Abstract

PCT No. PCT/CH88/00053 Sec. 371 Date Nov. 2, 1988 Sec. 102(e) Date Nov. 2, 1988 PCT Filed Mar. 3, 1988 PCT Pub. No. WO88/06523 PCT Pub. Date Sep. 7, 1988.A movable lifter roller (6) used for transferring the ink from an inking roller (8) to a brayer roller (5) is subdivided into a number of sections (6'). Each lifter-roller section (6') is pivoted on a respective two-armed lever (22). All levers (22) are pivotably disposed on a common axle (28) in such a way that the lifter-roller sections (6') normally rest against the brayer roller (5) and, in the activated state for picking up ink, rest against the inking roller (8). After the return into the position previously assumed, the ink picked up is transferred to the brayer roller (5). For putting the lifter-roller sections (6') into the activated state, there is associated with each individual lifter-roller section a respective electromagnet (31) which a lug (30) of the lever (22) serves as an anchor. All electromagnets 31 are rigidly fastened to a stationary support (33). Each electromagnet (31) is excited individually by means of a controller, the duration of the excitement being dependent upon the ink-density measured value belonging to the respective area. With the inking device thus designed, existing inking devices can be used, it merely being necessary to exchange the inkwell for changing the ink.

Description

Die Erfindung betrifft ein Farbwerk gemäss dem Oberbegriff des Patentanspruches 1.The invention relates to an inking unit according to the preamble of claim 1.

In der europäischen Patentschrift mit der Veröffentlichungsnummer 113 905 ist ein Verfahren zum Einstellen des Farbauftrages in einem Farbkasten beschrieben. Der bekannte Farbkasten weist eine Farbwalze und ein mit dieser zusammenarbeitendes, in einzelne beschnitte unterteiltes Rakel auf. Jedem Rakelabschnitt ist eine Einstellschraube und ein durch diese betätigbares Winkelstück zum Verändern des Abstandes zwischen dem Rakelende und der Farbwalze zugeordnet. Durch Betätigen der Einstellschrauben kann die Dicke der Farbschicht auf der Farbwalze und damit die Farbdichte auf dem bedruckten Papierbogen abschnittsweise eingestellt werden. Bei diesem bekannten Farbwerk ist es wünschenswert, die Einstellgenauigkeit des Farbauftrages zu verbessern.European Patent Publication No. 113 905 describes a method for setting the color application in an ink fountain. The known ink fountain has an inking roller and a doctor blade which cooperates with it and is divided into individual trimmings. Each squeegee section is assigned an adjusting screw and an angle piece which can be actuated by it for changing the distance between the squeegee end and the inking roller. The thickness of the ink layer on the ink roller and thus the ink density on the printed paper sheet can be adjusted in sections by actuating the adjusting screws. In this known inking unit, it is desirable to improve the setting accuracy of the ink application.

In der europäischen Patentanmeldung mit der Veröffentlichungsnummer 131 104 ist eine Farbdosiereinrichtung für Buch- und Offsetdruckmaschinen offenbart. Die Uebertragung der Farbe erfolgt von einem Farbkasten über eine Farbkastenwalze zu einer Uebertragwalze mittels zwei Reihen von Farbheberscheiben. Jede dieser Farbheberscheiben ist mittels eines Elektromagneten zwischen einer Anlage an der Uebertragwalze oder einer Anlage an der Farbkastenwalze hin und her schwenkbar. Je nach Dauer der Anlage an der Farbkastenwalze kann die von der letzteren an die Heberscheibe abgegebene Farbmenge bestimmt werden. Gegenüber dem obgenannten Verfahren ist es mit dieser Einrichtung prinzipiell möglich, die Einstellgenauigkeit des Farbauftrages zu verbessern. Es ist in diesem Dokument jedoch keine eigentliche Steuerung offenbart, obschon deren Ausführungsart und Funktionsweise für die Genauigkeit des Farbauftrages und die Reproduzierbarkeit des letzteren wesentlich ist.A color metering device for book and offset printing machines is disclosed in European patent application with publication number 131 104. The ink is transferred from an ink fountain via an ink fountain roller to a transfer roller by means of two rows of ink lifter disks. Each of these ink-lifting disks can be swiveled back and forth by means of an electromagnet between a system on the transfer roller or a system on the ink fountain roller. Depending on the duration of the system on the ink fountain roller, the amount of ink delivered by the latter to the lifting disk can be determined. Compared to the above-mentioned method, it is possible in principle with this device to improve the setting accuracy of the paint application. No actual control is disclosed in this document, however Design and mode of operation is essential for the accuracy of the color application and the reproducibility of the latter.

