Abstract

The escalator or moving pavement has a cleaning device (10) which is engaged at least partially during the transporting and maintenance operation of the escalator or moving pavement, and has a control element through which a brush bearing (14) is movable. The control element is connected to the brush bearing by a lever (16) or other gear. The control element bears against the top surface of the tread area (48) to be cleaned and especially with spring-loading. An Independent claim is included for a cleaning device for the cleaning of an escalator or moving pavement and equipped with revolving brushes which rotate during the transporting operation of the escalator or moving pavement.

Description

Die Erfindung betrifft eine Fahrtreppe oder einen Fahrsteig, gemäß dem Oberbegriff von Anspruch 1 und ein Verfahren gemäß dem Oberbegriff von Anspruch 11.The invention relates to an escalator or moving walk, according to the preamble of claim 1 and a method according to the preamble of claim 11.

Derartige Fahrtreppen oder Fahrsteige mit Reinigungsvorrichtungen sind seit langem bekannt. Beispielsweise ist bereits in der JP-A-02/58595 oder DE-OS 30 16 597 eine Vorrichtung zum Reinigen einer Fahrtreppe beschrieben.Such escalators or moving walks with cleaning devices have long been known. For example, is already in the JP-A-02/58595 or DE-OS 30 16 597 a device for cleaning an escalator described.

Eine gattungsgemäße Fahrtreppe oder ein entsprechender Fahrsteig ist aus der DE-OS 37 04 388 bekannt. Bei dieser Lösung ist eine umlaufende Bürste vorgesehen, die an einem Bürstenlager gelagert ist und eine Stufe oder Palette der Fahrtreppe oder des Fahrsteigs reinigen soll. Die in dieser Druckschrift beschriebene Lösung soll insbesondere den Bereich der Vertikalflächen der Stufen reinigen, wobei die Reinigung zusätzlich durch eine Absaughaube unterstützt werden soll. Die rotierende Büstenwalze wird bei stehender Fahrtreppe über die einzelnen Stufen mit Ihrer Trittflächen und Setzstufen geführt, so dass nach und nach das Stufenband gereinigt werden kann.A generic escalator or a corresponding moving walkway is from the DE-OS 37 04 388 known. In this solution, a rotating brush is provided, which is mounted on a brush bearing and should clean a step or pallet of the escalator or moving walk. The solution described in this document is intended in particular to clean the area of the vertical surfaces of the steps, wherein the cleaning is additionally to be supported by a suction hood. The rotating brush roller is guided with the steps and risers on the individual steps with the escalator standing, so that gradually the step belt can be cleaned.

Ausweislich der Beschreibung soll bevorzugt bei der untersten Trittfläche, also der unteren Kammplatte benachbart begonnen werden. Wenn die obere Kammplatte erreicht ist, muss die Fahrtreppe wohl zur Weiterreinigung erneut eingeschaltet werden, und bei jeder Fahrtreppe muss diese mühsame halb automatische und halb manuelle Reinigung je dreimal wiederholt werden, um das Stufenband vollstänig zu reinigen.Evidence of the description should be preferred in the lowest Tread, so the lower comb plate to be started adjacent. When the top comb plate is reached, the escalator may need to be turned on again for further cleaning, and at each escalator, this tedious semi-automatic and semi-manual cleaning must be repeated three times to completely clean the step band.

Dennoch ist nicht sichergestellt, dass die mit der Reinigung beauftragte Person nicht Bereiche des Stufenbandes übersieht, so dass eine gewisse Sorgfalt bei der Bedienung von nöten ist.However, there is no guarantee that the person responsible for the cleaning will not overlook areas of the step belt, so that a certain amount of care in the operation is necessary.

