Abstract

Bei einem Druckwerk in einer Rotationsdruckmaschine für Schön- und Widerdruck, bestehend aus Farbwerk, Plattenzylinder und Gegendruckzylinder, wird der Gegendruckzylinder wahlweise mit einem "weichen" oder "harten" Mantel (27) versehen.In the case of a printing unit in a rotary printing press for surface and offset printing, consisting of the inking unit, plate cylinder and impression cylinder, the impression cylinder is optionally provided with a "soft" or "hard" jacket (27).

Description

Die Erfindung betrifft ein Druckwerk mit Kurzfarbwerk gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a printing unit with a short inking unit according to the preamble of patent claim 1.

Es gehört zum Stand der Technik bei der Verwendung von Wasserfarben oder wasserlöslichen Flexofarben "weiche" Druckplatten auf dem Plattenzylinder zu benutzen. In diesem Fall muß der mit dem Plattenzylinder zusammenwirkende Gegendruckzylinder eine "harte" und gleichzeitig zumindest beim Widerdruck eine farbabstoßende Oberfläche aufweisen, die vorzugsweise mit Chrom beschichtet ist. Dieser Aufbau von abwechselnd zusammenwirkenden "weichen" und "harten" Zylindern kann mit "Hart - Weich - Hart -System" bezeichnet werden. Eine Verwendung von Wasserfarbe in einem anderen System mit harter Druckplatte und weichem bzw. weich bespanntem Gegendruckzylinder ist aufgrund der starken Affinität von Gummi auf wasserhaltige Druckfarben nicht möglich, da sich insbesondere im Widerdruckbetrieb in kürzester Zeit eine Schicht aus angetrockneter Druckfarbe auf dem Gegendruckzylinder aufbaut, die die Qualität des Druckproduktes in hohem Maße beeinträchtigt. Bei der Verwendung von ölhaltigen Druckfarben oder ölverdünnbaren Druckfarben werden harte Druckplatten auf dem Plattenzylinder verwendet. Diese verlangen jedoch einen "weichen" Gegendruckzylinder. Die Tatsache, daß die chrombeschichtete Oberfläche des Gegendruckzylinders nicht ölabweisend ist, macht sich nicht so stark bemerkbar, da die Ölfarbenschicht, die sich auf dem Gegendruckzylinder im Widerdruckbetrieb aufbaut, infolge der bekannten Farbspaltung vernachlässigbar klein ist. Es entsteht bei einer Rotationsdruckmaschine somit der Nachteil, daß eine Änderung der Druckfarbe von wasserhaltige auf ölhaltige Druckfarbe oder umgekehrt, wegen der Oberflächenbeschaffenheit der Gegendruckzylinder nicht möglich ist. Die Gegendruckzylinder in einer Maschine zu wechseln, ist aufgrund ihrer Größe nur unter schwierigsten Bedingungen bei großem Zeitaufwand möglich.It is state of the art to use "soft" printing plates on the plate cylinder when using water colors or water-soluble flexo colors. In this case, the impression cylinder interacting with the plate cylinder must have a "hard" surface and at the same time, at least during backprinting, an ink-repellent surface, which is preferably coated with chrome. This structure of alternately interacting "soft" and "hard" cylinders can be referred to as a "hard - soft - hard system". The use of water color in another system with a hard printing plate and a soft or soft-covered impression cylinder is not possible due to the strong affinity of rubber for water-based printing inks, since a layer of dried printing ink builds up on the impression cylinder in a very short time, especially in reverse printing operation the quality of the printed product is greatly impaired. When using oil-based printing inks or oil-thinnable printing inks, hard printing plates are used on the plate cylinder. However, these require a "soft" impression cylinder. The fact that the chrome coated surface of the impression cylinder is not Oil-repellent is not so noticeable, since the oil paint layer that builds up on the impression cylinder in reverse printing operation is negligibly small due to the known ink splitting. The disadvantage of a rotary printing press is that changing the printing ink from water-based to oil-containing printing ink or vice versa is not possible because of the surface properties of the impression cylinders. Due to their size, changing the impression cylinders in a machine is only possible under the most difficult conditions and takes a lot of time.

