Description

Die Erfindung betrifft eine Einrichtung gemäß Oberbegriff des Patentanspruchs. Eine derartige Einrichtung ist beispielsweise aus der Druckschrift US-3.180.638 bekannt. Bei einer derartigen Einrichtung besteht in einer Phase der Vereinigung zwischen dem Restbogenstapel und dem Hauptbogenstapel ein von zu einem Rechen zusammengefaßten Gitterstäben aufrechterhaltener Spalt, der sich in der abschließenden Phase der Vereinigung unter Absenkung des Reststapels um die Höhe des Querschnitts der Gitterstäbe schließt. In Verbindung mit einem Hubmechanismus und einer diesen derart steuernden Detektoreinrichtung, daß eine Oberkante des Restbogenstapels auf ein bestimmtes Niveau eingeregelt wird, und mit einer Justiereinrichtung für den Abstand einer Bogenvereinzelungseinrichtung zu einer Oberkante des Bogenstapels sowie einer die Justiereinrichtung derart ansteuernden Detektoreinrichtung, daß der besagte Abstand auf ein bestimmtes Maß eingeregelt wird, wirkt sich die genannte Absenkung des Restbogenstapels insofern nachteilig aus, als in entsprechenden Regelstrecken eine sprunghaft auf einen relativ hohen Wert ansteigende Störgröße verarbeitet werden muß.The invention relates to a device according to the preamble of the claim. Such a device is known for example from US-3,180,638. In such a device, in a phase of the union between the remaining sheet stack and the main sheet stack, there is a gap maintained by lattice bars combined into a rake, which gap closes in the final phase of the union while lowering the remaining stack by the height of the cross section of the lattice bars. In connection with a lifting mechanism and a detector device controlling it in such a way that an upper edge of the remaining sheet stack is adjusted to a certain level, and with an adjusting device for the distance of a sheet separating device to an upper edge of the sheet stack as well as a detector device controlling the adjusting device in such a way that said distance is regulated to a certain extent, the mentioned lowering of the remaining sheet stack has a disadvantageous effect in that a disturbance variable which increases suddenly to a relatively high value must be processed in corresponding controlled systems.

Besonders nachteilig ist hierbei beim Einsatz einer gattungsgemäßen Einrichtung in Verbindung mit einem Bogenanleger einer Druckmaschine der Umstand, daß in solchen Bogenanlegern die Nachführung der genannten Bogenvereinzelungseinrichtung langsamer vonstatten geht als die Niveauregulierung des Restbogenstapels. Das Absacken des Restbogenstapels in der abschließenden Phase der Vereinigung kann bei einem solchen Einsatz somit zu Betriebsstörungen an einer Druckmaschine führen.Particularly disadvantageous when using a generic device in connection with a sheet feeder of a printing press is the fact that in such sheet feeders the tracking of said sheet separation device is slower than the level regulation of the remaining sheet stack. The sagging of the leftover sheet stack in the final phase of the merging can thus lead to malfunctions on a printing press in such an application.

Der Erfindung liegt die Aufgabe zugrunde, eine gattungsgemäße Einrichtung so auszugestalten, daß bei deren Einsatz in Verbindung mit einem Bogenanleger einer Druckmaschine an dieser keine Betriebsstörungen auftreten, die auf das Absacken des Restbogenstapels in der abschließenden Phase der Vereinigung zurückzuführen sind. Diese Aufgabe wird gelöst mit einer im Patentanspruch angegebenen Einrichtung.The invention has for its object to design a generic device so that when used in conjunction with a sheet feeder of a printing machine no malfunctions occur on this, which are due to the sagging of the remaining sheet stack in the final phase of the union. This object is achieved with a device specified in the claim.

Eine erfindungsgemäße Einrichtung hat darüber hinaus den Vorteil, daß bei ihrem Einsatz in Verbindung mit einem Bogenanleger einer Druckmaschine besagte Betriebsstörungen vermieden werden können, ohne daß Eingriffe in die dort vorgesehenen Regelstrecken vorgenommen werden müssen.A device according to the invention also has the advantage that, when used in conjunction with a sheet feeder of a printing press, said operational disturbances can be avoided without interventions in the control paths provided there.

