Description

Technical Field

[0001] This utility model belongs to the field of sewing machine equipment technology, specifically relating to a fabric sewing device for sewing collar fabric. Background Technology

[0002] In the garment manufacturing industry, the level of automation and intelligence of sewing equipment directly affects production efficiency and product quality. With rising labor costs and increasing consumer demands for garment quality, especially for complex components such as collars that require strict shape and size requirements, traditional sewing equipment suffers from technical bottlenecks such as low automation levels and low efficiency in multi-station collaboration, making it difficult to meet the demands for efficient and precise production.

[0003] Utility model patent application number CN202121151207.0 discloses a fabric processing equipment, including a turntable mechanism, a clamping mold device, a sewing mechanism, a cutting mechanism, and a feeding mechanism. The turntable mechanism includes a central turntable that rotates intermittently. The clamping mold device is mounted on the central turntable. Feeding, sewing, cutting, and feeding stations are sequentially arranged along the rotational conveying path of the central turntable. The sewing, cutting, and feeding mechanisms are respectively positioned at the sewing, cutting, and feeding stations. This fabric processing equipment achieves fully automated operation of collar fabric from cutting and sewing to feeding, avoiding the problem of inconsistent fabric specifications caused by manual sewing and cutting, and improving processing efficiency.

[0004] However, the aforementioned fabric processing equipment also has some problems. First, its complex structure requires four stations to complete the fabric feeding, sewing, cutting, and unloading processes. This not only increases the manufacturing cost of the equipment but also increases the risk of damage to the central turntable, as it needs to rotate four times for each collar fabric piece. Second, the lack of precise positioning and fixation of the fabric at the clamping mold device allows it to shift or even fold under the influence of the workshop environment or external airflow. This requires manual adjustment and affects work efficiency. Third, the stitching of collars is U-shaped, while the sewing mechanism only supports linear motion, which cannot meet the requirements for collar sewing. Finally, the cutting mechanism does not address how to collect and organize the waste fabric after cutting. In conclusion, the aforementioned fabric processing equipment is not suitable for sewing collar fabrics, and a fully automatic fabric sewing machine specifically designed for collar sewing is needed.

Detailed Implementation

[0032] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, a further detailed description of this utility model is provided below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of this utility model. Rather, this utility model covers any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this utility model as defined in the claims. Furthermore, to provide the public with a better understanding of this utility model, certain specific details are described in detail in the following description of the utility model. Those skilled in the art can fully understand this utility model even without these detailed descriptions.

[0033] like Figure 1 and Figure 2 The fabric sewing equipment shown includes a work platform 1, characterized in that the work platform 1 is respectively provided with a feeding station 2, a sewing station 3, a discharging station 4, and a conveying station 5. In this embodiment, the fabric to be sewn is collar fabric. The collar fabric to be sewn is manually fed or automatically fed by a robotic arm at the feeding station 2, automatically sewn at the sewing station 3, and the sewn fabric is automatically unloaded at the discharging station 4. The conveying station 5 is located at the center of the work platform 1 and is responsible for conveying the collar fabric between the above-mentioned stations. According to the fabric conveying sequence, the feeding station 2, sewing station 3, and discharging station 4 are arranged circumferentially around the outer periphery of the conveying station 5.

[0034] like Figure 1 , Figure 2 , Figure 9 and Figure 10 As shown, a central turntable 9 is provided on the conveying station 5, and a second drive mechanism 10 is provided to drive the central turntable 9 to rotate 0~360° in the circumferential direction. The second drive mechanism 10 can be configured as a servo motor. A first clamping device 11 is provided on the central turntable 9. In this embodiment, the number of first clamping devices 11 is set to three, corresponding to the loading station 2, sewing station 3, and unloading station 4, respectively. Each of the three first clamping devices 11 includes an upper clamping plate 35, a lower clamping plate 36, and a fifth drive mechanism 37 for driving the upper clamping plate 35 and the lower clamping plate 36 to clamp the fabric. A clamping space for placing the fabric is formed between the upper clamping plate 35 and the lower clamping plate 36. A first anti-slip member 38 is provided on the outer edge of the upper clamping plate 35, and a second anti-slip member 39 is provided on the outer edge of the lower clamping plate 36 to increase the friction with the fabric, ensure effective clamping of the fabric, and prevent the fabric from shifting or falling, which would affect subsequent sewing processes.

