Description

Technical Field

[0001] This invention relates to the technical field of automated storage and retrieval systems (AS / RS), and particularly to an intelligent overhead conveyor scheduling device for an automated AS / RS. Background Technology

[0002] As the core carrier of modern logistics warehousing system, automated storage and retrieval systems (AS / RS) rely on three-dimensional warehousing layout, automated handling equipment and intelligent scheduling system to greatly improve the utilization rate of warehousing space and the efficiency of material flow. They have been widely used in many industries such as manufacturing, e-commerce, pharmaceuticals, and cold chain.

[0003] For example, Chinese patent CN104986492A discloses a picking and scheduling device for a logistics warehouse, including two C-shaped guide rails and a trolley between them. The trolley has two wheels on each side, and the wheels are located inside the C-shaped guide rails. A rotatable basket is suspended below the trolley. One of the C-shaped guide rails has a series of small holes evenly distributed on its side, and all the small holes form a straight line parallel to the C-shaped guide rail. The trolley is also equipped with an infrared emitter and an infrared receiver, which are located on both sides of the C-shaped guide rail with small holes. The infrared emitter, infrared receiver, and small holes are at the same height. The trolley is positioned by counting the number of light signals received by the infrared receiver. Since the spacing between the small holes on the guide rail can be made relatively small, the trolley can be accurately positioned.

[0004] However, the aforementioned scheduling device still has some shortcomings in actual use: 1. Existing carriers mostly use a single hook type for bearing, lacking flexible limiting and adaptive adjustment mechanisms. For irregular, fragile or heavy materials, problems such as unstable suspension, shaking and falling off during transportation are likely to occur. This not only causes material loss, but may also lead to safety accidents such as equipment jamming and derailment.

[0005] 2. Secondly, in the existing technology, when multiple carriers operate in parallel, there is a lack of accurate identification, docking and stable locking mechanisms. Only a single carrier can be used for independent transportation. For large batches and large volumes of materials, multiple round trips are required, which is inefficient. In addition, the independent driving of each carrier leads to high energy consumption. At the same time, scheduling disorder problems such as path conflicts and congestion are prone to occur.

[0006] 3. In addition, most existing technologies rely on manual assistance for unloading materials, which not only increases manpower input, but the randomness of manual operation also easily leads to material collisions and damage. In particular, the timing of unloading is difficult to seamlessly connect with warehouse sorting, packaging and other links, which can easily lead to errors in material classification and affect the overall circulation efficiency.

[0007] Therefore, based on the above-stated viewpoints, there is still room for improvement in existing intelligent overhead conveyor scheduling devices for warehouses. Summary of the Invention

[0008] To address the aforementioned problems, this invention provides an intelligent overhead conveyor scheduling device for automated storage and retrieval systems, employing the following technical solution: An intelligent overhead conveying scheduling device for an automated three-dimensional warehouse includes a conveying guide rail system and an overhead carrier mounted on the conveying guide rail system. The suspended carrier includes a drive block and a load-bearing component mounted on the bottom of the drive block; The load-bearing components include a main load-bearing hook, a secondary load-bearing hook, a load-bearing column, and a limiting rod. The main load-bearing hook is connected to the bottom of the drive block. The secondary load-bearing hook is rotatably installed on the side of the main load-bearing hook away from the drive block via the load-bearing column. The loading and unloading of materials can be achieved by adjusting the angle of the secondary load-bearing hook. The middle part of the limiting rod is rotatably mounted on the side wall of the main carrying hook via a torsion spring, and the limiting rod is inclined and intersects with the secondary carrying hook to limit the material suspended on the secondary carrying hook; The conveying guide system includes a fixed frame, a conveying guide rail, and branch guide rails. The conveying guide rail is in the shape of a ring, with several branch guide rails at its ends. Both the conveying guide rail and the branch guide rails are mounted on the fixed frame, and a material drop area is provided at the branch guide rails.

[0009] Preferably, the drive block is equipped with a control motor that connects to the conveying guide rail and the branch guide rail and controls the movement of the drive block.

