Abstract

The driveshaft (10) has an insert (11) with an axially movable friction plate (12) against which two parallel pressure plates (20,22) having limited relative rotation are brought to bear by the spring-biased armature (18) of an electromagnet (17) when the latter is de-energised. The pressure plates have elevations with sloped edges on the faces turned towards each other, so that their relative rotation causes the elevations to slide over each other and to force the pressure plates apart.

Description

Die Erfindung betrifft eine Sicherungsvorrichtung gegen den Absturz von über eine Antriebswelle motorisch auf- und abbewegbaren Objekten, beispielsweise Rolltoren.The invention relates to a safety device against the fall of objects that can be moved up and down by means of a drive shaft, for example roller doors.

Bislang wurden auf- und abbewegbare Objekte in der Regel durch selbsthemmende Getriebe oder durch Federeinrichtungen gegen einen Absturz bei einem Motor- oder Getriebedefekt gesichert. In vielen Anwendungsbereichen, beispielsweise Rolltoren, werden diese Maßnahmen jedoch als unzureichend angesehen. Es sind daher bereits Sicherungsvorrichtungen in Form einer elektromagnetisch betätigbaren Klauenkupplung, die nicht im Antriebsteil für das Objekt integriert ist sondern eine gesonderte Sicherungsvorrichtung bildet, vorgeschlagen worden. Diese Sicherungsvorrichtungen haben jedoch den Nachteil, daß insbesondere bei schweren auf- und abbewegbaren Objekten von der Klauenkupplung schlagartig hohe Kräfte aufgenommen werden müssen, die zu einer starken Materialbelastung der Kupplungsteile führen.Up to now, objects that can be moved up and down have generally been secured against falling in the event of a motor or transmission defect using self-locking gears or spring devices. In many areas of application, for example roller shutters, these measures are considered inadequate. Therefore, safety devices in the form of an electromagnetically actuable claw coupling, which is not integrated in the drive part for the object but forms a separate safety device, have already been proposed. However, these securing devices have the disadvantage that, particularly in the case of heavy objects that can be moved up and down, suddenly high forces have to be absorbed by the claw coupling, which lead to a high material load on the coupling parts.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Sicherungsvorrichtung gegen einen Absturz insbesondere von Rolltoren zu schaffen, die einen zuverlässigen Schutz unter Vermeidung der obengenannten Nachteile gewährleistet.The invention is therefore based on the object of providing a safety device against falling, in particular of rolling shutters, which ensures reliable protection while avoiding the disadvantages mentioned above.

Diese Aufgabe wird bei einer gattungsgemäßen Sicherungsvorrichtung erfindungsgemäß durch die kennzeichnenden Merkmale des Anspruches 1 gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der abhängigen Ansprüche.This object is achieved in a generic safety device according to the invention by the characterizing features of claim 1. Advantageous embodiments of the invention are the subject of the dependent claims.

