Description

Die Erfindung bezieht sich auf eine Vorrichtung zur Identifizierung eines Walzenmantels, der aus flexiblem Material gefertigt ist und in Druckmaschinen zum Einsatz kommt.The invention relates to a device for identifying a roll shell, which is made of flexible material and is used in printing presses.

Insbesondere in Großdruckereien stellt die überwachung des Lagerstandes von Gummitüchern bzw. Gummiwalzen ein Problem dar. Zwar tragen die Gummitücher bzw. die Gummiwalzen üblicherweise eingeprägte Identifikationsmerkmale; infolge von Abnutzung werden diese Identifikationsmerkmale jedoch unleserlich, sobald die Gummitücher oder Gummiwalzen bereits bei einem Druckprozeß eingesetzt waren. Da sich die Wahl des Gummituchs bzw. der Gummiwalze nach den jeweiligen Druckparametern, beispielsweise der Farbe, richtet, muß sichergestellt sein, daß die Auswahl des Gummituchs bzw. der Gummiwalze stets eindeutig möglich ist.In large printing plants in particular, monitoring the stock level of rubber blankets or rubber rollers is a problem. The rubber blankets or rubber rollers usually have stamped identification features; As a result of wear and tear, these identification features become illegible as soon as the rubber blankets or rubber rollers have already been used in a printing process. Since the choice of the rubber blanket or the rubber roller depends on the respective printing parameters, for example the color, it must be ensured that the selection of the rubber blanket or the rubber roller is always clearly possible.

Die NL 87 02 416 beschreibt eine Vorrichtung zum Handhaben von Rotations-Siebdruckschablonen, die einen oder mehrere mit einer zentralen Steuereinheit gekoppelte Abtaster aufweist, die eine auf den Schablonen in Form eines Mikrochips vorliegende Information erkennen.NL 87 02 416 describes a device for handling rotary screen printing stencils which has one or more scanners coupled to a central control unit which recognize information present on the stencils in the form of a microchip.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zu schaffen, die eine Identifizierung eines Walzenmantels eindeutig ermöglicht.The invention has for its object to provide a device that clearly identifies a roll shell.

Die Aufgabe wird erfindungsgemäß durch die Merkmale von Anspruch 1 gelöst.The object is achieved by the features of claim 1.

Gemäß einer Weiterbildung der erfindungsgemäßen Vorrichtung ist vorgesehen, daß der Mikrochip in ein Gummituch eingearbeitet ist, das auf den Gummituchzylinder einer Druckmaschine aufgespannt wird. Durch die eindeutigen Identifizierungsmerkmale des Mikrochips läßt sich der Lagerbestand an Gummitüchern bzw. an Gummiwalzen problemlos überwachen. Darüber hinaus lassen sich Aussagen über die Lebensdauer von Gummitüchern bzw. Gummiwalzen machen, insbesondere dann, wenn diese Gummitücher zu mehreren Einsätzen an evtl. noch verschiedenen Druckmaschinen kommen. Außerdem läßt sich anhand der eindeutigen Identifikationsmerkmale der optimale Einsatzbereich der Gummitücher bzw. der Gummiwalzen in Abhängigkeit von verschiedenen Druckparametern bestimmen.According to a development of the device according to the invention it is provided that the microchip is in a rubber blanket is incorporated, which is clamped on the blanket cylinder of a printing press. Due to the unique identification features of the microchip, the inventory of blankets or rubber rollers can be easily monitored. In addition, statements can be made about the service life of rubber blankets or rubber rollers, especially if these rubber blankets are used several times on possibly different printing presses. In addition, based on the unique identification features, the optimal area of application of the rubber blankets or the rubber rollers can be determined as a function of various printing parameters.

Gemäß einer Weiterbildung der erfindungsgemäßen Vorrichtung ist vorgesehen, daß die entsprechenden Daten - beispielsweise die Lebensdauer des Gummituchs bzw. der Gummiwalze oder ihre Tauglichkeit für einen Einsatz im Zusammenhang mit gewissen Druckfarben - in einer Speichereinrichtung abgespeichert werden. Durch die Abtasteinrichtung werden Signale ausgelöst, die eine eindeutige Identifizierung des Mikrochips erlauben. Es wird z. B. jedem Mikrochip eine Identifikationsnummer zugeordnet, die auf einer der Speichereinrichtung zugeordneten Anzeigeeinrichtung abzulesen ist. Unter dieser Nummer kann zusätzliche Information über das Gummituch oder die Gummiwalze in der Speichereinrichtung abgespeichert werden. Diese Information ist jederzeit abrufbar.According to a development of the device according to the invention, it is provided that the corresponding data - for example the service life of the rubber blanket or the rubber roller or its suitability for use in connection with certain printing inks - are stored in a storage device. The scanning device triggers signals which allow the microchip to be clearly identified. It is e.g. B. assigned to each microchip an identification number that can be read on a display device assigned to the memory device. Additional information about the rubber blanket or the rubber roller can be stored under this number in the storage device. This information is available at any time.

