Description

Technical Field

[0001] This invention relates to the field of cargo storage and handling equipment. Background Technology

[0002] In automated warehousing and logistics systems, shuttle cars are used in conjunction with elevators for cargo transfer and retrieval operations. Existing technologies typically employ elevators that occupy a large space, requiring separate installation and thus not suitable for integration into automated racking systems.

[0003] Shuttle car locking typically employs a cylinder-driven stop mechanism installed on the lifting platform, or individual blocking devices installed on each shelf level, with unlocking triggered by sensor detection of positioning. Using cylinder-driven or electrically driven stop structures requires additional response time to raise and lower the stop, extending the overall handling process and reducing efficiency. Furthermore, during rapid cargo handling, the shuttle car's vibrations during rapid ascent and descent with the elevator can cause collisions with the stop, resulting in cargo displacement, falling, or damage, and the shuttle car itself may also be damaged in the collision. Summary of the Invention

[0004] Purpose of the invention: In order to overcome the shortcomings of the existing technology, the present invention provides an embedded lifting storage system and its working method. By embedding the lifting machine into the three-dimensional rack and setting a locking actuator and an unlocking drive mechanism, space is saved and the efficiency of inbound and outbound operations is improved. The shuttle car on it automatically unlocks and passes through when it is raised and lowered and automatically locks and stops when it leaves.

[0005] Technical Solution: To achieve the above objectives, the present invention provides an embedded lifting storage system, comprising: a shelf, an embedded lifting mechanism, and a shuttle; the embedded lifting mechanism is disposed on one side of the shelf and includes a vertical guide frame, a lifting platform, and a drive mechanism for driving the lifting platform to move up and down along the vertical guide frame; the shuttle is horizontally positioned on the lifting platform; the shelf includes several layers of horizontally extending goods placement channels, and each goods placement channel is provided with a pair of traveling guide rails at its lower part;

[0006] When the lifting platform is raised to the height of any cargo placement channel, the lifting platform docks with a pair of trolley rails at the same height, and the shuttle can travel from the lifting platform to the pair of trolley rails docked with the lifting platform; the vertical guide frame extends in the Y direction, and the two trolley rails extend in the X direction.

[0007] The embedded lifting machine is equipped with a locking system. When the locking system is in the locked state, the X-direction of the shuttle on the lifting platform is locked by the locking system. When the lifting platform is raised to the height of any cargo placement channel and docks with a pair of traveling rails at the same height, the locking system automatically unlocks.

[0008] Furthermore, the locking system on the lifting platform includes a B locking actuator and a B unlocking drive mechanism, which are installed at intervals on the lifting platform. The embedded lifting machine is equipped with a pair of bracket beams for each of the horizontally extending cargo placement channels on several layers of the shelf. The locking system on the bracket beams includes an A locking actuator and an A unlocking drive mechanism, which are installed at intervals on the bracket beams. The B unlocking drive mechanism corresponds to the A locking actuator in the Y direction, and the A unlocking drive mechanism corresponds to the B locking actuator in the Y direction. When the lifting platform rises and falls to the target layer in the Y direction, the B unlocking drive mechanism touches the A locking actuator, and simultaneously the A unlocking drive mechanism touches the B locking actuator, causing the A locking actuator and the B locking actuator to synchronously switch from a limited-position state to a passable state.

[0009] Furthermore, both the A locking actuator and the B locking actuator include a limiting end, a counterweight end, and a collision block; both the A locking actuator and the B locking actuator are mounted on the mounting base of the bracket beam and the lifting platform respectively via a rotating shaft, and rotate around the rotating shaft under the contact action of the corresponding unlocking drive mechanism; magnets are provided on the side of the mounting base near the counterweight end and the side of the counterweight end near the mounting base, and magnets are also provided on the limiting end and the counterweight end.

[0010] Furthermore, the magnet on the side of the mounting base near the counterweight end has opposite polarities to the magnet on the side of the counterweight end near the mounting base. When they approach each other, they generate an attraction force, so that when the A locking actuator and the B locking actuator are in the limited position, they rely on their own gravity and magnetic attraction force to keep the limited end part facing upward, so as to prevent the shuttle car from moving.

