Description

Die Erfindung betrifft eine Vorrichtung zur Reinigung von Oberflächen von Druckzylindern mithilfe eines Reinigungstuches, das von einer Vorratsrolle über eine Anpreßleiste zu einer Sammelwelle für verschmutztes Reinigungstuch transportiert wird, und mit einer Anstelleinrichtung zum Vorschieben und Zurückziehen der Anpreßleiste in bezug auf den Druckzylinder, für deren Vorschub ein hinter der Anpreßleiste liegender Antrieb vorgesehen ist.The invention relates to a device for cleaning surfaces of printing cylinders by means of a cleaning cloth, which is transported from a supply roll via a contact strip to a collecting shaft for dirty cleaning cloth, and with a Anstelleinrichtung for advancing and retracting the pressure bar with respect to the impression cylinder, for the feed a drive located behind the pressure bar is provided.

Eine Vorrichtung dieser Art ist aus der DE 297 07 975 U1 bekannt. Zylinder von Druckmaschinen, beispielsweise der Gummizylinder von Offset-Druckmaschinen sind unvermeidlich einer gewissen Verschmutzung ausgesetzt. Diese ergibt sich durch Farbreste, Staub, Reste von Betriebsstoffen usw.. Es ist daher üblich, Druckzylinder von Zeit zu Zeit zu reinigen.A device of this kind is from the DE 297 07 975 U1 known. Cylinders of printing presses, for example the blanket cylinder of offset printing presses are inevitably exposed to some contamination. This is the result of paint residues, dust, residues of supplies, etc. It is therefore common to clean impression cylinder from time to time.

Zu diesem Zweck gibt es Reinigungseinheiten, die ein Reinigungstuch, gegebenenfalls unter Zuhilfenahme von Reinigungsmitteln, über die Oberfläche des Zylinders ziehen. Das Tuch wird dabei von einer Vorratsrolle abgegeben und auf eine Sammelwelle für verschmutztes Reinigungstuch aufgewickelt. Zwischen der Vorratsrolle und der Sammelwelle befindet sich eine Anpreßleiste, die das Reinigungstuch gegen die Oberfläche des Zylinders drückt.For this purpose, there are cleaning units that pull a cleaning cloth, possibly with the aid of cleaning agents, over the surface of the cylinder. The cloth is dispensed from a supply roll and wound up on a collecting shaft for dirty cleaning cloth. Between the supply roll and the collecting shaft is a pressure bar which presses the cleaning cloth against the surface of the cylinder.

Da die Anpreßleiste nur von Zeit zu Zeit benötigt wird, ist sie üblicherweise mithilfe eines geeigneten Mechanismus vorschiebbar und zurückziehbar. Zum Vorschieben der Anpreßleiste ist es aus der eingangs genannten Schrift bekannt, einen aufblasbaren Luftschlauch entlang der Anpreßleiste hinter dieser anzuordnen, der im aufgeblasenen Zustand ein zunehmend größeres Volumen einnimmt und die Anpreßleiste vorschiebt. Es kommen auch andere Antriebe in Betracht. Nähere konstruktive Einzelheiten enthält die genannte Druckschrift nicht. Insbesondere wird nicht gesagt, wie die Anpreßleiste zurückgezogen werden soll, wenn sie nicht benötigt wird. Das Ablassen der Luft aus dem Schlauch wird zu diesem Zweck zwar notwendig, aber möglicherweise nicht ausreichend sein.Since the pressure bar is needed only from time to time, it is usually advanceable and retractable by means of a suitable mechanism. For advancing the pressure bar, it is known from the above-mentioned document to arrange an inflatable air hose along the pressure bar behind this, which occupies an increasingly larger volume in the inflated state and advances the pressure bar. There are also other drives into consideration. Further details of construction does not contain the mentioned document. In particular, it is not said how the pressure bar should be withdrawn when it is not needed. Draining air from the hose will be necessary for this purpose, but may not be sufficient.

