Abstract

The stacking process involves taking the printed products (28) to a pre-stacking shaft (20) with an input from a device (12) supplying the added sheets (14). There is a shaft (36) below this which can turn 180degrees on its axis (38) to take a part stack (34) from the pre-stacking shaft. Each part stack can be formed in the pre-stacking device on an added sheet, so that in the complete stack (54), the part stacks are separated from each other by it.

Description

Die vorliegende Erfindung betrifft ein Verfahren und eine Einrichtung zum Herstellen von mit einem Zusatzblatt versehenen Stapeln von Druckereiprodukten mit den Merkmalen des Oberbegriffs des Patentanspruchs 1 bzw. 6.The present invention relates to a method and a device for producing stacks of printed products provided with an additional sheet having the features of the preamble of patent claims 1 and 6, respectively.

Ein Verfahren und eine Einrichtung dieser Art sind beispielsweise aus der CH-A-667 065 und der entsprechenden US-A-4,565,130 bekannt.A method and apparatus of this kind are known, for example, from CH-A-667 065 and corresponding US-A-4,565,130.

Unterhalb eines Vorstapelschachtes, in welchem die von oben zugeführten Druckereiprodukte zu Vorstapeln gestapelt werden, befindet sich ein Schacht, welchem nach jeweiligem Drehen um 180° die Vorstapel gegeneinander verdreht abgegeben werden. Die in einer Vorrichtung zum Bereitstellen loser und bedruckter Deckblätter aufbereiteten Deckblätter werden mittels eines Deckblattförderers in den Schacht eingeführt, so dass jeweils ein bedrucktes Deckblatt auf den Fertigstapel oder unterhalb des im Schacht aufzubauenden Stapels zu liegen kommt.Below a Vorstapelschachtes, in which the supplied from above printed products are stacked to pre-stacking, there is a shaft which after each rotation by 180 °, the pre-stack against each other are rotated rotated. The cover sheets processed in a device for providing loose and printed cover sheets are introduced into the shaft by means of a cover sheet conveyor so that in each case a printed cover sheet comes to rest on the finished stack or below the stack to be built up in the shaft.

Die EP-A-0 968 947 und die entsprechende US-A-6,241,233 offenbaren eine Vorrichtung, bei welcher gleichzeitig mit dem Ausstossen eines Fertigstapels aus dem Schacht ein Deckblatt in den Schacht hineingezogen wird, auf welchem der nächste Stapel zu liegen kommt.EP-A-0 968 947 and corresponding US-A-6,241,233 disclose an apparatus in which, at the same time as the ejection of a finished stack from the shaft, a cover sheet is drawn into the shaft upon which the next stack comes to rest.

Bei einem aus der EP-A-0 894 721 bekannten Verfahren und bei einer entsprechenden Vorrichtung wird jeweils der Fertigstapel aus aufeinander um 180° verdreht abgelegten Teilstapeln mit Hilfe eines Schiebers aus dem Schacht ausgestossen und einem Drucker und Ausleger zugeführt, mit Hilfe derer der Stapel mit einem Deckblatt bestückt wird. Wiederum mit Hilfe eines Schiebers wird der bestückte Stapel in eine Umreifungsposition gefördert und umreift.In a method known from EP-A-0 894 721 and a corresponding device, the Prefabricated stack of mutually rotated by 180 ° deposited part stacks using a slide ejected from the shaft and fed to a printer and boom, by means of which the stack is equipped with a cover sheet. Again with the help of a slider, the loaded stack is conveyed to a strapping position and strapped.

