Abstract

1. To eliminate displacement errors in multicolour printing in sheet-fed rotary printing machines, corrections are carried out by inclination of sheet transport drums. The drive must not be influenced by the inclination. <??>2. A sheet transport drum 1 consisting of support disks 17, 18 and gripper bars 6, 7 is mounted on a drum shaft 16. The support disk 18 is located with a flange 22 on an adjustment eccentric 19. The support disk 17 has on its flange 21 a curved bearing surface 20 about which the drum body can be inclined in relation to the drum shaft 16 by means of the adjustment eccentric 19. Alternatively, the drum body can be coupled to the drive-side bearing flexibly. <??>3. The movements of the drum inclination influence the drive and thus also the transmission ratios of the sheet-guiding cylinders to one another only in such a manner that no displacements which are harmful for the registration arise. <IMAGE>

Description

Die Erfindung betrifft eine Bogentransporttrommel nach dem Oberbegriff des Patenanspruchs 1.The invention relates to a sheet transport drum according to the preamble of patent claim 1.

Eine derartige Vorrichtung ist aus der DE-OS 3 400 652 bekannt.Such a device is known from DE-OS 3 400 652.

Beim Drucken von mehrfarbigen Bildern auf Druckbogen ist dafür zu sorgen, daß alle Teilbilder genau zur Deckung gebracht werden. Die Orientierung in Längs- und Seitenrichtung zum Bild ist dabei über konventionelle Umfangs- bzw. Seitenregistereinrichtungen an Bogendruckmaschinen lösbar. Ein Fehler des Druckbildes durch Schräglage ist aber nicht ohne Weiteres auf diesem Wege korrigierbar. Dazu ist die Technik eingeführt worden, beim Transport durch die Druckmaschine Bogenübergaben vorzusehen, die eine Schrägstellung der Druckbogen vor dem Weitertransport zulassen.When printing multicolored images on printed sheets, make sure that all drawing files are exactly aligned. The orientation in the longitudinal and lateral directions to the image can be solved using conventional peripheral or side register devices on sheet-fed printing machines. However, an error in the printed image due to the inclined position cannot easily be corrected in this way. For this purpose, the technology has been introduced to provide sheet transfers during transport through the printing press, which allow the printing sheets to be tilted prior to further transport.

Eine Vorrichtung dieser Art ist aus der DE-OS 3 400 652 bekannt. In der dort beschriebenen bogenverarbeitenden Druckmaschine soll ein Korrekturzylinder auf seiner Bedienungsseite gegenüber seiner Sollage verstellt werden können. Dadurch wird die Achse des Korrekturzylinders insgesamt gegenüber den Nachbarzylindern schräggestellt. Als Grund für die Lage der Schrägstelleinrichtung auf der Bedienungsseite wird genannt, daß eine bessere Bedienung und ein geringerer mechanischer Aufwand beim Aufbau gewünscht sind.A device of this type is known from DE-OS 3 400 652. In the sheet-processing printing machine described there, a correction cylinder on its operating side should be able to be adjusted relative to its target position. As a result, the axis of the correction cylinder as a whole is inclined relative to the neighboring cylinders. The reason given for the position of the inclined device on the operating side is that better operation and less mechanical effort are required in the construction.

Die Vorrichtung hat den Nachteil, daß sie Auswirkungen auf das Getriebe durch die Schrägstellung nicht vermeidet. Durch die Verschiebung des Zylinders sei es direkt auf der Getriebeseite oder auch auf der gegenüberliegenden Seite, die diesbezügliche Lage ist nicht bekannt, wird immer auch eine Schrägstellung, im gröbsten Falle sogar einer Verschiebung eines Zahnrades im Antriebszug gegenüber den Nachbarnzahnrädern hervorrufen. Damit wird die Problematik der Verbesserung der Bogenübergabe durch eine Verschlechterung der Verhältnisse im Antriebszug kompensiert.The device has the disadvantage that it does not avoid effects on the gearbox due to the inclined position. The displacement of the cylinder, be it directly on the transmission side or also on the opposite side, the position in this regard is not known, will always cause an inclination, in the worst case even a displacement of a gearwheel in the drive train with respect to the neighboring gearwheels. This compensates for the problem of improving sheet transfer by worsening the conditions in the drive train.

