Description

【発明が属する技術分野】
本発明は、経糸糊付け機において、糊付け前に、湿潤装置によりシート状の経糸に水分を付与する過程で、経糸の水分率を検出する手段、および経糸の水分率を検出して、経糸の水分率を目標水分率に制御する手段に関する。
【0002】
【従来の技術】
経糸糊付け機において、湿潤装置は、糊付け前に、シート状の経糸を水槽の水で湿潤(浸透)させ、経糸に水分を付与する。経糸に浸透した水分は、糊液と容易に置換され、かつ混合されるので、湿潤(水分付与)は、糊付け効果を増し、糊材を節約するのに有効である。
【0003】
湿潤装置は、シート状の経糸に対する湿潤部(湿潤ロール)と絞り部(絞りロール)とからなり、シート状の経糸は、湿潤部で水槽の水と接触し、水分を吸収した後に、絞り部で一対の絞りロールの間を通過する。絞りロールにより、経糸全体が均一に湿潤すると共に、余分な水分は、除かれ、水槽に還元される。
【0004】
水分付与の過程で、水槽の水量を測定することにより、シート状の経糸の消費水分量を測定することができ、シート状の経糸量から正確かつ容易に水分率の検出が可能となる。また、糊付着率の制御は、検出した水分率に基づき水分率を制御することにより、シート状の経糸に対する糊付着率をほぼ一定に維持する。
【0005】
【発明が解決しようとする課題】
蒸気を投入し、水槽の水を効率良く加熱して、60°C以上、一般的には、80〜90℃の温水とし、経糸に温水を付与することにより、繊維の内部まで十分に水分を浸透させることができ、これによって糊付け効果がより向上するが、投入した蒸気の一部が水槽の水に加わるので、シート状の経糸の消費水分量を正確に測定することができない。
【0006】
したがって、本発明の目的は、シート状の経糸に水分を付与した後に糊付けを行う経糸糊付け機において、経糸に温水により水分を付与し、水分の浸透性を良くすると共に、経糸の糊付け前の水分率を正確に測定できるようにし、さらに、水分率を正確に制御できるようにすることである。
【0007】
【課題を解決するための手段】
上記の目的のもとに、本発明は、水槽の水に接する位置に加熱部を設け、この加熱部の熱伝達体により、水槽の水を増すことなく加熱して所定の温度の温水とし、この温水により経糸の繊維の内部まで十分に水分を浸透させ、経糸に対する糊付け効果を上げると共に、水槽の水量から経糸の消費水分量を検出して水分率を検出し、さらに水分率を制御している。
【0008】
具体的に記載すれば、請求項1の経糸糊付け機は、水槽からの水をシート状の経糸に吸収させた後に、絞り部でシート状の経糸を絞って水分付与処理を行うと共に、水分付与処理に用いた余分な水を水槽に還元し、給水源に連なる給水路が設けられて、給水源の水が水槽に供給される湿潤装置と、水分付与後にシート状の経糸を糊付けする糊付け装置とを有する経糸糊付け機において、熱伝達体を有し該熱伝達体を介して加熱媒体と水槽の水とが接する加熱部が設けられ、加熱部により加熱され、所定の温度の温水がシート状の経糸に水分付与すると共に、前記湿潤装置での消費水分量を検出する消費水分量検出手段と、水分付与処理されたシート状の経糸量を検出する経糸量検出手段と、検出した消費水分量と経糸量とから水分付与処理による経糸の水分率を算出する水分率演算器と、を具備し、消費水分量検出手段と経糸量検出手段とは同期して検出を行うことを特徴としている。
【0009】
請求項2、7の経糸糊付け機において、水槽に高温蒸気噴出装置が設けられて水槽内の水を加熱し、遅くとも消費水分量検出の開始までには、高温蒸気の噴出を停止することを特徴とする。
【0010】
また、請求項6の経糸糊付け機は、請求項1の経糸糊付け機において、算出した前記水分率に基づいて、前記絞り部の絞り圧を制御し、前記経糸の水分率を目標水分率に制御する絞り圧制御器を具備し、消費水分量検出手段と経糸量検出手段とは同期して検出を行うことを特徴としている。
【0011】
請求項3、8の経糸糊付け機において、前記消費水分量検出手段として水位センサーが設けられ、前記水槽の水位を検出して前記消費水分量を検出することを特徴とする。
【0012】
請求項4、9の経糸糊付け機において、前記消費水分量検出手段として、前記給水路に設けられた流量計と水位センサーとを備え、供給水量と前記水槽の水位とを検出して前記消費水分量を検出することを特徴とする。
【0013】
請求項5、10の経糸糊付け機において、水槽に水位センサーと給水路の制御弁とを有する水位制御装置を設け、水槽の水位を検出し、供給する水の流量を制御することにより、水槽の水位を一定に維持することを特徴とする。
【0014】
【発明の実施の形態】
図1は、本発明の経糸糊付け機1を示す。経糸糊付け機1は、シート状の経糸2に対する糊付けのために、湿潤装置3、糊付け装置4および糊付け乾燥装置5を具備する。
【0015】
湿潤装置3は、経糸2に水分を付与するために、水分付与用の水槽8の内で、水すなわち温水7を収容している。水分付与用の水槽8に高温蒸気源に連なる高温蒸気噴出装置63が設けられ、機械の稼働前に、高温蒸気を噴出させて水槽8の水を加熱する。高温蒸気は、水槽8の水と接して直接加熱すると共に、高温蒸気の一部は、水槽8の水に高温の温水として加わり、効率よく加熱する。
【0016】
なお、高温蒸気噴出装置63は、高温蒸気の噴出を稼働後も継続してよいが、遅くとも消費水分量検出の開始までには、噴出を停止する。また、高温蒸気は、消費水分量検出を中断している期間も噴出してもよく、遅くとも消費水分量検出を再開するまでには、噴出を停止する。これにより、消費水分量検出期間に高温蒸気が水槽8の水に加わって、消費水分量検出が不正確となることがない。
【0017】