Eine solche Steuereinrichtung ist beispielsweise in der US-Patentschrift 4 402 263 gezeigt. Die Farbübertragung von einer Farbwalze an eine Reiberwalze geschieht mittels nebeneinander angeordneten Heberscheiben, deren Mantelflächen im wesentlichen aus zwei schwenkbaren und radial verstellbaren Backen gebildet sind, wobei je nach Stellung dieser Backen die Auflagedauer an der Farbwalze und an der Reiberwalze einstellbar ist. Jeder dieser Heberscheiben ist ein Verstellmechanismus, der einen Elektromotor, ein Schneckengetriebe sowie ein Verstellgestänge umfasst, zugeordnet. Jeder Elektromotor wird von je einer Farbdichtemesseinrichtung gesteuert. Mit dieser Einrichtung ist die zu übertragende Farbmenge für jede der Heberscheiben automatisch steuerbar. Der technische Aufwand dazu ist jedoch beträchtlich. Zudem ist eine hohe Präzision in den einzelnen mechanischen Teilen von jeder der Heberscheiben und jedem der zugeordneten Antriebe erforderlich, wenn eine entsprechende Genauigkeit erreicht werden soll.Such a control device is shown, for example, in US Pat. No. 4,402,263. The ink transfer from an inking roller to a friction roller takes place by means of lifting disks arranged side by side, the lateral surfaces of which are essentially formed from two swiveling and radially adjustable jaws, the contact time on the inking roller and on the friction roller being adjustable depending on the position of these jaws. An adjustment mechanism, which comprises an electric motor, a worm gear and an adjustment linkage, is assigned to each of these lifting disks. Each electric motor is controlled by a color density measuring device. With this device, the amount of paint to be transferred can be automatically controlled for each of the lifting discs. However, the technical effort involved is considerable. In addition, high precision in the individual mechanical parts of each of the lifting disks and each of the associated drives is required if a corresponding accuracy is to be achieved.

Es ist deshalb die Aufgabe der vorliegenden Erfindung, ein Farbwerk zu schaffen, bei dem der Farbauftrag sehr fein regelbar ist, wobei mit der Erfindung auch eine wesentliche Vereinfachung gegenüber dem bekannten Stand der Technik erreicht werden soll. Da die Erfindung insbesondere Andruckmaschinen betrifft, ist es besonders vorteilhaft, wenn die Farbe im Farbwerk rasch auswechselbar ist.It is therefore the object of the present invention to provide an inking unit in which the ink application can be regulated very finely, with the invention also being intended to achieve a significant simplification compared to the known prior art. Since the invention relates in particular to presses, it is particularly advantageous if the ink in the inking unit can be exchanged quickly.

Das erfindungsgemässe Farbwerk ist durch die im kennzeichnenden Teil des Patentanspruches 1 angeführten Merkmale gekennzeichnet.The inking unit according to the invention is characterized by the features stated in the characterizing part of patent claim 1.

