Description

Technical Field

[0001] This invention relates to the field of garment manufacturing technology, and in particular to a hanging system for garment manufacturing. Background Technology

[0002] In garment production and processing, it is often necessary to transfer, temporarily store, and adjust the posture of fabrics, cut pieces, or semi-finished products between different workstations, such as in sewing, ironing, inspection, and packaging. Overhead conveyor systems are widely used in modern garment production lines due to their high space utilization and smooth flow.

[0003] Currently, most common garment hanging systems are hanger-type conveyor chains, which use hooks or clips to hold garments at specific locations such as collars and waistbands, transporting them in a vertically suspended state. This type of system has the following drawbacks: 1. Fabric is prone to stretching and deformation: When using single or two-point suspension for lightweight or elastic fabrics such as silk, knitwear, and chiffon, the fabric will naturally sag under its own weight, resulting in local stretching, dimensional instability, and even wrinkles that are difficult to eliminate, affecting the quality of subsequent processing.

[0004] 2. Inability to lay the fabric flat: Many processes (such as pattern making, positioning, reverse sewing, ironing) require the fabric to be kept flat. However, the traditional hanging method leaves the fabric hanging freely, requiring operators to repeatedly flatten it, which reduces production efficiency.

[0005] 3. High cost of multi-station stepper drive: In order to realize the step movement of multiple suspension units according to the station spacing, the existing technology often uses linear motor modules, multiple servo motors or cylinders in series, which leads to high equipment cost, complex electrical control system and difficult maintenance.

[0006] 4. Lack of independent rotation function or poor synchronization of suspension units: Some processes require the fabric to be flipped at a certain angle (such as from the front to the back for operation). If each suspension unit is equipped with a separate rotation motor, it will not only increase the cost, but also make it difficult to ensure that all units rotate at the same angle. If manual flipping is used, the labor intensity is high and the efficiency is low.

[0007] 5. Inflexible adjustment of workstation spacing and quantity: The workstation spacing of traditional hanging systems is usually fixed and cannot be quickly adjusted according to the actual layout of the production line or the length of different garment parts, resulting in poor equipment adaptability.

[0008] Therefore, there is an urgent need for a hanging system for garment production that can achieve flat storage of fabric, low-cost step conveying, synchronous flipping, and a compact structure. Summary of the Invention

[0009] The purpose of this invention is to provide a suspension system for garment production, which solves the problems of existing garment suspension systems, such as fabric being easily stretched and deformed and unable to be laid flat, high cost and complex control of multi-station stepper drive, and difficulty in synchronizing the rotation angles of multiple suspension units.

[0010] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The present invention discloses a hanging system for garment production, comprising a support mechanism, wherein a plurality of movable seats are provided on the support mechanism, and a rotatable fixed frame is provided below the movable seats. A plurality of pull-out frames are provided inside the fixed frame, and a plurality of clamps for clamping fabric are provided on the inner wall of the pull-out frames. The support mechanism is further provided with a first driving mechanism for driving the plurality of movable seats to move and a second driving mechanism for driving the fixed frame to rotate.

[0011] Furthermore, the support mechanism includes a support frame, and two mounting plates are symmetrically arranged on the top of the support frame. The top surface, front side, and rear side of the two mounting plates are respectively provided with a top plate, a front side plate, and a rear side plate.

[0012] Furthermore, the first driving mechanism includes a driving rod rotatably disposed between the two mounting plates. The driving rod includes a threaded section and a smooth section connected together. One of the movable seats is provided with a lead screw nut threadedly connected to the threaded section, and the other movable seats are provided with through holes for the threaded section and the smooth section to pass through. Adjacent movable seats are connected by a linkage assembly. A first driving motor for driving the driving rod to rotate is provided on the mounting plate. A guide rod is provided between the two mounting plates and on one side of the driving rod, and the movable seat is provided with a guide hole for the guide rod.

[0013] Furthermore, the linkage assembly includes a first swing rod, which is rotatably disposed on the top surface of the movable seat. The first swing rods on the top of two adjacent movable seats are hinged together. A second swing rod is rotatably disposed on one of the mounting plates, and the second swing rod is hinged together with the adjacent first swing rod.

