507039 五、發明說明（1 ) 發明之領域 本發明係關於一種在欲上漿之經紗預先濕潤後進行上漿 之上漿機中，使上漿裝置之上漿液濃度控制在管理値之方 法。 先前技術說明 習知上，經紗在進行上漿時，使此經紗預先濕潤後再進行 上漿的話，除會增加上漿效果外，並且可達到節省上漿材之 目的。一般習知上，經紗在通過80°C〜90°C之熱水後，乾燥 到一定之水分後再進行上漿的話，比較具有效果。 另一方面，預先濕潤後的經紗通過上漿裝置時，上漿裝置 之上漿液被濕潤後的經紗所釋出的水分所稀釋。因而，爲 了維持經紗上適當的上漿，必須使上漿裝置之上漿液濃度 被管制在目標値。 因此，預定準備較上漿裝置之上漿液濃度高的高濃度上 漿液，當上漿裝置因被濕潤後的經紗所檢取部分上漿液而 欲補給時，使用此高濃度之上漿液，而可達成上漿裝置之上 漿液濃度管理。 但是，補給用上漿液之濃度，若沒有與經紗之水分檢取率 、或者上漿前經紗之水分率、或濕潤後經紗之上漿液的檢 取率正確對應的話，繼續補給一定濃度之上漿液時，上漿裝 置之上漿液濃度會漸漸地從管理値產生偏離，因而產生無 法正確的對經紗上漿之情形。 因此，習知之上漿機中，因該上漿裝置之上漿液濃度必須 507039 五、發明說明（2) 經常調整在管理値中，故會裝置濃度計，當要進行上漿液補 給時，可用來計算測量上漿裝置的上漿液濃度，必須對應所 得之値，調整所欲補給的上漿液濃度。實際上，準備高濃度 及低濃度之二種上漿液與水，於補給之時將這些上漿液與 水對應於前述測定値依比例混合，用以調整上漿液濃度。 但是，爲了修正濕潤後經紗上已被稀釋之上漿裝置之上 漿液濃度，上漿液與水之混合、補給上漿液之上漿液濃度 須一個個調整之外，處理及手續上更是煩雜，因而無法自動 地控制在管理値。 因而，希望能開發出保持使用一定濃度之補給上漿液之 下，使上漿裝置之上漿液濃度可被控制在預定之目標値之 方法。 發明之扼要說明 依照本發明之主要方面，在具有濕潤裝置及上漿裝置而 預先使經紗濕潤後進行上漿之上漿機中，本發明之上漿裝 置之上漿液濃度之控制方法，其特徵爲：該上漿裝置之上漿 液濃度可被檢出或推定，當上漿裝置之上漿液濃度脫離預 定之管理値時，從經紗之濕潤裝置之水分的檢取率之測定 値以靠近其目標之方式控制經紗之濕潤程度，使該上漿液 濃度被控制在預定管理値內。 因此，爲了修正在濕潤後經紗上已被稀釋之上漿裝置之 上漿液濃度，不必使補給上漿液濃度——地被修正，一方面 507039 五、發明說明（3) 使一定濃度之上漿液被進行補給，一方面使上漿裝置之上 漿液濃度可被控制在預定之管理値。 依照本發明之第二方面，在具有濕潤裝置及上漿裝置而 預先使經紗濕潤後進行上漿之上漿機中，上漿裝置的上漿 液濃度之控制方法，其特徵爲：分別測定從該經紗之濕潤裝 置的水分之檢取率，及經濕潤之經紗的上漿裝置的上漿液 之檢取率，至少根據這兩個測定値做推定，根據此推定後的 上漿液濃度爲基礎，使該上漿液濃度控制在預定管理値內 〇 因此，不必常設溫度計之下，可連續自動地測定上漿裝置 之上漿液濃度，使上漿裝置之上漿液濃度自動地控制在預 定管理値內。 依照本發明之第三方面，在具有濕潤裝置及上漿裝置而 預先使經紗濕潤後進行上漿之上漿機中，上漿裝置的上漿 液濃度之控制方法，其特徵爲：分別測定從該經紗之濕潤裝 置的水分之檢取率，及經濕潤之該經紗的上漿裝置的上漿 液之檢取率，至少根據這兩個測定値做推定，被推定後上漿 裝置之上漿液濃度脫離預定之管理値時，以一對絞出輥控 制，使經紗之濕潤裝置之水分的檢取率之測定率，以靠近目 標値之方式而控制經紗之濕潤程度，使該上漿液濃度被控 制在預定管理値內。 因此，僅在一對絞出輥之間進行絞出壓的增減，而使經紗 之水分檢取率產生變化，故可以最簡單的方式，使上漿裝置 507039 五、發明說明（4) 之上漿液濃度自動地被控制在預定之管理値內。 而且，水分之檢取率是由新補充到濕潤裝置之水分量及 各補給間經上漿後之經紗量所導出，上漿液之檢取率是由 新補充到上漿裝置之一定濃度的上漿液量及各補給間被上 漿後之經紗量所導出。 再者，水分之檢取率不僅是由一對絞出輥之間所產生的 絞出壓增減來控制，亦可由經紗於濕潤裝置的浸泡量進行 調整，由上漿前以乾燥裝置調整乾燥溫度而達成控制。 [導出推定上漿裝置之上漿液濃度之計算式] 首先，一開始時濃度計非爲常設，故須導出經紗之該濕潤 裝置的水分檢取率或上漿前經紗之水分率及被濕潤之經紗 的上漿裝置的上漿液之檢取率之測定値等用來推定上漿裝 置之上漿液濃度之計算式。 設經紗之濕潤裝置的水分之檢取率爲PW(%)，其中，經紗 於上漿裝置釋出之水分率爲PWA(%)，經紗未釋出而保持之 水分率爲PWB(%)而成立下式公式（1 )。 PW = PWA + PWB··…（1 ) 此時，由濕潤裝置出來到進入上漿裝置爲止，經紗以乾燥 用之熱圓筒或熱風等乾燥裝置乾燥後，此種乾燥裝置乾燥 後、上漿前之經紗之水分率定爲PW(%)。但是，此水分率中， 須剔除未預先濕潤時即保持之水分率。 其次，上漿裝置內的上漿液量，會隨著運轉中由經紗所檢 取、此部份的補給而變化。 507039 五、發明說明（5) 在此，設使上漿裝置內可塡滿最大上漿液容量爲L(Kg)， 此時之濃度設爲D(%)。而且，由上漿裝置前一次之上漿液 之補給終了開始，到新的上漿液之補給終了爲止，經上漿後 的經紗量以M( Kg)表示。其上漿裝置之上漿液濃度被稀釋， 與其間被經紗所檢取之總量的上漿液濃度相等，此濃度設 爲DD(%)，上漿量除液量，即上漿液容量及經紗釋出之水分 量之和相除，便可求得下式公式（2 )。 DD=100LXD/( 100 L + PWAXM)....(2) 此時，須補給到上漿裝置之上漿液之純糊液成分設爲 SS ( Kg )，由經紗所檢取之上漿液總量（ps X μ )與此濃度DD 相乘後，便可求得下式公式（3 )。在此，PS ( %)是指經紗於上 漿裝置內之上漿液檢取率。 SS = l/100XLXDxPSXM/( 1 0 0L + PWA X Μ)…·（ 3 ) 而且，須補給之上漿液容量設爲LL(Kg)時，經紗於上漿裝 置內所檢取之上漿液總量與經紗在上漿裝置內釋出水分（Μ XPWA)相減便以公式（4)表示。 LL = M/100X (PS-PWA)... . (4) 在此，須補給之上漿液濃度設爲DS(%)時，補給之純上漿 液成分S S與補給之上漿液容量LL相除便以公式（5 )表示 〇 DS = PS XD / { (PS-PWA) X ( 1+PWAXM / 100L) }….（5) 在此，使經紗不預先濕潤而上漿時，設其從上漿裝置之上 漿液之檢取率爲A(%)時，經預先濕潤後之上漿裝置之上漿 507039 五、發明說明（6) 液檢取率PWB，與在上漿裝置中經紗未釋水分而保持之水分 率之和以PS表示，其公式（6 )表示如下。 A = PWB + PS …·（6) 而且，將公式（1)代入公式（6)中，可導出公式（7)如下。 PWA = PW-A + PS·.· · (7) 再者，公式（7 )代入公式（5 )時，須補給之上漿液濃度DS ( % ) 便可由公式（8)導出。 DS = PS X D / { ( A-PW) X { ( 1 - Μ/ 100LX ( A - PW - PS ) ) } ... . ( 8 ) 而且，由公式（8)可導出上漿裝置之上漿液濃度D如下列 公式（9)。 D = DS/PSX (A-PW) X {(1-M/100LX (A-PW-PS))}··· · (9) 公式（9 )中，前述經紗不預先濕潤而上漿時，從上漿裝置 之上漿液之檢取率A，可由在相同條件之經紗在不經濕濶即 上漿等條件下的實際數據求得定數。而且上漿裝置內之最 大上漿液容量L亦爲設備條件之定數。再者，須補給之上 漿液濃度DS，在補給之上漿液相同之限制下，預先開始測定 的話亦爲定數。而且，前一次之上漿液之補給到上漿裝置 終了開始，到新的上漿液補給終了爲止，便可輕易地求出已 經紗量Μ做爲的上漿中之生產量。 因而，運轉中經紗之濕潤裝置的水分之檢取率爲PW、或 上漿前之經紗之水分率PW、經濕潤的經紗於上漿裝置之上 漿液檢取率PS各個被測定的話，便可由公式（9)很輕易地 推算出上漿裝置之上漿液濃度D。 507039 五、發明說明（7) 來自上漿裝置之上漿液檢取率PS，可由前一次上漿液補 給後，新補給上漿液量MS (Kg)除以其間所被上漿之經紗量 Μ推出，可得公式（1 0 )如下。 PS = MS/MX 100·" . ( 10) 而且，來自濕潤裝置的水分之檢取率PW，可由其間補給到 濕潤裝置之水分量MW( Kg )除以同樣之Μ推出，可得公式（1 1 ) 如下。 PW = MW/M X 100... .(11) 在此，經紗從濕潤裝置出來到進入上漿裝置爲止，用熱圓 筒的熱風之乾燥裝置時，以此裝置所乾燥之水分率定爲C( %) 時，此情況下經紗的水分之檢取率PW可由公式（1 2 )表示如 下。 PW=MW/MX 100-C... . ( 12) 另一方面，來自經紗之濕潤裝置的水分之檢取率爲PW，或 上漿前之經紗之水分率PW，可由公式（9 )導出公式（1 3 )如下 〇 PW = A- 1 /2M X [ ( 100L + M X PS) - { ( 100L + M X PS)2-4M X 100L X D/DSXPS}W2]··· · ( 13) 此公式（1 3 )中，代入上漿液濃度之管理値所求得之來自 經紗之濕潤裝置的水分之檢取率PW，做爲目標値PW g標値 〇 因而，當上漿裝置之上漿液濃度偏離管理値時，可將公式 (1 1 )所求得目前經紗於該濕潤裝置的水分之檢取率PW測 507039 五、發明說明（8) 定値，與公式（1 3 )所求得的水分之檢取率目標値PW g標値比 較，若使目前之檢取率pw控制在靠近此目標値PW 0標値時， 所偏離之上漿液濃度會靠近管理値。即，上漿裝置之上漿 液濃度在偏離管理値時，來自經紗之濕潤裝置的水分之檢 取率或上漿前之經紗之水分率pw之測定値，即現狀値控制 在接近該目標値pw @標値時，可使上漿液濃度回復到管理値 〇 [Μ與L相較下小很多的情況] 公式（9 )中，上漿裝置之上漿液補給之故，新補給之前被 上漿之經紗量M( Kg)與最大上漿液容量L(Kg)相較下小很 多的情況下，即上漿液補給之時間間隔近於連續補給的情 況下，公式（9 )近似公式（1 4 )。 D = DS/PS X (A-PW)…·（14) 亦即，上漿裝置之上漿液濃度D幾乎與上漿裝置之容量 或經紗上漿量無關。 而且，從公式（1 4 )導出公式（1 5 )及公式（1 6 )，來自經紗之 濕潤裝置的水分之檢取率PW，與須補給到上漿裝置之上漿 液濃度DS(%)亦近乎相似。 PW = A-D/DS XPS... . ( 15) DS = DXPS/(A-PW)... . ( 16) [由經紗控制之濕潤裝置的水分檢取率之方法] 由經紗控制之濕潤裝置的水分檢取率之方法中，是以裝 設在濕潤裝置上之絞出輥之絞出壓調節而進行的。 -10- 507039 五、發明說明（9) A :上漿裝置之上漿液濃度比管理値低之情況 上漿裝置之上漿液濃度比管理値低之情況下，現狀之經 紗的水分之檢取率PW，比從公式（1 3 )所求出之水分之檢取 率目標値PW g標値爲高。因而，可由絞出輥間的絞出壓的增 加，而使經紗的水分之檢取率PW減少，使其被控制靠近目 標値PW s標値。其結果，可使上漿裝置之上漿液濃度靠近管 理値。 B :上漿裝置之上漿液濃度比管理値高之情況 反之，當上漿裝置之上漿液濃度比管理値高之情況下，現 狀之經紗的水分之檢取率PW，會比從公式（1 3 )所求出之水 分之檢取率目標値PW g標値爲低。因而，可由絞出輥間的絞 出壓的減少，而使經紗的水分之檢取率 PW目標値增加，使其被控制靠近目標値PW g標値。其結果， 可使上漿裝置之上漿液濃度靠近管理値。 C :濕濶裝置與上漿裝置之間奘設有使經紗乾燥用之乾燥裝 置之情形 而且，經紗從濕潤裝置出來而進入上漿裝置爲止之間，設 置有以熱圓筒或熱風乾燥之乾燥裝置的情況時，如上述，不 僅由絞出輥之間的絞出壓控制，並且由此乾燥裝置或乾燥 時間控制，而使上漿前經紗的水分率PW g胃μ，控制到靠近 目標値PW g標値。其結果，可使上漿裝置之上漿液濃度靠近 管理値。 附圖之簡單說明 -1 1 - 507039 五、發明說明（1〇) 第1圖是預先使經紗被濕潤後進行上漿之上漿機中具有 之濕潤裝置及上漿裝置及紗條捲取裝置的示意圖。 第2圖是顯示各機器之連接關係的方塊圖。 第3圖是顯示控制上漿裝置之上漿液濃度在管理値的控 制方法之流程圖。 本發明較佳奮施例之詳細說明 將根據本發明之實施例，參照圖面而說明。 第1圖爲，上漿裝置1 0之前方裝有濕潤裝置2，預先使經 紗被濕潤後進行上漿之上漿機之示意圖。