Description

Bodenpflegegerät mit einer rotierbaren BürsteFloor care device with a rotatable brush
Die Erfindung betrifft ein Bodenpflegegerät mit einer rotierbaren Bürste, jedenfalls weiter mit einer Absaugung im Bereich der Bürste, wobei eine Laufrolle zur Nerfahrerleichterung vorgesehen ist.The invention relates to a floor care appliance with a rotatable brush, in any case further with an extraction in the brush, wherein a roller is provided for Nerfahrerleichterung.
Bodenpflegegeräte der in Rede stehenden Art sind bekannt, so bspw. in Form von Norsatzgeräten für Haushalts-Staubsauger oder auch in Form von stielgeftthrten Kehrgeräten. Diese weisen rotierbare Bürsten auf, zur Kehrbeaxbeitung des zu reinigenden Bodens, wozu die Bürsten in der Regel quer zu einer üblichen Nerf ahrrichtung, bei welcher der Benutzer das Gerät vor sich her schiebt ausgerichtet sind und wobei weiter die Bürsten mit ihren Borstenbtische-n nach unten über den Geräteboden hinausragen. Zur Nerfahrerleichterung weisen solche Bodenpflegegeräte zudem mindestens eine Laufrolle auf, über welche sich das Gerät auf dem zu reinigenden Boden abstützt.Floor care equipment of the type in question are known, so for example. In the form of Norsatzgeräten for household vacuum cleaners or in the form of stielgeftthren sweeping equipment. These have rotatable brushes for sweeping the floor to be cleaned, for which purpose the brushes are generally oriented transversely to a conventional direction of movement, in which the user pushes the appliance in front of him, and furthermore the brushes with their bristle tables-n downwards protrude beyond the bottom of the device. For Nerfahrerleichterung such floor care devices also have at least one roller over which the device is supported on the floor to be cleaned.
Im Hinblick auf den zuvor beschriebenen Stand der Technik wird eine tec-hrύsctie Problematik der Erfindung darin gesehen, ein Bodenpflegegerät der in Rede stehenden Art insbesondere hinsichtlich einer erleichterten Handhabung weiter zu verbessern.In view of the above-described prior art, a tec-hrύsctie problem of the invention is seen in a soil care device of the type in question, in particular with regard to ease of handling to further improve.
Diese Problematik ist zunächst und im Wesentlichen durch den Gegenstand des Anspruchs 1 gelöst, wobei darauf abgestellt ist, dass die Laufrolle von der Bürs- te durchgesetzt ist. Zufolge dieser erfindungsgemäßen Ausgestaltung ist ein Bodenpflegegerät geschaffen, welches mit einer Laufrolle versehen ist, die in direktem Bodenbearbeitungsbereich angeordnet ist. Insbesondere ist die erfindungsgemäße Anordnung der Laufrolle bei Bodenpflegegeräten, welche mit einer Absaugung im Bereich der Bürste arbeiten von Vorteil. So ist bei den bekannten Geräten zur Verhinderung des Ansaugens des Bodenpflegerätes an den Teppichboden bekannt, eine Laufrolle mit einer zentrisch angeordneten Achse in Nerfahrrichtung vor oder hinter dem durch die Bürste durchsetzten- Saugmund im Bereich des Gerätebodens anzuordnen. Weitere Maßnahmen zur Verhinderung des Ansaugens bestehen bspw. durch Anordnung von Stegen im Saugmund. Werden jedoch Laufrollen in Verfahrrichtung vor dem Saugmund bzw. vor der Bürste angebracht, ist diese zwangsläufig weiter von der Stirnseite des Bodenpflegegerätes entfernt, was einen Nachteil bezüglich der Frontabsaugung bedeutet. Werden Laufrollen hinter dem Saugmund bzw. der Bürste angeordnet, wird insbesondere ein Teppichboden im stirnseitigen Bereich des Geräts häufig so weit nach oben angesaugt, dass es zu einerThis problem is solved, first and foremost, by the subject matter of claim 1, with the object being that the roller is enforced by the brush. According to this embodiment of the invention, a floor care device is provided, which is provided with a roller, which is arranged in direct tillage area. In particular, the arrangement according to the invention of the roller in floor care appliances which work with an extraction in the region of the brush is advantageous. So is in the known devices for preventing the suction of the soil care device the carpet known to arrange a roller with a centrally arranged axis in Nerfahrrichtung before or behind the penetrated by the brush suction mouth in the area of the bottom of the device. Further measures to prevent the suction exist, for example. By the arrangement of webs in the suction mouth. However, if rollers mounted in the direction of travel in front of the suction mouth or in front of the brush, this is inevitably further away from the end face of the floor care device, which means a disadvantage with respect to the front exhaust. If rollers are arranged behind the suction mouth or the brush, in particular a carpet in the frontal region of the device is often sucked up so far that it becomes a
