[0002] In the modern warehousing and logistics field, automated warehousing robots have become key equipment for improving warehousing efficiency. The fork structure, as the core component for automated storage and retrieval of goods by warehousing robots, directly impacts the operational efficiency of the entire warehousing system. Existing warehousing robot fork structures have significant limitations: most forks can only perform storage and retrieval operations in a single direction, exhibiting extremely poor flexibility and failing to adapt to complex warehousing scenarios. Only a small number of bidirectional forks can complete storage and retrieval on both sides of racks, but this is limited to a "retrieve goods from rack A and store them on rack A, retrieve goods from rack B and store them on rack B" pattern, unable to achieve cross-rack operations such as retrieving goods from rack A and directly storing them on rack B. These limitations severely restrict the operational range and efficiency of warehousing robots, increase the complexity and time costs of warehousing operations, and fail to meet the demands of modern warehousing for efficient and flexible storage and retrieval. Utility Model Content
[0003] This application provides a bidirectional storage and retrieval device, which solves the problem that although the bidirectional forks of the existing warehouse robot can complete the storage and retrieval of both sides of the rack, they are limited to the mode of "retrieving goods from rack A and storing them on rack A, retrieving goods from rack B and storing them on rack B". It cannot realize cross-rack operation of retrieving goods from rack A and storing them directly on rack B. This increases the complexity and time cost of the warehousing operation process, and at the same time makes it difficult to meet the technical problem of modern warehousing's demand for efficient and flexible storage and retrieval.
[0004] The technical solutions adopted in the embodiments of this application are as follows.
[0005] A bidirectional access device includes a material frame, a feeding platform for supporting the material frame, a claw module for gripping and pushing the material frame, a transmission component for driving the material frame to move on the feeding platform, and a guide plate for guiding the material frame to travel in the center of the feeding platform; the claw module is disposed on the feeding platform; two sets of the transmission components are disposed on the feeding platform, and the two sets of transmission components are symmetrically arranged with respect to the claw module; the guide plates are respectively disposed on both sides of the feeding platform, and the two sets of guide plates are respectively placed corresponding to the two sets of transmission components.
[0006] As a further improvement to the above technical solution: A further technical solution is as follows: the hook module includes a hook, a servo motor, a bracket, a linear slider, a linear slide rail, a first drive device, a gear, and a rack; the hook is rotatably connected to the bracket; the servo motor is mounted on the bracket; the hook is connected to the output end of the servo motor; the servo motor can drive the hook to rotate 90 degrees to switch the hook to an upright or flat state; the bracket is set on the linear slider; the linear slider is slidably connected to the linear slide rail; the first drive device is mounted on the bracket; the output shaft of the first drive device is connected to the gear; the gear meshes with the rack; the rack is set on the feeding platform; by driving the gear to roll on the rack through the output shaft of the first drive device, the hook can be moved in an upright or flat state.
[0007] A further technical solution is as follows: the transmission component includes a conveyor belt, pulleys, a support frame, and a second drive device; the support frame is disposed on the feeding platform; the pulleys are rotatably connected to both ends of the support frame; the conveyor belt is wound around two sets of pulleys; the second drive device is installed on one side of the support frame, and the output shaft of the second drive device is drivenly connected to one set of pulleys.
[0008] A further technical solution is as follows: handles are installed on both sides of the lower part of the material frame, and the handles are used to cooperate with the hooks of the hook module to grasp.
[0009] A further technical solution is that both the first driving device and the second driving device are electric motors.
