Abstract

Beim Durchlaufen des Zylinderkanals (2) entsteht an den Auftragwalzen (4) von Farb-, Feucht- oder Lackierwerken in Bogen-Offset-Druckmaschinen ein Stoß sowohl am Kanalanfang als auch am Kanalende. Die dadurch entstehende unterschiedliche Abplattung der weichen Auftragwalzen (4) verursacht Walzenstreifen, die vermieden wer den sollen. Dazu sind die Auftragwalzen (4) und die vorgelagerte Walze (5) mit Federn gegeneinander verspannt, so daß ihr Lagerspiel beseitigt und der Achsabstand konstant wird. Dieser Zustand bleibt auch beim Kanaldurchgang erhalten. Damit ist der Flüssigkeitstransport zwischen Auftragwalzen und den ihnen vorgeschalteten Walzen konstant.As the cylinder channel (2) passes through, the application rollers (4) of inking, dampening or coating units in sheet-fed offset printing machines produce a joint both at the beginning and end of the channel. The resulting different flattening of the soft application rollers (4) causes roller strips that should be avoided. For this purpose, the application rollers (4) and the upstream roller (5) are braced against one another with springs, so that their bearing play is eliminated and the center distance becomes constant. This condition is retained even when the channel passes. This means that the liquid transport between application rollers and the rollers upstream of them is constant.

Description

Die Erfindung betrifft eine Vorrichtung entsprechend dem Oberbegriff des ersten Patentanspruchs.The invention relates to a device according to the preamble of the first claim.

Es ist bei Walzenwerken an Bogendruckmaschinen bekannt, daß die Auftragwalzen zuer exakten Übertragung von Farbe, Feuchtmittel oder Lack mit einem bestimmten Druck an den Plattenzylinder angestellt werden müssen. Gleichzeitig müssen die Auftragwalzen auch zu den übrigen mit ihnen in Kontakt stehenden Walzen des Walzenwerkes einstellbar gelagert sein.It is known in the case of roller mills on sheet-fed printing machines that the application rollers have to be turned on the plate cylinder with a certain pressure in order to transfer ink, dampening solution or lacquer precisely. At the same time, the applicator rollers must also be adjustable in relation to the other rollers of the roller mill that are in contact with them.

Durch den zwischen den Auftragwalzen und dem Plattenzylinder bestehende Anpreßdruck erfolgt infolge des Zylinderkanals während einer Plattenzylinderumdrehung ein doppelter Lastwechsel.Due to the contact pressure between the application rollers and the plate cylinder, a double load change occurs as a result of the cylinder channel during a plate cylinder revolution.

Durch diesen Lastwechsel und durch das vorhandene Lagerspiel ändert sich auch der Achsabstand und damit auch der Anpreßdruck zwischen der Auftragwalze und der mit ihr zusammenwirkenden Walze, die meist als Reibwalze ausgebildet ist. Dies bedeutet, daß sich die Kontaktfläche beider Walzen zyklisch ändert.This change in load and the existing bearing play also change the center distance and thus also the contact pressure between the applicator roller and the roller interacting with it, which is usually designed as a friction roller. This means that the contact area of both rollers changes cyclically.

Es hat sich gezeigt, daß sich insbesondere der am Druckanfang auftretende Lastwechsel besonders nachteilig auswirkt, denn der durch den Lastwechsel hervorgerufene Stoß ergibt eine größere Kontaktfläche infolge höherer Pressung und damit eine geringere Farb-, Feuchtmittel- oder Lackführung, was sich im Druckergebnis als Walzenstreifen niederschlägt. Dieser Stoß wird mit wachsender Maschinengeschwindigkeit verstärkt, so daß der Walzenstreifen besonders bei hohen Maschinengeschwindigkeiten zur Auswirkung kommt.It has been shown that, in particular, the load change occurring at the start of printing has a particularly disadvantageous effect, since the impact caused by the load change results in a larger contact area as a result of higher pressure and thus less ink, dampening solution or varnish guidance, which is reflected in the printing result as roller strips . This bump is growing with machines speed increased so that the roller strip is particularly effective at high machine speeds.

Dieser Nachteil ist jedoch nicht einfach durch eine Erhöhung des Anpreßdruckes zwischen Reib- und Auftragwalze ausgleichbar, denn es kommt dann zu einer Abplattung der Auftragwalze während des Maschinenstillstandes an der Kontaktstelle beider Walzen.However, this disadvantage cannot be compensated for simply by increasing the contact pressure between the friction roller and the application roller, since the application roller then becomes flattened during the machine standstill at the contact point of the two rollers.

Der Erfindung liegt deshalb die Aufgabe zugrunde, eine Lagerung für die Walzen eines Walzenwerkes einer Druckmaschine zu schaffen, bei der infolge eines auf die Auftragwalze wirkenden Stoßes keine Zunahme der Pressung zwischen Auftragwalze und der mit ihr zusammenwirkenden Walze erfolgt.The invention is therefore based on the object of providing storage for the rollers of a roller unit of a printing press, in which there is no increase in the pressure between the application roller and the roller interacting with it as a result of an impact acting on the application roller.

