{SWING GUIDE APPARATUS FOR SHEDDING MOTION IN LENO HEAD LOOM}

The present invention relates to a lenoheald loom, and in particular, guides the reciprocating opening movement of a lenoheald loom that can extend the life of healds that undergo repetitive opening movements in a lenoheald loom in the form of a set of two heald frames to have a lenostructure. It's about devices.

In general, fabric weaving is done using a loom, and the fabric is woven through an opening device, a feeding device, a body needle device, and a feeding and winding device configured on the loom, and an opening device using heald depending on the fabric or tissue structure to be woven. changes.

For example, in order to weave leno fabric, an opening device for leno heald is provided on the loom. To weave leno fabrics on looms such as water jet looms, air jet looms, Repia looms, or dobby looms, leno healds are connected to two heald frames, and then the leno healds are operated to create two strands centered on the placed weft. Weaving progresses as the warp yarns are twisted together.

In other words, in the leno structure, the warp yarns are divided into two types, A and B. One of them, warp yarn A, intersects the weft in a straight line like in an ordinary fabric, but the remaining warp warp B regularly goes back and forth to the left and right of warp A, connecting the warp and weft yarns. It's entangled. Therefore, because the position of warp B changes left and right with respect to warp A, warp A is called the ground warp, and warp B is called the wing warp.

Therefore, as shown in Figure 1, in the weaving of leno tissue, in addition to the lift healds (2) and (4) on one side and the other, which are ordinary healds, there are V-shaped healds (6) called doup healds. (hereinafter referred to as ‘V healing light’) is required.

Referring to Figure 1, in the configuration of the Leno heald, the lift healds (2) (4) and V healds (6) on both sides are plate-shaped, of which the lift healds (2) (4) on both sides are made of resin, and the V healds (6) are made of resin. ) mainly uses metal materials.

Numerous one-side lift healds (2) are arrayed and mounted on the one-side heald frame (8) via upper and lower pole-type supports at the upper and lower ears. In addition, numerous other side lift healds (4) are arranged and mounted on the other side heald frame (10) via upper and lower pole-type supports at the upper and lower ears.

Both legs 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 a pole-type hanging bar is inserted into the ends of both legs of the V heald (6), and the hanging bar hanger is A leno heald is constructed by installing an elastic spring (14), which is a tension adjustment device, at (12).

In addition, as shown in Figure 1, a warp A, called a ground warp, is threaded through the waist space of the lift healds 2 and 4 on one side and the other, and a warp warp is threaded through the eye of the V healt 6. The warp B, called a (doup warp), is threaded through, and the lift healds (2) and (4) on one side and the other side are lifted up or down by the Leno heald opening device, forming a V heald. The warp yarn B threaded through the eye of (6) goes back and forth to the left and right of the warp thread A threaded through the space on the waist side of the lift healds (2) and (4) on both sides, entangling the warp and weft threads to form a Leno tissue.

As shown in Figure 1, in constructing the leno heald of the opening device for leno heald, which consists of two heald frames (8) and (10), the V heald (6) is attached to the waist of the lift healds (2) (4) on both sides. A plurality of elastic springs (14) are installed through and are held in common at both leg ends of the V heald (6) along the length of the heald frames (8) and (10) on both sides (heald frame length 1800 mm to 4500 mm). Configure it so that appropriate tension can be adjusted on the V heald (6).

However, it is realistically difficult for the plurality of elastic springs 14 arranged along the longitudinal direction of the heald frames 8 and 10 to all have the same elastic force, and even if so, a plurality of elastic springs 14 with the same elastic force were initially installed together. Even if the elastic force changes during use, the elastic force of the plurality of elastic springs 14 arranged in the longitudinal direction of the heald frame 8 and 10 is not uniform.

Therefore, the tension of the numerous V healds (6) arranged along the longitudinal direction of the heald frame (8) (10) is not uniform, so the V healds (6) made of metal are lifted on both sides of the lift healds (2) (4) made of resin. ), the lifespan of the lift healds (2) and (4) on both sides made of resin are shortened due to impact wear and friction wear. This phenomenon of uneven tension of the V healts (6) arranged in the longitudinal direction of the heald frame (8) (10) appears more significantly when the speed of the Leno heald opening movement is increased.

The resin-based healds that make up leno healds are usually installed in hundreds to thousands of heald frames, so if each heald is in the thousands of won range, the replacement cost alone ranges from tens to millions of won.

Therefore, if the pulling uniformity of the V healds (6) arranged in the longitudinal direction of the heald frame (8) (10) can be ensured, the speed of opening movement of the lenoheald can be improved and the lifespan of the lenoheald can be extended. Therefore, improvement measures are needed.
