200916619 九、發明說明 【發明所屬之技術領域】 本發明係有關於一種申請專利範圍第1項前言部份中 所定義之型式的裝置。 【先前技術】 此種型式之裝置特別是應用於稱爲精紡編織彳幾（ Spinning Knitting Machine)的編織機上（例如說 PCT WO 2004/07906 8 > P C T W Ο 2 0 0 7 / 0 9 3 1 6 5 A 2、 PCT WO 2007/093 1 66 A2)。這些機器的不同點在於編織 織物並不是由傳統的紡紗製成的，而是由纖維條、翼錠帶 或類似之現存纖維材料所製成，這些材料要在針縫部形成 前先由紡紗技藝中所知悉的牽伸系統加以拉伸成預定的g 細程度’且其等在離開牽伸系統後會成爲一種適合於由紡 紗裝置加以輸送至習知之編織機或類似者的狀態。 在一特佳的實施例中，該紡紗裝置包含有一撚元件及 一連接至該元件上的輸送管或紡紗管。因此，纖維材料會 轉換成具有真正撚捻部的臨時紗，其可以在相當長的距離 內良好地輸送。在快要由編織針或類似者加以處理之前， 該等撚捻部會重新被去除掉（假撚原則），以得到極度柔 軟的編織織物。 但是’另一種情形是，該紡紗裝置亦可構造成能形成 永久性僵硬的紗線，特別是稱爲非傳統紗線，且係形成爲 供例如氣流精結裝置用者（例如比較EP 1 5 1 8 949 A2及 200916619 EP 1 82 6 299 A2 )。此種型式的紗線也會具有一些撚捻部 或是捲曲部，但是是如同絞紗或是再繞紗，而不是傳統觀 念中的紗線。此紡紗程序最好是調整成，如同前述的臨時 紗一樣’能提供可滿足於所需之輸送目的的充份密實的紗 束’但仍能得到充份柔軟的編織織物。 在具有多個編織系統的圓編織機中，可以方便地將牽 伸系統與編織系統間相當長的距離結合在一起。在此種情 形中’最好在這些牽伸系統與編織系統之間設置至少二個 紡紗裝置，且該等裝置係以相串接的形態一個設置於另一 個的後方’並且每一者均係由一紡紗元件及一紡紗及輸送 管所構成。 在處理以上述方式導入至編織機內的纖維材料時，有 一項缺點是，即是黏附於纖維材料上並隨之移送的灰塵顆 粒、纖維粒節、纖維球、短纖維及異物纖維、以及其他鬆 散的異物物體，可能會造成編織織物上的誤差，並弄髒針 縫部成形元件。不同於一般的紡紗，並沒有捲曲機或類似 者存在’以供辨識纖維材料內的雜質及其他瑕疵，並藉由 切割而後接合纖維材料以選擇性地修正之。 在將已延伸纖維材料加以導引至其他機器的作業站內 時亦會發生相同的缺點。 【發明內容】 由此點開始，本發明的技術標的是要組構出一開始所 提到的裝置’以使得其可以在纖維流進入至各機器之作業 -5- 200916619 站之前，有效地清潔之，避免不必要的纖維飛屑’並係製 做成具有可依據製造及作業成本來調整的進入及排出流（BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device of the type defined in the preamble of claim 1 of the patent application. [Prior Art] This type of device is particularly applied to a knitting machine called a Spinning Knitting Machine (for example, PCT WO 2004/07906 8 > PCTW Ο 2 0 0 7 / 0 9 3 1 6 5 A 2. PCT WO 2007/093 1 66 A2). The difference between these machines is that the woven fabric is not made of conventional spinning, but is made of fiber strips, wing strips or similar existing fibrous materials that are to be spun before the needle seam is formed. The drafting system known in the art is stretched to a predetermined degree of g' and which, after leaving the drafting system, becomes a state suitable for transport by a spinning device to a conventional knitting machine or the like. In a particularly preferred embodiment, the spinning device comprises a weir element and a transfer tube or spinning tube attached to the element. Therefore, the fibrous material is converted into a temporary yarn having a true crotch which can be transported well over a relatively long distance. These crotch parts are removed again (pseudo-twist principle) before being processed by a knitting needle or the like to obtain an extremely soft woven fabric. However, 'in another case, the spinning device can also be configured to form a permanent stiff yarn, in particular referred to as a non-traditional yarn, and is formed for use by, for example, a flow consolidation device (eg, comparing EP 1 5 1 8 949 A2 and 200916619 EP 1 82 6 299 A2 ). This type of yarn also has some crotch or curl, but it is like a skein or a rewind, rather than a yarn in a conventional concept. Preferably, the spinning sequence is adjusted to provide a densely woven yarn bundle that satisfies the desired conveying purpose, as in the case of the temporary yarn described above, but still provides a sufficiently woven fabric. In a circular knitting machine having a plurality of knitting systems, it is convenient to combine the considerable distance between the drafting system and the weaving system. In this case, it is preferred to provide at least two spinning devices between the drafting system and the weaving system, and the devices are disposed one behind the other in a tandem configuration and each It consists of a spinning element and a spinning and conveying tube. One of the disadvantages in handling the fiber material introduced into the braiding machine in the manner described above is that it is adhered to the fibrous material and transported along with dust particles, fibrous pellets, fiberballs, staple fibers and foreign fibers, and others. Loose foreign objects can cause errors on the woven fabric and stain the stitch forming elements. Unlike conventional spinning, there is no crimper or