Auf dem Bändertisch 1/Anlegtisch 4 sind ein auszurichtender Bogen 6 und ein Folgebogen 7 gezeigt. Dem Anlegtisch 4 ist ein Vorgreifer 8 und diesem ein Zylinder 9 nachgeordnet, der ein Bogenhaltesystem 33 aufeist. Der Vorgreifer 8 besteht aus in Gestellpunkten 10 schwenkbar gelagerten Schwinghebeln 11 und einem Greifersystem 12. Das Greifersystem 12 weist auf einer Greiferwelle 13 geklemmte Greiferfinger 14 auf, die mit einer Greiferaufschlagleiste 15 korrespondieren. Die Greiferwelle 13 ist in zwei Lagerkörpern 16 drehbar aufgenommen und kann mittels eines an der Greiferwelle 13 angreifenden Rollenhebels 23, der mit einer nicht dargestellten Kulisse korrespondiert, verdreht werden. Die Lagerkörper 16 sind durch ein Kastenprofil 22 miteinander verbunden. Mit dem Kastenprofil 22 und den Lagerkörpern 16 ist die Greiferaufschlagleiste 15 verbunden. Die Lagerkörper 16 sind mit Hilfe von zwei oberen Führungsrollen 17 und einer unteren Führungsrolle 18 auf Führungsschienen 19 verschiebbar gelagert. An den Lagerkörpern 16 ist jeweils ein Eingriffsglied 20 vorgesehen, das in eine in den Schwinghebeln 11 vorgesehene, in radialer Richtung verlaufende Führungsnut 21 eingreift.
Die Führungsschienen 19 sind in einem Lagerpunkt 24 schwenkbar aufgenommen, während am gegenüberliegenden, dem Anlegtisch 4 zugewandten Ende eine Stelleinrichtung 25 angreift. Im Ausführungsbeispiel ist die Stelleinrichtung 25 als Kurvengetriebe ausgebildet, dessen Rollenhebel 26 mittels einer Druckfeder 27 über eine Kurvenrolle 28 in Eingriff mit einem Kurvenkörper 29 gehalten wird. Der Rollenhebel 26 ist in einem Gestellpunkt 32 gelagert und als ternäres Glied ausgebildet, der an seinem freien Ende mit einem Abtriebsglied 30 in eine in den Führungsschienen 19 angeordnete Nut 31 eingreift.
Im Ausführungsbeispiel sind die Führungsschienen 19 im Bereich des Zylinders 9 im Lagerpunkt 24 gelagert und im Bereich des Anlegtischs 4 ist die an den Führungsschienen 19 angreifende Stelleinrichtung 25 vorgesehen. Es ist auch möglich, die Stelleinrichtung 25 im Bereich des Zylinders 9 und den Lagerpunkt 24 im Bereich des Anlegtischs 4 vorzusehen.FIG. 1 shows a belt table 1 with conveyor belts 3 rotating in the sheet transport direction 2. A feed table 4 with front marks 5 is assigned to the belt table 1. A sheet 6 to be aligned and a subsequent sheet 7 are shown on the belt table 1 / feed table 4. The feed table 4 is followed by a pre-gripper 8 and a cylinder 9, which has a sheet holding system 33. The pre-gripper 8 consists of rocking levers 11 pivotably mounted in frame points 10 and a gripper system 12. The gripper system 12 has gripper fingers 14 clamped on a gripper shaft 13, which correspond to a gripper bar 15. The gripper shaft 13 is rotatably received in two bearing bodies 16 and can be rotated by means of a roller lever 23 which engages on the gripper shaft 13 and which corresponds to a link (not shown). The bearing body 16 are connected to one another by a box section 22. The gripper bar 15 is connected to the box section 22 and the bearing bodies 16. The bearing bodies 16 are mounted on guide rails 19 so as to be displaceable with the aid of two upper guide rollers 17 and a lower guide roller 18. An engagement member 20 is provided on the bearing bodies 16, which engages in a guide groove 21 provided in the rocker arms 11 and extending in the radial direction.
The guide rails 19 are pivotally received in a bearing point 24, while an actuating device 25 engages at the opposite end facing the feed table 4. In the exemplary embodiment, the actuating device 25 is designed as a cam mechanism, the roller lever 26 of which is held in engagement with a cam body 29 by means of a compression spring 27 via a cam roller 28. The roller lever 26 is mounted in a frame point 32 and is designed as a ternary link which, at its free end, engages with a driven member 30 in a groove 31 arranged in the guide rails 19.
In the exemplary embodiment, the guide rails 19 are mounted in the area of the cylinder 9 in the bearing point 24 and in the area of the feed table 4 the actuating device 25 acting on the guide rails 19 is provided. It is also possible to provide the actuating device 25 in the area of the cylinder 9 and the bearing point 24 in the area of the feed table 4.

