Definitions
- the invention relates to a sheet-fed or roll multicolor rotary printing machine for simultaneous face and reverse printing, in particular for printing the security background on securities, especially banknotes, according to the preamble of patent claim 1.
- Such a printing machine is known from EP-A-0 132 859 in the form of a convertible machine, with which by means of appropriate adjustment of the cylinders either an offset print or a color collective print, in which an image with adjacent colors is produced, can be produced.
- the image is printed using the corresponding bulk printing plate in the form of a high-pressure plate which has the complete printing pattern and is installed on one of the plate cylinders mentioned.
- This high-pressure plate is inked by an ink collecting cylinder, which is formed by a rubber cylinder and in turn receives the colors from several ink selection rollers, the number of which corresponds to the number of colors of an image to be printed.
- the multicolor image is transferred from the colored printing plate to the relevant rubber cylinder. When the printing gap between the two rubber cylinders is passed, the paper is printed on both sides simultaneously with a multicolor image.
- the arrangement is such that the two ink collecting cylinders are practically to the side of the rubber cylinders assigned to them and are only slightly offset relative to them.
- This arrangement of the four large cylinders means that the machine needs a lot, as seen perpendicular to the cylinder axes a lot of space, since the dimensions of the inking unit frames on both sides practically add a length four times a cylinder diameter.
- the colors on each of the ink collecting cylinders are transferred to the plate cylinder carrying the collecting printing plate by means of a special intermediate cylinder in order to take account of the directions of rotation of the cylinders which are necessary because of the convertibility of the machine.
- double inking of the printing plates with the aid of two image transfer cylinders is provided. All these last-mentioned cylinders, plate cylinders, intermediate cylinders and image transfer cylinders are provided on the undersides of the rubber cylinders and the ink collecting cylinders and take up practically the entire space below these four large cylinders.
- an additional offset printing unit preferably a wet offset printing unit, is provided in this known perfecting machine, the plate cylinder of which is in contact with one of the blanket cylinders.
- a multicolored security background can be produced in a single operation using the collective printing process and at the same time a single-colored main pattern using the offset printing process.
- the object of the present invention is to improve a printing machine of the type described above in such a way that all parts of the machine, with the smallest possible overall dimensions, are more accessible, so that the setting up and maintenance of the printing machine is made considerably easier.
- the only Figure 1 shows schematically the embodiment of a sheet printing machine.
- the sheet printing machine shown has an input device supplying the paper 1 in sheet form, which is equipped with a stop drum 2, transfer drums 3 provided with grippers and with a paper dedusting and antistatic device 3 'installed on both sides of the paper 1'.
- the sheets are transferred to a rubber cylinder 4 provided with grippers, which cooperates with a further rubber cylinder 14 which has the same diameter.
- the sheets run between the two blanket cylinders 4 and 14 and are printed on both sides at the same time.
- the cylinders rotate in the directions indicated by arrows. After printing, the sheets are transported by a chain gripper system 24 to a delivery stack or, if appropriate, to a machine that completes the printing.
- the machine is composed of two symmetrical halves.
- Each blanket cylinder 4 and 14 is in contact with a plate cylinder 5 and 15, which is arranged on its lower circumferential region and which has a collecting printing plate 5a or 15a in the form of a high-pressure plate.
- Each of the ink collecting cylinders 6, 16, which are rubber cylinders, works in the example under consideration with four ink selection rollers 8 and 18, which have cut-out reliefs 8a and 18a according to the contour of the areas to be printed in the respective color.
- Each ink selection roller 8, 18 is inked in this color by means of an inking unit 9 or 19.
- the two upper inking units each have a color box, all other inking units each have a double ink box.
- All inking units 9 are located on a removable inking unit frame 12, all inking units 19 on a removable inking unit frame 22.
- the color selection rollers 8, 18 are preferably made of a hard material which does not run the risk of preforming, even if the relief is very fine, so that a security background composed of very fine lines can be obtained.
