Description

Die Erfindung betrifft einen Sammelzylinder eines Falzapparats einer Druckmaschine nach dem Oberbegriff des Anspruchs 1.The invention relates to a collecting cylinder of a folding apparatus of a printing press according to the preamble of claim 1.

Falzapparate von Druckmaschinen dienen der Ausbildung von Falzen an bedruckten Bedruckstoffen, wobei zur Falzbildung ein bahnförmiger Bedruckstoff üblicherweise zuerst durch einen sogenannten Falztrichter geführt wird, um so am bahnförmigen sowie noch nicht durchtrennten Bedruckstoff einen Längsfalz auszubilden. Ausgehend vom Falztrichter wird der bahnförmige Bedruckstoff über mehrere Zugwalzen in Richtung auf einen Schneidmesserzylinder transportiert, wobei am Schneidmesserzylinder durch Querschneiden vom bahnförmigen Bedruckstoff Exemplare abgetrennt werden. Die am Schneidmesserzylinder vom bahnförmigen Bedruckstoff abgetrennten Exemplare werden von einem mit dem Schneidmesserzylinder zusammenwirkenden Zylinder gehalten bzw. übernommen, wobei Halteeinrichtungen dieses Zylinders für die vom Bedruckstoff abgetrennten Exemplare entweder als Punkturnadeln oder als Greifer ausgeführt sind. Abhängig hiervon ist der mit dem Schneidmesserzylinder zusammenwirkende Zylinder demnach entweder als Punkturnadelzylinder oder Greiferzylinder ausgebildet ist. Sollen Querfalze an den abgetrennten Exemplaren ausgebildet werden, so sind in den Punkturnadelzylinder oder Greiferzylinder Falzmesser integriert, welche die Exemplare unter Ausbildung von Querfalzen zwischen Falzklappen eines mit dem Punkturnadelzylinder oder Greiferzylinder zusammenwirkenden Falzklappenzylinders drücken. Sollen keine Querfalze an den Exemplaren ausgebildet werden, so sind in den Punkturnadelzylinder oder Greiferzylinder auch keine Falzmesser integriert. Die vom bahnförmigen Bedruckstoff abgetrennten und gegebenenfalls mit Querfalzen versehenen Exemplare können im Bereich eines Falztisches mit zweiten Längsfalzen versehen werden, die parallel zu dem im Falztrichter ausgebildeten Längsfalz verlaufen.Folders of printing presses are used for the formation of folds on printed substrates, wherein a web-shaped substrate is usually first performed by a so-called folder to form a fold so as to form a longitudinal fold on the web-shaped and not yet severed substrate. Starting from the former, the web-shaped substrate is transported over several draw rollers in the direction of a cutting blade cylinder, being separated on the cutting blade cylinder by cross-cutting of sheet-like substrate copies. The separated on the cutting blade cylinder from the web-shaped substrate copies are held or taken over by a cylinder cooperating with the cutting blade cylinder, said holding devices of this cylinder are executed for the separated from the substrate copies either as Punkturnadeln or as a gripper. Depending on this, the cooperating with the cutting blade cylinder cylinder is therefore designed either as a dot needle cylinder or gripper cylinder. Shall Querfalze be formed on the separated specimens, so folding blades are integrated into the Punkturnadelzylinder or gripper cylinder, which press the specimens to form transverse folds between jaws of a cooperating with the Punkturnadelzylinder or gripper cylinder jaw cylinder. If no transverse folds are to be formed on the specimens, no folding blades are integrated in the puncturing needle cylinder or gripper cylinder. The separated from the web-shaped substrate and optionally provided with transverse folds copies can be provided in the region of a folding table with second Längsfalzen, which run parallel to the longitudinal fold formed in the former.

