201008859 六、發明說明： 【發明所屬之技術領域】 本發明係關於聚合物膜之捲取方法及其裝置。 【先前技術】 用於液晶顯示器（LCD)用偏光板保護膜等之聚合物 膜’ 一般係由溶液製膜法所製造。在使用此溶液製膜法製 造聚合物膜之薄薄膜製造線中，將例如，醋酸纖維等之聚 合物與可塑劑、UV吸收劑、滑劑等之各種添加劑一起溶解 0 於溶媒中而調配成塗布液（dope)。並將此塗布液延流於作 爲支撐體之滾筒（drum)或帶（band)上，在具備自身支撐性時 予以剝離。接著，一面由通行輥輸送被剝離之軟膜一面以 熱風進行乾燥，藉以形成聚合物膜（以下稱爲薄膜）。 薄膜被連續地輸送至設於薄膜製造線的下游側之薄膜 捲取裝置，在該處依照用途及設備能力等，以數百米或數 千米之長度，捲取於由樹脂、金屬、木材、厚紙等所製作 的圓筒狀捲芯上。另外，在捲成捲筒狀之膜輥的形態下， Q 被適宜捆包而成爲製品形態。此時，隨著薄薄膜製造線之 生產能力的提高，當在薄膜捲取裝置中昇高薄膜之捲取速 度時，氣體會與薄膜一起被捲入。當氣體被捲入膜輥時， 會形成在膜之層間具有不均勻空氣厚度的膜輥。藉此，會 產生局部之黑筋狀（以下稱爲黑筋故障）。 爲了避免此黑筋故障，熟知一種方法（例如，專利文獻 1)，其依照薄膜之捲取速度及厚度、膜輥之捲徑等來改變 薄膜之捲取張力（tension)，並將加壓輥抵接於膜輥的周 面，以強制性地排除薄膜捲取時所捲入的氣體，防止產生 -4- 201008859 空氣之捲入所造成的品質故障。 另外，熟知一種方法（例如，專利文獻2)，其爲了防止 膜輥之捲取偏差，預先於薄膜之寬度方向的兩端部附設由 微小凹凸所構成之滾紋，並將其捲取於捲芯上。 [專利文獻1]2002-220 1 43號公報 [專利文獻2]2002-25 5409號公報 【發明内容】 (發明所欲解決之課題） 0 然而，專利文獻2中，當藉由加壓輥或吹氣一面將薄 膜按壓於輥周面一面將兩端部附設滾紋之薄膜不斷地捲取 於捲芯上時，因實施了滾紋加工之兩端部（以下，稱爲耳部） 與未實施滾紋加工的中央部（以下，稱爲製品區域）之間的 微小膜厚差不斷地累積，會在膜輥之外周面的薄膜上之寬 度方向的兩側緣部附近，出現沿大致周方向之階梯差。 在一面將薄膜按壓於出現此種階梯差的膜輥上一面捲 取於膜輥上的情況，因在耳部實施有滾紋加工，所以，耳 〇 部比製品區域更爲隆起。因此，薄膜之耳部會先按壓於膜 輥上。然後，薄膜上之寬度方向的製品區域才被按壓於膜 輥上。 藉由此構成，雖可強制性地排除薄膜捲取時所捲入的 空氣，但在按壓薄膜上之寬度方向的製品區域時，因耳部 已被按壓，所以，在捲取薄膜時，無法朝耳部方向排除被 捲入製品區域的空氣，可能會殘留於製品區域中。結果在 膜輥中之膜層間，於薄膜之製品區域產生空氣厚度，藉此， 恐有產生黑筋故障之虞。 201008859 本發明係用以解決上述問題者，其目的在於提供一種 聚合物膜之捲取方法及其裝置，其防止在膜輥中之膜層 間’在薄膜之製品區域產生空氣厚度。 (解決課題之手段） 本發明之聚合物膜之捲取裝置，其特徵爲具備：捲取 機本體’使捲芯朝聚合物膜之捲取方向旋轉，將該聚合物 膜捲取於該捲芯上；第1送風部，從延設於該聚合物膜之 寬度方向上的吹出口，對捲取於該捲芯上之該聚合物膜的 0 除了該聚合物膜之寬度方向的兩端部以外的製品區域噴吹 氣體；及第2送風部，相對該第1送風部而配置於該聚合 物膜之捲取方向的下游側，對該聚合物膜之寬度方向的該 兩端部噴吹氣體。 該第1及第2送風部係以朝與該捲取方向相反之側噴 吹氣體爲較佳。該第2送風部係以使該氣體之吹出方向與 該聚合物膜的寬度方向交叉’並朝斜外方向吹出氣體爲較 佳。 Q 該第2送風部以具備：送風管’具有延設於該聚合物 膜的寬度方向上的吹出口；及送風管方向改變部，使該導 管旋轉移位，用以改變氣體吹出方向爲較佳。以在該聚合 物膜之捲取位置具備加壓輥（lay-onroll)或第3送風部，用 以將該聚合物膜朝捲心方向按壓爲較佳。以該聚合物膜在 該兩端部具有經實施滾紋（knur ling)加工之耳部爲較佳。 本發明之聚合物膜之捲取方法，其特徵爲具備：薄膜 捲取步驟，使捲芯朝聚合物膜之捲取方向旋轉，將該聚合 物膜捲取於該捲芯上；第1送風步驟，在將該聚合物膜捲 201008859 取於該捲芯之期間，從延設於該聚合物膜之寬度 吹出口，對除了該聚合物膜之寬度方向的兩端部 品區域噴吹氣體；及第2送風步驟，對該聚合物 方向的該兩端部噴吹氣體。 以該聚合物膜在兩端部具有經實施了滾紋加 爲較佳。 (發明效果） 根據本發明，在薄膜捲取中，對製品區域進 Q 膜之第1送風，用以對膜輥進行氣壓。藉此，在 間，將殘留於製品區域之氣體朝處於薄膜的寬度 之耳部擠出。接著，對除了第1送風後之製品區 進行噴吹薄膜之第2送風，在膜輥與捲取於此膜 層的薄膜之間，將殘留於耳部之氣體，確實地排 之外側。藉此，可確實將藉由第1送風的氣壓而 之殘餘氣體排出至膜輥外，所以，可抑制殘留氣 之黑筋故障的產生。尤其是在具有薄膜寬度方向 Q 施以滾紋加工之耳部的薄膜中，在滾紋加工部分 壓之氣體排除受到阻礙，而多會殘留於膜輥內， 排除此殘餘氣體，進行薄膜之捲取。 【實施方式】 如第1圖所示，捲取裝置10係在輸送薄膜 方向，配置於薄薄膜製造線12的下游側。在薄薄 12與捲取裝置10之間，依序設有滾紋賦予輥14 斷裝置15。薄薄膜製造線12係將包含作爲聚合 酸纖維（以下，稱爲TAC)與溶媒的塗布液延流於 方向上的 以外的製 膜之寬度 工之耳部 行噴吹薄 膜輥之層 方向外側 域的耳部 輥之最上 出於膜輥 無法去除 體所引起 兩端部被 ，利用氣 可確實地 11之輸送 膜製造線 及耳部切 物之三醋 支撐體上 201008859 而製作延流膜’然後剝下此延流膜，並將延流膜內含有之 溶媒蒸發’製造長尺狀之薄膜11。然後，薄薄膜製造線12 上所製造的薄膜11’通過滾紋賦予輥14及耳部切斷裝置 15而輸送至捲取裝置1〇。 如第2圖及第3圖所示’滾紋賦予輥14係於長尺狀之 薄膜11的寬度方向之耳部Ua，藉由浮雕（emboss)加工等 設置複數個微小的凸部1 6。此凸部1 6係設爲例如，圓錐 台形狀。但凸部16之形狀不限定於圓錐台形狀，亦可採用 0 例如’角錐形、圓球形、波形、格子形、不定形等的集合 體等的各種形狀。 如第1圖所示’耳部切斷裝置15係用以切斷除去薄膜 11之耳部的多餘部分。此耳部切斷裝置15上連接有未圖 示之粉碎機。由耳部切斷裝置15所切斷之耳部，藉由送風 輸送至粉碎機而被粉碎，然後，作爲塗布液等之原料被再 利用。又，耳部切斷裝置15與滾紋賦予輥14亦可設置於 同一裝置內。另外，亦可於耳部切斷後賦予滾紋。 〇 捲取裝置10係旋轉臂（turret arm)方式，具有旋轉臂 21、保持台22、氣壓部23、捲取張力調節部24、及控制 器25。旋轉臂21係可旋轉地安裝於保持台22上。在旋轉 臂21之兩端部安裝有安裝軸26，在此安裝軸26上設定有 捲芯27。安裝軸26連結於馬達28。馬達28係使捲芯27 朝箭頭A所示之薄膜的捲取方向旋轉，將薄膜11捲取於捲 芯27上。 在旋轉臂21右側之薄膜Π的捲取位置PR，將薄膜捲 取於旋轉臂21之一方的安裝軸26上所設定的捲芯27上 201008859 時，在處於另一方之捲芯交換位置的安裝軸26上，進行膜 輥29之取出與新捲芯30之設定。 旋轉臂21係藉由未圖示之臂旋轉機構進行每次180度 的間歇旋轉。於是，當一方之捲芯27上被捲取了僅能捲取 長度量之薄膜11而成爲滿捲時，旋轉臂21依時針方向旋 轉180度，將空的捲芯30設定於捲取位置PR，而能將薄 膜連續地捲取於空的捲芯30上。又，來自滿捲之膜輥29 的薄膜切斷、及切斷後之薄膜的對新的捲芯30之捲繞，係 0 由另設於捲取裝置10之薄膜捲繞切斷裝置（省略圖示）所進 行。 安裝軸26係使捲芯27朝捲取方向A旋轉，將薄膜11 以捲筒狀捲繞於捲芯27上。此時，藉由氣壓部23對捲取 位置PR之薄膜11噴吹氣體，防止因薄膜11之高速捲取所 產生之隨同氣體的捲入》 氣壓部23具備第1送風頭部（第1送風部）31及第2送 風頭部（第2送風部）32。第1送風頭部31具有延設於薄膜 Q 寬度方向上的細縫狀的吹出口 33，且連接於送風機34。如 第2圖所示，藉由此第1送風頭部31，對除了薄膜寬度方 向之耳部11a以外的製品區域lib噴吹氣體，將滯留於膜 輥29之層間的製品區域Ub中之氣體，從製品區域llb朝 耳部1 1 a擠出。 如第1圖所示，此第1送風頭部31係以吹氣方向朝與 捲取方向A相反方向的方式，對以捲芯27爲中心之放射線 L1傾斜一個傾斜角<91之角度而進行安裝。以爲〇度 以上、45度以下爲較佳。又，以0 1爲15度以上、3〇度 201008859 以下爲更佳。另外，第1送風頭部31係以於捲取位置PR 噴吹氣體之位置關係，配置於捲芯27之周圍。又，吹氣方 向亦能以朝向捲取方向A之方式對放射線L 1傾斜地安裝 此第1送風頭部31。 第2送風頭部32係沿捲取方向A配置於第1送風頭部 3 1的更下游側，例如、以捲芯27爲中心對薄膜捲取方向A 偏移30度左右之位置。又，此偏移量不限定於本實施形 態，亦可適宜地變更，亦可配置於偏移20度左右之位置。 φ 如第4圖所示’第2送風頭部32具有延設於薄膜寬度 方向上的細縫狀的吹出口 35，且配置於薄膜寬度方向的兩 端部。吹出口 35之寬度係與處於膜輥29之周面的薄膜u 之耳部11a的寬度大致相同。另外，第1送風頭部31之吹 出口 33的寬度，係與製品區域lib的寬度大致相同。又， 耳部11a之寬度係膜輥29之寬度的1 0%以上、20%以下， 製品區域1 1 b之寬度係膜輥2 9之寬度的8 0 %以上、9 0 %以 下。於是，如第1圖所示，在第2送風頭部32上亦連接有 Q 送風機34。藉由此第2送風頭部32,對耳部lla噴吹氣體。 藉此’藉由來自第2送風頭部32的氣體，將從膜輥29之 層間的製品區域lib中被擠出，但被耳部iia阻擋而滯留 之氣體，確實地排出於膜輥29外。因此，與習知方式從― 個吹出口吹出氣體之氣壓部不同，可確實地將滯留於耳部 11a之氣體排出於膜輥29外。 此第2送風頭部32係以吹氣方向朝與捲取方向a相反 方向的方式’對以捲芯27爲中心之放射線L1傾斜一個傾 斜角Θ2之角度而進行安裝。以02爲〇度以上、45度以 -10- 201008859 下爲較佳。又’以02爲15度以上、30度以下爲更佳。此 傾斜角02係設定爲與第1送風頭部31之傾斜角01相同 或更大。藉由設定爲比0 1更大，可確實地排出耳部lla 之氣體。又，吹氣方向亦能以朝向捲取方向A之方式傾斜， 來安裝第1送風頭部31。 另外，控制器25係控制第1、第2送風頭部3 1、32 所送風之速度及風向。作爲氣體之送風源的送風機34，係 在控制器25之控制下，產生預定壓力之氣體。於是，由此 0 送風機34所產生之氣體，透過未圖示之氣體配管，從第卜 第2送風頭部31、32之吹出口 33、35，以預定之氣體壓 力（噴吹壓力）將氣體噴吹於膜輥29之周面。 第1、第2送風頭部31、32係固定於安裝支架36上。 安裝支架36係設成可於膜輥29之直徑方向作移位，藉由 位移機構37來因應於薄膜之捲徑的增加作移動，使吹出口 33、35與膜輥29之最外周面的距離保持一定。 位移機構37係在控制器25之控制下，使安裝支架36 Q 隨著捲取半徑R1的增大而作移動，使得第1、第2送風頭 部31、32與薄膜11表面之距離保持一定。作爲此位移機 構37,只要爲可移動安裝支架36者，可採用任意之機構。 捲取張力調節部24具備跳動機構41、張力測定用感 測器42、及脈衝產生器43。跳動機構41具有導輥44、45 及跳動輥46，在導輥44、45之間使跳動輥46昇降。