Abstract

A ductor for a printing press having a rounded ductor profile ( 3 ) is distinguished by the fact that the radius of curvature of the ductor profile ( 3 ) is greater at the point ( 10 ) which corresponds to the ductor angle (alpha) than at a tangent point ( 11 ) which lies 20° further towards the tip and smaller than at a tangent point ( 12 ) which lies 15° further towards the flank.

Description

Die Erfindung betrifft ein Rakel für eine Druckmaschine mit einem abgerundeten Rakelprofil. Das Rakelprofil ist die Querschnittsform des an einer Walze anzuliegen bestimmten Randes des Rakels. Bei einem bekannten Rakel ( DE-2110299 A ) ist das Rakelprofil einseitig abgerundet ausgebildet. Der gegen die Walze anstellbare Teil des Rakels ist im Abstreifbereich mit einem gegen die Walze konvex gekrümmten Querschnitt ausgebildet. Der Rakelspalt verengt sich dadurch allmählich im Einlauf und erweitert sich sanft im Auslauf. Dadurch soll erreicht werden, daß störende Partikeln, insbesondere Farb- und Papierstaub durch die Engstelle mitgerissen werden und sich nicht störend vor dem Rakel ablagern können. Dieses Rakel scheint niemals praktisch angewendet worden zu sein. Das mag damit zusammenhängen, daß störende Ablagerungen auf einfachere Weise wirksam verhindert werden können.The invention relates to a squeegee for a printing press with a rounded squeegee profile. The squeegee profile is the cross-sectional shape of the edge of the squeegee to be abutted against a roller. In a known doctor blade ( DE-2110299 A ), the doctor blade profile is rounded on one side. The engageable against the roller part of the doctor blade is formed in the stripping region with a convex against the roller cross-section. The squeegee gap gradually narrows in the inlet and gently expands in the outlet. This is intended to ensure that disturbing particles, in particular paint and paper dust are entrained by the bottleneck and can not be distracting deposit before the doctor. This squeegee never seems to have been put to practical use. This may be related to the fact that disturbing deposits can be effectively prevented in a simpler way.

Die Erfindung hat jedoch erkannt, daß sich durch die Abrundung des Rakelprofils eine andere wichtige Aufgabe lösen läßt, nämlich ein schnelles, konstantes Anrakeln zu erreichen. Dies gelingt dadurch, daß bei einem Rakelwinkel zwischen etwa 20 und 40° der Krümmungswinkel des Rakelprofils von der Spitze zur Flanke hin zunimmt. Bei dem dem Rakelwinkel entsprechenden Tangentenpunkt ist der Krümmungsradius größer als bei dem Tangentenpunkt, der einem um 20° größeren Rakelwinkel entspricht und kleiner als bei dem Tangentenpunkt der einem um 15° kleineren Rakelwinkel entspricht. Bei einer bevorzugten Ausführungsform, die für einen Rakelwinkel um 30° vorgesehen ist, ist der Krümmungsradius des Rakelprofils am 30°-Tangentenpunkt größer als am 50°-Tangentenpunkt und kleiner als am 15°-Tangentenpunkt. Vorzugsweise ist er größer als am 40°-Tangentenpunkt und/oder kleiner als am 20°-Tangentenpunkt. Unter dem Tangentenpunkt zu einem bestimmten Winkel ist derjenige Punkt des Profils zu verstehen, an dem eine Tangente anliegt, die diesen Winkel mit der Mittelachse des Profils einschließt. Bei dem Winkel handelt es sich um denjenigen Winkel, unter welchem das Rakel gegenüber der Tangente im Berührungspunkt der Walzenoberfläche angestellt istHowever, the invention has recognized that can be solved by the rounding of the doctor blade another important task, namely to achieve a fast, constant Anrakeln. This is achieved in that increases at a doctor angle between about 20 and 40 °, the angle of curvature of the doctor blade profile from the tip to the flank. At the tangent point corresponding to the doctor angle, the radius of curvature is larger than at the tangent point, which corresponds to a doctor blade angle greater by 20 ° and smaller than at the tangent point corresponds to a doctor blade angle smaller by 15 °. In a preferred embodiment provided for a squeegee angle of 30 °, the radius of curvature of the squeegee profile at the 30 ° tangent point is greater than at the 50 ° tangent point and less than at the 15 ° tangent point. Preferably, it is greater than at the 40 ° tangent point and / or less than at the 20 ° tangent point. By the tangent point to a certain angle is meant the point of the profile against which there is a tangent which encloses this angle with the central axis of the profile. The angle is the angle at which the doctor is set against the tangent at the contact point of the roll surface

