Description

本発明は繊維分配装置及び繊維分配方法に関する。   The present invention relates to a fiber distribution device and a fiber distribution method.

不織布は構成繊維、繊維ウエブの形成方法、あるいは繊維ウエブの結合方法を適宜組み合わせることにより、各種機能を付与できるため、各種用途に適用されている。   Nonwoven fabrics can be imparted with various functions by appropriately combining constituent fibers, fiber web forming methods, or fiber web bonding methods, and are therefore applied to various applications.

このような不織布のもととなる繊維ウエブは、カード機などの繊維開繊装置へ繊維を供給し、開繊することによって形成することができるが、不織布の生産性を高めるためには、そのもとである繊維ウエブの生産性を高める必要があるため、繊維ウエブの幅を広くすることが考えられる。このように繊維ウエブの幅を広くするには、繊維開繊装置を繊維ウエブの幅に見合った開繊能力とする必要があるが、それには限度があった。そこで、繊維開繊装置を複数台並列に設置することにより繊維ウエブの幅を広くすることが考えられた。   The fiber web that is the basis of such a nonwoven fabric can be formed by supplying fibers to a fiber opening device such as a card machine and opening the fiber. In order to increase the productivity of the nonwoven fabric, Since it is necessary to increase the productivity of the original fiber web, it is conceivable to increase the width of the fiber web. In order to widen the width of the fiber web in this way, the fiber opening device needs to have a fiber opening capacity corresponding to the width of the fiber web, but this has a limit. Therefore, it has been considered to increase the width of the fiber web by installing a plurality of fiber opening devices in parallel.

例えば、本願出願人は繊維ウエブの幅を広くできる繊維ウエブ製造装置として、「繊維を噴出できるノズルと、前記ノズルへの圧縮気体導入手段と、前記ノズルの噴出口の前方に位置し、前記ノズルから噴出した繊維と衝突して繊維を分散できる衝突部材と、前記衝突部材を囲むとともに、前記衝突部材との衝突によって分散する繊維を導く囲い部材とを備えた繊維分散ユニットを複数備えており、前記複数の繊維分散ユニットの囲い部材により導かれる繊維を捕集する捕集部材を備えていることを特徴とする、繊維ウエブ製造装置。」を提案した（特許文献１）。この繊維ウエブ製造装置は繊維分散ユニットを複数備えているため、繊維ウエブの幅を広くすることが可能であった。   For example, the applicant of the present application is a fiber web manufacturing apparatus that can widen the width of the fiber web, as follows: “a nozzle capable of ejecting fibers, a compressed gas introduction means to the nozzle, and a nozzle outlet located in front of the nozzle; A plurality of fiber dispersion units including a collision member that can collide with the fibers ejected from the fiber and disperse the fiber, and a surrounding member that surrounds the collision member and guides the fiber dispersed by the collision with the collision member; A fiber web manufacturing apparatus comprising a collecting member that collects fibers guided by the enclosure members of the plurality of fiber dispersion units is proposed (Patent Document 1). Since this fiber web manufacturing apparatus includes a plurality of fiber dispersion units, the width of the fiber web can be increased.

このような繊維ウエブ製造装置を使用して繊維ウエブを製造したところ、繊維の分配が不均一で、個々の繊維分散ユニットへ供給する繊維量が不均一であることに起因して、繊維ウエブの幅方向における繊維量が不均一である場合が発生した。このような現象は上述のような繊維ウエブ製造装置に限らず、従来のカード機等の繊維開繊装置を使用した場合にも起りうる現象であった。   When a fiber web is manufactured using such a fiber web manufacturing apparatus, the fiber distribution is uneven and the amount of fibers supplied to the individual fiber dispersion units is uneven.

As a method of distributing the fiber supplied from the weighing machine, the T-type pipe Pt as schematically shown in FIG. 6 and the model shown in FIG. Since the Y-shaped pipe Py that shows a specific cross section was used, the fibers supplied from the D direction were transferred to distribute the fibers in the D 1 and D 2 directions, particularly in the case of the latter Y-shaped pipe Py.

本発明の繊維分配装置について、図面をもとに説明する。   The fiber distribution device of the present invention will be described with reference to the drawings.