In der DE-C1 37 04 314 ist eine Anordnung zur Zahnspieleinstellung zwischen den Antriebszahnrädern von bogentransportierenden Zylindern und Trommeln von Bogenrotationsdruckmaschinen beschrieben. Hier sind auf beiden Seiten zur Lagerung aller genannten Trommeln exzentrisch Lagerbüchsen vorgesehen. Sie werden zur Parallelverschiebung der Trommeln benutzt, um das Zahnspiel im Antrieb einzustellen. Eine Schrägstellung der Trommeln ist nicht vorgesehen und kann ohne Nachteil für die Antriebsverhältnisse nicht durchgeführt werden.DE-C1 37 04 314 describes an arrangement for adjusting tooth play between the drive gear wheels of sheet-transporting cylinders and drums of sheet-fed rotary printing machines. Eccentric bearing bushes are provided on both sides for the storage of all of the drums mentioned. They are used to move the drums in parallel to adjust the tooth play in the drive. An inclination of the drums is not provided and cannot be carried out without disadvantage for the drive conditions.

Ziel der Erfindung ist es, die Antriebsverhältnisse nicht durch Zusatzmaßnahmen im Bereich der Registereinstellung zu verschlechtern.The aim of the invention is not to worsen the drive conditions through additional measures in the area of the register setting.

Der Erfindung liegt daher die Aufgabe zugrunde, in einer Vorrichtung nach dem Oberbegriff des Patentanspruchs 1 Mittel vorzusehen, die eine Veränderung der Antriebsverhältnisse durch ein Schrägstellen einer Bogentransporttrommel verhindern.The invention is therefore based on the object of providing means in a device according to the preamble of patent claim 1 which prevent a change in the drive conditions by inclining a sheet transport drum.

Die Aufgabe wird nach dem Kennzeichen des Patentanspruchs 1 gelöst. Durch die verschiedenen Möglichkeiten zur Entkoppelung der schräggestellten Teile der Bogentransporttrommel gegenüber dem Antriebszahnrad erweitert sich der Anwendungsbereich der Technik der Schrägkorrektur durch Zylinderschrägstellung. Insbesondere vereinfacht sich der gesamte Korrekturablauf. Die größten Auswirkungen hat die Erfindung aber für die Belastung der Lagerung und die Exaktheit der Antriebsverhältnisse. Das Antriebszahnrad und auch die Lagerung des antriebsseitigen Wellenzapfens verbleiben auch bei Schrägstellung in ihrer jeweiligen Position. Je nach Variante der Erfindung kann sogar die gesamte Trommellagerung in ihrer Ursprungsposition verbleiben. Damit erspart man sich aufwendige Lagerungen bzw. Mittel zu deren Führung bei Verschiebungen.The object is achieved according to the characterizing part of patent claim 1. The various possibilities for decoupling the inclined parts of the sheet transport drum with respect to the drive gearwheel expands the field of application of the technology of the inclined correction by tilting the cylinder. In particular, the entire correction process is simplified. However, the invention has the greatest effects on the load on the bearing and the accuracy of the drive conditions. The drive gear and the bearing of the drive-side shaft journal remain in their respective positions even when they are inclined. Depending on the variant of the invention, the entire drum bearing can even remain in its original position. This saves complex bearings and means for guiding them when moving.

Im Prinzip sind damit zwei Lösungsmöglichkeiten für die Entkoppelung der Schrägstellbewegung innerhalb einer Bogentransporttrommel vom Lager bzw. dem Antriebszahnrad der Trommel vorgegeben: Zum einen kann die Welle der Bogentransporttrommel gegenüber dem antriebsseitigen Lager durch axialbewegliche aber radial und in Umfangsrichtung steife Elemente vorgesehen werden. Zum anderen kann auf einer starren Trommelwelle ein schrägstellbarer aber in Umfangsrichtung starr gelagerter Trommelkörper vorgesehen werden.In principle, there are two possible solutions for decoupling the inclined movement within a sheet transport drum from the bearing or the drive gear of the drum: First, the shaft of the sheet transport drum can be provided with axially movable but radially and circumferentially rigid elements relative to the drive-side bearing. On the other hand, an inclined drum body which is rigidly mounted in the circumferential direction can be provided on a rigid drum shaft.

