Description

Die vorliegende Erfindung betrifft einen Stellmechanismus für die zonenweise Einstellung von in Druckmaschinen, insbesondere Offsetdruckmaschinen eingesetzten Rakel. Beim Einstellen eines Rakels der kleinen bis mittelgrossen Offsetdruckmaschinen müssen je nach Grösse 16 bis 50 Stellschrauben verstellt werden. Dieser Einstellvorgang geschieht erstmals beim Einrichten der neuen Offsetdruckmaschine und muss für jeden Druck und/oder jede neue Druckfarbe neu eingestellt werden. Dieser Vorgang wird dadurch kontrolliert, dass man auf Papier andruckt und mit dem Densitometer die Farbdicke misst. Darauf wird die Rakel nachgestellt und wieder gemessen, wie sich die Farbstärke gemäss Densitometer neu eingestellt hat und nochmals wird die Rakel nachgestellt etc.. Dieser Vorgang kann sich viele Male wiederholen und ist extrem zeitaufwendig.The present invention relates to an adjusting mechanism for the zone-wise adjustment of doctor blades used in printing machines, in particular offset printing machines. When setting a squeegee of the small to medium-sized offset printing machines, depending on the size, 16 to 50 set screws have to be adjusted. This setting process takes place for the first time when setting up the new offset printing press and must be set again for each print and / or each new printing ink. This process is controlled by printing on paper and measuring the color thickness with the densitometer. Then the squeegee is readjusted and measured again, how the color strength has been adjusted according to the densitometer and the squeegee is readjusted etc. This process can be repeated many times and is extremely time-consuming.

Die hochpräzise Einstellung verlangt eine feindosierbare Zustellung der Stellschrauben. Eine entsprechende Lösung ist beispielsweise aus der DE-A-2′435′321 bekannt.The high-precision setting requires a finely adjustable delivery of the set screws. A corresponding solution is known for example from DE-A-2'435'321.

Aus der nächstliegenden US-2′607′315 ist die Verwendung eines einteiligen, nicht unterteilten Rakels bekannt, wobei in mehreren nebeneinander liegenden Zonen je eine einfache, lose andrückende Stellschraube auf das Rakel wirkt, bei dem an jeder Stellschraube eine die Position der Stellschraube anzeigende Zähluhr angeordnet ist. Bei dieser Konstruktion bewirkt die Einstellung einer Stellschraube nicht nur die Verstellung des direkt beeinflussten Bereiches, sondern auch die benachbarten Zonen werden beeinflusst.From the closest US-2'607'315 the use of a one-piece, not subdivided squeegee is known, with a simple, loosely pressing adjusting screw acting on the squeegee in several adjacent zones, in which a position indicating the adjusting screw is displayed on each adjusting screw Counter is arranged. With this construction, the adjustment of an adjusting screw not only effects the adjustment of the directly influenced area, but also the neighboring zones.

Diese Korrektur der benachbarten Zonen verlangt aber nicht allein die Anlegung von Druck-, sondern auch oftmals von Zugkräften entsprechend schlägt die DE-A-24′35′321 die starre Verbindung von Stellschrauben mit dem Rakel vor. Die Beeinflussung der nebeneinander liegenden Zonen wird hierdurch jedoch nicht eliminiert und die Einstellung verlangt folglich immer Folgekorrekturen.This correction of the adjacent zones does not only require the application of pressure, but also often of tensile forces accordingly, DE-A-24'35'321 proposes the rigid connection of set screws with the squeegee. This does not, however, eliminate the influence of the zones lying next to each other and the setting therefore always requires subsequent corrections.

Einen völlig anderen Weg zeigen die US-A-3′559′573 und die US-A-4′372′207 auf. Hier wird mit einer speziellen Quertraverse gearbeitet, in der eine Vielzahl nebeneinander liegenden Schieber die individuelle Farbzufuhr in jeder Zone erlaubt. Das eigentliche Rakel liegt nicht mehr an der Duktorwalze an, sondern dient nur noch der Dichtung des Farbkastens. Dies führt zwar zu einer exakten Einstellbarkeit, aber zum Preis einer erheblich aufwendigeren Lösung.The US-A-3'559'573 and US-A-4'372'207 show a completely different way. Here, a special cross-beam is used, in which a large number of slides next to each other allow individual ink supply in each zone. The actual doctor blade is no longer on the duct roller, but only serves to seal the ink fountain. This leads to an exact adjustability, but at the price of a considerably more complex solution.

