Abstract

Device for displaying posters and signs and method of preparing and changing same. The device is composed of several triangular prisms rotating simultaneously at regular intervals and cyclically changing their rotational direction by ± 120°, ± 240° or ± 360°. The posters are prepared by manual or automatic means in a workshop, and are restored and then cut into display strips. They can be changed by manual or automatic means. The frame profile cover (14) is removed, releasing the strips (16), together with the poster strips (10), from the springs (20), and then from the triangular prisms (13), enabling the poster strips (10) to be changed and repositioned. Linear shifting of the bar (21) rotates the triangular prisms (13). The flexible strips (22) provided on the bar (22) transform the linear movement thereof into a rotational movement of the cylinders (23). Another embodiment provides a rack (42) driving several toothed wheels (43). The device is suitable for displaying various posters and signs, and in particular advertizing posters which often need to be changed.

DISPOSITIF POUR LA PRESENTATION D'AFFICHE ET DE SIGNALISATION AINSI QUE LE PROCEDE DE PREPARATION ET DE CHANGEMENT D'AFFICHE DE CELUI-CI DEVICE FOR THE PRESENTATION OF A POSTER AND SIGNALING AS WELL AS THE METHOD OF PREPARING AND CHANGING THE POSTER THEREOF
La présente invention concerne un dispositif pour la présentation d'affiche et de signalisation ainsi que le procédé de préparation et de changement d'affiche de celui-ciThe present invention relates to a device for the presentation of posters and signage as well as the process for preparing and changing the poster thereof.
Actuellement, les affiches sont présentées par diverses méthodes qui nécessitent des dépenses importantes en temps et en mo> en La présentation d'affiche par des prismes triangulaires, disposées les unes à côté des autres tournant périodiquement et pre.sentant trois affiches, fait partie des panneaux qui nécessitent les pl us grands investissements en temps et en moyen pour la préparation d'affiche à exposer, ainsi que la réalisation des panneaux Le système habituel de changement d*affιche est composé de plusieurs étapes On se rend, d'abord, en camion sur le site d'exposition où, manuellement, on enlève les lamelles en aluminium qui forment des prismes triangulaires sur lesquels sont collées des bandes d'affiche. Les lamelles sont rangées dans le camion puis emmenées à l'atelier, où elles sont déchargées, puis trempées dans des bacs remplis d'eau chaude et ébouillantées afin de faciliter le retrait des anciennes bandes d'affiche à l'aide d'un grattoir. Les lamelles, nettoyées, sont disposées sur un gabarit et forment une surface permettant de coller l'affiche. Le collage se fait de manière traditionnelle avec un balai. Ensuite, il est nécessaire d'attendre que les affiches soient sèches pour permettre le découpage et la séparation des lamelles. Entre les lamelles, il y a un espace d'environ 5 mm, la partie de l'affiche se trouvant dans cet espace doit être enlevé par deux découpes entre les lamelles, par bandes, ce qui produit des déchets La découpe se fait manuellement, avec un cutter. Les lamelles sont rangées dans un camion et ramenées sur le site où elles sont disposées à leur position initiale Ce procédé implique une perte de temps et les risques de blessures sont importants puisque le travail s'effectue en hauteur, manuellement, avec des pièces et des outils tranchants De plus, le poids des lamelles composant les trois affiches d'un panneau est d'environ 140 kg. Malgré cela, cette méthode est la plus utilisée puisque c'est la plus efficace jusqu'à maintenant Mis à part tous ces problèmes techniques, il existe des problèmes esthétiques, à cause de la préparation manuelle complexe, le résultat étant très dépendant de la qualité de trav ail de l'ouvrier A cause de la pluie, il est courant que les bandes se décollent car elles ont été mal collées sur certaines lamelles Une autre méthode existante, q ui sur certai ns poi nts paraît posi ti ve, consi ste à découper une affi che en bande sans q u'el l e ait été reconstituée. A l a suite de cela, on se rend sur le site, on enl ève l es pri smes tri angul ai res une par une et on l es instal l e horizontal ement sur des tréteaux. Les prismes sontCurrently, the posters are presented by various methods which require significant expenditure of time and time. The presentation of poster by triangular prisms, arranged one next to the other rotating periodically and presenting three posters, is one of the panels that require large investments pl us time and means for the preparation of displays to exhibit, as well as carrying signs the usual system change * affιche consists of several steps we went, first, truck to the exhibition site where, manually, the aluminum strips are removed which form triangular prisms on which are stuck poster strips. The slats are stored in the truck and then taken to the workshop, where they are unloaded, then soaked in trays filled with hot water and scalded to facilitate the removal of the old poster strips using a scraper. . The strips, cleaned, are placed on a template and form a surface allowing to stick the poster. Bonding is done in the traditional way with a broom. Then, it is necessary to wait until the posters are dry to allow the cutting and separation of the slats. Between the slats, there is a space of about 5 mm, the part of the poster being in this space must be removed by two cuts between the slats, in strips, which produces waste The cutting is done manually, with a cutter. The slats are stored in a truck and brought back to the site where they are arranged in their initial position. This process involves a waste of time and the risk of injury is significant since the work is carried out at height, manually, with parts and cutting tools In addition, the weight of the slats making up the three posters of a panel is approximately 140 kg. Despite this, this method is the most used since it is the most effective so far Apart from all these technical problems, there are aesthetic problems, because of the complex manual preparation, the result being very dependent on the quality of work of the worker Because of the rain, it is common that the strips come off because they were badly glued on certain slats Another existing method, which on some points seems positive, consi ste to cut a poster into a strip without having been reconstructed. After that, we go to the site, we remove the triangular prisms one by one and we install it horizontally on trestles. The prisms are
SUBSTITI ITE SHEET (RULE 26) en aluminium et chaque face est couverte d'une latte transparente en plastique, en dessous se trouvent les bandes d'affiche. Les lattes s'enlèvent en position horizontale afin d'ôter les anciennes bandes d'affiche et de mettre les nouvelles bandes composées de deux parties par face. On remet ensuite les lattes, dès que les trois faces du prisme ont été changées, on remet les prismes uns par uns sur le panneau. Le système est plus rentable si on doit changer les trois affiches car il est nécessaire d'enlever les prismes pour le changement des trois, de deux, ou d'une seule affiche. La mise en place des lattes prend du temps puisque cela s'effectue horizontalement, ce qui représente un risque de brisure ou de déformation des lattes à cause de la longueur, et surtout si un seul ouvrier effectue la manoeuvre. De plus, leur manipulation atténue leur transparence. Le moyen par lequel les lattes sont liées aux profils en aluminium est assuré sut toute la longueur des arêtes ce qui diminue la surface de l'affiche entre les prismes, ainsi l'affiche perd son côté esthétique à cause des importantes lignes noires entre les prismes triangulaires. Ce procédé de changement d'affiche nécessite une certaine habilité de la part de l'ouvrier pour la découpe des bandes ce qui entraîne aussi des déchets.SUBSTITI ITE SHEET (RULE 26) aluminum and each side is covered with a transparent plastic slat, below are the poster strips. The slats can be removed in a horizontal position in order to remove the old poster strips and put the new strips made up of two parts per side. Then put the slats, as soon as the three faces of the prism have been changed, we put the prisms one by one on the panel. The system is more profitable if you have to change the three posters because it is necessary to remove the prisms for the change of the three, two, or a single poster. The installation of the slats takes time since this is done horizontally, which represents a risk of breakage or deformation of the slats because of the length, and especially if a single worker performs the maneuver. In addition, their manipulation reduces their transparency. The means by which the slats are linked to the aluminum profiles is ensured over the entire length of the edges, which decreases the surface of the poster between the prisms, thus the poster loses its aesthetic side because of the large black lines between the prisms. triangular. This poster change process requires a certain skill on the part of the worker for cutting the strips, which also results in waste.
