Description

Die vorliegende Erfindung betrifft ein Verfahren zum Beschriften gefalteter Druckereiprodukte, wie gefalteter Einzelbögen oder gefalteter Hefte, auf einer innenliegenden Seite, insbesondere, jedoch nicht ausschließlich, in einem Randbereich derselben, bei dem die jeweiligen gefalteten Druckereiprodukte von einer Fördereinrichtung gefördert, zumindest teilweise geöffnet und an einem Druckkopf, insbesondere an einen Tintenstrahlschreiber, vorbeigeführt werden, und bei dem die Beschriftung mindestens der einen Hälfte des jeweiligen Druckereiproduktes in einem zumindest im wesentlichen ebenen Bereich desselben erfolgt, sowie Vorrichtungen zur Durchführung dieses Verfahrens. The present invention relates to a method for labeling folded printed products, such as folded Single sheets or folded booklets, on an inside Side, in particular, but not exclusively, in one Edge area of the same, in which the respective folded Printed products funded by a conveyor, at least partially opened and on a printhead, in particular past an inkjet pen, and where the inscription of at least half of the respective print product in one at least essentially flat area of the same, as well as devices to carry out this procedure.

Ein Verfahren der eingangs genannten Art ist aus der internationalen Patentanmeldung mit der Veröffentlichungsnummer WO 93/07081 bekannt. Das dort beschriebene Verfahren dient der Anbringung einer Beschriftung bzw. einer Unterschrift auf den inneren Seiten von einer Fördereinrichtung getragenen Büchern. Bei dieser Fördereinrichtung werden die Bücher im gefalteten Zustand getragen, wobei der Falz parallel zur Förderrichtung liegt und die beiden Hälften der jeweiligen Druckereiprodukte links und rechts der Fördereinrichtung angeordnet sind und von dieser nach unten hängen. Ein Führungscord befindet sich unterhalb der Fördereinrichtung und dient dazu, die zwei Hälften der Druckereiprodukte in geringem Abstand voneinander zu halten. Im Anschluß an das eine Ende des Cordes befindet sich ein pflugartiges Teil, das dazu dient, die eine Hälfte des gefalteten Druckereiproduktes aus der vertikalen Lage heraus zunehmend in eine horizontale Lage zu drehen, wobei die Beschriftung im Randbereich der Seite der horizontal geführten Hälfte der Bücher durch einen im Bereich des Auslaufendes des Pfluges angebrachten Druckkopf erfolgt. A method of the type mentioned is from the international Patent application with publication number WO 93/07081 known. The method described there serves the Attaching a label or signature to the inside pages of books carried by a conveyor. The books are folded in this conveyor Condition worn, the fold parallel to the conveying direction lies and the two halves of each Printed products arranged to the left and right of the conveyor are and hang down from this. A leadership cord is located below the conveyor and serves in addition, the two halves of the printed products at a short distance to keep from each other. Following one end of the Cordes has a plow-like part that is used to half of the folded printed product from the vertical position increasingly into a horizontal position   rotate, with the label on the edge of the side of the horizontally guided half of the books by one in the field at the outlet end of the plow.

Bei diesem bekannten Verfahren bzw. bei dieser bekannten Vorrichtung wird das Ziel verfolgt, die Beschleunigung der von der vertikalen Lage in die waagerechte Lage bewegten Hälfte der Druckereiprodukte möglichst konstant zu halten, da man sich hierdurch eine höhere Arbeitsgeschwindigkeit verspricht. In this known method or in this known device the goal is pursued, the acceleration of the the vertical position into the horizontal position to keep the printed products as constant as possible, since one this promises a higher working speed.

Problematisch bei dieser Anordnung dürfte sein, daß trotz der konstanten Beschleunigung die Beförderung der Druckereiprodukte mit dem Falz parallel zur Fördereinrichtung dazu führt, daß die hierdurch verdrängte Luft zwischen die Seiten der Druckprodukte drängt und eine Flatterbewegung derselben bewirkt, und zwar insbesondere dann, wenn eine höhere Umlaufgeschwindigkeit der Fördereinrichtung erwünscht ist. The problem with this arrangement may be that despite the constant acceleration of the transportation of printed products with the fold parallel to the conveyor causes the air displaced by this between the pages of the printed products and a fluttering movement of the same causes, especially when a higher rotational speed the conveyor is desired.

Zum Stand der Technik gehört auch das integrierte Inkjet-System der Firma Ferag AG, Hinwil / Schweiz, das eine Beschriftung von Randbereichen einzelner Seiten eines Druckereiproduktes ermöglicht, jedoch noch nicht dazu ausgelegt ist, eine Öffnung von gefalteten Druckereiprodukten zu Beschriftungszwecken zu ermöglichen. The integrated inkjet system is also part of the state of the art from Ferag AG, Hinwil / Switzerland, which has a label of marginal areas of individual pages of a printed product enabled, but not yet designed to do so is to open folded printed products To enable labeling purposes.

Die Aufgabe der vorliegenden Erfindung liegt darin, ein Verfahren bzw. eine Vorrichtung zum Beschriften der Innenseite eines Druckereiproduktes vorzusehen, und zwar derart, daß diese Beschriftung bei hoher Fördergeschwindigkeit der Druckereiprodukte zuverlässig und mit relativ geringem Aufwand erfolgen kann, wobei die zu beschriftende Seite im Bereich des Druckkopfes einwandfrei geführt ist und ein Flattern der Seiten der Druckereiprodukte nicht zu befürchten ist. The object of the present invention is a method or a device for labeling the inside to provide a printed product, in such a way that this labeling at a high conveyor speed Printed products reliably and with relatively little effort can be done, with the side to be labeled in the area the print head is properly guided and a flutter   the pages of the printed products are not to be feared is.

