Abstract

The invention relates to a device for changing over from collecting operation to non-collecting operation on a cutting/collecting cylinder (4) of a folding apparatus for rotary printing machines, which can be changed over from collecting operation to non-collecting operation and vice versa. At least one row of puncture needles (7) is accommodated in the cutting/collecting cylinder (4), it being possible for the mounting shaft (9) of said puncture needles to be activated via a cam roller (41) which rolls in a cam body (27). The cam body (27) is accommodated adjustably in the housing (25) of the folding apparatus such that it is located opposite an end side of the cutting/collecting cylinder (4). The invention is distinguished in that the circumferential-speed ratio of cutting/collecting cylinder (4) to cam body (27) can be changed by a coaxially movable, second force-transmission element (34) which passes through a first force-transmission element (29) with at least two force-introduction points (29a, 29b). <IMAGE>

Description

Die Erfindung betrifft eine Vorrichtung zum Umstellen von Sammel- auf Nichtsammelbetrieb an einem Schneid-/Sammelzylinder eines Falzapparates für Rotationsdruckmaschinen, welcher von Sammelbetrieb auf Nicht-Sammelbetrieb und umgekehrt umsteilbar ist und in welchem mindestens eine Reihe von Punkturen aufgenommen ist, deren Lagerungswelle über eine Kurvenrolle aktivierbar ist, die an einem Kurvenkörper abrollt, der einer Stirnseite des Schneid-/Sammelzylinders gegenüberliegend am Gehäuse des Falzapparates verstellbar aufgenommen ist.The invention relates to a device for converting from collecting to non-collecting operation on a cutting / collecting cylinder of a folder for rotary printing presses, which can be switched from collecting operation to non-collecting operation and vice versa and in which at least a number of punctures are received, the bearing shaft of which via a cam roller can be activated, which rolls on a cam body, which is adjustably received on the housing of the folder opposite an end face of the cutting / collecting cylinder.

Aus dem Stand der Technik, JP-A-63 185 777 ist ein Falzapparat für eine Rotationsdruckmaschine bekannt. Durch eine aufsteckbare Handkurbel ist eine Welle verdrehbar, auf welcher mehrere Kupplungen angeordnet sind. Eine dieser Kupplungen wird ausgerückt, wonach durch Betätigen der Handkurbel die Phasenlage einer Steuerkurve veränderbar ist. Nach erfolgter Verstellung wird besagte Kupplung wieder eingerückt. Bei dieser Vorrichtung erfolgt ein sammeln von Exemplaren auf einem separaten Sammelzylinder, der nicht gleichzeitig eine Schneidfunktion übernimmt.A folder for a rotary printing press is known from the prior art, JP-A-63 185 777. A shaft, on which several couplings are arranged, can be rotated by means of an attachable hand crank. One of these clutches is disengaged, after which the phase position of a control curve can be changed by actuating the hand crank. After the adjustment has been made, the clutch is engaged again. In this device, specimens are collected on a separate collecting cylinder, which does not simultaneously perform a cutting function.

Ein weiterer aus dem Stand der Technik bekannter Falzapparat gemäß DE 38 28 372 A1 umfaßt einen mehrfachgroßen Sammelzylinder. In diesem sind mehrere Betätigungseinrichtungen aufgenommen, die an ihren zwei Steuerkurven zugewandten Enden je zwei auf einer gemeinsamen Achse nebeneinander angeordnete Tastrollen aufweisen.Another folding device known from the prior art according to DE 38 28 372 A1 comprises a multi-sized collecting cylinder. A plurality of actuating devices are accommodated in this, each of which has two sensing rollers arranged next to one another on a common axis at their ends facing two control cams.

