Description

Die Erfindung betrifft eine Vorrichtung zum Stapeln von zwischen zwei Rollen mit vertikaler Achse zugeführten gefalzten Druckprodukten.The invention relates to a device for stacking folded printed products fed between two rolls with a vertical axis.

Mehrfach gefalzte Druckprodukte müssen häufig mit einem weiteren Falz, z.B. Postfalz, versehen und gestapelt werden. Diese Arbeitsvorgänge mußten bisher auf gesonderten, relativ langsam arbeitenden Vorrichtungen ausgeführt werden, die für mit hoher Druckgeschwindigkeit arbeitende Druckereimaschinen ungeeignet sind.Multiple fold printed products often have to be folded with another fold, e.g. Postal fold, provided and stacked. Until now, these operations had to be carried out on separate, relatively slow-moving devices which are unsuitable for high-speed printing machines.

Die Erfindung zielt darauf ab, eine Vorrichtung der einleitend angegebenen Art zu schaffen, die ein Sammeln der gefalzten Druckprodukte in Form von in Kreuzlage übereinander angeordneten Stapeln ermöglicht. Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß den beiden Rollen eine weitere Rolle mit vertikaler Achse nachgeschaltet ist, die quer zur Förderrichtung gesteuert hin- und herbewegbar ist und mit welcher jeweils eine vorbestimmte Anzahl der gefalzten Druckprodukte einer von zwei beiderseits der Vorrichtungslängsachse angeordneten Umlegeeinrichtungen zuleitbar ist, mit welchen die gefalzten Druckprodukte wieder in die Horizontallage überführbar sind, und daß jeder dieser Umlegeeinrichtungen ein Auffangkorb mit einer in vertikaler Richtung auf- und abbewegbaren Gabel nachgeschaltet ist, mit welcher der im Auffangkorb gebildete Stapel auf einen Luftkissentisch absenkbar ist, auf welchem quer zur Förderrichtung bewegbare Schieber zum Querverschieben jedes Stapels gegen die Vorrichtungslängsachse auf eine zentrale Gabel vorgesehen sind, mit welcher der bzw. die Stapel zum Unterschieben jeweils eines neuen, um 180° verdrehten Stapels anhebbar ist bzw. sind.The invention aims to provide a device of the type specified in the introduction which enables the folded printed products to be collected in the form of stacks arranged one above the other in a crosswise position. This object is achieved in that the two rollers are followed by a further roller with a vertical axis, which can be moved back and forth in a controlled manner transversely to the conveying direction and with which a predetermined number of the folded printed products can be fed to one of two folding devices arranged on both sides of the longitudinal axis of the device , with which the folded printed products can be transferred back into the horizontal position, and that each of these transfer devices is followed by a collecting basket with a fork that can be moved up and down in the vertical direction, with which the stack formed in the collecting basket can be lowered onto an air cushion table, on which transversely to In the conveying direction, movable sliders are provided for transversely shifting each stack against the longitudinal axis of the device onto a central fork, with which the stack or stacks can be lifted for pushing in a new stack rotated by 180 °.

Mit Hilfe der erfindungsgemäßen Vorrichtung wird in einem Arbeitsgang mit hohem Durchsatz ein einwandfreies Kreuzstapeln der Druckprodukte gewährleistet.With the aid of the device according to the invention, perfect cross-stacking of the printed products is ensured in one operation with high throughput.

Gemäß einer bevorzugten Ausführungsform der Erfindung sind die Umlegeeinrichtungen durch um eine stromaufwärtige vertikale Umlenkrolle und zwei stromabwärtige horizontale Umlenkrollen geführte Rundriemen gebildet.According to a preferred embodiment of the invention, the folding devices are formed by round belts which are guided around an upstream vertical deflection roller and two downstream horizontal deflection rollers.

