Description

1296294 玖、發明說明: 一、 發明所屬之技術領域 本發明係關於一種縫紉機,其在待縫製材料沿著單一方 向進給之時,被用來形成一個包含有完美縫線之獨立縫合 線及在问一*線上包含有夠住縫線的另一^條獨立縫合線。 二、 先前技術 在運動比賽等使用的球中,每個縫合線會承受高負荷, 並且縫紉線會鬆弛,並且縫合線會裂開。本發明申請人已 提出一種生產強的縫合線之方法,其係由形成一個包含有 完美縫線(即一般縫線)之獨立縫合線及在同一線上(即兩縫 合線重疊)包含有鉤住縫線(其中針線被絞纒在具有鉤圈之 每個結上)的另一條獨立縫合線。 目前並未有生產此種強的縫合線之特別縫紉機;但是, 此縫合線可使用或被稍做改進的既有縫紉機,並且亦可改 進縫紉方法而生產之。 例如’上述縫合線可由具有如第5圖所示之梭鉤及針的 結構之縫紉機而生產。在縫紉機中,朝反時鐘或順時鐘方 向轉動之左側水平梭鉤1 01、左側針102、右側針103、及 與梭鉤1 0 1同方向轉動之右側水平梭鉤1 04被排成一直 線,並且左側針102及右側針1〇3在方向A(垂直於梭鉤及 針對齊.之方向)中搖動,以將待縫紉之材料進給。 使用此縫紉機之時,爲了形成一個包含有完美縫線之獨 立縫合線及在同一線上包含有鉤住縫線的另一條獨立縫合 線’首先縫紉機之進給機構被移開,以禁止針搖動。然後, 在材料以手工方式朝向方向B(朝向雙箭頭中的一個箭頭所 1296294 指示之方向)移動之時進行縫紉。縫紉動作使梭鉤丨0丨及右 側水平梭鉤1 04朝順時鐘方向轉動。當待縫紉材料向右移 動(即移到第5圖之右側)之時,完美縫線被左側針102所產 生,而鉤住縫線則被右側針1 03所產生。當待縫紉材料向 左移動之時,完美縫線被右側針103所產生,而鉤住縫線 則被左側針1 0 2所產生。另一方面,當左側水平梭鉤1 i 及右側水平梭鉤1 04朝反時鐘方向轉動、且待縫紉材料向 右移動之時,完美縫線被右側針1 03所產生,而鉤住縫線 φ 則被左側針102所產生。反之,當待縫紐材料向左移動、 且梭鉤101及右側水平梭鉤104朝反時鐘方向轉動之時, 完美縫線被左側針1 02所產生,而鉤住縫線則被右側針! 03 所產生。 形成此縫合線的方法亦可使用顯示於第6圖之部分(1) 及部分(2)所示的縫紉機而進行,其係分別使用水平梭鉤及 垂直梭鉤。每個縫紉機具有單一梭鉤105及單一針106,並 且待縫紉材料係朝向垂直於配置有梭鉤及針的方向A-B (見 _ 參考符號A及B之間的雙箭頭)而進給。爲了以上述縫紉機 形成一個包含有完美縫線之獨立縫合線及在同一線上包含 有鉤住縫線的另一條獨立縫合線,在第1縫合線朝向通常 進給方向A而縫紉之後,第2縫合線從位置X(即第1縫合 線之起點)或相反方向B中之位置Y(即第1縫合線之終點) 被縫紉,使第1縫合線及第2縫合線被形成在相同的線上。 在此情況下,第1縫合線包括有完美縫線,第2縫合線包 含有鉤住縫線。 在使用第5屬之縫紉機而形成完美縫線之獨立縫合線及 1296294 鉤住縫線的獨立縫合線之中,待縫紉材料係以手工方式進 給;因而,縫紉之節距及方向係可變化,並且縫合線之強 度在整個縫合線上係可改變。除此之外,作業效率被降低。 在使用第6圖之縫紉機而形成完美縫線之獨立縫合線及 鉤住縫線的獨立縫合線之中,縫紉係在一般及相反方向上 進行;因而,縫紉時間係爲單方向縫紉時間之兩倍。故, 此方法之效率不佳。除此之外,難以使第1縫合線及第2 縫合線形成一條疊在另一條之上,即難以在整個縫,初線上 φ 獲得均勻的縫合線強度。 三、發明內容 基於上述問題之考量,本發明之一個目的在提供一種縫 紉機,其可有效率且穩定地形成包含有完美縫線之獨立縫 合線及在同一線上包含有鉤住縫線的另一條獨立縫合線, 而縫合線具有足夠的強度。 本發明提供一種縫紉機,其中朝反時鐘或順時鐘方向轉 動之第1水平梭鉤、第1針、第2針、及與第1水平梭鉤 _ 同方向轉動之第2水平梭鉤被依序地配置,該縫紉機包括 有: 一個進給機構,其間歇地將待縫紉材料以第1及第2針 之間的距離相同之進給節距而進給,其中進給機構具有設 置於材料上方的上進給裝置(例如,在下列將解釋之實施例 中之一個上進給腳42),及設置在材料下方的下進給裝置 (例如,在該實施例中之下進給件34),並且夾在上進給裝 置與下進給裝置之間的材料係朝向配置梭鉤的方向而進 給;及 1296294 一個加壓裝置(例如,在該實施例中之 在形成每一針之時壓住材料。 在通常例子中,第1縫合線係由第1 所產生,而第2縫合線係由第2水平梭翁 並且每個獨立地產生之第1縫合線及第 一直線上。 在此情況下,一般,第1縫合線及第 括有完美縫線,而另一個則包含有鉤住 依照本發明縫紉機,其包含有完美縫 在同一線上包含有鉤住縫線的另一條獨 之縫合線,可以使用單一縫紉機朝單一 率地生產,即相同於傳統方式者。除此 立縫合線之進給節距可同步於另一條獨 距,因而’兩條獨JLL縫合線可均句地重 強且美觀的縫合線。除此之外,可在整 勻的縫合線強度。在縫紉機中,進給機 紉材料上方的上進給裝置及設置於材料 置;因而,很厚的材料可以很可靠地被 符合於均勻進給節距之美觀的縫合線。 四、實施方式 本發明之實施例將參照附圖而說明。 本發明縫紉機之第1實施例將參照第 第1圖顯示縫紉機之一般結構,其中 或構件之間的關係是以三維方式顯示。 近側(即操作員側)存在有操作員的空間 壓住腳5 3 ),其可 水平梭鉤及第1針 f及第2針所產生, 2縫合線形成在同 2縫合線之一個包 縫線。 線之獨立縫合線及 立縫合線的強度佳 方向而容易且有效 之外,其中一條獨 立縫合線的進給節 疊,因此產生一條 個縫合線上獲得均 構具有設置在待縫 下方的下進給裝 進給,並且可獲得 1至3圖而解釋。 縫紉機之主要元件 在此圖的觀看者之 。在下列解釋中’ 1296294 從操作員側看去時之位置關係是一般性的解釋。第2圖係 第1圖中之下方進給及梭鉤相關之元件或構件之放大圖。 第3圖係第丨圖中之上方進給相關之元件或構件之放大 圖。 第1圖之縫紉機具有朝反時鐘或順時鐘方向轉動之前水 平梭鉤15,一個前針2〇,一個後針21,及與梭鉤15同方 向轉動之一個後水平梭鉤1 6從操作員側依序地排成一直 線。一個設置於待進給材料下方的下進給件3 4、及一個設 • 置於待進給材料上方的上進給件42使材料從操作員側進 給到背側(即遠離操作員之側)。除此之外,設置有一個加 壓腳5 3,其可在每一針形成之時將待縫紉材料壓入。 一個驅動軸1可旋轉地被支持在縫紉機之臂中,並且一 個下軸5可旋轉地被支持在縫紉機之機床下方。驅動皮帶 輪2被固定到驅動軸丨之右端,並且動力從一個驅動馬達 (未顯示)到驅動皮帶輪2。一個計時皮帶4懸掛於驅動軸1 之計時皮帶輪3與下軸5之計時皮帶輪3之間,其可將驅 g 動軸1之轉動以1 : 1之傳動比傳遞到下軸5。 下面’將解釋使動力從從下軸5傳遞到前水平梭鉤1 5及 後水平梭鉤1 6之機構。 在縫紅ί機之機床下方,有一個鉤驅動傳動軸8係可轉動 且平行於下軸5而被支持,及一個鉤驅勸軸1 〇可轉動地被 支持著,其中鉤驅動軸1 0係垂直於鉤驅動傳動軸8。一條 鉤驅動計時皮帶7被懸掛於下軸5之鉤驅動計時皮帶輪6 與鉤驅動傳動軸8之鉤驅動計時皮帶輪6之間,因而可使 下軸5之轉動以1 : 1之傳動比而傳遞到鉤驅動傳動軸8。 1296294 鉤驅動傳動螺旋齒輪9被固定到每個鉤驅動傳動軸8及鉤 驅動軸1 〇。螺旋齒輪9之間的嚙合可使鉤驅動傳動軸8之 轉動以1 : 1之傳動比而傳遞到鉤驅動軸1 〇。 一個鉤驅動大螺旋齒輪1 1分別固定到鉤驅動軸1 〇之前 及後部。具有相似於習知水平梭鉤之結構的上述鉤驅動大 螺旋齒輪1 1、前水平梭鉤1 5及後水平梭鉤1 6被設置於對 應之前及後方位置上。一個鉤驅動小螺旋齒輪1 2被固定到 每個梭鉤之鉤軸13的下端,其中每個小螺旋齒輪12均與 φ 對應之鉤驅動大螺旋齒輪1 1嚙合,使鉤驅動軸1 0之轉動 以兩倍於原速度經由每個垂直於鉤驅動軸1 0之鉤軸1 3而 傳遞到前水平梭鉤1 5及後水平梭鉤1 6。 下面,將解釋使動力從下軸5傳遞到下進給件34(可從材 料下方進行使待縫紉材料之進給)之機構。 第1圖中以線狀顯示之水平進給凸輪22實際上爲偏心地 固緊到靠近下軸5之中心的圓盤。亦即,平行於凸輪之中 心軸且離開一個具體距離的凸輪22之轉動軸係與下軸5符 _ 合一致。做爲水平進給桿23之一端的輪構件可旋轉地配合 到水平進給凸輪22之周圍。水平進給桿23之另一端係可 旋轉地聯結到進給聯結連桿25之一端。在縫紉機之機床下 方,一個水平進給軸27係平行於下軸5而可旋轉地被支持 著。進給聯結連桿25之另一端可旋轉地聯結到固定於水平 進給軸27之水平進給驅動臂26。在水平進給桿23及進給 聯結連桿25之聯結部分上設置有一個進給控制檯24,其係 進給量控制機構(未顯示)之一個構成部。水平進給軸27之 轉動角可由改變進給控制檯2 4之角度而改變,並且此功能 -11- 1296294 係被用來使進給節距(進給待縫纟刃材料用)等於兩針20及2 1 之間的距離,因而使兩個縫合線在同一線上(即兩個縫合線 重疊)。依照上述之構造,下軸5之旋轉係可以往復運動之 具體量而經由水平進給凸輪22 '水平進給桿23、進給控制 檯24、進給聯結連桿25、水平進給驅動臂26而傳遞到水 平進給軸27。在此,每個下進給件34及上進給腳42之運 動的水平分量係由水平進給軸27之往復旋轉運動所提 供;但是,此將詳細解釋於下。 一個向上定位的水平進給臂28被固緊到水平進給軸27 # 之左端,並且進給檯30的一端可旋轉地聯結到水平進給臂 2 8之上端。在進給檯3 0之另一端形成有一個叉狀部分 30a 〇 在下軸5之左端固定省一個直立進給凸輪29,其在第1 圖中亦以線狀表示。但是,實際上進給凸輪29爲固定到下 軸5之偏心凸輪,其中凸輪係配合到進給檯3 0之叉狀部分 3 0a,而使凸輪可沿著叉狀部分之內側滑動。 齒部穿過針板1 4之上方而顯現(然後消失)的下進給件3 4 φ 被固定到進給桿3 1之上端。進給桿3 1之下端可旋轉地聯 結到進給檯30之叉狀部分30a之附近(即聯結到顯示於叉 狀部分之左側的突出部分)。除此之外,一個進給支持件32 可旋轉地周定到進給桿3 1,其中固定位置係靠近進給桿3 1 之中心。一個具有直立溝之進給桿檯3 3被固定到進給桿3 1 之附近的骨架。進給支持件32可沿著進給桿檯33之直立 溝而滑動。 下進給件34進行橢圓運動,其係由水平進給臂28所產 -12- 1296294 生之水平運動分量與由直立進給凸輪29產生之直立運動 分量所形成的合成體。 下面將解釋從水平進給軸27將動力傳遞到上進給腳 4 2 (以從待縫紉材料之上側進行衣服進給作業)及加壓腳 5 3 (以在每針被形成之時將待縫紉材料壓入)的機構。 在縫紉機之臂中,一個上進給搖軸3 8被設置成平行於驅 動軸1。除此之外,上進給驅動臂35及37分別被固定到水 平進給軸27及上進給搖軸3 8之右端。一個上進給聯結桿 φ 36之兩端分別可旋轉地聯結到上進給驅動臂35及37之自 由端。故,水平進給軸27之搖動被傳遞而成爲上進給搖軸 38之搖動。 在上進給搖軸3 8之左端固定有一個向下定位之上進給搖 臂39。在上進給搖臂39之下端固定有一個向左突出之元 件。該元件係配合到上進給搖檯40(下面將解釋)之凹部 40a,而使該元件可沿著凹部之內側滑動。上進給搖檯40 被固定到縫紉機之骨架,而使該檯之上端部可朝向前後方 _ 向搖動。在搖檯40之右側設置凹部40a,並且在搖橿40 之左側設置有一個環或直立孔,以引導上進給桿41 (下面將 解釋)。上進給桿4 1係配合穿過搖檯4 〇之環或直立孔,而 使桿可垂直地滑動通過環或直立孔,而上進給腳42被固定 到上進給桿4 1之下端,並且壓力經常地由上進給桿壓迫彈 簧43而從上側施加到桿4 1上。依照上述之構造,上進給 搖臂39之搖動操作可提供上進給腳42之水平運動分量, 而此搖動操作係根據上進給搖軸38之搖動角度而進行,該 角度係依照進給控制檯24之傾斜度而形成。 -13- 1296294 一個上進給凸輪44被固定到驅動軸1,其固定位置係靠 近驅動軸1之中心。