Zwischen den beiden bezogen auf den Sammelzylinder stillstehenden Steuerkurven ist ein Nockenträger angeordnet, welcher mehrere Nocken aufnimmt, die in eine Aktiv- und eine Passivstellung bringbar sind. In Aktivstellung der Nocken hindern diese durch ein Abstützen einer der beiden Tastrollen einer jeden Betätigungseinrichtung, daß ein Falzvorgang ausgeführt wird. In Passivstellung der Nocken hingegen, können die Tastrollen den Steuersenken der jeweiligen Steuerkurve folgen und Falz- bzw. Punkturvorgänge auslösen. Der aus den Figuren der DE 38 28 372 A1 hervorgehende große apparative Aufwand ist jedoch nur bei Großtiefdruckmaschinen gerechtfertigt, die bis zu acht Ätzungen am Umfang eines Druckwerkzylinders aufweisen können. Bei kleineren Falzapparaten ist der mechanische Aufwand nicht vertretbar.Between the two control cams which are stationary with respect to the collecting cylinder, a cam carrier is arranged which receives several cams which can be brought into an active and a passive position. In the active position of the cams, by supporting one of the two sensing rollers of each actuating device, they prevent a folding process from being carried out. In the passive position of the cams, on the other hand, the feeler rollers can follow the control depressions of the respective control cam and trigger folding or puncturing processes. However, the large amount of equipment required from the figures in DE 38 28 372 A1 is only justified in large intaglio printing machines, which can have up to eight etchings on the circumference of a printing unit cylinder. The mechanical effort is not justifiable in the case of smaller folders.

US-PS 3,865,361 offenbart einen Falzzylinder, an dessen Stirnseite eine Kurve aufgenommen ist, in welche mehrere Laufflächen aufgenommen sind. In diesen Laufflächen rollen nebeneinander angeordnete Rollen ab und bewegen Punkturenwellen entsprechend. Ein Umstellung am Falzzylinder vom Betriebsmodus Sammeln auf den Betriebsmodus Nicht-Sammeln erfolgt durch axiales Verschieben der Kurve am gemeinsamen Hochpunkt der Laufflächen. Aus Kostengründen gilt es heute, die Fertigung von Kurven mit unterschiedlichen Laufflächen, die zudem unterschiedlich gehärtet werden müssen, möglichst zu vermeiden. Die axiale Verschiebbarkeit einer eine Kurve aufnehmenden Konstruktion birgt die Gefahr, daß durch sich während des Betriebes einstellendes Spiel die Verkantungsgefahr der auf der Welle aufgenommenen Konstruktion ständig zunimmt. Dies macht die Verwendung einer verschiebbaren Kurve zumindest problematisch.US Pat. No. 3,865,361 discloses a folding cylinder, on the end face of which a curve is recorded, in which a plurality of running surfaces are recorded. Rollers arranged next to each other roll in these treads and move puncture waves accordingly. A changeover on the folding cylinder from the collecting operating mode to the non-collecting operating mode takes place by axially shifting the curve at the common high point of the running surfaces. For cost reasons, it is important to avoid the production of curves with different treads, which also have to be hardened differently, as far as possible. The axial displaceability of a structure that takes up a curve carries the risk that the risk of canting of the structure accommodated on the shaft increases constantly due to play occurring during operation. This makes the use of a displaceable curve at least problematic.

DE 17 61 134 schließlich offenbart eine von Einfachbetrieb auf Sammelbetrieb umstellbare Falzvorrichtung für Rotationsdruckmaschinen mit einem angetriebenen Falzzylinder. Bei dieser Konfiguration sind in eine als Schleife ausgebildete Kurvennut einer Steuerscheibe mehrere an der diametral gegenüberliegende nach innen gerichtete Kurvenvorsprünge eingelassen. Ferner ist ein Zahnradschaltgetriebe vorgesehen, mit welchem das Drehzahlverhältnis der Drehzahl der Steuerscheibe in Bezug auf die Drehzahl des Falzzylinders einstellbar ist. Der entscheidende Nachteil dieser Falzvorrichtung liegt in der raumgreifenden Dimensionierung des Zahnradschaltgetriebes, welches eine unvertretbar hohe Anzahl geradverzahnter Zahnräder umfaßt, die die Fertigungskosten negativ beeinflussen.Finally, DE 17 61 134 discloses a folding device for rotary printing machines with a driven folding cylinder that can be converted from simple operation to collective operation. This configuration is in a loop trained cam groove of a control disc embedded in the diametrically opposite inward projections. Furthermore, a gearwheel transmission is provided, with which the speed ratio of the speed of the control disk in relation to the speed of the folding cylinder can be adjusted. The decisive disadvantage of this folding device lies in the extensive dimensioning of the gear transmission, which includes an unacceptably high number of straight toothed gears, which negatively influence the manufacturing costs.