Der mit dem Schneidmesserzylinder zusammenwirkende Punkturnadelzylinder oder Greiferzylinder kann zur Bereitstellung einer Sammelfunktion des Falzapparats als sogenannter Sammelzylinder ausgebildet sein. Mit derartigen Sammelzylindern ist es möglich, im Bereich des Sammelzylinders mehrere Exemplare aufeinander zu legen und demnach zu sammeln. Im Sammelbetrieb sowie Nichtsammelbetrieb und gegebenenfalls der Falzmesser des Sammelzylinders ist eine spezielle Ansteuerung der Halteeinrichtung und die Bewegung der Falzmesser des Sammelzylinders erforderlich, wobei das Öffnen und Schließen der Halteeinrichtungen im Sammelbetrieb über mindestens je eine Steuerkurve und mindestens je eine Abdeckkurve des Sammelzylinders gesteuert wird. Im Nichtsammelbetrieb wird das Öffnen und Schließen der Halteeinrichtung und die Bewegung der Falzmesser ausschließlich von den Steuerkurven gesteuert.The cooperating with the cutting blade cylinder dot needle cylinder or gripper cylinder can be designed to provide a collecting function of the folder as a so-called collecting cylinder. With such collecting cylinders, it is possible to place several copies on each other in the area of the collecting cylinder and therefore to collect them. In collective operation and non-collecting operation and optionally the folding blade of the collecting cylinder a special control of the holding device and the movement of the folding blade of the collecting cylinder is required, the opening and closing of the holding devices is controlled in the collecting operation via at least one control cam and at least one cover curve of the collecting cylinder. In non-collection operation, the opening and closing of the holding device and the movement of the folding blade is controlled solely by the control cams.

Ein Sammelzylinder eines Falzapparats einer Druckmaschine mit den Merkmalen des Oberbegriffs des Anspruchs 1 ist aus der DE 38 10 439 C1 bekannt. So umfasst der Sammelzylinder neben mindestens einer Steuerkurve auch mindestens eine Abdeckkurve. Um den Sammelzylinder gemäß der DE 38 10 439 C1 zwischen dem Sammelbetrieb und dem Nichtsammelbetrieb sowie umgekehrt zu überführen, ist die oder jede Abdeckkurve über ein auf einer teilweise als Schnecke ausgebildeten Welle axial verschiebbar gelagertes Hohlritzel antreibbar, wobei der Sammelzylinder durch eine Axialverschiebung des Hohlritzels zwischen dem Sammelbetrieb und dem Nichtsammelbetrieb sowie umgekehrt überführbar bzw. umstellbar ist. Die Schriften EP 1 475 336 A1 und EP 1 069 063 A1 offenbaren ebenfalls Sammelzylinder der vorgenannten Art. Derartige Konstruktionen von Sammelzylindern bewirken eine relativ große Bauform desselben.A collecting cylinder of a folding apparatus of a printing press with the features of the preamble of claim 1 is known from DE 38 10 439 C1 known. Thus, the collecting cylinder also comprises at least one covering curve in addition to at least one control cam. To the collecting cylinder according to the DE 38 10 439 C1 between the collecting operation and the non-collecting operation as well as vice versa, the or each covering curve is drivable via an axially slidably mounted on a partially formed as a worm shaft hollow pinion, wherein the collecting cylinder by an axial displacement of the hollow pinion between the collecting operation and the non-collecting operation and vice versa or is convertible. The writings EP 1 475 336 A1 and EP 1 069 063 A1 also disclose collecting cylinder of the aforementioned type. Such constructions of collecting cylinders cause the same a relatively large size.

Hiervon ausgehend liegt der vorliegenden Erfindung die Aufgabe zugrunde, einen neuartigen Sammelzylinder eines Falzapparats einer Druckmaschine zu schaffen. Diese Aufgabe wird durch einen Sammelzylinder eines Falzapparats gemäß Anspruch 1 gelöst.On this basis, the present invention seeks to provide a novel collecting cylinder of a folding apparatus of a printing press. This object is achieved by a collecting cylinder of a folding apparatus according to claim 1.

