Abstract

An apparatus for cleaning escalator steps having grooved front surfaces cleans during the operation of the escalator. A brush extending across the entire width of each step is positioned under the rear edge of the tread. The bristles of the brush press against the front surface of the adjacent step when the steps are in predetermined regions of the escalator. The relative motion of the steps as they move from the horizontal to the inclined and back to the horizontal regions creates a relative vertical motion between the brush and the front surface for the cleaning of the front surface. The front surface thus is cleaned twice per revolution of the step conveyor by being moved against the brush bristles, once from top to bottom and once from bottom to top, practically across the entire height of the step.

Description

Die Erfindung betrifft eine Reinigungseinrichtung für die Stufen einer Fahrtreppe, mit mindestens einer über die ganze Breite einer Stufe ragenden Bürste.The invention relates to a cleaning device for the steps of an escalator, with at least one brush projecting over the entire width of a step.

Die Reinigung der Fahrtreppen, vor allem der Trittflächen und der Stirnflächen der Stufen, welche beide Rippen und Rillen aufweisen, wird vor allem dann aufwendig, wenn trotz grossem Schmutzanfall nur in grossen Zeitabständen Reinigungen durchgeführt werden. Ein Teil des Schmutzes, der sich auf den Stufen ablagert, wird wohl vor allem bei trockenem Wetter je nach der Laufrichtung der Fahrtreppe in der oberen oder in der unteren Umlenkstation in eine Schmutzwanne automatisch abgekippt. Ein Teil des Schmutzes kann sich aber in den Rillen festsetzen und lässt sich daraus nur schwer entfernen. Aus diesem Grunde sind bereits verschiedene Einrichtungen zum Reinigen von Fahrtreppen, insbesondere von Stufen von Fahrtreppen konstruiert und mit mehr oder weniger Erfolg praktisch eingesetzt worden.The cleaning of the escalators, especially the treads and the end faces of the steps, which both have ribs and grooves, is particularly complex if, despite the large amount of dirt, cleaning is only carried out at large intervals. Part of the dirt that is deposited on the steps is probably tipped into a dirt trough in the upper or lower deflection station, especially in dry weather, depending on the direction in which the escalator is running. Part of the dirt can get stuck in the grooves and is difficult to remove. For this reason, various devices for cleaning escalators, in particular escalator steps, have already been constructed and have been put into practical use with more or less success.

Mit der DE-OS 37 04 388 ist eine solche Reinigungseinrichtung für die Stufen von Fahrtreppen bekanntgeworden, welche als unabhängige transportable Einheit vorgesehen ist. Die Reinigungseinrichtung besteht aus einer Tragkonsole mit einer Wippe, auf welcher ein Elektromotor und eine drehbar gelagerte, über einen Keilriemen antreibbare Bürstenwalze aufgebaut ist. Zusätzlich kann in unmittelbarer Nähe der Bürstenwalze eine Absaugvorrichtung vorgesehen sein, mit welcher der abgebürstete Schmutz sofort abgesaugt wird. Für die Reinigung der Stufen wird die Reinigungseinrichtung bei stillstehender Fahrtreppe mit der Tragkonsole, beispielsweise auf die unterste hochgestellte Stufe abgesetzt. Die Wippe wird dabei mit der Bürstenwalze gegen die höhergelegene Nachbarstufe gerichtet. Bei eingeschaltetem Motor wird die rotierende Bürstenwalze mit Hilfe der Wippe manuell an die Stirnfläche der Nachbarstufe gedrückt, an dieser hochgefahren und über die horizontale Trittfläche geführt. Dabei wird die gerillte Stirnfläche und die gerillte Trittfläche dieser Stufe durch eine entsprechend ausgebildete Bürstenwalze bis auf den Rillengrund gereinigt und der losgebürstete Staub abgesogen. Für die Reinigung der nächsten Stufe wird die Reinigungseinrichtung auf die gereinigte Trittfläche gestellt und wiederum die höhergelegene Nachbarstufe gereinigt usw., bis alle im schrägen Vorlauf der Fahrtreppe sichtbaren Stufen gereinigt sind. Damit alle Stufen des ganzen Stufenbandes gereinigt werden können, wird das Stufenband durch kurzzeitiges Einschalten der Fahrtreppe etappenweise vorwärtsbewegt und wie oben beschrieben gereinigt, bis sämtliche Stufen der Fahrtreppe gereinigt sind. Ein Nachteil dieser Einrichtung liegt darin, dass für die Reinigung eine verhältnismässig unhandliche Reinigungseinrichtung nötig ist, die auf der Fahrtreppe herumgeschleppt werden muss, dass die Reinigung nur ausserhalb der Betriebszeit erfolgen kann, und dass eine gewisse Unfallgefahr besteht, wenn bei der etappenweisen Vorwärtsbewegung des Stufenbandes die Reinigungseinrichtung auf einer Stufe abgestellt bleibt und nicht von der Fahrtreppe weggebracht wird. Ein weiterer Nachteil liegt auch darin, dass ein Bereich an der Innenkante zwischen der Trittfläche und der Stirnfläche einer Nachbarstufe durch die runde Bürstenwalze nicht erreicht wird und deshalb ungenügend gereinigt werden kann.With DE-OS 37 04 388 such a cleaning device for the steps of escalators has become known, which is provided as an independent transportable unit. The cleaning device consists of a support bracket with a rocker, on which an electric motor and a rotatably mounted brush roller, which can be driven via a V-belt, is installed. In addition, a suction device can be provided in the immediate vicinity of the brush roller, with which the brushed dirt is immediately suctioned off. To clean the steps, the cleaning device is set down with the carrying console when the escalator is stationary, for example on the lowest raised step. The rocker is directed against the higher neighboring step with the brush roller. When the engine is on, the The rotating brush roller is pressed manually onto the front surface of the neighboring step with the help of the rocker, raised at this and guided over the horizontal step surface. The grooved end face and the grooved tread of this step are cleaned by a suitably designed brush roller down to the groove base and the brushed dust is sucked off. For the cleaning of the next step, the cleaning device is placed on the cleaned step surface and again the higher neighboring step is cleaned, etc., until all the steps visible in the inclined lead of the escalator are cleaned. So that all the steps of the entire step belt can be cleaned, the step belt is moved forward step by step by briefly switching on the escalator and cleaned as described above until all steps of the escalator are cleaned. A disadvantage of this device is that a relatively unwieldy cleaning device is required for cleaning, which has to be carried around on the escalator, that cleaning can only take place outside of the operating hours, and that there is a certain risk of accident if the step belt moves forward in stages the cleaning device remains parked on one step and is not moved away from the escalator. Another disadvantage is that an area on the inner edge between the tread and the end face of a neighboring step is not reached by the round brush roller and can therefore be cleaned insufficiently.

