- Such machines are known from CH-A-153 771 and are used, for example, for scrubbing, moistening and wiping dry floors, but can also be used for cement slurry removal when grouting plates made of porphyry, quartzite, slate and the like. Like., In particular floor panels with rough, sure-footed surfaces, as well as when grouting clinker and mosaics are used. Absorbed water and dirt is squeezed out of the sponge-like cleaning belt, after which the cleaned sponge belt is ready to be taken up again.
- the invention has set itself the task of improving the machine so that both that picked up by the cleaning belt Dirt is better removed and the cleaning tape itself is cleaned by rinsing with a liquid, in particular water, before each new contact with the surface to be cleaned.
- the cleaning belt for dirt is in contact with a rotating liquid conveyor belt which is immersed in a container containing a liquid, in particular cleaning liquid
- the squeeze roller in the direction of rotation of the roller behind the point of contact of the liquid conveyor belt with the surface of the cleaning belt is arranged, and that the liquid container, the liquid transport belt and the cleaning belt together with the rollers receiving these belts and the squeeze roller form a mobile unit over the surface to be cleaned.
- a dirty liquid drain plate which extends over the width of the liquid conveyor belt or cleaning belt, is arranged and opens into the cleaning liquid container, so that the dirty liquid taken up by the cleaning belt is simple can be removed from the belt before the latter is loaded with new cleaning liquid.
- the liquid conveyor belt expediently runs over two deflection rollers, one of which is located in the cleaning liquid container and the other is arranged at the point of contact of the liquid conveyor belt with the cleaning belt, so that the liquid conveyor belt conveys the liquid out of the container and up in the region of the upper deflection roller releases to the cleaning belt, namely where this belt presses into the surface of the cleaning belt.
- the width of the squeeze roller advantageously corresponds to the width of the cleaning belt, and the contact pressure of the squeeze roller could be adjustable.
- the machine shown in the drawing has a roller 2, which can be moved on a surface 11 to be cleaned, which consists, for example, of grouted plates, the cleaning should be carried out in such a way that the mortar or cement veil located on the plates by mere method of Roller is removed.
- the roller surface 10 is spanned by a cleaning belt 1 made of a sponge or felt-like material.
- the surface 12 of the cleaning belt is in contact with a liquid conveyor belt 4 which runs over two parallel deflection rollers 7, 8 and is immersed in a container 6 which holds the cleaning liquid 13.
- the deflection rollers 7, 8 can be driven, just as the roller 2 can have a motor drive, but there is also the possibility of rolling the rollers over the surface 11 without a motor drive and thereby setting the liquid conveyor belt 4 in motion, since this at position 9 is in close contact with the surface 12 of the cleaning tape.
- a squeeze roller 3 Above the liquid conveyor belt 4 and in the direction of rotation A behind the latter there is a squeeze roller 3, the surface 14 of which is pressed onto the belt surface 12, the contact pressure being adjustable.
- This squeeze roller is provided with spiral grooves, not shown, which have the task of moving liquid transferred from the liquid conveyor belt 4 to the surface 12 and conveyed out of the liquid container 6 from the edges of the cleaning belt towards the center of the belt, thereby preventing that the liquid runs off laterally over the edges of the rollers.
- a dirty liquid drain plate 5 is arranged, which opens into the container 6 and serves to separate the cleaning belt 1 absorbed dirt liquid or the absorbed dirt particles, i.e. cement and mortar u. Like., Remove from the belt and steer into the container 6.
- the plate 5 has a width that corresponds approximately to the width of the cleaning belt or the liquid transport belt.
- the liquid conveyor belt is structured on its surface in such a way that it conveys liquid, for example cleaning water, from the container 6 upwards and transfers it to the surface 12 of the cleaning belt at the contact point 9, so that the cleaning belt is constantly supplied with new cleaning liquid, which indeed in the course of the cleaning process due to the fact that the cleaning container also absorbs dirty water, is dirty, but in any case is cleaner than the dirty liquid, since the dirt particles carried in it settle in the container 6.
