Description

Die Erfindung betrifft eine Waschvorrichtung zur wahlweisen Reinigung mehrerer Zylinder einer Bogendruckmaschine.The invention relates to a washing device for the optional cleaning of several cylinders of a sheet-fed printing machine.

Aus der DE 28 15 388 C3 ist eine Vorrichtung zum Waschen mehrerer Zylinder einer Bogendruckmaschine bekannt, bei der eine an einem Hebel gelagerte Waschwalze durch Verschwenken des Hebels wahlweise mit einem Gummizylinder oder mit einem Druckzylinder in Reinigungskontakt gebracht werden kann. Zur Reinigung der beiden Zylinder sind dabei zwei separate Antriebsmechanismen vorgesehen. Mit Wegschwenken von dem einen Zylinder wird zunächst die eine Andrucksverbindung gelöst, beim Hinschwenken zum anderen Zylinder wird die zweite Andrucksverbindung hergestellt. Die Verwendung zweier Andrücksmechanismen erfordert die Bereitstellung zweier kompletter, unabhängiger Antriebssysteme. Der Aufwand an Material, Herstellung, Montage und Wartung ist bei einer solchen Vorrichtung mit hohen Qualitätsansprüchen unerwünscht hoch.From DE 28 15 388 C3 a device for washing several cylinders of a sheet-fed printing press is known, in which a washing roller mounted on a lever can be brought into cleaning contact by pivoting the lever either with a rubber cylinder or with a printing cylinder. Two separate drive mechanisms are provided for cleaning the two cylinders. When swiveling away from the one cylinder, the first pressure connection is released, while swiveling towards the other cylinder, the second pressure connection is established. The use of two pressure mechanisms requires the provision of two complete, independent drive systems. The cost of material, manufacture, assembly and maintenance is undesirably high in such a device with high quality requirements.

Aus der EP 0 334 173 A1 ist eine Waschvorrichtung zur Reinigung mehrerer Zylinder bekannt. Darin ist beispielsweise in Figur 5 ein Verschwenken eines Andrückelements zwischen zwei zu reinigenden Zylindern vorgesehen, wobei zur Reinigung eines dritten Zylinders ein zusätzliches Andrückelement benötigt wird. Mit einer aufwendigen Steuerung des Tuchvorschubs soll dabei verhindert werden, daß das von einem Zylinder beschmutzte Tuchstück zur Reinigung des nächsten Zylinders verwendet wird.A washing device for cleaning a plurality of cylinders is known from EP 0 334 173 A1. In FIG. 5, pivoting of a pressure element between two cylinders to be cleaned is provided, for example, an additional pressure element being required for cleaning a third cylinder. An elaborate control of the cloth feed is intended to prevent the piece of cloth soiled by one cylinder from being used to clean the next cylinder.

Aus der DE 37 44 800 A1 ist eine Gummituchwaschvorrichtung bekannt, bei der ein Waschtuch mit Hilfe einer Andrückbürste in Reinigungskontakt zum Gummizylinder steht. Wischtuch und Andrückbürste sind in einem Schwenkgestell angeordnet. Nach Beendigung des Reinigungsvorganges werden das Wischtuch und die Andrückbürste durch geringfügiges Schwenken des Schwenkgestells aus der Reinigungsposition abgestellt. Vor erneuter Durchführung des Waschvorgangs wird das Schwenkgestell mit dem Wischtuch und der Andrückbürste wieder in die Reinigungsposition zurückgeschwenkt.From DE 37 44 800 A1 a blanket washing device is known in which a wash cloth is in cleaning contact with the blanket cylinder with the aid of a pressure brush. The wipe and pressure brush are arranged in a swivel frame. After the cleaning process is finished, the wiping cloth and the pressure brush are turned off by slightly swiveling the swivel frame from the cleaning position. Before the washing process is carried out again, the swivel frame with the wiping cloth and the pressure brush is swiveled back into the cleaning position.

Der vorliegenden Erfindung liegt das Problem zugrunde, eine Waschvorrichtung zur wahlweisen Reinigung mehrerer Zylinder einer Druckmaschine einfach und mit minimiertem Aufwand zu gestalten.The present invention is based on the problem of making a washing device for the optional cleaning of a plurality of cylinders of a printing press simple and with a minimum of effort.

Erfindungsgemäß wird das Problem durch eine Ausgestaltung einer Waschvorrichtung zur wahlweisen Reinigung mehrerer Zylinder einer Bogendruckmaschine gemäß den Merkmalen von Anspruch 1 gelöst. Vorteilhafte Ausgestaltungen ergeben sich aus den Unteransprüchen 2 bis 6.According to the invention, the problem is solved by an embodiment of a washing device for the optional cleaning of a plurality of cylinders of a sheet-fed printing machine in accordance with the features of claim 1. Advantageous refinements result from subclaims 2 to 6.

