Definitions
- the invention relates to a device for register control according to the preamble of claim 1.
- the printing forms or printing plates are held on the form or plate cylinder with a clamping device assigned to the beginning and the end of printing.
- a clamping device assigned to the beginning and the end of printing.
- the registration-correct overprinting of the individual colors by the individual printing forms is of crucial importance.
- the individual printing formes must be positioned precisely on the form or plate cylinder.
- numerous register systems have been developed, which consist, for example, of pins or stops arranged in the start-of-printing clamping device, which interact with punchings made on the corresponding edge of the printing form or printing plate.
- register pins or register stops are designed so that they can be queried electrically. This can be done in a simple manner in that the register pins or the stops are arranged in an electrically insulated manner with respect to the clamping rail or the cylinder, so that an electrical circuit is closed by the register-correct installation of the printing form or printing plate.
- the register-correct system can be displayed, for example, by means of lamps (light-emitting diodes) attached to the cylinder or the register stops. Such a configuration is particularly suitable for visual inspection of printing forms to be applied by hand to the cylinder.
- the signal of the register query is to be evaluated by a control in order to close the corresponding clamping rail for fastening the plate after feeding in a new printing plate and establishing the register-correct system.
- the signal evaluating control which causes the rail to close and triggers the further processes of the changing process, is arranged outside the plate or printing form cylinder, so that the signal of the electrically interrogable register pins must be routed out of the rotatably mounted cylinder.
- a slip ring transmitter also has the disadvantage that the contacts are contaminated by signal interference, which in turn can cause disruptions in the plate changing process (e.g. termination of the changing process although the pressure plate is correctly applied).
- the object of the present invention is to expand a device for register control according to the preamble of claim 1 in such a way that simple and reliable signal transmission to a stationary control and evaluation unit arranged outside the cylinder is possible.
- the signal state of the electrically interrogable register pins can be transmitted by at least one light source arranged in the cylinder and at least one light receiver arranged in a stationary manner and arranged upstream of the control and evaluation unit.
- the term light is to be understood here in a broader sense, ie not only as electromagnetic radiation in the visible range.
- the light source and the light receiver can emit or receive electromagnetic radiation both in the visible and in the infrared or ultraviolet range.
- the advantage of using visible light is that the switching state of the register pins, which are preferably arranged as electrically insulated from the cylinder or the clamping rail, can also be recognized by an operator when manually changing or applying printing forms.
- the light source is preferably mounted in the area of the clamping device and preferably also in the vicinity of the corresponding register pin. It can be provided that the register-correct installation of the printing forms on both register pins is displayed together by a light source and transmitted to a corresponding stationary receiver. However, the switching state of the electrically interrogable register pins is preferably queried separately and distinguishably from the A and B sides and transmitted to the stationary light receiver by means of appropriate signal generation (coding). The stationary control and evaluation unit can thus determine which of the register pins the printing form is in and which it is not. In the case of a fully automatic printing form changer, this is possible by appropriately controlling the means of transporting the new printing form to bring a canted printing plate into the correct register-correct position.
- the light source which transmits the signal state of the register pins can be arranged on the end face on a suitable surface of the cylinder.
- the light receiver is arranged corresponding to the frame at a corresponding distance from the axis of rotation of the cylinder, the angular position of the light source on the cylinder and of the light receiver on the frame wall or an upstream support being such that the signal state of the register pins can be transmitted when the cylinder is stationary while a new printing form is being inserted is.
- the signal state is preferably transmitted by coded signals, i.e. the light source is controlled with a provided pulse sequence (signal code).
- the light source is preceded by a pulse generator which reads in the signals of the electrically interrogable register pins and processes them into corresponding control signals.
- a pulse generator which reads in the signals of the electrically interrogable register pins and processes them into corresponding control signals.
- This is connected to a voltage source arranged in the cylinder, which is designed as a battery with a long service life or a rechargeable battery.
- one or more light sources can be provided, for example in the area of the register pins.
- the light receivers which detect the signals from these light sources are then arranged fixed to the frame in the peripheral region of the cylinder, the position being selected such that the corresponding signals from the light sources can be received by the light receivers in an angular position of the cylinder in which the feeding of a new printing form takes place .
