Description

Die Erfindung betrifft eine Reinigungsvorrichtung für Druck-und Druckplattenzylinder von Rotationsdruckmaschinen mit einer parallel zum Druckzylinder angeordneten Führungsschiene, an der ein längsverfahrbarer Waschapparat geführt ist, wobei der Waschapparat zumindest eine, um eine etwa achsparallel zum Druckzylinder angeordnete Rotationsachse drehantreibbare Reinigungsbürste hat.The invention relates to a cleaning device for printing and printing plate cylinder of rotary printing machines with a parallel to the printing cylinder guide rail on which a längsverfahrbarer washing apparatus is guided, wherein the washing apparatus has at least one, about an axis parallel to the printing cylinder arranged rotational axis rotatably driven cleaning brush.

Auf den Zylindern von Rotationsdruckmaschinen entstehen während des Druckvorganges Farb- und Papierstaubablagerungen, welche mit steigender Druckauflage zunehmen und ab einer gewissen Menge die Druckqualität beeinträchtigen. Um die in einer Rotationsdruckmaschine vorhandenen Druckzylinder bei Bedarf von Zeit zur Zeit reinigen zu können, hat man automatisierte Waschsysteme geschaffen, die eine rotierende Reinigungsbürste oder ein sich im Takt abwickelndes Reinigungstuch aufweisen, welche über ein Düsensprühsystem mit Waschmittel und Wasser benetzt und durch ein Anstellen an den rotierenden Druckzylinder in ihre Reinigungsposition gebracht werden.On the cylinders of rotary printing presses, ink and paper dust deposits occur during the printing process, which increase with increasing print run and, from a certain amount, impair the print quality. In order to be able to clean the printing cylinders present in a rotary printing press from time to time as required, automated washing systems have been provided which comprise a rotating cleaning brush or a cleaning cloth which cycles in cycles and which is wetted with detergent and water by means of a nozzle spraying system the rotating impression cylinder are brought into their cleaning position.

Derartige Waschsysteme sind fest dem Druckzylinder zugeordnet und werden eingesetzt, um in bestimmtem Zyklus, nach einer Anzahl von Drucken zwischen der Produktion und nach Produktionsende den Druckzylinder zu waschen. Durch dieses Waschen werden die Farb- und Papierstaubablagerungen abgewaschen. Das frisch gereinigte Gummituch des Gummituchdruckzylinders gewährleistet einen qualitativ ordnungsgemäßen Fortdruck der laufenden Druckauflage oder ordnungsgemäße Startbedingungen nach einem Auftragswechsel.Such washing systems are firmly associated with the printing cylinder and are used to wash the printing cylinder in a certain cycle, after a number of prints between the production and after the end of production. This washing rinses off the paint and paper dust deposits. The freshly cleaned blanket of the blanket impression cylinder ensures a qualitatively correct print run of the current print run or proper start conditions after a job change.

Aus der EP 1 163 115 B1 ist bereits eine, für die Druckzylinder einer Rotationsdruckmaschine bestimmte Reinigungsvorrichtung der eingangs erwähnten Art bekannt, die eine parallel zum Druckzylinder angeordnete Führungsschiene hat. Auf dieser Führungsschiene ist ein Fahrschlitten längs verfahrbar geführt, der mit einem waschapparat lösbar verbindbar ist, wobei die Führungsschiene zum Anstellen des Waschapparates an den Druckzylinder zu diesem hin verstellbar ist und wobei der Waschapparat über Versorgungsleitungen für Waschmittel, Luft und Stromversorgung mit einer Versorgungseinheit verbunden ist. Da es aus sicherheitstechnischen Gründen häufig nicht zulässig ist, in den Druckmaschinen in unmittelbarer Nähe von rotierenden Druckzylindern die Versorgungsmedien, nämlich elektrische Energie, Heißwasser und Waschmittel über lose Einzelschläuche zuzuführen, sind die Versorgungsleitungen bei der aus EP 1 163 115 B1 vorbekannten Reinigungsvorrichtung über Versorgungsleitungen innerhalb der Führungsschiene von der feststehenden Anschlussstelle zu dem Fahrschlitten geführt. Da der Waschapparat bei der vorbekannten Reinigungsvorrichtung auf dem Fahrschlitten lösbar gehalten ist, baut die in EP 1 163 115 B1 dargestellte Reinigungsvorrichtung vergleichsweise hoch. Ein derart hoher Aufbau kann jedoch unter den beengten Platzverhältnissen in Rotationsdruckmaschinen eventuell von Nachteil sein.From EP 1 163 115 B1, a cleaning device of the type mentioned for the printing cylinder of a rotary printing press is already known which has a guide rail arranged parallel to the printing cylinder. On this guide rail, a carriage is longitudinally movably guided, which is releasably connectable to a washing machine, wherein the guide rail for adjusting the washing apparatus to the pressure cylinder is adjustable towards this and the washing apparatus is connected via supply lines for detergent, air and power supply to a supply unit , Since it is often not allowed for safety reasons to supply the supply media, namely electrical energy, hot water and detergent via loose individual tubes in the printing presses in the immediate vicinity of rotating printing cylinders, the supply lines in the previously known from EP 1 163 115 B1 cleaning device via supply lines within the guide rail led from the fixed connection point to the carriage. Since the washing apparatus is detachably held on the carriage in the previously known cleaning device, the cleaning device shown in EP 1 163 115 B1 builds comparatively high. However, such a high construction may be disadvantageous under the cramped conditions in rotary printing presses.

