Description

Technical Field

[0001] This utility model relates to a hanging assembly line for sewing operations in the clothing and footwear industry. Background Technology

[0002] Patent No. 202223564708.9 discloses an intelligent hanging conveyor device for garment production, including a mounting bracket. The mounting bracket is equipped with a conveying mechanism and a driving mechanism. A hanging mechanism is located on the outer side of the conveying mechanism. The driving mechanism includes a connecting plate, a mounting base, a drive motor, a drive wheel, a drive belt, a photoelectric counter, and a guide rail. By incorporating the driving mechanism, the photoelectric counter counts the garments, and the drive belt, in conjunction with the guide rail, clamps the hanging mechanism and drives it upwards, automating the garment loading process. The conveying mechanism, in conjunction with the driving mechanism, enables intelligent hanging and transport of garments, improving the device's practicality, replacing manual operation, and increasing the overall efficiency of garment processing. The photoelectric counter detects the quantity of garments being processed, facilitating real-time monitoring and management of the garment processing status, thus enhancing the device's intelligence.

[0003] Existing patented intelligent hanging conveyor technology requires the workstation guide rail to extend only from the input end to the output end. The guide rail is arranged horizontally at the bottom of the workstation via a winding, rotating mechanism. This design occupies a large volume of the overall device and also requires space for sewing processing positions. Due to the large space occupied by each workstation, the number of workstations can be limited, thus hindering work efficiency. Furthermore, existing hanging systems have high space requirements, making them unsuitable for installation in many low-ceilinged factory buildings, thus affecting their application. Summary of the Invention

[0004] This utility model addresses the aforementioned technical problems by providing a suspended assembly line that places the workstation inside the main rail, saving installation space and adapting to the requirements of suspended layout in smaller spaces, thus improving the applicability of suspended installation.

Each workstation includes a first rail and a second rail fixed on a mounting bracket. A limiting device for restricting the movement of the hanging wheels and a lifting self-locking device for transferring the hanging wheels are provided between the first rail and the second rail. A sewing station is provided below the lifting self-locking device.

[0006] To optimize the above technical solution, the present invention also includes the following improved technical solutions.

[0007] The first track is equipped with an entry device that connects to the main track at its front end, and the second track is equipped with an exit device that connects to the main track at its rear end.

[0008] The aforementioned second track has a first guide section, a lifting section, and a second guide section, with a lifting device for lifting the hanging wheel provided on one side of the lifting section.

[0009] The first track is provided with one or more of the aforementioned limiting devices, and the second track is provided with one or more of the aforementioned limiting devices.

[0010] The aforementioned lifting self-locking device includes a first mounting base disposed on the lifting profile. The first mounting base is provided with a movable track for the hanging wheel to pass through. A first rotating shaft and a second rotating shaft are disposed below the first mounting base. One end of the first rotating shaft is provided with a sector gear, and one end of the second rotating shaft is provided with a first gear that meshes with the sector gear. A lever is disposed on the first rotating shaft, and a return spring is disposed on the second rotating shaft. A first lever and a second lever for locking the hanging wheel are disposed at the front end of the first mounting base. The first lever and the second lever are rotatably connected to the second rotating shaft.

[0011] The second rotating shaft is provided with a connecting block at one end, one end of the return spring is connected to the first mounting base, and the other end of the return spring is connected to the connecting block.

[0013] One end of the lever is sleeved on the first rotating shaft, and the other end of the lever is provided with a rotating wheel; the lever is provided with a screw for limiting the swing amplitude of the lever.

[0014] The aforementioned lifting profile has a first mounting column on one side, which is fixedly connected to the mounting bracket for the suspended production line. The lifting profile is provided with a pulley assembly that moves up and down along the first mounting column, and a rodless cylinder that drives the lifting profile to move up and down is provided inside the first mounting column.

[0015] Compared with the prior art, the hanging production line of this utility model uses a lifting self-locking device to lift the hanging wheels in two stages within the workstation after the hanging clothes rack enters the workstation, which facilitates the operation of the sewing station below. This allows for a large height difference between the first and second tracks in the workstation and the sewing station, saving the space occupied by the track layout and improving the space utilization rate.

[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0023] Figures 1 to 6 The diagram shown is a structural schematic of this utility model.

[0024] The attached figures are labeled as follows: main rail 1, first track 2, second track 3, first guide section 3a, lifting section 3b, second guide section 3c, lifting profile 4, first mounting base 5, movable track 6, first rotating shaft 7, second rotating shaft 8, sector gear 9, first gear 10, lever 11, first lever 12, second lever 13, second mounting base 14, connecting block 15, third rotating shaft 16, first crank 17, fourth rotating shaft 18, second crank 19, wheel 20, screw 21, first mounting post 22, mounting bracket 23, pulley assembly 24, rodless cylinder 25, connecting frame 26, limit mounting base 27.

[0025] This utility model discloses a suspended assembly line, comprising a main rail 1 and several workstations distributed inside the main rail 1. Each workstation includes a first track 2 and a second track 3 fixed on a mounting bracket 23. The front end of the first track 2 is equipped with an entry device that connects to the main rail 1, and the rear end of the second track 3 is equipped with an exit device that connects to the main rail 1. A limiting device for restricting the movement of the suspended wheels and a lifting self-locking device for transferring the suspended wheels are provided between the first track 2 and the second track 3. A sewing station is provided below the lifting self-locking device.