Es sind mittlerweile zahlreiche weitere Vorschläge für Fahrtreppen- oder Fahrsteigreinigungsgeräte bekannt geworden. Ein Beispiel ist hierfür der EP-A2-191 888 zu entnehmen. Bei dieser Lösung wird die Bewegung der Fahrtreppe ausgenutzt, wobei der Kammplatte benachbart ein Rahmen zu Reinigungszwecken der Fahrtreppe quer über die Breite der Fahrtreppe zwischen den Balustraden gespannt wird, und wobei ein Schlitten Reinigungsbürsten über die Stufenbreite verfährt. Diese Lösung hat den Vorteil, dass der Bedienungsaufwand geringer ist. Nachteilig ist, dass es prinzipbedingt ausgeschlossen ist, dass Setzstufen gereinigt werden.There are now numerous other proposals for escalator or moving staircase cleaning devices become known. An example of this is the EP-A2-191888 refer to. In this solution, the movement of the escalator is exploited, wherein the comb plate adjacent a frame is stretched across the width of the escalator between the balustrades for cleaning purposes of the escalator, and wherein a carriage cleaning brushes moves across the step width. This solution has the advantage that the operating costs are lower. The disadvantage is that it is excluded by principle that risers are cleaned.

Andererseits sind Setzstufen meist recht verschmutzungsempfindlich. Während die Finger der Kammplatte regelmäßig in die Nuten der Trittstufe eingreifen und eine partielle Reinigung ermöglichen, sind derartige Maßnahmen bei Setzstufen regelmäßig nicht vorgesehen. Zu starke Verschmutzungen können aber die Relativbewegung benachbarter Stufen beeinträchtigen und zu Störfällen führen.On the other hand risers are usually very susceptible to contamination. While the fingers of the comb plate regularly engage in the grooves of the tread and allow partial cleaning, such measures are regularly not provided at risers. However, excessive contamination can impair the relative movement of adjacent stages and lead to incidents.

Bei Fahrtreppenstufen ist der Übergangsbereich zwischen Trittstufe und Setzstufen, also die Vorderkante der Fahrtreppe besonders empfindlich. Dort gehen die Stege der Setzstufe in die der Trittstufe über. In diesem Bereich sind die Stege lediglich von unten abgestützt und seitlich relativ ungeschützt.For escalator steps, the transitional area between tread and risers, ie the leading edge of the escalator, is particularly sensitive. There, the webs of the riser go over into the step. In this area, the webs are supported only from below and laterally relatively unprotected.

Andererseits geraten diese Bereiche beim betreffenden Betrieb als erstes in Eingriff mit den Kammplatten, die es erfordern, dass jede Nut seitlich des betreffenden Steges frei ist. Dort vorhandene Verunreinigungen - wie beispielsweise eingetrockene Kaugummireste - können zum Bruch der Zähne der Kammplatte führen oder aber die Spitze des Steges beim Eingriff der Kammplatte beschädigen.On the other hand, these areas are the first to engage in the operation concerned with the comb plates, which require that each groove is free laterally of the respective web. There existing impurities - such as dry gum residues - can lead to breakage of the teeth of the comb plate or damage the tip of the web during engagement of the comb plate.

Um die Schadensneigung bei der Kammbewegung zwischen Trittstufe und Kammplatte zu reduzieren, ist es auch bekannt geworden, durch innenliegende, in der Kammplatte angebrachte Düsen die Verunreinigungen aufzuweichen, was den Vorteil hat, dass die Kammplatte ihre Grobreinigungsfunktion - zumindest bei bestimmten Verunreinigungssubstanzen - besser wahrnehmen kann. Derartige Lösungen sind jedoch nicht geeignet, wenn wasserunlösliche Verunreinigungen, wie beispielsweise die angesprochenen Kaugummireste, entfernt werden müssen. Zudem führt die Beaufschlagung der Fahrtreppe mit einer wässrigen Reinigungsflüssigkeit dazu, dass die Oberfläche der Trittstufen ausgesprochen glatt wird und während des Betriebs der Sprühdüsen nicht betrieben werden sollte.In order to reduce the damage tendency in the comb movement between tread and comb plate, it has also become known to soften by internal, mounted in the comb plate nozzles impurities, which has the advantage that the comb plate their coarse cleaning function - at least for certain contaminants - better perceive , However, such solutions are not suitable if water-insoluble impurities, such as the mentioned chewing gum residues, must be removed. In addition, the application of an aqueous cleaning fluid to the escalator causes the surface of the treads to become extremely smooth and should not be operated during the operation of the spray nozzles.

