Description

Die Erfindung betrifft eine Reinigungsvorrichtung gemäß dem Oberbegriff von Anspruch 1 und ein Verfahren zum Reinigen von Walzen nach Anspruch 10.The invention relates to a cleaning device according to the preamble of claim 1 and a method for cleaning rolls according to claim 10.

Stand der TechnikState of the art

Gattungsgemäße Vorrichtungen zum Pressen und Transportieren von Bogen aus Papier, Pappe und dergleichen, wie z. B. Prospekte, Zeitschriften, Flyer, dienen dazu, die Produkte so zu pressen, dass diese für den Weitertransport mit einer hohen Packungsdichte aufeinander gestapelt werden können, da durch das Pressen kompakte und gleichmäßige Stapel möglich sind.Generic devices for pressing and transporting sheets of paper, cardboard and the like, such. As brochures, magazines, flyers, serve to press the products so that they can be stacked on each other for further transport with a high packing density, as compact and uniform stacks are possible by the pressing.

Insbesondere bei gefalzten Druckweiterverarbeitungsprodukten wird zwischen den Seiten Luft eingeschlossen. Diese Luft wird durch das Pressen der Produkte herausgepresst. Weiter werden durch das Pressen bereits gebrochene, aber noch nicht vollständig gefalzte Falzkanten sauber gefalzt, was insbesondere bei dicken und steifen Materialien die Qualität der Falzkante erhöht.Especially with folded print finishing products, air is trapped between the sides. This air is squeezed out by pressing the products. Further, by pressing already broken, but not yet fully folded folded edges are neatly folded, which increases the quality of the folded edge, especially for thick and stiff materials.

Während des Betriebs einer Vorrichtung zum Pressen werden die Presswalzen durch den Kontakt mit den flächigen Druckereierzeugnissen oder Druckweiterverarbeitungsprodukten verschmutzt: Farbe von druckfrischen Produkten, Leim von Klebevorgängen und bei vorhergehendem Schneiden, Falzen, Perforieren entstandener Papierstaub setzen sich auf der Oberfläche der Presswalzen ab. Um eine Verschmutzung der zu pressenden Produkte zu vermeiden, müssen die Presswalzen regelmäßig gesäubert werden. Nach dem Stand der Technik geschieht dies durch zwei unterschiedliche Methoden:During operation of an apparatus for pressing, the press rolls are contaminated by contact with the sheet printed products or postpress products: color of fresh products, glue sticking, and paper dust formed on previous cutting, folding, perforating settle on the surface of the press rolls. To avoid contamination of the products to be pressed, the press rolls must be cleaned regularly. In the state of the art, this is done by two different methods:

Zum einen ist es bekannt, an die Presswalzen Rakeln anzustellen, um so gröbere Verschmutzungen, wie z. B. Papierstaub und Leimreste von der Presswalze zu entfernen. Problematisch dabei ist jedoch, dass feinere Verschmutzungen und insbesondere Farbablagerungen nicht entfernt werden können.On the one hand, it is known to employ squeegees on the press rollers in order to remove coarser dirt, such as dirt. B. to remove paper dust and glue residue from the press roll. The problem with this is, however, that finer contamination and especially color deposits can not be removed.

Zum zweiten geschieht die Reinigung der Presswalzen manuell, wobei die Zugänglichkeit der Presswalzen garantiert sein muss. Die DE 103 48 900 B4 beschreibt beispielsweise eine Vorrichtung zum Pressen von flächigen Druckerzeugnissen mit zwei Presswalzenpaaren, wobei die Presswalzen je eines Presswalzenpaars pneumatisch geöffnet werden können, und die voneinander beabstandeten Presswalzen eine gute Zugänglichkeit für die manuelle Reinigung bieten. Nachteilig an dieser Lösung ist, dass die Reinigung manuell geschehen muss und dass zur Reinigung der gesamten Oberfläche einer Presswalze die Walze wechselweise gereinigt und weitergedreht werden muss.Secondly, the cleaning of the press rolls is done manually, whereby the accessibility of the press rolls must be guaranteed. The DE 103 48 900 B4 describes, for example, a device for pressing sheet-like printed products with two pairs of press rolls, wherein the press rolls of each pair of press rolls can be pneumatically opened, and the spaced-apart press rolls provide good accessibility for manual cleaning. A disadvantage of this solution is that the cleaning must be done manually and that to clean the entire surface of a press roller, the roller must be cleaned alternately and further rotated.

