They are relative concepts and may change accordingly according to their different positions and different usage states. Therefore, these or other directional terms should not be interpreted as restrictive terms. In addition, the terms "first", "second", "third", etc. or similar expressions are only used for description and distinction purposes, and cannot be understood as indicating or implying the relative importance of the corresponding components.

[0036] The following is combined withFigure 1 - Appendix Figure 17 A further detailed description of the present application will be given below.

[0037] The embodiment of the present application discloses a silk thread connection mechanism for an automatic bobbin dropping of a texturing machine.

[0038] The following will be combined with the appendix Figure 1 - Appendix Figure 17 A further detailed description of the present application will be given below.

[0039] As Figure 1 and Figure 2 , the winding frame 1 is a prior art. The winding frame 1 is used to drive the reel 11 to rotate, so that the reel 11 winds and collects the raw silk. The winding frame 1 includes a plurality of mounting platforms 12. Each mounting platform 12 has a turning handle 13 and two turntables 14. The turning handle 13 can be held to lift or lower the mounting platform 12. The two turntables 14 are used to clamp both ends of the reel 11. The axial direction of the two turntables 14 is the left - right direction of the winding frame 1. When the reel 11 needs to be unloaded, first lift the mounting platform 12, then move the turning handle 13 to one side, one of the turntables 14 leaves one end of the reel 11, and then the reel 11 is disassembled and taken away from the end where the turntable 14 leaves.

[0040] The embodiment of the present application discloses a silk thread connection mechanism for an automatic bobbin dropping of a texturing machine.

[0041] Referring to Figure 1 and Figure 2 , a silk thread connection mechanism for an automatic bobbin dropping of a texturing machine includes a silk thread connection component and a winding frame 1 having a plurality of mounting platforms 12. The silk thread connection component is located in front of the winding frame 1 and is used to wind the silk thread onto an empty reel 11 on the winding frame 1 or break the thread of a full - material reel 11.

[0042] Referring to Figure 1 and Figure 2 , the silk thread connection component includes a moving platform 2 and a moving slide rail 21. The length direction of the moving slide rail 21 is parallel to the length direction of the winding frame 1. The moving platform 2 is slidably connected to the moving slide rail 21, and the moving platform 2 can move left and right relative to the winding frame 1.

[0043] Referring to Figures 1 - 3 , a gripper platform 3 is movably arranged on the moving platform 2. The gripper platform 3 can move back and forth relative to the winding frame 1. The gripper platform 3 is provided with a gripper arm 35. As the gripper platform 3 moves, the gripper arm 35 can feed or unload the reel 11 of the winding frame 1.

[0044] Referring to Figure 1 , Figure 2 , Figure 12 , Figure 13 , Figure 16 and Figure 17The clamping claw platform 3 is provided with a breaking slide rail 81, and the breaking slide rail 81 is located between the two clamping arms 35. The breaking slide rail 81 is slidably provided with a breaking wire platform 8.

[0045] Reference Figure 12 , Figure 13 , Figure 16 and Figure 17 The clamping platform 3 is also provided with a wire-breaking driving member 82, a driving wheel 83, a driven wheel 84 and a transmission belt 85. The wire-breaking driving member 82 is fixedly arranged on the clamping platform 3, and the driving wheel 83 is rotatably arranged on the clamping platform 3. The wire-breaking driving member 82 is a motor, and the driving end of the wire-breaking driving member 82 is connected to the driving wheel 83. The transmission belt 85 is sleeved on the driving wheel 83 and the driven wheel 84, and the wire-breaking platform 8 is also fixedly connected to the transmission belt 85. The wire-breaking slide rail 81 is parallel to the length direction of the winding frame 1. When the wire-breaking driving member 82 drives the driving wheel 83 to rotate, the wire-breaking platform 8 can move along the length direction of the wire-breaking slide rail 81, that is, move left and right relative to the winding frame 1.

[0046] Reference Figure 16 and Figure 17 , breaking position sensors 86 are respectively installed at both ends of the breaking slide rail 81. When the breaking wire platform 8 moves to one of the positions and is sensed by the breaking position sensor 86, the breaking wire driving member 82 will reverse, so that the breaking wire platform 8 moves toward the other breaking position sensor 86. Thus, the breaking wire platform 8 can reciprocate on the breaking slide rail 81.

