Description

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum Bilden von Stapeln aus einem kontinuierlich in Richtung eines Stapelschachtes geförderten Schuppenstrom von Druckprodukten.The invention relates to a method and an apparatus for forming stacks from a continuous stream of printed products conveyed in the direction of a stacking shaft.

Bei schnell-laufenden Vorrichtungen der oben genannten Art wird der auf einem Endlosförderer transportierte Schuppenstrom üblicherweise verlangsamt oder sogar angehalten, um eine Lücke zwischen zwei Druckprodukten zu erzeugen. In diese Lücke wird im Stapelschacht ein Zwischenelement eingeführt und auf diesem ein aus den nachfolgenden Druckprodukten bestehender Teilstapel gebildet. Zur Bildung einer solchen Lücke sind auch Lösungen bekannt, bei denen der Schuppenstrom in seinem stromabwärtigen Bereich beschleunigt wird oder bei denen stromaufwärtige Teile des Schuppenstroms verlangsamt und stromabwärtige Teile beschleunigt werden.In fast-running devices of the above type, the shingled stream transported on an endless conveyor is usually slowed or even stopped to create a gap between two printed products. In this gap, an intermediate element is introduced in the stacking shaft and formed on this one of the subsequent printed products existing sub-stack. To form such a gap, solutions are also known in which the scale flow is accelerated in its downstream region or in which upstream parts of the scale flow slows down and downstream parts are accelerated.

Aufgrund derartiger Geschwindigkeitsänderungen gelangt eine Unruhe in den Schuppenstrom, welche die Stapelbildung erschweren oder gar unterbrechen kann. Dabei kann es zu einer veränderten Schuppenlänge bis hin zur negativen Überschuppung sowie zu einem seitlichen Versatz, zu einer Schräglage und auch zu Beschädigungen einzelner oder mehrerer Druckprodukte im Teilstapel und damit zu Problemen beim Bilden des Hauptstapels kommen.Due to such changes in speed a disturbance enters the scale flow, which can complicate the stacking or even interrupt. This can lead to a changed scale length up to the negative overlapping and to a lateral offset, to an inclined position and also to damage of individual or several printed products in the partial stack and to get into problems while making the main pile.

Bei anderen bekannten Vorrichtungen wird der Schuppenstrom dem Stapelschacht kontinuierlich zugeführt, wobei die auf diese Weise gebildeten Stapel erst später getrennt werden. Das entsprechende Verfahren lässt sich jedoch mit vertretbarem Aufwand nicht automatisieren.In other known devices, the shingled stream is fed continuously to the stacking shaft, the stacks formed in this way being separated later. However, the corresponding method can not be automated at a reasonable cost.

Aus der GB2079259 A ist eine Vorrichtung und ein Verfahren bekannt geworden, mit denen ein kontinuierliches Sammeln und Stapeln von Bogen erfolgen soll. Eine entsprechende Stapeleinrichtung umfasst eine Einrichtung zum kontinuierlichen Zusammentragen von Blättern auf einen sich nach unten bewegenden Stapel.From the GB2079259 A An apparatus and a method has become known with which a continuous collection and stacking of sheets is to take place. A corresponding stacking device comprises means for continuously gathering sheets onto a downwardly moving stack.

Dabei wird ein Tisch, auf dem sich die Stapel bilden, in der Stapeleinrichtung vertikal abgesenkt. Beim Absenken dieses Tisches in der Stapeleinrichtung sind Trennmittel vorgesehen, die zum Trennen der Stapel in Teilstapel dienen.In this case, a table on which the stack form, lowered vertically in the stacking device. When lowering this table in the stacking means separating means are provided which serve to separate the stack in partial stack.

Weitere Stapelvorrichtungen sind aus der DE 2725267 B1 , EP0718231 A2 und DE19928367 A1 bekannt.Other stacking devices are from the DE 2725267 B1 . EP0718231 A2 and DE19928367 A1 known.

