Description

Die Erfindung betrifft eine Rakelvorrichtung nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a doctor device according to the preamble of claim 1.

Bei einer aus der DE-OS 19 41 595 bekannten Rakelvorrichtung für eine Tiefdruckmaschine ist der Rakelhalter an einem Rakelträger auf einem Kreisbogen schwenkbar, dessen Mittelpunkt in der Schneide des Rakelmessers liegt, so daß bei einem Verschwenken des Rakelhalters zwar der Anstellwinkel des Rakelmessers zu dem Formzylinder geändert wird, aber die Berührungslinie des Rakelmessers mit dem Formzylinder unverändert beibehalten wird.In a squeegee device known from DE-OS 19 41 595 for a gravure printing machine, the squeegee holder can be pivoted on a squeegee carrier on a circular arc, the center of which lies in the cutting edge of the squeegee knife, so that when the squeegee holder is pivoted, the angle of attack of the squeegee knife to the forme cylinder is changed, but the line of contact of the doctor blade with the forme cylinder is retained unchanged.

Werden Farben unterschiedlicher Viskosität und mit unterschiedlichem Trocknungsverhalten bearbeitet, ist nicht nur der Anstellwinkel der Rakel an dem Zylinder bzw. dem Formzylinder wichtig, sondern insbesondere auch die Lage der Berührungslinie der Rakelmesserschneide an dem Formzylinder, da durch diese die Trocknung der Farbe beeinflußt werden kann. Während also die Lage der Berührungslinie der Rakel mit dem Formzylinder den Trocknungsgrad beeinflußt, hängt der Füllgrad der Näpfchen des Formzylinders mit Farbe von dem Anstellwinkel des Rakelmessers ab. Um ein gutes Druckergebnis zu erzielen, muß daher nicht nur der Anstellwinkel des Rakelmessers eingestellt werden, und zwar bereits beim Andrucken.If colors of different viscosity and with different drying behavior are processed, not only the angle of attack of the squeegee on the cylinder or the forme cylinder is important, but also in particular the position of the line of contact of the doctor blade edge on the form cylinder, since this can influence the drying of the ink. So while the position of the line of contact of the doctor blade with the forme cylinder influences the degree of dryness, the degree of filling of the cups of the forme cylinder with ink depends on the angle of attack of the doctor blade. In order to achieve a good printing result, it is therefore not only necessary to set the angle of attack of the doctor blade, and indeed already during the printing.

Bei einer aus US-A-3,780,670 bekannten Rakelvorrichtung nach dem Oberbegriff des Patentanspruchs 1 sind von Hand betätigbare Räder vorgesehen, über die sich die Einstellungen des Rakelhalters, des den Rakelhalter lagernden Rahmens und der Tragstücke des Rahmens vornehmen lassen. Die Einstellungen von Hand erschweren es jedoch, den Anstellwinkel und die Angriffslinie des Rakelmessers an der Walze und zusätzlich auch den Anstelldruck des Rakelmessers an die Walze zuverlässig, feinfühlig und schnell, insbesondere auch während des Druckbetriebes, einzustellen.In a squeegee device known from US-A-3,780,670 according to the preamble of claim 1, manually operable wheels are provided, via which the settings of the squeegee holder, the frame supporting the squeegee holder and the supporting pieces of the frame can be carried out. The manual settings make it more difficult, however, the angle of attack and the line of attack of the doctor blade on the roller and also the pressure of the Doctor blade knife on the roller reliably, sensitively and quickly, especially during printing.

Aufgabe der Erfindung ist es daher, eine Rakelvorrichtung nach dem Oberbegriff des Patentanspruchs 1 zu schaffen, mit der sich die erforderlichen Einstellungen des Rakelmessers feinfühlig und schnell einstellen lassen.The object of the invention is therefore to provide a doctor device according to the preamble of claim 1, with which the required settings of the doctor knife can be adjusted sensitively and quickly.

