Description

Die Erfindung betrifft eine Antriebsvorrichtung für das Farb- und Feuchtwerk einer Rotationsdruckmaschine mit mehreren changierenden Reibwalzen, die über Zahnräder von einer Verzahnung am Plattenzylinder antreibbar sind, wobei auf einer mindestens einseitig gestellfest gelagerten Welle ein mit der Verzahnung des Plattenzylinders kämmendes Antriebszahnrad angeordnet ist, daß auf einer weiteren ortsfesten Welle für jede Reibwalze ein längs des Wellenumfanges verdrehbarer Exzenter fixierbar ist, daß auf den Exzentern über Lager Schwinghebel angeordnet sind, und daß die im Rhythmus der rotierenden Exzenter in Axialrichtung der Reibwalzen hin- und hergehenden Exzenterbewegungen über Koppelelemente jeweils zwischen den Schwinghebeln und den Achsstummeln der Reibwalzen auf letzere übertragbar sind.The invention relates to a drive device for the inking and dampening unit of a rotary printing press with a plurality of oscillating friction rollers which can be driven by gears from a toothing on the plate cylinder, a drive gear meshing with the toothing of the plate cylinder being arranged on an at least one-sided frame-fixed shaft that is arranged on a further stationary shaft for each friction roller, an eccentric that can be rotated along the shaft circumference can be fixed, that rocking levers are arranged on the eccentrics via bearings, and that the eccentric movements reciprocating in the rhythm of the rotating eccentrics in the axial direction of the friction rollers via coupling elements in each case between the rocking levers and the stub axles of the friction rollers can be transferred to the latter.

Aus der DE-AS 2 309 850 ist ein Farbwerk bekannt, das eine Anzahl Reibzylinder umfaßt, die vom Plattenzylinder her über Zahnräder aufweisende Getriebezüge antreibbar sind. Üblicherweise werden zwecks besserer Verreibung die Reibzylinder auch in Axialrichtung, d. h. changierend, angetrieben. Wie beispielsweise die DE-AS 2 514 414 zeigt, wird zur Erzeugung der Changierbewegungen der Reibzylinder ein separater Antriebsmechanismus verwendet, der besonders dann recht aufwendig ist, wenn verschiedene Einstellmöglichkeiten hinsichtlich Changierhub und Phasenlage der Changierbewegung gefordert werden.From DE-AS 2 309 850 an inking unit is known which comprises a number of distribution cylinders which can be driven from the plate cylinder via gear trains having gear wheels. Usually, the friction cylinders are also in the axial direction, ie. H. iridescent, driven. As is shown, for example, in DE-AS 2 514 414, a separate drive mechanism is used to generate the traversing movements of the distribution cylinders, which is particularly complex when different adjustment options with regard to traversing stroke and phase position of the traversing movement are required.

Aus der US-A-1 977 414 ist eine Vorrichtung der eingangs bezeichneten Gattung bekannt, bei der die Rotationsbewegung der Reibwalzen über einen Antriebsräderzug mit mehreren überbreiten Zwischenstirnrändern realisiert wird. Die Changierbewegung wird über einen separaten, parallelen Antrieb den einzelnen Reibwalzen zugeleitet. Diese Vorrichtung ist voluminös und damit entsprechend aufwendig.From US-A-1 977 414 a device of the type mentioned at the outset is known, in which the rotational movement of the friction rollers is implemented by means of a drive wheel train with a plurality of wide intermediate end edges. The traversing movement is fed to the individual distribution rollers via a separate, parallel drive. This device is voluminous and therefore correspondingly expensive.

Aufgabe der Erfindung ist es, eine besonders kompakt gebaute Antriebsvorrichtung für die Reiber in einem Farb- und/oder Feuchtwerk zu schaffen, mit dem sowohl der Rotationsantrieb als auch der Changierantrieb für die Reibwalzen vom Plattenzylinder abgeleitet und den Reibwalzen zur Verfügung gestellt werden kann, wobei eine individuelle zeitliche Einflußnahme auf die Totlagen des Changierhubes bei einer jeden Reibwalze möglich sein soll.The object of the invention is to provide a particularly compact drive device for the friction in a inking and / or dampening unit, with which both the rotary drive and the traversing drive for the friction rollers can be derived from the plate cylinder and made available to the friction rollers, whereby an individual temporal influence on the dead positions of the traversing stroke should be possible for each friction roller.

Diese Aufgabe wird durch die Verwendung der Merkmale des Kennzeichens des Anspruches 1 gelöst. Weiterbildungen ergeben sich aus den Unteransprüchen sowie aus der Beschreibung in Verbindung mit den Zeichnungen.This object is achieved by using the features of the characterizing part of claim 1. Further developments result from the subclaims and from the description in conjunction with the drawings.

