Description

Die Erfindung betrifft eine Vorrichtung zum flächenhaften Auftragen von streichfähigen Medien, wie Leim, Lack etc., auf ein vorzugsweise bahnförmiges Trägermaterial, insbesondere eine bedruckte Papierbahn, mit zwei einen Arbeitsspalt, durch den das Trägermaterial hindurchführbar ist, begrenzenden Arbeitszylindern, von denen wenigstens einer als aus einem Kern mit umfangsseitiger Auflage bestehender Übertragungszylinder ausgebildet ist, dem eine Versorgungseinrichtung zugeordnet ist, die vorzugsweise wenigstens eine zur Anlage am zugeordneten Übertragungszylinder bringbare Auftragwalze enthält.The invention relates to a device for the extensive application of spreadable media, such as glue, varnish, etc., on a preferably web-shaped carrier material, in particular a printed paper web, with two working cylinders delimiting a working gap through which the carrier material can be passed, of which at least one is used as a is formed from a core with a peripheral support existing transfer cylinder, to which a supply device is assigned, which preferably contains at least one applicator roll which can be brought into contact with the assigned transfer cylinder.

Leimvorrichtungen eingangs erwähnter Art sind bekannt (siehe z.B. US-A-4 574 732). Diese finden in der Regel im Rahmen von sogenannten Inline-Produktionsstraßen Verwendung. Diese bekannten Anordnungen bestehen aus einem stationären Gestell, auf dem die Arbeitszylinder und die zugeordneten Versorgungseinrichtungen aufgenommen sind. Es ist daher praktisch nicht möglich, die Arbeitszylinder auszutauschen. Beim Auftragen von Leim wird eine vergleichsweise weiche Umfangsfläche der Übertragungszylinder benötigt. Hierzu finden vergleichsweise dicke, auf einen Metallkern aufgeklebte Schaumstoffklischees Verwendung, die entsprechend dem gewünschten Druckbild zugeschnitten sind. Demgegenüber wird beim Auftragen von Lack mit einer durch ein Gummituch gebildeten Umfangsfläche gearbeitet.Glue devices of the type mentioned at the outset are known (see, for example, US Pat. No. 4,574,732). These are usually found on so-called inline production lines Use. These known arrangements consist of a stationary frame on which the working cylinders and the associated supply devices are accommodated. It is therefore practically not possible to replace the working cylinders. When applying glue, a comparatively soft peripheral surface of the transfer cylinder is required. For this purpose, comparatively thick foam clichés glued to a metal core are used, which are cut according to the desired print image. In contrast, when applying lacquer, a circumferential surface formed by a rubber blanket is used.

Sofern nun versucht wird, was in der Praxis nicht selten vorkommt, die bekannten Leimvorrichtungen zum Auftragen von Lack zu benutzen, muß auf den vergleichsweise dünnen Metallkern ein vergleichsweise dicker Bezug aufgebracht werden. In diesem Zusammenhang ist nämlich davon auszugehen, daß in jedem Falle ein dem Arbeitsdurchmesser der Druckwerkszylinder einer vorgeordneten Druckmaschine entsprechender Arbeitsdurchmesser der Arbeitszylinder der Leim- bzw. Lackiervorrichtung erreicht werden muß. Bisher muß daher das beim Lackieren Verwendung findende, vergleichsweise dünne Gummituch mit Auffütterungsmaterial unterlegt werden. Dies führt jedoch zu einem vergleichsweise dicken und dementsprechend sehr elastischen Gesamtbezug, was beim Auftragen von Lack ungünstig ist. Zudem besteht die Gefahr, daß ein derartiger, mehrlagiger Bezug auch nicht die erforderliche Haltbarkeit aufweist. Abgesehen davon ergibt die Verwendung eines mehrlagigen Bezugs auch einen nicht unerheblichen Aufwand.If an attempt is now made, which is not uncommon in practice, to use the known glue devices for applying lacquer, a comparatively thick cover must be applied to the comparatively thin metal core. In this context, it can be assumed that in any case the working diameter of the gluing or coating device must correspond to the working diameter of the printing unit cylinders of an upstream printing press. So far, therefore, the comparatively thin rubber blanket used in painting has to be underlaid with padding material. However, this leads to a comparatively thick and accordingly very elastic overall cover, which is disadvantageous when applying lacquer. There is also the risk that such a multi-layer cover does not have the required durability. Apart from that, the use of a multi-layer cover also results in a not inconsiderable effort.

