Description

【0001】
【発明の属する技術分野】
この発明は、樹脂加工液や洗浄液を含み拡布状態で走行する湿潤布帛を吸引により脱液するための装置に関し、幅方向に長い吸引ノズルの端部側において布帛と接触しない開口部分を布帛幅の変動に応じて自動的に塞ぐものである。
【0002】
【従来の技術】
布帛を拡布状態で走行させながら布帛に洗浄液を噴射し、これを強制的に貫流させて洗浄するため、また単なる洗浄後の脱液や樹脂加工液に浸漬後の脱液等を目的として、拡布状態で走行する湿潤布帛を、該布帛の幅方向に長い固定式の吸引ノズルに接触させ、吸引により脱液するようにしたものが知られている。
【0003】
このような脱液装置では、吸引ノズルが布帛の幅方向に長く作られるため、布帛のロットによっては、吸引ノズルの両端側が布帛の幅方向外側に大きくはみだし、吸引ノズルのスリットの中央部のみが布帛で塞がれ、端部側は布帛に塞がれることなく開口状態となり、そのため余分の空気が吸引されてエネルギのロスが大きくなっていた。そこで、上記のスリットが布帛の外側にはみ出した部分を手動で塞ぐためのシャッターが開発されたが、この手動シャッターは、走行中に布帛が蛇行したり、布帛幅が変動したりするのに対して追従できないため、吸引エネルギのロスを防ぐには不十分であった。
【0004】
また、上記吸引ノズルの布帛幅方向外側のスリットを塞ぐように該スリットに沿って柔軟なゴムまたは合成樹脂からなるチューブを這わせ、該チューブの一端を吸引ノズルの外側端部に固定し、他端を布帛の幅方向内側上方から引張りコイルスプリング等で引き上げ、布帛の耳が内側に移動してスリットが開くと、チューブが吸引力で下がってスリットを塞ぎ、布帛の耳が外側に移動すると、チューブが上記スプリングの弾力で上昇してスリットから離れ、スリットが布帛で塞がれるようにしたものが開発されたが、この場合はチューブを用い、その内方端部をスプリングで引張るので、吸引ノズルからの吸引力でスリットを塞ぐためには、大きい吸引力が必要になり、そのため布帛幅が吸引ノズルの全幅(布帛幅方向の寸法)に対して著しく狭くなった場合および吸引初期においてシール性が不十分となり、吸引力を大きくすると、布帛の耳が外側へ移動する際に耳折れが生じ易い等の問題があった。
【0005】
【発明が解決しようとする課題】
この発明の課題は、拡布状態で走行する布帛の吸引脱液装置において、幅方向に長い吸引ノズルのスリットが布帛と接触せずに開口する部分を布帛の蛇行や布帛幅の変動に応じて自動的に、かつ円滑に塞ぎ、しかも布帛幅が吸引ノズルの全幅に対して著しく狭くなった場合および吸引初期においても比較的低い吸引力で良好にシールし、吸引エネルギを節約することである。
【0006】
【課題を解決するための手段】
この発明に係る走行布帛の吸引脱液装置は、任意の処理液を含浸した布帛を拡布状態で走行させ、その片面を幅方向に長い吸引ノズルの先端に接触させて脱液するようにした走行布帛の吸引脱液装置において、上記吸引ノズルの先端に対向してゴム状弾性を有する方形のシャッター膜を、その幅方向の一部が吸引ノズル先端との間に走行布帛を挟んで走行布帛に重なり、残りの部分が走行布帛の幅方向外側に延びるように上記の走行布帛と平行に、かつ布帛走行方向に対して前後の縁を固定する形に張設してなり、上記のシャッター膜に布帛走行方向に対して傾斜する多数本の直線状切込みが幅方向に等間隔に、かつその傾斜方向が布帛中心線に対し左側の切込みおよび右側の切込みの間隔を布帛走行方向に向かって広げる方向に並設され、上記布帛の走行時に上記シャッター膜が走行布帛と重なる部分では吸引ノズル先端から走行布帛によって分離され、走行布帛の幅方向外側に延びる部分では吸引ノズル先端に吸引力で吸着されて該先端を塞ぐようにしたことを特徴とする。
【0007】
上記の装置において、吸引ノズルの先端と該先端を覆うシャッター膜との間に拡布状態の布帛を通し、この布帛を所定の速度で走行させ、吸引ノズルに吸引力を作用させると、シャッター膜が布帛に重なる部分では、布帛が吸引ノズル先端に接し、布帛に吸引力が作用して布帛の脱液が行われる。そして、シャッター膜には吸引ノズルの吸引力が作用しないため、シャッター膜は、その弾性によって収縮し、布帛から離れる。
【0008】
一方、シャッター膜が布帛の幅方向外側へ延びる部分は、シャッター膜に吸引ノズルの吸引力が直接作用するため、シャッター膜が吸引ノズル側に引っ張られ、吸引ノズル先端に吸着されて該先端を塞ぐ。このとき、シャッター膜はゴム状弾性を備えるため、シール性が良好である。そして、布帛の蛇行や布帛幅の変動により、布帛の耳部が吸引ノズル先端上を左右に移動すると、この移動に応じて自動的にシャッター膜の吸引ノズル先端に接する部分が幅方向に伸縮する。したがって、布帛の耳よりも幅方向外側の吸引ノズル先端は、常にシャッター膜の良好なシール性で塞がれ、そのためエネルギが節約される。
【0009】
