Abstract

Above a pile support (1) which is formed by revolvingly driven separating rollers (2), a cuboid pile space (12) for receiving a pile of folded printed products (14) is arranged. The pile space (12) is inclined with one corner (12a) pointing towards the direction of movement (A) of the separating rollers (2). In the region of this corner (12a) of the pile space (12), a suction member (18) is arranged, which can periodically be moved in between two neighbouring separating rollers (2) to grasp and to draw through the corner of the respective lowest printed product (14). The printed products (14), which are freed from the pile by the separating rollers (2) which are moved along the pile base, are placed on a removal conveyor (24), lying on top of one another in the manner of roof tiles. The pile space (12) is inclined with another corner (12b) pointing in the conveying direction (C) of the removal conveyor (24) in such a manner that a shingled formation (S) is formed on the removal conveyor (24), in which the printed products (14) are arranged with one corner (25) leading. At the side of the shingled formation (S), two corners (26, 27) of each printed product (14) are exposed, at which individual printed products (14''') can be grasped and e.g. laterally removed. <IMAGE>

Description

Die vorliegende Erfindung betrifft ein Verfahren, sowie eine Vorrichtung zum Weiterverarbeiten von gestapelten, vorzugsweise gefalteten Druckereierzeugnissen, gemäss Oberbegriff des Anspruches 1 bzw. des Anspruches 6.The present invention relates to a method and a device for further processing of stacked, preferably folded printed products, according to the preamble of claim 1 and claim 6.

Aus der CH-PS 598 106 und der entsprechenden US-PS 4 127 262 ist eine Vorrichtung zum Weiterverarbeiten von gestapelten Druckereierzeugnissen dieser Art bekannt. Bei dieser Vorrichtung wird jeweils das unterste Druckereier­zeugnis im Stapel im Bereich einer Ecke mittels eines Saugkopfes erfasst und zwischen zwei Trennwalzen hindurch­gezogen, die entlang der Stapelgrundfläche bewegt werden und Teil einer Stapelauflage bilden. Durch die zwischen das unterste Druckereierzeugnis und das darüberliegende Druckereierzeugnis einfahrende Trennwalze wird das unter­ste Druckereierzeugnis vom Stapel abgelöst und fällt auf einen Wegförderer, der unterhalb des Stapels angeordnet ist. Dabei ist der Stapel so ausgerichtet, dass er mit zwei Seitenkanten rechtwinklig zur Förderrichtung des Weg­förderers steht. Die derart abgelösten Druckereierzeug­nisse werden durch den Wegförderer in einer Schuppenforma­tion weggeführt, in der die Druckereierzeugnisse dachzie­gelartig übereinander liegen und mit ihren vorlaufenden Kanten rechtwinklig zur Förderrichtung des Wegförderers verlaufen.From CH-PS 598 106 and the corresponding US-PS 4 127 262 a device for further processing of stacked printed products of this type is known. In this device, the lowest printed product in the stack is detected in the area of a corner by means of a suction head and drawn between two separating rollers which are moved along the base of the stack and form part of a stack support. As a result of the separating roller moving between the lowermost printed product and the printed product lying above it, the lowermost printed product is detached from the stack and falls onto a conveyor which is arranged below the stack. The stack is aligned so that it has two side edges that are perpendicular to the conveying direction of the conveyor. The printed products thus detached are carried away by the conveyor in a scale formation in which the printed products lie on top of one another in the manner of roof tiles and with their leading edges run at right angles to the conveying direction of the conveyor.