Hiervon ausgehend ist es daher die Aufgabe der vorliegenden Erfindung, eine Vorrichtung eingangs erwähnter Art mit einfachen und kostengünstigen Mitteln unter Vermeidung der Nachteile der bekannten Anordnungen so zu verbessern, daß ein schneller Wechsel von einer Betriebsart zu einer anderen möglich ist und daß dennoch in jedem Falle optimale Arbeitsbedingungen erreicht werden können.Proceeding from this, it is therefore the object of the present invention to improve a device of the type mentioned at the outset with simple and inexpensive means, while avoiding the disadvantages of the known arrangements, in such a way that a quick change from one operating mode to another is possible and yet in any case optimal working conditions can be achieved.

Diese Aufgabe wird erfindungsgemäß gelöst durch ein wenigstens eine Auftrageinrichtung und eine Aufnahmeeinrichtung für eine Kassette aufweisendes, stationäres Grundgestell, an dem jeweils eine mit zwei Arbeitszylindern versehene Wechselkassette fixierbar ist.This object is achieved according to the invention by a stationary base frame having at least one application device and a receiving device for a cassette, on each of which an exchangeable cassette provided with two working cylinders can be fixed.

Mit diesen Maßnahmen lassen sich die eingangs geschilderten Nachteile vollständig beseitigen. Die erfindungsgemäßen Maßnahmen bieten die Möglichkeit eines schnellen und einfachen Zylinderwechsels, so daß die erfindungsgemäße Vorrichtung schnell und einfach z.B. von Leimauftrag auf Lackauftrag umgerüstet werden kann und umgekehrt, wobei der Kerndurchmesser des Übertragungszylinders bzw. der Übertragungszylinder in jedem Falle den speziellen Bedürfnissen des Einzelfalls angepaßt sein kann. Die für Leimauftrag vorgesehene Kassette bzw. Kassetten kann bzw. können dementsprechend mit jeweils wenigstens einem Übertragungszylinder versehen sein, dessen Kerndurchmesser kleiner ist als der Kerndurchmesser des bzw. der Übertragungszylinder einer für Lackauftrag vorgesehenen Kassette. Eine Unterfütterung ist daher in vorteilhafter Weise nicht notwendig, was sich nicht nur vorteilhaft auf die erzielbare Oberflächenhärte, sondern auch auf die Zylinderhaltbarkeit auswirkt. Ein weiterer Vorteil der erfindungsgemäßen Maßnahmen ist darin zu sehen, daß durch Abnahme der Kassetten ein geräumiger Bypass für das Trägermaterial geschaffen werden kann, sofern die erfindungsgemäße Vorrichtung außer Betrieb sein soll. Es ist daher in vorteilhafter Weise nicht erforderlich, durch Verschwenken der Arbeitszylinder einen derartigen Bypass zu schaffen. Vielmehr ist lediglich die Wechselkassette abzunehmen. Außerdem ist vorteilhaft, daß die kassettenseitigen Arbeitszylinder bei abgenommener Kassette gut zugänglich sind, was die Reinigung, Wartung und Instandhaltung erleichtert. Die erfindungsgemäßen Maßnahmen ermöglichen zudem in vorteilhafter Weise auch eine Erweiterung einer zunächst vorhandenen Grundausrüstung Zug um Zug, indem einfach weitere Wechselkassetten angeschafft bzw. das Grundgestell mit einem Aufsatz versehen werden. Die erfindungsgemäßen Maßnahmen gewährleisten somit in vorteilhafter Weise eine hohe Vielseitigkeit und ergeben damit insgesamt eine ausgezeichnete Wirtschaftlichkeit.With these measures, the disadvantages described above can be completely eliminated. The measures according to the invention offer the possibility of a quick and easy cylinder change, so that the device according to the invention can be converted quickly and easily, for example from glue application to lacquer application and vice versa, the core diameter of the transfer cylinder or the transfer cylinder being adapted in each case to the special needs of the individual case can. Accordingly, the cassette or cassettes intended for glue application can be provided with at least one transfer cylinder, the core diameter of which is smaller than the core diameter of the transfer cylinder or cylinders of a cassette intended for coating application. Relining is therefore advantageously not necessary, which is what not only has an advantageous effect on the surface hardness that can be achieved, but also on cylinder durability. Another advantage of the measures according to the invention can be seen in the fact that by removing the cassettes a spacious bypass can be created for the carrier material if the device according to the invention is to be out of operation. It is therefore advantageously not necessary to create such a bypass by pivoting the working cylinders. Rather, only the removable cassette has to be removed. It is also advantageous that the cartridge-side working cylinders are easily accessible when the cartridge is removed, which facilitates cleaning, maintenance and repair. The measures according to the invention also advantageously make it possible to expand existing basic equipment step by step by simply purchasing additional exchangeable cassettes or by providing the base frame with an attachment. The measures according to the invention thus advantageously ensure a high degree of versatility and thus result in excellent overall economy.

