Definitions
- the present invention relates to a method for producing a printed product according to the preamble of claim 1.
- the invention also relates to transfer devices for carrying out such a method.
- EP 1 559 573 A1 For example, a method for producing printed matter such as books, brochures, magazines or the like has become known.
- printed sheets are each folded in a folding device in a printing press, conveyed to a stacking device and stacked in this to a book block.
- At least one additional sheet is added to a single sheet and the product of sheet and the added sheet added is stacked and stacked as a unit.
- the additional sheet is attached to a single sheet, the product of the single sheet and the supplement sheet is then stacked like the usual other sheets to the book block.
- Supplementary sheets of the type mentioned can consist for example of illustrations, color images or sheets printed on special paper.
- This book block with the inserted additional sheet can then be edited as usual, for example, bound by adhesive, cut, etc. It can also be inserted easily additional sheets. From this document also shows that the additional sheet with an investor withdrawn from a pile and then the single sheet can be added. It is also possible that the additional sheet is guided to a second conveyor and combined with this with a single signature, which is conveyed sequentially with a conveyor.
- the second conveying device is in this case preferably charged with a feeder. If several different supplementary sheets are to be provided, it is provided here to use a plurality of feeders, each of which dispenses an additional sheet to this second conveying device. Thus, it is possible here to form a book block with several different supplementary sheets, which additional sheets can be integrated at different locations of the book block. However, it is here that the supplemental sheet is attached to a single sheet.
- the invention aims to remedy this situation.
- the invention as characterized in the claims, the task is based on a method and a device of the type mentioned a printed sheet product flow split so controlled that it allows intervening clock gaps with Einsteckbogen resp. Additional sheet to provide.
- the object of the invention is also to enable a consistent stacking of said sheet to a book block in the wake.
- this object is achieved by proposing a method for producing a printed product, which comprises at least one Printed sheet and at least one additional sheet is composed. These sheets and supplementary sheets are printed sequentially. The printed sheets and / or the additional sheets are continuously assembled individually according to specific sequences within a transfer device and then selectively stacked.
- the transfer device has spaced-apart spaces or receiving points, which are in tact-related operative connection to the transport speed of the individually supplied printed sheet and additional sheet, and thus ensure an endless promotion.
- the individual brought-up printed sheet and additional sheet are cyclically targeted introduced into the individual spaces or receiving points within the transfer device.
- the actual transport takes place along a certain arc angle or along a certain distance, depending on the embodiment of the transfer device. It is readily possible in such a conveyor that the individual additional sheets are not placed monotonously in the clock gaps of the transfer device, but they can be readily attached or attached to an already placed sheet, which maximizes the flexibility of the inventive method.
- the essential advantage of the invention lies in the fact that the feeding and insertion of illustrations or the like into a printed product, for example in a book, is flexible and easy to carry out.
- the supplying stream of printed sheets which essentially form the actual content of the printed product, is first transferred to a transfer device, wherein the cadence of the brought-up sheet and additional sheet is in a certain operative connection with the conveying speed of the transfer device in their operation. From this it can be provided that the cadence of the brought-up printed sheet or the conveying speed of the transfer device can be selected individually so that clocks can be omitted as a placeholder for the subsequently added additional sheet.
- Such an operative connection between the individual operational Speeds can preferably be achieved with a comprehensive adaptive control.
- Another essential advantage of the invention is to be seen in the fact that the conveyor system in the environment of the transfer device can be extended by means of a circulating chain with grippers (see to supplement this technical environment EP 1 312 568 ). Seen in this way, every second gripper can be fed with a printing sheet, whereby the position-relevant gripper can be fed by another product stream before or after an additional sheet, such that in a following step the said sheets are all taken out of the transfer device and stacked into book blocks can.
- the method thus constructed allows very high speeds in the insertion process, which at the same time allow high speeds to print on-line the feeding streams in terms of both the signatures and the supplementary sheets.
- Another advantage of the invention lies in the fact that the sheet, and if necessary, the additional sheet, can be produced with their content from a digital printing press, these sheets can also be printed sequentially. If a printed product is printed sequentially, this means that the digital printing press begins with the first printed sheet of the printed product, and the subsequent printed sheets, which complete the printed product, are added immediately. Digital printing machines work without a fixed printing plate, and therefore can operate in the mentioned way.
- the transfer device forms a central element of the process.
