Abstract

The guide system has a feed table (1) fitted with front edge (4) and top surface (5) stops. Swinging system (8) takes sheets from this, accelerates them to speed of the machine and transfers them to transfer drum (9). Guide strips (11) are mounted on shaft (14) across width of drum which can be pivoted so that sheets are transferred from gripper points (7.1) of swing system and guided around drum. The novelty is that the guide strips can be moved axially along the shaft.

Description

Die Erfindung betrifft eine Bogenleiteinrichtung in der Bogenanlage von Druckmaschinen mit einer von unten arbeitenden Schwinganlage, die einen auf einem der Schwinganlage vorgeordneten Anlegetisch mit Hilfe von aus Deck- und Vordermarken bestehenden Anlegemarken nach der Vorderkante ausgerichteten Bogen erfasst, auf Maschinengeschwindigkeit beschleunigt und an eine nachgeordnete Übergabetrommel übergibt, wobei unterhalb der von den Greiferspitzen der Greifer der Schwinganlage beschriebenen Bahn eine aus über die Bogenbreite auf einer Welle verteilt angeordneten Bogenleitzungen bestehende Bogenleiteinrichtung vorgesehen ist, die durch Schwenken der Welle in eine solche Lage verbringbar ist, dass die der Unterseite eines abziehenden Bogens zugewandte Fläche der Bogenleiteinrichtung mindestens gerade noch über der von den Greiferspitzen der Schwinganlage und den Deckmarken beschriebenen Bahnen verläuft.The invention relates to a sheet guide device in the sheet line of printing presses a vibrating system working from below, one upstream of the vibrating system Feed table with the help of feed marks consisting of cover and front marks sheet aligned with the leading edge, accelerated to machine speed and passes to a downstream transfer drum, below that of the gripper tips of the gripper of the vibratory system described one from over the Sheet width on a shaft distributed sheet lines existing sheet guiding device is provided, which can be brought into such a position by pivoting the shaft is that the surface of the sheet guiding device facing the underside of a pulling sheet at least just above that of the gripper tips of the vibration system and the courses described the cover marks runs.

Eine derartige Bogenleiteinrichtung ist aus der DE 43 22 416 C2 bekannt. Die Bogenleitzungen der Bogenleiteinrichtung sind über die maximale Bogenbreite im Abstand zueinander zwischen den Greifern der Schwinganlage verteilt auf einer gemeinsamen Welle verdrehfest angeordnet und werden durch eine Stelleinrichtung periodisch aus einer unterhalb der von den Greiferspitzen der Schwinganlage beschriebenen Bahn gelegenen Position in eine über dieser Bahn gelegenen Position geschwenkt.Such a sheet guiding device is known from DE 43 22 416 C2. The arch lines of the sheet guide device are spaced apart from one another by the maximum sheet width distributed between the grippers of the vibration system on a common shaft in a torsion-proof manner are arranged and are periodically adjusted by an adjusting device from a below that of the position described the gripper tips of the vibratory system in a position above this position located pivoted.

Nachteilig ist bei dieser Bogenleiteinrichtung, dass es bei der Verarbeitung von Bogen innerhalb des Formatbereiches, wenn die seitlichen Randbereiche nur geringfügig auf den jeweiligen Bogenleitzungen aufliegen, zu Verspannungen der Bogen kommt. Das führt bei der nachfolgenden Weiterverarbeitung zur Faltenbildung und zum Doublieren.The disadvantage of this sheet guiding device is that it is within the processing of sheets of the format area, if the lateral edge areas only slightly on the respective Arch lines rest on, the arch is tense. That leads to the subsequent processing for wrinkling and doubling.

Aufgabe der Erfindung ist es, eine gattungsgemäße Bogenleiteinrichtung derart auszubilden, dass eine problemlose Verarbeitung aller innerhalb eines Formatbereiches anfallenden Bogen möglich ist.The object of the invention is to design a generic sheet guide device in such a way that that problem-free processing of all sheets within a format range is possible.

Erfindungsgemäß wird die Aufgabe durch eine Bogenleiteinrichtung gem. Anspruch 1 gelöst.According to the invention, the object is achieved by a sheet guiding device. Claim 1 solved.

