Abstract

The machine has three units (3,4,7) connected together by a forced drive (22) and driven by separate electric motors (18,19,21). One motor (18) with its control loop (24) and rotational speed set-point (26) acts as a master, and the other two with their control loops (36,37) dependent upon the master current set-point (28) as slaves. Each slave control loop incorporates a smoothing filter (46) for the set-point current with a parameter-setting input (47) and a current output level adaptor (39). This provides a desired value which is compared (41) with the actual current (44) drawn by the slave motor concerned.

Description

Die Erfindung betrifft eine Drehzahlregeleinrichtung für einen Mehrmotorenantrieb von Baueinheiten einer Druckmaschine gemäß dem Oberbegriff des Anspruches 1.The invention relates to a speed control device for a multi-motor drive of structural units of a printing press according to the preamble of claim 1.

Aus der DE 41 32 765 A1 ist eine Drehzahlregeleinrichtung für einen Mehrmotorenantrieb einer Druckmaschine bekannt. Bei dieser Drehzahlregeleinrichtung ist ein Führungsantriebsmotor mit vorgeordneter Regelstrecke angeordnet und jeder weitere Antriebsmotor weist eine eigene, von der Regelstrecke des Führungsantriebsmotors gesteuerte Regelstrecke auf.From DE 41 32 765 A1 a speed control device for a multi-motor drive of a printing press is known. In this speed control device, a guide drive motor with an upstream control path is arranged and each further drive motor has its own control path controlled by the control path of the guide drive motor.

Die DE 42 14 394 A1 beschreibt eine Rotationsdruckmaschine mit Einzelantrieben. Die Einzelantriebe der Druckstellengruppen beziehen ihre Referenzposition vom Falzapparat.DE 42 14 394 A1 describes a rotary printing press with individual drives. The individual drives of the printing point groups get their reference position from the folder.

Die "Siemens-Zeitschrift" 51 (1977) Heft 5, Seiten 387 bis 398 beschreibt einen Mehrmotorenantrieb für Rotationsdruckmaschinen. Im Zusammenhang mit einem Registerregler wird gemäß Bild 4 ein Filter verwendet. Die Reglerstruktur beruht nicht auf einem Komplex von zusammengeschalteten Antrieben.The "Siemens-Zeitschrift" 51 (1977) Issue 5, pages 387 to 398 describes a multi-motor drive for rotary printing presses. A filter is used in connection with a register controller as shown in Figure 4. The controller structure is not based on a complex of interconnected drives.

Der Erfindung liegt die Aufgabe zugrunde, eine Drehzahlregeleinrichtung für einen Mehrmotorenantrieb von Baueinheiten einer Druckmaschine zu schaffen, mit der Antriebsmotoren für Baueinheiten mit sich unterscheidenden Momentenverlauf geregelt werden können.The invention has for its object to provide a speed control device for a multi-motor drive units of a printing press, with the drive motors for units with different torque curve can be controlled.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des kennzeichnenden Teiles des Anspruches 1 gelöst.This object is achieved by the features of the characterizing part of claim 1.

In vorteilhafter Weise wird durch die erfindungsgemäße Drehzahlregeleinrichtung für einen Mehrmotorenantrieb einer Druckmaschine erreicht, daß eine Baueinheit, insbesondere ein Falzapparat, mit stark schwankenden Momentenbedarf von einem Antriebsmotor angetrieben wird, dessen Regelung auf diesen schwankenden Momentenbedarf schnell reagiert und somit eine gleichmäßige Drehzahl erreicht wird. Dieser Antriebsmotor wird als Leitantrieb herangezogen. Gleichzeitig werden Baueinheiten, insbesondere Druckeinheiten, mit weniger schwankenden Momentenbedarf von Antriebsmotoren angetrieben, deren Regelstrecke von diesem schwankenden, aber geglätteten Momentenbedarf abhängig ist. Damit werden diese Baueinheiten nicht zu Schwingungen infolge der Regelung des Leitantriebes angeregt.
Vorteilhaft ist, daß die Folgeantriebe mit einem Proportionalitätsfaktor bewertet werden können, so daß bestimmte Folgemotoren innerhalb des Mehrmotorenantriebes zu eindeutigen Momentensenken oder Momentenlieferanten definiert werden. Damit ist eine klare Momentenflußrichtung innerhalb der Druckmaschine auch bei sich veränderten Lastverhalten festgelegt. Somit werden Druck- oder Schwingungsprobleme, beispielsweise Passerversatz, infolge z. B. Zahnflankenwechsels oder Spiels in einer Antriebswelle verhindert.Advantageously, the speed control device according to the invention for a multi-motor drive of a printing press ensures that a structural unit, in particular a folder with a strongly fluctuating torque requirement is driven by a drive motor, the control of which reacts quickly to this fluctuating torque requirement and thus a uniform speed is achieved. This drive motor is used as a master drive. At the same time, structural units, in particular pressure units, are driven by drive motors with less fluctuating torque requirements, the controlled system of which is dependent on this fluctuating but smoothed torque requirement. This means that these components are not excited to vibrate as a result of the control of the master drive.
It is advantageous that the slave drives can be evaluated with a proportionality factor, so that certain slave motors within the multi-motor drive are defined as unique torque sinks or torque suppliers. This defines a clear direction of torque flow within the printing press even when the load behavior changes. Thus, pressure or vibration problems, such as register misalignment, due to z. B. tooth flank change or play in a drive shaft prevented.

