Abstract

A quantity of ink is dosed in an inking system of a printing machine, which inking system is provided with at least one dosing device that can be used to modify the quantity of ink which is transferred by the inking system. The dosing device can be adjusted by the use of an adjusting element to modify the quantity of ink that is to be transferred. A modification of the quantity of ink is defined by an adjustment of the adjusting element. The dosing device is adjusted in accordance with a pre-determined correlation between the amount of the adjustment of the adjusting device and the current state of the dosing device. The adjustment of the dosing device is carried out in accordance with the correlation in such a way that a relation between the modification of the quantity of ink caused by the adjustment of the dosing device, and the ink quantity transferred by the dosing device remains essentially constant.

Description

Die Erfindung betrifft Verfahren zur Farbmengendosierung im Farbwerk einer Druckmaschine gemäß den Merkmalen des Anspruches 1,The invention relates to a method for color quantity metering in the inking unit of a printing press according to the features of claim 1,

In bekannten Druckmaschinen werden beispielsweise Farbmesser eingesetzt, um die vom Farbwerk in die Druckmaschine übertragene Farbmenge dosierend verändern zu können. Um die Einstellung an diesen Dosiereinrichtungen durch das Bedienpersonal zu ermöglichen, sind Stellelemente, beispielsweise ein Stellrad oder eine Einstelltastatur im Leitstand der Druckmaschine, vorgesehen. Durch Betätigung dieser Stellelemente kann das Bedienpersonal die Dosierung der vom Farbwerk übertragenen Farbmenge verändern. Bei Verwendung eines Farbmessers kann beispielsweise durch Eingabe eines bestimmten Stellwertes die Öffnung zwischen der Vorderkante des Farbmessers und dem Außenumfang eines die Druckfarbe übernehmenden Farbduktors verändert werden.In known printing machines, for example, colorimeters are used in order to be able to change the quantity of ink transferred from the inking unit to the printing press in a metering manner. To enable the adjustment of these dosing by the operator, adjusting elements, such as a thumbwheel or a setting keyboard in the control room of the printing press, are provided. By operating these control elements, the operator can change the dosage of the ink quantity transferred by the inking unit. When using a colorimeter, for example, by entering a specific control value, the opening between the front edge of the colorimeter and the outer circumference of a color ink accepting the ink can be changed.

Nachteilig an den bekannten Dosiereinrichtungen ist es, dass bei Verstellung des Stellelements um ein bestimmtes Maß jeweils eine gleichgroße Änderung der übertragenen Farbmenge bewirkt wird. Bei Verwendung eines Farbmessers als Dosiereinrichtung bedeutet dies, dass die Öffnung zwischen der Vorderkante des Farbmessers und dem Außenumfang des Farbduktors unabhängig von der aktuellen Stellung des Farbmessers immer um das gleiche Maß verändert wird. Ist der Verstellweg des Farbmessers beispielsweise in eine bestimmte Anzahl von Schritten eingeteilt, beispielsweise hundert Teilschritte, so bewirkt eine Verstellung um einen Teilschritt immer eine gleichgroße Änderung der Öffnung an der Vorderkante des Farbmessers.A disadvantage of the known metering devices is that upon adjustment of the actuating element by a certain amount in each case an equally large change in the transferred amount of ink is effected. When using a colorimeter as a metering device, this means that the opening between the front edge of the colorimeter and the outer circumference of the Farbduktors is always changed by the same amount regardless of the current position of the colorimeter. If the adjustment path of the colorimeter is subdivided, for example, into a certain number of steps, for example a hundred sub-steps, an adjustment by one sub-step always causes an equally large change in the opening at the front edge of the colorimeter.

