[0043] See also Figure 1 and Figure 2 A feeding module 100 according to an embodiment of the present invention is used in a sewing machine 1000. The sewing machine 1000 includes a tensioning and rotating module 200 and a sewing module 300. Optionally, the sewing machine 1000 can be used to sew flat hems, overlock hems, overlock round collars, flat hems, upper waistbands, and visible bracing for underwear. In one embodiment, the sewing machine 1000 includes a round collar machine.

[0044] For the convenience of description, the following embodiments are described by taking a round collar knitting machine according to one embodiment of the present invention as an example.

[0045] The tensioning and rotating module 200 is used for tensioning and rotating the round collar and the top 400 put on the round collar, and the sewing module 300 is used for sewing the round collar and the top 400.

[0046] The feeding module 100 includes a first drive assembly 101 and a roller assembly 102. The first drive assembly 101 is connected to the roller assembly 102, which is configured to contact the garment 400. The first drive assembly 101 controls the roller assembly 102 to move the garment 400, thereby conveying the garment 400 to the sewing module 300.

[0047] The first driving assembly 101 is also used to control the roller assembly 102 to adjust the feeding speed of the top 400 when the sewing module 300 sews to different positions of the top 400, so that the feeding speed of the top 400 is compatible with the feeding speed of the sewing module.

[0048] In the above-mentioned feeding module 100, when the sewing module 300 sews to different positions of the top 400, the first driving component 101 can control the roller component 102 to adjust the feeding speed of the top 400, so that the feeding speed of the top 400 is adapted to the feeding speed of the sewing module 300, thereby ensuring the sewing quality and consistency of the sewing effect to a certain extent.

[0049] Specifically, the sewing device 1000 is used to sew a crew neck to the neckline of a jacket 400, and includes a feed module 100, a tensioning and rotating module 200, and a sewing module 300. During operation, the feed module 100, the tensioning and rotating module 200, and the sewing module 300 cooperate to sew the crew neck, which is mounted on the tensioning module, to the jacket 400.

[0050] Optionally, the tensioning and rotating module 200 may include a first roller 201 and a second roller 202, and the crew neck and top 400 may be placed on the first roller 201 and the second roller 1021 at one time. Optionally, the sewing module 300 may include an operating table 301 for supporting the crew neck and top 400 when sewing the crew neck and top 400.

[0051] It should be noted that after the crew neck and the top 400 are put on the tensioning module and before the sewing module 300 starts sewing, the crew neck and the top 400 are in a stretched state.

[0052] The shape of collar is generally arc-shaped, and due to the shape characteristics of arc, the length of outer edge is greater than the length of inner edge. In the arc-shaped collar that is sewn together, the neckline of jacket 400 is at the outer edge of arc, and the round collar is at the inner edge of arc.

[0053] If the neckline of the jacket 400 is stretched to the same degree as the crew neckline during the sewing process, the finished collar may not form a smooth arc, resulting in problems such as tension, distortion, or deformation. Therefore, during the sewing process, the stretching degree of the jacket 400 is typically adjusted according to the shape of the collar to ensure that the finished collar forms a smooth, beautiful arc. The difference between the stretched length of the neckline of the jacket 400 and the stretched length of the crew neckline is called the tolerance.

[0054] For tops 400 and round necks of different fabrics and sizes, the set capacity is different and can be determined based on experimental tests and other methods.

[0055] During the process of sewing the round collar and the top 400, the feeding speed of the top 400 is adjusted so that the feeding speed of the top 400 is adapted to the feeding speed of the sewing module 300, so that the capacity can be evenly distributed, thereby making the sewn collar more round and beautiful.

[0056] In one embodiment, a sewing device 1000 includes a lower feed dog and a roller assembly 102. The lower feed dog may be located in the sewing module 300. The lower feed dog is configured to contact a crew neck collar, while the roller assembly 102 is configured to contact a top garment 400. The lower feed dog can rotate, thereby moving the crew neck collar, thereby conveying it to the sewing module 300. The roller assembly 102 can also rotate, thereby moving the top garment 400, thereby conveying it to the sewing module 300. The crew neck collar and top garment 400 are mounted on the tensioning and rotating module 200. The feed speed of the top garment 400 can be adjusted during the sewing process to match the feed speed of the sewing module 300, thereby improving the uniformity and symmetry of the stitching position and enhancing the sewing effect.

[0057] It should be noted that the feed speed of the sewing module 300 refers to the sewing feed speed of the sewing module 300, while the feed speed of the garment 400 refers to the fabric feed speed provided by the driver to the garment 400. In one embodiment, the feed speed of the sewing module 300 refers to the speed corresponding to the rotational speed of the lower feed dog. The feed speed of the garment 400 refers to the speed corresponding to the rotational speed of the roller assembly 102.

[0058] It is understood that when the feed speed of the jacket 400 is greater than the feed speed of the sewing module 300, that is, the capacity of the jacket 400 is positive, the degree of stretching of the jacket 400 is less than the degree of stretching of the round collar, thereby achieving a capacity sewing effect and forming a smooth arc-shaped collar. Optionally, the feed speed of the jacket 400 can be set higher than the feed speed of the sewing module 300 in the chest area of the garment, so that the front collar fits the neck curve more closely.

[0059] When the feed speed of the jacket 400 is equal to that of the sewing module 300, that is, no additional space is created, the stretch of the jacket 400 is equal to that of the crew neck, thereby achieving simultaneous sewing of the jacket 400 and the crew neck. Optionally, the feed speed of the jacket 400 can be equal to that of the sewing module 300 in the back neck or shoulder area of the garment, so that the back neck can better fit the neck curve or shoulder curve.

