Description

Die Erfindung betrifft eine Vorrichtung zum Fördern von Bogen oder Bogenpaketen nach dem Oberbegriff des Anspruchs 1. Eine derartige Vorrichtung ist aus der DE-OS 3100866 bekannt. Nachteilig ist es, dass hier lediglich der obere Teller beim Vorbeilaufen an einer Steuerschiene um einen von der Schrägstellung derselben abhängigen Betrag gedreht werden kann. Eine Nachregelung des Drehwinkels ist nicht möglich, was erforderlich sein kann, wenn z.B. die Bogen schräg angeliefert werden. Eine derartige Vorrichtung ist auch im Prinzip aus der CH-PS 546 197 bekannt. Eine ähnliche Vorrichtung ist aus der DE-AS 1 586 347 bekannt. Mit dieser können flache Gegenstände, wie Schläuche, zur Herstellung von Säcken oder Beuteln aus der Längslage in die Querlage gedreht werden. Dabei wird der Antrieb für die Drehvorrichtungsteile von dem Fortbewegungsantrieb über Drehzapfen abgeleitet und mittels einer von einer ortsfesten Kurvenbahn gesteuerten Kurbel gesteuert. Diese Vorrichtung baut ebenfalls voluminös und ist dementsprechend teuer. Nachteilig ist es hier auch, dass eine exakte Einstellung und insbesondere eine Nachregelung des Drehwinkels nicht möglich ist, der sich z. B. durch Abnutzungserscheinungen an der Kurve im Laufe der Zeit verändert.The invention relates to a device for conveying sheets or sheet packages according to the preamble of claim 1. Such a device is known from DE-OS 3100866. It is disadvantageous that here only the upper plate can be rotated by an amount dependent on the inclined position as it passes a control rail. It is not possible to readjust the angle of rotation, which may be necessary if e.g. the sheets are delivered at an angle. Such a device is also known in principle from CH-PS 546 197. A similar device is known from DE-AS 1 586 347. This can be used to turn flat objects, such as hoses, from the longitudinal position into the transverse position for the production of sacks or bags. The drive for the rotating device parts is derived from the locomotive drive via pivot pins and controlled by means of a crank controlled by a stationary cam track.

Bekanntlich wird bei Bahnen bedruckenden Rotationsdruckmaschinen nach dem letzten Druckwerk die Druckträgerbahn zwecks Erzeugung des ersten Längsfalzes über Falztrichter gezogen und anschliessend quergeschnitten. Der erste Querfalz wird dann in dem Falzapparat üblicherweise unter Zuhilfenahme eines Falzklappenzylinders erzeugt, wonach bedarfsweise der dritte Falz mittels eines sog. Schwertfalzwerkes erzeugt wird. Für diesen dritten Falz ist es erforderlich, zu falzende Exemplare abzubremsen, was besonders bei mit hohen Durchsatzgeschwindigkeiten arbeitenden Maschinen problematisch ist und Grenzen für die maximale Bearbeitungsgeschwindigkeit setzt.As is known, in the case of web-printing rotary printing machines, the print carrier web is drawn over the former for the purpose of producing the first longitudinal fold and then cross-cut. The first transverse fold is then usually produced in the folding apparatus with the aid of a folding jaw cylinder, after which the third fold is produced as required by means of a so-called sword folding mechanism. For this third fold, it is necessary to slow down copies to be folded, which is particularly problematic for machines working at high throughput speeds and places limits on the maximum processing speed.