Vorteilhafte Ausgestaltungen und zweckmäßige Fortbildungen der übergeordneten Maßnahmen sind in den Unteransprüchen angegeben.Advantageous refinements and appropriate further training of the higher-level measures are specified in the subclaims.

Der Aufbau von Druckmaschinen, wie Rollenrotationsdruckmaschinen, ist an sich bekannt und bedarf daher im vorliegenden Fall keiner näheren Erläuterung mehr. Dasselbe gilt für an solche Druckmaschinen sich anschließende Inline-Produktionsstraßen. Im Rahmen einer derartigen Produktionsstraße soll nach dem letzten Druckwerk und vor dem Trockner die der Zeichnung zugrundeliegende, kombinierte Leim- und Lackiervorrichtung angeordnet sein, mit welcher Dispersionsleim bzw. Dispersionslack verarbeitet, das heißt auf die in der vorgeordneten Druckmaschine bedruckte Papierbahn aufgetragen werden kann.The construction of printing presses, such as web-fed rotary printing presses, is known per se and therefore does not require any further explanation in the present case. The same applies to inline production lines connected to such printing machines. In the context of such a production line, the combined glue and varnishing device on which the drawing is based should be arranged after the last printing unit and before the dryer, with which dispersion glue or dispersion varnish is processed, that is to say it can be applied to the paper web printed in the upstream printing press.

Hierzu sind zwei Arbeitszylinder 1, 2 vorgesehen, zwischen denen die Papierbahn 3 hindurchgeführt wird. Der Arbeitsdurchmesser der Arbeitszylinder 1, 2 entspricht dem Arbeitsdurchmesser der Druckwerkszylinder der vorgeordneten Druckmaschine, wodurch einem sogenannten Doublieren vorgebeugt werden soll. Bei der der Figur 1 zugrundeliegenden Anordnung fungieren der untere Arbeitszylinder 1 als Übertragungszylinder und der obere Arbeitszylinder 2 als Gegenhaltezylinder. Dieser besitzt hier eine harte Metalloberfläche. Bei Verwendung von Chrom ergibt sich eine farbabstoßende Wirkung, wodurch einem Abschmieren des frischen Drucks auf der Papierbahn 3 vorgebeugt werden kann. Zusätzlich kann der als Gegenhaltezylinder fungierende Arbeitszylinder 2 hierzu mit einem farbabstoßenden Feuchtmittelfilm versehen werden, was weiter unten noch näher ausgeführt werden wird. Der als Übertragungszylinder fungierende Arbeitszylinder 1 besteht aus einem Metallkern 4, auf den eine demgegenüber weiche Umfangsauflage 5 aufgebracht ist.For this purpose, two working cylinders 1, 2 are provided, between which the paper web 3 is passed. The working diameter of the working cylinders 1, 2 corresponds to the working diameter of the printing unit cylinders of the upstream printing press, which is intended to prevent so-called duplication. 1 underlying arrangement, the lower cylinder 1 function as a transfer cylinder and the upper cylinder 2 as a counter cylinder. This has a hard metal surface here. When chromium is used, there is an ink-repelling effect, as a result of which the fresh print on the paper web 3 can be prevented from smearing. In addition, the working cylinder 2 acting as a counter-cylinder can be provided with an ink-repellent dampening film, which will be explained in more detail below. The working cylinder 1, which acts as a transfer cylinder, consists of a metal core 4, onto which a circumferential support 5, which is in contrast soft, is applied.

