Die Erfindung bezieht sich auf ein Kontrollsystem zur Kontrolle einer Anzahl von Farbkästen mit Farbzonenschrauben in einer Druckmaschine. Die Erfindung kann in Druckmaschinen unterschiedlicher Konstruktion angewandt werden. Die nachfolgende Beschreibung repräsentiert die vorliegende Erfindung nur im Zusammenhang mit einer lithographischen Mehrfarben-Druckmaschine.The invention relates to a control system for checking a number of ink fountains with ink fountain keys in a printing press. The invention can be applied to printing presses of various designs. The following description represents the present invention only in connection with a multi-color lithographic printing machine.

Nach Fig. 1 hat eine lithographische
Mehrfarben-Druckmaschine 10 eine Anzahl von Druckwerken 20, 30, 40 und 50. Obwohl vier Druckwerke gezeigt sind, versteht es sich von selbst, daß die Anzahl der betriebenen Druckwerke verschieden sein kann. Die Druckwerke 20, 30, 40, 50 haben jeweils ein Paar Farbkästen, wie es aus dem Stand der Technik bekannt ist.1 has a lithographic
Multi-color printing machine 10 a number of printing units 20, 30, 40 and 50. Although four printing units are shown, it goes without saying that the number of printing units operated can be different. The printing units 20, 30, 40, 50 each have a pair of ink fountains, as is known from the prior art.

Jedes Druckwerk umfaßt einen oberen und unteren Plattenzylinder (nicht gezeigt) und einen jeweils mit diesen zusammenwirkenden oberen und unteren Gummituchzylinder (nicht gezeigt). Jedes Druckwerk druckt auf eine diesem zugeordnete Seite einer durch die Maschine 10 transportierten Materialbahn. Jedem oberen und unteren Plattenzylinder ist ein Farbkasten für den Farbauftrag zugeordnet. Wie vom Stand der Technik wohlbekannt, wird Farbe aus einem Farbkasten auf den zugeordneten Plattenzylinder übertragen, während sich letzterer dreht. Das Druckbild auf der Platte wird auf den Gummituchzylinder übertragen, von wo es wiederum auf die zugeordnete Seite der durch dieses Druckwerk bewegten Materialbahn übertragen wird.Each printing unit includes an upper and lower plate cylinder (not shown) and one with each interacting upper and lower blanket cylinders (not shown). Each printing unit prints on a side of a material web transported by the machine 10 assigned to it. A color box for the color application is assigned to each upper and lower plate cylinder. As is well known in the art, ink is transferred from an ink fountain to the associated plate cylinder as the latter rotates. The print image on the plate is transferred to the blanket cylinder, from where it is in turn transferred to the assigned side of the material web moved by this printing unit.

Im einzelnen hat das Druckwerk 20 einen oberen Farbkasten 25 und einen unteren Farbkasten 26. Das Druckwerk 30 hat einen oberen Farbkasten 35 und einen unteren Farbkasten 36. Das Druckwerk 40 hat einen oberen Farbkasten 45 und einen unteren Farbkasten 46. Das Druckwerk 50 hat einen oberen Farbkasten 55 und einen unteren Farbkasten 56.In particular, the printing unit 20 has an upper ink fountain 25 and a lower ink fountain 26. The printing unit 30 has an upper ink fountain 35 and a lower ink fountain 36. The printing unit 40 has an upper ink fountain 45 and a lower ink fountain 46. The printing unit 50 has an upper fountain Ink fountain 55 and a lower ink fountain 56.

Jeder der Farbkästen 25, 26, 35, 36, 45, 46, 55 und 56 hat die gleiche Konstruktion und Funktion. Der Einfachheit halber ist die Konstruktion und Funktion nur des in Fig. 2 dargestellten Farbkastens 25 im Detail beschrieben. Der Farbkasten 25 hat eine Farbkastenwalze 21, welche sich seitlich quer über das Druckwerk 20 erstreckt. Ein gegliedertes Farbmesser 22 befindet sich neben der Farbkastenwalze 21 und erstreckt sich seitlich quer über die Farbkastenwalze 21.Each of the ink fountains 25, 26, 35, 36, 45, 46, 55 and 56 has the same construction and function. For the sake of simplicity, the construction and function of only the ink fountain 25 shown in FIG. 2 is described in detail. The ink fountain 25 has an ink fountain roller 21 which extends laterally across the printing unit 20. A structured ink knife 22 is located next to the ink fountain roller 21 and extends laterally across the ink fountain roller 21.

