201229342 六、發明說明： 【發明所屬之技術領域】 本發明係關於一種對紗線噴射流體而產生交絡或迴圈 (1 ο ο p)等，以對紗線賦予蓬鬆性的紗線處理裝置。 【先前技術】 習知以來，已有一種紗線處理裝置，其係對由合成樹 Q 脂等之長絲（filament)所構成的紗線噴射流體，且藉由在 長絲產生交絡或迴圏等，而對紗線賦予蓬鬆性。 在專利文獻1、2，係分別揭示一種具備紗線通路、 噴嘴及球狀碰撞體的紗線處理裝置，該紗線通路係具有紗 線導入部及紗線排出部，該噴嘴係具備有對該紗線通路內 噴射壓縮空氣的空氣噴射孔；該球狀碰撞體係配置成與該 噴嘴之紗線排出部相對向。 在前述專利文獻1、2的紗線處理裝置中，從紗線導 Q 入部導入的紗線，係通過可供空氣噴射的紗線通路內並從 紗線排出部排出。在此，從紗線排出部出來的空氣係碰撞 到球狀碰撞體並沿著其表面而流動，使紗線乘著該空氣之 流動，通過紗線排出部和碰撞體之間的間隙而排出。此時 ，會因紗線排出部內產生的空氣流動而在長絲產生迴圏或 交絡等，可對紗線賦予蓬鬆性。 (專利文獻1)日本特表2000-514509號公報（尤其是第 5圖、第6圖及第8圖） (專利文獻2)日本特開2000-303280號公報 201229342 【發明內容】 (發明所欲解決之問題） 但是，在使用球狀碰撞體的習知紗線處理裝置中’有 時蓬鬆加工也會變得不充分，且有要做更進一步改善的餘 地。因此，本案發明人係爲了查明上述原因而精心進行檢 討的結果，發現了以下見解：碰撞體之形狀對於紗線處理 裝置之加工性能有著極大影響，且藉由對碰撞體之形狀下 工夫可提高加工性能。 本發明之目的係在於提供一種紗線之加工性能高的紗 線處理裝置。 (解決問題之手段） 第1發明的紗線處理裝置，其特徵爲，具備：噴嘴， 其係具有紗線通路及流體噴射孔，該紗線通路係具備紗線 導入部及紗線排出部，該流體噴射孔係朝向前述紗線通路 噴射流體；以及碰撞體，其係具有「與前述紗線排出部之 形成有排出口的前端面保持間隙地相對向」的面，且前述 碰撞體之「與前述紗線排出部之前述前端面相對向」的面 之中’與前述排出口的對向部分，係形成爲凹狀。 依據本發明，由於與噴嘴之排出口相對向的碰撞體之 對向部分，係形成凹部，所以在噴嘴的紗線排出部和碰撞 體之間可確保較大的空間，且容易在該空間內擾動流體之 流動。因而，容易在「藉由前述空間內劇烈的流體流動而 從紗線排出部排出」的長絲產生迴圈或交絡，且提高紗線 -6 - 201229342 的加工性能。又’所謂提高紗線的加工性能，亦指即便以 比習知還快的紗線速度進行加工仍可實現同等級以上的加 工品質，亦可謂提高生產性。 第2發明的紗線處理裝置，在前述第1發明中，前述 碰撞體之凹狀的前述對向部分之內面，係由曲面所形成。 當碰撞體之凹部的對向部分之內面爲曲面時，由於從 紗線排出部與紗線一起排出的流體，會在對向部分之內側 0 空間沿著其內面而流動，所以流體不容易局部性地滯留， 且更容易在長絲產生迴圈或交絡，可提高紗線的加工性能 〇 第3發明的紗線處理裝置，在前述第1或第2發明中 ，前述碰撞體之前述對向部分，係在其中央部形成最凹陷 的形狀。 當碰撞體之對向部分，在其中央部成爲最凹陷的形狀 時，從紗線排出部排出而來的紗線，就會集中碰撞於凹狀 Q 的對向部分之最內深部。如此，藉由紗線集中碰撞到碰撞 體的一處，之後的紗線加工（迴圈形成或交絡）就會穩定’ 且提高紗線的加工性能。 第4發明的紗線處理裝置，在前述第1發明中，前述 碰撞體之前述對向部分的剖面形狀’爲圓弧狀或橢圓弧狀 〇 在碰撞體之對向部分的剖面形狀爲圓弧狀或橢圓弧狀 的情況下，對向部分之內面係成爲曲面’而且在對向部分 之中央部係成爲最凹陷的形狀。因而’如在前述第2及第 201229342 3發明所說明般’由於流體不容易局部性地 生迴圈或父絡’並且可穩定地進行迴圈之形 以可更進一步提高紗線的加工性能。 第5發明的紗線處理裝置，在前述第1 個發明中，在前述碰撞體之前述對向部分， 平坦部’該平坦部係與包含前述排出口的前 之前端面呈平行，且包圍前述凹部。 當碰撞體之與排出口的對向部分之全體 其端部就會成爲尖銳的形狀。在該情況下， 體發生端部形狀之不均等，或是在端部產生 如此會對紗線的加工帶來極大的影響。具體 線的張力不均等或產生起絨等的原因。然而 ，由於是在碰撞體之對向部分，形成有凹部 該凹部的平坦部，所以對向部分之端部形狀 ，又由於也不容易產生缺陷，所以紗線的加 第6發明的紗線處理裝置，在前述第1 個發明中，具有保持前述噴嘴的噴嘴座，且 安裝於前述噴嘴座，不僅如此，在前述噴嘴 導件，該紗線導件#導引「通過前述噴嘴之 前述碰撞體之間而出來」的紗線。 爲了使從噴嘴之紗線排出部排出的紗線 最好是在比噴嘴更下游側設置紗線導件。但 的張力會隨著紗線導件之相對於噴嘴的位置 所以在與紗線處理裝置另外設置紗線導件時 滞留且容易產 成或交絡，所 至第4中任一 形成有凹部及 述紗線排出部 成爲凹狀時， 有時會在碰撞 細微的缺陷， 而言，造成紗 ，在本發明中 以及用以包圍 的不均等較小 工穩定。 至第5中任一 前述碰撞體係 座設置有紗線 紗線排出部和 之行走穩定， 是，由於紗線 而有所改變， ，爲了適當地 -8- 201229342 設定紗線的張力，就有需要：在設置紗線處理裝置之後， 更進一步調整紗線導件之相對於紗線處理裝置（噴嘴）的位 置之麻煩作業。在本發明中，由於是在設置有噴嘴及碰撞 體的噴嘴座’更進一步設置有紗線導件，並使噴嘴或碰撞 體和紗線導件成爲一體，所以只要將紗線處理裝置設置在 預定位置就可自動地決定紗線導件之位置，且沒有調整紗 線導件之位置的必要。 (發明效果） 依據本發明，由於與噴嘴之排出口相對向的碰撞體之 對向部分，係形成凹狀，所以在噴嘴的紗線排出部和碰撞 體之間可確保較大的空間，且容易在該空間內擾動流體之 流動。因而，容易在藉由前述空間內劇烈的流體流動而從 紗線排出部排出的長絲產生迴圏或交絡，且提高紗線的加 工性能。又，所謂提高紗線的加工性能，亦指即便以比習 〇 知還快的紗線速度進行加工仍可實現同等級以上的加工品 質，亦可謂提高生產性。 【實施方式】 其次，就本發明的實施形態加以說明。第1圖係本實 施形態的紗線處理裝置之前視圖；第2圖係紗線處理裝置 之左側視圖；第3圖係以剖面顯示第1圖的紗線處理裝置 之一部分的示意圖。又，第4圖（a)係第3圖所示的噴嘴 及碰撞體之放大圖；第4圖（b)爲第4圖（a)的碰撞體之右 201229342 側視圖。另外’以下’係將第1圖、第3圖中的上下左右 之方向定義爲上下左右而加以說明。如第1圖至第3圖所 不，紗線處理裝置1’係具備：噴嘴2;及保持該噴嘴2 的噴嘴座3;以及設置於噴嘴座3的碰撞體4。 首先，就噴嘴2加以說明。如第3圖、第4圖（&)所 示’噴嘴2係藉由金屬或陶瓷等的硬質材料而形成筒狀， 且在該噴嘴2之一端部設置有朝向徑向膨出的凸緣部2a 。又，在噴嘴2之內部係形成有延伸於噴嘴2之筒軸方向 的紗線通路1 0。紗線通路10，係具有：形成於噴嘴2之 凸緣部2a側（右側部分）的紗線導入部1 1 ;及形成於與噴 嘴2之凸緣部2a爲相反側（左側部分）的紗線排出部1 2 ; 以及連繫紗線導入部1 1和紗線排出部1 2的空氣導入部 13° 在位於噴嘴2之右端部的凸緣部2a之端面係開設有 可供紗線3 1導入的導入口 1 1 a，且紗線導入部11，係形 成越從前述導入口 1 1 a朝向前端側（圖中左側）則內徑就越 縮小的尖頭狀。另一方面，在與凸緣部2a爲相反側的噴 嘴2之左端面係開設有可供被導入於紗線通路1 〇內的紗 線3 1排出之排出口 i 2 a，且紗線排出部1 2，係形成越朝 向排出口 1 2 a則內徑就越擴大的尾寬形狀。作爲尖頭的紗 線導入部1 1或尾寬的紗線排出部1 2之形狀，例如可採用 推拔狀、或位於開口端的擴展程度（曲率）比推拔狀還大的 喇叭狀等。作爲一例，在本實施形態中，紗線導入部u 爲喇叭狀，紗線排出部1 2爲推拔狀。 -10- 201229342 在噴嘴2之筒軸方向中央部，係設置有朝向紗線通路 1 0之空氣導入部1 3開口的空氣噴射孔1 4(流體噴射孔）。 另外，在第4圖（a)中雖然只有顯示一個空氣噴射孔14, 但是實際上可將複數個（例如三個）空氣噴射孔14分別配 置在噴嘴2之圓周方向等間隔位置。又，空氣噴射孔14 ，係相對於噴嘴2之半徑方向（與紗線通路10正交的方向 )，朝向紗線通路1 〇之前端側（左側）傾斜而延伸，且可在 0 朝向紗線通路1 〇噴射空氣時產生朝向左側之較強的空氣 流。 其次，就噴嘴座3加以說明。如第1圖至第3圖所示 ，噴嘴座3，係形成上下稍微長的長方體形狀。在該噴嘴 座3之上側部分，形成有水平地貫通噴嘴座3的安裝孔 20。另外，雖然在該安裝孔20插入有上述的噴嘴2，但 是安裝孔20之直徑係比噴嘴2的凸緣部2a之外徑還小。 因此’可從右側之開口將噴嘴2之左端部插入安裝在安裝 Q 孔20 ’另—方面，設置在噴嘴2之右端部的凸緣部2a係 未插入於安裝孔20而是抵接到噴嘴座3之右側面，藉此 ’噴嘴2可相對於噴嘴座3來定位。又，如第1圖所示， 在噴嘴座3，安裝有防止被插入於安裝孔2 0的噴嘴2朝 向右側飛出的限制構件22。 在噴嘴座3之內部形成有朝向上下延伸的空氣供給孔 2 1 ’且該空氣供給孔2 1連接於未圖示的空氣供給源。又 ’在噴嘴2安裝於噴嘴座3之安裝孔2 〇時，形成於噴嘴 2的空氣噴嘴孔14會與空氣供給孔21連通，而由空氣供 -11 - 201229342 給孔2 1所供給的空氣，可從空氣噴射孔1 4朝向紗線通路 1 0噴射。 其次’就碰撞體4加以說明。如第3圖、第4圖所示 ’碰撞體4係具有大致呈圓板狀外形之構件，且由金屬或 陶瓷等的硬質材料所形成。該碰撞體4，係與安裝於噴嘴 座3的噴嘴2之左端面（紗線排出部1 2之形成有排出口 1 2 a的前端面）’保持些微的間隙而相對向。 碰撞體4之與噴嘴2之左端面相對向的右面之中，與 排出口 12a相對向的中央部係形成爲凹部4a。該凹部4a 之內面’其位於包含噴嘴2之中心軸的平面之剖面，則構 成爲圓弧狀的曲面。又，凹部4a，係由平坦部4b所包圍 ’該平坦部4 b係具有與紗線排出部丨2之前端面呈平行的 平坦面。 另外，雖然將碰撞體4保持於與噴嘴2之排出口 1 2 a 相對向的位置之構成並未被特別限定，但是在本實施形態 中係採用如以下的構成作爲一例。首先，如第丨圖所示， 在噴嘴座3之下部左側面藉由螺栓等而固定安裝基底構件 2 3 ’且在該安裝基底構件2 3以能夠在鉛垂面內轉動自如 的方式連結有塊狀的保持具24之下部。又，在保持具24 固定有連結棒2 5之一端，且在連結棒2 5之另一端係固定 有碰撞體4。在該構成中’如第3圖之二點鏈線所示，當 保持具24相對於安裝基底構件23而轉動時，碰撞體4也 會一體地轉動’且碰撞體4能夠遍及以下二個位置而移動 :與噴嘴座之排出口 1 2 a相對向的位置（實線所示的位置） -12- 201229342 、以及遠離排出口 1 2a的退避位置（二點鏈線所示的位置） 。然後，藉由使碰撞體4移動至退避位置，就可輕易地進 行往噴嘴2內的穿紗作業。 另外，爲了要穩定從噴嘴2之紗線排出部12排出後 的紗線3 1之行走，最好是在比噴嘴2更下游側設置紗線 導件。但是，噴嘴下游側的紗線之張力會隨著紗線導件相 對於噴嘴2的位置而改變。因此，在獨立於紗線處理裝置 0 1之外另行設置紗線導件時，爲了要適當地設定紗線之張 力，就有需要：在設置紗線處理裝置之後，更進一步調整 紗線導件之相對於紗線處理裝置1 (噴嘴2)的位置之麻煩 作業。 