Der als Übertragungszylinder fungierende Arbeitszylinder 1 wird durch eine zugeordnete Versorgungseinrichtung 6 mit Leim bzw. Lack versorgt. Die Versorgungseinrichtung 6 besteht hier aus einer am Übertragungszylinder anliegenden Auftragwalze 7, die mit einer in eine Wanne 8 eintauchenden Tauchwalze 9 und einer Dosierwalze 10 zusammenwirkt. Die Auftragwalze 7 und die Tauchwalze 9 wirken hier mit ihre Stirnseiten abrakelnden Seitenrakeln 11 zusammen. Die Vorratswanne 8 wird je nach Betriebsart mit Leim oder Lack beschickt. Dies kann im Durchlaufverfahren geschehen. Zusätzlich kann die Vorratswanne 8 mit einer Konditioniereinrichtung zum Kühlen oder Heizen des jeweiligen Mediums versehen sein.The working cylinder 1, which acts as a transfer cylinder, is supplied with glue or varnish by an assigned supply device 6. The supply device 6 here consists of an application roller 7 which bears against the transfer cylinder and which interacts with an immersion roller 9 which dips into a tub 8 and a metering roller 10. The application roller 7 and the dipping roller 9 cooperate here with the side doctor blades 11 which are doctoring off their end faces. The storage tub 8 is loaded with glue or varnish depending on the operating mode. This can be done in a continuous process. In addition, the storage trough 8 can be provided with a conditioning device for cooling or heating the respective medium.

Bei der den Figuren 1 und 3 zugrundeliegenden Ausführung sind jeweils zwei übereinander angeordnete Versorgungseinrichtungen 6 vorgesehen. Diese sind auf einem stationären Grundgestell 12 aufgenommen. Es wäre denkbar, das Grundgestell 12 zweiteilig zu gestalten, das heißt so auszubilden, daß es zunächst lediglich die untere Versorgungseinrichtung 6 enthält und durch einen die obere Versorgungseinrichtung 6 aufnehmenden Aufsatz erweitert werden kann, wie durch die Trennfuge 13 angedeutet ist. Die Arbeitszylinder 1, 2 sind auf einer Wechselkassette 14 aufgenommen, die wahlweise auf dem Grundgestell 12 aufnehmbar ist. Das Grundgestell 12 ist hierzu mit einer entsprechenden Aufnahmeeinrichtung, hier in Form einer Wandausnehmung 15 versehen, in welche die Wechselkassette mit einem entsprechenden Vorsprung einschiebbar ist. Zur Justierung und Fixierung können Bolzen und/oder Schrauben vorgesehen sein, wie bei 16 angedeutet ist.In the embodiment on which FIGS. 1 and 3 are based, two supply devices 6 arranged one above the other are provided. These are on one stationary base frame 12 added. It would be conceivable to design the base frame 12 in two parts, that is, to design it in such a way that it initially only contains the lower supply device 6 and can be expanded by an attachment which accommodates the upper supply device 6, as indicated by the parting line 13. The working cylinders 1, 2 are accommodated on an exchangeable cassette 14 which can optionally be accommodated on the base frame 12. For this purpose, the base frame 12 is provided with a corresponding receiving device, here in the form of a wall recess 15, into which the exchangeable cassette can be inserted with a corresponding projection. Bolts and / or screws can be provided for adjustment and fixation, as indicated at 16.

Die am Grundgestell 12 lösbar festlegbare Wechselkassette 14 ist abnehmbar und durch eine andere Wechselkassette ersetzbar, deren Arbeitszylinder für eine andere Betriebsart eingerichtet sind. Dementsprechend können einem Grundgestell 12 mehrere Wechselkassetten 14 der in Figur 2 angedeuteten Art zugeordnet sein. Jede Wechselkassette 14 besteht aus einem Kassettengestell 17, auf dem die zugeordneten Arbeitszylinder 1, 2 aufgenommen sind. Die Kassettengestelle 17 aller Wechselkassetten 14 sind gleich und so konfiguriert, daß sie auf die zugeordnete Aufnahmeeinrichtung 15 des Grundgestells 12 passen. Die Anordnung und Ausbildung der Arbeitszylinder 1, 2 der verschiednenen Wechselkassetten 14 ist unterschiedlich, um unterschiedliche Betriebsarten bewerkstelligen zu können.The exchangeable cassette 14, which can be detachably fixed on the base frame 12, is removable and can be replaced by another exchangeable cassette, the working cylinders of which are set up for a different operating mode. Accordingly, a plurality of interchangeable cassettes 14 of the type indicated in FIG. 2 can be assigned to a base frame 12. Each exchangeable cassette 14 consists of a cassette frame 17 on which the associated working cylinders 1, 2 are accommodated. The cassette frames 17 of all interchangeable cassettes 14 are the same and configured so that they fit on the associated receiving device 15 of the base frame 12. The arrangement and design of the working cylinders 1, 2 of the different exchangeable cassettes 14 are different in order to be able to accomplish different operating modes.