張力 測定用感測器42係安裝於導輥44上，用以測定薄膜捲取 時之張力。此測定之張力信號被輸送至控制器25。脈衝產 生器43係根據導輥47之旋轉移位而產生脈衝，並將產生 -11- 201008859 之脈衝輸送至控制器25。 控制器25係控制捲取裝置10，將薄膜11捲取於捲芯 27上。首先，控制器25藉由計數脈衝產生器43所產生之 脈衝，檢測薄膜11之捲取長度。然後，以捲取張力成爲預 定値的方式控制昇降機構。捲取張力之調節係根據來自張 力測定用感測器42之張力信號而使跳動輥46移位所進 行。例如，在張力高之情況，使跳動輥46下降，在張力低 的情況，相反地使跳動輥46上昇，將張力控制在一定範圍 Q 內。藉此，可根據捲取長度，由最適當之張力進行薄膜11 之捲取。在本實施形態中，雖爲隨著捲取長度增長，捲取 半徑R1亦增大，而使捲取張力降低的模式，但並不限定於 此’針對此捲取長度與捲取張力的模式，亦可適宜地採用 周知之模式來變更。 控制器25除了進行上述捲取張力之調節外，亦可進行 旋轉臂21之旋轉控制、及對未圖示之薄膜捲繞切斷裝置輸 出切斷薄膜及開始捲取信號等。 Ο 其次’說明本實施形態之作用。如第1圖所示，薄薄 膜製造線12係藉由溶液製膜法來製造薄膜n，並將薄膜 11輸送至滾紋賦予輥14。滾紋賦予輥14係對薄膜之耳部 H a(參照第2圖）賦予預定的滾紋。耳部切斷裝置I〗—面 殘留下經賦予滾紋之耳部11a，一面切斷除去薄膜U之兩 緣的多餘耳部。然後，薄膜U被輸送至捲取裝置1〇。 在捲取裝置10’將捲芯27設定於旋轉臂21之兩端部。 未圖示之捲繞裝置，在將由薄薄膜製造線12所製造的薄膜 11的前端捲繞於捲芯27後，控制器25以開始薄膜U之 -12- 201008859 捲取時的捲取張力成爲預定値的方式來驅動跳動機構41。 接著，控制器25驅動馬達28，以預定之捲取速度開始薄 膜11之捲取。捲取張力可依製造條件適宜決定。例如，在 薄膜11之捲取速度爲l〇〇m/分、薄膜11之厚度爲80;/m、 薄膜11之寬度爲1 340mm、薄膜11之捲取全長爲4000米 之情況，將薄膜捲取開始時之捲取張力設定爲41 0N，並將 薄膜捲取結束時之捲取張力設定爲35 ON。 然後，控制器25在薄膜11之捲取開始之後，根據來 φ 自脈衝產生器43的脈衝信號，計算出膜輥29之捲取半徑 R1。於是控制器25根據此捲取半徑R1來驅動位移機構 37，使得第1、第2送風頭部31、32之吹出口 33、35中 的最靠近膜輥29之周面的端部與膜輥29的周面之間的距 離，在預定範圍內保持爲大致一定的値。 當膜輥29之捲取半徑R1達到預定的値而結束薄膜11 之捲取後，則停止送風機34之驅動，並驅動位移機構37, 而使第1、第2送風頭部31、32退避至預定位置》接著， 採用薄膜切割機（未圖示）等，在預定位置切斷薄膜11，並 藉由未圖示之捲繞裝置將切斷之薄膜11的前端捲取於空 的捲芯上。然後，使旋轉臂21僅旋轉預定的角度，將此捲 芯設定於捲取位置，並將捲取結束之膜輥29設定於取出位 置。在取出位置上取出膜輥29之後，設定空的捲芯30。 在開始薄膜11之捲取時，控制器25驅動送風機34, 以產生預定壓力之氣體，並對捲取於膜輥29上之薄膜11 的捲取位置PR附近的表面，以例如、壓力2kPa以上、lOkPa 以下噴吹氣體。藉此，薄膜11 一面按壓於捲芯27或膜輥 -13- 201008859 29上一面被捲取。雖該氣體之噴吹係以與薄膜u的捲取 開始同時進行爲較佳，但除此之外，亦可在捲取穩定之階 段進行氣體噴吹。藉由氣體之噴吹，無需使用加壓輥，能 以非接觸之方式除去捲入膜輥29中的氣體。 又’爲了進行風向之調整，亦可將未圖示之風扇設置 於第1、第2送風頭部31、32之吹出口 33、35。藉由設置 風扇，可自由變動風向地將氣體朝膜輥29之周面送出，所 以，可有效地對重疊於膜輥29之薄膜施力，可更爲有效地 〇 去除捲入製品區域lib及耳部11a中的氣體。 另外’如第5圖所示，亦可設置旋轉移位機構51,其 在吹出口 35之氣體吹出方向與薄膜之寬度方向交叉的方 向，以朝向膜輥29之外側的方式，使第2送風頭部32之 姿勢旋轉。在此情況時，藉由旋轉軸52可旋轉自由地安裝 第2送風頭部32，在與薄膜面平行之面內使第2送風頭部 32自由旋轉，利用旋轉移位機構51來改變第2送風頭部 32相對第1送風頭部31之傾斜角度，使得一對之第2送 〇 風頭部32成爲左右對稱之傾斜角度。 如第6圖所示，亦可採用單一送風頭部55來取代第1、 第2送風頭部31、32，單一送風頭部55係設有與第2送 風頭部32之吹出口對應的吹出口 53，及與第1送風頭部 31之吹出口對應的吹出口 54。藉由將多個送風頭部設成單 一送風頭部，可減少構成送風頭部之構件。 此外，控制器25係以從第1送風頭部31之中心，隨 著朝向膜輥29的寬度方向之端部而漸漸增大第丨送風頭部 31所送之風的風壓的方式進行控制爲較佳。在膜輥之中心 -14- 201008859 位置，使得用以移動殘留於膜輥之層間的氣體的力爲最 小，隨著從中心位置朝向外側，而漸漸增大該力，藉此可 更爲有效地去除滯留於中心位置之氣體。 又，以送風部所送風之風壓爲2kPa以上、l〇kPa以下 爲較佳。在低於2kPa時，無法獲得移動殘留於膜輥之層間 的氣體的效果。在比10kPa大之情況，氣體排出效果成爲 . 飽和狀態，因過大之送風而造成運行之損失，而不甚理想。 控制器25係計算出捲取半徑R1，並根據此捲取半徑 0 R1來驅動位移機構37，使得第1'第2送風頭部31、32 之吹出口與膜輥29的周面之間的距離，在預定範圍內保持 爲大致一定的値。以此距離爲3mm以上' 30mm以下爲較 佳，更以5mm以上、15mm以下爲特佳》 當膜輥29之捲取長度達到一定的値而結束薄膜11之 捲取後，則停止送風機34之驅動，並驅動位移機構37， 而使第1、第2送風頭部31' 32退避至預定位置。 其次，參照第7圖，說明第2實施形態。在此捲取裝 Q 置60中，取代第1實施形態中的氣壓部23(參照第1圖）， 在捲取位置PR附近設置第1氣壓部61。第1實施形態中 的氣壓部，配置於沿著捲取方向A、比捲取位置PR更下游 方向，具體而言，以配置於比捲取位置PR270度以上、330 度以下之位置爲較佳。稱此氣壓部爲第2氣壓部62。並對 與第1實施形態相同之構件，賦予相同的元件符號。第7 圖中，捲取張力調節部與第1實施形態相同，故而，省略 圖示及說明。 第1氣壓部61具有第3送風頭部（第3送風部）62、位 -15- .201008859 移機構63及送風機64。與第1實施形態之氣壓部相同， 第3送風頭部62具有延設於薄膜寬度方向上的細縫狀的吹 出口 65，且連接於送風機64。藉由此第3送風頭部62沿 著薄膜寬度方向全面地噴吹氣體，將新捲繞之薄膜按壓於 膜輥29上。 位移機構63係在控制器25之控制下，以第3送風頭 部62之吹出口與膜輥29之周面平行的方式，使第3送風 頭部62隨著捲取半徑R1之增大而作水平移動，使得第3 φ 送風頭部62與薄膜11表面之距離保持爲一定。作爲此位 移機構63，只要爲可移動第3送風頭部62者，可採用任 意之機構。 可藉由第2氣壓部62更爲確實地排除由第1氣壓部 61未能完全排除之被捲入膜輥29的層間之氣體。此外， 在從捲取位置PR開始沿捲取方向A，且比配置有第1氣壓 部61之位置，在270度以上、330度以下的範圍內偏向下 游方向，設有第2氣壓部62的情況，第2氣壓部62係在 0 第1氣壓部61之附近，且沿捲取方向A之相反方向配置於 比捲取位置PR更上游處。藉由此配置，可有效地排除隨同 正要進入捲取位置PR前之膜輥29的周面的氣體。藉由此 構成，可減少由第1氣壓部61捲入膜輥29之層間的氣體。 在將第2氣壓部62配置於從捲取位置PR開始沿捲取 方向A還要小2 70度之位置的情況，因不對正要進入捲取 位置PR前之膜輥29的周面噴吹氣體，所以，排除隨同的 風之效果減小。另外，在將第2氣壓部62配置於從捲取位 置PR開始沿捲取方向A還要大330度之位置的情況，因 -16- 201008859 太靠近第1氣壓部61，有可能會接觸薄膜11，而不甚理想。 又，亦可取代第1氣壓部61 ’而採用捲取時與薄膜接 觸之加壓輥。 在本實施形態中，雖以二軸之旋轉方式的捲取裝置爲 例進行了說明，但本發明並不限定於此，亦可採用三軸以 上之旋轉方式的捲取裝置。 由薄薄膜製造線12所製造的薄膜11，以在長度方向 (延流方向）至少爲100米以上爲較佳。另外，以薄膜11之 Q 寬度爲600mm以上爲較佳，以1400mm以上、2500mm以 下爲特佳。另外，本發明在比25 00mm還大的情況亦有效。 在製造薄膜11之厚度爲40 以上、60//m以下的薄膜 時，亦可應用本發明。 在上述實施形態中，雖說明了由溶液製膜方法所製造 之TAC膜的捲取方法及其裝置，但本發明並不限定於此， 亦可應用於TAC膜以外之聚合物膜等、或其他之聚合物膜 的捲取方法及其裝置。另外，該等之聚合物膜亦不限定於 Q 藉由溶液製膜方法所製造者，亦可爲藉由熔融製膜法等之 公知製造方法來製造的聚合物膜》 【圖式簡單說明】 第1圖爲顯示本發明之第1實施形態的捲取裝置之槪 要圖。

Description of the Invention: [Technical Field of the Invention] The present invention relates to a method and apparatus for winding a polymer film. [Prior Art] A polymer film 'for a polarizing plate protective film or the like for a liquid crystal display (LCD) is generally produced by a solution film forming method. In a thin film production line for producing a polymer film by using the solution film forming method, for example, a polymer such as cellulose acetate is dissolved in a solvent together with various additives such as a plasticizer, a UV absorber, and a slip agent to prepare a polymer. Coating solution (dope). This coating liquid is allowed to flow onto a drum or a belt as a support, and is peeled off when it has self-supporting properties. Next, the peeled soft film is conveyed by a passing roller while being dried by hot air to form a polymer film (hereinafter referred to as a film). The film is continuously conveyed to a film winding device provided on the downstream side of the film manufacturing