It includes at least one rotatably mounted drive roll (6) whose axis is parallel to that of the roll (2) and which can be pressed against and used to drive the roll to be cleaned by friction. The device also includes at least one, also axis-parallel, brush roll (10) which can be simultaneously pressed against the roll to be cleaned and which brushes and cleans the roll as a result of relative motion between the two. A drive mechanism (8) rotates the drive roll (6) and the brush roll (10). At least one receiver (32) is located in the path of the displaced dirt in such a way as to catch the dirt as it is removed. Pref. an application system (24) for a cleaning fluid is arranged to deliver the fluid onto the roll being cleaned and/or the drive and brush rolls. The cleaning device is portable and has two handles (42, 44) spaced apart along the axis of the drive roll, one of which carries the switch for the drive motor, and the other a switch or pump actuator (44) for the cleaning fluid application. The device may have a carrier frame with two wheels on which it is moved along the length of the roll to be cleaned. At least one wiper (22) is provided, which projects into the brush and removes dirt from it. The drive mechanism is detachably coupled with the driven roll. The brush roll has two co-axial free running wheels (16, 18) which bear against and are driven by the roll to be cleaned. These fix the min. proximity of the brush roll to the roll to be cleaned. <IMAGE>

Description

Die Erfindung betrifft ein Gerät zur Reinigung von Walzen, insbesondere von Papierleitwalzen in Druckmaschinen, gemäß dem Oberbegriff von Anspruch 1.The invention relates to a device for cleaning rollers, in particular paper guide rollers in printing machines, according to the preamble of claim 1.

Papierleitwalzen von Druckmaschinen haben einen kleinen Durchmesser und werden in der Regel nicht direkt angetrieben, sondern sie werden durch die von anderen Walzen angetriebene Papierbahn durch Reibung in Drehung versetzt. Auf der Umfangsfläche der Papierleitwalzen setzt sich nach einiger Betriebszeit fest haftender Schmutz ab, insbesondere Papierfasern, Druckerschwärze und Staub, der regelmäßig entfernt werden muß, um eine Verunreinigung der Papierbahn zu vermeiden.Paper guide rolls of printing machines have a small diameter and are usually not driven directly, but are rotated by the paper web driven by other rolls by friction. After a period of operation, dirt adhering to the peripheral surface of the paper guide rollers, in particular paper fibers, printing ink and dust, has to be removed regularly to avoid contamination of the paper web.

Beim Stand der Technik werden die Leitwalzen einer angetriebenen Papierbahn dadurch gereinigt, daß die Leitwalzen abgebremst werden, so daß durch die Relativbewegung zwischen der angetriebenen Papierbahn und der sich langsamer drehenden Papierleitwalze die mit Reinigungsmittel befeuchtete Papierbahn den Schmutz von der Walze abwischt. Gemäß einer anderen bekannten Reinigungsmethode wird die Papierleitwalze von Hand gedreht und der Schmutz von Hand abgewaschen. Bei der einen Methode wird viel Papier benötigt, bei der anderen ergeben sich lange Maschinen-Stillstandszeiten.In the prior art, the guide rollers of a driven paper web are cleaned by braking the guide rollers so that the paper web moistened with cleaning agent wipes the dirt off the roller by the relative movement between the driven paper web and the slower-rotating paper guide roller. According to another known cleaning method, the paper guide roller is rotated by hand and the dirt is washed off by hand. With one method, a lot of paper is required, with the other, there are long machine downtimes.

Durch die Erfindung soll die Aufgabe gelöst werden, ein Gerät zu schaffen, mit dessen Hilfe jede Art Walzen, insbesondere im Durchmesser kleine Papierleitwalzen von Druckmaschinen schnell und einfach gereinigt werden können.The object of the invention is to provide a device by means of which any type of rollers, in particular paper guide rollers of small diameter, can be cleaned quickly and easily by printing machines.

Diese Aufgabe wird gemäß der Erfindung durch die kennzeichnenden Merkmale von Anspruch 1 gelöst.This object is achieved according to the invention by the characterizing features of claim 1.

