This curve has a grip closing region (24) and a grip opening region (26). The closing region has an auxiliary opening region (28). This auxiliary opening region is designed to compensate for an auxiliary closing region (29) on the one-revolution running curve (18). The auxiliary opening region may have an opening cam and the auxiliary closing region may have a control recess.

Description

Die Erfindung betrifft eine Greifersteuerung für einen zyklisch schwingend angetriebenen Vorgreifer zum Einzelbogentransport in einer Bogendruckmaschine.The invention relates to a gripper control for a cyclically oscillating pre-gripper for single sheet transport in a sheet printing machine.

Durch die DE 43 30 392 A1 ist es bekannt, an einem freien Ende eines Vorgreifers wenigstens einen Bogengreifer vorzusehen, wobei der Vorgreifer einen um eine gestellfeste Schwingachse schwenkbaren Schwinghebel aufweist. Parallel zur Schwingachse ist eine Gelenkachse zum Schließen und öffnen des Bogengreifers vorgesehen. Eine eintourig umlaufende Kurve und eine ortsfest schwenkbare Kurve mit einem Rollenhebel, dessen Kurvenrolle an der ersten Kurve anliegt, verschwenken die zweite Kurve zyklisch in ihrer Lage. Hierbei bestimmen die Lagen der Kurven den öffnungs- und Schließzeitpunkt des Greifers.From DE 43 30 392 A1 it is known to provide at least one sheet gripper on a free end of a pre-gripper, the pre-gripper having an oscillating lever which can be pivoted about an oscillation axis fixed to the frame. A hinge axis for closing and opening the sheet gripper is provided parallel to the swing axis. A one-turn revolving curve and a stationary swiveling curve with a roller lever, the curve roller of which rests on the first curve, cyclically pivot the second curve in its position. The positions of the curves determine the opening and closing times of the gripper.

Bei einem Vorhandensein von fehlbogen, d. h. Schrägbogen oder Mehrfachbogen an der Bogenübernahmestelle am Anlegetisch, dürfen diese Fehlbogen nicht vom Vorgreifer transportiert und an den nachfolgenden Zylinder übergeben werden.In the presence of misfires, i.e. H. Inclined sheets or multiple sheets at the sheet transfer point on the feed table, these missing sheets must not be transported by the pre-gripper and transferred to the subsequent cylinder.

Der Erfindung liegt die Aufgabe zugrunde, eine Greifersteuerung für einen zyklisch schwingend angetriebenen Vorgreifer zum Einzelbogentransport in einer Bogendruckmaschine zu schaffen.The invention has for its object to provide a gripper control for a cyclically vibrating pre-gripper for single sheet transport in a sheet printing machine.

Die Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst.The object is achieved by the characterizing features of claim 1.

In vorteilhafter weise ist ein Schaltmechanismus in Form einer einrastbaren Klinke vorgesehen, der die Greiferöffnungs-/schließkurve in einer Greiferöffnungslage festsetzt, so daß der Greifer bei seiner schwingenden Transportbewegung geöffnet bleibt und somit keinen Bogentransport durchführt.Advantageously, a switching mechanism in the form of a snap-in pawl is provided, which fixes the gripper opening / closing curve in a gripper opening position, so that the gripper vibrates when it is open The transport movement remains open and therefore does not carry out sheet transport.

Um zu vermeiden, daß zwischen Greiferfinger und Greiferauflage ohne Schließbewegung eingeklemmte Mehrfachbögen transportiert werden, ist im Schließbereich des Kurvensegments ein zusätzlicher Greiferöffnungsbereich angeordnet. Durch diese vorteilhafte Maßnahme wird der Greifer im vorbeschriebenen Fall über das Maß, das er an der Bogenübernahmestelle am Anlegetisch aufweist geöffnet, so daß möglicherweise eingeklemmte Mehrfachbogen losgelassen werden. Damit im Normalbetrieb ein ungewolltes öffnen der Greifer im Schließbereich des zusätzlichen öffnungsbereiches unterbleibt, ist es vorgesehen, an der Steuerkontur der eintourig umlaufenden Kurve einen Greiferschließbereich zur Kompensation des zusätzlichen Greiferöffnungsbereiches des Kurvensegments vorzusehen.In order to avoid that multiple sheets clamped between gripper fingers and gripper support without closing movement are transported, an additional gripper opening area is arranged in the closing area of the curve segment. As a result of this advantageous measure, the gripper is opened in the case described above to the extent that it has at the sheet transfer point on the feed table, so that possibly jammed multiple sheets are released. So that an unintentional opening of the gripper in the closing area of the additional opening area does not occur, provision is made for a gripper closing area to be provided on the control contour of the single-revolution curve to compensate for the additional gripper opening area of the curve segment.

Die Erfindung ist in der Zeichnung dargestellt und wird im folgenden beschrieben.The invention is illustrated in the drawing and is described below.

Es zeigt die Figur eine schematische Darstellung der Greifersteuerung im Schnitt.The figure shows a schematic representation of the gripper control in section.

