使用鎖縫原理縫製的縫紉機時，不論是使用全迴轉的旋梭或是半迴轉的擺梭都會具有能捲繞底線的梭芯，並且，運用鎖縫原理縫製的縫紉機大部分都具有能容納梭芯的梭殼。When sewing machines that use the principle of lock stitching, whether they use a full-turn shuttle or a half-turn shuttle, they will have a bobbin that can wind the bottom thread. Moreover, most sewing machines that use the principle of lock stitching can accommodate the shuttle. The core of the bobbin case.

然而，為了提高縫紉機的轉速，所以梭芯容置底線的容量不能過多，相對就會限制底線的長度，致使必須時常更換梭芯以避免底線耗盡，並且，當更換底線作業時，不僅縫紉機必須停止車縫作業，甚至操作人員還必須手動更換底線，相對無法提高生產效能。However, in order to increase the speed of the sewing machine, the capacity of the bobbin to accommodate the bottom thread should not be too much, which will limit the length of the bottom thread.

After the first clamping jaw assembly 23 and the second clamping jaw assembly 24 do not clamp the bobbin set 50, the bottom thread 60 remaining in the first bobbin set 501 is removed. The third driving source 3131 of the three movement assembly 313 drives the third transmission member 3132 of the third movement assembly 313 to move along the movement axis L, so that the synchronization protrusion 3142 of the synchronization assembly 314 moves toward the end of the synchronization groove 3141. The moving third transmission member 3132 can drive the bobbin case 52 of the first bobbin set 501 to be axially separated from the bobbin 51 of the first bobbin set 501, so that the bobbin case 52 of the first bobbin set 501 is The two bobbins 51 of the bobbin set 501 are in a separated state S1 separated from each other.

請參閱圖15B所示，接下來，切線機構42的切線驅動源421帶動切線機構42的切刀422進行轉動，而抽吸機構43開始進行運轉以形成吸引氣流A，隨後，活動機構41的活動驅動源411帶動活動機構41的活動臂412進行擺動，使切線驅動源421、切刀422與抽吸機構43三者同步進行向下擺動，進而使進行轉動的切刀422移動至一切斷位置C以切斷位在捲繞空間513內部剩餘的底線60，而當位在捲繞空間513內部的底線60被切刀422切斷時，抽吸機構43的抽吸口431會位在梭芯51的側邊，使得抽吸機構43的吸引氣流A能除去被切刀422切斷的底線60，如圖所示，由於對位機構44能將限制第一梭芯組501的穿設空間514要位在捲線軸件511的正上方，進而當切刀422位於切斷位置C時，穿設空間514透過對位機構44能對齊於位在切斷位置C的切刀422，使切刀422不但能穿入穿設空間514以確保切刀422能確實切斷底線60，還能確保不會干涉到捲線軸件511，接下來，活動機構41的活動驅動源411帶動活動機構41的活動臂412向上擺動，使切線驅動源421、切刀422與抽吸機構43三者遠離梭芯51，其中，當切刀422剛脫離梭芯51的穿設空間514時，第一運動組件311的第一傳動件3112即可帶動梭芯51進行轉動以增進抽吸機構43吸除剩餘底線60的效果，使第一梭芯組501的梭芯51呈現一未捲繞底線60的初始狀態S2即完成清除底線60的作業。Please refer to FIG. 15B. Next, the thread cutting drive source 421 of the thread cutting mechanism 42 drives the cutting knife 422 of the thread cutting mechanism 42 to rotate, and the suction mechanism 43 starts to operate to form a suction airflow A. Then, the movement of the movable mechanism 41 The driving source 411 drives the movable arm 412 of the movable mechanism 41 to swing, so that the thread cutting driving source 421, the cutter 422, and the suction mechanism 43 simultaneously swing downwards, and then the rotating cutter 422 moves to a cutting position C The bobbin thread 60 remaining inside the winding space 513 is cut, and when the bobbin thread 60 inside the winding space 513 is cut by the cutter 422, the suction port 431 of the suction mechanism 43 will be positioned at the bobbin 51 The suction airflow A of the suction mechanism 43 can remove the bottom thread 60 cut by the cutter 422. As shown in the figure, the positioning mechanism 44 can restrict the passage space 514 of the first bobbin set 501. Is located directly above the spool piece 511, and when the cutter 422 is at the cutting position C, the through space 514 can be aligned with the cutter 422 at the cutting position C through the alignment mechanism 44, so that the cutter 422 is not only It can penetrate into the piercing space 514 to ensure that the cutter 422 can cut the bottom thread 60 and ensure that it does not interfere with the spool piece 511. Next, the movable drive source 411 of the movable mechanism 41 drives the movable arm 412 of the movable mechanism 41 Swing upward to make the thread cutting drive source 421, the cutter 422 and the suction mechanism 43 away from the bobbin 51. When the cutter 422 just leaves the through space 514 of the bobbin 51, the first movement component 311 The transmission member 3112 can drive the bobbin 51 to rotate to enhance the effect of the suction mechanism 43 to suck out the remaining bobbin thread 60, so that the bobbin 51 of the first bobbin set 501 assumes an initial state S2 with no bobbin thread 60 wound, and the removal is completed. Bottom line 60 homework.