[0010] Preferably, a telescopic rod is slidably sleeved on the side of the limiting rod that is close to the bearing hook, and a return spring is provided between the telescopic rod and the limiting rod.

[0011] Preferably, an automatic unhooking component is provided at the connection between the secondary hook and the main hook. The automatic unhooking component includes a linkage gear installed at both ends of the support column, a linkage rack meshing on the linkage gear, the linkage rack slidingly disposed on the side wall of the secondary hook, and a feeding frame connected to the linkage rack slidingly disposed on the secondary hook. The linkage gear is also equipped with a control rack, which is slidably mounted on the side wall of the main hook, and a control spring is provided between the control rack and the main hook.

[0012] Preferably, a first electrically controlled push rod and a second electrically controlled push rod are installed on the fixed frame located in the branch guide rail unloading area. The first electrically controlled push rod is equipped with an opening and closing plate that squeezes the limit rod to open and close the bearing secondary hook. The second electrically controlled push rod is equipped with an execution plate that drives the control rack to move, thereby rotating the bearing secondary hook.

[0013] Preferably, the drive block is also equipped with an intelligent identification and locking unit. The intelligent identification and locking unit includes an intelligent locking plate that enables the connection of several suspended carriers. One side of the intelligent locking plate is integrated with an identification insert, and the other side is provided with an identification slot corresponding to the identification insert. In addition, the intelligent locking plate is also equipped with several model sensing buttons of different types.

[0014] Preferably, one side of the top of the intelligent locking plate is provided with a metal plate, and the other side is provided with an adsorption magnet to be powered on. After the adsorption magnet is powered on, it can adsorb and lock the metal plate on the adjacent intelligent locking plate.

[0015] Preferably, a linkage spring is installed on one side of the adsorption magnet. The end of the linkage spring away from the adsorption magnet is installed on the intelligent locking plate through a connecting frame. An insulating rope is also connected to the adsorption magnet. One end of the insulating rope slides through the connecting frame and is connected to the end of the limit rod away from the load-bearing sub-hook.

[0016] Preferably, the side wall of the drive block is also provided with a protector, which includes a storage tank for storing gas and an isolation airbag for isolating and protecting the material. The isolation airbag is connected to the storage tank, and after the gas in the storage tank enters the isolation airbag, the isolation airbag unfolds and is located between adjacent suspended carriers to prevent collisions between materials when the suspended carriers approach each other.

[0017] Preferably, the limiting rod is also provided with a linkage rope, and the end of the linkage rope away from the limiting rod is connected to a locking rack. The locking rack is slidably mounted on the side wall of the main hook through the traction column, and a traction spring is provided between the locking rack and the main hook.

[0018] In summary, this application includes at least one of the following beneficial technical effects: I. This invention forms a closed, flexible limiting space through the coordinated design of the main and auxiliary hooks of the load-bearing components, the limiting rod, and the telescopic rod, which prevents materials from falling off during the conveying process. At the same time, it is adaptable to materials of different specifications and shapes, thus improving the load-bearing adaptability.

[0019] Second, this invention relies on an intelligent identification and locking unit to achieve precise docking, stable locking and collaborative operation of multiple suspended carriers. The carriers can be flexibly combined according to material requirements, which can not only improve the conveying efficiency of large batches and large volumes of materials, but also save energy by controlling the motor by shutting down the intermediate carriers.

[0020] Third, the integration of the automatic unhooking component and the electrically controlled push rod in this invention enables automated material feeding without manual intervention, reducing labor costs and avoiding material damage and safety hazards caused by manual operation. The setting of the protector and buffer pad effectively prevents material collisions between adjacent carriers, reduces equipment wear and material damage, and extends the service life of the device.

[0033] The following combination Figures 1-10 This application will be described in further detail.