In der EP 0 928 687 A1 ist eine Reinigungsvorrichtung für Rotationsmaschinen beschrieben, die eine parallel zum Druckzylinder angeordnete Führungsschiene hat. An dieser Führungsschiene ist ein waschapparat längs verfahrbar geführt. Der Waschapparat weist eine Reinigungsbürste auf, die um eine etwa achsparallel zum Druckzylinder angeordneten Rotationsachse drehantreibbar ist. Der Reinigungsbürste ist dazu ein Drehantrieb zugeordnet, der im Gehäuse des waschapparates achsparallel zur Reinigungsbürste hinter dieser angeordnet ist. Da die Reinigungsbürste und insbesondere der ihr zugeordnete Drehantrieb eine nicht unerhebliche Einbaugröße aufweisen, hat der vorbekannte Waschapparat im Vergleich zur Führungsschiene wesentlich größere Außenabmessungen. Wie bereits oben ausgeführt wurde, kann ein derart hoher Aufbau jedoch unter den beengten Platzverhältnissen in Rotationsdruckmaschinen eventuell von Nachteil sein.EP 0 928 687 A1 describes a cleaning device for rotary machines which has a guide rail arranged parallel to the printing cylinder. On this guide rail, a washing machine is guided longitudinally movable. The washing apparatus has a cleaning brush which is rotatably drivable about an axis of rotation approximately parallel to the printing cylinder. The cleaning brush is assigned to a rotary drive in the housing of the washing machine is arranged axially parallel to the cleaning brush behind this. Since the cleaning brush and in particular its associated rotary drive have a considerable installation size, the previously known washing apparatus compared to the guide rail has much larger external dimensions. As stated above, however, such a high construction may be disadvantageous under the confined space conditions in rotary printing presses.

Es besteht daher die Aufgabe, eine Reinigungsvorrichtung der eingangs erwähnten Art zu schaffen, die vergleichsweise kompakt und platzsparend ausgestaltet ist.It is therefore an object to provide a cleaning device of the type mentioned, which is designed comparatively compact and space-saving.

Die erfindungsgemäße Lösung dieser Aufgabe besteht bei der Reinigungsvorrichtung der eingangs erwähnten Art in den Merkmalen des geltenden Patentanspruchs 1. Bei der erfindungsgemäßen Reinigungsvorrichtung ist der der zumindest einen Reinigungsbürste zugeordnete Drehantrieb in dem durch den Bürsten-Außenumfang gebildeten Hüllkreis angeordnet. Der zur Rotation der Reinigungsbürste erforderliche Drehantrieb erfordert daher keine zusätzliche Höhe bei der Ausgestaltung der erfindungsgemäßen Reinigungsvorrichtung. Da bei der erfindungsgemäßen Reinigungsvorrichtung der Waschapparat nicht auf der Oberseite der Führungsschiene, sondern an der dem Druckzylinder zugewandten Längsseite verfahrbar gehalten ist, und da die Rotationsachse der zumindest einen Reinigungsbürste zwischen den durch Ober- und Unterseite der Führungsschiene gebildeten Ebenen angeordnet ist, wird die platzsparende Ausgestaltung der erfindungsgemäßen Reinigungsvorrichtung noch zusätzlich begünstigt. Die erfindungsgemäße Reinigungsvorrichtung weist somit auch im Bereich des Waschapparates eine derart geringe Höhe auf, dass diese Reinigungsvorrichtung auch unter beengten Platzverhältnissen im Inneren einer Rotationsdruckmaschine vorteilhaft eingesetzt werden kann.The inventive solution to this problem consists in the cleaning device of the type mentioned in the features of the valid claim 1. In the cleaning device according to the invention of the at least one cleaning brush associated rotary drive is arranged in the enveloping circle formed by the outer circumference of the brush. The rotary drive required for rotation of the cleaning brush therefore requires no additional height in the embodiment of the cleaning device according to the invention. Since in the cleaning device according to the invention, the washing apparatus is not movably held on the upper side of the guide rail, but on the longitudinal side facing the pressure cylinder, and since the axis of rotation of the at least one cleaning brush between the upper and lower sides of the guide rail is arranged, the space-saving Embodiment of the cleaning device according to the invention additionally favored. The cleaning device according to the invention thus has such a low height even in the area of the washing apparatus, that this cleaning apparatus also works in confined spaces inside a rotary printing machine can be used advantageously.