Erfindungsgemäß ist der Zylinderkörper des Sammelzylinders zusammen mit der oder jeder Steuerkurve über einen ersten Lagerkörper an einem Gestell gelagert, wobei die oder jede Abdeckkurve über einen zweiten Lagerkörper koaxial zum ersten Lagerkörper auf einer Achse des Sammelzylinders gelagert ist, wobei eine Drehzahldifferenz zwischen der oder jeder Abdeckkurve und dem Sammelzylinder über ein mehrere Zahnräder und eine schaltbare Eindeutigkeitskupplung aufweisendes Übersetzungsgetriebe bereitstellbar ist, und wobei zur Umstellung des Sammelzylinders zwischen dem Nichtsammelbetrieb und dem Sammelbetrieb sowie umgekehrt bei geöffneter Eindeutigkeitskupplung eine ausschließliche Relativverdrehung zwischen der oder jeder Abdeckkurve und dem Sammelzylinder um einen bestimmten Winkel derart realisierbar ist, dass auch die Eindeutigkeitskupplung um diesen Winkel verdrehbar ist.According to the cylinder body of the collecting cylinder is mounted together with the or each control cam via a first bearing body on a frame, wherein the or each cover curve is mounted on a second bearing body coaxial with the first bearing body on an axis of the collecting cylinder, wherein a speed difference between the or each cover curve and to the collecting cylinder via a plurality of gears and a shiftable uniqueness clutch having gear ratio can be provided, and wherein the conversion of the collecting cylinder between the non-collecting and the collecting operation and vice versa with open uniqueness clutch exclusive relative rotation between the or each cover curve and the collecting cylinder by a certain angle so feasible is that the uniqueness clutch is rotatable by this angle.

Beim erfindungsgemäßen Sammelzylinder erfolgt die Überführung desselben zwischen dem Nichtsammelbetrieb und dem Sammelbetrieb sowie umgekehrt ausschließlich über eine Relativverdrehung zwischen der oder jeder Abdeckkurve und dem Sammelzylinder.When collecting cylinder according to the invention, the transfer of the same takes place between the non-collecting operation and the collecting operation and vice versa exclusively via a relative rotation between the or each covering curve and the collecting cylinder.

Es erfolgt im Unterschied zum Stand der Technik gemäß DE 38 10 439 C1 bei der Überführung des Sammelzylinders zwischen dem Nichtsammelbetrieb und dem Sammelbetrieb sowie umgekehrt keine axiale Bewegung von Baugruppen desselben, so dass der erfindungsgemäße Sammelzylinder gegenüber dem Stand der Technik eine kleinere Bauform aufweist. Des Weiteren ist die erfindungsgemäße Ausführung eines Sammelzylinders konstruktiv einfacher und damit kostengünstiger.It is done in contrast to the prior art according to DE 38 10 439 C1 during the transfer of the collecting cylinder between the non-collecting operation and the collecting operation and vice versa no axial movement of assemblies thereof, so that the collecting cylinder according to the invention over the prior art has a smaller design. Furthermore, the inventive design of a collecting cylinder is structurally simpler and therefore less expensive.

Nachfolgend wird die hier vorliegende Erfindung unter Bezugnahme auf Fig. 1 und 2 im größeren Detail beschrieben, wobei Fig. 1 und 2 zwei unterschiedliche Ausführungsbeispiele eines erfindungsgemäßen Sammelzylinders eines Falzapparats einer Druckmaschine zeigen.Hereinafter, the present invention will be described with reference to FIG Fig. 1 and 2 described in greater detail, wherein Fig. 1 and 2 show two different embodiments of a collecting cylinder according to the invention of a folding apparatus of a printing press.

Fig. 1 zeigt einen ausschnittsweisen Querschnitt aus einem Sammelzylinder nach einem ersten Ausführungsbeispiel der Erfindung, wobei der Sammelzylinder der Fig. 1 einen Zylinderkörper 1 aufweist, der über einen Lagerkörper 2 an einem Gestell 3 eines Falzapparats gelagert ist. An diesem Lagerkörper 2 greifen weiterhin Steuerkurven 4 an, über die in einem Nichtsammelbetrieb des Sammelzylinders dem Zylinderkörper 1 zugeordnete, an Wellen 5 befestigte Halteeinrichtungen, die vorzugsweise als Punkturnadeln oder Greifer ausgebildet sind, ansteuerbar sind. Fig. 1 shows a partial cross section of a collecting cylinder according to a first embodiment of the invention, wherein the collecting cylinder of Fig. 1 a cylinder body 1 which is mounted on a bearing body 2 on a frame 3 of a folding apparatus. Control cams 4 continue to engage on this bearing body 2, via which in a non-collecting operation of the collecting cylinder associated with the cylinder body 1, fixed to shafts 5 holding devices, which are preferably designed as puncture needles or grippers, are controllable.

