Description

Die Erfindung betrifft eine Druckmaschine mit einer bogenführenden Fläche, bei der die bogenführende Fläche zumindest in einem Teilbereich derselben eine mit Durchgangsöffnungen versehene Deckfläche eines Blas- bzw. Saugkastens bildet.The invention relates to a printing press with a sheet-guiding surface, in which the sheet-guiding surface forms at least in a partial area thereof a top surface of a blower or suction box provided with through openings.

Es ist bekannt, zur sicheren Bogenführung Teilbereiche von bogenführenden Flächen als mit Durchgangsöffnungen versehene Deckflächen von Blas- bzw. Saugkästen auszubilden; siehe beispielsweise EP-A-0 495 320. Insbesondere in den Krümmungsbereichen der Auslegetrommel eines Kettenauslegers bzw. des vorangegangenen Druckzylinders des letzten Druckwerks erfahren bedruckte Papierbögen sehr starke Umlenkungen. Dabei ist zu beobachten, daß die Papierbogen in ihrem hinteren Bogenbereich aufgrund der extremen Krümmungen leicht ihre bogenführende Fläche verlassen. Hierbei sind Beschädigungen des Druckbildes und des Papierbogens nicht auszuschließen. Bei geringen Fördergeschwindigkeiten ist zu beobachten, daß die Bogenhinterkante im Bereich der Auslegetrommel, in dem der Papierbogen mit seiner Vorderkante von der Auslegetrommel übernommen wird und in den dann die Vorderkante unter Richtungswechsel unter den hinteren Bogenbereich hindurchgeführt wird, regelrecht in Richtung der Achse der Auslegetrommel einklappt und so an Elementen der Auslegetrommel beschädigt werden kann. Bei kurzfristigem Maschinenstopp können die Papierbogen bei der bekannten Ausgestaltung eines Saugkastens in den Mittenbereich der Auslegetrommel kippen. Das Einklappen der Papierbogen bei geringen Geschwindigkeiten und bei kurzfristigen Maschinenstopp hat darüber hinaus zur Folge, daß sich die Papierbogen um die Greiferleisten der Auslegerketten herum aufwickeln können. Unter mühevoller, zeitraubender manueller Arbeit des Bedienenden müssen die aufgewickelten Papierbogen entfernt werden. Werden sie nicht entfernt, laufen sie mit der Greiferkette weiter um und können Maschinenschäden verursachen. Insbesondere bei so kritischen Umlenkstellen ist es besonders wichtig, möglichst den gesamten Bogenführungsbereich, aber zumindest den kritischen Teil in der Bogenführung sicher zu gestalten. Mit bisher bekannten Saug- bzw. Blasleisten in Auslegertrommelbereich sind lediglich ausschnittsweise Bereiche sicher führbar. Bekannte Saug- bzw. Blaskästen zur Bogenführung mit optimal verlaufendem Saug- bzw. Blasluftanschluß möglichst zentral und großflächig über die gesamten Saug- bzw. Blasbereich hinweg sind aufgrund der räumlichen Enge insbesondere im Bereich der Auslegetrommel nicht ohne weiteres einsetzbar . Saug- bzw. Blaskästen mit schmal gebauten Saugkastenbereich und mit aufgrund der räumlichen Enge ungünstig angeordneten, einfachen Saugstutzen bzw. Blasstutzen ermöglichen aufgrund der hohen Strömungsverluste keine gesicherte Bogenführung über den gesamten Saugkasten bzw. Blaskastenbereich.It is known to form subareas of sheet-guiding surfaces for safe sheet guiding as top surfaces of blow or suction boxes provided with through openings; see for example EP-A-0 495 320. In particular in the curvature areas of the delivery drum of a chain delivery or the preceding printing cylinder of the last printing unit, printed paper sheets experience very strong deflections. It can be observed that the paper sheets in their rear sheet area easily leave their sheet-guiding surface due to the extreme curvatures. Damage to the printed image and the paper sheet cannot be ruled out. At low conveying speeds it can be observed that the trailing edge of the sheet in the area of the delivery drum, in which the paper sheet is taken over with its front edge by the delivery drum and into which the front edge is then passed under the rear sheet area with a change of direction, literally folds in the direction of the axis of the delivery drum and can be damaged on elements of the delivery drum. When the machine is stopped for a short time, the paper sheets can tip into the center region of the delivery drum in the known design of a suction box. The collapse of the paper sheets at low speeds and at short-term machine stops also has the consequence that the paper sheets can wind up around the gripper bars of the delivery chains. The rolled-up sheets of paper have to be laborious, time-consuming manual work by the operator be removed. If they are not removed, they will continue to rotate with the gripper chain and can damage the machine. With such critical deflection points in particular, it is particularly important to make the entire sheet guiding area as safe as possible, but at least the critical part in the sheet guiding. With previously known suction or blow strips in the boom drum area, only sections of areas can be safely guided. Known suction or blowing boxes for guiding sheets with an optimally running suction or blowing air connection, as centrally as possible and over a large area over the entire suction or blowing area, are not readily usable due to the spatial confinement, particularly in the area of the delivery drum. Suction and blow boxes with a narrow suction box area and with simple suction or blow nozzles, which are unfavorably arranged due to the spatial confinement, do not allow a secure bend over the entire suction box or blow box area due to the high flow losses.