[0060] When the feed speed of the garment 400 is slower than that of the sewing module 300, that is, the volume of the garment 400 is negative, the garment 400 is stretched to a greater extent than the crew neck. Alternatively, the feed speed of the garment 400 can be slower than that of the sewing module 300 in the shoulder area of the garment, so that the side collar fits the shoulder curve better.

[0061] In the related art, when sewing collars and tops, it is usually the operator who controls the sewing equipment to sew the collars and tops. However, the sewing effects of different workers cannot be guaranteed to be the same. Even the sewing quality made by the same worker will be affected by the worker's working status.

[0062] In an embodiment of the present invention, a sewing device 1000 includes a feed module 100. The feed module 100 includes a first drive assembly 101 and a roller assembly 102. The first drive assembly 101 is connected to the roller assembly 102, which is configured to contact a garment 400. The first drive assembly 101 is configured to control the roller assembly 102 to move the garment 400, thereby conveying the garment 400 to the sewing module 300. The first drive assembly 101 is further configured to control the roller assembly 102 to adjust the feed speed of the garment 400 as the sewing module 300 sews to different positions on the garment 400, thereby aligning the feed speed of the garment 400 with the feed speed of the sewing module 300.

[0063] Alternatively, the first drive assembly 101 may include but is not limited to a motor, a pneumatic device (e.g., a cylinder). In one embodiment, the first drive assembly 101 includes a first motor 1011, which is connected to a roller 1021 via a gear to control the roller assembly 102 to drive the top 400 to move, so that the top 400 is delivered to the sewing module 300. The first motor 1011 can more accurately control the rotation of the roller assembly 102 through the gear, thereby achieving a more accurate adjustment of the feed speed of the top 400, thereby ensuring that the feed speed of the top 400 matches the feed speed of the sewing module 300 to a certain extent. In one embodiment, the first drive assembly 101 includes a first motor 1011, which is connected to a roller 1021 via a first synchronous belt 1012 to control the roller assembly 102 to drive the top 400 to move, so that the top 400 is delivered to the sewing module 300. The first motor 1011 can provide smoother power transmission through the first synchronous belt 1012 and realize remote transmission, thereby helping to improve the layout flexibility of the sewing device 1000.

[0064] It is understood that the roller assembly 102 can be used to contact the top 400, and the first drive assembly 101 can control the roller 1021 to rotate, so that the top 400 in contact with the surface of the roller 1021 moves under the action of friction and is transported to the sewing module 300. It is understood that the friction force on the surface of the top 400 facing the roller assembly 102 is much greater than the friction force on the surface of the top 400 facing away from the roller assembly 102.

[0065] In some embodiments, please combine Figure 3 The positions of the top 400 include a sewing start position 401 and a first position 402. The first driving assembly 101 is used to control the roller assembly 102 to drive the top 400 to the sewing module 300 during the sewing process of the sewing module 300 from the sewing start position 401 to the first position 402. The feeding speed of the top 400 is less than or equal to the feeding speed of the sewing module 300.

[0066] In the above embodiment, during the sewing process of the sewing module 300 from the sewing starting position 401 to the first position 402, the feeding speed of the top 400 is less than or equal to the feeding speed of the sewing module 300, so that the stretching degree of the top 400 is greater than or equal to the stretching degree of the round collar, which can improve the flatness of the sewn collar between the sewing starting position 401 and the first position 402 and reduce wrinkles and undulations.

[0067] Specifically, in an optional embodiment, the sewing device 1000 includes a first sensor that can be used to detect the seam start position 401 of the crew neck and / or top 400. The crew neck and top 400 are sequentially mounted on the tensioning and rotating module 200. After the first sensor detects the seam start position 401 of the crew neck and / or top 400, the lower feed dog and / or roller assembly 102 can be used to drive the crew neck and / or top 400 to move, so that the seam start position 401 of the crew neck and / or top 400 is located at the sewing module 300, allowing the sewing module 300 to begin sewing at the seam start position 401 of the crew neck and / or top 400. Alternatively, the seam start position 401 of the crew neck and / or top 400 can be manually positioned at the sewing module 300.

[0068] It can be understood that, during the sewing process of the sewing module 300 from the sewing starting position 401 to the first position 402, the feed speed of the top 400 is less than or equal to the feed speed of the sewing module 300, that is, during the sewing process of the sewing module 300 from the sewing starting position 401 to the first position 402, the capacity of the top 400 is a negative value or zero, the stretching degree of the top 400 is greater than or equal to the stretching degree of the round collar, and the first pulling section is between the sewing starting position 401 and the first position 402 of the top 400.

[0069] Optionally, in other embodiments, according to sewing requirements, during the sewing process of the sewing module 300 from the sewing start position 401 to the first position 402, the feeding speed of the top 400 may be greater than the feeding speed of the sewing module 300.

[0070] In one embodiment, the feeding speed of the top 400 at the sewing starting position 401 is V0, the feeding speed of the sewing module 300 is V, and V0 can satisfy 0.9V≤V0≤1.1V.

[0071] In some examples, the feeding speed V0 at the seam starting position 401 of the top 400 is equal to 0.9V, 0.95V, 1.0V, 1.05V, 1.1V, or other values satisfying 0.9V≤V0≤1.1V.

[0072] In one embodiment, the feeding speed of the garment 400 at the first position 402 is V1, the feeding speed of the sewing module 300 is V, and V1 may satisfy 0.8V≤V1≤1.15V.

[0073] In some examples, the feeding speed V1 of the garment 400 at the first position 402 is equal to 0.8V, 0.85V, 0.9V, 0.95V, 1.0V, 1.05V, 1.1V, 1.15V, or other values satisfying 0.8V≤V1≤1.15V.

