Description

Technical Field

[0001] This application relates to the field of garment sewing equipment technology, and more specifically, to a sewing method. Background Technology

[0002] A crew neck sewing machine can sew a crew neck to the neckline of a shirt. Before sewing, the crew neck and shirt need to be seamed and aligned. For example, the crew neck seam should be aligned 2 cm behind one of the seams on the shirt. Traditional crew neck sewing machines typically only seam the crew neck, requiring manual alignment of the seams on the shirt and neck. This is inefficient, costly, and prone to errors, affecting the sewing quality. Summary of the Invention

[0003] This application provides a sewing method.

[0004] The sewing method of this application is used in a round neck machine. The round neck machine includes a tensioning rotation module and a boning module. The tensioning rotation module includes a round neck tensioning rotation part, a garment tensioning rotation part, and an operating table. The sewing method includes controlling the round neck tensioning rotation part to tension and rotate a round neck fitted on the round neck tensioning rotation part and the operating table; controlling the boning module to perform boning on the round neck on the operating table; controlling the garment tensioning rotation part to tension and rotate a garment fitted on the garment tensioning rotation part and the operating table; and controlling the boning module to perform boning on the garment on the operating table and align the boning of the garment and the round neck.

[0005] Thus, by controlling the boning module to align the boning of the round neck and the garment on the operating table when the round neck is fitted onto the tensioning rotating module (including the round neck tensioning rotating part and the operating table), and by controlling the boning module to align the boning of the garment on the operating table when the garment is fitted onto the tensioning rotating module (including the garment tensioning rotating part and the operating table), the boning alignment of the round neck and the garment can be achieved. This eliminates the need for manual intervention in aligning the boning of the round neck and the garment, improving the efficiency of boning alignment, reducing costs, minimizing errors during the boning process, and improving sewing quality.

[0006] In some embodiments, the round neck tensioning rotating part includes a left inner guide roller and a right inner guide roller, the top tensioning rotating part includes a left outer guide roller and a right outer guide roller, the tensioning rotating module includes a pressure roller, a pressure roller motor, a right inner motor, and a right outer motor, the left inner guide roller is connected to the left outer guide roller via a one-way bearing, and controlling the tensioning and rotating of the round neck tensioning rotating part on the round neck sleeved on the round neck tensioning rotating part and the operating table includes controlling the pressure roller to press against the left outer guide roller; controlling the pressure roller motor to drive the pressure roller to rotate to drive the left outer guide roller and the left inner guide roller. The roller rotates along a first direction; the right inner motor is controlled to drive the right inner guide roller to rotate along the first direction; the control of the tensioning rotation of the garment tensioning rotation part and the garment sleeved on the garment tensioning rotation part and the operating table includes: controlling the pressure roller to press against the garment sleeved on the left outer guide roller; controlling the pressure roller to rotate to drive the left outer guide roller to rotate along a second direction, the second direction being opposite to the first direction so that the left inner guide roller remains stationary under the restriction of the one-way bearing; controlling the right outer motor to drive the right outer guide roller to rotate along the second direction.

[0007] Thus, when the round neck is being grooved, the pressure roller is controlled to press against the left outer guide roller and rotate, thereby driving the left inner guide roller to rotate along the first direction, and the right inner motor is controlled to drive the right inner guide roller to rotate along the first direction. When the pressure roller drives the left outer guide roller to rotate along the second direction to groove the garment, the left inner guide roller remains stationary under the constraint of the one-way bearing, so as to avoid the round neck grooving position changing after the garment is grooved and failing to align with the grooving position of the garment.

[0008] In some embodiments, the operating table includes an operating surface, a first limiting block, a second limiting block, a separator, and a separator motor. The first limiting block and the second limiting block are disposed on the operating surface and form a round neck limiting groove. The separator is slidably disposed above the second limiting block. After the boning module is controlled to perform boning on the round neck on the operating table, the sewing method includes controlling the separator motor to drive the separator to slide into the round neck limiting groove to separate the round neck and the top.

[0009] In this way, by controlling the separator to extend into the round neck limiting groove to separate the round neck and the top while the boning is being found in the top, the boning module will not detect the boning position of the round neck as the boning position of the top, thus ensuring the accuracy of the boning of the top, so that the boning positions of the round neck and the top can be aligned, and improving the sewing efficiency of the round neck and the top.

[0010] In some embodiments, controlling the bone-finding module to find the bone of the round neck on the operating table includes controlling the bone-finding module to find the bone of the round neck on the operating table surface; controlling the bone-finding module to find the bone of the upper garment and align the bone positions of the upper garment and the round neck on the operating table includes controlling the bone-finding module to find the bone of the upper garment and align the bone positions of the upper garment and the round neck on the partition.

