Es sind Kammerrakel bekannt (siehe z.B. EP-A-0359959), deren Rakelbalken festgeklemmt werden muß und deren Rakelblätter nachfolgend an eine Rasterwalze angestellt werden müssen. Dies ist technisch recht aufwendig.Chamber doctor blades are known (see e.g. EP-A-0359959), the doctor blade bars of which must be clamped and the doctor blade blades of which must subsequently be placed against an anilox roller. This is technically very complex.

Der Erfindung liegt die Aufgabe zugrunde, eine Einrichtung zum Anstellen eines Rakelbalkens an eine farbabgebende Walze einer Rollenrotationsdruckmaschine zu schaffen, die einfach zu Handhaben und mit welcher der Rakelbalken einfach zu befestigen und mit einfachen Mitteln an eine farbabgebende Walze anzustellen ist.The invention has for its object to provide a device for placing a squeegee on an inking roller of a web-fed rotary printing press, which is easy to use and with which the squeegee is easy to attach and can be easily adjusted to an inking roller.

Erfindungsgemäß wird diese Aufgabe durch den kennzeichnenden Teil des Patentanspruches 1 gelöst.According to the invention, this object is achieved by the characterizing part of patent claim 1.

Bei der Anwendung der Erfindung treten insbesondere folgende Vorteile auf: Beim Entfernen der Kammerrakel bzw. des Rakelbalkens aus der Halterung wird durch Verdrehen der Spannhebel in die Waagerechte eine Führung geschaffen, auf welcher der Rakelbalken in waagerechter Richtung bis an Kugelgriffe gezogen werden kann, um somit problemlos die Rakelmesser auszutauschen. Demzufolge wird in der Maschine wenig Platz benötigt, um den Rakelbalken handhaben zu können. Andererseits erfolgt das Festklemmen des Rakelbalkens in einer Halterung sowie das Anstellen des Rakelbalkens mit den Rakelblättern an eine Rasterwalze in einem Arbeitsgang durch Handhaben der Klemm- und Anstelleinrichtung.When using the invention, the following advantages occur in particular: when the chamber doctor blade or the doctor blade beam is removed from the holder, a guide is created by turning the tensioning levers horizontally, on which the squeegee bar can be pulled horizontally up to the ball handles, so that the doctor blades can be exchanged without any problems. As a result, little space is required in the machine to be able to handle the doctor bar. On the other hand, the squeegee bar is clamped in a holder and the squeegee bar is positioned with the squeegee blades on an anilox roller in one operation by handling the clamping and adjusting device.

Der ebenfalls nicht dargestellte Farbvorratsbehälter kann trichterförmig ausgeführt sein und gleichzeitig als Auffangbehälter für die abgerakelte Farbe dienen.The doctor bars 9 to 13 each have an ink supply nozzle 14, which is connected via a flexible line, not shown, to an ink pump, not shown, and an ink reservoir. The ink reservoir, also not shown, can be funnel-shaped and at the same time serve as a collecting container for the doctored paint.

Die Rakelbalken 9 und 11 werden von einer Halterung 16, und die Rakelbalken 12 und 13 werden von einer Halterung 17 aufgenommen. Die Halterungen 16; 17 sind auf einer Traverse 18 befestigt, die zwischen den Seitengestellen 7; 8 angeordnet ist. Jede Halterung 16; 17 weist vier Klemm- und Anstelleinrichtungen 19; 21 auf, die paarweise den Rakelbalken 9 bis 13 über jeweils Rakelbalkenhalterungen 22; 23 zugeordnet sind. An Stelle einer Rasterwalze kann auch eine andere farbabgebende Walze eingesetzt werden.The doctor bars 9 and 11 are received by a holder 16, and the doctor bars 12 and 13 are received by a holder 17. The brackets 16; 17 are fastened on a cross member 18 which is between the side frames 7; 8 is arranged. Each bracket 16; 17 has four clamping and adjusting devices 19; 21 on, the pairs of doctor bars 9 to 13 via doctor blade holders 22; 23 are assigned. Instead of an anilox roller, another ink-releasing roller can also be used.