- this transfer device from a blade-like infeed star, also called fan wheel formed, which receives the zoomed sheet and / or additional sheet between the spaces created for this, whereby by the rotational movement of this fan wheel these sheets are then within a certain arc angle and along at least one level forwarded and then stacked to a book block.
- the elements of the inlet star may be straight or have a blade-like curved geometry.
- Such a transfer device is formed on the basis of an endless transport chain, said chain has spaced apart pocket-shaped receiving points, wherein the print and additional sheets for further transport recording.
- the stacking of the sheet takes place.
- the spaces resp. the pocket-shaped receiving points can be extended if necessary with individual holding means which fixes the individual sheets at least during transport position stable non-positively.
- a further advantage of the invention relates to the variability in how the printing and additional sheets can be transported along the respective feeding transport path: they can be individually spaced apart or conveyed further by means of a shingled stream, and furthermore they can be conveyed upstream of the transfer device by means of a simple or Always upstream of this transfer device, these folds can preferably be carried out after a preceding separation operation, wherein such separation operations can be made longitudinally or transversely to the printed paper web, which leads to a high flexibility of the method.
- Fig. 1 Subsequently, the transport 11 of the folded printed sheet 10, and then the transfer of the same to a transfer device 3, which consists of a fan wheel with paddle-like pockets.
- 21 additional sheets 20 are introduced via a separately operated product stream, which are introduced into the spaces 13 of the transfer device 3 predefined by a controller 43.
- the transfer device 3 conveys fan-shaped the zoomed and placed in the spaces 13 printing and additional sheet on a certain arc angle on, so that these sheets and additional sheets leak at a certain point from the spaces 13 or are ejected and then stacked directly to a stack 30 become. This stacking therefore forms a congruent sequence of the continuous within the transfer device 3 compiled print and supplemental sheet.
- Fig. 1 how out Fig. 1 it can be seen, individual tailored signatures 1 are folded in the transverse direction by a folding device 2 to form a sheet 10.
- the supplied printed sheet 44 may already have one or more fold breaks.
- the sheet 10 and additional sheet 20 can be printed as a single sheets.
- the representation according to Fig. 1 here, however, refers to a folding device, which is designed so that the back fold 12 of the sheet 10 is in advance in the transport direction 11 so that it can be easily inserted and positioned in the associated space 13.
- this does not mean that the advance back fold represents a compelling transport process.
- a sheet 10 or additional sheet 20 can also be fed with an open side ahead.
- the printed sheets 10 are released after an angular movement of about 180 ° from the spaces 13 respectively. ejected, wherein the respective back fold 12 is trailing, that has the same book block-related position as upstream of the transfer device, and the folded sheet 10 now, based on the stack 30, front one or more openings.
- the same also applies to the numericalfalzes 12 for the additional sheet 20, if such a fold is made.
- These additional sheets take intermediate the free bars between the unoccupied by the sheet 10 spaces 13 in the fan wheel, the latter being transported over an arc angle, ie via a rotary or quasi-rotary translation of exemplary about 90 °.
- the additional sheets 20 can not exclusively occupy individual free spaces 13, but they can, depending on the composition of the book block, readily be inserted directly into the open fold of each sheet 10, in which case opening systems must be provided. This is particularly useful if the additional sheet in the book block has to fulfill the function of a Einsteckbogens.
- the fan-shaped subdivision of this transfer device 3 has individual scoop-shaped elements 4 concavely curved in the direction of rotation, the course of which acts in particular against the centrifugal forces arising in the direction of rotation.
- the concave curvature of the blade-shaped elements 4 on the inside therefore increases the centripetal force emanating from the mass of the transported sheets, so that the sheets remain stable during transport even at high rotations.
- the curvature of the paddle-shaped elements reverses their affinity in the region of the stacking and causes the sheets to more easily slip out of the gap 13 in the region of the stacking over the convex surface of the paddle-shaped element, such curvature also providing a transfer of the sheets in conformity with the movement ensures the stacking, in particular when the transfer dynamics is unwound so that the front of the sheet to be deposited is previously ejected and successively deposited by the rotation, so that a pressure-related stabilizing effect of the incoming sheet over the preceding sheet is formed, this is particularly true if the stacking process intermittently resp. flying done.
