1243865 玖、發明說明： 發明所屬之技術領域： 本發明係關於一種紡絲機（spinning machine ) 之纖維束收集（c ο 11 e c t i n g，亦稱捲繞）裝置，特別是關於 一種紡絲機之纖維束收集裝置，依其配置，係在紡絲機框 之牽伸裝置（牽伸部）的上游側，用以收集以牽伸裝置所牽 伸之纖維束者。 先前技術： 習用技術中，日本第JP- 0 72 3 8 42,i.....在號專利案揭示有該 ^ 型之纖維束收集裝置，如第7圖所示，其係在形成牽伸裝 置之一對最終滾子6 1的下游側，設以一對裝有打孔護裙 62之輸送滾子63 ;並設有一吸氣裝置64，用以對打孔護 裙6 2之輸送表面施加吸氣。在此種纖維束收集裝置中，吸 氣之氣流係經由一護裙籠6 5所形成之一吸取溝而施加於 打孔護裙62之輸送表面，用以引導打孔護裙62。 同樣的，DE 1 970 8 4 1 0 A1號專利案亦爲一種纖維束收集 裝置，其中如第8圖所示，在一對構成牽伸裝置之最終滾 擊 子7 1的下游側，設以一對裝有形成纖維束輸送表面之打孔 護裙7 2的輸送滾子7 3 ;並設有一吸氣裝置7 4，用以把吸 氣氣流施加於打孔護裙7 2之輸送表面。此種裝置中，吸氣 氣流係經一護裙引導件7 5中所形成之一溝孔而施加於打 孔護裙72之輸送表面，用以引導打孔護裙72。又，張力 係以一引導構件76施加於打孔護裙72，此狀態時，該引 導構件係轉動者。 -6· 1243865 又，JP 1卜2 8 6 8 3 7 A案所揭示之纖維束收集裝置中，於 、 最終滾子之下游側及一牽伸裝置之底側上’設有一用以形 成具有一吸取裂縫之靜止滑動面的中空外型（hollow profile) (弓丨導筒），且其中設有一輸送用之皮帶，係圍繞該中空外 型作捲摺。此種裝置中，在頂側設有一鉗夾滾子，係被持 住而接觸該打孔皮帶，以揭示一鉗夾點。上述之鉗夾滾子 係介由一傳輸皮帶而由上述之最終滾子予以作驅動。除了 介由傳輸皮帶對該鉗夾滾子作驅動之構造外，該案亦揭示 一種經由一傳輸滾子接觸最終滾子之方式，而達成驅動功 · 效之構造。 較諸使用未裝設纖維束收集裝置之紡絲機紡絲所產生之 線（thread)，使用裝設有纖維束收集裝置之紡絲機經由紡絲 所產生之線，其對於產生絨毛（fluff)與線碎雜物（thread specks)之減少率可增至U%。但是，仍具有須進一步改進 之處。 此業行家均知，增加”絲絨（fleece，或稱絨頭）角度”將可 有效抑制絨毛之產生。但是，同樣的，此亦將產生斷線之 肇 虞，故就操作之觀點而言，實爲甚大缺點。上述所稱”絲絨 角度’’之含義係指由：連接於弧面（沿此弧面、已行經鉗夾 點之纖維束（（絲絨））係引導至抽出位置）之曲度中心的摺扇 形鋏板（segment)與鉗夾點；及連接於曲度中心之摺扇形鋏 板與用於纖維束F之抽出端等所作成之角度。 上述之纖維束收集裝置中，並未見揭橥增加絲絨角度可 抑制產生絨毛以改善品質之技術思想與實質作法。例如， 1243865 在JP-Ο 7-23 842 5 A號案中，如上所述，在第7圖中，纖維 束F係在送出滾輪對6 3之鉗夾點的下游側，以實質爲切線 之方向抽出，並未見有絲絨角度之增加。而在D E 1 9 7 0 8 4 1 0 A1案中，纖維束F亦係在送出齒輪對7 3之下游側，以實 質爲切線之方向抽出，亦無增加絲絨角度之考量。 發明內容： 本案發明人曾準備一具有正性增加絲絨角度之纖維束收 集裝置，並將此一纖維束收集裝置裝設於一紡絲機，且以 一高速影像照相機攝取由此種紡絲機之紡絲所得的線 φ (thread);再比較裝設傳統式纖維束收集裝置之紡絲機，其 紡絲所得之線等兩種狀況。結果發現，增加絲絨角度後， 線（纖維束）係成往復式並沿著送出滾輪對之鉗夾點上游側 的護裙作滾動；而絲絨角度較小之傳統式構造，線則係成 滑移狀之往復式移動。又，尙另遂行對於紡絲所得之線的 有毛程度（hairiness)與U%作計測。依所計測之結果得知， 兩種狀況中之U%均爲甚多，但就有毛程度（hairiness)而言 ，該種具有正性增加之絲絨角度的構造，則有極其優異之 鲁 表現。本案發明人即基於此種認知而完成本發明。 故，本發明之目的，係提供一種紡絲機之纖維束收集裝 置，其中較諸於使用單一構造之傳統裝置而言，本發明可 大幅抑制滅毛之產生’可改善線的品質。 爲了達成上述目的，依本發明之紡絲機的纖維束收集裝 置，係關於一種用以收集由紡絲機之牽伸部所牽伸之纖維 束的纖維束收集裝置，包括：一送出部，係設在牽伸部一 -8- 1243865 對最終送出滾輪之下游側，並設有一鉗夾滾子 動面之吸取部，該滑動面開設有吸取孔，係在 出部之鉗夾點作移動的上游側成延伸式之形成 出部之一可透氣護裙，當其接觸於該滑動面時 在纖維束移動方向中，該吸取部之下游側設有 ，該可透氣護裙係圍繞該捲摺構件作捲摺’因 絲絨角度者。 於本發明中，牽伸部所牽伸之纖維束，係由 一對最終送出滾子之下游側上的纖維束收集裝 ，並係以收集之狀態作移動，因此，比較未具 集裝置之紡絲機而言，可抑制絨毛之產生，亦 之耗費，並因而可改善線的品質。又，因捲摺 吸取部之下游側，並爲分離設置，故可增加絲 使抑制產生絨毛之功效增強，因而可更進一步 之產生，並因之而改善線的品質。當纖維束行 ，係朝向下游側作移動並承受加撚作用（twisth

2、一中間底部滾子J 3 、及一後方底部滾子14。前方底部滾子12係由〜形成機 架框之滾子架1 5支持在一預設之位置上，而中間與後方底 部滾子13與14係經由固定在滾子架15之支架1^與 的調節作支持，故可在縱長方向作位置之調整。支架13a 與1 4a係藉穿經滾子架i 5所形成之長孔的螺栓與螺帽（未 · 不）作固緊。一底部護裙1 6則係圍繞一底部張力器1 7與中 間底部滾子1 3作捲摺。 一前方頂部滾子1 9、一中間頂部滾子20、及一後方頂部 滾子2 1等，係介由頂部滾子支持構件之調節而以一加重臂 1 8分別的對應於該前方底部滾子1 2、中間底部滾子1 3、 及後方底部滾子1 4之位置作支持。頂部滾子1 9〜2 1之各 滾子係支持於Z -銘子單元中。前方底部滾子1 2及前方頂 部滾子1 9係構成牽伸裝置1 1之一對最終送出滾子。 鲁 加重臂1 8上配設有一桿件1 8 a，故可轉動成加壓位置與 釋放位置。如第1圖所示之狀況，即桿件1 8a係毗連於加 重臂1 8之框架1 8 b而成加壓位置時’則可保持爲閉鎖狀態 ，其中以加重臂1 8所支持之頂部滾子1 9〜2 1係處於加壓 位置（紡絲位置）而朝向底部滾子1 2、1 3及1 4作加壓。另 當桿件1 8 a自第1圖所示位置轉動至上方，即成釋放位置 ，則閉鎖狀態即解除。 1243865 如第1圖所示，一纖維束收集裝置3 0係配置在牽伸裝置 1 1之對最終輸送滾子的下游側。纖維束收集裝置3 0裝設 有一輸送部3 1、一作爲吸取部之吸取管3 2、一捲摺構件 33、及一可透氣護裙34。輸送部31係由：一底部鉗夾滾 子3 5 a ’其係形成在一轉動軸3 5上，該轉動軸則係平行於 前方底部滾子12;及一頂部鉗夾滾子31a，其係介由可透 氣護裙3 4之調節而對底部鉗夾滾子3 5 a作加壓等兩者所組 成。 如第2 a圖所示，此實施例之纖維束收集裝置3 0中，與 鲁 頂部滾子1 9〜2 1同樣的，頂部鉗夾滾子3 1 a係以加重臂 18介由一支持構件36(示於第1、3圖）之調節而支持於每 個錠子中。注意者，乃此實施例中，支持構件3 6係與前方 頂部滾子1 9之支持構件兩者爲一體形成。 另一方面，在纖維束收集裝置3 0之底側上，於牽伸裝置 1 1之兩個相互毗鄰滾子架1 5間所配置之半數錠子，亦即 ，本實施例爲4個錠子，係構成一組單元。在依機座之縱 長方向以預定間隔作配置之滾子架1 5的中間位置處，配置 馨 有一支持臂38(僅示於第2a圖，用以形成機座框），其配置 之狀況爲，其之底端係以一在機座之縱長方向上作延伸之 支持樑3 7作支持，並配置有一轉動軸3 5，係在滾子架1 5 與支持臂3 8間作支持。 如第2b圖所示，轉動軸3 5之長度係對應於複數之錠子 (本實施例中爲4個錠子）而作成，任何一端可固設以一軸 承3 9。軸承3 9係配裝於端部插塞4 0內，且，如第2 a圖 1243865 所示’端部插塞40係以設在滾子架1 5與支持臂3 8上之支 持部15a與3 8a予以支持於啣接部4〇a內，因之，轉動軸 3 5係在滾子架丨5與支持臂3 8兩者間作可轉動式之支持。 支持部1 5 a與3 8 a之形成方式，係可用以支持固定在相鄰 近之轉動軸3 5端部上的兩個端部插塞4 〇。 支持部1 5a係以固定在滾子架丨5之一塊狀物（bl〇ck)所形 成’並具有一啣接凹口，係在機座之前側上依傾斜方向朝 上作延伸。支持部3 8 a亦具有一啣接凹口，係在機座之前 側上依傾斜方向朝上作延伸。則具有—啣接部4〇a之端部 鲁 插塞4 0即可啣接於該等凹口，則，以一簡單之動作，即可 把支持部1 5 a、3 8 a按壓而卡入於啣接部4 〇 a中。 在轉動軸3 5縱長方向之中心處，一體形成有一齒輪4 ! 。如第3圖所示，前方底部滾子1 2在對向於齒輪4 1之位 置上，設有一齒輪部12a。又，嚙合於該齒輪部12a與齒輪 41之一中間齒輪43，係以一支持臂42作可轉動之支持， 該支持臂42之底部，與支持臂3 8同樣的，係固定於支持 樑37。亦即，前方底部滾子i 2之扭力係經齒輪部1 2a、中 鲁 間齒輪4 3、及齒輪4 1傳輸至轉動軸3 5。 如第1圖所示，在紡絲框（機）之機座中，用以作爲用於 纖維束收集裝置之吸取源（負壓源）的複數導管44，係依縱 長方向配置（對第1圖所示之平面成垂直方向）。複數導管 44係依紡絲機之機座的縱長方向作延伸。用於令各導管44 保持負壓之抽吸裝屢45係經管件46連接於各導管44。抽 吸裝置4 5係由風扇馬達所構成，其中風扇係以馬達4 7驅 1243865 動。如第1圖所示，導管44〜係配置在牽伸裝置11之上方 後側及在紡絲機機座之中心處，且抽吸裝置4 5亦均配設在 導管44之下方。吸取管32係經連接管48連接於導管44 ，故係平行於導管4 4作延伸。 吸取管與捲摺構件3 3之支持狀態亦爲，其等之端部 係與支持轉動軸3 5之一對端部插塞4 0作配套之啣接。吸 取管3 2具有一滑動面3 2b，該滑動面開設有複數裂縫形吸 取孔32a，該等吸取孔之位置，對纖維束（絲絨）F於底部鉗 夾滾子3 5 a之鉗夾點的運動方向而言，係朝上游側作沿伸 φ 配設。捲摺構件3 3具有一滑動面3 3 a，用以依滑動式引導 可透氣之護裙34。如第3、4a圖所示，對纖維束F之移動 方向而言，吸取管3 2係配設在底部鉗夾滾子3 5 a之鉗夾點 的上游側，而捲摺構件3 3則係配設在下游側。 吸取管32係構成爲可將可透氣之護裙34作引導而帶至 前方底部滾子1 2與前方頂部滾子1 9兩者鉗夾點之附近處 。而捲摺構件3 3之配置方式則爲，使鉗夾點及纖維束自鉗 夾點之下游側上之可透氣護裙3 4分開的位置兩者間之距 鲁 離L不小於5mm，而以8〜10mm最佳。捲摺構件33係以 一棒形實體構件作成。 可透氣護裙3 4係作捲摺，而可部分的接觸吸取管3 2、 部分接觸捲摺構件33及部分接觸底部鉗夾滾子35a，而因 底部鉗夾滾子35a之轉動，其在滑動面32b與32a上作滾 動之同時，亦爲可轉動。此實施例中，可透氣護裙3 4係以 編織纖維作成，以確保適當之透氣性。 