Abstract

The cleaner (10) has suction device (19) which removes the wet dirt particles from the space (18) around the rotating cylindrical brush (12). In line with the direction of travel (21) and close before and after the brush, the cleaner has pref. comb-like devices (22,23) which are shaped to fit into the grooves (14.1) between the ridges of the surface to be cleaned. The comb-like devices work with the brush housing (11) to seal the space around the brush and prevent the escape of dirt particles and water from the cleaner. The suction device is close to the brush within a sealed housing so that dirt and free water is promptly removed.

Description

Die Erfindung betrifft eine Vorrichtung zum Reinigen von rillenprofilierten Stegrolltreppen oder -laufstegen mit einer in einem Gehäuse angeordneten, rotierend angetriebenen Walzenbürste, einer Sprüheinrichtung für Reinigungsflüssigkeit sowie einer Absaugeinrichtung zum Entfernen der gelösten Schmutzpartikel.The invention relates to a device for cleaning grooved profiles Walkway escalators or walkways with an in a rotating brush roller arranged in a housing, a spray device for cleaning liquid and a suction device to remove the loosened dirt particles.

Rolltreppen und Laufstege mit einer gerillten Oberfläche sind nicht nur in überdachten Räumen wie Warenhäusern oder Flughäfen, sondern auch teilweise im Freien, beispielsweise bei U-Bahn-Aufgängen, im Einsatz. Insbesondere die teilweise im Freien angeordneten Rolltreppen sind starken Verschmutzungen ausgesetzt und müssen regelmäßig gereinigt werden. Zur Erleichterung dieser Reinigung wurden bereits automatische Reinigungsvorrichtungen vorgeschlagen. Die heute vor allem im Einsatz befindlichen Reinigungsgeräte führen eine Trockenreinigung mit rotierenden Bürsten durch. Aufgrund des relativ hohen für ein halbwegs befriedigendes Reinigungsergebnis erforderlichen Anpreßdruckes der Bürste bei der Trockenreinigung sind die rotierenden Bürsten der bekannten Geräte einem starken Verschleiß ausgesetzt. Diese Trockenreinigung führt außerdem zu teilweise nur mangelhaften Reinigungsergebnissen, da sich manche Schmutzarten nur mit entsprechenden Flüssigkeiten anlösen und entfernen lassen. Escalators and catwalks with a grooved surface are not just in covered spaces like department stores or airports, but also partially outdoors, for example at subway entrances, in use. In particular the partially in Free escalators are heavily soiled exposed and must be cleaned regularly. To make things easier automatic cleaning devices have already been used for this cleaning suggested. Today especially in The cleaning devices used carry out dry cleaning with rotating brushes. Because of the relative high required for a reasonably satisfactory cleaning result Contact pressure of the brush during dry cleaning the rotating brushes of the known devices are a strong one Exposed to wear. This dry cleaning also leads to sometimes poor cleaning results, because some types of dirt only with appropriate liquids dissolve and have removed.

Aus dem DE-GM 94 03 085 ist auch bereits eine Naßreinigungsvorrichtung der eingangs genannten Art bekannt. Über eine Sprüheinrichtung werden zwei seitlich nebeneinander angeordnete Walzenbürsten benetzt. Hinter der Bürste ist eine Absaugvorrichtung vorgesehen, die die schon gelösten Schmutzpartikel von der Treppenstufe oder Platte absaugt. Nachteilig bei dieser bekannten Einrichtung ist die mangelnde Wirksamkeit dieser Absaugvorrichtung, da diese nicht nur die gelösten Schmutzpartikel sondern auch große Mengen Luft aus dem umgebenden Gehäuse und von außerhalb mit anzieht. Dadurch ist es kaum befriedigend möglich, den Schmutz aus den Rillen abzusaugen. Außerdem ist die Absaugvorrichtung in einem relativ großen Abstand zur Walzenbürste angeordnet, so daß zu befürchten ist, daß Reinigungsflüssigkeit in die Lücken zwischen den einzelnen Stufen bzw. in die Lücken zwischen Treppenstufe und seitlicher Bewandung eindringen kann, bevor die Absaugvorrichtung wirksam wird.From DE-GM 94 03 085 there is already a wet cleaning device of the type mentioned above. Over a Spray device are two arranged side by side Roller brushes wetted. There is a suction device behind the brush provided the already loosened dirt particles aspirated from the step or plate. A disadvantage of this known device is the lack of effectiveness of this Suction device, as this does not only remove the loosened dirt particles but also large amounts of air from the surrounding housing and attracts from outside. As a result, it is hardly satisfactory possible to suck the dirt out of the grooves. Furthermore the suction device is at a relatively large distance arranged to the roller brush, so that it is feared that Cleaning fluid in the gaps between each Steps or in the gaps between the step and the side Wall can penetrate before the suction device is effective becomes.

