Abstract

A bobbin module operation mechanism of the present invention is used with a bobbin and a bobbin case and includes three operation modules. Each of the three operation modules includes a transferring member. Two of the transferring members are coaxially disposed on an operation axis. The bobbin and the bobbin case are rotated along the operation axis. The remaining transferring member is moved along a direction of the operation axis and moves the bobbin case away from the bobbin. Therefore, the bobbin and the bobbin case are separated from each other. After separating the bobbin case and the bobbin from a rotary hook by a sewing operation, the three operation modules can automatically separate the bobbin case from the bobbin, and wind the bobbin thread on the bobbin.

Description

Bobbin module operation mechanism {BOBBIN MODULE MOTION MECHANISM}

The present invention relates to a bobbin module operation mechanism applied to wind a bobbin thread, and in particular, the bobbin and the bobbin case can be separated and rotated, and the bobbin and the bobbin case can be separated from each other. It relates to a bobbin module operation mechanism.

When using a sewing machine with the lockstitch principle, whether it is a full-rotary rotary hook or a semi-rotary swing hook, there is a bobbin that can wind the bobbin thread. . Also, most sewing machines using the lockstitch principle have a bobbin case for accommodating a bobbin.

However, in order to increase the rotational speed of the sewing machine, the capacity of the bobbin for accommodating the bobbin thread cannot be too large, while the length of the bobbin thread is relatively limited, and thus, the bobbin is frequently Must be replaced; In addition, when the bobbin thread is replaced, not only the sewing machine must stop the sewing operation, but also the operator must manually replace the bobbin thread, making it difficult to increase production efficiency.

In order to overcome the aforementioned drawbacks, there are automatic bobbin replacement devices in the sewing machine industry. When the bobbin thread wound on the bobbin is detected as falling, the automatic bobbin replacement device will separate the bobbin case and bobbin from the rotary hook at the same time. Accordingly, in order to achieve the function of automatically replacing the bobbin, both the bobbin case and the bobbin are separated from the hook, and then a different set of bobbin case and a bobbin full of bobbin thread are assembled to the rotary hook at the same time.

However, the automatic bobbin replacement device described above simultaneously separates the bobbin case and the bobbin from which the bobbin thread is almost separated from the rotary hook; After that, the bobbin from which the bobbin thread has fallen almost remains there and has a part of the bobbin thread that is located inside the bobbin case. This allows the operator to take time not only to manually separate the bobbin from which the bobbin thread is almost removed from the bobbin case, but also to manually remove the bobbin thread remaining in the bobbin. In addition, after removing the bobbin thread from the bobbin, the operator must manually mount the bobbin on a winder to wind the bobbin thread on the bobbin, which leads to increased manual work time.

The main object of the present invention is to not only separate the bobbin and the bobbin case from each other, but also to separate the bobbin and the bobbin case to rotate, thereby removing the remaining bobbin thread and completing the work of winding the bobbin thread in a short time. Help; Therefore, manual work by an operator is not required.

To achieve the above object, the bobbin module operation mechanism of the present invention can drive the bobbin and the bobbin case in an assembled state, and includes a first operation module, a second operation module, and a third operation module. The first motion module has a first transmission member that can rotate coaxially along a motion axis, and the bobbin can be driven to rotate synchronously by the first transmission member; Further, the second operation module has a second transmission member capable of synchronously rotating along the operation axis, and the bobbin case can be driven to rotate synchronously by the second transmission member; The third motion module has a third transfer member, and the third transfer member can move along the direction of the motion axis, and thus, between the bobbin and the bobbin case by the third transfer member from a state in which both the bobbin and the bobbin case are assembled. It can be changed to a separate state.

In this embodiment, the third transmission member is disposed coaxially on the movement axis, and thus, the third transmission member can move coaxially along the movement axis; The third transmission member is movably coupled to the first transmission member or the second transmission member, and the first transmission member and the second transmission member are movably sleeved on two ends of the third transmission member, respectively. ), and thus, the third transmission member is movable relative to the first and second transmission members; In addition, a synchronization module is disposed between the third transmission member and one of the first transmission member and the second transmission member, and the synchronization module rotates or linearly rotates the third transmission member and one of the first transmission member and the second transmission member at the same time. Lets go. In a preferred embodiment, the synchronization module has a synchronization groove and a synchronization protruding pillar, the synchronization groove is formed on one of the first transmission member and the second transmission member, and the synchronization protruding pillar is It is formed on the third transmission member and passes through the synchronization groove.

In another embodiment, the third transmission member is assembled to the first operation module or the second operation module, and may be driven to move the first operation module or the second operation module as a whole.

In addition, the third operation module further has a returning member, and the restoration member may generate a restoring force acting on the third transmission member, and thus, the third transmission member And keep the bobbin case assembled.

In addition, one of the second transmission member and the third transmission member is connected to the bobbin case; A limiting assembly is disposed between the bobbin case and the transmission member connected to the bobbin case, and the limiting assembly may limit movement or rotation of the bobbin case with respect to the transmission member connected to the bobbin case. In this embodiment, the limiting assembly has an annular groove formed on the transmission member and a latch disposed on the bobbin case, the latch, in order to limit the bobbin case from having axial movement, It can be snapped into the annular groove.

