【０００３】
【発明が解決しようとする課題】
従来の風綿処理装置は、回収室へ集められた風綿を定期的に手作業で排出して次の処理工程へ搬送せねばならない。しかし、回収室へ集められた風綿は、多くの空気を含む嵩高のため、取り扱い難く作業者に多くの手間を負担させる結果となっている。
【０００４】
そこで、本発明は、上記問題を解決するために、風綿を扱い易い状態にして作業者の手間を軽減することができる風綿処理装置の提供を目的とする。
【０００５】
【課題を解決するための手段】
請求項１記載の本発明が採用した手段は、風綿付着用フィルターを設けた集綿室と、集綿室に隣接する回収室と、集綿室の風綿付着用フィルターに付着している風綿を回収室へ集める回収手段と、風綿付着用フィルターを配置したバイパス室と、集綿室及びバイパス室の各空気出口側と吸気室の間に介在するダンパーと、これらダンパーの開閉を自動で行うダンパー操作具を備え、ダンパー操作具の開閉操作で、一方のダンパーが開いて吸気室と連通するときには、他方のダンパーが閉じて吸気室との連通を遮断して、集綿室及びバイパス室の室内を、風綿送風用空気が交互に通過すると共に、集綿室と吸引室との連通を遮断したときに前記回収手段を作動させる風綿処理装置において、前記回収手段の開閉操作弁と、該開閉操作弁及び前記ダンパー操作具を制御する制御器とを備え、該制御器は、前記集綿室又はそれに連通する部分の静圧を測定する負圧測定器を備え、負圧測定器の測定静圧が設定圧に到達したとき、前記回収手段による風綿回収のための動作信号を前記開閉操作弁及び前記ダンパー操作具に出力することを特徴とする風綿処理装置である。
本発明によれば、風綿送風用空気が集綿室及びバイパス室の室内を交互に通過することができ、また、集綿室又はそれに連通する部分の静圧が設定圧に到達したとき、回収手段による風綿回収のための動作信号が開閉操作弁及びダンパー操作具に出力される。
【０００６】
風綿を圧縮しながら排出すために請求項２記載の本発明が採用した手段は、前記回収室に集められた風綿を圧縮する圧縮手段と、圧縮された風綿を排出口から装置外に排出する排出手段とを備え、これら圧縮手段及び排出手段は、前記回収室にある風綿を該排出口に向かって押圧する押出具と、該押出具を駆動する駆動手段とを含んで構成され、該押出具により、前記回収室にある風綿を押圧して圧縮しつつ該排出口から排出するようにした請求項１に記載の風綿処理装置である。
本発明によれば、駆動手段で押出具を駆動することで、回収室にある風綿を圧縮しつつ排出口から装置装置外に排出できる。
【０００７】
風綿を安定よく圧縮しながら排出すために請求項３記載の本発明が採用した手段は、前記回収室及び前記押出具を筒状に形成することで、回収室の一方の端部から回収室内へ押出具を抜き差しできるようにし、前記回収室の周囲部に開口した入口を介して回収室内へ集めた風綿を回収室の他方の端部に開口した出口から押し出すようにした請求項２記載の風綿処理装置である。
本発明によれば、押圧具が抜かれた回収室に集める風綿量及び回収室へ差し込む押圧具のストローク量を一定にできるため、風綿を押圧具で安定よく圧縮しながら回収室の出口から押し出すことができる。
【０００８】
より強く圧縮した風綿を排出口から排出するために請求項４記載の本発明が採用した手段は、前記回収室と前記排出口とを連通する排出管を備え、前記押出具により、前記回収室にある風綿を該排出管に押し出すようにした請求項２又は３記載の風綿処理装置である。
本発明によれば、排出管を通過する風綿に大きな通過抵抗を生じさせることが可能となり、この大きな通過抵抗に打ち勝つ押圧具の強い押圧力で風綿を排出管へ押し出し、強く圧縮された状態の風綿を排出口から排出させることができる。
【０００９】
【発明の実施の形態】
以下、本発明に係る風綿処理装置（以下、「本発明装置」という）を図１乃至図３に示す実施の形態に基づいて説明する。図１は本発明装置の全体を示す正面図であって図２のＡ−Ａ線における断面図、図２は本発明装置の全体を示す部分断面した平面図、図３は要部の一つである押出具の近辺を拡大して示す右側断面図である。
【００１０】
