Definitions

  • the present invention relates to a device for stacking printed products, in particular in a shingled stream, according to the preamble of claim 1.
  • Such a device is known from DE-OS 14 36 495. It has a stacking shaft with a lifting and lowering stacking table.
  • a feed conveyor is connected upstream of the stacking table, which is pivotable about a pivot axis arranged in the region of its beginning and, in the working position, is supported on the stack to be formed in the region of its end opening into the stacking shaft.
  • the feed conveyor has an arm protruding over its end, on which a rotatably driven swirl wheel is arranged in order to support the feed conveyor and at the same time to convey the supplied printed products against a stop.
  • the stacking table is in its upper end position and the feed conveyor adapts to the respective stack height by pivoting about its pivot axis.
  • the feed is interrupted and the feed conveyor is pivoted into its upper end position.
  • the stacking table is lowered, as a result of which the stack is placed on a belt conveyor, which conveys it away in the feed direction of the printed products. Then the stacking table is raised again and the feed conveyor is lowered to form a new stack.
  • Such stacks generally have poor stability, in particular if they are formed from folded printed products, because these printed products have a greater thickness in the region of the fold than at the edge region opposite the fold. The permissible stack height is therefore considerably restricted.
  • a device with two stacking shafts is known for example from DE-OS 27 52 513 and the corresponding GB-PS 1 568 752.
  • each stacking shaft is preceded by a partial stacking device and this in turn is a feed conveyor fixedly arranged in a frame.
  • the stacking shafts can be separated from the corresponding partial stacking devices by means of slides.
  • the printed products fed in a shingled stream reach the feed conveyor by means of a further conveyor upstream of the feed conveyor and are transported by the latter to the partial stack forming device.
  • the print products fall within the boundaries on the slider or on existing print products.
  • opening the slide causes the partial stack formed to be dropped onto a height-adjustable stacking table or onto the partial stack already on it, while the printed products of the shingled stream are fed to the partial stacking device which is assigned to the second stacking shaft will.
  • the slides are moved into their closed position, so that the partial stacking device is ready to receive further printed products.
  • the stacking table with the partial stacks arranged on it is now rotated through a vertical axis by 180 ° and, if necessary, raised to press the partial stack against the slides and then slightly lowered again.
  • a partial stack is alternately formed in each of the two partial stack forming devices and placed crosswise on the stacking table in the stacking shaft.
  • the stacking table is lowered completely and the package formed from cross-stacked partial stacks by means of an ejector, as is known for example from CH-PS 623 287 and the corresponding US Pat. No. 4,229,134. pushed out.
  • the object of the present invention is to develop the device mentioned at the outset in such a way that high-quality stacks can be formed at high processing speed.
  • the upper part of the stacking shaft is provided with holding elements which can be moved into and out of the stacking shaft.
  • the holding elements When the holding elements are retracted, the printed products located in the stacking shaft can be pressed into a compact partial stack or finished stack by lifting the stacking table, which permits a greater overall stack height.
  • these holding elements together with the stacking shaft can be rotated periodically about an essentially vertical axis, preferably by 180 ° in each case, the formation of stacks with partial stacks rotated relative to one another is made possible. Since the stacking shaft can be rotated with the holding elements retracted, it can be rotated quickly without the stack shifting. Thus, the cycle time for forming a stack can be shortened considerably.
  • the device has a plurality of stacking shafts, with a feeding conveyor being connected upstream of each stacking shaft. This allows the stacking of continuously occurring printed products, since these alternate in different sections Stacking shafts can be fed.
  • a preferred method for operating such a device is specified in claim 9.
  • FIG. 1 schematically shows a device which stacks the folded printed products, such as newspapers, magazines or the like, which accumulate in a shingled stream. The individual stacks are then processed further.
  • the device has three feed devices 10, 10 ', 10 "and stacking devices 12, 12', 12" arranged one behind the other on a support frame 8. Since these devices are constructed identically, only one is described in more detail.
  • the printed products 14 are fed by a conveyor 16.
  • the transporter 16 has controlled grippers 18 anchored at intervals on a pulling element, not shown, each of which holds a printed product 14. Such grippers are described, for example, in CH-PS 592,562 and the corresponding US-PS 3,955,667.
  • the grippers 18 are moved in the direction of the arrow A and, in the case of a release device 20, 20 ′, 20 ′′, release the respective printed product 14.
  • the incoming printed products 14 are fed with their fold ahead in a shingled stream S.
  • the feed device 10 has a storage belt conveyor 22, an infeed belt conveyor 24 connected downstream of this and an in turn feed conveyor 26 downstream of this.
  • a side judge 28, only shown schematically, is assigned to the infeed belt conveyor 24 and aligns the side edges of the printed products 14 with one another.

  • the rocker 30 is pivotally mounted on a pivot shaft 36 in the initial region of the feed conveyor 26 and can be brought into a shown working position and a rest position indicated by dash-dotted lines by means of a lifting cylinder unit 38.
  • the endless belt conveyors 32, 34 are guided around rollers 40 rotatably mounted on the rocker 30, the start-side roller 40 'of the belt conveyor 34 being arranged coaxially to the pivot shaft 36.
  • the conveyor-effective dreams of the two belt conveyors 32 and 34 form an inlet opening 42 in the initial region of the feed conveyor 26 and, viewed in the conveying direction F, are then guided parallel to one another, so that they form a narrow conveyor gap 44.
  • the end of the conveyor gap 44 opens into a stacking shaft 46 of the stacking device 12.
  • the feed conveyor 26 has a protruding support member 48 at its end, which is described in more detail below.
  • a sensor 49 is mounted on the support frame 8, which detects the swiveling of the feed conveyor 26 out of its “field of view” and generates a control signal.
  • the stacking shaft 46 is arranged on a frame 50.
  • a stacking table 56 is guided in a height-adjustable manner on two vertical guide rods 52, which are connected to one another at their upper end by a frame 54.
  • the stacking table 56 is connected to a piston rod 58 of a lifting / lowering drive which is arranged in the frame 50.
  • 60 denotes an ejector, which is described in more detail below; it serves to eject the stack 61 ′ formed from partial stacks 61.
  • the stacking table 56 is raised in the stacking device 12 of FIG. 1 into the upper region of the stacking shaft 46, while it is completely lowered in the stacking device 12 'and supports two cross-stacked partial stacks 61.
  • the stacking table 56 is likewise lowered in the stacking device 12 ′′, and there are no printed products 14 in its stacking shaft 46.
  • the printed products 14 supplied by the transporter 16 in a shingled stream S are released in the region of the triggering device 20 by the gripper 18 and placed on the deposit belt conveyor 22.
  • the direction of conveyance of the effective strands of the conveyor belt conveyor 22, the infeed conveyor 24 and the direction of conveyance F of the feed conveyor 26 are in the same direction as those of the conveyor 16 (arrow A).
  • the printed products 14 pass from the deposit belt conveyor 22 to the infeed belt conveyor 24, where the side edges of the printed products 14 are aligned with one another by the side judge 28.
  • the infeed belt conveyor 24 transports the printed products 14 to the inlet opening 42 of the feed conveyor 26. There they arrive in the conveyor gap 44 and are conveyed to the stacking shaft 46.
  • FIG. 2 shows a side view of the end of the feed conveyor 26 with the support member 48 and the stacking shaft 46, partially in section.
  • the rollers 40 of the belt conveyors 32 and 34 are rotatably mounted on the rocker 30.
  • the support member 48 has a C-profile 62 in which an arm 64 is guided telescopically.
  • the C-profile 62 is adjustable by means of a holding piece 66, but is non-rotatably attached to the rocker 30.
  • a swirl 68 is rotatably mounted.

