Definitions

  • the invention relates to a device for displaying announcements, in particular prices in numerical form.
  • AT-B-388253 is a generic device for displaying announcements, in particular prices in numerical form, previously known.
  • a display tape is provided for each digit of a price, which is partially rolled up on two winding rollers arranged parallel to each other and whose surface between the winding rollers forms the display surface.
  • Each winding roller is designed as a hollow roller and is connected via an electromagnetic clutch to a drive shaft which is connected to the drive pinion of a central drive motor via chain wheels and chains arranged at the ends thereof.
  • four display tapes with four winding rollers each running on one plane and parallel to one another are provided on a display device for four digit positions.
  • An adjustment of the numerical display of a display tape is carried out by driving the central drive motor and actuating the electromagnetic clutch of the winding roller on which the respective display tape must be wound in order to change the numerical display.
  • a braking bearing is assigned to each winding roller, so that the display tape remains tensioned on a winding roller during winding.
  • the invention is therefore based on the object to provide a device for displaying announcements of the generic type, which is structurally simple and in which the wound on the winding rollers and unwound from these display tape is constantly kept under constant belt tension.
  • a drive motor is assigned to each winding roller, whereby the technical and constructive outlay of the display device is significantly reduced. Furthermore, the drive motor winding the display tape onto the one winding roller is operated at a higher speed than the drive motor unwinding the display tape from the other winding roller. As a result, a functionally advantageous operating state is achieved, which is characterized in that the faster rotating winding drive motor and the slower rotating unwinding drive motor are forced into a synchronous operation at constant belt tension via the winding or unwinding display tape.
  • the unwinding drive motor is operated at a lower speed than the winding motor.
  • the winding drive motor thus pulls the unwinding drive motor over the winding roller assigned to it via the winding roller assigned to it and the display tape and thus keeps the display tape in synchronous operation with constant belt tension.
  • the two drive motors are switched off simultaneously.
  • the display band remains taut because the possible overrun of the two drive motors by the display band is necessarily the same.
  • the drive motors are designed as electric motors, the voltage of which is regulated to effect the desired different drive speeds.
  • the voltage of the electric motor winding the display tape onto a winding roller is the supply voltage of the operating network and the voltage of the electric motor unwinding the display tape from the other winding roller is lower than the supply voltage of the operating network.
  • the two electric motors are DC motors connected in parallel, in particular geared motors, to each of which resistors are connected in series and diodes connected in parallel to them with an opposite blocking direction. By simply reversing the polarity of the supply voltage of the two DC motors, one or the other winding roller can be switched as a winding roller and the other as a winding winding roller.
  • the use of geared motors with high gear ratios prevents a return of the winding rollers, whereby a constant sliver tension is achieved at a standstill.
  • the electric motors are designed in particular as geared motors built into the winding rollers.
  • the device comprises a box-shaped housing 1, in which two groups of three winding units 2 each are mounted on the front side and on the rear side, not shown, each of which is formed from an upper winding roller 3 and a lower winding roller 4 arranged at a distance from this, on which a display tape 5, in particular a plastic tape made of translucent or transparent material, is wound with its two ends or wound up and unwound. Above each group of winding units 2 there are display areas 6 for product names such as "Diesel" and "Super”. The symbols on the individual display tapes, in particular numbers, are not shown.
  • the housing 1 comprises between each winding unit 2 or between two winding rollers 3, 3' arranged one behind the other in an axis Side plate 10, on which for each winding roller 3, 3 'a bearing ring 12 with a bronze spring washer 13 interposed, which also serves to protect the supply cable to the motor 8, is flanged.
  • the flanges are carried out by screw connection elements 11.
  • the peripheral surfaces of the bearing rings 12 are circular and are arranged concentrically to the axis and guide the tubular winding rollers 3, 3 ', which are provided at the front end with flanges 14, which define a lateral limitation for each form wound display tape 5.
  • a geared motor 8 is flanged onto a bearing ring 12 by means of a motor plate 9 and several stud bolts 15, so that the geared motor 8 is carried by the side plates 10 of the housing 1.
  • a driving disk 17 is placed in a rotationally fixed manner, which exactly fills the inside diameter of the tubular winding roller 3, 3 'with its outer surface.
  • the drive plate 17 is positively connected to the tubular winding roller 3, 3 'via stud screws 18.
  • the associated tubular winding roller 3, 3 ′ is thus driven via the driving disk 17, which can be rotated on the peripheral surfaces of two bearing rings 12 and is guided on the side plates 10 via the bronze spring washers 13.
  • 2 and 3 tension rods 19 and spacer tubes 20 and in the vertical direction variable connecting struts 21 are provided for connecting the individual side plates 10, which can be seen in FIGS. 1, 4 and 5.
  • both side plates 10 are at a distance from the axes of the two winding rollers 3, 3 'deflection rollers 22 with lateral guide bushes 23, around which the display tape 5 is guided and between which the display tape 5 is freely visible.
  • Each of the display tapes 5 drawn off from the upper side of the winding rollers 3, 4 are provided with lateral perforations 24 which circulate in the area of a tape scan 25 shown on the lower side plate 10 in FIG. 5 and thereby the exact positioning of the Display tape 5 and thus the character located on this is set.
  • the plastic display tapes 5 run in a manner not shown behind plexiglass covers held in the housing 1 and are illuminated from the inside via TL tubes 26 attached between the front and rear winding units 2.
  • the display tapes 5 of the front and rear winding units 2 are each guided behind the front or rear plexiglass cover.
  • the upper and lower winding rollers 3, 4 of the front and rear winding units 2 are each with their axes on a common horizontal plane.
  • the axes of the upper and lower winding rollers 3, 4; 3 ′′, 4 ′′ are offset vertically from one another and the display tape 5, of the rear winding unit 2 ′ provided with a larger center distance, is guided forward and extends parallel to and at a short distance in front of the display belt 5 of the front winding unit 2. Additional deflection rollers 22 'are therefore required for the winding belt 5'.
  • the front display tape 5 'of the rear winding unit 2' is completely or partially transparent, so that the symbols located on the rear display tape 5 of the front winding unit 2 can be seen through the front display belt 5 '.
  • the geared motors 8, 8 ' are DC motors, to which in each case resistors 27, 27 'are connected in series and to them diodes 28, 28' connected in parallel with the reverse blocking direction.
  • diode 28 of the geared motor 8 is conductive, whereas the diode 28 'of the geared motor 8' blocks.
  • the geared motor 8 is thus operated with the supply voltage of the operating network applied to the connection points 29, 30.
  • the geared motor 8 ' is operated only with the supply voltage of the operating network via the resistor 27', ie with a lower voltage, so that the drive speed of the geared motor 8 'is lower than the drive speed of the geared motor 8.
  • the geared motor 8, the z. B. is arranged in the upper winding roller 3 of a winding unit 2, winds up the associated display tape 5, whereas the then arranged in the lower winding roller 4 of the same winding unit 2 gear motor 8 'unwinds the display tape 5 at a lower speed, so that the display tape 5 constantly is kept under tension.
  • the two geared motors 8,8 ' are operated in opposite directions. After the desired position of the display tape 5 has been reached, both geared motors 8, 8 'are switched off by a manual control device or a microprocessor circuit.