In der Praxis hat sich bei dieser Vorrichtung gezeigt, dass der Stapel gegenüber der Förderrichtung des Wegför­derers um einen kleinen Winkel von einigen Graden ge­schwenkt werden muss, um auf dem Wegförderer die ge­wünschte Schuppenformation zu bilden, in der, wie bereits erwähnt, die Druckereierzeugnisse mit der vorlaufenden Kante rechtwinklig zur Förderrichtung des Wegförderers verlaufen. Diese leichte Schrägstellung des Stapels ist deswegen erforderlich, weil mit dem Trennen der Drucke­reierzeugnisse an einer Ecke derselben begonnen wird und das Ablösen der Druckereierzeugnisse in einer Richtung fortgesetzt wird, die quer zur Förderrichtung des Weg­förderers verläuft, was bedeutet, dass die einzelnen Be­reiche der abgelösten Druckereierzeugnisse nacheinander auf dem Wegförderer zur Auflage kommen. Solche Vorrich­tungen mit gegenüber der Förderrichtung des Wegförderers leicht schräg gestelltem Stapel werden von der Firma Ferag AG unter der Bezeichnung "Schnellanleger RA" (High-Speed Hopper RA) vertrieben.In practice, this device has shown that the stack has to be pivoted by a small angle of a few degrees in relation to the conveying direction of the conveyor in order to form the desired scale formation on the conveyor in which, as already mentioned, the printed products run with the leading edge at right angles to the conveying direction of the conveyor. This slight inclination of the stack is necessary because the separation of the printed matter begins at a corner thereof and the detachment of the printed matter is continued in a direction which is transverse to the conveying direction of the conveyor, which means that the individual areas of the detached printed matter come to rest one after the other on the conveyor. Such devices with a stack that is slightly inclined with respect to the conveying direction of the conveyor are sold by Ferag AG under the name "Schnellanleger RA" (High-Speed Hopper RA).

Die vorstehend beschriebenen Vorrichtungen haben den Vor­teil einer hohen Abbauleistung, sind jedoch mit dem Nach­teil behaftet, dass der Zugriff zu den einzelnen Drucke­reierzeugnissen im Schuppenverband zwecks individueller Verarbeitung der Druckereierzeugnisse mit einem gewissen Aufwand verbunden ist.The devices described above have the advantage of high degradation performance, but have the disadvantage that access to the individual printed products in the shed formation is associated with a certain outlay for the purpose of individual processing of the printed products.

Daneben ist eine Vorrichtung ähnlicher Art bekannt (CH-PS 637 087), die jedoch von etwas anderer Konstruktion ist und bei der der Stapel weder zur Bewegungsrichtung der die Stapelauflage bildenden Trennwalzen noch zur Förderrich­tung des Wegförderers schräg gestellt ist.In addition, a device of a similar type is known (CH-PS 637 087), but which is of a slightly different construction and in which the stack is not inclined neither to the direction of movement of the separating rollers forming the stack support nor to the conveying direction of the conveyor.

Im weiteren ist aus der GB-PS 829 518 eine Vorrichtung zum Abziehen des jeweils untersten Blattes von einem Stapel bekannt, bei der das unterste Blatt durch einen Saugkopf erfasst und nach unten in den Wirkbereich von zwei Abzugs­rollen gezogen wird. Der Blattstapel ist gegenüber der Ab­zugsrichtung der Rollen schräg gestellt, so dass die Blät­ter mit der vorgängig vom Saugkopf erfassten Ecke voraus durch die Abzugsrollen wegtransportiert werden. Die Blät­ter werden einzeln und nacheinander abgezogen und wegge­führt, wodurch die Abbauleistung gegenüber den vorstehend erwähnten bekannten Vorrichtungen geringer ist.Furthermore, from GB-PS 829 518 a device for pulling off the bottom sheet from a stack is known, in which the bottom sheet is gripped by a suction head and pulled down into the effective area by two take-off rollers. The stack of sheets is inclined with respect to the direction in which the rollers are drawn off, so that the sheets are transported away by the removal rollers with the corner previously gripped by the suction head. The sheets are pulled off and carried away one by one and one after the other, as a result of which the degradation performance is lower compared to the known devices mentioned above.

Der vorliegenden Erfindung liegt nun die Aufgabe zugrunde, ein Verfahren und eine Vorrichtung der eingangs genannten Art zu schaffen, welches bzw. die bei hoher Leistung ein leichteres Ver- und Bearbeiten einzelner Druckprodukte im weggeführten Schuppenverband erlaubt als dies mit den ein­gangs erläuterten, bekannten Vorrichtungen möglich ist.The present invention is based on the object of creating a method and a device of the type mentioned at the outset, which, at high output, allows easier processing and processing of individual printed products in the removed scale structure than is possible with the known devices explained at the outset is.