Weitere vorteilhafte Ausgestaltungen werden in den Unteransprüchen in Einzelnen beschrieben.Further advantageous refinements are described in detail in the subclaims.

Die Erfindung wird im Folgenden anhand von zeichnerischen Darstellungen beispielhaft erläutert. Die Veränderung der Lage des Trommelkörpers und seiner Achse ist in den Figuren jeweils strichliert dargestellt.The invention is explained below by way of example with reference to drawings. The change in the position of the drum body and its axis is shown in dashed lines in the figures.

In Figur 1 ist eine Bogentransporttrommel 1 nach der Erfindung dargestellt. Die Bogentransporttrommel 1 besteht im wesentlichen aus einem Antriebszapfen 2 und einem Wellenzapfen 3 mit daran angeflanschten Tragscheiben 4, 5. Zwischen den Tragscheiben 4, 5 sind Greiferbalken 6, 7 zur Anbringung von Greifereinrichtungen für den Bogentransport vorgesehen. Für Antriebs- 2 und Wellenzapfen 3 sind Lagerungen 8, 9 in der Maschinenwand 10 vorgesehen. Auf dem Antriebszapfen 2 ist ein Antriebszahnrad 11 befestigt. Auf der gegenüberliegenden Seite ist an der Lagerung 9 zusätzlich ein Stellexzenter 12 vorgesehen, mit dessen Hilfe die Achse der Bogentransporttrommel 1 verschwenkt werden kann. Durch Drehung des Stellexzenters 12 mit Hilfe eines hier nicht dargestellten Stellantriebs wird die Lage der Achse gegenüber der Normallage um einen Schwenkpunkt S schräggestellt. Dies ist durch die doppelt strichpunktierte Linie dargestellt. Der Schwenkpunkt S liegt auf der Trommelachse am inneren Rand des Antriebszapfens 2. Da durch die Verbindung innerhalb der Bogentransporttrommel 1 auch das Antriebszahnrad 11 schräggestellt werden würde, ist im Übergang zwischen der Tragscheibe 4 auf der Antriebsseite und dem Antriebszapfen 2 eine in geringem Umfang axialbewegliche Entkoppelung vorgesehen. In Drehrichtung und radial ist die Koppelstelle aber so steif ausgelegt, daß keine Bewegung möglich ist.In Figure 1, a sheet transport drum 1 is shown according to the invention. The sheet transport drum 1 essentially consists of a drive pin 2 and a shaft pin 3 with supporting disks 4, 5 flanged thereon. Bearings 8, 9 are provided in the machine wall 10 for drive 2 and shaft journals 3. A drive gear 11 is fastened on the drive pin 2. On the opposite side, a positioning eccentric 12 is additionally provided on the bearing 9, with the aid of which the axis of the sheet transport drum 1 can be pivoted. By rotating the positioning eccentric 12 with the aid of an actuator (not shown here), the position of the axis is inclined relative to the normal position about a pivot point S. This is shown by the double-dashed line. The pivot point S lies on the drum axis at the inner edge of the drive pin 2. Because of the connection within the sheet transport drum 1 that too Drive gear 11 would be inclined, a small amount of axially movable decoupling is provided in the transition between the support plate 4 on the drive side and the drive pin 2. In the direction of rotation and radially, however, the coupling point is designed so rigid that no movement is possible.