Das Gerät 1 nach der Erfindung eignet sich insbesondere zur Reinigung einer nicht angetriebenen frei drehbaren Papierleitwalze 2, jedoch auch zur Reinigung von anderen frei drehbar gelagerten Walzen, insbesondere von Walzen, welche einen kleinen Durchmesser von nur wenigen Zentimetern haben. Allen drei Ausführungsformen des Geräts 1 ist entsprechend den Fig. 1 und 2 gemeinsam, daß in einem Gehäuse 4 des Geräts 1 eine Antriebswalze 6 drehbar gelagert ist, welche von einem Motor 8, der am Gehäuse 4 angeflanscht ist oder im Gehäuse 4 befestigt ist, angetrieben wird. Achsparallel und mit Abstand zur Antriebswalze 6 ist im Gehäuse 4 eine Bürstenwalze 10 drehbar gelagert, welche an ihrer äußeren Umfangsfläche sich radial nach außen erstreckende Borsten 12 aufweist und welche durch eine Antriebsverbindung, z.B. ein Getriebe oder einen Riementrieb 14 mit der Antriebswalze 6 antriebsmäßig verbunden ist. Auf der Bürstenwalze 10 sind zwei Stützräder 16,18 mit axialem Abstand voneinander freidrehend angeordnet. Die Stützräder 16,18 haben einen kleineren Durchmesser als ein die radial äußeren Enden der Borsten 12 einhüllender theoretischer Zylinder, so daß ein bestimmter Abschnitt einer jeden Borste 12 sich radial über die Stützräder 16,18 hinaus erstreckt. Die Bürstenwalze 10 hat die Aufgabe, von der Papierleitwalze 2 Schmutz abzubürsten. Die Stützräder 16,18 haben die Aufgabe, die Eindringtiefe der Papierleitwalze 2 in die Bürstenwalze 10 auf einen vorbestimmten Wert zu begrenzen. Die Antriebswalze 6 hat die beiden Aufgaben, die Papierleitwalze 2 durch Reibung anzutreiben und sich selbst sowie die Bürstenwalze 10 achsparallel zur Papierleitwalze 2 zu positionieren.The device 1 according to the invention is particularly suitable for cleaning a non-driven, freely rotatable paper guide roller 2, but also for cleaning other freely rotatable rollers, in particular rollers which have a small diameter of only a few centimeters. All three embodiments of the device 1, as shown in FIGS. 1 and 2, have in common that a drive roller 6 is rotatably mounted in a housing 4 of the device 1, which is driven by a motor 8 which is flanged to the housing 4 or fastened in the housing 4, is driven. Axially parallel and at a distance from the drive roller 6, a brush roller 10 is rotatably mounted in the housing 4, which has bristles 12 which extend radially outward on its outer peripheral surface and which is connected to the drive roller 6 by a drive connection, for example a gear or a belt drive 14 . On the brush roller 10, two support wheels 16, 18 are arranged freely rotating at an axial distance from one another. The support wheels 16, 18 have a smaller diameter than the radial one theoretical cylinder enveloping the outer ends of the bristles 12 so that a particular portion of each bristle 12 extends radially beyond the support wheels 16, 18. The brush roller 10 has the task of brushing dirt off the paper guide roller 2. The support wheels 16, 18 have the task of limiting the penetration depth of the paper guide roller 2 into the brush roller 10 to a predetermined value. The drive roller 6 has the two tasks of driving the paper guide roller 2 by friction and to position itself and the brush roller 10 axially parallel to the paper guide roller 2.