Diese Aufgabe wird erfindungsgemäss durch die Merkmale des kennzeichnenden Teiles des Anspruches 1 bzw. des Anspru­ches 6 gelöst.This object is achieved according to the invention by the features of the characterizing part of claim 1 and of claim 6.

Dadurch, dass die Druckereierzeugnisse nach wie vor mit gegenseitiger Überlappung auf den Wegförderer aufgelegt werden, jedoch so, dass alle Seitenkanten der Druckerei­erzeugnisse quer zur Förderrichtung des Wegförderers ver­laufen und eine Ecke in Richtung der Wegförderrichtung weist, ist einerseits ein einwandfreies Wegfördern der in rascher Folge vom Stapel abgelösten Druckereierzeugnisse gewährleistet und andererseits ein leichter Zugriff zu den einzelnen Druckereierzeugnissen möglich. In der weggeführ­ ten Schuppenformation liegen nämlich die Bereiche von zwei Ecken jedes Druckereierzeugnisses sowie gewisse Bereiche von Seitenkanten vollständig frei. Dies erlaubt ein prob­lemloses Angreifen an den einzelnen Druckereierzeugnissen.The fact that the printed products are still placed on the conveyor with mutual overlap, but in such a way that all side edges of the printed products run transversely to the conveying direction of the conveyor and have a corner in the direction of the conveying direction, is on the one hand a perfect conveying away in rapid succession from Stack of detached printed matter guaranteed and on the other hand easy access to the individual printed matter possible. In the away In fact, the scale formation means that the areas of two corners of each printed product and certain areas of side edges are completely exposed. This allows easy handling of the individual printed products.

Bevorzugte Ausgestaltungen des erfindungsgemässen Verfah­rens bzw. der erfindungsgemässen Vorrichtung bilden Gegen­stand der abhängigen Ansprüche.Preferred embodiments of the method according to the invention and the device according to the invention form the subject of the dependent claims.

Die in den Figuren dargestellte Vorrichtung weist eine Stapelauflage 1 auf, welche durch in gegenseitigen Abstän­den angeordnete, zueinander parallele Trennwalzen 2 gebil­ det wird. Die Walzen 2 sind an ihren Enden an einer Kette 3 bzw. 4 befestigt, die in einem Kettenkanal 5 (siehe Fig. 2) verläuft. Die endlosen Ketten 3, 4 sind um Umlenkräder 6 bzw. 7 geführt, von denen ein Umlenkrad auf nicht darge­stellte Weise angetrieben ist. Die Trennwalzen 2 werden somit entlang einer geschlossenen Umlaufbahn in Richtung des Pfeiles A umlaufend angetrieben.The device shown in the figures has a stack support 1, which is formed by mutually parallel, mutually parallel separation rollers 2 det. The rollers 2 are fastened at their ends to a chain 3 or 4 which runs in a chain channel 5 (see FIG. 2). The endless chains 3, 4 are guided around deflection wheels 6 and 7, of which a deflection wheel is driven in a manner not shown. The separating rollers 2 are thus driven all the way along a closed orbit in the direction of arrow A.

Oberhalb der Stapelauflage 1 befindet sich ein Stapeltisch 8 mit Anschlägen 9, 10, 11, von denen die Anschläge 9 und 10 als Eckanschläge ausgebildet sind.