Selbstabdichtung und somit zu hohen Schiebekräften kommt. Insofern erweist sich die erf indungsgemäße Anordnung der Laufrolle als vorteilhaft, da hierdurch die Bürste bzw. der von der Bürste durchsetzte Saugmund weiter nahe dem stirnseitigen Bereich des Bodenpflegegerätes angeordnet sein kann, zur verbesserten Frontabsaugung bzw. Bürstbearbeitung. Des Weiteren ist die erfindungsgemäße Laufrolle im kritischen Bereich angeordnet, so in dem Bürst- und gegebenenfalls Saugbereich, so dass insbesondere bei einem Bodenpflegegerät, bei welchem zugleich zur Bürstbearbeitung eine Absaugung erfolgt, ein zu bearbeitender Teppichbodenabschnitt durch die Laufrolle niedergehalten wird. Einem Ansaugen und somit einer Selbstabdichtung ist entgegengewirkt. Zufolge dessen sind auch insbesondere bei einer Bürst- und Saugbearbeitung eines Teppichbodens die Schiebekräfte reduziert. Um hierbei die Funktion der rotierenden Bürste nicht zu behindern, ist die Laufrolle so gestaltet, dass die Bürste durch die Laufrolle hindurch ragt. Bevorzugt sind hierbei Laufrolle und Bürste annähernd koaxial zueinander angeordnet. Des Weiteren erfährt die Bürste durch die erfindungsgemäße Anordnung der Laufrolle einen definierten Bodenabstand. Diesbezüglich ist weiter vorgesehen, dass die Laufrolle eine Führung aufweist, die eine Durchtrittsöffnung für die Bürste belässt, wobei weiter bevorzugt die Führung sich nur über einen Teil des Umf angs der Laufrolle erstreckt, so bspw. über 25 bis 75 %, bevorzugt etwa 30 % des Umfangs. Diese Führung definiert die geometrische Achse der Laufrolle und kann bspw. als Gleit ührung gebildet sein. Des Weiteren ist diesbezüglich bevorzugt, dass sich die Führung über einen in Betriebsstellung des Bodenpflegegeräts unteren Umfangsabschnitt erstreckt. Die Führung der Laufrolle ist in einer Ausführungsf orm quer zur Rotationsachse der Laufrolle gehaltert, so insbesondere im Bereich des Gerätegehäuses. So kann weiter die Halterung im Bereich des Bürst- bzw. Saugraumes ausgeführt sein. In einer vorteilhaften Weiterbildung des Erfindungsgegenstandes ist vorgesehen, dass die Führung zugleich einen Nabenabschnitt bildet, die Laufrolle jedoch sich relativ zu dem Nabenabschnitt bewegt. Die Führung ist hierzu schalenartig ausgeformt zur Bildung eines sich über einen Teil des Umfangs der Laufrolle erstreckenden Nabenabschnitts, auf welchem radial außen die ringförmig ausgeformte Laufrolle geführt ist. Letztere durchsetzt die Führung in einem sich nach radial außerhalb erstreckenden Abschnitt. Dieser Abschnitt dient zugleich der Halterung der Führung bzw. des die Laufrolle führendenSelf-sealing and thus high sliding forces comes. In this respect, the erf indungsgemäße arrangement of the roller proves to be advantageous, as a result, the brush or the penetrated by the brush suction mouth can be further arranged near the frontal region of the floor care device for improved Frontabsaugung or brushing. Furthermore, the roller according to the invention is arranged in the critical area, so in the brushing and optionally suction area, so that in particular in a floor care device, wherein at the same time for brushing an extraction takes place, a carpet section to be processed is held down by the roller. An intake and thus a self-sealing is counteracted. As a result, the sliding forces are reduced especially in a brushing and suction processing of a carpet. In order not to hinder the function of the rotating brush, the roller is designed so that the brush protrudes through the roller through. Roller and brush are preferably arranged approximately coaxially with each other. Furthermore, the brush undergoes a defined ground clearance by the inventive arrangement of the roller. In this regard, it is further provided that the roller has a guide which leaves a passage opening for the brush, wherein more preferably the guide extends only over part of the circumference of the roller, for example over 25 to 75%, preferably approximately 30% of the scope. This guide defines the geometric axis of the roller and can, for example, be formed as a sliding guide. Furthermore, in this regard, it is preferable for the guide to extend beyond a lower peripheral section in the operating position of the floor care appliance. The leadership of the roller is supported in a Ausführungsf orm transverse to the axis of rotation of the roller, so in particular in the field of device housing. Thus, the holder can be carried out in the region of the brushing or suction chamber. In an advantageous development of the subject invention it is provided that the guide also forms a hub portion, but the roller moves relative to the hub portion. The guide is for this purpose shell-shaped to form a over a part of the circumference of the roller extending hub portion on which radially outwardly the annular shaped roller is guided. The latter passes through the guide in a radially outwardly extending section. This section also serves to hold the guide or the roller leading