Abstract

Printed products are infed in an imbricated formation by a transport device to a stacker apparatus. These printed products are transported by a delivery belt conveyor and an infeed belt conveyor to a pivotably mounted infeed device. The outfeed end region of the infeed device opens into a stacker chute of a stacker device. At the infeed device there is arranged a support element. The printed products delivered by the infeed device to the stacker chute slide onto an elevationally displaceable stacker table. This infeed device is supported by the support element upon the stacked printed products. Governed by the pivotal motion of the infeed device, the stacker table of the stacker chute is incrementally lowered. As soon as sufficient printed products are available for forming a first partial stack in the stacker chute, this first partial stack is pressed by presser structure comprising piston-and-cylinder units and then this first partial stack is rotated about an upright axis through about 180 DEG in conjunction with the stacker chute. Now a second partial stack, turned through about 180 DEG with respect to the first partial stack, can be formed upon the first partial stack. At the stacker apparatus, there are arranged a number of such infeed devices and stacker devices, so that during product pressing and turning of a partial stack the infed printed products can be delivered to a further one of the stacker devices for product stack formation.

Description

Die vorliegende Erfindung bezieht sich auf eine Vorrichtung zum Stapeln von insbesondere in einem Schuppenstrom anfallenden Druckereiprodukten gemäss dem Oberbegriff des Anspruches 1.The present invention relates to a device for stacking printed products, in particular in a shingled stream, according to the preamble of claim 1.

Eine solche Vorrichtung ist aus der DE-OS 14 36 495 bekannt. Sie weist einen Stapelschacht mit einem heb- und senkbaren Stapeltisch auf. Dem Stapeltisch ist ein Zuförderer vorgeschaltet, der um eine im Bereich seines Anfangs angeordnete Schwenkachse schwenkbar und in Arbeitsstellung im Bereich seines in den Stapelschacht ausmündenden Endes auf dem zu bildenden Stapel abgestützt ist. Zu diesem Zweck weist der Zuförderer einen über sein Ende vorstehenden Arm auf, an welchem ein drehbar angetriebenes Schwirbelrad angeordnet ist, um den Zuförderer abzustützen und gleichzeitig die zugeführten Druckereiprodukte gegen einen Anschlag zu fördern. Während der Stapelbildung befindet sich der Stapeltisch in seiner oberen Endlage und der Zuförderer passt sich durch Verschwenken um seine Schwenkachse der jeweiligen Stapelhöhe an. Sobald genügend Druckereiprodukte aufgestapelt sind, wird die Zuführung unterbrochen und der Zuförderer in seine obere Endlage verschwenkt. Der Stapeltisch wird abgesenkt, wodurch der Stapel auf einem Bandförderer abgelegt wird, welcher diesen in Zuführrichtung der Druckereiprodukte wegfördert. Dann wird der Stapeltisch wieder angehoben und der Zuförderer zur Bildung eines neuen Stapels abgesenkt. Solche Stapel weisen in der Regel, insbesondere wenn sie aus gefalteten Druckereiprodukten gebildet sind, eine schlechte Stabilität auf, weil diese Druckereiprodukte im Bereich des Falzes eine grössere Dicke aufweisen als an dem dem Falt gegenüberliegenden Randbereich. Die zulässige Stapelhöhe ist somit beträchtlich eingeschränkt.Such a device is known from DE-OS 14 36 495. It has a stacking shaft with a lifting and lowering stacking table. A feed conveyor is connected upstream of the stacking table, which is pivotable about a pivot axis arranged in the region of its beginning and, in the working position, is supported on the stack to be formed in the region of its end opening into the stacking shaft. For this purpose, the feed conveyor has an arm protruding over its end, on which a rotatably driven swirl wheel is arranged in order to support the feed conveyor and at the same time to convey the supplied printed products against a stop. During the stack formation, the stacking table is in its upper end position and the feed conveyor adapts to the respective stack height by pivoting about its pivot axis. As soon as enough printed products have been piled up, the feed is interrupted and the feed conveyor is pivoted into its upper end position. The stacking table is lowered, as a result of which the stack is placed on a belt conveyor, which conveys it away in the feed direction of the printed products. Then the stacking table is raised again and the feed conveyor is lowered to form a new stack. Such stacks generally have poor stability, in particular if they are formed from folded printed products, because these printed products have a greater thickness in the region of the fold than at the edge region opposite the fold. The permissible stack height is therefore considerably restricted.