Der Stapelraum 12 dient zur Aufnahme eines Stapels 13 von gefalteten Druckereierzeugnissen 14, z.B. Zeitungen, Zeit­schriften und Teilen hievon (Fig. 2). In den Figuren ist die Falzkante dieser Druckereierzeugnisse 14 mit 14a be­zeichnet, während deren Seitenkanten mit 14b und 14c sowie deren offene Seite mit 14d bezeichnet sind. Der Eckan­schlag 9 ist feststehend, während die Anschläge 10 und 11 mittels eines Verstellmechanismus 15 bzw. 16 verstellt werden können, um die Grösse des Stapelraumes 12 an das Format des jeweils zu verarbeitenden Druckereierzeugnisses 14 anpassen zu können.Above the stacking support 1 there is a stacking table 8 with stops 9, 10, 11, of which the stops 9 and 10 are designed as corner stops. These stops 9, 10, 11 define a cuboid stacking space 12 (FIG. 1), which is inclined with a corner 12a pointing towards the direction of movement A of the separating rollers 2. This inclination of the stacking space 12 is shown in Fig. 1 by the angle α. This angle α is approximately 20 °. The stacking space 12 serves to hold a stack 13 of folded printed products 14, e.g. Newspapers, magazines and parts thereof (Fig. 2). In the figures, the fold edge of these printed products 14 is designated by 14a, while their side edges are designated by 14b and 14c and their open side by 14d. The corner stop 9 is fixed, while the stops 10 and 11 can be adjusted by means of an adjusting mechanism 15 and 16, respectively, in order to be able to adapt the size of the stacking space 12 to the format of the printed product 14 to be processed.

Die Trennwalzen 2 bewegen sich während ihres Umlaufes in Richtung des Pfeiles A entlang der Grundfläche 13a des Stapels 13 (Fig. 2) und wälzen sich am jeweils untersten Druckereierzeugnis 14 im Stapel 13 ab. Die Drehrichtung der Trennwalzen 2 ist in Fig. 2 mit dem Pfeil B bezeich­ net. Dabei ist es erforderlich, dass die Umfangsgeschwin­digkeit der Trennwalzen 2 deren Vorschubgeschwindigkeit entspricht. Um dies zu erreichen, ist benachbart zu einer Kette eine Reibleiste vorgesehen, die in Fig. 1 nur sche­matisch dargestellt und mit 17 bezeichnet ist. Die Trenn­walzen 2 wälzen sich mit ihrem als Konus ausgebildeten En­de auf dieser Reibleiste 17 ab, welche auf nicht näher dargestellte Weise rechtwinklig zur Bewegungsrichtung A der Trennwalzen 2 verstellbar ist.The separating rollers 2 move during their rotation in the direction of arrow A along the base surface 13a of the stack 13 (FIG. 2) and roll on the lowest printed product 14 in the stack 13. The direction of rotation of the separating rollers 2 is indicated by the arrow B in FIG. 2 net. It is necessary that the peripheral speed of the separating rollers 2 corresponds to their feed speed. In order to achieve this, a friction bar is provided adjacent to a chain, which is shown only schematically in FIG. 1 and is designated by 17. The separating rollers 2 roll with their conical end on this friction bar 17, which is adjustable in a manner not shown at right angles to the direction of movement A of the separating rollers 2.

Unterhalb der vom Eckanschlag 9 festgelegten Ecke 12a des Stapelraumes 12 befindet sich ein Saugkopf 18, der am einen Ende eines Winkelhebels 19 befestigt ist (Fig. 2). Dieser Winkelhebel 19 ist am anderen Ende mittels einer Rolle 20 in einer Führungsschiene 21 geführt. Der Winkel­hebel 19 ist weiter mittels eines Gelenkes 22 mit einem Planetengetriebe 23 verbunden. Der Aufbau des Antriebes für den Saugkopf 18 und die dadurch erzeugte Bewegungsbahn des letzteren sind in der bereits früher erwähnten CH-PS 598 106 (bzw. der entsprechenden US-PS 4 127 262) ausführ­licher beschrieben. Der Saugkopf 18 ist weiter periodisch an eine nicht näher dargestellte Unterdruckquelle an­schliessbar.Below the corner 12a of the stacking space 12 defined by the corner stop 9 there is a suction head 18 which is attached to one end of an angle lever 19 (FIG. 2). This angle lever 19 is guided at the other end by means of a roller 20 in a guide rail 21. The angle lever 19 is further connected to a planetary gear 23 by means of a joint 22. The structure of the drive for the suction head 18 and the movement path of the latter generated thereby are described in more detail in the previously mentioned CH-PS 598 106 (or the corresponding US-PS 4 127 262). The suction head 18 can also be periodically connected to a vacuum source, not shown.