Anstelle der bislang vorgeschlagenen Klauenkupplung tritt hier also eine Reibkupplung, die ein Bremsmoment auf die Antriebswelle für das auf- und abbewegbare Objekt ausübt. Bei Reibkupplungen ist die Kraftaufnahme beim Einkuppeln sanfter und damit materialschonender als beim Formschluß einer Klauenkupplung. Zur Gewährleistung eines ausreichend hohen Bremsmomentes wird dabei der Druckteil nicht nur elektromagnetisch gegenüber der Trägerplatte verschoben, sondern zusätzlich durch zwischen dem Gehäuse, in dem die Reibscheibe angeordnet ist, und der Trägerplatte angeordneten, eine Federkraft ausübenden Elementen gegen die Reibscheibe gepreßt. Dabei können der Druckteil und die Reibscheibe an den gegenseitigen Berührungsflächen jeweils mit einem Reibbelag versehen sein, die den Reibschluß verbessern und das Material von Reibscheibe und Druckteil schonen. Der Druckteil ist von zwei parallelen, begrenzt gegeneinander verdrehbaren Druckscheiben gebildet, die auf ihren einander zugewandten Seiten jeweils rampenförmige Erhebungen aufweisen, die durch die beim Anpressen des Druckteils gegen die Reibscheibe erfolgende relative Verdrehung der beiden Druckplatten aneinander entlanggleiten und dabei die beiden Druckplatten in axialer Richtung auseinanderdrücken, wodurch sich die von den zwischen Gehäuse und Trägerplatte angreifenden Elementen und ausgeübte Federkraft damit das von der Reibkupplung erzeugte Bremsmoment verstärkt. Sobald die Absturzsicherung also aktiviert wird, und das Druckteil gegen die Reibscheibe in Anlage gelangt, erfolgt ein Verdrehen der beiden Druckscheiben und dadurch eine zusätzliche Verstärkung des auf die Antriebswelle ausgeübten Bremsmoments. Der Druckteil der Reibkupplung kann dabei unter dem Einfluß mindestens eines Elektromagneten gegenüber der Trägerplatte in axialer Richtung gegen die Reibscheibe verschiebbar sein und in umgekehrter Richtung unter Vorspannung mindestens einer Feder stehen, wobei die Stromversorgung des mindestens einen Elektromagneten durch eine Schalteinrichtung gesteuert ist, die eine Impulsvergleichsstufe umfaßt, die einen ersten Eingang für eine der Drehzahl der Antriebswelle entsprechende erste Impulsfolge und einen zweiten Eingang für eine der Drehzahl des Antriebsmotors entsprechende zweite Impulsfolge aufweist und deren Ausgangssignal die Unterbrechung der Stromversorgung steuert. Diese Schalteinrichtung für die Stromversorgung erfordert wenig Aufwand und nur geringe Eingriffe in ein vorhandenes Antriebssystem, so daß auch bei Verwendung dieser Schalteinrichtung ein nachträglicher Einbau der Sicherungsvorrichtung keine Schwierigkeiten bereitet. Die Reibscheibe kann hierbei an ihrem Umfang mit einem Impulsgeberring zur Erzeugung der Drehzahl der Antriebswelle entsprechenden Impulsfolge versehen sein. Weitere Vorteile können dadurch erzielt werden, daß die Reibscheibe im Getriebe- oder Lagergehäuse der Antriebswelle axial verschiebbar und durch den Anpreßdruck des Druckteils der Reibkupplung bei Aktivierung der Sicherungsvorrichtung gegen das Gehäuse preßbar sein kann. Hierzu kann die Reibscheibe vorteilhafterweise auf der dem Gehäuse zugewandten Seite ebenfalls einen Reibbelag aufweisen. Durch das Anpressen der Reibscheibe gegen das stabile Gehäuse können sehr hohe Drücke zur Erzeugung eines Bremsmoments aufgenommen werden. Diese Ausgestaltung eignet sich daher insbesondere für Absturzsicherungen für besonders schwere Objekte wie Rolltore. Bei dieser Ausgestaltung kann außerdem zwischen Gehäuse und Reibplatte ein Dichtring sowie Leitbleche zum Abführen von gegebenenfalls durch die Dichtung dringenden Getriebeöl zu dafür vorgesehenen Öffnungen im Gehäuse angeordnet sein. Die Reibscheibe ist somit doppelt, einmal durch die Dichtung und einmal durch die Leitbleche und Abführöffnungen im Gehäuse gegen ungewollte Berührungen mit Getriebeöl, die die Absturzsicherung