Description

Technical Field

[0001] The present application relates to the technical field of garment processing, and more specifically, to a garment hemming processing technology and processing equipment. Background Art

[0002] A hem stitch refers to folding and sewing the edge parts of a garment, such as the front placket, bottom edge, cuffs, trouser cuffs, etc. A triple hem stitch means first folding a narrow edge inward on the edge of the garment, then continuing to fold a wide edge inward, and then sewing along the inner edge adjacent to the wide edge, so that the folded upper wide edge and middle narrow edge are sewn onto the base fabric together.

[0003] When sewing a triple hem, especially when sewing a wide hem with a width greater than 6 cm, the hemming is generally done manually. For example, first press a small overlapping section of the narrow edge and the wide edge by hand to sew a small section, and then continue to press a small overlapping section of the narrow edge and the wide edge by hand to sew a small section until the entire hem is sewn. The efficiency of this sewing method is low, and manual hemming is also prone to uneven hem width. Currently, there are also some triple hem stitch technologies that use a ruler to measure and adjust the width of each small section of the folded hem, but the efficiency of this sewing method is low. Summary of the Invention

[0004] In order to improve the problems of uneven hem width and low efficiency in garment hemming sewing, the present application proposes a garment hemming processing technology and processing equipment to improve the uneven hem width phenomenon in garment hemming sewing and improve the hemming sewing efficiency.

[0005] In a first aspect, the present application proposes a garment hemming processing equipment and adopts the following technical solutions.

[0006] A garment hemming processing equipment, the garment hemming processing equipment includes a processing platform, a cover plate, a bottom plate, two suction cup manipulators and a pressing component.

[0007] The processing platform includes an adjacent folding area and a transmission area; the two suction cup manipulators are arranged on both sides of the folding area and are configured to be able to adsorb the cover plate and cover the cover plate on the bottom plate in the folding area.

[0008] Both ends of the cover plate and both ends of the bottom plate are mutually misaligned; each suction cup manipulator is provided with at least two suction cups to adsorb the cover plate and the bottom plate on the same side, so that the two suction cup manipulators can simultaneously adsorb both ends of the cover plate and both ends of the bottom plate; the adsorbed cover plate and bottom plate are closely attached to each other to form a clamping component.

[0009] The two suction cup type manipulators are further configured to be able to rotate the clamping assembly around the side close to the transfer area as the rotation axis multiple times until it lies flat on the processing platform, and the clamping assembly after multiple rotations reaches the transfer area.

[0010] The suction cup type manipulator is further configured to be able to adsorb the cover plate and the bottom plate and translate them out of the transfer area in a direction parallel to any one of the rotation axes.

[0011] The pressing component is arranged above the transfer area and is configured to be able to press down on the clamping assembly rotated to the transfer area and to press down on the surface of the processing platform after the clamping assembly is translated out of the transfer area.

[0012] By adopting the above technical solutions, the processing equipment can automatically hem garments and can produce in batches, with uniform hem widths and high efficiency. First, place the bottom plate on the folding area of the processing platform. According to the hem requirements, a narrow hem can be folded first for the garment (or fabric), including placing the edge of the garment (or fabric) to be processed that needs to be hemmed on the bottom plate. The two suction cup type manipulators adsorb the cover plate and cover the cover plate on the fabric on the bottom plate. Then the two suction cup type manipulators simultaneously adsorb the cover plate and the bottom plate to form a clamping assembly for clamping the fabric. With the side of the clamping assembly adjacent to the transfer area as the rotation axis, the clamping assembly is flipped to form a primary hem (usually a narrow hem) for the fabric. Then, with the side of the clamping assembly adjacent to the transfer area as the rotation axis again, the clamping assembly is flipped to form a secondary hem (usually a wide hem) for the fabric. Generally, the flipping action is completed at this time, or the clamping assembly can be flipped one to several more times according to requirements. After the flipping action is completed, the pressing component presses down on the clamping assembly, and the suction cup type manipulator adsorbs the cover plate and the bottom plate and translates them out of the transfer area in a direction parallel to any one of the rotation axes, leaving the folded fabric. The pressing component continues to press down so that the fabric is flattened and a shaped hem mark is generated on the fabric. The above process is basically automatic and can be replicated and produced in batches. The clamping mechanism of the cover plate and the bottom plate makes the hem width of the garment uniform. The automatic drive setting of the suction cup type manipulator improves the hem efficiency, and the stable hem can also improve the efficiency of the next sewing step.

[0013] As an improvement to the garment hemming processing equipment, the suction cup type manipulator has a rotating head that can rotate 360°, and two suction cups with the same orientation are installed on the rotating head.