Ausgehend von den skizzierten Konstruktionen des Standes der Technik, liegt der Erfindung die Aufgabe zugrunde, eine Vorrichtung zum Umstellen von Sammel- auf Nichtsammelbetrieb an Schneid-/Sammelzylindern so zu verbessern, daß auf minimalem Bauraum mit wenigen Komponenten eine hohe Betriebssicherheit gewährleistet ist.Based on the outlined constructions of the prior art, the object of the invention is to improve a device for converting from collecting to non-collecting operation on cutting / collecting cylinders in such a way that a high degree of operational safety is ensured in a minimal installation space with few components.

Erfindungsgemäß wird diese Aufgabe gemäß den Merkmalen des Patentanspruches 1 gelöst.According to the invention this object is achieved according to the features of claim 1.

Bei der erfindungsgemäßen Lösung ist von besonderem Vorteil, daß durch ineinander geschachtelte Anordnung der Kraftübertragungselemente eine kompakte Einheit geschaffen werden konnte, bei der lediglich ein Kraftübertragungselement eine axiale Verschiebung erfährt. Dadurch lassen sich der mechanische Aufwand äußerst gering und die Bauraumanforderungen sehr niedrig halten.In the solution according to the invention, it is particularly advantageous that a nested arrangement of the power transmission elements enables a compact unit to be created in which only one power transmission element is axially displaced. This means that the mechanical outlay is extremely low and the space requirements are kept very low.

In weiterführender Ausgestaltung des der Erfindung zugrunde liegenden Gedankens ist vorgesehen, das zweite Kraftübertragungselement auf einem Wellenfortsatz des Schneid-/Sammelzylinders axial verschiebbar zu gestalten. Daneben umfaßt das erste Kraftübertragungselement eine erste Krafteinleitungsstelle, die als Außenverzahnung ausgebildet ist. Außerdem ist im ersten Kraftübertragungselement eine zweite Krafteinleitungsstelle als Innenverzahnung ausgeführt. Da der Kurvenkörper am ersten Kraftübertragungselement befestigt ist, kann über dieses eine Rotationsbewegung in den Kurvenkörper eingeleitet werden. Dazu ist das erste Kraftübertragungselement in Lagern einer Seitenwandbuchse drehbar aufgenommen und gleichzeitig auf einem Lager am Wellenfortsatz aufgenommen. Dadurch ist eine stabile Dreipunktlagerung verwirklicht, die zur Folge hat, daß mechanische Belastungsspitzen sicher aufgenommen werden können. Die Dreipunktlagerung verhindert zudem ein Kippen des ersten Kraftübertragungselementes bezogen auf seine Querachse am Wellenfortsatz.In a further embodiment of the idea on which the invention is based, it is provided that the second force transmission element is designed to be axially displaceable on a shaft extension of the cutting / collecting cylinder. In addition, the first force transmission element comprises a first force introduction point, which is designed as an external toothing is. In addition, a second force introduction point is designed as an internal toothing in the first force transmission element. Since the cam body is attached to the first force transmission element, a rotational movement can be introduced into the cam body via this. For this purpose, the first power transmission element is rotatably received in bearings in a side wall bushing and at the same time received on a bearing on the shaft extension. As a result, a stable three-point bearing is realized, which means that mechanical load peaks can be safely absorbed. The three-point bearing also prevents the first power transmission element from tilting with respect to its transverse axis on the shaft extension.

