本発明では、回転数Rを高くして紐状物の円弧の半径を小さくし、回転数Rを低くして紐状物11の円弧の半径を大きくすることにより、紐状物11の配置軌跡を、回転軸から偏芯した円形状軌跡にすることができる。例えば、図3に示すような、円形状で、その円形内に芯棒15が配置された配置軌跡を形成できる。 As shown in FIG. 4, while supplying the
In the present invention, the rotation path R is increased to reduce the arc radius of the string-like object, and the rotation speed R is decreased to increase the arc radius of the string-
「収納容器の容器半径」または「収納容器の半径」とは、収納容器12の中心部から収納容器の内壁面までの距離を意味する。
収納容器12が1回転する際に形成される紐状物11の配置軌跡の一部が、芯棒外壁からの距離d2が、収納容器の半径と芯棒半径の差d1の30%以内であり、かつ、収納容器内壁からの距離d3が、収納容器の半径と芯棒半径の差d1の30%以内であるように、回転数R(回転/分)の変動パターンを設定することにより、収納容器12に紐状物をより均一に収納できる。
なお、図3では、d2及びd3が、それぞれ、d1の0~30%の範囲を通過する場合を示している。
紐状物11の配置軌跡の一部が、中央領域12aと外周領域12bとを通過すれば、収納容器12の全体に、さらにより均一に紐状物11を収納できる。 Moreover, as a preferable aspect of the fluctuation pattern of the rotation speed R (rotation / min) of the

A part of the arrangement trajectory of the string-
FIG. 3 shows a case where d2 and d3 pass through a range of 0 to 30% of d1.
If a part of the arrangement trajectory of the string-
図3に示す配置軌跡にするための回転数Rの変動パターンは、以下の方法で設定することができる。
まず、回転数Rの変動パターンを設定するにあたって、回転数Rの変動パターンの平均回転数Raを設定する。
そのために、収納容器12の1回転あたりの紐状物11の収納長さを求める。図3に示す配置軌跡では、1つの円形における紐状物11の長さが、収納容器12の1回転あたりの紐状物11の収納長さに相当する。
そして、模擬的に、得ようとする紐状物11の円形を1つ形成し、その円周長さを測定し、その測定値より、収納容器12の1回転あたりの紐状物11の収納長さLr(m/回転)を求める。
また、この収納長さLr(m/回転)、紐状物11の供給速度v(m/分)より平均回転数Ra(回転/分)を求める。具体的には、Ra =v/Lrの式より求める。 (Setting of fluctuation pattern of rotation speed R)
The fluctuation pattern of the rotational speed R for making the arrangement locus shown in FIG. 3 can be set by the following method.
First, when setting the variation pattern of the rotation speed R, to set the average rotational speed R a pattern of variation of the rotational speed R.
For this purpose, the storage length of the string-
Then, as a simulation, one circular shape of the string-
Further, an average rotational speed R a (rotation / min) is obtained from the storage length L r (m / rotation) and the supply speed v (m / min) of the
そのためには、上記のように決定した平均回転数Raから容器1回転あたりの時間(回転周期Ta)を、Ta=60/Raの式から求める。
また、収納容器12の1回転で形成される紐状物11の円形状の配置軌跡と、次の収納容器12の1回転で形成される円形状の配置軌跡とのずれ角度を決めておく。このときには、暫定的に周期Tを決定するために、図3に示すように形成された紐状物11の配置形状から見積もって、暫定的にずれ角度を決めればよい。ずれ角度は、収納効率の観点からは、できるだけ小さい角度とすることが好ましいが、ずれ角度を小さくし過ぎると、紐状物11の積み重なり高さが大きくなり、かえって収納効率を低下させるおそれがある。そのため、収納状態を見ながら、ずれ角度を適宜修正することが好ましい。
ずれ角度△θ(°)を生じさせるための時間△T(秒)は、△T=Ta・△θ/360(°)の式より求められる。
そして、1周期Tを、Ta+△Tとする。したがって、1周期Tは、Ta+Ta・△θ/360で求めることができる。
なお、ΔT(秒)が0秒であると、T=Taとなり、回転数Rの周期的変動の1周期における収納容器12の回転角度が360°となるため、紐状物11の円形状の配置軌跡が1周期T毎にずれなくなる。この場合は、図3に示すような、円形が少しずつずれるような配置軌跡にはならない。したがって、△Tが0であることはない。 Next, one period T (see FIG. 4) of the periodic fluctuation of the rotational speed R is determined.