經紗1經由導輥 22而被導入濕潤裝置2中，經由浸泡輥4而被浸入水3之 後，經由絞出輥5使濕潤水分之局部被絞出。其後濕潤後 之經紗8再經由熱圓筒9而使水分之局部被乾燥之後，導 入上漿裝置1 0中。濕潤後之經紗8經由浸泡輥20而浸入 上漿液1 1之後，以絞出輥21而使部分上漿液被絞出。其 後，經紗8經由熱圓筒1 9而使水分乾燥之後，被捲取在紗 桿1 5上。 上漿機中具有程序裝置16,用以輸入求出自上述上漿裝 置1 0之上漿液之檢取率PS用之公式（1 0 )、濕潤裝置2及 上漿裝置1 0之間設置有乾燥經紗8用熱圓筒9時，求出上 漿前經紗的水分率PW用之公式（1 2 )、求出上漿裝置1 〇之 上漿液濃度D用之公式（9 )及求出經紗8之濕潤裝置2的 水分檢取率目標値PW g標値用之公式（1 3 )。 參照第2圖，程序裝置1 6中，上漿機中必要之部份之資 -12- 507039 五、發明說明（11) 訊以電氣訊號輸入，同時以人工輸入的方式將必要之資訊 輸入輸出入裝置17反之，程序裝置16所計算之資訊亦可 由輸出入裝置17處顯示。再者，根據程序裝置16所計算 之結果，而可達成使濕潤裝置2之絞出輥5的絞出壓有所 增減、亦可調整由浸泡輥4使經紗1在濕潤裝置2中之浸 泡量、調整做爲上漿前之乾燥手段用之熱圓筒9之乾燥溫 度達成控制。 上漿裝置1 0之上漿液1 1的量，被濕潤之經紗8所檢取 之故而在運轉中減少。因而，爲了管理上漿裝置1 〇中上漿 液1 1的量，上漿裝置內之上漿液量被減少一定量之情況時， 上漿液補給裝置30會自動地補給上漿液1 2到回到原來之 管理容量L爲止。而且，因濕潤裝置2之水3的容量亦被 經紗1所檢取而減少，故由水補給裝置40補給補給水6。 由水補給裝置40所補給之補給水6，與上漿液補給裝置30 所補給上黎液12之開始補給爲同步進行，當回復當初之管 理容量時，補給即告終了。此時，流量計2 3及7分別測定 補給上漿液1 2及補給水6之補給量，使各個値分別做爲公 式（10)之被補給上漿液MS、及公式（12)之補給水分量MW 之値，而自動地輸入程序裝置16。 同時，由上漿液補給裝置30所補給之上漿液12之補給 終了時之時點亦被輸入程序裝置1 6中。然後，根據安裝在 拉緊_ 13上之轉數積算計18的資訊，或輸出入裝置17所 輸入之經紗種類等各條件，程序裝置1 6會計算從上次補給 -13- 507039 五、發明說明（彳2) 上漿液1 2之補給終了之後，到新上漿液被補給終了爲止之 間被上漿之經紗量Μ。其計算結果會代入公式（1 0 )、公式 (12)、公式（9)、及公式（13)中。 在此，公式（1 2 )之C，爲被濕潤後之經紗8經由熱圓筒9 所乾燥之水分率（％)。在此，假定運轉中之乾燥條件爲一定， 水分率C之値會以實際進行驗證後之計算値以定數輸入輸 出入裝置17中。 上漿液11之濃度被濕潤後之經紗8所釋出之水分所稀 釋。因而，補給上漿液1 2之濃度預先以此預測而設定成較 高之値。在此實施例中，使用近似式（16’），求出須補給之 上漿液濃度DS，進行此濃度之槪算。此式（1 6 )中，將分別代 入上漿裝置1 0之上漿液濃度D中，運轉前所實例之上漿液 1 1的濃度値，與經紗不預先濕潤而上漿時，從上漿裝置所得 之上漿液檢取率Α中，根據到目前爲止之實際資料所求得 之定數，上漿裝置之上漿液的檢取率PS及上漿前經紗之水 分率PW中假設其運轉中之値。 因此，預先設定成較高之補給上漿液12的濃度DS，會由 槪算値所求出。而且，加上運轉中之其他條件變化等，該預 先被設定成較高補給之上漿液1 2持續進行補給，造成運轉 中之上漿液1 1的濃度，漸漸偏離運囀前上漿液1 1的濃度， 亦即管理値。如此保持下去時，定會損及適當之上漿。 因而，本發明中，爲了知道運轉中上漿裝置10內之上漿 液11的濃度變化，而使用公式（9 )算出此上漿液11的濃度 -14- 507039 五、發明說明（13) 。此數式會輸入到程序裝置1 6中。在公式（9 )中，上漿液 檢取率A、須補給之上漿液濃度DS及最大上漿液容量L被 做爲定數，預先在運轉前輸入輸出入裝置17。在此，上漿液 檢取率A中，分別代入根據到目前爲止之實際資料所求得 之定數、須補給之上漿液濃度DS中，運轉前實際測得之上 漿液12濃度及最大上漿液容量L中，上漿裝置10之上漿 液量的管理容量。 而且，依照所顯示之方法，程序裝置16之公式（10)及公 式（1 2 )中，將代入由流量計23所測定之已補給上漿液量MS 、由流量計7所測定之已補給水分量MW及由轉數積算計 1 8取得之資訊或從經紗之各條件所算出預定間隔上漿之經 紗量Μ之各項之値，此計算値會被代入公式（9 )中。如此， 由上漿液補給裝置3 0進行補給上漿液1 2之補給之時，公 式（9 )之上漿裝置的之上漿液的檢取率PS、濕潤裝置的水 分之檢取率PW及預定間隔上漿之經紗量Μ之値被更新，此 時所計算之上漿裝置10之上漿液濃度D會輸出輸出入裝 置1 7，顯示該値。而且，公式（9 )之輸出値的上漿液濃度D， 在程序裝置1 6中會與上漿裝置1 0之上漿液濃度的管理値 進行比較。 在輸入程序裝置1 6中，由經紗8之濕潤裝置2的水分檢 取率目標値PW g標{直求得公式（1 3 )的上漿液濃度D中，上漿 裝置10之上漿液濃度的管理値會以定數輸入輸出入裝置 17 ° -15- 507039 五、發明說明（彳4) 而且，此公式（1 3 )除了 PW以外之其他各項，與公式（9 )同 樣地由輸出入裝置17進行輸入。因而，公式（13)之計算結 果中以PW所表示之水分率，爲上漿裝置1 〇之上漿液11濃 度的管理値之故，被濕潤後之經紗8在上漿前所必須保有 之水分率。在程序裝置1 6中，會以此公式（1 3 )所得之 PW目標値與此公式（12)所得之PW測定値做爲現狀値進行比 較。而，PW g標値中，若維持在容計範圍內，且現狀値在其範 圍內的話，兩者間使不會產生偏離。 [上漿裝置之上漿液濃度的控制順序] 以下，一面參照流程圖，一面說明上漿裝置1 0之上漿液 濃度的控制順序。 如上所述，程序裝置1 6在上漿裝置1 0進行補給上漿液 1 2之補給時，上漿裝置1 〇之上漿液濃度D(公式（9 )之計算 値）與管理値進行比較（方塊1 )。然後，在上漿液濃度D偏 離管理値時（方塊1中YES之情況），程序裝置1 6將使上漿 裝置1 0之上漿液濃度控制如下。 當上漿裝置1 0之上漿液濃度D低於管理値時（方塊1中 YES之情況），經紗的水分檢取率PW之現狀値，將會顯示其 目標値PW g標値高於容許範圍。但是，水分檢取率PW之現 狀若在該目標値PW目標値之容許範圍內的話（方塊3中NO 之情況），可視爲兩者之間沒有偏離，絞出輥5之絞出壓則 維持現狀。另一方面，若水分檢取率PW之現狀値高於其目 標値PW目標値之容許範圍的話（方塊3中YES之情況），程序 -16- 507039 五、發明說明（15) 裝置16輸出一個信號使濕潤裝置2的絞出輥5之絞出壓 增加，收到該信號後，絞出輥5之絞出壓開始增加（方塊4 ) 。其結果爲，被濕潤後的經紗8的水分檢取率PW被減少。 然後，當水分 檢取率PW之現狀値減少到目標値PW g標値之容許範圍內 的話（方塊3中N0之情況），絞出輥5之絞出壓則維持現狀 。因此，上漿裝置1 0之上漿液濃度D可調整近管理値，或 回復到管理値。 反之，當上漿液1 1的濃度D高於管理値時（方塊2中N0 之情況），經紗的水分檢取率PW之現狀値，將會顯示其目標 値PW g標値低於容許範圍。但是，水分檢取率PW之現狀値 落入其目標値g標値之容許範圍內的話（方塊5中NO之情況 )，可視爲兩者之間沒有偏離，絞出輥5之絞出壓則維持現 狀。另一方面，若水分檢取率PW之現狀値低於其目標値PW 目標値之容許範圍的話（方塊5中YES之情況），程序裝置1 6 會輸出一個信號使濕潤裝置2的絞出輥5之絞出壓減少。 收到該信號後，絞出輥5之絞出壓開始減少（方塊6 )。其結 果爲，被濕潤後的經紗8的水分檢取率PW增加。當水分檢 取率PW之現狀値增加到目標値PW g標値之容許範圍內的話 (方塊5中N0之情況），絞出輥5之絞出壓則維持現狀。因 此，上漿裝置1 0之上漿液濃度D可調整管理値，或回復到 管理値。 在此，絞出輥5之絞出壓之增減程度，可會因經紗之水分 -17- 507039 五、發明說明（16) 檢取率pw之現狀値與目標値之差異程度而改變。而且，本 實施例中，絞出輥5之絞出壓之增減，雖然是以經紗之水分 檢取率PW之現狀値慢慢地靠近目標値而變化，但是亦可以 一次變化所需的量。此外，程序裝置1 6可計算比較補給上 漿液1 2補給到上漿裝置1 0時，經紗之水分檢取率PW之現 狀値與目標値，並視其情形使絞出輥5之絞出壓有所增減 〇 而且，經紗之水分檢取率PW會由於浸泡輥4之位置調整， 而使經紗1可經由在濕潤裝置2浸泡量的調整而有所增減 〇 再者，在上漿裝置10進行上漿之前，可經由熱圓筒9調 整乾燥溫度而調整被濕潤後之經紗8的乾燥程度，使經紗 之水分檢取率PW能有所增減。 此外，在增減經紗之水分檢取率之情況下，可全部的調整 絞出輥5之絞出壓、浸泡輥4之浸泡量及熱圓筒9之乾燥 溫度的數値，亦可在其中任選多個數値，或單獨調整任一個 數値。 本實施例中，PW之目標値爲保持在容許範圍內，若pw之 現狀値在此範圍內的話，絞出輥5之絞出壓則毋須變更。 在此所稱之「容許範圍」，一般係指誤差之範圍，假如全部 沒有誤差的話，PW之目標値設定爲特定値，容許範圍不被設 定。同理，在全部沒有誤差的情況下，方塊3及方塊5之作 業亦可省略。但是，考量到上漿機台的種種條件或狀態時， -18- 507039 五、發明說明（17) 此「容量範圍」亦可包含誤差以外之許多實質數値範圍° 另，本實施例中，因濕潤裝置2與上漿裝置1 0之間，設有 乾燥經紗8用的熱圓筒9，故使用公式（1 2 )求出上漿前經紗 之水分檢取率PW，若是在不設置此乾燥裝置之情況下，則以 用公式（1 1 )求出濕潤裝置之經紗之水分檢取率PW較佳。 再者，輸出入裝置17上，一般雖是顯示由程序裝置16所 計算之上漿液1 1濃度，但是其他輸入到程序裝置1 6之全 部値，及在此所計算之全部値亦同時可被顯示出來。 符號說明 D...上漿液濃度 PW...水分檢取率 M...經紗量 PS·..上漿液的檢取率 MS...被補給上漿液 DS·.·補給之上漿液濃度 MW…補給水分量 1.. .經紗 2.. .濕潤裝置 3···水 4.. .浸泡輥 5.. .絞出輥 6.. .補給水 7,23···流量計 -19- 507039 五、發明說明（18) 8.. .經濕潤後之經紗 9.. .熱圓同 10.. .上漿裝置 1 1 ...上漿液 1 2 .補給上漿液 13.. .拉緊輥 15…紗桿 16.. .程序裝置 1 7 ...輸出入裝置 18.. .轉數積算計 1 9...熱圓筒 20.. .浸泡輥 21.. .絞出輥 22.. .導輥 30.. .上漿液補給裝置 40.. .水補給裝置 -20-507039 V.

