Description

Die Erfindung betrifft ein Rakelfarbwerk für Druckmaschinen mit mindestens einem an eine Rasterwalze anstellbaren Kammerrakel, das mittels eines Trägers an einer parallel zur Rasterwalze angeordneten Traverse gelagert ist.The invention relates to a doctor blade inking unit for printing presses with at least one chambered doctor blade which can be set on an anilox roller and which is mounted on a crossbar arranged parallel to the anilox roller by means of a carrier.

Derartige Rakelfarbwerke sind aus dem Buch "Technik des Flexodrucks", erschienen im Coating Verlag Thomas & Co., beschrieben. Bei diesen Farbwerken ist die Kammerrakel mittels Schraubverbindungen an einer Traverse befestigt. Zum Auswechseln der Kammerrakel, beispielsweise bei einem Farbwechsel müssen daher Schraubverbindungen gelöst und wieder angezogen werden.Squeegee inking systems of this type are described in the book "Technik des Flexodrucks", published by Coating Verlag Thomas & Co. In these inking units, the chambered doctor blade is attached to a crossbar by means of screw connections. To replace the doctor blade, for example when changing colors, screw connections must therefore be loosened and tightened again.

Der Erfindung liegt die Aufgabe zugrunde, das individuelle oder gemeinsame Wechseln von mehreren nebeneinander angeordneten Kammerrakeln sowie deren An- und Abstellung zu vereinfachen und zu beschleunigen.The object of the invention is to simplify and accelerate the individual or joint replacement of a plurality of chamber doctor blades arranged next to one another as well as their starting and stopping.

Erfindungsgemäß wird diese Aufgabe durch Anwendung der Merkmale des Kennzeichens des Anspruchs 1 gelöst.According to the invention, this object is achieved by applying the features of the characterizing part of claim 1.

Bei der Anordnung gemäß Fig. 1 und 5 ist ein mit 1 bezeichnetes Kammerrakel vorgesehen, das mit einer Rasterwalze 2 zusammenwirkt. Das Kammerrakel 1 ist fest an einer Stirnplatte 3 eines insgesamt mit 4 bezeichneten Trägers verbunden, der zwei Klemmleisten 5 aufweist. An jeder Klemmleiste 5 sind fest zwei Bolzen 6, 7 angebracht, deren Längsachsen parallel zur Längsachse der Rasterwalze 2 verlaufen.In the arrangement according to FIGS. 1 and 5, a chambered doctor blade designated 1 is provided, which interacts with an anilox roller 2. The chambered doctor blade 1 is firmly connected to an end plate 3 of a support, generally designated 4, which has two clamping strips 5. Two bolts 6, 7 are permanently attached to each terminal strip 5, the longitudinal axes of which run parallel to the longitudinal axis of the anilox roller 2.

Zwischen Seitenwänden 8 der Druckmaschine ist gemäß Fig. 5 eine Traverse 9 befestigt, auf die zum Anschluß von Kammerrakeln 1 je zwei Kalter 10 aufgesetzt sind. Jeder einseitig geschlitzte Halter 10 ist mittels einer Klemmschraube 11 unverdrehbar und unverschiebbar auf der Traverse 9 festgelegt.5, a crossmember 9 is fastened between side walls 8 of the printing press, onto which two colders 10 are placed for connecting chambered doctor blades 1. Each holder 10 slotted on one side is fixed in a non-rotatable and immovable manner on the crossmember 9 by means of a clamping screw 11.

Jeder Halter 10 weist zwei Halteansätze 12, 13 auf. Der Halteansatz 12 ist mit einer unteren Auflagefläche 14 und auf der der Rasterwalze 2 abgewandten Seite mit einer Anschlagfläche 15 für den Bolzen 6 versehen, wobei der Bolzen 6 im Betriebszustand des Kammerrakels die Anschlagfläche 15 nicht berührt. Der der Rasterwalze 2 benachbarte Halteansatz 13 weist außer einer Auflagefläche 16 zwei einander gegenüberliegende Anlageflächen 17 und 18 für den Bolzen 7 auf. Die Anlagefläche 17 ist dabei jedoch nur so kurz bemessen, daß der Bolzen 7 durch Anheben vom Halteansatz 13 gelöst werden kann. Die Auflagefläche des Halteansatzes 12 kann gemäß Fig. 2 auch durch eine Auflagefläche 20 gebildet werden, die die Stirnfläche einer Stellschraube 19 ist. Durch Änderung der Position der Auflagefläche 20 kann eine individuelle Feinjustierung eines Kammerrakels 1 in seiner Lage gegenüber der Raterwalze 2 vorgenommen werden.Each holder 10 has two retaining lugs 12, 13. The retaining lug 12 is provided with a lower contact surface 14 and on the side facing away from the anilox roller 2 with a stop surface 15 for the bolt 6, the bolt 6 not touching the stop surface 15 in the operating state of the chamber doctor blade. The holding projection 13 adjacent to the anilox roller 2 has, in addition to a bearing surface 16, two mutually opposite bearing surfaces 17 and 18 for the bolt 7. The contact surface 17 is, however, only dimensioned so short that the bolt 7 can be released from the holding projection 13 by lifting it. According to FIG. 2, the contact surface of the holding projection 12 can also be formed by a contact surface 20 which the end face of a set screw 19. By changing the position of the support surface 20, an individual fine adjustment of a chamber doctor blade 1 in relation to the rater roller 2 can be carried out.