the like present to identify impurities and other imperfections in the fibrous material and to selectively modify the fibrous material by cutting and then bonding. The same drawbacks occur when the extended fiber material is guided into a work station of another machine. SUMMARY OF THE INVENTION Starting from this point, the technical scope of the present invention is to assemble the device mentioned at the outset so that it can be effectively cleaned before the fiber flow enters the operation of each machine -5 - 200916619 station. In order to avoid unnecessary fiber flying debris, and to make it into the inlet and outlet streams that can be adjusted according to manufacturing and operating costs (
Intake and Outtake Flows)。 此問題可使用申請專利範圍第1項中的特徵結構來解 決之。 本發明的優點是在於藉由一設置於一紡紗及輸送管的 二部位之間，或是在二紡紗裝置之間，並且形成爲一封閉 的系統，且可配合空氣的吹送及/或吸收來作動的清潔站 ’其可以達成碎裂纖維飛屑及其他雜質的有效去除。因此 ’可大幅度地降低對於作業過程的干擾，同時可避免纖維 球、灰塵及其他雜質在該機器內的堆積。再者，儘管是使 用封閉式的流動系統，對於纖維材料之輸送至作業站所需 的輸送作業並不會受到影響。 本發明的其他優點可自申請專利範圍附屬項中得知。 下面將配合於所附圖式’針對實施例來說明本發明。 【實施方式】 第1圖示意地顯示出根據本發明的裝置，係供應用於 最好是編織機的機器內’在此實施例中特別是一種圓編織 機’其包含有一具有編織針2的針筒1、一關連於該等編 織針2的凸輪總成3、以及一設有線導孔5的線導4。再 考，第1圖中顯示出該編織機的一編織系統，在該系統中 ，編織針2可由凸輪總成3加以舉升至—適合於接收纖維 材料6的接收位置，該纖維材料6會移動通過該線導孔5 -6 - 200916619 該纖維材料6是由每一編織系統經由各自之牽伸系統 7來加以製成的，在第1圖中僅顯示出該牽伸系統內的二 個拉引滾輪7a，且可供一纖維條、翼錠帶或類似者以未顯 示出的方式加以導入其內。在此實施例中，來自牽伸系統 7並被拉伸至所需之纖細程度的纖維條會被導入至一紡紗 裝置8內，而該紡紗裝置包含有一紡紗元件9，其在此例 中是由壓縮空氣Ρ ϋ加以驅動的撚捻元件，以及一連接至 其上的紡紗及輸送管。在此紡紗及輸送管1 0上連接著一 第二紡紗及輸送管1 1，其出口末端係中止於該線導孔5內 。特別有利的是將第二紡紗及輸送管1 1的入口末端連接 至一第二紡紗元件1 2 ’而使得紡紗元件9及紡紗及輸送管 1 〇能構成該紡紗裝置8，而紡紗元件1 2及紡紗及輸送管 1 1則構成一第二紡紗裝置1 4，其係沿著纖維材料6的輸 送方向設置於紡紗裝置8後方。 紡紗裝置8係用來將由牽伸系統7所提供的纖維束轉 變成一具有真實撚捻部的臨時紗15，該等撚捻部可自第二 紡紗裝置14處一直維持至線導4處。在線導4位於纖維 輸送方向的後方，該等撚捻部會因假撚效果之故而被大致 上鬆解開，以使得被導入至編織針2內的纖維材料6是大 致上沒有撚捻的纖維材料。 前述型式的圓編織機係可自例如文獻 PCT WO 2004/079068 及 DE 10 2006 006 502 Α1 中得知， 其等係在此加以提到，以結合於本文的內容內，避免重覆 200916619 說明。 根據本發明，一清潔站1 6設置於紡紗及輸送管1 〇的 出口末端及紡紗兀件1 2的入口末端之間，係連接至一收 集導管17上，用來自纖維流中清理及移除雜質。在本文 中，“清潔”應理解爲代表在站1 6內能儘可能地將纖維 流中所攜行的所有雜質，例如纖維球、灰塵、短纖維、線 頭、殼片等，加以清除，而不會損及纖維流或臨時紗1 5 本身，或是阻礙其移動至線導4內。清潔站1 6是連接至 紡紗及輸送管1 〇的出口末端及紡紗元件1 2的入口末端， 以使得該站可與其等共同形成一個實質上封閉的流動系統 ，亦即自纖維流上分離出來的雜質會被直接導入至收集導 管17內，而不會到達外部環境內。， 根據第2圖至第5圖，清潔站16最好包含有一由外 殼加以包圍的撚捻腔室16a，以及一清除管16b，其亦可 如第4圖般製做成圓錐狀。爲能對清潔站1 6加以維護及 修理，其係藉由例如以一撓性結合部1 8 (第1圖）或是透 過樞轉式連接（第4圖及第5圖）而連接至收集導管17 上，其也可以讓根據第4圖及第5圖的樞轉式連接做成一 設置於撚捻腔室16a與清除管16b之間的鉸鏈19，其在第 4圖中所示是關閉位置，而在第5圖中則是開放位置。如 果需要的話，此配置亦可設置成讓清潔站1 6或撚捻腔室 1 6a與後方的紡紗裝置1 4 一起樞轉或滑移。 撚捻腔室1 6a是實質上形成爲一封閉腔室，在流動上 是連接至結紗及輸送管1 0及紡紗元件1 2上。該腔室是用 200916619 來在纖維材料或臨時紗1 5進入至下一紡紗裝置1 4之前， 將空氣攜行的纖維、雜質等等自經由輸送管1 〇進入其內 的纖維材料內釋放出來，並且將他們經由清除管1 6b導入 至收集導管1 7內。 根據第2圖及第3圖，撚捻腔室1 6a最好是另外設有 一連接管20或2 1，例如說垂直朝向上方或是斜向地朝向 下方，該連接管係設置成與紡紗及輸送管1 0相切。壓縮 空氣ρϋ會經由連接管20、21導入至撚捻腔室i6a內，用 以維持並改善該分離過程。經由連接管20、2 1導入的壓 縮空氣亦會將進入至撚捻腔室1 6 a內的纖維材料沿著旋轉 的方向加以驅動’如第2圖至第5圖中箭號所示，而鬆散 的纖維及類似者會同時被驅入至清除管16b內。如此以及 達成以示意標示之雜質2 2，例如纖維飛屑、灰塵等等，之 纖維流中自然而高效能地分離，如第2圖至第4圖中示意 顯示的。 自纖維流上分離開的雜質2 2可經由清除管1 6 b及收 集導管1 7來加以移除’而該收集導管則是結合至例如圓 編織機的中央吸引裝置上，以使得負壓力pu得以充注其 內，並選擇性地充注於清除管1 6 b內。另一種方式是，收 集導管17可以連接至一壓縮空氣源，以供在其內產生過 壓力ρϋ，其可將雜質22沿其攜行，並將其等導引至一中 央收集點處。由於提供至撚捻腔室16a及清除管16b內的 壓力是相當的低，因此清潔站1 6所需要的額外能量需求 也很低。 -9- 200916619 根據本發明的第二實施例是顯示於第6圖中，其中相 同的零件是以與第1圖至第5圖中相同的參考編號加以標 示。不同於第1圖至第5圖，收集導管1 7的後側延伸出 一連接管17a。此係中止於一吸引噴嘴17b，而其入口末 端是設置成緊鄰於牽伸系統7，特別是該拉引滾輪對7 a中 的上方及/或下方滾輪，以使得該處所所產生的纖維飛屑 亦可被輸送至收集導管17內。吸引噴嘴Hb可以很方便 地結合一鼓風噴嘴23，其係由過壓力ρϋ加以驅動，並且 藉由之可以更進一步改善拉引滾輪對7a之區域內的清潔 效果。 第ό圖進一步顯示出此例中的第二紡紗及輸送管i i 具有較第一紡紗及輸送管1 〇爲小的直徑。因此，紡紗管 1 0內被牽引的容積相對於紡紗管11內被牽引的容積會增 高’因此也會增強清潔及雜質移除的效態。再者，在此裝 置的穩定運轉時，亦即在線聯結上去後，紡紗噴嘴9內的 過壓力pti可以減低或設爲零値，在此情形下，清潔的作 用大致上係僅依收集導管1 7內的負壓力來進行，可以節 省能量。 再者’第6圖顯示出清潔站16包含有一撚捻腔室i6c ’與第1圖不同的是其包含有一向下突出，最好是形成爲 圓錐形的結合件’其設有一·小的清潔或吸引開口 1 6d。如 同第1圖一樣，此結合件可供來自纖維流的雜質進入，而 清潔開口 1 6d則可讓遠離收集導管1 7處的空氣被吸入， 如箭號所示。因此’雜質會被向上吸入，而可防止其掉落 -10 - 200916619 通過開口 1 6d。整體而言，根據第6圖的裝置係構成一實 質上封閉的流動系統。 另一種方式是，可在清潔開口 16d處結合一壓縮空氣 連接部’以產生類似於第2圖及第3圖的流動關係。 根據本發明之裝置的第三實施例是顯示於第7圖中， 紡紗及輸送管1 0同樣具有大於紡紗及輸送管1 1的直徑。 清潔站內的負壓力較高（pu>>)，具有框紡紗（Frame Spinning)及挖'集防紗（Compact Spinning)所習用之負 壓力的大小級數。紡紗元件9是位於距離拉引滾輪7a最 小距離處’並突伸進入其內的空間內。在紡紗及輸送管1 0 內會因此而造成一股強的吸引流，其可保持拉引滾輪7a 清潔。紡紗構件9內的空氣壓力可確保紡紗及輸送管1 〇 必要的旋轉，以使得纖維飛屑可自撚捻腔室1 6a內分離出 來。