Stand der TechnikState of the art

Als Stanzen wird das Schneiden mit in sich geschlossenen geometrischen Zuschnittsformen bezeichnet, die kreisförmig, oval oder mehreckig sowie Phantasieformen aller Art sein können. Auch die in der Druckweiterverarbeitung geübten Praktiken, wie Stanzen mit Locheisen, Eckenabstoßen und Registerstanzen werden zu diesem Bereich gezählt. Die Stanzung erfolgt gegen eine Stanzunterlage oder gegen Stempel, teilweise sind es auch Schervorgänge. Verpackungsmaterialien aus Papier, Karton, Pappe oder Wellpappe werden hauptsächlich im Bogenformat gestanzt. Beim Stanzvorgang können zusätzlich aber auch Rilllinien oder Blindprägungen in den Nutzen eingebracht werden. Dieser komplexe Prozess macht es unabdingbar, die Bogen einzeln zu stanzen. Da es sich bei den Endprodukten um anspruchsvolle Verpackungen hinsichtlich technischer und graphischer Ausführung handelt (etwa Verpackungen für Kosmetik, Zigaretten, Pharmazie, Lebensmittel, etc.), werden besondere Anforderungen nicht nur an die Verpackungsmaterialien selbst gestellt, sondern es sind für optimale Resultate auch Stanzwerkzeuge mit geringsten Toleranzen und äußerst präzise und zuverlässig arbeitende Stanzmaschinen erforderlich. Diesen Ansprüchen wird das Flachbettstanzen am besten gerecht. Dabei werden die gedruckten und auf einer Palette gestapelten Bogen der Stanzmaschine zugeführt. In der Maschine werden in einer Ausrichteinrichtung die zu stanzenden Bogen passgenau ausgerichtet, von einem Greiferwagen übernommen und exakt in der Stanzeinrichtung zwischen einem fest gelagerten Untertisch und einem über einen Kniehebel oder Exzentergetriebe vertikal bewegbaren Obertisch positioniert.As punching the cutting is referred to with closed geometric blank forms that can be circular, oval or polygonal and imaginary shapes of all kinds. Also the practices practiced in print finishing, such as punching with punch, corner punching and register punching are counted to this area. The punching takes place against a punching pad or against stamp, in some cases it is also shearing operations. Packaging materials made of paper, cardboard, cardboard or corrugated board are mainly punched in sheet format. When punching but also creasing lines or blind embossing can be introduced into the benefit. This complex process makes it indispensable to punch the sheets individually. Since the end products are sophisticated packaging in terms of technical and graphic design (such as packaging for cosmetics, cigarettes, pharmacy, food, etc.), special requirements are not only placed on the packaging materials themselves, but are also punching tools for optimum results required with the smallest tolerances and extremely precise and reliable punching machines. Flatbed punching best meets these demands. The printed sheets stacked on a pallet are fed to the punching machine. In the machine, the sheets to be punched are precisely aligned in an alignment device, taken over by a gripper carriage and positioned exactly in the punching device between a fixed undercounter and a vertical over a knee lever or eccentric upper table.

In bekannten Bogenstanz- und Prägemaschinen, die zum Stanzen, Ausbrechen, Prägen und Ablegen von Bögen aus Papier, Pappe und der gleichen eingesetzt werden, ist es bekannt die Bögen mittels Greiferwagen durch die einzelnen Stationen der Maschine zu bewegen. Ein jeweiliger Greiferwagen besitzt eine Greiferbrücke, an der Greifer befestigt sind, die die Bögen an einem vorderen Ende ergreifen. Ein Greiferwagen besitzt weiterhin seitliche Fahrwagen, welche mit endlosen Ketten des Transportsystems verbunden sind und wodurch die Greiferwagen durch die Maschine bewegt werden. Durch diese Art der Bewegung der Bögen durch die Maschine wird ein kontinuierliches Arbeiten in den einzelnen hintereinander angeordneten Stationen der Maschine, insbesondere Stanz-, Ausbrech- und Nutzentrennstation, ermöglicht.In known sheet punching and embossing machines, which are used for punching, breaking, embossing and depositing sheets of paper, cardboard and the same, it is known move the sheets by means of gripper carriage through the individual stations of the machine. A respective gripper carriage has a gripper bridge, to which grippers are fixed, which grasp the arches at a front end. A gripper carriage further has lateral carriages, which are connected to endless chains of the transport system and whereby the gripper carriage to be moved by the machine. By this type of movement of the sheets through the machine, a continuous work in the individual successively arranged stations of the machine, in particular punching, break-away and Nutzentrennstation allows.

