The roller body consists of a number of disc shaped single elements (14).

Description

Die Erfindung betrifft eine Schrubbwalze für eine Schrubbmaschine, die um eine Drehachse drehbar angetrieben an der fahrbaren Schrubbmaschine lagerbar ist, mit einer Lagerwelle und mit einem drehfest mit dieser verbundenen Walzenkörper aus einem formstabilisierten Fasergewirr.The invention relates to a scrubbing roller for a Scrubbing machine that is driven to rotate about an axis of rotation can be stored on the mobile scrubbing machine, with a bearing shaft and with a rotationally fixed with this connected roller body from a dimensionally stabilized Tangle of fibers.

Derartige Schrubbwalzen werden verwendet zum Polieren von Hartflächen, und es ist bekannt, als polierendes Material sogenannte formstabilisierte Fasergewirre zu verwenden. Darunter versteht man lockere Wirrlagen von Fasern, meistens Kunststoff-Fasern, die auf verschiedene Weise in der jeweiligen lockeren Wirrlage untereinander verbunden sind, so daß die Fasern in der Wirrlage festgelegt werden. Diese Verbindung kann beispielsweise erfolgen durch Wärmebehandlung und sich daraus ergebende Verschweißung, durch Beschichtung der Fasern mit anderen Kunststoffen, die sich dann miteinander verbinden, also durch Verklebung oder auch teilweise durch die wirre Anordnung der Fasern selbst. Derartige Wirrlagen haben sich als Polierkörper bewährt, allerdings führt die relativ lockere Konsistenz dieser Fasergewirre dazu, daß sich Schwierigkeiten bei der Lagerung ergeben.Such scrubbing rollers are used for polishing of hard surfaces, and it is known as a polishing Material so-called shape-stabilized fibers use. This means loose confusion of Fibers, mostly plastic fibers, on different Way in the respective loose confusion among each other are connected so that the fibers in the tangle be determined. This connection can, for example are done by heat treatment and resulting Welding, by coating the fibers with others Plastics that then bond together, So by gluing or partly by the tangled arrangement of the fibers themselves have proven themselves as a buff, however leads the relatively loose consistency of these fibers that there are difficulties in storage.

Bei bisher bekannten Schrubbwalzen hat man daher die Fasergewirrkörper in spezielle Halterungen gefaßt, beispielsweise in Naben aus Metall, die die Walzenkörper auch stirnseitig abgedeckt und zwischen sich aufgenommen haben. Es ergeben sich dadurch relativ aufwendige Herstellungsverfahren für die Walzenkörper, außerdem wird deren Gewicht gesteigert.With previously known scrubbing rollers, one therefore has the Tangled fibers in special holders, for example in metal hubs that hold the roller body also covered on the front and included between them to have. This results in relatively complex Manufacturing process for the roller body, moreover their weight is increased.

Es ist Aufgabe der Erfindung, eine Schrubbwalze der gattungsgemäßen Art so zu verbessern, daß der Aufbau wesentlich vereinfacht wird.It is an object of the invention to provide a scrubbing roller Generic type to improve so that the structure is significantly simplified.

Diese Aufgabe wird bei einer Schrubbwalze der eingangs beschriebenen Art erfindungsgemäß dadurch gelöst, daß die Lagerwelle einen unrunden Querschnitt hat und daß der Walzenkörper eine unmittelbar im Fasergewirr angeordnete zentrale Durchbrechung aufweist, die komplementär zum Querschnitt der Lagerwelle ausgebildet ist.This task is the beginning of a scrubbing roller described type according to the invention solved in that the bearing shaft has a non-circular cross-section and that the roller body is arranged directly in the tangle of fibers central breakthrough that is complementary is formed to the cross section of the bearing shaft.

