Description
Die Erfindung betrifft eine Saugersteuerung in Bogenübergabetrommeln in Mehrfarben-Bogenrotationsdruckmaschinen zum Wenden des Bogens nach dem Prinzip der Hinterkantenwendung beim Überführen der Bogen von einem Druckwerk zum anderen, um die Bogenrückseite zu bedrucken, nach dem Oberbegriff des ersten Patentanspruches.The invention relates to a suction control in sheet transfer drums in multi-color sheet-fed rotary printing presses for turning the sheet according to the principle of turning the trailing edge when transferring the sheet from one printing unit to another in order to print on the back of the sheet, according to the preamble of the first claim.
Eine Saugersteuerung gemäß Oberbegriff ist z.B. aus der DE-A-3829626 bekannt.Suction control according to the generic term is e.g. known from DE-A-3829626.
Aufgabe der Erfindung ist es, die Saugersteuerung der eingangs spezifizierten Gattung so zu verbessern, daß es möglich wird, Stöße bei der Übernahme des Bogens vom Druckzylinder und bei der Übergabe des Bogens an das erste Greifersystem zu verringern und zugleich den Antrieb des schwingenden Saugersystems in Bewegungsrichtung zu beeinflussen.The object of the invention is to improve the suction control of the type specified at the outset in such a way that it becomes possible to reduce shocks when the sheet is taken over from the impression cylinder and when the sheet is transferred to the first gripper system and at the same time drive the vibrating suction system in the direction of movement to influence.
Gelöst wird diese Aufgabe durch die im Kennzeichen des ersten Patentanspruches aufgeführten Merkmale.This object is achieved by the features listed in the characterizing part of the first claim.
Die Erfindung ermöglicht es, den Bogen mittels eines schwenkbaren Saugersystems exakt vom vorgeordneten Druckzylinder abzunehmen und exakt an das erste mechanische Greifersystem der Bogenübergabetrommel zu übergeben, wobei die Führungsrollen des schwenkbaren Saugersystems kraftschlüssig auf ihrer Steuerkurve gehalten werden.The invention makes it possible to remove the sheet exactly from the upstream printing cylinder by means of a pivotable suction system and to transfer it exactly to the first mechanical gripper system of the sheet transfer drum, the guide rollers of the pivotable suction system being held non-positively on their control curve.

Fig. 1 zeigt die Bogenübergabetrommel 18 und den dieser vorgeordneten Druckzylinder 17 während der Phase der Übernahme des Bogens mittels des schwenkbaren Saugersystems vom vorgeordneten Druckzylinder 17. Die Stellung der Sauger 3 des Saugersystems während der Übergabe an das erste Greifersystem 4 ist strichpunktiert eingezeichnet.Fig. 1 shows the
Das erste Greifersystem 4 übergibt in bekannter Weise an das zweite Greifersystem 5.The
Die Sauger 3 und der Steuerhebel 6 sind mit der hohlen Saugerschwingwelle 2 fest verbunden. Der Steuerhebel 6 weist zwei Führungsrollen 20.1 bzw. 20.2 auf, die auf einer Steuerkurve 7 abrollen, welche auf Führungsschienen 19 vorgesehen ist. Die Führungsschienen 19 sind fest mit einem Halter 8 verbunden, der am Trommelkörper 9 befestigt ist. Der Antrieb des Saugersystems erfolgt über eine Kurvenscheibe 13, die am Maschinenständer befestigt ist. Hierzu rollt die Kurvenrolle eines Rollenhebels 12 auf der Kurve der Kurvenscheibe 13 ab, der fest mit dem Ende der Antriebswelle 1 verbunden ist. Außerdem ist mit der Antriebswelle 1 ein Antriebshebel 11 fest verbunden, der über eine Lasche 10 mit einem Arm des Steuerhebels 6 gelenkig verbunden ist. Sowohl der Antriebshebel 11 als auch die Führungsschiene 19 mit Halter 8 sind zu beiden Seiten der Bogenübergabetrommel 18 und auch zwischen den Seiten am Trommelkörper 9 vorgesehen. Mit einer Feder 14 wird über den Antriebshebel 11 und die Antriebswelle 1 die Kurvenrolle des Rollenhebels 12 auf der Kurve der Kurvenscheibe 13 gehalten.The