[0011] Furthermore, the magnets on locking mechanism A and locking mechanism B have opposite polarities. When they approach each other, they attract each other, thus restraining the swing amplitude of locking mechanisms A and B caused by collision inertia and assisting them in resetting. When they move away from each other, locking mechanisms A and B quickly reset to their limit positions under their own gravity and the attraction force.

[0012] Furthermore, the A unlocking drive mechanism and the B unlocking drive mechanism each include an upper arc surface and a lower arc surface; the collision block includes an upper arc surface and a lower arc surface; when the lifting platform descends from top to bottom along the Y direction to the target layer, the lower arc surface of the collision wheel assembly contacts the upper arc surface of the collision block, and the lower arc surface and the upper arc surface remain tangent during the contact process to guide the corresponding locking actuator to switch from the limit state to the pass state; when the lifting platform rises from bottom to top along the Y direction to the target layer, the upper arc surface of the A unlocking drive mechanism and the B unlocking drive mechanism contacts the lower arc surface of the collision block, and the upper arc surface and the lower arc surface remain tangent during the contact process to guide the corresponding locking actuator to switch from the limit state to the pass state.

[0013] Furthermore, the shuttle has a lifting platform supporting a cargo pallet, on which cargo is supported. The shuttle travels between a pair of guide rails. The cargo pallet is wider than the width between the two guide rails. When the cargo pallet and its cargo are stored at any position in the cargo placement channel, the cargo pallet is horizontally mounted on the upper side of the two guide rails. The lifting platform can move up and down along the Y direction on the shuttle to lift the cargo pallet from the shuttle or lower the cargo pallet onto the shuttle.

[0014] Furthermore, the vertical guide frame is constructed using the uprights of the shelving unit, and the bottom of the embedded lifting machine is equipped with a diagonal brace to ensure the horizontality of the vertical guide frame. The driving mechanism includes a rack assembly fixed to the vertical guide frame, and a gear and a drive motor fixed to the lifting platform. The gear meshes with the rack assembly, and when the drive motor drives the gear to rotate, it drives the lifting platform to rise and fall along the rack assembly. The rack assembly includes a T-rail, a side guard fixed to the T-rail, and a rack, which meshes with the gear. The lifting platform is also equipped with anti-detachment rollers and side rollers. The anti-detachment rollers roll in cooperation with the side guard of the rack assembly to prevent the gear from disengaging from the rack. The side rollers roll in cooperation with the T-rail of the rack assembly to prevent the lifting platform from shaking during the lifting process. The lifting platform is also equipped with a shuttle detection sensor to detect whether the shuttle is on the lifting platform. The lifting platform is also equipped with an overrun detection sensor to detect whether the shuttle or the goods it carries exceed the boundary of the lifting platform.

[0015] Furthermore, an embedded boost storage system and its operating method include the following steps:

[0016] The lifting platform is stopped at the initial cargo layer, and both the A locking actuator and the B locking actuator are in a limited position. That is, the limited end remains vertically upward under its own gravity and protrudes from the surface of the lifting platform to prevent the shuttle car from moving relative to the lifting platform in the X direction.

[0017] When the drive motor is energized, it rotates, driving the gear to rotate along the rack of the rack assembly, thereby causing the lifting platform to rise vertically in the Y direction along the vertical guide frame to the height of the target cargo placement channel. During the lifting process, the diagonal tie rod maintains the horizontality of the vertical guide frame, and the anti-detachment rollers on the lifting platform roll into contact with the side guards of the rack assembly to prevent the gear from disengaging from the rack. At the same time, the side rollers on the lifting platform roll into contact with the T-rail of the rack assembly to prevent the lifting platform from swaying during the lifting process.

