Description

Technical Field

[0001] This application relates to the field of garment sewing equipment technology, and more specifically, to a guide roller, a tensioning rotation module, a boning device, and a round neck machine. Background Technology

[0002] A crew neck sewing machine sews a crew neck to the neckline of a garment. During sewing, the crew neck and the garment need to be placed on guide rollers for seam alignment. However, when aligning the seam of the crew neck to the seam of the garment, the crew neck must remain stationary. Therefore, the guide rollers need to be able to drive the crew neck and the garment to rotate independently. Related technologies typically use two sets of drive components to rotate the guide rollers separately for the crew neck and the garment. However, this increases the number of parts in the crew neck machine, leading to increased costs, a more complex structure, and a larger size. Summary of the Invention

[0003] This application provides a guide roller, a tensioning rotation module, a bone-finding device, and a round collar machine.

[0004] The guide roller in this embodiment includes a one-way bearing, a first inner guide roller, a first outer guide roller, a pressure roller, and a first drive assembly. The first inner guide roller is rotatably connected to the platform via the one-way bearing and is used to fit a round neck. The first outer guide roller is coaxially rotatably connected to the first inner guide roller via the one-way bearing and is used to fit a top. The pressure roller is used to press against the top. The first drive assembly is used to drive the pressure roller to rotate along a first direction or a second direction. When the pressure roller rotates along the first direction, it drives the first inner guide roller and the first outer guide roller to rotate along the second direction. When the pressure roller rotates along the second direction, it drives the first outer guide roller to rotate along the first direction, while the first inner guide roller remains stationary due to the constraint of the one-way bearing. The first direction and the second direction are opposite.

[0005] Thus, only one drive assembly is used to drive the first inner guide roller to rotate along the second direction to align the neckline. While the pressure roller drives the first outer guide roller to rotate along the first direction to align the garment, the first inner guide roller remains stationary to prevent changes in the neckline's alignment after aligning, thus ensuring it matches the garment's aligning position. Therefore, compared to related neckline machines, only one drive assembly is needed to achieve both synchronous and asynchronous movement of the guide rollers, reducing the number of parts, manufacturing costs, and floor space.

[0006] In some embodiments, the round neck machine includes a first tensioning rotation module, the first tensioning rotation module including a first mounting plate, a first round neck limiting groove formed between the first outer guide roller and the first mounting plate, the first outer guide roller being configured to be axially adjustable to adjust the width of the first round neck limiting groove.

[0007] Thus, by forming a first round collar limiting groove between the first mounting plate and the first outer guide roller included in the first tensioning rotation module, the round collar can be fitted onto the guide roller, and the width of the first round collar limiting groove can be adjusted by adjusting the axial position of the first outer guide roller, so that the first round collar limiting groove can adapt to round collars of different sizes.

[0008] In some embodiments, the round collar machine includes a first tensioning rotation module, which includes a base, a second mounting plate, and a second drive assembly. The second mounting plate is slidably disposed on the base, and the pressure roller is rotatably disposed on the second mounting plate. The second drive assembly is used to drive the second mounting plate to slide, thereby causing the pressure roller to press against or move away from the guide roller.

[0009] Thus, by setting the pressure roller on the second mounting plate included in the first tensioning rotation module, and by driving the second mounting plate to slide through the second drive assembly so that the pressure roller presses against or moves away from the guide roller, the second mounting plate that fixes the pressure roller can be reused, and the pressure roller can be conveniently controlled to press against or move away from the guide roller.

[0010] In some embodiments, the round neck machine includes a second tensioning rotation module, which includes a second guide roller. The second guide roller includes a second inner guide roller, a second outer guide roller, a third drive assembly, and a fourth drive assembly. The second inner guide roller is rotatably connected to the platform and is used to fit the round neck. The second outer guide roller is rotatably connected to the second inner guide roller and is used to fit the top. The third drive assembly is used to drive the second outer guide roller to rotate, and the fourth drive assembly is used to drive the second inner guide roller to rotate.

[0011] Thus, by placing the top and round neck on the second outer guide roller and the second inner guide roller included in the second tensioning rotation module, and driving them respectively by the third drive motor and the fourth drive motor, they can cooperate with the first outer guide roller and the first inner guide roller to drive the round neck and top to rotate for sewing.

