1278543 玖、發明說明： 發明所屬之技術領域 本發明係關於一種纖維束（fiber bundle)集束裝置 (collecting device)及紡紗機（spinning machine)，特別是關 於一種纖維束集束裝置，其係配置在例如一精紡機 (spinning frame)之牽伸裝置（牽伸部）的下游側，並用以收 集以牽伸裝置所牽伸之纖維束；及一種紡紗機，其係裝設 有纖維束集束裝置者。 先前技術 第7圖爲揭示一種裝設此種型式之纖維束集束裝置的紡 紗機例（見例如日本；IP 2000-73 224A號）。一精紡機之機座 兩側，裝設有複數之精紡站7 1，而纖維束集束裝置則裝設 具有多數吸取裂縫（吸取孔）之吸取外型（suction profile)72 與7 3，該等吸取裂縫係對應該等精紡站71設置，並對牽 伸裝置所牽伸之纖維束上施加吸取動作。吸取外型72與73 係分別經吸取管74與75連接於吸取裝置76與77。吸取 裝置76與77係裝設有藉馬達78驅動之風扇79。在此種 纖維束集束裝置中，吸取裝置76與77係分別提供用於固 定數量之精紡站7 1，故作用在單獨精紡站7 1之吸取裂縫 上的吸取壓力差乃減少，因之，以精紡所得之線（thread、 或紗）的品質差異即可降低，達可容許之水準。 又者，依該JP-2〇〇〇_73 224A號案，爲了監視真空狀態及 線的品質，乃在吸取管7 4與7 5分別設以壓力計測裝置， 且萬一發生故障時，相關機器部分之動作即停止。 -5- 1278543 ， 較諸一種結構，其中和全部精紡站共通之一吸取通道， > 係以一單一抽真空風扇保持爲真空狀態，且其中纖維束集 束裝置係連接於此一通道，JP-2000-73224A號案所揭示之 裝置中，以各精紡站7 1精紡所得之線的品質差異較易於降 低至可容許之水準。但是，用於把吸取作用分給成爲一群 一 之各精紡站7 1的吸取外型7 2、7 3的吸取裝置7 6、7 7之數 ^ 量係限制爲1個，故當一個吸取裝置故障時，則對分配於 該吸取裝置之吸取外型上，即未有產生吸取作用。結果， 倘持續作精紡，則以未有吸取作用下之精紡站7 1所得之線 鲁 品質’與具有吸取作用下之精紡站7 i所得之線品質，兩者 之品質差異勢將超出可容許之範圍。 依上述之公開案，係在吸取管74、75分別安裝壓力計測 裝置且在發生故障時，立即停止相關機器部分之運作，用 以解決上述之問題。但是，該公開案中，對停止相關機器 部分運作之機構卻未見諸有任何說明。此外，當精紡機非 爲一種所稱之單一鍵子驅動型（single-spindle-drive type) 時，用以停止相關機器部分運作之機構勢必更爲繁複，意 鲁 即將增加所耗費之成本。 此外，於JP-2〇〇〇-73224A號案之裝置中，各一吸取管74 、7 5係分別連接各對應8個精紡站7 1之吸取外型7 2、7 3 。當用以承受來自一吸取外型7 2、7 3之精紡站7 1數量增 加時，則較靠近吸取管7 4、7 5之精紡站7 1的吸取作用、 及離該吸取管74、7 5較遠之精紡站的吸取作用，兩者間之 差異亦將增加。結果，以複數不同精紡站7 1精紡所得之多 -6- » 1278543 數線中，即甚易產生品質之變化。在JP-200 0-73 224A號案 所揭示之裝置中，吸取管74與75係直接連接於吸取裝置 76與77，爲了減少用以接受來自一吸取外型72、73之吸 取作用的精紡站數量，如擬增加連接於吸取裝置7 6、7 7之 吸取管74、7 5的數量，將更爲困難。進者，倘不增加吸取 一 管之數量，而係增加吸取裝置之數量惟不增加連接於一吸 · 取裝置之吸取管數量時，此亦將增加成本。 發明內容 本發明係鑑諸習用技術之問題而提供。本發明之一目的 鲁 ’係提供一種用於一紡紗機之纖維束集束裝置其中，即使 在任何一個吸取裝置發生了異常，亦可使：在該異常吸取 裝置之吸取作用下、以精紡單元（精紡站）精紡所得之線的 品質；及在其他吸取裝置之吸取作用下、精紡所得之線的 品質；兩者品質間之差異保持在可容許之範圍內者。 依本發明，係提供一種用於收集一由一紡紗機之牽伸部 所牽伸的纖維束，包括：一送出部，係設在一牽伸部之一 對最終送出滾子的下游側，並裝設有一鉗夾滾子；一吸取 · 部，具有開設有吸取孔之一滑動面，該吸取孔係設置成相 對於該送出部之一鉗夾點朝向纖維束移動方向之上游側延 伸；及一可透氣之皮圈（air-permeable apron)，係形成送出 部，當其接觸滑動面時，即可轉動；該吸取部具有分別對 應於複數錠子單元（spindle unit)之複數吸取孔，該等複數 吸取孔則共同接通於一共通導管，藉多數抽吸裝置令該共 通導管內保持爲負壓。 1278543 因之’因該導管內爲負壓，故吸取部之複數吸取孔內即 產生吸取作用。又，因導管係以多數抽吸裝置維持負壓， 故即使某些吸取裝置有故障甚或停止，由於其他正常之吸 取裝置仍產生負壓，故精紡所得之線的品質仍可保持在容 許範圍之內。 μ 實施方式 · 茲以第1〜6圖說明本發明之一代表性實施例。第i圖爲 顯示在一纖維束集束裝置之一導管（duct)、吸取裝置與吸取 部間的關係之槪要平面圖，第2圖爲部分剖面的槪要側視 · 圖，顯示一吸取裝置之一側。第3圖爲吸取裝置部分槪圖 ，頂部滾子未予繪出，用以表示纖維束集束裝置之諸吸取 部與諸底部鉗夾滾子兩者間之關係。第4a圖爲在一鉗夾點 上、於纖維抽出方向中所見（自纖維束於牽伸裝置中之移動 方向的前方所見）之纖維束集束裝置槪圖。 如第2圖所示，作爲一牽伸部之一牽伸裝置11者，爲三 線式之結構，裝設有一前方底部滾子1 2、一中間底部滾子 1 3、及一後方底部滾子1 4。前方底部滾子1 2係以一構成鲁 機座框之滾子架1 5支持在預定位置上，中間及後方底部滾 子1 3及1 4則係經由固定在滾子架1 5之支持托架1 3 a及 1 4 a的中介作支持，故可在縱長方向作位置之調整。支持 托架1 3 a、1 4 a係藉穿通於滾子架1 5所開設之伸長孔的螺 栓及螺帽（未全部圖示）予以固緊在預設位置上。一底部裙 (bottom apron)16係圍繞一底部張力器17與中間底部滾子 1 3作捲繞。 -8- 1278543 一前方頂部滾子1 9、一中間頂部滾子2〇及一後方頂部 滾子2 1，在各自對應前方底部滾子1 2、中間底部滾子13 及後方底部滾子1 4的位置處透過頂部滾子支持構件之中 介由一加重臂（weight arm)l8所支持。各個頂部滾子19〜 21係支持於一雙錠子單元（two-spindleunit)中。前方底部 “ 滾子1 2與前方頂部滾子1 9構成牽伸裝置1 1之一對最終輸 · 送滾子。 加重臂18上配設有一桿件（lever) 18a，以更可轉動到一 加壓位置及一釋放位置。在桿件1 8a設置在第2圖所示的 · 桿件1 8a抵靠在加重臂1 8之框架1 8b的加壓位置之狀況， 保持一鎖定狀態，其中加重臂1 8所支持之頂部滾子1 9〜 2 1，均係位在將它們朝底部滾子1 2、1 3及1 4作加壓的加 壓位置（精紡位置）。在桿件1 8 a由第2圖所示之位置轉動 至上方的釋放位置之狀況，鎖定狀態即解除。 如第2圖所示，纖維束集束裝置3 0係配設在牽伸裝置 1 1 一對最終輸送滾子之下游側。纖維束集束裝置3 0設有 :一輸送部3 1 ;作爲吸取部S之吸取管3 2與3 3 ;及作爲 鲁 透氣構件之一透氣皮圈34。該輸送部31係由：一底部鉗夾 滾子3 5 a，係形成在平行於前方底部滾子1 2之一轉動軸3 5 上；及一頂部鉗夾滾子3 1 a，係經可透氣皮圈3 4之中介而 對底部上方滾子3 5 a作加壓；等兩者所組成。 如第4a圖所不，在此一實施例之纖維束集束裝置30中 ，如同牽伸裝置1 1之頂部滾子1 9〜2 1般，頂部鉗夾3 i a 係以加重臂1 8經由一支持構件3 6之中介（如第2圖及第5 -9- 1278543 圖所示）而被支持於每二個錠子中。應注意者，乃此實施例 中，支持構件3 6與前方頂部滾子1 9之支持構件係一體形 成者。 另一方面，在纖維束集束裝置3 0之底側，配置於彼此相 鄰的牽伸裝置1 1之滾子架1 5間一半的錠子，亦即，4個 — 錠子，係構成1組單元。如第3圖所示，在沿機器機座之 -縱長方向上依預設間隔所配設之該等滾子架1 5中間位置 處，一支持臂3 8在其底座端以沿機器底座之縱長方向作延 伸之一支持樑3 7作支持的狀態來配置，而一轉動軸3 5係 φ 在滾子架1 5及支持臂3 8間作支持。 如第4b圖所示，轉動軸3 5係以對應於複數個錠子（此實 施例爲4個）的預設長度而形成，而一軸承3 9可固定在其 任何一端。之後，軸承3 9係配裝於端部插塞40內，且如 第4 a圖所示，端部插塞4 0係以滾子架1 5與支持臂3 8上 所設之支持部15a與38a支持在啣接部40a中，因之，轉 動軸3 5係在滾子架1 5與支持臂3 8間被可轉動的支持。支 持部1 5 a與3 8 a形成可以支持安裝在兩相毗鄰轉動軸3 5 φ 之端部上的兩個端部插塞4 0。 支持部15a係以一固定於滾子架15之塊狀物（block)而形 成，且具有在機器底座之前側上向上傾斜延伸之複數個啣 接凹口。而支持部38a亦具有在機器底座之前側上向上傾 斜延伸之一啣接凹口。之後，端部插塞4 0具有一啣接部 40a，可和該等啣接凹口作啣接，且形成可以利用一單一動 作即可在啣接部40a相對於支持部15a與38a卡合在適當 -10- 1278543 位置。 ‘ 轉動軸3 5在其縱長之中心處具有一齒輪4 1，其係配置 成可以與轉動軸3 5 —體轉動。如第3圖所示，前方底部滾 子1 2在相對於該齒輪4 1之位置上具有一齒輪部1 2 a。又 ’與齒輪部1 2 a及齒輪4 1嚙合之一中間齒輪4 3係以一支 持臂42被可轉動地支持，支持臂42之底座端係固定於類 -似支持臂3 8之支持樑3 7。此即，前方底部滾子1 2之扭力 係介由齒輪部1 2a、中間齒輪43及齒輪4 1傳輸至轉動軸 3 5 〇 · 如第1、2圖所示，在精紡機之機器底座內，用於纖維束 集束裝置之導管44設置成沿機器底座之縱長方向（垂直於 第2圖所示平面之方向）延伸。如第1圖所示，複數支導管 44設置成沿精紡機之機器底座縱長方向延伸。此實施例中 ，各導管44之長度係對應於一側爲24個錠子單元、兩側 共48個錠子單元者。各導管44中，用以保持負壓之複數 個（本例爲3個）吸取裝置45係經管件46連接於各導管44 。亦即，此實施例中，一個吸取裝置4 5係用於一組單元， 鲁 一組單元則由1 6個錠子單元所組成。吸取裝置4 5係由風 扇及馬達構成，其中風扇47a係以馬達47驅動。如第2圖 所示，導管44係配置在牽伸裝置1 1之上方後側及在精紡 機之機座中心位置處，而吸取裝置4 5則配設在導管44的 下方。如第1圖所示，4個吸取部S係對每4個錠子單元 設置成平行於導管4 4延伸，並係經由連接管4 8連接於導 管44。各連接管48在中央處具有一摺箱（bellows)部49( -11- 1278543 僅示於第2圖）。