[0014] By adopting the above technical solutions, the two suction cups with the same orientation on each suction cup type manipulator can simultaneously adsorb one side of the cover plate and one side of the bottom plate. The two suction cup type manipulators cooperate to simultaneously adsorb both sides of the cover plate and both sides of the bottom plate to perform clamping and continuous 180° flipping or horizontal movement and other actions, and can complete the process actions required for garment hemming.

[0015] As an improvement to the hemming processing equipment for the clothing, when the clamping assembly is driven by the suction cup manipulator and is placed with the bottom plate facing upward in the folding area, the rotating head is located at the lower surface of the clamping assembly, and the processing platform gives way to the rotating head here.

[0016] By adopting the above technical solution, the suction cup manipulator with a rotatable 360° rotating head will not interfere with the processing platform, operates smoothly, and when the clamping assembly moves to the transfer area, the suction cup manipulator is completely above the processing platform and will not interfere with the processing platform, facilitating processing.

[0017] As an improvement to the hemming processing equipment for the clothing, the length of the bottom plate is greater than the length of the cover plate, or the two ends of the bottom plate and the two ends of the cover plate are provided with protruding and mutually misaligned ears, so that after the cover plate covers the bottom plate, both ends can be mutually misaligned.

[0018] By adopting the above technical solution, if the length of the bottom plate is greater than the length of the cover plate, the cover plate can be covered on the bottom plate in a way that both ends are retracted inside the bottom plate, so that the cover plate and the bottom plate are misaligned at both ends, facilitating the suction cup manipulator to adsorb the cover plate and the bottom plate simultaneously. If the two ends of the bottom plate and the two ends of the cover plate are provided with protruding and mutually misaligned ears, the cover plate can be covered on the bottom plate so that the two ends of the bottom plate and the cover plate are also mutually misaligned, facilitating the suction cup manipulator to adsorb the cover plate and the bottom plate simultaneously.

[0019] As an improvement to the hemming processing equipment for the clothing, the friction coefficient of the surface of the transfer area of the processing platform is 0.5 - 1.5; the bottom surface friction coefficient of the pressing component is 0.5 - 1.5; the double-sided friction coefficient of the cover plate < 0.2; the double-sided friction coefficient of the bottom plate < 0.2.

[0020] By adopting the above technical solution, both the transfer area of the processing platform and the pressing component have a large friction force with the clothing (or fabric), while the friction force between the clothing and the cover plate and the bottom plate is small. When pressing the pressing component on the combination of the folded clothing and the clamping assembly, using the suction cup manipulator to adsorb the cover plate and the bottom plate, the cover plate and the bottom plate can be smoothly pulled out, and the clothing can remain in the form of folding between the transfer area of the processing platform and the pressing component, increasing the pressure of the pressing component to press the clothing into shape, and the formed hemming width is uniform.

[0021] As an improvement to the garment hemming processing equipment, the garment hemming processing equipment further includes a transportation component, a feeding propulsion component, a sewing component, and a discharging propulsion component; the transportation component is arranged at the bottom of the transmission area and can receive and convey the clamping component entering the transmission area; the feeding propulsion component, the sewing component, and the discharging propulsion component are installed above the processing platform; the feeding propulsion component is arranged at the output end of the transportation component; the sewing component is arranged at the output end of the feeding propulsion component; the discharging propulsion component is arranged at the output end of the sewing component.

[0022] By adopting the above technical solution, the transportation component at the bottom of the transmission area will not interfere with the pressing component, and can move the fabric from the transmission area to the feeding propulsion component. The feeding propulsion component above the processing platform can press the fabric on the processing platform and push the fabric into the sewing component for sewing. It has strong driving force, stable propulsion, straight sewing thread and uniform stitch spacing. The discharging propulsion component at the rear can further pull out the fabric, further improving the straightness of the sewing thread and the uniformity of the stitch spacing, and also facilitating the discharging of the fabric and reducing the accumulation of the fabric.

[0023] As an improvement to the garment hemming processing equipment, the transportation component includes a plurality of parallel conveyor belts and a first rotary drive; the processing platform is provided with a plurality of penetrating strip-shaped holes at the transmission area, and the upper surfaces of the plurality of parallel conveyor belts are embedded in the plurality of strip-shaped holes; the first rotary drive is installed below the processing platform and is connected in series with the plurality of conveyor belts through the same output shaft, and can drive the plurality of conveyor belts to operate simultaneously.

[0024] By adopting the above technical solution, the plurality of conveyor belts rotate synchronously, and synchronously rely on the frictional force to act on multiple parts of the fabric, so that each part of the fabric can move forward synchronously, and the fabric has a good shape retention effect and is not easily deformed.