line, where it is taken up in a length of several hundred meters or several kilometers in terms of use, equipment, etc., by resin, metal, wood On a cylindrical core made of thick paper or the like. Further, in the form of a film roll wound into a roll shape, Q is suitably bundled to form a product. At this time, as the production capacity of the thin film manufacturing line is increased, when the winding speed of the film is raised in the film winding device, the gas is entangled with the film. When the gas is drawn into the film roll, a film roll having a non-uniform air thickness between the layers of the film is formed. As a result, a local black rib (hereinafter referred to as black rib failure) is generated. In order to avoid this black rib failure, a method (for example, Patent Document 1) is known in which the winding tension of the film is changed in accordance with the winding speed and thickness of the film, the winding diameter of the film roll, and the like, and the pressure roller is pressed. Abutting against the circumferential surface of the film roll to forcibly remove the gas entrapped during film winding, preventing the quality failure caused by the entrapment of air in -4-201008859. In addition, a method (for example, Patent Document 2) is known in which a roll formed of minute irregularities is attached to both end portions in the width direction of the film in order to prevent the film roll from being misaligned, and is wound up in a roll. On the core. [Patent Document 1] JP-A-2002-220, No. 1, No. 2002-A No. 2002-A No. 2002-A No. 2002-A No. 2002-25 When the film is pressed against the circumferential surface of the roll while blowing the film, and the film having the knurls at both ends is continuously wound on the core, the both ends of the embossing process (hereinafter referred to as ear) and the The difference in the thickness of the film between the center portions (hereinafter referred to as the product regions) where the embossing is performed is continuously accumulated, and appears in the vicinity of both side edges in the width direction on the film on the outer peripheral surface of the film roll. The difference in direction. When the film is pressed onto the film roll while pressing the film on the film roll having such a step, the ear portion is embossed, so that the ear portion is raised more than the product portion. Therefore, the ear of the film is first pressed against the film roll. Then, the product area in the width direction on the film is pressed against the film roll. According to this configuration, it is possible to forcibly exclude the air entrapped during the film winding, but when the product region in the width direction of the film is pressed, since the ear portion is pressed, it is impossible to wind up the film. Excluding air trapped in the product area in the direction of the ear may remain in the product area. As a result, an air thickness is generated between the film layers in the film roll in the product area of the film, whereby the black rib failure may occur. 201008859 The present invention has been made to solve the above problems, and an object thereof is to provide a method of winding a polymer film and an apparatus thereof for preventing an air thickness from being generated in a film region of a film in a film roll. (Means for Solving the Problem) The winding device for a polymer film according to the present invention is characterized in that the winding machine main body 'rotates the winding core toward the winding direction of the polymer film, and winds the polymer film on the roll a first air blowing portion, from the air outlet extending in the width direction of the polymer film, the 0 of the polymer film wound on the core, except for the width direction of the polymer film a blowing gas in a product region other than the portion; and a second air blowing portion disposed on a downstream side of the winding direction of the polymer film with respect to the first air blowing portion, and spraying the both end portions in the width direction of the polymer film Blowing gas. It is preferable that the first and second air blowing portions blow the gas toward the side opposite to the winding direction. The second air blowing portion is preferably such that the gas blowing direction intersects the width direction of the polymer film and the gas is blown outward in the oblique direction. The second air blowing unit includes: a blowing duct having a blowing port extending in a width direction of the polymer film; and a blowing duct direction changing unit for rotating the duct to change a gas blowing direction. good. It is preferable to provide a lay-on roll or a third blower at the winding position of the polymer film, and to press the polymer film in the direction of the core. It is preferable that the polymer film has an ear portion subjected to knurling processing