Der Erfindung liegt demnach das Problem zugrunde, eine Druckmaschine mit einer Bogenführungsfläche, die zumindest in einem Teilbereich die mit Durchgangsöffnungen versehene Deckfläche eines Blas- bzw. Saugkastens ist, derart zu gestalten, daß eine sichere Bogenführung über die gesamte Deckfläche des Blas- bzw. Saugkastens möglich ist.The invention is therefore based on the problem of designing a printing press with a sheet guiding surface which, at least in a partial area, is the top surface of a blower or suction box provided with through openings, in such a way that reliable sheet guiding over the entire top surface of the blower or suction box is possible.

Erfindungsgemäß gelöst wird das Problem durch die Merkmale von Anspruch 1. Das Strömungswiderstandsprofil in Abhängigkeit vom Abstand von Blas- bzw. Saugstutzen, wobei der Strömungswiderstand mit zunehmendem Abstand vom Blas- bzw. Saugkasten abnimmt, ermöglicht eine Vergleichmäßigung der Strömungsbedingungen in Bereich der Deckfläche über den gesamten Saug- bzw. Blaskasten.The problem is solved according to the invention by the features of claim 1. The flow resistance profile as a function of the distance from the blowing or suction nozzle, the flow resistance decreasing with increasing distance from the blowing or suction box, enables the flow conditions in the area of the cover surface to be made more uniform entire suction or blow box.

Somit ist eine gleichmäßige Bogenführung über die gesamte Deckfläche des Saug- bzw. Blaskastens möglich. Auch schmale Blaskästen bzw. Saugkästen mit extrem dezentraler Anschlußöffnung für die Saugluft- bzw. Blasluftquelle können somit zur sicheren Bogenführung eingesetzt werden.This enables uniform sheet guidance over the entire top surface of the suction or blow box. Also Narrow blow boxes or suction boxes with an extremely decentralized connection opening for the suction air or blow air source can thus be used for safe sheet guidance.