Diese Art der Farbmengendosierung ist nachteilig, da in den Fällen, in denen nur geringe Farbmengen übertragen werden, eine durch Verstellung des Stellelements bewirkteThis type of Farbmengendosierung is disadvantageous because in cases where only small amounts of ink are transmitted, caused by adjustment of the control element

Farbmengenänderung relativ sehr groß ist. Wird dagegen in der aktuellen Einstellung eine große Farbmenge von der Dosiereinrichtung übertragen, bewirkt eine Verstellung des Stellelements um ein entsprechendes Maß nur eine relativ geringe relative Farbmengenänderung im Vergleich zur aktuellen Farbmenge. Mit anderen Worten bedeutet dies, dass im Bereich der geringen Farbmerigenübertragung, in dem eine besonders sensible Verstellung notwendig ist, nur sehr grob dosiert werden kann, wohingegen im Bereich großer Farbmengen eine unnötig feine Farbmengendosierung erfolgt.Color amount change is relatively very large. If, however, a large amount of ink is transferred from the metering device in the current setting, an adjustment of the actuating element by a corresponding amount only causes a relatively small relative change in color quantity in comparison to the current ink quantity. In other words, this means that only very roughly can be metered in the region of low color transmission, in which a particularly sensitive adjustment is necessary, whereas in the range of large amounts of color an unnecessarily fine Farbmengendosierung takes place.

Die DE 100 55 827 A1 , DE 100 32 765 A1 und die DE 37 43 646 A1 offenbaren Vorrichtungen zum Einstellen einer Farbmenge in Farbwerken von Druckmaschinen. Dabei wird die Farbmenge mittels Aktor betätigten Dosiersystemen in Abhängigkeit verschiedener Parameter verändert.The DE 100 55 827 A1 . DE 100 32 765 A1 and the DE 37 43 646 A1 disclose devices for adjusting an amount of ink in inking units of printing machines. In this case, the amount of ink is changed by means of actuator actuated dosing systems depending on various parameters.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zur Farbmengendosierung im Farbwerk einer Druckmaschine mit guter Einstellung der Dosierung zu schaffen.The invention has for its object to provide a method for Farbmengendosierung in the inking unit of a printing machine with good dosage setting.

Die Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruches 1 gelöst.The object is achieved by the features of claim 1.

Die mit der Erfindung erzielbaren Vorteile bestehen insbesondere darin, dass ein bestimmtes Maß an Verstellung des Stellelements nicht zum jeweils gleichen Maß der Verstellung an der Dosiereinrichtung führt. Vielmehr wird vor bzw. nach Vorgabe einer Farbmengenänderung durch Verstellung des Stellelements die aktuelle Einstellung der Dosiereinrichtung festgestellt und anschließend die Verstellung der Dosiereinrichtung in Abhängigkeit von einer vorgegebenen Korrelation zwischen dem Maß der Verstellung des Stellelements und der aktuellen Stellung der Dosiereinrichtung vorgenommen. Die Feststellung der Einstellung der Dosiereinrichtung kann vor oder nach Vorgabe einer Farbmengenänderung durch Verstellung des Stellelements erfolgen.The advantages achieved by the invention are, in particular, that a certain degree of adjustment of the actuating element does not lead to the same degree of adjustment to the metering device. Rather, the current setting of the metering device is determined before or after specification of a change in color amount by adjusting the actuator and then made the adjustment of the metering device in response to a predetermined correlation between the degree of adjustment of the control element and the current position of the metering device. The determination of the setting of the metering device can be done before or after specification of a color change by adjusting the actuator.