Eine derartige Flachbettstanze ist beispielsweise aus der DE 30 44 083 Al bekannt. Die beiden Tische sind mit Schneid- und Rillwerkzeugen bzw. entsprechenden Gegenwerkzeugen bestückt, mit denen aus dem taktweise zwischen die Tischfläche geführten Bögen die Nutzen ausgestanzt und gleichzeitig die zum sauberen Falten notwendigen Rillen eingedrückt werden. In der nachfolgenden Ausbrecheinrichtung wird der Abfall über Ausbrechwerkzeuge maschinell entfernt. Je nach Ausstattung der Maschine können schließlich die gestanzten Nutzen in einer hierfür vorgesehenen Nutzentrenneinrichtung separiert werden.Such a flat bed punch is for example from the DE 30 44 083 Al known. The two tables are equipped with cutting and scoring tools or corresponding counter tools with which punched out of the cyclically guided between the table surface sheets the benefits and at the same time pressed the necessary for clean folding grooves. In the subsequent breakout the waste is removed by machine tools. Depending on the equipment of the machine finally the punched benefits can be separated in a designated Nutzentrenneinrichtung.

Neben den oben beschriebenen Bogenstanz- und -prägemaschinen mit umlaufenden Ketten zum Transport der Greiferwagen geht aus der DE 20 2007 012 349 U1 eine Bogenstanz- und -prägemaschine hervor, deren Greiferwagen an ihren äußeren Enden durch jeweils mindestens einen Linearantrieb angetrieben werden. Der Linearantrieb wird dabei als elektrischer Linearantrieb mit Wechselfeldmotoren ausgebildet. Bei einer derartigen Bogenstanz- und -prägemaschine können verschiedene Greiferwagen zeitgleich mit verschiedenen Geschwindigkeiten bewegt werden.In addition to the sheet punching and embossing machines described above with circulating chains for transporting the gripper carriage goes out of the DE 20 2007 012 349 U1 a sheet punching and embossing machine, the gripper carriage are driven at their outer ends by at least one linear drive. The linear drive is designed as an electric linear drive with alternating field motors. In such a sheet punching and embossing machine different gripper carriages can be moved at the same time at different speeds.

Problematisch an bekannten Bogenstanzmaschinen ist, dass die Leistung der Bogenstanzmaschine durch die Kapazität und Leistung der Auslagestation begrenzt wird. Erfolgt zusätzlich zum Ablegen der gestanzten Bogen noch ein Trennen der Nutzen, so muss die notwendige Zeit dafür zur Verfügung stehen.The problem with known sheet punching machines is that the performance of the sheet punching machine is limited by the capacity and performance of the delivery station. If, in addition to the deposition of the punched sheet still separating the benefits, so the necessary time must be available for it.

Aufgabenstellungtask

Aufgabe der vorliegenden Erfindung ist es daher, eine Bogenverarbeitungsmaschine zu schaffen, bei der die Ausbringung der Bogenverarbeitungsmaschine zumindest in geringerer Weise durch die Bogenablage begrenzt wird.It is therefore an object of the present invention to provide a sheet processing machine in which the output of the sheet processing machine is limited at least to a lesser extent by the sheet deposition.

Gelöst wird diese Aufgabe durch eine Bogenverarbeitungsmaschine mit den Merkmalen von Anspruch 1 als auch durch ein Verfahren zum Ablegen von bogenförmigen Elementen mit den Merkmalen von Anspruch 8.This object is achieved by a sheet processing machine with the features of claim 1 and by a method for depositing arcuate elements with the features of claim 8.