Mit der DE-PS 30 16 597 ist eine weitere Vorrichtung für die Reinigung der Stufen einer Fahrtreppe bekanntgeworden, welche in einer Umkehrstelle der Fahrtreppe fest eingebaut ist. Die Reinigungsvorrichtung besteht aus einem verstellbaren Grundrahmen mit einer auf Schienen gelagerten Tragvorrichtung mit einer festen Reinigungsbürste. Durch die Kraft von Federn wird die Reinigungsbürste in der Umkehrstelle an die vorbeifahrenden Stufen gepresst und die Trittfläche jeder Stufe bei eingeschalteter Fahrtreppe fortlaufend gebürstet und gereinigt.DE-PS 30 16 597 a further device for cleaning the steps of an escalator has become known, which is permanently installed in a reversal point of the escalator. The cleaning device consists of an adjustable base frame with a carrying device mounted on rails with a fixed cleaning brush. Due to the force of springs, the cleaning brush is pressed against the passing steps in the reversal point and the step surface of everyone Step continuously brushed and cleaned when the escalator is switched on.

Ein Nachteil dieser Reinigungsvorrichtung liegt darin, dass die Stirnflächen der Stufen nicht gereinigt werden können, weil die Stirnflächen im Bereich der Umlenkstellen nicht frei zugänglich sind.A disadvantage of this cleaning device is that the end faces of the steps cannot be cleaned because the end faces are not freely accessible in the area of the deflection points.

Der Erfindung liegt die Aufgabe zugrunde, eine Reinigungsvorrichtung vorzuschlagen, mit welcher jede Stirnfläche der Stufen fortlaufend gereinigt werden kann.The invention has for its object to propose a cleaning device with which each end face of the steps can be cleaned continuously.

Diese Aufgabe wird durch die im ersten Anspruch gekennzeichnete Erfindung gelöst.This object is achieved by the invention characterized in the first claim.

Die durch die Erfindung erreichten Vorteile sind im wesentlichen darin zu sehen, dass jede gerillte Stirnfläche der Stufen bei eingeschalteter Fahrtreppe fortlaufend gereinigt wird. Es ist also nicht nötig, die Treppe stillzusetzen und die Reinigung ausserhalb der Betriebszeit mit Hilfe von transportablen Reinigungseinrichtungen durchzuführen. Ein weiterer Vorteil liegt auch darin, dass kein zusätzliches Personal für die Reinigung der Stirnflächen erforderlich ist. Ein weiterer Vorteil liegt auch darin, dass die Reinigung fortlaufend, also sofort nach einer Verschmutzung erfolgt, wodurch ein eventuelles Festkleben von Schmutz an der Stirnfläche verhindert wird.The advantages achieved by the invention can be seen essentially in the fact that each grooved end face of the steps is continuously cleaned when the escalator is switched on. It is therefore not necessary to shut down the stairs and to carry out the cleaning outside of operating hours with the help of portable cleaning devices. Another advantage is that no additional personnel are required to clean the end faces. Another advantage is that cleaning takes place continuously, i.e. immediately after soiling, which prevents any dirt from sticking to the end face.

