Description

Die vorliegende Erfindung betrifft eine Vorrichtung zum Zubringen von in einer Schuppenformation anfallenden, vorzugsweise gefalteten Druckereierzeugnissen zu einer Weiterverarbeitungsstelle.The present invention relates to a device for Delivery of accumulations in a scale formation, preferably folded printed matter to a finishing station.

Eine Vorrichtung dieser Art ist in der älteren EP-A 0 755 886 offenbart. Sie weist oberhalb einer Stapelstelle, an der aus mittels einer ersten Fördereinrichtung zugeführten Druckereierzeugnissen ein Zwischenstapel gebildet wird, ein angetriebenes, von einem Anpressband umgriffenes Förderrad auf, das mehrere am Umfang gleichmässig verteilte Ausnehmungen aufweist. Eine ebenfalls oberhalb der Stapelstelle angeordnete und synchron mit dem Förderrad angetriebene Saugeranordnung ist dazu bestimmt, das jeweils oberste Druckereierzeugnis des Zwischenstapels von diesem abzuheben und mit einem an eine Kante des Druckereierzeugnisses anschliessenden Bereich in die betreffende Ausnehmung des Förderrades einzuführen, welches das Druckereierzeugnis durch Biegen in den vom Förderrad und Anpressband gebildeten Förderspalt lenkt. Bei dieser bekannten Vorrichtung muss die Saugeranordnung die genannte Kante des in den Wirkbereich des Förderrades verbrachten Druckereierzeugnisses umfahren, was eine gewisse Zeit beansprucht. Überdies werden die Druckereierzeugnisse mittels des Förderrades erheblich gebogen, was wegen der Verletzungsgefahr der Druckereierzeugnisse nicht mit beliebig hoher Geschwindigkeit gemacht werden kann.

In the scale formation S 1 , each printed product lies on the trailing one, which enables the formation of an intermediate stack 16 loaded from below at the stacking point 14.

Die Schuppenformation S1 kann Unregelmässigkeiten aufweisen, d.h. der Abstand A zwischen einander entsprechenden Kanten aufeinanderfolgender Druckereierzeugnisse 12 kann unterschiedlich sein, es können zwei oder mehr Druckereierzeugnisse 12 deckungsgleich aufeinander liegen oder es können Lücken vorhanden sein.The scale formation S 1 can have irregularities, ie the distance A between corresponding edges of successive printed products 12 can be different, two or more printed products 12 can be congruent with one another or there can be gaps.

