Description

Die vorgeschlagene Einrichtung bezieht sich auf das Zickzackfalzen von aus Papier, Gewebe, Folie, Kunststoff o.dgl. bestehenden Bahnen mit einer hin- und herschwenkenden, aus mindestens zwei Teilen bestehenden, mittels Gelenk miteinander verbundenen, relativ zueinander beweglichen, aus Platten, Blechen o.dgl. zusammengesetzten kanalartigen Führungsvorrichtung für die zu falzende Bahn oder die zu falzenden Bahnen, wobei der in Laufrichtung der Bahnen folgende Teil der Führungsvorrichtung eine aus umlaufenden Walzen bestehende Zugvorrichtung für die jeweils zu falzende Bahn oder die jeweils zu falzenden Bahnen enthält.The proposed device relates to the zigzag folding of paper, fabric, film, plastic or the like. existing webs with a back and forth swiveling, consisting of at least two parts, interconnected by means of a joint, movable relative to each other, made of plates, sheets or the like. Compound channel-like guiding device for the web or webs to be folded, the part of the guiding device following in the running direction of the webs containing a pulling device consisting of rotating rollers for the web or webs to be folded in each case.

Einrichtungen der vorgenannten Art werden an Druckmaschinen, insbesondere Formulardruckmaschinen verwendet. Die in diesen Maschinen bedruckte, gestanzte oder.anderweitig bearbeitete Bahn wird einer Zickzackfalzeinrichtung und dieser nachfolgend einem zickzackförmig gefalzten Stapel zugeführt oder zu einem solchen Stapel abgelegt. In Einrichtungen der genannten Art kann nicht nur eine Bahn zugeführt werden. Es ist auch möglich, daß mehrere übereinander liegende Bahnen die genannten Maschinen durchlaufen, Dies ist beispielsweise dann der Fall, wenn ein aus mehreren Seiten bestehendes Formular hergestellt werden soll. Um die vorliegende Erfindung möglichst anschaulich zu beschreiben, wird aus Gründen der Vereinfachung im folgenden nur noch von einer Bahn auch dann gesprochen, v'enn es sich um eine aus mehreren aufeinander liegenden einzelnen Bahnen bestehende mehrlagige Bahn handelt.Devices of the aforementioned type are used on printing machines, in particular form printing machines. The web printed, punched or otherwise processed in these machines is fed to a zigzag folding device and subsequently fed to a zigzag-folded stack or deposited into such a stack. In facilities of the type mentioned, not only a web can be fed. It is also possible for a plurality of webs lying one above the other to run through the machines mentioned. This is the case, for example, when a form consisting of several pages is to be produced. In order to describe the present invention as clearly as possible, the simplification in the following only by a sheet will also be spoken of reasons, v 'there is a hen consists of several superposed individual panels are layered web.

Zickzackfalzapparate enthalten in vielen Fällen einen aus mehreren Teilen bestehenden Führungskanal für die Bahn, welche dazu dient, die Bahn hin und her zu führen, damit sie an den in die Bahn eingearbeiteten, quer zur Laufrichtung der Bahn verlaufenden Perforationen abknicken kann, ohne daß die Bahn beispielsweise durch Luftturbulenzen aufgebauscht wird. Mehrteilige Führungsvorrichtungen für die Bahn erbringen dabei eine weit bessere Führung der abzulegenden Bahn als einteilige Führungsvorrichtungen.In many cases, zigzag folders contain a multi-part guide channel for the web, which serves to guide the web back and forth so that it can snap off the perforations incorporated into the web and running transversely to the running direction of the web without the web for example, is inflated by air turbulence. Multi-part guide devices for the web provide far better guidance of the web to be deposited than single-piece guide devices.