Der Saugkopf 18 fährt periodisch zwischen jeweils zwei be­nachbarte Trennwalzen 2 ein, erfasst eine Ecke 27 des un­tersten Druckereierzeugnisses 14′ und zieht diese Ecke 27 zwischen aufeinanderfolgenden Trennwalzen 2 hindurch, wie das in Fig. 2 dargestellt ist. Durch die in die Öffnung zwischen dem untersten Druckereierzeugnis 14′ und dem da­rüberliegenden Druckereierzeugnis 14˝ einfahrende Trenn­walze 2 wird das unterste Druckereierzeugnis 14′ vom Sta­ pel 13 abgelöst. Der Saugkopf 18 wird zu gegebener Zeit von der Unterdruckquelle abgetrennt und bewegt sich durch den Zwischenraum zwischen den beiden folgenden Trennwalzen 2 hindurch erneut nach oben, um das nächste Druckereier­zeugnis 14˝ zu erfassen, wie das in der erwähnten CH-PS 598 106 und der entsprechenden US-PS 4 127 262 ausführ­licher beschrieben ist. Die gegenüber der vorbekannten Vorrichtung, wie sie in den genannten Patentschriften ge­zeigt und beschrieben ist, weniger ausgeprägte Schrägstel­lung des Stapels 13 (α = ca. 20° im Vergleich zu etwa 45° bei der bekannten Vorrichtung) erleichtert das Abbiegen der vom Saugkopf 18 erfassten Ecke 27 und somit der Falz­kante 14a besonders bei dicken Druckereierzeugnissen 14.The suction head 18 moves periodically between two adjacent separating rollers 2, detects a corner 27 of the lowermost printed product 14 'and pulls this corner 27 between successive separating rollers 2, as shown in Fig. 2. Due to the separating roller 2 entering the opening between the lowermost printed product 14 'and the overlying printed product 14', the lowermost printed product 14 'from Sta pel 13 replaced. The suction head 18 is disconnected from the vacuum source at the appropriate time and moves up again through the space between the two following separating rollers 2 to detect the next printed product 14,, such as that in the aforementioned CH-PS 598 106 and the corresponding one U.S. Patent 4,127,262 is described in more detail. The less pronounced inclination of the stack 13 (α = approx. 20 ° compared to approx. 45 ° in the known device) compared to the previously known device, as shown and described in the aforementioned patents, makes it easier to bend the corner captured by the suction head 18 27 and thus the fold edge 14a, particularly in the case of thick printed products 14.

Unterhalb der Stapelauflage 1 und den Stapelraum 12 unter­greifend ist ein Wegförderer 24 angeordnet, dessen Förder­richtung C mit der Bewegungsrichtung A der Trennwalzen 2 einen Winkel β bildet (Fig. 1). Der Stapelraum 12 ist nun mit einer seiner Ecken 12b in Förderrichtung C des Wegför­derers 24 derart um einen Winkel γ (Fig. 1) schrägge­stellt, dass die vom Stapel 13 abgelösten Druckereierzeug­nisse 14 mit allen Seitenkanten 14a, 14b, 14c und 14d quer zur Förderrichtung C des Wegförderers 24 verlaufend auf diesen Wegförderer 24 bzw. dachziegelartig auf das vor­gängig abgelöste Druckereierzeugnis 14 aufgelegt werden, wie das insbesondere aus der Grundrissfigur 1 deutlich hervorgeht. Diese Schrägstellung des Stapelraumes 12 be­züglich der Förderrichtung C des Wegförderers 24 wird nun so gewählt, dass der erwähnte Winkel γ grösser als unge­fähr 15° ist. Vorzugsweise wird der Stapelraum 12 derart schräggestellt, dass dieser Winkel γ zwischen ungefähr 30° und 60° und insbesondere zwischen etwa 30° und 45° liegt.A conveyor 24 is arranged below the stacking support 1 and under the stacking space 12, the conveying direction C of which forms an angle β with the direction of movement A of the separating rollers 2 (FIG. 1). The stacking space 12 is now inclined with one of its corners 12b in the conveying direction C of the conveyor 24 by an angle γ (FIG. 1) such that the printed products 14 detached from the stack 13 with all side edges 14a, 14b, 14c and 14d transversely to the conveying direction C. of the conveyor 24 running on this conveyor 24 or in the manner of a roof tile on the previously detached printed product 14, as can be seen particularly clearly in plan view 1. This inclination of the stacking space 12 with respect to the conveying direction C of the conveyor 24 is now selected such that the angle γ mentioned is greater than approximately 15 °. The stacking space 12 is preferably inclined such that this angle γ is between approximately 30 ° and 60 ° and in particular between approximately 30 ° and 45 °.

