Description

Technical Field

[0001] This invention relates to the field of garment processing equipment technology, and in particular to a turning device, a sewing production line, and a method for turning sewn products. Background Technology

[0002] Based on existing garment sewing methods, it is necessary to first sew along the edges of the overlapping areas of the front panel located in front of the body and the back panel located behind the body, which is called the "edge seam" of the garment. After the edge seam is completed, the hem, cuffs, collar, etc. of the garment are then sewn.

[0003] In related technologies, technicians need to manually turn the garment inside out after the "side seam" is completed before putting it on the hem machine, which results in very low production efficiency. Summary of the Invention

[0007] The opening mechanism is used to drive at least one of a portion of the first fabric layer and a portion of the second fabric layer to move away from each other, thereby enlarging the first opening.

[0008] The flipping mechanism is used to extend into the sewn product through the first opening, contact the second end of the sewn product along the first direction, and drive the second end of the sewn product to pass through the first opening, thereby flipping the sewn product.

[0009] The opening mechanism is used to drive the first end to move so that the first end faces the fitting mechanism after the sewn product is turned over.

[0010] The fitting mechanism is used to move the sewn product toward the processing mechanism of the next process after the first end is facing the fitting mechanism, so that the first opening is fitted onto the processing mechanism.

[0011] The aforementioned flipping device has an opening mechanism that fixes the first and second fabric layers respectively, making the first opening larger. The flipping mechanism drives the second end to pass through the first opening to achieve flipping. Finally, the fitting mechanism fits the flipped sewn product onto the processing mechanism of the next process, completely replacing manual operation and improving production efficiency.

[0012] In some embodiments, the opening mechanism includes a clamping mechanism and a fixing mechanism;

[0018] In some embodiments, the fixing mechanism includes a first driving member and a second lifting assembly. The third bracket is mounted on the first bracket via the second lifting assembly. The first driving member is mounted on the third bracket and connected to the second gripper assembly. The second lifting assembly is used to drive the third bracket to move along the first direction. The first driving member is used to drive the second gripper assembly to rotate the sewn product around the third bracket so that the first end faces the fitting mechanism.

[0019] In some embodiments, the flipping mechanism includes a fourth bracket and a fixing part. The fourth bracket includes a fixed bracket, a telescopic bracket, and a second driving member. The second driving member and the telescopic bracket are disposed on the fixed bracket. The second driving member is connected to the telescopic bracket and is used to drive the telescopic bracket to move along the first direction on the fixed bracket. The fixed bracket is fixed on the first bracket. The fixing part is disposed at one end of the telescopic bracket near the sewn product and is used to contact the second end.

The air nozzle communicates with the air storage device, and the air nozzle is used to spray high-pressure gas onto the sewn product when it is mounted onto the processing mechanism of the processing device.

[0021] An embodiment of the present invention provides a sewing production line including the flipping device described above.

[0022] An embodiment of the present invention provides a method for turning over a sewn garment, the sewn garment comprising a first fabric layer and a second fabric layer stacked together, the edges of the first fabric layer and the edges of the second fabric layer being connected, and a first opening being formed at a first end of the sewn garment along a first direction; the method for turning over includes:

[0023] The control opening mechanism drives at least one of a portion of the first fabric layer and a portion of the second fabric layer to move away from each other, thereby enlarging the first opening;

[0024] The control flipping mechanism extends into the sewn product from the first opening, contacts the second end of the sewn product along the first direction, and drives the second end of the sewn product to pass through the first opening, thereby flipping the sewn product.

[0025] After the sewn product is turned over, the opening mechanism is controlled to drive the first end to move so that the first end faces the fitting mechanism;

[0026] After the first end of the fitting mechanism is aligned with the fitting mechanism, the first end drives the sewn product to move toward the processing mechanism of the next process so that the first opening is fitted onto the processing mechanism.

[0048] Please see Figure 1 The present invention provides a flipping device 100 for processing sewn products. The sewn products include a first fabric layer and a second fabric layer stacked together. The edges of the first fabric layer and the edges of the second fabric layer are connected. A first opening is formed at a first end of the sewn products along a first direction.

[0049] The flipping device 100 includes an opening mechanism 10, a flipping mechanism 12, a fitting mechanism 14, and a first support 16, wherein the opening mechanism 10, the flipping mechanism 12, and the fitting mechanism 14 are mounted on the first support 16.