Nabenabschnitts. Die von der Laufrolle durchsetzte Durchbrechung in diesem Abschnitt ist querschnittsmäßig so ausgebildet, dass die Laufrolle formschlüssig an der Führung gehaltert ist. So kann in einer bevorzugten Ausführungsform die einen Nabenabschnitt ausbildende Führung mit den sich nach radial außerhalb erstreckenden Abschnitten sekantenartig der Laufrolle zugeordnet sein, wobei im Bereich der Abschnitte eine Durchdringung durch die Laufrolle erreicht ist. Der durchdrungene Bereich in den Abschnitten ist querschnittsmäßig und hinsichtlich der Krümmung in Umf angsrichtung der Laufrolle an Letztere angepasst zur rotationsbeweglicheη, jedoch achsfesten Halterung der Laufrolle sowohl in Laufrollenachsrichtung als auch quer hierzu. Die Bürste weist einen Bürstenachskörper auf und hieraus radial vorstehende Borstenbüschel. Diesbezüglich wird vorgeschlagen, dass die Durchtrittsöffnung der Laufrolle größer gewählt ist als der Durchmesser des Bürstenachskörpers aber kleiner als eine größte Radialerstreckung der Borstenbüschel. So kann die Bürste im Durchsetzüngsbereich zu der Laufrolle umfangsmäßig borstenfrei gehalten sein. Dadurch bedingt, dass die D-urditrittsöffnung der Laufrolle kleiner gewählt ist als eine größte Radialerstreckung der Borstenbüschel, ist auch bei Abstützung der Laufrolle auf einem Teppichboden oder dgl. die Bürstbearbeitung dieses Bodens gewährleistet. Darüber hinaus ist die Durchtrittsöffnung der Laufrolle so gewählt, dass eine kippbeweglich gelagerte Bürste - so bspw. zur Reaktion auf Bodenurnebenheiten - frei in dem durchsetzten Bereich der Laufrolle bewegb-ar ist. Die Lagerung der Laufrolle kann auch durch eine Gleitführung erreicht sein, bei welcher die kreisringförmige Laufrolle an ihrer Innenwandung mittels Rollen abgestützt ist. Alternativ kann die Laufrolle achsenfrei an- ihrem Außenumfang abgestützt sein. Eine solche Abstützung kann nach Art eines Rollen- oder Zylinderlagers vorgenommen sein, zur Ausformung einer Rollen- bzw. Außengleitführung. In einer beispielhaften Ausgestaltung sind über den Umfang der Laufrolle, welche ringförmig ausgebildet ist, mehrere, so bevorzugt drei gleichmäßig zueinander beabstandete Abstützungen vorgesehen, wobei die diese ausformenden Rollenoder Zylinderlager im Bereich des Gerätegehäuses, so weiter bevorzugt im Bereich des Bürst- bzw. Saugraumes gehaltert sind.Hub section. The penetrated by the roller opening in this section is cross-sectionally designed so that the roller is positively held on the guide. Thus, in a preferred embodiment, the leadership forming a hub portion guide with the radially outwardly extending portions are secant associated with the roller, wherein in the region of the sections a penetration is achieved by the roller. The penetrated area in the sections is of a cross-sectional nature and, with respect to the curvature in the circumferential direction of the caster, is adapted to the latter for rotationally movable but axially fixed support of the caster both in the caster axle direction and transversely thereto. The brush has a Bürstenachskörper and here radially projecting bristle tufts. In this regard, it is proposed that the passage opening of the roller is selected to be larger than the diameter of the Bürstenachskörpers but smaller than a maximum radial extent of the bristle tufts. Thus, the brush may be circumferentially bristle-free in the penetration area to the roller be held. Due to the fact that the D-urditrittsöffnung the roller is chosen smaller than a maximum radial extent of the bristle tufts, the brushing of this floor is guaranteed even when supporting the roller on a carpet or the like. In addition, the passage opening of the roller is selected so that a tiltably mounted brush - so, for example, to respond to Bodenurnebenheiten - is free in the enforced region of the roller bewegb-ar. The bearing of the roller can also be achieved by a sliding guide, in which the annular roller is supported on its inner wall by means of rollers. Alternatively, the roller can be supported on its outer periphery without axes. Such a support can be made in the manner of a roller or cylinder bearing, for forming a roller or outer sliding guide. In an exemplary embodiment, a plurality of, preferably three equally spaced supports are provided over the circumference of the roller, which is annular, wherein these forming roller or cylinder bearings in the area of the device housing, so further preferably held in the region of the brush or suction are.