図１は繊維ウエブ製造装置の模式的概念図である。この繊維ウエブ製造装置においては、繊維を計量し、所定量の繊維を連続的に供給できる計量機１、計量機１から供給された繊維を２つに分配し、繊維を供給できる第１繊維分配装置２、第１繊維分配装置２から供給された繊維を４つに分配し、繊維を供給できる第２繊維分配装置３ａ、３ｂ、第２繊維分配装置３ａ、３ｂから供給された繊維を開繊し、繊維ウエブとする繊維開繊装置４ａ１〜４ａ４、４ｂ１〜４ｂ４、及び繊維開繊装置４ａ１〜４ａ４、４ｂ１〜４ｂ４により形成されたそれぞれの繊維ウエブＦを受け取る捕集体５、とから構成されている。本発明の繊維分配装置は上述のような第１繊維分配装置２及び／又は第２繊維分配装置３ａ、３ｂとして使用できる。なお、繊維分配装置は２つ以上に繊維を分配できれば良く、分配数は特に限定するものではない。しかしながら、繊維を２〜１６に分配できるのが好ましい。 FIG. 1 is a schematic conceptual view of a fiber web manufacturing apparatus. In this fiber web manufacturing apparatus, the fiber is weighed, the weighing machine 1 capable of continuously supplying a predetermined amount of fiber, the fiber supplied from the weighing machine 1 is divided into two, and the first fiber distribution capable of supplying the fiber. The fibers supplied from the device 2 and the first fiber distribution device 2 are distributed into four, and the fibers supplied from the second fiber distribution devices 3a and 3b and the second fiber distribution devices 3a and 3b that can supply the fibers are opened. The fiber opening devices 4a 1 to 4a 4 , 4b 1 to 4b 4 , and the fiber opening devices 4a 1 to 4a 4 and 4b 1 to 4b 4 that receive the respective fiber webs F to be used as the fiber webs are received. It is comprised from the collection 5. The fiber distribution device of the present invention can be used as the first fiber distribution device 2 and / or the second fiber distribution devices 3a and 3b as described above. In addition, the fiber distribution apparatus should just distribute a fiber to two or more, and the number of distribution is not specifically limited. However, it is preferred that the fibers can be distributed between 2 and 16.

本発明の繊維分配装置について、その模式的斜視図である図２、及び図２のＳ−Ｓ’線で切断した模式的断面図である図３をもとに説明する。   The fiber distribution device of the present invention will be described with reference to FIG. 2 which is a schematic perspective view thereof and FIG. 3 which is a schematic cross-sectional view taken along the line S-S ′ of FIG.

本発明の繊維分配装置２０は、内部が円柱状中空の筐体２１と、この筐体２１内に回転可能な回転体２２（図３参照）を備えている。この筐体２１は筐体２１の内部へ繊維を供給できる繊維供給口２１ｉを筐体２１の上壁面の中央部に備えているとともに、筐体２１の側壁面（後述の羽根２２ｆ１〜２２ｆ４の高さの範囲内）に、内部の繊維を排出できる４つの繊維排出口２１ｏ１〜２１ｏ４を備えている。また、筐体２１内の回転体２２は４枚の羽根２２ｆ１〜２２ｆ４と羽根２２ｆ１〜２２ｆ４を担持する円盤状のベース基材２２ｂとからなり、各羽根２２ｆ１〜２２ｆ４はベース基材２２ｂの中心を回転軸側の端部Ｅとし、この回転軸側端部Ｅから筐体２１の内部壁面Ｗ方向に直線状に傾斜した側壁Ｃｃをもつ平板からなり、羽根２２ｆ１〜２２ｆ４はベース基材２２ｂの中心に対して放射状に等間隔で配置されている。なお、各羽根２２ｆ１〜２２ｆ４の側壁Ｃｃとベース基材２２ｂとのなす角度（図３におけるα）は、特に限定するものではないが、繊維が堆積しにくいように、６０°以下であるのが好ましい。また、この回転体２２はモーター等の駆動力（図示しない）によって回転可能な状態にある。 The fiber distribution device 20 of the present invention includes a casing 21 having a cylindrical hollow inside, and a rotating body 22 (see FIG. 3) that can rotate in the casing 21. With the housing 21 is provided with a fiber supply port 21i capable of supplying fiber to the housing 21 in a central portion of the upper wall surface of the housing 21, the blade 22f 1 ~22f 4 side wall surface (below the housing 21 the in the high range of the) has four fiber outlet 21o 1 ~21o 4 can be discharged to the interior of the fibers. Further, the rotary member 22 in the casing 21 consists of a disk-shaped base member 22b carrying the four blades 22f 1 ~22f 4 and the blade 22f 1 ~22f 4, each vane 22f 1 ~22f 4 base the center of the substrate 22b and the end portion E of the rotation shaft side and a flat plate having a sidewall Cc inclined linearly inside wall W direction of the housing 21 from the rotating shaft side end portion E, the blade 22f 1 ~22f 4 are arranged radially at equal intervals with respect to the center of the base substrate 22b. The angle (α in FIG. 3) formed by the side wall Cc of each of the blades 22f 1 to 22f 4 and the base substrate 22b is not particularly limited, but is 60 ° or less so that fibers are not easily deposited. Is preferred. The rotating body 22 is in a state of being rotatable by a driving force (not shown) such as a motor.