For that purpose, the time per rotation of the container (rotation cycle T a ) is determined from the average rotation number R a determined as described above from the equation of T a = 60 / R a .
Further, a deviation angle between the circular arrangement locus of the string-
The time ΔT (second) for generating the deviation angle Δθ (°) is obtained from the equation: ΔT = Ta · Δθ / 360 (°).
One cycle T is defined as T a + ΔT. Therefore, one period T can be obtained by T a + T a · Δθ / 360.
If ΔT (seconds) is 0 seconds, T = Ta , and the rotation angle of the
回転数Rの変動幅が大きくなるほど、紐状物11の軌跡は収納容器12の回転軸から大きく偏心したものとなり、回転数Rの変動幅が小さいほど、偏心状態ではなくなり、変動幅が0であると、紐状物11の軌跡は回転軸Cを中心としたものとなる。
その変動幅は、紐状物11の柔軟性や供給速度にも依存するため、目的とする配置軌跡が同じであっても、一義的には決定できず、紐状物11の柔軟性や供給速度に応じて適宜選択する必要がある。
そのため、まず、暫定的に回転数Rの変動幅を設定し、その回転数Rの変動パターン(平均回転数はRa、1周期はTとする。)における紐状物11の軌跡を確認する。得られた軌跡が回転軸Cの中心に近くにあり、回転軸Cから遠ざけたい場合には回転数Rの変動幅を大きくし、得られた軌跡が回転軸の中心から遠くにあり、回転軸Cに近づけたい場合には回転数Rの変動幅を小さくする。その後、再び紐状物11の軌跡を確認し、所望の軌跡と異なる場合には変動幅を調整する。このような変動幅の調整を繰り返すことにより、変動幅を決定する。 Further, the fluctuation range of the rotational speed R is determined.
The larger the fluctuation range of the rotation speed R, the more the locus of the string-
Since the fluctuation range depends on the flexibility and supply speed of the string-
Therefore, first, the fluctuation range of the rotational speed R is provisionally set, and the locus of the string-
以上のように、平均回転数Ra、1周期T、回転数Rの変動幅を決定して、回転数Rの変動パターンを設定する。 Further, if necessary, one cycle T may be further finely adjusted from the viewpoint of storage efficiency. That is, by making a fine correction to reduce ΔT (seconds), the shift angle Δθ (°) can be reduced, and the storage efficiency can be further increased.
As described above, the fluctuation range of the rotational speed R is determined by determining the average rotational speed R a , the period T, and the fluctuation range of the rotational speed R.
0.64Ra < Rw < 2Ra (4)
の条件を満たすことが好ましい。
変動幅Rwが0.64Raより小さいと、紐状物のループが偏芯せず、芯棒外壁近傍あるいは容器内壁近傍に配置できなくなる懸念があり、また、2Raよりも大きくなると、紐状物のループが収納パッケージ内にきれいに収まらなくなる懸念が生じる。 When the fluctuation range of the rotational speed R is R w (rotations / minute), R w is expressed by the following formula (4):
0.64R a <R w <2R a (4)
It is preferable to satisfy the following condition.

収納する紐状物として、ポリエステル原糸(南亜製、「84dtex-72fil」)を5本束ねた状態で丸編された、外径約2.5mm、内径約1.8mmの編紐を使用した。この編紐を、100m/時間の速度で連続的に製紐しながら容器に供給し、収納することとした。
収納装置としては、図1に示す構成のものを用いた。収納容器12としては、内径約450mm、高さ820mmの内容積の中心部に、外径約130mmの芯棒15を取り付けた構造の円筒形のペーパードラムを使用した。

As a string to be stored, a knitted string having an outer diameter of about 2.5 mm and an inner diameter of about 1.8 mm, which is circularly knitted in a state where five polyester yarns (made by Nanya, "84 dtex-72fil") are bundled, is used. did. This knitted string was supplied to the container and stored while continuously stringing at a speed of 100 m / hour.
