Definitions

  • the invention lies in the field of printing technology and relates to an arrangement for producing, conveying and further processing tabloids or two and multiple folds.
  • the print products produced by the rotary press are often converted into the form of tabloids, i.e. single or several printed sheets folded once, transferred and thus fed to further work steps.
  • the systems set up for such processing processes are therefore specially adapted to these processing formats.
  • end product is to be understood here to mean printing products as they are present in an arrangement according to the invention, at the exit of one, a forwarding state generally being reached at this exit.
  • starting product is to be understood to mean all printed products as they are fed to an arrangement according to the invention, in order then to be converted into end products, ie generally tabloids. It goes without saying that, for example, two-folds or, if need be, also multiple folds can be supplied as starting products. However, it must then generally be accepted that the deformations mentioned at the beginning of the collar or the second fold already occur.
  • end products as the term is understood here, can also be added to further work steps.
  • tabloids are fed in by a conventional rotation at a certain speed v, this means that they basically have to be further processed at the same speed v.
  • the desired end products generally have a relatively large volume of, for example, 300 pages. This further processing, especially in the case of such extensive end products, sometimes requires relatively slow work steps, so that the required processing capacity cannot be achieved by a long way.
  • complex measures make it possible to increase the capacity within certain limits, for example by providing buffering after the rotation or by dividing the product stream into several individual streams.
  • these measures require a relatively large amount of effort and lead to extensive adjustments to the overall system.
  • a innovative processing and funding process used. Contrary to conventional systems that use serial conveying, for example as a stream of shingles and also process individual printed products serially, the printed products are to be conveyed and processed in groups in clusters. Such a funding process is described in more detail in European patent application No. 89115751.3 (publication No. 358066) and reference is made in full to the details given there for details. This means that the advantages of serial funding can basically be retained, but the processing capacity can be increased significantly.
  • the large processing capacity makes it possible to fold the tabloids into smaller formats only in the course of the last working steps, especially after the tabloids have been cut open, and to economically produce small-format print product formats in offset printing. It must be noted that the new method solves the problem of very different processing capacities of the individual system components.
  • the starting products are fed continuously, preferably clocked, via a conveyor device, here a clock conveyor 21, to a conveyor conversion station 20.
  • This conversion station 20 is used to transfer the starting products, which are serially supplied here in a conventional manner, into printed product clusters.
  • a print product cluster is to be understood here to mean a group of at least two individual print products which are processed in parallel in at least a partial route or a partial process. It should be emphasized that parallel processing is understood to mean functional parallelism , ie the individual printed products of such a cluster are simultaneously subject to identical or functionally related work steps. The mutual arrangement of the printed products of a cluster can vary.
  • the printed products are preferably arranged next to one another and parallel to one another in one plane.
  • the processing of the printed products of each cluster is thus carried out in dependence on the cluster cycle T '.
  • This is in contrast to the division of a conveyor line into two or more parallel lines in printing plant conveyor technology, which may have a geometric parallel guidance, but which alone have the function of reducing the conveyor speed of the feed line.
  • no attention is paid to the simultaneous processing of a cluster, ie a functionally related unit of printed products.
  • This further processing is also to be distinguished from methods which combine several printed products, for example an inserting method, in order to subsequently promote or process them together as a unit.
  • each individual printed product is processed in parallel in a cluster, but each starting product is processed "on its own", nota bene in each case in a functionally dependent manner together with the other printed products of the cluster .
  • the function of this conveying conversion station 20 can also be understood as the conversion of, for example, a clocked and serially conveyed scale stream into a cluster stream, which is conveyed at most with a changed clock.
  • the work steps described above are applied simultaneously to the entire cluster, ie the products contained in a cluster are processed in parallel.
  • Conventional workstations can be used to carry out the individual work steps, with the only requirement that they can process the printed products of an entire cluster at the same time.
  • the size of a cluster can vary depending on the application. The size of a cluster is preferably also selected as a function of the cycle or conveying speed T '(cluster cycle) desired for cluster processing.
  • the cluster cycle T ' can be increased or the conveying speed of the printed product clusters can be reduced, so that the subsequent steps can be carried out at the required speed. It is a great advantage of the method according to the invention that the individual work steps, depending on the size of the clusters, can take place relatively slowly. This enables cost-effective, slow-working individual components, even in very fast overall processes to use. In addition, interface problems that arise due to different processing speeds of the individual components are largely avoided. As can be seen from FIG.
  • the starting products, after they have been converted into a cluster of 4 are cut by a device 22 for cutting the tabloids, then by an envelope feeder 23, a stapling device 24, a folding device 25 and finally by a side trimming device 26 out.
  • the respective work steps can take place in any sequence or can also be suppressed or omitted, so that depending on the function selected, different types of end products are available at the exit 27 for parceling and forwarding.
  • further functions can be provided or the end products can also be fed to a further conveyor device, which allow a subsequent, remote processing process.
  • FIG. 3 now shows a schematic representation of an embodiment of the arrangement according to the invention.

  • the clusters are inside of the processing systems 30 ', 30''transported and / or processed with a cluster cycle T' or T ''. In many cases the cluster clocks T 'and T''will be the same size.

  • each cluster is continued by one work or transport unit for each clock cycle.

For this purpose, the cluster cycle T 'or T''in the processing system is selected such that T' divided by T is less than the number of printed products per cluster. If, on the other hand, the cycle in the processing system is just as large as the ratio of the system cycle multiplied by the number of printed products per cluster, the feed and processing system have an identical conveying capacity.

Abstract

The invention permits an inexpensive, flexible further processing of tabloids to smaller format double and multiple folds. In at least one conveying conversion means with in each case at least one removal station (19', 19'', 19'''), preferably simultaneously several starting products are removed, which are then further processed in parallel as clusters. The clusters are jointly conveyed by conveying means (36-46, 50, 51) and in each case all the printing products of a cluster (2) are simultaneously processed. The method and means have a fundamentally upwardly open processing capacity, even in the case of large printing products.

Description

Die Erfindung liegt im Bereich der Druckereitechnik und bezieht sich auf eine Anordnung zur Herstellung, Förderung und Weiterverarbeitung von Tabloiden oder Zwei- und Mehrfalzen.The invention lies in the field of printing technology and relates to an arrangement for producing, conveying and further processing tabloids or two and multiple folds.

In Druckereibetrieben, insbesondere im Zeitungsbereich, werden häufig die von der Rotationspresse anfallenden Druckprodukte in die Form von Tabloiden, d.h. einzelne oder mehrere einmal gefaltete Druckbogen, übergeführt und so weiteren Arbeitsschritten zugeführt. Die für solche Verarbeitungsprozesse eingerichteten Anlagen sind deshalb speziell auf diese Verarbeitungsformate angepasst. In Bereich der Zeitungsherstellung bedeutet dies, dass standardmässig relativ grossformatige Tabloide mit Abmessungen von bspw. 30 cm · 50 cm in den der Presse nachfolgenden Anlagen vorliegen. Allenfalls werden solche Tabloide nachfolgend in Zwei- oder Dreifalze weiterverarbeitet.In printing plants, particularly in the newspaper sector, the print products produced by the rotary press are often converted into the form of tabloids, i.e. single or several printed sheets folded once, transferred and thus fed to further work steps. The systems set up for such processing processes are therefore specially adapted to these processing formats. In the area of newspaper production, this means that, as standard, relatively large-sized tabloids with dimensions of, for example, 30 cm × 50 cm are present in the systems following the press. At most, such tabloids are subsequently processed in two or three folds.

