Description

Die Erfindung betrifft eine Vorrichtung zum Steuern einer Vielzahl von Stellmotoren an Druckmaschinen, insbesondere zum Einstellen des Farb- oder Feuchtdickenprofils an Offset-Druckmaschinen, die mehrere Druckwerke und eine Vielzahl von einzelnen Zonen jedes Druckwerkes zugeordnete Stellmotoren aufweist, mit einer mit den Stellmotoren gekoppelten Steuereinrichtung zum Ein-und Ausschalten der Stellmotoren und einem die laufenden Stellmotoren speisenden Netzgerät.The invention relates to a device for controlling a plurality of servomotors on printing presses, in particular for setting the color or wet thickness profile on offset printing presses, which has a plurality of printing units and a multiplicity of servomotors assigned to individual zones of each printing unit, with a control device coupled to the servomotors Switching on and off of the servomotors and a power supply unit feeding the running servomotors.

Bei modernen Offset-Druckmaschinen ist das Farblineal durch eine Anzahl nebeneinander angeordneter Stellglieder ersetzt, die in einer bestimmten Zone die Farbdicke bestimmen. Durch unterschiedliche Einstellung dieser Stellglieder läßt sich ebenso ein für das jeweilige Druckmuster optimales Farbdickenprofil einstellen wie mit einem Farbmesser. Die Verstellung der Stellglieder erfolgt in der Weise, daß diese Stellglieder mit einer Einrichtung zur Rückmeldung ihrer Ist-Stellung an die Steuereinrichtung versehen sind, die ihrerseits den Stellmotor solange an das Netzgerät anschließt und dadurch zum Laufen veranlaßt, bis die rückgemeldete Ist-Stellung mit der Soll-Stellung übereinstimmt.In modern offset printing machines, the color ruler is replaced by a number of actuators arranged side by side, which determine the ink thickness in a certain zone. By adjusting these actuators differently, an optimal ink thickness profile for the respective print pattern can be set as with an ink knife. The actuators are adjusted in such a way that these actuators are provided with a device for reporting their actual position to the control device, which in turn connects the servomotor to the power supply unit and thereby causes it to run until the reported actual position with the Target position agrees.

Beim Einrichten der Druckmaschine ist es in der Regel erforderlich, eine Vielzahl der vorhandenen Stellmotoren gleichzeitig einzuschalten. Da die Verstellung in relativ kurzer Zeit erfolgen soll, haben die Stellmotoren eine entsprechend große Leistung und demgemäß auch eine hohe Stromaufnahme. Diese Stromaufnahme ist zudem nicht konstant, sondern hängt beispielsweise von der Farbkonsistenz ab. Auch ist der Strombedarf beim Anlauf des Stellmotors größer als im eingelaufenen Zustand. Ferner können sich Unterschiede von Stellmotor zu Stellmotor durch Unterschiede in der Leichtgängigkeit der notwendigen Getriebe ergeben, die beispielsweise auf Fertigungstoleranzen zurückzuführen sind.When setting up the printing press, it is usually necessary to switch on a large number of the existing servomotors at the same time. Since the adjustment should take place in a relatively short time, the servomotors have a correspondingly high output and accordingly also a high current consumption. This current consumption is also not constant, but depends, for example, on the color consistency. The current requirement when the servomotor starts is greater than when it has run in. Furthermore, differences from servomotor to servomotor can result from differences in the ease of movement of the necessary gears, which can be attributed, for example, to manufacturing tolerances.

Bei bekannten Druckmaschinen ist das Netzgerät so ausgelegt, daß es alle an einem Druckwerk vorgesehenen Stellmotoren gleichzeitig antreiben kann. Da der im ungünstigsten Fall auftretende Strombedarf berücksichtigt werden muß, ist ein solches Netzgerät relativ reichlich dimensioniert. Umfaßt eine Druckmaschine mehrere Druckwerke, wie es für Mehrfarben-Drucke erforderlich ist, so ist auch eine entsprechende Anzahl an Netzgeräten erforderlich. Der dadurch bedingte Aufwand ist relativ groß.In known printing machines, the power supply is designed so that it can drive all the servomotors provided on a printing unit at the same time. Since the worst case power requirement must be taken into account such a power supply is relatively large. If a printing press comprises several printing units, as is required for multi-color printing, a corresponding number of power supply units is also required. The effort involved is relatively large.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Vorrichtung der eingangs genannten Art so auszubilden, daß bei Einhaltung kurzer Einstellzeiten der für die Netzgeräte erforderliche Aufwand bedeutend vermindert werden kann.The invention is therefore based on the object of designing a device of the type mentioned at the outset in such a way that the effort required for the power supply units can be significantly reduced if short response times are observed.

