Description

Die Erfindung betrifft eine Einrichtung zum Reinigen eines Übertragungszylinders einer Rotationsdruckmaschine während des Betriebes nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a device for cleaning a transfer cylinder of a rotary printing press during operation according to the preamble of claim 1.

Aus der DE 36 01 539 A1 ist eine Vorrichtung zum Reinigen eines Übertragungszylinders einer Druckpresse bekannt, mit deren Hilfe während des Betriebes Staub und Lint von einem Übertragungszylinder entfernt werden kann. Dabei werden Bürsten periodisch gegen den Übertragungszylinder gedrückt, der vorzugsweise ein Gummituchzylinder ist, wobei Staub und Lint von diesem abgefegt und einem sogenannten Lintfänger zugeführt werden. Diese Vorrichtung ist an der Peripherie des Übertragungszylinders angeordnet und beidseitig an den Druckwerkseitenwänden befestigt. Es kann als störend empfunden werden, daß diese Vorrichtung an der Peripherie des Übertragungszylinders angeordnet ist, da dadurch Arbeiten an der Maschine beeinträchtigt werden. Des weiteren ist aus der DE-AS 11 32 151 eine einen Schaber aufweisende Reinigungsvorrichtung bekannt. Der Schaber ist dabei im Zwickel zwischen Gummituchzylinder und Gegendruckzylinder angeordnet. Eine ähnliche Vorrichtung ist auch aus dem US-Patent 29 61 953 bekannt. Die US 35 08 711 offenbart eine Reinigungsvorrichtung mit einem Sprühdüsenbalken im Bahneinlaufspalt, also im Zwickel zwischen der Bedruckstoffbahn und dem Gummituchzylinder. Aus dem DE-Patent 36 10 697 ist eine herkömmliche sogenannte Fingerschutzspindel (Schutzleiste) bekannt, in Form eines Winkels. Es wird, wie bei allen bekannten Reinigungsvorrichtungen zusätzlicher Platz für diese benötigt. Die US 15 62 010 zeigt eine schwenkbare, einen Zylinderspalt abdeckende winkelförmige Schutzleiste.DE 36 01 539 A1 discloses a device for cleaning a transfer cylinder of a printing press, with the aid of which dust and lint can be removed from a transfer cylinder during operation. Brushes are pressed periodically against the transfer cylinder, which is preferably a rubber blanket cylinder, dust and lint being swept away by the latter and being fed to a so-called lint catcher. This device is arranged on the periphery of the transfer cylinder and fastened on both sides to the printing unit side walls. It can be seen as a nuisance that this device is arranged on the periphery of the transfer cylinder, since this affects work on the machine. Furthermore, a cleaning device having a scraper is known from DE-AS 11 32 151. The scraper is arranged in the gusset between the blanket cylinder and the impression cylinder. A similar device is also known from US Pat. No. 2,961,953. US 35 08 711 discloses a cleaning device with a spray nozzle bar in the web inlet gap, that is in the gusset between the printing material web and the blanket cylinder. From DE patent 36 10 697 a conventional so-called finger protection spindle (protective strip) is known, in the form of an angle. As with all known cleaning devices, additional space is required for these. US 15 62 010 shows a pivotable, angular protective strip covering a cylinder gap.

Hiervon ausgehend ist es die Aufgabe der Erfindung, eine Vorrichtung zum Reinigen eines Übertragungszylinders einer Rotationsdruckmaschine so auszubilden und anzuordnen, daß sie keinen zusätzlichen Raum beansprucht und weder während des Betriebes noch bei Betriebsunterbrechungen stört. Diese Aufgabe wird durch die Anwendung der Merkmale des kennzeichnenden Teils des Anspruchs 1 gelöst.Proceeding from this, it is the object of the invention to design and arrange a device for cleaning a transfer cylinder of a rotary printing press in such a way that it does not take up any additional space and does not interfere either during operation or during business interruptions. This object is achieved by applying the features of the characterizing part of claim 1.

Da aus Sicherheitsgründen im Bereich der Einlaufspalte jeweils auch Schutzleisten benötigt werden, ergibt sich ein wesentlicher Vorteil der Erfindung dadurch, daß die für die Reinigung der Zylinder benötigten Mittel in oder hinter der Schutzleiste angeordnet sind, wo sie praktisch nicht stören und wobei auch die für die Halterung und Einstellung erforderlichen Mittel, beispielsweise die Hebel zumAusschwenken jeweils nur einmal benötigt werden. Ein Ausführungsbeispiel wird anhand der Zeichnungen erläutert. In diesen zeigt jeweils schematisch.