[0074] In one embodiment, the sewing device 1000 may include a controller that can obtain a preset distance between the seam start position 401 and the first position 402, a preset initial speed V0, and a preset first speed V1. Based on the preset distance between the seam start position 401 and the first position 402, the preset initial speed V0, and the preset first speed V1, the controller can control the first drive assembly 101 to drive the roller assembly 102 to change speed from the preset initial speed V0 to the first speed V1 during the sewing process of the sewing module 300 from the seam start position 401 to the first position 402, so as to drive the top 400 to be fed to the sewing module 300, wherein the feed speed of the top 400 at the seam start position 401 is equal to the initial speed V0, and the feed speed of the top 400 at the first position 402 is equal to the first speed V1, the initial speed V0 is less than, equal to, or greater than the feed speed of the sewing module 300, and the first speed V1 is greater than, less than, or equal to the feed speed of the sewing module 300.

[0075] Optionally, before sewing the garment 400 and the crew neck, the controller may read a pre-stored preset distance between the seam start position 401 and the first position 402, a preset initial speed V0, and a preset first speed V1. Optionally, before sewing the garment 400 and the crew neck, the user may input a preset distance between the seam start position 401 and the first position 402, a preset initial speed V0, and a preset first speed V1. Optionally, before sewing the garment 400 and the crew neck, the controller may retrieve the preset distance between the seam start position 401 and the first position 402, a preset initial speed V0, and a preset first speed V1 based on user input of information such as fabric material and size. Optionally, the sewing device 1000 may include an image sensor, and the controller may be electrically connected to the image sensor. The image sensor may be used to identify information such as fabric material and size. Optionally, the user may input information through a human-computer interaction module of the sewing device 1000. The human-computer interaction module may include, but is not limited to, an input panel or a terminal device capable of communicating with the sewing device 1000. Optionally, the terminal device may include but is not limited to a mobile phone, a tablet computer, a personal computer, a server, a wearable smart device (such as a smart helmet, smart glasses, a smart bracelet, a smart watch), etc.

[0076] In some embodiments, please combine Figure 3The position of the top 400 includes a second position 403 behind the first position 402 in the movement direction of the top 400. The first driving assembly 101 is used to control the roller assembly 102 to accelerate and drive the top 400 to the sewing module 300 during the sewing process of the sewing module 300 from the first position 402 to the second position 403. The feeding speed of the top 400 at the second position 403 is greater than the feeding speed of the sewing module 300.

[0077] In the above embodiment, during the sewing process of the sewing module 300 from the first position 402 to the second position 403, the feeding speed of the top 400 gradually increases to be greater than the feeding speed of the sewing module 300, so that the stretching degree of the top 400 gradually decreases to be less than the stretching degree of the round collar, and a tolerant sewing effect can be achieved, so that to a certain extent, the sewn collar can form a more rounded and beautiful arc shape between the first position 402 and the second position 403.

[0078] Specifically, the feeding speed of the top 400 at the second position 403 is greater than the feeding speed of the sewing module 300 , that is, when the sewing module 300 is sewn to the second position 403 , the feeding speed of the top 400 is greater than the feeding speed of the sewing module 300 .

[0079] During the sewing process of the sewing module 300 from the first position 402 to the second position 403, the roller assembly 102 is controlled to accelerate and drive the top 400 to the sewing module 300, that is, during the sewing process of the sewing module 300 from the first position 402 to the second position 403, the rotation speed of the roller assembly 102 is increased to increase the feeding speed of the top 400, and drive the top 400 to the sewing module 300.

[0080] It can be understood that during the sewing process of the sewing module 300 from the sewing start position 401 to the first position 402, the feeding speed of the top 400 is less than or equal to the feeding speed of the sewing module 300, that is, the feeding speed of the top 400 at the first position 402 is less than or equal to the feeding speed of the sewing module 300.

[0081] During the sewing process of the sewing module 300 from the first position 402 to the second position 403, the feeding speed of the top 400 gradually increases. When sewing to the second position 403, the feeding speed of the top 400 is greater than the feeding speed of the sewing module 300.

[0082] During the sewing process of sewing module 300 from first position 402 to second position 403, the capacity of top 400 gradually increases from a negative value or zero to a positive value, and the stretch of top 400 gradually decreases until it is less than the stretch of the crew neck, thereby achieving a capacity sewing effect. The area between first position 402 and second position 403 of top 400 is an acceleration capacity section.

[0083] Optionally, in other embodiments, according to sewing requirements, during the sewing process of the sewing module 300 from the first position 402 to the second position 403, the feed speed of the top 400 gradually increases, and when sewing to the second position 403, the feed speed of the top 400 is equal to the feed speed of the sewing module 300.

[0084] In one embodiment, the sewing device 1000 may include a controller that can obtain a preset distance between the first position 402 and the second position 403, and a preset second speed V2. Based on the preset distance between the first position 402 and the second position 403, and the preset second speed V2, the controller can control the first drive assembly 101 to drive the roller assembly 102 to uniformly accelerate from the preset first speed V1 to the preset second speed V2 during the sewing process of the sewing module 300 from the first position 402 to the second position 403, thereby driving the top 400 to be fed to the sewing module 300, with the feed speed of the top 400 at the second position 403 being equal to the second speed V2, and the second speed V2 being greater than or equal to the feed speed of the sewing module 300.

[0085] In one embodiment, the sewing module 300 may include a needle. The needle refers to the needle of the sewing module 300, which is used to penetrate the fabric to sew the top 400 and the crew neck. During the sewing process, the needle moves up and down and cooperates with the feeding module 100 to form a lock or chain stitch. The controller can obtain the corresponding set needle step number based on the distance between the preset seam start position 401 and the first position 402, so that when the needle step number reaches the set needle step number, that is, when the sewing module 300 starts to sew the top 400 and the crew neck from the first position 402 to the second position 403, the first drive assembly 101 is controlled to drive the roller assembly 102 to accelerate the movement of the top 400 and send it to the sewing module 300. Among them, the needle step number is used to measure the sewing progress.