Durch die Verwendung nur eines gemeinsamen Andrückmittels sowie nur eines gemeinsamen Antriebmittels für den Vorschub einer Reinigungsfläche für die Reinigung mehrerer Zylinder ist eine Minimierung an Material, Produktionsaufwand, Wartungsaufwand und an Montageaufwand möglich. Die Minimierung der an jedem Zylinder zur Reinigung benötigten Mittel auf ihre einmalige Ausführung ermöglicht zudem eine raumsparende Integration der Vorrichtung in die Druckmaschine.By using only one common pressing means and only one common driving means for feeding a cleaning surface for cleaning several cylinders, a minimization of material, production effort, maintenance effort and assembly effort is possible. The minimization of the resources required for cleaning on each cylinder to their unique design also enables a space-saving integration of the device into the printing press.

Ein weiterer Vorteil liegt in der Reduzierung der aufgewendeten Mittel, sowie des Fertigungs- und Justieraufwandes für den Berührkontakt. Durch die verschwenkbare Ausbildung wird zudem der Steuerungsaufwand für den Tuchvorschub bei der Reinigung mehrerer Zylinder unter Beibehaltung einer optimalen Reinigungsqualität minimiert.Another advantage is the reduction of the resources used, as well as the manufacturing and adjustment effort for the contact. Due to the swiveling training the Control effort for the cloth feed is minimized when cleaning several cylinders while maintaining an optimal cleaning quality.

Als vorteilhaftes Merkmal gilt eine optimale Reinigung der Zylinder bei leicht herzustellender Zugänglichkeit zu den Zylindern. Die Mittel zum Verschwenken der Zylinder können gänzlich im Bereich der Maschinenseitengestelle vorgesehen werden. Da somit weder Luftschläuche noch sonstige Verschwenkelemente an der einschiebbaren Vorrichtung zur wahlweisen Reinigung mehrerer Zylinder benötigt werden, kann diese auch unter Beibehaltung der Vorteile des Ein- bzw. Herausschiebens der Waschvorrichtung einfach und kostengünstig ausgebildet werden. Gleichzeitig kann der Raum zwischen den beiden Maschinenseitengestellen von zusätzlichen raumgreifenden Elementen für die Verschwenkung freigehalten werden.An advantageous feature is an optimal cleaning of the cylinders with easy access to the cylinders. The means for pivoting the cylinders can be provided entirely in the area of the machine side frames. Since neither air hoses nor other pivoting elements are thus required on the insertable device for the optional cleaning of a plurality of cylinders, this can also be designed simply and inexpensively while maintaining the advantages of pushing the washing device in and out. At the same time, the space between the two machine side frames can be kept free of additional space-grabbing elements for pivoting.

Die erfindungsgemäße Ausbildung ermöglicht eine besonders einfache Ausbildung und Anordnung aller für eine solche Vorrichtung benötigten Antriebsmittel in einer Bogendruckmaschine. Zusätzliche Schutz- und Raumbereitstellungsmaßnahmen für die Antriebsmittel im Raum zwischen den Maschinenseitengestellen entfallen.The design according to the invention enables a particularly simple design and arrangement of all drive means required for such a device in a sheet-fed printing press. Additional protection and space provision measures for the drive means in the space between the machine side frames are not required.

Besonders vorteilhaft ist die Anordung der Befeuchtungsanlage für das Reinigungstuch. Durch die in einer Vorrichtung zur wahlweisen Reinigung mehrerer Zylinder einer Bogendruckmaschine maschinenfeste einmalige Anordnung entfällt der zu betreibende Aufwand für Zuleitung und Vorratsbehälter zur sicheren Befeuchtung für eine mitverschwenkbare Anordnung.The arrangement of the moistening system for the cleaning cloth is particularly advantageous. Due to the one-time arrangement which is fixed to the machine in a device for the optional cleaning of several cylinders of a sheet-fed printing press, there is no need to operate the supply line and storage container for reliable moistening for a pivotable arrangement.

Günstige, einfache und platzsparende Ausbildungen des Schwenk- und Vorschubmechanismuses ergeben weitere vorteilhafte Merkmale.Favorable, simple and space-saving designs of the swivel and feed mechanism result in further advantageous features.