durch ein Durchdrehen der Reibscheibe wirkungslos machen könnte, geschützt.Instead of the claw clutch proposed so far, there is a friction clutch which exerts a braking torque on the drive shaft for the object that can be moved up and down. In the case of friction clutches, the force absorption when engaging is gentler and therefore more gentle on the material than when a claw clutch is positively locked. To ensure a sufficiently high braking torque, the pressure part is not only displaced electromagnetically with respect to the carrier plate, but is additionally pressed against the friction disc by elements which exert spring force between the housing in which the friction disc is arranged and the carrier plate. The pressure part and the friction disc can each be provided with a friction lining on the mutual contact surfaces, which improve the frictional engagement and protect the material of the friction disc and pressure part. The pressure part is formed by two parallel thrust washers that can be rotated to a limited extent, each of which has ramp-shaped elevations on its mutually facing sides, which slide together due to the relative rotation of the two pressure plates when the pressure part is pressed against the friction disk, and thereby the two pressure plates in the axial direction apart, which increases the force exerted by the elements acting between the housing and the carrier plate and thus the braking torque generated by the friction clutch. As soon as the fall protection is activated and the pressure part comes into contact with the friction disc, the two pressure discs are rotated and the braking torque exerted on the drive shaft is increased. The pressure part of the friction clutch can be displaceable under the influence of at least one electromagnet relative to the carrier plate in the axial direction against the friction disk and in the opposite direction can be pretensioned by at least one spring, the power supply of the at least one electromagnet being controlled by a switching device which provides a pulse comparison stage comprises a first input for a has the first pulse train corresponding to the speed of the drive shaft and a second input for a second pulse train corresponding to the speed of the drive motor and the output signal thereof controls the interruption of the power supply. This switching device for the power supply requires little effort and only minor interventions in an existing drive system, so that a subsequent installation of the safety device presents no difficulties even when using this switching device. The circumference of the friction disk can be provided with a pulse generator ring for generating the pulse sequence corresponding to the speed of the drive shaft. Further advantages can be achieved in that the friction disk in the gearbox or bearing housing of the drive shaft can be axially displaceable and can be pressed against the housing by the contact pressure of the pressure part of the friction clutch when the securing device is activated. For this purpose, the friction disk can advantageously also have a friction lining on the side facing the housing. By pressing the friction disc against the stable housing, very high pressures for generating a braking torque can be absorbed. This configuration is therefore particularly suitable for fall protection for particularly heavy objects such as roller shutters. In this embodiment, a sealing ring and baffles can be arranged between the housing and the friction plate for removing gear oil that may penetrate through the seal to openings provided for this purpose in the housing. The friction disc is thus double, once by the seal and once by the baffles and discharge openings in the housing against unintentional contact with gear oil, which could make the fall protection ineffective by turning the friction disc.

