Description

Die Erfindung betrifft eine Vorrichtung und ein Verfahren zur übergabe von Druckprodukten in einer Rotationsdruckmaschine.The invention relates to a device and a method for transferring printed products in a rotary printing press.

Von den für Rotationsdruckmaschinen verwendeten herkömmlichen Trichterfalzapparaten gibt es zwei Grundtypen, nämlich den Zweitrichter-Falzapparat und den punkturlosen Trichterfalzapparat. In dem Zweitrichter-Falzapparat wird ein Greiferbremszylinder verwendet, welcher die Druckprodukte direkt auf Förderbänder überträgt. In dem punkturlosen Trichterfalzapparat werden Hochgeschwindigkeitsbänder verwendet, die um ungefähr 9% über der Maschinengeschwindigkeit laufen und die Druckprodukte in ein Auslageschaufelrad übertragen, das diese dann auf Förderbänder auslegt. Beide Falzapparattypen sind jedoch aufgrund der in dem Auslagesystem herrschenden Beschränkungen in ihrer Betriebsgeschwindigkeit eingeschränkt. Ferner können Bögen bei der übertragung durch Bänder oft schief zu liegen kommen, wenn es nicht gelingt, die Geschwindigkeiten der inneren und äußeren Bänder genau zu synchronisieren.There are two basic types of conventional former folding machines used for rotary printing presses, namely the two-former folder and the pointless former. A gripper brake cylinder is used in the two-station folder, which transfers the printed products directly to conveyor belts. High-speed belts, which run about 9% above machine speed, are used in the pointless hopper folder and transfer the printed products to a delivery paddle wheel, which then lays them out on conveyor belts. However, both types of folders are limited in their speed of operation due to the limitations in the delivery system. Furthermore, sheets can often skew when being transmitted by tapes if the speeds of the inner and outer tapes cannot be precisely synchronized.

Das U.S. Patent Nr. 1,684,901 betrifft einen Trichterfalzapparat mit durch eine Feder aktivierbaren Falzwalzen, durch welche ein bei hohen Betriebsgeschwindigkeiten auftretender Produktstau beseitigt werden kann. Diese Falzwalzen sind unterhalb eines Falzzylinders befestigt und prägen einen Falz in die Druckprodukte während diese passieren. Die gefalzten Druckprodukte werden in Schaufelradtaschen aufgenommen und können dann auf ein Auslageförderband in geschuppter Form, d.h. eines das andere überlappend, ausgelegt werden.US Pat. No. 1,684,901 relates to a former folder with spring-activated folding rollers, by means of which a product jam occurring at high operating speeds can be eliminated. These folding rollers are attached below a folding cylinder and emboss a fold into the printed products as they pass through. The folded printed products are received in paddle wheel pockets and can then be laid out on a delivery conveyor belt in a scaled form, ie one overlapping the other.

Jedoch müssen bei dieser Anordnung der übertragung der Druckprodukte von dem Falzzylinder in die Schaufelradtaschen diese in der Mitte des Spalts zwischen beiden Falzwalzen eingeführt werden. Bei hohen Produktionsgeschwindigkeiten kann dies einen Stau verursachen.However, with this arrangement of the transfer of the printed products from the folding cylinder into the bucket wheel pockets, these have to be inserted in the middle of the gap between the two folding rollers. This can cause a jam at high production speeds.

DE-A-37 00 930 offenbart ein Verfahren und eine Vorrichtung, entsprechend dem Oberbegriff der Anprüche 1 bzw. 10, zum Stapeln und Positionieren von gefalzten oder ungefalzten Zuschnitten aus Papier, Zellstoff, Vliesstoff oder dergleichen. Einem mit Umfangsnuten versehenen Auslegezylinder ist eine Fächerscheibe zugeordnet. Die an der Fächerscheibe ausgebildeten Schaufelblätter tauchen in die Umfangsnuten am Auslegezylinder ein und entfernen somit das Druckprodukt von dessen Mantelfläche.DE-A-37 00 930 discloses a method and a device according to the preamble of claims 1 and 10, respectively, for stacking and positioning folded or unfolded blanks made of paper, cellulose, nonwoven or the like. A serrated lock washer is assigned to a delivery cylinder provided with circumferential grooves. The airfoils formed on the serrated washer dip into the circumferential grooves on the delivery cylinder and thus remove the printed product from its outer surface.