Die erfindungsgemäße Bogenverarbeitungsmaschine zur Bearbeitung von Bogen aus Papier, Pappe und dergleichen besitzt einen Anleger, mindestens eine Bearbeitungsstation, mindestens zwei Auslagestationen und ein Bogentransportsystem mit umlaufenden Greiferwagen. Die bogen werden von dem Bogentransportsystem vom stromaufwärtigen Anleger durch die mindestens eine Bearbeitungsstation hindurch zu den stromabwärtigen Auslegern transportiert. Die umlaufenden Greiferwagen werden durch einzeln ansteuerbare Linearantriebe angetrieben und die Linearantriebe durch ein elektromagnetisches Wanderfeld bewegt. Weiter besitzt die Bogenverarbeitungsmaschine eine Maschinensteuerung zur Steuerung des Anlegers, der mindestens einen Bearbeitungsstation, den mindestens zwei Auslagestationen und dem Bogentransportsystem. In vorteilhafter Weise werden die in der mindestens einen Bearbeitungsstation bearbeiteten Bogen durch das Bogentransportsystem alternierend in den mindestens zwei Auslagestationen abgelegt. Durch den vorteilhaften Einsatz von mindestens zwei Auslagestationen wird die Leistung der Bogenauslage wesentlich erhöht und die Leistung der vorhergehenden Bearbeitungsstation wird weniger beschränkt.The sheet processing machine according to the invention for processing sheets of paper, cardboard and the like has a feeder, at least one processing station, at least two delivery stations and a sheet transport system with rotating gripper carriage. The sheets are transported from the upstream feed through the at least one processing station to the downstream outriggers by the sheet transport system. The revolving gripper carriages are driven by individually controllable linear drives and the linear drives are moved by an electromagnetic traveling field. Furthermore, the sheet processing machine has a machine control for controlling the investor, the at least one processing station, the at least two delivery stations and the sheet transport system. Advantageously, the sheets processed in the at least one processing station are deposited alternately in the at least two delivery stations by the sheet transport system.

In einer vorteilhaften Weiterbildung der erfindungsgemäßen Bogenverarbeitungsmaschine weist diese zwei Auslagestationen aus und zwischen den beiden Auslagestationen ist eine Einheit zum einbringen von Zwischenbogen angeordnet. Die Zwischenbogen dienen dabei dem Stabilisieren der Auslagestapel. Die Einheit zum Einbringen von Zwischenbogen ist beiden Auslagestationen zugeordnet und kann Zwischenbogen in beide Auslagestapel einbringen.In an advantageous development of the sheet processing machine according to the invention, this has two delivery stations and between the two delivery stations, a unit for introducing intermediate sheet is arranged. The interleaf sheets serve to stabilize the delivery stacks. The unit for introducing intermediate sheets is assigned to both delivery stations and can bring interleaf sheets into both delivery stacks.

In einer vorteilhaften Weiterbildung der erfindungsgemäßen Bogenverarbeitungsmaschine besitzt diese zwei Auslagestationen und zwischen den beiden Auslagestationen ist eine Hilfsstapeleinheit mit einem Rechen angeordnet. Der Rechen kann dabei sowohl in die stromaufwärtige als auch in die stromabwärtige Auslagestation verfahren werden. In einer jeweiligen Auslagestation kann der Rechen einen Hilfsstapel aufnehmen. Vorteilhaft an dieser Ausführungsform ist, dass nicht jeder Auslagestation eine separate Hilfsstapeleinheit zugeordnet sein muss und damit Kosten und Bauraum eingespart werden können.In an advantageous development of the sheet processing machine according to the invention, the latter has two delivery stations and an auxiliary stacking unit with a rake is arranged between the two delivery stations. The rake can be moved both in the upstream and in the downstream delivery station. In a respective delivery station, the rake can pick up an auxiliary pile. An advantage of this embodiment is that not every delivery station a separate auxiliary stacking unit must be assigned and thus costs and space can be saved.

In einer vorteilhaften Weiterbildung der erfindungsgemäßen Bogenverarbeitungsmaschine weist mindestens die in Bogentransportrichtung gesehen stromaufwärtige Auslagestation ein Unterwerkzeug und ein insbesondere rolloförmiges oder rollladenförmiges Trennelement auf. Das Trennelement ist zwischen Unterwerkzeug und Bogentransportebene einfahrbar. Das Trennelement wird dann eingefahren, wenn ein Bogen durch die stromaufwärtige Auslagestation weiter bis in die stromabwärtige Auslagestation transportiert wird und stellt sicher, dass der transportierte Bogen durch das Unterwerkzeug der stromaufwärtigen Auslagestation nicht beschädigt wird.In an advantageous development of the sheet processing machine according to the invention, at least the upstream delivery station, viewed in the direction of the sheet transport, has a lower tool and a particularly roll-shaped or roller shutter-shaped separating element. The separating element can be moved in between the lower tool and the sheet transport plane. The divider is then retracted as a sheet is advanced through the upstream delivery station to the downstream delivery station and ensures that the transported sheet is not damaged by the lower tool of the upstream delivery station.

