Description

Technical Field

[0001] This utility model relates to a short-trip automated transit logistics warehouse. Background Technology

[0002] With the rapid development of the modern logistics industry, in logistics and distribution fields such as express delivery, storage and distribution of hardware parts in factories, transfer and distribution of consumables in factory production workshops, unmanned vending machines, and food delivery, the final stage of goods delivery is still largely completed manually, making it impossible to achieve fully automated processes. For example:

[0003] (1) Express delivery and logistics: When express delivery arrives at an individual's hands, it needs to be temporarily stored at various express delivery stations or comprehensive stations (such as Cainiao Station) for the recipient to pick up. This method has the problems of messy express delivery tracking, risk of errors, and inability to pick up the package at any time 24 hours a day; or it can be placed in a temporary storage cabinet (such as Hive). The storage capacity of this method is affected by the area and height of the temporary storage cabinet, and the storage capacity cannot meet the needs of users in areas with a large number of people.

[0004] (2) Factory hardware storage and distribution: Large-scale production plants have a wide variety of spare parts, maintenance tools, consumables, etc. for various production equipment. However, the number of categories is not enough to support the construction of a large-scale warehousing system. Currently, they are all manually put into and out of the warehouse and delivered to the production site by workers or maintenance personnel. This is inefficient, difficult to trace, and prone to loss.

[0005] (3) Transfer and distribution of consumables in factory production workshop: During the production process, consumables such as packaging materials and production parts are transferred from the main warehouse to the corresponding buffer area by the corresponding transfer group or transfer equipment. The production personnel then take away the materials placed in the buffer area.

[0006] (4) Unmanned vending: Unmanned vending is limited by the height and floor space of current cabinet-type unmanned vending machines, resulting in fewer product categories and the inability to connect unmanned vending machines with delivery robots;

[0007] (5) Food delivery: Currently, food delivery cannot be fully automated and relies mainly on manual delivery.

[0008] In existing technologies, warehouses with buffering functions, such as unmanned parcel lockers and vending machines, have fixed storage dimensions. If there are many different types of goods and significant differences in size, large items may not fit, or small items may occupy large storage spaces. Furthermore, the buffering capacity of unmanned parcel lockers and vending machines is relatively low due to the height at which people retrieve their items and the floor space required.

[0009] Due to the box-type, separate structure of unmanned express delivery lockers and vending machines, they cannot achieve automatic warehousing and outbound operations, nor can they automatically connect with existing unmanned vehicles or delivery personnel to complete the automatic warehousing and outbound operations of goods.

[0095] Please see Figure 8 , Figure 9 , Figure 10 , Figure 11 and Figure 12 In the short-stroke automated transit logistics warehouse of this utility model, the column stacker crane 1 includes a supporting column 8, a column mounting base 12, a bidirectional rotating fork 11, a bidirectional output right-angle reducer 16, a servo motor with a brake 17, and two steel cables.

[0096] The support column 8 is located in the middle of the odd-shaped shelf 2. Its top is connected to an upper support column bracket 7 via screws, and steel cable guide wheels 6 are installed on both sides of the upper support column bracket 7. The bottom of the support column 8 is connected to a lower support column bracket 13 via screws, and the lower support column bracket 13 is mounted on the support column mounting base 12. The support column mounting base 12 is fixed to the ground with expansion bolts, thus fixing the bottom of the support column 8. The upper support column bracket 7 is connected to the odd-shaped connecting block 62 on the top cover of the odd-shaped shelf 2 via screws, thus fixing the top of the support column 8.

[0097] The servo motor 17 with brake and the bidirectional output right-angle reducer 16 are respectively mounted on the column mounting base 12, and the output end of the servo motor 17 with brake is connected to the bidirectional output right-angle reducer 17. The two output ends of the bidirectional output right-angle reducer 17 are respectively connected to the left-hand winch 15 and the right-hand winch 14 through key pins.