Eine erfindungsgemäße Drehzahlregeleinrichtung ist in der Zeichnung schematisch dargestellt und wird im folgenden näher beschrieben.A speed control device according to the invention is shown schematically in the drawing and is described in more detail below.

Eine Druckmaschine, z. B. eine Bahn 1 verarbeitende Rollenrotationsdruckmaschine besteht beispielsweise aus einer Rollenlagerung 2, einer aus zwei Brückendruckwerken 3, 4 gebildeten H-Druckeinheit 6 und einem Falzapparat 7. In den Brückendruckwerken 3, 4 sind jeweils zwei Form- und Gummizylinder 8, 9, 11, 12 bzw. 13, 14, 16, 17 über einen Zwangsantrieb, d. h. formschlüssigen Antrieb, z. B. einen Zahnradzug, miteinander verbunden. Der Falzapparat 7 und die beiden Brückendruckwerke 3, 4 werden jeweils von einem eigenen Elektromotor 18, 19, 21 angetrieben und sind mittels eines Zwangsantriebes, z. B. einer Antriebswelle 22, formschlüssig synchronisiert verbunden. Die Elektromotoren 18, 19, 21 können als Gleich- oder Drehstrommotoren ausgeführt sein. Im Ausführungsbeispiel werden Gleichstrommotoren beschrieben. Bei Verwendung von Drehstromantrieben werden die den Momenten entsprechenden Größen zur Regelung verwendet. Diese Rollenrotationsdruckmaschine kann selbstverständlich auch aus einer Vielzahl von Druckeinheiten, auch anderer Art, z. B. in Reihenbauweise, und mehreren Falzapparaten zusammengesetzt sein.
Der Antriebsmotor 18 der Baueinheiten mit den größten Momentenschwankungen, im vorliegenden Beispiel der Antriebsmotor 18 des Falzapparates 7, ist als mit einem Drehzahlgeber 23 versehener Leitantriebsmotor ("Master") 18 vorgesehen. Dazu ist dem Leitantriebsmotor 18 eine Regelstrecke 24 vorgeordnet. Diese Regelstrecke 24 besteht aus einem Drehzahlsollwertgeber 26, einem Drehzahlsummationspunkt 27, einem Drehzahlregler 28, einem Stromsummationspunkt 29, einem Stromregler 31, einem Leistungsteil 32 und einem Stromistwertgeber 33. Der Drehzahlsollwertgeber 26 ist mit dem ersten Eingang des Drehzahlsummationspunktes 27 und der Drehzahlgeber 23 ist mit dem zweiten Eingang verbunden. Der Ausgang des Drehzahlsummationspunktes 27 ist über den Drehzahlregler 28 auf einen ersten Eingang des Stromsummationspunktes 29 geführt. Der zweite Eingang des Stromsummationspunktes 29 ist mit dem in einer Stromzuführleitung 34 angeordneten Stromistwertgeber 33 des Leitantriebmotores 18 verbunden. Der Ausgang des Stromsummationspunktes 29 ist über den Stromregler 31 und dem nachgeschalteten Leistungsteil 32 mit dem Leitantriebsmotor 18 verbunden.
Den beiden als nebengeordneten Folgeantriebsmotoren 19, 21 ("Slaves") vorgesehenen Antriebsmotoren 19, 21 der Brückendruckwerke 3, 4 und anderen möglichen zusätzlich angeordneten Antriebsmotoren ist jeweils eine weitere Regelstrecke 36, 37 vorgeschaltet. Diese Regelstrecke 36, 37 besteht jeweils aus einem Stromsollwertgeber 38, einer Strompegelanpassung 39, einem Stromsummationspunkt 41, einem Stromregler 42, einem Leistungsteil 43 und einem Stromistwertgeber 44. Der dem Drehzahlregler 28 nachgeordnete Stromsollwertgeber 38 ist mit einem Filter 46 zur Glättung des Stromsoliwertes. Diesem Stromsollwertgeber 38 ist die Strompegelanpassung 39 nachgeschaltet, die auf einen ersten Eingang des Stromsummationspunktes 41 führt. Über eine Eingabestation 47 lassen sich der Filter 46 und die Strompegelanpassung 39 parametrieren. Der zweite Eingang des Stromsummationspunktes 41 ist wiederum mit dem in einer Stromzuführleitung 48 angeordneten Stromistwertgeber 44 des jeweiligen Folgeantriebsmotores 19, 21 verbunden. Der Ausgang dieses Stromsummationspunktes 41 ist über den Stromregler 42 und dem nachgeschalteten Leistungsteil 43 mit dem jeweiligen Folgeantriebsmotor 19, 21 verbunden.A printing machine, e.g. B. a web 1 processing Web-fed rotary printing press consists, for example, of a roller bearing 2, an H-printing unit 6 formed from two bridge printing units 3, 4 and a folder 7. In the bridge printing units 3, 4 there are two forme and rubber cylinders 8, 9, 11, 12 and 13, 14, respectively , 16, 17 via a positive drive, ie positive drive, for. B. a gear train connected to each other. The folder 7 and the two bridge printing units 3, 4 are each driven by their own electric motor 18, 19, 21 and are by means of a positive drive, for. B. a drive shaft 22, positively synchronized connected. The electric motors 18, 19, 21 can be designed as DC or three-phase motors. In the exemplary embodiment, DC motors are described. When using three-phase drives, the quantities corresponding to the torques are used for control. This web-fed rotary printing press can of course also be made from a large number of printing units, including other types, e.g. B. in series, and several folders.
The drive motor 18 of the structural units with the greatest fluctuations in torque, in the present example the drive motor 18 of the folder 7, is provided as a master drive motor (“master”) 18 provided with a speed sensor 23. For this purpose, a control system 24 is arranged upstream of the master drive motor 18. This controlled system 24 consists of a speed setpoint generator 26, a speed summation point 27, a speed controller 28, a current summation point 29, a current controller 31, a power unit 32 and a current actual value transmitter 33. The speed setpoint transmitter 26 is connected to the first input of the speed summation point 27 and the speed transmitter 23 is connected to the second input. The output of the speed summation point 27 is routed via the speed controller 28 to a first input of the current summation point 29. The second input of the current summation point 29 is connected to the current actual value transmitter 33 of the master drive motor 18 arranged in a current supply line 34. The output of the current summation point 29 is connected to the master drive motor 18 via the current regulator 31 and the downstream power section 32.
A further control system 36, 37 is connected upstream of the two drive motors 19, 21 of the bridge printing units 3, 4, which are provided as secondary drive motors 19, 21 (“slaves”), and other possible additionally arranged drive motors. These controlled systems 36, 37 each consist of a current setpoint generator 38, a current level adjustment 39, a current summation point 41, a current regulator 42, a power unit 43 and a current actual value generator 44. The current setpoint generator 38 downstream of the speed regulator 28 is provided with a filter 46 for smoothing the current solitary value. This current setpoint generator 38 is followed by the current level adjustment 39, which leads to a first input of the current summation point 41. Via an input station 47, the filter 46 and the Parameterize current level adjustment 39. The second input of the current summation point 41 is in turn connected to the current actual value transmitter 44 of the respective slave drive motor 19, 21 arranged in a power supply line 48. The output of this current summation point 41 is connected to the respective slave drive motor 19, 21 via the current controller 42 and the downstream power section 43.