Aus der DE 19855510 A1 ist eine Vorrichtung zum vertikalen Bilden von Teilstapeln von Druckprodukten bekannt. Hier bewegen sich zwei beidseitig des Stapelschachtes angeordnete Auflagefinger einer Trenneinrichtung in den Bereich des Stapelschachtes hinein. Die Auflagefinger schieben sich zwischen zwei aufeinanderfolgende Druckprodukte des Schuppenstroms und verhindern dadurch das Herabfallen des nachfolgenden Druckproduktes. Durch diese Verzögerung im Schuppenstrom kann die in Form von zwei beidseitig des Stapelschachtes angeordneten Rechen ausgebildete Stapelauflage in die Lücke zwischen den herab fallenden Druckprodukte einfahren und einen sich bildenden Teilstapel aufnehmen. Nachteilig an einer derartigen Einrichtung ist, dass Druckprodukte beim Einführen der Auflagefinger aufgespiesst oder unsauber getrennt werden können, was zu Fehlfunktionen und Standzeiten der gesamten Anlage führen kann.From the DE 19855510 A1 An apparatus for vertically forming sub-stacks of printed products is known. Here, two support fingers of a separating device arranged on both sides of the stacking shaft move into the region of the stacking shaft. The support fingers slide between two successive printed products of the scale flow and thereby prevent the falling of the subsequent printed product. As a result of this delay in the scale flow, the stack support arranged in the form of two rakes arranged on both sides of the stacking shaft can enter into the gap between the printed products which fall down and take up a forming part stack. A disadvantage of such a device is that printed products impaled during insertion of the support fingers or can be separated unclean, which can lead to malfunction and downtime of the entire system.

Aus der DE 19947329 A1 ist ebenfalls eine Vorrichtung bekannt, mit der auf einem Förderband in schuppenförmiger Anordnung angelieferte Druckprodukte vertikal gestapelt und in Form von Teilstapeln einer gewünschten Anzahl ausgegeben werden. Diese Vorrichtung weist einen an der dem Förderband abgewandten Seite des Stapelschachtes angeordneten ersten Auflagefinger auf. Dieser wird aus einer Ausgangsstellung, in der er oberhalb des Schuppenstroms mittig in den Stapelschacht hineinragt, vertikal in eine in den Schuppenstrom hineinragende Endstellung verfahren. Die nach dem Einnehmen der Endstellung des ersten Auflagefingers in den Stapelschacht geförderten Druckprodukte werden somit auf diesem Auflagefinger einen Teilstapel bildend abgelegt. Ein zweiter, an der dem Förderband zugewandten Seite des Stapelschachtes angeordneter Auflagefinger wird ebenfalls in den Stapelschacht eingeführt und dient gemeinsam mit dem ersten Auflagefinger der Abstützung des Teilstapels sowie dessen Trennung vom vorherigen Teilstapel oder vom Hauptstapel. Nachdem die Auflagefinger horizontal aus dem Stapelschacht heraus verfahren worden sind, fallen die Druckprodukte des Teilstapels auf die im Stapelschacht angeordnete Stapelauflage einen Hauptstapel bildend herab. Nachteilig an einer derartigen Vorrichtung ist, dass bei hohen Zuführgeschwindigkeiten des Schuppenstroms dünne Druckprodukte durch die Auflagefinger verformt und beschädigt werden können oder während der Zwischenlagerung beidseitig des jeweiligen Auflagefingers in den Stapelschacht weit unter der Horizontalen hineinragen und deswegen verformt hineinfallen können. Dies kann wiederum zu Fehlfunktionen und Standzeiten der gesamten Anlage führen.From the DE 19947329 A1 An apparatus is also known, with which printed products delivered on a conveyor belt in a flaky arrangement are vertically stacked and output in the form of sub-stacks of a desired number. This device has one on the conveyor belt facing away Side of the stacking shaft arranged first support fingers. This is moved from a starting position in which it protrudes above the scale flow in the middle of the stacking shaft, vertically in a protruding into the scale flow end position. The conveyed after taking the end position of the first support finger in the stacking tray printed products are thus stored forming a partial stack on this support finger. A second support finger arranged on the side of the stacking shaft facing the conveyor belt is likewise introduced into the stacking shaft and, together with the first support finger, serves to support the part stack and separate it from the previous part stack or from the main stack. After the support fingers have been moved horizontally out of the stacking shaft, the printed products of the sub-stack fall on the arranged in the stacking stack support stack forming a main stack. A disadvantage of such a device is that at high feeding speeds of the scale flow thin printed products can be deformed and damaged by the support fingers or protrude far below the horizontal during intermediate storage on both sides of the respective support finger in the stacking shaft and therefore can fall deformed into it. This in turn can lead to malfunction and downtime of the entire system.