[0098] The bidirectional rotating fork 11 is movably mounted on the support column 8. The bidirectional rotating fork 11 is equipped with a steel cable traction buckle 1 25 and a steel cable traction buckle 28. One end of the two steel cables is connected to the steel cable traction buckle 1 25 and the steel cable traction buckle 28 respectively. The other end of the two steel cables passes over two steel cable guide wheels 6 and is connected to the left-hand winch 15 and the right-hand winch 14 respectively. When the brake-equipped servo motor 17 rotates, it drives the left-hand winch 15 and the right-hand winch 14 to rotate, pulling the two steel cables to retract and extend synchronously, thereby driving the bidirectional rotating fork 11 to move up and down. The cable guide groove of the left-hand winch 15 is left-handed, and the cable guide groove of the right-hand winch 14 is right-handed. During the process of the left-hand winch 15 and the right-hand winch 14 retracting the cable, the two cables deviate in opposite directions. During the process of the left-hand winch 15 and the right-hand winch 14 releasing the cable, the two cables deviate in opposite directions. This structure can prevent interference between the cable and the bidirectional rotating fork 11 during the pulling process.

[0099] Please see again Figure 13 , Figure 14 , Figure 15 , Figure 16 , Figure 17 and Figure 18 The bidirectional rotating fork 11 includes a first fork 18, a second fork 19, a first linear guide module 20, a second linear guide module 29, an external tooth rotating support gear 30, a gear mounting bracket 31, a servo motor 32, and a module mounting bracket 33.

The output end of the servo motor 32 is equipped with a drive gear, and the drive gear meshes with the gear of the moving ring of the external tooth rotary support gear 30. When the servo motor 32 rotates, it drives the external tooth rotary support gear 30 to rotate, which in turn drives the module mounting bracket 33 to rotate, thereby driving the entire bidirectional rotary fork 11 to rotate.

[0101] Please see again Figure 18The gear mounting bracket 31 is slidably mounted on the support column 8. Specifically, the support column 8 is vertically equipped with a linear guide rail 10 and a circular guide rail 9. The inner ring of the gear mounting bracket 31 is equipped with a linear slider mounting bracket 35 and a circular slider mounting bracket 37. A linear slider 36 is mounted on the linear slider mounting bracket 35, and a circular slider 38 is mounted on the circular slider mounting bracket 37. The linear slider 36 is slidably mounted on the linear guide rail 10, and the circular slider 38 is slidably mounted on the circular guide rail 9. The linear guide rail 10 and the circular guide rail 9 provide guidance for the bidirectional rotating fork 11, ensuring that the bidirectional rotating fork 11 remains stable and does not deviate during its vertical movement. The first cable traction buckle 25 and the second cable traction buckle 28 are fixed to the gear mounting bracket 31 by the threads and nuts on the traction buckles.

[0102] Linear guide module 1 20 and linear guide module 29 are fixed to the upper and lower sides of module mounting frame 33, respectively. Fork 1 18 and fork 2 19 are telescopically mounted on the upper and lower sides of module mounting frame 33, respectively. Linear guide module 1 20 provides power for the extension and retraction of fork 18, and linear guide module 29 provides power for the extension and retraction of fork 2 19. The module mounting bracket 33 is equipped with fork linear guide rails 21 and fork circular guide rails 22 on both its upper and lower sides. Fork linear guide rail sliders 27 are slidably mounted on the fork linear guide rails 21, and fork circular guide rail sliders 26 are slidably mounted on the fork circular guide rails 22. The two sides of fork one 18 are connected to the fork linear guide rail sliders 27 and fork circular guide rail sliders 26 on the upper side of the module mounting bracket 33 via odd-shaped adapter blocks one 24 and two odd-shaped adapter blocks 23, respectively. The two sides of fork two 19 are also connected to the lower side of the module mounting bracket 33 via odd-shaped adapter blocks, respectively. The fork linear guide slider 27 and the fork circular guide slider 26 on the side are connected. In this way, the fork linear guide 21 and the fork circular guide rail 22 and their corresponding sliders provide further support and guidance for fork 18 and fork 29. The guiding accuracy of the fork linear guide 21 is higher than that of the fork circular guide rail 22. The installation arrangement of the fork linear guide 21 and the fork circular guide rail 22 can prevent the problem of stiffness caused by the deformation of fork 18 and fork 29 during the operation of linear guide module 1 20 and linear guide module 29.