第1圖中，吸取管3 2與3 3係共同地顯示 爲吸取部S，吸取管3 2與3 3均分別設有複數之吸取孔， 係以虛線繪示，並將於下述。 如第6圖所示，連接管4 8之前端形成有啣接孔48 a與 4 8b，則吸取管3 2與3 3乃可卸下地裝附於該啣接孔內。此 ·· 外，吸取管3 2與3 3之第1端部亦可卸下地裝附於連接管 . 4 8之右側與左側，而吸取管3 2與3 3之第2端部則係啣接 於端部插塞40。又者，接合有軸承3 9之啣接孔40b係形 成在端部插塞40上。第6圖爲部分槪要斜視圖，用以繪示 φ 吸取管3 2與3 3固設於連接管4 8 —側之狀態。 如第3圖所示，吸取管3 2具有一滑動面3 2b，該滑動面 3 2b具有複數個裂縫狀的吸取孔3 2a，該等吸取孔係在纖維 束F (Fleece，絲絨）的移動方向之上游側延伸而底部鉗夾滾 子3 5 a之鉗夾則在那之間。吸取管3 3亦具有一滑動面3 3 b ，該滑動面3 3 b具有複數個裂縫狀的吸取孔3 3 a，該等吸 取孔係在下游側作延伸。然後如第3、5圖所示，就纖維束 之移動方向而言，吸取管3 2係配置成在底部鉗夾滾子之·鉗 φ 夾點的上游側，而吸取管 3 3則係配置成在那的下游側。 注意者，乃在第3圖中，透氣皮圈3 4係以鏈線繪示，如此 ，即可容易見及吸取孔3 2 a及3 3 a。 吸取管3 2 以這樣的構成來形成，使得它們可引導透氣 皮圈34並將之帶到前方底部滾子12與前方上部滾子19之 鉗夾點附近處。吸取管3 3配置成自透氣皮圏3 4所送出之 纖維束F係以某個前羅拉包圍角（fleece angle)作轉向。「 -12- 1278543 前羅拉包圍角」乙詞之含義，係指：連接弧面之曲度中心 及鉗夾點之線段與連接曲度中心及用於纖維束F之抽出點 之線段所作成之角度，已經通過鉗夾點之纖維束F(絲絨） 沿該弧面被導引至抽出位置。透氣皮圈3 4係捲繞成可部 分接觸吸取管3 2與3 3，並有部分接觸底部鉗夾滾子3 5 a ，且當滑動至滑動面3 2b、3 3 b時，因底部鉗夾滾子3 5 a轉 · 動，故其亦轉動。此實施例中，透氣皮圈3 4係以可保持適 當透氣性之編織纖維所形成。 在第2、4a···等圖中，於各吸取管33之下部附近，配置 鲁 有單一型式氣動裝置之吸取噴嘴5 0的前端部，該氣動裝置 係在線截斷時，用以吸取自牽伸裝置1 1所送出之纖維束F 。吸取噴嘴5 0之底座端部係在全部錠子間連接到共用之 吸引導管51。 其次，說明上述構造之裝置的動作。 當精紡機動作時，纖維束F係行經牽伸裝置1 1之底部滾 子1 2〜1 4，與上部滾子1 9〜2 1等之間而可作牽伸，之後 ，引導至纖維束集束裝置30。輸送部31之上方鉗夾滾子 φ 3 1 a係以略高於前方底部滾子1 2與前方上部滾子1 9之表 面速度的速度作轉動；在適當張力下，行經輸送部3 1之鉗 夾點後，纖維束F即轉向並朝下游移動，同時經歷加撚 (twisting) 〇 又，導管44之吸取作用係經連接管48運用於吸取管32 與33，而滑動面32b與33b所形成之吸取孔32a與33a之 吸取作用係經透氣皮圈3 4運用於纖維束F上。之後，纖維 -13- 1278543 束F乃移動，同時’在對應於吸取孔32a與33a之位置處 ’ ，被吸取及收集。因吸取孔32a與33b係分別位在送出部 3 1之鉗夾點的上游側與下游側，故即使是行經鉗夾點之後 ，纖維束F在吸取作用下仍爲移動並被收集。結果，在行 ‘ 經鉗夾點後，各纖維束F兩端上之纖維分離（fiber separation) 即可予以約制而抑制絨毛（fluff)及廢棉之產生，因之，就 . 線的品質而言，可達成實質之改善。 各導管44係藉複數個（3個）抽吸裝置45保持爲負壓。因 此，即使有一個抽吸裝置45因發生異常（故障）而停止未動 肇 作，惟尙有其他各抽吸裝置4 5仍可用以保持導管44內之 負壓達一預設之水準，藉以確保用以收集纖維束F的吸取 孔3 2a與3 3 a之吸取作用。倘在未有吸取作用下仍持續進 行精紡，則線的品質必將變差。但是，本發明此一實施例 有別於傳統裝置者，係即使有一個抽吸裝置4 5因故障而停 止時，吸取孔3 2a與3 3 a之吸取作用仍不間斷，故可使用 線之品質不致變差。 此一實施例具有以下之各種優點： φ a)對應每個錠子單元配備在牽伸後在纖維束F上施加吸 取作用的吸取管3 2與3 3，係經該等連接管4 8連接於該等 導管44，且各導管44係經複數抽吸裝置45保持爲負壓。 因之，不同於傳統裝置者，係當有部分抽吸裝置4 5因異常 而停止時，本實施例由於尙有其他之抽吸裝置仍可維持負 壓，故吸取孔3 2a與3 3 a仍可保持其吸取作用，故而可確 保精紡所得之線的品質在可容許之限度內。 -14- 1278543 件 b )複數個導管4 4係設置成沿紡紗機之機座的縱長方%延〆· 伸。與單一導管44配置成沿紡紗機之機座的縱長方向延伸 之構造相比，複數導管4 4之安裝較易達成。又，當在紡紗 機之機座的某一中點設置一柱狀物（p i 1 la r )時，藉該柱狀物 即可輕易的避免該導管44之干涉。 〇在使用單一支吸取管32、33，用以將吸取作用運用於 · 多數錠子單元之纖維束F上的構造中，較靠近連接管48之 吸取孔32a、33a的吸取作用，及離開連接管48較遠之吸 取孔3 2a、3 3 a的吸取作用，兩者間之差異自然較大。又， 鲁 除了諸錠子單元間之吸取作用有差異外，因單一吸取管3 2 、3 3之長度較長，故其對於機座之裝卸操作性亦較差，且 保養亦不易，故單支吸取管32、33所具之吸取孔32a、33a 以用於4個錠子單元爲宜。此狀況中，連接管4 8將增加。 但是，連接管4 8並不連接於吸取裝置4 5，而係連接於導 管44。因此，即使連接管48有所增加，但是在相同條件 下，其仍可輕易的連接該等吸取管3 2、3 3及該等導管44 ，因此，以各精紡單元精紡所得之線的品質變化乃甚輕微 · 〇 d) 用於纖維束集束裝置之諸導管44，係獨立於一氣動導 管5 1而設置。因之，可保持導管44內之負壓一預設値， 而毋關於吸取裝置4 5之尺寸增加。 e) 諸導管44係配設在牽伸裝置11之後側與上方，及在 紡紗機之機座的中心處，且諸連接管48係配置成在底部滾 子1 2〜1 4之上方作延伸。因此，在氣動導管5 1係設成依 -15- 1278543 、 ^ 紡紗機之機座縱長方向作延伸的精紡機中，較容易固定用 ' 於導管44之配置位置。又，連接導管44與吸取管32、33 之連接管4 8亦不易妨礙其他構件，故有助於固定之操作及 維護之作業。 ’ f) 吸取管3 2、3 3係對稱的固定在各連接管4 8之兩側， 故假設係設成相同數量之吸取孔32a、33a，以比較僅在各 _ 連接管4 8之一側固設吸取管3 2、3 3之狀況而言，吸取孔 3 2a、3 3a間之吸取作用的差異將可減少。又，亦可有助於 更換透氣皮圈34之作業。 φ g) 由於吸取孔3 3 a係設在鉗夾點之下游，故其收集效果 可傳達至鉗夾點之上游某種程度，且直到纖維束F抵達鉗 夾點時，可抑制該纖維束F之擴散。結果，可更進步改善 集束功效。 上述之實施例並非不可作其他之技術性變更與修改，以 下所述之構造亦屬可行。 於諸吸取裝置中，可設用以檢知異常之異常檢知裝置。 基於來自異常檢知裝置所檢知之異常信號，即可令產生異 φ 常之該吸取裝置停止。又，亦可採用一種配置，其中連接 到與異常的吸取裝置相連的導管的其它正常吸取裝置係以 增強其吸取性能的方式來驅動。例如，如第1圖之鏈線所 示，各吸取裝置45係設有異常檢知之感知器52，用以作 爲馬達47之異常檢知裝置。異常檢知感知器52例如可爲 用於馬達47之驅動軸的轉速感知器。又，各馬達47建構 成能以一控制裝置（未圖示）作單獨之控制。則基於來自異 -16- 1278543 常檢知感知器5 2之異常檢知信號，控制裝置即停止業已產 生異常之吸取裝置4 5，並遂行控制加強連接於導管44之 其他正常吸取裝置45的性能。如是，當卸紗（doffing)停止 後，發生異常之該吸取裝置45即可作修理。倘吸取裝置45 中有任何一個產生了異常，即使是該異常之吸取裝置停止 ^ 運作，但導管44內之負壓仍係保持在可容許之限度內，故 — 直到一預設之卸紗時間前，仍可持續作精紡並保持精紡所 得之線的品質爲穩定狀況。 倘所採用之構造爲，其中之控制係用以控制連接同一導 · 管44之各馬達47而非爲對各馬達47作單獨控制之構造時 ，則當吸取裝置4 5有任何一個產生異常時，即可增強其他 吸取裝置45之性能。例如，當馬達47藉由變換器（inverter) 予以驅動時，爲每個連接於相同一支導管44之馬達47設 置一變換器。此狀況中，比較各馬達47作單獨控制之構造 而言，在控制與構造上均較簡化。 亦可採用一種配置，其中用以檢知吸取裝置異常之異常 檢知裝置，係設成基於來自異常檢知裝置之異常檢知信號 # 而用以停止全部的錠子單元所作之精紡動作。例如，如第1 圖之鏈線所示，各吸取裝置4 5係設有一異常檢知感知器5 2 作爲馬達47之異常檢知裝置。則，基於來自異常檢知感知 器5 2之異常檢知信號，用於控制紡紗機停止動作之控制裝 置啓動控制以停止紡紗機之操作。在紡紗機之操作已經停 止之後，異常之該抽吸裝置4 5乃可作維修。此狀況中，當 有任一吸取裝置4 5發生異常時，以全部錠子單元所作之精 -17- 1278543 紡即基於來自異常檢知裝置之異常檢知信號而停止，故可 防止紡紗機長時間處於異常狀態之動作。又，亦可在較早 之時間修理發生異常之該吸取裝置。 在一種所謂的單一錠子驅動型精紡機中，其中作爲精紡 機之複數錠子單元的複數錠子，係以複數獨立之馬達作單 ^ 獨之驅動，亦可採用一種配置，其中諸錠子單元之錠子的 -驅動係對應於接受來自導管44之吸取作用的吸取管3 2、 3 3，而該導管則係連接有發生了異常之抽吸裝置45。然後 ，直到一預設之卸紗時間前，其他的錠子單元仍持續作精 φ 紡。此狀況中，較諸於以所有錠子作精紡均爲停止之狀況 而言，在捲取期間停止精紡的精紡單元數量減少。 各導管4 4之長度並不一定對應於一側2 4個，兩側共4 8 個之錠子單元；其僅對應適當數量之錠子單元即可。該種 狀況中，對應8之倍數的錠子單元數量之導管長度爲佳。 除了將複數個導管44設置成沿紡紗機之機座的縱長方 向延伸之外，亦可僅配設一·支導管在紡紗機機座之整個長 度上延伸。 φ 導管44之位置不局限僅在牽伸裝置1 1之後側上方，亦 可設在牽伸裝置1 1之後方或後側下方。 除了將導管44以配置在精紡機兩側上之吸取管32、33