Ein weiterer Nachteil der Walzenbürsten oder sonstigen umlaufenden Reinigungsbürsten der bislang vorgeschlagenen Reinigungsvorrichtungen für Fahrtreppen besteht darin, dass die Walzenbüste zwar zur Reinigung der Trittfläche in der Lage ist, jedoch gerade die wichtige Vorderkante - und auch die Hinterkante - der Trittstufe meist eher schlecht reinigt. Der Übergangsbereich der Setzstufe wird überhaupt nicht gereinigt.Another disadvantage of the roller brushes or other circulating cleaning brushes of the previously proposed cleaning devices for escalators is that the roller bust is indeed able to clean the tread, but just the important leading edge - and the trailing edge - the tread usually cleans rather poorly. The transition area of the riser is not cleaned at all.

Daher liegt der Erfindung die Aufgabe zugrunde, eine verbesserte Reinigung von Fahrtreppen oder Fahrsteigen bereitzustellen, die die Wartungskosten der Fahrtreppe und des Fahrsteiges deutlich reduziert, ohne dass besonders hohe Investitionen erforderlich wären.It is therefore an object of the invention to provide an improved cleaning of escalators or moving walkways, which significantly reduces the maintenance costs of the escalator and the moving walk, without requiring particularly high investments.

Diese Aufgabe wird erfindungsgemäß durch Anspruch 1 und Anspruch 11 gelöst. Vorteilhafte Weiterbildungen ergeben sich aus den Unteransprüchen.This object is achieved by claim 1 and claim 11. Advantageous developments emerge from the subclaims.

Überraschend ermöglicht die erfindungsgemäße Fahrtreppe erstmals die Reinigung einer Fahrtreppe oder Fahrsteigs während des Betriebs der Fahrtreppe, also nicht nur, während die Fahrtreppe oder der Fahrsteig umläuft, sondern, während die Fahrtreppe oder der Fahrsteig Fahrgäste transportiert.Surprisingly, the escalator according to the invention allows for the first time the cleaning of an escalator or moving walkway during operation of the escalator, so not only while the escalator or moving walkway rotates but, while the escalator or moving walkway transports passengers.

Erfindungsgemäß ist es hier besonders günstig, wenn die Reinigungsvorrichtung unterhalb des oberen Trumes des Stufen- oder Palettenbandes wirkt, beispielsweise im Umlenkbereich oder im Bereich des unteren Trumes des Stufen- oder Palettenbandes. Durch das erfindungsgemäße Steuerelement lässt sich der Abstand zwischen der Reinigungsoberfläche und der umlaufenden Bürste steuern. Hierdurch ist sichergestellt, dass die umlaufende Bürste über die Fläche der Trittstufe eine intensive Reinigung vornimmt, aber im Bereich der Vorder- oder Hinterkante keine zu hohe Flächenpressung erzeugt. Wenn die Bürste rein federbelastet an die zu reinigende Oberfläche gedrückt würde, wäre der Reinigungsdruck im Bereich der Vorderkante und der Hinterkante der Trittstufe derart hoch, dass dort Verschleißerscheinungen auftreten würden und insbesondere die Borsten der umlaufenden Bürste durch die dort bestehenden Spitzen leicht beschädigt werden könnten.According to the invention, it is particularly advantageous here if the cleaning device acts below the upper step of the step or pallet strip, for example in the deflection region or in the region of the lower part of the step or pallet strip. By controlling the invention, the distance between the cleaning surface and the rotating brush can be controlled. This ensures that the rotating brush performs an intensive cleaning over the surface of the tread, but does not generate too high surface pressure in the region of the leading or trailing edge. If the brush was pressed purely spring loaded on the surface to be cleaned, the cleaning pressure in the region of the leading edge and the rear edge of the tread would be so high that there would be signs of wear and in particular the bristles of the rotating brush could be easily damaged by the existing there tips.

Erfindungsgemäß ist es demgegenüber besonders günstig, wenn ein Steuerelement den Abstand zwischen der zu reinigenden Oberfläche und der Bürste konstant hält, so dass die Treppenstufen-Hinterkante und -Vorderkante sanft aber gründlich gereinigt werden kann.In contrast, according to the invention, it is particularly advantageous if a control keeps the distance between the surface to be cleaned and the brush constant, so that the staircase leading edge and leading edge can be gently but thoroughly cleaned.

