Description

Technical Field

[0001] This invention relates to the field of garment packaging technology, and more particularly to an underwear folding and packaging machine. Background Technology

[0002] After the underwear is manufactured, in order to facilitate subsequent transportation, warehousing and market sales, the finished underwear usually needs to be folded and sorted, then packed into packaging bags and sealed to form standardized packaged finished products.

[0003] Currently, traditional underwear folding and packaging operations mostly rely on manual labor: operators manually fold the finished underwear, then put the folded underwear into packaging bags, and then transfer the packaging bags containing the underwear to the sealing station, where the packaging bag opening is sealed by heat-pressing equipment operated manually.

[0004] This purely manual operation mode has obvious shortcomings. Not only are labor costs high, but the overall process is also cumbersome and lacks continuity, resulting in low production efficiency for folding, bagging, and sealing underwear. It is difficult to adapt to the needs of large-scale and automated modern production, thus restricting the improvement of the overall automation level of the underwear production line.

[0005] Therefore, in order to overcome the shortcomings of traditional manual methods, it is necessary to provide an underwear folding and packaging machine that can automatically fold and bag underwear. Summary of the Invention

[0015] Preferably, the underwear folding packaging machine further includes a bag opening flattening module, which is disposed on the transverse support; the bag opening flattening module is driven by the vacuum transverse drive component to pass through the bag opening heat sealing space and the bag opening clamping space and insert into the packaging bag, so that the bag opening flattening module flattens the bag opening of the packaging bag.

[0016] Compared with existing technologies, the underwear folding and packaging machine of the present invention, by setting up a first conveying module, a folding module, a top-feeding module, a second conveying module, a packaging bag feeding module, a first suction bag-pulling module, a second suction bag-pulling module, a bag-supporting module, a bag-filling robot, a pressing module, and a sealing module, constructs a fully automated production line packaging system integrating underwear conveying, folding, lifting and handling, packaging bag feeding and conveying, bag pulling and supporting, automatic bag filling, pressing and shaping, sealing and storage. The first conveying module can stably convey... The system precisely divides the underwear into folding and handling stations, and works with the folding module to complete standardized underwear folding operations, eliminating problems such as inconsistent sizes, messy wrinkles, and inconsistent specifications caused by manual folding. Simultaneously, the top-loading module lifts the material, providing precise operating conditions for automated material handling and bagging. Meanwhile, the second conveying module, in conjunction with the packaging bag feeding module, realizes automated bag loading and station transfer. Relying on the first and second suction bag pulling modules, which perform bidirectional suction bag pulling in conjunction with the bag supporting module, it can precisely... The system accurately and stably opens the packaging bag opening, effectively avoiding problems such as bag opening misalignment, material displacement, and incomplete opening caused by manual bag placement and opening. This provides a reliable foundation for automated bagging operations, with a precision far exceeding that of manual operation. It effectively ensures the stability and smoothness of the packaging process, eliminating bagging jams, material misalignment, and other malfunctions. The bagging robot precisely grasps the lifted folded underwear and completes automated bagging. The bagging action is stable, precise, and efficient, replacing the random errors of manual bagging. Combined with the pressing module, the bagged packaging bag is pressed down and shaped, ensuring a tight fit between the underwear and the packaging bag. This prevents the finished underwear from shifting, loosening, or wrinkling inside the bag, significantly improving the appearance quality of the product packaging. Finally, the second conveying module accurately transports the packaging material to the sealing station, where the sealing module completes the standardized heat sealing operation. The seal is flat, firm, and has good sealing performance, completely solving quality problems such as uneven sealing force, edge wrinkles, and misalignment during manual sealing. This significantly reduces the packaging defect rate, standardizes product packaging, and improves the overall product quality. Therefore, the underwear folding and packaging machine of this invention can automatically fold and bag underwear without manual intervention in core processes such as folding, bagging, transfer, and sealing. It completely replaces the traditional purely manual underwear packaging operation mode, fundamentally solving many technical defects of traditional manual packaging, such as high labor costs, low production efficiency, poor operational continuity, and inconsistent product packaging standards. It can stably adapt to the needs of large-scale, automated production of underwear, greatly improving the overall production efficiency of the underwear packaging process and the overall automation level of the production line.

