Abstract

At a delivery station (1), printed products (4) are unwound from a product reel (6) and transferred to a transfer area (11) of a conveying system (12). The latter has transport members (13) provided with controllable grippers (15) moved by conveying means (19, 19a) or by the force of gravity along a path of transport (14) designed as a closed loop. The printed products (4) are transferred at a delivery area (21) to a further processing device, for example an insetting or collecting drum (28). A buffer section (23), along which the transport members (13) are stored by reducing their mutual distance, is arranged upstream of said dispensing area (21). While an empty winding core (8) is exchanged for a full product reel (6), the supply of printed products (4) to the transfer area (11) is interrupted. During that time, the transport members (13) carrying printed products (4) are taken from the buffer section (23), ensuring a continuous supply of printed products (4) to the delivery station (21).

Description

Vorrichtung zum Zubringen von Druckereierzeugnissen zu einer .AbgabestelleDevice for supplying printed matter to a delivery point
Die vorliegende Erfindung betrifft eine Vorrichtung zum Zubringen von Druckereierzeugnissen, wie Zeitungen, Zeitschriften, Broschüren und dergleichen sowie Beilagen zu solchen Druckereierzeugnissen, zu einer Abgabestelle gemäss Oberbegriff des Anspruches 1.The present invention relates to a device for supplying printed products, such as newspapers, magazines, brochures and the like, as well as supplements to such printed products, to a delivery point according to the preamble of claim 1.
Aus der DE-A-31 23 888 (und der entsprechenden US-A- 4,438,618) ist eine Vorrichtung dieser Art bekannt, bei der die Quelle für die Druckereierzeugnisse ein in einer Abwickelstelle angeordneter Produktewickel ist. In diesem Wickel ist auf einem Wickelkern eine bestimmte Anzahl von Druckereierzeugnissen gespeichert, die durch Abwickeln vom Wickel diesem entnommen und weggeführt werden. Sobald alle Druckereierzeugnisse vom Wickel abgewickelt sind, muss der leere Wickelkern aus der Abwickelstelle entfernt und durch einen neuen, vollen Wickel ersetzt werden. Beim Austauschen eines leeren Wickelkerns durch einen neuen Wickel erleidet die Wegfuhr von Druckereierzeugnissen einen Unterbruch. Dieser Nachteil kann zwar durch Verdoppelung der Abwickelstellen, von denen jeweils die eine in Betrieb steht, währenddem die andere Abwickelstelle mit einem neuen Wickel beschickt wird, behoben werden. Doch ist bei einer solchen Lösung ein erheblicher maschineller Aufwand erforderlich.From DE-A-31 23 888 (and the corresponding US-A-4,438,618) a device of this type is known in which the source for the printed products is a product roll arranged in an unwinding point. In this winding, a certain number of printed products are stored on a winding core, which are taken from the winding and unwound by unwinding it. As soon as all printed products have been unwound from the reel, the empty reel core must be removed from the unwinding point and replaced with a new, full reel. When an empty winding core is replaced by a new winding, the removal of printed products is interrupted. This disadvantage can be remedied by doubling the unwinding points, one of which is in operation while the other unwinding point is being loaded with a new reel. However, such a solution requires considerable mechanical effort.
Der vorliegenden Erfindung liegt nun die Aufgabe zugrunde, eine Vorrichtung der eingangs genannten Art zu schaffen, mit der es möglich ist, trotz der beschränkten Lieferkapazität der Quelle einer nachgeschalteten Abgabestelle kontinuierlich Druckerzeugnisse zuführen zu könne .The present invention has for its object to provide a device of the type mentioned, with which it is possible, despite the limited supply capacity of the source downstream Delivery point to be able to continuously supply printed products.
Diese Aufgabe wird erfindungsgemäs mit einer Vorrichtung mit den Merkmalen des Anspruches 1 gelöst.This object is achieved according to the invention with a device having the features of claim 1.
