Definitions
- the invention relates to a method and an apparatus for Color guidance in an offset printing machine according to the generic term of claims 1 and 2.
- the ink supply to a plate cylinder is carried out from an ink fountain and ink metering elements that interact with an ink fountain roller.
- the zonally metered ink on the ink fountain roller is preferably transferred via a lifting roller to a first inking roller and from there via a roller train formed by a number of rollers to the inking rollers set on the plate cylinder.
- An inking unit of this type is known from EP 0 280 957 A2 with a distributor roller arranged in a ink supply roller.
- the ink flow in the direction of the inking rollers is divided into two inking streams, also called inking strands, by two parallel partial roller rollers, so that when viewed in the direction of rotation of the plate cylinder, the front inking rollers can be inked with a first inking stream and the downstream inking rollers with a second inking stream.
- the predominant amount of ink is preferably fed to the front inking rollers, so that a front-heavy inking unit is present.
- Inks of offset printing machines often also have so-called Color flow separations through which the single drum one or more places interrupted (rollers switched off) can be. This is only for printing interruptions a change in the color layer thickness profile prevent continuous inking.
- the rollers are interrupted again at the start of printing juxtaposed so that the original color flow is restored.
- Such a device is for example known from EP 0 741 024 B1.
- the adjustable rollers can be turned on both sides in bearing levers stored and around the axis of a trained as a friction roller Distributor roller swiveling.
- Axial parallel to the distributor roller is a linearly movable coupled with a drive and adjusting means designed with a curved contour mounted on the frame side, with the bearing levers on the curve contour are supported.
- an inking unit with an inking unit roller
- an inking unit roller Known as a distribution roller
- the at least one portable stored calender roll in constant contact assigned.
- the calender roller flattens the ink film on the Uniform surface of the distribution roller evenly the ink flow to the downstream rollers (in the direction Inking rollers) interrupted periodically (clocked).
- the invention is based on the object of providing a method and a device of the type mentioned at the outset which, in particular, permit stable ink guidance in the inking unit and noticeably reduce the tendency to stenciling.
- the task is solved by the training features of claims 1 and 2. Further developments result from the dependent claims.
- stenciling is an error in Printing in which there is a structure of the printing form - in the printing direction offset - additionally depicted one or more times.
- a first advantage of the solution according to the invention is therefore in that especially with difficult printing forms and / or special printing inks, such as metallic inks or strong Fountain solution-absorbing inks, these irregularities avoided or at least when inking a printing form noticeably reduced.
- a second advantage is based on the fact that a distributor roller arranged in the roller train of an inking unit the color flow in printing or the planned color flow even before printing begins (when the machine is idle) is specifically influenced.
- the direction in the inking unit Amount of color fed to the printing form, in particular to the front inking rollers in the direction of rotation of the plate cylinder preferably depending on the printing form used or printing ink influenced.
- a second procedure the additional amount of ink according to the first procedure is reduced on the preferably two front inking rollers.
- the inking unit continues to be designed with a front load, only the amount of color that is otherwise added to the main ink stream according to the first procedure is reduced.
- a third procedure can be implemented in that the ink flow (main amount of ink) - starting from the distributor roller - is increasingly fed to the last two inking rollers in the direction of rotation of the plate cylinder, so that there is a rear-loaded inking unit.
- the front-heavy inking unit is the color flow to the front inking rollers in the direction of rotation of the plate cylinder for a defined period of time around the additionally added Amount of color, i.e. the total amount of color, increased (first procedure). Then - after one Roller changeover - the ink flow according to the second procedure (with the elimination of the first procedure additionally supplied amount of color) in the still front heavy Inking led.
- the inking unit is first operated in the second procedure in order to avoid over-inking on the printing material. Subsequently, ie when a specified speed is reached, the inking unit is operated in the first mode of operation in order to avoid possible stenciling or at least to significantly reduce it. If, according to the first procedure, an over-dyeing occurs in the printing operation, this problem can be solved by switching the inking unit to the second procedure during the printing operation.
- Figure 1 is an inking unit 3 for an offset printing press shown.
- the color is based on one with dosing elements interacting ink fountain in zones on an ink fountain roller 5 applied.
- the distributor roller 8 is preferably the second Tractor roller trained.
- the distributor roller 8 splits the seen in the ink flow direction Single drum roller and thus the color flow over two subordinate ones Branch rollers 9, 10 in two partial roller trains 23, 24. about the front inking roller 9 becomes ink on the third friction roller 13 and the - in the direction of rotation one with a blanket cylinder 2 seen in contact plate cylinder 1 - front (first two) inking rollers 11 of the inking unit 3 fed.
- the plate cylinder 1 carries one on the outer surface fixable printing form. Alternatively, is on the outer surface of the plate cylinder 1, a printing form can be produced, fixable and preferably erasable.