Wie die Fig. 1, 2 und 4 zeigen, werden die Druckereier­zeugnisse 14 sich überlappend auf dem Wegförderer 24 ab­gelegt und von diesem in einer Schuppenformation S wegge­führt, in der die eine Ecke 25 der Druckereierzeugnisse 14 vorausläuft. Wie aus der Fig. 1 deutlich hervorgeht, lie­gen in dieser weggeführten Schuppenformation S zwei Ecken 26 und 27 vollständig frei, die sich seitlich der Schup­penformation S befinden. Im weiteren ist die Falzkante 14a und eine Seitenkante 14b vollständig und die andere Sei­tenkante 14c, sowie die offene Seite 14d nur teilweise zu­gänglich. Bei jedem Druckereierzeugnis 14 ist ein L-förmi­ger Bereich 28 nicht vom nächsten, darüberliegenden Druckereierzeugnis 14 überdeckt. Dieser Bereich 28 ist so­mit ebenfalls zugänglich.1, 2 and 4 show, the printed products 14 are placed overlapping on the conveyor 24 and guided away from it in a scale formation S, in which one corner 25 of the printed products 14 runs ahead. As is clear from FIG. 1, two corners 26 and 27, which are located to the side of the scale formation S, are completely exposed in this scale formation S which is carried away. Furthermore, the folded edge 14a and one side edge 14b are completely accessible and the other side edge 14c and the open side 14d are only partially accessible. For each printed product 14, an L-shaped area 28 is not covered by the next printed product 14 lying above it. This area 28 is thus also accessible.

Dies ist im Gegensatz zur bereits erwähnten Vorrichtung gemäss CH-PS 598 106 (bzw. der entsprechenden US-PS 4 127 262), bei der die vom Stapel abgelösten Druckereier­zeugnisse in einer Schuppenformation weggeführt werden, in der die vorlaufende Kante der Druckereierzeugnisse recht­winklig zur Förderrichtung des Wegförderers verläuft und in der alle Ecken der Druckereierzeugnisse entweder auf dem vorauslaufenden Druckereierzeugnis aufliegen oder vom nächstfolgenden Druckereierzeugnis überdeckt sind.This is in contrast to the already mentioned device according to CH-PS 598 106 (or the corresponding US-PS 4 127 262), in which the printed products detached from the stack are led away in a scale formation in which the leading edge of the printed products is perpendicular to the conveying direction of the conveyor and in which all corners of the printed products either rest on the preceding printed product or are covered by the next printed product.

