Description

Beschreibungdescription
Falztrommeln eines FalzapparatesFolding drums of a folder
Die Erfindung betrifft Falztrommeln eines Falzapparates gemäß dem Oberbegriff des Anspruchs 1 , 3 oder 5.The invention relates to folding drums of a folding apparatus according to the preamble of claim 1, 3 or 5.
Die Aufgabe einer Falztrommel ist, ein in dem Falzapparat zu falzendes Produkt zeitweilig zu transportieren und in einer zum Falzen geeigneten Orientierung je nach Bauart des Falzapparates in eine Falzklappe eines Falzklappenzylinders zu drücken oder an zwei Falzrollen zu übergeben, die das Produkt mit der gewünschten Falzlinie voran in einen zwischen ihnen gebildeten Spalt einziehen und auf diese Weise falzen. Zu diesem Zweck weist die Falztrommel eine Mehrzahl von beweglichen Falzmessern auf, die durch Öffnungen in einem Mantel der Falztrommel ausfahrbar sind, um das zu falzende Produkt in eine Falzklappe oder einen Spalt zwischen zwei Falzrollen einzuführen.The task of a folding drum is to temporarily transport a product to be folded in the folder and to press it into a folder of a folder cylinder in an orientation suitable for folding, depending on the design of the folder, or to transfer it to two folder rollers that advance the product with the desired folding line pull into a gap formed between them and fold in this way. For this purpose, the folding drum has a plurality of movable folding knives which can be extended through openings in a jacket of the folding drum in order to introduce the product to be folded into a folding flap or a gap between two folding rollers.
Die Bewegung der Falzmesser ist über ein Getriebe an die Drehung der Falztrommel gekoppelt. Es sind Falzapparate bekannt, bei denen für eines von zwei Falzmessern die Kopplung aufhebbar und das Falzmesser stilliegbar ist. Diese Stilllegung ermöglicht die sogenannte Sammelproduktion. Ein Produkt kann an einer Übergabestelle an die Falztrommel übergeben werdeη und auf dieser eine vollständige Umdrehung zurücklegen, ohne von einem Falzmesser abgestoßen zu werden. Wenn das Produkt die Übernahmestelle erneut passiert, wird über das erste ein zweites Produkt gelegt und beide werden gemeinsam von der Falztrommel weitergeführt. Wenn nun beide Produkte gemeinsam vom Falzmesser abgestoßen werden, werden sie gemeinsam gefalzt.The movement of the folding knives is coupled to the rotation of the folding drum via a gear. Folding apparatuses are known in which the coupling can be released and the folding knife can be locked for one of two folding knives. This decommissioning enables so-called collective production. A product can be handed over to the folding drum at a transfer point and cover a complete revolution on it, without being pushed off by a folding knife. If the product passes the takeover point again, a second product is placed over the first and both are carried on together by the folding drum. If both products are now pushed off by the folding knife, they are folded together.
Die DE 195 11 054 C2 offenbart einen Antrieb für ein Falzmesser einer Falztrommel, wobei der Antrieb des Falzmessers über ein zentrales Zahnrad erfolgt. Der Erfindung liegt die Aufgabe zugrunde, Falztrommeln eines Falzapparates zu schaffen.DE 195 11 054 C2 discloses a drive for a folding knife of a folding drum, wherein the folding knife is driven via a central toothed wheel. The invention has for its object to provide folding drums of a folder.
Die Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 , 3 oder 5 gelöst.The object is achieved by the features of claim 1, 3 or 5.
Eine der beiden Zahnradscheiben ist fest, während die andere Zahnradscheibe je nach gewählter Produktion rotiert.One of the two gear discs is fixed, while the other gear disc rotates depending on the selected production.
Zum Einkuppeln bleibt die Falztrommel in eine definierten Position stehen, da die Zahnkupplung eindeutig ist. Alternativ kann die Zahnkupplung schleifend bei drehender Falztrommel einrasten.When engaging, the folding drum remains in a defined position because the tooth coupling is clear. As an alternative, the toothed clutch can slide into place while the folding drum is rotating.
Die Umschaltung von Einzel- auf Sammelproduktion ist damit schneller und einfacher möglich als mit bisherigen Konstruktionen.Switching from individual to collective production is faster and easier than with previous designs.
Für die für Einzelproduktion erforderliche Kopplung der ersten und zweiten Radscheibe aneinander sind diese zweckmäßigerweise mit komplementären Verzahnungen ausgestattet, die durch axiales Verschieben der ersten Radscheibe in Eingriff bzw. außer Eingriff gebracht werden können.For the coupling of the first and second wheel disks to one another required for individual production, these are expediently equipped with complementary toothings which can be brought into or out of engagement by axially displacing the first wheel disk.
