Abstract

A mechanism for axially reciprocating at least one of the distributing rollers of a printing press. A rocker having an elongated slot therein is mounted on a first pivot and oscillated thereabout by means of a link eccentrically connected to the press drive shaft. An oscillating lever is pivotally connected to the press frame for movement about a second pivot and includes a sliding block captively held in the elongated slot of the rocker. The oscillating lever is operatively connected to at least one of the distributing rollers so as to axially reciprocate the roller in response to the oscillation of the lever. The location of the first pivot is adjustable with respect to the press frame so as to change the orientation of the elongated slot in the rocker and, thus, vary the magnitude of travel of the oscillating lever which reciprocates the distributing roller. For such purpose, the first pivot is secured in one arm of a two-armed lever, the lever being pivotally connected to the frame. The second arm of the lever is secured to a traveling nut which is threaded on a shaft mounted for rotational movement with respect to the frame. Either a manually turnable knob or an electric motor is connected to the shaft so as to rotate the same, resulting in a rotation of the two-armed lever about its pivot to change the position of the first pivot held in the first arm of the lever.

Description

Vorrichtung zum Verändern des Hubes einer axial hin- und herbewegbaren Verreibwalze, bei der der Antrieb von einer Druckmaschinenwelle über eine Kurbel und eine Koppel auf einen Schwenkhebel übertragen wird, wobei zwischen Schwenkhebel und Koppel eine Schwinge angeordnet ist, die durch ein Gleitgelenk mit dem Schwenkhebel gelenkig verbunden ist.Device for changing the stroke of an axially reciprocating distributor roller, in which the drive is transmitted from a printing press shaft via a crank and a coupling to a pivoting lever, a rocker being arranged between the pivoting lever and the coupling, which is articulated by a sliding joint with the pivoting lever connected is.

Eine Vorrichtung dieser Gattung ist durch die GB-A 888 611 bekannt. Bei dieser Vorrichtung ist keine kontinuierliche Hubverstellung während des Maschinenlaufs möglich. Im Offset-Druckmaschinenbau ist es bekannt, Verreibwalzen vorzusehen, die sich axial hin- und herbewegen. Diese Verreibwalzen sollen die Farbe gleichmäßig auf die Übertragswalzen verteilen.A device of this type is known from GB-A 888 611. With this device, continuous stroke adjustment is not possible while the machine is running. In offset printing machine construction, it is known to provide distribution rollers that move axially back and forth. These distribution rollers are intended to distribute the ink evenly over the transfer rollers.

Um die Hin- und Herbewegung der Verreibwalzen ausführen zu können, sind die unterschiedlichsten Ausführungen bekannt geworden.In order to be able to carry out the back and forth movement of the distribution rollers, a wide variety of designs have become known.

In der DE-OS 2 238 481 ist ein Antrieb für eine gleichzeitige dreh- sowie hin- und herbewegbare Verreibwalze an Druckmaschinen bekannt geworden. Diesem Antrieb liegt die Aufgabe zugrunde, die Verreiberbewegung mit Innensteuerung zu verlangsamen, so daß die Vorteile der Innensteuerung ohne die Nachteile eines schnellen Ablaufes der Axialbewegung genutzt werden können.In DE-OS 2 238 481 a drive for a simultaneous rotating and reciprocating distributor roller on printing machines has become known. This drive is based on the task of slowing down the displacement movement with the internal control so that the advantages of the internal control can be used without the disadvantages of a rapid course of the axial movement.

In der Bedienungsanleitung Roland Rekord ist auf Seite 270 eine Verreibung dargestellt, die seitlich bzw. axial zur Verreibwalze von 0 bis zu einem maximalen Hub regulierbar ist. Zum Verstellen des Hubes ist ein Klappdeckel auf der Antriebsseite der Druckmaschine zu öffnen und eine Klemmschraube durch Verschieben des Antriebspunktes in einer Nut zu verändern. Je weiter der Antriebspunkt zur Mitte verschoben wird, umso geringer ist der Hub der Verreibwalzen.On page 270 of the Roland Rekord operating instructions, an attrition is shown that can be adjusted laterally or axially to the distributing roller from 0 to a maximum stroke. To adjust the stroke, open a hinged cover on the drive side of the printing press and change a clamping screw by moving the drive point in a groove. The farther the drive point is shifted to the center, the smaller the stroke of the distributor rollers.

