Description

Die vorliegende Erfindung bezieht sich auf eine Vorrichtung zum Verstellen des Umfangs-und Seitenregisters in einer Rotationsdruckmaschine.The present invention relates to a device for adjusting the circumference and Page register in a rotary printing press.

In einer Rotationsoffsetmaschine steht ein Plattenzylinder in Abrollkontakt mit einem Gummizylinder, der wiederum die Bahn (das zu bedruckende Material) kontaktiert. Im Verlaufe eines Druckdurchgangs muß des öfteren hin und wieder die Position des Plattenzylinders zum Gummizylinder nachgestellt werden. Eine Verstellung kann beispielsweise erforderlich sein, damit das gedruckte Bild mit einem bereits auf der Bahn befindlichen Bild registerhaltig ist. Einstellen des Registers kann seitlich (in Richtung der Zylinderachsen) oder umfänglich (in Rotationsrichtung) erforderlich sein. Eine entsprechende Verstellung kann beispielsweise in einer typischen Farbendruckmaschine mit vier Druckwerken, wobei jedes Druckwerk Punkte in einer speziellen Farbe druckt, erforderlich werden. Die Kombination dieser farbigen Punkte auf dem Papier ergibt ein farbiges Bild. Jeder Satz von farbigen Punkten muß ausgerichtet mit den anderen gedruckt werden, damit ein scharfes farbiges Bild gewonnen wird. Werden die Punkte mit Fehlausrichtung gedruckt, muß das Register der Druckwerke so nachgestellt werden, daß die Druckwerke ihre Punkte in richtiger Passung drucken.In a rotary offset machine, a plate cylinder is in rolling contact with one Rubber cylinder, which in turn contacts the web (the material to be printed). in the The course of a print run must often change the position of the Plate cylinder to be adjusted to the rubber cylinder. An adjustment can For example, it may be necessary to have the printed image with one already on the web located image is in register. The register can be adjusted laterally (in the direction of the Cylinder axes) or circumferentially (in the direction of rotation). A corresponding Adjustment can take place, for example, in a typical color printing machine with four Printing units, each printing unit printing dots in a special color, required become. The combination of these colored dots on paper gives a colored picture. Each set of colored dots must be printed aligned with the others so that a sharp colored image is obtained. If the dots are printed with misalignment, the register of the printing units must be adjusted so that the printing units get their points in print correct fit.

Vorrichtungen zum Einstellen der seitlichen und umfänglichen Positionen des Druckzylinders sind bekannt. Bei einigen dieser Vorrichtungen befinden sich der seitliche Versteller und der umfängliche Versteller auf entgegengesetzten Seiten der Druckmaschine. Da die Versteller auf entgegengesetzten Seiten der Druckmaschine angeordnet sind, fällt es dem Maschinenbediener schwer, wiederholte Verstellungen der Zylinderposition vorzunehmen.Devices for adjusting the lateral and circumferential positions of the printing cylinder are known. Some of these devices have the side adjuster and the Extensive adjusters on opposite sides of the press. Because the adjuster are arranged on opposite sides of the printing press, it falls It is difficult for machine operators to make repeated adjustments to the cylinder position.

Bei anderen Verstellvorrichtungen ist dieses Problem durch Anordnen der seitlichen und umfänglichen Versteller auf der gleichen Seite der Maschine gelöst. Derartige Vorrichtungen sind einfacher zu bedienen und bauen kompakter, sind aber komplex und somit kostspielig. In other adjustment devices this problem is caused by arranging the side and extensive adjuster on the same side of the machine. Such devices are easier to use and build more compact, but are complex and therefore expensive.