本実施の形態に係る風綿処理装置１は、例えば、紡績機の機台端部に設けられ、図１及び図２に示す如く、風綿付着用フィルター２を設けた集綿室３と、集綿室３に隣接する回収室４と、集綿室３の風綿付着用フィルター２に付着している風綿Ｃを回収室４へ集める回収手段５とを備えている。風綿処理装置１は、集綿室３に隣接したバイパス室６を設け、両室３，６の入口３ａ，６ａを外部接続口１１に臨ませ、バイパス室６の入口６ａに風綿付着用フィルター１２を配置してある。集綿室３の入口３ａには、上端をヒンジ連結した揺動自在な開閉板２７が設けられている。この開閉板２７は、集綿室３が吸引状態のときには集綿室３のフイルター２に向かう吸引力により持ち上げられて入口３ａを開放し、集綿室３が吸引状態でないときには自重及び他方の入口６ａの吸引力により垂れ下がり入口３ａを閉鎖する。外部接続口１１には、設備等から集められた風綿を送風するダクト（図示略）が接続される。
【００１１】
この集綿室３及びバイパス室６の空気出口側は、吸引フアン１０で吸気される吸気室７に、ダンパー８，９を介して連通してある。ダンパー８，９は、エアーシリンダ等を用いたダンパー操作具２５で開閉操作され、一方が開いて吸気室７と連通するときには、他方が閉じて吸気室７との連通を遮断するようにしてあり、集綿室３及びバイパス室６の室内を、風綿送風用空気が交互に通過するようになっている。ダンパー８，９の開閉を自動で行うときには、風綿処理装置１に備えた制御器２６の出力信号ａを受けてダンパー操作具２５を自動操作して行う。なお、ダンパー８，９の開閉を手動で行うことも可能である。
【００１２】
上記風綿付着用フィルター２，１２は、外部接続口１１を介して導入された風綿送風用空気中に含まれている風綿を捕捉し、空気のみを通過させるようになっている。上記ダンパー８が開き且つダンパー９が閉じているときには、開閉板２７が開放状態の入口３ａ及び集綿室３内を風綿送風用空気と共に矢符Ｄ方向へ通過する風綿が風綿付着用フィルター２で捕捉され、逆に、ダンパー８が閉じ且つダンパー９が開いているときには、入口３ａの閉鎖により風綿付着用フィルター１２で風綿が捕捉されると共に捕捉後の風綿送風用空気がバイパス室６を通過することになる。風綿付着用フィルター１２で捕捉さた風綿は、ダンパーの切替えにより、集綿室３へ導かれる風綿送風用空気によりフィルター１２から剥離させられて集綿室３へ導かれ、風綿付着用フィルター２に捕捉される。
【００１３】
前記集綿室３の風綿付着用フィルター２は、若干傾斜した起立状態に配置され、集綿室内側の上方に回収手段５を併設すると共に、下方に回収室４の入口４ａを位置させてある。回収手段５は、風綿付着用フィルター２の幅全域に渡って圧縮空気を吹き下ろすように噴出する複数個の噴出口１３ａを開設した配管１３と、配管１３に圧縮空気を供給するためのコンプレッサー（図示略）と、配管１３とコンプレッサーとの間に設けた電磁弁からなる開閉操作弁２２とを備え、制御器２６の出力信号ｂを受けて開閉操作弁２２を開閉操作することにより複数個の噴出口１３ａから圧縮空気を噴出するようになっている。なお、開閉操作弁２２は、手動で開閉操作することもある。
【００１４】
上記開閉操作弁２２及び前記ダンパー操作具２５を制御する制御器２６は、集綿室３又はそれに連通する部分（例えば、風綿付着用フィルター２より上流側のダクト内）の静圧を測定する負圧測定器（図示略）とタイマーとを備え、風綿付着用フィルター２に所定厚みの風綿が付着したのに伴い負圧測定器の測定する集綿室３の静圧が弱くなって設定圧に到達したとき、回収手段５による風綿回収のための動作信号を開閉操作弁２２及びダンパー操作具２５に出力し、次に風綿回収に必要な時間を設定するタイマーの設定時間を経過したとき、再び集綿室３のフィルター２で風綿を捕捉するための復帰信号を開閉操作弁２２及びダンパー操作具２５に出力するようになっている。なお、制御器２６は、負圧測定器を備える代わりに、プログタイマーに予め設定した時間に基づいて自動的に風綿回収動作を行うようにしてもよい。
【００１５】
圧縮空気を吹き下ろす回収手段５の場合には、風綿付着用フィルター２を駆動させる必要もなく、フィルター全面に付着した風綿Ｃを回収室４へ確実に回収させることができる。なお、回収手段５は、圧縮空気を吹き下ろす形式以外に、図示は省略したが、風綿付着用フィルター２の表面に沿って掻取板を下ろして風綿を集める掻取板形式や、エンドレス状の風綿付着用フィルター２を回転駆動させて風綿を集めるフィルター駆動形式等に置換することも可能である。上記回収室４は、入口４ａに末広がりの導入部２４が接続され、回収手段５で回収される風綿を回収室内４ｄへ導きやすいようにしてある。
【００１６】