Besonders vorteilhaft ist es, wenn der Drehantrieb als ein in die zumindest eine Reinigungsbürste integrierter Elektroantrieb ausgebildet ist.It is particularly advantageous if the rotary drive is designed as an electric drive integrated in the at least one cleaning brush.

Dabei sieht eine besonders vorteilhafte Weiterbildung gemäß der Erfindung vor, dass der Drehantrieb zumindest bereichsweise innerhalb eines Reinigungsborsten tragenden Bürstenkörpers der Reinigungsbürste angeordnet ist. Bei dieser Ausführungsform ist der Drehantrieb somit im Inneren des die Reinigungsborsten tragenden Bürstenkörpers untergebracht.In this case, a particularly advantageous development according to the invention provides that the rotary drive is arranged at least partially within a brush body of the cleaning brush carrying cleaning bristles. In this embodiment, the rotary drive is thus housed inside the bristle body carrying the cleaning bristles.

Dabei ist es besonders vorteilhaft, wenn der Rotor des Drehantriebs als Bürstenkörper ausgebildet ist.It is particularly advantageous if the rotor of the rotary drive is designed as a brush body.

Stattdessen ist es aber auch möglich, dass der Büstenkörper auf einer drehantreibbaren Welle drehfest, aber in Längsrichtung verschieblich oder verfahrbar geführt ist.Instead, it is also possible that the bus body on a rotatably driven shaft rotatably, but is guided displaceably in the longitudinal direction or movable.

Weitere Merkmale der Erfindung ergeben sich aus der folgenden Beschreibung erfindungsgemäßer Ausführungsbeispiele in Verbindung mit den Ansprüchen sowie der Zeichnung. Die einzelnen Merkmale können je für sich oder zu mehreren bei einer Ausführungsform gemäß der Erfindung verwirklicht sein.Further features of the invention will become apparent from the following description of inventive embodiments in conjunction with the claims and the drawings. The individual features may be implemented individually or in combination in an embodiment according to the invention.

Fig. 4
a cleaning device comparable to Figure 1 to 3, which has a washing apparatus with a cleaning brush, which cleaning brush has a brush body which is rotationally fixed on a rotatably driven shaft, but guided in the longitudinal direction displaceable.

In den Figuren 1 bis 3 ist eine Reinigungsvorrichtung 1 dargestellt, die zur Reinigung der Druckzylinder und insbesondere der Platten- oder Gummituchzylinder in Rotationsdruckmaschinen bestimmt ist.FIGS. 1 to 3 show a cleaning device 1, which is intended for cleaning the printing cylinder and in particular the plate or blanket cylinder in rotary printing presses.

Die Reinigungsvorrichtung 1 weist eine etwa parallel zum Druckzylinder angeordnete Führungsschiene 2 auf, an der ein in Längsrichtung verfahrbarer Waschapparat 4 vorzugsweise lösbar geführt ist, der hier zumindest eine Reinigungsbürste 8 hat.The cleaning device 1 has an approximately parallel to the pressure cylinder arranged guide rail 2, on which a movable in the longitudinal direction of the washing apparatus 4 is preferably releasably guided, here at least one cleaning brush 8 has.

Wie aus Figur 3 deutlich wird, weist die Führungsschiene 2 innenseitig einen Absaugkanal auf, der zwischen den beiden Trums 5, 6 eines über Umlenkungen umlaufenden Riemens angeordnet ist. Dabei bildet ein Riementrum 5 des zum Transport des Waschapparat 4 bestimmten Riemens eine weitgehend dichte Abdeckung des an einer Längsseite offenen und durch das Schieneninnere der Führungsschiene 2 gebildeten Absaugkanals.As is clear from Figure 3, the guide rail 2 on the inside a suction channel, which is arranged between the two strands 5, 6 of a belt rotating over deflectors. In this case, a belt rim 5 of the belt intended for transporting the washing apparatus 4 forms a substantially tight covering of the suction channel which is open on one longitudinal side and formed by the rail interior of the guide rail 2.