因此，如第1圖、第2圖所示，在本實施形態中，係 在固定於噴嘴座3的安裝基底構件23，透過安裝構件27 而設置有對於從噴嘴2排出而來的紗線進行導引的紗線導 件26。亦即，在設置有噴嘴2及碰撞體4的噴嘴座3，更 〇 進一步設置有紗線導件26，並使噴嘴2或碰撞體4和紗 線導件2 6構成爲一體。然後，從第1圖之右側通至噴嘴 2內而從紗線排出部1 2排出的紗線，可經由位處於第1 圖之前方側（第2圖中爲右側）的紗線導件而朝向上方導引 。如上述般，藉由紗線導件26與噴嘴座3構成爲一體， 則只要將紗線處理裝置1設置於預定位置，紗線導件26 之位置也就能夠自動地決定，且沒有必要調整紗線導件 26之相對於噴嘴2的位置。 其次，就本實施形態的紗線處理裝置i之進行蓬鬆加 -13- 201229342 工時的作用加以說明。首先，如第1圖至第3圖所示，可 從設置於噴嘴2的紗線導入部1 1的導入口 1 1 a，導入由 合成樹脂等之長絲所構成的紗線31，並朝空氣導入部13 導引。又，由圖面中未顯示的空氣供給源所供給的空氣， 是由空氣噴射孔14噴射至空氣導入部13。 噴射至空氣導入部13的空氣係從紗線排出部12排出 ’進而碰撞到與排出口 12a相對向配置的碰撞體4，且乘 著此時的空氣流動’紗線3 1會從碰撞體4和紗線排出部 1 2之間的間隙排出。此時，紗線3丨之構成長絲可藉由紗 線排出部1 2內之劇烈的空氣流動而搓開，進而藉由各個 長絲的劇烈運動而產生迴圈或交絡等，藉此可對紗線3 1 提供蓬鬆性。 在此，如前述般，在本實施形態的紗線處理裝置1中 ，係在碰撞體4之與排出口 12a相對向的面形成有凹部 4a。因此，在噴嘴2的紗線排出部12和碰撞體4之間可 確保較大的空間，且在該空間內容易擾動空氣之流動。因 而，由於容易在藉由劇烈的空氣流動而從紗線排出部1 2 排出的長絲產生迴圈或交絡，所以可提高紗線的加工性能 。又，所謂提高紗線處理裝置1的加工性能，亦指即便以 比習知還快的紗線速度進行加工，仍可獲得與習知同等的 加工品質，並提高生產性，又可減少加工某單位長度之紗 線所需的空氣消耗量。 又，在本實施形態中，碰撞體4之凹部4 a係由剖面 圓弧狀的連續曲面所形成。當凹部4 a由曲面所形成時， -14- 201229342 由於從紗線排出部1 2與紗線一起排出的空氣， 部4a內之空間沿者其內面而流動，所以空氣不 性滯留’而更容易在長絲產生迴圏或交絡。又， 狀的凹部4a ’係在其中央部（可供噴嘴2之中心 位置）構成最凹陷的形狀，且從紗線排出部1 2排 紗線，係集中碰撞於凹部4a之最內深部。如此 由紗線集中碰撞到碰撞體4之一處，就可穩定地 的紗線加工（迴圈形成或是交絡），且提高紗線的 又，在本實施形態中，係在碰撞體4之與排Η 的對向部分’設置有凹部4a和用以包圍該凹部的 4 b。在該情況下’與碰撞體4之對向部分的全體形 ’且與端部（外周部）爲尖銳的情況（後面所列舉的 態之第5圖（e))相較’由於碰撞體4的前述對向部 部（外周部）形狀的不均等會變小，又缺陷也不容易 0 所以可穩定進行紗線的加工。另外，雖然當將碰撞 外徑設爲D，將凹部4a之直徑設爲d，將平坦部 度設爲t時’會變成爲D = d + 2t，但是該平坦部4b t’最好是可決定在5(mm)之範圍內。 另外’本發明並非被限定於前述的實施形態， 下述例示般’只要在不脫離本發明之趣旨的範圍內 加適當變更。 1]碰撞體4之「與噴嘴2之排出口 12a的對向 之凹形狀，並非被限於前述實施形態的剖面圓弧狀 ί會在凹 =易局部 I面圓弧 !通過的 丨而來的 •來，藉 ;行之後 1工性能 i □ 12a I平坦部 :成凹狀 變更形 ;分之端 發生， 體4之 4b之寬 之寬度 而可如 丨仍可施 丨部分」 :。例如 -15- 201229342 ，如第5圖所示，亦可採用（a)橢圓弧狀、（b)鍋底狀、（c) 梯形、（d)圓錐狀等，作爲凹部4a之剖面形狀。 另外’弟5圖（a)至（d)之中’（a)之橢圓弧狀的凹部4a ，係與前述實施形態之圓弧狀的凹部（參照第4圖）同樣， 由於其內面由曲面所形成，所以空氣會沿著其內面流動而 不谷易局部性滯留，且容易在紗線產生迴圈或交絡。又， 在（a)之橢圓弧狀和（d)之圓錐狀中，由於在其中央部最爲 凹陷，所以紗線會集中碰撞到碰撞體之最內深部，藉此可 穩定地進行之後的紗線加工。 又’如前述實施形態的第4圖般，凹部4a僅設置於 碰撞體4的排出口 1 2a側之面的一部分，且凹部4a之周 圍不一定需要由平坦部4b所包圍，又如第5圖（e)般，碰 撞體4的排出口 1 2a側之面全體亦可構成爲凹部4a。 2]噴嘴2，並不侷限於如前述實施形態之第4圖（a)的 形狀。例如’如第6圖（a)所示，紗線導入部u亦可爲推 拔狀，而紗線排出部12亦可爲喇队狀。或者如第6圖（b) 所示’紗線導入部1 1亦可爲直徑不變化的直條狀。 3 ]雖然在前述實施形態中碰撞體4構成能夠相對於噴 嘴座3移動（轉動）’但是碰撞體4亦可被固定於噴嘴座3 [實施例] 其次’就本發明的具體實施例，與比較例相較而加以 說明。 -16- 201229342 (1)噴嘴及碰撞體的規格 將在實施例及比較例中使用的4種類之噴嘴規格顯示 於表1，而將6種類之噴嘴規格顯示於表2。又，將此等 的噴嘴及碰撞體之組合顯示於第7圖。 [表1] 噴嘴 No. 噴嘴形狀 排出口徑 K(mm) 空氣噴射孔徑 (mm) 紗線導入部 紗線排出部 No.l 喇叭狀 推拔狀 6 0.5 No.2 喇叭狀 推拔狀 6 0.6 No.3 推拔狀 喇叭狀 13 0.6 No.4 推拔狀 喇叭狀 13 0.75 [表2] 碰撞體名稱 形狀 詳細 Cup(l 1mm) 凹狀 凹部直徑(d)=llmm、凹部深度(h)=0.8mm Cup(20mm) 凹狀 凹部直徑(d)=20mm、凹部深度(h)=3.0mm Cup(24mm) 凹狀 凹部直徑(d)=24mm、凹部深度(h)=4.5mm Ball(6mm) 球狀 直徑6mm Ball(13mm) 球狀 直徑13mm Plate 平板狀 — 表1之No. 1噴嘴和No.2噴嘴，爲第7圖左側之（1) 所示的噴嘴。又，表1之No.3噴嘴和No.4噴嘴，爲第7 圖左側之（2)所示的噴嘴。但是，如表1所示，在No. 1噴 嘴和No.2噴嘴中，空氣噴射孔之直徑有所不同，且適用 的紗線之粗度範圍有若干偏差（No . 1噴嘴爲細的紗線用， No.2噴嘴爲粗的紗線用）。又，就No.3噴嘴和No.4噴嘴 -17- 201229342 而言也是同樣。 又，如表2所示’就碰撞體而言，係使用噴嘴之與排 出口的對向部分形成凹狀之作爲適用本發明的實施例之3 種類的碰撞體（Cup)、作爲比較例之2種類的球狀碰撞體 (Ball)以及1種類之平板狀的碰撞體（piate)之合計6種類 。在第7圖中’（a)、（e)爲13mm的球狀碰撞體，（b)、（f) 爲6mm的球狀碰撞體，（c)、（g)爲平板狀碰撞體，（d)、 (h)爲本發明的凹狀碰撞體。又，6種類的碰撞體全部爲陶 瓷製。 (2)因碰撞體形狀之差異而引起的加工性能之比較檢討 就紗線處理裝置之加工性能因碰撞體形狀之差異而有 何改變加以檢討。亦即，組合表1之噴嘴和表2之碰撞體 ，且改變紗線之材質、及紗線之粗度並分別進行實驗，再 就各個實驗例測量了噴嘴下游側（排出側）的紗線張力。 另外，在此，藉由將芯紗（core yarn)和花紋紗（effect yarn)以不同的供給速度分別供給至噴嘴並進行加工，而 執行芯紗和花紋紗加工。又，使噴嘴下游側之紗線速度（ 排出側紗線速度）以4階段進行變化’並且測量了「當將 有關芯紗和花紋紗之各個的過剩進給量（往噴嘴的供給紗 線量（供給側紗線速度）之相對於排出紗線量（排出側紗線 速度）的過剩率）設爲固定時」的排出側之紗線張力（單位 :gr)。將聚酯絲（PET)，且紗線粗度分別爲150丹尼 (d e n i e r)、3 0 0丹尼、6 0 0丹尼及7 5 0打尼時之排出側的紗 -18- 201229342 線張力測量結果顯示於表3至表6。又，將尼龍絲（PA6) 之紗線粗度爲1 40d的情況之排出側的紗線張力結果顯示 於表7。另外，在表3至表7中，係從表1之4種類的噴 嘴之中，適當地選擇對應於紗線粗度的噴嘴來使用。 [表3] (紗線種類)材質：PET，紗線粗度：75d/72fx2=150d201229342 VI. Description of the Invention: [Technical Field] The present invention relates to a yarn processing apparatus for generating a entanglement or loop (1 ο ο p) or the like to spray a fluid to a yarn to impart bulkiness to the yarn. [Prior Art] Conventionally, there has been a yarn processing apparatus which ejects a fluid from a yarn composed of filaments such as synthetic tree Q grease, and generates entanglement or entanglement by filaments. Etc., and impart fluffiness to the yarn. Patent Literatures 1 and 2 disclose a yarn processing apparatus including a yarn passage, a nozzle, and a spherical collision body, wherein the yarn passage has a yarn introduction portion and a yarn discharge portion, and the nozzle system is provided with a pair An air injection hole for compressing air is injected into the yarn passage; the spherical collision system is disposed to face the yarn discharge portion of the nozzle. In the yarn processing apparatuses of Patent Documents 1 and 2, the yarn introduced from the yarn guiding portion is discharged from the yarn discharge portion through the yarn passage that can be injected into the air. Here, the air from the yarn discharge portion collides with the spherical collision body and flows along the surface thereof, so that the yarn is multiplied by the flow of the air, and is discharged through the gap between the yarn discharge