Im Sammelbetrieb des Sammelzylinders wirken diese Steuerkurven 4 mit Abdeckkurven 6 zusammen, die einem zweiten Lagerkörper 7 zugeordnet sind. Der zweite Lagerkörper 7 erstreckt sich koaxial zum ersten Lagerkörper 2 und ist über Lager 21 auf einer Achse 23 des Sammelzylinders drehbar gelagert. Weiterhin ist der zweite Lagerkörper 7 über Lager 22 gegenüber dem ersten Lagerkörper 2 drehbar gelagert, wobei gemäß Fig. 1 der zweite Lagerkörper 7 einen Abschnitt der Achse 23 des Sammelzylinders umschließt und der erste Lagerkörper 2 den zweiten Lagerkörper 7 abschnittsweise umschließt.In collective operation of the collecting cylinder, these control cams 4 cooperate with covering curves 6, which are assigned to a second bearing body 7. The second bearing body 7 extends coaxially with the first bearing body 2 and is rotatably supported by bearings 21 on an axis 23 of the collecting cylinder. Furthermore, the second bearing body 7 is rotatably supported by bearings 22 relative to the first bearing body 2, wherein according to Fig. 1 the second bearing body 7 encloses a portion of the axis 23 of the collecting cylinder and the first bearing body 2 surrounds the second bearing body 7 in sections.

Wie bereits ausgeführt, werden die dem Zylinderkörper 1 zugeordneten, an den Wellen 5 befestigten Halteeinrichtungen des Sammelzylinders im Nichtsammelbetrieb ausschließlich von den Steuerkurven 4 und im Sammelbetrieb sowohl von den Steuerkurven 4 als auch von den Abdeckkurven 6 angesteuert, wobei dann eine definierte Differenzdrehzahl zwischen dem Sammelzylinder und den Abdeckkurven 6 erforderlich ist. Diese Differenzdrehzahl wird über ein mehrere Zahnräder 8, 9, 10 und 11 aufweisendes Übersetzungsgetriebe bereitgestellt. Gemäß Fig. 1 sind die Zahnräder 8 und 9 der Achse 23 des Sammelzylinders zugeordnet, die Zahnräder 10 und 11 sind hingegen einer achsparallel zur Achse 23 verlaufenden Welle 12 zugeordnet, der weiterhin eine schaltbare Eindeutigkeitskupplung 13 zugeordnet ist. Die Zahnräder 8 und 11 kämmen ineinander und bilden ein erstes Zahnradpaar, ebenso kämmen die Zahnräder 9 und 10 ineinander und bilden ein zweites Zahnradpaar. Das erste, von den Zahnrädern 8 und 11 gebildete Zahnradpaar verfügt über ein Übersetzungsverhältnis von 1:1. Das von den Zahnrädern 9 und 10 gebildete, zweite Zahnradpaar verfügt hingegen über ein Übersetzungsverhältnis, mit welchem die im Sammelbetrieb benötigte Differenzdrehzahl zwischen dem Sammelzylinder und den Abdeckkurven 6 des Sammelzylinders bereitgestellt werden kann.As already stated, the cylinders of the body 1 associated, attached to the shafts 5 holding means of the collecting cylinder are driven in the non-collecting mode exclusively by the cams 4 and in collective operation both from the cams 4 and the cover curves 6, in which case a defined differential speed between the collecting cylinder and the capping curves 6 is required. This differential speed is provided via a plurality of gears 8, 9, 10 and 11 exhibiting transmission gear. According to Fig. 1 the gears 8 and 9 are associated with the axis 23 of the collecting cylinder, the gears 10 and 11, however, are associated with an axis-parallel to the axis 23 extending shaft 12, which is further associated with a switchable uniqueness clutch 13. The gears 8 and 11 mesh with each other and form a first gear pair, as well as the gears mesh 9 and 10 into each other and form a second gear pair. The first gear pair formed by the gears 8 and 11 has a gear ratio of 1: 1. The second gear pair formed by the gears 9 and 10, however, has a gear ratio with which the differential speed required in the collecting operation between the collecting cylinder and the capping curves 6 of the collecting cylinder can be provided.