Die Gestaltung der Koppelstelle in der Verbindung zwischen Tragscheibe 4 und Antriebszapfen 2 ist in Figur 2 dargestellt. Der Antriebszapfen 2 trägt das Zahnrad 11 und ist in der Lagerung 8 geführt. Auf seinem inneren Ende ist die Tragscheibe 4 aufgesetzt. Sie wird mit Hilfe einer ringförmigen Kupplungsmembran 13 an den Antriebszapfen 2 angeschlossen. Die Kupplungsmembran 13 ist mit je einem gleichmäßig verteilten Satz von Verbindungsschrauben 14 mit der inneren Stirnseite des Antriebszapfens 2 und dem inneren Umfang der Tragscheibe 4 verbunden. Dadurch wird die Tragscheibe 4 mit dem Antriebszapfen 2 bündig gehalten, wobei axiale Bewegungen weitestgehend vermieden werden. Andererseits kann aber eine Biegung um die durch die Kupplungsmembran 13 definierte Verbindung erfolgen.The design of the coupling point in the connection between the support plate 4 and the drive pin 2 is shown in FIG. 2. The drive pin 2 carries the gear 11 and is guided in the bearing 8. The support disk 4 is placed on its inner end. It is connected to the drive pin 2 with the aid of an annular coupling membrane 13. The coupling membrane 13 is connected to the inner end face of the drive pin 2 and the inner circumference of the support disk 4 with a uniformly distributed set of connecting screws 14. As a result, the support disk 4 is held flush with the drive pin 2, axial movements being largely avoided. On the other hand, however, a bend can take place around the connection defined by the coupling membrane 13.

In Figur 3 ist dargestellt, daß eine innere Umfangsfläche 26 der Tragscheibe 4, die einer äußeren Umfangsfläche 15 des Antriebszapfen 2 gegenübersteht, im Querschnitt d.h. in axialer Richtung zur Bogentransporttrommel bogenförmig ausgeführt ist. Die Tragscheibe 4 sitzt also annähernd linienförmig auf der Umfangsfläche 15 des Antriebszapfens 2 auf. Bei Verstellung des Stellexzenters 12 wird der Trommelkörper und damit auch die Tragscheibe 4 gegenüber dem Antriebszapfen 2 schräggestellt. Die Schrägstellung erfolgt in einer festen Ebene, die durch den Stellexzenter 12 vorgegeben wird. Sie wird in etwa senkrecht zur der Verbindungsebene durch die Achsen von mit der Bogentransporttrommel 1 zusammenarbeitenden bogenführenden Zylindern, z.B. Druckzylindern einer Bogenoffsetdruckmaschine, liegen. Damit wird die Kupplungsmembran 13 radial gesehen in ihrem Mittelbereich axial elastisch verformt, wobei die Tragscheibe 4 mit ihrer bogenförmigen inneren Umfangsfläche 26 auf der äußeren Umfangsfläche 15 des Antriebszapfens 2 "abrollt". Da die Schwenkebene statisch ist, läuft die Auslenkung an der Koppelstelle zwischen Antriebszapfen 2 und Tragscheibe 4 entsprechend der Rotationsbewegung relativ zur Bogentransporttrommel um. Die Bewegung ist insgesamt aber sehr klein. Bei einer Exzentrizität von z.B. 5 mm am Stellexzenter 12 ist etwa ein Schwenkweg von 5/100 mm an der Einspannstelle zu erwarten, die leicht durch die Kupplungsmembran 13 aufgenommen werden kann. Die realistischen Schwenkwege sind aber viel kleiner da die Verstellungen im Bereich von 1/10 mm liegen.In FIG. 3 it is shown that an inner circumferential surface 26 of the support disk 4, which faces an outer circumferential surface 15 of the drive pin 2, has an arcuate cross section, ie in the axial direction to the sheet transport drum. The support disk 4 is therefore seated approximately linearly on the peripheral surface 15 of the drive pin 2. When adjusting the positioning eccentric 12, the drum body and thus also the support disk 4 are inclined relative to the drive pin 2. The inclination takes place in a fixed plane, which is predetermined by the positioning eccentric 12. It will lie approximately perpendicular to the connection plane through the axes of sheet-guiding cylinders cooperating with the sheet transport drum 1, for example printing cylinders of a sheet-fed offset printing machine. With that the Coupling diaphragm 13, seen radially in its central region, is axially elastically deformed, the support disk 4 "rolling" with its arcuate inner peripheral surface 26 on the outer peripheral surface 15 of the drive pin 2. Since the swivel plane is static, the deflection at the coupling point between the drive pin 2 and the support disk 4 rotates relative to the sheet transport drum in accordance with the rotational movement. Overall, the movement is very small. With an eccentricity of, for example, 5 mm at the positioning eccentric 12, a swiveling path of 5/100 mm at the clamping point can be expected, which can easily be accommodated by the coupling membrane 13. The realistic swivel paths are much smaller since the adjustments are in the range of 1/10 mm.