- Is for the signal transmission uses visible light, it is possible with an appropriate arrangement and design of the light sources that an operator can also check the register-correct system when manually feeding a printing form.
- a light source for example in the form of a light-emitting diode, is then preferably assigned to each electrically interrogable register pin.
- a separate light source for each electrically interrogated register pin for example at one end of the cylinder (the cylinder pit) and to arrange a stationary light receiver or, depending on the number of light sources, several light receivers in a position corresponding to the position of the cylinder when changing the printing form. Even with such an arrangement, it is possible for the signals from the light sources to be evaluated visually by an operator and also to be transmitted to the stationary light receiver.
- the light sources attached to the cylinder are to be used both for visual evaluation of the register-compliant system and for signal transmission to the stationary light receiver, then light sources emitting in visible light (light-emitting diodes) should be used. Coded signal transmission is possible by choosing the appropriate frequency and pulse length.
- the register-correct system state can be transmitted, for example, by driving the light source (light-emitting diode) in pulses, the frequency being selected so that the observer has a steady state of light.
- a cylinder 1 designed as a forme or plate cylinder two electrically interrogable register pins 2.1, 2.2 are arranged axially spaced from one another.
- these register pins 2.1, 2.2 are arranged as electrically insulated from the clamping rail or cylinder 1, so that they act as switches which can be actuated by contact with the printing plate (metallic printing plate / printing form).
- the register pins 2.1, 2.2 are shown as switches.
- the switching signals of the electrically interrogable register pins 2.1, 2.2 can be fed to a driver 4 arranged in the cylinder 1, which is followed by a light source 5 in the form of a light-emitting diode or a light source designed in another way.
- the signal driver 4 is connected to a voltage source arranged in the cylinder 1 in the form of a battery or an accumulator.
- the light source 5 is arranged on the end face on a surface of the cylinder 1.
- a light control 6, for example in the form of a photo transistor and a driver 7 is connected upstream of a stationary control and evaluation unit 8.
- the light source 5 is driven by the driver 4 to generate the signals representing this state, so that the light signals of the light source 5 in the corresponding position of the cylinder 1 via the light receiver 6 and the downstream driver 7 of the control and evaluation unit 8 can be supplied as electrical signals are.
- the electrically interrogable register pins 2.1, 2.2 in the cylinder 1 are assigned individual light sources 5.1, 5.2.
- the switching status of the register pins 2.1, 2.2 is displayed or transmitted by the respectively assigned light source 5.1, 5.2.
- the representation of the cylinder 1 with the register pins 2.1, 2.2 arranged therein and the associated light sources 5.1, 5.2 corresponds to a view from above and is purely in principle.
- a position of the cylinder 1 (which is used to change the printing form) is assigned to the light sources 5.1, 5.2 of the register pins 2.1, 2.2, light receivers 6.1, 6.2 fixed to the frame, the signals of which are supplied to the control and evaluation unit 8 via drivers 7.1, 7.2.
- the arrangement of the light sources 5.1, 5.2 on the cylinder 1 or the register pins 2.1, 2.2 can be such that they can also be observed visually, that is to say can also be used when changing the printing form manually. As a result, the light sources 5.1, 5.2 emit visible light.
- FIG. 3 shows, like FIG. 2, a basic plan view of a cylinder 1 with register pins 2.1, 2.2 arranged therein.
- the light sources 5.1, 5.2 are attached to a front end of the cylinder 1.
- Each register pin 2.1, 2.2 is assigned a light source 5.1, 5.2, such that the switching status of one of the register pins 2.1, 2.2 can be displayed and transmitted by a light source 5.1, 5.2.
- the light sources 5.1, 5.2 are assigned to the frame (in a position of the cylinder 1 intended for changing the printing form) light receivers 6.1, 6.2 and drivers 7.1, 7.2, the signals of which can be fed to the stationary control and evaluation unit 8.

