Description
Die Erfindung betrifft eine Einrichtung zur Registerkontrolle gemäß dem Oberbegriff von Anspruch 1.The invention relates to a device for register control according to the preamble of claim 1.
Bei Druckmaschinen und insbesondere Bogenoffsetdruckmaschinen werden die Druckformen bzw. Druckplatten mit je einer dem Druckanfang und dem Druckende zugeordneten Klemmeinrichtung auf dem Form- bzw. Plattenzylinder gehalten. Für die Qualität des Mehrfarbendruckes ist dabei der registergerechte Übereinanderdruck der Einzelfarben durch die einzelnen Druckformen von entscheidender Bedeutung. Demzufolge sind die einzelnen Druckformen lagegenau auf dem Form- bzw. Plattenzylinder anzubringen. Dazu sind zahlreiche Registersysteme entwickelt worden, welche beispielsweise aus in der Druckanfang-Klemmeinrichtung angeordneten Stiften bzw. Anschlägen bestehen, die mit an der entsprechenden Kante der Druckform bzw. Druckplatte angebrachten Ausstanzungen zusammenwirken.In printing machines and in particular sheetfed offset printing machines the printing plates or printing plates with one each Start of print and end of print associated with the print end held on the form or plate cylinder. For the quality multi-color printing is the register-based overprinting of the individual colors through the individual printing forms vital. As a result, the individual Printing forms lie exactly on the form or plate cylinder to install. Numerous register systems have been developed for this which, for example, in the pressure start clamping device arranged pins or stops exist, with the corresponding edge of the printing form or Punch the cut-outs on the pressure plate.
Bekannt sind Einrichtungen zur Registerkontrolle, bei denen die Registerstifte bzw. Registeranschläge elektrisch abfragbar ausgebildet sind. Dies kann in einfacher Weise dadurch geschehen, daß die Registerstifte bzw. die Anschläge elektrisch isoliert gegenüber der Klemmschiene bzw. dem Zylinder angeordnet sind, so daß durch die registergerechte Anlage der Druckform bzw. Druckplatte ein elektrischer Stromkreis geschlossen wird. Die registergerechte Anlage ist beispielsweise durch am Zylinder bzw. den Registeranschlägen angebrachte Leuchtmittel (Leuchtdioden) anzeigbar. Eine derartige Ausgestaltung eignet sich besonders für die visuelle Kontrolle für von Hand auf dem Zylinder aufzubringende Druckformen.Facilities for register control are known in which the register pins or register stops can be queried electrically are trained. This can be done easily happen that the register pins or the stops electrically insulated from the clamping rail or the cylinder are arranged so that by the registered system of the Printing form or printing plate, an electrical circuit closed becomes. The register-compliant system is, for example by attached to the cylinder or the register stops Illuminants (LEDs) can be displayed. Such a configuration is particularly suitable for visual control for printing forms to be applied by hand to the cylinder.
Bei halb- bzw. vollautomatischen Druckplattenwechslern ist das Signal der Registerabfrage durch eine Steuerung auszuwerten, um nach dem Zuführen einer neuen Druckplatte und Feststellen der registergerechten Anlage die entsprechende Klemmschiene zum Befestigen der Platte zu schließen. Die das Signal auswertende, das Schließen der Schiene bewirkende sowie die weiteren Vorgänge des Wechselvorganges auslösende Steuerung ist außerhalb des Platten- bzw. Druckformzylinders angeordnet, so daß das Signal der elektrisch abfragbaren Registerstifte aus dem drehbar gelagerten Zylinder herausgeleitet werden muß.With semi or fully automatic printing plate changers evaluate the signal of the register query by a controller, order after feeding a new printing plate and finding the corresponding clamping rail of the system in accordance with the register to fasten the plate. The the Signal evaluating, causing the rail to close as well as triggering the other processes of the change process Control is outside the plate or printing form cylinder arranged so that the signal of the electrically interrogable Register pins led out of the rotatably mounted cylinder must become.
