Description

Vorrichtung zum Unterteilen von nachgiebigen Werkstoffbahnen, insbesondere aus Gummi, in dünne, z. B. etwa 1 mm starke Streifen Die Erfindung bezieht sich auf Vorrichtungen zum Unterteilen von nachgiebigen Werkstoffbahnen, insbesondere aus Gummi, in dünne, z. B. i mm starke Streifen aus einander gegenüberliegenden Reihen von beiderseitig scherenartig zusammenarbeitenden umlaufenden. Schneidwerkzeugen und betrifft eine Ausbildung der Schneidwerkzeuge, durch die ein gleichmäßiges axiales Anpressen der SchneidLanten, das zur Herbeiführung der erforderlichen - Scherwirkung nötig ist, mit Sicherheit gewährleistet sein soll.Device for dividing flexible material webs, in particular made of rubber, in thin, z. B. about 1 mm thick strips The invention relates on devices for dividing flexible material webs, in particular made of rubber, in thin, z. B. i mm thick strips of opposite one another Rows of rotating scissors-like working together on both sides. Cutting tools and relates to a design of the cutting tools through which a uniform axial Pressing the cutting edge to bring about the necessary - shear effect is necessary, should be guaranteed with certainty.

Das Wesen der Erfindung ist darin zu erblicken, daß zwischen den umlaufenden Schneidwerkzeugen elastische Scheiben aus Gummi eingelagert und die einzelnen Werkzeugreihen ein- öder beiderseitig in nachstellbaren Widerlagern eingespannt sind, Die Wahl der elastischen Zwischenscheiben aus Gummi soll gegenüber den bekannten Einrichtungen, bei welchen die Messerscheiben durch Spannungsfedern im. Abstand voneinander gehalten werden, deh - Vorteil eines gleichmäßigeren Anpressungsdruckes über die gesamte Vorrichtungsbreite haben, da Gummi wesentlich leichter als Metallfedern auf kleine Druckschwankungen anspricht. Insbesondere aber sollen erst diese Zwischenlagscheiben aus Gummi das Herstellen gleichmäßiger dünner Streifen von etwa i mm Stärke ermöglichen, da Federn bei einem derartig geringen Abstand der. Messerblätter versagen, jedenfalls sich nicht mit einer solchen Genauigkeit herstellen lassen, wie es für ein gutes Arbeiten der Maschine notwendig ist. Diese bei der Anwendung von Metallfedern auftretenden Schwierigkeiten sollen durch die Verwendung von Gummischeiben behoben werden. Außerdem ist die neue Schneidvorrichtung wesentlich einfacher im Aufbau und billiger- in der Herstellung. Durch das Anordnen von als Spannschlössern mit Rechtsund-Linksgewinde ausgebildeten Widerlagern für die Messerscheiben können diese leicht, schnell und äußerst fein eingestellt werden.The essence of the invention can be seen in the fact that between the encircling Cutting tools embedded elastic discs made of rubber and the individual rows of tools one or both sides are clamped in adjustable abutments, the choice the elastic rubber washers should be compared to the known devices, in which the cutter disks by tension springs in. Maintained distance from each other become, deh - advantage of a more even contact pressure over the entire Device width, since rubber is much lighter than metal springs on small ones Responds to pressure fluctuations. In particular, however, these spacer washers should first enable the production of even, thin strips of about 1 mm thick from rubber, because springs at such a small distance the. Knife blades fail, at least cannot be made with such precision as is good Work of the machine is necessary. This occurs when using metal springs Difficulties are to be eliminated through the use of rubber washers. aside from that the new cutting device is much simpler in construction and cheaper in the production. By arranging as turnbuckles with right and left-hand threads trained abutments for the cutter disks, these can be done easily, quickly and can be adjusted extremely finely.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt.An embodiment of the invention is shown in the drawing.

