Abstract

1. Gripper mechanism on cylinders for printing machines, particularly rotary sheet printing machines for recto and verstoprinting, wherein the gripper mechanism consists of cam-controlled grippers (13) rotatably arranged on a gripper shaft (11) and a gripper base (12) and is arranged rotatably in a cylinder channel (2) within the shape of the cylinder in such a way that a rubber blanket (16) necessary for the printing can be inserted and tensioned between the gripper base and the cylinder channel wall (15), characterized in that the gripper shaft (11) is mounted eccentrically in mouting bushes (10) which in turn are mounted in the side walls of the cylinder channel (2), that the gripper base (12) mounted on the gripper shaft (11) is supported via a link (9) pivoted rotatably to the floor of the cylinder channel (7) at (8), so that thereby on rotating the bearing bushes (10) the gripper shaft (11) with the grippers (13) and gripper base (12) can be moved away from the cylinder channel wall (15), wherein the dimensioning of the eccentricity an the link connecion between gripper shaft (11), gripper base (12), link (9) and link pivot point (8) is so determined that gripper and gripper base are movable approximately in the cylinder peripheral direction.

Description

Die Erfindung betrifft eine Greifereinrichtung an Zylindern für Druckmaschinen, insbesondere Bogenrotationsdruckmaschinen für Schön- und Widerdruck, wobei die Greifereinrichtung aus auf einer Greiferwelle verdrehbar angeordneten, kurvengesteuerten Greifern und aus Greiferauflagen besteht und in einem Zylinderkanal derart schwenkbar angeordnet ist, daß zwischen Greiferauflage und Zylinderkanalwand ein für den Druck erforderliches Gummituch einfüg- und spannbar ist.The invention relates to a gripper device on cylinders for printing presses, in particular sheet-fed rotary printing presses for perfecting, where the gripper device consists of cam-controlled grippers rotatably arranged on a gripper shaft and of gripper supports and is pivotably arranged in a cylinder channel in such a way that one between the gripper support and the cylinder channel wall the pressure required blanket can be inserted and stretched.

Es ist bekannt, daß bei Rollenrotationsoffsetdruckmaschinen ein sogenanntes Gummi-Gummi-Druckwerk verwendet wird, d.h. der Druck erfolgt zwischen zwei mit Gummitüchern bespannten Zylindern.It is known that a so-called rubber-rubber printing unit is used in web-fed rotary offset printing machines, i.e. printing takes place between two cylinders covered with rubber blankets.

Wenn dieses Druckprinzip auf Bogenmaschinen übertragen werden soll, so muß an mindestens einem Gummizylinder eine Greifereinrichtung zum Festhalten und Transport der Bogen vorgesehen sein. Diese Greifereinrichtung muß so angeordnet sein, daß möglichst nahe am Druckanfang der Bogen gehalten ist. Weiterhin muß die Möglichkeit bestehen, das Gummituch auf dem Zylinder zu befestigen und zu spannen. Diese Forde- rung erfordert eine besondere Ausgestaltung der Greifereinrichtung, nämlich der, daß die Greifereinrichtung abschwenkbar ausgebildet sein muß.If this printing principle is to be transferred to sheet-fed machines, a gripper device for holding and transporting the sheets must be provided on at least one rubber cylinder. This gripper device must be arranged so that the sheet is held as close as possible to the start of printing. It must also be possible to attach and stretch the rubber blanket on the cylinder. This requirement requires a special design of the gripper device, namely that the gripper device must be designed to be pivotable.

Eine derartige Vorrichtung zeigt z.B. die DE-OS 1 561 082, bei der Greifer und Greiferauflage auf einem Hebel angeordnet sind, der schwenkbar über einen Kurbeltrieb antreibbar ist. Im abgeschwenkten Zustand gibt der Hebel eine Befestigungseinrichtung freiin die das Gummituch eingeführt werden kann. Da der Hebel gleichzeitig als Greiferauflage und Lager für die Greiferwelle Anwendung findet und der Antrieb des Hebels über eine angefederte Koppel erfolgt, birgt diese Ausgestaltung einen Nachteil, nämlich den, daß keine feste Verbindung zwischen Antrieb und Hebel vorgesehen ist und somit Fehler auftreten können.Such a device is shown, for example, in DE-OS 1 561 082, in which the gripper and gripper support are arranged on a lever which can be pivotally driven via a crank mechanism. In the pivoted state, the lever releases a fastening device into which the rubber blanket can be inserted. Since the lever acts as a gripper pad and Bearings for the gripper shaft is used and the lever is driven via a spring-loaded coupling, this configuration harbors a disadvantage, namely that no fixed connection is provided between the drive and the lever and errors can therefore occur.

