Description

Die Erfindung betrifft eine Vorrichtung zum Verstellen von Teilen auf einem Zylinder einer Rotationsdruckmaschine gemäß dem Oberbegriff des Anspruches 1 und 7.The invention relates to a device for adjusting of parts on a cylinder one Rotary printing machine according to the preamble of Claims 1 and 7.

Die DE 35 04 435 A1 zeigt eine Vorrichtung zum Verstellen von auf einer Registerschiene befestigten Papieranschlägen. Hierzu sind mindestens drei Justierschrauben vorgesehen, die jeweils mittels eines Stellmotores verdrehbar sind.DE 35 04 435 A1 shows a device for Adjustment of fastened on a register rail Paper stops. There are at least three of them Adjustment screws are provided, each using a Actuator are rotatable.

Nachteilig an dieser Vorrichtung ist, daß aufwendige Vorrichtungen zur Übertragung von elektrischer Energie und Steuersignalen zur Steuerung der im drehenden Zylinder angeordneten Stellmotore notwendig sind.The disadvantage of this device is that it is complex Devices for the transmission of electrical energy and control signals for controlling the rotating Actuators arranged in cylinders are necessary.

Die US 31 41 384 A beschreibt einen Klinkenantrieb für einen Turbinenrotor. Dabei sind zwei Hydraulikzylinder zum Bewegen der Klinke angeordnet.The US 31 41 384 A describes a ratchet drive for a turbine rotor. There are two hydraulic cylinders arranged to move the pawl.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zum Verstellen von Teilen auf einem Zylinder einer Rotationsdruckmaschine zu schaffen, bei der eine Fernverstellung dieser Teile auch bei drehendem Zylinder möglich ist, ohne daß elektrische Energie auf den drehenden Zylinder übertragen werden muß. The invention has for its object a Device for moving parts on a cylinder to create a rotary printing press in which one Remote adjustment of these parts even when the cylinder is rotating is possible without electrical energy on the rotating cylinder must be transmitted.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des kennzeichnenden Teiles der Ansprüche 1 und 7 gelöst.This object is achieved by the features of the characterizing part of claims 1 and 7 solved.

Die mit der Erfindung erzielbaren Vorteile bestehen insbesondere darin, daß aufwendige Drehübertrager, wie z. B. verschleißanfällige Schleifringübertrager, zum übertragen von elektrischer Energie nicht benötigt werden. Durch Ausführen von kleinen diskreten Verstellschritten können Rückmeldesensoren entfallen. Die Anzeige der Stellung der Teile, z. B. der Vorderanschläge, kann durch einfaches Zählen von Stellimpulsen außerhalb des Zylinders erfolgen. Vorteilhaft ist zudem, daß auf dem Zylinder keine elektrischen Bauteile verwendet werden. Somit eignet sich die erfindungsgemäße Vorrichtung besonders zur Verwendung in Bereichen, in denen ansonsten explosionsgeschützte Bauteile verwendet werden müssen, z. B. in Bogentiefdruckmaschinen.The advantages that can be achieved with the invention exist especially in the fact that complex rotary transformers, such as e.g. B. wear-prone slip ring transmitters, for transfer of electrical energy not required become. By running small discrete ones Adjustment steps can be dispensed with feedback sensors. The display of the position of the parts, e.g. B. the Front stops, can be done by simply counting Adjustment impulses take place outside the cylinder. It is also advantageous that none on the cylinder electrical components are used. Thus suitable the device according to the invention is particularly suitable for Use in areas where otherwise explosion-proof components must be used, e.g. B. in gravure printing machines.

Die erfindungsgemäße Vorrichtung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben.The device according to the invention is in the drawing shown and is described in more detail below.

