the push-shoe leaves the surface of the object and, by the effect of its elastic return, activates the brake and blocks the supplying coil before the applicator roller has finished its glue stroke to the edge of the object. To be able to finish gluing, you must either take it back in the other direction, after having turned the device over, in which case a delicate problem of adhesive film connection arises, or slide a finger of the other hand under the device to keep the push-up shoe raised against its elastic return until the end of the planned gluing stroke, which may not always be possible depending on the thickness of the object and the space surrounding.
Enfin, le document EP-A2-0 263 926, compris dans l'état de la technique au sens de l'article 54 (3) de la CBE, décrit un appareil du genre spécifié en début d'exposé; dans cet appareil le poussoir est constitué par l'élément applicateur d'adhésif, lui-même constitué par un rouleau monté rotatif en bout d'un levier pivotant dont l'autre extrémité est appelée à bloquer, respectivement libérer, la rotation de la bobine débitrice.Finally, document EP-A2-0 263 926, included in the state of the art within the meaning of Article 54 (3) of the EPC, describes an apparatus of the kind specified at the start of the presentation; in this device, the pusher consists of the adhesive applicator element, itself constituted by a roller mounted to rotate at the end of a pivoting lever, the other end of which is called upon to block, respectively release, the rotation of the spool debtor.
Cette solution simplifie encore plus les manipulations de l'appareil en ce sens que la pression et le relâchement du poussoir se font naturellement et respectivement à l'application et au retrait de la pression de l'appareil sur l'objet à encoller, et ceci sans nécessiter de mouvements supplémentaires de basculement du boîtier ou de retenue du poussoir en fin de parcours d'encollage. En outre, le poussoir étant constitué par l'élément applicateur d'adhésif lui-même, le semi-automatisme appliqué se trouve simplifié par la suppression d'un organe, et le problème soulevé par l'espacement entre poussoir et élément applicateur est supprimé; l'utilisateur peut même omettre, dans ce dernier cas, de soulever l'appareil en fin de parcours puisque le freinage se fait automatiquement par arrivée dans le vide de l'élément applicateur dès le dépassement du bord de l'objet.This solution further simplifies the handling of the device in the sense that the pressure and the release of the pusher are done naturally and respectively upon application and removal of the pressure from the device on the object to be glued, and this without requiring additional movements of tilting the housing or retaining the pusher at the end of the gluing course. In addition, the pusher being constituted by the adhesive applicator element itself, the semi-automation applied is simplified by the elimination of an organ, and the problem raised by the spacing between pusher and applicator element is eliminated. ; the user can even omit, in the latter case, to lift the device at the end of the journey since braking is done automatically by arriving in the vacuum of the applicator element as soon as the object edge is exceeded.
L'invention a pour but un appareil présentant les avantages fonctionnels précités dans un environnement encore plus favorable.The object of the invention is to provide an apparatus having the above-mentioned functional advantages in an even more favorable environment.
A cet effet, l'appareil selon l'invention comprend un boîtier ouvrable dans lequel est montée mobile une platine, une bobine débitrice montée à rotation sur la platine et sur laquelle est enroulé un ruban porteur d'un film d'adhésif détachable, cette bobine étant disposée partiellement en saillie hors du boîtier pour servir d'élément applicateur d'adhésif, une bobine réceptrice également montée à rotation sur la platine au voisinage de la bobine débitrice, une transmission des mouvements rotatifs entre la bobine débitrice et la bobine réceptrice, montée sur la platine pour assurer le réenroulement synchrone du ruban autour de la bobine réceptrice, et un dispositif de freinage de la rotation de la bobine débitrice, à rappel élastique, et agissant à l'encontre du déplacement de la platine dans le boîtier.To this end, the apparatus according to the invention comprises an openable housing in which a plate is movably mounted, a supply reel rotatably mounted on the plate and on which is wound a tape carrying a film of detachable adhesive, this reel being partially projecting from the housing to serve as an adhesive applicator element, a take-up reel also mounted for rotation on the plate in the vicinity of the take-up reel, a transmission of the rotary movements between the take-up reel and the take-up reel, mounted on the plate to ensure the synchronous rewinding of the ribbon around the take-up reel, and a braking device for the rotation of the supply coil, with elastic return, and acting against the movement of the plate in the housing.
