Abstract

To clean curved surfaces, a clean sheet roller carries unused cleaning sheets. A dirty sheet roller receives used sheets. A pressure unit brings the cleaning sheet in contact with the surface to be cleaned. Devices are provided for the withdrawal of the cleaning sheet from the clean sheet roller and its rolling onto the dirty sheet roller. The withdrawal of the cleaning sheet (5) from the clean sheet roller (4) occurs via the pressure component (8) effecting a movement which produces an effective connection between the cleaning sheet and the surface to be cleaned. The clean sheet roller is connected with the dirty sheet roller via a traction gear (23).

Die Erfindung betrifft eine Einrichtung zum Reinigen gekrümmter Flächen nach dem Tuchprinzip mit einer unbenutztes Reinigungstuch tragenden Saubertuchrolle, einer benutztes Tuch aufnehmenden Schmutztuchrolle, einem das Reinigungstuch in Wirkverbindung mit der zu reinigenden Fläche bringenden Andrückelement sowie Mitteln zum Abziehen des Reinigungstuches von der Saubertuchrolle und Aufrollen auf die Schmutztuchrolle.The invention relates to a device for cleaning curved surfaces according to the cloth principle with an unused cleaning cloth carrying a cleaning cloth roll, a used one Cloth-absorbing cloth roll, the cleaning cloth in operative connection with the pressing element to be cleaned surface and means for removing the cleaning cloth from the cleaning cloth roll and rolling onto the dirty cloth roll.

Bei derartigen Einrichtungen zum Reinigen nach dem Tuchprinzip ist es bekannt, dass das Reinigungstuch in Wirkverbindung mit dem zu reinigenden Flächen bringende Andrückelement mit einer elastischen Gummimembran zu versehen. Mittels eines die Gummimembran beaufschlagenden Druckmediums kann diese gedehnt und das Reinigungstuch an die jeweils zu reinigende Fläche geführt werden (DE 300 5469-C2).In such devices for cleaning according to the cloth principle, it is known that Cleaning cloth in operative connection with the pressing element bringing surfaces to be cleaned to be provided with an elastic rubber membrane. By means of a rubber membrane pressure medium can be stretched and the cleaning cloth attached to each surface to be cleaned are guided (DE 300 5469-C2).

Weiterhin ist es bekannt, das Andrückelement als funktionelle Einheit auszubilden und mit einer der zu reinigenden Fläche zugewandte elastischen Wulst zu versehen. Dieses Andrückelement ist mittels pneumatischer Stellmittel verschiebbar angeordnet und kann so in oder außer Eingriff mit der jeweils zu reinigenden Fläche gebracht werden.
Diese Einrichtungen zum Reinigen weisen weiterhin Mittel zum Abziehen des auf der Saubertuchrolle vorgesehenen Reinigungstuches sowie Mittel zum Aufrollen des verschmutzten Reinigungstuches auf die Schmutztuchrolle auf. Außerdem sind bei diesen Einrichtungen Mittel vorgesehen, die sichern, dass konstante Reinigungstuchabschnitte von der Saubertuchrolle abgezogen werden. Dazu wird z.B. bei der DE 300 5469 C2 der Durchmesser der Schmutztuchrolle abgetastet und über eine mechanische Steuerung der Drehwinkel der angetriebenen Schmutztuchrolle in Abhängigkeit vom Durchmesser begrenzt.Furthermore, it is known to design the pressure element as a functional unit and to provide it with an elastic bead facing the surface to be cleaned. This pressure element is displaceably arranged by means of pneumatic actuating means and can thus be brought into or out of engagement with the surface to be cleaned in each case.
These cleaning devices furthermore have means for pulling off the cleaning cloth provided on the cleaning cloth roll and means for rolling up the soiled cleaning cloth on the dirty cloth roll. In addition, means are provided in these devices which ensure that constant cleaning cloth sections are pulled off the cleaning cloth roll. For this purpose, for example in DE 300 5469 C2, the diameter of the dirty tissue roll is scanned and the angle of rotation of the driven dirty tissue roll is limited by a mechanical control depending on the diameter.