Im Pufferabschnitt der die Druckereierzeugnisse von der Quelle zur Abgabestelle fördernden Förderanordnung werden die diese Druckereierzeugnisse transportierenden Transportorgane vorübergehend gespeichert. Letztere werden dann aus dieser Pufferstrecke der Abgabestelle zugeführt. Nachdem die Quelle erschöpft ist und entweder gegen eine neuen Quelle ausgetauscht oder wieder mit neuen Druckereierzeugnissen aufgefüllt wird, kann während dieser Zeit die kontinuierliche Zufuhr von Druckereierzeugnissen zur Abgabestelle aus der Pufferstrecke heraus weitergeführt werden, wobei dann die Pufferstrecke in ihrer Länge abgebaut wird, weil ja während dem Auswechseln bzw. Nachfüllen der Quelle keine neuen, mit Druckereierzeugnissen beladene Transportorgane mehr zur Pufferstrecke gelangen.The transport members transporting these printed products are temporarily stored in the buffer section of the conveyor arrangement which conveys the printed products from the source to the delivery point. The latter are then fed from this buffer section to the delivery point. After the source is exhausted and either replaced with a new source or refilled with new printed products, the continuous supply of printed products to the delivery point can be continued from the buffer line during this time, the length of the buffer line then being reduced, because yes during the replacement or refilling of the source, no new transport organs loaded with printed products can reach the buffer line.
Bevorzugte Weiterausgestaltungen der erfindungsgemässen Vorrichtung bilden Gegenstand der abhängigen Ansprüche.Preferred further developments of the device according to the invention form the subject of the dependent claims.
Im folgenden wird anhand der Zeichnung ein Ausführungsbeispiel des Erfindungsgegenstandes näher erläutert. Es zeigt rein schematisch:An exemplary embodiment of the subject matter of the invention is explained in more detail below with reference to the drawing. It shows purely schematically:
Fig. 1 eine Vorrichtung zum Zubringen von Druckereierzeugnissen von einem Produktewickel zu einer Abgabestelle im Zeitpunkt des Austauschens eines Produktewickels, und Fig. 2 die Vorrichtung gemäss Fig. 1 kurz nach der Inbetriebnahme eines vollen Produktewickels.1 shows a device for feeding printed products from a product roll to a delivery point at the time of exchanging a product roll, and 2 shows the device according to FIG. 1 shortly after the start-up of a full product roll.
Die in den Figuren 1 und 2 gezeigte Vorrichtung weist eine Lieferstation 1 sowie eine Verarbeitungsstation 2 auf, die über eine Förderanordnung 3 miteinander verbunden sind. Diese Förderanordnung 3' transportiert auf noch näher zu beschreibende Weise Druckereierzeugnisse 4, nämlich Zeitungen, Zeitschriften, Broschüren und dergleichen, sowie Beilagen zu solchen Druckereierzeugnissen, die von einer sich in der Lieferstation 1 befindlichen Quelle Z geliefert werden. Beim vorliegenden Ausführungsbeispiel dient als Quelle Z eine auswechselbare Speichereinheit 5 bzw. 5', die aus einem Produktewickel 6, der in einem Gestell 7 gelagert ist, das mittels eines geeigneten Transportgerätes verfahren werden kann, gebildet wird. Der Produktewickel 6 besteht aus in bekannter Weise in einer Schuppenformation auf einen Wickelkern 8 aufgewickelten Druckereierzeugnissen. Der Wickelkern 8 ist drehbar im Gestell 7 gelagert.The device shown in FIGS. 1 and 2 has a delivery station 1 and a processing station 2, which are connected to one another via a conveyor arrangement 3. This conveyor arrangement 3 ' transports printed products 4, namely newspapers, magazines, brochures and the like, as well as supplements to such printed products, which are supplied by a source Z located in the delivery station 1, in a manner to be described in more detail below. In the present exemplary embodiment, the source Z is an exchangeable storage unit 5 or 5 ′, which is formed from a product roll 6, which is stored in a frame 7, which can be moved by means of a suitable transport device. The product roll 6 consists in a known manner in a scale formation on a winding core 8 wound printed products. The winding core 8 is rotatably mounted in the frame 7.