Da die Führungsvorrichtungen hin- und hergeschwenkt werden, und da die zu falzende Bahn nicht nur den Falzapparat sondern auch die dem Falzapparat vorgeschaltete Maschine, beispielsweise die Druckmaschine, möglichst schnell durchlaufen soll, entstehen Trägheitskräfte an den hin- und herschwenkenden Teilen des Führungskanals. Diese Trägheitskräfte nehmen bei hohen Laufgeschwindigkeiten eine Größenordnung an, die die Laufgeschwindigkeit der Druckmaschine und damit diejenige der Bahn begrenzen. Diese Begrenzung kann beispielsweise derart sein, daß die dem Falzapparat vorgeschaltete-Maschine wegen des nachgeschalteten Falzapparates unterhalb ihrer maximalen Geschwindigkeit laufen muß.Since the guiding devices are pivoted back and forth, and since the web to be folded should not only pass through the folder but also the machine upstream of the folder, for example the printing press, as quickly as possible, inertial forces arise on the parts of the guide channel which pivot back and forth. At high running speeds, these inertial forces take on an order of magnitude that limit the running speed of the printing press and thus that of the web. This limitation can be such, for example, that the machine upstream of the folder must run below its maximum speed because of the downstream folder.

Einrichtungen der vorgenannten Art sind beispielsweise aus der DE-PS 10 70 010 bekannt. Diese Einrichtung enthält jedoch Zugwalzen, welche in Laufrichtung der Bahn gesehen am unteren Ende der Schwenkeinrichtung oder Führungseinrichtung für die Bahn angeordnet sind. Diese Anordnung der Zugwalzen hat Massenkräfte zur Folge, welche die maximale Geschwindigkeit der Falzeinrichtung in unerwünschter Weise begrenzen, Eine andere Einrichtung ist beispielsweise aus der DE-PS 11 52 301 vorbekannt. Diese Einrichtung enthält in Richtung der zu falzenden Bahn gesehen an ihrem unteren Teil nicht allein Zugwalzen, sondern sogar einen doppelten Satz dieser Walzen, zwischen denen Bänder gespannt sind, Auch diese Einrichtung führt zu Trägheitskräften, welche ein Ausmaß annehmen, daß die der Falzeinrichtung vorgeschaltete Maschine in ihrer Leistung in unerwünschter Weise begrenzt werden muß.Devices of the aforementioned type are known for example from DE-PS 10 70 010. However, this device contains traction rollers, which are arranged at the lower end of the pivoting device or guide device for the web, as viewed in the direction of travel of the web. This arrangement of the pull rollers results in mass forces which undesirably limit the maximum speed of the folding device, Another device is known for example from DE-PS 11 52 301. This device contains, in the direction of the web to be folded, not only pull rollers at its lower part, but even a double set of these rollers, between which belts are stretched. This device also leads to inertial forces which assume a level that the machine upstream of the folding device their performance must be limited in an undesirable manner.

Es besteht somit die Aufgabe, eine Einrichtung der genannten Art zu schaffen, bei der die durch die Hin- und Herbewegung der Führungsvorrichtung hervorgerufenen Trägheits- oder Massenkräfte wesentlich geringer sind als bei vorbekannten Einrichtungen.It is therefore the task of creating a device of the type mentioned, in which the inertial or inertial forces caused by the back and forth movement of the guide device are substantially lower than in previously known devices.

Diese Aufgabe wird dadurch gelöst, daß die aus Walzen bestehende Zugvorrichtung in der Nähe des Drehgelenkes zweier Teile der Führungsvorrichtung angeordnet ist, die Seitenwände der Führungsvorrichtung im Bereich des Drehgelenkes mindestens eine Öffnung zwischen den Teilen der Führungsvorrichtung enthalten und mindestens die die Oberflächen einer jeweils zu falzenden Bahn kontaktierenden Teile der Seitenwände der Führungseinrichtung mit Profil versehen sind.This object is achieved in that the pulling device consisting of rollers is arranged in the vicinity of the swivel joint of two parts of the guide device, the side walls of the guide device in the region of the swivel joint contain at least one opening between the parts of the guide device and at least the surfaces of one to be folded Parts of the side walls of the guide device that contact the web are provided with a profile.