En ce qui concerne le système de transmission de ce genre de panneaux, il existe plusieurs solutions: les courroies crantées qui lient deux à deux le prismes triangulaires, ce qui nécessite une grande quantité de pièces mécaniques coûteuses et compliquées. De plus, pour éviter l'inclinaison de la première prisme par rapport à la dernière, il est nécessaire que les courroies crantées soient très tendues ce qui entraîne une pression sur les roulements sur lesquels se trouvent les axes, donc d'importants frottements. Ce système est coûteux et s'il y a des réparations, l'approche est difficile, il est souvent nécessaire de démonter tout le panneau pour de petites pannes. Un autre système fonctionne grâce à des cames qui entraînent d'importants frottements car la transmission est assurée par la pression et le frottement des pièces. La fabrication est coûteuse et les réparations entraînent le démontage entier du panneau pour de petites pannes.Regarding the transmission system of this kind of panels, there are several solutions: the toothed belts which link the triangular prisms two by two, which requires a large amount of expensive and complicated mechanical parts. In addition, to avoid the inclination of the first prism relative to the last, it is necessary that the toothed belts are very tight which causes pressure on the bearings on which the axes are located, therefore significant friction. This system is expensive and if there are repairs, the approach is difficult, it is often necessary to dismantle the entire panel for small breakdowns. Another system works with cams which cause significant friction because the transmission is ensured by the pressure and friction of the parts. The manufacturing is expensive and the repairs involve the entire dismantling of the panel for small breakdowns.
Le dispositif, présenté dans la demande de brevet N° 94 09971 permet de remédier à ces inconvénients.The device presented in patent application No. 94 09971 overcomes these drawbacks.
L'invention implique la préparation d'affiche en atelier de manière manuelle ou automatique à l'aide d'un manipulateur. L'affiche peut être composée d'un ou plusieurs morceaux, cela dépend de sa grandeur, par exemple pour les panneaux publicitaires de 12 m2, l'affiche est composée de 4, 6 ou 8 morceaux. Le manipulateur prend les morceaux d'affiche à l'aide des ventouses du manipulateur, dans un ordre déterminé et les place les uns à coté des autres sur la table de travail selon un procédé déterminé. Les ventouses de la table de travail fixent les morceaux d'affiche. Ensuite, s 'effectue l'assemblage des morceaux d'affiche à l'aide de bandes adhésives pour obtenir une affiche complète. Une fois assemblée, l'affiche est déplacée à l'aide du manipulateur, vers le bord de la table de travail, équipée d'un cutter afin de découper l'affiche en bande. Le déplacement se fait à distance égale et déterminée, la coupe se fait en une fois par bande, sans déchets. Le cutter se déplace sur la longueur du bord de la table, sur le guidage du cutter correspondant. En dessous du bord de la table se trouve une boîte où tombent les bandes d'affiche. Les bandes d'affiche sont marquées et emballées dans des boîtes pour le transport.The invention involves the preparation of posters in the workshop manually or automatically using a manipulator. The poster can be made up of one or more pieces, it depends on its size, for example for 12 m 2 billboards, the poster is made up of 4, 6 or 8 pieces. The manipulator takes the pieces of poster using the suction cups of the manipulator, in a determined order and places them next to each other others on the work table according to a determined process. The suction cups of the work table fix the pieces of poster. Next, the poster pieces are assembled using adhesive strips to obtain a complete poster. Once assembled, the poster is moved using the manipulator, to the edge of the work table, equipped with a cutter to cut the poster into strips. The movement is made at equal and determined distance, the cutting is done at once by strip, without waste. The cutter moves along the edge of the table, on the guide of the corresponding cutter. Below the edge of the table is a box where the poster strips fall. The poster strips are marked and packed in boxes for transport.