Auch bei Druckmaschinen und im Bereich von Maschinen der Druckweiterverarbeitung besteht die Aufgabe, Bogentransportsysteme, wie z. B. Bänder und Walzen zu reinigen. Die DE 44 33 069 A1 beschreibt ein Reinigungsmedium und ein Verfahren für die Reinigung eines Bogen- bzw. Bahnenführungswegs. Dabei ist das Reinigungsmedium als eine Art Reinigungstuch ausgebildet, welches die Maschine durchläuft und aufgrund seiner Saugstruktur dabei Schmutzpartikel aufnimmt.
Die DE 196 27 748 B4 zeigt eine ähnlich wirkende Reinigungseinrichtung zur Reinigung einer Mantelfläche eines Zylinders oder einer Walze in einer Druckmaschine. Dabei wird ein Reinigungstuch von einer Vorratsrolle entnommen, mittels einer Andrückleiste an der Mantelfläche des zu reinigenden Zylinders oder der Walze angedrückt und vorbeigeführt, wobei die unregelmäßige Oberflächenstruktur des Reinigungstuchs den Schmutz aufnimmt, die Reinigungskraft des Reinigungstuchs also hauptsächlich durch die Mikrofaserstruktur gegeben ist.Even with printing presses and in the field of machines of print finishing, the task of sheet transport systems, such. B. belts and rollers to clean. The DE 44 33 069 A1 describes a cleaning medium and method for cleaning a sheet guide path. In this case, the cleaning medium is formed as a kind of cleaning cloth, which passes through the machine and thereby absorbs dirt particles due to its suction structure.
The DE 196 27 748 B4 shows a similarly acting cleaning device for cleaning a lateral surface of a cylinder or a roller in a printing press. In this case, a cleaning cloth is removed from a supply roll, pressed by means of a pressure strip on the lateral surface of the cylinder or roller to be cleaned and passed, the irregular surface structure of the cleaning cloth absorbs the dirt, the cleaning power of the cleaning cloth is thus given mainly by the microfiber structure.

Nachteilig an diesen beiden Lösungen ist, dass der Transport des Reinigungstuchs durch die Maschine kompliziert und teuer in der Realisierung ist. Auch die Maschinenparameter müssten für den Durchlauf des Reinigungstuchs angepasst werden.A disadvantage of these two solutions is that the transport of the cleaning cloth by the machine is complicated and expensive to implement. Also, the machine parameters would have to be adjusted for the passage of the cleaning cloth.

Zur Reinigung von Bandleitungen eines Falzapparats beschreibt die DE 197 25 505 A1 eine Reinigungsvorrichtung, welche mittels pneumatischen Zylindern an die Bandleitungen herangeschwenkt werden kann. Die Reinigungsvorrichtung besitzt ein auf einem schwenkbaren Lagerhebel angeordnetes Reinigungstuch, welches die Verschmutzungen aufnimmt. Neben Bandleitungen können mit dieser Reinigungsvorrichtung auch Zugwalzen gesäubert werden. Dabei wird die Reinigungsvorrichtung in bestimmten Zeitintervallen oder kontinuierlich gegen die Bandleitungen bzw. gegen die Zugwalzen gedrückt. Das Anstellen der Reinigungsvorrichtung kann dabei entweder automatisiert oder manuell erfolgen. Um eine hohe Schmutzaufnahme des Reinigungstuchs zu gewährleisten, lässt sich das Reinigungstuch mittels Rollen weiterdrehen. Die Reinigung kann zusätzlich durch Aufbringen von Reinigungsflüssigkeit unterstützt werden, welche unmittelbar auf die Bandleitungen bzw. die Zugwalzen gesprüht wird oder die auf das Reinigungstuch aufgebracht wird.
Diese Lösung erfordert einen hohen konstruktiven Aufwand, insbesondere auch in der Integration der Reinigungsvorrichtung in einen Falzapparat oder eine andere Bogen bearbeitende Maschine.For cleaning strip lines of a folder describes the DE 197 25 505 A1 a cleaning device which can be pivoted by means of pneumatic cylinders to the tape lines. The cleaning device has a arranged on a pivotable bearing lever cleaning cloth, which the Picks up dirt. In addition to strip lines, draw rolls can also be cleaned with this cleaning device. The cleaning device is pressed at certain time intervals or continuously against the ribbon cables or against the draw rollers. The hiring of the cleaning device can either be automated or manual. To ensure a high dirt absorption of the cleaning cloth, the cleaning cloth can be further rotated by means of rollers. The cleaning can be further assisted by applying cleaning liquid, which is sprayed directly onto the tape lines or the draw rolls or which is applied to the cleaning cloth.
This solution requires a high design effort, especially in the integration of the cleaning device in a folder or other sheet-processing machine.

