Abstract

By means of a first band or belt conveyor an imbricated product stream or formation, formed by product packs, each composed of two overlying printed products, is inputted to a second band or belt conveyor. The conveying velocity of the second band conveyor is twice as large as the conveying velocity of the first band conveyor. Above the second band conveyor there is arranged a retarding or delay device containing an endless transport band. This endless transport band possesses a conveying velocity which is half as large as the conveying velocity of the second band conveyor. The transport band is perforated and travels over a negative pressure chamber operatively connected with a vacuum pump. During movement of a product pack past the negative pressure chamber the uppermost situated product of such pack is seized at its freely exposed region by the transport band and retained thereat by means of the prevailing negative pressure. The seized or engaged printed product is moved by the transport band with a velocity which is half as great as the velocity of movement of the product situated therebelow. In this manner it is possible to pull apart or separate the overlying printed products.

Description

Die vorliegende Erfindung betrifft eine Vorrichtung zum Auseinanderziehen von in einem Schuppenstrom anfallenden flächigen Erzeugnissen, insbesondere Druckprodukten, gemäss Oberbegriff des Anspruches 1.The present invention relates to a device for pulling apart flat products produced in a shingled stream, in particular printed products, according to the preamble of claim 1.

Eine derartige Vorrichtung ist aus der DE-OS 28 22 060 (und der entsprechenden US-PS 4 201 286) bekannt, bei der die Fördereinrichtung durch ein endloses Förderorgan gebildet ist, das in regelmässigen Abständen mit Mitnehmern versehen ist. Die Mitnehmer, deren Abstand grösser ist als der gegenseitige Abstand der Erzeugnisse im ankommenden Schuppenstrom (Schuppenabstand), greifen an den nachlaufenden Kanten der Erzeugnisse an. Die Mitnehmer ziehen nun die Erzeugnisse innerhalb der Schuppenformation auseinander und bewirken dabei eine Vergleichmässigung des Schuppenabstandes. Das Auseinanderziehen der Erzeugnisse erfolgt bei dieser Vorrichtung nur um das zur Erzielung dieser Vergleichmässigung erforderliche Mass. Die Vorrichtung ist daher nicht dazu vorgesehen, den Abstand zwischen den Erzeugnissen um einen erheblichen Betrag zu vergössern, d. h. beispielsweise zu verdoppeln. Zur Sicherstellung eines einwandfreien Erfassens jedes ankommenden Erzeugnisses durch einen Mitnehmer muss zwischen dem Zuförderer und dem Förderorgan eine Synchronisation bestehen, was einen entsprechenden apparativen Aufwand bedingt.Such a device is known from DE-OS 28 22 060 (and the corresponding US-PS 4 201 286), in which the conveying device is formed by an endless conveying member which is provided with drivers at regular intervals. The drivers, the distance between which is greater than the mutual distance of the products in the incoming stream of shingles (scale distance), attack the trailing edges of the products. The drivers now pull the products apart within the shed formation and thereby even out the shed spacing. The pulling apart of the products takes place in this device only by the amount necessary to achieve this uniformity. The device is therefore not intended to increase the distance between the products by a significant amount, i. H. for example, to double. To ensure a flawless detection of each incoming product by a driver, there must be a synchronization between the feeder and the conveyor, which requires a corresponding outlay on equipment.

Wie es aus der EP-OS 0 013 920 bekannt ist, werden Druckprodukte oft in Paketen zu zwei Produkten transportiert. Sind jedoch die Produkte im Anschluss an den Transport einzeln zu verarbeiten, so ist es erforderlich, die in jedem Paket sich überdeckenden Produkte wieder soweit voneinander zu trennen, dass die Produkte einzeln manipuliert werden können. Hiefür ist die vorstehend erwähnte, bekannte Vorrichtung jedoch nicht geeignet.As is known from EP-OS 0 013 920, printed products are often transported in packages of two products. However, if the products are to be processed individually after the transport, it is necessary to separate the products that overlap in each package so far that the products can be manipulated individually. However, the known device mentioned above is not suitable for this.