Erfindungsgemäß wird diese Aufgabe durch die kennzeichnenden Merkmale des Patentanspruchs 1 gelöst. Bei der erfindungsgemäßen Rakelvorrichtung kann der Rakelhalter durch Betätigung der Antriebe parallel zu sich selbst linear verfahren werden und zusätzlich Schwenkbewegungen um zwei Parallele und im Abstand voneinander angeordnete Schwenkachsen ausführen, so daß das Rakelmesser automatisch oder durch Fernbedienung unter beliebig wählbaren Winkeln und in einem vorgegebenen Umfangsbereich der Walze in unterschiedlichen Lagen an diese angestellt werden kann, wobei sich zusätzlich auch durch die Antriebe der Andruck des Rakelmessers steuern läßt. Die erfindungsgemäße Rakelvorrichtung gestattet es somit, insbesondere auch während des Druckbetriebes, den Füllgrad der Näpfchen des Formzylinders und die Antrocknungszeit der Farbe feinfühlig durch eine Fernbedienung, die eine Beobachtung der Rakelvorrichtung insgesamt zuläßt, zu verändern. Damit ist es möglich, unabhängig von dem Trocknungsverhalten der jeweils verarbeiteten Farbe ein optimales Druckergebnis zu erzielen.According to the invention, this object is achieved by the characterizing features of patent claim 1. In the squeegee device according to the invention, the squeegee holder can be moved linearly parallel to itself by actuating the drives and additionally perform swiveling movements around two parallel and spaced-apart swivel axes, so that the squeegee knife can be operated automatically or by remote control at arbitrary angles and within a predetermined circumferential range Roller in different positions can be placed against them, and the pressure of the doctor blade can also be controlled by the drives. The squeegee device according to the invention thus makes it possible to change the filling level of the wells of the forme cylinder and the drying time of the ink sensitively by means of a remote control, which permits observation of the squeegee device as a whole, in particular even during printing operation. This makes it possible to achieve an optimal printing result regardless of the drying behavior of the ink processed.

Bei der zentralen Steuereinrichtung handelt es sich zweckmäßigerweise um einen zentralen Rechner, der entsprechend dem jeweiligen Programm die Schwenk- und Linearantriebe steuert.The central control device is expediently a central computer which controls the swivel and linear drives in accordance with the respective program.

Ein weiterer Vorteil der erfindungsgemäßen Rakelvorrichtung besteht darin, daß sich diese automatisch auch auf unterschiedliche Durchmesser der Walzen und Formzylinder einstellen läßt.Another advantage of the doctor device according to the invention is that it automatically changes to different Can adjust the diameter of the rollers and forme cylinders.

Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche 2 und 3.Advantageous embodiments of the invention are the subject of dependent claims 2 and 3.