Field of the Invention The present invention relates to a fiber bundle collecting device and a spinning machine, and more particularly to a fiber bundle bundling device, which is disposed in For example, a downstream side of a drafting frame (draw section) of a spinning frame for collecting the fiber bundle drawn by the drafting device; and a spinning machine equipped with a fiber bundle bundling device . Prior Art Fig. 7 is a view showing an example of a spinning machine equipped with such a fiber bundle bundling device (see, for example, Japan; IP 2000-73 224A). On both sides of the frame of a spinning machine, a plurality of spinning stations 711 are installed, and the fiber bundle concentrating device is provided with suction profiles 72 and 7 3 having a plurality of suction cracks (suction holes). The suction cracking system is disposed corresponding to the spinning station 71, and a suction action is applied to the fiber bundle drawn by the drafting device. The suction profiles 72 and 73 are connected to the suction devices 76 and 77 via suction tubes 74 and 75, respectively. The suction devices 76 and 77 are equipped with a fan 79 driven by a motor 78. In such a fiber bundle bundling device, the suction devices 76 and 77 are respectively provided for a fixed number of the spinning stations 7, so that the suction pressure difference acting on the suction cracks of the individual spinning stations 71 is reduced, The quality difference of the thread (thread, or yarn) obtained by worsted spinning can be reduced to an acceptable level. In addition, according to the JP-2〇〇〇_73 224A case, in order to monitor the vacuum state and the quality of the wire, a pressure measuring device is provided in each of the suction pipes 7 4 and 7 5, and in the event of a failure, the relevant The action of the machine part stops. -5- 1278543, compared with one structure, one of the suction channels common to all the spinning stations, > is kept in a vacuum state by a single vacuuming fan, and wherein the fiber bundle bundling device is connected to this channel, JP In the apparatus disclosed in the '2000-73224A case, the quality difference of the thread obtained by the spinning of each spinning station 71 is more easily reduced to an allowable level. However, the number of suction devices 7 6 and 7 7 for extracting the suction type 7 2, 7 3 of the spinning stations 7 1 for the grouping is limited to one, so when one is sucked When the device is faulty, it is not absorbed by the suction profile assigned to the suction device. As a result, if continuous spinning is continued, the quality of the wire obtained from the spinning station 7 1 without suction and the quality of the wire obtained from the spinning station 7 i under suction will be different. Beyond the allowable range. According to the above disclosure, the pressure measuring devices are respectively installed in the suction pipes 74, 75, and when a failure occurs, the operation of the relevant machine parts is immediately stopped to solve the above problems. However, in the publication, there is no indication of the mechanism for stopping the operation of the relevant part of the machine. In addition, when the spinning machine is not a so-called single-spindle-drive type, the mechanism for stopping the operation of the relevant parts of the machine is bound to be more complicated, and the cost of the company is increasing. Further, in the apparatus of the case of JP-2〇〇〇-73224A, each of the suction pipes 74 and 75 is connected to the suction profiles 7 2, 7 3 of the respective 8 spinning stations 7 1 . When the number of spinning stations 7 1 for receiving the suction profiles 7 2, 7 3 is increased, the suctioning action of the spinning station 7 1 closer to the suction tubes 7 4, 7 5 and the suction tube 74 are removed. The suction effect of the spinning station, which is far away from the 7th, will increase the difference between the two. As a result, it is easy to produce a change in quality in the number of -6- » 1278543 lines obtained by spinning a plurality of different spinning stations. In the apparatus disclosed in the JP-A No. 0-73 224A, the suction tubes 74 and 75 are directly connected to the suction devices 76 and 77, in order to reduce the worsted spinning for receiving the suction from the suction profiles 72, 73. The number of stations, if it is intended to increase the number of suction tubes 74, 75 connected to the suction devices 7, 6-7, will be more difficult. In addition, if the number of suction devices is increased without increasing the number of suction devices, the number of suction pipes connected to a suction device will not increase. SUMMARY OF THE INVENTION The present invention has been made in view of the problems of the prior art. One of the objects of the present invention is to provide a fiber bundle bundling device for a spinning machine, wherein even if an abnormality occurs in any one of the suction devices, the spinning can be performed by the suction of the abnormal suction device. The quality of the wire obtained by the spinning of the unit (the spinning station); and the quality of the wire obtained by the worst spinning under the suction of other suction devices; the difference between the quality of the two is kept within the allowable range.