Die EP 1 106 355 A1 zeigt eine Vorrichtung zum Reinigen von Zylindern einer Druckmaschine. Dabei werden bürstenartige Waschwalzen an einen zu reinigenden Zylinder angestellt, eine Waschflüssigkeit auf die Waschwalze und / oder auf den zu reinigenden Druckzylinder aufgebracht und Waschwalze und Druckzylinder angetrieben. Jedem Druckzylinder muss dabei eine eigene Waschwalze zugeordnet sein. Nachteilig an dieser Lösung ist, dass jeder zu reinigenden Walze eine Waschwalze zuzuordnen ist. Dichtungsmaßnahmen gegen Spritzen der Reinigungsbürsten und eine Vorrichtung zur Regelung des internen Reinigungsmittelhaushalts sowie der Antrieb der Waschwalzen erfordern viel Bauraum und verursachen hohe Fertigungskosten. Weitere Vorrichtungen sind noch aus den Druckschriften EP-A-0291745 , DE-A-10244218 und EP-A-1155862 bekannt.The EP 1 106 355 A1 shows a device for cleaning cylinders of a printing press. In this case, brush-like washing rollers are employed on a cylinder to be cleaned, a washing liquid is applied to the washing roller and / or onto the printing cylinder to be cleaned, and the washing roller and printing cylinder are driven. Each printing cylinder must be assigned its own washing roller. A disadvantage of this solution is that each roller to be cleaned is assigned to a washing roller. Sealing measures against spraying the cleaning brushes and a device for controlling the internal detergent household and the drive of the washing rollers require a lot of space and cause high manufacturing costs. Other devices are still from the publications EP-A-0291745 . DE-A-10244218 and EP-A-1155862 known.

Diese aus dem Druckmaschinenbereich und dem Bereich der Druckweiterverarbeitung bekannten Lösungen zur Reinigung lassen sich über die erwähnten Nachteile hinaus nur eingeschränkt auf die Reinigung von Presswalzen übertragen.These solutions for cleaning, which are known from the field of printing presses and the field of print finishing, can be transferred beyond the mentioned disadvantages only to a limited extent to the cleaning of press rolls.

Aufgabenstellungtask

Aufgabe der vorliegenden Erfindung ist es, eine Vorrichtung zur Reinigung von Walzen einer Vorrichtung zum Pressen und / oder Transportieren von Bogen zu schaffen, die eine einfache Reinigung mit hohem Reinigungseffekt bei einem einfachen Aufbau der Reinigungsvorrichtung mit geringen Auswirkungen auf den Aufbau der gesamten Vorrichtung zum Pressen und / oder Transportieren ermöglicht. Weiter soll ein Verfahren zur Reinigung von Walzen mit einer solchen Reinigungsvorrichtung beschrieben werden.The object of the present invention is to provide a device for cleaning rolls of a device for pressing and / or transporting sheets, which is a simple cleaning with a high cleaning effect in a simple structure of Cleaning device with little impact on the construction of the entire device for pressing and / or transporting allows. Next, a method for cleaning rolls with such a cleaning device will be described.

Diese Aufgabe wird gelöst durch eine Vorrichtung gemäß den kennzeichnenden Merkmalen von Anspruch 1 und durch ein Verfahren gemäß Anspruch 10.This object is achieved by a device according to the characterizing features of claim 1 and by a method according to claim 10.