Aufgrund der vorgeschlagenen Lösung ist es nicht allein möglich, die Arbeitsgeschwindigkeit der Falzeinrichtung, sondern auch die Arbeitsgeschwindigkeit der der Falzeinrichtung vorgeschalteten Maschine, beispielsweise einer Formulardruckmaschine, zu erhöhen, Auf diese Weise wird die Leistung der gesamten Maschine beträchtlich vergrößert.Due to the proposed solution, it is not only possible to increase the operating speed of the folding device, but also the working speed of the machine upstream of the folding device, for example a form printing machine. In this way, the performance of the entire machine is considerably increased.

Anhand eines in den beigefügten Figuren schematisch abgebildeten, den Erfindungsgedanken nicht begrenzenden Ausführungsbeispiels wirddie vorgeschlagene Einrichtung näher erläutert.The proposed device is explained in more detail with reference to an exemplary embodiment schematically depicted in the attached figures, which does not limit the inventive concept.

Das Ausführungsbeispiel kann in verschiedener Weise abgeändert werden, ohne daß der durch die Grundidee der Erfindung abgesteckte Rahmen verlassen würde,The exemplary embodiment can be modified in various ways without departing from the framework defined by the basic idea of the invention,

In den Figuren sind im vorliegenden Zusammenhang nicht wesentliche Teile der Einrichtung wegen einer übersichtlicheren Darstellungsweise nicht gezeichnet, da sie dem Fachmann hinreichend bekannt sind. In den Figuren sind nur diejenigen Teile gezeigt, die zur näheren Erläuterung der Erfindung und ihrer Vorteile erforderlich sind.In the present context, non-essential parts of the device are not shown in the figures because of a clearer representation, since they are sufficiently known to the person skilled in the art. In the figures, only those parts are shown which are necessary for a more detailed explanation of the invention and its advantages.

Die bereits quer zu ihrer Laufrichtung in bestimmten Abständen mit einer Perforation versehene, aus einer oder mehreren Lagen bestehende Bahn 1 aus Papier, Folie, Gewebe o.dgl. läuft von oben her in den Falzapparat ein. Die Bahn wird beispielsweise an der Stelle 2 mit Hilfe eines Schlägers 3 im Bereich der Querperforation abgeknickt und bildet dadurch einen zickzackförmigen Stapel 4. Zu diesem Zweck durchläuft die Bahn 1 mehrere in Laufrichtung der Bahn hintereinander angeordnete kanalartige Führungsvorrichtungen, welche die verschiedenen Teile eines Papierführungskanals bilden. Die Bewegung dieser Teile wird durch Pleuelstangen 5 und 6 ermöglicht, welche von angetriebenen Exzentern 7 und 8 ihrerseits bewegt werden. Die beiden Teile 9 und 10 der Führungsvorrichtung sind durch ein Gelenk 11 miteinander verbunden und demzufolge relativ zueinander verschwenkbar, Der in Laufrichtung der Bahn 1 erste Teil 9 der Führungsvorrichtung ist außerdem um ein weiteres Gelenk 12 verschwenkbar, welches sich in dem Gestell der Falzeinrichtung befindet. Das zweite Gelenk 12 ist somit ortsfest, während das erste Gelenk 11 durch die Bewegung der Pleuelstange 5 hin und her verschwenkt wird. Die kanalartige Führungsvorrichtung ist demzufolge insgesamt aus mehreren in Laufrichtung der Bahn 1 folgenden hintereinander angeordneten Teilen zusammengesetzt.The web 1, which is provided with a perforation and is made up of one or more layers of paper, film, fabric or the like at right intervals, is provided with a perforation at certain intervals. runs into the folder from above. The web is abge for example at point 2 with the help of a racket 3 in the area of the transverse perforation kinks and thereby forms a zigzag-shaped stack 4. For this purpose, the web 1 passes through a plurality of channel-like guiding devices arranged one behind the other in the running direction of the web, which form the different parts of a paper guiding channel. The movement of these parts is made possible by connecting rods 5 and 6, which in turn are moved by driven eccentrics 7 and 8. The two parts 9 and 10 of the guide device are connected to one another by a joint 11 and consequently pivotable relative to one another. The first part 9 of the guide device in the running direction of the web 1 can also be pivoted about a further joint 12 which is located in the frame of the folding device. The second joint 12 is thus stationary, while the first joint 11 is pivoted back and forth by the movement of the connecting rod 5. The channel-like guide device is consequently composed of a total of several parts arranged one behind the other in the running direction of the web 1.