Der Verreibungseinsatz ist hierbei vom Werk in der Normalstellung so eingestellt, daß das Ziehen der VerreibwaJzen beginnt, wenn der Druckanfang des Plattenzylinders bei der zweiten Auftragwalze steht. Der Verreibungseinsatz wird bei speziellen Druckbildern verändert, bei denen in Laufrichtung der Zylinderachse große Farbdichteunterschiede auftreten.The trituration insert is set in the factory in the normal position so that the trituration rollers start to pull when the printing start of the plate cylinder is at the second applicator roller. The use of rubbing is changed for special printed images in which there are large color density differences in the direction of the cylinder axis.

Bei diesen bekannten Vorrichtungen muß die Druckmaschine jeweils abgestellt werden, um den Verreibungshub verstellen zu können. Dies bedeutet jeweils eine bestimmte Rüst- bzw. Montierzeit und eine erhebliche Anzahl Makulaturbögen, bevor der für jedes Druckbild erforderliche optimale Verreibungshub eingestellt ist.In these known devices, the printing press must be switched off in order to be able to adjust the distribution stroke. This means a certain set-up or assembly time and a considerable number of waste sheets before the optimal rubbing stroke required for each print image is set.

Auch noch bei Fortdruck kann Makulatur entstehen, wenn sich herausstellt, daß der Verreibungshub durch bestimmte Parameter der Druckmaschine verändert werden muß, so z.B. durch die Temperatureinflüsse während des Druckes.Waste can also arise during production if it turns out that the rubbing stroke has to be changed by certain parameters of the printing press, e.g. due to the temperature influences during printing.

Spezielle Anforderungen an den Verreibungshub sind bekanntermaßen bei einem Irisdruck gegeben. Hierbei ist es besonders günstig, den Verreibungshub wahlweise verstellen zu können um die jeweils sich vom Druckbild ergebenden fließenden Übergänge direkt einstellen zu können.As is known, there are special requirements for the rubbing stroke with an iris print. It is particularly advantageous here to be able to optionally adjust the distribution stroke in order to be able to directly set the flowing transitions that result from the printed image.

Um bei den bekannten Vorrichtungen den Verreibungshub verstellen zu können, muß jeweils die Druckmaschine abgestellt sein. Diese Einstellungsweise hat aber den wesentlichen Nachteil, bedingt durch die Stillstandszeit der Druckmaschine, daß Farbschwankungen und Störungen des Farb-Wasser-Gleichgewichtes sowie daraus resultierende Beurteilungsfehler der Druckbögen die Folge sind.In order to be able to adjust the distribution stroke in the known devices, the printing machine must be turned off in each case. However, this setting method has the major disadvantage, due to the downtime of the printing press, that color fluctuations and disturbances in the ink-water balance as well as the resulting assessment errors of the printed sheets are the result.

Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde, in Abhängigkeit vom Druck, bzw. Druckbild und dem Fortdruck eine stufenlose Hubverstellung während des Maschinenlaufes unter minimalem Makulaturanfall zu erreichen.Proceeding from this prior art, the object of the invention is to achieve a stepless stroke adjustment while the machine is running with minimal waste, depending on the print or printed image and the production run.

Die Lösung der gestellten Aufgabe wird bei einer Vorrichtung der Eingangs genannten Art erfindungsgemäß dadurch erreicht, daß die Schwinge in dem einen Arm eines doppelarmigen Gabelhebels gelagert ist, an dessen anderem Arm eine Gewindespindel so angreift, daß zur Verstellung des Hubes durch Verdrehen der Gewindespindel die Lage des Gleitgelenks auf der Schwinge bzw. auf dem Schwenkhebel veränderbar ist.The solution of the problem is achieved in a device of the type mentioned according to the invention in that the rocker is mounted in one arm of a double-armed fork lever, on the other arm a threaded spindle engages so that the position by adjusting the stroke by turning the threaded spindle the sliding joint on the rocker or on the swivel lever is changeable.

Das Verändern des Hubes während des Maschinenlaufes verkürzt die Rüstzeit bzw. Maschineneinstellzeit für den Drucker wesentlich, da die jeweilig erforderlichen Umstellarbeiten zu keinem Abschalten der Druckmaschine führen und damit wesentlich vereinfacht sind.Changing the stroke while the machine is running significantly shortens the set-up time or machine setting time for the printer, since the changeover work required in each case does not result in the printing machine being switched off and is therefore considerably simplified.