Durch die unmittelbare Positionierung des Zentralzahnrades neben dem Plattenzylinder und die Anordnung der Antriebszahnräder der Reibwalzen um das Zentralzahnrad herum ist ein einfacher und kompakt bauender Rotationsantrieb der Reibwalzen für das Farb- und/oder Feuchtwerk möglich. Gleichzeitig dient der genannte Antrieb in vorteilhafter Weise zur Erzeugung der Changierbewegung für die Reibwalzen, wobei durch Verdrehen der einer jeden Reibwalze zugeordneten Exzenter in einfacher Weise die Phasenlage des Changierhubes veränderbar ist. Vorzugsweise werden die Exzenter so verdreht, daß niemals alle Reibwalzen gleichzeitig in die End- bzw. Totlage kommen, d. h. nicht gleichzeitig den Umkehrpunkt erreichen, was wesentlich zu der geforderten Vergleichmäßigung der zu verreibenden Farb- und/oder Feuchtmittelschichten bzw. -filme beiträgt.Due to the immediate positioning of the central gear next to the plate cylinder and the arrangement of the drive gears of the friction rollers around the central gear, a simple and compact rotary drive of the friction rollers for the inking and / or dampening unit is possible. At the same time, the drive mentioned advantageously serves to generate the traversing movement for the friction rollers, the phase position of the traversing stroke being able to be changed in a simple manner by rotating the eccentrics assigned to each friction roller. Preferably, the eccentrics are rotated so that all the friction rollers never come to the end or dead position at the same time, i. H. do not reach the reversal point at the same time, which contributes significantly to the required leveling of the ink and / or dampening solution layers or films to be rubbed.

Im folgenden wird die Erfindung anhand eines Ausführungsbeispieles im einzelnen beschrieben, wobei Bezug auf die Zeichnungen genommen wird. In diesen zeigt

Fig. 1 zeigt schematisch ein Druckwerk 1, das drei Gummizylinder 2, 3 und 4 sowie drei jeweils an einen der genannten Gummizylinder 2 bis 4 angestellte Plattenzylinder 5, 6 und 7 umfaßt. Jedem der Plattenzylinder 5 bis 7 ist ein Farbwerk und ein Feuchtwerk zugeordnet. In Fig. 1 sind der Übersicht halber lediglich die plattenzylindernahen Farb- und Feuchtwalzen und -reiber gezeigt. Da die erfindungsgemäße Antriebsvorrichtung an jedem der Plattenzylinder 5 bis 7, d. h. in allen geometrischen Einbaulagen, verwendbar ist, wird die Erfindung lediglich anhand der dem Plattenzylinder 5 zugeordneten Antriebsvorrichtung beschrieben.Fig. 1 shows schematically a printing unit 1, which comprises three blanket cylinders 2, 3 and 4 as well as three plate cylinders 5, 6 and 7, each placed on one of the blanket cylinders 2 to 4 mentioned. An inking unit and a dampening unit are assigned to each of the plate cylinders 5 to 7. In Fig. 1, for the sake of clarity, only the ink and dampening rollers and rubbers near the plate cylinders are shown. Since the drive device according to the invention on each of the plate cylinders 5 to 7, i. H. is usable in all geometric installation positions, the invention is described only with reference to the drive device assigned to the plate cylinder 5.

An den Plattenzylinder 5 sind Farbauftragwalzen 8, 9 und eine Feuchtauftragwalze 10 angestellt. Die Farbauftragwalzen 8, 9 erhalten Farbe von einer Farbreibwalze 11 und einer Farbreibwalze 12 und die Feuchtauftragwalze 10 erhält Feuchtflüssigkeit über die Feuchtreibwalze 13, wobei zwischen den Farbreibwalzen 11 und 12 eine Farbwerkwalze 14 angeordnet ist und der Farbreibwalze 12 die Farbe von einem in Fig. 1 nicht mehr dargestellten Farbkasten kommend über eine Farbwerkwalze 15 zugeführt wird.Ink application rollers 8, 9 and a dampening application roller 10 are set on the plate cylinder 5. The inking rollers 8, 9 receive ink from an inking roller 11 and an inking roller 12 and the dampening roller 10 receives dampening liquid via the dampening roller 13, wherein an inking roller 14 is arranged between the inking rollers 11 and 12 and the inking roller 12 receives the ink from one in FIG. 1 Ink box not shown coming is fed via an inking roller 15.