US 3,459,421 zeigt einen Falzapparat, dessen oberem und unterem produktführenden Zylinder jeweils eine stationär angeordnete, mit einer Ummantelung versehenen Andrückrolle zugeordnet ist. Bei dieser Lösung werden die Falzexemplare über stationär montierte Abstreifer von der Mantelfläche der produktführenden Zylinder in die Schaufelradtaschen geleitet.No. 3,459,421 shows a folder, the upper and lower cylinders of which are assigned a stationary pressure roller provided with a jacket. In this solution, the folded copies are guided from the outer surface of the product-carrying cylinders into the paddle wheel pockets by means of stationary wipers.

Es ist deshalb die Aufgabe der vorliegenden Erfindung, eine direkte Übertragung der Druckprodukte von einem Falzzylinder oder papierführenden Zylinder in Schaufelradtaschen zu ermöglichen, ohne daß dabei Abstreifer, Zwischenwalzen oder Transferbänder verwendet werden.It is therefore the object of the present invention to enable a direct transfer of the printed products from a folding cylinder or paper-guiding cylinder into paddle wheel pockets without the use of scrapers, intermediate rollers or transfer belts.

Eine weitere Aufgabe der vorliegenden Erfindung ist es, das Abbremsen und das Übertragen der Druckprodukte in aufeinanderfolgenden, abgestuften Schritten ohne komplexe Führungsmechanismen zu verbessern.A further object of the present invention is to improve the braking and the transfer of the printed products in successive, graded steps without complex guide mechanisms.

Es ist eine weitere Aufgabe der vorliegenden Erfindung, Mehrfach-Übergabe-Baugruppen vorzusehen, welche es ermöglichen, die Druckprodukte in mehrere verschiedene Auslagebahnen auszulenken.It is another object of the present invention to provide multiple handover assemblies which are enable the printed products to be deflected into several different delivery paths.

Die Aufgabe wird gemäß der Merkmale des Patentanspruches 1 gelöst.The object is achieved according to the features of patent claim 1.

Die an die Umfangsfläche des papierführenden Zylinders angestellte Transporteinrichtung trägt und führt die Druckprodukte beim Eintreten in die Schaufelradtaschen. Die Transporteinrichtung trägt die Druckprodukte auf der einen Seite während der papierführende Zylinder sie auf der anderen Seite trägt. Diese zweiseitige Stütze verhindert, daß die Kanten der Druckprodukte sich spreizen oder öffnen. Außerdem wird dadurch ermöglicht, daß die von der Umfangsfläche des papierführenden Zylinders genommenen Druckprodukte bei deren Verlangsamung vollständig in die entsprechenden Schaufelradtaschen eintreten. Die druckausübende Einrichtung, wodurch die Transporteinrichtung verstellbar an die Umfangsfläche des papierführenden Zylinders angestellt wird, hat den Vorteil, daß die Transporteinrichtung genau auf die Dicke des zu bearbeitenden Druckprodukts eingestellt werden kann.The transport device attached to the peripheral surface of the paper-guiding cylinder carries and guides the printed products as they enter the paddle wheel pockets. The transport device carries the printed products on one side while the paper-guiding cylinder carries them on the other side. This two-sided support prevents the edges of the printed products from spreading or opening. It also enables the printed products taken from the peripheral surface of the paper-guiding cylinder to completely enter the corresponding paddle-wheel pockets when they slow down. The pressure-exerting device, as a result of which the transport device is adjustably positioned on the peripheral surface of the paper-guiding cylinder, has the advantage that the transport device can be adjusted precisely to the thickness of the printed product to be processed.