Eine Vorrichtung zur Reinigung von Zylinderoberflächen in Rotationsdruckmaschinen ist weiterhin aus der deutschen Offenlegungsschrift DE 195 15 721 A1 bekannt. Eine Reinigungsbahn, die senkrecht zur Richtung von Mantellinien der Mantelfläche orientierte Bahnränder aufweist, wird von einer Vorrats- auf eine Wickelspule transportiert. Ein Abschnitt der Reinigungstuchbahn ist mittels eines Andrückelements gegen die zu reinigende Mantelfläche gedrückt. Parallel zur Rotationsachse der zylindrischen Mantelfläche ist ein von einer sich axial erstreckenden Halterung umfasstes Druckelement von einem sich axial erstreckenden Profil übergriffen. Das Profil ist mit einem von unten auf die Reinigungstuchbahn einwirkenden Anpressmaterial versehen.An apparatus for cleaning cylinder surfaces in rotary printing presses is further from the German patent application DE 195 15 721 A1 known. A cleaning web, which has web edges oriented perpendicular to the direction of generatrices of the lateral surface, is transported from a supply reel to a reel spool. A section of the cleaning fabric web is pressed by means of a pressing element against the surface to be cleaned. Parallel to the axis of rotation of the cylindrical lateral surface, a pressure element encompassed by an axially extending holder is overlapped by an axially extending profile. The profile is provided with a pressing material acting from below on the cleaning cloth web.

Das europäische Patentanmeldung EP 0 816 079 A2 zeigt eine Zylinderreinigungsvorrichtung zur Verwendung mit einer Reinigungstuchvorratsrolle, um die ein Reinigungstuch herumgewickelt ist, wobei das Reinigungstuch von der Vorratsrolle zugeführt und zwecks Reinigung der Außenfläche eines Zylinders gegen selbige gedrückt wird, wobei die Vorrichtung ein Rahmenmittel enthält und folgendes umfasst: ein an dem Rahmenmittel angebrachtes Rollenaufnahmemittel, das die Außenfläche der Vorratsrolle in Eingriff nimmt und diese aufnimmt; und ein Rollenstabilisierunsmittel.The European patent application EP 0 816 079 A2 Figure 3 shows a cylinder cleaning apparatus for use with a cleaning cloth supply roll around which a cleaning cloth is wrapped, the cleaning cloth being fed from the supply roll and pressed against the cylinder for cleaning the outer surface of a cylinder, the apparatus including a frame means and comprising: a frame attached to the frame means Roller receiving means which engages and receives the outer surface of the supply roll; and a roller stabilizer.

Aus der internationalen Patentanmeldung WO 01/62497 A1 ist weiterhin ein Stab zum Zuführen von einer Mischung aus Flüssigkeit und Reinigungsmittel für das automatische Reinigen von Druckmaschinenzylinder bekannt.From the international patent application WO 01/62497 A1 Furthermore, a rod for supplying a mixture of liquid and detergent for the automatic cleaning of printing press cylinder is known.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung der eingangs genannten Art mit einer besonders kompakten Anpreßleiste mit integriertem Rückholmechanismus zu schaffen.The invention has for its object to provide a device of the type mentioned above with a particularly compact Anpreßleiste with integrated return mechanism.

Zur Lösung dieser Aufgabe ist die erfindungsgemäße Vorrichtung dadurch gekennzeichnet, dass in der Anpressleiste eine Anzahl von quergerichteten Durchbrüchen vorgesehen ist, in denen Stützleisten angeordnet sind, deren Enden sich an Vorsprüngen an den Innenwänden des Balkenprofils abstützen und dass Federn vorgesehen sind, die in den Durchbrüchen der Anpressleiste angeordnet sind und sich einerseits an den Stützleisten und andererseits innerhalb der Anpressleiste an dieser abstützen.To solve this problem, the device according to the invention is characterized in that in the pressure strip a number of transverse openings is provided, in which support strips are arranged, whose ends are supported on projections on the inner walls of the beam profile and that springs are provided in the openings the pressure strip are arranged and on the one hand to the support strips and on the other hand supported within the pressure bar on this.

