Description

Die Erfindung betrifft fliegend gelagerte Druckwerkzylinder einer Rotationsdruckmaschine, die gegeneinander anstellbar sind.The invention relates to overhung printing cylinder one Rotary printing machine that can be adjusted against each other.

Die ältere Anmeldung DE 195 15 459.2 zeigt ein Druckwerk einer Rotationsdruckmaschine mit fliegend gelagerten Druckwerkzylindern. In diesem Falle sind ein Gegendruckzylinder, ein Übertragungszylinder und ein Formzylinder eines Offsetdruckwerks fliegend in einer Seitenwand gelagert. Soweit die Lagerungen und die Zapfen der Druckwerkzylinder nicht sehr stabil ausgeführt sind, verbiegen sich die Zapfen, wenn die Zylinder gegeneinander angestellt werden. Auch wird das Lagerspiel herausgedrückt. Die Zylinderkörper liegen dann nicht parallel aneinander an, wie schematisch in Figur 2 gezeigt. Dadurch ist die Linienkraft in der Berührungszone der Zylinderkörper über deren Breite nicht konstant. Dies kann sich nachteilig auf die Druckqualität der herzustellenden Druckerzeugnisse auswirken.The older application DE 195 15 459.2 shows a printing unit Rotary printing machine with overhung printing unit cylinders. In this case are an impression cylinder, a transfer cylinder and a forme cylinder Offset printing unit overhung in a side wall. As far as the bearings and the pins of the printing unit cylinders are not very stable, they bend the pins when the cylinders are placed against each other. That too will Bearing play pushed out. The cylinder bodies are then not parallel to each other as shown schematically in Figure 2. This makes the line force in the Contact zone of the cylinder body is not constant across its width. This can be adversely affect the print quality of the printed products to be produced.

Die US-A-4 991 503 zeigt ein Tiefdruckwerk mit zwei fliegend gelagerten Druckwerkzylindern. Der Zapfen eines dieser Zylinder ist in zwei Ebenen in verstellbaren Platten gelagert, um den Winkel zwischen den Achsen der Zylinder zu variieren und diese parallel zu stellen.US-A-4 991 503 shows a gravure printing unit with two cantilevered printing unit cylinders. The cone one of these cylinders is adjustable in two levels Stored at the angle between the plates Vary the axes of the cylinders and place them in parallel.

Der Erfindung liegt die Aufgabe zugrunde, Mittel zu schaffen, die bei den fliegend gelagerten, gegeneinander angestellten Druckwerkzylindern eine möglichst gleichmäßige Linienkraft über die Breite der Zylinderkörper sicherstellen.The invention has for its object to provide means that the flying stored, opposed printing unit cylinders as possible Ensure even line force across the width of the cylinder body.