- the area of the four colors is transferred from the ink selection rollers 8 and 18 to the ink collecting cylinder 6 and 16, on which they are combined and by which they are applied to the respective one Collective printing plate 5a and 15a of the plate cylinder 5 and 15 are transferred.
- This collective printing plate 5a and 15a represents the complete printing pattern to be printed in the four colors, in particular a security background in each case.
- the two complete patterns colored with the different colors are in turn transferred to the rubber cylinders 4 and 14, respectively.
- An automatic blanket washing device 7, 17 is installed below each blanket cylinder 4, 14 and each ink collecting cylinder 6, 16, with which the blankets in question can be washed when there is no printing operation and which, of course, have moved away from these cylinders during the printing operation.
- At least one additional printing unit is provided, the plate cylinder of which cooperates with one of the blanket cylinders 4, 14 and works according to a printing method other than the collective printing method.
- each of the two blanket cylinders 4 and 14 is in contact with the wet offset plate cylinders 10 and 20, each with a wet offset printing unit that is equipped with its own inking unit 11 or 21 and with a dampening unit 11a or 21a.
- An intaglio printing plate, the non-printing surface of which is made ink-repellent by moistening, is preferably used as the wet offset printing plate.
- the one inking unit 11 and the dampening unit 11a are installed on an inking unit frame 13, which is attached to the top of the removable inking unit frame 12 and is moved together with it; the other inking unit 21 and the dampening unit 21a are installed on an inking unit frame 23, which on the Top of the removable inking frame 22 is attached and moved together with it.
- the blanket cylinders 4, 14 transfer the multicolor collective printing patterns which they receive from the printing plates 5a and 15a of the plate cylinders 5 and 15, and at the same time the monochrome images originating from the plate cylinders 10 and 20 of the wet offset printing units, respectively, to the two sides of the paper Images that can overlay the multicolored collective print pattern.
- these images produced by the wet offset printing units are preferably both a main pattern of the banknote and an additional security background, the generally fine lines of which overlay the multicolored security background generated by the collective printing process and therefore a particularly high level of security for the banknote produced lend against counterfeiting.
- a banknote is printed completely on both sides, each with a multicolored security background and a single-color main pattern, the security background consisting of a four-color collective printing pattern and a superimposed one, there is an additional single-color security background pattern, which, like the main pattern, is produced in wet offset printing.
- more than one additional printing unit interacting with each of the blanket cylinders 4 and 14 can of course also be provided be, for example, two or even three printing units.
- these printing units can also work with dry offset or conventional wet offset printing plates.
- the diameter of the rubber cylinders 4 and 14 and the ink collecting cylinders 6 and 16 is an integral multiple, in the example considered three times the diameter of the ink selection rollers 8 and 18 and the plate cylinders 5, 15, 10 and 20.
- the plane that goes through the axes of the cylinders 6 and 4 intersects the plane going through the axes of the cylinders 16 and 14 above the rubber cylinders 4, 14 at an angle, which in the example considered is about 60 °, so that the free space between the ink collecting cylinders 6 and 16 in this case corresponds to almost 1.5 times the cylinder diameter.
- the angle mentioned can be between 40 ° and 120 °, preferably between 50 and 70 °.
- the printing machine according to the invention can also be a web printing machine, in which case the sheet guiding elements are then merely replaced by the known guiding elements for a paper web.

Abstract
Description
Die Erfindung bezieht sich auf eine Bogen- oder Rollen-Mehrfarbenrotationsdruckmaschine zum gleichzeitigen Schön- und Widerdruck, insbesondere zum Druck des Sicherheitsuntergrundes auf Wertpapieren, vor allem Banknoten, gemäss dem Oberbegriff des Patentanspruchs 1.The invention relates to a sheet-fed or roll multicolor rotary printing machine for simultaneous face and reverse printing, in particular for printing the security background on securities, especially banknotes, according to the preamble of patent claim 1.