Die Vorrichtung zum Pressen und / oder Transportieren von Bogen besitzt mindestens ein Presswalzenpaar oder ein Transportwalzenpaar und einen Walzenantrieb. Die Bogen aus Papier, Pappe und dergleichen können bedruckt oder unbedruckt sein. Üblicherweise besitzt eine derartige Vorrichtung zwei Presswalzenpaare, um ein sicheres Abpressen der Bogen zu erreichen. Wird keine Presskraft auf die Presswalzen aufgebracht, so wirken die Presswalzen als Transportwalzen. Die erfindungsgemäße Vorrichtung zur Reinigung der Walzen besitzt ein Reinigungstuch, welches über eine Zuführeinrichtung zwischen das mindestens eine Walzenpaar in die Bogentransportebene eingebracht werden kann. Die Reinigung wird durch eine Relativbewegung zwischen festem Reinigungstuch und bewegten Walzen bewirkt, wobei von dem Reinigungstuch Schmutzpartikel, insbesondere Papierstaub und Farbe, aufgenommen werden.The device for pressing and / or transporting sheets has at least one press roller pair or a pair of transport rollers and a roller drive. The sheets of paper, cardboard and the like can be printed or unprinted. Usually, such a device has two press roller pairs in order to achieve a secure pressing of the sheet. If no pressing force is applied to the press rollers, the press rollers act as transport rollers. The inventive device for cleaning the rollers has a cleaning cloth, which can be introduced via a feed device between the at least one pair of rollers in the sheet transport plane. The cleaning is effected by a relative movement between the fixed cleaning cloth and moving rollers, whereby dirt particles, in particular paper dust and paint, are picked up by the cleaning cloth.

In einer besonders vorteilhaften Ausführungsvariante der Reinigungsvorrichtung ist das Reinigungstuch auf einer Tuchrolle gelagert. In einer weiteren Ausführungsform ist die Tuchrolle mit dem Reinigungstuch auf einer Welle drehfest aufgebracht. Die Welle ist in einem Gestell gelagert, welches mit dem Maschinengestell der Vorrichtung zum Pressen und / oder Transportieren fest verbunden ist. Alternativ kann das Reinigungstuch auch direkt auf die Welle aufgerollt sein, so dass Tuchrolle und Welle eine Einheit bilden. In einer Weiterbildung der Vorrichtung zum Pressen und / oder Transportieren ist auf das eine Ende der Welle der Reinigungsvorrichtung ein Zahnrad aufgeflanscht. Am Gestell der Vorrichtung zum Reinigen der Walzen ist eine Sperrklinke drehbar angebracht. In einer ersten Lage greift die Sperrklinke in das Zahnrad ein und das Zahnrad wirkt als Sperrrad. In einer zweiten Lage gibt die Sperrklinke das Zahnrad frei und die Tuchrolle kann gedreht werden. So kann Reinigungstuch von der Tuchrolle abgerollt und zur Reinigung der Walzen in die Bogentransportebene eingebracht werden. Um das Drehen der Tuchrolle und damit das Ab- und Aufrollen des Reinigungstuchs zu erleichtern, kann auf eines der zwei Enden der Welle der Reinigungsvorrichtung eine Kurbel aufgesteckt werden.In a particularly advantageous embodiment of the cleaning device, the cleaning cloth is mounted on a cloth roll. In a further embodiment, the cloth roll with the cleaning cloth is rotatably mounted on a shaft. The shaft is mounted in a frame which is fixedly connected to the machine frame of the device for pressing and / or transporting. Alternatively, the cleaning cloth can also be rolled up directly onto the shaft, so that the cloth roll and the shaft form a unit. In a development of the device for pressing and / or transporting, a gear wheel is flanged onto one end of the shaft of the cleaning device. On the frame of the device for cleaning the rollers, a pawl is rotatably mounted. In a first position, the pawl engages the gear and the gear acts as a ratchet wheel. In a second position, the pawl releases the gear and the cloth roll can be rotated. So cleaning cloth can be unrolled from the roll of cloth and introduced to clean the rollers in the sheet transport plane. To turn the cloth roll and In order to facilitate the unwinding and rolling up of the cleaning cloth, a crank can be attached to one of the two ends of the shaft of the cleaning device.