Die EP 0 262 298 A2 beschreibt eine Registereinstellvorrichtung zur Verstellung des Seiten- und Umfangregisters in einer Rotationsdruckmaschine, bei der auf einer mit einem Plattenzylinderzapfen drehbar verbundenen Feingewindewelle eine Innengewindehülse angeordnet ist, die drehbar mit einem auf dem Zylinderzapfen angeordneten axial verschiebbaren Antriebszahnrad für den Zylinder verbunden ist. Zum Verstellen des Seitenregisters wird die Feingewindewelle in einer gestellfesten Innengewindebuchse durch einen ersten Antrieb rotiert und verschiebt den Zylinderzapfen in axialer Richtung. Eine Verstellung des Umfangsregisters erfolgt dadurch, daß bei feststehender Feingewindewelle die Hülse rotiert und dadurch zusammen mit dem eine Schrägverzahnung aufweisenden Antriebszahnrad in axialer Richtung verschoben wird, wodurch das Zahnrad und der Zylinderzapfen in Folge eines Eingriffs mit dem feststehenden Gummituchzylinderzahnrad in Umfangsrichtung des Zylinders gedreht werden.EP 0 262 298 A2 describes a register setting device for adjusting the Page and circumference registers in a rotary printing press, on which one with one Plate cylinder journal rotatably connected fine-thread shaft an internal thread sleeve is arranged, which is rotatable with an axially arranged on the cylinder journal slidable drive gear for the cylinder is connected. To adjust the The fine-thread shaft is located in the side register in an internal threaded bushing fixed to the frame a first drive rotates and shifts the cylinder journal in the axial direction. An adjustment of the circumferential register takes place in that when the Fine thread shaft rotates the sleeve and thereby together with the one Drive gear having helical teeth is moved in the axial direction, whereby the gear and the cylinder pin as a result of an engagement with the fixed blanket cylinder gear rotated in the circumferential direction of the cylinder become.

Die DE 44 07 691 A1 beschreibt eine Registerverstellvorrichtung mit einer ein Gewinde aufweisenden Welle, die drehbar mit dem Antriebszapfen eines Plattenzylinders einer Druckmaschine verbunden ist, und bei der eine Umfangsregisterverstellung mit Hilfe einer gestellfesten, die Welle umgreifenden Zwischenhülse sowie einer auf die gestellfeste Zwischenhülse aufgeschraubten weiteren Hülse erfolgt.DE 44 07 691 A1 describes a register adjustment device with a thread having shaft that rotates with the drive pin of a plate cylinder Printing machine is connected, and in which a circumferential register adjustment with the help of a frame-fixed, the shaft around the intermediate sleeve and one on the frame-fixed Intermediate sleeve screwed on further sleeve.

Gemäß der vorliegenden Erfindung werden die Mängel der bekannten Vorrichtungen dadurch beseitigt, daß seitliche und umfängliche Versteller mit einfacher Bauweise auf der gleichen Seite der Maschine vorgesehen sind. Die Bauweise ist einfach, weil eine einzige Präzisionsgewindewelle in zwei verschiedenen Betriebsarten eingesetzt wird: einmal für das Seitenregister und einmal für das Umfangsregister.According to the present invention, the shortcomings of the known devices thereby eliminated that lateral and circumferential adjuster with a simple design on the same side of the machine are provided. The design is simple because of one Precision threaded shaft is used in two different operating modes: one for the Side register and once for the circumferential register.

Gemäß der vorliegenden Erfindung ist eine Buchse mit Innengewinde vorgesehen. Eine Präzisionsgewindewelle ist in der Gewindebuchse angeordnet und steht mit ihr in Eingriff. Die Welle ist mit dem Plattenzylinder so verbunden, daß der Plattenzylinder bei seitlicher Bewegung die Welle seitlich bewegt wird. Die Welle wird durch einen ersten Antrieb gedreht. Gleichermaßen wird die Gewindebuchse durch einen zweiten Antrieb gedreht. According to the present invention, a socket with an internal thread is provided. A Precision threaded shaft is arranged in the threaded bush and engages with it. The shaft is connected to the plate cylinder so that the plate cylinder at the side Movement the shaft is moved sideways. The shaft is powered by a first drive turned. Likewise, the threaded bush is turned by a second drive.

Die Gewindebuchse ist mit dem Plattenzylinder durch ein Getriebe so verbunden, daß der Plattenzylinder bei seitlicher Bewegung der Gewindebuchse rotiert.The threaded bush is connected to the plate cylinder by a gear so that the Plate cylinder rotates when the threaded bushing moves laterally.