[0033] Please see Figures 1 to 4 In one embodiment, the folding module 300 includes a left-right folding component 301 and a front-back folding component 302. The left-right folding component 301 and the front-back folding component 302 are sequentially arranged on the mounting frame 1 along the conveying direction of the first conveying module 200. The front-back folding component 302 is used to drive the underwear 800 to flip and fold back and forth, and the left-right folding component 301 is used to drive the underwear 800 to flip and fold left and right. Through the step-by-step operation of the front-back and left-right folding components, a neat fold can be completed according to the standard folding process of underwear 800, adapting to the folding size and folding shape of various conventional underwear 800, ensuring that each pair of underwear 800 has uniform specifications and a flat appearance after folding, and eliminating problems such as skewing, wrinkles, and inconsistent sizes that occur during manual folding.

[0034] Specifically, in one embodiment, the front-to-back folding assembly 302 includes a front-to-back folding rotation drive mechanism 302a and a front-to-back folding flipping component 302b. The front-to-back folding rotation drive mechanism 302a is mounted on the mounting frame 1, and its output end is connected to the front-to-back folding flipping component 302b. The front-to-back folding rotation drive mechanism 302a drives the front-to-back folding flipping component 302b to rotate, causing it to pass through the first conveying module 200 and fold the front portion of the underwear 800 relative to its rear portion.

The bagging robot 500 can realize the automated and precise clamping, lateral movement, and filling of underwear 800, with smooth and efficient movements, replacing manual bagging and effectively improving bagging efficiency and finished product qualification rate.

[0048] Specifically, in one embodiment, the bagging clamping module 502 includes a bagging clamping moving drive component 502a, a fixed gripper 502b, and a moving gripper 502c. The bagging clamping moving drive component 502a is disposed on the bagging lateral movement drive module 501. The fixed gripper 502b is fixed to the fixed portion of the bagging clamping moving drive component 502a. The moving gripper 502c is fixed to the moving output end of the bagging clamping moving drive component 502a and is located above the fixed gripper 502b. The bagging clamping moving drive component 502a is used to drive the moving gripper 502c to rise and fall, so that the moving gripper 502c and the fixed gripper 502b cooperate to clamp or release the underwear 800. The upper and lower cooperating double gripper structure provides a stable clamping grip, can adapt to the thickness and shape of the folded underwear 800, and is not easy to slip or damage the underwear 800 during the clamping process. The opening and closing action is precise and controllable, and can stably complete the material picking and unloading bagging operation.

[0049] Please see Figure 6 and Figure 10 In one embodiment, the pressing module 8 includes a pressing moving drive component 81 and a pressing block 82. The output end of the pressing moving drive component 81 is connected to the pressing block 82. The pressing block 82 is located above the packaging bag filling station 22. The pressing block 82 is driven to descend by the pressing moving drive component 81 so that the pressing block 82 presses down on the packaging bag 900 containing the folded underwear 800 located at the packaging bag filling station 22. The pressing module 8 can press down and shape the packaging bag 900 after the underwear 800 is bagged. After the bagging robot 500 completes the filling action of the underwear 800, it forms a stable pressing and limiting effect on the packaging bag 900 and the internal folded underwear 800, effectively preventing the underwear 800 from shifting or being pulled out with the bagging robot 500 during the unloading process, or the packaging bag 900 from shifting, wrinkling, or deforming. This ensures that the product shape is neat after bagging, and at the same time provides sufficient working space for the bagging robot 500 to unload, ensuring smooth and jam-free automated bagging. The pressing and moving drive component 81 can use existing telescopic cylinders, but is not limited to this. It can be replaced with other drive structures such as electric push rods and linear modules according to actual production needs, making the equipment more adaptable and versatile.