請參閱圖15C所示，抽吸機構43組裝於活動機構41的活動臂412僅方便說明之用，亦即可將抽吸機構43組裝於縫紉機本體10的固定架14，使得活動臂412進行擺動時，抽吸機構43不會隨著活動臂412進行擺動，如圖所示，抽吸機構43的抽吸口431位於梭芯51的下方，並且，抽吸口431的外觀呈現漏斗樣態，藉此，當切刀422位在切斷位置C以切斷底線60時，抽吸機構43能承接被切刀422切斷後自然落下的底線60，使得底線60被由吸引氣流A帶離梭芯51。Please refer to FIG. 15C. The suction mechanism 43 is assembled on the movable arm 412 of the movable mechanism 41 for illustrative purposes only. That is, the suction mechanism 43 can be assembled on the fixing frame 14 of the sewing machine body 10 so that the movable arm 412 can swing At this time, the suction mechanism 43 will not swing with the movable arm 412. As shown in the figure, the suction port 431 of the suction mechanism 43 is located below the bobbin 51, and the suction port 431 has a funnel-like appearance. Thereby, when the cutter 422 is positioned at the cutting position C to cut the bobbin thread 60, the suction mechanism 43 can receive the bobbin thread 60 that has naturally fallen after being cut by the cutter 422, so that the bobbin thread 60 is taken away from the bobbin by the suction airflow A. 51.

請參閱圖15D所示，於較佳實施例中，切線機構42的切線傳動件423連接於一能產生氣流的空氣壓力源(圖未示)，其中，切線傳動件423設有複數個靠近於切刀422的吹氣孔423a，進而當切刀422位在切斷位置C以切斷底線60時，上述空氣壓力源(圖未示)會形成一由吹氣孔423a流出的吹出氣流B以防止被切斷的底線60纏繞於切線傳動件423。Please refer to FIG. 15D. In a preferred embodiment, the thread cutting transmission member 423 of the thread cutting mechanism 42 is connected to an air pressure source (not shown) capable of generating air flow. The blowing hole 423a of the cutting knife 422, and when the cutting knife 422 is at the cutting position C to cut the bottom thread 60, the air pressure source (not shown) will form a blowing airflow B flowing out of the blowing hole 423a to prevent being The cut bottom thread 60 is wound around the thread cutting transmission member 423.

請參閱圖16A所示，完成清除底線60之後，開始進行捲繞底線60作業，首先，第一運動組件311的第一驅動源3111產生旋轉動力以帶動第一連動組3113的第一主動皮帶輪3113a進行轉動，使第一連動組3113的第一皮帶3113c經由第一連動組3113的第一從動皮帶輪3113b帶動第一傳動件3112以運動軸線L為軸心進行轉動，進而使位在夾固空間3314內的底線60開始跟著第一傳動件3112進行旋轉，致使第一梭芯組501的梭芯51同步進行轉動而將底線60帶入梭芯51的捲繞空間513。Please refer to FIG. 16A. After the bottom thread 60 is removed, the winding operation of the bottom thread 60 is started. First, the first driving source 3111 of the first movement assembly 311 generates rotational power to drive the first driving pulley 3113a of the first linkage group 3113. Rotate, so that the first belt 3113c of the first interlocking group 3113 drives the first transmission member 3112 to rotate about the axis of motion L as the axis through the first driven pulley 3113b of the first interlocking group 3113, so that it is positioned in the clamping space The bobbin thread 60 in the 3314 starts to rotate with the first transmission member 3112, causing the bobbin 51 of the first bobbin group 501 to rotate synchronously to bring the bobbin thread 60 into the winding space 513 of the bobbin 51.

