Mit Hilfe der Übertragungseinrichtung können ein Fluid, elektrische Signale und / oder elektrische Energie je nach gewünschter Anwendung effizient zwischen Druckplattenzylinder und dann hierauf angeordneter Druckhülse übertragen werden. Insbesondere ist es hierdurch ermöglicht, die Druckhülse mit dem Fluid, den elektrischen Signalen und / oder der elektrischen Energie zu versorgen, weshalb mit der Übertragungseinrichtung eine Versorgungseinrichtung bereitgestellt sein kann. Das Verbindungselement kann dann auch als Versorgungselement bezeichnet werden.With the help of the transmission device, a fluid, electrical signals and/or electrical energy can be efficiently transmitted between the printing plate cylinder and the printing sleeve arranged thereon, depending on the desired application. In particular, this makes it possible to supply the printing sleeve with the fluid, the electrical signals and/or the electrical energy, which is why a supply device can be provided with the transmission device. The connecting element can then also be referred to as a supply element.
Die Übertragungsverbindung kann eingerichtet sein, zum Beispiel elektrische und / oder optische Signale zu übertragen. Beispielweise können Mess- und / oder Steuersignale übertragen werden.The transmission connection can be set up to transmit, for example, electrical and/or optical signals. For example, measurement and/or control signals can be transmitted.
Das Verbindungselement kann mit einem versenkbaren Verbindungselement an dem Zylinderkörper gebildet sein, welches in der eingefahrenen Stellung in Bezug auf die Außenfläche nicht überstehend angeordnet ist. Das versenkbare Verbindungselement ist hier an dem Zylinderkörper gebildet oder angeordnet. Beim Übergang zwischen der eingefahrenen Stellung zu der ausgefahrenen Stellung wird dann die Übertragungsverbindung zwischen Druckplattenzylinder und Druckhülse hergestellt. Die Außenfläche des Zylinderkörpers kann Teil einer Mantelfläche des Zylinderkörpers sein. Das versenkbare Verbindungselement kann in der eingefahrenen Stellung gegenüber einer Öffnungsfläche einer Öffnung, in welcher das Verbindungselement verlagerbar angeordnet ist, zurückstehen.The connecting element can be formed with a retractable connecting element on the cylinder body, which in the retracted position is not arranged so as to protrude from the outer surface. The retractable connecting element is formed or arranged on the cylinder body. During the transition between the retracted position and the extended position, the transmission connection between the printing plate cylinder and the printing sleeve is then established. The outer surface of the cylinder body can be part of a jacket surface of the cylinder body. In the retracted position, the retractable connecting element can protrude from an opening surface of an opening in which the connecting element is arranged so as to be displaceable.
Das versenkbare Verbindungselement kann in der ausgefahrenen Stellung in Bezug auf die Außenfläche überstehend angeordnet sein. Während das versenkbare Verbindungselement in der eingefahrenen Stellung, die auch als Ruhestellung bezeichnet werden kann, nicht über die Außenfläche des Zylinderkörpers übersteht, ändert sich dies in der ausgefahrenen Stellung, die auch als Aktiv- oder Arbeitsstellung bezeichnet werden kann, dahingehend, dass das versenkbare Verbindungselement über die Außenfläche übersteht.In the extended position, the retractable connecting element can be arranged to protrude from the outer surface. While the retractable connecting element does not protrude from the outer surface of the cylinder body in the retracted position, which can also be referred to as the rest position, this changes in the extended position, which can also be referred to as the active or working position, in that the retractable connecting element protrudes from the outer surface.
Zwischen dem Druckplattenzylinder und der Druckhülse kann ein Spalt ausgebildet sein, und der Spalt kann mit der in der ausgefahrenen Stellung des Verbindungselements ausgebildeten Übertragungsverbindung überbrückt sein.A gap may be formed between the printing plate cylinder and the printing sleeve, and the gap can be bridged by the transmission connection formed in the extended position of the connecting element.
Der Spalt kann zum Beispiel zwischen der Außenfläche des Druckplattenzylinders und der Innenfläche der Druckhülse ausgebildet sein.The gap can, for example, be formed between the outer surface of the printing plate cylinder and the inner surface of the printing sleeve.