In einer weiteren vorteilhaften Ausführungsform der Vorrichtung zur Reinigung der Walzen besitzt diese eine Einrichtung zum Kürzen des Reinigungstuches. Die Einrichtung zum Kürzen des Reinigungstuches kann beispielsweise in die Zuführeinrichtung integriert sein. Damit kann auf einfache Weise benutztes und schmutziges Reinigungstuch von dem noch auf der Tuchrolle befindlichen Reinigungstuch abgetrennt werden. Dazu besitzt die Einrichtung zum Kürzen des Reinigungstuches im einfachsten Fall eine Schneidekante, entlang derer mit einem Messer das Reinigungstuch abgetrennt wird. Alternativ kann in die Einrichtung zum Kürzen des Reinigungstuchs auch ein Messer mit bewegbarer Klinge eingebaut sein, welches manuell oder automatisch bewegt wird.In a further advantageous embodiment of the device for cleaning the rollers, this device has a device for shortening the cleaning cloth. The device for shortening the cleaning cloth can be integrated, for example, in the feeder. This can be used in a simple way used and dirty cleaning cloth separated from the still on the cloth roll cleaning cloth. For this purpose, the device for shortening the cleaning cloth in the simplest case has a cutting edge along which the cleaning cloth is cut off with a knife. Alternatively, a knife with a movable blade, which is moved manually or automatically, may also be incorporated in the device for shortening the cleaning cloth.

In einer besonders vorteilhaften alternativen Ausführungsvariante der Vorrichtung zur Reinigung der Walzen besitzt diese ein Leitblech, welches von einem Reinigungstuchzuschnitt umschlossen wird. Das Reinigungstuch liegt an der Ober- und der Unterseite des Leitblechs eng an diesem an und wird durch das Leitblech geführt. In einer Weiterbildung ist eine Zuführeinrichtung an der Vorrichtung zum Pressen und / oder Transportieren befestigt, in welche die Vorrichtung zur Reinigung der Walzen eingeschoben werden kann. Idealerweise lässt sich die Reinigungsvorrichtung in der Zuführeinrichtung in zwei verschiedenen Positionen arretieren, in einer ersten Reinigungsposition und in einer zweiten Trockenposition. Die Vorrichtung zur Reinigung der Walzen besitzt eine Einrichtung zum Klemmen des Reinigungstuchabschnitts, was einen sicheren Halt des Reinigungstuchs während des Reinigens gewährleistet und anschließend einen schnellen Wechsel des Reinigungstuches erlaubt.In a particularly advantageous alternative embodiment of the device for cleaning the rollers, this has a baffle which is enclosed by a cleaning blanket. The cleaning cloth is located on the top and bottom of the baffle closely to this and is guided by the baffle. In a development, a feeding device is attached to the device for pressing and / or transporting, in which the device for cleaning the rollers can be inserted. Ideally, the cleaning device can be locked in the feeder in two different positions, in a first cleaning position and in a second drying position. The device for cleaning the rollers has a device for clamping the cleaning cloth section, which ensures a secure hold of the cleaning cloth during cleaning and then allows a quick change of the cleaning cloth.

Besonders vorteilhaft ist es, wenn die Vorrichtung zur Reinigung der Walzen teil der Vorrichtung zum Pressen und / oder Transportieren ist.It is particularly advantageous if the device for cleaning the rollers is part of the device for pressing and / or transporting.

In einer besonders vorteilhaften Ausführungsform besitzt die Vorrichtung zum Pressen und / oder Transportieren Spritzschutzelemente, welche als Bleche ausgebildet sein können. Diese sind annähernd parallel zu den Walzen am Maschinengestell der Vorrichtung zum Pressen und / oder Transportieren befestigt. Dadurch verhindern die Spritzschutzbleche, dass während des Reinigungsprozesses Reinigungsflüssigkeit weitere Komponenten der Vorrichtung zum Pressen und / oder Transportieren, wie z. B. den Walzenantrieb oder Transportbänder, verunreinigt. Unterhalb der Walzenpaare und der Spritzschutzbleche ist eine Auffangwanne angebracht, welche am Maschinengestell der Vorrichtung zum Pressen und / oder Transportieren befestigt ist. Alternativ können auch mehrere Auffangwannen unter den jeweiligen Walzenpaaren und Spritzschutzblechen angebracht sein.In a particularly advantageous embodiment, the device for pressing and / or transporting has splash guard elements, which can be designed as sheets. These are approximately parallel to the rollers on the machine frame of the device for Fixed pressing and / or transport. As a result, prevent the splashguards, that during the cleaning process cleaning fluid other components of the device for pressing and / or transporting, such. B. the roller drive or conveyor belts, contaminated. Below the pairs of rollers and the splash guards a drip pan is attached, which is attached to the machine frame of the device for pressing and / or transporting. Alternatively, a plurality of collecting trays may be mounted under the respective roller pairs and splash guards.