Der Krümmungsradius im 30°-Tangentenpunkt liegt zweckmäßigerweise zwischen der halben und der dreifachen Dicke des Rakelblechs, vorzugsweise zwischen der 0,8- und 2-fachen und weiter vorzugsweise zwischen der 1- und 1,5-fachen Dicke. Die Krümmungsradien im 50°-, 30°- und 15°-Tangentenpunkt verhalten sich vorzugsweise wie (0,4 bis 0,7) zu 1 zu (1,5 bis 4).The radius of curvature in the 30 ° tangent point is suitably between half and three times the thickness of the doctor blade, preferably between 0.8 and 2 times and more preferably between 1 and 1.5 times the thickness. The radii of curvature in the 50 °, 30 ° and 15 ° -tangent points preferably behave as (0.4 to 0.7) to 1 (1.5 to 4).

Das erfindungsgemäße Rakelprofil gestattet es, auf eine Dünnschlifflamelle zu verzichten. Darunter versteht man ein Rakelprofil, das von einem Abschnitt mit einer im wesentlichen konstanten, aber wesentlich geringeren Dicke gebildet ist als das übrige Rakelmesser. Sie hat den Nachteil, daß sie aufwendig in der Herstellung ist und in manchen Anwendungsfälle die Elastizitätseigenschaften des Rakels und das Anrakeln ungünstig beeinflußt. Das erfindungsgemäße Rakel zeichnet sich demgegenüber vorteilhafterweise dadurch aus, daß die Dicke des Rakelmessers von der Einspannstelle bis zum Rakelprofil durchgehend gleich ist.The doctor blade according to the invention makes it possible to dispense with a thin-grinding blade. This is understood to mean a doctor blade profile which is formed by a section with a substantially constant but substantially smaller thickness than the rest of the doctor blade. It has the disadvantage that it is expensive to produce and, in some applications, adversely affects the elastic properties of the doctor and the doctoring. The doctor blade according to the invention is advantageously characterized by that the thickness of the doctor blade from the clamping point to the doctor blade profile is the same.

Nach einem besonderen Merkmal der Erfindung ist das Rakelprofil beidseitig symmetrisch ausgebildet. Dadurch werden die Fehler vermieden, die bei unsymmetrischem Rakelprofil mitunter durch verkehrtes Einsetzen des Rakels vorkommen. Es kann auch von Interesse sein, ein bereits auf einer Seite benutztes Rakel zu wenden und mit der anderen Seite noch einmal zu benutzen.According to a particular feature of the invention, the doctor blade profile is symmetrical on both sides. This avoids the errors that sometimes occur with asymmetrical doctor blade profile by incorrect insertion of the doctor blade. It may also be of interest to turn a squeegee already used on one side and use it again with the other side.

Die Formung des Profils kann beispielsweise durch Schleifen oder Funkenerosion erfolgen.The shaping of the profile can be done for example by grinding or spark erosion.

Es wurde festgestellt, daß das erfindungsgemäße Rakel beim Einsatz in einer Kammerrakelvorrichtung zu einem besseren Farbeinschluß in der Kammer und zu einem geringeren Ablegen der Farbe führt.It has been found that the doctor blade according to the invention, when used in a chamber doctor blade device, leads to a better ink inclusion in the chamber and to a lower deposition of the ink.

Die Erfindung wird im folgenden näher unter Bezugnahme auf die Zeichnung erläutert, die ein vorteilhaftes Ausführungsbeispiel veranschaulicht. Es zeigen:

The invention will be explained in more detail below with reference to the drawing, which illustrates an advantageous embodiment. Show it:

the application in a doctor blade chamber.

