Description

Die Erfindung betrifft eine Absturzsicherung für ein Rolltor oder dergleichen zum Angriff an einer motorisch angetriebenen Wickelwelle für das Rolltor mit einem auf der Wickelwelle verdrehfest angeordneten Schneckenrad und einer mit diesem kämmenden Schnecke , die in Achsrichtung verschiebbar gelagert ist und aufgrund fehlerbedingter Drehzahlerhöhung des Schneckenrades von diesem axial gegen einen Anschlag bewegbar ist, so daß die dynamische Selbsthemmung zwischen der Schnecke und dem Schneckenrad die Wickelwelle bremst.The invention relates to a fall protection for a roller shutter or the like for attacking a motor-driven winding shaft for the roller shutter with a worm wheel arranged on the winding shaft in a rotationally fixed manner and a worm meshing therewith, which is displaceably mounted in the axial direction and axially due to an error-related increase in the speed of the worm wheel is movable against a stop, so that the dynamic self-locking between the worm and the worm wheel brakes the winding shaft.

Bei einer bekannten Absturzsicherung dieser Art - AT-B-330.429 - ist deren axial verschiebbar gelagerte Schnecke zum einen über ein mit ihr kämmendes Schneckenrad getrieblich an die Wickelwelle eines Rolltorpanzerns und zum anderen über ein Stirnzahnradpaar getrieblich an ein Antriebsmotoraggregat angeschlossen, das eine Antriebsschnecke treibt, die ihrerseits über ein mit ihr kämmendes Schneckenrad mit der Wickelwelle getrieblich in Verbindung steht. Wenn durch Bruch oder Verschleiß die Schnecken-Schneckenrad-Antriebsverbindung unterbrochen wird, versucht die Wickelwelle unter der Last des Rolltorpanzers im Sinne einer Absturzbewegung über die Betriebsdrehzahl hinaus zu rotieren und übt dabei über das zugeordnete Schneckenrad auf die Schnecke der Absturzsicherung eine Kraft in Richtung deren Axialverschiebeführung aus, ohne die Schnecke wegen des selbsthemmenden Eingriffes zu drehen. Vor Auftreffen auf einen Anschlag, der die Axialverschiebung der Schnecke begrenzt und damit über das zugeordnete Schneckenrad die Rotation der Wickelwelle abbricht, wird die Kopplung der Schnecke an das Antriebsmotoraggregat unterbrochen, was entweder durch ein axiales Verschieben der Zahnräder des Stirnzahnradpaares geschieht, bis diese außer Eingriff sind, oder durch Zerstören einer Sollbruchstelle im Bereich der durch das Stirnzahnradpaar gebildeten Kopplung zwischen der Schnecke und dem Antriebsmotoraggregat. Im ersteren Falle erhöht sich der axiale Verschiebeweg der Schnecke bis zum Anschlag und damit der Fallweg des abstürzenden Rolltorpanzers, im letzteren Falle ergibt sich ein entsprechend höherer Wiederherstellungsaufwand.In a known fall arrest device of this type - AT-B-330.429 - its axially displaceably mounted worm gear is connected on the one hand via a worm wheel meshing with it to the winding shaft of a roller shutter armature and on the other hand via a spur gear pair to a drive motor unit which drives a worm gear, which in turn is connected to the winding shaft via a worm wheel meshing with it. If the worm-worm wheel drive connection is interrupted due to breakage or wear, the winding shaft tries to rotate under the load of the roller shutter curtain in the sense of a fall movement beyond the operating speed and exerts a force on the worm of the fall arrest device via the assigned worm wheel in the direction of its axial displacement without turning the screw because of the self-locking intervention. Before hitting a stop that limits the axial displacement of the screw and thus Aborting the rotation of the winding shaft via the assigned worm wheel, the coupling of the worm to the drive motor unit is interrupted, which is done either by axially shifting the gears of the spur gear pair until they are disengaged, or by destroying a predetermined breaking point in the area formed by the spur gear pair Coupling between the worm and the drive motor unit. In the former case the axial displacement path of the screw increases up to the stop and thus the fall path of the falling roller shutter curtain, in the latter case there is a correspondingly higher restoration effort.

