Description

Reinigungsvorrichtung Cleaning device

Die Erfindung betrifft eine Reinigungsvorrichtung für Fensterflächen, Fassadenflächen etc., mit einem Reinigungskopf mit wenigstens einer Reinigungskammer, der eine Reinigungsflüssigkeit zugeführt wird, die aus wenigstens einem Saugbereich des Reinigungskopfes wieder in einen Behälter abgesaugt wird.The invention relates to a cleaning device for window surfaces, facade surfaces, etc., with a cleaning head with at least one cleaning chamber, to which a cleaning liquid is supplied, which is sucked back into a container from at least one suction area of the cleaning head.

Dabei kann es sich um eine vollautomatische Reinigungsvorrichtung handeln, die beispielsweise ein an Seilen hängendes Gestell aufweist, auf dem der Reinigungskopf befestigt ist. Auf dem Gestell befinden sich die zugehörigen Aggregate wie Wassertank, Energieerzeuger, Pumpe etc. Das Gestell kann durch eine Steuereinrichtung in horizontaler Richtung und in vertikaler Richtung entlang der Fassade oder einer Fensterfläche bewegt werden ohne daß die Erfindung auf diese Richtungen beschränkt ist. Es kann auch vorgesehen sein, daß der Reinigungskopf von einer Bedienungsperson über die Fläche geführt wird.This can be a fully automatic cleaning device which, for example, has a frame hanging on ropes on which the cleaning head is attached. The associated units such as water tank, energy generator, pump etc. are located on the frame. The frame can be moved horizontally and vertically along the facade or a window surface by a control device without the invention being restricted to these directions. It can also be provided that the cleaning head is guided over the surface by an operator.

Bei vollautomatischen Reinigungsvorrichtungen ist das Gestell meist in einer Richtung, beispielsweise der vertikalen Richtung auf einer Führungsschiene verschieblich gelagert, während diese Führungsschiene beispielsweise mittels zweier Schlitten verschieblich auf zwei senkrecht dazu verlaufenden, also horizontalen Führungsschienen angeordnet ist. Der Reinigungskopf kann einen ziemlich großen Bewegungsbereich haben, so daß die zu dem Wasserbehälter führende Absaugleitung entsprechend lang sein muß. Bisher wird diese Saugleitung durch Schläuche gebildet, die einerseits ein beträchtliches Gewicht haben, das bei der Bewegung des Reinigungskopfes entsprechend mitbewegt werden muß und andererseits durch ihr Vorhandensein räumlich und optisch stören.In the case of fully automatic cleaning devices, the frame is usually slidably mounted in one direction, for example the vertical direction, on a guide rail, while this guide rail is arranged, for example, by means of two slides, on two guide rails which run perpendicularly thereto, that is to say horizontally. The cleaning head can have a fairly large range of motion, so that the suction line leading to the water container must be correspondingly long. So far, this suction line has been formed by hoses which, on the one hand, have a considerable weight, which must be moved when the cleaning head is moved, and, on the other hand, interfere spatially and optically due to their presence.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, für dieses Problem eine bessere Lösung anzugeben.The present invention has for its object to provide a better solution to this problem.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Patentanspruchs 1 gelöst.This object is achieved by the features of claim 1.

Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen gekennzeichnet.Advantageous embodiments of the invention are characterized in the subclaims.

Die Erfindung sieht vor, daß der Saugbereich des Reinigungskopfes über eine Leitung mit einem Schiffchen verbunden ist, das entsprechend der Bewegung des Reinigungskopfes mitbewegt wird und entlang eines gelochten Wandabschnitts einer mit dem Flüssigkeitsbehälter in Verbindung stehenden Absaugkanaleinrichtung unter Aufspreizung von Dichtlippen gleitet, die den gelochten Wandabschnitt überdecken und den Saugkanal nach außen abdichten. Der Begriff "gelocht" schließt alle geeigneten Wanddurchbrüche wie z.B. einen langgestreckten Schlitz ein.The invention provides that the suction area of the cleaning head is connected via a line to a boat which is moved in accordance with the movement of the cleaning head and which slides along a perforated wall section of a suction channel device connected to the liquid container, with the spreading of sealing lips which slide the perforated wall section cover and seal the suction channel to the outside. The term "perforated" includes all suitable wall openings such as an elongated slot.