Aus Figur 3 ist auch erkennbar, dass im Bereich des vom Waschapparats 4 ein von dort aus ins Innere des Absaugkanals führender Verbindungskanal vorgesehen ist, der hier durch zumindest einen Rohrstutzen 7 gebildet wird. Dieser Rohrstutzen 7 durchgreift eine Öffnung im benachbarten Riementrum 5 derart, dass dieser die Antriebsverbindung zwischen dem Riemen und dem Waschapparat 4 bildet.It can also be seen from FIG. 3 that, in the area of the washing apparatus 4, a connecting channel leading from there into the interior of the suction channel is provided, which is formed here by at least one pipe socket 7. This pipe socket 7 passes through an opening in the adjacent belt core 5 such that it forms the drive connection between the belt and the washing apparatus 4.

Aus den Figuren 2 und 3 wird deutlich, dass der Waschapparat 4 an der dem Druckzylinder zugewandten Längsseite der Führungsschiene 2 verfahrbar gehalten ist. Dabei ist die Rotationsachse der zumindest einen Reinigungsbürste 8 zwischen den durch Ober- und Unterseite der Führungsschiene 2 gebildeten Ebenen angeordnet. Durch diese Ausgestaltung der Reinigungsvorrichtung 1 kann diese auch unter beengten Platzverhältnissen in einer Rotationsdruckmaschine derart angebracht werden, dass ihre Reinigungsbürste 8 den zu reinigenden Druckzylinder beaufschlagt. Dabei kann die Reinigungsvorrichtung 1 derart platzsparend ausgestaltet werden, dass derartige Reinigungsvorrichtungen auch im Bereich der einander benachbarten Druckzylinder einer Rotationsdruckmaschine unterzubringen sind.From the figures 2 and 3 it is clear that the washing apparatus 4 is held on the pressure cylinder facing the longitudinal side of the guide rail 2 movable. In this case, the axis of rotation of the at least one cleaning brush 8 is arranged between the planes formed by the upper and lower sides of the guide rail 2. Due to this design of the cleaning device 1, it can also be installed in confined spaces in a rotary printing press such that its cleaning brush 8 applied to the pressure cylinder to be cleaned. In this case, the cleaning device 1 can be designed to save space such that such cleaning devices are to be accommodated in the region of the adjacent printing cylinder of a rotary printing press.

Die platzsparende Ausgestaltung der Reinigungsvorrichtung 1 wird begünstigt, wenn der der zumindest einen Reinigungsbürste 8 zugeordnete Drehantrieb 3 in dem durch den Bürsten-Außenumfang gebildeten Hüllkreis angeordnet ist. Aus einem Vergleich der Figuren 1 bis 3 ist erkennbar, dass der hier als Elektroantrieb ausgebildete Drehantrieb 3 dazu zumindest bereichsweise und hier vollständig innerhalb des die Reinigungsborsten tragenden Bürstenkörpers der Reinigungsbürste 8 angeordnet ist. Dabei ist der Rotor des Drehantriebs 3 als Bürstenkörper ausgebildet.The space-saving design of the cleaning device 1 is favored when the rotary drive 3 associated with the at least one cleaning brush 8 is arranged in the enveloping circle formed by the brush outer circumference. It can be seen from a comparison of FIGS. 1 to 3 that the rotary drive 3 embodied here as an electric drive is arranged at least partially and completely within the brush body of the cleaning brush 8 carrying the cleaning bristles. In this case, the rotor of the rotary drive 3 is designed as a brush body.

Aus Figur 1 ist zu entnehmen, dass das Gehäuse des Waschapparats 4 in der Führungsschiene 2 entlang von längsgerichteten Gleitschienen 9 verfahrbar ist. Der Waschapparat 4 erstreckt sich in Längsrichtung nämlich nur über einen Teilbereich des zu reinigenden Druckzylinders, so dass mit Hilfe des Waschapparats 4 auch einzelne auf den Druckzylindern angeordnete Seiten und Seitenteile gereinigt werden können. In den Figuren 1 und 2 ist auch der Drehantrieb 14 des zum Verfahren des Waschapparats 4 bestimmten Riemens erkennbar.From Figure 1 it can be seen that the housing of the washing apparatus 4 in the guide rail 2 along longitudinal slide rails 9 is movable. The washing apparatus 4 extends in the longitudinal direction, namely only over a portion of the pressure cylinder to be cleaned, so that with the aid of the washing apparatus 4 and individual arranged on the printing cylinders sides and side parts can be cleaned. In FIGS. 1 and 2, the rotary drive 14 of the belt intended for moving the washing apparatus 4 can also be seen.

