Description

Die Erfindung betrifft eine Greifervorrichtung zum Transport von Bogen an einer Bogenkante in einer Druckmaschine mit mehreren Greifern und zwischen den Greifern vorgesehenen Zwischenräumen, in die Gegengreifer bei der Zuführung und Abnahme der Bogen eintauchen, wobei in den Zwischenräumen bewegliche Bogenauflagen angeordnet sind, die in einem Bewegungsbereich der Greifervorrichtung, in dem die Zwischenräume von den Gegengreifern freigegeben sind, in die Greiferebene bewegbar sind.The invention relates to a gripper device for transport of sheets on a sheet edge in a printing press provided with several grippers and between the grippers Spaces in the counter-grippers during feeding Immerse and remove the bow, taking in the gaps movable sheet supports are arranged in one Range of movement of the gripper device in which the gaps are released by the opponents in the Gripper level are movable.

Bei einer aus der DE 34 45 886 C2 bekannten Greifervorrichtung der angegebenen Art sind in den Zwischenräumen zwischen den Greifern als Sauggreifer ausgebildete Zusatzgreifer angeordnet, die eine mit Saugöffnungen versehene Bogenauflage haben. Zur Bewegung der Zusatzgreifer in die Greiferebene und aus ihr heraus ist in dem mit der Greifervorrichtung ausgerüsteten Zylinder eine Steuerwelle gelagert, die über Hebel und Nocken mit den Zusatzgreifern in Wirkverbindung steht und in Abhängigkeit von einer am Maschinenständer angeordneten Steuerkurve im Maschinentakt eine Schaltbewegung zum Ein- oder Ausfahren der Zusatzgreifer ausführt. Diese bekannte Vorrichtung zum Antrieb der Zusatzgreifer erfordert einen vergleichsweise hohen Bau- und Wartungsaufwand. In a gripper device known from DE 34 45 886 C2 of the specified type are in the spaces between the grippers designed as suction grippers arranged, the sheet support provided with suction openings to have. For moving the additional grippers into the gripper level and out of it is the one with the gripper device equipped cylinder, a control shaft is mounted, which are operatively connected to the additional grippers via levers and cams stands and depending on one on the machine stand arranged control curve in machine cycle one Switching movement for retracting or extending the additional grippers executes. This known device for driving the Additional gripper requires a comparatively high construction and Maintenance effort.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung der eingangs genannten Art zu schaffen, die sich durch einen geringen Bauaufwand auszeichnet.The invention has for its object a device of the type mentioned at the outset, which is characterized by distinguishes a low construction effort.

Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß die beweglichen Bogenauflagen durch die in die Zwischenräume eintauchenden Gegengreifer aus der Greiferebene und dem Bewegungsbereich der Gegengreifer herausbewegbar sind.The object is achieved in that the movable sheet supports through the in the gaps immersing counter-gripper from the gripper level and the Movement range of the counter-grippers can be moved out.

Die erfindungsgemäße Greifervorrichtung hat den Vorteil, daß zum Bewegen der beweglichen Bogenauflagen keine zusätzliche Antriebseinrichtung erforderlich ist, sondern hierzu das Eintauchen der Gegengreifer in die Zwischenräume bei der Bogenübergabe genutzt wird. Der Bauaufwand für die Anordnung beweglicher Greiferauflagen in den Zwischenräumen der Greifervorrichtung kann daher im Vergleich zu der bekannten Lösung erheblich verringert werden. Infolge des geringeren Bauaufwands ist die Anwendung beweglicher Greiferauflagen auch dann wirtschaftlich, wenn diese nicht Bestandteil eines Zusatzgreifers sind, sondern lediglich als zusätzliche Auflage für den Bogenrand im Bereich der Zwischenräume zwischen den feststehenden Greiferauflagen dient, um Eckenumknicken und Faltenbildung zu vermeiden.The gripper device according to the invention has the advantage that no additional for moving the movable sheet supports Drive device is required, but for this the immersion of the counter-grippers in the spaces the sheet transfer is used. The construction work for the Arrangement of movable gripper pads in the spaces the gripper device can therefore be compared to the known solution can be significantly reduced. As a result of The use of movable gripper pads is less expensive even economically, if not Are part of an additional gripper, but only as an additional support for the sheet edge in the area of Gaps between the fixed gripper pads serves to avoid corner twisting and wrinkling.