[0025] As an improvement to the garment hemming processing equipment, the feeding propulsion component includes a plurality of guiding wheels and a second rotary drive; the second rotary drive is connected in series with the plurality of guiding wheels through the same output shaft; two of the guiding wheels are respectively arranged on the extension lines of the two sides of the clamping component reaching the transmission area. The discharging propulsion component includes a plurality of discharging wheels and a third rotary drive; the third rotary drive is connected in series with the plurality of discharging wheels through the same output shaft; two of the discharging wheels are respectively arranged on the extension lines of the two sides of the clamping component reaching the transmission area.

[0026] By adopting the above technical solution, the two folded edges of the imported wheel pair fabric are pressed and pushed, flattening the folded edges further to facilitate sewing. The fabric is pressed and pushed by multiple imported wheels, with uniform force applied to each part of the fabric. Compared with the method of pressing and pushing the fabric with a single roller, the phenomenon of fabric wrinkles during the process of pushing the fabric is reduced. Multiple export wheels cooperate with multiple import wheels to stably push the fabric forward for sewing, reducing the phenomenon of fabric wrinkles during the process of pushing the fabric, and also making the sewing thread straight and the stitch distance uniform. The two side edges of the clamping assembly are the rotating shafts of the clamping assembly.

[0027] In a second aspect, the present application also proposes a clothing hem processing technology and adopts the following technical solutions.

[0028] A clothing hem processing technology uses the above-mentioned clothing hem processing equipment to process the clothing hem. The clothing hem processing technology includes:

[0029] Place the bottom plate on the folding area;

[0030] Lay the fabric on the transmission area and the folding area, and make the edge to be folded of the fabric located on the bottom plate;

[0031] Two of the suction cup manipulators adsorb the cover plate and cover the cover plate on the bottom plate;

[0032] Two of the suction cup manipulators simultaneously adsorb the cover plate and the bottom plate, so that the cover plate and the bottom plate form the clamping assembly, and the clamping assembly clamps the fabric; each time, taking the side of the clamping assembly close to the transmission area as the rotation axis, the two suction cup manipulators drive the clamping assembly to rotate multiple times, so that the clamping assembly lies flat on the transmission area, and the fabric is wound around the clamping assembly;

[0033] The pressing component presses down on the clamping assembly that clamps the fabric, and the suction cup manipulator is horizontally withdrawn in a direction parallel to any one of the rotation axes to remove the cover plate and the bottom plate from the transmission area;

[0034] The pressing component continues to press down to flatten the fabric and produce a hem crease on the fabric.

[0035] By adopting the above technical solution, driven by the two suction cup manipulators, the bottom plate and the cover plate jointly clamp the edge of the fabric. After the initial flipping of the clamping assembly composed of the cover plate and the bottom plate, the fabric forms an unshaped primary hem. Continuing to flip the clamping assembly, the fabric forms an unshaped secondary hem while maintaining the primary hem. At this time, the flipping can be ended, or the clamping assembly can be selected to continue flipping. After the cover plate and the bottom plate are withdrawn, the pressing assembly presses the fabric with the unshaped primary hem and the unshaped secondary hem, so that the fabric forms a shaped primary hem and a secondary hem, that is, the above-mentioned method of making the fabric have a hem mark for the next sewing step. Compared with manual hemming, the automatic hemming method adopted in this way has high efficiency and uniform hemming.

[0036] In a third aspect, the present application also proposes a garment hemming processing technology including a sewing step, and adopts the following technical solution.

[0037] A garment hemming processing technology uses the above-mentioned garment hemming processing equipment for garment hemming processing. The garment hemming processing technology includes:

[0038] According to the width and folding layer requirements of the garment hem, use two of the suction cup manipulators to clamp and flip the cover plate and the bottom plate on the fabric;

[0039] Use two of the suction cup manipulators to withdraw the cover plate and the bottom plate from the fabric while maintaining the flipped shape of the fabric;

[0040] Use the pressing assembly to press the fabric with the maintained flipped shape and make the fabric have a hem mark at the flipping place;

[0041] Start the transportation assembly to transport the fabric with the hem mark to the feeding and pushing assembly;

[0042] The feeding and pushing assembly evenly pushes the fabric into the sewing assembly;

[0043] The sewing assembly sews the fabric;

[0044] The feeding and pushing assembly continuously and evenly advances the fabric during the sewing process of the fabric;

[0045] Set the advancing speeds of the discharging and pushing assembly and the feeding and pushing assembly to be the same, and the discharging and pushing assembly evenly pulls out the sewn fabric to complete the sewing of the fabric.