Weiterhin ist es bekannt, um gleiche Reinigungsabschnitte realisieren zu können, den Tuchrollen Winkelencoder zuzuordnen und durch Vor- und Zurückspulen den zur Reinigung zur Verfügung stehenden Tuchabschnitt konstant zu halten.
Die Mittel zum Ab- und Aufspulen des Tuches und die zur Sicherung eines konstanten Tuchabschnitts sind aufwendig in der Realisierung und beanspruchen zusätzlich Raum, der insbesondere in Druckwerken von Bogendruckmaschinen nicht zur Verfügung steht.Furthermore, it is known in order to be able to implement the same cleaning sections, to assign the cloth rolls to an angle encoder and to keep the cloth section available for cleaning constant by forwarding and rewinding.
The means for unwinding and rewinding the blanket and for securing a constant portion of the blanket are complex to implement and additionally take up space which is not available in particular in printing units of sheet-fed printing machines.

Aufgabe der Erfindung ist es, eine Einrichtung zum Reinigen gekrümmter Flächen nach dem Tuchprinzip zu schaffen, die mit einfachen Mitteln und einer einen geringen Bauraum beanspruchenden Weise zu realisieren ist. The object of the invention is to provide a device for cleaning curved surfaces after To create a cloth principle that with simple means and a small footprint Way to be realized.

Erfindungsgemäß wird die Aufgabe durch die Merkmale des Anspruchs 1 gelöst.According to the invention the object is achieved by the features of claim 1.

Durch die erfindungsgemäße Lösung wird mit einfachen Mitteln sichergestellt, dass unabhängig vom Durchmesser der Saubertuchrolle oder der Schmutztuchrolle immer gleiche Tuchabschnitte abgezogen und entsprechend der Schmutz-tuchrolle zugeführt werden. Außerdem ist durch das Abziehen des Reinigungstuches mit Hilfe des Andrückelements eine raumsparende und kostengünstige Realisierung möglich.The solution according to the invention ensures with simple means that independent of the diameter of the clean cloth roll or the dirty cloth roll always the same Cloth sections are pulled off and fed according to the dirty cloth roll. Moreover is a by pulling off the cleaning cloth with the help of the pressure element space-saving and cost-effective implementation possible.

Die Erfindung soll nachstehend an einem Ausführungsbeispiel näher erläutert werden.The invention will be explained in more detail below using an exemplary embodiment.