[0011] In this way, by performing the upper garment bone finding on the partition, the bone finding module will not detect the bone position of the round neck as the bone position of the upper garment, thus ensuring the accuracy of the upper garment bone finding and enabling the round neck bone position and the upper garment bone position to be aligned.

[0012] In some embodiments, the round neck machine includes a correction module, and the sewing method includes controlling the correction module to correct the deviation of the garment while the boning module is boning the garment.

[0013] In this way, by controlling the correction module to correct the deviation of the top while it is being sewn, the correction module can correct the deviation of the top when it shifts on the worktable, thereby preventing the edges of the top and the round neck from being misaligned and avoiding affecting the subsequent sewing effect.

[0014] In some embodiments, the tensioning rotation module includes a secondary piece and a secondary piece cylinder, the correction module includes a garment correction sensor, the detection point of which is located at the edge of the round neck limiting groove, and after the boning module is controlled to guide the round neck on the operating table, the sewing method includes controlling the secondary piece cylinder to drive the secondary piece to slide into the round neck limiting groove.

[0015] In this way, by controlling the auxiliary piece cylinder to drive the auxiliary piece into the round neck limiting groove during the sewing process between the round neck and the top, the interference of the round neck on the top correction sensor can be blocked, so that the top can be correctly detected by the top correction sensor.

[0016] In some embodiments, the round neck machine includes a sewing module. After the boning module is controlled to perform boning on the garment and align the boning positions of the garment and the round neck on the operating table, the sewing method includes controlling the pressure roller to press against the left outer guide roller; controlling the pressure roller motor to drive the pressure roller to rotate so as to drive the left outer guide roller and the left inner guide roller to rotate along a first direction, while controlling the right inner motor and the right outer motor to drive the right inner guide roller and the right outer guide roller to rotate along the first direction respectively; and controlling the sewing module to sew the round neck and the garment.

[0017] Thus, by finding and aligning the seams of the round neck and the top, controlling the round neck tensioning rotating part to rotate the round neck and the top tensioning rotating part to rotate the top in the first direction, and controlling the sewing module to sew the rotating round neck and the top, it is possible to accurately sew the round neck onto the top.

[0018] In some embodiments, the round neck machine includes a correction module, and the sewing method includes controlling the correction module to correct the deviation of the top while the sewing module is sewing the round neck and the top.

[0019] Thus, by controlling the correction module to correct the deviation of the top while sewing the round neck and the top, the correction module can correct the deviation of the top when it shifts on the operating table, thereby improving the sewing quality of the round neck sewing to the top.

[0020] In some embodiments, the correction module includes a thread-cutting and material-removing sensor, the sewing module includes a thread-cutting device, and the sewing method includes, after the sewing module has finished sewing the round neck and the top, controlling the correction module to push the top to the detection point of the thread-cutting and material-removing sensor; controlling the sewing module to sew a diagonal line so that the sewing thread comes out of the top; and controlling the thread-cutting device to cut the sewing thread of the round neck and the top.

[0021] Thus, after the crew neck and top are sewn together, the control correction module pushes the top to the detection point of the thread-cutting and material-removing sensor, essentially pushing the garment outwards at an angle to sew a diagonal line until the edge of the top is sewn. Then, the control thread-cutting device cuts the thread. Compared to related technologies that rely on manual diagonal sewing, this method eliminates the need for human intervention, saving labor costs and improving the efficiency of sewing the crew neck onto the top.

[0022] In some embodiments, the round neck machine includes an anti-tangling module, the anti-tangling module includes a timing belt, and the sewing method includes driving the timing belt to cause the top, which rests on the timing belt, to rotate synchronously with the tensioning rotation module while the tensioning rotation module rotates the top.

[0023] Thus, when the tensioning rotation module drives the garment mounted on it to rotate, controlling the timing belt to rotate the garment synchronously prevents it from tangling on the tensioning rotation module. Compared to the current method of manually untangling tangled garments, this eliminates the need for constant manual monitoring, thereby reducing labor costs and improving sewing efficiency.

[0049] Please see Figure 1 , Figure 2 and Figure 3 The sewing method of this application embodiment is used in a round neck machine 100. The round neck machine 100 includes a tensioning rotation module 20 and a boning module 30. The tensioning rotation module 20 includes a round neck tensioning rotation part 21, a bodice tensioning rotation part 22, and an operating table 23. The sewing method includes...