Das zur Verarbeitung gelangende Bogenmaterial wird von einem nicht dargestellten Bogenanleger vereinzelt und dem Bändertisch 1 zugeführt und von diesem auf den Anlegtisch 4 und mit der Vorderkante gegen die in einer Position am Anlegtisch 4 befindlichen Vordermarken 5 transportiert. Entsprechend wurde der auszurichtende Bogen 6 in Fig. 1 nach der Vorderkante ausgerichtet. Nach dem Ausrichten nach der Vorderkante wird der auszurichtende Bogen 6 von dem in eine Übernahmeposition am Anlegtisch 4 geführte Greifersystem 12 erfasst und nach dem Wegführen der Vordermarken 5 in eine Position unter den Anlegtisch 4 zur Übergabeposition transportiert. Dabei erfolgt der Transport des auszurichtenden Bogens 6 auf einer geradlinigen Bahn 34. In Fig. 1 ist symbolhaft das Greifersystem 12 auf dem Weg zur Übergabeposition am Zylinder 9 dargestellt.The sheet material to be processed is from a sheet feeder, not shown isolated and fed to the belt table 1 and from there onto the feed table 4 and with the front edge against the front marks located in a position on the feed table 4 5 transported. Accordingly, the sheet 6 to be aligned in Fig. 1 was after the Aligned leading edge. After aligning to the front edge, the one to be aligned Sheet 6 from the gripper system guided into a transfer position on the feed table 4 12 detected and after leading the front marks 5 in a position under the feed table 4 transported to the transfer position. The transport to be aligned is carried out Arc 6 on a straight path 34. In Fig. 1, the gripper system 12 is symbolic the way to the transfer position shown on the cylinder 9.

Das Antreiben des Greifersystems 12 erfolgt über einen nicht dargestellten Antrieb, der den Schwinghebeln 11 eine periodische Schwenkbewegung vermittelt. Durch die Wirkpaarung Eingriffsglied 20/Führungsnut 21 werden die Lagerkörper 16 auf den Führungsschienen 19 verschoben und so eine Bewegung des Greifersystems 12 entlang der geradlinigen Bahn 34 realisiert.
Bei Erreichen der Übergabeposition, in Fig. 1 ist in dieser Position der Vorgreifer 8 dargestellt, wird der auszurichtende Bogen 6 von dem Greifersystem 12 an das Bogenhaltesystem 33 übergeben und das Greifersystem 12 über diese Position hinaus in eine Umkehrposition gesteuert, in der die Bewegungsrichtung der Schwinghebel 11 umgesteuert wird. Symbolhaft ist diese Position in Fig. 1 durch das Greifersystem 12 dargestellt. Vor dem Zurückführen des Greifersystems 12 an den Anlegtisch 4 zur Übernahme des Folgebogens 7 werden die Führungsschienen 19 durch die Stelleinrichtung 25 in Uhrzeigersinn um den Lagerpunkt 24 geschenkt, so dass das Greifersystem 12 zurück zum Anlegtisch 4 einer Bahn 35 folgt, die in einem Abstand unterhalb der geradlinigen Bahn 34 vorgesehen ist. In Figur 1 ist das durch ein gestricheltes Greifersystem 12 symbolhaft dargestellt. Vor Erreichen des Anlegtischs 4 werden durch die Stelleinrichtung 25 die Führungsschienen 19 zurückgeschwenkt. Damit ist das Greifersystem 12 bereit zur Übernahme des Folgebogens 7.
Es ist auch möglich, wenn z.B. die Stelleinrichtung 25 als Kurvengetriebe ausgebildet ist, dem Kurvenkörper 29 ein Bewegungsgesetz aufzuprägen, so dass sich die translatorische Bewegung des Greifersystems 12 bei der Bewegung zurück zum Anlegtisch 4 und die durch den Kurvenkörper 29 initiierte Schwenkbewegung überlagern und damit das Greifersystem 12 einer beliebig gestalteten Bahn unterhalb der geradlinigen Bahn 34 folgt.
Im Ausführungsbeispiel wurde ein Anlegtisch 4 mit Vordermarken 5 zum Ausrichten nach der Vorderkante vorgesehen. Es ist auch möglich, statt die Vordermarken 5 am Anlegtisch 4 vorzusehen, diese dem Greifersystem 12 zuzuordnen und die Bogen im Greifersystem nach der Vorderkante und ggf. nach der Seitenkante auszurichten, indem das Greifersystem 12 quer zur Bogentransportrichtung verschoben wird. The gripper system 12 is driven by a drive, not shown, which provides the rocker arms 11 with a periodic pivoting movement. Due to the active pairing of the engagement member 20 / guide groove 21, the bearing bodies 16 are displaced on the guide rails 19, and thus a movement of the gripper system 12 along the straight path 34 is realized.
When the transfer position is reached, in FIG. 1 the pre-gripper 8 is shown in this position, the sheet 6 to be aligned is transferred from the gripper system 12 to the sheet holding system 33 and the gripper system 12 is controlled beyond this position into a reversing position in which the direction of movement of the Rocker arm 11 is reversed. This position is symbolically represented in FIG. 1 by the gripper system 12. Before returning the gripper system 12 to the feed table 4 for taking over the following sheet 7, the guide rails 19 are given clockwise by the adjusting device 25 around the bearing point 24, so that the gripper system 12 follows a path 35 back to the feed table 4, which is at a distance below the rectilinear path 34 is provided. In Figure 1, this is symbolically represented by a dashed gripper system 12. Before the feed table 4 is reached, the guide rails 19 are pivoted back by the actuating device 25. The gripper system 12 is thus ready to take over the following sheet 7.
It is also possible, if, for example, the actuating device 25 is designed as a cam mechanism, to impose a law of motion on the cam body 29, so that the translational movement of the gripper system 12 during the movement back to the feed table 4 and the swiveling movement initiated by the cam body 29 overlap and thus that Gripper system 12 follows an arbitrarily designed path below the straight path 34.
In the exemplary embodiment, a feed table 4 with front marks 5 was provided for alignment with the front edge. It is also possible, instead of providing the front marks 5 on the feed table 4, assigning them to the gripper system 12 and aligning the sheets in the gripper system according to the front edge and, if appropriate, to the side edge, by displacing the gripper system 12 transversely to the sheet transport direction.