[0014] Furthermore, the second driving mechanism includes a sliding rod rotatably disposed between the two mounting plates. A sliding key is provided on the surface of the sliding rod. A worm gear is provided on the front side of the movable seat, and the worm gear is slidably sleeved on the sliding rod. A groove matching the sliding key is provided on the inner wall of the worm gear's central hole. A worm wheel meshing with the worm gear is provided inside the movable seat. A first connecting shaft is provided at the center of the worm wheel, and a first bevel gear is provided on the first connecting shaft. A second connecting shaft is provided on the top surface of the fixed frame, and a second bevel gear meshing with the first bevel gear is provided on the second connecting shaft. A second drive motor for driving the sliding rod to rotate is provided on the mounting plate.

[0015] Furthermore, a mounting shell is provided on the front side of the movable seat, and a first receiving cavity is provided inside the mounting shell for accommodating the worm and the worm wheel.

[0016] Furthermore, a fixed shell is provided on the front side of the mounting shell, and the second connecting shaft is rotatably connected to the fixed shell.

[0017] Furthermore, a vehicle body is provided below the support mechanism, and push rods are symmetrically arranged on both sides of the vehicle body.

[0018] Furthermore, the upper and lower inner walls of the fixed frame are each provided with a number of drawer slides, and the pull-out frame is located between the upper and lower drawer slides.

[0019] Furthermore, several clips are provided on the upper, lower, left, and right inner walls of the pull-out frame.

[0020] Compared with the prior art, the beneficial technical effects of the present invention are as follows: 1. Compact structure and low cost: Only one primary drive motor is needed to achieve synchronous, equidistant stepping movement of multiple moving seats, avoiding multiple servo motors or complex pneumatic / hydraulic systems, thus reducing equipment manufacturing costs and electrical control complexity. The linkage mechanism adopts a simple linkage hinge form, which is robust, durable, and easy to maintain.

[0021] 2. One source, multiple drives, good synchronization: The design of driving multiple worm gears through sliding rod and sliding key allows one second drive motor to control all fixed frames to rotate synchronously. The rotation angle of each fixed frame is completely consistent, and no individual calibration is required. It is very suitable for assembly line scenarios that require all suspension units to operate at the same angle (such as uniformly flipping the fabric for reverse processing).

[0022] 3. High-quality fabric storage: The pull-out frame structure with four-wall clips enables "flat" hanging storage of fabrics, rather than the point hanging of traditional hangers. This method can fundamentally avoid the stretching and deformation of fabrics caused by their own weight, and is especially suitable for easily deformable fabrics such as silk and knitwear. At the same time, the pull-out design greatly facilitates the operation of workers to pick up and put down the fabrics, which is in line with ergonomics.

[0023] 4. Flexible expansion and strong adaptability: By changing the number and length of the linkage rods, as well as the length of the threaded section on the drive rod, the number of moving seats and the station spacing can be easily adjusted to adapt to production lines of different sizes and garment parts of different lengths.

[0024] 5. Easy to move and reliable positioning: The bottom of the vehicle is equipped with both moving wheels and universal wheels with brakes, which allows the entire suspension system to be moved as a whole to different workshops or production lines and quickly and stably fixed.

[0028] like Figure 1-9 As shown, a hanging system for garment production includes a support mechanism. The support mechanism has several movable seats 8, and a rotatable fixed frame 19 is located below each movable seat 8. The fixed frame 19 contains several pull-out frames 21, and the inner walls of the pull-out frames 21 are equipped with several clamps 22 for clamping fabric. The support mechanism also includes a first drive mechanism for driving the movable seats 8 to move and a second drive mechanism for driving the fixed frame 19 to rotate. In this embodiment, the number of movable seats 8 is three.

[0029] The support mechanism includes a support frame 2, and two mounting plates 3 are symmetrically connected to the top of the support frame 2. The top surface, front side and rear side of the two mounting plates 3 are respectively connected to a top plate 23, a front side plate 25 and a rear side plate 24. The front side plate 25 is lower in the vertical direction to avoid affecting the movement of the movable seat 8.