Die Vorrichtung ist in das obere und untere Farbwerk einer Druckmaschine gleichermaßen einsetzbar.The device can be used equally in the upper and lower inking units of a printing press.

Da das Vergleichen von Probebögen während des Druckes erfolgt, ist der Makulaturanfall minimal. Das Nachregeln des Hubes der Verreibwalzen kann sofort direkt nach dem Vergleich vorgenommen werden, was einem weiteren minimalen Makulaturanfall entspricht.Since the comparison of test sheets takes place during printing, the amount of waste is minimal. The adjustment of the stroke of the distribution rollers can be carried out immediately after the comparison, which corresponds to a further minimal amount of waste.

Das Verändern des Hubes kann besonders einfach mit einem Handgriff während des Maschinenlaufes durchgeführt werden. Der Handgriff weist hierzu eine Skaleneinteilung auf, so daß der Drucker jeweils bei ähnlichen Druckaufträgen die Skala nach dem bekannten Druckbild einstellen kann.Changing the stroke can be carried out particularly easily with one hand while the machine is running. For this purpose, the handle has a scale division, so that the printer can set the scale according to the known printed image for similar print jobs.

In besonders vorteilhafter Weise kann eine automatische ferngesteuerte Verreibungshubeinstellung mittels eines elektrischen Motors vorgenommen werden. Denkbar ist hierbei ein Einspielen der entsprechend kodierten Stellungswerte auf ein Band, was zu einem leichten Einstellvorgang bei Wiederholungsaufträgen führt.In an especially advantageous manner, an automatic remote-controlled friction stroke adjustment can be carried out by means of an electric motor. It is conceivable here to import the correspondingly coded position values onto a tape, which leads to an easy adjustment process for repeat jobs.

Zwischen einem Schwenkhebel und einer Koppel ist eine Schwinge angeordnet, die durch ein Gleitgelenk mit dem Schwenkhebel gelenkig verbunden ist. Damit kann die Hubverstellung der Verreibwalzen innerhalb der Druckmaschine mit minimalen Maschinenelementen verändert werden. Die unterschiedlichsten Hubbewegungen sind vom Handrad oder vom Motor über einen Gabelhebel auf die Schwinge einstellbar.A swing arm is arranged between a swivel lever and a coupling a sliding joint is pivotally connected to the swivel lever. The stroke adjustment of the distribution rollers within the printing press can thus be changed with minimal machine elements. A wide variety of lifting movements can be adjusted from the handwheel or the motor to the rocker using a fork lever.

Weitere Vorteile und wesentliche Merkmale der Erfindung gehen aus den Unteransprüchen und der folgenden Beschreibung in Verbindung mit den schematisch im Schnitt gezeigten Ausführungsbeispielen hervor.Further advantages and essential features of the invention emerge from the subclaims and the following description in conjunction with the exemplary embodiments shown schematically in section.

Es zeigt:

  • Fig. 1 eine Seitenansicht eines Teilsausschnittes einer Druckmaschine im Bereich der Verreibwalzen und deren Antriebsverstellung,
  • Fig. 2 eine ähnliche Darstellung wie in Fig. 1, bei der ein elektrischer Motor anstelle eines Handgriffes eingesetzt ist,
  • Fig. 3 eine Detailansicht der miteinander in Eingriff stehenden Maschinenelemente, die die Hubverstellung der Verreibwalzen ermöglicht.
It shows:
  • 1 is a side view of a partial section of a printing press in the area of the distribution rollers and their drive adjustment,
  • FIG. 2 shows a representation similar to that in FIG. 1, in which an electric motor is used instead of a handle,
  • Fig. 3 is a detailed view of the engaging machine elements, which enables the stroke adjustment of the distribution rollers.