Der vorliegenden Erfindung liegt nun die Aufgabe zugrunde, eine Vorrichtung der eingangs genannten Art zu schaffen, die mit einfachen Mitteln ein Auseinanderziehen der Erzeugnisse um einen erheblichen Betrag ermöglicht und die es zudem erlaubt, einen ankommenden Schuppenstrom, der durch Pakete von übereinanderliegenden Erzeugnissen gebildet ist, in eine Formation umzuformen, in der die Erzeugnisse einzeln dachziegelartig aufeinander liegen.The present invention is based on the object of providing a device of the type mentioned at the outset which, with simple means, enables the products to be pulled apart by a considerable amount and which also allows an incoming stream of scale to be formed which is formed by packets of products lying one above the other, to transform into a formation in which the products lie one on top of the other like roof tiles.

Diese Aufgabe wird erfindungsgemäss durch die im kennzeichnenden Teil des Anspruches 1 aufgeführten Merkmale gelöst.This object is achieved according to the invention by the features listed in the characterizing part of claim 1.

Dadurch, dass die Verzögerungseinrichtung auf derjenigen Seite der Schuppenformation angeordnet ist, an der die Erzeugnisse im Bereich ihrer vorlaufenden Kante freiliegen, ist ein einwandfreies Einwirken der Verzögerungseinrichtung auf die Erzeugnisse ohne Schwierigkeiten gewährleistet. Im weitem ist es möglich, die Freigabe des von der Verzögerungseinrichtung beeinflussten Erzeugnisses durch ein nachfolgendes Erzeugnis zu bewirken, so dass eine aufwendige Steuerung entfallen kann. Auch ist eine genaue Synchronisation zwischen Zuförderer und Fördereinrichtung nicht zwingend nötig.The fact that the delay device is arranged on the side of the scale formation on which the products are exposed in the region of their leading edge ensures that the delay device works correctly on the products without difficulty. It is also possible to effect the release of the product influenced by the delay device by a subsequent product, so that complex control can be dispensed with. A precise synchronization between the feed conveyor and the conveyor device is also not absolutely necessary.

Da die von der Verzögerungseinrichtung nicht bzw. nicht mehr beeinflussten Erzeugnisse mit einer Geschwindigkeit weggefördert werden, die um ein der Vergrösserung des Schuppenabstand entsprechendes Mass höher ist als die Zuführgeschwindigkeit der Erzeugnisse, kann der anfallende, vom Zuförderer zugeführte Schuppenstrom ohne Staubildung verarbeitet werden.Since the products which are not or no longer influenced by the delay device are conveyed away at a speed which is higher by an amount corresponding to the enlargement of the scale distance than the feed speed of the products, the resulting stream of shingles supplied by the feed conveyor can be processed without jamming.

Es ist von Vorteil, wenn bei der bevorzugten Ausführungsform gemäss Anspruch 2 das Transportband zum Beispiel durch eine Lochung luftdurchlässig gemacht und über eine Unterdruckkammer geführt wird. Bei einer solchen Lösung dienen die auf die Unterdruckkammer zulaufenden Erzeugnisse als Schieber, der die Unterdruckkammer kurzzeitig verschliesst und so die Freigabe des vorgängig durch die Verzögerungseinrichtung erfassten Erzeugnisses ermöglicht.It is advantageous if, in the preferred embodiment according to claim 2, the conveyor belt is made air-permeable, for example through a perforation, and is guided over a vacuum chamber. In such a solution, the products running towards the vacuum chamber serve as a slide which briefly closes the vacuum chamber and thus enables the product previously detected by the delay device to be released.

Die erfindungsgemässe Vorrichtung eignet sich insbesondere, jedoch nicht ausschliesslich, dazu, eine Formation, die durch schuppenförmig aufeinander liegende Pakete gebildet ist, die je aus wenigstens zwei sich vollständig überdeckenden Erzeugnissen bestehen, in einen Schuppenstrom umzuwandeln, in dem sich die Erzeugnisse einzeln gegenseitig dachziegelartig überlappen.The device according to the invention is particularly, but not exclusively, suitable for converting a formation which is formed by packages lying one above the other in the form of scales, each consisting of at least two completely overlapping products, into a stream of shingles in which the products individually overlap one another like roof tiles .

