Description

Die Erfindung betrifft einen Vorgreifer mit einem Greifersystem zum Transport von Bogen von einem Anlegtisch zu einem Bogenhaltesystem eines Zylinders, wobei der Vorgreifer unterhalb einer Bogenbahn angeordnet ist.The invention relates to a pre-gripper with a gripper system for transporting sheets from a feed table to a sheet-holding system of a cylinder, wherein the pre-gripper is arranged below a curved path.

Bei derartigen Vorrichtungen (DE 100 23 669) ist es allgemein bekannt, das Greifersystem einem Grundkörper zuzuordnen und diesen in einer Schwingachse zu lagern. Der Grundkörper ist mit einem Antrieb zum Verschwenken gekoppelt und führt das Greifersystem zur Übernahme der einzelnen Bogen zum Anlegtisch und danach zu einem nachgeordneten Zylinder zur Übergabe des Bogens an das Bogenhaltesystem des Zylinders. Der Grundkörper ist mit dem Greifersystem unterhalb der Bahn der Bogen angeordnet, so dass dieses konvex gekrümmt umläuft und damit den Bogen eine solche Krümmung aufgezwungen wird. Diese konvexe Bogenkrümmung führt zu einer Deformation des Bogens, die Passerungenauigkeiten bedingt.In such devices (DE 100 23 669) it is generally known to assign the gripper system to a base body and to store it in a swinging axis. The main body is coupled to a drive for pivoting and guides the gripper system to take over the individual sheets to the feed table and then to a downstream cylinder for transferring the sheet to the sheet holding system of the cylinder. The main body is arranged with the gripper system below the path of the arc, so that this rotates convexly curved and thus the arc such a curvature is imposed. This convex arc curvature leads to a deformation of the arc, which causes registration inaccuracies.

Um diese Nachteile zu beseitigen, wird in der DE 100 13 006 A1 vorgeschlagen, das Greifersystem des Vorgreifers zwischen der Übernahmeposition am Anlegtisch und der Übergabeposition am nachgeordneten Zylinder auf einer geradlinigen Bahn zu führen. Damit wird zwar erreicht, dass die Bogen nicht mit einer konvexen Krümmung an das Bogenhaltesystem, sondern ungekrümmt auf einer geraden Bahn zugeführt werden, jedoch werden die Passergenauigkeit nachteilig beeinflussende Deformationen der Bogen nicht völlig ausgeschlossen.In order to eliminate these disadvantages, DE 100 13 006 A1 proposes to guide the gripper system of the pregripper on a straight path between the transfer position on the feed table and the transfer position on the downstream cylinder. This ensures that the sheets are not supplied with a convex curvature to the sheet-holding system, but unconstrained on a straight path, but the registration accuracy adversely affecting deformations of the arc are not completely excluded.

Aufgabe der Erfindung ist es, einen gattungsgemäßen Vorgreifer so auszubilden, dass die Bogen ohne eine die Passergenauigkeit nachteilig beeinflussende Deformation an das Bogenhaltesystem des Zylinders übergeben werden.The object of the invention is to provide a generic pre-gripper in such a way that the sheets are transferred to the sheet-holding system of the cylinder without a deformation adversely affecting the registration accuracy.

Erfindungsgemäß wird die Aufgabe durch einen Vorgreifer nach den Merkmalen des Anspruchs 1 gelöst.According to the invention the object is achieved by a pre-gripper according to the features of claim 1.

Durch die erfindungsgemäße Lösung ist es möglich, das zu verarbeitende Material ohne Deformation, bereits so vorgekrümmt wie es auf dem nachgeordneten Zylinder geführt wird, an das Bogenhaltesystem des Zylinders zu übergeben. Dabei ist es möglich, den Verlauf der Bogentransportbahn durch einfache Mittel an das zur Verarbeitung gelangende Material anzupassen. Durch die Anordnung der Bahn, auf der das Greifersystem vom Zylinder zum Anlegtisch zurückgeführt wird in einem Abstand unterhalb der Bogenbahn, kann das Greifersystem so geführt werden, dass eine Kollision mit dem Zylinder oder dem freien Ende des vom Bogenhaltesystem gehaltenen Bogens ausgeschlossen werden kann.By means of the solution according to the invention, it is possible to transfer the material to be processed without deformation already pre-curved as it is guided on the downstream cylinder to the sheet-holding system of the cylinder. It is possible to adapt the course of the sheet transport path by simple means to the material reaching for processing. By the arrangement of the web on which the gripper system from the cylinder to The feed table is returned at a distance below the sheet path, the gripper system can be guided so that a collision with the cylinder or the free end of the sheet held by the sheet holding system can be excluded.