In general, warp yarns are more effective when they pass through hot water at 80 ° C to 90 ° C and then sizing after drying to a certain moisture. On the other hand, when the previously wetted warp yarn passes through the sizing device, the slurry on the sizing device is diluted with the water released from the wetted warp yarn. Therefore, in order to maintain proper sizing on the warp yarns, it is necessary to control the concentration of the slurry on the sizing device to the target grate. Therefore, it is planned to prepare a high-concentration sizing solution having a higher concentration than the sizing device on the sizing device. When the sizing device is to be replenished due to the sizing solution detected by the wet warp yarn, this high-concentration upper sizing solution can be used. Achieve slurry concentration management above the sizing device. However, if the concentration of the sizing agent for replenishment does not correspond correctly to the moisture detection rate of the warp yarn, or the moisture content of the warp yarn before sizing, or the detection rate of the sizing agent on the warped yarn after wetting, continue to replenish the sizing solution at a certain concentration. At this time, the slurry concentration on the sizing device will gradually deviate from the management 値, so that the situation in which the warp yarns cannot be sizing properly may occur. Therefore, in the conventional sizing machine, because the concentration of the slurry on the sizing device must be 507039. 5. Description of the invention (2) It is often adjusted in the management unit, so a concentration meter is installed. When sizing liquid is to be replenished, it can be used to To calculate and measure the sizing solution concentration of the sizing device, the sizing solution concentration to be replenished must be adjusted corresponding to the obtained amount. Actually, two kinds of sizing liquid and water with high concentration and low concentration are prepared, and these sizing liquid and water are mixed according to the above-mentioned measurement according to the aforementioned ratio at the time of replenishment to adjust the sizing liquid concentration. However, in order to correct the slurry concentration on the sizing device that has been diluted on the warp after wetting, the mixing of the sizing solution and water and the supply of the sizing solution on the sizing solution must be adjusted one by one, and the handling and procedures are more complicated, so There is no automatic control over management. Therefore, it is desired to develop a method of maintaining the supply of the sizing liquid with a certain concentration so that the concentration of the slurry on the sizing device can be controlled to a predetermined target value. Brief description of the invention According to the main aspect of the present invention, in a sizing machine having a wetting device and a sizing device and sizing the warp yarn in advance, the method for controlling the slurry concentration on the sizing device of the present invention has the characteristics For: the concentration of the slurry on the sizing device can be detected or estimated. When the concentration of the slurry on the sizing device deviates from the predetermined management, the measurement of the moisture detection rate from the wetting device of the warp yarn will be closer to its target. In this way, the degree of wetting of the warp yarn is controlled so that the sizing concentration is controlled within a predetermined management range. Therefore, in order to correct the concentration of the slurry on the warp yarns that have been diluted on the sizing device after wetting, it is not necessary to make the supply sizing concentration-the ground is corrected. On the one hand, 507039 V. Description of the invention Replenishment, on the one hand, allows the slurry concentration on the sizing device to be controlled to a predetermined management level. According to a second aspect of the present invention, in a sizing and sizing machine having a wetting device and a sizing device and wetting the warp yarn in advance, the method for controlling the sizing concentration of the sizing device is characterized in that: The moisture detection rate of the warp wetting device and the sizing solution of the sizing device of the wet warp are estimated based on at least these two measurements. Based on the estimated sizing concentration, The sizing concentration is controlled within the predetermined management range. Therefore, a standing thermometer is not necessary, and the slurry concentration on the sizing device can be continuously and automatically measured, so that the slurry concentration above the sizing device is automatically controlled within the predetermined management range. According to the third aspect of the present invention, in a sizing and sizing machine having a wetting device and a sizing device and wetting the warp yarn in advance, the method for controlling the sizing concentration of the sizing device is characterized in that: The moisture detection rate of the wetting device of the warp yarn and the sizing solution of the sizing device of the warp yarn that has been wetted are estimated based on at least these two measurements. After the estimation, the concentration of the slurry on the sizing device is separated. During the predetermined management cycle, a pair of take-out rollers are used to control the measurement rate of the moisture detection rate of the warp wetting device, and the wetness of the warp yarn is controlled in a manner close to the target yarn so that the sizing concentration is controlled at Schedule management. Therefore, only the twisting pressure is increased or decreased between a pair of twisting rollers, and the moisture detection rate of the warp yarn is changed. Therefore, the sizing device 507039 can be the simplest way. 5. Description of the invention (4) Sizing concentration is automatically controlled within a predetermined management volume. In addition, the moisture detection rate is derived from the amount of water newly replenished to the wetting device