[0035] In this embodiment, the lower clamping plate 36 is fixed to the central turntable 9. A third guide rail 40 is arranged longitudinally on the central turntable 9, and a first fixing plate 41 is slidably arranged on the third guide rail 40. Specifically, a first slider is arranged on the first fixing plate 41, and the first slider is slidably engaged with the third guide rail 40. A second fixing plate 42 is arranged on the first fixing plate 41, and a fourth guide rail 43 is arranged horizontally on the second fixing plate 42. A third fixing plate 44 is slidably arranged on the fourth guide rail 43, and a second slider is arranged on the third fixing plate 44, and the second slider is slidably engaged with the fourth guide rail 43. The upper clamping plate 35 is arranged on the third fixing plate 44.

[0036] The fifth drive mechanism 37 includes a fourth drive motor 45 mounted on the central turntable 9 for driving the first fixed plate 41 to move longitudinally, and a fifth drive motor 46 mounted on the second fixed plate 42 for driving the third fixed plate 44 to move horizontally. The fourth drive motor 45 is mounted on the central turntable 9, and its output shaft is connected to the first fixed plate 41; the fifth drive motor 46 is mounted on the second fixed plate 42, and its output shaft is connected to the third fixed plate 44. The second fixed plate 42 mainly serves to connect the first fixed plate 41 and the third fixed plate 44, mount the fourth guide rail 43, and mount the fifth drive motor 46.

[0037] The upper clamping plate 35 and lower clamping plate 36 of the first clamping device 11, rotated to the loading station 2, are converted from the open state to a clamping device. Specifically, after the collar fabric to be sewn is placed on the upper surface of the lower clamping plate 36, the fifth drive motor 46 drives the third fixing plate 44 to move the upper clamping plate 35 horizontally to above the lower clamping plate 36. Then, the fourth drive motor 45 drives the first fixing plate 41 to move the second fixing plate 42, the third fixing plate 44, and the upper clamping plate 35 downwards in the longitudinal direction until the lower surface of the upper clamping plate 35 contacts the fabric, and the fabric is clamped under the combined action of the upper clamping plate 35 and the lower clamping plate 36. Rotating to the sewing station The upper clamping plate 35 and lower clamping plate 36 of the first clamping device 11 at the sewing station 3 are always in a clamping state; when the first clamping device 11 at the unloading station 4 is rotated, the upper clamping plate 35 and lower clamping plate 36 change from the clamping state to the open state. Specifically, the first fixed plate 41 is driven by the fourth drive motor 45 to drive the second fixed plate 42, the third fixed plate 44 and the upper clamping plate 35 to move upward in the longitudinal direction until the lower surface of the upper clamping plate 35 separates from the fabric. Then, the third fixed plate 44 is driven by the fifth drive motor 46 to drive the upper clamping plate 35 to move in the horizontal direction away from the lower clamping plate 36, thereby releasing the fabric to facilitate unloading of the fabric.

[0038] The first clamping device 11, which is in the open state after unloading at the unloading station 4, rotates to the loading station 2 for reloading, and this cycle is repeated to achieve fully automatic and continuous fabric sewing processing. A fifth drive motor 46 is set up to drive the third fixed plate 44 to move the upper clamping plate 35 in the horizontal direction, which facilitates the loading process at the loading station 2. That is, during the loading process, there is no upper clamping plate 35 above the lower clamping plate 36 to block it, and there is enough space to complete the operation of placing the fabric to be sewn on the lower clamping plate 36.