In neuerer Zeit entsteht immer mehr das Bedürfnis, die Rotationspresse sowie die der Rotation nachgeschalteten Anlagen für ein breiteres Spektrum von Druckereierzeugnissen einzusetzen. Dies liegt unter anderem daran, dass moderne Rotationspressen neben einem Vielfarbendruck eine qualitativ gute Offsetdruckqualität ermöglichen und so vermehrt auch Werbeprospekte, Zeitschriften und andere Druckereiprodukte erzeugt werden können. Gleichzeitig ist es möglich, im Rahmen des Offsetdruckverfahrens kurzfristig Druckplatten herzustellen, und damit eine hohe Aktualität der Druckerzeugnisse zu gewährleisten. Daneben besteht in Anbetracht der relativ hohen Investitionskosten der Druckerpresse und Förderanlagen der Wunsch nach einer möglichst hohen Auslastung sowie Ausnutzung des Systems, d.h. im Bereich der Zeitungsproduktion vor allem auch volle Auslastung am Tag. Hier limitieren jedoch bekannte, der Presse nachgeschaltete Vorrichtungen die Möglichkeiten, da diese für die Weiterverarbeitung der im Offsetdruck üblichen Tabloide oder ev. Zweifalze zu relativ kleinformatigen Prospekten etc. nicht eingesetzt werden können. Ein wesentliches Problem liegt darin begründet, dass ein zusätzlicher Falz am Tabloid oder gar am Zweifalz zu unschönen Falten am Bund führt, die auch nach einer Endbearbeitung bzw. dem Aufschneiden eines Falzes nicht beseitigt werden können. Dieser Nachteil führt im allgemeinen schon beim Falten eines Tabloides zu unakzeptablen Verformungen. Solche qualitativen Einbussen sind höchst unerwünscht. Des weiteren erfordert die Endbearbeitung der Tabloide zu einem klein- oder mittelformatigen Zeitschriften-Endprodukt zusätzliche, zum Teil relativ langsam ablaufende Arbeitsschritte, so dass bei herkömmlichen Verfahren bestehende Förder- und Verarbeitungsanlagen aufwendig ausgebaut werden müssten um in einem bspw. getakteten Betrieb bezüglich Verarbeitungskapazität nicht überfordert zu sein.In recent times, there has been an increasing need to use the rotary press and the downstream machines for a wider range of printed products. This is partly due to the fact that modern rotary presses are next to one Multi-color printing enables high-quality offset printing quality, which means that advertising brochures, magazines and other printed products can also be increasingly produced. At the same time, it is possible to produce printing plates at short notice as part of the offset printing process, thus ensuring that the print products are up to date. In addition, in view of the relatively high investment costs of the printing press and conveyor systems, there is a desire for the highest possible utilization and utilization of the system, ie in the newspaper production sector above all, full utilization during the day. Here, however, known devices downstream of the press limit the possibilities, since they cannot be used for the further processing of the tabloids or possibly two-folds customary in offset printing to form relatively small-format brochures etc. A major problem lies in the fact that an additional fold on the tabloid or even on the double fold leads to unsightly folds on the waistband, which cannot be removed even after finishing or cutting open a fold. This disadvantage generally leads to unacceptable deformations when folding a tabloid. Such losses in quality are highly undesirable. Furthermore, the finishing of the tabloids for a small or medium-sized magazine end product requires additional, sometimes relatively slow-moving work steps, so that existing conveyor and processing systems would have to be extensively expanded in conventional processes in order not to be overwhelmed in terms of processing capacity in a clocked operation, for example to be.

Zur Erhöhung von Weiterverarbeitungskapazitäten werden gemäss dem Stande der Technik Parallelverarbeitungs-Verfahren vorgeschlagen. So werden beispielsweise gemäss der Gebrauchsmuster-Veröffentlichung DE-G-8713282.6 auf einem Förderband in Serie zugeführte Bücher während einem entsprechenden Stopp des Förderbandes auf parallel verlaufende Förderbänder transferiert, um in parallel angeordnete, funktionell an sich voneinander unabhängige Stationen für Falzeinbrennen und Pressen gefördert zu werden.In order to increase further processing capacities, parallel processing methods are proposed according to the prior art. For example, according to the utility model publication DE-G-8713282.6, books fed in series on a conveyor belt are transferred to conveyor belts running in parallel during a corresponding stop of the conveyor belt, in order to be conveyed in parallel, functionally independent stations for fold-in and pressing .

Gemäss der US-Patentschrift Nr. 4519599 werden je zwei noch ungeheftete Hefte von einer kontinuierlich arbeitenden Sammelstrecke erfasst und in einem Heftapparat positioniert, in dem sie gleichzeitig geheftet werden. Das beschriebene Verfahren leitet sich direkt ab aus einem entsprechenden Verfahren zum Heften von Heften mit ca. doppelter Rückenlänge, die nach dem Heften in zwei Hefte zerschnitten werden.According to US Pat. No. 4519599, two booklets that are still unstitched are gripped by a continuously operating collecting section and positioned in a stapler in which they are stapled at the same time. The method described is derived directly from a corresponding method for stapling staples with approximately double back length, which are cut into two staples after stapling.

Für Verarbeitungsgeschwindigkeiten von 40'000 bis 50'000 Exemplaren pro Stunde, wie sie für die on-line Verarbeitung von Tabloiden aus einer Rotationspresse erreicht werden sollen, tauchen bei Anwendung der genannten Verfahren und Vorrichtungen gemäss dem Stande der Technik grundlegende Probleme auf.For processing speeds of 40,000 to 50,000 copies per hour, such as are to be achieved for the online processing of tabloids from a rotary press, fundamental problems arise when using the methods and devices according to the prior art.

Es ist die Aufgabe der Erfindung, eine Anordnung zu schaffen, welche auf möglichst engem Raum eine Weiterverarbeitung und/oder Endverarbeitung von Tabloiden zu auch kleinformatigen Zwischen- oder Endprodukten erlaubt, eine hohe, nach oben grundsätzlich offene Verarbeitungskapazität ermöglicht und sich in ein Gesamtsystem problemlos einbauen lässt, ohne dass die Kapazität von vor- oder nachgeschalteten Anlagen nachteilig beeinträchtigt wird. Es ist ebenfalls die Aufgabe der Erfindung, eine Anordnung zu schaffen, welche die Weiterverarbeitung von Tabloiden grundsätzlich auch ohne zwischengeschaltete Puffervorrichtung, also on-line direkt ab Rotationspresse ermöglicht und bezüglich der Verarbeitungskapazität einfach und kostengünstig ausbaubar ist.It is the object of the invention to provide an arrangement which allows further processing and / or finishing of tabloids into small-sized intermediate or end products in the smallest possible space, enables a high processing capacity which is basically open at the top and can be easily integrated into an overall system leaves without adversely affecting the capacity of upstream or downstream systems becomes. It is also the object of the invention to provide an arrangement which in principle enables the further processing of tabloids even without an intermediate buffer device, that is to say on-line directly from the rotary press, and which can be easily and inexpensively expanded in terms of processing capacity.

Diese Aufgabe wird durch die Anordnung mit den Merkmalen gemäss dem ersten Patentanspruch gelöst.This object is achieved by the arrangement with the features according to the first claim.

Die mittels der Erfindung erreichbaren Verarbeitungsgeschwindigkeiten der Tabloide erlauben es, zusätzliche Faltungen bspw. erst im letzten Arbeitsschritt vorzunehmen. Damit ist es möglich, das Tabloid bereits aufgeschnitten zu falten und unschöne Deformationen zu vermeiden.The processing speeds of the tabloids which can be achieved by means of the invention make it possible to carry out additional folds, for example, only in the last working step. This makes it possible to fold the tabloid open and avoid unsightly deformations.

Unter dem Begriff "Endprodukt" sollen hier Druckerei-Erzeugnisse verstanden werden, wie sie einer erfindungsgemässen Anordnung vorliegen, am Ausgang einer, wobei im allgemeinen an diesem Ausgang ein speditionsreifer Zustand erreicht ist. Dagegen sollen unter dem Begriff "Ausgangsprodukt" sämtliche Druckprodukte verstanden werden, wie sie einer erfindungsgemässen Anordnung zugeführt werden, um dann in Endprodukte übergeführt zu werden, d.h. im allgemeinen Tabloide. Es versteht sich, dass bspw. auch Zweifalze oder allenfalls auch Mehrfalze als Ausgangsprodukte zugeführt werden können. Allerdings muss dann im allgemeinen in Kauf genommen werden, dass die eingangs erwähnten Verformungen am Bund bzw. dem zweiten Falz bereits auftreten. Selbstverständlich können auch Endprodukte, so wie der Begriff hier verstanden wird, noch weiteren Arbeitsschritten zugeführt werden.The term “end product” is to be understood here to mean printing products as they are present in an arrangement according to the invention, at the exit of one, a forwarding state generally being reached at this exit. On the other hand, the term “starting product” is to be understood to mean all printed products as they are fed to an arrangement according to the invention, in order then to be converted into end products, ie generally tabloids. It goes without saying that, for example, two-folds or, if need be, also multiple folds can be supplied as starting products. However, it must then generally be accepted that the deformations mentioned at the beginning of the collar or the second fold already occur. Of course, end products, as the term is understood here, can also be added to further work steps.