Diese Verzahnungen sind z. B. durch ungleichmäßige Zahnabstände oder -breiten so ausgelegt, dass sie nur in einer kleinen Zahl m von gleichmäßig verteilten Drehstellungen der zwei Radscheiben relativ zu einander in Eingriff bringbar sind. Die Zahl m hängt vom Übersetzungsverhältnis der Getriebegruppen ab. Wenn bei als festgehalten angenommenem Rahmen der Getriebeeinheit die Getriebegruppen eine Umdrehung des zentralen Rades in eine ganze Zahl n von Umdrehungen der Falzmesser umsetzen, so kann m jeder beliebige ganzzahlige Teiler von n einschließlich 1 oder n sein. Dadurch wird sichergestellt, dass ein Zurückschalten auf Einzelproduktion nur stattfindet, wenn das zuvor bei Sammelproduktion deaktivierte Falzmesser sich in einer korrekten Phasenlage befindet. Insbesondere kann eine einzige eindeutige Stellung festgelegt werden.These gears are e.g. B. designed by uneven tooth spacings or widths so that they can only be brought into engagement with each other in a small number m from evenly distributed rotational positions of the two wheel disks. The number m depends on the gear ratio of the gear groups. If, with the frame of the gear unit assumed to be fixed, the gear groups convert one revolution of the central wheel into an integer number n of revolutions of the folding blades, then m can be any integer divisor of n including 1 or n. This ensures that a switch back to individual production only takes place if the folding knife previously deactivated during collective production is in the correct phase position. In particular, a single clear position can be determined.
Vorzugsweise weist die erste Radscheibe eine weitere Verzahnung auf, die zu einer Verzahnung am Rahmen der Getriebeeinheit komplementär ist und durch Verschieben der ersten Zahnradscheibe mit dieser in Eingriff bringbar ist. Diese Verzahnung dient zum Arretieren des an die erste Radscheibe gekoppelten Falzmessers bei der Sammelproduktion. Diese Verzahnungen sind in einer Vielzahl von Drehstellungen miteinander in Eingriff bringbar, so dass die Umschaltung von Einzel- auf Sammelproduktion bei beliebiger Orientierung der Falztrommel stattfinden kann.The first wheel disk preferably has a further toothing which is complementary to a toothing on the frame of the gear unit and which can be brought into engagement with it by displacing the first gear wheel disk. This toothing is used to lock the folding knife coupled to the first wheel disc during collective production. These gears can be brought into engagement with one another in a large number of rotational positions, so that the switchover from individual to collective production can take place with any orientation of the folding drum.

Im Trommelmantel 01 der in Fig. 1 gezeigten Falztrommel sind drei Gruppen von Schlitzen 02 jeweils in einem Winkelabstand von 120° in Umfangsrichtung gebildet. An der in der Fig. 1 oben liegenden Gruppe von Schlitzen 02 ist eine Mehrzahl austretender Vorsprünge 03 gezeigt, die Teil eines Falzelementes 04, z. B. eines Falzmessers 04, sind. Das Falzmesser 04 ist auf einem Träger angeordnet, der mit Bezug auf Fig. 2 noch genauer erläutert wird.In the drum jacket 01 of the folding drum shown in FIG. 1, three groups of slots 02 are each formed at an angular distance of 120 ° in the circumferential direction. On The group of slits 02 lying at the top in FIG. 1 shows a plurality of emerging projections 03, which are part of a folding element 04, for. B. a folding knife 04 are. The folding knife 04 is arranged on a carrier, which will be explained in more detail with reference to FIG. 2.
Am Trommelmantel 01 können weitere Funktionsgruppen wie etwa Greifer oder Punkturnadelleisten zum Halten eines an der Falztrommel mitgeführten Produkts angeordnet sein, die zur Vereinfachung der Darstellung in Fig. 1 nicht gezeigt sind und auch nicht beschrieben werden, da sie dem Fachmann bekannt sind und von der Erfindung nicht weitergebildet werden.Further functional groups such as grippers or pin needles for holding a product carried on the folding drum can be arranged on the drum jacket 01, which are not shown for the sake of simplicity of the illustration in FIG. 1 and are also not described, since they are known to the person skilled in the art and from the invention no further training.