Besonders vorteilhaft und einfach zu verwirklichen ist die Ausgestaltung eines solchen Strömungswiderstandsprofil gemäß den Merkmalen von Anspruch 3. Besonders einfache, kostengünstige und leicht in ihren Strömungsverhalten zu beschreibende Widerstandskörper sind durch die Ausgestaltung als Leitbleche gemäß den Merkmalen von Anspruch 4 möglich. Die Merkmale der Ansprüche 5, 6 und 7 ermöglichen eine besonders einfache, kostengünstige gut einstellbare Ausgestaltung des Strömungsprofils zur Vergleichmäßigung des Strömungsverhaltens in der Deckfläche des Blas- bzw. Saugkastens. Besonders vorteilhaft ist die Verwendung eines solchen Saugkastens im Bereich der Auslegetrommel und die Verwendung eines solchen Blaskastens in Umlenkbereich am Druckzylinder. Beides zusammen ermöglicht eine sichere Bogenführung über den gesamten kritischen s-förmigen Umlenkbereich von Druckzylinder und Auslegetrommel hinweg.The design of such a flow resistance profile according to the features of claim 3 is particularly advantageous and simple to implement. Particularly simple, inexpensive and easily described in their flow behavior resistance bodies are possible through the design as baffles according to the features of claim 4. The features of claims 5, 6 and 7 enable a particularly simple, cost-effective, easily adjustable configuration of the flow profile in order to homogenize the flow behavior in the top surface of the blower or suction box. The use of such a suction box in the region of the delivery drum and the use of such a blow box in the deflection area on the pressure cylinder is particularly advantageous. Both together enable safe sheet guidance over the entire critical S-shaped deflection area of the printing cylinder and delivery drum.

Die Erfindung wird in folgenden anhand von in den Figuren 1 bis 8 dargestellten Ausführungsbeispielen näher erläutert.The invention is explained in more detail below with reference to exemplary embodiments shown in FIGS. 1 to 8.

Fig. 1 zeigt den Auslegebereich einer Bogenoffsetrotationsdruckmaschine, bei der in bekannter Weise Papierbogen vom Druckzylinder 1 des letzten Druckwerks mit Hilfe von an umlaufenden Ketten 3 befestigten Greiferleisten 4 um Kettenräder einer Auslegerantriebswelle 2 herum über eine bogenführende Fläche eines Bogenleitblechs 25 bis über einen Auslagestapel 5 transportiert und auf diesem abgelegt werden. Ein Bogen 26, der von einer Greiferleiste 4 übernommen worden ist, folgt dabei zunächst der Krümmung des Druckzylinders 1 und wird dann mittels Saugluft, die über den Saugstutzen 7, den Saugkasten 6 und die in Fig. 8 dargestellten Durchgangsöffnungen 9 in einem die Deckfläche 8 bildenden Deckblech 8' des Saugkastens 6 auf die von der Auslegerantriebswelle 2 wegweisende Seite des Bogens 26 wirkt, auf die Deckfläche 8 gezogen. Die Deckfläche 8 ist dabei im wesentlichen konzentrisch zur Auslegerantriebswelle 2. Mit Hilfe eines Blasrohres 10 wird die Bogenhinterkante unmittelbar im Bereich der Bogenübergabe vom Druckzylinder 1 an die Auslegetrommel 2' mit Hilfe von Blasluft von der Auslegetrommel 2' nach außen gedrückt, so daß die Bogenhinterkante des Bogens 26 auch nach Bogenübergabe zunächst am Druckzylinder 1 anliegt. Der Bogen 26 wird dann in kleinem Radius vom Druckzylinder 1 abgeschält, um direkt von der Deckfläche 8 des Saugkastens 6 weiter geführt zu werden. Im Saugkasten 6 sind, wie in Fig. 4 dargestellt ist, vom Deckblech 8' nach innen reichende Leitbleche 27, 28, 29, 30, 31, 32, 33 befestigt. Die Leitbleche wirken als Strömungswiderstände für die Saugluftströmung, wobei sie derart gestaltet sind, daß der jeweilige Strömungswiderstand der Leitbleche mit zunehmendem Abstand der einzelnen Leitbleche vom Saugstutzen 7 reduziert wird. Hierdurch ist eine gleichmäßige Beaufschlagung des Bogens nahezu über das gesamte Deckblech 8' des Saugkastens 6 mit Saugluft gewährleistet.Fig. 1 shows the delivery area of a sheet-fed offset printing press, in which paper sheets are transported in a known manner from the printing cylinder 1 of the last printing unit with the aid of gripper bars 4 attached to revolving chains 3 around sprockets of a delivery drive shaft 2 over a sheet-guiding surface of a sheet guide plate 25 to a delivery stack 5 and stored on it. A sheet 26, which has been taken over by a gripper bar 4, first follows the curvature of the pressure cylinder 1 and is then by means of suction air, which over the Suction nozzle 7, the suction box 6 and the through openings 9 shown in FIG. 8 in a cover plate 8 ′ of the suction box 6 forming the cover surface 8 act on the side of the sheet 26 pointing away from the boom drive shaft 2, drawn onto the cover surface 8. The top surface 8 is essentially concentric with the delivery drive shaft 2. With the help of a blow pipe 10, the trailing edge of the sheet is pressed directly in the area of the sheet transfer from the printing cylinder 1 to the delivery drum 2 'with the aid of blown air from the delivery drum 2', so that the trailing edge of the sheet of the sheet 26 initially abuts the impression cylinder 1 even after the sheet has been handed over. The sheet 26 is then peeled off in a small radius by the pressure cylinder 1 in order to be guided directly from the top surface 8 of the suction box 6. In the suction box 6, as shown in FIG. 4, guide plates 27, 28, 29, 30, 31, 32, 33 extending from the cover plate 8 'inward are fastened. The baffles act as flow resistances for the suction air flow, wherein they are designed such that the respective flow resistance of the baffles is reduced with increasing distance of the individual baffles from the suction nozzle 7. This ensures uniform application of suction air to the sheet almost over the entire cover plate 8 'of the suction box 6.