De la sorte, on dispose de tous les avantages fonctionnels d'un poussoir constitué par l'élément applicateur d'adhésif, avec cependant l'avantage structurel résultant de la suppression d'un élément applicateur et poussoir indépendant des bobines débitrice et réceptrice, cet élément applicateur et poussoir étant ici constitué par la bobine débitrice elle-même.In this way, we have all the functional advantages of a pusher constituted by the adhesive applicator element, with however the structural advantage resulting from the elimination of an applicator and pusher element independent of the supply and take-up coils, this applicator element and pusher being here constituted by the supply coil itself.
Le dessin annexé représente, à titre d'exemple, une forme d'exécution de l'objet de l'invention.The accompanying drawing shows, by way of example, an embodiment of the subject of the invention.

La figure 2 en est une vue de profil partielle et en coupe, en position de travail.Figure 2 is a partial profile view in section, in the working position.
L'appareil représenté comprend une bobine débitrice 3 autour de laquelle est enroulé un ruban 6 porteur d'adhésif détachable, une bobine réceptrice 7, et une transmission de mouvements rotatifs entre la bobine débitrice 3 et la bobine réceptrice 7, constituée par un train de trois roues dentées 9, 10 et 11, dont les deux extrêmes 9 et 11 sont respectivement concentriques et solidaires de la bobine débitrice 3 et de la bobine réceptrice 7, cependant que la troisième 10 est intermédiaire aux deux autres.The apparatus shown comprises a
Les deux bobines 3 et 7 ainsi que les roues 9, 10 et 11 de la transmission de mouvements sont respectivement montées sur trois pivots 30, 31 et 32 solidaires d'une platine 33 rectangulaire montée mobile par translation dans un boîtier 34 à extrémités arrondies et présentant deux parois latérales 35 parallèles à la platine 33. Une partie de la périphérie de la bobine débitrice 3 est disposée en saillie hors d'une extrémité du boîtier 34.The two
La platine 33 comporte deux paires de lames élastiques transversales 36, de mêmes dimensions, espacées sur sa longueur et de part et d'autre de sa largeur, venues de forme avec ladite platine. Les extrémités de ces quatre lames élastiques 36 sont engagées dans et maintenues par quatre glissières latérales 37 solidaires deux à deux des deux parois latérales 35 du boîtier 34.The
Du côté opposé à la bobine débitrice 3, la platine 33 présente un doigt d'extension 38 portant à son extémité un pivot 39 sur lequel est articulé un levier de frein 40.On the side opposite to the
De part et d'autre de son articulation sur le pivot 39, le levier de frein 40 présente d'un côté une dent 41 d'engagement de la denture de la roue dentée 11 du train d'engrenages, et de l'autre côté un pivot 42 engagé dans un trou tiré 43 d'une console 44 solidaire du boîtier 34.

En position de repos montrée figure 1, les quatre lames élastiques 36 de la platine 33 maintiennent celle-ci en équilibre dans le boîtier 34 en position abaissée d'engagement de la dent 41 du levier de frein 40 dans la denture de la roue dentée 11 du train d'engrenages. Ceci fait que dans cette position et en l'absence de pression sur la bobine débitrice 3, cette dernière est bloquée en rotation.In the rest position shown in Figure 1, the four
En position de travail montrée partiellement figure 2, la pression de la main de l'utilisateur sur le boîtier 34 a pour effet de faire remonter la platine 33 à l'encontre de la force élastique des quatre lames 36 qui fléchissent jusqu'à la rencontre du doigt d'extension 38 avec la butee 45. Cette remontée a pour effet de faire pivoter le levier de frein 40 et de dégager la dent 41 de ce dernier de la denture de la roue dentée 11, et de permettre ainsi la rotation de la bobine débitrice 3 qui peut effectuer une course d'encollage.In the working position shown partially in Figure 2, the pressure of the user's hand on the
Des variantes peuvent être apportées sans sortir du cadre de l'invention.Variants can be made without departing from the scope of the invention.
Ainsi, par exemple, la mobilité de la platine 33 peut être réalisée par un pivotement au lieu d'une translation. Dans ce cas cette platine est montée inclinée dans un boîtier plus volumineux permettant ce pivotement sur une certaine course à la fin de laquelle la denture d'une roue dentée du train d'engrenages vient engager une dent solidaire du boîtier par exemple.Thus, for example, the mobility of the