上進給凸輪44在第1圖中亦以線狀表 示,但是,貫際上,凸輪44係偏心地固緊到驅動軸丨之圓 盤。亦即,平行於凸輪之中心軸且離開一個具體距離的凸 輪44之轉動軸係與第1圖之驅動軸」符合一致。做爲上進 給桿4 5之一端的輪構件係可旋轉地配合到水平進給凸輪 44之周圍。在縫紉機之臂中,一個上進給軸47係平行於驅 動軸1而可旋轉地被支持。在上進給軸47之右端固定有一 φ 個具有彎曲狹縫46a之上進給臂46,並且上進給軸47之左 端固定有一個上進給臂4 8,兩進給臂均垂直於驅動軸q。 上進給桿4 5之另一端可旋轉地啣接於上進給臂4 6之狹縫 4 6a中,其支持點係可調整,使上進給腳42及加壓腳53 之上升量可被控制。依照上述之結構,驅動軸1之旋轉可 以往復旋轉運動之具體量而被傳遞到上進給軸4 7。 上進給聯結連桿4 9之一端可旋轉地聯結到固緊於上進給 軸47的上進給臂48之自由端。一個l連桿50之一端可旋 g 轉地聯結到上進給聯結連桿49之另一端。在L連桿50之 角落(即彎曲部分)上形成有一個環部50a,其可旋轉地配合 到加壓桿52(將解釋如下)之凸部。加壓桿52被縫初機之骨 架所支持,而使加壓桿52可垂直地滑動,而壓力永遠由壓 力控制彈簧54從上側而被施加於桿上。在加壓桿52的下 端固定有加壓腳53,並且在加壓桿52的左側,設置有配合 到L連桿50之環部50a的上述凸部。上進給搖動連桿51 之一端可旋轉地聯結到L連桿5 0之另一端。上進給搖動連 桿5 1之另一端可旋轉地聯結到上進給桿4 1,其中聯結部分 -14- 1296294 係靠近桿4 1的上端。依照上述之構造時,可提供上進給腳 42及加壓腳53之垂直運動,這些垂直運動之方向(即朝向 上進給腳4 2及加壓腳5 3移動之方向)係彼此相反。故,上 進給腳42進行橢圓運動,其係由此垂直運動分量及上述水 平運動分量所形成的合成體。 第1實施例之縫紉機具有上述構造。下面將解釋此縫紉 機之縫紉操作。 首先,爲了將兩個產生的縫合線重疊,將進給控制檯24 φ 之傾斜度進行調整,使下進給件34及上進給腳42之水平 運動分量、即待縫紉材料之進給節距等於針之間的距離。 下面之縫紉操作將解釋如下。 驅動軸1依照驅動馬達(未顯示)之驅動操作而經由驅動 皮帶輪2旋轉,並且下軸5亦以1 ·· 1 (驅動軸1與下軸5之 間)之傳動比(即轉動比)經由計時皮帶輪3計時皮帶4而旋 轉。下軸5之旋轉經由鉤驅動計時皮帶輪6及鉤驅動計時 皮帶7而傳遞到鉤驅動傳動軸8,並進一步以1 : 1之傳動 _ 比經由鉤驅動傳動螺旋齒輪9而傳遞到鉤驅動軸1 〇。 鉤驅動軸1 0之旋轉經由鉤驅動大螺旋齒輪1丨及絢驅動 小螺旋齒輪1 2而傳遞到前後鉤軸1 3及分別固定到鉤軸1 3 的前水平梭鉤1 5及後水平梭鉤1 6,因而將梭鉤1 5及1 6 以兩倍於原來之速度而朝順時鐘或反時鐘方向旋轉。在此 過程中,針棒1 8根據驅動軸1之旋轉而由連桿機構(未顯 示)而直立地移動。依照上述之操作時,第1縫合線由固緊 到針棒1 8上之前針2 0與上述前水平梭鉤1 5之合作而被形 成,而第2縫合線則由後針2 1與和第1縫合線在同一線上 15 - 1296294 之上述後水平梭鉤1 6的合作而被形成。 當前水平梭鉤1 5及後水平梭鉤1 6朝順時鐘方向旋轉 時’第1縫合線包含有完美縫線,並且第2縫合線包含有 鉤住縫線’其中針線由於鉤與待縫紉材料之進給方向之間 的關係而絞纏在每個結上。當前水平梭鉤1 5及後水平梭鉤 1 6朝反時鐘方向旋轉時,第1縫合線包含有鉤住縫線,並 且第2縫合線包含有完美縫線。當然,在上述縫合線之形 成中’待縫紉材料係由下進給件34及上進給腳42所進給。 根據下軸5之轉動,水平進給凸輪22之旋轉係以具體旋 轉角度而以往復旋轉運動經由水平進給桿23、進給聯結連 桿25及水平進給驅動臂26傳遞到水平進給軸27。當水平 進給軸27以具體旋轉角度而進行往復旋轉運動之時,水平 進給臂28以具體旋轉角度而進行搖動。此搖動角度係由調 整進給控制檯24之傾斜度而決定,控制檯24係進給量控 制機構的一個構成要素。進給檯3 0根據水平進給臂2 8之 搖動而水平地移動(在此爲朝前後方向),並且此運動亦傳 遞到進給桿3 1之下端,因而經由進給支持件32而產生的 反方向之水平運動被傳遞到下進給件34。此下進給件34 之反方向的水平運動係爲將待縫紉材料進給之水平運動分 量之功能。 除此之外,由於下軸5之旋轉而使直立進給凸輪29之旋 轉,因而與凸輪29啣接的進給檯30之叉狀部分30a朝直 立方向移動,並且與進給檯30 —起移動的下進給件34亦 朝直立方向移動。此直立方向之移動係可做爲由下進給件 3 4而將待縫紉材料進給之用的垂直運動分量的功能。由於 -16- 1296294 此垂直運動分量及上述水平運動分量之合成,下進給件34 進行前後方向之橢圓運動(其中配置有梭鉤),使下進給件 34之齒部可交互地在針板上方出現且在板下方消失。 水平進給軸27之往復旋轉運動亦以往復旋轉運動方式經 由上進給驅動臂35、上進給聯結桿36及上進給驅動臂37 而傳遞到上進給搖軸3 8。根據此往復旋轉運動,上進給搖 臂3 9進行往復旋轉運動,並且上進給桿4 1及上進給腳42 經由上進給搖檯40而水平地移動(即在配置有梭鉤的前後 φ 方向上),其上端在前後方向上可旋轉地被支持。 由於上進給凸輪44根據驅動軸1之旋轉而轉動,上進給 軸47經由上進給桿45及上進給臂46而進行往復旋轉運 動,使上進給臂48進行往復旋轉運動。此運動經由上進給 聯結連桿49而傳遞到L連桿50。 當上進給臂48及上進給聯結連桿49朝向一個這些構件 遠離操作員的方向上搖動之時,L連桿50繞一個支持點而 朝反時鐘方向轉動,該支持點爲L連桿50與加壓桿52之 φ 聯結點。在此操作中,壓力係從壓力控制彈簧54施加在加 壓桿52上,並且加壓桿52之向下運動在加壓腳53接觸待 縫紉材料之時被限制。故,依照L連桿50之反時鐘方向轉 動時之轉動力,到上進給桿41之聯結點(從L連桿50)係沿 者反時鐘方向旋轉。從而,上進給桿41抵擋由上進給桿壓 迫彈簧43所施加的向下壓力時會上升,使固緊到上進給桿 4 1之上進給腳42會離開待縫紉材料而上升。此上升運動之 量係符合於上進給腳42之垂直運動分量。上進給腳42進 行前後方向上(其中配置有梭鉤)之橢圓運動,其係由該垂 -17- 1296294 直運動分量與上述水平運動分量之合成所產生。 待縫紉材料之實際進給操作係由下進給件34及上進給腳 4 2的合作所進行。亦即,當下進給件3 4沿著操作員側之橢

DESCRIPTION OF THE INVENTION 1. Field of the Invention The present invention relates to a sewing machine for forming a separate suture containing a perfect suture when the material to be sewn is fed in a single direction and Ask that the * line contains another separate suture that holds the suture. Second, prior art In the ball used in sports competitions, etc., each suture will be subjected to a high load, and the sewing thread will be slack and the suture will be split. The applicant of the present invention has proposed a method of producing a strong suture which comprises forming a separate suture comprising a perfect suture (i.e., a general suture) and comprising hooks on the same line (i.e., overlapping of the two sutures). Another independent suture of the suture (where the needle thread is twisted on each knot with the hook and loop). There is currently no special sewing machine for producing such strong sutures; however, the suture can be produced by using an existing sewing machine which can be modified or improved by a sewing method. For example, the suture described above can be produced by a sewing machine having a structure of a hook and a needle as shown in Fig. 5. In the sewing machine, the left horizontal hook 110, the left needle 102, the right needle 103, and the right horizontal hook 104 which rotates in the same direction as the hook 1 0 1 are arranged in a straight line toward the counterclockwise or clockwise direction. And the left needle 102 and the right needle 1〇3 are rocked in the direction A (perpendicular to the hook and in the direction of the alignment) to feed the material to be sewn. When the sewing machine is used, in order to form an independent suture containing a perfect suture and another independent suture including a suture on the same line, the feeding mechanism of the sewing machine is first removed to prohibit the needle from shaking. Then, sewing is performed while the material is manually moved toward the direction B (toward the direction indicated by one of the double arrows 1296294). The sewing action causes the hook 丨0丨 and the right horizontal hook 104 to rotate in the clockwise direction. When the material to be sewn is moved to the right (i.e., moved to the right of Fig. 5), the perfect stitch is generated by the left needle 102, and the hook stitch is generated by the right needle 103. When the material to be sewn is moved to the left, the perfect stitch is generated by the right needle 103, and the hook stitch is generated by the left needle 102. On the other hand, when the left horizontal hook 1 i and the right horizontal hook 104 rotate in the counterclockwise direction and the material to be sewn moves to the right, the perfect stitch is generated by the right needle 103, and the stitch is caught. φ is generated by the left needle 102. Conversely, when the material to be sewn is moved to the left and the hook 101 and the right horizontal hook 104 are rotated in the counterclockwise direction, the perfect stitch is generated by the left needle 102, and the hook is caught by the right needle! 