In der zugehörigen Zeichnung ist ein zu reinigender Zylinder 1 mit einer als funktionelle Einheit ausgebildeten Einrichtung zum Reinigen 2 in einer geschnittenen Seitendarstellung gezeigt. Die Einrichtung zum Reinigen 2 kann z.B. ein Gestell 3 aufweisen, in dem sämtliche Bauelemente angeordnet sind, so dass die Einrichtung zum Reinigen 2 in ihrer Gesamtheit aus der Maschine entnommen werden kann.
Die Einrichtung zum Reinigen 2 weist eine Saubertuchrolle 4 auf, die mit unbenutztem Reinigungstuch 5 versehen ist. Die Saubertuchrolle 4 ist drehfest mit einer Spindel 6 verbunden, die ihrerseits mit einer Zahnriemenscheibe 7 drehfest verbunden ist. Das Reinigungstuch 5 wird von der Saubertuchrolle 4 an einem Andrückelement 8 vorbei zur Schmutztuchrolle 9 geführt. Die Schmutztuchrolle 9 ist drehfest mit einer Spindel 10 verbunden, die ihrerseits über eine Rutschkupplung 22 mit einer Zahnriemenscheibe 11 verbunden ist. Der Spindel 10 ist weiterhin ein Gesperre 12 zugeordnet, welches eine Drehung der Spindel 10 und damit der Schmutztuchrolle 9 nur in Drehrichtung 13 zuläßt. Die Zahnriemenscheibe 7 und die Zahnriemenscheibe 11 sind durch einen Zahnriemen 14 verbunden. Der Zahnriemen 14 wird mit Hilfe von Führungsrollen 15, die mit der Zahnriemenscheibe 7 bzw. mit der Zahnriemenscheibe 11 korrespondieren, geführt und mittels einer Spannrolle 16, die durch einen sich gegen das Gestell 3 abstützenden Kraftspeicher 17, der im Ausführungsbeispiel als Druckfeder 18 ausgebildet ist, gespannt.
Das Andrückelement 8 besteht im Ausführungsbeispiel aus einem im Gestell 3 angeordneten Grundkörper 19, in dem sich ein Druckkörper 20 erstreckt, der durch nicht dargestellte Mittel druckbeaufschlagbar und druckentlastbar ist. Bei Druckentlastung nimmt der Druckkörper 20 die in Vollliniendarstellung gezeigte Lage ein, während bei einer Druckbeaufschlagung der Druckkörper in die gestrichelte dargestellte Position übergeht. Dabei wird der Druckkörper 20 so ausgewählt, dass die Druckfläche 21 bei einer Druckbelastung einen großen Weg zurücklegt.
Es ist aber auch möglich, das Andrückelement 8 so auszubilden, dass es im dem zu reinigenden Zylinder 1 zugewandten Bereich eine sich parallel entlang dem Zylinder 1 erstreckende elastische Zone aufweist und das Andrückelement durch Stellelemente aus einer vom Zylinder 1 entfernten Rastposition in eine Arbeitsposition, in der das Reinigungstuch 5 in Wirkverbindung mit dem Zylinder 1 steht, verbracht werden kann.In the accompanying drawing, a cylinder 1 to be cleaned is shown with a device 2 designed as a functional unit for cleaning in a sectional side view. The device for cleaning 2 can have, for example, a frame 3 in which all components are arranged, so that the device for cleaning 2 can be removed from the machine in its entirety.
The device for cleaning 2 has a clean cloth roll 4, which is provided with an unused cleaning cloth 5. The cleaning cloth roll 4 is rotatably connected to a spindle 6, which in turn is rotatably connected to a toothed belt pulley 7. The cleaning cloth 5 is guided by the cleaning cloth roll 4 past a pressure element 8 to the dirty cloth roll 9. The dirty tissue roll 9 is connected in a rotationally fixed manner to a spindle 10, which in turn is connected to a toothed belt pulley 11 via a slip clutch 22. The spindle 10 is also assigned a ratchet 12, which permits rotation of the spindle 10 and thus of the dirty tissue roller 9 only in the direction of rotation 13. The toothed belt pulley 7 and the toothed belt pulley 11 are connected by a toothed belt 14. The toothed belt 14 is guided with the aid of guide rollers 15, which correspond to the toothed belt pulley 7 or with the toothed belt pulley 11, and by means of a tensioning roller 16, which is supported by a force accumulator 17 which is supported against the frame 3 and is designed as a compression spring 18 in the exemplary embodiment , curious; excited.
In the exemplary embodiment, the pressing element 8 consists of a base body 19 arranged in the frame 3, in which extends a pressure body 20 which can be pressurized and relieved of pressure by means not shown. When the pressure is released, the pressure body 20 assumes the position shown in the full line representation, while when pressure is applied, the pressure body changes to the position shown in broken lines. The pressure body 20 is selected in such a way that the pressure surface 21 travels a long way under a pressure load.
However, it is also possible to design the pressing element 8 in such a way that it has an elastic zone extending parallel to the cylinder 1 in the area facing the cylinder 1 to be cleaned, and the pressing element by adjusting elements from a detent position distant from the cylinder 1 to a working position, in which the cleaning cloth 5 is in operative connection with the cylinder 1, can be spent.