Die Farbreibwalzen 11 und 12 sowie die Feuchtreibwalze 13 werden durch ein zwischen diesen angeordnetes Zentralzahnrad 16 in Drehung versetzt, das seinerseits durch den Plattenzylinder 5 angetrieben wird. Bei der in Fig. 1 gezeigten Papierbahnführung kann eine Papierbahn 17 durch die Gummizylinder 2 und 4 mit einem zweifachen Schöndruck und durch den Gummizylinder 3 mit einem Widerdruck versehen werden. Selbstverständlich sind auch andere Papierbahnführungen möglich. Wie Fig. 1 erkennen läßt, kann das im Zusammenhang mit dem Plattenzylinder 5 beschriebene Farb- und Feuchtwerk auch an dem Plattenzylinder 6 und an dem Plattenzylinder 7 verwendet werden. Diesbringtwesentliche Rationalisierungsvorteile.The inking rollers 11 and 12 and the dampening roller 13 are rotated by a central gear 16 arranged between them, which in turn is driven by the plate cylinder 5. In the paper web guide shown in FIG. 1, a paper web 17 can be provided with a double face print through the rubber cylinders 2 and 4 and with a back pressure through the rubber cylinder 3. Of course, other paper web guides are also possible. As can be seen in FIG. 1, the color and described in connection with the plate cylinder 5 Dampening can also be used on the plate cylinder 6 and on the plate cylinder 7. This brings substantial rationalization advantages.

Im folgenden wird unter Bezugnahme auf die Fig. 2, 3 und 4 die erfindungsgemäße Antriebsvorrichtung im einzelnen beschrieben. Wie bereits im Zusammenhang mit der Beschreibung der Fig. 1 erwähnt, erfolgt der Antrieb des Zentralzahnrades 16 vom Plattenzylinder 5 her. Aus den Fig. 3 und 4 ist erkennbar, daß mit einer Schrägverzahnung 18 am Plattenzylinder ein schrägverzahntes Antriebszahnrad 19 kämmt, das auf einer Welle 20 angeordnet ist, die in der Maschinenseitenwand 21 der Druckmaschine, die üblicherweise als Seite II (Antriebsseite) gezeichnet wird, gelagert ist.The drive device according to the invention is described in detail below with reference to FIGS. 2, 3 and 4. As already mentioned in connection with the description of FIG. 1, the central gear 16 is driven by the plate cylinder 5. 3 and 4 it can be seen that a helical toothing 18 meshes with a helical toothing 18 on the plate cylinder, which is arranged on a shaft 20 which is located in the machine side wall 21 of the printing press, which is usually drawn as side II (drive side), is stored.

Auf der Welle 20 ist außerdem das Zentralzahnrad 16 aufgezogen und am Ende der Welle 20 (Fig. 4) ist ein Kegeltrieb 31 gezeigt, über den die Welle 20 eine rechtwinklig zu dieser angeordnete Welle 32 antreibt.The central gear 16 is also mounted on the shaft 20 and at the end of the shaft 20 (FIG. 4) a bevel drive 31 is shown, via which the shaft 20 drives a shaft 32 arranged at right angles to this.

Auf den Achsstummeln 22, 23 und 24 der Farbreibwalzen 11 und 12 bzw. der Feuchtreibwalze 13 sind Antriebszahnräder 11', 12' und 13' aufgezogen, die mit dem Zentralzahnrad 16 kämmen, so daß durch letzteres die Reiber 11 bis 13 von dem Plattenzylinder 5 her antreibbar sind.On the stub axles 22, 23 and 24 of the inking rollers 11 and 12 and the dampening roller 13, drive gearwheels 11 ', 12' and 13 'are mounted, which mesh with the central gearwheel 16, so that the grater 11 to 13 from the plate cylinder 5 through the latter are drivable here.

Neben den Antriebszahnrädern 11', 12' und 13' sind auf jedem der Achsstummel 22, 23 und 24 ein Führungsscheibenpaar 25, 26 und 27 angeordnet, in das jeweils einer der Gleitsteine 28, 29, 30 eingreift.In addition to the drive gears 11 ', 12' and 13 ', a pair of guide disks 25, 26 and 27 are arranged on each of the stub axles 22, 23 and 24, in each of which one of the sliding blocks 28, 29, 30 engages.