03 produced. The method of forming the suture can also be carried out using a sewing machine shown in part (1) and part (2) of Fig. 6, which uses a horizontal hook and a vertical hook, respectively. Each sewing machine has a single hook 105 and a single needle 106, and the material to be sewn is fed perpendicular to the direction A-B (see the double arrow between the reference symbols A and B) in which the hook and the needle are disposed. In order to form a separate suture including a perfect suture and another independent suture including a suture on the same line by the above sewing machine, after the first suture is sewn toward the normal feeding direction A, the second suture The thread is sewn from the position X (i.e., the starting point of the first suture) or the position Y in the opposite direction B (i.e., the end of the first suture), so that the first suture and the second suture are formed on the same line. In this case, the first suture includes a perfect suture, and the second suture includes a hook suture. Among the separate sutures that form the perfect suture using the sewing machine of the fifth genus and the independent sutures that enclose the sutures of 1296294, the material to be sewn is fed by hand; thus, the pitch and direction of the sewing can be changed. And the strength of the suture can vary throughout the suture. In addition to this, work efficiency is reduced. Among the separate sutures that form the perfect suture and the separate sutures that hook the suture using the sewing machine of Fig. 6, the sewing system is performed in the general and opposite directions; therefore, the sewing time is two of the one-way sewing times. Times. Therefore, this method is not efficient. In addition to this, it is difficult to form the first suture and the second suture one on top of the other, that is, it is difficult to obtain uniform suture strength throughout the slit and the primary line φ. SUMMARY OF THE INVENTION Based on the above problems, it is an object of the present invention to provide a sewing machine which can efficiently and stably form a separate suture comprising a perfect suture and another strip containing a suture on the same line. Separate sutures, while sutures have sufficient strength. The present invention provides a sewing machine in which a first horizontal hook, a first needle, a second needle, and a second horizontal hook that rotates in the same direction as a first horizontal hook are rotated in a clockwise or clockwise direction. The sewing machine comprises: a feeding mechanism that intermittently feeds the material to be sewn at a feed pitch of the same distance between the first and second needles, wherein the feeding mechanism has a material disposed above the material Upper feed device (for example, one of the feed legs 42 in the embodiment to be explained below), and a lower feed device disposed below the material (for example, the lower feed member 34 in this embodiment) And the material sandwiched between the upper feeding device and the lower feeding device is fed in a direction in which the hook is disposed; and 1296294 a pressing device (for example, in the embodiment in which each needle is formed) In the normal example, the first suture is produced by the first one, and the second suture is composed of the second horizontal suspending and the first suture and the first straight line which are independently produced. In this case, in general, the first suture and the first one are perfect. a thread, and the other comprises hooking a sewing machine according to the invention, which comprises a separate seam comprising a perfect seam comprising hooked stitches on the same line, which can be produced in a single rate using a single sewing machine, ie the same In the traditional way, the feed pitch of the vertical suture can be synchronized with another single distance, so that the two independent JLL sutures can be uniformly and beautifully sutured. Uniform suture strength. In the sewing machine, the upper feeding device above the feeder material is placed on the material; thus, the thick material can be reliably matched to the uniform feeding pitch of the uniform feeding pitch. 