- This is dimensioned so that it can hold a large amount of liquid and is also built so that it can be removed from the machine for cleaning purposes.
- a surface can not only be cleaned, i.e. wash, but also provided with an emulsion and even polish if the content of the liquid container 6 is selected accordingly.

- liquid is transferred from the conveyor belt to the surface 12 of the cleaning belt and, at the same time, the dirt carried along by the cleaning belt is detached from the belt and then together runs with a large part of the cleaning liquid over the inclined plate 5 in the area 6.
- the detachment of the dirt at the contact point 9 is promoted in that the liquid conveyor belt 4 executes a relative movement with respect to the cleaning belt 1, as a result of which there is an intensive frictional contact between the two belts at the contact point 9.
- the dirt that has not been released at the contact point 9 is squeezed out of the cleaning belt together with the liquid remaining on the cleaning belt by the downstream squeeze roller 3 and conveyed into the container 6 by the conveyor belt 4 running in the direction of arrow B, specifically
Description
Die Erfindung betrifft eine Maschine zum Waschen von gefliesten Oberflächen, mit einem Reinigungsband aus synthetischem Schwamm oder Filz oder einem anderen schwammähnlichen, Flüssigkeit aufnehmenden Material welches auf dem Außenumfang einer auf der zu reinigenden Oberfläche abrollenden Walze angeordnet ist und beim Abrollen den auf dieser Oberfläche befindlichen Schmutz erfaßt, und mit einer Quetschwalze, die auf das Reinigungsband einen Anpreßdruck ausübt.The invention relates to a machine for washing tiled surfaces, with a cleaning tape made of synthetic sponge or felt or another sponge-like, liquid-absorbing material which is arranged on the outer circumference of a roller rolling on the surface to be cleaned and when unrolling the dirt located on this surface detected, and with a nip roller, which exerts a contact pressure on the cleaning belt.
Derartige Maschinen sind aus der CH-A-153 771 bekannt und dienen beispielsweise zum Scheuern, Befeuchten und Trockenwischen von Böden, können jedoch auch zur Zement-Schlämme-Entfernung beim Ausfugen von Platten aus Porphyr, Quarzit, Schiefer u. dgl., insbesondere Bodenplatten mit rauhen, trittsicheren Oberflächen, sowie beim Ausfugen von Klinker und Mosaiken Verwendung finden. Aufgesaugtes Wasser und Schmutz wird aus dem schwammartigen Reinigungsband ausgepreßt, wonach das gereinigte Schwammband zur erneuten Schmutzaufnahme bereit ist.Such machines are known from CH-A-153 771 and are used, for example, for scrubbing, moistening and wiping dry floors, but can also be used for cement slurry removal when grouting plates made of porphyry, quartzite, slate and the like. Like., In particular floor panels with rough, sure-footed surfaces, as well as when grouting clinker and mosaics are used. Absorbed water and dirt is squeezed out of the sponge-like cleaning belt, after which the cleaned sponge belt is ready to be taken up again.