[0050] The opening mechanism 10 is used to drive at least one of a portion of the first fabric layer and a portion of the second fabric layer to move away from each other, thereby enlarging the first opening.

[0051] The flipping mechanism 12 is used to extend into the sewn product from the first opening, contact the second end of the sewn product along the first direction, and drive the second end of the sewn product to pass through the first opening, so as to flip the sewn product.

[0052] The opening mechanism 10 is used to drive the first end to contact the first end with the sewing mechanism 14 after the sewn product is turned over.

[0053] The fitting mechanism 14 is used to move the sewn product toward the processing mechanism of the next process after contacting the first end, so that the first opening is fitted onto the processing mechanism.

[0054] The aforementioned flipping device 100 and opening mechanism 10 respectively fix the first fabric layer and the second fabric layer, making the first opening larger. The flipping mechanism 12 drives the second end to pass through the first opening to achieve flipping. Finally, the fitting mechanism 14 fits the flipped sewn product onto the processing mechanism of the next process, completely replacing manual operation and improving production efficiency.

[0055] Specifically, based on existing garment sewing methods, it is necessary to first sew along the edges of the overlapping areas of the front panel located in front of the body and the back panel located behind the body, which is the "edge seam" of the garment. After the edge seam is completed, the hem, cuffs, collar, etc. of the garment are then sewn.

[0056] Garments that have undergone edge seaming need to be turned inside out before proceeding to the next process. In related technologies, this requires manual operation to turn the garment inside out and then attach it to the hem-mounting machine. Therefore, the sewing production line 200 must be staffed with operators to perform the turning and attaching of the garments, resulting in very low production efficiency.

[0057] To address the aforementioned problems, this invention provides a flipping device 100 for flipping the inner and outer surfaces of sewn products.

[0058] The sewn product includes a first fabric layer and a second fabric layer stacked together, and the opposite sides of the first fabric layer and the second fabric layer are connected by side seams, so that the edges of the first fabric layer and the edges of the second fabric layer are connected. The sewn product has a first opening at a first end along a first direction.

[0059] The opening mechanism 10 enlarges the first opening of the sewn product. The turning mechanism 12 extends into the first opening and drives the second end of the sewn product to extend out of the first opening to complete the turning. At the same time, the opening mechanism 10 and the fitting mechanism 14 cooperate to adjust the turning direction of the sewn product after turning, so that the fitting mechanism 14 can fit the sewn product onto the processing mechanism of the next process.

[0060] In one embodiment, the turning device 100 is used to turn the garment with the edge seams completed and then fit it onto the hem sewing machine for hem sewing. First, the edge seam device 110 performs edge seams on the garment, then the turning device 100 turns it over, and then the turned-over garment is fitted onto the hem sewing device 120 for the next process. Thus, the turning device 100 can automatically complete the turning and fitting process of the garment before hem processing, which can replace manual operation and achieve automation.

[0061] In the text Figure 1 The positive and negative directions of the X-axis are described as the first direction, the positive and negative directions of the Z-axis are described as the second direction, and the positive and negative directions of the Y-axis are described as the third direction.

[0062] Please see Figures 1 to 3 In some embodiments, the opening mechanism 10 includes a clamping mechanism 18 and a fixing mechanism 20. The clamping mechanism 18 is used to fix and move the first fabric layer to enlarge the first opening. The fixing mechanism 20 is used to fix the second fabric layer when the first opening is enlarged, and to move the first end toward the fitting mechanism 14 after the sewn product is turned over.

[0063] Thus, the clamping mechanism 18 fixes the first fabric layer, and the fixing mechanism 20 fixes the second fabric layer. By moving the clamping mechanism 18 or the fixing mechanism 20, the fabric layer can be moved, thereby enlarging the first opening.

[0064] Specifically, the opening mechanism 10 includes a clamping mechanism 18 and a fixing mechanism 20. The clamping mechanism 18 is used to fix or move a portion of the first fabric layer, and the fixing mechanism 20 is used to fix and move a portion of the second fabric layer, thereby making the first opening formed by the connection of the edges of the first and second fabric layers larger.