Die Anpreßleiste zusammen mit dem zugehörigen Balkenprofil und der integrierten Rückholeinrichtung bildet somit eine kompakte Gesamteinheit, die auch bei beengten Platzverhältnissen innerhalb einer Druckmaschine in der Regel unterzubringen ist.The Anpreßleiste together with the associated beam profile and the integrated return device thus forms a compact overall unit, which is usually accommodate even in tight spaces within a printing press.

Der als vorteilhaftes Ausführungsbeispiel für den Vorschubantrieb für die Anpreßleiste verwendete, expandierbare Schlauch gestattet ebenfalls eine besonders kompakte Bauweise. Zum Expandieren des Schlauchs ist insbesondere Luftdruck geeignet, jedoch könnte auch mit einem anderen Gas oder einem Hydraulikmedium gearbeitet werden.The used as an advantageous embodiment of the feed drive for the pressure bar, expandable hose also allows a particularly compact design. In particular, air pressure is suitable for expanding the hose, but it would also be possible to work with another gas or a hydraulic medium.

Zum Abstützen der Rückholfeder, bevorzugt einer Druckfeder, innerhalb des U-förmigen Balkenprofils sind an den Innenwänden dieses Profils Vorsprünge vorgesehen, die ein Angreifen der Feder ermöglichen. Entsprechend einer Ausführungsform ist eine Anzahl von quer zur Anpreßleiste gerichteten Durchbrüchen in dieser vorgesehen, in die Stützleisten eingefügt sind, deren beiden äußeren Enden sich an Vorsprüngen an der inneren Wandfläche des Balkenprofils abstützen.To support the return spring, preferably a compression spring, within the U-shaped beam profile projections are provided on the inner walls of this profile, which allow attacking the spring. According to one embodiment, a number of transversely directed to the contact strip breakthroughs are provided in this, are inserted in the support strips whose two outer ends are supported on projections on the inner wall surface of the beam profile.

Die Anpreßleiste besteht vorzugsweise, wie an sich bekannt, aus einem Kern aus Metall mit einer für die Erfassung des Reinigungstuchs vorgesehenen Arbeitsfläche aus Gummi oder einem elastomeren Kunststoff.The pressure bar preferably consists, as is known, of a core of metal with a working surface of rubber or an elastomeric plastic intended for the detection of the cleaning cloth.

Im folgenden werden bevorzugte Ausführungsbeispiele der Erfindung anhand der beigefügten Zeichnung näher erläutert.

Anschließend soll eine Ausführungsform der Erfindung unter Bezugnahme auf die Fig. 1 bis 3 erläutert werden.Subsequently, an embodiment of the invention with reference to the Fig. 1 to 3 be explained.

In der Zeichnung ist eine Anpreßleiste mit 10 und ein im Querschnitt U-förmiges Balkenprofil, das die Anpreßleiste 10 aufnimmt, mit 12 bezeichnet. In Fig. 2 und 3 ist der Umfang eines Druckzylinders, zu dessen Reinigung die Anpreßleiste vorgesehen ist, mit 14 bezeichnet worden. Am Grund des Balkenprofils 12 befinden sich eine durchlaufende Nut 16, in der ein Schlauch 18 liegt. Dieser Schlauch kann, wie ein Vergleich von Fig. 2 und 3 zeigt, durch Einleiten eines geeigneten Mediums, insbesondere durch Einleiten von Druckluft erweitert werden. In der expandierten Stellung übt der Schlauch 18 Druck aus auf eine untere Leiste 20 an der Unterseite der Anpreßleiste, die mit 20 bezeichnet ist. Die Leiste 20 weist an ihrer Unterseite eine Auskehlung 22 auf, die sich über die Länge der Leiste erstreckt und den Schlauch 18 aufnimmt.In the drawing, a pressure bar with 10 and a cross-sectionally U-shaped beam profile, which receives the pressure bar 10, denoted by 12. In FIGS. 2 and 3 is the scope of a printing cylinder, for the cleaning of the pressure bar is provided, has been designated 14. At the bottom of the beam profile 12 there is a continuous groove 16 in which a hose 18 is located. This hose can, as a comparison of FIGS. 2 and 3 shows are extended by introducing a suitable medium, in particular by introducing compressed air. In the expanded position, the hose 18 exerts pressure on a lower bar 20 at the bottom of the pressure bar, which is designated 20. The strip 20 has on its underside a groove 22 which extends over the length of the strip and the tube 18 receives.