[0047] Reference Figure 16 and Figure 17 The wire-breaking platform 8 has a toggling end 87 and a wire-breaking end 88 , wherein the toggling end 87 faces one of the clamping arms 35 , and the wire-breaking end 88 faces the other clamping arm 35 .

[0048] Reference Figure 16 and Figure 17 The toggling end 87 is mainly used to guide the silk thread. When the empty reel 11 is installed on the mounting platform 12, the end of the silk thread needs to be wound around the empty reel 11, and then the toggling end 87 of the wire breaking platform 8 is moved from the direction of the clamping arm 35 it is facing, so that the toggling end 87 can push the silk thread to be accommodated in a groove of the winding frame 1. The groove is used to reduce the problem of violent shaking of the silk thread when the reel 11 is wound around the silk thread. The groove is a prior art and is not shown in the figure.

[0049] Reference Figure 16 and Figure 17The wire cutting end 88 is provided with a blade, which is not shown in the figure. The blade is mainly used to cut the wire. When the full reel 11 needs to be removed from the mounting platform 12, the wire is first cut by moving the wire cutting end 88. After the wire is cut, the reel 11 will no longer collect and wind the wire. Then the reel 11 is removed from the winding frame 1 through the lifting and pressing mechanism 5 and the clamping claw platform 3.

[0050] Reference Figure 16 and Figure 17 After the empty reel 11 is mounted on the winding frame 1, the broken silk thread needs to be reconnected to the reel 11 by setting a suction mechanism 6 (such as Figure 10 ) to achieve reconnection of the wire to the reel 11.

[0051] Reference Figure 1 , Figure 2 , Figures 8 - 13 Specifically, the suction and delivery mechanism 6 includes a suction and delivery lifting and moving platform 61, a suction and delivery lifting and driving member 611, a suction and delivery front and rear moving platform 62, a suction and delivery front and rear driving member 621, a suction and delivery left and right moving platform 63, a first suction and delivery left and right driving member 64, a second suction and delivery left and right driving member 631, a push plate 65 and a suction and delivery silk thread gun 66; the suction and delivery lifting and moving platform 61 is slidably connected along the vertical direction of the clamping claw platform 3, the suction and delivery lifting and driving member 611 is fixedly arranged on the clamping claw platform 3, and the driving end of the suction and delivery lifting and driving member 611 is transmission-connected to the suction and delivery lifting and moving platform 61, so that the suction and delivery driving lifting and moving platform 61 can move up and down.

[0052] Reference Figure 9 and Figure 13 The suction and delivery front and back moving platform 62 is slidably arranged on the suction and delivery lifting and moving platform 61, and the suction and delivery front and back driving member 621 is fixedly arranged on the suction and delivery lifting and moving platform 61. The suction and delivery front and back driving member 621 is a motor, and the output shaft of the suction and delivery front and back driving member 621 is transmission connected with the suction and delivery front and back moving platform 62. The suction and delivery front and back driving member 621 can make the suction and delivery front and back moving platform 62 move forward and backward relative to the winding frame 1.

[0053] Reference Figure 9 and Figure 13 The suction and delivery left and right movable platform 63 is slidably connected to the suction and delivery front and rear movable platform 62, the second suction and delivery left and right driving member 631 is fixedly arranged on the suction and delivery front and rear movable platform 62, and the output end of the second suction and delivery left and right driving member 631 is transmission-connected with the suction and delivery left and right movable platform 63, which can drive the suction and delivery left and right movable platform 63 to move left and right relative to the winding frame 1.

[0054] Reference Figure 9 and Figure 13The first suction and delivery left and right driving member 64 is fixedly arranged on the suction and delivery left and right movable platform 63, and the push plate 65 is movably arranged on the suction and delivery left and right movable platform 63. The first suction and delivery left and right driving member 64 is a motor. The first suction and delivery left and right driving member 64 is transmission-connected with the push plate 65. The first suction and delivery left and right driving member 64 can drive the push plate 65 to move left and right relative to the winding frame 1. The transmission mode of the first suction and delivery left and right driving member 64 is screw rotation.

[0055] Reference Figure 9 and Figure 13 The suction wire gun 66 is arranged on the push plate 65, and the muzzle of the suction wire gun 66 faces the mounting platform 12 of the reel 11. As the push plate 65 moves left and right relative to the winding frame 1, the suction wire gun 66 can suck the wire, and when the wire needs to be wound onto the reel 11, the suction wire gun 66 can feed the wire, so that the wire contacts the reel 11, and the reel 11 keeps rotating under the action of the winding frame 1, so that the reel 11 can wind the wire.

