Description

[Detailed description of the invention] The present invention relates to a static electricity removal device for a loom, and its purpose is to eliminate the static electricity generated in the warp threads during the operation of the loom, thereby reducing the amount of fluff that was unavoidable in the past. The purpose is to effectively eliminate troubles caused by adhesion to warp threads.

As is well known, in a loom, weaving is carried out by inserting weft threads between the warp threads opened for each pick by belt motion, and beating the inserted weft threads in the direction of the weaving front with a reed. In this case, for example, if a filament yarn is used for the warp and a spun yarn is used for the weft, the fluff from the spun will be attracted to the static electricity generated in the warp, causing problems such as poor opening of the warp and warp breakage, resulting in production. This had an unfavorable effect on performance and quality control.

The present invention was developed to eliminate the above-mentioned drawbacks of conventional looms, and it electrically neutralizes and eliminates the static electricity generated in the warp groups, and also eliminates fluff by the wind induced by the node operation. It will scatter.

That is, to explain the present invention based on the illustrated embodiment, belts la and lb are installed on the machine and separate the warp group A into upper and lower openings, and each time the weft is inserted, it is C
A static eliminating member 3 containing conductive fibers is installed at a predetermined position between the threads 2 and the threads 2 that cause beating in the direction so that when the warp group A is separated, it can come into contact with the floating side warp group Au in a crossing shape. In addition, the present invention relates to a static electricity removing device for a loom, characterized in that the static electricity generated in the warp thread group A is neutralized by grounding the static electricity removing member 3.

In the above, the configurations of the belts la, lb and reeds 2 are no different from those employed in conventionally known looms.

The static eliminating member 3 is arranged in a crossing shape in a position that does not obstruct the operation of the belt 1a on the side of the fabric C side and the warp thread group A.
is installed so as to contact the floating side Au when the opening is divided proportionally.

The static eliminating member 3 has a contact portion 31 made of conductive fibers, and is usually configured in the shape of a curtain as shown in the figure.

This is because if the structure is configured in the form of a curtain, the wind induced by the operation of the reed 2 hits the static eliminating member 3 and blows up, effectively scattering the fluff at this time.

As the conductive fibers, well-known metal fibers (for example, stainless steel fibers) or carbon fibers in the form of cloth or string are used.

However, metal fiber and carbon fiber are
It is not necessarily necessary to use it alone, and it is also possible to use it in a blend with other types of fiber materials.

As the means 4 for grounding the static eliminating member 3, a conventionally well-known conducting wire and a grounding electrode (grounding rod, grounding plate, etc.) are used.

Although the device of the present invention is generally constructed as described above, the present invention is by no means limited to the illustrated embodiment;
It goes without saying that various modifications are possible within the scope of the claims for utility model registration.

As explained above, the present invention adopts a configuration in which a static eliminating member is provided at a predetermined position between the belt and the lead, and this static eliminating member is grounded.

Therefore, even if the warp yarn group is charged with static electricity due to friction with various parts during operation, the loom to which the present invention is applied can
When the warp threads are divided into openings and floated up by the belt movement, the static electricity eliminating member comes into contact with them and immediately neutralizes the static electricity, eliminating the possibility of air fluff adhering to the warp threads, or causing them to stick to the warp threads. It is scattered by.

In this way, according to the present invention, it is possible to surprisingly effectively eliminate the harmful effects of fly fluff, which were unavoidable in the past, and the structure is simple and can be applied at low cost, making it practical and economical. It also has many advantages.