- the elements 4 of the fan wheel need not necessarily be formed scoop-shaped, namely they serve primarily to separate the individual sheets 10 and additional sheet 20 from each other and the pocket-shaped gap to accommodate additional sheets 20 to be determined by the controller 43 continuously, also adaptively , This control thus determines how the spaces 13 are clocked, i. Interspaces can be provided after a monotonous cycle, ie after every printing sheet, or after every two successive printed sheets, etc., or else sequences can be provided whose interspaces are arranged according to irregular arithmetic or geometric series of numbers.
- Fig. 2 shows a further transfer device 40, which is designed as a transport chain.
- This endlessly running transport chain 40 which here in the Fig. 2 simplicity is shown, is equipped with spaced and upper side open channels 41, which fulfill the function of receiving points equipped, which behave towards the sheet like pockets, and which are designed for the continuous recording and transport of sheet 10 and additional sheet 20.
- the channels 41 may also be designed as brackets, which exert a force-locking holding force on the printed product.
- the opening width of the open slot 42 is dimensioned so that said sheets 10, 20 can be easily inserted during delivery, that these sheets can be transported position stable during translation, and then these sheets can easily eject in the stacking.
- this receiving location is of the utmost importance, since the impacted cycles are extremely high, so that centrifugal forces and fluttering movements and other interferences can automatically arise, which indicate the rigidity of the folded ones indicated by the stiffness could easily exceed the printed sheet.
- This narrow design of the receiving location is an essential component of the transfer device, also because it is not excluded that the additional sheet may consist of individual non-folded sheet.
- Fig. 2 acts a controller, not shown, which is similar to in Fig. 1 is constructed.
- interspaces may be provided after a monotonous clock, ie after each print sheet, or after two consecutive press sheets, etc., or sequences may also be provided become, whose interspaces are arranged according to irregular arithmetic or geometric series of numbers.
- the transfer devices 3, 40 described are constructed so that the forces which occur in the case of high-performance transportation of the printed sheets and additional sheets and the subsequent stacking, such as the centrifugal forces in the star-shaped transfer device 3, can not have any negative effects on the formation of the stack , Folded sheets generally have a very high dimensional stability, which is advantageous for the reliable and dimensionally accurate stacking.

Description
Die vorliegende Erfindung betrifft ein Verfahren zum Herstellung eines Druckerzeugnisses gemäss Oberbegriff des Anspruchs 1. Die Erfindung betrifft auch Übergabevorrichtungen zur Durchführung eines solchen Verfahrens.The present invention relates to a method for producing a printed product according to the preamble of
Aus
Sind aber demgegenüber Buchblocks zu bilden, bei welchen die Zusatzbogen unregelmässig und nicht sequenzmonoton beigelegt werden müssen, oder mehrere Zusatzbogen unmittelbar nacheinander folgen sollen, oder die Zusatzbogen mindestens teilweise als Druckbogen ausgebildet sind, so stossen die zum Stand der Technik bekannt gewordenen Einrichtungen hinsichtlich Positionsgenauigkeit und Taktleistung an ihre betriebsimmanente Grenzen. Punktuelle Verbesserungen sind hier zwar möglich, sie sind aber stets mit einem relativ grossen Aufwand verbunden.If, on the other hand, book blocks are to be formed in which the additional sheets must be irregularly and not sequentially monotonously, or if additional sheets are to follow one after the other, or if the supplementary sheets are at least partially formed as printed sheets, then the devices known from the prior art meet with regard to position accuracy and Clock power to their internal operating limits. Although occasional improvements are possible here, they are always associated with a relatively large effort.
Hier will die Erfindung Abhilfe schaffen. Der Erfindung, wie sie in den Ansprüchen gekennzeichnet ist, liegt die Aufgabe zugrunde, bei einem Verfahren und einer Vorrichtung der eingangs genannten Art eine Druckbogen-Produktströmung so kontrolliert aufzuteilen, dass sie erlaubt, dazwischen befindlichen Taktlücken mit Einsteckbogen resp. Zusatzbogen zu versehen. Aufgabe der Erfindung ist es auch, im Nachgang eine konsistente Stapelung der genannten Bogen zu einem Buchblock zu ermöglichen.The invention aims to remedy this situation. The invention, as characterized in the claims, the task is based on a method and a device of the type mentioned a printed sheet product flow split so controlled that it allows intervening clock gaps with Einsteckbogen resp. Additional sheet to provide. The object of the invention is also to enable a consistent stacking of said sheet to a book block in the wake.