In der Fig. 1 ist der Zustand im Zeitpunkt des Austauschens einer leeren Speichereinheit 5' gegen eine solche mit einem vollen Wickel 6 gezeigt, während in der Fig. 2 der Zustand kurz nach Inbetriebnahme einer neuen Speichereinheit 5 mit einem vollen Wickel 6 dargestellt ist.1 shows the state at the time when an empty storage unit 5 'is replaced by one with a full winding 6, while FIG. 2 shows the state shortly after a new storage unit 5 is started up with a full winding 6.
Die vom Wickel 6 abgewickelten Druckereierzeugnisse 4 werden in einer Schuppenformation S von einem Förderer 9, vorzugsweise einem Bandförderer, übernommen und in Richtung des Pfeiles A durch eine Vergleichmässigungseinrichtung 10 hindurch zu einer Uebergabestelle 11 gefördert. Die Vergleichmässigungseinrichtung 10 sorgt auf an sich bekannte Weise dafür, dass der Abstand zwischen aufeinanderfolgenden Druckereierzeugnissen 4 in der Schuppenformation S immer etwa gleich ist und keine Lücken in der Schuppenformation vorhanden sind. An der Uebergabestelle 11 werden die Druckereierzeugnisse 4 einer allgemein mit 12 bezeichneten Förderanlage übergeben.The printed products 4 unwound from the roll 6 are taken over in a scale formation S by a conveyor 9, preferably a belt conveyor, and in the direction of arrow A by a Uniformization device 10 conveyed through to a transfer point 11. The equalization device 10 ensures, in a manner known per se, that the distance between successive printed products 4 in the scale formation S is always approximately the same and that there are no gaps in the scale formation. At the transfer point 11, the printed products 4 are transferred to a conveyor system, generally designated 12.
Die Förderanlage 12 weist eine Anzahl von einzelnen, voneinander unabhängigen Transportorganen 13 auf, die entlang einer als geschlossene Schleife ausgebildeten Förderstrecke 14 in Richtung des Pfeiles B bewegt werden. Die Transportorgane 13 sind voneinander getrennt, d.h. nicht miteinander gekoppelt und voneinander unabhängig. Der Abstand zwischen den Transportorganen 13 kann sich somit ändern. Die Transportorgane 13 weisen steuerbare Greifer 15 auf, die an Wagen oder Schlitten 16 befestigt sind. An der Uebergabestelle 11 erfasst der Greifer 15 jeweils eines Transportorganes 13 ein Druckereierzeugnis 4 an dessen vorlaufenden Kante. Die Förderstrecke 12 besitzt ansteigende Abschnitte 17, 17a sowie abfallende Abschnitte 18, 18a, 18b und 18c, die miteinander abwechseln. Die Bewegung der Transportorgane 13 erfolgt entlang der abfallenden Abschnitte 18-18c unter der Wirkung der Schwerkraft. Gegebenenfalls können auch geeignete Fördermittel vorgesehen werden. Um die Transportorgane 13 entlang der ansteigenden Abschnitte 17 und 17a zu bewegen, sind Fördermittel 19 vorhanden, bzw. können entsprechende Fördermittel 19a vorhanden sein, die in den Figuren 1 und 2 nicht näher dargestellt sind. Zum Ueberführen der Transportorgane 13 von einem abfallenden Abschnitt 18 bzw. 18c in einen ansteigenden Abschnitt 17a bzw. 17 sind Umlenkräder 20a bzw. 20 vorgesehen, die ebenfalls eine Förderwirkung haben. Bei kurzen ansteigenden Abschnitten kann diese Förderwirkung ausreichend sein.The conveyor system 12 has a number of individual, mutually independent transport members 13, which are moved in the direction of arrow B along a conveyor path 14 designed as a closed loop. The transport members 13 are separate from one another, ie are not coupled to one another and are independent of one another. The distance between the transport members 13 can thus change. The transport members 13 have controllable grippers 15 which are fastened to carriages or sleds 16. At the transfer point 11, the gripper 15 of each transport member 13 grips a printed product 4 on its leading edge. The conveyor section 12 has rising sections 17, 17a and falling sections 18, 18a, 18b and 18c, which alternate with one another. The movement of the transport members 13 takes place along the sloping sections 18-18c under the action of gravity. If necessary, suitable funding can also be provided. In order to move the transport members 13 along the rising sections 17 and 17a, conveying means 19 are present, or corresponding conveying means 19a may be present, which are not shown in more detail in FIGS. 1 and 2. To transfer the transport members 13 from a sloping section 18 or 18c in a rising section 17a and 17, deflection wheels 20a and 20 are provided, which also have a conveying effect. This promotional effect may be sufficient for short, rising sections.
