Description

Die Erfindung betrifft eine Reinigungsvorrichtung zum Reinigen zumindest einer, eine Papierbahn führenden Leitwalze, welche Reinigungsvorrichtung Wenigstens eine im Bereich der zu reinigenden Leitwalze koaxial zu dieser in dem durch die Papierbahn umgrenzten Freiraum angeordnete Reinigungsbürste hat, die ein Borstenfeld mit wendelförmig umlaufenden Borsten aufweist und die zumindest während des Reinigungsvorgangs mit ihrem Borstenfeld wenigstens bereichsweise die Leitwalze reinigend beaufschlagt, wobei die Reinigungsvorrichtung mindestens einen Schmutzauslaß hat, über den die mittels der zumindest einen Reinigungsbürste von der Leitwalze entfernten Schmutzpartikel absaugbar oder dergleichen abführbar sind.The invention relates to a cleaning device for cleaning at least one guide roller leading a paper web, which cleaning device has at least one in the region of the guide roller to be cleaned coaxial with this arranged in the bounded by the paper web clearance cleaning brush having a bristle field with helically rotating bristles and at least during the cleaning process with its bristle field at least partially applied to the guide roller cleaning, the cleaning device has at least one dirt outlet through which the means of at least one cleaning brush removed from the guide roller dirt particles sucked or the like can be discharged.

In den Insbesondere zum Zeitungsdruck verwendeten Rotationsdruckmaschinen wird die Papierbahn über eine Vielzahl von Leitwalzen geführt, welche Leitwalzen zur Bahnführung sowie zur Umlenkung der Papierbahn im Maschineninneren dienen. Dabei wird das frisch bedruckte Papier über solche Leitwalzen geführt, so dass eine Teilmenge der noch frischen Druckfarbe an den betreffenden Leitwalzen haften bleiben kann. Man hat daher diesen Leitwalzen bereits eine grobe oder strukturierte Walzenoberfläche gegeben, damit die mit dem Papier oder der darauf befindlichen Druckfarbe in Kontakt kommenden Kontaktflächen an der Walzenoberfläche möglichst klein gehalten werden können. Die auf der Walzenoberfläche dennoch verbleibende Druckfarbe kann jedoch mit der Zeit zu einem unerwünschten Farbauftrag auf die nachfolgenden Partien der Papierbahn und somit zu einem gewissen Farbschleier auf dem Zeitungspapier führen.In the rotary printing machines used in particular for newspaper printing, the paper web is guided over a plurality of guide rollers, which serve guide rollers for web guidance and for deflecting the paper web inside the machine. In this case, the freshly printed paper is guided over such guide rollers, so that a subset of the still fresh ink can adhere to the respective guide rollers. Therefore, these guide rolls have already been given a coarse or structured roll surface so that the contact surfaces coming into contact with the paper or the printing ink thereon can be kept as small as possible on the roll surface. However, the still remaining on the roll surface ink can lead over time to an undesirable application of ink to the subsequent parts of the paper web and thus to a certain color fog on the newsprint.

Damit dieser Farbschleier nicht übermäßig störend in Erscheinung tritt, müssen die Leitwalzen von Zeit zur Zeit gereinigt werden. Bedenkt man, dass sich eine Vielzahl solcher Leitwalzen in einer Druckmaschine befinden, wird klar, dass eine solche Reinigung der Leitwalzen mit einem nicht unerheblichen Aufwand verbunden sein kann.To ensure that this color fog does not appear overly disturbing, the guide rollers must be cleaned from time to time. Considering that one is Variety of such guide rollers are located in a printing press, it is clear that such a cleaning of the guide rollers can be associated with a considerable effort.