Im folgenden wird anhand der Zeichnung ein Ausführungsbeispiel des Erfindungsgegenstandes näher erläutert. Es zeigen in Seitenansicht und rein schematisch :

  • Figur 1 eine Vorrichtung zum Auseinanderziehen von Druckprodukten, die in schuppenartig übereinander liegenden Paketen, die je aus zwei sich vollständig überdeckenden Druckprodukten gebildet sind, anfallen,
  • Figur 2 bis 4 die Vorrichtung gemäss Fig. 1 in aufeinanderfolgenden Zeitpunkten ihres Betriebes, und
  • Figuren 5 und 6 die Vergrösserung des Abstandes zwischen den Produkten innerhalb einer Schuppenformation mittels der Vorrichtung gemäss Fig. 1.
An exemplary embodiment of the subject matter of the invention is explained in more detail below with reference to the drawing. In a side view and purely schematically:
  • FIG. 1 shows a device for pulling apart printed products which are produced in packages lying one above the other in the manner of scales, each of which is formed from two completely overlapping printed products,
  • 2 to 4 the device according to FIG. 1 at successive times of its operation, and
  • 5 and 6 the enlargement of the distance between the products within a scale formation by means of the device according to FIG. 1.

Wie die Fig. 1 zeigt, ist einem als Bandförderer ausgebildeten Zuförderer 1 eine Fördereinrichtung 2 nachgeschaltet, die ebenfalls als Bandförderer ausgebildet ist. Der Bandförderer 1 wird auf nicht näher dargestellte Weise in Richtung des Pfeiles X mit einer Geschwindigkeit V1 angetrieben. Der andere Bandförderer 2 wird auf ebenfalls nicht näher dargestellte Weise in derselben, durch den Pfeil Y angezeigten Richtung angetrieben, und zwar mit einer Geschwindigkeit V2, die doppelt so gross ist wie die Fördergeschwindigkeit V1 des Bandförderers 1.As shown in FIG. 1, a feed device 2, which is designed as a belt conveyor, is followed by a conveyor device 2, which is also designed as a belt conveyor. The belt conveyor 1 is driven in a direction not shown in the direction of arrow X at a speed V1 . The other belt conveyor 2 is driven in a manner also not shown in the same direction indicated by the arrow Y, at a speed V2 that is twice as high as the conveyor speed V1 of the belt conveyor 1.

Durch den Bandförderer 1 wird der Fördereinrichtung 2 ein Schuppenstrom S zugeführt, der durch dachziegelartig übereinander liegende Pakete 3 gebildet wird. Jedes Paket 3 wird durch zwei sich im wesentlichen vollständig überdeckende Druckprodukte 3 und 4 gebildet, deren vorlaufende Kante 4a bzw. 5a frei liegt. Der Abstand der Pakete 3 innerhalb der Schuppenformation S ist mit A bezeichnet.The conveyor is 1 by the conveyor device 2 is supplied with a shingled stream S which is formed by packages 3 lying one above the other in the manner of roof tiles. Each package 3 is formed by two essentially completely overlapping printed products 3 and 4, the leading edge 4a and 5a of which is exposed. The spacing of the packets 3 within the scale formation S is denoted by A.