In einer Anlage einer Bogenrotationsdruckmaschine ist ein erster, bogenübernehmender Zylinder 1 mit Vordermarken 2 und auf einer Spindel 3 gelagerten Greifern 4 versehen. An diesem Zylinder 1 erfolgt die Anlage und Ausrichtung von Bogen, die in der Bogenrotationsdruckmaschine verarbeitet werden. Mindestens zwei dieser Vordermarken 2 sind in ihrer Nullstellung parallel zu einer Drehachse 6 des Zylinders 1 an seinem Umfang angeordnet. Im vorliegenden Ausführungsbeispiel ist eine Vielzahl von Vordermarken 2 auf einer gemeinsamen Registerschiene 7 befestigt. Diese Registerschiene 7 ist in tangentialer Richtung bezüglich des Zylinders 1 verschiebbar gelagert. Zur Ausführung dieser Verstellbewegung sind an beiden Enden sowie in der Mitte der Registerschiene 7 in einem Körper 8 des Zylinders 1 verschiebbar gelagerte Gewindebolzen 9 befestigt. An einem der Registerschiene 7 abgewandten Ende 11 der Gewindebolzen 9 ist ein mit einem zentrischen Innengewinde versehenes Zahnrad 12, das drehbar, aber ansonsten ortsfest ist, aufgeschraubt. Dieses Zahnrad 12 stützt sich mittels eines Axiallagers 13 mit einer Stirnseite 14 am Körper 8 des Zylinders 1 ab und bildet somit ein Gegenlager für die von Druckfedern 16 erzeugte, auf die Registerschiene 7 in tangentialer Richtung des Zylinder 1 wirkende Kraft. Die Druckfedern 16 sind zwischen der Registerschiene 7 und dem Körper 8 des Zylinders 1 angeordnet. Im Körper 8 des Zylinders 1 ist ein erster Stift 17, und im Zahnrad 12 ein zweiter Stift 18 befestigt, die zusammen als Anschlag für das Zahnrad 12 in Umfangsrichtung wirken.
Mit dem Zahnrad 12 zusammenwirkend sind zwei Antriebsklinken 19 tangential bezüglich eines Wälzkreises 21 des Zahnrades 12 linear bewegbar gelagert. Diese Antriebsklinken 19 sind auf einem Grundträger 22 bezüglich der Umfangsrichtung des Zahnrades 12 schwenkbar gelagert und werden mittels Druckfedern 23 in eine Grundstellung gegen den Grundträger 22 gedrückt.
Die Grundträger 22 mit den Antriebsklinken 19 werden von im Körper 8 des Zylinders 1 befestigten, mit Druckmittel beaufschlagbarer Arbeitszylinder, z. B. Pneumatikzylindern 24, bewegt. Hierzu sind die Grundträger 22 mit einer Bohrung 26 und die Antriebsklinken 19 mit einem Langloch 27 versehen, durch die bzw. das jeweils eine Kolbenstange 28 des Pneumatikzylinders 24 führt. Zur Abstützung des Grundträgers 22 ist eine Gewindemutter 29 auf die Kolbenstange 28 aufgeschraubt und zur Abstützung der Druckfeder 23 ist eine zweite Gewindemutter 31 am Ende der Kolbenstange 28 angeordnet. Im vorliegenden Beispiel sind die Pneumatikzylinder 24 bezüglich einer durch eine Drehachse 32 des Zahnrades 12 verlaufende Symmetrieachse 33 parallel und symmetrisch angeordnet. Zwischen den Pneumatikzylindern 24 ist eine auf eine Zahnlücke 34 des Zahnrades 12 wirkende, gefederte Kugelraste 36 im Körper 8 des Zylinders 1 befestigt.In a system of a sheet-fed rotary printing press, a first cylinder 1, which takes over the sheet, is provided with front marks 2 and grippers 4 mounted on a spindle 3. On this cylinder 1, sheets are created and aligned, which are processed in the sheet-fed rotary printing press. At least two of these front marks 2 are arranged in their zero position parallel to an axis of rotation 6 of the cylinder 1 on its circumference. In the present exemplary embodiment, a plurality of front marks 2 are fastened on a common register rail 7. This register rail 7 is slidably mounted in the tangential direction with respect to the cylinder 1. To carry out this adjustment movement threaded bolts 9 are slidably mounted at both ends and in the middle of the register rail 7 in a body 8 of the cylinder 1. On one end 11 of the threaded bolts 9 facing away from the register rail 7, a gearwheel 12, which is provided with a central internal thread and is rotatable but otherwise stationary, is screwed on. This gear wheel 12 is supported by an axial bearing 13 with an end face 14 on the body 8 of the cylinder 1 and thus forms a counter bearing for the force generated by compression springs 16 and acting on the register rail 7 in the tangential direction of the cylinder 1. The compression springs 16 are arranged between the register rail 7 and the body 8 of the cylinder 1. A first pin 17 is fastened in the body 8 of the cylinder 1, and a second pin 18 is fastened in the gear 12, which together act as a stop for the gear 12 in the circumferential direction.
Interacting with the gear 12, two drive pawls 19 are mounted so as to be linearly movable tangentially with respect to a pitch circle 21 of the gear 12. These drive pawls 19 are pivotably mounted on a base support 22 with respect to the circumferential direction of the gear wheel 12 and are pressed into a basic position against the base support 22 by means of compression springs 23.
The base bracket 22 with the drive pawls 19 are attached in the body 8 of the cylinder 1, pressurizable working cylinder, for. B. pneumatic cylinders 24 moves. For this purpose, the base supports 22 are provided with a bore 26 and the drive pawls 19 are provided with an elongated hole 27 through which a piston rod 28 of the pneumatic cylinder 24 leads. A threaded nut 29 is screwed onto the piston rod 28 to support the base support 22 and a second threaded nut 31 is arranged at the end of the piston rod 28 to support the compression spring 23. In the present example, the pneumatic cylinders 24 are arranged parallel and symmetrically with respect to an axis of symmetry 33 running through an axis of rotation 32 of the gear wheel 12. A spring-loaded ball catch 36 acting on a tooth gap 34 of the gear 12 is fastened in the body 8 of the cylinder 1 between the pneumatic cylinders 24.