本実施の形態に係る風綿処理装置１は、回収された風綿を装置外に排出するための排出口１５（図２参照）と、回収室４にある風綿Ｃを圧縮しつつ排出口１５に押し出す圧縮排出手段である押出具１６と、押出具１６を駆動する駆動手段１７とを備えている。回収室４及び押出具１６は、図２に示す如く、円筒状に形成され、回収室４の一方の端部から回収室内へ押出具１６を抜き差しできるようになっている。押出具１６は、回収室４の周囲部に開口した入口４ａを介して回収室内へ集められた風綿Ｃを、回収室４の他方の端部に開口した出口４ｂから押し出すようになっている。駆動手段１７は、エアーシリンダー等からなり、矢符Ｅ方向へ前後移動する出力軸１７ａの先端に、筒状の押出具１６を連結してある。押出具１６の押圧面１６ａは、回収室４の内周形状と略同様の形状で、且つ、回収室４の内周部の断面積よりやや小さい面積を有しており、抜き差しできるようになっている。回収室４及び押出具１６は、回収室４の室内へ押出具１６を抜き差しできる構造にすることにより、押出具１６が抜かれたときに回収室４へ集めることができる風綿を一定量にできると共に、回収室４へ差し込む押出具１６のストロークを一定量にできるため、押圧面１６ａで風綿を安定よく圧縮しながら回収室４の出口４ｂから押し出すことができる。なお、例えば、排出口１５に開閉シャッターと、その駆動手段を設けることができ、その場合、閉鎖しているシャッターに押し付けて風綿を圧縮することも可能であり、適宜タイミングで開閉シャッターを開放することにより風綿を排出することができる。
【００１７】
本実施の形態に係る風綿処理装置１は、図１及び図３に示す如く、回収手段５で集められる風綿Ｃを回収室４に引き込む空気流を発生される吸引手段１８を備えている。この吸引手段１８は、回収室４の周囲部に開口したフィルター１９付きの吸引口４ｃと、吸引フアン２０と、吸引口４ｃと吸引フアン２０の吸引口とを連通するダクト２３とを備えている。吸引口４ｃは、上方の入口４ａと回収室４の室内４ｄを介して対峙するように下方に形成されている。吸引口４ｃに備えたフイルターは、回収室内４ｄに回収された風綿を吸引フアン２０へ吸引させないようにするためのものである。吸引フアン２０は、その排気口２０ａを前記吸気室７に連通させることにより、吸引フアン２０の吸引圧（例えば、静圧が４００〜６００ｍｍＡｑの範囲）に前記吸引フアン１０の吸引圧（例えば、静圧が２００〜４００ｍｍＡｑの範囲）を加算した吸引圧を吸引口４ｃに発生させ、風綿付着用フィルター２から回収室４の入口４ａへ落下した風綿Ｃを、回収室４の室内へ確実に吸引して回収できるようになっている。回収室４は、風綿を回収しないときには、押出具１６が差し込まれて吸引口４ｃが閉じられ、吸引フアン２０による吸引を停止する。この吸引停止により、遠心式の吸引フアン２０の駆動モータの負荷を低減できる。
【００１８】
本実施の形態に係る風綿処理装置１は、回収室４の端部に開口した出口４ｂから排出管２１を延設し、排出管２１の開口した先端を前記排出口１５（図２参照）とすることにより、回収室４にある風綿Ｃを前記押出具１６で圧縮させて塊Ｃａとなった風綿を排出管２１に向かって押し出すようにしてある。排出管２１は、その内径を適宜選択することにより、通過する風綿の塊Ｃａに大きな通過抵抗を生じさせることが可能となるため、回収室４の室内で風綿Ｃを強く押圧して排出管へ押し出させて、圧縮されて扱い易い状態の風綿の塊Ｃａとして排出口１５から排出させることができる。本実施の形態では、排出管２１内部の断面形状は、回収室４内部の断面形状と略同一であり、且つ、両方の断面積が略同一となっている。なお、風綿処理装置１は、排出管２１を設けることなく、回収室４の出口４ｂを排出口１５とすることも可能である。
【００１９】
次に、風綿処理装置１の風綿を回収する動作を説明する。先ず、風綿処理装置１は、ダンパー８が開き且つダンパー９が閉じることにより、集綿室３が吸引状態となり、開閉板２７を開放状態とした入口３ａ及び集綿室３内を風綿送風用空気と共に矢符Ｄ方向へ通過する風綿を風綿付着用フィルター２で捕捉する。風綿付着用フィルター２で捕捉した風綿が所定厚みとなり、集綿室３内のフイルター２より上流側の吸引圧が低下しときには、制御器２６から発せられる出力信号ａを受けたダンパー操作具２５の操作によりダンパー８を閉じ且つダンパー９を開いて次の風綿回収動作に移る。ダンパー操作具２５は、手動で操作されることもある。
【００２０】