[0050] Step 011: Control the round neck tensioning rotating part 21 to tension and rotate the round neck sleeved on the round neck tensioning rotating part 21 and the operating table 23;

[0051] Step 012: Control the bone-finding module 30 to perform bone-finding on the operating table 23;

[0052] Step 013: Control the tensioning rotating part 22 of the garment to tension and rotate the garment sleeved on the garment tensioning rotating part 22 and the operating table 23;

[0053] Step 014: Control the bone-finding module 30 to perform bone-finding on the upper garment and align the bone positions of the upper garment and the round neck on the operating table 23.

[0054] Thus, by controlling the boning module 30 to perform boning on the operating table 23 when the round neck is fitted onto the round neck tensioning rotating part 21 and the operating table 23 of the tensioning rotating module 20, and controlling the boning module 30 to perform boning on the operating table 23 when the upper garment is fitted onto the upper garment tensioning rotating part 22 and the operating table 23 of the tensioning rotating module 20, the boning module 30 can be controlled to perform boning on the operating table 23, thereby aligning the boning positions of the round neck and the upper garment. This eliminates the need for manual intervention in aligning the boning positions of the round neck and the upper garment, improving the efficiency of boning, reducing costs, minimizing errors during the boning process, and improving sewing quality.

[0055] The crew neck sewing machine 100 is used to sew a crew neck onto the neckline of a garment. By incorporating a tensioning rotation module 20 on the machine, and by rotating the crew neck and garment onto the tensioning rotation module 20, the crew neck can be sewn around the neckline of the garment. The crew neck sewing machine 100 also includes a controller 10, which can be a central processing unit (CPU) or a microcontroller unit (MCU), capable of issuing instructions to control the operation of various modules within the crew neck sewing machine 100.

[0056] Specifically, the tensioning and rotating module 20 includes a round neck tensioning and rotating part 21, a garment tensioning and rotating part 22, and an operating table 23. The round neck tensioning and rotating part 21 can be used to tension and rotate the round neck fitted thereon, the garment tensioning and rotating part 22 can be used to tension and rotate the garment fitted thereon, and the operating table 23 can be used to provide a place for sewing the round neck and the garment.

[0057] The round neck machine 100 also includes a bone-finding module 30, which can be used to find the bone positions of the round neck and the top, and determine whether the bone positions of the round neck and the top are aligned. It should be noted that the alignment of the bone positions of the round neck and the top can be that the bone positions of the round neck and the top are in relative positions, such as a 2 cm gap between the bone positions of the round neck and the top.

[0058] The bone-finding module 30 includes a mounting frame 31, a slide rail 32, a bone position detection component 33, and a double-stroke cylinder 334. The mounting frame 31 is mounted on the platform included in the round neck machine 100. The slide rail 32 is mounted on the mounting frame 31. The bone position detection component 33 is slidably mounted on the slide rail 32 and configured to slide along the guide of the slide rail 32. The double-stroke cylinder 334 is mounted on the mounting frame 31 and is used to drive the bone position detection component 33 to move along the guide of the slide rail 32. It is configured such that when the round neck is bone-finding, the double-stroke cylinder 334 drives the bone position detection component 33 to move a first stroke, and when the upper garment is bone-finding, the double-stroke cylinder 334 drives the bone position detection component 33 to move a second stroke.

[0059] The bone position detection component 33 includes a bone-finding sensor 331, two detection rollers 332, and two connecting rods 333. The two connecting rods 333 connect the two detection rollers 332 and are coupled to the bone-finding sensor 331. The two connecting rods 333 are used to transmit the height difference between the bone position and non-bone position of the round neck or top detected by the two detection rollers 332 to the bone-finding sensor 331. When the bone-finding sensor 331 detects that there is a height difference between the two detection rollers 332, it determines that the bone position of the round neck or top is in place.

[0060] When the controller 10 receives a signal that a round collar is fitted onto the collar tensioning rotating part 21, the controller 10 can control the collar tensioning rotating part 21 to tension and rotate the collar. After the collar is tensioned and rotated, the controller 10 can control the bone-finding module 30 to locate the collar bone on the operating table 23. For example, when the controller 10 drives the bone position detection component 33 to move in the first stroke, the two detection rollers 332 press against the rotating collar on the operating table 23, and when the bone-finding sensor 331 detects a height difference between the two detection rollers 332, it is determined that the collar bone position is in place.

[0061] When the controller 10 receives a signal that a garment is fitted onto the garment tensioning rotating part 22, the controller 10 can control the garment tensioning rotating part 22 to tension and rotate the garment. After the garment is tensioned and rotated, the controller 10 can control the bone-finding module 30 to locate the bone on the garment on the operating table 23. For example, when the controller 10 drives the bone position detection component 33 to move in the second stroke, the two detection rollers 332 press against the rotating garment on the operating table 23, and when the bone-finding sensor 331 detects a height difference between the two detection rollers 332, it is determined that the bone position of the garment is in place.