Oberhalb der Stapelstelle 14 ist eine Saugeranordnung 18, wie sie beispielsweise aus der EP-A-0 628 505 bekannt ist, angeordnet. Bezüglich des Aufbaus und der Funktionsweise der Saugeranordnung 18 wird ausdrücklich auf dieses Dokument verwiesen. Die Saugeranordnung 18 weist einen Rotor 22 auf, der über einen Riementrieb 24 mit einem Antriebsmotor 25 verbunden ist und an dem drei parallel zur Drehachse 22' des Rotors 22 verlaufende Achsen 26 frei drehbar gelagert sind. Die Achsen 26 sind in gleichem Abstand zur Drehachse 22' und in Umfangsrichtung gleichmässig verteilt angeordnet. Am freien Ende jeder Achse 26 ist mit dieser drehfest ein Schwenkarm 28 verbunden, der zwei Saugköpfe 30 trägt. Der Rotor 22 ist in einem an einem Maschinengestell 20 befestigten Gehäuse 32 drehbar gelagert, in welchem eine nicht dargestellte Steuereinrichtung zum Verschwenken der Achsen 26 in Abhängigkeit von der Drehlage des Rotors 22 angeordnet ist. Die Saugeranordnung 18 ist dazu bestimmt, beim Drehen des Rotors 22 in Pfeilrichtung D sich mit den einer Achse 26 zugeordneten Saugköpfen 30 von oben an das jeweils oberste Druckereierzeugnis 12 des Zwischenstapels 16, benachbart zu einer Kante 34 des Druckereierzeugnisses 12, anzulegen und das erfasste Druckereierzeugnis 12 von dieser Kante 34 her vom darunterliegenden Druckereierzeugnis 12 des Zwischenstapels 16 abzuheben, wobei die Druckereierzeugnisse 12 relativ zueinander praktisch nicht verschoben werden. Mittels der Saugeranordnung 18 wird das erfasste Druckereierzeugnis 12 mit seiner Kante 34 in den Wirkbereich einer synchron zur Saugeranordnung 18 angetriebenen, ebenfalls oberhalb der Stapelstelle 14 angeordneten Stossanordnung 36 verbracht.Above the stacking point 14 there is a suction arrangement 18, as is known for example from EP-A-0 628 505, arranged. Regarding the structure and functionality the suction arrangement 18 is expressly referred to this document referred. The suction arrangement 18 has a rotor 22 on, via a belt drive 24 with a drive motor 25 is connected and on which three parallel to the axis of rotation 22 'of the rotor 22 extending axes 26 freely rotatable are stored. The axes 26 are at the same distance from Axis of rotation 22 'and evenly distributed in the circumferential direction arranged. At the free end of each axis 26 is with this rotatably connected to a swivel arm 28, the two suction heads 30 wears. The rotor 22 is in a on a machine frame 20 attached housing 32 rotatably mounted in which a control device, not shown, for pivoting of the axes 26 as a function of the rotational position of the rotor 22 is arranged. The suction arrangement 18 is intended for when rotating the rotor 22 in the direction of the arrow D with the suction heads 30 assigned to an axis 26 from the top to the top printed product 12 of each Intermediate stack 16, adjacent to an edge 34 of the Printed product 12 to create and the captured Printed product 12 from this edge 34 from below Printed product 12 of the intermediate stack 16 stand out, with the printed products 12 relative practically not shifted towards each other. By means of the Suction device arrangement 18 becomes the detected printed product 12 with its edge 34 in the effective range of a synchronous Suction arrangement 18 driven, also above the Stacking point 14 arranged push assembly 36 spent.

Die Stossanordnung 36 weist eine über einen weiteren Riementrieb 24' mit dem Antrieb 25 verbundene, gleichsinnig zur Drehrichtung D drehend angetriebene Nockenwalze 38 mit in Umfangsrichtung gleichmässig verteilten nockenartigen Vorsprüngen 40 auf. Die in Drehrichtung D gesehen vorlaufende Flanke 42 jedes Vorsprungs 40 schliesst mit dem wenigstens annähernd kreisrunden Walzenkern 44 einen spitzen Winkel α ein. Der vom Walzenkern 44 und der vorlaufenden Flanke 42 gebildete Kantenbereich bildet einen Anschlag 46 für die Kante 34 des betreffenden Druckereierzeugnisses 12. Die Anschläge 46 laufen somit entlang der geschlossenen Umlaufbahn 48 um und sind in konstantem Abstand hintereinander angeordnet.The push arrangement 36 has one via a further belt drive 24 'connected in the same direction to the drive 25 to the direction of rotation D driven cam roller 38 with cam-like evenly distributed in the circumferential direction Projections 40 on. The leading one in direction of rotation D. Flank 42 of each projection 40 closes with the at least approximately circular roller core 44 a acute angle α. That of the roll core 44 and the leading one Edge 42 formed edge area forms a Stop 46 for the edge 34 of the printed product in question 12. The stops 46 thus run along the closed orbit 48 um and are at a constant distance arranged one behind the other.

Die Vorsprünge 40 bilden weiter mit ihrer vorlaufenden Flanke 42 ein Stützelement 50 zum Untergreifen des jeweiligen Druckereierzeugnisses 12, um dieses am Herunterfallen nach der Freigabe durch die Saugeranordnung 18 zu hindern.The projections 40 continue to form with their leading Flank 42 a support element 50 for reaching under each Printed matter 12 to keep it from falling after release by the suction arrangement 18 prevent.

Rechtwinklig zur Förderrichtung F1 gesehen, befindet sich die Nockenwalze 38 etwa mittig des Zwischenstapels 16, wogegen die Saugköpfe 30 in geringem Abstand zur Nockenwalze 38 seitlich versetzt umlaufen. Seen at right angles to the conveying direction F 1 , the cam roller 38 is located approximately in the middle of the intermediate stack 16, whereas the suction heads 30 rotate laterally offset at a small distance from the cam roller 38.