Der Erfindungsgegenstand ist nachstehend mit Bezugnahme auf die Zeichnung beispielsweise näher erläutert. Es zeigen

  • Fig. 2 einen Teil einer Heberwalze des Farbwerkes gemäss der Fig. 1 und
  • Fig. 3 das Blockschema einer Anlage zum Messen und Einstellen der Farbdichtewerte eines Druckbogens.
The subject matter of the invention is explained in more detail below with reference to the drawing, for example. It demonstrate
  • 1 shows a cross section through an embodiment of the inking unit according to the invention, the section plane being located between the side wall (not shown) and the inking unit,
  • Fig. 2 shows a part of a lifting roller of the inking unit according to FIGS. 1 and
  • 3 shows the block diagram of a system for measuring and setting the color density values of a printed sheet.

Die Fig. 1 zeigt den Querschnitt eines Eckbereiches eines Farbwerkes 1 einer Flachandruckpresse, von dem nur die eine Seitenwand 2 sichtbar ist. Das Farbwerk 1 umfasst eine Auftragwalze 3, eine Vorwalze 4, eine Reiberwalze 5, eine Heberwalze 6 und einen Farbkasten 7. Im Farbkasten 7 sind eine Farbwalze 8 drehbar und ein Rakel 9 verstellbar angeordnet. Auf der Oberseite des Farbkastens 7 ist ein Winkelstück 10 befestigt, dessen abgewinkeltes Ende 11 mit der benachbarten Wand 12 des Farbkastens 7 eine Nut 13 bildet, die nach unten offen ist. Zwischen der in der Fig. 1 sichtbaren Seitenwand 2 und der nicht sichtbaren Seitenwand des Farbwerkes 1 erstreckt sich ein Stab 14. Der Farbkasten 7 ist so in das Farbwerk 1 eingesetzt, dass sich der Stab 14 in der Nut 13 befindet. Der Boden 15 des Farbkastens 7 stützt sich auf wenigstens zwei Stellschrauben 16 ab, welche in Ansätze 17 des Farbkastens 1 eingeschraubt sind.Fig. 1 shows the cross section of a corner area of an inking unit 1 of a flat printing press, of which only one side wall 2 is visible. The inking unit 1 comprises an applicator roller 3, a preliminary roller 4, a friction roller 5, a siphon roller 6 and an ink fountain 7. In the ink fountain 7, an ink roller 8 is rotatable and a doctor blade 9 is arranged to be adjustable. On the top of the ink fountain 7, an angle piece 10 is fastened, the angled end 11 of which forms a groove 13 with the adjacent wall 12 of the ink fountain 7, which groove is open at the bottom. A rod 14 extends between the side wall 2 visible in FIG. 1 and the non-visible side wall of the inking unit 1. The ink fountain 7 is inserted into the inking unit 1 such that the rod 14 is located in the groove 13. The bottom 15 of the ink fountain 7 is supported on at least two set screws 16, which are screwed into projections 17 of the ink fountain 1.

Zum Antreiben der Farbwalze 8 ist in einer Stirnseite der Welle 18 eine Aussparung 19 mit quadratischem Querschnitt vorhanden, in die ein Vierkant an einer achsial verschiebbaren und in der nicht dargestellten Seitenwand des Farbkastens 1 gelagerten nicht gezeichneten Antriebswelle eines Motors einführbar ist.To drive the inking roller 8, a recess 19 with a square cross-section is provided in an end face of the shaft 18, into which a square on an axially displaceable and not shown drive shaft of a motor mounted in the side wall of the ink fountain 1, not shown, can be inserted.

Das um eine Welle 20 schwenkbare Rakel 9 kann durch mehrere Justierschrauben 21 zum Einstellen des Farbauftrages verstellt werden.The doctor blade 9, which can be pivoted about a shaft 20, can be adjusted by means of a plurality of adjusting screws 21 for setting the ink application.

Die Farbwalze 8 wird bezogen auf die Fig. 1 im Gegenuhrzeigersinn angetrieben. Nur der untere Teil der Farbwalze 8 taucht ein wenig in die nicht dargestellte Farbe ein. Mit dem Rakel 9 wird die Dicke der von der Farbwalze 8 aufgenommenen Farbschicht reguliert.The inking roller 8 is driven in a counterclockwise direction with reference to FIG. 1. Only the lower part of the inking roller 8 dips a little into the ink, not shown. The thickness of the ink layer picked up by the ink roller 8 is regulated with the doctor blade 9.