當第一梭芯組501的梭芯51捲繞底線60初期時，由於第一梭芯組501的第一捲線部511a的外徑小於第一梭芯組501的第二捲線部511b的外徑，使得底線60會先捲繞於梭芯51的第一捲線部511a以確保底線60先覆蓋於第一梭芯組501的穿設空間514，進而第一梭芯組501的梭芯51經過車縫作業之後所剩餘的底線60也會餘留在第一捲線部511a，使得切線機構42的切刀422位在切斷位置C時能確實切斷底線60，於較佳實施例中，為了進一步捲線動作初期確保底線60先捲繞第一捲線部511a，底線控制機構34的調整驅動源342帶動底線控制機構34的調整件341進行擺動，使調整件341的通孔3412a限制底線60偏向於連接盤3112a，而當底線60捲繞於第一捲線部511a達到一定圈數時(如10圈或20圈)，調整驅動源342再帶動調整件341，讓通孔3412a不限制底線60偏位，使底線60均勻捲繞於梭芯51的捲線軸件511，並且，當底線60捲繞於第一捲線部511a達到一定圈數時(如10圈或20圈)，夾線釋放機構33的釋放驅動源332也帶動夾線釋放機構33的釋放桿331進行擺動，使得釋放桿331的推動部3312推抵於刀片3112b的連接部3112d的下端(如圖16F所示)以釋放於底線60，讓位在夾固空間3314內的底線60線頭呈現鬆弛狀態而被一併捲入捲繞空間513，隨即，釋放驅動源332帶動推動部3312遠離於連接盤3112a，進而刀片3112b透過本身的彈力而使刀片3112b的刀刃部3112c接觸於連接盤3112a，接下來，當第一梭芯組501的梭芯51捲繞底線60而達到預設圈數時，第一梭芯組501的捲繞空間513內部已繞滿底線60，此時，第一運動組件311的第一驅動源3111停止轉動。When the bobbin 51 of the first bobbin set 501 is initially wound with the bobbin thread 60, because the outer diameter of the first winding part 511a of the first bobbin set 501 is smaller than the outer diameter of the second winding part 511b of the first bobbin set 501 , So that the bobbin thread 60 will be wound around the first winding part 511a of the bobbin 51 to ensure that the bobbin thread 60 first covers the threading space 514 of the first bobbin set 501, and then the bobbin 51 of the first bobbin set 501 passes through the car The bobbin thread 60 remaining after the sewing operation will also remain in the first bobbin thread portion 511a, so that the cutter 422 of the thread cutting mechanism 42 can cut the bobbin thread 60 when it is at the cutting position C. In a preferred embodiment, in order to further In the initial stage of the winding operation, ensure that the bobbin thread 60 is wound around the first bobbin part 511a first, and the adjustment drive source 342 of the bobbin thread control mechanism 34 drives the adjusting member 341 of the bobbin thread control mechanism 34 to swing, so that the through hole 3412a of the adjusting member 341 restricts the bobbin thread 60 from deflection to the connection When the bottom thread 60 is wound around the first winding part 511a to a certain number of turns (such as 10 or 20 turns), the driving source 342 is adjusted to drive the adjusting member 341, so that the through hole 3412a does not limit the deviation of the bottom thread 60. The bobbin thread 60 is evenly wound on the bobbin member 511 of the bobbin 51, and when the bobbin thread 60 is wound on the first bobbin part 511a to a certain number of turns (such as 10 or 20 turns), the thread clamping release mechanism 33 is released The driving source 332 also drives the release lever 331 of the thread clamping release mechanism 33 to swing, so that the pushing portion 3312 of the release lever 331 pushes against the lower end of the connecting portion 3112d of the blade 3112b (as shown in FIG. 16F) to release to the bottom thread 60, The thread end of the bottom thread 60 located in the clamping space 3314 is in a relaxed state and is rolled into the winding space 513. Then, the driving source 332 is released to drive the pushing part 3312 away from the connecting plate 3112a, and the blade 3112b is driven by its own elastic force. The cutting edge portion 3112c of the blade 3112b is brought into contact with the connecting plate 3112a. Next, when the bobbin 51 of the first bobbin set 501 is wound up to the preset number of turns, the winding space 513 of the first bobbin set 501 The bottom thread 60 has been wound inside, and at this time, the first driving source 3111 of the first movement assembly 311 stops rotating.

請參閱圖16B所示，停止捲繞底線60之後，由於無法確定底線60與夾具組件323之間的相對位置關係，所以底線控制機構34的調整驅動源342需帶動底線控制機構34的調整件341以樞接軸3411為軸心進行擺動，使調整件341的調整板3412牴觸到位在夾線器15與梭芯51之間的底線60，進而使調整板3412的通孔3412a限制位在夾線器15與梭芯51之間的底線60靠近於夾具組件323，藉此，接下來讓夾具組件323能確保夾固於位在夾線器15與梭芯51之間的底線60，為了達到前述效果，另一個實施程序是停止捲繞底線60之前，調整驅動源342帶動調整件341進行擺動，使調整板3412牴觸到位在夾線器15與梭芯51之間的底線60，進而限制位在夾線器15與梭芯51之間的底線60靠近於夾具組件323，讓最後捲繞於梭芯51的底線60能位在夾具組件323的移動路徑上。Please refer to FIG. 16B. After the winding of the bobbin thread 60 is stopped, since the relative positional relationship between the bobbin thread 60 and the clamp assembly 323 cannot be determined, the adjustment driving source 342 of the bobbin thread control mechanism 34 needs to drive the adjusting member 341 of the bobbin thread control mechanism 34 Swing with the pivot shaft 3411 as the axis, so that the adjusting plate 3412 of the adjusting member 341 touches the bottom thread 60 between the thread clamp 15 and the bobbin 51, and the through hole 3412a of the adjusting plate 3412 is restricted in the clamp The bottom thread 60 between the thread holder 15 and the bobbin 51 is close to the clamp assembly 323, so that the clamp assembly 323 can be clamped to the bottom thread 60 between the thread clamp 15 and the bobbin 51 in order to achieve For the aforementioned effect, another implementation procedure is to adjust the drive source 342 to drive the adjusting member 341 to swing before stopping the winding of the bobbin thread 60, so that the adjusting plate 3412 touches the bobbin thread 60 between the thread clamp 15 and the bobbin 51, thereby restricting The bottom thread 60 located between the thread clamp 15 and the bobbin 51 is close to the clamp assembly 323 so that the bottom thread 60 finally wound on the bobbin 51 can be positioned on the moving path of the clamp assembly 323.