Durch die erfindungsgemäße Lösung ist es möglich, den abziehenden Bogen so zu führen, dass eine Berührung der Bogenunterseite durch die zurückschwingenden Greiferspitzen sowie durch die Deckmarken vermieden wird und gleichzeitig unabhängig von der Bogenbreite auch im Randbereich eine sichere Bogenführung zu realisieren, so dass der Bogen unverspannt einer nachgeordneten Druckmaschine zugeführt werden kann. The solution according to the invention makes it possible to guide the pulling sheet in such a way that a touch of the underside of the sheet by the swinging back gripper tips as well is avoided by the cover marks and at the same time regardless of the sheet width to achieve a safe arch guidance also in the edge area, so that the arch is unstressed can be fed to a downstream printing press.

Die Erfindung soll nachstehend an einem Ausführungsbeispiel näher erläutert werden.

a partial representation acc. Fig. 1 in top view.

In Fig. 1 ist schematisch in Seitenansicht ein Anlegtisch 1 mit einem Bogen 2 und einem Folgebogen 3 dargestellt. In ihrer Position am Anlegtisch 1 ist eine aus Vordermarke 4 und Deckmarke 5 bestehende Anlegmarke 6 gezeigt, während die gestrichelte Darstellung die Position der Anlegmarke 6 unterhalb des Anlegtisches wiedergibt. Am Anlegtisch 1 ist weiterhin ein Greifer 7 einer Schwinganlage 8 dargestellt. Der Schwinganlage 8 ist eine Greifer 10 aufweisende Übergabetrommel 9 nachgeordnet, die im Lagerpunkt 19 gelagert ist. Konzentrisch zum Lagerpunkt 19 sind unterhalb der Übergabetrommel 9 ortsfest und starr Bogenleitelemente 11 angeordnet.
Den Bogenleitelementen 11 ist eine Bogenleiteinrichtung 13 zugeordnet, die sich unterhalb der von den Spitzen 7.1 der Greifer 7 auf ihrem Weg zwischen dem Anlegtisch 1 und der Übergabetrommel 9 beschriebenen Bahn erstreckt und etwa bis zum Anlegtisch 1 reicht. Die Bogenleiteinrichtung 13 besteht aus über die max. Bogenbreite verteilt angeordneten Bogenleitzungen 20, die drehfest mit einer parallel zur Übergabetrommel 9 vorgesehenen Welle 14 verbunden sind, die in einem Lagerpunkt 12 drehbar angeordnet ist und mittels eines drehfest auf der Welle 14 geklemmten Rollenhebels 15 über eine Rolle 18 und eine Zugfeder 16 in Wirkverbindung mit einer Kurvenscheibe 17 gehalten wird. Durch die Kurvenscheibe 17 kann über die Rolle 18 und den Rollenhebel 15 die Welle 14 geschwenkt und damit die Bogenleitzungen 20 der Bogenleiteinrichtung 13 in eine Lage bewegt werden, in der die Oberseite der Bogenleiteinrichtung 13 über der durch die Greiferspitzen 7.1 der Greifer 7 bei der Bewegung zur Übergabetrommel 9 beschriebenen Bahn und über den in der Position am Anlegtisch 1 befindlichen Deckmarken 5 verläuft (gestrichelte Darstellung in Fig. 1).In Fig. 1, a feed table 1 is shown schematically in side view with a sheet 2 and a subsequent sheet 3. In its position on the feed table 1, a feed mark 6 consisting of front mark 4 and cover mark 5 is shown, while the broken line shows the position of the feed mark 6 below the feed table. A gripper 7 of a vibrating system 8 is also shown on the feed table 1. The vibrating system 8 is followed by a gripper 10 having a transfer drum 9, which is mounted in the bearing point 19. Concentric to the bearing point 19 are arranged below the transfer drum 9 stationary and rigid sheet guide elements 11.
The sheet guiding elements 11 are assigned a sheet guiding device 13 which extends below the path described by the tips 7.1 of the grippers 7 on their way between the feed table 1 and the transfer drum 9 and extends approximately to the feed table 1. The sheet guiding device 13 consists of the max. Sheet lines 20 are arranged in a width-distributed manner and are connected in a rotationally fixed manner to a shaft 14 provided parallel to the transfer drum 9, which is rotatably arranged in a bearing point 12 and by means of a roller lever 15 which is non-rotatably clamped on the shaft 14 via a roller 18 and a tension spring 16 in operative connection with a cam 17 is held. By means of the cam plate 17, the shaft 14 can be pivoted via the roller 18 and the roller lever 15 and thus the arc lines 20 of the arc guide device 13 can be moved into a position in which the upper side of the arc guide device 13 is above the gripper tips 7.1 of the gripper 7 during the movement to the transfer drum 9 described path and over the cover marks 5 located in the position on the feed table 1 (dashed line in Fig. 1).