[0056] Reference Figure 9 and Figure 13 Two suction position sensors 632 are arranged on the suction and delivery left and right movable platform 63, and the two suction and delivery position sensors 632 are located in the moving path of the push plate 65. When the second suction and delivery left and right driving member 631 drives the push plate 65 to move to one of the suction and delivery position sensors 632, the second suction and delivery left and right driving member 631 works in the reverse direction, allowing the push plate 65 to move toward the other suction and delivery position sensor 632. Through the reciprocating movement of the push plate 65, the suction and delivery silk thread gun 66 moves left and right relative to the winding frame 1, thereby facilitating the absorption of the broken silk thread onto the suction and delivery silk thread gun 66.

[0057] Specifically, after the empty reel 11 is placed in the winding frame 1, the broken wire is wound onto the reel 11 through the suction wire gun 66, and then the wire is moved by the moving end 87 of the wire-breaking table 8 so that the wire can be guided by the groove on the winding frame 1. When the reel 11 is full and needs to be removed, the wire is first cut by the wire-breaking end 88 of the wire-breaking table 8, and then the suction wire gun 66 sucks the broken wire. After the full reel 11 is unloaded by the clamping claw table 3 and the material changing mechanism 4, the new empty reel 11 will be installed on the winding frame 1, and the suction wire gun 66 will wind the sucked wire onto the reel 11, and this reciprocating cycle will be repeated.

[0058] Reference Figure 1 , Figure 2 , Figure 8 and Figure 9The clamping platform 3 includes a clamping base 31 and a plurality of clamping modules 32. The clamping modules 32 are stacked in sequence. The clamping base 31 is fixedly connected to the mobile platform 2. The clamping base 31 is connected to the clamping module 32 at the bottom through a screw drive. The remaining clamping modules 32 are stacked on the clamping module 32 at the bottom. When the clamping module 32 at the bottom moves back and forth toward the winding frame 1, the remaining clamping modules 32 move synchronously.

[0059] Reference Figures 8 - 11 The clamping module 32 includes a fixed seat 321 and a telescopic plate 322. The fixed seats 321 of adjacent clamping modules 32 are fixedly connected to each other, thereby ensuring the synchronous movement of multiple clamping modules 32. The telescopic plate 322 can move relative to the fixed seat 321, and the moving direction of the telescopic plate 322 is to move forward and backward relative to the winding frame 1.

[0060] Reference Figures 8 - 11 A telescopic driving member 323 is provided in the fixed seat 321 to drive the telescopic plate 322 to move toward the winding frame 1. The telescopic driving member 323 is a motor. The telescopic driving member 323 is in transmission connection with the telescopic plate 322. A telescopic rack 3231 is fixed to the telescopic plate 322. A telescopic gear 3232 is fixed to the driving shaft of the telescopic driving member 323. The telescopic gear 3232 is meshed with the telescopic rack 3231. As the telescopic driving member 323 is started, the telescopic gear 3232 can drive the telescopic rack 3231 to move the telescopic plate 322 relative to the fixed seat 321.

[0061] Reference Figures 8 - 11 , the telescopic plate 322 is the output end of the clamping module 32. The telescopic plate 322 is also provided with a giving way driving member 33 and a giving way plate 34, the giving way driving member 33 is a cylinder, the giving way driving member 33 is fixed to the telescopic plate 322, the driving end of the giving way driving member 33 is fixedly connected to the giving way plate 34, the giving way plate 34 is slidably connected to the telescopic plate 322, the giving way driving member 33 can drive the giving way plate 34, and the giving way plate 34 can move left and right relative to the winding frame 1.

[0062] Reference Figures 8 - 11 The clearance plate 34 is provided with a clamping arm 35 and a clamping drive 36, the clamping drive 36 is a cylinder, and each clearance plate 34 is provided with two pairs of clamping arms 35, the clamping arms 35 include an upper arm 351 (such as Figure 8 ) and lower arm 352 (such as Figure 8 ), the upper arm 351 and the lower arm 352 are both connected to the driving end of the clamping driving member 36, the clamping driving member 36 is fixed to the yielding plate 34, and can drive the upper arm 351 and the lower arm 352 to move relative to each other, that is, to make the upper arm 351 and the lower arm 352 move closer to or farther from each other in the vertical direction. The moving direction of the upper arm 351 and the lower arm 352 is to move up and down relative to the winding frame 1.