In Förderrichtung F1 gesehen, ist der Stapelstelle 14 eine zweite Fördereinrichtung 52 nachgelagert. Das diesseitige Ende der als Bandförderer 54 ausgebildeten zweiten Fördereinrichtung 52 befindet sich benachbart zur Oberseite des Zwischenstapels 16 und sein von der Stapelstelle 14 entferntes Ende befindet sich bei der mit dem Bezugszeichen 56 angedeuteten Weiterverarbeitungsstelle. Der Antrieb der zweiten Fördereinrichtung 52 ist mit der Drehzahl des Antriebsmotors 25 abgestimmt.Seen in the conveying direction F 1 , the stacking point 14 is followed by a second conveying device 52. The end on this side of the second conveyor 52 designed as a belt conveyor 54 is located adjacent to the upper side of the intermediate stack 16 and its end remote from the stacking point 14 is located at the further processing point indicated by reference number 56. The drive of the second conveyor 52 is coordinated with the speed of the drive motor 25.

Das Zusammenwirken zwischen der Saugeranordnung 18 und Stossanordnung 36 ist insbesondere aus den Fig. 3 und 4 erkennbar, in welcher der Einfachheit halber neben dem Zwischenstapel 16 und dem Bandförderer 54 nur vereinfacht die Saugeranordnung 18 und die Nockenwalze 38 gezeigt sind. In diesen Figuren ist auch die birnenartige Bewegungsbahn 58 der Saugköpfe 30 strichpunktiert angedeutet. Diese legt mit einer gegen unten gerichteten Spitze eine Erfassungsstelle für die Druckereierzeugnisse 12 fest und schneidet, in Ansicht gesehen, die Umlaufbahn 48 der Anschläge 46.The interaction between the suction arrangement 18 and The push arrangement 36 is in particular from FIGS. 3 and 4 recognizable in which, for the sake of simplicity, next to the Intermediate stack 16 and the belt conveyor 54 only simplified the suction arrangement 18 and the cam roller 38 are shown are. The pear-like trajectory is also in these figures 58 of the suction heads 30 indicated by dash-dotted lines. This lays one with a point pointing downwards Detection point for the printed products 12 fixed and intersects, seen in view, the orbit 48 of the stops 46.

Wie der Fig. 4 entnehmbar ist, legt sich jeweils ein Paar Saugköpfe 30 bei der Erfassungsstelle von oben an die Flachseite des obersten Druckereierzeugnisses 12 des Zwischenstapels 16, benachbart zur in Förderrichtung F2 gesehen nachlaufenden Kante 34, an und saugt sich infolge der Verbindung zu einer Unterdruckquelle an diesen fest (Fig. 4). Im Zuge der Weiterdrehung in Drehrichtung D des Rotors 22 bewegt sich das betreffende Paar Saugköpfe 30 entlang einem wenigstens annähernd kreisförmigen Abschnitt der Bewegungsbahn 58 in Richtung zum Schnittpunkt der Bewegungsbahn 58 und der Umlaufbahn 48 der Anschläge 46, in dessen Nähe eine Abgabestelle für das jeweils von der Saugeranordnung 18 gehaltene Druckereierzeugnis 12 angeordnet ist. Die ebenfalls in Drehrichtung D angetriebene Nockenwalze 38 untergreift nun mit einem Vorsprung 40 dieses Druckereierzeugnis 12 (Fig. 3), wonach die betreffenden Saugköpfe 30 von der Unterdruckquelle getrennt werden. Dadurch, dass der Radius des im wesentlichen kreisförmigen Abschnitts der Bewegungsbahn 58 wesentlich kleiner ist als die Abmessung der Druckereierzeugnisse 12 in Förderrichtung F2 gesehen, behalten diese beim Abheben ab dem Zwischenstapel 16 in Förderrichtung F2 ihre Lage im wesentlichen bei.As can be seen in FIG. 4, a pair of suction heads 30 lies at the detection point from above on the flat side of the uppermost printed product 12 of the intermediate stack 16, adjacent to the trailing edge 34 seen in the conveying direction F 2 , and is sucked in as a result of the connection a vacuum source attached to this (Fig. 4). In the course of the further rotation in the direction of rotation D of the rotor 22, the pair of suction heads 30 in question moves along an at least approximately circular section of the movement path 58 in the direction of the intersection of the movement path 58 and the orbit 48 of the stops 46, in the vicinity of which a delivery point for the respective of the suction device 18 held printed product 12 is arranged. The cam roller 38, which is also driven in the direction of rotation D, now engages under this projection 40 with a projection 40 (FIG. 3), after which the relevant suction heads 30 are separated from the vacuum source. Because the radius of the essentially circular section of the movement path 58 is substantially smaller than the dimension of the printed products 12 seen in the conveying direction F 2 , they essentially maintain their position when they are lifted off the intermediate stack 16 in the conveying direction F 2 .