As the storage device, the one having the configuration shown in FIG. 1 was used. As the
The rotary table 13 used was a structure that was rotated by a brushless DC motor (manufactured by Oriental Co.) that can be controlled within a range of 0.4 to 20 rotations / minute. The rotation speed R is changed by a system in which a fluctuation pattern program is input in the sequencer in advance, and at the same time the start button is pressed, a rotation speed command is output from the sequencer to the motor driver according to the fluctuation pattern of the rotation speed R. .
As the
上述の収納装置10を用い、収納容器12が2回転する際に形成される編紐の配置軌跡に、図3に示すように、編紐が2回交差する箇所が生じるように、かつ1周期Tで形成される編紐の配置軌跡が円形状でその円形が容器回転方向と逆方向にずれるように、周期Tおよび回転数Rを設定した。具体的には、図11に示すステップ状の回転数Rの変動パターン(1周期T:34秒、平均回転数Ra:1.75回転/分)を設定した。ここで、筒状容器の内壁面側の周長Lは0.45m×π≒1.41mであり、編紐の供給速度vの100m/時間を1分あたりに換算すると1.67m/分となる。したがって、v/L≒1.18/分となり、平均回転数Ra=1.75>v/Lとなる。
このような回転数Rの変動パターンで、収納容器12を回転させながら編紐(紐状物)11を収納容器12内に収納した。その結果、図3に示すような配置軌跡で、約100時間の収納時間で約10000mの量の編紐を収納できた。また、本例では、収納容器12が1回転する際に形成される紐状物11の配置軌跡が中央領域と外周領域とを通過し、収納容器12が2回転する際に形成される紐状物11の配置軌跡が収納容器の回転軸Cを囲む軌跡になっている。
この収納形態は崩れにくく、また、静止状態の収納容器12から編紐を10m/分の速度で引き出したところ、絡みの発生はなく、安定した状態で引き出すことができた。 <Example 1>
As shown in FIG. 3, the knitting string is arranged twice when the
The braided string (string-like material) 11 was stored in the
This storage form was not easily collapsed, and when the knitted string was pulled out from the
上述の収納装置10を用い、収納容器12が2回転する際に形成される編紐の配置軌跡が、編紐が交差する箇所が生じないように、かつ1周期Tで形成される編紐の配置軌跡が渦巻き状になるように、周期Tおよび回転数Rを設定した。具体的には、図12に示すステップ状の回転数Rの変動パターン(1周期T:52分、平均回転数Ra:2.7回転/分)を設定した。ここで、筒状容器の内壁面側の周長Lは0.45m×π≒1.41mであり、編紐の供給速度vの100m/時間を1分あたりに換算すると、1.67m/となる。したがって、v/L≒1.18/分となり、平均回転数Ra=2.7>v/Lとなる。
このような回転数Rの変動パターンで、収納容器12を回転させながら編紐(紐状物)11を収納容器12内に収納した。その結果、図13に示すように、芯棒15を軸とした渦巻き状に編紐を配置することができた。また、約100時間の収納時間で約10000mの量の編紐を収納できた。
この収納では、収納容器12の内壁面付近あるいは芯棒15付近にて部分的に隙間が形成され、その部分に編紐が落ち込んでいる収納状態になっていた。そのため、静止状態の収納容器から編紐を10m/分の速度で引き出したところ、引っ掛かって円滑に編紐を引き出せなくなることがあった。また、渦巻き状の配置では、引き出される際の撚りが大きくなり、捩れた状態で編紐が引き出されるため、途中のガイドから外れそうになったり、引っ掛かりそうになったりする状況が見られた。 <Comparative Example 1>