Bei dieser Ausgestaltung der Erfindung wird nur eine kurze Leitung, beispielsweise ein kurzer Schlauch und das sogenannte Schiffchen mit der Bewegung des Reinigungskopfs mitgeführt, wobei das Schiffchen entlang des Saugkanals gleitet und das abgesaugte Flüssigkeits/Schmutzpartikel/Luft-Gemisch durch die Löcher in den Absaugkanal einführt. Der Absaugkanal kann dabei stationär gehalten sein, beispielsweise an einem Liftkorb, der auch den Flüssigkeitsbehälter trägt, mit dem der Absaugkanal in Verbindung steht, oder aber es kann auch ein Abschnitt des Absaugkanals gemeinsam mit dem Schiffchen bewegt werden, wie weiter unten noch näher erläutert wird.In this embodiment of the invention, only a short line, for example a short hose and the so-called boat, is carried along with the movement of the cleaning head, the boat sliding along the suction channel and introducing the extracted liquid / dirt particle / air mixture through the holes into the suction channel . The suction channel can be held stationary, for example on a lift basket which also carries the liquid container with which the suction channel in Connection is established, or a section of the suction channel can also be moved together with the boat, as will be explained in more detail below.

In allen Fällen entfallen die langen und damit schweren Schläuche, die beim Stand der Technik mit dem Kopf bei dessen Bewegung mitgeführt werden, so daß der Reinigungskopf leichter bewegbar ist und die mit langen Schläuchen verbundenen Platzprobleme vermieden sind.In all cases, the long and thus heavy hoses, which are carried with the head during its movement in the prior art, are eliminated, so that the cleaning head can be moved more easily and the space problems associated with long hoses are avoided.

Wie oben bereits erwähnt ist, wird der Reinigungskopf bei seiner Bewegung über eine zu reinigende Fläche, beispielsweise eine Fensterfläche, von wenigstens einer Führungsschiene geführt, die nach einem weiteren wesentlichen Gesichtspunkt der Erfindung als Rohr ausgebildet ist, das einen Bestandteil des Saugkanals darstellt. Das Führungsrohr oder vorzugsweise die Führungsrohre haben dabei vorzugsweise einen rechteckigen Querschnitt.As already mentioned above, the cleaning head is guided by at least one guide rail during its movement over a surface to be cleaned, for example a window surface, which, according to a further essential aspect of the invention, is designed as a tube which is a component of the suction channel. The guide tube or preferably the guide tubes preferably have a rectangular cross section.

Weiter wird vorgeschlagen, daß an einer Außenseite des Führungsrohrs bzw. der Führungsrohre, die Bestandteile der Saugkanalei- richtung sind, eine vorzugsweise etwa dachförmige Lochblecheinrichtung befestigt ist, die beidseitig von Gummilippen überdeckt ist, deren freie Endabschnitte das Lochblech überragen und da, wo sich das Schiffchen nicht befindet, infolge des Unterdrucks in demSaugkanal dicht aneinander anliegen. Die Lochblecheinrichtung muß aber nicht unbedingt eine Dachform haben.It is further proposed that a preferably approximately roof-shaped perforated sheet device is attached to an outside of the guide tube or the guide tubes, which are components of the suction channel device, which is covered on both sides by rubber lips, the free end portions of which protrude beyond the perforated sheet and where that The boat is not in contact due to the negative pressure in the suction channel. The perforated sheet device does not necessarily have to have a roof shape.