Sobald der betreffende Anschlag 46 infolge der Drehung der Nockenwalze 38 an der nachlaufenden Kante 34 des Druckereierzeugnisses 12 anschlägt, wird dieses vom Zwischenstapel 16 in Förderrichtung F2 weggestossen und mit der der nachlaufenden Kante 34 gegenüberliegenden vorlaufenden Kante 60 voraus in den Wirkbereich der zweiten Fördereinrichtung 52 gestossen (Fig. 4). Da die Fördergeschwindigkeit v2 der zweiten Fördereinrichtung 52 grösser ist als die Umlaufgeschwindigkeit vU der Anschläge 46, werden die Druckereierzeugnisse 12 von der zweiten Fördereinrichtung 52 aus dem Wirkbereich der Vorsprünge 40 gezogen, so dass eine Verletzung der Druckereierzeugnisse 12 durch diese Vorsprünge 40, selbst bei sehr grosser Drehzahl der Nockenwalze 38, verhindert wird.As soon as the stop 46 in question strikes the trailing edge 34 of the printed product 12 as a result of the rotation of the cam roller 38, the intermediate stack 16 pushes it away in the conveying direction F 2 and with the leading edge 60 opposite the trailing edge 34 into the effective area of the second conveying device 52 pushed (Fig. 4). Since the conveying speed v 2 of the second conveying device 52 is greater than the rotational speed v U of the stops 46, the printed products 12 are pulled by the second conveying device 52 from the effective area of the projections 40, so that the printed products 12 are injured by these projections 40 themselves at a very high speed of the cam roller 38 is prevented.

Nach der Freigabe eines Druckereierzeugnisses 12 durch die Saugeranordnung 18 ist bereits das nachfolgende Paar Saugköpfe 30 zum Erfassen des nächsten Druckereierzeugnisses 12 des Zwischenstapels 16 bereit, wie dies Fig. 4 verdeutlicht. Nach Freigabe eines Druckereierzeugnisses 12 bewegen sich die betreffenden Saugköpfe 30 durch Verschwenken um die betreffende Achse 26 entlang der Bewegungsbahn 58 wieder in die Übernahmestellung zurück. Das Festhalten dieses nächsten, zuoberst auf dem Zwischenstapel 16 liegenden Druckereierzeugnisses 12 durch die Saugköpfe 30 verhindert eine Mitnahme dieses Druckereierzeugnisses 12 durch das vorangehende Druckereierzeugnis. Diese Aufgabe kann auch von einem nicht gezeigten, von den Saugköpfen 30 getrennten Halteelement übernommen werden.After the release of a printed product 12 by the Suction arrangement 18 is already the following pair of suction heads 30 for detecting the next printed product 12 of the intermediate stack 16 is ready, as illustrated in FIG. 4. After releasing a printed product 12 move the relevant suction heads 30 by pivoting about the relevant axis 26 along the movement path 58 back to the takeover position. Holding on this next one, lying on top of the intermediate stack 16 Printed product 12 through the suction heads 30 prevents this printed product 12 from being carried along through the previous printed matter. This task can also from a not shown, from the suction heads 30th separate holding element can be taken over.