An den Stirnflächen des Trommelmantels 01 befinden sich zwei Flansche 06 mit einer geräumigen, zur Längsachse des Trommelmantels 01 konzentrischen Öffnung 07. An die Öffnung 07 ist ein Schaft 08 angeformt, der zur drehbaren Lagerung der Falztrommel im (nicht dargestellten) Gestell eines Falzapparates dient.On the end faces of the drum jacket 01 there are two flanges 06 with a spacious opening 07 which is concentric with the longitudinal axis of the drum jacket 01. A shaft 08 is formed on the opening 07 and is used for the rotatable mounting of the folding drum in the frame (not shown) of a folder.
Eine Welle 09, die die innere Struktur der Falztrommel trägt, erstreckt sich exzentrisch durch die Öffnung 07.A shaft 09, which carries the inner structure of the folding drum, extends eccentrically through the opening 07.
Wie Fig. 2 zeigt, trägt die Welle 09 im Innern der Falztrommel zwei in entgegengesetzte Richtungen abstehende Arme 11 und eine Getriebeeinheit 12, die zwei um zur Welle 09 parallele Achsen drehbare Falzmesserwellen 13; 28 tragen. Das Gehäuse der Getriebeeinheit 12 ist mit dem dem Betrachter in Fig. 2 zugewandten Abschnitt der Welle 09 starr verbunden und im Innern der Falztrommel gemeinsam mit diesem drehbar. Jenseits der Getriebeeinheit 12 in der Perspektive der Fig. 2 ist die Welle 09 durch einen Wellenabschnitt 14 verlängert, der hier aus Gründen, die in Verbindung mit Fig. 3 deutlich werden, als zweite Zahnradscheibenwelle 14 bezeichnet wird. Diese zweite Zahnradscheibenwelle 14 ist vorgesehen, um in einer Seitenplatte des Falzapparats nicht drehbar montiert zu werden. Durch einen axialen Hohlraum der zweiten Zahnradscheibenwelle 14 verläuft ein erster Wellenabschnitt 16, eine sogenannte erste Zahnradscheibenwelle 16.As shown in FIG. 2, the shaft 09 carries two arms 11 projecting in opposite directions inside the folding drum and a gear unit 12 which has two folding knife shafts 13; 28 wear. The housing of the gear unit 12 is rigidly connected to the section of the shaft 09 facing the viewer in FIG. 2 and can be rotated together with the inside of the folding drum. Beyond the gear unit 12 in the perspective of FIG. 2, the shaft 09 is extended by a shaft section 14, which is referred to here as a second gear disk shaft 14 for reasons that will become clear in connection with FIG. 3. This second gear disk shaft 14 is provided so as not to be rotatably mounted in a side plate of the folder. Through an axial cavity the second Gear wheel shaft 14 runs a first shaft section 16, a so-called first gear wheel shaft 16.
Fig. 3 veranschaulicht den inneren Aufbau der Getriebeeinheit 12. Die zwei Zahnradscheibenwellen 16; 14 sind drehbar durch eine Öffnung des Gehäuses 17 oder Rahmens der Getriebeeinheit 12 durchgeführt und tragen jeweils eine erste Zahnradscheibe 18 bzw. eine zweite Zahnradscheibe 19. Da die zweite Zahnradscheibe 19 starr mit der zweiten Zahnradscheibenwelle 14 verbunden ist, folgt sie einer Drehung der Getriebeeinheit 12 um die Achse der Welle 09 nicht. So treibt sie, wenn die Getriebeeinheit 12 rotiert, eine Getriebegruppe an, die aus einem um eine mit dem Gehäuse 17 verbundene Achse drehbaren Zwischenrad 21 und einem an der Falzmesserwelle 13 befestigten Zahnrad 22 gebildet ist. Während die Getriebeeinheit 12 um die Achse der Welle 09 rotiert, bewegt sich die Falzmesserwelle 13 auf einer Kreisbahn um die Welle 09 und rotiert gleichzeitig um ihre eigene Achse. Die Spitze des an ihr montierten Falzmessers 04 beschreibt dabei eine Zykloide. Aufgrund der exzentrischen Anordnung der Welle 09 in Bezug auf den Trommelmantel 01 tritt das Falzmesser 04 dabei nur an einer Stelle seiner Zykloidenbahn durch die Schlitze 02 des Trommelmantels 01 aus. Das Übersetzungsverhältnis der Getriebegruppe 19, 21 , 22 muss so festgelegt sein, dass mit jeder Umdrehung der Getriebeeinheit 12 die Falzmesserwelle 13 eine ganze Zahl von Umdrehungen um sich selbst vollführt. Im hier betrachteten Fall ist das Übersetzungsverhältnis so gewählt, dass bei als festgehalten angenommenem