湿潤装置3は、シート状の経糸2を60°C以上好ましくは80〜90°C程度の温度の水すなわち温水7に浸して、経糸2に水分を付与するために、水分付与用の水槽8の内で、温水7に浸っている湿潤ロール9、および温水7による経糸2に対する水分付与後に、経糸2から余分な水分を絞り取るために、絞り部10を有している。シート状の経糸2は、案内ロール11に案内されて、湿潤ロール9に接して、水槽8の内で、温水7に浸った後、絞り部10を通過する。水槽32に供給される温水7は、給水源6としての温水タンクの冷水に高温蒸気を噴出して加熱したり、電気ヒータにより加熱したりして得られる。
【0018】
温水7は、温水タンクなどの給水源6から給水路19により、給水路19中の流量計20および制御弁21を経て、水位検出用の水槽32の内部に供給される。温水7の供給は、制御弁21の開閉により制御され、その間の温水7の供給水量は、消費水分量検出手段として流量計20により計測される。なお、制御弁21は、電磁開閉弁または電動流量調整弁により構成され、それらの弁の開閉または弁の開度調整により供給水量を調節する。
【0019】
水分付与用の水槽8の内部で、温水7の水位は、オーバーフロー堰22によって水位検出用の水槽32に流出する。水槽32内の温水7の水位は、消費水分量検出手段としての水位センサー33により検出される。水槽32内の温水7は、還流パイプ34、フイルター35、ポンプ36および加熱部55を経て、水槽8の内部に還流することにより還元される。
【0020】
このようにして、水槽8内で温水7の水位は、水位検出用の水槽32からの還流とオーバーフローとによって、給水源6からの給水量や水分付与処理による消費水量と関係なく、一定に維持される。また、加熱部55は、温水7に接して、温水7を適切な熱量により加熱し、その温度を80〜90°C程度の目標温度に維持する。
【0021】
絞り部10は、例えば一対の絞りロール12および絞り力調節手段13からなる。一対の絞りロール12のうち、下方の絞りロール12は、水槽8内で、80〜90°C程度の温水7に浸っており、上方の絞りロール12は、絞り力調節手段13として、例えば加圧レバー14の先端に支持され、流体圧シリンダ15の絞り力によって、下方の絞りロール12に対して所定の絞り圧により接し、経糸2から過剰な水分を絞り取る。このとき、経糸2の水分は、絞り圧により、シート状の経糸2に対して全体に均一な付着となると共に、経糸2の繊維の内部まで深く浸透する。このようにして、湿潤装置3は、シート状の経糸2に対して、水分付与処理(湿潤処理)を行う。
【0022】
シート状の経糸2に対する水分付与量は、一対の絞りロール12の間の絞り圧を高めれば、減少し、逆に、一対の絞りロール12の間の絞り圧を低くすれば、増加する。経糸2の大部分の過剰水分は、一対の絞りロール12および絞り力調節手段13により除去される。なお、加圧レバー14および流体圧シリンダ15は、それぞれ支持軸16、17により、機台などに対して定位置で回動自在に支持され、ピン18により連結されている。
【0023】
絞り部10による水分絞り工程での水分量の調整後に、シート状の経糸2は、案内ロール23に案内されて、公知の糊付け装置4に入る。糊付け装置4は、シート状の経糸2に糊付けを行うために、一対の糊付けロール24および一対の絞りロール25を有している。一対の糊付けロール24は、シート状の経糸2を挟んだ状態で、糊液槽26の内部の糊液27に浸り、シート状の経糸2に糊付けを行う。経糸2に浸透した水分は、糊付け工程で、糊液27と置換され、かつ混合される。この置換および混合のため、糊液27は、経糸2の内部まで均一に浸透する。また、一対の絞りロール25は、それらの間で糊付け後のシート状の経糸2を挟み込み、経糸2から余分な糊液27を絞り取る。
【0024】
糊付け後に、シート状の経糸2は、糊付け乾燥装置5に送り込まれる。糊付け乾燥装置5は、糊付け後にシート状の経糸2を乾燥させるために、複数の乾燥シリンダ28や案内ロール29を有している。糊付け後にシート状の経糸2は、これらの乾燥シリンダ28の表面に接することにより、加熱され、乾燥された後、案内ロール29、糸さばきバー30、巻き取りガイドロール52を経て、巻き取りビーム31に巻き取られていく。
【0025】
つぎに、図2は、水分付与用の水槽8、水位検出用の水槽32に対する水位制御装置37および温水7の加熱部55の構成を示している。湿潤装置3での水分付与処理により、温水7が消費されると、水槽32の水位が低下する。水槽32の水位が下限レベルに達したとき、水位センサー33は、そのときの水量として下限レベルの水位を検知し、水量制御器38に下限信号を出力する。ここで、水量制御器38は、補給信号(供給信号または供給増大信号)を制御弁21に送って、その弁を開くか開度を大きくして、給水源6から給水路19を介して温水7を水槽32に補給する。
【0026】
水槽32内の温水7は、還流パイプ34とポンプ36との作用により、水槽8に供給される。このため、水槽8内の温水7は、オーバーフローして水槽32に戻されて一定の水量に維持される。絞り部10から水槽8に還元途中の水量は、絞り圧により僅かに変化するものの、ほぼ一定であり、湿潤装置3の水量の増加は、水槽8、32の水量の増加となる。このように、水槽8の水量は一定に維持されるので、湿潤装置3の水量の増加は、水槽32の水量の増加となり、水槽32での水位を増加させる。
【0027】
水槽32の水位が上限レベルに達したら、水位センサー33は、それを検知して、水量制御器38に上限信号を出力するため、水量制御器38は、温水7の供給に対する停止信号(供給停止信号または供給減少信号)を電制御弁21に出力し、その弁を閉じるか開度を小さくして、温水7の供給を停止させるか、または供給を減少させる。
【0028】