Da wie erwähnt, die beiden seitlich der Schuppenformation S liegenden Ecken 26 und 27 jedes Druckereierzeugnisses 14 nicht mit einem anderen Druckereierzeugnis in Berührung stehen, kann im Bereich dieser Ecken 26, 27 ohne Schwie­rigkeiten einzeln auf die Druckereierzeugnisse 14 einge­wirkt werden. So ist es z.B. möglich, an einer entlang des Wegförderers 24 angeordneten, nur schematisch dargestell­ten Entnahmestation 29 (Fig. 1) einzelne Erzeugnisse 14 im Bereich der Ecke 27 von Hand oder mit mechanischen Mitteln zu erfassen und in Richtung des Pfeiles D seitlich aus der Schuppenformation S herauszuziehen. Auf diese Weise können der Schuppenformation S sehr einfach einzelne Druckereier­zeugnisse 14 entnommen werden, wie das in Fig. 1 durch das gestrichelt dargestellte Druckereierzeugnis 14‴ darge­stellt ist. Da der durch das nachfolgende Druckereierzeug­nis 14 nicht überdeckte Bereich 28 jedes Druckereierzeug­nisses 14 verhältnismässig gross ist, lässt sich das der Schuppenformation S zu entnehmende Druckereierzeugnis 14 im Schuppenverband leicht optisch identifizieren. Dadurch ist es möglich, manuell oder maschinell problemlos gewisse Druckereierzeugnisse 14 aus der Schuppenformation S′ aus­zuscheiden.Since, as mentioned, the two corners 26 and 27 of each printed product 14 lying to the side of the scale formation S are not in contact with another printed product, it is possible to act individually on the printed products 14 in the region of these corners 26, 27 without difficulty. So it is possible, for example, on one along the Removal conveyor 24 arranged, only schematically shown removal station 29 (FIG. 1) to grasp individual products 14 in the area of the corner 27 by hand or with mechanical means and to pull them laterally out of the scale formation S in the direction of the arrow D. In this way, individual printed products 14 can be removed from the scale formation S very easily, as is shown in FIG. 1 by the printed product 14 dargestellte shown in broken lines. Since the area 28 of each printed product 14 which is not covered by the subsequent printed product 14 is relatively large, the printed product 14 which can be seen from the scale formation S can be easily identified optically in the scale structure. This makes it possible to manually or mechanically easily remove certain printed products 14 from the scale formation S '.

Das Ablegen der vom Stapel 13 abgelösten Druckereierzeug­nisse 14 in der in der Fig. 1 dargestellten Schuppenforma­tion S hat noch den weiteren Vorteil, dass die Höhe H der Schuppenformation im Bereich der Ecke 12a des Stapelraumes 12 verhältnismässig gering ist (siehe Fig. 4). Das ermög­licht es, den Wegförderer 24 vergleichsweise nahe an der Stapelunterseite 13a anzuordnen, so dass die Fallhöhe der abgelösten Druckereierzeugnisse 14 möglichst klein wird.Placing the printed products 14 detached from the stack 13 in the scale formation S shown in FIG. 1 has the further advantage that the height H of the scale formation in the region of the corner 12a of the stack space 12 is relatively low (see FIG. 4). This makes it possible to arrange the conveyor 24 comparatively close to the underside of the stack 13a, so that the drop height of the detached printed products 14 is as small as possible.

In Fig. 3 ist in einer der Fig. 1 entsprechenden Darstel­lung eine Variante der erfindungsgemässen Vorrichtung ge­zeigt, bei der das Ablösen der Druckereierzeugnisse vom Stapel 13 und das Ablegen der Druckereierzeugnisse 14 auf den Wegförderer 24 in einer Schuppenformation S gleich er­folgt wie das anhand der Fig. 1 erläutert worden ist. We­gen dieser Identität zwischen den Ausführungsformen gemäss den Fig. 1 und 3 sind in letzterer nicht mehr alle Bezugs­zeichen eingetragen.In FIG. 3, a representation corresponding to FIG. 1 shows a variant of the device according to the invention, in which the detachment of the printed products from the stack 13 and the depositing of the printed products 14 on the conveyor 24 in a scale formation S takes place in the same way as that with reference to FIG 1 has been explained. Because of this identity between the embodiments according to 1 and 3 are no longer all reference numerals entered in the latter.