Der Erfindung liegt die Aufgabe zugrunde, ein Druckwerk mit einem Kurzfarbwerk in einer Rotationsdruckmaschine für Schön- und Widerdruck zu schaffen, bei dem es möglich ist, wahlweise "harte" oder "weiche" Druckplatten auf dem Plattenzylinder zu verwenden.The invention has for its object to provide a printing unit with a short inking unit in a rotary printing machine for face and back printing, in which it is possible to use either "hard" or "soft" printing plates on the plate cylinder.

Die Aufgabe wird durch den kennzeichnenden Teil des Patentanspruchs 1 gelöst.The object is achieved by the characterizing part of patent claim 1.

Die mit der Erfindung erzielbaren Vorteile liegen insbesondere darin, daß eine für Schön- und Widerdruck gebaute Rotationsdruckmaschine, je nach Marktlage, d. h. nach Angebot und Preislage von Druckplatten entweder mit "weichen" bzw. "harten" Druckplatten ausgerüstet werden kann. Zusätzlich erlaubt die Unabhängigkeit von einer Druckfarbenart, wasserhaltig oder ölhaltig, eine freie Kalkulation für die Materialbeschaffung unter den jeweils günstigsten Marktbedingungen.The advantages that can be achieved with the invention are, in particular, that a rotary printing press built for face and back printing, depending on the market situation, ie on the offer and price range of printing plates, can be equipped with either "soft" or "hard" printing plates. In addition, independence from a type of printing ink, water-based or oil-based, allows a free calculation for material procurement under the most favorable market conditions.