Die Anpreßleiste 10 besteht insgesamt aus Metall und besitzt auf der nach rechts in Fig. 2 und 3 liegenden Seite, die dem Druckzylinder 14 zugewandt ist, eine Gummileiste 24, die nicht nur aus Gummi im eigentlichen Sinne bestehen muß, sondern auch aus geeigneten Kunststoffen, insbesondere elastomeren Kunststoffen, hergestellt sein kann.The Anpreßleiste 10 is made entirely of metal and has on the right in FIGS. 2 and 3 lying side, which faces the impression cylinder 14, a rubber strip 24, which must not only consist of rubber in the true sense, but also from suitable plastics, in particular elastomeric plastics, can be made.

Die Gummileiste 24 ist ein Strangprofil. Sie weist, wie der in Fig. 2 und 3 gezeigte Querschnitt erkennen läßt, einen C-förmigen Hauptteil auf, der in Fig. 2 und 3 allerdings in umgekehrter Orientierung gezeigt ist. Innerhalb des C-förmigen Bogens verlaufen Stützfüße 26,28,30,32 zu dem aus Metall bestehenden Kern 34. Der C-förmige Bogen der Gummileiste 24 weist an beiden Enden Erweiterungen 36,38 auf, die in entsprechende Nuten des Kerns 34 der Anpreßleiste 10 in Längsrichtung eingeschoben werden können.The rubber strip 24 is an extruded profile. She points out how the in FIGS. 2 and 3 shown cross-section, a C-shaped main part, the in FIGS. 2 and 3 but shown in reverse orientation. Within the C-shaped arch, support legs 26,28,30,32 extend to the metal core 34. The C-shaped arc of the rubber strip 24 has extensions 36,38 at both ends which engage corresponding grooves of the core 34 of the pressure bar 10 can be inserted in the longitudinal direction.

Der Kern 34 der Anpreßleiste 10 weist in Abständen liegende, quer zur Längsrichtung gerichtete Durchbrechungen 40,42 auf, in denen Stützleisten 44,46 liegen. Die Stützleisten 44,46 befinden sich in Fig. 1, 2 und 3 in senkrechter Orientierung und damit parallel zur Zeichenebene. Die Stützleisten 44,46 stützen sich, wie Fig. 2 und 3 erkennen lassen, im Inneren des Balkenprofils 12 an von dessen Wänden vorspringenden Vorsprüngen 48,50 ab. Diese Vorsprünge 48,50 sind als durchlaufende Leisten an den Innenwänden des Balkenprofils 12 ausgebildet.The core 34 of the contact strip 10 has spaced, transverse to the longitudinal direction openings 40,42 in which support strips 44,46 lie. The support strips 44,46 are located in Fig. 1 . 2 and 3 in a vertical orientation and thus parallel to the plane of the drawing. The support strips 44,46 support, as FIGS. 2 and 3 let recognize in the interior of the beam profile 12 at protruding from its walls projections 48,50. These projections 48,50 are formed as continuous strips on the inner walls of the beam profile 12.

