Description

L'invention concerne un consommable pour dispositif d'impression, comportant deux rouleaux porteurs d'un ruban d'impression qui sont soutenus par un support.The invention relates to a consumable for a printing device, comprising two rollers carrying a printing ribbon which are supported by a support.

ARRIERE-PLAN DE L'INVENTIONBACKGROUND OF THE INVENTION

On connaît des consommables comportant deux rouleaux porteurs d'un ruban d'impression qui sont commercialisés dans un emballage plastique adapté à soutenir les extrémités des rouleaux de sorte que les rouleaux soient maintenus dans une position identique à une position de service.Consumables are known comprising two rollers carrying a printing ribbon which are marketed in a plastic packaging adapted to support the ends of the rollers so that the rollers are maintained in a position identical to a service position.

L'emballage comporte une feuille en matière plastique thermoformée pour constituer un support des extrémités des rouleaux et un film soudé pour fermer l'emballage.The package comprises a thermoformed plastic sheet to form a support for the ends of the rolls and a welded film to close the package.

Pour mettre en place les rouleaux dans le dispositif d'impression, on retire le film de fermeture de façon à libérer l'accès aux rouleaux, puis on présente sur le support thermoformé une cassette comportant deux parois latérales découpées pour présenter des chemins de guidage terminés par des paliers de réception des extrémités des rouleaux.To set up the rollers in the printing device, the closing film is removed so as to release access to the rollers, then a cassette is provided on the thermoformed support having two cut side walls to present completed guideways. by receiving bearings of the ends of the rollers.

La cassette est présentée en regard du support thermoformé de sorte que les chemins de guidage s'étendent alors à l'aplomb des extrémités des rouleaux. On enfonce alors la cassette dans le support thermoformé jusqu'à provoquer l'encliquetage des extrémités des rouleaux dans les paliers de réception de la cassette, puis on retire la cassette (dont les rouleaux sont désormais solidaires) du support thermoformé pour la mettre en place dans le dispositif d'impression.The cassette is presented facing the thermoformed support so that the guide tracks then extend vertically above the ends of the rollers. The cassette is then pressed into the thermoformed support until the ends of the rollers are snapped into the receiving bearings of the cassette, and then the cassette (whose rollers are now secured) is removed from the thermoformed support to put it into place. in the printing device.

L'utilisation d'un support thermoformé maintenant les rouleaux n'est pas entièrement satisfaisante. En effet, une fois le film de fermeture enlevé, il n'est pas possible de retourner le support sans risquer de faire tomber les rouleaux. Cette disposition oblige à présenter la cassette par dessus les rouleaux, ce qui ne constitue pas le mouvement le plus naturel pour l'utilisateur.The use of a thermoformed support holding the rolls is not entirely satisfactory. Indeed, once the closing film removed, it is not possible to return the support without risk of falling the rollers. This provision obliges to present the cassette over the rollers, which is not the most natural movement for the user.

En outre, avec un tel support, il s'avère difficile de concevoir un dispositif d'impression recevant directement les rouleaux en raison d'une part du risque de chute des rouleaux lors de la mise en place de ceux-ci, et en raison d'autre part de la nécessité de prévoir autour de la zone de réception des rouleaux un dégagement important pour la pénétration du support thermoformé dans le dispositif d'impression.In addition, with such a support, it proves difficult to design a printing device directly receiving the rollers because of a risk of falling of the rollers during the introduction of the rollers, and because on the other hand the need to provide around the receiving zone rollers significant clearance for the penetration of the thermoformed support in the printing device.

OBJET DE L'INVENTIONOBJECT OF THE INVENTION

L'invention a pour objet un consommable pour dispositif d'impression permettant une mise en place aisée des rouleaux indifféremment sur une cassette ou directement dans le dispositif d'impression. L'invention concerne également un réceptacle particulièrement adapté au dégagement du support lors de la mise en place des rouleaux dans le réceptacle.The invention relates to a consumable for printing device allowing easy placement of the rollers indifferently on a cassette or directly in the printing device. The invention also relates to a receptacle particularly adapted to the release of the support during the introduction of the rollers in the receptacle.