Die vorliegende Erfindung stellt sich nun zur Aufgabe, einen Stellmechanismus zu schaffen, mit dessen Hilfe beim wiederholten Einstellvorgang, Zeit und Papier gespart werden kann, der sich an einer maschineneigenen Quertraverse anbauen lässt und die Vorteile der bekannten Systeme der Stellmechanismen vereinigt.The present invention has for its object to provide an adjusting mechanism, with the help of the repeated adjustment process, time and paper can be saved, which can be attached to a machine's own cross-beam and combines the advantages of the known systems of adjusting mechanisms.

Diese Aufgabe wird gelöst mittels eines Stellmechanismus gemäss Anspruch 1.This object is achieved by means of an actuating mechanism according to claim 1.

Die bevorzugte Verwendung des erfindungsgemässen Stellmechanismuses geht aus den Ansprüchen 6 und 7 hervor.The preferred use of the adjusting mechanism according to the invention is evident from claims 6 and 7.

In der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes dargestellt und in der nachfolgenden Beschreibung erläutert.In the drawing, an embodiment of the subject matter of the invention is shown and explained in the following description.

Es zeigt:

Figur 1
einen Schnitt durch den Stellmechanismus quer zur Rakellängsrichtung und ausserhalb des Bereiches eines Einschnittes des Rakels, sowie
Figur 2
eine perspektivische Teilansicht, der der Duktorwalze abgewendeten Seite.
It shows:
Figure 1
a section through the adjusting mechanism transverse to the longitudinal direction of the squeegee and outside the area of an incision of the squeegee, and
Figure 2
a partial perspective view of the side facing away from the roller.

In der Figur 1 erkennt man das Rakel, welches durch Einschnitte senkrecht zu seiner Längsrichtung in Zonenbildende Zungen unterteilt ist. Die Zonenunterteilung des Rakels 1 erleichtert die Einstellung der Farbzufuhr, weil die Einstellung in einem Bereich des Rakels nicht zu Kräften führt, die eine Verformung des Rakels in Nachbarbereichen bewirkt. Das Rakel 1 bildet zusammen mit der Duktorwalze 2 und der Quertraverse 3 auf dem das Rakel montiert ist, Teil des Farbkastens der Druckmaschine, in dem die Druckfarbe 4 sich befindet.In FIG. 1 the doctor blade can be seen, which is divided into zone-forming tongues by incisions perpendicular to its longitudinal direction. The zone subdivision of the squeegee 1 facilitates the adjustment of the ink supply, because the adjustment in one area of the squeegee does not lead to forces which cause the squeegee to deform in adjacent areas. The doctor blade 1, together with the duct roller 2 and the crossbar 3 on which the doctor blade is mounted, forms part of the ink fountain of the printing press, in which the printing ink 4 is located.