and the amount of warp yarn after sizing in each supply. The sizing fluid detection rate is newly added to a certain concentration of the sizing device. The amount of slurry and the amount of warp yarn after sizing between each supply are derived. In addition, the moisture detection rate is not only controlled by the increase or decrease of the draw pressure generated between a pair of draw rolls, but also can be adjusted by the soaking amount of the warp yarn in the wetting device, and the drying is adjusted by the drying device before sizing. Temperature reached control. [Derive the calculation formula of the estimated slurry concentration on the sizing device] First, at the beginning, the densitometer is not permanent, so the moisture detection rate of the wetting device of the warp yarn or the moisture content of the warp yarn before sizing and the moisture The measurement of the sizing rate of the sizing device of the warp yarn sizing device is used to estimate the calculation formula of the sizing concentration on the sizing device. The moisture detection rate of the wetting device equipped with warp yarns is PW (%). Among them, the moisture content released by warp yarns in the sizing device is PWA (%), and the moisture content that is not released by warp yarns is PWB (%). The following formula (1) is established. PW = PWA + PWB ... (1) At this time, from the wetting device to the sizing device, the warp yarn is dried by a drying device such as a hot cylinder or hot air for drying. After the drying device is dried, the sizing is performed. The moisture content of the previous warp yarn is determined as PW (%). However, in this moisture content, it is necessary to exclude the moisture content which is maintained without being wetted in advance. Secondly, the amount of sizing liquid in the sizing device will change with the recharge detected by the warp yarn during operation. 507039 5. Description of the invention (5) Here, the maximum sizing liquid capacity that can be filled in the sizing device is L (Kg), and the concentration at this time is D (%). In addition, from the end of the previous resupply of the sizing device to the end of the new sizing replenishment, the amount of warp after sizing is expressed in M (Kg). The sizing concentration on the sizing device is diluted to be equal to the total sizing concentration detected by the warp yarn during this time. This concentration is set to DD (%). The sizing amount is divided by the liquid amount, that is, the sizing capacity and warp yarn release. Dividing the sum of the water content, the following formula (2) can be obtained. DD = 100LXD / (100 L + PWAXM) .... (2) At this time, the pure paste composition of the slurry to be supplied to the sizing device is set to SS (Kg), and the total size of the upper slurry detected by the warp yarn. After multiplying the amount (ps X μ) by this concentration DD, the following formula (3) can be obtained. Here, PS (%) refers to the detection rate of the size of the warp yarn in the sizing device. SS = l / 100XLXDxPSXM / (1 0 0L + PWA X Μ) ... (3) In addition, when the size of the slurry to be replenished is set to LL (Kg), the total amount of slurry detected by the warp in the sizing device Subtracting from the moisture released by the warp yarn in the sizing device (M XPWA) is expressed by formula (4). LL = M / 100X (PS-PWA) ... It is expressed by the formula (5). DS = PS XD / {(PS-PWA) X (1 + PWAXM / 100L)} ... (5) Here, when the warp yarn is sizing without being wetted in advance, it is set from above. When the detection rate of the slurry on the sizing device is A (%), the sizing device is sized on the sizing device after being wetted in advance 507039. V. Description of the invention (6) The liquid detection rate PWB is similar to the warp in the sizing device. The sum of the moisture content retained by the water is expressed by PS, and the formula (6) is expressed as follows. A = PWB + PS… · (6) Furthermore, when formula (1) is substituted into formula (6), formula (7) can be derived as follows. PWA = PW-A + PS ·. ·· (7) Furthermore, when formula (7) is substituted into formula (5), the slurry concentration DS (%) on top of the recharge can be derived from formula (8). DS = PS XD / {(A-PW) X {(1-Μ / 100LX (A-PW-PS))) .... (8) Moreover, the slurry on the sizing device can be derived from formula (8) The concentration D is as shown in the following formula (9). D = DS / PSX (A-PW) X {(1-M / 100LX (A-PW-PS))} ... (9) In formula (9), when the aforementioned warp yarn is sizing without pre-wetting, From the detection rate A of the sizing liquid on the sizing device, a certain number can be obtained from the actual data of warp yarns under the same conditions without sizing under wet conditions. In addition, the maximum sizing capacity L in the sizing device is also a fixed number of equipment conditions. In addition, the concentration DS of the slurry above the replenishment is required to be determined in advance if the measurement is started in advance under the same restrictions as the slurry on the replenishment. In addition, from the previous sizing replenishment to the end of the sizing device, and until the new sizing replenishment is completed, the production amount in the sizing can be easily determined. Therefore, if the moisture detection rate of the warp wetting device during operation is PW, or the moisture content of the warp yarn before sizing PW, and the wet warp yarn on the sizing device, the PS detection rate PS can be measured. Equation (9) can easily calculate the slurry concentration D above the sizing device. 