上記のシャッター膜は、方形に形成されて布帛と平行に配置され、布帛の走行方向に対して前後の縁を固定する形に張設されるが、吸引ノズルに対し全ロットの布帛が常に接する部分、すなわち吸引ノズルの幅方向中央には設ける必要がない。脱液されるべき布帛の最小幅よりも若干狭い部分を残し、その左右両側にシャッター膜を設けることで足りる。また、シャッター膜の厚さや弾性は、吸引ノズル先端のスリットに作用する吸引力および吸引ノズル先端からシャッター膜までの距離等に応じ、スリットを円滑に開閉できる程度に設定される。なお、吸引ノズル先端の吸引力は、布帛の種類にもよるが、通常の場合、−20〜−40kpa が好ましく、−20kpa 未満の場合は脱液不十分となり、反対に−40kpa を超えると脱液効果が飽和に達して不経済である。
【0010】
上記のシャッター膜には、多数本の直線状切込みを布帛走行方向に対して傾斜させ、かつ幅方向に等間隔に並設することができる。すなわち、幅が狭く、布帛走行方向に長い、好ましくは幅が5〜15mm、長さが50〜100mmのテープ状シャッター膜を多数本、互いに重ならないように、かつ隙間なく幅方向に並列し、前後の両端を固定して設けることができる。この場合は、シャッター膜が上記の切込みで形成される狭い幅のテープ状部分を単位として動き、布帛の耳がテープ状シャッター膜の縁と点接触するので、吸引力が弱くても布帛耳部の移動に対するシャッター膜の開閉動作が円滑になり、シール性が向上する。なお、切込みの傾斜角度は、5〜30度が好ましく、5度未満では布帛の耳が外向きに移動するとき引っ掛かり易く、30度を超えるとシール性が低下する。
【0011】
切込みの傾斜方向は、布帛中心線に対し左側の切込みおよび右側の切込みの距離が布帛走行方向に向かって広がる方向に設定することが特に好ましい。換言すれば、布帛中心線の左右に並ぶ多数本のテープ状シャッター膜を、布帛走行方向に向かって布帛中心線から離れる向きに傾斜させる。この場合は、前記同様にシャッター膜が狭い幅のテープ状部分を単位として動くので、シャッター膜の開閉動作が円滑になり、しかもシャッター膜の切込みが外向きに傾斜しているので、布帛幅が広がったり、布帛が蛇行したりして耳部が外向きに移動するとき、その移動が一層円滑になり、布帛の耳折れが防止される。
【0012】
【発明の実施の形態】
図1は吸引脱液装置10の正面図、図2はその平面図である。この吸引脱液装置10は、一方向に細長く作られ、布帛Fの走行通路(この実施形態では上から下向きに設定される)を横断するように水平に設置される。なお、図1では、吸引脱液装置10の右半部が示される。この吸引脱液装置10は、角筒状の本体フレーム11とその前面に開口する長孔11a(図4、図5参照)を挟んで固定された上下1組のノズルプレート12とで構成され、本体フレーム11の背面側両端に位置する足板11bを介して支持フレーム14に固定される。そして、本体フレーム11の端板11cに固定された円形パイプ13(図3参照)を介してブロア(図示されていない)が接続される。
【0013】
上記のノズルプレート12は、本体フレーム11の前面に突出する吸引ノズルを構成し、前記の布帛Fはこの吸引ノズル12の先端に接するように適当なガイドローラ等を介して拡布状に案内される。なお、上記のノズルプレート12は、山形鋼で形成され、その2枚によって先端に形成されるスリット12aの幅dは、2〜5mmの範囲で調節自在に形成され、また上記のスリット12aに作用する吸引力は、前記のブロアによって−20〜−40kpa に設定される。
【0014】
上記本体フレーム11の前方に間隔を空けてシャッター枠15(図1および図2参照)が設けられる。このシャッター枠15は、本体フレーム11のほぼ全域にまたがる平板の中央および左右の3箇所に横長の窓孔15aを開けたものであり、その四隅に突設した脚部15bを介して上記本体フレーム11に固定され、この本体フレーム11に固定されている前記吸引ノズル12の先端とシャッター枠15との間に空隙が形成される。
【0015】
このシャッター枠15の左右2箇所にそれぞれシャッター膜16が張設される。このシャッター膜16は、方形のゴムシートからなり、図1において、幅(横寸法)が窓孔15aよりも小さく、長さ(縦寸法)がシャッター枠15よりも大きく形成され、その中央部に中心線Nに対して若干傾斜する多数本の切込み16aを互いに平行に、かつ幅方向に等間隔に並設したものである。なお、上記の切込み16aにおいて、その傾斜角度θは中心線Nに対して5〜30度に設定され、その間隔は5〜15mmに設定される。
【0016】
そして、上記のシャッター膜16は、シャッター枠15の背面(本体フレーム11側)に重ねられ(図4および図5参照)、上下の縁部をシャッター枠15の縁に沿って手前に折り返し、シャッター枠15の前面の縁に重ね、更にその上に押えバー17を重ねて複数本のボルト18で固定される。
【0017】