Zur Lösung dieser Aufgabe wird verfahrensmäßig erfindungsgemäß vorgesehen, daß die jeweiligen gefalteten Druckereiprodukte mit ihrem Falz quer zur Fördereinrichtung transportiert werden, und daß eine Öffnungseinrichtung für das Öffnen der Produkte in der oder entgegengesetzt zur Beförderungsrichtung sorgt, noch während die Greifer der Fördereinrichtung die beiden Hälften der jeweiligen Druckereiprodukte im Falzbereich halten und dort gegeneinander drücken. To achieve this object, the method according to the invention provided that the respective folded printed products transported across the conveyor with its fold and that an opening device for opening of the products in or opposite to the direction of transport ensures even while the gripper of the conveyor the two halves of the respective print products in Hold the fold area and press against each other there.

Durch die Beförderung der Druckereiprodukte mit ihrem Falz etwa rechtwinklig zur Fördereinrichtung wird die Gefahr des Flatterns der Seiten der Produkte weitestgehend vermieden, und zwar auch bei den hohen Transportgeschwindigkeiten, die möglich sind mit an sich bekannten Fördereinrichtungen dieser Art. Das Flattern der Seiten der Druckereiprodukte wird aber auch weiterhin unterbunden durch die Greifer, welche die zwei Hälften der jeweiligen Druckereiprodukte im Falzbereich zusammenhalten. By transporting the printed products with their fold approximately at a right angle to the conveyor, the risk of Fluttering of the sides of the products largely avoided, even at the high transport speeds that are possible with known conveyors Art. The fluttering of the pages of the printed products will continue to be prevented by the grabs which the two Hold halves of the respective print products together in the fold area.

Besonders günstig ist es, wenn das Öffnen der gefalteten Druckereiprodukte derart durchgeführt wird, daß eine Bogen- bzw. Schleifenbildung in mindestens der zu beschriftenden Hälfte der jeweiligen gefalteten Druckereiprodukte erfolgt, während der Randbereich dieser Hälfte über eine zumindest im wesentlichen ebene Führung geführt wird. It is particularly favorable when opening the folded Printing products is carried out in such a way that a sheet or Loop formation in at least the one to be labeled Half of the respective folded printed products are made, while the edge area of this half over at least in essential level leadership is performed.

Durch die gekrümmte Gestalt der Hälften der Druckereiprodukte aufgrund der Bogen- bzw. Schleifenbildung sorgt die eigene Elastizität der Druckereiprodukte dafür, daß der Randbereich der Hälfte an die Führung gepreßt wird, wodurch jegliches Flattern ausgeschaltet werden kann und zudem eine genaue Positionierung des zu beschriftenden Bereiches in Bezug auf den Druckkopf erreichbar ist. Due to the curved shape of the halves of the printed products due to the formation of arcs or loops, your own Elasticity of the printed products that the edge area half pressed against the guide, causing any   Flutter can be turned off and also accurate positioning of the area to be labeled in relation to the Printhead is accessible.

Das Verfahren kann auch so ausgeführt werden, daß im Bereich des Druckkopfes nach der teilweisen Öffnung der Druckereiprodukte die zwei Hälften der jeweiligen Druckereiprodukte unterhalb der Greifer der Fördereinrichtung, jedoch oberhalb des zu beschriftenden Randbereiches aufeinander zu bewegt werden, um die Krümmung des Bogens bzw. der Schleife zu erhöhen. Hierdurch kann eine Erhöhung des Kontaktdruckes zwischen der Führung und dem Randbereich des Druckereiproduktes erzielt werden, so daß sich eine optimale Positionierung und Führung der Druckereiprodukte im Bereich des Druckkopfes ergibt. Besonders günstig ist, daß die Teile, welche die zwei Hälften der jeweiligen Druckereiprodukte aufeinander zu bewegen, trotz hoher Arbeitsgeschwindigkeit keine ausgeprägte Schlupfbewegung entlang der Außenseiten der gefalteten Druckereiprodukte auszuführen brauchen, so daß die Beschädigung des bereits erfolgten Druckbildes durch solche Teile nicht zu befürchten ist. The method can also be carried out so that in the area of the printhead after the partial opening of the print products the two halves of each print product below the gripper of the conveyor, but above of the edge area to be labeled moved towards each other to increase the curvature of the bow or loop. This can increase the contact pressure between the guide and the edge area of the printed product achieved be, so that an optimal positioning and Management of the print products in the area of the print head results. It is particularly favorable that the parts which the two To move halves of the respective printed products onto one another, not a distinct one despite the high working speed Slip movement along the outside of the folded Printing products need to run, so the damage of the print image already made by such parts is not to be feared.

