Abstract
Description
Die Erfindung betrifft eine Steuerung für eine Druckmaschine gemäß dem Oberbegriff von Anspruch 1.The invention relates to a control for a printing press according to the preamble of claim 1.
Bogenoffsetdruckmaschinen weisen in der Regel an dem Plattenzylinder eine Einrichtung auf, um den Plattenzylinder gegenüber dem Antriebszahnrad und dem Räderzug zu entkoppeln. Dabei sind Einrichtungen bekannt, bei welchen der Plattenzylinder bis zu einer ganzen Umdrehung gegenüber dem Antriebszahnrad verdreht werden kann. Derartige Einrichtungen werden häufig als Umfangs-Grobregisterverstellung bezeichnet. Weist eine Bogenoffsetdruckmaschinen einen Winkelgeber (Inkrementalgeber, Absolutwinkelgeber) auf, vermittels dem in Verbindung mit dem nachgeschalteten Hauptantrieb der Druckmaschine die Platten- und Gummituchzylinder in bestimmte Positionen verfahren werden können, so ist dies nur möglich, wenn in den einzelnen Druckwerken die Plattenzylinder in der sogenannten Null-Position stehen, also eine vorherige Grob-Umfangsregisterverstellung wieder rückgängig gemacht worden ist. Der Grund hierfür liegt darin, daß in der Steuerung für die einzelnen Druckwerkszylinder Winkelwerte vorgegeben sind, welche dann über den Hauptantrieb angefahren werden, um beispielsweise zum Einlegen einer neuen Druckplatte eine günstige Position der Druckanfang-Klemmschiene des Plattenzylinders zu erzielen. Dies gilt dabei insbesondere für Druckmaschinen, welche halb- oder vollautomatische Druckplattenwechseleinrichtungen aufweisen.Sheet-fed offset printing machines generally have a device on the plate cylinder in order to decouple the plate cylinder from the drive gear and the gear train. Devices are known in which the plate cylinder can be rotated up to a full revolution with respect to the drive gear. Such devices are often referred to as circumferential coarse register adjustment. If a sheet-fed offset printing machine has an angle encoder (incremental encoder, absolute angle encoder), by means of which the plate and blanket cylinders can be moved into certain positions in conjunction with the downstream main drive of the printing press, this is only possible if the plate cylinders in the so-called printing units in the individual printing units Stand zero position, that is, a previous coarse circumference register adjustment has been undone. The reason for this is that in the control system, angle values are specified for the individual printing unit cylinders, which are then approached via the main drive in order, for example, to achieve a favorable position of the printing start clamping rail of the plate cylinder for inserting a new printing plate. This applies in particular to printing presses which have semi or fully automatic printing plate changing devices.
Das gleiche Problem hinsichtlich des Anfahrens bestimmter Platten- oder Gummituchzylinderpositionen ergibt sich dabei bei Bogenoffsetdruckmaschinen mit umstellbaren Bogenwendeeinrichtungen. Die Platten- und Gummituchzylinder in den Druckwerken nach der Wendung sind im Betriebszustand Schön- und Widerdruck entsprechend formatabhängig gegenüber der Grundposition verdreht, so daß über einen Winkelgeber - beispielsweise am ersten Druckwerk - die vorgegebenen Positionen nicht mehr angefahren werden können.The same problem with regard to moving to certain plate or blanket cylinder positions arises in sheet-fed offset printing machines with convertible sheet-turning devices. The plate and blanket cylinders in the printing units after the twist are rotated in the printing and printing mode according to the format, depending on the format, so that the specified positions can no longer be reached via an angle encoder - for example on the first printing unit.
