Description

Die Erfindung betrifft eine Antriebsvorrichtung eines Vorgreifers mit einem Greifersystem zum Transport von Bogen von einem Anlegtisch zu einem Bogenhaltesystem eines Zylinders, wobei das Greifersystem bei seiner Bewegung eine geradlinige Bahn beschreibt, wobei das Greifersystem auf Führungsschienen verschiebbar gelagert ist, die sich mindestens vom Anlegtisch bis in den Bereich des Zylinders erstrecken.The invention relates to a drive device of a pregripper with a gripper system for transporting sheets from a feed table to a sheet holding system of a cylinder, wherein the gripper system describes a rectilinear path during its movement, wherein the gripper system is slidably mounted on guide rails extending at least from the feed table to extend the region of the cylinder.

Aus der DE 100 13 006 A1 ist es bekannt, das Greifersystem eines Vorgreifers sowohl zwischen einer Übernahmeposition am Anlegtisch und einer Übergabeposition am nachgeordneten Zylinder als auch zurück zur Übernahmeposition auf einer geradlinigen Bahn zu führen, wobei die Bahnverläufe identisch sind.From DE 100 13 006 A1 it is known to guide the gripper system of a pregripper both between a transfer position on the feed table and a transfer position on the downstream cylinder and back to the transfer position on a straight line, the tracks are identical.

Nachteilig ist, dass zusätzlich Mittel vorgesehen werden müssen, um eine Kollision des Greifersystems des Vorgreifers mit dem Zylinder bei der Rückführung zur Übernahmeposition auszuschließen. Außerdem ist es von Nachteil, dass das freie Ende des von den Bogenhalteelementen des Zylinders geführten Bogens mit dem zur Übernahmeposition zurückkehrenden Greifersystems kollidiert, was zu Beschädigungen eines auf der Rückseite befindlichen Drucks oder zu Bogenbeschädigungen führen kann.The disadvantage is that additional means must be provided to preclude a collision of the gripper system of the pregripper with the cylinder in the return to the takeover position. Furthermore, it is disadvantageous that the free end of the sheet guided by the sheet-holding elements of the cylinder collides with the gripper system returning to the transfer position, which can lead to damage of a printing on the back or to bow damage.

In der FR 1312813 wird ein Vorgreifer mit einem Greiferstem beschrieben, das zwischen dem Anlegtisch und dem nachgeordneten Zylinder auf einer ersten Kreisbahn geführt wird. Dazu ist der Vorgreifer in einem Gestellpunkt gelagert und wird periodisch um diesen geschwenkt. Der Gestellpunkt ist zusätzlich mit einer stellbaren Exzentrizität versehen, so dass die Rückführung des Greifersystems zum Anlegtisch auf einer zweiten kreisförmigen Bahn erfolgt, die beabstandet unterhalb der ersten Bahn verläuft.In FR 1312813 a pre-gripper with a gripper bar is described, which is guided between the feed table and the downstream cylinder on a first circular path. For this purpose, the pre-gripper is mounted in a frame point and is periodically pivoted about this. The frame point is additionally provided with an adjustable eccentricity, so that the return of the gripper system to the feed table takes place on a second circular path, which extends at a distance below the first path.

Aufgabe der Erfindung ist es, eine gattungsgemäße Antriebsvorrichtung eines Vorgreifers dahingehend zu verändern, dass mit einfachen Mitteln eine problemlose Rückführung des Greifersystems zur Übernahmeposition möglich und eine Kollision mit dem zur Verarbeitung gelangenden Bedruckstoff vermieden wird.The object of the invention is to modify a generic drive device of a pregripper to the effect that with simple means a problem-free return of the gripper system for takeover position possible and a collision with the reaching for processing substrate is avoided.

Erfindungsgemäß wird die Aufgabe durch einen Antrieb gemäß den Merkmalen des Anspruchs 1 gelöst.According to the invention the object is achieved by a drive according to the features of claim 1.

Durch die erfindungsgemäße Lösung ist es möglich, mit einfachen Mitteln das Greifersystem so zu steuern, dass ein problemloses Rückführen des Greifersystems zum Anlegtisch möglich ist, wobei eine Kollision des Verarbeitungsgutes mit dem Greifersystem vermieden wird.The solution according to the invention makes it possible to control the gripper system with simple means in such a way that it is possible to return the gripper system to the feed table without difficulty, avoiding a collision of the material to be processed with the gripper system.

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 separated by a sheet feeder, not shown, and fed to the belt table 1 and transported by this on the feed table 4 and with the leading edge against the front marks 5 located in a position on the feed table 4. Accordingly, the sheet 6 to be aligned was aligned in Fig. 1 after the leading edge. After alignment after the leading edge of the sheet 6 to be aligned is detected by the guided in a takeover position on the feed table 4 gripper system 12 and after the removal of the leading brands 5 in a position below the feed table 4 transported to the transfer position. In this case, the transport of the sheet 6 to be aligned takes place on a rectilinear path 34. FIG. 1 symbolically shows the gripper system 12 on the way to the transfer position 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 Antegtisch 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 driving of the gripper system 12 via a drive, not shown, which gives the rocker arms 11 a periodic pivoting movement. By the active pair engagement member 20 / guide 21, the bearing body 16 are moved on the guide rails 19 and so realized a movement of the gripper system 12 along the linear path 34.
Upon reaching the transfer position, in Fig. 1, the pre-gripper 8 is shown in this position, the sheet to be aligned 6 is transferred from the gripper system 12 to the sheet holding system 33 and the gripper system 12 controlled beyond this position out in a reversing position in which the direction of movement of the Swing lever 11 is reversed. Symbolically, this position is shown in Fig. 1 by the gripper system 12. Before returning the gripper system 12 to the feed table 4 to take over the subsequent sheet 7, the guide rails 19 are given by the actuator 25 in a clockwise direction about the bearing point 24, so that the gripper system 12 back to the Antegtisch 4 a track 35 follows, at a distance below the straight line 34 is provided. In FIG. 1, this is shown symbolically by a dashed gripper system 12. Before reaching the feed table 4, the guide rails 19 are swung back by the adjusting device 25. Thus, the gripper system 12 is ready to take over the next sheet. 7
It is also possible if, for example, the adjusting device 25 is designed as a cam gear 29 impose a law of motion on the cam body 29, so that superimpose the translational movement of the gripper system 12 in the movement back to the feed table 4 and initiated by the cam body 29 pivotal movement and thus the Gripper system 12 follows an arbitrarily shaped path below the rectilinear path 34.
In the exemplary embodiment, a feed table 4 was provided with front marks 5 for aligning with the leading edge. It is also possible, instead of providing the front marks 5 on the feed table 4, to assign them to the gripper system 12 and to align the sheets in the gripper system according to the front edge and, if necessary, the side edge by moving the gripper system 12 transversely to the sheet transport direction.