Werden von einer herkömmlichen Rotation Tabloide mit einer bestimmten Geschwindigkeit v weiteren Bearbeitungsschritten zugeführt, so bedeutet dies, dass diese grundsätzlich mit derselben Geschwindigkeit v weiterverarbeitet werden müssen. Die angestrebten Endprodukte besitzen im allgemeinen einen relativ grossen Umfang von bspw. 300 Seiten. Diese Weiterverarbeitung, speziell bei solch umfangreichen Endprodukten, erfordert zum Teil relativ langsame Arbeitsschritte, so dass die erforderliche Verarbeitungskapazität bei weitem nicht erreicht werden kann. Durch aufwendige Massnahmen besteht gemäss dem stande der Technik die Möglichkeit, die Kapazität in gewissen Grenzen zu erhöhen, indem bspw. eine Pufferung nach der Rotation vorgesehen wird oder der Produktestrom in mehrere Einzelströme aufgeteilt wird. Diese Massnahmen erfordern jedoch einen relativ grossen Aufwand und führen zu umfangreichen Anpassungen der Gesamtanlage.If tabloids are fed in by a conventional rotation at a certain speed v, this means that they basically have to be further processed at the same speed v. The desired end products generally have a relatively large volume of, for example, 300 pages. This further processing, especially in the case of such extensive end products, sometimes requires relatively slow work steps, so that the required processing capacity cannot be achieved by a long way. According to the state of the art, complex measures make it possible to increase the capacity within certain limits, for example by providing buffering after the rotation or by dividing the product stream into several individual streams. However, these measures require a relatively large amount of effort and lead to extensive adjustments to the overall system.

Entsprechend einem der Erfindungsziele, eine nach oben grundsätzlich offene Verarbeitungskapazität erreichen zu können, wird ein neuartiges Verarbeitungs- und Förderverfahren verwendet. Entgegen herkömmlichen Anlagen, die eine serielle Förderung, bspw. als Schuppenstrom, verwenden und einzelne Druckprodukte auch seriell verarbeiten, sollen die Druckprodukte gruppenweise in Clustern gefördert und bearbeitet werden. Ein solches Förderverfahren ist in der europäischen Patentanmeldung Nr. 89115751.3 (Veröffentlichung Nr. 358066) näher beschrieben und es wird für Einzelheiten vollumfänglich auf die dortigen Ausführungen verwiesen. Damit können die Vorteile der seriellen Förderung grundsätzlich beibehalten werden, die Verarbeitungskapazität jedoch wesentlich erhöht werden. Die grosse Verarbeitungskapazität ermöglicht es, die Tabloide erst im Rahmen der letzten Arbeitsschritte, insbesondere auch nach Aufschneiden der Tabloide, zu kleineren Formaten zu falten und so kleinformatige Druckproduktformate im Offsetdruck wirtschaftlich herzustellen. Es muss beachtet werden, dass das neue Verfahren gleichzeitig das Problem sehr unterschiedlicher Verarbeitungskapazitäten der einzelnen Systemkomponenten löst.In accordance with one of the objectives of the invention, to be able to achieve a processing capacity that is basically open at the top, a innovative processing and funding process used. Contrary to conventional systems that use serial conveying, for example as a stream of shingles and also process individual printed products serially, the printed products are to be conveyed and processed in groups in clusters. Such a funding process is described in more detail in European patent application No. 89115751.3 (publication No. 358066) and reference is made in full to the details given there for details. This means that the advantages of serial funding can basically be retained, but the processing capacity can be increased significantly. The large processing capacity makes it possible to fold the tabloids into smaller formats only in the course of the last working steps, especially after the tabloids have been cut open, and to economically produce small-format print product formats in offset printing. It must be noted that the new method solves the problem of very different processing capacities of the individual system components.

In Figur 1 ist der prinzipielle Ablauf eines entsprechenden Verfahrens dargestellt. Es muss betont werden, dass bei dieser Übersicht wesentliche Elemente der Übersicht halber weggelassen wurden. Der Prozess innerhalb und unmittelbar nach der Druckpresse ist hier nicht näher dargestellt, sondern es wird angenommen, dass Ausgangsprodukte 8, hier Tabloide, mit Fördermitteln bzw. in einer Förderanlage 1 mit einem bestimmten Takt T (Systemtakt) gefördert werden. Die Ausgangsprodukte 8 können mittels dem Verfahren insbesondere in die in der Figur erwähnten Formate der Endprodukte 9 übergeführt werden. Diese Formate werden ermöglicht, indem das Verfahren ein Aufschneiden 11, ein Heften 12, ein Falten 13 sowie ein 2- bzw. 3-Seiten-Beschneiden 14, 15 ermöglichen. Ein wesentliches Element des Verfahrens bildet auch die Förderkonversion 10, auf die anhand von Figur 2 noch näher eingegangen wird.The basic sequence of a corresponding method is shown in FIG. It must be emphasized that essential elements of this overview have been omitted for the sake of clarity. The process inside and immediately after the printing press is not shown in detail here, but it is assumed that starting products 8, here tabloids, are conveyed with funding or in a conveyor system 1 with a certain cycle T (system cycle). The starting products 8 can in particular be converted into the formats of the end products 9 mentioned in the figure using the method. These formats are made possible by the method of cutting open 11, stapling 12, folding 13 and 2 or 3-sided trimming 14, 15. An essential element of the method is also the conveyor conversion 10, which will be discussed in more detail with reference to FIG. 2.

Durch geeignetes Kombinieren dieser Bearbeitungsschritte können bspw. 1/2-formatige, geheftete und be- oder unbeschnittene Endprodukte 9a bzw. 9b, 1/2-formatige, ungeheftete und be- oder unbeschnittene Endprodukte 9d bzw. 9c zusammengestellt werden.By suitably combining these processing steps, for example, 1/2 format, stapled and trimmed or untrimmed end products 9a or 9b, 1/2 format, unstitched and trimmed or untrimmed end products 9d or 9c can be put together.