Eine Vorrichtung mit zwei Stapelschächten ist beispielsweise aus der DE-OS 27 52 513 und der entsprechenden GB-PS 1 568 752 bekannt. Bei dieser Vorrichtung ist jedem Stapelschacht eine Teilstapelbildeeinrichtung vorgeschaltet und dieser wiederum ein in einem Gestell fest angeordneter Zuförderer. Die Stapelschächte sind durch Schieber von den entsprechenden Teilstapelbildeeinrichtungen abtrennbar. Die in einem Schuppenstrom zugeführten Druckereiprodukte gelangen mittels eines, dem Zuförder vorgeschalteten weiteren Förderers auf den Zuförderer und werden von diesem zur Teilstapelbildeeinrichtung transportiert. Die Druckereiprodukte fallen innerhalb Begrenzungsleisten auf die Schieber oder auf bereits auf diesen vorhandene Druckereiprodukte. Sobald genügend Exemplare der Druckereiprodukte auf dem Teilstapel vorhanden sind, wird durch Oeffnen der Schieber der gebildete Teilstapel auf einen höhenverstellbaren Stapeltisch oder auf den sich bereits auf diesem befindenden Teilstapel fallengelassen, während die Druckereiprodukte des Schuppenstromes der Teilstapeleinrichtung, die dem zweiten Stapelschacht zugeordnet ist, zugeführt werden. Nach dem Absenken des Stapeltisches werden die Sch ieber in ihre Schliessstellung überführt, so dass die Teilstapelbildeeinrichtung zur Aufnahme weiterer Druckereiprodukte bereit ist. Um ein kreuzweises Aufstapeln der Teilstapel zu gewährleisten, wird nun der Stapeltisch mit den auf ihm angeordneten Teilstapeln um eine vertikale Achse um 180° gedreht und gegebenenfalls zum Pressen des Teilstapels gegen die Schieber angehoben und anschliessend wieder leicht abgesenkt. Auf diese Art und Weise wird abwechslungsweise in jeder der beiden Teilstapelbildeeinrichtungen ein Teilstapel gebildet und in den Stapelschacht je kreuzweise auf den Stapeltisch abgelegt. Sobald die Teilstapel in einem Stapelschacht die Gesamtstapelhöhe erreicht haben, wird der Stapeltisch ganz abgesenkt und das aus kreuzweise übereinandergelegten Teilstapeln gebildete Paket mittels eines Ausstossers, wie er beispielsweise aus der CH-PS 623 287 und der entsprechenden US-PS 4 229 134 bekannt ist, ausgestossen.A device with two stacking shafts is known for example from DE-OS 27 52 513 and the corresponding GB-PS 1 568 752. In this device, each stacking shaft is preceded by a partial stacking device and this in turn is a feed conveyor fixedly arranged in a frame. The stacking shafts can be separated from the corresponding partial stacking devices by means of slides. The printed products fed in a shingled stream reach the feed conveyor by means of a further conveyor upstream of the feed conveyor and are transported by the latter to the partial stack forming device. The print products fall within the boundaries on the slider or on existing print products. As soon as there are enough copies of the printed products on the partial stack, opening the slide causes the partial stack formed to be dropped onto a height-adjustable stacking table or onto the partial stack already on it, while the printed products of the shingled stream are fed to the partial stacking device which is assigned to the second stacking shaft will. After the stacking table has been lowered, the slides are moved into their closed position, so that the partial stacking device is ready to receive further printed products. In order to ensure that the partial stacks are stacked crosswise, the stacking table with the partial stacks arranged on it is now rotated through a vertical axis by 180 ° and, if necessary, raised to press the partial stack against the slides and then slightly lowered again. In this way, a partial stack is alternately formed in each of the two partial stack forming devices and placed crosswise on the stacking table in the stacking shaft. As soon as the partial stacks in a stacking shaft have reached the total stack height, the stacking table is lowered completely and the package formed from cross-stacked partial stacks by means of an ejector, as is known for example from CH-PS 623 287 and the corresponding US Pat. No. 4,229,134. pushed out.

Aufgabe der vorliegenden Erfindung ist es, die eingangs genannte Vorrichtung derart weiterzubilden, dass mit grosser Verarbeitungsgeschwindigkeit qualitativ hochstehende Stapel gebildet werden können.The object of the present invention is to develop the device mentioned at the outset in such a way that high-quality stacks can be formed at high processing speed.

Diese Aufgabe wird durch die Merkmale des kennzeichnenden Teiles des Anspruchs 1 gelöst.This object is achieved by the features of the characterizing part of claim 1.

Der Stapelschacht ist in seinem oberen Bereich mit Halteelementen versehen, die in den Stapelschacht einfahrbar und aus diesem ausfahrbar sind. Bei eingefahrenen Halteelementen können durch Anheben des Stapeltisches die sich im Stapelschacht befindenden Druckereiprodukte zu einem kompakten Teilstapel bzw. Fertigstapel gepresst werden, was eine grössere Gesamtstapelhöhe zulässt. Da diese Halteelemente zusammen mit dem Stapelschacht um eine im wesentlichen vertikale Achse periodisch, vorzugsweise um jeweils 180°, drehbar sind, wird die Bildung von Stapeln mit gegeneinander verdrehten Teilstapeln ermöglicht. Da der Stapelschacht mit eingefahrenen Halteelementen gedreht werden kann, ist ein schnelles Drehen möglich, ohne dass sich dabei der Stapel verschiebt. Somit kann dieZykiuszeitfürdie Bildung eines Stapels erheblich verkürzt werden.The upper part of the stacking shaft is provided with holding elements which can be moved into and out of the stacking shaft. When the holding elements are retracted, the printed products located in the stacking shaft can be pressed into a compact partial stack or finished stack by lifting the stacking table, which permits a greater overall stack height. Since these holding elements together with the stacking shaft can be rotated periodically about an essentially vertical axis, preferably by 180 ° in each case, the formation of stacks with partial stacks rotated relative to one another is made possible. Since the stacking shaft can be rotated with the holding elements retracted, it can be rotated quickly without the stack shifting. Thus, the cycle time for forming a stack can be shortened considerably.

Da die Druckereiprodukte vom Zuförderer direkt in den Stapelschacht transportiert werden, entfällt eine Teilstapelbildeeinrichtung, wie sie aus der weiter oben gewürdigten DE-OS 27 52 513 und der entsprechenden GB-PS 1 568 752 bekannt ist.Since the printed products are transported directly from the feed conveyor into the stacking shaft, there is no need for a partial stacking device as is known from DE-OS 27 52 513 and GB-PS 1 568 752, which was recognized above.

In einer besonders bevorzugten Ausführungsform gemäss Anspruch 6 weist die Vorrichtung mehrere Stapelschächte auf, wobei jedem Stapelschacht ein Zuförderervorgeschaltet ist. Dies erlaubt das Stapeln von kontinuierlich anfallenden Druckereiprodukten, da diese abwechslungsweise sektionsweise verschiedenen Stapelschächten zugeführt werden können.In a particularly preferred embodiment according to claim 6, the device has a plurality of stacking shafts, with a feeding conveyor being connected upstream of each stacking shaft. This allows the stacking of continuously occurring printed products, since these alternate in different sections Stacking shafts can be fed.

Weitere bevorzugte Ausführungsformen sind in den abhängigen Ansprüchen angegeben.Further preferred embodiments are specified in the dependent claims.

Ein bevorzugtes Verfahren zum Betrieb einer solchen Vorrichtung ist im Anspruch 9 angegeben.A preferred method for operating such a device is specified in claim 9.

Die einzelnen Stapel werden anschliessend weiter verarbeitet.1 schematically shows a device which stacks the folded printed products, such as newspapers, magazines or the like, which accumulate in a shingled stream. The individual stacks are then processed further.