Aus der DE 3 342 662 A1 ist eine Vorrichtung an einer Druckmaschine, bestehend aus einem Platten- und/oder Gummituchzylinder bekannt, bei welcher am Plattenzylinder ein Stellungs-Ist-Geber angebracht ist, vermittels dem in Verbindung mit vorgegebenen Soll-Werten der Plattenzylinder und/oder der Gummituchzylinder in vorgegebene Positionen verfahren werden können. Dieser Stellungs-Ist-Geber kann dabei ein Winkelgeber oder aber auch ein berührungslos Markierungen abtastender Schalter sein. Auf das Problem der Verstellbarkeit von Plattenzylindern wird in dieser Schrift nicht eingegangen, so daß bei einer Druckmaschine mit mehreren Druckwerken entsprechend mehere Winkelgeber anzuordnen sind, was durch den bautechnischen hohen Aufwand als nachteilig anzusehen ist.From DE 3 342 662 A1 a device on a printing press is known, consisting of a plate and / or blanket cylinder, in which an actual position transmitter is attached to the plate cylinder, by means of that in connection with predetermined target values of the plate cylinder and / or the blanket cylinder can be moved into predetermined positions. This actual position encoder can be an angle encoder or a contact-free scanning switch. The problem of the adjustability of plate cylinders is not dealt with in this document, so that in the case of a printing press with a plurality of printing units, correspondingly several angle encoders have to be arranged, which is to be regarded as disadvantageous due to the high construction costs.
Aus der DE 3 940 796 C2 ist es ebenfalls bekannt, einen mit dem Plattenzylinder umlaufenden Winkelgeber für einen automatischen Druckplattenwechsel vorzusehen. Auch in dieser Schrift wird auf das Problem der in Umfangsrichtung verstellbaren Plattenzylinder nicht eingegangen, so daß die voranstehend genannten Nachteile ebenfalls gelten.From DE 3 940 796 C2 it is also known to provide an angle encoder rotating with the plate cylinder for an automatic pressure plate change. In this document, too, the problem of plate cylinders which are adjustable in the circumferential direction is not dealt with, so that the disadvantages mentioned above also apply.
Aus der DE 9 202 899 U1 ist eine Vorrichtung zur Erfassung der Plattenzylinderposition bekannt, welche aus einem gestellfest angebrachten, abstandslos tastenden Sensor besteht, der eine am Plattenzylinder angebrachte Markierung tastet. Wie die Signale, welche bei jeder Umdrehung eines Plattenzylinders entstehen, aber verarbeitet werden, ist in dieser Schrift nicht beschrieben.From DE 9 202 899 U1 a device for detecting the plate cylinder position is known, which consists of a frame-mounted, non-gated sensor which scans a mark made on the plate cylinder. This document does not describe how the signals, which are generated with each revolution of a plate cylinder, but are processed.
Aufgabe der vorliegenden Erfindung ist es daher, eine Steuerung gemäß dem Oberbegriff von Anspruch 1 derartig weiterzubilden, so daß in einfacher Weise gegenüber dem Hauptantrieb verstellbare Zylinder exakt in vorgegebene Positionen verfahren werden können.It is therefore an object of the present invention to develop a control system in accordance with the preamble of claim 1 in such a way that cylinders which are adjustable relative to the main drive can be moved precisely into predetermined positions.
Gelöst wird diese Aufgabe durch die kennzeichnenden Merkmale von Anspruch 1. Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen.This object is achieved by the characterizing features of claim 1. Further developments of the invention result from the subclaims.
Gemäß der Erfindung ist vorgesehen, daß die mit dem Antrieb der Druckmaschine sowie einem eintourig umlaufenden Winkelgeber in Verbindung stehende Steuerung zusätzlich noch die Signale von Sensoren empfängt, welche Markierungen an den Plattenzylindern abtasten. In der Steuerung sind dabei verschiedene Winkelwerte abgespeichert, welche dazu dienen, beispielsweise die Plattenzylinder in den einzelnen Druckwerken in vorgesehene Positionen zu verfahren. In der Steuerung sind ferner Winkelwerte abgespeichert, welche den Werten des Winkelgebers bei Signalabgabe der einzelnen Sensoren entsprechen, befinden sich die Plattenzylinder sich in ihrer Null-Postion. Sind nun ein oder mehrere Plattenzylinder in Umfangsrichtung gegenüber der jeweiligen Null-Position verdreht, so ist durch die Steuerung feststellbar, daß der gespeicherte Winkelwert für einen Plattenzylinder mit der bei Erfassen der Markierung durch den Sensor festgestellten Winkelstellung nicht übereinstimmt. Diese Differenz wird nun durch die Steuerung in die entsprechenden Soll-Winkelwerte zum Positionieren des Plattenzylinders in vorgegebene Positionen eingerechnet. Das Anfahren dieser Positionen erfolgt dabei wieder über die von dem Winkelgeber erfaßten Ist-Stellungswerte der Druckmaschine in Verbindung mit den derartig modifizierten Soll-Werten.According to the invention, it is provided that the control unit which is connected to the drive of the printing press and a rotary encoder rotating in one revolution also receives the signals from sensors which scan markings on the plate cylinders. Various angle values are stored in the control, which serve, for example, to move the plate cylinders in the individual printing units into intended positions. Angle values are also stored in the control, which correspond to the values of the angle transmitter when the individual sensors emit signals, the plate cylinders are in their zero position. If one or more plate cylinders are now rotated in the circumferential direction with respect to the respective zero position, the controller can determine that the stored angle value for a plate cylinder does not match the angular position determined by the sensor when the marking is detected. This difference is now included in the corresponding target angle values for positioning the plate cylinder in predetermined positions by the control. These positions are again approached via the actual position values of the printing machine detected by the angle encoder in connection with the target values modified in this way.