此裝置具有較少的零組件。 以方式爲之可以有利地讓此機器啓動階段時的負壓力 較低。 紡紗元件1 2內的壓力可以方便地調整成讓紡紗張力 高到足以轉動臨時紗1 5而不會碰觸到紡紗及輸送管丨〇的 壁部。透過此種型態的配置，紡紗裝置8可以有高的總長 度L ’而不會不利地影響到紡紗過程，因此防紗裝置8可 具有的長度L> K，其中K是紡紗裝置1 4的長度。詳細地 說，紡紗及輸送管1 〇的長度可以大於紡紗及輸送管1 1的 長度。 第8圖顯示出根據本發明的裝置的第四實施例，其最 -11 - 200916619 好是在需要有特別長的第一紡紗及輸送管10時使用之。 在此情形中，紡紗及輸送管10最好是分割成至少二個部 位10a、10b，具有長度L1及L2’而清潔站16則是設置 於這二個部位1 〇a、1 Ob之間。如同其他的實施例一樣， 具有較短長度K 1的第二紡紗裝置1 4是結合至部位1 Ob上 〇 第9圖及第10圖顯示出清潔站24之結構的另一實施 例，其包含有一撚捻腔室2 4 a，在此例中係堅固地連接至 一可以經由一結合部2 5而緊固地連接至收集導管1 7或機 器零件上的清除管24b上。在出口末端處，撚捻腔室24a 是連接至例如紡紗及輸送管的部位1 〇b上（第8圖），而 在入口末端處，其設有一最好是圓形的開口，其在第1〇 圖中是以由虛線標示的截面加以顯示。紡紗及輸送管的部 位l〇a是設置成與開口 26同軸心，但是根據第9圖是中 止於該開口前方一段特定的軸向距離處。此外，一內徑大 致上相等於部位1 〇a之外徑的管狀延伸件27係可移位地 裝設於部位1 〇 a上。根據第9圖，該延伸件2 7可推壓通 過部位l〇a的前緣末端而插入至開口 26內而在其內達到 作業位置’以供如同其他的實施例一樣，確保清潔站24 在流動上是能與部位1 〇 a、1 0 b的入口或出口末端形成— 實質上封閉的系統。但是’如果需要對清潔站進行清潔、 修理或維護時’該延伸件2 7亦可伸縮式地推回至紡紗及 輸送管的部位l〇a上’而自開口 26內退出，如同第9圖 中雙頭箭號所示。再者’撚捻腔室24a可以設有例如一供 -12- 200916619 壓縮空氣P ίί用的連接管2 0，類似於第2圖。另外，當 也可以將清潔站2 4設置於該二紡紗裝置（例如8及Η 之間，類似於第1圖。此實施例的好處在於清潔站2 4 後面的管部位1 〇 b或是後面的紡紗元件丨2能以堅硬的 式設置。 所述的清潔站1 6、24代表一種可在二紡紗裝置8、 之間’或是在同一紡紗裝置8的二部位1 0 a、1 0 b之間 轉換區域內’收集自然產生的纖維飛屑的有效裝置，以 得纖維、灰麈等等’亦即雜質22，不會進入至環境內， 是被送入至中央吸引裝置或類似者內。此程序可由經連 管20、21 (第2圖及第3圖）供應的壓縮空氣來加以增 〇 第11圖以較大比例顯示出也顯示於第1圖內的編 系統。在紡紗及輸送管1 1內中止於線導孔5處的開口 由撚元件1 2供應的空氣會以一種旋轉而爆發性的方式 逸出去，將留存於纖維材料6內或上的線頭、殼片或類 者加以分離出去’類似於撚捻腔室16a、24a。但是，這 雜質可能會在凸輪總成3上形成堆積物2 8。再者，極短 纖維（線頭）會在針筒1與凸輪總成3間形成另外的堆 物2 9。爲避免此種缺點’本發明的硏發提供一吸引通 3 〇 ’其係設置於凸輪總成3的上方側，並且最好亦連接 該中央吸引裝置，而其吸引開口是位於堆積物2 8最容 形成的處所。以此方式’形成堆積物2 8的雜質可以被 效地吸走。此外’在凸輪總成3及針筒1內亦可設有壓 然 ) 及 方 14 的 使 而 接 進 織 ? 散 似 些 的 積 道 至 易 有 縮 -13- 200916619 空氣通道3 1、3 2，其等係中止於凸輪總成3與針筒丨間的 間隙內，並連接至一壓縮空氣源pii。因此其可以驅散會形 成堆積物29的雜質，而這會使得該等雜質穿過吸引通道 30。在圓編織機運轉期間，吸引及壓縮空氣通道30至32 可以依據需求而間隙性或永久性地使用，且他們可維持此 編織系統沒有不想要的雜質及纖維飛屑。最好能針對此一 目的而設置可自由程式規劃的控制裝置。 第12圖是線導孔5與編織針2間之纖維流的非常通 用的示意外觀圖。快速旋轉的空氣是以一種爆發的方式沿 著切線方向自線導孔5發出。在此同時，纖維材料6會插 入至通過的編織針2內。但是，纖維流的截面會因爲具有 出射角3 5的部份流33及3 4之故，而在該纖維流的二側 逐漸地擴大。可以理解到，出射角3 5愈小，則編織物件 的品質及圓編織機的作業安全就愈高。 在本發明的一較佳實施例中，其可藉由在線導孔5的 下方設置一經由導管3 7加以供應壓縮空氣的吹風通道3 6 、擋板或類似者而達成較小的出射角3 5。吹風通道3 6的 空氣是在出射角3 5的區域內和緩地自其內發出，並且係 將形狀設定爲能使整體出射角3 5縮減。 此外，習用的沉降片3 8，其等係設置於一結合至針筒 (第1圖）上的沉降片環（未顯示）上，亦可如第12圖 中所示設於編織針2 (僅示意地顯示出）之間。再者，箭 號v代表編織針2及沉降片38隨著針筒一起移動的方向 -14- 200916619 第13圖及第14圖顯示出用來在編織系統之區域內監 看編織過程的裝置。一第一感測器3 9緊鄰於線導孔5設 置，並監視纖維材料6是否以正確的方式自其內離開。如 果沒有臨時紗自線導孔5發出，則感測器3 9會發射一錯 誤信號。一第二感測器4 0可偵測編織針2，必須要是舌針 ，的針舌在上升的階段中是否正確地開啓。如果舌針仍維 持關閉情形，則感測器4G會發射錯誤信號。 此外，最好能針對位在於線導孔5與相關之編織系統 的毛圈形成點之間的纖維流設置一光學監視裝置。透過使 用已知的影像及圖形辨識裝置，此監視裝置可掃描一影像 框4 1 (第1 4圖）’在該影像框內可預期會有纖維材料正 確供應時的纖維材料6的截面的預定圖形。不正確的圖形 會造成另一錯誤信號。由於現今在影像處理上的高速度， 此監視可以真時方式爲之。 前述之錯誤信號之一者的產生均會使該發生錯誤的受 影響編織系統的儘快地關閉’或是使該圓編織機停止運轉 ’以使得所造成的任何損害，特別是對於編織之織物，減 至最小。 本發明並不僅限於所揭露的實施例，其等可以許多方 式來加以改良。這首先可應用於以舉列方式說明的圓編織 機，其可由其他的編織機來加以取代，例如亦可使用平編 織機或一段式圓編織機。再者，其他的紡紗裝置，例如特 別是氣流式精紡裝置，亦可用來代替那些配合撚元件作業 者本發明亦可有效地應用於其他必須要供應以已延伸纖 -15- 200916619 維材料的機器。其他的作業站亦可取代編織系統或針縫部 成形站。另外’很明顯的，如果二個以上之紡紗裝置或是 紡紗及輸送管有二個以上的部位’則前述的清潔站可方便 地設置於其間的每一間隙內。再者’針對第1圖至第10 圖所描述的清潔站僅代表較佳的實施例，其等能以許多種 方式來變化之。最後，可以理解的’各種的特點均能以不 同於前面所描述及顯示的組合方式來使用之。 【圖式簡單說明】 第1圖是切開根據本發明之裝置的第一實施例的示意 縱向剖面，該裝置係結合於一用來處理已延伸纖維材料的 編織機上，並且包含有一以封閉流動系統之形式構成的清 潔站。 第2圖及第3圖顯示出該清潔站的二個實施例，每一 者均沿第1圖中線A-A所取的剖面。 第4圖及第5圖是根據第2圖及第3圖之清潔站的剖 面，其具有一撚捻腔室及一由鉸鏈連接至該撚捻腔室上的 清除管。 第6圖至第8圖是根據本發明之裝置的另外三個實施 例對應於第1圖的圖式。 第9圖顯示出一撚捻腔室及與之相關的紡紗及輸送管 間的連接的實施例。 第1 0圖是沿著第9圖中線B - B的剖面。 第11圖顯示出以附加於第1圖至第8圖內的方式存 -16- 200916619 在而可設置於編織機之編織位置區域內的吸引及/或鼓風 裝置。 第1 2圖是編織機之編織系統的外觀圖。 第13圖及第14圖示意地顯示一設置於編織機內而包 含有感測器之用來來監視編織機之作業的裝置。 【主要元件符號說明】 1 :針筒 2 :編織針 3 :凸輪總成 4 :線導 5 :線導孔 6 :纖維材料 7 :牽伸系統 7 a :拉引滾輪 8 :紡紗裝置 9 :紡紗元件 1 0 :紡紗及輸送管 1 0 a :部位 1 0 b :部位 1 1 :紡紗及輸送管 1 2 :紡紗元件 1 4 :紡紗裝置 1 5 :臨時紗 -17- 200916619 1 6 :清潔站 1 6 a :撚捻腔室 16b :清除管 1 6 c :撚捻腔室 1 6 d :開口 1 7 :收集導管 1 7 a :連接管 1 7b :吸引噴嘴 1 8 :撓性結合部 1 9 :鉸鏈 2 0 :連接管 2 1 :連接管 2 2 :雜質 23 :鼓風噴嘴 2 4 :清潔站 24a :撚捻腔室 24b :清除管 2 5 .