本考案は、フイラメントや紡績糸の如き糸条を
巻き取るために用いられる糸条巻取コツトの改良
に関する。[Detailed Description of the Invention] (Technical Field of the Invention) The present invention relates to an improvement in a yarn winding tip used for winding yarn such as filament or spun yarn.
（考案の技術的背景）
この種の巻取コツトは、第５図に示すように、

に挟み込んで挟持させつつ巻回することにより糸
条が巻き付けられ、これにより糸条を連続的に巻
き取ることができる。(Technical background of the invention) This type of winding tip is as shown in Figure 5.
A cylindrical core metal 1 made of aluminum, Bakelite, etc., a rubber layer 2 provided with a uniform thickness on the core metal 1, and an annular slit 3 provided on one end side of the rubber layer 2. When used, the starting end of yarn such as spun yarn is slit 3.
The thread is wound by winding the thread while sandwiching and holding the thread between the threads, thereby making it possible to continuously wind the thread.
さて、かかる構造の巻取コツトは、従来、接着
剤の塗布されている芯金１上に未加硫ゴムを押出

により製造されている。 Conventionally, in a winding device having such a structure, unvulcanized rubber is directly provided on the core metal 1 coated with adhesive by extrusion or the like, and then this unvulcanized rubber is vulcanized to form a rubber layer. 2 and then annular cuts are made in the rubber layer 2 to form slits 3.

糸条の巻始端の挟持が不可能になつてしまう。よ
つて、従来の巻取コツトでは比較的太い糸条しか
挟持できない不具合があり、ごく特殊な用途でし
か使用できない問題がある。(Problems with Background Art) However, since the rubber layer 2 is vulcanized at a high temperature, it contracts at room temperature, causing distortion in the direction of the arrow as shown in FIG. 6A. That is, the linear expansion coefficients of the core metal 1 made of aluminum or Bakelite are 0.257×10 -4 and 0.3×10 -4 to 0.4×10 -4 respectively.
In contrast, that of rubber layer 2 is 1.5×10 -4
~3.0×10 −4 , so the contraction of the rubber layer 2 is about 4 to 10 times that of the core metal 1. Therefore, large distortion occurs in the rubber layer 2 at room temperature. Therefore, as shown in FIG. 6B, when an annular cut is made in the rubber layer 2 to provide a slit 3, shrinkage is suppressed because the inside of the rubber layer 2 is bonded to the core bar 1, and the shrinkage is suppressed. On the other hand, the surface side of the rubber layer 2 gradually contracts at room temperature due to its distortion. And like this, rubber layer 2
When only the surface side of the yarn gradually shrinks, the gap between the slits 3 also gradually increases, making it impossible for the slits 3 to hold the winding start end of the yarn. Therefore, the conventional winding method has the problem that it can only hold relatively thick yarns, and can only be used for very special purposes.

けることができる。 As shown in Fig. 1, the yarn winding device according to the present invention includes a cylindrical core bar 4 made of aluminum, and the core bar 4 has an outer diameter of 102 mm and a wall thickness of 4 mm. . A rubber layer 5 is provided on the circumferential surface of the core bar 4 except for one end thereof. This rubber layer 5 is made of acrylonitrile butadiene rubber, has a thickness of 4 mm, and is fixed onto the core bar 4 with epoxy resin. An annular slit forming member 6 is fitted onto the peripheral surface of one end side of the core bar 4 that does not have the rubber layer 5 . This slit forming member 6
As shown in FIG. 2, the annular body 6A on the inner peripheral side
and the rubber portion 6 formed on this annular body 6A.
It consists of B. The annular body 6A is made of aluminum and has a wall thickness of 1.5 mm. On the other hand, the rubber part 6
B consists of acrylonitrile butadiene rubber;
It has a wall thickness of 2.5mm. And the annular body 6A
A screw hole 7 is formed in the outer end surface of the metal core 4 and the end surface 4a of the core bar 4 on the one end side so as to span these. Therefore, by fitting the slit forming member 6 to one end of the core metal 4 and forming the screw hole 7 by aligning the member 6, the screw 8 is screwed into the screw hole 7. The slit forming member 6 can be attached to the core metal 4.

The pressing force against the end surface 5a is appropriately set by the amount of screw engagement. As a result, slits 3 having a predetermined interval are formed.
The end face of the slit forming member 6 and the end face 5 of the rubber layer 5
It can be formed between a.

きた。 The winding tip of the present invention is attached to the rotating shaft of the winding mechanism, and the winding start end of the 50 denier nylon filament is held between the slits 3 at 7000 to 8000 r.p.
The nylon filament was rotated at a high speed of m, thereby winding up the nylon filament. When this winding operation was repeated, it became impossible to hold the nylon filament. This is because the surface side of the rubber layer 5 gradually contracts as the temperature rises to room temperature, and the gap between the end surface 5a of the rubber layer 5 and the end surface of the slit forming member 6, ie, the gap between the slits 3, becomes larger. Therefore, the screw 8 was tightened and the end surface of the annular body 6A of the slit forming member 6 was further pressed against the opposing end surface 5a of the rubber layer 5, thereby adjusting (reducing) the gap between the slits 3. As a result, the winding start end of the nylon filament was again held between the slits 3 and the filament could be wound.

きるので経済的である。 By the way, if it becomes impossible to adjust the gap between the slits 3 even by tightening the screws 8, the slit forming member 6 may be replaced with another slit forming member 6 having a slightly larger width, for example. This is economical because the winding device can be used again by simply replacing a portion.

部材６と交換することができる。 Another embodiment of the invention is shown in FIG. That is, in this embodiment, the annular body 6A of the slit forming member 6 protrudes in the thickness direction and is attached to the core metal 4.
A protrusion 6a facing the end surface 4a is formed, and a screw 8 is passed through the protrusion 6a. The tip of the screw 8 is screwed into a screw hole 4b provided in the end surface 4a of the core metal 4. Therefore, the gap between the slits 3 can be adjusted by adjusting the tightening amount of the screws 8, and by removing the screws 8, the slit forming member 6 can be replaced with another slit forming member 6.

This annular body 6A is screwed into a thread groove on the circumferential surface of the core metal 4. On the other hand, the protrusion 6a of the annular body 6A has a long hole 6.
b is formed, and the screw 8 is screwed into the screw hole 4b of the core metal 4 through this elongated hole 6b, thereby preventing the annular body 6A from coming off from the core metal 4. In this embodiment, the interval between the slits 3 can be adjusted by adjusting the amount of screwing of the annular body 6A into the mandrel 4.

提供することが可能である。(Effects of the invention) According to the invention, a rubber layer is provided on the circumferential surface of the cored bar except for one end thereof, and an annular slit forming member having a rubber portion on the surface side is attached and detached from the circumferential surface of one end of the cored bar. The slit gap can be adjusted arbitrarily by fitting the annular slit forming member to the end surface of the rubber layer using a pressing means, and since the annular slit forming member is a separate member, can only be replaced. Therefore, it is desirable to provide an economical winding tip that can reliably hold the winding start end of the yarn by the slit even after repeated use and can easily wind even a thin yarn. It is possible.