Zwischen dem Halter 10 und einem Sicherungsring 21 ist auf der Traverse 9 drehbar ein Spannelement 22 in Form eines Spannockens angeordnet. Am Spannelement 22 ist ein Handhebel 23 befestigt. Die Steigung des Spannockens ist dabei so gewählt, daß dieser selbsthemmend mit der Klemmleiste 5 zusammenwirkt. Zusätzlich kann im Spannocken ein Schlitz 24 vorgesehen sein, so daß die vom Spannelement 22 auf die Klemmleiste 5 aufgebrachte Kraft zum Teil durch die elastische Verformung dieses Teils bestimmt ist.A clamping element 22 in the form of a clamping cam is rotatably arranged on the crossmember 9 between the holder 10 and a securing ring 21. A hand lever 23 is attached to the tensioning element 22. The pitch of the clamping cam is chosen so that it interacts with the terminal strip 5 in a self-locking manner. In addition, a slot 24 can be provided in the clamping cam, so that the force applied by the clamping element 22 to the terminal strip 5 is determined in part by the elastic deformation of this part.

Fig. 1 zeigt die Anordnung in der Betriebsposition, in das Kammerrakel 1 an der Rasterwalze 2 anliegt. Soll das Kammerrakel 1 ausgewechselt werden, so werden die Handhebel 23 in Richtung des Pfeiles a bewegt. Hierdurch wird die Klemmkraft, die auf die Klemmleisten 5 wirkt, aufgehoben. Der Träger 4 mit der Kammerrakel 1 kann sich nunmehr geringfügig um die Achse der Bolzen 7 in Richtung des Pfeiles b drehen, bis die Bolzen 6 zur Anlage an den Anschlagflächen 15 kommen, da der Schwerpunkt des mit dem Träger 4 fest verbundenen Kammerrakel 1 zwischen den Bolzen 7 und der Rasterwalze 2 liegt. Hierbei hebt das Kammerrakel 1 von der Rasterwalze geringfügig ab. Diese Position ist dementsprechend auch für kurze Betriebsunterbrechungen geeignet. Zweckmäßig weisen die Spannelemente 22 zur Definition der Wechselposition je eine Abflachung 25 auf, die der zugeordneten Klemmleiste 5 gegenüberzustellen ist. Das durch die Lage des Schwerpunkts des Kammerrakels 1 bedingte leichte Abschwenken des Kammerrakels 1 von der Rasterwalze 2 kann gemäß Fig. 3 auch durch Federn 26 unterstützt werden, die zwischen Kalteansatz 12 und Bolzen 6 wirken.Fig. 1 shows the arrangement in the operating position, in which chamber doctor blade 1 rests on the anilox roller 2. If the chambered doctor blade 1 is to be replaced, the hand levers 23 are moved in the direction of arrow a. As a result, the clamping force acting on the terminal strips 5 is canceled. The carrier 4 with the chamber doctor 1 can now rotate slightly about the axis of the bolts 7 in the direction of arrow b until the bolts 6 come to rest against the stop surfaces 15, since the center of gravity of the chamber doctor 1 firmly connected to the carrier 4 between the Bolt 7 and the anilox roller 2 is. Here, the doctor blade 1 lifts slightly from the anilox roller. This position is also suitable for short business interruptions. Expediently, the clamping elements 22 each have a flattening 25 for defining the changing position, which is to be compared to the assigned terminal strip 5. The slight swiveling of the chambered doctor blade 1 from the anilox roller 2 due to the position of the center of gravity of the chambered doctor blade 1 can also be supported according to FIG. 3 by springs 26 which act between the cold shoulder 12 and the bolt 6.