Ein Spalt 23 für den Farbfilm wird zwischen der äußeren Umfangsfläche 23 der Farbkastenwalze 21 und der unteren Kante 27 des Farbmessers 22 gebildet. Dieser Spalt 23 ist hier zur Veranschaulichung in übertriebener Dimension dargestellt. Der Spalt 23 ist an vielen Stellen in seitlicher Richtung entlang der Farbkastenwalze 21 verstellbar, was eine stellenbezogene Steurung der aus dem Farbkasten 25 auf die zugehörigen Druckzylinder (nicht gezeigt) in dem Druckwerk 20 zugeführten Farbe erlaubt.A gap 23 for the ink film is formed between the outer peripheral surface 23 of the ink fountain roller 21 and the lower edge 27 of the ink knife 22. This gap 23 is shown here for illustration in an exaggerated dimension. The gap 23 is adjustable in many places in the lateral direction along the ink fountain roller 21, which is a position-related control of the ink fountain 25 on the associated printing cylinder (not shown) allowed in the ink supplied to the printing unit 20.

Das Farbmesser 22 und die Farbkastenwalze 21 formen ein Farbreservoir 28 auf eine Weise, die im Stand der Drucktechnik wohlbekannt ist. Es wird Farbe aus dem Farbreservoir durch den zwischen der Umfangsfläche 24 der Farbkastenwalze 21 und der unteren Kante 27 des Farbmessers gebildeten Spalt zugeführt, um dadurch eine kontrollierte Dicke des Farbfilms auf der Farbkastenwalze herzustellen.The ink knife 22 and ink fountain roller 21 form a color reservoir 28 in a manner well known in the printing art. Ink is supplied from the ink reservoir through the gap formed between the peripheral surface 24 of the ink fountain roller 21 and the lower edge 27 of the ink knife, to thereby produce a controlled thickness of the ink film on the ink fountain roller.

Es sind eine Anzahl von Verstellvorrichtungen 60 zur Dosierung des Farbflusses seitlich an dem Farbkasten 25 wirksam angebracht. Jede der Verstellvorrichtungen 60 preßt gegen eine zugeordnete Stelle an dem Farbmesser 22 und steuert oder reguliert auf diese Weise die Breite des Spalts 23 zwischen der Farbkastenwalze 21 und dem Farbmesser 22 an solchen zugeordneten Stellen an dem Farbmesser 22.A number of adjustment devices 60 for dosing the ink flow are effectively attached to the side of the ink fountain 25. Each of the adjustment devices 60 presses against an assigned point on the ink knife 22 and in this way controls or regulates the width of the gap 23 between the ink fountain roller 21 and the ink knife 22 at such assigned points on the ink knife 22.

Jede der Verstelleinrichtungen 60 hat eine Farbzonenschraube 61, welche durch Schraubbewegung einen festen Teil des Rahmens des Farbkastens 25 kontaktiert. Die Farbzonenschraube hat einen spitzen Teil, welcher gegen den zugeordneten Teil des Farbmessers 22 drückt. An der Stelle der Farbzonenschraube ist die Breite des Spalts 23 zwischen dem Farbmesser 22 und der Farbkastenwalze 21 regulierbar, indem die Farbzonenschraube in oder aus dem Rahmen des Farbkastens geschraubt wird. Die Farbzonenschraube 61 wird von einem in zwei Richtungen wirkenden Stellmotor 62 getrieben. Der Motor 62 bewegt die Farbzonenschraube 61 axial ein und aus.Each of the adjustment devices 60 has an ink zone screw 61, which contacts a fixed part of the frame of the ink fountain 25 by screwing. The ink fountain key has a pointed part which presses against the assigned part of the ink knife 22. At the location of the ink fountain key, the width of the gap 23 between the ink knife 22 and the ink fountain roller 21 can be regulated by screwing the ink fountain head screw into or out of the frame of the ink fountain. The ink zone screw 61 is driven by a servomotor 62 which acts in two directions. The motor 62 axially moves the ink fountain key 61 in and out.