風綿回収動作では、回収手段５は、制御器２６から発せられる出力信号ｂで開閉操作弁２２を開弁操作して配管１３の複数個の噴出口１３ａから風綿付着用フィルター２の幅全域に渡って圧縮空気を吹き下ろすように噴出させ、風綿付着用フィルター２に付着している風綿層を剥離させつつ下方へ吹き落とす。この吹き落としと並行して、図３に示す如く、回収室４から押出具１６を引き抜いて吸引口４ｃを開口させることで、回収室４の室内４ｄと吸引フアン２０とを連通させ、集綿室３内の空気を回収室４の入口４ａへ吸引（矢符Ｇ方向）し、集綿室３の下方へ吹き落とされている風綿Ｃを回収室４の室内４ｄへ強制的に吸引して回収する。回収室４の室内４ｄに所定量の風綿Ｃが回収されたならば、次の圧縮動作に移る。なお、風綿回収動作から圧縮動作への移行は、例えば、タイマを使って設定時間だけ回収動作が行われるように制御することもできるし、回収室４内の静圧を検出し、それに基づいて圧縮動作に移行するように制御することもできる。
【００２１】
圧縮動作では、駆動手段１７で押出具１６を前進させて回収室４の室内４ｄへ押出具１６を差し込んで、室内４ｄに回収されている風綿Ｃを圧縮する。圧縮された風綿は、塊Ｃａとなって回収室４の出口４ｂを通過して排出管２１へ押し出される。この圧縮動作は、複数回動作させてもよい。押出具１６は、排出管２１の通過抵抗に打ち勝つ強い押圧力で風綿を圧縮するので、圧縮されて扱い易い状態の風綿の塊Ｃａを形成して排出管２１の終端である排出口１５から排出させることになる。
【００２２】
前記風綿回収動作及び圧縮動作のときには、集綿室３の入口３ａの開閉板２７が閉鎖しており、風綿送風用空気はバイパス室６へ導かれ、風綿付着用フィルター１２で風綿が捕捉される。制御器２６にタイマー設定された前記風綿回収動作及び圧縮動作の時間が経過すると、ダンパー操作具２５及び開閉操作弁２２が制御器２６から出力信号を受け、ダンパー操作具２５の操作でダンパーの切替えが行われると共に開閉操作弁２２が閉じ、最初の動作である風綿付着用フィルター２による風綿捕捉の動作に移る。風綿回収動作及び圧縮動作中にフィルター１２に捕捉されて付着している風綿は、このダンパーの切替えにより集綿室３へ導かれた風綿送風用空気により、フィルター１２から剥離させられて集綿室３へ導かれ、新たに導かれた風綿と共に風綿付着用フィルター２に捕捉されることになる。
【００２３】
【発明の効果】
請求項１記載の本発明装置は、風綿送風用空気が集綿室及びバイパス室の室内を交互に通過することで、集綿室の風綿付着用フィルターによる風綿の捕捉と、バイパス室の風綿付着用フィルターによる風綿の捕捉とを交互にでき、また、集綿室又はそれに連通する部分の静圧が設定圧に到達したとき、制御器で開閉操作弁及びダンパー操作具を制御して、回収手段による風綿回収を行う。

In the case of the collecting means 5 for blowing down the compressed air, it is not necessary to drive the filter 2 for attaching fly waste, and the fly waste C adhered to the entire surface of the filter can be reliably collected in the collecting chamber 4. The collecting means 5 is not shown in the drawings except for the type of blowing down the compressed air. However, the collecting means 5 may be a scraping plate type in which the scraping plate is lowered along the surface of the filter 2 for collecting fly waste to collect fly waste, or an endless type. It is also possible to replace the filter 2 with a filter drive type or the like that collects fly wool by rotating and driving the filter 2 for attaching fly wool. The collecting chamber 4 has a divergent introduction portion 24 connected to the inlet 4a so that fly waste collected by the collecting means 5 can be easily guided to the collecting chamber 4d.