Eine derartige Druckmaschine ist aus der EP-A-0 132 859 in Form einer konvertierbaren Maschine bekannt, mit welcher durch entsprechende Verstellung der Zylinder entweder ein Offsetdruck oder ein Farbsammeldruck, bei welchem ein Bild mit nebeneinanderliegenden Farben entsteht, herstellbar ist. Im Falle des Farbsammeldrucks wird das Bild mit Hilfe der entsprechenden Sammeldruckplatte in Form einer Hochdruckplatte gedruckt, die das vollständige Druckmuster aufweist und auf einem der erwähnten Plattenzylinder installiert ist. Diese Hochdruckplatte wird durch einen Farbsammelzylinder eingefärbt, der von einem Gummizylinder gebildet wird und seinerseits die Farben von mehreren Farbselektionswalzen erhält, deren Anzahl der Zahl der Farben eines zu druckenden Bildes entspricht. Von der eingefärbten Sammeldruckplatte wird das Mehrfarbenbild auf den betreffenden Gummizylinder übertragen. Beim Passieren des Druckspalts zwischen beiden Gummizylindern wird das Papier gleichzeitig auf beiden Seiten mit je einem Mehrfarbenbild bedruckt.Such a printing machine is known from EP-A-0 132 859 in the form of a convertible machine, with which by means of appropriate adjustment of the cylinders either an offset print or a color collective print, in which an image with adjacent colors is produced, can be produced. In the case of color bulk printing, the image is printed using the corresponding bulk printing plate in the form of a high-pressure plate which has the complete printing pattern and is installed on one of the plate cylinders mentioned. This high-pressure plate is inked by an ink collecting cylinder, which is formed by a rubber cylinder and in turn receives the colors from several ink selection rollers, the number of which corresponds to the number of colors of an image to be printed. The multicolor image is transferred from the colored printing plate to the relevant rubber cylinder. When the printing gap between the two rubber cylinders is passed, the paper is printed on both sides simultaneously with a multicolor image.
Bei dieser bekannten Schön- und Widerdruckmaschine ist die Anordnung so getroffen, dass die beiden Farbsammelzylinder praktisch seitlich neben den ihnen zugeordneten Gummizylindern liegen und gegenüber diesen nur ganz wenig nach unten versetzt sind. Durch diese Anordnung der vier grossen Zylinder benötigt die Maschine, senkrecht zu den Zylinderachsen gesehen, sehr viel Platz, da sich zu den Abmessungen der Farbwerkgestelle auf beiden Seiten praktisch eine dem Vierfachen eines Zylinderdurchmessers entsprechende Länge addiert. Die Farben auf jedem der Farbsammelzylinder werden, um den wegen der Konvertierbarkeit der Maschine erforderlichen Drehrichtungen der Zylinder Rechnung zu tragen, mittels je eines besonderen Zwischenzylinders auf den die Sammeldruckplatte tragenden Plattenzylinder übertragen. Ausserdem ist eine doppelte Einfärbung der Sammeldruckplatten mit Hilfe zweier Bildübertragungszylinder vorgesehen. Alle diese zuletzt erwähnten Zylinder, Plattenzylinder, Zwischenzylinder und Bildübertragungszylinder, sind an den Unterseiten der Gummizylinder und der Farbsammelzylinder vorgesehen und nehmen praktisch den gesamten Platz unterhalb dieser vier grossen Zylinder ein.In this known perfecting machine, the arrangement is such that the two ink collecting cylinders are practically to the side of the rubber cylinders assigned to them and are only slightly offset relative to them. This arrangement of the four large cylinders means that the machine needs a lot, as seen perpendicular to the cylinder axes a lot of space, since the dimensions of the inking unit frames on both sides practically add a length four times a cylinder diameter. The colors on each of the ink collecting cylinders are transferred to the plate cylinder carrying the collecting printing plate by means of a special intermediate cylinder in order to take account of the directions of rotation of the cylinders which are necessary because of the convertibility of the machine. In addition, double inking of the printing plates with the aid of two image transfer cylinders is provided. All these last-mentioned cylinders, plate cylinders, intermediate cylinders and image transfer cylinders are provided on the undersides of the rubber cylinders and the ink collecting cylinders and take up practically the entire space below these four large cylinders.