at both end portions. A method for winding up a polymer film according to the present invention, comprising: a film winding step of rotating a winding core toward a winding direction of the polymer film, and winding the polymer film on the winding core; the first air supply In the step of taking the polymer film roll 201008859 from the core, the gas is blown from the width of the polymer film, and the gas is sprayed on both end portions of the polymer film in the width direction; In the second blowing step, gas is blown to the both end portions in the polymer direction. It is preferred that the polymer film is embossed at both ends. (Effect of the Invention) According to the present invention, in the film winding, the first air blow is applied to the product region to pressurize the film roll. Thereby, the gas remaining in the product region is extruded toward the ear portion at the width of the film. Then, the second air blow of the film is sprayed on the product area except the first air blow, and the gas remaining in the ear portion is reliably disposed outside the film roll and the film wound around the film layer. Thereby, the residual gas by the air pressure of the first air blow can be surely discharged to the outside of the film roll, so that the occurrence of the black rib failure of the residual gas can be suppressed. In particular, in the film having the embossed ear portion in the film width direction Q, the gas removal in the embossing portion is hindered, and the residual gas remains in the film roll, and the residual gas is removed to carry out the film roll. take. [Embodiment] As shown in Fig. 1, the winding device 10 is disposed on the downstream side of the thin film production line 12 in the direction of transporting the film. Between the thin film 12 and the winding device 10, a knurling applying roller 14 breaking device 15 is sequentially provided. In the thin film production line 12, the coating liquid containing the polymerized acid fiber (hereinafter referred to as TAC) and the solvent is allowed to flow in the direction other than the width of the film. At the top of the ear roll, the end of the film roll can not be removed, and the gas can be used to make the film and the three vinegar support of the ear cut on the 201008859 to make the throttling film. The film is peeled off and the solvent contained in the film is evaporated to produce a long-length film 11. Then, the film 11' produced on the thin film production line 12 is conveyed to the winding device 1 by the embossing roller 14 and the ear cutting device 15. As shown in Fig. 2 and Fig. 3, the embossing roller 14 is attached to the ear portion Ua in the width direction of the long-length film 11, and a plurality of minute projections 16 are provided by embossing or the like. This convex portion 16 is, for example, a truncated cone shape. However, the shape of the convex portion 16 is not limited to the shape of a truncated cone, and various shapes such as an aggregate such as a 'corner cone shape, a spherical shape, a wave shape, a lattice shape, and an indefinite shape may be employed. The ear cutting device 15 is used to cut off the excess portion of the ear portion of the film 11 as shown in Fig. 1. A pulverizer (not shown) is connected to the ear cutting device 15. The ear portion cut by the ear cutting device 15 is pulverized by air supply to the pulverizer, and then reused as a material for the coating liquid or the like. Further, the ear cutting device 15 and the embossing roller 14 may be provided in the same device. In addition, the embossing can be imparted after the ear is cut. The winding device 10 is a turret arm type, and includes a rotating arm 21, a holding table 22, a pneumatic portion 23, a take-up tension adjusting portion 24, and a controller 25. The rotating arm 21 is rotatably mounted on the holding table 22. A mounting shaft 26 is attached to both ends of the rotating arm 21, and a winding core 27 is set on the mounting shaft 26. The mounting shaft 26 is coupled to the motor 28. The motor 28 rotates the winding core 27 in the winding direction of the film indicated by the arrow A, and winds the film 11 onto the winding core 27. At the winding position PR of the film bundle on the right side of the rotating arm 21, when the film is taken up on the winding core 27 set on the mounting shaft 26 of one of the rotating arms 21, the mounting is performed at the other core exchange position. On the shaft 26, the take-up of the film roll 29 and the setting of the new core 30 are performed. The rotating arm 21 is intermittently rotated by 180 degrees each time by an arm rotating mechanism (not shown). Then, when one of the winding cores 27 is wound up and the film 11 of the length can be wound up to be fully wound, the rotating arm 21 is rotated by 180 degrees in the clockwise direction, and the empty winding core 30 is set at the winding