Les bandes d'affiche se transportent jusqu'au site où se trouve le dispositif, composé d'un cadre avec les prismes triangulaires positionnés les uns à côté des autres, et ceux-ci sont composés de plusieurs éléments. Le prisme triangulaire possède sur son extrémité, un élément pointu qui lie le profil triangulaire principal à l'enveloppe triangulaire transparente et avec sa pointe positionne une de ses extrémités du prisme triangulaire dans un guidage de rotation, avec articulation sphérique, et sur l'autre extrémité un élément creux avec lequel il lie et positionne la deuxième extrémité du prisme triangulaire sur un des axes de rotation. Le positionnement par cette méthode permet l'enlèvement du prisme triangulaire : en le soulevant, on le libère de l'axe de rotation, en l'inclinant d'un certain angle grâce au guidage de rotation, avec articulation sphérique, on le retire du guidage. Ce retrait est pratique pour le nettoyage, le changement, la réparation et le démontage. Le prisme triangulaire contient le profil triangulaire principal qui a des canaux sur ces trois faces par lesquels sont enfilées trois lamelles, ainsi que trois arêtes permettant le positionnement de l'enveloppe triangulaire transparente avec un jeu déterminé, afin d'assurer le passage des bandes d'affiche. La lamelle comporte des profils en caoutchouc avec lesquels, à l'aide du frottement, ils lient les bandes d'affiche en la plaquant sur la surface intérieure de l'enveloppe triangulaire transparente, c'est-à-dire que le retrait de la lamelle, entraîne le retrait de la bande d'affiche, par contre son immobilité permet la fixation de la bande d'affiche. La lamelle possède des arêtes sur lesquelles roulent les galets pendant le retrait automatique. La lamelle possède aussi des rainures permettant la liaison des lamelles avec les canaux, placés sur les faces des prismes triangulaires principaux. Tous les éléments du prisme triangulaire se trouvent à l'intérieur de l'enveloppe triangulaire transparente, où, dans les angles intérieurs se touchent les bords des bandes d'affiche. Ce contact est possible grâce au jeu entre le bord du profil triangulaire principal et la face interne de l'enveloppe triangulaire transparente, c'est-à-dire que les bandes d'affiche recouvrent totalement les trois faces intérieures de l'enveloppe triangulaire transparente. Sur les trois faces d'une des extrémités du profil triangulaire principal est fixé un ressort qui peut avoir deux positions: la première, où la lamelle est bloquée avec la bande d'affiche, à l'intérieur pour l'exposition, et la deuxième où la lamelle est libérée pour le retrait ou l'insertion, avec la bande d'affiche. Pour le changement des bandes d'affiche, il faut ôter le couvercle du profil du cadre, ainsi on libère le passage des lamelles avec les bandes d'affiche pendant le retrait ou l'insertion dans les prismes triangulaires. Ensuite, on libère les lamelles avec les bandes d'affiche, bloquées par les ressorts. Le retrait et l'insertion des lamelles, avec les bandes d'affiche, se fait manuellement ou automatiquement avec un manipulateur fixé sur le cadre et équipé de deux galets par lamelle. L'entraînement des galets est assuré par un moto-réducteur, commandé par l'ouvrier. Une fois la lamelle libérée, elle tombe avec ses deux arêtes prises entre les deux galets. La rotation des galets permet le retrait des lamelles avec les bandes d'affiche. Ce retrait se fait partiellement, c'est-à-dire que le bout de la lamelle avec celui de la bande d'affiche reste dans le prisme triangulaire. Les vieilles bandes d'affiche s'enlèvent et sont remplacées par les nouvelles. Les anciennes bandes peuvent être détruites ou gardées pour une nouvelle exposition puisqu'elles sont intactes. Les lamelles avec les bandes d'affiche s'insèrent dans les prismes triangulaires par le procédé inverse, les ressorts prennent leur position initiale, automatiquement ce qui permet le blocage des lamelles avec les bandes d'affiche dans les prismes triangulaires pour l'exposition. Le procédé se répète pour chaque lamelle dans le cas du changement manuel, ou par groupe de lamelles dans le cas automatique avec le manipulateur.The poster strips are transported to the site where the device is located, composed of a frame with triangular prisms positioned next to each other, and these are composed of several elements. The triangular prism has at its end a pointed element which links the main triangular profile to the transparent triangular envelope and with its tip positions one of its ends of the triangular prism in a rotation guide, with spherical articulation, and on the other end a hollow element with which it links and positions the second end of the triangular prism on one of the axes of rotation. Positioning by this method allows the triangular prism to be removed: by lifting it, it is released from the axis of rotation, by tilting it at a certain angle thanks to the rotation guide, with spherical articulation, it is removed from the guidance. This removal is convenient for cleaning, changing, repairing and dismantling. The triangular prism contains the main triangular profile which has channels on these three faces through which three slats are threaded, as well as three edges allowing the positioning of the transparent triangular envelope with a determined clearance, in order to ensure the passage of the strips. poster. The lamella has rubber profiles with which, by means of friction, they bind the poster strips by pressing it on the inner surface of the transparent triangular envelope, that is to say that the removal of the lamella, causes the poster strip to be removed, however its immobility allows the poster strip to be fixed. The lamella has edges on which the rollers roll during automatic removal. The strip also has grooves allowing the connection of the strips with the channels, placed on the faces of the main triangular prisms. All the elements of the triangular prism are inside the transparent triangular envelope, where, in the interior angles touch the edges poster strips. This contact is possible thanks to the play between the edge of the main triangular profile and the internal face of the transparent triangular envelope, that is to say that the poster strips completely cover the three interior faces of the transparent triangular envelope. . On the three faces of one of the ends of the main triangular profile is fixed a spring which can have two positions: the first, where the strip is blocked with the poster strip, inside for the exhibition, and the second where the coverslip is released for removal or insertion, with the poster strip. To change the poster strips, remove the cover from the frame profile, thus freeing the passage of the slats with the poster strips during removal or insertion into the triangular prisms. Then, we release the slats with the poster strips, blocked by the springs. The removal and insertion of the strips, with the poster strips, is done manually or automatically with a manipulator fixed on the frame and equipped with two rollers per strip. The rollers are driven by a geared motor, controlled by the worker. Once the cover is released, it falls with its two edges caught between the two rollers. The rotation of the rollers allows the removal of the slats with the poster strips. This removal is done partially, that is to say that the end of the strip with that of the poster strip remains in the triangular prism. The old poster strips are removed and are replaced by the new ones. The old tapes can be destroyed or kept for a new exhibition since they are intact. The strips with the poster strips are inserted into the triangular prisms by the reverse process, the springs take their initial position, automatically which allows the blocking of the strips with the poster strips in the triangular prisms for the exhibition. The process is repeated for each slat in the case of manual change, or by group of slats in the automatic case with the manipulator.
Dans le cas d' une longue exposition de l'affiche qui peut provoquer l ' adhésion des bandes d'affiche à l'intérieur des enveloppes triangulaires transparentes à cause de l'humidité, l'invention, décrite dans la demande de brevet N° 94 13668 apporte une première variante. Celle-ci est basée sur le prisme décrit ci-dessus, chaque face comporte une bande d'affiche positionnée entre la lamelle et la bande transparente supplémentaire, ces trois éléments étant, enfilés entre la face du profil triangulaire principal et la face intérieure de l'enveloppe triangulaire transparente, et bloqués pour l'exposition par un ressort. L'insertion et le retrait des lamelles, avec les bandes d'affiche, sont facilités grâce au faible frottement. De plus, les faces intérieures de l'enveloppe triangulaire transparente sont protégées des couleurs de l'affiche qui peuvent s'imprimer lors de longues expositions, où de l'effet adhésif de la bande d'affiche, provoqué par l'humidité. Aussi, les bandes transparentes s'enlèvent facilement et peuvent être nettoyées ou remplacées par de nouvelles, si nécessaire.In the case of a long exposure of the poster which can cause the adhesion of the poster strips inside the transparent triangular envelopes due to humidity, the invention, described in patent application No. 94 13668 brings a first variant. This is based on the prism described above, each side has a poster strip positioned between the strip and the additional transparent strip, these three elements being, threaded between the side of the main triangular profile and the inner side of the 'transparent triangular envelope, and blocked for exposure by a spring. The insertion and removal of the slats, with the poster strips, are facilitated thanks to the low friction. In addition, the interior faces of the transparent triangular envelope are protected from the colors of the poster which can be printed during long exposures, or from the adhesive effect of the poster strip, caused by humidity. Also, the transparent strips are easily removed and can be cleaned or replaced with new ones, if necessary.
