Abstract
Description
Eine Übertragungstrommel zum Fördern eines Bogens enthält mindestens ein Greifersystem zum Halten eines Bogens an dessen vorderen oder nachlaufenden Rand. Bei pneumatischen Greifersystemen werden die Bogen durch Unterdruck auf einer Saugleiste gehalten. Mechanische Greifersysteme enthalten in Reihe angeordnete Greiferfinger, die jeweils mit einer Greiferauflage zusammenwirken. Die Saugleisten bzw. die Greiferauflagen befinden sich in Richtung senkrecht zur Rotationsachse der Übertragungstrommel auf einer radialen Höhe, die eine passergerechte Übernahme bzw. Übergabe von bzw. an eine benachbarte Trommel sicherstellt. Um eine Anpassung an die Bogendicke zu erreichen, ist es bekannt, die Greiferauflagen einzeln oder in Gruppen radial zu stellen.A transfer drum for conveying a sheet includes at least one gripper system for holding a sheet at its leading or trailing edge. In pneumatic gripper systems, the sheets are held by vacuum on a squeegee. Mechanical gripper systems include serially arranged gripper fingers which each cooperate with a gripper pad. The suction strips or the gripper pads are located in the direction perpendicular to the axis of rotation of the transfer drum at a radial height, which ensures a passport-appropriate transfer or transfer from or to an adjacent drum. In order to achieve an adaptation to the sheet thickness, it is known to provide the gripper pads individually or in groups radially.

Aufgabe der Erfindung ist es, eine Übertragungstrommel zum Fördern eines Bogens entwickeln, bei der die Zuverlässigkeit einer Greiferflächenhöhenverstellung verbessert ist.The object of the invention is to develop a transfer drum for conveying a sheet, in which the reliability of a gripper surface height adjustment is improved.
Die Aufgabe wird mit einer Übertragungstrommel gelöst, welche die Merkmale nach Anspruch 1 aufweist. Vorteilhafte Ausgestaltungen ergeben sich aus den Unteransprüchen.The object is achieved with a transfer drum, which has the features of claim 1. Advantageous embodiments emerge from the subclaims.
Gemäß der Erfindung geschieht die Greiferflächenhöhenverstellung mit einem Keilschubgetriebe, dessen Keilschubstange mit einer Schnappanordnung gekoppelt ist. Durch die Schnappanordnung können die Greiferflächen in radialer Richtung der Übertragungstrommel in zwei stabile Einstellpositionen gebracht werden. In den Einstellpositionen kann die Keilschubstange jeweils gegen einen Anschlag liegen. Die Anschlagpositionen werden mittels der Schnappanordnung sicher erreicht, wobei beim Umschalten in die Anschlagpositionen die instabilen Zwischenstellungen schnell überfahren werden. Eine Fernverstellung der Greiferflächenhöhen kann mit einem einfachen Stellglied vorgenommen werden, welches an die Keilschubstange angreift und keine Drehdurchführung für eine Energieleitung durch den Trommelkörper benötigt.According to the invention, the gripper surface height adjustment is done with a wedge push gear, the wedge push rod is coupled with a snap arrangement. By the snap arrangement, the gripper surfaces can be brought in the radial direction of the transfer drum in two stable setting positions. In the setting positions, the wedge push rod can each lie against a stop. The stop positions are reliably achieved by means of the snap arrangement, wherein the unstable intermediate positions are quickly run over when switching to the stop positions. A remote adjustment of the gripper surface heights can be made with a simple actuator which engages the wedge push rod and does not require a rotary feedthrough for a power line through the drum body.
Die Schnappanordnung kann mittels einer Totpunktfeder, eines Kippsprungwerkes, eines Spannwerkes oder einer sogenannten Overcenter-Device bzw. einer Flip-Flop-Feder ausgeführt sein. Der Zahl der Greiferanordnungen an einem Trommelkörper entsprechend können mehrere Schnappanordnungen vorgesehen sein, die im Zusammenwirken mit Stellkurven oder Stellnocken während einer Umdrehung des Trommelkörpers betätigt werden. Ein Aktor zum Betätigen der Schnappanordnung kann trommelfest oder gestellfest angeordnet sein. Ein Einleiten der Verstellbewegung erfolgt bevorzugt bei geöffneten Greifern, so dass geringe Verstellkräfte notwendig werden.The snap arrangement can be implemented by means of a dead-center spring, a tilting jump mechanism, a clamping mechanism or a so-called overcenter device or a flip-flop spring. The number of gripper assemblies on a drum body according to several snap arrangements can be provided which are actuated in conjunction with adjusting curves or adjusting cams during a revolution of the drum body. An actuator for actuating the snap arrangement can be arranged fixed to the drum or fixed to the frame. Initiation of the adjustment movement is preferably carried out with open grippers, so that small adjustment forces are necessary.
