Description

Die Erfindung betriff eine Antriebsvorrichtung für eine Walze, vorzugsweise in Offsetdruckmaschinen nach dem Oberbegriff des Hauptanspruches.
Aus der DE-PS 1 411 118 ist ein Feuchtwerk bekannt, bei dem das Feuchtmittel aus einem Feuchtmittelbehälter (Wasserkasten) mittels einer Tauchwalze (Feuchtduktor) zu einer Dosierwalze gefördert und weiter an eine nachgeordnete Farbauftragwalze übertragen wird. Die Tauchwalze wird dabei von einem separaten Antrieb über ein Zugmittelgetriebe in Drehbewegung gesetzt. Um die zu übertragende Feuchtmittelmenge einstellen zu können, ist die Drehzahl der Tauchwalze regelbar. Die Lösung weist keine axiale Verreibung der Walze auf.The invention relates to a drive device for a roller, preferably in offset printing machines according to the preamble of the main claim.
From DE-PS 1 411 118 a dampening unit is known in which the dampening solution is conveyed from a dampening solution container (water tank) by means of an immersion roller (dampening roller) to a metering roller and is further transferred to a downstream inking roller. The dip roller is set in rotation by a separate drive via a traction mechanism. In order to be able to adjust the amount of dampening solution to be transferred, the speed of the immersion roller can be regulated. The solution shows no axial rubbing of the roller.

Eine weitere Lösung ist aus der DE 3 623 590 C2 bekannt, bei der die Tauchwalze (Feuchtduktor) über einen separaten Getriebemotor mittels Getriebezug eine Drehbewegung als auch eine axiale Hin- und Herbewegung (Verreibung) erhält. Der Drehantrieb der Tauchwalze ist dabei getriebetechnisch mit dem Axialantrieb starr gekoppelt, so daß die Antriebsdrehzahl synchron mit der axialen Verreibung verändert wird. Der Getriebezug ist von einem Antriebsmotor mittels Kupplung entkoppelbar.Another solution is known from DE 3 623 590 C2, in which the dipping roller (Damp duct) a rotary motion via a separate gear motor using a gear train as well as an axial back and forth movement (trituration). The rotary drive of the Submerged roller is rigidly coupled in terms of gear technology to the axial drive, so that the Drive speed is changed synchronously with the axial friction. The gear train is can be decoupled from a drive motor by means of a coupling.

Nachteilig bei dieser Lösung ist es, das der Getriebezug lediglich komplett entkoppelt werden kann. D. h. bei Entkopplung von Antriebsmotor und Getriebezug wird die Drehbewegung als auch die axiale Verreibung stillgesetzt. Ist der Getriebezug mit dem Antriebsmotor gekoppelt, so besteht die Gefahr, das zuviel Feuchtmittel an die Druckplatte beziehungsweise in das Farbwerk gefördert wird. Dies wirkt sich negativ auf die Druckqualität aus. The disadvantage of this solution is that the gear train is only completely decoupled can. That is, when the drive motor and gear train are uncoupled, the rotary movement as well as the axial friction stopped. Is the gear train with the drive motor coupled, there is a risk of too much dampening solution on the pressure plate or is promoted to the inking unit. This has a negative impact on print quality out.

Aus der US 3 635 167 ist eine Offsetdruckmaschine mit einem Antrieb für den Plattenzylinder sowie Walzen bekannt. In einem Kettentrieb ist eine Zangsabtriebseinheit in Form eines Kettenrades mit Stummelwelle angeordnet, wobei einerseits von der Stummelwelle über eine Kurventrommel (Nutkurve) eine darin eingreifende Exzenterrolle und einen Bund der Verreibungsantrieb für zwei Walzen erfolgt und andererseits die Stummelwelle ein Zahnrad trägt, welches für den Rotationsantrieb mit Zahnrädern der beiden benachbarten Walzen gekoppelt ist.US Pat. No. 3,635,167 is an offset printing machine with a drive for the plate cylinder known as well as rollers. A pinion output unit is in shape in a chain drive a sprocket with stub shaft arranged, on the one hand from the stub shaft a cam roller engaging in it and a cam roller (groove curve) The friction drive for two rollers takes place and on the other hand the stub shaft a gear that carries for the rotation drive with gears of the two neighboring Rollers is coupled.

Weiterhin ist aus der DE 41 40 048 A1 ein Farbwerk für eine Druckmaschine mit wenigstens einer Reiberwalze bekannt. Der Verreibungsantrieb der Reiberwalze ist durch eine betätigbare Schaltkupplung bei weiter umlaufendem Druckwerk stillsetzbar bzw. zuschaltbar. Der Rotationsantrieb der Reiberwalze erfolgt mittels Zahnradgetriebe vom Plattenzylinder aus.Furthermore, DE 41 40 048 A1 describes an inking unit for a printing press with at least one known a friction roller. The friction drive of the friction roller is through a actuatable clutch can be stopped or switched on while the printing unit continues to rotate. The friction drive of the friction roller takes place by means of a gear transmission Plate cylinder.