Die Vorrichtung weist je drei hintereinander, an einem Traggestell 8 angeordnete Zubringeinrichtungen 10, 10', 10" und Stapeleinrichtungen 12, 12', 12" auf. Da diese Einrichtungen identisch aufgebaut sind, wird nur eine näher beschrieben.The device has three feed devices 10, 10 ', 10 "and stacking devices 12, 12', 12" arranged one behind the other on a support frame 8. Since these devices are constructed identically, only one is described in more detail.

Die Druckereiprodukte 14 werden durch einen Transporteur 16 zugeführt. Der Transporteur 16 weist an einem nicht gezeigten Zugorgan in Abständen verankerte, gesteuerte Greifer 18 auf, von denen jeder ein Druckereiprodukt 14 festhält. Solche Greifer sind beispielsweise in der CH-PS 592.562 und der entsprechenden US-PS 3,955,667 näher beschrieben. Die Greifer 18 werden in Richtung des Pfeiles A bewegt und geben bei einer Auslösevorrichtung 20, 20', 20" das jeweilige Druckereiprodukt 14 frei. Die ankommenden Druckereiprodukte 14 werden mit ihrem Falz voraus in einem Schuppenstrom S zugeführt.The printed products 14 are fed by a conveyor 16. The transporter 16 has controlled grippers 18 anchored at intervals on a pulling element, not shown, each of which holds a printed product 14. Such grippers are described, for example, in CH-PS 592,562 and the corresponding US-PS 3,955,667. The grippers 18 are moved in the direction of the arrow A and, in the case of a release device 20, 20 ′, 20 ″, release the respective printed product 14. The incoming printed products 14 are fed with their fold ahead in a shingled stream S.

Die Zubringeinrichtung 10 weist einen Ablagebandförderer 22, einen diesem nachgeschalteten Einlaufbandförderer 24 sowie einen wiederum diesem nachgeschalteten Zuförderer26 auf. Dem Einlaufbandförderer 24 ist ein nur schematisch dargestellter Seitenrichter 28 zugeordnet, welcher die Seitenkanten der Druckereiprodukte 14 zueinander ausrichtet. Im Zuförderer 26 sind an einer Wippe 30 zwei Bandförderer 32, 34 angeordnet. Die Wippe 30 ist im Anfangsbereich des Zuförderers 26 an einer Schwenkwelle 36 schwenkbar gelagert und mittels eines Hubzylinderaggregates 38 in eine dargestellte Arbeitsstellung und eine strichpunktiert angedeutete Ruhestellung bringbar. Die endlosen Bandförderer 32, 34 sind um an der Wippe 30 drehbar gelagerte Rollen 40 geführt, wobei die anfangsseitige Rolle 40' des Bandförderers 34 koaxial zur Schwenkwelle 36 angeordnet ist. Die förderwirksamen Trume der beiden Bandförderer 32 und 34 bilden im Anfangsbereich des Zuförderers 26 eine Einlassöffnung 42 und sind, in Förderrichtung F gesehen, anschliessend parallel zueinander geführt, so dass sie einen engen Förderspalt 44 bilden. Das Ende des Förderspaltes 44 mündet in einen Stapelschacht 46 der Stapeleinrichtung 12. Der Zuförderer 26 weist an seinem Ende ein vorstehendes Abstützorgan 48 auf, dieses wird weiter unten noch näher beschrieben. Am Traggestell 8 ist ein Sensor 49 montiert, der das Ausschwenken des Zuförderers 26 aus seinem "Blickfeld" erfasst und ein Steuersignal erzeugt.The feed device 10 has a storage belt conveyor 22, an infeed belt conveyor 24 connected downstream of this and an in turn feed conveyor 26 downstream of this. A side judge 28, only shown schematically, is assigned to the infeed belt conveyor 24 and aligns the side edges of the printed products 14 with one another. In the feed conveyor 26, two belt conveyors 32, 34 are arranged on a rocker 30. The rocker 30 is pivotally mounted on a pivot shaft 36 in the initial region of the feed conveyor 26 and can be brought into a shown working position and a rest position indicated by dash-dotted lines by means of a lifting cylinder unit 38. The endless belt conveyors 32, 34 are guided around rollers 40 rotatably mounted on the rocker 30, the start-side roller 40 'of the belt conveyor 34 being arranged coaxially to the pivot shaft 36. The conveyor-effective dreams of the two belt conveyors 32 and 34 form an inlet opening 42 in the initial region of the feed conveyor 26 and, viewed in the conveying direction F, are then guided parallel to one another, so that they form a narrow conveyor gap 44. The end of the conveyor gap 44 opens into a stacking shaft 46 of the stacking device 12. The feed conveyor 26 has a protruding support member 48 at its end, which is described in more detail below. A sensor 49 is mounted on the support frame 8, which detects the swiveling of the feed conveyor 26 out of its “field of view” and generates a control signal.

In der fahrbaren Stapeleinrichtung 12 ist auf einem Gestell 50 der Stapelschacht 46 angeordnet An zwei senkrechten Führungsstangen 52, welche an ihrem oberen Ende mit einem Rahmen 54 miteinander verbunden sind, ist ein Stapeltisch 56 höhenverstellbar geführt. Zu diesem Zweck ist der Stapeltisch 56 mit einer Kolbenstange 58 eines Hub-Senkantriebes, welcher im Gestell 50 angeordnet ist, verbunden. Mit 60 ist ein Ausstosser bezeichnet, der weiter unten näher beschrieben wird, er dient zum Ausstossen des aus Teilstapeln 61 gebildeten Stapels 61'.In the mobile stacking device 12, the stacking shaft 46 is arranged on a frame 50. A stacking table 56 is guided in a height-adjustable manner on two vertical guide rods 52, which are connected to one another at their upper end by a frame 54. For this purpose, the stacking table 56 is connected to a piston rod 58 of a lifting / lowering drive which is arranged in the frame 50. 60 denotes an ejector, which is described in more detail below; it serves to eject the stack 61 ′ formed from partial stacks 61.

Der Stapeltisch 56 ist in der Stapeleinrichtung 12 der Fig. 1 in den oberen Bereich des Stapelschachtes 46 angehoben, während er in der Stapeleinrichtung 12' ganz abgesenkt ist und zwei kreuzweise geschichtete Teilstapel 61 abstützt. In der Stapeleinrichtung 12" ist der Stapeltisch 56 ebenfalls abgesenkt, in ihrem Stapelschacht 46 befinden sich keine Druckereiprodukte 14.The stacking table 56 is raised in the stacking device 12 of FIG. 1 into the upper region of the stacking shaft 46, while it is completely lowered in the stacking device 12 'and supports two cross-stacked partial stacks 61. The stacking table 56 is likewise lowered in the stacking device 12 ″, and there are no printed products 14 in its stacking shaft 46.