Man hat daher auch eine Reinigungsvorrichtung geschaffen, bei der das Reinigen der Leitwalzen produktionsabhängig für die verschiedenen Bahnwege durch Wischen mit Hilfe der Papierbahnen erfolgt. Dazu werden die Papierbahnen vor dem Einlaufen in die Druckwerke beidseitig mit Waschmittel getränkt. Die nassen Papierbahnen werden mit niedriger Geschwindigkeit durch die Maschine gezogen. Bremseinheiten stoppen bei unterschiedlichen Umschlingungswinkeln die Leitwalzen in verschiedenen getakteten Zeiten und erzeugen dadurch den Abwischvorgang. Dabei nimmt die Papierbahn festgesetzte Farbreste und Papierstaub von den Leitwalzen auf und fördert sie aus der Maschine. Das Blockieren der Leitwalzen erfolgt bei dem bis zu mehreren Minuten dauernden Waschvorgang mehrmals, damit auch die gesamte Oberfläche der Leitwalzen gereinigt wird. Zum Trockenreiben der Leitwalzen werden diese ebenfalls mehrmals bis zum Stillstand abgebremst, während die trockene Papierbahn vorbeiläuft. Bedenkt man, dass dieser mittels einer nassen Papierbahn durchgeführte Waschvorgang über einen Zeitraum von mehreren Minuten durchzuführen ist und berücksichtigt man, dass eine leistungsfähige Druckmaschine annähernd 100 Meter Papier pro Minute durchlaufen können, wird klar, dass der mit der vorbekannten Reinigungsvorrichtung durchgeführte Waschvorgang zu einem "Abfallberg" von mehreren 100 Metern Papierabfall führen kann, wobei dieser Papierabfall mit Reinigungsmittel durchtränkt und mit überschüssiger Druckfarbe verschmutzt ist und daher an sich nur als Sonderabfall entsorgt werden sollte.It has therefore also provided a cleaning device in which the cleaning of the guide rollers production-dependent for the various web paths by wiping with the help of the paper webs. For this purpose, the paper webs are impregnated on both sides with detergent before entering the printing units. The wet paper webs are pulled through the machine at low speed. Brake units stop at different wrap angles the guide rollers in different clocked times and thereby generate the wiping process. In this case, the paper web takes fixed ink residues and paper dust from the guide rollers and conveys them out of the machine. The blocking of the guide rollers takes place several times during the washing process several times, so that the entire surface of the guide rollers is cleaned. To dry the guide rollers, these are also decelerated several times to a standstill while the dry paper web passes. Considering that this washing operation carried out by means of a wet paper web is to be carried out over a period of several minutes and taking into account that a powerful printing press can pass approximately 100 meters of paper per minute, it becomes clear that the washing process carried out with the previously known cleaning device results in a " Abfallberg "can lead from several 100 meters of paper waste, which paper waste is soaked with detergent and contaminated with excess ink and therefore should be disposed of only as hazardous waste.

Aus der DE 38 12 678 C3 ist bereits eine Reinigungsvorrichtung zum Reinigen von zylindrischen Mantelflächen in einer Bogenrotationsmaschine bekannt, die eine walzenförmige Reinigungsbürste hat, welche Reinigungsbürste in den nicht bogenführenden Bereich an die Mantelfläche des Zylinders während des Druckes anstellbar ist. Die Reinigungsbürste der aus DE 38 12 678 C3 vorbekannten Reinigungsvorrichtung, die auch ein Borstenfeld mit spiralf3rmig angeordneten Borstenreihen aufweisen kann, ist in einer Absaugglocke angeordnet, die einen, sich über die Längserstreckung der Reinigungsbürste reichenden Saugluftanschluß hat. Die vorbekannte Reinigungsvorrichtung, die bei geringen Rüstzeiten einen abschmierfreien Bogentransport mit einem hohen Grad an Funktionssicherheit durch relativ einfache und betriebssichere Maschinenelemente für eine lange Laufdauer gewährleisten soll, erfordert aufgrund ihrer langen Einbautiefe einen vergleichsweise hohen Platzaufwand in dem regelmäßig sehr beengten Maschineninneren der Rotationsdruckmaschine.From the DE 38 12 678 C3 already a cleaning device for cleaning cylindrical lateral surfaces in a sheet-fed rotary machine is known, which has a roller-shaped cleaning brush, which cleaning brush in the non-sheet-guiding area on the lateral surface of the cylinder during the pressure can be adjusted. The cleaning brush of the DE 38 12 678 C3 Previously known cleaning device, which may also have a bristle field with spirally arranged rows of bristles, is in a suction bell arranged, which has a, extending over the longitudinal extent of the cleaning brush suction air connection. The previously known cleaning device, which is to ensure a smear-free sheet transport with a high degree of functional reliability by relatively simple and reliable machine elements for a long running time, requires a relatively high space requirements in the regularly very cramped machine inside the rotary printing machine due to their long installation depth.

