Description

Die Erfindung betrifft einen verschwenkbaren Farbmesserträger in Rotationsdruckmaschinen gemäß dem Oberbegriff des Patentanspruches 1.The invention relates to a pivotable ink knife carrier in rotary printing machines according to the preamble of claim 1.

Es ist bekannt, die Dosierung der Farbzufuhr in Offsetdruckmaschinen mittels Farbdosierelementen in einem Farbkasten vorzunehmen, der mit einer Farbkastenwalze zusammenwirkt. Auf der Farbkastenwalze wird dabei eine unterschiedlich profilierte Farbschicht erzeugt, die sich aus der Positionierung der Farbdosierelemente bzw. der Farbmesser gegenüber der Farbkastenwalze ergibt.It is known to meter the ink supply in offset printing machines by means of ink metering elements in an ink fountain, which interacts with an ink fountain roller. A differently profiled ink layer is produced on the ink fountain roller, which results from the positioning of the ink metering elements or the ink knife relative to the ink fountain roller.

Um eine möglichst gute Reproduzierbarkeit dieser Farbschichten zu erzielen, ist eine exakte Lagerung des Farbkastens gegenüber der Farbkastenwalze notwendig. Es besteht auch die Notwendigkeit, daß der Farbkasten zu Reinigungs- und Einstellzwecken so weit von der Farbkastenwalze abgestellt werden kann, daß eine gute Bedienung möglich ist.In order to achieve the best possible reproducibility of these ink layers, an exact storage of the ink fountain relative to the ink fountain roller is necessary. There is also a need for the ink fountain to be placed so far away from the ink fountain roller for cleaning and adjustment purposes that good operation is possible.

Ein gattungsgemäßer verschwenkbarer farbkastenloser Farbmesserträger in einer Rotationsdruckmaschine ist durch die GB-A-6 05 092 bekannt geworden. Der Farbmesserträger ist schwenkbar um eine horizontale Schwenkachse. Sie ist so zum Schwerpunkt des Farbmesserträgers beabstandet, daß er beim Anschwenken an eine Duktorwalze kopflastig wird. Der Farbmesserträger, die Duktorwalze und eine Filmwalze sind gemeinsam in zwei Lagerböcken gelagert. Der Farbmesserträger weist Farbmesser auf, deren Unterseite mit der Duktorwalze einen Dosierspalt bildet.A generic swiveling ink fountain carrier without ink fountain in a rotary printing press has become known from GB-A-6 05 092. The ink knife holder can be swiveled around a horizontal one Swivel axis. It is so spaced from the center of gravity of the ink knife carrier that it becomes top-heavy when swiveled against a duct roller. The ink knife carrier, the duct roller and a film roller are stored together in two bearing blocks. The ink knife carrier has ink knives, the underside of which forms a metering gap with the duct roller.

Der Erfindung liegt die Aufgabe zugrunde, einen durch Verschwenken leicht an einen Farbduktor anstellbaren Farbmesserträger zu schaffen, dessen Lage in seiner Arbeitsstellung exakt und selbsttätig reproduzierbar ist.The invention has for its object to provide an ink knife holder which can be easily adjusted by swiveling it to a color duct, the position of which in its working position can be reproduced exactly and automatically.

Erfindungsgemäß wird diese Aufgabe durch das Kennzeichen des Patentanspruches 1 gelöst.According to the invention, this object is achieved by the characterizing part of patent claim 1.

Bei der Anwendung der Erfindung treten insbesondere nachfolgende Vorteile auf. Nach erfolgter Reinigung des Farbmessers im abgeschwenkten Zustand ist der Farbmesserträger fernbedienbar und somit, von der Bedienperson nicht mehr beeinflußbar, exakt in die vorgesehene Arbeitslage an die Farbkastenwalze anstellbar. Dabei ist der Kraftaufwand für das Betätigen des Farbmesserträgers gering, da die durch die Achszapfen des Farbmesserträgers verlaufende axiale Mittellinie in der Nähe des Schwerpunktes des Farbmesserträgers verläuft. Durch eine selbsttätige und fernbedienbare Verriegelung des Farbmesserträgers in der angeschwenkten Arbeitsstellung wird ein Maschinenlauf nur nach erfolgter Verriegelung garantiert.When using the invention, the following advantages occur in particular. After cleaning the ink knife in the swiveled-out state, the ink knife carrier can be operated remotely and thus, can no longer be influenced by the operator, can be adjusted exactly to the intended working position on the ink fountain roller. The effort required to actuate the ink knife carrier is low since the axial center line running through the axle journals of the ink knife carrier runs in the vicinity of the center of gravity of the ink knife carrier. Automatic and remote-controlled locking of the ink knife holder in the swiveled-in working position guarantees that the machine will only run after it has been locked.