Zur Übertragung der Bewegung von den Gegengreifern auf die beweglichen Bogenauflagen kann erfindungsgemäß vorgesehen sein, daß die beweglichen Bogenauflagen auf der dem Bogen abgekehrten Seite einen feststehenden, in die Bewegungsbahn des Greiferfingers des Gegengreifers hineinragenden Nocken haben. Hierbei ist es vorteilhaft, wenn die beweglichen Bogenauflagen in einer im wesentlichen senkrecht zur Greiferebene ausgerichteten Geradführung geführt und mit Hilfe von Federn in die Greiferebene bewegbar sind. Weiterhin kann vorgesehen sein, daß die Lage der beweglichen Bogenauflagen in der Greiferebene durch einstellbare Anschläge festlegbar ist. Die beweglichen Bogenauflagen können sich nur über einen Teil oder über die gesamte Breite der Zwischenräume erstrecken. Weiterhin können die beweglichen Bogenauflage auch als Sauggreifer ausgebildet sein, um die Belastung der Bogenvorderkante zu verringern. Hierbei ist es allerdings erforderlich, die Saugwirkung der Sauggreifer mit Hilfe einer geeigneten Steuerung jeweils vor dem Herausbewegen der Sauggreifer aus der Greiferebene abzuschalten.To transfer the movement from the opponents to the movable sheet supports can be provided according to the invention be that the movable sheet supports on the the sheet opposite side a fixed, in the trajectory of the gripper finger of the opposing gripper protruding cam to have. It is advantageous if the movable Sheet supports in a substantially perpendicular to the gripper plane aligned straight guide and with the help are movable into the gripper plane by springs. Farther can be provided that the position of the movable sheet supports adjustable stops in the gripper plane is definable. The movable sheet supports can only over part or over the entire width of the gaps extend. Furthermore, the movable Sheet support can also be designed as a suction pad to the Reduce stress on the leading edge of the sheet. Here is however, it requires the suction of the suction pads with the help of a suitable control before moving out switch off the suction pad from the grab level.

Den Greiferauflagen 6 sind auf einer Greiferwelle 7 angeordnete Greifer 8 zugeordnet. In der geschlossenen Greiferstellung drücken die Greifer 8 mit ihren Greiferfingern 9 den Rand des Bogens 3 fest gegen die Greiferauflage 6.Figure 1 shows the gripper devices of two sheet guide cylinders 1, 2, for example an arch 3 feeding transfer cylinder and one of the sheet 3 decreasing Impression cylinder, at the time of sheet delivery. The Sheet guiding cylinder 2 has one in the axial direction extending gripper bar 4, which through a plurality Interspaces 5 gripper pads 6 separated from each other forms. The gripper pads 6 are on a gripper shaft 7 arranged gripper 8 assigned. In the closed Gripper position press the grippers 8 with their gripper fingers 9 the edge of the sheet 3 firmly against the gripper pad 6.

In den Zwischenräumen 5 der Greiferleiste 4 sind in radialer Richtung bewegliche Bogenauflagen 10 mit einer Anlagefläche 11 angeordnet. Die Bogenauflagen 10 sind jeweils an einem Zapfen 12 befestigt, der in einer Bohrung 13 der Greiferleiste 4 längsbeweglich gelagert ist. In der Bohrung 13 ist auf einem dünneren Abschnitt 14 des Zapfens 12 eine Anschlagscheibe 15 und eine Druckfeder 16 angeordnet, die sich an der Anschlagscheibe 15 und einer in der Bohrung 13 befestigten Hülse 17 abstützt. Durch die Druckfeder 16 kann der Zapfen 12 und mit ihm die Bogenauflage 10 in eine ausgefahrene Stellung bewegt werden, in der die Anlagefläche 11 in einer mit den Greiferauflagen 6 gemeinsamen Ebene liegt. Diese Stellung wird durch einen einstellbaren Anschlag 18 am radial inneren Ende des Zapfens 12 bestimmt, der auf der der Druckfeder 16 abgekehrten Seite an der Hülse 17 anschlägt. Auf der der Greiferwelle zugekehrten Seite hat die Bogenauflage 10 einen aus dem Zwischenraum 5 herausragenden Nocken 19 mit einer Führungsfläche für den Gegengreifer.In the spaces 5 of the gripper bar 4 are radial Towards movable sheet supports 10 with a contact surface 11 arranged. The sheet supports 10 are each on attached a pin 12 which in a bore 13 of the Gripper bar 4 is mounted for longitudinal movement. In the hole 13 is on a thinner portion 14 of the pin 12 Stop disc 15 and a compression spring 16 are arranged itself on the stop disc 15 and one in the bore 13 attached sleeve 17 supports.

