Definitions
- the invention relates to a printing press.
- the invention is therefore based on the object to simplify the arrival and Abstellrea the machines of the prior art.
- the printing machine comprises an anilox roller, with the ink from a paint reservoir can be removed, an inking roller, which decreases ink from the anilox roller, a printing cylinder, which decreases with its printing areas ink from the ink transfer roller and an impression cylinder, which leads a web-shaped substrate. On this substrate, the ink according to the printing areas of the printing cylinder can be applied.
- the printing cylinder operates according to the planographic printing method and it is in its outer periphery, for example by replacing at least parts of the printing cylinder, changeable, wherein the change of the outer circumference of the printing cylinder, the change in the printing length is meant and not the change in the circumference, by removal or mounting a printing plate is caused.
- the printing plates for a printing cylinder which operates on the planographic printing method, are inexpensive to produce, since they can be produced by means of chemical processes.
- rotogravure and flexographic printing forms differ significantly. In gravure printing, this height difference is 10 to 50 microns, with the printing areas are lower than the non-printing areas.
- rollers such as a Verreibewalze for trituration of the ink on the inking roller
- a further roller is not involved in the color guide and therefore not to be understood as a roller for color guidance "within the meaning of the invention Rollers, except for the impression cylinder, belong to an inking unit, to which reference will be made below.
- the printing cylinder In order to apply printing ink on the web-shaped substrate, it is necessary to make the printing cylinder, which is acted upon on its outer periphery with a substantially unyielding pressure plate, to a cylinder with an elastic surface.
- the counter-pressure cylinder which leads the web-shaped printing material, provided with an elastic surface coating, such as a rubber layer, which is compliant.
- the ink transfer cylinder must be provided with an elastic surface, while the printing material leading impression cylinder has an unyielding surface.
- This configuration is advantageous if a particularly stretchable printing material, such as certain plastic films, to be printed. On an unyielding surface even a stretchable substrate experiences no longitudinal forces that can cause a change in length.
- inking roller formatvariabel for example, the effect of stenciling, so the negative image of a printed image part at another location on the substrate, to avoid.
- the ink-carrying cylinders are displaceable along parallel planes.
- all of these cylinders can be moved in a plane which is spanned by the axis of the impression cylinder and the connecting line between the axis of the impression cylinder and the axis of the impression cylinder.
- the ink-guiding cylinders can also be moved in a single plane in which the axis of the impression cylinder is not. This is especially to be provided when several inking units are employed on a common counter-pressure cylinder in order not to let the overall height of such a printing press become too large.
- the printing cylinder, the inking roller and the anilox roller are rotatably mounted in bearing blocks arranged at both ends of the respective rollers, wherein these bearing blocks are displaceable on preferably common rails along a plane.
- the latter two rolls can, if the inking roller is not made variable in size, are stored in common storage blocks, so that the arrival and AbstellRIS is simplified, since now only two bearing blocks are to be moved per page.
- the ink transfer cylinder if this is provided in a printing press according to the invention, stored in its own, independently of the bearing blocks of the pressure roller bearing blocks.
- the two bearing blocks arranged at each end of a roller or a cylinder can be displaceable relative to one another in order to make one end of the cylinder accessible by exposing, while the other end is held in the respective bearing block.
- the relative displaceability is also necessary for a precise adjustment of a roller to another roller.
- rollers and cylinders which are not designed to be format and / or motiwariabel, in the manner described, so in sleeve / mandrel combination, to renew them easily and inexpensively after wear of the surfaces can.
- This relates to the screen and optionally the inking roller, but in particular also the impression cylinder when it is provided with an elastic coating. Especially an elastic coating can be subject to high wear.
- a counter-pressure cylinder is assigned a plurality of inking units.
- the impression cylinder is then centrally located while the individual inking units are arranged around it.
- the inking units may extend substantially radially. But they can also be arranged at an angle to the vertical of the counter-pressure cylinder peripheral surface. The latter is particularly advantageous to limit the height of the printing press.
- This measure leads to a compact printing press. Also avoided with such a printing press, the substrate over stretching without Support to lead, as it is the case with series printing machines, each with only one inking unit per impression cylinder. This measure should be provided especially if an elastic substrate is to be printed.
- This printing material lies immovably on the peripheral surface of the impression cylinder, so that it does not expand, for example, by the action of heat.