Gehäuse 17 eine Umdrehung der zweiten Zahnradscheibe 19 n = 3 Umdrehungen des Falzmessers 04 antreibt.Fig. 3 illustrates the internal structure of the gear unit 12. The two gear disk shafts 16; 14 are rotatably guided through an opening of the housing 17 or frame of the gear unit 12 and each carry a first gear disk 18 and a second gear disk 19. Since the second gear disk 19 is rigidly connected to the second gear disk shaft 14, it follows a rotation of the gear unit 12 around the axis of shaft 09. Thus, when the gear unit 12 rotates, it drives a gear group which is formed from an intermediate wheel 21 rotatable about an axis connected to the housing 17 and a gear wheel 22 fastened to the folding blade shaft 13. While the gear unit 12 rotates about the axis of the shaft 09, the folding knife shaft 13 moves in a circular path around the shaft 09 and simultaneously rotates about its own axis. The tip of the folding knife 04 attached to it describes a cycloid. Due to the eccentric arrangement of the shaft 09 in relation to the drum jacket 01, the folding knife 04 only emerges at one point on its cycloid path through the slots 02 of the drum jacket 01. The transmission ratio of the gear group 19, 21, 22 must be set so that with each revolution of the gear unit 12, the folding blade shaft 13 makes a whole number of revolutions around itself. In the case considered here, the transmission ratio is selected such that, with the housing 17 assumed to be held in place, one revolution of the second gear wheel 19 drives n = 3 revolutions of the folding knife 04.
Die erste Zahnradscheibe 18 ist durch axiales Verschieben der ersten Zahnradscheibenwelle 16 zwischen zwei Stellungen verschiebbar. In einer ersten Stellung koppelt sie über an den einander zugewandten Stirnseiten der zwei Zahnradscheiben 18; 19 angeordnete Verzahnungen 23; 24 an die zweite Zahnradscheibe 19 und wird so in Bezug auf das Gestell des Falzapparats unbeweglich gehalten. In dieser Stellung treibt die erste Zahnradscheibe 18 eine andere Getriebegruppe 18, 26, 27 an, die aus einem Zwischenrad 26 und einem Zahnrad 27 der zweiten Falzmesserwelle 28 besteht. In diesem Zustand bewegt sich das Falzmesser 04 der zweiten Falzmesserwelle 28 auf der gleichen Zykloidenbahn wie das der ersten Falzmesserwelle 13. Dieser Zustand entspricht der Doppelproduktion.The first gear disk 18 is displaceable between two positions by axially displacing the first gear disk shaft 16. In a first position, it couples over on the mutually facing end faces of the two gear wheel disks 18; 19 arranged teeth 23; 24 to the second gear disc 19 and is held immovable with respect to the frame of the folder. Drives in this position the first gear wheel 18 on another gear group 18, 26, 27, which consists of an intermediate gear 26 and a gear 27 of the second folding blade shaft 28. In this state, the folding knife 04 of the second folding knife shaft 28 moves on the same cycloid path as that of the first folding knife shaft 13. This state corresponds to the double production.
In der zweiten Stellung der ersten Zahnradscheibe 18 koppelt diese über eine an ihrer zweiten Stirnfläche angeordnete Verzahnung 29 an eine fest mit dem Gehäuse 17 verbundene Verzahnung 31. In dieser Stellung folgt die erste Zahnradscheibe 18 der Drehung des Gehäuses 17, und das Falzmesser 04 der zweiten Falzmesserwelle 28 bewegt sich auf einer Kreisbahn, auf der es nicht aus der Falztrommel austritt, d. h. es bewegt sich relativ zum Zylinder nicht. Dieser Zustand entspricht der Sammelproduktion.In the second position of the first gear wheel 18, it couples via a toothing 29 arranged on its second end face to a toothing 31 which is fixedly connected to the housing 17. In this position, the first gear wheel 18 follows the rotation of the housing 17 and the folding knife 04 the second Folding knife shaft 28 moves on a circular path on which it does not emerge from the folding drum, i. H. it does not move relative to the cylinder. This condition corresponds to the collective production.