Zwei Seitenwände des Gestells sind mittels einer Quertraverse 2 miteinander verbunden. Mit den Innenseiten einer jeden Seitenwand 1 sind Getriebe 3 und 4 verschraubt, wobei dem Getriebe 4 ein Motor 5 zugeordnet ist. Über eine Welle 6 sind die Getriebe 3 und 4 miteinander verbunden. Die vom Motor 5 über die Getriebe 3 und 4 antreibbaren Gewindespindeln 7 und 8 sind im Bereich ihrer von den Getrieben 3 und 4 entfernt liegenden Enden über mit den Seitenwänden 1 verbundenen Konsolen 9 und 10 gehalten. Auf die Gewindespindeln 7 und 8 sind mit nicht dargestellten Gewindemuttern ausgestattete Lager 11 und 12 aufgesetzt. In dem auf der linken Seite der Figur 1 dargestellten Lager 11 ist ein Lagerzapfen 13 drehbar gehalten, der mit einer Seite eines Gußrahmens 14 fest verbunden ist. Ebenso wie in dem Lager 11 ist auch in dem auf der rechten Seite der Figur 1 dargestellten Lager ein Lagerzapfen 15 drehbar gelagert, der an seinem dem Lager 12 abgewandten Ende mit der rechten Seite des Gußrahmens 14 fest verbunden ist. Auf den in der Figur 1 rechts dargestellten Lagerzapfen 15 ist ein Klemmhebel 16 aufgesetzt, der an seiner in Figur 3 dem Betrachter zugewandten Seite gabelförmig ausgebildet ist. In den beiden Gabelarmen 17 und 18 ist ein Bolzen 19 drehbar gelagert, der eine mittige Gewindebohrung aufweist. In diese Gewindebohrung ist eine Gewindespindel 21 eingeschraubt, die an ihrem unteren Ende (Figur 1) ein Gelenk 22 aufweist. Über dieses Gelenk 22 ist die Gewindespindel 21 mit einem Wellenstummel 23 verbunden, der in einem Tragprofil 24 axial fest aber drehbar gelagert ist. Auf das dem Gelenk 22 entfernt liegenden Ende des Wellenstummels 23 ist eine Riemenscheibe 25 aufgesetzt, die über einen Keilriemen 26 mit einer weiteren Riemenscheibe 27 verbunden ist. Letztere, nämlich die Riemenscheibe 27, ist über einen Motor 28 antreibbar, der mit dem Tragprofil 24 fest verbunden ist. Das Tragprofil 24 selbst ist an dem Lager 12 befestigt.Two side walls of the frame are connected to one another by means of a crossbar 2. With the inside of each Side wall 1, gears 3 and 4 are screwed, with gear 4 being assigned a motor 5. The gears 3 and 4 are connected to one another via a shaft 6. The threaded spindles 7 and 8 which can be driven by the motor 5 via the gears 3 and 4 are held in the region of their ends remote from the gears 3 and 4 via brackets 9 and 10 connected to the side walls 1. Bearings 11 and 12 equipped with threaded nuts, not shown, are placed on the threaded spindles 7 and 8. In the bearing 11 shown on the left side of FIG. 1, a bearing journal 13 is rotatably held, which is firmly connected to one side of a cast frame 14. Just as in the bearing 11, a bearing journal 15 is rotatably mounted in the bearing shown on the right-hand side of FIG. 1 and is fixedly connected to the right-hand side of the cast frame 14 at its end facing away from the bearing 12. A clamping lever 16 is placed on the bearing pin 15 shown on the right in FIG. 1 and is fork-shaped on its side facing the viewer in FIG. 3. In the two fork arms 17 and 18, a bolt 19 is rotatably mounted, which has a central threaded bore. A threaded spindle 21 is screwed into this threaded bore and has a joint 22 at its lower end (FIG. 1). About this joint 22, the threaded spindle 21 is connected to a stub shaft 23 which is axially fixed but rotatable in a support profile 24. A pulley 25, which is connected to a further pulley 27 by means of a V-belt 26, is placed on the end of the shaft end 23 that is distant from the joint 22. The latter, namely the pulley 27, can be driven by a motor 28 which is firmly connected to the support profile 24. The support profile 24 itself is attached to the bearing 12.

Durch Einschalten des Motors 5 können demzufolge die beiden Lager 11 und 12 hoch- und heruntergefahren werden, wodurch über die Lagerzapfen 13 und 15 auch der Gußrahmen 14 angehoben bzw. abgesenkt werden kann. Durch zusätzliches Einschalten des Motors 28 (Figur 3) kann der Gußrahmen 14 zusätzlich noch über die Gewindespindel 21, den Bolzen 19 und den Klemmhebel 16 verschwenkt werden.By turning on the motor 5, the two bearings 11 and 12 can consequently be raised and lowered, thereby over the journals 13 and 15, the cast frame 14 can be raised or lowered. By additionally switching on the motor 28 (FIG. 3), the cast frame 14 can additionally be pivoted via the threaded spindle 21, the bolt 19 and the clamping lever 16.

