Description

Die Erfindung betrifft eine Farbdosiervorrichtung für eine Druckmaschine, bestehend aus mittels Farbfilmdickeneinsiellelementen entgegen der Federvorspannung einer Feder-Bolzen-Systemes anstellbaren, die Farbfilmdicke dosierenden Elementen, die individuell über die Länge der Farbkastenwalze durch Verschwenken um eine gemeinsame Achse einstellbar sind.The invention relates to an ink metering device for a printing press, consisting of elements that can be adjusted by means of ink film thickness elements against the spring preload of a spring-bolt system, the ink film thickness metering elements that can be individually adjusted over the length of the ink fountain roller by pivoting about a common axis.

Eine Farbdosiervorrichtung dieser Art ist aus der CH-PS 442 365 bekannt, wobei nur ein einziges sich über die gesamte Walzenlänge erstreckendes Farbmesser verwendet wird. Eine ähnliche Farbdosiervorrichtung ist aus der DE-PS 639 293 bekannt, bei der anstelle eines durchgehenden Messers mehrere nebeneinanderangeordnete Farbabstreif- bzw. Dosierelemente verwendet werden.A color metering device of this type is known from CH-PS 442 365, only a single color meter extending over the entire roller length being used. A similar color metering device is known from DE-PS 639 293, in which several color stripping or metering elements arranged side by side are used instead of a continuous knife.

Bei den bekannten Vorrichtungen sind keine Mittel zur Begrenzung eines Messer - Minimalabstandes von der Walzenoberfläche vorhanden. Das Messer kann hier mittels der betreffenden Einstellvorrichtung ohne weiteres bis zur Walzenoberfläche hingedrückt werden, was zu Beschädigung und vorzeitiger Abnützung führt. Ausserdem ist die Möglichkeit eines Kantenwechsels an dem gleichen Messerelement nicht vorhanden, so dass nach Abnützung einer Anstellkante das gesamte Messer bzw. Messerelement ausgewechselt werden muss.In the known devices there are no means for limiting a minimum knife distance from the roll surface. The knife can be easily pushed up to the roller surface by means of the relevant setting device, which leads to damage and premature wear. In addition, there is no possibility of an edge change on the same knife element, so that the entire knife or knife element has to be replaced after a contact edge has worn out.

Aufgabe der Erfindung ist es, eine Farbdosiervorrichtung der gattungsgemässen Art zu schaffen, die sowohl bei Abnutzung einer Masserkante ein leichtes und sofortiges Auswechseln derselben ermöglicht und zusätzlich verhindert, dass der Abstand dieser Kante von der Farbkastenwalzenoberfläche durch fehlerhafte Einstellung einen Minimalabstand (Sm;n) unterschreitet und auf der Walze schleift.The object of the invention is to provide an ink metering device of the generic type which, both when a mass edge is worn, enables it to be replaced easily and immediately, and additionally prevents the distance of this edge from the ink fountain roller surface from being incorrectly set to a minimum distance (S m ; n). falls below and grinds on the roller.

Diese Aufgabe wird gemäss dem Kennzeichen des Patentanspruchs 1 gelöst. Weitere vorteilhafte Ausgestaltungen der erfindungsgemässen Farbdosiervorrichtung ergeben sich aus den Unteransprüchen in Verbindung mit der Beschreibung und den Zeichnungen.This object is achieved according to the characterizing part of patent claim 1. Further advantageous embodiments of the color metering device according to the invention result from the subclaims in conjunction with the description and the drawings.

Durch die Verwendung von zonenbreiten Scheiben auf einer Achse, vorzugsweise mit vier Kanten, ist durch die gemeinsame Bearbeitung der Scheiben eine optimale Genauigkeit bei der Fertigung erzielbar, so dass die seitliche Abdichtung zwischen den Scheiben verbessert und die Justierbarkeit und Einstellgenauigkeit erhöht wird. Eine weitere wesentliche Verbesserung im Vergleich zu den bekannten Systemen wird durch die erfindungsgemässe Verwendung der Feder-Bolzen-Kombination erreicht, da dadurch die Einstellung einer Null-Stellung, d. h. die Definition des geringsten Spaltes, möglich ist.By using zone-wide disks on one axis, preferably with four edges, the joint machining of the disks achieves optimum manufacturing precision, so that the lateral sealing between the disks is improved and the adjustability and setting accuracy is increased. A further significant improvement compared to the known systems is achieved by the use of the spring-bolt combination according to the invention, since this means that a zero position, ie. H. the definition of the smallest gap is possible.