In dieser veranschaulicht Fig. i eine im wesentlichen schematisch gehaltene Vorderansicht und Fig. z einen Schnitt durch die Anordnung der Schneidscheiben in größerem Maßstab. Wie aus Fig. i ersichtlich, besteht das Schneidgerät aus zwei gegenüberliegenden Reihen i, a von Schneidwerkzeugen 3, die bei 4 scherenartig ineinandergreifen und auf Tragachsen 5, 6 angeordnet sind. Die' Tragachsen ruhen beiderseitig in Lagerböcken 7, 8 und können von einem Motor 9 über ein Reduktionsgetriebe i o und die Stirnräder t i angetrieben werden.In this Fig. I illustrates one essentially schematically The front view and FIG. z shows a section through the arrangement of the cutting disks on a larger scale. As can be seen from Fig. I, the cutting device consists of two opposite rows i, a of cutting tools 3, which at 4 interlock like scissors and up Support axles 5, 6 are arranged. The 'supporting axles rest on both sides in bearing blocks 7, 8 and can from a motor 9 via a reduction gear i o and the spur gears t i are driven.

Die Schneidwerkzeuge bestehen aus .einzelnen Schneidscheiben 3, die beiderseitig mit Schneidkanten 3a, 3b versehen sind und an der Schneidstelle 4., sich zum Teil überdeckend, aneinanderliegen, so daß die Breite der anfallenden Streifen oder Bänder der Breite der Scheiben entspricht.The cutting tools consist of .individual cutting disks 3, which are provided with cutting edges 3a, 3b on both sides and at the cutting point 4., partially overlapping each other, so that the width of the resulting strips or bands corresponding to the width of the slices.

Erfindungsgemäß sind zwischen den benachbarten Schneidscheiben Zwischenlagplatten 12 (Fig. 2) aus Gummi eingefügt, deren Durchmesser geringer ist als der der Schneidscheiben:. Durch das Einschalten dieser Abstandsplatten werden die Reihen der Schneidscheiben federnd gehalten, so daß die zusammenarbeitenden Schneidkanten ständig wie die Schneidschenkel einer Schere zusammenwirken, wenn die Scheiben umlaufen und eine Werkstoffbahn zwischen ihnen hindurchgeleitet wird.According to the invention, spacer plates are between the adjacent cutting disks 12 (Fig. 2) made of rubber, the diameter of which is smaller than that of the cutting discs :. By turning on these spacer plates, the rows of cutting disks resiliently held so that the cooperating cutting edges constantly like the cutting legs a pair of scissors work together when the discs rotate and a material web between is passed through them.

Zum Herbeiführen des erforderlichen Preßdruckes dienen an den einzelnen Schneidscheibenreihen vorgesehene Spannschlösser 13, die zwischen den Scheiben und den die Lagerung für die Welle bildenden Schublagern 14 eingebaut sind.To bring about the necessary pressure are used on the individual Rows of cutting disks provided turnbuckles 13, which between the disks and the thrust bearings 14 forming the bearing for the shaft are installed.

Um die Scheiben der zusammenwirkenden Reihen gegeneinander ausrichten zu können, ist es erforderlich, daß wenigstens das zur Herbeiführung des axialen Preßdruckes dienende Widerlager einer der Schneidscheibenreihen nachstellbar ist. Dies wird bei dem dargestellten Ausführungsbeispiel dadurch erreicht, daß beiderseits der Schneidmesserreihen Spannschlösser vorgesehen sind, die zur Herbeiführung des Preßdruckes und/oder als verstellbares Widerlager dienen. Gegebenenfalls bann aber eines der Spannschlösser einer Reihe durch ein festes, unverstellbares Widerlager ersetzt werden.To align the discs of the cooperating rows against each other to be able to, it is necessary that at least that to bring about the axial Pressing pressure serving abutment of one of the rows of cutting disks is adjustable. This is achieved in the illustrated embodiment in that both sides of the cutting knife rows turnbuckles are provided, which are used to bring about the Press pressure and / or serve as an adjustable abutment. If necessary, however, ban one of the turnbuckles in a row by a fixed, non-adjustable abutment be replaced.

Die Trennscheiben 12 werden zweckmäßig als glatte ringförmige Gummischeiben ausgebildet. Sie können jedoch auch jede andere Form haben oder aus einem anderen nachgiebigen, elastischen Werkstoff gefertigt sein, welcher die notwendige Nachgiebigkeit zwischen den einzelnen Schneidscheiben liefert. Gegebenenfalls können die Scheiben 12 zur Erhöhung der Nachgiebigkeit mit Aussparungen oder Durchbrechungen versehen sein.The cutting disks 12 are expediently as smooth, annular rubber disks educated. However, they can also have any other shape or from another compliant, elastic material, which has the necessary flexibility between the individual cutting disks. Optionally, the disks 12 provided with recesses or perforations to increase the flexibility be.