Ausgehend von dieser bekannten Maschine hat sich die Erfindung zur Aufgabe gemacht, die Maschine so zu verbessern, daß sowohl der von dem Reinigungsband aufgenommene Schmutz besser beseitigt wird als auch das Reinigungsband selbst vor jedem erneuten Kontakt mit der zu reinigenden Oberfläche durch Bespülung mit einer Flüssigkeit, insbesondere Wasser, gesäubert wird.Starting from this known machine, the invention has set itself the task of improving the machine so that both that picked up by the cleaning belt Dirt is better removed and the cleaning tape itself is cleaned by rinsing with a liquid, in particular water, before each new contact with the surface to be cleaned.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß das Reinigungsband zur Schmutzabgabe mit einem umlaufendem Flüssigkeitstransportband in Berührung steht, welches in einen eine Flüssigkeit, insbesondere Reinigungsflüssigkeit, enthaltenden Behälter eintaucht, wobei die Quetschwalze in Drehrichtung der Walze hinter der Berührungsstelle des Flüssigkeitstransportbandes mit der Oberfläche des Reinigungsbandes angeordnet ist, und daß der Flüssigkeitsbehälter, das Flüssigkeitstransportband und das Reinigungsband zusammen mit den diese Bänder aufnehmenden Walzen sowie die Quetschwalze eine über die zu reinigende Oberfläche fahrbare Einheit bilden.This object is achieved in that the cleaning belt for dirt is in contact with a rotating liquid conveyor belt which is immersed in a container containing a liquid, in particular cleaning liquid, the squeeze roller in the direction of rotation of the roller behind the point of contact of the liquid conveyor belt with the surface of the cleaning belt is arranged, and that the liquid container, the liquid transport belt and the cleaning belt together with the rollers receiving these belts and the squeeze roller form a mobile unit over the surface to be cleaned.
Gemäß einer vorteilhaften Ausgestaltung des Erfindungsvorschlags ist in Drehrichtung des Reinigungsbandes vor der Berührungsstelle des Flüssigkeitstransportbandes mit der Oberfläche des Reinigungsbandes eine sich über die Breite des Flüssigkeitstransportbandes oder Reinigungsbandes erstreckende Schmutzflüssigkeitsablaufplatte angeordnet, die in den Reinigungsflüssigkeitsbehälter mündet, so daß die vom Reinigungsband aufgenommene Schmutzflüssigkeit auf einfache Weise aus dem Band entfernt werden kann, bevor letzteres mit neuer Reinigungsflüssigkeit beaufschlagt wird.According to an advantageous embodiment of the proposal of the invention, in the direction of rotation of the cleaning belt in front of the point of contact of the liquid conveyor belt with the surface of the cleaning belt, a dirty liquid drain plate, which extends over the width of the liquid conveyor belt or cleaning belt, is arranged and opens into the cleaning liquid container, so that the dirty liquid taken up by the cleaning belt is simple can be removed from the belt before the latter is loaded with new cleaning liquid.
Zu diesem Zweck hat sich auch bewährt, die Schmutzflüssigkeitsablaufplatte unmittelbar unterhalb der Berührungsstelle des Flüssigkeitstransportbandes mit dem Reinigungsband anzuordnen.For this purpose it has also proven useful to arrange the dirty liquid drain plate directly below the point of contact of the liquid transport belt with the cleaning belt.
Das Flüssigkeitstransportband läuft zweckmäßigerweise über zwei Umlenkrollen, von denen sich die eine in dem Reinigungsflüssigkeitsbehälter befindet und die andere an der Berührungsstelle des Flüssigkeitstransportbandes mit dem Reinigungsband angeordnet ist, so daß das Flüssigkeitstransportband die Flüssigkeit aus dem Behälter heraus nach oben fördert und im Bereich der oberen Umlenkrolle an das Reinigungsband abgibt, nämlich dort, wo dieses Band sich in die Oberfläche des Reinigungsbandes eindrückt.The liquid conveyor belt expediently runs over two deflection rollers, one of which is located in the cleaning liquid container and the other is arranged at the point of contact of the liquid conveyor belt with the cleaning belt, so that the liquid conveyor belt conveys the liquid out of the container and up in the region of the upper deflection roller releases to the cleaning belt, namely where this belt presses into the surface of the cleaning belt.
