Description

Die Erfindung betrifft eine Einrichtung zum Umstellen eines Greifersystems in einer Wendetrommel einer Bogendruckmaschine, die wahlweise im Schöndruck oder im Schön- und Widerdruck betrieben werden kann und an der das Greifersystem bei Betriebsartwechsel von Schöndruck auf Schön- und Widerdruck und umgekehrt umgestellt werden muss.The invention relates to a device for changing over a gripper system in a turning drum of a sheet-fed press, which can be operated either in straight printing or perfecting and on which the gripper system must be changed in mode change from Perfecting to perfecting and vice versa.

Aus der DE 43 24 746 C2 ist eine Umstelleinrichtung für die Schwingwelle - Greifersystem bekannt. Gemäß dieser Druckschrift ist auf der Schwingwelle - Greifersystem ein Ritzel verdrehfest axial verschiebbar gelagert. Durch die axiale Verschiebung des Ritzels ist dieses mit einem Antriebszahnrad in der Betriebsart Schön- und Widerdruck in bzw. in der Betriebsart Schöndruck außer Eingriff bringbar, so dass die Schwingwelle - Greifersystem im Schön- und Widerdruck rotativ drehbeweglich bewegt und im Schöndruck rotativ fest steht.From DE 43 24 746 C2, a changeover device for the oscillating shaft - gripper system is known. According to this publication, a pinion is rotatably mounted axially displaceable on the oscillating shaft - gripper system. Due to the axial displacement of the pinion of this is with a drive gear in the operating mode perfecting in or in the mode Perfecting disengaged, so that the oscillating shaft - gripper system rotatably rotatably moves in perfecting pressure and rotatively fixed in Perfecting.

Die axiale Verschiebung des Ritzels wird eingeleitet über einen Pneumatikzylinder, der über eine Schaltstange, einer Kupplung und ein Verschiebestück das Ritzel auf der Schaltstange betätigt. Nachteilig hieran ist, dass die erreichte Position bei axialer Bewegung der Verstellelemente zwangsweise gesichert werden muss. Dies kann beispielsweise durch eine ständige Beaufschlagung des Pneumatikzylinders erfolgen.
Außerdem weist diese Einrichtung ein zusätzliches Sperrgetriebe für die ossizierende Bewegung der Schwingwellen im Schöndruck auf. Das Sperretriebe wird angetrieben über einen weiteren Pneumatikzylinder.The axial displacement of the pinion is initiated via a pneumatic cylinder which actuates the pinion on the shift rod via a shift rod, a clutch and a sliding piece. The disadvantage of this is that the reached position must be forcibly secured during axial movement of the adjusting elements. This can be done for example by a constant admission of the pneumatic cylinder.
In addition, this device has an additional locking gear for the ossizierende movement of the oscillating waves in Perfecting. The blocking gear is driven by a further pneumatic cylinder.

Ausgehend von diesem Stand der Technik ist es Aufgabe der Erfindung, eine Einrichtung zum Umstellen eines Greifersystems zu schaffen, die einen einfachen Aufbau und eine sichere Funktion aufweist und die Endlagen des Greifersystems selbsttätig sichert.Based on this prior art, it is an object of the invention to provide a device for switching a gripper system, which has a simple structure and a reliable function and automatically secures the end positions of the gripper system.

Erfindungsgemäß wird diese Aufgabe durch die Merkmale des 1. Anspruchs gelöst.According to the invention, this object is achieved by the features of the first claim.

Vorteil der Erfindung ist, dass die Schalt- bzw. Sperrfunktion der Greiferschwingwelle von einem Stellzylinder aus erfolgt. Der Stellzylinder wirkt gleichzeitig auf das Schalt- und Sperrgetriebe. Das Schaltgetriebe wird über den Stellzylinder, die Schaltgabel und der Rolle der Schaltgabel betätigt, wobei die Rolle in der Kurvenbahn läuft. Diese Elemente wirken senkrecht zur Schaltrichtung, so dass keine Rückstellkräfte aus dem Antrieb des Sperrgetriebes auf das Sperrgetriebe wirken. Die Schaltposition ist selbsthemmend.
Eine symmetrische Krafteinwirkung wird durch die Schaltgabel gewährleistet, deren Rollen um 180° versetzt in zwei parallen Kurvenbahnen der Schaltkurve laufen.Advantage of the invention is that the switching or blocking function of the gripper oscillation shaft is carried out by a control cylinder. The actuating cylinder acts simultaneously on the shift and lock gear. The manual transmission is operated via the actuating cylinder, the shift fork and the role of the shift fork, wherein the roller runs in the curved path. These elements act perpendicular to the switching direction, so that no restoring forces from the drive of the lock gear act on the lock gear. The switching position is self-locking.
A symmetrical force is ensured by the shift fork, whose rollers run offset by 180 ° in two parallel cam tracks of the switching cam.