結合部 26 :開口 2 7 :延伸件 2 8 :堆積物 2 9 :堆積物 30 :吸引通道 3 1 :壓縮空氣通道 -18- 200916619 32 :壓縮空氣通道 3 3 :部份流 3 4 :部份流 3 5 :出射角 3 6 :吹風通道 37 :導管 3 8 :沉降片 3 9 :感測器 40 :感測器 4 1 :影像框 -19Intake and Outtake Flows). This problem can be solved by using the feature structure in item 1 of the patent application. The invention has the advantages that it is disposed between two parts of a spinning and conveying pipe or between two spinning devices, and is formed into a closed system, and can be matched with air blowing and/or Absorbed to actuate the cleaning station's which can achieve effective removal of fragmented fiber flying debris and other impurities. Therefore, the interference to the work process can be greatly reduced, and the accumulation of fiber balls, dust and other impurities in the machine can be avoided. Furthermore, despite the use of a closed flow system, the transport operations required to transport the fibrous material to the station are not affected. Other advantages of the invention are known from the dependent claims. The invention will now be described with respect to the embodiments in conjunction with the drawings. [Embodiment] Fig. 1 schematically shows a device according to the invention, which is supplied to a machine, preferably a knitting machine, in this embodiment, in particular a circular knitting machine, which comprises a knitting needle 2. The syringe 1, a cam assembly 3 connected to the knitting needles 2, and a wire guide 4 provided with the wire guide holes 5. Referring again, a knitting system of the knitting machine is shown in Fig. 1, in which the knitting needle 2 can be lifted by the cam assembly 3 to be adapted to receive the receiving position of the fibrous material 6, which will move Through the wire guide holes 5 -6 - 200916619, the fiber material 6 is produced by each knitting system via respective drafting systems 7, and in the first figure only two pulls in the drafting system are shown The roller 7a is guided and can be introduced into a fiber strip, a wing strip or the like in a manner not shown. In this embodiment, the fiber strip from the drafting system 7 and drawn to the desired degree of slenderness is introduced into a spinning device 8, which comprises a spinning element 9, here In the example, a crucible element driven by compressed air crucibles, and a spinning and conveying tube connected thereto. A second spinning and conveying pipe 1 is attached to the spinning and conveying pipe 10, and the outlet end thereof is stopped in the wire guide hole 5. It is particularly advantageous to connect the inlet end of the second spinning and conveying pipe 11 to a second spinning element 1 2 ' such that the spinning element 9 and the spinning and conveying pipe 1 can constitute the spinning device 8, The spinning element 12 and the spinning and conveying pipe 1 1 constitute a second spinning device 14 which is arranged behind the spinning device 8 in the conveying direction of the fiber material 6. The spinning device 8 is used to convert the fiber bundle provided by the drafting system 7 into a temporary yarn 15 having an actual crotch portion which can be maintained from the second spinning device 14 to the wire guide 4 . The wire guide 4 is located behind the fiber conveying direction, and the crotch portions are substantially loosened due to the false twisting effect, so that the fiber material 6 introduced into the knitting needle 2 is substantially fiber-free. material. A circular knitting machine of the type described above is known, for example, from the documents PCT WO 2004/079068 and DE 10 2006 006 502 ,1, which are hereby incorporated by reference in their entireties in the entire content in the the the the the According to the present invention, a cleaning station 16 is disposed between the exit end of the spinning and conveying pipe 1 及 and the inlet end of the spinning element 12, and is connected to a collecting duct 17 for cleaning from the fiber stream. Remove impurities. As used herein, "cleaning" is understood to mean that all impurities carried in the fiber stream, such as fiber balls, dust, staple fibers, thread ends, shell sheets, etc., are removed as much as possible in station 16. It does not damage the fiber flow or the temporary yarn 1 5 itself or hinder its