  • the new method in particular the loop formation of the door curtain of a roller shutter, preferably a high-speed roller shutter when rolling the door curtain for the closing movement of Rolling doors avoided if the closing movement does not proceed according to plan. It is particularly advantageous that with the new method, a loop formation is avoided even on the winding shaft stocking the door curtain itself or in the region between the winding shaft and the guides for the edge strips of the door curtain, in particular in the region of the inlet funnel.
  • a door curtain of a roller shutter in particular a fast-moving roller shutter, between a first end position "gate open” and a second end position "gate closed”, in which reaching the respective end position detected sensory, then passed a control signal to a control unit of the roll-up door and the following is switched off with a switching signal of the drive for the movement, provided in a new way that between the start and the end of the closing movement of the door curtain inceimpulsly the actual value of the speed of the closing movement is detected and evaluated and in case of deviation of this actual value of a predetermined tolerance window for this speed, the drive of the winding shaft is switched immediately in the step "open".
  • the actual value of the speed of the closing movement is preferably detected mechanically at the door curtain, in an octopo-electronic or magnetic manner.
  • a device which comprises at least one drive for a winding shaft storing the door curtain, a control device and sensors for detecting the end positions of the door curtain, in which a measuring device for detecting the actual Value of the speed of the closing movement of the door curtain is provided, which is connected to a signal line to the control unit.
  • the measuring device is arranged in the range of movement of the door curtain, preferably above the guide slot of one of the door pillars of the roll-up door.
  • the measuring device has a motion detector and a signal converter.
  • the motion detector is located directly on the door curtain.
  • a guide part is provided opposite the motion detector, so that the door curtain rests without slippage on the motion detector.
  • FIG. 1 a roller shutter 4 is shown in a perspective view, on which the device according to the invention is arranged and which can be used for the inventive method.
  • a wall 1 On one side of the wall 1, the roller shutter 4 is arranged in / at the wall opening 2.
  • Sideways of the soffits of the wall opening 2 are his torso columns 10 and 11.
  • a winding shaft 12 in bearings 14, 15 Above the wall opening 2, a winding shaft 12 in bearings 14, 15 is arranged rotatably and drivable.
  • the drive 13 of the winding shaft 12 here consists of a motor and a transmission.
  • a control device 13a Associated with a control device 13a (s. FIG. 2 ).
  • the operating element for the control unit 13a is arranged at normal working height in one of the door columns 10 and 11, respectively. A duplicate of the operating unit is then still on the other side of the wall opening. 2
  • a closing strip 8 is provided, both sides of which end in front of the respective front 18 of the gate columns 10, 11.
  • the guide slot 16 forming components of each gate column 10, 11 terminate above a plane which is predetermined by the upper edge of the wall opening 2, but at a distance from the lower edge of the winding shaft 12. In the FIG. 1 this place / level is the head end 9.
  • the inventive device for performing the method according to the invention in this embodiment shown at least from the drive 13 for the Torbehang 5 stockpiled winding shaft 12, a means of a signal line 17a connected to the drive control unit 13a and sensors for detecting the end position of the door curtain. 5 , which are not shown in the figures, since sensors known per se and their circuitry connection to the drive 13 and the control device 13a are used.
  • a measuring device 23 for detecting the actual value of the speed of the closing movement of the door curtain 5 is provided in this roller door 4.
  • This measuring device 23 is connected to a signal line 17 with the control device 13a.
  • the measuring device 23 is disposed above the head end 9 of the guide slot 16 on the door pillar 10 of the roller shutter 4.
  • a motion detector 25 of the measuring device 23, this FIG. 3 is applied to the door curtain 5, which detected during movement of the door curtain 5 permanently the instantaneous speed of movement of the door curtain, is scanned here.
  • a signal converter 24 which is in operative connection with the motion detector 25.
  • the detected by the motion detector 25 instantaneous movement of the door curtain 5 is converted by the signal converter 24 into a control signal, which is passed via the signal line 17 to the control device 13a.
  • the control signals continuously arriving during the movement of the door curtain are evaluated with respect to a predetermined tolerance window for the speed of the movement of the door curtain. As soon as the speed of the movement of the door curtain falls outside the specified tolerance window, the
  • Control device 13a sent a switching signal to the drive 13 of the roll-up door and as a result, the drive is switched to the step “open door curtain", in particular to the step "door curtain open quickly”.
  • the measuring device 25 is held by a holder 22, which is arranged in the region of the wall side 21 of a door column 10, 11 above the head end 9 of the guide slot 16.
  • the motion detector 25 and the signal converter 24 are arranged on a common base.
  • the motion detector 25 is located on the door curtain 5.
  • a guide member 26 is provided on the other side of the door curtain, see FIG. 2 , which is so close to the door curtain 5, that the door curtain 5 can be moved without slipping on the motion detector 25 along.
  • the guide member 26 is also arranged such that the door curtain 5 is always aligned with its movement "closing" or “opening” with the guide slot 16, no matter how large the winding diameter is straight at the winding shaft 12.
  • the measuring device 23 is provided only on one side of the roller shutter 4, in the region of the column 10, it is within the scope of the invention, when the measuring device 23 together with guide member 26 on the other side of the roller shutter 4, ie is arranged at the gate column 11. However, it is also within the scope of the invention if in each case a measuring device 23 together with associated guide member 26 is provided in the region of both gate columns 10, 11. Such a double arrangement of the measuring device is especially at wide gates of advantages, since an addressed crash situation exist on one side can, which would not be detected quickly enough with only one-sided arrangement of a measuring device fast detection of the impending crash situation.
  • the rotational movement of the winding shaft 12 of the door hanger 5 during rolling up or unrolling of the door hanger 5, in particular for the unwinding of the door hanger 5, for the first time in a roller shutter 4, is the first time.
  • 11 guides 16 procedurally coupled As soon as the movement of the door curtain 5 in the guides 16 deviates from the planned speed of the movement of the door curtain 5, opening of the door curtain takes place relatively quickly, so that crash situations are avoided or crash situations occurring are detected directly in their formation, so that evasive reactions of the door Door curtain 5 (“open door curtain”) can be initiated quickly.
  • a crash situation is understood to mean not only the unwanted contact of an object, a machine or a person with the door curtain 5, but also situations which are directed against a planned movement of the door curtain 5. This is eg an excessive wind load on the door curtain 5 or obstacles or defects in the guides 16 for the edge strips 6, 7 of the door curtain 5.