[0086] In one embodiment, the feeding speed of the garment 400 at the second position 403 is V2, the feeding speed of the sewing module 300 is V, and V2 may satisfy 1V≤V2≤1.4V.

[0087] In some examples, the feeding speed V2 of the garment 400 at the second position 403 is equal to 1V, 1.05V, 1.1V, 1.15V, 1.2V, 1.25V, 1.3V, 1.35V, 1.4V, or other values satisfying 1V≤V2≤1.4V.

[0088] In some embodiments, please combine Figure 3 , the position of the top 400 includes at least one third position 404 located between the first position 402 and the second position 403;

[0089] The feed speed of the top 400 meets the following conditions:

[0090] The feed speed at the third position 404 adjacent to the first position 402 is greater than the feed speed at the first position 402;

[0091] In two adjacent third positions 404 , the feeding speed of the third position 404 located later in the moving direction of the garment 400 is greater than the feeding speed of the third position 404 located earlier.

[0092] In the above embodiment, at least one third position 404 may be provided between the first position 402 and the second position 403, so that the degree of acceleration between different positions can be more accurately controlled, thereby more accurately controlling the capacity distribution, improving the capacity sewing effect, and further enhancing the roundness and beauty of the collar.

[0093] Specifically, in one embodiment, during the sewing process from the first position 402 to the third position 404 adjacent to the first position 402, the control roller assembly 102 is accelerated to drive the top 400 to the sewing module 300, and the feeding speed of the top 400 at the third position 404 adjacent to the first position 402 is greater than the feeding speed at the first position 402.

[0094] In one embodiment, during the sewing process of two adjacent third positions 404, the control roller assembly 102 accelerates and drives the top 400 to the sewing module 300, and along the movement direction of the top 400, the feeding speed of the rear third position 404 is greater than the feeding speed of the front third position 404.

[0095] Optionally, in one embodiment, during the sewing process from the third position 404 adjacent to the second position 403 to the second position 403, the control roller assembly 102 is accelerated to drive the top 400 to the sewing module 300, and the feeding speed of the top 400 at the second position 403 is greater than, equal to or less than the feeding speed of the third position 404 adjacent to the second position 403.

[0096] In one embodiment, the sewing device 1000 may include a controller that can obtain a preset distance between a first position 402 and a third position 404 adjacent to the first position 402, a preset distance between two adjacent third positions 404, a preset distance between a third position 404 adjacent to the second position 403 and the second position 403, as well as a preset third speed, a preset fourth speed, and a preset second speed V2. The feed speed of the garment 400 at the third position 404 adjacent to the first position 402 is equal to the third speed, the feed speed of the garment 400 at the third position 404 adjacent to the second position 403 is equal to the fourth speed, and the feed speed of the garment 400 at the second position 403 is equal to the second speed V2, which is greater than or equal to the feed speed of the sewing module 300. The third speed is greater than the first speed V1, the fourth speed is greater than the third speed, and the second speed V2 is greater than, equal to, or less than the fourth speed.

[0097] In one embodiment, when there is only one third position 404 between the first position 402 and the second position 403, during the sewing process of the sewing module 300 from the first position 402 to the second position 403, between the first position 402 and the third position 404, the roller assembly 102 is controlled to uniformly accelerate from a preset first speed V1 to a preset third speed V3. Between the third position 404 and the second position 403, the roller assembly 102 is controlled to change speed from the preset third speed V3 to the preset second speed V2. The feed speed of the garment 400 at the third position 404 is equal to the third speed V3, and the third speed V3 is greater than the feed speed of the sewing module 300. It is understood that the third position 404 can be located at any position between the first position 402 and the second position 403.

[0098] Optionally, when there is only one third position 404 between the first position 402 and the second position 403, the feeding speed of the top 400 at the third position 404 is V3, the feeding speed of the sewing module 300 is V, and V3 can satisfy 1V<V3≤1.25V.

[0099] In some examples, the feeding speed V3 of the garment 400 at the third position 404 is equal to 1.02V, 1.04V, 1.06V, 1.08V, 1.1V, 1.12V, 1.14V, 1.16V, 1.18V, 1.2V, 1.25V or satisfies 1V<V3≤1.25V.

[0100] In one embodiment, when there are multiple third positions 404 between the first position 402 and the second position 403, during the sewing process of the sewing module 300 from the first position 402 to the second position 403, between the first position 402 and the third position 404 adjacent to the first position 402, the roller assembly 102 is controlled to uniformly accelerate from the preset first speed V1 to the preset third speed, between two adjacent third positions 404, the roller assembly 102 is controlled to uniformly accelerate to the preset speed, and between the third position 404 adjacent to the second position 403 and the second position 403, the roller assembly 102 is controlled to change speed from the preset fourth speed to the preset second speed V2. It is understood that the multiple third positions 404 can be located at any position between the first position 402 and the second position 403.

[0101] In some embodiments, please combine Figure 3 The position of the top 400 includes a fourth position 405 behind the second position 403 in the movement direction of the top 400. The first driving assembly 101 is used to control the roller assembly 102 to slow down and drive the top 400 to the sewing module 300 during the sewing process of the sewing module 300 from the second position 403 to the fourth position 405. The feeding speed of the top 400 at the fourth position 405 is less than or equal to the feeding speed of the sewing module 300.

[0102] In the above embodiment, during the sewing process of the sewing module 300 from the second position 403 to the fourth position 405, the feed speed of the top 400 gradually decreases to less than or equal to the feed speed of the sewing module 300, so that the stretching degree of the top 400 gradually increases to greater than or equal to the stretching degree of the round collar, and a symmetrical capacity sewing effect with the acceleration capacity section can be achieved, so that the sewn collar can form a more rounded and beautiful arc shape between the first position 402 and the second position 403 to a certain extent.