Parallel zum Wellenfortsatz ist in einer Seitenwandbuchse eine Stummelwelle gelagert, an welcher ein erste und ein zweite miteinander verbundene Verzahnung aufgenommen sind. Das zweite Kraftübertragungselement ist mit der ersten Verzahnung in Eingriff bringbar, wodurch die zweite Verzahnung den Antrieb in die Außenverzahnung des ersten Kraftübertragungselementes eingeleitet wird. In dieser Betriebsstellung wird eine Untersetzung der Drehzahl des Kurvenkörpers zur Drehzahl des Schneid-/Sammelzylinders von 1:2 erreicht. Demnach rotiert der Kurvenkörper nur halb so schnell wie der Schneid-/Sammelzylinder, so daß dessen Lagerungswelle der Punkturen nur bei jeder zweiten Umdrehung des Schneid-/Sammelzylinders aktiviert wird.Parallel to the shaft extension, a stub shaft is mounted in a side wall bushing, on which a first and a second interconnected toothing are received. The second force transmission element can be brought into engagement with the first toothing, as a result of which the second toothing initiates the drive into the external toothing of the first force transmission element. In this operating position, the speed of the cam body is reduced to 1: 2 by the speed of the cutting / collecting cylinder. Accordingly, the cam body rotates only half as fast as the cutting / collecting cylinder, so that its bearing shaft of the punctures is activated only every second rotation of the cutting / collecting cylinder.

Ist das zweite Kraftübertragungselement hingegen mit der Innenverzahnung des ersten Kraftübertragungselementes in Eingriff gebracht, rotieren der Kurvenkörper und die Umfangsfläche des Schneid-/Sammelzylinders mit gleicher Geschwindigkeit. Sind zuvor die auf der Mantelfläche des Schneid-/Sammelzylinders angebrachte Markierung und die gehäusefeste Markierung in Übereinstimmung gebracht worden und wird danach der Zahneingriff hergestellt, verbleiben die Punkturen während der Rotation des Zylinders in ihrer eingefahrenen Position; der besagte Zylinder fungiert dann lediglich als Schneidzylinder.If, on the other hand, the second force transmission element is brought into engagement with the internal toothing of the first force transmission element, the cam body and the peripheral surface of the cutting / collecting cylinder rotate at the same speed. If the marking made on the outer surface of the cutting / collecting cylinder and the housing-fixed marking have been brought into agreement and the tooth engagement is then made, they remain Punctures during the rotation of the cylinder in its retracted position; the said cylinder then only functions as a cutting cylinder.

An der Stellachse der Sammelvorrichtung sind den Betriebspositionen des zweiten Kraftübertragungselementes entsprechende Rastnuten ausgeführt, um das zweite Kraftübertragungselement in seinen Arbeitspositionen zu verriegeln.On the actuating axis of the collecting device, the operating positions of the second power transmission element are designed with locking grooves in order to lock the second power transmission element in its working positions.

The longitudinally folded material web is then pressed between pulling rollers 3 and from there passes into a cylinder gap 19 which is formed between the peripheral surfaces of a cutting / collecting cylinder 4 and a folding cylinder 5. The folding cylinder 5 rotates clockwise, the cutting / collecting cylinder 4 counterclockwise; both cylinders have the same peripheral speed, the diameter of the folding cylinder 5 and the cutting / collecting cylinder 4 behaving as 2: 1.

Der Schneid-/Sammelzylinder 4 ist auf seinem Umfang einerseits mit einem Schneidmesser 6 versehen, während andererseits in unmittelbarer Nähe zum Schneidmesser 6 Punkturen 7 in die Mantelfläche des Schneid-/Sammelzylinders 4 eingelassen sind. Die Punkturen 7 bestehen aus nebeneinander angeordneten Punkturenstangen 21, die mittels Punkturenhebeln 8 an einer Lagerungswelle 9 aufgenommen sind. Der Falzzylinder 5 hingegen, in doppeltem Durchmesser ausgeführt, ist miteinander gegenüberliegenden Falzmesserwellen 10 ausgerüstet, die jeweils ein Falzmesser 11 aufnehmen. Um etwa 90o am Umfang des Falzzylinders 1 versetzt, sind Messerbalken 12 aus Kautschuk und zwei Punkturenreihen 13 aufgenommen. Diese wiederum befinden sich an den Enden von Punkturenhebeln 14, die ihrerseits an Punkturenwellen 15 gelagert sind.The cutting / collecting cylinder 4 is provided on the one hand with a cutting knife 6 on its circumference, while on the other hand 6 punctures 7 are embedded in the outer surface of the cutting / collecting cylinder 4 in the immediate vicinity of the cutting knife. The punctures 7 consist of puncture rods 21 arranged next to one another, which are received on a bearing shaft 9 by means of puncture levers 8. The folding cylinder 5, on the other hand, with a double diameter, is equipped with folding knife shafts 10 located opposite one another, each of which accommodates a folding knife 11. Offset about 90 o on the circumference of the folding cylinder 1, cutter bars 12 made of rubber and two rows of punctures 13 are added. These in turn are located at the ends of puncture levers 14, which in turn are mounted on puncture shafts 15.