Gemäß Fig. 2 bis 6 besteht die Klemm- und Anstelleinrichtung 19; 21 jeweils aus einem Körper 24, der zwei abgewinkelte, gabelförmige Enden 26; 27 aufweist.2 to 6 there is the clamping and adjusting device 19; 21 each from a body 24 which has two angled, fork-shaped ends 26; 27 has.

Zwischen den Enden 26; 27 ist eine Welle 28 angeordnet, die einen Hebel 29 trägt, der an seinem einen Ende einen Kugelgriff 31 und an seinem anderen Ende einen Exzenter 32 aufweist. Der Hebel 29 ist durch eine Bohrung im Exzenter 32 schwenkbar gelagert.Between the ends 26; 27, a shaft 28 is arranged which carries a lever 29 which has a ball handle 31 at one end and an eccentric 32 at its other end. The lever 29 is pivotally mounted through a bore in the eccentric 32.

Der Körper 24 ist in einer in axialer Richtung der Rakelbalkenhalterung 22; 23 verlaufenden Paßschraube 33 in einer Gewindelochbohrung 34 drehbar gelagert. Die Paßschraube 33 ist von einer Hülse 36 umgeben, deren Außendurchmesser dem Innendurchmesser der Sacklochbohrung 34 entspricht. Die Hülse 36 weist eine an ihrem Umfang verlaufende Ringnut 37 auf, in welche das Ende einer Klemmschraube 38 eingreift.The body 24 is in an axial direction of the doctor blade holder 22; 23 extending fitting screw 33 rotatably mounted in a threaded hole 34. The fitting screw 33 is surrounded by a sleeve 36, the outside diameter of which corresponds to the inside diameter of the blind hole 34. The sleeve 36 has an annular groove 37 running on its circumference, into which the end of a clamping screw 38 engages.

Zwischen dem Kopf 39 der paßschraube 33 und der Stirnseite der Hülse 36 sind Tellerfedern 41 angeordnet. Der Körper 24 weist noch eine in axialer Richtung der Paßschraube 33 verlaufende Führungsschiene 42 auf.Between the head 39 of the fitting screw 33 and the end face of the sleeve 36, plate springs 41 are arranged. The body 24 also has a guide rail 42 running in the axial direction of the fitting screw 33.

Die Rakelbalkenhalterungen 22; 23 besitzen außerdem noch jeweils eine in axialer Richtung der Rakelbalkenhalterungen 22; 23 verlaufende Fläche 43, die jeweils zwei sich quer zur axialen Richtung der Rakelbalkenhalterungen 22; 23 erstreckende Hebeleisten 44; 46 aufweist. Die Hebeleisten 44; 46 besitzen einen keilförmigen Querschnitt und weisen bei gleicher Höhe eine unterschiedliche Breite b 44; b 46 auf, d. h. sie besitzen eine unterschiedliche Steigung S 44; S 46. Dabei gilt: S 44 > S 46.The doctor blade holders 22; 23 also each have one in the axial direction of the squeegee supports 22; 23 extending surface 43, each two transverse to the axial direction of the Doctor bar supports 22; 23 extending lever strips 44; 46 has. The lever strips 44; 46 have a wedge-shaped cross section and have a different width b 44 at the same height; b 46 on, ie they have a different slope S 44; S 46. The following applies: S 44> S 46.

Der Rakelbalken 9 bis 13 besteht jeweils aus einem zweiteiligen Grundkörper 47; 48, der jeweils in einer Rakelhalterung 49; 51 eine Arbeitsrakel 52 bzw. eine Schließrakel 53 aufnimmt. Ein Schließblech 54, jeweils an der Stirnseite der Rakelbalken 9 bis 13 angeordnet, schließt die Kammerrakel zu einem oben offenen Behälter, der an die sich in Pfeilrichtung D bewegende Rasterwalze 1 anstellbar ist. Die Arbeitsrakel 52 wird im Winkel α zur Senkrechten 56 an die Rasterwalze 1 angestellt.The doctor bar 9 to 13 each consists of a two-part base body 47; 48, each in a doctor blade holder 49; 51 receives a working squeegee 52 or a closing squeegee 53. A striking plate 54, each arranged on the end face of the squeegee bars 9 to 13, closes the chambered squeegee to form an open-topped container which can be adjusted to the anilox roller 1 moving in the direction of arrow D. The working squeegee 52 is placed on the anilox roller 1 at an angle α to the vertical 56.