Erfindungsgemäss wird diese Aufgabe gelöst, indem ein Verfahren zur Herstellung eines Druckerzeugnisses vorgeschlagen wird, welches aus mindestens einem Druckbogen und mindestens einem Zusatzbogen zusammengesetzt ist. Diese Druckbogen und Zusatzbogen werden sequentiell gedruckt.
Die Druckbogen und/oder die Zusatzbogen werden innerhalb einer Übergabevorrichtung fortlaufend individuell nach bestimmten Sequenzen zusammengestellt und anschliessend gezielt gestapelt.According to the invention, this object is achieved by proposing a method for producing a printed product, which comprises at least one Printed sheet and at least one additional sheet is composed. These sheets and supplementary sheets are printed sequentially.
The printed sheets and / or the additional sheets are continuously assembled individually according to specific sequences within a transfer device and then selectively stacked.
Die Übergabevorrichtung weist zueinander beabstandete Zwischenräume oder Aufnahmestellen auf, welche in taktbezogener Wirkverbindung zur Transportgeschwindigkeit der einzeln zugeführten Druckbogen und Zusatzbogen stehen, und so eine endlose Förderung sicher stellen. Die einzelnen herangeführten Druckbogen und Zusatzbogen werden taktweise gezielt in die einzelnen Zwischenräume oder Aufnahmestellen innerhalb der Übergabevorrichtung eingebracht.The transfer device has spaced-apart spaces or receiving points, which are in tact-related operative connection to the transport speed of the individually supplied printed sheet and additional sheet, and thus ensure an endless promotion. The individual brought-up printed sheet and additional sheet are cyclically targeted introduced into the individual spaces or receiving points within the transfer device.
Der eigentliche Transport geschieht entlang eines bestimmten Bogenwinkels oder entlang einer bestimmten Strecke, je nach Ausführungsart der Übergabevorrichtung. Es ist bei einer solchen Fördereinrichtung ohne Weiteres möglich, dass die einzelnen Zusatzbogen nicht monoton in den Taktlücken der Übergabevorrichtung platziert werden, sondern sie können ohne Weiteres einem bereits platzierten Druckbogen beigelegt oder beigefügt werden, was die Flexibilität des erfindungsgemässen Verfahrens maximiert.The actual transport takes place along a certain arc angle or along a certain distance, depending on the embodiment of the transfer device. It is readily possible in such a conveyor that the individual additional sheets are not placed monotonously in the clock gaps of the transfer device, but they can be readily attached or attached to an already placed sheet, which maximizes the flexibility of the inventive method.
Der wesentliche Vorteil der Erfindung ist darin zu sehen, dass das Zuführen und Einstecken von Illustrationen oder dergleichen in ein Druckprodukt, beispielsweise in ein Buch, flexibel und leicht durchführbar ist. Dabei wird der zuführende Strom an Druckbogen, welche im Wesentlichen den eigentlichen Inhalt des Druckproduktes bilden, zunächst an eine Übergabevorrichtung übergeben, wobei bei deren Betrieb die Kadenz der herangeführten Druckbogen und Zusatzbogen in einer bestimmten Wirkverbindung mit der Fördergeschwindigkeit der Übergabevorrichtung steht. Daraus lässt sich vorsehen, dass die Kadenz der herangeführten Druckbogen oder die Fördergeschwindigkeit der Übergabevorrichtung individuell so gewählt werden können, dass Takte als Platzhalter für die anschliessend hinzukommenden Zusatzbogen ausgelassen werden können. Eine solche Wirkverbindung zwischen den einzelnen betrieblichen Geschwindigkeiten lässt sich vorzugsweise mit einer übergreifenden adaptive Steuerung/Regelung erzielen.The essential advantage of the invention lies in the fact that the feeding and insertion of illustrations or the like into a printed product, for example in a book, is flexible and easy to carry out. In this case, the supplying stream of printed sheets, which essentially form the actual content of the printed product, is first transferred to a transfer device, wherein the cadence of the brought-up sheet and additional sheet is in a certain operative connection with the conveying speed of the transfer device in their operation. From this it can be provided that the cadence of the brought-up printed sheet or the conveying speed of the transfer device can be selected individually so that clocks can be omitted as a placeholder for the subsequently added additional sheet. Such an operative connection between the individual operational Speeds can preferably be achieved with a comprehensive adaptive control.