Unterhalb des Falzzylinders 5 befindet sich ein Paar Falzwalzen 16, zwischen die - je nach Betriebsmodus des Falzapparates - einzelne Exemplare oder übereinanderliegende Exemplare durch die Falzmesser 11 eingestoßen werden. Die auf diese Art quergefalzten Produkte werden über ein Schaufelrad 17 auf einem Auslageband 18 ausgelegt.Below the folding cylinder 5 there is a pair of folding rollers 16, between which - depending on the operating mode of the folding apparatus - individual copies or copies lying one above the other are pushed in by the folding blades 11. The products folded in this way are laid out on a delivery belt 18 by means of a paddle wheel 17.

In Fig. 2 ist die Funktionsweise des Schneid-/Sammelzylinders 4 im Betriebsmodus "Nicht-Sammeln" dargestellt.2 shows the functioning of the cutting / collecting cylinder 4 in the “non-collecting” operating mode.

Der in den Zylinderspalt 19 einlaufende Bahnbereich 20 wird von aus dem Falzzylinder 5 ausgefahrenen Punkturen ergriffen und am Umfang des Falzzylinders 5 gehalten. Nach einer halben Zylinderumdrehung des Falzzylinders 5 fahren die Punkturen wieder in den Falzzylinder 5 ein und der Bahnbereich 20 wird durch einen Schnitt zwischen Schneidmesser 6 und Messerbalken 12 zu einem abgetrennten Exemplar 20'. Durch ein Falzmesser 11, welches an einer Falzmesserwelle 10 aufgenommen ist, wird das abgetrennte Exemplar 20' zwischen zwei Falzwalzen 16 eingestoßen und die ausgefahrenen Punkturen 13 ergreifen von neuem einen herangeführten Bahnbereich 20. So erhält das Exemplar 20' einen quer zum im Trichter 2 erzeugten Längsfalz verlaufenden weiteren Falz. Dann gelangen die Exemplare 20' in die Taschen des Schaufelrades 17, von dem sie auf das Auslageband 18 ausgelegt werden. Im hier skizzierten Produktionsmodus "Nicht-Sammeln" sind die Punkturen 7 außer Funktion, sie verbleiben in der Mantelfläche des Schneid-/Sammelzylinders 4 eingefahren.The web area 20 entering the cylinder gap 19 is gripped by punctures extended from the folding cylinder 5 and held on the circumference of the folding cylinder 5. After half a cylinder revolution of the folding cylinder 5, the punctures move back into the folding cylinder 5 and the web area 20 becomes a severed specimen 20 'by a cut between the cutting knife 6 and the cutter bar 12. By means of a folding knife 11, which is received on a folding knife shaft 10, the severed specimen 20 'is pushed in between two folding rollers 16 and the extended punctures 13 again grip an approached web area 20. Thus, the specimen 20' receives one that is generated in the hopper 2 Longitudinal fold further fold. Then the specimens 20 'get into the pockets of the paddle wheel 17, from which they are laid out on the delivery belt 18. In the "non-collecting" production mode outlined here, the punctures 7 are inoperative, they remain retracted in the lateral surface of the cutting / collecting cylinder 4.

Die Funktionsweise im Betriebsmodus "Sammeln" ist in den Fig. 3a, 3b, 3c dargestellt.The mode of operation in the "collecting" operating mode is shown in FIGS. 3a, 3b, 3c.

