[0001] The utility model belongs to the technical field of warehousing, and particularly relates to a warehousing logistics handling system. Background Art

[0002] The statements herein only provide the background art related to the utility model, and do not necessarily constitute the prior art.

[0003] Warehousing is the storage and custody of goods and items through warehouses. Warehousing shelves are storage devices for storing goods.

[0004] In the application of warehousing shelves, some manufacturers set shelf robots on the shelves. The shelf robots usually set the loading platform on the columns, and the columns move along the shelves to pick up and place goods. However, in this solution, only one shelf robot can be set on the shelf. If more than two shelf robots are set, the columns of the two shelf robots will interfere with each other, resulting in relatively low efficiency of picking up and placing goods on the shelf. In addition, existing shelves generally cooperate with AGV cars at the bottom of the shelves to transport goods. During the operation of the AGV car, the shelf robot needs to wait for the AGV to reach the designated position, which also greatly limits the efficiency of picking up and placing goods. Content of the Utility Model

[0005] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a warehousing logistics handling system, which can pick up and place goods at different heights of the shelves in the same lane simultaneously, improving the operation efficiency of picking up and placing goods.

[0036] For the convenience of description, if the words "upper", "lower", "left", and "right" appear in the present utility model, they only indicate the same directions as the upper, lower, left, and right of the accompanying drawings themselves, and do not limit the structure. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be understood as a limitation of the present utility model.

[0037] Term explanation section: In the present utility model, if terms such as "installation", "connection", "connection", "fixation", etc. appear, they should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral body; it can be a mechanical connection, an electrical connection, a direct connection, or an indirect connection through an intermediate medium. It can be the internal connection of two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0038] In a typical embodiment of the present utility model, as Figure 1 shown, a warehousing and logistics handling system is proposed, which includes multiple rows of shelves 1 for storing 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.

[0039] An aisle 4 is formed between two adjacent rows of shelves 1, and the handling robot 2 is arranged in the aisle 4. The handling robot 2 is used to autonomously lift and lower within the set height range of the shelves 1 to handle target goods, where the target goods are goods to be warehoused or goods to be out of the warehouse. The set height ranges of the shelves corresponding to each handling robot 2 in each aisle 4 may overlap or not overlap. When there is no overlap, the handling robots 2 in the aisle 4 can simultaneously pick up and place goods at different heights; when there is overlap, the handling robots 2 in the aisle 4 can simultaneously pick up and place goods at the same height.

[0040] Among them, a horizontal slide rail 3 is arranged on the shelf 1. The horizontal slide rail 3 is horizontally arranged and can be walked on by the handling robot 2. That is, the handling robot 2 cooperates with the horizontal slide rail 3 and can move horizontally along the horizontal slide rail 3. Both sides of the handling robot 2 cooperate with the horizontal slide rails 3 of the adjacent two shelves 1.

[0041] Furthermore, multiple groups of horizontal slide rails 3 are arranged on the shelf 1 from top to bottom in the height direction, and the horizontal slide rails 3 are parallel to each other; multiple handling robots 2 are arranged between two adjacent rows of shelves 1, and the multiple handling robots 2 are respectively arranged on the horizontal slide rails 3 at different heights. Each handling robot 2 can move left and right along its own horizontal slide rail 3 to pick up and place the goods on the shelf 1. For example, in this embodiment, three handling robots 2 are arranged between two adjacent rows of shelves 1. The first handling robot 2 is arranged on the horizontal slide rail 3 at the top of the shelf 1, the second handling robot 2 is arranged on the horizontal slide rail 3 in the middle of the shelf 1, and the third handling robot 2 is arranged on the horizontal slide rail 3 at the lower part of the shelf 1.

[0042] Through the arrangement of multiple handling robots, the handling robots do not interfere with each other and can independently pick up and place goods. Therefore, goods can be picked up and placed at different heights of the shelf in the same lane at the same time, improving the operation efficiency of picking up and placing goods. In addition, when the frequency of inbound and outbound at a certain height is relatively high, the handling robot at other heights can be called to lower the loading platform to pick up and place the goods at this height, adapting to the change of the inbound and outbound frequency of goods at different heights in the same lane and improving the operation efficiency. As shown in Figure 4 , the frequency of inbound and outbound of the goods at the bottom of the shelf is relatively high, and the three handling robots can be called at the same time to pick up and place the goods at the bottom of the shelf to improve the efficiency.

[0043] Furthermore, the system is also provided with a hoist 5, and the hoist 5 is used to transfer the target goods with the handling robot.

[0044] Among them, the handling robot includes a mother vehicle 7 and a loading platform 8. The mother vehicle 7 cooperates with the horizontal slide rail 3, and the mother vehicle 7 can walk horizontally along the horizontal slide rail 3. A lifting drive mechanism is arranged on the mother vehicle 7. The lifting drive mechanism is connected to a lifting belt 9, and the movable end of the lifting belt 9 is connected to the loading platform 8 located below the mother vehicle 7 to drive the loading platform to lift. A lateral picking and placing device is arranged on the loading platform 8 for picking up and placing the goods on the shelf; the lateral picking and placing device can adopt a telescopic fork mechanism, and the telescopic fork mechanism can adopt the existing structure and will not be elaborated here. It should be noted that the lateral picking and placing device can also adopt other picking methods, such as clamping fork picking, suction cup picking, hook claw picking, etc., which are not limited here.