Infolge der Unterteilung des Farbmesserträgers in vier sich über die gesamte Maschinenbreite erstreckende Teile auf austauschbaren Halterungen kann im Bedarfsfall ein schneller Austausch der Halterungen erfolgen.As a result of the subdivision of the ink knife carrier into four parts that extend over the entire width of the machine on exchangeable holders, the holders can be exchanged quickly if necessary.

The cross member 12 is connected to the side walls of the machine frame, not shown.

Der Farbmesserträger 1 besitzt an seinen Stirnseiten Bohrungen 14; 16, in die Arretierbolzen 17; 18 mit ihrem jeweils ersten Ende 19; 21 eingreifen. Die Arretierbolzen 17; 18 sind an ihrem zweiten Ende 22; 23 jeweils mit einem Zahnrad 24; 26 fest verbunden. Die Arretierbolzen 17; 18 sind einerseits im Lagerbock 9; 11 und andererseits in Lagern 27; 28 befestigt. Die Arretierbolzen 17; 18 weisen in ihrem zwischen dem ersten Ende 19; 21 und dem zweiten Ende 22; 23 gelegenen mittleren Teil ein Außengewinde 29; 31 auf, das in einer Gewindebohrung 32; 33 des Lagerbockes 9; 11 bewegbar ist.The ink knife carrier 1 has holes 14 on its end faces; 16, in the locking bolt 17; 18 with their respective first ends 19; 21 intervene. The locking bolts 17; 18 are 22 at their second end; 23 each with a gear 24; 26 firmly connected. The locking bolt 17; 18 are on the one hand in the bearing block 9; 11 and on the other hand in bearings 27; 28 attached. The locking bolt 17; 18 have in their between the first end 19; 21 and the second end 22; 23 located middle part an external thread 29; 31 on that in a threaded bore 32; 33 of the bearing block 9; 11 is movable.

Das Zahnrad 24 des Arretierbolzens 17 kämmt mit einem Zahnrad 34, das direkt mit der Antriebswelle eines auf dem Lagerbock 9 befestigten Motors 36 verbunden ist. Das Zahnrad 26 des Arretierbolzens 18 kämmt mit einem Zahnrad 37, wobei das Zahnrad 37 mit seinem Innengewinde 35 mit einem Außengewinde 40 des Achszapfens 7 in Wirkverbindung steht. Das Zahnrad 37 weist einen festen Anschlag 38 auf und kämmt mit einem Zahnrad 39 eines Motors 41, der auf dem Lagerbock 11 befestigt ist. Das dem Gehäuse 2 abgewandte Ende des Achszapfens 7 nimmt eine Scheibe 42 mit einem fest darauf angeordneten Anschlag 43 auf. Die Scheibe 42 ist mit der dem Gehäuse 2 abgewandten Seite des Achszapfens 7 durch Schrauben 44 verbunden.The gear 24 of the locking bolt 17 meshes with a gear 34 which is directly connected to the drive shaft of a motor 36 fastened on the bearing block 9. The gearwheel 26 of the locking bolt 18 meshes with a gearwheel 37, the gearwheel 37 with its internal thread 35 being in operative connection with an external thread 40 of the axle journal 7. The gear 37 has a fixed stop 38 and meshes with a gear 39 of a motor 41 which is fastened on the bearing block 11. The end of the journal 7 facing away from the housing 2 receives a disk 42 with a stop 43 fixedly arranged thereon. The disk 42 is connected to the side of the axle 7 facing away from the housing 2 by screws 44.

