本発明の目的は、付着性繊維束を振動スクリーン上で振動させて個々のａ雑に解 離し、解離されたｔａ維をスクリーンの長形開口を通過させることにより、上記 開口を通過する前のｔａ維がスクリーンの振動運動によってスクリーンに平行な 平面上に揃えられ、上記開口が主として一度に一本の繊維のみが同一開口を通過 できるような形状を有し、上記解ｇ！繊維が重力および振動力によって広い面積 にわたって上記混合装置に供給され、上記面積が上記スクリーンの面積より大き いことを特徴とする特許請求範囲１記載の方法によって達成される。The object of the present invention is to vibrate adhesive fiber bundles on a vibrating screen to separate them into individual a. The above-described Before passing through the aperture, the TA fibers are moved parallel to the screen by the vibrating motion of the screen. Aligned on a plane, the above apertures primarily allow only one fiber to pass through the same aperture at a time. It has a shape that allows the above solution g! The fibers are spread over a large area by gravity and vibration forces. is supplied to the mixing device over the area, and the area is larger than the area of the screen. This is achieved by the method according to claim 1, characterized in that:
本方法を実施するスクリーンは、長形開口を有し、開口の長さが主として上記繊 維の長さに等しく、その幅が上記繊維の長さより実質、的に小さいふるい分は手 段から次に本発明を図面に基づいて説明する。The screen for carrying out this method has elongated openings, and the length of the openings is mainly for the above-mentioned fibers. The portion of the sieve that is equal to the length of the fibers and whose width is substantially smaller than the length of the fibers is hand-sealed. The present invention will be explained from stage to stage based on the drawings.
第１図は本発明のスクリーンで構成されるコンクリートミキサー装置の断面図で あり、第２図は上記コンクリートミキサー装置の上視図である。Figure 1 is a cross-sectional view of a concrete mixer device comprising the screen of the present invention. 2 is a top view of the concrete mixer device.
第１図に示すコンクリートミキサー装置は、図示されていない混合機構を有する 混合手段１を備え、上記混合ｍ構はモーター２によって駆動される。混合手段１ 上にはスクリーン３が配設され、スクリーン３はふるい分は手段４を備えている 。上記ふるい分は手段は、モーター５により偏心部材６を介して振動運動を与え られる。上記ふるい分は手段４は、たとえば第２図に示す菱形開口のごとき長形 開口８を有する。The concrete mixer device shown in Figure 1 has a mixing mechanism not shown. A mixing means 1 is provided, and the mixing mechanism is driven by a motor 2. Mixing means 1 A screen 3 is arranged above, and the screen 3 is equipped with means 4 for sieving. . The means for the above-mentioned sieve is to apply vibrational motion via an eccentric member 6 by a motor 5. It will be done. The means 4 for the above-mentioned sieve is a long one with a diamond-shaped opening as shown in FIG. 2, for example. It has an opening 8.
スクリーン３は、上記ふるい分は手段が前後に移動する際にスクリーンに供給さ れる繊維を保持する側壁７を備えている。ふるい分は手段４は混合手段１の大き い面積部分を覆っている。この被覆面積はできるだけ大きいことが望ましい。第 ２図において五ろい分は手段の幅は円形混合槽１の半径の約半分である。ふるい 分は手段は、繊維がすべて混合槽１内に落下するような長さを有する。The screen 3 is such that the sieve portion is supplied to the screen when the means moves back and forth. It has a side wall 7 for holding fibers to be collected. The sieve portion is the size of the mixing means 1. It covers a large area. It is desirable that this covered area be as large as possible. No. In Figure 2, the width of the five-point means is approximately half the radius of the circular mixing tank 1. sieve The length of the means is such that all the fibers fall into the mixing tank 1.
当然のこととして、このスクリーンを混合槽の中心に近ずける程、その長さおよ び幅を増大させることができる。Naturally, the closer this screen is to the center of the mixing tank, the longer it will be. The width can be increased.
モーター５の回転数を変化させることによって、上記ふるい分は手段の速度なら びに繊維の供給量を増減することができる。By changing the rotational speed of the motor 5, the above sieve can be adjusted at the speed of the means. The amount of fiber supplied can be increased or decreased at any time.
ふるい分は手段の開口は長形であって好ましくは長菱形、すなわち長方形および 菱形の両方を含むことが望ましい。開口の形状は、主として一度に一本のａ維の みが同一の開口を通過できるものであることが必要である。The opening of the sieve means is elongated, preferably oblong, i.e. rectangular and It is desirable to include both rhombuses. The shape of the aperture is primarily for one a-fiber at a time. It is necessary that all the components can pass through the same opening.