Die Arbeitszylinder 1, 2 der in Figur 1 am Grundgestell 12 fixierten Wechselkassette 14 sind so angeordnet, daß nur der untere Arbeitszylinder 1, der hier als Übertragungszylinder fungiert, in Kontakt mit der Auftragwalze 7 der benachbarten, unteren Versorgungseinrichtung 6 kommt. Zwischen dem oberen, als Gegenhaltezylinder fungierenden Arbeitszylinder 2 und der benachbarten Auftragwalze der oberen Versorgungseinrichtung 6 ergibt sich ein Spalt. Der als Übertragungszylinder fungierende, untere Arbeitszylinder 1 ist hier so ausgebildet, daß Leim auf die Papierbahn 2 aufgetragen werden kann. Hierzu ist der Durchmesser des Kerns 4 so dimensioniert, daß auf ihm weiche, vergleichsweise dicke Schaumstoffklischees zur Bildung des Umfangsbezugs 5 aufgenommen werden können. Die Dicke dieser Schaumstoffklischees beträgt 3 bis 4 mm. Diese werden entsprechend dem gewünschten Leimauftragbild zugeschnitten und auf den Kern 4 mittels selbstklebender Folien aufgeklebt. Die Wanne 8 der hier aktivierten, unteren Versorgungseinrichtung 6 wird bei der der Figur 1 zugrundeliegenden Betriebsart mit Leim beaufschlagt. Die obere Versorgungseinrichtung 6 ist stillgelegt.The working cylinders 1, 2 of the interchangeable cassette 14 fixed to the base frame 12 in FIG. 1 are arranged such that only the lower working cylinder 1, which functions here as a transfer cylinder, comes into contact with the application roller 7 of the adjacent, lower supply device 6. There is a gap between the upper working cylinder 2, which acts as a counter-holding cylinder, and the adjacent applicator roller of the upper supply device 6. The lower working cylinder 1, which acts as a transfer cylinder, is designed here so that glue can be applied to the paper web 2. For this purpose, the diameter of the core 4 is dimensioned such that soft, comparatively thick foam clichés can be accommodated on it to form the peripheral cover 5. The thickness of these foam blocks is 3 to 4 mm. These are cut according to the desired glue application image and glued to the core 4 by means of self-adhesive films. The tub 8 of the lower supply device 6 activated here is supplied with glue in the operating mode on which FIG. 1 is based. The upper supply device 6 is shut down.

Die der Figur 2 zugrundeliegende Wechselkassette dient zum Auftragen von Leim auf die Oberseite der Papierbahn 3. Dementsprechend befindet sich hier der als Übertragungszylinder fungierende Arbeitszylinder 1 oberhalb des als Gegenhaltezylinder fungierenden Arbeitszylinders 2. Der hier obere Arbeitszylinder 1 ist dabei so angeordnet, daß er beim Einsetzen der Wechselkassette 14 in das Grundgestell 12 in Kontakt mit der benachbarten Auftragwalze der oberen Versorgungseinrichtung 6 kommt, die in diesem Fall aktiviert wird. Ansonsten kann der Aufbau der Arbeitszylinder 1, 2 der Figur 2 der Anordnung gemäß Figur 1 entsprechen.The interchangeable cassette on which FIG. 2 is based is used to apply glue to the top of the paper web 3. Accordingly, the working cylinder 1, which acts as a transfer cylinder, is located above the working cylinder 2, which acts as a counter-holding cylinder. The upper working cylinder 1 is arranged such that it is inserted the exchangeable cassette 14 into the base frame 12 in contact with the neighboring one Application roller of the upper supply device 6 comes, which is activated in this case. Otherwise, the construction of the working cylinders 1, 2 of FIG. 2 can correspond to the arrangement according to FIG. 1.