[0018] When the lifting platform reaches the height of the target cargo placement channel, it docks with a pair of overhead guide rails at that height. The A locking actuator on the bracket beam switches from a limited position to a passable position under the contact of the B unlocking drive mechanism on the lifting platform. Simultaneously, the B locking actuator on the lifting platform switches from a limited position to a passable position under the contact of the A unlocking drive mechanism on the bracket beam. The magnets with opposite polarities on the A and B locking actuators attract each other, constraining the swaying amplitude caused by their collision inertia and assisting them in quickly stabilizing in the passable state.

[0019] The shuttle car travels along the X direction from the lifting platform to a pair of travel rails that are connected to the lifting platform, and then travels along the travel rails to the area below the target cargo location.

[0020] The lifting platform rises along the Y direction, lifting the cargo pallet and its contents off the shuttle car, detaching the cargo pallet from the shuttle car, and then horizontally placing the cargo pallet on the upper side of the two travel rails to complete the cargo storage; or the lifting platform rises along the Y direction, lifting the cargo pallet and its contents that are stationary on the upper side of the two travel rails and placing them on the shuttle car, and then the lifting platform descends along the Y direction, supporting the cargo pallet on the shuttle car to complete the cargo retrieval;

[0021] The shuttle, carrying the cargo pallet and cargo, travels along the guide rail back to the lifting platform. Once the shuttle has fully returned to the lifting platform, the A locking actuator disengages from the B unlocking drive mechanism, and the B locking actuator disengages from the A unlocking drive mechanism. The A locking actuator and the B locking actuator are then rapidly reset to their limit positions by their own weight and the attraction between magnets of opposite polarities on their limiting and counterweight ends. That is, the limiting end returns to a vertical position and protrudes from the surface of the lifting platform to prevent the shuttle from moving relative to the lifting platform in the X direction, thus locking the shuttle on the lifting platform.

[0022] Repeat the above steps until the goods are transferred between layers or the goods are moved in or out of the warehouse. During the execution of the above steps, the shuttle detection sensor on the lifting platform detects in real time whether the shuttle is on the lifting platform, and the overrun detection sensor on the lifting platform detects in real time whether the shuttle or the goods it carries exceed the boundary of the lifting platform. When the shuttle is detected to be off the lifting platform or the goods exceed the platform boundary, an alarm signal is issued and the lifting action of the lifting platform is stopped.

[0023] Beneficial Effects: This invention embeds the lifting mechanism into the automated storage and retrieval system (AS / RS), allowing for the placement of multiple lifting mechanisms within the system, thus reducing space requirements. Furthermore, its internal placement within the system enables shuttle vehicles to perform layer-changing operations with shorter travel distances, improving inbound and outbound efficiency. The use of existing rack columns further reduces overall cost. By incorporating a locking actuator and an unlocking drive mechanism, the shuttle vehicle and its cargo are stably positioned on the lifting platform during lifting, achieving locking during lifting, automatic unlocking upon reaching the target position, and returning to the locked position after the operation has ended. Magnets of opposite polarities are placed at the limiting end and counterweight end of the locking actuator, effectively restraining excessive swaying caused by collision inertia, preventing over-swinging of the locking actuator and limit failure, and assisting in the locking actuator to quickly reset to the limiting state after the lifting platform leaves the target layer. Through a purely mechanical locking system, the shuttle vehicle can be locked and positioned on the lifting platform without an additional power source during lifting, preventing the shuttle vehicle and cargo from sliding and falling due to power outages.

Detailed Implementation

[0034] The invention will now be further described with reference to the accompanying drawings.

[0035] like Figures 1 to 10 As shown, the embedded lifting storage system provided by the present invention includes a shelf 2, an embedded lifting machine 1, and a shuttle 1-4. The embedded lifting machine 1 is located on one side of the shelf 2 and includes a vertical guide frame 1-2, a lifting platform 1-5, and a drive mechanism for driving the lifting platform 1-5 to move up and down along the vertical guide frame 1-2. The shuttle 1-4 is located on the lifting platform 1-5 and can move up and down together with the lifting platform 1-5.