[0034] This invention provides an intelligent suspended conveyor scheduling device for automated storage and retrieval systems (AS / RS). It establishes an intelligent branch track system, integrates an automatic unhooking execution unit, and adds an intelligent identification and locking module and material protection components. This solves the technical problems of existing devices, such as easy detachment of loads, low scheduling efficiency, weak collaborative operation capability, and easy damage to materials. It realizes intelligent, automated, and stable operation of the entire suspended conveyor process, and improves the efficiency and safety of material flow in automated storage and retrieval systems.

[0035] Reference Figure 1 As shown, an intelligent suspended conveying scheduling device for an automated three-dimensional warehouse includes a conveying guide rail system 1 and several suspended carriers 2 mounted on the conveying guide rail system 1.

[0036] The conveyor rail system 1 serves as the operating carrier for the suspended transporter 2. It adopts a modular layout, facilitating adjustments and expansion based on the actual layout of the automated warehouse. Specifically, it includes a fixed frame 10, conveyor rails 11, and branch rails 12. One side of the conveyor rails 11 is located within the automated warehouse, serving as a placement area for materials. The intersection of the conveyor rails 11 and the branch rails 12 allows for the categorized storage of materials within the warehouse, serving as a discharge area.

[0037] First, when multiple materials are needed in the automated warehouse, the equipment in the warehouse places the materials on the suspended carrier 2 on the conveying guide rail 11. The suspended carrier 2 moves along the conveying guide rail 11 to the corresponding branch guide rail 12 to unload the materials, so that they fall to the designated position in the dropping area, thus completing the intelligent scheduling of materials.

[0038] Among them, the suspended carrier 2 is the core actuator for material carrying and movement in this device.

[0039] Reference Figure 2 and Figure 3 As shown, the suspended carrier 2 includes a drive block 20 and a carrier component 21 installed at the bottom of the drive block 20. The drive block 20 serves as the power and control core of the suspended carrier 2 and is directly connected to the conveying guide rail system 1. It controls the carrier component 21 to move stably along the conveying guide rail system 1 through its own power output. The carrier component 21 directly undertakes the function of suspending and bearing materials, thereby realizing the stable hanging and precise loading and unloading of materials.

[0040] In addition, a control motor 13 is also installed on the drive block 20, which is connected to the conveying guide rail 11 and the branch guide rail 12 and controls the movement of the drive block 20 by electric connection.

[0041] The control motor 13 is a known existing structure. As the core power source of the drive block 20, it adopts an independent electric control drive mode and can adjust the running speed, start-stop status and track-changing action of the drive block 20 in real time according to the scheduling instructions, so as to ensure that the drive block 20 runs accurately along the designated guide rail path.

[0042] Reference Figure 3 , Figure 4 and Figure 5 As shown, the carrier component 21, as the direct material carrier component, specifically includes a main carrier hook 210, a secondary carrier hook 211, a carrier column 212, and a limiting rod 213. The main carrier hook 210 serves as the main support structure of the carrier component 21, with its top end fixedly connected to the bottom of the drive block 20. The secondary carrier hook 211 is rotatably mounted on the side of the main carrier hook 210 away from the drive block 20 via the carrier column 212. The secondary carrier hook 211 can freely adjust its angle with the carrier column 212 as the rotation center. By adaptively adjusting the tilt angle and opening and closing angle of the secondary carrier hook 211, it can adapt to the suspension and loading requirements of materials of different specifications and shapes. At the same time, it can precisely coordinate with the unloading action to achieve smooth material release and avoid jamming and damage.

[0043] The limiting rod 213 is rotatably mounted on the side wall of the main carrying hook 210 via a torsion spring. The torsion spring provides a continuous elastic restoring force to the limiting rod 213, so that the limiting rod 213 always maintains the preset inclined distribution state. The inclined limiting rod 213 and the secondary carrying hook 211 form a cross layout. The cross area between the two forms a closed material limiting space, which flexibly limits the material suspended on the secondary carrying hook 211 in all directions, preventing the material from falling off during the conveying process.