Das Gehäuse 4 ist an einer der Papierleitwalze 2 zugewandten Vorderseite 20 offen, wie Figur 1 zeigt. Im oder am Gehäuse 4 sind ein oder mehrere Abstreifer 22 sowie eine Flüssigkeitsauftragsvorrichtung 24, z.B. eine Sprühvorrichtung befestigt. Der Abstreifer 22 erstreckt sich über die Länge der Bürstenwalze 10 und erstreckt sich von außen nach innen zwischen die Borsten 12. Die Flüssigkeitsauftragsvorrichtung 24 besteht aus einem Sprührohr 26, einer Pumpe 28 und einem Vorrats-Behälter 30 für Reinigungsflüssigkeit. Außerdem ist im Gehäuse 4 ein entnehmbarer Auffangbehälter 32 untergebracht. Das Gehäuse 4 weist auf der von der Papierleitwalze 2 abgewandten Rückseite 34 eine Klappe 36 auf, durch die der Auffangbehälter 32 entnommen und entleert werden kann.The housing 4 is open on a front side 20 facing the paper guide roller 2, as shown in FIG. 1. In or on the housing 4 there are one or more scrapers 22 and a liquid application device 24, e.g. a sprayer attached. The scraper 22 extends over the length of the brush roller 10 and extends from the outside inwards between the bristles 12. The liquid application device 24 consists of a spray tube 26, a pump 28 and a storage container 30 for cleaning liquid. In addition, a removable collecting container 32 is accommodated in the housing 4. The housing 4 has, on the rear side 34 facing away from the paper guide roller 2, a flap 36 through which the collecting container 32 can be removed and emptied.

Vor dem Einschalten des Motors 8 wird das Gerät 1 zunächst bei stillstehendem Motor mit der offenen Vorderseite 20 an die Papierleitwalze 2 so angedrückt, daß die Umfangsfläche der Antriebswalze 6, die Borsten 12 der Bürstenwalze 10 und die Laufflächen der beiden Stützräder 16,18 der Bürstenwalze 10 an der Umfangsfläche der Papierleitwalze 2 anliegen. Bei der Antriebswalze 6 und den Stützrädern 16,18 ergibt sich eine Berührung mit der Papierleitwalze 2 in Form einer Linie. Bei der Bürstenwalze 10 werden die elastischen Borsten 12 im Kontaktbereich mit der Papierleitwalze 2 gekrümmt und zur Seite gedrängt, da die Borsten 12 radial über die Stützräder 16,18 hinausragen.Before switching on the motor 8, the device 1 is first pressed with the open front 20 to the paper guide roller 2 so that the peripheral surface of the drive roller 6, the bristles 12 of the brush roller 10 and the running surfaces of the two support wheels 16, 18 of the brush roller with the engine stopped 10 rest on the peripheral surface of the paper guide roller 2. With the drive roller 6 and the support wheels 16, 18 result in contact with the paper guide roller 2 in the form of a line. In the brush roller 10, the elastic bristles 12 are curved in the contact area with the paper guide roller 2 and pushed to the side, since the bristles 12 protrude radially beyond the support wheels 16, 18.

Die Antriebswalze 6 und die Bürstenwalze 10 umgreifen die Papierleitwalze 2 teilweise, wie Fig.1 zeigt, so daß das Gerät 1 an der Papierleitwalze 2 achsparallel ausgerichtet und quer zu ihr fixiert wird. Die Führung des Geräts 1 an der Papierleitwalze 2 ist umso besser, desto größer der Abstand der beiden achsparallelen Geräte-Walzen 6,10 voneinander ist. Eine Grenze für den Abstand zwischen den Geräte-Walzen 6,10 ist allerdings durch den Durchmesser der Papierleitwalze 2 gegeben.The drive roller 6 and the brush roller 10 partially encompass the paper guide roller 2, as shown in FIG. 1, so that the device 1 on the paper guide roller 2 is aligned axially parallel and fixed transversely to it. The guidance of the device 1 on the paper guide roller 2 is the better, the greater the distance between the two axially parallel device rollers 6, 10. A limit for the distance between the device rollers 6, 10 is, however, given by the diameter of the paper guide roller 2.

Nachdem das Gerät 1 an die Papierleitwalze 2 in der beschriebenen Weise derart angesetzt ist, daß sich die Bürstenwalze 10 oberhalb der Antriebswalze 6 befindet, wird der Motor 8, welcher die Antriebswalze 6 treibt, eingeschaltet.After the device 1 is attached to the paper guide roller 2 in the manner described that the brush roller 10 is located above the drive roller 6, the motor 8 which drives the drive roller 6 is switched on.