- the printing material Regardless of the number of inking units, it is particularly advantageous to guide the printing material over a larger angular range of the impression cylinder on it.
- the printing material nominally touches the impression cylinder only along one line, the so-called printing line. In practice, however, this line expands to an area due to the existing softness of the system, so that the substrate de facto wraps around the impression cylinder over a small angular range.
- a "larger angle range” is not to be understood as meaning an angular range which results from the flexibility of the components of the printing press and which is usually less than 10 °.
- a wrapping angle of at least 90 °, preferably at least 180 ° provided.
- the fixing device is a drying device with which the printing material is subjected to heat.
- each cylinder and each roller can be assigned its own drive, for example an electric motor, in order to be able to adapt the peripheral speeds to each other again after a format change.
- the anilox roller and the inking roller may also be powered by a common motor in an alternative.
- raster and inking rollers may be operated at slightly different peripheral speeds to achieve rubbing of the ink on the inking roller. Trituration or leveling of the ink film on the inking roller, however, can also be done with a rubbing roller or a doctor blade, the latter measure is particularly easy to implement.
- the inking roller, the impression cylinder, the impression cylinder and optionally the ink transfer cylinder in each case run at the same peripheral speeds.
- the printing unit can be tempered in total by being enclosed by a housing or the like and the interior is tempered by supplying appropriately pre-tempered fluid, such as air.
- the rollers and cylinders can also fluid lines, which are traversed by a preheated fluid include, as well as heating elements.
- Other means for temperature control may be provided, such as a nozzle which gives a tempered gas to the ink-carrying rollers.

Abstract
Description
Die Erfindung betrifft eine Druckmaschine.The invention relates to a printing press.
In der Vergangenheit sind zahlreiche Druckmaschinen bekannt geworden, die nach verschiedenen Prinzipien arbeiten. Hervorzuheben sind hierbei Flexo- und Tiefdruckmaschinen, die einen einfachen Farbwerksaufbau mit nur wenigen am Druckprozess beteiligten Walzen aufweisen. Als Nachteil bei solchen Druckmaschinen ist zu nennen, dass die Herstellung der die Druckbilder tragenden Formatwalzen (Flexodruck) bzw. Formzylinder (Tiefdruck) teuer ist. Im Gegenzug sind diese auf oder in diese Walzen oder Zylinder auf- bzw. eingebrachten Motive sehr haltbar. Daher sind beide Druckverfahren besonders bei hohen Druckauflagen sehr wirtschaftlich und in dieser Hinsicht als anderen Druckverfahren überlegen anzusehen.In the past, numerous printing machines have become known which operate on different principles. Of particular note here are flexographic and gravure printing machines, which have a simple inking unit structure with only a few rollers involved in the printing process. A disadvantage of such printing machines is to mention that the production of the format images bearing the images (flexographic) and form cylinder (gravure) is expensive. In return, these on or in these rollers or cylinders on or incorporated motifs are very durable. Therefore, both printing methods, especially at high print runs are very economical and superior in this respect than other printing processes.
Maschinen dieser Art sind bekannt. So zeigt die
Es zeigen sich aber bei den Maschinen des Standes der Technik Nachteile. So ist der An- und Abstellprozess des Druckzylinders, der Farbauftrags- und der Rasterwalze gegeneinander oft sehr kompliziert.However, there are disadvantages in the machines of the prior art. Thus, the on and Abstellprozess the printing cylinder, the inking and the anilox roller is often very complicated.
Der Erfindung liegt daher die Aufgabe zugrunde, den An- und Abstellprozess der Maschinen des Standes der Technik zu vereinfachen.The invention is therefore based on the object to simplify the arrival and Abstellprozess the machines of the prior art.
Diese Aufgabe wird gelöst durch eine Druckmaschine mit den Merkmalen des Anspruchs 1.This object is achieved by a printing machine with the features of claim 1.
