Abstract

The speed regulation system, for the individual motor that drive a multi-motor printing press, has separate digital synchronisers for each motor. To avoid register errors the outputs of the register regulators are used as correction signals for the digital synchronisers. The digital synchronisers are also supported by analog speed regulation. The digital synchronisers are connected over selections contacts to the two selection lines. The regulation system can also be used for other types of multi-motor machines that handle endless streams of material.

Description

Längswellenlose Druckmaschine Die Erfindung betrifft eine Einrichtung zum Regeln der Einzelantriebe von registerhaltig arbeitenden Druckmaschinenelementen einer Druckmaschine.Longitudinal shaftless printing machine The invention relates to a device for controlling the individual drives of printing press elements that work in register a printing press.

Aus maschinentechnischen Gründen ist es bei Druckmaschinen heute häufig erwünscht, auf eine gemeinsame mechanische Längswelle für den Antrieb der Druckmaschinenelemente, wie z.B. den Druckwerken und den walzapparaten, zu verzichten und elektrische Einzelan-5riebe hierfür vorzusehen. Der Gleichlauf der Elemente kann dann durch elektrische Mittel erzwungen werden und zwar muß für eine exakte Winkelregelung zwischen den einzelnen Antrieben gesorgt werden.For technical reasons it is common in printing machines today desired, on a common mechanical longitudinal shaft for the drive of the printing machine elements, such as the printing units and the rolling machines, to do without electrical individual drives to be provided for this. The synchronization of the elements can then by electrical means must be forced for an exact angle control between the individual Drives are taken care of.

Bei Druckmaschinen mu: außerdem die Registerhaltigkeit der einzeijien Druckbilder gewährleistet sein. Dies wird bei den bekannten Arordnungen dadurch erreicht, daß von einem Registerregler (vergl. z.B. deutsche Patentschrift 1 112 569) aus dem Vergleich von aus der Bahn aufgedruckten Paßmarken mit anderen Bahn- oder Zylindermarken ein Pehlersignal gebildet wird, das dem Registerfehler proportional ist und zur Verstellung einer Steliwalze im Weg der Bahn dient. Die Bahnwalze wird dabei derart mechanisch durch einen Stellmotor verstellt, daß der Registerfehler möglichst zu Null wird.In the case of printing machines, the registration of the items must also be ensured Print images can be guaranteed. This is the case with the known arrangements achieves that a register regulator (see e.g. German patent specification 1 112 569) from the comparison of passport marks printed on the web with other web or cylinder marks, an error signal is generated that is proportional to the register error is and is used to adjust a Steliwalze in the path of the web. The web roller will mechanically adjusted by a servomotor in such a way that the register error as possible to zero.

Die mechanischen Stelleinrichtungen sind Jedoch häufig stbranfällig una auch platzraubend.However, the mechanical actuating devices are often susceptible to failure and also takes up space.

Dfe Aufgabe der vorliegenden Erfindung besteht darin, bei einer längsweltenlosen Druckmaschine für den winkelgetreuen Gleichlauf der Eingelantriebe zu sorgen und dabei gleichzeitig die Register regelung derart einzubeziehen, daß gesonderte Stellvorrichtungen für die Registerregelung entfallen können.The object of the present invention is to provide a lengthwise worldless Printing machine to ensure the correct-angle synchronization of the single drives and at the same time the registers to include regulation in such a way that separate adjusting devices for register control can be dispensed with.

Diese Aufgabe wird bei einer Einrichtung der eingangs genannten Art dadurch gelöst, daß einer digitalen Gleichlaufwinkelregelung der Einzelantriebe Jeweils eine Registerregelung überlagert ist. Durch einen derartigen Eingriff in die digiskalen Winkelregelungen kann der Registerfehler ohne mechanische Verstelleinrichtungen zum Verschwinden gebracht werden.This task is carried out in a facility of the type mentioned at the beginning solved in that a digital synchronization angle control of the individual drives One register control is superimposed in each case. Such an intervention in the digital angle regulation can be made by the register error without mechanical adjustment devices to be made to disappear.

Anhand einer Zeichnung sei die Erfindung näher erläutert.The invention will be explained in more detail with the aid of a drawing.

Es zeigen: Fig. 1 das Schema einer Gleichlaufregelung und Fig. 2 den Aufbau eines Reglerteiles.They show: FIG. 1 the diagram of a synchronization control and FIG. 2 the Structure of a controller part.

Wie aus Fig. 1 ersichtlich, sollen die Motoren 1 bis 5 der Falzapparate 6 und 7 und der Druckwerke 8 bis 10 winkelgetreu synchronisierbar sein. Hierzu ist für Jeden Motor 1 bis 5 ein Regelteil 11 bis 15 vorgesehen, der aus einem. Stromregler, einem diesen überlagerten analogen Drehzahlregler und einem weiteren überlagerten digitalen Winkelregler besteht (Fig. 2).As can be seen from Fig. 1, the motors 1 to 5 of the folders 6 and 7 and the printing units 8 to 10 can be synchronized true to angle. This is For each motor 1 to 5 a control part 11 to 15 is provided, which consists of a. Current regulator, one superimposed analog speed controller and another superimposed digital angle controller consists (Fig. 2).