Ein Vorgreifergreifer 1 einer Bogendruckmaschine weist einen Greiferfinger 2 und eine Greiferauflage 3 auf und ist am Ende eines um eine Schwingachse 4 zyklisch schwingend angetriebenen Schwinghebels 6 angeordnet. Der Vorgreifergreifer 1 weist eine Gelenkachse 7, an welcher der Greiferfinger 2 befestigt ist, und einen die Gelenkachse schwenkenden Hebel 8 auf. Der Hebel 8 trägt an seinem Ende eine drehbar gelagerte Segmentrolle 9, die mit einer Steuerkontur 11 eines Kurvensegmentes 12 in Arbeitskontakt steht. Das Kurvensegment 12 ist um einen gestellfesten Schwenkpunkt 13 schwenkbar gelagert. Ein mit dem Kurvensegment 12 verbundener Rollenhebel 14 trägt an seinem freien Ende eine drehbar angeordnete Kurvenrolle 16, die mit der Steuerkontur 17 einer eintourig umlaufenden Steuerkurve 18 in Arbeitskontakt steht.A pre-gripper 1 of a sheet-fed printing machine has a gripper finger 2 and a gripper support 3 and is arranged at the end of an oscillating lever 6 which is driven to oscillate cyclically about an oscillation axis 4. The pre-gripper 1 has an articulated axis 7, to which the gripper finger 2 is fastened, and a lever 8 pivoting the articulated axis. The lever 8 carries at its end a rotatably mounted segment roller 9, which is in working contact with a control contour 11 of a curve segment 12. The curve segment 12 is pivotally mounted about a pivot point 13 fixed to the frame. A roller lever 14 connected to the cam segment 12 carries on its free end of a rotatably arranged cam roller 16, which is in working contact with the control contour 17 of a single-rotating control cam 18.

Ein zu transportierender Bogen 19 wird im Betrieb vom Vorgreifergreifer 1 am Anlegetisch 21 übernommen und an einen Greifer 22 eines nachgeordneten Zylinders 23 übergeben.During operation, a sheet 19 to be transported is taken over by the pre-gripper 1 on the feed table 21 and transferred to a gripper 22 of a downstream cylinder 23.

Eine "Geöffnet"-Stellung der Greifer 2 am Anlegetisch 21 ist hierbei dadurch erzielbar, daß die Steuerkontur 17 des Kurvensegmentes 12 gegen den Uhrzeigersinn in die "Geöffnet"-Stellung geschwenkt wird. Das Greifer-Schließen wird hierbei durch einen Schließbereich 20 der Steuerkurve 18 bestimmt. Das Kurvensegment 12 wird hierbei so weit um den Schwenkpunkt 13 ausgelenkt, daß der Greifer 2 mittels der Segmentrolle 9 und der Steuerkontur 11 geschlossen wird.An "open" position of the grippers 2 on the feed table 21 can be achieved in that the control contour 17 of the cam segment 12 is pivoted counterclockwise into the "open" position. The gripper closing is determined by a closing area 20 of the control cam 18. The curve segment 12 is deflected so far about the pivot point 13 that the gripper 2 is closed by means of the segment roller 9 and the control contour 11.

Aus dieser Position schwenkt der Vorgreifer 6 um die Schwingachse 4 in eine übergabestellung, in welcher der Bogen 19 an den Greifer 22 des nachgeordneten Zylinders 23 übergeben wird. Die Segmentrolle 9 gelangt hierbei über einen Schließbereich 24 des Kurvensegments 12 zu eine: öffnungsbereich 26 des Kurvensegments 12. Der Schließbereich 24 weist zusätzlich einen öffnungsnocken 28 auf.From this position, the pre-gripper 6 pivots about the oscillation axis 4 into a transfer position, in which the sheet 19 is transferred to the gripper 22 of the downstream cylinder 23. In this case, the segment roller 9 passes through a closing area 24 of the curve segment 12 to an: opening area 26 of the curve segment 12. The closing area 24 additionally has an opening cam 28.

Bei einem störungsfreien Bogentransport, d. h. es liegen keine Fehlbogenmeldungen vor, wird die Wirkung dieses öffnungsnockens 28 dadurch kompensiert, daß ein Steuertal 29 an der Steuerkontur 17 der Kurve 18 vorgesehen ist.With trouble-free sheet transport, i. H. there are no false sheet reports, the effect of this opening cam 28 is compensated for by the fact that a control valley 29 is provided on the control contour 17 of the curve 18.

Bei einer Fehlbogenmeldung setzt eine schwenkbar gelagerte Schaltklinke 31 das Kurvensegment 12 in einer "Geöffnet"-Stellung des Vorgreifergreifers 1 fest.In the event of a false sheet message, a pivotally mounted pawl 31 fixes the curve segment 12 in an “open” position of the gripper 1.

Durch diese Maßnahme wird der Greiferfinger 2 geöffnet gehalten und es wird verhindert, daß ein Bogentransport vorgenommen wird. Gelangt die Segmentrolle 9 in den Bereich des öffnungsnockens 28 wird der Greiferfinger 2 noch ein wenig über das Standardöffnungsmaß gegenüber der Greiferauflage 3 angehoben, d. h. ein Abstand zwischen Greiferfinger 2 und Greiferauflage 3 ist im öffnungsbereich, in welchem die Segmentrolle 9 mit dem öffnungsnocken 28 in Arbeitskontakt steht, größer als ein Abstand, den der Greiferfinger 2 gegenüber der Greiferauflage 3 in geöffnetem Zustand am Anlegetisch 21 aufweist. Durch diese Maßnahme können Mehrfachbögen, die z. B. ohne Schließbewegung des Vorgreifergreifers 1 transportiert würden, sicher losgelassen werden.This measure keeps the gripper finger 2 open and prevents sheet transport from being carried out. If the segment roller 9 reaches the area of the opening cam 28, the gripper finger 2 is raised a little above the standard opening dimension compared to the gripper pad 3, i.e. a distance between the gripper finger 2 and the gripper pad 3 is in the opening area in which the segment roller 9 is in working contact with the opening cam 28 is greater than a distance that the gripper finger 2 has at the feed table 21 in the open state relative to the gripper support 3. Through this measure, multiple sheets, the z. B. would be transported without closing movement of the pre-gripper 1 can be safely released.