[0050] Please see Figure 6 , Figure 12 and Figure 13In one embodiment, the sealing module 7 includes a lifting module 71, a lower clamping component 72, an upper clamping component 73, a lower heat sealing component 74, and an upper heat sealing component 75. The lifting module 71 is mounted on the mounting frame 1. The lower clamping component 72 is mounted on the lifting module 71, and the upper clamping component 73 is mounted on the mounting frame 1 and located above the lower clamping component 72. A bag mouth clamping space 76 for accommodating the sealing portion of the packaging bag 900 is formed between the lower clamping component 72 and the upper clamping component 73. The lower heat sealing component 74 is mounted on the lifting module 71 and located between the packaging bag sealing station 23 and the lower clamping component 72. The upper heat-sealing component 75 is mounted on the mounting frame 1 and located above the lower heat-sealing component 74. A heat-sealing space 77 for accommodating the sealing portion of the packaging bag 900 is formed between the lower heat-sealing component 74 and the upper heat-sealing component 75. The lower clamping component 72 and the lower heat-sealing component 74 are driven to rise by the lifting module 71, allowing them to support the sealing portion of the packaging bag 900. The upper clamping component 73 moves downward to cooperate with the lower clamping component 72 in clamping the sealing portion of the packaging bag 900. The upper heat-sealing component 75 moves downward to cooperate with the lower heat-sealing component 74 in heat-sealing the sealing portion of the packaging bag 900. The sealing module 7 adopts a first-clamping and positioning, then heat-sealing operation logic, which can first fix the sealing portion of the packaging bag 900, preventing displacement and wrinkling of the sealing portion during heat sealing, ensuring accurate heat sealing position and a flat and firm sealing edge, effectively improving sealing performance and finished product quality.

[0051] Specifically, in one embodiment, the lifting module 71 includes a lifting linear drive mechanism 711 and a lifting support block 712. The lifting linear drive mechanism 711 is mounted on the mounting frame 1, and the lifting support block 712 is slidably mounted on the mounting frame 1. The output end of the lifting linear drive mechanism 711 is connected to the lifting support block 712, and the lifting linear drive mechanism 711 is used to drive the lifting support block 712 to slide up and down. The lower clamping component 72 and the lower heat sealing component 74 are respectively mounted on the lifting support block 712. The lifting module 71 can synchronously drive the lower clamping component 72 and the lower heat sealing component 74 to rise and fall smoothly, accurately aligning with the sealing portion of the packaging bag 900, providing a stable support foundation for clamping and heat sealing operations.

[0052] Specifically, in one embodiment, the upper clamping assembly 73 includes a clamping and moving drive mechanism 731 and an upper clamping block 732. The clamping and moving drive mechanism 731 is mounted on the mounting frame 1, and its output end is connected to the upper clamping block 732. The upper clamping block 732 is located above the lower clamping assembly 72, and the clamping and moving drive mechanism 731 is used to drive the upper clamping block 732 to move downward. The upper heat-sealing assembly 75 includes a heat-sealing and moving drive mechanism 751 and an upper heat-sealing component 752. The heat-sealing and moving drive mechanism 751 is mounted on the mounting frame 1, and its output end is connected to the upper heat-sealing component 752. The upper heat-sealing component 752 is located above the lower heat-sealing assembly 74, and the heat-sealing and moving drive mechanism 751 is used to drive the upper heat-sealing component 752 to move downward. The upper clamping structure and the upper heat-sealing structure are driven independently and operate in stages, respectively completing the bag opening clamping and positioning and the heat-sealing operation, without interfering with each other.

[0053] Please see Figure 6 and Figure 12 In one embodiment, the underwear folding packaging machine further includes an exhaust pressure module 600 and a vacuum module 9. The exhaust pressure module 600 is mounted on the mounting frame 1 and located above the packaging bag sealing station 23. The exhaust pressure module 600 is used to press down on the packaging bag 900 so that the gas inside the packaging bag 900 is discharged through the bag opening. The vacuum module 9 is mounted on the mounting frame 1 and located on one side of the packaging bag sealing station 23. The vacuum module 9 is used to move through the bag opening heat sealing space 77 and the bag opening clamping space 76 and insert into the packaging bag 900 to vacuum the packaging bag 900. By cooperating with the exhaust pressure module 600 and the vacuum module 9, excess air inside the packaging bag 900 can be effectively discharged, preventing the finished packaging bag 900 from bulging, becoming fluffy and deformed, making the packaged product flatter and tighter. At the same time, it can improve the product's moisture-proof and dust-proof effect and extend the product's storage period.