Fig. 1 zeigt mehrere Verreibwalzen 1 einer nicht näher dargestellten Druckmaschine 4. Um den Hub 2 der Verreibwalzen 1 während des Laufes der Druckmaschine 4 verstellen zu können, ist an einer Maschinenbedienungsseite 16 ein Handgriff 15 in Griffhöhe des Druckers angeordnet. Auf der Innenseite der Druckmaschine 4 geht der Handgriff 15 in eine Gewindespindel 9 über, welche einen Gewindeführungsbolzen 8 in axialer Richtung der Gewindespindel 9 durch Drehen des Handgriffes 15 zu verstellen ermöglicht. Der Gewindeführungsbolzen 8 ist in einer Nut 7.1 eines zweiarmigen Gabelhebels 7 geführt. Am zweiten Hebelarm 7.2 des Gabelhebels 7 ist ein Gelenkbolzen 5 innerhalb einer Schwinge 5.1 drehbar befestigt. Die Schwinge 5.1 weist eine Nut 5.2 auf, in der ein Gleitgelenk 5.4 geführt ist. Am entgegengesetzten Ende vom Gelenkbolzen 5 ist an der Schwinge 5.1 ein Gelenkbolzen 3.2 befestigt, an dem eine Koppel 3.1 angreift. Die Koppel 3.1 ist an einer Kurbwel 3.3 angelenkt, die an einer Druckmaschinenwelle 3 befestigt ist. Die Druckmaschinenwelle 3 liefert hierbei den Antrieb für die axiale Hin- und Herbewegung der Verreibwalzen 1 über die oben genannten Maschinenelemente (3-11).1 shows a plurality of distribution rollers 1 of a printing machine 4, not shown in detail. In order to be able to adjust the stroke 2 of the distribution rollers 1 while the printing machine 4 is running, a handle 15 is arranged on the machine operating side 16 at handle height of the printer. On the inside of the printing press 4, the handle 15 merges into a threaded spindle 9, which enables a threaded guide pin 8 to be adjusted in the axial direction of the threaded spindle 9 by turning the handle 15. The thread guide pin 8 is guided in a groove 7.1 of a two-armed fork lever 7. On the second lever arm 7.2 of the fork lever 7, a hinge pin 5 is rotatably fastened within a rocker 5.1. The rocker 5.1 has a groove 5.2 in which a slide joint 5.4 is guided. At the opposite end of the hinge pin 5, a hinge pin 3.2 is attached to the rocker 5.1, on which a coupling 3.1 engages. The coupling 3.1 is articulated to a crank shaft 3.3 which is fastened to a printing machine shaft 3. The printing machine shaft 3 provides the drive for the axial back and forth movement of the distributor rollers 1 via the above-mentioned machine elements (3-11).

Innerhalb der Nut 5.2 der Schwinge 5.1 ist ein Nutenstein 5.3 gleitend gelagert, der auf einen Bolzen 6.2 aufgesteckt ist. Der Bolzen 6.2 ist an einem Schwenkhebel 6.1 fest fixiert. Der Schwenkhebel 6.1 dreht um einen Drehpunkt 6, der in einem Maschinenseitenständer, hier eine Halteplatte 18, befestigt ist. Der Schwenkhebel 6.1 und die Schwinge 5.1 führen parallel zueinander Schwenkbewegungen aus. Der Schwenkhebel 6.1 ist an seiner zweiten Seite über ein Mitnahmeelement 11 mit Verreibungshebeln 10.1 -10.3 verbunden. Die Verreibungshebel 10.1 - 10.3 sind einem Drehpunkt 10 fest innerhalb der Druckmaschine 4 gelagert. Die Verreibungshebel 10.1 - 10.3 übertragen durch ihre Drehbewegung die axiale Hubbewegung auf die Verreibwalzen 1. Um alle Verreibwalzen 1 der Druckmaschine 4 auf einfacheweise erreichen zu können, sind jeweils an entgegengesetzten Enden der Verreibwalzen 1 die Verreibungshebel 10.2 und 10.3 angeordnet.Within the groove 5.2 of the rocker 5.1, a sliding block 5.3 is slidably mounted, which is attached to a bolt 6.2. The bolt 6.2 is fixedly attached to a swivel lever 6.1. The pivot lever 6.1 rotates about a pivot point 6, which is fastened in a machine side stand, here a holding plate 18. The pivot lever 6.1 and the rocker 5.1 execute parallel pivoting movements. The pivot lever 6.1 is connected on its second side via a driving element 11 to the friction levers 10.1-10.3. The friction levers 10.1-10.3 are fixed to a fulcrum 10 within the printing press 4. The rubbing levers 10.1-10.3 transmit the axial lifting movement to the rubbing rollers 1 by their rotary movement. In order to be able to easily reach all the rubbing rollers 1 of the printing machine 4, the rubbing levers 10.2 and 10.3 are respectively arranged on opposite ends of the rubbing rollers 1.