The fly waste processing apparatus 1 according to the present embodiment has a discharge port 15 (see FIG. 2) for discharging the collected fly waste to the outside of the apparatus, and a discharge port while compressing the fly waste C in the collection chamber 4. An extruder 16 is a compression / discharge unit for extruding the extruder 15 and a driving unit 17 for driving the extruder 16. As shown in FIG. 2, the recovery chamber 4 and the pushing tool 16 are formed in a cylindrical shape so that the pushing tool 16 can be inserted into and removed from one end of the collecting chamber 4 into the collecting chamber. The pusher 16 pushes the fly waste C collected into the collection chamber through the inlet 4a opened to the periphery of the collection chamber 4 from the outlet 4b opened to the other end of the collection chamber 4. . The driving means 17 is composed of an air cylinder or the like, and has a cylindrical extruder 16 connected to the tip of an output shaft 17a that moves back and forth in the direction of arrow E. The pressing surface 16a of the pushing tool 16 has substantially the same shape as the inner peripheral shape of the collecting chamber 4 and has an area slightly smaller than the cross-sectional area of the inner peripheral portion of the collecting chamber 4, so that it can be inserted and removed. ing. The collecting chamber 4 and the extruding tool 16 are structured so that the extruding tool 16 can be inserted into and removed from the chamber of the collecting chamber 4, so that the amount of fly waste that can be collected in the collecting chamber 4 when the extruding tool 16 is pulled out can be made constant. At the same time, since the stroke of the pusher 16 inserted into the collection chamber 4 can be made constant, the fly waste can be extruded from the outlet 4b of the collection chamber 4 while being stably compressed by the pressing surface 16a. In addition, for example, an opening / closing shutter and its driving means can be provided at the discharge port 15. In this case, it is also possible to press the closed shutter to compress the fly, and open / close the opening shutter at an appropriate timing. By doing so, fly waste can be discharged.
[0017]
As shown in FIGS. 1 and 3, the fly waste processing apparatus 1 according to the present embodiment includes a suction unit 18 that generates an air flow that draws the fly waste C collected by the collection unit 5 into the collection chamber 4. . The suction means 18 includes a suction port 4 c with a filter 19 opened around the collection chamber 4, a suction fan 20, and a duct 23 communicating the suction port 4 c and the suction port of the suction fan 20. . The suction port 4c is formed below so as to face the upper inlet 4a via the chamber 4d of the collection chamber 4. The filter provided in the suction port 4c is for preventing fly waste collected in the collection chamber 4d from being sucked into the suction fan 20. The suction fan 20 communicates the suction port (for example, static pressure of 400 to 600 mmAq) to the suction pressure of the suction fan 10 (for example, static pressure) by connecting the exhaust port 20 a to the suction chamber 7. A suction pressure to which the suction pressure is added to the suction port 4c is added to the suction port 4c, and the fly waste C that has fallen from the fly fouling filter 2 to the inlet 4a of the collection chamber 4 is reliably transferred into the collection chamber 4. It can be collected by suction. In the collecting chamber 4, when the fly waste is not collected, the pusher 16 is inserted, the suction port 4c is closed, and the suction by the suction fan 20 is stopped. By stopping the suction, the load on the drive motor of the centrifugal suction fan 20 can be reduced.