In a preferred embodiment, the bobbin case has a bobbin shaft sleeved on the transmission member, and the limiting assembly has a positioning groove and a positioning protrusion; One of the positioning groove and the positioning protrusion is formed on the bobbin shaft, and the other of the positioning groove and the positioning protrusion is formed on the transmission member; The positioning protrusion enters the positioning groove to limit rotation of the bobbin case.

The invention features three transmission members, the two transmission members being arranged coaxially on the axis of motion. One of the two transmission members can rotate, and thus, the rotating transmission member can drive the bobbin to rotate about an axis of motion; The other of the two transmission members can drive the bobbin case to rotate about an axis of motion; Due to this, the remaining transmission member moves, causing the moving transmission member to drive the bobbin case to move linearly along the motion axis. By doing so, the two rotating transmission members cooperating with the movable transmission member can not only separate the bobbin and bobbin case from each other, but also allow the bobbin and bobbin case to separate and rotate, thereby removing the remaining bobbin thread. It can help the operator to complete the removal and winding of the main compartment in a short time; Therefore, manual work by an operator is not required.

See FIG. 13. The bobbin 51 of the bobbin module 50 is mounted on the first transmission member 3112 of the first operation module 311, and the alignment mechanism 44 is between the bobbin 51 and the first transmission member 3112. Is placed in The alignment mechanism 44 may limit the through space 514 of the bobbin 51 to be directly above the bobbin 51 when the bobbin 51 is assembled to the first transmission member 3112, which is Bring 514 closer to the cutter 422 of the thread cutting mechanism 42. As shown in the figure, the alignment mechanism 44 has a guiding module 441 and a positioning module 442. The guiding module 441 is composed of two magnets 4411. The positioning module 442 is composed of a bump 4241 and a positioning groove 4242, which can be engaged with each other. As shown in the figure, the two magnets 4411 are assembled to the bobbin 51 and the first transmission member 3112, respectively. In addition, the bump 4241 is formed on the first transmission member 3112, and the positioning groove 4242 is formed on the bobbin 51. When the bobbin 51 is assembled to the first transmission member 3112, the bobbin 51 may be in a freely rotatable state. Subsequently, the first transmission member 3112 is driven to rotate the bobbin 51, and thus, the two magnets 4411 are each other to shorten the relative distance between the bobbin 51 and the first transmission member 3112. Magnetically attracted to, and the bump 4241 further engages the positioning groove 4242 to limit the relative angular position between the bobbin 51 and the first transmission member 3112; Therefore, the bobbin 51 cannot rotate with respect to the eleventh transmission member 3112, and when the first transmission member 3112 stops rotating and is positioned at an angle, the through space 514 corresponds to the cutter 422 It may be located directly above the bobbin (51).

See FIG. 14. In a specific application, the rotary hook 12 of the sewing machine body 10 and the bobbin module operation mechanism 31 of the bobbin thread introduction device 30 are assembled with a bobbin module 50 wound with a bobbin thread 60, respectively; Accordingly, the bobbin module 50 of the rotary hook 12 is set as the first bobbin module 501, and the bobbin module 50 assembled in the bobbin module operation mechanism 31 is set as the second bobbin module 502 do; Further, the bobbin thread 60, arranged on the sewing machine body 10, is assembled to the thread gripper 15 of the sewing machine body 10; The bobbin thread 60 disposed in the sewing machine body 10 passes through the through hole 3412a of the bobbin thread control mechanism 34, and thus, a partial section of the bobbin thread 60 disposed in the sewing machine body 10 It can be located inside the clamping space 3314 of the thread release mechanism 33, whereby the edge portion 3112c of the blade 3112b and the connection plate 3112a of the first transmission member 3112 are connected to the sewing machine body 10 ) To clamp the bobbin thread 60 disposed in the inside at once.

See Fig. 14B. When the sewing machine main body 10 performs a sewing operation such that the amount of the lower thread 60 of the first bobbin module 501 is substantially reduced, the movement driving source 211 of the bobbin module moving assembly 21 generates moving power. ; Accordingly, the bobbin module moving assembly 21 moves close to the rotary hook 12 as a whole along the transfer rod 212, and the movable frame 22 moves the first and second sets of assemblies 23 and 24, respectively. The rotary hook 12 of the sewing machine main body 10 and the bobbin module operation mechanism 31 of the bobbin thread introduction device 30 are driven to be approached.

See FIGS. 14C and 14D. When the first and second sets of assemblies 23 and 24 approach the rotary hook 12 of the sewing machine body 10 and the bobbin module operation mechanism 31 of the bobbin thread introduction device 30, respectively, the first assembly The first fixing jaw 232 of (23) is in contact with the bobbin case 52 of the first bobbin module 501, while the second fixing jaw 242 of the second bobbin module 24 is a second bobbin module. It contacts the bobbin case 52 of 502. Subsequently, the first jaw driver 234 drives the first movable jaw 233 to swing, and thus, the first clamping portion 233a of the first movable jaw 233 is attached to the first fixed jaw 232 It moves closer, and the first clamping part 233a is fixed to the latch clip 3151b disposed on the first bobbin module 501. By doing so, the first movable jaw 233 and the first fixed jaw 232 clamp the first bobbin module 501 collectively; On the other hand, the second jaw driver 244 is driven to swing the second movable jaw 243, and thus, the second clamping portion 243a of the second movable jaw 243 is attached to the second fixed jaw 242. It moves closer, and the second clamping part 243a is fixed to the latch clip 3151b disposed on the second bobbin module 502. In this way, the second movable jaw 243 and the second fixed jaw 242 clamp the second bobbin module 502 together.