Um zu verhindern, daß die von dem Transportband auf die Oberfläche des Reinigungsbandes aufgebrachte Flüssigkeit seitlich vom Reinigungsband abläuft bzw. aus ihm seitlich herausläuft, hat es sich bewährt, die Oberfläche der Quetschwalze mit spiralförmigen Nuten zu versehen, die die von dem Transportband auf das Reinigungsband übertragene, aus dem Vorratsbehälter herausgeförderte Flüssigkeitsmenge von den Reinigungsbandrändern in Richtung auf die Bandmitte bewegen.In order to prevent the liquid applied by the conveyor belt to the surface of the cleaning belt from running off the side of the cleaning belt or running out of it laterally, it has proven useful to provide the surface of the squeeze roller with spiral grooves that extend from the conveyor belt onto the cleaning belt Move the transferred amount of liquid, which is conveyed out of the storage container, from the cleaning belt edges towards the center of the belt.
Die Breite der Quetschwalze entspricht zu diesem Zweck vorteilhafterweise der Breite des Reinigungsbandes, und der Anpreßdruck der Quetschwalze könnte einstellbar sein.For this purpose, the width of the squeeze roller advantageously corresponds to the width of the cleaning belt, and the contact pressure of the squeeze roller could be adjustable.
Weitere vorteilhafte Ausgestaltungen der Erfindung sind den Unteransprüchen zu entnehmen.Further advantageous embodiments of the invention can be found in the subclaims.
Die Erfindung wird nachfolgend anhand der einzigen Zeichnungsfigur beschrieben, die in schematischer, perspektivischer Darstellung eine Ausführungsform der Maschine zeigt.The invention is described below with reference to the single drawing figure, which shows an embodiment of the machine in a schematic, perspective representation.
Die in der Zeichnung dargestellte Maschine weist eine Walze 2 auf, die auf einer zu reinigenden Oberfläche 11 verfahren werden kann, die beispielsweise aus verfugten Platten besteht, wobei die Reinigung derart erfolgen soll, daß der auf den Platten befindliche Mörtel oder Zementschleier durch bloßes Verfahren der Walze entfernt wird.The machine shown in the drawing has a
Die Walzenoberfläche 10 wird zu diesem Zweck von einem Reinigungsband 1 aus einem schwamm- oder filzähnlichen Material umspannt. Die Oberfläche 12 des Reinigungsbandes steht mit einem Flüssigkeitstransportband 4 in Berührung, das über zwei parallele Umlenkrollen 7, 8 läuft und in einen die Reinigungsflüssigkeit 13 aufnehmenden Behälter 6 eintaucht. Die Umlenkrollen 7, 8 können angetrieben werden, wie auch die Walze 2 einen motorischen Antrieb besitzen kann, jedoch ist auch die Möglichkeit gegeben, ohne motorischen Antrieb die Walzen über die Oberfläche 11 zu rollen und dabei das Flüssigkeitstransportband 4 in Bewegung zu setzen, da dieses an der Stelle 9 mit der Oberfläche 12 des Reinigungsbandes in enger Berührung steht.For this purpose, the roller surface 10 is spanned by a cleaning belt 1 made of a sponge or felt-like material. The
Oberhalb des Flüssigkeitstransportbandes 4 und in Walzendrehrichtung A hinter letzterem befindet sich eine Quetschwalze 3, deren Oberfläche 14 auf die Bandoberfläche 12 aufgepreßt ist, wobei sich der Anpreßdruck einstellen läßt. Diese Quetschwalze ist mit nicht dargestellten, spiralförmigen Nuten versehen, die die Aufgabe haben, von dem Flüssigkeitstransportband 4 auf die Oberfläche 12 übertragene, aus dem Flüssigkeitsbehälter 6 herausgeförderte Flüssigkeit von den Rändern des Reinigungsbandes in Richtung auf die Bandmitte zu bewegen und dadurch zu verhindern, daß die Flüssigkeit seitlich über die Walzenränder abläuft.Above the