Bei der Ausführungsform gemäß Fig. 1 ist mit dem Bezugszeichen 10 eine Fördereinrichtung zur Beförderung von gefalteten Druckereiprodukten 12 in Form einer aufgefächerten Schuppenformation gezeigt. Die Förderrichtung ist mit 14 angegeben, d.h. die einzelnen Greifer 16 der Fördereinrichtung, welche die jeweiligen gefalteten Druckereiprodukte 12 tragen, sind in gleichmäßigen Abständen voneinander angeordnet und werden in Förderrichtung 14 bewegt. In the embodiment according to FIG. 1, the reference number 10 a conveyor for the transport of folded Printed products 12 in the form of a fanned out Scale formation shown. The direction of conveyance is indicated at 14, i.e. the individual grippers 16 of the conveyor, which carry the respective folded printed products 12, are evenly spaced from each other and are moved in the conveying direction 14.

Die Greifer 16 halten je ein gefaltetes Druckereiprodukt 12 im Bereich unmittelbar unterhalb des jeweiligen Falzes 18. Solche Greifer sind in der Praxis bestens bekannt, und die Greiffinger 20 und 22 der einzelnen Greifer können zur Aufnahme oder Abgabe eines gefalteten Druckereiproduktes geöffnet und geschlossen werden. Die Greifer sind alle in Fig. 1 in geschlossenem Zustand gezeigt. The grippers 16 each hold a folded printed product 12 in the area immediately below the respective fold 18. Such grippers are well known in practice, and the Gripper fingers 20 and 22 of the individual grippers can be used for receiving or delivery of a folded printed product opened   and be closed. The grippers are all in Fig. 1st shown in the closed state.

Es kann sich bei den Druckereiprodukten 12 um einzelne gefaltete Blätter handeln, die anschließend mit anderen Blättern zu einem vollständigen Heft wie bspw. einer Zeitschrift oder einem Teil davon zusammengestellt werden. Es kann sich aber auch um einige zusammengefaltete Blätter handeln, die anschließend mit weiteren zusammengefalteten Blättern zu einem vollständigen Produkt, wie bspw. einer Zeitschrift oder einem Buch zusammengeführt werden, oder es kann sich um bereits fertiggestellte Zeitschriften, Hefte oder ähnliche Produkte handeln. In jedem Fall, und dies gilt auch für alle weiteren Ausführungsbeispiele, ist es erwünscht, in einem Randbereich der Innenseite des Druckereiproduktes eine Beschriftung mittels eines Druckkopfes 24 vorzunehmen, wobei die Beschriftung bspw. ganz individuell erfolgen kann. Beispielsweise kann der Name eines das Druckereiprodukt beziehenden Kunden im Randbereich der Innenseite gedruckt werden. Bei dem Randbereich kann es sich um einen seitlichen Randbereich des Druckereiproduktes handeln, d.h. um den Randbereich, der parallel zum Falz 18, jedoch entfernt davon liegt, oder es kann sich um den oberen oder unteren Rand der betreffenden Seite handeln. The printed products 12 can be individually folded Trade leaves that then trade with other leaves to a complete issue such as a magazine or part of it can be put together. But it can also act on some folded sheets that subsequently with further folded sheets into one complete product, such as a magazine or a Book can be merged, or it may already be finished magazines, booklets or similar products act. In any case, and this also applies to all others Embodiments, it is desirable in an edge area inscription on the inside of the printed product make a printhead 24, the label For example, can be done individually. For example, the Name of a customer who purchases the print product in the peripheral area be printed on the inside. At the edge area it can be a lateral edge area of the printed product act, i.e. around the edge area, which is parallel to the Fold 18, however, is distant from it, or it may be trade the top or bottom of that page.

Eine mögliche Anwendung der Vorrichtung betrifft Kataloge, in deren Innerem in der Mitte eine Bestellkarte eingeheftet ist, auf deren Innenseite bereits die Adresse des Bestellers, d.h. des Empfängers dieses Katalogs aufgedruckt ist. Wünscht bspw. der Besteller den angebotenen Artikel oder mehrere davon zu beziehen, so braucht er lediglich die Bestellkarte mit der Bestellinformation, nicht jedoch mit seiner Anschrift zu versehen. A possible application of the device relates to catalogs in whose inside is an order card in the middle, the address of the customer, i.e. of the recipient of this catalog is printed. For example, the customer to the offered article or several of them order, he only needs the order card with the Order information, but not to include its address.  

Bei der Herstellung der Bestellkarte muß die gefaltete Bestellkarte daher vor dem Sammeln geöffnet und mit der gewünschten Anschrift bedruckt werden. When manufacturing the order card, the folded order card must be therefore opened before collecting and with the desired one Address can be printed.

Da der Katalog aus mehreren gefalteten Teilen besteht, ist es möglich, für jede Innenseite eines gefalteten Teils eine solche Bestellkarte vorzusehen. Obwohl die Beschriftungsvorrichtung der Fig. 1 (wie auch die anderen nachfolgend beschriebenen Beschriftungsvorrichtungen) in erster Linie dafür gedacht sind, Beschriftungen auf der mittleren Innenseite des jeweiligen gefalteten Druckereiproduktes vorzunehmen, können bei Zusammenstellung von mehreren gefalteten Druckereiprodukten, welche jeweils Beschriftungen auf der mittleren Innenseite aufweisen, Beschriftungen erreicht werden, die nicht nur auf der mittleren Innenseite des fertigen Produktes vorliegen. Since the catalog consists of several folded parts, it is possible, one for each inside of a folded part Order card to be provided. Although the labeling device 1 (as well as the others described below Labeling devices) primarily for this are intended, inscriptions on the middle inside of the each folded printed product can make when putting together several folded printed products, which each have labels on the middle one Have inside, markings are achieved that not just on the middle inside of the finished product available.