請參閱圖16C所示，第一移動組件321的第一移動夾具驅動源3211帶動第一移動組件321的第一夾具傳動件3212向外延伸，而底線夾固機構32的夾具組件323受到第一夾具傳動件3212帶動而由一第一預備位置P1(如圖16A所示)沿著一相交於運動軸線L的第一路徑D1(如圖16D所示)移動至一夾固位置P2，使介在梭芯51與夾線器15之間的底線60位於活動夾具3231與固定夾具3232之間，於此實施例中，夾具組件323由第一預備位置P1移動到夾固位置P2的過程中，避開單元324的導引輪3244透過保持件3245的保持作用力3245a而持續接觸於組裝板3242的弧形導軌3242a，使得導引輪3244由弧形導軌3242a的一端移動至弧形導軌3242a的另一端時，避開單元324的擺動板3241會帶動第一移動組件321與夾具組件323進行逆時針方向的路徑擺動，進而改變第一移動夾具驅動源3211、第一夾具傳動件3212與夾具組件323三者與第一梭芯組501之間的相對位置以導致夾具組件323能避開於第一梭芯組501的梭芯51，藉此，夾具組件323沿著第一路徑D1移動至夾固位置P2時能透過避開單元324而不會碰觸到第一梭芯組501的梭芯51，請參閱圖16D所示，當底線夾固機構32的夾具組件323位於夾固位置P2時，活動夾具3231的擋銷3231b會牴觸於位在梭芯51與夾線器15之間的底線60，藉此，當底線60處於較鬆弛狀態時，擋銷3231b能限制底線60的局部長度位在活動夾具3231與固定夾具3232之間，進而能確保夾具組件323夾固於底線60時，底線60與夾具組件323之間的相對位置關係，隨後，夾具組件323的夾具驅動源3233帶動夾具組件323的活動夾具3231進行擺動，使活動夾具3231靠近於夾具組件323的固定夾具3232，進而使活動夾具3231與固定夾具3232在靠近於調整件341的地方夾固於位在梭芯51與夾線器15之間的底線60，此時，固定夾具3231的夾塊3232a移入夾槽3231a，進而使夾槽3231a與夾塊3232a兩者呈現密合狀態，使夾槽3231a與夾塊3232a夾固於底線60以避免底線60脫離於夾具組件323，而夾槽3231a與夾塊3232a共同夾固底線60的局部線段，在此，底線60區分為一位在梭芯51與夾具組件323之間的捲繞底線61，而底線60的其餘部分設為一組裝於夾線器15的供應源底線62。Please refer to FIG. 16C, the first moving clamp driving source 3211 of the first moving assembly 321 drives the first clamp transmission member 3212 of the first moving assembly 321 to extend outward, and the clamp assembly 323 of the bottom thread clamping mechanism 32 is subjected to the first The clamp transmission member 3212 is driven to move from a first preparation position P1 (as shown in FIG. 16A) to a clamping position P2 along a first path D1 (as shown in FIG. 16D) intersecting the movement axis L, so that the The bottom thread 60 between the bobbin 51 and the thread clamp 15 is located between the movable clamp 3231 and the fixed clamp 3232. In this embodiment, the clamp assembly 323 is moved from the first preparation position P1 to the clamping position P2. The guide wheel 3244 of the opening unit 324 continuously contacts the arc guide 3242a of the assembly plate 3242 through the holding force 3245a of the holder 3245, so that the guide wheel 3244 moves from one end of the arc guide 3242a to the other of the arc guide 3242a. At one end, the swing plate 3241 of the avoiding unit 324 will drive the first moving assembly 321 and the fixture assembly 323 to swing in a counterclockwise direction, thereby changing the first moving fixture driving source 3211, the first fixture transmission member 3212 and the fixture assembly 323 The relative positions between the three and the first bobbin set 501 cause the clamp assembly 323 to avoid the bobbin 51 of the first bobbin set 501, whereby the clamp assembly 323 moves along the first path D1 to be clamped The position P2 can pass through the avoiding unit 324 without touching the bobbin 51 of the first bobbin set 501. Please refer to FIG. 16D. When the clamp assembly 323 of the bobbin thread clamping mechanism 32 is at the clamping position P2, The stop pin 3231b of the movable clamp 3231 will touch the bottom thread 60 between the bobbin 51 and the thread clamp 15, so that when the bottom thread 60 is in a relatively slack state, the stop pin 3231b can limit the partial length of the bottom thread 60. Between the movable clamp 3231 and the fixed clamp 3232, it can be ensured that when the clamp assembly 323 is clamped to the bottom line 60, the relative positional relationship between the bottom line 60 and the clamp assembly 323. Then, the clamp drive source 3233 of the clamp assembly 323 drives the clamp assembly The movable clamp 3231 of 323 swings so that the movable clamp 3231 is close to the fixed clamp 3232 of the clamp assembly 323, and then the movable clamp 3231 and the fixed clamp 3232 are clamped in the position close to the adjusting member 341 between the bobbin 51 and the clamping wire. At this time, the clamping block 3232a of the fixing clamp 3231 is moved into the clamping groove 3231a, so that the clamping groove 3231a and the clamping block 3232a are in a close state, so that the clamping groove 3231a and the clamping block 3232a are clamped in The bottom thread 60 prevents the bottom thread 60 from detaching from the clamp assembly 323, and the clamping groove 3231a and the clamping block 3232a clamp a partial line of the bottom thread 60 together.

