經濟部智慧財產局員工消費合作社印製 436448 A7 _____B7_______ 五、發明說明（1 ) 根據申請專利範圍第1項，本發明是關於一種用以熔 接塑膠製管狀容器特別是管的端部之裝置。 有許多種呈可澆注形式或是糊狀的材料均是包裝在管 內，例如化粧器、牙膏、鞋油、乳液及類似物品。這些管 是由具延展性的適當扁平金屬材料所製成。但是塑膠材料 也已被使用相當長的時間，主要是因爲經濟的理由。 在封合端部之前，管狀容器之胚料內會先充塡以要包 裝在其內的物質。可取開的一側則是以一適當之蓋加以封 閉，例如螺紋狀之蓋或類似之物。而其用以塡充之端部則 在塡充作業後加以封閉。在使用延展性扁平材料時，傳統 上會在塡充末端處形成一條摺疊線。另外可選擇性地在此 端部區域內進行線性的壓合作業，以確保能有適確的封合 效果。此種方法無法使用在塑膠材料上。反之，其接合起 來的端部必須要加以熔接或封合在一起。 專利文獻D E 37 44 4 0 2 C2中掲露一 種用來封合塑膠製管狀容器的方法，其末端部位是在由加 壓裝置加工形成封合接口之前，先藉由施加熱或類似者而 加以軟化或熔化。 因此其軟化作業是藉由將一個具有多個噴嘴的環狀物 置放在該塡充端部處，以將熱空氣吹至該管之塡充端部的 外壁上。由於一般均需要完全地熔接，因此必須要施用相 當大量的熱，亦即需要約高達1 8 k W的電能。此方法 是目前包裝工業中所使用的，被稱爲‘‘熱氣”法。 類似於熱氣法，習用止亦有藉由超音波或微波輻射而 --------4-___ 本紙張尺度適用中國國家標準（CNS)A4規格（210 X 297公釐） --------- —I—^ ------^—訂---------線 V (請先閱讀背面之注意事項再填寫本頁) 經濟部智慧財產局員工消費合作钍印製 43 64 4 8 A7 ___B7____ 五、發明說明（2 ) 將要加以熔接的末端加以軟化或熔。 由於用來熔化的裝置和用來壓合的裝置，並不會具有 相同的空間關係，因此這些方法均需要在連續的不同步驟 中分開來進行熔化和後續的壓合作業。此外，由於會發生 不必要的延展性變形，而且此產品可能會受熱損傷之故， 因此在壓合作業後，通常需要將原先加熱過的管加以冷卻 。由於此一額外的冷卻步驟之故，此方法是相當的浪費。 專利文獻DE 2.2 6 1 388中掲露一種用來 將一個塑膠製之末端件熔接在管狀塑膠物體上的方法，其 中該末端件，其係具有管狀的截面，係插入至該管狀本體 內。並以雷射照射該管狀本體的外側，而該管及該末端件 則被加以旋轉。壓合滾輪用以將加熱之區域加以壓合在一 起而進行某種型式的熔接作業。 本發明的目的在於提供一種用來熔接管狀容器特別是 管的端部之方法及裝置，其可使用在所有形式的習用管狀 塑膠件上，且僅需要少量的能量消耗 > 即能得到高生產速 度和適切的技術效果。 此一目的可藉由申請專利範圍第1項中之特徵而達成 c» 藉由本發明之裝置，其可設置一個最好是呈多件式之 固持器，以供將多個雷射二極體單元約略設置在一圓上， 而使其等之光束能直接或經由一種折射光學裝置而投射至 該容器的外壁或內壁上。 二極體雷射的波長是在近紅外線的區域（約6 5 0 _________- 5 ___ __ 本紙張尺度適用中國國家標準（CNS)A4規格（210 X 297公釐） ------- J----- ------.—訂---------線 (請先閱讀背面之注意事項再填寫本頁) 436448 A7 B7 五、發明說明（3 ) nm至1400nm)，至於是要照射此容器之內壁或外 壁，則舉此裝置之功效無關的，因爲幾乎所有能用的塑膠 均能部份地吸收照射光束，而使得照射光束能夠均勻地作 用在整個壁厚（少於1mm)上。爲簡化機器結構，應該 是要照射外壁。因此在壓合在一起之作業中所需要有之內 壁熔化的情形可以經由照射外壁而達成。本發明的方法能 夠提供熔化區域印均勻加熱效果。在改善其功效上，其亦 可設置一個反射器於容器內部，位在不面對雷射二極體的 一側，以將照射光束反射回至其材料上。 由一個雷射二極體或是雷射二極體陣列發射出的光束 會強烈地發散開，通常在雷射二極體的縱向延伸方向（慢 軸）所在的平面上是約6至1 0度，而在垂直於該縱長延 伸方向的雷射二極體橫向延伸方向（快軸）的平面上則爲 約3 5至4 0度。此種狀況可以爲本屬明之裝置加以部份 地利用。爲能沿著容器的周邊以雷射投射光做連續的接合 作業，其可以假設雷射照射光束的快垂直軸（約1 〇度） 可以決定雷射二極體單元在設置在一圓上時與該容器間的 徑向分離間距。爲能在周邊方向上達到連續不斷的照射結 果’可以自快軸之平行照射角的數値上減掉〇 . 2度的數 値。 此雷射二極體的照射光束應該要加以聚焦，以得到足 夠的能量密度（根據目前的經驗，此能量密度鹰該是 > 2 0 W / m 2 )。爲能得到此一能量密度，例如雷射二極 體單元的慢軸應加以強烈地聚焦。其可以聚焦至〇 . 