[0012] In some embodiments, a second round collar limiting groove is formed between the second outer guide roller and the second inner guide roller, and the second outer guide roller is configured to be axially adjustable to adjust the width of the second round collar limiting groove.

[0013] Thus, by forming a second round collar limiting groove between the second inner guide roller and the second outer guide roller included in the second tensioning rotation module, the round collar can be fitted onto the second guide roller, and the width of the second round collar limiting groove can be adjusted by adjusting the axial position of the second outer guide roller, so that the second round collar limiting groove can adapt to round collars of different sizes.

[0014] In some embodiments, the round neck machine includes a first tensioning rotation module, which includes a base, a first mounting plate, and a fifth drive assembly. The first mounting plate is slidably disposed on the base, and the guide roller is rotatably disposed on the first mounting plate. The fifth drive assembly is used to drive the first mounting plate to slide, thereby causing the guide roller to move away from the second guide roller to tension the round neck and the top.

[0015] Thus, by setting the guide roller on the first mounting plate, and the first mounting plate being able to slide on the base driven by the fifth drive assembly, the distance between the guide roller and the second guide roller can be adjusted, thereby allowing the round neck and the top to be tensioned.

[0016] In some embodiments, the round neck machine includes an operating table disposed on the platform and located between the guide roller and the second guide roller. The operating table includes an operating surface, a first limiting block disposed on the operating surface, and a second limiting block slidably disposed on the operating surface. The first limiting block and the second limiting block form a third round neck limiting groove.

[0017] Thus, by setting a first limiting block and a second limiting block on the table surface of the operating table, and forming a third round collar limiting groove between the first limiting block and the second limiting block, different sizes of round collars can be adapted by adjusting the distance between the first limiting block and the second limiting block, and the round collar can be limited by the third round collar limiting groove to prevent the round collar from shifting during rotation.

[0018] The tensioning rotation module of this application includes a first tensioning rotation module, a second tensioning rotation module, and a guide roller as described in any of the above embodiments.

[0019] The bone-finding device of this application includes the tensioning rotation module and the bone-finding sensor described in any of the above claims. The bone-finding sensor performs bone-finding on the round neck when the pressure roller rotates along the first direction, and performs bone-finding on the upper garment when the pressure roller rotates along the second direction.

[0020] Thus, when the pressure roller controls the rotation of the round neck along the first direction, the bone position detector can quickly determine the bone position of the round neck by detecting the round neck. Alternatively, when the pressure roller controls the rotation of the garment along the second direction, the bone position detector can quickly determine the bone position of the garment by detecting the garment, thereby improving the efficiency of finding the bone positions of the round neck and garment.

[0021] The round neck machine of this application includes a rotating module, a bone-finding device, and the guide roller described in any of the above embodiments.

[0030] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the embodiments of this application, and should not be construed as limiting the embodiments of this application.

[0031] In the description of this application, it should be understood that the terms "thickness," "upper," "top," "bottom," "inner," "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined as "first" or "second" may explicitly or implicitly include one or more features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0032] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linkage" should be interpreted broadly. In one example, they can refer to a fixed connection, a detachable connection, or an integral connection. They can refer to a mechanical connection, an electrical connection, or a connection that allows communication between the components. They can refer to a direct connection or an indirect connection through an intermediate medium, and they can refer to the internal communication between two components or the interaction between two components.

[0033] In embodiments of this application, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

[0034] Please see Figure 1The guide roller 211 in this embodiment includes a one-way bearing 2111, a first inner guide roller 2113, a first outer guide roller 2112, a pressure roller 2114, and a first drive assembly 2115. The first inner guide roller 2113 is rotatably connected to the platform 10 via the one-way bearing 2111 and is used to fit a round neck. The first outer guide roller 2112 is coaxially rotatably connected to the first inner guide roller 2113 via the one-way bearing 2111 and is used to fit a top. The pressure roller 2114 is used to press down on the top. The first drive assembly 2115 is used to drive the pressure roller 2114 to rotate in a first direction or a second direction. When the pressure roller 2114 rotates in the first direction, it drives the first inner guide roller 2113 and the first outer guide roller 2112 to rotate in the second direction. When the pressure roller 2114 rotates in the second direction, it drives the first outer guide roller 2112 to rotate in the first direction, while the first inner guide roller 2113 remains stationary due to the restriction of the one-way bearing 2111. The first direction and the second direction are opposite.