[0046] By adopting the above technical solution, the fabric has regular hem marks, is evenly fed into the sewing assembly for sewing, the sewn stitches are straight and the stitch distance is uniform, and the production efficiency is high.

[0047] In summary, the clothing hemming processing equipment and the clothing hemming processing technology of the present application have the following beneficial effects:

[0048] Driven by the two suction cup manipulators, the bottom plate and the cover plate jointly clamp the edge of the fabric. After the initial flipping of the clamping assembly composed of the cover plate and the bottom plate, the fabric forms a primary hem that is clamped but not shaped. When the clamping assembly is flipped, the fabric forms an unshaped secondary hem while maintaining the primary hem. At this time, the flipping can be ended, or the clamping assembly can be selected to continue flipping. After the cover plate and the bottom plate are withdrawn, the pressing assembly presses the fabric with the unshaped primary hem and the unshaped secondary hem, so that the fabric forms a shaped primary hem and a secondary hem, that is, the above-mentioned method of making the fabric produce a hem mark, which is convenient for the next sewing step. Using this automatic hemming method, compared with manual hemming, the efficiency is high and the hemming is uniform. The hemmed fabric is fed into the sewing assembly at a constant speed for sewing. The sewn stitches are straight and the stitch spacing is uniform, and the production efficiency is high. Description of the Drawings

Detailed implementation manners

[0058] Some implementation manners of the garment hemming processing equipment and processing technology of the present application will be specifically described below with reference to the accompanying drawings.

[0059] Embodiment 1

[0060] Please refer to Figure 1 , a garment hemming processing equipment, the garment hemming processing equipment includes a processing platform 1, a cover plate 2, a bottom plate 3, two suction cup manipulators 4 and a pressing component 5. Through these components, the garment or fabric can be automatically hemmed and can be well shaped. The specific structure of the equipment is as follows.

[0061] Please refer to Figure 2 , the processing platform 1 includes an adjacent folding area 101 and a transmission area 102. Taking the direction from the folding area 101 to the transmission area 102 as the horizontal transverse direction, a accommodating groove 1011 can be opened at a horizontal transverse end of the folding area 101 far from the transmission area 102. The horizontal longitudinal ends of the accommodating groove 1011 are open, and the accommodating groove 1011 is used to place the bottom plate 3. The two ends of the bottom plate 3 can extend out of the folding area 101, or one end or both ends may not extend out of the folding area 101.

[0062] The garment hemming processing equipment may further include a storage rack 7 for placing the cover plate 2. The storage rack 7 is arranged outside the folding area 101 and at the end far from the transmission area 102.

[0063] Two suction cup manipulators 4 are arranged on the longitudinal sides of the folding area 101 and are configured to be able to adsorb the cover plate 2 and cover the cover plate 2 on the bottom plate 3 in the folding area 101.

[0064] The transverse sides of the cover plate 2 are parallel edges, and the transverse sides of the bottom plate 3 are also parallel edges, which abut against the fabric 6 to form parallel folded edges. The longitudinal ends of the cover plate 2 and the longitudinal ends of the bottom plate 3 are all offset from each other. It can be that both the cover plate 2 and the bottom plate 3 are rectangular, and the length of the bottom plate 3 is greater than the length of the cover plate 2. Then the cover plate 2 can be covered on the bottom plate 3 in a way that both ends are retracted inside the bottom plate 3, so that the two ends of the cover plate 2 and the bottom plate 3 are offset from each other, facilitating the suction cup manipulator 4 to adsorb the cover plate 2 and the bottom plate 3 simultaneously. It can also be that the main bodies of the cover plate 2 and the bottom plate 3 are both rectangular, and there are ears 21 protruding from the rectangles at both ends of the bottom plate 3 and both ends of the cover plate 2. The ears 21 at both ends of the bottom plate 3 and the ears 21 at both ends of the cover plate 2 are offset from each other. When the cover plate 2 is covered on the bottom plate 3, the two ends of the bottom plate 3 and the cover plate 2 can be offset from each other, facilitating the suction cup manipulator 4 to adsorb the cover plate 2 and the bottom plate 3 simultaneously.

[0065] Please refer to Figure 3 , in order to adsorb the cover plate 2 and the bottom plate 3 simultaneously, each suction cup manipulator 4 is provided with at least two suction cups 401 to adsorb one end of the cover plate 2 and one end of the bottom plate 3 on the same side. The two suction cup manipulators 4 cooperate to adsorb both ends of the cover plate 2 and both ends of the bottom plate 3 simultaneously. The adsorbed cover plate 2 and bottom plate 3 are closely attached to form a clamping assembly 23, which can clamp the fabric 6 to complete the edge folding action.