Die vorliegende Erfindung sieht ferner vor, daß die Schaufelblätter mit Schaufelblattspitzen versehen sind, welche in sich entlang der Umfangsfläche des papierführenden Zylinders erstreckende Rillen hineinragen. Auf diese Weise kann der Abstand zwischen den Schaufelradscheiben und dem papierführenden Zylinder sehr klein gehalten werden. Somit sieht die vorliegende Erfindung vor, daß die Hüllkurven der Schaufelradscheiben, d. h. die von den Spitzen der Schaufelblätter geformten gedachten Kurven sich mit der von dem Umfang des jeweiligen papierführenden Zylinders gebildeten Hüllkurve überschneiden. Dies verbessert die operative Zuverlässigkeit während des Transfers von Druckprodukten von der Umfangsfläche des papierführenden Zylinders beträchtlich und reduziert gleichzeitig den von dem Apparat eingenommenen Bauraum.The present invention further provides that the airfoils are provided with airfoil tips which protrude into grooves extending along the peripheral surface of the paper-guiding cylinder. In this way, the distance between the paddle wheel disks and the paper-carrying cylinder can be kept very small. The present invention thus provides that the envelope curves of the bucket wheel disks, ie the imaginary curves formed by the tips of the bucket blades, overlap with the envelope curve formed by the circumference of the respective paper-guiding cylinder. This improves operational reliability during the transfer of print products from the peripheral surface of the paper feed Cylinder considerably and at the same time reduces the installation space occupied by the apparatus.

Die vorliegende Erfindung sieht ferner ein Auslagesystem vor, die mindestens ein Schaufelrad und einem papierführenden Zylinder zugeordnete Auslageförderbänder umfaßt. Diese Ausführung hat den Vorteil, daß bestimmte Druckprodukte auf eine weitere Bearbeitungsbahn gelenkt werden können.The present invention further provides a delivery system which comprises at least one paddle wheel and delivery conveyor belts associated with a paper-guiding cylinder. This design has the advantage that certain printed products can be directed onto a further processing path.

Schließlich sieht die vorliegende Erfindung ein Transportbandsystem vor, das mit Auslenkern ausgestattet ist, welche die Druckprodukte zu mehreren papierführenden Zylindern leiten können. Diese Ausführung hat den Vorteil, daß die Druckprodukte über ein einziges Förderbandsystem in mehrere Auslagemodule, die auch untereinander angeordnet sein können, befördert werden. Es ist also eine parallel transportierte Mehrweg-Auslage von Druckprodukten möglich.Finally, the present invention provides a conveyor belt system which is equipped with deflectors which can direct the printed products to a plurality of paper-guiding cylinders. This embodiment has the advantage that the printed products are conveyed via a single conveyor belt system into several delivery modules, which can also be arranged one below the other. A reusable delivery of printed products transported in parallel is therefore possible.

Die vorliegende Erfindung betrifft ebenso ein Verfahren zur übergabe von Druckprodukten in einer Rotationsdruckmachine, welches die folgenden Schritte umfaßt:

  • das Transportieren von Druckprodukten zu mindestens einem papierführenden Zylinder mit mindestens einem Element zum Ergreifen der darauf liegenden Druckprodukte,
  • das Entfernen der Druckprodukte direkt von der Oberfläche des papierführenden Zylinder durch eine Anzahl Schaufelblätter mindestens eines, dem papierführenden Zylinder zugeordneten Schaufelrades, welches mehrere Schaufelradscheiben mit einer Anzahl Schaufelblätter aufweist,
  • das Leiten der Druckprodukte in zwischen aneinandergrenzenden Schaufelblättern gebildeten Schaufelradtaschen und
  • das Abstützen der Druckprodukte während deren übergabe von dem papierführenden Zylinder in das Schaufelrad mittels einer Vorrichtung, die über einen druckausübenden Mechanismus mit einer Andrückkraft an einen papierführenden Zylinder stellbar ist.
The present invention also relates to a method for transferring printed products in a rotary printing press, which comprises the following steps:
  • the transport of printed products to at least one paper-carrying cylinder with at least one element for gripping the printed products lying thereon,
  • the removal of the printed products directly from the surface of the paper-guiding cylinder by means of a number of airfoils of at least one impeller assigned to the paper-guiding cylinder, which has a plurality of impeller disks with a number of airfoils,
  • directing the printed products into vane wheel pockets formed between adjacent airfoils and
  • the support of the printed products during their transfer from the paper-carrying cylinder into the paddle wheel by means of a device which can be set by means of a pressure-exerting mechanism with a pressing force on a paper-carrying cylinder.