Es hat sich überraschenderweise herausgestellt, daß das formstabilisierte Fasergewirr in der Lage ist, ohne irgendwelche zusätzliche Hilfskonstruktionen die Drehmomente von einer Lagerwelle aufzunehmen, wenn zwischen der Lagerwelle einerseits und dem Walzenkörper aus einem formstabilisierten Fasergewirr andererseits eine formschlüssige Verbindung hergestellt wird, bei der die Lagerwelle mit einem unrunden Querschnitt eine komplementäre Durchbrechung im Walzenkörper vollständig ausfüllt. Trotz der Flexibilität eines solchen Walzenkörpers ergibt sich eine genügende Festigkeit einer solchen Schrubbwalze, da das Material sich zwar geringfügig verformen, nicht aber vollständig ausweichen kann. Damit wird es möglich, einen Walzenkörper zu verwenden, der ausschließlich aus einem formstabilisierten Fasergewirr besteht ohne die Notwendigkeit, eine zusätzliche Nabe oder eine ähnliche Hilfskonstruktion zu verwenden.It has surprisingly been found that the shape-stabilized fiber tangle is able without any additional auxiliary constructions the torques to be taken up by a bearing shaft if between the bearing shaft on the one hand and the roller body from one shape-stabilized tangle of fibers on the other hand positive connection is established, in which the Bearing shaft with a non-circular cross-section a complementary Opening in the roller body completely filled. Despite the flexibility of such a roller body there is sufficient strength of such Scrubbing roller since the material is slightly different deform, but not completely avoid. This makes it possible to use a roller body which consists exclusively of a shape-stabilized fiber tangle exists without the need for an additional one Hub or similar auxiliary construction.

Besonders günstig ist es, wenn die Lagerwelle einen im Querschnitt kreisförmigen Kern mit radial abstehenden Leisten aufweist und wenn die zentrale Durchbrechung dementsprechend einen kreisförmigen Innenbereich und radial abstehende Schlitze umfaßt. Durch eine solche Ausgestaltung erfährt der Walzenkörper aus dem formstabilisierten Fasergewirr nicht nur eine zuverlässige Drehverbindung, sondern auch eine Stabilisierung, da der Kern und auch die abstehenden, in die Schlitze eintauchenden Leisten wie ein Skelett wirken.It is particularly favorable if the bearing shaft in Cross-section circular core with radially protruding Lasts and if the central opening accordingly a circular interior and includes radially projecting slots. By such The roller body is designed from the shape-stabilized Tangle not just a reliable one Slewing ring, but also a stabilization because the core and also the protruding ones that dip into the slots Last act like a skeleton.

Es kann vorgesehen sein, daß die Lagerwelle selbst hohl ausgebildet und formschlüssig mit einer in sie eingeschobenen, an der Schrubbmaschine antreibbar gelagerten Antriebswelle verbunden ist. Dadurch ist es möglich, die Lagerwelle in axialer Richtung von der Antriebswelle abzuziehen, so daß diese abgezogene Schrubbwalze dann außerhalb der Schrubbmaschine umgerüstet werden kann, beispielsweise durch Abziehen des Walzenkörpers von der Lagerwelle und durch Aufstecken eines neuen Walzenkörpers.It can be provided that the bearing shaft itself is hollow trained and form-fitting with an inserted into it driveably mounted on the scrubbing machine Drive shaft is connected. This makes it possible the bearing shaft in the axial direction from the drive shaft deduct so that this peeled scrubbing roller then be converted outside the scrubbing machine can, for example by pulling off the roller body from the bearing shaft and by plugging in a new one Roller body.