一方、加熱部55は、熱伝達体として熱交換器56を有しており、この熱交換器56は、例えば還流パイプ34の途中に設けられ、循環式の細管59から加熱媒体として加熱蒸気57を取り込んで、細管59により温水7に接し、温水7の温度を80〜90°C程度の好ましい温度とする。加熱媒体として加熱蒸気57は、高温蒸気源58から循環式の細管59、電磁開閉弁60により熱交換器56に送られる。水槽8の内で、温水7の温度は、水温計61により検出され、温度制御回路62は、水温計61により検出された温度により、電磁開閉弁60の開閉または開度を制御することによって、温水7を80〜90°C程度の目標温度に維持する。なお、加熱媒体は、電熱、その他の熱でもよく、熱伝導体は、それらの熱源によって電熱ヒータなどとなる。
【0029】
このようしに、温水7は、熱交換器56により加熱されて、60°C以上の温水となり、水分付与処理の過程で、経糸2の繊維の内部まで充分に浸透する。この充分な浸透作用によって、その後の糊付け過程で、糊付け効果を上げることができる。しかも、加熱蒸気57は、加熱時に、水槽8、32の温水7に入り込まず、水槽8、32の水量を増加させることもない。このため、経糸2に対する水分付与処理の過程で、後述の図3で記載するように、消費水分量は、補給水量つまり流量計20の流量計測値から検出できる。
【0030】
図3は、水分率検出装置51および水分率制御装置40の構成を示している。この水分率検出装置51は、水分付与後の経糸2の水分率を検出するために、消費水分量検出手段としての流量計20、経糸量検出手段としての測長カウンタ39、設定器42、巻き取りガイドロール52、パルス発生器53、水分率演算器41および検出制御器54を備える。
【0031】
水分率検出装置51は、経糸量の検出と同期して消費水分量を検出して、検出される経糸量および消費水分量のいずれか一方、例えば経糸量の検出値が予め設定された所定量となった時の消費水分量を検出し、検出した消費水分量と所定量である経糸量とから、経糸2の水分率を演算する。この例では、所定量の経糸量を検出するために、所定長さの経糸2を検出しており、経糸本数と綿番手やデニール等の経糸2の単位長さ当たりの重量とから、所定長さの経糸2は、重量に換算され、所定量の経糸量となる。
【0032】
巻取りガイドロール52の回転軸には、分周プレートが取り付けられており、この分周プレートと機台に取り付けられている近接スイッチとでパルス発生器53を構成している。なお、パルス発生器53の代わりにエンコーダ等を設けてもよい。
【0033】
図3の水分率検出装置51において、巻き取りガイドロール52の回転に伴いパスル発生器53は、パルス信号を発生し、このパルス信号は、経糸量検出手段としての測長カウンタ39に入力され積算される。検出制御器54が図示しない主制御装置からの指令により、測長カウンタ39と消費水分量検出手段としての流量計20とに、同時に検出開始の信号を出力する。測長カウンタ39には、設定器42により所定量の経糸長さに対応するカウント数が予め設定されており、パルス発生器53からの積算パルス数が設定されたカウント数に達すると、測長カウンタ39は、検出終了の信号を流量計20に出力する。
【0034】
水分付与処理に用いられた水槽の温水7のうち、経糸2に付与された温水7以外の余分な温水7は、すべて湿潤装置3の水槽8に還元(還流)されるので、湿潤装置3の消費水分量は、経糸2に付与された水分量と一致する。また、この例では、所定量の経糸長さは充分な長さに設定されているので、検出の開始から終了までに、水位制御装置37は、制御弁21を複数回開閉させ、水槽32に温水7の供給を複数回にわたって行い、水位を一定に維持している。よって、流量計20により検出される水槽32への供給水量は、消費水分量にほぼ一致し、消費水分量とみなすことができると共に、経糸2への付与水分量とすることができる。
【0035】
流量計20は、計測を終了し、検出した水槽32への供給水量を、消費水分量として水分率演算器41に出力する。水分率演算器41は、検出した消費水分量を重量に換算して付与水分量とし、これを所定量の経糸量で除算して、水分率を算出し、算出した水分率を水分率検出装置40の比較器43に出力する。
【0036】
なお、水槽32への温水7の供給は、供給終了水位(上限レベル)と供給開始水位(下限レベル)の水位差をできるだけ小さくし、少量ずつ供給すれば、供給水量に基づく流量計20による消費水分量の検出は、より正確になる。
【0037】
また、水位センサー33により、検出開始時と終了時との水槽8の水位差を検出し、流量計20の検出値を補正すれば、温水7の供給を複数回行っても1回のみでも、どちらでも正確に消費水分量を検出することができる。
【0038】
さらに、図4の水分率検出装置51は、消費水分量の検出と同期して経糸量を検出して、消費水分量の検出値が設定器47により予め設定された所定量となった時の経糸量を測長カウンタ39により検出し、検出した経糸量と所定量である消費水分量とから、水分率演算器41により下記の式から経糸2の水分率を演算する。
【0039】
水分率は、下記の式により、正確に検出できる。
消費水分量(重量)=検出開始時の水槽水量−検出終了時の水槽水量+補給水量水分率(%)=100×消費水分量/シート状の経糸量
【0040】
図3にもどって、水分率制御装置40は、水分率検出装置51により求められた水分率に基づいて、経糸2の水分率の制御を実行するために、比較器43、設定器44、絞り圧制御器45および流体圧シリンダ15により構成されている。まず、比較器43は、算出した水分率と、設定器44により予め設定されている目標水分率と比較し、目標水分率について許容範囲外の偏差があるとき、絞り圧修正値の信号を絞り圧制御器45に出力する。なお、目標水分率(適正水分率)は、糸種、経糸の太さ、糊濃度、糊材、目標糊付着率などの稼働条件により異なる。