Ein Potentiometer 63 ist wirksam mit einer diesem zugeordneten Farbzonenschraube 61 verbunden. Die Impedanz des Potentiometers steht im funktionellen Zusammenhang mit der Position der Farbzonenschraube 61. Somit dient das Potentiometer 63 dazu, die Position der Farbzonenschraube 61 zu ermitteln und die Breite des Spalts 23 in dem der Farbzonenschraube zugeordneten Bereich an dem Farbmesser zu überwachen.A potentiometer 63 is operatively connected to an ink zone screw 61 assigned to it. The impedance of the potentiometer is functionally related to the Position of the ink fountain key 61. The potentiometer 63 thus serves to determine the position of the ink fountain key 61 and to monitor the width of the gap 23 in the area assigned to the ink fountain key on the ink knife.

Jedes Druckwerk hat eine diesem zugeordnete Farbkasten-Kontrolleinrichtung. Im einzelnen hat das Druckwerk 20 (Fig. 1) eine Farbkasten-Kontrolleinrichtung 70. Das Druckwerk 30 hat eine Farbkasten-Kontrolleinrichtung 74. Das Druckwerk 40 hat eine Farbkasten-Kontrolleinrichtung 78. Das Druckwerk 50 hat eine Farbkasten-Kontrolleinrichtung 82.Each printing unit has an ink fountain control device assigned to it.

The control panel 100 further includes one by the operator Touch-activated display field 104 (operator touch-screen display) and a sheet inspection area 106 as support for a printed sheet, which has an image printed by one or a combination of the printing units 20, 30, 40, 50. The control panel 100 also includes a series of manually operated remote selection switches 108 for controlling the positions of the ink fountain keys in a selected ink fountain. The row of switches 108 is divided into pairs. Each pair of switches is associated with a respective ink zone screw and a predetermined zone of the sheet inspection surface 106, which corresponds to a lateral position on the ink knife in each of the printing units.

Die Bedienkonsole 100 umfaßt außerdem ein Graphik-Anzeigepaneel 110 (bar graph display panel) als Hilfe für den Bediener beim Verstellen der Farbzonenschrauben in ihre gewünschten Positionen. Das Anzeigepaneel 110 hat eine Anzahl Zonen mit Reihen von Leuchtdioden ("LED"). Die Anzahl der Zonen mit LED-Reihen entspricht der Anzahl der Farbzonenschrauben und der Anzahl der Schalterpaare 108. Vorzugsweise ist die einem jeden der Farbkästen zugeordnete Anzahl der Farbzonenschrauben sechsunddreißig, die Anzahl der Schalterpaare 108 sechsunddreißig und die Anzahl der Zonen mit LED-Reihen in dem Anzeigepaneel 110 sechsunddreißig.The control panel 100 also includes a bar graph display panel 110 to assist the operator in adjusting the ink fountain keys to their desired positions. The display panel 110 has a number of zones with rows of light emitting diodes ("LEDs"). The number of zones with LED rows corresponds to the number of ink zone screws and the number of switch pairs 108. Preferably, the number of ink zone screws assigned to each of the ink fountains is thirty-six, the number of switch pairs 108 thirty-six and the number of zones with LED rows in that Display panel 110 thirty six.