In dem Saugraum 7 sind des Weiteren elektromotorisch antreibbare, rotierbare, Bürsten 9 angeordnet, welche sich gleichfalls quer zur Vorschubrichtung r über die Saugraumbreite erstrecken. Die Borstenbüschel 19 der Bürsten 9 ragen unterseitig über den Geräteboden 11 durch den Saugmund 8 zur Bürstbearbeitung des Bodens 4 vor.The connecting piece 6 is in fluid communication with a - in the usual direction of feed r considered - sthmseitigen suction 7, which extends transversely to the feed direction r in the floor care device 5 and downward, ie facing the floor to be cared 4 forms a slot-like suction 8. In the suction chamber 7 further drivable, rotatable brushes 9 are arranged, which also extend transversely to the feed direction r over the Saugraumbreite. The bristle tufts 19 of the brushes 9 project on the underside over the device base 11 through the suction mouth 8 for brushing the bottom 4.
Wie insbesondere in der Unteransicht in Fig. 2 zu erkennen, ist das Bodenpflegegerät 5 im rückwärtigen, d. h. dem Anschlussstutzen 6 zugewandten Bereich mit Laufrollen 12 versehen, welche in üblicher Weise um einen im Gerätegehäuse 13 verankerte Achskörper 14 drehbar gelagert sind.As can be seen in particular in the bottom view in Fig. 2, the floor care device 5 in the rear, d. H. The connecting piece 6 facing area provided with rollers 12 which are rotatably mounted in the usual manner about an anchored in the device housing 13 axle body 14.
Eine weitere Abstützung erfährt das Bodenpflegegerät 5 im in Vorschubrichtung r betrachteten stinseitigen Bereich, so konkret im Bereich des durch die Bürsten 9 bzw. durch die Borstenbüschel 19 durchsetzten Saugmunds 8.A further support is experienced by the floor care device 5 in the side area considered in the feed direction r, so concretely in the area of the suction mouth 8 penetrated by the brushes 9 or by the bristle tufts 19.
Hier sind weitere Laufrollen 15 vorgesehen, welche mittig in Erstreckungsrichtung einer jeweiligen Bürste 9 angeordnet von diesen durchsetzt werden.Here are further rollers 15 are provided, which are arranged centrally in the extension direction of a respective brush 9 interspersed by these.
