Abstract
Description
Die Erfindung betrifft ein Farbwerk für eine Bogenoffsetdruckmaschine gemäß dem Oberbegriff von Anspruch 1.The invention relates to an inking unit for a sheetfed offset printing press according to the preamble of claim 1.
Bei Bogenoffsetdruckmaschinen wird die zu verdruckende Farbe von einer Farbkastenwalze über eine Heberwalze und eine Anzahl von Farbwalzen auf die Druckform aufgebracht und von dort über einen Offsetzylinder (Gummituchzylinder) auf den Bedruckstoff aufgetragen. Die der Heberwalze nachgeordnete Farbwalze ist dabei meist als Reiberwalze ausgebildet (erster Reiber) und führt einstellbare periodische Bewegungen aus. In dem Walzenzug zwischen diesem ersten Reiber und den Farbauftragwalzen können weitere Reiberwalzen vorgesehen sein. Diese Reiberwalzen weisen dabei sowohl für die Changier- als auch die Rotationsbewegung einen Antrieb auf. Dieser Antrieb kann dabei von der Bewegung des Druckwerkes (Plattenzylinder) abgeleitet sein und aus einem Räderzug bestehen. Ein Farbwerk der obengenannten Art ist dabei insbesondere durch die Maschine der Baureihe R 700 der MAN Roland Druckmaschinen AG bekannt.In sheet-fed offset printing machines, the ink to be printed is fed by an ink fountain roller via a lifter roller and a number of ink rollers on the Printing form applied and from there via an offset cylinder (Blanket cylinder) applied to the substrate. The lifter roller downstream ink roller is usually designed as a friction roller (first Reiber) and performs adjustable periodic movements. In the single drum between this first grater and the inking rollers, further grater rollers can be used be provided. These friction rollers show both for the Changier- as well as the rotational movement a drive. This drive can be derived from the movement of the printing unit (plate cylinder) and consist of a gear train. An inking unit of the type mentioned above is included especially through the machine of the R 700 series from MAN Roland Druckmaschinen AG known.
Die weiteren Walzen in dem oben geschilderten Walzenzug weisen keinen eigenen Antrieb auf, d.h. deren Rotationsbewegung erfolgt über Friktion von den weiteren Farbwalzen (den Reibern) her. Entsprechend der Zügigkeit der zu verdruckenden Farbe entsteht dabei ein mehr oder weniger großer Schlupf zwischen der treibenden Walze und der entsprechend angetriebenen Farbwalze. Dieser Schlupf wird zudem durch die ohnehin vorhandenen Lagerkräfte vergrößert und führt zu einer Verringerung des Farbflußes und somit zu einer Abnahme der auf den Bedruckstoff aufgetragenen Farbschichtdicke (Farbdichte). Neben den Walzen, welche einen eigenen Antrieb aufweisen (Reiber) und den direkt von diesen angetriebenen Walzen weisen Farbwerke der oben geschilderten Art zusätzlich auch Zwischenwalzen auf, welche keinen eigenen Antrieb besitzen und die nur mit nicht angetriebenen Farbwalzen in Kontakt stehen. Bei diesen Walzen nimmt der Schlupf zu höheren Maschinendrehzahlen hin große Werte an, d.h. bei hohen Maschinendrehzahlen (Druckgeschwindigkeiten) kann es ohne geeignete Gegenmaßnahmen zu einem deutlichen Farbabfall (Abnahme der Farbdichte auf dem Bedruckstoff) kommen.The other rollers in the single drum roller described above do not have their own Drive on, i.e. their rotational movement takes place via friction from the others Ink rollers (the graters). According to the speed of printing Color creates a more or less large slip between the driving roller and the correspondingly driven ink roller. This Slip is also increased by the existing bearing forces and leads to a reduction in the color flow and thus to a decrease in the ink layer thickness (ink density) applied. In addition to the rollers, which have their own drive (friction) and that directly from them driven rollers also have inking units of the type described above also intermediate rolls, which do not have their own drive and which only be in contact with non-driven ink rollers. With these rollers takes the slip towards higher machine speeds indicates large values, i.e. at high Machine speeds (printing speeds) can be done without suitable countermeasures to a significant drop in color (decrease in color density the substrate).
Aus der DE 195 29 204 A1 ist ein gattungsgemäßes Farbwerk der zuvorstehend beschriebenen Art bekannt.From DE 195 29 204 A1, a generic inking unit is the above described type known.