【0041】
絞り圧制御器45は、絞り圧修正値と現在の絞り圧とから、要求絞り圧を演算し、演算した要求絞り圧により流体圧シリンダ15を駆動して、一対の絞りロール12の間で適切な絞り圧を調節して行く。
【0042】
【発明の効果】
請求項1によれば、経糸糊付け機において、水槽の温水をシート状の経糸に吸収させた後に、絞り部でシート状の経糸を絞って水分付与処理を行うと共に、水分付与処理に用いた余分な温水を水槽に還元する過程で、経糸量と消費水分量を同期して検出すると共に、検出した経糸量および消費水分量から、水分付与処理による経糸の水分率を算出する。このように、消費水分量から付与水分量を直接検出するため、シート状の経糸の水分率が正確に検出できる。しかも、加熱部により加熱された所定の温度の温水がシート状の経糸に水分付与するから、水分は経糸の繊維の内部まで十分に浸透する。よって、経糸は、均一に水分付与され、糊付け装置にて糊液と置換され、かつ混合され、繊維の内部まで均一に糊付けされる。特に、糸種が綿の場合、経糸の表面に天然ロウ成分(綿ロウ)が付着しており、これが糊付着の妨げになるが、綿ロウが温水により溶融し、経糸から離脱するので、良好な糊付を行うことができる。さらに、高温蒸気や電気などの加熱媒体が熱伝達体を介して水槽の水に接するので、熱伝達体を介して加熱媒体から熱が伝達され、水槽の水が最適な温度に加熱される。よって、加熱媒体が水槽の水に加わり水量が増加することはない。このため、消費水分量は、水槽の水量から検出でき、水分率は、正確に検出できる。
【0043】
請求項2では、水槽に高温蒸気噴出装置が設けられて水槽の水を加熱し、遅くとも消費水分量検出の開始までには、高温蒸気の噴出を停止するので、高温蒸気が水槽の水に接して直接加熱し、かつ一部は水槽の水に高温の温水として加わり効率よく加熱することができると共に、消費水分量検出期間に高温蒸気が水槽の水に加わって、消費水分量検出が不正確となることがない。
【0044】
請求項3では、消費水分量検出手段として、水位センサーが設けられ、水槽の水位を検出するので、検出した水位から容易に消費水分量を検出することができる。
【0045】
請求項4では、消費水分量検出手段として、流量計と水位センサーとが設けられ、供給水量と水槽の水位とを検出するので、検出した供給水量と水位とから容易に消費水分量を検出することができる。
【0046】
請求項5では、水槽の水位センサーと給水路の制御弁とを有する水位制御装置を設け、水槽の水位を検出し、供給水の流量を制御することにより、水槽の水位を一定に維持するから、水槽の水位を一定に維持でき、消費水分量は、供給水量と同一になり、検出が容易となる。
【0047】
請求項6では、請求項1と同様の効果のほかに、算出した前記水分率に基づいて、前記絞り部の絞り圧を制御し、前記シート状の経糸を目標水分率に制御するから、その後の糊付け装置で、経糸に対する糊付着率を一定に維持することができる。
【0048】
請求項7では、高温蒸気噴出装置が設けられて水槽の水を加熱し、遅くとも消費水分量検出の開始までには、高温蒸気の噴出を停止するので、高温蒸気が水槽の水に接して直接加熱し、かつ一部は水槽の水に高温の温水として加わり効率よく加熱することができると共に、消費水分量検出期間に高温蒸気が水槽の水に加わって、消費水分量検出が不正確となることがない。
【0049】
請求項8では、消費水分量検出手段として、水位センサーが設けられ、水槽の水位を検出するので、検出した水位から容易に消費水分量を検出することができる。
【0050】
請求項9では、消費水分量検出手段として、流量計と水位センサーとが設けられ、供給水量と水槽の水位とを検出するので、検出した供給水量と水位とから容易に消費水分量を検出することができる。
【0051】
請求項10では、水槽の水位センサーと給水路の制御弁とを有する水位制御装置を設け、水槽の水位を検出し、供給水の流量を制御することにより、水槽の水位を一定に維持するから、水槽の水位を一定に維持でき、消費水分量は、供給水量と同一になり、検出が容易となる。

[0002]
[Prior art]
In a warp gluing machine, a wetting device wets (penetrates) a sheet-like warp with water in a water tank and applies moisture to the warp before gluing. Since the water that has penetrated into the warp is easily replaced and mixed with the size liquid, wetting (moistening) is effective in increasing the size effect and saving the size material.
[0003]
The wetting device includes a wet portion (wet roll) and a squeezing portion (squeezing roll) for a sheet-like warp. The sheet-like warp comes into contact with the water in the water tank at the wet portion and absorbs the water. To pass between a pair of squeezing rolls. The squeezing roll uniformly wets the entire warp, removes excess water, and returns to the water tank.