Zur Vermeidung der obengenannten Probleme schlägt die Erfindung eine Vorrichtung der eingangs genannten Art vor, die erfindungsgemäß dadurch gekennzeichnet ist, daß die Absaugeinrichtung die Schmutzpartikel aus dem Rotationsraum der Walzenbürste absaugt, und in Bewegungsrichtung der Rolltreppe oder des Laufsteges vor und hinter der Walzenbürste jeweils Einrichtungen angeordnet sind, die vorzugsweise kammartig ausgebildet sind und in die Zwischenräume zwischen den Stegen der Rolltreppe oder des Laufsteges eingreifen und gemeinsam mit dem Gehäuse den Rotationsraum der Walzenbürste nach außen hin weitgehend abdichten. Bei der erfindungsgemäßen Vorrichtung wird der gelöste Schmutz also direkt an der Walzenbürste und nicht erst in einiger Entfernung dahinter abgesaugt. Hierdurch sowie durch die weitgehende Abdichtung des Rotationsraumes der Bürste nach außen, wodurch ein Unterdruck im Rotationsraum der Bürste erzeugt werden kann, ist gewährleistet, daß sämtliche Reinigungsflüssigkeit mit dem gelösten Schmutz von der Absaugeinrichtung erfaßt und entfernt wird. Es entsteht ein ständiger Sog zwischen den Zähnen der Kämme und der Rillenwandungen. Beschädigungen des Rolltreppen- oder Laufstegantriebes durch eindringende Reinigungsflüssigkeit oder Schmutz sind also nicht zu befürchten. Dabei kann die vor der Walzenbürste angeordnete kammartige Einrichtung zweckmäßigerweise Zähne aufweisen, die die Lücken zwischen den Stegen nur teilweise ausfüllen, um den Transport der Schmutzpartikel in den Rotationsraum der Walzenbürste nicht zu behindern. Der Transport der Schmutzpartikel zur Walzenbürste kann auch dadurch erleichtert werden, daß in Bewegungsrichtung der Rolltreppe oder des Laufsteges vor der Walzenbürste eine Vorreinigungs-Walzenbürste angeordnet ist, die die Sprüheinrichtung mit Reinigungsflüssigkeit benetzt. Vor Passieren der ersten Kammeinrichtung sind die Schmutzpartikel also bereits in der Reinigungsflüssigkeit gelöst und können so noch einfacher durch die kammartige Einrichtung in den Rotationsraum der Walzenbürste gelangen und von der Absaugeinrichtung abgesaugt werden. Auch das Reinigungsergebnis wird durch die Vorreinigungsbürste verbessert. Die Walzenbürste an der Absaugeinrichtung kann außerdem einen spiralförmigen Borstenbesatz aufweisen, der den Schmutz zu einer Stelle des Rotationsraumes der Bürste transportiert, an der die Absaugvorrichtung die gelösten Schmutzpartikel absaugt. Um eine Zerstörung der Reinigungsvorrichtung durch einen eventuellen seitlichen Versatz der Treppenstufen oder Platten zu verhindern, kann auf mindestens einer Seite der Vorrichtung eine in eine Rille der Stufen oder Platten der Rolltreppe oder des Laufsteges eingreifende Führungseinrichtung vorgesehen sein, wobei die Führungseinrichtung unmittelbar vor oder nach einem Trittbrett der Rolltreppe oder des Laufsteges in die Stufe oder Platte eingreift. Die Trittbretter sind jeweils mit einer kammartigen Struktur versehen, so daß die Stufen oder Platten die Trittbretter in einer definierten seitlichen Stellung verlassen bzw. unter sie einfahren. Durch die Anordnung der Führungseinrichtung unmittelbar angrenzend an ein Trittbrett wird diese definierte seitliche Position auch im Bereich der Reinigungsvorrichtung aufrechterhalten. Damit ist sichergestellt, daß die kammartigen Einrichtungen der Reinigungsvorrichtung die Übergänge zwischen den einzelnen Trittflächensegmenten kollisionsfrei passieren können.To avoid the above problems, the invention proposes a device of the type mentioned above, the according to the invention is characterized in that the suction device the dirt particles from the rotation space of the roller brush sucks, and in the direction of movement of the escalator or of the catwalk in front of and behind the roller brush are arranged, which are preferably comb-shaped are and in the spaces between the webs of the Intervene escalator or catwalk and join in with the housing the rotation space of the roller brush to the outside largely seal. In the device according to the invention the loosened dirt is directly on the roller brush and not just vacuumed off some distance behind. Hereby as well as the extensive sealing of the rotation space Brush outwards, creating a vacuum in the rotation space of the Brush can be generated, it is guaranteed that all Cleaning liquid with the loosened dirt from the suction device is detected and removed. There is a constant Suction between the teeth of the combs and the groove walls. Damage to the escalator or catwalk drive So penetrating cleaning liquid or dirt not to fear. It can be arranged in front of the roller brush comb-like device expediently have teeth, that only partially fill the gaps between the webs, to transport the dirt particles into the rotation room not to impede the roller brush. The transport of the Dirt particles to the roller brush can also be relieved be that in the direction of movement of the escalator or the catwalk a pre-cleaning roller brush in front of the roller brush is arranged, the spray device with cleaning liquid wetted. Before passing the first comb device the dirt particles are already in the cleaning liquid solved and can be even easier through the comb-like device get into the rotation space of the roller brush and be sucked off by the suction device. Even the cleaning result is improved by the pre-cleaning brush. The roller brush on the suction device can also one have spiral bristle trimmings, which the dirt too transported to a point in the rotation space of the brush which the suction device sucks off the loosened dirt particles. To destroy the cleaning device a possible lateral offset of the stairs or Preventing plates on at least one side of the Device one in a groove of the steps or plates of the Escalator or guide device engaging the catwalk be provided, the guide device directly before or after a step on the escalator or Catwalk engages in the step or plate. The running boards are each provided with a comb-like structure, see above that the steps or slabs define the running boards in a defined manner Leave the side position or retract under it. By arranging the guide device directly adjacent to a running board, this is defined on the side Maintain position also in the area of the cleaning device. This ensures that the comb-like devices the cleaning device the transitions between pass the individual tread segments without collisions can.