Die Verzahnungen 29; 31 bestehen aus einer großen Zahl von gleichmäßig angeordneten Zähnen, die einen Eingriff der Verzahnungen 29; 31 ineinander in einer Vielzahl von jeweils nur durch kleine Drehwinkel voneinander getrennten Orientierungen erlauben. So genügt, auch wenn beim Verschieben der ersten Zahnradscheibe 18 gegen die Verzahnung 31 Zahnspitzen der Verzahnungen 29; 31 aufeinander treffen, eine geringfügige Drehung des Gehäuse 17, um einen Eingriff zu ermöglichen. Im Gegensatz dazu haben die Verzahnungen 23; 24, wie der Fig. 4 zu entnehmen ist, eine kleine Zahl von Zähnen 32, die ungleichmäßige Längen haben und in ungleichmäßigen Abständen angeordnet sind, um jeweils nur in drei Orientierungen der zwei Zahnradscheiben 18; 19 in Bezug aufeinander einen Eingriff zu gestatten. Durch dieses Merkmal wird sichergestellt, dass beim Wiederherstellen der Kopplung zwischen den Zahnradscheiben 18; 19 das Falzmesser 04 der zeitweilig stillgelegten zweiten Falzmesserwelle 28 die gleiche Lage hat wie vor Aufhebung der Kopplung. Dies kann es erforderlich machen, dass beim Umschalten von Sammel- auf Einzelproduktion die Falztrommel zunächst ein Stück weit langsam gedreht werden muss, bis die Verzahnungen 23; 24 in Eingriff gebracht werden können. Die Zähne 32 könnten auch so angeordnet sein, dass jeweils nur in einer einzigen Drehstellung ein Eingriff möglich ist.The teeth 29; 31 consist of a large number of uniformly arranged teeth, which engage the teeth 29; 31 allow each other in a variety of orientations separated from each other only by small angles of rotation. It is sufficient, even if, when the first gear disk 18 is moved against the teeth 31, tooth tips of the teeth 29; 31 meet, a slight rotation of the housing 17 to allow an engagement. In contrast, the teeth 23; 24, as can be seen from FIG. 4, a small number of teeth 32, which have uneven lengths and are arranged at uneven intervals, in order to in each case only in three orientations of the two gear wheel disks 18; 19 to allow intervention with respect to each other. This feature ensures that when restoring the coupling between the gear disks 18; 19 the folding knife 04 of the temporarily shut down second folding knife shaft 28 has the same position as before the coupling was released. This can make it necessary that when switching from collective to individual production, the folding drum must first be rotated slowly a bit until the toothings 23; 24 can be engaged. The teeth 32 could also be arranged such that an engagement is only possible in a single rotational position.
Wenn das Übersetzungsverhältnis der Getriebegruppen 19, 21 , 22; 18, 26, 27 z. B. n = 4 Umdrehungen der Falzmesserwellen 13; 28 pro Umdrehung der Zahnradscheiben 18; 19 entspräche, könnten die Zähne 32 auch so angeordnet sein, dass sie m = 1 , 2 oder 4 Eingriffsstellungen zulassen.If the gear ratio of the gear groups 19, 21, 22; 18, 26, 27 z. B. n = 4 revolutions of the folding knife shafts 13; 28 per revolution of the gear discs 18; 19 would correspond, the teeth 32 could also be arranged such that they allow m = 1, 2 or 4 engagement positions.
Die Veränderung der Drehzahl des Falzelements 04 erfolgt über eine Stelleinrichtung, die koaxial zur Rotationsachse 09, 14, 16 des Trägers, d. h. der Welle 09 bzw. des Wellenabschnittes 14 oder 16, insbesondere im Achszapfen, angeordnet ist.The speed of the folding element 04 is changed via an adjusting device which is coaxial to the axis of rotation 09, 14, 16 of the carrier, i. H. the shaft 09 or the shaft section 14 or 16, in particular in the journal, is arranged.
Die Rotationsachse der Falztrommel und die Rotationsachse 09, 14, 16 des Trägers des Falzelementes 04 sind exzentrisch zueinander angeordnet. Das Falzelement 04 ist an einer weiteren exzentrisch zur Rotationsachse 09, 14, 16 des Trägers angeordneten Rotationsachse 13; 28 rotierend angeordnet.The axis of rotation of the folding drum and the axis of rotation 09, 14, 16 of the carrier of the folding element 04 are arranged eccentrically to one another. The folding element 04 is located on a further axis of rotation 13 arranged eccentrically to the axis of rotation 09, 14, 16 of the carrier; 28 arranged rotating.
Der beschriebene Getriebeaufbau kann auch für eine Falztrommel verwendet werden, die anstelle von Falzmessern 04 Falzklappen 04 aufweist, also für einen Falzklappenzylinder. The gearbox construction described can also be used for a folding drum which has folding jaws 04 instead of folding blades 04, that is to say for a folding jaw cylinder.