Weiter beinhaltet das Getriebe ein Schrägrad, an dem innen eine Nut ausgebildet ist, die mit dem Keil in Eingriff steht. Das Schrägrad ist mit der Gewindebuchse drehbar verbunden. Außerdem steht das Schrägrad außen mit einem an dem Gummizylinder befestigten Zahnrad in Eingriff. Eine seitliche Kraft wird auf das Schrägrad durch die seitliche Bewegung der Gewindebuchse ausgeübt, so daß, wenn die Gewindebuchse sich seitlich bewegt, das Schrägrad seitlich bewegt wird und rotiert (durch das Kämmen mit dem Gummizylinder-Zahnrad), so daß eine Umfangsbewegung des Plattenzylinders bezüglich des Gummizylinders bewirkt wird. The gearbox also includes a bevel, on which a groove is formed on the inside engages with the wedge. The helix can be rotated with the threaded bush connected. In addition, the incline is on the outside of the rubber cylinder attached gear engaged. A lateral force is exerted on the bevel by the lateral movement of the threaded bushing is exerted so that when the threaded bushing turns moved sideways, the degree of inclination is moved sideways and rotates (by combing with the rubber cylinder gear) so that a circumferential movement of the plate cylinder is effected with respect to the rubber cylinder.

Um eine Verstellung des Seitenregisters vorzunehmen, wird die Welle durch den ersten Antrieb gedreht, während die Buchse festgehalten wird. Aufgrund ihrer Gewindeverbindung mit der Gewindebuchse bewegt die rotierende Welle sich seitlich und bewegt den Plattenzylinder seitlich.In order to adjust the side register, the shaft is replaced by the first Drive rotated while holding the bushing. Because of their threaded connection with the threaded bush, the rotating shaft moves laterally and moves the Plate cylinder on the side.

Für eine Verstellung des Umfangsregisters wird die Gewindebuchse durch den zweiten Antrieb gedreht, während die Welle festgehalten wird. Infolge ihrer Gewindeverbindung mit der Welle bewegt die Gewindebuchse sich seitlich, treibt dadurch das Getriebe an und bewirkt, daß der Plattenzylinder umfänglich gedreht wird, wie oben beschrieben.For an adjustment of the circumferential register, the threaded bush is replaced by the second one Drive rotated while holding the shaft. Due to their threaded connection with the shaft moves the threaded bushing sideways, thereby driving the gear and causes the plate cylinder to be rotated circumferentially as described above.

Die Buchse 10 ist innerhalb eines Zahnrads 21 angeordnet und an diesem befestigt. Das Zahnrad 21 steht außen mit einem Ritzel 22 in Eingriff. Das Ritzel 22 ist koaxial an einer Welle 23 befestigt. Das Ritzel 22 ist in der seitlichen Richtung so lang, daß es mit dem Zahnrad 21 über den gesamten Seitenverstellweg des Zahnrads 21 in Eingriff bleibt. Die Welle 23 geht durch die Registerantriebsplatte 17 hindurch. Ein Kegelrad 24 ist koaxial an dem Ende der Welle 23 außerhalb der Registerantriebsplatte platte 17 befestigt. Das Kegelrad 24 steht mit einem zweiten Motor (nicht gezeigt) in Verbindung. Der zweite Motor, das Kegelrad 24, die Welle 23, das Ritzel 22 und das Zahnrad 21 bilden zusammen den Buchsenantrieb der Buchse 10 in der in Fig. 2 dargestellten Ausführungsform der vorliegenden Erfindung.The bushing 10 is arranged within a gearwheel 21 and fastened to it. The Gear 21 is externally engaged with a pinion 22. The pinion 22 is coaxial with one Shaft 23 attached. The pinion 22 is so long in the lateral direction that it with the Gear 21 remains engaged over the entire side adjustment path of the gear 21. The Shaft 23 passes through the register drive plate 17. A bevel gear 24 is on coaxially plate 17 attached to the end of the shaft 23 outside the register drive plate. The bevel gear 24 stands with a second motor (not shown) in connection. The second motor, the bevel gear 24, the Shaft 23, the pinion 22 and the gear 21 together form the bush drive of the bush 10 in the embodiment of the present invention shown in FIG. 2.

