- the first limit concerns the maximum possible cadence with which the printed products can be taken over by the stacking device.
- the second limit concerns the maximum possible cadence, resp. the minimum possible cycle time in which stacks can be removed from the stacking device.
- the production speed in the production line is kept constantly high.
- the production efficiency of the entire production line is still reduced during the formation of small stacks in the stacking device, since although a fluctuation or continuous change in the speed in the production line can be avoided, the overall performance in this method must also be reduced to such an extent. that sufficient time is available for the removal of the stacks. If there is a fault or interruption in the operation of the stacking device, the performance of the entire production line must be reduced to zero.
- the aim is to achieve the high net output with the lowest possible energy consumption and reduced system wear.
- a package sequence is calculated for the stacking device.
- the production plan includes the information about the type and number of collections in each package and the sequence of the packages for shipment, shipment or interim storage.
- the difference in size i.e., in the number of collections in a packet
- the time required to produce the stack of reduced size is achieved by reducing the production speed in the further processing plant of the stacking apparatus. If this difference value exceeds a predefined threshold value, empty positions in the section of the product sequence assigned to the packet are formed in a targeted manner for additional relief of the stacking device or for adaptation to the processing capacity.
- the variation of the operating speed should preferably be achieved with a minimum of speed reduction and acceleration, that is, with very flat ramps.
- the targeted gap formation in the product sequence provides an energy-optimized alternative to strong speed variations, which makes it possible to avoid severe deceleration and acceleration.
- the speed reduction system is not actively decelerated, but the continuous energy losses of the moving machine components are utilized by friction to reduce the speed.
- the system is controlled so that preferably as much energy is left in the system.
- the high mechanical load of individual parts of the system due to the targeted formation of gaps is balanced against the energy consumption due to strong speed variations.
- the pre-determined production plan is optimized to make the packages in their composition, size and order so that they can be loaded onto a transport vehicle in the reverse order of unloading along a distribution route.
- At least one stacking device is provided for processing tip and standard packages, the remaining stacking devices preferably produce packages having the desired maximum standard size.

- a computerized superordinate control device which distributes the total number of end products or collections to be produced, taking into account the specifications from the production plan, to a minimum number of packages.
- the line speed is reduced so much that the stacking device has enough time to produce the top package.
- the difference ⁇ of the size or product number between a preceding packet and a subsequent packet is calculated. If ⁇ exceeds a certain predetermined value, the system can not be slowed down fast enough, that is to say in the intended time window, to the desired lower speed, in order to allow peak packet production.
- the computerized controller starts from the production plan, empty positions have been previously inserted into the product flow, so that only by the slowing down of the pre-stacking printing finishing unit and by the empty positions inserted in the product flow within the time interval that the stacking device requires at least for the production of a package the desired small number of products or collections is delivered.

- the packets that reach the maximum packet size - that is, the so-called standard packets - are assigned according to one or more stacking devices for processing standard packets.
- the computerized control device generates, at least for each stacking device, a product sequence that corresponds to the number and sequence of the end products or collections in the packages to be produced. These individual product sequences are combined into a superimposed product sequence according to the order of the stacking devices or the gathering devices upstream of them, in which the products of the individual product sequences follow one another alternately. The individual product sequences are, so to speak, interlocked or combed together.

- the collections K1 to K4 are discharged and fed to a downstream, not shown in the figure stacking.
- the following product collections K5 to K8 are not dispensed, but returned, thereby allowing the downstream stacking device to supply a product sequence of four complete collections K1 - K4 and then four empty product positions and a top package with four collections instead of a standard package in this case with eight collections form.
- the return In the superimposed product sequence, the return must be taken into account. For the returned four collections, it must be ensured that they are not reapplied with products and / or supplements when they pass through the upper run 53 again.
- the empty positions for these four returned collections K5 to K8 must be moved accordingly backwards.
- the at least one downstream stacking device can thus generate enough time to generate tip packages without generating collections in the waste removal device 68 by generating empty cycle positions.
- the present in the Aus removeer 66 sequence is not already in an identical form in the superimposed product sequence, respectively in the isolated from the superimposed product sequence product sequence for the production of Spitzencuten ago. An advantage of this approach is that the decision to produce a top package and thus the formation of previous empty positions process technology can be moved closer to the stacking device.

Description
Die Erfindung betrifft ein Verfahren zum Betrieb einer Druckweiterverarbeitungsanlage zum Herstellen und Verarbeiten von Druckprodukten, insbesondere zum Bilden von Stapeln oder Paketen aus Druckproduktkollektionen umfassend komplettierte Druckendprodukte wie Zeitschriften und Zeitungen, die vorzugsweise aus einem Hauptprodukt und einer Mehrzahl von Teilprodukten und/oder Beilagen zusammengestellt sind. Die vorliegende Erfindung betrifft zudem eine Druckweiterverarbeitungsanlage zur Durchführung des Verfahrens.The invention relates to a method for operating a print finishing plant for producing and processing printed products, in particular for forming stacks or packages of printed product collections comprising completed printed products such as magazines and newspapers, which are preferably composed of a main product and a plurality of partial products and / or supplements. The present invention also relates to a print finishing plant for carrying out the method.
