Description

縫線供給裝置 Suture supply device

本發明是有關於一種縫紉機，特別是指一種縫線供給裝置。 The present invention relates to a sewing machine, in particular to a sewing thread supply device.

一種如台灣專利號數第I489021號專利所公開的縫紉機之下線供給裝置，包含一帶動上線穿過布料且上下移動的針桿1、一配合該針桿1移動而同步水平旋轉的外釜、一設置於該外釜內而不與該外釜同步旋轉的內釜2，及一設置於該內釜2內的下線捲軸。該外釜會捕捉穿設於該針桿1的上線，並帶動該上線繞過由該下線捲軸所拉出的下線，使得該上線與該下線彼此纏繞並縫製於布料。如此一來，便可以將布料沿著一縫製方向推送至該針桿1下方以完成縫製。又，市面上所販售縫紉機中，該針桿1的下針位置可以沿著一垂直於該縫製方向的左右方向D2進行調整，從而可以在只沿著該縫製方向推送布料的狀況下，縫製出具備寬度變化的圖樣。 A lower thread supply device for a sewing machine as disclosed in Taiwan Patent No. I489021, comprising a needle bar 1 that drives the upper thread to pass through the cloth and moves up and down, an outer kettle that rotates synchronously and horizontally with the movement of the needle bar 1, a The inner kettle 2 is arranged in the outer kettle and does not rotate synchronously with the outer kettle, and a down-line reel is arranged in the inner kettle 2. The outer kettle catches the upper thread running through the needle bar 1 and drives the upper thread to bypass the lower thread pulled by the lower thread reel, so that the upper thread and the lower thread are wound around each other and sewed to the fabric. In this way, the fabric can be pushed under the needle bar 1 along a sewing direction to complete the sewing. In addition, in the sewing machines sold in the market, the needle lowering position of the needle bar 1 can be adjusted along a left-right direction D2 perpendicular to the sewing direction, so that the sewing machine can be sewn under the condition that the fabric is only pushed along the sewing direction. A pattern with varying widths is produced.

然而，由於該下線供給裝置所應用的內釜2是屬於水平式的內釜，下針位置的變動容易導致所縫製出的圖樣的收線效果不均一。參閱圖1，一上線91與一下線92沿著一縫製方向X被縫製在一 布料93上。其中，該上線91收線時會形成複數線輪911。在圖1中，在左側進行收線時所產生的線輪911顯然比在右側進行收線時所產生的線輪911大，便是前述『收線效果不均一』的具體例示。因此，如何產生均勻收線的效果遂成為一項值得探討的議題。 However, since the inner kettle 2 used in the lower thread supply device is a horizontal inner kettle, the variation of the position of the lower needle easily leads to the uneven thread take-up effect of the sewn pattern. Referring to FIG. 1, an upper thread 91 and a lower thread 92 are sewn along a sewing direction X on a on fabric 93. Wherein, when the upper wire 91 takes up the wire, a plurality of wire pulleys 911 will be formed. In FIG. 1 , the reel 911 produced when the wire is taken up on the left side is obviously larger than the reel 911 produced when the wire is taken up on the right side, which is a specific example of the above-mentioned “ununiform wire take-up effect”. Therefore, how to produce the effect of uniform winding has become a topic worthy of discussion.

因此，本發明的目的，即在提供一種具備均勻收線效果的縫線供給裝置。 Therefore, the object of the present invention is to provide a suture supply device with a uniform thread take-up effect.

於是，本發明縫線供給裝置，適用於將一上線與一下線縫製在一布料，該下線由一線軸供給。該縫線供給裝置包含一針桿，及一內釜。 Therefore, the sewing thread supply device of the present invention is suitable for sewing an upper thread and a lower thread into a cloth, and the lower thread is supplied by a spool. The suture supply device includes a needle bar and an inner kettle.

該針桿用以帶動該上線穿過該布料。該針桿可被驅動而沿一上下方向在一上針位置與一下針位置之間移動，且可沿一垂直於該上下方向的左右方向在一左基位置與一右基位置之間移動。定義一同時垂直於該上下方向與該左右方向的前後方向，及一垂直於該上下方向且沿該前後方向延伸的假想面。該假想面包括一沿該前後方向延伸且通過該左基位置的左邊界線，及一該前後方向延伸且通過該右基位置的右邊界線。 The needle bar is used to drive the upper thread to pass through the fabric. The needle bar can be driven to move in an up-down direction between a needle-up position and a needle-down position, and can move in a left-right direction perpendicular to the up-down direction between a left base position and a right base position. Define a front-rear direction perpendicular to both the up-down direction and the left-right direction, and an imaginary plane perpendicular to the up-down direction and extending along the front-rear direction. The imaginary surface includes a left boundary line extending in the front-rear direction and passing through the left base position, and a right boundary line extending in the front-rear direction and passing through the right base position.