Gemäß Fig. 4 und 7 ist der Farbmesserträger 1 im Schnitt dargestellt und zeigt einen Antrieb für das verstellbare Farbmesser 4, das mittels einer Leiste 46 und Schrauben 47 am Gehäuse 2 des Farbmesserträgers 1 einseitig eingespannt ist. Jede der Halterungen 3 nach Fig. 1 ist mit mehreren Stelleinheiten entsprechend dem Format der Maschine ausgestattet; hier stellvertretend mit Motor 48 gekennzeichnet. Der Motor 48 ist auf seiner Antriebswelle 49 mit einer Exzenterscheibe 51 versehen. Die Exzenterscheibe 51 wirkt über einen Hebel 52, der auf der Halterung 3 schwenkbar im Punkt 53 gelagert ist, auf das Farbmesser 4. Der Hebel 52 greift durch eine im Gehäuse 2 befindliche Bohrung 54. Die Halterungen 3 sind über Schrauben 56 lösbar mit dem Gehäuse 2 verbunden. Die exakte Lage der Halterungen 3 wird durch nicht dargestellte Anschläge im Farbmesserträger 1 gewährleistet.4 and 7, the ink knife carrier 1 is shown in section and shows a drive for the adjustable ink knife 4, which is clamped on one side by means of a bar 46 and screws 47 on the housing 2 of the ink knife carrier 1. Each of the brackets 3 according to FIG. 1 is equipped with several actuating units in accordance with the format of the machine; here marked with engine 48. The motor 48 is provided on its drive shaft 49 with an eccentric disk 51. The Eccentric disc 51 acts on the ink knife 4 via a lever 52, which is pivotably mounted on the holder 3 at point 53. The lever 52 engages through a bore 54 in the housing 2. The holders 3 can be detached from the housing 2 via screws 56 connected. The exact position of the brackets 3 is ensured by stops, not shown, in the ink knife carrier 1.

Die Farbmesser 4 wirken im Betriebszustand mit ihrer Unterseite jeweils mit einer der 1/4-breiten Farbkastenwalze oder Duktor 56 in der Weise zusammen, daß sie einen Farbdosierspalt bilden. Der Duktor 56 steht mit seinem Umfang mit einer Filmwalze 57 in Verbindung. Vor dem Duktor 56 ist eine Farbauftragleiste 58 angeordnet, die jeweils über eine Farbführung 59 mit einem nicht dargestellten Farbvorratsbehälter in Verbindung steht. Der Duktor 56 und die Filmwalze sind jeweils beidseitig in den Lagerböcken 9; 11 gelagert.In the operating state, the ink knives 4 interact with their underside in each case with one of the 1/4 wide ink fountain rollers or ductors 56 in such a way that they form an ink metering gap. The circumference of the ductor 56 is connected to a film roller 57. A paint applicator bar 58 is arranged in front of the ductor 56, each of which is connected to an ink reservoir (not shown) via a paint guide 59. The ductor 56 and the film roller are each on both sides in the bearing blocks 9; 11 stored.

Die Funktionsweise ist nachfolgend beschrieben: Der Farbmesserträger 1 befindet sich zunächst in der nach Fig. 1 bis 4 angegebenen Arbeits- oder Betriebsstellung, d. h. das Farbmesser 4 ist mit der von der Farbauftragleiste 58 aufgetragenen Farbe auf den Duktor 56 in Verbindung. Von einer zentralen Stelle, beispielsweise von einem nicht dargestellten Maschinenleitstand aus, wird das Signal zum Abschwenken des Farbmesserträgers 1 gegeben. Der Motor 36 erhält einen Impuls und wird in Drehbewegung versetzt, so daß die Zahnräder 34 und 24 miteinander kämmen und somit der Arretierbolzen 17 über sein Außengewinde 29 mit der Gewindebohrung 32 in Kontakt kommt und sich in Pfeilrichtung C nach außen bewegt.The mode of operation is described below: The ink knife carrier 1 is initially in the working or operating position shown in FIGS. 1 to 4, ie the ink knife 4 is connected to the ink applied by the ink application bar 58 to the ductor 56. The signal for pivoting the ink knife carrier 1 is given from a central point, for example from a machine control station (not shown). The motor 36 receives a pulse and is set in rotary motion so that the gears 34 and 24 mesh with one another and thus the locking bolt 17 comes into contact with the threaded bore 32 via its external thread 29 and moves outward in the direction of arrow C.

Sobald der Arretierbolzen 17 mit seinem ersten Ende 19 mit der Bohrung 14 an der Stirnseite des Gehäuses 2 außer Eingriff ist, wird ein Schalter 61 betätigt, der einen Impuls auslöst zur Betätigung des Motors 41 mit seinem fest verbundenen Zahnrad 39.As soon as the locking pin 17 with its first end 19 is disengaged from the bore 14 on the end face of the housing 2, a switch 61 is actuated, which triggers a pulse for actuating the motor 41 with its firmly connected gear 39.