1243865 如第1、2a、…等圖所示，在捲摺構件33之下方及附近 ，設有一單一型氣動裝置之吸取嘴4 9，當自牽伸裝置11 送出之纖維束F發生斷線時，可用以將其吸入。吸取嘴4 9 之座端係連接於以全部錠子單元持分之一氣動導管5 0。 其次，說明上述所構成之裝置的動作。 當紡絲機動作時，各纖維束F係行經底部滾子1 2〜1 4與 頂部滾子1 9〜2 1之間作牽伸，之後，引導至纖維束收集 (捲繞）裝置30。 送出部3 1之頂部鉗夾滾子3 1 a轉速，係快於各前方底部 鲁 滚子1 2與則方頂部滾子1 9之表面速度有某種程度，且在 適當張力下、行經送出部3 1之鉗夾點後，纖維束F係朝下 游側移動，並接受加撚作用。 又，導管4 4之吸取作用係經連接管4 8運用於吸取管3 2 ，而滑動面3 2 b所開設吸取孔3 2 a之吸取作用，係經透氣 護裙34運用於纖維束F。再者，當纖維束F被吸取時仍爲 移動，而在對應於吸取孔3 2 a之位置上作收集。因此，較 諸未設纖維束收集裝置3 0之構造而言，乃可抑制絨毛之產 春 生及棉材之耗費，並因之而改善線的品質。 由於捲摺構件3 3係設在吸取管3 2之下游側，並與吸取 管3 2相分離，故如第4a圖所示之絲絨角度θ 1，乃較諸取 除捲摺構件3 3後，如第4b圖所示之絲絨角度Θ2爲大。在 絲絨角度較大之狀態中，當纖維束F行經鉗夾點後、直到 自可透氣護裙3 4之表面離開前，其所覆蓋之距離係相當的 長。因此，由於來看捲取部所運用於纖維束F上之加撚作 1243865 用’纖維束乃旋動，則由纖維束F之周圍突伸出（sticking-out)之纖維f可和透氣護裙3 4相接觸，纖維f即可易於撚 捻或纖維束F，乃因而抑制絨毛之產生。又，如第5 a圖所 示’於存在有捲摺構件3 3之結構中，纖維束F在護裙上作 滾動時，係成往復式，結果，自纖維束F周圍突伸出之纖 維f即可易於撚捻成纖維束F。 反之，倘絲絨角度爲較小之狀態時，在纖維束F行經鉗 夾點後、直到自透氣護裙3 4之表面分開前，其所覆蓋之距 離將甚短。因之，由於來自捲取作用而運用於纖維束FI 鲁 之加撚作用，甚難令纖維束F旋轉，以令自纖維束周圍突 伸出之纖維f與透氣護裙34相接觸，故纖維即無法撚捻成 纖維束F，因而即產生有絨毛。又，如第5 b圖之構造中， 係未設捲摺構件3 3，且其中透氣護裙3 4係圍繞底部鉗夾 滾子3 5 a與吸取管3 2作捲摺，故纖維束F無法在護裙上滴 動，但可作往復式滑動。結果，由纖維束F周圍突伸出之 纖維f即難以輕易的即撚捻成纖維束F。 爰利用裝設具有捲摺構件3 3之纖維束收集裝置的紡絲 鲁 機及裝設不具捲摺構件3 3之纖維束收集裝置的紡絲機，各 均紡絲生產40支紗之線，而遂行有毛程度（hair i ness)暨U % 等之計測。由測得之結果獲知，具有捲摺構件3 3者，較可 滿足U%項，但並無極大優越性。反之，就有毛程度而言， 設有捲摺構件3 3者’即具有明顯之效果。第6圖爲關於有 毛程度之測量結果圖。注意者，乃以上所稱之”有毛程度 (hairiness)”之含義，係指lcm之線所存在絨毛（stuff)之總 -15- 1243865 長度（cm)而言。實務上，有毛程度通常不以單位表示。在 具有捲摺構件3 3之狀況中，平均有毛程度之値爲3 · 64，反 之’在不具捲摺構件3 3之狀況中，平均有毛程度之値則爲 3.9 6。一般而言，兩相比較下，有毛程度之値的差異如果 有0 · 1時，數値較小者即爲較優。因此，依上述測量結果 之狀況，其間差値達〇 · 3，即可淸楚獲知何者對抑制產生絨 毛之功效較爲優異。此外，倘連纖維束收集裝置3 〇均未裝 設之紡絲機，其紡絲所得之有毛程度値高達4 · 7 7，良窳立 見。 · 依傳統觀念之認知，倘增加絲絨角度，將導致斷線之虞 。但是’如設以纖維束收集裝置3 0時，因纖維束F係自鉗 夾點抽出、同時，即藉吸取孔3 2 a之吸引作用加以收集， 故由捲取作用所致之撚捻係易於達至鉗夾點附近，乃可因 之而增加線的強度，故即使增加了絲絨角度，仍可抑制產 生斷線之或然率。因此，可抑制因斷線所致產能之減少。 依此一實施例，至少具有下列之優點： a)纖維束收集裝置3 0係裝附有設在送出部之鉗夾點下游 φ 側（對纖維束F之移動方向而言）的吸取管3 2，且當可透氣 護裙3 4與吸取管3 2之滑動面3 2b相接觸時係可轉動。再 者，在對纖維束F移動方向而言、該吸取管3 2之下游側設 有捲摺構件3 3，係和吸取管3 2相分離，該可透氣護裙3 4 則係圍繞該捲摺構件3 3作捲摺，如是，即增加了絲絨角 度。因之，可增大抑制產生絨毛之功效，而可更進一步抑 制產生絨毛，因而達成了線品質之改善。又者，即使增加 了絲絨角度，但纖維束F自鉗夾點抽出後，即同時被吸取 -16- 1243865 孔3 2 a之吸取作用所收集，則因捲取作用所致之撚捻乃達 於鉗夾點之附近，因之，即可抑制斷線狀況之增加。 b) 捲摺構件3 3之設置方式爲，送出部3 1之鉗夾點及纖 維束離開鉗夾點下游側上之可透氣護裙3 4的位置，該鉗夾 點與該位置兩者間之距離係不小於5 m m。因此，纖維束F 移動時，亦同時在可透氣護裙3 4上作滾動，則纖維束F之 突伸出纖維f乃極易予以撚捻爲纖維束F，因此，可改善絨 毛產生抑制效果。 c) 以可透氣護裙34捲摺作圍繞之吸取管32及捲摺構件 φ 3 3，其等之支持方式爲，各該吸取管或捲摺構件之至少一 端，係與以裝卸式支持於設在機座框架上之支持部1 5a、 3 8 a成配套之啣接。因此，即可易於配置吸取管3 2與該捲 摺構件33，使上述之距離不小於5mm。 d) 捲摺構件33係由棒形構件所作成。因此，較諸捲摺構 件33作成爲管形之型式而言，乃可促進其之生產。又，即 使在作按裝、拆卸、及保養作業時，捲摺構件3 3觸及了其 他構件，其亦不易受損。 φ e) 以頂部鉗夾滾子31a加壓於可透氣護裙34之力量係由 底部鉗夾滾子3 5 a所產生，且頂部鉗夾滾子3 1 a之加壓力 量並不施加於吸取管32,故比較傳統裝置（JP 1 1 -2 8 6 8 3 7 A) 之狀況而言，吸取管3 2所須之剛性即可較小，倘由樹脂作 成時，即可確保具有足夠之強度。 g)作爲負壓源之導管44設有獨立之氣動裝置，當發生斷 線時，可吸取由牽伸部所送出之絲絨（fleece)，故吸取管32 -17- 1243865 之吸取壓力即可易於調整爲適當之壓力。 本發明自非僅局限如上述之實施例構造，其亦可採用例 如下述之構成。 關於：送出部3 1之鉗夾點及纖維束F離開位於送出部 3 1之鉗夾點下游側上之可透氣護裙3 4的位置，兩者間之 距離L，如此一距離l不小於5mm時，即可有效的抑制絨 毛之產生。而距離L之値並無特別之上限，僅管如此，但 如該距離L太長，對於抑制產生絨毛之功效並非等比的大 幅增加而僅爲增加了機座之尺寸而已，是故，該距離之範 φ 圍以在8〜1 0 mm之間最爲恰適。 纖維束收集裝置3 〇之送出部結構，並非僅限制爲裝設有 一對鉗夾滾子者，例如，其亦可採用一種可驅動可透氣護 裙3 4之構造，包括：排除吸取管3 2與底部鉗夾滾子3 5 a ，設以剖面成蛋形之吸取管，在吸取管之預定位置設以吸 取孔，將可透氣護裙3 4圍繞吸取管與捲摺構件3 3之外周 作滑動式之捲摺等之構成，則，將頂部鉗夾滾子3 1 a作正 性之驅動，藉驅動頂部鉗夾滾子3 1 a而驅動可透氣護裙 鲁 34，同時，令該頂部鉗夾滾子保持和可透氣護裙34相接觸 。則在此狀況中，即可將用於可透氣護裙3 4、具調整功能 之張力加諸於捲摺構件3 3上。 吸取管3 2、捲摺構件3 3、及轉動軸3 5之結構非限制僅 爲4個錠子單元構成爲一組單元。其亦可採用在相鄰近滚 子架1 5間之錠子單元（例如8個錠子單元）構成爲一組單元 之結構，或採用兩個錠子單元構成爲一組單元之結構。又 -18- 1243865 ，所有之單元並不需要經常具有相同數量之錠子單元，其 、 亦可令相鄰近滾子架1 5間之錠子單元數量彼此間爲不同 (例如6個與2個），因而形成爲兩種不同之單元組數。 除了以實體構件形成捲摺構件3 3之方式外，亦可將其構 成爲管形之型式，此狀況中，可減輕其重量。 吸取管3 2之端部亦可加以封閉之。此狀況中，即不須使 用端部插塞4 0對吸取管3 2之端部作全密閉式之密封，只 須設以啣接軸承3 9之啣接孔，及設以啣接吸取管3 2之端 部與捲摺構件3 3之啣接部（啣接孔）即可，對生產將有助益。鲁 亦可採用一種構造，其中令：吸取管3 2之端部及位在和 端部插塞4 0成配套啣接之端部，其對向側上之捲摺構件 33等兩者，藉由一可予連接到連接管49之連接構件而形 啣接。 除了在縱長方向設以多數導管44之方式外，亦可設成以 一單一導管延伸貫穿紡絲機整個機座長度之方式爲之。 導管4 4之位置並不限制僅爲位在牽伸裝置1 1之後側與 上方之一種方式，其亦可爲配置在牽伸裝置1 1之後側、或 鲁 後側與下方等之方式。 除了以配設於紡絲框（機）右側與左側之諸吸取管3 2共同 持分該導管44的配置方式外，亦可採用另種配置方式，其 中把複數導管依兩排作配設，左、右各1排，而可依紡絲 機機座之縱長方向作延伸者。 抽吸裝置之構造非僅限制爲以馬達47驅動風扇47a之該 種型式，其亦可爲例如，採用減壓式泵浦（真空泵浦）之方 -19- 1243865 式。真空泵浦可爲旋轉式泵浦或爲往復式泵浦。

invention: The technical field to which the invention belongs: The present invention relates to a fiber bundle collection (c ο 11 ecting, also known as winding) device of a spinning machine, in particular to a fiber of a spinning machine The bundle collecting device is arranged on the upstream side of the drafting device (drawing part) of the spinning frame to collect the fiber bundle drafted by the drafting device. Prior art: In the conventional technology, Japanese Patent No. JP 0 72 3 8 42, i ..... discloses the ^ -type fiber bundle collection device, as shown in FIG. One of the stretching devices is provided on the downstream side of the final roller 61 with a pair of conveying rollers 63 equipped with a punching skirt 62; and a suction device 64 is provided for conveying the punching skirt 62 Suction is applied to the surface. In such a fiber