[0026] The hanging wheel enters the first track 2 from the main track 1. The limiting device between the first track 2 and the second track 3 restricts the hanging wheel at the lifting self-locking device. The lifting self-locking device drives the hanging wheel downward so that the sewing station can process the descending hanging garment. Subsequently, the lifting self-locking device drives the hanging wheel upward until it connects with the second track 3. The limiting device between the first track 2 and the second track 3 is released, and the hanging wheel enters the second track 3.

[0027] The second track 3 has a first guide section 3a, a lifting section 3b, and a second guide section 3c. A lifting device for lifting the suspended wheel is provided on one side of the lifting section 3b. The suspended wheel enters the second track 3 along the first guide section 3a, and the lifting device transports the suspended wheel upward along the lifting section 3b to the second guide section 3c. Finally, the suspended wheel is output from the second guide section 3c to the main track 1.

[0028] The first track 2 is equipped with one or more limiting devices to restrict the movement of the hanging wheels. These limiting devices control the movement of the hanging wheels on the first track 2, thereby controlling the number of hanging wheels entering the next process. In this embodiment, the first track 2 is equipped with two limiting devices, and the number of limiting devices can be adjusted according to actual conditions.

[0029] The second track 3 is provided with one or more limiting devices for restricting the movement of the hanging wheels. In this embodiment, the second guide section 3c of the second track 3 is provided with a limiting device to control the number of hanging wheels entering the main track 1. The number of limiting devices can be adjusted according to the actual situation.

[0030] The lifting self-locking device for the suspended assembly line includes a first mounting base 5 mounted on the lifting profile 4. The first mounting base 5 has a movable track 6 for the suspension wheel to rest on. Below the first mounting base 5 are a first rotating shaft 7 and a second rotating shaft 8. One end of the first rotating shaft 7 is equipped with a sector gear 9, and one end of the second rotating shaft 8 is equipped with a first gear 10 that meshes with the sector gear 9. A lever 11 is mounted on the first rotating shaft 7, and a return spring is mounted on the second rotating shaft 8. The front end of the first mounting base 5 is equipped with a first lever 12 and a second lever 13 for locking the suspension wheel. The first lever 12 and the second lever 13 are rotatably connected to the second rotating shaft 8.

[0031] When the two ends of the movable track 6 are connected to the first track 2 and the second track 3, the lever 11 contacts the bottom surface of the limiting mounting seat 27 of the limiting device. The lever 11 drives the sector gear 9 on the first rotating shaft 7 to rotate. The sector gear 9 rotates in conjunction with the first gear 10 of the second rotating shaft 8. The second rotating shaft 8 drives the first lever 12 and the second lever 13 to open outward. At this time, the return spring deforms. During the descent, the angle formed between the lever 11 and the bottom surface of the limiting mounting seat 27 gradually increases until it loses contact. The return spring gradually returns to its original position. The return spring drives the second rotating shaft 8 to rotate, and the first lever 12 and the second lever 13 close inward to lock the hanging wheel.

[0032] A second mounting base 14 is provided below the first mounting base 5, and the first rotating shaft 7 and the second rotating shaft 8 are rotatably mounted in the second mounting base 14. A connecting block 15 is provided at one end of the second rotating shaft 8, one end of the return spring is connected to the first mounting base 5, and the other end of the return spring is connected to the connecting block 15.

[0033] The first lever 12 is rotatably mounted on the front end of the first mounting base 5 via the third rotating shaft 16, and one end of the first lever 12 is connected to the connecting block 15 via the first crank 17. The second lever 13 is rotatably mounted on the front end of the first mounting base 5 via the fourth rotating shaft 18, and one end of the second lever 13 is connected to the connecting block 15 via the second crank 19.

[0034] One end of the lever 11 is sleeved on the first rotating shaft 7, and the other end of the lever 11 is provided with a rotating wheel 20. The rotating wheel 20 can contact the bottom surface of the limiting mounting seat 27 of the limiting device to reduce wear between parts.

[0035] After the rotating wheel 20 of lever 11 disengages from the bottom surface of the limiting mounting base 27 of the limiting device, if the first lever 12 and the second lever 13 still lock the hanging wheel inward, it may damage the parts. A screw 21 is inserted through lever 11 to limit the swing amplitude of lever 11. By limiting the swing amplitude of lever 11, the inward closing amplitude of the first lever 12 and the second lever 13 is also limited. When the bottom of screw 21 abuts against the first mounting base 5, lever 11 can no longer close inward, and the first lever 12 and the second lever 13 stop closing inward.

[0036] The lifting profile 4 has a first mounting post 22 on one side, which is fixedly connected to the mounting bracket 23. The lifting profile 4 is provided with a pulley assembly 24 that moves up and down along the first mounting post 22. The first mounting post 22 is provided with a rodless cylinder 25 that drives the lifting profile 4 to move up and down. The rodless cylinder 25 is connected to the lifting profile 4 through a connecting frame 26, and the rodless cylinder 25 can drive the lifting profile 4 to move up and down along the first mounting post 22.

[0037] The preferred embodiment of this utility model has been described, and various changes or modifications made by those skilled in the art will not depart from the scope of this utility model.