[0044] Reference Figure 4 , Figure 5 and Figure 6 As shown, a telescopic rod 214 is slidably sleeved on the side of the limiting rod 213 that is close to the bearing hook 211. A return spring 215 is provided between the telescopic rod 214 and the limiting rod 213. The return spring 215 provides elastic telescopic force for the telescopic rod 214. When the bearing member 21 is located in the material placement area, the telescopic rod 214 slides along the limiting rod 213. At this time, the telescopic rod 214 can be moved away from the bearing hook 211. At this time, the bearing hook 211 is opened, and the material can be installed (such as hanging up a plastic bag or hook). Then the telescopic rod 214 is released, and the telescopic rod 214 and the limiting rod 213 cross the bearing hook 211 again to limit the material.

[0045] When the material is conveyed to the discharge area, refer to Figure 5As shown, the drive block 20 is also equipped with an intelligent identification and locking unit 4. As the core module for realizing the collaborative operation of multiple suspended carriers 2, the intelligent identification and locking unit 4 can complete the accurate identification, automatic connection and stable locking between the suspended carriers 2. Specifically, it includes an intelligent locking plate 40 that connects several suspended carriers 2. One side of the intelligent locking plate 40 is integrated with an identification insert 41, and the other side is provided with an identification slot 42 corresponding to the identification insert 41. The identification inserts 41 and identification slots 42 of adjacent suspended carriers 2 are inserted and matched with each other to realize the accurate positioning and docking between the suspended carriers 2 and avoid connection misalignment.

[0046] The intelligent locking plate 40 is also equipped with several different types of model sensing buttons 43. The model sensing buttons 43 can automatically identify the specifications and type information of the material being carried and transmit the identification signal to the scheduling system to provide data support for intelligent diversion and accurate storage. Different models of model sensing buttons 43 correspond to different specifications of materials, with high identification accuracy and fast response speed.

[0047] It should be noted that, referring to Figure 5 As shown, there are multiple sets of model sensor buttons 43. Pressing the corresponding model sensor buttons 43 on multiple suspended carriers 2 can ensure that multiple suspended carriers 2 can be quickly connected in the future, ensuring that multiple materials in the same order form a whole. This not only facilitates transportation, but also prevents the subsequent problem of material misplacement.

[0048] In practice, after the material is loaded, the limiting rod 213 maintains a preset tilt state under the elastic force of the torsion spring, forming a cross-limiting space with the bearing hook 211. The telescopic rod 214 extends under the action of the return spring 215, fits against the surface of the material, and provides all-round flexible limiting of the material.

[0049] After receiving the identification signal from the model sensor button 43, the scheduling system sends a control command to the control motor 13 of the drive block 20. The control motor 13 starts and drives the drive block 20 to move stably along the conveying guide rail 11. The moving speed is adaptively adjusted according to the weight, type and conveying distance of the material to ensure smooth movement without violent shaking.

[0050] When the suspended carrier 2 moves to the junction of the conveying guide rail 11 and the branch guide rail 12, the scheduling system sends a track-changing command according to the preset conveying path, controlling the motor 13 to adjust the running direction of the drive block 20, driving the suspended carrier 2 to move along the corresponding branch guide rail 12, realizing intelligent classification and diversion of materials. During the track-changing process, the drive block 20 and the branch guide rail 12 cooperate smoothly without jamming or derailment. The moving speed of the suspended carrier 2 slows down to ensure accurate track changing. After the track changing is completed, the control motor 13 returns to the preset speed and continues to move along the branch guide rail 12 towards the dropping area.

[0051] For example, when the system in the automated warehouse receives an order requiring three items, and these three items are located in different parts of the warehouse, sending all three items out at once would require locating all three items, packing them together, and transporting them via the overhead conveyor 2. This is not only inefficient but also time-consuming, especially when the three items are of different sizes. If the three items are large, one overhead conveyor 2 cannot handle them.

[0052] Therefore, after obtaining a material, this application can place it on the suspended carrier 2 and press the model sensor button 43. At this time, the suspended carrier 2 is given a signal to tell the suspended carrier 2 that there is a material suspended on it, but there is still material that has not been conveyed. The material is conveyed first, and the material is placed in the dropping area after all the subsequent materials are complete.