Ein weiteres Verfahren und eine weitere Vorrichtung zur Schutzumhüllung von Stapeln von Druckereierzeugnissen sind aus der WO-A-00/34127 bekannt. Stapel von Druckereiprodukten die je eine durch eine erhöhte Dicke ausgezeichnete Kante aufweisen, werden derart umhüllt, dass diejenigen Stapelseiten, in denen die ausgezeichneten Kanten angeordnet sind, von der Umhüllung ganz bedeckt und damit gut geschützt sind. Da die genannten Stapel in einer Richtung quer zu den ausgezeichneten Kanten wenig stabil sind, werden die Stapel parallel zu den ausgezeichneten Kanten aus einem Stapelschacht, in dem sie gebildet werden, ausgestossen direkt zwischen die Gabeln eines Gabelpaares. Der Stapel wird zwischen den Gabeln gepresst und das Gabelpaar zusammen mit dem gepressten Stapel wird durch einen Vorhang eines Umhüllungsmaterials geführt. Das Umhüllungsmaterial wird dann um das Gabelpaar und um den Stapel geschlossen und der umhüllte Stapel wird anschliessend an die Erstellung der Umhüllung durch eine Relativbewegung zwischen Gabelpaar und Stapel vom Gabelpaar getrennt und weggefördert. Eine Pressgabel kann mit einem beweglichen Fach für ein in der Ausstossposition auf einen Stapel aufzubringenden Deckblatt oder zum Aufbringen eines anderen flachen Produktes ausgerüstet sein. Bei der Trennung vom umhüllten Stapel und Gabelpaar wird das Fach mit dem Gabelpaar aus der Umhüllung gezogen und bleibt das Deckblatt auf dem Stapel liegen.Another method and apparatus for protecting wrapping of printed products are known from WO-A-00/34127. Stacks of printed products each having an edge which is distinguished by an increased thickness are enveloped in such a way that those stack sides in which the marked edges are arranged are completely covered by the covering and thus well protected. Since the said stacks are less stable in a direction transverse to the excellent edges, the stacks parallel to the excellent edges are ejected from a stacking shaft in which they are formed directly between the forks of a fork pair. The stack is pressed between the forks and the fork pair together with the pressed stack is passed through a curtain of wrapping material. The wrapping material is then closed around the fork pair and around the stack, and the wrapped stack is then separated from the pair of forks by a relative movement between the fork pair and the stack and conveyed away. A press fork may be equipped with a movable tray for a cover sheet to be applied to a stack in the eject position, or for applying another flat product. When separating from the wrapped stack and fork pair the tray is pulled out of the wrapper with the fork pair and the wrapper remains on the stack.

Die EP-A-0 586 802 und die entsprechende US-A-5,370,382 offenbaren eine Vorrichtung zum Bilden von Stapeln aus gefalteten Druckereiprodukten, bei welcher ein Vorstapelschacht unten mittels Schieberplatten geschlossen ist und oberhalb der Schieberplatten Zwischenbodenelemente in den Stapelschacht einschiebbar sind, auf welchem zu Beginn einer Teilstapelbildung die zugeführten Druckereiprodukte aufeinander abgelegt werden. Sobald eine bestimmte Anzahl Druckereiprodukte gestapelt ist, werden die Zwischenbodenelemente aus dem Stapelschacht herausgezogen, wodurch die gestapelten Druckereiprodukte auf die Schieberplatten fallen und der Teilstapel unter Zuführung weiterer Druckereiprodukte fertiggestellt wird. Der fertige Teilstapel wird dann durch Auseinanderfahren der Schieberplatten auf einen heb- und senkbaren Schachtboden abgesetzt.EP-A-0 586 802 and corresponding US-A-5,370,382 disclose an apparatus for forming stacks of folded printed products in which a pre-stacking shaft is closed at the bottom by slide plates and above the slide plates intermediate tray elements are insertable into the stacking tray on which Beginning of a partial stack formation the supplied printed products are stored on each other. As soon as a certain number of printed products are stacked, the intermediate floor elements are pulled out of the stacking shaft, whereby the stacked printed products fall on the slide plates and the partial stack is completed while supplying further printed products. The finished part stack is then discontinued by moving apart the slide plates on a raised and lowered shaft bottom.

Gemäss den bekannten Verfahren und mit den bekannten Einrichtungen werden die empfängerspezifische Anzahl von Druckereiprodukten zu einem Fertigstapel gestapelt und mit einem Deckblatt versehen, dann mit einer Folie umhüllt oder mittels eines Bandes umbunden. Sind mehreren Empfängern nacheinander eine kleinere Anzahl Druckereiprodukte auszuliefern, werden die Fertigstapel mit der entsprechend geringen Anzahl Druckereiprodukte zusammengebracht, aufeinandergestapelt und für den Transport und das Handling nochmals umhüllt oder gebunden. Dies bedingt Vorrichtungen zum Zwischenlagern, aufeinander Ablegen und Umhüllen oder Binden der Fertigstapel.According to the known methods and with the known devices, the receiver-specific number of printed products are stacked into a finished stack and provided with a cover sheet, then wrapped with a film or bound by means of a tape. If several receivers successively deliver a smaller number of printed products, the finished stacks are brought together with the correspondingly small number of printed products, stacked and wrapped again or tied for transport and handling. This requires devices for temporary storage, stacking one another and wrapping or binding the finished stack.

Es ist deshalb eine Aufgabe der vorliegenden Erfindung, das bekannte Verfahren und die gattungsgemässe Einrichtung derart weiterzubilden, dass auf die genannten zusätzlichen Vorrichtungen verzichtet werden kann.It is therefore an object of the present invention, the known method and the generic device in such a way that can be dispensed with said additional devices.