Erfindungsgemäß besonders günstig ist es, dass sich das Stufen- oder Palettenband im Umlenkbereich automatisch aufspreizt. Dadurch ist es sichergestellt, dass die Bürste besonders gut die Kanten der Trittstufe erfassen kann. Bei Bedarf ist es auch möglich, zusätzlich die Setzstufen zu reinigen, wobei es sich versteht, dass hierfür eine schnelle - gegebenenfalls motorisch unterstützte - Bewegung des Bürstenlagers möglich sein sollte, um ein rasches Eindringen und Austreten der Bürste in den Spalt zwischen zwei Stufen zu ermöglichen, während das Stufen- oder Palettenband umläuft.According to the invention, it is particularly favorable that the step or pallet strip spreads automatically in the deflection region. This ensures that the brush is extra good at grasping the edges of the step. If necessary, it is also possible to additionally clean the risers, it being understood that this rapid - possibly motor assisted - movement of the brush bearing should be possible to allow rapid penetration and exit of the brush in the gap between two stages while the tier or pallet band is revolving.

Erfindungsgemäß besonders günstig ist es, wenn als Steuerelemente Steuerscheiben vorgesehen sind, die seitlich des Stufenoder Palettenbandes angeordnet sind und eine oberflächentreue Führung der umlaufenden Bürste ermöglichen.According to the invention, it is particularly advantageous if control disks are provided as controls, which are arranged laterally of the step or pallet belt and allow a surface-true guidance of the rotating brush.

Durch die co-axiale, getriebefreie Lagerung lassen sich die umzusteuernden Massen gering halten, so dass die umlaufende Bürste verschleißarm an den zu reinigenden Oberflächen anliegt, wobei sichergestellt ist, dass die Walzenbürste den Bewegungen der Steuerscheibe rasch folgen kann.Due to the coaxial, transmission-free storage, the materials to be reversed can be kept low, so that the rotating brush rests wear-resistant on the surfaces to be cleaned, it being ensured that the roller brush can follow the movements of the control disk quickly.

Erstmals bietet die erfindungsgemäße Lösung die Möglichkeit, die Fahrtreppe oder den Fahrsteig auch während des Förderbetriebs zu reinigen. Hierzu ist die Reinigungsvorrichtung jedenfalls unterhalb des oberen Trumes des Stufen- oder Palettenbandes untergebracht. Besonders geeignet ist eine der Umkehrstellen, insbesonderes die untere Umkehrstelle, oder jedenfalls diejenige, an welcher der Antriebsmotor für das Stufen- oder Palettenband nicht vorgesehen ist. Im Bereich der Umkehrstelle spreizt sich das Stufen- oder Palettenband auf, so dass die Reinigungsmöglichkeit besonders gut oder intensiv gegebenen ist und die Walzenbürste dem sich ihr darbietenden Reinigungsprofil gut folgen kann.For the first time, the solution according to the invention offers the possibility of cleaning the escalator or moving walk even during the conveying operation. For this purpose, the cleaning device is housed in any case below the upper Trumes the stage or pallet band. Particularly suitable is one of the reversal points, in particular the lower reversal point, or at least that to which the drive motor for the step or pallet band is not provided. In the area of the reversal point, the step or pallet strip spreads so that the possibility of cleaning is given particularly well or intensively and the roller brush can follow the cleaning profile presented to her well.

Erfindungsgemäß besonders günstig ist es, dass die Abstandsführung der Walzenbürste zwar mit einer Andruckfeder ausgestattet sein kann, die Einstellung des Abstandes jedoch über die Steuerscheibe erfolgt. Hierdurch ist gewährleistet, dass die Bürste nicht an den Kanten zu stark und über die Fläche zu wenig anliegt und damit ungleiche Reinigungs- und Abnutzungswirkungen entstehen. Die Andrucksfeder drückt also die Walzenbürste nicht unkontrolliert an die Reinigungsfläche an, sondern gezielt gesteuert über die Steuerscheibe.According to the invention, it is particularly favorable that the distance guide of the roller brush can indeed be equipped with a pressure spring, but the adjustment of the distance is made via the control disk. This ensures that that the brush is not too strong at the edges and too little over the surface and thus uneven cleaning and wear effects. The Andrucksfeder so presses the roller brush not uncontrollably to the cleaning surface, but selectively controlled by the control disk.

