[0089] See Figures 1 to 9This invention provides a cargo storage and retrieval mechanism 10, including a base 1, a support component 2, and a transfer mechanism 3. The base 1 is configured to provide support. The support component 2 includes a pallet assembly 21, which is vertically and flexibly mounted on the base 1. The transfer mechanism 3 is movably mounted on the base 1. When the support component 2 is in a raised state, a channel is formed between the support component 2 and the base 1, allowing the transfer mechanism 3 to pass through; when the support component 2 is in a lowered state, the transfer mechanism 3 is configured to move the cargo 4 carried by the support component 2 by pushing, pulling, or other methods.

[0090] The supporting component 2 includes a cargo support surface for supporting the cargo 4, specifically the surface of the pallet 212 described later. The height of the cargo support surface is adjustable. By adjusting the height of the cargo support surface, the transfer mechanism 3 can avoid the cargo 4 without needing to descend; and it can retrieve goods from one of two adjacent shelves 7 and place them on the other shelf 7. That is, using the same cargo storage and retrieval mechanism 10, the operation of retrieving and placing goods 4 from opposite sides can be realized, resulting in high efficiency in cargo storage and retrieval operations.

[0091] The pallet assembly 21 of the load-bearing component 2 can be made of aluminum alloy, and the surface of the pallet 212 is flat and smooth to reduce friction when the goods 4 move. The pallet assembly 21 can be lifted and lowered by an electric cylinder or by a linkage mechanism described later.

[0092] When needed, the pallet assembly 21 of the supporting component 2 is raised to avoid the transfer mechanism 3. After the pallet assembly 21 and the transfer mechanism 3 are separated, the transfer mechanism 3 can move freely on the base 1. When picking up goods, the transfer mechanism 3 pulls the goods 4 to transfer the goods 4 from the shelf 7 to the supporting component 2. When storing goods, the transfer mechanism 3 pushes the goods 4 to transfer the goods 4 from the supporting component 2 to the shelf 7.

[0093] In the above technical solution, when the supporting component 2 is raised, a channel is formed between it and the base 1, allowing the transfer mechanism 3 to pass smoothly without the need for additional space to avoid it. This method can easily change the position of the transfer mechanism 3 on the base 1, enabling the retrieval of goods from opposite sides, adapting to different layouts of the shelving 7, and improving the versatility of the goods storage and retrieval mechanism 10.

[0094] In some embodiments, the base 1 includes a support member 11, a support guide assembly 12, and a fixing plate 13.

[0095] The support member 11 is configured to provide support, specifically, it can be two separately arranged support beams. The support beams are made of metal, such as steel or aluminum alloy profiles. The cross-sectional shape of the support beams can be square, circular, or I-shaped, to adapt to different mechanical requirements. The two support beams are parallel, forming a horizontal support surface. The cargo storage and retrieval mechanism 10 is mounted on the lifting rail, i.e., the second rail 6 described later, via a connecting plate 16 fixedly connected to the support member 11, to achieve the overall lifting and lowering of the cargo storage and retrieval mechanism 10.

[0096] The support guide assembly 12 guides the linear movement of the transfer mechanism 3, ensuring smooth and stable movement without wobbling. The support guide assembly 12 includes a support plate 121 and a slide rail 122. The bottom of the support plate 121 is fixedly connected to the support member 11, and the slide rail 122 is fixedly installed on the top of the support plate 121, which can be achieved by bolting or welding. The support plate 121 can be designed as a flat plate. The support plate 121 and the support member 11 are arranged perpendicularly and welded to form a frame to provide sufficient strength and stability. The transfer mechanism 3 includes a connector 35, which is slidably connected to the slide rail 122. The slide rail 122 is a linear guide with a smooth surface, effectively reducing friction during the movement of the transfer mechanism 3 and ensuring high-precision linear movement along the slide rail 122. The connector 35 moves linearly along the slide rail 122 to achieve smooth and stable linear movement of the transfer mechanism 3.