Die Funktionsweise der erfindungsgemäßen Vorrichtung ist folgendermaßen:
Aufgrund schräger, konvex oder konkav geschnittener Vorderkanten der zu verarbeitenden Bogen müssen die Vordermarken 2 auf die Vorderkante angepaßt werden. Hierzu wird die Registerschiene 7 mittels mindestens einer erfindungsgemäßen Vorrichtung schräg verschoben oder verbogen. Zur tangentialen Verstellung der Registerschiene 7 wird wahlweise ein Pneumatikzylinder 24 betätigt. Dieser verschiebt die sich am Grundträger 22 abstützende Antriebsklinke 19 in tangentialer Richtung bezüglich des Wälzkreises 21. Dabei greift die Antriebsklinke 19 an einem Zahn 37 des Zahnrades 12 an und verdreht das Zahnrad 12 um einen entsprechenden Drehwinkel. Hierbei ist die auf das Zahnrad 12 wirkende Antriebskraft infolge der Antriebsklinke 19 größer als die wirkende Haltekraft der Kugelraste 36 und die benötigte Verstellkraft. Die Kugelraste 36 federt während der Verstellbewegung zurück und rastet in eine nächste Zahnlücke 34 ein. Der Pneumatikzylinder 24 wird entlüftet und führt eine Rückstellbewegung des Grundträgers 22 aus. Dabei ist das Zahnrad 12 mittels der Kugelraste 36 fixiert. Während der Rückstellbewegung stößt die Antriebsklinke 19 an einem nachfolgenden Zahn 37 an und führt eine Schwenkbewegung gegen die Druckfeder aus. Dadurch gleitet die Antriebsklinke 19 an dem Zahn 37 vorbei und schwenkt anschließend wieder zurück, so daß die Antriebsklinke 19 wieder am Grundträger 22 anliegt. Dieser Vorgang kann beliebig wiederholt werden bis die Registerschiene 7 die gewünschte Stellung erreicht hat. Mit der rechten Antriebsklinke 19 wird das Zahnrad 12 entgegen dem Uhrzeigersinn gedreht, während mit der linken Antriebsklinke 19 eine Verdrehung des Zahnrades 12 im Uhrzeigersinn erzielt wird. Durch die Drehbewegung des Zahnrades 12 wird mittels des Gewindes eine Verschiebung des Gewindebolzens 9 und damit der Registerschiene 7 erreicht.The operation of the device according to the invention is as follows:
Due to the oblique, convex or concave cut front edges of the sheets to be processed, the front marks 2 must be adjusted to the front edge. For this purpose, the register rail 7 is shifted or bent obliquely by means of at least one device according to the invention. A pneumatic cylinder 24 is optionally actuated for the tangential adjustment of the register rail 7. This moves the driving pawl 19 supported on the base support 22 in the tangential direction with respect to the pitch circle 21. The driving pawl 19 engages a tooth 37 of the gear 12 and rotates the gear 12 by a corresponding angle of rotation. Here, the driving force acting on the gear 12 due to the drive pawl 19 is greater than the acting holding force of the ball catch 36 and the required adjusting force. The ball catch 36 springs back during the adjustment movement and engages in a next tooth gap 34. The pneumatic cylinder 24 is vented and performs a return movement of the base support 22. The gear 12 is fixed by means of the ball catch 36. During the resetting movement, the drive pawl 19 abuts a subsequent tooth 37 and carries out a pivoting movement against the compression spring. As a result, the drive pawl 19 slides past the tooth 37 and then pivots back again, so that the drive pawl 19 bears against the base support 22 again. This process can be repeated any number of times until the register rail 7 has reached the desired position. With the right drive pawl 19, the gear 12 is rotated counterclockwise, while with the left drive pawl 19, the gear 12 is rotated clockwise. The rotational movement of the gear wheel 12 causes the threaded bolt 9 and thus the register rail 7 to be displaced by means of the thread.