該內釜設置於該布料下方，並包括一內釜基壁、一環繞於該內釜基壁的內釜周壁，及一設置於該內釜周壁的出線單元。該內釜基壁與該內釜周壁界定出一開口朝上的容置空間。 The inner kettle is arranged below the cloth, and includes an inner kettle base wall, an inner kettle peripheral wall surrounding the inner kettle base wall, and a wire outlet unit arranged on the inner kettle peripheral wall. The inner kettle base wall and the inner kettle peripheral wall define an accommodating space with an opening facing upward.

該線軸設置於該容置空間並用以供給該下線。該下線會由該線軸出發並在經過該出線單元後抵達該布料。當該下線經過該出線單元時，該下線會靠抵於該出線單元。定義該下線靠抵於該出線單元的位置為一出線點，該出線單元可界定出至少一出線點。該至少一出線點可界定出一最終出線點。該最終出線點沿該上下方向投影於該假想面時位於該左邊界線與該右邊界線之間。 The bobbin is disposed in the accommodating space and used for supplying the lower thread. The lower thread will start from the spool and reach the fabric after passing through the thread outlet unit. When the lower wire passes through the outlet unit, the lower wire will abut against the outlet unit. A position where the lower line abuts against the outgoing line unit is defined as an outgoing line point, and the outgoing line unit can define at least one outgoing line point. The at least one outlet point may define a final outlet point. The final line exit point is located between the left boundary line and the right boundary line when projected on the imaginary surface along the up-down direction.

本發明的功效在於：藉由該最終出線點沿該上下方向投影於該假想面時位於該左邊界線與該右邊界線之間，該上線與該下線彼此纏繞而收線時會產生均勻收線的效果。 The effect of the present invention is: when the final wire outlet point is projected on the imaginary surface along the upper and lower directions, it is located between the left boundary line and the right boundary line, the upper line and the lower line are intertwined with each other and the wire will be drawn evenly when the wire is retracted Effect.

The imaginary plane A includes a left boundary line BL extending in the front-rear direction D3 and passing through the left base position, and a right boundary line BR extending in the front-rear direction D3 and passing through the right base position. It should be noted that the left base position in the first embodiment refers to the position where the needle bar 1 moves to the leftmost position, and the right base position refers to the position where the needle bar 1 moves to the rightmost position.

參閱圖2、圖4與圖5，該內釜2設置於該布料下方，並包 括一內釜基壁21、一環繞於該內釜基壁21的內釜周壁22，及一設置於該內釜周壁22的出線單元23。該內釜基壁21與該內釜周壁22界定出一開口朝上的容置空間P。 Referring to Fig. 2, Fig. 4 and Fig. 5, the inner kettle 2 is arranged under the cloth and wraps It includes an inner kettle base wall 21 , an inner kettle peripheral wall 22 surrounding the inner kettle base wall 21 , and an outlet unit 23 arranged on the inner kettle peripheral wall 22 . The inner pot base wall 21 and the inner pot peripheral wall 22 define an accommodating space P with an opening facing upward.