Da das Wegstossen der Druckereierzeugnisse 12 ab dem Zwischenstapel 16 durch die in festem Abstand angeordneten Anschläge 46 erfolgt, wird eine äusserst regelmässige Schuppenformation S2 gebildet.Since the pushing away of the printed products 12 from the intermediate stack 16 takes place by the stops 46 arranged at a fixed distance, an extremely regular scale formation S 2 is formed.

Bei den gezeigten Druckereierzeugnissen 12 handelt es sich um gefaltete Druckereiprodukte, wie Zeitschriften, Zeitungen und dergleichen, bzw. Teilen davon, wobei der Falz die Kante 34 bildet, in deren Nachbarschaft die Saugköpfe 30 angreifen. Dadurch ist sichergestellt, dass auch mehrblättrige Druckereierzeugnisse 12 problemlos verarbeitet werden können.The printed products 12 shown are folded printed products such as magazines, newspapers and the like, or parts thereof, the fold the Edge 34 forms, in the vicinity of which the suction heads 30 attack. This ensures that even multi-leaf Printed products 12 processed without problems can be.

Wie den Fig. 1 und 2 entnehmbar ist, ist am in Förderrichtung F2 gesehen hinteren Ende der Stapelstelle 14 eine Düsenanordnung 62 an einem Träger des Maschinengestells 20 angeordnet, die dazu bestimmt ist, einen Luftstrahl zwischen das mittels Saugköpfen 30 angehobene Druckereierzeugnis 12 und den Zwischenstapel 16 einzuleiten, was ein leichtgängiges Wegstossen des Druckereierzeugnisses 12 ab dem Zwischenstapel 16 ermöglicht, selbst wenn die Druckereierzeugnisse 12 die Tendenz haben, aneinander zu haften. As can be seen in FIGS. 1 and 2, a nozzle arrangement 62 is arranged on a support of the machine frame 20 at the rear end of the stacking point 14, as seen in the conveying direction F 2 , which is designed to direct an air jet between the printed product 12 raised by means of suction heads 30 and the Initiate intermediate stack 16, which allows the printed product 12 to be pushed away easily from the intermediate stack 16, even if the printed products 12 have a tendency to adhere to one another.

Eine Mitnahme weiterer Druckereierzeugnisse 12 und Beeinträchtigung des Zwischenstapels 16 wird vermieden.Taking along further printed matter 12 and impairment the intermediate stack 16 is avoided.

Im Anfangsbereich der zweiten Fördereinrichtung 52 wirkt mit dem Bandförderer 54 eine Gewichtsrolle 64 zusammen. Sobald das ab dem Zwischenstapel 16 gestossene Druckereierzeugnis 12 mit der vorlaufenden Kante 60 in den von der Gewichtsrolle 64 und dem Bandförderer 54 gebildeten Spalt einläuft, wird es genau definiert von der zweiten Fördereinrichtung 52 mitgenommen, was ebenfalls zur Bildung der regelmässigen Schuppenformation S2 beiträgt.In the initial area of the second conveyor device 52, a weight roller 64 interacts with the belt conveyor 54. As soon as the printed product 12 pushed from the intermediate stack 16 with the leading edge 60 enters the gap formed by the weight roller 64 and the belt conveyor 54, it is taken along in a precisely defined manner by the second conveyor device 52, which likewise contributes to the formation of the regular scale formation S 2 .

Wie dies insbesondere der Fig. 2 entnehmbar ist, weist die erste Fördereinrichtung 10 einen Bändchenförderer 66 auf. Bei der Stapelstelle 14 sind zwischen den Bändchen 68 und zu diesen wenigstens annähernd parallele stabartige Auflageelemente 70 angeordnet, die in vertikaler Richtung gesehen über die Bändchen 68 vorstehen und in Förderrichtung F1 gesehen in ihrem Anfangsbereich in Richtung gegen unten gebogen sind, um für die der Stapelstelle 14 zugeführten Druckereierzeugnisse 12 eine Rampe zum Aufgleiten auf die Auflageelemente 70 zu bilden. Diese bilden somit eine Auflage für den Zwischenstapel 16 im Wirkbereich der ersten Fördereinrichtung 10.As can be seen in particular in FIG. 2, the first conveyor device 10 has a ribbon conveyor 66. At the stacking point 14 between the ribbons 68 and at least approximately parallel rod-like support elements 70 are arranged, which protrude in the vertical direction over the ribbons 68 and, viewed in the conveying direction F 1 , are bent in their initial region in a downward direction in order for the Stacking point 14 supplied printed products 12 to form a ramp for sliding onto the support elements 70. These thus form a support for the intermediate stack 16 in the effective area of the first conveyor 10.