In Figur 2 ist nun die Förderkonversion anhand eines Beispiels detaillierter dargestellt. Die Ausgangsprodukte werden stetig, vorzugsweise getaktet über eine Fördereinrichtung, hier einen Takttransporteur 21, einer Förder-Konversionsstation 20 zugeführt. Diese Konversionsstation 20 dient dem Überführen der Ausgangsprodukte, die hier in herkömmlicher Weise seriell zugeführt werden, in Druckprodukte-Cluster. Unter einem Druckprodukte-Cluster soll hier eine Gruppe von mindestens zwei einzelnen Druckprodukten verstanden werden, die mindestens über eine Teilstrecke oder einen Teilprozess in paralleler Weise verarbeitet werden. Dabei ist zu betonen, dass unter paralleler Verarbeitung eine funktionale Parallelität verstanden wird, d.h. die einzelnen Druckprodukte eines solchen Clusters gleichzeitig identischen oder funktional zusammenhängenden Arbeitsschritten unterliegen. Die gegenseitige Anordnung der Druckprodukte eines Clusters kann variieren. Vorzugsweise werden die Druckprodukte nebeneinander und parallel zueinander in einer Ebene angeordnet. Die Bearbeitung der Druckprodukte jedes Cluster erfolgt somit in Abhängigkeit des Clustertaktes T'. Dies im Unterschied zur in der Druckerei-Fördertechnik z.T. vorgenommenen Aufteilung einer Förderstrecke in zwei und mehr parallele Bahnen, bei denen wohl eine geometrische Parallelführung vorliegen mag, die aber allein die Funktion haben, die Fördergeschwindigkeit der Zuführstrecke zu reduzieren. Bei solchen Verfahren wird der gleichzeitigen Bearbeitung eines Clusters, d.h. einer funktional zusammengehörigen Einheit von Druckprodukten keine Beachtung geschenkt. Auch ist diese Weiterverarbeitung von Verfahren zu unterscheiden, welche mehrere Druckprodukte zusammenführen, bspw. ein Einsteckverfahren, um diese in der Folge als Einheit gemeinsam zu fördern bzw. zu verarbeiten. Bei dem Verfahren gemäss der Erfindung wird demgegenüber jedes einzelne Druckprodukt zwar parallel in einem Cluster jedoch jedes Ausgangsprodukt "für sich", nota bene jeweils in funktionaler Abhängigkeit zusammen mit den anderen Druckprodukten des Clusters, bearbeitet. Die Funktion dieser Förder-Konversionsstation 20 kann auch als Wandlung eines bspw. getakteten und seriell geförderten Schuppenstromes in einen, allenfalls mit geändertem Takt geförderten, Clusterstrom aufgefasst werden.In Figure 2, the funding conversion is now shown in more detail using an example. The starting products are fed continuously, preferably clocked, via a conveyor device, here a clock conveyor 21, to a conveyor conversion station 20. This conversion station 20 is used to transfer the starting products, which are serially supplied here in a conventional manner, into printed product clusters. A print product cluster is to be understood here to mean a group of at least two individual print products which are processed in parallel in at least a partial route or a partial process. It should be emphasized that parallel processing is understood to mean functional parallelism , ie the individual printed products of such a cluster are simultaneously subject to identical or functionally related work steps. The mutual arrangement of the printed products of a cluster can vary. The printed products are preferably arranged next to one another and parallel to one another in one plane. The processing of the printed products of each cluster is thus carried out in dependence on the cluster cycle T '. This is in contrast to the division of a conveyor line into two or more parallel lines in printing plant conveyor technology, which may have a geometric parallel guidance, but which alone have the function of reducing the conveyor speed of the feed line. In such processes, no attention is paid to the simultaneous processing of a cluster, ie a functionally related unit of printed products. This further processing is also to be distinguished from methods which combine several printed products, for example an inserting method, in order to subsequently promote or process them together as a unit. In contrast, in the method according to the invention, each individual printed product is processed in parallel in a cluster, but each starting product is processed "on its own", nota bene in each case in a functionally dependent manner together with the other printed products of the cluster . The function of this conveying conversion station 20 can also be understood as the conversion of, for example, a clocked and serially conveyed scale stream into a cluster stream, which is conveyed at most with a changed clock.

Wie aus dieser Figur 2 ersichtlich ist, werden die oben beschriebenen Arbeitsschritte, bspw. ein Aufschneiden der Druckprodukte, jeweils gleichzeitig auf das ganze Cluster angewandt, d.h. es erfolgt eine parallele Verarbeitung der in einem Cluster enthaltenen Produkte. Zur Durchführung der einzelnen Arbeitsschritte können herkömmliche Arbeitsstationen verwendet werden, mit der einzigen Bedingung, dass diese jeweils gleichzeitig die Druckprodukte eines ganzen Clusters bearbeiten können. Selbstverständlich ist es auch möglich, für einen Arbeitsschritt eine der Anzahl Druckprodukte pro Cluster entsprechende Zahl von Arbeitsstationen einzusetzen. In dieser Darstellung werden bspw. 4 Druckprodukte je in einer Arbeitsstation gemeinsam verarbeitet. Es versteht sich, dass die Grösse eines Clusters je nach Anwendung variieren kann. Die Grösse eines Clusters wird vorzugsweise auch in Abhängigkeit der für die Clusterbearbeitung gewünschten Takt- oder Fördergeschwindigkeit T' (Clustertakt) gewählt. Sofern verhältnismässig langsame Verarbeitungsschritte zur Bearbeitung der Tabloide nach der Konversionseinrichtung vorgenommen werden sollen, kann der Clustertakt T' erhöht, bzw. die Fördergeschwindigkeit der Druckprodukte-Cluster gesenkt werden, so dass die nachfolgenden Schritte in der erforderlichen Geschwindigkeit durchgeführt werden können. Es ist ein grosser Vorteil des erfindungsgemässen Verfahrens, dass die einzelnen Arbeitsschritte, je nach Wahl der Grösse der Cluster, relativ langsam ablaufen können. Dadurch wird es möglich, auch in sehr schnellen Gesamtprozessen kostengünstige, langsam arbeitende Einzelkomponenten zu verwenden. Ausserdem werden Schnittstellenprobleme, wie sie wegen unterschiedlicher Verarbeitungsgeschwindigkeiten der einzelnen Komponenten auftauchen, weitgehend vermieden. Wie aus Figur 2 ersichtlich ist, werden die Ausgangsprodukte, nachdem sie in 4-er Cluster konvertiert wurden, durch eine Vorrichtung 22 zum Aufschneiden der Tabloide, anschliessend durch einen Umschlaganleger 23, eine Heftvorrichtung 24, eine Falzvorrichtung 25 und schliesslich durch eine Seitenbeschneid-Vorrichtung 26 geführt. Es versteht sich, dass die jeweiligen Arbeitsschritte in beliebiger Abfolge erfolgen können oder auch unterdrückt bzw. ausgelassen werden können, so dass in Abhängigkeit der gewählten Funktion verschiedene Arten von Endprodukten am Ausgang 27 zum paketieren und spedieren vorliegen. Ausserdem können weitere Funktionen vorgesehen werden oder die Endprodukte auch einer weiteren Fördereinrichtung zugeführt werden, die einen anschliessenden, entfernten Bearbeitungsprozess erlauben. Insbesondere ist es auch möglich, innerhalb der Bearbeitungsanlage mehrere Teildruckprodukte (bspw. verschiedene Ausgangsprodukte) zusammenzuführen bzw. zusammenzustecken um so seitenmässig umfangreiche Endprodukte zu erhalten.As can be seen from FIG. 2, the work steps described above, for example cutting open the printed products, are applied simultaneously to the entire cluster, ie the products contained in a cluster are processed in parallel. Conventional workstations can be used to carry out the individual work steps, with the only requirement that they can process the printed products of an entire cluster at the same time. Of course, it is also possible to use a number of workstations corresponding to the number of printed products per cluster for a work step. In this illustration, for example, 4 printed products are processed together in one work station. It goes without saying that the size of a cluster can vary depending on the application. The size of a cluster is preferably also selected as a function of the cycle or conveying speed T '(cluster cycle) desired for cluster processing. If relatively slow processing steps for processing the tabloids are to be carried out after the conversion device, the cluster cycle T 'can be increased or the conveying speed of the printed product clusters can be reduced, so that the subsequent steps can be carried out at the required speed. It is a great advantage of the method according to the invention that the individual work steps, depending on the size of the clusters, can take place relatively slowly. This enables cost-effective, slow-working individual components, even in very fast overall processes to use. In addition, interface problems that arise due to different processing speeds of the individual components are largely avoided. As can be seen from FIG. 2, the starting products, after they have been converted into a cluster of 4, are cut by a device 22 for cutting the tabloids, then by an envelope feeder 23, a stapling device 24, a folding device 25 and finally by a side trimming device 26 out. It goes without saying that the respective work steps can take place in any sequence or can also be suppressed or omitted, so that depending on the function selected, different types of end products are available at the exit 27 for parceling and forwarding. In addition, further functions can be provided or the end products can also be fed to a further conveyor device, which allow a subsequent, remote processing process. In particular, it is also possible to combine or plug together several partial print products (for example different starting products) within the processing system in order to obtain extensive end products in terms of pages.

In dieser Darstellung ist ersichtlich, dass das Heften nach einer 90°-Umlenkung der Druckprodukte erfolgt. Obwohl hier rein geometrisch eine lineare und demnach auf den ersten Blick scheinbar serielle Verarbeitung handelt, liegt faktisch eine parallele Verarbeitung von vier zu einem Cluster zusammengefassten Druckprodukten vor. Eine solche Umlenkung ist z.B. nötig bzw. erwünscht, wenn eine Bearbeitungseinrichtung, hier bspw. die Heftvorrichtung 24, dies der besseren Zugänglichkeit halber erfordert. Gleichzeitig erfolgt auch eine Verarbeitung mit dem Clustertakt T', der grundsätzlich für den ganzen hier dargestellten Verarbeitungsweg gilt. Die Art und Weise der Druckprodukteförderung sowie die Umlenkung um 90° sollen anhand von Figur 5 näher beschrieben werden.In this illustration it can be seen that the stapling takes place after a 90 ° deflection of the printed products. Although here linear processing is purely geometrical and, at first glance, it appears to be serial processing, in fact there is parallel processing of four printed products combined into a cluster. Such a deflection is necessary or desirable, for example, if a processing device, here, for example, the stapling device 24, requires this for better accessibility. At the same time, processing is also carried out with the cluster clock T ', which basically applies to the entire processing path shown here. The manner in which the printed products are conveyed and the deflection by 90 ° will be described in more detail with reference to FIG. 5.