該出線單元23包括一設置於該內釜周壁22的內側的固定片24，及一設置於該內釜周壁22與該固定片24之間的彈性片25。該固定片24包括一固定於該內釜周壁22的固定部241、一連接於該固定部241且與該內釜周壁22相間隔的出線部242、一設置在該出線部242且由內側貫通至外側的線孔243、一凹設於該出線部242上緣且與該線孔243互不連通的線槽244，及一凹設於該固定部241上緣且延伸至該出線部242而與該線孔243彼此連通的導槽245(參閱圖6)。由上方觀察該內釜2時，該固定片24的該出線部242設置在該固定部241的逆時針方向。該彈性片25具有一固定於該固定部241的固定端251，及一同時與該內釜周壁22和該出線部242相間隔的懸浮端252。 The outlet unit 23 includes a fixing piece 24 disposed on the inner side of the inner tank peripheral wall 22 , and an elastic piece 25 disposed between the inner tank peripheral wall 22 and the fixing piece 24 . The fixing piece 24 includes a fixing portion 241 fixed to the inner pot peripheral wall 22 , a wire outlet portion 242 connected to the fixing portion 241 and spaced from the inner pot peripheral wall 22 , a wire outlet portion 242 disposed on the wire outlet portion 242 and formed by A wire hole 243 extending from the inside to the outside, a wire groove 244 recessed on the upper edge of the wire outlet portion 242 and not communicating with the wire hole 243, and a wire groove 244 recessed on the upper edge of the fixing portion 241 and extending to the outlet The wire portion 242 and the wire hole 243 communicate with each other in a guide groove 245 (see FIG. 6 ). When viewing the inner kettle 2 from above, the wire outlet portion 242 of the fixing piece 24 is disposed in the counterclockwise direction of the fixing portion 241 . The elastic sheet 25 has a fixed end 251 fixed to the fixed portion 241 , and a floating end 252 spaced from the inner kettle peripheral wall 22 and the wire outlet portion 242 at the same time.

該線軸84設置於該容置空間P並用以供給該下線82。該下線82會由該線軸84出發並在經過該出線單元23後抵達該布料83。具體來說，將該線軸84安裝於該容置空間P時，該下線82會由該線軸84出發並被該導槽245引導至該線孔243，使得該下線82穿過該線孔243。該下線82穿過該線孔243後，使用者應將該下線82引導至該線槽244，使得該下線82靠抵於該線槽244內。此時，該 下線82由該線孔243延伸至該線槽244的部分會被該懸浮端252與該出線部242共同夾持，使得該下線82保持適當的張力。 The spool 84 is disposed in the accommodating space P and used to supply the lower wire 82 . The lower thread 82 will start from the spool 84 and reach the cloth 83 after passing through the thread outlet unit 23 . Specifically, when the spool 84 is installed in the accommodating space P, the lower thread 82 will start from the spool 84 and be guided to the thread hole 243 by the guide groove 245 , so that the lower thread 82 passes through the thread hole 243 . After the lower thread 82 passes through the thread hole 243 , the user should guide the lower thread 82 to the thread groove 244 so that the lower thread 82 abuts in the thread groove 244 . At this time, the The portion of the lower wire 82 extending from the wire hole 243 to the wire groove 244 will be jointly clamped by the floating end 252 and the wire outlet portion 242 , so that the lower wire 82 maintains a proper tension.

當該下線82經過該出線單元23時，該下線82會靠抵於該出線單元23。定義該下線82靠抵於該出線單元23的位置為一出線點E。要說明的是，在本第一實施例中，該出線單元23只界定出一位於該線槽244的出線點E，且該下線82經過該出線點E之後並不會再靠抵於該出線單元23的其他部位。因此，在本第一實施例中該出線點E即為最終出線點F，且該最終出線點F沿該上下方向D1投影於該假想面A時位於該左邊界線BL與該右邊界線BR之間。此外，在本第一實施例中該最終出線點F與該左邊界線BL之間的距離和該最終出線點F與該右邊界線BR之間的距離相同。 When the lower wire 82 passes the outlet unit 23 , the lower wire 82 abuts against the outlet unit 23 . An outlet point E is defined where the lower wire 82 abuts against the outlet unit 23 . It should be noted that, in the first embodiment, the wire outlet unit 23 only defines a wire outlet point E located in the wire slot 244 , and the lower wire 82 will not abut against the wire outlet point E after passing through the wire outlet point E. at other parts of the outlet unit 23 . Therefore, in the first embodiment, the outlet point E is the final outlet point F, and the final outlet point F is located on the left boundary line BL and the right boundary line when projected on the imaginary plane A along the up-down direction D1 between BRs. In addition, in the first embodiment, the distance between the final outlet point F and the left boundary line BL is the same as the distance between the final outlet point F and the right boundary line BR.

然而此處只為舉例而言，在其他的變化例子中，該出線單元23也可以界定出兩個、三個或四個以上的出線點E。在具有多個出線點E的例子中，應依據該下線82經過的順序進行判斷，將該下線82抵達該布料前最後經過的出線點E視為該最終出線點F。要特別強調的是，只有該最終出線點F以『沿該上下方向D1投影於該假想面A時位於該左邊界線BL與該右邊界線BR之間』為必要限制，其餘出線點E不應以此為限。 However, this is only an example, in other variation examples, the outlet unit 23 may also define two, three or more than four outlet points E. In an example with multiple outlet points E, judgment should be made according to the order in which the lower thread 82 passes, and the outlet point E that the lower thread 82 passes through last before reaching the cloth is regarded as the final outlet point F. It should be emphasized that only the final outlet point F is limited to "being located between the left boundary line BL and the right boundary line BR when projected on the imaginary plane A along the up-down direction D1", and the other outlet points E are not This should be the limit.