- the ink is fed from the distributor roller 8 (second friction roller) to an inking roller 12, preferably a bridge roller, and from there via the further (second, third and fourth) inking rollers 11, seen in the direction of rotation of the plate cylinder 1, to the plate cylinder 1 ,
- the last inking roller 11 in the direction of rotation of the plate cylinder 1 receives 14 ink from the adjacent, penultimate inking roller 11 via a fourth friction roller.
- the friction rollers 7, 13 and 14 and the distributor roller 8, which is designed as a friction roller, can be driven to rotate and axially oscillate.
- a dampening unit 4 is assigned to the inking unit 3 in the direction of rotation of the plate cylinder 1 for wet offset printing.
- the ink flow direction of the distributor roller 8 is the front one Sub-roller 23 and the rear partial roller 24 arranged downstream, the partial roller trains 23, 24 parallel to each other are arranged.
- the front partial roller train 23 is formed through the branch roller 9, the friction roller 13 and the two first inking rollers 11.
- the rear partial roller 24 is formed by the branch roller 10, the ink roller 12, the Rubbing roller 14 and the further inking rollers 11.
- Branch rollers 9, 10 are each end in a first and second bearing lever 16, 17 arranged.
- the bearing levers 16 carry the branch roller 10 and the bearing lever 17 carry the Branch roller 9.
- EP 0741 024 B1 known device used in the inking unit 3 and improved so that this device preferably in addition to the Color flow separation in the event of a possible print interruption can be used for color guidance within the inking unit.
- Each bearing lever 16, 17 is in the direction of the subordinate Rollers (ink flow direction), here friction roller 13 and ink roller or bridge roller 12, sprung.
- the bearing levers 16, 17 are individually with the branch roller 9 in each case or 10 or together with both branch rollers 9, 10 by one Axis 15 of the distributor roller 8 can be pivoted (FIG.
- the branch rollers 9, 10 are always with the Distribution roller 8 in contact and are with the neighboring ones Rollers (friction roller 13 and bridge roller 12) at nip points 21, 22 in or out of contact.
- the one gap 22 exists at the contact point (or separation point) of the branch roller. 9 and friction roller 13 and the further nip 21 is present the contact point (or separation point) of branch roller 10 and Bridge roller 12.
- cam supports 19, 20, preferably cam rollers, are arranged on the end of each bearing lever 16, 17.
- a cam carrier 20 is arranged on each first bearing lever 16 and a cam carrier 19 is arranged on every second bearing lever 17.

- the adjusting means 18 is preferably designed as an adjusting rod which is arranged axially parallel to the axis 15 and is mounted in the side frames.
- the setting means 18 has a curve contour on the circumference and the curve supports 19, 20 are in or out of engagement with this curve contour, depending on the respective axial position of the setting means 18.
- a drive for example a double-acting multi-position cylinder, is arranged at one end, with which several linear positions of the adjusting means 18 can be controlled.
- the drive is preferably coupled to a machine control and, depending on the desired procedure, can be activated when the printing machine is at a standstill and / or in printing mode.

Abstract
Description
Ein Farbwerk dieser Art ist aus EP 0 280 957 A2 mit einer in einem Farbe zuführenden Walzenzug angeordneten Verteilerwalze bekannt. Ab der Verteilerwalze wird der Farbfluss in Richtung der Farbauftragwalzen durch zwei parallele Teilwalzenzüge in zwei Farbströme, auch Farbstränge genannt, aufgeteilt, so dass in Drehrichtung des Plattenzylinders gesehen die vorderen Farbauftragwalzen mit einem ersten Farbstrom und die nachgeordneten Farbauftragwalzen mit einem zweiten Farbstrom einfärbbar sind. Dabei wird bevorzugt die überwiegende Menge an Farbe an die vorderen Farbauftragwalzen zugeführt, so dass ein vorderlastiges Farbwerk vorliegt.
Gelöst wird die Aufgabe durch die Ausbildungsmerkmale von Anspruch 1 und 2. Weiterbildungen ergeben sich aus den abhängigen Ansprüchen.
Alternativ ist eine dritte Verfahrensweise realisierbar, indem der Farbfluss (Hauptmenge an Farbe) - ausgehend von der Verteilerwalze - verstärkt auf die in Drehrichtung des Plattenzylinders beiden letzten Farbauftragwalzen zugeführt wird, so dass ein hinterlastiges Farbwerk vorliegt.
Das Umstellen des Farbflusses ab der Verteilerwalze von der ersten in die zweite Verfahrensweise bzw. umgekehrt ist im Maschinenstillstand sowie während des Druckbetriebes durchführbar.
Sollte gemäß der ersten Verfahrensweise im Druckbetrieb ein Überfärben auftreten, so ist diese Problem lösbar, indem das Farbwerk während des Druckbetriebes auf die zweiten Verfahrensweise umgestellt wird.
- Fig. 1
- ein Farbwerk einer Offsetdruckmaschine,
- Fig. 2
- eine umstellbare Walzenanordnung,
- Fig. 3
- ein Stellmittel in erster Umstellposition,
- Fig. 4
- das Stellmittel gem. Fig. 3 in zweiter Umstellposition.