movement into the wire guide 4. The cleaning station 16 is connected to the outlet end of the spinning and conveying pipe 1 and the inlet end of the spinning element 12 such that the station can cooperate with it to form a substantially closed flow system, i.e. from the fiber stream The separated impurities are directly introduced into the collecting duct 17 without reaching the external environment. According to Figs. 2 to 5, the cleaning station 16 preferably includes a crucible chamber 16a surrounded by a casing, and a cleaning tube 16b which can also be formed into a conical shape as shown in Fig. 4. In order to be able to maintain and repair the cleaning station 16, it is connected to the collection by, for example, a flexible joint 18 (Fig. 1) or a pivotal connection (Figs. 4 and 5). On the duct 17, it is also possible to make the hinge 19 according to Figs. 4 and 5 a hinge 19 disposed between the weir chamber 16a and the purge tube 16b, which is shown in Fig. 4 The position is closed, and in Figure 5 it is the open position. This configuration can also be arranged to pivot or slide the cleaning station 16 or the chamber 16a together with the rear spinning device 1 4, if desired. The crucible chamber 16a is formed substantially as a closed chamber that is connected to the knotting and conveying pipe 10 and the spinning member 12 in flow. The chamber is used with 200916619 to release the fibers, impurities and the like carried by the air from the fibrous material entering the inside of the conveying pipe 1 before the fibrous material or the temporary yarn 15 enters the next spinning device 14. Come out and introduce them into the collection duct 17 via the purge tube 16b. According to the second and third figures, the weir chamber 16a is preferably additionally provided with a connecting pipe 20 or 2 1, for example, vertically upward or obliquely downward, the connecting pipe is arranged to be spun with And the conveying pipe 10 is tangent. Compressed air ρϋ is introduced into the 捻捻 chamber i6a via the connecting pipes 20, 21 to maintain and improve the separation process. The compressed air introduced through the connecting pipes 20, 21 also drives the fibrous material entering the crucible chamber 16a in the direction of rotation, as indicated by the arrows in Figures 2 to 5. Loose fibers and the like are simultaneously driven into the purge tube 16b. Thus, as well as the achievement of the marked impurities 2 2 , such as fiber flying chips, dust, etc., the fiber stream is naturally and efficiently separated, as shown schematically in Figures 2 to 4 . The impurities 2 2 separated from the fiber stream can be removed via the purge tube 16 b and the collection conduit 17 ', and the collection conduit is bonded to a central suction device such as a circular braiding machine to cause a negative pressure pu It can be filled and selectively filled in the purge tube 16b. Alternatively, the collection conduit 17 can be coupled to a source of compressed air for creating an overpressure ρ within it that can carry the impurities 22 along them and direct them to a central collection point. Since the pressure supplied to the helium chamber 16a and the purge tube 16b is relatively low, the additional energy requirements required by the cleaning station 16 are also low. -9- 200916619 A second embodiment according to the present invention is shown in Fig. 6, wherein the same parts are denoted by the same reference numerals as in Figs. 1 to 5. Unlike the first to fifth figures, the rear side of the collecting duct 17 extends out of a connecting tube 17a. This system terminates in a suction nozzle 17b, and its inlet end is disposed in close proximity to the drafting system 7, in particular the upper and/or lower rollers in the pair of pulling rollers 7a, so that the fibers produced by the space fly The chips can also be delivered to the collection conduit 17. The suction nozzle Hb can be easily combined with a blast nozzle 23 which is