Nach einem anderen Erfindungsmerkmal ist die zentrale, in vertikaler Richtung bewegbare Gabel in Ausnehmungen des Luftkissentisches absenkbar und auch in horizontaler Richtung zum Uberführen des Kreuzstapels auf eine nachgeschaltete Fördereinrichtung hin- und herbewegbar.According to another feature of the invention, the central fork, which can be moved in the vertical direction, can be lowered into recesses in the air cushion table and can also be moved back and forth in the horizontal direction for transferring the cross stack to a downstream conveyor.

Weitere Merkmale der Erfindung werden nachfolgend an einem Ausführungsbeispiel unter Bezugnahme auf die Zeichnung näher erläutert. Fig. 1 zeigt eine schematische Seitenansicht einer Vorrichtung gemäß der Erfindung, Fig. 2 eine schematische Draufsicht auf die Vorrichtung nach Fig. 1, und Fig. 3 eine Ansicht in Richtung der Pfeile A-A in Fig. 1.Further features of the invention are explained in more detail below using an exemplary embodiment with reference to the drawing. 1 shows a schematic side view of a device according to the invention, FIG. 2 shows a schematic top view of the device according to FIG. 1, and FIG. 3 shows a view in the direction of the arrows A-A in FIG. 1.

Gefalzte Druckprodukte P werden von einer Fördereinrichtung 1 in Horizontallage vereinzelt zugeführt. Der Fördereinrichtung 1 sind in Förderrichtung (Pfeil F) mehrere Rollenpaare mit quer zur Förderrichtung orientierten Achsen nachgeschaltet. die je aus einer oberen und einer unteren Rolle 2 bzw. 3 bestehen. Die Druckprodukte werden am Falzrücken zwischen den Rollen 2, 3 erfaßt und die beidseits der Rollenpaare bzw. des Falzrückens liegenden Druckproduktabschnitte werden mittels beiderseits der Rollenpaare angeordneten Umklappeinrichtungen 4 beim Durchlauf durch die Rollenpaare fortschreitend um 90° nach unten geklappt. Jede Umklappeinrichtung 4 weist zu diesem Zweck mehrere Rundriemen 5 auf, die um eine der Rollenreihe vorgeschaltete horizontale Rolle 6 und um zwei der Rollenreihe nachgeschaltete vertikale Rollen 7 geschlungen sind.Folded printed products P are fed individually by a conveyor 1 in the horizontal position. The conveyor 1 is followed by several pairs of rollers with axes oriented transversely to the direction of conveyance in the direction of conveyance (arrow F). which each consist of an upper and a lower roll 2 and 3. The printed products are grasped on the fold back between the rollers 2, 3 and the printed product sections lying on both sides of the roll pairs or the fold back are progressively folded down by 90 ° by means of folding devices 4 arranged on both sides of the roll pairs as they pass through the roll pairs. For this purpose, each folding device 4 has a plurality of round belts 5 which are wound around a horizontal roller 6 upstream of the row of rollers and around two vertical rollers 7 connected downstream of the row of rollers.

Die nunmehr mit einem weiteren Falz, z.B. Postfalz, versehenen Druckprodukte durchlaufen den von den Rollen 7 gebildeten Spalt und werden von einer hinter diesem angeordneten, quer zur Förderrichtung zwischen zwei Endstellungen hin- und herbewegbar vertikalen Ablenkrolle 8 nach rechts oder nach links abgelenkt, wobei die Anzahl der jeweils nach einer Seite gelenkten Druckprodukte steuerbar ist. Die Druckprodukte gelangen dabei zwischen Paare von zusammenwirkenden Riementrieben, mit vertikalen Umlenkrollen 9 und Riemen 10. Eine Umlegeeinrichtung 11 wird durch die austragseitige Umlenkrolle 9 jedes Riementriebes und um nachgeschaltete horizontale Umlenkrollen 12 geschlungene zusammenwirkende Riemen 13 gebildet, mit welchen die gefalzten Druckprodukte in die Horizontallage übergeführt werden.Now with another fold, e.g. Postal fold, provided printed products pass through the nip formed by the rollers 7 and are deflected to the right or to the left by a vertical deflecting roller 8 arranged behind the latter, which can be moved back and forth transversely to the conveying direction between two end positions, the number of the printed products directed in each case to one side is controllable. The printed products pass between pairs of interacting belt drives, with vertical deflecting rollers 9 and belts 10. A folding device 11 is formed by the discharge-side deflecting roller 9 of each belt drive and cooperating belts 13 which are looped around downstream horizontal deflecting rollers 12 and with which the folded printed products are transferred into the horizontal position will.

