Definitions
- the invention relates to an inking unit of a printing press with an oscillating, rotation-driven friction roller as a drive for a circumferential, likewise oscillating and rotation-driven applicator roller, the drive being effected via a lever which is pivotably mounted on both rollers and on which a pivot axis is formed between the two bearings.
- Such inking units with oscillating application rollers which are axially displaced by the axial lifting movement of the distribution roller without a separate oscillation drive and are simultaneously driven to rotate by the distribution roller, have become known in numerous embodiments.
- a complicated gear is provided for the drive from the friction roller to the applicator roller.
- this is only possible when the machine is at a standstill and the conversion requires a noticeable amount of work, combined with a corresponding downtime of the machine.
- the invention avoids these disadvantages. It is based on the task of an inking unit with the features mentioned at the beginning to propose in which the traversing stroke is infinitely adjustable, even while the machine is running and possibly without trial prints.
- the invention is characterized in that the position of the pivot axis between the two bearings is adjustable.
- the position of the pivot axis between the two bearings of the lever on the two rollers thus determines the transmission ratio of the drive between zero and a maximum value.
- This position of the swivel axis can also be adjusted during operation of the machine by means of a suitable mechanism, so that the operator can, depending on the respective print image, adjust the distributor stroke while the machine is running, so that unusually little waste arises. This adjustment is infinitely possible and can therefore be done very sensitively.
- the friction roller and the applicator roller move in opposite directions, so that a double stroke is set at a transmission ratio of 1: 1, which may also have advantages. As mentioned, the stroke can be continuously adjusted from zero to a maximum.
- An important embodiment is characterized in that the position of the pivot axis of the lever is motor-controlled controlled by a scanner of the inking unit.
- the scanner of the inking unit has a subroutine that determines the necessity and the size of the stroke for the application roller and passes this data on to an adjustment gear.
- This arrangement results in a significant reduction in set-up times.
- a decision as to whether and how large the lateral rubbing stroke must be can only be made after the trial prints to be hit.
- the size of the stroke of the applicator roller cannot be changed while the machine is running.
- a machine stop during the printing process always means a disturbance of the ink / water balance and thus fluctuations in the printing and thus an increased amount of waste.
- a constructive embodiment of the invention is characterized in that a bearing forming the pivot axis of the lever is adjustable in a slot of the lever via a driven spindle. You turn the spindle in one direction or the other and this causes a nut sitting on the spindle to move in the slot in one direction or the other, which results in the desired setting of the pivot axis of the lever.
- a friction roller 1 is axially displaced in the direction of the double arrow 2 in its bearings indicated at position 3 via a drive, not shown. At the same time, the friction roller is driven to rotate.
- An applicator roller 4 bears against the friction roller. This should also be shifted axially via a drive to be described in more detail. A bearing of the applicator roller is indicated at position 5. It should be mentioned that the applicator roller is also driven to rotate by the friction roller because the two rollers abut against each other.
- the drive essentially consists of a lever 6, the ends of which are pivotally mounted both on the shaft of the friction roller 1 and on the shaft of the applicator roller 4.
- a roller is attached to both ends of the lever, which engages between rings on the shafts of the roller in question in such a way that the lever can be pivoted in the paper plane of Fig. 1 without the relevant shaft of the roller 1 or 4 on this to take an arched path.
- the lever has a pivot axis 8.
- the lever thus acts as a two-armed lever which can be pivoted about the axis 8 in the direction of arrow 9 in the plane of FIG. 1.
- the lever 6 is pivoted clockwise and the application roller 4 is thereby moved to the left into the dashed line Position axially shifted in Fig. 1.
- the pivot axis 8 is located centrally between the two pivot bearings 7, 7, then the displacement path 10 of the friction roller 1 corresponds to the displacement path 21 of the applicator roller 4.
- the ratio of these displacement paths can be adjusted, however, and all that is required is the position of the pivot axis 8 along the Adjust lever 6 accordingly. If the pivot axis 8 is at the location of the lower pivot bearing 7, the stroke of the application roller 4 is zero.
- the pivot axis 8 is in the vicinity of the upper pivot bearing 7, the maximum stroke 21 of the application roller 4 is present.
- Fig. 2 shows details of this drive with adjustment mechanism. It should be mentioned that in Fig. 2 the friction roller and the application roller are only indicated in their cores; in reality, their circumferences abut one another, as can be seen from FIG. 1.
