Description
Verfahren zum Schneiden von Blättern bestimmter Länge aus Bahnen Bei Zerschneidung von Bahnen in Blättern bestimmter Länge benutzt man bisher zum Transport Walzen. zwischen denen die Bahnen bewegt werden. Beim Gebrauch solcher Walzen läßt sich ein gewisser Schlupf nicht vermeiden, so daß die gewünschten Längen nicht genau eingehalten werden können. Da (las nochmalige Maßschneiden der Blätter große Kosten verursacht, werden aber große Genauigkeitsgrade verlangt.Method for cutting sheets of a certain length from webs Bei Cutting of webs into sheets of a certain length has been used for transport up to now Rollers. between which the tracks are moved. When using such rollers leaves A certain amount of slippage cannot be avoided, so that the desired lengths are not exactly can be complied with. Then (read again cutting the leaves to size at great expense causes, but high degrees of accuracy are required.
Gemäß der Erfindung wird jeder Schlupf der Bahn dadurch vermieden, daß sie zwischen eine Trommel und ein diese auf dem größten Teil ihres Umfanges umschlingendes Band geführt und, während sie so festgehalten wird, durch ein in der Trommel angeordnetes Messer durchschnitten wird. Da die Bahn zwischen der Trommel, die zweckmäßig mit einem elastischen Belag versehen ist, und dem sie umschließenden Band, das aus elastischem Stoff, wie z. B. Kautschuk, Leder, Filzgewebe o. dgl., hergestellt ist, in seiner Lage straff festgehalten wird, ist ein Schlupf praktisch ausgeschlossen. Die Länge der abgeschnittenen Blätter ist gleich dem Trommelumfang, sie kann also sehr genau bestimmt «-erden.According to the invention, any slippage of the web is avoided by that it is between a drum and a drum on most of its circumference looping band and, while it is held in place, through an in the drum arranged knife is cut. As the path between the drum, which is expediently provided with an elastic covering, and which it encloses Tape made of elastic material, such as B. rubber, leather, felt fabric or the like., is made, is held tightly in its position, a slip is practical locked out. The length of the cut sheets is equal to the drum circumference, it can therefore be very precisely determined.
Gegebenenfalls wird die Trommel polygonal ausgebildet und in jeder Ecke radial ein Messer angeordnet. Stehen diese Messer unter der Einwirkung eines an sich bekannten, feststehenden Nockens, so wird immer an derselben Stelle ein Messer vorgestoßen, so daß es ein Blatt abtrennt in der -Länge einer Polygonseite. Die polygonale Trommel kann auch so ausgebildet sein, daß die Ecken radial verschoben werden können, wodurch die Kantenlänge des Polygons verändert wird. Die Verstellung der Polygonecken kann in beliebiger Weise erfolgen, z. B. ebenso wie die Einstellung der Messer bei verstellbaren Reibahlen. Die Kantenlänge und damit die Länge der abgeschnittenen Blätter kann dann auf einer Skala abgelesen werden. Die Blattlänge kann auch dadurch verändert werden, daß Tromineln mit verschiedenem Durchmesser angeordnet werden oder daß über die Trommel ein Mantel geschoben wird. Die beweglichen Messer müssen in diesem Falle in ihrer Länge veränderlich sein.Optionally, the drum is polygonal and in each Radially arranged corner a knife. Are these knives under the influence of a well-known, fixed cam, then a is always in the same place Knife pushed forward so that it cuts off a sheet the length of a polygon side. The polygonal drum can also be designed so that the corners are displaced radially can be changed, whereby the edge length of the polygon is changed. The adjustment the polygon corners can be made in any way, e.g. B. as well as the setting the knife with adjustable reamers. The edge length and thus the length of the cut leaves can then be read off on a scale. The leaf length can also be changed by using tumblers with different diameters be arranged or that a jacket is pushed over the drum. The moving ones In this case, the length of the knife must be variable.
