Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben.An embodiment of the invention is shown in the drawing and will be described in more detail below.
Es zeigen:Show it:
Fig. 1 eine Vorrichtung im Querschnitt in Plattenhalte- oder Ruhestellung; Fig. 2 eine Vorrichtung nach Fig. 1 in Plattenaufnahme- oder Arbeitsstellung; Fig. 3 einen Schnitt IM - III nach Fig. 1 in einer Teildarstellung in verkleinerten Maßstab und in einer weiteren Ausführungsvariante.Figure 1 shows a device in cross section in the plate holding or rest position. FIG. 2 shows a device according to FIG. 1 in the plate receiving or working position; Fig. 3 shows a section IM - III of FIG. 1 in a partial representation on a reduced scale and in a further embodiment.
Ein Zylinder 01 , z. B. ein Platten- oder Gummituchzylinder einer Rotationsdruckmaschine ist zur Aufnahme von biegsamen Platten 02 mit mindestens einer in Achsrichtung verlaufenden Zylindergrube 03 versehen. Die Zylindergrube 03 trägt an einer in Produktionsrichtung A des Zylinders 01 weisenden vorderen Kante 04 einen vorderen oder "vorauslaufenden" Einhängeschenkel 06 der Platte 02. Die Platte 02 weist noch einen hinteren oder "nachlaufenden" Einhängeschenkel 07 auf, welcher an einer zweiten hinteren Kante 08 der gleichen Zylindergrube 03 eingehangen ist.A cylinder 01, e.g. B. a plate or blanket cylinder of a rotary printing press is provided for receiving flexible plates 02 with at least one axial pit 03 extending in the axial direction. The cylinder pit 03 carries a front or "leading" hanging leg 06 of the plate 02 on a front edge 04 pointing in the production direction A of the cylinder 01. The plate 02 also has a rear or "trailing" hanging leg 07, which on a second rear edge 08 the same cylinder pit 03 is attached.
Am Umfang des Zylinders 01 können auch zwei Platten, z. B. Druckplatten angeordnet sein. Dann werden in Umfangsrichtung des Zylinders 01 zwei Zylindergruben benötigt. Ein zwischen der Mantelfläche 11 des Zylinders 01 und der ersten Grubenwand 12 der Zylindergrube 03 ist ein spitzer Öffnungswinkel Alpha gebildet, z. B. bis 45°. Die zweite, etwa in radialer Richtung des Zylinders 01 verlaufende Grubenwand 13 weist einen stumpfen Öffnungswinkel Beta von etwa 95° zur Mantelfläche 11 auf. Beide Kanten 04; 08 oder auch Scheitelpunkte der Öffnungswinkel Alpha; Beta sind durch einen Befestigungsschlitz 09 getrennt.On the circumference of the cylinder 01 two plates, for. B. pressure plates may be arranged. Then two cylinder pits are required in the circumferential direction of the cylinder 01. An acute opening angle Alpha is formed between the lateral surface 11 of the cylinder 01 and the first pit wall 12 of the cylinder pit 03, z. B. up to 45 °. The second pit wall 13, which runs approximately in the radial direction of the cylinder 01, has an obtuse opening angle Beta of approximately 95 ° to the lateral surface 11. Both edges 04; 08 or vertices of the opening angle alpha; Beta are separated by a fastening slot 09.
Der Befestigungsschlitz 09 ist in seiner lichten Weite b so ausgebildet, daß nebeneinander zumindest zwei Einhängeschenkel 06; 07 darin Platz finden, welche in Richtung Zylindergrube 03 ragen.The mounting slot 09 is formed in its internal width b so that at least two hanging legs 06; 07 find space in it, which protrude towards the cylinder pit 03.
Es ist möglich, anstatt einer Druckplatte oder mehrerer nebeneinander liegenden Druckplatten auch biegsame Trägerplatten mit darauf angeordneten Gummitüchern zu befestigen.Instead of a printing plate or several printing plates lying next to one another, it is also possible to fasten flexible carrier plates with rubber blankets arranged on them.
Die Zylindergrube 03 kann im Querschnitt etwa kreisförmig ausgebildet sein und ist durch den Befestigungsschlitz 09 mit der Mantelfläche 11 verbunden.The cylinder pit 03 can be approximately circular in cross section and is connected to the lateral surface 11 by the fastening slot 09.
In der Zylindergrube 03 ist eine um ihre Längsachse verschwenkbare, sich mit ihrer Längsachse in axialer Richtung der Zylindergrube 03 erstreckende dreiarmige Profilleiste 14 angeordnet. Die Arme 16; 17; 18 erstrecken sich ebenfalls leistenförmig in achsparalleler Richtung.Arranged in the cylinder pit 03 is a three-armed profile bar 14 which can be pivoted about its longitudinal axis and extends with its longitudinal axis in the axial direction of the cylinder pit 03. The arms 16; 17; 18 also extend in the form of strips in the direction parallel to the axis.