Dabei beinhaltet der Begriff "Lochblech" eine mit vielen Öffnungen versehene Wand, durch die im Bereich des Schiffchens das angesaugte Flüssigkeits/Schmutzpartikel/Luft-Gemischdurchtreten kann und in den übrigen Bereichen der Unterdruck des Saugkanals so auf die darüber liegenden Gummilippen einwirkt, daß diese in Anlage an das Lochblech gezogen und mit ihren Endabschnitten dichtend aneinander angelegt werden. Die Wand des Führungsrohres, die mit der etwa dachförmigen oder A-förmigen Lochblechein- richtung versehen ist, ist ebenfalls mit zahlreichen Durchbrüchen versehen, so daß die durch das Schiffchen abgegebene Flüssigkeit ins Innere des Führungsrohres gelangt und dort zu dem Behälter transportiert wird.The term "perforated plate" includes a wall with many openings through which the sucked-in liquid / dirt particles / air mixture can pass in the area of the boat and in the other areas the negative pressure of the suction channel acts on the rubber lips above it so that it Attach the system to the perforated plate and seal it with its end sections. The wall of the guide tube, which is fitted with the approximately roof-shaped or A-shaped perforated plate direction is also provided with numerous breakthroughs, so that the liquid dispensed by the boat reaches the inside of the guide tube and is transported there to the container.

Damit besteht die Saugkanaleinrichtung aus dem Führungsrohr, das den Reinigungskopf bzw. dessen Gestell mittels einer Führungseinrichtung in horizontaler oder vertikaler Richtung führt, aus der beispielsweise angenieteten, im wesentlichen dachförmigen Lochblechanordnung und den abdichtenden Gummilippen, die nur dort geöffnet werden, wo sich das Schiffchen befindet.The suction channel device thus consists of the guide tube, which guides the cleaning head or its frame by means of a guide device in the horizontal or vertical direction, of the riveted, essentially roof-shaped perforated plate arrangement, for example, and the sealing rubber lips, which are only opened where the boat is located .

In weiterer Ausgestaltung der Erfindung ist vorgesehen, daß das Schiffchen querschnittliehe eine V-förmige Aussparung hat, die der Dachform der Lochblecheinrichtung entspricht. Das Schiffchen kann ein massiver Kunststoffkörper sein, der von ein oder zwei Bohrungen durchgriffen wird, an denen mit dem Saugbereich des Reinigungskopfes verbundene Schläuche befestigbar sind, wobei die Bohrungen in die V-förmige Aussparung einmünden, so daß dort das Flüssigkeits/Schmutzpartikel/Luft-Gemisch auf die Lochblecheinrichtung auftrifft und diese passiert.In a further embodiment of the invention it is provided that the boat has a V-shaped cross-section which corresponds to the roof shape of the perforated plate device. The boat can be a solid plastic body which is penetrated by one or two bores to which hoses connected to the suction area of the cleaning head can be attached, the bores opening into the V-shaped recess so that the liquid / dirt particles / air Mixture hits the perforated sheet device and passes through it.

Das Schiffchen kann an der Halterung des Reinigungskopfes befestigt sein, die auch die Führungseinrichtung trägt, mit der die Halterung (gemeinsam mit dem Reinigungskopf) auf der Führungsschiene verschieblich sitzt. Damit das Schiffchen glatt bewegbar ist, ist es zweckmäßigerweise so gehalten, daß es in einem kleinen Abstand zu der Lochblecheinrichtung geführt wird, wobei es bei seiner Bewegung die Gummilippen öffnet, die sich hinter dem Schiffchen infolge des Unterdrucks sofort wieder schließen.The boat can be attached to the holder of the cleaning head, which also carries the guide device with which the holder (together with the cleaning head) is slidably seated on the guide rail. So that the boat can be moved smoothly, it is expediently held such that it is guided at a small distance from the perforated sheet device, and during its movement it opens the rubber lips which immediately close again behind the boat as a result of the negative pressure.

Nach einem weiteren wesentlichen Gesichtspunkt der Erfindung hat das Schiffchen in Längsrichtung sinusförmige Seitenkonturen, die dem gesamten Einführungsbereich des Luft/Schmutzpartikel/Wasser- Gemischs eine so gute Homogenität und Stetigkeit verleihen, daß Undichtigkeiten praktisch ausgeschlossen werden können. Die Dichtlippen legen sich vollkommen dicht an die sinusförmigen Außenkonturen des Schiffchens an und schließen sich unmittelbar vor und hinter dem Schiffchen. Damit kann keinerlei Wasser aus dem Absaugkanal austreten.According to a further essential aspect of the invention, the shuttle has sinusoidal side contours in the longitudinal direction, which give the entire introduction area of the air / dirt particle / water mixture such a good homogeneity and consistency that Leaks can be practically ruled out. The sealing lips lie perfectly close to the sinusoidal outer contours of the boat and close immediately in front of and behind the boat. This means that no water can escape from the suction channel.