In der Darstellung gemäß Fig. 3a wird ein in den Zylinderspalt 19 einlaufender - hier gestrichelt dargestellter - Bahnbereich 22 von ausgefahrenen Punkturen 7 am Schneid-/Sammelzylinder 4 ergriffen. Die Punkturen 13a und 13b des doppeltgroßen Falzzylinders 5 verbleiben in ihrer eingefahrenen Position.In the illustration according to FIG. 3 a, a web area 22 entering the cylinder gap 19 — shown here in broken lines — is gripped by extended punctures 7 on the cutting / collecting cylinder 4. The punctures 13a and 13b of the double-sized folding cylinder 5 remain in their retracted position.

Im in Fig. 3b gezeigten Zustand hat sich der Falzzylinder 5 um eine halbe Umdrehung gedreht, während der Schneid-/Sammelzylinder 4 eine ganze Umdrehung ausgeführt hat. Dabei ist der gestrichelt gezeichnete Bahnbereich 22 komplett auf dem Umfang des Schneid-/Sammelzylinders 4 aufgenommen und wird nach dem Schnitt als Exemplar 22' bezeichnet. Zu diesem Zeitpunkt, unmittelbar nach dem Schnitt des Schneidmessers 6, fahren die Punkturen 7, die über Punkturenhebel 8 an einer Lagerungswelle 9 aufgenommen sind, in den Umfang des Schneid-/Sammelzylinders 4 zurück und geben somit das Exemplar 22' frei. Dieses wird unmittelbar danach zusammen mit dem neu ankommenden Bahnbereich 23 von ausgefahrenen Punkturen 13b ergriffen. Durch diesen "Punkturenwechsel" werden der Bahnbereich 23 und das Exemplar 22' übereinanderliegend am Umfang des Falzzylinders 5 fixiert, bis dieser eine halbe Umdrehung ausgeführt hat. In diesem Augenblick wird der Bahnbereich 23 durch einen Schnitt des Schneidmessers 6 mit dem Messerbalken 12 abgetrennt. Die die Exemplare 22' und 23' fixierenden Punkturen 13b fahren zurück in den Falzzylinder 5, bevor, wie Fig. 3c zu entnehmen ist, eines der Falzmesser 11 die übereinanderliegenden Exemplare 22' und 23' in den Spalt zwischen den Falzwalzen 11 einstößt. Mit 24 ist ein anschließend in den Zylinderspalt 19 einlaufender Bahnbereich bezeichnet, der im Betriebsmodus "Sammeln" von ausgefahrenen Punkturenstiften 7 des Schneid-/Sammelzylinders 4 ergriffen wird.In the state shown in FIG. 3b, the folding cylinder 5 has rotated by half a turn, while the cutting / collecting cylinder 4 has made one complete turn. The path area 22 shown in dashed lines is completely recorded on the circumference of the cutting / collecting cylinder 4 and is cut as a copy 22 'after the cut. designated. At this time, immediately after the cutting knife 6 has been cut, the punctures 7, which are received on a bearing shaft 9 via puncture levers 8, move back into the circumference of the cutting / collecting cylinder 4 and thus release the specimen 22 '. This is taken up immediately afterwards together with the newly arriving web area 23 by extended punctures 13b. As a result of this “change of punctures”, the web area 23 and the specimen 22 ′ are fixed one above the other on the circumference of the folding cylinder 5 until the latter has made half a revolution. At this moment the web area 23 is cut off by cutting the cutting knife 6 with the cutter bar 12. The punctures 13b fixing the copies 22 'and 23' move back into the folding cylinder 5 before, as can be seen from FIG. 3c, one of the folding knives 11 pushes the copies 22 'and 23' lying one above the other into the gap between the folding rollers 11. 24 is a web area which then enters the cylinder gap 19 and is gripped by extended puncture pins 7 of the cutting / collecting cylinder 4 in the “collecting” operating mode.

In den Fig. 4a, b ist ein Längsschnitt durch einen Schneid-/Sammelzylinder samt eines Details der Lagerungswelle dargestellt.4a, b show a longitudinal section through a cutting / collecting cylinder together with a detail of the bearing shaft.