An die Druckweiterverarbeitung werden mit zunehmender Regionalisierung oder Individualisierung der Produkte immer höhere Anforderungen gestellt. Einerseits müssen zur Steigerung der Rentabilität die Verarbeitungskapazitäten gesteigert werden, respektive mit den gesteigerten Kapazitäten der Rotation Schritt halten, andererseits müssen die Produkte auch für kleinste Zonen reibungslos versandfertig gemacht werden können. Je kleiner die Zonen, das heisst Gebiete mit gleicher Kollektion (zum Beispiel Haupt- und Teilprodukte mit zonenspezifischen Werbebeilagen, Amtsblättern und/oder Veranstaltungshinweisen), desto mehr Spitzenpakete, das heisst Pakete bestehend aus wenigen Produkten, müssen verarbeitet werden. Da sich der Bearbeitungszyklus bei den bekannten Abstapelvorrichtungen, Bindern etc. nicht unter eine Zyklusdauer von derzeit etwa 2 Sekunden reduzieren lässt, wird für die Herstellung eines Paketes mit einigen wenigen Druckprodukten oder Kollektionen von Druckprodukten genauso viel Zeit benötigt wie für ein komplettes Paket mit der vollen Anzahl von Druckprodukten oder Kollektionen, die je nach Dicke der Druckprodukte oder Kollektionen bei 20 bis 40 oder mehr liegen kann. Je mehr kleine Stapel oder Pakete gebildet werden müssen, desto ineffizienter arbeiten die bekannten Anlagen zur Druckweiterverarbeitung.Print finishing is becoming increasingly demanding with increasing regionalization or individualization of the products. On the one hand, in order to increase profitability, processing capacities have to be increased, respectively, keeping pace with the increased capacities of rotation, on the other hand, the products must be made smoothly ready for shipment even for the smallest zones. The smaller the zones, ie areas with the same collection (for example main and partial products with zone-specific advertising supplements, gazettes and / or event announcements), the more top packages, ie packages consisting of a few products, must be processed. Since the processing cycle in the known stacking devices, binders, etc., can not be reduced below a cycle duration of currently about 2 seconds, it takes just as much time to produce a package with a few printed products or collections of printed products as for a complete package with the full one Number of printed products or collections, which may be 20 to 40 or more, depending on the thickness of the printed products or collections. The more small stacks or packages have to be formed, the more inefficient the known systems for postpress processing.

Unabhängig von der Grösse der in der Stapelvorrichtung zu bildenden Stapel wird die Produktionsgeschwindigkeit in der Fertigungslinie konstant hoch gehalten. Die Produktionsleistung der gesamten Fertigungslinie ist während der Bildung von kleinen Stapeln in der Stapelvorrichtung jedoch nach wie vor reduziert, da zwar eine Schwankung oder laufende Veränderung der Geschwindigkeit in der Fertigungslinie vermieden werden kann, die gesamte Leistung bei diesem Verfahren jedoch auch soweit reduziert werden muss, dass für die Ausförderung der Stapel genügend Zeit zur Verfügung steht. Kommt es zu einer Störung oder einer Unterbrechung im Betrieb der Stapelvorrichtung, so muss die Leistung der gesamten Fertigungslinie auf Null reduziert werden.Regardless of the size of the stack to be formed in the stacking device, the production speed in the production line is kept constantly high. However, the production efficiency of the entire production line is still reduced during the formation of small stacks in the stacking device, since although a fluctuation or continuous change in the speed in the production line can be avoided, the overall performance in this method must also be reduced to such an extent. that sufficient time is available for the removal of the stacks. If there is a fault or interruption in the operation of the stacking device, the performance of the entire production line must be reduced to zero.
Es ist daher eine Aufgabe der vorliegenden Erfindung, ein verbessertes Betriebsverfahren mit einer, zwei oder mehr Abstapelvorrichtungen anzubieten, das es ermöglicht, dass grosse Stückzahlen von Druckprodukten und/oder Kollektionen mit höchstmöglicher Systemeffizienz zu Stapeln oder Paketen zusammengestellt werden können, so dass die Herstellung von kleinen Stapeln oder Paketen (sogenannten Spitzenpaketen) die Gesamtleistung einer Druckweiterverarbeitungsanlage auch bei hohem Individualisierungs- oder Regionalisierungsgrad optimiert werden kann. Dabei soll die hohe Nettoleistung mit einem möglichst geringen Energieverbrauch und unter verringertem Anlagenverschleiss erzielt werden.It is therefore an object of the present invention to provide an improved method of operation with one, two or more stacking devices which enables large numbers of printed products and / or collections to be stacked or stacked with the highest possible system efficiency, thus enabling the production of Small stacks or packages (so-called top packages), the overall performance of a print finishing plant can be optimized even at a high degree of individualization or regionalization. The aim is to achieve the high net output with the lowest possible energy consumption and reduced system wear.
Es ist eine weitere Aufgabe der vorliegenden Erfindung eine Vorrichtung und ein Verfahren zur Regelung des Zuförderns von Druckprodukten zu Abstapelvorrichtungen vorzuschlagen, welche zumindest einige Nachteile der bekannten Vorrichtungen und Verfahren nicht aufweisen. Es ist insbesondere eine Aufgabe der vorliegenden Erfindung eine Vorrichtung und ein Verfahren zur Regelung einer Druckweiterverarbeitungsanlage zur Verfügung zu stellen, die mindestens einen Förderer zum Zufördern von Druckprodukten zu Zusammentrag-Vorrichtungen umfassen, wobei die Zusammentrag-Vorrichtungen Abstapelvorrichtungen vorgeschaltet sind.It is a further object of the present invention to provide an apparatus and method for controlling the feeding of printed products to stacking apparatuses which do not have at least some disadvantages of the known apparatuses and methods. It is a particular object of the present invention to provide an apparatus and method for controlling a print finishing line comprising at least one conveyor for feeding printed products to collating devices, the collating devices being preceded by stacking devices.