Die Heberwalze 6 ist in ihrer Länge in eine Anzahl Abschnitte, z.B. zwanzig, unterteilt. Jeder der Abschnitte 6′ und 6˝, von denen in der Fig. 2 zwei dargestellt sind, ist an einem zweiarmigen Hebel 22 drehbar gelagert. Zu diesem Zweck ist an jedem der Hebel 22 ein abgesetzter Bolzen 23 befestigt. Auf den abgesetzten Teil des Bolzens 23 ist ein Rollenlager 24 aufgesetzt, das eine Buchse 25 trägt. Die Mantelfläche der Buchse 25 ist zur Bildung des Abschnittes 6′ bzw. 6˝ der Hebelwalze mit einer elastischen Schicht 26, vorzugsweise aus Gummi, überzogen.The lifter roller 6 is divided into a number of sections in length, e.g. twenty, divided. Each of the sections 6 'and 6˝, two of which are shown in Fig. 2, is rotatably mounted on a two-armed lever 22. For this purpose, a stepped pin 23 is attached to each of the levers 22. A roller bearing 24, which carries a bushing 25, is placed on the stepped part of the bolt 23. The outer surface of the sleeve 25 is to form the section 6 'or 6' of the lever roller with an elastic layer 26, preferably made of rubber, coated.

Jeder Hebel 22 besitzt etwa in der Mitte eine Aussparung, an deren Randbereich eine Lagerbüchse 27 befestigt ist. Durch alle Lagerbüchsen 27 hindurch erstreckt sich eine gemeinsame Achse 28, um welche die Hebel 22 unabhängig voneinander schwenkbar sind. Die Lagerbüchsen 27 können beispielsweise Gleitbüchsen sein, die ein Futter 29 aus einer Beryllium-Kupfer-Legierung besitzen. Die Lagerbüchsen 27 dienen gleichzeitig als Abstandhalter zwischen benachbarten Hebeln 22.Each lever 22 has a recess approximately in the middle, on the edge region of which a bearing bush 27 is fastened. A common axis 28 extends through all the bearing bushes 27, about which the levers 22 can be pivoted independently of one another. The bearing bushes 27 can, for example, be sliding bushes which have a lining 29 made of a beryllium-copper alloy. The bearing bushes 27 also serve as spacers between adjacent levers 22.

An jedem Hebel 22 ist auf dem dem Heberwalzenabschnitt 6′ bzw. 6˝ gegenüberliegenden Hebelarm je ein Ansatz 30 aus ferromagnetischem Material angeordnet. Der Ansatz 30 dient als Anker für einen Elektromagnet 31. Die Elektromagnete 31 sind mittels je einem abgewinkelten Träger 32 starr mit einer Stützstange 33 mit rechteckigem Querschnitt verbunden. Die Stützstange 33 ist an ihren Enden an der Seitenwand 2 und an der nicht dargestellten Seitenwand des Farbwerkes 1 befestigt.On each lever 22, an approach 30 made of ferromagnetic material is arranged on the lever arm 6 ′ or 6˝ opposite the lever roller section. The approach 30 serves as an anchor for an electromagnet 31. The electromagnets 31 are each rigidly connected to a support rod 33 with a rectangular cross section by means of an angled support 32. The support rod 33 is attached at its ends to the side wall 2 and to the side wall of the inking unit 1, not shown.