Nachteilig bei den beiden letzten Ausführungen ist, daß beide Dokumente keine Einzelantriebe für die jeweilige Walze aufweisen. Beide Walzen sind dabei jeweils in den Druckwerksantrieb integriert. A disadvantage of the last two versions is that both documents are not individual drives have for the respective roller. Both rollers are each in the Printing unit drive integrated.

Aufgabe der Erfindung ist es deshalb, einen separaten Walzenantrieb zu entwickeln, dessen Axialantrieb (Verreibung der Walze) unabhängig vom Radialantrieb (Drehbewegung) der Walze ist. The object of the invention is therefore to develop a separate roller drive, the Axial drive (friction of the roller) independent of the radial drive (rotary movement) of the Roller is.

Gelöst wird das nach dem kennzeichnenden Teil des Hauptanspruches. Weiterbildungen ergeben sich aus den Unteransprüchen.This is solved according to the characterizing part of the main claim. Training result from the subclaims.

Die erfindungsgemäße Vorrichtung eines Walzenantriebes eignet sich für Walzen in Lackiereinrichtungen, Falbwerken und insbesondere in Feuchtwerken. Unabhängig von der Maschinengeschwindigkeit der Druckmaschine wird über den separaten Antrieb eine konstante Führung des zu fördernden Mediums, wie Lack, Farbe oder Feuchtmittel, gewährleistet. Der Axialantrieb der Walze wird vorzugsweise ständig beibehalten, der Radialantrieb der Walze erfolgt im gekoppelten Zustand synchron zum Axialantrieb. Im entkoppelten Zustand ist der Radialantrieb stillgesetzt.The device of a roller drive according to the invention is suitable for rollers in Painting equipment, folding units and especially in dampening systems. Independent of The machine speed of the printing press becomes constant via the separate drive Guidance of the medium to be conveyed, such as paint, ink or dampening solution, guaranteed. The axial drive of the roller is preferably kept constant, the radial drive in the coupled state, the roller is synchronized with the axial drive. Im decoupled The radial drive is stopped.

Für die Betriebsart "Walzen waschen" wird der Axialantrieb der Walze ebenfalls beibehalten, der Radialantrieb wird dagegen entkoppelt und somit stillgesetzt. Der Axialantrieb bewirkt, daß durch die Verreibung die Waschzeit verkürzt wird und die Walzenränder mitgewaschen werden. Damit wird in der Betriebsart "Walzen waschen" das Waschergebnis verbessert und die Dauer der Waschzeit spürbar verkürzt.The axial drive of the roller is also retained for the "washing rollers" operating mode, the radial drive, however, is decoupled and thus stopped. The axial drive causes that the washing time is shortened by the trituration and the roller edges are also washed will. This improves the washing result in the "washing rollers" mode and the duration of the washing time is noticeably reduced.

Die Kurvensteuerung 19 ist an einer axial und radial beweglichen Stange 18 befestigt, welche mit der Walze 4 gekoppelt ist.An offset printing unit consists of a plate cylinder 1, an adjacent blanket cylinder 2 and an inking unit 8 and a dampening unit. The dampening system is formed from a dampening solution tank (water tank) 3, one as a dampening roller (immersion roller) acting roller 4, which is in contact with a dampening roller 6 and a metering roller 5, which is assigned to the roller 4. Between the inking unit 8 and the Dampening unit 3 to 6, a bridge roller 7 is arranged, via which the dampening unit can be selected 3 to 6 can be coupled to the inking unit 8. In the present For example, the roller 4 should have a roller drive. On a machine frame 14 is a drive unit 9, e.g. an electric motor attached. The drive unit 9 acts on a drive member 11 designed as a gear, which preferably has a traction means 10 a toothed belt rotated. The traction means 10 is with a first Output unit for the axial drive and with a second output unit for the radial drive of the roller 4 in engagement. An output member 12 is on one on the machine frame 14 fixed storage 15 attached. The storage 15 consists inter alia. from a wave, which has an eccentric bolt on one side. The eccentric bearing 15 is with a coupling 16 rotatably connected, which on two swivel joints on one Machine frame 14 fixed angle lever 17 acts. The angle lever 17 is gear technology a ternary link and has a cam roller at one end, which is used in a cam controller 19 rotates. The cam controller 19 is axially and radially movable Fixed rod 18 which is coupled to the roller 4.