[0004]
By measuring the amount of water in the water tank in the process of imparting water, the amount of water consumed by the sheet-like warp can be measured, and the moisture content can be accurately and easily detected from the amount of sheet-like warp. The glue adhesion rate is controlled based on the detected moisture content, so that the glue adhesion rate for the sheet-like warp is maintained substantially constant.
[0005]
[Problems to be solved by the invention]
By introducing steam, the water in the water tank is efficiently heated and heated to 60 ° C. or higher, generally 80 to 90 ° C., and by applying warm water to the warp, sufficient water is introduced into the fiber. It is possible to allow the water to penetrate, thereby improving the gluing effect. However, since a part of the injected steam is added to the water in the water tank, the amount of water consumed by the sheet-like warp cannot be accurately measured.

BEST MODE FOR CARRYING OUT THE INVENTION
FIG. 1 shows a warp sizing machine 1 of the present invention. The warp sizing machine 1 includes a wetting device 3, a sizing device 4, and a sizing / drying device 5 for sizing the sheet-shaped warp 2.
[0015]
The wetting device 3 contains water, that is, warm water 7, in a water tank 8 for applying water, in order to apply water to the warp yarn 2. A high-temperature steam jetting device 63 connected to a high-temperature steam source is provided in the water tank 8 for imparting moisture, and the high-temperature steam is jetted to heat the water in the water tank 8 before the operation of the machine. The high-temperature steam is directly heated in contact with the water in the water tank 8, and a part of the high-temperature steam is added to the water in the water tank 8 as high-temperature hot water to heat efficiently.
[0016]
The high-temperature steam jetting device 63 may continue the jetting of the high-temperature steam even after the operation, but stops the jetting at the latest by the start of the detection of the consumed water amount. The high-temperature steam may also be ejected during the period in which the detection of the consumed water amount is interrupted, and the ejection is stopped at the latest until the detection of the consumed water amount is restarted. Thereby, the high-temperature steam is not added to the water in the water tank 8 during the detection period of the consumed water amount, and the detection of the consumed water amount does not become inaccurate.
