Circular knitting machine transfer pickup device and pickup method

Abstract

The invention discloses a circular knitting machine transferring and picking device and method, the circular knitting machine transferring and picking device comprises a sleeving assembly, a grabbing assembly is arranged below the sleeving assembly, and the sleeving assembly and the grabbing assembly are arranged in a concentric circle mode; the sleeving assembly and the grabbing assembly are provided with a plurality of sleeving needles and grabbing pieces which are correspondingly matched and can move in the radial direction respectively, and an axial driving device for driving the sleeving assembly and the grabbing assembly to move up and down relatively is arranged between the sleeving assembly and the grabbing assembly. The grabbing assembly capable of moving up and down in the axial direction is arranged below the sleeving and taking assembly, and after the hosiery fabric is woven, the lower grabbing piece is matched with the sleeving and taking needle through axial and radial movement to separate and transfer the coil from the knitting needle. Through cooperation of the grabbing pieces, a coil is separated from a knitting needle and transferred to the outside of the V-shaped semi-closed ring of the sleeving and taking needle and is firmly grabbed and fixed through the grabbing pieces, the knitting coil can be prevented from being accidentally separated in the transferring process, and it is ensured that the transferring process is stable and operation is reliable.

Description

technical field [0001] The invention relates to the technical field of circular knitting machinery, especially hosiery knitting machines, and more specifically relates to a circular knitting machine transfer pick-up device and a pick-up method. Background technique [0002] In the field of production of knitted articles on hosiery machines or similar circular knitting machines, it is necessary to transfer the article from the machine used to produce the article to another production unit in order to perform further operations on the article that cannot be carried out on said machine Work performed or performed on said machine is not economically convenient. [0003] In particular, in the field of hosiery production, methods have been developed in recent years to automatically perform the closing of the toe thereof by sewing or looping. Some of these methods are based on picking up the article from the machine used to produce the article and transferring it to a station sepa...

AI Technical Summary

Problems solved by technology

[0005] At present, the technology of transferring the pick-up device is basically complicated in structure. When picking up the product, it is necessary for the hosiery machine to leave enough axial space for the pick-up device to enter.

In order to leave enough axial space for the pick-up device to enter, the yarn feeder disc and the machine head must be raised very high, which not only makes the structure of the machine complicated but also causes entanglement between adjacent yarns, affecting the next work

At the same time, the knitting needle will deform after being used for a period of time, resulting in an error in the radial position of the needle cylinder, and causing problems such as missed knitting loops when grasping.