See FIGS. 14E and 14F. When the Article 1 assembly 23 and the Article 2 assembly 24 clamp the first bobbin module 501 and the second bobbin module 502, respectively, the movement driving source 211 of the bobbin module movement assembly 21 ) Generates movement power; Accordingly, the bobbin module moving assembly 21 is moved away from the rotary hook 12 along the transmission rod 212 as a whole, and the first set assembly 23 attaches the first bobbin module 501 to the sewing machine body ( 10) is driven to move away from the rotary hook 12, on the other hand, the second assembly 24 moves the second bobbin module 502 into the bobbin module operation mechanism 31 of the bobbin thread introduction device 30. It drives to move away from. By doing so, the first set assembly 23 can separate the first bobbin module 501 from the rotary hook 12 through the bobbin module moving assembly 21, and the second set assembly 24 is The bobbin module 502 is separated from the bobbin module operating mechanism 31 via the bobbin module moving assembly 21.

Subsequently, the rotation drive source 251 of the bobbin module rotation assembly 25 may generate rotation power, and thus, the first transmission gear 252a of the transmission module 252 and the second transmission of the transmission module 252 The gear 252b drives to rotate the transmission rod 212 of the bobbin module moving assembly 21, which causes the transmission rod 212 to rotate the movable frame 22 clockwise in the direction of the arrow in the drawing, Thus, the second bobbin module 502 is located right in front of the rotary hook 12.

See FIGS. 14G and 14H. Again, the movement driving source 211 of the bobbin module movement assembly 21 generates movement power, and thus, the movement driving source 211 transmits the movable frame 22 along the transmission rod 212 to the sewing machine body 10 And the second bobbin module 502 is mounted on the rotary hook 12; And, the second jaw driver 244 of the second jaw assembly 24 is driven to move the second clamping portion 243a of the second movable jaw 243 away from the latch clip 3151b, and thus, The second bobbin module 502 is actually assembled to the rotary hook 12; Now, the first jaw assembly 23 still clamps the first bobbin module 501.

See Figs. 14I, 14J and 14K. The second bobbin module 502 is assembled to the rotary hook 12, and the movable frame 22 of the bobbin exchange device 20 is formed by the bobbin module moving assembly 21 and the bobbin module rotating assembly 25. It is driven to bring the jaw assembly 23 close to the bobbin module operation mechanism 31 of the bobbin thread introduction device 30, which causes the first bobbin module 501 to be mounted on the bobbin module operation mechanism 31; When the first bobbin module 501 is mounted on the bobbin module operation mechanism 31, the third transmission member 3132 of the third operation module 313 moves the bobbin shaft 522 of the first bobbin module 501. Pass, and thus, in order to limit the rotation of the bobbin case 52 of the first bobbin module 501 about the motion axis L, the positioning protrusion 3152a of the limiting assembly 315 is ) Into the positioning groove 3152b.

As shown in the figure, when the positioning protrusions 3152A of the restriction assembly 315 fit into the positioning grooves 3152B of the restriction assembly 315, the first jaw driver 234 of the first jaw assembly 23 ) Drives the first clamping portion 233A of the first movable jaw 233 away from the latch clip 3151B disposed in the first bobbin module 501; The latch clip 3151b disposed in the first bobbin module 501 closes the latch 3151c in order to limit the bobbin case 52 of the second bobbin module 502 from having movement along the motion axis L. Rebound to snap into the annular groove 3151A of the restriction assembly 315.

After that, the movement driving source 211 of the bobbin module movement assembly 21 generates movement power to drive the movable frame 22 to move away from the rotary hook 12, and now, the first set assembly (23) and the second assembly 24 do not hold the bobbin module 501 and the second module 502, respectively, which means that both the first assembly 23 and the second assembly 24 are bobbins. Wait for the next operation to hold the module 50.

See Fig. 14L. When the first bobbin module 501 is mounted on the bobbin module operation mechanism 31, the bobbin 51 of the first bobbin module 501 is close to the connection plate 3112a of the first transmission member 312. At this time, the bobbin 51 may be in a freely rotatable state. In addition, the first transmission member 3112 drives the bobbin 51 to rotate in a clockwise direction, and thus, the bobbin 51 of the first bobbin module 501 rotates about the motion axis L. To allow, the guiding modules 441 of the two magnets 4411 are magnetically attracted to each other; In addition, in order to limit the relative angular position between the bobbin 51 of the first bobbin module 501 and the first transmission member 3112, the bump 4241 of the alignment mechanism 44 is a positioning groove of the alignment mechanism 44 Meshes with (4422); Further, when the first transmission member 3112 rotates several times and then stops at an angular position, the through space 514 of the first bobbin module 501 may be positioned directly above the spool member 511; In addition, when the first transmission member 3112 rotates, the bobbin 51 of the first bobbin module 50 may rotate through the first transmission member 3112, and the housing 521 and the clamping elastic piece ( The partial bobbin thread 60 exposed outside the thread guiding hole 526 as well as the partial bobbin thread 60 between 528 can be wound again into the bobbin case 52 by the rotating bobbin 51, which For subsequent thread cutting operation. In this embodiment, the bobbin 51 has two through spaces 514; The two through spaces 514 are separated by 180°; Further, the alignment mechanism 44 and the through space 514 are both formed 180° symmetrically. Accordingly, the bow number 51 has two angles for positioning.