[0103] Specifically, the feeding speed of the top 400 at the fourth position 405 is less than or equal to the feeding speed of the sewing module 300 , that is, when the sewing module 300 is sewn to the fourth position 405 , the feeding speed of the top 400 is less than or equal to the feeding speed of the sewing module 300 .

[0104] During the sewing process of the sewing module 300 from the second position 403 to the fourth position 405, the roller assembly 102 is controlled to slow down and drive the top 400 to the sewing module 300. That is, during the sewing process of the sewing module 300 from the second position 403 to the fourth position 405, the rotation speed of the roller assembly 102 is reduced to reduce the feeding speed of the top 400 and drive the top 400 to the sewing module 300.

[0105] It can be understood that the feeding speed of the top 400 in the second position 403 is greater than the feeding speed of the sewing module 300.

[0106] During the sewing process of the sewing module 300 from the second position 403 to the fourth position 405, the feed speed of the top 400 gradually decreases from greater than the feed speed of the sewing module 300 to less than or equal to the feed speed of the sewing module 300. When sewing to the fourth position 405, the feed speed of the top 400 is less than or equal to the feed speed of the sewing module 300.

[0107] During the sewing process of the sewing module 300 from the second position 403 to the fourth position 405, the capacity of the top 400 gradually decreases from a positive value, and the stretch of the top 400 gradually increases until it is greater than or equal to the stretch of the crew neck, thereby achieving an accommodative sewing effect. The area between the second position 403 and the fourth position 405 of the top 400 is a deceleration and accommodative section. It can be understood that during the deceleration and accommodative section, the feed speed of the top 400 is greater than or equal to the feed speed of the sewing module 300, thus achieving an accommodative sewing effect.

[0108] Alternatively, in other embodiments, the feed speed of the garment 400 at the fourth position 405 may be greater than the feed speed of the sewing module 300, depending on sewing requirements. In one embodiment, the sewing device 1000 may include a controller that can obtain a preset distance between the second position 403 and the fourth position 405, as well as a preset fifth speed V4. Based on the preset distance between the second position 403 and the fourth position 405, and the preset fifth speed V4, the controller can control the first drive assembly 101 to drive the roller assembly 102 to uniformly decelerate from the preset second speed V2 to the preset fifth speed V4 during the sewing process of the sewing module 300 from the second position 403 to the fourth position 405, thereby driving the garment 400 to be fed to the sewing module 300. The feed speed of the garment 400 at the fourth position 405 is equal to the fifth speed V4, and the fifth speed V4 is greater than, less than, or equal to the feed speed of the sewing module 300.

[0109] In one embodiment, the feeding speed of the garment 400 at the fourth position 405 is V4, the feeding speed of the sewing module 300 is V, and V4 may satisfy 0.8V≤V4≤1.15V.

[0110] In some examples, the feeding speed V4 of the garment 400 at the fourth position 405 is equal to 0.8V, 0.85V, 0.9V, 1.0V, 1.1V, 1.15V, or other values satisfying 0.8V≤V4≤1.15V.

[0111] In some embodiments, please combine Figure 3, the positions of the top 400 include at least one fifth position 406 located between the second position 403 and the fourth position 405;

[0112] The feed speed of the top 400 meets the following conditions:

[0113] The feed speed at the fifth position 406 adjacent to the second position 403 is lower than the feed speed at the second position 403;

[0114] In two adjacent fifth positions 406 , the feeding speed of the fifth position 406 at the rear in the movement direction of the garment 400 is lower than the feeding speed of the fifth position 406 at the front;

[0115] The feed speed at the fourth position 405 is lower than the feed speed at the fifth position 406 adjacent to the fourth position 405 .

[0116] In the above embodiment, at least one fifth position 406 may be provided between the second position 403 and the fourth position 405, so that the degree of deceleration between different positions can be more accurately controlled, thereby more accurately controlling the capacity distribution, improving the capacity sewing effect, and further enhancing the roundness and beauty of the collar.

[0117] Specifically, in one embodiment, during the sewing process from the second position 403 to the fifth position 406 adjacent to the second position 403, the control roller assembly 102 slows down and drives the top 400 to the sewing module 300, and the feeding speed of the top 400 at the fifth position 406 adjacent to the second position 403 is less than the feeding speed at the second position 403.

[0118] In one embodiment, during the sewing process of two adjacent fifth positions 406, the control roller assembly 102 is decelerated to drive the top 400 to the sewing module 300. Along the movement direction of the top 400, the feeding speed of the rear fifth position 406 is less than the feeding speed of the front fifth position 406.

[0119] In one embodiment, during the sewing process from the fifth position 406 adjacent to the fourth position 405 to the fourth position 405, the control roller assembly 102 is decelerated to drive the top 400 to the sewing module 300, and the feeding speed of the top 400 at the fourth position 405 is less than the feeding speed of the fifth position 406 adjacent to the fourth position 405.

[0120] In one embodiment, the sewing device 1000 may include a controller that can obtain a preset distance between the second position 403 and a fifth position 406 adjacent to the second position 403, a preset distance between two adjacent fifth positions 406, a preset distance between the fifth position 406 adjacent to the fourth position 405 and the fourth position 405, as well as a preset sixth speed, a preset seventh speed, and a preset fifth speed V4. The feed speed of the garment 400 at the fifth position 406 adjacent to the second position 403 is equal to the sixth speed, the feed speed of the garment 400 at the fifth position 406 adjacent to the fourth position 405 is equal to the seventh speed, and the feed speed of the garment 400 at the fourth position 405 is equal to the fifth speed V4, which is less than, equal to, or greater than the feed speed of the sewing module 300. The sixth speed is less than the second speed V2, the seventh speed is less than the sixth speed, and the fifth speed V4 is less than the seventh speed.

