Abstract

The invention relates to such a device, in which an eccentric shaft is provided which is mounted in a rotatable manner in the side frame of the machine and accommodates in a rotatable manner a pre-gripper shaft, which is under the influence of a cam, the eccentric shaft being firmly attached to a gearwheel which is in constant engagement with a drive gearwheel rotating with the printing cylinder. <??>In order to provide, in a device of the described nature, interlocking and consequently co-operating drive parts and a co-axial arrangement of the drive shafts and driven shafts to introduce the additional movement, which is superimposed upon the continuous rotation of the pre-gripper cam as it lifts out, the eccentric shaft (14) is rotatably mounted in a housing shell (15) on the side frame (5) and in the opposite side-frame of the machine. The pre-gripper shaft (16) is under the influence of triple cam discs (9, 10, 11), attached to the side frame (5) of the machine, via cam followers (6, 7, 8), which are attached to a connecting rod (3), which bears in a rotatable manner on the gripper shaft (16). At a hinge point (17) on the connecting rod (3) is articulated a trailing lever (4), which is articulated at a further hinge point (18), eccentric in a gearwheel (19). <IMAGE>

Description

Die Erfindung betrifft eine Vorrichtung zum Antrieb eines schwingenden Vorgreifers einer Druckmaschine nach dem Oberbegriff des ersten Patentanspruches.The invention relates to a device for driving a vibrating pre-gripper of a printing press according to the preamble of the first claim.

Derartige Vorrichtungen sind allgemein bekannt und z.B. in der DE-PS 2 220 343 beschrieben. Nachteilig ist, daß zur Steuerung der Bewegung der Vorgreiferwelle kraftschlüssig zusammenwirkende Antriebsteile vorgesehen sind. Während des Betriebes wird ein Hebelarm über eine Kurvensteuerung mittels einer Feder ständig gegen eine Rolle angepreßt. Die an dem Kraftschluß beteiligten Bauelemente werden durch die infolge der hohen Winkelgeschwindigkeiten und Beschleunigungen des Vorgreifers hervorgerufenen großen Massenkräfte zwangsweise sehr stark belastet. Von Nachteil ist ferner, daß zur Steuerung der Bewegung der Vorgreiferwelle An- und Abtriebswellen verwendet werden, deren Mittelachsen weit auseinander liegend angeordnet sind, wodurch ebenfalls große Getriebegliedlängen und daraus resultierend auch hohe Massenkräfte entstehen. Letzteres trifft auch auf einen kurventriebfreien Antrieb eines schwingenden Vorgreifers zu, wie er aus der EP-A 0 006 402 bekannt geworden ist. Außerdem ist bei derartigen Vorrichtungen keine komplette Vormontage des Vorgreifers möglich. Ebenso werden Endmontage und die Austauschbarkeit erschwert.Such devices are well known and e.g. described in DE-PS 2 220 343. The disadvantage is that to control the movement of the pre-gripper shaft non-positively interacting drive parts are provided. During operation, a lever arm is constantly pressed against a roller via a cam control by means of a spring. The components involved in the adhesion are inevitably very heavily stressed by the large inertial forces caused by the high angular velocities and accelerations of the pre-gripper. A further disadvantage is that drive and output shafts are used to control the movement of the pre-gripper shaft, the central axes of which are arranged far apart, which likewise results in large transmission link lengths and, as a result, also high inertial forces. The latter also applies to a drive of a vibrating pre-gripper that is free of cam drives, as has become known from EP-A 0 006 402. In addition, complete pre-assembly of the pre-gripper is not possible with such devices. Final assembly and interchangeability are also made more difficult.

Der Erfindung liegt die Aufgabe zugrunde, bei einer Vorrichtung genannter Gattung formschlüssig zusammenwirkende Antriebsteile und eine koaxiale Anordnung der An- und Abtriebswelle zur Einleitung der Zusatzbewegung, welche der fortlaufenden Drehbewegung des aushebenden Vorgreiferexzenters überlagert wird, vorzusehen.The invention has for its object to provide in a device of the type mentioned positively interacting drive parts and a coaxial arrangement of the input and output shaft for initiating the additional movement, which is superimposed on the continuous rotary movement of the excavating eccentric eccentric.

Gelöst wird diese Aufgabe gemäß dem Kennzeichen des ersten Patentanspruches. Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen, aus der Zeichnung und der Beschreibung. Der Vorteil der Erfindung besteht insbesondere darin, daß die Massenkräfte minimiert werden. Zugleich wird die Vormontage, die Endmontage sowie die Austauschbarkeit der Vorrichtung verbessert.This object is achieved according to the characterizing part of the first claim. Further developments of the invention result from the subclaims, from the drawing and from the description. The advantage of the invention is in particular that the mass forces are minimized. At the same time, pre-assembly, final assembly and interchangeability of the device are improved.

Die Erfindung soll nachstehend anhand von in der Zeichnung dargestellten Ausführungsbeispielen näher erläutert werden.The invention will be explained below with reference to exemplary embodiments shown in the drawing.

Fig. 1 zeigt das kinematische Schema einer viergliedrigen kinematischen Kette, bestehend aus Antriebsglied 1, Vorgreiferebene 2, Steuerkoppel 3 und Schlepphebel 4, welche die geforderte Bewegung 24 der Vorgreiferebene 2 dadurch erzeugen, daß das im Seitenständer 5 gelagerte Antriebsglied 1 mit konstanter Winkelgeschwindigkeit angetrieben wird und der Schlepphebel 4 die auf der Steuerkoppel 3 angeordneten Kurvenrollen 6, 7, 8 über ein Tripel im Ständer 5 fest verschraubter, zugeordneter Kurvenscheiben 9, 10, 11 zieht. Die Kurvenscheiben 9, 10, 11 sind derart gestaltet, daß die geforderte Bewegung 24 der Vorgreiferebene 2 erreicht wird.Fig. 1 shows the kinematic diagram of a four-link kinematic chain, consisting of drive link 1, pre-gripper level 2, control coupling 3 and rocker arm 4, which generate the required movement 24 of the pre-gripper level 2 by driving the drive link 1 mounted in the side stand 5 at a constant angular velocity and the rocker arm 4 pulls the cam rollers 6, 7, 8 arranged on the control coupling 3 via a triple screw in the stand 5, assigned cam plates 9, 10, 11. The cams 9, 10, 11 are designed such that the required movement 24 of the pre-gripper level 2 is achieved.

