Yarn feeding device for knitting machine

Abstract

The present invention provides a yarn feeding device which has action when feeding yarn is not intervened with a needle dish, is movable and minimized, and can operating more yarn feeding the same as single needle knitting machine. The yarn guide mechanism comprises a needle selecting plate activated by an actuator selection; a finger shaped plate making the projecting piece in or out in the finger shaped plate moving cam by using the action of the needle selecting plate and deflecting by the cam; a cutting plate swinging taking a support as center freely is supported on a side plate, and having pivot connected on the finger shaped plate and swinging along the deflection of the same; a broken yarn holding member having fixed blade, movable blade, yarn pressing plate and a rotation hammer activating the movable blade relatively fixating blade; said yarn guide mechanism is arranged on the needle array of the needle cylinder needle in terms of the swinging direction of the cutting plate is vertical with the needle array of the needle cylinder needle.

Description

technical field [0001] The invention relates to a yarn feeding device in a circular knitting machine. Background technique [0002] Circular knitting machines are roughly divided into two types: dial cylinder knitting machines and single needle knitting machines, but they are all equipped with unit yarn feeding devices at multiple positions around the cylinder, and each unit yarn feeding device holds multiple yarns. For the yarn, the appropriate yarn is selected corresponding to the pattern of the knitted fabric to be formed, and guided to the yarn feeding position to feed the yarn to weave the knitted fabric. [0003] Each of the above-mentioned unit yarn feeding devices selects the yarn guide arm that holds the predetermined main yarn among the plurality of yarn guide arms that are separately provided, and moves the held yarn to the knitting position. The yarn guiding arm of the machine retreats to make the yarn retreat from the knitting position. [0004] Here, accordin...

AI Technical Summary

Problems solved by technology

[0004] Here, according to the yarn feeding device of the conventional dial needle cylinder knitting machine, when feeding the yarn, since the dial needle is detoured to feed the yarn, the movement of the yarn guide arm and the interference of the dial needle are avoided. Therefore, it is necessary to move the yarn feeding parts such as the swing arm in an arc shape to avoid the knitting part of the knitting machine as much as possible. From the perspective of the device, a large stroke is required, and there is a shortcoming of the overall size of the knitting machine (refer to Patent Document 1 )

In addition, the fact that the device is enlarged also limits the types of yarn feeding