[0017]
The wetting device 3 is provided with a water tank 8 for immersing the sheet-like warp 2 in water having a temperature of 60 ° C. or higher, preferably about 80 to 90 ° C., that is, hot water 7 to add water to the warp 2. Among them, a squeezing section 10 is provided to squeeze excess moisture from the warp 2 after the moist roll 9 immersed in the hot water 7 and the warm water 7 apply moisture to the warp 2. The sheet-like warp 2 is guided by the guide roll 11, comes into contact with the wet roll 9, is immersed in the hot water 7 in the water tank 8, and then passes through the squeezing section 10. The hot water 7 supplied to the water tank 32 is obtained by jetting high-temperature steam into cold water in a hot water tank as the water supply source 6 and heating the same, or by heating with an electric heater.
[0018]
The hot water 7 is supplied from a water supply source 6 such as a hot water tank via a water supply passage 19 to a water level detection water tank 32 via a flow meter 20 and a control valve 21 in the water supply passage 19. The supply of the hot water 7 is controlled by opening and closing the control valve 21, and the supply amount of the hot water 7 during that time is measured by the flow meter 20 as a consumed water amount detecting means. The control valve 21 is constituted by an electromagnetic on-off valve or an electric flow rate adjusting valve, and adjusts the amount of supplied water by opening or closing these valves or adjusting the opening of the valves.
[0019]
The water level of the warm water 7 flows into the water tank 32 for detecting the water level by the overflow weir 22 inside the water tank 8 for providing water. The water level of the warm water 7 in the water tank 32 is detected by a water level sensor 33 as a consumed water amount detecting means. The hot water 7 in the water tank 32 is reduced by returning to the inside of the water tank 8 via the reflux pipe 34, the filter 35, the pump 36, and the heating unit 55.
[0020]
In this way, the water level of the hot water 7 in the water tank 8 is kept constant by the reflux and overflow from the water tank 32 for detecting the water level, irrespective of the amount of water supplied from the water supply source 6 and the amount of water consumed by the water supply process. Is done. The heating unit 55 contacts the hot water 7 and heats the hot water 7 with an appropriate amount of heat, and maintains the temperature at the target temperature of about 80 to 90 ° C.
[0021]
The squeezing section 10 includes, for example, a pair of squeezing rolls 12 and squeezing force adjusting means 13. Of the pair of squeezing rolls 12, the lower squeezing roll 12 is immersed in hot water 7 of about 80 to 90 ° C. in the water tank 8, and the upper squeezing roll 12 is used as It is supported by the tip of the pressure lever 14 and contacts the lower squeezing roll 12 with a predetermined squeezing pressure by the squeezing force of the fluid pressure cylinder 15 to squeeze out excess moisture from the warp yarn 2. At this time, the water of the warp 2 is uniformly adhered to the sheet-like warp 2 by the drawing pressure, and penetrates deeply into the fiber of the warp 2. In this way, the wetting device 3 performs a moisture imparting process (wetting process) on the sheet-like warp yarn 2.
[0022]
The amount of water applied to the sheet-like warp 2 decreases when the drawing pressure between the pair of drawing rolls 12 is increased, and conversely, increases when the drawing pressure between the pair of drawing rolls 12 is reduced. Most of the excess moisture of the warp yarn 2 is removed by the pair of squeezing rolls 12 and the squeezing force adjusting means 13. The pressure lever 14 and the fluid pressure cylinder 15 are rotatably supported at fixed positions on a machine base or the like by support shafts 16 and 17, respectively, and are connected by pins 18.
[0023]
After the adjustment of the water content in the water squeezing step by the squeezing section 10, the sheet-like warp yarn 2 is guided by the guide rolls 23 and enters the known gluing device 4. The gluing device 4 has a pair of gluing rolls 24 and a pair of squeezing rolls 25 for gluing the sheet-like warp yarns 2. The pair of sizing rolls 24 are immersed in the sizing liquid 27 inside the sizing liquid tank 26 with the sheet-like warp 2 sandwiched therebetween, and paste the sheet-like warp 2. The water that has penetrated into the warp yarns 2 is replaced and mixed with the size liquid 27 in the size setting step. Due to this replacement and mixing, the size liquid 27 uniformly penetrates into the warp yarn 2. Further, the pair of squeezing rolls 25 sandwich the sheet-like warp 2 after gluing between them, and squeeze out excess glue liquid 27 from the warp 2.
[0024]
After gluing, the sheet-like warp yarn 2 is sent to the glue drying device 5. The glue drying device 5 has a plurality of drying cylinders 28 and guide rolls 29 for drying the sheet-like warp yarn 2 after gluing. After gluing, the sheet-like warp yarns 2 are heated and dried by contacting the surfaces of the drying cylinders 28, and then are passed through the guide roll 29, the yarn separating bar 30, the winding guide roll 52, and the winding beam 31. It is wound up.