[0097] The fixed plate 13 is fixedly installed on the support member 11, specifically connected by a ball joint 15. This installation method can effectively buffer impact forces from different directions, protect the overall structure of the cargo storage and retrieval mechanism from damage, and extend the service life of the equipment. The pallet assembly 21 of the load-bearing component 2 is rotatably installed on the fixed plate 13 to achieve lifting.

[0098] In some embodiments, the pallet assembly 21 includes a baffle 211 and a pallet 212 integrally formed or fixedly connected to the baffle 211. When the pallet 212 and the baffle 211 are integrally formed, they can be made into a whole by casting to ensure the strength of the connection; they can also be fixed by welding, which can form a high-strength connection for metal materials; or they can be connected by bolts and nuts, which facilitates disassembly and maintenance, and the bolts can be evenly distributed at the connection between the pallet 212 and the baffle 211.

[0099] The baffle 211 and the pallet 212 are arranged intersectingly, specifically vertically. When arranged vertically, it effectively prevents the goods 4 from falling off the pallet 212, acting as a limiting mechanism. When the baffle 211 and pallet 212 are placed horizontally, they cooperate with the transfer mechanism 3 to provide a stable support surface for the transfer mechanism 3 to handle the goods 4. The pallet 212 holds the goods 4, and the baffle 211 prevents the goods 4 from falling off the edge. There is sliding friction between the goods 4 and the pallet 212. One of the baffle 211 and pallet 212 is rotatably connected to the fixing plate 13 of the base 1. When it is necessary to lift the pallet assembly 21 to adapt to different handling scenarios, the baffle 211 can be rotated to enhance the adaptability of the equipment.

[0100] The transfer mechanism 3 causes the goods 4 to slide on the pallet 212. Compared with rolling friction, the sliding friction between the goods 4 and the pallet 212 can better control the stability and accuracy of the movement of the goods 4, and prevent the goods 4 from getting out of control due to rolling. The transfer mechanism 3 can use various methods such as hooks and suction to act on the goods 4, for example, using hooks or suction cups to apply a force to move the goods 4.

[0101] The above technical solution allows the transfer mechanism 3 to move precisely in a straight line under the guidance of the support guide component 12, improving the accuracy and efficiency of handling goods 4. The smooth movement reduces swaying and ensures the safety of goods 4 during transport. The rotatable installation of the load-bearing component 2 enables lifting, flexibly meeting the requirements of different positions of the transfer mechanism 3, and facilitating storage and retrieval operations, thus improving the equipment's versatility. Furthermore, the overall structure is simple and compact, with stable connections between components, facilitating installation, maintenance, and debugging, and reducing operating costs.

[0102] In some embodiments, the support assembly 2 further includes a first drive assembly 22, which is mounted on the base 1 and drivenly connected to the pallet assembly 21. The first drive assembly 22 is configured to drive the pallet assembly 21 to swing relative to the base 1, thereby realizing the lifting and lowering of the pallet assembly 21 relative to the base 1.

[0103] In some embodiments, the first drive assembly 22 includes a first drive section 221 and a linkage assembly 222.

[0104] The first drive unit 221 is mounted on the base 1. The first drive unit 221 can be a motor, such as a servo motor, which can precisely control the rotation angle and speed to ensure the accuracy and stability of the lifting and lowering action of the pallet assembly 21. The motor can be fixed to the fixing plate 13 of the base 1 by bolts to enhance the stability of the installation.

[0105] The linkage assembly 222 includes an active linkage 222a and a passive linkage 222b. The first drive unit 221 drives the active linkage 222a to rotate, thereby causing the pallet assembly 21 to rotate relative to the base 1 via the passive linkage 222b.

[0106] There is one active link 222a and multiple passive links 222b, such as 2-4. The passive links 222b are divided into two groups, distributed on both sides of the active link 222a.

[0107] The drive link 222a is typically made of metal, such as alloy steel, possessing sufficient strength and toughness to prevent deformation or breakage during operation. The first end of the drive link 222a is connected to the output shaft of the first drive unit 221 via a coupling. The coupling effectively transmits torque and allows for a certain degree of axial and radial misalignment, ensuring reliable connection. The second end of the drive link 222a is rotatably connected to the support plate assembly 21 via a pin.