Der Antrieb des Schneid-/Sammelzylinders 4 erfolgt durch ein Antriebsritzel 26 und wird über eine Antriebswelle mit Wellenfortsatz 35 übertragen. In einer Seitenwand 25 des Falzapparates ist eine Seitenwandbuchse 33 eingelassen, welche über Wälzlager das erste Kraftübertragungselement 29 abstützt. Dieses ist gleichzeitig von einem Wälzlager auf der Welle 35 des Schneid /Sammelzylinders 4 unterstützt. Am zylinderseitigen Ende des ersten Kraftübertragungselementes 29 ist ein Kurvenkörper 27 befestigt, der in einer Kurvenbahn 28 die Laufrollen 41 aufnimmt, mit welchen die Lagerungswellen 9 und damit die Punkturen 7, 21 aktivierbar sind.The cutting / collecting cylinder 4 is driven by a drive pinion 26 and is transmitted via a drive shaft with a shaft extension 35. A side wall bushing 33 is embedded in a side wall 25 of the folding apparatus and supports the first force transmission element 29 via roller bearings. This is supported at the same time by a roller bearing on the shaft 35 of the cutting / collecting cylinder 4. At the cylinder-side end of the first force transmission element 29, a cam body 27 is attached, which in a cam track 28, the rollers 41st records with which the bearing shafts 9 and thus the punctures 7, 21 can be activated.

An der Seitenwand 25 ist eine gehäusefeste Markierung 32 aufgenommen, welche mit der Zylindermarkierung 36 in Übereinstimmung bringbar ist. Fluchten beide Markierungen miteinander, sind die Punkturen 7 in die Mantelfläche des Schneid /Sammelzylinders 4 eingefahren.A marking 32 fixed to the housing is accommodated on the side wall 25 and can be brought into line with the cylinder marking 36. If both markings are in alignment with one another, the punctures 7 are moved into the lateral surface of the cutting / collecting cylinder 4.

Am ersten Kraftübertragungselement 29 sind zwei Krafteinleitungsstellen 29a, 29b vorgesehen, die als Innen- bzw. Außenverzahnung ausgeführt sind. Auf dem Wellenfortsatz 35 befindet sich eine Schiebeverzahnung 34, welche das zweite Kraftübertragungselement darstellt. Die Schiebeverzahnung 34 ist durch eine Verriegelung 30, die auf zwei Ringnuten 37, 38 einer Stellwelle 39 einwirkt, arretierbar; durch ein am Ende des Wellenfortsatzes 35 an der Stellwelle 39 aufgenommenes Handrad 31 ist die Schiebeverzahnung 34 koaxial zum ersten Kraftübertragungselement 29 betätigbar. Parallel zum Wellenfortsatz 35 ist in der Seitenwandbuchse 33 eine Stummelwelle aufgenommen, auf welcher eine mit zwei Verzahnungen 42, 43 vesehene Hülse aufgenommen ist. Die Schiebeverzahnung 34 ist sowohl mit der Verzahnung 43 als auch mit der Innenverzahnung 29b des ersten Kraftübertragungselementes 29 in Eingriff zu bringen, während die Verzahnung 42 andauernd mit der Außenverzahnung 29a des ersten Kraftübertragungselementes 29 kämmt.On the first force transmission element 29, two force introduction points 29a, 29b are provided, which are designed as internal or external teeth. There is a sliding toothing 34 on the shaft extension 35, which represents the second force transmission element. The sliding toothing 34 can be locked by a lock 30, which acts on two annular grooves 37, 38 of an actuating shaft 39; The sliding toothing 34 can be actuated coaxially to the first force transmission element 29 by means of a handwheel 31 received on the actuating shaft 39 at the end of the shaft extension 35. Parallel to the shaft extension 35, a stub shaft is received in the side wall bushing 33, on which a sleeve provided with two toothings 42, 43 is received. The sliding toothing 34 is to be brought into engagement with the toothing 43 as well as with the inner toothing 29b of the first force transmission element 29, while the toothing 42 continuously meshes with the outer toothing 29a of the first force transmission element 29.