Der Verarbeitungsstation 2 ist eine Abgabestelle 21 zugeordnet, an der die Druckereierzeugnisse 4 von den Greifern 15 der Transportorgane 13 freigegeben werden. Vor dieser Abgabestelle 21 ist eine nur schematisch dargestellte Eintakteinrichtung 22 angeordnet, die dafür sorgt, dass die Transportorgane 13 in einer bestimmten Taktfolge zur Abgabestelle 21 gelangen, um eine einwandfreie Uebergabe der Druckereierzeugnisse 4 an die Einrichtungen der Verarbeitungsstation 2 sicherzustellen. Der der Eintakteinrichtung 22 vorgelagerte Abschnitt der Förderstrecke 12 ist als Pufferabschnitt 23 ausgebildet, entlang welchem die Transportorgane 13 gespeichert werden, bevor sie mittels der Eintakteinrichtung 22 abgerufen werden. In diesem Pufferabschnitt 23 nehmen die Transportorgane 13 ihren kleinstmöglichsten gegenseitigen Abstand ein.The processing station 2 is assigned a delivery point 21 at which the printed products 4 are released by the grippers 15 of the transport members 13. In front of this delivery point 21 there is arranged a single-stroke device 22, which is only shown schematically, and which ensures that the transport members 13 arrive at the delivery point 21 in a certain cycle sequence, in order to ensure that the printed products 4 are transferred to the devices of the processing station 2 without any problems. The section of the conveyor line 12 upstream of the infeed device 22 is designed as a buffer section 23, along which the transport members 13 are stored before they are called up by means of the infeed device 22. In this buffer section 23, the transport members 13 take the smallest possible mutual distance.
Die den Umlenkrädern 20, 22a vorgelagerten Abschnitte 18c bzw. 18 der Förderstrecke 12 dienen als Stau- oder Speicherabschnitte 24, 24a, in denen die Transportorgane 13 ebenfalls gepuffert bzw. gespeichert werden können. Dadurch, dass die leeren Transportorgane 13' im Stau- oder Speicherabschnitt 24a gespeichert werden, wird sichergestellt, dass für jedes zur Uebergabestelle 11 gelangende Druckereierzeugnis 4 ein Transportorgan 13' zur Verfügung steht. Dem Pufferabschnitt 23 vorgelagert ist im abfallenden Abschnitt 18a eine Abzweigstelle 25 mit einer nicht näher dargestellten Weiche angeordnet. Von dieser Abzweigstelle 25 führt eine Zweigförderstrecke 26 zu einer Einführstelle 27, die ebenfalls eine nicht dargestellte Weiche aufweist und die stromabwärts der Abgabestelle 21 angeordnet ist. An der Abzweigstelle 25 können leere Transportorgane 13' , d.h. also solche, die keine Druckereierzeugnisse 4 transportieren, aus der Förderstrecke 12 ausgeschleust werden. Die ausgeschleusten leeren Transportorgane 13' werden entlang der Zweigförderstrecke 26 zur Einführstelle 27 bewegt, an der sie mittels der Weiche wieder in die Förderstrecke 14 eingeschleust werden können. D.h., die an der Abzweigstelle 25 ausgeschleusten leeren Transportorgane 13' werden an der Einführstelle 27 wieder mit den leeren Transportorganen 13' vereint, welche an der Abgabestelle 21 die von ihnen geförderten Druckereierzeugnisse 4 abgegeben haben. Zum Umschalten der Weichen der Abzweigstelle 25 und der Einführstelle 27 kann es erforderlich sein, das Zulaufen von Transportorgangen 13, 13' zur Abzweigstelle 25 und zur Einführstelle 27 durch geeignete, nicht näher dargestellte Rückhaltemittel vorübergehend zu unterbrechen.The sections 18c and 18 of the conveyor section 12 upstream of the deflection wheels 20, 22a serve as accumulation or storage sections 24, 24a, in which the transport members 13 can also be buffered or stored. The fact that the empty transport