507039 V. Description of the invention (7) The detection rate PS from the sizing device can be derived from the newly replenished sizing amount MS (Kg) after the previous sizing replenishment divided by the sizing warp amount M in the meantime. The formula (1 0) can be obtained as follows. PS = MS / MX 100 · ". (10) Moreover, the detection rate PW of the moisture from the humidifying device can be derived by dividing the amount of water MW (Kg) supplied to the humidifying device by the same M, and the formula ( 1 1) is as follows. PW = MW / MX 100 .... (11) Here, when the warp yarn exits the wetting device and enters the sizing device, when using a hot-cylinder hot air drying device, the moisture content dried by this device is set to C (%), The detection rate PW of the moisture in the warp yarn in this case can be expressed by the following formula (1 2). PW = MW / MX 100-C .... (12) On the other hand, the detection rate of the moisture from the wetting device of the warp yarn is PW, or the moisture content of the warp yarn before sizing PW can be derived from formula (9) The formula (1 3) is as follows: PW = A- 1 / 2M X [(100L + MX PS)-{(100L + MX PS) 2-4M X 100L XD / DSXPS} W2] ··· (13) This formula In (1 3), the management of the sizing solution concentration is substituted for the moisture detection rate PW obtained from the wetting device of the warp yarn as the target (PW g standard). Therefore, when the slurry concentration on the sizing device deviates In the management of maggots, the moisture detection rate PW of the current warp yarn in the wetting device obtained by formula (1 1) can be measured by PW 507039. 5. Description of the invention (8) Determination of hydration and the moisture content obtained by formula (1 3) Comparison of the detection rate target (PW g standard), if the current detection rate pw is controlled to be close to this target (PW 0 standard), the slurry concentration above the deviation will be close to the management level. That is, when the concentration of the slurry on the sizing device deviates from the management threshold, the detection rate of the moisture from the wetting device of the warp yarn or the moisture ratio pw of the warp yarn before sizing is measured. @ 标 値 When the sizing solution concentration can be restored to the management 値 [M and L is much smaller than the case] [Formula (9), the sizing device is resupplied by the sizing device in the formula (9). In the case where the warp amount M (Kg) and the maximum sizing capacity L (Kg) are much smaller, that is, when the sizing replenishment time interval is close to continuous replenishment, formula (9) approximates formula (1 4). D = DS / PS X (A-PW) ... (14) That is, the slurry concentration D on the sizing device is almost independent of the capacity of the sizing device or the sizing amount of the warp yarns. Furthermore, formula (1 5) and formula (16) are derived from formula (1 4). The moisture detection rate PW from the warp wetting device and the slurry concentration DS (%) which must be replenished to the sizing device are also obtained. Almost similar. PW = AD / DS XPS .... (15) DS = DXPS / (A-PW) .... (16) [Method of moisture detection rate of the wetting device controlled by warp yarns] Wet device controlled by warp yarns In the method of moisture detection rate, the twisting pressure of the twisting roller installed on the humidifying device is adjusted. -10- 507039 V. Description of the invention (9) A: When the slurry concentration on the sizing device is lower than the management 値 When the slurry concentration on the sizing device is lower than the management 値, the current moisture detection rate of the warp yarn PW is higher than the target (PW g) of the moisture detection rate obtained from the formula (1 3). Therefore, by increasing the skein pressure between the skein rolls, the moisture detection rate PW of the warp yarn can be reduced, and it can be controlled to be close to the target 値 PW s mark 値. As a result, the slurry concentration on the sizing device can be brought closer to the management tank. B: Conversely, when the slurry concentration on the sizing device is higher than the management ratio, when the slurry concentration on the sizing device is higher than the management ratio, the current moisture detection rate PW of the warp yarn will be higher than the formula (1 3) The target (PW g) of the obtained moisture detection rate is low. Therefore, the reduction in the draw pressure between the draw rolls can increase the detection rate PW target 检 of the moisture content of the warp yarns, so that it can be controlled to approach the target 値 PW g mark 値. As a result, the concentration of the slurry on the sizing device can be brought closer to the management mash. C: A drying device for drying the warp yarn is installed between the wet beading device and the sizing device, and the warp yarn is dried by a hot cylinder or hot air until it exits the wetting device and enters the sizing device. In the case of the device, as described above, not only the draw pressure between the draw rolls but also the drying device or the drying