Erfindungsgemäß wird diese Aufgabe durch die Merkmale des Anspruchs 1 gelöst. Demnach umfasst die erfindungsgemäße Druckmaschine eine Rasterwalze, mit der Druckfarbe aus einem Farbreservoir entnehmbar ist, eine Farbauftragswalze, welche Druckfarbe von der Rasterwalze abnimmt, einen Druckzylinder, welcher mit seinen druckenden Bereichen Druckfarbe von der Farbübertragungswalze abnimmt und einen Gegendruckzylinder, welcher einen bahnförmigen Bedruckstoff führt. Auf diesen Bedruckstoff ist die Druckfarbe gemäß den druckenden Bereichen des Druckzylinders auftragbar. Darüber hinaus arbeitet der Druckzylinder nach dem Flachdruckverfahren und er ist in seinem Außenumfang, beispielsweise durch Austausch zumindest von Teilen des Druckzylinders, veränderbar, wobei mit der Veränderung des Außenumfangs des Druckzylinder die Veränderung der Drucklänge gemeint ist und nicht die Änderung des Umfanges, die durch Entfernung oder Montage einer Druckplatte hervorgerufen wird.According to the invention, this object is solved by the features of claim 1. Accordingly, the printing machine according to the invention comprises an anilox roller, with the ink from a paint reservoir can be removed, an inking roller, which decreases ink from the anilox roller, a printing cylinder, which decreases with its printing areas ink from the ink transfer roller and an impression cylinder, which leads a web-shaped substrate. On this substrate, the ink according to the printing areas of the printing cylinder can be applied. In addition, the printing cylinder operates according to the planographic printing method and it is in its outer periphery, for example by replacing at least parts of the printing cylinder, changeable, wherein the change of the outer circumference of the printing cylinder, the change in the printing length is meant and not the change in the circumference, by removal or mounting a printing plate is caused.
Die Druckformen für einen Druckzylinder, der nach dem Flachdruckverfahren arbeitet, sind preisgünstig herzustellen, da sie mittels chemischer Verfahren herstellbar sind. Unter Druckformen für Flachdruckverfahren sind dabei solche zu verstehen, die einen Höhenunterschied zwischen druckenden und nicht druckenden Bereichen von bis zu ca. 5 µm (= 0,005 mm), vorzugsweise von bis zu ca. 3 µm (= 0,003 mm) aufweisen, wobei zumeist die nicht druckenden Bereiche gegenüber den druckenden Bereichen erhaben sind (so genannte Negativform). Hiervon unterscheiden sich Tiefdruck- und Flexodruckformen deutlich. Im Tiefdruck beträgt dieser Höhenunterschied 10 bis 50 µm, wobei die druckenden Bereiche tiefer als die nicht druckenden Bereiche liegen. Beim Flexodruck verwendet man so genannte Positivformen, bei denen die druckenden Bereiche gegenüber den nicht druckenden Bereichen erhaben sind. Diese Erhebungen betragen in der Regel zwischen 600 µm bis 3000 µm. Beim Flachdruck werden die druckenden und nicht druckenden Bereiche jedoch nicht nur durch den Höhenunterschied unterschieden, sondern durch die verschiedenen Hafteigenschaften der druckenden und nicht druckenden Bereiche in Bezug auf die Druckfarbe. So haftet die Druckfarbe auf nicht druckenden Bereichen nicht, so dass die Farbauftragswalze keine Farbe an diese Bereiche abgeben kann. Dagegen haftet die Farbe sehr gut an den druckenden Bereichen. In der erfindungsgemäßen Druckmaschine ist zur Beeinflussung der Hafteigenschaften keine Verwendung von Feuchtmitteln vorgesehen. Es handelt sich vielmehr um ein so genanntes wasserloses Flachdruckverfahren. Die unterschiedlichen Hafteigenschaften werden durch die Wahl der Materialien der Druckplatten beeinflusst, wobei die Zusammensetzung und weitere Eigenschaften der Druckfarbe, insbesondere deren Viskosität, und die Materialien der Druckplatten aufeinander abgestimmt sein müssen, um ein möglichst optimales Druckergebnis zu erzielen.The printing plates for a printing cylinder, which operates on the planographic printing method, are inexpensive to produce, since they can be produced by means of chemical processes. Printing forms for planographic printing processes are to be understood as meaning those which have a height difference between printing and non-printing areas of up to about 5 μm (= 0.005 mm), preferably of up to about 3 μm (= 0.003 mm), where usually the non-printing areas are raised compared to the printing areas (so-called negative form). Of these, rotogravure and flexographic printing forms differ significantly. In gravure printing, this height difference is 10 to 50 microns, with the printing areas are lower than the non-printing areas. In flexographic printing, so-called positive forms are used in which the printing areas are raised in relation to the non-printing areas are. These surveys are usually between 600 microns to 3000 microns. However, in planographic printing, the areas of printing and non-printing are distinguished not only by the height difference but by the different adhesive properties of the printing and non-printing areas with respect to the printing ink. Thus, the ink does not adhere to non-printing areas, so that the inking roller can not deliver color to these areas. In contrast, the color adheres very well to the printing areas. In the printing machine according to the invention no use of fountain solutions is provided to influence the adhesive properties. It is rather a so-called waterless planographic printing process. The different adhesive properties are influenced by the choice of the materials of the printing plates, wherein the composition and other properties of the ink, in particular their viscosity, and the materials of the printing plates must be coordinated to achieve the best possible printing result.