[0010] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages: 1. The device utilizes a combination of material frames, a feeding platform, a claw module, a transmission assembly, and a guide plate. Through the coordinated operation of the claw module and the transmission assembly, cross-shelf operations—retrieving goods from the shelf and placing them directly back on it—are achieved, significantly enhancing the flexibility of warehousing operations. The claws in the claw module can rotate 90 degrees and move linearly along a linear guide rail. Combined with the synchronous belt drive of the transmission assembly, the gripping, moving, and placing of the material frames is smoother and more efficient, reducing unnecessary intermediate steps, shortening storage and retrieval time, and improving overall warehousing efficiency. The handles on both sides of the material frames provide reliable gripping points for the claws, the guide plate ensures that the material frames always move along the central path on the feeding platform, and the synchronous belt drive structure of the conveyor belt and pulleys ensures transmission accuracy. All of these factors contribute to a more stable and reliable storage and retrieval operation, reducing the risk of material frames tipping over or shifting. The components are compactly arranged, and the retractable design of the hook module saves space. The symmetrically arranged transmission components and guide plates ensure the balance of the device during operation. The overall structure is simple and easy to maintain, reducing the equipment's failure rate and maintenance costs. Based on the modification of standard material frames, the device can be adapted simply by adding handles, without the need for large-scale replacement of existing warehouse material frames. This facilitates its widespread application in existing warehousing systems and adapts to the needs of different types of warehousing scenarios. Attached Figure Description

[0015] This application provides a bidirectional storage and retrieval device, which solves the problem that although the bidirectional forks of the existing warehouse robot can complete the storage and retrieval of both sides of the rack, they are limited to the mode of "retrieving goods from rack A and storing them on rack A, retrieving goods from rack B and storing them on rack B". It cannot realize cross-rack operation of retrieving goods from rack A and storing them directly on rack B. This increases the complexity and time cost of the warehousing operation process, and at the same time makes it difficult to meet the technical problem of modern warehousing's demand for efficient and flexible storage and retrieval.
[0016] The technical solution in this application embodiment is to solve the above problems, and the overall idea is as follows: To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.
[0017] A bidirectional access device, such as Figure 1 , Figure 2 and Figure 3 As shown, the device includes a material frame 1, a feeding platform 2 for supporting the material frame 1, a claw module 3 for gripping and pushing the material frame 1, a transmission component 4 for driving the material frame 1 to move on the feeding platform 2, and a guide plate 5 for guiding the material frame 1 to travel in the center of the feeding platform 2. The claw module 3 is disposed on the feeding platform 2. Two sets of transmission components 4 are disposed on the feeding platform 2, and the two sets of transmission components 4 are symmetrically arranged with respect to the claw module 3. Guide plates 5 are disposed on both sides of the feeding platform 2, and the two sets of guide plates 5 are respectively placed corresponding to the two sets of transmission components 4.
[0018] The hook module 3 includes a hook 31, a servo motor 32, a bracket 33, a linear slider 34, a linear slide rail 35, a first drive device 36, a gear 37, and a rack 38. The hook 31 is rotatably connected to the bracket 33. The servo motor 32 is mounted on the bracket 33. The hook 31 is connected to the output end of the servo motor 32. The servo motor 32 can drive the hook 31 to rotate 90 degrees to switch the hook 31 between an upright or flat position. The bracket 33 is set on the linear slider 34. The linear slider 34 is slidably connected to the linear slide rail 35. The first drive device 36 is mounted on the bracket 33. The output shaft of the first drive device 36 is connected to the gear 37. The gear 37 meshes with the rack 38. The rack 38 is set on the feeding platform 2. The output shaft of the first drive device 36 drives the gear 37 to roll on the rack 38, which can move the hook 31 in an upright or flat position.
[0019] The transmission assembly 4 includes a conveyor belt 41, pulleys 42, a support frame 43, and a second drive device 44. The support frame 43 is mounted on the feeding platform 2. Both ends of the support frame 43 are rotatably connected to pulleys 42. The conveyor belt 41 is wound around two sets of pulleys 42. The second drive device 44 is mounted on one side of the support frame 43, and the output shaft of the second drive device 44 is drivenly connected to one set of pulleys 42.
[0020] Handles 11 are installed on both sides of the lower part of the material frame 1. The handles 11 are used to cooperate with the hooks 31 of the hook module 3 for gripping.
[0021] Both the first drive unit 36 and the second drive unit 44 are electric motors.