[0066] Please refer to Figure 4 , the two suction cup manipulators 4 can rotate the clamping assembly 23 multiple times with the side close to the transfer area 102 as the rotation axis 231 each time and place it flat on the processing platform 1. After multiple rotations, the clamping assembly 23 rotates to the transfer area 102. In this embodiment, taking triple edge folding as an example, the fabric 6 is rotated twice.

[0067] Please refer to Figure 5 , the first rotation causes the fabric 6 to generate a narrow folded edge 601, which serves as the edge wrapping of the fabric 6. The second rotation causes the fabric 6 to generate a wide folded edge 602, and the width of this wide folded edge 602 is the edge folding width of the fabric 6. According to the edge folding requirements, the width of the edge wrapping (the initial narrow folded edge 601) can be 0.5 - 1.5 cm, and the width of the edge folding (the secondary wide folded edge 602) can vary from 1 to 15 cm. The width of the wide folded edge 602 is greater than the width of the narrow edge wrapping, so as to fold the edge parts of the clothing, such as the front placket, bottom edge, cuffs, trouser cuffs, etc., and then sew and fix them. The transverse widths of the cover plate 2 and the bottom plate 3 can both be equal to the width of the secondary edge folding.

[0068] After the clamping assembly 23 is flipped twice, the clamping assembly 23 reaches the transfer area 102. At this time, the cover plate 2 and the bottom plate 3 still need to be pulled away from the fabric 6. After being pulled away, the folded edges on both sides of the fabric 6 are still in an arc shape 604 and have not been shaped into folded edges. Therefore, pressing is still required to press the folded edges on both sides of the fabric 6 into shape, so that straight creases are formed on both sides of the flipped part of the fabric 6, and the folded edges of the fabric 6 are shaped to perform the next step of sewing. Using this method, it is not necessary to continuously press the fabric 6 by hand to form folded edges and perform sewing.

[0069] For the above, when the cover plate 2 and the bottom plate 3 are pulled away from the fabric 6, a suction cup manipulator 4 outside the processing platform 1 is used to adsorb the cover plate 2 and the bottom plate 3, and the cover plate 2 and the bottom plate 3 are translated out of the fabric 6 in a direction parallel to any rotation axis 231.

[0070] After the cover plate 2 and the bottom plate 3 are translated out of the fabric 6, the fabric 6 still needs to be pressed. Pressing the fabric 6 can be performed by the pressing assembly 5. By setting a hanging bracket 8 outside the processing platform 1, the pressing assembly 5 is installed on the hanging bracket 8. The pressing assembly 5 is arranged above the transfer area 102 and can press down on the clamping assembly 23 rotated to the transfer area 102.

[0071] Please refer to Figure 6 , optionally, the pressing assembly 5 includes a vertical electric telescopic rod 501, and a horizontal pressing plate 502 is arranged at the bottom of the electric telescopic rod 501. The horizontal pressing plate 502 can completely cover the folded part of the fabric 6 and can also press the fabric 6 from which the cover plate 2 and the bottom plate 3 are pulled away to form a shaped folded edge.

[0072] As Figure 5 shown in step A to step B to step C to step D of

[0073] First, place the bottom plate 3 on the folding area 101 of the processing platform 1. According to the folding edge requirements, first fold a narrow hem for the garment (or fabric 6), including placing the edge of the garment (or fabric 6) to be processed that needs to be hemmed on the bottom plate 3. The width of the narrow hem is related to the placement position of the fabric 6 and the alignment amount of the cover plate 2 and the bottom plate 3. Specifically, it is determined by the distance between the cover plate 2 and the edge of the fabric 6. When the side of the cover plate 2 and the bottom plate 3 adjacent to the transfer area 102 are aligned, the width of the fabric 6 placed on the bottom plate 3 is the required hemming amount (hem width). Alignment lines 301 can be set on the bottom plate 3, and the edge of the fabric 6 is aligned with this line to fold the edge.