Figur 3 zeigt nun in schematischer Darstellung ein Ausführungsbeispiel der Anordnung gemäss der Erfindung. Aus einer Pufferanordnung 18, bspw. einem Puffer wie er aus der CH-Patentanmeldung 580/88-6 hervorgeht, oder einem Anleger werden Ausgangsprodukte über eine Fördereinrichtung 1 zwei Verarbeitungsstationen 30', 30'' zugeführt. Obwohl die Vorrichtung anhand einer Anlage mit getakteter Zuführung erläutert wird, können die Druckprodukte selbstverständlich in analoger Weise auch mittels anderer Fördermittel kontinuierlich transportiert werden und erst zwecks Konversion in Druckprodukte-Cluster einzeln gegriffen und in eine getaktete Verarbeitung übergeführt werden. Der Förder-Takt der Druckprodukte (Systemtakt) ist mit T bezeichnet. Die Druckprodukte werden je einer Förder-Konversionsstation 20', 20'' zugeführt. In diesem Ausführungsbeispiel werden einer linearen Zuführung an zwei verschiedenen Stellen je Druckprodukte entnommen indem bspw. mit einer Greifeinrichtung einzelne Ausgangsprodukte herausgegriffen werden. Anhand der Figuren 4a und 4b wird dieser Vorgang noch näher erläutert werden. Selbstverständlich kann auch in herkömmlicher Weise mittels einer Weiche eine Aufteilung der Zuführung in zwei Förderstrecken erfolgen, wobei letztere je eine Konversionsstation 20', 20'' beliefern. Die einzelnen Druckprodukte-Cluster 2, hier beispielsweise mit 4 Druckprodukten angedeutet, sind in ihren verschiedenen Transport- bzw. Bearbeitungspositionen dargestellt. Die einzelnen Bearbeitungsmöglichkeiten sind hier, mit Ausnahme von zwei Umschlaganlegern 23', 23'', nicht speziell hervorgehoben und es kann diesbezüglich auf die Figur 2 verwiesen werden. Es sind zwei Zuführeinrichtungen 29', 29'' vorhanden, welche die Umschlaganleger mit Umschlägen beliefern. In analoger Weise können auch, allenfalls über zusätzliche Zuführungen, weitere Teilprodukte zugeführt und mit den Druckprodukten der Cluster in beliebiger Weise zusammengeführt, bspw. eingesteckt werden. Es ist damit möglich ganze Druckprodukte-Cluster, d.h. mehrere Druckprodukte gleichzeitig, zusammenzuführen, was zu sehr hohen Arbeitskapazitäten führt. Die Cluster werden innerhalb der Bearbeitungsanlagen 30', 30'' mit einem Custertakt T' bzw. T'' transportiert und/ oder bearbeitet. Vielfach werden die Clustertakte T' und T'' gleich gross sein. Andererseits kann es, sofern bspw. die Bearbeitungsanlagen 30' und 30'' nicht identische Arbeitsschritte ausführen, wünschenswert sein, die Cluster innerhalb der beiden Anlagen mit einem unterschiedlichen Takt zu fördern. An den beiden Ausgängen 27' und 27'' können wiederum Vorrichtungen 31', 31'' zu Konversion der Cluster vorhanden sein. Auf diese Weise ist in einfacher Weise eine erneute serielle Förderung möglich. Die clusterweise Bearbeitung der Druckprodukte mit einem Clustertakt T' bzw. T'' ermöglicht bspw. eine einfache Rücküberführung in den ursprüngliche Systemtakt T. Damit kann eine solche Bearbeitungsanlage 30, die relativ langsame Arbeitsschritte wie z.B. das Heften umfangreicher Druckprodukte erfordert, problemlos in einen Gesamtablauf integriert werden.Figure 3 now shows a schematic representation of an embodiment of the arrangement according to the invention. Starting products are fed from a buffer arrangement 18, for example a buffer as shown in the CH patent application 580 / 88-6, or an feeder via a conveyor 1 to two processing stations 30 ', 30''. Although the device is explained on the basis of a system with a clocked feed, the printed products can of course be transported continuously in an analogous manner by means of other conveying means and only gripped individually for conversion into printed product clusters and converted into clocked processing. The conveying cycle of the printed products (system cycle) is denoted by T. The printed products are each fed to a conveyor conversion station 20 ', 20''. In this exemplary embodiment, printed products are removed from a linear feed at two different locations per printing product, for example by picking out individual starting products with a gripping device. This process will be explained in more detail with reference to FIGS. 4a and 4b. Of course, the feed can also be divided into two conveyor sections in a conventional manner by means of a switch, the latter each supplying a conversion station 20 ′, 20 ″. The individual printed product clusters 2, indicated here with four printed products, for example, are shown in their various transport or processing positions. With the exception of two envelope feeders 23 ', 23'', the individual processing options are not specifically highlighted here and reference can be made to FIG. 2 in this regard. There are two feed devices 29 ', 29''which supply the envelope feeders with envelopes. In an analogous manner, further sub-products can also be supplied, possibly via additional feeds, and merged with the printed products of the clusters in any manner, for example by inserting them. It is therefore possible to combine entire print product clusters, ie several print products at the same time, which leads to very high work capacities. The clusters are inside of the processing systems 30 ', 30''transported and / or processed with a cluster cycle T' or T ''. In many cases the cluster clocks T 'and T''will be the same size. On the other hand, if, for example, the processing systems 30 'and 30''do not carry out identical work steps, it may be desirable to promote the clusters within the two systems with a different cycle. Devices 31 ', 31''for converting the clusters can in turn be present at the two outputs 27' and 27 ''. In this way, a new serial promotion is possible in a simple manner. The cluster-wise processing of the printed products with a cluster cycle T 'or T''enables, for example, a simple return to the original system cycle T. This means that such a processing system 30, which requires relatively slow work steps, such as stapling extensive printed products, can be easily integrated into an overall process to get integrated.

Das erfindungsgemässe Verfahren eignet sich insbesondere in einem Gesamtsystem mit einem Systemtakt T. Es ist dann ohne weiteres möglich, den Clustertakt T' bzw. T'' mit dem Systemtakt T zu verknüpfen. Durch eine zentrale Steuerung ist es dann bspw. in einfacher Weise möglich, die Förder-Konversionseinrichtungen anzusteuern und die serielle in eine parallele, gruppenweise Bearbeitung überzuführen oder die Cluster wieder in eine serielle Förderung bzw. eine serielle Bearbeitung mit vereinzelten Druckprodukten oder einem Schuppenstrom zu wandeln. Es ist bspw. auch ohne weiteres möglich, auf diese Weise eine Pufferung vorzunehmen.The method according to the invention is particularly suitable in an overall system with a system clock T. It is then easily possible to link the cluster clock T 'or T' 'with the system clock T. A central control then makes it possible, for example, to control the conveyor conversion devices in a simple manner and to convert the serial to parallel, group-wise processing, or to convert the clusters back into serial conveying or serial processing with isolated printed products or a stream of shingles . For example, it is also easily possible to carry out buffering in this way.