Wenn ein möglichst geringes Dreh-Trägheitsmoment erwünscht ist, kann die Antriebswelle für Steuerscheibe und Walzenbürste von einem Ketten- oder Riemengetriebe angetrieben sein, das von einem ortsfesten Antriebsmotor betätigt ist. Bei dieser Lösung ist dann eine Riemenscheibe bevorzugt in der Schwenkachse der Bürstenlagerung angeordnet.If the lowest possible moment of inertia of rotation is desired, the drive disc for the control disc and roller brush can be driven by a chain or belt drive, which is actuated by a stationary drive motor. In this solution, a pulley is then preferably arranged in the pivot axis of the brush bearing.

In einer modifizierten Ausgestaltung ist der Antriebsmotor an die Bürstenlagerung angeflanscht, so dass er mitverschwenkt wird. Die Lösung hat den Vorteil, dass keine Antriebskräfte in die Bürstenlagerung eingebracht werden, so dass die Steuerscheibe weniger belastet wird.In a modified embodiment, the drive motor is flanged to the brush mounting, so that it is mitverschwenkt. The solution has the advantage that no driving forces are introduced into the brush holder, so that the control disk is less stressed.

In einer besonders bevorzugten Ausgestaltung ist der Antriebsmotor für die Walzenbürste in der Bürste selbst integriert. Die Bürste ist bevorzugt auf einem hohlen Zylinder ausgebildet, in dessen Inneren ausreichend Platz für einen in entsprechender Weise geformten Elektromotor vorgesehen ist. Diese Lösung hat auch den Vorteil, dass die Montage und gegebenfalls auch die Wartung deutlich erleichtert ist und damit auch die Wartungskosten reduziert sind.In a particularly preferred embodiment, the drive motor for the roller brush is integrated in the brush itself. The brush is preferably formed on a hollow cylinder, in the interior of which sufficient space is provided for a correspondingly shaped electric motor. This solution also has the advantage that the assembly and, if necessary, the maintenance is much easier and thus the maintenance costs are reduced.

Bevorzugt ist die Steuerscheibe so ausgebildet, so dass sie mit dem umlaufenden Stufen- oder Palettenband, also der je zu reinigenden Oberfläche, umläuft und von diesen mitgenommen wird. Um die für die Reinigungswirkung erwünschte Relativgeschwindigkeit zwischen der Walzenbürste und der zu reinigenden Oberfläche ohne Verschleiß der Steuerscheibe zu ermöglichen, ist es bevorzugt, die Steuerscheibe auf der Welle der Walzenbürste über ein Gleit- oder ein Wälzlager zu lagern.Preferably, the control disk is designed so that it rotates with the revolving step or pallet band, so the surface to be cleaned, and is taken away by them. In order to allow the desired relative to the cleaning effect relative speed between the roller brush and the surface to be cleaned without wear of the control disc, it is preferred to store the control disc on the shaft of the roller brush via a sliding or rolling bearings.

Bevorzugt ist die Bürstenlagerung beidseitig des umlaufenden Stufen- oder Palettenbandes vorgesehen, wobei bei Bedarf ein oder zwei Steuerscheiben vorgesehen sind. Bei der Ausgestaltung mit zwei Steuerscheiben ist eine Verbindung der beiden Bürstenlagerungen nicht erforderlich, während bei der Verwendung einer Steuerscheibe eine verbindungssteife Verbindung beider Bürstenlagerungen erwünscht ist.Preferably, the brush holder is provided on both sides of the revolving step or pallet band, with one or two control discs are provided if necessary. In the embodiment with two control discs, a connection of the two brush bearings is not required, while the use of a control disc a connection-rigid connection of both brush bearings is desired.