Das Anzeigefeld 104 sieht eine Bediener-Inputeinrichtung für den Kontrollbetrieb der Druckwerke 20, 30, 40, 50 einschließlich des Wählens eines Farbkastens und des Wählens der in diesem Farbkasten zu verstellenden Farbzonenschrauben vor. Das Anzeigefeld 104, die Schalter 108 und das Anzeigepaneel 110 sind elektrisch mit der zentralen Steuervorrichtung 102 verbunden. Auf dem Anzeigefeld 104 können dem Bediener Informationen von der zentralen Steuervorrichtung 102 angezeigt werden, und für den Bediener ist es leicht, Informationen an die zentrale Steuervorrichtung 102 durch einfaches Berühren des Anzeigefelds 104 in den entsprechenden, durch ein System-Softwareprogramm ermittelten Stellen einzugeben. Solche Berührungs-Anzeigefelder sind im Stand der Technik wohlbekannt und werden hier nicht im Detail beschrieben.The display field 104 provides an operator input device for the control operation of the printing units 20, 30, 40, 50 including the selection of a color box and the selection of the ink fountain keys to be adjusted in this color box. The display panel 104, the switches 108 and the display panel 110 are electrically connected to the central control device 102. Information from the central control device 102 can be displayed to the operator on the display panel 104, and it is easy for the operator to send information to the central control device 102 simply by touching the Enter display field 104 in the corresponding positions determined by a system software program. Such touch panels are well known in the art and are not described in detail here.

Die zentrale Steuervorrichtung 102 ist vorzugsweise ein Computer des Typs Modell 286 PC AT. Die zentrale Steuervorrichtung 102 wirkt mit dem Anzeigefeld 104 zusammen und erzeugt eine Reihe von Menüs und/oder graphische Darstellungen, welche den einzelnen Druckwerken 20, 30, 40, 50 zugeordnet werden. Eine Bediener-Überwachungstafel mit einer Reihe von Wahlschaltern befindet sich neben dem Anzeigefeld 104 und ist ein weiteres Input-Mittel für den Bediener zur Kontrolle der individuellen Druckwerke.The central control device 102 is preferably a Model 286 PC AT computer. The central control device 102 interacts with the display field 104 and generates a series of menus and / or graphic representations which are assigned to the individual printing units 20, 30, 40, 50. An operator monitoring panel with a series of selector switches is located next to the display field 104 and is another input means for the operator to control the individual printing units.

Die zentrale Steuervorrichtung 102 hat eine zugehörige Datenkontrolleinrichtung 116. Wenn der Bediener einen Befehl in die zentrale Steuervorrichtung 102 eingibt, dann werden die Daten parallel verarbeitet. Die Datenkontrolleinrichtung 116 stellt eine Hochgeschwindigkeits-Serienverbindung zu den Druckwerken her, indem sie die parallelen Daten von der zentralen Steuervorrichtung 102 in Seriendaten umwandelt. Auch fügt die Datenkontrolleinrichtung 116 ein Schwachstromsignal für den Datenaustausch mit den Farbkasten-Kontrolleinrichtungen hinzu.The central control device 102 has an associated data control device 116. When the operator enters a command into the central control device 102, the data are processed in parallel. The data control device 116 establishes a high-speed serial connection to the printing units by converting the parallel data from the central control device 102 into serial data. The data controller 116 also adds a low power signal for data exchange with the ink fountain controllers.

Jede Farbkasten-Kontrolleinrichtung hat eine zugeordnete Farbkasten-Datenkontrolleinrichtung. Im einzelnen ist die Farbkasten-Kontrolleinrichtung 70 operativ mit der Farbkasten-Datenkontrolleinrichtung 120 verbunden. Die Farbkasten-Kontrolleinrichtung 74 ist operativ mit der Farbkasten-Datenkontrolleinrichtung 122 verbunden. Die Farbkasten-Kontrolleinrichtung 78 ist operativ mit der Farbkasten-Datenkontrolleinrichtung 124 verbunden. Die Farbkasten-Kontrolleinrichtung 82 ist operativ mit der Farbkasten-Datenkontrolleinrichtung 126 verbunden.Each ink fountain controller has an associated ink fountain data controller. In particular, the ink fountain control device 70 is operatively connected to the ink fountain data control device 120. The ink fountain controller 74 is operatively connected to the ink fountain data controller 122. The ink fountain control device 78 is operatively connected to the ink fountain data control device 124. The Ink fountain controller 82 is operatively connected to ink fountain data controller 126.