Ein weiterer wesentlicher Vorteil der Erfindung ist hier darin zu sehen, dass das Fördersystem im Umfeld der Übergabevorrichtung mittels einer umlaufenden Kette mit Greifern erweitert werden kann (Siehe zur Ergänzung dieses technischen Umfeldes
Daraus ergeben sich hier die vorteilhaften Aspekte, dass das so aufgebaute Verfahren sehr hohe Geschwindigkeiten beim Einsteckvorgang erlaubt, wobei diese hohen Geschwindigkeiten gleichzeitig erlauben, die zuführenden Ströme sowohl hinsichtlich der Druckbogen als auch der Zusatzbogen online zu drucken.Another essential advantage of the invention is to be seen in the fact that the conveyor system in the environment of the transfer device can be extended by means of a circulating chain with grippers (see to supplement this
This results in the advantageous aspects that the method thus constructed allows very high speeds in the insertion process, which at the same time allow high speeds to print on-line the feeding streams in terms of both the signatures and the supplementary sheets.
Ein weiterer Vorteil der Erfindung ist darin zu sehen, dass die Druckbogen, und bei Bedarf auch die Zusatzbogen, mit ihrem Inhalt ab einer Digitaldruckmaschine hergestellt werden können, wobei diese Bogen auch sequentiell gedruckt werden können. Wird ein Druckprodukt sequentiell gedruckt, heisst das, dass die Digitaldruckmaschine mit dem ersten Druckbogen des Druckprodukts beginnt, und die darauffolgenden Druckbogen, welche das Druckprodukt komplettieren, gleich angefügt werden. Digitaldruckmaschinen arbeiten ohne eine feste Druckform, und können deshalb in der genannten Art operieren.Another advantage of the invention lies in the fact that the sheet, and if necessary, the additional sheet, can be produced with their content from a digital printing press, these sheets can also be printed sequentially. If a printed product is printed sequentially, this means that the digital printing press begins with the first printed sheet of the printed product, and the subsequent printed sheets, which complete the printed product, are added immediately. Digital printing machines work without a fixed printing plate, and therefore can operate in the mentioned way.
Dabei bildet die Übergabevorrichtung ein zentrales Element des Verfahrens.In this case, the transfer device forms a central element of the process.
Vorteilhaft wird diese Übergabevorrichtung aus einem schaufelähnlichen Einlaufstern, auch Fächerrad genannt, gebildet, welcher die herangeführten Druckbogen und/oder Zusatzbogen zwischen den dafür geschaffenen Zwischenräumen aufnimmt, wobei durch die rotative Bewegung dieses Fächerrades werden diese Bogen dann innerhalb eines bestimmten Bogenwinkels und entlang mindestens einer Ebene weiterbefördert und anschliessend zu einem Buchblock gestapelt. Die Elemente des Einlaufsterns können gerade ausgebildet sein, oder eine schaufelähnlich gekrümmte Geometrie aufweisen.Advantageously, this transfer device from a blade-like infeed star, also called fan wheel formed, which receives the zoomed sheet and / or additional sheet between the spaces created for this, whereby by the rotational movement of this fan wheel these sheets are then within a certain arc angle and along at least one level forwarded and then stacked to a book block. The elements of the inlet star may be straight or have a blade-like curved geometry.
Eine weitere vorzugsweise gewählte Ausführung einer solchen Übergabevorrichtung wird anhand einer endlosen Transportkette gebildet, wobei diese Kette zueinander beabstandete taschenförmige Aufnahmestellen aufweist, worin die Druck- und Zusatzbogen für den Weitertransport Aufnahme finden. Vorzugsweise bei einer ersten Richtungsänderung der Transportkette findet dann die Stapelung der Bogen statt. Die Zwischenräume resp. die taschenförmigen Aufnahmestellen lassen sich bei Bedarf mit einzelnen Haltemitteln erweitern, welche die einzelnen Bogen mindestens während des Transportes positionsstabil kraftschlüssig fixiert.Another preferred embodiment of such a transfer device is formed on the basis of an endless transport chain, said chain has spaced apart pocket-shaped receiving points, wherein the print and additional sheets for further transport recording. Preferably, at a first change of direction of the transport chain then the stacking of the sheet takes place. The spaces resp. the pocket-shaped receiving points can be extended if necessary with individual holding means which fixes the individual sheets at least during transport position stable non-positively.