4. Embodiments The present invention will be described with reference to the accompanying drawings. In the first embodiment of the sewing machine of the present invention, the general structure of the sewing machine will be described with reference to Fig. 1, wherein the relationship between the members is displayed in three dimensions. On the near side (ie, the operator side), there is an operator's space to press the foot 5 3 ), which can be generated by the horizontal hook and the first needle f and the second needle. 2 The suture is formed in one of the same 2 sutures. Suture . The independent stitching of the thread and the strength of the vertical suture are easy and effective, and the feeding of one independent suture is stacked, so that the sutures are obtained on one suture and the lower infeed is set under the suture to be sutured. The feed is loaded and can be explained by taking 1 to 3 figures. The main components of the sewing machine are the viewers of this figure. In the following explanation, the positional relationship when 1296294 is viewed from the operator side is a general explanation. Fig. 2 is an enlarged view of the components or members associated with the lower feed and the hook in Fig. 1. Figure 3 is an enlarged view of the components or components associated with the feed in the top of the figure. The sewing machine of Fig. 1 has a horizontal hook 15 before the counterclockwise or clockwise rotation, a front needle 2〇, a rear needle 21, and a rear horizontal hook 16 in the same direction as the hook 15 from the operator. The sides are arranged in a straight line in sequence. A lower feed member 34 disposed under the material to be fed, and an upper feed member 42 disposed above the material to be fed feed the material from the operator side to the back side (ie, away from the operator) side). In addition to this, there is provided a presser foot 53 which presses the material to be sewn at the time of formation of each needle. A drive shaft 1 is rotatably supported in the arm of the sewing machine, and a lower shaft 5 is rotatably supported under the machine tool of the sewing machine. The drive pulley 2 is fixed to the right end of the drive shaft , and the power is transmitted from a drive motor (not shown) to the drive pulley 2. A timing belt 4 is suspended between the timing pulley 3 of the drive shaft 1 and the timing pulley 3 of the lower shaft 5, which transmits the rotation of the drive shaft 1 to the lower shaft 5 at a gear ratio of 1:1. The mechanism for transmitting power from the lower shaft 5 to the front horizontal hook 15 and the rear horizontal hook 16 will be explained below. Below the machine tool of the sewing machine, a hook drive shaft 8 is rotatably supported parallel to the lower shaft 5, and a hook drive shaft 1 is rotatably supported, wherein the hook drive shaft 10 The drive shaft 8 is driven perpendicular to the hook. A hook driving timing belt 7 is suspended between the hook driving timing pulley 6 of the lower shaft 5 and the hook driving timing pulley 6 of the hook driving transmission shaft 8, so that the rotation of the lower shaft 5 can be transmitted with a transmission ratio of 1:1. The drive shaft 8 is driven to the hook. 1296294 A hook drive transmission helical gear 9 is fixed to each of the hook drive transmission shaft 8 and the hook drive shaft 1 。. The engagement between the helical gears 9 causes the rotation of the hook drive shaft 8 to be transmitted to the hook drive shaft 1 以 at a gear ratio of 1:1. A hook drive large helical gear 1 1 is fixed to the front and rear of the hook drive shaft 1 分别, respectively. The above-described hook-drive large helical gear 1 1 , front horizontal hook 15 and rear horizontal hook 16 having a structure similar to the conventional horizontal hook are disposed at positions before and after. A hook drive small helical gear 12 is fixed to the lower end of the hook shaft 13 of each hook, wherein each small helical gear 12 meshes with a hook-driven large helical gear 11 corresponding to φ, so that the hook drive shaft 10 The rotation is transmitted to the front horizontal hook 15 and the rear horizontal hook 16 via twice the hook axis 13 perpendicular to the hook drive shaft 10 at twice the original speed. Next, a mechanism for transferring power from the lower shaft 5 to the lower feed member 34 (which can feed the material to be sewn from below the material) will be explained. The horizontal feed cam 22, which is shown in a line in Fig. 1, is actually eccentrically fastened to the disc near the center of the lower shaft 5. That is, the rotational axis of the cam 22 parallel to the central axis of the cam and away from a specific distance coincides with the lower shaft 5. A wheel member as one end of the horizontal feed lever 23 is rotatably fitted around the horizontal feed cam 22. The other end of the horizontal feed lever 23 is rotatably coupled to one end of the feed coupling link 25. Below the machine tool of the sewing machine, a horizontal feed shaft 27 is rotatably supported parallel to the lower shaft 5. The other end of the feed coupling link 25 is rotatably coupled to the horizontal feed drive arm 26 fixed to the horizontal feed shaft 27. A feed console 24 