Die Ausführungsform gemäss Fig. 3 unterscheidet sich von derjenigen gemäss Fig. 1 dadurch, dass dem Wegförderer 24 ein weiterer Wegförderer 30 und/oder 31 nachgeschaltet ist. Die Wegförderer 30, 31 weisen eine Förderrichtung E bzw. F auf, die mit der Förderrichtung C des ersten Weg­förderers 24 einen Winkel δ bzw. δ ′ bildet. Die Förder­richtung E bzw. F der nachgeschalteten Wegförderer 30, 31 ist bezüglich der Förderrichtung C des ersten Wegförderers 24 so gewählt, dass in der durch diese nachgeschalteten Wegförderer 30, 31 weggeführten Schuppenformation S′ die Druckereierzeugnisse 14 eine Lage einnehmen, in der die vorlaufenden Kanten 14a bzw. 14b rechtwinklig zur Förder­richtung E bzw. F der Wegförderer 30 bzw. 31 steht. Somit kann aus der vom Wegförderer 24 geförderten Schuppenfor­mation S auf einfache Weise eine "Normal"-Schuppenforma­tion S′ gebildet werden, wie sie häufig für eine Weiter­verarbeitung benötigt wird. Es ist noch darauf hinzuwei­sen, dass in der durch den Wegförderer 30 weggeführten Schuppenformation S′ die vorlaufende Kante der Druckerei­erzeugnisse 14 durch die Falzkante 14a gebildet wird, wäh­rend in der Schuppenformation S′, die vom anderen Wegför­derer 31 weggeführt wird, die vorlaufende Kante durch die Seitenkante 14b gebildet wird.The embodiment according to FIG. 3 differs from that according to FIG. 1 in that the removal conveyor 24 is followed by a further removal conveyor 30 and / or 31. The conveyors 30, 31 have a conveying direction E or F, which forms an angle δ or δ 'with the conveying direction C of the first conveyor 24. The conveying direction E or F of the downstream conveyors 30, 31 is selected with respect to the conveying direction C of the first conveyer 24 such that in the shingled formation S 'carried away by these downstream conveyors 30, 31, the printed products 14 assume a position in which the leading edges 14a and 14b is perpendicular to the conveying direction E and F of the conveyors 30 and 31, respectively. Thus, a "normal" scale formation S 'can be formed in a simple manner from the scale formation S conveyed by the conveyor 24, as is often required for further processing. It should also be noted that in the scale formation S 'carried away by the conveyor 30, the leading edge of the printed products 14 is formed by the folded edge 14a, while in the scale formation S', which is led away from the other conveyor 31, the leading edge by the Side edge 14b is formed.

Bei beiden gezeigten Ausführungsformen ist der Wegförderer 24 so angeordnet, dass die Druckereierzeugnisse 14 mit der Ecke 25 vorauslaufend weggeführt werden. Es ist jedoch durchaus möglich, den Wegförderer 24 mit gegenüber der Förderrichtung C entgegengesetzter Förderrichtung anzuord­ nen, so dass die Druckereierzeugnisse mit ihrer der Ecke 25 gegenüberliegenden Ecke vorauslaufend und der offenen Seite 14d voran weggeführt werden.In both embodiments shown, the conveyor 24 is arranged such that the printed products 14 are led away with the corner 25 in advance. However, it is entirely possible to arrange the conveyor 24 with a conveying direction opposite to the conveying direction C. NEN, so that the printed products are led away with their corner opposite to the corner 25 and the open side 14d ahead.

Daneben wäre es auch möglich, den Wegförderer 24 gegenüber der in den Fig. 1 und 3 gezeigten Lage um 90° zu drehen, um so die Druckereierzeugnisse 14 mit den Ecken 26 bzw. 27 vorauslaufend wegführen zu können. Doch sind bei einer solchen Variante gegenüber den gezeigten Ausführungsformen konstruktive Änderungen am Trennwalzenumlauf nötig.In addition, it would also be possible to rotate the conveyor 24 by 90 ° with respect to the position shown in FIGS. 1 and 3, so that the printed products 14 with the corners 26 and 27 can be led away in advance. However, in the case of such a variant, structural changes to the separation roller circulation are necessary compared to the embodiments shown.