Die Aufgabe der Erfindung besteht deshalb darin, einen abschwenkbaren Greifer für einen Druckzylinder so auszugestalten, daß beim Abschwenken des Greifers bei einer vorgegebenen Greifersteuerkurve der Greifer geschlossen bleibt und damit keine Relativbewegung zwischen Greiferspitze und Greiferauflage eintritt. Weiterhin soll bei abgeschwenktem Greifer eine Sicherung aktiv werden, die einen Vorwärtslauf der Maschine verhindert und nur einen Schleichgang zuläßt.The object of the invention is therefore to design a swiveling gripper for a pressure cylinder in such a way that when the gripper is swiveled out, the gripper remains closed for a given gripper control curve and thus no relative movement between the gripper tip and the gripper support occurs. Furthermore, when the gripper is swiveled away, a safety device should be activated which prevents the machine from running forwards and only allows a creep speed.

Gelöst wird diese Aufgabe durch das Kennzeichen des ersten Patentanspruchs.This problem is solved by the characteristic of the first claim.

Der Vorteil dieser Vorrichtung liegt darin, daß beim Abschwenken des Greifers dieser geschlossen bleibt und auch keine Relativbewegung zur Greiferauflage ausführt. Weiterhin ist es vorteilhaft, daß der Greifer nach dem Abschwenken innerhalb des Zylinderumfangs bleibt. Hierdurch wird eine Beschädigung der Greifer und des Gummituches verhindert. Durch die Anordnung der Greiferwelle in einem verschwenkbaren Exzenter wird auf einfachste Art das Schwenken der Greifer ermöglicht. Durch die günstige Ausgestaltung des Schwenkgetriebes wird eine annähernde Verschwenkung der Greifer in Zylinderumfangsrichtung ermöglicht, wodurch auch der Hebel für die Greiferöffnung lediglich der Greiferöffnungskurve folgend bewegt wird. Hierdurch ist gewährleistet, daß der Greifer beim Schwenken geschlossen bleibt. Bei der erfindungsgemäßen Anordnung ist auch gewährleistet, daß bei durch Kurven zu schließenden Greifern die oben beschriebenen Forderungen erfüllt sind.The advantage of this device is that when the gripper is swiveled it remains closed and does not perform any relative movement to the gripper support. It is also advantageous that the gripper remains within the cylinder circumference after pivoting. This prevents damage to the grippers and the rubber blanket. The arrangement of the gripper shaft in a pivotable eccentric enables the gripper to be pivoted in the simplest way. The favorable design of the swivel gear enables the grippers to be pivoted approximately in the cylinder circumferential direction, as a result of which the lever for the gripper opening is only moved following the gripper opening curve. This ensures that the gripper remains closed when swiveling. In the arrangement according to the invention it is also ensured that when closing by curves Grab the requirements described above are met.

Nachfolgend ist an einem Ausführungsbeispiel die Erfindung näher erläutert:

  • Fig. 1 zeigt einen Schnitt durch den mit Greifern bestückten Gummizylinder einer Schön- und Widerdruckmaschine.
  • Fig. 2 zeigt eine Aufsicht entsprechend der Fig. 1.
The invention is explained in more detail below using an exemplary embodiment:
  • Fig. 1 shows a section through the rubber cylinder equipped with grippers of a perfecting machine.
  • FIG. 2 shows a top view corresponding to FIG. 1.