Oberhalb der Fördereinrichtung 2 ist eine Verzögerungseinrichtung 6 angeordnet, die ein endloses, gelochtes oder sonstwie luftdurchlässig ausgebildetes Transportband 7 aufweist. Dieses Transportband 7 ist über Führungsrollen 8 und 9 sowie um eine Spannrolle 10 herumgeführt. Die Führungsrollen 8 und 9 sind mittels einer Welle 11 bzw. 12 in einer Wippe 13 gelagert, die um die Welle 11 schwenkbar ist. Auf der Welle 12 ist weiter ein Paar von Abstützrollen 14 angeordnet, von dem nur die eine Rolle dargestellt ist. Das Transportband 7 wird auf nicht näher dargestellte Weise in Richtung des Pfeiles Z, d. h. mit demselben Fördersinn wie der Bandförderer 2, angetrieben. Die Antriebsgeschwindigkeit des Transportbandes 7 beträgt v1, und ist demzufolge gleich der Fördergeschwindigkeit des Zuförderers 1 und nur halb so gross wie die Fördergeschwindigkeit V2 des Bandförderers 2.A delay device 6 is arranged above the conveyor device 2 and has an endless, perforated or otherwise air-permeable conveyor belt 7. This conveyor belt 7 is guided over guide rollers 8 and 9 and around a tension roller 10. The guide rollers 8 and 9 are mounted by means of a shaft 11 or 12 in a rocker 13 which is pivotable about the shaft 11. On the shaft 12 a pair of support rollers 14 is further arranged, of which only one roller is shown. The conveyor belt 7 is driven in a manner not shown in the direction of arrow Z, ie with the same direction of conveyance as the belt conveyor 2. The drive speed of the conveyor belt 7 is v 1 , and is therefore equal to the conveying speed of the feed conveyor 1 and only half as large as the conveying speed V2 of the belt conveyor 2.

Unmittelbar benachbart zur Bewegungsbahn des Schuppenstromes S und oberhalb desselben ist eine Unterdruckkammer 15 angeordnet, über die das Transportband 7 läuft und die mit einer nur schematisch dargestellten Vakuumpumpe 16 in Verbindung steht.Immediately adjacent to the movement path of the scale stream S and above it is a vacuum chamber 15, through which the conveyor belt 7 runs and which is connected to a vacuum pump 16, which is only shown schematically.

Anhand der Fig. 2 bis 4 wird nun die Wirkungsweise der Vorrichtung gemäss Fig. 1 erläutert.The mode of operation of the device according to FIG. 1 will now be explained with reference to FIGS. 2 to 4.

In dem in Fig. 2 gezeigten Zeitpunkt steht das mit 4" bezeichnete Produkt eines Paketes mit dem Transportband 7 in Berührung. Durch den in der Unterdruckkammer 15 herrschenden und durch das gelochte Transportband 7 wirkenden Unterdruck wird dieses Druckprodukt 4" am Transportband 7 gehalten und zudem vom darunter liegenden Druckprodukt 5" etwas abgehoben. Das vom Transportband 7 erfasste Produkt 4" wird durch dieses mit der Geschwindigkeit V1 bewegt, während das darunter liegende Druckprodukt 5" mit der Geschwindigkeit V2 in Richtung des Pfeiles Y bewegt wird. Das unten liegende Produkt 5" wird somit unter dem aufliegenden Produkt 4" hervorgezogen.At the point in time shown in FIG. 2, the product of a package designated 4 "is in contact with the conveyor belt 7. Due to the negative pressure prevailing in the vacuum chamber 15 and acting through the perforated conveyor belt 7, this print product 4" is held on the conveyor belt 7 and also slightly lifted from the print product 5 "underneath. The product 4" gripped by the conveyor belt 7 is moved by it at the speed V1 , while the print product 5 "underneath is moved at the speed V2 in the direction of the arrow Y. The product 5 below "is thus extracted from the overlying product 4".