In Figur 2 ist insbesondere die Anordnung der Bogenleitzungen 20 auf der Welle 14 gezeigt. Auf der Welle 14 sind beidseitig einer Maschinenmitte 21 eine erste Hülse 22 und eine zweite Hülse 23 vorgesehen, die mit der Welle 14 drehfest aber in axialer Richtung verschiebbar verbunden sind. Auf den Hülsen 22; 23 sind die Bogenleitzungen 20 z.B. mittels einer Klemmverbindung verdrehfest angeordnet. Mit der Welle 14 ist weiterhin biegesteif ein Lagerstück 24 verbunden, in dem ein doppelt wirksames Stellelemente 25 fixiert ist. Das Stellelemente 25 greift über ein erstes Stellglied 26 an einem ersten Stellhebel 28, der mit der ersten Hülse 22 verbunden ist, an. Weiterhin greift das Stellelemente 25 über ein zweites Stellglied 27 an einem zweiten Stellhebel 29 an, der mit der zweiten Hülse 23 verbunden ist. Durch Betätigen des Stellelements 25 können die Hülsen 22; 23 über das erste Stellglied 26 und den ersten Stellhebel 28 bzw. über das zweite Stellglied 27 und den zweiten Stellhebel 29 von der Maschinenmitte 21 zu den Seiten oder zurück zur Maschinenmitte 21 verschoben werden.
Der Bogen 2 und der Folgebogen 3 werden von einem nicht dargestellten Bändertisch gegen die in der Position am Anlegtisch 1 befindlichen Anlegmarken 6 gefördert, von den Deckmarken 5 gefangen und an den Vordermarken 4 nach der Vorderkante ausgerichtet.
Nach dem Erfassen des Bogens 2 durch die Greifer 7 der Schwinganlage 8 werden die Anlegmarken 6 in eine Position unter dem Anlegtisch 1 geschwenkt (gestrichelte Darstellung in Fig. 1) und der Bogen 2 zur Übergabetrommel 9 transportiert. Während dieser Zeit, der abziehende Bogen wird noch auf dem Anlegtisch 1 geführt, werden die Anlegmarken 6 zum Anlegtisch 1 zum Ausrichten des Folgebogens 3 zurückgeschwenkt, wobei gleichzeitig die Welle 14 im Lagerpunkt 12 verdreht wird, so dass die Bogenleitzungen 20 der Bogenleiteinrichtung 13 in eine solche Lage gebracht werden, dass die der Unterseite der Bogen zugewandte Fläche der Bogenleiteinrichtung 13 mindestens gerade noch über der durch die Bewegung der Greiferspitzen 7.1 beschriebenen Bahn und im Bereich der Anlegmarken 6 über der oberen Seite der Deckmarken 5 liegt. Dadurch wird eine Berührung und damit Beschädigung der Unterseite des abziehenden Bogens 1 durch die in ihre Position am Anlegtisch 1 schwingenden Anlegmarken 6 ausgeschlossen. Nach Übergabe des Bogens 1 an die Greifer 10 schwingen die Schwinganlage 8 und damit die Greifer 7 zur Übernahme des Folgebogens 2 zurück zum Anlegtisch 1, wobei eine Berührung der Unterseite des abziehenden Bogens 1 durch die Greiferspitzen 7.1 aufgrund der noch über der Bahn der Greiferspitzen 7.1 positionierten Bogenleitzungen 20 der Bogenleiteinrichtung 13 ebenfalls vermieden wird. Nachdem das Ende des abziehenden Bogens 2 den Bereich der Bogenleiteinrichtung 13 verlassen hat, wird diese in ihre Lage unterhalb der Bahn der Greiferspitzen 7.1 geschwenkt und der Folgebogen 3 zur Übergabetrommel 9 transportiert.
Aufgrund der innerhalb eines Formatbereiches anfallenden unterschiedlichen Bogenbreiten ist es möglich, wie in Fig. 2 gezeigt, dass die Bogenrandbereiche die Bogenleitzungen 20 gerade berühren oder geringfügig auf diesen aufliegen, was zu Verspannungen der Bogen und damit zur Makulaturbildung führt. Um das zu vermeiden, werden die Hülsen 22; 23 durch das Stellelement 25 zur Maschinenmitte 21 hin verschoben, bis die mit den Bogenrandbereichen korrespondierenden Bogenleitzungen diese vollflächig tragen.FIG. 2 shows in particular the arrangement of the arch lines 20 on the shaft 14. On the shaft 14, a first sleeve 22 and a second sleeve 23 are provided on both sides of a machine center 21, which are connected to the shaft 14 