bundle collecting device, the suction air flow is applied to the conveying surface of the punching skirt 62 through a suction groove formed by a skirt cage 65 to guide the punching skirt 62. Similarly, DE 1 970 8 4 1 0 A1 is also a fiber bundle collecting device. As shown in FIG. 8, on the downstream side of a pair of final rollers 7 1 constituting a drafting device, A pair of conveying rollers 7 3 equipped with a perforated skirt 72 2 forming a conveying surface of the fiber bundle; and a suction device 74 is provided to apply a suction air flow to the conveying surface of the perforated skirt 72. In this device, the suction air flow is applied to the conveying surface of the punching skirt 72 through a groove formed in a skirt guide 75 to guide the punching skirt 72. The tension is applied to the punching skirt 72 by a guide member 76. In this state, the guide member is a rotator. -6 · 1243865 Moreover, in the fiber bundle collection device disclosed in JP 1 2 2 6 6 8 3 7 A, a downstream side of the final roller and a bottom side of a drafting device are provided with A hollow profile (bow 丨 guide tube) that absorbs the static sliding surface of the crack, and a belt for conveying is provided therein, which is rolled around the hollow profile. In this device, a jaw roller is provided on the top side, which is held in contact with the punched belt to reveal a jaw point. The above-mentioned clamp roller is driven by the above-mentioned final roller through a transmission belt. In addition to the structure that drives the jaw roller via a transmission belt, the case also discloses a structure that achieves a driving function through a transmission roller contacting the final roller. Compared to threads produced by spinning using a spinning machine without a fiber bundle collecting device, threads produced by spinning using a spinning machine equipped with a fiber bundle collecting device are more suitable for producing fluff (fluff ) And thread specks can be reduced to U%. However, there are still areas for further improvement. Those in the industry know that increasing the "fleece (or fleece) angle" will effectively suppress the generation of fluff. However, similarly, there will be a risk of disconnection, so it is a great disadvantage in terms of operation. The meaning of the "velvet angle" mentioned above refers to the folding fan shape connected to the center of the curvature of the curved surface (the fiber bundle ((velvet)) that has passed through the clamping point along this curved surface is guided to the extraction position) Segments and clamp points; and angles made by a folding fan-shaped segmental plate connected to the center of the curvature and the extraction end for the fiber bundle F. The above-mentioned fiber bundle collection device has not seen any increase. The velvet angle can suppress the production of fluff to improve the technical ideas and practical methods of quality. For example, 1243865 in JP-0 7-23 842 5 A, as described above, in Figure 7, the fiber bundle F is on the delivery roller On the downstream side of the clamping point of 63, the tangent direction was taken out, and there was no increase in the velvet angle. In the case of DE 197 0 8 4 1 0 A1, the fiber bundle F was also sent out. The downstream side of the gear pair 7 3 is drawn in a tangential direction without consideration of increasing the velvet angle. Summary of the Invention: The inventor of this case has prepared a fiber bundle collection device with a positive increase of the velvet angle. The beam collecting device is installed in a spinning machine, A high-speed image camera was used to take in the thread φ (thread) obtained from the spinning of such a spinning machine; and then, a spinning machine equipped with a conventional fiber bundle collecting device and the spinning obtained thread were compared in two situations. It was found that after increasing the velvet angle, the thread (fiber bundle) was reciprocated and rolled along the skirt on the upstream side of the pinch point of the delivery roller pair; while the traditional structure with a smaller velvet angle, the thread was slippery The reciprocating movement of the shape of the shape. In addition, I also measured the hairiness (hairiness) and U% of the yarn obtained from the spinning. According to the results of the measurement, it was found that U% in both cases was very large. However, in terms of hairiness, this structure with a positively increased velvet angle has extremely excellent performance. The inventor of the present case has completed the present invention based on this recognition. Therefore, the present invention The purpose is to provide a fiber bundle collecting device for a spinning machine, in which the present invention can greatly