Dies kann in einfacher Weise durch einen Drehübertrager (z.B. Schleifringübertrager) geschehen. Dieser setzt jedoch an einem stirnseitigen Ende des Zylinders bzw. des Zylinderzapfens entsprechenden Bauraum voraus. Dieser ist gerade bei Plattenzylindern mit Einrichtungen zur Seiten- und Umfangsregisterverstellung nicht immer vorhanden - ferner verkomplizieren derartige Einrichtungen eine einfache Anbringung eines Übertragungssystems. Ein Schleifringübertrager bedingt ferner den Nachteil, daß es durch Verschmutzung der Kontakte zu Signalstörungen kommt, was wiederum Störungen im Plattenwechselvorgang hervorrufen kann (z. B. Abbruch des Wechselvorganges obwohl Druckplatte korrekt anliegt).This can easily be done using a rotary transformer (e.g. Slip ring transmitter) happen. However, this starts an end face of the cylinder or the cylinder journal appropriate space in advance. This is currently with Plate cylinders with devices for side and circumferential register adjustment not always available - further complicate such devices a simple attachment of a Transmission system. A slip ring transmitter also requires the disadvantage that it is due to contamination of the contacts Signal disturbance comes, which in turn disturbances in the plate changing process can cause (e.g. termination of the change process although pressure plate fits correctly).
Aus der DE 35 27 103 C2 ist eine Vorrichtung zum passerhaltigen Ansetzen einer Druckplatte auf einem Plattenzylinder von Rotations-Offsetdruckmaschinen bekannt, bei der den elektrisch abfragbaren Registerstiften Leuchtdioden zugeordnet sind, so daß sich der registergerechte Zustand direkt am entsprechenden Registerstift ablesen läßt. Diese Einrichtung dient aber dem manuellen Ansetzen von Druckplatten auf einem Zylinder. Eine Automatisierung eines Druckplattenwechselvorganges läßt sich damit nicht erzielen.DE 35 27 103 C2 describes a device for registering Place a printing plate on a plate cylinder from Rotary offset printing machines are known in which the electrically Queryable register pins assigned LEDs are, so that the register-correct state directly on can read the corresponding register pin. This facility but serves the manual attachment of printing plates on one Cylinder. Automation of a printing plate change process cannot be achieved with it.
Aus der EP-A 0 581 212 ist eine Einrichtung zur Registerkontrolle für Druckformen bekannt, bei welcher die korrekte Anlage einer Druckform an Registerstiften durch elektrische Signale feststellbar und an eine stationäre Steuer- und Auswerteeinheit leitbar ist. Insbesondere ist eine optische Signalübertragung mit einem am Zylinder angebrachten Sender sowie einem maschinenfest angebrachten Empfänger vorgesehen.EP-A 0 581 212 describes a device for register control for printing forms known in which the correct creation of a printing form on register pins by electrical signals can be determined and sent to a stationary control and evaluation unit is conductive. In particular, there is an optical signal transmission with one on the cylinder attached transmitter and a machine-mounted receiver intended.
Aufgabe der vorliegenden Erfindung ist es, eine Einrichtung zur Registerkontrolle gemäß dem Oberbegriff von Anspruch 1 derartig zu erweitern, so daß eine einfache und sichere Signalübertragung an eine stationäre, außerhalb des Zylinders angeordnete Steuer- und Auswerteeinheit möglich ist. Gelöst wird diese Aufgabe durch die kennzeichnenden Merkmale von Anspruch 1. Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen.The object of the present invention is a device for register control according to the preamble of claim 1 to expand in such a way that a simple and safe Signal transmission to a stationary, outside the cylinder arranged control and evaluation unit is possible. This task is solved by the characteristic features of claim 1. Developments of the invention result from the subclaims.