Zur Vermeidung von Missverständnissen soll hier ergänzend darauf hingewiesen werden, dass die untere Leiste 20, die sich an dem Schlauch 18 abstützt, ein Teil der Anpreßleiste 10 bildet. Die Anpreßleiste in ihrer Gesamtheit wird von den Durchbrechungen 40,42 durchlaufen, in denen sich die Stützleisten 44,46 befinden. Dies ist in Fig. 1 besser zu erkennen als in Fig. 2 und 3.To avoid misunderstandings, it should additionally be pointed out here that the lower strip 20, which is supported on the hose 18, forms part of the contact strip 10. The pressure bar in its entirety is traversed by the openings 40,42 in which the support strips 44,46 are located. This is in Fig. 1 better to recognize than in FIGS. 2 and 3 ,

Die Stützleisten 44,46 stützen sich von innen an den Vorsprüngen 48,50 ab, wie in Fig. 2 und 3 zu erkennen ist.The support strips 44,46 are based on the inside of the projections 48,50 from, as in FIGS. 2 and 3 can be seen.

Die Stützleisten 44,46 dienen zur Abstützung einer Schraubendruckfeder 52, die sich an ihrem anderen Ende am Boden einer Bohrung 54 abstützt, die sich im Boden der Anspreßleiste 10 auf der dem Schlauch 18 zugewandten Seite befindet.The support strips 44,46 serve to support a helical compression spring 52 which is supported at its other end at the bottom of a bore 54 which is located in the bottom of the Anspreßleiste 10 on the hose 18 side facing.

Die Stützleisten 44,46 treten zwar auf beiden gegenüberliegenden Seiten aus der Querschnittsfläche der Anpreßleiste 10 aus, jedoch geschieht dies innerhalb von nutartigen Vertiefungen 56,58, die sich auf beiden gegenüberliegenden Seiten der Anpreßleiste 10 in deren Längsrichtung erstrecken.Although the support strips 44,46 occur on both opposite sides of the cross-sectional area of the pressure bar 10, but this happens within groove-like depressions 56,58, which extend on both opposite sides of the pressure bar 10 in the longitudinal direction.

Innerhalb dieser Vertiefungen 56,58 liegen auch die Vorsprünge 48,50 an den inneren Wandflächen des Balkenprofils 12. Auf diese Weise kann die Anpreßleiste 10 über einen begrenzten Weg innerhalb des Balkenprofils 12 verschoben werden und auf diese Weise an den Druckzylinder 14 angestellt und von diesem zurückgezogen werden.Within these recesses 56,58 are also the projections 48,50 on the inner wall surfaces of the beam profile 12. In this way, the pressure bar 10 can be moved over a limited path within the beam profile 12 and made in this way to the pressure cylinder 14 and from this be withdrawn.

Die Stützleisten, die sich an den Vorsprung 48,50 abstützen, bilden ihrerseits ein Widerlager für die Schraubendruckfedern 52, die bestrebt sind, die Anpreßleiste 10 aus der vorgerückten Stellung zurückzuschieben.The support strips, which are supported on the projection 48,50, in turn, form an abutment for the helical compression springs 52, which endeavor to push back the pressure bar 10 from the advanced position.

Bei dieser Verschiebebewegung der Anpreßleiste bilden die seitlichen Flanken der nutartigen Vertiefungen 56,58 im Zusammenwirken mit den seitlichen Flanken der rippenförmigen Vorsprünge 48,50 korrespondierende Anschlagpaare.In this sliding movement of the contact strip, the lateral flanks of the groove-like depressions 56, 58 in cooperation with the lateral flanks of the rib-shaped projections 48, 50 correspond to corresponding pairs of stops.