portion and the collision body. . At this time, the yarn may be returned to the filament due to the flow of air generated in the yarn discharge portion, and the yarn may be imparted with fluffiness. (Patent Document 1) Japanese Patent Publication No. 2000-514509 (especially, FIG. 5, FIG. 6 and FIG. 8) (Patent Document 2) Japanese Laid-Open Patent Publication No. 2000-303280 No. 201229342 [Description of Invention] Problem to be Solved However, in the conventional yarn processing apparatus using the spherical collision body, 'sometimes fluffy processing may become insufficient, and there is room for further improvement. Therefore, the inventors of the present invention have carefully reviewed the results for the above reasons, and found the following findings: the shape of the collision body has a great influence on the processing performance of the yarn processing apparatus, and can be improved by the shape of the collision body. Processing performance. SUMMARY OF THE INVENTION An object of the present invention is to provide a yarn processing apparatus having high yarn processing performance. (Means for Solving the Problem) The yarn processing device according to the first aspect of the invention includes a nozzle including a yarn passage and a fluid discharge hole, wherein the yarn passage includes a yarn introduction portion and a yarn discharge portion. The fluid ejecting hole ejects a fluid toward the yarn passage; and the collision body has a surface that faces the gap between the yarn discharge portion and the front end surface of the discharge port, and the collision body The opposing portion of the surface facing the front end surface of the yarn discharge portion and the discharge port are formed in a concave shape. According to the present invention, since the concave portion is formed by the opposing portion of the collision body facing the discharge port of the nozzle, a large space can be secured between the yarn discharge portion of the nozzle and the collision body, and it is easy to be in the space. Disturbing the flow of fluid. Therefore, it is easy to generate a loop or an entanglement in the filament "discharged from the yarn discharge portion by the intense fluid flow in the space", and the workability of the yarn -6 - 201229342 is improved. Further, the so-called improvement of the processing property of the yarn means that the processing quality of the same grade or higher can be achieved even if the processing is performed at a yarn speed faster than the conventional one, and the productivity can be improved. In the yarn processing device according to the first aspect of the invention, the inner surface of the concave portion of the collision body is formed by a curved surface. When the inner surface of the opposite portion of the concave portion of the collision body is a curved surface, since the fluid discharged from the yarn discharge portion together with the yarn flows along the inner surface of the inner portion 0 of the opposite portion, the fluid does not flow. In the yarn processing apparatus according to the third aspect of the invention, the yarn processing apparatus of the third aspect of the invention is characterized in that the yarn is more likely to be trapped in a localized manner, and the yarn is more likely to be looped or entangled in the filament. The opposite portion has a most concave shape at its central portion. When the opposing portion of the collision body has the most concave shape at the center portion thereof, the yarn discharged from the yarn discharge portion is concentrated to collide with the innermost deep portion of the opposing portion of the concave shape Q. Thus, by the concentrated collision of the yarn to one of the collision bodies, the subsequent yarn processing (loop formation or entanglement) is stabilized and the yarn processing performance is improved. In the yarn processing device according to the first aspect of the invention, the cross-sectional shape of the opposing portion of the collision body is an arc shape or an elliptical arc shape, and the cross-sectional shape of the opposite portion of the collision body is an arc. In the case of an elliptical or elliptical arc shape, the inner surface of the opposing portion is a curved surface and the central portion of the opposing portion is the most concave shape. Therefore, as described in the above-mentioned second and second inventions of the present invention, it is possible to further improve the processing property of the yarn because the fluid does not easily locally generate a loop or a parent's shape and the loop can be stably formed. According to a first aspect of the invention, in the first aspect of the invention, in the opposing portion of the collision body, the flat portion is parallel to the front end surface including the discharge port, and surrounds