Description

Technical Field

[0001] This utility model relates to the field of logistics sorting technology, and in particular to a lifting and shifting chain roller for logistics sorting. Background Technology

[0002] In logistics sorting systems, lifting transfer machines are an important type of equipment widely used to change the direction of goods transport, moving items from the forklift into or out of the main conveyor line. Their significant advantages include high load capacity, simple structure, and stable reliability. Especially in roller conveyors and chain conveyors, lifting transfer machines have become the preferred choice for situations where the sorting speed is less than 30 pieces / minute but the weight of a single item exceeds 2000 kg. These machines, controlled by a PLC programmable controller, enable smooth transfer of items between the main and auxiliary conveyor lines, avoiding collisions and squeezing, and ensuring efficient and safe logistics sorting.

[0003] However, the stability and reliability of some lifting and transferring machines may be affected during operation, especially when dealing with heavy or improperly placed items, leading to obstruction or jamming during lifting and lowering, which affects sorting efficiency. Secondly, some equipment lacks precision and cannot meet the requirements of some application scenarios with high positional accuracy. In addition, some equipment has a complex structure, making installation and disassembly inconvenient, which increases maintenance costs and difficulty. Utility Model Content

Detailed Implementation

[0019] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0020] Please see Figures 1 to 6 This utility model provides a lifting and shifting chain roller 13 for logistics sorting, including a C-shaped seat 1, two positioning members and a lifting frame 2. Multiple transmission shafts 3 are rotatably arranged above the lifting frame 2. Each transmission shaft 3 is provided with a first lifting sprocket 4. Cams 5 are provided at both ends of each transmission shaft 3. A lifting motor 6 is also provided above the lifting frame 2. A second lifting sprocket 7 is provided at the output end of the lifting motor 6. Each first lifting sprocket 4 and the second lifting sprocket 7 are connected by a lifting chain 8. The C-shaped seat 1 is set above the lifting frame 2 through the positioning members, and the multiple cams 5 abut against the bottom of the C-shaped seat 1.

[0021] In this embodiment, the design, through the lifting motor 6, the cam 5, and the sprocket transmission system, achieves smooth cyclic lifting of the lifting frame 2, enhancing the stability and reliability of the equipment. The four-point balanced lifting design ensures smooth lifting even when facing heavy or improperly placed items, avoiding obstruction or jamming, and improving sorting efficiency.

[0022] Furthermore, the positioning component includes a positioning seat 9 and two positioning plates 10. The positioning seat 9 is provided with a positioning rod 11. The positioning seat 9 is fixedly connected to the C-shaped seat 1 by bolts and is located on the outside of the C-shaped seat 1. The two positioning plates 10 are both fixedly connected to the lifting frame 2 by bolts and are located on the outside of the lifting frame 2. The positioning rod 11 extends between the two positioning plates 10.

[0023] In this embodiment, the positioning components are fixedly connected by bolts, which makes the structure stable and easy to disassemble, improving the ease of installation and maintenance of the equipment. The positioning rod 11 extends between the two positioning plates 10, ensuring the precise alignment between the C-shaped seat 1 and the lifting frame 2, further improving the stability and precision of the equipment.

[0024] Furthermore, the lifting and cutting chain roller 13 for logistics sorting also includes a plurality of support feet 12, which are respectively fixedly connected to the lifting frame 2 and located at the four bottom corners of the lifting frame 2.

[0025] In this embodiment, the design of the support foot 12 enhances the overall stability of the equipment, reduces vibration and shaking during operation, and improves the reliability and service life of the equipment.

[0026] Furthermore, a plurality of rollers 13 are rotatably disposed above the C-shaped seat 1, and the plurality of rollers 13 are arranged horizontally in sequence.

[0027] In this embodiment, the design of multiple horizontally arranged rollers 13 ensures that the items can be transported smoothly and continuously, reducing bumps and jams during transport and improving sorting efficiency and accuracy.

[0028] Furthermore, each of the rollers 13 is provided with a first conveying sprocket 14 at one end, a conveying motor 15 is provided on the inner side of the C-shaped seat 1, a second conveying sprocket 17 is provided at the output end of the conveying motor 15, and the first conveying sprocket 14 is connected to the second conveying sprocket 17 through a conveying chain 16.

[0029] In this embodiment, the conveyor motor 15 is connected to the first conveyor sprocket 14 of each roller 13 via the conveyor chain 16, realizing automated driving and synchronous rotation of the rollers 13. This design not only improves conveying efficiency but also ensures stability and consistency during the conveying process, meeting the requirements of high-precision sorting. Furthermore, using a variable frequency motor offers advantages such as adjustable speed, good energy efficiency, and smooth start-stop, further enhancing the equipment's performance and user experience.

[0030] In this invention, during operation, the lifting motor 6 starts, driving the first lifting sprocket 4 on each transmission shaft 3 to rotate via the second lifting sprocket 7 and lifting chain 8 at its output end. This causes the cams 5 at both ends of the transmission shaft 3 to rotate. Since multiple cams 5 are supported below the C-shaped seat 1, the rotation of the cams 5 drives the C-shaped seat 1 and the components mounted on it to perform four-point balanced lifting, achieving vertical lifting of the items. Simultaneously, the conveying motor 15 starts, driving the first conveying sprocket 14 at one end of each roller 13 to rotate via the second conveying sprocket 17 and conveying chain 16 at its output end. This causes multiple horizontally arranged rollers 13 to rotate synchronously, achieving horizontal conveying of the items. Throughout the process, the positioning component ensures precise alignment and stable connection between the C-shaped seat 1 and the lifting frame 2, while the support feet 12 enhance the overall stability of the equipment, reducing vibration and shaking during operation, and ensuring efficient, stable, and reliable logistics sorting.

[0031] In this utility model, a mechanical device is configured with dual motors to realize the operation of roller 13 and the cyclic lifting mechanism. The operation of the transmission shaft 3 and the cam 5 is relatively smooth and not prone to impact and vibration, which can meet some high precision requirements. The transmission efficiency is high. In addition, both the lifting motor 6 and the conveying motor 15 are variable frequency motors, which have the advantages of adjustable speed, good energy saving effect, and smooth start and stop. Moreover, the design of the lower space of the lifting bracket can be used to cooperate with forklifts for lifting operations.

[0032] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