[0035] In this way, only one drive assembly is needed to drive the first inner guide roller 2113 to rotate along the second direction to align the round neckline. While the pressure roller 2114 drives the first outer guide roller 2112 to rotate along the first direction to align the garment, the first inner guide roller 2113 remains stationary to prevent changes in the neckline alignment after aligning, thus ensuring it is aligned with the garment's seams. Therefore, only one drive assembly is needed to achieve both simultaneous and asynchronous movement of the guide rollers 211, reducing the number of parts, manufacturing costs, and floor space required.

[0036] The round neck machine 100 is a device used to sew a round neck onto the neckline of a shirt. By setting a guide roller 211 on the round neck machine 100 and rotating the round neck and shirt on the guide roller 211, the round neck can be sewn onto the neckline of the shirt.

[0037] Specifically, the guide roller 211 includes a one-way bearing 2111, a first inner guide roller 2113, a first outer guide roller 2112, a pressure roller 2114, and a first drive assembly 2115. The one-way bearing 2111 can be a type of bearing that can rotate freely in one direction and lock in the other. One end of the one-way bearing 2111 can be rotatably connected to the platform 10 included in the round collar machine 100. The first inner guide roller 2113 is sleeved on the one-way bearing 2111 and can rotate relative to the platform 10 as the one-way bearing 2111 rotates. The round collar can be sleeved on the first inner guide roller 2113.

[0038] The first outer guide roller 2112 is coaxially sleeved on the first inner guide roller 2113 and can be rotatably connected to the first inner guide roller 2113. The first outer guide roller 2112 can be used to cover the top.

[0039] The first drive assembly 2115 can be a drive motor, drive cylinder, etc., which can drive the pressure roller 2114 to rotate along the first direction or the second direction when the round neck is sleeved on the first inner guide roller 2113, the top is sleeved on the first outer guide roller 2112, and the pressure roller 2114 is pressing against the top, thereby driving the round neck and the top to rotate. It should be noted that the first direction and the second direction are opposite. For example, if the first direction is clockwise, the second direction is counterclockwise.

[0040] For example, when the first rotation direction is clockwise and the second rotation direction is counterclockwise, and when the first drive assembly 2115 drives the pressure roller 2114 to rotate in the first rotation direction, the pressure roller 2114 can drive the first inner guide roller 2113 and the first outer guide roller 2112 to rotate counterclockwise, thereby driving the round neck and the top to rotate counterclockwise. Furthermore, when the first drive assembly 2115 drives the pressure roller 2114 to rotate in the second rotation direction, it drives the first outer guide roller 2112 to rotate clockwise. Since the first inner guide roller 2113 remains stationary due to the constraint of the one-way bearing 2111, the pressure roller 2114 can drive the top to rotate clockwise, while the round neck remains stationary.

[0041] Please see Figure 1 In some embodiments, the round neck machine 100 includes a first tensioning rotation module 21, the first tensioning rotation module 21 includes a first mounting plate 212, a first round neck limiting groove 213 is formed between a first outer guide roller 2112 and the first mounting plate 212, and the first outer guide roller 2112 is configured to be axially adjustable to adjust the width of the first round neck limiting groove 213.

[0042] Thus, by forming a first round collar limiting groove 213 between the first mounting plate 212 and the first outer guide roller 2112 included in the first tensioning rotation module 21, the round collar can be fitted onto the guide roller 211, and the width of the first round collar limiting groove 213 can be adjusted by adjusting the axial position of the first outer guide roller 2112, so that the first round collar limiting groove 213 can be adapted to round collars of different sizes.