Die Steuerkurve 7 weist Kurvenabschnitte mit einem Bewegungsgesetz auf, das es ermöglicht, die Saugerflächen der auf der hohlen Saugerschwingwelle 2 befestigten Sauger 3 des Saugersystems auf einer Bahn zu bewegen, die in der Fig. 3 als Einzelheit dargestellt ist. In einer ersten Phase erfassen die Sauger 3 die Hinterkante des Bogens auf der Peripherie des vorgeordneten Druckzylinders 17 und bewegen sich mit einer verlängerten Wegstrecke auf dieser Peripherie zunächst mit Druckzylindergeschwindigkeit. In einer zweiten Phase werden die Sauger 3 des Saugersystems noch vor dem Tangentenpunkt zwischen Bogenübergabetrommel 18 und Druckzylinder 17 unter die Peripherie der Bogenübergabetrommel 18 gesteuert, wobei der Bogen vom Druckzylinder 17 abgeschält wird, weil er straff gehalten von den Saugern 3 auf einer Evolventenbahn im bewegten Koordinatensystem geführt ist. Schließlich übergeben die Sauger 3 des Saugersystems in einer dritten Phase an das erste Greifersystem 4, ohne daß sich der Ablenkwinkel zwischen den Saugflächen der Sauger 3 und dem Bogen verändert, d.h. er bleibt annähernd gleich Null.The
Um Stöße bei der Übernahme des Bogens an seiner Hinterkante durch das vorstehend beschriebene schwenkbare Saugersystem auf den Druckzylinder 17 und bei der Übergabe des Bogens mittels des schwenkbaren Saugersystems an das erste Greifersystem 4 auszugleichen - wobei die Bewegung des Saugersystems bis an nicht dargestellte Anschläge am ersten Greifersystem 4 erfolgt, um die Lage der Bogenhinterkante für die Übergabe festzulegen - und zugleich den mittels der Kurvensteuerung 1, 10, 11, 12, 13 erfolgenden Antrieb des schwenkbaren Saugersystems in Bewegungsrichtung zu beeinflussen, sind an den Steuerhebeln 6 zwei auf die Achse der hohlen Saugerschwingwelle 2 von unten gerichtete, zueinander etwa rechtwinkelig angordnete Druckfedern 15, 16 angelenkt, die mit ihrem anderen Ende an der Bogenübergabetrommel 18 abgestützt sind (siehe Fig. 1 und Fig. 4 bis 7). Die Druckfedern 15, 16 unterstützen somit das Abrollen der Führungsrollen 20 auf der Steuerkurve 7 der Führungsschiene 19 und drücken zugleich die Führungsrollen 20 des Steuerhebels 6 gegen die Steuerkurve 7.To avoid shocks when taking over the sheet at its rear edge by the pivotable suction system described above on the
Gemäß Fig. 5 ist in der Phase der Übernahme des Bogens vom Druckzylinder 17 die Druckfeder 15 gespannt, während die Druckfeder 16 entspannt ist. Dadurch werden Stöße auf dem Druckzylinder durch das Saugersystem verhindert, zugleich unterstützt die Druckfeder 15 das Beschleunigen des Saugersystems in Bewegungsrichtung.5, the
Gemäß Fig. 6 sind etwa auf halbem Pendelweg des schwenkbaren Saugersystems beide Druckfedern 15, 16 gleich gespannt. Das bewegte Saugersystem befindet sich in einer Phase, in der eine Beschleunigungsumkehr erfolgt. In dieser Phase bewirken die Federkräfte der Druckfedern 15, 16 weder eine Beschleunigung noch eine Abbremsung.6, the two
Gemäß Fig 7 ist die Druckfeder 15 in der Phase der Übergabe des Bogens vom Saugersystem an das erste Greifersystem 4 entspannt, während die Druckfeder 16 gespannt ist. Auf diese Weise wird durch Abbremsen der Bewegung ein stoßfreies Anschlagen des Saugersystems an die nicht dargestellten Anschläge zur Lagefestlegung der Bogenhinterkante für die Übergabe an das erste Greifersystem 4 erreicht, in dem die Druckfeder 16 das Abbremsen des Saugersystems unterstützt. Auf dem Rückweg des Saugersystems von der Übergabestellung zur Übernahmestellung kehrt sich der abgefederte Bewegungsablauf entsprechend um.7, the
Die Druckfedern 15, 16 sind jeweils auf Federstangen geführt, die Federstützen aufweisen, die mit einem Ende am Steuerhebel 6 bzw. mit dem anderen Ende am Trommelkörper 9 angelenkt bzw. abgestützt sind.The
In der Zeichnung ist nicht dargestellt, daß der Bogen schließlich auf den Greiferauflagen des ersten Greifersystems 4 von dessen Greiferfingern geklemmt wird, wobei die Schwenkbewegung des Saugersystems wie bereits erwähnt bis zur Anlage an nicht dargestellte Anschläge am ersten Greifersystem 4 erfolgt, um die Bogenhinterkante in bekannter Weise in ihrer Lage festzulegen.In the drawing it is not shown that the sheet is finally clamped on the gripper supports of the
In ebenfalls bekannter Weise übergibt das erste Greifersystem 4 an ein in der Zeichnung nicht näher dargestelltes zweites Greifersystem 5 und von diesem an das Greifersystem des nachfolgenden nicht dargestellten Druckzylinders.