[0063] Reference Figures 7 - 11Under the action of the yielding driving member 33 , the yielding plate 34 can be driven to move, thereby causing the clamping arm 35 to move along the axial direction of the turntable 14 .

[0064] Reference Figure 1 , Figure 8 , Figure 9 , Figures 12 - 15 The clamping module 32 is also provided with a lifting and pressing mechanism 5, which can lift the mounting platform 12, and then move the handle 13 to one side, so that one of the two rotating disks 14 that originally clamp the reel 11 and is connected to the handle 13 is separated from one end of the reel 11. Then, the reel 11 is removed from the mounting platform 12 through the clamping claw platform 3.

[0065] Reference Figure 1 , Figure 8 , Figure 9 , Figures 12 - 15 Specifically, the clamping arm 35 is first controlled so that the distance between the upper arm 351 and the lower arm 352 is greater than the diameter of the reel 11. The clamping module 32 is first moved toward the winding frame 1 through the screw drive of the clamping claw base 31, and then the clamping arm 35 is driven to allow the upper arm 351 and the lower arm 352 to clamp the reel 11. After clamping, the yielding plate 34 is driven to move through the yielding driving member 33 so that the other end of the reel 11 also leaves the other turntable 14. Then the clamping arm 35 is moved backward. In this way, the reel 11 is removed from the mounting table 12. The reel 11 removed from the clamping arm 35 is then transferred to the standby rack 7 through the material changing mechanism 4.

[0066] Similarly, when it is necessary to install the empty reel 11 on the mounting platform 12, the empty reel originally on the standby rack 7 can be installed on the mounting platform 12 by using the material changing mechanism 4 and the clamping claw platform 3. The empty reel 11 continues to collect the silk thread.

[0067] After the lifting and pressing mechanism 5 lifts the mounting platform 12, the reel 11 will continue to rotate due to inertia. At this time, when the clamping arm 35 clamps the reel 11, the reel 11 will rotate relative to the clamping arm 35, and the contact position between the reel 11 and the clamping arm 35 will rub. Although this can stop the reel 11, friction will cause loss at the position where the reel 11 is clamped.

[0068] Reference Figure 11 and Figure 12 Therefore, rotating wheels are provided on both the upper arm 351 and the lower arm 352. A clamping groove 353 is provided on the upper arm 351 and the lower arm 352. The clamping groove 353 is arc-shaped, and the curvature of the arc is the same as the curvature of the reel 11. Part of the rotating wheel is located in the clamping groove 353. When the upper arm 351 and the lower arm 352 clamp the reel 11, the rotating wheel will abut against the reel 11, so that the multiple rotating wheels clamp the two ends of the reel 11. The rotating wheel is made of rubber.

[0069] Referring to Figure 11 and Figure 12 , there are three rotating wheels, which are distributed in a triangular shape. The three rotating wheels are respectively located at the front end 354, the middle end 355 and the tail end 356 of the clamping groove 353.

[0070] Referring to Figures 11 - 15 , the lifting and pressing mechanism 5 includes a lifting and pressing lifting table 51, a lifting and pressing lifting rail 511, a lifting and pressing front and rear moving table 52, a lifting and pressing front and rear moving rail 521, a lifting and pressing front and rear moving rack 522, a lifting and pressing front and rear moving driving member 523, a lifting and pressing left and right moving table 53, a lifting and pressing cylinder 54 (such as Figure 8 ), a lifting and pressing driving member 55 and a buffer cylinder 56; the lifting and pressing lifting rail 511 is fixedly arranged on the clamping module 32, the lifting and pressing lifting table 51 is slidably connected to the lifting and pressing lifting rail 511, the lifting and pressing front and rear moving rail 521 and the lifting and pressing front and rear moving rack 522 are fixedly connected to the lifting and pressing lifting table 51, the lifting and pressing front and rear moving table 52 is slidably connected to the lifting and pressing front and rear moving rail 521, the lifting and pressing front and rear moving table 52 is provided with a lifting and pressing front and rear moving driving member 523, the lifting and pressing front and rear moving driving member 523 is a motor, and the lifting and pressing front and rear moving driving member 523 is in transmission connection with the lifting and pressing front and rear moving rack 522. When the lifting and pressing front and rear moving driving member 523 is started, it can drive the lifting and pressing front and rear moving table 52 to move back and forth relative to the winding frame 1.