Soll nun die der Figur 1 zugrundeliegende Vorrichtung von Leimauftrag auf die Bahnunterseite auf Leimauftrag auf die Bahnoberseite umgestellt werden, wird einfach die in Figur 1 am Grundgestell 12 fixierte Wechselkassette 14 entfernt und durch die der Figur 2 zugrundeliegende Wechselkassette 14 ersetzt. Gleichzeitig werden die obere Versorgungseinrichtung 6 aktiviert und die untere Versorgungseinrichtung 6 passiviert.If the device on which FIG. 1 is based is now to be switched from glue application on the underside of the web to glue application on the top of the web, the exchangeable cassette 14 fixed to the base frame 12 in FIG. 1 is simply removed and replaced by the exchangeable cassette 14 on which FIG. 2 is based. At the same time, the upper supply device 6 is activated and the lower supply device 6 is passivated.

Bei dem der Figur 3 zugrundeliegenden Beispiel befindet sich eine weitere Wechselkassette 14 im Einsatz, die für ganzflächige Lackierung der Bahn 3 von oben und unten eingerichtet ist. Ansonsten entspricht der Aufbau der Anordnung gemäß Figur 1. Für gleiche Teile finden daher gleiche Bezugszeichen Verwendung. Bei dem der Figur 3 zugrundeliegenden Beispiel kommt jeder Arbeitszylinder 1, 2 der am Grundgestell 12 fixierten Wechselkassette 14 zur Anlage an der jeweils benachbarten Auftragwalze 7. Beide Arbeitszylinder 1, 2 fungieren hier als Übertragungszylinder und gleichzeitg als dem jeweils gegenüberliegenden Arbeitszylinder zugeordneter Gegenhaltezylinder. Die für Lackauftrag ausgebildeten Arbeitszylinder 1, 2 bestehen wiederum aus einem Kern 4 mit hierauf aufgenommener Umfangsauflage 5. Diese wird hier durch einen Gummibezug mit einer Dicke von etwa 1,5 mm bis 2 mm gebildet. Hierzu kann auf den Kern 5 ein Gummibezug aufvulkanisiert oder ein Gummituch aufgespannt sein. Der Durchmesser des Kerns 4 ist hierbei entsprechend der geringeren Dicke des hier Verwendung findenden Umfangsbezugs 5 größer als der Kern von für Leimauftrag vorgesehenen Übertragungszylindern. Beide Versorgungseinrichtungen 6 werden hier mit Lack beaufschlagt.In the example on which FIG. 3 is based, a further interchangeable cassette 14 is used, which is set up for painting the entire surface of the web 3 from above and below. Otherwise, the structure corresponds to the arrangement according to FIG. 1. The same reference numerals are therefore used for the same parts. In the example on which FIG. 3 is based, each working cylinder 1, 2 of the exchangeable cassette 14 fixed to the base frame 12 comes to rest against the respectively adjacent applicator roller 7. Both working cylinders 1, 2 function here as transfer cylinders and simultaneously as counter-cylinders assigned to the respective opposite working cylinder. The working cylinders 1, 2 designed for paint application in turn consist of a core 4 with a peripheral support 5 accommodated thereon. This is formed here by a rubber cover with a thickness of approximately 1.5 mm to 2 mm. For this purpose, a rubber cover can be placed on the core 5 vulcanized or a rubber blanket. The diameter of the core 4 is in this case corresponding to the smaller thickness of the circumferential cover 5 used here than the core of transfer cylinders provided for glue application. Both supply devices 6 are applied with paint here.

Selbstverständlich wäre es auch denkbar, weitere Wechselkassetten 14, beispielsweise für einseitigen Lackauftrag vorzusehen. In einem derartigen Fall könnte der als Gegenhaltezylinder fungierende Arbeitszylinder wiederum mit einer Chromoberfläche versehen und so angeordnet sein, daß er nicht in Kontakt mit der jeweils benachbarten Auftragwalze kommt. Der als Übertragungszylinder fungierende Arbeitszylinder könnte den der Figur 3 zugrundeliegenden Aufbau aufweisen und so angeordnet sein, daß er mit der jeweils benachbarten Auftragwalze 7 in Kontakt kommt. Sofern die ganze, den Figuren 1 und 3 zugrundeliegende Arbeitseinheit stillgesetzt werden soll, wird die Wechselkassette 14 entfernt und die Bahn 3 einfach durch das dann kassettenfreie Grundgestell 12 hindurchgeführt.Of course, it would also be conceivable to provide further exchangeable cassettes 14, for example for one-sided coating. In such a case, the working cylinder functioning as a counter-cylinder could in turn be provided with a chrome surface and arranged so that it does not come into contact with the adjacent applicator roller. The working cylinder functioning as a transfer cylinder could have the structure on which FIG. 3 is based and be arranged such that it comes into contact with the adjacent applicator roller 7. If the entire work unit on which FIGS. 1 and 3 are based is to be stopped, the exchangeable cassette 14 is removed and the web 3 is simply passed through the then cassette-free base frame 12.