Die vom Transporteur 16,in einem Schuppenstrom S zugeführten Druckereiprodukte 14 werden im Bereich der Auslösevorrichtung 20 vom Greifer 18 freigegeben und auf den Ablagebandförderer 22 abgelegt. Die Förderrichtung der wirksamen Trume des Ablagebandförderers 22, des Einlaufbandförderers 24 sowie die Förderrichtung F des Zuförderers 26 sind gleichsinnig wie jene des Transporteurs 16 (Pfeil A). Die Druckereiprodukte 14 gelangen vom Ablagebandförderer 22 zum Einlaufbandförderer 24, wo die Seitenkanten der Druckereiprodukte 14 mittels dem Seitenrichter 28 aufeinander ausgerichtet werden. Der Einlaufbandförderer 24 transportiert die Druckereiprodukte 14 zur Einlassöffnung 42 des Zuförderers 26. Dort gelangen diese in den Förderspalt 44 und werden zum Stapelschacht 46 gefördert.The printed products 14 supplied by the transporter 16 in a shingled stream S are released in the region of the triggering device 20 by the gripper 18 and placed on the deposit belt conveyor 22. The direction of conveyance of the effective strands of the conveyor belt conveyor 22, the infeed conveyor 24 and the direction of conveyance F of the feed conveyor 26 are in the same direction as those of the conveyor 16 (arrow A). The printed products 14 pass from the deposit belt conveyor 22 to the infeed belt conveyor 24, where the side edges of the printed products 14 are aligned with one another by the side judge 28. The infeed belt conveyor 24 transports the printed products 14 to the inlet opening 42 of the feed conveyor 26. There they arrive in the conveyor gap 44 and are conveyed to the stacking shaft 46.

In der Fig. 2 ist in Seitenansicht das Ende des Zuförderers 26 mit dem Abstützorgan 48 und der Stapelschacht 46 teilweise geschnitten dargestellt An der Wippe 30 sind die Rollen 40 der Bandförderer 32 bzw. 34 drehbar gelagert. Das Abstützorgan 48 weist ein C-Profil 62 auf, in dem teleskopartig ein Arm 64 verschiebbar geführt ist. Das C-Profil 62 ist mittels einem Haltestück 66 einstellbar, aber drehfest an der Wippe 30 befestigt. Am freien Ende des Armes 64 ist ein Schwirbel 68 drehbar gelagert. Dieser weist eine z.B. mittels eines Bandes 70 antreibbare, kreisförmige Scheibe 72 auf, an deren Peripherie frei drehbar gelagerte Rollen 74 angeordnet sind. Das Band 70 wird von einem Abtriebsrad 76 eines nicht dargestellten Antriebes in Pfeilrichtung B angetrieben, umläuft ein Antriebsrad 78, welches mit der Scheibe 72 drehfest verbunden ist, und ist Z-förmig um ein am Arm 64 angeordnetes und ein am C-Profil 62 angeordnetes Umlenkrad 80 bzw. 80' geführt. Diese Z-förmige Führung der Kette 70 ermöglicht das teleskopartige Verschieben des Armes 64 im C-Profil 62 bei immer gespanntem Band 70. Die Rollen 74 des Schwirbels 68 stützen sich abwechslungsweise auf die vodaufenden Kanten der zu stapelnden Druckereiprodukte 14 ab.2 shows a side view of the end of the feed conveyor 26 with the support member 48 and the stacking shaft 46, partially in section. The rollers 40 of the belt conveyors 32 and 34 are rotatably mounted on the rocker 30. The support member 48 has a C-profile 62 in which an arm 64 is guided telescopically. The C-profile 62 is adjustable by means of a holding piece 66, but is non-rotatably attached to the rocker 30. At the free end of the arm 64, a swirl 68 is rotatably mounted. This has e.g. circular disk 72, which can be driven by means of a belt 70, on the periphery of which rollers 74 which are freely rotatably mounted are arranged. The belt 70 is driven by a driven wheel 76 of a drive, not shown, in the direction of arrow B, rotates around a drive wheel 78 which is connected to the disk 72 in a rotationally fixed manner, and is Z-shaped around an arm 64 and a C-profile 62 Deflection wheel 80 or 80 'out. This Z-shaped guide of the chain 70 enables the telescopic displacement of the arm 64 in the C-profile 62 with the belt 70 always tensioned. The rollers 74 of the swirl 68 are alternately supported on the leading edges of the printed products 14 to be stacked.

Die Führungsstangen 52 stützen sich unten auf einer im Gestell 50 um eine vertikale Achse 82 drehbar gelagerten Grundplatte 84 ab. die oberen Enden der Führungsstangen 52 sind mit dem Rahmen 54 miteinander verbunden (vgl. auch Fig. 3).

Der Träger 96 ist mit Stützen 100 versehen, auf welchen eine Stapelplatte 102 befestigt ist. Die Stapelplatte 102 besteht aus zwei Teilplatten, zwischen welchen ein Kettenkanal 104 und am Träger 96 drehbar gelagerte Ausstossrollen 106 angeordnet sind. Der Träger 96 ist mit der Kolbenstange 58 verbunden, welche vom nicht dargestellten, im Gestell 50 angeordneten Hub-Senkantrieb in Pfeilrichtung C aufwärts und abwärts bewegbar ist.The stacking table 56 has a carrier 96, on the end regions of which guides 98 are formed which slide on the guide rods 52. The carrier 96 is provided with supports 100 on which a stacking plate 102 is fastened. The stacking plate 102 consists of two partial plates, between which a chain channel 104 and ejection rollers 106 rotatably mounted on the carrier 96 are arranged. The carrier 96 is connected to the piston rod 58, which can be moved up and down in the direction of arrow C by the lowering / lowering drive arranged in the frame 50.

Der Ausstosser 60 stützt sich mittels weiteren Rollen 115 am Gestell 50 ab und ist mittels einer nicht dargestellten Kette, wie dies in der CH-PS 623.287 und in der entsprechenden US-PS 4,229,134 beschrieben ist, bei abgesenktem Stapeltisch 56 in den Bereich dessen Kettenkanals 104 verschiebbar.The ejector 60 is supported on the frame 50 by means of further rollers 115 and is by means of a chain, not shown, as described in CH-PS 623,287 and in the corresponding US-PS 4,229,134, with the stacking table 56 lowered, in the area of its chain channel 104 slidable.