Aufgabe der Erfindung ist es, eine kompaktbauende Fördervorrichtung zum Transportieren von Bogen oder Bogenpaketen vorzugsweise von gefalzten bzw. zu falzenden Exemplaren aufzuzeigen, mit der eine gezielte individuelle Drehung der Bogen bei voller Transportgeschwindigkeit möglich ist, so dass auch der dritte Falz bzw. der zweite Längsfalz mit rotierenden Mitteln, wie beispielsweise einem weiteren Falzklappenzylinder, bei voller Geschwindigkeit erzeugt werden kann, wobei eine zeitgerechte Erfassung und Freigabe der Bogen oder Bogenpakete und automatisch, d.h. ohne die Betätigung von Steuermitteln, erfolgen soll und ausserdem eine exakte Einstellung und Nachregelung des Drehwinkels möglich ist. Diese Aufgabe wird durch die Anwendung der im Kennzeichen des Anspruches 1 angegebenen Merkmale gelöst. Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen und der Beschreibung in Verbindung mit den Zeichnungen.The object of the invention is to provide a compact conveyor device for transporting sheets or packages of sheets, preferably of folded or to be folded copies, with which a targeted individual rotation of the sheets at full transport speed is possible, so that the third fold or the second longitudinal fold with rotating means, such as another folding jaw cylinder, can be generated at full speed, with timely detection and release of the sheets or sheet packages and automatically, ie without the use of control means, and also an exact adjustment and readjustment of the angle of rotation is possible. This object is achieved by using the features specified in the characterizing part of claim 1. Further developments of the invention result from the subclaims and the description in conjunction with the drawings.

Aus den DE-PS 830 344 und 919711 sind zwar bereits Umlenkeinrichtungen für bogenförmige Falzprodukte bekannt, bei denen unter Einsatz von schräggestellten Transportmitteln, wie Förderbändern, eine Richtungsänderung der zu transportierenden Produkte möglich ist, jedoch ist mit einer derartigen Umlenkung stets eine Abbremsung verbunden und ausserdem ist eine Drehung der Produkte in der Weise nicht möglich, dass die vorauslaufenden Kanten der Produkte wahlweise verändert werden können.From DE-PS 830 344 and 919711, deflection devices for curved folding products are already known, in which a change of direction of the products to be transported is possible using inclined transport means, such as conveyor belts, however, such a deflection always involves braking and moreover the products cannot be rotated in such a way that the leading edges of the products can optionally be changed.

Im folgenden wird die Erfindung anhand eines Ausführungsbeispieles im einzelnen erläutert, wobei Bezug auf die beiliegenden Zeichnungen genommen wird. In diesen zeigen:

  • Fig. 1 eine Seitenansicht der erfindungsgemässen Förder- und Drehvorrichtung,
  • Fig. 2 eine Draufsicht auf die Vorrichtung gemäss Fig. 1 und
  • Fig. 3 einen Schnitt durch die Linie 111-111 der Fig. 1.
In the following the invention is explained in detail using an exemplary embodiment, reference being made to the accompanying drawings. In these show:
  • 1 is a side view of the conveyor and rotating device according to the invention,
  • Fig. 2 is a plan view of the device according to Fig. 1 and
  • 3 shows a section through line 111-111 of FIG. 1.

Die in den Figuren 1 bis 3 dargestellte Fördervorrichtung eignet sich vorzugsweise in einer einer Rotationsdruckmaschine nachgeordneten Falzeinrichtung. Dabei kann die Fördervorrichtung an einen allgemein bekannten Falzklappenzylinder 1 angebaut werden, in dem in üblicher Weise der erste Querfalz erzeugt wurde. Wie bereits erwähnt, wird bekanntlich zuvor der erste Längsfalz durch dem Falzklappenzylinder 1 vorgeschaltete (nicht gezeigte) Falztrichter erzeugt. Um den Falzklappenzylinder 1 geführte Bandleitungen 2 übernehmen die zu transportierenden Falzprodukte, beispielsweise Bogenpakete oder Bogen 3, mit voller Maschinengeschwindigkeit.The conveyor device shown in FIGS. 1 to 3 is preferably suitable in a folding device arranged downstream of a rotary printing press. The conveyor device can be attached to a generally known folding jaw cylinder 1, in which the first transverse fold was produced in the usual way. As already mentioned, it is known that the first longitudinal fold is generated beforehand by the former (not shown) by the former cylinder 1. Band lines 2 guided around the folding jaw cylinder 1 take over the folding products to be transported, for example sheet packs or sheets 3, at full machine speed.