上記の構造において(図1および図2参照)、布帛Fを拡布状態で走行させながら洗浄液を含浸させ、しかるのち上記吸引脱液装置10の幅方向中央の吸引ノズル12とシャッター膜16との間に(図5参照)上から下向きに導入し、吸引脱液装置10に接続されているブロアを駆動し、吸引ノズル12のスリット12aに吸引力を作用させると、布帛Fは吸引ノズル12の先端に接しながら走行し、スリット12aに働く吸引力によって脱液される。そして、この布帛Fに面するシャッター膜16は、吸引されることなくその弾性で収縮し、布帛Fから離れて静止し、布帛Fとほぼ平行な状態を維持する。
【0018】
他方、布帛Fの耳よりも幅方向外側のシャッター膜16は、図4に示すように、吸引ノズル12の吸引力を受けて吸引ノズル12側に引っ張られ、吸引ノズル12の先端に吸着されてスリット12aを塞ぐ。そして、布帛Fの幅の変動または蛇行により、布帛Fの耳が吸引ノズル12の先端に沿って左右に移動すると、この移動に追随して上記シャッター膜16のスリット12aを塞ぐ位置が自動的に変化し、布帛Fの耳よりも外側のスリット12aは常に塞がれる結果になり、そのシール性も良好である。
【0019】
そして、この実施形態では、シャッター膜16の切込み16aが布帛Fの走行方向に向かって中心線Nから離れる方向に傾斜しているため、シャッター膜16によるスリット12aの開閉が極めて円滑に行われ、布帛Fの耳が幅方向外向きに移動する場合にも耳折れが生じない。
【0020】
【発明の効果】
上記のとおり、この発明に係る走行布帛の吸引脱液装置は、布帛の耳よりも幅方向外側にあって布帛と接触せずに開口する吸引ノズルのスリットを布帛の蛇行や布帛幅の変動に応じて自動的に塞ぐことができ、そのシール性も良好であり、また吸引ノズルに働く吸引力を利用し、他の動力を利用しないので、大幅な省力が可能になり、構造も簡略化される。そして、吸引ノズルのシャッターとしてゴム状弾性を有する膜を用い、これを吸引ノズルの先端に対向して張設するので、吸引ノズルの先端に沿ってチューブを這わせたものに比べ、比較的低い吸引力でシール動作を開始することができ、始動直後におけるブロアの回転上昇を少なくでき、かつ布帛の幅が吸引ノズルの全幅に対して著しく狭い場合も良好なシール性が得られる。
【0021】
そして、吸引力が弱くても布帛耳部の移動に対するシャッター膜の開閉動作が円滑になり、シール性が一層向上し、かつ布帛の耳部が外向きに移動する際の布帛の耳折れを防止することができる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to an apparatus for removing liquid by suction of a wet cloth running in a spread state containing a resin processing liquid or a cleaning liquid, and an opening portion not in contact with the cloth at an end side of a suction nozzle that is long in the width direction has a width equal to the cloth width. It is automatically closed according to the fluctuation.
[0002]
[Prior art]
The cleaning liquid is sprayed onto the cloth while the cloth is running in the spread state, and the cleaning liquid is forcibly passed through to wash the cloth. It is known that a wet cloth running in a state is brought into contact with a fixed suction nozzle that is long in the width direction of the cloth, and is drained by suction.
[0003]
In such a liquid removing device, since the suction nozzle is made long in the width direction of the fabric, depending on the lot of the fabric, both end sides of the suction nozzle protrude largely outward in the width direction of the fabric, and only the central portion of the slit of the suction nozzle is formed. The fabric was closed, and the end portion was opened without being closed by the fabric. Therefore, excess air was sucked and energy loss was