Wie in Fig. 2 am Beispiel eines Saugkastens 11 mit nicht gekrümmter, sondern mit ebener bogenführender Deckfläche 13 dargestellt ist, kann der Strömungswiderstand der Leitbleche mit zunehmendem Abstand vom Saugstutzen 12 dabei in verschiedener Weise erreicht werden. In Fig. 2a sind die Leitbleche 14, 15, 16, 17 in unterschiedlichen Längen ausgeführt, so daß das dem Saugstutzen 12 am nächsten liegende Leitblech 14 am längsten ist. Das Leitblech 15 ist etwas kürzer gewählt, das Leitblech 16 noch etwas kürzer und das Leitblech 17 ist das kürzeste Leitblech. In Fig. 2b sind die Abstände x zwischen zwei benachbarten Leitblechen mit zunehmendem Abstand vom Saugstutzen 12 vergrößert. Somit ist der Abstand zwischen dem Leitblech 14' und 15' der kleinste Abstand; der Abstand zwischen den Leitblechen 16' und 17' ist der größte Abstand. In Fig. 2c ist der Winkel α zwischen Leitblech und Deckfläche 13 mit zunehmendem Abstand vom Saugstutzen 12 vergrößert. Somit ist der Winkel α1 des Leitblechs 14'' der kleinste Winkel, der Winkel αn des Leitblechs 17'' der größte Winkel. Der Anströmwinkel β als der Winkel zwischen Leitblech und Anströmrichtung verhält sich genau umgekehrt. Er ist bei Leitblech 14'' am größten und bei Leitblech 17'' am kleinsten.As is shown in FIG. 2 using the example of a suction box 11 with a curved top surface 13 which is not curved, but with a flat arc-guiding cover surface 13, the flow resistance of the guide plates can be achieved in various ways with increasing distance from the suction nozzle 12. In Fig. 2a, the baffles 14, 15, 16, 17 are made in different lengths, so that the baffle 14 closest to the suction nozzle 12 is the longest. The baffle 15 is chosen to be somewhat shorter, the baffle 16 is somewhat shorter and the baffle 17 is the shortest baffle. In Fig. 2b the distances x between two adjacent baffles are included increasing distance from the suction nozzle 12 increases. Thus, the distance between the guide plate 14 'and 15' is the smallest distance; the distance between the guide plates 16 'and 17' is the greatest distance. In Fig. 2c, the angle α between the guide plate and the top surface 13 is increased with increasing distance from the suction nozzle 12. Thus, the angle α 1 of the guide plate 14 ″ is the smallest angle, the angle α n of the guide plate 17 ″ is the largest angle. The inflow angle β as the angle between the guide plate and the inflow direction is exactly the opposite. It is the largest with the 14 '' baffle and the smallest with the 17 '' baffle.