Die bereits im Zusammenhang mit Figur 2 erwähnte Änderung bzw. Umlenkung der Transportrichtung innerhalb der Bearbeitungsanlagen 30', 30'' (Fig. 3) um 90° ändert den Takt nicht. Es wird vielmehr bei jedem Taktzyklus jeder Cluster um eine Arbeits- bzw. Transporteinheit weitergeführt. Sofern die Bearbeitungsanlage einen sehr langsamen Vorgang enthält, kann für diesen Arbeitsschritt ein Druckprodukte-Cluster auch für mehr als einen Taktzyklus dort verbleiben. Dazu ist es erforderlich, dass das Verhältnis des Clustertakts T' bzw. T'' zum Systemtakt T so gross ist, dass die Bearbeitungsanlage eine Pufferung erlaubt. Dazu wird der Clustertakt T' bzw. T'' in der Bearbeitungsanlage so gewählt, dass T' dividiert durch T kleiner ist als die Anzahl Druckprodukte pro Cluster. Ist der Takt in der Bearbeitungsanlage hingegen genau so gross wie das Verhältnis des Systemtaktes multipliziert mit der Anzahl Druckprodukte pro Cluster, so besitzen Zuführung und Bearbeitungsanlage eine identische Förderkapazität.The change or redirection of the transport direction within the processing systems 30 ', 30''(FIG. 3) by 90 ° already mentioned in connection with FIG. 2 does not change the cycle. Rather, each cluster is continued by one work or transport unit for each clock cycle. If the processing system contains a very slow process, a print product cluster can be used for this step remain there for more than one clock cycle. For this it is necessary that the ratio of the cluster clock T 'or T''to the system clock T is so large that the processing system allows buffering. For this purpose, the cluster cycle T 'or T''in the processing system is selected such that T' divided by T is less than the number of printed products per cluster. If, on the other hand, the cycle in the processing system is just as large as the ratio of the system cycle multiplied by the number of printed products per cluster, the feed and processing system have an identical conveying capacity.

Figur 4a zeigt nun die Konversion von mittels einem Takttransporteur seriell geförderten Ausgangsprodukten in Cluster zu je drei Druckprodukten. In dieser Ausführungsvariante werden bspw. jedes dritte Exemplar in drei verschiedenen Konversionsstationen 19', 19'', 19''', entnommen. Wie aus der Zeichnung ersichtlich ist, werden in jeder dieser Konversionsstationen je drei Ausgangsprodukte entnommen und nebeneinander als Cluster weitergefördert bzw. verarbeitet. Obwohl die einzelnen Druckprodukte der Übersichtlichkeit halber verschieden schattiert sind, handelt es sich bei den so seriell zugeführten Ausgangsprodukten um identische Erzeugnisse. Vorzugsweise werden die entnommenen Druckprodukte innerhalb eines Clusters nebeneinander und parallel zueinander angeordnet. Es ist leicht möglich mittels herkömmlichen Weichen die in den einzelnen Konversionsstationen zu Clustern zusammengefassten Druckprodukte auf eine gemeinsame Förderstrecke zusammenzuführen um so einen einzigen Clusterstrom zu erhalten.FIG. 4a now shows the conversion of starting products serially conveyed by means of a clock conveyor into clusters of three printed products each. In this embodiment variant, for example, every third specimen is taken from three different conversion stations 19 ', 19' ', 19' ''. As can be seen from the drawing, three starting products are taken from each of these conversion stations and conveyed or processed next to each other as a cluster. Although the individual printed products are shaded differently for the sake of clarity, the initial products fed in this way are identical products. The removed printed products are preferably arranged next to one another and parallel to one another within a cluster. It is easily possible to use conventional switches to combine the printed products combined in the individual conversion stations into clusters on a common conveyor line in order to obtain a single cluster stream.

Figur 4b zeigt ein weiteres Beispiel einer Förder-Konversionseinrichtung, welche den seriellen Schuppenstrom 3 in Cluster zu vier Ausgangsprodukten wandelt. Hier werden in einer ersten Konversionsstation 19' jedes zweite und insgesamt vier Druckprodukte entnommen. In der zweiten Konversionsstation 19'' erfolgt ein gleicher Entnahmeprozess.FIG. 4b shows a further example of a conveyor conversion device which converts the serial scale stream 3 into clusters to four starting products. Here, every second and a total of four printed products are removed in a first conversion station 19 '. In The same conversion process takes place in the second conversion station 19 ″.

Die Entnahme der einzelnen Ausgangsprodukte an den Entnahmestellen erfolgt beispielsweise mit einer Greifeinrichtung gemäss der CH-Patentschrift Nr. 670619 oder einer Einrichtung gemäss der US Patentschrift Nr 4893805 derselben Anmelderin. Wie in Figur 4b gut ersichtlich ist, wird in Abstimmung mit dem Systemtakt, allenfalls nach Vereinzelung, an der jeweiligen Entnahmestelle entweder gleichzeitig mit vier Greifern ein ganzes Cluster zusammengestellt oder aber mit einem einzigen Greifer nacheinander vier Ausgangsprodukte entnommen.The removal of the individual starting products at the removal points takes place, for example, with a gripping device in accordance with Swiss Patent No. 670619 or a device in accordance with US Pat. No. 4893805 by the same applicant. As can be clearly seen in FIG. 4b, in coordination with the system cycle, if necessary after singulation, an entire cluster is either put together simultaneously with four grippers at the respective removal point, or four starting products are removed in succession with a single gripper.

Die Bearbeitungsstationen 30', 30'' bzw. deren Fördermittel 36-46, 50, 51 (Figur 5) sind vorzugsweise quer zur Förderanlage 1 angeordnet, so dass in einfacher Weise mehrere Bearbeitungsstationen bzw. Förder-Konversionsstationen 20', 20'' nebeneinander angeordnet werden können. Obwohl eine gegenseitig rechtwinklige Anordnung der Bearbeitungsanlagen und der Förderanlage 1 meistens vorzuziehen ist, können die Fördermittel 36-46, 50, 51 in einem beliebigen Winkel zur Förderanlage 1 verlaufen.The processing stations 30 ', 30' 'or their conveying means 36-46, 50, 51 (FIG. 5) are preferably arranged transversely to the conveying system 1, so that a plurality of processing stations or conveying conversion stations 20', 20 '' next to one another in a simple manner can be arranged. Although a mutually perpendicular arrangement of the processing systems and the conveyor system 1 is usually preferable, the conveying means 36-46, 50, 51 can run at any angle to the conveyor system 1.

Für bestimmte Arbeitsschritte innerhalb der Bearbeitungsstation 30', 30'' kann es erwünscht sein, die Fördermittel 36-46 um 90° oder einen beliebigen anderen Winkel umzulenken. Wie aus Figur 3 ersichtlich ist, verläuft der Transport der Cluster in diesem Ausführungsbeispiel auf mindestens einem Teilstück 32', 32'' rechtwinklig zur ursprünglichen Transportrichtung nach den Konversionsstationen 20', 20''. Eine solche Umlenkung der Transportrichtung der Cluster ist bspw. erforderlich, wenn dies wegen der Zugänglichkeit bei einer Bearbeitungsstation erforderlich ist.For certain work steps within the processing station 30 ', 30'', it may be desirable to deflect the conveying means 36-46 through 90 ° or any other angle. As can be seen from FIG. 3, the transport of the clusters in this exemplary embodiment runs on at least one section 32 ′, 32 ″ at right angles to the original transport direction after the conversion stations 20 ′, 20 ″. Such a deflection of the direction of transport Cluster is required, for example, if this is necessary due to the accessibility at a processing station.

Figur 5 zeigt nun schematisch ein Ausführungsbeispiel für die Förderung von Druckprodukte-Clustern 2 mit vier Druckprodukten. Mittels einem in dieser Figur nur schematisch dargestellten Anleger 5 werden die letzterem zugeführten Druckprodukte vereinzelt. Es muss beachtet werden, dass der Anleger 5 der Übersichtlichkeit halber stark verkleinert dargestellt wurde. Die Druckprodukte werden diesem über ein hier nicht dargestelltes Fördermittel, bspw. einen Klammertransporteur, zugeführt. Ein solcher Anleger 5 sowie die Art und Weise der Vereinzelung können in herkömmlicher Weise ausgestaltet sein. Die derart vereinzelten Druckprodukte werden nun mittels einem Fördermittel 1, bspw. ebenfalls ein Klammertransporteur, in Richtung des Pfeiles A einer Konversionsstation 19 zugeführt. In diesem Ausführungsbeispiel werden die Cluster 2, die in der Konversionsstation 19 zusammengestellt werden, den der Konversionsstation nachgeschalteten Arbeitsstationen mittels mehreren Kettensträngen 36 zugeführt, welche letzteren hier durch strichpunktierte Linien angedeutet sind.FIG. 5 now shows schematically an exemplary embodiment for the conveyance of printed product clusters 2 with four printed products. The printed products fed to the latter are separated by means of a feeder 5, which is shown only schematically in this figure. It must be noted that investor 5 has been shown in a greatly reduced form for the sake of clarity. The printed products are fed to it via a conveyor, not shown here, for example a clamp conveyor. Such a feeder 5 and the type of separation can be configured in a conventional manner. The printed products thus separated are then fed in the direction of arrow A to a conversion station 19 by means of a conveying means 1, for example also a clamp conveyor. In this exemplary embodiment, the clusters 2, which are assembled in the conversion station 19, are fed to the workstations downstream of the conversion station by means of a plurality of chain strands 36, the latter being indicated here by dash-dotted lines.