suppress the generation of hair loss compared with the conventional device using a single structure, and can improve the quality of the thread. In order to achieve the above purpose, according to the present invention Invention The fiber bundle collecting device of a spinning machine relates to a fiber bundle collecting device for collecting fiber bundles drawn by a drafting section of a spinning machine, and includes: a sending section, which is arranged at the drafting section -8-1243865 On the downstream side of the final delivery roller, there is a suction portion for the moving surface of the clamping roller. The sliding surface is provided with a suction hole. The upstream side of the clamping point of the output portion is extended to form an extension portion. A breathable skirt is provided on the downstream side of the suction part in the direction of movement of the fiber bundle when it contacts the sliding surface. The breathable skirt is rolled around the rolled member due to the velvet angle. In the present invention, the fiber bundle drafted by the drafting portion is collected by a pair of fiber bundles on the downstream side of the roller which is finally sent out, and is moved in the collected state. As far as the silk machine is concerned, the generation of fluff can be suppressed, which is also costly, and thus the quality of the thread can be improved. In addition, since the downstream side of the suction section is folded and provided separately, it is possible to increase the silk and increase the effect of suppressing the generation of fluff, so that it can be produced further, and the quality of the thread can be improved as a result. When the fiber bundle runs, it moves towards the downstream side and undergoes twisting (twisth because the fiber bundle is drawn from the clamping point and collected by the suction hole, it is due to the take-up effect near the clamping point (taking- !! Increase the strength of the wire, so it is easy to heat, even if it is increased, the occurrence of disconnection can be suppressed. Implementation: The following is a description of one embodiment of the present invention with reference to Figures 1 to 6. The drawing shows a drafting device and a side of a fiber. Figure 2a shows the point where the clamp is held according to the direction of fiber extraction; a self-propelled with a slip fiber bundle; and a rotatable forming member; and Increasing the collection at the drafting section to collect the φ fiber bundle can suppress the cotton material system is set at the 糸 Rong angle 'and suppress the fluff diameter clamp pinch after ig action).

In addition, when the lever 1 8 a is turned from the position shown in FIG. 1 to the upper position to obtain the release position, the locked state is released. 1243865 As shown in FIG. 1, a fiber bundle collecting device 30 is disposed downstream of the final conveying roller of the drafting device 11. The fiber bundle collecting device 30 is provided with a conveying section 31, a suction pipe 3 as a suction section 2, a roll folding member 33, and a breathable skirt 34. The conveying part 31 is composed of: a bottom jaw roller 3 5 a 'which is formed on a rotating shaft 35 which is parallel to the front bottom roller 12; and a top jaw roller 31 a, which It is composed of the adjustment of the breathable skirt 34 and the pressing of the bottom clamp roller 3 5 a. As shown in Fig. 2a, in the fiber bundle collecting device 30 of this embodiment, similar to the Lu top rollers 19 to 21, the top jaw roller 3 1a is supported by a weighting arm 18 through a support. The adjustment of the member 36 (shown in Figs. 1 and 3) is supported in each spindle. Note that, in this embodiment, the supporting member 36 is integrally formed with the supporting member of the front top roller 19. On the other hand, on the bottom side of the fiber bundle collecting device 30, half of the spindles are arranged between two mutually adjacent roller frames 15 of the drafting device 11, that is, this embodiment has 4 spindles. Sub-systems constitute a group of units. At the middle position of the roller frame 15 arranged at predetermined intervals according to the lengthwise direction of the machine base, a support arm 38 (shown only in FIG. 2a for forming the machine frame) is arranged. Therefore, the bottom end is supported by a support beam 37 extending in the longitudinal direction of the machine base, and a rotating shaft 35 is arranged between the roller frame 15 and the support arm 38. As shown in Fig. 2b, the length of the rotating shaft 35 is made corresponding to a plurality of spindles (four spindles in this embodiment), and any one end can be fixed with a bearing 39. The bearing 39 is fitted in the end plug 40, and, as shown