- a spindle 11, on which a spindle nut 12 sits, which is extended downward to the bearing 18 of the pivot axis 8, serves for the drive for adjusting the pivot axis 8. If the spindle in its bearing 13 is rotated in one or the other direction of rotation, the nut 12 moves in the direction of the arrow 14 and thus also the bearing 18, which runs in an elongated hole 15 of the lever 6.
- the bearing 7 engaging on the friction roller 1 is designed as a spherical bearing in order to prevent any occurring during adjustment Being able to pick up canting.
- the lower bearing 7 is equipped with a driving roller 16.
- the rollers 1 and 4 are axially displaced as a whole in their bearings 3 and 5 and a separation of the applicator roller 4 into a shaft and into an axially displaceable jacket, as is also chosen as a solution in the prior art, is not necessary . It can thus be seen that the stroke of the applicator roller 4 can, if desired, be made stronger than that of the friction roller 1, depending on where the pivot axis 8 of the lever 6 is placed. If the swivel axis is in the middle, the stroke is doubled. This increased stroke thus results in even smoother transitions between more and less color on the printed image.
- An already existing scanner determines the necessity and the size of the stroke for the application roller in a subroutine. This data is forwarded to the adjustment gear. There they are converted, for example, into a corresponding rotation of the spindle 11 or also into the actuation of another drive for the adjustment of the swivel axis 8.
- the friction stroke can thus be set immediately by motor via the scanner data, in a motorized fine adjustment from the control panel. This is also a great advantage compared to the known systems, in which the stroke can only be adjusted on the roller itself.

Abstract
Description
Die Erfindung betrifft ein Farbwerk einer Druckmaschine mit einer changierenden, auf Drehung angetriebenen Reibwalze als Antrieb für eine an ihrem Umfang anliegende, ebenfalls changierende und auf Drehung angetriebene Auftragwalze, wobei der Antrieb über einen Hebel erfolgt, der an beiden Walzen schwenkbar gelagert ist und an dem zwischen den beiden Lagern eine Schwenkachse ausgebildet ist.The invention relates to an inking unit of a printing press with an oscillating, rotation-driven friction roller as a drive for a circumferential, likewise oscillating and rotation-driven applicator roller, the drive being effected via a lever which is pivotably mounted on both rollers and on which a pivot axis is formed between the two bearings.
Derartige Farbwerke mit changierenden Auftragwalzen, die ohne gesonderten Changierantrieb durch die axiale Hubbewegung der Reibwalze axial verschoben und gleichzeitig durch die Reibwalze auf Drehung angetrieben werden, sind in zahlreichen Ausführungsformen bekannt geworden. Als Beispiel sei verwiesen auf die DE-PS 36 38 826, von der die Erfindung ausgeht. Hier ist ein kompliziertes Getriebe für den Antrieb von der Reibwalze auf die Auftragwalze vorgesehen. Dort muß man Lagerhülsen verdrehen, wenn man den Hub verändern will. Dies ist aber nur bei stillstehender Maschine möglich und der Umbau erfordert einen fühlbaren Arbeitsaufwand, verbunden mit einer entsprechenden Stillstandzeit der Maschine. Auch ist dies konstruktiv aufwendig, insbesondere weil mit jeder Stellung der Lagerhülsen Anschlagklötze mit Nuten und Rastkugeln in gesonderter Weise zusammenwirken müssen, um die gewünschte Verstellung des Hubs zu bewirken. Als weiterer Nachteil kommt hinzu, daß dort der Hub nur stufenweise verstellt werden kann, beispielsweise kann er halbiert werden.Such inking units with oscillating application rollers, which are axially displaced by the axial lifting movement of the distribution roller without a separate oscillation drive and are simultaneously driven to rotate by the distribution roller, have become known in numerous embodiments. As an example, reference is made to DE-PS 36 38 826, from which the invention is based. Here a complicated gear is provided for the drive from the friction roller to the applicator roller. There you have to twist bearing sleeves if you want to change the stroke. However, this is only possible when the machine is at a standstill and the conversion requires a noticeable amount of work, combined with a corresponding downtime of the machine. This is also structurally complex, in particular because with each position of the bearing sleeves, stop blocks with grooves and locking balls have to interact in a separate manner in order to bring about the desired adjustment of the stroke. Another disadvantage is that the stroke can only be adjusted in stages, for example it can be halved.