Die Buchse 10 ist durch Lager 25, die umfängliches, freies Drehen der Buchse 10 ermöglichen, gelagert. Die Buchse 10 ist aber in ihre Lager 25 so eingepaßt, daß seitliches Verrutschen der Buchse 10 in den Lagern 25 nicht erfolgen kann. Die Lager 25 sind in einer Kragen- oder Ringeinheit 26 angeordnet, die zum Erleichtern der Herstellung aus einem Innenring und einem Außenring 28 besteht. Der Außenring 28 ist mit Schrauben 29 an dem Innenring befestigt. Der Innenring besitzt eine integrale Lippe 30, die so liegt, daß das Lager 25 gegen die Lippe 30 drücken kann. Gleichermaßen besitzt der Außenring 28 eine integrale Lippe 31, die so liegt, daß das Lager 25 gegen die Lippe 31 drücken kann.The bush 10 is through bearing 25, the circumferential, free rotation of the bush 10 allow stored. However, the socket 10 is fitted in its bearing 25 so that lateral The bushing 10 cannot slip in the bearings 25. The bearings 25 are in one Collar or ring unit 26 arranged to facilitate manufacture from a Inner ring and an outer ring 28 there. The outer ring 28 is on with screws 29 attached to the inner ring.

Die Ringenheit 26 ist mit vier Schrauben 33 an einem Schrägrad 32 befestigt. Das Schrägrad 32 steht außen in Eingriff mit dem Schrägrad 8 des Gummizylinders. Ein gerader Keil 34 ist in dem Schrägrad 32 vorgesehen und steht mit diesem in Eingriff. Der gerade Keil 34 ist so angeordnet und an den verstellseitigen Lagerzapfen 2 des Plattenzylinders montiert, daß umfängliches Drehen des Keils 34 unabhängig von dem Plattenzylinder 1 nicht möglich ist. Der gerade Keil 34 beschränkt die Bewegungsfreiheit des Schrägrads 32 und verhindert umfängliches Drehen des Schrägrads 32 bezüglich des Platterzylinders 1.The ring 26 is fastened to a bevel 32 with four screws 33. The slant 32 is externally engaged with the bevel 8 of the blanket cylinder. A straight wedge 34 is provided in the bevel degree 32 and is in engagement therewith. The straight wedge 34 is like this arranged and mounted on the adjustable journal 2 of the plate cylinder that circumferential rotation of the wedge 34 is not possible regardless of the plate cylinder 1. The straight wedge 34 limits the freedom of movement of the bevel 32 and prevents it rotating the bevel 32 circumferentially with respect to the platter cylinder 1.

Ein Stirnrad 35 ist zum Antrieb der Auftragwalze (nicht gezeigt) der Druckmaschine vorgesehen. Der Antrieb des Stirnrads 35 erfolgt durch die Verbindung mit dem bedienerseitigen Lagerzapfen.A spur gear 35 is for driving the application roller (not shown) of the printing press intended. The spur gear 35 is driven by the connection with the operator bearing journal.

In einem ersten Verstellmodus wird das seitliche Register durch Drehen der Welle 9 eingestellt. In dieser Betriebsart wird die Buchse 10 durch den Buchsenantrieb festgehalten. Der Wellenantrieb treibt das Zahnrad 18, und dieses wiederum dreht die Welle 9 entweder im Uhrzeigersinn oder im Gegenuhrzeigersinn. Da die Welle 9 mit den Mutterplatten 14, 15 und der Buchse 10 in Gewindeverbindung steht, wird die Welle 9 seitlich angetrieben, und zwar in einer der Drehrichtung entsprechenden Richtung. Die Welle 9 drückt oder zieht) den Plattenzylinder 1 in seitlicher Richtung durch Kraftübertragung über die Wellenlager 11. Auf diese Weise wird der Plattezylinder 1 seitlich verstellt.In a first adjustment mode, the side register is turned by rotating the shaft 9 set. In this operating mode, the socket 10 is held by the socket drive. The shaft drive drives the gear 18, and this in turn rotates the shaft 9 either in Clockwise or counterclockwise. Since the shaft 9 with the mother plates 14, 15 and the socket 10 is in threaded connection, the shaft 9 is driven laterally, namely in a direction corresponding to the direction of rotation. The shaft 9 pushes or pulls the Plate cylinder 1 in the lateral direction by power transmission via the shaft bearing 11 in this way the plate cylinder 1 is adjusted laterally.