position PR. The film can be continuously wound onto the empty core 30. Further, the film from the full roll of the film roll 29 and the winding of the film after the cutting to the new core 30 are made of a film winding and cutting device provided separately from the winding device 10 (omitted from the drawing) Show). The mounting shaft 26 rotates the winding core 27 in the winding direction A, and winds the film 11 on the winding core 27 in a roll shape. At this time, the air pressure portion 23 blows the gas to the film 11 at the winding position PR to prevent the accompanying gas from being caught by the high-speed winding of the film 11. The air pressure portion 23 is provided with the first air blowing head (the first air blowing head) Part 31 and the second air blowing head (second air blowing unit) 32. The first air blowing head 31 has a slit-shaped air outlet 33 extending in the width direction of the film Q, and is connected to the air blower 34. As shown in Fig. 2, the gas is blown to the product region lib other than the ear portion 11a in the film width direction by the first air blowing head 31, and the gas remaining in the product region Ub between the layers of the film roll 29 is trapped. From the product area 11b, it is extruded toward the ear 1 1 a. As shown in Fig. 1, the first air blowing head 31 is inclined at an inclination angle < 91 angle with respect to the radiation L1 centering on the winding core 27 so that the blowing direction is opposite to the winding direction A. Install it. It is preferable that the temperature is above 45 degrees. Further, it is more preferable that 0 1 is 15 degrees or more and 3 degrees are 201008859 or less. Further, the first air blowing head 31 is disposed around the winding core 27 in a positional relationship of the blowing gas at the winding position PR. Further, in the blowing direction, the first air blowing head 31 can be attached to the radiation L 1 so as to be inclined toward the winding direction A. The second air blowing head 32 is disposed on the downstream side of the first air blowing head 31 in the winding direction A, and is, for example, shifted from the winding core 27 by about 30 degrees in the film winding direction A. Further, the offset amount is not limited to the present embodiment, and may be appropriately changed, or may be disposed at a position shifted by about 20 degrees. φ As shown in Fig. 4, the second air blowing head portion 32 has a slit-shaped air outlet 35 extending in the film width direction, and is disposed at both end portions in the film width direction. The width of the air outlet 35 is substantially the same as the width of the ear portion 11a of the film u on the circumferential surface of the film roll 29. Further, the width of the air outlet 33 of the first air blowing head 31 is substantially the same as the width of the product region lib. Further, the width of the ear portion 11a is 10% or more and 20% or less of the width of the film roll 29, and the width of the product portion 1 1b is 80% or more and 90% or less of the width of the film roll 2 9 . Then, as shown in Fig. 1, a Q blower 34 is also connected to the second air blowing head 32. The air is blown to the ear portion 11a by the second air blowing head portion 32. By this, the gas from the second air blowing head 32 is extruded from the product region lib between the layers of the film roll 29, but the gas trapped by the ear portion iia is surely discharged outside the film roll 29. . Therefore, unlike the gas pressure portion in which the gas is blown from the one outlet, the gas retained in the ear portion 11a can be surely discharged outside the film roll 29. The second air blowing head 32 is attached such that the radiation L1 centering on the winding core 27 is inclined at an inclination angle Θ2 in such a manner that the blowing direction is opposite to the winding direction a. It is better to use 02 for more than 〇 and 45 degrees for -10- 201008859. Further, it is more preferable that 02 is 15 degrees or more and 30 degrees or less. This inclination angle 02 is set to be the same as or larger than the inclination angle 01 of the first air blowing head 31. By setting it to be larger than 0 1, the gas of the ear portion 11a can be surely discharged. Further, the first blowing head 31 can be attached to the blowing direction so as to be inclined toward the winding direction A. Further, the controller 25 controls the speed and the wind direction of the air blown by the first and second air blowing heads 3 1 and 32. The blower 34, which is a supply source of the gas, is a gas of a predetermined pressure under the control of the controller 25. Then, the gas generated by the zero blower 34 passes through the gas pipe (not shown), and the gas is supplied from the air outlets 33 and 35 of the second air blowing heads 31 and 32 at a predetermined gas pressure (injection