Zum Wechseln des Druckformats müssen Teile des Druckzylinders ausgetauscht oder bearbeitet werden, die das Format definieren. Dazu kann der Außenumfang mit Adapterstücken belegt oder der Druckzylinder vollständig ausgetauscht werden. Um aber das Format, insbesondere die Drucklänge ändern zu können, müssen alle Walzen relativ zum Maschinengestell positionsveränderbar sein, wobei jedoch eine einzige Walze, vorzugsweise der Gegendruckzylinder, ortfest verbleiben kann. Um diese Ortsveränderungen einfach zu halten, sind in dem erfindungsgemäßen Druckwerk entweder nur die beschriebenen Walzen zur Farbführung von dem Farbreservoir zum Druckzylinder vorgesehen oder es ist noch zusätzlich ein Farbübertragungszylinder zwischen Druckzylinder und Gegendruckzylinder vorgesehen. Das Vorsehen weiterer Walzen, wie etwa einer Verreibewalze zur Verreibung der Druckfarbe auf der Farbauftragswalze, ist hierdurch jedoch nicht ausgeschlossen, jedoch ist eine solche weitere Walze nicht an der Farbführung beteiligt und daher nicht als Walze zur Farbführung" im Sinne der Erfindung zu verstehen. Alle Walzen, bis auf den Gegendruckzylinder, gehören zu einem Farbwerk, auf das im Folgenden Bezug genommen wird.To change the print format, parts of the impression cylinder that define the format must be exchanged or edited. For this purpose, the outer circumference can be covered with adapter pieces or the impression cylinder can be completely replaced. However, in order to change the format, in particular the printing length, all rollers must be positionally variable relative to the machine frame, but a single roller, preferably the impression cylinder, can remain stationary. In order to keep these changes in location simple, in the printing unit according to the invention, either only the rollers described for ink guide are provided from the ink reservoir to the impression cylinder, or a color transfer cylinder is additionally provided between impression cylinder and impression cylinder. The provision of further rollers, such as a Verreibewalze for trituration of the ink on the inking roller, this is not excluded, however, such a further roller is not involved in the color guide and therefore not to be understood as a roller for color guidance "within the meaning of the invention Rollers, except for the impression cylinder, belong to an inking unit, to which reference will be made below.
Die Kombination von nur wenigen im Druckwerk vorhandenen Walzen, der Formatvariabilität des Druckzylinders und dem Drucken nach einem Flachdruckverfahren, welches vorzugsweise ein wasserloses Flachdruckverfahren ist, führt zu der erfindungsgemäßen Druckmaschine, mit der das Herstellen von Druckprodukten mit einer kleinen Auflage besonders wirtschaftlich ist und die dabei zusätzlich vergleichsweise kompakt aufgebaut ist. Die genannte Kombination ist aus Druckmaschinen nach dem Stand der Technik nicht bekannt.The combination of only a few existing in the printing unit rollers, the format variability of the printing cylinder and printing by a planographic printing process, which is preferably a waterless planographic printing process, leads to the printing machine according to the invention, with the production of printed products with a small number of copies is particularly economical and the case additionally comparatively compact. Said combination is not known from printing machines of the prior art.
Um Druckfarbe auf den bahnförmigen Bedruckstoff aufbringen zu können, ist es notwendig, den Druckzylinder, der an seinem Außenumfang mit einer im wesentlichen unnachgiebigen Druckplatte beaufschlagt ist, an einen Zylinder mit einer elastischen Oberfläche anzustellen. In einer bevorzugten Ausführungsform ist daher der Gegendruckzylinder, welcher den bahnförmigen Bedruckstoff führt, mit einer elastischen Oberflächenbeschichtung, beispielsweise einer Gummischicht, versehen, welche nachgiebig ist. Damit ist bei einem Formatwechsel nur noch der Austausch zumindest von Teilen des Druckzylinders notwendig, während alle anderen Zylinder und Walzen unverändert bleiben können.In order to apply printing ink on the web-shaped substrate, it is necessary to make the printing cylinder, which is acted upon on its outer periphery with a substantially unyielding pressure plate, to a cylinder with an elastic surface. In a preferred embodiment, therefore, the counter-pressure cylinder, which leads the web-shaped printing material, provided with an elastic surface coating, such as a rubber layer, which is compliant. Thus, in a format change only the replacement of at least parts of the printing cylinder is necessary, while all other cylinders and rollers can remain unchanged.