Figur 1 zeigt den Aufbau eines Druckwerkzylinders mit einem Zylinderkörper, nachfolgend als Zylinder 1 bezeichnet, und dem Zapfen in Form der im Schnitt gezeigten und nachfolgend beschriebenen Spindeleinheit. Der Zylinder 1 kann beispielsweise ein Form- oder Übertragungszylinder eines Druckwerkes sein. Er ist topfförmig ausgebildet und mit seinem Boden am Spindelkopf 2 der Spindel 3 befestigt. Vorteilhaft ist die Befestigung mit Schrauben vorgesehen, und die Aufnahme erfolgt spielfrei mittels Kegelsitz. Die Spindel 3 ist mit hoher axialer und radialer Steifigkeit mittels Wälzlagern 4, 5 in einem Tragrohr 6 gelagert. Auf einem verlängerten Zapfen der Spindel 3, der zusätzlich durch das Lager 32 abgestützt wird, ist ein Motor 7, vorteilhaft ein sogenannter Bausatzmotor, aufgesetzt, der sich ebenfalls im Tragrohr 6 abstützt. Dadurch ist eine steife, spielfreie Verbindung des Motors 7 mit dem Zylinder 1 gewährleistet. Das Tragrohr 6 ist in Gleitlagern 8, 9 in der Seitenwand 11 sowie einer Stützwand 12 gelagert. Dabei schließt im Ausführungsbeispiel das Tragrohr 6 mit einer Hülse 10 ab, die im Lager 9 aufgenommen wird. Die zweite Lagerung in der Stützwand 12 gibt dem Tragrohr 6 einen besonders stabilen Halt. Sie kann beispielsweise als eine mit Abstandsstützen an die Seitenwand 11 angeschraubte Platte oder als an die Seitenwand 11 angeschraubte Brücke ausgebildet sein. Das Tragrohr 6 ist in den Gleitlagern 8, 9 drehbar, wodurch weiter unten beschriebene Anstellbewegungen des Zylinders 1 ermöglicht werden. Die Spindel 3 ist hierzu samt dem Zylinder 1 exzentrisch mit einer Exzentrizität zur Drehachse des Tragrohres 6 angeordnet. Im Ausführungsbeispiel ist die Bohrung des Tragrohres 6, in der die Spindel 3 gelagert ist, exzentrisch zu seinem Außendurchmesser gebohrt, der den Lagersitz für die Aufnahme im Gleitlager 8 trägt. Entsprechend ist auch der Sitz für das Lager 32 in der Hülse 10 exzentrisch zum Lagersitz für das Gleitlager 9 ausgeführt.FIG. 1 shows the structure of a printing couple cylinder with a cylinder body, hereinafter referred to as cylinder 1, and the pin in the form of in section shown and described below spindle unit. The cylinder 1 can for example, a form or transfer cylinder of a printing unit. He is pot-shaped and with its bottom on the spindle head 2 of the spindle 3 attached. The fastening with screws is advantageously provided, and the Admission takes place without play using a conical seat. The spindle 3 is of high axial and radial rigidity by means of roller bearings 4, 5 in a support tube 6. On one elongated pin of the spindle 3, which is additionally supported by the bearing 32 is, a motor 7, advantageously a so-called kit motor, is placed on the also supported in the support tube 6. This creates a rigid, play-free connection of the Motor 7 with the cylinder 1 guaranteed. The support tube 6 is in plain bearings 8, 9 in the side wall 11 and a support wall 12 mounted. It closes in Embodiment from the support tube 6 with a sleeve 10, which in the bearing 9th is recorded. The second bearing in the support wall 12 gives the support tube 6 a particularly stable hold. For example, it can be used as one with spacers plate screwed to the side wall 11 or as to the side wall 11 screwed bridge be formed. The support tube 6 is in the slide bearings 8, 9 rotatable, whereby adjusting movements of the cylinder 1 described below be made possible. For this purpose, the spindle 3 together with the cylinder 1 is eccentric an eccentricity to the axis of rotation of the support tube 6 is arranged. in the The embodiment is the bore of the support tube 6 in which the spindle 3 is mounted is drilled eccentrically to its outer diameter, which is the bearing seat for the Recording in the slide bearing 8 carries. Accordingly, the seat for the bearing 32 in the sleeve 10 eccentric to the bearing seat for the plain bearing 9.

Der zur Antriebssteuerung erforderliche Drehgeber 13 ist auf der Spindel 3 befestigt und am Hebel 14 abgestützt, der wiederum an der Hülse 10 befestigt ist. Die Spindel 3 schließt mit einer Zwei-Wege-Einführung 15 ab, über die beispielsweise ein flüssiges Medium für eventuelle Druckprozeßsteuerungen, wie eine Kühlung, in den Zylinder 1 ein- und aus diesem ausgeführt werden kann. The encoder 13 required for drive control is attached to the spindle 3 and supported on the lever 14, which in turn is attached to the sleeve 10. The spindle 3 concludes with a two-way introduction 15, via which, for example liquid medium for possible printing process controls, such as cooling, in the Cylinder 1 on and can be run from this.