Die schwenkbare Antriebsklinke 19 kann beispielsweise auch als sich gegen den Grundträger 22 abstützende Blattfeder ausgeführt sein.The pivotable drive pawl 19 can, for example also as a support against the base support 22 Leaf spring to be executed.

Zur Justage der Vorrichtung führt ein Pneumatikzylinder 24 mehr Hübe aus als der maximale Verstellweg zuläßt. Dadurch schlägt der Stift 18 des Zahnrades 12 gegen den Stift 17 an und befindet sich somit in einer definierten Lage. Von dieser Lage aus kann eine nicht dargestellte Steuerung der Pneumatikzylinder 24 jede Lage der Gewindebolzen 9 der Registerschiene 7 in diskreten Schritten anfahren.A pneumatic cylinder leads to the adjustment of the device 24 more strokes than the maximum adjustment range allows. Characterized the pin 18 of the gear 12 strikes against the Pin 17 and is thus in a defined Location. From this location, one not shown Control of the pneumatic cylinder 24 any position Threaded bolt 9 of the register rail 7 in discrete Approach steps.

Mit dieser Vorrichtung kann bei radialer Anordnung der Gewindebolzen (9) auch eine Höhenverstellung der Vordermarken (2) erfolgen, wenn diese entsprechend gelagert sind. With this device, the radial arrangement of the Threaded bolt (9) also a height adjustment Front marks (2) are made if these are appropriate are stored.

Diese erfindungsgemäße Vorrichtung zum Verstellen ist auch geeignet, anstelle der Vordermarken andere Teile (z. B. Platten-Klemmeinrichtungen, Registerstifte) auf anderen Zylindern (z. B. Plattenzylinder) einer Rotationsdruckmaschine zu verstellen.This adjustment device according to the invention is also suitable, other parts instead of the front brands (e.g. plate clamping devices, register pins) other cylinders (e.g. plate cylinders) one Rotary press to adjust.

Die Verstellbewegung wird mittels impulsgesteuertem Arbeitszylinder in diskreten Schritten ausgeführt. The adjustment movement is controlled by means of a pulse Working cylinders executed in discrete steps.