Wie Fig. 1 am besten erkennen lässt, gelangen die Bogen zwischen zwei Teile 4, 5, von denen im Nachfolgenden der Teller 4 als oberer Teller und der Teller 5 als unterer Teller bezeichnet wird. Beim Einlaufen der Bogen 3 zwischen die Teller 4, 5 weisen diese einen bestimmten Abstand auf. Befindet sich der Bogen 3 in der gewünschten Lage zwischen den Tellern 4, 5, so wird in einer noch zu beschreibenden Weise sichergestellt, dass die Teller 4, 5 zusammenfahren und den Bogen 3 festklemmen. In Fig. 1 sind drei derartige Tellerpaare entlang des Förderweges dargestellt, die mit 4, 5; 4', 5' und 4", 5" bezeichnet sind. Fig. 2 lässt erkennen, dass insgesamt sechs derartige Tellerpaare eingesetzt werden können, von denen jeweils drei in Aktion entlang des Förderweges sind und drei sich auf dem Rückweg einer ovalen Bahn befinden.As can best be seen in FIG. 1, the arches pass between two parts 4, 5, of which the plate 4 is referred to below as the upper plate and the plate 5 as the lower plate. When the sheets 3 run in between the plates 4, 5, they are at a certain distance. If the sheet 3 is in the desired position between the plates 4, 5, it is ensured in a manner to be described below that the plates 4, 5 move together and clamp the sheet 3. In Fig. 1, three such plate pairs are shown along the conveyor path, which with 4, 5; 4 ', 5' and 4 ", 5". Fig. 2 shows that a total of six such plate pairs can be used, three of which are in action along the conveyor path and three are on the way back of an oval path.

Mit Hilfe dieser Teller 4, 5 kann der Bogen um einen bestimmten Winkelbetrag, hier um exakt 90° gedreht werden, so dass die vorauslaufende Kante des Bogens 3 geändert wird. Durch die Drehung der Bogen um 90° ist es in vorteilhafter Weise möglich, auch den zweiten Längsfalz bei voller Transportgeschwindigkeit der Bogen zu erzeugen. Wie Fig. 1 am besten zeigt, wird der durch die Teller 4" und 5" freigegebene Bogen 3 über eine Bandleitung 6 an einen Greiferzylinder 7 übergeben. An den Greiferzylinder 7 ist ein Falzklappen 9 tragender Falzklappenzylinder 10 angestellt. Durch die am Greiferzylinder 7 angeordneten Falzmesser kann somit am Falzklappenzylinder 10 in der gleichen Weise der zweite Längsfalz erzeugt werden wie der erste Querfalz am Falzklappenzylinder 1.With the help of these plates 4, 5, the sheet can be rotated by a certain angular amount, here by exactly 90 °, so that the leading edge of the sheet 3 is changed. By rotating the sheets by 90 °, it is advantageously possible to also produce the second longitudinal fold at full transport speed of the sheets. As best shown in FIG. 1, the sheet 3 released by the plates 4 "and 5" is transferred to a gripper cylinder 7 via a ribbon cable 6. On the gripper cylinder 7, a folding jaw cylinder 9 carrying folding jaws 10 is employed. By means of the folding blades arranged on the gripper cylinder 7, the second longitudinal fold can be produced on the folding jaw cylinder 10 in the same way as the first transverse fold on the folding jaw cylinder 1.

Dem Falzklappenzylinder 10 angeordnet ist ein herkömmliches Schaufelrad 11 zur Aufnahme der Falzexemplare, das diese an eine Auslage, beispielsweise eine Bandauslage 12, weitergibt.Arranged on the folding jaw cylinder 10 is a conventional paddle wheel 11 for receiving the folded copies, which this passes on to a delivery, for example a belt delivery 12.