See FIG. 15A. When neither the first jaw assembly 23 nor the second jaw assembly 24 clamps the bobbin module 50, the residual bobbin seal 60 in the first bobbin module 501 begins to be removed. First, the third driving source 3131 of the third operation module 313 drives the third transmission member 3132 of the third operation module 313 to move along the operation axis L, which is a synchronization module. The synchronous protruding pillar 3142 of 314 allows it to move toward the end portion of the synchronous groove 3141; Accordingly, the moving second transmission member 3132 can drive the bobbin case 52 of the first bobbin module 501 to be separated in the axial direction from the bobbin 51 of the first bobbin module 501, The bobbin case 52 of the first bobbin module 501 and the bobbin 51 of the first bobbin module 501 are separated from each other to represent a separated state (S1).

See FIG. 15B. Subsequently, the cutting drive source 421 of the thread cutting mechanism 42 drives the cutter 422 of the thread cutting mechanism 42 to rotate, and the suction mechanism 43 operates to generate the suction airflow A. Start. And, the movable drive source 411 of the movable mechanism 41 drives the movable arm 412 of the movable mechanism 41 to swing, and the cutting drive source 421, the cutter 422, and the suction mechanism 43 At the same time, the cutter 422 rotates downwardly and moves to the cutting position C so as to cut the remaining bobbin thread 60 inside the winding space 513. 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 located on one side of the bobbin 51, which is The suction airflow A of the mechanism 43 causes the bobbin thread 60 cut by the cutter 422 to be removed. As shown in the figure, since the alignment mechanism 44 can limit the through space 514 of the first bobbin module 501 directly above the spool member 511, the cutter 422 is in the cutting position (C) When in, the through space 514 can be aligned with the cutter 422 positioned in the cutting position C via the alignment mechanism 44; Thus, the cutter 422 can not only enter the through space 514 to ensure that the cutter 422 can truly cut the bobbin thread 60, but also can certainly interfere with the spool member 511. none. And, the movable drive source 411 of the movable mechanism 41 drives the movable arm 412 of the movable mechanism 41 to swing upward, and thus, the cutting drive source 421, the cutter 422 and the suction The three mechanisms 43 are away from the bobbin 51; When the cutter 422 leaves the through space 514 of the bobbin 51, in order to improve the effect of sucking the remaining bobbin thread 60 by the suction mechanism 43, the first operation module 311 1 The transmission member 3112 may drive the bobbin 51 to rotate; Accordingly, the bobbin 51 of the first bobbin module 501 shows an initial state S2 that is not wound with the bobbin thread 60, that is, the operation of removing the bobbin thread 60 is completed. .

See FIG. 15C. The movable arm 412 of the suction mechanism 43 assembled to the movable mechanism 41 is only for convenience of description, that is, the suction mechanism 43 may be assembled to the fixing frame 14 of the sewing machine body 10. have; Accordingly, when the movable arm 412 swings, the suction mechanism 43 does not swing as the movable arm 412. As shown in the drawing, the suction port 431 of the suction mechanism 43 is located under the bobbin 51, the appearance of the suction port 431 represents a funnel (funnel), whereby the cutter 422 When in the cutting position (C) to cut the bobbin thread 60, the suction mechanism 43 can accommodate the bobbin thread 60 that naturally falls after being cut by the cutter 422, and accordingly The thread 60 is removed from the bobbin 51 by the suction airflow A.

See FIG. 15D. In a preferred embodiment, the cutting transmission member 423 of the thread cutting mechanism 42 is connected to a pneumatic source (not shown in the drawing) capable of generating an airflow, and the cutting transmission member 423 has a cutter 422 A plurality of air blowing holes (423a) close to) are provided. Accordingly, when the cutter 422 is in the cutting position (C) to cut the bobbin thread 60, in order to prevent the cut bobbin thread 60 from being wound around the cutting transmission member 423, the pneumatic source Generates a blowing air flow (B) flowing out of the air blowing holes (423a).

Referring to FIG. 16A, after the bobbin thread 60 is removed, the work of winding the bobbin thread 60 is started. First, the first driving source 3111 of the first operation module 311 generates rotation power to drive the first driving belt pulley 3113a of the first interlocking module 3113 to rotate, which is the first The first belt 3113c of the interlocking module 3113 rotates the first transmission member 3112 about the motion axis L through the first driven belt pulley 3113b of the first interlocking module 3113. Therefore, the bobbin thread 60 inside the clamping space 3314 starts to rotate together with the first transmission member 3112, and accordingly, the bobbin 51 of the first bobbin module 501 is It rotates synchronously to bring 60 into the winding space 513 of the bobbin 51.