Das Rakel 1, das in der Regel aus federndem Metall besteht und eine Dicke von beispielsweise 0,1 mm hat, besitzt einen Endabschnitt oder Rand 2, der zur Anlage an der Oberfläche einer Walze 4 bestimmt ist. Das Rakel ist beispielsweise an einer Kammerrakel 5 für Flexo-Druck angeordnet. Das Rakelprofil 3 zeichnet sich erfindungsgemäß dadurch aus, daß sein Krümmungsradius in demjenigen Bereich 6, in welchem es zur Anlage des Rakelmessers an der Oberfläche der Walze 4 kommen kann, von der Spitze 7 zur Flanke 8 hin zunimmt.Die Rakeldicke ist zweckmäßigerweise im übrigen konstant. Sie liegt im allgemeinen in der Größenordnung von 0,1 bis 0,3 mmThe doctor blade 1, which is usually made of resilient metal and has a thickness of, for example, 0.1 mm, has an end portion or edge 2 which is intended to bear against the surface of a roller 4. The doctor blade is arranged, for example, on a chambered doctor blade 5 for flexographic printing. The doctor blade profile 3 according to the invention is characterized in that its radius of curvature in that region 6, in which it is for the installation of the doctor blade on the surface of the roll 4th can come from the top 7 to flank 8 increases. The doctor blade thickness is expediently otherwise constant. It is generally of the order of 0.1 to 0.3 mm

Der üblicherweise bevorzugte Rakelwinkel, das ist der Winkel Alpha, unter welchem das Rakel 1 gegenüber der Walzentangente 9 im Berührungspunkt angestellt ist, wird häufig in der Größenordnung von 30° gewählt. In diesem Fall liegt das Rakelprofil im Neuzustand mit seinem Punkt 10 an der Walzenoberfläche 3 an. Dieser Punkt wird hier als 30°-Tangentenpunkt bezeichnet. Der Krümmungsradius des Profils in diesem Punkt ist größer als in jedem innerhalb des Bereichts 6 näher zur Spitze 7 hin liegenden Punkt. Er ist insbesondere größer als im 50°-Tangentenpunkt 11 und kleiner als im 15°-Tangentenpunkt 12. Vorzugsweise ist er größer als in dem (nicht dargestellten) 40°-Tangentenpunkt und/oder kleiner als am (nicht gezeigten) 20°-Tangentenpunkt. Vorzugsweise vollzieht sich die Änderung des Krümmungsradius kontinuierlich. Jedoch ist dies nicht unbedingt erforderlich.The usually preferred doctor angle, that is the angle alpha at which the doctor blade 1 is set opposite the roller tangent 9 at the point of contact, is often chosen to be on the order of 30 °. In this case, the doctor blade is in the new state with its point 10 on the roll surface 3 at. This point is referred to here as the 30 ° tangent point. The radius of curvature of the profile at this point is greater than in each point within the region 6 closer to the tip 7 point. It is in particular larger than in the 50 ° tangent point 11 and smaller than in the 15 ° tangent point 12. It is preferably larger than in the 40 ° tangent point (not shown) and / or smaller than at the 20 ° tangent point (not shown) , Preferably, the change of the radius of curvature takes place continuously. However, this is not essential.

Je kleiner der Rakelwinkel ist, umso größer bildet sich später nach Materialabtrag vom Rakelmesser dessen an der Walzenoberfläche 3 anliegende Fase aus. Um so größer ist bei Wahl des erfindungsgemäßen Rakelprofils auch derjenige Oberflächenbereich des Rakelmessers, der im Anfangszustand der Walzenoberfläche unmittelbar nahe ist. Um so geringer ist der Unterschied zwischen der Form des Rakelprofils im Neuzustand und im späteren Zustand. Um so geringer ist auch der Unterschied in der Rakelwirkung. Daraus ergibt sich ein schnelles Anrakeln ohne wesentliche Änderung der Druckqualität. Da dies ohne Dünnschliff erreicht wird, erhält man auch eine hohe Stabilität im Arbeitsbereich ohne die bei einer herkömmlichen Dünnschlifflamelle auftretende Durchbiegung.The smaller the squeegee angle is, the larger the shape of the chamfer adjoining the roll surface 3 forms later on after material removal from the doctor blade. The greater is the choice of the doctor blade according to the invention, the one surface area of the doctor blade, which is in the initial state of the roll surface immediately close. The smaller the difference between the shape of the squeegee profile when new and later. The smaller the difference in the squeegee effect. This results in a quick Anrakeln without significant change in print quality. Since this is achieved without thin section, you get also a high stability in the work area without the deflection occurring in a conventional thin-fluted lamella.

Infolge der symmetrischen Gestalt des Rakelprofils braucht beim Einsetzen des Rakelmessers nicht auf dessen Ausrichtung geachtet zu werden. Dies vereinfacht die Montage und verhütet Fehler durch Fehlausrichtung.Due to the symmetrical shape of the doctor blade does not need to be paid attention to its orientation when inserting the doctor blade. This simplifies assembly and prevents errors due to misalignment.