time is controlled so that the moisture content PW g of the warp yarn before sizing is controlled close to the target 値PW g is marked. As a result, the concentration of the slurry on the sizing device can be brought closer to the control tank. Brief description of the drawings-1 1-507039 5. Description of the invention (10) The first figure is a wetting device, a sizing device and a sliver winding device provided in the sizing machine after the warp yarns are wetted beforehand. Schematic. Fig. 2 is a block diagram showing the connection relationship of each machine. Fig. 3 is a flow chart showing a control method for controlling the slurry concentration on the sizing device in the management tank. Detailed Description of the Preferred Embodiments of the Invention The embodiments of the present invention will be described with reference to the drawings. Fig. 1 is a schematic view of a sizing and sizing machine in which a wetting device 2 is installed before the sizing device 10 and the warp yarn is wetted in advance. The warp yarn 1 is introduced into the wetting device 2 through the guide roller 22, and is immersed in the water 3 through the soaking roller 4, and then the moistened water is partially tangled out through the take-out roller 5. After that, the moist warp yarn 8 is partially dried by passing through the hot cylinder 9 and then introduced into the sizing device 10. After the wet warp yarn 8 is immersed in the sizing liquid 11 through the immersion roller 20, a part of the sizing liquid is skeined out by the squeegeeing roller 21. After that, the warp yarn 8 is dried by passing through the thermal cylinder 19, and is then wound around the yarn rod 15. The sizing machine has a program device 16 for inputting the formula (1 0) for obtaining the detection rate PS of the slurry from the above sizing device 10, and between the wetting device 2 and the sizing device 10, When the hot cylinder 9 is used for drying the warp yarn 8, the formula (12) for determining the moisture content PW of the warp yarn before sizing, the formula (9) for determining the slurry concentration D on the sizing device 10, and the warp yarn are obtained The formula (1 3) used for the moisture detection rate target (PW g standard) of the wet device 2 of 8. Referring to Figure 2, the necessary parts of the sizing machine in the program device 16-12-507039 V. Description of the invention (11) The signal is input by electrical signals, and the necessary information is input and output manually. Conversely, the input device 17 can also display the information calculated by the program device 16 from the input / output device 17. Furthermore, according to the calculation result of the program device 16, the twisting pressure of the weaving roller 5 of the wetting device 2 can be increased or decreased, and the soaking roller 4 can be adjusted to soak the warp yarn 1 in the wetting device 2. The amount and adjustment of the drying temperature of the hot cylinder 9 used as the drying means before sizing are controlled. The amount of the slurry 11 on the sizing device 10 is detected by the moist warp yarn 8 and is reduced during operation. Therefore, in order to manage the amount of the sizing liquid 11 in the sizing device 10, when the amount of the sizing liquid in the sizing device is reduced by a certain amount, the sizing liquid supply device 30 will automatically replenish the sizing liquid 12 to the original Up to the management capacity L. In addition, since the capacity of the water 3 of the wetting device 2 is also detected by the warp yarn 1 and reduced, the replenishing water 6 is replenished by the water replenishing device 40. The replenishment water 6 replenished by the water replenishing device 40 is synchronized with the initial replenishment of the upper liquid 12 replenished by the sizing liquid replenishing device 30. When the original management capacity is restored, the replenishment ends. At this time, the flowmeters 2 3 and 7 measure the replenishment amounts of the replenishing sizing liquid 12 and the replenishing water 6, respectively, so that each puppet is used as the replenishing sizing liquid MS of formula (10) and the replenishing water amount of formula (12). MW is automatically entered into the programming device 16 automatically. At the same time, the point at which the replenishment of the slurry 12 supplied by the slurry supply device 30 ends is also input to the program device 16. Then, according to the information of the revolution totalizer 18 installed on the tensioner_13, or the warp yarn type input to the input / output device 17, the program device 16 will calculate the last supply -13-507039. V. Invention Explanation (彳 2) After the replenishment of the sizing liquid 12 is completed, the amount of warp yarn M that is sizing until the new sizing liquid is replenished. The calculation result will be substituted into formula (1 0), formula (12), formula (9), and formula (13). Here, C of the formula (1 2) is the moisture content (%) of the wetted warp yarn 8 dried by the hot cylinder 9. Here, it is assumed that the drying conditions during the operation are constant, and the moisture content C will be calculated and then input to the output device 17 by a fixed number. The concentration of the sizing solution 11 is diluted by the moisture released from the wetted warp yarn 8. Therefore, the