increased. Therefore, a shutter has been developed for manually closing the portion where the above-mentioned slit has protruded outside of the fabric.However, this manual shutter has a configuration in which the fabric meanders or the width of the fabric fluctuates during traveling. Therefore, it was not enough to prevent a loss of suction energy.
[0004]
Further, a tube made of a flexible rubber or synthetic resin is laid along the slit so as to cover the slit on the outer side in the fabric width direction of the suction nozzle, and one end of the tube is fixed to the outer end of the suction nozzle. When the end is pulled up from the upper side in the width direction of the fabric with a tension coil spring or the like, and the ear of the fabric moves inward and the slit opens, the tube goes down with suction force to close the slit, and when the ear of the fabric moves outward, A tube has been developed in which the tube rises with the elasticity of the spring and separates from the slit, so that the slit is closed with a cloth.In this case, a tube is used and its inner end is pulled by a spring, so suction is performed. In order to close the slit with the suction force from the nozzle, a large suction force is required. Therefore, the fabric width is significantly different from the entire width of the suction nozzle (the dimension in the fabric width direction). Sealability becomes insufficient when narrowed and aspiration initial, increasing the suction force, cloth ear ear broken there is a problem of easily such occur when moving outward.
[0005]
[Problems to be solved by the invention]
SUMMARY OF THE INVENTION An object of the present invention is to provide a suction and dewatering apparatus for a cloth running in an expanded state, in which a slit of a suction nozzle that is long in the width direction opens without contacting the cloth, according to the meandering of the cloth or the fluctuation of the cloth width. In other words, when the cloth width is remarkably narrowed with respect to the entire width of the suction nozzle and at the initial stage of suction, the seal is satisfactorily sealed with a relatively low suction force to save suction energy.