In Fig. 1 ist eine bevorzugte Ausführung der vorliegenden Erfindung gezeigt. Ein Förderbandsystem 1 transportiert Druckprodukte 2 zu einem papierführenden Zylinder 3. Eine Vorrichtung zum Ergreifen der Druckprodukte 2, die mehrere, an dem Umfang des papierführenden Zylinders 3 angeordnete Greiferbrücken 4 aufweist, nimmt die Druckprodukte 2 auf. Wie in Fig. 2 besser zu sehen ist, aktiviert ein das Ergreifen und Loslassen der Druckprodukte 2 steuerndes Element die Greifervorrichtung. Vorzugsweise nehmen die durch einen Anlenkarm 5 aktivierten Greiferbrücken 4 eine Rolle 6 auf, die in einer Kurve 7 umläuft. Auf dem Umfang des papierführenden Zylinders 3 angeordnete Führungsbürsten 8 führen die Druckprodukte 2 und verhindern, daß diese sich ablösen, besonders bei hohen Produktionsgeschwindigkeiten.1 shows a preferred embodiment of the present invention. A conveyor belt system 1 transports printed products 2 to a paper-carrying cylinder 3. A device for gripping the printed products 2, which has a plurality of gripper bridges 4 arranged on the circumference of the paper-carrying cylinder 3, receives the printed products 2. As can be seen better in FIG. 2, an element controlling the gripping and releasing of the printed products 2 activates the gripper device. The gripper bridges 4 activated by a link arm 5 preferably take up a roller 6 which rotates in a curve 7. Guide brushes 8 arranged on the circumference of the paper-guiding cylinder 3 guide the printed products 2 and prevent them from coming off, especially at high production speeds.

Eine Einrichtung zum Transportieren der Druckprodukte 2, vorzugsweise auf einer Welle 16a angebrachte Transportrollen 10, übergeben die Druckprodukte 2 von dem papierführenden Zylinder 3 an ein Schaufelrad 9 mit einer Anzahl an einer Welle 24 befestigten Schaufelradscheiben 9a, wie in Fig. 2 gezeigt. Eine druckausübende Vorrichtung mit einem Hebelmechanismus 11 stellt die Transportrollen 10 an die Umfangsfläche des papierführenden Zylinders 3 an, wie in Fig. 1 gezeigt. Der Hebelmechanismus 11 übt entsprechend der Dicke der bearbeiteten Druckprodukte Druck auf die Transport rollen 10 aus. Ferner kann der Hebelmechanismus 11 die Transportrollen 10 vollständig von der Umfangsfläche des papierführenden Zylinders 3 abstellen, z. B. beim Beheben eines Produktstaus, sollte er vorkommen.A device for transporting the printed products 2, preferably transport rollers 10 mounted on a shaft 16a, transfers the printed products 2 from the paper-guiding cylinder 3 to a paddle wheel 9 with a number of paddle wheel disks 9a attached to a shaft 24, as shown in FIG. 2. A pressure-exerting device with a lever mechanism 11 places the transport rollers 10 on the peripheral surface of the paper-guiding cylinder 3, as shown in FIG. 1. The lever mechanism 11 exerts pressure on the transport rollers 10 in accordance with the thickness of the processed printed products. Furthermore, the lever mechanism 11 can completely turn off the transport rollers 10 from the peripheral surface of the paper-guiding cylinder 3, e.g. B. when clearing a product jam, it should occur.

Nachdem die Druckprodukte 2 den Bereich, wo die Transportrollen 10 die Umfangsfläche des papierführenden Zylinders 3 kontaktieren, passiert haben, nehmen die Schaufelblätter 12 der Schaufelradscheiben 9a die Vorderkanten der Druckprodukte 2 auf. Die Schaufelblattspitzen 12a der Schaufelblätter tauchen in Ausnehmungen 3a ein, welche sich entlang der Umfangsfläche des papierführenden Zylinders 3 erstrecken, wie in Fig. 2 gezeigt. Die Hüllkurve 34 des Schaufelrads 9 und der Umfang des papierführenden Zylinders 3 überschneiden sich. Die Vorderkanten der Druckprodukte 2 werden von Greifern 4a gehalten, und die Schaufelblattspitzen 12a bewegen sich in den Raum zwischen die auf der Greiferbrücke 4 angebrachten einzelnen Greifer 4a hinein und führen so die Vorderkanten der Druckprodukte 2.After the printed products 2 have passed the area where the transport rollers 10 contact the peripheral surface of the paper-guiding cylinder 3, the airfoils 12 of the impeller disks 9a take up the front edges of the printed products 2. The airfoil tips 12a of the airfoil plunge into recesses 3a which extend along the circumferential surface of the paper-guiding cylinder 3, as shown in FIG. 2. The envelope curve 34 of the paddle wheel 9 and the circumference of the paper-guiding cylinder 3 overlap. The front edges of the printed products 2 are held by grippers 4a, and the airfoil tips 12a move into the space between the individual grippers 4a attached to the gripper bridge 4 and thus guide the front edges of the printed products 2.