Das zweite Gelenk 12 enthält eine angetriebene Welle 13, welche in dem Gestell 14 der Maschine drehbar gelagert ist. Mit der Welle 13 ist eine Riemenscheibe 15 verbunden, über welche ein nicht dargestellter Riemen läuft, der die zweite Riemenscheibe 16 antreibt. Die zweite Riemenscheibe 16 ist mit einer Welle 17 verbunden, deren geometrische Mitte dem Drehpunkt des Gelenkes 11 entspricht. Mit der Welle 17 ist ferner ein Zahnrad 18 verbunden, welches in weitere Zahnräder 19 und 20 eingreift. Die Zahnräder 19 und 20 sind ihrerseits mit Zugwalzen 21 und 22 verbunden. Die Zugwalzen 21 und 22 sind in dem in Laufrichtung der Bahn 1 zweiten Teil 10 der Führungsvorrichtung drehbar gelagert. Zwischen der Drehachse des Gelenkes 11 und den Achsen der Zugwalzen 21 und 22 verbleibt somit ein Abstand 23, welcher möglichst gering sein soll. Damit kommt die aus den Walzen 21 und 22 bestehende Zugvorrichtung für die Bahn 1 in unmittelbare Nähe des die beiden Teile 9 und 10 der Führungsvorrichtung verbindenden Drehgelenkes 11 zu liegen. Dieser Abstand 23 kann beispielsweise dadurch gering gehalten werden, daß möglichst hochfeste Werkstoffe für die Zahnräder 18,19 und 20 verwendet werden.The second joint 12 contains a driven shaft 13 which is rotatably mounted in the frame 14 of the machine. A pulley 15 is connected to the shaft 13, via which a belt (not shown) runs, which drives the second pulley 16. The second pulley 16 is connected to a shaft 17, the geometric center of which corresponds to the pivot point of the joint 11. A gear 18 is also connected to the shaft 17, which meshes with further gears 19 and 20. The gears 19 and 20 are in turn connected to pull rollers 21 and 22. The pull rollers 21 and 22 are rotatably mounted in the second part 10 of the guide device in the running direction of the web 1. Between the axis of rotation of the joint 11 and the axes of the pull rollers 21 and 22 A distance 23 thus remains, which should be as small as possible. Thus the pulling device for the web 1 consisting of the rollers 21 and 22 comes to lie in the immediate vicinity of the swivel joint 11 connecting the two parts 9 and 10 of the guiding device. This distance 23 can be kept small, for example, by using the highest possible strength materials for the gears 18, 19 and 20.