members 13 'are stored in the storage or storage section 24a ensures that a transport member 13' is available for each printed product 4 arriving at the transfer point 11. In front of the buffer section 23, a branching point 25 with a switch, not shown, is arranged in the falling section 18a. A branch conveyor section 26 leads from this branch point 25 to an insertion point 27, which likewise has a switch, not shown, and which is arranged downstream of the discharge point 21. At the branch point 25, empty transport members 13 ', ie those which do not transport printed products 4, can be discharged from the conveyor line 12. The discharged empty transport members 13 'are moved along the branch conveyor line 26 to the insertion point 27, at which they can be re-introduced into the conveyor line 14 by means of the switch. That is to say, the empty transport members 13 'discharged at the branch point 25 are reunited at the insertion point 27 with the empty transport members 13' which have delivered the printed products 4 they have conveyed to the delivery point 21. To switch the points of the branch point 25 and the insertion point 27, it may be necessary to temporarily interrupt the inflow of transport oranges 13, 13 'to the branch point 25 and the insertion point 27 by means of suitable retaining means, not shown in detail.
In der Verarbeitungsstation 2 befindet sich eine nur schematisch dargestellte Einstecktrommel 28, die von bekannter Bauart ist und die im Gegenuhrzeigersinn drehend angetrieben ist. Die Einstecktrommel 28 besitzt radial verlaufende Aufnahmeabteile 29, in die die an der Abgabestelle 21 freigegebenen Druckereierzeugnisse 4 fallen. Die von den Transportorganen 13 transportierten Druckereierzeugnisse 4 sind im vorliegenden Fall gefaltete Druckbogen, die von den Greifern 15 der Transportorgane 13 an ihrer der Falzkante gegenüberliegenden, offenen Seitenkante gehalten werden. Es versteht sich, dass es auch möglich ist, in der Einstecktrommel 28 die Druckereierzeugnisse 4 statt einzustecken zusammenzutragen .In the processing station 2 there is a plug-in drum 28, only shown schematically, which is of a known type and which is driven to rotate in the counterclockwise direction. The insertion drum 28 has radially extending receiving compartments 29, into which the printed products 4 released at the delivery point 21 fall. The printed products 4 transported by the transport members 13 are folded printed sheets in the present case, and those by the grippers 15 of the transport members 13 are held at their open side edge opposite the folded edge. It goes without saying that it is also possible to collect the printed products 4 in the insertion drum 28 instead of inserting them.
Selbstverständlich können an der Verarbeitungsstation 2 auch andere Einrichtungen zur Weiterverarbeitung der zugeführten Druckereierzeugnisse 4 angeordnet sein, z.B. andere Einsteck- und Zusammentrageinrichtungen als Verarbeitungstrommeln oder aber Sammeleinrichtungen zum Sammeln der Druckbogen 4, wie Sammeltrommeln oder Sammelstrecken. Weiter ist es auch denkbar, in der Verarbeitungsstation 2 die Druckereierzeugnisse 4 zu Paketen zu stapeln.Of course, other devices for further processing of the supplied printed products 4 can also be arranged at the processing station 2, e.g. inserting and collating devices other than processing drums or collecting devices for collecting the printed sheets 4, such as collecting drums or collecting sections. Furthermore, it is also conceivable to stack the printed products 4 into packages in the processing station 2.