[0053] Therefore, after the first material is conveyed, the second material will also be conveyed after it is obtained, and the third material will be conveyed last. At this time, all three materials are on the conveying guide rail 11. The information provided by the model sensor button 43 of the second and third materials is obtained by the control motor 13, which automatically controls the conveying speed to catch up with the first material. This ensures that the three materials are connected through the intelligent identification locking unit 4. After the suspension carriers 2 of the three materials are connected, the control motor 13 located in the middle can stop working to save energy. The control motors 13 at the beginning and end of the whole formed by the connection of multiple suspension carriers 2 can control the material. This not only does not affect the material conveying, but also reduces the excess energy consumption until the whole formed by the connection of multiple suspension carriers 2 reaches the dropping area.

[0054] If the second or third material takes a long time to acquire, and the first material has already arrived at the dropping area, the suspended carrier 2 of the first material will wait on one of the designated branch tracks, and lock and drop together after the other materials arrive.

[0055] In summary, during the conveying process, the intelligent scheduling system (known structure) monitors the operating status of the suspended carrier 2 in real time, receives signal feedback from components such as the control motor 13 and model sensor button 43, and adjusts the operating speed and path of the suspended carrier 2 in a timely manner to avoid path conflicts and congestion when multiple suspended carriers 2 operate in parallel, ensuring that materials can be quickly and accurately conveyed to the designated unloading area.

[0056] Reference Figure 5 , Figure 6 and Figure 7As shown, the limiting rod 213 is also provided with a linkage rope 80. The end of the linkage rope 80 away from the limiting rod 213 is connected to a locking rack 81. The locking rack 81 is slidably mounted on the side wall of the main carrying hook 210 via the traction column 82. A traction spring 83 is provided between the locking rack 81 and the main carrying hook 210.

[0057] In the initial state, the traction spring 83 presses down on the locking rack 81, causing the locking rack 81 to press against the linkage gear 30, thus limiting the linkage gear 30. In this way, when the load-bearing auxiliary hook 211 is loaded with materials, it can withstand heavier and larger volumes, preventing the load-bearing auxiliary hook 211 from reversing from the hinge due to excessive weight of the materials.

[0058] The traction column 82 pulls the locking rack 81 to ensure that the locking rack 81 can move along the specified trajectory, thereby improving the safety of the meshing between the locking rack 81 and the linkage gear 30.

[0059] Reference Figure 5 , Figure 8 and Figure 9 As shown, a metal plate 44 is provided on one side of the top of the intelligent locking plate 40, and an adsorption magnet 45 to be powered on is provided on the other side. After the adsorption magnet 45 is powered on, it can be connected to the metal plate 44 at the adsorption connection position to realize the connection and locking of several suspended carriers 2.

[0060] A linkage spring 46 is installed on one side of the adsorption magnet 45. The end of the linkage spring 46 away from the adsorption magnet 45 is installed on the intelligent locking plate 40 through the connecting bracket. An insulating rope 47 is also connected to the adsorption magnet 45. One end of the insulating rope 47 slides through the connecting bracket and is connected to the end of the limit rod 213 away from the bearing hook 211.

[0061] During operation, when large quantities and volumes of materials need to be transported, the intelligent scheduling system controls multiple suspended carriers 2 to work together. The scheduling system determines the number of suspended carriers 2 participating in the collaborative operation based on the total amount and specifications of the materials, and controls each suspended carrier 2 to move to the designated docking position. Adjacent suspended carriers 2 are precisely connected and docked through the identification insert 41 and identification slot 42 of the intelligent locking plate 40. During the docking process, the buffer pad provides flexible cushioning to reduce collision and wear during the docking, ensuring accurate and firm docking.

[0062] Simultaneously, after docking is completed, the scheduling system sends a locking command to control the adsorption magnets 45 of each suspended carrier 2 to be energized. The adsorption magnets 45 generate a strong magnetic attraction force, which tightly adsorbs and connects with the metal plate 44 on the intelligent locking plate 40 of the adjacent suspended carrier 2, realizing the stable locking of multiple suspended carriers 2. After locking, the suspended carriers 2 form a whole, synchronously receive the control command of the scheduling system, and move along the designated guide rail path, improving the conveying efficiency of large batches of materials.