Gemäss der vorliegenden Erfindung werden diese Ziele durch die Elemente der unabhängigen Ansprüche erreicht. Weitere vorteilhafte Ausführungsformen gehen ausserdem aus den abhängigen Ansprüchen und der Beschreibung hervor.According to the present invention, these objects are achieved by the elements of the independent claims. Further advantageous embodiments are also evident from the dependent claims and the description.
Die oben genannten Ziele werden durch die vorliegende Erfindung insbesondere dadurch erreicht, dass die zu verarbeitenden Druckprodukte unter Variation der Betriebsgeschwindigkeit der Druckweiterverarbeitungsanlage gemäss einem vorgegebenen Produktionsplan zu einer Sequenz von herzustellenden Produkten und/oder Kollektionen zusammengestellt und diese zu Stapeln (im Folgenden auch Pakete genannt) mit einer individuell vorgegebenen Grösse verarbeitet werden.The above-mentioned objects are achieved by the present invention in particular by compiling the printed products to be processed while varying the operating speed of the print finishing plant according to a predetermined production plan into a sequence of products and / or collections to be produced and stacking them (hereinafter also referred to as packages). be processed with an individually predetermined size.
Ausgehend vom vorgängig festgelegten Produktionsplan und der maximalen Paketgrösse, das heisst der Anzahl von Produkten und/oder Kollektionen in einem Paket, wird für die Abstapelvorrichtung eine Paketsequenz errechnet. Der Produktionsplan umfasst die Information über die Art und Anzahl von Kollektionen in jedem Paket und die Sequenz der Pakete zum Versand, zur Verladung oder zum Zwischenlagern. Wiederum ausgehend von der Paketsequenz wird die Differenz in der Grösse (d.h. in der Anzahl von Kollektionen in einem Paket) der aufeinanderfolgenden Pakete in der Sequenz ermittelt. Nimmt die Anzahl der Kollektionen in einem nachfolgenden Paket ab, so wird durch eine Verringerung der Produktionsgeschwindigkeit in der Weiterverarbeitungsanlage der Abstapelvorrichtung die benötigte Zeit verschafft um den Stapel reduzierter Grösse herzustellen. Überschreitet dieser Differenzwert einen vorgegebenen Schwellenwert, so werden zur zusätzlichen Entlastung der Abstapeleinrichtung, respektive zur Anpassung an die Verarbeitungskapazität gezielt Leerpositionen in dem, dem Paket zugewiesenen, Abschnitt der Produktsequenz gebildet.Based on the previously defined production plan and the maximum package size, ie the number of products and / or collections in a package, a package sequence is calculated for the stacking device. The production plan includes the information about the type and number of collections in each package and the sequence of the packages for shipment, shipment or interim storage. Again, starting from the packet sequence, the difference in size (i.e., in the number of collections in a packet) of the successive packets in the sequence is determined. If the number of collections decreases in a subsequent package, the time required to produce the stack of reduced size is achieved by reducing the production speed in the further processing plant of the stacking apparatus. If this difference value exceeds a predefined threshold value, empty positions in the section of the product sequence assigned to the packet are formed in a targeted manner for additional relief of the stacking device or for adaptation to the processing capacity.
Generell soll zur Erreichung einer hohen Systemeffizienz die Variation der Betriebsgeschwindigkeit vorzugsweise mit einem Minimum an Geschwindigkeitsreduktion und Beschleunigung, das heisst mit sehr flach ausgebildeten Rampen, erreicht werden. Durch die gezielte Lückenbildung in der Produktsequenz steht eine energieoptimierte Alternative zu starken Geschwindigkeitsvariationen zur Verfügung, die es erlaubt starkes Abbremsen und Beschleunigen zu vermeiden. Vorzugsweise wird die Anlage zur Geschwindigkeitsreduktion nicht aktiv abgebremst, sondern es werden die kontinuierlichen Energieverluste der bewegten Maschinenkomponenten durch Reibung zum Verringern der Geschwindigkeit genutzt. Dabei wird die Anlage derart gesteuert, dass vorzugsweise möglichst viel Energie im System belassen wird. Die hohe mechanische Belastung einzelner Anlagenteile durch die gezielte Lückenbildung wird abgewogen gegen den Energieverbrauch durch starke Geschwindigkeitsvariationen.In general, to achieve a high system efficiency, the variation of the operating speed should preferably be achieved with a minimum of speed reduction and acceleration, that is, with very flat ramps. The targeted gap formation in the product sequence provides an energy-optimized alternative to strong speed variations, which makes it possible to avoid severe deceleration and acceleration. Preferably, the speed reduction system is not actively decelerated, but the continuous energy losses of the moving machine components are utilized by friction to reduce the speed. The system is controlled so that preferably as much energy is left in the system. The high mechanical load of individual parts of the system due to the targeted formation of gaps is balanced against the energy consumption due to strong speed variations.