Gemäß Fig. 1 ist das Zahnrad 8 des ersten Zylinderpaars auf der Achse 23 des Sammelzylinders frei drehbar gelagert. Das Zahnrad 11 des ersten Zylinderpaars ist hingegen auf der Welle 12 fixiert. Das Zahnrad 9 des zweiten Zylinderpaars ist auf der Welle 23 des Sammelzylinders fixiert. Das Zahnrad 10 des zweiten Zylinderpaars ist prinzipiell auf der Welle 12 frei drehbar gelagert, kann jedoch über die Eindeutigkeitskupplung 13 an die Welle fixiert werden. Das der Achse 23 zugeordnete Zahnrad 8 des ersten Zylinderpaars ist demnach als sogenanntes Losrad ausgeführt, welches gegenüber der Achse 23 verdreht werden kann. Die Welle 12, welche die Zahnräder 10 und 11 trägt, ist einerseits im Gestell 3 und andererseits in einem Hilfsgestell 24 drehbar gelagert. Über die der Welle 12 zugeordnete Eindeutigkeitskupplung 13 kann eine Kraftübertragung zwischen den Zahnrädern 10 und 11 bereitgestellt oder auch unterbrochen werden.According to Fig. 1 the gear 8 of the first pair of cylinders is freely rotatably mounted on the axis 23 of the collecting cylinder. The gear 11 of the first pair of cylinders, however, is fixed on the shaft 12. The gear 9 of the second pair of cylinders is fixed on the shaft 23 of the collecting cylinder. The gear 10 of the second pair of cylinders is in principle freely rotatably mounted on the shaft 12, but can be fixed on the uniqueness clutch 13 to the shaft. The axle 23 associated gear 8 of the first pair of cylinders is therefore designed as a so-called idler gear, which can be rotated relative to the axis 23. The shaft 12, which carries the gears 10 and 11, is rotatably mounted on the one hand in the frame 3 and on the other hand in an auxiliary frame 24. About the shaft 12 associated uniqueness clutch 13, a power transmission between the gears 10 and 11 can be provided or interrupted.

Dann, wenn über die Eindeutigkeitskupplung 13 die Kraftübertragung zwischen den beiden Zahnrädern 10 und 11 bereitgestellt wird, drehen beide Zahnräder 10 und 11 mit der gleichen Drehzahl zusammen mit der Welle 12. Dann hingegen, wenn die Eindeutigkeitskupplung 13 die Kraftübertragung zwischen den Zahnrädern 10 und 11 unterbricht, ist das Zahnrad 10 im Sinne eines Losrads unabhängig vom Zahnrad 11 sowie von der Welle 12 verdrehbar.Then, when the power transmission between the two gears 10 and 11 is provided via the uniqueness clutch 13, both gears 10 and 11 rotate at the same speed together with the shaft 12. Then, however, when the uniqueness clutch 13, the power transmission between the gears 10 and 11th interrupts, the gear 10 in the sense of a loose wheel regardless of the gear 11 and the shaft 12 is rotatable.

Zur Umstellung des in Fig. 1 dargestellten Sammelzylinders zwischen dem Sammelbetrieb und dem Nichtsammelbetrieb sowie umgekehrt ist bei geöffneter Eindeutigkeitskupplung 13 eine ausschließliche Relativverdrehung zwischen den Abdeckkurven 6 und dem Sammelzylinder um einen bestimmten Winkel realisierbar, wobei auch die Eindeutigkeitskupplung 13 um diesen Winkel verdrehbar ist.To convert the in Fig. 1 illustrated collecting cylinder between the collecting operation and the non-collecting operation and vice versa is an unrelated Relativverdrehung between the Abdeckkurven 6 and the collecting cylinder can be realized by a certain angle with open uniqueness clutch 13, whereby the uniqueness clutch 13 is rotated by this angle.