Diese Aufgabe wird mit einem gattungsgemässen Verfahren und mit einer gattungsgemässen Einrichtung gelöst, welches bzw. welche die Merkmale im Kennzeichen des Anspruchs 1 bzw. 6 aufweist.This object is achieved by a generic method and with a generic device, which or which has the features in the characterizing part of claim 1 and 6 respectively.

Erfindungsgemäss wird zwischen zwei benachbarte Teilstapel ein Zusatzblatt angeordnet. Dabei kann es sich zum Trennen von aufeinanderliegenden Teilstapeln, um ein Trennblatt handeln, das beispielsweise farbig und unbedruckt oder auch bedruckt ist. In bevorzugter Weise geschieht dies, indem jeweis ein Zusatzblatt in einen Vorstapelschacht eingeführt wird, in welchem die Druckereiprodukte zu den Teilstapeln gestapelt werden. Da nun nicht mehr jeder empfangsspezifische Fertigstapel für sich umhüllt, umschnürt oder umreift werden muss, steht für die Verpackung, d.h. Umhüllen, Umschnüren oder Umreifen und den Abtransport der Fertigstapel eine grosse Zykluszeit zur Verfügung.According to the invention, an additional sheet is arranged between two adjacent part stacks. It may be for separating stacked sub-stacks, a release sheet, which is for example colored and unprinted or printed. Preferably, this is done by jeweis an additional sheet is inserted into a Vorstapelschacht in which the printed products are stacked to the sub-stacks. Since it is no longer necessary for each reception-specific ready-made stack to be wrapped, tied or strapped on its own, the packaging, i. Enveloping, strapping or strapping and the removal of the finished stack a large cycle time available.

Die Stapelvorrichtung 10 weist eine Vorstapeleinrichtung 18 auf, deren Vorstapelschacht 20 auf allen vier Seiten mittels Führungsprofilen 22 und unten von zwei in den Vorstapelschacht 20 einfahrbaren und aus diesem ausfahrbaren Schieberplatten 24 begrenzt ist. In einem Abstand oberhalb der Schieberplatten 24 sind in den Vorstapelschacht 20, beispielsweise gabelartige Zwischenbodenelemente 26 einfahrbar und daraus wieder ausfahrbar. Der Aufbau und die Funktionsweise dieser Vorstapeleinrichtung 18 und deren Zusammenwirken mit einem darunter angeordneten, drehbaren Schacht sind aus der EP-A-0 586 802 und der entsprechenden US-A-5,370,382 bekannt.The stacking device 10 has a pre-stacking device 18, the pre-stacking shaft 20 is limited on all four sides by means of guide profiles 22 and bottom of two retractable into the pre-stacking shaft 20 and extendable from this slide plates 24. At a distance above the slide plates 24, for example, fork-like intermediate floor elements 26 are retractable into the pre-stacking shaft 20 and out of it again extendable. The structure and operation of this pre-stacking device 18 and its interaction with a rotatable shaft located thereunder are known from EP-A-0 586 802 and corresponding US-A-5,370,382.

Der Vorstapeleinrichtung 18 sind Druckereiprodukte 28, im vorliegenden Fall gefaltete Zeitungen, in Schuppenformation mittels eines als Bandförderer ausgebildeten Zuförderers 30 derart zuführbar, dass der Vorstapelschacht 20 von oben beschickt wird.The pre-stacking device 18 are printed products 28, in the present case folded newspapers, fed in dandruff formation by means of a feed conveyor 30 designed as a belt conveyor such that the pre-stacking shaft 20 is fed from above.