Figur 2 zeigt, wie sich zwei gegeneinander angestellte Druckwerkzylinder ausbiegen, wenn hiergegen keine Vorkehrungen getroffen werden. Als Zylinderkörper kommen hier ein Formzylinder 41 und ein Übertragungszylinder 42 zur Anwendung, die an Spindeleinheiten 33, 34 befestigt sind. Die Spindeleinheiten 33, 34 haben im wesentlichen den in Figur 1 gezeigten Aufbau und verkörpern also die Zapfen der Druckwerkzylinder. Auch bei den noch folgenden Ausführungsbeispielen kommen als Zapfen von Druckwerkzylindern derartige Spindeleinheiten zur Anwendung. Die Erfindung ist aber selbstverständlich auch bei Druckwerkzylindern mit einfachen, direkt bzw. mittels Exzenterbuchsen in der Seitenwand gelagerten Zylinderzapfen anwendbar, wobei diese z.B. auch zusammen mit dem Zylinderkörper aus einem Teil hergestellt sein können. Der Formzylinder 41 und der Übertragungszylinder 42 sind auf eine gegenüber Figur 1 andere Weise an den Spindeleinheiten 33, 34 befestigt, was jedoch für die weiteren Darlegungen keine Bedeutung hat.FIG. 2 shows how two printing unit cylinders, which are positioned against one another, bend, if no precautions are taken against this. Coming as a cylinder body here a forme cylinder 41 and a transfer cylinder 42 for use on Spindle units 33, 34 are attached. The spindle units 33, 34 have essentially the structure shown in Figure 1 and thus embody the pins of Printing cylinder. Also come with the following examples spindle units of this type are used as journals of printing unit cylinders. The However, the invention is of course also for printing unit cylinders with simple, cylinder journals mounted directly in the side wall or by means of eccentric bushings applicable, e.g. also together with the cylinder body from one part can be produced. The forme cylinder 41 and the transfer cylinder 42 are attached to the spindle units 33, 34 in a different way from FIG. 1, however, this has no meaning for the further explanations.

Die Spindeleinheiten 33, 34 sind in zwei Ebenen gelagert, ausgeführt durch die Wände 39, 40. Die zweite Wand 40 kann beispielsweise als an die Wand 39 angeschraubte Brücke, als Teil einer gemeinsamen Kastenwand oder in Form eines anderweitigen Gestellteils ausgebildet sein. Die Spindeleinheiten 33, 34 sind mittels Gleitlagern 35 bis 38 in den Wänden 39, 40 gelagert. Beim Anstellen des Formzylinders 41 und des Übertragungszylinders 42 gegeneinander biegen sich die Spindeln der Spindeleinheiten 33, 34 unter der Druckbelastung, die sich als Linienkraft in der Berührungszone dieser Zylinder 41, 42 äußert, durch. Außerdem wird das Lagerspiel aus den Gleitlagern 35 bis 38 durch die Kraftwirkung herausgedrückt. Als Folge stellen sich der Formzylinder 41 und der Übertragungszylinder 42 schräg und beide nehmen, übertrieben dargestellt, die in Figur 2 gezeigten Lagen ein. Dadurch wird, wie eingangs schon angedeutet, in der Berührungszone des Formzylinders 41 und des Übertragungszylinders 42 über deren Breite keine konstante Linienkraft erzeugt. Eine möglichst konstante Linienkraft ist jedoch zur Erzielung einer guten Druckqualität erforderlich. Abweichungen stören den Druckprozeß, hier die Übergabe des Druckbildes auf den Übertragungszylinder 42. Ebenso ist eine konstante Linienkraft zwischen gegeneinander angestellten Übertragungszylindern erforderlich, hier zwischen dem Übertragungszylinder 42 und einem weiteren nicht gezeigten, die das Druckbild auf beide Seiten einer zwischen ihnen hindurchgeführten Bahn übertragen. Die Bahnkanten 43, 44 sind in Figur 2 schematisch gestrichelt angedeutet. Um eine konstante Druckspannung bzw. Linienkraft über die Breite des Form- und des Übertragungszylinders 41, 42 zu erhalten, sollten diese unter Druckbelastung möglichst parallel zueinander stehen, wie z.B. die in Figur 10 gezeigten Zylinder.The spindle units 33, 34 are supported in two planes, executed by the Walls 39, 40. The second wall 40 can, for example, as against the wall 39 screwed bridge, as part of a common box wall or in the form of a be otherwise formed part of the frame. The spindle units 33, 34 are by means of Plain bearings 35 to 38 stored in the walls 39, 40. When starting the The forme cylinder 41 and the transfer cylinder 42 bend against each other Spindles of the spindle units 33, 34 under the pressure load, which turns out to be Line force expressed in the contact zone of these cylinders 41, 42 by. Moreover the bearing play from the plain bearings 35 to 38 by the force pushed out. As a result, the forme cylinder 41 and the Transfer cylinder 42 obliquely and both take, exaggeratedly shown, in Figure 2 layers shown. As already indicated at the beginning, this means that in the Contact zone of the forme cylinder 41 and the transfer cylinder 42 over whose width does not produce a constant line force. A constant as possible However, line force is required to achieve good print quality. Deviations interfere with the printing process, here the transfer of the print image to the Transfer cylinder 42. There is also a constant line force between mutually positioned transfer cylinders required, here between the Transfer cylinder 42 and another, not shown, which the print image on transmit both sides of a path passed between them. The Web edges 43, 44 are indicated schematically by dashed lines in FIG. 2. To one constant compressive stress or line force across the width of the form and To receive transfer cylinders 41, 42, these should be under pressure are as parallel as possible, e.g. the cylinders shown in Figure 10.