Es geht bei der bevorzugten Vorrichtung darum, die gefalteten Druckereiprodukte, die im gefalteten Zustand gefördert werden, soweit zu öffnen, daß der zu beschriftende Randbereich frei zu liegen kommt. Dieser Randbereich muß für ein sauberes Schriftbild beim Beschriften zumindest im wesentlichen eben liegen. Das Öffnen der Druckereiprodukte bei der Ausführungsform gemäß der Fig. 1 erfolgt unter Anwendung einer Öffnungseinrichtung 26, welche so ausgebildet ist wie in der europäischen Patentanmeldung der gleichen Anmelderin mit der Veröffentlichungsnummer EP-A-0 564 812 offenbart ist, wobei die Öffnungseinrichtung dort einem anderen Zweck dient. The preferred device is about the folded ones Printed products that are conveyed when folded, Open so far that the edge area to be labeled comes to lie freely. This edge area must be clean Typeface when labeling at least essentially flat lie. Opening the print products in the embodiment 1 takes place using an opening device 26, which is designed as in the European Patent application by the same applicant with the Publication number EP-A-0 564 812, wherein the opening device serves another purpose there.

Diese Öffnungseinrichtung 26 nach der EP-A-0 564 812 besteht im wesentlichen aus zwei nebeneinander angeordneten umlaufenden Förderketten oder Riemen 28, 30, welche jeweilige Greifer 32 bzw. 34 tragen. Dabei ist die Anordnung so getroffen, daß die jeweils oberen Trume der beiden Fördereinrichtungen 28, 30 nebeneinanderliegen und sich ebenfalls in Pfeilrichtung 14 bewegen, wobei jedoch die Fördereinrichtung 30 etwas schneller läuft als die Fördereinrichtung 28 und diese sich mit im wesentlichen der Geschwindigkeit der Fördereinrichtung 10 bewegt. Dies führt dazu, daß die Greifer 34 sich zunehmend im Verlauf der Bewegung parallel zur Fördereinrichtung 10 von den Greifern 32 beabstanden. Dabei sind die Greifer 34, die jeweils eine Klemmzunge (nicht gezeigt) aufweisen, so ausgebildet, daß sie das vom Falz 18 abgewandte untere Ende 40 der vorderen Hälfte des gefalteten Druckereiproduktes festklemmen, wahrend der nachfolgend zum Einsatz kommende Greifer 32 für das gleiche gefaltete Druckereiprodukt 12 das vom Falz 18 abgewandte Ende 42 der hinteren Hälfte des gefalteten Druckereiproduktes aufnimmt. Zu diesem Zweck sind auch die Greifer 32 mit einer Klemmzunge 36 versehen. This opening device 26 according to EP-A-0 564 812 exists essentially of two circumferential ones arranged side by side Conveyor chains or belts 28, 30, each of which Wear gripper 32 or 34. The arrangement is made so   that the top dreams of the two conveyors 28, 30 next to each other and also in Move arrow direction 14, however, the conveyor 30 runs somewhat faster than the conveyor 28 and this is essentially at the speed of the conveyor 10 moves. As a result, the grippers 34 increasingly in the course of the movement parallel to the conveyor 10 spaced from the grippers 32. Are there the grippers 34, each of which has a clamping tongue (not shown) have, designed so that they facing away from the fold 18 lower end 40 of the front half of the folded printed product clamp while using the following coming gripper 32 for the same folded printed product 12 the end 42 of the rear facing away from the fold 18 Absorbs half of the folded printed product. To this The grippers 32 are also provided with a clamping tongue 36 for the purpose.

Bei dem Einlauf der gefalteten Druckereiprodukte im Bereich der Öffnungseinrichtung 26 sind diese bereits auf einer Führungsfläche 38 geführt, so daß sie die gekrümmte Form des auf der linken Seite dargestellten Druckereiproduktes 12 auf weisen und das vom Falz 18 abgewandten Ende 40 der vorderen Hälfte des gefalteten Druckereiproduktes 12 in Förderrichtung 14 betrachtet einen kleinen aber definierten Abstand 46 vom dem Falz 18 abgewandten Ende 42 der hinteren Hälfte des gefalteten Druckereiproduktes 12 aufweist. Der Greifer 34 kann somit zuverlässig in Berührung mit dem unteren Ende 40 der vorderen Hälfte des gefalteten Druckereiproduktes 12 gebracht werden, beispielsweise dann, wenn er um eine nicht gezeigte Umlenkwalze von unten kommend nach oben im Bereich des Abstandes 46 stößt, d.h. ähnlich wie in der Darstellung auf der linken Seite von Fig. 1 für den Greifer 32. When the folded printed products enter the area of the opening device 26, these are already on one Guide surface 38 guided so that it has the curved shape of the printed product 12 shown on the left have and the end 40 facing away from the fold 18 of the front Half of the folded printed product 12 in the conveying direction 14 considers a small but defined distance 46 from the fold 18 facing away from the end 42 of the rear half of the folded Printed product 12 has. The gripper 34 can thus reliably in contact with the lower end 40 of the brought front half of the folded printed product 12 be, for example, if it is a not shown Deflection roller coming from below upwards in the area of the distance 46 bumps, i.e. similar to the illustration on the 1 for the gripper 32.  