Weiter ist der Vorstapeleinrichtung 18 die Vorrichtung 12 zum Zuführen der Zusatzblätter 14 derart zugeordnet, dass der ein Förderrollenpaar für die Deckblätter 14 aufweisende Auslass 32 von der Seite her unmittelbar oberhalb der Schieberplatten 24 unten in den Vorstapelschacht 20 einmündet. In der Fig. 1 liegt auf den in den Vorstapelschacht 20 eingefahrenen Schieberplatten 24 ein bedrucktes Zusatzblatt 14 - ein sogenanntes Deckblatt - auf, auf welchem sich ein Teilstapel 34 aus einer bestimmten Anzahl, im vorliegenden Fall fünf, Druckereiprodukten 28 befindet. Wie mit Pfeilen angedeutet, werden die Zwischenbodenelemente 26 in den Vorstapelschacht 20 eingefahren, um die nächsten mittels des Zuförderers 30 zugeführten Druckereiprodukte 28 auf diesen zu stapeln, bis der Teilstapel 34 durch Ausfahren der Schieberplatten 24 aus dem Vorstapelschacht 20 abgegeben worden ist, die Schieberplatten 24 wieder in den Vorstapelschacht 20 eingefahren und gegebenenfalls ein neues Zusatzblatt 14 für den nächsten Teilstapel 34 in den Vorstapelschacht 20 eingeführt worden ist.Furthermore, the pre-stacking device 18 is associated with the device 12 for feeding the additional sheets 14 such that the outlet 32 having a conveyor roller pair for the cover sheets 14 opens from the side immediately above the slide plates 24 into the pre-stacking shaft 20. In FIG. 1, a printed additional sheet 14 - a so-called cover sheet - rests on the slide plates 24 inserted in the pre-stacking shaft 20, on which a partial stack 34 of a certain number, in the present case five, printed products 28 is located. As indicated by arrows, the intermediate floor elements 26 are retracted into the pre-stacking shaft 20 in order to stack the next printed products 28 supplied thereto by the feed conveyor 30 until the partial stack 34 has been discharged from the pre-stacking shaft 20 by extending the slide plates 24, the slide plates 24 retracted again into the Vorstapelschacht 20 and optionally a new additional sheet 14 has been introduced for the next part of stack 34 in the pre-stacking shaft 20.

Unterhalb der Vorstapeleinrichtung 18 weist die Stapelvorrichtung 10 einen Schacht 36 auf, der um eine vertikale zentrale Drehachse 38 drehbar und dessen Schachtboden 40 mittels eines entsprechenden Antriebs heb- und senkbar ist. Nach der Übernahme jeweils eines Teilstapels 34 kann der Schacht 36 um 180° um die Drehachse 38 gedreht werden, so dass die in diesem aufeinander abgelegten Teilstapel 34 jeweils um 180° relativ zueinander gedreht sind. Um die Fallhöhe der Teilstapel 34 beim Herausziehen der Schieberplatten 24 aus dem Vorstapelschacht 20 zu verringern und damit eine hohe Qualität der Stapelung zu erzielen, wird jeweils der Schachtboden 40 soweit angehoben, bis er bzw. das oberste der auf ihm gestapelten Druckereiprodukte 28 sich mit geringem Abstand unterhalb der Schieberplatten 24 befindet. Beim anschliessenden Absenken des Schachtbodens 40 werden die Schieberplatten 24 wieder in den Vorstapelschacht 20 eingefahren, sobald sich der vollständige abgegebene Teilstapel 34 im Schacht 36 befindet.Below the pre-stacking device 18, the stacking device 10 has a shaft 36 which is rotatable about a vertical central axis of rotation 38 and the shaft bottom 40 by means of a corresponding drive can be raised and lowered. After each take over a partial stack 34, the shaft 36 can be rotated by 180 ° about the axis of rotation 38, so that in this successive stacked part 34 are each rotated by 180 ° relative to each other. To the Fall height of the sub-stacks 34 when pulling the slide plates 24 from the pre-stacking shaft 20 to reduce and thus achieve a high quality of stacking, the shaft bottom 40 is raised so far until he or the top of the stacked on him printed products 28 at a short distance below the slide plates 24 is located. During the subsequent lowering of the shaft bottom 40, the slide plates 24 are retracted again into the pre-stacking shaft 20 as soon as the complete discharged partial stack 34 is in the shaft 36.

Im Schacht 14 befindet sich ein Fertigstapel 54 aus fünf Teilstapeln 34, wobei zwischen den Teilstapeln 34 je ein Zusatzblatt 14 angeordnet ist. Bei diesen Zusatzblättern 14 handelt es sich um vorzugsweise farbige, gegebenenfalls unbedruckte Trennblätter. Mittels dieser Trennblätter ist die Trennung der Teilstapel 34 besonders gut erkennbar.In the shaft 14 is a finished stack 54 of five sub-stacks 34, wherein between the sub-stacks 34 depending an additional sheet 14 is arranged. These additional sheets 14 are preferably colored, optionally unprinted release sheets. By means of these separator sheets, the separation of the partial stack 34 is particularly easy to recognize.