Es besteht daher insbesondere die Aufgabe, eine Reinigungsvorrichtung der eingangs erwähnten Art zu schaffen, die sich durch eine hohe Reinigungswirkung und vorzugsweise auch durch einen geringen Platzbedarf auszeichnet.There is therefore in particular the task of creating a cleaning device of the type mentioned above, which is characterized by a high cleaning effect and preferably also by a small footprint.

Die erfindungsgemäße Lösung dieser Aufgabe besteht bei der Reinigungsvorrichtung der eingangs erwähnten Art darin, dass das Borstenfeld der zumindest einen Reinigungsbürste wenigstens zwei benachbarte Teilbereiche mit gegensinnig umlaufenden Borsten hat, die die in diesen Teilbereichen von der Leitwalze entfernten Schmutzpartikel entweder zu einem zwischen den benachbarten Reinigungsbürsten-Teilbereichen angeordneten gemeinsamen Schmutzauslass oder zu jeweils einem seitlich an den Stirnendbereichen der benachbarten Reinigungsbürsten-Teilbereiche vorgesehenen Schmutzauslass bewegen.The achievement of this object is in the cleaning device of the type mentioned in the fact that the bristle of at least one cleaning brush has at least two adjacent portions with oppositely rotating bristles, which removes the removed in these areas of the guide roller dirt particles either to one between the adjacent cleaning brushes. Moving portions arranged common dirt outlet or each one laterally provided on the front end of the adjacent cleaning brush sections dirt outlet move.

Die erfindungsgemäße Reinigungsvorrichtung weist zumindest eine Reinigungsbürste auf, deren Borstenfeld wenigstens zwei benachbarte Teilbereiche mit gegensinnig umlaufenden Borsten hat. Da die Borsten in diesen Teilbereichen wendelförmig umlaufen und da die von diesen Borsten gelösten Schmutzpartikel nur über diese Teilbereiche und somit über eine im Vergleich zur gesamten Längserstreckung der Reinigungsbürste vergleichsweise kurze Wegstrecke zum Schmutzauslass zu transportieren sind, vermag die Reinigungsbürste der erfindungsgemäßen Reinigungsvorrichtung diese Schmutzpartikel vergleichsweise leicht zu entfernen und aus dem Bereich der Leitwalze abzutransportieren. Da die Reinigungsbürste die gelösten Schmutzpartikel entweder zu einem zwischen den benachbarten Reinigungsbürsten-Teilbereichen angeordneten gemeinsamen Schmutzauslass oder zu jeweils einem seitlich an den Stirnendbereichen der benachbarten Reinigungsbürsten-Teilbereiche vorgesehenen Schmutzauslass bewegt, und da die erfindungsgemäße Reinigungsvorrichtung eine über die Längserstreckung der Reinigungsbürste reichende Absaugglocke somit entbehrlich macht, zeichnet sich die erfindungsgemäße Reinigungsvorrichtung durch eine geringe Einbautiefe und somit durch einen vergleichsweise geringen Platzbedarf aus. Da die gegensinnigen Teilbereiche der Reinigungsbürste die an der Leitwalze befindlichen Schmutzpartikel leicht lösen und im Inneren der Reinigungsvorrichtung bis zum benachbarten Schmutzauslass transportieren können, zeichnet sich die erfindungsgemäße Reinigungsvorrichtung auch durch eine hohe Reinigungswirkung aus.The cleaning device according to the invention has at least one cleaning brush, the bristle field has at least two adjacent portions with oppositely rotating bristles. Since the bristles circulate helically in these partial areas and since the dirt particles dissolved by these bristles are to be transported to the dirt outlet only over these partial areas and thus over a comparatively short distance to the dirt outlet compared to the entire longitudinal extension of the cleaning brush, the cleaning brush of the cleaning device according to the invention is able to carry out these dirt particles comparatively easily to remove and transported away from the area of the guide roller. Because the cleaning brush dissolved the Dirt particles either to a disposed between the adjacent cleaning brush subregions common dirt outlet or to a laterally provided on the Stirnendbereichen the adjacent cleaning brush subregions dirt outlet moves, and since the cleaning device according to the invention thus eliminates a reaching over the longitudinal extent of the cleaning brush suction cup, which is characterized Cleaning device according to the invention by a small installation depth and thus by a comparatively small footprint. Since the opposing portions of the cleaning brush easily dissolve the dirt particles located on the guide roller and can transport inside the cleaning device to the adjacent dirt outlet, the cleaning device according to the invention is also characterized by a high cleaning effect.

