Definitions

  • the invention relates to a roller belt display device with two cooperating rollers, one of which rolls up a display belt of the roller belt display device when it is unrolled from the other.
  • roller belt display device is for example in the German utility model DE 20 2009 014 525.5 described.
  • the invention has for its object to provide a roller conveyor display device, in which a defined state of tension of the display band can be achieved during operation of the roller conveyor display device.
  • roller conveyor display device with the features of claim 1.
  • Advantageous embodiments of the inventive roller blind display device are specified in subclaims.
  • each of the two rollers is in each case in communication with an individually controlled drive device and forms a drive roller and a deflection roller is present, which deflects the display belt.
  • a significant advantage of the roller conveyor display device according to the invention is the fact that the state of tension of the display belt can be adjusted in a targeted manner.
  • the roller conveyor display device according to the invention has two Drive rollers, which are driven by means of individually controlled drive means.
  • By such an individual controllability of the drive rollers it is for example possible to take into account the winding state of the drive rollers and, for example, to reduce the winding speed in the winding drive roller during the winding process and to increase the winding speed in the rolling drive roller.
  • roller conveyor display device Another significant advantage of the roller conveyor display device according to the invention is that it is possible with the individually controlled drive means to set and maintain a predetermined bias for the display band.
  • the two drive rollers are arranged below the deflection roller and one of the two drive rollers is arranged between the other drive roller and the deflection roller and an upper drive roller forms and the other of the two drive rollers forms a lower drive roller.
  • the deflection roller is arranged above the two drive rollers, the display belt is pulled by the deflection roller by gravity down, so that always a gravitational tensioning of the display belt is ensured, even if no voltage state is caused by the drive rollers.
  • a gravity-assisted tensioning of the indicating band is achieved in a particularly advantageous manner when the deflection roller deflects the display band by 360 °.
  • the individually controlled drive means comprise stepper motors with which the rotational movement of the drive rollers can be controlled individually in predetermined angular steps;
  • stepper motors make it possible, in a very simple manner, to carry out the control of the display band in a computer-aided manner.
  • the service life of individual display images of the display band can be defined or adjusted individually by a corresponding control of the stepper motors.
  • the roller conveyor display device has a control device which is designed such that it controls the rotational speed of the two individually controlled drive means and
  • the rotational speed of the two drive rollers changed depending on the winding direction, in such a way that in the drive roller, in which the display panel is rolled, the take-up speed is continuously reduced and the other drive roller, in which the display band is unrolled, the take-up speed continuously is increased.
  • the change occurring due to the winding and unwinding of the diameter of the drive roller can be compensated.
  • the roller conveyor display device can automatically go back into operation and the control of the drive rollers taking into account the actual winding condition of the drive rollers can make it, it is considered advantageous if at a predetermined location on the display panel an optically detectable mark is attached, the roller conveyor display device having an associated with the control device optical detection means, the control device is designed such that it with the optical detection means the can be detected on the display belt mounted label, and the control device is also configured such that it detects a detecting the respective winding condition state number to a predetermined starting value and starting from the predetermined starting value after detecting the mounted on the display tape marker for each of the two drive rollers During further operation, the status numbers are counted up or down depending on the direction of rotation of the drive rollers.
  • the control device can achieve a predetermined start state in a very simple manner by moving the display belt until the optical detection device has detected the marking. As soon as a corresponding detection signal from the detection device is present, the control device knows which winding state the two drive rollers have and can carry out the further individual control of the drive devices in a corresponding manner.
  • the optically detectable marking is preferably attached to the beginning of the tape or at the tape end of the display tape. Such an arrangement of the mark makes it easier for the control device to find the mark.
  • the control device only has to move the display band in the direction of the beginning of the tape or the end of the tape until this is reached in order to detect the marking and to be able to reach the starting state.
  • the diameter of the upper drive roller is at least slightly smaller than the diameter of the lower drive roller.
  • the axis of rotation of the two drive rollers and the axis of rotation of the deflection rollers lie in a common plane.
  • each of the two drive rollers is connected to the associated individually controlled drive device in each case by a positively driven in grooves drive belt.
  • FIG. 1 can be seen a roller conveyor display device 10, which includes a lower drive roller 20, an upper drive roller 30 and a deflection roller 40. It can be seen that after setting up the roller conveyor display device for operation, ie in the operating state, the guide roller 40 is arranged above the two drive rollers 20 and 30. To illustrate this, the direction of gravity is in the FIG. 1 marked by an arrow with the reference symbol S.
  • a display band 50 is laid around such that the display band 50 is deflected by 360 °.