[0108] The first end of the passive link 222b is rotatably connected to the base 1, and the second end of the passive link 222b is rotatably connected to the support plate assembly 21. The passive links 222b are also made of metal, and 2-4 passive links 222b are evenly divided into two groups, symmetrically distributed on both sides of the active link 222a. The first end of each group of passive links 222b is rotatably connected to the fixing plate 13 of the base 1 via a hinge pin, allowing for flexible rotation. The second end of the passive link 222b is also rotatably connected to the baffle 211 of the support plate assembly 21 via a pin pin, similar to the connection method of the active link 222a.

[0109] In the above technical solution, after the first drive unit 221 is activated, the active connecting rod 222a drives the passive connecting rods 222b on both sides to move in coordination, thereby precisely driving the pallet assembly 21 to rise and fall smoothly and efficiently. On the one hand, the precise control of the servo motor can meet the lifting requirements of different heights, improving the versatility of the equipment; on the other hand, the layout design of the connecting rod assembly 222 ensures that the pallet assembly 21 is subjected to uniform force during the lifting process, enhancing structural stability and preventing the pallet assembly 21 from tilting or the goods 4 from slipping due to uneven force. At the same time, the rotating connection method between the components facilitates maintenance and replacement, reducing the maintenance cost of the equipment.

[0110] See Figures 10 to 13 In some embodiments, there are two pallet assemblies 21, which are arranged separately; the transfer mechanism 3 is located between the two pallet assemblies 21.

[0111] The two pallet assemblies 21 can be arranged symmetrically and distributed to the left and right of the transfer mechanism 3 to ensure that the cargo 4 is subjected to uniform force in the horizontal direction when the transfer mechanism 3 moves between them. The two pallet assemblies 21 jointly support the cargo 4, making the force on the cargo 4 stable and the movement smoother. The size of the two pallet assemblies 21 can be customized according to the size of common cargo 4 to ensure that it can fully support the cargo 4 and avoid the cargo 4 being suspended or unstable during the carrying process.

[0112] The transfer mechanism 3 is located between the two pallet assemblies 21. The distance between the transfer mechanism 3 and the pallet assembly 21 can be precisely designed to ensure that the transfer mechanism 3 can smoothly move between the two to transport goods 4, while avoiding excessive distance that would cause the goods 4 to shake during the transfer process.

[0113] The above-described technical solution, by having two separately arranged pallet assemblies 21 jointly support the goods 4, effectively distributes the weight of the goods 4, making the force on the goods 4 more stable during the carrying and transfer process. This reduces swaying or displacement caused by uneven force distribution, thereby improving the stability and accuracy of the goods 4 transfer. This contributes to improving the efficiency and safety of the entire goods handling process and reducing the risk of damage to the goods 4. At the same time, this layout also optimizes space utilization, making the equipment structure more compact and rational.

[0114] In some embodiments, the swing range of the pallet assembly 21 is 0-180°. To meet the 0-180° swing range, the first drive unit 221 has sufficient torque and rotation angle control capability. The motor can be equipped with an angle sensor to accurately monitor and provide feedback on the swing angle of the pallet assembly 21 for precise control.

[0115] When the swing angle of the pallet assembly 21 is 0°, the position of the pallet assembly 21 is the low position, such as... Figure 14 As shown, the pallet assembly 21 is located on the side of the transfer mechanism 3 near the first end of the base 1. Figure 14 Taking the orientation shown as an example, pallet assembly 21 is located on the left and transfer mechanism 3 is on the right. This allows for convenient retrieval of goods from the shelf 7 on the right side of the goods storage and retrieval mechanism 10. The labels "first end" and "second end" in the accompanying drawings refer to the first end and second end of base 1, respectively.