Der zweiteilige Grundkörper 47; 48 der Rakelbalken 9 bis 13 besitzt an seiner Unterseite jeweils Gegenleisten 50; 55 mit Kanten 57; 58, die im Falle der Bewegung des Rakelbalkens in Pfeilrichtung C mit den Hebeleisten 44; 46 in Wirkverbindung kommen. Der Grundkörper 48 besitzt eine Schaltmulde in Form eines Sackloches 59 mit einer einseitig in Richtung Kante 58 verlaufenden Senkung oder Abschrägung 61.The two-part base body 47; 48 of the doctor bars 9 to 13 each have counter strips 50 on their underside; 55 with edges 57; 58, which in the case of movement of the squeegee in the direction of arrow C with the lever bars 44; 46 come into active connection. The base body 48 has a switching recess in the form of a blind hole 59 with a depression or bevel 61 running on one side in the direction of the edge 58.

In gleicher Höhe und Lage der eben genannten Teile 59; 61 ist in einer Bohrung der Rakelbalken 23 ein gegen die Kraft einer Feder 62 in axialer Richtung der Rakelbalkenhalterung 23 betätigbares Druckstück 63 angeordnet. Dieses Druckstück 63 bekommt bei Betätigung des Rakelbalkens gemäß Fig. 2 in Pfeilrichtung C Kontakt mit einem Endschalter 64, der über Kontaktfahnen 66 und Anschlußkabel 67 mit einer nicht dargestellten, elektrischen Steuerung in Verbindung steht, welche die Farbpumpe anschaltet, wenn das Druckstück 63 in der Stellung nach Fig. 4 steht.At the same height and position of the parts 59; 61 is in a bore of the doctor bar 23 against the force of a spring 62 in the axial direction Doctor bar holder 23 operable pressure piece 63 is arranged. This pressure piece 63 gets actuation of the doctor bar according to FIG. 2 in the direction of arrow C contact with a limit switch 64, which is connected via contact lugs 66 and connecting cable 67 to an electrical control, not shown, which switches the ink pump on when the pressure piece 63 is in the 4 is in the position.

Gemäß Fig. 4 ist der Abstand e das Maß der Vorspannung der Tellerfedern 41, mit welchen die Rakelbalken 9 bis 13 eingespannt sind.4, the distance e is the measure of the pretension of the plate springs 41 with which the doctor bars 9 to 13 are clamped.

Soll nun der gezeigte Rakelbalken 9 aus der Arbeitsstellung gemäß den Fig. 1 und 4 entfernt werden, so sind die Hebel 29 mit den Kugelgriffen 31 in vertikaler Richtung nach unten zu bewegen, so daß diese die Stellung nach Fig. 6 oder Fig. 3 einnehmen. Dadurch hat der Exzenter 32 der Klemm- und Einstelleinrichtung 21 seine Spannwirkung gegen die Kraft der Tellerfedern 41 verloren, und gemäß Fig. 3 ist zwischen der Rakelbalkenhalterung 23 und dem Rakelbalken ein Abstand a eingetreten, in dem die Kanten 57; 58 die Hebeleisten 44; 46 verlassen haben und sich wieder auf der Fläche 43 der Rakelbalkenhalterungen 22; 23 befinden. Somit ist das Druckstück 63 nicht in Eingriff mit der Schaltmulde 59, so daß der Endschalter 64 die Farbzufuhr abgeschaltet hat.If the doctor bar 9 shown is now to be removed from the working position according to FIGS. 1 and 4, the levers 29 with the ball handles 31 are to be moved downwards in the vertical direction so that they assume the position according to FIG. 6 or 3 . As a result, the eccentric 32 of the clamping and adjusting device 21 has lost its tensioning action against the force of the plate springs 41, and according to FIG. 3, a distance a has occurred between the doctor bar holder 23 and the doctor bar in which the edges 57; 58 the lever strips 44; 46 have left and again on the surface 43 of the squeegee supports 22; 23 are located. Thus, the pressure piece 63 is not in engagement with the switching recess 59, so that the limit switch 64 has switched off the ink supply.