Es ist bekannt, dass gattungsgleiche Anlagen zur Druckweiterverarbeitung bei einem Notstopp innerhalb von etwa 1 Sekunde vom Betrieb mit der höchsten Verarbeitungsgeschwindigkeit, respektive dem höchsten Durchsatz, zum Stehen kommen müssen. In einem Diagramm, in der Durchsatz in Stück/Kollektionen gegen die Zeit aufgetragen ist, stellt der Notstopp die steilste Rampe nach unten dar. Bei einem solchen Notstopp ist es jedoch nicht immer möglich alle Anlagenteile koordiniert herunterzufahren. Dies bedingt einen zusätzlichen Aufwand zum synchronisieren aller Anlagenteile beim erneuten Anfahren nach einem Notstopp. Bei einem gezielten Herunterfahren der Weiterverarbeitungsanlage kann innerhalb von wenigen Sekunden die Verarbeitungsgeschwindigkeit vom Maximum auf Null reduziert werden, ohne dass die einzelnen Anlagenteile den Takt verlieren. Mit dieser negativen Beschleunigung kann die Verarbeitungsgeschwindigkeit maximal reduziert werden um die Abstapeleinrichtung zur Herstellung von Spitzenpaketen zu entlasten, ohne dass in der Anlage der Takt verloren geht. Wenn die Herstellung von einzelnen Spitzenpaketen eine stärkere Geschwindigkeitsreduktion erfordert, werden gemäss der vorliegenden Erfindung gezielt Leerpositionen in den Produktestrom eingefügt. Der Produktdurchsatz lässt sich damit noch weiter reduzieren, ohne dass die Anlagengeschwindigkeit weiter abnimmt. Die Überlagerung von diesen zwei Massnahmen erlaubt es also eine Abstapeleinrichtung zur Herstellung kleinster Spitzenpakete zu entlasten, ohne die Anlage mechanisch stark zu belasten, sondern einen harmonischen Anlagenbetrieb beizubeahalten.It is known that generic equipment for post-press processing must come to an end within about 1 second of operation at the highest processing speed, and highest throughput, respectively. In a diagram in which throughput in pieces / collections is plotted against time, the emergency stop represents the steepest ramp down. In such an emergency stop, however, it is not always possible to shut down all system parts in a coordinated manner. This requires an additional effort to synchronize all parts of the system when starting again after an emergency stop. With a targeted shutdown of the further processing system, the processing speed can be reduced from maximum to zero within a few seconds without the individual system parts losing their time. With this negative acceleration, the processing speed can be reduced as much as possible to relieve the stacking device for the production of tip packages without losing the clock in the system. If the production of individual tip packages requires a greater speed reduction, then in accordance with the present invention, empty positions are deliberately introduced into the product stream. The product throughput can be reduced even further without the system speed decreasing further. The superimposition of these two measures thus makes it possible to relieve a stacking device for the production of smallest tip packages, without mechanically stressing the system, but to maintain a harmonious plant operation.
Der vorgängig festgelegte Produktionsplan ist darauf hin optimiert, dass die Pakete in ihrer Zusammensetzung, Grösse und Reihenfolge derart hergestellt werden, dass sie in der umgekehrten Reihenfolge des Abladens entlang einer Verteilroute auf ein Transportfahrzeug geladen werden können.The pre-determined production plan is optimized to make the packages in their composition, size and order so that they can be loaded onto a transport vehicle in the reverse order of unloading along a distribution route.
Gemäss der vorliegenden Erfindung kommen mindestens eine, in vorteilhaften Ausführungsformen aber auch mehr, Abstapeleinrichtungen zum Einsatz. Beim Einsatz von zwei oder mehr Abstapeleinrichtungen hat es sich als vorteilhaft erwiesen ausgehend vom vorgängig festgelegten Produktionsplan und der maximalen Paketgrösse, das heisst der Anzahl von Kollektionen in einem Paket, die eine maximale Effizienz beim Betrieb der Abstapeleinrichtung ermöglichen, für jede Abstapelvorrichtung eine separate Produktsequenz zu errechnen. Der Produktionsplan umfasst bei diesen Ausführungsformen nicht nur die Information über die Art und Anzahl von Kollektionen in jedem Paket und die Sequenz der Pakete zum Versand, zur Verladung oder zum Zwischenlagern, sondern zusätzlich noch die Information welcher Abstapeleinrichtung eine Kollektion zugeordnet ist.According to the present invention, at least one, in advantageous embodiments but also more, stacking devices are used. When using two or more stacking devices, it has proved to be advantageous starting from the previous defined production plan and the maximum package size, that is, the number of collections in a package that allow maximum efficiency in operation of the stacking device to calculate a separate product sequence for each stacking device. The production plan in these embodiments includes not only the information about the type and number of collections in each package and the sequence of packages for shipping, loading or storage, but also the information which stacking device is associated with a collection.
Bei Anlagen mit mehr als einer Abstapeleinrichtung ist vorzugsweise mindestens eine Abstapeleinrichtung für die Verarbeitung von Spitzen- und Normpaketen vorgesehen, die übrigen Abstapeleinrichtungen stellen vorzugsweise Pakete mit der gewünschten maximalen Normgrösse her. Es wird also mindestens eine Stapelvorrichtung "genutzt" um mit verringerter Nettoleistung Spitzen- und Normpakete herzustellen. Dem stehen jene Abstapelvorrichtungen gegenüber, die mit hoher Effizienz Pakete der gewünschten Normgrösse herstellen. Vorzugsweise ist in der erfindungsgemässen Anlage zur Druckweiterverarbeitung der mindestens einen Abstapeleinrichtung für die Verarbeitung von Spitzenpaketen eine Zusammentrag-Vorrichtung vorgeschaltet.In systems with more than one stacking device, preferably at least one stacking device is provided for processing tip and standard packages, the remaining stacking devices preferably produce packages having the desired maximum standard size. Thus, at least one stacking device is "used" to produce peak and standard packages with reduced net power. This is contrasted with those stacking devices which produce packages of the desired standard size with high efficiency. Preferably, in the system according to the invention for further printing, the at least one stacking device for processing tip packages is preceded by a collating device.