Im folgenden wird die Erfindung anhand eines Ausführungsbeispiels im einzelnen beschrieben, wobei Bezug auf die beiliegenden Zeichnungen genommen wird. In diesen zeigen:

  • Fig. 1 eine schematisierte Farbdosiervorrichtung gemäss der Erfindung;
  • Fig. 2 eine Draufsicht auf die Vorrichtung gem. Fig. 1 und
  • Fig. 3 eine vergrösserte Darstellung eines erfindungsgemässen Dosierelmentes und der zugehörigen Einstellvorrichtung.
The invention is described in detail below using an exemplary embodiment, reference being made to the accompanying drawings. In these show:
  • 1 shows a schematic color metering device according to the invention;
  • Fig. 2 is a plan view of the device according. Fig. 1 and
  • Fig. 3 is an enlarged view of a metering element according to the invention and the associated setting device.

Fig. 1 zeigt eine Farbdosiervorrichtung gemäss der Erfindung, bei der an eine Farbduktorwalze 1 um eine Achse 5 verschwenkbare, die Farbfilmdicke auf der Farbduktorwalze 1 dosierende Elemente in Form von Scheiben 4 anstellbar sind. Wie aus Fig. 2 ersichtlich, sind die zonenbreiten Scheiben 4 auf der Achse 5 über die gesamte Länge der Farbduktorwalze 1 vorgesehen, so dass eine individuelle Führung der Farbfilmdicke an den verschiedenen Walzenbereichen möglich ist. Die einzelnen Scheiben 4 sind entsprechend den jeweiligen Anforderungen gruppenweise zusammengefasst, wobei die einzelnen Gruppen durch Abstandstücke 18 voneinander getrennt sind. Die Achse 5 ist dabei in einer Art Traverse (nicht im einzelnen gezeigt) gelagert. Die Lagerung ist so ausgebildet, dass ein Ausheben der Achse samt den Zonenscheiben zu Reinigungszwecken leicht möglich ist.1 shows an ink metering device according to the invention, in which elements in the form of disks 4 which can be pivoted about an axis 5 and which meter the ink film thickness on the ink roller 1 can be adjusted on an ink fountain roller 1. As can be seen from FIG. 2, the zone-wide disks 4 are provided on the axis 5 over the entire length of the inking roller 1, so that an individual guidance of the ink film thickness on the various roller areas is possible. The individual disks 4 are grouped together in accordance with the respective requirements, the individual groups being separated from one another by spacers 18. The axis 5 is mounted in a kind of crossbeam (not shown in detail). The bearing is designed in such a way that it is easy to lift the axis together with the zone disks for cleaning purposes.

Die Scheiben 4 weisen vorzugsweise einen quadratischen Querschnitt auf. Sie sind über Bohrungen auf die Achse 5 auffädelbar. Mittels Feder-Bolzen-Systemen werden die Scheiben 4 auf der Achse 5 in Uhrzeigerrichtung vorgespannt, d. h. durch die zwischen einer Traverse 2 und einer jeden Scheibe 4 befindliche in Fig. 1 durch die Bezugszahl 6 angedeutete Feder wird ein Drehmoment auf die Scheibe 4 in Uhrzeigerrichtung ausgeübt. Der Bestrebung der Scheibe 4, diesem Drehmoment nachzugeben und sich zu drehen, wird durch eine Stellschraube 3 entgegengewirkt. Die Stellschraube 3 ist in die Traverse 2 so eindrehbar, dass ihr linkes Ende gegen die Scheibe 4 stösst.The disks 4 preferably have a square cross section. They can be threaded onto the axis 5 via holes. By means of spring-bolt systems, the disks 4 are prestressed in a clockwise direction on the axis 5, i. H. Due to the spring indicated in FIG. 1 by the reference number 6 between a cross member 2 and each disk 4, a torque is exerted on the disk 4 in the clockwise direction. The endeavor of the disk 4 to give in to this torque and to rotate is counteracted by an adjusting screw 3. The set screw 3 can be screwed into the cross member 2 so that its left end abuts the washer 4.

Somit kann jede Scheibe 4 auf der Achse 5 durch Drehen der zugeordneten Stellschraube entgegen der Wirkung der Feder 6 verschwenkt werden, so dass der Abstand der der Farbduktorwalze 1 zugeneigten Kante zu der Farbduktorwalze 1 einstellt werden kann.Thus, each disc 4 can be pivoted on the axis 5 by turning the associated set screw against the action of the spring 6, so that the distance between the edge inclined to the inking roller 1 and the inking roller 1 can be adjusted.

