Description

Technical Field

[0001] This application relates to the field of warehousing and logistics, and more specifically to a fall protection device and a warehousing system. Background Technology

[0002] In modern automated storage and retrieval systems (AS / RS), four-way trolleys serve as core handling equipment and are widely used in high-density storage scenarios. Four-way trolleys can move flexibly horizontally on flat racks and perform vertical layer-changing operations via elevators, thus completing the storage, retrieval, and transfer of goods in three-dimensional space.

[0003] Existing four-way vehicle transfer systems typically consist of four-way vehicles, racks, elevators, and an electrical control system. The four-way vehicles connect to the elevator conveyor line via a steel platform on the ground floor, enabling cross-floor transport of goods. The physical structure of the transition area is completely open, relying solely on the electrical control system to coordinate the speed and position of the four-way vehicles and the lifting and lowering movements of the elevators. For example, the four-way vehicle needs to precisely decelerate and stop at the elevator entrance, placing the goods on the elevator conveyor line, after which the elevator delivers the goods to the target floor. If the four-way vehicle needs to transport goods across floors, it must drive into the elevator transfer area carrying the goods, where the elevator completes the transfer and returns.

[0004] However, existing technology does not include a mechanical anti-fall mechanism in the transition area between the four-way vehicle and the hoist. The physical permeability of the transition area can lead to problems such as falling from the transition area caused by electrical control system failures, operational errors, and dynamic load impacts. Summary of the Invention

[0005] This application provides a fall protection device and a warehousing system to solve the fall protection problem in the transition area between four-way vehicles and elevators in existing warehousing and logistics technologies.

[0006] In a first aspect, this application provides a fall arrest device for a conveying channel between a first conveying device and a second conveying device. The first conveying device is configured to convey goods via a first moving device, and the second conveying device is configured to convey goods via a second moving device. The fall arrest device includes: a locking seat, a deflector, and a triggering mechanism. The locking seat is disposed on the side of the conveying channel; the deflector is rotatably connected to the locking seat so that the deflector can be blocked in the conveying channel or allow goods to pass through the conveying channel; the triggering mechanism includes a trigger member that is movable relative to the locking seat; and the trigger member is configured to drive the deflector to rotate when it moves. The triggering mechanism can dock with the first moving device so that the first moving device drives the trigger member to move and causes the deflector to open the conveying channel.

[0007] This design solves the problem of preventing the second mobile device from falling in the transition area.

[0008] As an optional implementation, the triggering mechanism includes a torsion spring, a mounting bracket, and a guide assembly. The two ends of the torsion spring are respectively connected to a deflector and a locking seat. The mounting bracket is fixedly disposed on the side of the conveying channel, and the guide assembly is disposed on the mounting bracket. The guide assembly is configured to guide the trigger to move along a first direction, which is consistent with the moving direction of the first moving device.

[0009] With this configuration, the guide component restricts and guides the trigger to move linearly only along a first direction, which is parallel to the direction of operation of the first moving device within the conveying channel.

[0010] As an optional implementation, the fall arrestor also includes a transmission mechanism connected between the oscillating element and the trigger element.

[0011] This configuration allows for the establishment of a mechanical linkage between the oscillating component and the trigger component.

[0012] As an optional implementation, the trigger is a movable rack, and the triggering mechanism also includes a movable gear and a fixed rack. The first moving device has a connecting rod, the movable gear has a trigger groove located at its center, the fixed rack is fixedly mounted on the mounting bracket and extends along a first direction, the movable gear is slidably mounted on the mounting bracket and meshes with the fixed rack, its sliding direction is the first direction, and it is elastically suspended and supported on the mounting bracket by a first spring, the first spring being connected between the mounting bracket and the movable gear; the movable rack meshes with the other side of the movable gear, the connecting rod can engage with the trigger groove, and when the first moving device moves along the first direction, it drives the movable gear to roll relative to the fixed rack through the connecting rod, causing the movable rack to slide along the first direction.

[0013] This configuration amplifies the formation of the movable rack, ensuring that the first moving device can reliably trigger the anti-fall device to unlock even when operating at low speed.