[0065] Please see Figure 2 In some embodiments, the clamping mechanism 18 includes a second bracket 22, a first lifting component 24 and a clamping component 26. The second bracket 22 is disposed on the first bracket 16 via the first lifting component 24, and the clamping component 26 is disposed on the second bracket 22. The first lifting component 24 is used to drive the second bracket 22 to move along a first direction.

[0066] Thus, the clamping component 26 is mounted on the second bracket 22, and the first lifting component 24 can drive the second bracket 22 and the clamping component 26 to move on the first bracket 16, thereby enabling the clamping mechanism 18 to move the first fabric layer to enlarge the first opening.

[0067] Specifically, after the clamping component 26 fixes the first fabric layer, the first lifting component 24 drives the second bracket 22 and the clamping component 26 to move away from the second fabric layer, thereby enlarging the first opening.

[0068] In the illustrated embodiment, the first lifting component 24 is used to move the second bracket 22 and the clamping component 26 along the second direction, so that the clamping component 26 can contact and fix the first fabric layer, and move the first fabric layer away from the second fabric layer, thereby enlarging the first opening.

[0069] Please see Figure 2 In some embodiments, the gripping assembly 26 includes a needle suction cup 27 and a first gripper assembly 28, wherein the needle suction cup 27 is used to separate the first fabric layer and the second fabric layer, and the first gripper assembly 28 is used to fix the first fabric layer.

[0070] In this way, the needle suction cup 27 can separate the stacked first and second fabric layers, and then the first gripper assembly 28 can grasp the first fabric layer to fix it.

[0071] Specifically, after the sewn product completes the previous process and is transported to the flipping device 100, the first lifting component 24 drives the clamping component 26 to descend along the second direction via the second bracket 22, moving until the needle suction cup 27 contacts the first fabric layer of the sewn product. The needle suction cup 27 controls the needle to extend and pierce the first fabric layer. The first lifting component 24 drives the clamping component 26 to rise along the second direction, and the needle suction cup 27 drives the first fabric layer to rise, stopping after reaching a certain distance. At this time, the first gripper component 28 is controlled to move, fixing the first fabric layer.

[0072] It should be noted that the needle-type suction cup 27 lifts the first fabric layer a certain distance, thus enlarging the first opening. The first gripper assembly 28 also needs a certain height when fixing the first fabric layer to avoid interference with other components on the flipping device 100. Simultaneously, the height at which the gripping assembly 26 lifts the first fabric layer needs to be appropriate to avoid lifting it too far, which could cause the second fabric layer to rise simultaneously with the first fabric layer via its edge, preventing the subsequent fixing mechanism 20 from securing the second fabric layer.

[0073] The specific value of the distance by which the needle suction cup 27 drives the first fabric layer to rise needs to be set according to the size and assembly relationship of each component of the flipping device 100 and the specifications of the sewn product, and is not limited here.

[0074] The first fabric layer is extracted by inserting the needle suction cup 27 into the fabric. The degree of insertion into the fabric can be controlled by adjusting the distance of the needle extension, thereby preventing the needle suction cup 27 from inserting into the first and second fabric layers at the same time.

[0075] In one embodiment, the gripping assembly 26 includes two or more needle-type suction cups 27. After the needle-type suction cups 27 pierce the first fabric layer, the first fabric layer rises synchronously with the needle-type suction cups 27. The two or more needle-type suction cups 27 together fix the first fabric layer, which can effectively prevent the first fabric layer from detaching from the needle-type suction cups 27.

[0076] Please see Figure 2 In one embodiment, the first gripper assembly 28 includes an upper fixing member 28a and a lower clamping member 28b, the lower clamping member 28b being rotatably connected to the upper fixing member 28a. The upper fixing member 28a is movable up and down in a first direction, and the lower clamping member 28b is rotatable about a fixing point to move closer to or away from the upper fixing member 28a. When the lower clamping member 28b moves closer to the upper fixing member 28a about the fixing point and the upper fixing member 28a moves downward, i.e., the upper fixing member 28a and the lower clamping member 28b move closer to each other, the fabric can be clamped and fixed between the upper fixing member 28a and the lower clamping member 28b. When the lower clamping member 28b moves away from the upper fixing member 28a about the fixing point and the upper fixing member 28a moves upward, i.e., the upper fixing member 28a and the lower clamping member 28b move away from each other, the fabric is released.