Wie insbesondere aus Fig. 3 ersichtlich ist, ist der Waschapparat 4 und insbesondere dessen Führungsschiene 2 aus abgewinkelten Blechen gebildet, die miteinander verschraubt, vernietet oder dergleichen verbunden sind. Eine hier nicht dargestellte bevorzugte Ausführungsform sieht demgegenüber vor, dass die Führungsschiene 2 und/oder der Waschapparat aus einem Strangpressprofil und insbesondere aus einem Aluminium-Strangpressprofil hergestellt sind. Eine aus einem Strangpressprofil hergestellte Führungsschiene bietet eine hohe Eigenstabilität und reduziert den mit der Herstellung und Montage verbundenen Aufwand wesentlich.As can be seen in particular from FIG. 3, the washing apparatus 4 and in particular its guide rail 2 are formed from angled metal sheets which are screwed together, riveted or the like. A preferred embodiment, not shown here provides, in contrast, that the guide rail 2 and / or the washing apparatus from a Extruded profile and in particular made of an aluminum extruded profile. A guide rail made of an extruded profile offers a high intrinsic stability and substantially reduces the effort associated with production and assembly.

In Figur 4 ist eine Reinigungsvorrichtung 1' in schematischer Darstellung gezeigt, die mit der Reinigungsvorrichtung in den Figuren 1 bis 3 vergleichbar ist. Die Reinigungsvorrichtung 1' weist ebenfalls einen durch seine Seitenteile angedeuteten und an einem verfahrbaren, hier aber nicht dargestellten Fahrschlitten gehaltenen Waschapparat 4 mit einer Reinigungsbürste 8 auf. Diese Reinigungsbürste ist über den Fahrschlitten in Längsrichtung entlang der Führungsschiene 2 verfahrbar. Um die Reinigungsbürste 8 entlang der Führungsschiene 2 verfahren zu können, ist deren Bürstenkörper auf einer drehantreibbaren Welle 10 drehfest, aber in Längsrichtung verschieblich geführt. Die Welle 10 weist dazu eine Längsnut 11 auf, in die ein am Innenumfang des Bürstenkörpers vorstehender, hier aber nicht weiter dargestellter Gleitstein eingreift. Dabei kann die Welle 10 über einen Riemen- oder Kettenantrieb mit einem Antriebsmotor 12 in Antriebsverbindung stehen, der in Verlängerung der Führungsschiene 2 angeordnet ist. Die in Figur 4 dargestellte Ausführung, bei welcher der Fahrschlitten ebenfalls an der dem Druckzylinder zugewandten Längsseite der Führungsschiene 2 verfahrbar gehalten ist, begünstigt eine Ausgestaltung, bei der die durch die Welle 10 gebildete Rotationsachse der zumindest einen Reinigungsbürste zwischen den durch Ober- und Unterseite der Führungsschiene 2 gebildeten Ebenen angeordnet ist.FIG. 4 shows a schematic illustration of a cleaning device 1 'that is comparable to the cleaning device in FIGS. 1 to 3. The cleaning device 1 'likewise has a washing apparatus 4 with a cleaning brush 8, which is indicated by its side parts and held on a movable carriage, not shown here. This cleaning brush is movable over the carriage in the longitudinal direction along the guide rail 2. In order to be able to move the cleaning brush 8 along the guide rail 2, its brush body is rotationally fixed on a rotationally driven shaft 10, but displaceably guided in the longitudinal direction. The shaft 10 has for this purpose a longitudinal groove 11 into which engages a protruding on the inner circumference of the brush body, but not shown here sliding block. In this case, the shaft 10 via a belt or chain drive with a drive motor 12 are in drive connection, which is arranged in extension of the guide rail 2. The embodiment shown in Figure 4, in which the carriage is also movably held on the pressure cylinder facing the longitudinal side of the guide rail 2, favors a configuration in which the rotational axis formed by the shaft 10 of the at least one cleaning brush between the top and bottom of the Guide rail 2 formed levels is arranged.