Alternativ kann zwischen Druckzylinder und Gegendruckzylinder noch ein Farbübertragungszylinder vorgesehen sein, der das Druckbild von dem Druckzylinder abnimmt und auf den Bedruckstoff überträgt. In diesem Fall muss der Farbübertragungszylinder mit einer elastischen Oberfläche ausgestattet sein, während der den Bedruckstoff führende Gegendruckzylinder eine unnachgiebige Oberfläche aufweist. Diese Konfiguration ist von Vorteil, wenn ein besonders dehnfähiger Bedruckstoff, etwa bestimmte Kunststofffolien, bedruckt werden soll. Auf einer unnachgiebigen Unterlage erfährt auch ein dehnfähiger Bedruckstoff keine Längskräfte, die eine Längenänderung verursachen können.Alternatively it can be provided between the printing cylinder and the impression cylinder nor a color transfer cylinder, which decreases the printed image of the printing cylinder and transmits to the substrate. In this case, the ink transfer cylinder must be provided with an elastic surface, while the printing material leading impression cylinder has an unyielding surface. This configuration is advantageous if a particularly stretchable printing material, such as certain plastic films, to be printed. On an unyielding surface even a stretchable substrate experiences no longitudinal forces that can cause a change in length.
Es kann jedoch auch von Vorteil sein, die Farbauftragswalze formatvariabel vorzusehen, beispielsweise um den Effekt des Schablonierens, also die negative Abbildung eines Druckbildteiles an einer anderen Stelle auf dem Bedruckstoff, zu vermeiden.However, it may also be advantageous to provide the inking roller formatvariabel, for example, the effect of stenciling, so the negative image of a printed image part at another location on the substrate, to avoid.
Gemäß der Erfindung sind die farbführenden Zylinder entlang paralleler Ebenen verschiebbar. Beispielsweise können alle diese Zylinder in einer Ebene verschoben werden, die von der Achse des Gegendruckzylinders und der Verbindungslinie zwischen der Achse des Gegendruckzylinders und der Achse des Druckzylinders aufgespannt wird. Die farbführenden Zylinder können allerdings auch in einer einzigen Ebene verschoben werden, in der die Achse des Gegendruckzylinders nicht liegt. Dies ist insbesondere dann vorzusehen, wenn mehrere Farbwerke an einen gemeinsamen Gegendruckzylinder angestellt werden, um die Bauhöhe einer solchen Druckmaschine nicht zu groß werden zu lassen.According to the invention, the ink-carrying cylinders are displaceable along parallel planes. For example, all of these cylinders can be moved in a plane which is spanned by the axis of the impression cylinder and the connecting line between the axis of the impression cylinder and the axis of the impression cylinder. However, the ink-guiding cylinders can also be moved in a single plane in which the axis of the impression cylinder is not. This is especially to be provided when several inking units are employed on a common counter-pressure cylinder in order not to let the overall height of such a printing press become too large.
In einer konkreten Ausführungsform sind dabei der Druckzylinder, die Farbauftragswalze und die Rasterwalze in an beiden Enden der jeweiligen Walzen angeordneten Lagerböcken drehbar gelagert, wobei diese Lagerböcke auf vorzugsweise gemeinsamen Schienen entlang einer Ebene verschiebbar sind. Die beiden letztgenannten Walzen können, wenn die Farbauftragswalze nicht formatvariabel ausgeführt ist, in gemeinsamen Lagerböcken gelagert werden, so dass der An- und Abstellprozess vereinfacht wird, da nun pro Seite nur noch zwei Lagerböcke zu verschieben sind. Selbstverständlich ist der Farbübertragungszylinder, wenn dieser in einer erfindungsgemäßen Druckmaschine vorgesehen ist, in eigenen, von den Lagerböcken der Druckwalze unabhängig bewegbaren Lagerböcken gelagert.In a concrete embodiment, the printing cylinder, the inking roller and the anilox roller are rotatably mounted in bearing blocks arranged at both ends of the respective rollers, wherein these bearing blocks are displaceable on preferably common rails along a plane. The latter two rolls can, if the inking roller is not made variable in size, are stored in common storage blocks, so that the arrival and Abstellprozess is simplified, since now only two bearing blocks are to be moved per page. Of course, the ink transfer cylinder, if this is provided in a printing press according to the invention, stored in its own, independently of the bearing blocks of the pressure roller bearing blocks.