[0036] like Figure 1 As shown, the shelving unit 2 includes several horizontally extending cargo placement aisles, each with a pair of overhead crane rails 3 at its lower part. The vertical guide frame 1-2 extends in the Y direction, and the two overhead crane rails 3 extend in the X direction. When the lifting platform 1-5 is raised to the height of any cargo placement aisle, the lifting platform 1-5 docks with a pair of overhead crane rails 3 at the same height, and the shuttle 1-4 can travel from the lifting platform 1-5 to the pair of overhead crane rails 3 docked with the lifting platform 1-5.

[0037] like Figure 3 As shown, the shuttle 1-4 is equipped with a lifting platform 4, on which a cargo pallet 5 is supported, and on the cargo pallet 5, cargo 6 is supported. When the shuttle 1-4 travels on a pair of guide rails 3, the shuttle 1-4 is positioned between the two guide rails 3. The width of the cargo pallet 5 is wider than the width between the two guide rails 3. When the cargo pallet 5 and the cargo 6 on it are stored statically at any position in the cargo placement channel, the cargo pallet 5 is horizontally mounted on the upper side of the two guide rails 3.

[0038] The embedded lifting machine 1 is equipped with a locking system. When locked, the locking system locks the X-direction movement of the shuttle 1-4 on the lifting platform 1-5. When the lifting platform 1-5 is raised to the height of any cargo placement channel and docks with a pair of traveling rails 3 at the same height, the locking system automatically unlocks.

[0039] like Figure 6 and Figure 7 As shown, the locking system on the lifting platform 1-5 includes a B locking actuator 1-8B and a B unlocking drive mechanism 1-9B, both of which are installed on the lifting platform 1-5. The embedded lifting machine 1 is equipped with a pair of bracket beams 1-10 for each of the horizontally extending cargo placement channels on several layers of the shelf. The locking system on the bracket beams 1-10 includes an A locking actuator 1-8A and an A unlocking drive mechanism 1-9A, both of which are installed on the bracket beams 1-10.

[0040] The B unlocking drive mechanism 1-9B and the A locking actuator 1-8A are corresponding in the Y direction, and the A unlocking drive mechanism 1-9A and the B locking actuator 1-8B are corresponding in the Y direction. When the lifting platform 1-5 rises and falls to the target floor along the Y direction, the B unlocking drive mechanism 1-9B touches the A locking actuator 1-8A, and at the same time, the A unlocking drive mechanism 1-9A touches the B locking actuator 1-8B, causing the A locking actuator 1-8A and the B locking actuator 1-8B to synchronously switch from the limit state to the passage state.

[0041] like Figure 7As shown, both the A locking actuator 1-8A and the B locking actuator 1-8B include a limiting end 1-8-1, a counterweight end 1-8-2, and a collision block 1-8-3. Both the A locking actuator 1-8A and the B locking actuator 1-8B are mounted on the mounting base 1-8-5 of the bracket beam 1-10 and the lifting platform 1-5 respectively via a rotating shaft 1-8-4, and rotate around the rotating shaft 1-8-4 under the contact action of the corresponding unlocking drive mechanism. Magnets are provided on both the side of the mounting base 1-8-5 near the counterweight end 1-8-2 and the side of the counterweight end 1-8-2 near the mounting base 1-8-5. Magnets are also provided on the limiting end 1-8-1 and the counterweight end 1-8-2.

[0042] When in the limited position, the A locking actuator 1-8A and the B locking actuator 1-8B maintain the limiting end 1-8-1 in a vertically upward state due to their own weight and the magnetic attraction between the oppositely polarized magnets located on the side of the mounting base 1-8-5 near the counterweight end 1-8-2 and the side of the counterweight end 1-8-2 near the mounting base 1-8-5. At this time, the limiting end 1-8-1 protrudes from the surface of the lifting platform 1-5, preventing the shuttle 1-4 from moving in the X direction. When the unlocking drive mechanism touches the collision block 1-8-3, the locking actuator rotates around the rotation axis 1-8-4, and the limiting end 1-8-1 rotates from vertically upward to horizontal, releasing the obstruction of the shuttle 1-4.