Eine spezielle Ausführungsform der erfindungsgemäßen Vorrichtung sieht vor, daß es sich bei den Signalen, die der Mikrochip aussendet, um Radiowellen handelt. Diese Radiowellen sind derart moduliert, daß sie in eindeutiger Weise die Information über die jeweilige Identifikationsnummer tragen.A special embodiment of the device according to the invention provides that the signals which the microchip emits are radio waves. These radio waves are modulated in such a way that they uniquely carry the information about the respective identification number.

Die Erfindung wird in der folgenden Beschreibung eines bevorzugten Ausführungsbeispiels anhand der beigefügten Zeichnung näher erläutert.

Fig. 1
ist eine schematische Darstellung der erfindungsgemäßen Vorrichtung in Kombination mit einer schematischen Schaltanordnung
The invention is explained in more detail in the following description of a preferred embodiment with reference to the accompanying drawing.
Fig. 1
is a schematic representation of the device according to the invention in combination with a schematic switching arrangement

Fig. 1 gezeigte erfindungsgemäße Vorrichtung besteht aus einem Mikrochip 3 und einer Abtasteinrichtung 4. In den Walzenmantel 2 einer Walze 1 ist ein Mikrochip 3 eingearbeitet. Bei der Walze 1 handelt es sich um eine Gummiwalze, wie sie beispielsweise in dem nicht dargestellten Farbwerk einer nicht dargestellten Druckmaschine angeordnet ist. Eine weitere Möglichkeit sieht vor, daß es sich bei dem Walzenmantel 2 um ein Gummituch handelt. Dieses Gummituch wird in einer Offsetdruckmaschine auf den Gummituchzylinder aufgespannt und dient der übertragung des Druckbildes von dem Plattenzylinder zu dem Bedruckstoff.1 consists of a microchip 3 and a scanning device 4. In the roll shell 2 of a roll 1, a microchip 3 is incorporated. The roller 1 is a rubber roller, as is arranged, for example, in the inking unit, not shown, of a printing machine, not shown. Another possibility provides that the roller jacket 2 is a rubber blanket. This blanket is clamped onto the blanket cylinder in an offset printing machine and is used to transfer the print image from the plate cylinder to the printing material.

Insbesondere bei der Anordnung des Mikrochips 3 in einem Gummituch ist vorgesehen, daß die Abmessungen dieses Mikrochips 3 in der Größenordnung von mm2 liegen. Durch diese geringe Größe des Mikrochips 3 bleibt die Oberflächenbeschaffenheit des Gummituchs weitgehend unberührt.In particular when the microchip 3 is arranged in a rubber blanket, it is provided that the dimensions of this microchip 3 are of the order of mm 2 . Due to this small size of the microchip 3, the surface condition of the rubber blanket remains largely unaffected.

Der Mikrochip 3 sendet charakteristische Signale aus, die eine eindeutige Identifizierung des Mikrochips 3 und damit des Gummituchs bzw. der Gummiwalze erlauben, wenn er von Signalen der Abtasteinrichtung 4 erregt wird. Vorteilhafterweise liegen diese Signale im Radiobereich, wodurch eine Identifizierung auch über größere Entfernungen störungsfrei möglich wird.The microchip 3 sends out characteristic signals which allow the microchip 3 and thus the rubber blanket or the rubber roller to be clearly identified when it is excited by signals from the scanning device 4. These signals are advantageously in the radio range, which means that identification is possible without interference even over long distances.

Die Abtasteinrichtung 4 kann derart ausgebildet sein, daß sie direkt mit einem Rechner 5 verbunden ist. Diesem Rechner 5 ist eine Speichereinrichtung 6 zugeordnet, in der wichtige Informationen über die einzelnen Gummitücher oder Gummiwalzen enthalten sind. Diese Informationen sind in Abhängigkeit von der jeweiligen Identifikationsnummer, die aus den Signalen des Mikrochips erhalten wird, abgespeichert und können vom Drucker jederzeit abgerufen werden. Eventuelle Korrekturen oder Ergänzungen des Informationsgehaltes sind problemlos möglich.The scanning device 4 can be designed such that it is connected directly to a computer 5. A memory device 6 is assigned to this computer 5 and contains important information about the individual rubber blankets or rubber rollers. This information is stored depending on the respective identification number, which is obtained from the signals of the microchip, and can be called up by the printer at any time. Any corrections or additions to the information content are possible without any problems.