Die vorgegebene Korrelation zwischen dem Maß der Verstellung des Stellelements und der aktuellen Stellung der Dosiereinrichtung kann dabei als mathematische Funktion formuliert sein. Im Ergebnis gelingt es durch das Verfahren insbesondere die jeweils aktuelle Stellung der Dosiereinrichtung derart zu berücksichtigen, dass in den Fällen, in denen kleine Farbmengen vom Farbwerk übertragen werden eine Verstellung des Stellelements nur zu sehr feinfühligen Verstellungen der Dosiereinrichtungen führen. Werden dagegen im aktuellen Zustand des Farbwerks bereits sehr große Farbmengen übertragen, kann die Dosierung sehr viel gröber erfolgen, so dass bereits kleinere Verstellungen des Stellelements zu größeren Änderungen in der Dosierung der Farbmenge führen.The predetermined correlation between the degree of adjustment of the control element and the current position of the metering device can be formulated as a mathematical function. As a result, it is possible by the method in particular to take into account in each case the current position of the metering device such that in the cases in which small amounts of ink are transferred from the inking unit, an adjustment of the actuating element only lead to very sensitive adjustments of the metering devices. If, on the other hand, very large quantities of paint are already being transferred in the current state of the inking unit, the metering can be made much coarser, so that even smaller adjustments of the actuating element lead to larger changes in the metering of the ink quantity.

Nach der Erfindung erfolgt die Korrelation zwischen dem Maß der Verstellung des Stellelements und der aktuellen Verstellung der Dosiereinrichtung derart, dass die Relation zwischen der durch die Verstellung der Dosiereinrichtung verursachten Farbmengenänderung relativ zur aktuell von der Dosiereinrichtung übertragenen Farbmenge jeweils im Wesentlichen konstant bleibt bzw. sich um weniger als 2%, insbesondere um weniger als 1% unterscheidet.According to the invention, the correlation between the degree of adjustment of the control element and the current adjustment of the metering device such that the relation between the caused by the adjustment of the metering ink quantity change relative to the currently transmitted from the metering amount of ink in each case remains substantially constant or to less than 2%, in particular less than 1%.

Die Konstanz der relativen Farbmengenänderung sollte vorzugsweise über den gesamten Dosierbereich der Dosiereinrichtung und/oder über den gesamten Stellbereich des Stellelements vorhanden sein.The constancy of the relative change in color quantity should preferably be present over the entire metering range of the metering device and / or over the entire setting range of the actuating element.

Wird als Dosiereinrichtung ein Farbmesser eingesetzt, dass zur Farbdosierung mit einem Farbduktor im Farbwerk zusammenwirkt, so ist es besonders vorteilhaft, wenn die relative Schichtdickenänderung der auf den Farbduktor übertragenen Farbschicht jeweils konstant bleibt. Dies bedeutet mit anderen Worten, dass das Verhältnis der durch die Verstellung der Dosiereinrichtung bewirkten Schichtdickenänderung zur aktuellen Schichtdicke jeweils konstant ist.If a color meter is used as the metering device, which cooperates with a color ductor in the inking unit for color metering, then it is particularly advantageous if the relative layer thickness change of the ink layer transferred to the ink ductor remains constant in each case. In other words, this means that the ratio of the layer thickness change caused by the adjustment of the metering device to the current layer thickness is constant in each case.

Ein Ausführungsbeispiel der Erfindung ist in den Zeichnungen dargestellt und wird im Folgenden näher beschrieben.An embodiment of the invention is illustrated in the drawings and will be described in more detail below.

In Fig. 1 ist ein Farbwerk 01 für eine Druckmaschine zur Dosierung der Druckfarbe 02 im Querschnitt dargestellt. Ein Farbduktor 03 wird rotatorisch angetrieben, so dass dessen Außenumfang am Reservoir der Druckfarbe 02 vorbeistreicht, wodurch sich eine Farbschicht bestimmter Schichtdicke auf dem Farbduktor 03 bildet. Vom Farbduktor 03 wird die Druckfarbe 02 anschließend mittels einer Filmwalze 04 abgenommen und in Richtung der Druckzone der Druckmaschine weitergefördert.In Fig. 1 is an inking unit 01 for a printing press for metering the ink 02 shown in cross section. A Farbduktor 03 is driven in rotation, so that its outer circumference past the reservoir of the ink 02, whereby a color layer of certain layer thickness forms on the ink fountain roller 03. From the ink fountain roller 03, the ink 02 is then removed by means of a film roller 04 and further conveyed in the direction of the print zone of the printing press.