In einer besonders vorteilhaften und daher bevorzugten Ausführungsform ist den mindestens zwei Auslagestationen stromaufwärtig eine Stau- und Beschleunigungsstrecke vorgeordnet.In a particularly advantageous and therefore preferred embodiment, the upstream and downstream at least two Auslagestationen a congestion and acceleration path upstream.

Die Erfindung betrifft auch ein Verfahren zum Ablegen von bogenförmigen Elementen in zwei Auslagestationen in einer Bogenverarbeitungsmaschine. Die Bogenverarbeitungsmaschine besitzt ein Transportsystem mit umlaufenden Greiferwagen, welche durch von einer Maschinensteuerung einzeln ansteuerbaren Linearantrieben bewegt werden. Die bogenförmigen Elemente werden dabei vorteilhafter Weise alternierend in den zwei Auslagestationen abgelegt und die Linearantriebe werden so angesteuert, dass ein jeweils erstes bogenförmiges Element die stromaufwärtige Auslagestation mit hoher Geschwindigkeit durchfährt, der stromabwärtigen Auslagestation zugeführt wird und dort abgelegt wird. Die Linearantriebe werden weiter so angesteuert, dass ein jeweils nachfolgendes bogenförmiges Element der stromaufwärtigen Auslagestation zugeführt und dort abgelegt wird. Die Maschinensteuerung kann weiter die bereits oben aufgeführten Einrichtungen ansteuern: Einheit zum Einbringen von Zwischenbogen, Hilfsstapeleinheit und Trennelement.The invention also relates to a method for depositing arcuate elements in two delivery stations in a sheet processing machine. The sheet processing machine has a transport system with rotating gripper carriage, which are moved by linearly controlled by a machine control linear actuators.

The linear drives are further controlled so that a respective subsequent arcuate element of the upstream delivery station is fed and stored there. The machine control can continue the ones listed above Control devices: unit for inserting intermediate sheet, auxiliary stacking unit and separating element.

In einer vorteilhaften Weiterbildung des erfindungsgemäßen Verfahrens geht den Auslagestationen der Bogenverarbeitungsmaschine eine Stau- und Beschleunigungsstrecke voran und die Linearantriebe werden im Bereich der Stau- und Beschleunigungsstrecke so angesteuert, dass zwei bogenförmige Elemente im Bereich dieser Strecke angesammelt, die bogenförmigen Elemente dann beschleunigt, mit hoher Geschwindigkeit weitertransportiert und den Auslagestationen zugeführt werden. Während die zwei bogenförmigen Elemente in den beiden Auslagestationen abgelegt werden, können bereits zwei weitere nachfolgend bearbeitete bogenförmige Elemente in der Stau- und Beschleunigungsstrecke angesammelt werden. Durch dieses getaktete Ablegen der bogenförmigen Elemente kann die Ausbringungsleistung der Bogenverarbeitungsmaschine in vorteilhafter Weise erhöht werden.In an advantageous development of the method according to the invention, the delivery stations of the sheet processing machine are preceded by a congestion and acceleration section and the linear drives are controlled in the area of the congestion and acceleration section so that two arcuate elements are accumulated in the area of this section, then the arcuate elements are accelerated with a high one Speed further transported and fed to the delivery stations. While the two arcuate elements are deposited in the two delivery stations, two further subsequently processed arcuate elements can already be accumulated in the congestion and acceleration section. By this clocked storing the arcuate elements, the output of the sheet processing machine can be increased in an advantageous manner.

a flatbed sheet punching and / or embossing machine

In Figur 1 ist der prinzipielle Aufbau einer erfindungsgemäßen Bogenstanz- und - prägemaschine 100 zum Stanzen, Ausbrechen und Ablegen von Bögen aus Papier, Pappe und dergleichen dargestellt. Die Stanz- und Prägemaschine 100 besitzt einen Anleger 1, eine Stanzstation 2, eine Ausbrechstation 3 und zwei Auslegestationen 4.1 und 4.2, die von einem gemeinsamen Maschinengehäuse 5 getragen und umschlossen werden.In FIG. 1 the basic structure of a sheet punching and embossing machine 100 according to the invention for punching, breaking and depositing sheets of paper, cardboard and the like is shown. The punching and embossing machine 100 has a feeder 1, a punching station 2, a breaking station 3 and two delivery stations 4.1 and 4.2, which are supported and enclosed by a common machine housing 5.