Wie aus der vorangehenden Beschreibung hervorgeht, werden die durch Fördermittel oder unter Einwirkung der Schwerkraft in Richtung des Pfeiles B von der Uebergabestelle 11 zur Abgabestelle 21 bewegten, beladenen Transportorgane 13 entlang des Pufferabschnittes 23, aber auch entlang des Stau- oder Speicherabschnittes 24, unter Verkleinerung des gegenseitigen Abstandes vorübergehend gepuffert. Diese Pufferung der Transportorgane 13 erlaubt es, auch bei einem Unterbruch der Zufuhr von Druckereierzeugnissen 4 zur Uebergabestelle 11 der Abgabestelle 21 weiterhin kontinuierlich Druckereierzeugnisse 4 zuzuführen, und zwar in erster Linie aus dem Pufferabschnitt 23. Dabei nimmt die Länge dieses Pufferabschnittes 23 vorübergehend ab. Der Grund für einen Unterbruch der Zulieferung von Druckereierzeugnissen 4 zur Uebergabestelle 11 liegt darin, dass die Quelle Z eine beschränkte Lieferkapazität hat, d.h. im Produktewickel 6 nur eine beschränkte Anzahl von Druckereierzeugnissen 4 gespeichert ist.As can be seen from the preceding description, the loaded transport members 13 moved by conveying means or under the influence of gravity in the direction of arrow B from the transfer point 11 to the discharge point 21 along the buffer section 23, but also along the stowage or storage section 24, with reduction of the mutual distance temporarily buffered. This buffering of the transport members 13 makes it possible to continue to supply printed products 4 continuously, especially from the buffer section 23, even if the supply of printed products 4 to the transfer point 11 is interrupted, primarily from the buffer section 23. The length of this buffer section 23 temporarily decreases. The reason for an interruption in the delivery of printed products 4 to the transfer point 11 is that the source Z has a limited delivery capacity has, that is, only a limited number of printed products 4 is stored in the product roll 6.
In der Fig. 1 ist gezeigt, dass die Speichereinheit 5' entladen ist, d.h. dass der Wickelkern 8 leer ist. Das letzte noch vom Wickelkern 8 abgewickelte Druckereierzeugnis ist mit 4' bezeichnet. Jetzt uss die leere Speichereinheit 5' gegen eine neue Speichereinheit 5 mit einem vollen Produktewickel 6 ausgetauscht werden, wie das in Fig. 1 angedeutet ist. Währenddessen läuft die Förderanlage 12 weiter, damit der Abgabestelle 21 weiterhin Druckereierzeugnisse 4 zugeführt werden.In Fig. 1 it is shown that the storage unit 5 'is discharged, i.e. that the winding core 8 is empty. The last printed product still unwound from the winding core 8 is designated by 4 '. Now the empty storage unit 5 'has to be exchanged for a new storage unit 5 with a full product roll 6, as indicated in FIG. 1. In the meantime, the conveyor system 12 continues to run so that the delivery point 21 continues to be supplied with printed products 4.