is provided on the joint portion of the horizontal feed lever 23 and the feed coupling link 25, which is a constituent portion of a feed amount control mechanism (not shown). The angle of rotation of the horizontal feed axis 27 can be changed by changing the angle of the feed console 24, and this function -11- 1296294 is used to make the feed pitch (for feeding the material to be sewed) equal to two stitches. The distance between 20 and 2 1 thus causes the two sutures to be on the same line (ie, the two sutures overlap). According to the above configuration, the rotation of the lower shaft 5 can be reciprocated by a specific amount via the horizontal feed cam 22 'horizontal feed lever 23, the feed console 24, the feed coupling link 25, and the horizontal feed drive arm 26 It is transmitted to the horizontal feed axis 27. Here, the horizontal component of the motion of each of the lower feed member 34 and the upper feed member 42 is provided by the reciprocating rotational motion of the horizontal feed shaft 27; however, this will be explained in detail below. An upwardly positioned horizontal feed arm 28 is secured to the left end of the horizontal feed shaft 27#, and one end of the feed table 30 is rotatably coupled to the upper end of the horizontal feed arm 28. At the other end of the feed table 30, a fork portion 30a is formed. 直 An upright feed cam 29 is fixed at the left end of the lower shaft 5, which is also shown in a line in Fig. 1. However, actually, the feed cam 29 is an eccentric cam fixed to the lower shaft 5, wherein the cam is fitted to the fork portion 30a of the feed table 30, so that the cam can slide along the inner side of the fork portion. The lower feed member 3 4 φ which is formed (and then disappears) by the tooth portion passing over the needle plate 14 is fixed to the upper end of the feed lever 31. The lower end of the feed lever 3 1 is rotatably coupled to the vicinity of the fork portion 30a of the feed table 30 (i.e., coupled to the protruding portion displayed on the left side of the fork portion). In addition to this, a feed support member 32 is rotatably fixed to the feed rod 3 1, wherein the fixed position is near the center of the feed rod 3 1 . A feed bar 33 having an upright groove is fixed to the skeleton in the vicinity of the feed bar 3 1 . The feed support member 32 is slidable along the upright groove of the feed bar table 33. The lower feed member 34 performs an elliptical motion which is a composite formed by the horizontal motion component of the horizontal feed arm 28 and the vertical motion component produced by the upright feed cam 29. The transmission of power from the horizontal feed shaft 27 to the upper feed foot 4 2 (to carry out the clothes feeding operation from the upper side of the material to be sewn) and the pressurizing foot 5 3 (to be held when each needle is formed) will be explained below. The mechanism in which the sewing material is pressed in). In the arm of the sewing machine, an upper feed rocker 38 is disposed parallel to the drive shaft 1. In addition to this, the upper feed drive arms 35 and 37 are fixed to the right end of the horizontal feed shaft 27 and the upper feed rocker 38, respectively. Both ends of an upper feed link φ 36 are rotatably coupled to the free ends of the upper feed drive arms 35 and 37, respectively. Therefore, the shaking of the horizontal feed shaft 27 is transmitted to become the rocking of the upper feed rocker 38. At the left end of the upper feed rocker 38, a downwardly positioned upper feed rocker arm 39 is fixed. At the lower end of the upper feed rocker arm 39, a member projecting to the left is fixed. The element is fitted to the recess 40a of the upper feed cradle 40 (explained below) so that the element can slide along the inside of the recess. The upper feed cradle 40 is fixed to the skeleton of the sewing machine so that the upper end portion of the table can be swung toward the front and rear. A recess 40a is provided on the right side of the cradle 40, and a ring or upright hole is provided on the left side of the rocker 40 to guide the upper feed lever 41 (to be explained later). The upper feed rod 4 1 is fitted through a ring or upright hole of the cradle 4 so that the rod can slide vertically through the ring or the upright hole, and the upper feed leg 42 is fixed to the lower end of the upper feed rod 4 1 And the pressure is often applied to the rod 4 1 from the upper side by the upper feed rod pressing spring 43. According to the above configuration, the rocking operation of the upper feed rocker 39 can provide the horizontal motion component of the upper feed foot 42, and the rocking operation is performed according to the rocking angle of the upper feed rocker 38, which is in accordance with the feed. The inclination of the console 24 is formed. -13- 1296294 An upper feed cam 44 is fixed to the drive shaft 1 in a fixed position near the center of the drive shaft 1. The upper feed cam 44 is also shown in a line in Fig. 1, but in a continuous manner, the cam 44 is eccentrically fastened to the disc of the drive