[0116] When the swing angle of the pallet assembly 21 is 90°, the position of the pallet assembly 21 is at its high position, such as... Figure 15 As shown, a channel is formed between the pallet assembly 21 and the base 1, allowing the transfer mechanism 3 to pass through. When swung to a 90° high position, the channel between the pallet assembly 21 and the base 1 allows the transfer mechanism 3 to pass smoothly. This design effectively utilizes space, allowing the transfer mechanism 3 to move freely to the left and right sides of the pallet assembly 21 without obstruction, thus improving the flexibility of the transfer mechanism 3's position.

[0117] When the swing angle of the pallet assembly 21 is 180°, the position of the pallet assembly 21 is the low position, such as... Figure 16As shown, pallet assembly 21 is located on the second end of the transfer mechanism 3 near the base 1. When swung to the 180° low position, pallet assembly 21 is located at the second end of the transfer mechanism 3 near the base 1. Compared to the 0° position, pallet assembly 21 is on the right and transfer mechanism 3 is on the left. This positional change allows transfer mechanism 3 to avoid the load-bearing component 2 without lifting or lowering, saving time required for accessing goods 4 from the opposite side.

[0118] When the pallet assembly 21 swings from 0° to 180°, even if the position of the transfer mechanism 3 on the base 1 remains unchanged, the relative positions of the pallet assembly 21 and the transfer mechanism 3 along the length of the base 1 change. For example, with Figure 1 Taking the left-right direction as an example, initially the transfer mechanism 3 is on the left and the pallet assembly 21 is on the right. After the pallet assembly 21 swings 180°, their relative positions become: pallet assembly 21 on the left and transfer mechanism 3 on the right. This technical solution transforms the pulling operation of the transfer mechanism 3 into a pushing operation, increasing operational flexibility, improving the practicality and adaptability of the entire handling system, and better meeting the diverse handling needs of goods.

[0119] In some embodiments, the transfer mechanism 3 includes a cargo execution mechanism configured to switch its orientation so that after the cargo 4 carried by the pallet assembly 21 is moved from one side to the other side, the cargo execution mechanism acts on the other side of the cargo 4.

[0120] In this article, switching its own orientation refers to the cargo actuator changing the orientation of its effective working parts (such as the hook end or suction surface) by adjusting its own posture (such as rotation, flipping, or swinging) or selecting a function (changing its state), thereby enabling it to operate on cargo 4 in different positions. There are many ways for a cargo actuator to switch its own orientation.

[0121] Cargo execution mechanisms can employ various methods such as suction cups and hooks.

[0122] There are many ways to install suction cups and hooks. For example, the suction cup (hook) can be installed on a rotatable part, such as on a rotating shaft. By rotating the shaft, the orientation of the suction cup (hook) can be changed to meet the operational needs of goods 4 in different positions.

[0123] Another possible implementation is to have two sets of suction cups (hooks), each set corresponding to the operation requirements of goods 4 at a specific location. If operation is required on goods 4 at different locations, simply select the corresponding suction cup (hook).

[0124] Another possible implementation is that the suction cup (hook) can be installed in a swingable manner, so as to operate the goods 4 in different positions by swinging the suction cup (hook) to different positions.

[0125] For the suction cup implementation, the suction cup assembly includes a plate body and a connecting air tube. The plate body is made of rubber, is elastic, and has a flat surface. It is connected to an external vacuum generator via the air tube. One end of the air tube is tightly connected to the center of the back of the suction cup plate body, and the other end is connected to the vacuum system. Regardless of which side of the goods 4 the transfer mechanism is located on, as long as the opening of the suction cup faces the goods 4, it can achieve adsorption. The suction cup causes minimal damage to the surface of the express packaging box, can adapt to packaging box surfaces of different shapes, and provides stable adsorption.

[0126] The implementation method using hooks will be explained in detail later, and will not be repeated here.

[0127] See Figures 7 to 9 In some embodiments, the transfer mechanism 3 includes a mounting base 31, a hook assembly 32, and a second drive assembly 33.

