Description

Die Erfindung betrifft eine Vorrichtung zum Aufteilen eines Stromes aus Druckexemplaren, mittels zweier gegeneinander angestellten rotierenden Ablenkelementen, insbesondere Zylindern, durch die die Druckexemplare jeweils in einen von zwei nachgeordneten Transportpfaden abgedrängt werden.The invention relates to a device for dividing a stream of printed copies, by means of two rotating deflecting elements, in particular cylinders, by means of which the printed copies are each pushed into one of two downstream transport paths.

Aus der US-PS 43 73 713 ist eine Vorrichtung zum Aufteilen der bereits von einer Druckträgerbahn abgeschnittener Druckexemplare bekannt. Die Druckexemplare werden mittels eines kontinuierlich umlaufenden Transportmittels, beispielsweise Bändern, einem rotierenden Zylinderpaar zugeführt, hinter dem Ableitzungen angeordnet sind, wobei jeder Zylinder des Zylinderpaares mindestens ein Segment aufweist, das aus dem Zylindermantel heraus in die Transportbahn der Druckexemplare ragt und die umfangsmäßige Lage der Segmente und die Drehzahl des Zylinderpaares bezogen auf den Takt der ankommenden Druckexemplare so festgelegt sind, daß diese durch das Segment des einen Zylinders unter die feststehende Ableitzunge in einen ersten Transportpfad und durch das Segment des anderen Zylinders über die Ableitzunge in einen zweiten Transportpfad führbar sind. Der Nachteil dieser Vorrichtung besteht unter anderem darin, daß der Verteilervorrichtung ein Schneidwalzenpaar vorangestellt werden muß, um die üblicherweise von einer Druckträgerbahn abgeschnittenen Druckexemplare bereitzustellen. Dadurch ergibt sich eine voluminöse Bauweise und ein hoher Kostenaufwand.From US-PS 43 73 713 a device for dividing the print copies already cut from a print carrier web is known. The printed copies are fed to a rotating pair of cylinders by means of a continuously rotating means of transport, for example belts, behind which derivations are arranged, each cylinder of the pair of cylinders having at least one segment which protrudes from the cylinder jacket into the transport path of the printed copies and the circumferential position of the segments and the number of revolutions of the pair of cylinders in relation to the cycle of the incoming printed copies are determined such that they can be guided into a first transport path through the segment of one cylinder under the fixed derivation line and into a second transport path through the segment of the other cylinder via the derivation line. The disadvantage of this device is, inter alia, that the distributor device must be preceded by a pair of cutting rollers in order to provide the print copies which are usually cut off from a print carrier web. This results in a voluminous construction and a high cost.

Aufgabe der Erfindung ist es, eine Vorrichtung zum Aufteilen des Stromes aus Druckexemplaren zu schaffen, der es möglich ist, die Druckexemplare auch gleichzeitig von einer Druckträgerbahn zu trennen und die neben der Trennfunktion auch die Verteilerfunktion ausführt. Diese Aufgabe wird durch die Anwendung der Merkmale des kennzeichnenden Teils des Anspruchs 1 gelöst. Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen und aus der Beschreibung in Verbindung mit den Zeichnungen. In diesen zeigen:

  • Fig. 1 eine schematische Darstellung der erfindungsgemäßen Verteiler- und Schneidvorrichtung und
  • Fig. 2 die Vorrichtung gemäß Fig. 1 mit einer zweiten Arbeitsposition der Schneid- und Ablenkzylinder.
The object of the invention is to provide a device for dividing the flow of printed copies, which is also possible to separate the printed copies from a print carrier web at the same time and which, in addition to the separating function, also carries out the distributor function. This object is achieved by applying the features of the characterizing part of claim 1. Further training of the Invention emerge from the subclaims and from the description in conjunction with the drawings. In these show:
  • Fig. 1 is a schematic representation of the distributor and cutting device according to the invention and
  • Fig. 2 shows the device of FIG. 1 with a second working position of the cutting and deflecting cylinders.