Der Schacht 36 ist an seinen vier Ecken durch je ein in vertikaler Richtung verlaufendes Winkelprofil 42, 42' begrenzt. Die in einer Ausstossrichtung A gesehen am stromaufwärts liegenden Ende des Schachtes 36 angeordneten Winkelprofile sind mit 42, die am stromabwärts liegenden Ende angeordneten Winkelprofile mit 42' bezeichnet. Die Winkelprofile 42 sind je an einer oberen und an einer unteren endlosen Kette 44 befestigt, welche in Ausstossrichtung A gesehen am stromaufwärts gelegenen und am stromabwärts gelegenen Ende des Schachtes 36 um entsprechende Kettenräder 46 geführt ist. Entsprechend sind die Winkelprofile 42' je an einer weiteren oberen und einer weiteren unteren Kette 48 angeordnet, welche um weitere Kettenräder 50 geführt sind, welche gleichachsig zu den Kettenrädern 46 gelagert sind. Mittels eines Antriebsmotors 52 sind die einander gegenüberliegenden Winkelprofile 42 synchron bewegbar durch den gleichzeitigen Antrieb der entsprechenden Ketten 44, wobei der Antriebsmotor 52 über ein Umkehrgetriebe mit den auf der anderen Seite des Schachtes 36 angeordneten Ketten 44 verbunden ist. In entsprechender Art und Weise sind die Winkelprofile 42' synchron mittels eines weiteren, nicht gezeigten Antriebsmotors antreibbar.The shaft 36 is bounded at its four corners by a respective extending in the vertical direction angle section 42, 42 '. The arranged in an ejection direction A at the upstream end of the shaft 36 arranged angle profiles are 42, the arranged at the downstream end angle profiles 42 '. The angle profiles 42 are each attached to an upper and a lower endless chain 44, which is seen in the ejection direction A at the upstream and at the downstream end of the shaft 36 is guided around corresponding sprockets 46. Correspondingly, the angle profiles 42 'are each arranged on a further upper and a further lower chain 48, which are guided around further sprockets 50, which are mounted coaxially to the sprockets 46. By means of a drive motor 52, the opposing angle profiles 42 are synchronously movable by the simultaneous drive of the corresponding chains 44, wherein the drive motor 52 is connected via a reverse gear with the arranged on the other side of the shaft 36 chains 44. In a corresponding manner, the angle profiles 42 'can be driven synchronously by means of a further drive motor, not shown.

In den Fig. 1 und 2 sind die Winkelprofile 42, 42' mittels der Antriebsmotoren 52 in eine Position verbracht, in welcher sie den Schacht 36 derart begrenzen, dass zwischen ihnen und den zu stapelnden bzw. bereits gestapelten Druckereiprodukten 28 ein Spalt vorhanden ist, um ein Anheben und Absenken mittels des Schachtbodens 40 ohne Verletzung der darauf angeordneten Druckereiprodukte 28 zu ermöglichen. Jedoch befinden sich die Winkelprofile 42, 42' in einer derartigen Lage, dass die Druckereiprodukte 28 keinesfalls aus dem Schacht 36 herausgleiten können.In FIGS. 1 and 2, the angle profiles 42, 42 'are moved by means of the drive motors 52 into a position in which they delimit the slot 36 in such a way that a gap exists between them and the printed products 28 to be stacked or already stacked, to allow lifting and lowering by means of the shaft bottom 40 without damaging the printed products 28 arranged thereon. However, the angle profiles 42, 42 'are in such a position that the printed products 28 can not slip out of the shaft 36 at all.

Zum Drehen des Schachtes 36 werden die auf den beiden Seiten des Schachtes 36 angeordneten Winkelprofile 42, 42' mittels der Antriebsmotoren 52 jeweils aufeinander zu bewegt, bis sie an den gestapelten Druckereiprodukten 28 anliegen. Dadurch ist ein sehr schnelles Drehen des Schachtes 36 gewährleistet, ohne dass die Gefahr vorhanden ist, dass im Schacht 36 vorhandene Druckereiprodukte 28 verschoben oder verdreht werden.To rotate the shaft 36, the angle profiles 42, 42 'arranged on the two sides of the shaft 36 are each moved toward one another by means of the drive motors 52 until they rest on the stacked printed products 28. As a result, a very fast rotation of the shaft 36 is ensured, without the danger that in the shaft 36 existing printed products 28 are moved or rotated.

Zum Ausstossen eines Fertigstapels 54 in Ausstossrichtung A aus dem Schacht 36 und gleichzeitigen Zuführen zur Umreifungsstation 16 werden vorerst die weiteren Winkelprofile 42' oder diese zusammen mit den Winkelprofilen 42 in Ausstossrichtung A bewegt, wodurch einerseits sich die Winkelprofile 42' aus der Bewegungsbahn des Fertigstapels 54 hinaus um die zugeordneten weiteren Kettenräder 50 in den Bereich des aussenliegenden Rücktrums der weiteren Ketten 48 bewegen und andererseits die Winkelprofile 42' den Fertigstapel 54 aus dem Schacht 36 ausstossen. Sobald der Ausstossvorgang beendet ist, werden die Winkelprofile 42 und 42' mittels der Antriebsmotoren 52 wieder in die in den Fig. 1 und 2 gezeigte Stellung verbracht.For ejecting a finished stack 54 in the ejection direction A from the shaft 36 and simultaneous feeding to Umreifungsstation 16, the other angle profiles 42 'or these are initially moved together with the angle profiles 42 in the ejection direction A, whereby on the one hand, the angle profiles 42' from the path of movement of the finished stack 54th also move around the associated further sprockets 50 in the region of the outer return strand of the other chains 48 and on the other hand, the angle sections 42 ' eject the finished stack 54 from the shaft 36. Once the ejection process is completed, the angle profiles 42 and 42 'are returned by means of the drive motors 52 in the position shown in Figs. 1 and 2.