Die Erfindung ist nachfolgend anhand von Zeichnungen eines Ausführungsbeispiels näher erläutert.The invention is explained below with reference to drawings of an embodiment.

In Fig. 1 ist eine Stapelanordnung nur schematisch mit strichpunktierten Linien angedeutet. Dabei ist ein Restbogenstapel 1 und ein Hauptbogenstapel 2 in einer Phase der Vereinigung dargestellt, in welcher der Restbogenstapel 1 mit seinem untersten Bogen auf horizontal angeordneten Gitterstäben 3 einer insgesamt mit 4 bezeichneten Verschiebeeinrichtung aufsitzt und der Hauptbogenstapel 2 mit seinem obersten Bogen von unten gegen die Gitterstäbe 3 angestellt ist, welche sich hierbei in der strichpunktiert gezeichneten, gegenüber der mit Voll-Linien gezeichneten in Längsrichtung der Gitterstäbe 3 verschobenen Lage befinden. Die über eine Seitenfläche der Stapelanordnung hinausragenden freien Enden der Gitterstäbe 3 sind in bekannter Weise mittels einer in Fig. 1 im Querschnitt erkennbaren Hilfstraverse 5 abgestützt.In Fig. 1, a stack arrangement is only indicated schematically with dash-dotted lines. A remaining sheet stack 1 and a main sheet stack 2 are shown in a phase of the union in which the remaining sheet stack 1 with its lowermost sheet is seated on horizontally arranged lattice bars 3 of a displacement device, generally designated 4, and the main sheet stack 2 with its uppermost sheet from below against the lattice bars 3 is employed, which are in the position shown in dash-dotted lines, displaced in relation to the position drawn in the longitudinal direction of the bars 3 in the longitudinal direction. The free ends of the lattice bars 3 projecting beyond a side surface of the stack arrangement are supported in a known manner by means of an auxiliary cross member 5 which can be seen in cross section in FIG. 1.

Der Hauptbogenstapel 2 sitzt mit seinem untersten Bogen auf einer Stapeltragplatte 6 auf. In einem Bogenanleger einer Druckmaschine wird ein auf einer solchen Stapeltragplatte sitzender Bogenstapel während des Fortdrucks mittels bekannter Hubmechanismen im gleichen Maße angehoben, wie die Höhe des Bogenstapels abnimmt bis er schließlich zu einem Restbogenstapel wird. Beim Einsatz der Verschiebeeinrichtung 4 in Verbindung mit einem Anleger einer Druckmaschine sitzt somit der Restbogenstapel mit seinem untersten Bogen vor der Vereinigung mit dem Hauptstapel 2 zunächst ebenfalls auf einer in Fig. 1 mit 6 bezeichneten Stapeltragplatte auf, bis diese nach einem erfolgten Unterfangen des Restbogenstapels 1 mittels der Gitterstäbe 3 in bekannter Weise unter Absenkung mittels des genannten Hubmechanismus entfernt wird. Diese Stapeltragplatte 6 ist an ihrer horizontal ausgerichteten Oberseite in an sich bekannter Weise mit untereinander parallelen Nuten 7 versehen. Eine Schar der untereinander parallelen Gitterstäbe 3 ist zu einem Rechen 8 zusammengefaßt. Dabei sind die Querschnitte der Gitterstäbe 3 und der Nuten 7 so aufeinander abgestimmt, daß die Gitterstäbe 3 in deren Längsrichtung so in die Nuten 7 einschiebbar sind, daß der Restbogenstapel 1 in einer Phase der Vereinigung von den Gitterstäben 3 unterfangen wird.The main sheet stack 2 sits with its lowest sheet on a stack support plate 6. In a sheet feeder of a printing press, a sheet stack seated on such a stack support plate is raised to the same extent as known during the production by means of known lifting mechanisms The height of the sheet stack decreases until it finally becomes a remaining sheet stack. When using the shifting device 4 in connection with a feeder of a printing machine, the bottom sheet stack with its bottom sheet before the combination with the main stack 2 is also initially seated on a stack support plate designated 6 in FIG. 1 until the bottom sheet stack 1 has been undertaken is removed by means of the bars 3 in a known manner while lowering by means of the lifting mechanism mentioned. This stack support plate 6 is provided on its horizontally oriented top in a manner known per se with mutually parallel grooves 7. A group of the parallel bars 3 is combined to form a rake 8. The cross sections of the bars 3 and the grooves 7 are coordinated so that the bars 3 can be inserted in the longitudinal direction in the grooves 7 so that the remaining sheet stack 1 is underpinned by the bars 3 in a phase of union.