[0022] The material frame 1 is modified from a standard material frame, and handles 11 are installed on both sides of its lower part. The handles 11 are used to cooperate with the hooks 31 of the hook module 3 for gripping, providing a reliable force point for the operation of the hooks. The feeding platform 2 serves as the supporting foundation for the entire device, used to place the material frame 1 and install other components. The hook 31 is rotatably connected to the bracket 33. A servo motor 32 is mounted on the bracket 33, and the hook 31 is connected to the output end of the servo motor 32. The servo motor 32 can drive the hook 31 to rotate 90 degrees, thus switching the hook 31 between an upright and a horizontal position. The bracket 33 is mounted on a linear slider 34, which is slidably connected to a linear guide rail 35, ensuring the directional movement of the bracket 33 and the entire hook module 3. A first drive device 36 is mounted on the bracket 33, and its output shaft is connected to a gear 37. The gear 37 meshes with a rack 38, which is mounted on the feeding platform 2. The output shaft of the first drive device 36 drives the gear 37 to roll on the rack 38, enabling the hook 31 to move in either an upright or horizontal position. The first drive device 36 is a motor. The guide plate 5 is used to guide the material frame 1 to move in the center of the feeding platform 2. The two sides of the feeding platform 2 are respectively provided with guide plates 5, and the two sets of guide plates 5 are respectively placed with the two sets of transmission components 4 to ensure that the material frame will not deviate from the preset path during the movement. Operating procedures Taking the process of picking up material from shelf A and delivering it to shelf B as an example, the operation flow of this device is as follows: The feeding platform 2 is transported by the aisle trolley to the fixed point of the shelf A, ready to load and pick up the target material frame 1.
[0023] The hook 31 of the hook module 3 is in a flat position. Driven by the first drive device 36, the entire hook module 3 moves along the linear slide rail 35 to the edge of the platform through the meshing motion of the gear 37 and the rack 38. The servo motor 32 drives the hook 31 to rotate to an upright position, so that it passes through the handle 11 of the material frame 1, completing the gripping preparation. The hook module 3 starts to drag the material frame 1 under the drive of the first drive device 36. At the same time, the second drive device 44 of the transmission component 4 is started, driving the conveyor belt 41 to rotate and assisting the material frame to move. When the material frame 1 is dragged until the bottom 2 / 3 is above the platform, the transmission component 4 stops working, and the servo motor 32 drives the hook 31 to rotate to a flat position and hide under the material frame 1. The transmission component 4 is restarted, transporting the material frame 1 to the center of the feeding platform 2. Under the action of the guide plate 5, the material frame is kept in the central position. The feeding platform 2 is transported by the aisle trolley to the next fixed point of the shelf B. The conveying component 4 starts to rotate, transporting the material frame 1 to the empty location of the shelf B, and stops when the material frame is transported to 2 / 3 of its length. The hook module 3 is located below the material frame 1. It is driven to move to the other side of the material frame by the first drive device 36. The servo motor 32 drives the hook 31 to rotate to an upright position, ready to push the material frame outside the handle 11 of the material frame 1. The transmission component 4 continues to move, and in conjunction with the push of the hook module 3, it completely transports the material frame 1 to the target storage location on the shelf B. Beneficial effects The device employs a configuration of a material frame 1, a feeding platform 2, a hook module 3, a transmission component 4, and a guide plate 5. Through the coordinated operation of the hook module 3 and the transmission component 4, cross-shelf operations can be achieved, allowing goods to be retrieved from shelf A and directly placed on shelf B, significantly improving the flexibility of warehousing operations. The hook 31 of the hook module 3 can rotate 90 degrees and move linearly along the linear guide rail 35. Combined with the synchronous belt drive of the conveyor belt 41 of the transmission component 4, the gripping, moving, and placing of the material frame 1 becomes smoother and more efficient, reducing unnecessary intermediate operations, shortening storage and retrieval time, and improving overall warehousing efficiency. The handles 11 on both sides of the material frame 1 provide reliable gripping points for the hook 31. The guide plate 5 ensures that the material frame 1 always moves along the central path on the feeding platform 2. The synchronous belt drive structure of the conveyor belt 41 and pulleys 42 ensures the accuracy of transmission. All of these factors contribute to a more stable and reliable storage and retrieval operation, reducing the risk of the material frame 1 tipping over or shifting. The components are compactly arranged, and the retractable design of the hook 31 in the hook module 3 saves space. The symmetrically arranged transmission components 4 and guide plates 5 ensure the balance of the device during operation. The overall structure is simple and easy to maintain, reducing the failure rate and maintenance costs of the equipment. Based on the standard material frame 1, the device can be adapted simply by adding handles 11, without the need for large-scale replacement of existing material frames in the warehouse. This facilitates its promotion and application in existing warehousing systems and adapts to the needs of different types of warehousing scenarios.