[0077] Please see Figures 3 to 5 In some embodiments, the fixing mechanism 20 includes a support plate 30 mounted on the first bracket 16 and used to place the sewn product. The flipping device 100 includes a mop assembly 31 mounted on the first bracket 16 and used to lay the sewn product flat on the support plate 30.

[0078] In this way, the accuracy of the flipping device 100% can be guaranteed.

[0079] Specifically, the support plate 30 is used to receive the sewn product that has been processed in the previous process and transferred to the flipping device 100. The mop assembly 31 includes a first direction drive member 31a, a second direction drive member 31b, and a mop plate assembly. The first direction drive member 31a and the second direction drive member 31b are used to drive the mop plate assembly to move in the first and second directions. The mop plate assembly includes a pressure plate 31c and an air blowing pipe 31d. The pressure plate 31c is fixedly installed with the first direction drive member 31a, and the air blowing pipe 31d is installed on the pressure plate 31c. The air blowing pipe 31d blows gas in the first direction. When the sewn product is transferred to the position of the support plate 30, the first direction drive member 31a and the second direction drive member 31b drive the mop plate assembly to move above the sewn product and press it against the sewn product. Then, the air blowing pipe 31d provides gas in the first direction to flatten the sewn product, remove wrinkles, and make the first end of the sewn product flat on the support plate 30 for subsequent operation of the clamping mechanism 18 and the fixing mechanism 20.

[0080] Using the mop assembly 31 to arrange and flatten the sewn products transferred to the support plate 30 can prevent the gripping mechanism 18 or the fixing mechanism 20 from failing to contact the sewn products due to wrinkles, folds, or other reasons when the sewn products are transferred to the support plate 30, thereby improving the accuracy of the operation of the flipping device 100.

[0081] In one embodiment, the support plate 30 further includes a needle suction cup 27. When the needle suction cup 27 is extended, it can extend from below the second fabric layer and pierce into the second fabric layer to prevent the second fabric layer from moving together with the first fabric layer when the clamping mechanism 18 moves the first fabric layer upward.

[0082] In some embodiments, the fixing mechanism 20 includes a second gripper assembly 32 and a third support 34, the third support 34 being disposed on the first support 16, the second gripper assembly 32 being disposed on the third support 34, and the second gripper assembly 32 being used to fix the second fabric layer.

[0083] Thus, the second fabric layer is fixed by the second gripper assembly 32, keeping the first opening stably open.

[0084] Specifically, after the clamping mechanism 18 moves the first fabric layer upward to enlarge the first opening, the fixing mechanism 20 fixes the second fabric layer through the second gripper assembly 32. Thus, the clamping mechanism 18 fixes the first fabric layer, the fixing mechanism 20 fixes the second fabric layer, and the first opening remains stably open.

[0085] Please see Figure 3 and Figure 5 In one embodiment, the support plate 30 has two first grooves 30a and two second grooves 30b. The fixing device includes two second gripper assemblies 32. The gripping mechanism 18 includes a third-direction drive member and a guide rail. The second gripper assemblies 32 are driven by the third-direction drive member to move on the guide rail. The guide rail and the support plate 30 are arranged substantially parallel to each other along the third direction.

[0086] When the second gripper assembly 32 is in its initial position, both second gripper assemblies 32 are located in the middle of the guide rail, with the openings of the second gripper assemblies 32 facing the positive direction of the second direction. During operation, the third-direction drive unit drives the second gripper assemblies 32 to move along the third direction to positions corresponding to the second slots 30b. At this time, the second gripper assemblies 32 rotate in the second slots 30b, adjusting the openings of the grippers to face the negative direction of the first direction. The support plate 30 and the second fabric layer are then gripped by the second gripper assemblies 32. The second gripper assemblies 32 then move along the third direction towards the first slot 30a, and in the first direction to align with the first slot 30a. The two second gripper assemblies 32 grip the second fabric layer in the two first slots 30a respectively. Thus, the support plate 30 can support the sewn product, and the opening of the first slots 30a and second slots 30b prevents interference between the support plate 30 and the second gripper assemblies 32 when they are rotated.