Zum Verschieben der Gitterstäbe 3 in deren Längsrichtung sind hierzu in der Verschiebeeinrichtung 4 Führungsschienen 9 vorgesehen, auf welchen der Rechen 8 verschieblich in Einschubrichtung aus einer ersten in eine zweite Lage und umgekehrt entgegen der Einschubrichtung gelagert ist.To move the bars 3 in their longitudinal direction, guide rails 9 are provided in the displacement device 4, on which the rake 8 is slidably mounted in the direction of insertion from a first to a second position and vice versa against the direction of insertion.

Auf die in Fig. 1 mit Blick auf die gegenseitige Lage von Reststapel 1, Hauptstapel 2 und dazwischen eingeschlossenen Gitterstäben 3 dargestellte Phase der Vereinigung folgt in einer abschließenden Phase der Vereinigung das Herausziehen der Gitterstäbe 3 aus der dargestellten Stapelanordnung in einer in Fig. 1 nach rechts weisenden Entnahmerichtung. Um zu verhindern daß hierbei in der Nachbarschaft der Gitterstäbe 3 befindliche Bogen ebenfalls in Entnahmerichtung verschoben werden, ist eine an sich bekannte, quer zur Längsrichtung der Gitterstäbe 3 verlaufende und in Längsrichtung der Gitterstäbe 3 verschieblich angeordnete Anschlagschiene 10 mit in Fig. 4 und 5 erkennbaren Durchbrechungen 11 zum Durchtritt der Gitterstäbe 3 durch diese Anschlagschiene 10 vorgesehen.The phase of the union shown in FIG. 1 with a view to the mutual position of the remaining stack 1, the main pile 2 and the bars 3 enclosed therebetween is followed by the pulling out of the bars 3 from the stack arrangement shown in FIG. 1 in a final phase of the union right-hand removal direction. In order to prevent sheets located in the vicinity of the bars 3 from being displaced in the removal direction as well, there is a known one that runs transversely to the longitudinal direction of the bars 3 and runs in the longitudinal direction of the bars 3 slidably arranged stop rail 10 with openings 11 recognizable in FIGS. 4 and 5 for the passage of the bars 3 through this stop rail 10.

Wie aus Fig. 2 erkennbar ist mit je einer Führungsschiene 9 je ein Seitenteil und mit der Anschlagschiene 10 ein stirnseitiger Schenkel des Rahmens 12 gebildet.As can be seen from FIG. 2, a side part is formed with a guide rail 9 and a front leg of the frame 12 is formed with the stop rail 10.

Der in Fig. 3 aus der Verschiebeeinrichtung 4 herausgelöst und in einer der Lage in Fig. 2 entsprechenden Lage dargestellte Rahmen 12 ist weiterhin mittels einer ersten Ouerstrebe 13 an einem in Fig. 3 links gelegenen vorderen Ende und mittels einer zweiten Querstrebe 14 an einem in Fig. 3 rechts gelegenen hinteren Ende der Führungsschiene 9 versteift.The frame 12, which is detached from the displacement device 4 in FIG. 3 and shown in a position corresponding to the position in FIG. 2, is furthermore attached to a front end on the left in FIG Fig. 3 right rear end of the guide rail 9 stiffened.