Bei Trenneinrichtungen, die an der dem Förderband abgewandten Seite des Stapelschachtes angeordnet und insbesondere als Rechen ausgebildet sind und die mit einer hoher Geschwindigkeit betrieben werden, kann es insbesondere bei Verwendung von dünnen oder grossflächigen Druckprodukten dazu kommen, dass das erste Produkt nach der Trennstelle vom Rechen derart ergriffen wird, dass es teilweise oberhalb und teilweise unterhalb der Finger des Rechens positioniert ist und zudem beschädigt werden kann. Da ein solches verklemmtes Druckprodukt im normalen Produktionsprozess nicht automatisch entfernt werden kann, ist auch hierbei ein Herunterfahren der gesamten Anlage erforderlich.In separation devices, which are arranged on the side facing away from the conveyor belt of the stacking shaft and in particular designed as rakes and operated at a high speed, it may happen, especially when using thin or large-scale printed products that the first product after the separation point of the rake so taken is that it is partially positioned above and partially below the fingers of the rake and can also be damaged. Since such a jammed print product can not be removed automatically in the normal production process, a shutdown of the entire system is also required here.

Aufgabe der Erfindung ist es, ein auch für grosse Verarbeitungsgeschwindigkeiten und zur Verwendung von dünnen Druckprodukten geeignetes einfaches und funktionssicheres Verfahren sowie eine entsprechende Vorrichtung zum Bilden von vertikalen Stapeln aus einem Schuppenstrom von Druckprodukten bereitzustellen.The object of the invention is to provide a suitable for high processing speeds and the use of thin printed products simple and reliable method and a corresponding device for forming vertical stacks of a shingled stream of printed products.

Die Aufgabe wird nach den Merkmalen der Patentansprüche 1 und 5 gelöst. Dabei werden zum Bilden von Stapeln aus einem kontinuierlich in Richtung eines Stapelschachtes auf einem Endlosförderer geförderten Schuppenstrom von Druckprodukten folgende Schritte ausgeführt:

  • Bilden eines Hauptstapels im Stapelschacht auf einer Stapelablage, wobei sich ein Zwischenelement in einer Ruheposition ausserhalb des Stapelschachts befindet,
  • Ausfahren des Zwischenelements in eine Endstellung im Stapelschacht,
  • Ablegen der Druckprodukte auf dem Zwischenelement bzw. auf den jeweils auf diesen bereits befindlichen Druckprodukten, wobei sich auf dem Zwischenelement ein Teilstapel bildet
  • Abtransport des Hauptstapels aus dem Stapelschacht,
  • Einfahren des Zwischenelements in seine Ruheposition ausserhalb des Stapelschachts,
  • Übergabe des bisherigen Teilstapels als neuer Hauptstapel an die Stapelablage, wobei
  • vor dem Ausfahren des Zwischenelements ein in Höhe des Schuppenstroms am Endlosförderer angeordneter Hilfsrechen aus einer Ruheposition ausserhalb des Stapelschachts in eine Endstellung im Stapelschacht ausgefahren wird,
  • Absenken der Stapelablage,
  • Ausbilden eines freien Zwischenraums zwischen Hauptstapel und Teilstapel unterhalb des Hilfsrechens,
  • Ausfahren des Zwischenelements in den freien Zwischenraum und anschliessend in seine Endstellung im Stapelschacht und
  • Einfahren des Hilfsrechens in seine Ruheposition.
The object is solved according to the features of claims 1 and 5. In this case, the following steps are carried out for forming stacks from a continuous flow of printed products conveyed in the direction of a stacking shaft on an endless conveyor:
  • Forming a main stack in the stacking shaft on a stacking tray, wherein an intermediate element is in a rest position outside the stacking shaft,
  • Extending the intermediate element into an end position in the stacking shaft,
  • Depositing the printed products on the intermediate element or on the print products already present thereon, with a partial stack forming on the intermediate element
  • Removal of the main stack from the stacking shaft,
  • Retracting the intermediate element into its rest position outside the stacking shaft,
  • Transfer of the previous sub-stack as a new main stack to the stack tray, where
  • before the intermediate element is extended, an auxiliary rake arranged at the level of the scale flow on the endless conveyor is extended from a rest position outside the stacking shaft into an end position in the stacking shaft,
  • Lowering the stacker tray,
  • Forming a free space between the main stack and the sub-stack underneath the auxiliary rake,
  • Extending the intermediate element in the free space and then in its end position in the stacking shaft and
  • Retracting the auxiliary rake in its rest position.