Für weitere Details der Ausbildung der Öffnungseinrichtung 26 wird auf die vorher erwähnte EP-A-0 564 812 verwiesen. For further details of the configuration of the opening device 26 reference is made to the aforementioned EP-A-0 564 812.

Der Druckkopf 24 ist im Bereich der ausgangsseitigen Umlenkwalze in der Öffnungseinrichtung 26 angeordnet und dazu ausgelegt, die hintere Hälfte des gefalteten, jedoch geöffneten Produktes im Randbereich zu beschriften. The print head 24 is in the region of the deflection roller on the output side arranged in the opening device 26 and designed to the back half of the folded but open one Label the product in the edge area.

Die genaue Ausbildung des Druckkopfes 24 ist für die vorliegende Erfindung im wesentlichen ohne Belang. Dieser Druckkopf ist aber vorzugsweise als Tintenstrahldrucker ausgebildet, wie in der europäischen Patentanmeldung der vorliegenden Anmelderin mit der Veröffentlichungsnummer EP-A-0 096 228 beschrieben. Für weitere Details wird auf diese frühere Anmeldung verwiesen. Auch hier gelten sämtliche für den Tintenstrahldrucker 18 gemäß der EP-A-0 096 228 geltend gemachten Vorteile, beispielsweise auch, daß das den Schreibvorgang auslösende Signal ferngesteuert entsprechend dem Takt der Fördereinrichtung erfolgen kann. Auch hier kann ein Wächter (nicht gezeigt) vorgesehen werden, um im Falle von nicht belegten Greifern den Beschriftungsvorgang zu unterbinden und eine Verschmutzung der Anlage mit Tinte zu verhindern. Diese Aussagen zu dem Druckkopf gelten auch für alle weiteren Ausführungsformen der Erfindung, die nachfolgend beschrieben werden. The exact design of the printhead 24 is for the present Invention essentially irrelevant. This printhead but is preferably designed as an inkjet printer, as in the European patent application of the present applicant with publication number EP-A-0 096 228. For further details please refer to this earlier registration referred. Here, too, everything applies to the inkjet printer 18 according to EP-A-0 096 228 Advantages, for example, that the writing process triggering signal remotely controlled according to the clock of the Conveyor can take place. Again, a guard can (not shown) to be provided in the case of unoccupied Grippers to prevent the labeling process and prevent contamination of the system with ink. This Statements on the printhead also apply to all other embodiments of the invention described below will.

Bei der Ausführung der Fig. 1 kann man sagen, daß die gefalteten Produkte nachlaufend sind, weil die gefalteten Produkte nach hinten gebogen sind. 1 can be said that the folded Products are trailing because of the folded products are bent backwards.

Die Ausführungsform gemäß Fig. 2 ist der Ausführungsform der Fig. 1 sehr ähnlich, und es werden, wie auch bei allen weiteren Ausführungsbeispielen, für gleiche Teile die gleichen Bezugszeichen verwendet, so daß eine detaillierte Beschreibung der einzelnen Teile im Zusammenhang mit den weiteren Ausführungsformen entbehrlich ist. 2 is the embodiment of Fig. 1 very similar, and it will, as with all others   Embodiments, the same for the same parts Reference numerals are used so that a detailed description of the individual parts in connection with the others Embodiments is unnecessary.

In der Fig. 2 werden, abweichend von der Ausführungsform der Fig. 1, die einzelnen gefalteten Druckereiprodukte 12 so geführt, daß die unteren Enden der beiden Hälften der jeweiligen Druckereiprodukte dem jeweiligen Greifer 16 der Fördereinrichtung 10 vorlaufen. In diesem Beispiel wird die Beschriftung mittels des Druckkopfes 24 im Randbereich der vor laufenden Hälfte des gefalteten Druckereiproduktes 12 vorgenommen. Dies bedeutet, daß auch in diesem Beispiel die Greifer 32 mit der Förderanordnung 28 sich mit in etwa der gleichen Geschwindigkeit wie die Fördereinrichtung 10 bewegen, während die Greifer 34 auf der Fördereinrichtung 30 schneller laufen. Diese Ausführungsform der Öffnungseinrichtung 26 entspricht im Detail der Ausführungsform der Fig. 30 der vorhin erwähnten europäischen Patentanmeldung EP-A-0 564 812 der vorliegenden Anmelderin. In Fig. 2, different from the embodiment of the 1, the individual folded printed products 12 out so that the lower ends of the two halves of each Printed products the respective gripper 16 of the conveyor 10 advance. In this example, the label by means of the print head 24 in the edge area of the front current half of the folded printed product 12 made. This means that also in this example the grippers 32 with the conveyor arrangement 28 with approximately the same Moving speed like conveyor 10 while the grippers 34 on the conveyor 30 faster to run. This embodiment corresponds to the opening device 26 in detail of the embodiment of FIG. 30 the previously mentioned European patent application EP-A-0 564 812 of present applicant.