Der Spalt ist so mit Hilfe der Übertragungseinrichtung überbrückbar, insbesondere wenn die Druckhülse auf dem Druckplattenzylinder in der Endstellung oder-position angeordnet ist. Das Verbindungselement kann dann aus der eingefahrenen Stellung in die ausgefahrene Stellung verlagert werden, um so die Übertragungsverbindung, den Spalt zwischen dem Zylinderkörper / der Außenfläche des Zylinderkörpers und Innenfläche der Druckhülse oder einen Spalt innerhalb des Druckplattenzylinders zur Innenfläche der Druckhülse überbrückend, auszubilden, so dass die Übertragung eines Fluids, von elektrischen Signalen und / oder von elektrischer Energie mittels der Übertragungsverbindung ermöglicht ist. Hierbei oder in anderen Ausführungen kann die Übertragungsverbindung für eine (wahlweise unidirektionale) Übertragung von dem Druckplattenzylinder zur Druckhülse hin, von der Druckhülse zum Druckplattenzylinder hin oder eine bidirektionale Übertragung zwischen Druckplattenzylinder und Druckhülse eingerichtet sein. In Verbindung mit dem Fluid kann eine unidirektionale Übertragung beispielsweise mit einem Einwegventil in einer Fluidverbindung zwischen Druckplattenzylinder und Druckhülse ausgebildet sein.The gap can thus be bridged with the aid of the transmission device, in particular when the printing sleeve is arranged on the printing plate cylinder in the end position. The connecting element can then be moved from the retracted position to the extended position in order to form the transmission connection, bridging the gap between the cylinder body/the outer surface of the cylinder body and the inner surface of the printing sleeve or a gap within the printing plate cylinder to the inner surface of the printing sleeve, so that the transmission of a fluid, electrical signals and/or electrical energy is possible by means of the transmission connection. Here or in other embodiments, the transmission connection can be set up for (optionally unidirectional) transmission from the printing plate cylinder to the printing sleeve, from the printing sleeve to the printing plate cylinder or a bidirectional transmission between the printing plate cylinder and the printing sleeve. In connection with the fluid, a unidirectional transmission can be formed, for example with a one-way valve in a fluid connection between the printing plate cylinder and the printing sleeve.
Die Größe des Spaltes zwischen Druckplattenzylinder und Druckhülse kann etwa 0,001 mm bis mehrere Millimeter betragen.The size of the gap between the printing plate cylinder and the printing sleeve can be about 0.001 mm to several millimeters.
Das versenkbare Verbindungselement kann in der ausgefahrenen Stellung in Bezug auf die Außenfläche überstehend und den Spalt überbrückend angeordnet sein. Während das versenkbare Verbindungselement hierbei in der eingefahrenen Stellung nicht über die Außenfläche des Zylinderkörpers übersteht, ändert sich dies in der ausgefahrenen Stellung dahingehend, dass das versenkbare Verbindungselement über die Außenfläche übersteht und so den Spalt überbrückt.In the extended position, the retractable connecting element can be arranged to protrude from the outer surface and bridge the gap. While the retractable connecting element does not protrude from the outer surface of the cylinder body in the retracted position, this changes in the extended position in that the retractable connecting element protrudes from the outer surface and thus bridges the gap.
Der Spalt oder ein Abstand kann in einer alternativen Ausführung nur zwischen einer Spitze des Verbindungselementes und der äußeren umlaufenden Oberfläche des Druckplattenzylinder ausgebildet sein. Die Spitze des Verbindungselementes kann dann an ein Innenrohr der Druckhülse an einer Bohrung andocken. Das versenkbare Verbindungselement kann dann in der ausgefahrenen Stellung den Abstand (Spalt) überbrücken, welcher in der eingefahrenen (zurückgefahrenen) Stellung des Verbindungselementes zwischen Spitze des Verbindungselementes und der Außenfläche des Druckplattenzylinders ausgebildet ist.In an alternative embodiment, the gap or a distance can be formed only between a tip of the connecting element and the outer circumferential surface of the printing plate cylinder. The tip of the connecting element can then dock onto an inner tube of the printing sleeve at a bore. The retractable connecting element can then bridge the distance (gap) in the extended position, which in the retracted position (retracted) position of the connecting element between the tip of the connecting element and the outer surface of the printing plate cylinder.