[0054] Specifically, in one embodiment, the exhaust pressure module 600 includes an exhaust pressure moving drive component 601 and an exhaust pressure plate 602. The exhaust pressure moving drive component 601 is disposed on the mounting frame 1, and its output end is connected to the exhaust pressure plate 602. The exhaust pressure moving drive component 601 drives the exhaust pressure plate 602 to move downward, causing the exhaust pressure plate 602 to press down on the packaging bag 900. The plate-type pressure structure has a uniform force-bearing area, and the pressure process is stable. It can squeeze the air inside the packaging bag 900 as a whole, and the exhaust effect is uniform and thorough, without causing compression damage to the underwear 800 and the packaging bag 900.

[0055] Please see Figure 6 , Figure 12 and Figure 14In one embodiment, the vacuum module 9 includes a vacuum moving drive component 91, a transverse support 92, and a vacuum component 93. The vacuum moving drive component 91 is mounted on the mounting frame 1, and its output end is connected to the transverse support 92. The vacuum component 93 is mounted on the transverse support 92. The vacuum moving drive component 91 drives the transverse support 92 and the vacuum component 93 to move laterally, so that the vacuum component 93 passes through the bag opening heat sealing space 77 and the bag opening clamping space 76 and is inserted into the packaging bag 900, thereby enabling the vacuum component 93 to vacuum the packaging bag 900.

[0056] Please see Figure 12 , Figure 14 and Figure 15 In one embodiment, the underwear folding packaging machine further includes a bag opening flattening module 700, which is disposed on a transverse support 92. The bag opening flattening module 700 is driven by a vacuum moving drive component 91 to pass through the bag opening heat sealing space 77 and the bag opening clamping space 76 and insert into the packaging bag 900, so that the bag opening flattening module 700 flattens the bag opening of the packaging bag 900. By setting up the bag opening flattening module 700 and the vacuum module 9, the user can selectively use both modules. For example, the user can use only the bag opening flattening module 700 without the vacuum module 9, using only the bag opening flattening module 700 to flatten the bag opening of the packaging bag 900, and then using the exhaust pressing module 600, upper clamping component 73, lower clamping component 72, upper heat sealing component 75, and lower heat sealing component 74 to perform exhaust, clamping, and heat sealing processes on the packaging bag 900. Alternatively, the user can use only the vacuum module 9 without the bag opening flattening module 700, using only the vacuum module 9, exhaust pressing module 600, upper clamping component 73, lower clamping component 72, upper heat sealing component 75, and lower heat sealing component 74 to flatten the bag opening of the packaging bag 900. The clamping component 73, lower clamping component 72, upper heat sealing component 75, and lower heat sealing component 74 integrate the processes of vacuuming, venting, clamping, and heat sealing of the packaging bag 900. Furthermore, users can use the bag opening flattening module 700 and the vacuuming module 9 to flatten the bag opening before vacuuming. This effectively improves the problems of wrinkles, folds, and skewing at the bag opening of the packaging bag 900, keeping the bag opening flat and smooth. This facilitates the subsequent vacuuming operation of the vacuuming component 93 and lays a good foundation for the subsequent processes of the upper clamping component 73, lower clamping component 72, upper heat sealing component 75, and lower heat sealing component 74, improving the flatness of the seal from the source.

[0057] Specifically, in one embodiment, the bag opening flattening module 700 includes a flattening movement drive assembly 701, a first flattening member 702, and a second flattening member 703. The flattening movement drive assembly 701 is mounted on a transverse support 92. The first flattening member 702 and the second flattening member 703 are symmetrically arranged on the flattening movement drive assembly 701. The flattening movement drive assembly 701 drives the first flattening member 702 and the second flattening member 703 to move towards or away from each other. The first flattening member 702 and the second flattening member 703 are inserted into the packaging bag 900 and respectively abut against the opposite sides of the bag opening of the packaging bag 900 to flatten the bag opening of the packaging bag 900. The bag opening flattening module 700 adopts a symmetrical flattening structure, which can simultaneously open both sides of the bag opening, resulting in uniform force and good flattening effect. It can completely smooth out the bag opening wrinkles and provide good working conditions for subsequent precise heat sealing operations.