Falls die jeweils angestellte Kante abgenützt ist, kann durch Herausnehmen der Achse 5 aus ihrer Lagerung und Drehung der Scheibe 4 eine weitere Kante für die Farbdosierung herangezogen werden. Durch die erfindungsgemässe Verwendung der mehrere Kanten aufweisenden Scheibe 4 ergibt sich somit der Vorteil, dass die einzelnen Scheiben 4 so lange verwendet werden können, bis alle zur Verfügung stehenden Kanten abgenützt, d. h. unbrauchbar, sind.If the edge in each case is worn out, a further edge can be used for the color metering by removing the axis 5 from its mounting and rotating the disc 4. The use according to the invention of the disk 4 having a plurality of edges thus results in the advantage that the individual disks 4 can be used until all available edges are worn, ie. H. are useless.

In Fig. 3 ist die vorteilhafte Ausgestaltung einer Scheibe mit der dieser zugeordneten Einstellmechanik im Detail gezeigt. Die in Fig. 3 gezeigte Scheibe 4 weist jeweils in der Nähe einer Kante eine Ausnehmung auf, in der eine Gewindebohrung vorgesehen ist. In Fig. 3 sind insgesamt entsprechend den vier Kanten der Einstellscheibe 4 die Ausnehmungen 9, 11, 13 und 15 und Gewindebohrungen 10, 12, 14 und 16 gezeigt.In Fig. 3 the advantageous embodiment of a disc with the associated adjustment mechanism is shown in detail. The disk 4 shown in Fig. 3 has a recess in the vicinity of an edge, in which a Ge wind hole is provided. In Fig. 3, the recesses 9, 11, 13 and 15 and threaded holes 10, 12, 14 and 16 are shown overall corresponding to the four edges of the shim 4.

Bei der aus Fig. 3 ersichtlichen Verwendung der linken unteren Kante der Scheibe 4 ist ein Gewindebolzen 7 durch den mittleren Steg eines H-förmigen Teils 8 geführt, der mit seinem unteren Ende in die Gewindebohrung 10 der Ausnehmung 9 eingeschraubt ist. Auf dem Gewindebolzen 7 ist eine Druckfeder 6 angeordnet, die mit ihrem linken Teil am Boden der Ausnehmung 9 und mit ihrem rechten Teil an dem mittleren Steg des H-förmigen Teils 8 anliegt. Dadurch wird das H-förmige Teil 8 mit seinem oberen, d. h. mit seinem rechten Ende gegen die Traverse 2 gedrückt. In dieser Weise wird durch die Federkraft ein Drehmoment für die Scheibe 4 erzeugt, durch das die Scheibe 4 bestrebt ist, sich um die Achse 5 in Uhrzeigerrichtung zu bewegen. Diese Drehung wird jedoch durch die Stellschraube 3 begrenzt.In the use of the lower left edge of the disk 4 shown in FIG. 3, a threaded bolt 7 is guided through the central web of an H-shaped part 8, the lower end of which is screwed into the threaded bore 10 of the recess 9. On the threaded bolt 7, a compression spring 6 is arranged, which rests with its left part on the bottom of the recess 9 and with its right part on the central web of the H-shaped part 8. As a result, the H-shaped part 8 with its upper, i.e. H. with its right end pressed against the traverse 2. In this way, the spring force generates a torque for the disk 4, by means of which the disk 4 tends to move in a clockwise direction about the axis 5. However, this rotation is limited by the set screw 3.

Wie bereits gesagt, kann durch Drehen der Stellschraube 3 entgegen der Kraft der Feder 6 somit die Scheibe 4 auf der Achse 5 verdreht werden, wodurch eine Einstellung des Abstandes, d. h. des Spaltes zwischen der Farbduktorwalze 1 und der in Aktion befindlichen Kante der Scheibe 4, vorgenommen werden kann.As already said, the disk 4 can thus be rotated on the axis 5 by turning the adjusting screw 3 against the force of the spring 6, whereby an adjustment of the distance, i. H. of the gap between the inking roller 1 and the edge of the disk 4 in action can be made.