Die Fig. 3 zeigt nunmehr eine weitere Ausführungsform der erfindungsgemäßen Vorrichtung, bei der die Öffnungseinrichtung 26 anders ausgelegt ist. Hier wird die Öffnungseinrichtung nämlich in etwa entsprechend der Öffnungseinrichtung der europäischen Patentanmeldung der vorliegenden Anmelderin mit der Veröffentlichungsnummer EP-A-0 600 216 ausgebildet. Die Öffnungseinrichtung besteht demgemäß aus einem spiralförmig gewickelten Stab 50, dessen mittlere Längsachse 52, welche zugleich die Drehachse der Öffnungseinrichtung darstellt, zumindest im wesentlichen parallel zu der Förderrichtung 14 angeordnet ist. Man erkennt, daß die Steigung zwischen den einzelnen Windungen des schraubenförmigen Stabes 50 im wesentlichen identisch ist mit dem gegenseitigen Abstand der benachbarten Greifer 16 der Fördereinrichtung 10. Die schraubenförmige Öffnungseinrichtung 26 wird mit einer Drehgeschwindigkeit angetrieben, welche dazu führt, daß die jeweils oberen Teile der einzelnen Windungen sich mit der gleichen Geschwindigkeit in Achsrichtung 52 bewegen, wie sich die Greifer der Fördereinrichtung 10 in die Förderrichtung 14 bewegen. Die Windungen des spiralförmigen Stabes 50 halten somit die gefalteten Druckereiprodukte 12 in leicht geöffnetem Zustand. 3 now shows a further embodiment of the Device according to the invention, in which the opening device 26 is designed differently. Here is the opening device namely roughly according to the opening device of the European patent application of the present applicant with publication number EP-A-0 600 216. The Accordingly, the opening device consists of a spiral wound rod 50, the central longitudinal axis 52, which also represents the axis of rotation of the opening device, at least arranged essentially parallel to the conveying direction 14 is. It can be seen that the slope between the individual Windings of the helical rod 50 essentially   is identical to the mutual distance between the neighboring ones Gripper 16 of the conveyor 10. The helical Opening device 26 is at a rotational speed driven, which leads to the respective upper parts of each turn are the same Speed in axis direction 52 move as the Move the gripper of the conveyor 10 in the conveying direction 14. The turns of the spiral rod 50 thus hold the folded printed products 12 in slightly open Status.

Vor dem spiralförmigen Stab 50 angeordnet befindet sich eine Führung 54, welche zur Öffnungseinrichtung gehört. Diese Führung 54 hat einen in Bezug auf die Förderrichtung 14 hinteren Abschnitt 56, der sich innerhalb des schraubenförmigen Stabes 50 erstreckt. Der hintere Abschnitt 56 der Führung 54 geht über einen mittleren Abschnitt 58 der Führung 54, welcher sich der Fördereinrichtung 10 zunehmend nähert, in den vorderen Abschnitt 60 der Führung 54 über, der parallel zu der Fördereinrichtung 10 verläuft und in einem Abstand unterhalb der Fördereinrichtung angeordnet ist, der kleiner ist als die Breite der vorderen und hinteren Hälften der gefalteten Druckereiprodukte 12. Arranged in front of the spiral rod 50 is one Guide 54, which belongs to the opening device. This leadership 54 has a rear in relation to the conveying direction 14 Section 56, which is inside the helical rod 50 stretches. The rear section 56 of the guide 54 goes via a central section 58 of the guide 54, which the conveyor 10 is increasingly approaching, in the front Section 60 of the guide 54 over which is parallel to the Conveyor 10 runs and at a distance below the conveyor is arranged, which is smaller than that Width of the front and back halves of the folded Printed products 12.

Aufgrund dieser Formgebung der Führung 54 werden die leicht geöffnet gehaltenen Hälften der jeweiligen Druckereiprodukte 12 weiter geöffnet in dem Sinne, daß die dem Falz 18 abgewandten Enden 40, 42 der vorderen und hinteren Hälften sich zunehmend voneinander wegbewegen und an der Führung 54 flach anliegen. Der Druckkopf 24 ist dann unterhalb der Führung im vorderen Bereich 61 derselben angeordnet. Die Vorrichtung, so wie bisher beschrieben, kann auch in dieser Form ohne weitere Bestandteile funktionieren. Vorzugsweise ist jedoch zusätzlich eine Klemmeinrichtung 62 vorhanden, welche ebenfalls als eine umlaufende Einrichtung gestaltet ist, die im Bereich des Druckkopfes 24 parallel zu der Förderrichtung 14 der Fördereinrichtung läuft. Die Klemmeinrichtung 62 besteht hier aus einer Fördereinrichtung, welche Paare von Klemmfingern 64, 66 trägt, die im Bereich der Führung 54 voneinander weg bzw. aufeinander zu bewegbar sind. Because of this shape of the guide 54, they are easy held open halves of the respective printing products 12 opened further in the sense that the 18 facing away from the fold Ends 40, 42 of the front and rear halves meet increasingly move away from each other and flat on the guide 54 issue. The print head 24 is then below the guide in front portion 61 of the same. The device, so as previously described, can also be used in this form without further notice Components work. However, preferably is additional   a clamping device 62 available, which also as a rotating facility is designed, which in the area of Printhead 24 parallel to the conveying direction 14 of the conveying device running. The clamping device 62 here consists of a conveyor device, which pairs of clamping fingers 64, 66th carries in the area of the guide 54 away from each other or are movable towards each other.

Im Bereich des hinteren Abschnittes 56 der Führung 54 befindet sich das Klemmfingerpaar 70, dessen Klemmfinger 64 und 66 dicht nebeneinander angeordnet sind. Das Klemmfingerpaar 72, das vor dem Klemmfingerpaar 70 liegt, ist aber bereits in einen Zustand gelangt, wo die Klemmfinger 64 und 66 sich auseinanderbewegt haben. Located in the area of the rear section 56 of the guide 54 the pair of clamping fingers 70, the clamping fingers 64 and 66 are arranged close together. The pair of clamping fingers 72, that is in front of the pair of clamping fingers 70, but is already in one State occurs where the clamping fingers 64 and 66 move apart to have.