In den Fig. 1 und 2 ist mit 1 eine Stufe bezeichnet. Jede Stufe 1 weist eine Trittfläche 1.1 und eine Stirnfläche 1.2 auf. Die Trittfläche 1.1 und die Stirnfläche 1.2 sind gemäss Fig. 2 mit Rillen 1.4; 1.6 und mit Rippen 1.5; 1.7 versehen. In die Rillen 1.6 der Stirnfläche 1.2 greift eine Verzahnung 1.8 des rückseitigen Endes der Trittfläche 1.1 ein. Unterhalb des rückseitigen Endes der Trittfläche 1.1 ist eine Bürste 2 angeordnet, welche mit ihren Borsten 3 die Rillen 1.6 und die Rippen 1.7 der Stirnfläche 1.2 der benachbarten Stufe 1 bestreicht. Die Bürste 2 kann in einer am Stufenkörper angeordneten Halterung 4 fest eingespannt oder, als Variante, verschiebbar gelagert sein. Die Pfeile 5 geben eine Laufrichtung des Stufenbandes an, während Pfeil 6 die Relativbewegung der Stufe 1 andeutet, um die Horizontallage der Trittfläche 1.1 auch im Schräglauf des Stufenbandes zu gewährleisten.1 and 2, 1 denotes a stage. Each step 1 has a step surface 1.1 and an end surface 1.2. The tread 1.1 and the end face 1.2 are shown in FIG. 2 with grooves 1.4; 1.6 and with ribs 1.5; 1.7 provided. A toothing 1.8 of the rear end of the step surface 1.1 engages in the grooves 1.6 of the end face 1.2. A brush 2 is arranged below the rear end of the tread surface 1.1, which brushes the grooves 1.6 and the ribs 1.7 of the end face 1.2 of the adjacent step 1 with its bristles 3. The brush 2 can be firmly clamped in a holder 4 arranged on the step body or, as a variant, can be slidably mounted. The arrows 5 indicate a running direction of the step belt, while arrow 6 indicates the relative movement of step 1 in order to ensure the horizontal position of the tread surface 1.1 even when the step belt is running at an angle.

In der Fig. 3 ist mit 7 das Stufenband bezeichnet. Das Stufenband weist eine obere Umlenkung 8 und eine untere Umlenkung 9 auf. Die einzelnen Stufen des Stufenbandes 7 sind wiederum mit 1 bezeichnet. An der oberen und/oder an der unteren Umlenkung 8, 9 können Abblasvorrichtungen 10 angeordnet sein.In Fig. 3, 7 is the step belt. The step belt has an upper deflection 8 and a lower deflection 9. The individual stages of the step belt 7 are again designated 1. Blow-off devices 10 can be arranged on the upper and / or on the lower deflection 8, 9.