[0025]
Next, FIG. 2 shows the configuration of the water tank 8 for imparting moisture, the water level control device 37 for the water tank 32 for detecting the water level, and the heating unit 55 of the hot water 7. When the warm water 7 is consumed by the moisture provision process in the wetting device 3, the water level in the water tank 32 decreases. When the water level in the water tank 32 reaches the lower limit level, the water level sensor 33 detects the lower limit level water level as the amount of water at that time, and outputs a lower limit signal to the water amount controller 38. Here, the water amount controller 38 sends a replenishment signal (supply signal or supply increase signal) to the control valve 21, and opens or increases the opening of the valve, so that the hot water is supplied from the water supply source 6 through the water supply passage 19. 7 is supplied to the water tank 32.
[0026]
The hot water 7 in the water tank 32 is supplied to the water tank 8 by the action of the reflux pipe 34 and the pump 36. For this reason, the warm water 7 in the water tank 8 overflows and is returned to the water tank 32, and is maintained at a constant water amount. The amount of water being reduced from the squeezing section 10 to the water tank 8 slightly changes depending on the squeezing pressure, but is substantially constant. The increase in the amount of water in the wetting device 3 results in an increase in the amount of water in the water tanks 8 and 32. As described above, since the amount of water in the water tank 8 is kept constant, an increase in the amount of water in the wetting device 3 results in an increase in the amount of water in the water tank 32, and an increase in the water level in the water tank 32.
[0027]
When the water level in the water tank 32 reaches the upper limit level, the water level sensor 33 detects this and outputs an upper limit signal to the water amount controller 38. Therefore, the water amount controller 38 outputs a stop signal (supply stop) for the supply of the hot water 7. A signal or a supply decrease signal) is output to the electronic control valve 21, and the valve is closed or the opening degree is reduced to stop the supply of the hot water 7 or reduce the supply.
[0028]
On the other hand, the heating unit 55 has a heat exchanger 56 as a heat transfer body. The heat exchanger 56 is provided, for example, in the middle of the reflux pipe 34, and flows through a circulating thin tube 59 through a heating steam 57 as a heating medium. Is brought into contact with the hot water 7 through the thin tube 59, and the temperature of the hot water 7 is set to a preferable temperature of about 80 to 90 ° C. Heated steam 57 as a heating medium is sent from a high-temperature steam source 58 to a heat exchanger 56 by a circulating thin tube 59 and an electromagnetic switching valve 60. In the water tank 8, the temperature of the hot water 7 is detected by a water thermometer 61, and the temperature control circuit 62 controls the opening and closing or the opening degree of the electromagnetic on-off valve 60 based on the temperature detected by the water thermometer 61. The hot water 7 is maintained at a target temperature of about 80 to 90 ° C. The heating medium may be electric heat or other heat, and the heat conductor may be an electric heater or the like depending on the heat source.
[0029]
In this way, the warm water 7 is heated by the heat exchanger 56 to become warm water of 60 ° C. or higher, and sufficiently penetrates into the fibers of the warp 2 during the process of imparting moisture. By this sufficient penetrating action, the gluing effect can be increased in the subsequent gluing process. In addition, the heating steam 57 does not enter the hot water 7 in the water tanks 8 and 32 during heating, and does not increase the amount of water in the water tanks 8 and 32. For this reason, in the course of the process of imparting water to the warp yarn 2, the amount of consumed water can be detected from the amount of makeup water, that is, the flow measurement value of the flow meter 20, as described in FIG.
[0030]
FIG. 3 shows a configuration of the moisture content detection device 51 and the moisture content control device 40. The moisture content detecting device 51 includes a flow meter 20 as a consumed moisture amount detecting means, a length measuring counter 39 as a warp amount detecting means, a setting device 42, a winding device, in order to detect the moisture content of the warp yarn 2 after the application of moisture. A take-up guide roll 52, a pulse generator 53, a moisture content calculator 41, and a detection controller 54 are provided.
[0031]
The moisture percentage detecting device 51 detects the amount of water consumed in synchronization with the detection of the amount of warp, and detects one of the detected amount of warp and the amount of consumed water, for example, the detected value of the amount of warp is a predetermined amount. Then, the amount of consumed water at the time of is detected, and the moisture content of the warp yarn 2 is calculated from the detected amount of consumed water and the predetermined amount of the warp yarn. In this example, in order to detect a predetermined amount of warp, a predetermined length of warp 2 is detected, and a predetermined length is determined from the number of warp yarns and the weight per unit length of the warp 2 such as cotton count and denier. The warp 2 is converted into a weight and has a predetermined warp amount.
[0032]
A frequency dividing plate is attached to the rotating shaft of the winding guide roll 52, and a pulse generator 53 is constituted by the frequency dividing plate and a proximity switch attached to the machine base. Note that an encoder or the like may be provided instead of the pulse generator 53.
[0033]
In the moisture content detecting device 51 shown in FIG. 3, the pulse generator 53 generates a pulse signal with the rotation of the winding guide roll 52, and this pulse signal is input to the length measuring counter 39 as the warp amount detecting means and integrated. Is done. The detection controller 54 simultaneously outputs a detection start signal to the length measuring counter 39 and the flow meter 20 as a consumed water amount detecting means in response to a command from a main controller (not shown). In the length measurement counter 39, a count number corresponding to a predetermined amount of warp length is set in advance by the setting device 42, and when the number of accumulated pulses from the pulse generator 53 reaches the set count number, the length measurement is performed. The counter 39 outputs a detection end signal to the flow meter 20.