[0062] After the controller 10 determines the bone positions of the round neck and the top through the bone-finding module 30, it can determine that the bone positions of the round neck and the top are aligned.

[0063] Please see Figure 4 , Figure 5 and Figure 6In some embodiments, the round neck tensioning rotating part 21 includes a left inner guide roller 211 and a right inner guide roller 212, the upper garment tensioning rotating part 22 includes a left outer guide roller 221 and a right outer guide roller 222, the tensioning rotating module 20 includes a pressure roller 24, a pressure roller motor 25, a right inner motor 26, and a right outer motor 27, and the left inner guide roller 211 is connected to the left outer guide roller 221 through a one-way bearing. Step 011: Controlling the round neck tensioning rotating part 21 to tension and rotate the round neck sleeved on the round neck tensioning rotating part 21 and the operating table 23 includes:

[0064] Step 0111: Control the pressure roller 24 to press against the left outer guide roller 221;

[0065] Step 0112: Control the pressure roller motor 25 to drive the pressure roller 24 to rotate, thereby driving the left outer guide roller 221 and the left inner guide roller 211 to rotate along the first direction;

[0066] Step 0113: Control the right inner motor 26 to drive the right inner guide roller 212 to rotate along the first direction;

[0067] Step 013: Control the tensioning rotation of the garment tensioning rotating part 22. The garment sleeved on the garment tensioning rotating part 22 and the operating table 23 includes:

[0068] Step 0131: Control the pressure roller 24 to press against the upper garment fitted on the left outer guide roller 221;

[0069] Step 0132: Control the pressure roller 24 to rotate so as to drive the left outer guide roller 221 to rotate along the second direction. The second direction is opposite to the first direction so that the left inner guide roller 211 remains stationary under the constraint of the one-way bearing.

[0070] Step 0133: Control the right outer motor 27 to drive the right outer guide roller 222 to rotate along the second direction.

[0071] Thus, when the round neck is being grooved, the pressure roller 24 is controlled to press the left outer guide roller 221 to rotate and drive the left inner guide roller 211 to rotate along the first direction, and the right inner motor 26 is controlled to drive the right inner guide roller 212 to rotate along the first direction. When the pressure roller 24 drives the left outer guide roller 221 to rotate along the second direction to groove the upper garment, the left inner guide roller 211 remains stationary under the restriction of the one-way bearing, so as to avoid the round neck grooving position of the upper garment changing after grooving and failing to align with the upper garment grooving position.

[0072] Specifically, the round neck tensioning rotating part 21 includes a left inner guide roller 211 and a right inner guide roller 212, and the garment tensioning rotating part 22 includes a left outer guide roller 221 and a right outer guide roller 222. The left inner guide roller 211 and the left outer guide roller 221 are connected by a one-way bearing. The one-way bearing can be a type of bearing that can rotate freely in one direction and lock in the other. The left inner guide roller 211 is rotatably connected to the platform included in the round neck machine 100.

[0073] The tensioning rotation module 20 also includes a pressure roller 24, a pressure roller motor 25, a right inner motor 26, and a right outer motor 27. The pressure roller motor 25 can drive the pressure roller 24 to rotate in a first or second direction when the round neck is fitted onto the left inner guide roller 211 and the right inner guide roller 212, and the top is fitted onto the left outer guide roller 221 and the right outer guide roller 222, with the pressure roller 24 pressing against the top. This causes the round neck and the top to rotate. It should be noted that the first and second directions are opposite; for example, if the first direction is counterclockwise, the second direction is clockwise.

[0074] When the controller 10 receives information that the round collar is in a tensioned state on the tensioning rotation module 20, it can control the pressure roller 24 to move to the left outer guide roller 221 so that the pressure roller 24 presses against the left outer guide roller 221. Then the pressure roller motor 25 drives the pressure roller 24 to rotate, thereby driving the left outer guide roller 221 and the left inner guide roller 211 to rotate along the first direction. The right inner motor 26 can drive the right inner guide roller 212 to rotate along the first direction.

[0075] For example, when the first direction is counterclockwise, and the pressure roller 24 presses against the left outer guide roller 221 and is driven to rotate by the pressure roller motor 25, the pressure roller 24 can drive the left inner guide roller 211 and the left outer guide roller 221 to rotate counterclockwise, thereby enabling the pressure roller 24 to drive the round collar to rotate counterclockwise.