[0063] After the multiple suspended carriers 2 work together to transport materials to the designated unloading area, the materials are unloaded according to the above-mentioned precise unloading process. After unloading, the scheduling system sends an unlocking command to control the power off of the adsorption magnet 45. Under the elastic restoring force of the linkage spring 46, the adsorption magnet 45 separates from the metal plate 44. At the same time, if the limit rod 213 is in a rotating state, it will assist in pulling the adsorption magnet 45 through the insulating rope 47 to ensure complete unlocking. After unlocking, each suspended carrier 2 separates from each other and, under the control of the scheduling system, returns to its initial position or performs the next round of collaborative operation tasks, flexibly adapting to different operation requirements.

[0064] Reference Figure 4 and Figure 8 As shown, an automatic unhooking component 3 is provided at the connection between the secondary hook 211 and the main hook 210. The automatic unhooking component 3 is the core execution structure for realizing automated material feeding, and can complete the rotation opening and closing of the secondary hook 211 and the material detachment without manual intervention.

[0065] Specifically, it includes linkage gears 30 installed at both ends of the bearing column 212. The linkage gears 30 rotate synchronously with the bearing column 212. A linkage rack 31 meshes with the linkage gears 30. A feeding frame 32 is slidably sleeved on the bearing auxiliary hook 211 at one end of the linkage rack 31. The feeding frame 32 is in direct contact with the material. When the linkage rack 31 moves, it drives the feeding frame 32 to move, so that the feeding frame 32 can easily push the material hanging on the bearing auxiliary hook 211 off, realizing the stable feeding of the material on the bearing auxiliary hook 211.

[0066] The linkage gear 30 is also equipped with a control rack 33, which is slidably mounted on the side wall of the main carrying hook 210. A control spring 34 is provided between the control rack 33 and the main carrying hook 210. The control spring 34 provides elastic restoring force to the control rack 33. The rotation angle of the linkage gear 30 is controlled by the sliding of the control rack 33, thereby controlling the rotation state of the secondary carrying hook 211 and avoiding accidental disengagement.

[0067] Reference Figure 8 and Figure 9 As shown, a first electrically controlled push rod 35 and a second electrically controlled push rod 36 are installed on the fixed frame 10 located in the material feeding area of ​​the branch guide rail 12. The first electrically controlled push rod 35 and the second electrically controlled push rod 36 serve as the core execution units of the material feeding area. They move synchronously or stepwise according to the scheduling instructions. An opening and closing plate 37 is installed on the first electrically controlled push rod 35. The opening and closing plate 37 moves telescopically under the drive of the first electrically controlled push rod 35. During the movement, it directionally squeezes the limiting rod 213, overcomes the elastic force of the torsion spring, drives the limiting rod 213 to rotate, releases the limiting rod 213 from the limiting constraint of the material, and enables the bearing secondary hook 211 to open and close for material feeding.

[0068] An actuator plate 38 is installed on the second electric control push rod 36. The actuator plate 38 moves in a direction under the drive of the second electric control push rod 36. During the movement, it directly drives the control rack 33 to slide, overcomes the elastic force of the control spring 34 to release the lock on the linkage gear 30, and then allows the bearing secondary hook 211 to rotate freely to complete the unloading action. The action sequence of the first electric control push rod 35 and the second electric control push rod 36 is uniformly controlled by the intelligent scheduling system to achieve seamless connection of limit release and hook unloading.

[0069] Reference Figure 10 As shown, a protector 5 is also provided on the side wall of the drive block 20. As the core component of material safety protection, the protector 5 can effectively prevent collisions between materials when adjacent suspended carriers 2 are close. Specifically, it includes a storage tank 6 for storing gas and an isolation airbag 7 for isolating and protecting materials. The storage tank 6 is fixed to the side wall of the drive block 20 and pre-stores compressed protective gas inside. The isolation airbag 7 is connected to the storage tank 6. After the gas in the storage tank 6 enters the isolation airbag 7, the isolation airbag 7 quickly inflates and unfolds. The unfolded isolation airbag 7 is located between adjacent suspended carriers 2, forming a flexible protective barrier, blocking direct contact between materials, buffering the impact force of collisions, and protecting the safety of materials and equipment.