[0034]
Of the hot water 7 in the water tank used for the water imparting process, any excess hot water 7 other than the hot water 7 applied to the warp yarns 2 is reduced (refluxed) to the water tank 8 of the wetting device 3. The amount of consumed water matches the amount of water given to the warp yarn 2. Also, in this example, the predetermined amount of warp length is set to a sufficient length, so that from the start to the end of detection, the water level control device 37 opens and closes the control valve 21 a plurality of times, and The hot water 7 is supplied a plurality of times to keep the water level constant. Therefore, the amount of water supplied to the water tank 32 detected by the flow meter 20 substantially matches the amount of water consumed, can be regarded as the amount of water consumed, and can be the amount of water added to the warp yarn 2.
[0035]
The flow meter 20 terminates the measurement and outputs the detected amount of water supplied to the water tank 32 to the moisture content calculator 41 as the amount of consumed water. The moisture content calculator 41 calculates the moisture content by converting the detected moisture content into a weight to give the moisture content, and divides this by a predetermined amount of warp to calculate the moisture content. The signal is output to a comparator 43 of the forty.
[0036]
The supply of the hot water 7 to the water tank 32 is performed by minimizing the difference in water level between the supply end water level (upper limit level) and the supply start water level (lower limit level), and supplying the hot water 7 little by little. The detection of the water content becomes more accurate.
[0037]
In addition, if the water level sensor 33 detects a water level difference in the water tank 8 between the start and end of the detection, and corrects the detection value of the flow meter 20, even if the supply of the hot water 7 is performed plural times or only once, In either case, the amount of consumed water can be accurately detected.
[0038]
Further, the moisture content detecting device 51 in FIG. 4 detects the warp yarn amount in synchronization with the detection of the consumed water amount, and performs the operation when the detected value of the consumed water amount becomes the predetermined amount set in advance by the setting device 47. The amount of warp is detected by the length measuring counter 39, and the water content of the warp 2 is calculated by the water content calculator 41 from the following formula based on the detected amount of warp and the predetermined amount of consumed water.
[0039]
The moisture content can be accurately detected by the following equation.
Water consumption (weight) = water tank water at the start of detection−water tank water at the end of detection + replenishment water water content (%) = 100 × water consumption / sheet warp amount
Returning to FIG. 3, the moisture content control device 40 performs the control of the moisture content of the warp yarn 2 on the basis of the moisture content obtained by the moisture content detection device 51, in order to execute the control of the comparator 43, the setting device 44, and the squeezing device. It is constituted by a pressure controller 45 and a hydraulic cylinder 15. First, the comparator 43 compares the calculated moisture percentage with a target moisture percentage preset by the setting unit 44, and when there is a deviation of the target moisture percentage out of an allowable range, reduces the signal of the throttle pressure correction value. Output to the pressure controller 45. Note that the target moisture content (appropriate moisture content) varies depending on operating conditions such as the thread type, warp thickness, paste density, paste material, and target paste adhesion rate.
[0041]
The throttle pressure controller 45 calculates a required throttle pressure from the throttle pressure correction value and the current throttle pressure, drives the fluid pressure cylinder 15 with the calculated required throttle pressure, and appropriately operates between the pair of throttle rolls 12. And adjust the iris pressure.
[0042]
【The invention's effect】
According to claim 1, in the warp sizing machine, after the hot water in the water tank is absorbed by the sheet-like warp, the sheet-like warp is squeezed by the squeezing section to perform the water-supplying process, and the excess used in the water-supplying process is used. In the process of returning the warm water to the water tank, the amount of warp and the amount of consumed water are detected in synchronization with each other, and the moisture content of the warp by the water supply process is calculated from the detected amount of warp and the amount of consumed water. As described above, since the applied water amount is directly detected from the consumed water amount, the water content of the sheet-like warp can be accurately detected. In addition, since the warm water at a predetermined temperature heated by the heating unit imparts water to the sheet-like warp, the water sufficiently penetrates into the fibers of the warp. Therefore, the warp yarn is uniformly water-moistened, replaced with the size liquid by the sizer, mixed, and uniformly glued to the inside of the fiber. In particular, when the yarn type is cotton, a natural wax component (cotton wax) adheres to the surface of the warp, which hinders glue adhesion. However, since the cotton wax is melted by warm water and detached from the warp, it is good. Gluing can be performed. Further, since a heating medium such as high-temperature steam or electricity contacts the water in the water tank via the heat transfer element, heat is transferred from the heating medium via the heat transfer element, and the water in the water tank is heated to an optimum temperature. Therefore, the heating medium is not added to the water in the water tank, and the amount of water does not increase.