[0076] When the controller 10 receives information that the garment is in a tensioned state on the tensioning rotation module 20, it controls the pressure roller 24 to move towards the left outer guide roller 221 so that the pressure roller 24 presses against the garment on the left outer guide roller 221. Then, the pressure roller motor 25 drives the pressure roller 24 to rotate, thereby driving the left outer guide roller 221 to rotate in the second direction. The right outer motor 27 can also drive the right outer guide roller 222 to rotate in the second direction. The first and second directions are opposite, and the one-way bearing can restrict the left inner guide roller 211 from rotating in the second direction.

[0077] For example, when the second direction is clockwise, the pressure roller 24 presses against the left outer guide roller 221 on the garment and is driven to rotate by the pressure roller motor 25. This can drive the left outer guide roller 221 to rotate in a clockwise direction. Since the left inner guide roller 211 is restricted by the one-way bearing, it can remain stationary. Thus, the pressure roller 24 can drive the garment to rotate in a clockwise direction, while the round neck remains stationary.

[0078] Please see Figure 5 and Figure 7 In some embodiments, the operating table 23 includes an operating table surface 231, a first limiting block 232, a second limiting block 233, a separator 234, and a separator motor 235. The first limiting block 232 and the second limiting block 233 are disposed on the operating table surface 231 and form a round neck limiting groove 236. The separator 234 is slidably disposed above the second limiting block 233. After the bone-finding module 30 performs bone-finding on the operating table 23, the sewing method includes:

[0079] Step 015: Control the separator motor 235 to drive the separator 234 to slide into the round neck limiting groove 236 to separate the round neck and the top.

[0080] Thus, by controlling the separator 234 to extend into the round neck limiting groove 236 to separate the round neck and the top when the boning is being found in the top, the boning module 30 will not detect the boning position of the round neck as the boning position of the top, thereby ensuring the accuracy of the boning of the top, so that the boning positions of the round neck and the top can be aligned, and improving the sewing efficiency of the round neck and the top.

[0081] Specifically, the operating table 23 includes an operating surface 231, a first limiting block 232, and a second limiting block 233. The first limiting block 232 and the second limiting block 233 are arranged opposite to each other; that is, the first limiting block 232 is fixedly mounted on one side of the operating surface 231, and the second limiting block 233 is slidably mounted on the other side of the operating surface 231, thus forming a round neck limiting groove 236 between the first limiting block 232 and the second limiting block 233. Since round necks come in different sizes, the width of the round neck limiting groove 236 can be adjusted by changing the distance between the first limiting block 232 and the second limiting block 233 to accommodate different sizes of round necks.

[0082] For example, a through hole and a fixing block are formed on the operating table 231. The through hole is elliptical in shape and extends along the front and rear direction of the operating table 23. The fixing block fixes the second limiting block 233 by bolts passing through the through hole, so that the distance between the first limiting block 232 and the second limiting block 233 can be adjusted by adjusting the position of the second limiting block 233 on the through hole, so that the width of the round collar limiting groove 236 is adjusted to fit the size of the round collar.

[0083] The operating table 23 also includes a partition 234 and a partition motor 235. The partition 234 is generally rectangular in shape and its size is adapted to the length of the round collar limiting groove 236. The partition motor 235 can provide power for the movement of the partition 234. The partition 234 can be slidably mounted on the operating table 23 and can extend into or out of the round collar limiting groove 236 under the drive of the partition motor 235.

[0084] After receiving information that the round neck has completed bone locating, if the controller 10 needs to locate the bone of the upper garment, the controller 10 controls the separator motor 235 to drive the separator 234 to extend at least partially into the round neck limiting groove 236, thereby separating the round neck and the upper garment that are fitted on the round neck limiting groove 236, avoiding mistaking the bone location of the round neck for the bone location of the upper garment during bone locating, and avoiding failure of bone locating of the upper garment.

[0085] Please see Figure 2 and Figure 8 In some embodiments, step 012: controlling the bone-finding module 30 to locate the round neck bone on the operating table 23 includes:

[0086] Step 0121: Control the bone-finding module 30 to perform bone-finding on the operating table 231;

[0087] Step 014: Control the bone-finding module 30 to perform bone-finding on the garment and align the bone positions of the garment and the round neck on the operating table 23, including:

[0088] Step 0141: Control the bone-finding module 30 to perform bone-finding on the upper garment on the partition plate 234 and align the bone positions of the upper garment and the round neck.

[0089] Thus, by performing the upper garment bone finding on the separator 234, the bone finding module 30 will not detect the bone position of the round neck as the bone position of the upper garment, thereby ensuring the accuracy of the upper garment bone finding and enabling the round neck bone position and the upper garment bone position to be aligned.