[0006]
[Means for Solving the Problems]
The suction and dewatering apparatus for a traveling cloth according to the present invention travels a cloth impregnated with an arbitrary processing liquid in an expanded state, and contacts one end of the cloth with the tip of a suction nozzle that is long in the width direction to perform liquid removal. In the cloth suction and dewatering device, a rectangular shutter film having rubber-like elasticity is opposed to the tip of the suction nozzle, and a part of the width direction of the shutter film is formed on the traveling cloth with the traveling cloth sandwiched between the suction nozzle and the tip. overlapping, parallel to the above traveling fabric as the rest of extending outward in the width direction of the traveling fabric, and it was stretched in the form of fixing the front and rear edges relative to the fabric running direction, to the shutter membrane A direction in which a large number of linear cuts inclined with respect to the cloth running direction are arranged at equal intervals in the width direction, and the inclination direction is such that the gap between the left cut and the right cut is widened in the cloth running direction with respect to the fabric center line. They are arranged in parallel in, When the cloth is running, the shutter film is separated from the tip of the suction nozzle by the running cloth in a portion where the shutter film overlaps with the running cloth, and the portion extending outward in the width direction of the running fabric is sucked by the suction nozzle tip by a suction force to close the tip. It is characterized in that.
[0007]
In the above-described apparatus, the cloth in the spread state is passed between the tip of the suction nozzle and the shutter film covering the tip, and the cloth is run at a predetermined speed to apply a suction force to the suction nozzle. In a portion overlapping with the fabric, the fabric comes into contact with the tip of the suction nozzle, and a suction force acts on the fabric to remove the fabric. Since the suction force of the suction nozzle does not act on the shutter film, the shutter film contracts due to its elasticity and separates from the cloth.
[0008]
On the other hand, in the portion where the shutter film extends outward in the width direction of the fabric, since the suction force of the suction nozzle directly acts on the shutter film, the shutter film is pulled toward the suction nozzle side and is sucked by the suction nozzle tip to close the tip. . At this time, since the shutter film has rubber-like elasticity, the sealing property is good. Then, when the ears of the cloth move right and left on the suction nozzle tip due to the meandering of the cloth and the fluctuation of the cloth width, the portion of the shutter film that is in contact with the suction nozzle tip automatically expands and contracts in the width direction according to this movement. . Therefore, the tip of the suction nozzle on the outer side in the width direction than the ear of the fabric is always closed by the good sealing property of the shutter film, and thus energy is saved.
[0009]
The above-described shutter film is formed in a rectangular shape and arranged in parallel with the fabric, and is stretched so as to fix the front and rear edges with respect to the running direction of the fabric, but the fabric of all lots always contacts the suction nozzle. It is not necessary to provide a portion, that is, a center in the width direction of the suction nozzle. It is sufficient to provide a shutter film on both the left and right sides, leaving a portion slightly smaller than the minimum width of the cloth to be drained. The thickness and elasticity of the shutter film are set to such an extent that the slit can be smoothly opened and closed according to the suction force acting on the slit at the tip of the suction nozzle and the distance from the tip of the suction nozzle to the shutter film. Although the suction force at the tip of the suction nozzle depends on the type of the fabric, it is usually preferably -20 to -40 kpa, and if it is less than -20 kpa, the liquid is insufficiently removed. The liquid effect reaches saturation and is uneconomical.
[0010]
In the shutter film, a large number of linear cuts can be inclined with respect to the running direction of the fabric, and can be juxtaposed at equal intervals in the width direction. That is, the width is narrow, long in the cloth running direction, preferably 5 to 15 mm in width, a number of tape-shaped shutter films of 50 to 100 mm in length, so that they do not overlap each other, and are arranged in parallel in the width direction without gaps, The front and rear ends can be fixed. In this case, the shutter film moves in units of a narrow tape-shaped portion formed by the above-mentioned cut, and the ears of the fabric make point contact with the edge of the tape-shaped shutter film. The opening and closing operation of the shutter film with respect to the movement of the shutter becomes smooth, and the sealing property is improved. In addition, the inclination angle of the cut is preferably 5 to 30 degrees, and if it is less than 5 degrees, the ear of the fabric is likely to be caught when moving outward, and if it exceeds 30 degrees, the sealing property is reduced.