[0074] Next, two suction cup manipulators 4 adsorb the cover plate 2 and cover the cover plate 2 on the bottom plate 3, covering a part of the fabric 6 on the bottom plate 3 together. The two suction cup manipulators 4 then simultaneously adsorb the cover plate 2 and the bottom plate 3, and the cover plate 2 and the bottom plate 3 form a clamping assembly 23 for clamping the fabric 6. Taking the side of the clamping assembly 23 adjacent to the transmission area 102 as the rotation axis 231, the clamping assembly 23 is flipped so that the fabric 6 forms a primary hem (usually a narrow hem), and then taking the side of the clamping assembly 23 adjacent to the transmission area 102 as the rotation axis 231 again, the clamping assembly 23 is flipped so that the fabric 6 forms a secondary hem (usually a wide hem 602). Generally, the flipping action is completed at this time, or the clamping assembly 23 can be flipped one to several times again according to requirements. After the flipping action is completed, the pressing assembly 5 presses down on the clamping assembly 23, and the suction cup manipulators 4 adsorb the cover plate 2 and the bottom plate 3 and translate out of the transmission area 102 in a direction parallel to any rotation axis 231, leaving the folded but not yet shaped fabric 6. The pressing assembly 5 increases the pressure and continues to press down so that the fabric 6 is flattened, and the fabric 6 generates a shaped hem mark 603. The above process is basically automatic and can be mass-produced. The clamping mechanism of the cover plate 2 and the bottom plate 3 makes the hem width of the clothing uniform. The automatic drive setting of the suction cup manipulators 4 improves the hem efficiency, and the stable hem can also improve the efficiency of the next sewing step.

[0075] Using the above hemming method, the hem width of the processed fabric 6 is uniform and the production efficiency is high.

[0076] Among them, the width of the bottom plate 3 can be equal to or different from the width of the cover plate 2. One of the optional methods is that the width of the cover plate 2 is equal to the width of the bottom plate 3, and the width between the receiving groove 1011 of the folding area 101 and the transmission area 102 is set to be ≤ the width of the cover plate 2. The cover plate 2 and the bottom plate 3 are butted flush in the width direction to clamp the fabric 6, so that the clamping assembly 23 reaches the transmission area 102 after two flips.

[0077] In order to facilitate adsorption, flipping and avoid interference with the processing platform 1 during the flipping process, the suction cup manipulator 4 is provided with a rotating head 402 that can rotate 360°. Two suction cups 401 with the same orientation are installed on the rotating head 402. The suction cup 401 can be a vacuum pumping suction cup 401 or an electromagnetic suction cup 401.

[0078] The two suction cups 401 with the same orientation of each suction cup manipulator 4 can simultaneously adsorb one side of the cover plate 2 and one side of the bottom plate 3. The two suction cup manipulators 4 cooperate to simultaneously adsorb both sides of the cover plate 2 and both sides of the bottom plate 3 to perform clamping and continuous 180° flipping and other actions, and can also extract the cover plate 2 and the bottom plate 3 from the folded fabric 6, and can complete the process actions required for clothing hemming.

[0079] During the flipping process, when the clamping assembly 23 is driven by the suction cup manipulator 4 and the bottom plate 3 is flat against the folding area 101 with the bottom surface facing up, the suction cup manipulator 4 is located at the lower surface of the clamping assembly 23, and the processing platform 1 gives way to the suction cup manipulator 4. For example, the longitudinal length of the folding area 101 is less than the length of the bottom plate 3 or the cover plate 2, so that the rotating head 402 for adsorbing the bottom plate 3 and the cover plate 2 is outside the folding area 101.

[0080] With the above settings, the suction cup manipulator 4 with a rotatable head 402 that can rotate 360° will not interfere with the processing platform 1, and can operate smoothly. When the clamping assembly 23 moves to the transfer area 102, the suction cup manipulator 4 is completely above the processing platform 1 and will not interfere with the processing platform 1, which is convenient for processing.

[0081] In order to smoothly remove the cover plate 2 and the bottom plate 3 from the fabric 6 after the fabric 6 is folded twice, a smooth cover plate 2 and bottom plate 3 can be provided, and at the same time, a relatively rough bottom surface of the pressing component 5 and a relatively rough surface of the transfer area 102 of the processing platform 1 are provided. For example, the friction coefficient of the transfer area 102 surface of the processing platform 1 is set to be 0.5 - 1.5, the friction coefficient of the bottom surface of the pressing component 5 is 0.5 - 1.5, the double-sided friction coefficient of the cover plate 2 < 0.2, and the double-sided friction coefficient of the bottom plate 3 < 0.2. Through this setting, the friction between the transfer area 102 of the processing platform 1 and the garment (or fabric 6) is large, and at the same time, the friction between the pressing component 5 and the garment (or fabric 6) is large, while the friction between the garment and the cover plate 2 and the bottom plate 3 is small. Therefore, when the pressing component 5 is pressed on the combination of the folded fabric 6 and the clamping assembly 23, by using the suction cup manipulator 4 to adsorb the cover plate 2 and the bottom plate 3 successively, the cover plate 2 and the bottom plate 3 can be smoothly removed from the garment successively, and the fabric 6 can remain in the folded original shape between the transfer area 102 of the processing platform 1 and the pressing component 5, so that the garment can be further pressed and formed, and the width of the formed hem is uniform.