Auch den Abstapelvorrichtungen die mit maximaler Auslastung Pakete der gewünschten Normgrösse herstellen ist mindestens eine Zusammentrag-Vorrichtung vorgeschaltet. Mittels eines vorgeschalteten Zuförderers, vorzugsweise eines Rundlaufs, lassen sich vorzugsweise taktsynchron alle Zusammentrag-Vorrichtungen mit Hauptprodukten und eingesteckten Vorprodukten versorgen. Haupt- und Vorprodukte stammen aus einem weiteren wiederum vorgeschalteten Anlagenteil, zum Beispiel einer Einstecktrommel, in der eine gewünschte Anzahl von Vorprodukten in ein Hauptprodukt eingesteckt werden. Im offline Betrieb werden Haupt- und Vorprodukte von Speichereinrichtungen mittels geeigneter Zuführförderer, zum Beispiel bekannter Lagentakter der Anmelderin, der Einstecktrommel zugeführt.At least one gathering device is also connected upstream of the stacking devices which produce packages of the desired standard size with maximum utilization. By means of an upstream feed conveyor, preferably a concentricity, it is possible, preferably in clock-synchronized fashion, to supply all the gathering devices with main products and inserted precursors. Main products and primary products come from a further upstream part of the plant, for example a plug-in drum, in which a desired number of precursors are inserted into a main product. In off-line operation, main and preliminary products of storage devices are fed to the insertion drum by means of suitable feed conveyors, for example the known character of the applicant.
Ausgehend vom vorgegebenen Produktionsplan wird in einer computerisierten übergeordneten Steuereinrichtung eine überlagerte Produktsequenz berechnet, die die gesamte Anzahl der herzustellenden Endprodukte oder Kollektionen unter Berücksichtigung der Vorgaben aus dem Produktionsplan auf eine minimale Anzahl von Paketen verteilt. Zur Herstellung von Paketen, die die maximale Paketgrösse nicht erreichen - die sogenannten Spitzenpakete - wird die Anlagengeschwindigkeit so weit reduziert, dass der Abstapeleinrichtung genügend Zeit bleibt um das Spitzenpaket herzustellen. Es wird hierzu die Differenz Δ der Grösse oder Produktanzahl zwischen einem vorhergehenden Paket und einem nachfolgenden Paket berechnet. Überschreitet Δ einen bestimmten vorgegebenen Wert, so kann die Anlage nicht schnell genug, das heisst im vorgesehenen Zeitfenster nicht auf die gewünschte geringere Geschwindigkeit, verlangsamt werden um die Spitzenpaketproduktion zu erlauben. In einem solchen Fall sind ausgehend vom Produktionsplan vorgängig Leerpositionen in den Produktestrom eingefügt worden, so dass durch die Verlangsamung der, der Abstapeleinrichtung vorgeschalteten Druckweiterverarbeitungsanlage und durch die gezielt im Produktestrom eingefügten Leerpositionen innerhalb des Zeitintervalls, das die Abstapeleinrichtung mindestens zur Herstellung eines Pakets benötigt, nur die gewünschte geringe Anzahl von Produkten oder Kollektionen angeliefert wird. Die computerisierte Steuereinrichtung generiert eine Produktsequenz, die Anzahl und Reihenfolge der Leerpositionen zwischen den Endprodukten oder Kollektionen entsprechend der herzustellenden Pakete umfasst.Based on the given production plan, a superimposed product sequence is calculated in a computerized superordinate control device, which distributes the total number of end products or collections to be produced, taking into account the specifications from the production plan, to a minimum number of packages. For the production of packages that do not reach the maximum package size - the so-called top packages - the line speed is reduced so much that the stacking device has enough time to produce the top package. For this purpose, the difference Δ of the size or product number between a preceding packet and a subsequent packet is calculated. If Δ exceeds a certain predetermined value, the system can not be slowed down fast enough, that is to say in the intended time window, to the desired lower speed, in order to allow peak packet production. In such a case, starting from the production plan, empty positions have been previously inserted into the product flow, so that only by the slowing down of the pre-stacking printing finishing unit and by the empty positions inserted in the product flow within the time interval that the stacking device requires at least for the production of a package the desired small number of products or collections is delivered. The computerized controller generates a product sequence that includes the number and order of empty positions between the end products or collections according to the packages to be manufactured.