Diese Aufgabe wird nach der Erfindung dadurch gelöst, daß zwischen dem Netzgerät und der Steuerung der Stellmotoren eine von einem Mikroprozessor ansteuerbare, die Anzahl der angesteuerten Stellmotoren begrenzende Strommeßwerterfassung der Ansteuerströme vorgesehen ist.This object is achieved according to the invention in that between the power supply unit and the control of the servomotors, a current measurement of the actuation currents which can be controlled by a microprocessor and limits the number of actuators which are actuated is provided.

Die Erfindung nutzt die Tatsache aus, daß in den seltensten Fällen, ein Bedarf dafür besteht, daß alle Stellmotoren gleichzeitig eingeschaltet werden, und daß außerdem die verschiedenen Stellmotoren eine unterschiedlich lange Laufzeit haben, je nach dem, wie weit das Stellglied beim Einschalten von der Soll-Stellung entfernt ist. Die Steuereinrichtung sorgt dafür, daß das Netzgerät stets mit voller Leistung arbeitet, indem es sofort einen neuen Motor zuschaltet, sobald ein zuvor angeschlossener Motor abgeschaltet wird, weil das zugeordnete Stellglied die gewünschte Soll-Stellung erreicht hat. Daher werden unnötige Wartezeiten vermieden, und es werden alle Stellglieder der Druckmaschine in kürzester Zeit in die Soll-Stellung gebracht. Dabei ist es durchaus möglich, daß gleichzeitig Motoren laufen, die unterschiedlichen Druckwerken zugeordnet sind.The invention takes advantage of the fact that, in the rarest of cases, there is a need for all the servomotors to be switched on at the same time, and also that the various servomotors have different running times, depending on how far the actuator is from the target when it is switched on Position is removed. The control device ensures that the power supply unit always operates at full power by immediately switching on a new motor as soon as a previously connected motor is switched off because the assigned actuator has reached the desired target position. Unnecessary waiting times are therefore avoided and all actuators of the printing press are brought into the desired position in the shortest possible time. It is entirely possible that motors are running at the same time that are assigned to different printing units.

Im einfachsten Fall kann die Steuereinrichtung die Anzahl der eingeschalteten Motoren konstant halten, solange noch Motoren auf das Anschalten warten, weil sich die zugeordneten Stellglieder nicht in der gewünschten Soll-Stellung befinden. Eine Steuerung, die ausschließlich die Anzahl der angeschalteten Motoren konstant hält, berücksichtigt nicht den oben erwähnten, unterschiedlichen Strombedarf der verschiedenen Motoren, so daß noch immmer im Hinblick auf den ungünstigsten Fall das Netzgerät nicht optimal ausgenützt werden kann.In the simplest case, the control device can keep the number of motors switched on as long as motors are still waiting to be switched on because the assigned actuators are not in the desired position. A controller that only keeps the number of connected motors constant does not take into account the different current requirements of the different motors mentioned above, so that the power supply unit cannot always be optimally used in view of the worst case.

Eine in jeder Hinsicht optimale Ausnutzung des Netzgerätes kann in weiterer Ausgestaltung der Erfindung dadurch erzielt werden, daß das Netzgerät derart ausgebildet ist, daß es in Abhängigkeit von der Stärke des allen angeschlossenen Stellmotoren zugeführten Stromes über die Steuereinrichtung mit den Stellmotoren verbunden ist.Optimal utilization of the power supply unit in all respects can be achieved in a further embodiment of the invention in that the power supply unit is such is designed so that it is connected to the servomotors via the control device as a function of the strength of the current supplied to all connected servomotors.

Zu diesem Zweck kann die Steuereinrichtung in besonders einfacher Weise solange das Zuschalten von Motoren zulassen, bis die Gesamt-Stromaufnahme einen unterhalb der Leistungsfähigkeit des Netzgerätes liegenden Grenzwert überschreitet. Dieser Grenzwert muß so gelegt sein, daß auch dann die Leistungsfähigkeit des Netzgerätes nicht überschritten wird, wenn ein Motor bei einer Gesamt-Stromaufnahme zugeschaltet wird, die unmittelbar unterhalb des festgelegten Grenzwertes liegt. Dabei kann jedoch ohne weiteres die augenblickliche Stromüberhöhung unberücksichtigt bleiben, die beim Anlaufen des Motors eintritt, wenn nur die Dauerbelastung innerhalb der Leistungsfähigkeit des Netzgerätes bleibt.For this purpose, the control device can allow the switching on of motors in a particularly simple manner until the total current consumption exceeds a limit value below the performance of the power supply unit. This limit value must be set in such a way that the performance of the power supply unit is not exceeded even if a motor is switched on with a total power consumption that is immediately below the specified limit value. However, the instantaneous current increase that occurs when the motor starts up can be disregarded without further ado, if only the continuous load remains within the performance of the power supply.