  • Fig. 1 den linken Teil eines in einer Druckwerkseitenwand gelagerten zu reinigenden Zylinders und
  • Fig. 2 eine Seitenansicht des Zylinders mit teilweiser Darstellung der benachbarten Zylinder.
Since protective strips are also required in the area of the inlet gaps for safety reasons, a significant advantage of the invention results from the fact that the means required for cleaning the cylinders are arranged in or behind the protective strip, where they practically do not interfere, and also those for Bracket and adjustment required means, for example, the levers for swinging out are only required once. An embodiment is explained with reference to the drawings. In these each shows schematically.
  • Fig. 1 shows the left part of a cylinder mounted in a printing unit wall to be cleaned and
  • Fig. 2 is a side view of the cylinder with a partial representation of the adjacent cylinder.

Die erfindungsgemäße Schutz- und Reinigungsvorrichtung 1 ist an einem in einer Seitenwand 2 gelagerten Gummituchzylinder 3 angeordnet bzw. an diesen anstellbar. Die Lagerung des Gummituchzylinders 3 kann beidseitig, wie ein Fig. 1 angedeutet, über Zapfen 4 erfolgen. Die Ausbildung der erfindungsgemäßen Schutz- und Reinigungsvorrichtung 1 kann auf der linken Seite des Gummituchzylinders 3 in der gleichen Weise ausgeführt werden.The protection and cleaning device 1 according to the invention is arranged on a blanket cylinder 3 mounted in a side wall 2 or can be adjusted to it. The blanket cylinder 3 can be supported on both sides, as indicated in FIG. 1, by means of pins 4. The protection and cleaning device 1 according to the invention can be designed in the same way on the left side of the blanket cylinder 3.

Wie beispielsweise aus der DE-PS 36 10 697 bekannt ist, fordern Sicherheitsbestimmungen, daß zur Vermeidung von Unfällen im Einlaufspalt zweier gegeneinander rotierender Zylinder ein sogenannter Fingerschutz vorgesehen wird. Dieser besteht üblicherweise aus einer verschwenk- bzw. verschiebbaren Schutzleiste, die gemäß den Fig. 1 und 2 vorzugsweise einen rechtwinkligen oder auch halbkreisförmigen Querschnitt aufweist. Die Schutzleiste 6 kann an einer Traverse 7 angeordnet sein, die beidseitig innerhalb der Druckwerkseitenwände 2 verschwenkbar gehalten ist. An oder in der Traverse 7 ist gemäß der vorliegenden Erfindung ein Saugrohr 8 positioniert, mit dem der Staub, Lint und Schmutz von den in Achsrichtung des zur reinigenden Zylinders angeordneten Bürsten 9 bzw. aus deren Umgebung abgesaugt werden, der mittels der Bürsten 9 vom dem Druckwerkzylinder 3, beispielsweise einem ein Gummituch 5 tragenden Zylinder abgetragen wird.As is known, for example, from DE-PS 36 10 697, safety regulations require that so-called finger protection is provided in order to avoid accidents in the inlet gap of two cylinders rotating against each other. This usually consists of a pivotable or displaceable protective strip, which according to FIGS. 1 and 2 preferably has a rectangular or semicircular cross section. The protective strip 6 can be arranged on a crossmember 7, which is pivotally held on both sides within the printing unit side walls 2. According to the present invention, a suction pipe 8 is positioned on or in the crossmember 7, with which the dust, lint and dirt are sucked off from the brushes 9 arranged in the axial direction of the cylinder to be cleaned, or from the surroundings thereof, by means of the brushes 9 from the Printing unit cylinder 3, for example a cylinder carrying a blanket 5, is removed.

Das Saugrohr 8 ist mit einem flexiblen schematisch angedeuteten Schlauch 10 verbunden, der über die Druckwerkseitenwand nach außen zu einer nicht dargestellten Saugvorrichtung führen kann. Zum An- und Abstellen der Schutz- und Reinigungsvorrichtung 1 ist vorzugsweise beidseitig an den Enden jeweils ein verschwenkbarer Hebel 11 vorgesehen, der sich jeweils an einer Seite drehbar an Halterungen 12 abstützt und an dessen andere Seite jeweils ein Ende der Traverse 7 befestigt ist. An den zu reinigenden Gummituchzylinder 3 ist ein weiterer Zylinder 13 angestellt, der je nach Aufbau der Maschine ein Gegendruckzylinder, ein weiterer Gummituchzylinder oder, wie im vorliegenden Fall ein Plattenzylinder 13 sein kann. Im vorliegenden Fall ist an den Gummituchzylinder 3 ein weiterer Gummituchzylinder 14 angestellt, so daß ein zwischen den Zylindern 3, 14 durchgeführter Druckträger, beispielsweise eine Papierbahn, beidseitig bedruckt werden kann. Es versteht sich, daß an den weiteren Gummituchzylinder 14 auch derartige Schutz- und Reinigungsvorrichtungen angebaut werden können.The suction pipe 8 is connected to a flexible, schematically indicated hose 10, which can lead to a suction device (not shown) via the printing unit side wall. For turning the protective and cleaning device 1 on and off, a pivotable lever 11 is preferably provided on both ends at the ends, which is rotatably supported on brackets 12 on one side and one end of the cross member 7 is attached to the other side of each. On the one to be cleaned Blanket cylinder 3 is another cylinder 13 employed, which, depending on the construction of the machine, can be an impression cylinder, another blanket cylinder or, as in the present case, a plate cylinder 13. In the present case, a further blanket cylinder 14 is attached to the blanket cylinder 3, so that a printing medium, for example a paper web, carried out between the cylinders 3, 14 can be printed on both sides. It goes without saying that such protective and cleaning devices can also be attached to the further blanket cylinder 14.