Weitere Vorteile können dadurch erzielt werden, daß beide Bürsten, die Vorreinigungsbürste und die Walzenbürste, mit ihren Borsten das sie umgebende Gehäuse mindestens stellenweise berühren können. Hierdurch werden an den Borsten und am Gehäuse haftende Schmutzpartikel abgestreift und damit verhindert, daß der Schmutz sich zwischen Bürste und Gehäuse ansammelt und wieder auf die Bürste zurückfällt. Es wird vielmehr eine gleichmäßige Zuführung der Schmutzpartikel zur Walzenbürste gewährleistet. Außerdem kann die Bürste durch die Anlage am Gehäuse den durch die zu reinigende Fläche erzeugten Druckkräften besser entgegenwirken. Der Bürstenkörper biegt sich auch bei starken Druckkräften nicht durch. Dadurch ist gewährleistet, daß auch Bürsten mit einer geringeren Längenstabilität stets über ihre gesamte Länge auf der zu reinigenden Fläche aufliegen. Sogar der Einsatz von Bürsten mit flexiblen Bürstenkörpern oder mit einer Borstenanordnung, die zu nicht geradlinigen Bürstenstrichkonturen führen, ist möglich.Further advantages can be achieved in that both Brushes, the pre-cleaning brush and the roller brush, with their bristles the housing surrounding them at least in places can touch. As a result, the bristles and Dirt particles adhering to the housing are stripped off and thus prevented that the dirt collects between the brush and the housing and falls back on the brush. Rather, it will an even supply of dirt particles to the roller brush guaranteed. The brush can also pass through the system the pressure forces generated by the surface to be cleaned on the housing counteract better. The brush body bends even with strong compressive forces. This ensures that even brushes with less length stability always over their entire length on the surface to be cleaned lie on. Even the use of brushes with flexible Brush bodies or with a bristle arrangement that are not too linear brush stroke contours is possible.