In einem zweiten Verstellmodus wird das umfängliche Register durch Drehen der Buchse 10 eingestellt. In dieser Betriebsart wird die Welle 9 durch den Wellenantrieb festgehalten. Der Buchsenantrieb treibt das Kegelrad 24, das wiederum die Buchse dreht, entweder im Uhrzeigersinn oder im Gegenuhrzeigersinn. Da die Buchse 10 in Gewindeverbindung mit der festgehaltenen Welle 9 steht, wird die Buchse 10 seitlich getrieben in einer der Drehrichtung entsprechenden Richtung.In a second adjustment mode, the extensive register is turned by turning the socket 10 set. In this operating mode, the shaft 9 is held by the shaft drive. Of the Bush drive drives the bevel gear 24, which in turn rotates the bush, either in Clockwise or counterclockwise. Since the socket 10 is in threaded connection with the held shaft 9, the socket 10 is driven laterally in one of the directions of rotation corresponding direction.

Die Buchse 10 überträgt Seiterkräfte über ihre Lager 25, danach über die Ringeinheit 26 und weiter über die Schrauben 33 auf das Schrägrad 32. Das Schrägrad 32 wird auf diese Weise seitlich bewegt in einer der Drehrichtung der Buchse 10 entsprechenden Richtung. Da das Schrägrad 32 mit dem Schrägrad 8 des Gummizylinders in Eingriff steht, wird das Schrägrad 32 zu umfänglicher Drehung bezüglich des Gummiyzlinders 5 gezwungen. Die Umfangsbewegung des Schrägrads 32 bezüglich des Gummizylinders 8 überträgt Umfangskräfte über den geraden Keil 34, wodurch umfängliches Drehen des Plattenzylinders 1 bezüglich des Gummizylinders 5 bewirkt wird. Auf diese Weise wird eine Registerhaltigkeit in Umfangsrichtung erzielt.The bushing 10 transmits lateral forces via its bearings 25, then via the ring unit 26 and continue on the screws 33 to the bevel 32. The bevel 32 is in this way moved laterally in a direction corresponding to the direction of rotation of the bushing 10. Since that Bevel 32 with the bevel 8 of the blanket cylinder engages, the bevel 32 forced to circumferential rotation with respect to the rubber cylinder 5. The Circumferential movement of the bevel 32 with respect to the blanket cylinder 8 transmits Circumferential forces over the straight wedge 34, causing circumferential rotation of the plate cylinder 1 is effected with respect to the blanket cylinder 5. In this way, a register is maintained achieved in the circumferential direction.

Entsprechend der Fig. 4 werden im Maschinenbetrieb der Plattenzylinder 1 und der Gummizylinder 5 gedreht, beispielsweise durch einen Getriebezug 300, der an ein Hauptantriebsgetriebe 310 angeschlossen ist. Das Getriebe 310 wird durch einen Gleichstrommotor über einen Riemen (nicht gezeigt) angetrieben. Die Lagerzapfen 2 des Plattenzylinders, das Schrägrad 32, der gerade Keil 34, das Stirnrad 35, die Schrauben 33 und die Ringe 12, 26 rotieren zusammen mit dem Plattenzylinder 1. Das Schrägrad 8 und die Lagerzapfen 6 des Gummiyzlinders rotieren zusammen mit diesem. Die Welle 9 und die Buchse 10 mit Lagerung, wie durch ihre Lager 11, 25, rotieren nicht zusammen mit dem Plattenzylinder 1. Wenn die Maschine läuft, wird die Welle 9 durch den Wellenantrieb festgehalten und die Buchse 10 wird durch den Buchsenantrieb festgehalten, außer wenn das Register bei laufender Maschine eingestellt wird (wie vorstehend beschrieben).4, the plate cylinder 1 and the Rubber cylinder 5 rotated, for example, by a gear train 300, the one Main drive gear 310 is connected. The transmission 310 is replaced by a DC motor driven by a belt (not shown). The journal 2 of the Plate cylinder, the bevel 32, the straight wedge 34, the spur gear 35, the screws 33 and the rings 12, 26 rotate together with the plate cylinder 1. The bevel 8 and the Bearing journals 6 of the rubber cylinder rotate together with this. The wave 9 and the Bushing 10 with storage, as through its bearings 11, 25, do not rotate together with the Plate cylinder 1. When the machine is running, the shaft 9 is driven by the shaft and the socket 10 is held by the socket drive, unless that Register is set while the machine is running (as described above).