In der so erreichten Position kann das Kammerrakel ausgewechselt werden. Hierzu wird das Kammerrakel 1 mit dem Träger 4 zunächst so bewegt, daß die Bolzen 7 über die Anlageflächen 17 angehoben werden. Anschließend werden die Teile 1 und 4 in Richtung des Pfeiles c bewegt, so daß die Bolzen 6 und 7 von den Halteansätzen 12 und 13 wegbewegt werden.The chambered doctor blade can be replaced in the position reached in this way. For this purpose, the doctor blade 1 with the carrier 4 is initially so moves that the bolts 7 are raised over the contact surfaces 17. The parts 1 and 4 are then moved in the direction of arrow c, so that the bolts 6 and 7 are moved away from the retaining lugs 12 and 13.

Das Einhängen eines neuen Kammerrakels erfolgt in umgekehrter Weise. Es werden also zunächst die Bolzen 7 schräg von oben zwischen die Anlageflächen 17, 18 geführt bis sie an der Auflagefläche 16 zur Anlage kommen. Anschließend werden die Handhebel 23 entgegen der Richtung des Pfeiles a bewegt. Hierdurch drücken die Spannelemente 22 die Bolzen 6 und 7 über die Klemmleisten 5 gegen die Auflageflächen 14 und 16 und fixieren somit das Kammerrakel 1 in der Betriebsposition. Das Wechseln eines Kammerrakels 1 kann somit in einfacher Weise, ohne Lösen von Schraubverbindungen durch Betätigen der Spannelemente und Aushängen der Bolzen 6, 7 erfolgen.The insertion of a new chamber doctor blade takes place in the opposite way. So first the bolts 7 are guided obliquely from above between the contact surfaces 17, 18 until they come to rest on the contact surface 16. The hand levers 23 are then moved counter to the direction of arrow a. As a result, the clamping elements 22 press the bolts 6 and 7 against the contact surfaces 14 and 16 via the terminal strips 5 and thus fix the chambered doctor blade 1 in the operating position. Changing a chambered doctor blade 1 can thus be carried out in a simple manner, without loosening screw connections, by actuating the tensioning elements and unhooking the bolts 6, 7.

Eine Erleichterung der Drehung des Bolzens 7 bei Betätigung des Spannelementes 22 läßt sich dadurch erreichen, daß anstelle des Halteansatzes 13 ein Halteansatz 27 gemäß Fig. 4 Verwendung findet. Bei diesem Halteansatz sind die Auflagefläche 16 und die Anlageflächen 17 und 18 des Halteansatzes 13 zu einer einzigen lagerschalenartig gebogenen Fläche 28 zusammengefaßt, wobei der Radius der gebogenen Fläche 28 etwa dem Radius des Bolzens 7 entspricht.The rotation of the bolt 7 when the tensioning element 22 is actuated can be facilitated by using a retaining projection 27 according to FIG. 4 instead of the retaining projection 13. In this holding approach, the bearing surface 16 and the contact surfaces 17 and 18 of the holding projection 13 are combined into a single bearing shell-like curved surface 28, the radius of the curved surface 28 corresponding approximately to the radius of the bolt 7.

Beim dargestellten Ausführungsbeispiel können mehrere Kammerrakeln 1 nebeneinander angeordnet sein, dann sind jedem Kammerrakel zwei Halter 10 mit Spannelementen 22 zugeordnet. Dennoch kann auch bei einer derartigen Anordnung ein sich über die ganze Länge der Rasterwalze erstreckendes Kammerrakel zum Einsatz kommen, da ein breites Kammerrakel ebenfalls nur zwei Klemmleisten mit Bolzen 6, 7 trägt, die dann nur an zwei Haltern eingehängt werden, während die übrigen Halter außer Betrieb verbleiben. Bei Verwendung mehrerer schmaler Kammerrakel 1 und Verwendung einer mittig angeordneten Klemmleiste kann es ausreichen, wenn nur ein Halter pro Kammerrakel vorgesehen ist.In the illustrated embodiment, a plurality of chamber doctor blades 1 can be arranged side by side, then two holders 10 with clamping elements 22 are assigned to each chamber doctor blade. Nevertheless, even with such an arrangement, a chamber squeegee extending over the entire length of the anilox roller can be used, since a wide chamber squeegee also carries only two clamping strips with bolts 6, 7, which are then only attached to two holders, while the other holders are excluded Operation remain. When using several narrow chamber doctor blades 1 and using a centrally arranged clamping strip, it may be sufficient if only one holder is provided per chamber doctor blade.