Die Ausgangsstellung ist so, wie in Fig. 2 bis 4 dargestellt. Durch Drehen auf der Welle des Motors 41 befindlichen Zahnrades 39 in Pfeilrichtung D nach Fig. 3 wird das Zahnrad 37 mit seinem Anschlag 38 in entsprechende Umdrehung versetzt. Gemäß Fig. 2 hat das Zahnrad zunächst noch einen Abstand a von der Scheibe 42, so daß sich der Anschlag 38 am Anschlag 43 vorbeibewegt. Da die Nabe des Zahnrades 37 mit einem Innengewinde 35 verbunden ist, bewegt sich das Zahnrad 37 in Pfeilrichtung E nach Fig. 2, so daß sich der Abstand a verringert und der Anschlag 38 nach einer reichlichen Umdrehung des Zahnrades 37 hinter dem Anschlag 43 zu liegen kommt. Dies wird durch die schraffierte Darstellung des Anschlages 38 als Stellung 38' in Fig. 3 gezeigt.The starting position is as shown in FIGS. 2 to 4. By rotating gear 39 located on the shaft of the motor 41 in the direction of arrow D according to FIG. 3, the gear 37 with its stop 38 is set into a corresponding rotation. 2, the gear has a distance a from the disk 42 so that the stop 38 moves past the stop 43. Since the hub of the gearwheel 37 is connected to an internal thread 35, the gearwheel 37 moves in the direction of the arrow E according to FIG. 2, so that the distance a is reduced and the stop 38 lies behind the stop 43 after an extensive rotation of the gearwheel 37 is coming. This is shown by the hatched representation of the stop 38 as position 38 'in FIG. 3.

Diese reichliche Umdrehung, genauer gesagt 1,2 Umdrehungen des Zahnrades 37, haben ausgereicht, um den Arretierbolzen 18 über sein Außengewinde 31 in Verbindung mit der Gewindebohrung 33 außer Eingriff zu bringen mit der Bohrung 16 in der Stirnseite des Gehäuses 2. Das Zahnrad 26 führt in dieser Zeit ca. sechs Umdrehungen aus.This abundant revolution, more precisely 1.2 revolutions of the gearwheel 37, was sufficient to disengage the locking bolt 18 via its external thread 31 in connection with the threaded bore 33 with the bore 16 in the end face of the housing 2. The gearwheel 26 guides during this time about six revolutions.

Nun legen die nach 1,2 Umdrehungen des Anschlages 38 nebeneinanderliegenden Anschläge 38'; 43 nach Fig. 3 noch gemeinsam etwa 0,3 Umdrehungen in Pfeilrichtung D' zurück und nehmen dann die in Fig. 6 gezeigte Lage ein. Da der Anschlag 43 mitbewegt wurde, der mit dem Gehäuse 2 über die den Achszapfen 7 und die Scheibe 42 fest verbunden ist, kommt es zur Schwenkbewegung des Farbmesserträgers 1 um seine Schwenkachse 60. Der Farbmesserträger 1 nimmt nunmehr die abgeschwenkte Stellung nach Fig. 5 und 7 ein. Der Motor 41 schaltet ab, in dem der Farbmesserträger 1 gemaß Fig. 7 gegen einen Schalter 55 fährt. Die Unterseite des Farbmessers 4 ist in einer Abschwenkendstellung (Fig. 7) von der Duktorwalze 56 abgewandt.Now place the stops 38 'lying next to each other after 1.2 turns of the stop 38; 43 according to FIG. 3 together about 0.3 revolutions in the direction of arrow D 'and then assume the position shown in FIG. 6. Since the stop 43 has also been moved, which is firmly connected to the housing 2 via the axle journal 7 and the disk 42, the ink knife carrier 1 pivots about its pivot axis 60. The ink knife carrier 1 now takes the pivoted position according to FIGS 7 a. The motor 41 switches off by moving the ink knife carrier 1 against a switch 55 as shown in FIG. 7. The underside of the ink knife 4 faces away from the duct roller 56 in a swiveled-down end position (FIG. 7).

Der Abstand a zwischen dem Zahnrad 37 und der Scheibe 42 hat sich aus der Fig. 3 zum Abstand b nach Fig. 5 verringert. Nunmehr können die Farbmesser 4 leicht gereinigt werden, im Bedarfsfall auch die Farbauftragleiste 58.The distance a between the gearwheel 37 and the disk 42 has decreased from FIG. 3 to the distance b according to FIG. 5. The color knives 4 can now be easily cleaned and, if necessary, the color application bar 58.