Ein Vorteil im Bezug auf bisher bekannte Verfahren liegt hier darin, dass der durch den Hilfsrechen gebildete freie Zwischenraum ein Ausfahren des Zwischenelements in eine "sichere Lücke" ermöglicht, ohne dass dabei unkontrolliert in den bisher gebildeten Stapel aus Druckprodukten eingestochen wird. Damit lässt sich eine Verletzung oder Verformung dieser Druckprodukte vermeiden, was zu einer Prozess-Sicherheit auch bei hohen Zuführgeschwindigkeiten führt.An advantage with respect to previously known methods lies in the fact that the free space formed by the auxiliary rake allows an extension of the intermediate element into a "safe gap" without being pierced into the previously formed stack of printed products in an uncontrolled manner. This prevents injury or deformation of these printed products, which leads to process reliability even at high feed rates.

Das Ausfahren des Hilfsrechens aus seiner Ruheposition erfolgt mit annähernd gleicher Geschwindigkeit wie der Schuppenstrom und zumindest annähernd horizontal in den Stapelschacht hinein. Dieser synchronisierte Bewegungsablauf bietet eine zusätzliche Sicherheit für eine saubere Trennung der Produkte an einer gewünschten Stelle, da unterschiedliche Geschwindigkeiten zwischen Hilfsrechen und Schuppenstrom bei hohen Verarbeitungsgeschwindigkeiten zu mechanischen Verformungskräften oder elektrostatischen Aufladungen führen können, die dünne oder grossflächige Druckprodukte beschädigen können.The extension of the auxiliary rake from its rest position takes place at approximately the same speed as the scale flow and at least approximately horizontally into the stacking shaft. This synchronized motion provides additional security for clean separation of products at a desired location, as varying speeds between auxiliary rake and scale flow at high processing speeds can result in mechanical deformation forces or electrostatic charges that can damage thin or large area printed products.

Durch Ansteuern des Hilfsrechens über eine Maschinensteuerung, kann vorteilhaft ein synchrones Ansteuern des Hilfsrechens mit dem Schuppenstrom erfolgen, um die o.g. erforderlichen Bewegungsabläufe innerhalb der Stapelvorrichtung sicherzustellen. Darüber hinaus erfolgt in einer weiteren Ausführungsform das Ansteuern des Hilfsrechens und des Zwischenelements über eine kombinierte Maschinensteuerung. Dies birgt den Vorteil in sich, dass eine noch genauere Ansteuerung der zusammenwirkenden Komponenten der erfindungsgemässen Vorrichtung erzielt werden kann.By controlling the auxiliary rake via a machine control system, a synchronous activation of the auxiliary rake with the shingled stream can advantageously take place in order to obtain the o.g. to ensure necessary movements within the stacking device. In addition, in another embodiment, the driving of the auxiliary rake and the intermediate element takes place via a combined machine control. This has the advantage that an even more accurate control of the interacting components of the inventive device can be achieved.

Dadurch, dass das Bilden von Stapeln bei konstanter Geschwindigkeit des Schuppenstroms erfolgt, ermöglicht die vorliegende Vorrichtung einen verzögerungsfreien Bearbeitungsablauf beim Stapeln der Druckprodukte, wodurch hohe Verarbeitungsgeschwindigkeiten erreicht werden können.By forming stacks at a constant speed of the imbricated flow, the present apparatus enables a delay-free processing in stacking the printed products, whereby high processing speeds can be achieved.

Eine erfindungsgemässe Stapelvorrichtung umfasst einen Endlosförderer und einen stromab des Endlosförderers angeordneten Stapelschacht, mit einem in den Stapelschacht ausfahrbaren, einen Zwischenstapel aufnehmenden Zwischenelement und mit einer im Stapelschacht angeordneten Stapelablage, zum Stapeln eines kontinuierlich in Richtung des Stapelschachts auf dem Endlosförderer geförderten Schuppenstroms von Druckprodukten, wobei die Stapelvorrichtung einen in den Stapelschacht ausfahrbaren in Höhe des Schuppenstroms am Endlosförderer angeordneten Hilfsrechen aufweist, der oberhalb des Zwischenelements angeordnet ist und der mit einer zumindest annähernd gleichen Geschwindigkeit wie der Schuppenstrom und zumindest annähernd horizontal in den Stapelschacht hinein ausfahrbar ist.A stacking device according to the invention comprises an endless conveyor and a stacking shaft arranged downstream of the endless conveyor, with an intermediate element accommodating an intermediate stack and with a stacking tray arranged in the stacking shaft for stacking a continuous flow of printed products conveyed in the direction of the stacking shaft on the endless conveyor the stacking device has an auxiliary rake, which can be extended into the stacking shaft and is arranged on the endless conveyor, which is arranged above the intermediate element and which can be extended into the stacking shaft at at least approximately the same speed as the scale flow and at least approximately horizontally.