[0039] like Figure 1 , Figures 9 to 13 As shown, to ensure the accuracy of the fabric placement and the overall flatness of the fabric during the feeding process, an adsorption device 47 is provided on the feeding station 2 in this embodiment. The adsorption device 47 includes a suction box 48 disposed below the lower clamping plate 36, and a sixth drive mechanism 49 for driving the suction box 48 to move in the longitudinal direction. The sixth drive mechanism 49 can be configured as a cylinder or a servo motor. To ensure the movement accuracy of the suction box 48, a guide plate is provided on the working platform 1. A first guide hole is opened on the guide plate, and a guide ring is disposed in the first guide hole. A first guide rod is disposed on the lower surface of the suction box 48 along the driving direction of the sixth drive mechanism 49. The first guide rod is inserted into the guide ring. Through the sliding cooperation between the first guide rod and the guide ring, the suction box 48 is guided to move in the longitudinal direction.

[0040] The upper surface of the suction box 48 is provided with a suction panel 65, on which a plurality of first air outlets 50 are sequentially opened. The lower clamping plate 36 is sequentially provided with a plurality of second air outlets 51, which correspond to the first air outlets 50. The lower surface of the suction box 48 is provided with a fourth through hole 55 for the suction nozzle 54 to pass through. One end of the suction nozzle 54 corresponds to the first air outlet 50, and the other end of the suction nozzle 54 is connected to a third fan through a third connecting pipe 56. The third fan can be configured as a vacuum cleaner or a suction fan. The third fan removes the air in the suction box 48, thereby giving the adsorption device 47 suction power. A sealing element 57 for preventing air leakage is provided between the fourth through hole 55 and the suction nozzle 54.

[0041] During fabric loading, the sixth drive mechanism 49 drives the suction box 48 to move upwards in the longitudinal direction until the upper surface of the suction panel 65 contacts the lower surface of the lower clamping plate 36. At this time, the several second air outlets 51 on the lower clamping plate 36 correspond to the first air outlets 50 and are interconnected. The fabric is placed according to the limiting piece 52 on the suction panel 65 that corresponds to the outer edge of the collar fabric. The part to be clamped is located on the upper surface of the lower clamping plate 36, and the part to be sewn is located on the upper surface of the suction panel 65. The fabric is adsorbed through the first air outlet 50 and the second air outlet 51, ensuring that the fabric will not shift or fold due to the workshop environment or external airflow. No manual re-adjustment is required, which can effectively save time and improve work efficiency. The suction panel 65 is also equipped with a sensor 53 corresponding to the upper clamping plate 35. After sensing that the upper clamping plate 35 is clamping the fabric, the sixth drive mechanism 49 drives the suction box 48 to move downward in the longitudinal direction so that the first clamping device 11 can rotate to the next work station.

[0042] like Figure 1 , Figure 2 and Figure 7 As shown, a sewing device and a cutting device are respectively provided on the sewing station 3. The sewing device includes a sewing machine 6 and a first drive mechanism 7 for driving the sewing machine 6 to move along the sewing stitch on the fabric. In this embodiment, since the fabric to be sewn is a collar, and its sewing stitch is U-shaped, the sewing machine 6 needs to move in the X-axis direction, move in the Y-axis direction, and rotate in the circumferential direction.

[0043] like Figure 1 , Figure 7 and Figure 8 As shown, a first guide rail 24 is arranged along the X-axis and a second guide rail 25 is arranged along the Y-axis on the work platform 1. A support base 26 is slidably arranged on the second guide rail 25. Specifically, the first guide rail 24 is installed on the work platform 1, and a third slider is slidably arranged on the first guide rail 24. A fifth fixing plate is arranged on the third slider. The second guide rail 25 is installed on the fifth fixing plate, and a fourth slider is slidably arranged on the second guide rail 25. The support base 26 is connected to the fourth slider. The sewing machine 6 rotates with the support base 26. Specifically, a third through hole 30 is opened on the support base 26 for the connecting shaft to pass through. A bearing is arranged between the connecting shaft and the third through hole 30, and the upper end of the connecting shaft is connected to the sewing machine 6.