  • advertisements in the form of advertising images which are displayed individually by a display band method, may be displayed on the display tape.
  • the display tape 50 is wound on the lower drive roller 20, it is unwound from the upper drive roller 30. Conversely, when the upper drive roller 30 winds up the display belt 50, it is unwound from the lower drive roller 20.
  • the drive device for driving the upper drive roller 30 is in the FIG. 1 designated by the reference numeral 31.
  • the drive means for driving the lower drive roller 20 carries the reference numeral 21.
  • FIG. 1 It can be seen that the two individually controlled drive devices 21 and 31 via control lines 22 and 32 with a control device 60 in connection stand.
  • the control device 60 generates control signals ST1 and ST2 with which it individually controls the two drive devices 21 and 31 and thus effects an individual rotation of the lower drive roller 20 or the upper drive roller 30.
  • the control device 60 will always take into account the respective winding state of the drive rollers during winding and unwinding of the display belt 50 on the upper drive roller 30 and the lower drive roller 20.
  • the controller 60 will continuously reduce the drive speed of a take-up drive roller during take-up and continuously increase the take-up speed of the unwinding drive roller to always maintain the travel speed as well as the tension state of the display belt 50 constant.
  • the two drive devices 21 and 31 are preferably stepper motors which are moved in steps or in increments. This allows the control device 60 to adjust the respective rotational angle of the connecting shafts 23 and 33 in increments or in individual small angular steps.
  • the drive shaft 23 connects the drive shaft 23, the drive means 21 with the lower Drive roller 20 and the upper drive shaft 33, the drive means 31 with the upper drive roller 30th
  • the drive device 31, which drives the upper drive roller 30, is arranged spatially above the drive device 21, with which the lower drive roller 20 is driven.
  • the roller belt display device 10 is caused by the arrangement of the guide roller 40 above the two drive rollers 20 and 30, a tensioning of the display belt 50 by the gravitational force, since the gravitational force pulls the display belt 50 of the guide roller 40 down.
  • the tension can, if desired, be further increased by introducing an additional stress state into the indicating band 50 with the two drive rollers 20 and 30.
  • the size of the state of stress can be caused by the control device 60 by a corresponding control of the two drive rollers 20 and 30 by means of the two individually controlled drive means 21 and 31.
  • control device 60 is in communication with an optical detection device 70, which can optically detect a mark 51 applied to the display belt 50. As soon as the optical detection device has detected the optical marking 51, it generates a corresponding measurement signal M and sends it to the control device 60.
  • the control device 60 thus has the possibility of metrologically detecting the winding state of the display belt 50 by displaying the display band 50 continues until the mark 51 has been detected.
  • the marker 51 is placed at the beginning of the tape or at the tape end of the display tape 50 to facilitate finding the mark. If, for example, the marking 51 is arranged at the beginning of the tape, then the control device 60 must move the display tape only in the direction of the beginning of the tape until the marking 51 is detected.
  • the optical detection device 70 makes it possible for the control device 60 to automatically reach a predetermined start state after a power failure.
  • the control device 60 only has to move the indicating band 50 until the marking 51 is detected.
  • the control device 60 knows the winding state of the two drive rollers 20 and 30 and can carry out the further method of the drive rollers with knowledge of the winding state.
  • the control device 60 after detecting the mark 51 for each of the two drive rollers 20 and 30 each reset the state of winding descriptive state number to a predetermined starting value and count starting from these predetermined starting values, the state numbers depending on the direction of rotation of the drive rollers up or down.
  • the two state numbers indicate in this case the winding state of the respective associated drive roller in the form of a numerical value.
  • control device 60 is designed such that it sets and maintains a predetermined bias voltage by means of the drive means 21 and 31 for the display belt 50.
  • control device 60 is designed such that it can individually define or set the service life of individual display images of the display band 50 by a corresponding control of the drive devices 21 and 31 (eg stepper motors).
  • an upper intermediate shaft 100 which is mechanically coupled to the drive roller 20.
  • the upper intermediate shaft 100 is connected to a lower intermediate shaft 110 via a drive belt 120 in connection.
  • the lower intermediate shaft 110 is driven by the lower drive means 21 and for this purpose set in a rotational movement.
  • the lower intermediate shaft 110 and the upper intermediate shaft 100 respectively grooves 111 and 101, in which the drive belt 120 is forcibly guided along the X direction.
  • Such positive guidance avoids that an angular difference between the rotational angle of the lower intermediate shaft 110 and the respective rotational angle of the upper intermediate shaft 100 can occur.