Ein erster Arm 16 oder Kraftarm weist im Querschnitt gesehen (Fig. 1) in etwa in radialer, der Platte 02 abgewandten Richtung. Ein zweiter Arm 17 oder Lastarm weist in etwa in radialer, jedoch der Platte 02 zugewandten Richtung. Der zweite Arm 17 ist mit seinem freien Ende 19 gegen den an der zweiten Grubenwand 13 anliegenden zweiten Einhängeschenkel 07 andrückbar angeordnet. Zwischen dem ersten 16 und zweiten Arm 17 ist der dritte Arm 18 oder Lagerarm angeordnet, welcher an seinem freien Ende 21 leicht abgewinkelt ist und einen Wulst 22 trägt. Dieser Wulst 22 ist in einer sich in achsparalleler Richtung erstreckenden Rinne 23 einer zylindergrubenfesten Stützleiste 24 schwenkbar gelagert, d. h. Wulst 22 und Rinne 23 bilden ein Lager.A first arm 16 or power arm, viewed in cross section (FIG. 1), points approximately in the radial direction facing away from the plate 02. A second arm 17 or load arm points approximately in the radial direction, however, facing plate 02. The free end 19 of the second arm 17 is arranged such that it can be pressed against the second hanging leg 07 resting against the second pit wall 13. Between the first 16 and second arm 17, the third arm 18 or bearing arm is arranged, which is slightly angled at its free end 21 and carries a bead 22. This bead 22 is pivotally mounted in a groove 23 of a support strip 24 which is fixed in the axially parallel direction, that is to say a bead 22 and groove 23 form a bearing.
Zwischen einer in Richtung Befestigungsschlitz 09 weisenden ersten Stützfläche 26 des dritten Armes 18 und einer im Winkel Gamma 1 von ca. 30° bis 60°, insbesondere von ca. 45° dazu angeordneten stützleistenfesten zweiten Stützfläche 27 ist ein keilförmiger Schlitz 28 gebildet. Durch Verschwenken der Profilleiste 14 ist der Keilwinkel Gamma 1 in Keilwinkel Gamma 2 (ca. 50°) änderbar.A wedge-shaped slot 28 is formed between a first support surface 26 of the third arm 18 pointing in the direction of the fastening slot 09 and a second support surface 27 fixed to the support strip and arranged at an angle gamma 1 of approximately 30 ° to 60 °, in particular approximately 45 °. The wedge angle gamma 1 can be changed into wedge angle gamma 2 (approx. 50 °) by pivoting the profile strip 14.
Die auf dem dritten Arm 18 befindliche erste Stützfläche 26 kann z. B. dadurch gebildet werden, daß der zweite Arm 17 eine Aussparung 29 erhält.The first support surface 26 located on the third arm 18 can e.g. B. be formed in that the second arm 17 receives a recess 29.
Der keilförmige, keilwinkelveränderbare Schlitz 28 nimmt eine Klemmrolle 31 auf. Je nach Betrag der Keilwinkel Gamma 1 ; Gamma 2 liegt die Klemmrolle 31 in Plattenhaltestellung (Fig. 1) an dem vorderen Einhängeschenkel 06 an und drückt diesen an die erste Grubenwand 12 oder entfernt sich von der Grubenwand 12 in einer zweiten Plattenentnahmestellung (Fig. 2).The wedge-shaped, wedge angle variable slot 28 receives a pinch roller 31. Depending on the amount of the wedge angle gamma 1; Gamma 2, the pinch roller 31 lies in the plate holding position (FIG. 1) on the front hanging leg 06 and presses it against the first pit wall 12 or moves away from the pit wall 12 in a second plate removal position (FIG. 2).
Um eine erforderliche Schwenkbewegung der Profilleiste 14 zu erzeugen, ist zwischen dem ersten Arm 16 der Profilleiste 14 und der Wand 32 der Zylindergrube 03 ein Stellmittel, z. B. ein mit einem mit Druckluft befüllbaren Schlauch, Luftschlauch 33 genannt, angeordnet. Der Luftschlauch 33 ist an einem seiner Enden z. B. mit einem Ventil versehen und wird über eine damit verbundenen, nicht dargestellten Leitung zum Zylinderzapfen und mittels einer bekannten Dreheinführung im Bedarfsfalle mit Druckluft beaufschlagt.In order to generate a required pivoting movement of the profile bar 14, an adjusting means, for. B. arranged with a fillable with compressed air hose, called air hose 33. The air hose 33 is z. B. is provided with a valve and is pressurized via an associated line, not shown, to the cylinder journal and by means of a known rotary introduction if necessary with compressed air.
Zwischen Profilleiste 14 und Stützleiste 24 sind eine oder mehrere Federn 34; z. B. Druckfedern, angeordnet, deren Enden sich einerseits an der Stützleiste 24 und andererseits in Sacklochbohrungen 35 der luftschlauchfernen Seite des ersten Armes 16 der schwenkbaren Profilleiste 14 abstützen.Between profile bar 14 and support bar 24 are one or more springs 34; z. B. compression springs, the ends of which are on the one hand on the support bar 24 and on the other hand, support in blind holes 35 on the side of the first arm 16 of the pivotable profile strip 14 remote from the air hose.