Die Wirkungsweise der Einrichtung zum Reinigen 2 ist folgende: In einer Ruheposition ist der Druckkörper 20 druckentlastet und das Reinigungstuch 5, der Zahnriemen 14, die Spannrolle 16 sowie der Druckkörper 20 in Volllinien dargestellt.
Soll der Zylinder 1 gereinigt werden, wird der Druckkörper 20 druckbelastet und gelangt damit in die gestrichelt dargestellte Position, wobei das Reinigungstuch 5 von der Saubertuchrolle 4 abgezogen wird. Durch das Gesperre 12 wird ein Abziehen von auf der Schmutztuchrolle 9 aufgewickelten Reinigungstuch 5 verhindert. Mit dem Abziehen des Reinigungstuches 5 von der Saubertuchrolle 4 wird gleichzeitig die Zahnriemenscheibe 7 verdreht. Da die Zahnriemenscheibe 11 bedingt durch das Reinigungstuch 5 einer Drehung der treibenden Zahnriemenscheibe 7 nicht folgen kann, wird der Durchhang des Zahnriemens 14 im Leertrum vergrößert (gestrichelte Darstellung) während der Zahnriemen 14 im Lasttrum gestrafft, damit die Spannrolle 16 aus der Vollliniendarstellung in die gestrichelte Darstellung verbracht und so die Druckfeder 18 gespannt wird. Wird der Druckkörper 20, wenn z.B. der Reinigungsvorgang beendet oder ein sauberer Reinigungstuchabschnitt benötigt wird, druckentlastet, bewegt sich die Spannrolle 16 durch die Wirkung der Druckfeder 18 in die Ausgangslage zurück, wodurch die Schmutztuchrolle 9 in Drehrichtung 13 verdreht und damit das Reinigungstuch 5 auf die Schmutztuchrolle 9 aufgespult wird. Gleichzeitig wird der Durchhang des Zahnriemens 14 im Leertrum beseitigt.
Die Rutschkupplung 22 ist dabei so eingestellt, dass sie erst dann anspricht, wenn das aufzuwickelnde Reinigungstuch 5 straff gespannt ist.
Das Übersetzungsverhältnis ins Schnelle von der durch die Saubertuchrolle 4 angetriebenen Zahnriemenscheibe 7 zur die Schmutztuchrolle 9 treibenden Zahnriemenscheibe 11 ist so gewählt, dass unabhängig vom jeweiligen Verhältnis der Durchmesser der Saubertuchrolle 4 zur Schmutztuchrolle 9 immer mehr bzw. genau so viel Reinigungstuch 5 aufgewickelt werden kann, wie von der Saubertuchrolle 4 durch das Andrückelement 8 abgezogen wird. Da dadurch immer mehr Energie in der Druckfeder 18 gespeichert wird als zum Aufwickeln auf der Schmutztuchrolle 9 benötigt wird, ist sichergestellt, dass das Reinigungstuch 5 immer straff gespannt wird, wobei die Rutschkupplung 22 dann anspricht, wenn eine entsprechende Spannung im Reinigungstuch 5 vorliegt. Damit wird auch erreicht, dass nach jedem Transport des Reinigungstuches 5 ein vorgegebener Spannungszustand in der Druckfeder 18 eingestellt wird.The mode of operation of the device for cleaning 2 is as follows: in a rest position, the pressure body 20 is relieved of pressure and the cleaning cloth 5, the toothed belt 14, the tensioning roller 16 and the pressure body 20 are shown in full lines.
If the cylinder 1 is to be cleaned, the pressure body 20 is subjected to pressure and thus reaches the position shown in broken lines, the cleaning cloth 5 being pulled off the cleaning cloth roll 4. The locking mechanism 12 prevents the cleaning cloth 5 wound on the dirty cloth roll 9 from being pulled off. When the cleaning cloth 5 is pulled off the cleaning cloth roll 4, the toothed belt pulley 7 is rotated at the same time. Since the toothed belt pulley 11 cannot follow a rotation of the driving toothed belt pulley 7 due to the cleaning cloth 5, the sag of the toothed belt 14 in the empty strand is increased (dashed line) while the toothed belt 14 is tightened in the load strand so that the tensioning roller 16 moves from the full line line to the dashed line Representation spent and the compression spring 18 is tensioned. If the pressure body 20 is relieved of pressure, for example when the cleaning process is finished or a clean cleaning cloth section is required, the tensioning roller 16 moves back into the starting position due to the action of the compression spring 18, whereby the dirty tissue roller 9 rotates in the direction of rotation 13 and thus the cleaning cloth 5 onto the Dirty cloth roll 9 is wound up. At the same time, the sag of the toothed belt 14 in the empty strand is eliminated.
The slip clutch 22 is set so that it only responds when the cleaning cloth 5 to be wound is taut.
The rapid transmission ratio from the toothed belt pulley 7 driven by the cleaning cloth roller 4 to the toothed belt pulley 11 driving the dirty cloth roll 9 is selected such that, regardless of the respective ratio, the diameter of the cleaning cloth roll 4 to the dirty cloth roll 9 can be wound up with more or exactly as much cleaning cloth 5, as is pulled off the cleaning cloth roll 4 by the pressing element 8. Since this means that more and more energy is stored in the compression spring 18 than is required to wind it up on the dirty tissue roll 9, it is ensured that the cleaning tissue 5 is always stretched tight, the slip clutch 22 responding when a corresponding tension is present in the cleaning tissue 5. This also ensures that a predetermined tension state is set in the compression spring 18 after each transport of the cleaning cloth 5.

Im Ausführungsbeispiel wurde die Verbindung zwischen der Saubertuchrolle 4 und der Schmutztuchrolle 9 an Hand eines Zahnriemengetriebes dargestellt. Es ist aber auch möglich, ein beliebiges Zugmittelgetriebe 23 vorzusehen. In the embodiment, the connection between the cleaning cloth roll 4 and Dirty cloth roll 9 shown using a toothed belt gear. But it is also possible to provide any traction mechanism 23.
