Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fly dust collector for a loom, and more particularly to a fly dust collector for a loom equipped with a vibration generator.

[0002]

2. Description of the Related Art In a loom being manufactured, warp yarns sent from a yarn beam toward a dropper and a heddle are
Due to the vibration caused by the shedding motion and the engagement of the warp with the dropper and the heddle, a strong vertical impact load and tension act. As a result, a part of the monofilament constituting the warp is separated from the surface of the yarn and scattered as fly cotton. As such a cotton wool collecting means, a method of disposing a porous cotton wool suction pipe below the running area of the warp, or blowing away the cotton wool accumulated on the machine base or floor by compressed air The method is known.

[0003]

[Problems to be Solved by the Invention] Fly cotton is scattered in the air,
Alternatively, the environment of the weaving room is deteriorated by falling and depositing on the floor surface or the machine stand. Further, if weaving is continued with the cotton wool adhered to the surface of the warp, product defects such as warp breakage and weaving defects may occur. Then, the weaving efficiency is lowered by stopping the operation of the loom to repair the defective portion,
Labor saving in the woven process is also hindered. Particularly in high-speed looms such as an air jet loom, the amount of fly waste increases in proportion to the improvement in productivity, and it is required to prevent product defects and deterioration of the weaving environment due to the large amount of fly waste. .. As a solution to this problem, as described in the preceding paragraph, a method of disposing a perforated pipe below the running area of the warp and sucking and collecting the cotton wool or a method of blowing the cotton wool by compressed air has been proposed. However, in either method, it is difficult to adjust the suction pressure and the blow-off pressure, and there are problems that the cotton collecting action is partial and that the blown cotton fly is scattered again. Cotton removal effect is not obtained.

[0004]

As a means for solving the above-mentioned problems, the present invention is to provide a cotton fly generating section between left and right side frames of a loom such that the running direction of the warp and the longitudinal direction of the plate body are substantially orthogonal to each other.
In addition, the wind in which the height of the receiving surface is gradually decreased from the front edge and the rear edge of the plate body toward the central portion so as to form the receiving surface of the fly cotton over substantially the entire alignment width of the warp group. A cotton collecting plate is stretched, and at the lowermost center of the cotton collecting plate, a cotton collecting pipe having a slit for inflow of cotton is opened at the upper end, and at the same time, Provided is a fly dust collecting device in a loom having a vibration generator mounted on the lower surface.

[0005]

[Function] The cotton wool that has dropped onto the cotton wool collecting plate is continuously or intermittently vibrated by the start of the vibration generator, and slides on the upper surface of the cotton wool collecting plate into the cotton wool collecting tube through the slit. It falls and accumulates. The accumulated fly cotton is sucked from the dust collecting tube by the negative pressure suction force of the suction fan, and is collected in the collector body through the cotton collecting duct.