Aus der DE 195 20 841 A1 ist ein Farbwerk für ein Offsetdruckwerk nebst einem Verfahren zum Einfärben und Feuchten einer Druckform bekannt. Eine Farb-/Feuchtauftragwalze wird hinsichtlich ihrer Umfangsgeschwindigkeit mit einer Differenz zu der des Formzylinders betrieben. Auch weitere Reiber, welche insbesondere mit Elektromotoren treibbar sind, können Differenzgeschwindigkeiten aufweisen.DE 195 20 841 A1 discloses an inking unit for an offset printing unit, in addition to one Process for inking and dampening a printing plate is known. An ink / dampening roller becomes with a difference in their peripheral speed operated to that of the forme cylinder. Also other graters, which in particular with Electric motors can be driven, can have differential speeds.
Aufgabe der vorliegenden Erfindung ist es daher, ein Farbwerk gemäß dem Oberbegriff von Anspruch 1 derartig weiterzubilden, so daß es bei höheren Maschinengeschwindigkeiten nicht zu einem Farbabfall kommt und ferner auch Änderungen in der Druckgeschwindigkeit (Maschinengeschwindigkeit) keine negativen Auswirkungen auf die Färbung bewirken.The object of the present invention is therefore to provide an inking unit according to the Develop the preamble of claim 1 such that it is at higher machine speeds there is no color drop and furthermore Changes in print speed (machine speed) none cause negative effects on the coloring.
Gelöst wird diese Aufgabe durch die kennzeichnenden Merkmale von Anspruch 1. Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen.This object is achieved by the characterizing features of claim 1. Further developments of the invention result from the subclaims.
Gemäß der Erfindung ist vorgesehen, daß das Farbwerk neben einer Anzahl einen eigenen Antrieb aufweisender Walzen ausschließlich Walzen aufweist, die über Reibkontakt direkt von wenigstens einer mit einem Antrieb versehenen Walze getrieben werden. Mit anderen Worten bedeutet dies, daß das Farbwerk keine Walzen aufweist, welche nur indirekt von mit einem eigenen Antrieb versehenen Walzen getrieben werden. Die über keinen eigenen Antrieb verfügenden Walzen stehen daher zumindest mit einer einen eigenen Antrieb aufweisenden Walze in Kontakt.According to the invention it is provided that the inking unit in addition to a number has its own drive of rollers only rollers that via frictional contact directly from at least one provided with a drive Roller are driven. In other words, this means that the inking unit has no rollers which are only indirectly provided with their own drive Rolls are driven. Those that do not have their own drive Rollers are therefore at least with their own drive Roller in contact.
Gemäß der vorliegenden Erfindung sind dabei folgende Konstellationen möglich: Eine keinen eigenen Antrieb aufweisende Walze steht mit zwei einen eigenen Antrieb aufweisenden Walzen in Kontakt, oder eine keinen eigenen Antrieb aufweisende Walze steht mit einer einen eigenen Antrieb aufweisenden Walze in Kontakt, ferner mit einer ebenfalls keinen Antrieb aufweisenden Walze, die jedoch wiederum mit einer einen eigenen Antrieb aufweisenden Walze zusammenwirkt.According to the present invention, the following constellations are possible: A roller that does not have its own drive has two of its own Drive rollers in contact, or a non-own drive The roller is in a roller with its own drive Contact, also with a roller that also has no drive, but that in turn cooperates with a roller having its own drive.
Der Antrieb für die Walzen des erfindungsgemäßen Farbwerkes kann dabei über einen eigenen Räderzug direkt vom Druckwerk (Plattenzylinder) her erfolgen, wobei es möglich ist, an bestimmten Stellen einen festen Schlupf, d.h. eine vorgesehene Drehzahldifferenz zu erzeugen. Walzen mit einem vom Druckwerk her abgeleiteten Antrieb sind dabei vorzugsweise als Reibwalzen ausgebildet, bei denen der Antrieb sowohl die Changier- als auch die Rotationsbewegung erzeugt.The drive for the rollers of the inking unit according to the invention can your own wheel train directly from the printing unit (plate cylinder), it is possible to have a fixed slip at certain points, i.e. an intended To generate speed difference. Rolling with one from the printing unit derived drive are preferably designed as friction rollers, at which the drive generates both the traversing and the rotating movement.