In der Fig. 3 ist ein Teil des Stapelschachtes 46 von oben vergrössert dargestellt. Der Rahmen 54 stützt sich auf den Führungsstangen 52 ab. An ihm sind, wie weiter oben beschrieben, paarweise Haltenasen 86 angeordnet, von denen nur eine gezeigt ist. An der Haltenase 86 ist ein Schwenkbolzen 116 gelagert, an dem einerends das L-Profil 88 angeordnet ist, und welcher andernends mit einem Ende einer Schraubenfeder 118 verbunden ist, deren anderes Ende an der Haltenase 86 fixiert ist. Am L-Profil 88 ist ein verstellbarer Anschlag 120 angeordnet, welcher infolge der Vorspannung der Schraubenfeder 118 in der Ruhelage am Rahmen 54 aufliegt und die Ruhelage des L-Profiles 88 festlegt. Mittels der Mutter 94, deren Griff 92 in dieser Figur nicht dargestellt ist, ist eine Schiebeplatte 122 mit einem Langloch 124 schiebbar und festklemmbar angeordnet.

An adjustable stop 120 is arranged on the L-profile 88, which rests on the frame 54 due to the pretensioning of the coil spring 118 in the rest position and defines the rest position of the L-profile 88. By means of the nut 94, the handle 92 of which is not shown in this figure, a sliding plate 122 with an elongated hole 124 can be pushed and clamped. The piston-cylinder unit 90 is fastened to the sliding plate 122 approximately parallel to the elongated hole 124.

Ausnehmungen 126 in der Stapelplatte 102 werden von den Anschlagstangen 108 durchstossen, an deren oberen Ende das Anschlagblech 110 befestigt ist. An der Stapelplatte 102 sind weitere Ausnehmungen 128 vorgesehen, welche Platz für die nach unten abstehenden Vibratorzungen 114 freilassen.Recesses 126 in the stacking plate 102 are pierced by the stop rods 108, on the upper end of which the stop plate 110 is fastened. Further recesses 128 are provided on the stacking plate 102, which leave space for the vibrating tongues 114 projecting downward.

In den Figuren 4a bis e ist derselbe Ausschnitt des Zuförderers 26 und der Stapeleinrichtung 12 wie in Fig. 2, jedoch verkleinert und vereinfacht dargestellt Die Bezugszeichen in diesen Figuren stimmen mit den Bezugszeichen der Fig. 2 überein. Sie werden nur noch insoweit erläutert, als es für das Verständnis der Figuren notwendig ist.4a to e show the same section of the feed conveyor 26 and the stacking device 12 as in FIG. 2, but shown in a reduced and simplified form. The reference symbols in these figures correspond to the reference symbols in FIG. 2. They are only explained to the extent that it is necessary for the understanding of the figures.

In der Fig. 4a ist der Stapeltisch 56 in seiner oberen Endlage dargestellt. Der Zuförderer 26 ist mittels des Hubzylinderaggregates 38 (s. Fig. 1) in seine Arbeitsstellung abgesenkt. Dies entspricht derAusgangsstelIung, wenn mit der Stapelbildung begonnen wird, oder wenn, wie das weiter unten erläutert ist, ein Stapel 61' aus dem Stapelschacht 46 geschoben worden ist.4a, the stacking table 56 is shown in its upper end position. The feed conveyor 26 is lowered into its working position by means of the lifting cylinder unit 38 (see FIG. 1). This corresponds to the starting position when the stack formation is started or, as will be explained further below, a stack 61 'has been pushed out of the stack shaft 46.

In der Fig. 4b ist der Stapeltisch 56 teilweise abgesenkt dargestellt. Auf ihm befindet sich ein Teilstapel 61, dessen Falzkanten mittels dem Schwirbel 68 an das rechte Anschlagblech 110 gebracht worden sind. Der Zuförderer 26 ist mittels des Hubzylinderaggregates 38 aus seiner Arbeitsstellung in die Ruhestellung hochgeschwenkt. Die Kolbenstangen der Kolbenzylinderaggregate 90 sind in den Bereich der Ecken der Druckereiprodukte 14 ausgefahren (vgl. auch Fig. 3).4b, the stacking table 56 is shown partially lowered. On it there is a partial stack 61, the fold edges of which have been brought to the right stop plate 110 by means of the swirl 68. The Feed conveyor 26 is pivoted up from its working position into the rest position by means of the lifting cylinder unit 38. The piston rods of the piston-cylinder units 90 are extended in the area of the corners of the printed products 14 (cf. also FIG. 3).

In der Fig. 4c befindet sich der Zuförderer 26 in seiner angehobenen Ruhestellung, der Stapeltisch 56 ist jedoch mittels der Kolbenstange 58 leicht angehoben worden, so dass die Kolben-Zylinderaggregate 90 samt den L-Profilen 88 entgegen der Kraft der Schraubenfeder 118 in horizontale Richtung geschwenkt sind. Der Teilstapel 61 wird gepresst.4c, the feed conveyor 26 is in its raised rest position, but the stacking table 56 has been raised slightly by means of the piston rod 58, so that the piston-cylinder units 90 together with the L-profiles 88 counter to the force of the coil spring 118 in the horizontal direction are pivoted. The partial stack 61 is pressed.

In der Fig. 4d ist der Zuförderer 26 in die Arbeitsstellung abgesenkt. Ein zweiter Teilstapel 61 von Druckereiprodukten 14 ist kreuzweise auf dem ersten Teilstapel 61 aufgelegt. Die Kolbenstangen der Kolben-Zylinderaggregate 90 sind aus dem Bereich der Teilstapel 61 ausgefahren.4d, the feed conveyor 26 is lowered into the working position. A second partial stack 61 of printed products 14 is placed crosswise on the first partial stack 61. The piston rods of the piston-cylinder units 90 are extended from the area of the partial stack 61.

