Description

Technical Field

[0001] This utility model relates to the field of shoemaking equipment technology, and in particular to a multi-station rotary automated workstation for sewing shoe uppers. Background Technology

[0002] In the footwear industry, upper sewing is a crucial step in the production process, and its quality and efficiency directly impact the overall performance and production cycle of the finished shoes. Traditional upper sewing typically relies on manual operation or semi-automated equipment. While this method can meet certain production needs, it suffers from low efficiency, high labor intensity, and inconsistent product quality. As the manufacturing industry moves towards automation and intelligence, the market demand for efficient and precise automated sewing equipment is increasing daily.

[0003] Currently, some companies are attempting to introduce automated sewing equipment to improve production efficiency. However, most existing automated equipment is designed for single workstations, completing only one process at a time. This results in low equipment utilization, and the transitions between processes require additional manual intervention, making continuous production difficult. Furthermore, existing automated sewing workstations typically lack flexibility and struggle to adapt to the diverse production needs of different shoe upper styles. These issues limit further improvements in the footwear industry's production efficiency and increase production costs.

[0015] This utility model provides a multi-station rotary automated workstation for sewing shoe uppers, combined with an attached... Figure 1 To be continued Figure 3 The specific embodiments of this utility model will be described in detail below. For example... Figure 1As shown, the overall structure of the workstation includes a base 1, a rotating disk 2, a workstation module 3, a sewing machine head 4, a drive mechanism 5, a positioning mechanism 6, a buffer mechanism 7, and a support frame 8. The base 1 is the foundation component of the entire workstation, used to fix it to the ground or workbench. It has mounting holes 101 at its four corners, allowing it to be securely installed on the ground or workbench using bolts or other fasteners, thus ensuring the stability of the entire device. The rotating disk 2 is connected to the base 1 via a central shaft and can rotate around this shaft. Reinforcing ribs 201 are provided at the bottom of the rotating disk 2, evenly distributed radially to enhance its structural strength and prevent deformation during high-speed operation. Furthermore, four limiting grooves 202 are provided on the upper surface of the rotating disk 2, evenly distributed around its central shaft, to limit the movement range of the workstation module 3, ensuring its stability during rotation.

[0016] Four workstation modules 3 are evenly distributed along the edge of the rotating disk 2, with each module 3 centered on the central axis of the rotating disk 2.

[0018] like Figure 2 As shown, the lifting mechanism 9 is located below the workstation module 3 and includes a lifting cylinder 901 and a lifting rod 902. The lifting cylinder 901 is fixedly connected to the bottom of the rotating disk 2, and the lifting rod 902 is perpendicular to the rotating disk 2, with its first end connected to the piston rod of the lifting cylinder 901. The linkage mechanism 10 includes a first link, a second link, and a third link. The first end of the first link is connected to the second end of the lifting rod 902. The second link is parallel to the rotating disk 2, with its first end connected to the second end of the first link. The third link is perpendicular to the rotating disk 2, with its first end connected to the second end of the second link. The clamping mechanism 11 is located above the workstation module 3 and includes a pressure plate 1101 and a clamping spring 1102. The pressure plate 1101 contacts the upper surface of the workstation module 3, and one end of the clamping spring 1102 is fixedly connected to the pressure plate 1101, while the other end is fixedly connected to the third link of the linkage mechanism 10. The guide mechanism 12 is located on both sides of the lifting mechanism 9, including guide column 1201 and guide sleeve 1202. The guide column 1201 is perpendicular to the rotating disk 2, and its first end is fixedly connected to the bottom of the rotating disk 2. The guide sleeve 1202 is sleeved on the surface of the guide column 1201 and fixedly connected to the lifting rod 902 to guide the vertical movement of the lifting rod 902 and ensure that the lifting process is smooth and reliable.

[0019] Two auxiliary support frames 13 are located below the rotating disk 2, both perpendicular to the base 1. The first end of each auxiliary support frame 13 is fixedly connected to the edge of the base 1, and the second end is fixedly connected to the bottom of the rotating disk 2. The two auxiliary support frames 13 are symmetrically arranged around the drive mechanism 5 to further enhance the stability of the rotating disk 2. Two elastic connectors 14 are also present. The first end of each elastic connector 14 is hinged to the first end of each auxiliary support frame 13, and the second end of each elastic connector 14 is sleeved on the surface of the lifting rod 902, providing additional cushioning during lifting. Two synchronous belts 15 are also present. One end of each synchronous belt 15 is fixedly connected to the surface of the lifting rod 902, and the other end is connected to the corresponding workstation module 3. The two synchronous belts 15 are symmetrically arranged around the drive mechanism 5 to ensure the synchronicity of the workstation modules 3 during lifting. There are six shock-absorbing pads 16, which are fixedly connected between the base 1 and the rotating disk 2. Adjacent shock-absorbing pads 16 are spaced at the same distance to absorb the vibration generated by the rotating disk 2 during rotation and lifting, thereby further improving the operational stability of the entire device.

[0020] In practical applications, the operating principle of this utility model's workstation is as follows: First, the shoe upper to be sewn is placed on the clamping device 301 of the workstation module 3, and the shoe upper is fixed by the clamping device 301. Then, the motor 501 is started, and the motor 501 drives the rotating disk 2 to rotate through the transmission gear 502, so that the workstation module 3 moves sequentially to a position aligned with the sewing machine head 4. When the workstation module 3 reaches the position aligned with the sewing machine head 4, the positioning pin 601 of the positioning mechanism 6 cooperates with the positioning hole 602 to achieve precise positioning of the rotating disk 2. Next, the lifting cylinder 901 of the lifting mechanism 9 drives the lifting rod 902 to rise, and through the linkage mechanism 10, drives the pressure plate 1101 of the pressing mechanism 11 to press down and tighten the shoe upper, ensuring that the shoe upper remains stable during the sewing process. The sewing machine head 4 begins sewing the shoe upper. After sewing is completed, the lifting cylinder 901 drives the lifting rod 902 to descend, the pressure plate 1101 releases the shoe upper, and the rotating disc 2 continues to rotate, moving the next workstation module 3 to a position aligned with the sewing machine head 4, repeating the above process. Throughout the entire operation, the buffer mechanism 7 and the shock-absorbing pad 16 effectively absorb the vibrations generated by the rotating disc 2, ensuring the smooth and reliable operation of the entire device.

[0021] The multi-station rotary automated workstation for shoe upper sewing provided by this utility model is highly efficient, flexible, and stable, and can significantly improve the production efficiency of shoe upper sewing and reduce manual intervention. Through the collaborative work of multiple workstation modules 3, continuous and automated shoe upper sewing is achieved, solving the problems of single workstation, low efficiency, and excessive manual intervention in existing shoe upper sewing equipment.

[0022] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