Wie bereits erwähnt, wird über den Kegeltrieb 31 die quer zur Welle 20 angeordnete Welle 32 angetrieben. Die Welle 32 ist beidseitig mittels ortsfester Platten 33, 34 gelagert. Wie Fig. 2 und 4 am besten erkennen lassen, ist auf dem linken Ende der Welle 32 ein Exzenter 35 und am rechten Ende der Welle ein Exzenter 36 sowie neben diesem ein Exzenter 37 drehbar angeordnet. Durch Lösen des jeweiligen Befestigungsmittels, beispielsweise einer üblichen Fixierschraube, kann ein jeder der Exzenter 35, 36, 37 auf der Welle 32 verdreht werden. Durch die Lage der Exzenter 35, 36, 37 auf der Welle 32 ist eine individuelle zeitliche Einflußnahme auf die Changierbewegung, d. h. auf die Phasenlage des Changierhubes, möglich, wobei vorzugsweise die Exzenter 35, 36, 37 so eingestellt werden, daß niemals alle drei Reibwalzen 11, 12, 13 zum gleichen Zeitpunkt ihre Endlagen, d. h. ihre Umkehrpunkte, erreichen. Durch Buchstaben X, Y, Z in Fig. 3 ist eine bevorzugte Einstellage der drei Exzenter 35,36,37 angedeutet.As already mentioned, the shaft 32 arranged transversely to the shaft 20 is driven via the bevel drive 31. The shaft 32 is supported on both sides by means of stationary plates 33, 34. As can best be seen in FIGS. 2 and 4, an eccentric 35 is arranged on the left end of the shaft 32 and an eccentric 36 on the right end of the shaft as well as an eccentric 37 next to it. By loosening the respective fastening means, for example a conventional fixing screw, each of the eccentrics 35, 36, 37 can be rotated on the shaft 32. Due to the position of the eccentrics 35, 36, 37 on the shaft 32, an individual temporal influence on the traversing movement, i. H. to the phase position of the traversing stroke, possible, preferably the eccentrics 35, 36, 37 are set so that never all three friction rollers 11, 12, 13 their end positions at the same time, i. H. their turning points. A preferred setting position of the three eccentrics 35, 36, 37 is indicated by the letters X, Y, Z in FIG. 3.

Auf den Exzentern 35, 36, 37 sitzen Lager 38, 39, 40, auf denen jeweils ein Schwinghebel 41, 42, 43 aufgezogen ist. Wie die Fig. 2 und 4 erkennen lassen, ist der Schwinghebel 42 gekröpft, da die Reibwalzen 12, 13 übereinander angeordnet sind.Bearings 38, 39, 40 sit on the eccentrics 35, 36, 37, on each of which a rocker arm 41, 42, 43 is mounted. As can be seen in FIGS. 2 and 4, the rocker arm 42 is cranked since the friction rollers 12, 13 are arranged one above the other.

Fig. 2 läßt am besten erkennen, daß an jedem der Schwinghebel 41, 42 und 43 ein Zapfen 46, 47 und 48 befestigt ist, der jeweils einen der bereits erwähnten Gleitsteine 28, 29, 30 trägt.Fig. 2 shows best that on each of the rocker arms 41, 42 and 43 a pin 46, 47 and 48 is attached, each of which carries one of the sliding blocks 28, 29, 30 already mentioned.

Durch die vom Plattenzylinder 5 eingeleitete Rotation der Welle 32 und somit der Exzenter 35, 36, 37 wird durch die Schwinghebel 41, 42, 43 eine in Achsrichtung der Reibwalzen 11 bis 13 hin- und hergehende Bewegung erzeugt, die über Gleitsteine 28, 29, 30 auf die Achsstummel 22, 23, 24 der Reibwalzen 11, 12, 13 übertragen wird. Dadurch werden die in den Maschinenseitenwänden, von denen lediglich in den Fig. 3 und 4 die Maschinenseitenwand 21 angedeutet ist, gelagerten Reibwalzen 11, 12 und 13 in Axialrichtung hin- und herbewegt. Das Zentralzahnrad 16 ist wesentlich breiter als die Antriebszahnräder 11', 12' und 13', um auch einen sicheren Rotationsantrieb in allen Lagen sicherzustellen.Due to the rotation of the shaft 32 initiated by the plate cylinder 5 and thus the eccentric 35, 36, 37, the rocking levers 41, 42, 43 produce a reciprocating movement in the axial direction of the friction rollers 11 to 13, which movement is carried out via sliding blocks 28, 29, 30 is transmitted to the stub axles 22, 23, 24 of the friction rollers 11, 12, 13. As a result, the friction rollers 11, 12 and 13 mounted in the machine side walls, of which the machine side wall 21 is only indicated in FIGS. 3 and 4, are moved back and forth in the axial direction. The central toothed wheel 16 is considerably wider than the drive toothed wheels 11 ', 12' and 13 'in order to also ensure a reliable rotation drive in all positions.