[0128] Mounting base 31 can be linearly slidably mounted on base 1 along the direction in which the cargo 4 enters and exits the bearing component 2. Mounting base 31 can be made of metal material such as aluminum alloy, which is lightweight and high-strength. A connector 35 is installed at its bottom. The connector 35 cooperates with the linear guide rail set on base 1 to realize linear sliding along the direction in which the cargo 4 enters and exits the bearing component 2.

[0129] Two hook assemblies 32 can be mounted on the mounting base 31. The two hook assemblies 32 are connected by a rotating shaft 34, so that the same second drive assembly 33 can drive both hook assemblies 32 to move simultaneously. The two hook assemblies 32 are distributed along the width direction, that is, along... Figure 12 The hooks are arranged in opposite directions, one up and one down, and the two hook assemblies 32 have the same structure. When operating the same box, the two hook assemblies 32 work together to make the box more evenly stressed, avoiding tilting or damage to the box due to uneven stress, ensuring the smooth movement of the box during handling, and improving the safety and stability of handling the goods.

[0130] The hook assembly 32 includes a fixedly connected body 321, a first hook 322, and a second hook 323. These three components can be integrally formed or manufactured separately and then assembled together. The body 321 is rotatably mounted to the mounting base 31 via a pin to reduce rotational friction. The first hook 322 is fixedly connected to the first end of the body 321 at its rotatable connection to the mounting base 31, and the second hook 323 is fixedly connected to its second end. The first hook 322 and the second hook 323 are located at opposite ends of the body 321. The hook assembly 32 rotates relative to the body 321, allowing either the first hook 322 or the second hook 323 to be in a working position. A second drive assembly 33 is mounted on the mounting base 31 and driven by the body 321 to drive the hook assembly 32 to rotate relative to the mounting base 31.

[0131] The hook assembly 32 can move horizontally along the length X of the base 1. Using either the first hook 322 or the second hook 323, goods 4 can be hooked and pulled onto the pallet 212 to complete the retrieval. Alternatively, goods 4 can be pushed onto the storage location on the shelf 7 using either the first hook 322 or the second hook 323 to complete the storage operation. This flexible operation method meets the storage and retrieval needs of goods 4 in different scenarios, improving the versatility of the equipment. The first hook 322 and the second hook 323 switch positions by swinging or rotating, resulting in flexible movements, rapid response, and quick adaptation to different working conditions.

[0132] As described above, the pallet assembly 21 is height-adjustable. Specifically, under the drive of the first drive unit 221, the pallet assembly 21 is raised or lowered by swinging the linkage assembly 222. Figure 10 The diagram illustrates the first position, where the pallet assembly 21 is docked with a storage location on the left-hand shelf 7. When it is necessary to store goods 4 or retrieve a box to the right, the pallet assembly 21 swings via a linkage to switch to the second position, docking with the storage location on the right-hand shelf 7. During the swing from the first to the second position, the pallet assembly 21 passes through a third position, which is its highest point. When the pallet assembly 21 swings the goods 4 to its highest point, the hook assembly 32 can pass under the goods 4, moving from one side to the other. This movement allows the hook assembly 32 to switch its action from one side of the goods 4 to the other side, thus enabling the storage of boxes on the other side.

[0133] In some embodiments, the second drive assembly 33 includes a second drive unit 331 and a crank-rocker mechanism 332. The second drive unit 331 is fixedly mounted on the mounting base 31. One end of the crank-rocker mechanism 332 is drivenly connected to the second drive unit 331, and the other end of the crank-rocker mechanism 332 is rotatably connected to the body 321 of the hook assembly 32; the second drive unit 331 drives the hook assembly 32 to rotate relative to the mounting base 31 through the crank-rocker mechanism 332.

[0134] The second drive unit 331 uses a servo motor, which is small in size and has high control precision. The servo motor is fixedly mounted on the mounting base 31 and secured by bolts or clips. The crank-rocker mechanism 332 consists of multiple rotating arms, which can be made of metal to ensure strength and rigidity. One end of the crank-rocker mechanism 332 is connected to the output shaft of the servo motor, and the other end is rotatably connected to the hook assembly 32 body 321. The servo motor drives each arm of the crank-rocker mechanism 332 to rotate, thereby precisely driving the entire hook assembly 32 to rotate, realizing the switching between the positions of the first hook pick 322 and the second hook pick 323, ensuring accurate selection of the working position, and improving work efficiency and operational accuracy.