Um über die gesamte Längserstreckung der Leitwalze eine gleichbleibend hohe Reinigungswirkung zu erzielen, ist es vorteilhaft, wenn die beiden Teilbereiche des Borstenfeldes der zumindest einen Reinigungsbürste eine etwa gleichgroße Längserstreckung aufweisen und etwa in der Mitte des Borstenfeldes aneinander angrenzen.In order to achieve a consistently high cleaning effect over the entire longitudinal extent of the guide roll, it is advantageous if the two subregions of the bristle field of the at least one cleaning brush have an approximately equal longitudinal extent and adjoin one another approximately in the middle of the bristle field.

Vorteilhafterweise ist vorgesehen, dass die Reinigungsbürste quer zur Leitwalzen-Längserstreckung beweglich gelagert ist und die Leitwalze mittels einer Andruckkraft druckbeaufschlagt. Da bei diesem Erfindungsvorschlag die Reinigungsbürste quer zur Leitwalzen-Längserstreckung beweglich gelagert und mittels einer Andruckkraft gegen die Leitwalze gepresst wird, wird die hohe Reinigungswirkung der erfindungsgemäßen Reinigungsvorrichtung noch zusätzlich begünstigt.Advantageously, it is provided that the cleaning brush is mounted to be movable transversely to the guide roller longitudinal extent and pressurizes the guide roller by means of a pressing force. Since in this invention proposal, the cleaning brush is mounted transversely to the guide roller longitudinal extent movable and pressed by a pressing force against the guide roller, the high cleaning effect of the cleaning device according to the invention is additionally favored.

Da die Reinigungsbürste entsprechend der Leitwalze vergleichsweise lang sein kann, ist es zweckmäßig, wenn die Reinigungsbürste an ihren Bürstenendbereichen und/oder im Bereich des Borstenfeldes vorzugsweise zwischen den Reinigungsbürsten-Teilbereichen beweglich gelagert und/oder von einer Andruckkraft druckbeaufschlagt ist. Eine solche Reinigungsvorrichtung kann auch bei großen und leistungsfähigen RollenRotationsdruckmaschinen mit vergleichsweise langen Leitwalzen eingesetzt werden.Since the cleaning brush can be comparatively long in accordance with the guide roller, it is expedient if the cleaning brush is movably mounted on its brush end regions and / or in the area of the bristle field, preferably between the cleaning brush subareas, and / or is pressurized by a pressure force. Such a cleaning device can also be used on large and powerful roll rotary printing machines be used with comparatively long guide rollers.

Dabei sieht eine besonders einfache und vorteilhafte Ausführungsform gemäß der Erfindung vor, dass als Andruckkraft zumindest eine Druckfeder vorgesehen ist, welche wenigstens ein Reinigungsbürsten-Lager druckbeaufschlagt.In this case, a particularly simple and advantageous embodiment according to the invention provides that at least one compression spring is provided as a pressure force, which pressurizes at least one cleaning brush bearing.

Vorteilhafterweise ist weiterhin vorgesehen, dass die Reinigungsbürste und die ihr zugeordnete Leitwalze einen gemeinsamen Drehantrieb haben. Weisen die Reinigungsbürste und die ihr zugeordnete Leitwalze einen gemeinsamen Drehantrieb auf, wird nicht nur die platzsparende Ausgestaltung der erfindungsgemäßen Reinigungsvorrichtung begünstigt, vielmehr kann die erfindungsgemäße Reinigungsvorrichtung die Leitwalze sowohl bei still stehender Rotationsdruckmaschine als auch während der Produktion bei laufender Papierbahn reinigen. Da auch die Leitwalze mit dem gemeinsamen Drehantrieb in Antriebsverbindung steht, lässt sich die Leitwalze auch bei Stillstand der Rotationsdruckmaschine mit oder ohne über die Leitwalze geführte Papierbahn bewegen und reinigen.Advantageously, it is further provided that the cleaning brush and its associated guide roller have a common rotary drive. If the cleaning brush and the guide roller assigned to it have a common rotary drive, not only is the space-saving design of the cleaning device according to the invention favored, but the cleaning device according to the invention can clean the guide roller both when the rotary printing machine is stationary and during production with the paper web running. Since the guide roller is also in drive connection with the common rotary drive, the guide roller can be moved and cleaned even when the rotary printing press is stationary with or without the paper web guided over the guide roller.