Wenn die Zylinder 3, 13 in Richtung der Pfeile 15, 16 rotieren, entsteht ein Einlaufspalt 19. Bei Drehrichtungsumkehr der Zylinder 3, 13 ergibt sich auf der anderen Seite ein Einlaufspalt 20. Die erfindungsgemäße Schutz- und Reinigungsvorrichtung ist deshalb vorzugsweise zweifach, d.h., an je einem Einlaufspalt 19, 20 vorgesehen, wie bei 1 und 17 angedeutet ist.When the cylinders 3, 13 rotate in the direction of the arrows 15, 16, an inlet gap 19 is created. When the direction of rotation of the cylinders 3, 13 is reversed, an inlet gap 20 results on the other side. The protection and cleaning device according to the invention is therefore preferably double, ie provided at an inlet gap 19, 20, as indicated at 1 and 17.

Gemäß der Erfindung wird also die vorangehend beschriebene Schutz- und Reinigungsvorrichtung 1, 17 jeweils im Bereich des etwa dreieckförmigen Einlaufspaltes 19 und/oder 20 angeordnet. Dadurch wird praktisch kein zusätzlicher Raum beansprucht und die Schutz- und Reinigungsvorrichtung 1 bzw. 17 stört bei Handhabungen an der Druckmaschine nicht. Da, wie bereits eingangs erläutert wurde aus Sicherheitsgründen im Bereich der Einlaufspalte jeweils auch Schutzleisten benötigt werden, ergibt sich ein wesentlicher Vorteil der Erfindung dadurch, daß die für die Reinigung der Zylinder benötigten Mittel in oder hinter der Schutzleiste angeordnet sind, wo sie paraktisch nicht stören und wobei auch die für die Halterung und Einstellung erforderlichen Mitteln, beispielsweise die Hebel 11 jeweils nur einmal benötigt werden. Die Einstellung bzw. Justage der Schutzleiste 6 und der Bürsten 9 ist bei 18 angedeutet.According to the invention, the protective and cleaning device 1, 17 described above is therefore arranged in the region of the approximately triangular inlet gap 19 and / or 20. As a result, practically no additional space is required and the protection and cleaning device 1 or 17 does not interfere with handling on the printing press. Since, as already explained at the beginning, protective strips are also required in the area of the inlet gaps for safety reasons, a significant advantage of the invention results from the fact that the means required for cleaning the cylinders are arranged in or behind the protective strip, where they do not interfere paractically and the means required for mounting and adjustment, for example the levers 11, are also only required once. The setting or adjustment of the protective strip 6 and the brushes 9 is indicated at 18.

Im Rahmen des der Erfindung zugrundeliegenden allgemeinen Gedanken können auch anstelle der Bürsten 9 andere Reinigungselemente verwendet werden, wobei es zwar vorteilhaft, aber nicht zwingend erforderlich ist, daß mit einer Absaugvorrichtung gearbeitet wird. Die Schutzleisten 6 können aus Winkeln oder halbkreisförmigen Profilen in einfacher Weise hergestellt werden. Die Verschwenkung der Hebel 11 kann manuel oder vorzugsweise mit bekannten elektrischen oder mechanischen Einrichtung erfolgen, was auch für die Justier- und Abstelleinrichtung 18 gilt.Within the framework of the general idea on which the invention is based, 9 can also be used instead of the brushes Cleaning elements are used, although it is advantageous, but not absolutely necessary, to work with a suction device. The protective strips 6 can be produced in a simple manner from angles or semicircular profiles. The pivoting of the levers 11 can be done manually or, preferably, with known electrical or mechanical devices, which also applies to the adjusting and parking device 18.