Fig. 3 zeigt einen im Schacht 36 gebildeten Fertigstapel 54 während des Ausstossens in Ausstossrichtung A mittels der Winkelprofile 42. Die hier nicht dargestellten Winkelprofile 42' befinden sich ausserhalb der Bewegungsbahn des Fertigstapels 54 im Bereich des Rücktrums der entsprechenden weiteren Ketten 48. Ein vorgängig gebildeter ausgestossener Fertigstapel 54 wurde in der Umreifungsstation 16 mittels eines Bandes 56 umreift und befindet sich zum Wegtransport auf einem als Bandförderer ausgebildeten Wegförderer 58. Wie strichpunktiert angedeutet, kann in der Umreifungsstation 16 der Fertigstapel 54 vor dem Umreifen mit einem Band 56 in bekannter Art und Weise mit einer Folie 60 umhüllt werden. In diesem Fall ist die Umreifungsstation 16 als Umhüllungs- und Umreifungsstation ausgebildet, oder ist der Umreifungsstation 16 eine Umhüllungsstation vorgeschaltet, welcher die Fertigstapel 54 von der Stapelvorrichtung 10 herkommend zuerst zugeführt werden. Dazu geeignete Vorrichtungen sind aus dem Stand der Technik bekannt.FIG. 3 shows a finished stack 54 formed in the shaft 36 during the ejection in the ejection direction A by means of the angle profiles 42. The angle profiles 42 ', not shown here, are located outside the path of movement of the finished stack 54 in the area of the return strand of the corresponding further chains 48 ejected finished stack 54 was strapped in the strapping station 16 by means of a belt 56 and is located for transporting away on a trained as a belt conveyor elevator 58. As indicated by dash-dotted lines, in the strapping 16 of the finished stack 54 before strapping with a belt 56 in a known manner be wrapped with a film 60. In this case, the strapping station 16 is designed as a wrapping and strapping station, or the strapping station 16 is preceded by a wrapping station, to which the finished stacks 54 coming from the stacking device 10 are fed first. For this purpose, suitable devices are known from the prior art.

Der Vollständigkeit halber sei erwähnt, dass der Schachtboden 40 kreuzförmig ausgebildet ist, wie dies den Fig. 1 und 2 entnehmbar ist. Dies ermöglicht einerseits das Stapeln von Druckereiprodukten 28 mit einem Format, das kleiner ist als die Länge des Schachtbodens 40 in Ausstossrichtung A gemessen, da sich die Profile 42 und 42' an den in Ausstossrichtung A verlaufenden Armen des Schachtbodens 40 vorbeibewegen können. Gleichzeitig ist jedoch die Stabilität für die gestapelten Druckereiprodukte 28 durch die rechtwinklig zur Ausstossrichtung A verlaufenden Arme des Schachtbodens 40 gewährleistet. Andererseits kann das Ausstossen eines Fertigstapels 54 bereits während des Absenkens des Schachtbodens 40 in seine untere Endlage beginnen.For completeness, it should be mentioned that the shaft bottom 40 is formed in a cross shape, as shown in FIGS. 1 and 2 can be removed. On the one hand, this enables the stacking of printed products 28 having a format that is smaller than the length of the shaft bottom 40 measured in the ejection direction A, since the profiles 42 and 42 'can move past the arms of the shaft bottom 40 in the ejection direction A. At the same time, however, the stability for the stacked printed products 28 by the perpendicular to the ejection direction A extending arms of Well bottom 40 guaranteed. On the other hand, the ejection of a finished stack 54 can already begin during the lowering of the shaft bottom 40 in its lower end position.

