Description

Die Erfindung betrifft Greifer für Bogenrotationsdruckmaschinen gemäß dem Oberbegriff des Patentanspruches 1.The invention relates to grippers for sheet-fed rotary printing machines according to the preamble of patent claim 1.

Gemäß EP 02 13 397 sind Greifer für Bogenrotationsdruckmaschinen bekanntgeworden, wobei die Greiferfinger auf metallischen Federelementen befestigt sind, um den Bogen gegen eine Greiferauflage federnd festhalten zu können. Bei diesen Greifern ist nachteilig, daß die für die Durchfederung notwendigen Freiräume durch Farbe, Papierstaub und Lack verkleben, wodurch die Federung behindert wird.According to EP 02 13 397, grippers for sheet-fed rotary printing machines have become known, the gripper fingers being fastened to metallic spring elements in order to be able to hold the sheet resiliently against a gripper support. With these grippers it is disadvantageous that the free spaces necessary for the deflection stick together with paint, paper dust and lacquer, whereby the suspension is hindered.

Weiterhin sind gemäß DE 39 14 646 Greifereinrichtungen an Bogenrotationsdruckmaschinen bekannt, bei welchen der Gelenkpunkt auf einer gedachten Verbindungslinie zwischen Greiferwellenmittelpunkt und der Vorderkante des Greiferfingers liegt. Oberhalb dieses Gelenkpunktes ist ein elastisches Polster vorgesehen, gegen welches der Greiferfinger über den Papierbogen gegen die Greiferauflage federnd gelagert ist. Nachteilig hierbei ist, daß der Gelenkpunkt beim stärkeren Durchfedern des Greifers von der gedachten Verbindungslinie auslenkt, was zum Schieben des Greifers und somit zu Ungenauigkeiten beim Greifvorgang führt. Darüberhinaus kommt es nicht zur flächenhaften Auflage des Greiferfingers auf die Greiferauflage, da der Gelenkpunkt des Greifers nicht mit dem Drehpunkt der Greiferwelle übereinstimmt.Furthermore, according to DE 39 14 646, gripper devices on sheet-fed rotary printing presses are known in which the articulation point lies on an imaginary connecting line between the center of the gripper shaft and the front edge of the gripper finger. Above this hinge point, an elastic cushion is provided, against which the gripper finger is resiliently supported via the paper sheet against the gripper pad. The disadvantage here is that the articulation point deflects from the imaginary connecting line when the gripper bounces more, which leads to pushing of the gripper and thus to inaccuracies in the gripping process. Beyond that, there is no two-dimensional support of the gripper finger on the gripper support, since the articulation point of the gripper does not match the pivot point of the gripper shaft.

Weiterhin ist die Anordnung eines elastischen Polsters in einem Spalt zwischen Greiferarm und Greiferfinger deshalb nachteilig, weil infolge der Deformation des elastischen Polsters verhältnismäßig große Druckkräfte aufgewendet werden müssen, um den Greifer in die durchgefederte Stellung zu bringen.Furthermore, the arrangement of an elastic cushion in a gap between the gripper arm and the gripper finger is disadvantageous because, due to the deformation of the elastic cushion, relatively large compressive forces have to be applied in order to bring the gripper into the spring-loaded position.

Der Erfindung liegt die Aufgabe zugrunde, einen schmutzunempfindlichen Greifer für Bogenrotationsdruckmaschinen zu schaffen, welcher auch beim Schließen schubbewegungsfrei arbeitet.The invention has for its object to provide a dirt-insensitive gripper for sheet-fed rotary printing presses, which also works without shear movement when closing.

Diese Aufgabe wird erfindungsgemäß durch den kennzeichnenden Teil des Patentanspruches 1 gelöst.This object is achieved by the characterizing part of claim 1.