Die Bögen 6 werden durch einen Anleger 1 von einem Stapel vereinzelt, dem Bogentransportsystem 7 zugeführt und von an Greiferbrücken eines Greiferwagens 8 befestigten Greifern an ihrer Vorderkante ergriffen und in Bogentransportrichtung B intermittierend durch die verschiedenen Stationen 2, 3 und 4.1 und ggfs. 4.2 der Stanz- und Prägemaschine 100 hindurchgezogen.
Das Bogentransportsystem 7 besitzt mehrere Greiferwagen 8, so dass mehrere Bögen 6 gleichzeitig in den verschiedenen Stationen 2, 3 und 4 bearbeitet werden können. Die Greiferwagen 8 werden durch einen elektrischen Linearantrieb mit Wechselfeldmotoren angetrieben.The sheets 6 are separated by a feeder 1 from a stack, fed to the sheet transport system 7 and from on gripper bridges of a gripper carriage. 8 gripped grippers taken at its front edge and pulled in the sheet transport direction B intermittently through the various stations 2, 3 and 4.1 and, if necessary, 4.2 of the punching and embossing machine 100.
The sheet transport system 7 has a plurality of gripper carriages 8, so that a plurality of sheets 6 can be processed simultaneously in the various stations 2, 3 and 4. The gripper carriage 8 are driven by an electric linear drive with alternating field motors.

Die Stanzstation 2 besteht aus einem unteren Tiegel, einem sog. Untertisch 9, und einem oberen Tiegel, einem sog. Obertisch 10. Der Obertisch 10 ist vertikal hin- und herbewegbar gelagert und mit Stanz- und Rillmessern versehen. Der Untertisch 9 ist fest im Maschinengestell gelagert und mit einer Gegenplatte zu den Stanz- und Rillmessern versehen.The punching station 2 consists of a lower crucible, a so-called. Subtable 9, and an upper crucible, a so-called. Obertisch 10. The upper table 10 is mounted vertically moved back and forth and provided with punching and Rillmessern. The lower table 9 is fixedly mounted in the machine frame and provided with a counter plate to the punching and Rillmessern.

Der Greiferwagen 8 transportiert den Bogen 6 von der Stanz- und Prägestation 2 in die nachfolgende Ausbrechstation 3, die mit Ausbrechwerkzeugen ausgestattet ist. In der Ausbrechstation 3 werden mit Hilfe der Ausbrechwerkzeuge die nicht benötigten Abfallstücke aus dem Bogen 6 nach unten herausgestoßen, wodurch die Abfallstücke 11 in einen unter der Station eingeschobenen behälterartigen Wagen 12 fallen.The gripper carriage 8 transports the sheet 6 from the punching and embossing station 2 in the subsequent breaking station 3, which is equipped with breakout tools. In the breaking station 3, the unwanted pieces of waste are pushed out of the sheet 6 downwards with the aid of the stripping tools, whereby the waste pieces 11 fall into a container-like carriage 12 inserted below the station.

Von der Ausbrechstation 3 gelangt der Bogen 6 in den Ausleger 4.1 oder 4.2, wo der Bogen 6 entweder nur einfach abgelegt wird, oder aber gleichzeitig eine Trennung der einzelnen Nutzen erfolgt. Ankommende Bogen 6 werden alternierend in der Auslegestation 4.1 und 4.2 abgelegt. Der Ausleger 4.1 und 4.2 kann auch eine Palette 13 enthalten, auf der die einzelnen Bögen 6 in Form eines Stapels 14 aufgestapelt werden, so dass nach Erreichen einer bestimmten Stapelhöhe die Paletten 14 mit den aufgestapelten Bögen 6 aus dem Bereich der Stanz- und Prägemaschine 100 weggefahren werden können.From the breaking station 3, the sheet 6 enters the boom 4.1 or 4.2, where the sheet 6 is either simply stored, or at the same time there is a separation of the individual benefits. Incoming sheets 6 are stored alternately in the delivery station 4.1 and 4.2. The boom 4.1 and 4.2 may also include a pallet 13, on which the individual sheets 6 are stacked in the form of a stack 14, so that after reaching a certain stack height, the pallets 14 with the stacked sheets 6 from the field of punching and embossing machine 100th can be driven away.