[0103] Electromagnets 34 are installed on both fork 18 and fork 19. During use, the circuitry of the electromagnets 34 controls their attraction to the metal surfaces on both sides of the pallet, thus enabling the handling of the pallet and the goods on it. When handling a whole stack of pallets, fork 18 and / or fork 19 insert their concave portions into the lower part of the pallet, and the bidirectional rotating fork 11 moves the entire pallet upwards, supporting the lower edge of the whole stack of pallets, thereby achieving the transfer of the entire stack of pallets.

[0104] The bidirectional rotating fork 11 is rotatable and can move up and down. The two forks are retractable, making it suitable for picking up and placing goods in automated warehouses. Specifically, when in use, the servo motor 17 with a brake rotates, driving the left-hand winch 15 and the right-hand winch 14 to rotate and pull the two steel cables synchronously, thereby driving the bidirectional rotating fork 11 to move up and down. When the servo motor 32 rotates, it drives the external tooth rotating support gear 30 to rotate, thereby driving the module mounting frame 33 to rotate, thus driving the entire bidirectional rotating fork 11 to rotate. The linear guide module 1 20 provides power for the extension and retraction of the fork 18, and the linear guide module 29 provides power for the extension and retraction of the fork 2 19. By connecting the brake servo motor 17, servo motor 32, linear guide module 1 20, and linear guide module 2 29 to the controller, the controller can control the operation of the brake servo motor 17, servo motor 32, linear guide module 1 20, and linear guide module 2 29, which can stop the bidirectional rotating fork 11 at the required picking position in the automated warehouse, and control the extension and retraction of each fork to realize the picking and placing of pallets and goods on them.

[0105] The column stacker crane 1 adopts a two-way rotating fork design, which can meet the needs of handling goods on single pallets in the storage compartments of the automated warehouse, improving handling accuracy and operating efficiency. In addition, the combination design of linear guide rails and circular guide rails provides high-precision guidance for the forks, solving the problem of insufficient running accuracy of push-pull forks in the existing technology.

[0106] Please see Figure 19 , Figure 20 , Figure 21 , Figure 22 and Figure 23 In the short-stroke automated transit logistics warehouse of this utility model, the mixed picking and placing mechanism of the mixed picking and placing port 5 includes a lifting bracket, a lifting component and a telescopic component.

[0107] The lifting support includes a first lifting platform support frame 42, a second lifting platform support frame 59, a lifting platform mounting plate 43, and a slide mounting base 46.

A docking fork guide rail 55 is provided on the upper side of the telescopic module mounting base; the docking fork 52 is connected to the docking fork guide rail 55 via a slider. The docking fork guide rail 55 provides support and guidance for the extension and retraction of the docking fork 52. When the lifting servo motor 45 drives the sliding lifting plate 50 to move up and down along the lifting linear guide rail 54, it can drive the docking fork 52 to move up and down, adjusting the position of the docking fork 52.

[0112] An upper limit sensor 56 and a lower limit sensor 57 are provided on one side of the slide table mounting base 46. A metal sensor detection frame 58 is provided on the sliding lifting plate 50. The upper limit sensor 56 and the lower limit sensor 57 locate the origin, upper limit, and lower limit of the sliding lifting plate 50 by detecting the position of the metal sensor detection frame 58. One side of the slide table mounting base 46 is provided with two sensor mounting grooves, one above the other. The upper limit sensor 56 and the lower limit sensor 57 are respectively installed in the two sensor mounting grooves. The height of the limit sensors can be adjusted by adjusting the position of each limit sensor in the sensor mounting groove.

[0113] A camera 75 is mounted above the sliding lifting platform 50 via a camera mounting plate 76. The camera 75 is used to acquire the length, width, and height information of the goods on the pallet. The camera mounting plate 76 can be installed on the odd-shaped shelf 2.