The figure is shown to be supported in every two spindles. It should be noted that in this embodiment, the support member 36 is integrally formed with the support member of the front top roller 19. On the other hand, in the fiber On the bottom side of the bundle bundling device 30, half of the spindles disposed between the roller frames 15 of the drafting device 1 adjacent to each other, that is, four spindles, constitute one set of units. As shown in the figure, at the intermediate position of the roller frames 15 which are arranged at predetermined intervals along the longitudinal direction of the machine frame, a support arm 38 has a length along the base of the machine at the base end thereof. One of the directions is supported to support the beam 37 for support, and a rotating shaft 3 5 is supported between the roller frame 15 and the support arm 38. As shown in Fig. 4b The rotating shaft 35 is formed with a predetermined length corresponding to a plurality of spindles (four in this embodiment), and a bearing 39 can be fixed at either end thereof. Thereafter, the bearing 39 is fitted to the end. In the plug 40, and as shown in Fig. 4a, the end plug 40 is supported in the engaging portion 40a by the support portions 15a and 38a provided on the roller frame 15 and the support arm 38. The rotation shaft 35 is rotatably supported between the roller frame 15 and the support arm 38. The support portions 15a and 38a are formed to support the end portions of the two adjacent rotating shafts 3 5 φ The upper end plugs 40. The support portion 15a is formed by a block fixed to the roller frame 15, and has a plurality of engaging recesses which are inclined upwardly on the front side of the machine base. The support portion 38a also has an engagement recess that extends upwardly on the front side of the machine base. Thereafter, the end plug 40 has an engaging portion 40a that can be engaged with the engaging recesses, and is formed to be engageable with the supporting portions 15a and 38a at the engaging portion 40a by a single action. In the appropriate -10- 1278543 position. The 'rotating shaft 35' has a gear 4 1 at the center of its longitudinal length which is configured to be rotatable with the rotating shaft 35. As shown in Fig. 3, the front bottom roller 12 has a gear portion 1 2 a at a position relative to the gear 41. Further, an intermediate gear 43 is meshed with a gear portion 1 2 a and a gear 4 1 by a support arm 42 rotatably supported, and a base end of the support arm 42 is fixed to a support beam of the like-like support arm 38. 3 7. That is, the torque of the front bottom roller 12 is transmitted to the rotating shaft through the gear portion 12a, the intermediate gear 43, and the gear 41. 〇· As shown in Figures 1 and 2, in the machine base of the spinning machine The duct 44 for the fiber bundle bundling device is disposed to extend in the longitudinal direction of the machine base (perpendicular to the plane shown in Fig. 2). As shown in Fig. 1, the plurality of branch ducts 44 are disposed to extend in the longitudinal direction of the machine base of the spinning machine. In this embodiment, each of the conduits 44 has a length corresponding to 24 spindle units on one side and 48 spindle units on both sides. In each of the ducts 44, a plurality of (three in this example) suction means 45 for holding the negative pressure are connected to the respective ducts 44 via the pipe member 46. That is, in this embodiment, one suction device 45 is used for one set of units, and one set of units is composed of 16 spindle units. The suction device 45 is composed of a fan and a motor, wherein the fan 47a is driven by a motor 47. As shown in Fig. 2, the duct 44 is disposed at the upper rear side of the drafting device 1 1 and at the center of the frame of the spinning machine, and the suction device 45 is disposed below the duct 44. As shown in Fig. 1, the four suction portions S are provided so as to extend parallel to the duct 44 for every four spindle units, and are connected to the duct 44 via the connecting tube 48. Each of the connecting tubes 48 has a bellows portion 49 at the center (-11-1128543 is only shown in Fig. 