[0046] As shown in FIG. 1, the embodiment of the present disclosure provides a warehouse logistics handling system, which comprises a plurality of rows of shelves 1, the shelves 1 are configured to store goods; a handling robot 2 is arranged between two adjacent rows of shelves 1, and the handling robot 2 can move horizontally on the shelves 1.

[0047] The aisles 4 are formed between the adjacent two rows of shelves 1, and the carrying robots 2 are arranged in the aisles 4. The carrying robots 2 are configured to autonomously ascend and descend within a set height range of the shelves 1 to carry target goods, wherein the target goods are goods to be stored or goods to be taken out. The corresponding shelf set height ranges of each carrying robot 2 in each aisle 4 have or do not have intersection. When there is no intersection, the carrying robots 2 in the aisle 4 can simultaneously take and place goods at different heights; when there is intersection, the carrying robots 2 in the aisle 4 can simultaneously take and place goods at the same height.

[0048] The shelves 1 are provided with horizontal rails 3, and the horizontal rails 3 are horizontally arranged. The carrying robots 2 can walk on the horizontal rails 3, that is, the carrying robots 2 cooperate with the horizontal rails 3 and can move horizontally along the horizontal rails 3. The two sides of the carrying robots 2 cooperate with the horizontal rails 3 of the adjacent two shelves 1.

[0049] Optionally, a plurality of groups of horizontal rails 3 are arranged on the shelves 1 from top to bottom in the height direction, and the horizontal rails 3 are parallel to each other. A plurality of carrying robots 2 are arranged between the adjacent two rows of shelves 1, and the plurality of carrying robots 2 are arranged on the horizontal rails 3 at different heights, respectively. Each carrying robot 2 can move left and right along the corresponding horizontal rail 3 to take and place goods on the shelves 1. In this embodiment, three carrying robots 2 are arranged between the adjacent two rows of shelves 1, wherein the first carrying robot 2 is arranged on the horizontal rail 3 at the top of the shelves 1, the second carrying robot 2 is arranged on the horizontal rail 3 at the middle of the shelves 1, and the third carrying robot 2 is arranged on the horizontal rail 3 at the bottom of the shelves 1.

[0050] Through the arrangement of the plurality of carrying robots 2, the carrying robots 2 do not interfere with each other and can independently take and place goods. Therefore, the different heights of the shelves 1 in the same aisle 4 can be taken and placed at the same time, and the work efficiency of taking and placing goods is improved. In addition, when the frequency of storing and taking out goods at a certain height is high, the carrying robots 2 at other heights can be called to lower the loading platform 8 to take and place goods at the height, adapt to the change of the frequency of storing and taking out goods at different heights in the same aisle 4, and improve the work efficiency. As shown in FIG. 4, the frequency of storing and taking out goods at the bottom of the shelves 1 is high, and the three carrying robots 2 can be simultaneously called to take and place goods at the bottom of the shelves 1 to improve the efficiency.

[0051] Optionally, the system further comprises a lifting machine 5 configured to transfer the target goods with the carrying robots 2.

[0052] The carrying robot comprises a mother vehicle 7 and a loading platform 8. The mother vehicle 7 is matched with the horizontal slide rail 3 and can horizontally walk along the horizontal slide rail 3. The mother vehicle 7 is provided with a lifting driving mechanism connected with the lifting belt 9. The movable end of the lifting belt 9 is connected with the loading platform 8 below the mother vehicle 7 to drive the lifting of the loading platform 8. The loading platform 8 is provided with a lateral goods taking and placing device for taking and placing goods on the goods shelf. The lateral goods taking and placing device can adopt a telescopic fork mechanism. The telescopic fork mechanism can adopt an existing structure and will not be described here. It should be noted that the lateral goods taking and placing device can also adopt other taking methods, such as a clamping fork taking method, a suction cup taking method, a hook claw taking method, etc. and will not be limited here.

[0053] The mother vehicle 7 is provided with a walking wheel set 10 placed on the horizontal slide rail 3 and can walk along the horizontal slide rail 3 to drive the horizontal movement of the loading platform 8 through the lifting belt 9. Meanwhile, the lifting driving mechanism can drive the lifting of the loading platform 8 along the height direction of the goods shelf 1 through the lifting belt 9 to make the loading platform 8 reach the position of the target goods position on the goods shelf 1.

[0054] In order to reduce the shaking of the loading platform 8 during the movement and ensure the stability of the goods transportation, the lifting belt 9 is inclined towards the center position of the loading platform 8 in the direction from top to bottom and forms a set angle with the vertical direction.

[0055] The lifting driving mechanism can drive the lifting belt 9 to be retracted and released. The lifting driving mechanism comprises a plurality of driving assemblies. Each lifting belt 9 is connected with a driving assembly. In this embodiment, four lifting belts 9 are arranged, so four driving assemblies are installed on the mother vehicle 7. Since the length of the part between the mother vehicle 7 and the loading platform 8 of the lifting belt changes after long-time use, the loading platform 8 cannot be kept horizontal. Therefore, each lifting belt 9 is connected with a driving assembly. Each lifting belt 9 can be independently retracted and released. The lifting belt 9 can be adjusted by the driving assembly to keep the loading platform 8 in a horizontal state.