Aus der Fig. 1 ist ersichtlich, dass, wenn der Elektromagnet 31 auf eine weiter unten beschriebene Weise erregt wird, dass dann der Ansatz 30 vom Elektromagneten 31 angezogen und der Hebel 22, bezogen auf die Fig. 1 im Uhrzeigersinn, verschwenkt wird. Dies hat zur Folge, dass der dem Hebel 22 zugeordnete Heberwalzenabschnitt 6′ bzw. 6˝ sich von der Reiberwalze 5 abhebt und zum Abheben von Farbe von der Farbwalze 8 auf diese zubewegt wird. Wird der Elektromagnet 31 wieder entregt, so wird der Hebel 22 durch die auf ihn und den zugehörigen Heberwalzenabschnitt 6′ bzw. 6˝ einwirkende Schwerkraft im Gegenuhrzeigersinn verschwenkt, wobei die zuvor von dem Heberwalzenabschnitt 6′ bzw. 6˝ von der Farbwalze 8 abgehobene Farbe auf die Reibwalze 5 übertragen wird.It can be seen from FIG. 1 that when the electromagnet 31 is energized in a manner described below, the extension 30 is then attracted by the electromagnet 31 and the lever 22 is pivoted in a clockwise direction with respect to FIG. 1. This has the consequence that the lever roller section 6 'or 6' assigned to the lever 22 stands out from the friction roller 5 and is moved toward the ink roller 8 to lift ink therefrom. If the electromagnet 31 is de-energized again, the lever 22 is pivoted counterclockwise by the force acting on it and the associated lifting roller section 6 'or 6', the color previously lifted from the lifting roller section 6 'or 6' by the inking roller 8 is transferred to the friction roller 5.

Die durch die Heberwalzenabschnitte 6′ bzw. 6˝ von der Farbwalze 8 auf die Reibwalze 5 übertragene Farbmenge ist von der Drehgeschwindigkeit der Farbwalze 8 bzw. des Heberwalzenabschnittes sowie der Zeit abhängig, während welcher der Elektromagnet 31 erregt ist. Die maximale Dauer, während welcher der Elektromagnet 31 erregt wird, entspricht der Dauer einer Umdrehung des betreffenden Heberwalzenabschnittes 6′ bzw. 6˝. Wird der Elektromagnet 31 während der ganzen genannten Dauer erregt, so nimmt die ganze Manteloberfläche des Heberwalzenabschnittes 6′ bzw. 6˝ Farbe von der Farbwalze 8 auf und es wird die maximale Farbmenge auf die Reiberwalze 5 übertragen.The amount of ink transferred through the lifter roller sections 6 'or 6' from the inking roller 8 to the friction roller 5 is dependent on the speed of rotation of the inking roller 8 or the lifter roller portion and the time during which the electromagnet 31 is energized. The maximum duration during which the electromagnet 31 is excited corresponds to the duration of one revolution of the lifter roller section 6 'or 6' concerned. If the electromagnet 31 is energized for the entire duration mentioned, the entire jacket surface of the lifter roller section 6 'or 6' ink is taken up by the inking roller 8 and the maximum amount of ink is transferred to the friction roller 5.

Wird beispielsweise im Bereich eines der Heberwalzenabschnitte nur die halbe Farbmenge benötigt, so wird der Elektromagnet 31 des betreffenden Heberwalzenabschnittes 6′ bzw. 6˝ nur während der halben der genannten Dauer erregt und demnach nimmt nur die halbe Mantelfläche dieses Heberwalzenabschnittes Farbe von der Farbwalze 8 auf und dementsprechend wird nur die halbe Farbmenge auf die Reiberwalze 5 übertragen. Durch Aendern der Zeit, während welcher der Elektromagnet 31 erregt wird, kann jeder Zwischenwert zwischen Null und Maximum an Farbmenge von der Farbwalze 8 auf die Reiberwalze 5 übertragen werden.For example, if only half the amount of ink is required in the area of one of the lifter roller sections, then the electromagnet 31 of the respective lifter roller section 6 'or 6˝ is only energized for half of the duration mentioned and accordingly only half the lateral surface of this lifter roller section takes up ink from the inking roller 8 and accordingly, only half the amount of paint is on transfer the friction roller 5. By changing the time during which the electromagnet 31 is excited, any intermediate value between zero and maximum amount of ink can be transferred from the inking roller 8 to the friction roller 5.