Dans le cas d'un changement d'affiche rendu impossible à cause d'obstacles pouvant obstruer le passage des lamelles, l' invention de la demande de brevet N° 94 13668 apporte une deuxième variante. Celle-ci conserve le même prisme, chaque face comporte une bande d'affiche positionnée entre une bande souple, remplaçant la lamelle, et une bande transparente. Ces trois bandes sont enfilées entre la face du profil triangulaire principal, où sont fixés des profils souples, et la face intérieures de l'enveloppe triangulaire transparente. Les profils souples permettent le plaquage des trois bandes sur la surface intérieure de l'enveloppe triangulaire transparente, et assurent le bon positionnement de l'enveloppe triangulaire transparente et la bonne présentation de la bande d'affiche. Les trois bandes peuvent être enfilées à l'aide de la courroie du prisme. Cette courroie est fixée par son extrémité, à l'extrémité de la bande souple, elle passe par un galet, fixé à l'extrémité du profil triangulaire principal, et s'étend vers la deuxième extrémité du profil triangulaire principal. La courroie contient sur sa deuxième extrémité un élément glissant qui se bloque sur le ressort et soutient les trois bandes en position d'exposition. Cette dernière variante, peut aussi être utilisée sans bandes transparentes. Elle convient aux panneaux placés sur des sites souvent obstrués par des obstacles, gênants le passage des lamelles. Le prisme triangulaire peut aussi être utilisé sans la courroie du prisme, le galet et l'élément glissant, car, les trois bandes étant légères, elles sont bien positionnées par la pression des profils souples, ce qui convient pour les panneaux qui nécessitent un changement d'affiche rare. Dans ce cas, l'insertion des bandes d'affiche est manuelle, elle se fait par un outil s'insérant dans le canal du prisme triangulaire principal et entraînant l'extrémité de la bande souple jusqu'au sommet du prisme triangulaire.In the case of a change of poster made impossible because of obstacles which could obstruct the passage of the slats, the invention of patent application No. 94 13668 provides a second variant. This retains the same prism, each side has a poster strip positioned between a flexible strip, replacing the strip, and a transparent strip. These three bands are threaded between the face of the main triangular profile, where flexible profiles are fixed, and the inside face of the transparent triangular envelope. The flexible profiles allow the plating of the three strips on the inner surface of the transparent triangular envelope, and ensure the correct positioning of the transparent triangular envelope and the good presentation of the poster strip. The three bands can be threaded using the prism strap. This belt is fixed by its end, at the end of the flexible strip, it passes through a roller, fixed at the end of the main triangular profile, and extends towards the second end of the main triangular profile. The strap contains a sliding element on its second end which locks onto the spring and supports the three strips in the exposure position. This last variant can also be used without transparent strips. It is suitable for panels placed on sites often obstructed by obstacles, interfering with the passage of the slats. The triangular prism can also be used without the prism belt, the roller and the sliding element, because, the three strips being light, they are well positioned by the pressure of the flexible profiles, which is suitable for panels that require a change rare poster. In this case, the insertion of the poster strips is manual, it is done by a tool inserted into the channel of the main triangular prism and driving the end of the flexible strip to the top of the triangular prism.
Le changement des bandes d'affiche se fait manuellement ou automatiquement à l'aide d'un manipulateur. Lors du changement avec le manipulateur, l'élément clé, fixé sur la courroie, enroulé sur la bobine de courroie, est imbriqué dans l'élément glissant afin de le libérer du ressort. L'élément glissant, libéré du ressort, permet le retrait de la bande d'affiche par l'enroulement de la bande souple et de la bande transparente respectivement, sur la bobine de bande souple motorisée et la bobine de bande transparente, également motorisée, qui se trouvent dans le manipulateur. L'enroulement des bandes c'est-à-dire le retrait de la bande d'affiche, provoque le déroulement de la bobine de courroie. Ainsi, l'insertion se fait par le procédé inverse d'enroulement de la bobine de courroie motorisée, ce qui entraîne le déroulement des bandes et l'entrée de la nouvelle bande d'affiche dans le prisme triangulaire. En fin de parcours, l'élément clé est éjecté automatiquement par le ressort, qui bloque l'élément glissant. Le manipulateur est doté de deux cartouches, l'une destinée au stockage des nouvelles bandes d'affiche qui seront insérées dans les prismes triangulaires, et l'autre vide, destinée au chargement des anciennes bandes d'affiche. Le manipulateur peut être utilisé lors d'intempéries, puisqu'il est couvert par une plaque transparente, qui protège les bandes d'affiche, et permet une visualisation des opérations. Dans le cas manuel, il suffit d'avoir une courroie avec un élément clé pour le changement d'affiche. Toutes ces solutions sont adaptées aussi bien, à des prismes ayant une coupe triangulaire, exposant trois faces, qu'à des prismes ayant une, deux, ou quatre faces d'exposition.The change of the poster strips is done manually or automatically using a manipulator. When changing with the manipulator, the key element, fixed on the belt, wound on the belt reel, is nested in the sliding element in order to release it from the spring. The sliding element, released from the spring, allows the removal of the poster strip by winding the flexible strip and the transparent strip respectively, on the motorized flexible strip reel and the transparent strip reel, also motorized, which are located in the manipulator. The winding of the strips, that is to say the removal of the poster strip, causes the unwinding of the belt reel. Thus, the insertion is done by the reverse process of winding the motorized belt reel, which leads to the unwinding of the strips and the entry of the new poster strip into the triangular prism. At the end of the journey, the key element is automatically ejected by the spring, which blocks the sliding element. The manipulator is equipped with two cartridges, one intended for the storage of the new poster strips which will be inserted in the triangular prisms, and the other empty, intended for the loading of the old poster strips. The manipulator can be used during inclement weather, since it is covered by a transparent plate, which protects the poster strips, and allows visualization of operations. In the manual case, it is enough to have a belt with a key element for the change of poster. All these solutions are suitable both for prisms having a triangular section, exposing three faces, and for prisms having one, two, or four exposure faces.