Bei einer besonders bevorzugten Ausführungsform ist vorgesehen, daß der Walzenkörper aus einer Vielzahl von scheibenförmigen Einzelelementen aufgebaut ist, die jeweils nur aus einem formstabilisierten Fasergewirr bestehen und eine entsprechende zentrale Durchbrechung aufweisen. Eine solche Ausgestaltung hat den Vorteil, daß diese scheibenförmigen Einzelelemente über die Länge der Lagerwelle unterschiedlich gewählt werden können, das heißt es ist möglich, die Poliereigenschaften über die Länge des Walzenkörpers individuell zu gestalten. Außerdem können mögliche unterschiedliche Abnutzungen über die Länge des Walzenkörpers ausgeglichen werden, indem Einzelelemente einfach ausgetauscht werden. Dieser Austausch ist in einfachster Weise dadurch möglich, daß die scheibenförmigen Einzelelemente nacheinander in axialer Richtung auf die Lagerwelle aufgeschoben werden.In a particularly preferred embodiment provided that the roller body from a variety of disc-shaped individual elements is built, each consist only of a dimensionally stabilized tangle of fibers and a corresponding central breakthrough exhibit. Such an embodiment has the advantage that these disc-shaped individual elements over the length the bearing shaft can be selected differently, that is, it is possible the polishing properties to design individually over the length of the roller body. In addition, possible different wear and tear balanced over the length of the roller body by simply replacing individual elements. This exchange is in the simplest way possible that the disc-shaped individual elements in succession pushed onto the bearing shaft in the axial direction will.

Bei diesen scheibenförmigen Einzelelementen ist es besonders vorteilhaft, wenn sie als Stanzteile aus einem plattenförmigen Fasergewirr hergestellt sind. Es ist sehr einfach, aus einem plattenförmig vorliegenden Fasergewirr durch Stanzen sowohl die Außenkontur als auch die Kontur der zentralen Durchbrechung in einem Arbeitsgang zu erhalten, eine weitere Bearbeitung eines solchen Einzelelements ist nicht mehr nötig, es kann dann in dieser ausgestanzten Form direkt auf die Lagerwelle aufgeschoben werden. Dies erleichtert die Herstellung erheblich.It is special with these disc-shaped individual elements advantageous if they are stamped parts from one plate-shaped tangle of fibers are produced. It is very simple, from a plate-like tangle of fibers by punching both the outer contour and the contour of the central opening in one operation to get further editing of a such a single element is no longer necessary, it can then in this punched-out form directly onto the bearing shaft be postponed. This facilitates manufacturing considerably.

Bei einer bevorzugten Ausführungsform ist vorgesehen, daß sich Teile der Lagerwelle in radialer Richtung mindestens bis zum halben Radius des Walzenkörpers erstrecken. Dadurch wird die Mitnehmefunktion und auch die Stabilisierungsfunktion der Lagerwelle verbessert, trotz der Verformbarkeit und Zusammendrückbarkeit des Fasergewirrmaterials erhält man dadurch trotzdem eine stabile Schrubbwalze, die an ihrer Außenfläche die gewünschte Verformbarkeit aufweist, die eine optimale Anlage an der zu reinigenden Fläche garantiert.In a preferred embodiment, that parts of the bearing shaft at least in the radial direction extend up to half the radius of the roller body. This will take away and also improves the stabilizing function of the bearing shaft, despite the deformability and compressibility of the This gives you a tangled material stable scrubbing roller, which has the desired on its outer surface Deformability, which is an optimal system guaranteed on the surface to be cleaned.

Die in Figur 1 dargestellte Schrubbmaschine ist stark vereinfacht und weist nur die Elemente auf, die grundsätzlich notwendig sind, um eine Hartfläche mit einer Schrubbwalze zu bearbeiten.The scrubbing machine shown in Figure 1 is strong simplified and has only the elements that are fundamental are necessary to create a hard surface with a Edit scrubbing roller.