Figur 2 zeigt den gleichen technischen Aufbau wie in Fig. 1 beschrieben, wobei aber anstatt des Handgriffes 15 ein elektrisch ansteuerbarer Motor 17 auf die Gewindespindel 9 wirkt.Figure 2 shows the same technical structure as described in Fig. 1, but instead of the handle 15, an electrically controllable motor 17 acts on the threaded spindle 9.

Figur 3 zeigt einen Teilausschnitt der Druckmaschine 4, mit der Hubverstellung durch den Handgriff 15. Vom Handgriff 15 ist in axialer Richtung die Gewindespindel 9 angeordnet, auf der sich der Gewindeführungsbolzen 8 befindet. D.urch Drehen am Handgriff 15 kann der Gewindeführungsbolzen 8 axial auf der Gewindespindel 9 verändert werden. Diese axiale Hubbewegung des Gewindeführungsbolzens 8 überträgt sich auf den Gabelhebel 7, wobei der Gewindeführungsbolzen 8 in der Nut 7.1 zwangsgeführt ist. Am zweiten Hebelarm 7.2 des Gabelhebels 7 ist der Gelenkbolzen 5 innerhalb der Schwinge 5.1 befestigt. Der Antrieb für die Verreibwalzen 1 erfolgt über die Koppel 3.1 auf die Schwinge 5.1. Verstellt sich der Gabelhebel 7, so muß die Relativbewegung zwischen der Schwinge 5.1 und dem Schwenkhebel 6.1 über das Gleitgelenk 5.4 innerhalb der Nut 5.2 der Schwinge 5.1 ausgeglichen werden. Das Gleitgelenk 5.4 ist in Form eines Nutensteines 5.3 ausgeführt. Der Schwenkhebel 6.1 führt eine drehende Hin- und Herbewegung um den Drehpunkt 6 aus. Die Größe der Hin- und Herbewegung des Schwenkhebels 6.1 richtet sich nach der Verstellgröße des Gabelhebels 7. Die Schwenkbewegung des Schwenkhebels 6.1 um den Drehpunkt 6 wird an der dem Drehpunkt 6 entgegengesetzten Seite des Schwenkhebels 6.1 auf ein Mitnahmeelement 11 übertragen, wobei das Mitnahmeelement 11 drehbar in einem Schulterlager 20 im Schwenkhebel 6.1 gelagert ist. Das Mitnahmeelement 11 überträgt hierbei die Bewegungen auf einen ersten Hebel 21 des Verreibungshebels 10.3, welcher im Drehpunkt 10 fest innerhalb der Druckmaschine 4 gelagert ist. Ein zweiter Hebel 22 des Verreibungshebels 10.3 wirkt auf die Verreibwalzen 1 und führen je nach Einstellung am Handgriff 15 zu einem unterschiedlich großen Hub 2 der Verreibwalzen 1.

 Figure 3 shows a partial section of the printing press 4, with the stroke adjustment by the handle 15. The threaded spindle 9 is arranged in the axial direction on the handle 15, on which the threaded guide pin 8 is located. By turning the handle 15, the threaded guide pin 8 can be changed axially on the threaded spindle 9. This axial stroke movement of the threaded guide pin 8 is transferred to the fork lever 7, the threaded guide pin 8 being positively guided in the groove 7.1. On the second lever arm 7.2 of the fork lever 7, the hinge pin 5 is fastened within the rocker 5.1. The drive for the distributor rollers 1 takes place via the coupling 3.1 on the rocker 5.1. If the fork lever 7 is adjusted, the relative movement between the rocker 5.1 and the rocker arm 6.1 must be compensated for via the slide joint 5.4 within the groove 5.2 of the rocker 5.1. The slide joint 5.4 is designed in the form of a sliding block 5.3. The pivot lever 6.1 executes a rotating back and forth movement about the pivot point 6. The size of the back and forth movement of the pivot lever 6.1 depends on the adjustment size of the fork lever 7. The pivot movement of the pivot lever 6.1 about the pivot point 6 is transmitted to a driving element 11 on the side of the pivot lever 6.1 opposite the pivot point 6, the driving element 11 being rotatable is mounted in a shoulder bearing 20 in the pivot lever 6.1. The entrainment element 11 transmits the movements to a first lever 21 of the friction lever 10.3, which is fixed in the fulcrum 10 within the printing press 4. A second lever 22 of the distribution lever 10.3 acts on the distribution rollers 1 and, depending on the setting on the handle 15, leads to a differently large stroke 2 of the distribution rollers 1.