Das Produkt 4" wird solange durch das Transportband 7 bewegt, bis die mit 4' und 5' bezeichneten Produkte des nächsten Paketes 3' in den Wirkbereich des Transportbandes 7 und der Unterdruckkammer 15 gelangen, wie das in Fig. 3 dargestellt ist. Dieses Produktepaar 4', 5' wirkt nun in der Art eines Schiebers, der die Unterdruckkammer 15 verschliesst und so eine Freigabe des vorgängig in seiner Bewegung verzögerten Druckproduktes 4" bewirkt, das nun mit der Geschwindigkeit v2 weiterbewegt wird. Nun kommt das obenliegende Produkt 4' des nachfolgenden Produktepaketes 3' mit dem Transportband 7 in Berührung, an dem es, wie bereits erläutert, durch Unterdruck gehalten und zudem etwas vom darunter liegenden Produkt 5' abgehoben wird. Letzteres wird mit der Fördergeschwindigkeit v2 weiterbewegt, während das obere Druckprodukt 4' durch das Transportband 7 mit der Geschwindigkeit v1 mitgenommen wird. Auf diese Weise wird das Produkt 5' unter dem darüber liegenden Produkt 4' hervorgezogen, so dass nun der Bereich B" an seiner vorlaufenden Kante 5a freigelegt wird (Fig. 4). Hinter der Verzögerungseinrichtung 6, d. h. hinter der Unterdruckkammer 15, wird somit ein Schuppenstrom S' gebildet, bei dem auch die Druckprodukte 4 und 5 dachziegelartig übereinander liegen, die im ankommenden Schuppenstrom S innerhalb eines Paketes 3 übereinander lagen. Da die Fördergeschwindigkeit V2 des Bandförderers 2 doppelt so gross ist wie die Zuführgeschwindigkeit v1 des Schuppenstromes S sowie die Fördergeschwindigkeit des Transportbandes 7, ist der Schuppenabstand A' im Schuppenstrom S' etwa gleich wie der Schuppenabstand A im ankommenden Schuppenstrom S. Durch entsprechende Wahl des Verhältnisses zwischen den Geschwindigkeiten V1 und V2 kann das Verhältnis zwischen den Schuppenabständen A und A' im ankommenden und weggeführten Schuppenstrom S bzw. S' verändert werden.The product 4 "is moved through the conveyor belt 7 until the products of the next package 3 ', designated 4' and 5 ', reach the effective area of the conveyor belt 7 and the vacuum chamber 15, as shown in FIG. 3. This pair of products 4 ', 5' now acts in the manner of a slide which closes the vacuum chamber 15 and thus releases the previously delayed printed product 4 "which is now moved further at the speed v 2 . Now the overhead product 4 'of the subsequent product package 3' comes into contact with the conveyor belt 7, on which, as already explained, it is held by negative pressure and is also somewhat lifted off from the underlying product 5 '. The latter is moved on with the conveying speed v 2 , while the upper printed product 4 'is carried along by the conveyor belt 7 at the speed v 1 . In this way, the product 5 'is drawn out from the product 4' lying above it, so that the area B "is now exposed at its leading edge 5a (FIG. 4). Behind the delay device 6, ie behind the vacuum chamber 15, is thus a shingled stream S 'is formed, in which the printed products 4 and 5 also lie on top of one another in the manner of roof tiles, which lay one above the other in the incoming shingled stream S within a package 3. Since the conveying speed V2 of the belt conveyor 2 is twice as great as the feeding speed v 1 of the shingled stream S and the conveying speed of the conveyor belt 7, the scale distance A 'in the scale stream S' is approximately the same as the scale distance A in the incoming scale stream S. By appropriately selecting the ratio between the speeds V1 and V2 , the ratio between the scale distances A and A 'in the incoming and removed scale stream S or S 'are changed.

Die Vorrichtung gemäss Fig. 1 kann noch auf andere als die beschriebene Weise verwendet werden. So lässt sich mit dieser Vorrichtung auch der Schuppenabstand in einer Schuppenformation vergrössern, in welcher jedes Produkt das vorangehende Produkt nur teilweise überlappt. Eine solche Verwendung der Vorrichtung gemäss Fig. 1 wird nun anhand der Fig. 5 und 6 erläutert.The device according to FIG. 1 can also be used in a manner other than that described. With this device, it is also possible to increase the scale spacing in a scale formation in which each product only partially overlaps the preceding product. Such a use of the device according to FIG. 1 will now be explained with reference to FIGS. 5 and 6.