Ein Farbwerk mit den eingangs genannten Merkmalen ist in der DE-C-139 802 beschrieben. Die Lage der Schwenkachse ist dort nicht verstellbar. Damit kann der Changierhub auch nicht während des Maschinenlaufs eingestellt werden.An inking unit with the features mentioned at the outset is described in DE-C-139 802. The position of the swivel axis is not adjustable there. This means that the traversing stroke cannot be set while the machine is running.
Die Erfindung vermeidet diese Nachteile. Ihr liegt die Aufgabe zugrunde, ein Farbwerk mit den eingangs genannten Merkmalen vorzuschlagen, bei dem der Changierhub stufenlos einstellbar ist, und zwar auch während des Maschinenlaufs und ggf. ohne Probeabzüge.The invention avoids these disadvantages. It is based on the task of an inking unit with the features mentioned at the beginning to propose in which the traversing stroke is infinitely adjustable, even while the machine is running and possibly without trial prints.
Zur Lösung dieser Aufgabe ist die Erfindung dadurch gekennzeichnet, daß die Lage der Schwenkachse zwischen den beiden Lagern verstellbar ist.To achieve this object, the invention is characterized in that the position of the pivot axis between the two bearings is adjustable.
Die Lage der Schwenkachse zwischen den beiden Lagern des Hebels an den beiden Walzen bestimmt somit das Übersetzungsverhältnis des Antriebs zwischen Null und einem maximalen Wert. Diese Lage der Schwenkachse kann über einen geeigneten Mechanismus auch während des Betriebs der Maschine eingestellt werden, so daß die Bedienungsperson, abhängig vom jeweiligen Druckbild, den Verreiberhub beim Maschinenlauf verstellen kann, so daß ungewöhnlich wenig Makulatur entsteht. Diese Verstellung ist stufenlos möglich und kann daher sehr feinfühlig erfolgen. Außerdem bewegen sich die Reibwalze und die Auftragwalze gegenläufig, so daß bei einem Übersetzungsverhältnis von 1 : 1 ein doppelter Hub eingestellt wird, was ggf. ebenfalls Vorteile mit sich bringt. Wie erwähnt kann der Hub aber von Null bis zu einem Maximum stufenlos eingestellt werden.The position of the pivot axis between the two bearings of the lever on the two rollers thus determines the transmission ratio of the drive between zero and a maximum value. This position of the swivel axis can also be adjusted during operation of the machine by means of a suitable mechanism, so that the operator can, depending on the respective print image, adjust the distributor stroke while the machine is running, so that unusually little waste arises. This adjustment is infinitely possible and can therefore be done very sensitively. In addition, the friction roller and the applicator roller move in opposite directions, so that a double stroke is set at a transmission ratio of 1: 1, which may also have advantages. As mentioned, the stroke can be continuously adjusted from zero to a maximum.
Eine wichtige Ausgestalung wird dadurch gekennzeichnet, daß die Lage der Schwenkachse des Hebels von einem Scanner des Farbwerks gesteuert motorisch verstellbar ist. Der Scanner des Farbwerks hat hierzu ein Unterprogramm, das die Notwendigkeit und die Größe des Hubs für die Auftragwalze ermittelt und diese Daten an ein Verstellgetriebe weitergibt. Durch diese Anordnung tritt eine wesentliche Verkürzung der Rüstzeiten auf. Bei bekannten Systemen kann eine Entscheidung, ob und wie groß der seitliche Verreibungshub sein muß, erst nach den Probeabzügen getroffen werden. Ferner kann während des Maschinenlaufs keine Veränderung der Größe des Hubs der Auftragwalze vorgenommen werden. Ein Maschinenstop während des Fortdruckens bedeutet immer eine Störung des Gleichgewichts Farbe/Wasser und damit Schwankungen im Druck und somit einen erhöhten Makulaturanfall. Auch diese Nachteile werden durch die genannte Vorrichtung beseitigt.An important embodiment is characterized in that the position of the pivot axis of the lever is motor-controlled controlled by a scanner of the inking unit. For this purpose, the scanner of the inking unit has a subroutine that determines the necessity and the size of the stroke for the application roller and passes this data on to an adjustment gear. This arrangement results in a significant reduction in set-up times. In known systems, a decision as to whether and how large the lateral rubbing stroke must be can only be made after the trial prints to be hit. Furthermore, the size of the stroke of the applicator roller cannot be changed while the machine is running. A machine stop during the printing process always means a disturbance of the ink / water balance and thus fluctuations in the printing and thus an increased amount of waste. These disadvantages are also eliminated by the device mentioned.