BREVE DESCRIPTION DE L'INVENTIONBRIEF DESCRIPTION OF THE INVENTION

En vue de la réalisation de ce but, on propose un consommable pour dispositif d'impression, comportant deux rouleaux portant un ruban d'impression et destinés à être mis en place directement dans un réceptacle du dispositif d'impression, les rouleaux ayant des extrémités qui sont tenues par un support amovible adapté à maintenir les rouleaux immobiles entre eux dans une position identique à une position de service pour faciliter la mise en place des rouleaux dans le réceptacle. Selon l'invention, le support comprend une portion de matière en feuille pliée en U pour présenter deux parois latérales en regard qui comportent des orifices dans lesquels les extrémités des rouleaux sont engagées.With a view to achieving this object, there is provided a consumable for a printing device, comprising two rollers carrying a printing ribbon and intended to be put in place directly in a receptacle of the printing device, the rollers having ends which are held by a removable support adapted to keep the rollers immobile between them in a position identical to a service position to facilitate the introduction of the rollers in the receptacle. According to the invention, the support comprises a portion of U-folded sheet material for presenting two opposite side walls which comprise orifices in which the ends of the rollers are engaged.

Ainsi, le support en carton maintient positivement les rouleaux et forme un organe de manipulation des rouleaux qui peut être retourné sans risque de chute des rouleaux.Thus, the cardboard support positively maintains the rollers and forms a roller handling member which can be turned without risk of falling. rolls.

Les rouleaux peuvent ainsi être mis en place facilement sur une cassette en approchant les rouleaux par dessus la cassette, ce qui s'avère plus naturel. Les rouleaux peuvent également être mis en place dans un dispositif d'impression, quelle que soit l'orientation de la zone de réception des rouleaux. La minceur des parois latérales du support en feuille permet l'introduction du support même dans le cas d'un dégagement faible autour de la zone de réception des rouleaux. Le consommable de l'invention permet donc d'envisager l'introduction des rouleaux directement dans le dispositif d'impression.The rollers can thus be easily placed on a cassette by approaching the rollers over the cassette, which is more natural. The rolls can also be put into place in a printing device, regardless of the orientation of the roll receiving area. The thinness of the side walls of the sheet support allows the introduction of the support even in the case of a small clearance around the receiving area of the rollers. The consumable of the invention therefore makes it possible to envisage the introduction of the rollers directly into the printing device.

DESCRIPTION DETAILLEE DE L'INVENTIONDETAILED DESCRIPTION OF THE INVENTION

En référence à la figure 1, le consommable 1 selon l'invention comporte un support 2 en carton destiné à porter des rouleaux 7 porteurs d'un ruban d'impression 8 ici figurés en transparence pour mieux faire apparaître le support 2.With reference to FIG. 1, the consumable 1 according to the invention comprises a cardboard support 2 intended to carry rollers 7 carrying a printing ribbon 8 shown here in transparency to better reveal the support 2.

Le support 2 comporte une base 3 et deux parois latérales 4 en regard, qui forment une structure en U de préférence obtenue par pliage d'un flan de carton découpé.The support 2 comprises a base 3 and two lateral walls 4 opposite, which form a U-shaped structure preferably obtained by folding a blank of cardboard cut.

L'une des parois latérales 4 comporte des orifices circulaires 5, tandis que l'autre paroi latérale 4 comporte des orifices ayant des contours non circulaires 6, se présentant ici sous forme de deux découpes en demi-lune. Les orifices 5,6 sont destinés à recevoir les extrémités des rouleaux 7.One of the side walls 4 has circular orifices 5, while the other side wall 4 has orifices having non-circular contours 6, here in the form of two half-moon cutouts. The orifices 5, 6 are intended to receive the ends of the rollers 7.

En référence à la figure 2, chacun des rouleaux 7 comporte une première extrémité circulaire 9 insérée axialement dans un des orifices circulaires 5. Chacun des rouleaux 7 comporte une seconde extrémité fendue 10 terminée par deux branches insérées axialement dans les découpes en demi-lune d'un des orifices non-circulaires 5.Referring to Figure 2, each of the rollers 7 has a first circular end 9 inserted axially into one of the circular orifices 5. Each of the rollers 7 has a second split end 10 terminated by two branches inserted axially into the half-moon blanks d. one of the non-circular orifices 5.

La coopération des extrémités fendues 10 avec les orifices non-circulaires 5 permet l'immobilisation en rotation les rouleaux 7 sur le support 2. Les rouleaux 7 sont de préférence disposés sur le support 2 de façon qu'une portion libre de ruban d'impression 8 s'étendant entre les rouleaux 7 soit tendue.The cooperation of the slotted ends 10 with the non-circular orifices 5 makes it possible to immobilize the rollers 7 on the support 2 in rotation. The rollers 7 are preferably arranged on the support 2 so that a free portion of printing ribbon 8 extending between the rollers 7 is stretched.

Le support 2 forme un organe de manipulation des rouleaux 7 qui maintient les rouleaux 7 immobiles l'un par rapport à l'autre et qui permet leur mise en place aisée dans un réceptacle de dispositif d'impression, ici une cassette amovible 20.The support 2 forms a member for handling the rollers 7 which holds the rollers 7 immobile with respect to each other and which allows them to be put into place easily in a printing device receptacle, here a removable cassette 20.