Beim Anschwenken des Farbmesserträgers 1 von der Ruhestellung bzw. Reinigungsstellung in die Arbeitsstellung wird wie folgt verfahren: Gemäß Fig. 5 und 6 erhält der Motor 41 einen Impuls von zentraler Stelle aus und läuft an. Somit dreht sich das Zahnrad 39 in Pfeilrichtung F. Das mit dem Zahnrad 39 kämmende Zahnrad 37 mit dem Anschlag 38 dreht sich ebenfalls in Pfeilrichtung F'. Der Anschlag 43 mit der Scheibe 42 folgt dem Anschlag 38 fest anliegend in Pfeilrichtung F', da die Schwenkachse 60 so in der Nähe, d. h. im Abstand h, z. B. zehn Millimeter zum Schwerpunkt S, des Farbmesserträgers 1 angeordnet ist, daß sich der Teil des Farbmesserträgers 1, der die Halterungen 3 und die Antriebe trägt, geringfügig im Übergewicht, d. h. leicht kopflastig ist, so daß der Farbmesserträger gemäß Fig. 7 das Bestreben hat, in Pfeilrichtung G selbsttätig eine Schwenkbewegung auszuführen.When pivoting the ink knife carrier 1 from the rest position or cleaning position into the working position, the procedure is as follows: According to FIGS. 5 and 6, the motor 41 receives a pulse from a central point and starts up. The gear 39 thus rotates in the direction of the arrow F. The gear 37 meshing with the gear 39 with the stop 38 also rotates in the direction of the arrow F '. The stop 43 with the disk 42 follows the stop 38 tightly in the direction of the arrow F ', since the pivot axis 60 is so close, ie at a distance h, z. B. ten millimeters to the center of gravity S, the ink knife carrier 1 is arranged so that the part of the ink knife carrier 1, which carries the brackets 3 and the drives, is slightly overweight, ie slightly top-heavy, so that the ink knife carrier according to FIG. 7 the effort has to perform a pivoting movement automatically in the direction of arrow G.

Der Farbmesserträger 1 schwenkt somit aus seiner in Fig. 7 dargestellten Lage in Pfeilrichtung G in die in Fig. 4 gezeigte Lage. Das bedeutet, daß der Schwerpunkt S ebenfalls einen Weg vom I. zum IV. Quadranten zurücklegt, bezogen auf ein Koordinatensystem, dessen Ursprung auf der Rotationsachse 60 des Farbmesserträgers 1 liegt.The ink knife carrier 1 thus pivots from its position shown in FIG. 7 in the direction of arrow G into the position shown in FIG. 4. This means that the center of gravity S also travels a path from the I. to the IV. Quadrant, based on a coordinate system whose origin lies on the axis of rotation 60 of the ink knife carrier 1.

Nachdem beide Anschläge 38; 43 etwa 0,3 Umdrehungen gemeinsam zurückgelegt haben, ist der Farbmesserträger 1 wieder in die Arbeitsstellung gegen einen nicht dargestellten Anschlag zurückgeschwenkt. Die Anschläge 38; 43 nehmen nunmehr die Lage 43; 38' nach Fig 3 ein. Die Scheibe 42 mit dem Anschlag 43 bleibt stehen und das Zahnrad 37 mit dem Anschlag 38 dreht sich noch 1,2 Umdrehungen, wobei nach einer Umdrehung die Anschläge 38; 43 gemäß dem Abstand a nach Fig. 2 aneinander vorbeilaufen.After both stops 38; 43 have traveled approximately 0.3 revolutions together, the ink knife carrier 1 is pivoted back into the working position against a stop, not shown. The stops 38; 43 now take the position 43; 38 'according to FIG. 3. The disc 42 with the stop 43 stops and the gear 37 with the stop 38 rotates another 1.2 turns, the stops 38; 43 run past each other according to the distance a according to FIG. 2.

Somit hat auch der mit Gewinde versehene Arretierbolzen 18 infolge des Kämmens des Zahnrades 37 mit dem Zahnrad 26 eine Bewegung in Richtung Gehäuse 2 ausgeführt, und der Arretierbolzen 18 ist mit seinem ersten Ende 21 in die Verriegelungsstellung in der Bohrung 16 gefahren.Thus, the threaded locking bolt 18 has made a movement in the direction of the housing 2 due to the meshing of the gear 37 with the gear 26, and the locking bolt 18 has moved with its first end 21 into the locking position in the bore 16.

Durch einen in der Bohrung 16 angeordneten Schalter 62 wird der Motor 41 abgeschaltet und der Motor 36 eingeschaltet zwecks Verriegelung mittels Arretierbolzen 17 in der Bohrung 14.The motor 41 is switched off by a switch 62 arranged in the bore 16 and the motor 36 is switched on for the purpose of locking by means of locking bolts 17 in the bore 14.

Die auf den Halterungen 3 fixierten zonalen Stelleinheiten 48 können im demontierten Zustand voreingestellt werden; dadurch kann die Montage stark vereinfacht werden.The zonal control units 48 fixed on the brackets 3 can be preset in the disassembled state; this can greatly simplify assembly.