Zur Dosierung der vom Farbwerk 01 übertragenen Farbmenge dient eine Dosiereinrichtung 06, z. B. ein Farbmesser 06. Das Farbmesser 06 ist verstellbar gelagert, so dass die Farbzonenöffnung S1; S3 (siehe Figur 2) zwischen der Vorderkante des Farbmessers 06 und dem Außenumfang des Farbduktors 03 verändert werden kann. Bei großer Farbzonenöffnung S1; S3 wird viel Druckfarbe 02 übertragen, wohingegen bei kleiner Farbzonenöffnung S1; S3 nur eine geringe Farbmenge übertragen wird.For metering the amount of ink transferred from the inking unit 01 is a metering device 06, z. B. a color meter 06. The color meter 06 is adjustably mounted, so that the ink fountain opening S1; S3 (see FIG. 2 ) between the front edge of the ink blade 06 and the outer periphery of the ink fountain roller 03 can be changed. With large color zone opening S1; S3 will transfer much ink 02, whereas at small ink zone opening S1; S3 only a small amount of color is transferred.

Die Ausführungen beziehen sich auf ein Farbmesser. In axialer Richtung des Farbduktors 03 weist die Dosiereinrichtung 06 eine Vielzahl dieser jeweils unabhängig voneinander einstellbaren Farbmessern 06 auf, für die alle die Ausführungen dieser Erfindung gelten.The explanations refer to a colorimeter. In the axial direction of the ink fountain roller 03, the metering device 06 has a plurality of these independently adjustable ink knobs 06, for which all the embodiments of this invention apply.

Zur fernsteuerbaren Einstellung des Farbmessers 06 dient ein Stellelement, insbesondere ein Stellmotor 07, durch dessen Antrieb die Farbzonenöffnung S1; S3 an der Vorderkante des Farbmessers 06 vergrößert bzw. verkleinert werden kann. Im Stellmotor 07 kann eine Sensorik vorhanden sein, mit der die aktuelle Stellung des Farbmessers 06 messbar bzw. ableitbar ist. Alternativ dazu kann in der Steuerung auch jede Änderung der Stellung des Farbmessers 06 ausgehend von einer Grundstellung gespeichert werden, um die aktuelle Stellung des Farbmessers 06 daraus ableiten zu können.For remotely controllable adjustment of the ink knife 06 is an actuating element, in particular a servomotor 07, by its drive the ink fountain opening S1; S3 on the front edge of the color meter 06 can be increased or decreased. In the servomotor 07, a sensor system may be present, with which the current position of the ink meter 06 can be measured or deduced. Alternatively, any change in the position of the ink meter 06 starting from a basic position can also be stored in the control in order to be able to derive the current position of the ink meter 06 from it.

Wird im Leitstand der Druckmaschine eine Verstellung des Stellelements zur Änderung der vom Farbwerk 01 abgegebenen Farbmenge eingestellt, beispielsweise durch Eingabe eines bestimmten Einstellwertes E1; E2; E3; E4 an einer Tastatur im Leitstand der Druckmaschine, so wird die aktuelle Einstellung des Farbmessers 06 durch die Steuerung abgefragt und mit der im Leitstand eingegeben Verstellung des Stellelements in Korrelation gesetzt. Die anschließende Verstellung des Farbmessers 06 erfolgt dann in Abhängigkeit von dieser Korrelation. Die Wirkungsweise dieser Art des Verfahrens soll nachfolgend anhand des Diagramms in Fig. 2 erläutert werden.If in the control station of the printing press an adjustment of the control element for changing the ink delivered by the ink fountain 01 set color, for example by entering a specific set value E1; E2; E3; E4 on a keyboard in the control room of the printing press, the current setting of the color meter 06 is queried by the controller and set in correlation with the adjustment of the control element input in the control room. The subsequent adjustment of the ink meter 06 then takes place as a function of this correlation. The mode of action of this type of method is described below with reference to the diagram in FIG Fig. 2 be explained.