[0011]
It is particularly preferable that the inclination direction of the cut is set so that the distance between the cut on the left side and the cut on the right side with respect to the fabric center line increases in the cloth running direction. In other words, a large number of tape-shaped shutter films arranged on the left and right of the fabric center line are inclined in a direction away from the fabric center line in the fabric running direction. In this case, as described above, the shutter film moves in units of tape-like portions having a narrow width, so that the opening and closing operation of the shutter film is smooth, and the cut of the shutter film is inclined outward, so that the fabric width is reduced. When the ears move outward due to spreading or meandering of the fabric, the movement becomes smoother, and the ears of the fabric are prevented from breaking.
[0012]
BEST MODE FOR CARRYING OUT THE INVENTION
FIG. 1 is a front view of the suction and dewatering device 10, and FIG. 2 is a plan view thereof. The suction and dewatering device 10 is elongated in one direction, and is horizontally installed so as to cross a travel path of the fabric F (set from top to bottom in this embodiment). FIG. 1 shows the right half of the suction / liquid removing device 10. The suction and dewatering device 10 is composed of a rectangular cylindrical main body frame 11 and a pair of upper and lower nozzle plates 12 fixed with an elongated hole 11a (see FIGS. 4 and 5) opened on the front surface thereof. The main frame 11 is fixed to the support frame 14 via foot plates 11b located at both ends on the rear side. Then, a blower (not shown) is connected via a circular pipe 13 (see FIG. 3) fixed to the end plate 11c of the main body frame 11.
[0013]
The nozzle plate 12 constitutes a suction nozzle protruding from the front surface of the main body frame 11, and the cloth F is guided in an expanded manner via an appropriate guide roller or the like so as to contact the tip of the suction nozzle 12. . The nozzle plate 12 is made of angle iron, and the width d of the slit 12a formed at the tip of the nozzle plate 12 is formed to be adjustable within a range of 2 to 5 mm, and acts on the slit 12a. The suction force is set to -20 to -40 kpa by the blower.
[0014]
A shutter frame 15 (see FIGS. 1 and 2) is provided at an interval in front of the main body frame 11. The shutter frame 15 is formed by opening horizontally long window holes 15a at the center and at three places on the left and right sides of a flat plate extending over substantially the entire area of the main body frame 11. The main body frame 11 is provided with legs 15b projecting from four corners thereof. A gap is formed between the shutter frame 15 and the tip of the suction nozzle 12 fixed to the main body frame 11.
[0015]
Shutter films 16 are provided at two positions on the left and right of the shutter frame 15, respectively. The shutter film 16 is formed of a square rubber sheet. In FIG. 1, the width (horizontal dimension) is smaller than the window hole 15a and the length (vertical dimension) is greater than the shutter frame 15 in FIG. A large number of cuts 16a slightly inclined with respect to the center line N are arranged in parallel with each other and at equal intervals in the width direction. In the above-mentioned cut 16a, the inclination angle θ is set to 5 to 30 degrees with respect to the center line N, and the interval is set to 5 to 15 mm.
[0016]
Then, the shutter film 16 is superposed on the back surface (the main body frame 11 side) of the shutter frame 15 (see FIGS. 4 and 5), and the upper and lower edges are folded back along the edge of the shutter frame 15 to close the shutter. The frame 15 is placed on the front edge of the frame 15, and the holding bar 17 is further placed thereon, and is fixed with a plurality of bolts 18.
[0017]
In the above-described structure (see FIGS. 1 and 2), the fabric F is impregnated with the cleaning liquid while running in the spread state, and then, between the suction nozzle 12 at the center in the width direction of the suction and dewatering device 10 and the shutter film 16. (See FIG. 5), the blower connected to the suction and dewatering device 10 is driven to apply a suction force to the slit 12 a of the suction nozzle 12. , And is drained by the suction force acting on the slit 12a. The shutter film 16 facing the fabric F contracts due to its elasticity without being sucked, separates from the fabric F and stops, and maintains a state substantially parallel to the fabric F.