In den Fig.3 bis 7 ist eine erste Ausführungsform dieser im Stirnbereich des Bodenpflegegeräts 5 angeordneten Laufrollen 15 dargestellt. Diese weisen zunächst eine Führung 16 auf, die eine Durchtrittsöffnung 17 für die jeweilige Bürste 9 belässt, die größer gewählt ist, als der Durchmesser d eines Bürs- tenachskörpers 18, jedoch größer als eine Radialerstreckung der radial aus dem Bürstenachskörper 18 vorstehenden Borstenbüschel 19 (vgl. Fig.3). In dem, die Laufrolle 15 durchsetzenden Axialabschnitt ist der Bürstenachskörper 18 borstenfrei gehalten. Die geometrische Rotationsachse der Laufrolle 15 ist durch die Führung 16 definiert. Die Führung 16 erstreckt sich nur über einen Teil des Umfangs der Laufrolle 15, so in dem dargestellten Ausführungsbeispiel -etwa über ein Drittel des Rollenumfangs, wobei weiter die Führung 16 zugleich einen Nabenabschnitt 20 für die im Wesentlichen ringfömig ausgebildete Laufrolle 15 bildet. Beidseitig endseitig dieses im Querschnitt schalenförmigen Nabenabschnitts 20 sind in etwa radial sich nach außen erstreckende Abschnitte 21 angeformt, welche Abschnitte 21 von der ringförmigen Laufrolle 15 durchsetzt sind.FIGS. 3 to 7 show a first embodiment of these rollers 15 arranged in the front region of the floor care appliance 5. These initially have a guide 16, which leaves a passage opening 17 for the respective brush 9, which is selected to be larger than the diameter d of a Bür- tenachskörpers 18, but greater than a radial extent of the radially from the Bürstenachskörper 18 protruding bristle tufts 19 (see Fig. 3). In the, the roller 15 passing through axial portion of the Bürstenachskörper 18 is held bristle-free. The geometric axis of rotation of the roller 15 is defined by the guide 16. The guide 16 extends only over part of the circumference of the roller 15, so in the illustrated embodiment, about one third of the roller circumference, wherein further the guide 16 also forms a hub portion 20 for the substantially ringfömig formed roller 15. On both sides of this end in cross-section shell-shaped hub portion 20 are formed approximately radially outwardly extending portions 21, which portions 21 are penetrated by the annular roller 15.
Die so ausgeformte Führung 16 ist sekantenaxrtig dem in Arbeitsstellung des Bodenpflegegeräts 5 unteren Bereich der Laufrolle 15 zugeordnet. Die Laufrolle 15 stützt sich hierbei wandungsinnenseitig an dem Nabenabschnitt 20 ab, wobei ein radiales Außenmaß dieses Nabenabsch itts 20 kleiner gewählt ist als das radiale Außenmaß der Laufrolle 15.The thus formed guide 16 is sekantenaxrtig assigned to the lower working area of the floor care device 5 area of the roller 15. The roller 15 is supported in this case on the inside wall of the hub portion 20, wherein a radial outer dimension of this Nabenabsch itts 20 is selected to be smaller than the radial outer dimension of the roller 15th
Über die in etwa radial abragenden Abschnitte 21 ist die Führung 16 quer zur Rotationsachse der Laufrolle 15 gehaltert, wozu die Abschnitte 21 in dem Gerätegehäuse 13, so insbesondere im Bereich des Saugraums 7 gefesselt sind.About the approximately radially projecting portions 21, the guide 16 is supported transversely to the axis of rotation of the roller 15, to which the sections 21 in the device housing 13, so in particular in the region of the suction chamber 7 are tied.
Die Anordnung und Festlegung der Führung: 16 ist weiter so gewählt, dass die Laufrolle 15 mit einem Kreisabschnitt nach unten über den Geräteboden 11 überragt.The arrangement and determination of the guide: 16 is further selected so that the roller 15 projects beyond a circular section down over the bottom of the device 11.
Die ringförmige Laufrolle 15 ist an der Führung 16 f ormschltissig gehaltert, wozu die ringförmige Laufrolle 15 einen in etwa doppel-T-förmigen Querschnitt aufweist. Die von der Laufrolle 15 durchsetzten Abschnitte 21 besitzen querschnittsmäßig entsprechend ausgeformte Durchsetzungsöffnungen 22, welche in Dickettrichtung der Abschnitte 21 an der Kreisbogenkrümmung der Laufrolle 15 amgepasst ausgeformt sind (vgl. Fig. 6 und 7). Zufolge dieser Ausgestaltung ist die Laufrolle 15 an der Führung 16 bei freier Drehbeweglichkeit formschlüssig gehaltert. Die Abstützung des Bodenpflegegeräts 5 über die Laufrollen 15 und auch ein Anheben des Bodenpflegegeräts 5 führen nicht zu einer Relativverlagerung der Laufrolle 15 gegenüber der Führung 16 in Querrichtung zur Rotationsachse.The annular roller 15 is fixedly held on the guide 16, for which purpose the annular roller 15 has an approximately double-T-shaped cross-section. The portions 21 penetrated by the roller 15 have, in cross-section, correspondingly shaped through-openings 22 which are formed in the thickness direction of the sections 21 at the arc of the circular roller 15 (see FIGS. According to this embodiment, the roller 15 is held positively on the guide 16 with free rotational movement. The support of the floor care device 5 via the rollers 15 and also a lifting of the floor care device 5 do not lead to a relative displacement of the roller 15 relative to the guide 16 in the transverse direction to the axis of rotation.