Ein besonderer Vorteil der erfindungsgemäßen Steuereinrichtung besteht darin, daß die Motoren unabhängig von ihrer Zugehörigkeit zu einem bestimmten Druckwerk an das Netzgerät angeschlossen werden können, so daß dann, wenn während des Druckes Korrekturen erforderlich sind, ohne weiteres eine Verstellung an allen Druckwerken gleichzeitig erfolgen kann, wenn pro Druckwerk nur wenige Stellmotoren einzuschalten sind. Für den Fall, daß die vorzunehmenden Verstellungen zu groß sind, als daß alle gleichzeitig vorgenommen werden könnten, kann es zweckmäßig sein, einzelnen Motoren oder Motorgruppen Prioritäten zuzuordnen, damit die Steuereinrichtung das Einschalten der Motoren gemäß der Rangfolge ihrer Prioritäten bewirkt.A particular advantage of the control device according to the invention is that the motors can be connected to the power supply regardless of their affiliation to a specific printing unit, so that if corrections are required during printing, an adjustment can readily be made to all printing units simultaneously, if only a few servomotors are to be switched on per printing unit. In the event that the adjustments to be made are too large for all to be able to be carried out at the same time, it may be expedient to assign priorities to individual motors or motor groups so that the control device effects the switching on of the motors according to the order of their priorities.

Die Erfindung wird im folgenden anhand des in der Zeichnung dargestellten Ausführungsbeispieles näher beschrieben und erläutert. Die der Beschreibung und der Zeichnung zu entnehmenden Einzelheiten können bei anderen Ausführungsformen der Erfindung einzeln für sich oder zu mehreren in beliebiger Kombination Anwendung finden. Die Zeichnung zeigt das Schaltbild einer Vorrichtung nach der Erfindung.The invention is described and explained in more detail below with reference to the embodiment shown in the drawing. The details from the description and the drawing can be used in other embodiments of the invention individually or in combination in any combination. The drawing shows the circuit diagram of a device according to the invention.

Die in der Zeichnung schematisch veranschaulichte Vorrichtung umfaßt n-Stellglieder la, lb, ..., ln einer Druckmaschine, die es ermöglichen, die Farbprofile der einzelnen Druckwerke einzustellen, die zu der Druckmaschine gehören. Jedes Stellglied ist einer Zone des Farbdickenprofils zugeordnet. Die Stellglieder Ia, lb, ..., In werden jeweils von Stellmotoren 2a, 2b, ..., 2n angetrieben, die ihrerseits über je einen steuerbaren Schalter 3a, 3b, ... 3n an ein gemeinsames Netzgerät 4 angeschlossen werden können, das bei der dargestellten Ausführungsform zwei selbständige Einheiten 4a, 4b, nämlich eine für den Vorwärtslauf und eine für den Rückwärtslauf der Stellmotoren 2a, 2b, ... 2n, umfaßt, von denen jede als nach der Erfindung gesteuertes NEtzgerät betrachtet werden kann. Der Anschluß der Motoren an das Netzgerät 4 wird unter Mitwirkung einer Strommeßwerterfassung 9 von einem Mikroprozessor 5 gesteuert, dem von den Stellgliedern la, lb, ... In über eine Istwert-Eingabeeinheit 8 Signale über die Ist-Stellungen der einzelnen Stellglieder zugeführt werden. Außerdem werden dem Mikroprozessor von einer geeigneten Sollwert-Eingabeeinheit 6 beispielsweise einem von Drucker zu betätigenden Eingabepult, das auch eine Tastatur 10 umfaßt, für die Soll-Stellungen der Stellglieder la, Ib, ...ln charakteristische Werte zugeführt. Eine Differenz zwischen der von einem Stellglied rückgemeldeten Ist-Stellung zu der Sollwert-Eingabeeinheit 6 geforderten Soll-Stellung zeigt dem Mikroprozessor 5, daß der zugeordnete Stellmotor solange einzuschalten ist, bis die Ist-Stellung mit der Soll-Stellung übereinstimmt. Dabei versteht es sich, daß die Schalter 3a, 3b, ... 3n durch wahlweisen Anschluß an die Einheit 4a oder 4b des Netzgerätes ein selektvies Einschalten von Vor- oder Rücklauf des zugeordneten Motors ermöglichen, je nach dem, ob die Ist-Stellung die Soll-Stellung unter- oder überschreitet.The device schematically illustrated in the drawing comprises n-actuators la, lb, ..., ln in a printing press, which make it possible to set the color profiles of the individual printing units belonging to the printing press ren. Each actuator is assigned to a zone of the color thickness profile. The actuators Ia, lb, ..., In are each driven by actuators 2a, 2b, ..., 2n, which in turn can be connected to a common power supply unit 4 via a controllable switch 3a, 3b, ... 3n, which in the illustrated embodiment comprises two independent units 4a, 4b, namely one for the forward run and one for the reverse run of the servomotors 2a, 2b, ... 2n, each of which can be regarded as a control device controlled according to the invention. The connection of the motors to the power supply unit 4 is controlled by a microprocessor 5 with the aid of a current measurement 9, to which signals from the actuators la, lb,... 8 are fed via an actual value input unit 8 via the actual positions of the individual actuators. In addition, the microprocessor is supplied with characteristic values for the target positions of the actuators la, Ib,... Ln by a suitable target value input unit 6, for example an input desk to be operated by a printer, which also comprises a keyboard 10. A difference between the actual position reported by an actuator to the nominal value input unit 6 shows the microprocessor 5 that the assigned servomotor must be switched on until the actual position matches the nominal position. It goes without saying that the switches 3a, 3b, ... 3n make it possible to selectively switch on the forward or reverse movement of the associated motor, depending on whether the actual position is the, by selectively connecting to the unit 4a or 4b of the power supply Target position falls below or exceeds.