Gleichzeitig wird die Flüssigkeitsauftragsvorrichtung 24 in Gang gesetzt, welche Reinigungsflüssigkeit, z.B. Lösemittel oder Wasser, mittels der Pumpe 28 aus dem Behälter 30 durch das Sprührohr 26 aus einer Auslaßöffnung 38 des Sprührohres 26 pumpt. Wie Figur 1 zeigt, befindet sich die Auslaßöffnung 38 des Sprührohres 26 mittig zwischen den Walzenenden und sie ist von oben nach unten in den sich verengenden Spalt zwischen Bürstenwalze 10 und Papierleitwalze 2 gerichtet, wodurch die Reinigungsflüssigkeit in die Kontaktzone der beiden Walzen 2,10 gesprüht oder gespült oder tropfenweise zugeführt wird und die Umfangsfläche der Papierleitwalze 2 und die Borsten 12 der Bürstenwalze 10 benetzt. Da der sich von oben nach unten verengende Spalt für die Reinigungsflüssigkeit ein Abfließhindernis darstellt, verteilt sich die Reinigungsflüssigkeit vom Sprühbereich weg in Walzen-Axialrichtung nach außen, wodurch es zu einer gleichmäßigen Verteilung auf den Borsten 12 der Bürstenwalze 10 und der Papierleitwalze 2 kommt.At the same time, the liquid application device 24 is started, which pumps cleaning liquid, for example solvent or water, from the container 30 by means of the pump 28 through the spray tube 26 from an outlet opening 38 of the spray tube 26. As FIG. 1 shows, the outlet opening 38 of the spray tube 26 is located centrally between the roller ends and is directed from top to bottom into the narrowing gap between the brush roller 10 and the paper guide roller 2, as a result of which the cleaning liquid is sprayed into the contact zone of the two rollers 2, 10 or rinsed or drop by drop is supplied and the peripheral surface of the paper guide roller 2 and the bristles 12 of the brush roller 10 wetted. Since the gap narrowing from top to bottom for the cleaning liquid is an obstacle to drainage, the cleaning liquid is distributed outward from the spray area in the roller axial direction, which results in a uniform distribution on the bristles 12 of the brush roller 10 and the paper guide roller 2.

Die Drehbewegungen der Antriebswalze 6 werden mit Hilfe der Antriebsverbindung 14 auf die Bürstenwalze 10 übertragen. Bei den vorliegenden drei Ausführungsformen wird ein gekreuztes Riemengetriebe 14 verwendet, so daß die Drehrichtungen der Antriebswalze 6 und der Bürstenwalze 10 gegensinnig sind. Durch die Reibung, die durch das Andrücken der angetriebenen Antriebswalze 6 an die Papierleitwalze 2 entlang der Berührungslinie entsteht, wird die Drehbewegung der vom Motor 8 angetriebenen Antriebswalze 6 auf die Papierleitwalze 2 übertragen, wodurch sich diese gegensinnig zur Antriebswalze 6 dreht.The rotary movements of the drive roller 6 are transmitted to the brush roller 10 with the aid of the drive connection 14. In the present three embodiments, a crossed belt gear 14 is used so that the directions of rotation of the drive roller 6 and the brush roller 10 are in opposite directions. Due to the friction caused by pressing the driven drive roller 6 against the paper guide roller 2 along the line of contact, the rotational movement of the drive roller 6 driven by the motor 8 is transmitted to the paper guide roller 2, whereby the latter rotates in the opposite direction to the drive roller 6.