[0014] As an optional implementation, the guide assembly includes a slide rail slider, which is fixedly mounted on a mounting bracket; both the fixed rack and the movable rack are parallel to the extension direction of the slide rail.

[0015] This configuration ensures that the direction of the driving force on the rack is completely aligned with its sliding direction, allowing the entire transmission chain to execute actions smoothly and without jamming, thus ensuring that the fall arrestor can respond with zero delay at critical moments.

[0016] As an optional implementation, the movable gear has a centrally located position in the first direction. When the connecting rod engages with the trigger slot and drives the movable gear away from the centrally located position, the first spring undergoes elastic deformation. When the connecting rod disengages from the trigger slot, the first spring releases its elastic force to drive the movable gear back to the centrally located position.

[0017] This configuration allows the sway block to be unlocked in both the descending and ascending states when the first moving device approaches the second conveying device.

[0018] As an optional implementation, the transmission mechanism includes a flexible element and multiple guide wheels, which are distributed on opposite sides of the transmission path of the flexible element, and each side is provided with at least one guide wheel.

[0019] This design limits the swaying of the flexible component perpendicular to the transmission direction and also ensures the tension of the flexible component.

[0020] As an optional implementation, the deflector is provided with a movable groove, and the anti-fall device also includes a tension shaft and a second spring;

[0021] The tension shaft is slidably disposed in the movable groove and is configured to move in a direction perpendicular to its own axis.

[0022] The second spring extends along the moving direction of the tension shaft, with one end connected to the inner wall of the movable groove and the other end directly connected to the side or end of the tension shaft; the flexible component is connected to the tension shaft.

[0023] When the triggering element drives the oscillating element to rotate through the flexible element, it drives the tensioning shaft to move laterally along the movable groove and compresses the second spring.

[0024] This setting can compensate for the positional offset of the trigger stroke and also avoid the overstretching of the flexible component.

[0025] As an optional implementation, the fall arrestor also includes a fixing bolt, which is detachably connected to one end of the tension shaft;

[0026] The fixing bolt has an axial through hole inside, which is used to accommodate the flexible component;

[0027] The sidewall of the fixing bolt has a slot that extends radially and connects to a through hole, allowing the flexible component to be laterally inserted into the through hole.

[0028] This setting allows for adjustment of the preload state of the flexible component.

[0029] As an optional implementation, the fall arrestor also includes a skew correction assembly, which comprises a lifting cylinder, a correction guide groove, a correction platform, and a derailment trigger rod. The lifting cylinder is fixedly mounted above the second conveying device; the correction guide groove is fixedly connected above the lifting cylinder; the correction platform is floatingly connected above the correction guide groove via a third spring; the bottom of the correction platform has a cylindrical structure; and the derailment trigger rod is fixedly connected to both sides of the correction platform.

[0030] When the second moving device deviates from the second conveying equipment to the first moving device, the derailment trigger rod is pressed and floats, driving the correction platform to move. Through photoelectric detection, the system controls the second moving device to stop running. At the same time, the lifting cylinder lifts upward. Under the gravity of the second moving device, the cylindrical structure is pressed into the guide groove of the correction guide groove to realize the deviance correction of the second moving device.

[0031] This design solves the technical problem of lateral displacement or even derailment of the moving device caused by track docking errors, wheel wear, or uneven load during the transition between equipment in the existing conveying system.

[0032] Secondly, this application provides a warehousing system, which includes a first conveying device, a plurality of second conveying devices, a first moving device, a plurality of second moving devices, and a fall protection device according to any of the above optional embodiments; the plurality of second conveying devices are arranged vertically; a plurality of fall protection devices are provided and are arranged in pairs between the first conveying device and the second conveying device; the first moving device can selectively stop at the second conveying device at different heights and dock with the second moving device; the second moving device moves horizontally on the second conveying device.

[0033] This design solves the problem of falls caused by electrical control system malfunctions, operational errors, and dynamic load impacts due to the lack of a mechanical fall arrest mechanism in the transition area between the second and first mobile devices, which is caused by the physical permeability of the transition area.