Durch eine Ausgestaltung der erfindungsgemäßen Vorrichtung kann in einer Bogenoffsetdruckmaschine zudem eine sichere Bogenführung im Bereich des Druckzylinders mit einfachen Mitteln mit einer guten Zugänglichkeit zu den Zylindern verbunden werden.By means of an embodiment of the device according to the invention, in a sheetfed offset printing press, secure sheet guidance in the area of the printing cylinder can also be connected with simple means with good accessibility to the cylinders.

Die Erfindung ist im folgenden anhand eines Ausführungsbeispiels, dargestellt in den Figuren 1 bis 11, näher erläutert.

Eine Waschvorrichtung 1 ist zur Reinigung eines Gummituchzylinders 2, wie in Fig. 1 dargestellt, und zur Reinigung eines Druckzylinders 3 einer Bogenoffsetrotationsdruckmaschine, wie in Fig. 2 dargestellt, zwischen den Maschinenseitengestellen 29 und 30 angeordnet. Die Waschvorrichtung 1 besteht aus zwei den Maschinenseitengestellen 29 und 30 zugewandten Lagerplatten 7a und der nicht dargestellten 7b, in denen eine Saubertuchwickelrolle 4 und eine Schmutztuchwickelrolle 6 parallel zu den Zylindern 2 und 3 drehbar gelagert sind. Zwischen der Saubertuchwickelrolle 4 und der Schmutztuchwickelrolle 6 ist ein Reinigungstuch 5 gespannt. Das Reinigungstuch 5 ist über ein Andrückelement 9 geführt, das, wie in Fig. 11 dargestellt ist, aus einer Membran 40 besteht, die über einen Dichtkörper 42 gespannt ist. Im Dichtkörper 42 befindet sich eine Druckkammer 43, die mit einem nicht dargestellten Druckluftanschluß verbunden ist. Bei Betätigung der Druckluftzufuhr wird ein balliger Mittelbereich 41 der Andrückmembran 40 von der Druckkammer 43 nach außen gedrückt. Hierdurch wird, wie in den Fig. 1 und 2 mit gestrichelten Linien dargestellt ist, das Reinigungstuch 5 zur Reinigung an den entsprechenden zu reinigenden Zylinder 2 bzw. 3 angelegt. Nach Rücknahme der Druckluftzufuhr entspannt sich die Andrückmembran 40 und das Reinigungstuch 5 wird wieder in bekannter Weise in die liniert dargestellte Ausgangsposition zurückgeführt.A washing device 1 is arranged between the machine side frames 29 and 30 for cleaning a blanket cylinder 2, as shown in FIG. 1, and for cleaning a printing cylinder 3 of a sheet-fed offset printing press, as shown in FIG. 2.

Das Zahnrad 38 kämmt mit einem Zahnrad 39, das auf der Achse der Schmutztuchwickelrolle 6 drehbar befestigt ist und das über eine Freilaufkupplung mit der Schmutztuchwickelrolle 6 verbunden ist.The pivot shaft 22 is, as shown in FIGS. 8 and 10, formed in its end region to a driving fork 35. In the bearing plate 7 of the washing device, a driver 36 corresponding to the shape of the driver fork 35 is rotatably mounted. A gear 37 is connected in a rotationally fixed manner to the driver 36 and is in engagement with an intermediate gear 38 which is rotatably mounted in the bearing plate 7. The gearwheel 38 meshes with a gearwheel 39 which is rotatably fastened on the axis of the dirty tissue winding roller 6 and which is connected to the dirty tissue winding roller 6 via a one-way clutch.

Mit Hilfe von in den Maschinenseitengestellen 29, 30 gelagerten Arretierstiften 33, die von in den Maschinenseitengestellen befestigten Arretierantrieben 32 axial verschoben werden, können diese in Arretieröffnungen 34 in den jeweils zugeordneten Lagerplatten 7 bzw. 8 eingreifen. Die Lagerplatten 7 bzw. 8 können somit in ihren beiden Schwenkpositionen arretiert werden.With the aid of locking pins 33 mounted in the machine side frames 29, 30, which are axially displaced by locking drives 32 fastened in the machine side frames, they can engage in locking openings 34 in the respectively assigned bearing plates 7 and 8, respectively. The bearing plates 7 and 8 can thus be locked in their two pivot positions.

