[0018] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0019] In order to solve the technical problems in the prior art that manpower is still needed to ensure accurate operation of loading and unloading operations and the degree of automation is not high, the present invention provides an automatic loading and unloading logistics equipment for carton-packaged groceries and bagged groceries, which can realize automatic loading and unloading.

[0020] It should be noted that the automatic loading and unloading logistics equipment for carton-piece groceries and bagged groceries described in the present invention is used for but not limited to loading of cargo in containers. For the convenience of explanation, in the present invention, only the application of the automatic loading and unloading logistics equipment for carton-piece groceries and bagged groceries to loading of cargo in containers is taken as an example for explanation, and the principle of applying the automatic loading and unloading logistics equipment for carton-piece groceries and bagged groceries to loading of other types of cargo is substantially the same as that applied to loading of cargo in containers, which will not be elaborated here one by one.

[0021] See also Figure 1 , Figure 1 The schematic diagram of the structure of the automatic loading and unloading logistics equipment for carton-piece groceries and bagged groceries in one embodiment of the present invention comprises a first conveying unit 1, a second conveying unit 2, a third conveying unit 3 and a gripping mechanism 4. The first conveying unit 1 has a longitudinal degree of freedom in the conveying direction, and is used to extend and retract its length along the conveying direction. It has a telescopic function, so that the equipment has a degree of freedom in the depth direction of the container, ensuring that the goods are placed in the longitudinal direction of the container. In order to ensure that this section of the conveyor belt can be loaded onto an AGV or a CNC carrier to achieve good mobility and can be moved to other sites for operation as needed, a common three-section telescopic conveyor belt can be used, such as Figure 2 and Figure 3 As shown, it is an existing mature three-section conveyor belt, for example, a three-section telescopic conveyor belt of model HRSSJ-8; the second conveying part 2 is connected to the tail end of the first conveying part 1 through a rotating mechanism 201, which is used to adjust the conveying lateral position of the second conveying part 2 by rotating left and right, and adjust the arrangement of the goods in the lateral direction, and the second conveying part 2 has a pitch freedom with the rear end as the axis, which is used to adjust the conveying height position and adjust the stacking of the goods in the vertical direction. With the cooperation of left and right rotation and up and down pitching, the goods can be stacked horizontally and vertically in a cubic distributed manner and placed in a container; the third conveying part 3 is connected to the tail end of the second conveying part 2 through a rotating correction mechanism 202, which is used to adjust the delivery angle to a horizontal angle so as to deliver the goods straight into the container; the grabbing mechanism 4 is arranged on the third conveying part 3, which is used to grab the goods to the third conveying part 3, and is mainly used for unloading, so that the automatic loading and unloading logistics equipment not only has the function of filling the goods into the container, but also has the function of unloading the goods in the container. One device can be used to load and unload goods from containers, and container carton pieces and bagged pieces of groceries can be loaded and unloaded automatically and accurately, which improves work efficiency, uniformity of operations and stability of operation time, and reduces time and financial costs and the risk of personal injury.

[0022] In one embodiment, see Figure 1The first conveying part 1 includes three sections of telescopic conveyor belts 11 and a movable support 12, which is arranged at the bottom of the three sections of telescopic conveyor belts 11 and is used for moving the position of the first conveying part 1. The movable support 12 is provided with rows of moving wheels, which play the role of bottom support and movement, and is used to dock with the cargo transfer equipment required to transport the cargo from the transfer equipment to the container, or to transport the cargo unloaded from the container to the transfer equipment.

[0023] In one embodiment, see Figure 1 , Figure 4 and Figure 5 The second conveying part 2 includes a conveyor belt body 21 and a hydraulic lifting mechanism 22 with a universal wheel 203 at the bottom. The two ends of the conveyor belt body 21 are respectively connected to the first conveying part 1 and the second conveying part 2. The movable end of the hydraulic lifting mechanism 22 is movably connected to the conveyor belt body 21, so that the second section of the conveyor belt has a pitch freedom with the rear end as the axis, ensuring that the goods are placed in the direction of the container height, and is used to telescopically drive the conveyor belt body 21 to adjust the pitch angle with the rear end as the axis, and the universal wheel 203 can automatically compensate for the displacement difference between the front and rear due to the internal force when changing the pitch angle.