Unmittelbar unterhalb der Berührungsstelle 9 des Flüssigkeitstransportbandes mit dem Reinigungsband ist eine Schmutzflüssigkeitsablaufplatte 5 angeordnet, die in den Behälter 6 mündet und dazu dient, die vom Reinigungsband 1 aufgenommene Schmutzflüssigkeit bzw. die aufgenommenen Schmutzteilchen, also Zement und Mörtel u. dgl., von dem Band abzunehmen und in den Behälter 6 zu lenken. Zu diesem Zweck weist die Platte 5 eine Breite auf, die in etwa der Breite des Reinigungsbandes bzw. des Flüssigkeitstransportbandes entspricht.Immediately below the point of
Das Flüssigkeitstransportband ist auf seiner Oberfläche so strukturiert, daß es Flüssigkeit, also beispielsweise Reinigungswasser, aus dem Behälter 6 nach oben fördert und an der Berührungsstelle 9 auf die Oberfläche 12 des Reinigungsbandes überträgt, so daß das Reinigungsband ständig mit neuer Reinigungsflüssigkeit versorgt wird, die zwar im Laufe des Reinigungsvorganges aufgrund der Tatsache, daß der Reinigungsbehälter auch Schmutzwasser aufnimmt, verschmutzt, jedoch in jedem Fall sauberer ist als die Schmutzflüssigkeit, da sich die in dieser mitgeführten Schmutzteilchen im Behälter 6 absetzen. Dieser ist so bemessen, daß er eine große Flüssigkeitsmenge aufnehmen kann und ist außerdem so gebaut, daß er von der Maschine zu Reinigungszwecken abgenommen werden kann.The liquid conveyor belt is structured on its surface in such a way that it conveys liquid, for example cleaning water, from the
Mit der oben beschriebenen Maschine läßt sich eine Oberfläche nicht nur reinigen, d.h. waschen, sondern auch mit einer Emulsion versehen und sogar polieren, wenn der Inhalt des Flüssigkeitsbehälters 6 entsprechend gewählt wird.With the machine described above, a surface can not only be cleaned, i.e. wash, but also provided with an emulsion and even polish if the content of the
Die erfindungsgemäße Maschine arbeitet wie folgt. Das Reinigungsband 1 nimmt wie ein Schwamm den von der Oberfläche 11 zu entfernenden Schmutz, beispielsweise Mörtel, Zement, der sich dort in einer schlammigen, breiigen Konsistenz befindet, auf und transportiert diesen beim Vorwärtsrollen der Walze 2 zur Berührungsstelle 9 des Reinigungsbandes mit dem Flüssigkeitstransportband. Dort wird von dem Transportband Flüssigkeit auf die Oberfläche 12 des Reinigungsbandes übertragen und gleichzeitig der vom Reinigungsband mitgeführte Schmutz vom Band abgelöst, der dann zusammen mit einem großen Teil der Reinigungsflüssigkeit über die schräge Platte 5 in den Bereich 6 abläuft. Die Ablösung des Schmutzes an der Berührungsstelle 9 wird dadurch gefördert, daß das Flüssigkeitstransportband 4 in bezug auf das Reinigungsband 1 eine Relativbewegung ausführt, wodurch es an der Berührungsstelle 9 zu einer intensiven Reibungsberührung zwischen den beiden Bändern kommt. Der an der Berührungsstelle 9 nicht abgelöste Schmutz wird zusammen mit der auf dem Reinigungsband verbleibenden Flüssigkeit durch die nachgeschaltete Quetschwalze 3 aus dem Reinigungsband herausgequetscht und von dem in Richtung des Pfeils B laufenden Transportband 4 in den Behälter 6 gefördert, und zwar auf dessen Oberzug 15.The machine according to the invention works as follows. The cleaning belt 1 absorbs like a sponge the dirt to be removed from the surface 11, for example mortar, cement, which is there in a muddy, pulpy consistency, and transports it when the
Dadurch wird gewährleistet, daß das die Quetschwalze 3 verlassende Reinigungsband 1 so gesäubert ist, daß es den Reinigungszweck auf der Oberfläche 11 erfüllen kann.This ensures that the cleaning belt 1 leaving the