Dadurch bedingt, dass die Führung 16 über den Umfang der Laufrolle 15 nur partiell ausgebildet ist, ist die von der Bürste 9 zu durchsetzende Durchtrittsöffnung 17 durch den Nabenabschnitt 20 und durch die mittige Öffnung der ringförmigen Laufrolle 15 gebildet. Ein lichtes Maß dieser Durchtrittsöffnung 17 entspricht etwa dem 1,2 bis 1,5-fachen des Bürstenkörper-Durchmessers d. Die von dem Bürstenkörper 18 radial abragenden Borstenbüschel 19 sind in ihrem Erstreckungsmaß so gewählt, dass diese mit ihren freien Enden radial über die Lauf rollenaußenfläche ragen.Due to the fact that the guide 16 is only partially formed over the circumference of the roller 15, the passage opening 17 to be penetrated by the brush 9 is formed by the hub section 20 and by the central opening of the annular roller 15. A clear dimension of this passage opening 17 corresponds approximately to 1.2 to 1.5 times the brush body diameter d. The bristle tufts 19 projecting radially from the brush body 18 are selected in their extension dimension so that they protrude with their free ends radially over the running roller outer surface.
Zufolge der erfindungsgemäßen Ausgestaltung kommt den Laufrollen 15 eine Doppelfunktion zu. So dienen sie zum einen der Verfahrerleichterung und zum anderen als Niederhalter im Bereich des Saugmundes 8. Insbesondere Teppichböden, welche durch den im Saugraum 7 anstehenden Unterdruck leicht angesaugt werden können, was zu einem Verschluss des Saugraumes 7 und somit zu einer Erhöhung der Schiebekräfte führen würde, werden im kritischen Bereich durch die Laufrollen 15 niedergehalten.According to the embodiment of the invention, the rollers 15 has a double function. In particular, carpets, which can be easily sucked by the imminent vacuum in the suction chamber 7, which would lead to a closure of the suction chamber 7 and thus to an increase in the sliding forces , Are held down in the critical area by the rollers 15.
Eine alternative Ausführungsform zur axialen Festlegung der Laufrollen 15 ist in den Fig. 8 und 9 dargestellt. Diese Laufrollen 15 sind achskörperfrei ausgebildet, so dass die durch die ringförmige Ausbildung der Laufrolle 15 ausgebildete mittige Öffnung zugleich die Durchtrittsöffnung 17 für die Bürste 9 bildet. Die Abstützung der Laufrolle 15 erfolgt im Bereich ihres Außenumfangs, wozu in Rotationsrichtung betrachtet beidseitig der Laufrollen 15 Zylinderlager 23 vorgesehen sind, welche mit den gefasten Randkanten 24 der Laufrolle 15 zusammenwirken. Hierbei sind die Zylinderlager 23 etwa in einem Winkel von 45° zur Ebenenerstreckung der Laufrolle 15 ausgerichtet, wobei weiter über den Umfang der Laufrolle 15 verteilt drei Zylinderlager- Paare, jeweils einen Winkel von 120° zwischen sich einschließend, vorgesehen sind. Die Zylinderlager 23 sind hierbei im Bereich des Gerätegehäuses 13, insbesondere im Bereich des Saugraumes 7 gehaltert.An alternative embodiment for axially fixing the rollers 15 is shown in Figs. 8 and 9. These rollers 15 are formed achsörperfrei, so that formed by the annular formation of the roller 15 central opening at the same time forms the passage opening 17 for the brush 9. The support of the roller 15 takes place in the region of its outer periphery, including viewed in the direction of rotation on both sides of the rollers 15 cylindrical bearings 23 are provided, which with the beveled edges 24th the roller 15 cooperate. Here, the cylindrical bearings 23 are aligned approximately at an angle of 45 ° to the plane extension of the roller 15, wherein further distributed over the circumference of the roller 15 three Zylinderlager- pairs, each including an angle of 120 ° between them, are provided. The cylindrical bearings 23 are in this case held in the region of the device housing 13, in particular in the region of the suction chamber 7.