そのため、図２及び図３に示す繊維分配装置２０の繊維供給口２１ｉに計量機１等から繊維を供給すると、繊維は筐体２１内の回転体２２の回転による遠心力の作用を均等に受け、４つある繊維排出口２１ｏ１〜２１ｏ４から均等量の繊維が排出される。遠心力によって、繊維は筐体２１の内部壁面Ｗ方向へ移送されるが、回転体２２を構成する羽根２２ｆ１〜２２ｆ４の側壁Ｃｃは傾斜しているため、羽根２２ｆ１〜２２ｆ４に繊維が堆積することもない。したがって、堆積した繊維が一度に脱落して繊維量が不均一になることもない。 Therefore, when fibers are supplied from the weighing machine 1 or the like to the fiber supply port 21i of the fiber distribution device 20 shown in FIGS. 2 and 3, the fibers are equally subjected to the centrifugal force due to the rotation of the rotating body 22 in the housing 21. evenly amount of fibers are discharged from the four certain fiber outlet 21o 1 ~21o 4. The fibers are transferred in the direction of the inner wall surface W of the casing 21 by centrifugal force, but the side walls Cc of the blades 22f 1 to 22f 4 constituting the rotating body 22 are inclined, and therefore the fibers are transferred to the blades 22f 1 to 22f 4 . Does not accumulate. Therefore, the accumulated fibers are not dropped at a time and the amount of fibers is not uniform.

上記の繊維分配装置２０においては、筐体２１の内部が円柱状中空であるが、円柱状中空である必要はない。しかしながら、回転体２２が回転するため、円柱状中空であるのが好ましい。また、繊維供給口２１ｉを筐体２１の上壁面中央部に備えているが、中央部である必要はない。羽根２２ｆ１〜２２ｆ４の内部壁面Ｗ側側壁Ｃｗは筐体２１の内部壁面Ｗと接した状態にあるが、接している必要はない。更に、繊維排出口２１ｏ１〜２１ｏ４を羽根２２ｆ１〜２２ｆ４の高さの範囲内の側壁面に備えているが、回転体２２の遠心力を利用できるように、繊維供給方向Ｄと交差する方向に位置していれば良く、例えば、羽根２２ｆ１〜２２ｆ４の高さよりも高い場所に位置していても良い。なお、羽根の数は特に限定するものではない。 In the fiber distribution device 20 described above, the inside of the housing 21 is cylindrical hollow, but it is not necessary to be cylindrical hollow. However, since the rotating body 22 rotates, it is preferably a cylindrical hollow. Moreover, although the fiber supply port 21i is provided in the center part of the upper wall surface of the housing | casing 21, it does not need to be a center part. Although the inner wall surface W-side side wall Cw of the blades 22f 1 to 22f 4 is in contact with the inner wall surface W of the housing 21, it is not necessary to be in contact therewith. Furthermore, the fiber discharge ports 21o 1 to 21o 4 are provided on the side wall surface within the height range of the blades 22f 1 to 22f 4 , but intersect with the fiber supply direction D so that the centrifugal force of the rotating body 22 can be used. it is sufficient that located in the direction of, for example, may be located higher place than the height of the blade 22f 1 ~22f 4. The number of blades is not particularly limited.