Mit dem Bändchenförderer 66 wirkt ein frei umlaufendes Andrückband 72 zusammen, um ein sicheres Einschieben der zugeführten Druckereierzeugnisse 12 von unten in den Zwischenstapel 16 sicherzustellen. In Förderrichtung F1 gesehen, ist am Ende der Stapelstelle 16 an Stützelementen 70 ein Anschlag 74 befestigt. Mittels der ersten Fördereinrichtung 10 werden die dem Zwischenstapel 16 zugeführten Druckereierzeugnisse 12 mit der vorlaufenden Kante 60 an diesem Anschlag 74 in Anlage gebracht, wodurch die Bildung eines qualitativ guten Zwischenstapels 16, selbst bei sehr hoher Verarbeitungsgeschwindigkeit, sichergestellt wird. Durch das Aufliegen des Zwischenstapels 16 auf den Auflageelementen 70 wird eine Beschädigung der Druckereierzeugnisse 12 durch die Bändchen 68 sicher verhindert.A free-running pressure belt 72 interacts with the belt conveyor 66 in order to ensure that the printed products 12 supplied are securely inserted into the intermediate stack 16 from below. Seen in the conveying direction F 1 , a stop 74 is fastened to support elements 70 at the end of the stacking point 16. By means of the first conveyor device 10, the printed products 12 fed to the intermediate stack 16 are brought into abutment with this leading edge 60 at this stop 74, thereby ensuring the formation of a good quality intermediate stack 16, even at a very high processing speed. By the intermediate stack 16 resting on the support elements 70, damage to the printed products 12 by the tapes 68 is reliably prevented.

Die erste Fördereinrichtung 10 ist als Wippe ausgebildet, die um die Achse 76' der Umlenkwalze 76 für die Bändchen 68 in Richtung des Doppelpfeiles B schwenkbar ist. Dadurch sind die Auflageelemente 70 heb- und senkbar, um unabhängig von der Höhe des Zwischenstapels 16 zu gewährleisten, dass dessen Oberseite sich immer im wesentlichen auf gleicher Höhe befindet, um ein sicheres Erfassen des jeweils obersten Druckereierzeugnisses 12 durch die Saugköpfe 30 zu gewährleisten. Ein Höhentaster 78 greift die Lage des obersten Druckereierzeugnisses 12 des Zwischenstapels 14 bei der nachlaufenden Kante 34 ab. Durch das Signal dieses Höhentasters 78 wird die Schwenklage der ersten Fördereinrichtung 10 geregelt.The first conveyor 10 is designed as a rocker, around the axis 76 'of the deflection roller 76 for the tapes 68 is pivotable in the direction of the double arrow B. Thereby the support elements 70 can be raised and lowered to be independent to ensure from the height of the intermediate stack 16 that its top is always essentially the same Height to ensure a safe grasp of each uppermost printed product 12 through the suction heads 30 to ensure. A height button 78 picks up the location of the uppermost printed product 12 of the intermediate stack 14 at the trailing edge 34. By the signal of this Height sensor 78 becomes the pivot position of the first conveyor 10 regulated.