driven by the overpressure ρ, and by which the cleaning effect in the region of the pair of pulling rollers 7a can be further improved. The figure further shows that the second spinning and conveying pipe i i in this example has a smaller diameter than the first spinning and conveying pipe 1 。. Therefore, the volume to be drawn in the spinning tube 10 is increased relative to the volume to be drawn in the spinning tube 11 'and thus enhances the effect of cleaning and impurity removal. Moreover, after the stable operation of the device, that is, after the online connection, the overpressure pti in the spinning nozzle 9 can be reduced or set to zero 値. In this case, the cleaning function is generally only based on the collecting conduit. Negative pressure within 1 7 can be used to save energy. Further, Fig. 6 shows that the cleaning station 16 includes a chamber i6c' which differs from the first embodiment in that it includes a downward projection, preferably a conical joint member, which is provided with a small Clean or attract the opening 16d. As in Figure 1, the joint allows for the ingress of impurities from the fiber stream, and the cleaning of the opening 16d allows the air from the collection conduit 17 to be drawn in, as indicated by the arrows. Therefore, the impurities will be sucked up and prevented from falling -10 - 200916619 through the opening 1 6d. Overall, the apparatus according to Fig. 6 constitutes a substantially closed flow system. Alternatively, a compressed air connection can be incorporated at the cleaning opening 16d to create a flow relationship similar to that of Figures 2 and 3. A third embodiment of the apparatus according to the invention is shown in Figure 7, and the spinning and conveying pipe 10 also has a larger diameter than the spinning and conveying pipe 11. The negative pressure in the cleaning station is high (pu>>), with the magnitude of the negative pressures used in Frame Spinning and Compact Spinning. The spinning element 9 is located at a distance "at a minimum distance from the pulling roller 7a" and protrudes into the space therein. This results in a strong suction flow in the spinning and conveying pipe 10 which keeps the pulling roller 7a clean. The air pressure in the spinning member 9 ensures the necessary rotation of the spinning and conveying pipe 1 so that the fiber flying chips can be separated from the crucible chamber 16a. This device has fewer components. In this way it is advantageously possible to make the negative pressure at the start-up phase of this machine low. The pressure in the spinning element 12 can be conveniently adjusted so that the spinning tension is high enough to rotate the temporary yarn 15 without touching the wall of the spinning and conveying tube. With this configuration, the spinning device 8 can have a high overall length L' without adversely affecting the spinning process, so the yarn-preventing device 8 can have a length L > K, where K is the spinning device The length of 1 4 . In detail, the length of the spinning and conveying pipe 1 可以 can be larger than the length of the spinning and conveying pipe 1 1 . Fig. 8 shows a fourth embodiment of the apparatus according to the invention, the most -11 - 200916619 being used when a particularly long first spinning and conveying pipe 10 is required. In this case, the spinning and conveying pipe 10 is preferably divided into at least two portions 10a, 10b having lengths L1 and L2' and the cleaning station 16 is disposed between the two portions 1 〇a, 1 Ob . As with the other embodiments, the second spinning device 14 having the shorter length K 1 is another embodiment in which the structure of the cleaning station 24 is shown in conjunction with the embossing of the portion 1 Ob and the ninth and tenth drawings. A chamber 24a is included, which in this example is rigidly coupled to a purge tube 24b that can be securely coupled to the collection conduit 17 or machine part via a joint 25. At the end of the