[0061] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0062] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0063] This invention discloses a method for controlling the laying speed of garment sewing lining, as shown in the attached figure. Figure 1 As shown, it includes:

[0064] Get the current sewing speed;

[0065] The current sewing speed mentioned in the text refers to the current sewing speed of the top thread. The current sewing speed can be obtained by detecting the stitches of the top thread or by directly detecting the sewing needle.

[0066] The current sewing mode is determined based on the current sewing speed;

[0067] Different sewing speeds correspond to different sewing modes, and the relationship between sewing speed and sewing mode can be pre-stored in memory. Sewing modes include normal sewing mode, acceleration / deceleration sewing mode, and turning sewing mode. In normal sewing mode, both the value and direction of the sewing speed remain constant. In acceleration / deceleration sewing mode, the value of the sewing speed changes, but the direction remains constant. In turning sewing mode, both the value and direction of the sewing speed change.

[0068] Based on the current sewing mode and the current sewing speed, the current laying speed corresponding to the current sewing speed is obtained; that is, different sewing modes correspond to different preset correspondences. Under different sewing modes, the corresponding laying speed is determined according to the corresponding preset correspondence and sewing speed.

[0069] This invention can automatically adjust the laying speed of garment lining according to the sewing speed of the top thread in various sewing modes, ensuring that the sewing speed and laying speed are always matched, avoiding the garment lining being mistakenly sewn into the stitches, and effectively improving sewing quality.

[0070] When the current sewing mode is normal sewing mode, the correspondence between sewing speed and laying speed is as follows:

[0071]

[0072] in, The laying speed is in normal sewing mode, in m / s; 'a' is a setting coefficient. The sewing speed is in normal sewing mode, measured in m / s. Normal sewing mode in this text refers to uniform speed sewing.

[0073] In normal sewing mode, the sewing speed and the laying speed maintain a constant ratio. The laying speed can be directly calculated based on the measured sewing speed, so that the sewing speed of the top thread matches the laying speed of the garment sewing lining.

[0074] When the current sewing mode is acceleration / deceleration sewing mode, the correspondence between sewing speed and laying speed is as follows:

[0075]

[0076] in, The laying speed in acceleration / deceleration sewing mode is expressed in m / s; 'a' is the setting coefficient. The initial sewing speed in acceleration / deceleration sewing modes, expressed in m / s; The final speed in acceleration / deceleration sewing mode is expressed in m / s; z is the empirical correction index. and This can be obtained in real time using a speed sensor. This correspondence represents the equivalent real-time speed under acceleration / deceleration sewing modes, which can be understood as controlling and correcting the laying speed in acceleration / deceleration sewing modes. This makes it a directly controllable real-time equivalent speed under normal sewing mode, and it can be directly controlled by the set coefficient 'a'.

[0077] It is important to note that and The order of the two cannot be changed. This improvement aims to directly construct a method that can be controlled by a set coefficient 'a' using the correction index, and only the formula needs to be adjusted.

[0078] In acceleration / deceleration sewing modes, the results are obtained through detection. and Then use the formula Calculate the laying speed in acceleration / deceleration sewing modes to ensure that the sewing speed of the underline in acceleration / deceleration sewing modes matches the laying speed of the garment sewing lining.

[0079] When the current sewing mode is a turning sewing mode, the correspondence between sewing speed and laying speed is as follows:

[0080]

[0081] in, The laying speed in the turning sewing mode is expressed in m / s; 'a' is a setting coefficient. The initial sewing speed in the turning sewing mode, in m / s; is the final speed in turning sewing mode, in m / s; b is an empirical correction factor, 0 <b≤1。

[0082] The empirical correction factor 'b' primarily controls the situation during turns. Because if there is garment sewing lining in the fabric during a turn, the clamping assembly of the laying device may disengage and malfunction. Therefore, during turns, the clamping assembly is stopped rotating, thus halting the laying device's operation. This formula will... The speed controlled in real time is processed into an equivalent real-time speed that can be processed by a set coefficient a.

[0083] It is important to note the initial and final velocities. and The order cannot be changed. This improvement aims to directly construct a method that can be controlled by a set coefficient a using an empirical correction coefficient b, adjusting only the formula.

[0084] In the turning sewing mode, it is obtained through detection. and Then use the formula Calculate the laying speed in the turning sewing mode to ensure that the sewing speed of the underline in the turning sewing mode matches the laying speed of the garment sewing lining.

[0085] It is important to note that in the turning sewing mode, there is no relative displacement between the needle-punching mechanism and the laying device. The laying speed of the garment sewing interlining laying device should approach zero when turning, while the sewing speed will decrease and the direction will change to ensure that the garment sewing interlining is not sewn into the stitches of the top thread.