Das Steuerelement kann auch in beliebiger anderer Ausgestaltung ausgebildet sein. Beispielsweise kann ein mit einer Anlagerolle versehener Hebel den Abstand zwischen der zu reinigenden Oberfläche und der Walzenbürste einstellen, bei Bedarf über einen Hebel oder ein sonstiges Getriebe.The control can also be designed in any other configuration. For example, a lever provided with a locating roller can adjust the distance between the surface to be cleaned and the roller brush, if necessary via a lever or other gear.

Bevorzugt wird die Reinigungsvorrichtung periodisch während des Förderbetriebs eingeschaltet. Durch diese Lösung lässt sich eine gute Reinigung mit einem geringen Verschleiß der Walzenbürste kombinieren. Hierzu ist dann bevorzugt, ein Zugmagnet vorgesehen, der gegen die Wirkung der Andruckfeder die Walzenbürsten von der zu reinigenden Oberfläche abhebt, während die Reinigungsvorrichtung nicht arbeitet. Während des Reinigungsbetriebs wird der Elektromagnet freigegeben. Eine vorteilhaften Ausgestaltung dieser Lösung weist zwei Elektomagnete auf und arbeitet mit einer Rastvorrichtung, die die Reinigungsvorrichtung in Ruhestellung einrasten lässt, wenn der Zugmagnet die Walzenbürste von der zu reinigenden Oberfläche abgehoben hat. Für den Reinigungsbetrieb muss dann lediglich kurz ein weiterer Elekromagnet betätigt werden, der das Rastelement zurückzieht und damit die Walzenbürste der Wirkung der Andruckfeder aussetzt.Preferably, the cleaning device is switched on periodically during the conveying operation. This solution combines good cleaning with low wear of the roller brush. For this purpose, it is preferred, a pull magnet is provided which lifts against the action of the pressure spring roller brushes of the surface to be cleaned, while the cleaning device is not working. During the cleaning operation, the solenoid is released. An advantageous embodiment of this solution has two Elektomagnete and works with a locking device that can engage the cleaning device in the rest position when the pull magnet has lifted the roller brush from the surface to be cleaned. For the cleaning operation then only a short Elekromagnet must be actuated, which retracts the locking element and thus exposing the roller brush the action of the pressure spring.

Die in Fig. 1 dargestellte Reinigungsvorrichtung 10 weist eine bevorzugt als Walzenbürste 12 ausgebildete umlaufende Bürste auf, die über ein Bürstenlager 14 drehbar an einem Schwenkhebel 16 einer Bürstenlagerung 18 gelagert ist. Der Schwenkhebel 16 ist seinerseits an seiner Schwenkachse 20 an einem rahmenfesten Träger 22 der Fahrtreppe oder des Fahrsteigs gelagert. Der Träger 22 ist im Bereich der unteren Umkehrstelle 24 des Stufen- oder Palettenbands vorgesehen. In dem dargestellten Ausführungsbeispiel sind drei Stufen 26, 28 und 30 einer Fahrtreppe beispielhaft dargestellt. Im Bereich der Umkehrstelle 24 spreizen sich die Stufen je auf, so dass ihre Vorderkante 32 und ihre Hinterkante 34 je frei liegen. Auch der obere Teil der Setzstufe 36 ist exponiert und kann erfindungsgemäß von der Walzenbürste mit gereinigt werden.In the Fig. 1 cleaning device 10 shown has a preferably designed as a roller brush 12 circumferential brush, which is rotatably supported via a brush bearing 14 on a pivot lever 16 of a brush holder 18. The pivot lever 16 is in turn mounted on its pivot axis 20 on a frame-fixed support 22 of the escalator or moving walk. The carrier 22 is provided in the region of the lower reversal point 24 of the step or pallet band. In the illustrated embodiment, three stages 26, 28 and 30 of an escalator are exemplified. In the area of the reversal point 24, the steps each spread apart so that their leading edge 32 and their trailing edge 34 are each exposed. Also, the upper part of the riser 36 is exposed and can be cleaned according to the invention of the roller brush with.