Das nachfolgend beschriebene Ausführungsbeispiel zeigt Mittel, die die Zapfen, sprich die Spindeleinheiten 33, 34, zylinderseitig bewußt aufeinander zu stellen, so daß der Formzylinder 41 und der Übertragungszylinder 42 im nicht gegeneinander angestellten Zustand, d.h. ohne Druckpressung in ihrer Berührungszone, etwa die in Figur 3 gezeigten Stellungen einnehmen würden. Zur Erzielung einer solchen Schiefstellung sind die Gleitlager 35 bis 38 als geregelte hydrostatische Lager ausgebildet. Ein solches hydrostatisches Lager zeigt Figur 4 im Querschnitt. Analog zur Figur 1 ist die Spindel 45 über Wälzlager 46 im Tragrohr 47 abgestützt (Figur 5), das wiederum mittels des hydrostatischen Lagers 48 in der Wand 49 gelagert ist. Dieses Lager 48 besteht beispielsweise aus drei am Umfang verteilten Taschen 50 bis 52, die durch Stege 53 bis 55 voneinander getrennt sind. Die Taschen 50 bis 52 sind außerdem am Umfang durch die Wände 56, 57 zu Ablaufkanälen 58, 59 hin abgedichtet. Mit einer Zahnradpumpe 60 wird Öl über Rückschlagventile 61 bis 63 in die Taschen 50 bis 52 gepreßt. Meßwertaufnehmer 64, 65 ermitteln die Lage der Oberfläche 66 des Druckwerkzylinders. Die Meßwertgeber 64, 65 sind 90° zueinander am Umfang der Oberfläche 66 des Zylinderkörpers angeordnet. Es sind zwei Paare von Meßwertaufnehmern 64, 65 in zwei Ebenen des Zylinderkörpers in dessen Randbereichen vorgesehen. Die Meßwertaufnehmer 64, 65 sind auf eine Regeleinrichtung 67 geschaltet, die ausgangsseitig mit Stelleinrichtungen von Drosselventilen 68 bis 70 verbunden ist. Die Drosselventile 68 bis 70 drosseln Abflußleitungen der Taschen 50 bis 52. Die Regeleinrichtung 67 ermittelt aus den Signalen der Meßwertaufnehmer 64, 65 Abweichungen des Zylinderkörpers von einer vorgegebenen Lage und gibt entsprechende Signale zur Lagekorrektur an die Stelleinrichtungen der Drosselventile 68 bis 70. Damit wird die Abflußmenge des Öles aus den Taschen 50 bis 72 und damit der Druck in diesen Taschen 50 bis 52 bis je nach Belastungsgrad geregelt. In Figur 3 sind alle Gleitlager 35 bis 39 derartig ausgebildet, womit sich die Spindeleinheiten 33, 34 je nach Belastungsgrad einstellen lassen. Sie behalten unabhängig von der Belastung ihre vorgegebene Lage. Eine Lageeinstellung ist bereits auch möglich, wenn nur die Lager einer Ebene, beispielsweise die Gleitlager35 und 37 in der Wand 39 als hydrodynamische Lager ausgebildet sind.The embodiment described below shows means that the pins, say the spindle units 33, 34, consciously on the cylinder side, so that the forme cylinder 41 and the transfer cylinder 42 are not against each other employed state, i.e. without pressure in their contact zone, such as the one in Figure 3 would take positions. To achieve such The bearings 35 to 38 are misaligned as controlled hydrostatic bearings educated. Such a hydrostatic bearing is shown in cross section in FIG. 4. Analogous 1, the spindle 45 is supported in the support tube 47 via roller bearings 46 (FIG. 5), which in turn is mounted in the wall 49 by means of the hydrostatic bearing 48. This bearing 48 consists, for example, of three pockets 50 distributed around the circumference to 52, which are separated from one another by webs 53 to 55. The pockets 50 to 52 are also on the circumference through the walls 56, 57 to drain channels 58, 59 out sealed. With a gear pump 60, oil via check valves 61 to 63 in the pockets 50 to 52 pressed. Transducers 64, 65 determine the position of the Surface 66 of the printing couple cylinder. The sensors 64, 65 are 90 ° arranged to each other on the circumference of the surface 66 of the cylinder body. There are two pairs of sensors 64, 65 in two planes of the cylinder body in the edge areas provided. The transducers 64, 65 are on a Switched control device 67, the output side with actuators from Throttle valves 68 to 70 is connected. Throttle the throttle valves 68 to 70 Drain lines of the pockets 50 to 52. The control device 67 determines from the Signals of the transducers 64, 65 deviations of the cylinder body from a given position and gives appropriate signals to correct the position Actuators of the throttle valves 68 to 70. The outflow of the Oil from pockets 50 to 72 and thus the pressure in these pockets 50 to 52 regulated depending on the degree of exposure. In Figure 3, all plain bearings 35 to 39 are such formed, with which the spindle units 33, 34 depending on the degree of loading let set. Regardless of the load, they keep their default Location. A position setting is already possible if only one of the bearings Level, for example the plain bearings 35 and 37 in the wall 39 as hydrodynamic Bearings are trained.