[0044] The first drive mechanism 7 includes a first drive motor 27 mounted on the first guide rail 24 for driving the second guide rail 25 to move along the X-axis, a second drive motor 28 mounted on the second guide rail 25 for driving the support base 26 to move along the Y-axis, and a third drive motor 29 mounted on the support base 26 for driving the sewing machine 6 to rotate 0~180° in the circumferential direction. A first synchronous pulley is provided at the lower end of the connecting shaft, and a second synchronous pulley is provided on the output shaft of the third drive motor 29. A synchronous belt is provided between the first and second synchronous pulleys. According to the direction of the sewing stitch, the first drive motor 27, the second drive motor 28, and the third drive motor 29 drive the sewing machine 6 to move according to a preset program. After completing one sewing operation, the sewing machine 6 resets to prepare for the next sewing operation.

[0045] like Figure 3 , Figure 5 and Figure 6 As shown, the sewing machine 6 is equipped with a main shaft 12 and a third drive mechanism 13 for driving the main shaft 12 to rotate. The third drive mechanism 13 can be configured as a servo motor, and the third drive mechanism 13 is the main drive mechanism for the sewing operation of the sewing machine 6. The sewing needle 64 on the sewing machine 6 is connected to the main shaft 12 through a first cam mechanism.

[0046] like Figures 3 to 6 As shown, the cutting device includes a cutter 8 mounted on the sewing machine 6. The cutter 8 is connected to the main shaft 12 via a second cam mechanism, and the cutter 8 is located on the side of the needle 64 away from the first clamping device 11. The presser foot 14 of the sewing machine 6 is located between the needle 64 and the cutter 8. A first through hole 16 for the cutter 8 to pass through is provided on the panel 15 of the sewing machine 6. A base plate corresponding to the cutter 8 is provided in the first through hole 16, and the base plate can be replaced according to the degree of wear. In this embodiment, both the cutter 8 and the needle 64 are driven by a third drive mechanism 13. The rotation of the main shaft 12 is converted into the up-and-down reciprocating motion of the cutter 8 and the needle 64 through the first cam mechanism and the second cam mechanism, respectively, to ensure the synchronization of the cutter 8 and the needle 64. While the needle 64 of the sewing machine 6 is sewing the fabric, the cutter 8 cuts off the excess fabric at the outer edge of the fabric.

[0047] A connecting block 17 is provided on the cutter 8, and a slot 18 is provided on the side of the connecting block 17 away from the first clamping device 11. The second cam mechanism includes a cam 19 provided on the main shaft 12, a first connecting rod 20 arranged in the longitudinal direction and hinged to the upper end of the cam 19, and a second connecting rod 21 arranged in the horizontal direction and connected to the lower end of the first connecting rod 20. A second through hole is provided inside the second connecting rod 21 in its own axial direction, and a connecting rod 22 is movably arranged in the second through hole. One end of the connecting rod 22 corresponds to the slot 18. A fourth drive mechanism 23 is provided outside the second connecting rod 21. The fourth drive mechanism 23 can be a cylinder or a servo motor. Its output end is connected to the other end of the connecting rod 22 and is used to drive the connecting rod 22 to move in the axial direction of the second through hole, so that the connecting rod 22 is connected to or separated from the slot 18.

