NEEDLE SELECTION APPARATUS AND METHOD FOR LATCH NEEDLE WARP KNITTING MACHINE

Description

FIELD OF TECHNOLOGY

[0001] The present disclosure relates to the technical field of warp knitting machines, in particular to a device and a method for needle selection of a latch needle warp knitting machine.

BACKGROUND

[0002] Warp knitted fabrics are fabrics formed through simultaneous loop-forming and mutual looping of one or several groups of warps, parallelly arranged, lapped against a row of knitting needles in a longitudinal direction on a warp knitting machine. Loop-forming elements of the warp knitting machine mainly include a knitting needle, a guide needle, a sinker, etc. At present, all the knitting needles on the warp knitting machine are mounted on a needle bed, and reciprocate up and down along with the needle bed. The existing warp knitting machines have not been provided with a device which is used for needle selection on a single knitting needle and controlling the knitting needle to move up and down independently, and therefore cannot control single or multiple knitting needles to move optionally.

[0003] As a result, a knitting needle selection device which may achieve individual needle selection and automatic needle selection becomes a hot spot and a difficulty of research contents at present.

[0004] At present, a utility model with number CN202688628 U disclosed a knitting warp knitting machine capable of performing automatic needle selection. The utility model is provided with a knitting mechanism and an automatic needle selection device, among which the automatic needle selection device further includes a transmission mechanism and automatic needle selection mechanisms. The automatic needle selection mechanisms are controlled by the transmission mechanism to operate on a linear guide rail to sequentially move to needle pushing members corresponding to bearded needles which do not need work for needle section. After needle selection is completed, a needle pushing plate drives, through the needle pushing member, unselected bearded needles to perform knitting work. When it is necessary to perform needle reselection, only a needle pushing baffle plate is needed to be pushed, so as to reset a selected bearded needle, that is make the selected bearded needle re-enter a working position. The automatic knitting warp knitting machine may achieve automatic needle selection and needle arrangement, shorten preparation time for production, improve working efficiency of workers, and improve production capacity of enterprises.

[0005] Disclosed by the present inventors, the device in the above utility model is applicable to a bearded needle warp knitting machine, which is relatively complex. The knitting needle only has a working state and a non-working state, and in a knitting process, a working knitting needle cannot be further selected, such that a fabric type and a pattern type of knitting are limited. Meanwhile, although the purpose of automatic needle selection is achieved by the above automatic needle selection mechanism, it only achieves needle arrangement before starting to knit rather than controlling the knitting needle to move up and down.

[0006] DE 224 058 C relates to a jacquard warp knitting chair with individually movable chair needles, which differs from the previously known chairs of this type essentially in that the needle group which is determined by the jacquard device does not always have to be returned to its starting position before other needles take action.

[0007] US 3 566 618 A relates to circular warp knitting machines, more particularly to individual needle control means for use with circular warp knitting machines. The object of the invention is to increase the patterns which may be knit on a circular warp knitting machine. To this end, means is provided for individually controlling the raising of the needles so that selected needles are raised to less than the full knitted height

[0008] The present disclosure aims at solving the problems of automatic needle selection and control over up-down moving of a specific knitting needle in the knitting process.