[0043] Specifically, the round neck machine 100 includes a first tensioning rotation module 21, which controls the tension of the round neck and the garment as they are spread on the guide roller 211. The first tensioning rotation module 21 includes a first mounting plate 212, which is fixedly mounted on the platform 10. A first round neck limiting groove 213 is formed between the first mounting plate 212 and the first outer guide roller 2112. The round neck can be fitted into the first round neck limiting groove 213, and the first round neck limiting groove 213 can prevent the round neck from shifting when it rotates. Depending on the size of the round neck, the width of the first round neck limiting groove 213 can be adjusted axially by adjusting the position of the first outer guide roller 2112 on the first inner guide roller 2113, thereby adapting to different round neck sizes and preventing the width of the first round neck limiting groove 213 from being too large or too small, which would affect the sewing effect of the round neck.

[0044] Please see Figure 1 In some embodiments, the round neck machine 100 includes a first tensioning rotation module 21, which includes a first mounting plate 212, a second mounting plate 215, and a second drive assembly 216. The second mounting plate 215 is slidably disposed on the first mounting plate 212, and the pressure roller 2114 is rotatably disposed on the second mounting plate 215. The second drive assembly 216 is used to drive the second mounting plate 215 to slide, thereby causing the pressure roller 2114 to press against or move away from the guide roller 211.

[0045] Thus, by setting the pressure roller 2114 on the second mounting plate 215 included in the first tensioning rotation module 21, and by driving the second mounting plate 215 to slide through the second drive assembly 216 so that the pressure roller 2114 presses against or moves away from the guide roller 211, the second mounting plate 215 that fixes the pressure roller 2114 can be reused, and the pressure roller 2114 can be conveniently controlled to press against or move away from the guide roller 211.

[0046] Specifically, the first tensioning rotation module 21 further includes a first mounting plate 212, a second mounting plate 215, and a second drive assembly 216. The first mounting plate 212 is slidably mounted on a first slide rail 2141, which is mounted on a base 214. The base 214 is mounted on the platform 10 included in the rotary collar machine 100. The base 214 can support components mounted thereon.

[0047] The first mounting plate 212 is also provided with a second drive assembly 216, which can be a drive cylinder or a drive motor, etc., and can be connected to the second mounting plate 215. By setting the second mounting plate 215 on the second slide rail 2142, the second mounting plate 215 can move closer to or away from the guide roller 211 on the second slide rail 2142 under the drive of the second drive assembly 216, thereby driving the pressure roller 2114 set on the end of the second mounting plate 215 near the guide roller 211 to press against or move away from the guide roller 211.

[0048] Optionally, both the first drive assembly 2115 and the pressure roller 2114 are mounted on the second mounting plate 215. The first drive assembly 2115 includes a first drive motor 21151, a synchronous pulley 21152, and a synchronous belt 21153. The synchronous pulley 21152 is connected to the first drive motor 21151, and the pressure roller 2114 is connected to the synchronous pulley 21152 and the first drive motor 21151 via the synchronous belt 21153. Driven by the first drive motor 21151, the synchronous pulley 21152 drives the synchronous belt 21153 to rotate, thereby causing the synchronous belt 21153 to drive the pressure roller 2114 to rotate.

[0049] Please see Figure 1 In some embodiments, the round neck machine 100 includes a second tensioning rotation module 22, which includes a second guide roller 221. The second guide roller 221 includes a second inner guide roller 2212, a second outer guide roller 2211, a third drive assembly 2213, and a fourth drive assembly 2214. The second inner guide roller 2212 is rotatably connected to the platform 10 and is used to fit the round neck. The second outer guide roller 2211 is rotatably connected to the second inner guide roller 2212 and is used to fit the top. The third drive assembly 2213 is used to drive the second outer guide roller 2211 to rotate, and the fourth drive assembly 2214 is used to drive the second inner guide roller 2212 to rotate.

[0050] Thus, by fitting the top and round neck onto the second outer guide roller 2211 and the second inner guide roller 2212 included in the second tensioning rotation module 22, and driving them respectively by the third drive motor 22141 and the fourth drive motor 2171, they can cooperate with the first outer guide roller 2112 and the first inner guide roller 2113 to drive the round neck and top to rotate for sewing.