Wie bereits ausgeführt, unterbricht bei geöffneter Eindeutigkeitskupplung 13 dieselbe die Kraftübertragung zwischen den der Welle 12 zugeordneten Zahnrädern 10 und 11, so dass bei Stillstand eines Hauptantriebs des Falzapparats ein separater Antrieb 17 die Abdeckkurven 6 gegenüber dem Sammelzylinder verdrehen kann. Hierzu treibt der separate Antrieb 17 über ein auf einer weiteren achsparallel zur Achse 23 des Sammelzylinders verlaufenden Welle 14 gelagertes Zahnrad 15 sowie über einen derselben Welle 14 zugeordneten, gesperrten Freilauf 16 in das Zahnrad 8 des ersten Zylinderpaars ein, wobei hierdurch der zweite Lagerkörper 7, der mit dem Zahnrad 8 fest verbunden ist, verdreht wird. Da, wie bereits ausgeführt, an diesem zweiten Lagerkörper 7 die Abdeckkurven 6 angreifen, werden hierdurch die Abdeckkurven 6 relativ zu dem Sammelzylinder verdreht. Da das Zahnrad 8 mit dem Zahnrad 11 in Eingriff steht und das Übersetzungsverhältnis zwischen den Zahnrädern 8 und 11 1:1 beträgt, wird bei Verdrehung der Abdeckkurven 6 um einen definierten Winkel auch die Eindeutigkeitskupplung 13 um diesen definierten Winkel verdreht. Die Zahnräder 9 und 10 stehen hingegen bei geöffneter Eindeutigkeitskupplung still. Das Zahnrad 15 ist drehmomentensteif mit dem Freilauf 16 verbunden. Der Antrieb 17 ist drehmomentensteif mit der Welle 14 verbunden.As already stated, interrupts open unambiguity clutch 13 the same power transmission between the shaft 12 associated gears 10 and 11, so that at standstill of a main drive of the folder, a separate drive 17, the cover curves 6 can rotate relative to the collecting cylinder. For this purpose, the separate drive 17 drives a toothed wheel 15 mounted on a further shaft axis parallel to the axis 23 of the collecting cylinder 14 and a locked freewheel 16 assigned to the same shaft 14 in the gear 8 of the first pair of cylinders, whereby the second bearing body 7, which is fixedly connected to the gear 8, is rotated. Since, as already stated, engage the cover curves 6 at this second bearing body 7, thereby the covering curves 6 are rotated relative to the collecting cylinder. Since the gear 8 is in engagement with the gear 11 and the gear ratio between the gears 8 and 11 1: 1, is rotated when twisting the Abdeckkurven 6 by a defined angle and the uniqueness clutch 13 by this defined angle. The gears 9 and 10, however, stand still with open uniqueness clutch. The gear 15 is torsionally stiff connected to the freewheel 16. The drive 17 is torsionally stiff connected to the shaft 14.

Die Eindeutigkeitskupplung 13 verfügt über mehrere Schaltpunkte, die jeweils um einen definierten Winkel zueinander versetzt sind. Ein Schließen der Eindeutigkeitskupplung 13 ist nur dann möglich, wenn entsprechende Kupplungsscheiben der Eindeutigkeitskupplung 13 um den jeweiligen Winkel zueinander verdreht wurden. Fig. 1 zeigt eine dem Zahnrad 10 zugeordnete Kupplungsscheibe 18. Bei einem drei Abschnittslängen großen Sammelzylinder und einem Übersetzungsverhältnis zwischen den Abdeckkurven 6 und den Steuerkurven 4 von ¾, beträgt ein Umschaltwinkel von Sammelbetrieb zu Nichtsammelbetrieb 45° und von Nichtsammelbetrieb zu Sammelbetrieb 135°. Damit lassen sich dann für die Eindeutigkeitskupplung 13 vier Schaltpunkte realisieren.The uniqueness clutch 13 has a plurality of switching points, which are each offset by a defined angle to each other. Closing the uniqueness clutch 13 is only possible if corresponding clutch discs of the uniqueness clutch 13 have been rotated by the respective angle to each other. Fig. 1 shows a gear wheel 10 associated with the clutch plate 18. In a three-section-length collecting cylinder and a transmission ratio between the capping curves 6 and the cams 4 of ¾, a switching angle of collection to non-collection mode is 45 ° and from non-collection to collection operation 135 °. This can then be realized for the uniqueness clutch 13 four switching points.