concentration of the replenishing sizing liquid 12 is set to a relatively high level based on this prediction. In this embodiment, the approximate formula (16 ') is used to find the sizing solution concentration DS to be replenished, and the concentration is calculated. In this formula (16), the sizing concentration D on the sizing device 10 is substituted into the sizing concentration D on the sizing device 10 before operation, and when the warp yarns are sizing without being wetted in advance, from the sizing device Among the obtained upper slurry detection rate A, based on the actual data obtained so far, the detection ratio PS of the slurry on the sizing device and the moisture content PW of the warp yarn before sizing are assumed to be in operation. value. Therefore, the concentration DS of the feed sizing liquid 12 which is set to be high in advance is obtained by the calculation. In addition, along with other changes in conditions during operation, the pre-set is set to a higher supply on top of the slurry 1 2 to continue the replenishment, causing the concentration of the top slurry 1 1 during operation to gradually deviate from the level of the slurry 1 1 before operation. Concentration, which means management radon. When this is maintained, proper sizing will be compromised. Therefore, in the present invention, in order to know the concentration change of the slurry 11 in the sizing device 10 during operation, the concentration of the slurry 11 is calculated using formula (9) -14-507039 5. Explanation of the invention (13). This number is entered in the programming device 16. In the formula (9), the sizing liquid detection rate A, the concentration of the sizing liquid DS, and the maximum sizing capacity L are set as fixed numbers, and the input / output device 17 is inputted before operation. Here, the sizing liquid detection rate A is respectively substituted into the fixed value DS which must be replenished based on the actual data obtained so far. The concentration of the upper slurry 12 and the maximum sizing liquid are actually measured before the operation. The capacity L is a management capacity for the amount of slurry on the sizing device 10. Furthermore, according to the displayed method, the formula (10) and formula (12) of the program device 16 are substituted into the replenished sizing amount MS measured by the flow meter 23 and the replenished moisture measured by the flow meter 7. The amount of MW and the information obtained from the revolution totalizer 18 or each of the warp yarns sizing at a predetermined interval calculated from the conditions of the warp yarns will be substituted into formula (9). In this way, when the sizing liquid replenishment is performed by the sizing liquid replenishing device 30, the detection ratio PS of the upper slurry of the sizing device PS, the detection ratio PW of the moisture of the wetting device, and the predetermined interval are given by formula (9). The size of the sizing warp yarn M is updated. At this time, the calculated slurry concentration D on the size sizing device 10 is output and input to the device 17 to display the size. Moreover, the sizing concentration D of the output 値 of the formula (9) is compared with the management 値 of the sizing concentration on the sizing device 10 in the program device 16. In the input program device 16, the moisture detection rate target 値 PW g of the wetting device 2 of the warp yarn 8 is used to calculate the sizing concentration D of the formula (1 3). Management 値 will use constant input and output devices 17 ° -15- 507039 5. Explanation of the invention (彳 4) In addition, other items of this formula (1 3) except PW are input and output in the same way as formula (9) The device 17 performs input. Therefore, the moisture content represented by PW in the calculation result of formula (13) is the management of the concentration of the slurry 11 above the sizing device 10, and the moisture content of the wetted warp yarn 8 must be maintained before sizing. rate. In the program device 16, the PW target obtained by the formula (1 3) is compared with the PW measurement obtained by the formula (12) as the status quo. However, if the PW g standard is maintained within the capacity range and the current status is within its range, there will be no deviation between the two. [Control procedure of slurry concentration on sizing device] Hereinafter, a control procedure of slurry concentration on the sizing device 10 will be described with reference to a flowchart. As described above, when the program device 16 replenishes the sizing liquid 12 with the sizing device 10, the slurry concentration D on the sizing device 10 (the calculation of formula (9) 値) is compared with the management 値 (block 1 ). Then, when the sizing concentration D deviates from the management time (in the case of YES in block 1), the program device 16 will control the slurry concentration on the sizing device 10 as follows. When the slurry concentration D on the sizing device 10 is lower than the management threshold (in the case of YES in block 1), the current status of the moisture detection rate PW of the warp yarn will display its target (PW g standard) above the allowable range. . However, if the current state of the moisture detection rate PW is within the allowable range of the target (PW target) (in the case of NO in