Die Erfindung bezieht sich auf eine Messerführung für eine Vorrichtung zum Querschneiden von bandförmigem Material, z. B. aus Papier, mit ober- und unterhalb der Materialbahn in einer zu dieser senkrechten und in Laufrichtung liegenden Ebene parallel zueinander exzentrisch und gegensinnig umlaufenden Messern.The invention relates to a knife guide for a device for cross-cutting band-shaped material, e.g. B. made of paper, with above and below the material web in one to this perpendicular and in the running direction plane parallel to each other eccentrically and rotating in opposite directions Knives.
Es ist eine derartige Vorrichtung mit umlaufenden Messern zum. Abtrennen von Bahnstücken bekanntgeworden, bei welcher die Parallelführung der Messer zueinander durch ineinandergreifende Getrieberäder erreicht wird. Für jedes Messer dieser bekannten Konstruktion sind vier Getrieberäder erforderlich. Ferner kann infolge des zwischen den Zähnen der einzelnen Getrieberäder vorhandenen und auch notwendigen Spieles eine exakte Parallelführung der Schneidmesser nicht erreicht werden.It is such a device with rotating knives for. Separation of pieces of track has become known, in which the parallel guidance of the knives to each other by interlocking gear wheels is achieved. Four gear wheels are required for each knife of this known construction. Furthermore, as a result of the existing between the teeth of the individual gear wheels and also necessary clearance an exact parallel guidance of the cutting knife cannot be achieved.
Die der Erfindung zugrunde liegende Aufgabe besteht darin, eine im Aufbau einfache Konstruktion für die Parallelführung der Messer zueinander zu schaffen, die hohen Anforderungen hinsichtlich der genauen Führung der Messer gewachsen ist. Diese Aufgabe wird dadurch gelöst, daß an dem unteren Messer ein unterer Querbalken vorgesehen ist, wobei das obere Ende einer jeden Stange in je einem Kugellager geführt ist, die am oberen Querbalken des oberen Messers befestigt sind.The object on which the invention is based is to provide a construction that is simple in structure for the parallel guidance of the knives to each other to create the high requirements in terms of exact guidance of the knife has grown. This object is achieved in that on the lower Knife a lower cross bar is provided, with the upper end of each rod in a ball bearing is performed, which are attached to the upper crossbar of the upper knife.
Die erfindungsgemäße Vorrichtung hat den Vorteil, daß die besondere Art der Parallelführung der Messer während ihrer kreisenden Bewegungen eine besonders genaue Parallelführung gewährleistet, was damit zusammenhängt, daß verhältnismäßig lange Führungsflächen vorgesehen werden können, so daß das für die Gleitbewegung zwischen dem einen Ende der jeweiligen Stange und dem zugehörigen Kugellager erforderliche Spiel nur ganz geringe Kippbewegungen der Messerschneiden gegeneinander wegen der langen Hebelarme zuläßt. Diese Kippbewegungen sind wesentlich geringer als diejenigen, die bei den bekannten, für die Parallelführung dienenden Zahnräderübersetzungsgetrieben auftreten, und dies um so eher, weil nur eine einzige Stelle an den Führungselementen mit Spiel vorgesehen zu werden braucht, nämlich die Stelle am oberen Balken bei dem dortigen Kugellager. Schließlich ist die Vorrichtung gemäß der Erfindung, die das Parallelführen der Messer gewährleistet, viel einfacher als das bekannte Übersetzungsgetriebe aufgebaut.The device according to the invention has the advantage that the special type of parallel guidance of the Knife ensures a particularly precise parallel guidance during their circular movements, what related to the fact that relatively long guide surfaces can be provided so that that for the sliding movement between one end of the respective rod and the associated ball bearing required play only very small tilting movements of the knife edges against each other because of the long lever arms. These tilting movements are much smaller than those which occur in the known gear reduction gears used for parallel guidance, And all the more so because only a single point to be provided on the guide elements with play needs, namely the point on the upper beam at the ball bearing there. Finally, the device is according to the invention, which ensures the parallel guidance of the knives, much simpler than the known one Transmission gear built up.

im Bereich der Messer in vergrößertem Maßstab und im Schnitt nach der Linie II- II der F i g. 1.in the area of the knife on an enlarged scale and in section along the line II-II of FIG. 1.
Eine Papierbahn W, die in der durch die Pfeile angegebenen Richtung läuft, gleitet zwischen einer Zugwalze 1 und einer Druckwalze 2 hindurch.A paper web W running in the direction indicated by the arrows slides between a draw roller 1 and a pressure roller 2.
Im besonderen sind über und unter der Zuführungslinie der Materialbahn W Paare von Triebrädern 10 und 13 angeordnet. Diese Triebräder stehen miteinander im Eingriff, das Triebrad 13 wird von einem Triebrad 30 angetrieben. Exzentrisch und frei drehbar aufgehängt zwischen den Triebrädern 10 ist ein oberer Querbalken 11, der ein oberes Messer 16 trägt, das infolgedessen eine Kreisbahn beschreibt, wenn die Triebräder 10 rotieren.In particular, pairs of drive wheels 10 and 13 are arranged above and below the feed line of the material web W. These drive wheels mesh with one another; the drive wheel 13 is driven by a drive wheel 30. Eccentrically and freely rotatably suspended between the drive wheels 10 is an upper transverse bar 11 which carries an upper knife 16 which consequently describes a circular path when the drive wheels 10 rotate.
Analog ist in den unteren Triebrädern 13 exzentrisch und frei drehbar ein unterer Querbalken 14 angebracht, der ein unteres Messer 15 trägt. Um die Messer 15 und 16 unbedingt parallel zu halten, unabhängig von ihrer rotierenden Bewegung um die Achsen der Triebräder 13 und 10, trägt der untere Querbalken 14 an jedem Ende eine feste Führungsstange 18, die in einem auf dem oberen Querbalken 11 fixierten Kugellagergehäuse 3 gleitbar aufgenommen ist. Wenn die Triebräder 10 und 13 sich synchron bewegen, werden die Messer 15 und 16 in periodischen Zeitabständen in Scherverbindung miteinander gebracht.Similarly, a lower transverse bar 14 is eccentric and freely rotatable in the lower drive wheels 13 attached, which carries a lower knife 15. To keep knives 15 and 16 absolutely parallel, independently of their rotating movement around the axes of the drive wheels 13 and 10, the lower one carries Crossbeam 14 at each end has a fixed guide rod 18 which is in one on the upper crossbeam 11 fixed ball bearing housing 3 is slidably received. When the drive wheels 10 and 13 are synchronized move, the knives 15 and 16 are periodically in shear connection with each other brought.