Die zwischen letzten Druckwerk und Trockner angeordnete Vorrichtung vorliegender Art kann vom Maschinenhauptantrieb der Druckmaschine aus angetrieben werden, wie in Figur 3 angedeutet ist. Hierzu kann zumindest eine auf dem Grundgestell 12 aufgenommene Walze mit einer über alle anzutreibenden Einheiten sich erstreckenden Längswelle 18 des Maschinenhauptantriebs antriebsmäßig verbunden sein. Im dargestellten Beispiel sind beide Auftragwalzen 7 mittels der Längswelle 8 antreibbar. Hierzu sind zu beiden Auftragwalzen 7 führende, mit jeweils einer Schaltkupplung 19 zum Zu- und Abschalten versehene Antriebsstränge 20 vorgesehen. Die Auftragwalzen 7 können mit seitlichen Stirnrädern versehen sein, von denen der Antrieb der kassettenseitigen Arbeitszylinder 1, 2 abgeleitet werden kann. Hierzu können diese ebenfalls mit seitlichen Stirnrädern versehen sein, wobei das seitliche Stirnrad des jeweils als Übertragungszylinder fungierenden Arbeitszylinders mit dem Stirnrad der zugeordneten Auftragwalze 7 in Eingriff kommt, wenn die betreffende Wechselkassette 14 in das Grundgestell 12 eingesetzt wird. Den Tauchwalzen 9 können Einzelantriebe mit steuerbaren Motoren zugeordnet sein, um die gewünschte Drehzahldifferenz einstellen zu können. Die Dosierwalzen 10 können antriebslos sein.The device of the present type arranged between the last printing unit and dryer can be driven by the main machine drive of the printing machine, as indicated in FIG. 3. For this purpose, at least one roller accommodated on the base frame 12 can be connected in terms of drive to a longitudinal shaft 18 of the machine main drive which extends over all units to be driven. In the example shown, both are application rollers 7 can be driven by means of the longitudinal shaft 8. For this purpose, drive trains 20 are provided leading to both application rollers 7, each provided with a clutch 19 for switching on and off. The application rollers 7 can be provided with lateral spur gears from which the drive of the cartridge cylinders 1, 2 on the cassette side can be derived. For this purpose, these can also be provided with lateral spur gears, the lateral spur gear of the working cylinder respectively functioning as the transfer cylinder coming into engagement with the spur gear of the assigned applicator roller 7 when the interchangeable cassette 14 in question is inserted into the base frame 12. The drives 9 can be assigned individual drives with controllable motors in order to be able to set the desired speed difference. The metering rollers 10 can be without a drive.

Die in Kontakt mit der Bahn 3 kommenden Arbeitszylinder 1, 2 können entsprechend der Druckan- bzw. Druckabstellung der Druckwerkszylinder der vorgeordneten Druckmaschine ebenfalls an- bzw. abgestellt werden. Hierzu können die Arbeitszylinder 1, 2, wie Figur 3 weiter erkennen läßt, in verstellbaren Exzenterbüchsen 21 gelagert sein, die mittels der Druckan- bzw. Druckabeinstelleinrichtung der Druckmaschine betätigbar sind. Eine weitergehende Schwenkbarkeit der Arbeitszylinder ist nicht erforderlich, da zur Bewerkstelligung eines geräumigen Bypasses bei stillgesetzter Vorrichtung einfach die Wechselkassette 14 abgenommen werden kann.The working cylinders 1, 2 coming into contact with the web 3 can also be switched on or off in accordance with the printing on or off of the printing unit cylinders of the upstream printing press. For this purpose, the working cylinders 1, 2, as can also be seen in FIG. 3, can be mounted in adjustable eccentric bushes 21, which can be actuated by means of the pressure adjusting or pressure adjusting device of the printing press. A further swiveling of the working cylinders is not necessary, since the exchangeable cassette 14 can simply be removed to accomplish a spacious bypass when the device is shut down.