Gemäß der Erfindung ist vorgesehen, daß der Signalzustand der elektrisch abfragbaren Registerstifte durch wenigstens eine im Zylinder angeordnete Lichtquelle sowie wenigstens einen stationär angeordneten und der Steuer- und Auswerteeinheit vorgeordneten Lichtempfänger übermittelbar ist. Der Begriff Licht ist hier im weiteren Sinne zu verstehen, d.h. nicht nur als elektromagnetische Strahlung im sichtbaren Bereich. Demzufolge können die Lichtquelle sowie der Lichtempfänger elektromagnetische Strahlung sowohl im sichtbaren als auch im Infraroten- bzw. Ultravioletten Bereich abgeben bzw. empfangen. Bei der Verwendung von sichtbarem Licht ergibt sich als Vorteil, daß der Schaltzustand der vorzugsweise als elektrisch isoliert gegenüber dem Zylinder bzw. der Klemmschiene angeordneten Registerstifte auch beim manuellen Wechseln bzw. Ansetzen von Druckformen für eine Bedienperson erkennbar ist. In diesem Falle ist die Lichtquelle bevorzugt im Bereich der Klemmeinrichtung und vorzugsweise auch in der Nähe des entsprechenden Registerstiftes angebracht. Dabei kann vorgesehen sein, daß durch eine Lichtquelle die registergerechte Anlage der Druckformen an beiden Registerstiften gemeinsam angezeigt und an einen entsprechenden stationären Empfänger übertragen wird. Vorzugsweise wird aber der Schaltzustand der elektrisch abfragbaren Registerstifte getrennt und unterscheidbar nach A- und B-Seite einzeln abgefragt und durch entsprechende Signalgenerierung (Codierung) an den stationären Lichtempfänger übertragen. Durch die stationäre Steuer- und Auswerteeinheit ist somit feststellbar, an welchem der Registerstifte die Druckform anliegt und an welchem dies nicht der Fall ist. Bei einem vollautomatischen Druckformwechsler ergibt sich dabei die Möglichkeit durch entsprechendes Ansteuern der die neue Druckform zuführenden Transportmittel eine verkantet an den Registerstiften anliegende Druckplatte in die korrekte registergerechte Position zu bringen.According to the invention it is provided that the signal state of the electrically interrogated register pins by at least one light source arranged in the cylinder and at least one stationary and the control and evaluation unit upstream light receiver is communicable. The term Here light is to be understood in a broader sense, i.e. not only as electromagnetic radiation in the visible range. As a result, the light source as well as the light receiver electromagnetic radiation both in the visible and in the Give or receive infrared or ultraviolet range. When using visible light, the result is: Advantage that the switching state is preferably electrical insulated from the cylinder or the clamping rail arranged register pins even when changing or Applying printing forms is recognizable for an operator. In this case, the light source is preferably in the range of Clamping device and preferably also in the vicinity of the corresponding Register pin attached. It can be provided be that the register-compliant system by a light source of the printing forms are displayed together on both register pins and transmitted to a corresponding stationary receiver becomes. However, the switching state is preferably electrical queryable register pins separated and distinguishable after A and B side queried individually and by appropriate Signal generation (coding) to the stationary light receiver transfer. Through the stationary control and evaluation unit it is therefore possible to determine which of the register pins the printing form is applied and on which this is not the case. The result is a fully automatic printing plate changer the possibility by controlling the a new form of transport supplying a cant pressure plate in contact with the register pins into the correct one to bring it into the correct position.
Die den Signalzustand der Registerstifte übertragende Lichtquelle kann stirnseitig an einer geeigneten Fläche des Zylinders angeordnet sein. Gestellfest korrespondierend im entsprechenden Abstand zur Drehachse des Zylinders ist der Lichtempfänger angeordnet, wobei die Winkelstellung der Lichtquelle am Zylinder sowie des Lichtempfängers an der Gestellwand bzw. einem vorgeordneten Träger derartig ist, daß bei stehendem Zylinder während des Einführens einer neuen Druckform der Signalzustand der Registerstifte übertragbar ist. In diesem wie auch in den noch weiter unten stehenden Ausführungsfällen erfolgt die Übertragung des Signalzustandes durch codierte Signale, d.h. die Lichtquelle wird mit einer vorgesehenen Impulsfolge (Signalcode) angesteuert. So ist es möglich, mittels nur einer Lichtquelle den Signalzustand von zwei oder auch mehreren am Zylinder angeordneten elektrisch abfragbaren Registerstifte zu übertragen. Hierzu ist der Lichtquelle ein die Signale der elektrisch abfragbaren Registerstifte einlesende und zu entsprechende Steuersignalen verarbeitender Impulserzeuger vorgeordnet. Dieser steht mit einer im Zylinder angeordneten Spannungsquelle in Verbindung, welcher als eine Batterie mit hoher Lebensdauer bzw. ein wiederaufladbarer Akku ausgebildet ist.The light source transmitting the signal state of the register pins can face on a suitable surface of the cylinder be arranged. Corresponding to the frame Distance to the axis of rotation of the cylinder is Light receiver arranged, the angular position of the Light source on the cylinder and the light receiver on the Rack wall or an upstream support is such that with the cylinder stationary while inserting a new one Print form of the signal state of the register pins can be transferred is. In this as well as in the further In the cases below, the signal state is transmitted by coded signals, i.e. the light source will controlled with an intended pulse sequence (signal code). It is thus possible to determine the signal state using only one light source of two or more arranged on the cylinder to transmit electrically interrogable register pins. For this the light source is the signals of the electrically interrogable Control pins reading in and corresponding control signals upstream processing pulse generator. This stands in with a voltage source arranged in the cylinder Connection, which as a long life battery or a rechargeable battery is formed.