In the initial stage, the bobbin 51 of the first bobbin module 501 is wound with a bobbin thread 60. Since the outer diameter of the first winding portion 511a of the first bobbin module 501 is smaller than the outer diameter of the second winding portion 511b of the first bobbin module 501, the bobbin thread 60 is the first bobbin module To ensure that the through space 514 of 501 is covered, the bobbin thread 60 is first wound around the first winding portion 511a of the bobbin 51; Accordingly, the residual bobbin thread 60 on the bobbin 51 of the first bobbin module 51 also remains in the first winding portion 511a after the sewing operation, and thus the thread cutting mechanism 42 at the cutting position (C) ) Of the cutter 422 can truly cut the bobbin thread 60. In a preferred embodiment, in order to further ensure that the bobbin thread 60 is first wound around the first winding unit 511a in the initial stage of the winding operation, the regulating drive source 342 of the bobbin thread control mechanism 34 is It drives to swing the adjustment member 341 of the bobbin thread control mechanism 34, which causes the through hole 3412a of the adjustment member 341 to further restrict the bobbin thread 60 to the connecting plate 3112a. When the bobbin thread 60 is wound up to a specific number of times (for example, 10 or 20 times) on the first winding portion 511a, the adjustment driving source 342 passes the adjustment member 341 through the through hole 3412a. The bobbin thread 60 is driven so as not to limit its movement, so that the bobbin thread 60 is evenly wound around the spool member 511 of the bobbin 51. In addition, when the bobbin thread 60 is wound on the first winding portion 511a up to a specific number of times (eg, 10 or 20 times), the discharge driving sock 332 of the thread discharging mechanism 33 is also Of the blade 3112b (shown in FIG. 16F) so that the ejection lever 331 of the 33 is driven to swing, and thus, the pushing portion 3312 of the ejection lever 331 releases the bobbin thread 60. Pushing the lower end of the connecting portion 3112d, which causes the end of the bobbin thread 60 inside the clamping space 3314 to loosen and at the same time wound into the winding space 513. Immediately, the ejection driving source 332 drives the pushing portion 3312 to move away from the connecting plate 3112a, and thus, the blade 3112b connects the edge portion 3112c to the connecting plate through its own elastic force. To be brought into contact with (3112a); Subsequently, when the bobbin 51 of the first bobbin module 501 is wound with the bobbin thread 60 up to a preset number of times, the inside of the winding space 513 of the first bobbin module 501 is the bobbin thread 60 Is completely wound, and at this time, the first driving source 3111 of the first operation module 311 stops rotation.

See Fig. 16B. After stopping the winding of the bobbin thread 60, since the relative positional relationship between the bobbin thread 60 and the clamp module 323 cannot be determined, the regulating drive source 342 of the bobbin thread control mechanism 34 is It is necessary to drive the adjusting member 341 of the yarn control mechanism 34 to swing relative to the pivot shaft 3411, which means that the adjusting plate 3412 of the adjusting member 341 is connected to the yarn gripper 15 and the bobbin. 51) to come into contact with the bobbin thread 60 positioned between, and accordingly, the through hole 3412a of the adjustment plate 3412 is the bobbin thread 60 positioned between the thread gripper 15 and the bobbin 51 Is limited to close to the clamp module 323. Through this, it ensures that the clamp module 323 then clamps the bobbin thread 60 which is located between the thread gripper 15 and the bobbin 51. To achieve the above-described effect, another implementation procedure is to drive the adjustment drive source 342 to swing the adjustment member 341 before stopping winding the bobbin thread 60, which is the adjustment plate 3412 Make contact with the bobbin thread 60 between the thread gripper 15 and the bobbin 51; Accordingly, the bobbin thread 60 positioned between the thread gripper 15 and the bobbin 51 is limited to be close to the clamp module 323, which is the bobbin thread 60 finally wound around the bobbin 51 is clamped. To be on the path of movement of the module 323.