[0071] The lifting and pressing left and right moving table 53 is slidably arranged on the lifting and pressing front and rear moving table 52. The lifting and pressing front and rear moving table 52 is further provided with a lifting and pressing left and right moving driving member, which is not shown in the figure. The lifting and pressing left and right moving driving member can drive the lifting and pressing left and right moving table 53 to move left and right relative to the winding frame 1.

[0072] Referring to Figure 8 , Figure 9 , Figure 14 and Figure 15 , both the lifting and pressing cylinder 54 and the buffer cylinder 56 are arranged on the lifting and pressing left and right moving table 53. The lifting and pressing driving member 55 is fixed on the lifting and pressing left and right moving table 53. The lifting and pressing driving member 55 is a cylinder, and the output end of the lifting and pressing driving member 55 is connected to the lifting and pressing cylinder 54, which can drive the lifting and pressing cylinder 54 to move up and down. The opening of the lifting and pressing cylinder 54 faces the winding frame 1. Under the action of the lifting and pressing lifting table 51, the lifting and pressing front and rear moving table 52 and the lifting and pressing left and right moving table 53, the lifting and pressing cylinder 54 can be sleeved on the rotating handle 13 of the installation table 12, and then continue to control the lifting and pressing cylinder 54 to move up and down and left and right so as to be able to open the rotating handle 13.

[0073] Moreover, after the clamping arm 35 takes down the full - material reel 11 from the installation table 12, under the drive of the lifting and pressing mechanism 5, the buffer cylinder 56 can be in contact with the reel 11, so that the rotation speed of the reel 11 quickly slows down.

[0074] Referring toFigure 8 and Figure 9 The buffer cylinder 56 includes a fixed rod 561 and a sleeve 562. The fixed rod 561 is fixedly connected to the lifting and pressing left and right moving platform 53. The sleeve 562 is rotatably arranged on the fixed rod 561. The sleeve 562 is made of rubber.

[0075] Reference Figure 8 and Figure 9 A bearing is provided between the fixed rod 561 and the sleeve 562 , the inner ring of the bearing is connected to the fixed rod 561 , and the outer ring of the bearing is connected to the sleeve 562 .

[0076] Reference Figure 8 and Figure 9 The central axis of the buffer cylinder 56 is parallel to the central axis of the rotating wheel. After the rotating wheel clamps the reel 11, the buffer cylinder 56 can be well abutted against the reel 11.

[0077] Since there are multiple clamping modules 32, there are multiple lifting and pressing mechanisms 5, multiple give-way plates 34 and multiple give-way driving members 33; and the number of lifting and pressing mechanisms 5, multiple give-way plates 34 and multiple give-way driving members 33 corresponds to the number of clamping modules 32.

[0078] A synchronous belt 57 is connected between the output ends of the adjacent lifting and pressing front and back moving driving members 523. When the lifting and pressing front and back moving driving members 523 are working, the synchronous belt 57 can make the adjacent lifting and pressing front and back moving driving members 523 achieve the effect of synchronous operation.

[0079] Reference Figures 1 - 3 The wire connection mechanism comprises a preparation rack 7 , which can hold an empty reel 11 or a full reel 11 .

[0080] Reference Figures 1 - 3 A material changing mechanism 4 is movably arranged on the mobile platform 2 , and the material changing mechanism 4 is used to transfer the empty roll 11 from the standby rack 7 to the clamping arm 35 , or to transfer the full roll 11 on the clamping arm 35 to the standby rack 7 .

[0081] Reference Figures 1 - 3 The standby rack 7 has a plurality of empty drum slots 71 and material storage slots 72. The empty drum slots 71 are used to place empty rolls 11, and the material storage slots 72 are used to place full rolls 11. The empty drum slots 71 and the material storage slots 72 are both inclined, and the material changing mechanism 4 can take the empty roll 11 at the bottom of the empty drum slot 71. The staff can replenish the empty drum slot 71 with empty drums at any time, so that the bottom of the empty drum slot 71 always has an empty roll 11. The material changing slot can put the full roll 11 into the highest end of the material storage slot 72, and the full roll 11 in the material storage slot 72 rolls into the lowest end of the material storage slot 72 by itself. Keep the highest end of the material storage slot 72 empty. It is convenient for the material changing mechanism 4 to put a new full roll 11 into the material storage slot 72 every time.