[0086] The above-described laying speed control method, after determining the current laying speed corresponding to the current sewing speed, further includes the following steps:

[0087] Calculate the target rotational speed of the laying drive motor based on the current laying speed;

[0088] Get the current speed of the laying drive motor;

[0089] Determine whether the target speed is consistent with the current speed. If so, control the laying drive motor to operate at the current speed; otherwise, adjust the current speed of the laying drive motor to the target speed.

[0090] This invention uses a closed-loop control method to adjust the current speed of the laying drive motor in real time according to the laying speed, so that the laying drive motor keeps the current speed consistent with the target speed, thereby ensuring that the actual laying speed is consistent with the calculated ideal laying speed, avoiding errors in the sewing process and improving sewing quality.

[0091] Obtaining the current sewing speed specifically involves: first, using an image recognition device to acquire the current stitch size of the sewing thread; then, determining the current sewing speed based on the current stitch size. The image recognition device can be an infrared camera, etc., and is not specifically limited here. Of course, the method for obtaining the current sewing speed is not limited to this.

[0092] This invention also discloses a garment sewing lining laying device, applied to the above-mentioned laying speed control method, comprising:

[0093] It includes a fixed base 2, a clamping assembly 3, and a lifting and pressing assembly 4. The fixed base 2 is fixed to the machine head 1, as shown in the attached figure. Figure 2 As shown, the fixing base 2 provides support. (See attached diagram) Figures 3 to 5 As shown, the clamping assembly 3 is used to clamp the garment sewing interlining 5, which can be a horsehair interlining, etc. (See attached image.) Figure 11 As shown, the garment sewing interlining 5 involves continuously spreading radially brush-like material into the seam. Two to three brush-like materials are wrapped between each adjacent stitch, providing sufficient thread allowance to reduce shrinkage. The garment sewing interlining 5 is preferably horsehair interlining. Materials used to manufacture this horsehair interlining mainly include chemical fibers (polyester fibers, etc.), synthetic fibers, cellulose functional materials, polyester, resin interlining, PBT plastic, linen interlining, and nylon, possessing advantages such as good flexibility, tear resistance, adhesion, and abrasion resistance. PBT stands for polybutylene terephthalate.

[0094] The clamping assembly 3 is rotatably mounted on the fixed base 2, causing the clamping assembly 3 to drive the garment sewing interlining 5 to rotate relative to the fixed base 2. The lifting and pressing assembly 4 is fixed to the fixed base 2 and rotatably connected to the clamping assembly 3. It can both allow the clamping assembly 3 to rotate relative to the lifting and pressing assembly 4 and allow the lifting and pressing assembly 4 to lift or lower the clamping assembly 3, adjusting the relative position between the garment sewing interlining 5 and the top thread.

[0095] When in lining sewing mode, the lifting and pressing component 4 presses down the clamping component 3, meaning the clamping component 3 moves downward relative to the fixed base 2. The clamping component 3 pulls the garment lining 5 closer to the top seam. Simultaneously, the clamping component 3 continuously rotates relative to the fixed base 2, causing the clamped garment lining 5 to rotate synchronously. This achieves continuous laying of the garment lining 5 along the top seam, eliminating the need for manual laying and saving time and effort. The lining sewing mode mentioned in this text refers to the sewing machine being in the lining sewing mode.

[0096] When in normal sewing mode, the lifting and pressing component 4 raises the clamping component 3, meaning the clamping component 3 moves upward relative to the fixed base 2. The clamping component 3 pulls the clamped garment interlining 5 away from the top thread and stops rotating, thus stopping the laying of the garment interlining 5. The normal sewing mode mentioned in this text refers to the sewing machine being in the normal fabric sewing mode.

[0097] This invention designs a garment sewing interlining laying device that can continuously lay the garment sewing interlining 5 in interlining sewing mode and raise the garment sewing interlining 5 in normal sewing mode. That is, it can automatically and continuously lay the garment sewing interlining without affecting normal sewing. It has a high degree of automation, eliminates the need for manual laying of garment sewing interlining, saves time and labor in the production process, greatly reduces ineffective working time, and has high production efficiency.

[0098] As attached Figure 3 As shown, the clamping assembly 3 includes a rotating sleeve 31 and a clamping head 32. The rotating sleeve 31 is a hollow structure and is rotatably mounted to drive the clamping head 32 and the garment lining it holds to rotate synchronously. The clamping head 32 is slidably mounted at the end of the rotating sleeve 31, specifically at the end of the rotating sleeve 31 away from the drive cylinder. It is used to clamp the garment sewing lining 5 and drive the garment sewing lining 5 to slide relative to the rotating sleeve 31, thereby achieving floating lifting and pressing of the garment sewing lining 5 and ensuring the controllability of sewing mode switching.