At this time, , The release drive source 332 of the thread clamping release mechanism 33 drives the release lever 331 of the thread clamping release mechanism 33 to swing, so that the pushing portion 3312 of the release lever 331 pushes against the lower end of the connecting portion 3112d of the blade 3112b, so that the cutting edge portion 3112 of the blade 3112b It is far from the connecting plate 3112a to allow the clamping space 3314 to present an open state for the bottom thread 60 to enter. Next, the first driving source 3111 of the first movement component 311 drives the first transmission component 3112 clockwise through the first linkage group 3113 Rotate in the direction to make the supply source bottom thread 62 pass through the inside of the clamping space 3314, and then release the drive source 332 to drive the release lever 331 to swing, so that the pushing portion 3312 of the release lever 331 is away from the lower end of the connecting portion 3112d of the blade 3112b, and then The blade 3112b uses its own elastic force to make the blade 3112b of the blade 3112b and the connecting plate 3112a clamp the supply bottom thread 62 (as shown in FIG. 16F) to wait for the next winding of the bottom thread 60, and then the second moving assembly The second moving fixture drive source 3221 of 322 drives the second fixture transmission member 3222 of the fixture assembly 323 to perform the first movement stroke, so that both the first fixture assembly 323 and the fixture assembly 323 are driven by the second fixture transmission member 3222 to move , The clamp assembly 323 is moved from the first preparation position P1 along a second path D2 that intersects the first path D1 to a first guiding position P3. When the clamping assembly 323 is located at the first guiding position P3, the supply source The bottom line 62 will contact the cutting edge portion 3112c of the blade 3112b, and then as shown in FIG. 16G and FIG. 16H, the first driving source 3111 of the first movement assembly 311 drives the first transmission member 3112 to move along the axis L through the first linkage group 3113. To rotate the axis counterclockwise, the blade 3112b is driven by the first transmission member 3112 to cut the supply source bottom thread 62. At this time, the end of the supply source bottom thread 62 is clamped by the blade 3112b, and the bottom thread 61 is wound. The end of the thread is clamped by the clamp assembly 323. In FIGS. 16A to 16H above, the bobbin case 52 is moved away from the bobbin core 51 in the axial direction for the convenience of description. In fact, the relative distance between the bobbin case 52 and the bobbin core 51 corresponds to that shown in the figure. The separation state S1 of 15A is shown, and in FIG. 16G, the bobbin 51 is moved out of the connecting plate 3112a in order to clearly show the angle state of the blade 3112b.

於前述圖16A至圖16E步驟中，為了避免夾具組件323沿著第一路徑D1進行移動時，夾具組件323會干涉到連接盤3112a與刀片3112b，第一運動組件311能帶動連接盤3112a與刀片3112b進行轉動，使得刀片3112b轉動到可避開夾具組件323的角度，但不限定在如圖顯示的角度。In the aforementioned steps of FIGS. 16A to 16E, in order to prevent the clamp assembly 323 from moving along the first path D1, the clamp assembly 323 will interfere with the connecting plate 3112a and the blade 3112b, and the first movement assembly 311 can drive the connecting plate 3112a and the blade The 3112b rotates so that the blade 3112b rotates to an angle that can avoid the clamp assembly 323, but is not limited to the angle shown in the figure.

After cutting the bobbin thread 60, start to install the winding bobbin thread 61 on the bobbin case 52 of the first bobbin set 501. First, the third driving source 3131 of the third movement assembly 313 drives the third linkage The group 3133 is far away from the third transmission member 3132. The restoring force 3134a of the resetting member 3134 acts on the pressing block 3132a to move the third transmission member 3132 toward the third driving source 3131, thereby moving the third transmission member 3132 Can drive the bobbin case 52 of the first bobbin set 501 to be assembled to the bobbin 51 of the first bobbin set 501, so that the bobbin case 52 of the first bobbin set 501 and the bobbin 51 of the first bobbin set 501 are separated from each other The separated state S1 is transformed into an assembled state S3 of mutual assembly. At this time, the winding bobbin thread 61 contacts the open end 524 of the bobbin case 52, so that the winding bobbin thread 60 assumes a tensioned state.

請參閱圖17B所示，當捲繞底線60接觸於梭殼52的開口端524時，第二運動組件312的第二驅動源3121產生旋轉動力以帶動第二連動組3123的第二主動皮帶輪3123a進行轉動，使第二連動組3123的第二皮帶3123c經由第二連動組3123的第二從動皮帶輪3123b帶動第二傳動件3122以運動軸線L為軸心進行轉動，而當第二傳動件3122進行轉動時，同步組件314的同步凸柱3142受同步凹槽3141的限制無法移動，使得第二傳動件3122透過同步組件314而帶動第三運動組件313的第三傳動件3132進行轉動，進而使第一梭芯組501的梭殼52同步進行轉動，如圖所示，第二驅動源3121透過第二傳動件3122而先帶動第一梭芯組501的梭殼52進行順時針方向轉動，而後第二驅動源3121再帶動第一梭芯組501的梭殼52進行逆時針方向轉動，使得進行轉動的梭殼52能將捲繞底線60導入梭殼52的導線溝527，讓捲繞底線61的局部線段位在梭殼52的殼體521與梭殼52的夾線彈片528之間。Please refer to FIG. 17B. When the winding bobbin thread 60 contacts the open end 524 of the bobbin case 52, the second driving source 3121 of the second movement assembly 312 generates rotational power to drive the second driving pulley 3123a of the second linkage group 3123 The second belt 3123c of the second linkage group 3123 drives the second transmission member 3122 to rotate about the axis of movement L as the axis through the second driven pulley 3123b of the second linkage group 3123, and when the second transmission member 3122 When rotating, the synchronization protrusion 3142 of the synchronization assembly 314 cannot move due to the limitation of the synchronization groove 3141, so that the second transmission member 3122 drives the third transmission member 3132 of the third movement assembly 313 to rotate through the synchronization assembly 314, thereby causing The bobbin case 52 of the first bobbin set 501 rotates synchronously. As shown in the figure, the second driving source 3121 first drives the bobbin case 52 of the first bobbin set 501 to rotate clockwise through the second transmission member 3122, and then The second driving source 3121 then drives the bobbin case 52 of the first bobbin set 501 to rotate counterclockwise, so that the rotating bobbin case 52 can guide the winding bobbin thread 60 into the wire groove 527 of the bobbin case 52 to wind the bobbin thread 61 The partial line segment is located between the housing 521 of the bobbin case 52 and the thread clamping elastic piece 528 of the bobbin case 52.