In der bereits maschinenseitig vorhandenen Quertraverse 3 der Druckmaschine sind Durchgangsbohrungen 5 angebracht, die auf die einzelnen Zonen des Rakels 1 ausgerichtet sind. Jede Bohrung 5 hat einen erweiterten Bereich 51, der in einen leicht verjüngten Bereich mit Innengewinde 52 übergeht. In jeder Bohrung findet eine Stellschraube 6 Aufnahme. Die Stellschraube 6 ist zweiteilig. Sie besteht aus einer Zonenschraube 61 und einem Druckbolzen 62. Die Zonenschraube 61 hat einen langen dünnen Schaft 63, der in Richtung zum Rakel in einen verdickten Bereich 64 übergeht, in der eine Sacklochbohrung mit einem Gewinde angebracht ist. Im Sackloch mit Innengewinde 65 ist der Druckbolzen 62 eingeschraubt, der ein Aussengewinde 66 an seinem dem Rakel 1 abgewendeten Ende aufweist. An dem, dem Rakel 1, zugerichteten Ende hat der Druckbolzen 62 ein formschlüssig am Rakel 1 anliegender Kopf 67 der verschiebbar, aber unverdrehbar bezüglich dem Rakel 1 an diesem gleitend anliegt.
Die Zonenschraube 61 weist an seinem verdickten Bereich 64 ein Aussengewinde 68 auf, welches mit dem Innengewinde 52 des Durchgangloches 5 in der Quertraverse 3 kämmt. Die Steigungen des Aussengewindes 68 der Zonenschraube 61 und das Aussengewinde 66 des Druckbolzens 62 sind unterschiedlich. Hieraus folgt automatisch, dass pro Umdrehung am langen Schaft 63 der Zonenschraube 61, der Druckbolzen 62 sich lediglich um die Differenz der Steigungen der beiden sogenannten Gewinden relativ zum Rakel 1 verschieben wird. Hierdurch lässt sich eine äusserst genaue Einstellung von beispielsweise einen zehntel Millimeter pro Umdrehung oder weniger realisieren.Through holes 5 are provided in the cross-beam 3 of the printing press, which is already provided on the machine side, and are aligned with the individual zones of the doctor blade 1. Each bore 5 has an enlarged area 51 which merges into a slightly tapered area with an internal thread 52. A set screw 6 is accommodated in each hole. The set screw 6 is in two parts. she consists from a zone screw 61 and a pressure bolt 62. The zone screw 61 has a long, thin shaft 63 which merges in the direction of the doctor blade into a thickened region 64 in which a blind hole with a thread is made. The pressure bolt 62, which has an external thread 66 at its end facing away from the doctor blade 1, is screwed into the blind hole with an internal thread 65. At the end facing the squeegee 1, the pressure pin 62 has a form-fitting head 67 which rests positively on the squeegee 1 and which slidably but non-rotatably rests with respect to the squeegee 1.
The zone screw 61 has on its thickened area 64 an external thread 68 which meshes with the internal thread 52 of the through hole 5 in the cross-beam 3. The pitches of the external thread 68 of the zone screw 61 and the external thread 66 of the pressure bolt 62 are different. From this it follows automatically that per revolution on the long shaft 63 of the zone screw 61, the pressure pin 62 will only move by the difference in the pitches of the two so-called threads relative to the squeegee 1. This enables an extremely precise setting of, for example, a tenth of a millimeter per revolution or less to be achieved.

Auf das Ende des dünnen Schaftes 63 ist eine Zähluhr 8 aufgesteckt. Solche Zähluhren sind auf dem Markt als Potentiometeranzeiger erhältlich. Die Zähluhr hat ein Gehäuse 81, in dem ein Getriebe und ein Mitnehmerzähler untergebracht ist. Der Stand des Mitnehmerzählers ist an der Anzeige 82 direkt ablesbar. Durch jede vollständige Drehung am Drehknopf 83 wird der Mitnehmerzähler um eine Position weiter verdreht. Selbstverständlich wäre in der Zähluhr 8 auch nochmals ein Untersetzungsgetriebe unterbringbar, doch dürfte dies nicht erforderlich sein.A counter clock 8 is plugged onto the end of the thin shaft 63. Such counters are available on the market as potentiometer indicators. The counter clock has a housing 81 in which a gear and a driver counter is accommodated. The status of the driver counter can be read directly on the display 82. Each complete turn of the knob 83 rotates the driver counter one position. Of course, a reducer could also be accommodated in the counter 8, but this should not be necessary.