Der Gußrahmen 14 weist mehrere mit Abstand voneinander angeordnete Stützen 29 auf, wobei jeweils zwei Stützen 29 eine Achse 30 tragen. Auf den drei Achsen 30 lagern Arme 31, die mit dem eigentlichen Rakelhalter 32 fest verbunden sind. Wie die Figur 1 erkennen läßt, ist and den Gußrahmen 14 ein weiterer Motor 33 angeflanscht, über den der Rakelhalter 32 gegenüber dem Grundrahmen 14 verschwenkt werden kann. Diese Verschwenkung geschieht in analoger Weise zu der Verschwenkung des Gußrahmens 14 über den Motor 28, so daß sich eine weitere Erläuterung erübrigt.The cast frame 14 has a plurality of supports 29 which are arranged at a distance from one another, two supports 29 each carrying an axis 30. Arms 31, which are firmly connected to the actual doctor holder 32, are supported on the three axes 30. As can be seen in FIG. 1, a further motor 33 is flanged to the cast frame 14, by means of which the doctor holder 32 can be pivoted relative to the base frame 14. This pivoting takes place in an analogous manner to the pivoting of the cast frame 14 via the motor 28, so that a further explanation is unnecessary.

In der Figur 2 sind ein Formzylinder 34 und ein Presseur 35 jeweils mit vollen Linien dargestellt. An den Formzylinder 34 ist das Rakelmesser 36 angestellt, welches über Klemmstücke 37 und einer Spannpratze 38 mit dem Rakelhalter 32 verbunden ist. Durch entsprechendes Anfahren der Motore 5,28 und 33 kann zum einen das Rakelmesser den Winkel B durchfahren, der Einfluß auf den Trocknungsgrad der Farbe hat. (Je weiter das Rakelmesser vom Presseur entfernt ist, desto weiter ist der Weg, den die abgerakelten Näpfchen des Formzylinders zum Presseur zurücklegen müssen, wodurch ein hoher Trocknungsgrad erzielt wird). Weiterhin kann durch entsprechendes Verfahren der genannten drei Motore das Rakelmesser innerhalb des Winkels A eingestellt werden, durch den der Näpfchenfüllgrad definiert wird. (Je kleiner der Winkel A ist, desto größer ist der Füllgrad der Näpfchen).A forme cylinder 34 and an impression roller 35 are shown in full lines in FIG. The doctor blade 36 is attached to the forme cylinder 34 and is connected to the doctor holder 32 via clamping pieces 37 and a clamping claw 38. By appropriately starting the motors 5, 28 and 33, the doctor blade can pass through the angle B, which has an influence on the degree of drying of the ink. (The farther the doctor blade is from the impression roller, the farther the path that the scraped cups of the forme cylinder have to travel to the impression roller, whereby a high degree of drying is achieved). Furthermore, the doctor blade can be adjusted within the angle A by a corresponding method of the three motors mentioned, by which the degree of cell filling is defined. (The smaller the angle A, the greater the degree of filling of the cells).

In Fig. 4 ist ein Blockschaltbild der NC-Steuerung der Rakelvorrichtung dargestellt. Kern der Steuereinrichtung ist ein Rechner, der die Stellmotore 5,28,33 steuert. Durch spezielle Programme läßt sich der Anstellwinkel und die Anstellinie sowie der Anstelldruck des Rakelmessers zum Formzylinder steuern. Weiterhin sind spezielle Programme vorhanden, die das Rakelmesser bei einem Wechsel des Formzylinders automatisch auf einen geänderten Formzylinderdurchmesser einstellen.FIG. 4 shows a block diagram of the NC control of the doctor device. The core of the control device is a computer that controls the servomotors 5, 28, 33. The angle of attack and the line of attack as well as the pressure of the doctor blade to the forme cylinder can be controlled by special programs. There are also special programs that automatically adjust the doctor blade to a changed forme cylinder diameter when changing the forme cylinder.

Die Programme enthalten zusätzlich Programmteile für vorbestimmte Druckaufträge, so daß diese in einfacher Weise abgerufen werden können.The programs additionally contain program parts for predetermined print jobs so that they can be called up in a simple manner.