Sobald die neue Speichereinheit 5 lieferbereit ist, werden vom neuen Produktewickel 6 die Druckereierzeugnisse 4 in Schuppenformation abgewickelt und der Uebergabestelle 11 zugeführt, wie das aus Fig. 2 ersichtlich ist. Das erste vom neuen Produktewickel 6 abgewickelte Druckereierzeugnis ist in der Fig. 2 mit 4'' bezeichnet. Zwischen diesem Druckereierzeugnis 4'' und dem letzten vom vorangehenden Produktewickel abgewickelten Druckereierzeugnis 4' bildet sich eine Lücke, wie das Fig. 2 erkennen lässt. Während des Lieferunterbruches von Druckereierzeugnissen 4 zur Uebergabestelle 11 wird wie bereits erwähnt der Pufferabschnitt 23 abgebaut, d.h. dessen Länge nimmt ab. Sobald jedoch die Produktequelle Z wieder Druckereierzeugnisse 4 liefert, wird die Pufferstrecke 23 wieder aufgefüllt, da die Liefergeschwindigkeit der Quelle Z grösser ist als die Zuführgeschwindigkeit von Transportorganen 13 zur Abgabestelle 21. In den jeweils in die Lieferstation 1 eingebrachten neuen Produktewickeln 6 können dieselben Druckereierzeugnisse gespeichert sein wie im vorangehend abgewickelten Produktewickel oder aber auch andersartige Druckereierzeugnisse .As soon as the new storage unit 5 is ready for delivery, the printed products 4 are unwound from the new product roll 6 in a scale formation and fed to the transfer point 11, as can be seen in FIG. 2. The first printed product unwound from the new product roll 6 is designated 4 ″ in FIG. 2. A gap is formed between this printed product 4 ″ and the last printed product 4 ′ unwound from the previous product roll, as can be seen in FIG. 2. As already mentioned, the buffer section 23 is reduced during the interruption of delivery of printed products 4 to the transfer point 11, ie its length decreases. However, as soon as the product source Z again supplies printed products 4, the buffer zone 23 is refilled, since the delivery speed of the source Z is greater than the feed speed of transport elements 13 to the delivery point 21. The same printed products can be stored in the new product rolls 6 introduced into the delivery station 1 as in the previously processed product roll, or else different types of printed products.
Anstelle der Speichereinheiten 5, 5' mit Produktewickeln 6 können auch andere Quellen Z von beschränkter Lieferkapazität verwendet werden, z.B. Stapel, die nach beendetem Abbau wieder nachgefüllt werden müssen.Instead of the storage units 5, 5 'with product windings 6, other sources Z of limited delivery capacity can also be used, e.g. Stacks that need to be refilled after dismantling.
Die in den Figuren 1 und 2 nur rein schematisch dargestellten Transportorgane 13 können jede geeignete Ausbildung haben. Die Förderstrecke 14 der Förderanlage 12 kann auch so ausgebildet werden, dass die Druckereierzeugnisse 4 entlang der ganzen Strecke hängend transportiert werden.The transport members 13 shown only schematically in Figures 1 and 2 can have any suitable training. The conveyor section 14 of the conveyor system 12 can also be designed such that the printed products 4 are transported hanging along the entire route.
Ueberhaupt kann die Förderanlage 12 jede geeignete andere Ausbildung haben. Wichtig ist nur, dass der Abstand der entlang der Förderstrecke 14 der Förderanlage 12 bewegten Transportorgane 13 verändert werden kann. Anstelle einer Förderanlage 12 mit Transportorganen 13, die wie beschrieben nicht miteinander gekoppelt sind, können auch Förderanlagen verwendet werden, bei denen die Transportorgane so miteinander verbunden sind, dass der Abstand zwischen den Transportorganen in gewissen Grenzen verändert werden kann, wie das z.B. aus der EP-A-0 309 702 (und der entsprechenden US-A-4, 887, 809) und der EP-A-0 633 212 (und der entsprechenden US-A-5, 503, 264) bekannt ist. In general, the conveyor system 12 can have any other suitable training. It is only important that the distance between the transport members 13 moved along the conveyor section 14 of the conveyor system 12 can be changed. Instead of a conveyor system 12 with transport elements 13 which are not coupled to one another as described, conveyor systems can also be used in which the transport elements are connected to one another in such a way that the distance between the transport elements can be changed within certain limits, such as e.g. from EP-A-0 309 702 (and the corresponding US-A-4, 887, 809) and EP-A-0 633 212 (and the corresponding US-A-5, 503, 264).