La cassette 20 comporte une paroi de fond 24 à laquelle sont fixées des parois latérales 21 en regard découpées pour présenter des paliers 22 de réception des extrémités des rouleaux 7. Les paliers 22 s'étendent au bout de chemins de guidage 25 parallèles ayant des entrées évasées.The cassette 20 has a bottom wall 24 to which are attached side walls 21 cut away to have bearings 22 for receiving the ends of the rollers 7. The bearings 22 extend at the end of parallel guideways 25 having inputs flared.

Comme illustré, le support 2 est présenté par dessus la cassette 20 de sorte que les extrémités des rouleaux 7 soient en regard des entrées des chemins de guidage 25. A cet égard, on notera que le support 2 est adapté à maintenir les rouleaux 7 dans une position identique à une position de service de sorte que les rouleaux 7 se présentent naturellement en regard des entrées des chemins de guidage 25.As illustrated, the support 2 is presented over the cassette 20 so that the ends of the rollers 7 are opposite the inputs of the guide tracks 25. In this respect, it will be noted that the support 2 is adapted to hold the rollers 7 in a position identical to a service position so that the rollers 7 are naturally opposite the inputs of the guideways 25.

On notera également que le support 2 est ici retourné par rapport à la position illustrée à la figure 1. L'engagement des extrémités 9,10 des rouleaux dans les orifices 5,6 du support 2 réalise en effet un maintien positif des rouleaux 7 supprimant le risque de chute des rouleaux 7.It will also be noted that the support 2 is here turned over with respect to the position illustrated in FIG. 1. The engagement of the ends 9, 10 of the rollers in the orifices 5, 6 of the support 2 in effect provides a positive retention of the rollers 7 eliminating the risk of falling rollers 7.

Puis on fait pénétrer les extrémités des rouleaux 7 dans les chemins de guidage 25, jusqu'à placer les extrémités des rouleaux 7 dans les paliers 22. De façon connue en soi, les paliers 22 sont précédés d'une légère restriction, de façon à permettre un encliquetage des extrémités des rouleaux 7 lors de leur introduction dans les paliers 22.The ends of the rollers 7 are then penetrated into the guideways 25, until the ends of the rollers 7 are placed in the bearings 22. In a manner known per se, the bearings 22 are preceded by a slight restriction, so as to allow the ends of the rollers 7 to be latched when they are inserted into the bearings 22.

Comme cela est visible à la figure 3, la base 3 du support 2 a une longueur adaptée pour réaliser entre les parois latérales 4 du support 2 et la face d'extrémité des rouleaux 7 un espace suffisant pour le passage des parois latérales 21 de la cassette 20.As can be seen in FIG. 3, the base 3 of the support 2 has a length adapted to produce between the lateral walls 4 of the support 2 and the end face of the rollers 7 sufficient space for the passage of the lateral walls 21 of the cassette 20.

Une fois les extrémités des rouleaux 7 encliquetées dans les paliers 22 de la cassette 20, le support 2 est désolidarisé des rouleaux 7. A cet effet, et comme cela est visible aux figures 1 et 2, le support 2 comporte une languette 12 qui s'étend en saillie d'un bord terminal 13 d'une des parois latérales 4. Il suffit alors d'exercer une traction sur la languette 12 de façon à redresser la paroi latérale 4 et ainsi l'écarter des extrémités des rouleaux 7. Puis, une fois cette paroi latérale retirée, il est facile de retirer l'autre paroi latérale.Once the ends of the rollers 7 snap into the bearings 22 of the cassette 20, the support 2 is separated from the rollers 7. For this purpose, and as can be seen in FIGS. 1 and 2, the support 2 comprises a tongue 12 which is protrudes from an end edge 13 of one of the side walls 4. It is then sufficient to exert traction on the tongue 12 so as to straighten the side wall 4 and thus remove it from the ends 7. After this side wall is removed, it is easy to remove the other side wall.

En figure 4, on distingue la cassette 20 équipée des rouleaux 7 débarrassés de leur support 2, prête à être insérée dans un dispositif d'impression 30.In FIG. 4, there is a cassette 20 equipped with rollers 7 freed of their support 2, ready to be inserted into a printing device 30.

En variante illustrée à la figure 5, le support 2 comporte une languette 14 qui s'étend cette fois à partir d'un bord latéral 15 d'une des parois latérales 4. Des prédécoupes 16 s'étendent sur cette paroi pour permettre de détacher la partie extrême 17 de la paroi latérale 4 qui porte les orifices 6, sous l'effet d'une traction sur la languette 13.As a variant illustrated in FIG. 5, the support 2 comprises a tongue 14 which this time extends from a lateral edge 15 of one of the lateral walls 4. Pre-cuts 16 extend on this wall in order to detach the end portion 17 of the side wall 4 which carries the orifices 6, under the effect of a pull on the tongue 13.