Durch den Einsatz der erfindungsgemäßen Greifer für Bogenrotationsdruckmaschinen werden insbesondere dadurch Vorteile erzielt, daß eine Schmutzempfindlichkeit nicht mehr gegeben ist infolge des Wegfalls von Freiräumen für die Federelemente zur Durchfederung. Dadurch, daß der Gelenkpunkt des Greifers mit dem Drehpunkt der Greiferwelle übereinstimmt und ein elastisches Material zwischen dem Greifergehäuse und dem Klemmstück angeordnet ist, wird eine flächenhafte Auflage zwischen der Druckfläche des Greiferfingers und der Fläche der Greiferauflage erzielt.By using the grippers according to the invention for sheet-fed rotary printing machines, advantages are achieved in particular in that there is no longer any sensitivity to dirt as a result of the elimination of free spaces for the spring elements for deflection. Characterized in that the pivot point of the gripper coincides with the pivot point of the gripper shaft and an elastic material is arranged between the gripper housing and the clamping piece, an areal contact between the pressure surface of the gripper finger and the surface of the gripper support is achieved.

Durch die Wirkung von Schubkräften auf das elastische Material zwischen dem Greifergehäuse und dem Klemmstück erfolgt keine Querschnittsveränderung beim elastischen Material, so daß sich die aufzuwendende Kraft für den Greifer in etwa proportional verhält zum zurückzulegenden Weg.Due to the effect of shear forces on the elastic material between the gripper housing and the clamping piece, there is no change in the cross-section of the elastic material, so that the force to be applied for the gripper is approximately proportional to the distance to be covered.

Weitere Vorteile bestehen darin, daß das elastische Material der erfindungsgemäßen Greifer auch gegen Hitze unempfindlich ist, so daß diese mit Vorteil auch bei Maschinen mit Trocknern eingesetzt werden können. Auch ist es möglich, das elastische Material so zu gestalten, daß es resistent ist gegen Fette und Waschmittel, so daß die erfindungsgemäßen Greifer auch ohne Probleme in Druckwerken eingesetzt werden können.Further advantages are that the elastic material of the grippers according to the invention is also insensitive to heat, so that they can also be used advantageously in machines with dryers. It is also possible to design the elastic material so that it is resistant to greases and detergents, so that the grippers according to the invention can also be used in printing units without problems.

Bei der Funktion des Greifers wird die Federwirkung durch eine Schubbeanspruchung des elastischen Materials erzielt. Infolge des Wegfalls von Freiräumen zwischen den Federelementen können sich in diesen auch keine Schmutzpartikel absetzen. Beim Einsatz von Naturkautschuk als elastischem Material sind eine hohe Zugfestigkeit, eine gute Elastizität und geringe Verschleißerscheinungen von Vorteil. Eine ebenfalls gute Dämpfungseigenschaft des elastischen Materials, verbunden mit hoher Zugfestigkeit und Bruchdehnung bei einer guten Beständigkeit gegen Öle und Waschmittel wird erzielt, wenn Polyurethan mit einer Härte von 70° bis 90° Shore eingesetzt wird. Sollen Greifer mit hoher Alterungs- und Hitzebeständigkeit ausgestattet sein, dann empfiehlt sich die Verwendung von Silicon-Kautschuk als elastisches Material. Dies trifft immer dann zu, wenn die Greifer in Kettenauslegern bei Maschinen mit Trocknern zum Einsatz kommen. Schließlich ist es auch noch von Vorteil, wenn Chloroprene-Kautschuk als elastisches Material eingesetzt wird. Dies kann der Fall sein, wenn die Greifer oft mit Ölen oder Waschmitteln in Berührung kommen.When the gripper is functioning, the spring action is achieved by pushing the elastic material. As a result of the absence of free spaces between the spring elements, no dirt particles can settle in them. When using natural rubber as an elastic material, high tensile strength, good elasticity and low signs of wear are advantageous. An equally good damping property of the elastic material, combined with high tensile strength and elongation at break with good resistance to oils and detergents is achieved when polyurethane with a hardness of 70 ° to 90 ° shore is used. If grippers are to be equipped with high aging and heat resistance, then the use of silicone rubber as an elastic material is recommended. This is always the case when the grippers are used in chain brackets on machines with dryers. Finally, it is also advantageous if chloroprene rubber is used as the elastic material. This can be the case if the grippers often come into contact with oils or detergents.