Anhand eines Ausführungsbeispieles soll nachfolgend die Erfindung näher beschrieben werden.Reference to an embodiment, the invention will be described in more detail below.

On the gripper shaft 8 firmly sits the gripper tongue 10, of which over the width of the gripper shaft 8 more are provided. The drive of the gripper shaft 8 and thus the gripper tongue 10 is not shown. The gripper tongue 11 corresponding to the gripper tongue 10 is fixedly assigned to the gripper oscillation shaft 5.
On the gripper rocker shaft 5, a switching cam 12 is further mounted with an annular groove 13 axially displaceable. The switching cam 12 has two parallel curved paths offset by 180 degrees. The annular groove 13 is associated with a shift rod 14 which is axially displaceable in a longitudinal groove 38 and engages with its other end in a shift pinion 15 which is mounted axially displaceably on the gripper shaft 5. With its teeth, the shift pinion 15 engages in a toothed roller lever 16, the cam roller 17 is associated with a control cam 18 which is fixedly arranged on the side wall 3. The switching pinion 15 is rotatably mounted on the gripper rocker shaft 5 by a feather key 37.

Der Rollenhebel 16 ist drehbar in der Seitenscheibe 4 gelagert und durch eine Drehstabfeder 19 federbelastet. Fest an der Achse 2 sind weiterhin ein Stellzylinder 20 und ein Lagerbock 21 gelagert. An der Kolbenstange 22 des Stellzylinders 20 ist eine 12 Schaltgabel 23 angeordnet. Am Ende der Schaltgabel 23 ist eine Rolle 24 vorgesehen, die in der Kurvenbahn 25 der Schaltkurve12 läuft. An der Schaltkurve 12 ist weiterhin eine Drehsicherung 26 angeordnet, die mit einem festen Anschlag 36 an der Seitenscheibe 4 in Eingriff bringbar ist.The roller lever 16 is rotatably supported in the side plate 4 and spring-loaded by a torsion bar spring 19. Fixed to the axis 2, a control cylinder 20 and a bearing block 21 are also stored. On the piston rod 22 of the adjusting cylinder 20, a 12 shift fork 23 is arranged. At the end of the shift fork 23, a roller 24 is provided, which runs in the curved path 25 of the Schaltkurve12. At the switching cam 12, a rotation lock 26 is further arranged, which is engageable with a fixed stop 36 on the side window 4 in engagement.

Im Ausführungsbeispiel ist der Stellzylinder 20 als Pneumatikzylinder ausgebildet, der über die Pneumatikleitung 35 beaufschlagt wird. Es ist jedoch auch möglich, an dieser Stelle einen hydraulisch beaufschlagbaren Stellzylinder 20 vorzusehen.
Gelenkig mit der Schaltgabel 23 ist ein Schaltbolzen 27 verbunden (sh. Fig. 2 und Fig. 3), der mit seinem anderen Ende in eine Koppel 28 eingreift, die wiederum drehbeweglich über einen zweiten Schaltbolzen 29 mit einer Sperrklinke 30 verbunden ist. Die Sperrklinke 30 ist schwenkbar am Lagerbock 21 gelagert. Am anderen Ende der Sperrklinke 30 ist eine Sperrrolle 33 vorgesehen, die einem Sperrhebel 34 zugeordnet werden kann. Der Sperrhebel 34 ist fest auf der Greiferschwingwelle 5 angeordnet.
Die Schaltkurve 12, die Schaltstange 14 und das Schaltritzel 15 bilden ein Schaltgetriebe 12, 14, 15, das über den Stellzylinder 20, die Schaltgabel 23 und die Rolle 24 betätigt wird.
Die Sperrklinke 30, die Sperrrolle 33 und der Sperrhebel 34 bilden ein Sperrgetriebe 30, 33, 34, das über den Stellzylinder 20, die Schaltgabel 23 und über die Schaltbolzen 27, 29 und die Koppel 28 betätigt wird.
In den Zeichnungen sind Stellungen gleicher Elemente im Schöndruck mit S und im Schön- und Widerdruck mit SW bezeichnet.In the exemplary embodiment, the actuating cylinder 20 is designed as a pneumatic cylinder, which is acted upon via the pneumatic line 35. However, it is also possible to provide a hydraulically actuable actuating cylinder 20 at this point.
Articulated with the shift fork 23 is a shift pin 27 is connected (see Fig. 2 and Fig. 3), which engages with its other end in a coupling 28, which in turn is rotatably connected via a second shift pin 29 with a pawl 30. The pawl 30 is pivotally mounted on the bearing block 21. At the other end of the pawl 30, a locking roller 33 is provided, which can be assigned to a locking lever 34. The locking lever 34 is fixedly arranged on the gripper rocker shaft 5.
The shift cam 12, the shift rod 14 and the shift pinion 15 form a transmission 12, 14, 15, which is actuated via the actuating cylinder 20, the shift fork 23 and the roller 24.
The pawl 30, the locking roller 33 and the locking lever 34 form a locking gear 30, 33, 34, which is actuated via the actuating cylinder 20, the shift fork 23 and the shift pin 27, 29 and the coupling 28.
In the drawings, positions of the same elements in straight printing with S and in perfecting with SW are designated.