Wie oben erwähnt, ist der Reinigungskopf (mit seiner Halterung) in einer bevorzugten Ausgestaltung der Erfindung sowohl in horizontaler Richtung als auch in vertikaler Richtung auf Führungsschienen bzw. erfindungsgemäß auf Führungsrohren geführt. Wenn der Reinigungskopf mit seiner Halterung beispielsweise verschieblich auf einem vertikalen Führungsrohr sitzt, wird das abgesaugte Flüssigkeits/Schmutzpartikel/Luft-Gemisch über ein an der Halterung angebrachtes Schiffchen in das vertikale Führungsrohr eingebracht, das Bestandteil des Absaugkanals ist.As mentioned above, in a preferred embodiment of the invention, the cleaning head (with its holder) is guided both in the horizontal direction and in the vertical direction on guide rails or, according to the invention, on guide tubes. If, for example, the cleaning head with its holder is slidably seated on a vertical guide tube, the extracted liquid / dirt particle / air mixture is introduced into the vertical guide tube via a boat attached to the holder, which is part of the suction channel.

Bei der Bewegung in horizontaler Richtung wird das vertikale Führungsrohr beispielsweise mittels zweier Schlitten auf zwei horizontalen Führungsschienen geführt. Hierbei ist erfindungsgemäß vorgesehen, daß zumindest eine dieser Führungsschienen als hohles Führungsrohr ausgebildet ist, das wiederum Bestandteil des Absaugkanals ist und daher an einer Längsseite mit einer dachförmigen Lochblecheinrichtung versehen ist, die von den oben erwähnten Dichtlippen überdeckt ist. Bei dieser Ausgestaltung der Erfindung ist im Bereich des Schlittens wiederum ein Schiffchen mit dem vertikalen Führungsrohr bzw. Absaugkanal über eine zugehörige Leitung verbunden, wobei dieses Schiffchen über die dachförmige Lochblecheinrichtung des horizontalen Führungsrohres -unter dessen Dichtlippen- gleiten kann. Auf diese Weise ist eine Verbindung zwischen dem vertikalen Abschnitt des Absaugkanals und dem horizontalen Abschnitt des Absaugkanals geschaffen. Aus dem horizontalen Absaugkanal wird das Flüssigkeits/Schmutzpartikel/Luft-Gemisch auf geeignete Weise, d.h. beispielsweise über einen angeschlossenen Schlauch, in den Flüssigkeitsbehälter abgeführt, der hierzu in seinem oberen Bereich mit einem Sauggebläse in Verbindung stehen kann, das den Unterdruck in dem gesamten Absaugkanal hervorruft.When moving in the horizontal direction, the vertical guide tube is guided on two horizontal guide rails, for example by means of two slides. It is provided according to the invention that at least one of these guide rails is designed as a hollow guide tube, which in turn is part of the suction channel and is therefore provided on one long side with a roof-shaped perforated sheet device which is covered by the sealing lips mentioned above. In this embodiment of the invention, in the area of the carriage, a shuttle is in turn connected to the vertical guide tube or suction channel via an associated line, wherein this shuttle can slide over the roof-shaped perforated plate device of the horizontal guide tube, under its sealing lips. In this way, a connection is created between the vertical section of the suction channel and the horizontal section of the suction channel. The liquid / dirt particle / air mixture is converted from the horizontal suction channel in a suitable manner, ie for example via a connected hose. discharged into the liquid container, which for this purpose can be connected in its upper region to a suction fan, which creates the negative pressure in the entire suction channel.