Der Erfindung liegt die Aufgabe zugrunde, eine Absturzeinrichtung der eingangs genannten Art zu schaffen, die schnell und sicher arbeitet, einfach ausgebildet ist und auch bei schon vorhandenen Rolltoren nachträglich angebracht werden kann.The invention has for its object to provide a crash device of the type mentioned, which works quickly and safely, is simple and can also be retrofitted to existing roller doors.

Ausgehend von einer Absturzsicherung mit den eingangs genannten Merkmalen wird diese Aufgabe erfindungsgemäß dadurch gelöst, daß die Schnecke von einem Stellmotor bei dessen Nenndrehzahl in Richtung ihrer Achse auf den Anschlag geschoben und in Anpassung an die Drehbewegung der Wickelwelle im Normalbetrieb gesteuert angetrieben dort nachgeführt gehalten wird.Starting from a fall protection with the features mentioned above, this object is achieved according to the invention in that the worm is pushed by a servomotor at its nominal speed in the direction of its axis onto the stop and is driven in a controlled manner in adaptation to the rotary movement of the winding shaft in normal operation.

Erfindungsgemäß wird die Schnecke der Absturzsicherung, in die das zugeordnete, auf der Wickelwelle verdrehfest angeordnete Schneckenrad - dynamisch selbsthemmend - eingreift, von einem Stellmotor über eine Steuerung so angetrieben, daß die Drehung des Schneckenrades die Schnecke bzw. deren Achse nicht bzw. in eine Richtung nur zu dem Anschlag verschiebt und dort hält. Hierbei wird eine Nenndrehzahl des Stellmotors unterstellt, die nur etwas größer werden kann als diejenige, die erforderlich ist, um im Normalbetrieb die Relativlage der Schnecke bzw. deren Achse am Anschlag gerade einzuhalten. Unter dieser Voraussetzung wird bei sich beim Absturz des Tores schneller drehendem Schneckenrad die Schnecke bzw. deren Achse in Richtung fest auf den Anschlag gedrückt und dort abgebremst in dieser Lage fixiert. Aufgrund der Selbsthemmung zwischen Schnecke und Schneckenrad wird auch diesen und das damit abstürzende Torblatt angehalten. Bei Unterbrechung des Antriebsstranges zur Wickelwelle dreht sich das Schneckenrad schneller, als der gesteuerte Stellmotor mit beschränkter Maximaldrehzahl die Schnecke zurückbewegen kann, um die gleiche Relativlage einzuhalten.According to the worm of the fall protection, in which the assigned worm wheel, which is arranged on the winding shaft in a rotationally fixed manner, engages - dynamically self-locking - is driven by a servomotor via a control so that the rotation of the worm wheel does not move the worm or its axis or in one direction just moved to the stop and stops there. In this case, a nominal speed of the servomotor is assumed, which can only be slightly greater than that which is required in order to maintain the relative position of the screw or its axis at the stop in normal operation. If this happens, the gate will crash faster rotating worm wheel, the worm or its axis is firmly pressed in the direction of the stop and braked there in this position. Due to the self-locking between the worm and worm wheel, this and the door leaf that crashes are also stopped. If the drive train to the winding shaft is interrupted, the worm wheel turns faster than the controlled servomotor with a limited maximum speed can move the worm back to maintain the same relative position.

Damit erhält man eine schnellansprechende und äußerst sicher bremsende Absturzsicherung für Roll- oder dergleichen Tore. Ferner ist die Absturzsicherung einfach aufgebaut und kann bei schon vorhandenen Rolltoren oder dergleichen nachgerüstet werden.This gives you a fast-responding and extremely safe braking fall protection for rolling or similar gates. Furthermore, the fall protection is simple and can be retrofitted to existing roller doors or the like.

Zweckmäßige Ausgestaltungen und Weiterbildungen der Erfindung sind in den Unteransprüchen gekennzeichnet.Expedient refinements and developments of the invention are characterized in the subclaims.