[0090] Specifically, the operating table 23 includes an operating surface 231, a partition 234, and a partition motor 235. The bone-finding module 30 includes a bone-finding sensor 331. The bone-finding module 30 is positioned above the operating surface 231, and the detection point of the bone-finding sensor 331 is located on the operating surface 231. When the controller 10 receives a signal that a round collar is fitted on the operating surface 231, the controller 10 can control the round collar tensioning and rotating part 21 to tension and rotate the round collar. After the round collar is tensioned and rotated, the controller 10 can control the bone-finding module 30 to find the bone of the round collar on the operating surface 231. When the bone position sensor detects the bone position of the round collar, the controller 10 can control the round collar tensioning and rotating part 21 to stop working.

[0091] When the controller 10 receives a signal that a garment is fitted onto the partition 234, the controller 10 can control the garment tensioning and rotating part 22 to tension and rotate the garment. After the garment is tensioned and rotated, the controller 10 can control the bone-finding module 30 to find the bone on the partition 234. When the bone-finding sensor 331 detects the bone position of the garment, the controller 10 can control the garment tensioning and rotating part 22 to stop rotating.

[0092] Please see Figure 9 and Figure 10 In some embodiments, the round neck sewing machine 100 includes a correction module 40, and the sewing method includes:

[0093] Step 016: While the bone-finding module 30 is performing bone-finding on the upper garment, control the correction module 40 to correct the deviation of the upper garment.

[0094] Thus, by controlling the correction module 40 to correct the deviation of the top while it is being sewn, the correction module 40 can correct the deviation of the top when it is shifted on the operating table 23, thereby preventing the edges of the top and the round neck from being misaligned and avoiding affecting the subsequent sewing effect.

[0095] Specifically, the round neck machine 100 also includes a correction module 40. The correction module 40 includes a garment correction sensor 41, which can be a photoelectric sensor, ultrasonic sensor, etc. The detection point is located on the garment at the edge of the round neck limiting groove 236. When the separator 234 extends into the round neck limiting groove 236 and the garment is fitted onto the separator 234, the garment detection sensor can continuously detect whether the garment has shifted on the separator 234. If the garment shifts, i.e., when the garment correction sensor 41 cannot detect the garment at the detection point, the correction module 40 can correct the garment so that the edge of the garment is at the detection point of the garment correction sensor 41.

[0096] The correction module 40 includes correction rollers 43, a correction motor 44, a crank-slider assembly 45, and correction upper and lower cylinders 46. The round collar machine 100 includes a bracket (not shown) and a slide rail (not shown) mounted on the bracket. The bracket is mounted on the operating table 23, and the correction module 40 is slidably mounted on the slide rail. The correction rollers 43 extend axially along the front-rear direction of the operating table 23. The number of correction rollers 43 matches the number of crank-slider assemblies 45; for example, two sets of crank-slider assemblies 45 drive two correction rollers 43 respectively. The correction motor 44 includes a rotating shaft and is mounted on the bracket, used to drive the crank-slider assembly 45 to rotate. The crank-slider assembly 45 includes a crank (not shown) and a double-slider structure (not shown). The correction motor 44 drives the crank to rotate, thereby driving the double-slider mechanism to move. The double-slider mechanism can decompose the rotation of the crank into vertical and front-rear movements. The upper and lower correction cylinders 46 are mounted on the bracket and can drive the correction module 40 to move along the guide rail so that the two correction rollers 43 press against the top and push and pull the top along the front and back direction of the operating table 23 through the crank slider assembly 45 to perform correction.

[0097] If the edge of the garment deviates from the detection point of the garment correction sensor 41 during the process of locating the bone of the garment, the controller 10 can control the correction motor 44 to drive the two correction rollers 43 to move back and forth, so as to push the edge of the garment to the detection point of the garment correction sensor 41.

[0098] Please see Figure 5 and Figure 11 In some embodiments, the tensioning rotation module 20 includes a secondary piece 28 and a secondary piece cylinder 29, and the correction module 40 includes a garment correction sensor 41. The detection point of the garment correction sensor 41 is located at the edge of the round neck limiting groove 236. After the control boning module 30 performs boning on the operating table 23, the sewing method includes:

[0099] Step 017: Control the sub-piece cylinder 29 to drive the sub-piece 28 to slide into the round collar limiting groove 236.

[0100] Thus, by controlling the auxiliary piece cylinder 29 to drive the auxiliary piece 28 into the round neck limiting groove 236 during the sewing process between the round neck and the top, the interference of the round neck on the top correction sensor 41 can be blocked, so that the top can be correctly detected by the top correction sensor 41.