Der Zylinder 1 weist in einem Kanal 2 zwei Spannwellen 3+4 auf, die Ausnehmungen 5 zur Aufnahme von armierten Gummituchenden 6 besitzen. Auf dem Boden 7 des Kanals ist ein Lager befestigt, an dem eine Lasche 9 beweglich angelenkt ist. In den den Kanal 2 seitlich begrenzenden, nicht gezeigten Seitenwänden, ist eine Exzenterbüchse 10 gelagert, an der die Lasche 9 ebenfalls beweglich angelenkt ist. In der Exzenterbüchse 10 ist die Greiferwelle 11 gelagert. Desweiteren ist die Greiferauflage 12 auf der Greiferwelle 11 gelagert und gelenkig an der Lasche 9 angelenkt. Druch diese Dreigelenkkette 8, 9, 12 ergibt sich für die Greiferauflage 12 eine stabile Lage. Während der gezeigten Arbeitsstellung befinden sich die Greiferauflage 12 und die Greifer 13 in einer solchen Position, in der ein geringer Abstand zur Druckanfangskante 14 besteht. Zwischen der Greiferauflage 12 und der Wand 15 des Zylinderkanals 2 befindet sich das Gummituch 16. Zum Befestigen des Gummituches 16 ist es erforderlich, den Greifer 13 mit der Greiferauflage 12 abzuschwenken. Hierzu wird die exzentrische Lagerbüchse 10um ca. 45° verschwenkt, wodurch die Greiferauflage 12 mit dem Greifer 11 zusammen abgeschwenkt wird. Zum Verschwenken weist die Lagerbüchse 10 einen Ansatz mit einer Bohrung 19 auf in die ein herausnehmbaren Hebel einsteckbar ist. Mit diesem Hebel ist die Lagerbüchse 10 mit den Greifern und Greiferauflagen wegschwenkbar. Durch die geometrische Ausgestaltung der Exzenterbüchse 10 ergibt sich für den Greifer 13 und die Greiferauflage 12 eine annähernd geradlinige Bewegung, so daß der Greifer 13 nicht öffnet.The cylinder 1 has two tension shafts 3 + 4 in a channel 2, which have recesses 5 for receiving reinforced rubber blanket ends 6. On the bottom 7 of the channel, a bearing is attached, on which a tab 9 is articulated. In the side walls, not shown, which laterally delimit the channel 2, an eccentric bushing 10 is mounted, on which the tab 9 is also articulated. The gripper shaft 11 is mounted in the eccentric bushing 10. Furthermore, the gripper pad 12 is mounted on the gripper shaft 11 and articulated on the tab 9. This three-link chain 8, 9, 12 results in a stable position for the gripper pad 12. During the working position shown, the gripper pad 12 and the grippers 13 are in a position in which there is a small distance from the printing start edge 14. The rubber blanket 16 is located between the gripper pad 12 and the wall 15 of the cylinder channel 2. To fasten the rubber blanket 16, it is necessary to pivot the gripper 13 with the gripper pad 12 away. For this, the eccentric Bearing bush 10 is pivoted about 45 °, whereby the gripper pad 12 is pivoted together with the gripper 11. For pivoting, the bearing bush 10 has a shoulder with a bore 19 into which a removable lever can be inserted. With this lever, the bearing bush 10 can be pivoted away with the grippers and gripper pads. The geometric configuration of the eccentric bushing 10 results in an approximately rectilinear movement for the gripper 13 and the gripper support 12, so that the gripper 13 does not open.

Damit bei abgeschwenktem Greifer 13 und damit beim Aufziehen des Gummituches 16 der Bedienungsmann keiner Verletzungsgefahr ausgesetzt ist, wird durch eine bekannte Schutzschaltung der Maschinenantrieb so geschaltet, daß lediglich ein Schleichgang im Rückwärtsbetrieb ermöglicht wird. Die Schutzschaltung wird über den Schwenkmechanimus des Greifers 13 betätigt. Durch eine mechan. Verriegelung 17 ist der Greiferschwenkmechanismus zusätzlich in Arbeitsposition arretierbar.So that the operator is not exposed to any risk of injury when the gripper 13 is pivoted away and thus when the rubber blanket 16 is pulled up, the machine drive is switched by a known protective circuit so that only a creep speed is made possible in reverse operation. The protective circuit is actuated via the swivel mechanism of the gripper 13. By a mechan. Locking 17, the gripper swivel mechanism can also be locked in the working position.