outlet, the crucible chamber 24a is connected to a portion 1 〇b such as a spinning and conveying pipe (Fig. 8), and at the end of the inlet, it is provided with a preferably circular opening, In the first figure, it is shown by a section indicated by a broken line. The portion of the spinning and conveying pipe l〇a is disposed concentrically with the opening 26, but is stopped at a specific axial distance in front of the opening according to Fig. 9. Further, a tubular extension member 27 having an inner diameter substantially equal to the outer diameter of the portion 1 〇a is detachably mounted on the portion 1 〇 a. According to Fig. 9, the extension member 27 can be pushed into the opening 26 through the leading end of the portion l〇a to reach the working position ' therein for the same as in other embodiments, ensuring that the cleaning station 24 is The flow is formed into a substantially closed system with the inlet or outlet end of the part 1 〇a, 10 b. However, 'if the cleaning station needs to be cleaned, repaired or maintained, the extension member 27 can also be telescopically pushed back to the spinning and conveying pipe portion l〇a' and exits from the opening 26, as in the ninth. The double-headed arrows in the figure are shown. Further, the 捻捻 chamber 24a may be provided with, for example, a connecting pipe 20 for -12-200916619 compressed air P ί, similar to Fig. 2. In addition, it is also possible to arrange the cleaning station 24 between the two spinning devices (for example between 8 and ,, similar to Fig. 1. The advantage of this embodiment is that the tube portion 1 〇b behind the cleaning station 24 or The latter spinning element 丨 2 can be arranged in a rigid manner. The cleaning station 16 , 24 represents a type that can be between the two spinning devices 8 , or at two locations of the same spinning device 8 10 a , an effective device for collecting naturally-generated fiber flying chips in the transition area between 10 b, to obtain fibers, ash, etc., that is, the impurities 22, which do not enter the environment, are sent to the central suction device Or the like. This program can be enhanced by the compressed air supplied through the pipes 20, 21 (Fig. 2 and Fig. 3). Fig. 11 shows the editing system also shown in Fig. 1 on a large scale. The air supplied to the opening at the wire guide hole 1 in the spinning and conveying pipe 1 by the weir element 12 will escape in a rotatable and explosive manner, leaving the wire in or on the fiber material 6. The head, shell or class is separated out 'similar to the chambers 16a, 24a. However, this impurity Deposits 28 may be formed on the cam assembly 3. Further, very short fibers (thread ends) may form additional stacks 29 between the syringe 1 and the cam assembly 3. To avoid this drawback, The burst of the invention provides a suction passage 3' which is disposed on the upper side of the cam assembly 3, and is preferably also connected to the central suction means, and its suction opening is the location where the deposit 28 is most formed. In this way, the impurities forming the deposits 28 can be effectively sucked away. In addition, 'there is also a pressure in the cam assembly 3 and the syringe 1) and the square 14 is connected to the weave. The accumulation channel is easy to shrink-13-200916619 The air passages 3 1 and 3 2 are suspended in the gap between the cam assembly 3 and the syringe bore and connected to a compressed air source pii. It is therefore possible to dissipate the impurities which will form the deposit 29 which will cause the impurities to pass through the suction channel 30. During operation of the circular knitting machine, the suction and compression air passages 30 to 32 can be used intermittently or permanently depending on the demand, and they can maintain the braided system with no unwanted impurities and fiber flying debris. It is preferable to provide a freely programmable control device for this purpose. Fig. 12 is a schematic