Durch die erfindungsgemäße Formgebung des Schiffchens bzw. der Schiffchen ist gewährleistet, daß die Gummilippen den Absaugkanal stets so dicht verschließen, daß bei der Wasserabsaugung keine Flüssigkeit aus dem Absaugkanal austreten kann. Das Mitführen langer und sperriger Schläuche entfällt, und der konstruktive Aufwand für die Anordnung des Absaugkanals ist verhältnismäßig gering, da in den Fällen, in denen der Reinigungskopf bzw. dessen Halterung oder Gestell auf Führungsschienen geführt wird, diese Führungsschienen als Hauptbestandteil des Absaugkanals herangezogen werden.The shape of the boat or boats according to the invention ensures that the rubber lips always close the suction channel so tightly that no liquid can escape from the suction channel during water suction. There is no need to carry long and bulky hoses, and the design effort for arranging the suction channel is relatively low, since in the cases in which the cleaning head or its holder or frame is guided on guide rails, these guide rails are used as the main component of the suction channel.

Der Reinigungskopf 6 ist mitsamt seiner Halterung an einem Schlitten 8 befestigt, der auf einer Führungsschiene 9 ver- schieblich sitzt, die in Fig. 1 als Z-Achse bezeichnet ist und in vertikaler Richtung verläuft. Die Führungsschiene 9 ist wiederum von zwei Schlitten 10 gehalten, die auf zwei horizontal verlaufenden Führungsschienen 11 verschieblich sitzen, die in den Figuren als X-Achse bezeichnet sind.The cleaning head 6, together with its holder, is fastened to a carriage 8 which is displaceably seated on a guide rail 9, which is designated as the Z axis in FIG. 1 and extends in the vertical direction. The guide rail 9 is in turn held by two carriages 10 which are displaceably seated on two horizontally running guide rails 11, which are designated as the X axis in the figures.

An den Enden der Führungsschienen 9 und 11 befinden sich nicht dargestellte Umlenkrollen, über die jeweils ein Antriebsriemen verläuft, dessen Enden an dem Schlitten 8 bzw. den Schlitten 10 befestigt sind. Die Riemen werden von einem Antriebsmotor 12 bzw. einem Antriebsmotor 13 angetrieben. Hierdurch wird der Reinigungskopf 6 in vertikaler und in horizontaler Richtung über eine zu reinigende Fensterscheibe bewegt.At the ends of the guide rails 9 and 11 there are deflection rollers, not shown, over which a drive belt runs, the ends of which are fastened to the slide 8 and the slide 10, respectively. The belts are driven by a drive motor 12 or a drive motor 13. As a result, the cleaning head 6 is moved in the vertical and horizontal directions over a window pane to be cleaned.

In den Figuren 3 und 4 ist weitgehend schematisch dargestellt, daß die Führungsschiene 9 ein rechteckiges Führungsrohr 14 ist, deren in Fig. 3 obere Wand mit einem umgekehrt V-förmigen oder dachförmigen Lochblech 15 verbunden ist. Das Lochblech 15 ist von aus Gummi oder einem gummiähnlichen Material bestehenden, beidseitigen Dichtlippen 16 überdeckt, deren über das dachförmige Lochblech 15 hinaus vorstehende Endabschnitte 17 in den Bereichen dicht aneinander anliegen, in denen sich nicht ein sogenanntes Schiffchen 18 befindet.In Figures 3 and 4 it is shown largely schematically that the guide rail 9 is a rectangular guide tube 14, the upper wall in Fig. 3 is connected to an inverted V-shaped or roof-shaped perforated plate 15. The perforated plate 15 is covered by rubber or a rubber-like material, on both sides sealing lips 16, the end portions 17 projecting beyond the roof-shaped perforated plate 15 abutting one another in the regions in which there is not a so-called boat 18.

Das Schiffchen 18 hat -wie wiederum besonders deutlich Fig. 6 zeigt- an seiner Unterseite eine V-förmige Aussparung 19, die der Dachform des Lochblechs 15 entspricht. Durch den Körper des Schiffchens 18 führen zwei Durchgangsbohrungen 20, 21, die in die V-förmige Aussparung einmünden.The boat 18 has, as again particularly clearly shown in FIG. 6, a V-shaped recess 19 on its underside, which corresponds to the roof shape of the perforated plate 15. Through the body of the boat 18 lead two through holes 20, 21 which open into the V-shaped recess.

Das Schiffchen 18 hat in der Draufsicht der Fig. 5 Seitenwände, die in den Endbereichen 22 eine flache Sinusform haben. Der mittlere Bereich der Seitenwände kann einen geradlinigen Verlauf haben.5, the boat 18 has side walls which have a flat sinusoidal shape in the end regions 22. The central area of the side walls can have a straight course.