Fig. 1 zeigt eine Antriebswelle 10 eines nicht näher dargestellten Rolltores. In die Antriebswelle 10 ist eine Einsteckwelle 11 eingeführt, auf der eine Reibscheibe 12 drehstarr, aber in axialer Richtung verschiebbar angeordnet ist. Die Reibscheibe 12 bildet zusammen mit einem Druckteil 13 eine Reibkupplung. Sie ist hierzu sowohl auf der den Druckteil 13 als auch auf der dem Gehäuse 16 zugewandten Seite jeweils mit einem Reibbelag 14 versehen. Der Druckteil 13 weist eine Trägerplatte 15 auf, mit der eine Magnetspule 17 fest verbunden ist. Die Magnetspule 17 ist währende des Normalbetriebs des Rolltores bestromt und hält eine Ankerplatte 18 gegen die Feder kraft von Federn 19, die zwischen Trägerplatte 15 und der Ankerplatte 18 angreifen, fest. Mit der Trägerplatte 15 ist außerdem eine erste Druckscheibe 20 mittels Stiften 21 axial verschiebbar aber gegen Verdrehung gesichert verbunden. Die erste Druckplatte 20 wirkt mit einer zweiten Druckplatte 22 zusammen, die auf ihrer Vorderseite mit einem Reibbelag 23 versehen ist, der bei Aktivierung der Sicherheitsvorrichtung gegen den Reibbelag 14 der Reibscheibe 12 zur Anlage kommt. Die Ausgestaltung der Druckplatten 20 und 22 ist in den Fig. 4 bis 7 verdeutlicht. Die Druckplatte 22 weist Anschlagsegmente 24 auf, die ein Verdrehen der Druckplatte 22 gegenüber der Druckplatte 20 begrenzen (Fig. 4). Beide Druckplatten 20 und 22 weisen außerdem rampenförmige Erhebungen 25 bzw. 26, die insbesondere aus den Schnittbildern der Fig. 5 und 7 ersichtlich sind, auf. Die Erhebungen 25 und 26 sind dabei so geformt, daß die beiden Druckplatten 20 und 22 im Normalbetrieb des Rolltores formschlüssig aneinanderliegen und in dieser Lage durch Druckfedern 27 gehalten werden, wie in Fig. 1 gezeigt ist. In diesem Zustand ist zwischen der Reibscheibe 12 und der Druckplatte 22 ein Luftspalt a vorhanden, so daß sich die Reibscheibe 12 , die Einsteckwelle 11 und die Antriebswelle 10 frei drehen können. Die Trägerplatte 15, die wie in Fig. 2 gezeigt ist, durch Hülsen 28 und Schrauben 29 verdrehsicher aber axial verschiebbar mit dem Gehäuse 16 verbunden ist, liegt dabei direkt am Gehäuse 16 an.Fig. 1 shows a drive shaft 10 of a roller shutter, not shown. An insertion shaft 11 is introduced into the drive shaft 10, on which a friction disk 12 is arranged so as to be non-rotatable but displaceable in the axial direction. The friction disk 12 forms a friction clutch together with a pressure part 13. For this purpose, it is provided with a friction lining 14 both on the pressure part 13 and on the side facing the housing 16. The pressure part 13 has a carrier plate 15, to which a magnet coil 17 is firmly connected. The solenoid 17 is energized during normal operation of the roller shutter and holds an anchor plate 18 against the spring force of springs 19 which engage between the support plate 15 and the anchor plate 18. A first thrust washer 20 is also connected axially displaceably to the carrier plate 15 by means of pins 21 but secured against rotation. The first pressure plate 20 interacts with a second pressure plate 22, which is provided on its front side with a friction lining 23, which comes into contact with the friction lining 14 of the friction disk 12 when the safety device is activated. The design of the pressure plates 20 and 22 is illustrated in FIGS. 4 to 7. The pressure plate 22 has stop segments 24 which limit rotation of the pressure plate 22 relative to the pressure plate 20 (FIG. 4). Both pressure plates 20 and 22 also have ramp-shaped elevations 25 and 26, which can be seen in particular from the sectional images of FIGS. 5 and 7. The elevations 25 and 26 are shaped in such a way that the two pressure plates 20 and 22 lie against one another in a form-fitting manner during normal operation of the roller shutter and are held in this position by compression springs 27, as shown in FIG. 1. In this state, an air gap a is present between the friction disk 12 and the pressure plate 22, so that the friction disk 12, the insert shaft 11 and the drive shaft 10 can rotate freely. The carrier plate 15, which, as shown in FIG. 2, is connected to the housing 16 in such a way that it can be rotated but is axially displaceable by sleeves 28 and screws 29, lies directly against the housing 16.