Die Figuren 2 bis 4 zeigen verschiedene konstruktive Ausführungen, welche sich durch die Anordnung des Kurvenscheiben 26, 27 und einer innenberollten Kurvenscheibentripels unterscheiden. Fig. 2 und 4 zeigen eine mögliche Ausführung mit drei außenberollten Kurvenscheiben 9, 10, 11 und Fig. 3 zeigt eine Ausführung mit zwei außenberollten Kurvenscheiben 26, 27 und einer innenberollten Kurvenscheibe 12. Die zweite Ausführung hat den Vorteil einer geringeren Bauhöhe. Zur Vereinfachung sind gleiche Bauteile in den beiden Ausführungen mit gleichen Bezugszeichen versehen.FIGS. 2 to 4 show different designs, which differ in the arrangement of the cam disks 26, 27 and an internally rolled cam disk triple. 2 and 4 show a possible embodiment with three externally rolled cam disks 9, 10, 11 and FIG. 3 shows an embodiment with two externally rolled cam disks 26, 27 and an internally rolled cam disk 12. The second embodiment has the advantage of a smaller overall height. To simplify matters, the same components are provided with the same reference symbols in the two versions.

Bei beiden konstruktiven Ausführungen ist auf eine Exzenterwelle 14, die drehbar in einer Gehäuseschale 15 am Seitenständer 5 gelagert ist, eine Vorgreiferwelle 16 drehbar gelagert. Auf einem Lagerkörper 13, der fest mit der Vorgreiferwelle 16 verbunden ist. ist auf 15 Wälzkörpern 25 die Steuerkoppel 3 drehbeweglich angeordnet. Diese ist im Gelenkpunkt 17 mit dem relativ kurzen Schlepphebel 4 verbunden, der im Gelenkpunkt 18 in einem Zahnrad 19 außermittig angelenkt ist. Zahnrad 19 und Exzenterwelle 14 bilden das Antriebsglied 1, wobei deren Mittelachsen koaxial zueinander liegen.In both structural designs, a pre-gripper shaft 16 is rotatably mounted on an eccentric shaft 14, which is rotatably mounted in a housing shell 15 on the side stand 5. On a bearing body 13 which is fixedly connected to the pre-gripper shaft 16. the control coupling 3 is rotatably arranged on 15 rolling elements 25. This is connected at the articulation point 17 to the relatively short rocker arm 4, which is articulated off-center in a gear 19 at the articulation point 18. Gear 19 and eccentric shaft 14 form the drive member 1, the central axes of which are coaxial with one another.

Das Zahnrad 19 steht im ständigen Eingriff mit einem mit dem Druckzylinder 20 umlaufenden Antriebsrad 21.The gear wheel 19 is in constant engagement with a drive wheel 21 rotating with the pressure cylinder 20.

Die Steuerung der Bewegung 24 der Vorgreiferwelle 16 erfolgt durch die Überlagerung einer Kreisbewegung - wobei der Radius der Kreisbahn durch die Größe der Exzentrizität, d.h. der Entfernung der Mittelachse des Zahnrades 19 von der Mittelachse der Vorgreiferwelle 16 bestimmt ist - mit einer über das feststehende Kurvenscheibentripel 9, 10, 11 bzw. 12, 26, 27 gesteuerten allgemeinen Koppelbewegung, wodurch der Vorgreiferwelle 16 als Zusatzbewegung eine Schwenkbewegung mitgeteilt wird. Die geforderte Bewegung 24 der Vorgreiferwelle 16 ist in Fig. 1 als Bewegung der Vorgreiferebene 2 gestrichelt dargestellt. Der zeitliche Ablauf gewährleistet eine Ruhelage der Greifer 22 bei der Übergabe des Bogens vom Anlagetisch 23, eine Übergabe des Bogens an die nicht dargestellten Greifer des Druckzylinders 20 bei gleicher Geschwindigkeit und eine Beendigung der Rückbewegung, bei der die Greifer 22 vom Druckzylinder 20 bis in die Ruhelage entfernt und unter allmählicher Annäherung wieder in die Ausgangslage für die Übernahme eines neuen Bogens zurückgeführt werden.The movement 24 of the pre-gripper shaft 16 is controlled by superimposing a circular movement - the radius of the circular path being determined by the size of the eccentricity, ie the distance of the central axis of the toothed wheel 19 from the central axis of the pre-gripper shaft 16 - by one over the fixed one Cam triple 9, 10, 11 or 12, 26, 27 controlled general coupling movement, whereby the pre-gripper shaft 16 is informed of a pivoting movement as an additional movement. The required movement 24 of the pre-gripper shaft 16 is shown in dashed lines in FIG. 1 as the movement of the pre-gripper plane 2. The chronological sequence ensures that the grippers 22 are at rest when the sheet is transferred from the feed table 23, the sheet is transferred to the grippers of the printing cylinder 20 (not shown) at the same speed and an end of the return movement, in which the grippers 22 extend from the printing cylinder 20 into the Rest position removed and returned gradually to the starting position for the takeover of a new arch.