Fig. 3 zeigt im Schnitt die Steuerung und Führung der Teller 4 und 5 entlang der Linie 111-111 in der Darstellung gemäss Fig. 1. Dabei bildet der untere Teller 5 ein Widerlager für den oberen Teller 4. Der Teller 5 ist fest mit einer Achse 13 verbunden, die leicht drehbar, aber axial fixiert in einem Wälzlagerpaar 14 angeordnet ist. Auf den Wälzlagern 14 sitzt eine Büchse 15, die an einem Zahnriemen 16 befestigt, beispielsweise an diesen einvulkanisiert ist. Der Zahnriemen 16 bewegt sich mit der Geschwindigkeit der von dem Falzklappenzylinder 1 zu der Bandleitung 6 zu transportierenden Bogen 3. Die Büchse 15 ist über ein Lager 17 in einer Stützrolle 18 angeordnet, die sich wiederum auf einer entlang des Bogenförderweges angeordneten Kurvenbahn 19 abstützt. Der Zahnriemen 16 wird um ein Antriebszahnrad 20 geführt und durch dieses mit Maschinengeschwindigkeit angetrieben.3 shows in section the control and guidance of the plates 4 and 5 along the line 111-111 in the illustration according to FIG. 1. The lower plate 5 forms an abutment for the upper plate 4. The plate 5 is fixed with a Axis 13 connected, which is easily rotatable but axially fixed in a pair of bearings 14. A bushing 15 is seated on the roller bearings 14 and is fastened to a toothed belt 16, for example vulcanized to it. The toothed belt 16 moves at the speed of the sheets 3 to be transported from the folding jaw cylinder 1 to the belt line 6. The bush 15 is arranged via a bearing 17 in a support roller 18, which in turn is supported on a cam track 19 arranged along the sheet conveying path. The toothed belt 16 is guided around a drive gear 20 and driven by this at machine speed.

Der obere Teller 4 ist ebenfalls drehfest mit einer Achse 21 verbunden. Eine auf der Achse 21 drehbare, aber axial nicht verschiebliche Stützrolle 22 wird über ein die Achse 21 umfassendes Axiallager 23 durch eine Druckfeder 24 gegen eine Kurvenbahn 25 gedrückt. Die Stützrolle 22 sitzt dabei auf einem Lager 26. Die Kurvenbahn 25 ist, wie gestrichelt angedeutet, so geformt, dass während des Bogentransportweges der obere Teller 4 bei der Übernahme des Bogens 3 von der Bandleitung 2 eine obere, d.h. eine von dem unteren Teller abgehobene Position einnimmt und, wie in Fig. 3 dargestellt, zwecks Erfassung des zu transportierenden Bogens 3 abgesenkt, d. h. gegen den unteren Teller 5 gepresst wird. Der obere Teller 4" wird zwecks Übergabe des Bogens 3 an die Bandleitung 6 wieder durch die Kurvenbahn 25 angehoben. Die Kurvenbahn 25 bewirkt also, dass die oberen Teller 4, 4' und 4" zur rechten Zeit Auf-und Abwärtsbewegungen durchführen, während sich diese zusammen mit den unteren Tellern 5, 5' und 5" mit Bogengeschwindigkeit bewegen.The upper plate 4 is also rotatably connected to an axis 21. A support roller 22 which is rotatable on the axis 21 but cannot be displaced axially is pressed against a cam track 25 by a compression spring 24 via an axial bearing 23 which comprises the axis 21. The support roller 22 is seated on a bearing 26. The cam track 25 is, as indicated by dashed lines, shaped so that the upper plate 4 during the sheet transport path when the sheet 3 is taken over from the strip line 2, an upper, i.e. assumes a position lifted off the lower plate and, as shown in FIG. 3, is lowered for the purpose of detecting the sheet 3 to be transported, i. H. is pressed against the lower plate 5. The upper plate 4 "is raised again by the curved track 25 for the purpose of transferring the sheet 3 to the strip line 6. The curved track 25 therefore causes the upper plates 4, 4 'and 4" to perform upward and downward movements at the right time while move them together with the lower plates 5, 5 'and 5 "at sheet speed.