[0051] Specifically, the round neck machine 100 also includes a second tensioning rotation module 22, which cooperates with the first tensioning rotation module 21 to control the tension of the round neck and the garment. The second tensioning rotation module 22 includes a second guide roller 221, which is used to fit the garment and the round neck. The second guide roller 221 includes a second outer guide roller 2211, a second inner guide roller 2212, a third drive assembly 2213, and a fourth drive assembly 2214. The second inner guide roller 2212 is rotatably connected to the platform 10 and the round neck is fitted onto the second inner guide roller 2212. The second outer guide roller 2211 is rotatably connected to the second inner guide roller 2212 and the top is fitted onto the second outer guide roller 2211. Thus, the top can rotate on the second outer guide roller 2211 under the drive of the third drive component 2213, and the round neck can rotate on the second inner guide roller 2212 under the drive of the fourth drive component 2214. It should be noted that the third drive component 2213 and the fourth drive component 2214 can be the second drive motor 22131 and the third drive motor 22141, respectively.

[0052] A second round neck limiting groove 222 is formed between the second outer guide roller 2211 and the second inner guide roller 2212. The round neck can be fitted into the second round neck limiting groove 222, and the second round neck limiting groove 222 can limit the round neck from shifting when it rotates. Depending on the size of the round neck, the width of the second round neck limiting groove 222 can be adjusted by axially adjusting the position of the second outer guide roller 2211 on the second inner guide roller 2212, thereby adapting to different round neck sizes and preventing the width of the second round neck limiting groove 222 from being too large or too small, which would affect the sewing effect of the round neck.

[0053] Thus, by forming a second round collar limiting groove 222 between the second inner guide roller 2212 and the second outer guide roller 2211 included in the second tensioning rotation module 22, the round collar can be fitted onto the second guide roller 221, and the width of the second round collar limiting groove 222 can be adjusted by adjusting the axial position of the second outer guide roller 2211, so that the second round collar limiting groove 222 can be adapted to round collars of different sizes.

[0054] Please see Figure 1 In some embodiments, the round neck machine 100 includes a first tensioning rotation module 21, which includes a base 214, a first mounting plate 212, and a fifth drive assembly 217. The first mounting plate 212 is slidably disposed on the base 214, and the guide roller 211 is rotatably disposed on the first mounting plate 212. The fifth drive assembly 217 is used to drive the first mounting plate 212 to slide, thereby causing the guide roller 211 to move away from the second guide roller 221 to tension the round neck and the top.

[0055] Thus, by setting the guide roller 211 on the first mounting plate 212, and the first mounting plate 212 being able to slide on the base 214 driven by the fifth drive assembly 217, the distance between the guide roller 211 and the second guide roller 221 can be adjusted to tension the round neck and the top.

[0056] Specifically, the first tensioning rotation module 21 further includes a base 214, a first mounting plate 212, and a fifth drive assembly 217. The base 214 has a first slide rail 2141, the first mounting plate 212 is slidably mounted on the first slide rail 2141, and the guide roller 211 is rotatably mounted on the first mounting plate 212. The fifth drive assembly 217 includes a fourth drive motor 2171, a conveyor wheel 2172, and a conveyor belt 2173. The fourth drive motor 2171 can be connected to the conveyor wheel 2172, and the first mounting plate 212 can be connected to the conveyor wheel 2172 and the fourth drive motor 2171 via the conveyor belt 2173.

[0057] Driven by the fourth drive motor 2171, the first mounting plate 212 can move closer to or away from the second guide roller 221 on the first slide rail 2141, thereby adjusting the distance between the guide roller 211 and the second guide roller 221.

[0058] Please see Figure 1 In some embodiments, the round neck machine 100 includes an operating table 30, which is disposed on the platform 10 and located between the guide roller 211 and the second guide roller 221. The operating table 30 includes an operating surface 31, a first limiting block 33 disposed on the operating surface 31, and a second limiting block 32 slidably disposed on the operating surface 31. The first limiting block 33 and the second limiting block 32 form a third round neck limiting groove 34.

[0059] Thus, by setting a first limiting block 33 and a second limiting block 32 on the table surface of the operating table 30, and forming a third round collar limiting groove 34 between the first limiting block 33 and the second limiting block 32, different sizes of round collars can be adapted by adjusting the distance between the first limiting block 33 and the second limiting block 32, and the round collar can be limited by the third round collar limiting groove 34 to prevent the round collar from shifting during rotation.