Verfügt die Druckweiterverarbeitungsanlage über zwei oder mehr Abstapeleinrichtungen, so lassen sich alle diese Einrichtungen gemäss dem vorgängig beschriebenen Verfahren betreiben. Es kann gemäss bevorzugten Ausführungsformen aber auch einer Abstapeleinrichtung die Verarbeitung von Spitzen- und Normpaketen zugewiesen werden. Die Pakete, die die maximale Paketgrösse erreichen - das heisst die sogenannten Normpakete - werden entsprechend einer oder mehreren Abstapeleinrichtungen für die Verarbeitung von Normpaketen zugewiesen. Die computerisierte Steuereinrichtung generiert zumindest für jede Abstapeleinrichtung eine Produktsequenz, die der Anzahl und Reihenfolge der Endprodukte oder Kollektionen in den herzustellenden Paketen entspricht. Diese einzelnen Produktsequenzen werden entsprechend der Reihenfolge der Abstapeleinrichtungen oder der ihnen vorgeschalteten Zusammentrag-Vorrichtungen zu einer überlagerten Produktsequenz vereinigt, bei der die Produkte der einzelnen Produktsequenzen einander abwechselnd folgen. Die einzelnen Produktsequenzen sind sozusagen ineinander verzahnt oder eingekämmt.If the print finishing plant has two or more stacking devices, all these devices can be operated in accordance with the previously described method. It can be assigned according to preferred embodiments but also a stacking the processing of peak and standard packets. The packets that reach the maximum packet size - that is, the so-called standard packets - are assigned according to one or more stacking devices for processing standard packets. The computerized control device generates, at least for each stacking device, a product sequence that corresponds to the number and sequence of the end products or collections in the packages to be produced. These individual product sequences are combined into a superimposed product sequence according to the order of the stacking devices or the gathering devices upstream of them, in which the products of the individual product sequences follow one another alternately. The individual product sequences are, so to speak, interlocked or combed together.
Müssen zum Beispiel drei Abstapelvorrichtungen, respektive drei vorgeschaltete Zusammentrag-Vorrichtungen, mit Produkten versorgt werden, so wird eine überlagerte Produktsequenz generiert, bei der jedes dritte Produkt derselben Abstapelvorrichtung, respektive derselben vorgeschalteten Zusammentrag-Vorrichtungen, zugeordnet ist. Diese eindeutige Zuordnung ermöglicht es, alle wesentlichen Anlagenteile taktsynchron zu betreiben, wobei je nach Grösse der Spitzenpakete nicht alle Taktpositionen in der Produktsequenz der Abstapelvorrichtung für die Herstellung der Spritzenpakete mit Produkten belegt sind. Dank der überlagerten Produktsequenz lässt sich in der erfindungsgemässen Druckweiterverarbeitungsanlage ein einziger Produktstrom bilden und mit den selben Anlagenteilen verarbeiten, der ineinander gefügt die Produktsequenzen für Norm- und Spitzenpakete umfasst. Eine Aufspaltung der Produktströme erfolgt vorzugsweise erst vor deren Zuführung zu den Abstapelvorrichtungen oder den ihnen vorgeschalteten Zusammentrag-Vorrichtungen. Dies erlaubt es die Anlagenteile mit maximaler Effizienz zu nutzen, da die Produktströme für die Herstellung von Normal- und Spitzenpaketen erst dann aufgeteilt werden, wenn dies unbedingt notwendig ist.If, for example, three stacking devices, respectively three upstream gathering devices, have to be supplied with products, then a superimposed product sequence is generated in which every third product is assigned to the same stacking device, or the same upstream gathering devices. This unique assignment makes it possible to operate all the essential system parts isochronous, wherein not all clock positions in the product sequence of the stacking device for the production of syringe packages are occupied with products depending on the size of the tip packages. Thanks to the superimposed product sequence, a single product stream can be formed in the pressure-finishing plant according to the invention and processed with the same parts of the plant which, when combined, comprise the product sequences for standard and tip packages. A splitting of the product streams preferably takes place only before they are fed to the stacking devices or the gathering devices connected upstream of them. This allows the system parts to be used with maximum efficiency, since the product streams for the production of normal and tip packages are not divided unless absolutely necessary.
Gemäss einer weiteren Ausführungsform des erfinderischen Verfahrens ist der mindestens einen Abstapeleinrichtung eine Zusammentrag-Vorrichtungen vorgeschaltet, die über die Fähigkeit zum Rückführen der Produkte verfügt. Solche Vorrichtungen sind von der Anmelderin unter dem Handelsnamen Flystream bekannt und gattungsgleich zum Beispiel in der Offenlegungsschrift
Das Rückführen von Produktkollektionen in der Zusammentrag-Vorrichtung ist in der Produktsequenz zu berücksichtigen. Es führt dazu, dass die Reihenfolge der Produkte, die der Zusammentrag-Vorrichtung zugeführt werden, nicht der Reihenfolge der Produkte/Produktekollektionen in den daraus hergestellten Spitzenpakete entspricht.The recycling of product collections in the collating apparatus must be considered in the product sequence. As a result, the order of the products fed to the collating apparatus does not correspond to the order of the products / product collections in the tip packs made therefrom.
Nach Durchlaufen der Zusammentragstrecke werden die zusammengetragenen Produktkollektionen gemäss bevorzugter Ausführungsformen in Folie eingeschweisst, an Ausförderer, zum Beispiel in Form umlaufender Kettenförderer mit Greifern, übergeben und von diesen der oder den Abstapelvorrichtungen zugeführt. Jeder der Ausförderer kann eine oder mehrere Abstapelvorrichtungen mit Produktkollektionen versorgen. Um die Flexibilität der Druckweiterverarbeitungsanlagen zu erhöhen, können einzelne Abstapelvorrichtungen auch von mehreren Ausförderern, das heisst zum Beispiel von mehreren Zusammentrag-Vorrichtungen, mit Produktkollektionen versorgt werden können.After passing through the collation line, the collated product collections according to preferred embodiments are shrink-wrapped in film, transferred to outfeed conveyors, for example in the form of revolving chain conveyors with grippers, and supplied by these to the stacking device (s). Each of the exhausters may provide one or more stackers with product collections. In order to increase the flexibility of the print finishing systems, individual stacking devices can also be supplied with product collections by a plurality of outfeed conveyors, that is, for example, by a plurality of collating devices.