Die vorstehend beschriebene Reinigungseinrichtung arbeitet wie folgt: Die unter dem rückseitigen Ende der Trittfläche 1.1 einer Stufe 1 angeordnete Bürste 2 ist beim Einbau der Stufe 1 in ein Stufenband gegen die Stirnfläche 1.2 einer benachbarten Stufe 1 gerichtet. Wird die Stufe im Bereich des betretbaren Vorlaufes des Stufenbandes eingebaut, liegt die Bürste bereits beim Einbau an der Stirnfläche der benachbarten Stufe an. Wird sie im Bereich der oberen oder der unteren Umlenkstelle eingebaut, erfolgt zwischen der Bürste und der Stirnfläche der benachbarten Stufe noch keine Berührung. Bei einem kompletten Umlauf des Stufenbandes finden, beispielsweise bei der Aufwärtsfahrt, folgende Relativbewegungen zwischen jeder Bürste und der Stirnfläche der benachbarten Stufe statt: Beim Übergang von der unteren Umlenkstation in den unteren Horizontallauf des Vorlaufes bewegen sich die nacheilende Stufe mit der Bürste gegen die benachbarte Stirnfläche und zwar an der höchsten Stelle, um im Horizontallauf satt gegeneinanderzudrücken. Beim Übergang vom Horizontallauf in den Schräglauf gleitet das Stirnteil der vorauseilenden Stufe durch eine Relativbewegung gemäss Pfeil 6 zum Einhalten der Horizontallage der Trittfläche an der Bürste 2 vorbei nach oben, um im Schräglauf mit der Bürste 2 die unterste Stelle des Stirnteiles 1.2 zu erreichen. Dabei findet eine Reinigung der Stirnfläche 1.2 durch Reibung mit der Bürste 2 von oben nach unten statt. Die erreichte Lage zwischen der Bürste und der Stirnfläche wird während des Schräglaufes ohne eine Relativbewegung auszuführen beibehalten. Beim Übergang vom Schräglauf in den oberen Horizontallauf gleitet das Stirnteil der vorauseilenden Stufe durch eine Relativbewegung, wiederum zum Einhalten einer Horizontallage der Trittfläche 1.1, an der Bürste 2 vorbei nach unten, um im oberen Horizontallauf wiederum die höchste Stelle an der Stirnfläche 1.2 zu erreichen. Dabei findet eine zweite Reinigung der Stirnfläche, diesmal durch Reibung mit der Bürste von unten nach oben statt. Während des Horizontallaufes bleibt die erreichte Lage zwischen Bürste und Stirnfläche ohne Relativbewegung erhalten. Beim Übergang vom oberen Horizontallauf in die obere Umlenkstation gehen Bürste und Stirnteile auseinander und berühren sich nicht mehr. Im Rücklauf zwischen der oberen und der unteren Umlenkstation drücken die Bürste und das Stirnteil wieder gegeneinander, eine Relativbewegung verbunden mit einer Reinigung des Stirnteiles findet aber nicht mehr statt. Bei der Abwärtsfahrt ergeben sich die gleichen Relativbewegungen und Reinigungen der Stirnflächen wie bei der Aufwärtsfahrt, aber in umgekehrter Reihenfolge und Richtung. Die Stirnfläche jeder einzelnen Stufe wird somit während des Betriebes pro Umlauf zweimal gebürstet und gereinigt.The cleaning device described above works as follows: The brush 2 arranged under the rear end of the step surface 1.1 of a step 1 is directed against the end face 1.2 of an adjacent step 1 when the step 1 is installed in a step belt. If the step is installed in the area of the accessible lead of the step belt, the brush is already in contact with the front surface of the adjacent step during installation. If it is installed in the area of the upper or lower deflection point, there is still no movement between the brush and the end face of the adjacent step Contact. In the case of a complete rotation of the step belt, for example when driving upwards, the following relative movements take place between each brush and the end face of the adjacent step: When moving from the lower deflection station to the lower horizontal run of the advance, the trailing step moves with the brush against the adjacent end face and that at the highest point in order to press against each other horizontally. At the transition from horizontal running to oblique running, the front part of the leading step slides upwards past brush 2 by a relative movement according to arrow 6 to maintain the horizontal position of the tread surface, in order to reach the lowest point of front part 1.2 with brush 2 when running obliquely. The end face 1.2 is cleaned by rubbing with the brush 2 from top to bottom. The position reached between the brush and the end face is maintained during the skew without executing a relative movement. During the transition from skewing to the upper horizontal run, the front part of the leading step slides downward past the brush 2 by a relative movement, again to maintain a horizontal position of the step surface 1.1, in order to again reach the highest point on the end surface 1.2 in the upper horizontal run. The end face is cleaned a second time, this time by rubbing with the brush from bottom to top. The position reached between the brush and the end face is maintained without relative movement during the horizontal run. At the transition from the upper horizontal run to the upper deflection station, the brush and the front parts diverge and no longer touch. In the return between the upper and lower deflection stations, the brush and the front part press against each other again, but a relative movement associated with cleaning the front part no longer takes place. The downward movement results in the same relative movements and cleaning of the end faces as in the upward movement, but in reverse order and direction. The face Each individual stage is thus brushed and cleaned twice per cycle during operation.

Es ist ohne weiteres denkbar, dass im Bereich der oberen und/oder der unteren Umlenkstation des Stufenbandes zusätzlich eine auf die Stufen und/oder auf die Bürsten wirkende pneumatische Abblasevorrichtung vorgesehen ist, welche gelösten und im Rücklauf des Stufenbandes nicht abgefallenen Schmutz wegbläst, bevor die Stufe den betretbaren Vorlauf wieder erreicht.It is readily conceivable that in the area of the upper and / or the lower deflection station of the step belt, a pneumatic blow-off device acting on the steps and / or on the brushes is additionally provided, which blows away loosened dirt that has not fallen off in the return of the step belt before the Level reached the accessible lead again.

Ebenso ist es möglich, die anmeldungsgemässe Reinigungseinrichtung als Ergänzung zu einer Reinigungseinrichtung einzusetzen, die nur für die Reinigung der Trittflächen der Stufen dient.It is also possible to use the cleaning device according to the application as a supplement to a cleaning device which is only used for cleaning the treads of the steps.