[0114] Please see Figure 24 and Figure 25 In the short-stroke automated transit logistics warehouse of this utility model, the manual picking and placing mechanism of the manual picking and placing port 4 includes a manual picking and placing mechanism support frame 400 and a lifting bracket and lifting component installed on it. The structure of the lifting component of the manual picking and placing mechanism is the same as the structure of the lifting component of the mixed picking and placing mechanism. The lifting support of the manual loading and unloading mechanism includes a lifting platform mounting base plate 401, a lifting platform mounting frame 402, and a sliding platform mounting base plate 403. The lifting platform mounting base plate 401 is horizontally positioned and fixed to the top of the manual loading and unloading mechanism support frame 400. The bottom end of the lifting platform mounting frame 402 is fixed to the lifting platform mounting base plate 401. The sliding platform mounting base plate 403 is mounted on the lifting platform mounting frame 402 via adjusting bolts 44. The adjusting bolts 44 consist of internal screws and external bolts. The internal screws of the adjusting bolts 44 pass through the external bolts to fix the entire adjusting bolt to the lifting platform mounting frame 402. The sliding platform mounting base plate 403 is threadedly connected to the external bolts of the adjusting bolts 44. The verticality and tilt direction of the sliding platform mounting base plate 403 can be adjusted by rotating the external bolts of the adjusting bolts 44.

[0115] The lifting components of the manual loading and unloading mechanism include a sliding lifting plate 50, a lifting servo motor 45, a ball screw 47, and two lifting linear guides 54. The two lifting linear guides 54 are respectively located on both sides of the slide table mounting base 403. The two sides of the sliding lifting plate 50 are connected to the two lifting linear guides 54 via sliders. The lifting servo motor 45 is located at the top of the slide table mounting base 403. The output end of the lifting servo motor 45 is connected to the ball screw 47 via a coupling. The screw nut 48 on the ball screw 47 is connected to the sliding lifting plate 50 via a weighing sensor 49. Several pallet support positions 51 are arranged sequentially from top to bottom on the sliding lifting plate 50. The pallet support positions 51 are used to place pallets, and goods are placed on the pallets. In this embodiment, there are three pallet support positions from top to bottom.

[0116] The rotation of the lifting servo motor 45 drives the screw nut 48 on the ball screw 47 to move up and down, thereby driving the sliding lifting plate 50 to move up and down along the lifting linear guide rail 54. In use, the entire manual loading and unloading mechanism is located at the manual loading and unloading port 4, which is equipped with a lifting door 78 (see...). Figure 28 The weighing sensor 49 can weigh the pallet and the goods on it, and the lifting servo motor 45 can adjust the upper surface of the pallet to keep it level with the lower edge of the lifting door 78, making it convenient to pick up and put down goods.

[0117] The pallets on pallet support position 51 are stacked. When the pallets at the manual loading and unloading port 4 are used up, the column stacker crane 1 will pick up two stacks of pallets (each stack contains 5-10 pallets) from the pallet storage rack 3 and place them on the bottom pallet support position and the middle pallet support position. The servo motor 45 will rotate to drive the sliding lifting plate 50 to move, ensuring that the surface of the top pallet is level with the bottom edge of the lifting door 78.

[0118] An upper limit sensor 56 and a lower limit sensor 57 are installed on one side of the slide table mounting base 403. A metal sensor detection frame 58 is installed on the sliding lifting plate 50.

The upper limit sensor 56 and the lower limit sensor 57 are respectively installed in the two sensor mounting grooves. The height of the limit sensors can be adjusted by adjusting the position of each limit sensor in the sensor mounting groove.

[0119] A camera 75 is mounted above the sliding lifting platform 50 via a camera mounting plate 76. The camera 75 is used to acquire the length, width, and height information of the goods on the pallet. The camera mounting plate 76 can be installed on the odd-shaped shelf 2.

[0120] Please see Figure 26 and Figure 27 The short-stroke automated transit logistics warehouse of this utility model consists of a pallet storage rack 3 composed of a pallet support frame 41 and a pallet compartment 40. Several sets of pallet support bars 41 are arranged from top to bottom on the two opposite side walls of the pallet compartment 40. Each set of pallet support bars 41 is used to place two stacked pallets (the two stacks of pallets are arranged one in front of the other), with 5-10 pallets stacked in each stack.