Die Funktionsweise der erfindungsgemäßen Drehzahlregeteinrichtung für einen Mehrmotorenantrieb ist folgendermaßen:
Mittels des Drehzahlsollwertgebers 26 wird ein Drehzahlsollwert nSOLL auf den Drehzahlsummationspunkt 27 gegeben. Dort wird der Drehzahlsollwert nSOLL mit dem vom Drehzahlgeber 23 erfaßten Drehzahlistwert nIST verglichen und eine etwaig bestehende Differenz dem Drehzahlregler 28 zugeführt. Der Drehzahlregler 28 bestimmt an seinem Ausgang einen Stromsollwert ISOLL, der einerseits dem Stromsummationspunkt 29 des Leitantriebsmotors 18 und andererseits dem Stromsollwertgeber 38 der Regelstrecke 36, 37 jedes Folgeantriebsmotores 19, 21 zugeführt wird. Im Stromsummationspunkt 29 wird der Stromsollwert ISOLL mit dem vom Stromistwertgeber 33 erfaßten Stromistwert IIST des Leitantriebmotores 18 verglichen und eine bestehende Differenz dem Stromregler 31 zugeführt. Der Stromregler 31 steuert mittels des Leistungsteiles 32 den Leitantriebsmotor 18 an.The mode of operation of the speed control device according to the invention for a multi-motor drive is as follows:
A speed setpoint n SET is given to the speed summation point 27 by means of the speed setpoint generator 26. There, the speed setpoint n TARGET is compared with the actual speed value n ACTUAL detected by the speed sensor 23 and any difference that may exist is fed to the speed controller 28. The speed controller 28 determines at its output a current setpoint I SOLL , which is supplied on the one hand to the current summation point 29 of the master drive motor 18 and on the other hand to the current setpoint generator 38 of the controlled system 36, 37 of each slave drive motor 19, 21. At the current summation point 29, the current setpoint I SOLL is compared with the current actual value I IST of the master drive motor 18 detected by the current actual value transmitter 33 and an existing difference is fed to the current controller 31. The current controller 31 controls the master drive motor 18 by means of the power section 32.