Erfindungsgemäß schaltet der Mikroprozessor nicht alle Stellmotoren 2a, 2b, ... 2n an das Netzgerät 4 an, deren Stellglieder von der Sollage abweichen, sonder jeweils nur so viel, daß die maximale Leisungsfähigkeit des Netzgerätes 4 nicht überschritten wird. Zu diesem Zweck ist in den von den Einheiten 4a und 4b des Netzgerätes 4 zu den Schaltern 3a, 3b, ..., 3n führenden Leitungen je ein Stromwandler 7a bzw. 7b eingeschaltet, von denen jeder einer Strommeßwerterfassung 9 ein Signal zuführt, das für die jeweilige Gesamtstromstärke charakteristisch ist. Der Mikroprozessor 5 steuert mittels einer Schaltersteuerung 11 solange das Zuschalten der Motoren nach der in einem Prioritätsspeicher 12 festgelegten Reihenfolge, bis das Ausgangssignal der Strommeßwerterfassung 9 anzeigt, daß ein vorgegebener Grenzwert überschritten ist. Ist dieser Grenzwert so gewählt, daß er um die maximale Stromaufnahme eines Motors unter der Leistungsfähigkeit des Netzgerätes 4a bzw. 4b liegt, so ist gewährleistet, daß diese Leistungsfähigkeit niemals überschritten wird. Andererseits ist gewährleistet, daß diese Leistungsfähigkeit stets voll ausgenutzt wird, unabhängig davon, wie groß der augenblickliche Strombedarf jedes einzelnen Motors ist. Von besonderem Vorteil ist dabei, daß Stellglieder gleichzeitig verstellt werden können, die verschiedenen Druckwerken zugeordnet sind.According to the invention, the microprocessor does not connect all the servomotors 2a, 2b,... 2n to the power supply unit 4, the actuators of which deviate from the target position, but only so much that the maximum performance of the power supply unit 4 is not exceeded. For this purpose, a current transformer 7a or 7b is switched on in the lines leading from the units 4a and 4b of the power supply 4 to the switches 3a, 3b, ..., 3n, each of which feeds a signal to a current measurement value 9, which for the respective total current is characteristic. The microprocessor 5 controls by means of a switch control 11 the switching on of the motors in the order specified in a priority memory 12 until the output signal of the current measurement value detection 9 indicates that a predetermined limit value has been exceeded. If this limit value is chosen so that it is below the performance of the power supply unit 4a or 4b by the maximum current consumption of a motor, it is ensured that this performance is never exceeded. On the other hand, it is guaranteed that this performance is always fully utilized, regardless of the current current requirement of each individual motor. It is particularly advantageous that actuators that are assigned to different printing units can be adjusted simultaneously.