Es kann ein druckhülsenseitiger Kanal vorgesehen sein, welcher in der Druckhülse mit der druckhülsenseitigen Anschlussstelle verbunden ist. Alternativ oder ergänzend kann ein druckplattenzylinderseitiger Kanal vorgesehen sein, welcher in dem Zylinderkörper gebildet und mit der druckplattenzylinderseitigen Anschlussstelle verbunden ist. Ist das Verbindungselement in der ausgefahrenen Stellung angeordnet, steht dieses mit den Anschlussstellen druckplattenzylinderseitig und druckhülsenseitig und somit mit zumindest einem der Kanäle in funktioneller Verbindung, so dass zumindest eine der Übertragungsarten ausführbar ist.A channel can be provided on the pressure sleeve side, which is connected in the pressure sleeve to the connection point on the pressure sleeve side. Alternatively or additionally, a channel can be provided on the pressure plate cylinder side, which is formed in the cylinder body and connected to the connection point on the pressure plate cylinder side. If the connecting element is arranged in the extended position, it is functionally connected to the connection points on the pressure plate cylinder side and the pressure sleeve side and thus to at least one of the channels, so that at least one of the transmission types can be carried out.
Das Verbindungselement kann einen Elementkanal aufweisen, der eingerichtet ist, sich zumindest in der ausgefahrenen Stellung des Verbindungselements mit dem druckplattenzylinderseitigen Kanal und / oder dem druckhülsenseitigen Kanal zu verbinden. Auf diese Weise ist über das Verbindungselement eine jeweilige Kanalverbindung druckplattenzylinderseitig sowie druckhülsenseitig ausbildbar. Der Elementkanal kann eingerichtet sein, zumindest in der ausgefahrenen Stellung, den Spalt zu überbrücken.The connecting element can have an element channel that is designed to connect to the channel on the printing plate cylinder side and/or the channel on the printing sleeve side, at least in the extended position of the connecting element. In this way, a respective channel connection can be formed on the printing plate cylinder side and on the printing sleeve side via the connecting element. The element channel can be designed to bridge the gap, at least in the extended position.
Der Elementkanal, der druckplattenzylinderseitige Kanal und / oder der druckhülsenseitige Kanal können wenigstens einer der folgenden Kanalarten entsprechend ausgebildet sein: Fluidkanal, Leitungskanal und Kabelkanal. Der Fluidkanal ist eingerichtet, zum Übertragen des Fluids von diesem durchströmt zu werden (Strömungskanal). Der Leitungskanal ist eingerichtet, zumindest Signale zu übertragen, zum Beispiel zur Datenübertragung (Datensignalkanal) und kann hierfür Übertragungselemente aus zum Beispiel elektrisch leitendem Material aufweisen. Auch eine optische Übertragung von Signalen kann vorgesehen sein. Der Kabelkanal ist eingerichtet, ein oder mehrere Leitungen oder Kabel aufzunehmen, die der Übertragung der Signale und / oder der elektrischen Energie dienen können.The element channel, the printing plate cylinder-side channel and/or the printing sleeve-side channel can be designed according to at least one of the following channel types: fluid channel, line channel and cable channel. The fluid channel is designed to be flowed through by the fluid for transferring the fluid (flow channel). The line channel is designed to at least transfer signals, for example for data transfer (data signal channel) and can have transmission elements made of, for example, electrically conductive material for this purpose. Optical transmission of signals can also be provided. The cable channel is designed to accommodate one or more lines or cables that can be used to transfer the signals and/or the electrical energy.
Die druckplattenzylinderseitige Anschlussstelle, die druckhülsenseitige Anschlussstelle und das Verbindungselement können eingerichtet sein, eine fluidleitende Verbindung auszubilden, zum Beispiel zum Übertragen von Luft. In einer Ausgestaltung sind die druckplattenzylinderseitige Anschlussstelle, die druckhülsenseitige Anschlussstelle und das Verbindungselement eingerichtet, eine den Spalt überbrückende fluidleitende Verbindung auszubilden.The connection point on the printing plate cylinder side, the connection point on the printing sleeve side and the connecting element can be designed to form a fluid-conducting connection, for example for transmitting air. In one embodiment, the connection point on the printing plate cylinder side, the connection point on the printing sleeve side and the connecting element are designed to form a fluid-conducting connection that bridges the gap.