In Fig. 2 ist die relative Änderung der Farbschichtdicke auf dem Farbduktor 03 über die Farbzonenöffnung S1; S3 zwischen der Vorderkante des Farbmessers 06 und dem Außenumfang des Farbduktors 03 eingetragen. Der Funktionsgraph A repräsentiert dabei den Zusammenhang, wie er sich nach einem Einstellverfahren ergibt. Gemäß diesem Einstellverfahren ist nämlich der Stellbereich der Eingabe für den Stellmotor 07 in eine Vielzahl, z. B. in hundert Schritte eingeteilt, denen auf dem Funktionsgraph A jeweils ein bestimmter Punkt zugeordnet ist. Der Abstand zwischen diesen Punkten in Richtung der Achse der Eingabe E1; E2; E3; E4 für die Farbzonenöffnung S1; S3 ist jeweils äquidistant groß. Dabei ist der Eingabewert proportional zum Stellbereich des Stellmotors. Dies bedeutet, dass alle Stellschritte eine gleich große Veränderung der Schichtdicke auf dem Farbduktor 03 bewirken. Dies führt im Ergebnis dazu, dass der Funktionsgraph A bei Antragung der relativen Schlchtdickenänderung über die Farbzonenöffnung S1; S3 einen hyperbolischen Verlauf annimmt.In Fig. 2 is the relative change of the ink layer thickness on the ink fountain roller 03 via the ink fountain opening S1; S3 entered between the front edge of the colorimeter 06 and the outer periphery of the ink fountain roller 03. The function graph A represents the relationship as it results after a setting process. Namely, according to this adjustment method, the setting range of the input for the positioning motor 07 is in a plurality, e.g. B. divided into a hundred steps, each of which is assigned a specific point on the function graph A. The distance between these points in the direction of the axis of input E1; E2; E3; E4 for the ink zone opening S1; S3 is equidistant in size. The input value is proportional to the setting range of the servomotor. This means that all adjusting steps cause an equally large change in the layer thickness on the ink ductor 03. As a result, the function graph A upon application of the relative Schlchtdickenänderung over the ink fountain opening S1; S3 assumes a hyperbolic course.

Weiter ist in Fig. 2 auch der Funktionsgraph B angetragen, der sich bei dem erfindungsgemäßen Verfahren zur Farbmengendosierung ergibt. Der Stellbereich des Stellmotors 07 ist in hundert Schritte eingeteilt, die auf dem Funktionsgraphen B als Punkte angedeutet sind. Der Abstand dieser Punkte auf dem Funktionsgraph B in Richtung der Achse der Farbzonenöffnung S1; S3 ist dabei nicht äquidistant groß, sondern vergrößert sich mit zunehmender Farbzonenöffnung S1; S3. Dies beruht darauf, dass die Korrelation zwischen der jeweiligen Änderung der Farbzonenöffnung ΔS12; ΔS34 immer in Abhängigkeit von der aktuellen Farbzonenöffnung S1; S3 erfolgt, so dass die relative Schichtdickenänderung relative Änderung = Änderung der Farbzonenöffnung / Aktuelle Farbzonenöffnung

Figure imgb0001

konstant bei ungefähr 7% verbleibt.Next is in Fig. 2 also the function graph B presented, which results in the method according to the invention for color quantity metering. The setting range of the servomotor 07 is divided into a hundred steps, which are indicated on the function graph B as points. The distance of these points on the function graph B in the direction of the axis of the ink fountain opening S1; S3 is not equidistantly large, but increases with increasing color zone opening S1; S3. This is because the correlation between the respective change of the ink fountain opening ΔS12; ΔS34 always as a function of the current ink zone opening S1; S3 occurs, so that the relative layer thickness change relative change = Change of the ink zone opening / Current color zone opening
Figure imgb0001

remains constant at about 7%.