[0087] By clamping the second fabric layer at the second slot 30b position and then moving it to the first slot 30a position, it is possible to avoid touching the second fabric layer directly at the 30a position, which could cause wrinkles or prevent the second fabric layer from being fully clamped.

[0088] Please see Figure 4 In one embodiment, the second gripper assembly 32 includes an upper gripper 32a and a lower gripper 32b. The upper gripper 32a is movably connected to the lower gripper 32b. When the upper gripper 32a approaches the lower gripper 32b, the fabric can be clamped and fixed between the upper gripper 32a and the lower gripper 32b. When the upper gripper 32a moves away from the lower gripper 32b, the fabric is released. Furthermore, the portion of the upper gripper 32a and / or the lower gripper 32b that contacts the fabric also includes a flexible clamping block 32c. The flexible clamping block 32c allows the gripper assembly to clamp the fabric more firmly, while also providing some protection to the clamped fabric.

[0089] Please see Figure 6 In some embodiments, the flipping mechanism 12 includes a fourth bracket 36 and a fixing part 38. The fourth bracket 36 includes a fixed bracket 40, a telescopic bracket 42, and a second driving member 46. The second driving member 46 and the telescopic bracket 42 are disposed on the fixed bracket 40. The second driving member 46 is connected to the telescopic bracket 42 and is used to drive the telescopic bracket 42 to move along a first direction on the fixed bracket 40. The fixed bracket 40 is fixed on the first bracket 16. The fixing part 38 is disposed at one end of the telescopic bracket 42 near the sewn product and is used to contact the second end.

[0090] Thus, the flipping mechanism 12 extends into the interior of the sewn product through the first opening, contacts and drives the second end of the sewn product to pass through the first opening, thereby flipping the sewn product.

[0091] Specifically, the flipping mechanism 12 includes a fourth bracket 36 and a fixing part 38. The fourth bracket 36 can extend and retract to drive the fixing part 38 to move along the first direction, so that the fixing part 38 can be applied to sewn products of different specifications and can extend into and contact the second end of the sewn product from the first opening of the sewn product.

[0092] After the first opening is opened, the flipping mechanism 12 extends into the inside of the sewn product through the first opening, contacts and drives the second end of the sewn product to move along the first direction, and passes out through the first opening, thereby flipping the inner side of the sewn product into the outer side.

[0093] In one embodiment, the fixing part 38 of the turning mechanism 12 is L-shaped. When the L-shaped fixing part 38 hooks onto the neckline of the garment, it can contact and pull the garment out through the first opening. The sewn garment is a garment with the edge seams completed, with the first end being the hem and the second end being the neckline. The first and second fabric layers of the garment hem are fixed and moved by the clamping mechanism 18 and the fixing mechanism 20 to open the first opening at the hem. The turning mechanism 12 extends into the first opening at the hem, and the fixing part 38 contacts and hooks onto the neckline of the garment, thereby pulling the garment out through the first opening at the neckline, completing the turning of the garment.

[0094] In other embodiments, the fixing part 38 of the flipping mechanism 12 can be a two- or multi-finger gripper that grasps the sewn garment when it contacts the second end of the garment, thereby making contact with and driving the garment through the first opening.

[0095] In some embodiments, the fixing mechanism 20 includes a first driving member 44 and a second lifting assembly 48. The third bracket 34 is mounted on the first bracket 16 via the second lifting assembly 48. The first driving member 44 is mounted on the third bracket 34 and connected to the second gripper assembly 32. The second lifting assembly 48 is used to drive the third bracket 34 to move in a first direction. The first driving member 44 is used to drive the second gripper assembly 32 to rotate the sewn product around the third bracket 34 so that the first end faces the fitting mechanism 14.

[0096] In this way, the fixing mechanism 20 can adjust the position of the sewn product to achieve docking with the fitting mechanism 14.

[0097] Specifically, the second lifting assembly 48 drives the third support 34 and the second gripper assembly 32 mounted on the third support 34 to move along the first direction. After flipping, the gripping mechanism 18 releases the first fabric layer, and the first driving member 44 drives the second gripper assembly 32 to rotate 90 degrees, so that the first opening faces the fitting mechanism 14. The fixing mechanism 20 is driven by the second lifting assembly 48 and moves along the first direction until it reaches a position where the fitting mechanism 14 can acquire the sewn product, waiting for the fitting mechanism 14 to acquire the sewn product.