Die Greiferauflagen 21 und die Greifer 23 sind gegenüber den Greiferauflagen 6 und den Greifern 8 in axialer Richtung versetzt angeordnet, so daß sich die Greiferauflagen 21 und die Greifer 23 jeweils in der Mitte der Zwischenräume 5 befinden.A gripper bar 20 is located on the sheet guiding cylinder 1 attached with gripper pads 21 separated by spaces, those attached to a gripper shaft 22 23 are assigned with gripper fingers 24. The gripper pads 21 and the grippers 23 are opposite the gripper pads 6 and the grippers 8 arranged offset in the axial direction, so that the gripper pads 21 and the gripper 23 are located in the middle of the gaps 5.

Bei der in Figur 1 gezeigten Bogenübergabe tauchen die Greifer 23 mit ihren Greiferfingern 24 in die Zwischenräume 5 der Greiferleiste 4 ein. Hierbei gelangen die Greiferfinger 24 in Kontakt mit den Nocken 19 der Bogenauflage 10 und verdrängen dadurch die Bogenauflage 10 gegen den Widerstand der Druckfedern 16 radial nach innen. Nach dem Schließen der Greifer 8 öffnen die Greifer 23 und fahren mit ihren Greiferfingern 24 aus den Zwischenräumen 5 heraus, wobei sie zunächst an den Nocken 19 entlanggleiten und dann von den Nocken 19 vollständig abheben. Hierbei werden die Bogenauflagen 10 von den Druckfedern 16 wieder radial nach außen in die Anschlagposition bewegt, in der ihre Anlagefläche 11 in der Greiferebene liegt und den Bogen 3 abstützt. Bei der Abnahme des Bogens 3 von dem Bogenführungszylinder 2 wiederholt sich der beschriebene Vorgang im Zusammenwirken mit den Greifern des abnehmenden Transferzylinders in analoger Weise.In the sheet transfer shown in Figure 1, the Gripper 23 with its gripper fingers 24 in the spaces 5 of the gripper bar 4. Here the gripper fingers reach 24 in contact with the cams 19 of the sheet support 10 and thereby displace the sheet support 10 against the resistance the compression springs 16 radially inwards. After closing the gripper 8 open the gripper 23 and drive with it Gripper fingers 24 out of the spaces 5, wherein they first slide along the cam 19 and then from lift cam 19 off completely. Here, the Sheet supports 10 radially from the compression springs 16 again moved to the outside in the stop position in which their contact surface 11 lies in the gripper plane and the sheet 3 supports. When removing the sheet 3 from the sheet guide cylinder 2 the process described is repeated in Interaction with the grippers of the decreasing transfer cylinder in an analogous way.

Durch die ausgefahrenen Bogenauflagen 10 wird der Rand des Bogens 3 bis zur Übergabe an die abnehmenden Greifer in den Zwischenräumen 5 gestützt und in seiner Planlage stabilisiert. Eine Faltenbildung und das Umknicken überstehender Formate wird vermieden.By the extended sheet supports 10, the edge of the Sheet 3 until it is handed over to the decreasing gripper in the Spaces 5 supported and stabilized in its flat position. A wrinkle formation and the buckling protruding Formats are avoided.