[0121] In one embodiment, when there is only one fifth position 406 between the second position 403 and the fourth position 405, during the sewing process of the sewing module 300 from the first position to the fourth position 405, between the second position 403 and the fourth position 405, the control roller assembly 102 is uniformly decelerated from the preset second speed V2 to the preset sixth speed V5, and between the fifth position 406 and the fourth position 405, the control roller assembly 102 is uniformly decelerated from the preset sixth speed V5 to the preset fifth speed V4. It is understood that the fifth position 406 can be located at any position between the second position 403 and the fourth position 405.

[0122] Optionally, when there is only one fifth position 406 between the second position 403 and the fourth position 405, the feeding speed of the top 400 at the fifth position 406 is V5, and the feeding speed of the sewing module 300 is V, V5 can satisfy 1V≤V5≤1.25V, and is greater than the feeding speed V4 of the top 400 at the fourth position 405.

[0123] In some examples, the feeding speed V5 of the top 400 at the third position 404 is equal to 1V, 1.02V, 1.04V, 1.06V, 1.08V, 1.1V, 1.12V, 1.14V, 1.16V, 1.18V, 1.2V, 1.25V or other values that satisfy 1V≤V5≤1.25V and V5>V4.

[0124] In one embodiment, when there are multiple fifth positions 406 between the second position 403 and the fourth position 405, during the sewing process of the sewing module 300 from the second position 403 to the fourth position 405, between the second position 403 and the fifth position 406 adjacent to the second position 403, the roller assembly 102 is controlled to uniformly decelerate from the preset second speed V2 to the preset sixth speed, between two adjacent fifth positions 406, the roller assembly 102 is controlled to uniformly decelerate to the preset speed, and between the fifth position 406 adjacent to the fourth position 405 and the fourth position 405, the roller assembly 102 is controlled to uniformly decelerate from the preset seventh speed to the preset fifth speed V4. It is understood that the multiple fifth positions 406 can be located at any position between the second position 403 and the fourth position 405.

[0125] In some embodiments, please combine Figure 3 The position of the top 400 includes a sixth position 407 behind the fourth position 405 in the movement direction of the top 400. The first driving assembly 101 is used to control the roller assembly 102 to drive the top 400 to the sewing module 300 during the sewing process of the sewing module 300 from the fourth position 405 to the sixth position 407. The feeding speed of the top 400 is less than or equal to the feeding speed of the sewing module 300.

[0126] In the above embodiment, during the sewing process of the sewing module 300 from the fourth position 405 to the sixth position 407, the feeding speed of the top 400 is less than or equal to the feeding speed of the sewing module 300, so that the stretching degree of the top 400 is greater than or equal to the stretching degree of the round collar, which can improve the flatness of the sewn collar between the fourth position 405 and the sixth position 407, reduce wrinkles and undulations, and at the same time form a sewing effect symmetrical to the first pulling section.

[0127] Specifically, during the sewing process of the sewing module 300 from the fourth position 405 to the sixth position 407, the feeding speed of the top 400 is less than or equal to the feeding speed of the sewing module 300, that is, during the sewing process of the sewing module 300 from the fourth position 405 to the sixth position 407, the fabric of the top 400 delivered to the sewing module 300 is less than or equal to the round neck fabric, that is, the capacity of the top 400 is a negative value or zero, the stretching degree of the top 400 is greater than or equal to the stretching degree of the round neck, and the second pulling section is between the fourth position 405 and the sixth position 407 of the top 400.

[0128] Optionally, according to sewing requirements, during the sewing process of the sewing module 300 from the fourth position 405 to the sixth position 407, the feeding speed of the top 400 is greater than the feeding speed of the sewing module 300.

[0129] In one embodiment, the sewing device 1000 may include a controller that can obtain a preset distance between the fourth position 405 and the sixth position 407, and a preset eighth speed V6. Based on the preset distance between the fourth position 405 and the sixth position 407, and the preset eighth speed V6, the controller can control the first drive assembly 101 to drive the roller assembly 102 to change from the preset fifth speed V4 to the eighth speed V6 during the sewing process of the sewing module 300 from the fourth position 405 to the sixth position 407, thereby driving the upper garment 400 to be fed to the sewing module 300. The feeding speed of the upper garment 400 at the sixth position 407 is equal to the eighth speed V6, and the eighth speed V6 is greater than, less than, or equal to the feeding speed of the sewing module 300.

[0130] In one embodiment, during the sewing process of the sewing module 300 from the fourth position 405 to the sixth position 407, the feeding speed of the top 400 is V6, the feeding speed of the sewing module 300 is V, and V6 can satisfy 0.8V≤V6≤1.1V.

[0131] In some examples, the feeding speed V6 of the garment 400 at the sixth position 407 is equal to 0.8V, 0.85V, 0.9V, 0.95V, 1.0V, 1.1V, or other values satisfying 0.8V≤V6≤1.1V.

[0132] In some embodiments, please combine Figure 3 The first driving component 101 is used to control the roller component 102 to accelerate during the sewing process of the sewing module 300 from the sixth position 407 to the sewing start position 401 so that the feeding speed of the top 400 is greater than or equal to the feeding speed of the sewing module 300 and drives the top 400 to be sent to the sewing module 300.

[0133] In the above embodiment, during the sewing process of the sewing module 300 from the sixth position 407 to the seam starting position 401, the feed speed of the top 400 is gradually increased to be greater than or equal to the feed speed of the sewing module 300, so that the stretching degree of the top 400 is gradually reduced, and it can be transitioned to synchronous sewing, thereby improving the neatness and beauty of the sewing stitches while improving the flatness of the sewn collar between the sixth position 407 and the seam starting position 401, forming a relatively gentle arc shape.

