Description

[Detailed Description of the Invention] Industrial Field of Application The present invention relates to a cocoon collector used to draw out cocoon silk from cocoons and bundle it into a single raw silk.

〓Prior art〓 Conventionally, the cord collector used in a reeling machine is a disc-shaped one made of porcelain with a concave center. It is generally called a gathering button and has a thread threading hole in the center, and the size of the thread threading hole is selected as appropriate depending on the thickness of the thread to be reeled. For example, in the case of a raw silk fineness of 14d, which collects and reels 5-6 cocoon filaments, the thread diameter of the thread hole is 126 to 162 microns, and in the case of 21d, which collects cocoon silk of 7 to 8 cocoons, the diameter of the thread hole is 198 to 216 microns. microns, 253 to 337 microns for 42d.

As mentioned above, a cord collector with a predetermined thread hole diameter is used depending on the fineness of the yarn to be reeled, but after long-term use, the area around the thread hole becomes worn and the hole wall gets scratched. The rough surface comes into contact with the passing yarn, causing fluffing of the yarn, and furthermore, causing damage to the yarn such as torn yarn.

For this reason, cord collectors were considered consumables and were replaced in a timely manner, but since each cord collector required one, the number of cord collectors became enormous, which also caused economic problems.

〓Problems to be solved by the invention〓 In view of the above points, the present invention aims to improve the abrasion resistance of the thread passing hole of the cord collector and to obtain a cord collector that can be economically produced at low cost. The purpose is to

〓Means for solving the problem〓 The cord collector of the present invention is a wear-resistant cord collector having a support hole of a predetermined diameter in the support hole provided in the main body of the button, which is made of a metal or synthetic resin material and has a flat or arc shape. The button main body and the cord collecting member were fixed together by fitting or screwing together a cord collecting member made of a cemented carbide ceramic having a high temperature.

〓Example〓 An example of the cord collector 10 of the present invention will be described below with reference to the drawings.

A first embodiment is shown in FIGS. 1 to 3.

The button main body 1 is made of a resin material and has a circular planar shape, and both the upper and lower surfaces are arc-shaped, the radius of the upper arc-shaped surface is smaller than the radius of the lower arc-shaped surface, and the center part is The meat is thinner than the other parts.
The periphery of the button main body 1 is surrounded by a groove 3 that engages with a support member 2. A cord collection member support hole 4 is provided in the central portion, and a cord collection member 6 made of wear-resistant cemented carbide ceramics and having a thread passage hole 5 in the center is inserted and fixed into the hole 4. Examples of wear-resistant cemented carbide ceramics include tungsten,
Although the ceramic contains a carbide such as tantalum, it goes without saying that ceramics having other compositions may be used as long as they have a high degree of wear resistance.

The button main body 1 and the cord collecting member 6 may be fixed by using the button main body 1 having elasticity made of a resin material, and by using the elasticity of the button main body 1 to fix the string collecting member 6 in the string collecting member support hole 4. Alternatively, if the button does not have elasticity, a screw may be formed between the button main body 1 and the cord gathering member 6, and the two may be screwed together to fix the button.

The cord collection member 6 may be colored differently depending on the diameter of the thread passing hole 5 to prevent misuse among different types.

FIG. 4 shows a second embodiment.

In the second embodiment, the button main body 1A is a plate-shaped body having an appropriate planar shape, and an appropriate portion of its periphery is supported by a support member (not shown) by appropriate means.

The button main body 1A is preferably made of metal or synthetic resin material, and the means for supporting the cord gathering member 6 may be the same as in the first embodiment.

When using the cord collector 10, the support member 2
The button main body 1 is fixed to the thread collecting member 6, and the thread is passed through the thread passing hole 5, and the thread is wound up. Therefore, even during long-term contact with the thread, there is very little wear and the surface remains smooth, and the thread can be rolled up without damaging the surface.

〓Effects of the invention〓 The cord collector of the present invention supports a cord collection member made of a wear-resistant cemented carbide alloy having a thread passage hole in a cord collection member support hole provided in the plate-shaped button main body. Because of this, the thread collection member made of abrasion-resistant cemented carbide ceramics is in constant contact with the thread, which results in extremely little wear on the thread collection member and ensures that the peripheral surface of the thread threading hole remains smooth for a long time. It is possible to maintain the condition of the thread and prevent the occurrence of fuzzing or splitting of the thread.

In addition, since the wear-resistant cemented carbide ceramic stringing member with thread holes is integrally fixed to the button main body, the amount of expensive wear-resistant cemented carbide ceramics used is reduced compared to the button main body. The amount can be reduced compared to the case where it is used throughout, and it is economically advantageous as well as having a longer service life.
