Definitions

  • the present invention relates to a device for the display of posters and signage.
  • the poster presentation by triangular prisms, arranged one alongside the other periodically rotating and presenting three posters, is one of the panels that require the biggest investments in time and means for the preparation of posters to exhibit, as well as the production of panels.
  • the usual poster change system consists of several stages. We are first, by truck to the exhibition site where, manually, we remove the aluminum slats which form triangular prisms on which are glued poster strips. The slats are stored in the truck and then taken to the workshop, where they are unloaded, then soaked in tubs filled with water hot and scalded to facilitate the removal of the old poster strips to using a scraper.
  • the strips, cleaned, are placed on a template and form a surface allowing to stick the poster. Bonding is done in a traditional way with a broom. Then it is necessary to wait until the posters are dry to allow cutting and separation of the slats. Between the slats there are a space of approximately 5 mm, the part of the poster in this space must be removed by two cuts between the slats, by strip, 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 disposed of initial position. This process involves a waste of time and the risk of injury are important since the work is done at height, manually, with sharp parts and tools.
  • the weight of the slats making up the three posters of a panel is about 140 kg.
  • this method is the most used since it is the most effective so far.
  • aesthetic problems because of the preparation complex manual, the result being very dependent on the quality of work of the worker.
  • the strips come off because they have been badly glued on some slats.
  • the system is more profitable if we have to change the three posters because it is necessary to remove the prisms for changing three, two, or a single poster.
  • Setting place of the slats takes time since it is done horizontally, which represents a risk of breakage or deformation of the slats due to the length, and especially if only one worker performs the maneuver.
  • their handling reduces their transparency.
  • the means by which the slats are linked to the profiles in aluminum is guaranteed over the entire length of the edges which reduces the surface area of the poster between the prisms, so the poster loses its aesthetic side because of the large black lines between the triangular prisms. This change process poster requires some skill on the part of the worker to cut the bands which also leads to waste.
  • the device according to the invention for the presentation of posters or signs is presents of the type comprising a frame composed of several profile pieces and triangular prisms positioned vertically next to each other in the frame, said prisms exposing their faces by synchronized periodic rotation, with periodic change of direction of rotation, using a appropriate transmission, the posters being cut into strips, the strips of a poster being supported by the faces of the prisms which are exposed in synchronization, the installation of poster strips on the faces of the prisms and the removal of said strips of posters on the faces of the prisms being produced individually or collectively by scrolling between one face of the triangular profile principal constituting the structure of the prisms and an interior face of an envelope transparent surrounding each prism, installation and removal being carried out using a manipulator temporarily attached to the frame, the poster strips being attached to the upper end of the guide means with which they are associated for the operation of fitting or depositing on the face of the prisms, these guide means being in connection with the manipulator drive system.
  • the present invention therefore proposes that the guide means comprise a strip flexible positioned on one side of the poster strip, the two strips then being strung between the face of the main triangular profile and the inner face of the transparent envelope using a belt passing over a return roller and inside the main triangular profile so that the flexible strip after threading, is positioned between the surface of the main triangular profile and the strip poster.
  • the change of the poster strips is done manually or automatically at using a manipulator.
  • the key element fixed on the belt, wound on the belt spool, is nested in the element sliding 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 strip transparent respectively on the motorized flexible strip coil and the coil transparent tape, also motorized, which are in the manipulator.
  • the winding of the strips i.e. the removal of the poster strip, causes the unwinding of the belt reel.
  • the insertion is done by the reverse process winding of the motorized belt reel, which causes the unwinding strips and the entry of the new poster strip in the triangular prism.
  • the manipulator In end of the journey, the key element is automatically ejected by the spring, which blocks the sliding element.
  • the manipulator has two cartridges, one for storage of new poster strips which will be inserted into the prisms triangular, and the other empty, for loading the old tapes poster.
  • the manipulator can be used during inclement weather, since it is covered by a transparent plate, which protects the poster strips, and allows a visualization of operations. In the manual case, it is enough to have a belt with a key element for the change of poster.
  • 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 exposure sequence and the period of time desired. With such a rotation, it is possible to expose two or three faces with the sequence and the time chosen exhibition. Because of the periodic rotation, with the change of the direction of periodic rotation, there is no need to use a transmission mechanism that allows the always rotating in the same direction, i.e. the transmission mechanism is simplified.
  • the transmission is carried out with flexible bands, each composed of two disjointed arms, linked to the ruler 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 an arm median which once wrapped around the cylinder passes in the middle of the two disjoint arms and with which it is linked to the rule.