Les prismes triangulaires effectuent une rotation périodique synchronisée de 120°, avec un changement périodique du sens de rotation de +/- 120°, +/- 240°, ou +/- 360° pour l'exposition des faces selon la suite d'exposition et la période de temps souhaitées. Avec une telle rotation, il est possible d'exposer deux ou trois faces avec la suite et le temps d'exposition choisit. A cause de la rotation périodique, avec le changement du sens de rotation périodique, il est inutile d'utiliser un mécanisme de transmission qui permet la rotation toujours dans le même sens, c'est-à-dire que le mécanisme de transmission est simplifié. La transmission est réalisée avec les bandes flexibles, chacune est composée de deux bras disjoints, liés à la règle par ses extrémités et enroulés autour d'un cylindre ayant un axe de rotation sur lequel la partie médiane de la bande est fixée, ainsi qu'un bras médian qui une fois enroulé autour du cylindre passe au milieu des deux bras disjoints et avec lequel il est lié à la règle. De cette manière, les bandes flexibles sont fixées sur la règle qui s'étend presque sur toute la longueur du profil du cadre, et enroulées autour des cylindres avec les axes de rotation, sur lesquels elles sont aussi fixées, et permettent la transformation du mouvement linéaire de la règle par l'enroulement et le déroulement des bras, en un mouvement de rotation des cylindres avec les axes de rotation. Chaque axe de rotation est positionné sur deux guidages de rotation avec articulation sphérique, et sur chaque axe de rotation est positionné un prisme triangulaire. Ce procédé de transmission avec les bandes flexibles, convient au dispositif de grande dimension de part le prix des pièces et du montage. Pour les dispositifs de petite dimension, la variante la plus favorable est celle de la transmission où le mouvement linéaire est transformé en mouvement de rotation par une crémaillère qui entraîne plusieurs roues dentées sur les axes de rotation. Le choix de cette variante est lié au prix et au montage plus adapté au petit dispositif. Il est évident que le mouvement de la règle, provoque la rotation synchronisée de tous les prismes triangulaires car la règle entraîne toutes les bandes flexibles fixées sur elle. La règle est entraînée par un vérin électrique ou, pour les dispositifs de petite dimension, par un moto-réducteur.The triangular prisms perform a synchronized periodic rotation of 120 °, with a periodic change of the direction of rotation of +/- 120 °, +/- 240 °, or +/- 360 ° for the exposure of the faces according to the sequence of desired exposure and time period. With such a rotation, it is possible to expose two or three faces with the series and the exposure time chosen. Because of the periodic rotation, with the change of the direction of periodic rotation, it is useless to use a transmission mechanism which allows rotation always in the same direction, that is to say that the transmission mechanism is simplified . The transmission is carried out with the flexible bands, each consists of two disjoint arms, linked to the rule by its ends and wound around a cylinder having an axis of rotation on which the middle part of the band is fixed, as well as a middle arm which once wrapped around the cylinder passes in the middle of the two disjoint arms and with which it is linked to the rule. In this way, the flexible bands are fixed on the ruler which extends almost over the entire length of the profile of the frame, and wound around the cylinders with the axes of rotation, on which they are also fixed, and allow the transformation of the movement. linear rule by the winding and unwinding of the arms, in a rotational movement of the cylinders with the axes of rotation. Each axis of rotation is positioned on two rotation guides with spherical articulation, and on each axis of rotation is positioned a triangular prism. This process of transmission with flexible belts, suitable for large size devices due to the price of parts and assembly. For small devices, the most favorable variant is that of the transmission where the linear movement is transformed into a rotary movement by a rack which drives several toothed wheels on the axes of rotation. The choice of this variant is linked to the price and the mounting more suited to the small device. It is obvious that the movement of the ruler, causes the synchronized rotation of all the triangular prisms because the ruler drives all the flexible bands fixed on it. The rule is driven by an electric jack or, for small devices, by a gear motor.
L' invention apporte plusieurs avantages : le transport et la manipulation concernant le changement d'affiche, des lamelles en aluminium ou des prismes triangulaires ne sont plus nécessaires. Le transport grâce à un petit véhicule est nécessaire uniquement pour les affiches ce qui est beaucoup plus économique et rapide. Pendant le changement d'affiche, le véhicule n'encombre pas la circulation. La préparation d'affiche est minime, le collage avec les bandes adhésives est immédiat, de plus, il est inutile d'attendre le séchage pour la découpe. Aussi, il n'y a pas de déformation du papier due à l'humidité de la colle. Le nettoyage des lamelles, après chaque changement d'affiche n'existe plus. Ainsi, tous les risques de blessure, d'endommagement des pièces du dispositif, liés au changement d'affiche, sont inexistants. La durée de fonctionnement du dispositif est donc prolongée. Le changement d'affiche, demandant très peu de temps par rapport aux systèmes existants, est rentable même pour le changement d'une seule affiche par panneau. L'esthétique est améliorée puisque l'affiche se trouve sous du plastique transparent qui lui donne un éclat et la protège des intempéries. De plus, la distance entre les bandes d'affiche est très petite ce qui permet une exploitation maximale de la surface de l'affiche. L'affiche est découpée avec une seule coupe par bande d'affiche sans déchets. Le système de transmission produit un frottement minimal car la pression sur les guidages de rotation est minimale, c'est-à-dire qu'il demande un minimum d'énergie pour son fonctionnement. Les pannes sont réparables facilement car il est possible de changer des pièces sans pour autant démonter tout le panneau. Le système offre deux possibilités, pour la préparation et pour le changement d'affiche, manuelle ou automatique. Celui-ci permet le choix du nombre de face et du temps d'exposition. Il offre le choix des différentes dimensions du dispositif qui s'adapte aux diverses applications, par exemple les panneaux publicitaires de 3x4 m2 ou 3x8 m- et plus, les petits panneaux pour les autobus, trains, agences, magasins, ou dispositifs de signalisation pour les routes. Les dessins annexes illustrent l 'invention :The invention provides several advantages: transport and handling concerning the change of poster, aluminum strips or triangular prisms are no longer necessary. Transport using a small vehicle is only necessary for posters, which is much more economical and faster. During the change of poster, the vehicle does not obstruct traffic. Poster preparation is minimal, bonding with adhesive strips is immediate, moreover, there is no need to wait for drying for cutting. Also, there is no deformation of the paper due to the humidity of the glue. The cleaning of the slats, after each change of poster no longer exists. Thus, all the risks of injury, of damage to the parts of the device, linked to the change of poster, are nonexistent. The operating time of the device is therefore extended. The change of poster, requiring very little time compared to existing systems, is profitable even for the change of a single poster per panel. The aesthetics are improved since the poster is located under transparent plastic which gives it a shine and protects it from the weather. In addition, the distance between the poster strips is very small, which allows maximum use of the poster surface. The poster is cut with a single cut per poster strip without waste. The transmission system produces minimal friction because the pressure on the rotation guides is minimal, that is to say that it requires a minimum of energy for its operation. Breakdowns are easily repairable because it is possible to change parts without dismantling the entire panel. The system offers two possibilities, for preparation and for display change, manual or automatic. This allows the choice of the number of faces and the exposure time. It offers the choice of different dimensions of the device which adapts to various applications, for example advertising panels of 3x4 m 2 or 3x8 m- and more, small panels for buses, trains, agencies, stores, or signaling devices for roads.