Des weiteren erfolgt die Erläuterung eines Ausführungsbeispiels der Erfindung anhand der Zeichnung. Die Figur zeigt dabei die ersten fünf Druckwerke einer Bogenoffsetdruckmaschine in Reihenbauweise. An einer Anlagetrommel A ist ein Winkelgeber WG angebracht, der gemäß dem Ausführungsbeispiel als ein Absolutwertgeber ausgebildet ist. Die Stellungssignale dieses Winkelgebers WG wrden einer Steuerung S zugeleitet. Die Steuerung S steht mit dem Hauptantrieb HA der Druckmaschine in Verbindung und gibt an diesen entspprechende Kommandos, um vorgegebene Soll-Positionen anzufahren. Dazu sind in der Steuerung S eine Vielzahl von (ersten) Soll-Winkelwerten abgespeichert, welche bestimmten Positionen der Plattenzylinder P in den einzelnen Druckwerken entsprechen. Dabei kann vorgesehen sein, daß für einen Plattenzylinder mehrere Soll-Winkelwerte vorliegen, also um diesen Plattenzylinder beispielsweise in eine Position zum Einführen einer Druckplatte in die Druckanfangsklemmschiene, zum Einführen der Druckplattenhinterkante in die Druckende-Spannschiene usw. zu positionieren. Ferner sind in der Steuerung S auch Soll-Winkelwerte für die einzelnen Plattenzylinder in den Druckwerken abgespeichert, welche dem zylinderbezogenen Aktivieren bestimmter Stellglieder dienen. Hier sei beispielsweise das An- und Abstellen von Feucht- und/oder Farbauftragswalzen genannt.Furthermore, an embodiment of the invention is explained with reference to the drawing. The figure shows the first five printing units of a sheet-fed offset printing machine in series. An angle encoder WG is attached to a system drum A and, according to the exemplary embodiment, is designed as an absolute encoder. The position signals of this angle encoder WG are fed to a control S. The control S is connected to the main drive HA of the printing press and gives appropriate commands to it in order to move to predetermined target positions. For this purpose, a large number of (first) target angle values are stored in the control S, which correspond to specific positions of the plate cylinders P in the individual printing units. It can be provided that there are several setpoint angle values for a plate cylinder, i.e. in order to position this plate cylinder, for example, in a position for inserting a printing plate into the printing start clamping rail, for inserting the printing plate trailing edge into the printing end clamping rail, etc. Furthermore, the control S also stores target angle values for the individual plate cylinders in the printing units, which serve to activate certain actuators in relation to the cylinder. For example, the turning on and off of dampening and / or inking rollers is mentioned here.
In den einzelnen Druckwerken sind den Plattenzylindern P gestellfest Sensoren SR zugeordnet, welche an den einzelnen Plattenzylindern P angebrachte Markierungen tasten. Die einzelnen Sensoren SR geben dabei bei jeder Umdrehung der Plattenzylinder P ein Signal ab, wenn die Markierung am jeweiligen Sensor vorbeiläuft.In the individual printing units, the plate cylinders P are assigned to the frame fixed sensors SR, which feel the markings made on the individual plate cylinders P. The Individual sensors SR emit a signal with each revolution of the plate cylinder P when the marking passes the respective sensor.