Bei einer anderen Ausführungsform der Erfindung kann vorgesehen sein, ein oder mehrere Lichtquellen beispielsweise im Bereich der Registerstifte anzubringen. Die die Signale dieser Lichtquellen detektierenden Lichtempfänger sind dann im Umfangsbereich des Zylinders gestellfest angeordnet, wobei die Position derartig gewählt ist, daß in einer Winkelstellung des Zylinders, in welcher das Zuführen einer neuen Druckform erfolgt, die entsprechenden Signale der Lichtquellen von den Lichtempfängern empfangen werden können. Wird für die Signalübertragung sichtbares Licht verwendet, so ist es bei entsprechender Anordnung und Ausbildung der Lichtquellen möglich, daß beim manuellen Zuführen einer Druckform auch eine Bedienperson die registergerechte Anlage überprüfen kann. Bevorzugt ist dann jedem elektrisch abfragbaren Registerstift eine Lichtquelle beispielsweise in Form einer Leuchtdiode zugeordnet.In another embodiment of the invention can be provided be one or more light sources for example in the The area of the register pins. The the signals of these light source-detecting light receivers arranged fixed to the frame in the peripheral region of the cylinder, wherein the position is chosen such that in an angular position of the cylinder in which the feeding of a new one Printing form takes place, the corresponding signals of the light sources can be received by the light receivers. Is for the signal transmission uses visible light, so it is with appropriate arrangement and design of the light sources possible that when manually feeding a printing form an operator check the register-correct system can. Each electrically interrogable register pin is then preferred a light source, for example in the form of a Assigned to LED.
Auch ist es möglich, für jeden elektrisch abfragbaren Registerstift eine separate Lichtquelle beispielsweise an einem Ende des Zylinders (der Zylindergrube) anzuordnen und einen stationären Lichtempfänger bzw. entsprechend der Anzahl der Lichtquellen mehrere Lichtempfänger in einer der Position des Zylinders beim Druckformwechsel entsprechenden Lage stationär anzuordnen. Auch bei einer derartigen Anordnung ist es möglich, daß die Signale der Lichtquellen sowohl von einer Bedienperson visuell ausgewertet als auch an den stationären Lichtempfänger übertragen werden.It is also possible for each register pin that can be queried electrically a separate light source, for example on one End of the cylinder (the cylinder pit) and one stationary light receiver or according to the number of Light sources multiple light receivers in one of the position of the Cylinder stationary when changing printing form to arrange. With such an arrangement it is also possible that the signals from the light sources come from both Operator evaluated visually as well as on the stationary Light receivers are transmitted.
Sollen die am Zylinder angebrachten Lichtquellen sowohl zur visuellen Auswertung der registergerechten Anlage als auch zur Signalübertragung an den stationären Lichtempfänger verwendet werden, so sind im sichtbaren Licht aussendende Lichtquellen (Leuchtdioden) zu verwenden. Eine codierte Signalübertragung ist durch entsprechende Wahl der Frequenz und Impulslänge möglich. So kann der registergerechte Anlagezustand beispielsweise dadurch übertragen werden, daß die Lichtquelle (Leuchtdiode) impulsweise angesteuert wird, wobei die Frequenz so gewählt ist, daß sich für den Beobachter ein stationären Leuchtzustand ergibt.Should the light sources attached to the cylinder be used both for visual evaluation of the register-compliant system as well for signal transmission to the stationary light receiver are used, are emitting in visible light Use light sources (light emitting diodes). A coded one Signal transmission is through appropriate choice of frequency and pulse length possible. So the register-correct system condition are transmitted, for example, in that the Light source (light emitting diode) is driven in pulses, whereby the frequency is chosen so that the observer stationary steady state results.