Sowohl beim Saugkasten mit gerader Deckfläche 13, als auch bei einem Saugkasten mit gekrümmter Deckfläche 8 ist es sinnvoll, insbesondere bei schmal gebauten Saugkästen mit nahezu punktueller Sauglufteinleitung mehrere der in Fig. 2 dargestellten Maßnahmen anzuwenden. Ein Saugkasten 11 mit gerader Deckfläche 13 gemäß Fig. 2 kann zur besseren Bogenführung auch im Bereich des Bogenleitblechs 25 des Auslegers, aber auch im Bereich das Anlegers zur besseren Bogenführung sinnvoll eingesetzt werden.Both with the suction box with a straight cover surface 13 and with a suction box with a curved cover surface 8, it makes sense to use several of the measures shown in FIG. 2, in particular in the case of narrowly constructed suction boxes with almost punctiform suction air introduction. A suction box 11 with a straight cover surface 13 according to FIG. 2 can also be usefully used for better sheet guidance in the area of the sheet guide plate 25 of the delivery, but also in the area of the feeder for better sheet guidance.

Bei zentraler punktueller Sauglufteinleitung in einen schmal gebauten Saugkasten ist es auch möglich, wie in Fig. 3 dargestellt ist, dem Einlaß des Saugstutzens 18 in den Saugkasten 19 direkt gegenüber ein Stirnblech 20 zu befestigen und von diesem beidseitig in und gegen Bogenförderrichtung verteilt die Leitbleche 21, 22, 23, 24 zu befestigen. Auch hier ist das Strömungswiderstandsprofil mittels der Leitbleche so ausgelegt, daß das dem Saugstutzen 18 nächstgelegene Leitblech 21 den größten Strömungswiderstand besitzt und die weiter entfernt liegenden Leitbleche mit zunehmendem Abstand vom Saugstutzen einen geringeren Strömungswiderstand besitzen.In the case of central punctual introduction of suction air into a narrow suction box, it is also possible, as shown in FIG. 3, to fasten the inlet of the suction nozzle 18 into the suction box 19 directly opposite an end plate 20 and distribute the guide plates 21 on both sides in and against the sheet conveying direction , 22, 23, 24 to attach. Here, too, the flow resistance profile is designed by means of the baffles so that the baffle plate 21 closest to the suction nozzle 18 has the greatest flow resistance and the farther away baffles have a lower flow resistance with increasing distance from the suction nozzle.

In den Fig. 5 und 6 sind die Leitbleche des Saugkastens 11 mittels eines innerhalb desselben angeordneten gestanzten Blechs erzeugt, wobei in das Blech gestanzte Laschen 34 jeweils in Richtung auf das Deckblech 8' weisen und an dessen Innenseite anliegen. Die Laschen 34 stellen dabei die Leitbleche dar.5 and 6, the baffles of the suction box 11 are produced by means of a stamped sheet metal arranged inside the same, wherein tabs 34 punched into the sheet metal each point in the direction of the cover sheet 8 'and bear against the inside thereof. The tabs 34 represent the baffles.