pressure). It is sprayed on the circumferential surface of the film roll 29. The first and second air blowing heads 31 and 32 are fixed to the mounting bracket 36. The mounting bracket 36 is configured to be displaceable in the diameter direction of the film roll 29, and is moved by the displacement mechanism 37 in response to an increase in the winding diameter of the film, so that the blowout ports 33, 35 and the outermost peripheral surface of the film roll 29 are The distance remains certain. The displacement mechanism 37 is moved by the controller 25 to move the mounting bracket 36 Q as the take-up radius R1 increases, so that the distance between the first and second air blowing heads 31, 32 and the surface of the film 11 is kept constant. . As the displacement mechanism 37, any mechanism can be employed as long as it is the movable mounting bracket 36. The take-up tension adjusting unit 24 includes a pulsating mechanism 41, a tension measuring sensor 42, and a pulse generator 43. The dancer mechanism 41 has guide rollers 44 and 45 and a dancer roller 46, and the dancer roller 46 is moved up and down between the guide rollers 44 and 45. The tension measuring sensor 42 is attached to the guide roller 44 for measuring the tension at the time of film winding. The measured tension signal is sent to the controller 25. The pulse generator 43 generates a pulse in accordance with the rotational displacement of the guide roller 47, and supplies a pulse of -11 - 201008859 to the controller 25. The controller 25 controls the take-up device 10 to wind the film 11 onto the winding core 27. First, the controller 25 detects the winding length of the film 11 by counting the pulses generated by the pulse generator 43. Then, the elevating mechanism is controlled in such a manner that the take-up tension becomes a predetermined enthalpy. The adjustment of the take-up tension is performed by shifting the dancer roller 46 based on the tension signal from the tension measuring sensor 42. For example, when the tension is high, the dancer roller 46 is lowered, and when the tension is low, the dancer roller 46 is reversely raised to control the tension within a certain range Q. Thereby, the film 11 can be taken up by the most appropriate tension according to the winding length. In the present embodiment, the winding radius R1 is increased as the winding length is increased, and the winding tension is lowered. However, the present invention is not limited to the mode in which the winding length and the winding tension are applied. It can also be appropriately changed using a well-known mode. In addition to the adjustment of the winding tension, the controller 25 can also perform rotation control of the rotating arm 21, and output a cut film and start a winding signal to a film winding and cutting device (not shown). Ο Next, the role of this embodiment will be described. As shown in Fig. 1, the thin film production line 12 is produced by a solution film forming method, and the film 11 is conveyed to the embossing roller 14. The embossing roller 14 imparts a predetermined embossing to the ear portion H a of the film (see Fig. 2). Ear cutting device I - surface The remaining ear portion from which both edges of the film U are removed is cut while remaining the ear portion 11a to which the knurl is applied. Then, the film U is conveyed to the take-up device 1A. The winding core 27 is set at both ends of the rotating arm 21 in the winding device 10'. In the winding device (not shown), after the leading end of the film 11 produced by the thin film manufacturing line 12 is wound around the winding core 27, the controller 25 starts to take up the winding tension of the film U -12-201008859. The beating mechanism 41 is driven in a predetermined manner. Next, the controller 25 drives the motor 28 to start the winding of the film 11 at a predetermined take-up speed. The take-up tension can be appropriately determined depending on the manufacturing conditions. For example, when the film 11 has a take-up speed of 10 μm/min, the film 11 has a thickness of 80 μm/m, the film 11 has a width of 1 340 mm, and the film 11 has a full length of 4000 m, the film roll is used. The take-up tension at the start of the take-up was set to 41 0N, and the take-up tension at the end of film winding was set to 35 ON. Then, the controller 25 calculates the take-up radius R1 of the film roll 29 based on the pulse signal from the pulse generator 43 after the winding of the film 11 is started. Then, the controller 25 drives the displacement mechanism 37 based on the take-up radius R1 so that the end of the peripheral faces of the film rolls 29 of the first and second blower heads 31, 32 which are closest to the film roll 29 and the film roll The distance between the circumferential faces of 29 is kept substantially constant within a predetermined range. When the winding radius R1 of the film roll 