Die Bürstenwalze 10 dreht sich infolge der Drehrichtungsumkehr durch das gekreuzte Riemengetriebe 14 ebenfalls gegensinnig bezüglich der Andrückwalze 6 und damit gleichsinnig mit der Papierleitwalze 2. Wegen der Gleichsinnigkeit der Drehbewegungen der Bürstenwalze 10 und der Papierleitwalze 2 sind die Umfangsbewegungen der beiden Walzen 2,10 im Bereich ihrer Kontaktfläche entgegengesetzt gerichtet, wodurch eine Relativbewegung zwischen den beiden Walzen 2,10 hervorgerufen wird, wie Figur 1 zeigt. Durch die entgegengesetzte Bewegung an der Kontaktfläche ist der Abbürsteffekt besonders groß. Die Borsten 12 der Bürstenwalze 10 werden an der flächigen Kontaktzone mit der Papierleitwalze 2 entgegen der Umfangsbewegungsrichtung der Bürstenwalze 10 nach hinten gebogen und federn nach Verlassen der Kontaktzone nach vorne, wodurch die von den Borsten 12 aufgenommene Reinigungsflüssigkeit zusammen mit gelöstem Schmutz von der Papierleitwalze 2 in Umfangsbewegungsrichtung der Bürstenwalze 10 abgeschleudert wird. Der Auffangbehälter 32 ist im Flug- und Fallweg des Schmutzes im Gehäuse 4 angeordnet, so daß der in Umfangsbewegungsrichtung der Bürstenwalze 10 abgebürstete Schmutz vom Auffangbehälter 32 aufgefangen wird. Der Restschmutz wird von den Borsten 12 der Bürstenwalze 10 durch den Abstreifer 22 abgestreift. Der Abstreifer 22 ist über dem Auffangbehälter 32 angebracht, so daß der abgestreifte Schmutz in den Auffangbehälter 32 fallen kann, wie Fig.1 zeigt. Nach einiger Betriebszeit wird der Auffangbehälter 32 durch die geöffnete Klappe 36 entnommen und geleert.The brush roller 10 rotates due to the reversal of the direction of rotation by the crossed belt gear 14 also in the opposite direction with respect to the pressure roller 6 and thus in the same direction with the paper guide roller 2. Because the rotational movements of the brush roller 10 and the paper guide roller 2 are in the same direction, the circumferential movements of the two rollers 2, 10 are in the region their contact surface directed opposite, which causes a relative movement between the two rollers 2, 10, as shown in Figure 1. The brushing effect is particularly great due to the opposite movement on the contact surface. The bristles 12 of the brush roller 10 are on the flat Contact zone with the paper guide roller 2 against the circumferential direction of movement of the brush roller 10 bent back and spring forward after leaving the contact zone, whereby the cleaning liquid absorbed by the bristles 12 is thrown together with dissolved dirt from the paper guide roller 2 in the circumferential direction of movement of the brush roller 10. The collecting container 32 is arranged in the flight and fall path of the dirt in the housing 4, so that the dirt brushed in the circumferential direction of movement of the brush roller 10 is collected by the collecting container 32. The residual dirt is stripped from the bristles 12 of the brush roller 10 by the scraper 22. The scraper 22 is attached above the collecting container 32, so that the stripped dirt can fall into the collecting container 32, as shown in FIG. After some operating time, the collecting container 32 is removed and emptied through the opened flap 36.

Durch die ständige Benetzung und Spülung der drei Walzen 2,6,10 mit Reinigungsflüssigkeit wird eine gute Schmutzablösung erzielt. Anstatt einer einzigen Auslaßöffnung 38 könnte das Sprührohr 26 auch mehrere auf die Länge der Walzen 2,6,10 verteilte Auslaßöffnungen 38 aufweisen, wobei ein Teil des Sprührohres 26 dann parallel zu den Walzen angeordnet ist.The permanent wetting and rinsing of the three rollers 2, 6, 10 with cleaning fluid ensures good dirt removal. Instead of a single outlet opening 38, the spray tube 26 could also have a plurality of outlet openings 38 distributed over the length of the rollers 2, 6, 10, a part of the spray tube 26 then being arranged parallel to the rollers.

Damit mit dem Gerät 1 neben nicht angetriebenen frei drehbaren Walzen 2 auch angetriebene Walzen gereinigt werden können, muß die Verbindung zwischen dem Motor 8 und der Andrückwalze 6 lösbar sein. Dazu ist die Andrückwalze 6 mit dem Motor 8 durch eine Kupplung 40 verbunden, so daß die Andrückwalze 6 relativ zum Motor 8 in beiden Richtungen frei drehbar und von diesem vollständig entkoppelt ist, wenn die Kupplung 40 geöffnet ist. Vor Inbetriebnahme wird das Gerät 1 zunächst in der beschriebenen Weise an die stillstehende Papierleitwalze 2 angesetzt. Danach wird der Antrieb der Papierleitwalze 2 eingeschaltet, wodurch sich die Papierleitwalze 2 dreht und durch Reibung die Andrückwalze 6 antreibt, welche ihre Bewegung wiederum durch das Riemengetriebe 14 auf die Bürstenwalze 10 überträgt, so daß diese die Papierwalze 2 abbürstet.So that the device 1 can be cleaned in addition to non-driven freely rotatable rollers 2 driven rollers, the connection between the motor 8 and the pressure roller 6 must be releasable. For this purpose, the pressure roller 6 is connected to the motor 8 by a clutch 40, so that the pressure roller 6 can rotate freely in both directions relative to the motor 8 and is completely decoupled from the latter when the clutch 40 is opened is. Before starting up, the device 1 is first attached to the stationary paper guide roller 2 in the manner described. Then the drive of the paper guide roller 2 is switched on, whereby the paper guide roller 2 rotates and drives the pressure roller 6 by friction, which in turn transmits its movement through the belt transmission 14 to the brush roller 10, so that the brushes the paper roller 2.