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
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 presses and in particular sheetfed offset printing presses, the printing forms or printing plates are held on the form or plate cylinder with a clamping device assigned to the beginning and the end of printing. For the quality of multi-color printing, the registration-correct overprinting of the individual colors by the individual printing forms is of crucial importance. As a result, the individual printing formes must be positioned precisely on the form or plate cylinder. For this purpose, numerous register systems have been developed, which consist, for example, of pins or stops arranged in the start-of-printing clamping device, which interact with punchings made on the corresponding edge of the printing form or printing 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.Devices for register control are known in which the register pins or register stops are designed so that they can be queried electrically. This can be done in a simple manner in that the register pins or the stops are arranged in an electrically insulated manner with respect to the clamping rail or the cylinder, so that an electrical circuit is closed by the register-correct installation of the printing form or printing plate. The register-correct system can be displayed, for example, by means of lamps (light-emitting diodes) attached to the cylinder or the register stops. Such a configuration is particularly suitable for visual inspection of 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.In the case of semiautomatic or fully automatic printing plate changers, the signal of the register query is to be evaluated by a control in order to close the corresponding clamping rail for fastening the plate after feeding in a new printing plate and establishing the register-correct system. The the The signal evaluating control, which causes the rail to close and triggers the further processes of the changing process, is arranged outside the plate or printing form cylinder, so that the signal of the electrically interrogable register pins must be routed out of the rotatably mounted cylinder.
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 transformer). However, this requires corresponding installation space at an end face of the cylinder or the cylinder journal. This is not always present, especially in plate cylinders with devices for adjusting the lateral and circumferential registers. Furthermore, such devices complicate the simple attachment of a transmission system. A slip ring transmitter also has the disadvantage that the contacts are contaminated by signal interference, which in turn can cause disruptions in the plate changing process (e.g. termination of the changing process although the pressure plate is correctly applied).
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.From DE 35 27 103 C2 a device for registering a printing plate on a plate cylinder of rotary offset printing presses is known, in which light-emitting diodes are assigned to the register pins that can be queried electrically, so that the register-correct state can be read directly from the corresponding register pin. However, this device is used for the manual attachment of printing plates on a cylinder. Automation of a printing plate changing process cannot be achieved with this.
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.The object of the present invention is to expand a device for register control according to the preamble of
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
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 interrogable register pins can be transmitted by at least one light source arranged in the cylinder and at least one light receiver arranged in a stationary manner and arranged upstream of the control and evaluation unit. The term light is to be understood here in a broader sense, ie not only as electromagnetic radiation in the visible range. As a result, the light source and the light receiver can emit or receive electromagnetic radiation both in the visible and in the infrared or ultraviolet range. The advantage of using visible light is that the switching state of the register pins, which are preferably arranged as electrically insulated from the cylinder or the clamping rail, can also be recognized by an operator when manually changing or applying printing forms. In this case, the light source is preferably mounted in the area of the clamping device and preferably also in the vicinity of the corresponding register pin. It can be provided that the register-correct installation of the printing forms on both register pins is displayed together by a light source and transmitted to a corresponding stationary receiver. However, the switching state of the electrically interrogable register pins is preferably queried separately and distinguishably from the A and B sides and transmitted to the stationary light receiver by means of appropriate signal generation (coding). The stationary control and evaluation unit can thus determine which of the register pins the printing form is in and which it is not. In the case of a fully automatic printing form changer, this is possible by appropriately controlling the means of transporting the new printing form to bring a canted printing plate into the correct register-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. Bevorzugt erfolgt in diesem wie auch in den noch weiter unten stehenden Ausführungsfällen 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 which transmits the signal state of the register pins can be arranged on the end face on a suitable surface of the cylinder. The light receiver is arranged corresponding to the frame at a corresponding distance from the axis of rotation of the cylinder, the angular position of the light source on the cylinder and of the light receiver on the frame wall or an upstream support being such that the signal state of the register pins can be transmitted when the cylinder is stationary while a new printing form is being inserted is. In this as well as in the embodiments below, the signal state is preferably transmitted by coded signals, i.e. the light source is controlled with a provided pulse sequence (signal code). It is thus possible to transmit the signal state of two or more electrically interrogable register pins arranged on the cylinder using only one light source. For this purpose, the light source is preceded by a pulse generator which reads in the signals of the electrically interrogable register pins and processes them into corresponding control signals. This is connected to a voltage source arranged in the cylinder, which is designed as a battery with a long service life or a rechargeable battery.
