Abstract

The take-up installation for withdrawing knitted products in flat knitting machines incorporates nozzles downstream along the bottom side of the needle bed. The nozzles generate an air or gaw jet which induces a vacuum in the duct between the needle beds under the knitting needles. the finished product is drawn downstream by an air current and pressed against a transport device. An antistatic agent is added to the air or gas stream and the transport unit consists of a carriage that moves in a vertical or inclined direction. ADVANTAGE - The product is seized near the point of production and transported securely. An existing electric charge is diverted.

Description

Die vorliegende Erfindung betrifft eine Warenabzugsvorrichtung vorzugsweise für Flachstrickmaschinen gemäß dem Oberbegriff des Anspruchs 1.The present invention relates to a goods withdrawal device, preferably for Flat knitting machines according to the preamble of claim 1.

Ein derartiger Warenabzug ist aus der EP 04 21 665 bekannt. Bei dieser Warenabzugsvorrich­ tung erfolgt lediglich ein Erfassen des Gestrickes zwischen den motorisch angetriebenen Abzugswalzen und der relativ große Abstand zur Position der Gestrickerzeugung ist ungünstig. Der notwendige Preßkontakt zwischen der Gestrickware und den Abzugwalzen begünstigt eine für die Verarbeitung störende elektrostatische Aufladung der Strickware.Such a goods deduction is known from EP 04 21 665. With this deduction device device only detects the knitted fabric between the motor-driven take-off rollers and the relatively large distance from the position of the knitted fabric is unfavorable. The necessary Press contact between the knitted fabric and the take-off rollers favors one for processing disruptive electrostatic charging of the knitted fabric.

Es ist Aufgabe der Erfindung, eine Warenabzugsvorrichtung der gattungsgemäßen Art so auszubilden, daß das Gestrick nahe am Entstehungsortes erfaßt und sicher transportiert, sowie eine bereits vorhandene elektrostatische Aufladung abgeleitet wird. Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst. Zweckmäßige Ausgestaltung der Erfindung sind in den Unteransprüchen angegeben.It is an object of the invention to provide a goods take-off device of the generic type to train that the knitted fabric is grasped close to the place of origin and transported safely, as well as a existing electrostatic charge is derived. This object is achieved according to the invention solved by the characterizing features of claim 1. Appropriate design of the Invention are specified in the subclaims.

Durch die abwärts gerichteten Strahldüsen entsteht ein Unterdruck im Strickbettbereich unterhalb der Stricknadeln, so daß der erzeugte Luftstrom auch bei Strickbeginn einen ausreichenden Zug aufweist.The downward-directed jet nozzles create a vacuum in the knitting bed area below the knitting needles, so that the air flow generated is sufficient even at the start of knitting Train.

Die Position der Überdruckdüsen oder die stromabwärts gerichtete Transportvorrichtung gewährleistet, sowohl bei Vollastbetrieb, als auch im Niedriglastbereich durch Zurücknehmen des Düsenstrahldruckes oder Transportzugs eine weitgehend ausreichende Beaufschlagung und Abzugskraft des Gestrickes. Die Öffnungen im Transportschlitten sind mit einer Unterdruckkam­ mer verbunden und gewährleisten die Gestrickehaftung.The position of the pressure nozzles or the downstream transport device guaranteed, both at full load operation and in the low load range by withdrawing the Jet pressure or transport train a largely sufficient exposure and Pull-off force of the knitted fabric. The openings in the transport carriage came with a vacuum more connected and guarantee the knitting adhesion.

Ausführungsbeispiele der Erfindung werden nachfolgend anhand der Zeichnung näher erläutert. Embodiments of the invention are described below with reference to the drawing explained in more detail.