該上線81與該下線82彼此纏繞而收線時，該下線82會被收束至該針桿1處。此時，該最終出線點F與該針桿1之間的相對位 置關係便決定了該上線81與該下線82的收線角度。以圖4為例，本第一實施例的該針桿1在該左基位置時可界定出一第一收線角度S1，本第一實施例的該針桿1在該右基位置時可界定出一第二收線角度S2。由於該最終出線點F與該左邊界線BL之間的距離和該最終出線點F與該右邊界線BR之間的距離相同，該第一收線角度S1與該第二收線角度S2也會相同。如此一來，該上線81所產生的線輪會被限制在一定的誤差範圍之內，本第一實施例便能產生均勻化的收線效果。具體的收線效果可參閱圖7，該上線81收線時會形成複數線輪811，比較『在左側進行收線時所產生的線輪811』與『在右側進行收線時所產生的線輪811』可以發現尺寸較為均一而有別於先前技術中收線效果不均一的狀況。 When the upper thread 81 and the lower thread 82 are wound around each other to take up the thread, the lower thread 82 will be retracted to the needle bar 1 . At this time, the relative position between the final thread outlet point F and the needle bar 1 The setting relationship determines the take-up angle of the upper line 81 and the lower line 82 . Taking FIG. 4 as an example, the needle bar 1 of the first embodiment can define a first take-up angle S1 when the needle bar 1 is at the left base position, and the needle bar 1 of the first embodiment can be at the right base position. A second take-up angle S2 is defined. Since the distance between the final outlet point F and the left boundary line BL is the same as the distance between the final outlet point F and the right boundary line BR, the first retraction angle S1 and the second retraction angle S2 are also will be the same. In this way, the wire wheel generated by the upper wire 81 will be limited within a certain error range, and the first embodiment can produce a uniform wire take-up effect. The specific thread reeling effect can be seen in FIG. 7 , when the upper thread 81 is reeled, a plurality of reels 811 will be formed. The size of the wheel 811 ″ can be found to be relatively uniform, which is different from the situation in which the wire take-up effect is not uniform in the prior art.

還要說明的是，雖然『該最終出線點F與該左邊界線BL之間的距離和該最終出線點F與該右邊界線BR之間的距離相同』的限制條件可以使得本第一實施例在收線時具備最佳的均勻化效果，但是在其他的變化例子中即使該最終出線點F與該左邊界線BL之間的距離和該最終出線點F與該右邊界線BR之間的距離不同，只要有『該最終出線點F被限制於該左邊界線BL與該右邊界線BR之間』的限制條件存在，仍能產生一定程度的均勻化效果。因此，實施本案技術時不應以『該最終出線點F與該左邊界線BL之間的距離和該最終出線點F與該右邊界線BR之間的距離相同』為必要的限制 條件。 It should also be noted that although the limitation of "the distance between the final outlet point F and the left boundary line BL is the same as the distance between the final outlet point F and the right boundary line BR" can make this first implementation For example, it has the best homogenization effect when reeling, but in other variation examples, even if the distance between the final outlet point F and the left boundary line BL and the distance between the final outlet point F and the right boundary line BR With different distances, as long as there is a restriction condition that "the final exit point F is limited between the left boundary line BL and the right boundary line BR", a certain degree of homogenization effect can still be produced. Therefore, when implementing the technique of this case, "the distance between the final outlet point F and the left boundary line BL is the same as the distance between the final outlet point F and the right boundary line BR" as a necessary restriction condition.

參閱圖8與圖9，本發明縫線供給裝置的一第二實施例類似於該第一實施例，其差異之處在於：由上方觀察該內釜2時，該固定片24的該出線部242設置在該固定部241的順時針方向。 Referring to FIGS. 8 and 9 , a second embodiment of the suture supply device of the present invention is similar to the first embodiment, with the difference that: when the inner kettle 2 is viewed from above, the thread outlet of the fixing piece 24 The portion 242 is provided in the clockwise direction of the fixing portion 241 .