Da das Gerät 1 in der Regel kürzer ist als die zu reinigende Papierwalze 2, muß das Gerät an der Papierleitwalze 2 entlanggeführt werden, um diese vollständig zu reinigen. Die drei Ausführungsformen der Erfindung unterscheiden sich in der Art und Weise, wie das Gerät 1 an die Papierleitwalze 2 angesetzt und an ihr entlanggeführt wird.Since the device 1 is generally shorter than the paper roll 2 to be cleaned, the device must be guided along the paper guide roll 2 in order to clean it completely. The three embodiments of the invention differ in the manner in which the device 1 is attached to the paper guide roller 2 and guided along it.

Bei der ersten Ausführungsform der Erfindung sind am Gehäuse 4 zwei Handgriffe 42,44 befestigt, mit denen das Gerät 1 gehalten und durch Körperkraft an die Umfangsfläche der Papierleitwalze 2 angedrückt und seitlich an ihr entlanggeführt wird, wie dies in Fig.1 und 2 zu sehen ist.In the first embodiment of the invention, two handles 42, 44 are attached to the housing 4, with which the device 1 is held and pressed by physical force onto the peripheral surface of the paper guide roller 2 and guided laterally along it, as can be seen in FIGS. 1 and 2 is.

Im einen Griff 42 ist ein Schalter 43 zum Einschalten des Motors 8 untergebracht, so daß er mit den Fingern der Bedienungsperson betätigt werden kann. Die Pumpe 28 ist vorzugsweise eine handbetätigte Pumpe, deren Pumpbewegungen von der Bedienungsperson an einem Handhebel 45 erzeugt werden, der am anderen Griff 44 vorgesehen ist. Wenn die Pumpe 28 eine Elektromotor-Pumpe ist, wird mit dem Handhebel 45 deren Elektromotor geschaltet. Der Flüssigkeitsbehälter 30 kann in diesem anderen Griff 44 untergebracht sein.In a handle 42 is a switch 43 for turning on the motor 8, so that it can be operated with the operator's fingers. The pump 28 is preferably a hand-operated pump, the pump movements of which are generated by the operator on a hand lever 45 which is provided on the other handle 44. If the pump 28 is an electric motor pump, the electric motor is switched with the hand lever 45. The liquid container 30 can be accommodated in this other handle 44.

Bei der zweiten Ausführungsform der Erfindung ist das Gerät 1 der ersten Ausführungsform auf einem höhenverstellbaren Geräte-Träger 46 befestigt, in der bevorzugten Ausführungsform ein Wagen mit Rädern 48, wie dies Fig.3 zeigt. Die Räder 48 sind an gegenüber dem Wagen 46 frei drehbaren Schräglenkern 52 drehbar befestigt, so daß die Schräglenker 52 mit den Rädern 48 bei Bewegung des Wagens 46 automatisch in die jeweilige Bewegungsrichtung ausgerichtet werden. Im Reinigungsbetrieb wird das Gerät 1 mit dem Wagen 46 mit Hilfe der Handgriffe 42,44 an die Papierleitwalze 2 herangeschoben und der Wagen 46 auf eine solche Höhe eingestellt, daß die Antriebswalze 6 und die Bürstenwalze 10 an der zu reinigenden Papierleitwalze 2 anliegen. Danach wird der Motor 8 eingeschaltet und das Gerät 1 mit dem Wagen 46 längs der zu reinigenden Papierwalze 2 entlanggeführt.In the second embodiment of the invention, the device 1 of the first embodiment is fastened on a height-adjustable device carrier 46, in the preferred embodiment a trolley with wheels 48, as shown in FIG. The wheels 48 are rotatably mounted on semi-trailing arms 52 which are freely rotatable relative to the carriage 46, so that the semi-trailing arms 52 are automatically aligned with the wheels 48 when the carriage 46 moves in the respective direction of movement. In cleaning operation, the device 1 with the carriage 46 is pushed by means of the handles 42, 44 to the paper guide roller 2 and the carriage 46 is set to such a height that the drive roller 6 and the brush roller 10 rest against the paper guide roller 2 to be cleaned. Then the motor 8 is switched on and the device 1 is guided along with the carriage 46 along the paper roll 2 to be cleaned.