in FIG. 2a, FIG. 1243865, the end plug 40 is a support portion 15a provided on the roller frame 15 and the support arm 38. And 3 8a are supported in the joint portion 40a. Therefore, the rotation shaft 35 is rotatably supported between the roller frame 5 and the support arm 3 8. The support portions 1 5 a and 3 8 a are formed in such a manner as to support two end plugs 40 fixed to the ends of the adjacent rotating shafts 35. The support portion 15a is formed by a block (bloc) fixed to the roller frame 5 and has an engaging notch, which extends upward in an oblique direction on the front side of the base. The support portion 3 8 a also has an engaging recess, which extends upward in the oblique direction on the front side of the machine base. It has-the end plug 40 of the connecting portion 40a can be connected to these notches, then, with a simple action, the supporting portions 1a and 3a can be pressed and stuck Entered in the connecting section 40a. A gear 4! Is integrally formed at the center of the rotation axis 35 in the longitudinal direction. As shown in Fig. 3, the front bottom roller 12 is provided with a gear portion 12a at a position facing the gear 41. In addition, an intermediate gear 43 meshing with the gear portion 12a and one of the gears 41 is rotatably supported by a support arm 42. The bottom of the support arm 42 is fixed to the support beam 37 similarly to the support arm 38. . That is, the torque of the front bottom roller i 2 is transmitted to the rotating shaft 35 through the gear portion 12a, the intermediate gear 43, and the gear 41. As shown in Fig. 1, in the frame of the spinning frame (machine), a plurality of conduits 44 serving as a suction source (negative pressure source) for the fiber bundle collection device are arranged in the longitudinal direction (for The plane shown in Figure 1 is vertical). The plurality of ducts 44 extend in the longitudinal direction of the base of the spinning machine. A suction device 45 for maintaining the negative pressure of each of the catheters 44 is connected to each of the catheters 44 via a pipe 46. The suction device 45 is composed of a fan motor, and the fan is driven by a motor 4 7 driving 1243865. As shown in Fig. 1, the ducts 44 to 44 are arranged above the drafting device 11 at the rear side and at the center of the spinning machine base, and the suction devices 45 are also arranged below the duct 44. The suction pipe 32 is connected to the catheter 44 through a connecting pipe 48, so it extends parallel to the catheter 44. The support state of the suction tube and the folding member 33 is also, and the ends thereof are matched with one of the pair of end plugs 40 supporting the rotation shaft 35. The suction tube 32 has a sliding surface 3 2b. The sliding surface is provided with a plurality of crack-shaped suction holes 32a. The positions of the suction holes are for the fiber bundle (velvet) F to clamp the roller 3 5 a at the bottom. In terms of the movement direction, it is arranged along the extension φ toward the upstream side. The folding member 3 3 has a sliding surface 3 3 a for slidingly guiding the breathable skirt 34. As shown in Figs. 3 and 4a, as for the moving direction of the fiber bundle F, the suction pipe 3 2 is arranged upstream of the clamping point of the bottom clamping roller 3 5 a, and the folding member 3 3 is It is arranged on the downstream side. The suction pipe 32 is configured to guide the breathable skirt 34 to the vicinity of the clamping point of the front bottom roller 12 and the front top roller 19. The configuration of the folding member 3 3 is such that the distance L between the position where the clamp point and the fiber bundle are separated from the breathable skirt 34 on the downstream side of the clamp point is not less than 5 mm, and The best is 8 ~ 10mm. The rolled member 33 is made of a rod-shaped solid member. The breathable protective skirt 3 4 is used for folding, and can partially contact the suction pipe 3 2. Partly contacts the folding member 33 and partly contacts the bottom jaw roller 35a, and due to the rotation of the bottom jaw roller 35a, it is The sliding surfaces 32b and 32a are also rotatable while rolling. In this embodiment, the breathable skirt 34 is made of woven fibers to ensure proper breathability. 