- les figures 12, 13, et 14 représentent les phases d'imbrication de l'élément clé dans l'élément glissant. Sur la figure 1 est présenté la structure de préparation automatique d'affiche dans l'atelier. Le manipulateur ( 1 ) constitué de composants standardisés pour les manipulateurs, et la table de travail (2) où les dimensions et le déplacement du manipulateur ( 1 ) sont déterminés par rapport à la dimension maximale de l'affiche (3 ), pour laquelle elle est prévue. On peut apercevoir le guidage du manipulateur ( 1 ) grâce auquel est assuré le mouvement dans les trois axes de l'espace. Le manipulateur ( 1 ) prend les morceaux d'affiche (4), seulement si elle est composé de plusieurs morceaux, à l'aide de ses ventouses du manipulateur (5 ) et les posent sur la table de travail (2). La table de travail (2) est couverte de ventouses de la table de travail (6), avec lesquelles les morceaux d'affiche (4) sont fixés en bonne position. A l ' aide des bandes adhésives (7), on fait l'assemblage des morceaux d'affiche (4) en une seule affiche (3) complète. A l'aide du manipulateur ( 1 ), le déplacement successif de l'affiche (3 ) se fait vers le bord de la table de travai l (2), équipé du cutter (8) mobile sur le guidage du cutter (9). Le cutter (8) et le guidage du cutter (9) sont aussi des composants standards. Les bandes d'affiche ( 10) découpées, tombent dans la boîte ( 1 1 ), et sont mises dans la boîte pour le transport ( 12), en carton. La préparation est possible manuellement avec une table de travail, des instruments pour la découpe et des gabarits, pour la mesure. Le dispositif sur la figure 2 est composé d'un cadre avec les prismes triangulaires ( 13). Le cadre est composé de plusieurs morceaux de profil du cadre ( 15) en aluminium spécifiques découpés, percés, usinés. Le cadre est fermé par le couvercle du profil du cadre ( 14), fait d'un deuxième profil spécifique en aluminium. Le couvercle du profil du cadre ( 14) peut s'enlever, ainsi on libère le passage des lamelles ( 16) avec les bandes d'affiche ( 10), pour le retrait et l'insertion dans les prismes triangulaires ( 13). Le retrait et l'insertion des lamelles ( 16) avec les bandes d'affiche ( 10), se fait soit une par une manuellement, soit par groupe de lamelles, en une seule fois automatiquement à l'aide du manipulateur pour le retrait des lamelles ( 17) fixé temporairement sur le cadre du dispositif. Le manipulateur pour le retrait des lamelles ( 17) représenté sur la figure 3 , contient plusieurs paires de galets ( 18) entraînées par le moto-réducteur du manipulateur ( 19). Sur cette figure, les deux premières lamelles ( 16) avec les bandes d'affiche ( 10) sont restées dans les deux premières prismes triangulaires ( 13), bloquées avec les ressorts (20), fait de fil d'acier inoxydable pour ressort. Sur la figure 3 , on peut voir le système de transmission du dispositif avec la règle (2 1 ), faite d'un profil en aluminium standardisé, coupé sur une longueur spécifique, percé, usiné. Sur cette règle sont attachées les bandes flexibles (22), faites soit en tôle d'acier inoxydable, avec une faible épaisseur soit en un autre matériau flexible, résistant à la traction, comme divers plastiques avec armature. La fabrication se fait avec une découpe à l'aide d'un outillage. Les bandes sont enroulées autour des cylindres (23), chacun étant composé de deux pièces identiques (24) faites en plastique injecté dans un moule en deux parties. Les cylindres (23 ) sont fixés sur les axes de rotation (25 ), faits de barre métallique par coupe, perçage, usinage. Ces axes sont positionnés chacun sur deux guidages en rotation (26) standards. Les guidages (26) sont fixés dans le profil du cadre ( 15) avec des vis (27). Sur la figure 4 est représenté la coupe du dispositif où on voit la manière dont est positionnée le prisme triangulaire ( 13), qui a sur son extrémité un élément pointu (28) permettant la liaison du profil triangulaire principal (29) et de l'enveloppe triangulaire transparente (30). Avec sa pointe (31 ), l'élément pointu (28) positionne le prisme triangulaire ( 13) dans le guidage de rotation avec articulation sphérique (32), standard qui est fixé dans le profil du cadre ( 15 ). L'élément pointu (28) est fait de plastique injecté dans un moule en deux parties. Le prisme triangulaire ( 13 ) contient sur l'extrémité opposé un élément creux (33 ), fait aussi en plastique injecté dans un moule en deux parties. L'élément creux (33) l ie le prisme triangulaire ( 13) et l'axe de rotation (25). Le prisme triangulaire est composé de plusieurs éléments montré sur la figure 7, c'est-à-dire l'enveloppe triangulaire transparente (30) faite d'un profil spécifique en plastique transparent et découpé sur une longueur spécifique. Au dessous de l'enveloppe triangulaire transparente (30), pendant l'exposition, se trouve sur chaque face une bande d'affiche ( 10) fixée à l'aide des lamelles ( 16), faites aussi d'un profil spécifique en plastique coupé sur une longueur spécifique, sur lesquelles sont fixés des profils en caoutchouc (34) qui poussent avec leur élasticité la bande d'affiche ( 10) contre la face intérieure de l'enveloppe triangulaire transparente (30). La lamelle ( 16 ) possède aussi deux rainures (36) grâce auxquelles elle est fixée sur le profil triangulaire principal (29 ) fait d'un profil en aluminium spécifique, qui sur une de ses extrémités et sur chaque face, sont fixés des ressorts (20). Entre les arêtes du profil triangulaire principal (29) et les angles, situés à l'intérieur de l'enveloppe triangulaire transparente (30), il y a assez de jeu (37) pour assurer le passage des bandes d'affiche ( 10). Sur la figure 5, on peut voir la liaison entre la bande flexible (22) et le cylindre (23) avec un axe de rotation (25), à l'aide d'une goupille (38), ainsi que la position des autres éléments pendant le retrait et l'insertion des lamelles ( 16) avec la bande d'affiche ( 10). Pendant cette action, le ressort (20) se trouve dans une position permettant le retrait, la ligne discontinue représente sur la figure la position du ressort (20) lorsqu'il bloque la lamelle ( 16) avec la bande d'affiche ( 10). La figure 8 présente le principe de fonctionnement du système de transmission, avec la bande flexible (22) possédant deux bras disjoints (39) liés à la règle (21 ) par ses extrémités, par des vis (40). La bande flexible (22) est enroulée autour du cylindre (23) qui se trouve sur les axes de rotation (25 ), elle est fixée grâce à une goupille (38) sur ce cylindre et sur cet axe. La bande flexible (22) possède un bras médian (41 ) qui est, après enroulement autour du cylindre (23), passée entre deux bras disjoints (39) et avec son extrémité liée à la règle (21 ). La règle (21 ) est entraînée par un vérin électrique (46) qui fait un mouvement linéaire d'aller-retour et qui provoque l'enroulement et le déroulement des bras (39) et (41 ), en le