In Figur 1 ist ein Bändertisch 1 mit in Bogentransportrichtung 2 umlaufenden Transportbändern 3 dargestellt. Dem Bändertisch 1 ist ein Anlegtisch 4 mit Vordermarken 5 zugeordnet. 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 26 aufweist. Der Anlegtisch 4/Bändertisch 1 sind so dem Zylinder 9 zugeordnet, dass die Ebene des Anlegtischs 4/Bändertischs 1 den Zylinder 9 schneidet. 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 angeordnete, 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.
Die Stelleinrichtung 25 besteht im Ausführungsbeispiel aus einem Stellmittel 29, das gestellfest angeordnet und über ein Stellglied 30 mit dem Ende eines als ternäres Glied ausgebildeten Rollenhebels 31 verbunden ist.FIG. 1 shows a belt table 1 with conveyor belts 3 revolving in the sheet transport direction 2. The belt table 1 is assigned a feed table 4 with front marks 5. On the belt table 1 / feed table 4, a sheet 6 to be aligned and a following sheet 7 are shown. The feed table 4 is a pre-gripper 8 and this downstream of a cylinder 9, which has a sheet holding system 26. The feed table 4 / belt table 1 are assigned to the cylinder 9 such that the plane of the feed table 4 / belt table 1 intersects the cylinder 9. The pre-gripper 8 consists of rocking levers 11 pivotally mounted in frame points 10 and a gripper system 12. The gripper system 12 has gripper fingers 14 which are clamped on a gripper shaft 13 and 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 an acting on the gripper shaft 13 roller lever 23 which corresponds to a backdrop, not shown, are rotated: The bearing body 16 are connected by a box section 22 with each other. With the box section 22 and the bearing bodies 16, the gripper bar 15 is connected. The bearing body 16 are slidably mounted on guide rails 19 by means of two upper guide rollers 17 and a lower guide roller 18. On the bearing bodies 16, an engagement member 20 is provided in each case, which engages in a arranged in the rocker arms 11, extending in the radial direction guide groove 21.
The guide rails 19 are pivotally received in a bearing point 24, while at the opposite, the feed table 4 facing the end of an actuating device 25 engages.
The adjusting device 25 is in the embodiment of an adjusting means 29 which is arranged fixed to the frame and connected via an actuator 30 with the end of a designed as a ternary member roller lever 31.

Der Rollenhebel 31 ist in einem Gestellpunkt 32 schwenkbar gelagert und greift mit einem Abtriebsglied 33 in eine in den Führungsschienen 19 angeordnete Nut ein.The roller lever 31 is pivotally mounted in a frame point 32 and engages with a driven member 33 in a arranged in the guide rails 19 a groove.