1243865 As shown in Figs. 1, 2a, ..., a single-type pneumatic device suction nozzle 4 9 is provided below and near the folding member 33. When the fiber bundle F sent from the drafting device 11 is disconnected Can be used to inhale it. The seat end of the suction nozzle 49 is connected to a pneumatic duct 50 held by one spindle unit. Next, the operation of the device configured as described above will be described. When the spinning machine is operating, each fiber bundle F is drawn between the bottom rollers 12 to 14 and the top rollers 19 to 21, and then guided to a fiber bundle collection (winding) device 30. The rotation speed of the top jaw roller 3 1 a of the sending part 3 1 is faster than the surface speed of the front bottom rollers 12 and the square top rollers 19 to some extent. After the clamping point of the part 31, the fiber bundle F moves to the downstream side and receives twisting action. In addition, the suction action of the catheter 44 is applied to the suction pipe 3 2 through the connecting pipe 48, and the suction action of the suction hole 3 2 a opened by the sliding surface 3 2 b is applied to the fiber bundle F through the breathable skirt 34. Furthermore, when the fiber bundle F is sucked, it still moves and is collected at a position corresponding to the suction hole 3 2 a. Therefore, compared with the structure without the fiber bundle collecting device 30, it is possible to suppress the production of fluff and the consumption of cotton material, and to improve the quality of the thread. Since the roll-up member 3 3 is located on the downstream side of the suction pipe 32 and is separated from the suction pipe 32, the velvet angle θ 1 shown in FIG. 4a is smaller than that after the roll-up member 3 3 is removed. As shown in Figure 4b, the velvet angle Θ2 is large. In a state where the velvet angle is large, the distance covered by the fiber bundle F after passing through the clamp point until it leaves the surface of the breathable skirt 34 is relatively long. Therefore, since the twisting operation applied to the fiber bundle F by the winding section is 1243865, the fiber bundle is rotated, and the sticking-out fiber f surrounding the fiber bundle F can be used as a breathable protective layer. When the skirts 3 and 4 are in contact with each other, the fiber f can be easily twisted or the fiber bundle F, thereby suppressing the generation of fluff. Also, as shown in FIG. 5a, in the structure in which the folding members 33 are present, when the fiber bundle F rolls on the skirt, the fiber bundle F is reciprocated. As a result, the fibers protruding from the periphery of the fiber bundle F f can be easily twisted into a fiber bundle F. Conversely, if the velvet angle is relatively small, the distance covered by the fiber bundle F after passing through the pinch point and before being separated from the surface of the breathable skirt 34 will be short. Therefore, due to the twisting effect applied to the fiber bundle FI from the winding action, it is difficult to rotate the fiber bundle F so that the fiber f protruding from the periphery of the fiber bundle contacts the breathable skirt 34, so the fiber That is, the fiber bundle F cannot be twisted, and fluff is generated. Also, as in the structure of FIG. 5b, the folding member 3 3 is not provided, and the breathable protective skirt 3 4 is folded around the bottom clamp roller 3 5 a and the suction tube 32, so the fiber bundle F Can not drip on the skirt, but can be reciprocated sliding. As a result, the fibers f protruding from around the fiber bundle F are difficult to twist easily into the fiber bundle F.爰 Spinning machine equipped with a fiber bundle collection device with a folding member 33 and a spinning machine equipped with a fiber bundle collection device without a folding member 33, each spinning a yarn of 40 yarns, Hair i ness and U% were then measured. It is known from the measurement results that those with 33 folded members can better meet the U% term, but have no great advantage. Conversely, in terms of the degree of hair, the effect of providing the folding members 33 is obvious. Figure 6 is a graph showing the measurement results of the degree of hairiness. Note that the meaning of "hairiness" mentioned above refers to the total length of -15-1243865 (cm) of the stuff in the lcm line. In practice, the degree of hairiness is usually not expressed in units. In the case of having the folded member 33, the average hairiness degree was 3.64, and on the contrary, in the case of the case without the folded member 33, the average hairiness degree was 3.96. Generally speaking, if there is a difference of 程度 in the degree of hairiness between two comparisons, the smaller the number, the better. Therefore, according to the condition of the above measurement results, the difference is as much as 0.3, and it can be known which is more effective in suppressing the generation of fluff. In addition, if the fiber bundle collection device 30 is not equipped with a spinning machine, the degree of hairiness obtained from spinning is as high as 4.77, which is a good idea. · According to the traditional perception, if the velvet angle is increased, it may cause disconnection. However, if the fiber