Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for arranging healds in a heald frame which can improve the operating rate of a loom and can effectively reduce the noise of the loom.

[0002]

2. Description of the Related Art In a heald frame, a heald is held between upper and lower frame stews via a carrier rod.

[0003] That is, the heald is mounted between the upper and lower frame steaves by inserting a carrier rod into an opening formed at the end. The heald is
It is movable along the carrier rod, and is allowed to move up and down slightly through the opening.

[0004]

According to the prior art, since the heald is allowed to move up and down through the opening, one end of the opening hits the carrier rod during the opening operation. A loud impact sound is generated,
In addition to being a major factor in loom noise during high-speed operation,
There is a problem that the heald and the carrier rod are worn out early. In addition, since the healds are movable along the carrier rod, they are inclined between the frame staves, or are closely adhered to each other by warp sizing agent or water for weft insertion in the water jet loom, causing a bridging phenomenon in the warp. Or warps entangle with each other due to static electricity,
There is also a problem that the weaving operation may be hindered.

SUMMARY OF THE INVENTION In view of the above-mentioned problems in the prior art, the object of the present invention is to reduce the noise of the loom caused by the shedding operation by using a magnet that magnetizes the end of the heald, and to reduce the heald on the carrier rod. It is an object of the present invention to provide a device for arranging healds in a heddle frame, which can neatly arrange the healds.

[0006]

In order to achieve the above object, according to the present invention, a magnet having magnetic poles at the front and rear is disposed along a frame steve. The gist is to magnetize.

The magnet may be provided with a reinforcing material, and the reinforcing material may be a ferromagnetic material.

[0008] The magnet can be mounted on a frame steve. The magnet may be attached to the frame steve via a holder, or may be attached to the frame steve via a middle hook.

Furthermore, the magnet can be provided corresponding to a heald which is divided and arranged in the longitudinal direction of the frame steve.

[0010] The heald may be arranged along the upper and lower frame steaves.

[0011]

According to the structure of the present invention, since the magnet is disposed along the frame steve and has the magnetic poles in front and back, the end of the heald can be magnetized back and forth.
The healds on the carrier rod can be arranged neatly separated from one another. This is because the healds are magnetized to the same polarity back and forth by the magnetic flux from the magnet and repel each other. The magnet also attracts the heald to the frame stave side and suppresses the heald from moving up and down, thereby preventing the relative speed of the heald with respect to the carrier rod from becoming excessive during the opening movement, and reducing the impact noise caused by the opening movement. Can be greatly reduced.

When a reinforcing material is attached to the magnet, the reinforcing material increases the strength of the magnet and prevents breakage of the magnet.

If the reinforcing material is a ferromagnetic material, the reinforcing material can further increase the magnetic flux density at the end of the heald.

If the magnet is mounted on the frame steve, the magnet can be easily applied regardless of the type of the frame steve.

[0015] If the magnet is mounted on the frame steve via the holder, the holder can position the magnet sufficiently close to the end of the heald and the end of the heald can be more strongly magnetized.

When the magnet is mounted via the middle hook, the middle hook can hold the magnet together with the carrier rod, and it is not necessary to use a special holder for holding the magnet.

When providing a magnet corresponding to the heald,
The magnet may be provided over a minimum necessary range, and an increase in the weight of the heald frame can be minimized.

By arranging the magnets along the upper and lower frame staves, the upper and lower magnets can simultaneously magnetize both ends of the heald, thereby more reliably preventing the heald adhesion phenomenon due to the warp glue or the like. be able to.