[0099] As attached Figure 3 As shown, the free end of the rotating sleeve 31 has an oblong hole 311 extending along its axial direction, which serves as a guide. The free end in this text refers to the end of the rotating sleeve 31 furthest from the drive cylinder. (See attached image.) Figure 5 As shown, the clamping head 32 includes an upper clamping sleeve 321 and a lower clamping sleeve 322 that are coaxially nested and detachably connected, facilitating adjustment of the axial distance between the upper clamping sleeve 321 and the lower clamping sleeve 322. This allows for the clamping of garment sewing interlinings 5 ​​of different thicknesses between the upper clamping sleeve 321 and the lower clamping sleeve 322, providing good adaptability. (See attached...) Figure 4As shown, the upper sleeve 321 is stepped, with its small-diameter end fitted onto the rotating sleeve 31, and its large-diameter end nested with the lower sleeve 322. The end of the lower sleeve 322 exposed outside the upper sleeve 322 is integrally provided with a clamping flange, and an annular clamping groove is formed between the end faces of the clamping flange and the upper sleeve 321 for clamping the garment sewing lining 5.

[0100] The upper sleeve 321 is fixed with a guide pin 33 extending radially therefrom, the guide pin 33 passing through the oblong hole 311, so that the guide pin 33 guides the upper sleeve 321 to slide relative to the rotating sleeve 31. Of course, the floating connection between the rotating sleeve 31 and the clamping head 32 is not limited to this.

[0101] As attached Figures 3 to 5 As shown, the clamping assembly 3 includes an inner sliding sleeve 34, which is slidably disposed on the rotating sleeve 31. The central hole of the rotating sleeve 31 guides the inner sliding sleeve 34 to slide relative to the rotating sleeve 31 along the axial direction of the rotating sleeve 31. A guide pin 33 passes through the inner sliding sleeve 34, and the inner sliding sleeve 34 and the upper clamping sleeve 321 slide synchronously relative to the rotating sleeve 31 under the joint guidance of the guide pin 33 and the waist-shaped hole 311.

[0102] As attached Figure 4 and 5 As shown, the lifting and pressing assembly 4 includes a connecting shaft 41, which is a hollow structure and coaxially disposed within the rotating sleeve 31. The connecting shaft 41 and the inner sliding sleeve 34 are coaxially nested and rotate relative to each other, thereby causing the clamping assembly 3 to rotate relative to the lifting and pressing assembly 4. Of course, the rotational connection between the clamping assembly 3 and the lifting and pressing assembly 4 is not limited to this.

[0103] As attached Figure 5 and 8 As shown, an inner bearing 6 is provided between the connecting shaft 41 and the inner sleeve 34 to support the rotation of the inner sleeve 34 relative to the connecting shaft 41. The inner bearing 6 is located on the rotating sleeve 31. A shaft screw 42 is fixed to the end of the connecting shaft 41. The clamping assembly 3 also includes a bearing block 35 coaxially located inside the inner sleeve 34 and transversely located through the guide pin 33. The bearing block 35, the inner sleeve 34, the rotating sleeve 31, and the upper clamping sleeve 321 are arranged sequentially from the inside to the outside, and are connected by the radially passing guide pin 33. The bearing block 35 and the shaft screw 42 respectively abut against the outer ring and inner ring of the first end of the inner bearing 6. That is, the end face of the bearing block 35 abuts against the outer ring of the first end of the inner bearing 6 under the support of the guide pin 33, and the head of the shaft screw 42 abuts against the inner ring of the first end of the inner bearing 6, thereby achieving axial positioning of the first end of the inner bearing 6. A stop ring 341 is formed inside the inner sleeve 34, as shown in the attached figure. Figure 3 and 10As shown, the end faces of the stop ring 341 and the connecting shaft 41 respectively abut against the outer ring and inner ring of the second end of the inner bearing 6. That is, the end face of the stop ring 341 abuts against the outer ring of the second end of the inner bearing 6, and the end face of the connecting shaft 41 abuts against the inner ring of the second end of the inner bearing 6, thereby achieving axial positioning of the second end of the inner bearing 6. Of course, the positioning method of the inner bearing 6 is not limited to this.