Wie Fig. 3 weiterhin erkennen lässt, ist auch die Achse 21 über ein Wälzlagerpaar 27 leicht drehbar, jedoch axial verschieblich in einer Büchse 28 gelagert. Die Büchse 28 ist in einem oberen Zahnriemen 29 einvulkanisiert, der durch ein Antriebszahnrad 30 ebenfalls mit Bogengeschwindigkeit angetrieben wird. Die Büchse 28 stützt sich gegen die Druckfeder 24 über einem Wälzlager 31 ab, auf dem eine Stützrolle 32 angeordnet ist. Letztere wird entlang einer Kurvenbahn 33 geführt, die die gleiche Funktion wie die Kurvenbahn 19 für den unteren Teller 5 ausübt. Ein Zahnriemenrad 34 ist fest mit der Achse 21 verbunden und wird durch einen Zahnriemen 35 angetrieben. Letzterer ist um ein Zahnriemenrad 36 geführt, das von einem Schrittschaltgetriebe 37, beispielsweise einem Schrittschaltmotor, über Kegelräder 38, 39 sowie Stirnräder 40, 41 und eine Hohlachse 42 angetrieben wird. Dadurch kann die Achse 21 und somit der obere Teller 4 und der untere Teller 5 um einen definierten Winkelbetrag gedreht werden, um den auch der zwischen den Tellern 4, 5 befindliche Bogen 3 mitgedreht wird.As can also be seen in FIG. 3, the axis 21 can also be rotated easily via a pair of roller bearings 27, but is axially displaceably mounted in a bushing 28. The sleeve 28 is vulcanized into an upper toothed belt 29, which is also driven by a drive gear 30 at sheet speed. The sleeve 28 is supported against the compression spring 24 via a roller bearing 31 on which a support roller 32 is arranged. The latter is guided along a curved path 33, which performs the same function as the curved path 19 for the lower plate 5. A toothed belt wheel 34 is fixedly connected to the axis 21 and is driven by a toothed belt 35. The latter is guided around a toothed belt wheel 36, which is driven by a stepping gear 37, for example a stepping motor, via bevel gears 38, 39 as well as spur gears 40, 41 and a hollow shaft 42. As a result, the axis 21 and thus the upper plate 4 and the lower plate 5 can be rotated by a defined angular amount by which the sheet 3 located between the plates 4, 5 is also rotated.

Aus Fig. 1 in Verbindung mit Fig. 2 geht hervor, dass die erfindungsgemässe Bogendrehvorrichtung sechs Tellerpaare hier umfasst. Entlang des Bogentransportweges sind die Tellerpaare 4, 5; 4', 5' und 4" und 5" gezeigt, während auf der gegenüberliegenden Seite (Fig. 2) drei «rücklaufende» Tellerpaare, die nicht näher bezeichnet sind, zu sehen sind. Die sechs Tellerpaare werden auf einer ovalen Bahn innerhalb der Kurvenbahnen 19,25 und 33 geführt. Diese Bahn verläuft von dem Punkt 43 bis zum Punkt 44 in Richtung des Pfeiles 45 in einer Geraden. Bevor beispielsweise das Tellerpaar 4, 5 den Punkt 43 erreicht, sind die Teller voneinander beabstandet, d.h. der obere Teller 4 ist durch die Kurvenbahn 25 angehoben.1 in connection with FIG. 2 shows that the sheet turning device according to the invention comprises six pairs of plates here. Along the sheet transport path, the plate pairs 4, 5; 4 ', 5' and 4 "and 5" are shown, while on the opposite side (FIG. 2) three "returning" plate pairs, which are not identified, can be seen. The six pairs of plates are guided on an oval path within the curved paths 19, 25 and 33. This path runs from point 43 to point 44 in the direction of arrow 45 in a straight line. For example, before the pair of plates 4, 5 reaches point 43, the plates are spaced apart, i.e. the upper plate 4 is raised by the cam track 25.

