Description

Opening motion reciprocating guide device of Leno heald loom {SWING GUIDE APPARATUS FOR SHEDDING MOTION IN LENO HEAD LOOM}

The present invention relates to a leno heald loom, and particularly, in a leno heald loom in which two heddle frames form a set to have a leno texture, reciprocal guidance of the opening movement of the leno heald loom that can extend the life of a heald that performs repetitive opening motions It's about the device.

In general, weaving of fabrics uses a loom, but fabrics are woven through an opening device, a weft device, a body needle device, and a sending and winding device composed of a loom, and an opening device using a heald depending on the fabric or tissue structure to be weaved. will be different

For example, in order to weave leno fabric, an opening device for leno heald is provided on the loom. In order to weave leno fabric on a loom such as a water jet loom, an air jet loom, a rapier loom or a dobbing machine among looms, the leno heald is connected to two heald frames, and then the leno heald is operated to make two strands centered on the weft thread inserted. Weaving proceeds as the warp yarns are twisted with each other.

In other words, in the leno weave, warp yarns are divided into two types, A and B, and one of them, warp A, intersects the weft in a straight line as in normal fabrics, but the other, warp B, moves to the left and right of warp A regularly and separates the warp and weft. are entangled Therefore, warp A is called ground warp, and warp B is called doup warp, because warp A changes its position from side to side with respect to warp A.

Therefore, in the weaving of leno tissue, as shown in FIG. 1, a V-shaped heald (6) called a doup heald in addition to lift heald (2) (4) on one side and the other side, which are ordinary healds. (hereinafter referred to as 'V curd light') is required.

1, in the configuration of the leno heald, the lift healds (2) (4) and the V heald (6) on both sides are plate-shaped, and the lift healds (2) (4) on both sides are made of resin, and the V heald (6) ) is mainly used for metal materials.

A number of one-side lift healds 2 are arranged and mounted on the one-side heald frame 8, but are mounted on the one-side heald frame 8 via upper and lower jaw-type supports at the ears of the upper and lower ends. In addition, a number of other lift healds 4 are arranged and mounted on the other side heald frame 10, but are mounted on the other side heald frame 10 via upper and lower jaw-type supports at the ears of the upper and lower ends.

The legs of both sides of the V heald (6) are inserted and hung so as to pass through one side of the waist of the two lift healds (2) (4), and the ends of the legs of both sides of the V heald (6) are fitted with a pole-type hanging rod, and the hanging rod hanger By installing an elastic spring 14, which is a tension adjusting device, in (12), a leno heald is constituted.

In addition, as shown in FIG. 1, an inclination A called a ground warp is threaded through the waist space of one and the other lift heald (2) (4), and the eye of the V heald (6) has a ripple A warp B, called a doup warp, is threaded through, and as one and the other lift heald (2) (4) are lifted up or lifted down by an opening device for Leno heald, V heald Warp yarn B, threaded through the eyes of (6), moves left and right of warp yarn A, threaded in the space on the waist side of lift healds (2, 4) on both sides, entangling the warp and weft to form leno tissue.

As shown in FIG. 1, in constructing the Leno heald of the opening device for the Leno heald in which two heald frames 8 and 10 form a pair, the V heald 6 is a leg on the waist of the lift heald 2, 4 on both sides. A plurality of elastic springs 14, which are hooked through and commonly hold the leg ends of both sides of the V heald beam 6, are installed along the length of the heddle frames 8 and 10 on both sides (length of the heald beam 1800 mm to 4500 mm). It is configured so that the tension is properly adjusted to the V hed light (6).

However, it is practically difficult for the plurality of elastic springs 14 arranged along the longitudinal direction of the heddle frames 8 and 10 to have the same elastic force, and even if a plurality of elastic springs 14 having the same elastic force are initially installed together Even though the elastic force changes during use, the elastic force of the plurality of elastic springs 14 disposed in the longitudinal direction of the heddle frames 8 and 10 is not uniform.

Therefore, since the tension of the V healds (6) arranged in large numbers along the longitudinal direction of the heald frames (8) (10) is not uniform, the metal V heald beams (6) are lifted on both sides of the resin material lift healds (2) (4). ) is unnecessary, so the life of the lift healds (2) (4) on both sides of the resin material due to impact wear and friction wear is shortened. The non-uniform tension of the V healds 6 arranged in the longitudinal direction of the heald frames 8 and 10 appears larger when the opening movement of the Leno heald is increased.

Hundreds to thousands of healds made of resin materials constituting a leno heald are usually installed in a heald frame.

Therefore, if the traction uniformity of the V healds 6 arranged in the longitudinal direction of the heald frames 8 and 10 can be ensured, the speed of opening movement of the leno heald can be improved and the life span of the leno heald can be extended. There is a need to improve on that.