Mit einer der oben beschriebenen Ausführungsformen der Reinigungsvorrichtung lassen sich die Press- und / oder Transportwalzen der Vorrichtung zum Pressen und / oder Transportieren in besonders vorteilhafter Weise reinigen. Dazu wird zur Durchführung des Reinigungsverfahrens in einem ersten Schritt Reinigungsflüssigkeit auf die zu reinigenden Walzen aufgebracht. In einem zweiten Schritt wirkt die Reinigungsflüssigkeit ein. In einem dritten Schritt wird ein Reinigungstuch in die Bogentransportebene zwischen die Walzen eingeführt. In einem vierten Schritt wird das Reinigungstuch arretiert und in einem fünften Schritt die Walzen über den Walzenantrieb angetrieben. Nach Beendigung des Reinigungsprozesses werden die Walzen angehalten und das Reinigungstuch entnommen. Anstatt die Reinigungsflüssigkeit auf die Walzen aufzubringen, kann die Reinigungsflüssigkeit alternativ auch auf das Reinigungstuch aufgebracht werden. Bevor die Vorrichtung zum Pressen und / oder Transportieren von Bogen wieder in Betrieb genommen wird, müssen die Walzen trocknen, um zu verhindern, dass bei bedruckten Bogen durch die Reinigungsflüssigkeit das Druckbild zerstört wird.With one of the embodiments of the cleaning device described above, the pressing and / or transport rollers of the device for pressing and / or transporting can be cleaned in a particularly advantageous manner. For this purpose, cleaning liquid is applied to the rollers to be cleaned in a first step to carry out the cleaning process. In a second step, the cleaning liquid acts. In a third step, a cleaning cloth is introduced into the sheet transport plane between the rollers. In a fourth step, the cleaning cloth is locked and driven in a fifth step, the rollers on the roller drive. After completion of the cleaning process, the rollers are stopped and removed the cleaning cloth. Alternatively, instead of applying the cleaning fluid to the rollers, the cleaning fluid may be applied to the cleaning cloth. Before the sheet-pressing and / or transporting apparatus is put into operation again, the rollers must be dried to prevent the printed image from being destroyed by the cleaning liquid when the sheet is printed.

In einer besonders vorteilhaften Ausführungsform des Verfahrens zum Reinigen von Walzen wird deshalb vor dem Entnehmen des Reinigungstuches ein weiterer Verfahrensschritt durchgeführt: Das Reinigungstuch wird von seiner Reinigungsposition in oder entgegen der Produkttransportrichtung in eine zweite Position, eine Trockenposition, verschoben. Anschließend werden die Walzen erneut angetrieben und die Walzen durch das Reinigungstuch getrocknet. Sobald die Walzen getrocknet sind, werden die Walzen angehalten und das Reinigungstuch entnommen.
Weiter kann das Reinigungstuch auch verschoben werden, um beispielsweise dem Verschleiß des Tuches an der Kontaktstelle mit den zu reinigenden Walzen vorzubeugen.In a particularly advantageous embodiment of the method for cleaning rolls, therefore, a further method step is carried out before the removal of the cleaning cloth. The cleaning cloth is moved from its cleaning position in or opposite to the product transport direction into a second position, a drying position. Subsequently, the rollers are driven again and the rollers dried by the cleaning cloth. Once the rollers have dried, the rollers are stopped and the cleaning cloth removed.
Further, the cleaning cloth can also be moved to prevent, for example, the wear of the cloth at the point of contact with the rollers to be cleaned.

Alternativ zum Verschieben des Reinigungstuches bei Stillstand der Walzen kann das Tuch auch während des Reinigungsprozesses bei bewegten Walzen in oder entgegen der Bogentransportrichtung verschoben werden.As an alternative to moving the cleaning cloth at standstill of the rollers, the cloth can also be moved during the cleaning process with moving rollers in or against the sheet transport direction.