[0024] In this embodiment, please refer to Figure 6 and Figure 7 The rotating mechanism 201 can use an arc motor. The guide rail of the arc motor is loaded onto the chassis of the first conveying part 1, and the slider of the arc motor is fixed to the conveyor belt body 21. When the motor is started, the slider moves on the arc motor guide rail, and the second section of the conveyor belt realizes the function of left and right rotation.

[0025] It can be understood that when the arc motor is started, the driving slider slides along the guide rail. When the guide rail is in an arc shape, a rotational driving effect can be formed. In addition, the rotating mechanism 201 can also use other devices with rotation angle adjustment function, such as a rotating motor.

[0026] For further information, see Fig. 9 The rotation correction mechanism 202 can use a rotating motor, and during the rotation process of the second conveying part 2, the third conveying part 3 is automatically adjusted to a horizontal angle through numerical control to deliver the goods straight into the container.

[0027] In this embodiment, in order to fold and store the second conveying unit 2, please refer to Fig.13 and Fig.14The second conveying part 2 also includes a lifting and transverse moving mechanism 23, which is installed on the first conveying part 1, and its movable end is connected to the conveyor belt body 21, and is used to lower the conveyor belt body 21 and transversely move it to the bottom of the first conveying part 1, wherein the lifting and transverse moving mechanism 23 includes two slider guide linear motor modules arranged on the outer side of the rear end of the conveyor belt body 21, providing three degrees of freedom of rotation, up and down, and front and back, so that the conveyor belt body 21 can be stored in the gap of the movable support 12, so as to make the equipment lighter.

[0028] It can be understood that the two slider guide linear motor modules on the lifting and transverse movement mechanism 23 are two slider guide linear motor modules that cross each other, one provides lifting in the vertical direction, and the other provides movement along the length direction of the conveyor belt body 21.

[0029] Furthermore, the universal wheel 203 is connected to the bottom of the hydraulic lifting mechanism 22 via a stepping motor for folding and storage, and is folded up via a small stepping motor for storage of the second conveying part 2 .

[0030] In one embodiment, see Figure 8 and Fig. 9 A guide mechanism 5 is provided at the joints between the second conveying part 2 and the first conveying part 1 and the third conveying part 3, which is used to push the goods to an angle parallel to the conveyor belt, so that the goods can be adjusted to an angle parallel to the conveyor belt under the action of external force when entering the joints of each conveyor belt at different angles.

[0031] Specifically, the guide mechanism 5 includes a pair of drive motors 51, and a pair of push plates 52 respectively arranged on the output shafts of the pair of drive motors 51. The pair of drive motors 51 are arranged on both sides of the joint between the second conveying part 2 and the first conveying part 1 or the third conveying part 3, and are used to drive the push plates 52 to push the goods to adjust the position. The deflection position of the two push plates 52 is adjusted by the drive motor 51 to form a guiding direction, so that the goods are adjusted to an angle parallel to the conveyor belt.

[0032] In one embodiment, see Fig.10 , Fig.11 and Fig.12The third conveying part 3 includes a transition conveyor belt 31 and a shipping conveyor belt 32, and the two ends of the transition conveyor belt 31 are respectively connected to the second conveying part 2 and the shipping conveyor belt 32, wherein the upper surface of the transition conveyor belt 31 is horizontal, and the upper surface of the shipping conveyor belt 32 is inclined downward. In addition, a static baffle 301 and a movable baffle 302 are respectively provided on both sides of the shipping conveyor belt 32, and the movable baffle 302 is installed on the shipping conveyor belt 32 through a telescopic mechanism. The telescopic mechanism is used to push the movable baffle 302 to approach or move away from the static baffle 301. After the goods enter, the movable baffle 302 is translated toward the static baffle 301 at the other end, so that cubic goods such as cartons and sacks are in contact with the static end both on the conveyor belt and in the process of leaving the conveyor belt, so as to ensure the accuracy of goods stacking.

[0033] In this embodiment, the length of the stationary baffle 301 is greater than that of the movable baffle 302. The stationary baffle 301 has a positioning function, while the movable baffle 302 mainly moves on the surface of the conveyor belt to avoid interference with the stacked goods during movement.