[0034] This application provides a fall arrest device and a warehousing system. The core technical concept is to construct a physical fall arrest protection layer in the transition area between the four-way vehicle and the hoist through the coordinated design of a mechanical linkage mechanism and a one-way locking structure. This achieves dynamic locking of the four-way vehicle and goods, thus providing redundant safety protection in case of electronic control system failure or operational errors. The core of this concept lies in using the physical characteristics of the mechanical structure itself to replace purely electronic control logic, transforming the fall arrest function, which originally relied on software control, into hardware-level safety assurance. By linking the fall arrest mechanism with the lifting action of the hoist, the fall arrest device can be automatically triggered and reset. At the same time, the double stroke design improves the trigger sensitivity and adapts to the slow operation of the hoist, thereby covering the safety needs of all scenarios.

[0050] It should be noted that if the embodiments of this application involve descriptions such as "first" and "second," such descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" and "second" may explicitly or implicitly include at least one of those features.

[0051] In modern automated storage and retrieval systems (AS / RS), four-way trolleys serve as core handling equipment and are widely used in high-density storage scenarios. Four-way trolleys can move flexibly horizontally on flat racks and perform vertical layer-changing operations via elevators, thus completing the storage, retrieval, and transfer of goods in three-dimensional space.

[0052] Existing four-way vehicle transfer systems typically consist of four-way vehicles, racks, elevators, and an electrical control system. The four-way vehicles connect to the elevator conveyor line via a steel platform on the ground floor, enabling cross-floor transport of goods. The physical structure of the transition area is completely open, relying solely on the electrical control system to coordinate the speed and position of the four-way vehicles and the lifting and lowering movements of the elevators. For example, the four-way vehicle needs to precisely decelerate and stop at the elevator entrance, placing the goods on the elevator conveyor line, after which the elevator delivers the goods to the target floor. If the four-way vehicle needs to transport goods across floors, it must drive into the elevator transfer area carrying the goods, where the elevator completes the transfer and returns.

[0053] However, existing technology does not include a mechanical anti-fall mechanism in the transition area between the four-way vehicle and the hoist. The physical permeability of the transition area can lead to problems such as falling from the transition area caused by electrical control system failures, operational errors, and dynamic load impacts.

[0054] This application provides a fall protection device and a warehousing system to solve the fall protection problem in the transition area between four-way vehicles and elevators in existing warehousing and logistics technologies.

[0056] Figure 2 This is a schematic diagram of the overall structure of a fall protection device according to an embodiment of this application;

[0057] Figure 3 This is a schematic diagram of the internal structure of a fall protection device according to an embodiment of this application;

[0058] Figure 4 This is a schematic diagram of the structure of a triggering device according to an embodiment of this application.

[0059] See Figures 1 to 4 In one aspect, this application provides a fall arrestor 2 for a conveying channel between a first conveying device 1 and a second conveying device 4. The first conveying device 1 is configured to convey goods via a first moving device 5, and the second conveying device 4 is configured to convey goods via a second moving device 3. The fall arrestor 2 includes: a locking seat 10, a deflector 6, and a triggering mechanism 8. The locking seat 10 is disposed on the side of the conveying channel; the deflector 6 is rotatably connected to the locking seat 10 so that the deflector 6 can be blocked in the conveying channel or allow goods to pass through the conveying channel; the triggering mechanism 8 includes a trigger member that is movable relative to the locking seat 10; and the trigger member is configured to drive the deflector 6 to rotate when it moves. The triggering mechanism 8 can dock with the first moving device 5 so that the first moving device 5 drives the trigger member to move and drives the deflector 6 to open the conveying channel.

[0060] Understandably, this setup solves the fall prevention problem for the second mobile device 3 in the transition area.

[0061] It should be noted that the significant technical benefits of this solution are mainly reflected in two dimensions: security and synchronization.