[0018]
In the fly waste processing apparatus 1 according to the present embodiment, the discharge pipe 21 is extended from the outlet 4b opened at the end of the collection chamber 4, and the open end of the discharge pipe 21 is connected to the discharge port 15 (see FIG. 2). By doing so, the fly waste C in the recovery chamber 4 is compressed by the pushing tool 16 and the fly waste formed into the lump Ca is pushed out toward the discharge pipe 21. By appropriately selecting the inner diameter of the discharge pipe 21, a large passage resistance can be generated in the lump Ca passing through the discharge pipe 21. It can be extruded into a pipe and discharged from the outlet 15 as a lump Ca of fluff in a compressed and easy-to-handle state. In the present embodiment, the cross-sectional shape inside the discharge pipe 21 is substantially the same as the cross-sectional shape inside the collection chamber 4, and both cross-sectional areas are substantially the same. In the fly waste processing apparatus 1, the outlet 4b of the collection chamber 4 can be used as the discharge port 15 without providing the discharge pipe 21.
[0019]
Next, the operation of the fly waste processing apparatus 1 for collecting fly waste will be described. First, when the damper 8 is opened and the damper 9 is closed, the cotton waste collection chamber 3 is in a suction state, and the fly waste processing apparatus 1 blows the cotton waste through the inlet 3a and the cotton collection chamber 3 with the opening and closing plate 27 opened. The fly waste passing in the direction of arrow D together with the working air is captured by the fly waste attaching filter 2. When the fly waste captured by the fly waste attaching filter 2 has a predetermined thickness and the suction pressure on the upstream side of the filter 2 in the cotton collecting chamber 3 decreases, the damper operating tool having received the output signal a issued from the controller 26 By the operation 25, the damper 8 is closed and the damper 9 is opened to move to the next fly waste collecting operation. The damper operation tool 25 may be manually operated.
[0020]
In the fly waste collecting operation, the collecting means 5 operates the opening / closing operation valve 22 with the output signal b issued from the controller 26 to open the entire width of the fly waste attaching filter 2 from the plurality of jet ports 13 a of the pipe 13. Compressed air is blown down so as to blow down, and blows down while removing the fly waste layer adhering to the fly waste attaching filter 2. In parallel with the blow-down, as shown in FIG. 3, by pulling out the extruding tool 16 from the collecting chamber 4 and opening the suction port 4c, the chamber 4d of the collecting chamber 4 and the suction fan 20 communicate with each other to collect cotton. The air in the chamber 3 is sucked into the inlet 4a of the collection chamber 4 (in the direction of arrow G), and the fly wool C blown down below the cotton collection chamber 3 is forcibly sucked into the room 4d of the collection chamber 4. To collect. When a predetermined amount of fly waste C is collected in the collection chamber 4d, the operation proceeds to the next compression operation. The transition from the fly waste collection operation to the compression operation can be controlled, for example, using a timer so that the collection operation is performed for a set time, or the static pressure in the collection chamber 4 is detected, and Can be controlled to shift to the compression operation.
[0021]
In the compression operation, the pushing tool 16 is advanced by the driving means 17 and the pushing tool 16 is inserted into the room 4d of the collection chamber 4 to compress the fly waste C collected in the room 4d. The compressed fly wool becomes the mass Ca and is pushed out to the discharge pipe 21 through the outlet 4b of the collection chamber 4. This compression operation may be performed a plurality of times. Since the pushing tool 16 compresses the fly waste with a strong pressing force that overcomes the passage resistance of the discharge pipe 21, the push tool 16 forms the lump Ca of the fly waste in a compressed and easy-to-handle state, and forms the discharge port 15 which is the end of the discharge pipe 21. Will be discharged from
[0022]
At the time of the fly waste collecting operation and the compressing operation, the opening / closing plate 27 at the entrance 3a of the cotton wool collecting chamber 3 is closed, the air for blowing fly waste is guided to the bypass chamber 6, and the fly waste attaching filter 12 causes the fly waste to be removed. Is captured. When the time of the fly waste collection operation and the compression operation set by the timer in the controller 26 elapses, the damper operating tool 25 and the opening / closing operation valve 22 receive an output signal from the controller 26, and the damper operating tool 25 is operated to operate the damper. The switching is performed and the opening / closing operation valve 22 is closed, and the operation shifts to the first operation of capturing the fly waste by the fly waste attaching filter 2. The fly waste trapped and attached to the filter 12 during the fly waste collecting operation and the compressing operation is separated from the filter 12 by the fly waste blowing air guided to the cotton collecting chamber 3 by switching the damper. It is led to the cotton collecting chamber 3 and is captured by the fly waste attaching filter 2 together with the newly led fly waste.