[0043] The magnets on locking actuator 1-8A (A) and locking actuator 1-8B (B) have opposite polarities and generate an attractive force when they approach each other. This attractive force can restrain the swing amplitude of locking actuator 1-8A and locking actuator 1-8B caused by collision inertia and assist them in resetting.

[0044] Both the A unlocking drive mechanism 1-9A and the B unlocking drive mechanism 1-9B include an upper arc surface 1-9-1 and a lower arc surface 1-9-2. The collision block 1-8-3 includes an upper arc surface 1-8-31 and a lower arc surface 1-8-32.

[0045] like Figure 9 As shown, when the lifting platform 1-5 descends from top to bottom along the Y direction to the target layer, the lower arc surface 1-9-2 of the collision wheel assembly contacts the upper arc surface 1-8-31 of the collision block 1-8-3. The lower arc surface 1-9-2 and the upper arc surface 1-8-31 remain tangent during the contact process to guide the corresponding locking actuator to switch from the limit state to the passage state.

[0046] like Figure 10As shown, when the lifting platform 1-5 rises from bottom to top along the Y direction to the target layer, the upper arc surface 1-9-1 of the collision wheel assembly touches the lower arc surface 1-8-32 of the collision block 1-8-3. The upper arc surface 1-9-1 and the lower arc surface 1-8-32 remain tangent during the contact process to guide the corresponding locking actuator to switch from the limit state to the pass state.

[0047] Through the tangential engagement of the aforementioned arc surfaces, the collision wheel assembly can smoothly drive the locking actuator to rotate with minimal impact force, avoiding potential damage or jamming caused by rigid collisions.

[0048] like Figure 8 As shown, when the lifting platform 1-5 descends to the target layer, the counterweight ends 1-8-2 of the A locking actuator 1-8A and the B locking actuator 1-8B approach each other, and the magnets with opposite polarities on the counterweight ends 1-8-2 generate an attraction between them, so as to constrain the swing amplitude of the A locking actuator 1-8A and the B locking actuator 1-8B due to the collision inertia and assist them to quickly stabilize in the passage state.

[0049] Similarly, when the lifting platform 1-5 rises to the target layer, the limiting ends 1-8-1 of the A locking actuator 1-8A and the B locking actuator 1-8B approach each other. Since there is a spatial gap between the mechanical limiting components (1-8A) and (1-8B), the two limiting ends (1-8-1) are staggered in space. The magnets with opposite polarities on the limiting ends 1-8-1 generate an attraction force to constrain the swing amplitude of the A locking actuator 1-8A and the B locking actuator 1-8B due to collision inertia and assist them in quickly stabilizing in the passage state.

[0050] When the lifting platform 1-5 rises to the target floor, the limiting ends 1-8-1 of the A locking actuator 1-8A and the B locking actuator 1-8B approach each other. Since the A locking actuator 1-8A and the B locking actuator 1-8B are spatially spaced, the two limiting ends 1-8-1 are spatially staggered. The magnets with opposite polarities on the limiting ends 1-8-1 generate an attractive force, thus constraining the swing amplitude of the A locking actuator 1-8A and the B locking actuator 1-8B due to collision inertia and assisting them in quickly stabilizing in a passing state.

[0051] When the lifting platform 1-5 leaves the target layer, the A locking actuator 1-8A and the B locking actuator 1-8B move away from each other and are quickly reset to the limit state by their own gravity and the attraction force.

[0052] like Figure 2As shown, the vertical guide frame 1-2 is constructed using the uprights of the shelf 2, and the bottom of the embedded lifting machine 1 is provided with a diagonal tie rod 1-7 to ensure the levelness of the vertical guide frame.

[0053] like Figure 4 As shown, the driving mechanism includes a rack assembly 1-1 fixed to the vertical guide frame 1-2, and a gear 1-5-3 and a drive motor 1-5-2 fixed to the lifting platform 1-5. The gear 1-5-3 meshes with the rack assembly 1-1. When the drive motor 1-5-2 drives the gear 1-5-3 to rotate, it causes the lifting platform 1-5 to move up and down along the rack assembly 1-1.

