Abstract

The roller is for use in printing presses, spreading liq. or ink by friction, performing a rotary and an axial movement and cooperating with an applicating with an application or wiping roller, from which the rotary motion is derived by friction of the peripheral surfaces. The spreading roller is of very small dia., and is mounted on levers secured to the bearing trunnions of a friction cylinder. The levers can be coupled to the next friction cylinder or the one beyond it working in the opposite direction.

Description

Verreibwalze in DruckmaschinenDistribution roller in printing machines

Anwendungsgebiet der rfindung Die Erfindung betrifft eine Verreibwalze in Druckmaschinen zum Verreiben von Feuchtflüssigkeit oder Farbe.Field of application of the invention The invention relates to a distribution roller in printing machines for rubbing dampening liquid or paint.

Charakteristik der bekannt;en technischen Lösungen Es sind verschiedene friktionsangetriebene Verreibwalzen die mit Auftragwalzen zusammenwirken bekannt geworden, bei denen durch ein im Walzeninneren untergebrachtes Getriebe eine axiale Hin- und Herbewegung erzeugt wird (DE-OS 1 611 196; DE-%S 2 045 717).Characteristics of the known technical solutions There are various friction-driven distribution rollers that interact with applicator rollers are known become, in which an axial gearbox housed inside the roll Back and forth movement is generated (DE-OS 1 611 196; DE-% S 2 045 717).

Diese Verreibwalzen haben den gemeinsamen Nachteil, daß sie wegen des relativ großen Durchmessers die erforderliche Reibleistung nicht erbringen. Line Verkleinerung des Durchmessers ist aber nicht möglich, weil das Getriebe im Walzenkörper untergebracht werden muß. Darüber hinaus neigen die Verreibwalzen zu ungleicher Schlupfverhältnissen, wodurch der aufgetragene Farbfilm Schichtdickenschwankungen aufweist.These Verreibwalzen have the common disadvantage that they because of the relatively large diameter do not provide the necessary frictional power. Line reduction of the diameter is not possible because the gear is in Roll body must be accommodated. In addition, the distribution rollers tend to unequal slip ratios, whereby the applied paint film layer thickness fluctuations having.

Verreibwalzen dieser Bauart haben einen hohen Teileaufwand und sind demzufolge sehr teuer.Distribution rollers of this type have a high number of parts and are therefore very expensive.

Bei einer anderen Vorrichtung (DE-OS 2 052 806) arbeitet eine Auftragwalze mit zwei Verreibwalzen zusammen, die eine hin- und hergehende Bewegung ausführt. Beide Verreibwalzen besitzen je ein Rakel zum Abstreifen der Farbe.In another device (DE-OS 2 052 806) an applicator roller works with two distribution rollers that perform a reciprocating motion. Both distribution rollers each have a squeegee to strip off the ink.

Diese Verreibwalzen benötigen zur Erzeugung der axialen Bewegung ein separates Getriebe. Der Teileumfang sowie auch die Kosten werden dadurch wesentlich erhöht.These distribution rollers require a to generate the axial movement separate gear. The scope of parts as well as the costs become significant as a result elevated.

Zicl der Erfindung Ziel der Erlindung ist es, cine Verreibwalze zum Verreiben von Feuchtflüssigkeit und Farbe zu entwickcln, mit der die schädlichen Auswirkungen der Längs- und @uerschablonen auf dem Druckbild beseitigt werden.Zicl of the invention The aim of the invention is a distribution roller for Rub in the dampened liquid and paint to develop the harmful The effects of the longitudinal and outer stencils on the print image are eliminated.

Wesen der Erfindung Der Erfindung liegt die Aufgabe zu Grunde, cine Vor-Teihwalse zu schaffen, die eine hohe Vorreibleistung hat, eine bin- und her@chande Bewegung ausfübrt, cinfach und billig her@ellbar ist und nuf dine Ad@ragnwalze, votzw@sweist der letsten anstellbar ist.Essence of the Invention The invention is based on the object, cine To create Vor-Teihwalse, which has a high pre-friction performance, a bin- und her @ chande Executes movement, is easy and cheap to manufacture and only uses an Ad @ ragn roller, votzw @ s shows the last one is employable.

