Description

Die vorliegende Erfindung betrifft einen Stellmechanismus für in einzelne Zonen unterteilte Rakel von Druckma­schinen, insbesondere Offsetdruckmaschinen.
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 actuating mechanism for doctor blade doctor blades divided into individual zones, 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 adjusting screws have to be adjusted. This adjustment process takes place for the first time when setting up the new offset printing press and must be reset 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. Dies verbessert zwar die Exaktheit der Einstellung, verkürzt aber den eigentlichen Einstellvorgang nicht. Bei der Fein­einstellung wird nicht unerheblich viel Papier-Ausschuss produziert, was nicht nur unwirtschaftlich sondern auch umweltpolitisch bedenklich ist.The high-precision setting requires a fine adjustment of the set screws. A corresponding solution is known for example from DE-A-2'435'321. Although this improves the accuracy of the setting, it does not shorten the actual setting process. The fine adjustment produces a not inconsiderable amount of paper waste, which is not only uneconomical but also environmentally harmful.

Die vorliegende Erfindung stellt sich nun zur Aufgabe, einen Stellmechanismus zu schaffen, mit dessen Hilfe beim wiederholten Einstellvorgang, Zeit und Papier gespart wer­den soll.The present invention has for its object to provide an adjusting mechanism, with the help of the repeated adjustment, time and paper to be saved.

Diese Aufgabe wird gelöst mittels eines Stellmechanismus gemäss den kennzeichnenden Merkmalen des Ansprüches 1.This object is achieved by means of an adjusting mechanism in accordance with the characterizing features of claim 1.

Weitere Ausführungsvarianten ergeben sich aus den ab­hängigen Ansprüchen.Further design variants result from the dependent claims.

In der Zeichnung ist ein Ausführungsbeispiel des Er­findungsgegenstandes dargestellt und in der nachfolgenden Beschreibung erläutert. Es zeigt:

  • Figur 1 einen Schnitt durch den Stellmechanismus quer zur Rakellängsrichtung und
  • Figur 2 eine perspektivische Teilansicht.
In the drawing, an embodiment of the subject matter of the invention is shown and explained in the following description. It shows:
  • 1 shows a section through the adjusting mechanism transversely to the longitudinal direction of the squeegee and
  • Figure 2 is a partial perspective view.

In der Figur 1 erkennt man das Rakel, welches durch Ein­schnitte senkrecht zu seiner Längsrichtung in Zonen 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.1 shows the doctor blade, which is divided into zones 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 is screwed into the blind hole with an internal thread 65 and has an external thread 66 at its end facing away from the squeegee 1. At the end facing the squeegee 1, the pressure pin 62 has a form-fitting head 67, which rests on the squeegee 1 in a displaceable but non-rotatable manner 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 allows 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.
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.A counter clock 8 is attached to 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 rotary 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.
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 crossbeam 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 in that the counter housing 81 is moved across the housing 81 with a horizontal slot or a through hole 84 designed as a vertical fit. Now slide parallel to the crossbar through all slots or Bores 84 in the counters 8 a rod, preferably a steel rod 85, so all counters 8 are secured against rotation relative to one another. In order for this to take place with as little play as possible, the steel rod 85 should be fitted into the bores 84 in the housings 81 with a snug fit.
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 ent­ sprechend 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 only ent according to the wear of the squeegee that has yet to be readjusted. 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.