[0054] The rack assembly 1-1 includes a T-rail 1-1-3, a lateral flange 1-1-1 fixed to the T-rail 1-1-3, and a rack 1-1-2, wherein the rack 1-1-2 meshes with a gear 1-5-3.

[0055] like Figure 6 As shown, the lifting platform 1-5 is also equipped with anti-detachment rollers 1-5-6 and side rollers 1-5-5. The anti-detachment rollers 1-5-6 are in rolling engagement with the side guard 1-1-1 of the rack assembly 1-1 to prevent the gear 1-5-3 from disengaging from the rack 1-1-2. The side rollers 1-5-5 are in rolling engagement with the T-rail 1-1-3 of the rack assembly 1-1 to prevent the lifting platform 1-5 from shaking during lifting.

[0056] The lifting platform 1-5 is also equipped with a shuttle detection sensor 1-5-1, used to detect whether the shuttle 1-4 is on the lifting platform 1-5. The lifting platform 1-5 is also equipped with an overrun detection sensor 1-5-4, used to detect whether the shuttle 1-4 or the goods it carries exceed the boundary of the lifting platform 1-5.

[0057] The lifting platform 4 can move up and down along the Y direction on the shuttle 1-4 to lift the cargo pallet 5 from the shuttle 1-4 or lower the cargo pallet 5 onto the shuttle 1-4.

[0058] The working method of the present invention will be described in detail below with reference to the above structure.

[0059] Driven by the drive mechanism, the lifting platform 1-5 rises and falls along the vertical guide frame 1-2. The B locking actuator 1-8B on the platform maintains a limit position, locking the shuttle 1-4 onto the lifting platform 1-5. When the lifting platform 1-5 rises to the height of the target cargo placement channel, it connects with the traveling guide rail 3. The B unlocking drive mechanism 1-9B touches the A locking actuator 1-8A, and the A unlocking drive mechanism 1-9A touches the B locking actuator 1-8B, causing both to simultaneously switch from limit position to passage. The magnetic attraction constrains the collision inertia and assists in rapid stabilization. The shuttle 1-4 moves to the target cargo position and is lifted... Platform 4 lifts the cargo pallet 5 and places it on the upper side of the traveling rail 3 to complete the storage, or the lifted cargo pallet 5 is carried on the shuttle car 1-4 to complete the retrieval; after the shuttle car 1-4 returns to the lifting platform 1-5 with the cargo, the unlocking drive mechanism and the locking execution mechanism disengage, and the two are reset to the limit position by gravity and magnetic force, locking the shuttle car 1-4 on the lifting platform 1-5; the above process is repeated until the operation is completed; during the process, the shuttle car detection sensor 1-5-1 and the overrun detection sensor 1-5-4 detect the position of the shuttle car and whether the cargo exceeds the boundary of the lifting platform 1-5 in real time, and alarm and stop the machine when abnormal.

[0060] Specifically, the lifting platform 1-5 is stopped at the initial cargo floor. Both locking actuators A-8A and B-8B are in a limited position, that is, the limiting end 1-8-1 is kept vertically upward under the action of its own gravity, i.e., the magnetic attraction force of the magnets with opposite polarities provided on the side of the mounting base 1-8-5 near the counterweight end 1-8-2 and the side of the counterweight end 1-8-2 near the mounting base 1-8-5, and protrudes from the surface of the lifting platform 1-5, locking the shuttle car 1-4 on the lifting platform 1-5 and preventing the shuttle car 1-4 from moving in the X direction.