the concave portion . When the collision body is opposite to the entire portion of the discharge port, the end portion thereof has a sharp shape. In this case, the shape of the end portion of the body is not uniform, or the occurrence of the end portion has a great influence on the processing of the yarn. The tension of the specific thread is not uniform or causes a pile or the like. However, since the flat portion of the concave portion is formed in the opposing portion of the collision body, the shape of the end portion of the opposing portion is also less likely to be defective, so that the yarn is treated with the yarn of the sixth invention. In the first aspect of the invention, the nozzle holder for holding the nozzle is attached to the nozzle holder, and in the nozzle guide, the yarn guide # guides the collision body passing through the nozzle. The yarn that comes out between them. In order to make the yarn discharged from the yarn discharge portion of the nozzle, it is preferable to provide a yarn guide on the downstream side of the nozzle. However, the tension will be retained and easily produced or entangled when the yarn guide is additionally provided with the yarn guide according to the position of the yarn guide relative to the nozzle, and any of the fourth portions is formed with a concave portion and When the yarn discharge portion is concave, there is a case where a fine defect is caused, and the yarn is caused to be stable in the present invention and the unevenness of the surrounding. Any of the foregoing collision system seats of the fifth embodiment is provided with the yarn yarn discharge portion and the running stability thereof, which is changed by the yarn, and it is necessary to appropriately set the yarn tension to -8-201229342. : After the yarn processing device is set, the troublesome operation of the yarn guide relative to the position of the yarn processing device (nozzle) is further adjusted. In the present invention, since the yarn guide is further provided in the nozzle holder provided with the nozzle and the collision body, and the nozzle or the collision body and the yarn guide are integrated, the yarn processing device is disposed only in The predetermined position automatically determines the position of the yarn guide without the need to adjust the position of the yarn guide. According to the present invention, since the opposing portion of the collision body facing the discharge port of the nozzle is formed in a concave shape, a large space can be secured between the yarn discharge portion of the nozzle and the collision body, and It is easy to disturb the flow of the fluid in this space. Therefore, it is easy to generate entanglement or entanglement of the filaments discharged from the yarn discharge portion by the violent fluid flow in the aforementioned space, and to improve the processing property of the yarn. Further, the improvement of the processing property of the yarn means that the processing quality of the same grade or higher can be achieved even if the processing is performed at a yarn speed faster than the conventional one, and the productivity can be improved. [Embodiment] Next, an embodiment of the present invention will be described. Fig. 1 is a front view of the yarn processing apparatus of the present embodiment; Fig. 2 is a left side view of the yarn processing apparatus; and Fig. 3 is a schematic view showing a part of the yarn processing apparatus of Fig. 1 in a cross section. Further, Fig. 4(a) is an enlarged view of the nozzle and the collision body shown in Fig. 3, and Fig. 4(b) is a right side view of the collision body of Fig. 4(a) 201229342. In addition, the following directions are defined as the up, down, left, and right directions in the first and third figures. As shown in Figs. 1 to 3, the yarn processing apparatus 1' includes a nozzle 2, a nozzle holder 3 for holding the nozzle 2, and a collision body 4 provided in the nozzle holder 3. First, the nozzle 2 will be described. As shown in Fig. 3 and Fig. 4 (&), the nozzle 2 is formed into a cylindrical shape by a hard material such as metal or ceramic, and a flange which is bulging toward the radial direction is provided at one end of the nozzle 2. Department 2a. Further, a yarn passage 10 extending in the direction of the cylinder axis of the nozzle 2 is formed inside the nozzle 2. The yarn passage 10 has a yarn introduction portion 1 1 formed on the flange portion 2a side (right portion) of the nozzle 2, and a yarn formed on the opposite side (left portion) from the flange portion 2a of the nozzle 2. The wire discharge portion 1 2 and the air introduction portion 13 of the yarn introduction portion 1 1 and the yarn discharge portion 1 2 are provided with the yarn supply 3 at the end surface of the flange portion 2a located at the right end portion of the nozzle 2. In the