Die druckplattenzylinderseitige Anschlussstelle, die druckhülsenseitige Anschlussstelle und das Verbindungselement können eingerichtet sein, eine elektrisch leitende Verbindung auszubilden. Zum Ausbilden der elektrisch leitenden Verbindung können druckplattenzylinderseitig und drückhülsenseitig Elemente aus elektrisch leitendem Material mittels des Verbindungselements elektrisch leitend verbunden werden. Die druckplattenzylinderseitige Anschlussstelle, die druckhülsenseitige Anschlussstelle und das Verbindungselement können in einer Ausgestaltung eingerichtet sein, eine den Spalt überbrückende elektrisch leitende Verbindung auszubilden.The printing plate cylinder-side connection point, the printing sleeve-side connection point and the connecting element can be designed to form an electrically conductive connection To form the electrically conductive connection, elements made of electrically conductive material can be connected in an electrically conductive manner on the printing plate cylinder side and the printing sleeve side by means of the connecting element. The connection point on the printing plate cylinder side, the connection point on the printing sleeve side and the connecting element can be designed in one embodiment to form an electrically conductive connection that bridges the gap.
Das Verbindungselement kann mit der druckplattenzylinderseitigen Anschlussstelle und / oder der druckhülsenseitigen Anschlussstelle über ein jeweiliges Dichtungselement verbunden sein. Mit Hilfe des Dichtungselements kann jeweils zum Beispiel eine fluiddichte Verbindung ausgebildet sein.The connecting element can be connected to the connection point on the printing plate cylinder side and/or the connection point on the printing sleeve side via a respective sealing element. With the help of the sealing element, a fluid-tight connection can be formed in each case, for example.
Der Spalt kann sich zwischen dem Druckplattenzylinder und der Druckhülse in Bezug auf den Zylinderkörper entlang wenigsten einer der folgenden Richtungen erstrecken: Axialrichtung und Radialrichtung. Die Übertragungsverbindung kann im Wesentlichen quer zur Erstreckungsrichtung des Spalts ausgebildet werden, so dass sich die Übertragungsverbindung in radialer Richtung erstreckt, wenn der Spalt in Axialrichtung verläuft. Alternativ erstreckt sich die Übertragungsverbindung in axialer Richtung, wenn der Spalt in radialer Richtung verläuft.The gap may extend between the printing plate cylinder and the printing sleeve with respect to the cylinder body along at least one of the following directions: axial direction and radial direction. The transfer connection may be formed substantially transversely to the direction of extension of the gap, so that the transfer connection extends in the radial direction when the gap extends in the axial direction. Alternatively, the transfer connection extends in the axial direction when the gap extends in the radial direction.
Das Verbindungselement kann zum Verlagern zwischen der eingefahrenen und der ausgefahrenen Stellung in Bezug auf den Zylinderkörper entlang wenigsten einer der folgenden Richtungen verlagerbar sein: Axialrichtung und Radialrichtung.The connecting element can be displaceable for displacement between the retracted and the extended position with respect to the cylinder body along at least one of the following directions: axial direction and radial direction.
Der Druckplattenzylinder kann eingerichtet sein für eine Verwendung in einer Rotationsdruckmaschine, insbesondere einer Flexodruckmaschine. Auch kann der Druckplattenzylinder eingerichtet sein, für eine Verwendung in einer Offsetdruckmaschine, einer Tiefdruckmaschine oder Digitaldruckmaschine. Beim Flexodruck handelt es sich um ein direktes Hochdruckverfahren, bei dem flexible Druckplatten / Drückhülsen aus Photopolymer oder Gummi auf Adaptern oder Sleeves zum Einsatz kommen. Mit Hilfe des Flexodrucks lassen sich viele Materialien wie zum Beispiel Folien, Papier, Karton oder dergleichen bedrucken, die mit anderen Druckverfahren nicht oder nur eingeschränkt zu bedrucken sind.The printing plate cylinder can be set up for use in a rotary printing machine, in particular a flexographic printing machine. The printing plate cylinder can also be set up for use in an offset printing machine, a gravure printing machine or a digital printing machine. Flexographic printing is a direct relief printing process in which flexible printing plates/pressing sleeves made of photopolymer or rubber are used on adapters or sleeves. Flexographic printing can be used to print on many materials such as foils, paper, cardboard or the like that cannot be printed on with other printing processes or can only be printed on to a limited extent.