2). In the first drawing, the suction tubes 3 2 and 3 3 are collectively shown as the suction portion S, and the suction tubes 3 2 and 3 3 are respectively provided with a plurality of suction holes, which are shown by broken lines, and will be described below. As shown in Fig. 6, the front end of the connecting pipe 48 is formed with engaging holes 48a and 48b, and the suction pipes 3 2 and 3 3 are detachably attached to the engaging holes. In addition, the first end of the suction pipes 3 2 and 3 3 can also be detachably attached to the right side of the connecting pipe. 4 8 and the left end, and the second end of the suction pipes 3 2 and 3 3 Connected to the end plug 40. Further, the engaging hole 40b to which the bearing 39 is joined is formed on the end plug 40. Figure 6 is a partially schematic perspective view showing the state in which the φ suction pipes 3 2 and 3 3 are fixed to the side of the connecting pipe 48. As shown in Fig. 3, the suction pipe 3 2 has a sliding surface 32b having a plurality of slit-shaped suction holes 3 2a which are moved by the fiber bundle F (Fleece). The upstream side of the direction extends and the jaws of the bottom jaw roller 3 5 a are between there. The suction pipe 3 3 also has a sliding surface 3 3 b having a plurality of slit-shaped suction holes 3 3 a which extend on the downstream side. Then, as shown in Figs. 3 and 5, in terms of the moving direction of the fiber bundle, the suction pipe 32 is arranged to be on the upstream side of the pinch Φ pinch of the bottom jaw, and the suction pipe 3 3 is arranged. On the downstream side of that. Note that in Fig. 3, the breathable apron 34 is shown by a chain line, so that the holes 3 2 a and 3 3 a can be easily seen. The suction tubes 3 2 are formed in such a manner that they can guide the breathable apron 34 and bring it to the vicinity of the clamping point of the front bottom roller 12 and the front upper roller 19. The suction tube 3 3 is arranged such that the fiber bundle F fed from the gas permeable raft 34 is steered by a certain front roller fleece angle. The meaning of the word "-12- 1278543 Front Roller" refers to the line segment connecting the curvature center of the curved surface and the clamp point and the line connecting the curvature center and the extraction point for the fiber bundle F. The angle, the fiber bundle F (velvet) that has passed through the clamping point is guided along the curved surface to the extracted position. The breathable apron 3 4 is wound to partially contact the suction tubes 3 2 and 3 3 and partially contact the bottom jaw rollers 3 5 a , and when sliding to the sliding surfaces 3 2b, 3 3 b, due to the bottom clamp The pinch roller 3 5 a turns and moves, so it also rotates. In this embodiment, the breathable apron 34 is formed of woven fibers that maintain proper air permeability. In the second, fourth, and the like, in the vicinity of the lower portion of each of the suction pipes 33, the front end portion of the suction nozzle 50 having a single type pneumatic device is disposed, and the pneumatic device is used for sucking self-trapping when it is cut off on the line. The fiber bundle F sent by the device 1 1 is stretched. The base end of the suction nozzle 50 is connected to the common suction duct 51 between all the spindles. Next, the operation of the device of the above configuration will be described. When the spinning machine is in operation, the fiber bundle F is drawn through the bottom rollers 1 2 to 14 of the drafting device 1 1 and the upper roller 19 9 to 2 1 and the like, and then guided to the fiber bundle. Cluster device 30. The upper clamping roller φ 3 1 a of the conveying portion 31 is rotated at a speed slightly higher than the surface speed of the front bottom roller 12 and the front upper roller 19; under the appropriate tension, the conveying portion 3 1 After the pinch point, the fiber bundle F is turned and moved downstream while undergoing twisting. Further, the suction of the pipe 44 is applied to the suction pipes 32 and 33 via the connecting pipe 48, and the sliding faces 32b and 33b are The suction of the formed suction holes 32a and 33a is applied to the fiber bundle F via the breathable apron 34. Thereafter, the fiber -13 - 1278543 bundle F is moved while being sucked and collected at a position corresponding to the suction holes 32a and 33a. Since the suction holes 32a and 33b are respectively located on the upstream side and the downstream side of the pinch point of the delivery portion 31, the fiber bundle F is moved and collected under the suction action even after passing through the pinch