lead-in port 1 1 a, the yarn introduction portion 11 is formed in a pointed shape in which the inner diameter is reduced from the introduction port 11 a toward the distal end side (the left side in the drawing). On the other hand, a discharge port i 2 a through which the yarn 3 1 introduced into the yarn passage 1 is discharged is attached to the left end surface of the nozzle 2 opposite to the flange portion 2a, and the yarn is discharged. The portion 1 2 forms a tail width shape in which the inner diameter is increased toward the discharge port 1 2 a. The shape of the yarn guide portion 1 1 of the pointed end or the yarn discharge portion 12 of the tail width can be, for example, a push-out shape or a flared shape in which the degree of expansion (curvature) at the open end is larger than the push-out shape. As an example, in the present embodiment, the yarn introduction portion u has a flared shape, and the yarn discharge portion 12 has a push-out shape. -10- 201229342 In the central portion of the nozzle 2 in the cylinder axis direction, an air injection hole 14 (fluid ejection hole) that opens toward the air introduction portion 13 of the yarn passage 10 is provided. Further, although only one air injection hole 14 is shown in Fig. 4(a), a plurality of (e.g., three) air injection holes 14 may be disposed at equal intervals in the circumferential direction of the nozzle 2, respectively. Further, the air injection hole 14 is inclined with respect to the front end side (left side) of the yarn passage 1 半径 in the radial direction of the nozzle 2 (direction orthogonal to the yarn passage 10), and is oriented at 0 toward the yarn. Passage 1 〇 When the air is injected, a strong air flow toward the left side is generated. Next, the nozzle holder 3 will be described. As shown in Figs. 1 to 3, the nozzle holder 3 has a rectangular parallelepiped shape which is slightly longer in the vertical direction. A mounting hole 20 that horizontally penetrates the nozzle holder 3 is formed at an upper side portion of the nozzle holder 3. Further, although the above-described nozzle 2 is inserted into the mounting hole 20, the diameter of the mounting hole 20 is smaller than the outer diameter of the flange portion 2a of the nozzle 2. Therefore, the left end portion of the nozzle 2 can be inserted into the mounting Q hole 20' from the opening on the right side, and the flange portion 2a provided at the right end portion of the nozzle 2 is not inserted into the mounting hole 20 but is abutted against the nozzle. The right side of the seat 3, whereby the 'nozzle 2' can be positioned relative to the nozzle holder 3. Further, as shown in Fig. 1, a restriction member 22 for preventing the nozzle 2 inserted into the attachment hole 20 from flying toward the right side is attached to the nozzle holder 3. An air supply hole 2 1 ' extending upward and downward is formed inside the nozzle holder 3, and the air supply hole 21 is connected to an air supply source (not shown). Further, when the nozzle 2 is attached to the mounting hole 2 of the nozzle holder 3, the air nozzle hole 14 formed in the nozzle 2 communicates with the air supply hole 21, and the air supplied from the air supply -11 - 201229342 to the hole 2 1 It can be ejected from the air injection hole 14 toward the yarn passage 10 . Next, the collision body 4 will be described. As shown in Fig. 3 and Fig. 4, the collision body 4 has a substantially disk-shaped outer shape and is formed of a hard material such as metal or ceramic. The collision body 4 is opposed to the left end surface of the nozzle 2 attached to the nozzle holder 3 (the front end surface of the yarn discharge portion 12 where the discharge port 1 2 a is formed) with a slight gap therebetween. Among the right side of the collision body 4 facing the left end surface of the nozzle 2, a central portion facing the discharge port 12a is formed as a recess 4a. The inner surface of the recessed portion 4a is located on a plane including a plane of the central axis of the nozzle 2, and is formed into an arcuate curved surface. Further, the concave portion 4a is surrounded by the flat portion 4b. The flat portion 4b has a flat surface parallel to the front end surface of the yarn discharge portion 丨2. In addition, the configuration in which the collision body 4 is held at a position facing the discharge port 1 2 a of the nozzle 2 is not particularly limited. However, in the present embodiment, the following configuration is adopted as an example. First, as shown in the figure, the base member 2 3 ' is fixedly attached to the left side surface of the lower portion of the nozzle holder 3 by a bolt or the like, and the mounting base member 23 is rotatably coupled in the vertical plane. The block-shaped holder 24 is at the lower part. Further, one end of the connecting rod 25 is fixed to the holder 24, and the