Description

本発明は、各糸の撚り長さを均一にするための引き揃え装置及びこれを備えた撚糸機に関する。   The present invention relates to an aligning device for making the twist length of each yarn uniform, and a twisting machine equipped with the same.

撚糸機は、二つの給糸パッケージからの各糸を撚り合わせて一本の撚糸を製造する(特許文献1参照)。撚糸は、タイヤコードやベルト芯体等に用いられる。給糸パッケージは、機台の上部と下部に設けられている。上下の給糸パッケージから繰り出された各糸は、撚糸装置で撚り合わされて一本の撚糸になる。下側の給糸パッケージは撚糸装置の内部に静止状態で支持され、この給糸パッケージから第一糸が繰り出される。上側の給糸パッケージから繰り出される第二糸は、撚糸装置に案内され撚糸装置の撚糸回転子により放射状に回転する。そして、各糸が互いに撚り合わされて撚糸となる。撚糸は機台中央の巻取りパッケージに巻き取られる。   The twisting machine twists each yarn from two yarn supply packages to produce one twisted yarn (see Patent Document 1). Twisted yarn is used for tire cords, belt cores, and the like. Yarn supply packages are provided at the upper and lower parts of the machine base. The yarns fed from the upper and lower yarn supply packages are twisted together by a twisting device to form one twisted yarn. The lower yarn supplying package is supported in a stationary state inside the twisting device, and the first yarn is fed out from the yarn supplying package. The second yarn fed out from the upper yarn supplying package is guided to the twisting device and rotated radially by the twisting rotor of the twisting device. And each thread | yarn is mutually twisted and turns into a twisted thread | yarn. The twisted yarn is wound on a winding package in the center of the machine base.

このような撚糸機は、巻取りパッケージの巻取り手前に引き揃え装置(長さ調整器)を備えている(特許文献1の図1、符号7参照)。この引き揃え装置によって、各給糸パッケージから繰り出される各糸を均一な長さに調整して撚り合わすことができる。しかし、従来の引き揃え装置は、各糸と糸を掛けて揃えるためのローラとの間でスリップが生じたりして、各糸の長さが不均一になる場合がある。不均一な糸によって製造された撚糸は、強度不足等、品質上問題がある。
特開2005−48311号公報
Such a twisting machine includes an aligning device (length adjuster) before winding of the winding package (see FIG. 1 of Patent Document 1 and reference numeral 7). By this aligning device, the yarns fed out from the yarn supply packages can be adjusted to a uniform length and twisted together. However, in the conventional aligning device, there is a case where slip occurs between the yarns and the rollers for aligning the yarns to make the lengths of the yarns nonuniform. Twisted yarns produced with non-uniform yarns have quality problems such as insufficient strength.
JP-A-2005-48311

そこで本発明が解決しようとする課題は、各糸を均一に引き揃え高品質な撚糸を製造する引き揃え装置及びこれを備えた撚糸機を提供することにある。   Therefore, the problem to be solved by the present invention is to provide an aligning apparatus for uniformly aligning each yarn and producing a high-quality twisted yarn and a twisting machine equipped with the aligning device.

前記の課題を解決するための手段として、本発明に係る引き揃え装置は、二本の糸を撚り合わせて撚糸を製造する撚糸機に備えられ、各糸の撚り長さを均一にする引き揃え装置において、軸芯に対して回転可能な本体と、この本体に設けられ軸芯に対して略直交する軸方向の少なくとも二つのローラとを備えており、各糸を各ローラに架け渡してなる。   As a means for solving the above-mentioned problems, the aligning device according to the present invention is provided in a twisting machine for producing a twisted yarn by twisting two yarns, and aligning the twisting lengths of the respective yarns uniformly. The apparatus includes a main body rotatable with respect to an axis and at least two rollers provided on the main body in an axial direction substantially orthogonal to the axis, and each yarn is stretched over each roller. .

Cylindrical shaft portions 3 b and 4 b of the rollers 3 and 4 are fixed to the main body 2. The rollers 3 and 4 are rotatable around the shaft portions 3b and 4b via bearings 3c and 4c. The bearings 3c and 4c are provided in the vicinity of the shaft core C, thereby reducing the influence of centrifugal force due to the rotation of the main body 2 described later, and problems such as shortening the life due to grease scattering are improved. The groove portions 3 a of the groove roller 3 are provided at five locations at substantially equal intervals in the axial direction of the roller 3, and the groove portions 3 a at the central portion are disposed on the shaft core C.

図3に示すように、引き揃え装置1は、本体2の上部にハウジング6を備えている。ハウジング6は、機台11にボルト等の連結部材(図示略)を介して連結固定される(図1)。ハウジング6は、中心に回転軸7を備えている。回転軸7は、ハウジング6に設けられた一対の軸受け6a,6aを介して軸芯Cを中心に回転自在に構成されている。ハウジング6は、軸受け6aにグリスを注入するためのグリス導入路6bを備えている。グリス導入路6bには逆止弁等を有するグリスニップル(図示略)が設けられる。   As shown in FIG. 3, the aligning device 1 includes a housing 6 at the top of the main body 2. The housing 6 is connected and fixed to the machine base 11 via a connecting member (not shown) such as a bolt (FIG. 1). The housing 6 has a rotation shaft 7 at the center. The rotating shaft 7 is configured to be rotatable about an axis C through a pair of bearings 6 a and 6 a provided in the housing 6. The housing 6 includes a grease introduction path 6b for injecting grease into the bearing 6a. The grease introduction path 6b is provided with a grease nipple (not shown) having a check valve or the like.