[0056] Optionally, the driving assembly can adopt a winch mechanism.

[0057] In order to ensure the stability of the loading platform 8 during the taking and placing of goods, at least one telescopic push rod 11 is arranged on both sides of the loading platform 8 parallel to the walking direction. The telescopic push rod 11 can be extended to abut against the surface of the goods shelf 1 beside the loading platform 8 after the loading platform 8 is moved to the position to stabilize the loading platform 8.

[0058] Optionally, as shown in FIG. 5, the lifting machine 5 is arranged at the end of the aisle 4 formed between two adjacent shelves 1 to transfer goods with the transfer robot 2 at the end of the shelf 1. In this embodiment, a split platform can be arranged at the bottom of the loading platform 8 and driven to open and close by a driving mechanism. For example, a split platform that can open and close left and right is arranged at the bottom of the loading platform 8, and the driving mechanism can be a hydraulic telescopic mechanism, a pneumatic telescopic mechanism, a synchronous belt transmission mechanism, etc., which is not limited here.

[0059] Optionally, as shown in FIG. 1, a transition platform 6 is arranged at the end of the shelf 1, and the lifting machine 5 is arranged at one side of the transition platform 6, for example, the lifting machine 5 can be arranged at the end away from the shelf 1. The transition platform 6 is located between the shelf 1 and the lifting machine 5, and the transfer robot 2 and the lifting machine 5 transfer target goods through the transition platform 6.

[0060] The transfer robot 2 takes out the goods on the shelf 1 and places them on the transition platform 6, and then the goods are transferred to the conveying device by the lifting machine 5 for further transportation. The conveying device can be an existing assembly line, conveyor, etc., which is not limited here.

[0061] The transition platform 6 can be a multi-layer platform, and the transfer robot 2 places the goods on each layer of the transition platform 6 after taking them out, and the lifting machine 5 moves up and down to take out the goods placed on each layer of the transition platform 6 and transfer them to the conveying device.

[0062] It should be noted that the transition platform 6 can also be arranged at the middle of the shelf 1.

[0063] In this embodiment, a power conveying mechanism can be arranged on the transition platform 6. The power conveying mechanism of the transition platform 6 can be a power roller, a conveyor belt, etc.

[0064] Optionally, a goods taking mechanism is arranged on the loading platform of the lifting machine 5. The goods taking mechanism of the loading platform of the lifting machine 5 can be a power roller, a conveyor belt, etc., or can be an existing telescopic fork taking mechanism, a suction cup taking mechanism, etc. It should be noted that the power conveying mechanism of the transition platform 6 and the goods taking mechanism of the loading platform of the lifting machine 5 can be arranged alternatively or simultaneously.

[0065] The working principle of the warehouse logistics transfer system provided by the embodiments of the present disclosure is as follows:

[0066] The walking wheel set 10 of the transfer robot 2 cooperates with the horizontal slide rail 3 arranged on the shelf 1 and moves horizontally along the horizontal slide rail;

[0067] The lifting driving mechanism of the transfer robot 2 drives the loading platform 8 to lift through the lifting belt 9 to reach the target goods location of the shelf;

[0068] When receiving the outbound task, the carrying robot 2 first walks along the horizontal slide rail 3 to above the target storage location, and then the loading platform 8 is lowered to the target storage location by the lifting belt 9. The lowering of the loading platform 8 can be simultaneously performed with the movement of the walking wheel set. The telescopic push rod 11 is extended to tightly abut against the side of the shelf. The side loading and unloading device of the loading platform 8 loads the goods. The telescopic push rod 11 is retracted. The carrying robot 2 drives the loading platform 8 to the elevator 5 or the transition platform 6. The side loading and unloading device of the loading platform 8 loads the goods to the elevator 5 or the transition platform 6. Then, the elevator 5 directly transfers the goods to the conveying device, or the elevator 5 takes out the goods from the transition platform 6 and transfers the goods to the conveying device, thereby completing the outbound process. Conversely, it is the inbound process.

[0069] The plurality of carrying robots 2 in the aisle 4 can simultaneously load and unload goods at different heights. Alternatively, when the loading and unloading frequency at a certain height of the shelf 1 is high, the plurality of carrying robots 2 can simultaneously move to the height to load and unload goods, thereby improving the operation efficiency.

[0070] The above only describes specific embodiments of the present disclosure and is not used to limit the present disclosure. For those skilled in the art, the present disclosure can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present disclosure shall be included in the protection scope of the present disclosure. Industrial applicability

[0071] In summary, the embodiments of the present disclosure provide a warehouse logistics carrying system. The plurality of carrying robots are arranged, and the carrying robots do not interfere with each other and can independently load and unload goods. Therefore, the different heights of the shelves in the same aisle can be simultaneously loaded and unloaded, thereby improving the operation efficiency of loading and unloading.