collision body 4 is fixed to the other end of the connecting rod 25. In this configuration, as shown by the two-dot chain line of Fig. 3, when the holder 24 is rotated with respect to the mounting base member 23, the collision body 4 is also integrally rotated 'and the collision body 4 can be spread over the following two positions. The movement is a position opposite to the discharge port 1 2 a of the nozzle holder (a position indicated by a solid line) -12-201229342, and a retreat position (a position indicated by a two-dot chain line) away from the discharge port 1 2a. Then, by moving the collision body 4 to the retracted position, the threading operation into the nozzle 2 can be easily performed. Further, in order to stabilize the travel of the yarn 3 1 discharged from the yarn discharge portion 12 of the nozzle 2, it is preferable to provide a yarn guide on the downstream side of the nozzle 2. However, the tension of the yarn on the downstream side of the nozzle changes with the position of the yarn guide relative to the nozzle 2. Therefore, when the yarn guide is separately provided in addition to the yarn processing device 0 1 , in order to appropriately set the tension of the yarn, it is necessary to further adjust the yarn guide after the yarn processing device is provided. The troublesome operation with respect to the position of the yarn processing device 1 (nozzle 2). Therefore, as shown in FIG. 1 and FIG. 2, in the present embodiment, the attachment base member 23 fixed to the nozzle holder 3 is provided with the yarn discharged from the nozzle 2 through the attachment member 27. Guided yarn guide 26. That is, the nozzle holder 3 provided with the nozzle 2 and the collision body 4 is further provided with the yarn guide 26, and the nozzle 2 or the collision body 4 and the yarn guide 26 are integrally formed. Then, the yarn which is discharged from the right side of the first drawing into the nozzle 2 and discharged from the yarn discharge portion 12 can pass through the yarn guide which is located on the front side (the right side in Fig. 2) of the first drawing. Guide upwards. As described above, by integrally configuring the yarn guide 26 and the nozzle holder 3, the position of the yarn guide 26 can be automatically determined as long as the yarn processing device 1 is set at a predetermined position, and adjustment is not necessary. The position of the yarn guide 26 relative to the nozzle 2. Next, the operation of the yarn processing apparatus i of the present embodiment for the fluffy addition of -13 to 201229342 will be described. First, as shown in FIG. 1 to FIG. 3, the yarn 31 composed of filaments such as synthetic resin can be introduced from the introduction port 1 1 a of the yarn introduction portion 1 1 provided in the nozzle 2, and The air introduction portion 13 is guided. Further, the air supplied from the air supply source not shown in the drawing is jetted to the air introduction portion 13 by the air injection hole 14. The air jetted to the air introduction portion 13 is discharged from the yarn discharge portion 12 and further collides with the collision body 4 disposed to face the discharge port 12a, and the air flows at this time. The yarn 3 1 is from the collision body 4 It is discharged to the gap between the yarn discharge portion 1 2 . At this time, the constituent filaments of the yarn 3丨 can be opened by the violent air flow in the yarn discharge portion 12, and the loop or the entanglement or the like can be generated by the violent movement of the respective filaments. The yarn 3 1 is provided with bulkiness. Here, in the yarn processing apparatus 1 of the present embodiment, the concave portion 4a is formed on the surface of the collision body 4 facing the discharge port 12a. Therefore, a large space can be secured between the yarn discharge portion 12 of the nozzle 2 and the collision body 4, and the flow of the air is easily disturbed in the space. Therefore, since it is easy to generate a loop or an entanglement of the filament discharged from the yarn discharge portion 1 2 by the intense air flow, the processing property of the yarn can be improved. Moreover, the improvement of the processability of the yarn processing apparatus 1 means that even if it is processed at a yarn speed faster than the conventional one, the processing quality equivalent to the conventional one can be obtained, the productivity can be improved, and the processing can be reduced. The amount of air required for a yarn per unit length. Further, in the present embodiment, the concave portion 4a of the collision body 4 is formed by a continuous curved surface having a circular arc shape. When the concave portion 4a is formed by a curved surface, -14-201229342, the air discharged from the yarn discharge portion 12 together with the yarn, the space inside the portion 4a flows along