point. As a result, after the "clamping point", the fiber separation on both ends of each fiber bundle F can be controlled to suppress the generation of fluff and waste cotton, and thus, the quality of the wire. In fact, substantial improvements can be achieved. Each of the conduits 44 is held at a negative pressure by a plurality of (three) suction devices 45. Therefore, even if there is a suction device 45 that stops the operation due to an abnormality (fault), other suction devices 45 can be used to maintain the negative pressure in the conduit 44 to a predetermined level. The suction effect of the suction holes 3 2a and 3 3 a for collecting the fiber bundle F is ensured. If the worsted spinning continues without suction, the quality of the wire will definitely deteriorate. However, this embodiment of the present invention differs from the conventional device in that even if one of the suction devices 45 is stopped due to a failure, the suction of the suction holes 3 2a and 3 3 a is uninterrupted, so that the line can be used. Quality does not deteriorate. This embodiment has the following advantages: φ a) corresponding to each spindle unit equipped with suction tubes 3 2 and 3 3 for exerting a suction action on the fiber bundle F after drawing, which are connected via the connecting tubes 48 In the conduits 44, each of the conduits 44 is held at a negative pressure by the plurality of suction devices 45. Therefore, unlike the conventional device, when a part of the suction device 45 is stopped due to an abnormality, the present embodiment can maintain the negative pressure due to the other suction device, so the suction holes 3 2a and 3 3 a It can still maintain its suction function, thus ensuring that the quality of the wire obtained by the worsted is within acceptable limits. -14- 1278543 pieces b) The plurality of ducts 4 4 are arranged to extend along the longitudinal length of the frame of the spinning machine. The mounting of the plurality of conduits 4 is easier to achieve than the configuration in which the single conduit 44 is arranged to extend in the longitudinal direction of the frame of the spinning machine. Further, when a column (p i 1 la r ) is provided at a certain midpoint of the frame of the spinning machine, the interference of the duct 44 can be easily avoided by the column. The use of a single suction tube 32, 33 for the suction action to be applied to the fiber bundle F of the majority spindle unit, the suction effect of the suction holes 32a, 33a closer to the connection tube 48, and the exit connection The suction effect of the suction holes 3 2a and 3 3 a of the tube 48 far away is naturally large. Moreover, in addition to the difference in the suction function between the spindle units, since the length of the single suction tubes 3 2 and 3 3 is long, the handling of the machine base is also poor, and the maintenance is not easy, so the single support The suction holes 32a, 33a of the suction pipes 32, 33 are preferably used for four spindle units. In this case, the connecting tube 48 will increase. However, the connecting tube 48 is not connected to the suction device 45 but is connected to the guide tube 44. Therefore, even if the connecting pipe 48 is increased, under the same conditions, the suction pipes 3 2, 3 3 and the pipes 44 can be easily connected, and therefore, the wire obtained by the worst spinning unit is worsted. The quality change is very slight. 〇d) The ducts 44 for the fiber bundle bundling device are arranged independently of a pneumatic conduit 51. Accordingly, the negative pressure in the conduit 44 can be maintained as a predetermined threshold, and the size of the suction device 45 is increased. e) the ducts 44 are disposed on the rear side and the upper side of the drafting device 11, and at the center of the frame of the spinning machine, and the connecting tubes 48 are arranged to be placed above the bottom rollers 1 2 to 14 extend. Therefore, in the spinning machine in which the pneumatic conduit 51 is extended in the longitudinal direction of the frame of the spinning machine, it is easier to fix the position of the conduit 44. Further, the connecting pipe 44 connecting the duct 44 and the suction pipes 32, 33 is also less likely to interfere with other members, and thus contributes to the operation of fixing and maintenance work. ' f) The suction pipes 3 2, 3 3 are symmetrically fixed on both sides of each connecting pipe 48, so it is assumed that the same number of suction holes 32a, 33a are provided to compare only one of the respective _ connecting pipes 48 In the case where the side suction pipes 3 2, 3 