[0101] In order to ensure that the edge of the garment is not interfered with by the round neck during the detection process of the garment correction sensor 41, a separator component needs to be set at the detection point of the garment correction sensor 41.

[0102] Specifically, the separating component includes a secondary piece 28 and a secondary piece cylinder 29. The secondary piece 28 is disposed on the first limiting block 232 and can slide on the first limiting block 232 under the drive of the secondary piece cylinder 29. After the control bone-finding module 30 performs bone-finding on the round neck on the operating table 23, the controller 10 needs to control the secondary piece cylinder 29 to drive the secondary piece 28 to the blocking position, that is, control the secondary piece 28 to extend into the round neck limiting groove 236 to block the round neck located at the detection point of the upper garment correction sensor 41. Before the completion of sewing by a preset number of stitches (such as 30, 40, or 50 stitches), the controller 10 needs to control the secondary piece cylinder 29 to drive the secondary piece 28 to the avoidance position, that is, control the secondary piece 28 to exit the round neck limiting groove 236 and return to the first limiting block 232.

[0103] Please see Figure 12 and Figure 13 In some embodiments, the round neck machine 100 includes a sewing module 50. After the boning module 30 is controlled to perform boning on the garment and align the boning positions of the garment and the round neck on the operating table 23, the sewing method includes:

[0104] Step 018: Control the pressure roller 24 to press against the left outer guide roller 221;

[0105] Step 019: Control the pressure roller motor 25 to drive the pressure roller 24 to rotate so as to drive the left outer guide roller 221 and the left inner guide roller 211 to rotate along the first direction. At the same time, control the right inner motor 26 and the right outer motor 27 to drive the right inner guide roller 212 and the right outer guide roller 222 to rotate along the first direction, respectively.

[0106] Step 020: Control the sewing module 50 to sew the round neck and top.

[0107] Thus, by finding and aligning the seams of the round neck and the top, controlling the round neck tensioning rotating part 21 to rotate along the first direction and the top tensioning rotating part 22 to rotate along the first direction, and controlling the sewing module 50 to sew the rotating round neck and the top, one circle of the round neck can be accurately sewn onto the top.

[0108] Specifically, the round neck machine 100 includes a sewing module 50, which can be used to sew the round neck onto the neckline of a garment. The sewing module 50 also includes a presser foot 51 and a presser foot cylinder 52, which are located above the operating table 23. The presser foot 51, driven by the presser foot cylinder 52, can press the round neck and the garment together.

[0109] Before the round neck and top are fitted onto the tensioning rotating module 20, the presser foot cylinder 52 controls the presser foot 51 to lift, thus allowing the round neck and top to be fitted onto the tensioning rotating module 20. After the top is aligned with the seams on the operating table 23, the presser foot cylinder 52 controls the presser foot 51 to press against the round neck and top. The controller 10 controls the pressure roller 24 to press against the left outer guide roller 221. Then, the pressure roller motor 25 drives the pressure roller 24 to rotate, thereby driving the left outer guide roller 221 and the left inner guide roller 211 to rotate along the first direction. At the same time, the controller 10 can control the right inner motor 26 to drive the right inner guide roller 212 to rotate along the first direction, and control the right outer motor 27 to drive the right outer guide roller 222 to rotate along the first direction. During the rotation of the round neck and top, the controller 10 can control the sewing module 50 to sew the round neck and top rotating along the first direction.

[0110] Please see Figure 14 In some embodiments, the round neck sewing machine 100 includes a correction module 40, and the sewing method includes:

[0111] Step 021: While the sewing module 50 is sewing the round neck and the top, control the correction module 40 to correct the top's deviation.

[0112] Thus, by controlling the correction module 40 to correct the deviation of the top while sewing the round neck and the top, the correction module 40 can correct the deviation of the top when it shifts on the operating table 23, thereby improving the sewing quality of the round neck sewing to the top.

[0113] Specifically, after the crew neck and the bodice are aligned, the crew neck tensioning rotating part 21 and the bodice tensioning rotating part 22 can rotate the crew neck and the bodice respectively, so that the sewing module 50 can sew the crew neck onto the bodice. During the sewing process, the controller 10 can control the bodice correction sensor 41 to constantly detect whether the bodice has shifted on the separator 234. If the bodice has shifted, that is, if the bodice correction sensor 41 cannot detect the bodice at the detection point, the controller 10 can control the correction module 40 to correct the bodice so that the bodice is at the detection point of the bodice correction sensor 41, thereby preventing the crew neck from not being sewn onto the bodice or from being sewn at a position other than the preset position.