[0030] The first driving mechanism includes a driving rod 4 rotatably mounted between the two mounting plates 3 via bearings. The driving rod 4 includes a threaded section 401 and a smooth section 402 connected together. A lead screw nut 11 is mounted on the leftmost movable seat 8, and the lead screw nut 11 is threadedly connected to the threaded section 401. The other two movable seats 8 are provided with through holes 803 for the threaded section 401 and the smooth section 402 to pass through. The two adjacent movable seats 8 are connected by a linkage assembly. A first driving motor 5 for driving the driving rod 4 to rotate is mounted on the mounting plate 3 on the left. A guide rod 6 is connected between the two mounting plates 3 and on one side of the driving rod 4. The movable seat 8 is provided with a guide hole 804 for the guide rod 6.

[0031] Specifically, the linkage component includes a first swing rod 9, which is rotatably mounted on the top surface of the movable seat 8 via a pivot. The first swing rods 9 on the top of two adjacent movable seats 8 are hinged together. A second swing rod 10 is rotatably mounted on the mounting plate 3 on the left side via a pivot. The other end of the second swing rod 10 is hinged together with the adjacent first swing rod 9.

[0032] This system employs a combination of "single lead screw drive + linkage assembly" to achieve intermittent, equally spaced step-by-step movement of multiple movable seats 8. Specifically, the first drive motor 5 drives the drive rod 4 to rotate, and its threaded section 401 engages only with the lead screw nut 11 on the leftmost movable seat 8, driving this movable seat 8 to move to the right along the guide rod 6. Simultaneously, the movable seats 8 are hinged together by the first swing rod 9, and the leftmost movable seat 8 is hinged to the left mounting plate 3 by the second swing rod 10. When the leftmost movable seat 8 moves to the right, the second swing rod 10 swings outward, pushing the first swing rod 9 hinged to it, thereby transmitting the thrust sequentially to the subsequent movable seats 8. Since the lengths of each hinge rod are equal and their installation positions correspond, this linkage assembly ensures that all movable seats 8 can move to the right at the same interval and the same speed. This design avoids equipping each movable seat 8 with an independent lead screw or linear motor, reducing manufacturing costs and the complexity of the control system.

[0033] like Figure 7 As shown, the second driving mechanism includes a sliding rod 7 rotatably mounted between the two mounting plates 3 via bearings. A sliding key 701 is connected to the surface of the sliding rod 7. A worm gear 12 is provided on the front side of the movable seat 8. The worm gear 12 is slidably sleeved on the sliding rod 7. A groove matching the sliding key 701 is opened on the inner wall of the central hole of the worm gear 12. A worm wheel 13 meshing with the worm gear 12 is provided inside the movable seat 8. A first connecting shaft 14 is installed at the center of the worm wheel 13. The first connecting shaft 14 is rotatably connected to the movable seat 8 via bearings. The first connecting shaft 14 extends to the front side of the movable seat 8. A first bevel gear 15 is installed on the first connecting shaft 14. A second connecting shaft 16 is connected to the top surface of the fixed frame 19. A second bevel gear 17 meshing with the first bevel gear 15 is installed on the second connecting shaft 16. A second drive motor 18 for driving the sliding rod 7 to rotate is installed on the mounting plate 3 located on the right side.

[0034] A mounting shell 801 is detachably mounted on the front side of the movable seat 8 by bolts. The mounting shell 801 has a first receiving cavity for accommodating the worm gear 12 and the worm wheel 13. A fixed shell 802 is bolted to the front side of the mounting shell 801. The second connecting shaft 16 is rotatably connected to the fixed shell 802 by a bearing. The second connecting shaft 16 extends to the bottom of the fixed shell 802 and is connected to the top surface of the fixed frame 19.

[0035] Each fixed frame 19 below the movable seat 8 has independent rotational drive capability, but all fixed frames 19 share the same power source—the second drive motor 18. The second drive motor 18 drives the sliding rod 7 to rotate at a constant speed. The sliding rod 7 drives all the worm gears 12 sleeved on it to rotate synchronously through the sliding key 701. Each worm gear 12 meshes with the worm wheel 13 in the corresponding movable seat 8, transmitting the rotational motion to the first connecting shaft 14 and the first bevel gear 15. After being reversed by the second bevel gear 17, it finally drives the fixed frame 19 to rotate around the axis of the second connecting shaft 16. Since the worm gear 12 and the sliding rod 7 are connected by a sliding key, when the movable seat 8 moves laterally, the worm gear 12 can slide freely along the sliding rod 7, thus realizing a follow-up rotational drive of "one power source driving multiple independent moving units", which ensures synchronicity and allows each unit to move independently.