Erfindungsgemäß wird dies conderch errcicht, indem die Vorreibwalze einen sehr kleinen Surchnesser hat und in Ecbeln gelagr@rt ist, die auf den Zapfen 2inec Keibzylinders befestigt sind.According to the invention, this is achieved conderch by the drive roller has a very small Surchnesser and is gelagr @ rt in ecbel that is on the cone 2inec key cylinders are attached.

Die die Verreibvalze aufnehmenden Hebel können dabei mit dem nächsten Reibzylinder, oder dem zu diesem entgegengesetzt arbcitenden übernächsten Roibzylinder verbunden sein.The levers receiving the Verreibwalze can with the next Distribution cylinder, or the next but one Roib cylinder working in the opposite direction be connected.

Ausführungsbeispiel Die Erfindung soll nachstchend an einem Ausführungsbeispiel näher erläutert werden.Exemplary embodiment The invention is intended to be based on an exemplary embodiment are explained in more detail.

In der zugehörigen Zechnung zeigen : Fig. 1 : eine Scitenansicht eines Teiles des Farbwerkes Fig. 2 : eine Draufsicht auf Reibzylinder und Vorrcibwalze Aus Fig. 1 geht hervor, daß die auftragwalze 1 mit dem Formzylinder 2 und mit dem Reibzylinder 3 in Berührung ist. Die Verreibwalze 4 ist mit der Auftragwalze 1 in ständiger Berührung und wird durch diese in Drehung versetzt. Auf den Zapfen 5, 6 des Reibzylinders 3 sind die Hesel 7, 8 befestigt, die die Vorzeibwalze 4 tragen.The associated drawings show: FIG. 1: a scan view of a Part of the inking unit Fig. 2: a plan view of the distribution cylinder and Vorrcibwalze the end Fig. 1 shows that the application roller 1 with the forme cylinder 2 and with the distribution cylinder 3 is in contact. The distribution roller 4 is in constant contact with the applicator roller 1 and is set in rotation by this. On the pin 5, 6 of the distribution cylinder 3 the Hesel 7, 8 are attached, which carry the Vorzeibwalze 4.

Da die Zapfen 5, 6 das Reibzylinders 3 fest mit dem Zylinderkörper 9 verbunden sind, und demzufolge mitdrehen, ist es erforderlich, daß die Hebel 7, 8 über die kälzloyer 10 mit den Zapfen verbun@@n werden. Die hin- und hergchende Bewegung des Reibzylinders wird somit über die Wälzlager 10 und die Habel 7, 8 auf die Verreibwalze 4 übertragen.Since the pin 5, 6, the distribution cylinder 3 fixed to the cylinder body 9 are connected, and therefore rotate with it, it is necessary that the lever 7, 8 can be verbun @@ n via the kälzloyer 10 with the tenons. The back and forth Movement of the distribution cylinder is thus based on the roller bearings 10 and the handle 7, 8 the distribution roller 4 transferred.

Die die Verreibwalze 4 aufnchmenden Hebel 7, 8 können auch so ausgebildet werden, daß sie mit dem übernäcnsten Reihzylinder 11, der zum nächsten keibzylinder 3 zutgegengesetzt srbeitet, verbunden sind. Das Sie hin-und hergehende Bewegung der Reibzylinder 3, 11 orzeugende Getriebe ist bakannt und wird hier nicht näher beschrieben.The levers 7, 8 which take up the distribution roller 4 can also be designed in this way that they are connected to the next row cylinder 11, the one to the next key cylinder 3 works opposite, are connected. That you move back and forth the distribution cylinder 3, 11 orgenerating transmission is known and is not discussed here described.