[0060] Specifically, the round neck machine 100 also includes an operating table 30, which is set on the platform 10 and located between the guide roller 211 and the second guide roller 221. The round neck and the top are both located on the operating table 30, and the round neck is sewn onto the top on the operating table 30.

[0061] The operating table 30 includes an operating surface 31, a first limiting block 33, and a second limiting block 32. The first limiting block 33 and the second limiting block 32 are both disposed on the operating surface 31, and a third round collar limiting groove 34 is formed between the first limiting block 33 and the second limiting block 32. The round collar can be fitted into the third round collar limiting groove 34, and when the round collar rotates, the third round collar limiting groove 34 can limit the round collar from shifting.

[0062] Depending on the different sizes of the round neck, the width of the third round neck limiting groove 34 can be adjusted by adjusting the distance between the first limiting block 33 and the second limiting block 32, thereby adapting to different round neck sizes and preventing the width of the third round neck limiting groove 34 from being too large or too small, which would affect the sewing effect of the round neck.

[0063] Please see Figure 1 The bone-finding device 40 of this application includes a tensioning rotation module 20 and a bone-finding sensor 421. When the pressure roller 2114 rotates along the first direction, the bone-finding sensor 421 performs bone-finding on the round neck. When the pressure roller 2114 rotates along the second direction, the bone-finding sensor 421 performs bone-finding on the upper garment.

[0064] Thus, when the pressure roller 2114 controls the rotation of the round neck along the first direction, the bone position detector can quickly determine the bone position of the round neck by detecting the round neck. Alternatively, when the pressure roller 2114 controls the rotation of the upper garment along the second direction, the bone position detector can quickly determine the bone position of the upper garment by detecting the upper garment, thereby improving the efficiency of finding the bone positions of the round neck and upper garment.

[0065] Specifically, the round neck machine 100 also includes a bone-finding device 40, which can be used to locate 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.

[0066] The bone-finding device 40 includes a mounting frame 41, a third slide rail 411, a bone position detection component 42, and a double-stroke cylinder 424. The mounting frame 41 is mounted on the platform 10, the third slide rail 411 is mounted on the mounting frame 41, the bone position detection component 42 is slidably mounted on the third slide rail 411 and configured to slide along the guide of the third slide rail 411, and the double-stroke cylinder 424 is mounted on the mounting frame 41 and is used to drive the bone position detection component 42 to move along the guide of the third slide rail 411. It is configured such that when the bone-finding device is used for round necks, the double-stroke cylinder 424 drives the bone position detection component 42 to move for a first stroke, and when the bone-finding device is used for upper garments, the double-stroke cylinder 424 drives the bone position detection component 42 to move for a second stroke.

[0067] The bone position detection component 42 includes a bone-finding sensor 421, two detection rollers 422, and a connecting rod 423. The connecting rod 423 connects the two detection rollers 422 and is coupled to the bone-finding sensor 421. The connecting rod 423 is 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 422 to the bone-finding sensor 421. When the bone-finding sensor 421 detects that there is a height difference between the two detection rollers 422, it determines that the bone position of the round neck or top is in place.

[0068] When the bone position detection component 42 is in the first stroke, the two detection rollers 422 press against the round neck rotating on the first inner guide roller 2113 and the second inner guide roller 2212. When the bone-finding sensor 421 detects a height difference between the two detection rollers 422, it is determined that the bone position of the round neck is in place. When the bone position detection component 42 is in the second stroke, the two detection rollers 422 press against the upper garment rotating on the first outer guide roller 2112 and the second outer guide roller 2211. When the bone-finding sensor 421 detects a height difference between the two detection rollers 422, it is determined that the bone position of the upper garment is in place.

[0069] Optionally, when the bone position detection component 42 is in the first stroke, the first drive component 2115 drives the pressure roller 2114 to rotate, thereby causing the first inner guide roller 2113 to rotate along the second direction and the first outer guide roller 2112 to rotate along the second direction, and the second inner guide roller 2212 and the second outer guide roller 2211 to rotate along the second direction. When the bone position detection component 42 is in the second stroke, the first drive component 2115 drives the pressure roller 2114 to rotate, thereby causing the first outer guide roller 2112 to rotate along the first direction and the second outer guide roller 2211 to rotate along the first direction.