Jede Zähluhr könnte für sich durch entsprechende Fixierung mit der Quertraverse 3 der Druckmaschine verbunden sein. Dies wäre jedoch aufwendig und würde die spätere Umrüstung einer Druckmaschine mit dem erfindungsgemässen Stellmechnismus verteuern und komplizieren. Da ohnehin jede Stellschraube bereits mit der Quertraverse 3 verbunden ist und die Zähluhren auf diese Stellschrauben aufgesetzt sind, genügt es die Zähluhren gegenübereinander gegen Verdrehen zu sichern. Dies geschieht erfindungsgemäss in der einfachsten Form dadurch, dass man die Zähluhrgehäuse 81 je mit einem in vertikaler Richtung als Passsitz ausgebildeten horizontalen Schlitz oder einer Durchgangsbohrung 84 quer durch das Gehäuse 81 verschiebt. Schiebt man nun parallel zur Quertraverse durch sämtliche Schlitze oder Bohrungen 84 in den Zähluhren 8 einen Stab, vorzugsweise einen Stahlstab 85, so sind alle Zähluhren 8 relativ zueinander verdrehgesichert. Damit dies möglichst spielfrei erfolgt, sollte der Stahlstab 85 mit Passsitz in den Bohrungen 84 in den Gehäusen 81 eingepasst sein.
In vielen Fällen wird es bei der Verwendung bereits erhältlichen Zähluhren 8 nicht möglich sein, diese mit Durchgangsbohrungen zu versehen. Es wird daher vorgeschlagen, auf der Rückseite des Gehäuses 81 ein quaderförmiges Klötzchen als Halteelement 86 anzubringen, beispielsweise durch Kleben, welches bereits mit einer Durchgangsbohrung 84 versehen ist.Each counter clock could be connected to the crossbar 3 of the printing press by appropriate fixation. However, this would be complex and would make the subsequent retrofitting of a printing press with the actuating mechanism according to the invention more expensive and complicated. Since each set screw is already connected to the crossbar 3 and the counters are placed on these set screws, it is sufficient to secure the counters against each other against rotation. According to the invention, this is done in the simplest form by displacing the counter housing 81 across the housing 81 with a horizontal slot designed as a vertical fit or a through hole 84. Now slide parallel to the crossbar through all slots or Bores 84 in the counter clocks 8 a rod, preferably a steel rod 85, so all counter clocks 8 are secured against rotation relative to one another. To ensure that this takes place as free of play as possible, the steel rod 85 should be fitted with a snug fit in the bores 84 in the housings 81.
In many cases it will not be possible to use through-bores when using already available counters 8. It is therefore proposed to attach a cuboid block as a holding element 86 to the rear of the housing 81, for example by gluing, which is already provided with a through hole 84.

Bei der Verwendung der erfindungsgemässen Stellmechanismus arbeitet man so, dass man beim erstmaligen Einsatz in jeder Zone für sich die Stellschraube 6 solange zuschraubt bis kein Farbübertrag mehr stattfindet. Nun stellt man sich die Zähluhr auf Null. Danach sind alle Uhren justiert und es lassen sich die gewünschten Werte pro Zone einstellen. Diese Werte, die je nach Druckvorlage unterschiedlich sind, lassen sich protokollieren und mit der Druckvorlage archivieren. Bei einer nächsten Auflage derselben Druckvorlage lassen sich nun sofort die mindestens annähernd korrekten Werte einstellen, die lediglich entsprechend der eingetretenen Abnützung des Rakels noch nachgestellt werden müssen. Dies ist jedoch mit geringem Aufwand möglich. Versuche haben gezeigt, dass auf diese Art die Einstellung des Rakels in einem Bruchteil der bisher erforderlichen Zeit unter entsprechender Papiereinsparung erfolgen kann.When using the adjusting mechanism according to the invention, one works in such a way that, when it is used for the first time in each zone, the adjusting screw 6 is screwed in until there is no more color transfer. Now you set the counter to zero. Then all clocks are adjusted and the desired values per zone can be set. These values, which differ depending on the print template, can be logged and archived with the print template. With a next edition of the same print template, the at least approximately correct values can now be set, which are only appropriate the wear of the squeegee must still be adjusted. However, this is possible with little effort. Tests have shown that in this way the doctor blade can be adjusted in a fraction of the time previously required, with the corresponding savings in paper.