本発明の繊維分配装置においては、回転体の遠心力を利用して繊維を分配しているため、遠心力の作用を受けやすく、しかも回転体の羽根に堆積しにくい、繊維径が４μｍ以下で繊維長が３ｍｍ以下の極細短繊維を含む繊維を効率的に分配することができる。特に、海島型繊維から海成分を除去して形成した島成分からなる極細短繊維は、製造上、極細短繊維が集合した束状の状態にある場合があるが、このような極細短繊維であっても、回転体の遠心力によって個々の極細短繊維に解きほぐしながら、均等に分配することができる。なお、本発明の繊維分配装置においては、回転体を使用しているため、繊維が回転体に堆積しにくいように、供給する繊維はいずれも巻縮をもたない繊維、つまり、チョップドファイバーであるのが好ましい。更に、本発明の繊維分散装置においては、液体中に分散した繊維を分配しても良いが、気体中に分散した繊維の方が遠心力を作用させて、均一に分配することができる。   In the fiber distribution device of the present invention, since the fiber is distributed using the centrifugal force of the rotating body, the fiber diameter is 4 μm or less, which is easily affected by the centrifugal force and is difficult to deposit on the blades of the rotating body. A fiber including an ultrafine short fiber having a fiber length of 3 mm or less can be efficiently distributed. In particular, an ultrafine short fiber made of island components formed by removing sea components from sea-island type fibers may be in a bundled state in which ultrafine short fibers are aggregated in production. Even in such a case, it is possible to distribute evenly while unraveling the individual ultrafine short fibers by the centrifugal force of the rotating body. In the fiber distribution device of the present invention, since the rotating body is used, the fibers to be supplied are all fibers that are not wound, that is, chopped fibers so that the fibers are not easily deposited on the rotating body. Preferably there is. Furthermore, in the fiber dispersion device of the present invention, fibers dispersed in a liquid may be distributed. However, fibers dispersed in a gas can be uniformly distributed by applying centrifugal force.

本発明の繊維分配装置における別の回転体について、図２のＳ−Ｓ’線で切断した模式的断面図と同様の模式的断面図である図４及び図５について説明する。   FIG. 4 and FIG. 5, which are schematic cross-sectional views similar to the schematic cross-sectional view taken along the line S-S ′ of FIG. 2, will be described for another rotating body in the fiber distribution device of the present invention.

図４の回転体２２は４枚の羽根２２ｆ１〜２２ｆ４（図面上２枚のみ）と羽根２２ｆ１〜２２ｆ４を担持するベース基材２２ｂとからなり、羽根２２ｆ１〜２２ｆ４はベース基材２２ｂの中心を回転軸側の端部Ｅとし、この回転軸側端部Ｅから筐体２１の内部壁面Ｗ方向に直線状に傾斜した部分とベース基材２２ｂと平行な部分の側壁Ｃｃをもつ平板からなり、このような羽根２２ｆ１〜２２ｆ４がベース基材２２ｂの中心に対して放射状に等間隔で配置されている。このように、羽根２２ｆ１〜２２ｆ４は回転軸側端部Ｅから筐体２１の内部壁面Ｗ方向にかけての側壁Ｃｃ全体が傾斜している必要はない。この場合も各羽根２２ｆ１〜２２ｆ４の側壁Ｃｃの傾斜した部分とベース基材２２ｂとのなす角度（図４におけるβ）が６０°以下であるのが好ましい。この図４に示すような回転体２２であっても、前述の図２、図３の繊維分配装置２０と全く同様の作用効果を奏する。 Figure rotary member 22 of 4 is composed of a base substrate 22b which carries four blades 22f 1 ~22f 4 and (the drawing two only) blade 22f 1 ~22f 4, the blade 22f 1 ~22f 4 is base The center of the material 22b is the end E on the rotating shaft side, and the side wall Cc of the portion that is linearly inclined from the rotating shaft side end E in the direction of the inner wall surface W of the housing 21 and the portion parallel to the base substrate 22b. consists flat with, are arranged at equal intervals radially with respect to the center of such a blade 22f 1 ~22f 4 is the base substrate 22b. As described above, the blades 22f 1 to 22f 4 do not have to have the entire side wall Cc inclined from the rotating shaft side end E toward the inner wall surface W of the housing 21. Also in this case, it is preferable that the angle (β in FIG. 4) formed by the inclined portion of the side wall Cc of each blade 22f 1 to 22f 4 and the base substrate 22b is 60 ° or less. Even the rotating body 22 as shown in FIG. 4 has the same effects as the fiber distributor 20 shown in FIGS.