Die Transportrollen 10 bewirken die vollständige übergabe der Druckprodukte 2 in die zwischen den aneinandergrenzenden Schaufelblättern 12 gebildeten Schaufelradtaschen 13 in dem Schaufelrad 9. Während dieser übergabe tragen die Transportrollen 10 die Druckprodukte 2 auf der einen Seite und die Umfangsfläche des papierführenden Zylinders 3 trägt sie auf der anderen Seite. Diese zweiseitige Stütze verhindert, daß die Kanten der Druckprodukte 2 sich spreizen oder sich öffnen, und durch den von dem Hebelmechanismus 11 auf die Transportrollen 10 ausgeübten Druck werden die Druckprodukte 2 zusammengedrückt und die darin eingeschlossene Luft kann entweichen. Die Druckprodukte 2 werden also während der Dauer ihrer übergabe vollständig gestützt.The transport rollers 10 bring about the complete transfer of the printed products 2 into the paddle wheel pockets 13 formed between the adjacent blades 12 in the paddle wheel 9. During this transfer, the transport rollers 10 carry the printed products 2 on one side and the peripheral surface of the paper-carrying cylinder 3 carries them on the other side. This two-sided support prevents the edges of the printed products 2 from spreading or open, and by the pressure exerted by the lever mechanism 11 on the transport rollers 10, the printed products 2 are compressed and the air enclosed therein can escape. The printed products 2 are therefore fully supported for the duration of their transfer.

Die von den Schaufelblättern 12 geführten Druckprodukte 2 werden vollständig in die Schaufelradtaschen 13 eingefügt. Dies wird während der Drehbewegung des jeweiligen papierführenden Zylinders 3 und des jeweiligen Schaufelrads 9 von den Transportrollen 10 ausgeführt. Je nach Produktgröße, -dicke und -qualität können wechselweise Schaufelradtaschen 13 leer bleiben, z.B. während des Produktionsvorgangs "sammeln". Nachdem die Druckprodukte 2 vollständig in die Schaufelradtaschen 13 eingefügt wurden, werden sie in geschuppter Form über Förderbänder weiteren Bearbeitungseinheiten zugeleitet.The printed products 2 guided by the airfoils 12 are completely inserted into the airbag pockets 13. This is carried out by the transport rollers 10 during the rotational movement of the respective paper-guiding cylinder 3 and the respective paddle wheel 9. Depending on the product size, thickness and quality, paddle wheel bags 13 can alternately remain empty, e.g. "collect" during the production process. After the printed products 2 have been completely inserted into the paddle wheel pockets 13, they are fed in a scaled form via conveyor belts to further processing units.

Fig. 2 zeigt eine Draufsicht der bevorzugten Ausführung der vorliegenden Erfindung. Der papierführende Zylinder 3 ist auf einer Welle 14 angebracht, die in Seitenwänden 15 und 15a gelagert ist. Der papierführende Zylinder 3 wird über eine Riemenscheibe 16 angetrieben. An der linken Seitenwand 15 bestimmt die Kurve 7, in welcher die Rolle 6 umläuft, den Zeittakt des öffnens und Schließens der Greifer 4a auf der Greiferbrücke 4.Figure 2 shows a top view of the preferred embodiment of the present invention. The paper-guiding cylinder 3 is mounted on a shaft 14 which is mounted in side walls 15 and 15a. The paper-guiding cylinder 3 is driven by a pulley 16. On the left side wall 15, the curve 7, in which the roller 6 rotates, determines the timing of the opening and closing of the grippers 4a on the gripper bridge 4.

Die Transportrollen 10 sind auf der Welle 16a unterhalb des papierführenden Zylinders 3 nebeneinander angeordnet. Die Welle 16a ist mittels einer drehfesten, flexiblen Kupplung 17 an eine Antriebswelle 18 gekoppelt. Die Antriebswelle 18 ist auf zwei Lagern 19, 20 in der Seitenwand 15 gelagert und wird über eine Riemenscheibe 21 angetrieben.The transport rollers 10 are arranged side by side on the shaft 16a below the paper-guiding cylinder 3. The shaft 16a is coupled to a drive shaft 18 by means of a rotationally fixed, flexible coupling 17. The drive shaft 18 is mounted on two bearings 19, 20 in the side wall 15 and is driven by a pulley 21.