Solle dieser Maximalwert ausnahmsweise nicht ausreichen, so kann die Rakel 9 der betreffenden Zone mittels der Justierschraube 21 so eingestellt werden, dass die Farbschicht auf der Farbwalze 8 dicker wird.Should this maximum value exceptionally not be sufficient, the doctor blade 9 of the zone in question can be adjusted by means of the adjusting screw 21 so that the ink layer on the ink roller 8 becomes thicker.

Anstelle des zweiarmigen Hebels 22 kann auch ein einarmiger Hebel verwendet werden, wobei dann der Elektromagnet 31 auf der anderen Seite des als Anker dienenden Ansatzes 30 angeordnet werden muss. Ueberdies ist es denkbar, dass anstelle des Elektromagneten 31 ein Elektromotor benützt wird, welcher eine Exzenterscheibe antreibt, die direkt auf den Ansatz 30 einwirkt. Weiter kann eine nicht dargestellte Feder vorgesehen sein, welche den Hebel 22 in seine Ruhestellung, in welcher die Heberwalzenabschnitte 6′ bzw. 6˝ an der Reiberwalze 5 anliegen, bringt, wenn der Elektromagnet 31 nicht erregt ist.Instead of the two-armed lever 22, a one-armed lever can also be used, in which case the electromagnet 31 must then be arranged on the other side of the extension 30 serving as an anchor. In addition, it is conceivable that instead of the electromagnet 31, an electric motor is used which drives an eccentric disk which acts directly on the shoulder 30. Furthermore, a spring, not shown, can be provided, which brings the lever 22 into its rest position, in which the lifter roller sections 6 'and 6' rest on the friction roller 5, when the electromagnet 31 is not energized.

Die Fig. 3 zeigt das Blockschema einer Anlage zum Messen und Einstellen der Farbdichtwerte eines Druckbogens 34, der sich auf einem Messplatz 35 befindet. Nebst dem Messplatz 35 umfasst diese Anlage eine Steuereinrichtung 36, einen Farbdichtemesser 37, der über eine Schnittstelle 38 mit der Steuereinheit 36 verbunden ist, und auf dem Messplatz 35 angeordnete Messabschnittfelder 39, von denen jedes eine Leuchtdiode 40 und eine Drucktaste 41 aufweist.3 shows the block diagram of a system for measuring and setting the color density values of a printed sheet 34 which is located on a measuring station 35. In addition to the measuring station 35, this system includes a control device 36, a color density meter 37, which is connected to the control unit 36 via an interface 38, and measuring section fields 39 arranged on the measuring station 35, each of which has a light-emitting diode 40 and a pushbutton 41.