bundle collection device 30 is set, the fiber bundle F is drawn from the clamping point, and at the same time, it is collected by the suction effect of the suction hole 3 2 a. Therefore, the twisting system caused by the winding effect It is easy to reach the vicinity of the clamping point, which can increase the strength of the thread, so even if the velvet angle is increased, the probability of disconnection can still be suppressed. Therefore, it is possible to suppress a reduction in production capacity due to a disconnection. According to this embodiment, it has at least the following advantages: a) The fiber bundle collecting device 30 is equipped with a suction tube 3 (for the direction of movement of the fiber bundle F) provided on the φ side downstream of the clamping point of the sending portion. 2, and can be rotated when the breathable protective skirt 34 is in contact with the sliding surface 3 2b of the suction tube 32. Furthermore, in the direction of movement of the fiber bundle F, a folding member 3 3 is provided on the downstream side of the suction pipe 32, which is separated from the suction pipe 32, and the breathable skirt 3 4 is wound around the roll. The folding member 33 is rolled, and if so, the velvet angle is increased. Therefore, the effect of suppressing the production of fluff can be increased, and the production of the fluff can be further suppressed, thereby improving the thread quality. In addition, even if the velvet angle is increased, the fiber bundle F is collected by the sucking action of -16-1243865 hole 3 2 a at the same time after being pulled out from the clamping point. It is near the clamping point, so that the increase of disconnection can be suppressed. b) The folding member 3 3 is arranged in a position where the jaw point and the fiber bundle of the sending part 31 leave the breathable skirt 34 on the downstream side of the jaw point, and the jaw point is between the jaw point and the position The distance is not less than 5 mm. Therefore, when the fiber bundle F moves and also rolls on the breathable skirt 34, the protruding fiber f of the fiber bundle F can be easily twisted into the fiber bundle F. Therefore, the effect of suppressing the generation of fluff can be improved. . c) A suction tube 32 and a folding member φ 3 3 surrounded by a breathable protective skirt 34 are rolled, and the other support methods are that at least one end of each suction tube or folding member is supported by a detachable support on The supporting parts 15a and 38a provided on the frame of the machine base are matched and matched. Therefore, it is possible to easily arrange the suction pipe 32 and the folding member 33 so that the above-mentioned distance is not less than 5 mm. d) The rolled member 33 is made of a rod-shaped member. Therefore, the production of the roll-folding members 33 can be promoted compared to the tube-shaped ones. In addition, even when the assembling, disassembling, and maintenance operations are performed, the folding member 33 is in contact with other members, and it is not easily damaged. φ e) The force of pressing the top jaw roller 31a to the breathable skirt 34 is generated by the bottom jaw roller 3 5 a, and the pressing force of the top jaw roller 3 1 a is not applied Suction tube 32, so compared with the situation of traditional devices (JP 1 1-2 8 6 8 3 7 A), the rigidity required by the suction tube 32 can be smaller, if it is made of resin, it can ensure that it has sufficient The intensity. g) The conduit 44 as a negative pressure source is provided with an independent pneumatic device. When a disconnection occurs, the fleece sent by the drafting portion can be sucked, so the suction pressure of the suction tube 32 -17-1243865 can be easily Adjust to appropriate pressure. The present invention is not limited to the structure of the embodiment described above, and it can also adopt the structure of the following. About: The position of the gripping point of the sending section 31 and the fiber bundle F leave the breathable skirt 34 located on the downstream side of the gripping point of the sending section 31. The distance L between the two is such that the distance l is not less than When it is 5mm, it can effectively suppress the generation of fluff. There is no special upper limit for the distance L, just so, but if the distance L is too long, the effect of suppressing the generation of fluff is not a substantial increase but only increases the size of the base. Therefore, the The range of distance φ is most suitable between 8 and 10 mm. The structure of the sending part of the fiber bundle collecting device 3 〇 is not limited to those equipped with a pair of pinch rollers. For example, it can also adopt a structure that can drive a