[0036] A vehicle body 1 is located below the support mechanism, and a support frame 2 is connected to the top surface of the vehicle body 1. Push rods 101 are symmetrically connected to both sides of the vehicle body 1, and a movable wheel is installed at the middle of the bottom of the vehicle body 1. Both sides of the movable wheel are equipped with universal wheels with brakes. The configuration of movable wheels and universal wheels with brakes at the bottom of the vehicle body allows the suspension system to be moved as a whole to different workshops or production lines and quickly and stably fixed, improving equipment utilization.

[0037] The upper and lower inner walls of the fixed frame 19 are each equipped with a plurality of drawer slides 20, and the pull-out frame 21 is connected between the upper and lower drawer slides 20. The upper, lower, left, and right inner walls of the pull-out frame 21 are each connected with a plurality of clips 22.

[0038] The fixed frame 19 adopts a "drawer-type" structure inside, and the pull-out frame 21 is installed through the drawer slides 20 set at the top and bottom. The pull-out frame 21 can be pulled outward, making it convenient for workers to clamp or remove the fabric in the best operating position. Multiple clips 22 are set on the inner walls (top, bottom, left, and right) of the pull-out frame 21, which can fix the fabric flat and taut on all four sides, preventing the fabric from wrinkling, slipping, or tangling due to gravity or shaking during hanging and transportation. This vertical layering and clamping method is especially suitable for thin or drapey fabrics that require high flatness.

[0039] When the suspension system of the present invention is in operation, it realizes the conveying, turning and inter-station transfer of fabric according to the following steps: Step 1: Initial clamping (station 1) The system is in its initial position, with all movable seats 8 on the far left (or at the set starting end). In front of the first fixed frame 19, the operator manually pulls the pull-out frame 21 outward along the drawer slide rail 20 to the limit position, and clamps the edges of the fabric or garment piece to be processed one by one with the clips 22 on the inner wall of the pull-out frame 21 to ensure that the fabric is evenly stressed on all four sides and the surface is flat; after clamping, the pull-out frame 21 is pushed back into the fixed frame 19.

[0040] Step 2: Stepping conveyor to the next workstation The first drive motor 5 is started, and the drive rod 4 rotates. The leftmost movable seat 8 moves to the right under the action of the lead screw nut 11. Through the linkage of the second swing rod 10 and the first swing rod 9, adjacent movable seats 8 are pushed in sequence. All movable seats 8 move one station distance to the right at the same speed and spacing. At this time, the original first movable seat 8 moves to the second station position, the second moves to the third station, and so on. The first drive motor 5 stops, and the positioning of the movable seat 8 is completed.

[0041] Step 3: Station Operation (Rotation / Machining) Once the moving seat 8 reaches the designated workstation, if the workstation requires different angle operations on the fabric (such as double-sided inspection, sewing symmetrical parts, ironing the reverse side, etc.), the second drive motor 18 can be activated. The second drive motor 18 drives the sliding rod 7 and all the worm gears 12 to rotate, which in turn drives each fixed frame 19 to rotate synchronously by a preset angle (such as 90° or 180°) through the worm wheel 13 and bevel gear pair. Due to the self-locking characteristic of the worm wheel and worm gear, the fixed frame 19 can stably maintain its posture after rotation, and the operator can pull out the pull-out frame 21 again to perform the corresponding process on the fabric. Each workstation can be operated independently for different times without interference, because the stepping action of the moving seat is intermittent.

[0042] Step 4: Unloading the finished product and resetting the system At the last workstation (such as the inspection and packaging station), the operator removes the finished fabric from the clamp 22 and pushes the empty pull-out frame 21 back. After all the moving seats 8 have finished unloading in sequence, the first drive motor 5 reverses, driving the leftmost moving seat 8 to return to the left. The linkage mechanism then swings in the opposite direction, pushing all the moving seats 8 to move to the left synchronously until they all return to the starting position, and the next work cycle begins.

[0043] If the production line requires a different number of movable seats, it can be modularly expanded by changing the length and number of the linkage rods, as well as the length ratio of the threaded section to the smooth section on the drive rod.

[0044] This invention, with its simple and efficient mechanical transmission structure, enables smooth fabric transport, flexible steering, and high-quality storage during garment production, demonstrating significant practicality and economy.