[0018]
On the other hand, the shutter film 16 on the outer side in the width direction from the ear of the fabric F is pulled toward the suction nozzle 12 by the suction force of the suction nozzle 12 as shown in FIG. Block 12a. When the width of the fabric F changes or the meandering causes the ears of the fabric F to move left and right along the tip of the suction nozzle 12, the position for closing the slit 12a of the shutter film 16 automatically follows the movement. As a result, the slits 12a outside the ears of the fabric F are always closed, and the sealing property is good.
[0019]
And in this embodiment, since the cut 16a of the shutter film 16 is inclined in the direction away from the center line N toward the running direction of the fabric F, the opening and closing of the slit 12a by the shutter film 16 is performed extremely smoothly, Even when the ears of the fabric F move outward in the width direction, the ears do not break.
[0020]
【The invention's effect】
As described above, the suction / liquid removing device for a traveling fabric according to the present invention is configured such that the slit of the suction nozzle, which is located outside of the ear of the fabric in the width direction and opens without contacting the fabric, responds to the meandering of the fabric and the fluctuation of the fabric width. It can be closed automatically, has good sealing properties, and uses the suction force acting on the suction nozzle, and does not use other power, so it is possible to save a great deal of labor and simplify the structure. . And, since a film having rubber-like elasticity is used as a shutter of the suction nozzle and is stretched so as to face the tip of the suction nozzle, it is relatively lower than that in which a tube is run along the tip of the suction nozzle. The sealing operation can be started by the suction force, the rise in the rotation of the blower immediately after the start can be reduced, and good sealing properties can be obtained even when the width of the fabric is extremely narrow with respect to the entire width of the suction nozzle.
[0021]
Even if the suction force is weak, the opening / closing operation of the shutter film with respect to the movement of the fabric ears becomes smooth, the sealing performance is further improved , and the ears of the fabric are prevented from breaking when the ears move outward. can do.

任意の処理液を含浸した布帛を拡布状態で走行させ、その片面を幅方向に長い吸引ノズルの先端に接触させて脱液するようにした走行布帛の吸引脱液装置において、上記吸引ノズルの先端に対向してゴム状弾性を有する方形のシャッター膜を、その幅方向の一部が吸引ノズル先端との間に走行布帛を挟んで走行布帛に重なり、残りの部分が走行布帛の幅方向外側に延びるように上記の走行布帛と平行に、かつ布帛走行方向に対して前後の縁を固定する形に張設してなり、上記のシャッター膜に布帛走行方向に対して傾斜する多数本の直線状切込みが幅方向に等間隔に、かつその傾斜方向が布帛中心線に対し左側の切込みおよび右側の切込みの間隔を布帛走行方向に向かって広げる方向に並設され、上記布帛の走行時に上記シャッター膜が走行布帛と重なる部分では吸引ノズル先端から走行布帛によって分離され、走行布帛の幅方向外側に延びる部分では吸引ノズル先端に吸引力で吸着されて該先端を塞ぐようにしたことを特徴とする走行布帛の吸引脱液装置。In a suction and dewatering apparatus for a traveling cloth, the cloth impregnated with an arbitrary processing liquid is run in an expanded state, and one side of the cloth is contacted with the end of a suction nozzle that is long in the width direction to perform liquid removal. A rectangular shutter film having rubber-like elasticity faces the traveling cloth with a part thereof in the width direction sandwiching the traveling cloth between the suction nozzle and the tip of the suction nozzle, and the remaining part extends outward in the width direction of the traveling cloth. A large number of straight lines inclined in the shutter film with respect to the cloth running direction are stretched in parallel with the running cloth so as to extend and fixing the front and rear edges with respect to the cloth running direction. The cuts are arranged at equal intervals in the width direction, and the inclination direction thereof is juxtaposed in such a direction that the gap between the cuts on the left side and the cuts on the right side with respect to the center line of the fabric is increased in the cloth running direction. Traveling The traveling cloth is separated from the tip of the suction nozzle by the traveling fabric at a portion overlapping with the fabric, and the portion extending outward in the width direction of the traveling fabric is suctioned to the tip of the suction nozzle by a suction force to close the tip. Suction dewatering device.