Der Kurvenhub der Kurvenbahn 25 ist so festgelegt, dass zwecks Erfassung des von der Bandleitung 2 zu übernehmenden Bogens 3 der obere Teller 4 in Richtung zum unteren Teller 5 eine schnelle Abwärtsbewegung ausführen kann. Der obere Teller 4 wird dann durch die Kraft der Druckfeder 4 gegen den unteren Teller 5 gepresst, so dass der zu transportierende und zu drehende Bogen 3 exakt festgehalten werden kann. Der Antrieb des Schrittschaltgetriebes 37 war zunächst so geschaltet, dass der obere Teller 4 sich ohne Eigendrehung mit der Bogentransportgeschwindigkeit bewegte. Nachdem ein Bogen 3 sicher erfasst wurde, erhält nunmehr der obere Teller 4 vom Getriebe 37 einen definierten Drehimpuls, der so festgelegt ist, dass die Drehung kurz vor der Erreichung des Punktes 44 genau 90° beträgt und dann zum Stillstand kommt. Im selben Moment, in dem der um 90° gedrehte Bogen 3 von der Bandleitung 6 erfasst wird, wird, bedingt durch den Verlauf der Steuerkurve der Kurvenbahn 25, der obere Teller 4 einer schnellen Aufwärtsbewegung ausgesetzt, um den zu übergebenden Bogen 3 freizugeben. Bei dieser schnellen Aufwärtsbewegung wird die Druckfeder 24 zusammengedrückt. Das sich in Fig. 1 in der linken Stellung befindliche Tellerpaar 4", 5" kehrt nach Abgabe des Bogens 3 an die Bandleitung 6 entlang der ovalen Bahn zum Punkt 43 zurück, wo der Vorgang von neuem beginnt.The curve stroke of the cam track 25 is defined in such a way that the upper plate 4 can execute a rapid downward movement in the direction of the lower plate 5 in order to detect the arc 3 to be taken over by the strip line 2. The upper plate 4 is then pressed by the force of the compression spring 4 against the lower plate 5, so that the sheet 3 to be transported and rotated can be held exactly. The drive of the stepping transmission 37 was initially switched so that the upper plate 4 moved without self-rotation at the sheet transport speed. After a sheet 3 has been reliably detected, the upper plate 4 now receives a defined angular momentum from the gear 37, which is defined such that the rotation is exactly 90 ° shortly before the point 44 is reached and then comes to a standstill. At the same time that the sheet 3 rotated by 90 ° is picked up by the ribbon line 6, the upper plate 4 is subjected to a rapid upward movement due to the course of the control curve of the curved track 25 in order to release the sheet 3 to be transferred. During this rapid upward movement, the compression spring 24 is compressed. The plate pair 4 ", 5" in the left position in FIG. 1 returns after delivery of the sheet 3 to the strip line 6 along the oval path to point 43, where the process begins again.