the inner surface thereof, so the air is not retained. It is easier to produce crepe or entanglement in the filaments. Further, the concave portion 4a' is formed in the central portion (the position at the center of the nozzle 2) to form the most concave shape, and the yarn is discharged from the yarn discharge portion 1 2 to collide with the innermost deep portion of the concave portion 4a. Thus, by the concentrated collision of the yarn to one of the collision bodies 4, the yarn processing (loop formation or entanglement) can be stably performed, and the yarn is further increased. In the present embodiment, it is attached to the collision body 4. The opposite portion of the sputum is provided with a recess 4a and a 4b for surrounding the recess. In this case, 'the whole shape of the opposing portion of the collision body 4' is sharper than the end portion (outer peripheral portion) (Fig. 5 (e) of the state listed later). The unevenness of the shape of the opposing portion (outer peripheral portion) is small, and the defect is not easy to be 0. Therefore, the processing of the yarn can be stably performed. Further, although the outer diameter of the collision is set to D, the diameter of the concave portion 4a is set to d, and when the flat portion is set to t, it becomes D = d + 2t, but the flat portion 4b t' is preferably The decision is within 5 (mm). In addition, the present invention is not limited to the above-described embodiments, and the following descriptions are appropriately changed as long as they are not departing from the scope of the present invention. 1] The concave shape of the collision body 4 with respect to the discharge port 12a of the nozzle 2 is not limited to the cross-sectional arc shape of the above-described embodiment, and the concave shape is easy to be localized. • Come, borrow; 1 work performance after the line i □ 12a I flat part: change shape into a concave shape; the end of the branch occurs, the width of the width of the body 4 4b can be applied as part of the "". For example, -15-201229342, as shown in Fig. 5, may be used as the cross-sectional shape of the concave portion 4a, such as (a) elliptical arc shape, (b) pot bottom shape, (c) trapezoidal shape, (d) conical shape, or the like. In addition, in the elliptical arc-shaped recessed portion 4a of the above-mentioned (a) to (d), the arcuate recessed portion 4a of the above-described embodiment is the same as the arcuate recessed portion of the above-described embodiment (see Fig. 4), The curved surface is formed, so the air flows along its inner surface without the valley being liable to be localized, and it is easy to generate a loop or entanglement in the yarn. Further, in the elliptical arc shape of (a) and the conical shape of (d), since the center portion is most recessed, the yarn is concentratedly collided into the innermost deep portion of the collision body, whereby the subsequent operation can be stably performed. Yarn processing. Further, as in the fourth embodiment of the above-described embodiment, the recessed portion 4a is provided only on a part of the surface of the collision body 4 on the side of the discharge port 12a, and the periphery of the recessed portion 4a does not necessarily need to be surrounded by the flat portion 4b, and the fifth portion is also required. Similarly to the diagram (e), the entire surface of the collision body 4 on the side of the discharge port 12a may be configured as a recess 4a. 2] The nozzle 2 is not limited to the shape of Fig. 4(a) of the above embodiment. For example, as shown in Fig. 6(a), the yarn introduction portion u may be in a push-up shape, and the yarn discharge portion 12 may be in the form of a squad. Alternatively, as shown in Fig. 6(b), the yarn introducing portion 1 1 may have a straight shape in which the diameter does not change. 3] Although the collision body 4 is configured to be movable (rotated) with respect to the nozzle holder 3 in the above embodiment, the collision body 4 may be fixed to the nozzle holder 3. [Embodiment] Next, a specific embodiment of the present invention, The comparative examples are described in comparison. -16-201229342 (1) Specifications of nozzles and collision bodies The four types of nozzle specifications used in the examples and comparative examples are shown in Table 1, and the nozzle specifications of the six types are shown in Table 2.