Die kanalartige Führungsvorrichtung für die Bahn 1 enthält Seitenwände 24,25,26 und 27, welche mindestens so breit sind, wie die zu falzende Bahn 1. Diese Seitenwände sind mit entsprechenden Halterungen 28 und 29, welche sich an dem ersten und an dem zweiten Teil der Führungsvorrichtung befinden, verbunden. Diese Seitenwände bestehen im allgemeinen aus Blechen, welche zu einem von der Führungsbahn 1 zu durchlaufenden Führungskanal verschweißt oder verschraubt werden. Nach der vorliegenden Erfindung werden auch hierfür Bleche aus Aluminium oder hochwertigem Stahl bevorzugt, damit diese Bleche mög- lichst leicht aber schwingungsfest ausgeführt werden können. Beispielsweise kann hierzu sogenannter Edelstahl verwendet werden. Diese Seitenwände werden beim Hin- und Hergehen des Kanals von der zu falzenden Bahn 1 kontaktiert und geraten somit zumindest zeitweise mit der Bahn in Berührung. Um die Stabilität dieser Seitenwände noch zu erhöhen, d.h. um die Seitenwände möglichst dünn und leicht ausführen zu können, sind sie mit einem Profil versehen, welches beispielsweise aus den Riffelungen 30 und 31 bestehen kann; Es ist aber auch eine andere Art der Profilierung, als in den Figuren dargestellt, möglich.The channel-like guiding device for the web 1 contains side walls 24, 25, 26 and 27 which are at least as wide as the web 1 to be folded. These side walls have corresponding holders 28 and 29, which are located on the first and on the second part the guide device are connected. These side walls generally consist of metal sheets which are welded or screwed to a guide channel to be passed through by the guideway 1. According to the present invention, this metal of aluminum or high-grade steel are preferred, so that these sheets possible l i ch st can be performed easily but vibration resistant. For example, so-called stainless steel can be used for this. These side walls are contacted by the web 1 to be folded when the channel travels and thus come into contact with the web at least temporarily. In order to further increase the stability of these side walls, ie in order to be able to make the side walls as thin and light as possible, they are provided with a profile, which can consist, for example, of corrugations 30 and 31; However, a different type of profiling than that shown in the figures is also possible.

Im Bereich des zwischen dem ersten und dem zweiten Teil der Führungsvorrichtung gelegenen Gelenkes 11 sind die Seitenwände nach Art von Düsen abgewinkelt, so daß sich zwischen den Seitenwänden der einzelnen Teile der Führungsvorrichtung Düsen oder Fenster bilden, Beispielsweise ist die Seitenwand 24 entsprechend dem Winkel α und die Seitenwand 27 entsprechend dem Winkel β abgewinkelt, Durch das dadurch beispielsweise über die gesamte Breite der zu falzenden Bahn reichende Fenster 32 kann Luft in die kanalartigen Teile der Führungsvorrichtung einströmen und sich zwischen die Seitenwände und die zu falzende Bahn 1 schieben. Diese Luft wandert mit der Bahn 1 mit, Daneben ist es denkbar, daß die genannten Fenster auch in anderer Weise als im Ausführungsbeispiel dargestellt, hergestellt werden können, beispielsweise unter Verzicht auf die Abwinkelungen der Seitenwände,In the area of the joint 11 located between the first and the second part of the guide device, the side walls are angled in the manner of nozzles, so that nozzles or windows are formed between the side walls of the individual parts of the guide device. For example, the side wall 24 corresponds to the angle α and the side wall 27 is angled according to the angle β. The window 32 that extends over the entire width of the web to be folded, for example, allows air to flow into the channel-like parts of the guide device and slide between the side walls and the web 1 to be folded. This air travels with the web 1. In addition, it is conceivable that the windows mentioned can also be produced in a different way than shown in the exemplary embodiment, for example without the angling of the side walls,

Mit Hilfe der vorgeschlagenen Einrichtung ist es möglich, sowohl relativ schwere und dicke als auch relativ leichte und dünne Bahnen 1 zu verarbeiten.With the help of the proposed device, it is possible to process both relatively heavy and thick as well as relatively light and thin webs 1.

Es versteht sich für den Fachmann von selbst, daß die Pleuelstangen 5 und 6, sowie die Halterungen für die Seitenwände 24.25,26 und 27 an beiden Längskanten der zu falzenden Bahn angeordnet sein können, Dies läuft im wesentlichen auf eine symmetrische Ergänzung der Figuren hinaus.It goes without saying for a person skilled in the art that the connecting rods 5 and 6, as well as the holders for the side walls 24.25, 26 and 27, can be arranged on both longitudinal edges of the web to be folded. This essentially amounts to a symmetrical addition to the figures.