[0098] Please see Figure 7 In some embodiments, the fitting mechanism 14 includes a fifth support 54, a third gripper assembly 50, and a third drive member 52. The fifth support 54 is mounted on the first support 16 via the third drive member 52. The third gripper assembly 50 is mounted on the fifth support 54. The third drive member 52 is used to drive the third gripper assembly 50 to move along a first direction to obtain the sewn product and to move the sewn product onto the processing mechanism of the processing device. The third gripper assembly 50 includes an air blowing device, which includes an air nozzle 56 and an air storage device. The air nozzle 56 is connected to the air storage device and is used to spray high-pressure gas onto the sewn product when it is mounted on the processing mechanism of the processing device.

[0099] In this way, the fitting mechanism 14 and the fixing mechanism 20 work together to adjust the state of the sewn product after it has been turned over, so that the fitting mechanism 14 can smoothly fit the sewn product onto the processing mechanism of the next processing device.

[0100] Specifically, after the flipping mechanism 12 flips the sewn product, the fixing mechanism 20 holds the second fabric layer in place and rotates the second fabric layer 90 degrees so that the first opening faces the fitting mechanism 14. The fixing mechanism 20 is driven by the second lifting component 48 and moves along the first direction until it reaches the position where the fitting mechanism 14 can acquire the sewn product.

[0101] Please see Figure 1 The flipping device 100 and the processing mechanism for the next process are arranged along the first direction, and the fitting mechanism 14 is positioned above the fixing mechanism 20. The fixing mechanism 20 moves the sewn product along the second direction between the third gripper assembly 50 of the fitting mechanism 14 and the processing mechanism for the next process. The fitting mechanism 14 moves towards the processing mechanism along the first direction, allowing the third gripper assembly 50 to contact the second fabric layer of the sewn product. At this time, the third gripper assembly 50 fixes the second fabric layer, and the fixing mechanism 20 moves downward. At this point, the sewn product is in a state where the second fabric layer at the first end is fixed to the third gripper assembly 50, and the first fabric layer hangs down naturally, so that the first opening faces the processing mechanism of the next processing device. The third drive assembly drives the third gripper assembly 50 to move along the first direction, so that the first opening is fitted onto the processing mechanism.

[0102] Please see Figure 8 The air blowing device is used to blow high-pressure gas onto the sewn product after the sewn product is placed on the processing mechanism by the fitting mechanism 14, so as to straighten the sewn product and make it flatly placed on the processing mechanism.

[0103] In one embodiment, the flipping device 100 includes a sweeping cloth assembly 60, and the flipping mechanism 12 includes a cover plate 62. After the flipping mechanism 12 extends into the sewn product from the first opening, it drives the second end of the sewn product to pass through the first opening. At this time, the cover plate 62 is used to place the second end of the sewn product.

[0104] After acquiring the sewn product, the fitting mechanism 14 begins operation upon receiving a fitting instruction from the hem sewing device 120. An inspection position is established between the fitting mechanism 14 and the hem sewing device 120. The fitting mechanism 14 moves the sewn product toward the hem sewing device 120 along a first direction. Before fitting the sewn product onto the hem sewing device 120, the fitting mechanism 14 stops at the inspection position. The sweeping assembly 60 moves along the cover plate 62, sweeping away any portion of the sewn product that may still be draped over the cover plate 62, allowing the second end of the sewn product to hang naturally. After sweeping away any remaining portion of the sewn product from the cover plate 62 at the inspection position, the fitting mechanism 14 is then controlled to fit the first end onto the hem sewing device 120. This prevents interference at the second end of the sewn product when the fitting mechanism 14 fits the first end onto the processing mechanism.

[0105] In one embodiment, to prevent the second end of the sewn garment from getting caught on the fixing part 38, the cover plate 62 is wider on the side facing the edge sewing device 110, such as... Figure 6 As shown, this facilitates the removal of the second end of the sewn garment from the fixing part 38.

[0106] In one embodiment, the third gripper assembly 50 includes an upper gripper 28a and a lower gripper 28b. The upper gripper 28a is movably connected to the lower gripper 28b. When the upper gripper 28a approaches the lower gripper 28b, the fabric can be clamped and fixed between the upper gripper 28a and the lower gripper 28b. When the upper gripper 28a moves away from the lower gripper 28b, the fabric is released.