block 3), it can be considered that there is no deviation between the two, and the twisting pressure of the twisting roller 5 is maintained. status quo. On the other hand, if the current status of the moisture detection rate PW is higher than the allowable range of its target (PW target) (in the case of YES in block 3), the program-16-507039 V. Description of the invention (15) The device 16 outputs a The signal increases the unwinding pressure of the unwinding roller 5 of the wetting device 2. After receiving this signal, the unwinding pressure of the unwinding roller 5 starts to increase (block 4). As a result, the moisture detection rate PW of the wetted warp yarn 8 is reduced. Then, when the current state of the moisture detection rate PW is reduced to an allowable range of the target (PW g standard) (the case of No in block 3), the twisting pressure of the unwinding roller 5 is maintained as it is. Therefore, the slurry concentration D on the sizing device 10 can be adjusted to the management volume or returned to the management volume. Conversely, when the concentration D of the sizing liquid 11 is higher than the management value (in the case of NO in box 2), the current state of the moisture detection rate PW of the warp yarns will show that its target 値 PW g standard 値 is lower than the allowable range. However, if the current status of moisture detection rate PW falls within the allowable range of its target (g) (case of NO in block 5), it can be considered that there is no deviation between the two, and the twisting pressure of the twisting roller 5 is Maintain the status. On the other hand, if the current status of the moisture detection rate PW is lower than the allowable range of its target (PW target) (in the case of YES in block 5), the program device 16 will output a signal to cause the winch roll of the wetting device 2 The twisting pressure of 5 is reduced. After receiving this signal, the unwinding pressure of the unwinding roller 5 starts to decrease (block 6). As a result, the moisture detection rate PW of the wetted warp yarn 8 increases. When the current state of the moisture detection rate PW increases to an allowable range of the target (PW g standard) (the case of NO in block 5), the twisting pressure of the twisting roll 5 maintains the current state. Therefore, the slurry concentration D on the sizing device 10 can be adjusted to the management volume, or returned to the management volume. Here, the degree of increase or decrease of the skein pressure of the skein roll 5 may be changed due to the difference between the current state 値 and the target 检 of the pick-up rate pw. Moreover, in the present embodiment, the increase or decrease of the drawout pressure of the drawout roll 5 is changed according to the current state of the moisture detection rate PW of the warp yarns (close to the target), but it can be changed at a time. . In addition, the program device 16 can calculate and compare the current status 値 and target 水分 of the moisture detection rate PW of the warp yarn when the sizing liquid 12 is replenished to the sizing device 10, and the squeegee pressure of the squeegee roller 5 is determined according to the situation Increased or decreased. Moreover, the moisture detection rate PW of the warp yarn will be increased or decreased by adjusting the soaking amount in the wetting device 2 due to the adjustment of the position of the soaking roller 4. Furthermore, in the sizing device, 10 Before sizing, the drying temperature of the wetted warp yarn 8 can be adjusted by adjusting the drying temperature through the hot cylinder 9 to increase or decrease the moisture detection rate PW of the warp yarn. In addition, in the case of increasing or decreasing the moisture detection rate of the warp yarns, the skeining pressure of the skein roll 5, the immersion amount of the immersion roll 4 and the drying temperature of the hot cylinder 9 can all be adjusted. Choose multiple numbers, or adjust any number individually. In this embodiment, the goal of PW is to keep within the allowable range. If the current situation of pw is within this range, the twisting pressure of the unwinding roller 5 does not need to be changed. The “allowable range” referred to here generally refers to the range of errors. If there is no error, the target 値 of PW is set to a specific 値, and the allowable range is not set. Similarly, if there is no error at all, the operations of blocks 3 and 5 can also be omitted. However, when considering the various conditions or conditions of the sizing machine, -18- 507039 5. Description of the invention (17) This "capacity range" may also include many substantial numbers outside the error range. In addition, in this embodiment, Because the heating cylinder 9 for drying the warp yarn 8 is provided between the wetting device 2 and the sizing device 10, the formula (1 2) is used to obtain the moisture detection rate PW of the warp yarn before sizing. If this is not set, In the case of a drying device, it is better to use the formula (1 1) to obtain the moisture detection rate PW of the warp yarns of the humidifying device. Furthermore, although the input / output device 17 generally displays the concentration of the slurry 11 calculated by the program device 16, all other 値 input to the program device 16 and all the 値 calculated here can also be simultaneously show.