  • the flexible strips are fixed on the ruler which extends almost over the entire length of the frame profile, and wrapped around the cylinders with the axes of rotation, on which they are also fixed, and allow the transformation of the linear movement of the rule by the winding and unwinding of arm, in a rotational movement of the cylinders with the axes of rotation.
  • Each axis of rotation is positioned on two rotation guides with ball joint, and on each axis of rotation is positioned a triangular prism.
  • This transmission process with the flexible bands suitable for the device of large dimension from the price of parts and assembly.
  • the most favorable variant is that of the transmission where the linear movement is transformed into movement of rotation 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 triangular prisms because the rule entails all the flexible bands fixed on it.
  • the rule is driven by an electric cylinder or, for small devices, by a gear motor.
  • the invention provides several advantages: transport and handling concerning the change of displays, 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, since it is enough to reconstitute the poster from the initial poster pieces by a collage using adhesive strips, which is immediate, moreover, there is no need to wait drying for cutting. There is no need to apply any adhesive film or glue for fixing the poster strips to the prisms, and also to rewind the poster strips for installation. 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.
  • the system offers two possibilities, for preparation and for poster 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 that adapts to various applications, for example: advertising panels of 3x4 m 2 or 3x8 m 2 and more, small panels for buses, trains, agencies, stores, or signage for roads.
  • FIG. 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 the displacement of the manipulator (1) are determined in relation to the maximum size of the poster (3), for which it is planned.
  • the manipulator (1) takes the pieces poster (4), only if it is composed of several pieces, using its suction cups of the manipulator (5) and place 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 the correct position. Using the adhesive strips (7), we assemble the poster pieces (4) into one complete poster (3).
  • the device in FIG. 2 is composed of a frame with the triangular prisms (13).
  • the frame is made up of several pieces of the frame profile (15) in specific aluminum cut, drilled, machined.
  • the frame is closed by 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 slats (16) with poster strips (10), for removal and insertion into triangular prisms (13).
  • the removal and insertion of the strips (16) with the poster strips (10) is done either by one manually, or by group of slats, all at once automatically at using the manipulator to remove the slats (17) temporarily fixed on the frame of the device.
  • Figure 3 shows the principle operating 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 band (22) is wound around the cylinder (23) which is on the axes of rotation (25), it is fixed with a pin (38) on this cylinder and on this axis.
  • the flexible band (22) has a middle arm (41) which is, after winding around the cylinder (23), passed between two disjointed arms (39) and with its end linked to the rule (21).
  • Rule (21) is driven by an electric actuator (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 movement of rotation of cylinders (23) and axes of rotation (25) with triangular prisms (13).
  • FIG. 4 shows the principle of 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, it drives all other gears (43).
  • the rack (42) is a standard plastic model, cogwheels too.
  • Figure 5 shows the first variant of the triangular prism (13) with the additional transparent strips (47), made of extruded transparent plastic film. Each is located between the poster strip (10) and the inner face of the transparent triangular envelope (30).
  • the band transparent (47) is fixed by its end to the end (48) of the strip (16) with a screw.
  • FIG 6 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 band (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 inner face of the transparent triangular casing (30), thanks to the flexible profiles (54) glued on the main triangular profile (29).
  • the manipulator (57) contains a belt reel (58) motorized, with a belt (55), which has on its end, a key element (56).
  • the Figures 7, 8, and 9 illustrate the key element (56) made of plastic, which produces a low coefficient of friction with the main triangular profile (29) produced in aluminum, when it slides into it.
  • the sliding element (53) is made of plastic material with injection molding, because of the large amount of this element.
  • the plastic allows good sliding in the main triangular profile (29), and its shape allows: nesting with the element key (56), as well as the blocking, at the end of the journey, with the spring (20).
  • Figure 11 shows the key element (56) and the sliding element (53), sliding together in the profile channel main triangular (29), during the change of the poster strip (10).
  • the belt of the prism 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).
  • Tape reel transparent (59) is used only if the transparent strip (47) is present in the triangular prism (13).
  • this is inserted into the triangular prism (13) by the winding of the belt (55), this which causes the unwinding of the flexible strip (49) which carries with it the strip poster (10) in the triangular prism (13).
  • the key element (56) lifts the spring (20), and allows the sliding element (53) to take the position where it locks on the spring (20), at the same time, the spring (20) performs removal of the key member (56).
  • Two cartridges (61) are installed in the manipulator (57), the first, with the new poster strips, and the second, empty in order to receive the old poster strips. The whole is covered with a plate transparent (62), made of plastic, which protects the material from the weather and allows viewing the work.
  • the device is suitable for the presentation of all kinds of posters and signage, more particularly for advertising posters which frequently require a change of poster.
