End-yarn insertion device

Abstract

The invention provides an end yarn insertion device which clamps the end yarn to insert into the internal of knitted fabrics. End yarn insertion device (1) is set on a flat knitting machine for glove (2), with a guide track (23) and a base (31) sliding transitionally along the guide track (23). The base (31) is equipped with a movable object (32) shifting relatively relative to the base (31). Themovable object (32) is equipped with an end yarn hook (33) and an end yarn pressing foot (34). The end yarn hook (33) shifts between the capture position of capture yarn and the hook backoff positionof knitting needle backoff. The end yarn pressing foot (34) acts continuously with the end yarn hook (33), shifting on the clip position where it coordinates with the end yarn hook on the capture position to span support position supporting yarn captured by the end yarn hook and on the pressing foot backoff position where it yields with the knitting needle and the end yarn hook (33). A second driving mechanism (26) drives the end yarn hook (33) to shift between the capture position and the hook backoff position. The base (31) is equipped with a stopper (48). The stopper (48) jams and fixes the end yarn pressing foot(34) shifting from the pressing foot backoff position to the support position to prevent shifting, ensure that the end yarn pressing foot stands by on the stand-by position where the yarn of yarn feeding yields. And the end yarn pressing foot (34) is detached from the stopper (48) by shifting the movable object (32) relatively relative to the base(31).

Description

technical field [0001] The present invention relates to an end yarn inserting device provided on a flat knitting machine for inserting an end yarn into the inner side of a bag-shaped knitted fabric. Background technique [0002] The end yarn inserting device in the prior art moves the end yarn hook and the end yarn presser near the transition yarn when the end yarn is clamped. Next, the end yarn hook and the end yarn presser are swung. At this time, the end yarn hook descends to the catching position for catching the transitional yarn, and the end yarn presser is spaced upward relative to the end yarn hook. In this state, the end yarn of the transition yarn is caught on the end yarn hook. Then, the gripping of the end yarn by the cutting and gripping device is released, and the end yarn hook is raised, and the end yarn of the intermediate yarn is clamped by the end yarn hook and the end yarn presser foot (for example, refer to Patent Document 1).

AI Technical Summary

Problems solved by technology

[0004] In the prior art end yarn inserting device, since the end yarn hook is raised from the catch position to clamp the end yarn, when clamping before the end yarn is released by the cutting and holding device, excess yarn force acts on the knitting yarn, yarn breakage

And when the end yarn is clamped while the cutting and holding device releases the end yarn, the yarn force applied to the end yarn becomes insufficient, and the knitting yarn becomes slack

In addition, there is a case where the end yarn protrudes from the end yarn hook, and thus the insertion of the end yarn into the finger pocket is unstable.