Die Auflageelemente 70 und eine unterhalb diesen angeordnete Umlenkwalze 80 für die Bändchen 68 sind an einem Schlitten 81 angeordnet, der in Längsrichtung des Bändchenförderers 66 verschiebbar ist. Zusammen mit dem Schlitten 81 wird auch die zweite Fördereinrichtung 52 verschoben, wodurch eine problemlose Anpassung der Vorrichtung an unterschiedliche Formate zu verarbeitender Druckereierzeugnisse 12 ermöglicht ist. Die nachlaufende Kante 34 der Druckereierzeugnisse 12 im Zwischenstapel 16 und somit die Saugeranordnung 18 und Stossanordnung 36 können unabhängig vom zu verarbeitenden Format der Druckereierzeugnisse 12 an derselben Stelle verbleiben. Die Stellung der Umlenkwalze 80 bei der Verarbeitung der formatgrössten Druckererzeugnisse 12 ist gestrichelt angedeutet und mit 80' bezeichnet. Vorzugsweise bestehen die Bändchen 68 aus einem gummielastischen Material, so dass die Längenänderung infolge des Verschiebens der Umlenkwalze 80 durch diese selber problemlos aufgenommen werden kann.The support elements 70 and one arranged below them Deflection roller 80 for the tapes 68 are on one Carriage 81 arranged in the longitudinal direction of the ribbon conveyor 66 is displaceable. Together with the The second conveyor 52 also becomes a carriage 81 postponed, making it easy to customize the device to be processed in different formats Printed products 12 is enabled. The trailing one Edge 34 of printed products 12 in intermediate stack 16 and thus the suction arrangement 18 and push arrangement 36 can regardless of the format of the printed products to be processed 12 remain in the same place. The Position of the deflection roller 80 when processing the largest format Printer products 12 are indicated by dashed lines and labeled 80 '. Preferably there are Ribbon 68 made of a rubber-elastic material, so that the change in length due to the displacement of the deflecting roller 80 can be easily recorded by them themselves can.

Weiter ist am Bandförderer 54 ein Anschlagelement 82 angeordnet, das bei grösserer Höhe des Zwischenstapels 16 und dadurch verursacht nach unten verschwenkter erster Fördereinrichtung 10 verhindert, dass bei einer allfälligen Störung des Zwischenstapels 16 Druckereierzeugnisse 12 aus diesem herausragen und verklemmt werden könnten. Das Anschlagelement 82 ist mit dem Bandförderer 54 verschiebbar.There is also a stop element 82 on the belt conveyor 54 arranged that at a greater height of the intermediate stack 16th and thereby caused the first to pivot downward Conveyor 10 prevents any Interference of the intermediate stack 16 printed products 12 protrude from this and could be jammed. The Stop element 82 is displaceable with the belt conveyor 54.

Der Vollständigkeit halber sei erwähnt, dass unterhalb der Düsenanordnung 62 ein weiteres Anschlagelement 84 vorgesehen ist, das am Maschinengestell 20 befestigt ist. Es wirkt mit den nachlaufenden Kanten 34 zur Stabilisierung des Zwischenstapels 16 zusammen.For the sake of completeness it should be mentioned that below the A further stop element 84 is provided in the nozzle arrangement 62 is attached to the machine frame 20. It acts with the trailing edges 34 for stabilization of the intermediate stack 16 together.

Es ist denkbar, die Stossanordnung 36 derart auszubilden, dass an einem in sich geschlossenen Zugorgan, beispielsweise einer Kette oder einem Band, die Anschläge 46 bildenden Nocken in festem Abstand angeordnet sind.It is conceivable to design the push arrangement 36 in such a way that that on a self-contained traction element, for example a chain or a band, the stops 46 forming Cams are arranged at a fixed distance.

Es ist auch denkbar, die erste Fördereinrichtung 10 derart anzuordnen, dass in der Fig. 1 gesehen, die Druckereierzeugnisse 12 unterhalb der zweiten Fördereinrichtung 52 von rechts nach links der Stapelstelle 14 zugeführt werden. In diesem Fall wird die in der Schuppenformation S1 vorauslaufende Kante in der Schuppenformation S2 zur nachlaufenden Kante.It is also conceivable to arrange the first conveying device 10 in such a way that, seen in FIG. 1, the printed products 12 are fed to the stacking point 14 below the second conveying device 52 from right to left. In this case, the leading end in the imbricated formation S 1 edge in the imbricated formation S 2 to the trailing edge.

Auch die Saugeranordnung kann zur gezeigten unterschiedlich ausgebildet sein.The suction arrangement can also differ from that shown be trained.