[0107] Furthermore, the portion of the upper gripper 28a and / or the lower gripper 28b that contacts the fabric also includes a flexible clamping block 32c. The flexible clamping block 32c can make the gripper assembly clamp the fabric more firmly, while also providing a certain degree of protection for the clamped fabric.

[0108] In summary, the opening mechanism 10 enlarges the first opening of the sewn product, and the turning mechanism 12 extends into the first opening and drives the second end of the sewn product to extend out of the first opening to complete the turning. At the same time, the opening mechanism 10 and the fitting mechanism 14 cooperate to adjust the turning direction of the sewn product after turning, so that the fitting mechanism 14 can fit the sewn product onto the processing mechanism of the next process, so that the turning device 100 can completely replace manual operation and improve production efficiency.

[0109] The movement of each mechanism on the aforementioned flipping device 100 can be positioned and detected by setting photoelectric switches. Meanwhile, the driving method of the aforementioned driving components can be any of pneumatic, hydraulic, and electric, without specific limitations.

[0110] Please see Figure 1A sewing production line 200 according to an embodiment of the present invention includes the flipping device 100 of the above embodiment.

[0111] Specifically, the sewing production line 200 may include an edge-sewing device 110, a turning device 100, and a hem-sewing device 120. The edge-sewing device 110, turning device 100, and hem-sewing device 120 are arranged sequentially. After the edge sewing is completed, the sewn product is conveyed to the turning device 100 for turning. After turning, the sewn product is directly fitted onto the fixing mechanism 20 of the hem-sewing device 120 for hem sewing. This achieves an automatic turning and fitting process, eliminating the need for manual operation, improving the automation level of the production line, and thus increasing production efficiency.

[0112] Please see Figure 10 This invention provides a method for turning over a sewn garment. The sewn garment includes a first fabric layer and a second fabric layer stacked together. The edges of the first fabric layer and the edges of the second fabric layer are connected. A first opening is formed at a first end of the sewn garment along a first direction. The turning over method includes:

[0113] Step S101: Control the opening mechanism 10 to drive at least one of a portion of the first fabric layer and a portion of the second fabric layer to move away from each other, thereby enlarging the first opening;

[0114] Step S103: Control the flipping mechanism 12 to extend into the sewn product from the first opening, contact the second end of the sewn product along the first direction, and drive the second end of the sewn product to pass through the first opening, so that the sewn product is flipped.

[0115] Step S105: After the sewn product is turned over, the opening mechanism 10 drives the first end to contact the fitting mechanism 14.

[0116] Step S107: After the control fitting mechanism 14 contacts the first end, it drives the sewn product to move toward the processing mechanism of the next process through the first end so that the first opening is fitted onto the processing mechanism.

[0117] The above-mentioned sewing production line 200 and the method for turning over sewn products involve the opening mechanism 10 fixing the first fabric layer and the second fabric layer respectively, making the first opening larger, the turning mechanism 12 driving the second end to pass through the first opening to achieve turning over, and finally the fitting mechanism 14 fitting the turned sewn product onto the processing mechanism of the next process, completely replacing manual operation and improving production efficiency.

[0118] Specifically, after the sewn product completes the previous process, it is transported to the flipping device 100. When the sewn product is transferred to the support plate 30, the first direction drive member 31a and the second direction drive member 31b drive the cloth plate assembly to move above the sewn product and press it against the sewn product. Then, the air blowing pipe 31d provides air along the first direction to flatten the sewn product, remove the wrinkles on the sewn product, and make the first end of the sewn product flat on the support plate 30.

[0119] The first lifting assembly 24, via the second bracket 22, drives the clamping assembly 26 to descend along the second direction, moving it until the needle suction cup 27 contacts the first fabric layer of the sewn product. The needle suction cup 27 controls the needle to extend and pierce the first fabric layer. The first lifting assembly 24 then drives the clamping assembly 26 to rise along the second direction, and the needle suction cup 27 drives the first fabric layer to rise until it stops after reaching a certain distance. At this point, the first gripper assembly 28 is activated to fix the first fabric layer.