Eine Rotationsdruckmaschine weist in einer Druckeinheit 1 zwei parallel nebeneinander angeordnete Druckwerke 2 und 3 für Schön- und Widerdruck mit jeweils einem Kurzfarbwerk 4; 6 auf. Jedes Kurzfarbwerk 4; 6 besteht jeweils aus einer Rasterwalze 7; 8 und einem Farbwerk 9; 11 z. B. einem Spülfarbwerk wie es die DE-PS 33 20 638 zeigt. Die Rasterwalze 7; 8 wirkt in bekannter Weise mit einem Plattenzylinder 12; 13 und dieser in bekannter Weise mit einem Gegendruckzylinder 14; 16 zusammen. Eine von unten der Druckeinheit 1 zugeführte Papierbahn 17 wird zunächst von einer verchromten Walze 18 umgelenkt und einem Druckspalt zwischen Plattenzylinder 12 und Gegendruckzylinder 14 zugeführt, in dem die Papierbahn 17 im Schöndruckbetrieb bedruckt wird. Vom Druckzylinder 12 gelangt die Papierbahn 17 mittels zweier verchromter Umlenkwalzen 19, 21 von unten in einen zweiten Druckspalt zwischen dem zweiten Plattenzylinder 13 und dem zweiten Ggendruckzylinder 16, in der diese im Widerdruckbetrieb bedruckt wird. Die Gegendruckzylinder 14; 16 weisen an ihrem Umfang je eine achsparallele Grube 22, 23 mit jeweils einer Einrichtung 24 zum Spannen einer Gegendruckplatte 27 und eines Untertuches 28 auf. In der Grube 22; 23 sind drei nahezu grubenlange Spannwellen 29, 31, 32 nebeneinanderliegend angeordnet. Die beiden äußeren Spannwellen 29, 32 dienen dem Spannen des Untertuches 28 und weisen jeweils eine Längsnut 33, 34 zur Aufnahme eines Untertuchendes 36, 37 auf. Die mittlere Spannwelle 31 weist zwei gegenüberliegende Längsnuten 38; 39 zur Aufnahme von Gegendruckplattenenden 41; 42 auf. Des Untertuch 28 besteht aus einem elastischen Material, vorwiegend Kork, Leinen oder einem Gewebe aus Gummi und Textilien, je nach Stärke der gegebenen Druckkräfte. Die Dicke des Untertuches 28 ist abhängig von der Dicke des Drucktuches 27, so daß eine Gesamtdicke von Untertuch 28 und Drucktuch 27 ein vorgegebenes konstantes Maß z. B. 3,3 mm nicht überschreitet. Die Untertuchenden 36; 37 sind umgeklappt und auf das Untertuch 28 genäht, so daß sich an jedem Untertuchende 36; 37 eine Schlaufe 40, 45 zur Aufnahme eines Haltedrahtes 43; 44 ergibt. Das Untertuch 28 ist in dem Bereich, der den Druckzylinder 14; 16 umgibt verstärkt ausgeführt, so daß sich dort eine größere Dicke des Untertuches ergibt als an den Untertuchenden 36; 37. Das Material der Gegendruckplatte 27 oder zumindest deren Mantel 27 ist abhängig, welche Anforderungen an die Oberfläche 26 des Druckzylinders 14; 16 gestellt werden, entweder hart oder weich, farb- oder wasserabstoßend, oleo- oder hydrophil.A rotary printing press has in a printing unit 1 two printing units 2 and 3 arranged in parallel next to one another for perfecting and reverse printing, each with a short inking unit 4; 6 on. Each short inking unit 4; 6 each consists of an anilox roller 7; 8 and an inking unit 9; 11 z. B. a flushing inking unit as shown in DE-PS 33 20 638. The anilox roller 7; 8 acts in a known manner with a plate cylinder 12; 13 and this in a known manner with an impression cylinder 14; 16 together. A paper web 17 fed from below to the printing unit 1 is first deflected by a chrome-plated roller 18 and is fed to a printing nip between the plate cylinder 12 and the impression cylinder 14, in which the paper web 17 is printed in straight printing mode. From the printing cylinder 12, the paper web 17 passes from below into a second printing nip between the second by means of two chromed deflection rollers 19, 21 Plate cylinder 13 and the second counter-pressure cylinder 16, in which it is printed in reverse printing operation. The impression cylinder 14; 16 each have on their circumference an axially parallel pit 22, 23, each with a device 24 for tensioning a counterpressure plate 27 and a subcloth 28. In the pit 22; 23 are three nearly pit-long tension shafts 29, 31, 32 arranged side by side. The two outer tensioning shafts 29, 32 serve to tension the undercloth 28 and each have a longitudinal groove 33, 34 for receiving an undercloth end 36, 37. The middle tension shaft 31 has two opposite longitudinal grooves 38; 39 for receiving counter-pressure plate ends 41; 42 on. The undercloth 28 consists of an elastic material, predominantly cork, linen or a fabric made of rubber and textiles, depending on the strength of the given compressive forces. The thickness of the blanket 28 is dependent on the thickness of the blanket 27, so that a total thickness of the blanket 28 and blanket 27 a predetermined constant dimension z. B. does not exceed 3.3 mm. The examiner 36; 37 are folded down and sewn onto the undercloth 28, so that 36; 37 a loop 40, 45 for receiving a holding wire 43; 44 results. The undercloth 28 is in the area that the printing cylinder 14; 16 surrounds reinforced, so that there is a greater thickness of the undercloth than at the Untertuchenden 36; 37. The material of the counter-pressure plate 27 or at least its jacket 27 depends on the requirements for the surface 26 of the printing cylinder 14; 16, either hard or soft, color or water repellent, oleo- or hydrophilic.