Ausserdem ist bei dieser bekannten Schön- und Widerdruckmaschine ein zusätzliches Offsetdruckwerk, vorzugsweise ein Nassoffsetdruckwerk, vorgesehen, dessen Plattenzylinder mit einem der Gummizylinder in Berührung steht. Auf diese Weise lassen sich bei Wertscheinen, insbesondere Banknoten, in einem einzigen Arbeitsgang ein mehrfarbiger Sicherheitsuntergrund nach dem Sammeldruckverfahren und gleichzeitig ein einfarbiges Hauptmuster nach dem Offsetdruckverfahren herstellen.In addition, an additional offset printing unit, preferably a wet offset printing unit, is provided in this known perfecting machine, the plate cylinder of which is in contact with one of the blanket cylinders. In this way, in the case of notes, in particular banknotes, a multicolored security background can be produced in a single operation using the collective printing process and at the same time a single-colored main pattern using the offset printing process.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Druckmaschine des vorstehend beschriebenen Typs derart zu verbessern, dass alle Teile der Maschine, bei möglichst geringer Gesamtabmessung, besser zugänglich sind, so dass das Einrichten und die Wartung der Druckmaschine wesentlich erleichtert wird.The object of the present invention is to improve a printing machine of the type described above in such a way that all parts of the machine, with the smallest possible overall dimensions, are more accessible, so that the setting up and maintenance of the printing machine is made considerably easier.
Diese Aufgabe wird erfindungsgemäss durch die im kennzeichnenden Teil des Anspruchs 1 angegebenen Merkmale gelöst.This object is achieved according to the invention by the features specified in the characterizing part of claim 1.
Zweckmässige Ausgestaltungen der Druckmaschine nach der Erfindung ergeben sich aus den abhängigen Ansprüchen.Appropriate configurations of the printing press according to the invention result from the dependent claims.
Die Erfindung wird anhand der Zeichnung an einem Ausführungsbeispiel näher erläutert.The invention is explained in more detail with the aid of an embodiment.
Die einzige Figur 1 zeigt schematisch das Ausführungsbeispiel einer Bogendruckmaschine.The only Figure 1 shows schematically the embodiment of a sheet printing machine.
Die dargestellte Bogendruckmaschine hat eine das Papier 1 in Bogenform zuführende Eingangsvorrichtung, die mit einer Stopptrommel 2, mit Greifern versehenen Ueberführungstrommeln 3 und mit einer auf beiden Seiten des Papiers 1 installierten Papier-Entstaubungs- und Antistatikvorrichtung 3′ ausgerüstet ist. Die Bögen werden auf einen mit Greifern versehenen Gummizylinder 4 überführt, der mit einem weiteren Gummizylinder 14, der den gleichen Durchmesser hat, zusammenwirkt. Die Bögen laufen zwischen beiden Gummizylindern 4 und 14 hindurch und werden dabei gleichzeitig auf beiden Seiten bedruckt. Die Zylinder drehen sich in den durch Pfeile angegebenen Richtungen. Nach dem Bedrucken werden die Bögen durch ein Kettengreifersystem 24 auf einen Auslagestapel oder gegebenenfalls zu einer den Druck vervollständigenden Maschine transportiert.The sheet printing machine shown has an input device supplying the paper 1 in sheet form, which is equipped with a
Mit Ausnahme der die Bögen transportierenden Einrichtungen ist die Maschine aus zwei symmetrischen Hälften zusammengesetzt.With the exception of the devices that transport the sheets, the machine is composed of two symmetrical halves.