Wird die in Fig. 5 dargestellte Schuppenformation S mit der Geschwindigkeit v1 durch den Zuförderer 1 der Fördereinrichtung 2 zugeführt und von dieser mit der Geschwindigkeit V2 an der Verzögerungseinrichtung 6 vorbeibewegt, so werden auf die anhand der Fig. 2 bis 4 beschriebene Weise alle Druckprodukte 17, 18, 19 und 20 durch das Transportband 7 solange mit der Geschwindigkeit v1 bewegt, bis das nächstfolgende Produkt ein Ablösen des vorgängig am Transportband 7 festgehaltenen Produktes bewirkt. Ist die Geschwindigkeit V2 doppelt so gross wie die Geschwindigkeit V1, so wird auf diese Weise der Schuppenabstand A2 im weggeführten Schuppenstrom S' (Fig. 6) doppelt so gross wie der Schuppenabstand A1 im ankommenden Schuppenstrom S (Fig. 5). Durch ein solches Auseinanderziehen der Druckprodukte 17, 18, 19 und 20 ist es möglich, einen Schuppenstrom S mit unregelmässigen Schuppenabständen zu vergleichmässigen. Dies wird im folgenden nun erläutert.If the scale formation S shown in FIG. 5 is fed at a speed v 1 by the feed conveyor 1 to the conveyor device 2 and is moved past the delay device 6 at a speed V2 , then all of the printed products become in the manner described with reference to FIGS 17, 18, 19 and 20 moved by the conveyor belt 7 at a speed v 1 until the next product to come off causes the product previously held on the conveyor belt 7 to detach. If the speed V2 is twice as high as the speed V1 , the scale distance A 2 in the removed scale stream S '(FIG. 6) becomes twice as large as the scale distance A 1 in the incoming scale stream S (FIG. 5). By pulling the printed products 17, 18, 19 and 20 apart in this way, it is possible to even out a scale flow S with irregular scale distances. This will now be explained in the following.

Wie die Fig. 5 zeigt, entsprechen die Abstände zwischen den vorlaufenden Kanten 17a, 18a, 19a und 20a der ankommenden Druckprodukte 17, 18, 19 und 20 nicht dem Sollabstand A1. Bei überall gleichem Schuppenabstand müssten sich in der Darstellung gemäss Fig. 5 die vorlaufenden Kanten 17a, 18a, 19a und 20a in den Positionen befinden, die durch die mit I, II, III und IV bezeichneten Striche dargestellt sind. Wie Fig. 5 zeigt, liegt jedoch die vorlaufende Kante 18a des Druckproduktes 18 um die Strecke a hinter der mit II bezeichneten Sollposition zurück, während die vorlaufende Kante 20a des Druckproduktes 20 um die Strecke b vor der mit IV bezeichneten Sollposition liegt.As shown in FIG. 5, the distances between the leading edges 17a, 18a, 19a and 20a of the incoming print products 17, 18, 19 and 20 do not correspond to the target distance A 1 . 5, the leading edges 17a, 18a, 19a and 20a should be in the positions indicated by I, II, III and IV Neten dashes are shown. As shown in FIG. 5, however, the leading edge 18a of the printed product 18 lies a distance a behind the desired position designated by II, while the leading edge 20a of the printed product 20 lies by the distance b before the desired position designated by IV.

In Fig. 6 ist nun in der Fig. 5 entsprechender Darstellung der Schuppenstrom S' nach dem Vorbeilaufen an der Verzögerungseinrichtung 6 dargestellt. Die Sollpositionen der vorlaufenden Kanten 17a', 18a', 19a' und 20a' sind entsprechend mit I', ll', lll' und IV' bezeichnet. Nach wie vor liegt die vorlaufende Kante 18a' um denselben Betrag a hinter der mit II' bezeichneten Sollposition zurück, während die vorlaufende Kante 20a' um denselben Betrag b vor der mit IV' bezeichneten Sollposition liegt. Nach dem Auseinanderziehen des Schuppenstromes ist somit die Abweichung der Druckprodukte 18' und 20' von ihrer Sollage betragsmässig gleich wie beim ankommenden Schuppenstrom S. Da jedoch der Schuppenabstand A2 vergrössert, d. h. verdoppelt, wurde, hat sich die prozentuale Abweichung der Druckprodukte 18' und 20' von ihrer Sollage entsprechend verringert, d. h. halbiert.In FIG. 6, the scale flow S ′ after the passage past the delay device 6 is shown in a corresponding representation in FIG. 5. The nominal positions of the leading edges 17a ', 18a', 19a 'and 20a' are correspondingly designated I ', ll', III 'and IV'. The leading edge 18a 'is still behind the desired position designated II' by the same amount a, while the leading edge 20a 'lies ahead of the desired position designated IV' by the same amount b. After the shingled stream has been pulled apart, the deviation of the printed products 18 'and 20' from their target position is the same as for the incoming shingled stream S. However, since the shingled distance A 2 has been increased, ie doubled, the percentage deviation of the printed products 18 'and 20 'of their target position reduced accordingly, ie halved.