Die Datenkontrolleinrichtung 116 ist durch ein einziges Paar verdrillter Drähte 140 mit jeder der Farbkasten-Datenkontrolleinrichtungen 120, 122, 124 und 126 verbunden. Dieses Paar verdrillter Drähte 140 bildet eine Serienleitung. Jeder von der zentralen Steuervorrichtung 102 ausgesandte Befehl beinhaltet einen Code, welcher einen Bestimmungskontrollknotenpunkt oder eine Bestimmungsaddresse darstellt. Jede der Farbkasten-Kontrolleinrichtungen hat eine zugeordnete, spezifische Knotenpunktaddresse. Die Farbkasten-Datenkontrolleinrichtung erhält einen Befehl über die Serienleitung und verarbeitet das Schwachstromsignal und gibt die Kontrollinformation in der Form eines Leistungssignal an die Farbkasten-Kontrolleinrichtung weiter. Wenn die Addresse in dieser Meldung mit der Adresse für diese Farbkasten-Kontrolleinrichtung übereinstimmt, dann führt diese Farbkasten-Kontrolleinrichtung den Befehl zum motorischen Positionieren an dem entsprechenden Farbkasten aus und sendet eine Meldung zurück zu der zentralen Steuervorrichtung 102, wenn die motorischen Bewegungen der Farbzonenschrauben vollzogen sind.The data controller 116 is connected to each of the ink fountain data controllers 120, 122, 124 and 126 by a single pair of twisted wires 140. This pair of twisted wires 140 form a series line. Each command sent from the central controller 102 includes a code that represents a destination control node or address. Each of the ink fountain controllers has an associated, specific node address. The ink fountain data controller receives a command via the serial line and processes the low current signal and passes the control information to the ink fountain controller in the form of a power signal. If the address in this message matches the address for this ink fountain controller, then this ink fountain monitor executes the motor positioning command on the corresponding ink fountain and sends a message back to the central controller 102 when the ink fountain screw motions are completed are.

Jede der Farbkasten-Kontrolleinrichtungen hat einen zugeordneten, operativ mit dieser verbundenen Speicher. Im einzelnen ist die Farbkasten-Kontrolleinrichtung 70 mit einem Speicher 150 verbunden. Die Farbkasten-Kontrolleinrichtung 74 ist mit einem Speicher 152 verbunden. Die Farbkasten-Kontrolleinrichtung 78 ist mit einem Speicher 156 verbunden. Die Farbkasten-Kontrolleinrichtung 82 ist mit einem Speicher 158 verbunden. In jedem dieser zugeordneten Farbkastenspeicher ist das Programm für den Betrieb der zugeordneten Farbkasten-Kontrolleinrichtung gespeichert. Die Farbkasten-Kontrolleinrichtungen sind vorzugsweise kommerziell erhältliche Mikrocomputer des Typs, die einen Analog-zu-Digital-Umwandler, eine Parallelschaltung, einen Serienkanal und Input/Outputkanäle zum An- und Abschalten der Farbzonenschrauben-Antriebsmotoren haben.Each of the ink fountain control devices has an associated memory operatively connected to it. In detail, the ink fountain control device 70 is connected to a memory 150. The ink fountain control device 74 is connected to a memory 152. The ink fountain control device 78 is connected to a memory 156. The ink fountain control device 82 is connected to a memory 158. The program for operating the assigned ink fountain control device is stored in each of these assigned ink fountain memories. The ink fountain controllers are preferably commercially available microcomputers of the type that have an analog-to-digital converter, a parallel connection, a series channel and input / output channels for switching the ink fountain key drive motors on and off.

Die Farbkasten-Kontrolleinrichtungen üben die Kontrolle über die Position der diesen jeweils zugeordneten Farbzonenschrauben in den jeweiligen Druckwerken grundsätzlich in einem geschlossenen Regelkreis aus. Wenn eine Farbkasten-Kontrolleinrichtung einen Positionierbefehl erhält, so wird durch diese der Motor angetrieben und damit die zugeordnete Farbzonenschraube in die befohlene Position gebracht. Die Farbkasten-Kontrolleinrichtung überwacht das Feedback-Potentiometer, um zu gewährleisten, daß die tatsächliche Position der Farbzonenschrauben der gewünschten Position entspricht. Ist dies der Fall, so stoppt die Farbkasten-Kontrolleinrichtung die Farbzonenschrauben-Antriebsmotoren.The ink fountain control devices basically exercise control over the position of the ink zone screws assigned to them in the respective printing units in a closed control loop. When an ink fountain control device receives a positioning command, the motor is driven by it and thus the assigned ink fountain key is brought into the commanded position. The ink fountain controller monitors the feedback potentiometer to ensure that the actual position of the ink fountain keys corresponds to the desired position. If this is the case, the ink fountain control device stops the ink fountain key drive motors.