請參閱圖17C所示，接下來，第二移動組件322的第二移動夾具驅動源3221帶動夾具組件323的第二夾具傳動件3222進行第二段移動行程，使第一夾具組件323與夾具組件323兩者受到第二夾具傳動件3222帶動朝向遠離連接盤3112a的方向進行移動，使夾具組件323由第一導引位置P3沿著一平行於第二路徑D2的第三路徑D3移動至一第二預備位置P4，如圖17D所示，夾具組件323移動至第二預備位置P4的過程中，第一移動組件321的第一夾具傳動件3212接觸到避開單元324的滾輪3243，使避開單元324的擺動板3241進行擺動，進而使避開單元324的導引輪3244分離於弧形導軌3242a，藉此，底線夾固機構32的夾具組件323拉動捲繞底線61，使捲繞底線61被導入夾線彈片528的導引口528a，進而夾線彈片528能將捲繞底線61從導線溝527導引至導線孔526。Please refer to FIG. 17C. Next, the second moving fixture driving source 3221 of the second moving assembly 322 drives the second fixture transmission member 3222 of the fixture assembly 323 to perform a second movement stroke, so that the first fixture assembly 323 and the fixture assembly 323 are driven by the second clamp transmission member 3222 to move in a direction away from the connecting plate 3112a, so that the clamp assembly 323 moves from the first guiding position P3 along a third path D3 parallel to the second path D2 to a first The second preparation position P4, as shown in FIG. 17D, during the movement of the clamp assembly 323 to the second preparation position P4, the first clamp transmission member 3212 of the first moving assembly 321 contacts the roller 3243 of the avoiding unit 324, so that the avoiding The swing plate 3241 of the unit 324 swings to separate the guide wheel 3244 of the avoiding unit 324 from the arc guide 3242a, whereby the clamp assembly 323 of the bobbin thread clamping mechanism 32 pulls the winding bobbin thread 61 to wind the bobbin thread 61 It is guided into the guide opening 528 a of the wire clamping elastic piece 528, and then the wire clamping elastic piece 528 can guide the winding bobbin thread 61 from the wire groove 527 to the wire hole 526.

請參閱圖17E所示，當夾具組件323位於第二預備位置P4時，第一移動組件321的第一移動夾具驅動源3211再度帶動第一移動組件321的第一夾具傳動件3212向外延伸，使第一夾具傳動件3212帶動夾具組件323由第二預備位置P4沿著一平行於第一路徑D1的第四路徑D4移動至一第二導引位置P5，其中，夾具組件323移動至第二導引位置P5的過程中，捲繞底線61會先碰觸到梭殼52的勾臂529，而後捲繞底線61會推抵擋線片530的彈臂530a，讓彈臂530a產生形變，使得捲繞底線61被導引至勾臂529的線孔529a內部，藉此，即完成將捲繞底線61安裝於梭殼52的作業，其中，當捲繞底線61位在線孔529a內部時，彈臂530a因為沒有被捲繞底線61推抵而重疊於線孔529a，使得捲繞底線61受彈臂530a阻擋而能避免脫離於線孔519a。As shown in FIG. 17E, when the clamp assembly 323 is located at the second preparation position P4, the first moving clamp driving source 3211 of the first moving assembly 321 again drives the first clamp driving member 3212 of the first moving assembly 321 to extend outward. The first clamp transmission member 3212 drives the clamp assembly 323 from the second preparation position P4 to move along a fourth path D4 parallel to the first path D1 to a second guiding position P5, wherein the clamp assembly 323 moves to the second guide position P5. In the process of guiding the position P5, the winding bobbin thread 61 will first touch the hook arm 529 of the bobbin case 52, and then the winding bobbin thread 61 will push against the elastic arm 530a of the thread piece 530, causing the elastic arm 530a to deform, causing the winding The winding bobbin thread 61 is guided to the inside of the thread hole 529a of the hook arm 529, thereby completing the work of installing the winding bobbin thread 61 on the bobbin case 52. When the winding bobbin thread 61 is inside the thread hole 529a, the elastic arm Because 530a is not pushed by the winding bobbin thread 61 and overlaps with the thread hole 529a, the winding bobbin thread 61 is blocked by the elastic arm 530a and can avoid being separated from the thread hole 519a.

