Definitions

  • the present invention relates to a device for the successive presentation of messages, of the type comprising a flexible film E serving as a support for messages and the ends of which are fixed and can be wound or unwound on two rotary lower cylinders A, B with axes parallel, located at a height close to each other and coupled to a drive member making it possible to return a cylinder A, B when the other is debtor and vice versa, means being further provided for organizing the scrolling film and exposure times, the above film passing around a third cylinder C rotatably mounted above the two above cylinders, so that the two sections of film suspended on either side of this third cylinder , balance each other, the aforesaid drive member comprising at least one motor M coupled to the two above-mentioned lower cylinders A, B by means of at least one transmission element 9 and two respective clutches fs 4-7, 8, 6, preferably electromagnetic.
  • This device is intended in particular for the presentation of traffic information messages or advertising posters.
  • Patent FR-A-385347 discloses a device for successive presentation of messages of the type mentioned above in which the rotation of the coils is operated by a crank system with lug engagement in a single direction of rotation.
  • patent FR-A-1037038 it is known to carry out the drive of the cylinders or coils by a worm system with alternative control.
  • a device for the successive presentation of messages of the type comprising a flexible film E serving as a support for the messages and the ends of which are fixed and can be wound or unwound on two rotary lower cylinders A, B with parallel axes, located at a height close to each other and coupled to a drive member making it possible to make a cylinder A, B receiver when the other is debtor and vice versa, means being furthermore provided for organizing the running of the film and the duration of exhibitions, the above film passing around a third cylinder C rotatably mounted above the two aforementioned cylinders, so that the two sections of film suspended on either side other of this third cylinder, balance each other, the aforesaid drive member comprising at least one motor M coupled to the two aforementioned lower cylinders A, B by means of at least one transmission element 9 and two gear respective yages 4-7, 8, 6, preferably electromagnetic, device characterized in that the stop of the movement is obtained by stopping the motor M and by putting the two
  • the device according to the invention allows a fully automatic presentation of a series of messages of any size, with stops of adjustable duration in front of a presentation area or viewing space.
  • the device according to the invention comprises a strip or a plastic film (E) serving as a support for several messages or advertising posters which is wound and fixed, by each of its ends to each of the two cylinders lower (A) and (B), along a route Ta, Tc1, Tc2, Tb, so that a complete message, correctly framed, appears in the viewing space (D).
  • E a strip or a plastic film
  • the entire device is physically in perfect equilibrium, without the intervention of any stabilization or braking system: the strip length Ta ⁇ Tc1 is indeed exactly equal to the length Tc2-Tb, therefore weighing of equal weight on each side of the upper cylinder (C).
  • Each cylinder (A) and (B) is integral by its axis with an electromagnet type solenoid (4) and (6) as shown in FIG. 3. These solenoids can be supplied electrically via a circular contact (3) and (5) rubbing against a carbon connected to the electronic control unit.
  • the solenoid When energized, the solenoid produces a magnetic field which attracts towards (4) a ferrous disc (7) which is connected to the drive motor (M) ( Figure 2) by any conventional transmission mode (9) (chain , belt), gear or gimbals.
  • the electronic programmer feeds the electromagnet (4) via the carbon (3) and at the same time feeds the motor (M) which starts to turn counterclockwise. Due to the magnetic field produced by the solenoid (4) the transmission disc (7) is then stuck strongly to it and driven by the motor (M) transmits its movement to the cylinder (A). During this operation, the solenoid (6) is not supplied and the cylinder (B) is therefore freewheeling and can therefore turn clockwise quite freely since it is not attached to the motor (M) via the disc. (8). In this case, the message film (E) descends behind the viewing space (D). This descent is self-braked by the weight of the rising poster Tb-Tc1 not visible in the viewing space.
  • a mechanical, optical or magnetic proximity detector (depending on the embodiment chosen), correctly placed (but not shown in the diagram because of the conventional type) sends a signal to the electronic unit which by means of a relay will cut the power supply to the motor (M) and the solenoid (6).
  • another relay will supply the solenoid (6) and replenish the solenoid (4) which will stick to the transmission discs (8) and (7) which thus become integral with each other, connected as they are by the means transmission passing through the engine (M).
  • the set of poster film cylinders is then perfectly immobilized and once again in balance.
  • the electronic unit After a preset exposure time, the electronic unit will cut the power to the two solenoids (4) and (6). Simultaneously, another relay of the electronic unit will control the supply of the motor (M) as well as that of the solenoid (6) via the carbon (5), this if we place our in a case of inversion of the direction of scrolling of the poster strip.
  • the solenoid (4) is then not supplied.
  • the cylinder (A) is therefore free and can therefore unroll the length of poster strip required by the rotation of the cylinder (B). In this case, the poster, in the viewing space is therefore rising.
  • the proximity detector specified above, again sends a signal to the electronic unit which will cut the power to the motor (M) and the solenoid (6).
  • the electrical supply of the electronic regulation system ( Figure 4) and of the motor (M) can be done either by 220 Volts 50 Hz current (10) or by 12 Volts direct current (11) it is then simply necessary to close the switch (12).
  • the electronic unit is made up of three and five stage relays of the classic type. These relays receive their command from three correctly located proximity switches (13), one for stopping and reversing the last rising poster, another for stopping and reversing the last falling poster. and finally the third used to stop and perfectly frame the intermediate posters.
  • the lamps (14) and the proximity detectors (13) are placed on either side of the strip of posters which is then very slightly perforated in certain correctly located places. in order to obtain a correct stop of each poster in front of the viewing space.
  • the poster strip is mechanically driven by a single motor (M) always rotating in the same direction (in the embodiment shown in FIG. 1, in the counterclockwise direction, but the opposite direction may also be suitable in another case of realization of the present invention).
  • the upward movement of the poster strip is obtained by supplying the solenoid (6) integral with the cylinder (B), the solenoid (4) of the cylinder (A) then not being supplied.
  • the solenoid (4) which is supplied, while the solenoid (6) is not, thus ensuring the desired dissociation between the cylinder (B) and the transmission disc (8).
  • the proximity detector concerned When framing a poster in the viewing space, the proximity detector concerned sends a signal which triggers the start of the timer (15), the two solenoids (4) and (6) being during all the timers always powered.
  • the two cylinders (A) and (B) are therefore made integral by means of the transmission mode (9) ( Figure 2). This operation, in accordance with the present invention, ensures perfect immobility of the assembly during the entire exposure time, eliminating the need for an additional braking system, the engine playing only a pivotal role.
  • the display can be done in double face, without modifying any of the balances established by the present invention.
  • the device according to the present invention can be used whenever it is necessary to obtain to regulate the tension of a fabric or cable.