Im Gehäuse 11 ist außerdem eine Sprüheinrichtung 15 angeordnet, die über eine Düse 16 die Vorreinigungsbürste 13 mit Reinigungsflüssigkeit benetzt. Die Reinigungsflüssigkeit wird dabei über einen Anschluß 17 der Sprüheinrichtung 15 zugeführt. Am Rotationsraum 18 der Walzenbürste 12 greift eine Absaugeinrichtung 19 mit einem Saugstutzen 20 an. In Bewegungsrichtung 21 der Treppenstufen 14 vor und hinter dem Rotationsraum 18 der Walzenbürste 12 sind zwei kammartige Einrichtungen 22 und 23 angeordnet, die gemeinsam mit dem Gehäuseteil 11.1 den Rotationsraum 18 weitgehend nach außen abdichten. Hierdurch wird die Wirkung der Absaugeinrichtung 19 gesteigert. Die vor der Walzenbürste 12 angeordnete kammartige Einrichtung 22 weist dabei Zähne 22.1 auf (Fig. 2), die die Lücken 14.1 zwischen den Rillen 14.2 der Treppenstufe 14 nur teilweise ausfüllen und somit den Transport von Schmutzpartikeln in den Rotationsraum 18 der Walzenbürste 12 nicht behindern. Demgegenüber sind die Zähne 23.1 der kammartigen Struktur 23 hinter der Walzenbürste 12 (Fig. 3) so ausgebildet, daß sie die Lücken 14.1 zwischen den Rillen 14.2 der Treppenstufe 14 nahezu ausfüllen. Fig. 1 shows a cleaning device 10, which is not shown in detail are shown coupled to a cleaning trolley can. The device 10 has a housing 11, which according to is open at the bottom. Inside the housing 11 is a roller brush 12 and a roller-shaped pre-cleaning brush 13 arranged, which are driven in rotation. With The device 10 rests on these two brushes 12 and 13 a step 14 of an escalator with a grooved surface is provided. In the housing 11 there is also a spray device 15 arranged, the pre-cleaning brush via a nozzle 16 13 wetted with cleaning liquid. The cleaning liquid is thereby via a connection 17 of the spray device 15 fed. At the rotation space 18 of the roller brush 12 engages a suction device 19 with a suction nozzle 20 on. In the direction of movement 21 of the stairs 14 before and behind the rotation space 18 of the roller brush 12 are two comb-like devices 22 and 23 arranged together largely with the housing part 11.1 the rotation space 18 seal outside. As a result, the effect of the suction device 19 increased. The arranged in front of the roller brush 12 comb-like device 22 has teeth 22.1 (FIG. 2), the the gaps 14.1 between the grooves 14.2 of the step 14 fill out only partially and thus the transport of Dirt particles in the rotation space 18 of the roller brush 12 do not hinder. In contrast, the teeth 23.1 are comb-like Structure 23 behind the roller brush 12 (Fig. 3) so trained to fill the gaps 14.1 between the grooves 14.2 Almost fill in step 14.

Die in Pfeilrichtung 21 unter der Reinigungsvorrichtung 10 hindurchlaufenden Treppenstufen werden beim Reinigungsvorgang zunächst von der mit Reinigungsflüssigkeit benetzten Vorreinigungsbürste 13 angelöst, durch die kammartige Einrichtung 22 in den Rotationsraum 18 der Walzenbürste 12 transportiert, von dieser erfaßt und mittels deren spiralförmigem Borstenbesatz zu einer Stelle des Rotationsraumes 18 transportiert, an dem der Absaugstutzen 20 der Absaugeinrichtung 19 angreift, und abgesaugt.