Die Reinigungsvorrichtung kann auch nachträglich noch besonders leicht an vorhandene Rotationsdruckmaschinen montiert werden, wenn der Drehantrieb mit der Leitwalze über wenigstens ein Reibrad in Antriebsverbindung steht, und wenn das Reibrad vorzugsweise die Walzenoberfläche der Leitwalze beaufschlagt.The cleaning device can also be retrofitted very easily to existing rotary printing presses when the rotary drive is in driving connection with the guide roller via at least one friction wheel, and when the friction wheel preferably acts on the roller surface of the guide roller.

Die hohe Reinigungswirkung der erfindungsgemäßen Reinigungsvorrichtung wird noch zusätzlich begünstigt, wenn die Reinigungsbürste im Vergleich zu der ihr zugeordneten Leitwalze gegenläufig drehantreibbar ist.
Dabei sieht eine besonders einfache und platzsparende Ausführungsform gemäß der Erfindung vor, dass die Reinigungsbürste und die ihr zugeordnete Leitwalze einen gemeinsamen Drehantrieb haben.The high cleaning effect of the cleaning device according to the invention is further favored when the cleaning brush is in opposite directions rotatably drivable compared to its associated guide roller.
In this case, a particularly simple and space-saving embodiment according to the invention provides that the cleaning brush and the guide roller assigned to it have a common rotary drive.

Um die erfindungsgemäße Reinigungsvorrichtung auch bei großen und leistungsfähigen Rotationsdruckmaschinen mit vergleichsweise langen Leitwalzen einsetzen zu können, sieht eine Ausführungsform gemäß der Erfindung vor, dass die Welle der zumindest einen Reinigungsbürste 'im Verlauf ihrer Längserstreckung mittels wenigstens einer Wellenlagerung zusätzlich abgestützt ist. Dabei ist es besonders vorteilhaft, wenn zumindest eine Wellenlagerung in der Trennebene zwischen den gegensinnig umlaufenden Borsten der erfindungsgemäßen Reinigungsvorrichtung vorgesehen ist.To the cleaning device according to the invention also in large and To be able to use efficient rotary printing presses with comparatively long guide rollers, an embodiment according to the invention provides that the shaft of the at least one cleaning brush is additionally supported in the course of its longitudinal extent by means of at least one shaft bearing. It is particularly advantageous if at least one shaft bearing is provided in the parting plane between the counter-rotating bristles of the cleaning device according to the invention.

Besonders zweckmäßig ist es, wenn die Reinigungsbürste die zu reinigende Leitwalze federnd beaufschlagt.It is particularly useful when the cleaning brush acts on the guide roller to be cleaned resiliently.

  • Fig. 4 die Reinigungsvorrichtung aus den Fig. 1 bis 3 im Bereich des der Reinigungsbürste einerseits und der Leitwalze andererseits zugeordneten gemeinsamen Drehantriebs.
In den Figuren 1 und 2 ist eine Reinigungsvorrichtung 1 zum Reinigen der zylindrischen Mantelfläche einer Leitwalze 2 dargestellt. Diese Leitwalze 2 ist in einer ansonsten nicht weiter gezeigten Rollen-Rotationsdruckmaschine vorgesehen und soll dort die Papierbahn 3 führen. Die Reinigungsvorrichtung 1 weist dazu eine koaxial zur 4eitwalze, 2 angeordnete Reinigungsbürste 4 auf, die ein Borstenfeld mit wendelförmig umlaufenden Borsten 5 hat. Die Reinigungsbürste 4 ist in dem durch die Papierbahn 3 umgrenzten Freiraum und somit im "Schatten" der von der Papierbahn 3 umschlungenen Leitwalze 2 angeordnet. Diese Reinigungsbürste 4 kann mit ihrem Borstenfeld zumindest während des Reinigungsvorganges die Leitwalze 2 wenigstens bereichsweise reinigend beaufschlagen.It shows:

  • Fig. 3 provided for the cleaning brush shaft bearing of the cleaning device of FIGS. 1 and 2, and
  • Fig. 4, the cleaning device of FIGS. 1 to 3 in the region of the cleaning brush on the one hand and the guide roller on the other hand associated common rotary drive.
In Figures 1 and 2, a cleaning device 1 for cleaning the cylindrical surface of a guide roller 2 is shown. This guide roller 2 is provided in an otherwise not shown roller rotary printing machine and is there to guide the paper web 3. The cleaning device 1 has for this purpose a coaxial with the 4eitwalze, 2 arranged cleaning brush 4, which has a bristle field with helically rotating bristles 5. The cleaning brush 4 is arranged in the bounded by the paper web 3 space and thus in the "shadow" of the looped by the paper web 3 guide roller 2. This cleaning brush 4, with its bristle field at least during the cleaning process, the guide roller 2 act on at least partially cleaning.

Die Reinigungsvorrichtung 1 weist beidseits an ihren Stirnendbereichen jeweils einen Schmutzauslaß 6 auf; über die beidseits an den Stirnendbereichen' der Reinigungsbürste 4 vorgesehenen Schmutzauslässe 6 können die mittels der Reinigungsbürste 4 gelösten Schmutzpartikel abgeführt werden. Da die Reinigungsvorrichtung 1 eine über die Längserstreckung der Reinigungsbürste 4 reichende Absaugglocke entbehrlich macht, und da die hier dargestellte Reinigungsvorrichtung 1 stattdessen an ihren Stirnendbereichen jeweils einen Schmutzauslaß 6 hat, zeichnet sich die Reinigungsvorrichtung 1 durch eine geringe Einbautiefe und somit durch einen vergleichsweise geringen Platzbedarf aus. Um die Schmutzpartikel in der Reinigungsvorrichtung 1 in Richtung zum angrenzenden Schmutzauslaß 6 transportieren zu können, hat die Reinigungsbürste 4 zwei Teilbereiche 7 und mit gegensinnig umlaufenden Borsten, die die in diesen Teilbereichen 7, 8 von der Leitwalze 2 entfernten Schmutzpartikel zum jeweils angrenzenden Schmutzauslaß 6 bewegen. Von den beidseits vorgesehenen Schmutzauslässen 6 ist in Figur 2 nur ein Schmutzauslaß 6 zu sehen. Da die gegensinnigen Teilbereiche 7, 8 der Reinigungsbürste 4 die an der Leitwalze 2 befindlichen Schmutzpartikel leicht lösen und im Inneren der Reinigungsvorrichtung 1 bis zum be-nachbarten Schmutzauslaß 6 transportieren können, zeichnet sich die Reinigungsvorrichtung 1 auch durch eine gute Reinigungswirkung aus.The cleaning device 1 has on both sides at their Stirnendbereichen in each case a dirt outlet 6; On the both sides of the Stirnendbereichen 'of the cleaning brush 4 provided dirt outlets 6, the dissolved by means of the cleaning brush 4 dirt particles can be removed. Because the Cleaning device 1 makes dispensable over the longitudinal extent of the cleaning brush 4 reaching bell, and since the cleaning device 1 shown here instead has a dirt outlet 6 instead at their Stirnendbereichen, the cleaning device 1 is characterized by a small installation depth and thus by a comparatively small footprint. In order to be able to transport the dirt particles in the cleaning device 1 in the direction of the adjacent dirt outlet 6, the cleaning brush 4 has two subregions 7 and counter-rotating bristles which move the dirt particles removed in these subareas 7, 8 from the guide roller 2 to the respective adjacent dirt outlet 6 , Of the dirt outlets 6 provided on both sides, only one dirt outlet 6 can be seen in FIG. Since the opposing portions 7, 8 of the cleaning brush 4 easily solve the dirt particles located on the guide roller 2 and can transport inside the cleaning device 1 to the adjacent dirt outlet 6, the cleaning device 1 is also characterized by a good cleaning effect.