In der Steuerung S sind ferner (zweite) Winkelstellungswerte für die einzelnen Plattenzylinder P abgespeichert, die denjenigen Winkelwerten entsprechen, wenn die Sensoren SR die Markierungen auf den Plattenzylindern P im jeweils unverstellten Grundzustand erfassen. Die Steuerung S führt nun für jeden Sensor SR ein Vergleich der Ist-Winkelstellung bei Abgabe eines Signals mit dem dazugehörigen abgespeicherten Winkelwert durch. Ist diese Differenz gleich Null, so ist der Plattenzylinder nicht verstellt, befindet sich also in seiner Grundposition. Soll nun dieser Plattenzylinder auf eine vorgegebene Position gefahren werden, z. B. zum Einführen einer Druckplattenvorderkante in die Druckanfang-Klemmschiene, so führt die Steuerung S dies mit den entsprechenden abgespeicherten (ersten) Soll-Winkelwerten in Zusammenhang mit den über den Winkelgeber WG erfaßten Ist-Winkelwerten durch.The control S also stores (second) angular position values for the individual plate cylinders P, which correspond to those angular values when the sensors SR detect the markings on the plate cylinders P in the respectively unadjusted basic state. The controller S now carries out a comparison of the actual angular position for each sensor SR when a signal is emitted with the associated stored angular value. If this difference is zero, the plate cylinder has not been adjusted and is therefore in its basic position. If this plate cylinder is to be moved to a predetermined position, e.g. B. for inserting a printing plate leading edge into the pressure start clamping rail, the controller S does this with the corresponding stored (first) target angle values in connection with the actual angle values detected via the angle encoder WG.
Bei einem verstellten Plattenzylinder P stimmt der bei Signalabgabe des entsprechenden Sensors SR erfaßte Winkelwert nicht mit dem abgespeicherten (zweiten) Winkelwert überein, so daß sich eine Differenz ergibt. Diese Differenz wird nun mit dem zugehörigen Soll-Winkelwert einer von diesem Plattenzylinder anzufahrenden Position verrechnet, also unter Berücksichtigung eines Vorzeichens (Richtung der Grobregisterverstellung) hinzu addiert. Soll dieser verstellte Plattenzylinder P beispielsweise in die Druckanfang-Position verfahren werden, so ist dieser Stellung nun ein neuer Soll-Winkelwert zum Anfahren vorgegeben (ermittelte Winkeldifferenz Plus gespeicherter erster Soll-Winkelwert). In an sich bekannter Weise steuert nun die Steuerung S den Hauptantrieb HA solange an, bis der über den Winkelgeber WG erfaßte Ist-Winkelwert der Maschine gleich dem neu errechneten und Soll-Winkelwert für die entsprechende Position ist.In the case of an adjusted plate cylinder P, the angle value detected when the corresponding sensor SR is emitted does not match the stored (second) angle value, so that there is a difference. This difference is now offset against the associated target angular value of a position to be approached by this plate cylinder, that is, adding a sign (direction of the rough register adjustment). If this adjusted plate cylinder P is to be moved, for example, to the start of printing position, this position is now given a new setpoint angle value for starting up (determined angle difference plus stored first setpoint angle value). In a manner known per se, the control S now actuates the main drive HA until the actual angle value of the machine detected by the angle transmitter WG is equal to the newly calculated and desired angle value for the corresponding position.
Zur Überprüfung des Funktionszustandes der einzelnen Sensoren SR ist ferner vorgesehen, daß während eines Maschinenlaufes - dies kann durch Abfrage eines geeigneten Signals, beispielsweise des Hauptantriebes HA erfolgen - das Vorhandensein von Flankenwechseln geprüft wird. Bei Fehlen eines Flankenwechsels eines Sensors SR kann dann auf eine Störung geschlossen werden, die beispielsweise darin besteht, daß der Sensor SR selbst defekt ist bzw. daß die Aufhängung des Sensors SR verbogen ist.To check the functional state of the individual sensors SR, it is also provided that the presence of edge changes is checked during a machine run - this can be done by querying a suitable signal, for example the main drive HA. In the absence of an edge change of a sensor SR, it can then be concluded that there is a fault, for example, that the sensor SR itself is defective or that the suspension of the sensor SR is bent.