Erfindungsgemäß ist auf der aus Fig. 2 besser ersichtlichen Welle 40 der Walzenbürste 12 ein Steuerelement, bevorzugt in Form einer Steuerscheibe 42, gelagert. Die Lagerung erfolgt in dem dargestellten Ausführungsbeispiel über ein Wälzlager, hier ein Kugellager 44, wobei es sich versteht, dass beliebige andere Lager ebenfalls möglich sind. Wie ersichtlich ist, weisen die Bürsten der Walzenbürste 12 ein Vorsprungmaß 46 gegenüber dem Durchmesser der Steuerscheibe 42 auf. Mit der Wahl des Vorsprungmaßes, also praktisch der Wahl des Durchmessers der Steuerscheibe 42, lässt sich die Reinigungswirkung der Walzenbürste an die Erfordernisse anpassen. Je größer das Vorsprungmaß 46 ist, desto intensiver ist die Reinigung, aber zugleich auch der Verschleiß sowohl der Oberfläche der Trittflächen 48, der Vorderkante 32 und der Hinterkante 34, als auch der Borsten der Walzenbürste 12 selbst.According to the invention is based on Fig. 2 better visible shaft 40 of the roller brush 12, a control, preferably in the form of a control disk 42, stored. The storage takes place in the illustrated embodiment via a rolling bearing, here a ball bearing 44, it being understood that any other bearings are also possible. As can be seen, the brushes of the roller brush 12 have a projection dimension 46 relative to the diameter of the control disk 42. With the choice of the projection dimension, so practically the choice of the diameter of the control disk 42, the cleaning effect of the roller brush can be adapted to the requirements. The larger the projection 46, the more intense the cleaning, but at the same time the wear of both the surface of the treads 48, the leading edge 32 and the trailing edge 34, as well as the bristles of the roller brush 12 itself.

Wie aus Fig. 2 ebenfalls ersichtlich ist, ist die Welle 40 über ein Umlenkgetriebe 50 mit einem Antriebsmotor 52 verbunden. In dem dargestellten Ausführungsbeispiel ist der Antriebsmotor 52 direkt an die Bürstenlagerung 18 angeflanscht, und zwar möglichst nahe an der Schwenkachse 20.How out Fig. 2 is also apparent, the shaft 40 is connected via a deflection gear 50 with a drive motor 52. In the illustrated embodiment, the drive motor 52 is flanged directly to the brush support 18, and as close as possible to the pivot axis 20th

Bevorzugt ist die Walzenbürste mit einer Borstenreihe versehen, die sich leicht spiralig gewendelt über den axialen Verlauf der Bürste erstreckt und bei der jede Borstenreihe an einem Bürstensegment gelagert ist. Diese Lösung erlaubt ein Austauschen der Borsten je nach Verschleiß und Bedarf mit geringem Aufwand. Erfindungsgemäß besonders günstig ist es, dass mit recht geringen Bürstendrehzahlen gearbeitet werden kann, so dass der Verschleiß trotz intensiver Reinigung gering ist. Beispielsweise ist ein Antrieb der Walzenbürste mit einer Geschwindigkeit von weniger als einer Umdrehung pro Sekunde möglich; die Reinigungsrichtung ist bevorzugt gegen die Laufrichtung der Fahrtreppe gewählt.Preferably, the roller brush is provided with a row of bristles, which extends slightly spirally wound over the axial course of the brush and in which each row of bristles is mounted on a brush segment. This solution allows replacement of bristles depending on wear and need with little effort. It is particularly favorable according to the invention that it is possible to work with fairly low brush speeds, so that the wear is low despite intensive cleaning. For example, a drive of the roller brush at a speed of less than one revolution per second is possible; the cleaning direction is preferably selected against the running direction of the escalator.

Bei Fahrtreppen mit Richtungsumkehr ist es bevorzugt, die Antriebsgeschwindigkeit der Walzenbürst je nach Fahrtrichtung der Fahrtreppe umzukehren, wobei sich versteht, dass auch der Reinigungszyklus lediglich dann freigeschaltet werden kann, wenn die Fahrtreppe in der gewünschten Fahrtrichtung läuft.For escalators with direction reversal, it is preferable to reverse the drive speed of the roller brush depending on the direction of travel of the escalator, it being understood that the cleaning cycle can only be unlocked when the escalator is running in the desired direction.