Ähnlich wie vorgängig anhand der Zusammentrag-Vorrichtung vom Flystream-Typ beschrieben, lässt sich auch der Ausförderer, der der Abstapelvorrichtung die komplettierten Produktkollektionen zufördert, derart betreiben, dass einzelne oder mehrere Produktkollektionen nicht an die Abstapelvorrichtung abgegeben oder in einen nachgeschalteten Überlauf ausgeschieden werden, sondern gehalten und zurück zum Beginn der Ausförderstrecke geführt werden. Gemäss der vorliegenden Erfindung dient sie vorteilhafter Weise wiederum dazu, der mindestens einen nachgeschalteten Abstapelvorrichtung durch das Generieren leerer Produktpositionen genügend Zeit zu geben Spitzenpakete herzustellen. Die übergeordnete Steuerung kennt die entsprechenden Positionen im Ausförderer, die bereits mit nicht abgegebenen, rückgeführten Kollektionen belegt sind und berücksichtigt diese belegten Positionen bereits vorgängig bei den stromaufwärts durchzuführenden Schritten zur Erzeugung der überlagerten Produktsequenz durch das Einfügen entsprechender leerer Taktpositionen, die stromabwärts sicherstellen, dass eine rückgeführte Produktkollektion nicht mit einer neuen auszufördernden Produktkollektion kollidiert.As described above with reference to the flystream-type gathering apparatus, the outfeed conveyor which feeds the stacking apparatus to the completed product collections can also be operated in such a way that individual or several product collections are not delivered to the stacking apparatus or eliminated in a downstream overflow, but instead held and led back to the beginning of the Ausförderstrecke. According to the present invention, it advantageously serves in turn to give the at least one downstream stacking device sufficient time to generate tip packages by generating empty product positions. The higher-level controller knows the corresponding positions in the discharge conveyor, which are already occupied by non-delivered, returned collections and takes these occupied positions already in advance in the steps to be performed upstream to produce the superimposed product sequence by inserting corresponding empty clock positions, the downstream ensure that a returned product collection did not collide with a new product collection to be promoted.
Die Bestimmung einer Abstapelvorrichtung als Abstapelvorrichtung zum Erzeugen von Spitzenpaketen in einer Druckweiterverarbeitungsanlage mit mehreren Abstapelvorrichtungen kann gemäss weiterer vorteilhafter Ausführungsformen dynamisch erfolgen. Das heisst, es muss eine bestimmte Abstapeleinrichtung nicht zwingend über einen gesamten Produktionszyklus - also während dem Abarbeiten eines kompletten Produktionsplans - als Abstapelvorrichtung zum Erzeugen von Spitzenpaketen fungieren. Werden in bestimmten Phasen der Produktion keine Spitzenpakete benötigt, so werden problemlos und ohne irgendwelche Umrüstschritte Normpakete auf dieser Abstapelvorrichtung hergestellt. Analog dazu kann bei hohem Bedarf nach Spitzenpaketen eine Abstapelvorrichtung die vorgängig Normpakete hergestellt hat, jederzeit dynamisch zur Produktion von Spitzenpaketen eingesetzt werden. Eine sequentielle Kombination der Produktion von Spitzen- und Normpaketen auf der selben Vorrichtung ist möglich.The determination of a stacking device as a stacking device for producing tip packages in a print finishing plant with a plurality of stacking devices can be carried out dynamically according to further advantageous embodiments. This means that a certain stacking device does not necessarily have to function as a stacking device for producing tip packages over an entire production cycle-that is, during the execution of a complete production plan. If no top packages are required in certain phases of the production, standard packages are produced on this stacking apparatus without any problems and without any changeover steps. Similarly, in the case of a high demand for top packages, a stacking device which has previously produced standard packages can be used dynamically at any time for the production of top packages. A sequential combination of the production of peak and standard packages on the same device is possible.
Dieses hohe Mass an Flexibilität wird durch die überlagerte Produktsequenz ermöglicht, die stromaufwärts generiert wird und unter Beibehaltung eines vorgegebenen Taktes die Zuweisung von Abstapelvorrichtungs-spezifischen Produktsequenzen durch gezieltes Ausschleusen aus der überlagerten Produktsequenz stromabwärts ermöglicht.This high level of flexibility is made possible by the superimposed product sequence that is generated upstream and, while maintaining a given clock, allows the allocation of stacker-specific product sequences by targeted purging out of the superimposed product sequence downstream.
Wie bereits vorgängig erwähnt, ist vorzugsweise jeder der Ausförderer stromabwärts von den von ihm versorgten Abstapelvorrichtungen mit einem Überlauf ausgestattet, in den überzählige oder aktuell nicht verarbeitbare Produktkollektionen abgegeben werden können.As already mentioned above, preferably each of the discharge conveyors downstream of the stacking devices supplied by it is provided with an overflow into which excess or currently unworkable product collections can be dispensed.
Je nach Anwendung und Dicke der Produkte sind mehrere Zufördereinrichtungen in einer Zusammentrag-Vorrichtung mit dem gleichen Produkt belegt (Splitbetrieb). Dies hat sich beispielsweise bei dicken Produkten bewährt, von denen jeweils nur eine kleine Anzahl im Magazinschacht einer Zufördereinrichtungen Platz findet und das manuelle Nachfüllen zu langsam von Statten geht um bei hohen Verarbeitungsgeschwindigkeiten die unterbruchsfreie Zuführung von Produkten in die Aufnahmen der Zusammentrag-Vorrichtung durch eine einzige Zufördereinrichtung zu gewährleisten.Depending on the application and thickness of the products, several feeders in a gathering device are occupied with the same product (split operation). This has been proven, for example, in thick products, of which only a small number in the magazine shaft of a Zufördereinrichtungen finds space and manual refilling is too slow from the order at high processing speeds the uninterruptible supply of products in the recordings of the gathering device by a single To ensure feed device.