Bei dem Klemmfingerpaar 74 ist diese Bewegung bereits beinahe vollständig, so daß der Klemmfinger 64 des Klemmfingerpaares 74 mit dem Klemmfinger 66 des Klemmfingerpaares 72 zu sammenarbeitet und die zwei Hälften des Druckereiproduktes 12A etwas zusammendrängt. With the pair of clamping fingers 74, this movement is almost complete completely so that the clamping finger 64 of the pair of clamping fingers 74 to cooperate with the clamping finger 66 of the pair of clamping fingers 72 and the two halves of the printed product 12A somewhat crowded together.

Bei dem davorliegenden Druckereiprodukt 12B ist der Abstand zwischen den jeweiligen Klemmfingern 66 und 64 kleiner geworden, und dieser Abstand verkleinert sich zunehmend bis zum in Fig. 3 vordersten gefalteten Druckereiprodukt 12D. Durch diese Klemmbewegung der Erfindung wird das Druckereiprodukt gezwungen, im Bereich der Führung 54 eine engere Krümmung einzugehen, wodurch die Eigenelastizität der Druckereiprodukte dafür sorgt, daß die Randbereiche der vorderen und hinteren Hälften flach an der Führung 54 anliegen, so daß ein Flattern dieser Bereiche oder eine unerwünschte Bewegung relativ zum Druckkopf 24 nicht zu befürchten ist. For the printed product 12B in front of it, the distance is between the respective clamping fingers 66 and 64 become smaller, and this distance is getting smaller and smaller Fig. 3 foremost folded printed product 12D. Through this Clamping movement of the invention, the printed product is forced to enter a tighter curve in the area of the guide 54, which creates the inherent elasticity of the printed products ensures that the edge areas of the front and rear Halves lie flat against the guide 54, so that a flutter these areas or an unwanted movement relative to the Printhead 24 is not to be feared.  

Die Fig. 4 und 5 zeigen eine vierte Ausführungsform einer erfindungsgemäßen Vorrichtung, welche ähnlich wie bei der Fig. 3 mit einer Führung 54 arbeitet, die hier aber aus einem statischen Teil und einem bewegten Teil besteht und als Führungseinheit bezeichnet wird. 4 and 5 show a fourth embodiment of a device according to the invention, which is similar to the Fig. 3 works with a guide 54, but here from a static part and a moving part and as Leadership unit is called.

Man sieht aus Fig. 4, daß das hintere Ende 56 der Führungseinheit 54 von den Greifern 16 der Fördereinrichtung 10 einen Abstand aufweist, welcher im wesentlichen der Breite der gefalteten Druckereiprodukte entspricht, die von den Greifern 16 transportiert werden. 4 that the rear end 56 of the guide unit 54 one of the grippers 16 of the conveyor 10 Has a distance which is essentially the width of the folded Printed products matched by the grippers 16 can be transported.

Wie aus der Fig. 5 ersichtlich, besteht die Führungseinheit 54 aus zwei statisch angeordneten Führungsstäben 53, 55, welche in Seitenansicht jeweils die Form der Führung 54 der Ausführung nach Fig. 3 aufweisen, und am vorderen Abschnitt 60 der Führungsstäbe aus einem Förderband 63, das mit der gleichen Geschwindigkeit wie die Fördereinrichtung 10 umläuft. As can be seen from FIG. 5, there is the guide unit 54 from two statically arranged guide rods 53, 55, which in side view, the shape of the guide 54 of the execution 3, and at the front portion 60th of the guide rods from a conveyor belt 63, the same Speed as the conveyor 10 rotates.

Im mittleren Bereich 58 der Führungseinheit 54, wo diese sich der Fördereinrichtung 10 nähert, werden die gefalteten Druckereiprodukte gezwungen, eine zunehmend gekrümmte Form anzunehmen, so daß beispielsweise die gekrümmte Form der einzelnen Druckereiprodukte 12 von der sanft gekrümmten Form 12A in die stärker gekrümmte Form 12B und dann in eine noch stärker gekrümmte Form 12C übergeht. In the central area 58 of the guide unit 54, where it is located the conveyor 10 approaches, the folded Printed products forced an increasingly curved shape assume, for example, that the curved shape of each Printed products 12 of the gently curved shape 12A into the more curved shape 12B and then into an even stronger one curved shape 12C merges.

Zusätzlich zu der Führungseinheit 54 umfaßt die Öffnungseinrichtung 26 für jeden Greifer einen oder mehrere Druckfinger 80, welche sich in den hinteren und mittleren Abschnitten 56 bzw. 58 der Führungseinheit 54 im wesentlichen senkrecht nach unten erstrecken und kürzer sind als der jeweilige Abstand zwischen dem jeweiligen Greifer 16 und der Führungseinheit 54. In addition to the guide unit 54, the opening device comprises 26 one or more pressure fingers for each gripper 80, which is in the back and middle sections 56 and 58 of the guide unit 54 essentially extend vertically downwards and are shorter than the respective one   Distance between the respective gripper 16 and the Guide unit 54.