Wie aus Fig. 6 erkennbar, ist eine jeweilige Führungsschiene 9 aus einer oberen Führungsstange 15 und aus einer unteren Führungsstange 16 zusammengesetzt. Hiervon dient die jeweils obere Führungsstange 15 als Geradführung für den Rechen 8, der in Fig. 7 aus der Verschiebeeinrichtung 4 herausgelöst und in einer der Lage in Fig. 2 entsprechenden Lage dargestellt ist. Dieser Rechen 8 ist gebildet aus einer Brücke 17, in welcher die Gitterstäbe 3, wie am deutlichsten in Fig. 8 erkennbar, an einem ihrer Enden eingespannt sind. Die Brücke 17 erstreckt sich quer zur Längsrichtung der Gitterstäbe 3 und besitzt Brückenlager in Form von Geradführungsprofilen 18, welche eine jeweilige obere Führungsstange 15 einer der Führungsschienen 9 umgreifen. Für eines der Geradführungsprofile 18 ist deren Anschluß an eine jeweilige obere Führungsstange 15 in Fig. 9 wiedergegeben, wobei die obere und die untere Führungsstange 15 und 16 jeweils strichpunktiert dargestellt ist. Die Führungsschienen 9 und die Gitterstäbe 3 verlaufen zueinander parallel, so daß der Rechen 8 gegenüber dem Rahmen 12 in Längsrichtung der Gitterstäbe 3 verschieblich gelagert ist.As can be seen from FIG. 6, a respective guide rail 9 is composed of an upper guide rod 15 and a lower guide rod 16. Of these, the respective upper guide rod 15 serves as a straight guide for the rake 8, which is detached from the displacement device 4 in FIG. 7 and is shown in a position corresponding to the position in FIG. 2. This rake 8 is formed from a bridge 17 in which the bars 3, as can be seen most clearly in FIG. 8, are clamped at one of their ends. The bridge 17 extends transversely to the longitudinal direction of the bars 3 and has bridge bearings in the form of straight guide profiles 18 which encompass a respective upper guide rod 15 of one of the guide rails 9. For one of the straight guide profiles 18, their connection to a respective upper guide rod 15 is shown in FIG. 9, the upper and lower guide rods 15 and 16 each being shown in broken lines. The guide rails 9 and the bars 3 run parallel to each other, so that the Rake 8 is displaceably mounted relative to the frame 12 in the longitudinal direction of the bars 3.

Als Antriebsmittel zur Verschiebung des Rechens 8 gegenüber dem Rahmen 12 sind zwischen der ersten und der zweiten Querstrebe 13 und 14 des Rahmens 12 parallel zu den Führungsschienen 9 orientierte Bandzylinder 19 eingesetzt, deren Bänder, wie in Fig. 10 mit strichpunktierten Linien angedeutet mit der Brücke 17 des Rechens 8 verbunden sind. In Fig. 7 sind mit 20 entsprechende schematisch dargestellte und in strichpunktierten Linien wiedergegebene Verbindungsmittel zur Verbindung der Bänder der Bandzylinder 19 mit der Brücke 17 bezeichnet.As drive means for displacing the rake 8 with respect to the frame 12, between the first and the second cross struts 13 and 14 of the frame 12 parallel belt guides 19 are used, the belts of which, as indicated in FIG. 10 with dash-dotted lines, with the bridge 17 of the rake 8 are connected. In Fig. 7 with 20 corresponding schematically shown and shown in dash-dotted lines connecting means for connecting the bands of the band cylinder 19 to the bridge 17 are designated.

Der Rahmen 12 ist seinerseits innerhalb der Verschiebeeinrichtung 4 in Längsrichtung der Gitterstäbe 3 und in der Horizontalen quer zur Längsrichtung der Gitterstäbe 3 verschiebbar gelagert. Hierzu ist die Verschiebeeinrichtung 4 mit einem Querschlitten 21 ausgestattet.The frame 12 is in turn displaceably mounted within the displacement device 4 in the longitudinal direction of the bars 3 and in the horizontal direction transversely to the longitudinal direction of the bars 3. For this purpose, the displacement device 4 is equipped with a cross slide 21.

Der in Fig. 11 aus der Verschiebeeinrichtung 4 herausgelöst und in einer der Lage in Fig. 2 entsprechenden Lage dargestellte Querschlitten 21 erstreckt sich quer zu den Gitterstäben 3 von einer Führungsschiene 9 an einer ersten Längsseite des Rahmens 12 zur gegenüberliegenden Führungsschiene 9 an einer zweiten Längsseite des Rahmens 12 und besitzt den am Rechen 8 vorgesehenen Geradführungsprofilen 18 (Fig. 9, 10) entsprechende Geradführungsprofile 22. Diese Geradführungsprofile 22 umgreifen eine jeweilige untere Führungsstange 16 einer jeweiligen Führungsschiene 9.