Gelöst wird diese Aufgabe durch eine Vorrichtung entsprechend dem Kennzeichen des ersten Patentanspruchs.This object is achieved by a device according to the characterizing part of the first claim.

Eine derartige Vorrichtung hat den Vorteil, daß durch den festgelegten Achsabstand beider Walzen keine Zunahme der Pressung erfolgen kann. Weiterhin ist von Vorteil, daß der Stoß in das Maschinengestell leitbar ist bzw. an eine andere Stelle des Walzenwerkes, an der sich die Auswirkungen des Stoßes nicht mehr auf das Druckergebnis auswirken können.Such a device has the advantage that no increase in pressure can occur due to the fixed center distance of the two rollers. Another advantage is that the impact can be conducted into the machine frame or to another location on the roller mill where the impact of the impact can no longer affect the printing result.

Nachfolgend ist die Erfindung an einem Ausführungsbeispiel näher erläutert.

  • Fig. 1 zeigt schematisch einen Plattenzylinder und ein Walzenwerk.
  • Fig. 2 zeigt einen Ausschnitt des Walzenwerkes mit schematisch dargestellten Vorrichtungen zum Spielfreimachen der Lagerung.
The invention is explained in more detail below using an exemplary embodiment.
  • Fig. 1 shows schematically a plate cylinder and a roller mill.
  • Fig. 2 shows a section of the roller mill with schematically illustrated devices for clearance clearance of the storage.

Der Plattenzylinder 1 weist einen Zylinderkanal 2 auf, in dem bekannte und hier nicht näher erläuterte Mittel zum Befestigen der Druckplatte vorgesehen sind. An den Plattenzylinder 1 ist eine zu diesem und zu einer Reibwalze 5 einstellbare Auftragwalze 4 angestellt. Die Reibwalze 5 wirkt mit einer weiteren als Schöpfwalze 6 ausgebildeten Walze zusammen.The plate cylinder 1 has a cylinder channel 2, in which known means (not explained here) for fastening the pressure plate are provided. On the plate cylinder 1, an applicator roller 4 which is adjustable with respect to this and to a friction roller 5 is employed. The friction roller 5 interacts with another roller designed as a scoop roller 6.

Für eine gute Übertragung des durch die Walzen 4, 5, u. 6 geforderten Mediums ist die Auftragwalze 4 mit einem definierten Anpreßdruck an den Plattenzylinder 1 angestellt. Üblicherweise sind Auftragwalzen mit einer elastischen Schicht wie Gummi oder dgl. überzogen. Während der Rotation des Plattenzylinders 1 bricht infolge des Zylinderkanals 2 die zwischen Plattenzylinder 1 und Auftragwalze 4 bestehende Druckspannung schlagartig zusammen und wird, wenn der Druckanfang 3 mit der Auftragwalze 4 'zusammen kommt ebenso schlagartig wieder aufgebaut. Der hieraus resultierende Stoß muß nun so aufgefangen werden, daß sich die zwischen Auftragwalze 4 und Reibwalze 5 bestehende Druckspannung nicht verändert.For a good transfer of the through the rollers 4, 5, u. 6 required medium, the applicator roller 4 is applied to the plate cylinder 1 with a defined contact pressure. Application rollers are usually covered with an elastic layer such as rubber or the like. During the rotation of the plate cylinder 1, as a result of the cylinder channel 2, the compressive stress existing between the plate cylinder 1 and the application roller 4 suddenly collapses and is also suddenly rebuilt when the start of printing 3 comes together with the application roller 4 '. The resulting impact must now be absorbed in such a way that the compressive stress existing between applicator roller 4 and friction roller 5 does not change.

Hierzu sind an der Gestellwand 7 Stützen 12 vorgesehen, in welchen Druckstücke 14 federnd angeordnet sind. Diese Stützen 12 und die Druckstücke sind dabei so angeordnet, daß sie auf die Lagerzapfen 10 und 11 drücken und die Auftragwalze 4 und die Reibwalze 5 gegeneinander drücken. Dabei wird das Spiel in den Lagerbohrungen 8 und 9 so verlagert, daß der Stoß direkt in die Gestellwand 7 geleitet wird. Der Achsabstand zwischen Auftragwalze 4 und Reibwalze 5 wird somit exakt festgelegt.For this purpose, supports 12 are provided on the frame wall, in which pressure pieces 14 are arranged resiliently. These supports 12 and the pressure pieces are arranged so that they press on the journals 10 and 11 and press the applicator roller 4 and the friction roller 5 against each other. The game is shifted in the bearing bores 8 and 9 so that the impact is passed directly into the frame wall 7. The center distance between applicator roller 4 and friction roller 5 is thus precisely defined.

Sollte sich der Stoß zwischen Reibwalze 5 und Schöpfwalze 6 auswirken ist eine Beeinflussung des Druckbildes nicht mehr möglich, da zwischen Auftragwalze 4 und Reibwalze 5 eine Verreibung stattfindet.If the impact between the friction roller 5 and the scoop roller 6 has an effect, it is no longer possible to influence the printed image, since rubbing takes place between the application roller 4 and the friction roller 5.