Eine konstruktive Ausgestaltung der Erfindung ist dadurch gekennzeichnet, daß ein die Schwenkachse des Hebels ausbildendes Lager in einem Langloch des Hebels über eine angetriebene Spindel verstellbar ist. Man dreht die Spindel in der einen oder anderen Richtung und dadurch wandert eine auf der Spindel sitzende Mutter im Langloch in der einen oder anderen Richtung, wodurch sich die gewünschte Einstellung der Schwenkachse des Hebels ergibt.A constructive embodiment of the invention is characterized in that a bearing forming the pivot axis of the lever is adjustable in a slot of the lever via a driven spindle. You turn the spindle in one direction or the other and this causes a nut sitting on the spindle to move in the slot in one direction or the other, which results in the desired setting of the pivot axis of the lever.

Zunächst sei anhand von Fig. 1 der grundsätzliche Aufbau und die grundsätzliche Wirkungsweise der erfindungsgemäßen Vorrichtung näher erläutert.First, the basic structure and the principle of operation of the device according to the invention will be explained in more detail with reference to FIG. 1.
Eine Reibwalze 1 wird über einen nicht gezeigten Antrieb in Richtung des Doppelpfeils 2 axial in ihren bei Position 3 angedeuteten Lagern verschoben. Gleichzeitig wird die Reibwalze auf Drehung angetrieben.A friction roller 1 is axially displaced in the direction of the
An der Reibwalze liegt eine Auftragwalze 4 an. Diese soll über einen noch näher zu beschreibenden Antrieb ebenfalls axial verschoben werden. Ein Lager der Auftragwalze ist bei Position 5 angedeutet. Es sei erwähnt, daß die Auftragwalze von der Reibwalze auch auf Drehung angetrieben wird, weil beide Walzen aneinander anliegen.An applicator roller 4 bears against the friction roller. This should also be shifted axially via a drive to be described in more detail. A bearing of the applicator roller is indicated at
Der Antrieb besteht im wesentlichen aus einem Hebel 6, dessen Enden sowohl an der Welle der Reibwalze 1 wie auch an der Welle der Auftragwalze 4 schwenkbar gelagert sind. Hierzu ist an beiden Enden des Hebels eine Rolle befestigt, die zwischen Ringe an den Wellen der betreffenden Walze eingreift derart, daß der Hebel in der Papierebene von Fig. 1 verschwenkt werden kann, ohne dabei die betreffende Welle der Walze 1 bzw. 4 auf dieser bogenförmigen Bahn mitzunehmen.The drive essentially consists of a
Zwischen den beiden so ausgebildeten Schwenklagern 7 an den Enden des Hebels 6 hat der Hebel eine Schwenkachse 8. Der Hebel wirkt also als zweiarmiger Hebel, der in der Ebene von Fig. 1 um die Achse 8 in Pfeilrichtung 9 verschwenkt werden kann.Between the two
Wird beispielsweise die Reibwalze 1 in Fig. 1 nach rechts in die gestrichelt angedeutete Position verschwenkt, so wird dabei der Hebel 6 im Uhrzeigersinn verschwenkt und dadurch wird die Auftragwalze 4 nach links in die gestrichelte Position in Fig. 1 axial verschoben. Wenn sich die Schwenkachse 8 mittig zwischen den beiden Schwenklagern 7, 7 befindet, so entspricht der Verschiebungsweg 10 der Reibwalze 1 dem Verschiebungsweg 21 der Auftragwalze 4. Das Verhältnis dieser Verschiebungswege kann man aber einstellen und hierzu muß man lediglich die Lage der Schwenkachse 8 längs des Hebels 6 entsprechend verstellen. Befindet sich die Schwenkachse 8 am Ort des unteren Schwenklagers 7, so ergibt sich ein Hub der Auftragwalze 4 gleich Null. Befindet sich die Schwenkachse 8 dagegen in der Nähe des oberen Schwenklagers 7, so liegt der maximale Hub 21 der Auftragwalze 4 vor. Durch eine entsprechende Einstellung der Schwenkachse 8 längs des Hebels 6 kann also das Übersetzungsverhältnis und damit den Hub der Auftragwalze in Bezug auf die Reibwalze eingestellt werden.If, for example, the friction roller 1 in FIG. 1 is pivoted to the right into the position indicated by the dashed line, the
Fig. 2 zeigt Einzelheiten dieses Antriebs mit Verstellmechanismus. Es sei erwähnt, daß in Fig. 2 die Reibwalze und die Auftragwalze nur in ihren Kernen angedeutet sind; in Wirklichkeit liegen sie mit ihren Umfängen aneinander an, wie aus Fig. 1 ersichtlich.Fig. 2 shows details of this drive with adjustment mechanism. It should be mentioned that in Fig. 2 the friction roller and the application roller are only indicated in their cores; in reality, their circumferences abut one another, as can be seen from FIG. 1.