Dabei wäre es grundsätzlich möglich, daß der Mikroprozessor die Stellglieder zyklisch abfragt und die Motoren in der dadurch gegebenen Reihenfolge nacheinander zuschaltet, bis keine Differenzen zwischen Soll-Stellung und Ist-Stellung mehr bestehen. Dabei würden alle Stellmotoren gleichrangig behandelt. Die Verwendung des Prioritätsspeichers 12 macht es jedoch möglich, die Adressen der Stellglieder in eine solche Ordnung zu bringen, daß stets die Stellung derjenigen Stellglieder zuerst korrigiert wird, deren Korrektur am notwendigsten ist. Beispielsweise können die einem Druckwerk mit einer bestimmten Farbe zugeordneten Stellglieder einen Vorrang vor anderen Stellglieder haben, beispielsweise die der blauen Farbe zugeordneten Stellglieder. Es wäre aber auch denkbar, daß Prioritäten nach der Größe des zu verändernden Weges gesetzt werden, so daß diejenigen Motoren bevorzugt eingeschaltet werden, deren Stellglieder am weitesten von der Soll-Stellung abweichen, um starke Fehleinstellungen zu korrigieren, bevor an anderen Stellungen Feinkorrekturen vorgenommen werden. Derartige Rangfolgen lassen sich mittels des Mikroprozessors 5 und des Prioritätsspeichers 12 ohne weiteres nach bekannten Programmen realisieren.In principle, it would be possible for the microprocessor to poll the actuators cyclically and to switch on the motors one after the other in the order given until there are no longer any differences between the desired position and the actual position. All servomotors would be treated equally. However, the use of the priority memory 12 makes it possible to bring the addresses of the actuators into such an order that the position of those actuators whose correction is most necessary is always corrected first. For example, the actuators assigned to a printing unit with a specific color can take precedence over other actuators, for example the actuators assigned to the blue color. However, it would also be conceivable for priorities to be set according to the size of the path to be changed, so that preference is given to switching on those motors whose actuators deviate the most from the desired position in order to correct severe incorrect settings before fine adjustments are made at other positions . Rankings of this type can easily be implemented by means of the microprocessor 5 and the priority memory 12 according to known programs.

Es versteht sich, daß die Erfindung nicht auf das durch die Zeichnung veranschaulichte Ausführungsbeispiel beschränkt ist, sondern Abweichungen davon möglich sind, ohne den Rahmen der Erfindung zu verlassen. So ist es beispielsweise möglich, das Zuschalten der Motoren nicht von der Gesamt-Stromaufnahme abhängig zu machen, sondern stattdessen die Gesamtzahl der eingeschalteten Motoren zu überwachen und die Anzahl der eingeschalteten Motoren konstant zu halten, solange noch Motoren auf das Einschalten warten. Auch wäre es beispielsweise möglich, den Vergleich zwischen Ist- und Soll-Stellung unmittelbar am Stellglied vorzunehmen und daher vom Stellglied selbst Fehlersignale dem Mikroprozessor zuzuführen.It goes without saying that the invention is not limited to the exemplary embodiment illustrated by the drawing, but deviations are possible without departing from the scope of the invention. For example, it is possible not to make the switching on of the motors dependent on the total current consumption, but instead to monitor the total number of switched on motors and to keep the number of switched on motors constant while the motors are still waiting to be switched on. It would also be possible, for example, to carry out the comparison between the actual and target positions directly on the actuator and therefore to supply error signals to the microprocessor from the actuator itself.

Weiterhin könnte auch die Stromaufnahme der einzelnen Motoren überwacht und an den Mikroprozessor rückgemeldet werden, der daraus die Gesamt-Stromaufnahme berechnet. Weiterhin braucht auch kein Mikroprozessor Verwendung zu finden, sondern es kann stattdessen eine fest verdrahtete Steuereinrichtung verwendet werden. Demgemäß gibt es viele Möglichkeiten, um eine Vorrichtung nach der Erfindung zu realisieren.Furthermore, the current consumption of the individual motors could be monitored and are reported back to the microprocessor, which calculates the total current consumption. Furthermore, there is no need to use a microprocessor, but instead a hard-wired control device can be used. Accordingly, there are many ways to implement a device according to the invention.

Es sei auch darauf hingewiesen, daß die Erfindung nicht auf die Einstellung des Farbdickenprofils bei Offset-Druckmaschinen beschränkt ist, sondern nach der Erfindung Farb- oder auch Feuchtdickenprofile an Druckmaschinen beliebiger Art eingestellt werden können. Außerdem ist es grundsätzlich möglich, weitere Stellmotoren solcher Druckmaschinen in eine solche Vorrichtung einzubeziehen und ggf. mit besonderen Prioritäten zu versehen.It should also be pointed out that the invention is not limited to the setting of the ink thickness profile in offset printing presses, but that color or wet thickness profiles can be set on printing machines of any type according to the invention. In addition, it is fundamentally possible to include further servomotors of such printing presses in such a device and, if necessary, to provide them with special priorities.