Durch die Messabschnittfelder 39, beispielsweise zwanzig an der Zahl, wird der Druckbogen in eine Anzahl Abschnitte unterteilt, welche Abschnitte den Heberwalzenabschnitten 6′ bzw. 6˝ entsprechen. Die mit dem Farbdichtemesser 37 an den durch die Messabschnittfelder 39 angegebenen Bereiche des Druckbogens gemessenen Farbdichtemesswerte gelangen über die Schnittstelle 38 in die Steuereinrichtung 36. Damit die Steuereinrichtung 36 erkennen kann, zu welchem Messabschnittfeld 39 der empfangene Farbdichtemesswert gehört, wird dies der Steuereinrichtung 36 durch Betätigen der Drucktaste 41 über Leiter 42 gemeldet. Wenn der empfangene Farbdichtemesswert an der richtigen Stelle gespeichert ist, leuchtet die zugeordnete, über Leiter 43 gesteuerte Leuchtdiode 40 auf und die Farbdichte wird anschliessend im nächstfolgenden Messabschnittfeld 39 durchgeführt. Wie schon erwähnt, werden die ermittelten Farbdichtemesswerte in einem nicht dargestellten Speicher der Steuereinrichtung 36 gespeichert, bis eine neue Messreihe durchgeführt wird. Die Wicklung jedes der zwanzig Elektromagneten 31 ist über einen Leiter eines Leiterbündels 44 mit einem nicht dargestellten Umsetzer in der Steuereinrichtung 36 verbunden. Jeder dieser Umsetzer erzeugt einen Steuerimpuls zum Erregen des zugeordneten Elektromagneten 31, wobei die Dauer des Steuerimpulses vom betreffenden gespeicherten Farbdichtemesswert abhängig ist. Wenn beispielsweise der Farbdichtemesswert vergleichsweise mit einem mittleren Wert klein ist, wird die Dauer des Steuerimpulses verqrössert. Dies hat zur Folge, dass der Elektromagnet 31 länger erregt bleibt, der zugehörige Heberwalzenabschnitt 6′ bzw. 6˝ länger an der Farbwalze 8 anliegt und mehr Farbe aufnimmt, wodurch nach der Entregung des Elektromagneten 31 eine grössere Farbmenge auf die Reiberwalze 5 übertragen wird.The measuring section fields 39, for example twenty in number, divide the printed sheet into a number of sections, which sections form the lifter roller sections 6 'or 6˝ correspond. The color density measurement values measured with the color density meter 37 at the areas of the printed sheet indicated by the measurement section fields 39 reach the control device 36 via the interface 38. So that the control device 36 can recognize to which measurement section field 39 the received color density measurement value belongs, the control device 36 actuates this the push button 41 reported via conductor 42. If the received color density measured value is stored in the correct place, the associated light-emitting diode 40, which is controlled via conductor 43, lights up and the color density is then carried out in the next measuring section field 39. As already mentioned, the determined color density measured values are stored in a memory, not shown, of the control device 36 until a new series of measurements is carried out. The winding of each of the twenty electromagnets 31 is connected via a conductor of a conductor bundle 44 to a converter, not shown, in the control device 36. Each of these converters generates a control pulse for exciting the associated electromagnet 31, the duration of the control pulse being dependent on the stored color density measured value in question. If, for example, the color density measured value is comparatively small with an average value, the duration of the control pulse is increased. The result of this is that the electromagnet 31 remains energized longer, the associated lifter roller section 6 'or 6' bears longer on the inking roller 8 and absorbs more ink, whereby a larger amount of ink is transferred to the friction roller 5 after de-energization of the electromagnet 31.

Beim oben beschriebenen Farbwerk kann der Farbauftrag automatisch in Abhängigkeit der gemessenen Farbdichte reguliert werden und trotzdem ist es im Falle einer Flachandruckpresse möglich, zum Wechseln der Druckfarbe den Farbkasten 15 inklusive der Farbwalze 8 auf einfache Weise und schnell auszutauschen. Hierzu sind keine Aenderungen am Farbkasten notwendig, sondern es können bisher bekannte Farbkasten ohne Aenderung verwendet werden.With the inking unit described above, the ink application can be carried out automatically depending on the measured color density are regulated and nevertheless it is possible in the case of a flat printing press to quickly and easily replace the ink fountain 15 including the inking roller 8 in order to change the printing ink. No changes to the ink fountain are necessary for this, but previously known ink fountains can be used without modification.

Die oben beschriebene, in Abschnitte unterteilte Heberwalze 6 lässt sich ebenso vorteilhalft in einer Auflagedruckmaschine verwenden, in welcher der Farbkasten ein fester Bestandteil der Druckmaschine ist. In diesem Fall wirkt sich dies in einer genaueren Dosierung des Farbaufstriches günstig aus.The above-described lifter roller 6, which is divided into sections, can also advantageously be used in a printing press in which the ink fountain is an integral part of the printing press. In this case, this has a beneficial effect in a more precise dosage of the paint spread.