Ein wesentliches Merkmal der Erfindung liegt darin, dass die kleinstmögliche Spalteinstellung durch die Verwendung der Feder-Bolzen-Kombination und des H-förmigen Teils 8 begrenzt wird. Wie in Fig. 3 gezeigt, wird das H-förmige Teil 8 mit seinem rechten Ende stets durch die Federkraft der Feder 6 gegen die Traverse 2 gedrückt. Das Mass der möglichen Drehung um die Achse 5, d. h. in Gegenuhrzeigerrichtung, wird durch eine entsprechend tiefe Eindrehung des Gewindebolzens 7 in die Gewindebohrung 10 festgelegt.An essential feature of the invention is that the smallest possible gap setting is limited by the use of the spring-bolt combination and the H-shaped part 8. As shown in Fig. 3, the H-shaped part 8 is always pressed with its right end by the spring force of the spring 6 against the cross member 2. The measure of possible rotation about axis 5, i.e. H. in the counterclockwise direction, is determined by a correspondingly deep screwing of the threaded bolt 7 into the threaded bore 10.

Wie aus Fig. 3 hervorgeht, wird die Verschwenkung der Scheibe 4 in Gegenuhrzeigerrichtung durch Drehen der Stellschraube 3 jeweils dann begrenzt, wenn der Kopf des Gewindebolzens 7 in Anlage mit der Traverse 2 kommt. In der Darstellung gemäss Fig. 3 findet sich der Gewindebolzen 7 mit seinem Kopf in Anlage mit der Traverse 2 und ausserdem wurde der Gewindebolzen 7 soweit als möglich in die Gewindebohrung 10 eingedreht. In dieser Stellung kommt der Absatz 17 in Anlage mit der Bodenfläche der Ausnehmung 9. Wird der Gewindebolzen 7 aus der Gewindebohrung 10 weiter herausgedreht, so begrenzt der Kopf des Gewindebolzens 7 die mögliche Verschwenkung der Scheibe 4 um die Achse 5 in Gegenuhrzeigerrichtung bereits früher.As can be seen from FIG. 3, the pivoting of the disc 4 in the counterclockwise direction is limited by turning the adjusting screw 3 when the head of the threaded bolt 7 comes into contact with the cross member 2. In the illustration according to FIG. 3, the threaded bolt 7 is found with its head in contact with the crossmember 2 and, furthermore, the threaded bolt 7 was screwed into the threaded bore 10 as far as possible. In this position, the shoulder 17 comes into contact with the bottom surface of the recess 9. If the threaded bolt 7 is further screwed out of the threaded bore 10, the head of the threaded bolt 7 limits the possible pivoting of the disk 4 about the axis 5 in the counterclockwise direction earlier.

Somit ermöglicht die erfindungsgemässe Ausbildung der Einstellvorrichtung der Scheibe 4 eine Verschwenkung der Scheibe 4 um die Achse 5 entsprechend der Einstellung der Stellschraube 3, wobei durch die wirksame Länge des aus der Gewindebohrung 10 herausragenden Gewindebolzens 7 die Verschwenkung in Gegenuhrzeigerrichtung begrenzt ist. Diese Begrenzung dient in vorteilhafter Weise als Null-Stellung, d. h. als die Stellung mit dem geringsten Spalt (Smin).Thus, the inventive design of the adjusting device of the disk 4 enables the disk 4 to be pivoted about the axis 5 in accordance with the setting of the adjusting screw 3, the pivoting in the counterclockwise direction being limited by the effective length of the threaded bolt 7 projecting from the threaded bore 10. This limitation advantageously serves as a zero position, i. H. than the position with the smallest gap (Smin).

Falls die an die Farbduktorwalze 1 angestellte Kante einer Scheibe 4 unbrauchbar ist, kann durch Herausnahme der Achse 5 aus der Lagerung durch eine entsprechende Drehung der Scheibe bzw. Scheiben eine andere Kante als Dosierkante verwendet werden. Wird beispielsweise die linke obere Kante als Farbdosierkante verwendet, so wird der Gewindebolzen 7 sowie die Feder 6 und das H-förmige Teil 8 in die Ausnehmung 15 bzw. in die Gewindebohrung 16 eingesetzt.If the edge of a disk 4 placed against the inking roller 1 is unusable, another edge can be used as the metering edge by removing the axis 5 from the storage by correspondingly rotating the disk or disks. If, for example, the upper left edge is used as the ink metering edge, the threaded bolt 7 as well as the spring 6 and the H-shaped part 8 are inserted into the recess 15 or into the threaded bore 16.
