部份。 相關技藝說明 一用於附接一上止件及一可分離下止件部份（工具缺乏 部份）之間隔部份，係間歇地形成於一供具有該可分離下止 件之滑勤拉鏈使用的拉鏈串内。該可分離下止件係附接至 間隔部份。在附接可分離下止件前…由合成樹脂形成之 強化帶片-通常先接合至拉鏈串之可分離下止附件部份而 以強化。 '
強化帶片之接合設置方式係失待拉鏈牟間隔部份内之相 對帶側緣，而一中心線經編織至拉鏈串之各個相 使其因而變厚。當整個強化帶 ^ 片错由壓力同時接合至一 /1 部份及一扁平部份時，皱摺及_ ^ ，強化帶片之接合設置易於破損u 再者 欠颂。為解決此問題，例仳γ 示於日本專利第jp-b-62_5 丨女知 霄片係經二階段接合而形成一體。 、化 例如在JP-B-62-54001 中，於 Α α 設置-強化帶片於垂直拉鏈串：=鏈串每-次傳送停止時 緣與下緣經彎折而經由間隔部如強化贡片之上 77之内惻與外側失持該強化 ^ 6 - 587983 v; mmmmm 片。經強化帶片夾持之中心線部份及其鄰近之主帶部份接 著從内侧與外側加壓與加熱，以接合一部分之強化帶片至 中心線部份，及隨後設於鄰近接合區域之強化帶片及帶部 份未接合之區域被從内側與外側加壓及加熱而將其二者完 全接合而形成一體。 此外在JP-B-63-40085中，由熱塑性樹脂形成具有固定尺 寸的-強化帶片，*滑動拉鏈串間隔部份内強化帶附接部
份的上、下二側邊，跨接於拉鏈帶之左右相反邊緣。強化 帶片係置於超音波之振盪頭及砧塊之間加壓嵌入。超音波 振盪頭包括符合左、右拉鏈帶之中心線的一直線内凹溝槽 ，及中心線外端之切刀片。砧塊包括同樣符合左、右拉鏈 帶之中心線H線内凹溝槽’ &中心線外端之切刀片。 接著實施超音波處理而使強化帶片熔接至左、右拉鏈帶之 中、、泉夕j 4周邊及其鄰近之帶部份，1同時設置於相對中 心線之間的強化帶片被切斷，而後強化帶片之餘留部份經 加壓與加熱熔接至各個左、右拉鏈帶的二面。 77 — 方面，例如 JP-B-2-3566 1 與 JP-A-63-3 1 5223 均曾揭 使用超音波«於料之控制m中㈣頭之溫度 =測以控制振盈頭之超音波振㈣度。在該控制方法中 〜J方法之κ %係使一溫度偵測元件（例如一溫度計）附 方:一加壓工具或-接收部份以偵測溫度，超音波振盪之 1在溫度低時增加而當溫度高時幅度減低。此夕^ 一 乂 丨4〇823與Jp-A-5-299480中所揭示，例如偵測包 ;熱叹備(例如-加熱器)之超音波振盪頭的溫度，而 587983 0) [m萌說钥繽頁 控制加熱設備以維持振盪頭之溫度為固定 依據揭示於 丨 ％ ϊρ r《/λ -與 JP-B-63-40085 中有關強化 π片的各接σ (k接）技藝，一拉鏈帶之中心線部份與其鄰 近的帶部份在第一階段經熔接以由一強化帶片固持，而強 化帶片餘留未炫接區域在第二階段絲接於拉鏈帶以便實 施二階段整合。在㈣·62_5_中之實施係假設經由黏著物

如上述，需要嚴格控制使用加熱器於熔接之加熱溫度與 處理時間。如果任一者有所不足，就會產生接合失效。如 果任一者太過，強化帶片接合拉鏈帶處會呈熔融狀態。因 而拉鏈帶會產生易碎與過度硬化，以致其可能痕容易寶折 或損壞。另外，使用加熱器用於處理加熱熔接比一般超音 波烙接要化更長之時間。如在jP-B-63-4〇〇85所揭示之情形 中，其中使用加熱器加熱之熔接步驟係在超音波熔接後實 施，二者之差異在於處理之時間。如果為避免因接合失效 而產生脫離現象，而增加加熱器之加熱溫度以彌補與超音 波炫接處理時間之間的差異，此時通常容易產生過度加熱 以致熔接部份會變成硬化而易碎。此外，在以加熱器實施 加熱的情況下，氣泡容易在中心線部份與主帶部份間產生 另一方面，在以此方式將強化帶片接合於拉鏈帶之間隔 (4)587983 煢明:說钥續_ 設置通常藉由模具成型與 部份之設置。另一方面， 片接合至拉鏈帶之主帶部 面之設置。