Fig. 5 zeigt eine andere Ausführungsform der vorliegenden Erfindung, bei der die Schrägräder 8, 32 der Ausführungsform von Fig. 2 durch Stirnräder 88, 82 ersetzt sind und der gerade Keil 34 der Ausführungsform von Fig. 2 durch einen Schraubenkeil 84 ersetzt ist. Zusätzlich ist das Zahnrad 18 des Wellenantriebs durch ein Zahnrad 36 ersetzt. Komponenten; die einander bei den Ausführungsformen der Fig. 2 und 5 entsprechen, haben gleiche Bezugszeichen.Fig. 5 shows another embodiment of the present invention, in which the Helical gears 8, 32 of the embodiment of FIG. 2 are replaced by spur gears 88, 82 and the straight wedge 34 of the embodiment of FIG. 2 is replaced by a screw wedge 84. In addition, the gear 18 of the shaft drive is replaced by a gear 36. Components; which correspond to one another in the embodiments of FIGS. 2 and 5 have the same Reference numerals.

Wie die Fig. 5 zeigt, wird die Welle 9 bei der Einstellung des Seitenregisters an einer Rotation gegenüber der Registerantriebsplatte 17 durch einen Stift 39 gehindert, der in die Welle 9 eingepreßt ist und in einer Nut in der Platte 17 sitzt. Zusätzlich ist ein Halter 37 in der Registerantriebsplatte 17 mit einer Schraube 38 befestigt und verhindert eine axiale Bewegung des Zahnrads 36. Zum Verstellen des Seitenregisters wird das Zahnrad 36 durch den ersten Motor gedreht, während der Buchsenantrieb (Zahnräder 24, 21, Welle 23, Ritzel 22 und zweiter Motor) festgehalten wird. Wenn das Zahnrad 36 rotiert, bewegt es die Welle 9 axial, nicht aber umfänglich infolge der Gewindeverbindung zwischen der Welle 9 und dem Zahnrad 36.As shown in Fig. 5, the shaft 9 rotates when the side register is set prevented from the register drive plate 17 by a pin 39 which in the shaft 9th is pressed and sits in a groove in the plate 17. In addition, a holder 37 in the Register drive plate 17 fastened with a screw 38 and prevents axial Movement of the gear 36. To adjust the side register, the gear 36 is rotated the first motor while the bush drive (gears 24, 21, shaft 23, pinion 22 and second motor) is held. When the gear 36 rotates, it moves the shaft 9 axially, but not circumferentially due to the threaded connection between the shaft 9 and the Gear 36.

Eine Verstellung des Seitenregisters wird ähnlich wie in Fig. 2 erzielt, abgesehen davon, daß die Buchse 10 bei ihrer Drehung eine seitliche Kraft über ihre Lager 25, danach über die Ringeinheit 26 und weiter über die Schrauben 33 auf das Stirnrad 82 überträgt. Das Stirnrad 82 wird auf diese Weise seitlich bewegt in einer Richtung, die durch die Drehrichtung der Buchse 10 bestimmt wird. Da das Stirnrad 82 mit dem Stirnrad 88 des Gummizylinders in Eingriff steht, kann das Stirnrad 82 sich bezüglich des Gummizylinders 5 nur in seitlicher Richtung nicht aber umfänglich bewegen. Die Seitenbewegung des Stirnrads 82 bezüglich des Gummizylinder-Stirnrads 88 führt zu einer Übertragung einer Umfangskraft über den Schraubenkeil 84, wodurch der Plattenzylinder 1 bezüglich des Gummizylinders 5 in Umfangsrichtung gedreht wird. An adjustment of the page register is achieved similar to that in Fig. 2, except that the socket 10 during its rotation a lateral force on its bearings 25, then on the Ring unit 26 and further transmitted via the screws 33 to the spur gear 82. The In this way, spur gear 82 is moved laterally in a direction through which Direction of rotation of the socket 10 is determined. Since the spur gear 82 with the spur gear 88 of the Is engaged, the spur gear 82 can with respect to the blanket cylinder 5th only move sideways but not extensively. The sideways movement of the Spur gear 82 with respect to the rubber cylinder spur gear 88 leads to a transmission Circumferential force over the screw wedge 84, whereby the plate cylinder 1 with respect to the Rubber cylinder 5 is rotated in the circumferential direction.