shaft. That is, the rotational axis of the cam 44 parallel to the central axis of the cam and away from a specific distance conforms to the drive shaft of Fig. 1. The wheel member as one end of the upper feed lever 45 is rotatably fitted around the horizontal feed cam 44. In the arm of the sewing machine, an upper feed shaft 47 is rotatably supported parallel to the drive shaft 1. At the right end of the upper feed shaft 47 is fixed a φ feed arm 46 having a curved slit 46a, and the left end of the upper feed shaft 47 is fixed with an upper feed arm 4 8, both of which are perpendicular to the drive Axis q. The other end of the upper feed rod 45 is rotatably coupled to the slit 46a of the upper feed arm 46, and the support point is adjustable, so that the upward amount of the upper feed leg 42 and the pressurizing foot 53 can be increased. controlled. According to the above configuration, the rotation of the drive shaft 1 can be transmitted to the upper feed shaft 47 in a specific amount of reciprocating rotational motion. One end of the upper feed coupling link 4.9 is rotatably coupled to the free end of the upper feed arm 48 that is fastened to the upper feed shaft 47. One end of a l link 50 is rotatably coupled to the other end of the upper feed link 49. At the corner (i.e., the curved portion) of the L link 50, a ring portion 50a is formed which is rotatably fitted to the convex portion of the pressurizing rod 52 (which will be explained below). The pressurizing rod 52 is supported by the skeleton of the sewing machine, so that the pressing rod 52 can slide vertically, and the pressure is always applied to the rod from the upper side by the pressure control spring 54. A pressurizing foot 53 is fixed to the lower end of the pressurizing rod 52, and the above-mentioned convex portion fitted to the ring portion 50a of the L link 50 is provided on the left side of the pressurizing rod 52. One end of the upper feed rocking link 51 is rotatably coupled to the other end of the L link 50. The other end of the upper feed rocker 5 1 is rotatably coupled to the upper feed rod 4 1, wherein the coupling portion -14 - 1296294 is adjacent to the upper end of the rod 4 1 . According to the above configuration, the vertical movement of the upper feed leg 42 and the pressurizing foot 53 can be provided, and the direction of these vertical movements (i.e., the direction in which the upper feed leg 42 and the pressurizing leg 53 move) are opposite to each other. Therefore, the upper feed leg 42 performs an elliptical motion which is a composite formed by the vertical motion component and the above horizontal motion component. The sewing machine of the first embodiment has the above configuration. The sewing operation of this sewing machine will be explained below. First, in order to overlap the two produced sutures, the inclination of the feed console 24φ is adjusted so that the horizontal motion component of the lower feed member 34 and the upper feed leg 42, that is, the feed section of the material to be sewn The distance is equal to the distance between the needles. The sewing operation below will be explained as follows. The drive shaft 1 is rotated via the drive pulley 2 in accordance with a drive operation of a drive motor (not shown), and the lower shaft 5 is also transmitted at a gear ratio (i.e., a rotation ratio) of 1··1 (between the drive shaft 1 and the lower shaft 5). The timing pulley 3 rotates the timing belt 4. The rotation of the lower shaft 5 is transmitted to the hook drive transmission shaft 8 via the hook drive timing pulley 6 and the hook drive timing belt 7, and is further transmitted to the hook drive shaft 1 by a 1:1 drive ratio than via the hook drive transmission helical gear 9. Hey. The rotation of the hook drive shaft 10 is transmitted to the front and rear hook shafts 13 via the hook drive large helical gear 1丨 and the cymbal drive small helical gear 12, and the front horizontal hooks 15 and the rear horizontal shuttle respectively fixed to the hook shafts 13. The hooks 1 6 thus rotate the hooks 15 and 16 in a clockwise or counterclockwise direction at twice the original speed. During this process, the needle bar 18 is moved upright by a link mechanism (not shown) in accordance with the rotation of the drive shaft 1. According to the above operation, the first suture is formed by the cooperation of the front needle 20 and the front horizontal hook 15 on the needle bar 18, and the second stitch is formed by the rear needle 2 1 and The first suture is formed by the cooperation of the above-described rear horizontal hooks 16 on the same line 15 - 1296294. When the current horizontal hook 15 and the rear horizontal hook 16 are rotated in the clockwise direction, 'the first stitch contains the perfect stitch, and the second stitch contains the hooked stitch' where the needle thread is due to the hook and the material to be sewn The relationship between the feed directions is twisted on each knot. When the current horizontal hook 15 and the rear horizontal hook 16 are rotated in the counterclockwise direction, the first suture includes hooked sutures, and the second suture includes perfect sutures. Of course, in the formation of the suture described above, the material to be sewn is fed by the lower feed member 34 and the upper feed member 42. According to the rotation of the lower shaft 5, the rotation of the horizontal feed cam 22 is transmitted to the horizontal feed shaft via the horizontal feed lever 23, the feed coupling link 25, and the horizontal feed drive arm 26 in a reciprocating rotational motion at a specific rotation angle. 