Für den Antrieb zum Verstellen der Schwenkachse 8 dient eine Spindel 11, auf der eine Spindelmutter 12 sitzt, die nach unten zu dem Lager 18 der Schwenkachse 8 verlängert ist. Wird die Spindel in ihrem Lager 13 in der einen oder anderen Drehrichtung gedreht, so wandert die Mutter 12 in Richtung des Pfeiles 14 und damit entsprechend auch das Lager 18, das in einem Langloch 15 des Hebels 6 läuft.A
Das an der Reibwalze 1 angreifende Lager 7 ist als sphärisches Lager ausgebildet, um beim Verstellen auftretende Verkantungen aufnehmen zu können. Aus demselben Grunde ist das untere Lager 7 mit eine Mitnehmerrolle 16 ausgerüstet.The bearing 7 engaging on the friction roller 1 is designed as a spherical bearing in order to prevent any occurring during adjustment Being able to pick up canting. For the same reason, the
Die Walzen 1 und 4 werden als Ganzes in ihren Lagern 3 bzw. 5 axial verschoben und eine Trennung der Auftragwalze 4 in eine Welle und in einen dazu axial dazu verschiebbaren Mantel, wie dies ebenfalls beim Stand der Technik als Lösung gewählt wird, ist nicht notwendig.
Es ist somit ersichtlich, daß der Hub der Auftragwalze 4 gewünschtenfalls stärker ausgebildet werden kann als derjenigen der Reibwalze 1, jenachdem, wo die Schwenkachse 8 des Hebels 6 plaziert wird. Befindet sich die Schwenkachse mittig, so wird der Hub verdoppelt. Dieser verstärkte Hub ergibt somit noch sanftere Übergänge zwischen mehr und weniger Farbe auf dem Druckbild.The rollers 1 and 4 are axially displaced as a whole in their
It can thus be seen that the stroke of the applicator roller 4 can, if desired, be made stronger than that of the friction roller 1, depending on where the pivot axis 8 of the
Ein ohnedies vorhandener Scanner ermittelt in einem Unterprogramm die Notwendigkeit und die Größe des Hubs für die Auftragwalze. Diese Daten werden an das Verstellgetriebe weitergeleitet. Dort werden sie beispielsweise in eine entsprechende Drehung der Spindel 11 umgesetzt oder auch in die Betätigung eines anderen Antriebs für die Verstellung der Schwenkachse 8. Der Verreibungshub kann also über die Scannerdaten sofort motorisch eingestellt werden, und zwar in einer motorischen Feineinstellung vom Bedienpult aus. Auch dies ist, verglichen mit den bekannten Systemen, ein großer Vorteil, bei denen der Hub nur an der Walze selbst verstellt werden kann.An already existing scanner determines the necessity and the size of the stroke for the application roller in a subroutine. This data is forwarded to the adjustment gear. There they are converted, for example, into a corresponding rotation of the
In Fig. 1 sind die beiden aus Fig. 2 ersichtlichen Langlöcher, die sich um die beiden Schwenklagerachsen 7 erstrecken, zur Vereinfachung zeichnerisch nicht dargestellt.In Fig. 1, the two elongated holes shown in Fig. 2, which extend around the two