In der Fig. 4e ist der Zuförderer 26 ebenfalls in seiner Arbeitsstellung gezeigt. Der Stapeltisch 56 ist ganz abgesenkt. Auf ihm befindet sich der fertige Stapel 61', welcher aus kreuzweise aufeinandergelegten Teilstapeln 61 besteht. Die Kette 130, welche den Ausstosser 60 betätigt, ist in den Kettenkanal 104 des Stapeltisches 56 eingefahren und stösst den Stapel 61' aus. Dies ist in der Fig. 5 in einer Seitenansicht entsprechend dem Pfeil V in der Fig. 4e nochmals dargestellt. Der Ausstosser 60 bewegt sich zwischen den Vibratorzungen 114 der Vibratoren 112 hindurch ; der Stapel 61' ist hingegen weniger hoch und kann unter den unteren Enden der Vibratorzungen 114 hindurchgeschoben werden. Besonders gut sichtbar ist in dieser Figur die obere Ausnehmung an den Anschlagblechen 110. In dieser Ausnehmung können sich die beiden parallel angeordneten Schwirbel 68 eines Zuförderers 26 berührungsfrei drehen.4e, the feed conveyor 26 is also shown in its working position. The stacking table 56 is completely lowered. On it is the finished stack 61 ', which consists of cross-stacked partial stacks 61. The chain 130, which actuates the ejector 60, has entered the chain channel 104 of the stacking table 56 and ejects the stack 61 '. This is shown again in FIG. 5 in a side view corresponding to the arrow V in FIG. 4e. The ejector 60 moves between the vibrator tongues 114 of the vibrators 112; the stack 61 ', however, is less high and can be pushed under the lower ends of the vibrator tongues 114. The upper recess on the stop plates 110 is particularly clearly visible in this figure. The two parallel swirls 68 of a feed conveyor 26 can rotate in this recess without contact.

Im folgenden wird die Funktionsweise der Vorrichtung zum Stapeln von kontinuierlich in einem Schuppenstrom S anfallenden Druckereiprodukten 14 näher erläutert und damit zusammenhängend wird ein bevorzugtes Verfahren für den Betrieb dieser Vorrichtung dargelegt.The mode of operation of the device for stacking printed products 14 continuously occurring in a shingled stream S is explained in more detail below and, in connection therewith, a preferred method for the operation of this device is presented.

Eine erste Sektion von Druckereiprodukten 14 des Schuppenstromes S wird einer ersten Zubringeinrichtung, beispielsweise 10, durch Lösen der Greifer 18 in der Auslösevorrichtung 20 zugeführt. Der Zuförderer 26 ist in seine Arbeitsstellung abgesenkt, wie dies in Fig. 2 und 4a dargestellt ist. Der Ablagetisch 56 befindet sich in seiner oberen Endstellung. Die vom Zuförderer 26 zum Stapelschacht46 geförderten Druckereiprodukte 14 fallen auf die Stapelplatte 102 und werden von den Rollen 74 des Schwirbels 68, welcher in Pfeilrichtung B angetrieben ist, zur Anschlagplatte 110 beim Schwirbel 68 gedrängt. Der Schwirbel 68 stützt sich dabei auf die aufeinandergestapelten Druckereiprodukte 14 ab, wodurch sich die Wippe 30 im Gegenuhrzeigersinn verschwenkt (siehe insbesondere Fig. 2). Sobald die Wippe 30 am Sensor 49 das Steuersignal auslöst, wird der Stapeltisch 56 soweit abgesenkt, bis sich der Zuförderer 26 wieder in seiner Ausgangslage befindet. Dies wiederholt sich bis genügend Exemplare Druckereiprodukte 14 für einen Teilstapel 61 sich im Stapelschacht 46 befinden. Die Vibratoren 112 wirken beim Stapeln auf die Seitenkanten der Druckereiprodukte 14 ein, so dass diese gegeneinander seitlich ausgerichtet gestapelt werden. Sobald ein Teilstapel 61 gebildet ist, wird die nächste Sektion von Druckereiprodukten 14 des Schuppenstromes S einer weiteren Zubringeinrichtung, beispielsweise 10', und somit zu einer weiteren Stapeleinrichtung 12' geführt, wo auf die oben beschriebene Art und Weise ein weiterer Teilstapel 61 gestapelt wird. Der Zuförderer 26 der ersten Zubringeinrichtung 10 wird in die Ruhestellung hochgeschwenkt (vgl. Fig. 4b) und der Stapeltisch 56 wird mit dem darauf gebildeten ersten Teilstapel 61 soweit abgesenkt, dass die Kolbenstangen der Kolben-Zylinderaggregate 90 eingefahren werden können (siehe auch Fig. 3). Nun wird der erste Teilstapel 62 gepresst, indem der Stapeltisch 56 nach oben verschoben wird bis infolge der Druckkraft die Kolben-Zylinderaggregate 90 entgegen der Kraft der Schraubenfeder 118 in ungefähr horizontale Lage verschwenkt sind. Durch die Vorspannung der Schraubenfeder 118 kann somit die Presskraft auf den Teilstapel 61 vorgewählt werden. Ein nicht dargestellter Sensor erkennt die horizontale Lage der Kolben-Zylinderaggregate 90 und bewirkt ein Abstellen des Anhebens des Stapeltisches 56. Nun wird der Stapelschacht 46 mitsamt dem darin gepressten Teilstapel 61 um die vertikale Achse 82 um 180° gedreht. Anschliessend erfolgt ein geringes Absenken des Stapeltisches 56 bis die Kolben-Zylinderaggregate 90 entlastet sind, so dass die entsprechenden Kolbenstangen aus dem Stapelschacht 46 ausgefahren werden können. Anschliessend wird der Zuförderer 26 wieder in seine Arbeitsstellung nach unten geschwenkt (s. Fig. 4d) und eine nächste Sektion von Druckereiprodukten 14 kann dieser Stapeleinrichtung 12 zugeführt werden. Dies geschieht sobald in einer der anderen Stapeleinrichtungen 12' oder 12" ein ganzer Teilstapel 61 gebildet wurde. Sobald der zweite Teilstapel 61 um 180° versetzt auf dem ersten Teilstapel 61 gebildet ist, erfolgt ein gemeinsames Zusammenpressen und um 180° Drehen, wie dies weiter oben schon anhand eines einzigen Teilstapels 61 beschrieben ist. Dieser Vorgang wiederholt sich, bis eine vorbestimmte Anzahl von Teilstapeln 61 sich im Stapelschacht 46 befindet. Sobald das letzte Druckereiprodukt 14 des obersten Teilstapels 61 dem Stapelschacht 46 zugeführt wurde, bleibt der Zuförderer 26 in seiner Arbeitsstellung, der ganze Stapel 61' kann aber nochmals, wie dies oben angegeben ist, gepresst werden. Anschliessend wird der Stapeltisch 56 ganz abgesenkt (vgl. Fig. 4e und 5), so dass nachfolgend der Stapel 61' mittels des Ausstossers 60 aus dem Stapelschacht 46 zur Weiterverarbeitung ausgestossen werden kann. Nach erneutem Hochfahren des Stapeltisches 56 ist nun die Stapeleinrichtung 12 für die Bildung eines weiteren Stapels 61 bereit.A first section of printed products 14 of the shingled stream S is fed to a first feed device, for example 10, by releasing the grippers 18 in the release device 20. The feed conveyor 26 is lowered into its working position, as shown in FIGS. 2 and 4a. The storage table 56 is in its upper end position. The printed products 14 conveyed from the feed conveyor 26 to the stacking shaft 46 fall onto the stacking plate 102 and are pushed by the rollers 74 of the swirl 68, which is driven in the direction of arrow B, to the stop plate 110 at the swirl 68. The swirl 68 is supported on the stacked printed products 14, as a result of which the rocker 30 pivots counterclockwise (see in particular FIG. 2). As soon as the rocker 30 on the sensor 49 triggers the control signal, the stacking table 56 is lowered until the feed conveyor 26 is again in its starting position. This is repeated until there are enough copies of printed products 14 for a partial stack 61 in the stacking shaft 46. The vibrators 112 act on the side edges of the printed products 14 during stacking, so that they are stacked laterally aligned with one another. As soon as a partial stack 61 is formed, the next section of printed products 14 of the shingled stream S is passed to a further feed device, for example 10 ', and thus to a further stacking device 12', where another partial stack 61 is stacked in the manner described above. The feed conveyor 26 of the first feed device 10 is pivoted up into the rest position (see FIG. 4b) and the stacking table 56 is lowered with the first partial stack 61 formed thereon to such an extent that the piston rods of the piston-cylinder units 90 can be retracted (see also FIG. 3). Now the first partial stack 62 is pressed by moving the stacking table 56 upwards until the piston-cylinder units 90 are pivoted into an approximately horizontal position against the force of the coil spring 118 as a result of the compressive force. By prestressing the helical spring 118, the pressing force on the partial stack 61 can thus be preselected. A sensor, not shown, detects the horizontal position of the piston-cylinder assemblies 90 and causes the stacking table 56 to be raised. Now the stacking shaft 46 together with the partial stack 61 pressed therein is rotated through 180 ° about the vertical axis 82. The stacking table 56 is then lowered slightly until the piston-cylinder assemblies 90 are relieved, so that the corresponding piston rods can be moved out of the stacking shaft 46. The feed conveyor 26 is then pivoted down again into its working position (see FIG. 4d) and a next section of printed products 14 can be fed to this stacking device 12. This happens as soon as an entire partial stack 61 has been formed in one of the other stacking devices 12 'or 12 ". As soon as the second partial stack 61 is formed offset by 180 ° on the first partial stack 61, they are pressed together and rotated by 180 °, as is further described has already been described above with reference to a single partial stack 61. This process is repeated until a predetermined number of partial stacks 61 are in the stacking shaft 46. As soon as the last printed product 14 of the uppermost partial stack 61 has been fed to the stacking shaft 46, the feed conveyor 26 remains in its working position "However, the entire stack 61 'can be pressed again, as indicated above. The stacking table 56 is then lowered completely (see FIGS. 4e and 5), so that the stack 61' is subsequently removed from the stacking shaft by means of the ejector 60 46 can be ejected for further processing Stacking table 56, the stacking device 12 is now ready for the formation of a further stack 61.