Wie aus den Darstellungen ersichtlich, wird der erfindungsgemäßen Vorrichtung, die ein Schneidwerk 1 mit Weichen-Funktionen umfaßt, eine Druckträgerbahn 2 vorzugsweise etwa vertikal zugeführt, und zwar über ein Zugwerk das die Rollenpaare 3, 4, und 5, 6 umfaßt.As can be seen from the illustrations, the device according to the invention, which comprises a cutting mechanism 1 with switch functions, is preferably supplied with a pressure carrier web 2 approximately vertically, specifically via a traction mechanism which comprises the pairs of rollers 3, 4 and 5, 6.

Im wesentlichen steht das erfindungsgemäße Schneidwerk 1 mit der Verteiler- bzw. Weichen-Funktion aus einem Schneidzylinderpaar, das die Schneidwalzen 7, 8 aufweist. Jede der Schneidwalzen 7, 8 ist mindestens mit einem aus der Mantelkontur überstehenden herausfahrbaren Messer 10, 11 und Schneidbalken 12, 13 ausgestattet. In jedem der Zylinder 7, 8 liegen jeweils die Messer 10, 11 diametrisch den Schneidbalken 12, 13 gegenüber.Essentially, the cutting unit 1 according to the invention with the distributor or switch function consists of a pair of cutting cylinders that have the cutting rollers 7, 8. Each of the cutting rollers 7, 8 is equipped with at least one knife 10, 11 and cutting bar 12, 13 which can be pulled out from the jacket contour. In each of the cylinders 7, 8, the knives 10, 11 are diametrically opposed to the cutting bars 12, 13.

Erfindungsgemäß sind die Schneidzylinder 7, 8 exzentrisch gelagert, so daß die zwischen diesen durchgeführte Druckträgerbahn 2 beim kontinuierlichen Drehen der Zylinder 7, 8 abwechselnd nach links (Fig. 1) und nach rechts (Fig.2) abgelenkt wird. Dabei ist gemäß der Erfindung dieser Ablenkvorgang durch die entsprechende zylindrische Lagerung so festglegt, daß von der Druckträgerbahn 2 die Druckexemplare 14 zwischen den Zylindern 7, 8 zugeschnitten werden, wenn der vorauslaufende Teil eines jeden. Druckexemplares bereits in einen Transportpfad eingeführt ist und die Position der Zylinder 7, 8 die Druckträgerbahn 2 über den anderen Transportpfad ablenkt.According to the invention, the cutting cylinders 7, 8 are mounted eccentrically, so that the print carrier web 2 carried out between them is alternately deflected to the left (FIG. 1) and to the right (FIG. 2) when the cylinders 7, 8 are continuously rotated. In this case, according to the invention, this deflection process is determined by the corresponding cylindrical bearing so that the print copies 14 between the cylinders 7, 8 are cut from the print carrier web 2 when the leading part of each. Print copies have already been inserted into a transport path and the position of the cylinders 7, 8 deflects the print carrier web 2 over the other transport path.

Vorzugsweise ist den den beiden Zylindern 7, 8 nachgeordneten Transportpfaden eine oder mehre Ableitzungen 15 vorangestellt, die die sichere Einführung der Druckträger 14 in eine der beiden Transportpfade begünstigen.The transport paths downstream of the two cylinders 7, 8 are preferably preceded by one or more derivations 15, which favor the secure insertion of the print carrier 14 into one of the two transport paths.

Der linke Transportpfad umfaßt umlaufende Bänder 16, 17, die um entsprechende Umlenk- und Transportrollen 18, 19, 20 geführt sind. Der rechte Transportpfad umfaßt die Bänder 21, 25, die in entsprechender Weise um Umlenk- bzw. Transportrollen 22, 23, 24 laufen.The left transport path comprises circulating belts 16, 17, which are guided around corresponding deflection and transport rollers 18, 19, 20. The right transport path comprises the belts 21, 25, which run in a corresponding manner around deflection or transport rollers 22, 23, 24.

