Description

Fadenschneidvorrichtung an Rundstrickmaschinen Die Erfindung bezieht sich auf eine Fadenschneidvorrichtung an Rundstrickmaschinen zum Abschneiden überschüssiger Wechselfäden und/oder flottliegender Verstärkungsfäden mit mindestens einem beweglichen mehrzinkigen Scherenblatt, das mit einem hin- und hergehenden Antrieb verbunden ist.Thread cutting device on circular knitting machines The invention relates to on a thread cutting device on circular knitting machines to cut off excess Alternating threads and / or floating reinforcing threads with at least one movable multi-pronged scissor blade connected to a reciprocating drive is.

Mit diesem Vorschlag einer Ausführungsform kann jedoch nur in einer senkrechten Ebene geschnitten werden. Es ist jedoch erwünscht, an der Stirnseite einer Rundstrickmaschine zu schneiden, da dann keine zusätzliche Bewegung der Nadeln erforderlich ist. Dabei wird dann die Schneidvorrichtung von oben innerhalb des Nadelkranzes an den Schneidort herangeführt. Dies ist aber nur möglich, wenn die Schneidvorrichtung einerseits im Aufbau einfach gestaltet und andererseits räumlich auf kleinste Ab- messungen beschränkt ist.With this proposal of an embodiment, however, it is only possible to cut in a vertical plane. However, it is desirable to cut on the face of a circular knitting machine, since then no additional movement of the needles is required. The cutting device is then brought to the cutting location from above inside the needle roller assembly. This is only possible if the cutting device on the one hand in a simple, structure and also spatially smallest exhaust measurements is limited.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß das bewegliche Scherenblatt mit seinem Arm um den ortsfest am feststehenden Scherenblatt gelagerten Bolzen schwingbar angeordnet und über einen Hebel mit dem Antrieb verbunden ist.This object is achieved in that the movable Scissor blade with his arm around the fixedly mounted scissor blade Bolt is arranged to swing and connected to the drive via a lever.

Mit einer solchen Schneidvorrichtung ist es möglich, in einer waagerechten Ebene zu schneiden, so daß man bei einer Rundstrickmaschine die günstigste Anbringungsmöglichkeit dieser Schneidvorrichtung wählen kann.With such a cutting device, it is possible in a horizontal To cut level, so that you can use the most favorable attachment option on a circular knitting machine this cutting device can choose.

Zwar ist es bereits bekannt, zum Abschneiden derartiger Fäden mehrzinkige Schurmesser zu verwenden. Diese sind jedoch nicht an einer Rundstrickmaschine selbst angebracht, sondern werden entweder als Handschneidvorrichtung an den Faden herangeführt, oder aber sie sind an einer besonderen Abschneid- und Prüfmaschine angeordnet. Das Ziel der vorliegenden Erfindung ist es jedoch, derartige Messer an einer Rundstrickmaschine so anzuordnen, daß die überschüssigen Fäden unmittelbar an der Maschine mechanisch abgeschnitten werden.Although it is already known to cut such threads multi-pronged Shear knives to use. However, these are not on a circular knitting machine itself attached, but are either brought up to the thread as a manual cutting device, or they are arranged on a special cutting and testing machine. That However, the aim of the present invention is to provide such knives on a circular knitting machine to be arranged so that the excess threads mechanically directly on the machine be cut off.

Die Zeichnung zeigt ein Ausführungsbeispiel der Erfindung, und zwar eine Seitenansicht einer Fadenschneidvorrichtung.The drawing shows an embodiment of the invention, namely a side view of a thread cutting device.

Am feststehenden Scherenblatt 8 ist um einen ortsfest gelagerten Bolzen 3 mit seinem Arm 2 schwingbar ein bewegliches Scherenblatt 1- angeordnet, wobei beide Scherenblätter 1, 8 mit mehreren Zinken 11 versehen sind, die gehärtete und geschliffene Schneidkanten auf beiden Seiten aufweisen. Dabei ist das feststehende Scherenblatt 8 mittels eines Trägers 7 am Maschinengestell 10 befestigt. Der Antrieb des beweglichen Scherenblattes 1 erfolgt über den mit seinem Arm verbundenen Hebel 4, der ebenfalls am Bolzen 3 gelagert ist. Der Hebel 4 ist mit einem Schlitz 5 versehen, in dem ein Antriebszapfen 6 längsverschiebbar gelagert ist. Der Antriebszapfen 6 ist exzentrisch auf der Achse des Motors 9 befestigt.On the fixed scissor blade 8 a movable scissor blade 1 is arranged swingably around a fixedly mounted bolt 3 with its arm 2, both scissor blades 1, 8 being provided with several prongs 11 which have hardened and ground cutting edges on both sides. The fixed scissor blade 8 is attached to the machine frame 10 by means of a carrier 7. The movable scissor blade 1 is driven via the lever 4 connected to its arm, which is also mounted on the bolt 3. The lever 4 is provided with a slot 5 in which a drive pin 6 is mounted so as to be longitudinally displaceable. The drive pin 6 is fastened eccentrically on the axis of the motor 9.

Beim Umlauf des Motors 9 rotiert der Zapfen 6 und gleitet dabei im Schlitz 5 des Hebels 4 hin und her, so daß der Hebel 4 eine Pendelbewegung ausführt, die auf das bewegliche Scherenblatt 1 übertragen wird.As the motor 9 rotates, the pin 6 rotates and slides back and forth in the slot 5 of the lever 4, so that the lever 4 performs a pendulum movement which is transmitted to the movable scissor blade 1.