[0114] Please see Figure 5 and Figure 15 In some embodiments, the correction module 40 includes a thread-cutting and material-removing sensor 42, the sewing module 50 includes a thread-cutting component, and the sewing method includes:

[0115] Step 022: After the sewing module 50 has finished sewing the round neck and the top, control the correction module 40 to push the top to the detection point of the thread cut and material ejection sensor 42;

[0116] Step 023: Control the sewing module 50 to sew a diagonal line, so that the sewing thread comes out of the garment;

[0117] Step 024: Control the thread cutter to cut and sew the stitching for the round neck and top.

[0118] Thus, after the crew neck and top are sewn together, the control correction module 40 pushes the top to the detection point of the thread-cutting and material-removing sensor 42, essentially pushing the garment outwards at an angle to perform diagonal sewing until the edge of the top is sewn. Then, the control thread-cutting device cuts the sewing thread. Therefore, compared to related technologies where diagonal sewing is done manually, no manual intervention is required during the sewing process, saving labor costs and improving the efficiency of sewing the crew neck onto the top.

[0119] Specifically, the correction module 40 also includes a thread-cutting and material-removing sensor 42. This sensor 42 can be a photoelectric sensor, ultrasonic sensor, etc., with the detection point located on the operating table 23 and near the edge of the second limit block 233. The thread-cutting and material-removing sensor 42 can detect whether the edge of the garment is at the detection point when the garment and round neck are finished being sewn and the thread is about to be cut.

[0120] The sewing module 50 includes a sewing needle (not shown) and a thread cutter (not shown). The sewing needle is used to sew the round neck and the top. The thread cutter is positioned along the direction of rotation of the top and is used to cut the sewing thread after the diagonal stitching of the round neck and the top is completed. It should be noted that the sewing needle and the thread cutter are driven by the sewing module 50 simultaneously. After the correction module 40 pushes the top to the detection point of the thread cutter and material ejection sensor 42, the controller 10 can control the sewing module 50 to sew diagonal stitches on the round neck and the top so that the sewing thread comes out of the top.

[0121] After the sewing module 50 finishes sewing the round neck and the top, the controller 10 can control the correction module 40 to push the edge of the top to the detection point of the thread cut and material ejection sensor 42. After the top is sewn at the sewing needle position, the tensioning rotation module 20 stops rotating the top and moves the top on the left outer guide roller 221 toward the operating table 23, thereby changing the top from a tensioned state to a relaxed state. During this process, the sewing needle of the sewing module 50 continues to sew, so that the sewing thread is attracted to the position of the thread cutter and cut by the thread cutter.

[0122] Please see Figure 16 and Figure 17 In some embodiments, the round neck sewing machine 100 includes an anti-tangling module 60, which includes a timing belt 62, and the sewing method includes:

[0123] Step 025: While the tensioning rotation module 20 is rotating the top, the driving synchronous belt 62 causes the top, which is supported on the synchronous belt 62, to rotate synchronously with the tensioning rotation module 20.

[0124] Thus, when the tensioning rotation module 20 drives the garment fitted on it to rotate, the timing belt 62 controls the garment to rotate synchronously, preventing the garment from getting tangled on the tensioning rotation module 20. Compared to the current method of manually untangling tangled garments, this eliminates the need for constant manual monitoring, thereby reducing labor costs and improving sewing efficiency.

[0125] Specifically, during the sewing process on the tensioning rotating module 20, only the neckline of the garment is powered, while the rest of the garment will become tangled due to lack of power. Therefore, an anti-tangling module 60 is provided on the round neck sewing machine 100. The anti-tangling module 60 includes a fixing frame 61, a timing belt 62, and an anti-tangling motor 63. The fixing frame 61 is positioned in the direction perpendicular to the rotation direction of the tensioning rotating module 20 and is located close to the tensioning rotating module 20, so that the hem of the garment can be supported on the timing belt 62.

[0126] The timing belt 62 is rotatably mounted on the fixed frame 61. The timing belt 62 can be a round belt. The hem of the top can rest on the timing belt 62, and when the timing belt 62 rotates, the timing belt 62 can drive the top to rotate together.

[0127] The anti-winding motor 63 is mounted on one end of the fixed frame 61, and the anti-winding motor 63 can be rotatably connected to the synchronous belt 62.

[0128] When the controller 10 receives a signal from the tensioning rotation module 20 to rotate the collar of the shirt, it can control the anti-tangling motor 63 to drive the synchronous belt 62 to rotate, so that the synchronous belt 62 can drive the hem of the shirt supported on it to rotate together, thereby preventing the shirt from getting tangled.