See Fig. 16C. The first movable jaw driving source 3211 of the first movement module 321 drives the first jaw transfer member 3212 of the first movement module 321 to extend outward, and the bobbin thread clamping mechanism 32 The clamp module 323 of the first jaw transmission member 3212, along the first path D1 (shown in Fig. 16D) crossing the motion axis L (shown in Fig. 16D), the first preparation position P1 (Fig. 16a) is driven to move to the clamping position P2, which means that the bobbin thread 60 between the bobbin 51 and the thread gripper 15 is located between the movable clamp 3231 and the fixed clamp 3232 Let it be. In this embodiment, during the movement of the clamp module 323 from the first preparation position P1 to the clamping position P2, the guide wheel 3244 of the avoiding unit 324 is applied to the holding force 3245a of the holding member 3245. ) Through a continuous contact with the curved guide rail 3242a of the assembly plate 3242, and thus, the guide wheel 3244 is curved from one end of the curved guide rail 3242a to the other of the guide rail 3242a. When moving to the end, the swing plate 3241 of the avoiding unit 324 drives the first moving module 321 and the clamp module 323 to swing in a counterclockwise path, which is the clamp module 323 In order to avoid the bobbin 51 of the 1 bobbin module 501, there are three parts (the first moving jaw driving source 3211, the first jaw transmission member 3212 and the clamp module 323 and the first bobbin module ( The relative position between the 501) is further changed. Through this, when moving to the clamping position P2 along the first path D1, the clamp module 323 passes through the avoiding unit 324 to the first bobbin module 501 ) Of the bobbin 51. When the clamp module 323 of the bobbin thread clamping mechanism 32 is in the clamping position P2, the stop pin 3231b of the movable clamp 3231 is the bobbin 51 It is possible to contact the bobbin thread 60 between the thread gripper 15. Through this, when the bobbin thread 60 is in a loose state, the stop pin 3231b is a movable clamp 3231 and a fixed clamp 3232 ) It is possible to limit the local length of the bobbin thread 60 through the space, and due to this, when the clamp module 323 clamps the bobbin thread 60, the relative positional relationship between the bobbin thread 60 and the clamp module 323 Then, the clamp drive source 3233 of the clamp module 323 drives to swing the movable clamp 3231 of the clamp module 323, which means that the movable clamp 3231 of the clamp module 323 Move it closer to the fixed clamp (3232), and The movable clamp 3231 and the fixed clamp 3232 at a position near the sea adjustment member 341 clamp the bobbin thread 60 positioned between the bobbin 51 and the thread gripper 15. At this time, the clamping block 3232a of the fixed clamp 3231 moves into the clamping groove 3231a, and thus, the clamping groove 3231a and the clamping block 3232a are in close contact, which means that the bobbin seal 60 In order to prevent separation from the clamping module 323, the clamping groove 3231a and the clamping block 3232a clamp the bobbin thread 60, and the clamping groove 3231a and the clamping block 3232a are combined with the bobbin thread. Let the localized length of (60) clamp. Here, the bobbin thread 60 is set as the source bobbin thread 62 assembled in the thread gripper 15 as well as the bobbin thread 61 wound between the bobbin 51 and the clamp module 323 Is divided into the rest of the parts.

See FIGS. 16E and 16F. The first movable jaw driving source 3211 of the first moving module 321 drives the first jaw transfer member 3212 of the first moving module 321 to move backward, and the bobbin thread clamping mechanism 32 The clamp module 323 of the is driven to return from the clamping position P2 to the first ready position P1 along the first path D1, which means that the source bobbin thread 62 of the first bobbin module 501 Pass under the bobbin 51. At this time, the ejection driving source 332 of the thread ejection mechanism 33 drives the ejection lever 331 of the yarn ejection mechanism 33 to swing, which means that the pushing portion 3312 of the ejection lever 331 is a blade The edge portion 3112c of the blade 3112b is connected so as to push the lower end of the connecting portion 3112d of 3112b, thereby allowing the clamping space 3314 to indicate an open state into which the bobbin thread 60 enters. It moves away from the plate 3112a. Subsequently, the first driving source 3111 of the first operation module 311 drives the first transmission member 3112 to rotate clockwise through the first interlocking module 3113, which is the source bobbin thread 62 ) To pass through the interior of the clamping space 3314. And, the ejection driving source 332 drives the ejection lever 331 to swing, which causes the pushing portion 3312 of the ejection lever 331 to move away from the lower end of the connection portion 3112d of the blade 3112b. ; Accordingly, so as to wait for the next operation of winding the bobbin thread 60, the blade 3112b uses its own elastic force, so that the edge portion 3112c of the blade 3112b and the connection plate 3112a are combined with the source bobbin thread 62. ) (Shown in Fig. 16F) to clamp. After that, the second movable jaw driving source 3221 of the second movement module 322 drives the second jaw transfer member 3222 of the clamp module 323 to make the first stage movement travel, and thus, the first 1 The moving module 323 and the clamp module 323 are both driven to move by the second jaw transmission member 3222, whereby the clamp module 323 is moved from the first preparation position P1 to the first path. It moves to the first guiding position P3 along the second path D2 intersecting with (D1); When the clamp module 323 is in the first guiding position P3, the source bobbin seal 62 will contact the edge portion 3112c of the blade 3112b. Subsequently, as shown in FIGS. 16G and 16H, the first driving source 3111 of the first moving module 311 moves the first transmission member 3112 through the first interlocking module 3113 to the motion shaft ( It is driven to rotate counterclockwise about L), which causes the blade 3112b to be driven to cut the source bobbin thread 62 by the first transmission member 3112. At this time, the end of the source bobbin thread 62 is clamped by the blade 3112b, while the end of the wound bobbin thread 61 is clamped by the clamp module 323. 16A to 16H, the bobbin case 52 is separated from the bobbin 51 in the axial direction for convenience of description. In fact, the relative distance between the bobbin case 52 and the bobbin 51 should be substantially represented as the separated state S1 of FIG. 15A. Further, in Fig. 16G, in order to clearly indicate the angular state of the blade 3112b, the bobbin 51 is moved out of the connecting plate 3112a.

In the above-described steps of FIGS. 16A to 16E, in order to prevent the clamp module 323 from moving along the first path D1, the clamp module 323 includes a connecting plate 3112a and a blade 3112b. Will interfere; The first operation module 311 can be driven to rotate the connection plate 3112a and the blade 3112b, which causes the blade 3112b to rotate at an angle to avoid the clamp module 323, but shown in the figure. Is not limited to the specified angle.