Gemäss der vorliegenden Erfindung sind die wesentlichen Anlagenteile mit einer übergeordneten computerisierten Steuerung verbunden. Grundsätzlich gilt, dass diese Verbindungen draht- oder leitergebunden oder draht- oder leiterlos ausgebildet sein können. Draht-oder leiterlose Verbindungen können je nach lokaler Situation zum Beispiel mittels Funkverbindung zwischen der Steuerung und den jeweiligen Anlagenteilen hergestellt werden. Es sind vorzugsweise alle wesentlichen Anlagenteile mittelbar oder unmittelbar mit der übergeordneten computerisierten Steuerung verbunden. Für die Durchführung des erfindungsgemässen Verfahrens ist es im einfachsten Fall jedoch ausreichend, dass zu Beginn der Druckweiterverarbeitung die gewünschte überlagerte Produktsequenz gemäss Produktionsplan generiert wird. Die nachfolgenden Verarbeitungsschritte, respektive die daran beteiligten Vorrichtungen und Anlagenteile können in weiteren Ausführungsformen lokal, ohne direkten Kontakt zur übergeordneten Steuerung, gesteuert sein.According to the present invention, the essential parts of the system are connected to a higher-level computerized control. Basically, these connections can be wire or wire connected or wire or conductorless. Depending on the local situation, wire or conductorless connections can be established, for example, by means of a radio link between the controller and the respective system components. It is preferably all essential parts of the system directly or indirectly connected to the higher-level computerized control. However, in the simplest case, it is sufficient for carrying out the method according to the invention that the desired superimposed product sequence according to the production plan is generated at the beginning of the print further processing. The following processing steps, respectively those involved In other embodiments, devices and system components can be controlled locally without direct contact with the higher-level controller.

Stapel S5 ist nochmals zwei Produkte kleiner als Stapel 4, so dass Δ4 wiederum den positiven Wert 2 hat. Um die Abstapeleinrichtung nicht zu überfordern und das Ausschleusen von Kollektionen als Makulatur zu vermeiden, wird vor der Verarbeitung von Stapel S4 die Anlagengeschwindigkeit so weit reduziert, dass der Abstapeleinrichtung genügend Zeit zur Verfügung steht, um den kleineren Stapel 4 herzustellen. Vor der der Verarbeitung von Stapel S5 wird die Anlagengeschwindigkeit nochmals reduziert, so dass der Abstapeleinrichtung genügend Zeit zur Verfügung steht die nun mit herabgesetzter Geschwindigkeit angelieferten Kollektionen zu Stapel 5 zu verarbeiten. Stapel S6 umfasst nur noch drei Produktkollektionen und ist damit 5 Produkte kleiner als S5, so dass Δ5 den Wert 5 annimmt, und den vorgegebenen Schwellenwert T, der strichliniert eingezeichnet ist, übersteigt. Dies bedeutet, dass sich die Veränderung Δ in der Stapelgrösse nicht mehr durch ein weiteres taktsynchrones Herabsetzen der Produktionsgeschwindigkeit innerhalb eines Abstapelzyklus kompensieren lässt, ohne dass die vorgeschalteten Teile der Druckweiterverarbeitungsanlage 1 Gefahr laufen durch das Verzögern den Anlagentakt zu verlieren. Bei Überschreiten des Schwellenwertes T wird die Entlastung der Abstapeleinrichtung 70 nicht mehr allein durch ein weiteres Verlangsamen der vorgeschalteten Anlagenteile 10, 12, 13, 20, 26, 50, 60 und 65 realisiert, sondern es werden Leerpositionen im Produktestrom generiert.Stack S5 is again two products smaller than

Während in den bisher beschriebenen Beispielen der Schwellenwert T jeweils ein vorgegebener Wert der Differenz Δ der Grösse aufeinanderfolgenden Pakete (Sn - Sn+1) war, kann in weiteren vorteilhaften Ausführungen des erfindungsgemässen Verfahrens der Schwellenwert ein vorgegebener Wert einer Differenz Δ' der Mittelwert gebildet aus den Grössen von Gruppen mehrerer aufeinanderfolgender Pakete sein. Vorzugsweise umfassen diese Gruppen zwei bis vier Pakete, besonders bevorzugt 3 Pakete und werden überlappend berechnet. Das heisst der erste Mittelwert wird beispielsweise basierend auf drei aufeinanderfolgenden Paketen 1-3 gebildet. Der nächste Mittelwert wird basierend auf den Grössen der Pakete 2-4 berechnet etc.While in the examples described so far the threshold value T was in each case a predefined value of the difference Δ of the size of successive packets (Sn-Sn + 1), in further advantageous embodiments of the method according to the invention the threshold value can be a predetermined value of a difference Δ ' the sizes of groups of several consecutive packets. Preferably, these groups comprise two to four packets, more preferably 3 packets and are calculated overlapping. That is, the first mean value is based on, for example, three consecutive packets 1-3 formed. The next average is calculated based on the sizes of the packets 2-4, etc.