Der zweite Zylinder 27 ist mit seinem einen Ende am Führungskopf 28 angelenkt, während das diesem Ende abgewandte Ende der Kolbenstange des zweiten Zylinders 27 mit einer weiteren Lasche 31 gelenkig verbunden ist, die ihrerseits am Rahmen 12 befestigt ist.In the exemplary embodiment, an automatic displacement of the frame 12 relative to the cross slide 21 is provided. For this purpose, a piston-cylinder arrangement having a first cylinder 26 and a second cylinder 27 and effective between the cross slide 21 on the one hand and the frame 12 on the other hand is provided. The first cylinder 26 is flanged to a guide head 28 which is guided by means of a slideway 29 fastened to the cross slide 21 in the longitudinal direction of the lattice bars 3, while the piston rod of this first cylinder 26 is articulated to a bracket 30 fastened to the cross slide 21 (see FIG. 11, 13, 14). The second cylinder 27 is articulated at one end to the guide head 28, while the end of the piston rod of the second cylinder 27 facing away from this end is connected in an articulated manner to a further link 31, which in turn is attached to the frame 12.

Das Schlittenführungsbett 24 ist, wie in Fig. 15, 16 und 17 dargestellt, als Hubwagen ausgebildet, der entlang eines Hubgestells 32 (siehe Fig. 18) vertikal verfahrbar ist. Zum Verfahren des Hubwagens entlang des Hubgestells 32 ist das Schlittenführungsbett 24 über ein Zugmittel 35, wie beispielsweise eine Kette oder einen Zahnriemen, mit einem Hubantrieb 36 verbunden (siehe Fig. 1).As shown in FIGS. 15, 16 and 17, the slide guide bed 24 is designed as a lifting truck which can be moved vertically along a lifting frame 32 (see FIG. 18). To move the lifting truck along the lifting frame 32, the slide guide bed 24 is connected to a lifting drive 36 via a traction means 35, such as a chain or a toothed belt (see FIG. 1).

Im Ausführungsbeispiel ist weiterhin eine selbsttätige Verschiebung des Querschlittens 21 gegenüber dem Schlittenführungsbett 24 vorgesehen. Hierzu ist am Schlittenführungsbett 24 ein Linearstellantrieb 33 befestigt und eine Schubstange des Linearstellantriebs 33 an einer weiteren Lasche 34 angelenkt, die am Querschlitten 21 befestigt ist.In the exemplary embodiment, an automatic displacement of the cross slide 21 relative to the slide guide bed 24 is also provided. For this purpose, a linear actuator 33 is attached to the slide guide bed 24 and a push rod of the linear actuator 33 is articulated on a further bracket 34, which is attached to the cross slide 21.

Wie in Fig. 19 dargestellt, ist erfindungsgemäß an den freien Stabenden der Gitterstäbe 3 eine derartige Ausbildung der Querschnittsabnahme vorgesehen, daß eine in die Einschubrichtung weisende Seitenfläche 1.1 des auf den in der zweiten Lage befindlichen Rechen (8) aufgesetzten Restbogenstapels 1 auf einen erniedrigten Querschnitt der Gitterstäbe 3 abgesenkt ist. Mit dieser Maßnahme werden die Regelvorgänge zum Nachführen der oben genannten Justiereinrichtung in zwei Schritte aufgeteilt, die bei üblichem Ablauf der Vereinigung des Restbogenstapels 1 mit dem Hauptbogenstapel 2 unter Zufhilfenahme der oben beschriebenen Einrichtung mit merklichem zeitlichem Abstand aufeinanderfolgen, wobei bei jedem der Schritte lediglich eine wesentlich kleinere Störgröße auftritt.As shown in FIG. 19, according to the invention, a design of the cross-sectional decrease is provided on the free rod ends of the lattice bars 3 such that a side surface 1.1 of the residual sheet stack 1 placed on the rake (8) located in the second position has a reduced cross-section the bars 3 is lowered. With this measure, the control processes for tracking the above-mentioned adjusting device are divided into two steps, which follow the usual sequence of merging the remaining sheet stack 1 with the main sheet stack 2 with the aid of the device described above with a noticeable time interval, with only one essential in each of the steps smaller disturbance occurs.