[0058] Specifically, in one embodiment, the leveling and moving drive assembly 701 includes a leveling drive cylinder 701a, a first leveling moving member 701b, a first leveling rack 701c, a leveling gear 701d, a second leveling moving member 701e, and a second leveling rack 701f. The leveling drive cylinder 701a is mounted on the transverse support 92, the first leveling moving member 701b is movably mounted on the transverse support 92, the output end of the leveling drive cylinder 701a is connected to the first leveling moving member 701b, and the first leveling rack 701c is fixed to the first leveling moving member 701b. The leveling gear 701d is rotatably connected to the transverse support 92. The first leveling rack 701c meshes with the leveling gear 701d on one side. The second leveling moving part 701e is movably mounted on the transverse support 92. The second leveling rack 701f is fixed to the second leveling moving part 701e and meshes with the leveling gear 701d on the other side. The first leveling part 702 is fixedly connected to the first leveling moving part 701b, and the second leveling part 703 is fixedly connected to the second leveling moving part 701e. The leveling moving drive assembly 701 uses a gear and rack meshing transmission method to achieve bidirectional synchronous leveling, with strong synchronicity of action, and can stably realize the bag opening and leveling operation.

[0059] Combination Figures 1 to 15 The working principle of the underwear folding and packaging machine of the present invention is as follows: During operation, the finished underwear 800 is continuously conveyed by the first conveying module 200, passing through the folding station 201 and the handling station 202 in sequence. At the folding station 201, the front and rear folding components 302 and the left and right folding components 301 sequentially complete the front and rear flip folding and the left and right centering folding of the underwear 800, realizing the standardized and neat folding of the underwear 800. After the folded underwear 800 is conveyed to the handling station 202 by the first conveying module 200, it is lifted by the top material module 400 below the handling station 202, so that the underwear 800 is removed from the upper surface of the first conveying module 200, providing conditions for material picking operation. At the same time, the packaging bag feeding module 3 picks up the packaging bags 900 stacked in the packaging bag storage rack 31 in batches through the packaging bag picking component 32, and automatically transports the packaging bags 900 to the packaging bag loading station 21 of the second conveying module 2. The second conveying module 2 drives the packaging bags 900 to the packaging bag filling station 22 and the packaging bag sealing station 23 in sequence. During the conveying process, the limiting component 24 limits and positions the packaging bags 900 throughout the process, and works with the support plate 11 to achieve stable support and prevent the packaging bags 900 from shifting and deforming. When the packaging bag 900 arrives at the packaging bag filling station 22, the first adsorption and bag pulling module 4 adsorbs the lower surface of the packaging bag 900 from below, and the second adsorption and bag pulling module 5 adsorbs and pulls the upper surface of the packaging bag 900 from above, completing the initial opening of the bag mouth. Then, the bag supporting module 6 drives the first bag supporting component 63 and the second bag supporting component 64 to insert into the bag mouth of the packaging bag 900 through the bag insertion moving drive component 61. Then, the bag supporting moving drive component 62 drives the two sets of bag supporting components to open in both directions, completely flattening and opening the bag mouth of the packaging bag 900. At this time, the bagging robot 500 clamps the lifted underwear 800 through the bagging clamping module 502, and moves laterally through the bagging lateral movement drive module 501 to accurately insert the folded underwear 800 into the opened packaging bag 900. After bagging, the pressing module 8 presses down on the packaging bag 900 to position the underwear 800 inside the bag, ensuring that the material fits neatly. Then, the bagging robot 500 releases the underwear 800 and exits the packaging bag 900. Subsequently, the second conveying module 2 conveys the packaging bag 900 containing the underwear 800 to the packaging bag sealing station 23. The vacuum moving drive component 91 drives the lateral movement bracket 92 to move laterally, causing the bag opening flattening module 700 and the vacuum component 93 to simultaneously pass through the bag opening heat sealing space 77 and the bag opening clamping space 76 and insert into the packaging bag 900. When the bag opening flattening module 700 needs to work, the flattening drive cylinder 701a of the bag opening flattening module 700 is activated. Through the transmission structure of the flattening gear 701d, the first flattening rack 701c, and the second flattening rack 701f, the first flattening component 702 and the second flattening component 703 are driven to open in opposite directions, so as to symmetrically flatten and straighten the bag opening of the packaging bag 900 and eliminate the problems of bag opening wrinkles and skewing.After the bag opening is leveled or when the bag opening leveling module 700 is not needed, the exhaust pressure moving drive component 601 drives the exhaust pressure plate 602 to move downward, pressing down on the main body of the packaging bag 900, squeezing out most of the air inside the packaging bag 900, achieving preliminary exhaust and shaping; at the same time, the vacuum component 93 is activated to perform deep vacuuming inside the packaging bag 900, thoroughly removing any residual air inside the bag, making the packaging bag 900 fit tightly against the surface of the folded underwear 800. Subsequently, the lifting module 71 drives the lifting support block 712 to rise, causing the lower clamping component 72 and the lower heat sealing component 74 to rise synchronously, providing stable support for the sealed part of the packaging bag 900. The clamping moving drive mechanism 731 drives the upper clamping block 732 to move downward, cooperating with the lower clamping component 72 to stably clamp and fix the sealed part of the packaging bag 900, locking the shape of the bag opening and preventing the bag opening from loosening and springing back. Finally, the heat-sealing moving drive mechanism 751 drives the upper heat-sealing component 752 to move downward, and cooperates with the lower heat-sealing component 74 to accurately heat-seal the flat and fixed packaging bag 900, realizing the automated, standardized and efficient production operation of the underwear 800 packaging.