In einer weiteren Ausführungsform kann der Hilfsrechen auch mit einer kleineren Geschwindigkeit als der Schuppenstrom in den Stapelschacht eingeführt werden, wobei wegen des sanften Vorausgleitens des Schuppenstroms eine zusätzliche Absicherung gegen eine Verletzung der Druckprodukte erfolgt.In a further embodiment, the auxiliary rake can also be introduced into the stacking shaft at a speed which is less than that of the imbricated flow, with additional protection against infringement of the printed products taking place due to the gentle advance of the imbricated flow.

In einer weiteren Ausführungsform ist der Hilfsrechen so angeordnet ist, dass er sich über eine gesamte Breite des Stapelschachts quer zu einer Förderrichtung des Schuppenstroms erstreckt. Dadurch können grossformatige und dünne Druckprodukte während des erfindungsgemässen Verfahrens noch besser abgestützt werden.In a further embodiment, the auxiliary rake is arranged so that it extends across an entire width of the stacking shaft transversely to a conveying direction of the scale flow. As a result, large-format and thin printed products can be better supported during the process according to the invention.

In einer Ausführungsform der Stapelvorrichtung weisen die Endlosförderer mehrere parallel verlaufende und voneinander beabstandet umlaufende Transportbänder auf. Vorteilhaft erweist sich dabei eine ausfahrbare Anordnung der Hilfsrechen in annähernd gleicher Höhe wie die Transportbänder des Endlosförderers, weil damit eine versatzfreie Übernahme der Druckprodukte von dem Schuppenstrom beim Ausfahren des Hilfsrechens sichergestellt wird.In one embodiment of the stacking device, the endless conveyors have a plurality of parallel and spaced apart circulating conveyor belts. Advantageously proves to be an extendable arrangement of the auxiliary rake in approximately the same height as the conveyor belts of the endless conveyor, because thus an offset-free acquisition of the printed products is ensured by the scale flow when extending the auxiliary rake.

Vorteilhaft erweist sich ebenfalls eine Ausführungsform der Stapelvorrichtung, bei der zwischen den voneinander beabstandeten Transportbändern Zwischenräume ausgebildet sind und der Hilfsrechen in einer eingefahrenen Ruheposition in den Zwischenräumen angeordnet ist. Dadurch kann sichergestellt werden, dass beim Ausfahren des Hilfsrechens in seine Endstellung die Druckprodukte in gleicher Höhe wie auf dem Endlosförderer aufliegen. Dies erweist sich vor allem dann nützlich, wenn grosse Verarbeitungsgeschwindigkeiten erzielt werden sollen und auch bei der Verwendung von dünnen Druckprodukten. Die Umlaufelemente, über welche die Transportbänder geführt sind, können als Rollen, Zahnräder oder ähnliche Bauteile ausgebildet sein, je nach Ausführungsform des Endlosförderers als Band-, Riemen-, Zahnriemen- oder Kettenförderer. Die Antriebseinheiten für das Zwischenelement und den Hilfsrechen können entweder pneumatische, hydraulische, elektrische oder ähnliche Antriebs-Vorrichtungen sein, wobei eine entsprechende Antriebssteuerung für den erfindungsgemässen Bewegungsablauf vorgesehen werden kann.Advantageously, also proves an embodiment of the stacking device, in which spaces are formed between the spaced-apart conveyor belts and the auxiliary rake is arranged in a retracted rest position in the interstices. This can ensure that when the auxiliary rake is extended into its end position, the printed products rest at the same height as on the endless conveyor. This proves especially useful when large processing speeds are to be achieved and also when using thin printed products. The circulating elements, over which the conveyor belts are guided, may be formed as rollers, gears or similar components, depending on the embodiment of the endless conveyor as a belt, belt, toothed belt or chain conveyor. The drive units for the intermediate element and the auxiliary rake can be either pneumatic, hydraulic, electrical or similar drive devices, wherein a corresponding drive control can be provided for the inventive motion sequence.