[0135] In some embodiments, the goods storage and retrieval mechanism 10 further includes a third drive mechanism 14, located between the two pallet assemblies 21 of the support assembly 2. The third drive mechanism 14 includes a third drive section 141 and a synchronous pulley mechanism 142. The third drive section 141 is mounted on the support member 11 of the base 1. The synchronous pulley mechanism 142 includes at least two synchronous pulleys 142a and a synchronous belt 142b wound around the synchronous pulleys 142a. The third drive section 141 is drivenly connected to one of the synchronous pulleys 142a. The transfer mechanism 3 is fixedly connected to the synchronous belt 142b to move with the synchronous belt 142b. The third drive section 141 is, for example, a motor, which drives the synchronous pulleys 142a to rotate, thereby driving the synchronous belt 142b to move, realizing the linear movement of the transfer mechanism 3.

[0136] The third drive mechanism 14 is singular, requiring only one to drive the transfer mechanism 3 in a linear motion. The transfer mechanism 3 can move linearly, pulling goods 4 from the outside onto the carrying component 2, or pushing goods 4 from the carrying component 2 onto the shelf 7. This technical solution effectively drives the transfer mechanism 3 in a linear motion with only one third drive mechanism 14, resulting in a simple and compact structure that eliminates the need for multiple third drive mechanisms to work together, thus reducing equipment costs and space requirements. Through the linear movement of the transfer mechanism 3, the carrying component 2 can both pull goods 4 from the outside onto the carrying component 2 and push goods 4 from the carrying component 2 onto the shelf 7, achieving efficient transfer of goods 4 between different locations, optimizing the goods storage and retrieval process, and improving overall work efficiency.

[0137] This invention also provides a bin-based automated storage and retrieval system, including the cargo storage and retrieval mechanism 10 provided by any of the technical solutions of this invention.

[0138] In some embodiments, the automated storage and retrieval system further includes at least two first tracks 5 and at least two second tracks 6. The at least two first tracks 5 are spaced apart in at least one direction, with the length direction of the first tracks 5 being, for example, horizontal. Each second track 6 is movably arranged along the at least two first tracks 5 via a traveling mechanism, with the length direction of the second track 6 being, for example, vertical. A goods storage and retrieval mechanism 10 is movably mounted on the second tracks 6, and the goods storage and retrieval mechanism 10 can be raised and lowered to correspond to storage positions at different heights.

[0139] The second track 6 of the automated storage and retrieval system works in conjunction with the first track 5. The second track 6 is movably installed on the first track 5 so as to change the position of the goods storage and retrieval mechanism 10, and ultimately realize the storage and retrieval operations of storage locations at the same height but different positions.

[0140] The automated storage and retrieval system also includes shelves 7, with the first track 5 installed on the shelves 7. A buffer support 8 is installed below the shelves 7, on which goods 4 transported by AGV trolleys can be placed.

[0141] Shelf 7 is made of metal, such as high-quality steel, which has high strength and good stability, and can bear the weight of goods 4 for long-term use. The first track 5 extends along the surface of shelf 7 and can be fixed to the surface of shelf 7 by welding or bolting.

[0142] like Figure 1 As shown, in some embodiments, there are two shelves 7, which are adjacent to each other. One of the shelves 7 is equipped with a goods storage and retrieval mechanism 10, which is configured to transfer goods 4 from one shelf 7 to the other shelf 7, and to store and retrieve goods 4 on the same shelf 7. Figures 11-13 The diagram illustrates the crossbeams 71 of two adjacent shelves 7.