La figure 6 illustre un réceptacle particulièrement adapté à un dégagement automatique du support lors de la mise en place des rouleaux dans le réceptacle du dispositif d'impression. Dans le mode de réalisation illustré, le réceptacle est comme précédemment une cassette amovible 20. Dans ce mode de réalisation les parois latérales 21 de la cassette comportent sur leur face externe une rampe 23 qui diverge vers l'extérieur à partir du bord d'introduction 26 du consommable. Lors de la mise en place des rouleaux les bords internes des parois latérales 4 du support 2 prennent chacun appui sur une rampe 23 de sorte que les parois latérales 4 fléchissent vers l'extérieur. Les dimensions des rampes 23 sont déterminées pour que les parois latérales 4 du support 2 soient dégagées des extrémités des rouleaux lorsque ces extrémités atteignent les paliers 22 du réceptacle. Ceci permet de simplifier la structure du support 2 en supprimant les languettes 12 ou 14.Figure 6 illustrates a receptacle particularly adapted to an automatic release of the support during the introduction of the rollers in the receptacle of the printing device. In the illustrated embodiment, the receptacle is as before a removable cassette 20. In this embodiment, the side walls 21 of the cassette have on their outer face a ramp 23 which diverges outwardly from the introduction edge. 26 of the consumable. When placing the rollers the inner edges of the side walls 4 of the support 2 each bear on a ramp 23 so that the side walls 4 bend outwards. The dimensions of the ramps 23 are determined so that the side walls 4 of the support 2 are released from the ends of the rollers when these ends reach the bearings 22 of the receptacle. This simplifies the structure of the support 2 by removing the tabs 12 or 14.

L'invention n'est pas limitée à ce qui vient d'être décrit, mais bien au contraire englobe toute variante entrant dans le cadre défini par les revendications.The invention is not limited to what has just been described, but on the contrary encompasses any variant within the scope defined by the claims.

En particulier, bien que l'on ait illustré le consommable comme permettant la mise en place des rouleaux sur un réceptacle se présentant ici sous la forme d'une cassette amovible, on pourra utiliser le consommable de l'invention pour la mise en place des rouleaux dans un réceptacle intégré au dispositif d'impression.In particular, although we have illustrated the Consumable as allowing the introduction of the rollers on a receptacle here in the form of a removable cassette, we can use the consumable of the invention for the introduction of the rollers in a receptacle integrated in the printing device.

Bien que le support comporte ici des orifices non circulaires comportant deux demi-lunes aptes à recevoir les extrémités fendues des rouleaux, le support pourra comporter d'autres types d'orifices non circulaires de contours homologues aux contours des extrémités non circulaires des rouleaux (par exemple une extrémité comportant un méplat). En variante, tous les orifices du support pourront être circulaires. On peut dans ce cas prévoir des orifices circulaires de diamètre légèrement inférieur au diamètre des extrémités des rouleaux de façon à arrêter les rouleaux en rotation par frottement sur le support.Although the support here comprises non-circular orifices having two half-moons adapted to receive the slit ends of the rollers, the support may comprise other types of non-circular orifices of contours homologous to the contours of the non-circular ends of the rollers (for example an end having a flat). Alternatively, all the holes of the support may be circular. In this case it is possible to provide circular orifices with a diameter slightly smaller than the diameter of the ends of the rollers so as to stop the rollers in rotation by friction on the support.

Bien que le support comporte ici une languette sur l'une des parois, le support pourra comporter une languette sur chacune des parois.Although the support here comprises a tongue on one of the walls, the support may include a tongue on each of the walls.

Bien que les rouleaux aient été illustrés avec des extrémités de même diamètre, on pourra prévoir de doter l'un des rouleaux d'extrémités ayant un diamètre supérieur au diamètre des extrémités de l'autre rouleau, ce qui permet, en donnant aux paliers et aux chemins de guidage des dimensions ajustées aux extrémités correspondantes, d'organiser un détrompage évitant une mise en place erronée du rouleau récepteur dans les paliers du rouleau dévidoir, et vice-versa.Although the rollers have been illustrated with ends of the same diameter, it may be provided to provide one of the end rollers having a diameter greater than the diameter of the ends of the other roll, which allows, by giving the bearings and to guide the dimensions of dimensions adjusted to the corresponding ends, to organize a keying avoiding misplacement of the receiving roller in the bearings of the reel roller, and vice versa.