Transport rollers 20 and press rollers 10 are each arranged as pairs of rollers. The contact line of a respective pair of rollers lies in the sheet transport plane E. From a second conveyor belt 21, the sheets are discharged from the apparatus for pressing and / or transporting 100. The sheet transport by conveyor belts 21 can be done either by exclusively underlying conveyor belts 21 (not shown) or lying above and below the sheet transport plane E conveyor belts 21 which guide the bow safely.

Transportwalzen 20 und Presswalzen 10 werden von einem Walzenantrieb 22 angetrieben, wobei die Kraftübertragung in Fig. 1 nicht dargestellt ist.Transport rollers 20 and press rollers 10 are driven by a roller drive 22, wherein the power transmission in Fig. 1 not shown.

Eine Reinigungsvorrichtung 200 ist am Maschinengestell 101 der Vorrichtung zum Pressen und / oder Transportieren 100 befestigt. Während dem Reinigen der Walzen 10, 20 der Vorrichtung zum Pressen und / oder Transportieren 100 wird ein Reinigungstuch 18 von der Reinigungsvorrichtung 200 über eine Zuführeinrichtung 7 zwischen die Walzen 10, 20 geführt. Das Reinigungstuch 18 ist während des Reinigungsprozesses ortsfest, während die Walzen 10, 20 angetrieben sind, was durch Pfeile angedeutet ist.A cleaning device 200 is attached to the machine frame 101 of the pressing and / or transporting device 100. During cleaning of the rollers 10, 20 of the device for pressing and / or transporting 100, a cleaning cloth 18 is guided by the cleaning device 200 via a feed device 7 between the rollers 10, 20. The cleaning cloth 18 is stationary during the cleaning process, while the rollers 10, 20 are driven, which is indicated by arrows.

Parallel zu den Walzen 10, 20 befinden sich in etwa vertikale Spritzschutzbleche 17, welche am Maschinengestell 101 der Vorrichtung zum Pressen und / oder Transportieren 100 befestigt sind. Die Spritzschutzbleche 17 verhindern, dass Reinigungsflüssigkeit auf die Transportbänder 21 gespritzt wird. Unter den Walzen 10, 20 und den Spritzschutzblechen 17 befindet sich eine Auffangwanne 16. In dieser werden vom Reinigungstuch 18 und den Walzen 10, 20 abfallende Schmutzpartikel und abtropfende Reinigungsflüssigkeit gesammelt. Die Auffangwanne 16 ist so mit dem Maschinengestell 101 der Vorrichtung zum Pressen und / oder Transportieren 100 verbunden, dass die Auffangwanne 16 einfach entnommen, geleert und gereinigt werden kann.Parallel to the rollers 10, 20 are approximately vertical splash guards 17, which are fixed to the machine frame 101 of the device for pressing and / or transport 100.

An ihrem einen Ende ist die Welle 4 mit einer Schraube 9 gesichert, an ihrem anderen Ende besitzt sie eine Handkurbel 6. Die Betätigung der Reinigungsvorrichtung 200 über die Kurbel 6 ergibt sich aus der in Fig. 2a dargestellten Seitenansicht. Am Gestell 5 der Reinigungsvorrichtung 200 ist eine drehbare Sperrklinke 3 angebracht. Diese greift in ein auf die Welle 4 aufgeflanschtes Sperrrad 2 ein. Dadurch kann verhindert werden, dass Reinigungstuch 18 ungewollt von der Tuchrolle 1 abgerollt wird. Um Reinigungstuch 18 von der Tuchrolle 1 abrollen zu können, muss die Sperrklinke außer Eingriff gebracht werden. Dazu wird sie im Uhrzeigersinn gedreht.In Fig. 2 a first embodiment of a cleaning device 200 is shown. An applied on a shaft 4 cloth roll 1 is mounted by means of two bushings 8 in a frame 5. The frame 5 is connected to the machine frame 101 of the device for pressing and / or transporting 100. At its one end, the shaft 4 is secured with a screw 9, at its other end it has a hand crank 6. The operation of the cleaning device 200 via the crank 6 results from the in Fig. 2a illustrated side view. On the frame 5 of the cleaning device 200, a rotatable pawl 3 is mounted.