Zu dem in den Fig. 1 und 2 gezeigten Zeitpunkt ist ein Fertigstapel im Schacht 36 gebildet, dessen je eine Lage bildende Teilstapel 34 durch je ein Zusatzblatt 14 voneinander getrennt sind. Der Fertigstapel 54 wird in Ausstossrichtung A aus dem Schacht 36 ausgestossen und der Umreifungsstation 16 zugeführt, während in der Vorstapeleinrichtung 18 bereits der erste Teilstapel 34 des nächsten zu bildenden Fertigstapels 54 gebildet worden ist. Dieser Teilstapel 34 liegt auf einem Deckblatt - Zusatzblatt - 14 auf, welches in den Vorstapelschacht 20 durch den Auslass 32 zugeführt worden ist. Die Zwischenbodenelemente 26 werden in den Vorstapelschacht 20 eingefahren, um darauf die nächstfolgenden mittels des Zuförderers 30 angelieferten Druckereiprodukte 28 zu stapeln. Sobald der Fertigstapel 54 aus dem Schacht 36 ausgestossen ist, wird der Schachtboden 40 bis unter die Schieberplatten 24 angehoben, worauf diese aus dem Vorstapelschacht 20 herausgezogen werden und der darauf liegende Teilstapel 34 mit dem Zusatzblatt 14 auf den Schachtboden 40 zu liegen kommt. Nach dem Einfahren der Schieberplatten 24 wird ein neues Zusatzblatt 14 - ein Trennblatt - zugeführt und werden die Zwischenbodenelemente 26 aus dem Vorstapelschacht 20 ausgefahren, um dann den auf dem Zusatzblatt 14 liegenden Teilstapel 34 auf den Schieberplatten 24 zu vervollständigen. Währenddessen wird der Schacht 36 um die Drehachse 38 um 180° gedreht und der Schachtboden 40 so weit angehoben, dass das oberste Produkt des auf ihm aufliegenden Teilstapels 34 mit geringem Abstand unterhalb der Schieberplatten 24 sich befindet, um dann beim Herausziehen der Schieberplatten 24 aus dem Vorstapelschacht 20 den nächsten Teilstapel zu übernehmen. Hier weist auch der unterste Teilstapel 34 des zukünftigen Fertigstapels 54 ein Zusatzblatt 14 - das Deckblatt - auf; die Teilstapel 34 sind mittels eines Trennblatts voneinander getrennt und weisen die entsprechende Anzahl Druckereiprodukte 28 auf.At the time shown in FIGS. 1 and 2, a finished stack in the shaft 36 is formed, each of which a layer forming part stack 34 are separated by a respective additional sheet 14 from each other. The finished stack 54 is ejected in the ejection direction A from the shaft 36 and the Umreifungsstation 16 fed, while in the Vorstapeleinrichtung 18 already the first part of stack 34 of the next finished stack 54 to be formed has been formed. This partial stack 34 rests on a cover sheet - additional sheet - 14, which has been fed into the pre-stacking shaft 20 through the outlet 32. The intermediate floor elements 26 are moved into the pre-stacking shaft 20 in order to stack thereon the next following printed products 28 delivered by the feeder 30. As soon as the finished stack 54 has been ejected from the shaft 36, the shaft bottom 40 is raised below the slide plates 24, whereupon these are pulled out of the pre-stacking shaft 20 and the partial stack 34 resting thereon with the additional blade 14 comes to rest on the shaft bottom 40. After retraction of the slide plates 24, a new additional sheet 14 - a separator sheet - fed and the intermediate floor elements 26 are extended from the Vorstapelschacht 20, to then complete the lying on the additional sheet 14 parts stack 34 on the slide plates 24. Meanwhile, the shaft 36 is rotated about the axis of rotation 38 by 180 ° and the shaft bottom 40 raised so far that the uppermost product of the resting thereon partial stack 34 is located a short distance below the slide plates 24, to then pull out the slide plates 24 from the Pre-stacking shaft 20 to the next sub-stack take. Here, too, the lowermost sub-stack 34 of the future ready-made stack 54 has an additional sheet 14 - the cover sheet - on; the partial stacks 34 are separated from one another by means of a dividing sheet and have the corresponding number of printed products 28.

Es ist auch möglich, falls einem Empfänger eine grosse Anzahl Druckereiprodukte 28 zugeordnet ist, zwischen einem Deckblatt und einem Trennblatt oder auf einem Trennblatt zwei oder mehr Teilstapel 34 anzuordnen, welche nicht durch ein weiteres Zusatzblatt 14 getrennt, jedoch zueinander um 180° versetzt aufeinander abgelegt sind.It is also possible, if a receiver is associated with a large number of printed products 28, to arrange two or more partial stacks 34 between a cover sheet and a separating sheet which are not separated by another additional sheet 14 but offset from one another by 180 ° are.