[0120] After the clamping mechanism 18 moves the first fabric layer upward, making the first opening larger, the fixing mechanism 20 fixes the second fabric layer through the second gripper assembly 32. Thus, the clamping mechanism 18 fixes the first fabric layer, the fixing mechanism 20 fixes the second fabric layer, and the first opening remains stably open.

[0121] After the first opening is opened, the flipping mechanism 12 extends into the inside of the sewn product through the first opening, contacts and drives the second end of the sewn product to move along the first direction, and passes out through the first opening, thereby flipping the inner side of the sewn product into the outer side.

[0122] After the flipping is completed, the fixing mechanism 20 moves the sewn product along the second direction to between the third gripper assembly 50 of the fitting mechanism 14 and the processing mechanism of the next process. The fitting mechanism 14 moves towards the processing mechanism along the first direction, so that the third gripper assembly 50 contacts the second fabric layer of the sewn product. At this time, the third gripper assembly 50 fixes the second fabric layer, and the fixing mechanism 20 moves downward. At this time, the sewn product is in a state where the second fabric layer at the first end is fixed to the third gripper assembly 50. The first fabric layer hangs down naturally, so that the first opening faces the processing mechanism of the next processing device.

[0123] After acquiring the sewn product, the fitting mechanism 14 waits at a preset waiting position for the hem sewing device 120 to issue a fitting command before starting to move the sewn product down to the hem sewing device 120. After acquiring the sewn product, the fitting mechanism 14 pauses at the waiting position to confirm whether it is currently possible to fit the sewn product down to the hem sewing device 120.

[0124] An inspection position is set between the fitting mechanism 14 and the hem sewing device 120. The fitting mechanism 14 moves the sewn product toward the hem sewing device 120 along a first direction. Before fitting the sewn product onto the hem sewing device 120, the fitting mechanism 14 stops at the inspection position, and the sweeping assembly 60 moves along the cover plate 62 to sweep off any portion of the sewn product that may still be draped over the cover plate 62, allowing the second end of the sewn product to hang down naturally. After sweeping off any portion of the sewn product that may still be draped over the cover plate 62 at the inspection position, the fitting mechanism 14 is then controlled to fit the first end onto the hem sewing device 120. This prevents interference at the second end of the sewn product when the fitting mechanism 14 fits the first end onto the processing mechanism.

[0125] Finally, the third drive assembly drives the third gripper assembly 50 to move along the first direction, thereby causing the first opening to be fitted onto the machining mechanism.

[0126] In some implementations, the flipping method includes:

[0127] Initialize the control opening mechanism 10, the flipping mechanism 12, and the assembly mechanism 14.

[0128] In this way, by setting the initial positions of the opening mechanism 10, the flipping mechanism 12, and the mounting mechanism 14, and resetting the opening mechanism 10, the flipping mechanism 12, and the mounting mechanism 14 before controlling the flipping device 100 to work, it can be ensured that each component moves accurately in each operation, thereby successfully completing the flipping operation.

[0129] Specifically, after the air is turned on and the power is supplied, the control opening mechanism 10, the flipping mechanism 12 and the fitting mechanism 14 are initialized respectively.

[0130] The gripping mechanism 18 of the opening mechanism 10 controls the needle tip of the needle suction cup 27 to retract and controls the gripping assembly 26 to move upward to trigger the photoelectric switch used for positioning the gripping mechanism 18. The opening of the second gripper assembly 32 faces the positive direction of the second direction and moves to the middle position of the guide rail.

[0131] The fixing mechanism 20 of the opening mechanism 10 moves downward to contact the light-emitting switch used to position the fixing mechanism 20, as the initial position.

[0132] The telescopic bracket 42 of the flipping mechanism 12 retracts into the fixed bracket 40. The mop assembly 31 moves to one side of the support plate 30. The sweeping assembly 60 moves to the side closer to the edge sewing device 110.

[0133] The fitting mechanism 14 moves downward toward the sewing device until it triggers a photoelectric switch for positioning the fitting mechanism 14, then moves a preset distance in the opposite direction as its initial position. The preset distance is set according to the specific dimensions and layout of the turning device 100. It should be noted that the above explanation of the implementation method and beneficial effects of the turning device 100 also applies to the sewing production line 200 and the turning method of the sewn product in the embodiments of this application. To avoid redundancy, it will not be elaborated in detail here.