transformant en mouvement de rotation des cylindres (23) et des axes de rotation (25) avec les prismes triangulaires ( 13). Pour les dispositifs de petite dimension représenté par la figure 9, le principe est le même, cependant pour des raisons de prix et de montage, la règle (21 ) en profil d'aluminium, est remplacée par une crémaillère (42) qui entraîne des roues dentées (43 ) avec des axes de rotation (44). Le moto-réducteur (45) entraîne la première roue dentée (43) qui entraîne la crémaillère, celle-ci entraîne toutes les autres roues dentées (43). La crémaillère (42) est un modèle standard en plastique, les roues dentées aussi. La figure 10 représente la première variante du prisme triangulaire ( 13) avec les bandes transparentes (47) supplémentaires, réalisées en film plastique transparent extrudé. Chacune est située entre la bande d'affiche ( 10) et la face intérieure de l'enveloppe triangulaire transparente (30). La bande transparente (47) est fixée par son extrémité à l'extrémité (48) de la lamelle ( 16) avec une vis. Sur la figure 1 1 est représentée la deuxième variante de la prisme triangulaire ( 13), où on peut trouver la bande souple (49) qui remplace la lamelle ( 16). La bande souple (49) est réalisée en film plastique extrudé, et l'ensemble, c'est-à-dire : la bande souple (49), la bande d'affiche ( 10), et la bande transparente (47) sont plaquées contre la face intérieure de l'enveloppe triangulaire transparente (30), grâce aux profils souples (54) collés sur le profil triangulaire principal (29). Le manipulateur (57) contient une bobine de courroie (58 ) motorisée, avec une courroie (55), qui possède sur son extrémité, un élément clé (56). Les figures 12, 13, et 14 illustrent l'élément clé (56) réalisé en matière plastique, ce qui produit un faible coefficient de frottement avec le profil triangulaire principal (29) réalisé en aluminium, lorsqu'il glisse dans celui-ci. Sa forme permet une imbrication dans l'élément glissant (53 ), et leur séparation automatique grâce au ressort (20), à la fin du parcours. L'élément glissant (53 ) est réalisé en matière plastique avec un moulage par injection, à cause de la grande quantité de cet élément. La matière plastique permet un bon glissement dans le profil triangulaire principal (29), et sa forme permet: une imbrication avec l'élément clé (56), ainsi que le blocage, à la fin du parcours, avec le ressort (20). La figure 1 1 montre l'élément clé (56) et l'élément glissant (53 ), coulissant ensemble dans le canal du profil triangulaire principal (29), pendant le changement de la bande d'affiche ( 10). La courroie du prisme qui passe par un galet (52), fixé à l'extrémité du profil triangulaire principal (29), a son extrémité attachée à l'extrémité (50) de la bande souple (49). L'enroulement de la bande souple (49) sur la bobine de bande souple (60), provoque le retrait de la bande d'affiche ( 10), et le déroulement de la bobine de courroie (58). La bobine de bande transparente (59) est utilisée seulement si la bande transparente (47) est présente dans le prisme triangulaire ( 13 ). Lors du remplacement de la bande d'affiche ( 10) par la nouvelle, celle-ci est insérée dans le prisme triangulaire ( 1 3 ) par l'enroulement de la courroie (55 ), ce qui provoque le déroulement de la bande souple (49) qui entraîne avec elle la bande d'affiche ( 10) dans le prisme triangulaire ( 13 ). A la fin du parcours, illustré sur les dessins : 14, 13 et 12, l'élément clé (56) soulève le ressort (20), et permet à l'élément glissant (53) de prendre la position où il se bloque sur le ressort (20), en même temps, le ressort (20) exécute le retrait de l'élément clé (56). Deux cartouches (61 ) sont installées dans le manipulateur (57), la première, avec les nouvelles bandes d'affiche, et la deuxième, vide afin de recevoir les anciennes bandes d'affiche. L'ensemble est couvert d'une plaque transparente (62), en matière plastique, qui protège le matériel des intempéries et permet la visualisation du travail.- Figures 12, 13, and 14 show the phases of nesting of the key element in the sliding element. In Figure 1 is presented the structure of automatic poster preparation in the workshop. The manipulator (1) consisting of standardized components for the manipulators, and the work table (2) where the dimensions and movement of the manipulator (1) are determined relative to the maximum dimension of the poster (3), for which it is planned. We can see the guidance of the manipulator (1) which ensures movement in the three axes of space. The manipulator (1) takes the poster pieces (4), only if it is made up of several pieces, using its suction cups on the manipulator (5) and places them on the work table (2). The work table (2) is covered with suction cups of the work table (6), with which the poster pieces (4) are fixed in good position. Using the adhesive strips (7), the poster pieces (4) are assembled into a single complete poster (3). Using the manipulator (1), the successive movement of the poster (3) is made towards the edge of the table. work l (2), equipped with the cutter (8) movable on the guide of the cutter (9). The cutter (8) and the cutter guide (9) are also standard components. The poster strips (10) cut out, fall into the box (1 1), and are put in the transport box (12), made of cardboard. Preparation is possible manually with a work table, cutting instruments and jigs for measurement. The device in FIG. 2 is composed of a frame with the triangular prisms (13). The frame is composed of several pieces of profile of the frame (15) in specific aluminum cut, drilled, machined. The frame is closed by the frame profile cover (14), made of a second specific aluminum profile. The cover of the frame profile (14) can be removed, thus freeing the passage of the strips (16) with the poster strips (10), for removal and insertion into the triangular prisms (13). The removal and insertion of the slats (16) with the poster strips (10) is done either one by one manually, or by group of slats, all at once automatically using the manipulator for removing the strips (17) temporarily attached to the frame of the device. The manipulator for removing the lamellae (17) shown in FIG. 3 contains several pairs of rollers (18) driven by the gear motor of the manipulator (19). In this figure, the first two strips (16) with the poster strips (10) remained in the first two triangular prisms (13), locked with the springs (20), made of stainless steel wire for spring. In Figure 3, we can see the transmission system of the device with the rule (2 1), made of a standardized aluminum profile, cut to a specific length, drilled, machined. On this rule are attached the flexible bands (22), made either of stainless steel sheet, with a small thickness or of another flexible material, resistant to traction, like various plastics with reinforcement. The manufacturing is done with a cut using a