Die mittels der Rundriemen 13 zwangsläufig in die Horizontallage gebrachten Druckprodukte fallen in einen nachgeschalteten Auffangkorb 14 bzw. 15. Ein als Gabel ausgebildeter Boden 14' bzw. 15' jedes Auffangkorbes wird nach Einlauf des letzten Druckproduktes um etwas mehr als die Höhe des gesammelten Stapels S abgesenkt. Der Stapel S wird von einem quer zur Förderrichtung F bewegbaren Schieber 16 bzw. 17 auf einem Luftkissentisch 18 zur Vorrichtungslängsachse auf eine vertikal bewegliche Gabel 19 geschoben und von dieser hochgehoben, so daß ein nachfolgender Stapel S von der anderen Seite daruntergeschoben werden kann. Darauf wird die Gabel 19 entgegen der Förderrichtung F zurückgezogen, so daß der obere Stapel auf dem unteren, um 180° verdrehten Stapel zu liegen kommt. Die Gabel wird dann abwärts bewegt und in Ausnehmungen 18' des Luftkissentisches 18 unter den Stapel geschoben, und es werden beide nun gekreuzt liegenden Stapel hochgehoben. Der Vorgang wiederholt sich, bis z.B. vier Stapel kreuzweise in einem Kreuzstapel S' übereinander liegen. Der Kreuzstapel S' wird von der Gabel 19 hochgehoben und in Förderrichtung F auf ein Förderband 20 übergeführt, das aus mehreren parallel laufenden Bändern besteht, zwischen welche die Zinken der Gabel 19 einfahren können. Der Kreuzstapel wird dann vom Förderband 20 abtransportiert.The printed products inevitably brought into the horizontal position by means of the round belts 13 fall into a downstream collecting basket 14 or 15. A bottom 14 'or 15' of each collecting basket designed as a fork becomes a little more than the height of the collected stack S after the last printed product has entered lowered. The stack S is pushed by a slide 16 or 17 movable transversely to the conveying direction F on an air cushion table 18 to the longitudinal axis of the device on a vertically movable fork 19 and lifted by it, so that a subsequent stack S can be pushed under it from the other side. Then the fork 19 is pulled back against the conveying direction F, so that the upper stack comes to rest on the lower stack rotated by 180 °. The fork is then moved downwards and pushed into recesses 18 'of the air cushion table 18 under the stack, and both stacks, which are now crossed, are lifted up. The process is repeated until e.g. four stacks lie crosswise in a cross stack S 'one above the other. The cross stack S 'is lifted up by the fork 19 and transferred in the conveying direction F to a conveyor belt 20, which consists of several belts running in parallel, between which the tines of the fork 19 can move. The cross stack is then removed from the conveyor belt 20.

Der Arbeitsablauf des Stapelabschnittes der Vorrichtung wird mittels einer nicht gezeigten Programmsteuereinrichtung gesteuert, wobei die Bewegungen der Ablenkrolle 8, der Gabeln 14', 15', der Schieber 16, 17 und der Gabel 19 aufeinander abgestimmt werden.The workflow of the stacking section of the device is by means of a not shown Program control device controlled, the movements of the deflecting roller 8, the forks 14 ', 15', the slider 16, 17 and the fork 19 being coordinated with one another.

Das dargestellte Ausführungsbeispiel kann im Rahmen der Erfindung hinsichtlich der konstruktiven Einzelheiten verschiedentlich abgewandelt werden.The exemplary embodiment shown can be modified in various ways within the scope of the invention with regard to the structural details.