[0082] Embodiment 2

[0083] Please refer to Figure 1 , on the basis that the garment hemming processing equipment in Embodiment 1 includes a processing platform 1, a cover plate 2, a bottom plate 3, two suction cup manipulators 4 and a pressing component 5, please refer to Figure 7 and Figure 8 , the garment hemming processing equipment of this embodiment further includes a transportation component 9, a feeding propulsion component 11, a sewing component 12 and a discharging propulsion component 13.

[0084] The transportation component 9 is arranged at the bottom of the transfer area 102 and can receive and convey the clamping assembly 23 entering the transfer area 102. The transportation component 9 at the bottom of the transfer area 102 will not interfere with the pressing component 5 and can move the fabric 6 from the transfer area 102 to the feeding propulsion component 11.

[0085] The feeding propulsion assembly 11, the sewing assembly 12 and the discharging propulsion assembly 13 are installed above the processing platform 1. The feeding propulsion assembly 11 is arranged at the output end of the conveying assembly 9. The sewing assembly 12 is arranged at the output end of the feeding propulsion assembly 11. The discharging propulsion assembly 13 is arranged at the output end of the sewing assembly 12.

[0086] The feeding propulsion assembly 11 above the processing platform 1 can press the received hemmed fabric 6 onto the processing platform 1 and automatically push the fabric 6 into the sewing assembly 12 for sewing. This mechanical propulsion method makes the advancing direction of the fabric 6 straight and the speed uniform, so that the sewing thread is straight and the stitch spacing is uniform. The rear discharging propulsion assembly 13 can further pull out the sewn fabric 6 at a uniform speed and in the same stable direction, further improving the straightness of the sewing thread and the uniformity of the stitch spacing, and also facilitating the feeding of the fabric 6 and reducing the accumulation of the fabric 6. The position of the sewing thread can be 0.1 - 0.3 mm inward from the outer edge of the hem.

[0087] Optionally, the conveying assembly 9 may include multiple parallel conveyor belts 901 and a first rotary driver 902, for example, three parallel conveyor belts. The first rotary driver 902 may be a motor. The processing platform 1 is provided with three penetrating strip-shaped holes at the conveying area 102, and the upper surfaces of the three parallel conveyor belts 901 are embedded in the three strip-shaped holes. The first rotary driver 902 is installed below the processing platform 1 and drives the three conveyor belts 901 to rotate synchronously through the same output shaft. One conveyor belt 901 is located below one hem of the fabric 6, the second conveyor belt 901 is located below the other hem of the fabric 6, and the third conveyor belt 901 is located below the fabric 6 in the area where no hemming is performed. This setting can stably convey the fabric 6 and is not likely to cause wrinkles on the fabric 6. During the conveying process, the multiple conveyor belts 901 rotate synchronously and rely on friction to act on multiple parts of the fabric 6, so that each part of the fabric 6 can move forward synchronously, and the fabric 6 has a good shape retention effect and is not easily deformed.

[0088] Optionally, the feeding propulsion assembly 11 includes multiple guiding wheels 1101 and a second rotary driver 1102, for example, three guiding wheels 1101. The guiding wheels 1101 can be cylindrical, with the same cross-sectional diameter, increasing the contact area with the fabric 6 and reducing the probability of wrinkles on the fabric 6 during the transportation process. The second rotary driver 1102 may be a motor. The second rotary driver 1102 is connected in series with multiple guiding wheels 1101 through the same output shaft. Two of the guiding wheels 1101 are respectively arranged on the extension lines of the two hems of the fabric 6 on the clamping assembly 23 reaching the conveying area 102, so that the guiding wheels 1101 can press the two sides of the hem to facilitate sewing the inner hem.

[0089] The sewing assembly 12 may include an automatic needle 1201 and a presser foot 1202 having an arcuate 604 inlet.

[0090] Optionally, the structure of the discharge propulsion assembly 13 may be the same as that of the feeding propulsion assembly 11. For example, the discharge propulsion assembly 13 includes three discharge wheels 1301 and a third rotary driver 1302, and the third rotary driver 1302 may be a motor. The third rotary driver 1302 serially connects the three discharge wheels 1301 through the same output shaft. Two of the discharge wheels 1301 are respectively disposed on the extended lines of the two folded edges of the fabric 6 on the clamping assembly 23 reaching the transmission area 102.