Diese Schrubbmaschine 1 umfaßt ein Gehäuse 2 mit Rädern 3 an seinem hinteren Ende und einer Schrubbwalze 4 am vorderen Ende. Diese Schrubbwalze 4 ist um eine horizontale Achse drehbar am Gehäuse 2 gelagert und wird durch einen geeigneten Antrieb in Drehung versetzt, beispielsweise durch den in der Zeichnung dargestellten Elektromotor 5. Ein solcher Antrieb kann auch durch die Fahrbewegung der Schrubbmaschine selbst erzeugt werden, die Schrubbmaschine 1 kann mit Hilfe eines Handgriffs 6 über die zu reinigenden Fläche gefahren werden, wobei das Gehäuse 2 einerseits durch die Räder 3 und andererseits durch die Schrubbwalze 4 getragen wird.This scrubbing machine 1 comprises a housing 2 with wheels 3 at its rear end and a scrubbing roller 4 at front end. This scrubbing roller 4 is horizontal Axle is rotatably mounted on the housing 2 and is set in rotation by a suitable drive, for example by the one shown in the drawing Electric motor 5. Such a drive can also by Movement of the scrubbing machine itself are generated, the scrubbing machine 1 can be moved using a handle 6 are driven over the surface to be cleaned, whereby the housing 2 on the one hand by the wheels 3 and on the other hand is carried by the scrubbing roller 4.

Die Schrubbwalze 4 ist auf einer Antriebswelle 7 gehalten, die ihrerseits drehbar im Gehäuse 2 gelagert ist und im dargestellten Ausführungsbeispiel drehfest mit einer Seilscheibe 8 verbunden ist. Über diese Seilscheibe 8 läuft ein Treibriemen 9, der über eine entsprechende Seilscheibe 10 am Elektromotor 5 geführt ist.The scrubbing roller 4 is held on a drive shaft 7, which in turn is rotatably mounted in the housing 2 and rotatably in the illustrated embodiment with a pulley 8 is connected. About this pulley 8 runs a drive belt 9, which has a corresponding Rope pulley 10 guided on the electric motor 5 is.

Die Antriebswelle 7 hat im dargestellten Ausführungsbeispiel einen sechseckigen Querschnitt mit an den Einzelflächen radial abstehenden Leisten 11, und dieser Querschnitt entspricht vollständig dem Innenquerschnitt einer hohlen Lagerwelle 12, die in axialer Richtung auf die Antriebswelle 7 aufgeschoben wird.The drive shaft 7 has in the illustrated embodiment a hexagonal cross section with on the individual surfaces radially projecting strips 11, and this Cross-section corresponds completely to the inner cross-section a hollow bearing shaft 12 which in the axial direction the drive shaft 7 is pushed on.

Diese Lagerwelle 12 bildet einen Teil der Schrubbwalze 4, außenseitig hat sie einen kreisförmigen Querschnitt mit radial abstehenden Leisten 13, so daß sich ein im wesentlichen sternförmiger Querschnitt ergibt.This bearing shaft 12 forms part of the scrubbing roller 4, on the outside it has a circular cross section with radially protruding strips 13, so that a essential star-shaped cross section results.

Auf diese Lagerwelle 12 sind in axialer Richtung eine Vielzahl von scheibenförmigen Einzelelementen 14 aufgeschoben, die eine zentrale Durchbrechung 15 aufweisen mit einem Querschnitt, der dem Außenquerschnitt der Lagerwelle 12 komplementär ist, das heißt, die Durchbrechung weist einen zentralen kreisförmigen Teil 16 und radial davon abgehende Schlitze 17 auf, in die die Leisten 13 eintreten.On this bearing shaft 12 are one in the axial direction A large number of disc-shaped individual elements 14 are pushed on, which have a central opening 15 with a cross section that corresponds to the outer cross section of the bearing shaft 12 is complementary, that is, the opening has a central circular portion 16 and radially extending slots 17 into which the strips 13 occur.

Die scheibenförmigen Einzelelemente 14 bestehen aus einem formstabilisierten Fasergewirr, das heißt aus einer Vielzahl von in Wirrlage miteinander verschlungenen Fasern, die Hohlräume zwischen sich einschließen und die an den Berührungsstellen zumindest teilweise verbunden sind, so daß eine Stabilisierung dieser Wirrlage erreicht wird. Derartiges Material ist in einfacher Weise in Form von Platten herstellbar, und die scheibenförmigen Einzelelemente 14 werden aus solchen Platten durch einen Stanzvorgang hergestellt, bei dem die Außenkontur und die Kontur der zentralen Durchbrechung 15 ausgebildet werden.The disc-shaped individual elements 14 consist of a shape-stabilized fiber tangle, that is, from one Multitude of tangled fibers, enclose the cavities between them and the at least partially connected at the points of contact are, so that a stabilization of this confusion becomes. Such material is simple Can be made in the form of plates, and the disc-shaped Individual elements 14 are made from such plates produced a punching process in which the outer contour and the contour of the central opening 15 is formed will.