[0121] Please see Figure 28 This utility model discloses a short-stroke automated transfer logistics warehouse. The odd-shaped rack 2 has an outer shell, making it more aesthetically pleasing and providing protection from sun and rain. A lifting door 78 is installed on the outside of the manual loading / unloading port 4, and a lifting door 80 is installed on the outside of the mixed loading / unloading port 5. A manual loading / unloading terminal 77 is installed above the lifting door 78 of the manual loading / unloading port 4, and a mixed loading / unloading terminal 79 is installed above the lifting door 80 of the mixed loading / unloading port 5. Both the manual loading / unloading terminal 77 and the mixed loading / unloading terminal 79 communicate with the column stacker crane 1. The manual loading / unloading terminal 77 communicates with the lifting servo motor 45 of the manual loading / unloading mechanism, and the mixed loading / unloading terminal 79 communicates with the lifting servo motor 45 and the telescopic module 53 of the mixed loading / unloading mechanism. The mixed loading / unloading terminal 79 can also communicate with the transfer equipment.

[0122] Please see Figure 29 and Figure 30 The short-stroke automated transit logistics warehouse of this utility model also includes a bulk cargo storage cabinet 82, a transfer equipment storage point 84, and a showroom / office hall 85. The bulk cargo storage cabinet 82 and the transfer equipment storage point 84 are located outside the odd-shaped shelving 2. The bulk cargo storage cabinet 82 is equipped with a bulk cargo storage terminal 83, which can communicate with the transfer equipment. The showroom / office hall 85 is located adjacent to the transfer equipment storage point 84, and the bulk cargo storage cabinet 82 is located in front of the transfer equipment storage point 84.

[0123] The short-stroke automated transit logistics warehouse of this utility model uses a manual pick-up and place logic for manual pick-up and place at manual pick-up and place port 4. The manual pick-up and place logic is as follows:

[0124] Manual loading / unloading logic: The manual loading / unloading terminal 77 acquires relevant information, such as facial information, QR code, phone number, account password, storage information, tracking number, and package delivery information. Then, it opens the lifting door 78, and the operator places the goods onto the pallet 60 of the pallet support position 51 on the sliding lifting platform 50. The camera 75 acquires the length, width, and height information of the goods and sends this information to the column stacker crane 1. The weighing sensor 49 acquires the weight information of the goods and sends it to the column stacker crane 1. The column stacker crane 1 matches the number of shelf compartments and the shelf height occupied by the goods based on their weight, length, width, and height information, and places the goods, along with the pallet carrying the goods, onto the matched pallet position on the odd-shaped shelf 2. Then, the lifting door 78 rises, completing the storage of the goods. Smaller goods occupy fewer compartments, and larger goods occupy more compartments; heavier goods are placed at lower shelf positions, and lighter goods are placed at higher shelf positions. This allows the storage height to be automatically adjusted according to the weight of the goods, avoiding the problem of excessive motor load on the column stacker crane 1 causing malfunction of the lifting system, thus improving work efficiency and safety.

[0125] Manual picking logic: The manual picking port terminal obtains relevant information, such as facial information, QR code, barcode, pickup number, phone number, account password, storage information, express delivery number, express pickup information, etc. The column stacker crane 1 matches the corresponding goods according to the relevant information obtained by the manual picking port terminal and takes the pallet carrying the goods along with the goods from the odd-shaped shelf 2 and places it on the pallet support position 51 of the sliding lifting plate 50. Then the lifting door 78 opens, and the person takes the goods from the manual picking port 4. The camera 75 detects whether the goods have been taken out. After confirming that the goods have been taken out, the lifting door 78 closes, and the goods are taken out.

[0126] The picking and placing logic of the mixed picking and placing port 5 includes both manual picking and placing logic and equipment picking and placing logic. The mixed picking and placing mechanism has both manual picking and placing functions. Its manual picking and placing logic is similar to that of the manual picking and placing port 4.

[0127] The logic for manual pickup and delivery is as follows:

[0128] Manual loading logic: The mixed loading / unloading terminal 79 acquires relevant information, such as facial information, QR code, phone number, account password, storage information, tracking number, and package delivery information. Then, it opens the lifting door 80, and the operator places the goods onto the pallet in the pallet support position 51 of the sliding lifting plate 50. The camera 75 acquires the length, width, and height of the goods and sends this information to the column stacker crane 1. The weighing sensor 49 acquires the weight of the goods and sends this information to the column stacker crane 1. The column stacker crane 1 matches the number of shelf compartments and the shelf height occupied by the goods based on their weight, length, width, and height, and places the goods, along with the pallet carrying them, onto the matched pallet position of the odd-shaped shelf 2. Then, the lifting door 80 rises, completing the storage of the goods. Smaller goods occupy fewer compartments, and larger goods occupy more compartments; heavier goods are placed at lower shelf positions, and lighter goods are placed at higher shelf positions.