in a rotationally fixed but displaceable manner in the axial direction. On the sleeves 22; 23, the arch lines 20 are arranged in a rotationally fixed manner, for example by means of a clamp connection. A bearing piece 24 is also rigidly connected to the shaft 14, in which a double-acting adjusting element 25 is fixed. The actuating elements 25 engage via a first actuating element 26 on a first actuating lever 28, which is connected to the first sleeve 22. Furthermore, the actuating elements 25 engage via a second actuator 27 on a second actuating lever 29 which is connected to the second sleeve 23. By actuating the actuating element 25, the sleeves 22; 23 can be moved from the machine center 21 to the sides or back to the machine center 21 via the first actuator 26 and the first control lever 28 or via the second actuator 27 and the second control lever 29.
The sheet 2 and the subsequent sheet 3 are conveyed by a belt table, not shown, against the feed marks 6 in the position on the feed table 1, caught by the cover marks 5 and aligned with the front marks 4 according to the leading edge.
After the sheet 2 has been gripped by the grippers 7 of the vibration system 8, the contact marks 6 are pivoted into a position under the feed table 1 (dashed line in FIG. 1) and the sheet 2 is transported to the transfer drum 9. During this time, the pulling sheet is still guided on the feed table 1, the feed marks 6 are pivoted back to the feed table 1 for aligning the following sheet 3, the shaft 14 being rotated in the bearing point 12 at the same time, so that the sheet conductors 20 of the sheet guiding device 13 into one such a position that the surface of the sheet guiding device 13 facing the underside of the sheet is at least just above the path described by the movement of the gripper tips 7.1 and in the area of the application marks 6 above the upper side of the cover marks 5. As a result, contact and thus damage to the underside of the pulling sheet 1 is prevented by the contact marks 6 which vibrate into their position on the feed table 1. After the sheet 1 has been handed over to the grippers 10, the vibrating system 8 and thus the grippers 7 swing back to the feed table 1 to take over the following sheet 2, with the gripper tips 7.1 touching the underside of the pulling sheet 1 due to the still above the path of the gripper tips 7.1 positioned sheet lines 20 of the sheet guide 13 is also avoided. After the end of the pulling sheet 2 has left the area of the sheet guiding device 13, it is pivoted into its position below the path of the gripper tips 7.1 and the following sheet 3 is transported to the transfer drum 9.
Due to the different sheet widths occurring within a format area, it is possible, as shown in FIG. 2, that the sheet edge areas just touch the sheet lines 20 or lie slightly on them, which leads to tension in the sheets and thus to waste formation. To avoid this, the sleeves 22; 23 displaced by the adjusting element 25 towards the machine center 21 until the arc lines corresponding to the arc edge regions carry the full area.

Es ist auch möglich, da lediglich das Erfordernis besteht, die im der Maschinenmitte 21 abgewandten Bereich vorgesehenen Bogenleitzungen 20 zu verstellen, nur diese auf den Hülsen 22; 23 vorzusehen und die im der Maschinenmitte 21 zugewandten Bereich direkt auf der Welle 14 verdrehfest anzuordnen. It is also possible since there is only the requirement that those facing away from the machine center 21 To adjust the area provided sheet lines 20, only these on the sleeves 22; 23 to be provided and the area facing the machine center 21 directly on to arrange the shaft 14 so that it cannot rotate.