view showing the very general appearance of the fiber flow between the wire guide hole 5 and the knitting needle 2. The rapidly rotating air is emitted from the wire guide 5 in a tangential direction in an explosive manner. At the same time, the fibrous material 6 is inserted into the passing knitting needle 2. However, the cross-section of the fiber stream will gradually enlarge on both sides of the fiber stream due to the partial flows 33 and 34 having an exit angle 35. It can be understood that the smaller the exit angle 35, the higher the quality of the knitted object and the safety of the circular knitting machine. In a preferred embodiment of the present invention, a smaller exit angle 3 can be achieved by providing a blowing passage 3 6 , a baffle or the like for supplying compressed air via the conduit 37 under the wire guide hole 5 . 5. The air of the blowing passage 36 is gently and internally emitted from the area of the exit angle 35, and is shaped to reduce the overall exit angle 35. In addition, the conventional sinker 3 8 is disposed on a sinker ring (not shown) coupled to the syringe (Fig. 1), and may be disposed on the knitting needle 2 as shown in Fig. 12 ( Only shown schematically between). Furthermore, the arrow v represents the direction in which the knitting needle 2 and the sinker 38 move with the syringe. -14- 200916619 Figures 13 and 14 show the means for monitoring the weaving process in the area of the weaving system. A first sensor 39 is placed in close proximity to the wire guide 5 and monitors whether the fibrous material 6 has exited therein in the correct manner. If no temporary yarn is emitted from the wire guide 5, the sensor 39 emits an error signal. A second sensor 40 detects the knitting needle 2, which must be the tongue, and the tongue is correctly opened during the ascending phase. If the latch still remains closed, the sensor 4G will emit an error signal. Moreover, it is preferred to provide an optical monitoring device for the fiber flow between the wire guide holes 5 and the loop forming points of the associated weaving system. By using a known image and pattern recognition device, the monitoring device can scan an image frame 4 1 (Fig. 14). A predetermined section of the fiber material 6 in which the fiber material is expected to be properly supplied in the image frame. Graphics. An incorrect graphic will cause another error signal. Due to the high speed of image processing today, this monitoring can be done in real time. The occurrence of one of the aforementioned error signals causes the erroneous affected braiding system to close as quickly as possible 'or stop the circular knitting machine' so as to cause any damage, especially for woven fabrics, Minimized to a minimum. The invention is not limited to the disclosed embodiments, and the like may be modified in many ways. This can first be applied to a circular knitting machine illustrated by way of example, which can be replaced by other knitting machines, for example, a flat weaving machine or a one-stage circular knitting machine. Furthermore, other spinning devices, such as, in particular, air-flow spinning devices, can also be used in place of those that cooperate with the 捻 element. The invention can also be effectively applied to other materials that have to be supplied with the stretched fiber -15-200916619 dimension. Machine. Other work stations can also replace the weaving system or the stitch forming station. Further, it is obvious that if two or more spinning devices or spinning and conveying pipes have more than two portions, the aforementioned cleaning station can be conveniently disposed in each gap therebetween. Further, the cleaning stations described with respect to Figures 1 through 10 represent only preferred embodiments, and the like can be varied in a number of ways. Finally, it will be understood that the various features can be used in a combination that is different from those previously described and shown.