Die Regelstrecke 36, 37 des jeweiligen Folgeantriebsmotores 19, 21 erhält vom Ausgang des Drehzahlreglers 28 den Stromsollwert ISOLL, der dem Stromsollwertgeber 38 zugeführt wird. Im Stromsollwertgeber 38 wird dieser Stromsollwert ISOLL des Leitantriebsmotores 18 geglättet und mittels der Pegelanpassung 39 ein Stromsollwert für den Folgeantriebsmotor 19, 21 einem ersten Eingang des Stromsummationspunktes 41 zugeführt. Dort wird ein vom Stromistwertgeber 44 erfaßter Stromistwert des Folgeantriebsmotores 19, 21 mit dem Stromsollwert verglichen. Eine etwaig bestehende Differenz wird dem Stromregler 42 zugeführt, der mittels des Leistungsteiles 43 den Folgeantriebsmotor 19, 21 ansteuert.The controlled system 36, 37 of the respective slave drive motor 19, 21 receives the current setpoint I SET , which is supplied to the current setpoint generator 38, from the output of the speed controller 28. In the current setpoint generator 38, this current setpoint I SOLL of the master drive motor 18 is smoothed and a current setpoint for the slave drive motor 19, 21 is fed to a first input of the current summation point 41 by means of the level adjustment 39. There, an actual current value of the slave drive motor 19, 21 detected by the current actual value transmitter 44 is compared with the current setpoint. Any existing difference is fed to the current controller 42, which controls the follower motor 19, 21 by means of the power section 43.

Es ist auch möglich, nicht jeder Baueinheit 3; 4; 7 einen eigenen Elektromotor 18; 19; 21 zuzuordnen, sondern allen untereinander in formschlüssiger Antriebsverbindung stehenden Baueinheiten 3; 4; 7 nur zwei Elektromotoren 18; 19; 21 zuzuordnen. Jeder formschlüssige Antriebszug wird somit von mindestens zwei Elektromotoren 18; 19; 21 - einem Master 18 und mindestens einem Slave 19; 21 - angetrieben.It is also possible not every unit 3; 4; 7 its own electric motor 18; 19; 21 to be assigned, but rather all of the structural units 3; 4; 7 only two electric motors 18; 19; 21 assign. Each positive drive train is thus by at least two electric motors 18; 19; 21 - a master 18 and at least one slave 19; 21 - driven.

Auch ist es möglich, innerhalb einer Baueinheit 3; 4; 7 zwei Elektromotoren 18; 19; 21 anzuordnen.
Gemeinsam ist allen Ausführungen, daß für einen formschlüssigen Antrieb 22 (auch innerhalb einer Druckeinheit) zwei Motoren vorgesehen sind. Dieser Antrieb 22 kann auch aus Zahnrädern bestehen, die Zylinder 8, 9; 11, 12 bzw. 13, 14, 16, 17 eines Brückendruckwerkes 3, 4 miteinander formschlüssig verbinden.It is also possible within a structural unit 3; 4; 7 two electric motors 18; 19; 21 to arrange.
All versions have in common that two motors are provided for a positive drive 22 (also within a printing unit). This Drive 22 can also consist of gears, the cylinders 8, 9; 11, 12 or 13, 14, 16, 17 of a bridge printing unit 3, 4 connect positively to one another.

Der Filter 46 zur Glättung des Stromsollwertes ist vorzugsweise als Tiefpaß (z. B. RC-Glied oder LC-Schaltung) ausgeführt.The filter 46 for smoothing the current setpoint is preferably designed as a low-pass filter (for example an RC element or LC circuit).

Dieser Filter 46 kann als aktiver (z. B. Operationsverstärker und LC- oder RC-Beschaltung) oder passiver (z. B. RC-Glied, LC-Glied) Tiefpaß oder auch als digitaler Filter ausgebildet sein.This filter 46 can be designed as an active (eg operational amplifier and LC or RC circuit) or passive (eg RC element, LC element) low-pass filter or as a digital filter.