Zwischen der Ausbrechstation 3 und der ersten Auslagestation 4.1 ist eine Stau- und Beschleunigungsstrecke 17 angeordnet. Alternativ kann die Stau- und Beschleunigungsstrecke 17 auch zwischen Ausbrechstation und Auslegern 4.1, 4.2 integriert sein, sodass sich der Abstand zwischen den Stationen nicht erhöht und die Stanzmaschine 100 kompakt baut. Im Bereich dieser Stau- und Beschleunigungsstrecke 17 können Bogen 6 angesammelt, d. h. gestaut, und dann in die Auslagestationen 4.1 und 4.2 beschleunigt weiterbewegt werden. Die erste Auslagestation 4.1 besitzt einen Schutzrollo 20, welcher durch eine Ein- und Ausfahrbewegung a zwischen Bogentransportebene E und das Unterwerkzeug der ersten Auslagestation 4.1 eingefahren werden kann. Ein vom Bogentransportsystem 7 durch die erste Auslagestation 4.1 hindurchbewegter Bogen 6 wird durch den Schutzrollo 20 vor Beschädigungen durch das Unterwerkzeug der ersten Auslagestation 4.1 geschützt. In der in Fig. 1 dargestellten Momentaufnahme wird der Schutzrollo 20 gerade aus seiner Wirkposition herausverfahren, so dass ein sich in der ersten Auslagestation 4.1 befindlicher Bogen 6 auf den Auslagestapel 14 der ersten Auslagestation 4.1 abgelegt werden kann. Zwischen erster Auslagestation 4.1 und zweiter Auslagestation 4.2 befindet sich ein Zwischenbogenmagazin 18, welches durch eine Hubbewegung c höhenveränderlich ist. Von dem Zwischenbogenmagazin 18 können Zwischenbogen sowohl in Bogentransportrichtung B auf den Auslagestapel 14 der zweiten Auslagestation 4.2 als auch entgegen der Bogentransportrichtung B auf den Auslagestapel 14 der ersten Auslagestation 4.1 eingebracht werden. Die Zwischenbogen dienen dabei der Stabilisierung der Auslagestapel 14. Ebenfalls zwischen erster Auslagestation 4.1 und zweiter Auslagestation 4.2 befindet sich ein Rechen einer Hilfsstapeleinheit 19, welcher durch eine Verfahrbewegung b entweder in die erste Auslagestation 4.1 oder in die zweite Auslagestation 4.2 eingefahren werden kann. In eingefahrener Stellung dient der Rechen 19 der Aufnahme eines Hilfsstapels und ermöglicht dadurch den Non-Stop-Betrieb der beiden Auslagestationen 4.1 und 4.2. Der Aufbau von Hilfsstapeleinheiten mit Rechen ist dem Fachmann allgemein bekannt und geht beispielsweise aus der DE 195 16 023 A1 hervor.Between the breaking station 3 and the first delivery station 4.1 a congestion and acceleration section 17 is arranged. Alternatively, the traffic jam and acceleration section 17 can also be integrated between stripping station and outriggers 4.1, 4.2, so that the distance between the stations does not increase and the Punching machine 100 compact builds. In the area of this congestion and acceleration section 17, sheets 6 can be accumulated, ie jammed, and then further accelerated into the delivery stations 4.1 and 4.2. The first display station 4.1 has a protective roller blind 20, which can be retracted by a retraction and extension movement a between the sheet transport plane E and the lower tool of the first display station 4.1. A sheet 6 moved by the sheet transport system 7 through the first delivery station 4.1 is protected by the protective roller blind 20 from being damaged by the lower tool of the first delivery station 4.1. In the in Fig. 1 shown snapshot of the protective roller 20 just out of its operative position, so that a located in the first delivery station 4.1 sheet 6 can be placed on the delivery stack 14 of the first delivery station 4.1. Between first delivery station 4.1 and second delivery station 4.2 is an intermediate sheet magazine 18 which is höhenveränderlich by a stroke c. Of the intermediate sheet magazine 18 intermediate sheets can be introduced both in the sheet transport direction B on the delivery stack 14 of the second delivery station 4.2 and against the sheet transport direction B on the delivery stack 14 of the first delivery station 4.1. The intermediate sheets serve to stabilize the delivery stacks 14. Also located between the first delivery station 4.1 and second delivery station 4.2 is a rake of an auxiliary stacking unit 19, which can be moved by a movement b either in the first delivery station 4.1 or in the second delivery station 4.2. In the retracted position, the rake 19 serves to receive an auxiliary stack and thereby enables the non-stop operation of the two delivery stations 4.1 and 4.2. The construction of auxiliary stacking units with rake is well known to the skilled person and is for example from the DE 195 16 023 A1 out.