[0129] Manual retrieval logic: The mixed retrieval terminal 79 obtains relevant information, such as facial information, QR code, barcode, pickup number, phone number, account password, storage information, courier number, and courier pickup information. The stacker crane 1 matches the corresponding goods according to the relevant information obtained by the mixed retrieval terminal 79 and removes the pallet carrying the goods along with the goods from the odd-shaped shelf 2 and places it on the pallet support position 51 of the sliding lifting plate 50. Then, the lifting door 80 opens, and the operator takes the goods from the mixed retrieval port 5. The camera 75 detects whether the goods have been taken out. After confirmation that the goods have been taken out, the lifting door 80 closes, completing the goods retrieval.

[0130] The equipment's pick-up and drop-off logic is as follows:

[0131] Equipment delivery logic: Transfer equipment (such as unmanned vehicles, AGVs, bulk transfer vehicles, etc.) acquires information (facial recognition, QR code, phone number, account password, storage information, tracking number, courier receipt information, weight, length, width, and height) of the goods at the receiving point (door-to-door pickup location, customer location, office, etc.) and the cargo logistics center (various express delivery warehousing and distribution centers, large logistics warehouses, etc.), and delivers the goods in batches to the mixed pickup and delivery port 5. After the mixed pickup and delivery port terminal 79 completes the information exchange, the lifting door 80 opens, and the equipment docking forks 52 extend to rotate. The goods are taken out of the transport equipment, the equipment docking forks 52 are retracted, and the pallet and the goods on it are brought into the mixed loading and unloading port 5. The column stacker crane 1 matches the number of racks and the height of the rack to be occupied by the goods according to the weight, length, width and height of the goods (small goods occupy fewer racks, large goods occupy more racks; heavy goods are placed at the lower position of the rack, and light goods are placed at the higher position of the rack) and places the goods along with the pallet carrying the goods into the pallet position of the matched odd-shaped rack 2. Then the lifting door 80 is closed, and the goods storage is completed.

[0132] Equipment picking logic: After the transfer equipment (unmanned vehicle, AGV, batch transfer vehicle, etc.) obtains relevant information (facial information, QR code, phone number, account password, storage information, courier number, courier receipt information, etc.) at the picking and placing terminal, the column stacker crane 1 matches the corresponding goods according to the relevant information obtained from the picking and placing terminal and takes the pallet carrying the goods along with the goods from the odd-shaped shelf 2 and places it on the equipment docking fork 52 of the mixed picking and placing port 5. The lifting door 80 opens, the equipment docking fork 52 extends to transfer the goods to the transfer equipment, the equipment docking fork 52 retracts, the lifting door closes, and the transfer equipment (unmanned vehicle, AGV, batch transfer vehicle, etc.) delivers the goods to the corresponding receiving point (door-to-door pickup location, customer location, office, etc.) and cargo logistics center (various express warehousing and operation centers, large logistics warehouses, etc.) according to the logistics information to complete the goods retrieval.

[0133] In this embodiment, there are three pallet support positions from top to bottom. When the inventory process occurs, the goods are placed on the pallet in the uppermost pallet support position 51. The forks on the column stacker crane 1 use electromagnets 34 to pick up the pallet along with the goods and place it on the odd-shaped shelf 2. The sliding lifting plate 50 rises so that the height of the new pallet surface is level with the lower end of the lifting door. If the inventory process continues, the pallets will decrease one by one. When the number of pallets decreases to the bottom pallet support position (there are three pallet support positions in total. When the three pallet support positions are idle, the bottom support position and the middle support position always keep pallets buffered), the column stacker crane 1 enters the pallet replenishment state. When there is no inventory or retrieval idle time, the column stacker crane 1 takes a stack of pallets from the pallet storage rack 3 and places it on the middle pallet support position of the retrieval port.