請參閱圖17F所示，捲繞底線61被導引至勾臂529的線孔529a內部，夾具組件323的夾具驅動源3233帶動夾固組件的活動夾具3231進行擺動，使活動夾具3231遠離於夾具組件323的固定夾具3232，進而使夾具組件323放開捲繞底線61的線頭，最後，夾具組件323透過第一移動組件321與第二移動組件322而從第二導引位置P5移回至第一預備位置P1，使夾具組件323等待將底線60安裝於梭殼52。Please refer to FIG. 17F, the winding bobbin thread 61 is guided to the inside of the wire hole 529a of the hook arm 529, and the clamp driving source 3233 of the clamp assembly 323 drives the movable clamp 3231 of the clamp assembly to swing, so that the movable clamp 3231 is away from the clamp The fixing clamp 3232 of the assembly 323, in turn, allows the clamp assembly 323 to release the end of the winding bobbin thread 61. Finally, the clamp assembly 323 moves back from the second guiding position P5 to the second guiding position P5 through the first moving assembly 321 and the second moving assembly 322 The first preparation position P1 makes the clamp assembly 323 wait for the bottom thread 60 to be installed on the bobbin case 52.

請參閱圖18所示，於第二較佳實施例中，與第一較佳實施例的差別在於第一運動組件311、第二運動組件312、第三運動組件313與同步組件314四者之間的組裝方式，如圖所示，第二運動組件312的第二傳動件3122活動穿設於第一運動組件311的第一傳動件3112，而第二運動組件312的第二連動組3123設為單一個空心軸，第三傳動件3132活動組裝於第二連動組3123的外周，並透過同步組件314的同步凸柱3142組裝於第二傳動件3122，其中，第一傳動件3112與第三傳動件3132分別位於第二傳動件3122的相對兩側，此外，第三運動組件313的第三連動組3133設有一可帶動於第三傳動件3132軸向位移的連動齒條3133a以及一組裝於第三驅動源3131的連動齒輪3133b，則連動齒條3133a嚙合於連動齒輪3133b，其中，同步組件314的同步凹槽3141形成於第二連動組3123，使同步凹槽3141呈現長條狀樣態，而使同步凸柱3142同時穿設於第三傳動件3132、第二連動組3123以及第二傳動件3122。Referring to FIG. 18, in the second preferred embodiment, the difference from the first preferred embodiment is that one of the first movement component 311, the second movement component 312, the third movement component 313, and the synchronization component 314 As shown in the figure, the second transmission member 3122 of the second movement assembly 312 movably penetrates the first transmission member 3112 of the first movement assembly 311, and the second linkage group 3123 of the second movement assembly 312 is provided with For a single hollow shaft, the third transmission member 3132 is movably assembled on the outer periphery of the second linkage group 3123, and is assembled to the second transmission member 3122 through the synchronization protrusion 3142 of the synchronization assembly 314. Among them, the first transmission member 3112 and the third transmission member 3132 The transmission members 3132 are respectively located on opposite sides of the second transmission member 3122. In addition, the third linkage group 3133 of the third movement assembly 313 is provided with a linkage rack 3133a capable of driving the axial displacement of the third transmission member 3132 and an assembly in The linkage gear 3133b of the third driving source 3131, the linkage rack 3133a meshes with the linkage gear 3133b, wherein the synchronization groove 3141 of the synchronization assembly 314 is formed in the second linkage group 3123, so that the synchronization groove 3141 is elongated. , So that the synchronization protruding column 3142 passes through the third transmission member 3132, the second linkage group 3123, and the second transmission member 3122 at the same time.

於此實施例中，當第二運動組件312的第二驅動源3121產生旋轉動力，使第二驅動源3121帶動第二傳動件3122相對於第一傳動件3112進行轉動，此時，同步組件314的同步凸柱3142不會受到第一傳動件3112影響而進行轉動，而同步組件314的同步凹槽3141同步與第二傳動件3122進行轉動，此外，第三運動組件313的第三驅動源3131產生旋轉動力，第三連動組3133的連動齒輪3133b帶動第三連動組3133的連動齒條3133a進行移動，使第三傳動件3132沿著運動軸線L進行移動，而當第三傳動件3132進行移動時，同步組件314的同步凸柱3142會沿著同步組件314的同步凹槽3141移動，使得第三傳動件3132透過同步組件314而帶動第二傳動件3122整體進行軸向移動。In this embodiment, when the second driving source 3121 of the second moving assembly 312 generates rotational power, the second driving source 3121 drives the second transmission member 3122 to rotate relative to the first transmission member 3112. At this time, the synchronization assembly 314 The synchronization protrusion 3142 will not be affected by the first transmission member 3112 to rotate, and the synchronization groove 3141 of the synchronization assembly 314 rotates synchronously with the second transmission member 3122. In addition, the third driving source 3131 of the third movement assembly 313 Rotational power is generated, the interlocking gear 3133b of the third interlocking group 3133 drives the interlocking rack 3133a of the third interlocking group 3133 to move, so that the third transmission member 3132 moves along the movement axis L, and when the third transmission member 3132 moves At this time, the synchronization protrusion 3142 of the synchronization assembly 314 moves along the synchronization groove 3141 of the synchronization assembly 314, so that the third transmission member 3132 drives the second transmission member 3122 to move axially as a whole through the synchronization assembly 314.