[0104] As attached Figure 5 and 6 As shown, the lifting assembly 4 also includes a fixedly mounted lifting cylinder 43. The piston rod 431 of the lifting cylinder 43 is inserted into the rotating sleeve 31. The piston rod 431 and the connecting shaft 41 are elastically connected by an elastic element 44, as shown in the attached figure. Figure 5 and 7 As shown. In the lining sewing mode, the piston rod 431 of the lifting cylinder 43 extends outward, the elastic element 44 is stretched, and the piston rod 431 pushes the clamping head 32 downward relative to the rotating sleeve 31 through the connecting shaft 41, pressing down the garment sewing lining 5. In the normal sewing mode, the piston rod 431 of the lifting cylinder 43 retracts, the elastic element 44 recovers its elastic deformation, and the elastic element 44 drives the piston rod 431 to quickly move upward and reset by elastic force. The connecting shaft 41 drives the clamping head 32 to move upward relative to the rotating sleeve 31, lifting the garment sewing lining 5. The elastic element 44 is designed to assist the piston rod 431 in quickly resetting. The elastic element 44 can be a cylindrical spring, but is not limited to this. The cylinder of the lifting cylinder 43 is connected to an air pipe connector 432, which is connected to an external air supply pipe to supply air to the lifting cylinder 43.

[0105] As attached Figure 6 and 8 The connecting shaft 41 has an elongated hole 411 on its side wall, which extends axially along the connecting shaft 41. The elastic element 44 is equipped with a hook for moving away from the piston rod 431, and the hook is engaged within the elongated hole 411. The elongated hole 411 reduces the assembly difficulty between the connecting shaft 41 and the elastic element 44. To prevent the elastic element 44 from detaching from the connecting shaft 41, an annular groove 412 is provided on the outer surface of the connecting shaft 41. An elastic retaining ring 45 is fixed within the annular groove 412, abutting against the hook and pressing it to ensure a reliable connection between the elastic element 44 and the connecting shaft 41.

[0106] As attached Figure 3As shown, the above-mentioned garment sewing lining laying device also includes a laying drive motor 7 and a transmission mechanism 8 connected to the laying drive motor 7. The transmission mechanism 8 includes a drive pulley 81, a driven pulley 82, and a synchronous belt 83. The laying drive motor 7 is fixedly connected to the drive pulley 81, the driven pulley 82 is fixedly sleeved on the outside of the rotating sleeve 31, and the synchronous belt 83 is wound between the drive pulley 81 and the driven pulley 82. The torque of the laying drive motor 7 is transmitted from the drive pulley 81 to the driven pulley 82 through the synchronous belt 83, causing the drive pulley 81 to drive the driven pulley 82 to rotate, which in turn causes the driven pulley 82 to drive the rotating sleeve 31 to rotate, thus causing the clamping assembly 3 to rotate. The transmission mechanism 8 serves to reduce speed and can be replaced by a gear transmission mechanism or a sprocket transmission mechanism, etc., without specific limitation here. The driven pulley 82 and the rotating sleeve 31 are preferably connected by an interference fit to keep them rotating synchronously.

[0107] As attached Figure 2 and 3 As shown, the above-mentioned garment sewing lining laying device also includes a motor base 9 and a cylinder base 10. The motor base 9 is fixedly connected to the fixed base 2 and is used to support the laying drive motor 7. The cylinder base 10 is fixed to the motor base 9 and is used to support the lifting cylinder 43, ensuring that the lifting cylinder 43 is reliably fixed. At least one spring pin 13 is inserted between the fixed base 2 and the motor base 9 to fix the fixed base 2 to the motor base 9. The motor base 9 is fixed to the machine head 1 by fastening screws.

[0108] As attached Figure 5 As shown, an outer bearing 11 is provided between the fixed base 2 and the rotating sleeve 31 to support the rotation of the rotating sleeve 31 relative to the fixed base 2. Considering the weight of the clamping assembly 3 and the weight of the garment sewing lining 5, two outer bearings 11 are preferably provided between the fixed base 2 and the rotating sleeve 31. Of course, the number of outer bearings 11 is not limited to this. A limiting screw 12 is fixedly provided at the bottom of the fixed base 2. The limiting step 312 and the limiting screw 12 abut against the inner and outer rings at the bottom of the outer bearing 11, respectively. That is, the end face of the limiting step 312 abuts against the inner ring at the bottom of the outer bearing 11, and the head of the limiting screw 12 abuts against the outer ring at the bottom of the outer bearing 11, realizing the axial movement of the outer bearing 11. A limiting sleeve is fixedly fitted on the outer side wall of the rotating sleeve 31. The limiting sleeve abuts against the inner and outer rings at the top of the outer bearing 11, so that the limiting sleeve and the limiting screw 12 together limit the movement of the outer bearing 11 along its own axial direction. Of course, the limiting method of the outer bearing 11 is not limited to this.