Sollen nun "harte" Druckplatten (ca. 90 Shore D) auf dem Plattenzylinder 12; 13 eingesetzt werden, wird ein weicher Gegendruckzylinder 14; 16 zumindest aber ein weicher Mantel 27 auf dem Gegendruckzylinder 14; 16 verlangt. In diesem Fall können bekannte Gummitücher mit aufvulkanisierten Glasperlen verwendet werden. Werden nun jedoch weiche Druckplatten (ca. 60 Shore A) auf dem Plattenzylinder 12, 13 eingesetzt, wird verlangt, daß die Oberfläche des Druckzylinder 14; 16 hart und farbabstoßend ist, wie das auch beim Verdrucken von Wasserfarben notwendig ist. In diesem Fall wird die Gegendruckplatte 27 z. B. eine Trimetallplatte 46 über das Untertuch 28 auf den Druckzylinder 14; 16 gespannt. Die Trimetallplatte 46 hat eine Dicke von ca. 0,3 mm und besteht z. B. aus Stahl, Kupfer und Chrom auf der Außenschicht. Die Gegendruckplatte 27 kann auch aus Kunststoff oder Nylongewebe bestehen. Damit diese leicht aufgespannt werden kann sind an beiden Enden der Gegendruckplatte 27 elastische Tücher (z. B. Leinen) angenietet und an ihren Enden mit je einer Zwickschiene 47; 48 versehen. Die Länge der Gegendruckplatte 27 ist so ausgelegt, daß die Nietstellen 49; 51 nicht auf dem Druckzylinderumfang zu liegen kommen, sondern in die Grube 22; 28 hineinragen.Are now "hard" printing plates (approx. 90 Shore D) on the plate cylinder 12; 13 are used, a soft impression cylinder 14; 16 but at least a soft jacket 27 on the impression cylinder 14; 16 requests. In this case, known rubber blankets with vulcanized glass beads can be used. However, if soft printing plates (approx. 60 Shore A) are used on the plate cylinder 12, 13, it is required that the surface of the printing cylinder 14; 16 is hard and ink-repellent, as is also necessary when printing water colors. In this case, the pressure plate 27 z. B. a tri-metal plate 46 over the sub-cloth 28 on the impression cylinder 14; 16 excited. The tri-metal plate 46 has a thickness of approximately 0.3 mm and consists, for. B. made of steel, copper and chrome on the outer layer. The counter pressure plate 27 can also consist of plastic or nylon fabric. So that it can be easily stretched 27 elastic cloths (z. B. linen) are riveted to both ends of the counter-pressure plate and each with a lasting rail 47; 48 provided. The length of the pressure plate 27 is designed so that the rivet points 49; 51 do not come to rest on the pressure cylinder circumference, but in the pit 22; 28 protrude.

Zum Bespannen des Gegendruckzylinders 14; 16 werden zunächst die Schlaufen 40; 45 des Untertuches 28 mit den in die Schlaufen 40; 45 eingeführten Haltedrähten 43; 44 in die Längsnuten 33; 34 eingesteckt und durch Verdrehen der Spannwellen 29; 31 gespannt und in Spannstellung arretiert. Die erste Zwickschiene 47 der Gegendruckplatte 27 wird in den zunächst nach oben weisenden Schlitz 38 der Spannwelle 31 eingesteckt und um eine halbe Umdrehung in bzw. gegen den Uhrzeigersinn weitergedreht, bis der gegenüberliegende Schlitz 39 nach oben weist. In den Schlitz 39 wird die zweite Zwickschiene 48 der Gegendruckplatte 27 eingesteckt. Durch Weiterdrehen der Spannwelle 31 in bzw. gegen den Uhrzeigersinn werden beide Drucktuchenden 41, 42 gelängt und dadurch wird die Gegendruckplatte 27 auf dem Gegendruckzylinder 14; 16 gespannt. Die Spannwelle 31 wird in Spannstellung arretiert.For covering the impression cylinder 14; 16, the loops 40; 45 of the undercloth 28 with the in the loops 40; 45 inserted retaining wires 43; 44 in the longitudinal grooves 33; 34 inserted and by rotating the tension shafts 29; 31 cocked and locked in the cocking position. The first lasting rail 47 of the counterpressure plate 27 is in the slot 38, which initially points upward Tensioning shaft 31 inserted and turned a half turn clockwise or counterclockwise until the opposite slot 39 points upward. The second lasting rail 48 of the counter-pressure plate 27 is inserted into the slot 39. By rotating the tension shaft 31 clockwise or counterclockwise, both blanket ends 41, 42 are elongated and thereby the counter pressure plate 27 on the counter pressure cylinder 14; 16 excited. The tensioning shaft 31 is locked in the tensioning position.