Die beiden an jeweils einem Ende einer Walze oder eines Zylinders angeordneten Lagerböcke können relativ zueinander verschiebbar sein, um ein Ende des Zylinders durch Freilegen zugänglich zu gestalten, während das andere Ende in dem betreffenden Lagerbock gehalten wird. Die relative Verschieblichkeit ist allerdings auch für ein genaues Anstellen einer Walze an eine andere Walze notwendig.The two bearing blocks arranged at each end of a roller or a cylinder can be displaceable relative to one another in order to make one end of the cylinder accessible by exposing, while the other end is held in the respective bearing block. However, the relative displaceability is also necessary for a precise adjustment of a roller to another roller.
Um die Format- und/oder die Motivänderung an dem Druckzylinder, aber auch die Formatänderung an dem Farbübertragungszylinder und gegebenenfalls an der Farbauftragwalze einfach und schnell durchführen zu können, ist vorgesehen, diese jeweils in Form eines Druckwalzendoms auszuführen, auf den jeweils Hülsen mit verschiedenen Außendurchmessern, mit verschiedenen Breiten und/oder mit verschiedenen Motiven aufgebracht werden können. Dabei können auch Hülsen auf anderen Hülsen, die auf den Druckwalzendorn aufgebracht wurden, aufgebracht werden. Die Hülsen werden dabei vorteilhafterweise über ein freigelegtes Ende auf den Druckwalzendom aufgeschoben. Die Hülsen können außerhalb der Druckmaschine bearbeitet werden, während der Druckwalzendom in der Druckmaschine verbleiben kann. Auf diese Weise können die Druckformen, die während des Bebilderungsprozesses meist als Platte vorliegen, außerhalb der Druckmaschine, beispielsweise in einem Hilfsgestell, auf eine Hülse aufgezogen und mit dieser fest verbunden bzw. verspannt werden.In order to easily and quickly perform the format and / or the motif change on the printing cylinder, but also the format change to the ink transfer cylinder and optionally to the inking roller, it is intended to perform this each in the form of a pressure roller on the respective sleeves with different outer diameters , can be applied with different widths and / or with different motives. In this case, sleeves can be applied to other sleeves that have been applied to the pressure roller mandrel. The sleeves are thereby advantageously pushed over an exposed end of the Druckwalzendom. The sleeves may be processed outside the printing press while the printing roll dome may remain in the printing press. In this way, the printing plates, which are usually present as a plate during the Bebilderungsprozesses, outside of the printing press, for example, in an auxiliary frame, mounted on a sleeve and firmly connected or braced with this.
Es kann auch vorteilhaft sein, auch die Walzen und Zylinder, die nicht format- und/oder motiwariabel ausgestaltet sind, in der beschriebenen Art, also in Hülse-/Dorn-Kombination, auszugestalten, um sie nach Verschleiß der Oberflächen einfach und kostengünstig erneuern zu können. Dies betrifft die Raster- und gegebenenfalls die Farbauftragswalze, aber insbesondere auch den Gegendruckzylinder, wenn dieser mit einer elastischen Beschichtung versehen ist. Gerade eine elastische Beschichtung kann einem hohen Verschleiß unterliegen.It may also be advantageous to design the rollers and cylinders, which are not designed to be format and / or motiwariabel, in the manner described, so in sleeve / mandrel combination, to renew them easily and inexpensively after wear of the surfaces can. This relates to the screen and optionally the inking roller, but in particular also the impression cylinder when it is provided with an elastic coating. Especially an elastic coating can be subject to high wear.