Der mittlere Greifer 16C der Fördereinrichtung 10 wird am Anfang des vorderen Abschnitts 60 der Führungsbahn 60 entgegen dem Uhrzeigersinn in eine Schräglage geschwenkt, wodurch der Druckfinger 80 mit der hinteren Hälfte des jeweiligen Druckereiproduktes 12C in Berührung gelangt und die Krümmung dieses Druckereiproduktes zunimmt. The middle gripper 16C of the conveyor 10 is at the beginning of the front section 60 of the guideway 60 pivoted clockwise to an oblique position, causing the Pressure finger 80 with the rear half of the respective printed product 12C comes into contact and the curvature of this Print product increases.

Bei der weiteren Bewegung des Greifers 16C in die Stellung des Greifers 16D wird der Druckfinger 80 über einen nicht dargestellten Schwenkmechanismus nach hinten geschwenkt und gelangt in die dargestellte Stellung, in der die hintere Hälfte des Druckereiproduktes 12D gegen das mit der Fördereinrichtung 10 mitlaufende Förderband 63 gedrückt wird. As the gripper 16C moves further into position of the gripper 16D, the pressure finger 80 is not over one pivoting mechanism shown pivoted backwards and arrives in the position shown, in which the rear Half of the printed product 12D against that with the conveyor 10 moving conveyor belt 63 is pressed.

Links und rechts des vorderen Teils 60 der Führungsstäbe 54 befinden sich zwei umlaufende Bänder 82, 83 eines Bandförderers (wie in der Fig. 5 dargestellt), welche in der gleichen Richtung 14, jedoch schneller laufen als die Fördereinrichtung 10 und das mittig angeordnete umlaufende Förderband 63. Diese Anordnung führt dazu, daß die vorderen Hälften der jeweiligen Druckereiprodukte von den hinteren Hälften in Förderrichtung 14 entfernt werden, so daß der Druckkopf 24 die erwünschte Beschriftung im innenliegenden Randbereich der hinteren Hälfte des jeweiligen Druckereiproduktes 12E vornehmen kann. Left and right of the front part 60 of the guide rods 54 there are two revolving belts 82, 83 of a belt conveyor (as shown in Fig. 5), which in the same Direction 14, but run faster than the conveyor 10 and the centrally arranged rotating conveyor belt 63. This arrangement results in the front halves of each Printed products from the rear halves in the conveying direction 14 are removed so that the print head 24 Desired labeling in the inner edge area of the make the rear half of the respective printed product 12E can.

Nach der Beschriftung der jeweiligen Druckereiprodukte können die Greifer 16 zurückgeschwenkt werden in die Lage, die für die Greifer 16A und 16B gezeigt ist. Die Verschwenkung der Greifer und der Druckfinger 80 können durch jeweilige Führungsbahnen gesteuert werden, die der Einfachheit halber nicht gezeigt sind. After labeling the respective print products, you can the grippers 16 are pivoted back into position for grippers 16A and 16B is shown. The pivoting of the The gripper and the pressure finger 80 can be moved through   Guideways are controlled for simplicity are not shown.

Wie aus der Fig. 5, zusammen mit der Fig. 4, hervorgeht, ist die hintere Umlenkachse 84 für die hinteren Umlenkwalzen aller drei Bänder 63, 82, 83 eine gemeinsame Achse und wird frei drehbar gelagert. Für die vorderen Umlenkwalzen der beiden Förderbänder 82, 83 ist wiederum eine gemeinsame Achse 86 vorgesehen, welche als angetriebene Achse ausgeführt ist. Für die vordere Umlenkwalze 88 des umlaufenden Führungsbandes 63 ist eine getrennte Antriebsachse 90 vorgesehen. Aufgrund dieser Anordnung kann die Antriebsachse 90 mit der erforderlichen unterschiedlichen Geschwindigkeit zur Antriebsachse 86 angetrieben werden, um die unterschiedlichen linearen Oberflächengeschwindigkeiten der jeweiligen Förderbänder 63 bzw. 82, 83 zu erzeugen. Die Lage des Druckkopfes 24 kann je nach Lage des zu beschriftenden Bereiches frei gewählt werden, wobei die Förderbänder 63, 82, 83 entsprechend anders angeordnet werden müssen. As can be seen from FIG. 5, together with FIG. 4 the rear deflection axis 84 for the rear deflection rollers of all three bands 63, 82, 83 a common axis and will freely rotatable. For the front deflection rollers of the two Conveyor belts 82, 83 are in turn a common axis 86 provided which is designed as a driven axis. For the front deflecting roller 88 of the rotating guide belt 63 a separate drive axle 90 is provided. Based on these Arrangement can drive axle 90 with the required different speed to the drive axis 86 are driven to the different linear Surface speeds of the respective conveyor belts 63 or 82, 83 to generate. The location of the printhead 24 may vary freely chosen according to the location of the area to be labeled are, the conveyor belts 63, 82, 83 correspondingly different must be arranged.

Statt wie in Fig. 1-4 gezeigt, die Fördereinrichtung 10 im Bereich des Druckkopfes 24 geradlinig zu führen, ist auch eine gekrümmte Bewegungsbahn der Greifer 16 möglich. In diesem Fall muß der Verlauf der Öffnungseinrichtung 26 entsprechend angepaßt werden (gekrümmter statt geradliniger Verlauf). Instead of as shown in Fig. 1-4, the conveyor 10 in Guide the area of the printhead 24 in a straight line is also a curved path of movement of the grippers 16 is possible. In in this case the course of the opening device 26 must be corresponding be adjusted (curved instead of straight Course).