3 are fixed, the difference in the suction effect between the suction holes 3 2a, 3 3a can be reduced. Moreover, it can also help to replace the venting apron 34. Φ g) Since the suction hole 3 3 a is disposed downstream of the jaw point, the collection effect can be transmitted to some extent upstream of the jaw point, and the fiber bundle can be suppressed until the fiber bundle F reaches the jaw point The spread of F. As a result, the improvement of clustering efficiency can be improved. The above-described embodiments are not to be construed as being limited or otherwise. In the suction devices, an abnormality detecting device for detecting an abnormality may be provided. Based on the abnormal signal detected from the abnormality detecting device, the suction device that generates the abnormal φ can be stopped. Also, a configuration may be employed in which other normal suction means connected to the conduit connected to the abnormal suction means are driven in such a manner as to enhance their suction performance. For example, as shown by the chain line in Fig. 1, each suction device 45 is provided with an abnormality detecting sensor 52 for use as an abnormality detecting device of the motor 47. The abnormality detecting sensor 52 can be, for example, a rotational speed sensor for the drive shaft of the motor 47. Further, each of the motors 47 is constructed to be individually controllable by a control device (not shown). Then, based on the abnormality detecting signal from the hetero--16-1278543 normal detection sensor 52, the control device stops the suction device 45 which has generated the abnormality, and controls the performance of the other normal suction device 45 connected to the conduit 44. . If so, when the doffing is stopped, the suction device 45 which is abnormal can be repaired. If any of the suction devices 45 produces an abnormality, even if the abnormal suction device stops operating, the negative pressure in the conduit 44 remains within the allowable limit, so that - until a predetermined unloading time Before, the quality of the wire that is still sustainable for spinning and maintaining the worsted yarn is stable. If the configuration is such that the control is used to control the motors 47 connected to the same tube 44, rather than being configured to separately control each of the motors 47, then when any of the suction devices 45 produces an abnormality The performance of the other suction device 45 can be enhanced. For example, when the motor 47 is driven by an inverter, a converter is provided for each of the motors 47 connected to the same one of the conduits 44. In this case, the control and construction are simplified in comparison with the configuration in which the motors 47 are individually controlled. Alternatively, an abnormality detecting means for detecting an abnormality of the suction means is provided for stopping the spinning operation of all the spindle units based on the abnormality detecting signal # from the abnormality detecting means. For example, as shown by the chain line in Fig. 1, each suction device 45 is provided with an abnormality detecting sensor 5 2 as an abnormality detecting device of the motor 47. Then, based on the abnormality detecting signal from the abnormality detecting sensor 52, the control means for controlling the stop operation of the spinning machine starts control to stop the operation of the spinning machine. After the operation of the spinning machine has been stopped, the abnormal suction device 45 is repairable. In this case, when any of the suction devices 45 has an abnormality, the fine -17-1278543 spinning by all the spindle units is stopped based on the abnormality detecting signal from the abnormality detecting device, so that the spinning machine length can be prevented. The action of time is in an abnormal state. Also, the suction device in which the abnormality has occurred can be repaired at an earlier time. In a so-called single spindle driven type spinning machine, a plurality of spindles as a plurality of spindle units of a spinning machine are driven by a plurality of independent motors, and a configuration may be adopted in which the spindles are used. The spindle-driven system of the unit corresponds to the suction tube 3 2, 3 3 that receives the suction from the conduit 44, and the conduit is connected to the suction device 45 where the abnormality has occurred. Then, until the preset unloading time, the other spindle units continue to be finely φ spun. In this case, the number of the worsted units in which the worsted spinning is stopped during the winding is reduced