27. When the horizontal feed shaft 27 performs a reciprocating rotational motion at a specific rotation angle, the horizontal feed arm 28 is rocked at a specific rotation angle. This rocking angle is determined by adjusting the inclination of the feed console 24, which is a component of the feed amount control mechanism. The feed table 30 is horizontally moved (here, in the front-rear direction) according to the shaking of the horizontal feed arm 28, and this movement is also transmitted to the lower end of the feed lever 31, and thus is generated via the feed support 32. The horizontal movement in the opposite direction is transmitted to the lower feed member 34. The horizontal movement in the opposite direction of the lower feed member 34 is a function of the horizontal motion component for feeding the material to be sewn. In addition to this, the rotation of the upright feed cam 29 is caused by the rotation of the lower shaft 5, so that the fork portion 30a of the feed table 30 engaged with the cam 29 moves in the upright direction and starts with the feed table 30. The moving lower feed member 34 also moves in the upright direction. This movement in the upright direction can be used as a function of the vertical motion component for feeding the material to be sewn by the lower feed member 34. Due to the combination of the vertical motion component of the-16-1296294 and the horizontal motion component described above, the lower feed member 34 performs an elliptical motion in the front-rear direction (in which the hook is disposed), so that the teeth of the lower feed member 34 can be alternately placed on the needle. Appears above the board and disappears below the board. The reciprocating rotational motion of the horizontal feed shaft 27 is also transmitted to the upper feed rocker 38 via the upper feed drive arm 35, the upper feed link 36 and the upper feed drive arm 37 in a reciprocating rotational motion. According to this reciprocating rotational motion, the upper feed rocker 39 performs a reciprocating rotational motion, and the upper feed rod 41 and the upper feed leg 42 are horizontally moved via the upper feed cradle 40 (i.e., in the configuration of the hook In the front and rear φ directions, the upper end is rotatably supported in the front and rear direction. Since the upper feed cam 44 rotates in accordance with the rotation of the drive shaft 1, the upper feed shaft 47 reciprocates by the upper feed lever 45 and the upper feed arm 46, and the upper feed arm 48 reciprocates. This movement is transmitted to the L link 50 via the upper feed coupling link 49. When the upper feed arm 48 and the upper feed coupling link 49 are rocked in a direction away from the operator, the L link 50 rotates in a counterclockwise direction about a support point which is an L link. 50 is connected to the φ of the pressing rod 52. In this operation, a pressure system is applied from the pressure control spring 54 to the pressing rod 52, and the downward movement of the pressing rod 52 is restricted when the pressing leg 53 contacts the material to be sewn. Therefore, in accordance with the rotational force when the L-link 50 is rotated in the counterclockwise direction, the coupling point to the upper feed lever 41 (from the L link 50) is rotated in the counterclockwise direction. Therefore, the upper feed lever 41 rises when it is pressed against the downward pressure applied by the upper feed lever pressing spring 43, so that the feed leg 42 is lifted away from the material to be sewn by being fastened to the upper feed lever 41. This amount of ascending motion is in accordance with the vertical motion component of the upper feed foot 42. The upper feed leg 42 performs an elliptical motion in the front-rear direction (in which the hook is disposed), which is produced by the combination of the vertical motion component of the vertical -17-1296294 and the horizontal motion component described above. The actual feeding operation of the material to be sewn is performed by the cooperation of the lower feed member 34 and the upper feed member 42. That is, when the lower feed member 34 is synchronized along the elliptical trajectory of the operator side, the upper feed foot 42 is lowered along the elliptical trajectory of the operator side, thereby sandwiching the material to be sewn. Between the member 34 and the upper feed leg 42. In this state (i.e., the material is sandwiched between the lower feed member 34 and the upper feed leg 42), the lower feed member 34 and the upper feed leg 42 are removed from the