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, one or more light sources can be provided, for example in the area of the register pins. The light receivers which detect the signals from these light sources are then arranged fixed to the frame in the peripheral region of the cylinder, the position being selected such that the corresponding signals from the light sources can be received by the light receivers in an angular position of the cylinder in which the feeding of a new printing form takes place . Is for the signal transmission uses visible light, it is possible with an appropriate arrangement and design of the light sources that an operator can also check the register-correct system when manually feeding a printing form. A light source, for example in the form of a light-emitting diode, is then preferably assigned to each electrically interrogable register pin.
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 to arrange a separate light source for each electrically interrogated register pin, for example at one end of the cylinder (the cylinder pit) and to arrange a stationary light receiver or, depending on the number of light sources, several light receivers in a position corresponding to the position of the cylinder when changing the printing form. Even with such an arrangement, it is possible for the signals from the light sources to be evaluated visually by an operator and also to be transmitted to the stationary light receiver.
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.If the light sources attached to the cylinder are to be used both for visual evaluation of the register-compliant system and for signal transmission to the stationary light receiver, then light sources emitting in visible light (light-emitting diodes) should be used. Coded signal transmission is possible by choosing the appropriate frequency and pulse length. The register-correct system state can be transmitted, for example, by driving the light source (light-emitting diode) in pulses, the frequency being selected so that the observer has a steady state of light.

In einem als Form- bzw. Plattenzylinder ausgebildeten Zylinder 1 sind axial voneinander beabstandet zwei elektrisch abfragbare Registerstifte 2.1, 2.2 angeordnet. Bei diesem Ausführungsbeispiel sei angenommen, daß diese Registerstifte 2.1, 2.2 als elektrisch isoliert gegenüber der Klemmschiene bzw. dem Zylinder 1 angeordnet sind, so daß diese als durch Kontakt mit der Druckplatte (metallische Druckplatte / Druckform) betätigbare Schalter wirken. Entsprechend sind die Registerstifte 2.1, 2.2 als Schalter dargestellt. Die Schaltsignale der elektrisch abfragbaren Registerstifte 2.1, 2.2 sind einem im Zylinder 1 angeordneten Treiber 4 zuführbar, dem eine Lichtquelle 5 in Form einer Leuchtdiode oder eines in anderer Weise ausgebildeten Leuchtmittels nachgeschaltet ist.

Bei der gemäß Figur 1 angedeuteten Ausführungsvariante ist die Lichtquelle 5 stirnseitig an einer Fläche des Zylinders 1 angeordnet. Gestellfest und in einem geeigneten Abstand dazu ist einer stationären Steuer- und Auswerteeinheit 8 ein Lichtempfänger 6 beispielsweise in Form eines Fototransistors nebst einem Treiber 7 vorgeschaltet. Bei einer registergerechten Anlage der nicht dargestellten Druckform an den Registerstiften 2.1, 2.2 (entsprechende Kontakte geschlossen) wird die Lichtquelle 5 durch den Treiber 4 zur Erzeugung der diesen Zustand repräsentierenden Signale angesteuert, so daß die Lichtsignale der Lichtquelle 5 in der entsprechenden Stellung des Zylinders 1 über den Lichtempfänger 6 und den nachgeschalteten Treiber 7 der Steuer- und Auswerteeinheit 8 als elektrische Signale zuführbar sind.In the embodiment variant indicated according to FIG. 1, the

Die Anordnung der Lichtquellen 5.1, 5.2 am Zylinder 1 bzw. den Registerstiften 2.1, 2.2 kann dabei derartig sein, daß diese auch visuell beobachtbar sind, also auch bei einem manuellen Druckformwechsel verwendbar sind. Demzufolge senden die Lichtquellen 5.1, 5.2 sichtbares Licht aus.A position of the cylinder 1 (which is used to change the printing form) is assigned to the light sources 5.1, 5.2 of the register pins 2.1, 2.2, light receivers 6.1, 6.2 fixed to the frame, the signals of which are supplied to the control and