Beim erfindungsgemäßen Sammelzylinder 1 erfolgt eine Umstellung zwischen Sammelproduktion und Nichtsammelproduktion sowie umgekehrt demnach ausschließlich über eine Relativverdrehung zwischen den Abdeckkurven 6 und dem Sammelzylinder. Es ist keine axiale Bewegung von Baugruppen des Sammelzylinders bei dieser Umstellung erforderlich. Durch die koaxiale Lagerung des die Abdeckkurven 6 tragenden Lagerkörpers 7 und des die Steuerkurven 4 tragenden Lagerkörpers 2 erfolgt ein Splitting der Lagerdrehzahlen, wobei das Lager 21 zwischen der Achse 23 des Sammelzylinders und dem Lagerkörper 7 der Differenzdrehzahl zwischen der Drehzahl der Abdeckkurven 6 und dem Sammelzylinder ausgesetzt ist, und wobei das Lager 22 zwischen den beiden Lagerkörpern 2, 7 der Drehzahl der Abdeckkurven 6 ausgesetzt ist.When collecting cylinder 1 according to the invention, there is a change between collective production and non-collection production and vice versa therefore exclusively via a relative rotation between the Abdeckkurven 6 and the collecting cylinder. There is no axial movement of assemblies of the collecting cylinder in this conversion required. Due to the coaxial bearing of the cover curves 6 bearing bearing body 7 and the cams 4 bearing bearing body 2, a splitting of the bearing speeds, wherein the bearing 21 between the axis 23 of the collecting cylinder and the bearing body 7 of the differential speed between the speed of the capping curves 6 and the collecting cylinder is exposed, and wherein the bearing 22 between the two bearing bodies 2, 7 of the rotational speed of the Abdeckkurven 6 is exposed.

Im Ausführungsbeispiel der Fig. 1 erfolgt die Umstellung des Sammelzylinders zwischen dem Sammelbetrieb und dem Nichtsammelbetrieb über einen separaten Antrieb 17, der bei geöffneter Eindeutigkeitskupplung 13 über einen gesperrten Freilauf 16 und ein mit dem Freilauf 16 drehmomentensteif verbundenes Zahnrad 15 die Abdeckkurven 6 sowie den durch die Eindeutigkeitskupplung 13 vom Hauptantrieb des Falzantriebs getrennten Teil des Übersetzungsgetriebes um einen definierten Winkel verdreht, wobei auch die Eindeutigkeitskupplung 13 um diesen Winkel verdreht wird.In the embodiment of Fig. 1 the conversion of the collecting cylinder between the collecting operation and the non-collecting operation via a separate drive 17, the cover cam 6 and the uniqueness clutch 13 from the main drive of the folding drive with open uniqueness clutch 13 via a locked freewheel 16 and a freewheel 16 torque-connected gear 15 separated part of the transmission gear rotated by a defined angle, wherein the uniqueness clutch 13 is rotated by this angle.

Fig. 2 zeigt ein zweites Ausführungsbeispiel eines erfindungsgemäßen Sammelzylinders eines Falzapparats einer Druckmaschine, wobei der prinzipielle Aufbau des Sammelzylinders der Fig. 2 dem Ausführungsbeispiel der Fig. 1 entspricht, so dass zur Vermeidung unnötiger Wiederholungen für gleiche Baugruppen gleiche Bezugsziffern verwendet werden. Nachfolgend wird nur auf die Details eingegangen, durch die sich das Ausführungsbeispiel der Fig. 2 vom Ausführungsbeispiel der Fig. 1 unterscheidet. Fig. 2 shows a second embodiment of a collecting cylinder according to the invention of a folding apparatus of a printing machine, wherein the basic structure of the collecting cylinder of the Fig. 2 the embodiment of the Fig. 1 is the same, so that the same reference numerals are used to avoid unnecessary repetition for the same modules. In the following, only the details are dealt with by which the embodiment of the Fig. 2 from the embodiment of Fig. 1 different.

Im Ausführungsbeispiel der Fig. 2 ist zur Bereitstellung der Relativverdrehung zwischen den Abdeckkurven 6 und dem Sammelzylinder kein separater Antrieb erforderlich, so dass beim Ausführungsbeispiel der Fig. 2 die Baugruppen 14, 15, 16 und 17 entfallen.In the embodiment of Fig. 2 is to provide the relative rotation between the Abdeckkurven 6 and the collecting cylinder no separate drive required, so that in the embodiment of Fig. 2 the assemblies 14, 15, 16 and 17 omitted.