Der Hebelmechanismus 11 reguliert den auf die Transportrollen 10 ausgeübten Druck. Mit Hilfe der Arme 22 und der Achse 23 kann die Welle 16a verstellt werden. Die Transportrollen 10 rotieren zwischen den einzelnen Schaufelradscheiben 9a. Dies erlaubt eine Verstellung der Transportrollen 10 entsprechend der Produktbreite. Die Welle 24 wird durch eine Riemenscheibe 25 angetrieben, die einen wesentlich größeren Durchmesser als die Riemenscheiben 16 und 21 hat.The lever mechanism 11 regulates the pressure exerted on the transport rollers 10. With the help of the arms 22 and the axis 23, the shaft 16a can be adjusted. The transport rollers 10 rotate between the individual paddle wheel disks 9a. This allows the transport rollers 10 to be adjusted according to the product width. The shaft 24 is driven by a pulley 25, which has a much larger diameter than the pulleys 16 and 21.

Der Hebelmechanismus 11 umfaßt einen Stellzylinder 26, womit die Position und und der Anpassungsdruck der Transportrollen 10 eingestellt werden können, wie in Fig. 1 gezeigt. Fig. 2 zeigt wie die Schaufelblattspitzen 12a der Schaufelblätter 12 in die Ausnehmungen 3a in der Außenfläche der papierführenden Zylinder 3 eintauchen ohne diese zu berühren. Durch diese Konfiguration wird Bauraum gespart und die Betriebszuverlässigkeit bei der übergabe der Druckprodukte gesteigert. Außerdem bilden die Ausnehmungen 3a ein Luftkissen unter den von den Greifern 4a ergriffenen Druckprodukten 2. Damit wird das Entfernen der Druckprodukte 2 von der Oberfläche des papierführenden Zylinders 3 erleichtert.The lever mechanism 11 comprises an actuating cylinder 26, by means of which the position and the adjustment pressure of the transport rollers 10 can be adjusted, as shown in FIG. 1. Fig. 2 shows how the blade tips 12a of the blades 12 dip into the recesses 3a in the outer surface of the paper-carrying cylinders 3 without touching them. This configuration saves installation space and increases operational reliability when transferring the printed products. In addition, the recesses 3a form an air cushion under the printed products 2 gripped by the grippers 4a. This makes it easier to remove the printed products 2 from the surface of the paper-carrying cylinder 3.

In Fig. 3 ist eine Modifikation der bevorzugten Ausführungsform der vorliegenden Erfindung gezeigt. Es sind mehrere Auslagemodule untereinander angeordnet. In dieser Anordnung können mehrere verschiedenartige Druckprodukte 2 ausgelegt werden. Die Druckprodukte 2 werden geschnitten und durch das Förderbandsystem 1 zu einem von drei papierführenden Zylindern 27, 28 oder 29 transportiert. Die papierführenden Zylinder 27, 28 und 29 können auf unterschiedliche Arbeitsweisen eingestellt werden. Bei dieser Anordnung sind die Greiferbrücken 4 des obersten papierführenden Zylinders 27 so eingestellt, daß diese jedes dritte Druckprodukt 2 aus dem Produktstrom ergreifen. Die darunter angeordneten papierführenden Zylinder 28 und 29 können so getaktet sein, daß jeweils jedes zweite und dritte Druckprodukt 2 dem Produktstrom entnommen und in die nachgeordneten Schaufelräder 9 geführt und schließlich auf Auslagebändern 33 abgelegt werden können.Figure 3 shows a modification of the preferred embodiment of the present invention. Several delivery modules are arranged one below the other. In this arrangement, several different types of printed products 2 can be designed. The printed products 2 are cut and transported through the conveyor belt system 1 to one of three paper-guiding cylinders 27, 28 or 29. The paper-guiding cylinders 27, 28 and 29 can be set to different working methods. In this arrangement, the gripper bridges 4 of the uppermost paper-guiding cylinder 27 are set so that they grab every third printed product 2 from the product stream. The underneath arranged paper-guiding cylinders 28 and 29 can be clocked so that every second and third printed product 2 can be removed from the product stream and fed into the downstream paddle wheels 9 and finally placed on delivery belts 33.