29 reaches a predetermined enthalpy and the winding of the film 11 is completed, the driving of the blower 34 is stopped, and the displacement mechanism 37 is driven to retract the first and second air blowing heads 31, 32 to "Predetermined position" Next, the film 11 is cut at a predetermined position by a film cutter (not shown) or the like, and the leading end of the cut film 11 is taken up on an empty core by a winding device (not shown). . Then, the rotating arm 21 is rotated only by a predetermined angle, the winding core is set at the winding position, and the winding roller 29 is set at the take-out position. After the film roll 29 is taken out at the take-out position, the empty core 30 is set. At the start of winding of the film 11, the controller 25 drives the blower 34 to generate a gas of a predetermined pressure, and winds up the surface near the winding position PR of the film 11 on the film roll 29, for example, at a pressure of 2 kPa or more. , blowing gas below lOkPa. Thereby, the film 11 is taken up while being pressed against the winding core 27 or the film roll -13 - 201008859 29. Although the blowing of the gas is preferably carried out simultaneously with the start of winding of the film u, in addition to this, the gas injection may be performed at a stage where the winding is stable. The gas entrained in the film roll 29 can be removed in a non-contact manner by blowing of a gas without using a pressure roller. Further, in order to adjust the wind direction, a fan (not shown) may be provided in the air outlets 33 and 35 of the first and second air blowing heads 31 and 32. By providing a fan, the gas can be sent to the circumferential surface of the film roll 29 with freely varying wind direction. Therefore, the film superimposed on the film roll 29 can be effectively biased, and the wound product area lib can be removed more effectively. The gas in the ear 11a. Further, as shown in Fig. 5, a rotation shifting mechanism 51 may be provided which allows the second air supply to be directed toward the outside of the film roll 29 in a direction in which the gas blowing direction of the air outlet 35 intersects with the width direction of the film. The posture of the head 32 is rotated. In this case, the second air blowing head 32 is rotatably attached by the rotating shaft 52, and the second air blowing head 32 is freely rotated in a plane parallel to the film surface, and the second shifting mechanism 51 is used to change the second. The inclination angle of the air blowing head 32 with respect to the first air blowing head 31 is such that the pair of second hurricane heads 32 are inclined at right and left symmetry. As shown in Fig. 6, a single air blowing head 55 may be used instead of the first and second air blowing heads 31 and 32, and the single air blowing head 55 may be provided with a blowing corresponding to the air outlet of the second air blowing head 32. The outlet 53 and the air outlet 54 corresponding to the air outlet of the first air blowing head 31. By providing the plurality of air blowing heads as a single air blowing head, the members constituting the air blowing head can be reduced. Further, the controller 25 controls the wind pressure of the wind sent from the first air blowing head 31 gradually from the center of the first air blowing head 31 as the end portion in the width direction of the film roll 29 is gradually increased. It is better. At the center of the film roll -14 to 201008859, the force for moving the gas remaining between the layers of the film roll is minimized, and the force is gradually increased as it goes from the center position toward the outer side, thereby being more effective Remove the gas trapped in the center. Further, it is preferable that the wind pressure of the air blown by the air blowing portion is 2 kPa or more and 10 kPa or less. When it is less than 2 kPa, the effect of moving the gas remaining between the layers of the film roll cannot be obtained. In the case where it is larger than 10 kPa, the gas discharge effect becomes a saturated state, and the operation loss due to excessive air supply is not preferable. The controller 25 calculates the take-up radius R1 and drives the displacement mechanism 37 based on the take-up radius 0 R1 such that the air outlets of the first 'second air blowing heads 31, 32 and the circumferential surface of the film roll 29 are The distance is kept substantially constant within the predetermined range. The distance is preferably 3 mm or more and is preferably 30 mm or less, and more preferably 5 mm or more and 15 mm or less. When the winding length of the film roll 29 reaches a certain level and the winding of the film 11 is completed, the blower 34 is stopped. The displacement mechanism 37 is driven to drive the first and second air blowing heads 31' 32 to a predetermined position. Next, a second embodiment will be described