回転軸7の下端と本体2の上端は、連結固定されている。従って、本体2は、回転軸7の回転によって、軸芯Cを中心に回転可能に構成されている。本体2は、上部及び下部に、上下方向に貫通する一対の糸挿通孔2b,2cを備えている。各糸挿通孔2b、2cは、軸芯C上に配設されている。回転軸7は、中心に上下方向に貫通する糸挿通孔7aを備えている。この糸挿通孔7aも軸芯C上に配設されている。従って、本体2上部の糸挿通孔2cと回転軸7の糸挿通孔7aは連通している。   The lower end of the rotating shaft 7 and the upper end of the main body 2 are connected and fixed. Therefore, the main body 2 is configured to be rotatable about the axis C by the rotation of the rotary shaft 7. The main body 2 includes a pair of thread insertion holes 2b and 2c penetrating in the vertical direction at the upper and lower portions. Each thread insertion hole 2b, 2c is disposed on the shaft core C. The rotary shaft 7 includes a thread insertion hole 7a penetrating in the vertical direction at the center. The thread insertion hole 7a is also disposed on the shaft core C. Therefore, the thread insertion hole 2c in the upper part of the main body 2 and the thread insertion hole 7a of the rotary shaft 7 communicate with each other.

引き揃え装置1は、本体2の略中央に円盤状の糸角度調整部5を備えている。図2の如く、糸角度調整部5は、上下方向に貫通する一対の糸挿通孔5a,5bを備えている。更に、糸角度調整部5は、各糸挿通孔5a,5bの間に、径方向に切り欠かれたスリット5cを備えている。後述するように各糸Y1及びY2を各ローラ3,4に架け渡す際、糸角度調整部5が邪魔になるので、各糸Y1,Y2をこのスリット5cに通過させて架け渡し易くなっている。糸挿通孔5a,5b及びスリット5cは、引き揃え装置1のバランスをとる等のために、図2の奥側にも設けられている(図示略)。   The aligning device 1 includes a disk-shaped thread angle adjusting unit 5 in the approximate center of the main body 2. As shown in FIG. 2, the yarn angle adjusting unit 5 includes a pair of yarn insertion holes 5a and 5b penetrating in the vertical direction. Furthermore, the yarn angle adjusting unit 5 includes a slit 5c cut out in the radial direction between the yarn insertion holes 5a and 5b.

上記のように、各糸Y1及びY2は、糸角度調整部5に設けられた各糸挿通孔5a及び5bに案内されて溝ローラ3に掛けられる。従って、各糸Y1,Y2の各ローラ3,4に対する巻き付け角度αは一定になると共に大きくすることができる。更に、各ローラ3,4の径も大きくできる。これらにより、各糸Y1,Y2の各ローラ3,4に対する巻き付け角度αの一定化及び巻き付け量が多くなり、スリップを少なくして均一に引き揃えることができる。更に、撚糸装置12の停止時や各糸Y1,Y2にテンション差がある場合でも、均一に引き揃えることができる。   As described above, the yarns Y1 and Y2 are guided by the yarn insertion holes 5a and 5b provided in the yarn angle adjusting unit 5 and are hung on the groove roller 3. Therefore, the winding angle α of the yarns Y1 and Y2 around the rollers 3 and 4 can be made constant and large. Furthermore, the diameter of each roller 3 and 4 can also be enlarged. As a result, the winding angle α of the yarns Y1 and Y2 around the rollers 3 and 4 is made constant and the amount of winding is increased, so that slip can be reduced and the yarns can be uniformly aligned. Further, even when the twisting device 12 is stopped or when there is a tension difference between the yarns Y1 and Y2, the yarns can be uniformly aligned.

本実施形態では、上下二つのローラ3,4であるが三つ以上でもよい。また、上部に平ローラ4を、下部に溝ローラ3を配設してもよい。各ローラ3,4共に、溝ローラ又は平ローラでもよい。各糸Y1,Y2を所定の角度でローラ3へ掛ける手段として、本形態では円盤状の糸角度調整部5等であるが、各糸Y1,Y2を掛止するフック状のもので構成してもよい。   In this embodiment, the upper and lower rollers 3 and 4 are provided, but three or more may be used. Further, the flat roller 4 may be disposed at the upper portion and the groove roller 3 may be disposed at the lower portion. Each of the rollers 3 and 4 may be a groove roller or a flat roller. As a means for hooking each yarn Y1, Y2 to the roller 3 at a predetermined angle, in this embodiment, it is a disk-like yarn angle adjusting section 5 or the like, but it is configured by a hook-like one that hooks each yarn Y1, Y2. Also good.