Im in Fig. 4a gezeigten Zustand kämmt die Schiebeverzahnung 34 mit der Verzahnung 43. Dadurch leitet der Schneid-/Sammelzylinder 4 den Antrieb in die Verzahnung 43 ein. Von dieser fließt der Antrieb über die Verzahnung 42 mit kleinerem Durchmesser an die Außenverzahnung 29a des ersten Kraftübertragungselementes 29 und damit in den Kurvenkörper 27. Durch die Untersetzung der Verzahnung 42, 29a rotiert der Kurvenkörper 27 nur halb so schnell wie der Schneid-/Sammelzylinder 4, wodurch dessen Punkturen 7 nur bei jeder zweiten Umdrehung aus der Mantelfläche ausfahren und somit bei jeder zweiten Umdrehung ein Exemplar auf seinem Umfang gesammelt werden kann.In the state shown in FIG. 4a, the sliding toothing 34 meshes with the toothing 43. As a result, the cutting / collecting cylinder 4 introduces the drive into the toothing 43. From this, the drive flows via the toothing 42 with a smaller diameter to the external toothing 29a of the first force transmission element 29 and thus into the cam body 27. By reducing the Toothing 42, 29a, the cam body 27 rotates only half as fast as the cutting / collecting cylinder 4, so that its punctures 7 only extend from the outer surface every second revolution and thus a specimen can be collected on its circumference with every second revolution.

Die Fig. 5a, b geben einen Längsschnitt durch den Schneid-/Sammelzylinder 4 im Modus "Nicht-Sammeln" wieder. Der Unterschied zu Fig. 4a liegt in der anderen Arbeitsposition der Schiebeverzahnung 34. Vor der vorzunehmenden Umstellung auf diese Betriebsart, werden nach Fluchten der Markierungen 32 und 36 die Punkturen 7 in die Mantelfläche des Schneid-/Sammelzylinders 4 eingefahren. Dann wird die Verriegelung 30 betätigt, per Handrad 31 die Schiebeverzahnung 34 koaxial zum ersten Kraftübertragungselement 29 verschoben. In dieser Stellung ist die Schiebeverzahnung 34 durch die Verriegelung 30 und die Ringnut 38 arretiert. Nunmehr kämmt die Schiebeverzahnung 34 mit der Innenverzahnung 29b gleichen Teilkreisdurchmessers, wodurch sich ein Übersetzungsverhältnis von 1 gibt. Die Verzahnungen 42, 43 laufen leer mit, Kurvenkörper 27 und Schneid-/Sammelzylinder 4 rotieren mit derselben Umfangsgeschwindigkeit, die Punkturen 7 werden mithin nicht betätigt, wodurch keine Exemplare auf dem Umfang des Schneid-/Sammelzylinders 4 gesammelt werden, im Gegensatz zum Zustand in Fig. 4a.5a, b show a longitudinal section through the cutting / collecting cylinder 4 in the "non-collecting" mode. The difference to FIG. 4a lies in the other working position of the sliding toothing 34. Before the changeover to this operating mode is to be carried out, the punctures 7 are moved into the lateral surface of the cutting / collecting cylinder 4 after the marks 32 and 36 have been aligned. Then the lock 30 is actuated, the sliding toothing 34 is shifted coaxially to the first force transmission element 29 by means of the handwheel 31. In this position, the sliding toothing 34 is locked by the lock 30 and the annular groove 38. Now the sliding toothing 34 meshes with the internal toothing 29b of the same pitch circle diameter, which results in a transmission ratio of 1. The teeth 42, 43 run idle, cam body 27 and cutting / collecting cylinder 4 rotate at the same circumferential speed, the punctures 7 are therefore not actuated, so that no copies are collected on the circumference of the cutting / collecting cylinder 4, in contrast to the state in Fig. 4a.

Es leuchtet ein, daß nach dem geschilderten Prinzip auch andere Umfangsgeschwindigkeitsverhältnisse zwischen Schneid-/Sammelzylinder 4 und Kurvenkörper 27 realisiert werden können; dies hängt vom zur Verfügung stehenden Bauraum sowie von der Anzahl der Punkturenreihen auf dem Umfang und den Durchmesserverhältnissen zwischen Falzzylinder 5 und Schneid-/Sammelzylinder 4 ab.It is obvious that other circumferential speed ratios between cutting / collecting cylinder 4 and cam body 27 can also be realized according to the principle described; this depends on the available space as well as on the number of rows of punctures on the circumference and the diameter ratio between folding cylinder 5 and cutting / collecting cylinder 4.