Jeder Gummizylinder 4 und 14 steht mit einem an seinem unteren Umfangsbereich angeordneten Plattenzylinder 5 bzw. 15 in Berührung, der eine Sammeldruckplatte 5a bzw. 15a in Form einer Hochdruckplatte trägt.Each
Unterhalb der Gummizylinder 4, 14 und der Plattenzylinder 5, 15, symmetrisch nach aussen versetzt, befinden sich zwei im Abstand voneinander installierte Farbsammelzylinder 6 und 16, die denselben Durchmesser wie die Gummizylinder 4, 14 haben und von denen der eine den Plattenzylinder 5 und der andere den Plattenzylinder 15 berührt.Below the
Jeder der Farbsammelzylinder 6, 16, bei denen es sich um Gummizylinder handelt, arbeitet im betrachteten Beispiel mit vier Farbselektionswalzen 8 bzw. 18 zusammen, welche ausgeschnittene Reliefs 8a bzw. 18a entsprechend der Kontur der in der betreffenden Farbe zu druckenden Bereiche aufweisen. Jede Farbselektionswalze 8, 18 wird mittels eines Farbwerks 9 bzw. 19 in dieser Farbe eingefärbt. Im betrachteten Beispiel haben die beiden oberen Farbwerke je einen Farbkasten, alle übrigen Farbwerke je einen Doppelfarbkasten. Alle Farbwerke 9 befinden sich auf einem abfahrbaren Farbwerkgestell 12, alle Farbwerke 19 auf einem abfahrbaren Farbwerkgestell 22.Each of the
Die Farbselektionswalzen 8, 18, sind vorzugsweise aus einem harten Material hergestellt, welches nicht Gefahr läuft, sich zu vorformen, selbst wenn das Relief sehr fein ist, so dass ein aus sehr feinen Linien zusammengesetzter Sicherheitsuntergrund erhalten werden kann.The
Die Bereich der vier Farben werden von den Farbselektionswalzen 8 bzw. 18 auf den Farbsammelzylinder 6 bzw. 16 übertragen, auf welchem sie vereinigt und durch den sie auf die betreffende Sammeldruckplatte 5a bzw. 15a des Plattenzylinders 5 bzw. 15 übertragen werden. Diese Sammeldruckplatte 5a bzw. 15a stellt das vollständige, in den vier Farben zu druckende Druckmuster, insbesondere je einen Sicherheitsuntergrund dar. Die beiden vollständigen, mit den verschiedenen Farben eingefärbten Muster werden ihrerseits auf die Gummizylinder 4 bzw. 14 übertragen.The area of the four colors is transferred from the
Unterhalb jedes Gummizylinders 4, 14 und jedes Farbsammelzylinders 6, 16 ist je eine automatische Gumituch-Wascheinrichtung 7, 17 installiert, mit denen die betreffenden Gummitücher gewaschen werden können, wenn kein Druckbetrieb stattfindet, und welche während des Druckbetriebs natürlich von diesen Zylindern abgerückt sind.An automatic blanket washing device 7, 17 is installed below each
Ferner ist wenigstens ein zusätzliches Druckwerk vorgesehen, dessen Plattenzylinder mit einem der Gummizylinder 4, 14 zusammenwirkt und nach einem anderen Druckverfahren als dem Sammeldruckverfahren arbeitet.Furthermore, at least one additional printing unit is provided, the plate cylinder of which cooperates with one of the
Im betrachteten Beispiel steht jeder der beiden Gummizylinder 4 und 14 mit dem Nassoffsetplattenzylinder 10 bzw. 20 je eines Nassoffsetdruckwerks in Berührung, das mit einem eigenen Farbwerk 11 bzw. 21 und mit einem Feuchtwerk 11a bzw. 21a ausgerüstet ist. Als Nassoffsetdruckplatte dient vorzugsweise eine Stichtiefdruckplatte, deren nichtdruckende Oberfläche durch Anfeuchtung farbabstossend gemacht wird. Das eine Farbwerk 11 und das Feuchtwerk 11a sind auf einem Farbwerkgestell 13 installiert, welches auf der Oberseite des abfahrbaren Farbwerkgestells 12 befestigt ist und mit diesem gemeinsam bewegt wird; das andere Farbwerk 21 und das Feuchtwerk 21a sind auf einem Farbwerkgestell 23 installiert, welches auf der Oberseite des abfahrbaren Farbwerkgestells 22 befestigt ist und gemeinsam mit diesem bewegt wird.In the example under consideration, each of the two