[0034] In one embodiment, see Fig.11 and Fig.12 The grabbing mechanism 4 includes a guide rod mechanism 41 with two degrees of freedom, up and down and front and back. The guide rod mechanism 41 is installed on the third conveying part 3. A rotating motor 42 is provided at the movable end of the guide rod mechanism 41. A cross bar 43 is provided on the output shaft of the rotating motor 42. A row of pneumatic suction cups 44 are provided on the cross bar 43. The goods can be loaded and unloaded by adsorption and lifting.

[0035] For details, please refer to Fig.15 , Fig.16 and Fig.17 During loading and unloading, first stretch and adsorb, then shrink and release the adsorption, place the upper layer of goods on the third conveying part 3, and align the next layer under the height lifting of the second conveying part 2, and repeat the above process to carry out multi-layer unloading. Similarly, under the lateral swing of the second conveying part 2, the vertical column of goods on the side can be unloaded.

[0036] It can be understood that the guide rod mechanism 41 can be composed of a vertically arranged hydraulic push rod and a horizontally arranged hydraulic push rod.

[0037] In order to better understand the present invention, the following Figures 1 to 17The technical solution of the present invention is described in detail: during the loading process, the goods are transported from the three-section telescopic conveyor belt 11 to the conveyor belt body 21, then moved from the conveyor belt body 21 to the transition conveyor belt 31, and finally unloaded from the shipping conveyor belt 32 into the container 6. During this process, the height position of the loading is adjusted by the hydraulic lifting mechanism 22, the lateral position of the loading is adjusted by the rotating mechanism 201, and the parallelism of the goods with the conveying direction is adjusted during the conveying process by the guide mechanism 5. Finally, the specific orientation and position of the goods when unloading are adjusted by opening and closing the static baffle 301 and the movable baffle 302; during the unloading process, the goods are adsorbed by the pneumatic suction cup 44, and moved to the shipping conveyor belt 32 under the extension and lifting of the guide rod mechanism 41, and unloaded from the container 6 under the direction of the shipping conveyor belt 32, the transition conveyor belt 31, the conveyor belt body 21 and the three-section telescopic conveyor belt 11.

[0038] Compared with the prior art, the embodiments of the present invention have at least the following effects: (1) From the time the equipment arrives at the work site to the completion of the loading and unloading operation, no human resources are required throughout the entire process, achieving fully automatic and accurate loading and unloading of container carton breakbulks and bagged breakbulks, improving work efficiency, work uniformity, and the stability of work duration, reducing time and financial costs and the risk of personal injury, and providing a certain foundation for the digital transformation of ports.

[0039] (2) The unification of loading and unloading equipment has been achieved, which has optimized resource scheduling to a certain extent and improved the efficiency of port operations. Compared with using two devices to complete the automatic loading and unloading operations separately, the port's shipping and unloading operations use the same device to complete the automatic loading and unloading operations. The former is significantly better than the latter in terms of indicators such as cost and resource scheduling.

[0040] (3) There are many types and sizes of breakbulk cargo, and the ability to handle multiple types and sizes of automatic loading and unloading equipment can reduce the number of specialized equipment that needs to be purchased and maintained, which can significantly reduce capital expenditures and operating costs in the long run. It reduces equipment idle time, improves asset utilization, and brings higher economic benefits to port operations. Universal equipment can quickly adjust the operating mode to ensure the continuity and smoothness of loading and unloading operations, avoid delays caused by waiting for specific equipment, and improve the overall operating efficiency of the port.

[0041] (4) Compared with equipment that needs to be moved frequently, the stability and durability of this equipment provide reliable operation support for unmanned terminals, reduce the time loss and precision error caused by frequent disassembly and assembly, and ensure the continuity and high efficiency of the operation process. For non-fixed point loading and unloading needs, this equipment can flexibly shuttle between different operation areas without taking up additional time of container transport equipment such as container trucks, reducing the pressure of configuring the road network, achieving full-scenario coverage of container handling capabilities, and greatly enhancing operational flexibility and adaptability.

[0042] The specific implementation of the present invention described above does not constitute a limitation on the protection scope of the present invention. Any other corresponding changes and modifications made based on the technical concept of the present invention should be included in the protection scope of the claims of the present invention.