Die Erfindung wird nachfolgend anhand eines Ausführungsbeispieles in Zusammenhang mit den beiliegenden Zeichnungen näher beschrieben und erläutert.The invention will be described in more detail below with reference to an embodiment in conjunction with the accompanying drawings and explained.

In der Fig. 1 ist eine Ausführungsform der erfindungsgemässen Vorrichtung 1 zum Bilden von Stapeln aus einem Schuppenstrom 2 von Druckprodukten 3 zu sehen: Die Vorrichtung 1 weist einen als Förderband ausgebildeten, horizontalen Endlosförderer 4 und einen daran in einer Förderrichtung anschliessenden, vertikalen Stapelschacht 5 auf. Im Stapelschacht 5 ist eine Stapelablage 6 angeordnet. An der dem Endlosförderer 4 zugewandten Seite des Stapelschachts 5 ist ein als Rechen ausgebildetes Zwischenelement 7 angeordnet.In the Fig. 1 An embodiment of the apparatus 1 according to the invention for forming stacks from a shingled stream 2 of printed products 3 can be seen. The apparatus 1 has a horizontal endless conveyor 4 designed as a conveyor belt and a vertical stacking shaft 5 adjoining it in a conveying direction. In the stacking shaft 5, a stack tray 6 is arranged. At the endless conveyor 4 side facing the stacking shaft 5 designed as a rake intermediate element 7 is arranged.

Zudem weist die Vorrichtung 1 einen Hilfsrechen 8 auf, der in Höhe des Schuppenstromes 2 am Endlosförderer 4 angeordnet und im Wesentlichen horizontal in den Stapelschacht 5 einbringbar ausgebildet ist.In addition, the device 1 has an auxiliary rake 8, which is arranged at the level of the scale flow 2 on the endless conveyor 4 and substantially horizontally formed in the stacking shaft 5 can be introduced.

In den Figuren 2 bis 8 sind die erfindungsgemässen Verfahrensschritte anhand einer Ausführungsform der Vorrichtung 1 dargestellt.In the FIGS. 2 to 8 the method steps according to the invention are illustrated with reference to an embodiment of the device 1.

Fig. 2 zeigt das Bilden eines Hauptstapels 9 im Stapelschacht 5 auf der Stapelablage 6, wobei sich sowohl das Zwischenelement 7 als auch der Hilfsrechen 8 in einer Ruheposition befinden. Dabei wird die Stapelablage 6 entsprechend des anwachsenden Hauptstapels 9 kontinuierlich abgesenkt. Hier ist auch der aus den Druckprodukten 3 gebildete Schuppenstrom 2 auf dem Endlosförderer 4 dargestellt. Fig. 2 shows the formation of a main stack 9 in the stacking shaft 5 on the stack tray 6, wherein both the intermediate element 7 and the auxiliary rake 8 are in a rest position. The stack tray 6 is continuously lowered according to the growing main stack 9. Here, the formed from the printed products 3 Schuppenstrom 2 is shown on the endless conveyor 4.

Fig. 3 zeigt das Ausfahren des Hilfsrechens 8 zwischen die einlaufenden Druckprodukte 3 des Schuppenstroms 2 beim Erreichen der für den Hauptstapel 9 vorgesehenen Anzahl von Druckprodukten 3. Dabei wird der Hilfsrechen 8 mit annähernd gleicher Geschwindigkeit wie der Schuppenstrom 2 und zumindest annähernd horizontal in den Stapelschacht 5 bewegt. Die stromaufwärtigen Enden der Druckprodukte 3 werden nunmehr auf dem Hilfsrechen 8 abgestützt, während die stromabwärtigen Enden dieser Druckprodukte 3 weiterhin auf der Stapelablage 6 bzw. auf den bereits auf dieser befindlichen Druckprodukten 3 des Hauptstapels 9 abgelegt werden. Fig. 3 shows the extension of the auxiliary rake 8 between the incoming printed products 3 of the scale flow 2 upon reaching the number of printed products 3 provided for the main stack 9. The auxiliary rake 8 is moved into the stacking shaft 5 at approximately the same speed as the scale flow 2 and at least approximately horizontally. The upstream ends of the printed products 3 are now supported on the auxiliary rake 8, while the downstream ends of these printed products 3 are further deposited on the stack tray 6 and on the printed products 3 of the main stack 9 already located thereon.