Ein weiterer Vorteil der Erfindung betrifft die Variabilität wie die Druck- und Zusatzbogen entlang des jeweiligen zuführenden Transportpfades transportiert werden können: Sie können einzeln beabstandet oder anhand eines Schuppenstromes weiter befördert werden, und darüber hinaus können sie, jeweils stromauf der Übergabevorrichtung, durch eine einfache oder mehrfache Falzung charakterisiert werden.. Immer stromauf dieser Übergabevorrichtung können diese Falzungen vorzugsweise nach einer vorangegangenen Trennoperation durchgeführt werden, wobei solche Trennoperationen längs oder quer zu der bedruckten Papierbahn vorgenommen werden können, was zu einer grossen Flexibilität des Verfahrens führt.A further advantage of the invention relates to the variability in how the printing and additional sheets can be transported along the respective feeding transport path: they can be individually spaced apart or conveyed further by means of a shingled stream, and furthermore they can be conveyed upstream of the transfer device by means of a simple or Always upstream of this transfer device, these folds can preferably be carried out after a preceding separation operation, wherein such separation operations can be made longitudinally or transversely to the printed paper web, which leads to a high flexibility of the method.
Grundsätzlich geht man davon aus, dass die Druckbogen, und selbstverständlich bei Bedarf auch die Zusatzbogen, anhand einer einfachen Falzung bearbeitet werden. Es ist indessen ohne Weiteres möglich, auch mehrfache, für den Druckbogen steifigkeitsfördernde Falzungen vorzusehen, wobei dann nach der Stapelung zu Druckprodukten und im Nachgang zu allfälligen Weiterverarbeitungen mittels dem Formatbeschnitt die überschüssigen Falzränder abgeschnitten werden.Basically, it is assumed that the printed sheets, and of course, if necessary, the additional sheet, are processed by a simple fold. However, it is readily possible to provide multiple, for the sheet stiffness-promoting folds, in which case after the stacking to print products and subsequent to any further processing by means of the size trim the excess seaming margins are cut off.
Vorteilhafte und zweckmässige Weiterbildungen der erfindungsgemässen Aufgabenlösung sind in den weiteren abhängigen Ansprüchen gekennzeichnet.Advantageous and expedient developments of the inventive task solution are characterized in the further dependent claims.
Im Folgenden wird anhand der Zeichnung Ausführungsbeispiele der Erfindung näher erläutert. Alle für das unmittelbare Verständnis der Erfindung unwesentlichen Merkmale sind fortgelassen worden. Gleiche Merkmale sind in den verschiedenen Figuren mit den gleichen Bezugszeichen versehen.In the following, embodiments of the invention will be explained in more detail with reference to the drawing. All features that are immaterial to the instant understanding of the invention have been omitted. Identical features are provided in the various figures with the same reference numerals.

Wie aus
Bereits durch eine einfache Falzung lässt sich für den Transport der Druck- und Zusatzbogen eine gute stabilisierende Steifigkeit erzielen, so dass auch die anschliessende Stapelung 30 positionssicher erfolgen kann. Hierzu wird auf die unterstehenden Ausführungen verwiesen. Die Zusatzbogen 20 können indessen nicht ausschliesslich einzelne freie Zwischenräume 13 belegen, sondern sie können, je nach Zusammensetzung des Buchblocks, ohne Weiteres direkt in die offene Falzung eines jeden Druckbogens 10 eingeschoben werden, wobei dann Öffnungssysteme vorgesehen werden müssen. Dies ist insbesondere dann sinnvoll, wenn der Zusatzbogen im Buchblock die Funktion eines Einsteckbogens zu erfüllen hat.Already by a simple folding can be achieved for the transport of printing and additional sheet a good stabilizing stiffness, so that the subsequent stacking 30 can be made positionally secure. Reference is made to the explanations below. However, the