with reference to Fig. 7. In the winding unit Q 60, the first air pressure portion 61 is provided in the vicinity of the winding position PR instead of the air pressure portion 23 (see Fig. 1) in the first embodiment. The air pressure portion in the first embodiment is disposed in the downstream direction along the winding direction A and the winding position PR. Specifically, it is preferably disposed at a position of 270 degrees or more and 330 degrees or less from the winding position PR. . This air pressure portion is referred to as a second air pressure portion 62. The same components are denoted by the same members as those of the first embodiment. In the seventh embodiment, the take-up tension adjusting portion is the same as that of the first embodiment, and thus the illustration and description thereof are omitted. The first air pressure portion 61 has a third air blowing head (third air blowing portion) 62, a position -15-.201008859 moving mechanism 63, and a blower 64. Similarly to the pneumatic portion of the first embodiment, the third air blowing head 62 has a slit-like outlet 65 extending in the width direction of the film, and is connected to the blower 64. By this third blowing head 62, the gas is blown in the entire width direction of the film, and the newly wound film is pressed against the film roll 29. The displacement mechanism 63 controls the third air blowing head 62 to increase in the winding radius R1 so that the air outlet of the third air blowing head 62 is parallel to the circumferential surface of the film roller 29 under the control of the controller 25. The horizontal movement is such that the distance between the third φ air blowing head 62 and the surface of the film 11 is kept constant. As the displacement mechanism 63, any mechanism can be employed as long as the third air blowing head 62 can be moved. The gas which is not completely excluded by the first air pressure portion 61 and which is wound between the layers of the film roll 29 can be more reliably excluded by the second air pressure portion 62. In addition, the second air pressure portion 62 is provided in the winding direction A from the winding position PR in the winding direction A and in the range of 270 degrees or more and 330 degrees or less from the position where the first air pressure portion 61 is disposed. In other words, the second air pressure portion 62 is disposed in the vicinity of the 0th air pressure portion 61 and is disposed upstream of the winding position PR in the opposite direction of the winding direction A. With this configuration, the gas accompanying the peripheral surface of the film roll 29 before entering the winding position PR can be effectively eliminated. According to this configuration, the gas that is caught between the layers of the film roll 29 by the first air pressure portion 61 can be reduced. When the second air pressure portion 62 is disposed at a position that is 2270 degrees smaller than the winding direction A from the winding position PR, the circumferential surface of the film roll 29 before entering the winding position PR is not blown. The gas, therefore, eliminates the effect of the accompanying wind. In addition, when the second air pressure portion 62 is disposed at a position that is 330 degrees larger than the winding direction A from the winding position PR, the light may be in contact with the film due to the fact that the −16-201008859 is too close to the first air pressure portion 61. 11, not ideal. Further, instead of the first pneumatic portion 61', a pressure roller that is in contact with the film at the time of winding may be used. In the present embodiment, the winding device of the two-axis rotation type has been described as an example. However, the present invention is not limited thereto, and a winding device of a three-axis or more rotation type may be employed. The film 11 produced by the thin film production line 12 is preferably at least 100 m in the longitudinal direction (extension direction). Further, the Q width of the film 11 is preferably 600 mm or more, and particularly preferably 1400 mm or more and 2500 mm or less. Further, the present invention is also effective in the case of being larger than 2,500 mm. The present invention can also be applied to the production of a film having a thickness of the film 11 of 40 or more and 60//m or less. In the above embodiment, the winding method and apparatus for the TAC film produced by the solution film forming method have been described. However, the present invention is not limited thereto, and may be applied to a polymer film other than the TAC film, or the like. Other coiling methods and devices for polymer films. Further, the polymer film is not limited to the case where Q is produced by a solution film forming method, and may be a polymer film produced by a known production method such as a melt film forming method.