Die Form der Messer ist beliebig. Sie können gerade, abgeschrägt oder auch gezähnt sein oder eine andere geeignete Form haben.The shape of the knife is arbitrary. They can be straight, or beveled also be toothed or have some other suitable shape.
Auf der Zeichnung sind Ausführungsbeispiele von Vorrichtungen dargestellt, die zur Ausführung des Verfahrens dienen.In the drawing, exemplary embodiments of devices are shown, which are used to carry out the procedure.
Abb. i zeigt eine Trommel von Kreisquerschnitt mit einem Messer, Abb. 2 eine polygonale Trommel mit mehreren Messern und Abb. 3 eine polygonale Trommel mit verstellbaren Ecken. Die Messer sind der Deutlichkeit halber bei dieser Trommel nicht eingezeichnet.Fig.i shows a drum of circular cross-section with a knife, Fig. 2 a polygonal drum with several knives and fig. 3 a polygonal drum with adjustable corners. The knives are on this drum for the sake of clarity not shown.
Die Trommel a (Abb. i ) läuft um eine Achse b im Sinne des Pfeiles c um. Ein endloses Band d, das um Rollen c gelegt ist, umschlingt die Trommel a auf dem größten Teil ihres Umfanges. In der Trommel a ist das bewegliche Messer f angeordnet, das unter dem Druck einer Feder g gegen eine feststehende Nockenscheibe la gedrückt wird. Die zu zerschneidende Bahn i wird zwischen Trommel a und Band d eingeführt. Erreicht die Trommel die gezeichnete Stellung, in der der Nocken la in Tätigkeit tritt, so wird das Messer f hervorgeschnellt und zerschneidet die Bahn. Das abgeschnittene Blatt J, tritt dann zwischen Trommel a und Band d an der andern Seite wieder aus.The drum a (Fig. I) revolves around an axis b in the direction of arrow c. An endless belt d, which is placed around rollers c, wraps around the drum a over most of its circumference. In the drum a, the movable knife f is arranged, which is pressed under the pressure of a spring g against a fixed cam disk la. The web i to be cut is introduced between drum a and belt d . When the drum reaches the position shown in which the cam la comes into action, the knife f is flicked out and cuts the web. The cut sheet J then exits between drum a and belt d on the other side.
Bei der polygonalen Trommel a1 (Abb. 2) sind sechs Messer f angeordnet, die sämtlich unter dem Einfluß des Nockens 1a stehen. Läuft die Trommel um, so tritt jedes Messer in Tätigkeit, wenn es (bei dem dargestellten Beispiel) die 6o°-Stellung erreicht hat.With the polygonal drum a1 (Fig. 2) six knives f are arranged, all of which are under the influence of the cam 1a. If the drum rotates, kick every knife in action when it is in the 60 ° position (in the example shown) has reached.
Die übrigen Teile unterscheiden sich nicht von den Teilen der Vorrichtung nach Abb. i. Bei der Ausführung nach Abb. 3 sind die Ecken l im Trommelkörper a., radial beweglich. Sie legen sich beispielsweise mit Ansätzen in gegen eine verstellbare Daumenscheibe ri.. Das Band d wird bei dieser Ausführung um eine Ausgleichsrolle o geführt, so daß es immer straft bleibt. Bei sämtlichen Ausführungen sind natürlich Spannrollen o. dgl. vorgesehen, die die Spannung des elastischen Bandes regeln.The other parts do not differ from the parts of the device according to Fig. I. In the embodiment according to Fig. 3, the corners l in the drum body a., Are radially movable. You lay down, for example, with approaches in against an adjustable thumb disk ri .. In this embodiment, the band d is guided around a compensating roller o so that it is always punctured. In all designs, of course, tension rollers or the like are provided that regulate the tension of the elastic band.
Selbstverständlich ist die Anwendung des Verfahrens nicht auf die Benutzung der dargestellten Vorrichtungen beschränkt. Es kann vielmehr auch mit beliebigen andern geeigneten Vorrichtungen ausgeführt werden.Of course, the application of the procedure is not to that Use of the devices shown is limited. Rather, it can with any other suitable device can be carried out.
