The side parts 12 are either not detachable Example cast or welded, or preferably detachable, for example screwed, connected to the circuit board 11 and carry the control of the gripper systems 6, 7 and Suction system 8 and the swivel shafts 15, inclusive Cam rollers 18, which are then in a known manner via control curves (Cam mechanism) are controllable.

An der Unterseite der Platine 11 ist wenigstens eine, bevorzugt sind mehrere Teilflächen 10 angeordnet, welche den am Zylindergrundkörper 9 angeordneten Teilflächen 10 benachbart zugeordnet sind. Je nach Ausbildung ist auch eine Kombination von voller Fläche 10 und Teilflächen 10 bzw. von zwei vollen Flächen 10 am Zylindergrundkörper 9 bzw. Platine 11 realisierbar. Die Teilflächen 10 von Zylindergrundkörper 9 und Unterseite der Platine 11 sind zumindest in einer Ebene angeordnet. In einer bevorzugten Ausbildung ist die Platine 11 und/oder das entsprechende Seitenteil 12 in einer weiteren Ebene am Zylindergrundkörper 9 lagerbar. Hierzu sind ebenso planparallel zur Zylinderachse 13 eine oder mehrere Zusatzflächen 17 anordbar (Fig. 2). Die Zusatzfläche 17 ist dabei am Zylindergrundkörper 9 und an der benachbart zugeordneten Unterseite der Platine 11 bzw. des Seitenteils 12 angeordnet. Die Platine 11 ist stets innerhalb des Zylinderumfanges angeordnet und stützt sich bei Bedarf an den Zusatzflächen 17 ab.At least one is preferred on the underside of the circuit board 11 are arranged several sub-areas 10, which on Cylinder base 9 arranged partial areas 10 adjacent assigned. Depending on the training, there is also a combination of full area 10 and partial areas 10 or of two full areas Surfaces 10 on the cylinder base body 9 or circuit board 11 can be realized. The partial surfaces 10 of the basic cylinder body 9 and Bottom of the board 11 are at least in one plane arranged. In a preferred embodiment, the circuit board 11 and / or the corresponding side part 12 in another Can be stored on the cylinder base 9. This also applies plane-parallel to the cylinder axis 13 one or more additional surfaces 17 can be arranged (Fig. 2). The additional surface 17 is there on the cylinder base body 9 and on the adjacent associated The underside of the circuit board 11 or the side part 12 is arranged. The board 11 is always within the cylinder circumference arranged and supported on the additional surfaces 17 if necessary from.

Mit der erfingungsgemäßen Ausbildung sind somit auf einer Platine 11 die Greifersysteme 6,7 und das Saugersystem 8 sowie die Schwenkwellen 15 mit Lagerungen 16, die zur Lagerung erforderlichen Seitenteile 12 sowie die für die Steuerung erforderlichen Kurvenrollen 18 mit Rollenhebel sowie Rückholsysteme (Federn), Anschlagelemente, Schmierungsaggregate und Axialführungselemente anordbar. Bei einer Montage ist somit die derart bestückte Platine 11 mit dem Zylindergrundkörper 9 zum Bogenführungszylinder 4 komplettierbar. Bei einer Demontage lassen sich die einzelnen Bauteile, zum Beispiel die Greiferwelle 14, von der Platine 11 austauschen oder die komplett bestückte Platine 11 wird bevorzugt vom Zylindergrundkörper 9 getrennt. Die Schnittstelle bezüglich der Trennung zwischen Platine 11 mit Bogenhaitesystemen 5 und der Steuerung ist dabei zwischen den noch auf der Platine 11 angeordneten Kurvenrollen 18 (Teil des Bogenhaltesystems 5) und den zugeordneten Steuerkurven definiert.With the training according to the invention are thus on one Circuit board 11, gripper systems 6, 7 and suction system 8 and the swivel shafts 15 with bearings 16, which are used for storage required side parts 12 and those for the control required cam rollers 18 with roller lever as well Return systems (springs), stop elements, lubrication units and axial guide elements can be arranged. During assembly, the printed circuit board 11 thus assembled with the cylinder body 9 to the sheet guiding cylinder 4 completable. When disassembling the individual Components, for example the gripper shaft 14, from the board 11 or replace the completely assembled board 11 preferably separated from the cylinder body 9. the interface regarding the separation between circuit board 11 with bow holding systems 5 and the controller is still between the arranged on the board 11 cam rollers 18 (part of the Sheet holding system 5) and the associated control curves defined.