Die beschriebene Vorrichtung hat nun den Vorteil, dass jedes Produkt selbsttätig für die Ablösung des vorangehenden Produktes vom Transportband 7 sorgt. Eine spezielle Steuerung hiefür ist somit nicht erforderlich.The device described now has the advantage that each product automatically takes care of the detachment of the preceding product from the conveyor belt 7. A special control for this is therefore not necessary.

Es versteht sich, dass die beschriebene Vorrichtung in verschiedenen Teilen auch anders als wie beschrieben ausgebildet werden kann. Von den verschiedenen, möglichen Varianten wird im folgenden nur auf einige wenige hingewiesen.It goes without saying that the described device can also be designed in different parts differently than as described. Of the various possible variants, only a few are referred to below.

Obwohl das zeitweilige Anhaften der Produkte 4 in ihrem freiliegenden Bereich B am Transportband 7 mittels Unterdruck auf besonders einfache Weise bewerkstelligt werden kann, ist es selbstverständlich möglich, eine kurzzeitige Mitnahme der Druckprodukte 4 durch das Transportband 7 auf andere geeignete Weise sicherzustellen.Although the temporary adhesion of the products 4 in their exposed area B to the conveyor belt 7 can be accomplished in a particularly simple manner by means of negative pressure, it is of course possible to ensure that the printed products 4 are temporarily carried along by the conveyor belt 7 in another suitable manner.

Im weiteren ist es denkbar, die gesamte Rückhalteeinrichtung 6 anders als wie dargestellt auszubilden. So kann beispielsweise ein Rückhalteelement vorgesehen werden, das jeweils das obere Produkt 4 eines Produktepaketes 3 zurückhält und an einer Weiterbewegung zusammen mit dem unteren Druckprodukt 5 hindert. Die Freigabe der Druckprodukte durch das Rückhalteelement kann ebenfalls durch das nachfolgende Druckproduktepaar 3 erfolgen. Daneben ist es auch möglich, eine Steuerung für dieses Rückhalteorgan vorzusehen.Furthermore, it is conceivable to design the entire restraint device 6 differently than shown. For example, a retaining element can be provided which retains the upper product 4 of a product package 3 and prevents further movement together with the lower printed product 5. The release of the printed products by the retaining element can also be carried out by the subsequent pair of printed products 3. In addition, it is also possible to provide a control for this restraint element.

Auf die beschriebene Weise ist es auch möglich, eine Schuppenformation zu verarbeiten, in der anders als wie bei der in den Fig. 1 bis 6 gezeigten Schuppenformation jedes Druckprodukt bzw. jedes Produktepaket dachziegelartig auf dem nachfolgenden Produkt bzw. Paket aufliegt. Bei einem derart ausgebildeten Schuppenstrom müsste jedoch die Verzögerungseinrichtung 6 unterhalb der Schuppenformation angeordnet werden, damit sie auf den Bereich der vorlaufenden Kante der Druckprodukte einwirken kann.In the manner described, it is also possible to process a scale formation in which, unlike the scale formation shown in FIGS. 1 to 6, each printed product or product package rests on the subsequent product or package in the manner of a roof tile. With such a shingled stream, however, the delay device 6 would have to be arranged below the shingled formation so that it can act on the area of the leading edge of the printed products.