[0143] When two adjacent shelves 7 exist, the goods storage and retrieval mechanism 10 is installed on one of the shelves 7, using one mechanism 10 to perform storage and retrieval operations on both shelves 7. This layout saves space and improves the utilization rate of the warehouse area. The goods storage and retrieval mechanism 10 can flexibly realize the storage and retrieval operations of goods 4 on the same shelf 7, meeting the daily storage and retrieval needs of goods 4. At the same time, it can also transfer goods 4 from one shelf 7 to another, facilitating the classification, allocation, or replenishment of goods 4, enhancing the flexibility and functionality of warehouse operations.

[0144] Two adjacent shelves 7 work collaboratively using the same goods storage and retrieval mechanism 10, optimizing the warehousing and logistics process. The goods storage and retrieval mechanism 10 enables efficient and convenient transfer of goods 4 between shelves 7, reducing the workload and time costs of manual handling and improving the overall efficiency of warehousing and logistics. Furthermore, this system layout makes the storage and management of goods 4 more orderly, enhancing the accuracy and convenience of warehouse management.

[0145] See Figures 14 to 17 This invention also provides a goods storage and retrieval method for transferring goods 4 between two adjacent shelves 7. The goods storage and retrieval method is implemented using the goods storage and retrieval mechanism 10 provided by any technical solution of this invention, and includes the following steps:

[0146] In step one, the transfer mechanism 3 moves the goods 4 from the first shelf 7 to the pallet assembly 21 of the carrying component 2. In this step, the hook assembly 32 of the transfer mechanism 3 is precisely aligned with the hook groove 41 of the goods 4. The first hook 322 or the second hook 323 in the hook assembly 32 works according to the actual situation, and uses its cooperation with the hook groove 41 to hook the goods 4 from the shelf 7 onto the pallet assembly 21. This process requires the transfer mechanism 3 to be precisely positioned to ensure accurate hooking and avoid damage to the goods 4 from collision.

[0147] Step two: The transfer mechanism 3 detaches from the goods 4. In step two, when the transfer mechanism 3 detaches from the goods 4, it is necessary to ensure that the goods 4 are stably placed on the pallet assembly 21. This relies on the pallet assembly 21 providing good support for the goods 4, and the transfer mechanism 3 detaching smoothly to prevent the goods 4 from tipping over due to shaking.

[0148] In step three, the pallet assembly 21 and the cargo 4 are lifted together to form a passageway for the transfer mechanism 3. The purpose of lifting is to increase the height of the cargo 4, allowing the hook assembly 32 to change position through horizontal movement. In step three, the pallet assembly 21, under the action of the first drive assembly 22, lifts the cargo 4. The motor of the first drive assembly 22 precisely controls the swing angle of the pallet assembly 21, raising the height of the cargo 4 and creating conditions for the hook assembly 32 of the transfer mechanism 3 to change position horizontally. This process ensures a smooth ascent of the cargo 4, preventing it from falling due to shaking or tilting.

[0149] Step four, the transfer mechanism 3 moves along the base 1 to move from one side of the pallet assembly 21 to the other side of the pallet assembly 21. In step four, the transfer mechanism 3 moves smoothly along the track on the base 1 from one side of the pallet assembly 21 to the other side.

[0150] In step five, the pallet assembly 21 rotates the goods 4 away from the transfer mechanism 3, and both the pallet assembly 21 and the goods 4 are lowered. This operation serves two purposes: first, it connects to the target storage location, and second, it provides operating space for the transfer mechanism 3. In step five, the pallet assembly 21 rotates the goods 4 away from the transfer mechanism 3, lowering the goods 4. This action, on the one hand, connects to the target storage location, ensuring that the goods 4 are accurately placed in the appropriate position; on the other hand, it provides subsequent operating space for the transfer mechanism 3. The entire rotation process is precisely controlled, ensuring the accurate placement of the goods 4.

[0151] Step six: The goods storage and retrieval mechanism 10 moves to the position corresponding to the second shelf 7. These two shelves 7 are adjacent. In step six, the goods storage and retrieval mechanism 10 moves to the position corresponding to the second shelf 7 by means of its cooperation with the first track 5 and the second track 6. During the movement, the drive device of the goods storage and retrieval mechanism 10 precisely controls the moving speed and position to ensure accurate stopping at the second shelf 7.