Diese Modifikation der bevorzugten Ausführung der vorliegenden Erfindung sieht auch vor, daß alle Druckprodukte 2 auch zu dem oberen, sechs Greiferbrücken aufweisenden papierführenden Zylinder 27 abgeleitet werden können. In diesem Fall würden die unteren Auslagemodule 31, 32 von dem Antriebsstrang abgekoppelt werden.This modification of the preferred embodiment of the present invention also provides that all printed products 2 can also be diverted to the upper, paper-guiding cylinder 27, which has six gripper bridges. In this case, the lower delivery modules 31, 32 would be decoupled from the drive train.

Die Zuleitung bestimmter Druckprodukte 2 an ein bestimmtes der Auslagemodule 30, 31 und 32 kann via im Förderbandsystem 1 vorgesehene Weichen 1A und 1B vorgenommen werden. Dadurch sind mehrere, den Produktionserfordernissen gerecht werdende Produktionsarten möglich. Wie bereits oben erwähnt, sind den papierführenden Zylindern 27, 28 und 29 Transportrollen 10 zugeordnet, welche die Druckprodukte 2 stützen bis diese vollständig in den Schaufelradtaschen 13 aufgenommen sind.The supply of certain printed products 2 to a specific one of the delivery modules 30, 31 and 32 can be carried out via switches 1A and 1B provided in the conveyor belt system 1. This enables several types of production that meet the production requirements. As already mentioned above, the paper-guiding cylinders 27, 28 and 29 are assigned transport rollers 10 which support the printed products 2 until they are completely accommodated in the paddle wheel pockets 13.

Wie in dieser Anordnung gezeigt, umfaßt jedes der Auslagemodule 30, 31 und 32 einen papierführenden Zylinder 27, 28 und 29, Transportrollen 10, Schaufelräder 9 und Auslagebänder 33. Falls ein Falzapparat bisher nur auf zwei Produktionsarten beschränkt war, kann diese Kapazität leicht durch ein zusätzliches Auslagemodul erweitert werden. In diesem Fall muß das Förderbandsystem 1 entsprechend verlängert und die erforderliche Anzahl zusätzlicher Auslagemodule installiert werden.As shown in this arrangement, each of the delivery modules 30, 31 and 32 comprises a paper-carrying cylinder 27, 28 and 29, transport rollers 10, paddle wheels 9 and delivery belts 33. If a folder has hitherto been limited to only two types of production, this capacity can easily be increased by one additional delivery module can be expanded. In this case, the conveyor belt system 1 must be extended accordingly and the required number of additional delivery modules installed.

Fig. 4 zeigt ein dem papierführenden Zylinder 3 zugeordnetes Schaufelrad. Wie bereits in Fig. 1 dargestellt, ist deutlich die überlappung der Hüllkurve 34 mit der Umfangsfläche des papierführenden Zylinders 3 zu erkennen. Ebenfalls gezeigt ist das Eintauchen der Schaufelblattspitzen 12a in die Ausnehmungen 3a, die sich entlang der Umfangsfläche des papierführenden Zylinders 3 erstrecken. Durch den Kontakt der Schaufelblattspitzen 12a mit den Vorderkanten der Druckprodukte 2 werden diese von der Oberfläche des papierführenden Zylinders 3 entfernt und in die entsprechenden Schaufelradtaschen 13 geführt, wobei die Druckprodukte 2 abgebremst werden.4 shows an impeller assigned to the paper-guiding cylinder 3. As already shown in FIG. 1, the overlap of the envelope 34 with the circumferential surface of the to recognize paper-carrying cylinder 3. Also shown is the immersion of the airfoil tips 12a in the recesses 3a, which extend along the circumferential surface of the paper-guiding cylinder 3. Due to the contact of the blade tips 12a with the front edges of the printed products 2, these are removed from the surface of the paper-guiding cylinder 3 and guided into the corresponding paddle wheel pockets 13, the printed products 2 being braked.