[0062] Intrinsic safety and prevention of misoperation: Since the opening of the passageway strictly depends on the actual physical movement of the first moving device 5, the problem of accidental opening of the passageway due to electrical faults, sensor malfunctions, or human error is fundamentally eliminated. The passageway will only open when there is a genuine need to transport goods and the moving device is in position, greatly improving the fall-prevention reliability of the conveyor passageway during non-operational periods.

[0063] High degree of synchronization of actions: The action of triggering the door opening is completely synchronized with the action of transporting goods in time and space, ensuring the smoothness and continuity of goods passage.

[0064] As an optional implementation, the triggering mechanism 8 includes a torsion spring 9, a mounting bracket, and a guide assembly. The two ends of the torsion spring 9 are respectively connected to the deflector 6 and the locking seat 10. The mounting bracket is fixedly disposed on the side of the conveying channel, and the guide assembly is disposed on the mounting bracket. The guide assembly is configured to guide the trigger to move along a first direction, which is consistent with the moving direction of the first moving device 5.

[0065] Understandably, the guide component restricts and guides the trigger to move linearly only along a first direction, which is parallel to the direction of operation of the first moving device 5 within the conveying channel.

[0066] It should be noted that this "directional consistency" design is key to ensuring the sensitive response of the fall arrestor 2. Because the movement trajectory of the trigger element is perfectly aligned with the movement trajectory of the first moving device 5, when the first moving device 5 experiences overspeed, loss of control, or positional deviation, the resulting mechanical forces (such as collision, friction, or linkage drive) can be directly transmitted to the trigger element with minimal energy loss, avoiding lateral force components or jamming caused by angular deviations. Simultaneously, the guide assembly eliminates the swaying of the trigger element in other degrees of freedom, ensuring the accuracy of the trigger signal input. This allows the fall arrestor 2 to accurately identify abnormal states and initiate the locking procedure, thereby greatly improving the safety of the storage system.

[0067] As an optional implementation, the fall arrestor 2 also includes a transmission mechanism connected between the oscillating member 6 and the trigger member.

[0068] Understandably, this setup establishes a mechanical linkage between the oscillating component 6 and the trigger component.

[0069] It should be noted that the introduction of the transmission mechanism enables the optimized transformation of the motion form or force transmission path. This design not only solves the potential spatial mismatch between the oscillating component 6 and the trigger component, allowing them to be arranged in more flexible positions, but also adjusts the trigger sensitivity by setting the transmission ratio. This ensures that sufficient driving force can be generated to overcome the motion resistance of the trigger component even when a minor anomaly is detected, guaranteeing the reliability and timeliness of the fall arrestor 2's operation.

[0070] As an optional implementation, the trigger is a movable rack 15. The triggering mechanism 8 also includes a movable gear 17 and a fixed rack 19. The first moving device 5 has a connecting rod 21. The movable gear 17 has a trigger groove 18 located at its center. The fixed rack 19 is fixedly mounted on the mounting bracket and extends along the first direction. The movable gear 17 is slidably mounted on the mounting bracket and meshes with the fixed rack 19. Its sliding direction is the first direction, and it is elastically suspended and supported on the mounting bracket by a first spring 12. The first spring 12 is connected between the mounting bracket and the movable gear 17. The movable rack 15 meshes with the other side of the movable gear 17. The connecting rod 21 can be engaged with the trigger groove 18. When the first moving device 5 moves along the first direction, it drives the movable gear 17 to roll relative to the fixed rack 19 through the connecting rod 21, thereby driving the movable rack 15 to slide along the first direction.

[0071] Understandably, when the plug rod 21 drives the movable gear 17 to roll, the rotation of the gear is directly converted into the linear displacement of the movable rack 15. This mechanical linkage method is responsive, compact in structure, and amplifies the displacement by utilizing the meshing characteristics of the gears, reliably activating the subsequent unlocking mechanism.

[0072] As an optional implementation, the guide assembly includes a slide rail slider 16, which is fixedly mounted on a mounting bracket; the fixed rack 19 and the movable rack 15 are both parallel to the extension direction of the slide rail.