breathable skirt 3 4, including: removing the suction tube 3 2 Clamp the roller 3 5 a with the bottom, set a suction tube with an egg-shaped cross section, set a suction hole at a predetermined position of the suction tube, and surround the breathable skirt 3 4 around the suction tube and the folding member 33 For sliding type folding, etc., the top jaw roller 3 1 a is driven positively, and the breathable skirt 34 is driven by driving the top jaw roller 3 1 a. At the same time, the top The jaw rollers remain in contact with the breathable skirt 34. In this situation, the tension for the breathable skirt 34 and the adjustment function can be applied to the folding member 33. The structure of the suction tube 3 2, the folding member 3 3, and the rotating shaft 35 is not limited to only 4 spindle units configured as a group of units. It can also adopt a structure in which a set of units (for example, 8 spindle units) between 15 adjacent roller racks is used, or a structure in which two spindle units are used as a group of units. -18-1243865, all the units do not always need to have the same number of spindle units, and it can also make the number of spindle units of 15 adjacent roller racks different from each other (for example, 6 and 2) ), Thus forming two different numbers of unit groups. In addition to the manner in which the rolled member 33 is formed of a solid member, it can also be formed into a tubular shape, in which case its weight can be reduced. The end of the suction tube 32 can also be closed. In this case, it is not necessary to use the end plug 40 to completely seal the end of the suction tube 32, only the connection hole for the bearing 39 and the suction tube need to be provided. The connection between the end of 3 2 and the folding member 3 3 (connection hole) is sufficient, which will help production. Lu can also adopt a structure in which: the end of the suction tube 32 and the end located in a matching connection with the end plug 40, the folding member 33 on the opposite side, etc. Formed by a connecting member which can be connected to the connecting pipe 49. In addition to the manner in which a plurality of ducts 44 are provided in the longitudinal direction, it can also be set such that a single duct extends through the entire length of the spinning machine. The position of the catheter 44 is not limited to only one way of being located behind and above the drafting device 11, and it can also be arranged in the way of the rear side of the drafting device 11, or behind and below. In addition to the configuration of the duct 44 held by the suction tubes 32 arranged on the right and left sides of the spinning frame (machine), another configuration can also be adopted, in which a plurality of ducts are arranged in two rows, left One row to the right and one to the right, and can be extended according to the longitudinal direction of the spinning machine base. The structure of the suction device is not limited to the type in which the fan 47a is driven by the motor 47, and it may also be, for example, a method using a pressure reducing pump (vacuum pump) -19-1243865. The vacuum pump can be a rotary pump or a reciprocating pump. In addition to using woven fibers to make breathable skirts 3, 4 can also be made of knitted fibers. In addition to eliminating the need to open a lot of small holes in the belt to form a breathable skirt, it can still maintain proper ventilation In addition to performance, it can also reduce the manufacturing cost of breathable skirts. In addition, because the knitted fiber has elasticity, the breathable protective skirt can be rotated under appropriate tension without the need for any other special tension device. In addition to using cotton fibers or knitted fibers to make breathable skirts, it is also possible to punch holes in a plurality of resin belts made of rubber or elastic resin to form breathable skirts 34 with φ. It is also possible to adopt a structure in which a rotating shaft 3 5 with a bottom jaw roller 3 5 a formed thereon may be held by a full-scale spindle unit; and a motor may be used as a drafting device 1 1 The condition of the bottom rollers 1 2 to 1 4 is a shaft member that is provided by a row of gears at the gear end of the machine base for driving. The suction tube 32 and the pneumatic device can use a common negative pressure source. Regarding the pneumatic device, in addition to the type of a single pneumatic nozzle, a flute-type structure can also be adopted. _ As detailed above, the fiber bundle collecting device according to the present invention can be made into a simple structure, which can further suppress the generation of fluff compared with conventional techniques, and can achieve the effect of improving the quality of the thread.