Vielmehr wird beim Ausführungsbeispiel der Fig. 2 die ausschließliche Relativverdrehung zwischen den Abdeckkurven 6 und dem Sammelzylinder dadurch bereitgestellt, dass dem Zahnrad 11 des ersten Zahnradpaars eine Bremsscheibe 19 zugeordnet ist, die mit einer Bremse 20 derart zusammenwirkt, dass zur Umstellung des Sammelzylinders zwischen dem Nichtsammelbetrieb und dem Sammelbetrieb sowie umgekehrt bei geöffneter Eindeutigkeitskupplung 13 und demnach bei unterbrochener Kraftübertragung zwischen den Zahnrädern 10 und 11 die Bremse 20 geschlossen ist. Bei geöffneter Eindeutigkeitskupplung 13 und geschlossener Bremse 20 bleiben die Zahnräder 11 und 8 des ersten Zahnradpaars dann, wenn der Hauptantrieb des Falzapparats mit einer relativ geringen Drehzahl dreht, stehen. Bedingt hierdurch bleiben auch die dem zweiten Lagerkörper 7 zugeordneten Abdeckscheiben 6 stehen, da der Lagerkörper 7 mit dem Zahnrad 8 des ersten Zahnradpaars fest verbunden ist. Demgegenüber können jedoch bei geöffneter Eindeutigkeitskupplung 13 und geschlossener Bremse 20 der Sammelzylinder gegenüber den Abdeckkurven 6 verdreht werden, wobei auch die Eindeutigkeitskupplung 13 entsprechend verdreht wird.Rather, in the embodiment of the Fig. 2 the exclusive relative rotation between the Abdeckkurven 6 and the collecting cylinder provided by the fact that the gear 11 of the first gear pair is associated with a brake disc 19 which cooperates with a brake 20 such that the conversion of the collecting cylinder between the non-collecting and the collecting operation and vice versa with open uniqueness clutch 13 and thus with interrupted power transmission between the gears 10 and 11, the brake 20 is closed. With open uniqueness clutch 13 and brake 20 closed, the gears 11 and 8 of the first pair of gears remain when the main drive of the folder rotates at a relatively low speed stand. Due to this, the cover bearing plates 6 associated with the second bearing body 7 also remain, since the bearing body 7 is fixedly connected to the gearwheel 8 of the first gearwheel pair. In contrast, however, with the uniqueness clutch 13 open and the brake 20 closed, the collecting cylinder can be rotated relative to the covering curves 6, with the uniqueness clutch 13 also being correspondingly rotated.

Um hierbei eine winkelgleiche Verdrehung von Abdeckkurve 6 und Eindeutigkeitskupplung 13 zu gewährleisten, beträgt im Ausführungsbeispiel der Fig. 2 das Übersetzungsverhältnis zwischen den ineinander kämmenden Zahnrädern 9 und 10 des zweiten Zahnradpaars 1:1, wohingegen das Übersetzungsverhältnis zwischen den Zahnrädern 8 und 11 des ersten Zahnradpaars die im Sammelbetrieb benötigte Drehzahldifferenz zwischen dem Sammelzylinder und Abdeckkurven 6 bereitstellt.In order to ensure an equal angle rotation of cover curve 6 and uniqueness clutch 13, in the embodiment of the Fig. 2 the gear ratio between the intermeshing gears 9 and 10 of the second gear pair 1: 1, whereas the gear ratio between the gears 8 and 11 of the first gear pair provides the required speed difference between the collecting cylinder and cover curves 6 in the collection operation.

Nach ausgeführter Umstellung des Sammelzylinders zwischen dem Sammelbetrieb und dem Nichtsammelbetrieb bzw. umgekehrt zwischen dem Sammelbetrieb und dem Nichtsammelbetrieb wird die Eindeutigkeitskupplung 13 geschlossen und die Bremse 20 geöffnet. Der Vorteil des Ausführungsbeispiels der Fig. 2 gegenüber dem Ausführungsbeispiel der Fig. 1 besteht darin, dass beim Ausführungsbeispiel der Fig. 2 kein separater Antrieb benötigt wird, um die Relativverdrehung zwischen Abdeckkurven 6 und dem Sammelzylinder zu gewährleisten.After completed conversion of the collecting cylinder between the collecting operation and the non-collecting operation or vice versa between the collecting operation and the non-collecting operation, the uniqueness clutch 13 is closed and the brake 20 is opened. The advantage of the embodiment of Fig. 2 compared to the embodiment of the Fig. 1 is that in the embodiment of Fig. 2 no separate drive is needed to ensure relative rotation between cover curves 6 and the collector cylinder.