[0134] If the inventory process is delayed, the number of pallets will decrease gradually. Once all pallets have been retrieved, the stacker crane 1 will stop its retrieval and placement process and sequentially retrieve two stacks of pallets from the pallet storage rack 3, placing them on the bottom and middle pallet support positions at the retrieval and placement port. If the retrieval process is delayed, the number of pallets will increase gradually. When the number of pallets reaches the top pallet support position, the stacker crane 1 will enter the pallet retrieval state. When there is no inventory or retrieval idle time, the stacker crane 1 will retrieve pallets one by one from the top of the retrieval and placement mechanism. Pallets are placed on pallet storage rack 3 and stacked into a stack. If the picking process continues, the number of pallets will increase one by one. When the pallets are stacked to the highest position of the top pallet support, the column stacker crane 1 stops the picking and placing process and picks up the whole stack of pallets from the picking and placing port and places them on pallet storage rack 3. Each picking and placing mechanism has a weighing function. If a single item exceeds the weight limit by 15kg when it is stored (the upper limit of weight can be set as needed), the system will refuse to store the item, or the staff will store the overweight item in the bulk storage cabinet 82.

[0135] In actual use, manual pickup and delivery port 4 is mainly open to users, while mixed pickup and delivery port 5 is mainly open to administrators, couriers, etc.

[0136] Larger goods can be stored and retrieved in the large goods storage cabinet 82 by matching relevant information (facial information, QR code, phone number, account password, storage information, express number, express delivery information, etc.) at the large goods storage terminal 83. In this embodiment, the large goods storage cabinet 82 has multiple large cabinets, one of which is a terminal cabinet. The terminal cabinet mainly installs the components and maintenance tools of the large goods storage terminal 83. The other large cabinets are equipped with elastic magnetic locks. When retrieving goods, the magnetic locks can automatically pop out to open the door. After retrieving or storing goods, the door needs to be closed manually.

[0137] The transfer equipment parking point 84 can be used for idle parking and charging of transfer equipment, etc. The exhibition office 85 is used for the installation of logistics display screens, advertising screens, etc., and for administrator offices, etc.

[0138] AGVs (Automated Guided Vehicles) are the preferred choice for transfer equipment. Currently, the most common applications include AGV handling robots or AGV carts, primarily used for automated logistics and material handling. AGV handling robots automatically transport goods to designated locations using special landmark navigation. The most common guidance methods are magnetic strip guidance and laser guidance. Currently, the most advanced and scalable method is UHF RFID guidance developed by Microlink Technology. Magnetic strip guidance is the most common and lowest-cost method, but it has limitations in site setup and can affect the overall decor. Laser guidance is the most expensive and has high site requirements, so it is generally not used. RFID guidance has a moderate cost, and its advantages include high guidance accuracy, easier site setup to accommodate even the most complex site layouts, no impact on the overall environment, and high security and stability that magnetic strip and laser navigation lack.

[0139] This utility model discloses a short-stroke automated transfer logistics warehouse. The irregularly shaped racks allow for the transfer and storage of goods of various sizes, enabling mixed storage of goods of different sizes and improving warehouse space utilization. The column stacker crane adopts a bidirectional rotating fork design, which can meet the needs of handling single pallets of goods within the racks, improving handling accuracy and operational efficiency. Furthermore, the combination of linear guide rails and circular guide rails provides high-precision guidance for the forks, solving the problem of insufficient accuracy in the operation of push-pull forks in existing technologies. The picking and placing mechanism can be used for the retrieval and storage of goods within the irregularly shaped racks, working in conjunction with the racks, column stacker crane, and transfer equipment to achieve automatic transfer, storage, and picking of goods. The picking and placing mechanism is equipped with a weighing sensor, which can automatically adjust the storage height according to the weight of the goods, avoiding the problem of excessive motor load on the column stacker crane leading to lifting system failure, thus improving work efficiency and safety.

[0140] In summary, this utility model's short-stroke automated transit logistics warehouse can realize the transit and storage of goods of various sizes, and can realize the automatic outbound and inbound of goods. It can be used in conjunction with unmanned vehicles, AGVs and other transfer equipment to realize the transit of goods.