[0060] In summary, the underwear bag sealing mechanism 100 of the present invention, by setting up a first conveying module 200, a folding module 300, a top-feeding module 400, a second conveying module 2, a packaging bag feeding module 3, a first suction-pulling bag module 4, a second suction-pulling bag module 5, a bag-supporting module 6, a bag-filling robot 500, a pressing module 8, and a sealing module 7, constructs a fully automated production line packaging system integrating underwear 800 conveying, folding, lifting and handling, packaging bag 900 feeding and conveying, bag pulling and supporting, automatic bag filling, pressing and shaping, sealing and storage, wherein the first conveying module 200... The system can stably transport 800 finished underwear pieces and precisely divide the folding station 201 and the handling station 202. Working with the folding module 300, it completes standardized folding operations for the 800 underwear pieces, eliminating problems such as inconsistent sizes, messy wrinkles, and inconsistent specifications caused by manual folding. Simultaneously, the top-loading module 400 lifts the material, providing precise operating conditions for automated material handling and bagging. Meanwhile, the second conveying module 2, in conjunction with the packaging bag feeding module 3, achieves automated feeding and station transfer of packaging bags 900, relying on the bidirectional suction and pulling of the first suction bag module 4 and the second suction bag module 5. The bag-opening module 6 works collaboratively to accurately and stably open the 900 bag openings, effectively avoiding problems such as bag opening misalignment, material displacement, and incomplete opening caused by manual bag placement and opening. This provides a reliable foundation for automated bagging operations, with overall operational precision far exceeding that of manual operation, effectively ensuring the stability and smoothness of the packaging process and eliminating bagging jams and material misalignment. The 500-unit bagging robot precisely grasps the lifted folded underwear 800 and completes automated bagging, with stable, precise, and efficient bagging action, replacing the arbitrary errors of manual bagging. Combined with the pressing module... The packaging bags 900 after being filled are pressed down and shaped, which ensures that the underwear 800 fits tightly with the packaging bag 900, preventing the finished underwear 800 from shifting, loosening, or wrinkling inside the bag, and greatly improving the appearance quality of the product packaging. Finally, the second conveying module 2 accurately conveys the packaging materials to the packaging bag sealing station 23, where the standardized heat sealing operation is completed by the sealing module 7. The seal is flat, firm, and has good sealing performance, which completely solves the quality problems such as uneven sealing force, edge wrinkles, and shifting or missing seals caused by manual sealing, significantly reducing the packaging defect rate, unifying product packaging standards, and improving the overall quality of the product. Therefore, the underwear folding and packaging machine of the present invention can automatically fold and bag underwear 800 without the need for manual participation in core processes such as folding, bagging, transfer, and sealing. It completely replaces the traditional purely manual underwear 800 packaging operation mode, fundamentally solving many technical defects of traditional manual packaging such as high labor costs, low production efficiency, poor operation continuity, and inconsistent product packaging standards. It can stably adapt to the large-scale automated production needs of underwear 800, greatly improving the overall production efficiency of the underwear 800 packaging process and the overall automation level of the production line.

[0061] The above-disclosed embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of the present invention. Therefore, any equivalent variations made in accordance with the claims of the present invention are still within the scope of the present invention.