Soll nun die Vorrichtung von der Plattenhalte- oder Ruhestellung (Fig. 1) in die Plattenentnahme- oder Arbeitsstellung (Fig. 2) gebracht werden, so wird der Luftschlauch 33 mit Druckluft beaufschlagt. Dabei liegt eine Widerlagerfläche 36 des Luftschlauches 33 an der Wand 32 der Zylindergrube 03 und eine Kraftangriffsfläche 37 des Luftschlauches 33 am ersten Arm 16 der Profilleiste 14 an. Dadurch erfolgt eine Schwenkbewegung der Profilleiste 14 um das Lager 22; 23, so daß das freie Ende 19 mit dem hinteren Einhängeschenkel 07 und der zweiten Grubenwand 13 außer Eingriff kommt. Weiterhin vergrößert sich der Keilwinkel von Gamma 1 auf Gamma 2 , so daß die Klemmrolle 31 in Richtung Scheitelpunkt des Keilwinkels Gamma 2 rollt (Fig. 2). Dadurch kommt der Umfang der Klemmrolle 31 mit dem vorderen Einhängeschenkel 06 außer Eingriff, welcher bisher an die Grubenwand 12 gedrückt wurde. Die Platte 02 kann entnommen bzw. gewechselt werden. Nach einem Entlüften des Luftschlauches 33 kommen die Teile 19; 31 wieder in Wirkverbindung mit den Einhängeschenkeln 06; 07.If the device is now to be brought from the plate holding or rest position (FIG. 1) into the plate removal or working position (FIG. 2), the air hose 33 is pressurized with compressed air. Here, an abutment surface 36 of the air hose 33 bears against the wall 32 of the cylinder pit 03 and a force application surface 37 of the air hose 33 bears against the first arm 16 of the profile strip 14. This results in a pivoting movement of the profile bar 14 about the bearing 22; 23 so that the free end 19 comes out of engagement with the rear suspension leg 07 and the second pit wall 13. Furthermore, the wedge angle increases from gamma 1 to gamma 2, so that the pinch roller 31 rolls in the direction of the apex of the wedge angle gamma 2 (FIG. 2). As a result, the circumference of the pinch roller 31 disengages from the front suspension leg 06, which was previously pressed against the pit wall 12. The plate 02 can be removed or replaced. After venting the air hose 33, the parts 19; 31 again in operative connection with the hanging legs 06; 07th
Nach einer in Fig. 3 gezeigten Ausführungsvariante ist die Profilleiste 14 in achsparalleler Richtung in mehrere kürzere Profilleisten 38; 39; 40 unterteilt. Das Gleiche gilt auch für die Stützleiste 24 welche in mehrere Stützleisten 42; 43; 44 unterteilt ist. Jede Stützleiste 42; 43; 44 ist gegenüber der benachbarten Stützleiste lösbar, z. B. mittels einer Kupplung verbunden. Diese Kupplung kann z. B. formschlüssig wirken und mittels einer beidendigen Verzahnung 46; 47 der Stützleisten 42; 43; 44 realisiert werden. Der Luftschlauch 33 ist immer einstückig ausgebildet und durchläuft die gesamte Zylindergrube 03. Ein freies Ende der sich in der Zylindergrube 03 befindlichen ersten und letzten Stützleiste ist drehfest mit einem Endkuppelstück 48 verbunden. Das Endkuppelstück 48 ist mit seinen die Zylindergrube 03 überdeckenden Teilen an den Flanken des Zylinders 01 befestigt, z. B. verschraubt. Durch die Verwendung von mehreren kurzen Profilleisten 38 bis 40 kann die Vorrichtung z. B. zu Wartungszwecken aus der Zylindergrube 03 entnommen werden, ohne daß dabei der Zylinder 01 aus dem Seitengestell demontiert werden muß. According to an embodiment variant shown in FIG. 3, the profile strip 14 is in the axis-parallel direction in several shorter profile strips 38; 39; 40 divided. The same also applies to the support strip 24 which is divided into a plurality of support strips 42; 43; 44 is divided. Each support bar 42; 43; 44 is releasable relative to the adjacent support bar, for. B. connected by means of a clutch. This clutch can e.g. B. act positively and by means of a double-sided toothing 46; 47 of the support strips 42; 43; 44 can be realized. The air hose 33 is always made in one piece and runs through the entire cylinder pit 03. A free end of the first and last support strip located in the cylinder pit 03 is connected in a rotationally fixed manner to an end coupling piece 48. The end coupling piece 48 is fastened with its parts covering the cylinder pit 03 to the flanks of the cylinder 01, for. B. screwed. By using several short profile strips 38 to 40, the device can, for. B. can be removed from the cylinder pit 03 for maintenance purposes without the cylinder 01 having to be removed from the side frame.