[0082] Refer to Figures 2 - 4 , the material changing mechanism 4 includes a material changing base 41, a material changing rotating seat 42, and a material changing table 43; the material changing base 41 is slidably arranged on the moving platform 2 and moves back and forth relative to the winding rack 1; the material changing rotating seat 42 is arranged to be slidable on the material changing base 41 and moves left and right relative to the winding rack 1, and the material changing table 43 is rotatably arranged on the material changing rotating seat 42.

[0083] Refer to Figures 2 - 4 , through the combination of the material changing base 41 and the material changing rotating seat 42, the material changing table 43 can move back and forth and left and right relative to the jaw table 3. The material changing table 43 is provided with a chuck 44, and the chuck 44 can clamp the empty reel 11 or the full material reel 11. The material changing table 43 can rotate relative to the material changing rotating seat 42, so as to change the orientation of the chuck 44, so that the chuck 44 can face the clamping arm 35 or face the spare goods shelf 7.

[0084] Refer to Figures 3 - 5 , the material changing base 41 is provided with two material changing movement position sensors 411, the material changing rotating seat 42 is fixed with a material changing movement induction piece 412, and the two material changing movement position sensors 411 are located on the movement path of the material changing movement induction piece 412. One of the two material changing movement position sensors 411 is close to the jaw table 3, and the other is far from the jaw table 3.

[0085] Refer to Figures 3 - 5 , when the material changing movement induction piece 412 moves to the material changing movement position sensor 411 close to the jaw table 3, the chuck 44 is just in the process of putting the empty reel 11 on the clamping arm 35 or taking down the full material reel 11 on the clamping arm 35; when the material changing movement induction piece 412 moves to the material changing movement position sensor 411 far from the jaw table 3, it is necessary to change the orientation of the chuck 44 so that the chuck 44 faces the spare goods shelf 7 or the clamping arm 35 of the jaw table 3.

[0086] Refer to Figures 3 - 5 , the material changing table 43 is provided with a toothed disc 431, the material changing rotating seat 42 is provided with a material changing rotation driving part 421, and the output shaft of the material changing rotation driving part 421 is connected to the toothed disc 431 through gear transmission; the material changing rotation driving part 421 is a motor, and the material changing rotation driving part 421 can drive the toothed disc 431 to make the material changing table 43 rotate. Thus, the orientation of the chuck 44 is changed.

[0087] Refer to Figure 5 , the material changing rotating seat 42 is provided with a first material changing rotation position sensor 422 and a second material changing rotation position sensor 423, the material changing table 43 is fixedly provided with a material changing rotation induction piece 424, and the first material changing rotation position sensor 422 and the second material changing rotation position sensor 423 are located on the movement path of the material changing rotation induction piece 424.

[0088] Refer toFigures 3 - 5 After the refueling moving induction piece 412 moves to the refueling moving position sensor 411 away from the gripper table 3, the refueling table 43 rotates under the drive of the refueling rotation drive member 421. At this time, the refueling rotation induction piece 424 can move between the refueling first rotation position sensor 422 and the refueling second rotation position sensor 423.

[0089] Refer to Figures 3 - 5 When the refueling rotation induction piece 424 moves to the refueling first rotation position sensor 422, the chuck 44 is exactly facing the clamping arm 35 on the gripper table 3. When the refueling rotation induction piece 424 moves to the refueling second rotation position sensor 423, the chuck 44 is exactly facing the spare parts shelf 7.

[0090] Refer to Figure 5 The refueling table 43 is fixed with a limiting protrusion 432, and the gear disk 431 is provided with a limiting groove 433. The limiting protrusion 432 is located in the limiting groove 433.

[0091] Refer to Figure 5 The limiting groove 433 has two working ends. As the refueling table 43 rotates, the limiting protrusion 432 can move to one of the working ends or the other working end of the limiting groove 433, thereby limiting the rotation range of the refueling table 43.

[0092] Refer to Figure 5 and Figure 6 The refueling table 43 is further provided with a transverse rotation drive member 45, and the transverse rotation drive member 45 is in transmission connection with the chuck 44.