Wie Fig. 1 zu entnehmen ist, befindet sich der vorauslaufende Teil eines Druckexemplares 14 bereits im rechten Transportpfad, bestehend aus den Bändern 21, 25, während die exzentrische Lagerung, die für den Zylinder 7 bei 26 und für den Zylinder 8 bei 27 angedeutet bewirkt, daß bei einer bestimmten Umfangsstellung der Zylinder 7, 8 diese die Druckträgerbahn 2 nach links, d.h. oberhalb des linken Transportpfades bestehend aus den Bändern 16, 17 abdrängen. Zu diesem in Fig. 1 in etwa dargestellten Zeitpunkt wird das Druckexemplar 14 zwischen den Zylindern 7, 8 bzw. zwischen dem Messer 11 und dem Schneidbalken 12 abgeschnitten. Durch weitere Drehung der Zylinder 7, 8 kann nunmehr das nachfolgend zuzuschneidende Druckexemplar nach unten geführt werden, so daß es in den linken Transportpfad bestehend aus den Bändern 16, 17 gelangt. Während dieses Vorganges erfolgt durch die inzwischen weiterdrehenden Zylinder 7, 8 eine Auslenkung der Druckträgerbahn 2 nach rechts, in die in Fig. 2 dargestellte Position, d.h. etwa oberhalb des rechten Transportpfades, bestehend aus den Bändern 21, 25. Zu diesem in Fig. 2 in etwa dargestellten Zeitpunkt erfolgt der Zuschnitt des nächsten Druckexemplares 14′, das mit seinem vorderen Ende bereits in den linken Transportpfad 16, 17 eingeführt ist. Nun wiederholt sich beim Weiterdrehen der Zylinder 7, 8 wieder die in Fig. 1 dargestellte Situation usw..As can be seen in FIG. 1, the leading part of a printed copy 14 is already in the right transport path, consisting of the belts 21, 25, while the eccentric bearing, which is indicated for the cylinder 7 at 26 and for the cylinder 8 at 27 that at a certain circumferential position of the cylinders 7, 8, the print carrier web 2 to the left, ie Push off above the left transport path consisting of belts 16, 17. At this point in time, which is roughly shown in FIG. 1, the printed copy 14 between the cylinders 7, 8 or between the knife 11 and the cutting bar 12 is cut off. By further rotation of the cylinders 7, 8, the print copy which is subsequently to be cut can now be guided downward, so that it reaches the left transport path consisting of the belts 16, 17. During this process, the cylinders 7, 8, which are now rotating further, deflect the print carrier web 2 to the right, into the position shown in FIG. approximately above the right transport path, consisting of the belts 21, 25. At this point in time, which is approximately shown in FIG. 2, the next printed copy 14 'is cut, the front end of which is already inserted into the left transport path 16, 17. Now, when the cylinders 7, 8 continue to rotate, the situation shown in FIG. 1 repeats itself again.

Durch die exzentrische Lagerung des Schneidzylinderpaares 7, 8 kann somit gleichzeitig mit dem Schneidvorgang zur Erzeugung der Druckexemplare 14 aus der Druckträgerbahn 2 eine Weichenfunktion ausgeübt werden, die rhythmisch die Druckträgerbahn 2 von dem einen Weicheneingang zum anderen auslenkt, so daß durch zeitgerechtes Abschneiden der Druckträger 14 bzw. 14′ eine Aufteilung der Druckträger 14 bzw. 14′ in den einen oder anderen der beiden Transportpfade 16, 17 bzw. 21, 25 erfolgt.Due to the eccentric mounting of the pair of cutting cylinders 7, 8, a switch function can thus be performed simultaneously with the cutting process for producing the print copies 14 from the print carrier web 2 are exercised, which rhythmically deflects the print carrier web 2 from one switch input to the other, so that by timely cutting off the print carrier 14 or 14 'a division of the print carrier 14 or 14' into one or the other of the two transport paths 16, 17 or 21, 25 takes place.