Ein Abtriebsglied 13, welches als Zahnrad aufeiner Welle 20 befestigt ist, dient dem radialen Walzenantrieb. Die Welle 20 ist im Maschinengestell 14 parallel zur Walze 4 gelagert und weist eine pneumatisch wirkende Kupplung 21 auf, welche zwischen den Wellenteilen angeordnet ist. Auf der Welle 20 ist an dem freien Ende ein Zahnrad 22 fixiert. Das Zahnrad 22 ist mit einer auf der Walze 4 angeordneten außenverzahnten Lagerbüchse 23 in Eingriff. Die Lagerbüchse 23 ist im Maschinengestell 14 gelagert und bildet gleichzeitig eine Gleitlagerung 24 für den Zapfen der Walzen 4. Die Lagerbüchse 23 ist mit einem Stift 25 mit dem Zapfen der Walze 4 oder wahlweise mit der Stange 18 verbunden. Der Stift 25 ist in radialer Richtung für die Verreibung in einer Längsführung 26 beweglich.An output member 13, which is attached as a gear on a shaft 20, serves the radial Roller drive. The shaft 20 is mounted in the machine frame 14 parallel to the roller 4 and has a pneumatically acting coupling 21, which between the shaft parts is arranged. A gear 22 is fixed on the shaft 20 at the free end. The gear 22 is in engagement with an externally toothed bearing bush 23 arranged on the roller 4. The bearing bush 23 is mounted in the machine frame 14 and at the same time forms one Slide bearing 24 for the pin of the rollers 4. The bearing bush 23 is with a pin 25 connected to the pin of the roller 4 or optionally to the rod 18. The pin 25 is movable in the radial direction for the rubbing in a longitudinal guide 26.

Das Ausführungsbeispiel stellt einen bevorzugten Walzenantrieb dar. Ebenso kann die Abtriebseinheit für den axialen Antrieb eine Kupplung aufweisen, welche vorzugsweise in dem Bereich der Lagerung 15 angeordnet ist. Alternativ dazu kann der Walzenantrieb auch über zwei Kupplungen erfolgen, für die Abtriebseinheit des axialen Antriebes im Bereich der Lagerung 15 und für die Abtriebseinheit für den radialen Antrieb im Bereich der Welle 20. The exemplary embodiment represents a preferred roller drive. The output unit can likewise have a clutch for the axial drive, which preferably in the area of the bearing 15 is arranged. Alternatively, the roller drive can also via two couplings for the output unit of the axial drive in the area the bearing 15 and for the output unit for the radial drive in the region of the shaft 20th

Die Wirkungsweise ist wie folgt:
Die Antriebseinheit 9 wird betätigt und setzt das Antriebsglied 11 in Drehbewegung. Durch das Rotieren der Antriebsglieder 11 läuft das Zugmittel 10 um und setzt die erste Abtriebseinheit 27 für den axialen Antrieb der Walze 4 in Bewegung und gleichzeitig wird vom Zugmittel 10 die zweite Abtriebseinheit 28 für den radialen Antrieb der Walze 4 in Bewegung gesetzt.The mode of action is as follows:
The drive unit 9 is actuated and sets the drive member 11 in rotary motion. By rotating the drive members 11, the traction means 10 rotates and sets the first output unit 27 for the axial drive of the roller 4 in motion and at the same time the second output unit 28 for the radial drive of the roller 4 is set in motion by the traction means 10.

Das Abtriebsglied 12 dreht sich auf der Lagerung 15 und der Exzenter setzt die Koppel 16 in Bewegung. Über den Winkelhebel 17 wird die Schwingbewegung der Koppel in eine axiale Antriebsbewegung (Verreibung) der Stange 18 umgelenkt. Die Stange 18 betätigt die Walze 4. Dabei wird der Zapfen der Walze 4 in der Gleitlagerung 24 und der Längsführung 26 der Lagerbüchse 23 geführt.The output member 12 rotates on the bearing 15 and the eccentric sets the coupling 16 in motion. About the angle lever 17, the swinging movement of the coupling in an axial drive movement (rubbing) of the rod 18 is deflected. The rod 18 actuates the roller 4. The pin of the roller 4 in the slide bearing 24 and the Longitudinal guide 26 of the bearing bush 23 out.

Das Abtriebsglied 13 dreht sich auf der Welle 20. Im gekoppelten Zustand wird das Drehmoment von der Welle 20 auf das Zahnrad 22 übertragen. Das Zahnrad 22 versetzt die Lagerbüchse 23, über deren Außenverzahnung, in eine Drehbewegung. Die Drehbewegung wird von der Lagerbüchse 23 über den Stift 25 auf die Walze 4 durch die Stange 18 übertragen. Soll die Drehbewegung der Walze 4 stillgesetzt werden, so wird die Kupplung 21 pneumatisch aktiviert, derart, daß eine getriebetechnische Entkopplung vom Abtriebsglied 13 und Zahnrad 22 erfolgt. Der das Zahnrad 22 tragende Teil der Welle 20 wird stillgesetzt, während der das Abtriebsglied 13 tragende Teil der Welle 20 weiter durch den Antrieb des Zugmittels 10 umläuft. The output member 13 rotates on the shaft 20. In the coupled state, this is Transfer torque from the shaft 20 to the gear 22. The gear 22 is offset the bearing bush 23, via its external toothing, in a rotational movement. The rotary motion is from the bearing bush 23 via the pin 25 to the roller 4 through the rod 18 transferred. If the rotary movement of the roller 4 is to be stopped, the Coupling 21 pneumatically activated, such that a technical decoupling from the output member 13 and gear 22. The part of FIG Shaft 20 is brought to a standstill while the part of shaft 20 carrying output member 13 is stopped continues to rotate by the drive of the traction means 10.