Jede der Farbkasten-Kontrolleinrichtungen kann nachfolgende Befehle in ihrem zugeordneten Speicher speichern, auch wenn sie einen gegenwärtigen Bewegungsbefehl noch nicht zu Ende geführt hat. Der neu erhaltene Befehl bleibt einfach in dem zugeordneten Speicher bis sich die Farbkasten-Kontrolleinrichtung diese Information für das Steuern der Farbzonenschrauben in den jeweiligen Druckwerken herausholt.Each of the ink fountain controllers can store subsequent commands in their associated memory even if it has not yet completed a current move command. The newly received command simply remains in the assigned memory until the ink fountain control device gets this information for controlling the ink fountain keys in the respective printing units.

Es ist offensichtlich, daß die Anordnung der vier Farbkasten-Kontrolleinrichtungen und der zentralen Steuervorrichtung ein verteiltes Kontrollsystem für die Kontrolle des Betriebs der Druckmaschine 10 darstellt. Solch ein verteiltes Kontrollsystem, wie in Fig. 1 gezeigt, liefert eine Reihe vorteilhafter Resultate. Von Vorteil ist es, daß die Farbzonenschrauben eines Farbkastens eines Druckwerks gleichzeitig mit den Farbzonenschrauben eines Farbkastens eines anderen Druckwerks bewegt werden können. Dieser Vorteil beruht auf der Tatsache, daß die zentrale Steuervorrichtung einen Farbzonenschrauben-Positionierbefehl an eine zweite Farbkasten-Kontrolleinrichtung senden kann, während die Verstellung der Farbzonenschrauben eines anderen Farbkastens aufgrund eines vorher gegebenen Befehls an die diesem zugeordnete Kontrolleinrichtung noch im Gange ist. Mit "gleichzeitig" ist gemeint, daß die Farbzonenschrauben eines Farbkastens verstellt werden, während die Farbzonenschrauben eines anderen Farbkastens verstellt werden, jedoch nicht notwendigerweise phasengleich. Immer wenn die zentrale Steuervorrichtung einen Befehl gibt, übernimmt die zuständige Farbkasten-Kontrolleinrichtung die Steuerung der eigentlichen Farbzonenschraubenbewegung, so daß die zentrale Steuervorrichtung frei ist, einen weiteren Befehl zu geben. Tatsächlich hängt die Geschwindigkeit, mit welcher das vorliegende System arbeiten kann, einzig und allein von der Geschwindigkeit ab, mit welcher ein Bediener Positionierbefehle eingibt. Es ist für den Bediener nicht notwendig zu warten, bis der eine Positionierbefehl erfüllt ist, bevor er einen weiteren Positionierbefehl eingibt.It is evident that the arrangement of the four ink fountain control devices and the central control device constitutes a distributed control system for controlling the operation of the printing machine 10. Such a distributed control system, as shown in Figure 1, provides a number of beneficial results. It is advantageous that the ink zone screws of a color box of a printing unit can be moved simultaneously with the ink zone screws of a color box of another printing unit. This advantage is based on the fact that the central control device can send an ink fountain key positioning command to a second ink fountain control device, while the adjustment of the ink fountain head screws of another ink fountain is still in progress due to a previously given command to the control device assigned to it. By "simultaneously" it is meant that the ink fountain keys of one ink fountain are adjusted while the ink fountain bolts of another ink fountain are adjusted, but not necessarily in phase. Whenever the central control device gives a command, the responsible ink fountain control device takes over control of the actual ink fountain key movement, so that the central control device is free to give another command. In fact, the speed at which the present system can operate depends solely on the speed at which an operator issues positioning commands. It is not necessary for the operator to wait until one positioning command has been fulfilled before entering another positioning command.