In einer weiteren vorteilhaften Ausführungsform der Erfindung sind einem Gegendruckzylinder mehrere Farbwerke zugeordnet. Der Gegendruckzylinder ist dann zentral angeordnet, während sich die einzelnen Farbwerke um ihn herum angeordnet sind. Die Farbwerke können sich im Wesentlichen strahlenförmig erstrecken. Sie können aber auch in einem Winkel zur Senkrechten der Gegendruckzylinderumfangsfläche angeordnet sein. Letzteres ist besonders vorteilhaft, um die Bauhöhe der Druckmaschine zu begrenzen. Diese Maßnahme führt zu einer kompakten Druckmaschine. Auch wird mit einer solchen Druckmaschine vermieden, den Bedruckstoff über Strecken ohne Unterstützung zu führen, wie es etwa bei Reihendruckmaschinen mit jeweils nur einem Farbwerk pro Gegendruckzylinder der Fall ist. Diese Maßnahme ist besonders dann vorzusehen, wenn ein dehnbarer Bedruckstoff bedruckt werden soll. Dieser Bedruckstoff liegt unverschiebbar auf der Umfangsfläche des Gegendruckzylinders auf, so dass er sich beispielsweise durch Wärmeeinwirkung nicht ausdehnt.In a further advantageous embodiment of the invention, a counter-pressure cylinder is assigned a plurality of inking units. The impression cylinder is then centrally located while the individual inking units are arranged around it. The inking units may extend substantially radially. But they can also be arranged at an angle to the vertical of the counter-pressure cylinder peripheral surface. The latter is particularly advantageous to limit the height of the printing press. This measure leads to a compact printing press. Also avoided with such a printing press, the substrate over stretching without Support to lead, as it is the case with series printing machines, each with only one inking unit per impression cylinder. This measure should be provided especially if an elastic substrate is to be printed. This printing material lies immovably on the peripheral surface of the impression cylinder, so that it does not expand, for example, by the action of heat.
Unabhängig von der Anzahl der Farbwerke ist es besonders vorteilhaft, den Bedruckstoff über einen größeren Winkelbereich des Gegendruckzylinders auf ihm zu führen. Bei verschiedenen Druckwerken berührt der Bedruckstoff den Gegendruckzylinder nominell nur entlang einer Linie, der so genannten Drucklinie. In der Praxis hingegen weitet sich diese Linie aufgrund der vorhandenen Weichheiten des Systems zu einer Fläche aus, so dass der Bedruckstoff den Gegendruckzylinder de facto über einen kleinen Winkelbereich umschlingt. Unter einem "größeren Winkelbereich" ist allerdings kein Winkelbereich zu verstehen, der von der Nachgiebigkeit der Komponenten der Druckmaschine herrührt und der meist unter 10° liegt.Regardless of the number of inking units, it is particularly advantageous to guide the printing material over a larger angular range of the impression cylinder on it. In the case of different printing units, the printing material nominally touches the impression cylinder only along one line, the so-called printing line. In practice, however, this line expands to an area due to the existing softness of the system, so that the substrate de facto wraps around the impression cylinder over a small angular range. However, a "larger angle range" is not to be understood as meaning an angular range which results from the flexibility of the components of the printing press and which is usually less than 10 °.
So ist in einer besonders vorteilhaften Ausführungsform ein Umschlingungswinkel von mindestens 90°, vorzugsweise mindestens 180° vorzusehen. Bei diesen Umschlingungswinkeln ist es möglich, in Transportrichtung des Bedruckstoffes hinter dem Farbwerk noch eine Fixiereinrichtung vorzusehen, dass der Bedruckstoff auf dem Weg zwischen dem Farbwerk und der Fixiereinrichtung und auch noch hinter der Fixiereinrichtung von dem Gegendruckzylinder geführt wird. Auf diese Weise wird eine Längenausdehnung des Bedruckstoffes vermieden. Dieses ist insbesondere von Vorteil, wenn es sich bei der Fixiereinrichtung um eine Trocknungseinrichtung handelt, mit welcher der Bedruckstoff mit Wärme beaufschlagt wird.Thus, in a particularly advantageous embodiment, a wrapping angle of at least 90 °, preferably at least 180 ° provided. At these wrap angles, it is possible to provide a fixing device in the transport direction of the printing material behind the inking unit, that the printing material is guided on the way between the inking unit and the fixing device and also behind the fixing device of the impression cylinder. In this way, a linear expansion of the printing material is avoided. This is particularly advantageous if the fixing device is a drying device with which the printing material is subjected to heat.