Die Figuren 6 und 7 zeigen ein hydrostatisches Lager, bei dem gegenüber dem Lager 48 gemäß den Figuren 4 und 5 lediglich die Abdichtung der Taschen anders gestaltet ist. Die Abdichtung der Taschen 71 bis 73 erfolgt hier nicht durch Stege, sondern durch Dichtungen 74 bis 76 mit quadratischem Querschnitt. Der sonstige Aufbau sowie die Regelung des Lagers sind analog zu den Figuren 4 und 5, weshalb auf weitere Erklärungen verzichtet wird.Figures 6 and 7 show a hydrostatic bearing, in which compared Bearing 48 according to Figures 4 and 5 only the sealing of the bags differently is designed. Pockets 71 to 73 are not sealed here by webs, but through seals 74 to 76 with a square cross-section. The other Structure and the control of the camp are analogous to Figures 4 and 5, which is why no further explanations are given.

Figur 8 zeigt die Lagerung zweier Druckwerkzylinder mittels balliger Gleitlager. Eine Spindeleinheit 78 trägt einen Formzylinder 79, während an einer Spindeleinheit 80 ein Übertragungszylinder 81 befestigt ist. Beide Spindeleinheiten 78, 80 sind in der Wand 82 mit Hilfe von balligen Gleitlagern 83, 84 gelagert. Eine weitere Lagerung befindet sich in einer von der Wand 82 beabstandeten Ebene, und zwar werden die balligen Gleitlager 85, 86 von jeweils einer Platte 87, 88 aufgenommen. Diese Platten 87, 88 sind in den Richtungen 89, 90 verstellbar, erlauben also einen radialen Versatz der Gleitlager 85, 86. Durch eine Einstellung der Platten 87, 88 können die Achsen der Spindeleinheiten 78, 80 in der in Figur 8 gezeigten Weise gestellt werden, daß deren Durchbiegung und das Lagerspiel in den Gleitlagern 83 bis 86 im Druckbetrieb derart ausgeglichen werden, daß sich Formzylinder 79 und Übertragungszylinder 81 parallel stellen, so wie dies zum Beispiel bei Figur 10 der Fall ist. Die Verschiebung der Platten 87, 88 wird auch je nach der Lageabweichung des Formzylinders 79 und des Übertragungszylinders 80 von einer Sollage mittels eines Regelkreises ähnlich Figur 4 geregelt, wobei die Regeleinrichtung 67 dann Stelleinheiten zum Verschieben der Platten 87, 88 ansteuert. Statt der Gleitlager 85, 86 können auch die Gleitlager 83, 84 verstellbar ausgeführt und in entsprechend verschiebbaren Platten vorgesehen werden.Figure 8 shows the mounting of two printing unit cylinders by means of spherical plain bearings. A Spindle unit 78 carries a forme cylinder 79, while on a spindle unit 80 a transfer cylinder 81 is attached. Both spindle units 78, 80 are in the Wall 82 mounted with the help of spherical plain bearings 83, 84. Another storage is in a plane spaced from the wall 82, namely the spherical plain bearings 85, 86 each received by a plate 87, 