[0061] When the drive motor 1-5-2 is energized, the drive gear 1-5-3 meshes with and rotates along the rack 1-1-2 of the rack assembly 1-1, causing the lifting platform 1-5 to vertically rise and fall along the vertical guide frame 1-2 in the Y direction to the height of the target cargo placement channel. During the lifting process, the diagonal tie rod 1-7 maintains the horizontality of the vertical guide frame; the anti-detachment roller 1-5-6 rolls with the side guard 1-1-1 to prevent the gear 1-5-3 from disengaging from the rack 1-1-2; the side roller 1-5-5 rolls with the T-rail 1-1-3 to prevent the lifting platform 1-5 from shaking.

[0062] When the lifting platform 1-5 reaches the height of the target cargo placement channel, it docks with a pair of overhead guide rails 3 at that height. The B unlocking drive mechanism 1-9B contacts the A locking actuator 1-8A, and simultaneously, the A unlocking drive mechanism 1-9A contacts the B locking actuator 1-8B, causing the A locking actuator 1-8A and the B locking actuator 1-8B to synchronously switch from the limit state to the passage state. During the switching process, magnets with opposite polarities on the A locking actuator 1-8A and the B locking actuator 1-8B generate an attraction force when they approach each other, thus restraining the swaying amplitude caused by collision inertia and assisting in quickly stabilizing them in the passage state.

[0063] The shuttle 1-4 travels along the X direction from the lifting platform 1-5 to the pair of travel rails 3 that connect with the lifting platform 1-5, and then travels along the travel rails 3 to below the target cargo location. The lifting platform 4 rises along the Y direction, lifting the cargo pallet 5 and the cargo 6 on it from the shuttle 1-4, detaching the cargo pallet 5 from the shuttle 1-4, and horizontally placing the cargo pallet 5 on the upper side of the two travel rails 3, completing the cargo storage. Alternatively, the lifting platform 4 rises along the Y direction, lifting the cargo pallet 5 and the cargo 6 that are stationary on the upper side of the two travel rails 3 and placing them on the shuttle 1-4, then the lifting platform 4 descends along the Y direction, supporting the cargo pallet 5 on the shuttle 1-4, completing the cargo retrieval.

[0064] The shuttle 1-4, carrying pallet 5 and cargo 6, travels along the guide rail 3 back to the lifting platform 1-5. Once the shuttle 1-4 has fully returned to the lifting platform 1-5, the B unlocking drive mechanism 1-9B disengages from the A locking actuator 1-8A, and the A unlocking drive mechanism 1-9A disengages from the B locking actuator 1-8B. The A locking actuator 1-8A and B locking actuator 1-8B quickly reset to their limit positions due to their own gravity and magnetic attraction, meaning the limit end 1-8-1 returns to a vertical position and protrudes from the surface of the lifting platform 1-5, locking the shuttle 1-4 onto the lifting platform 1-5.

[0065] Repeat the above process until the goods are transferred between layers or the goods are moved in or out of the warehouse.

[0066] During the execution of the above process, the shuttle detection sensor 1-5-1 continuously monitors whether the shuttle 1-4 is on the lifting platform 1-5, and the overrun detection sensor 1-5-4 continuously monitors whether the shuttle 1-4 or the goods it carries exceed the boundary of the lifting platform 1-5. When an abnormality is detected, the system issues an alarm signal and stops the lifting action of the lifting platform 1-5.

[0067] In a preferred embodiment, the attraction between the magnets on locking actuators A-8A and B-8B plays a crucial role when goods need to be quickly layered or moved in and out of the warehouse. During rapid operations, the collision speed between the locking actuator and the unlocking drive mechanism is faster, resulting in greater inertia on the locking actuator and excessive swaying. This swaying amplitude may exceed 180 degrees, preventing it from returning to its limit position and achieving the locking and limiting effect. The magnets on locking actuators A-8A and B-8B can constrain the excessive swaying amplitude caused by the collision inertia after a collision, limiting it to no more than 180 degrees. The magnetic force of the magnets should be selected based on the mass and rotational inertia of the locking actuator to ensure that it effectively constrains the swaying amplitude caused by the collision inertia without affecting the normal rotation and unlocking of the locking actuator under the impact of a collision due to excessive magnetic force.

[0068] The above are the preferred embodiments described in this invention.