Damit wird die Flexibilität des Systems offensichtlich, denn es lässt sich ohne Weiteres mit der gleichen Übergabevorrichtung 3 zusätzliche resp. verschiedene Produktströme mit unterschiedlichen Einsteckbogen vorsehen. Wie weiter unten noch näher eingegangen wird, weist die fächerradförmige Unterteilung dieser Übergabevorrichtung 3 einzelne in Drehrichtung konkav gekrümmte schaufelförmige Elemente 4 auf, deren Verlauf insbesondere gegen die in Rotationsrichtung entstehenden Zentrifugalkräfte wirkt. Die innenseitig konkave Krümmung der schaufelförmigen Elemente 4 erhöht sonach die von der Masse der transportierten Bogen ausgehende Zentripetalkraft, so dass die Bogen während des Transportes auch bei hohen Rotationen lagestabil bleiben. Die Krümmung der schaufelförmigen Elemente kehrt im Bereich der Stapelung ihre Affinität um, und bewirkt, dass die Bogen im Bereich der Stapelung über die konvexe Oberfläche des schaufelförmigen Elementes leichter aus dem Zwischenraum 13 rutschen können, wobei eine solche Krümmung auch eine bewegungskonforme Übergabe der Bogen an die Stapelung sicherstellt, insbesondere wenn die Übergabedynamik so abgewickelt wird, dass die Vorderseite des abzulegenden Bogens vorangehend ausgestossen und sukzessiv durch die Rotation abgelegt wird, so dass eine druckbezogene stabilisierende Wirkung des ankommenden Bogens gegenüber dem vorangehenden Bogen entsteht, wobei dies insbesondere dann zum Tragen kommt, wenn der Stapelungsvorgang intermittierend resp. fliegend erfolgt. Die Elemente 4 des Fächerrades müssen nicht zwingend schaufelförmig ausgebildet sein, sie dienen nämlich primär die einzelnen Druckbogen 10 und Zusatzbogen 20 voneinander zu trennen sowie die taschenförmige Lücke zur Aufnahme weiterer Zusatzbogen 20 zu bilden, die von der Steuerung 43 fortlaufend, auch adaptiv, bestimmt wird. Diese Steuerung bestimmt also, wie die Zwischenräume 13 getaktet werden, d.h. es können Zwischenräume nach einem monotonen Takt vorgesehen werden, also nach jedem Druckbogen, oder nach jeweils zwei aufeinanderfolgenden Druckbogen, etc., oder es können auch Abfolgen vorgesehen werden, deren Zwischenräume nach unregelmässigen arithmetischen oder nach geometrischen Zahlenreihen disponiert sind.Thus, the flexibility of the system is obvious, because it can be easily with the
Die Flexibilität des Systems ist erst dann maximiert, wenn die Aufnahmestellen beliebige Druckbogen und beliebige Zusatzbogen fortlaufend aufnehmen und sicher transportiert werden können. Andererseits ist es richtig, dass insbesondere die Druckbogen 20 nicht allzu sehr in den von den Schlitzen 42 indizierten Halteklammern klemmen dürfen, denn dies könnte deren Ausstossung im Bereich der Stapelung 30 wesentlich hemmen, was zu einer Störung des Prozesses und zu einer fehlerhaften Stapelbildung führen könnte. Auch beim System gemäss
Es gilt auch hier, dass diese Steuerung bestimmt, wie die Zwischenräume getaktet werden sollen, d.h. es können Zwischenräume nach einem monotonen Takt vorgesehen werden, also jeweils nach jedem Druckbogen, oder jeweils nach zwei aufeinanderfolgenden Druckbogen, etc., oder es können auch Abfolgen vorgesehen werden, deren Zwischenräume nach unregelmässigen arithmetischen oder nach geometrischen Zahlenreihen disponiert sind.It also applies here that this control determines how the interspaces are to be clocked, ie, interspaces may be provided after a monotonous clock, ie after each print sheet, or after two consecutive press sheets, etc., or sequences may also be provided become, whose interspaces are arranged according to irregular arithmetic or geometric series of numbers.
Grundsätzlich sind die beschriebenen Übergabevorrichtungen 3, 40 so aufgebaut, dass die bei einem auf Hochleistung ausgelegten Transport der Druckbogen und Zusatzbogen und der anschliessenden Stapelung auftretenden Kräfte, wie beispielsweise die Zentrifugalkräfte bei der sternförmigen Übergabevorrichtung 3, keine negativen Auswirkungen auf die Bildung der Stapelung haben können. Gefalzte Druckbogen weisen im Allgemeinen eine sehr hohe Formstabilität auf, welche sich vorteilhaft für das zuverlässige und formgenaue Stapeln auswirkt.In principle, the