Ist die Übertragungsverbindung für eine Druckluftversorgung eingerichtet, kann vorgesehen sein, dass die Ausgangsöffnung des Verbindungs- oder Versorgungselements kleiner als eine Eingangsöffnung einer Luftzuführung innerhalb des Druckplattenzylinders ist. Hierdurch kann gewährleistet werden, dass eine ausreichend große (Axial-)Kraft bereitstellbar ist, um das Verbindungs- oder Versorgungselement aus dem Zylinderkörper in die ausgefahrene Stellung herausfahren zu lassen. So kann zum Beispiel eine ausreichend hohe Kolbenkraft des Verbindungselements vorliegen, damit eine Rückstellfeder innerhalb der Verbindungs- oder Versorgungseinrichtung zusammengedrückt wird und das Verbindungselement mit der Druckhülse zum Beispiel möglichst luftdicht in Verbindung stehen kann.If the transmission connection is set up for a compressed air supply, it can be provided that the outlet opening of the connection or supply element is smaller than an inlet opening of an air supply within the printing plate cylinder. This can ensure that a sufficiently large (axial) force can be provided to To allow the connecting or supply element to move out of the cylinder body into the extended position. For example, the piston force of the connecting element can be sufficiently high so that a return spring within the connecting or supply device is compressed and the connecting element can be connected to the pressure sleeve as airtight as possible.
Das Verlagern des Verbindungselements aus der eingefahrenen in die ausgefahrene Stellung kann gegen eine Rückstellkraft einer Rückstelleinrichtung ausgeführt werden. Mit Hilfe der Rückstellkraft kann das Verbindungselement in einer Ausgestaltung selbsttätig aus der ausgefahrenen in die eingefahrene Stellung zurückkehren. Die Rückstelleinrichtung kann beispielsweise mittels eines Federelements gebildet sein, welches eine Federrückstellkraft bereitstellt. Beispielsweise kann das Verbindungselement gegen eine Federkraft einer Spiralfeder in die ausgefahrene Stellung verlagert werden.The connection element can be moved from the retracted to the extended position against a restoring force of a restoring device. With the help of the restoring force, the connection element can automatically return from the extended to the retracted position in one embodiment. The restoring device can be formed, for example, by means of a spring element which provides a spring restoring force. For example, the connection element can be moved to the extended position against a spring force of a spiral spring.
In der Endstellung oder -position ist die Druckhülse mit Hilfe einer Registriereinrichtung auf den Zylinderkörper gesichert, beispielsweise drehfest und in axialer Richtung fixiert gelagert.In the end position, the pressure sleeve is secured to the cylinder body by means of a registration device, for example, it is mounted in a rotationally fixed manner and fixed in the axial direction.
Die Druckhülse kann lösbar auf dem Druckplattenzylinder angeordnet sein, so dass auf dem Druckplattenzylinder wahlweise unterschiedliche Druckhülsen angeordnet werden können.The printing sleeve can be detachably arranged on the printing plate cylinder so that different printing sleeves can be optionally arranged on the printing plate cylinder.
In dem Zylinderkörper des Druckplattenzylinders und / oder der Druckhülse können jeweils ein oder mehrere Innenkanäle ausgebildet sein, die mit der Übertragungseinrichtung in Verbindung stehen, zumindest dann, wenn das Übertragungselement in die ausgefahrene Stellung verlagert ist. In der eingefahrenen Stellung kann das Verbindungselement der Übertragungseinrichtung mit einem Innenkanal des Zylinderkörpers / der Druckhülse in Verbindung stehen, wenn das Verbindungselement an dem Zylinderkörper / der Druckhülse angeordnet ist.One or more internal channels can be formed in the cylinder body of the printing plate cylinder and/or the printing sleeve, which are connected to the transmission device, at least when the transmission element is displaced into the extended position. In the retracted position, the connecting element of the transmission device can be connected to an internal channel of the cylinder body/the printing sleeve if the connecting element is arranged on the cylinder body/the printing sleeve.
Eine Spitze des Verbindungselements kann konisch oder hemisphärisch ausgebildet sein, alternativ beispielsweise auch zylindrisch oder rechteckig.A tip of the connecting element can be conical or hemispherical, alternatively for example cylindrical or rectangular.