[0045] The mother vehicle 7 is provided with traveling wheel sets 10. The traveling wheel sets 10 are placed on the horizontal slide rails 3 and can travel along the horizontal slide rails 3, so as to drive the loading platform 8 to move horizontally through the lifting belt. At the same time, the lifting drive mechanism can drive the loading platform 8 to lift along the height direction of the shelf through the lifting belt 9, so that the loading platform 8 reaches the position of the target cargo space on the shelf.

[0046] In order to reduce the shaking of the loading platform during movement and ensure the smoothness of cargo transportation, along the direction from top to bottom, the lifting belt 9 is inclined towards the central position direction of the loading platform 8, and the lifting belt 9 forms a set angle with the vertical direction.

[0047] The lifting drive mechanism can drive the lifting belt 9 to retract and release it; the lifting drive mechanism includes a plurality of drive components, and each lifting belt is correspondingly connected to a drive component. In this embodiment, four lifting belts 9 are provided, so four drive components are installed on the mother vehicle 7. Since the length of the part of the lifting belt between the mother vehicle 7 and the loading platform 8 will change after long-term use, resulting in the loading platform being unable to maintain horizontal, therefore, each lifting belt corresponds to a drive component, and each lifting belt can be independently retracted and released, and the lifting belt can be adjusted through the drive component to make the loading platform maintain a horizontal state.

[0048] In an alternative embodiment, the drive component can adopt a hoisting mechanism.

[0049] In order to ensure the stability of the loading platform 8 during the process of loading and unloading goods, at least one telescopic push rod 11 is provided on both sides of the loading platform 8 parallel to the traveling direction. The telescopic push rod 11 can extend out and abut against the surface of the shelf on the side of the loading platform after the loading platform runs in place to stabilize the loading platform.

[0050] In one alternative embodiment, as Figure 5 shown, the elevator 5 is arranged at the end position of the aisle 4 formed between two adjacent shelves 1 for transferring goods with the handling robot at the end of the shelf. In this embodiment, a split platform can be slidably arranged at the bottom of the loading platform 8, and the split platform is driven by a drive mechanism to open and close. 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 drive mechanism can adopt a hydraulic telescopic mechanism, a pneumatic telescopic mechanism, a synchronous belt transmission mechanism, etc., which are not limited here.

[0051] In other alternative embodiments, as Figure 1 shown, a transition platform 6 is arranged at the end of the shelf 1, and the elevator 5 is arranged on one side of the transition platform 6. For example, the elevator 5 can be arranged at one end far from the shelf 1. The transition platform 6 is located between the shelf 1 and the elevator 5, and the handling robot 2 and the elevator 5 transfer the target goods through the transition platform 6.

[0052] The handling robot 2 takes out the goods on the shelf 1 and places them on the transfer platform 6, and then the goods are transferred to the conveying equipment by the elevator 5 for further transportation. The conveying equipment can adopt existing assembly lines, conveyors, etc., which are not limited here.

[0053] The transfer platform 6 can be in the form of a multi-layer platform. After the handling robot 2 takes out the goods, it places them on each layer of the transfer platform 6, and the elevator 5 moves up and down to take out the goods placed on each layer of the transfer platform 6 and transfer them to the conveying equipment.

[0054] It should be noted that the transfer platform 6 can also be arranged in the middle of the shelf 1.

[0055] In this implementation, a power conveying mechanism can be arranged on the transfer platform 6. The power conveying mechanism of the transfer platform 6 can adopt power rollers, conveyor belts, etc.

[0056] In other alternative implementations, a picking mechanism is arranged on the loading platform of the elevator 5. The picking mechanism on the loading platform of the elevator 5 can adopt conveying mechanisms such as power rollers and conveyor belts, or can also adopt existing telescopic forklifts for picking, suction cups for picking, etc. It should be noted that the power conveying mechanism of the transfer platform 6 and the picking mechanism on the loading platform of the elevator 5 can be set alternatively, or can also be set simultaneously.

[0057] The working principle of this handling system is as follows:

[0058] The walking wheel set 10 of the handling robot 2 cooperates with the horizontal slide rail 3 arranged on the shelf 1 and moves horizontally along the horizontal slide rail;

[0059] The lifting drive mechanism of the handling robot 2 drives the loading platform 8 to lift and lower through the lifting belt 9 to reach the target cargo position on the shelf;

[0060] When receiving an outbound task, the handling robot 2 first walks along the horizontal slide rail 3 to the position above the target cargo position, and then the loading platform 8 is driven by the lifting belt 9 to descend to the target cargo position. The descent of the loading platform can be synchronized with the movement of the walking wheel set. The telescopic push rod 11 extends and presses against the side of the shelf tightly. The side loading and unloading device of the loading platform 8 picks up the goods. The telescopic push rod 11 retracts. The handling robot 2 drives the loading platform to the elevator 5 or the transfer platform 6. The side loading and unloading device of the loading platform discharges the goods to the elevator 5 or the transfer platform 6. Then the elevator directly transfers the goods to the conveying equipment, or the elevator takes out the goods on the transfer platform and transfers them to the conveying equipment to complete the outbound. On the contrary, it is the inbound process.

[0061] Multiple handling robots in the roadway can simultaneously pick up and place goods at different heights; or, when the frequency of picking up and placing goods at a certain height on the shelf is relatively high, multiple handling robots 2 are simultaneously moved to that height to pick up and place goods to improve the operation efficiency.

[0062] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, various modifications and variations can be made to the present utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