Mittels einem ersten Motor 37 wird eine gemeinsame Antriebswelle 39 angetrieben. Die umlaufenden Kettenstränge 36 sind über Umlenkräder der Antriebswelle sowie einer zweiten Welle 40 geführt. Der Antrieb dieser Kettenstränge 36 erfolgt nicht kontinuierlich, sondern mit einem Clustertakt T'. An den Kettensträngen 36 sind in regelmässigen Abständen Fördernocken 41 angeordnet (in der Figur sind nur zwei dieser Fördernocken 41 bezeichnet). Wie aus der Zeichnung ersichtlich ist, sind hier zur Förderung eines Clusters mit je vier Druckprodukten acht solche Kettenstränge 36 vorgesehen. Jedes einzelne Druckprodukt wird durch je zwei Fördernocken 41 in Richtung der Pfeile B transportiert. Da die Kettenstränge 36 in diesem Ausführungsbeispiel gemeinsam angetrieben sind, werden die Druckprodukte zwangsläufig synchron transportiert. Die Druckprodukte liegen vorzugsweise auf Förderplatten auf, die in herkömmlicher Weise ausgestaltet sein können. Durch die Fördernocken 41 ist die parallele Ausrichtung der Druckprodukte in Transportrichtung gewährleistet. Für eine erste Arbeitsstation 6 ist die gegenseitige seitliche Ausrichtung der Druckprodukte schematisch dargestellt. Mittels einem Hubzylinder 42 werden senkrechte Führungsplatten 43 quer zur Transportrichtung in Richtung des Pfeiles C hin- und herbewegt. Dadurch werden die einzelnen Druckprodukte eines Clusters gegen Führungsschienen oder -platten 44 geschoben und so seitlich korrekt positioniert. Gleichzeitig sind bei den einzelnen Arbeitsstationen Gegennocken 45 zur Positionierung der Cluster in Transportrichtung vorgesehen. Die getaktete Förderung und Bearbeitung der Cluster ermöglicht es, dass die einzelnen Druckprodukte eines Clusters jeweils erst bei den einzelnen Arbeitsstationen fein ausgerichtet werden.A common drive shaft 39 is driven by a first motor 37. The circulating chain strands 36 are guided over deflection wheels of the drive shaft and a second shaft 40. These chain strands 36 are not driven continuously, but rather with a cluster cycle T '. Conveying cams 41 are arranged on the chain strands 36 at regular intervals (only two of these conveying cams 41 are designated in the figure). As can be seen from the drawing, eight such chain strands 36 are provided here to promote a cluster with four printed products each. Each individual printed product is transported in the direction of arrows B by two feed cams 41. Since the chain strands 36 in this Embodiment are driven together, the printed products are necessarily transported synchronously. The printed products are preferably on conveyor plates, which can be designed in a conventional manner. The conveying cams 41 ensure the parallel alignment of the printed products in the transport direction. For a first work station 6, the mutual lateral alignment of the printed products is shown schematically. By means of a lifting cylinder 42, vertical guide plates 43 are moved back and forth transversely to the transport direction in the direction of arrow C. As a result, the individual printed products of a cluster are pushed against guide rails or plates 44 and thus correctly positioned laterally. At the same time, counter cams 45 are provided at the individual work stations for positioning the clusters in the transport direction. The timed promotion and processing of the clusters enables the individual print products of a cluster to be fine-tuned at the individual workstations.

Die Umlenkung um 90° ist in diesem Ausführungsbeispiel durch Übergabe an eine umlaufende Greifer-Kette 50, bspw. eine Grip-Kette gemäss dem DE-Patent 2151583. erreicht. Durch bspw. acht Greifer 51, je zwei pro Druckprodukt, werden die Druckprodukte eines Clusters synchron gegriffen. Der Antrieb dieser Greifer-Kette 50 erfolgt über einen zweiten Motor 38. Mittels dieser Greifer-Kette werden die Cluster in Richtung des Pfeiles D weitertransportiert.In this exemplary embodiment, the deflection by 90 ° is achieved by transfer to a rotating gripper chain 50, for example a grip chain according to DE patent 2151583. By means of, for example, eight grippers 51, two for each printed product, the printed products of a cluster are gripped synchronously. This gripper chain 50 is driven by a second motor 38. The clusters are transported further in the direction of arrow D by means of this gripper chain.

Die Figuren 6a und 6b illustrieren die Übergabe der Cluster von den Transportkettensträngen 36 an die Greifer-Kette 50. In dieser Seitenansicht ist eine Förderkette 36 mit einem zugehörigen Umlenkrad 46 auf der Welle 40 erkennbar. Ein einzelner Fördernocken 41, 41′ ist in zwei Positionen dargestellt. Während dem Transport befindet sich der Fördernocken in der Position 41. Mittels einer Steuerkulisse wird der Nocken bei der Übergabe in die Übergabeposition 41' geschwenkt. Die Greiferkette ist im Bereich der Übergabestelle vorzugsweise über eine Kettenführung 53 geführt. Die Greifer 51 der Greifer-Kette 50 befinden sich für die Übernahme jeweils eines Clusters in einer geöffneten Standby-Stellung. Sobald ein Cluster in die entsprechenden Greifer 51 eingreift wird eine Schliesseinrichtung betätigt. Diese kann bspw. eine durch eine Lichtschranke betätigte Steuerkulisse 55 sein, welche die mittels einer Feder 52 unter Vorspannung in Standby-Stellung gehaltenen Greifer in die Schliessposition 51' bringt. Vorzugsweise besitzen die Greifer 51 Anschläge 54 an welche die Druckprodukte bei der Übergabe in Anschlag gebracht werden. Wie aus der Zeichnung ersichtlich ist, besitzen die Greifer 51 in Richtung des Pfeiles E einen gewissen Federweg, damit geringe Linearbewegungen der Cluster in Transportrichtung bei der Übergabe aufgefangen werden können. Figur 6b zeigt zwei Greifer 51 und die Anschläge 54 mit einem ergriffenen Druckprodukt in einer Ansicht von oben. Die Förderrichtung ist durch den Pfeil D dargestellt. Die Übergabe der Druckprodukte 4 wird vorzugsweise durch eine Photozelle überwacht und gesteuert.FIGS. 6a and 6b illustrate the transfer of the clusters from the transport chain strands 36 to the gripper chain 50. In this side view, a conveyor chain 36 with an associated deflection wheel 46 can be seen on the shaft 40. A single conveyor cam 41, 41 'is shown in two positions. The conveyor cam is in position 41 during transport. By means of a control link the cam is pivoted during the transfer into the transfer position 41 '. The gripper chain is preferably guided over a chain guide 53 in the area of the transfer point. The grippers 51 of the gripper chain 50 are in an open standby position for taking over a cluster in each case. As soon as a cluster engages in the corresponding gripper 51, a locking device is actuated. This can be, for example, a control link 55 which is actuated by a light barrier and which brings the grippers, which are held in the standby position under pretension by means of a spring 52, into the closed position 51 '. The grippers 51 preferably have stops 54 to which the printed products are brought to a stop during the transfer. As can be seen from the drawing, the grippers 51 have a certain spring travel in the direction of the arrow E, so that small linear movements of the clusters in the transport direction can be absorbed during the transfer. Figure 6b shows two grippers 51 and the stops 54 with a gripped printed product in a view from above. The direction of conveyance is shown by arrow D. The transfer of the printed products 4 is preferably monitored and controlled by a photo cell.