as compared with the case where the spinning of all the spindles is stopped. The length of each of the conduits 4 4 does not necessarily correspond to 24 on one side, and there are a total of 48 spindle units on both sides; it only corresponds to an appropriate number of spindle units. In this case, the length of the catheter corresponding to the number of spindle units of 8 is better. In addition to providing a plurality of conduits 44 extending in the longitudinal direction of the frame of the spinning machine, only one of the support conduits may extend over the entire length of the spinning machine frame. The position of the φ conduit 44 is not limited to the rear side of the drafting device 1 1 only, but may be provided at the rear or rear side of the drafting device 1 1 . In addition to sharing the ducts 44 with the suction pipes 32, 33 disposed on both sides of the spinning machine, the ducts 44 may be formed as two rows of right and left sides extending along the longitudinal direction of the frame of the spinning machine. In addition to the configuration in which the rotating shaft 35 and the suction pipes 3 2, 3 3 are arranged to form a unit of four spindle units, an ingot adjacent to the roller frame -18-1278543 15 can also be used. The number of sub-units (that is, eight) corresponds to a group of cells, or a configuration in which two sub-units are configured as a group of cells or the like. Moreover, it is not often necessary for all units to have the same number of spindle units; it is also possible to make the number of spindle units between adjacent roller carriages I5 different from each other (for example, 6 and 2), thus providing Two corresponding units. In addition to the manner in which the suction tubes 3 2, 3 3 are used as separate members, the two suction tubes 3 2, 3 3 may be integrated as a means of aligning the top jaw rollers 3 1 a The side is curved as an arc. The suction tubes 3 2, 3 3 may also be aligned to the end of the side of the connecting tube 48 to be closed. In this case, the end plug 40 is not required to be used to completely close the end of the suction pipe 3 2, 3 3 , and the end plug only needs to be connected to the suction pipe. 3, 3 3 end can be, this will be helpful for production. In addition to forming a breathable apron in the form of woven or knitted fibers, it is also possible to use a perforated resin belt formed of rubber or an elastic resin. The suction pipes 3, 3 3 forming the suction portion may also be integrally formed with the connecting pipe. In addition to the suction holes 3 2 a, 3 3 b being disposed on the upstream side and the downstream side of the pinch point of the fiber bundle F, a configuration may be employed in which the suction hole is provided only on the upstream side of the jaw point. 3 2a. In this case, the suction pipe 33 having no suction hole 33a is used, and the manufacturing and fixing methods are substantially the same. Alternatively, the suction tube 3 3 may be omitted, and the breathable apron 3 4 may be wound between the suction tube 3 2 and the bottom jaw roller 3 5 a. As for the configuration for driving the gas permeable skin 圏 34, the following configuration can be employed. In addition to the suction tube 3 2, 3 3 and the bottom jaw roller 3 5 a, but the suction tube with an egg-shaped section is provided, the suction hole is formed at the preset position of the suction tube, and the breathable skin is -19- 1278543 The ring 3 4 is slidably wound around the outer circumference of the suction tubes. > Thereafter, the top jaw roller 3 1 a can be actively driven and driven while crimping the permeable apron 34, so that the breathable skin 34 can be driven. The configuration of the suction device is not limited to the one in which the fan 47a is driven by the motor 47, and for example, a vacuum pump (vacuum pumping) may be used. The vacuum pump / pump can be rotary or reciprocating pump. _ As for the pneumatic device, in addition to the single nozzle type, it may be a flute-shaped structure. The invention is not only applicable to the drafting device of the spinning machine, but also to the application of the drafting device of other types of φ spinning machines. As described in detail above, according to the present invention, even if any one of the suction devices generates an abnormality, the quality of the wire obtained by spinning the worsted spindle unit (spindle station) under the suction of the suction device; The quality of the thread obtained from the worsted spinning spindle unit; the difference in quality between the two can still be kept within the allowable limits.