Das Schiffchen 18 ist auf geeignete Weise an der in Fig. 3 insgesamt mit dem Bezugszeichen 23 bezeichneten Halterung des Reinigungskopfes 6 befestigt, wobei an der Halterung 23 gleichzeitig auch die Führungseinrichtungen bzw. der Schlitten 24 befestigt ist, mit dessen Hilfe der Reinigungskopf 6 mitsamt seiner Halterung entlang des Führungsrohres 14 geführt wird. Bei der Bewegung des Reinigungskopfes 6 mit seiner Halterung 23 entlang der Führungsschiene 14 wird demnach das Schiffchen 18 mitgeführt, das in einem kleinen Abstand über dem Lochblech 15 schwebt . Bei der Bewegung des Schiffchens 18 werden die Dichtlippen 16 geöffnet -wie die Figuren 4 und 5 deutlich zeigen- wobei sich hier die Dichtlippen 16 glatt an die Seitenflächen des Schiffchens 18 anlegen, was insbesondere durch den sinusförmigen Verlauf der Außenkonturen 22 möglich ist.The shuttle 18 is fastened in a suitable manner to the holder of the cleaning head 6, designated overall by reference numeral 23 in FIG. 3, the guide devices or the slide 24, with the aid of which the cleaning head 6 together with it, is also fastened to the holder 23 Bracket is guided along the guide tube 14. When the cleaning head 6 moves with its holder 23 along the guide rail 14, the shuttle 18 is carried along, which hovers a short distance above the perforated plate 15. When the boat 18 moves, the sealing lips 16 are opened — as clearly shown in FIGS. 4 and 5 — the sealing lips 16 here lie smoothly on the side surfaces of the boat 18, which is possible in particular due to the sinusoidal shape of the outer contours 22.

Der Saugbereich des Reinigungskopfes 6 ist über zwei nicht dargestellte Schläuche mit dem Schiffchen 18 verbunden, wobei die Schläuche in die Durchgangsbohrungen 20, 21 einmünden. Die Längswand 25 des Führungsrohres 14 enthält große Löcher, so daß das durch die Öffnungen 20, 21 in dem Schiffchen 18 angesaugte Wasser/Schmutzpartikel/Luft-Gemisch durch die Löcher des Lochblechs 15 sowie die Löcher in der Wand 25 ins Innere des Führungsrohres 14, d.h. den Absaugkanal, eintreten kann.The suction area of the cleaning head 6 is connected to the boat 18 via two hoses (not shown), the hoses opening into the through bores 20, 21. The longitudinal wall 25 of the guide tube 14 contains large holes so that the water / dirt particles / air mixture drawn in through the openings 20, 21 in the boat 18 through the holes in the perforated plate 15 and the holes in the wall 25 into the interior of the guide tube 14, ie the suction channel.

Auf entsprechende Weise kann beispielsweise die untere Führungsschiene 11 (siehe Figur 1) als Führungsrohr bzw. Absaugkanal 14 mit einem Lochblech 15 und Dichtlippen 16 ausgebildet sein, wobei der Schlitten 10 mit einem Schiffchen 18 versehen sein kann, das bei der Horizontalbewegung des Reinigungskopfes 6 unter den Dichtlippen entlang des Führungsrohres 11 gleitet, um das Wasser/Schmutzpartikel/Luft-Gemisch aus dem Führungsrohr 9 in das Führungsrohr 11 abzugeben.In a corresponding manner, for example, the lower guide rail 11 (see FIG. 1) can be designed as a guide tube or suction channel 14 with a perforated plate 15 and sealing lips 16, it being possible for the carriage 10 to be provided with a boat 18 which, when the cleaning head 6 moves horizontally, underneath the sealing lips slides along the guide tube 11 to discharge the water / dirt particles / air mixture from the guide tube 9 into the guide tube 11.

Aus dem Führungsrohr 11 gelangt das Gemisch auf geeignete Weise in den Wasserbehälter. The mixture passes from the guide tube 11 into the water container in a suitable manner.