Die Figuren 7a bis 7c zeigen das Positionieren der Druckprodukte an einer Arbeitsstation in verschiedenen Stadien. Erkennbar sind eine vertikal in Richtung des Pfeiles F bewegbare Positioniereinrichtung 49, ein schematisch angedeuteter, umlaufender Kettenstrang 36 mit mehreren Fördernocken 41. Im dargestellten Bereich sind drei mittels den Fördernocken 41 in Richtung des Pfeiles B transportierte Druckprodukte 4, 4' gezeigt. Die Positioniereinrichtung 49 besitzt mindestens einen Gegennocken 45 und/oder einen Vorpositioniernocken 47. Vorpositioniernocken und Gegennocken erfüllen grundsätzlich dieselbe Aufgabe und sind im allgemeinen gleich ausgestaltet. Die Gegennokken einer Arbeitsstation können aber gleichzeitig auch die Funktion der Vorpositioniernocken der nachfolgenden Arbeitsstation übernehmen bzw. mit diesen identisch sein. Die Gegen- und Vorpositioniernocken sind mit einer gemeinsamen Platte 48 fest verbunden und werden über eine gemeinsamen Verstellzylinder 56 entweder in Positionierstellung (ausgezogene Linie) oder in Förderstellung (gestrichelte Linie) gebracht. Figur 7b zeigt zwei Druckprodukte 4, die einerseits am Gegennocken 45, andererseits am Vorpositioniernocken 47 im Anschlag stehen. Dadurch werden die Druckprodukte ausgerichtet, bevor sie in die eigentliche Arbeitsstation geführt werden, was im getakteten Betrieb schnelle Taktzyklen zulässt. Damit sind diese beiden Druckprodukte in Transportrichtung zur Verarbeitung korrekt positioniert bzw. vorpositioniert. Das bereits in dieser Arbeitsstation, die eine beliebige Funktion wie bspw. Aufschneiden erfüllen kann, bearbeitete Druckprodukt 4′ wird nach links in eine weitere Arbeitsstation weitergefördert. Figur 7c zeigt die Druckprodukte in der Transportphase. Erkenntlich ist eine Führungsschiene 44, die den Druckprodukten 4, 4′ als Führung dient.FIGS. 7a to 7c show the positioning of the printed products at a work station in different stages. A positioning device 49 that can be moved vertically in the direction of arrow F, a schematically indicated rotating chain strand 36 with a plurality of conveying cams 41 can be seen. In the region shown, three printed products 4, 4 ′ conveyed in the direction of arrow B by means of the conveying cams 41 are shown. The positioning device 49 has at least one counter-cam 45 and / or a pre-positioning cam 47. Pre-positioning cams and counter-cams basically perform the same task and are generally of the same design. The opposing cam of a workstation can also take over the function of the prepositioning cams of the subsequent workstation or be identical to them. The counter and preposition cams are firmly connected to a common plate 48 and are brought via a common adjusting cylinder 56 either in the positioning position (solid line) or in the conveying position (dashed line). Figure 7b shows two printed products 4, which are on the one hand on the counter cam 45, on the other hand on the prepositioning cam 47 in the stop. As a result, the printed products are aligned before they are brought into the actual workstation, which allows fast cycle cycles in clocked operation. These two print products are thus correctly positioned or prepositioned in the transport direction for processing. The printed product 4 'already processed in this work station, which can perform any function such as, for example, slicing, is conveyed to the left into a further work station. FIG. 7c shows the printed products in the transport phase. A guide rail 44 can be seen, which serves the printed products 4, 4 'as a guide.

Figur 8 zeigt zur Illustration dieser seitlichen Ausrichtung einen Schnitt durch die Positioniereinrichtung 49 quer zur Förderrichtung. Der Übersichtlichkeit halber sind nur drei Kettenstränge 36 in dieser Figur eingezeichnet. Ein Cluster mit Druckprodukten 4 wird senkrecht zur Zeichnungsebene nach vorne transportiert und ist in Anschlag mit je einem Gegennocken 45 gebracht. Mittels einem Hubzylinder 42 sind vier durch einen oder mehrere Träger 34 gekoppelte Führungsplatten 43 zwecks Seitenrichtung der Druckprodukte 4 quer zur Förderrichtung in Richtung des Pfeiles C hin- und herbewegbar. Die Druckprodukte 4 werden gegen die Führungsschienen 44 geschoben und sind dann zur Bearbeitung sowohl in Transportrichtung als auch quer dazu exakt ausgerichtet.FIG. 8 shows a section through the positioning device 49 transverse to the conveying direction to illustrate this lateral alignment. For the sake of clarity, only three chain strands 36 are shown in this figure. A cluster with printed products 4 is transported forward perpendicular to the plane of the drawing and is brought into abutment with one counter cam 45 each. By means of a lifting cylinder 42, four guide plates 43 coupled by one or more carriers 34 can be moved back and forth transversely to the conveying direction in the direction of arrow C for the purpose of the lateral direction of the printed products 4. The printed products 4 are pushed against the guide rails 44 and are then exactly aligned for processing both in the transport direction and transversely thereto.

Figur 9 zeigt ein weiteres Ausführungsbeispiel für die Betätigung der Gegennocken 45. Mittels eines Exzenters 57 wird der Gegennocken 45 in Abhängigkeit des Fördertaktes in Positionier- bzw. Förderstellung gebracht. Im dargestellten Zeitpunkt befindet sich der Gegennocken 45 oben, d.h. in Positionierstellung, und dient der Ausrichtung eines Druckproduktes 4 in Transportrichtung B.FIG. 9 shows a further exemplary embodiment for the actuation of the counter-cams 45. By means of an eccentric 57, the counter-cam 45 is moved into the positioning or conveying position depending on the conveying cycle brought. At the time shown, the counter cam 45 is at the top, ie in the positioning position, and is used to align a printed product 4 in the transport direction B.

Die Erfindung wird vorzugsweise im Bereich des Offsetdrucks verwendet, kann aber ohne weiteres auch für Tiefdruckverfahren oder andere Druckverfahren eingesetzt werden.The invention is preferably used in the field of offset printing, but can also be used for gravure printing processes or other printing processes.

Eine weitere Ausführungsform der Erfindung sieht vor, dass die Förder-Konversionseinrichtungen die Ausgangsprodukte aus mehreren Anlegern übernehmen und zu Clustern zusammenstellen. So ist es beispielsweise möglich, Cluster aus mehreren Zuführungsbahnen zu bilden. Auf diese Weise können bspw. auch Cluster aus Ausgangsprodukten von zwei oder mehr Rotationspressen oder Wickelstationen zusammengestellt werden. Dazu weist diese Konversionsstation eine der Anzahl Förderanlagen (1) entsprechende Zahl von Greifeinrichtungen auf, so dass gleichzeitig von je einer Förderanlage ein Ausgangsprodukt entnommen werden kann, die dann zu einem Cluster zusammengestellt werden.A further embodiment of the invention provides that the conveyor conversion devices take over the starting products from several investors and combine them into clusters. For example, it is possible to form clusters from several feed paths. In this way, for example, clusters can also be composed of starting products from two or more rotary presses or winding stations. For this purpose, this conversion station has a number of gripping devices corresponding to the number of conveyor systems (1), so that a starting product can be removed from each conveyor system, which are then combined into a cluster.

Selbstverständlich ist es nicht erforderlich, dass der Transport durch einen umlaufenden Kettenstrang oder eine Greifer-Kette bewirkt wird, sondern es können beliebige andere Fördermittel zum Einsatz kommen. Für eine getaktete Zuführung der Cluster in die einzelnen Arbeitsstationen sind allgemein Schleppkettenantriebe und besonders auch eine Gelenkkette geeignet, wie sie im CH-Patent 538 965 beschrieben ist. Für spezifische Anwendung kann die Verarbeitung der Cluster auch ungetaktet, d.h. kontinuierlich im Durchlauf erfolgen.Of course, it is not necessary for the transport to be effected by a rotating chain strand or a gripper chain, but any other means of conveyance can be used. Drag chain drives and, in particular, an articulated chain, as described in Swiss Patent 538,965, are generally suitable for clocked feeding of the clusters into the individual work stations. For specific applications, the processing of the clusters can also be clocked, i.e. done continuously in the run.