Die Waschvorrichtung 1 wird zur Herstellung der Arbeitsposition mit Hilfe der Lagerbolzen 44 bis 47 über die gehäusefeste Führung 12 und im Anschluß daran über die in ihre Schwenkposition zur Reinigung des Gummituchzylinders eingestellten und arretierten Führungsschienen 10 bzw. 11 eingeschoben, bis die Lagerbolzen 44 bzw. 45 mit einem Anschlag in den Führungsschienen 10 bzw. 11 zusammenwirken.The washing device 1 is inserted to produce the working position with the aid of the bearing bolts 44 to 47 via the guide 12 fixed to the housing and then via the guide rails 10 and 11 set and locked in their pivoting position for cleaning the blanket cylinder until the bearing bolts 44 and 45 cooperate with a stop in the guide rails 10 and 11.

Mittels der Bolzen 46 und 47 ist die Einrichtung durch Eingriff in die Bohrungen 49 in den Lagerplatten 7 und 8 arretierbar.By means of the bolts 46 and 47, the device can be locked by engaging in the bores 49 in the bearing plates 7 and 8.

Nach Lösen der Arretierung durch Zurückziehen des Stiftes 33 mithilfe des Arretierantriebs 32 kann die Schwenkwelle 16 und damit die Lagerplatte 8 aus ihrer Gummituchzylinderwaschstellung, wie in Fig. 3 dargestellt, in die Druckzylinderwaschstellung, wie in Fig. 4 dargestellt, verschwenkt werden. Der Verschwenkweg wird durch die beiden Anschläge 13 und 14 in den Maschinenseitengestellen begrenzt. Beim Verschwenken wird die gegenüber den Führungsschienen 10 und 11 arretierte Waschvorrichtung 1 über die Lagerplatte 7b mitverschwenkt, ebenso wird über die Waschvorrichtung 1 dadurch die Lagerplatte 7a, sowie die Lagerplatte 8 und die mit dieser fest verbundenen Lagerplatte 21 mit dem Pneumatikzylinder 25 und der Schwenkwelle 22 mitverschwenkt.After releasing the locking device by pulling back the pin 33 with the locking drive 32, the pivot shaft 16 and thus the bearing plate 8 can be pivoted from its blanket cylinder washing position, as shown in FIG. 3, into the printing cylinder washing position, as shown in FIG. 4. The pivoting path is limited by the two stops 13 and 14 in the machine side frames. When pivoting, the washing device 1, which is locked relative to the guide rails 10 and 11, is also pivoted via the bearing plate 7b, likewise the bearing plate 7a, the bearing plate 8 and the bearing plate 8 and the bearing plate 21, which is fixedly connected to the latter, with the pneumatic cylinder 25 and the pivot shaft 22 pivoted along.

Mit Hilfe einer an einer Federstange 27 geführten Druckfeder 26, die mit ihrem einen Ende an der Lagerplatte 8 angelenkt ist und sich mit ihrem anderen Ende an einem Federlager 28 im Maschinenseitengestell abstützt, ist es denkbar, ein regelrechtes Einrasten der Lagerplatte 8 und mit ihr der Waschvorrichtung 1 in die jeweils eingeschwenkte Arbeitsposition zu erreichen.With the aid of a compression spring 26 guided on a spring rod 27, which is articulated at one end to the bearing plate 8 and is supported at its other end on a spring bearing 28 in the machine side frame, it is conceivable to properly engage the bearing plate 8 and with it the To achieve washing device 1 in the pivoted-in working position.

Mit Hilfe des Pneumatikzylinders 25 kann über die Schwenkwelle 22 und die Mitnehmergabel 35, wie in den Fig. 8 bis 10 dargestellt, der Mitnehmer 36 und mit ihm das Zahnrad 37 verschwenkt werden. Über das Zwischenzahnrad 38 wird das Zahnrad 39 verdreht, wodurch die Schmutztuchwickelrolle 6 zum weiteren Aufrollen des Reinigungstuches 5 verdreht wird. Zur Sicherung gegen ein unerwünschtes Lösen der Spannung des Schmutztuchs und gegen nicht beabsichtigten Rücktransport des Schmutztuchs ist die Schmutztuchwickelrolle mit Hilfe des Freilaufs nur in eine Richtung bewegbar.With the help of the pneumatic cylinder 25, the driver 36 and with it the gear 37 can be pivoted via the pivot shaft 22 and the driving fork 35, as shown in FIGS. 8 to 10. The gear 39 is rotated via the intermediate gear 38, as a result of which the dirty-cloth winding roll 6 is rotated for further rolling up the cleaning cloth 5. To protect against unwanted loosening of the tension of the dirty cloth and against unintentional return of the dirty cloth is the Dirt winder roll can only be moved in one direction using the freewheel.