[0073] It should be noted that by setting the extension directions of the fixed rack 19 and the movable rack 15 to be strictly parallel to the guiding direction of the slide rail, a highly collinear motion constraint system is constructed. This design ensures that when the movable gear 17 rolls along the fixed rack 19, the movement trajectory of its axis is precisely restricted to a single degree of freedom by the slide rail slider 16, completely eliminating lateral components or deflection torques perpendicular to the direction of motion. Since the movable rack 15 is also parallel to this direction, when the movable gear 17 drives the movable rack 15, the direction of the driving force on the rack is completely coincident with its sliding direction, avoiding the "stuck" phenomenon or local stress concentration caused by angular deviation. This not only significantly reduces mechanical friction resistance and wear rate, extending component life, but also ensures that the entire transmission chain can perform actions smoothly and without jamming under high-speed operation or emergency triggering conditions, ensuring that the fall arrestor 2 can respond with zero delay at critical moments.

[0074] As an optional implementation, the movable gear 17 has a central position in the first direction. When the insertion rod 21 engages with the trigger groove 18 and drives the movable gear 17 away from the central position, the first spring 12 undergoes elastic deformation. When the insertion rod 21 disengages from the trigger groove 18, the first spring 12 releases its elastic force to drive the movable gear 17 back to the central position.

[0075] It is understandable that when the plug rod 21 causes the first moving device 5 to approach the second conveying device 4, both the descending and ascending states can trigger the sway block to unlock.

[0076] As an optional implementation, the transmission mechanism includes a flexible member 13 and a plurality of guide wheels 7, which are distributed on opposite sides of the transmission path of the flexible member 13, and each side is provided with at least one guide wheel 7.

[0077] For example, refer to Figure 3 There are three guide wheels 7 in total. Two are located on opposite sides near the triggering device, and one is located near the deflector 6.

[0078] Understandably, the guide wheels 7 on opposite sides near the triggering device clamp the flexible member 13, restricting its swing in the direction perpendicular to the transmission direction, while the guide wheels 7 near the deflector 6 also ensure the tension of the flexible member 13.

[0079] As an optional implementation, the deflector 6 is provided with a movable groove 22, and the anti-fall device 2 also includes a tension shaft 14 and a second spring 20;

[0080] The tension shaft 14 is slidably disposed in the movable groove 22 and is configured to move in a direction perpendicular to its own axis;

[0081] The second spring 20 extends along the moving direction of the tension shaft 14, with one end connected to the inner wall of the movable groove 22 and the other end directly connected to the side or end of the tension shaft 14; the flexible member 13 is connected to the tension shaft 14.

[0082] When the triggering element drives the oscillating element 6 to rotate via the flexible element 13, it drives the tensioning shaft 14 to move laterally along the movable groove 22 and compresses the second spring 20.

[0083] It is understandable that by introducing the elastic floating assembly of the tension shaft 14 and the second spring 20, a dynamic buffer and adaptive adjustment mechanism is constructed in the rigid mechanical transmission chain, which can compensate for the positional offset of the trigger stroke and avoid the overstretching of the flexible part 13.

[0084] As an optional implementation, the fall arrestor 2 also includes a fixing bolt 11, which is detachably connected to one end of the tension shaft 14;

[0085] The fixing bolt 11 has an axial through hole inside, which is used to accommodate the flexible part 13;

[0086] The sidewall of the fixing bolt 11 is provided with a slot, which extends radially and connects to the through hole, so that the flexible member 13 can be inserted into the through hole from the side.

[0087] It should be noted that the fixing bolt 11 and the tension shaft 14 are engaged by threads, and rotating the bolt drives it to produce linear displacement along the axial direction. Since the flexible element 13 is confined within the bolt through hole, the axial feed of the bolt is directly converted into a forced tension on the flexible element 13. This design simplifies the complex tension adjustment to a single rotational action, achieving both fine-tuning of the preload state and ensuring long-term stability of the tension force by utilizing the self-locking characteristic of the thread.