[0070] The intelligent locking plate 40 has a buffer pad at the identification insert 41 and identification slot 42. The buffer pad is made of flexible and wear-resistant material. It provides flexible buffer during the docking and locking process of the suspended carrier 2, reduces the collision and wear of the insertion, and improves the connection stability and service life of the equipment.

[0071] During operation: First, the material to be transported is suspended and mounted on the bearing hook 211 of the suspension carrier 2. During the mounting process, ensure that the material is securely suspended.

[0072] Step 2: After receiving the identification signal from the model sensor button 43, the scheduling system sends a control command to the control motor 13 of the drive block 20. The control motor 13 starts and drives the drive block 20 to move stably along the conveying guide rail 11. The moving speed is adaptively adjusted according to the weight, type and conveying distance of the material to ensure smooth movement.

[0073] Step 3: When the suspended carrier 2 moves to the docking point of the conveying guide rail 11 and the branch guide rail 12, the scheduling system sends a track change command according to the preset conveying path, controls the motor 13 to adjust the running direction of the drive block 20, and drives the suspended carrier 2 to move along the corresponding branch guide rail 12 to realize intelligent classification and diversion of materials.

[0074] Step 4: When the suspended carrier 2 moves to the unloading area of ​​the branch guide rail 12, the scheduling system sends a positioning command to control the motor 13 to stop running. The suspended carrier 2 is precisely positioned at the designated position in the unloading area and is precisely aligned with the unloading station. Subsequently, the first electric control push rod 35 drives the opening and closing plate 37 to extend the directional extrusion limit rod 213, which drives the limit rod 213 to rotate around the rotation point, so that the limit rod 213 and the bearing auxiliary hook 211 are disengaged from the cross state, and the limit rod 213 is released from the limiting constraint on the material.

[0075] After the control rack 33 is released from locking, the bearing hook 211 rotates around the bearing column 212 and gradually unfolds. Under the action of gravity, the material smoothly leaves the bearing hook 211 and falls into the designated station in the unloading area, completing the automated unloading operation.

[0076] Step 5: When large quantities and volumes of materials need to be transported, the intelligent scheduling system controls multiple suspended carriers 2 to work together. Adjacent suspended carriers 2 are precisely connected and docked through the identification inserts 41 and identification slots 42 of the intelligent locking plate 40. After docking, the scheduling system sends a locking command to control the adsorption magnets 45 of each suspended carrier 2 to be energized. The adsorption magnets 45 generate a strong magnetic attraction force and are tightly adsorbed and connected to the metal plates 44 on the intelligent locking plates 40 of the adjacent suspended carriers 2, so as to achieve stable locking of multiple suspended carriers 2. After locking, the suspended carriers 2 form a whole, synchronously receive the control commands of the scheduling system, and move along the designated guide rail path.

[0077] Step 6: After the multiple suspended carriers 2 work together to transport the material to the designated unloading area, the material is unloaded according to the above-mentioned precise unloading process. After the unloading is completed, the scheduling system sends an unlocking command to control the power off of the adsorption magnet 45. Under the elastic restoring force of the linkage spring 46, the adsorption magnet 45 separates from the metal plate 44. At the same time, if the limit rod 213 is in a rotating state, it will assist in pulling the adsorption magnet 45 through the insulating rope 47 to ensure complete unlocking. After unlocking, each suspended carrier 2 separates from each other and, under the control of the scheduling system, returns to its initial position or performs the next round of collaborative operation tasks, flexibly adapting to different operation requirements.

Therefore, all equivalent changes made in accordance with the structure, shape, and principle of the present invention should be covered within the scope of protection of the present invention.