Zur Überwachung des Betriebszustandes des Rolltores sind jeweils eine Impulsgebereinrichtung am Motor und am Getriebe vorgesehen. Die von diesen Einrichtungen erzeugten Impulsfolgen werden von einer Impulsvergleichsstufe ständig überwacht. Tritt eine Abweichung des Differenzsignals von einem Sollwert auf, so wird die Stromversorgung der Magnetspule 17 unterbrochen und dadurch die Absturzsicherung aktiviert. Von den Impulsgebereinrichtungen sind in Fig. 1 ein Näherungsschalter 30 und ein am Umfang der Reibscheibe 12 angeordneter Impulsgeberring 31 , der die der Drehzahl der Antriebswelle 10 entsprechende Impulsfolge erzeugt, dargestellt.To monitor the operating state of the roller shutter, a pulse generator is provided on the motor and on the gearbox. The pulse trains generated by these devices are constantly monitored by a pulse comparison stage. If there is a deviation of the difference signal from a desired value, the power supply to the magnetic coil 17 is interrupted and the fall protection is thereby activated. 1, a proximity switch 30 and a pulse generator ring 31 arranged on the circumference of the friction disk 12, which generates the pulse sequence corresponding to the speed of the drive shaft 10, are shown in FIG. 1.

Die Funktion der Sicherungsvorrichtung stellt sich nun wie folgt dar: Bei einem Bruch oder anderweitigem Versagen von Bauteilen des Antriebssystems des Rolltores erkennt eine Überwachungseinheit eine Ungleichheit in den vom Motor und vom Getriebe herrührenden Impulsfolgen und unterbricht die Stromversorgung der Magnetspule 17, d.h. die Ankerplatte 18 wird nicht mehr festgehalten sondern von den Federn 19 mit den Druckplatten 20 und 22 gegen die Reibscheibe 12 bewegt. Der Luftspalt a schließt sich, und die Reibscheibe 12 erzeugt sowohl am Gehäuse 16 als auch an der Druckplatte 22 ein Reibmoment. Dieses Reibmoment führt zu einer Verdrehung der Druckplatte 22 gegenüber der Druckplatte 20, da die Reibung zwischen den beiden Belägen 14 und 23 von Reibscheibe 12 und Druckplatte 22 größer ist als die Reibung zwischen den beiden Druckplatten 22 und 20. Die Verdrehbewegung der Platten 20 und 22 führt zu einem Entlanggleiten der schiefen Ebenen 25.1 und 26.1 der rampenförmigen Erhebungen 25 und 26, bis die Anschlagsegmente 24 der Druckplatte 22 gegen das Gehäuse 16 in Anschlag kommen und eine weitere Drehbewegung verhindern. Das gegenseitige Entlanggleiten der rampenförmigen Erhebungen 25 und 26 führt zu einem fortgesetzten axialen Auseinanderpressen der beiden Druckplatten 20 und 22, bis die Druckplatte 22 mit ihren Anschlagsegmenten 24 am Gehäuse 16 anliegt. Durch die Axialbewegung wird die Druckplatte 20 gegen die Trägerplatte 15 gepreßt, wodurch zwischen der Trägerplatte 15 und dem Gehäuse 16 ein Spalt entsteht und dort angeordnete Federpakete 32 komprimiert werden und ein zusätzliches Bremsmoment erzeugen, welches die Antriebswelle 10 des Rolltores verzögert und stillsetzt.The function of the safety device is now as follows: In the event of a breakage or other failure of components of the drive system of the roller shutter, a monitoring unit detects an inequality in the pulse sequences originating from the motor and the transmission and interrupts the power supply to the solenoid 17, ie the armature plate 18 no longer held but moved by the springs 19 with the pressure plates 20 and 22 against the friction disk 12. The air gap a closes and the friction disc 12 creates both on the housing 16 and on the pressure plate 22 Friction torque. This frictional torque leads to a rotation of the pressure plate 22 with respect to the pressure plate 20, since the friction between the two linings 14 and 23 of the friction disk 12 and the pressure plate 22 is greater than the friction between the two pressure plates 22 and 20. The rotation of the plates 20 and 22 leads to the inclined planes 25.1 and 26.1 of the ramp-shaped elevations 25 and 26 sliding along until the stop segments 24 of the pressure plate 22 come into abutment against the housing 16 and prevent a further rotational movement. The mutual sliding along of the ramp-shaped elevations 25 and 26 leads to a continued axial pressing of the two pressure plates 20 and 22 until the pressure plate 22 abuts the housing 16 with its stop segments 24. Due to the axial movement, the pressure plate 20 is pressed against the carrier plate 15, as a result of which a gap is formed between the carrier plate 15 and the housing 16 and spring assemblies 32 arranged there are compressed and generate an additional braking torque which decelerates and stops the drive shaft 10 of the roller shutter.

Fig. 3 zeigt in einer Detailansicht eine Abdichtung zwischen dem Getriebe der Antriebswelle 10 und der Reibscheibe 12. Es ist ein Dichtring 33 vorgesehen, der ein Eindringen von Getriebeöl in den Gehäusebereich, in dem die Reibscheibe 12 angeordnet ist, verhindern soll. Für den Fall, daß der Dichtring seine Dichtwirkung verliert, sind vor dem Dichtring 33 Führungsbleche 34 vorgesehen, die eventuell eindringendes Öl in Richtung auf Auslaßkanäle 35 im Gehäuse 16 leiten und damit verhindern, daß Getriebeöl auf die Reibscheibe gelangen und deren Funktion zur Erzeugung eines Bremsmoments auf die Antriebswelle des Rolltores unwirksam machen kann.3 shows a detailed view of a seal between the gearbox of the drive shaft 10 and the friction disk 12. A sealing ring 33 is provided which is intended to prevent gear oil from penetrating into the housing area in which the friction disk 12 is arranged. In the event that the sealing ring loses its sealing effect, 33 guide plates 34 are provided in front of the sealing ring, which guide any oil that may penetrate in the direction of outlet channels 35 in the housing 16 and thus prevent gear oil from getting onto the friction disk and their function to generate a braking torque on the drive shaft of the roller shutter.