In einer vorteilhaften Ausführungsform der Erfindung kann jedem Zylinder und jeder Walze ein eigener Antrieb, beispielsweise ein Elektromotor, zugeordnet sein, um die Umfangsgeschwindigkeiten nach einem Formatwechsel wieder aneinander anpassen zu können. Die Rasterwalze und die Farbauftragswalze können in einer Alternative auch von einem gemeinsamen Motor angetrieben sein. Auch können Raster- und Farbauftragswalze mit leicht unterschiedlichen Umfangsgeschwindigkeiten betrieben werden, um ein Verreiben der Druckfarbe auf der Farbauftragswalze zu erreichen. Ein Verreiben bzw. Egalisieren des Farbfilms auf der Farbauftragswalze kann allerdings auch mit einer Reibwalze oder einem Rakelmesser erfolgen, wobei letztgenannte Maßnahme besonders einfach zu realisieren ist. Die Farbauftragswalze, der Druckzylinder, der Gegendruckzylinder und gegebenenfalls der Farbübertragungszylinder laufen hingegen in jedem Fall mit gleichen Umfangsgeschwindigkeiten.In an advantageous embodiment of the invention, each cylinder and each roller can be assigned its own drive, for example an electric motor, in order to be able to adapt the peripheral speeds to each other again after a format change. The anilox roller and the inking roller may also be powered by a common motor in an alternative. Also, raster and inking rollers may be operated at slightly different peripheral speeds to achieve rubbing of the ink on the inking roller. Trituration or leveling of the ink film on the inking roller, however, can also be done with a rubbing roller or a doctor blade, the latter measure is particularly easy to implement. The inking roller, the impression cylinder, the impression cylinder and optionally the ink transfer cylinder, however, in each case run at the same peripheral speeds.
Um den gewünschten Farbtransport, der stark von der Viskosität der Druckfarbe und damit von ihrer Temperatur abhängt, zwischen den Walzen, Zylindern und dem Bedruckstoff zu gewährleisten, ist vorgesehen, alle Bereiche, die mit der Farbe in Wärmekontakt stehen, zu temperieren. Dazu zählen neben den Walzen- und Zylinderkörpern und der Rakelkammer auch deren Umgebungsräume, aber auch die Elemente, die mit diesen Körpern in direktem oder indirektem Kontakt stehen. Um eine effektive Temperierwirkung zu erzielen, ist es vorgesehen, solche Bauteile zu temperieren, insbesondere zu kühlen, die, beispielsweise aufgrund von Reibung, Wärme produzieren. Dazu zählen Lager, Zahnräder und Antriebsmotoren. Vorteilhafterweise werden solche Bauteile mit einem Fluid, beispielsweise Wasser oder Öl, umströmt oder durchflossen, um diese Bauteile schnell und genau temperieren zu können. Dazu wird das Fluid entsprechend temperiert, was außerhalb der Druckmaschine erfolgen kann.In order to ensure the desired ink transport, which depends strongly on the viscosity of the printing ink and thus on its temperature, between the rollers, cylinders and the printing material, it is intended to temper all areas which are in thermal contact with the ink. In addition to the cylindrical and cylindrical bodies and the squeegee chamber, these also include their surrounding spaces, but also the elements that are in direct or indirect contact with these bodies. In order to achieve an effective tempering effect, it is provided to temper such components, in particular to cool, which, for example due to friction, produce heat. These include bearings, gears and drive motors. Advantageously, such components with a fluid, such as water or oil, flows around or flowed through to be able to temper these components quickly and accurately. For this purpose, the fluid is appropriately tempered, which can be done outside the printing press.
Auch kann das Druckwerk insgesamt temperiert werden, indem es von einem Gehäuse oder ähnlichem umschlossen wird und der Innenraum durch Zufuhr von entsprechend vortemperiertem Fluid, beispielsweise Luft, temperiert wird. Die Walzen und Zylinder können auch Fluidleitungen, die von einem vortemperierten Fluid durchströmbar sind, umfassen, sowie Heizelemente. Auch andere Mittel zur Temperierung können vorgesehen sein, wie etwa eine Düse, die ein temperiertes Gas auf die farbführenden Walzen gibt.Also, the printing unit can be tempered in total by being enclosed by a housing or the like and the interior is tempered by supplying appropriately pre-tempered fluid, such as air. The rollers and cylinders can also fluid lines, which are traversed by a preheated fluid include, as well as heating elements. Other means for temperature control may be provided, such as a nozzle which gives a tempered gas to the ink-carrying rollers.