Durch die Stelleinrichtung 25 werden die Führungsschienen 19 über den Weg, den das Greifersystem 12 auf den Führungsschienen 19 zurücklegt, so verschwenkt, dass die Greiferaufschlagleiste 15/Greiferfinger 14 auf ihrem Weg vom Anlegtisch 4 zum Zylinder 9 einer Bogenbahn 27 folgen, die konkav ausgebildet ist, während die Rückführung des Greifersystems 12 zum Anlegtisch 4 auf einer Bahn 28 erfolgt, die in einem Abstand unterhalb der Bogenbahn 27 verläuft. Dabei ist es möglich, in dem Stellmittel 29 unterschiedliche Bewegungsverläufe abrufbar zu speichern und so in Abhängigkeit vom zur Verarbeitung gelangenden Bogenmaterial unterschiedliche Verläufe der Bogenbahn 27 zu realisieren.
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 Bogen 6 von dem in eine Übernahmeposition am Anlegtisch 4 geführten Greifersystem 12 erfasst und nach dem Wegführen der Vordermarken 5 in eine Position unter den Anlegtisch 4 zur Übergabeposition transportiert.
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 vom Anlegtisch 4 zum Zylinder 9 realisiert. Dabei werden die Führungsschienen 19 durch die Stelleinrichtung 25 entsprechend einem in der Stelleinrichtung 25 abgelegten Bewegungsverlauf so um den Lagerpunkt 24 geschwenkt, dass die Wirkpaarung Greiferaufschlagleiste 15/Greiferfinger 14 und damit der auszurichtende Bogen 6 auf der konkav verlaufenden Bogenbahn 27 geführt wird.By the adjusting device 25, the guide rails 19 via the path, the gripper system 12 travels on the guide rails 19, pivoted so that the Greiferaufschlagleiste 15 / gripper fingers 14 follow on their way from the feed table 4 to the cylinder 9 a curved path 27 which is concave , while the return of the gripper system 12 to the feed table 4 takes place on a web 28 which extends at a distance below the curved path 27. In this case, it is possible to store different movement profiles in the adjusting means 29 in a retrievable manner and thus to realize different courses of the arc run 27 as a function of the sheet material reaching for processing.
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 aligning to the leading edge of the sheet 6 is detected by the guided into a transfer position on the feed table 4 gripper system 12 and transported after the removal of the leading edge 5 in a position below the feed table 4 to the transfer position.
The driving of the gripper system 12 via a drive, not shown, which gives the rocker arms 11 a periodic pivoting movement. Due to the mating 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 from the feed table 4 to the cylinder 9. In this case, the guide rails 19 are pivoted by the adjusting device 25 according to a stored in the actuator 25 movement path around the bearing point 24, that the active pair gripper bar 15 / gripper fingers 14 and thus the sheet 6 to be aligned on the concave arc run 27 is performed.

In Fig. 1 ist symbolhaft das Greifersystem 12 auf dem Weg zur Übergabeposition am Zylinder 9 dargestellt.
Beim Erreichen der Übergabeposition, in Fig. 1 ist in dieser Position der Vorgreifer 8 gezeigt, wird der auszurichtende Bogen 6 von dem Greifersystem 12 an das Bogenhaltesystem 26 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.In Fig. 1, the gripper system 12 is symbolically represented on the way to the transfer position on the cylinder 9.
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 26 and the gripper system 12 is 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.

Vor dem Zurückführen des Greifersystems 12 an den Anlegtisch 4 zur Übernahme des Folgebogens 7 werden die Führungsschienen 19 abgesenkt und nachfolgend auf der im Abstand zur Bogenbahn 27 verlaufenden Bahn 28 das Greifersystem 12 zum Anlegtisch 4 geführt, wobei der Verlauf der Bahn 28 wiederum durch die Stelleinrichtung-25 gesteuert wird. In Figur 1 ist die Rückführung durch eine gestrichelte Darstellung des Greifersystems 12 symbolhaft gezeigt.Before the return of the gripper system 12 to the feed table 4 to take over the follower sheet 7, the guide rails 19 are lowered and subsequently guided on the web 28 extending in spaced relation to the sheet 27, the gripper system 12 to the feed table 4, wherein the course of the web 28 in turn by the adjusting device -25 is controlled. In Figure 1, the return is shown symbolically by a dashed line of the gripper system 12.

In Fig. 2 ist eine weitere Ausführungsform des Vorgreifers 8 mit einem Anlegtisch 4/Bändertisch 1 dargestellt. Abweichend vom Ausführungsbeispiel gem. Fig. 1 schneidet die durch den Anlegtisch 4/Bändertisch 1 gebildete Ebene nicht den Zylinder 9, sondern verläuft in einem Abstand dazu. Auch bei dieser Zuordnung des Anlegtischs 4/Bändertischs 1 werden die Bogen 6,7 durch das Greifersystem 12 auf einer konkav ausgebildeten Bogenbahn 27 zum Zylinder 9 transportiert und das Greifersystem 12 auf der in einem Abstand unterhalb der Bogenbahn 27 vorgesehenen Bahn 28 zum Anlegtisch 4 zurückgeführt.
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.FIG. 2 shows a further embodiment of the pre-gripper 8 with a feed table 4 / belt table 1. Deviating from the embodiment gem. Fig. 1 does not intersect the plane formed by the feed table 4 / belt table 1 the cylinder 9, but extends at a distance therefrom. Also in this assignment of the feed table 4 / belt table 1, the sheet 6,7 are transported by the gripper system 12 on a concave curved path 27 to the cylinder 9 and the gripper system 12 is returned to the provided at a distance below the sheet path 27 web 28 to feed table 4 ,
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.