Wie Fig. 2 erkennen lässt, befinden sich zwischen den Punkten 43 und 44 mehrere Tellerpaare 4, 5; 4', 5' sowie 4", 5", die zur selben Zeit verschiedene Drehimpulse erhalten müssen. Für einander unmittelbar nachfolgende Tellerpaare müssen verschiedene Getriebe zum Drehen der Teller vorhanden sein, wenn sich zwischen der Bogenannahmestelle und der Bogenabnahmestelle mehrere Tellerpaare gleichzeitig befinden. Bei dem hier beschriebenen Ausführungsbeispiel können jeweils drei Tellerpaare durch eine Zahnriemen angetrieben werden, während für die restlichen drei Tellerpaare ein zweiter Antrieb benötigt wird. Gemäss Fig. 3 ist deshalb ein weiteres Getriebe, beispielsweise ein weiterer Schrittschaltmotor 46 vorgesehen, der über Kegelräder 47 und 48 Stirnräder 49 und 50 und von diesen die Büchse 51 und ein Zahnriemenrad 52 antreibt, um das ein drei Tellerpaare antreibender Zahnriemen 53 geführt ist. Mit dem Zahnriemen 53 stehen die drei zwecks Drehung der oberen Teller benötigten Zahnriemenräder in Eingriff. So zeigt beispielsweise Fig. 3 das Zahnriemenrad 54 auf einer Achse 21', die dem oberen Teller 4' zugeordnet ist. Aus Fig. 1 wird dabei deutlich, dass einander folgende Tellerpaare durch verschiedene Getriebe getreht werden. So treibt das Schrittschaltgetriebe 37 über das Zahnriemenrad 34 die Achse 21 des oberen Tellers 4 und das Schrittschaltgetriebe 46 über das Zahnriemenrad 54 die Achse 21' des oberen Tellers 4' an.2, there are several plate pairs 4, 5 between points 43 and 44; 4 ', 5' and 4 ", 5", which must receive different angular momentum at the same time. For immediately following pairs of plates, different gears must be available to turn the plates if there are several pairs of plates between the sheet acceptance point and the sheet take-off point. In the embodiment described here, three pairs of plates can be driven by a toothed belt, while for the rest Lichen three pairs of plates a second drive is required. 3 is therefore another gear, for example another stepping motor 46 is provided which drives bevel gears 47 and 48 spur gears 49 and 50 and from these the sleeve 51 and a toothed belt wheel 52, around which a three plate pairs driving toothed belt 53 is guided. With the toothed belt 53, the three toothed belt wheels required for the rotation of the upper plates are engaged. For example, Fig. 3 shows the toothed belt wheel 54 on an axis 21 ', which is assigned to the upper plate 4'. From Fig. 1 it is clear that successive pairs of plates are rotated by different gears. Thus, the indexing gear 37 drives the axis 21 of the upper plate 4 via the toothed belt wheel 34 and the indexing gear 46 drives the axis 21 'of the upper plate 4' via the toothed belt wheel 54.

Fig. 1 zeigt noch eine weitere vorteilhafte Ausbildung der erfindungsgemässen Anordnung. Durch die Verwendung eines Heftzylinders 55 ist in einfacher Weise eine Heftung im zweiten Längsfalz (gemeint ist der sogenannte dritte Falz) möglich. Dieser Heftzylinder 55, eingebaut in einen austauschbaren Heftapparat, ist problemlos auch im ersten Querfalz verwendbar. Desweiteren kann bei abgeschalteter zusätzlicher Drehung der Antriebe 37, 46 ein normaler Transport der Bogen erfolgen. In diesem Fall laufen die Riemen 35 und 54 mit Bogengeschwindigkeit. Dadurch lässt sich der Querfalzvorgang wiederholen, ein sogenannter zweiter Querfalz mit Heftung ist in diesem Falle möglich. Setzt man hingegen die Falzmesser 8 ausser Funktion und verwendet dafür Greifer 56 am Greiferzylinder 7 und 57 am Falzklappenzylinder 10, so ist eine normale Auslage der mit lediglich einen ersten Querfalz versehenen Exemplare möglich, ohne dass dafür ein komplizierter Umschaltvorgang erforderlich ist. Der in bekannter Weise im Falztrichter 1 und in einem Falzklappenzylinder quergefalzte Bogen würde ohne Drehung von den Greifern 56 des Greiferzylinders 7 erfasst, von den Greifern 57 des Falzklappenzylinders 10 übernommen und ohne weiteren Falz ausgelegt. Durch die erfindungsgemässe Anordnung ist somit eine problemlose und einfache Umstellung auf verschiedene Falzarten möglich.1 shows yet another advantageous embodiment of the arrangement according to the invention. By using a stapling cylinder 55, stapling in the second longitudinal fold (meaning the so-called third fold) is possible in a simple manner. This stapling cylinder 55, installed in an exchangeable stapler, can also be used in the first cross fold without any problems. Furthermore, when the additional rotation of the drives 37, 46 is switched off, the sheets can be transported normally. In this case belts 35 and 54 run at sheet speed. This enables the cross-folding process to be repeated, a so-called second cross-folding with stapling is possible in this case. On the other hand, if the folding knife 8 is deactivated and grippers 56 on the gripper cylinder 7 and 57 on the folding jaw cylinder 10 are used, normal delivery of the copies provided with only a first transverse fold is possible without a complicated switching process being necessary. The sheet, which is folded in a known manner in the former 1 and in a folding jaw cylinder, would be gripped by the grippers 56 of the gripper cylinder 7 without rotation, taken over by the grippers 57 of the folding jaw cylinder 10 and laid out without further folding. The arrangement according to the invention thus enables a problem-free and simple changeover to different types of folds.