[0134] Specifically, during the sewing process of the sewing module 300 from the sixth position 407 to the seam starting position 401, the roller assembly 102 is controlled to accelerate the top 400 so that the feeding speed of the top 400 is greater than or equal to the feeding speed of the sewing module 300, and the top 400 is driven to be sent to the sewing module 300. That is, during the sewing process of the sewing module 300 from the sixth position 407 to the seam starting position 401, the rotation speed of the roller assembly 102 is increased to increase the feeding speed of the top 400 until it is greater than or equal to the feeding speed of the sewing module 300, and the top 400 is driven to be sent to the sewing module 300.

[0135] During the sewing process of the sewing module 300 from the sixth position 407 to the seam start position 401, the stretch of the top 400 gradually decreases, thereby achieving a synchronized sewing effect. The top 400 may include a transition section and a uniform speed section between the fourth position 405 and the sixth position 407. During the transition section, the feed speed of the top 400 gradually increases to a speed greater than or equal to the feed speed of the sewing module 300, while the stretch of the top 400 gradually decreases to a speed less than or equal to the stretch of the crew neck. During the uniform speed section, the feed speed of the top 400 remains unchanged, and the stretch of the top 400 remains unchanged.

[0136] In some embodiments, please combine Figure 3 The position of the top 400 includes a seventh position 408 between the sixth position 407 and the seam start position 401. The first drive assembly 101 is used to control the roller assembly 102 to accelerate and drive the top 400 to the sewing module 300 during the sewing process of the sewing module 300 from the sixth position 407 to the seventh position 408. The feeding speed of the top 400 in the seventh position 408 is greater than or equal to the feeding speed of the sewing module 300. The first drive assembly 101 is also used to control the roller assembly 102 to drive the top 400 to the sewing module 300 during the sewing process of the sewing module 300 from the seventh position 408 to the seam start position 401. The feeding speed of the top 400 is greater than or equal to the feeding speed of the sewing module 300.

[0137] In the above embodiment, a seventh position 408 may be provided between the sixth position 407 and the sewing start position 401, so that the proportion of the transition section and the uniform speed section can be more accurately controlled, thereby improving the sewing effect.

[0138] Specifically, in one embodiment, during the sewing process from the sixth position 407 to the seventh position 408, the control roller assembly 102 is controlled to accelerate and drive the garment 400 to the sewing module 300. The feeding speed of the garment 400 at the seventh position 408 is greater than or equal to the feeding speed of the sewing module 300. The garment 400 is in a transition section between the sixth position 407 and the seventh position 408.

[0139] In one embodiment, during the sewing process from the seventh position 408 to the seam start position 401, the control roller assembly 102 drives the garment 400 to the sewing module 300 at a constant speed. The garment 400 is in a constant speed section between the seventh position 408 and the seam start position 401.

[0140] In one embodiment, the sewing device 1000 may include a controller that can obtain a preset distance between the sixth position 407 and the seventh position 408, and a preset ninth speed V7. Based on the preset distance between the sixth position 407 and the seventh position 408, and the preset ninth speed V7, the controller can control the first drive assembly 101 to drive the roller assembly 102 to uniformly accelerate from the preset eighth speed V6 to the ninth speed V7 during the sewing process of the sewing module 300 from the sixth position 407 to the seventh position 408, thereby driving the top 400 to be fed to the sewing module 300, and the feeding speed of the top 400 at the seventh position 408 is equal to the ninth speed V7.

[0141] Optionally, in one embodiment, during the sewing process from the seventh position 408 to the sewing start position 401, the control roller assembly 102 drives the top 400 to the sewing module 300 at a uniform speed of the ninth speed V7.

[0142] In one embodiment, the feeding speed of the garment 400 at the seventh position 408 is V7, the feeding speed of the sewing module 300 is V, and V7 may satisfy 1V≤V7≤1.15V.

[0143] In some examples, the feeding speed V7 of the garment 400 at the seventh position 408 is equal to 1V, 1.02V, 1.04V, 1.06V, 1.08V, 1.1V, 1.12V, 1.14V, 1.15V, or satisfies 1V≤V7≤1.15V.

[0144] It can be understood that the seventh position 408 can be located at any position between the sixth position 407 and the seam starting position 401 .

[0145] In one embodiment, the seventh position 408 may be located proximate to the sixth position 407 .

[0146] In one example, the feed speed of the sewing module 300 is V, V0 equals 0.9V, V1 equals 0.9V, V3 equals 1.25V, V2 equals 1.25V, V5 equals 1.2V, V4 equals 0.9V, V6 equals 1V, and V7 equals 1.05V.

[0147] In one example, the feed speed of the sewing module 300 is V, V0 equals 1.1V, V1 equals 1.15V, V3 equals 1.3V, V2 equals 1.3V, V5 equals 1.25V, V4 equals 1.15V, V6 equals 1.1V, and V7 equals 1.15V.

[0148] In one example, the feed speed of the sewing module 300 is V, V0 equals 0.9V, V1 equals 0.85V, V3 equals 1.05V, V2 equals 1V, V5 equals 1V, V4 equals 0.85V, V6 equals 0.9V, and V7 equals 1.05V.

[0149] In one example, the feeding speed of the sewing module 300 is V, V0 is equal to 1V, V1 is equal to 0.9V, V3 is equal to 1.1V, V2 is equal to 1.2V, V5 is equal to 1.1V, V4 is equal to 0.9V, V6 is equal to 1V, and V7 is equal to 1V.