Aus Jeweils einem den Falzapparßten 6 bzw. 7 zugeordneten einstellbaren Taktgeber 23, 24 kann über Wahlschienen 25, 26 wahlweise jeder der digitalen Winkelregler seinen digitalen Sollwert über Wahlschalter 17 bis 22 erhalten.In each case an adjustable one assigned to the folding devices 6 and 7, respectively Clock generator 23, 24 can selectively each of the digital angle controllers via selector rails 25, 26 receive its digital setpoint via selector switches 17 to 22.

Außerdem ist zwischen den einzelnen Druckwerken 8 bis 10 bzw.In addition, between the individual printing units 8 to 10 or

zwischen Druckwerk und Falzeinrichtung jeweils noch eine Registerregelung vorgesehen, mit der die Registerabweichungen auf der Druckbahn 16 feststellbar sind. Zur Beseitigung des Registerfehlers wird das Ausgangssignal der Registerregler 36 bis 38 als Korrekturgröße für den digitalen Winkelregelkreis benutzt.Another register control between the printing unit and the folder provided with which the register deviations on the printing web 16 can be determined. To eliminate the register error, the output signal of the register regulator 36 up to 38 used as a correction variable for the digital angle control loop.

Wie aus Fig. 2 ersichtlich, besteht der Regelteil, z.B. 13, aus einem Stromregler 29, der ein den Motor 3 speisendes Thyristorstellglied 28 aussteuert. Der Stromregler 29 erhält seinen Istwert von einem Stromwandler 29a im Stromkreis des Motors 3. Der Sollwert für den Stromregler 29 wird von einem analogen Drehzahlregler 30 geliefert, der seinen Istwert aus einer mit dem Motor 3 gekoppelten Tachometermaschine 35 und seinen Sollwert über einen Digital-Analogwandler 32 von einem der Taktgeber 23 bzw.24 über eine der Wahlschienen 25 bzw. 26 erhält. Gleichzeitig erhält der analoge Drehzahlregler 30 über einen Digital-Analogwandler 37 eine Korrekturgröße aus einem Winkelregler 31. Der Winkelregler 31, dessen Ausgangssignal dem Winkelfehler entspricht, erhält seinen Leitwert von einem mit dem Motor 3 geXuppelten digitalen Impulsgeber 34 und seinen Sollwert über einen der Wahlschalter 18 bzw. 21 von einer der Wahlschienen 25 bzw. 26. Der Winkelregler 31 ist ein digitaler Regler und kann z.B. als Vor- und Rückwärtszähler ausgebildet sein.As can be seen from Fig. 2, the control part, for example 13, consists of one Current regulator 29, which controls a thyristor actuator 28 feeding the motor 3. The current regulator 29 receives its actual value from a current transformer 29a in the circuit of the motor 3. The setpoint for the current controller 29 is provided by an analog speed controller 30 is supplied, its actual value from a tachometer machine coupled to the motor 3 35 and its setpoint value via a digital-to-analog converter 32 from one of the clock generators 23 or 24 via one of the selection rails 25 or 26. At the same time, the analog speed controller 30 via a digital-to-analog converter 37 a correction variable from an angle controller 31. The angle controller 31, the output signal of which corresponds to the angle error corresponds to, receives its conductance from a digital coupled with motor 3 Pulse generator 34 and its setpoint via one of the selector switches 18 and 21 of a the selection rails 25 and 26. The angle controller 31 is a digital controller and can e.g. be designed as up and down counters.

Weiterhin wird dem Eingang des Winkelreglers 31 noch eine Korrekturgröße zugeführt, die dem Registerfehler proportienal ist. Hierzu wird das Ausgangssignal des Registerreglers 37 über einen Spannungsfrequenzmsetzer 39 in ein entsprechendes Korrektursignal für den Winkelregler 31 ungesetzt.Furthermore, a correction variable is added to the input of the angle controller 31 which is proportional to the register error. For this purpose, the output signal of the register controller 37 via a voltage frequency converter 39 into a corresponding one Correction signal for angle controller 31 not set.

Wie nicht näher erläutert, ist es auch möglich, anstelle von Gleichstrommotoren 1 bis 5 Synchronmotoren vorzusehen, die aus einer gemeinscamen Spaimung,sschiene gespeist werden und deren Phasenwirkel zueinander durch entsprechende Einflußnahme auf das Quer- bzw. Längsfeld verändert werden kann.As not explained in more detail, it is also possible instead of DC motors 1 to 5 synchronous motors are to be provided, which come from a common split rail are fed and their phase effects to each other by appropriate influence can be changed on the transverse or longitudinal field.