[0091] In this processing equipment, the guiding wheels 1101 press and push the two folded edges of the fabric 6, further flattening the folded edges to facilitate sewing. By dividing the guiding wheels 1101 to press and push the fabric 6, the force applied to each part of the fabric 6 is uniform. Compared with the method of using a single roller to press and push the fabric 6, the phenomenon of wrinkles in the fabric 6 during the process of pushing the fabric 6 is reduced. The multiple discharge wheels 1301 cooperate with the multiple guiding wheels 1101 to stably advance the fabric 6 for sewing, reducing the phenomenon of wrinkles in the fabric 6 during the process of pushing the fabric 6, and also making the sewing thread straight and the stitch distance uniform.

[0092] The above-mentioned clothing hem processing equipment can be used for clothing hem processing, and the clothing hem processing process includes:

[0093] Place the bottom plate 3 on the folding area 101;

[0094] Lay the fabric 6 on the transmission area 102 and the folding area 101, and make the edge to be folded of the fabric 6 located on the bottom plate 3;

[0095] Two suction cup manipulators 4 adsorb the cover plate 2 and cover the cover plate 2 on the bottom plate 3;

[0096] The two suction cup manipulators 4 simultaneously adsorb the cover plate 2 and the bottom plate 3, so that the cover plate 2 and the bottom plate 3 form a clamping assembly 23, and the clamping assembly 23 clamps the fabric 6; each time, taking the side of the clamping assembly 23 close to the transmission area 102 as the rotation axis 231, the two suction cup manipulators 4 drive the clamping assembly 23 to rotate twice, so that the clamping assembly 23 lies flat on the transmission area 102, and a part of the fabric 6 is wound around the clamping assembly 23;

[0097] The pressing assembly 5 presses down on the clamping assembly 23 clamping the fabric 6, and the suction cup manipulator 4 horizontally withdraws the cover plate 2 and the bottom plate 3 outside the processing platform 1 in a direction parallel to any rotation axis 231;

[0098] The pressing assembly 5 continues to press down, flattening the fabric 6 to form a formed hem mark 603 on the fabric 6;

[0099] Start the transport component 9 to transport the cloth 6 with the folding mark 603 to the feeding and pushing component 11;

[0100] The feeding and pushing assembly 11 pushes the cloth 6 into the sewing assembly 12 at a constant speed;

[0101] The sewing assembly 12 sews the cloth 6;

[0102] The feeding and pushing component 11 continuously pushes the cloth 6 at a uniform speed during the sewing process;

[0103] The material discharging pushing assembly 13 pulls out the sewn cloth 6 at a uniform speed at the same speed as the material feeding pushing assembly 11, so that the sewing of the cloth 6 is completed.

[0104] The cloth 6 has regular folding marks 603 and is fed into the sewing assembly 12 at a uniform speed for sewing. The sewn seams are straight and the seam distance is uniform, and the production efficiency is high.

[0105] In the above process, driven by two suction cup manipulators 4, the bottom plate 3 and the cover plate 2 jointly clamp the edge of the cloth 6. After the initial flipping of the clamping assembly 23 composed of the cover plate 2 and the bottom plate 3, the cloth 6 forms a clamped but unformed primary hemming. The clamping assembly 23 is flipped continuously, and the cloth 6 forms an unformed secondary folding edge while maintaining the primary hemming. At this time, the flipping is completed, and the clamping assembly 23 reaches the transmission area 102. The pressing assembly 5 is started, and a small downward pressure is set according to the roughness of the cloth 6, the roughness of the table surface, the roughness of the cover plate 2, the roughness of the bottom plate 3, etc., and pressed on the combination of the cloth 6 and the clamping assembly 23. Only one suction cup manipulator 4 outside the processing platform 1 is started to absorb the cover plate 2 and pull the cover plate 2 out horizontally to the outside of the processing platform 1. After the cover plate 2 is pulled out, the bottom plate 3 is pulled out in the same way. By increasing the pressure, the pressing component 5 presses down the fabric 6 with the unformed primary hem and the unformed secondary hem, so that the fabric 6 forms the formed primary hem and the secondary hem, that is, the hem mark 603 is generated on the fabric 6, and the next step of sewing is performed. Compared with manual hem folding, the automatic hem folding method using this method has high efficiency, uniform hem width, is not easy to produce wrinkles, and has uniform stitch length.

The material discharging inclined trough 14 is arranged at the output end of the material discharging pushing assembly 13, and the material frame 15 is arranged below the outlet of the material discharging inclined trough 14, and receives the garments after hemming and sewing. The processed garments can be automatically hemmed, automatically sewn and automatically unloaded in the garment hemming processing equipment, with high efficiency, low cost and high processing quality.