Anstatt eines Wagens kann der Geräte-Träger 46 aber auch eine Laufkatze sein, die schienengeführt an einer Wand oder an einer Decke einer Halle oder eines Gebäudes fahrbar ist. Dieser schienengeführte Geräte-Träger 46 kann in Längs- und Querrichtung einstell- und klemmbare Schlitten aufweisen. Im Betrieb können die Schlitten so eingestellt und geklemmt werden, daß die Antriebswalze 6 und die Bürstenwalze 10 unter Vorspannung an der Papierleitwalze 2 anliegen und sich der Geräte-Träger 46 gegen diese Vorspannkraft in den Schienen abstützt. In diesem Fall übt der Geräte-Träger 46 die Halte- und Andrückkräfte auf das Gerät aus.Instead of a carriage, the device carrier 46 can also be a trolley which can be guided on a wall or on a ceiling of a hall or a building on rails. This rail-guided device carrier 46 can have adjustable and clampable slides in the longitudinal and transverse directions. In operation, the carriage can be adjusted and clamped so that the drive roller 6 and the brush roller 10 bear against the paper guide roller 2 under pretension and the device carrier 46 is supported against this pretensioning force in the rails. In this case, the device carrier 46 exerts the holding and pressing forces on the device.

Figur 4 zeigt die dritte Ausführungsform der Erfindung, bei welcher das Gerät 1 auf die Papierleitwalze 2 gehängt und durch diese getragen wird. Dabei ist das Gehäuse 4 des Geräts 1 C-förmig und es umgreift die Papierleitwalze 2. Die beiden im Gehäuse 4 gelagerten Antriebswalze 6 und Bürstenwalze 10 liegen von oben auf der Papierleitwalze 2 und werden durch ihr eigenes und das Gewicht des gesamten Geräts 1 auf die Papierleitwalze 2 gedrückt und an ihr gehalten. Um die Andrückkraft zu erhöhen und um das Gerät 1 auf der Papierleitwalze 2 auszubalancieren, ist ein Ausgleichs-Gewicht 54 unterhalb der Papierleitwalze 2 an einem Bügel 56 des Geräts 1 befestigt, der sich vom Gehäuse 4 bis unter die Papierleitwalze 2 erstreckt. Im Reinigungsbetrieb wird das Gerät 1 an den beiden Handgriffen 42,44 gehalten und an der Papierleitwalze 2 entlanggeführt. An dem Bügel 56 kann anstelle des Ausgleichs-Gewichts 54 der Vorrats-Behälter 30 für die Reinigungsflüssigkeit angeordnet werden und als Ausgleichsgewicht wirken.FIG. 4 shows the third embodiment of the invention, in which the device 1 is hung on the paper guide roller 2 and is carried by it. The housing 4 of the device 1 is C-shaped and it encompasses the paper guide roller 2. The two drive rollers 6 and brush roller 10 mounted in the housing 4 lie on the paper guide roller 2 from above and are caused by their own weight and the weight of the entire device 1 Paper guide roller 2 pressed and held on it. In order to increase the pressing force and to balance the device 1 on the paper guide roller 2, a counterweight 54 is attached below the paper guide roller 2 to a bracket 56 of the device 1, which extends from the housing 4 to below the paper guide roller 2. In cleaning operation, the device 1 is held by the two handles 42, 44 and guided along the paper guide roller 2. Instead of the balance weight 54, the reservoir 30 for the cleaning liquid can be arranged on the bracket 56 and act as a balance weight.