Soll nun der Rakelbalken in eine Montagestellung nach Fig. 5 gebracht werden, um beispielsweise die Rakel 52 oder 53 auszuwechseln, so werden die Hebel 29 mit den Kugelgriffen 31 seitlich nach außen verschwenkt, siehe auch Stellung des Rakelbalkens 13 in Fig. 1, so daß der Rakelbalken 13 auf den beiden Führungsschienen 42 herausgefahren werden kann, bis dieser gegen die Kugelgriffe 31 anschlägt.5, for example to replace the squeegee 52 or 53, the levers 29 are pivoted laterally outwards with the ball handles 31, see also position of the doctor bar 13 in Fig. 1, so that the doctor bar 13 can be moved out on the two guide rails 42 until it strikes the ball handles 31.

Somit ist nur ein geringer Platzbedarf notwendig, um die Rakelbalken 9 bis 13 gut handhaben zu können.Thus, only a small space is required in order to be able to handle the doctor bars 9 to 13 well.

Soll der Rakelbalken wieder in Ruhestellung oder in Arbeitsstellung gebracht werden, so ist umgekehrt zu verfahren.If the squeegee is to be returned to the rest position or the working position, the procedure is reversed.

Es ist auch möglich, das Spannen des Rakelbalkens durch andere technische Mittel als Tellerfedern und Exzenter vorzunehmen, beispielsweise durch pneumatische Arbeitszylinder. Der Körper 24 wird in seiner Drehbewegung zur waagerechten Stellung des Hebels 29 durch einen Anschlag 68 begrenzt.It is also possible to tension the squeegee bar by other technical means than disc springs and eccentrics, for example by pneumatic working cylinders. The body 24 is limited in its rotational movement to the horizontal position of the lever 29 by a stop 68.

Es ist auch möglich, gleiche Steigungen S44; S46 zu verwenden. Der Abstand f zwischen den Kanten 57; 58 der Gegenleisten 50; 55 nach Fig. 3 ist größer als der Abstand g zwischen den Hebeleisten 44; 46. Nach Fig. 4 stehen die Oberseiten 69; 70 der Hebeleisten 44; 46 in Wirkverbindung mit den ebenen Oberflächen der Gegenleisten 50; 55. Die Arbeitsrakel 52 ist nach Fig. 2 und 4 gegen die Kraft einer Feder 71 zurückschiebbar. Das Zurückschieben der Arbeitsrakel 52 ist beim Anstellvorgang der Arbeitsrakel an die Rasterwalze von Bedeutung, da die Arbeitsrakel 52 auf Grund der verschiedenen Steigungen S44; S46 der Hebeleisten 44; 46 eine Bewegung in Pfeilrichtung C nach Fig. 2 vollführt. Ein Nachschieben der Arbeitsrakel 52 erfolgt entsprechend dem Rakelverschleiß durch die Kraft der Feder 71.It is also possible to use the same gradients S44; Use S46. The distance f between the edges 57; 58 of the counter strips 50; 3 is greater than the distance g between the lever strips 44; 46. According to FIG. 4, the upper sides 69; 70 of the lever bars 44; 46 in operative connection with the flat surfaces of the counter strips 50; 55. The working doctor blade 52 can be pushed back against the force of a spring 71 according to FIGS. 2 and 4. The pushing back of the working squeegee 52 is important in the process of setting the working squeegee against the anilox roller, since the working squeegee 52 due to the different gradients S44; S46 of the lifting bars 44; 46 performs a movement in the direction of arrow C according to FIG. 2. The working squeegee 52 is pushed in according to the squeegee wear by the force of the spring 71.