tool. The strips are wrapped around the cylinders (23), each consisting of two identical parts (24) made of injected plastic in a two-part mold. The cylinders (23) are fixed on the axes of rotation (25), made of metal bar by cutting, drilling, machining. These axes are each positioned on two standard rotating guides (26). The guides (26) are fixed in the profile of the frame (15) with screws (27). In Figure 4 is shown the section of the device where we see how is positioned the triangular prism (13), which has at its end a pointed element (28) allowing the connection of the main triangular profile (29) and the transparent triangular envelope (30). With its tip (31), the pointed element (28) positions the triangular prism (13) in the rotation guide with spherical joint (32), standard which is fixed in the profile of the frame (15). The pointed element (28) is made of plastic injected into a two-part mold. The triangular prism (13) contains on the opposite end a hollow element (33), also made of plastic injected into a two-part mold. The hollow element (33) ie the triangular prism (13) and the axis of rotation (25). The triangular prism is composed of several elements shown in Figure 7, that is to say the transparent triangular envelope (30) made of a specific profile in transparent plastic and cut to a specific length. Below the transparent triangular envelope (30), during the exhibition, there is on each side a poster strip (10) fixed with the strips (16), also made of a specific plastic profile cut to a specific length, on which are fixed rubber profiles (34) which push with their elasticity the poster strip (10) against the inside of the transparent triangular envelope (30). The strip (16) also has two grooves (36) by which it is fixed to the main triangular profile (29) made of a specific aluminum profile, which on one of its ends and on each side, are fixed springs ( 20). Between the edges of the main triangular profile (29) and the angles, located inside the transparent triangular envelope (30), there is enough clearance (37) to ensure the passage of the poster strips (10) . In Figure 5, we can see the connection between the flexible strip (22) and the cylinder (23) with an axis of rotation (25), using a pin (38), as well as the position of the others elements during removal and insertion of the slats (16) with the poster strip (10). During this action, the spring (20) is in a position allowing withdrawal, the broken line represents in the figure the position of the spring (20) when it blocks the strip (16) with the poster strip (10) . FIG. 8 shows the operating principle of the transmission system, with the flexible strip (22) having two disjoint arms (39) linked to the rule (21) by its ends, by screws (40). The flexible strip (22) is wound around the cylinder (23) which is located on the axes of rotation (25), it is fixed by means of a pin (38) on this cylinder and on this axis. The flexible strip (22) has a middle arm (41) which is, after winding around the cylinder (23), passed between two separate arms (39) and with its end linked to the rule (21). The rule (21) is driven by an electric cylinder (46) which makes a linear movement back and forth and which causes the winding and unwinding of the arms (39) and (41), transforming it into a rotary movement cylinders (23) and axes of rotation (25) with triangular prisms (13). For the devices of small dimension represented by figure 9, the principle is the same, however for reasons of price and assembly, the rule (21) in aluminum profile, is replaced by a rack (42) which drives toothed wheels (43) with axes of rotation (44). The gear motor (45) drives the first toothed wheel (43) which drives the rack, the latter drives all the other toothed wheels (43). The rack (42) is a standard plastic model, as are the gear wheels. FIG. 10 shows the first variant of the triangular prism (13) with the additional transparent strips (47), made of transparent extruded plastic film. Each is located between the poster strip (10) and the inside of the transparent triangular envelope (30). The transparent strip (47) is fixed by its end to the end (48) of the strip (16) with a screw. In Figure 1 1 is shown the second variant of the triangular prism (13), where we can find the flexible strip (49) which replaces the strip (16). The flexible strip (49) is made of extruded plastic film, and the assembly, that is to say: the flexible strip (49), the poster strip (10), and the transparent strip (47) are pressed against the inside of the transparent triangular casing (30), thanks to the flexible profiles (54) glued to the main triangular profile (29). The manipulator (57) contains a motorized belt reel (58) with a belt (55), which has a key element (56) at its end. Figures 12, 13, and 14 illustrate the key element (56) made of plastic, which produces a low coefficient of friction with the main triangular profile (29) made of aluminum, when it slides therein. Its shape allows nesting in the sliding element (53), and their automatic separation thanks to the spring (20), at the end of the journey. The sliding element (53) is made of plastic material with an injection molding, because of the large quantity of this element. The plastic allows good sliding in the main triangular profile (29), and its shape allows: nesting with the key element (56), as well as blocking, at the end of the journey, with the spring (20). Figure 1 1 shows the key element (56) and the sliding element (53), sliding together in the channel of the main triangular profile (29), during the change of the poster strip (10). The prism belt which passes through a roller (52), fixed to the end of the main triangular profile (29), has its end attached to the end (50) of the flexible strip (49). The winding of the flexible strip (49) on the flexible strip reel (60) causes the removal of the poster strip (10), and the unwinding of the belt reel (58). The transparent tape reel (59) is used only if the transparent tape (47) is present in the triangular prism (13). When replacing the poster strip (10) with the new one, this is inserted into the triangular prism (1 3) by the winding of the belt (55), which causes the unwinding of the flexible strip (49) which carries with it the poster strip (10 ) in the triangular prism (13). At the end of the route, illustrated in the drawings: 14, 13 and 12, the key element (56) lifts the spring (20), and allows the sliding element (53) to assume the position where it is blocked on the spring (20), at the same time, the spring (20) performs the withdrawal of the key element (56). Two cartridges (61) are installed in the manipulator (57), the first with the new poster strips and the second empty to receive the old poster strips. The assembly is covered with a transparent plate (62), made of plastic, which protects the material from the weather and allows viewing of the work.