Die Wirkungsweise der Umstelleinrichtung ist folgende:The mode of operation of the changeover device is the following:

Im Schöndruck ist die Kolbenstange 22 des Stellzylinders 20 eingefahren, die Rolle 24 liegt am unteren Ende der Kurvenbahn 25. Über die Schaltkurve 12 und die in der Längsnut 38 gleitende Schaltstange 14 wurde das Schaltritzel 15 außer Eingriff mit dem verzahnten Rollenhebel 16 gebracht. Damit ist der Antrieb für eine Schwingbewegung der Greiferschwingwelle 5 wirkungslos.In fair play, the piston rod 22 of the actuating cylinder 20 is retracted, the roller 24 is located at the lower end of the cam track 25 via the switching cam 12 and sliding in the longitudinal groove 38 shift rod 14, the shift pinion 15 was disengaged from the toothed roller lever 16. Thus, the drive for a swinging movement of the gripper rocker shaft 5 is ineffective.

Die Sperrrolle 33 der Sperrklinke 30 liegt am Sperrhebel 34 an. Dadurch ist die Greiferschwingwelle 5 gesperrt.
Soll nunmehr die Druckmaschine im Schön- und Widerdruck betrieben werden, wird der Stellzylinder 20 angesteuert, die Schaltgabel 23 mit der Rolle 24 bewegt sich nach oben, wobei die Rollen 24 in der Kurvenbahn 25 der Schaltkurve 12 laufen und die Schaltkurve 12 (Fig.2) nach links verschieben. Mit der Schaltkurve 12 wird über die Schaltstange 14 das Schaltritzel 15 in Eingriff mit dem verzahnten Rollenhebel 16 gebracht, so dass die Greiferschwingwelle 5 entsprechend dem Kurvengesetz der Steuerkurve 18 oszillierend bewegt werden kann. Die Schaltgabel 23 befindet sich dabei in der in Fig. 3 als Volllinie eingezeichneten Position.
Mit dem Ausfahren der Schaltgabel 23 in die als Volllinie eingezeichnete Position wurde gleichzeitig über den Schaltbolzen 27 die Koppel 28 bewegt, die ihrerseits über den zweiten Schaltbolzen 29 die Sperrklinke 30 im Lagerbock 21 schwenkt, so dass die Sperrrolle 33 außer Kontakt mit dem Sperrhebel 34 gelangt.
Damit ist die Greiferschwingwelle 5 entriegelt und kann oszilierend bewegt werden.The locking roller 33 of the pawl 30 abuts the locking lever 34. As a result, the gripper oscillation shaft 5 is locked.
If now the printing press to be operated in perfecting, the actuating cylinder 20 is driven, the shift fork 23 with the roller 24 moves upward, the rollers 24 in the cam track 25 of the cam 12 run and the switching cam 12 (Fig ) move to the left. With the shift cam 12, the shift pinion 15 is brought into engagement with the toothed roller lever 16 via the shift rod 14 so that the gripper shaft 5 can be moved in an oscillating manner in accordance with the curve law of the control cam 18. The shift fork 23 is located in the position shown in FIG. 3 as a solid line position.
With the extension of the shift fork 23 in the drawn as a solid line position the coupling 28 was simultaneously moved via the shift pin 27, which in turn pivots on the second shift pin 29, the pawl 30 in the bearing block 21, so that the locking roller 33 comes out of contact with the locking lever 34 ,
Thus, the gripper shaft 5 is unlocked and can be moved oszilierend.

Die Schaltkurve 12 ist durch den Anschlag 36 an der Seitenscheibe 4 und der Drehsicherung 26 während des Maschinenlaufes im Schöndruck und Schön - und Widerdruck gegenüber der Wendetrommel 1 verdrehgesichert.The switching cam 12 is secured against rotation by the stop 36 on the side window 4 and the rotation lock 26 during the machine run in straight printing and perfecting with respect to the turning drum 1.