In Figur 3 sind die Schwenkbewegung der Tragscheibe 4 und die Biegung der Kupplungsmembran 13 strichliert und übertrieben dargestellt. In Figur 4 ist eine Variante zur Schrägstellung eines Trommelkörpers auf einer durchgehenden Trommelwelle 16 dargestellt. Dazu ist der Trommelkörper mit Tragscheiben 17, 18 an zwei Stellen auf der Trommelwelle 16 gelagert, wobei die Tragscheiben 17, 18 in Umfangsrichtung starr mit der Trommelwelle 16 verbunden sind. Auf der vom Antriebszahnrad 11 abgewendeten Seite ist zwischen der Tragscheibe 18 und der Trommelwelle 16 ein Stellexzenter 19 vorgesehen, mit dessen Hilfe der Trommelkörper gegenüber der Trommelwelle 16 schräggestellt werden kann. Um eine Biegung auf die Trommelwelle 16 durch das Schrägstellen der Tragscheibe 17 zu vermeiden, ist diese mit einer bogenförmig ausgeführten Lagerfläche 20 gegenüber der Trommelwelle 16 versehen. Durch Verschieben der Tragscheibe 18 und Verlagerung ihres Mittelpunkts wird sich die Tragscheibe 17 auf der Antriebsseite auf ihrer bogenförmigen Lagerfläche 20 abwälzen. Damit wird die Bogenübergabe zwar schräggestellt, es werden aber Biegungen an der Trommelwelle 16 vermieden. Die Tragscheiben 17, 18 sind mit Flanschen 21, 22 auf der Trommelwelle 16 aufgesetzt und mit Bolzen 23, 24 an die Trommelwelle 16 in Umfangsrichtung starr angekoppelt. Ein dazu erforderlicher Stellantrieb kann umlaufend an der Tragscheibe 18 oder ortsfest am Maschinengestell 25 mit einem durch die Trommelwelle 16 geführten Koppelgetriebe angeordnet sein.In Figure 3, the pivoting movement of the support plate 4 and the bending of the clutch membrane 13 are shown in broken lines and exaggerated. FIG. 4 shows a variant for the inclination of a drum body on a continuous drum shaft 16. For this purpose, the drum body with support disks 17, 18 is mounted at two points on the drum shaft 16, the support disks 17, 18 being rigidly connected to the drum shaft 16 in the circumferential direction. On the side facing away from the drive gear 11, a setting eccentric 19 is provided between the support disk 18 and the drum shaft 16, with the aid of which the drum body can be inclined relative to the drum shaft 16. In order to avoid a bend on the drum shaft 16 due to the inclination of the support disk 17, it is provided with an arcuate bearing surface 20 opposite the drum shaft 16. By moving the support disk 18 and shifting its center, the support disk 17 will roll on its arcuate bearing surface 20 on the drive side. Thus, the sheet transfer is inclined, but bends on the drum shaft 16 are avoided. The support disks 17, 18 are with flanges 21, 22 on the Mounted drum shaft 16 and rigidly coupled with bolts 23, 24 to the drum shaft 16 in the circumferential direction. An actuator required for this can be arranged circumferentially on the support disk 18 or stationary on the machine frame 25 with a coupling gear guided through the drum shaft 16.

Denkbar ist schließlich noch eine weitere Variante zur Schrägstellung des Trommelkörpers, wobei hier im Übergang zwischen dem Wellenzapfen und der Welle zum Trommelkörper eine Nut angebracht ist, die eine bevorzugte Biegung der Welle an dieser Stelle zuläßt. Damit wird auch hier die Einleitung von Biegungen auf Lagerung und Antriebszahnrad vermieden.Finally, a further variant for the inclination of the drum body is conceivable, a groove being provided here in the transition between the shaft journal and the shaft to the drum body, which groove permits a preferred bending of the shaft at this point. This also prevents the initiation of bends on the bearing and drive gear.