5 本紙張尺度適用中國國家標準（CNS)A4規格（210 X 297公釐） f請先閱讀背面之注意事項再填寫本頁) ο裝-----^---訂---------線 經濟部智慧財產局員工消費合作社印製 -6- 經濟部智.¾財產局員工消費合作社印製 436448 A7 _______B7__ 五、發明說明（4 ) mm內而不會有任何特別的困難度。另一方面，照射在容 器之周邊方向上的雷射光束則是例如僅稍微地聚焦，以便 調整照射的模式。因此最佳的聚焦結果是如下。慢軸是聚 焦至0 5 m m內=快軸則不加以聚焦，而維持約4 5度 的照射角度。在此種情形下，一個雷射單元可以照射管狀 物體之周邊上的一個0 . 5mmx4 5度的周邊面積。就一 個25mm之管內徑而言，4 ◦度相當於9 . 8mm。這 可得到一個4 . 9 m m. 2的照射面積。就2 0 W的雷射輸出 功率而言，此可以造成約4 〇 W/ c m 2的能量密度。 可以利用一個非球面透鏡來調整雷射光束的焦距至該 圚柱狀表面的曲率上。也可以增加雷射二極體單元的數量 ’直到其聚焦深度足以補償該曲率，以克服此種狀況。因 此快照射軸會被聚焦成爲能提供1 〇度的照射角。此一 1 0度的角度可使其能用較小的管狀容器的表面曲率値， 這在某些情形下，甚至可以不用再以光學的方式來做補償 ύ 雷射二極體的機械式定位作業同樣是依焦距而定的。 雷射二極體單元的相對位置必須要隨著容器的圓周而改變 。因此容器壁上的能量密度會成比例的減少。在此種情形 中，同樣的，雷射二極體單元可以設置在互相分離開而僅 對應於快軸照射角之一部份的位置上，以補償此一能量密 度減低。如前面已提到的，這可減輕有關於容華表面之曲 率的問題。 在一種簡單的結構中，雷射二極體單元可以設置在對 本紙張尺度適用中國國家標準（CNS)A4規格（210 X 297公釐） I I 1—1-Γ I ----^ J * 1 I I 1 I i-*-rOJ - - - - - - - I (請先閱讀背面之注意事項再填寫本頁) A7 436448 _B7_ 五、發明說明（5 ) 應於它們之正向照射特性的位置上（約4 5度垂直照射角 )。這需要八個雷射二極體單元繞著容器之軸心線設置。 爲能將上述結構中的能量密度增加至2 0 0 %，雷射二極 體間的軸向分離間距必須要減少至約2 2 . 5度。 爲能配合於管狀容器的直徑或是在入射點上改變能量 密度，本發明的一種實施例是將雷射二極體單元在其它的 縱向軸心線的方向上移動。因此要設置適當的移動裝置， 並以適當的方式來配合.，以達成雷射二極體單元的移動作 ° 可以使用一種圓形或環狀的結構來承載及移動該等雷 射二極體單元，其可以包含有多個各別的部件，每一者支 撐一個雷射二極體。因此這些部件的數量是等於雷射二'極 體單元的數量。每一部件可以被個別地承載，以供沿著其 縱向軸心線移動。所有的部件均被共同設置一個環狀的支 架上。 本發明的另一種實施例中，該部件支架的高度是可針 對所有的部件做調整的。這可使得入射至容器外壁上的位 置可以改變。 除了上述的雷射二極體以外，光纖結合二極體雷射（ Fiber Coupled Diode Laser )或是光纖雷射（Fiber Laser ) 均可以同樣的方式使用。這些輸出用的光學裝置必須要根 據雷射之型式而做調整。 本發明將配合圖式中所示之實施例來加以更詳細地說 明0 本紙張尺度適用中國國家標準（CNS)A4規格（210x 297公釐） ------< I J----- I、----I 4 I I 訂· ------II *3^ {請先閱讀背面之注意事項再填窝本頁) 經濟部智慧財產局員工消費合作社印製 -8- 436448 A7 B7 五、發明說明（6 ) 圖1顯示出本發明之裝置的示意表示平面圖。 圖2顯示出圖1中沿著線2 — 2的剖面圖》 圖3顯示出圖2的另一種實施例。 圖4示意地顯示出本發明之裝置中所用的二極體雷射 單元的平面圖。 圖5是圖4中之雷射二極體單元的側視圖。 主要元件對照表 1 0 管 狀 容 器 1 2 固 持件 1 4 二 極 體 雷 1 6 微 透 鏡 1 8 重 疊 部 份 2 0 連 接 板 2 2 螺 栓 ------1--J----f ------'--訂---------線 (請先閱讀背面之注意事項再填窝本頁) 經濟部智慧財產局員工消費合作社印製 圖1和圖2中所示的管狀容器10是由一種具有相當 薄壁部的塑膠材料所製成。此容器的底端是封閉的，而其 頂端則是開放的。此開放端部接著將會在二個線性移動的 爪部之間加以壓合在一起而形成一個橫向的長條狀溶接封 合接合部。就此而言，用來製做容器1 0的適當塑膠材料 首先必須要加以軟化。此軟化作業是藉由圖1和圖2中所 示之裝置內的雷射光束之助而達成的。 圖1中顯示出八個長條狀的固持件12，其如圖2中 9 本紙張尺度適用中國國家標準（CNS)A4規格（210 X 297公釐） 經濟部智慧財產局員工消費合作社印製 4 3 G 4 4 B a?