Fig. 5 zeigt eine Einrichtung zum Ergreifen der Druckprodukte 2 auf einem papierführenden Zylinder 35, und die Fig. 5a, 5b, 5c, 5d und 5e zeigen die verschiedenen Stadien des Einlaufs eines Druckprodukts 2 in eine Schaufelradtasche 13. Der als Falzklappenzylinder in einem Falzapparat ausgebildete papierführende Zylinder 35 weist an seinem Umfang mehrere Falzklappen 37 auf. Diese Falzklappen 37 arbeiten mit beweglichen Falzklappen 36 zusammen. Die beweglichen Falzklappen 36 werden von dem bereits erwähnten Kurvenrollenmechanismus 5, 6 und 7 gesteuert. In diesem Ausführungsbeispiel ist die Drehrichtung des papierführenden Zylinders 35 und des zugeordneten Schaufelrads 9 der Drehrichtung des in den Fig. 1 bis 4 gezeigten papierführenden Zylinders und des Schaufelrads entgegengesetzt.5 shows a device for gripping the printed products 2 on a paper-guiding cylinder 35, and FIGS. 5a, 5b, 5c, 5d and 5e show the different stages of the entry of a printed product 2 into a paddle wheel pocket 13. The one as a folding jaw cylinder in a folder trained paper-guiding cylinder 35 has a plurality of folding flaps 37 on its circumference. These jaws 37 cooperate with movable jaws 36. The movable jaws 36 are controlled by the cam roller mechanisms 5, 6 and 7 already mentioned. In this exemplary embodiment, the direction of rotation of the paper-guiding cylinder 35 and the associated paddle wheel 9 is opposite to the direction of rotation of the paper-guiding cylinder and the paddle wheel shown in FIGS. 1 to 4.

Fig. 5a zeigt ein von der beweglichen Falzklappe 36 und der Falzklappe 37 des papierführenden Zylinders 35 ergriffenes Druckprodukt 2. Es wird der Moment gezeigt, in dem die bewegliche Falzklappe 36 das Druckprodukt 2 freigibt. Die Schaufelblattspitze 12a bewegt sich unter die Vorderkante des Druckprodukts 2 und führt somit das vordere Teil des Druckprodukts in die Schaufelradtasche 13 ein. Die übergabe und das Stützen der Druckprodukte 2 erfolgt durch die Transportrollen 10, deren auf die Oberfläche des papierführenden Zylinders 35 ausgeübter Druck reguliert wird.5a shows a printed product 2 gripped by the movable folding flap 36 and the folding flap 37 of the paper-guiding cylinder 35. The moment in which the movable folding flap 36 releases the printed product 2 is shown. The airfoil tip 12a moves under the front edge of the printed product 2 and thus introduces the front part of the printed product into the impeller wheel pocket 13. The transfer and support of the printed products 2 is carried out by the transport rollers 10, the pressure exerted on the surface of the paper-guiding cylinder 35 being regulated.

Wie oben bereits beschrieben, überlappt sich die Hüllkurve 34 mit dem Umfang des papierführenden Zylinders 35.As already described above, the envelope curve 34 overlaps the circumference of the paper-guiding cylinder 35.

Fig. 5b und 5c zeigen weitere Stadien des Druckprodukteinlaufs 2 in die Schaufelradtasche 13. Fig. 5c zeigt den Moment, wenn der Einlauf des Druckprodukts 2 in die Schaufelradtasche 13 via Transportrollen 10 vollendet ist.5b and 5c show further stages of the printed product inlet 2 into the bucket wheel pocket 13. FIG. 5c shows the moment when the entry of the printed product 2 into the bucket wheel pocket 13 via transport rollers 10 is completed.

Fig. 5d zeigt das Druckprodukt 2 bei seiner Bewegung zur Außenkante des Schaufelblattes 12. Fig. 5e zeigt das Druckprodukt 2 gerade vor dem Erreichen des Bodens der Schaufelradtasche 13. Mit dem weiteren Einlauf des Druckprodukts 2 in die Schaufelradtasche 13 wird der Abstand a kleiner und kleiner und somit verhindert, daß die Kanten des Druckprodukts 2 sich spreizen oder öffnen.Fig. 5d shows the printed product 2 as it moves to the outer edge of the airfoil 12. Fig. 5e shows the printed product 2 just before reaching the bottom of the bucket wheel pocket 13. With the further entry of the printed product 2 into the bucket wheel pocket 13, the distance a becomes smaller and smaller and thus prevents the edges of the printed product 2 from spreading or opening.