Wie in Fig. 7 dargestellt ist, ist es auch denkbar, innerhalb des zwischen den Kettenrädern der Auslegerantriebswelle 2 gebildeten zylindrischen Raums einen über den Bogenführungsbereich reichenden, konzentrisch zur Auslegerantriebswelle 2 gebogenen Blaskasten 38 mit konzentrischer mit Durchgangsöffnungen 9 versehener Deckfläche 41 zu befestigen. Zur gleichmäßigen Druckverteilung im Blaskasten 38 sind von seiten der Deckfläche 41 her in den Blaskasten reichende Leitbleche befestigt, die so gestaltet sind, daß sie jeweils mit zunehmendem Abstand vom Einlaß des Blasstutzens 39 einen abfallenden Strömungswiderstand aufweisen. Der vom Druckzylinder 1 und um die Auslegerantriebswelle 2 geförderte Bogen wird somit nahezu über den gesamten Führungsbereich gleichmäßig mit radial nach außen strömender Blasluft beaufschlagt und so sicher zwischen Bogenführungsblech 35 und Auslegerantriebswelle 2 geführt.As shown in FIG. 7, it is also conceivable to fasten within the cylindrical space formed between the chain wheels of the cantilever drive shaft 2 a blow box 38, which extends over the arc guide area and is curved concentrically to the cantilever drive shaft 2, with a concentric cover surface 41 provided with through openings 9. For uniform pressure distribution in the blow box 38, baffles extending from the top surface 41 are fastened in the blow box, which are designed so that they have a decreasing flow resistance with increasing distance from the inlet of the blow nozzle 39. The sheet conveyed by the printing cylinder 1 and around the delivery drive shaft 2 is thus acted upon uniformly with blowing air flowing radially outwards almost over the entire guide area and thus reliably guided between the sheet guide plate 35 and the delivery drive shaft 2.

Zur Verbesserung der Bogenführung ist es auch denkbar, einen Blaskasten 36 mit Blasstutzen 37 und mit zum Druckzylinder 1 weisender mit Durchgangsöffnungen 9 versehenen, konzentrisch zum Druckzylinder 1 gekrümmten Deckfläche 40 konzentrisch zum Druckzylinder anzuordnen. Der Blaskasten 36 kann dabei eine analoge Struktur zum Saugkasten 19 von Fig. 3 mit bei zunehmendem Abstand vom Blasstutzen 37 abnehmendem Strömungswiderstand erhalten. Hierdurch ist es möglich, bereits im Bereich des Druckzylinders nach Bedrucken des Bogens diesen über nahezu den gesamten Führungsbereich des Druckzylinders 1 gleichmäßig mit radial zur Druckzylinderachse weisender Blasluft zu beaufschlagen und somit an die Druckzylindermantelfläche sicher anzulegen.In order to improve the sheet guidance, it is also conceivable to arrange a blow box 36 with a blow nozzle 37 and with a cover surface 40 facing the printing cylinder 1 and provided with through openings 9 and curved concentrically to the printing cylinder 1 concentrically to the printing cylinder. The blow box 36 can have an analogous structure to the suction box 19 of FIG. 3 with a decreasing flow resistance with increasing distance from the blow nozzle 37. This makes it possible, even in the area of the impression cylinder after the sheet has been printed, to uniformly radially over almost the entire guide area of the impression cylinder 1 Blowing air pointing to the pressure cylinder axis and thus securely contacting the pressure cylinder surface.

Durch Kombination eines solchen Blaskastens 36 am Druckzylinder 1 mit beispielsweise einem Blaskasten 38 oder einem Saugkasten 19, 6 oder 11 im Bereich der Auslegetrommel 2' kann ein Bogen somit sicher über den kritischen Krümmungsbereich des Druckzylinders 1, die Übergabestelle zwischen Druckzylinder 1 und Auslegetrommel 2' mit dem Wechsel in der Krümmung der Bogenführung und über den gesamten Bogenführungsbereich der Auslegetrommel 2' geführt werden.By combining such a blow box 36 on the printing cylinder 1 with, for example, a blow box 38 or a suction box 19, 6 or 11 in the area of the delivery drum 2 ', a sheet can thus be safely over the critical area of curvature of the printing cylinder 1, the transfer point between the printing cylinder 1 and delivery drum 2' with the change in the curvature of the sheet guide and over the entire sheet guide area of the delivery drum 2 '.