See Fig. 17A. After the cutting of the bobbin thread 60 is completed, the wound bobbin thread 61 starts to be installed on the bobbin case 52 of the first bobbin module 501. First, the third driving source 3131 of the third operation module 313 drives to move the third interlocking module 3133 away from the third transmission member 3132; The restoring force 3134a of the resetting member 3134 acts on the pressing block 3132a, which causes the third transmission member 3132 to move toward the third drive source 3131, thereby moving the third The transmission member 3132 allows the bobbin case 52 of the first bobbin module 501 to be assembled to the bobbin 51 of the first bobbin module 501; Accordingly, the bobbin case 52 of the first bobbin module 501 and the bobbin 51 of the first bobbin module 501 are converted from the separated state (S1) to an assembled state (S3) assembled to each other. At this time, the wound bobbin thread 61 contacts the open end 524 of the bobbin case 52, and the wound bobbin thread 61 is in a tensioned state.

See FIG. 17B. When the bobbin thread 60 with the deduction is in contact with the open end 524 of the bobbin case 52, the second driving source 3121 of the second operation module 312 is the second driving source 3121 of the second interlocking module 3123 It generates rotational power to drive the drive belt pulley 3123a to rotate, which means that the second transmission member 3122 connects the second transmission member 3122 to the second driven belt pulley of the second interlocking module 3123 ( 3123b) to drive to rotate about the axis of motion (L); When the second transmission member 3122 rotates, the synchronous protruding pillar 3142 of the synchronization module 314 cannot be moved due to the limitation of the synchronization groove 3141, and thus, the second transmission member 3122 is synchronized. Through the module 314, the third operation module 313 is driven to rotate, and thus the bobbin case 52 of the first bobbin module 501 rotates synchronously. As shown in the figure, the second driving source 3121 first drives the bobbin case 52 of the first bobbin module 501 to rotate clockwise through the second transmission member 3122, and then 2 driving source 3121 drives the bobbin case 52 of the first bobbin module 501 to rotate in a counterclockwise direction; Accordingly, the bobbin thread 61 in which the rotating bobbin case 52 is wound can be guided into the thread guiding slot 527 of the bobbin case 52, and the local length of the wound bobbin thread 61 is It is positioned between the case 52 and the clamping elastic piece 528 of the bobbin case 52.

See FIG. 17C. Next, the second movable jaw driving source 3221 of the second movement module 322 drives the second jaw transfer member 3222 of the clamp module 323 to make a second stage movement travel, which is the first Both the movement module 321 and the clamp module 323 are driven by the second transmission member 3222 to move in a direction away from the connection plate 3112a, and thus, the clamp module 323 ) And moves from the first guiding position P3 to the second preparation position P4 along the third path D3 parallel to ). As shown in FIG. 17D, during the moving process of the clamp module 323 toward the second preparation position P4, the first article transfer member 3212 of the first moving module 321 is of the avoiding unit 324. Contact with the roller 3242, which causes the swing plate 3241 of the avoiding unit 324 to swing, thereby separating the guide wheel 3244 of the avoiding unit 34 from the curved guide rail 3242A. Thus, the bobbin thread clamping mechanism 32 pulls the wound bobbin thread 61, which causes the wound bobbin thread 61 to be introduced into the guiding opening 528a of the clamping elastic piece 528, thereby clamping The bobbin thread 61 in which the elastic piece 528 is wound may be guided from the thread guiding slot 527 to the thread guiding hole 526.

See FIG. 17E. When the clamp module 323 is positioned in the second preparation position P4, the first movable jaw driving source 3211 of the first movable module 321 is the first jaw transfer member ( 3212 is driven again to extend outward, and thus, the first jaw transmission member 3212 moves the clamp module 323 to the second ready position along the fourth path D4 parallel to the first path D1. Drive to move from (P4) to the second guiding position (P5); During the moving process of the clamp module 323 toward the second guiding position P5, the wound bobbin thread 61 first contacts the hook arm 529 of the bobbin case 52, and then, the wound bobbin. The thread 61 pushes the elastic arm 530a of the thread blocking piece 530, which causes the elastic arm 530a to be deformed, and thus, the wound bobbin thread 61 is a thread hole of the hook arm 529 ( 529a) is guided into. Thus, the work of mounting the bobbin thread 61 wound with the bobbin case 52 is completed; The wound bobbin thread 61 is located inside the thread hole 529a, and the elastic arm 530a overlaps with the thread hole 529a because it is not pushed by the wound bobbin thread 61, which is an elastic arm 530a. ) To prevent separation of the wound bobbin thread 61 blocked by the thread hole 519a.

See FIG. 17F. The wound bobbin thread 61 is guided into the inside of the thread hole 529a of the hook arm 529, and the clamp drive source 3233 of the clamp module 323 holds the movable clamp 3231 of the clamp module 323. Drive to swing; Thus, the movable clamp 3231 is away from the fixed clamp 3232 of the clamp module 323, whereby the clamp module 323 releases the end of the wound bobbin thread 61. Finally, the clamp module 323 moves back from the second guiding position P5 to the first ready position P1 through the first moving module 321 and the second moving module 322, which is the clamp module Wait for 323 to attach the bobbin thread 60 to the bobbin case 52.