Wie schon weiter oben erwähnt, wird, sobald genügend Druckereiprodukte 14 zu einem Teilstapel 61 gestapelt sind, eine nachfolgende Sektion von Druckereiprodukten 14 des Schuppenstromes S einer anderen Stapeleinrichtung 12' und 12" zugeführt. Falls die Zeit für die Bildung eines Teilstapels 61 grösser ist als die Zeit, die für das Pressen des oder der Teilstapel 61 und des Drehen um 1800, sowie das eventuelle Ausstossen eines Stapels 61' benötigt wird, so genügen zwei Zubringereinrichtungen 10,10' und Stapeleinrichtungen 12,12', damit der Transporteur 16 nicht abgestellt werden muss. Falls diese Zeit aber grösser ist als die Zeit, welche für die Bildung eines Teilstapels 61 benötigt wird, so werden drei oder mehr Zubringer- und Stapeleinrichtungen 10,12 in der Vorrichtung angeordnet, so dass abwechslungsweise in allen ein Teilstapel 61 gebildet werden kann, und genügend Zeit den restlichen Stapeleinrichtungen 12 für das Pressen, Drehen und eventuelle Ausstossen von Stapeln 61' zurVerfügung steht, ohne dass dabei der Schuppenstrom S angehalten werden muss.As already mentioned above, as soon as enough printed products 14 have been stacked to form a partial stack 61, a subsequent section of printed products 14 of the shingled stream S is fed to another stacking device 12 'and 12 ". If the time for the formation of a partial stack 61 is greater than the time required for the pressing of the partial stack (s) 61 and the rotation by 180 ° , as well as the eventual ejection of a stack 61 ', two feeder devices 10, 10' and stacking devices 12, 12 'are sufficient so that the conveyor 16 does not However, if this time is greater than the time required for the formation of a partial stack 61, three or more feed and stacking devices 10, 12 are arranged in the device, so that a partial stack 61 is alternately formed in all of them and enough time for the remaining stacking devices 12 for pressing, rotating and possibly ejecting stack n 61 'is available without the shingled stream S having to be stopped.

Es ist zu beachten, dass die Stapeleinrichtungen 12,12', 12", beispielsweise für Umrichtarbeiten bei der Umstellung auf ein anderes Format der Druckereiprodukte 14, aus dem Bereich des Traggestells 8 weggefahren werden kann, was den Zugang zur Zubringereinrichtung 10,10',10", sowie zur Stapeleinrichtung 12,12',12" erleichtert.It should be noted that the stacking devices 12, 12 ', 12 ", for example for conversion work when converting to a different format of the printed products 14, can be moved out of the area of the support frame 8, which gives access to the feeder device 10, 10', 10 ", as well as to the stacking device 12, 12 ', 12".

Die weiter oben beschriebene Vorrichtung weist je drei hintereinander an einem Traggestell 8 angeordnete Zubringereinrichtungen 10,10',10" und Stapeleinrichtungen 12,12',12" auf. Es ist aber auch eine Vorrichtung denkbar, welche nur eine einzige Zubringereinrichtung 10 und Stapeleinrichtung 12 aufweist. Allerdings muss dann beim Drehen des Stapelschachtes bzw. Ausstossen des Stapels die Zuführung von Druckereiprodukten unterbrochen werden.The device described above has three feed devices 10, 10 ', 10 "and stacking devices 12, 12', 12" arranged one behind the other on a support frame 8. However, a device is also conceivable which has only a single feeder device 10 and stacking device 12. However, the supply of printed products must then be interrupted when the stacking shaft is rotated or the stack is ejected.