在適當條件下 有熔接表面經由内部加熱 表面係完美地完成而不會 用單一超音波振盪頭與單 線部份與主帶部份，在炫 以相同幅度實施於拉鏈帶 方面，由於如上文說明加 因此在超音波振盪時，需 面作用在拉鏈帶中心線部 、 與石占塊之成型表面作用在 塊之加壓表面經設定相對 強力加壓以獲得相對於中 起曰波、丨各接以相同幅度在 貫施時，過度的能量將傳 。結果，中心線部份之強 心線部份在許多情況下將 部份的情況下，強化帶片之夾持 炼接而均勻配置以便決定中心線 只要能維持一接合強度，強化帶 十77足以簡易實施而無須改變其表 藉由超音波加熱實施熔接時，只 而4、融及接合。因此，經處理之 變形。 如果如jP-A_5-299480所揭示使 一 4塊’同時熔接拉鏈帶之中心 接時超音波振盪係在相同時間内 之中心線部份與主帶部份。另一 壓與模具成型係在同時間實施， 求超音波振盪頭與站塊之成型表 份的壓力，應小於超音波振盪頭 拉鏈帶主帶部份的壓力。 然而，習知超音波振盪頭與砧 於拉鏈帶係輕微夾持，而設定為 心線部份的一預定斷面設置。當 相同時間内以此一加壓表面設置 送至具有較大壓力之中心線部份 化帶片部份將大幅度熔融以致中 硬化而易碎。 發明概要 本發明已達成解決習知問題且提供一 溶接方法之目的 (5) (5)587983 縈明說钥繽頁 其藉由超音波加熱在適當條 -主帶部份，以溶接一㈣· 線部份與 熔接裝置。 ㈣串m隔邹份與其 於ΓΓΠ二：藉由超音波炫接方法用於熔接-強化帶 x明弟—特點之主結構的拉鏈帶而有效獲得。 或―構之特徵在於藉由超 熟拉鏈f之中心部份 m㈣接由合成樹脂形成之於中心部份與鄰近中 ……接時間及/或幅度，及適於㈣強 帶部份的一稼接時間及/或幅度，及基於設定之嫁接時間戈 幅度Γ容接強化帶片於中心部份與鄰近中心部份處以稼接 強化帶片於主帶部份。 此外如第五與第九特點，本發明關於用於實施本發明相 關f法之適當炫接裝置，其特徵在於-具有滑動拉鏈串可 分離下止附件内之拉鍵帶的中心部份與主帶部份的外部設 置之超音波振盈頭與石占塊’及一連接至超音波振逢器之控 市J «丨h連接至超音波振盈頭而具有一時間及/或幅度設定 部份’能分別設定適於溶接強化帶片於令心部份與鄰近令 心部份處，與適於炫接強化帶片於主帶部份之@接時間及/ 或幅度。因此在本發明令’預期之目的可藉由只設定炫接 時間與幅度中之一而達到，而也可同時設定熔接時間與幅 度二者。 4皆由此一結構，強化帶片及滑動拉鏈串之可分離下止附 件内拉鏈帶之中心部份與主帶部份可在適當條件下分別經 超音波熔接。因此，可避免中心部份成為易碎與硬化，及 -10 - (6) (6)587983 發明說钥續頁 可避兄主π部份熔接…且再者可避免在使用滑動拉錢 時強化帶片脫離主帶料。此外’超音波炼接係在滴， 件下實施。因& ’在炫接表面產生之氣泡可藉由超音波振 盛有效地予以移除。所以可避免氣泡餘留在熔接表面，以 致實施加工後可具有高透明度。 如本發明之第二特點，適於熔接強化帶片於中心部份I 鄰近中心部份處之炫接時間及/或幅度，最好設定為小於適 於炫接強化帶 >；於主帶部份之炫接時間及/或幅度。超音波 熔接是否能正確實施取決於熔接時間、壓力與幅度。如上 文之說明’在熔接強化帶片之同時中心部份將被模具成型 為具有一符合需求之斷面。因此，將施加於中心部份之壓 力係大於將施加於主帶部份之壓力。例如，在用於中心部 份與主帶部份之炫接時間被設定成彼此相同之情況下，中 心部份之幅度經設定為較小以配合較大之壓力。此外，在 幅度被設定為彼此相同之情況下，中心部份之熔接時間經 設定為短於主帶部份之、J：容接時間。 本發明第三與第四特點指向該熔接方法，其中熔接強化 帶片於中心部份與鄰近中心部份之主帶㈣，以騎接強 化带片於主帶部份係獨立且分開實施，或者是熔接強化帶 片於主帶部份以及依次地熔接主帶部份、強化帶片於中心 部份與主帶部份鄰近中心部份係在相同時間。 因此例如依本發明第六特點，超音波振盪頭係由一單一 振盈頭形 而砧塊係設置有—第一砧塊用於支撐一對中 匕斗彳77興一對鄰近中心部份之主帶部份於滑動拉鏈串内， -11 - 587983