Eine Vielzahl derartiger Einzelelemente 14 sind auf die Lagerwelle 12 aufgeschoben, so daß sie stirnseitig dicht aneinander anliegen und gemeinsam einen durchgehenden Walzenkörper 18 bilden, der die gesamte Lagerwelle 12 außenseitig umgibt. Zur axialen Festlegung der scheibenförmigen Einzelelemente 14 können Sprengringe 19 verwendet werden, die in Umfangsnuten 20 an den Enden der Lagerwelle 12 eingesetzt werden. So ist es ohne weiteres möglich, nach Lösen eines solchen Sprengrings 19 die scheibenförmigen Einzelelemente 14 wieder von der Lagerwelle 12 abzuschieben und entweder in anderer Reihenfolge erneut aufzuschieben oder auszuwechseln. In dem dargestellten Ausführungsbeispiel ist der Walzenkörper 18 aus einer Vielzahl von scheibenförmigen Einzelelementen 14 ausgebildet, grundsätzlich wäre es aber auch möglich, diesen Walzenkörper 18 als durchgehende zylindrische Walze auszubilden oder ihn aus zwei oder mehr Walzen zusammenzusetzen, daß heißt mit anderen Worten, die Höhe der scheibenförmige Einzelelemente 14 kann über einen großen Bereich variieren bis zur maximalen Länge der Lagerwelle 12.A variety of such individual elements 14 are on the Bearing shaft 12 pushed so that they face lie close together and together a continuous Form roller body 18 of the entire bearing shaft 12 surrounds outside. For the axial determination of the disc-shaped individual elements 14 can snap rings 19 are used in the circumferential grooves 20 at the ends the bearing shaft 12 are used. So it is without further possible after loosening such a snap ring 19 the disc-shaped individual elements 14 again push off the bearing shaft 12 and either in another To postpone or replace the sequence again. In the illustrated embodiment, the roller body 18 from a variety of disc-shaped Individual elements 14 formed, in principle it would be but also possible, this roller body 18 as a continuous form cylindrical roller or him from two or putting together more rolls means with others Words, the height of the disc-shaped individual elements 14 can vary over a wide range up to the maximum Length of the bearing shaft 12.

Wie sich insbesondere aus den Figuren 3 und 4 ergibt, ist der Durchmesser der zentralen Durchbrechung 15 relativ groß, er kann beispielsweise im kreisförmigen Teil 16 40 bis 50% des Radius der scheibenförmigen Einzelelemente 14 betragen, die Schlitze 17 können sich in radialer Richtung noch weiter erstrecken, so daß sie beispielsweise in einem Abstand vom Mittelpunkt der Durchbrechung 15 enden, der bis zu 70% des Radius des Einzelelements 14 beträgt. Dadurch wird die Drehmitnahme verbessert, außerdem ergibt sich dadurch eine skelettartige Versteifung des Walzenkörpers 18, der selbst ausschließlich aus dem formstabilen Fasergewirr besteht und damit im gewissen Umfange flexibel und zusammendrückbar bleibt.As can be seen in particular from FIGS. 3 and 4, the diameter of the central opening 15 is relative large, it can be circular, for example Part 16 40 to 50% of the radius of the disc-shaped individual elements 14, the slots 17 can be in extend in the radial direction so that they for example at a distance from the center of the Opening 15 ends up to 70% of the radius of the Individual element 14 is. This will take the turning improved, this also results in a skeletal Stiffening of the roller body 18, the self consists exclusively of the dimensionally stable tangle of fibers and thus flexible and compressible to a certain extent remains.