Fig. 4 zeigt den Hilfsrechen 8 in seiner ausgefahrenen Endstellung. Gleichzeitig mit dem Erreichen dieser Endstellung des Hilfsrechens 8 werden die Stapelablage 6 und damit auch der Hauptstapel 9 abgesenkt, wobei ein freier Zwischenraum 10 für das Ausfahren des Zwischenelements 7 gebildet wird. Der Hilfsrechen 8 bildet selbst keinen Teilstapel, verhindert aber, dass die stromabwärtigen Enden der Druckprodukte 3 weiter in den Stapelschacht 5 fallen können. In den vom Hilfsrechen 8 erzeugten Zwischenraum 10 kann das Zwischenelement 7 ohne Beschädigung von Druckprodukten 3 einfahren. Fig. 4 shows the auxiliary rake 8 in its extended end position. Simultaneously with the achievement of this end position of the auxiliary rake 8, the stack tray 6 and thus also the main stack 9 are lowered, wherein a free space 10 is formed for the extension of the intermediate element 7. The auxiliary rake 8 itself does not form a partial stack, but prevents the downstream ends of the printed products 3 from falling further into the stacking shaft 5. In the space 10 generated by the auxiliary rake 8, the intermediate element 7 can retract without damaging printed products 3.

Fig. 5 stellt das Zwischenelement 7 in seiner ausgefahrenen Endstellung dar, in welcher die stromabwärtigen Enden der bereits bis dahin auf dem Hauptstapel 9 abgelegten Druckprodukte 3 vom Zwischenelement 7 übernommen worden sind. Die nachfolgenden Druckprodukte 3 werden nun jeweils mit ihrem stromaufwärtigen Ende auf dem Hilfsrechen 8 und mit ihrem stromabwärtigen Ende auf dem Zwischenelement 7 bzw. auf den jeweils auf diesen bereits befindlichen Druckprodukten 3 abgelegt. Fig. 5 represents the intermediate element 7 in its extended end position, in which the downstream ends of the previously deposited so far on the main stack 9 printed products 3 have been taken over by the intermediate element 7. The following printed products 3 are now deposited in each case with their upstream end on the auxiliary rake 8 and with its downstream end on the intermediate element 7 or on the respective printed products 3 already located thereon.

Fig. 6 zeigt in seine Ruheposition einfahrenden Hilfsrechen 8, wodurch die stromaufwärtigen Enden der zuvor auf dem Hilfsrechen abgelegten Druckprodukte 3 unter Ausbildung eines Teilstapels 11 an das Zwischenelement 7 übergeben werden. Die weitere Ausbildung des Teilstapels 11 erfolgt dann auf dem sich absenkenden Zwischenelement 7, wobei der Hauptstapel 9 mit der Stapelablage 6 weiter abgesenkt wird. Fig. 6 shows in its rest position entering auxiliary rake 8, whereby the upstream ends of the previously stored on the auxiliary rake printed products 3 are transferred to the intermediate element 7 to form a partial stack 11. The further formation of the sub-stack 11 then takes place on the self-lowering intermediate element 7, wherein the main stack 9 is further lowered with the stack tray 6.

Fig. 7 deutet das nach dem nicht dargestellten Abtransport des Hauptstapels 9 erfolgende Hochfahren der Stapelablage 6 bis unter das Zwischenelement 7 an, wobei letzteres beim Erreichen der oberen Position der Stapelablage 6 in seine Ruheposition eingefahren und der Teilstapel 11 an die Stapelablage 6 übergeben wird. Die sich nunmehr anschliessende Ausbildung des Hauptstapels 4 erfolgt auf der Stapelablage 6, analog Fig. 2. Fig. 7 indicates after the removal of the main stack 9 not shown taking off the stack tray 6 to below the intermediate element 7, the latter being retracted on reaching the upper position of the stack tray 6 in its rest position and the part stack 11 is transferred to the stack tray 6. The now subsequent training of the main stack 4 takes place on the stack tray 6, analog Fig. 2 ,