[0088] See Figure 5 and Figure 6 As an optional implementation, the fall arrestor also includes a skew correction assembly, which includes a lifting cylinder 28, a correction guide 27, a correction platform 24, and a derailment trigger rod 26. The lifting cylinder 28 is fixedly mounted above the second conveying device 4; the correction guide 27 is fixedly connected above the lifting cylinder 28; the correction platform 24 is floatingly connected above the correction guide 27 via a third spring 25; the bottom of the correction platform 24 has a cylindrical structure 23; and the derailment trigger rod 26 is fixedly connected to both sides of the correction platform 24.

[0089] When the second moving device 3 deviates from the second conveying device 4 to the first moving device 5, the derailment trigger rod 26 is pressed and floats, driving the correction platform 24 to move. Through photoelectric detection, the system controls the second moving device 3 to stop running. At the same time, the lifting cylinder 28 lifts upward. Under the gravity of the second moving device 3, the cylindrical structure 23 is pressed into the guide groove of the correction guide groove 27 to achieve the deviance correction of the second moving device 3.

[0090] For example, the guide groove is V-shaped.

[0091] It should be noted that the design of this skew correction component has multiple technical advantages:

[0092] Highly sensitive triggering mechanism: A wide-range sensitive detection zone is constructed by utilizing a spring-loaded floating correction platform 24 and derailment trigger rods 26 extending on both sides. As long as the moving device slightly deviates and touches the derailment trigger rod 26, it can be quickly converted into an electrical signal through mechanical linkage, ensuring that the system intervenes in time before a catastrophic derailment occurs.

[0093] Gravity-assisted self-locking guidance: This cleverly utilizes the gravity of the second moving device 3 itself. When the lifting cylinder 28 lifts the correction platform 24, it does not simply rely on hydraulic / pneumatic pressure to forcibly push the moving device back, but instead allows the gravity of the moving device to act on the cylindrical structure 23 pressed into the guide groove. This design allows the correction force to naturally increase with the load, ensuring the correction effect under heavy load while avoiding excessive force that could damage the chassis of the moving device.

[0094] Precise geometric constraints: The fit between the cylindrical structure 23 and the guide groove forms a clear kinematic pair constraint. Once the cylinder enters the guide groove, the lateral degree of freedom of the moving device is completely restricted, and it can only reset along the predetermined trajectory, ensuring high accuracy and reliability of the correction.

[0095] Safety interlock protection: The logic interlock between photoelectric detection and lifting action and stop command prevents severe impact or secondary accidents that may be caused by forcibly correcting the deviation while the moving device is still running at high speed, thus ensuring the safety of the entire conveying system.

[0096] Secondly, this application provides a storage system, which includes a first conveying device 1, a plurality of second conveying devices 4, a first moving device 5, a plurality of second moving devices 3, and a fall arrestor 2 according to any of the above optional embodiments; the plurality of second conveying devices 4 are arranged vertically; a plurality of fall arrestors 2 are provided and are arranged in pairs between the first conveying device 1 and the second conveying devices 4; the first moving device 5 can selectively stop at the second conveying devices 4 at different heights and dock with the second moving device 3; the second moving device 3 moves horizontally on the second conveying devices 4.

[0097] It should be noted that integrating the aforementioned fall arrestor 2 into this warehousing system addresses a core safety concern in multi-level automated storage environments: When the second mobile device 3 passes the first mobile device 5, it arrives at the first mobile device 5's entry point beforehand to place goods or transport goods to the first mobile device 5 for transfer. The transition between the second mobile device 3 and the first mobile device 5 is completely unobstructed. However, in the event of a power outage, goods and the second mobile device 3 could fall into the first mobile device 5, posing a safety hazard. The "paired" fall arrestor 2 in this solution provides redundant protection: even if one device fails due to obstruction by foreign objects, the other device can still independently perform a locking action, ensuring the second mobile device 3 is reliably and safely stopped. This purely mechanical locking structure significantly improves the inherent safety level and operational reliability of the entire automated storage system under extreme conditions such as power outages and fires.

[0098] For example, in an optional warehousing system, the first mobile device 5 is a hoist, the second mobile device 3 is a four-way vehicle, the first conveying device 1 is a hoist conveyor line, and the second conveying device 4 is a steel platform conveyor line.