88. This Plates 87, 88 are adjustable in the directions 89, 90, thus allowing one radial offset of the plain bearings 85, 86. By adjusting the plates 87, 88 the axes of the spindle units 78, 80 can be shown in FIG Be put in such a way that their deflection and the bearing play in the Plain bearings 83 to 86 are compensated in the printing operation in such a way that Place forme cylinder 79 and transfer cylinder 81 in parallel, as is the case with Example in Figure 10 is the case. The displacement of the plates 87, 88 also depends on the positional deviation of the forme cylinder 79 and the transfer cylinder 80 from a target position by means of of a control loop similar to FIG. 4, the control device 67 then actuating units for displacing the plates 87, 88. Instead of the Slide bearings 85, 86 can also be made adjustable and in slide bearings 83, 84 accordingly slidable plates are provided.

An den Gehäusen 149 bis 152 greifen gelenkig über Lagerbolzen 153 bis 158 Stelleinheiten, beispielsweise Hydraulikzylinder 159 bis 161, an, die im Druckbetrieb mit definierten Kräften die Formzylinder 133, 134 und Übertragungszylinder 135, 136 zusammenspannen, indem sie hierfür Zugkräfte in den Richtungen 162 bis 167 aufbringen. Die gegeneinander angestellten Form- und Übertragungszylinder 133 bis 136 nehmen dann die in Figur 10 gezeigte parallele Lage zueinander ein. Statt der Hydraulikzylinder 159 bis 161 können auch Pneumatikzylinder oder elektrische bzw. elektromechanische Zylinder Verwendung finden. Die Stelleinheiten 159 bis 161 sind hinsichtlich ihrer Zugkraft zu regeln. Entsprechend der Figur 4 angebrachte Meßwertaufnehmer für die Lage der Form- und Übertragungszylinder 133 bis 136 sind in diesem Fall auf eine Regeleinrichtung geschaltet, die ausgangsseitig die Zugkräfte der Stelleinheiten 159 bis 161 regelt. Im Falle des Einsatzes von Hydraulikzylindern 159 bis 161 wird also der Druck des sie speisenden Hydrauliköles geregelt.In Figures 9 and 10, a device is shown, which at the flying ends the cylinder body attacks the printing unit cylinder. The forme cylinders 133, 134 as well the rubber cylinders 135, 136 carry washers 137 to 140 with bolts at their ends 141 to 144, on which rotatable bearings 145 to 148 housings 149 to 152 are stored. The housings 149 to 152 are articulated over bearing bolts 153 to 158 actuators, for example hydraulic cylinders 159 to 161, which in Printing operation with defined forces the forme cylinders 133, 134 and Tension transfer cylinders 135, 136 together by pulling in Apply directions 162 to 167. The form and against each other Transfer cylinders 133 to 136 then take the parallel shown in Figure 10 Location to each other.