In Fällen, in denen der eine Arbeitszylinder 2 als eine Metalloberfläche aufweisender Gegenhaltezylinder fungiert, wie bei den Beispielen gemäß Figur 1 und 2, wird dieser Arbeitszylinder 2, wie weiter oben schon angedeutet wurde, während des Betriebs laufend mit einem Feuchtmittelfilm prepariert. Hierzu sind die den Figuren 1 und 2 zugrundeliegenden Wechselkassetten 14 jeweils mit einer dem Arbeitszylinder 2 zugeordneten Befeuchtungseinrichtung 22 versehen, die jeweils aus einer Feuchtauftragwalze 23 und einer hiermit zusammenwirkenden, in eine Feuchtmittelwanne eintauchenden Tauchwalze 24 bestehen kann. Die Feuchtauftragwalze 23 kann dabei mit einem Strumpf aus Plüsch bezogen sein, so daß der zugeordnete Arbeitszylinder 2 gleichzeitig während des laufenden Betriebs permanent abgewischt und damit gereinigt wird. Die Feuchtauftragwalze 23 kann dementsprechend mit Relativdrehzahl gegenüber dem Arbeitszylinder 2 angetrieben werden. Als Feuchtmittel kann Wasser oder einfach das Offsetfeuchtmittel einer vorgeordneten Offsetdruckmaschine Verwendung finden. Da der Arbeitszylinder 2 hier einerseits mit einem farbabstoßenden Feuchtmittelfilm prepariert wird und andererseits permanent abgewischt wird, ist sichergestellt, daß die Umfangsfläche des Arbeitszylinders 2 über lange Betriebszeiten hinweg sauber gehalten werden kann. Bei dem der Figur 3 zugrundeliegenden Beispiel bei dem beide Arbeitszylinder 1, 2 als Übertragungszylinder fungieren, ist die Wechselkassette 14 ohne ein Feucht- und Wischwerk oben umrissener Art.In cases where the one cylinder 2 as one Counter cylinder which has a metal surface functions, as in the examples according to FIGS. 1 and 2, this cylinder 2, as already indicated above, is continuously prepared with a dampening solution film during operation. For this purpose, the exchangeable cassettes 14 on which FIGS. 1 and 2 are based are each provided with a moistening device 22 which is assigned to the working cylinder 2 and which can each consist of a dampening roller 23 and an immersing roller 24 which cooperates therewith and is immersed in a fountain solution pan. The dampening roller 23 can be covered with a stocking made of plush, so that the associated working cylinder 2 is simultaneously wiped and cleaned during operation. The dampening roller 23 can accordingly be driven at a relative speed with respect to the working cylinder 2. Water or simply the offset dampening solution of an upstream offset printing machine can be used as the dampening solution. Since the working cylinder 2 is prepared here on the one hand with an ink-repellent dampening film and on the other hand is permanently wiped, it is ensured that the peripheral surface of the working cylinder 2 can be kept clean over long operating times. In the example on which FIG. 3 is based, in which both working cylinders 1, 2 function as transfer cylinders, the exchangeable cassette 14 is of the type outlined above without a dampening and wiping mechanism.

Durch die vorstehende Beispielsbeschreibung wird der Schutzbereich der Ansprüche nicht beschränkt. Vielmehr stehen dem Fachmann eine Reihe von Möglichkeiten zur Verfügung, um den allgemeinen Gedanken der erfindungsgemäßen Lösung mit konstruktivem Gehalt zu erfüllen. So wäre es beispielsweise auch möglich, neben Wechselkassetten zur Verarbeitung von Leim und Lack auch weitere Wechselkassetten zur Verarbeitung von sogenannten Rubbel etc. vorzusehen.The scope of the claims is not restricted by the above description of examples. Much more A number of possibilities are available to the person skilled in the art to fulfill the general idea of the solution according to the invention with a constructive content. For example, in addition to exchangeable cassettes for processing glue and varnish, it would also be possible to provide further exchangeable cassettes for processing so-called scratches, etc.