[0150] In some embodiments, please combine Figure 1 The first driving assembly 101 includes a first motor 1011 and a first synchronous belt 1012 , the roller assembly 102 includes a roller 1021 , and the first motor 1011 is connected to the roller 1021 through the first synchronous belt 1012 .

[0151] In the above embodiment, the first motor 1011 can provide smoother power transmission through the first synchronous belt 1012 and can realize remote transmission, thereby facilitating improvement of the layout flexibility of the sewing device 1000 .

[0152] Specifically, the first motor 1011 may include a first output shaft, and the first drive assembly 101 may include a synchronous wheel 1013, which is fixedly connected to the synchronous wheel 1013 and the roller 1021. The first synchronous belt 1012 may be mounted on the first output shaft and the synchronous wheel 1013. When the first motor 1011 is running, the first output shaft of the first motor 1011 rotates and drives the synchronous wheel 1013 to rotate via the first synchronous belt 1012, and the roller 1021 fixedly connected to the synchronous wheel 1013 can rotate in the same direction.

[0153] The roller 1021 is in contact with the top 400 , and the rotating roller 1021 can drive the top 400 to the sewing module 300 under the action of friction.

[0154] In some embodiments, please combine Figure 1The roller assembly 102 includes two rollers 1021 and two first motors 1011. The two first motors 1011 are respectively connected to the two rollers 1021. The feeding module 100 includes a second driving assembly 103. The second driving assembly 103 is connected to the roller assembly 102 and is used to control the two rollers 1021 to alternately contact the top 400 to transport the top 400 to the sewing module 300.

[0155] In the above embodiment, the second driving assembly 103 can control the two rollers 1021 to contact the top 400 alternately, thereby ensuring the stability of the top 400 being delivered to the sewing module 300 during the sewing process to a certain extent.

[0156] Specifically, the second driving assembly 103 can be used to control the two rollers 1021 to contact the top 400 alternately, that is, during the sewing process, control any one of the two rollers 1021 to contact the top 400.

[0157] The two first motors 1011 respectively control the two rollers 1021. When the two first motors 1011 are running, they respectively control the two rollers 1021 to rotate synchronously at the speed of the corresponding first motor 1011. The rollers 1021 that rotate and contact the top 400 are used to drive the top 400 to move and send it to the sewing module 300 for sewing with the round collar.

[0158] In some embodiments, please combine Figure 4 The second driving assembly 103 is also used to adjust the position of the top 400 relative to the round collar when the roller 1021 contacts the top 400 so that the edge of the top 400 is basically aligned with the edge of the round collar.

[0159] In the above embodiment, the second driving assembly 103 can adjust the position of the top 400 relative to the round collar so that the edge of the top 400 is substantially aligned with the edge of the round collar, thereby improving the sewing effect.

[0160] Specifically, the second drive assembly 103 can control the two rollers 1021 to move linearly in a first direction. When the rollers 1021 contact the top 400, the rollers 1021 can be controlled to move linearly in a second direction, thereby driving the top 400 to move in the second direction. The first and second directions are perpendicular to each other and are perpendicular to the edge of the top 400.

[0161] Optionally, the sewing device 1000 may include a second sensor, which can be used to detect the position of the edge of the top 400. When the position of the edge of the top 400 is not within the preset position 600, the second drive component 103 can be used to control the roller 1021 in contact with the top 400 to move linearly in the second direction, thereby driving the top 400 to move in the second direction, so that the edge of the top 400 is located within the preset position 600 to be basically aligned with the edge of the round collar, thereby improving the sewing effect.

[0162] It should be noted that the first drive component 101 and the second drive component 103 can synchronously control the roller component 102 to send the top 400 to the sewing module 300 to achieve capacity control, while adjusting the position of the top 400 relative to the round collar so that the edge of the top 400 is basically aligned with the edge of the round collar to improve the sewing effect.

[0163] It can be understood that the roller assembly 102 can be used to contact the top 400 to achieve capacity control, and can also be used to contact the top 400 to adjust the edge of the top 400, thereby eliminating the need for additional correction devices and helping to improve the space utilization of the sewing equipment 1000.

[0164] In some embodiments, please combine Figure 1 The second driving assembly 103 includes a second motor 1031, a second synchronous belt (not shown) and a cam 1033. The second motor 1031 is connected to the cam 1033 through the second synchronous belt, and the two rollers 1021 are movably connected to the cam 1033.

[0165] In the above embodiment, the second motor 1031 can drive the roller 1021 to move and contact the top 400 and adjust the position of the edge of the top 400 through the second synchronous belt and cam 1033, so as to simultaneously realize capacity control and correction and improve the sewing effect.

[0166] Specifically, the two rollers 1021 can be movably connected to the cam 1033 through a cam 1033 follower.

[0167] In one embodiment, two eccentric holes are provided on both end surfaces of the cam 1033 along the edge of the garment 400. The two eccentric holes are symmetrical about the center of the eccentric axis. Two cam followers 1033 can be mounted on the two eccentric holes, respectively, and the two cam followers 1033 are respectively connected to the roller 1021. The second motor 1031 can include a second output shaft, and a second synchronous belt can be mounted on the second output shaft and the cam 1033. When the second motor 1031 is running, the second output shaft of the second motor 1031 rotates and drives the cam 1033 to rotate via the second synchronous belt. The cam followers 1033 mounted in the eccentric holes can drive the roller 1021 to move in the first direction and the second direction.

[0168] In one embodiment, one roller 1021 moves in a first direction toward the top 400 to contact the top 400 and moves in a second direction to adjust the edge of the top 400 , and the other roller 1021 moves in the first direction away from the top 400 .

[0169] The second motor 1031 can provide smoother power transmission through the second synchronous belt and realize remote transmission, which is beneficial to improving the layout flexibility of the sewing device 1000.