Ein bevorzugtes Ausführungsbeispiel der Erfindung wird nachfolgend unter Bezugnahme auf die Zeichnung näher erläutert, die eine schematische Darstellung der Erfindung zeigt.A preferred embodiment of the invention is explained in more detail below with reference to the drawing, which shows a schematic representation of the invention.

In der Zeichnung ist die Wickelwelle 5, im Schnitt quer zu deren Achse dargestellt. Auf der Wickelwelle 5 mit dem schematisch dargestellten, teilweise abgerollten Rolltor 6 ist ein insgesamt mit 7 bezeichnetes Schneckenrad drehfest angebracht. Dieses Schneckenrad 7 kämmt mit einer Schnecke 8, wobei zwischen diesen Teilen eine dynamische Selbsthemmung vorhanden ist. Die Achse 9 der Schnecke 8 ist mittels zweier Lager 10, 11, beispielsweise üblicher Gleitlager, im übrigen gegen Kippen oder andere Bewegungen als Verschiebungen längs der Achse 9 in vorrichtungs- und/oder torfesten Aufnahmeteilen 12, 13 geführt.In the drawing, the winding shaft 5 is shown in section transverse to its axis. On the winding shaft 5 with the schematically shown, partially unrolled roller door 6, a worm wheel, designated overall by 7, is attached in a rotationally fixed manner. This worm wheel 7 meshes with a worm 8, a dynamic self-locking being present between these parts. The axis 9 of the screw 8 is guided by means of two bearings 10, 11, for example conventional plain bearings, against tilting or other movements as displacements along the axis 9 in device and / or gate-fixed receiving parts 12, 13.

Die Achse 9 der Schnecke 8 ist gemäß Richtungspfeil 14 auf einen gehäusefesten Anschlag 15 zu beweglich. Ferner kann zu Zwecken der Dämpfung noch am Anschlag 15 oder, wie gezeigt, am freien Ende der Achse 9 der Schnecke 8 ein Dämpfungskörper 16, beispielsweise Schaumaluminium angebracht sein.The axis 9 of the screw 8 can be moved in the direction of the arrow 14 towards a stop 15 fixed to the housing. Furthermore, for damping purposes, a damping body 16, for example foam aluminum, can also be attached to the stop 15 or, as shown, to the free end of the axis 9 of the screw 8.

Die Schnecke 8 wird von einem Stellmotor 17 und über eine insgesamt mit 18 bezeichnete Steuerung gesteuert angetrieben. Zu diesem Zweck weist beim wiedergegebenen Ausführungsbeispiel die Achse 9 der Schnecke 8 einen Bund 19 auf, im Bereich dessen beider Enden zwei Ein-Aus-Schalter 20, 21 angeordnet sind, die an die Steuerung 18 angeschlossen sind. Diese steuert ihrerseits über die Ausgangsleitung 22 den Stellmotor 17 so an, daß - im Normalbetrieb des Rolltors - die Achse 9 der Schnecke 8 den Anschlag 15 nicht erreicht. Erst im Absturzfalle, wenn die begrenzte Maximaldrehzahl des Stellmotors 17 nicht ausreicht, eine Regelung durchzuführen, kommt die Achse 9 an dem Anschlag 15 zur Anlage, wodurch das abstürzende Tor gebremst und in dieser abgebremsten Lage gehalten wird.The worm 8 is driven in a controlled manner by a servomotor 17 and by means of a controller designated overall by 18. For this purpose, in the exemplary embodiment shown, the axis 9 of the screw 8 has a collar 19, in the region of whose two ends two on-off switches 20, 21 are arranged, which are connected to the controller 18. This in turn controls the servomotor 17 via the output line 22 so that - in normal operation of the roller door - the axis 9 of the screw 8 does not reach the stop 15. Only in the event of a crash, when the limited maximum speed of the servomotor 17 is not sufficient to carry out regulation, does the axis 9 come to rest against the stop 15, as a result of which the crashing gate is braked and held in this braked position.