Da die Vorrichtung 12 zum Zuführen und gegebenenfalls Bereitstellen und Bedrucken der Zusatzblätter 14 der Vorstapeleinrichtung 18 zugeordnet ist, wird eine grosse Verarbeitungskapazität erzielt. Dies umsomehr, wenn die Vorstapeleinrichtung 18 mit Zwischenbodenelementen 26 versehen ist.Since the device 12 for supplying and optionally providing and printing the additional sheets 14 is associated with the pre-stacking device 18, a large processing capacity is achieved. This even more so when the pre-stacking device 18 is provided with intermediate floor elements 26.

Eine Vorrichtung zum Zuführen, Bereitstellen und Bedrucken von Deckblättern kann beispielsweise derart ausgebildet sein, dass eine von einer Vorratsrolle abgezogene Papierbahn bedruckt und von dieser mittels einer Schneideinrichtung während des Zuführens in den Vorstapelschacht jeweils ein Abschnitt abgetrennt wird. Es ist selbstverständlich auch denkbar, dass von einem Magazin Zusatzblätter abgezogen, diese gegebenenfalls bedruckt und dann in den Vorstapelschacht 20 eingeführt werden. Um eine grosse Verarbeitungskapazität zu ermöglichen ist vorzugsweise jeder Stapelvorrichtung 10 eine eigene Vorrichtung 12 zum Zuführen und gegebenenfalls Bereitstellen und Bedrucken der Zusatzblätter 14 zugeordnet.A device for feeding, providing and printing of cover sheets may, for example, be designed in such a way that a paper web drawn off from a supply roll is printed and a portion is separated from it by means of a cutting device during feeding into the pre-stacking shaft. It is of course also conceivable that subtracted from a magazine additional sheets, these optionally printed and then introduced into the Vorstapelschacht 20. In order to enable a large processing capacity, each stacking device 10 is preferably assigned its own device 12 for supplying and possibly providing and printing the additional sheets 14.

Beim Zuförderer 30 kann es sich auch um einen Klammertransporteur handeln, bei welchem jedes Druckereiprodukt 28 von einer Klammer gehalten, dem Vorstapelschacht 20 zugeführt wird, wie dies beispielsweise aus der CH-A-667 065 und der entsprechenden US-A-4,565,130, der DE-A-27 52 513 oder DE-A-31 30 945 bekannt ist.The feed conveyor 30 may also be a staple conveyor in which each printed product 28 is held by a staple fed to the pre-stacking tray 20, as disclosed, for example, in CH-A-667 065 and corresponding US-A-4,565,130, DE -A-27 52 513 or DE-A-31 30 945 is known.

Der Vollständigkeit halber sei erwähnt, dass der Auslass 32 der Vorrichtung 12 zum Zuführen der Zusatzblätter 14 auch in einem grösseren Abstand oberhalb der Schieberplatten 24 in den Vorstapelschacht 20 einmünden kann, so dass die Deckblätter 14 jeweils auf-den Teilstapel, 34 zu liegen kommen. Bevorzugt befindet sich der Auslass 32, wie in Fig. 1 gezeigt, bei den Schieberplatten 24.For the sake of completeness, it should be mentioned that the outlet 32 of the device 12 for feeding the additional sheets 14 can also open at a greater distance above the slide plates 24 in the pre-stacking shaft 20, so that the cover sheets 14 each come to rest on the partial stack 34. Preferably, as shown in FIG. 1, the outlet 32 is located at the slide plates 24.

Der Schacht 36 kann auch ausgebildet sein, wie dies aus dem Stand der Technik bekannt ist. Der Schacht 36 braucht nicht zwingend um seine Achse drehbar zu sein.The well 36 may also be formed as known in the art. The shaft 36 does not necessarily have to be rotatable about its axis.

Es ist auch ein Ausstossen von Fertigstapeln 54 entgegen der Ausstossrichtung A möglich; dazu ist auf der der Umreifungsstation 16 abgewandten Seite der Stapelvorrichtung 10 ein Wegförderer angeordnet.It is also an ejection of ready stacks 54 against the ejection direction A possible; For this purpose, a removal conveyor is arranged on the side of the stacking device 10 facing away from the strapping station 16.

Ein drehbarer Schacht 36 wird je nach Bedürfnis vor der Aufnahme eines weiteren Teilstapels 34 gedreht oder nicht gedreht. Somit können Zusatzblätter 14 zwischen gleich ausgerichteten Teilstapeln 34 angeordnet werden.A rotatable shaft 36 is rotated according to need before receiving a further sub-stack 34 or not rotated. Thus, additional sheets 14 can be arranged between identically aligned sub-stacks 34.

Sämtliche Funktionen der Einrichtung werden mittels einer nicht gezeigten Steuerung gesteuert.All functions of the device are controlled by a controller, not shown.