Um Leckagen während der Überbrückung vom Druckplattenzylinder zur Druckhülse zu unterbinden, kann entweder mindestens ein Dichtungselement in der Druckhülse oder einem Druckadapter und / oder auf der Spitze des Verbindungselements angeordnet sein. Als Dichtungselement kann beispielsweise ein Nitrilkautschuk- oder ein Fluorkautschukelement verwendet werden. Das Material des runden Dichtungselements kann eine Shore-A-Härte von etwa 70 aufweisen. Das Material Fluorkautschuk ist gegen Hitze, Öl, Alterung, Abrieb, Ozon, Kraftstoff und gegen aggressive Chemikalien beständig. Zudem bietet das Dichtungselement eine starke Abdichtung und gute Luftdichtigkeit für eine Vielzahl von Anwendungen wie Sanitär-, Maschinen-, Hydraulik- und Pneumatikanwendungen. Alternativ können ebenso speziell additiv gefertigte Dichtungselemente (mittels 3D-Druck) ihren Einsatz finden.In order to prevent leaks during the bridging from the printing plate cylinder to the printing sleeve, at least one sealing element can be arranged in the printing sleeve or a printing adapter and/or on the tip of the connecting element. A nitrile rubber or a fluororubber element can be used as a sealing element, for example. The material of the round sealing element can have a Shore A hardness of around 70. The fluororubber material is resistant to heat, oil, aging, abrasion, ozone, fuel and resistant to aggressive chemicals. In addition, the sealing element offers a strong seal and good airtightness for a wide range of applications such as sanitary, mechanical, hydraulic and pneumatic applications. Alternatively, specially additively manufactured sealing elements (using 3D printing) can also be used.
Im Falle einer Übertragung von elektrischer Energie und / oder Signalen kann mindestens eine Verbindungs- oder Versorgungseinrichtung innerhalb eines Druckplattenzylinders vorgesehen sein, um beide Polaritäten (plus, minus) bereitzustellen. Hierbei kann ein Grundkörper der Verbindungs- oder Versorgungselemente elektrisch isolierend sein, und im Inneren kann ein elektrisch leitender Zylinderstift angeordnet sein.In the case of a transmission of electrical energy and/or signals, at least one connection or supply device can be provided within a printing plate cylinder in order to provide both polarities (plus, minus). In this case, a base body of the connection or supply elements can be electrically insulating, and an electrically conductive cylinder pin can be arranged inside.
In jeweiligen Luftkanälen von Druckplattenzylinder und Druckhülse können elektrisch isolierte Leiter verlegt sein, die schließlich mit dem elektrisch leitenden Zylinderstift innerhalb des Verbindungselements verbunden sind.Electrically insulated conductors can be laid in the respective air channels of the printing plate cylinder and printing sleeve, which are finally connected to the electrically conductive cylinder pin within the connecting element.
Eine Aufnahme an der Druckhülse kann aus einer elektrisch isolierenden Hülse samt eines innen angeordneten, elektrisch leitenden Zylinderstiftes sein, der wiederum jeweils mit einem elektrisch isolierten Leiter verbunden ist. Somit kann gewährleistet werden, dass keine Stromspannung im direkten Kontakt mit dem Druckplattenzylinder als auch in der Druckhülse anliegt.A mount on the printing sleeve can consist of an electrically insulating sleeve with an electrically conductive cylinder pin arranged inside, which in turn is connected to an electrically insulated conductor. This ensures that no voltage is present in direct contact with the printing plate cylinder or in the printing sleeve.
Alternativ können eine Aufnahme oder ein Gegenstück als auch das Verbindungselement für eine elektrische Versorgung sowie für eine Signal-Versorgung und zugleich für die Weiterleitung von Druckluft ausgestaltet werden.Alternatively, a receptacle or a counterpart as well as the connecting element can be designed for an electrical supply as well as for a signal supply and at the same time for the transmission of compressed air.
Mit einer solchen elektrischen und / oder einer Signal-Versorgungsvorrichtung können Sensoren, Messinstrumente, Datenverarbeitungsanlagen sowie Aktuatoren innerhalb eines Druckadapters / einer Druckhülse mit Strom versorgt und Daten an die Rotationsdruckmaschine übertragen werden. Dies ermöglicht neue Einsatzfelder solcher Produkte innerhalb einer Rotationsdruckmaschine, zum Beispiel zum Sammeln von Daten, insbesondere Betriebsdaten, und / oder für "Predictive Analytics".With such an electrical and/or signal supply device, sensors, measuring instruments, data processing systems and actuators within a printing adapter/printing sleeve can be supplied with power and data can be transmitted to the rotary printing press. This enables new fields of application for such products within a rotary printing press, for example for collecting data, in particular operating data, and/or for "predictive analytics".
In Verbindung mit dem Verfahren zum Herstellen der Anordnung für eine Druckmaschine mit dem Druckplattenzylinder können die vorangehend im Zusammenhang mit dem Druckplattenzylinder erläuterten Ausgestaltungen entsprechend vorgesehen sein.In connection with the method for producing the arrangement for a printing press with the printing plate cylinder, the embodiments explained above in connection with the printing plate cylinder can be provided accordingly.