Weiterhin kann vorgesehen sein, daß bestimmte Zwischenwalzen mittels einem eigenen steuerbaren Antrieb versehen sind, wobei die dem Antrieb vorgeordnete Steuerung ein Drehzahlsignal der Maschine bzw. des Druckwerkes erhält. Die Bestromung der Antriebe dieser Walzen erfolgt in der Weise, daß die Walzen die für die vorliegende Druckgeschwindigkeit vorgesehenen Drehzahlwerte fahren. So ist es möglich, die Zwischenwalzen mit einer derartigen Drehzahl anzutreiben, so daß deren Umfangsgeschwindigkeit gleich der der benachbarten Walzen ist. Auch ist es-möglich, vorgegebene Schlupfwerte bzw. Drehzahldifferenzen einzustellen, um so eine zusätzliche Dosier- bzw. Farbverteilungsmöglichkeit zu erhalten.Furthermore, it can be provided that certain intermediate rolls by means of a own controllable drive are provided, the upstream of the drive Control receives a speed signal from the machine or the printing unit. The Powering the drives of these rollers takes place in such a way that the rollers Drive the speed values provided for the current printing speed. So it is possible to drive the intermediate rolls at such a speed, so that their peripheral speed is equal to that of the adjacent rollers. It is also possible to set predetermined slip values or speed differences, in order to obtain an additional dosing or color distribution option.
Der Vorteil eines Farbwerkes gemäß Erfindung liegt insbesondere darin, daß der Farbabfall bei hohen Druckgeschwindigkeiten nicht mehr in der sonst zu beobachtenden deutlichen Weise auftreten kann. Auch Veränderungen der Drehzahl der Maschine (Druckgeschwindigkeit) wirken sich nicht mehr als kurzzeitig deutlich zu beobachtende Färbungsveränderungen aus. Diese werden sonst dadurch hervorgerufen, daß bei einer Drehzahlveränderung die nur indirekt getriebenen Walzen entsprechend der Reibungsverhältnisse nur allmählich den entsprechenden Umfangsgeschwindigkeiten folgen. Ferner können bei einem Walzenwaschvorgang mit in den Walzenzug eingebrachtem Wasch- bzw. Lösungsmittel die Zwischenwalzen nicht mehr blockieren und so das Waschergebnis verschlechtern. The advantage of an inking unit according to the invention is in particular that the Color drop at high printing speeds no longer in the otherwise observable can occur clearly. Also changes in the speed of the The machine (printing speed) no longer has a significant effect for a short time observing color changes. Otherwise these are caused by that when the speed changes, the rollers are driven only indirectly according to the friction conditions only gradually the corresponding peripheral speeds consequences. Furthermore, in a roller washing process the intermediate rollers with washing or solvent introduced into the roller train no longer block and worsen the washing result.

über Farbwalzen 5, 6, 7 zu einem zweiten Reiber 8 transportiert und durch
die entsprechend vielen Spaltvorgänge zu einem dünnen Farbfilm ausgewalzt. Mit
dem zweiten Reiber 8 stehen zwei weitere Farbwalzen 9, 10 in Kontakt, so daß
der Farbfilm auf dem Reiber 8 auf zwei Wegen zu den mit dem Plattenzylinder 18
in Kontakt stehenden Farbauftragwalzen 14, 15, 16, 17 gelangt. Zum einen erfolgt
der Farbtransport über die Farbwalze 9 und eine dieser nachgeordneten Farbwalze
11 direkt zu den Farbauftragwalzen 15, 16. Die letzte Farbauftragwalze 14
wird dabei über einen weiteren Reiber 13, der mit der Farbauftragwalze 15 in
Kontakt steht, mit Farbe versorgt. Ein zweiter Farbfluß erfolgt vom Reiber 8 über
eine Farbwalze 10 und einen weiteren Reiber 12 zu den Farbauftragwalzen 16,
17. Die Feuchtauftragwalze sowie die weiteren Walzen des Feuchtwerkes sind in
der Figur angedeutet.The amount of ink applied by the squeegee roller 3 to the grater 4 is then
transported via
Die Reiber 4, 8, 12, 13 weisen einen eigenen und vorzugsweise vom Druckwerk
her abgeleiteten Antrieb auf, vermittels dem diese Walzen sowohl in Rotationsals
auch in eine vorzugsweise einstellbare Changierbewegung versetzt werden. The
Weiterhin weisen die Farbwalzen 6 und 11 ebenfalls einen eigenen Antrieb auf,
wobei die Drehzeit dieser Walzen derartig einstellbar ist, so daß deren Umfangsgeschwindigkeiten
gleich oder entsprechend einem gewünschten Wert unterschiedlich
zu den Umfangsgeschwindigkeiten der mit diesen Walzen in Kontakt
stehenden Walzen ist.Furthermore, the
Mit dem Reiber 13 wirkt bedarfsweise eine Walzenwaschvorrichtung 19 in Form
einer Auffangwanne und ein an den Reiber 13 anstellbares Rakel zusammen. Für