Wie in den Fig. 2 und 3 dargestellt, kann zur sicheren Bogenführung während des Bogenlaufes ein Bogenleitblech 20 an der Waschvorrichtung 1 so befestigt werden, daß es in der Ruheposition der Waschvorrichtung 1, die der Arbeitsposition zur Reinigung des Gummituchzylinders 2 entspricht, im Bereich oberhalb des Druckzylinders 3 vom Druckzylinder 3 mithilfe von Greifern geförderten Papierbogen von oben in ihrem Lauf stützt. Hierdurch kann ein Beschädigen der Papierbogen und der Waschvorrichtung 1 durch Flattereffekte vermieden werden.As shown in FIGS. 2 and 3, a sheet guide plate 20 can be attached to the washing device 1 for safe sheet guidance during sheet travel so that it is in the rest position of the washing device 1, which corresponds to the working position for cleaning the blanket cylinder 2, in the area above of the printing cylinder 3 from the printing cylinder 3 with the help of grabs conveyed paper sheets from above in their course. In this way, damage to the paper sheets and the washing device 1 by flutter effects can be avoided.

Soll die Waschvorrichtung zur Schaffung einer besseren Zugänglichkeit des Gummituchzylinders 2 oder des Druckzylinders 3 aus ihrer Position entfernt werden, so wird diese in ihrer Arbeitsposition zur Reinigung des Gummituchzylinders nach Lösen der Arretierung mit den Lagerbolzen 46 und 47 zu den Lagerplatten 8 bzw. 15 gegenüber den Führungsschienen 10 und 11 und nachdem die Mitnehmergabel 35 mit ihrer Gabelöffnung parallel zur Führungsschiene 11 ausgerichtet wurde, entlang der Führungsschienen 10, 11 und 12 in eine nicht dargestellte Warteposition zurückgezogen oder, insbesondere auch zum Wechseln des Waschtuchs, aus der Maschine entnommen.If the washing device is to be removed from its position in order to provide better access to the blanket cylinder 2 or the impression cylinder 3, it will be in its working position for cleaning the blanket cylinder after releasing the locking with the bearing bolts 46 and 47 to the bearing plates 8 and 15 opposite the Guide rails 10 and 11 and after the driving fork 35 has been aligned with its fork opening parallel to the guide rail 11, retracted along the guide rails 10, 11 and 12 into a waiting position, not shown, or, in particular for changing the washcloth, removed from the machine.

Die Position der Gabelöffnung ist vorteilhafterweise so gewählt, daß diese in der Ausgangsposition des Tuchvorschubs parallel zur Führungsschiene 11 ausgerichtet ist. Nach jedem Tuchvorschub wird die Gabelöffnung durch Zurückfahren des Pneumatikzylinderkolbens in seine Ausgangsstellung wieder in diese parallele Position gebracht. Ein Freilauf verhindert das Zurückdrehen des Tuches.The position of the fork opening is advantageously chosen so that it is aligned parallel to the guide rail 11 in the starting position of the cloth feed. After each cloth advance, the fork opening is brought back into this parallel position by moving the pneumatic cylinder piston back to its starting position. A freewheel prevents the cloth from turning back.

Wie in der Fig. 1 dargestellt, ist eine Reinigungsmittelauftragsvorrichtung 48 bekannter Bauart zwischen den Maschinenseitengestellen 29, 30 im Bereich des Gummizylinders 2 oberhalb der Waschvorrichtung 1 in Drehrichtung des Gummizylinders 2 vorgeordnet befestigt. Das Waschmittel kann jeweils in der aufgrund der höheren Verschmutzung häufiger benutzten Gummizylinderwaschposition von außen auf das Reinigungstuch in bekannter Weise aufgebracht werden.As shown in FIG. 1, a cleaning agent application device 48 is of a known type fastened between the machine side frames 29, 30 in the area of the rubber cylinder 2 above the washing device 1 in the direction of rotation of the rubber cylinder 2. The detergent can be applied to the cleaning cloth in a known manner from the outside in the rubber cylinder washing position, which is used more frequently due to the higher degree of soiling.

Weitere ballige Ausführungsformen der Druckmembran 41 sind, wie in Fig. 11b beispielhaft dargestellt, denkbar. Die ballige Ausführung ermöglicht ein schnelles, exaktes Überbrücken der Druckzylindergreifer bei Reinigung des Druckzylinders und vollständige Reinigung auch in den den Druckzylindergreifern benachbarten Bereichen des Druckzylinders.Further crowned embodiments of the pressure membrane 41 are conceivable, as shown by way of example in FIG. 11b. The spherical design enables fast, exact bridging of the impression cylinder grippers when cleaning the impression cylinder and complete cleaning even in the areas of the impression cylinder adjacent to the impression cylinder grippers.