Für den Naß-Offsetdruck ist in Drehrichtung des Plattenzylinders 1 dem Farbwerk 3 ein Feuchtwerk 4 zugeordnet.
Den Kurventrägern 19, 20 ist ein gestellseitig gelagertes, axial bewegbares Stellmittel 18 zugeordnet. Bevorzugt ist das Stellmittel 18 als eine achsparallel zur Achse 15 angeordnete, in den Seitengestellen gelagerte Stellstange ausgebildet. Das Stellmittel 18 weist umfangsseitig eine Kurvenkontur auf und die Kurventräger 19, 20 sind mit dieser Kurvenkontur - abhängig von der jeweiligen axialen Position des Stellmittels 18 - in oder außer Eingriff. Zur axialen Bewegung des Stellmittels 18 ist an einem Ende ein gestellfester Antrieb (nicht gezeigt), beispielsweise ein doppeltwirkender Mehrstellungszylinder, angeordnet mit dem mehrere lineare Positionen des Stellmittels 18 ansteuerbar sind. Der Antrieb ist bevorzugt mit einer Maschinensteuerung gekoppelt und ist je nach gewünschter Verfahrensweise im Stillstand der Druckmaschine und/oder im Druckbetrieb aktivierbar. Bei Ausbildung der Vorrichtung für die Farbstromtrennung bei einer Druckunterbrechung und zur Farbführung im Farbwerk 3 ist die Kurvenkontur des Stellmittels 18 mit Kurvengesetzen für eine Farbstromtrennung und für die Farbführung gemäß der Erfindung ausgelegt. Zumindest weist die Kurvenkontur des Stellmittels 18 ein Kurvengesetz auf, wonach zumindest die Kurventräger 20 der die Abzweigwalze 10 tragenden Lagerhebel 16 bei axialer Betätigung des Stellmittels 18 mittels Antrieb mit der Kurvenkontur in Eingriff bringbar sind, derart, dass die Abzweigwalze 10 entgegen einer in Farbflussrichtung zur Druckform wirkenden Federkraft um die Achse 15 der Verteilerwalze 8 schwenkbar ist. Dadurch ist die Abzweigwalze 10 an der Spaltstelle 21 zu der in Farbflussrichtung nachgeordneten Farbwalze 12 trennbar, wobei die Abzweigwalze 10 mit der Verteilerwalze 8 in ständigem Kontakt ist. Durch erneute Betätigung des Stellmittels 18 in eine weitere Position wird der Kontakt von Kurventräger 20 mit der Kurvenkontur des Stellmittels 18 aufgehoben (außer eingriff). Da weiterhin die Federkraft anliegt, wird die Abzweigwalze 20 wieder an die benachbarte Farbwalze 12 angestellt und schließt somit die Spaltstelle 21.
Dagegen ist die Abzweigwalze 10 von der benachbarten Farbwalze 12 an der Spaltstelle 21 getrennt (Fig. 2 , Position der Abzweigwalze 10 in voller Linie). Die Trennung ist dadurch realisierbar, indem die die Abzweigwalze 10 tragenden Lagerhebel 16 gegen die anliegende Federkraft durch die Kurvenkontur des Stellmittels 18 um die Achse 15 der Verteilerwalze 8 verschwenkt sind. Die axiale Betätigung des Stellmittels 18 erfolgt bevorzugt mittels eines ansteuerbaren, doppeltwirkenden Mehstellungszylinders. Diese Walzenposition im Farbwalzenzug entspricht der eingangs beschriebenen ersten Verfahrensweise, bei der über die Spaltstelle 22 eine zusätzliche Menge, d.h. die Gesamtmenge, an Farbe von der Verteilerwalze 8 auf die beiden in Drehrichtung des Plattenzylinders 1 vorderen Farbauftragwalzen 11 zugeführt wird.
In dieser Position sind die Abzweigwalzen 9, 10 an den Spaltstellen 21, 22 mit der benachbarten Reiberwalze 13 (Spaltstelle 22) und Farbwalze 12 (Spaltstelle 21) durch die angefederten Lagerhebel 16, 17 in Kontakt. In Fig. 2 entspricht dies an der Spaltstelle 21 der Position der Abzweigwalze 10 in Strich-Punkt-Darstellung. Diese Walzenposition im Farbwalzenzug entspricht der eingangs beschriebenen zweiten Verfahrenweise, bei der die ursprünglich zusätzlich zugeführte Menge an Farbe (erste Verfahrensweise) reduziert ist. Die Farbführung erfolgt ab der Verteilerwalze 8 zweisträngig zum Plattenzylinder 1, nämlich:
- über den vorderen Teilwalzenzug 23, gebildet aus Farbwalze
9, Reiberwalze 13
und der ersten und zweiten Farbauftragwalze 11 und - über den hinteren Teilwalzenzug 24, gebildet aus Farbwalze
10, Brückenwalze
12 und der dritten bzw. vierten Farbauftragwalze 11.