Um bei längeren Betriebsunterbrechungen das Kammerrakel 1 weiter von der Rasterwalze 2 abstellen zu können, ist die Traverse 9 als ganzes in der Seitenwand 8 drehbar gelagert. Die Drehung der Traverse 9 kann gemäß Fig. 6 über einen fest mit der Traverse verbundenen Stellarm 29, auf den über eine Stellstange 30 eine Stelleinrichtung 31 wirkt, erfolgen. Die Stelleinrichtung kann aus hydraulisch oder pneumatisch betätigten Stellzylindern oder Elektromagneten bzw. Elektromotoren aufgebaut sein. Eine vorhergehende Drehung der Traverse 9 erleichtert auch das Auswechseln der Kammerrakel.In order to be able to place the doctor blade 1 further away from the anilox roller 2 during longer interruptions in operation, the crossmember 9 as a whole is rotatably mounted in the side wall 8. According to FIG. 6, the crossmember 9 can be rotated via an actuating arm 29 which is firmly connected to the crossmember and on which an actuating device 31 acts via an actuating rod 30. The actuating device can be constructed from hydraulically or pneumatically actuated actuating cylinders or electromagnets or electric motors. A previous rotation of the traverse 9 also facilitates the replacement of the chamber doctor.

Um bei Anordnung von mehr als zwei Haltern 10 auf der Traverse auch lediglich eine der vorhandenen plattenbreiten Kammerrakel 1 weit von der Rasterwalze abstellen zu können, ist gemäß Fig. 7 und 8 vorgesehen, eine Traverse 32 aus einer zentralen fest an Seitenwänden 8 angeschlossenen Achse 33 und mehreren Hohlwellen 34, 35 auszubilden. Die Hohlwellen 34, 35 sind dabei untereinander und gegenüber der Achse 33 frei drehbar gelagert. Jede der beiden Hohlwellen 34, 35 ist gemäß Fig. 8 fest mit einem Stellarm 36 bzw. 37 verbunden, an dem je eine Stellstange 38 bzw. 39 eine Stelleinrichtung 40 bzw. 41 angreift. Dabei trägt jede der beiden Hohlwellen 34, 35 je zwei Halter 10, die in Fig. 8 nur schematisch angedeutet sind und denen wiederum je ein Spannelement 22 zugeordnet ist. Es besteht daher die Möglichkeit, beispielsweise über den Stellzylinder 41 lediglich die an den Haltern 10 der Hohlwelle 35 angeschlossene Kammerrakel abzustellen.In order to be able to park only one of the existing plate-wide chamber doctor blades 1 far from the anilox roller when more than two holders 10 are arranged on the cross member, a cross member 32 is provided according to FIGS. 7 and 8, from a central axis 33 firmly connected to side walls 8 and to form a plurality of hollow shafts 34, 35. The hollow shafts 34, 35 are freely rotatable with each other and with respect to the axis 33. 8, each of the two hollow shafts 34, 35 is fixedly connected to an actuating arm 36 or 37, on each of which an actuating rod 38 or 39 engages an actuating device 40 or 41. Each of the two hollow shafts 34, 35 carries two brackets 10, which are only indicated schematically in FIG. 8 and which in turn are each assigned a clamping element 22. It is therefore possible, for example, to switch off only the chamber doctor blade connected to the holders 10 of the hollow shaft 35 via the actuating cylinder 41.

Um einen Ausbau der Rasterwalze 2 zu erleichtern, kann, wie in Fig. 9 und 10 gezeigt, die Traverse 9 samt den zugehörigen Stelleinrichtungen 31 auf Platten 42 angebracht werden, die derart an den Seitenwänden 8 befestigt sind, daß beim Lösen eines Befestigungselementes 43 ein Abschwenken der Traverse von der Rasterwalze um eine Achse 44 in Richtung des Pfeiles d gemäß Fig. 10 möglich ist.In order to facilitate removal of the anilox roller 2, as shown in FIGS. 9 and 10, the traverse 9 together with the associated actuating devices 31 can be attached to plates 42 which are fastened to the side walls 8 in such a way that when a fastening element 43 is loosened a Swiveling of the traverse from the anilox roller about an axis 44 in the direction of arrow d according to FIG. 10 is possible.
