Definitions

  • the invention relates to a device for controlling the Movement of a blackout device, in particular a roller shutter, a roller blind or a slat curtain, by means of a webbing according to the preamble of claim 1.
  • EP-A-0 924 379 such a belt winder known where Hall sensors arranged at an angle used to be two phase-shifted To generate signals that be evaluated in control electronics for determining the direction of rotation of an electric motor.
  • the inventive device with the features of The main claim has the advantage that through dynamic detection an absolute of only two sensor signals Value over the respective position, for example one Roller shutter curtain can be obtained.
  • the absolute position determination is independent of the actual Drive speed. For example, be saved End positions due to a power failure or an unintentional Reset signal cleared, so you can automatically be restored.
  • the evaluation of the Both sensor signals can be implemented in a simple manner.
  • Markings are expediently provided by the sensor means or teeth on the reel and take-up reel or that thus rotating element in drive connection can be scanned and converted into corresponding signals.
  • the signals from the sensor means are preferably counting signals or frequency signals derived therefrom.
  • a simple evaluation option is that the Signals from the sensor means of a quotient formation stage Formation of the ratio values can be fed.
  • the shutdown device at least one comparator to compare the the position values derived from the ratio values at least one predefinable switch-off position value, wherein the shutdown device by the at least one comparator can be actuated.
  • the reel driven by the webbing is convenient the belt deflection roller that is required anyway.
  • FIG. 1 contains a flat belt box 12 a take-up reel 10 for a webbing 11, the belt box 12 is designed so that it is in an existing one Wall recess 13 for a manually operated winding roll can be inserted into a building wall 14.
  • a motor housing 15 is attached to this belt box 12, that this is flat outside the wall recess 13 abuts the building wall 14 and the limits overlaps the wall recess 13 on all four sides, so that the wall recess 13 is completely covered is.
  • the motor housing 15 can also be removed from the belt box 12 be removable.
  • the webbing 11 can by means of the reel 10 in Belt box 12, which rotates substantially centrally there is stored, wound up and unwound and runs from this from a pulley 17 through the motor housing 15 and through a housing opening, not shown outside and then essentially parallel to the building wall 14 up to a not shown, in the usual way trained roller shutter box in which a rotatably mounted Winding shaft for winding and unwinding the roller shutter armor is driven by the webbing 11.
  • the motor housing 15 In the middle of the motor housing 15 there is a reduction gear 18 arranged by an electrical Drive motor 19 is driven.
  • the drive motor 19 drives a first gear wheel via a worm wheel 20 21, this a second gear 22 and this the take-up reel 10 on.
  • the take-up reel 10 a ring gear 23.
  • existing pulley 17 are ferromagnetic or permanent magnetic Elements 24 embedded in the area of the outer circumference.
  • the deflection roller rotates 17, and the elements 24 pass a first one Sensor 25 in which each of these elements 24 generates a signal.
  • the sensor can be designed as a reed switch his.
  • a second sensor 26, also according to DE-A-44 14 280 can be formed is in the area of the teeth the second gear 22 arranged so that the Rotation of this gear 22 each tooth a signal in second sensor 26 generated.
  • the two sensors 25, 26 are connected to an electronic control device 27, which housed in the lower area of the motor housing 15 is.
  • a DC motor Drive motor 19 are not shown Batteries, for example in the upper area of the motor housing 15, which are also designed as rechargeable batteries could be. Alternatively or additionally there is also one Power supply possible via a connection cable.
  • the operation of the drive motor 19 or the electronic Control device 27 takes place via operating elements, not shown on the technological of the building wall 14 flat outside of the motor housing 15.
  • the two sensors 25, 26 have a quotient formation level 28 or a divider connected.
  • the output of this quotient formation stage 28 is one each Input of two comparators 29, 30 for the two end positions connected.
  • the corresponding end positions, where the switch-off is to take place, can be made via comparison inputs 31, 32 can be specified.
  • the outputs of the Comparators 29, 30 control one via an OR gate 33 Switch 34 in the circuit of the drive motor 19th
  • the one shown in FIG Circuit also implemented by a microcontroller or the corresponding functions will be additional through an already existing microcontroller realized.
  • the basic idea of the present invention is now that in every webbing position and therefore in every position the shutter curtain a certain speed ratio between the deflection roller 17 and the take-up reel 10 is present.
  • the speed of the deflection roller 17 is in fixed relationship to the belt speed.
  • This Speed ratio can thus the webbing position or the position of the roller shutter curtain or another the webbing driven blackout device, such as a blind or a slat curtain.
  • the diameter of the webbing 35 equal to the diameter of the pulley 17 and further assume that the diameter of the take-up reel 10 three and a half times the diameter of the corresponds to second gear 22, is under the further requirement that the number of teeth of the second Gear 22 of the number of elements 24 of the guide roller 17 corresponds to the speed ratio of the speed of the Deflection roller 17 for the speed of the second gear wheel 22 1: 3.5.
  • the speed ratio is the lower one End position of the roller shutter curtain reached. If you now continues as an example assuming that in the upper End position of the roller shutter curtain the diameter of the webbing roll 35 3.5 times the diameter of the Deflection roller 17, then the speed ratio is 1: 1.
  • this speed ratio becomes formed by the signals f1 of the first Sensor 25 by the signals f2 of the second sensor 26 be divided.
  • the comparators 29, 30 are used as comparison values the lower cut-off value Au and the upper one Switch-off value Ao specified that the present there Speed ratio.
  • the one created in each Output signal of the comparators 29, 30 leads to opening the switch 34 and thus to switch off the drive motor 19.
  • the switchover required when switching off the direction of rotation of the drive motor can according to state of the art to ensure that when the drive motor is switched on again a switching command or a radio signal the opposite Drive direction is present.
  • the restart the drive motor can be by manual or wireless Closing the switch 34 take place.
  • the comparison values Au and Ao can be stored, for example by the fact that each in the Quotient formation stage 28 values temporarily stored become. In a learning mode you can then lower switch-off position the last saved value as Value Au and accordingly in the upper switch-off position the value Ao can be stored as a comparison value. This can be done manually or automatically.
  • the second sensor 26 another gear or directly the sprocket of the take-up reel Scan 10, or vary the number of elements 24 to be scanned in or on the deflection roller 17.