Die Gummizylinder 4, 14 übertragen die mehrfarbigen Sammeldruckmuster, die sie von den Sammeldruckplatten 5a bzw. 15a der Plattenzylinder 5 bzw. 15 erhalten, und gleichzeitig die jeweils von den Plattenzylindern 10 bzw. 20 der Nassoffsetdruckwerke herrührenden einfarbigen Bilder auf die beiden Papierseiten, wobei diese Bilder das mehrfarbige Sammeldruckmuster überlagern können. Beim Banknotendruck handelt es sich bei diesen von den Nassoffsetdruckwerken erzeugten Bildern vorzugsweise jeweils sowohl um ein Hauptmuster der Banknote als auch um einen zusätzlichen Sicherheitsuntergrund, dessen im allgemeinen feine Linien den mehrfarbigen, nach dem Sammeldruckverfahren erzeugten Sicherheitsuntergrund überlagern und daher der hergestellten Banknote eine besonders hohe Sicherheit gegen Fälschung verleihen. Man erhält also mit der dargestellten Druckmaschine nach der Erfindung in einer einzigen Druckoperation und bei einem einzigen Durchlauf des Papiers eine auf beiden Seiten vollständig mit je einem mehrfarbigen Sicherheitsuntergrund und einem einfarbigen Hauptmuster bedruckte Banknote, wobei der Sicherheitsuntergrund aus einem vierfarbigen Sammeldruckmuster und einem diesem überlagerten, zusätzlichen einfarbigen Sicherheitsuntergrundmuster besteht, welches, wie auch das Hauptmuster, im Nassoffsetdruck erzeugt wird.The
Da aufgrund der besondern Anordnung aller Zylinder längs der Oberfläche der beiden Gummizylinder 4 und 14 genügend freier Raum besteht, können natürlich auch mehr als nur jeweils ein zusätzliches, mit jedem der Gummizylinder 4 und 14 zusammenwirkendes Druckwerk vorgesehen werden, beispielsweise jeweils zwei oder gar drei Druckwerke. Anstelle mit Stichdruckplatten, die besonders feine und nuancenreiche Muster und Bilder herzustellen erlauben, können diese Druckwerke auch mit Trockenoffset- oder üblichen Feuchtoffsetdruckplatten arbeiten.Since there is enough free space due to the special arrangement of all cylinders along the surface of the two
Der Durchmesser der Gummizylinder 4 und 14 sowie der Farbsammelzylinder 6 und 16 beträgt ein ganzzahliges Vielfaches, im betrachteten Beispiel das Dreifache, des Durchmessers der Farbselektionswalzen 8 und 18 und der Plattenzylinder 5, 15, 10 und 20.The diameter of the
Die Ebene, die durch die Achsen der Zylinder 6 und 4 geht, schneidet die durch die Achsen der Zylinder 16 und 14 gehende Ebene oberhalb der Gummizylinder 4, 14 in einem Winkel, der im betrachteten Beispiel etwa 60° beträgt, so dass der freie Raum zwischen den Farbsammelzylindern 6 und 16 in diesem Falle knapp 1,5 mal dem Zylinderdurchmesser entspricht. Allgemein kann der erwähnte Winkel zwischen 40° und 120°, vorzugsweise zwischen 50 und 70° betragen. Eine solche Anordnung erlaubt eine gute Zugänglichkeit zu allen Zylindern, was bei der Einrichtung der Druckmaschine und ihrer Wartung wichtig ist, vermeidet jedoch gleichzeitig einen unerwünscht grossen Platzbedarf der Druckmaschine.The plane that goes through the axes of the
Die Druckmaschine nach der Erfindung kann auch eine Rollendruckmaschine sein, wobei dann die Bogenführungsorgane lediglich durch die bekannten Führungsorgane für eine Papierbahn ersetzt sind.The printing machine according to the invention can also be a web printing machine, in which case the sheet guiding elements are then merely replaced by the known guiding elements for a paper web.