Auch hierbei ist die Eingabe für den Stellbereich in äquidistante Schritte eingeteilt. Allerdings bewirkt eine gleich große Änderung der Eingabe bei geringer Farbzonenöffnung ΔE12; ΔE34 auch eine geringere Änderung der Farbzonenöffnung ΔS12; ΔS34 als eine entsprechende Änderung der Eingabe bei groBer Farbzonenöffnungen ΔE34; ΔE34. Im Ergebnis ermöglicht es also das erfindungsgemäße Verfahren im Bereich der geringen Farbschichtdicken sehr feinfühlig zu dosieren, wohingegen bei großen Farbschichtdicken, d. h. bei weiter Farbzonenöffnung S1; S3, eine relativ grobe Farbdosierung erfolgt.Again, the input for the control range is divided into equidistant steps. However, an equal change in the input causes a small ink zone opening ΔE12; ΔE34 also a smaller change of the ink fountain opening ΔS12; ΔS34 as a corresponding change in the input at large color zone openings ΔE34; ΔE34. As a result, it makes it possible to meter the method according to the invention very sensitively in the area of low ink layer thicknesses, whereas with large ink layer thicknesses, ie. H. at wide ink zone opening S1; S3, a relatively coarse color metering takes place.

In der Fig. 2 sind auf der oberen Achse die Werte für die Eingabe E1, E2, E3, E4 zur Verstellung des Stellelementes in z. B. äquidistanten, vorzugsweise diskreten Schritten aufgetragen. Bei einer ersten Stellung bei niedriger Farbzonenöffnung S1 beträgt die Anzeige E1 und wird z. B. in der Anzeige auf E2, also um ΔE21, verändert, was eine Veränderung der Farbzonenöffnung von S1 auf S2, also um ΔS21 bewirkt: E 2 - E 1 = ΔE 21 ; S 2 - S 1 = ΔS 21

Figure imgb0002
In the Fig. 2 are on the upper axis, the values for the input E1, E2, E3, E4 for adjusting the actuator in z. B. equidistant, preferably discrete steps applied. In a first position at low ink zone opening S1, the display is E1 and z. B. in the display on E2, ie by ΔE21, changed, causing a change in the ink fountain area of S1 to S2, ie by ΔS21: e 2 - e 1 = AE 21 ; S 2 - S 1 = .DELTA.S 21
Figure imgb0002

Bei einer zweiten Stellung bei hoher Farbzonenöffnung S3 beträgt die Anzeige E3 und wird z. B. in der Anzeige auf E4, also um ΔE43, verändert, was eine Veränderung der Farbzonenöffnung von S3 auf S4, also um ΔS43 bewirkt. E 4 - E 3 = ΔE 43 ; S 4 - S 3 = ΔS 43

Figure imgb0003
In a second position at high color zone opening S3, the display is E3 and z. B. in the display on E4, ie by ΔE43, which causes a change in the ink fountain area of S3 to S4, ie by ΔS43. e 4 - e 3 = AE 43 ; S 4 - S 3 = .DELTA.S 43
Figure imgb0003

Dabei ist ΔE21 = ΔE43 vorzugsweise gleich oder unterscheiden sich um höchstens 10%, insbesondere um höchstens 5%.In this case, ΔE21 = ΔE43 is preferably the same or different by at most 10%, in particular by at most 5%.

Dagegen unterscheiden sich die dadurch erfolgten Farbzonenöffnungen S1 ; S3 um ΔS21 und ΔS43, vorzugsweise um mindestens 5% oder mindestens um 10%.On the other hand, the color zone openings S1 which have occurred thereby differ; S3 by ΔS21 and ΔS43, preferably by at least 5% or at least by 10%.