In dem rechts in allen Zeichnungen liegenden Teil der Anpreßleiste 10, also demjenigen Teil, der dem Druckzylinder 18 zugewandt ist und der die Gummileiste 24 trägt, befindet sich eine Anzahl von in Abständen über die Länge verteilten Gewindebohrungen 60.In the right in all drawings lying part of the Anpreßleiste 10, so that part which faces the pressure cylinder 18 and carries the rubber strip 24, there is a number of spaced at intervals over the length of tapped holes 60th

Die Positionen der Gewindebohrungen 60 entsprechen den Positionen der Schraubendruckfedern 52. In die Gewindebohrungen 60 ist ein Gewindekopf eingeschraubt, der mit 62 bezeichnet ist. Von dem Gewindekopf 62 geht koaxial nach links ein Schaft 64 aus. Dieser Schaft 64 durchdringt die Stützleisten 44,46, die sich jeweils zwischen dem Gewindekopf und der Schraubendruckfeder 52 befinden, in nicht bezeichneten Bohrungen. Auf der den Schraubendruckfedern zugewandten Seite dient der Schaft 64 als Führung für die Schraubendruckfeder. Der Außendurchmesser des Schafts 64 entspricht im wesentlichen dem Innendurchmesser der Schraubendruckfeder 52.The positions of the threaded holes 60 correspond to the positions of the helical compression springs 52. In the threaded holes 60, a threaded head is indicated, which is designated 62. From the threaded head 62, a shaft 64 extends coaxially to the left. This shaft 64 penetrates the support strips 44,46, which are respectively between the threaded head and the helical compression spring 52, in not designated holes. On the screw compression springs facing side of the shaft 64 serves as a guide for the helical compression spring. The outer diameter of the shaft 64 substantially corresponds to the inner diameter of the helical compression spring 52.

Ein Vergleich von Fig. 2 und 3 läßt die Arbeitsweise der erfindungsgemäßen Vorrichtung erkennen. Fig. 2 zeigt die Anpreßleiste in der zurückgezogenen Stellung oder Ruhestellung. Der Schlauch 18 ist weitgehend entspannt.A comparison of FIGS. 2 and 3 lets recognize the operation of the device according to the invention. Fig. 2 shows the pressure bar in the retracted position or rest position. The tube 18 is largely relaxed.

Durch die Wirkung der Schraubendruckfedern 52, die sich an den Stützleisten 44,46 abstützen, wird das der Schlauchseite zugewandte Teil der Anpreßleiste von den Federn beaufschlagt und die Anpreßleiste nach links in Fig. 2 und 3, also in die Ruhestellung verschoben.By the action of the helical compression springs 52, which are supported on the support strips 44,46, the hose side facing the part of the pressure bar is acted upon by the springs and the pressure bar to the left in FIGS. 2 and 3 , so moved to the rest position.

Wenn andererseits der Schlauch 18 aufgeblasen, das heißt mit einem pneumatischen oder hydraulischen Medium gefüllt wird, verschiebt er die Anpreßleiste nach rechts in Fig. 2 und 3 bis zur Anlage gegen den Druckzylinder 14, während die Schraubendruckfeder 52 zusammengepreßt wird.On the other hand, if the hose 18 inflated, that is filled with a pneumatic or hydraulic medium, he moves the pressure bar to the right in FIGS. 2 and 3 until it rests against the impression cylinder 14 while the helical compression spring 52 is compressed.

Der Schaft 64 dient im übrigen zur Führung der Stützleisten 46,48, die andernfalls aus den Durchbrechungen 40,42 herausfallen könnten. Durch die Drehung des Gewindekopfes 62 läßt sich dessen axiale Position einstellen.The shaft 64 also serves to guide the support strips 46,48, which could otherwise fall out of the openings 40,42. By the rotation of the threaded head 62, its axial position can be adjusted.

Diese Position beeinflußt zugleich den Mindestabstand zwischen der Stützleiste 46 (Fig. 2 und 3) und dem Kern 43 der Anpreßleiste 10, wie es in Fig. 2 gezeigt ist. Dies hat wiederum Einfluß auf die Wirkung der Schraubendruckfeder 52.This position also affects the minimum distance between the support strip 46 ( FIGS. 2 and 3 ) and the core 43 of the pressure bar 10, as it is in Fig. 2 is shown. This in turn has an influence on the action of the helical compression spring 52.