[0152] In step seven, the transfer mechanism 3 pushes the goods 4 along the pallet assembly 21 until it is pushed onto the second shelf 7. During this process, the transfer mechanism 3 applies a uniform and stable pushing force to ensure the goods 4 smoothly enters its storage position on the second shelf 7.

[0153] Both sides of the goods 4 are provided with hook grooves 41 that cooperate with the hook assembly 32 of the transfer mechanism 3. This allows the goods storage and retrieval mechanism 10 to operate on the goods 4 from either side, greatly improving the flexibility of goods storage and retrieval. When the hook groove 41 faces downwards, the hook assembly 32 extends into the hook groove 41 by lifting the hook. If the orientation of the hook groove 41 changes, the hooking method is adjusted accordingly. This allows the goods storage and retrieval mechanism 10 to operate from either side of the goods 4, adapting to goods 4 placed in different orientations.

[0154] This goods storage and retrieval method firstly enables efficient retrieval and storage between two adjacent shelves 7, meeting the needs of narrow aisles and opposite-side retrieval in high-density storage, thus improving warehouse space utilization and goods storage and retrieval efficiency. Secondly, it eliminates the need for conveyor belts, reducing complex transmission components and lowering failure rates and control complexity. Furthermore, the hook assembly 32 can hook the goods 4 onto the carrying assembly 2 or push them into the storage location in one step, making operation convenient. In addition, the swinging motion of the pallet assembly 21 not only allows the hook assembly 32 to change the pushing direction but also enables connection to storage locations on both sides even with a short width of the goods storage and retrieval mechanism, achieving opposite-side retrieval and narrow aisle storage and retrieval needs. This makes it well-suited for high-density automated warehouses, optimizing warehouse layout.

[0155] This invention also provides a goods storage and retrieval method for retrieving and storing goods from the same shelf 7, i.e., same-side storage and retrieval. This goods storage and retrieval method is implemented using the goods storage and retrieval mechanism 10 provided by any technical solution of this invention, and includes the following steps:

[0156] First, the transfer mechanism 3 moves the goods 4 from the first storage position of the shelf 7 to the pallet assembly 21 of the carrying component 2. In this step, the hook assembly 32 of the transfer mechanism 3 precisely positions the goods 4 in the first storage position of the shelf 7. The hook assembly 32 is precisely controlled to rotate by the second drive assembly 33, so that the appropriate hook (first hook 322 or second hook 323) is aligned with the hook groove 41 of the goods 4. By using the cooperation between the hook and the hook groove 41, the goods 4 are smoothly hooked from the first storage position onto the pallet assembly 21.

[0157] Next, the goods storage and retrieval mechanism 10 moves to the second storage position corresponding to the shelf 7. The goods storage and retrieval mechanism 10 moves to the second storage position of the shelf 7 under external drive.

[0158] Finally, the transfer mechanism 3 pushes the goods 4 along the pallet assembly 21 until it is placed in the second storage position of the shelf 7. In this step, the transfer mechanism 3 smoothly moves the goods 4 along the pallet assembly 21 until it is accurately placed in the second storage position of the shelf 7. During the pushing process, the transfer mechanism 3 must apply a uniform and stable pushing force, and the pallet assembly 21 must remain horizontal and stable to prevent the goods 4 from shifting or tipping over during the pushing process.

[0159] As can be seen, the above technical solution enables the retrieval and storage of goods from the same shelf 7, achieving same-side access and retrieval, which is efficient and convenient. Compared to other complex retrieval and storage methods, this method has simple and clear operation steps, reduces unnecessary intermediate steps, and greatly improves the efficiency of goods storage and retrieval 4. At the same time, relying on the precise cooperation of the various components of the goods storage and retrieval mechanism 10, it reduces the difficulty of operation, improves the accuracy and stability of goods storage and retrieval 4, and can better meet the needs of rapid storage and retrieval of the same shelf 7 in warehousing and logistics.