開口の最大寸法は１ａ雑の長さと同程度であり、最長寸法に垂直な寸法は二本以 上付着した繊維が通過できないものでなければならない。長菱形開口の実用最小 寸法は、隣接する二辺の長さの合計が繊維の長さよりやや大きいものである。こ の場合、長軸がふるい分は手段の面に対しである角度を持つ繊維のみが通過可能 である。長菱形開口の好ましい実用最大寸法は隣接する二辺の長さの合計が繊維 の長さの二倍のものである。当然のこととして開口幅は、はとんどの場合に二本 以上の繊維の束が通過できないものでなければならない。ふるい分は手段の面は 平面ではなく、突出部と対応する凹部（負の突出）を備え、上面の高さが規則的 あるいは不規則な変化を有することが望ましい。The maximum dimension of the opening is about the same as the length of 1A, and the dimension perpendicular to the longest dimension is two or more. It must not allow the fibers attached to the top to pass through. Practical minimum long rhombus opening The dimensions are such that the sum of the lengths of two adjacent sides is slightly larger than the length of the fiber. child In the case of , only fibers whose long axes have a certain angle to the plane of the sieve can pass through. It is. The preferred practical maximum dimension of an oblong rhombus opening is that the sum of the lengths of two adjacent sides is the length of the fiber. It is twice the length of . Naturally, the opening width is usually two. It must be impossible for a bundle of fibers to pass through. The sieve is the means Rather than being flat, it has protrusions and corresponding recesses (negative protrusions), and the height of the top surface is regular. Alternatively, it is desirable to have irregular changes.
好ましいふるい分は手段の一例は、エクスパンデッドメタル製の菱形開口を有す るものである。このエクスパンデッドメタル製開口はふるい分は手段の面に対し て鋭角をなしている。−例としで、長さ１８胴の繊維に対しては、開口の最大対 角線が２５ｍ＋ａ、短い対角綿が１２ｍ＋ｍの菱形開口を有するエクスパンデッ ドメタルスクリーンが極めて適している。開口寸法は繊維の長さによって異なる 。An example of a preferred sieve means is a sieve with diamond-shaped openings made of expanded metal. It is something that This expanded metal aperture has a sieve portion relative to the surface of the means. It forms an acute angle. - As an example, for a fiber of length 18, the maximum number of openings An expand deck with a diamond-shaped opening of 25 m + a square wire and 12 m + m short diagonal cotton. A metal screen is extremely suitable. Opening dimensions vary depending on fiber length .
本発明の方法を用いろ場合、ｗＡ維は繊維束の形で供給され、単繊維ももちろん 使用可能である。この繊維束を；ンドレスチェインエ、レベーター９１１でスク リーン３に供給し、スクリーン３は上記混合槽１の上に直接配設されている。混 合手段］には同時にまたは好ましくはあらかじめ湿った砂を投入する。この砂は 乾燥したものであってはならない。上記ふるい分は手段を通して、主として一度 に一本のｔａ維のみが同一の開口を通過するため、単位時間当り多数の繊維を広 い面積にわたって供給することができる。したがって混合槽内で詰まることなく 多量の繊維を供給できる。スクリーンが振動していることにより、繊維はふるい 分は手段の面に平行な運動成分を与えられる。したがってＷ４維はふるい分は手 段の面積より大きい範囲にわな、って広がる。混合装置１は、コンクリート中の 繊維が互に付着する前に分散させろ。引き続き、できれば同時に、砂と共に他の 骨材たとえば二酸イピ珪素を添加する。骨材に続いてセメント、次いで水を加え て混合コンクリートを生成する。このコンクリートは、吹き付は施工することが できる。この吹き付けによって繊維がコンクリ−゛ト中で・一方向に揃えられる 。When using the method of the present invention, wA fibers are supplied in the form of fiber bundles, not only single fibers but also single fibers. Available for use. Scrub this fiber bundle using a chainless chainer and a lever 911. The screen 3 is placed directly above the mixing tank 1. Mixed At the same time or preferably in advance, wet sand is added to the mixing means]. This sand It should not be dry. The above-mentioned sieve amount is mainly processed once through the means. Since only one TA fiber passes through the same aperture in a given time, many fibers can be spread out per unit time. It can be supplied over a large area. Therefore, there will be no clogging in the mixing tank. A large amount of fiber can be supplied. As the screen vibrates, the fibers are sieved. minute is given a motion component parallel to the plane of the means. Therefore, for W4 fibers, the sieve is handled by hand. It spreads like a trap over an area larger than the area of the step. The mixing device 1 mixes Disperse the fibers before they stick together. Continue, preferably at the same time, along with other Aggregates such as ipisilicon diacid are added. Add aggregate followed by cement and then water to produce mixed concrete. This concrete cannot be applied by spraying. can. This spraying aligns the fibers in one direction in the concrete. .