Further, the No. 3 nozzle and the No. 4 nozzle of Table 1 are nozzles shown by (2) on the left side of Fig. 7 . However, as shown in Table 1, in the No. 1 nozzle and the No. 2 nozzle, the diameters of the air injection holes are different, and the applicable yarn thickness range has a certain deviation (No. 1 nozzle is a fine yarn) For the thread, the No. 2 nozzle is used for thick yarn). The same applies to the No. 3 nozzle and the No. 4 nozzle -17-201229342. Further, as shown in Table 2, in the case of the collision body, the collision portion (Cup) of the three types of the embodiment to which the present invention is applied is formed by using the nozzle and the opposite portion of the discharge port, as a comparative example. There are six types of a total of two types of spherical collision bodies (Ball) and one type of flat-shaped collision bodies (piate). In Fig. 7, '(a) and (e) are spherical collision bodies of 13 mm, (b) and (f) are spherical collision bodies of 6 mm, and (c) and (g) are flat collision bodies, ( d), (h) is a concave collision body of the present invention. In addition, all six types of collision bodies are made of ceramics. (2) Comparison of processing performance due to the difference in the shape of the collision body The review of the processing performance of the yarn processing apparatus due to the difference in the shape of the collision body was reviewed. That is, the nozzles of Table 1 and the collision body of Table 2 were combined, and the material of the yarn and the thickness of the yarn were changed and experiments were respectively carried out, and the yarn on the downstream side (discharge side) of the nozzle was measured for each experimental example. tension. Here, the core yarn and the pattern yarn are processed by supplying a core yarn and an effect yarn to the nozzles at different supply speeds and processing them. Further, the yarn speed (discharge side yarn speed) on the downstream side of the nozzle was changed in four stages' and "the excess feed amount to the respective core yarns and the pattern yarns (the amount of yarn supplied to the nozzles ( The yarn tension (unit: gr) on the discharge side at the time of "fixed time" of the supply-side yarn speed) with respect to the discharge yarn amount (discharge-side yarn speed).

This point is shown in Tables 3 to 7 'No matter about the material of the yarn, the thickness of the yarn, and the type of the nozzle, in the case of using the concave collision body (Cut) of the present invention (Example) Spherical collision -22- 201229342 In the case of a bump or a plate-shaped collision body (comparative example), the yarn tension on the discharge side is higher. In other words, it can be understood that the processing property of the yarn of the yarn processing apparatus can be considerably improved by using the concave collision body. Further, it can be understood from Tables 3 to 7 that generally, the lower the yarn speed, the higher the yarn tension on the discharge side, and the yarn processing tends to be excellent. In this regard, when a spherical collision body or a flat collision body is used, it is necessary to reduce the yarn speed when it is desired to achieve a certain processing quality (a certain or more yarn tension), but by using this The concave collision body of the invention can produce a yarn of a quality equal to or higher than that of a spherical or flat plate at a faster yarn speed, and can greatly improve productivity. For example, in Table 5, it can be understood that a spherical shape The collision body (Ball) or the plate-shaped collision body (Plate) reduces the yarn speed to a low speed of 3 50 m/min to barely reach a tension of 11 gram; in contrast, the concave collision body (Cup) Q is even improved. When the yarn speed is 500 m/min, the tension of more than 11 g can be achieved, and the quality equal to or higher than that of the spherical collision body or the flat collision body can be obtained. (3) Diameter of the concave portion of the concave collision body Next, the processing property of the yarn when the diameter of the concave portion of the concave collision body (dimension d shown in Fig. 7) is changed is reviewed. Here, the experiment was carried out by using three kinds of colloids having a concave portion diameter of 11 mm, 20 mm, and 24 mm in Table 2 and a flat collision body as a comparative example, and changing the thickness of the yarn -23-201229342. The yarn tension of the discharge side when the material of the yarn is PET and the yarn thickness is 150 denier, 300 denier and 600 denier are shown in Table 8 to Table 10.

Compared with the case of using a plate-shaped collision body of flat-25-201229342, the 'yarn tension becomes high' and the workability is improved. Further, when the diameter of the concave portion ' of the collision body is extremely small or extremely large with respect to the diameter of the opposite discharge port, the effect of improving the workability is small. Regarding this, in Tables 8 to 10, the parameter of the dimensionlessness of the ratio of the discharge port diameter (κ) of the nozzle to the diameter (d) of the concave portion of the collision body (ε = K/d) has been described, and at least Understand: In the range of ε from 0.25 to 1.18, the processing performance is better.