図５の回転体２２は４枚の羽根２２ｆ１〜２２ｆ４（図面上２枚のみ）と羽根２２ｆ１〜２２ｆ４を担持するベース基材２２ｂとからなり、羽根２２ｆ１〜２２ｆ４はベース基材２２ｂの中心を回転軸側の端部Ｅとし、この回転軸側端部Ｅから筐体２１の内部壁面Ｗ方向に曲線状に傾斜した部分とベース基材２２ｂと平行な部分の側壁Ｃｃをもつ平板からなり、このような羽根２２ｆ１〜２２ｆ４がベース基材２２ｂの中心に対して放射状に等間隔で配置されている。このように、羽根２２ｆ１〜２２ｆ４の側壁Ｃｃは回転軸側端部Ｅから筐体２１の内部壁面Ｗ方向にかけて直線状に延びている必要はない。この場合も各羽根２２ｆ１〜２２ｆ４の側壁Ｃｃの傾斜した部分とベース基材２２ｂとのなす角度（図５におけるγ：ベース基材上における側壁の接線とベース基材とのなす角度）が６０°以下であるのが好ましい。この図５に示すような回転体２２であっても、前述の図２、図３の繊維分配装置２０と全く同様の作用効果を奏する。 Figure rotator 22 5 is composed of a four blades 22f 1 ~22f 4 base substrate 22b which carries (two in the drawing only) and the blade 22f 1 ~22f 4, the blade 22f 1 ~22f 4 is base The center of the material 22b is the end E on the rotating shaft side, and the side wall Cc of the portion inclined in a curved line from the rotating shaft side end E toward the inner wall surface W of the housing 21 and the portion parallel to the base substrate 22b. consists flat with, are arranged at equal intervals radially with respect to the center of such a blade 22f 1 ~22f 4 is the base substrate 22b. Thus, the side walls Cc of the blades 22f 1 to 22f 4 do not need to extend linearly from the rotating shaft side end E toward the inner wall surface W of the housing 21. Again the angle between the inclined portion and the base substrate 22b of the side wall Cc of each vane 22f 1 ~22f 4 (γ in Figure 5: the angle between the tangent line and the base material of the side wall on the base substrate) is It is preferably 60 ° or less. Even the rotating body 22 as shown in FIG. 5 has the same effects as the fiber distributor 20 shown in FIGS.

なお、図示しないが、回転体２２の羽根２２ｆ１〜２２ｆ４は平板からなる必要はなく、竹とんぼのように平板を湾曲させたような状態にあっても良い。また、回転体２２の羽根２２ｆ１〜２２ｆ４はベース基材２２ｂの中心に対して放射状に配置されている必要はなく、ベース基材２２ｂの中心からの放射線に対して交差するように配置していても良い。更には、羽根２２ｆ１〜２２ｆ４の側壁Ｃｃの回転軸側端部Ｅがベース基材２２ｂの中心と一致する必要はなく、ベース基材２２ｂの中心と外周の間にあっても良い。 Although not shown, the blades 22f 1 to 22f 4 of the rotating body 22 do not have to be flat plates, and may be in a state where the flat plates are curved like bamboo dragonflies. Also, the blade 22f 1 ~22f 4 of the rotating body 22 need not be arranged radially with respect to the center of the base member 22b, and arranged so as to intersect the radiation from the center of the base substrate 22b May be. Furthermore, you are not necessary to have rotational shaft side end portion E of the side wall Cc of the blade 22f 1 ~22f 4 coincides with the center of the base substrate 22b, may be between the center and outer periphery of the base substrate 22b.