Bei der vorangehend beschriebenen Ausführungsform erfolgt die Umlenkung der verwendeten Zahnriemen jeweils über Zahnriemenräder. In Fig. 2 ist lediglich die Umlenkung des Zahnriemens 29 rechts um das Antriebszahnrad 30 und links um ein Zahnriemenrad 58 zu sehen. Der Antrieb für das Antriebszahnrad 30 erfolgt über einen nicht gezeigten Hauptantrieb, der mit einem Hauptantriebszahnrad 59 verbunden ist, das drehfest auf der Hauptantriebswelle 60 angeordnet ist. In der gleichen Weise erfolgt der Antrieb des Antriebszahnrades 20 für den unteren Zahnriemen 16 über den gleichen Hauptantrieb, und zwar wird dieser über ein Hauptantriebszahnrad 61 auf die untere Hauptantriebswelle 62 eingeleitet.In the embodiment described above, the toothed belts used are deflected via toothed belt wheels. In Fig. 2, only the deflection of the toothed belt 29 on the right around the drive gear 30 and on the left around a toothed belt wheel 58 can be seen. The drive gear 30 is driven by a main drive, not shown, which is connected to a main drive gear 59, which is arranged on the main drive shaft 60 in a rotationally fixed manner. In the same way, the drive gear 20 for the lower toothed belt 16 is driven by the same main drive, namely that it is introduced to the lower main drive shaft 62 via a main drive gear 61.

Da, wie beschrieben, bei der im Ausführungsbeispiel verwendeten Anzahl an Tellerpaaren zwei Getriebe 37, 46 verwendet werden, erfolgt in vorteilhafter Weise die Einleitung des Antriebes zur Drehung von drei Tellerpaaren über die auf der Hauptantriebswelle 60 gelagerte Büchse 42 zu dem Zahnriemen 35 und für weitere drei Tellerpaare über die auf der Büchse 42 gelagerte Büchse 51 zu dem Zahnriemen 53. Das obere System ist über ein Lager 63 in einem Gestelll 64 ortsfest angeordnet. Das untere System kann über Lager 65 ebenfalls im Gestell 64 positioniert sein.Since, as described, two gears 37, 46 are used in the number of plate pairs used in the exemplary embodiment, the drive is advantageously initiated for the rotation of three plate pairs via the bushing 42 mounted on the main drive shaft 60 to the toothed belt 35 and for others three pairs of plates via the bushing 51 mounted on the bushing 42 to the toothed belt 53. The upper system is arranged in a stationary manner via a bearing 63 in a frame 64. The lower system can also be positioned in frame 64 via bearing 65.