Die beschriebene Ausführung ist nicht auf einen zweifachgroßen Bogenführungszylinder 4 mit zwei umfangsseitig angeordneten Platinen 11 mit Bogenhaltesystemen 5 beschränkt.The design described is not a double size Sheet guiding cylinder 4 with two circumferentially arranged Boards 11 with sheet holding systems 5 limited.

Vielmehr eignet sich diese Lösung auch für einen Zylindergrundkörper 9, beispielsweise einen einfachgroßen Bogenführungszylinder 4, mit nur einer Platine 11 und einem Bogenhaltesystem 5 am Umfang.
Alternativ sind auch drei- oder vierfachgroße Bogenführungszylinder 4 mit entsprechender Anzahl von symmetrisch am Umfang angeordenten Platinen 11 mit Bogenhaltesystemen 5 ausführbar.
Bei einem Bogenführungszylinder 4 mit einer Platine 11 mit Bogenhaltesystem 5 ist am Zylindergrundkörper 9 zumindest eine Fläche bzw. Teilfläche 10 angeordnet, so daß die Platine 11 mit der Unterseite (Fläche bzw. Teilfläche 10) lösbar innerhalb des Trommelumfanges fixiert ist.
Bei einem Bogenführungszylinder 4 mit mehreren Platinen 11 mit je einem Bogenhaltesystem 5 sind am Zylindergrundkörper 9 mehrere Flächen bzw. Teilflächen 10 symmetrisch um 120° (bei drei Platinen 11) bzw. um 90° (bei vier Platinen 11) umfangseitig angeordnet, so daß die Platinen 11 mit der Unterseite (Fläche bzw. Teilfläche 10) lösbar am Zylindergrundkörper 9 innerhalb des Trommelumfanges fixierbar sind.Rather, this solution is also suitable for a cylinder base body 9, for example a single-sized sheet guiding cylinder 4, with only one plate 11 and one sheet holding system 5 on the circumference.
Alternatively, triple or quadruple-sized sheet guiding cylinders 4 with a corresponding number of plates 11 arranged symmetrically on the circumference can also be designed with sheet holding systems 5.

Beispielsweise kann auf einer Platine 11 lediglich ein, z.B. als Schöndruckgreifer, ausgebildetes Greifersystem 7 mit einer gelagerten Greiferwelle 14 und wenigstens einer Kurvenrolle 18 angeordnet sein. Alternativ kann auf einer Platine 11 ein erstes und ein zweites Greifersystem 6,7 jeweils mit Greiferwelle 14 und zugeordneten Kurvenrollen 18 mit Schwenkwellen 15 (oder einem vergleichbaren Schwenkmechanismus) und zugeordneten Kurvenrollen 18 angeordnet sein.
Ebenso kann zusätzlich zu den Greifersystemen 6,7 (einschließlich Schwenkmechanismus) zumindest ein gelagertes Saugersystem 8 mit entsprechendem Bewegungsmechanismus und zugeordnter Kurvenrolle 18 angeordnet sein. Die Kurvenrollen 18 sind wiederum mit Steuerkurven in Funktionsverbindung.For example, only one gripper system 7, for example as a straight-pressure gripper, with a mounted gripper shaft 14 and at least one cam roller 18 can be arranged on a circuit board 11. Alternatively, a first and a second gripper system 6, 7, each with gripper shaft 14 and associated cam rollers 18 with swivel shafts 15 (or a comparable swivel mechanism) and associated cam rollers 18 can be arranged on a circuit board 11.
Likewise, in addition to the gripper systems 6, 7 (including swivel mechanism), at least one stored suction system 8 with a corresponding movement mechanism and associated cam roller 18 can be arranged. The cam rollers 18 are in turn functionally connected to control cams.

Das Bogenhaltesystem 5 ist zumindest durch ein Greifersystem 6 und/oder 7 gebildet, wobei wenigstens ein Greifersystem 6,7 an der Paarungsstelle von zugehöriger Kurvenrolle 18 und zugeordneter Steuerkurve vom Zylindergrundkörper 9 trennbar ist.
In Weiterbildung weist dieses Bogenhaltesystem 5 zumindest ein Saugersystem 8 auf, wobei die Saugersysteme 8 an den Paarungsstellen von Kurvenrolle 18 und zugeordneter Steuerkurve vom Zylindergrundkörper 9 trennbar sind. The sheet holding system 5 is formed at least by a gripper system 6 and / or 7, at least one gripper system 6, 7 being separable from the cylinder base body 9 at the mating point of the associated cam roller 18 and associated control cam.
In a further development, this sheet holding system 5 has at least one suction system 8, the suction systems 8 being separable from the cylinder base body 9 at the mating points of the cam roller 18 and the associated control cam.