[0048] When the cutter 8 needs to cut off excess fabric at the outer edge of the fabric during the sewing process, the fourth drive mechanism 23 drives the connecting rod 22 to move towards the connecting block 17, so that the end of the connecting rod 22 is engaged in the slot 18, realizing the connection between the cutter 8 and the main shaft 12, and making the cutter 8 and the needle 64 move up and down synchronously; when the cutter 8 does not need to cut off excess fabric at the outer edge of the fabric during the sewing process, the fourth drive mechanism 23 drives the connecting rod 22 to move away from the connecting block 17, so that the end of the connecting rod 22 is separated from the slot 18, realizing the separation between the cutter 8 and the main shaft 12, so that the cutter 8 is no longer driven by the third drive mechanism 13.

[0049] like Figure 5 and Figure 6 As shown, the cutting device also includes an adjustment mechanism 66 for adjusting the longitudinal height of the cutter 8 to accommodate fabrics of different thicknesses. The adjustment mechanism 66 includes a pressure plate 67 located above the connecting block 17 and a ninth drive mechanism 68 for driving the pressure plate 67 to move longitudinally. The ninth drive mechanism 68 can be configured as a servo motor or a cylinder. A second guide hole is provided on the connecting block 17, and a second guide rod 69 is slidably inserted into the second guide hole along the longitudinal direction. An elastic element is sleeved on the second guide rod 69, and the elastic element is located between the lower surface of the pressure plate 67 and the upper surface of the connecting block 17. The elastic element can be configured as a tension spring. The ninth drive mechanism 68 drives the pressure plate 67 to drive the spring to adjust the longitudinal position of the connecting block 17, thereby determining the longitudinal height of the cutter 8.

[0050] like Figures 2 to 4As shown, the sewing machine head 6 is equipped with a blower 31 and a take-up device 32. The blower 31 has a first channel running through it for air to pass through. One end of the blower 31 corresponds to the cut fabric, and the other end of the blower 31 is connected to a first fan through a first connecting pipe. The first fan can be configured as a blower. The take-up device 32 has a second channel running through it for air to pass through. One end of the take-up device 32 is configured as a feed inlet 33, which is opposite to the blower 31. The other end of the take-up device 32 is connected to a second fan through a second connecting pipe 34. The second fan can be configured as a vacuum cleaner or a suction fan. By blowing material through the blower 31 and sucking material through the collector 32, waste fabric after being cut by the cutter 8 can be collected, realizing the three-in-one process of sewing, cutting and waste collection on the sewing station 3. This ensures that the panel 15 of the sewing machine 6 is clean and tidy, avoids manual collection of waste, and saves time and effort.

[0051] like Figure 1 , Figure 2 and Figure 14 As shown, a second clamping device 58 and a guide plate 59 are provided on the unloading station 4. The guide plate 59 is inclined and positioned below the second clamping device 58. The second clamping device 58 includes a gripper 60, a seventh drive mechanism for driving the gripper 60 to clamp or release the fabric, and an eighth drive mechanism 62 for driving the gripper 60 to reciprocate between the first clamping device 11 and the guide plate 59. A fourth fixed plate 63 is provided on the output shaft of the eighth drive mechanism 62, and the seventh drive mechanism is mounted on the fourth fixed plate 63. The gripper 60 is connected to the output shaft of the seventh drive mechanism. The seventh drive mechanism can be configured as a thumb cylinder, and the eighth drive mechanism 62 can be configured as a cylinder or a servo motor.

[0052] When the first clamping device 11 rotates to the unloading station 4 and changes from the clamping state to the open state, the eighth drive mechanism 62 drives the fourth fixing plate 63 to move the seventh drive mechanism and the gripper 60 toward the first clamping device 11 until the gripper 60 contacts the fabric. The seventh drive mechanism drives the gripper 60 to clamp the outer edge of the fabric. Then, the eighth drive mechanism 62 drives the fourth fixing plate 63 to move the seventh drive mechanism and the gripper 60 away from the first clamping device 11, and the seventh drive mechanism drives the gripper 60 to release the fabric, so that the fabric falls onto the guide plate 59 and enters the receiving cylinder through the guide plate 59.