請參閱圖19所示，於第三較佳實施例中，與第二較佳實施例的差別在於梭芯組運動機構31沒有同步組件314以及第三運動組件313的第三傳動件3132設為一板件而組裝於第二運動組件312的第二驅動源3121，使第三傳動件3132沒有同軸設置於運動軸線L，其中，當第三運動組件313的第三驅動源3131帶動第三傳動件3132沿著運動軸線L的軸線方向進行移動時，第二運動組件312整體(包含第二驅動源3121、第二傳動件3122與第二連動組3123)同時沿著進行移動，使得梭殼52進行移動以分離於梭芯51，於此實施例中，第三傳動件3132能直接連接於第三驅動源3131，但是，第三傳動件3132也能經由第三連動組3133來連接於第三驅動源3131。Please refer to FIG. 19, in the third preferred embodiment, the difference from the second preferred embodiment is that the bobbin set movement mechanism 31 does not have a synchronization assembly 314 and the third transmission member 3132 of the third movement assembly 313 is set to A plate is assembled to the second driving source 3121 of the second movement assembly 312, so that the third transmission member 3132 is not coaxially arranged on the movement axis L. When the third driving source 3131 of the third movement assembly 313 drives the third transmission When the member 3132 moves along the axis direction of the movement axis L, the entire second movement assembly 312 (including the second driving source 3121, the second transmission member 3122 and the second linkage group 3123) simultaneously moves along, so that the bobbin case 52 Move to separate from the bobbin 51. In this embodiment, the third transmission member 3132 can be directly connected to the third drive source 3131, but the third transmission member 3132 can also be connected to the third drive source 3131 via the third linkage group 3133. Drive source 3131.

然而，第三傳動件3132組裝於第二驅動源3121僅方便說明之用，亦即第三傳動件3132可組裝於第一運動組件311的第一驅動源3111，進而第三傳動件3132透過第三驅動源3131沿著運動軸線L的軸線方向進行移動時，第一運動組件311整體(包含第一驅動源3111、第一傳動件3112與第一連動組3113)可同時沿著運動軸線L進行移動，使得梭芯51進行移動以分離於梭殼52。However, the assembly of the third transmission member 3132 in the second driving source 3121 is only for convenience of illustration, that is, the third transmission member 3132 can be assembled in the first driving source 3111 of the first movement assembly 311, and the third transmission member 3132 passes through the first driving source 3111. When the three drive sources 3131 move along the axis direction of the movement axis L, the entire first movement assembly 311 (including the first drive source 3111, the first transmission member 3112 and the first linkage group 3113) can move along the movement axis L at the same time The movement causes the bobbin 51 to move to separate from the bobbin case 52.

另外，於此實施例中，在底線60捲繞於梭芯51之前，底線夾固機構32的夾具組件323能先暫時夾固於供應源底線62，隨後，夾線釋放機構33的釋放驅動源332帶動夾線釋放機構33的釋放桿331進行擺動，使釋放桿331的推動部3312推抵刀片3112b的連接部3112d的下端，進而刀片3112b的刀刃部3112遠離於連接盤3112a以讓夾固空間3314呈現開啟狀態，接下來，夾具組件323受到第一移動組件321與第二移動組件322的帶動而能將供應源底線62暫時脫離於夾固空間3314，藉此，於清除底線60的過程中，因為供應源底線62暫時脫離於夾固空間3314而能避免第一傳動件3112轉動過程中從夾線器15拉出多餘的底線60，隨後，於完成清除底線60之後，第一、二移動組件321、322帶動夾具組件323進行移動，讓供應源底線62回到夾固空間3314的內部，之後，釋放驅動源332帶動釋放桿331進行擺動，使得釋放桿331的推動部3312遠離於刀片3112b的連接部3112d的下端，進而刀片3112b透過本身的彈力而使刀片3112b的刀刃部3112c與連接盤3112a共同夾固供應源底線62。In addition, in this embodiment, before the bobbin thread 60 is wound on the bobbin 51, the clamp assembly 323 of the bobbin thread clamping mechanism 32 can be temporarily clamped to the supply source bobbin thread 62, and then the thread clamping release mechanism 33 releases the driving source 332 drives the release lever 331 of the clamping release mechanism 33 to swing, so that the pushing portion 3312 of the release lever 331 pushes against the lower end of the connecting portion 3112d of the blade 3112b, and the cutting edge portion 3112 of the blade 3112b is further away from the connecting disk 3112a to allow the clamping space 3314 is in an open state. Next, the clamp assembly 323 is driven by the first moving assembly 321 and the second moving assembly 322 to temporarily detach the supply bottom thread 62 from the clamping space 3314, thereby, in the process of removing the bottom thread 60 , Because the supply source bottom thread 62 is temporarily detached from the clamping space 3314, it can prevent the excess bottom thread 60 from being pulled from the thread clamp 15 during the rotation of the first transmission member 3112. Then, after the bottom thread 60 is removed, the first and second movements The components 321 and 322 drive the clamp assembly 323 to move, allowing the bottom thread 62 of the supply source to return to the inside of the clamping space 3314, and then release the driving source 332 to drive the release lever 331 to swing, so that the pushing portion 3312 of the release lever 331 is away from the blade 3112b The lower end of the connecting portion 3112d of the blade 3112b allows the blade 3112b of the blade 3112b and the connecting plate 3112a to clamp the bottom thread 62 of the supply source through its own elastic force.