See Figure 18. In the second preferred embodiment, the difference from the first preferred embodiment is the assembly sequence between the first operation module 311, the second operation module 312, the third operation module 313 and the synchronization module 314. to be. As shown in the drawing, the second transmission member 3122 of the second operation module 312 is disposed to be movable through the first transmission member 3112 of the first operation module 311, and the second operation The second interlocking module 3123 of the module 312 is configured as a single hollow shaft, and the third transmission member 3132 is movably assembled on the outer periphery of the second interlocking module 3132 and the synchronization of the synchronization module 314 Assembled to the second transmission member 3122 through the protruding pillar 3142; The first transmission member 3112 and the third transmission member 3132 are respectively located on opposite sides of the second transmission member 3122. In addition, the third interlocking module 3133 of the second operation module 313 includes an interlocking rack 3133a and a third driving source 3131 capable of driving displacement of the second transmission member 3132 in the axial direction. ) Is provided with an interlocking gear 3133b assembled; The interlocking rack 3133a meshes with the interlocking gear 3133b. The synchronization groove 3141 of the synchronization module 314 is formed in the second interlocking module 3123, which makes the synchronization groove 3141 an elongated form, whereby the synchronization protruding pillar 3142 is removed. 3 The transmission member 3132, the second interlocking module 3123, and the second transmission member 3122 are disposed to penetrate simultaneously.

In this embodiment, when the second driving source 3121 of the second operation module 312 generates rotation power, the second driving source 3121 transfers the second transmission member 3122 to the first transmission member ( 3112). At this time, the synchronous protruding pillar 3142 of the synchronization module 314 will not be affected by the first transmission member 3112 to rotate, and the synchronization groove 3141 of the synchronization module 314 is the second transmission member. It rotates synchronously with (3122). In addition, the third driving source 3131 of the third operation module 313 generates rotation power, and the interlocking gear 3133b of the third interlocking module 3133 is an interlocking rack 3133a of the third interlocking module 3133. ) To move; Accordingly, the third transmission member 3132 moves along the motion axis L. Further, when the third transmission member 3132 moves, the synchronous protrusion pillar 3142 of the synchronization module 314 moves along the synchronization groove 3141 of the synchronization module 314, which is the third transmission member 3132 Is driven to move the entire second transmission member 3122 in the axial direction through the synchronization module 314.

See Figure 19. In the third preferred embodiment, the difference from the second preferred embodiment is that the bobbin module operation mechanism 31 does not have the synchronization module 314 and the third transmission member 3132 of the third operation module 313. will be; The second driving source 3121 configured as a plate member and assembled to the second operation module 312 prevents the third transmission member 3132 from being disposed coaxially on the operation axis L; When the third driving source 3131 of the third operation module 313 drives the third transmission member 3132 to move along the axial direction of the operation axis L, the entire second operation module 312 ( The second driving source 3121, the second transmission member 3122, and the second interlocking module 3123) move simultaneously along the motion axis L, and thus, the bobbin case 52 Move to separate from ). In this embodiment, the third transmission member 3132 may be directly connected to the third driving source 3131. However, the third transmission member 3132 may be connected to the third driving source 3131 through the third interlocking module 3133.

However, it is for convenience of description that the third transmission member 3132 is assembled to the second driving source 3121, that is, the third transmission member 3132 is the first driving source of the first operation module 311 ( 3111), whereby the entire first operation module 311 (including the first driving source 3111, the first transmission member 3112 and the first interlocking module 3113) is When the transmission member 3132 moves along the motion axis L through the third drive source 3131, it can simultaneously move along the motion axis L, which separates the bobbin 51 from the bobbin case 52. Let them move as much as possible.

In addition, in this embodiment, before the bobbin thread 60 is wound around the bobbin 51, the clamp module 323 of the bobbin thread clamping mechanism 32 can temporarily clamp the source bobbin thread 62, Thereafter, the ejection driving source 332 of the thread ejection mechanism 33 drives to swing the ejection lever 331 of the yarn ejection mechanism 33, which means that the pushing portion 3312 of the ejection lever 331 is a blade The lower end of the connecting portion 3112d of 3112b is pushed, whereby the edge portion 3112c of the blade 3112b is further removed from the connecting plate 3112a to allow the clamping space 3314 to remain open. Go away Next, the clamp module 323 is driven by the first moving module 321 and the second moving module 322 so that the source bobbin thread 62 is temporarily separated from the clamping space 3314. Therefore, in the process of removing the lower thread 60, the source lower thread 62 is temporarily separated from the clamping space 3314, so that the excess of the bobbin thread 60 during rotation of the first transmission member 3112, the thread gripper It can be prevented from being withdrawn from (15). Subsequently, after the removal of the bobbin thread 60 is completed, the first and second moving modules 321 and 322 drive the clamp module 323 to move, which causes the source bobbin thread 62 to move the clamping space 3314 ) To return to the inside. After that, the ejection driving source 332 drives the ejection lever 331 to swing, so that the pushing portion 3312 of the ejection lever 331 is away from the lower end of the connection portion 3112d of the blade 3112b. In this way, the blade 3112b causes the edge portion 3112c of the blade 3112 and the connection plate 3112a to collectively clamp the source bobbin thread 62 through its own elastic force.