[0093] Specifically, the transverse rotation drive member 45 is a motor. The chuck 44 has a rotation shaft 441, and the transverse rotation drive member 45 is in transmission connection with the rotation shaft 441 in a belt drive form; the refueling table 43 is further provided with an arc-shaped anti-sway plate 442. The arc-shaped anti-sway plate 442 is internally provided with an elastic member, and the elastic member has a tendency to force the arc-shaped anti-sway plate 442 to move towards the rotation shaft 441. The arc surface of the arc-shaped anti-sway plate 442 abuts against the rotation shaft 441.

[0094] Refer to Figure 5 and Figure 6 The chuck 44 has a first chuck 444 and a second chuck 445. The transverse rotation drive member 45 can drive the chuck 44 to rotate, so that the first chuck 444 and the second chuck 445 rotate around the rotation shaft 441, and the clamping arm 35 (such as Figure 3)After taking the reel 11 from the winding rack 1, the central axes of the first jaw 444 and the second jaw 445 can be collinear with the central axis of the reel 11 between the upper arm 351 and the lower arm 352. After the central axis of the first jaw 444 or the second jaw 445 is collinear with the central axis of the reel 11, the material changing table 43 moves towards the clamping arm 35, so that the first jaw 444 and the second jaw 445 pick up the reel 11 on the clamping arm 35.

[0095] Refer to Figure 6 and Figure 7 , preferably, the first jaw 444 and the second jaw 445 rotate under the action of the lateral rotation driving member 45, so that the first jaw 444 can be vertically above the second jaw 445, or the second jaw 445 can be vertically above the first jaw 444. The arc-shaped anti-vibration plate 442 can improve the stability of the rotating shaft when the lateral rotation driving member 45 stops driving the chuck 44 to rotate, so that the first jaw 444 and the second jaw 445 do not shake relative to each other.

[0096] Refer to Figure 6 and Figure 7 , the lowest end of the empty reel slot 71 (such as Figure 1 ) is located on the moving path of the first jaw 444 or the second jaw 445, and the topmost end of the storage slot 72 is located on the moving path of the first jaw 444 or the second jaw 445.

[0097] Refer to Figure 6 and Figure 7 , the first jaw 444 and the second jaw 445 have the same structure, the same function and can be switched with each other. By rotating the chuck 44, after the full reel 11 on the clamping arm 35 is unloaded, the empty reel 11 can be installed on the clamping arm 35, shortening the interval between loading and unloading of the clamping arm 35, thereby improving the overall working efficiency.

[0098] Refer to Figures 1 - 7, specifically: Initially, the first jaw 444 is directly above the second jaw 445, the chuck 44 faces the stock shelf 7, the loading table 43 moves towards the stock shelf 7, and the first jaw 444 can pick up the reel 11 on the stock shelf 7. At this time, the second jaw 445 is in an empty state; after the clamping arm 35 picks up the full reel 11 of the winding frame 1, the chuck 44 will face the clamping arm 35, and the loading table 43 moves towards the clamping arm 35. The second jaw 445 picks up the full reel 11 on the clamping arm 35. Then the loading table 43 temporarily moves away from the clamping arm 35, and the chuck 44 rotates to exchange the positions of the first jaw 444 and the second jaw 445. At this time, the full reel 11 is above and the empty reel 11 is below. Then the loading table 43 moves towards the clamping arm 35 again to make the empty reel 11 enter the clamping arm 35. Then the loading table 43 moves towards the stock shelf 7 to install the full reel 11 onto the storage slot 72 of the stock shelf 7; at the same time, the clamping arm 35 feeds the empty reel 11 onto the mounting table 12.

[0099] Specific implementation method:

[0100] Referring to Figures 1 - 17 , the lifting and pressing assembly lifts the mounting table 12, the wire breaking table 8 cuts the wire, the suction and feeding wire gun 66 sucks the broken wire, the jaw table 3 removes the full reel 11 from the winding frame 1, then the loading mechanism 4 transfers the full reel 11 on the jaw table 3 to the stock shelf 7, and then the loading mechanism 4 transfers the empty reel 11 from the stock shelf 7 to the jaw table 3. The jaw table 3 installs the empty reel 11 onto the mounting table 12, the lifting and pressing assembly presses down the mounting table 12 to keep the reel 11 rotating, and the suction and feeding wire gun 66 winds the wire around the empty reel 11 to make the reel 11 in a state of winding and collecting the wire. Then the wire breaking table 8 deflects the wire, and the wire enters the groove of the winding frame 1 to make the wire in a stable feeding state.