operator. When the two members reach the rear end of the elliptical trajectory, the lower feed member φ 34 is lowered and the upper feed leg 42 is raised. The two components are then moved again to the operator. _ This series of movements is repeated' thus intermittently feeding the material to be sewn away from the operator. When the upper feed arm 48 and the upper feed coupling link 4 are rocked toward one of the members toward the operator, the L link 50 rotates clockwise around a support point, the support point being The junction of the L link 50 and the pressurizing rod 52. In this operation, the pressure is applied to the upper feed rod 4 1 from the upper feed rod pressing spring 4 3 , and the downward movement of the upper feed rod 4 1 is in the upper feed _ the feed foot 42 contacts the material to be sewn. Time is limited. Therefore, according to the rotational force when the L link 50 is rotated in the clockwise direction, the coupling point (from the L_rod 50) to the pressurizing lever 52 is rotated in the clockwise direction. Therefore, the pressing lever 52 rises when it is pressed against the downward pressure applied by the pressure control spring 54, so that the pressing leg 53 fastened to the pressing lever 52 rises away from the material to be sewn. The movement of the pressurizing foot 53 is synchronized with the timing of the feed member 34 and the upper feed leg 42 from the operator to be gripped between the materials to be sewn to feed the material. Therefore, the pressurizing foot 53 never hinders the operation of feeding the material to be sewn. On the other hand, when the upper feed foot 42 is raised and is away from the material to be sewn, the pressurizing foot 53 is lowered to clamp the material to be sewn to -18 - 1296294, thereby assisting in forming the stitch (needle) at the needles 20 and 21 . As explained above, according to (1) the formation of the first horizontal hook 15 and the front needle 20 by the first suture, (ii) the formation of the horizontal hook 16 and the rear needle 21 after the second suture is used, and (iii) The material to be sewn is transferred toward the rear of the configuration hook, the elliptical motion of the lower feed member 34 and the upper feed leg 42 or the vertical movement of the upper feed leg 42 and the pressurizing foot 53 is to be sewn. The material may be intermittently fed at a feed pitch equal to the distance between the needles 20 and 21, such that a separate suture containing the perfect suture and another separate suture containing the hook suture are formed On the same line. Next, a second embodiment of the sewing machine of the present invention will be explained with reference to Fig. 4. The basic structure of the sewing machine of this embodiment is the same as that of the first embodiment. Therefore, elements or members having the same function are given the same symbols, and only the different features are explained. In this sewing machine, a horizontal shuttle 15, which rotates in a counterclockwise or clockwise direction, a needle 20, a needle 21, and horizontal hooks 16 which are rotated in the same direction as the horizontal hook 15 are sequentially arranged. A lower feed mechanism (including the upper feed foot 4 2, etc.) feeding the material to be fed at a feed pitch equal to the distance between the needles 20 and 21 is disposed below the material to be fed, and The upper feed mechanism (including the upper feed rod 41, the upper feed foot 42, and the like) is disposed above the material to be fed. There is also provided a garment pressurizing device for compressing the material to be fed when the suture is formed (including the pressurizing rod 52, the pressurizing foot 53, etc.). The sewing machine of the present embodiment is characterized in that the horizontal hook 15', the needle 21, the needle 21, and the hook arrangement direction of the horizontal hook 16 are disposed, and the feeding direction of the material to be sewed is the same as that of the first embodiment. Change 9 degrees when comparing. Also, in the sewing machine of the first embodiment, the arrangement direction of the hook and the feeding direction of the material to be sewn are perpendicular to the direction of the arm 6 (i.e., the drive shaft 1). However, in the sewing machine of the second embodiment, the arrangement direction of the hooks and the feeding direction of the material to be sewn are parallel to the direction of the arm 60 (i.e., the drive shaft 1). Therefore, in the second embodiment, the operator position is on the free end side of the arm (i.e., on the left side of Fig. 4), and the material to be sewn is toward the wall 6 1 of the sewing machine or from the wall 6 1 (see Fig. 4). ) Feed. In the sewing machine having such a configuration, the individual sutures of the perfect suture and the individual sutures which are hooked to the suture can be formed on the same line as the first embodiment. The invention is not limited to the embodiments described above, and modifications and changes are possible within the scope and spirit of the invention.
