Description

Technical Field

[0001] This utility model belongs to the field of intelligent warehousing technology, and more specifically, it is a blocking device for the track of an automated warehouse rack. Background Technology

[0002] In smart warehousing, after a shuttle car completes the transfer of goods from a storage location on an automated racking system, it needs to travel along the track on the racking system to the end of the track and stop there to wait for the lifting platform on one side of the racking system to dock with the end of the track. In conventional technology, signals or sensors are usually used to control the shuttle car to stop at the end of the track. However, due to factors such as the inertia of the shuttle car and the goods, the lag in signal and sensor control, and the friction between the shuttle car rollers and the track, the shuttle car is prone to dropping goods from the end of the automated racking system. Summary of the Invention

[0003] Purpose of the invention: To overcome the shortcomings of the existing technology, this utility model provides a blocking device for the racking track of an automated warehouse. By improving the dynamic docking mechanism between the lifting platform and the racking track, it solves the safety hazard of shuttle cars accidentally leaving the track when not docked, while ensuring smooth passage of the shuttle cars when docked. Through the synergistic effect of the blocking component and the drive component, the blocking component restricts the movement of the shuttle cars under normal conditions, and automatically releases the obstruction when the lifting platform docks, thus balancing safety and operational efficiency.

[0004] Technical Solution: To achieve the above objectives, this utility model provides a blocking device for a racking track in an automated warehouse, comprising a lifting platform and a racking track. The lifting platform can be raised and lowered to engage with the racking track. A crossbeam is fixedly installed on the side of the racking track near the lifting platform, and the crossbeam is not higher than the travel surface of the racking track. A blocking component is installed on the side of the crossbeam near the lifting platform. Under normal conditions, the upper end of the blocking component is higher than the lower end of the shuttle car traveling on the racking track. A drive component is installed on the side of the lifting platform near the racking track corresponding to the blocking component. When the lifting platform rises to engage with the racking track, the drive component drives the upper end of the blocking component to deflect below the lower end of the shuttle car traveling on the racking track.

[0005] Furthermore, the blocking assembly includes a fixed base, a rotating body, and a collision block. The fixed base is fixedly installed on the side of the beam away from the shelf track. The rotating body is rotatably fitted onto the fixed base on the side away from the shelf via a bearing. The collision block is installed on the side of the rotating body away from the shelf track and is located below the bearing. When the collision block is impacted, the rotating body can rotate or swing relative to the fixed base around the bearing.

[0006] Furthermore, the drive assembly includes a drive block, which is fixedly installed on the side of the lifting platform near the shelf track via a mounting base and moves vertically relative to the shelf track in sync with the lifting platform. When the lifting platform rises to dock with the shelf track, the drive block can collide with the collision block.

[0007] Furthermore, the rotating body includes a slender, smaller end and a wide, shorter, larger end. The smaller end is integrally connected to the center of the top of the larger end. A bearing cover that mates with the bearing is provided at the center of the connection area between the larger and smaller ends. A waist-shaped weight-reducing groove is provided on the smaller end. The center of gravity of the rotating body is located on the side of the bearing closer to the larger end.

[0008] Furthermore, a counterweight is installed on the larger end of the rotating body, so that the rotating body always remains vertically upward under the action of gravity alone.

[0009] Furthermore, magnets are provided on the sides of the blocking component's fixed base and the rotating body that are close to each other. After the driving block of the rotating drive component separates from the collision block on the rotating body, the attraction between the two magnets can prevent the rotating body from swinging under the action of inertia.

[0010] Beneficial Effects: This utility model provides a blocking device for automated warehouse racking tracks. Through the automatic opening and closing function of the blocking components, it can prevent vehicles from falling in non-docked states using a blocking structure higher than the lower end of the shuttle car body. Furthermore, when the lifting platform is docking, the driving component triggers the blocking components to deflect to a safe position, achieving seamless passage. The design of the rotating main body counterweight and magnet enhances the stability of the device and reduces the impact of inertial swaying on blocking accuracy. The lightweight and modular structure not only extends the service life but also reduces maintenance costs, improving the safety and automation level of automated warehouse operations.

[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] like Figure 1 As shown, a blocking device for a racking track in an automated warehouse includes a lifting platform 2 and a racking track 5. The racking track 5 is installed on the automated racking 1, and the lifting platform 2 can be vertically raised and lowered relative to the automated racking 1 via a lifting device. The lifting platform 2 can be raised and lowered to engage with the racking track 5. A shuttle 6 is installed on the racking track 5. In the engaged state, the travel surface of the racking track 5 and the lifting surface of the lifting platform 2 are at the same horizontal plane. A crossbeam 8 is fixedly installed on the side of the racking track 5 near the lifting platform 2, and the crossbeam 8 is not higher than the travel surface of the racking track 5. A blocking component 3 is installed on the side of the crossbeam 8 near the lifting platform 2. Under normal conditions, the upper end of the blocking component 3 is higher than the lower end of the shuttle 6 traveling on the racking track 5. A drive component 4 is installed on the side of the lifting platform 2 near the racking track 5 corresponding to the blocking component 3. When the lifting platform 2 rises to engage with the racking track 5, the drive component 4 drives the upper end of the blocking component 3 to deflect below the lower end of the shuttle 6 traveling on the racking track 5.

[0018] When the shuttle 6 on the rack track 5 needs to be transferred via the lifting platform 2, before the lifting platform 2 is fully connected with the rack track 5, the blocking component 3 on the crossbeam 8 prevents the shuttle 6 from moving from the rack track 5 to the lifting platform 2 after receiving an incorrect command, so as to prevent the shuttle 6 from falling from the three-dimensional rack 1 to the ground due to receiving an incorrect command.

[0019] like Figure 2 and 3 As shown, the blocking assembly 3 includes a fixed base 9, a rotating body 10, and a collision block 11. The fixed base 9 is fixedly installed on the side of the crossbeam 8 away from the shelf track 5. The rotating body 10 is rotatably fitted on the side of the fixed base 9 away from the shelf 1 via a bearing 19. The collision block 11 is installed on the side of the rotating body 10 away from the shelf track 5, and the collision block 11 is located below the bearing 19. Under no external force, the rotating body 10 always remains vertically upward, and the top of the rotating body 10 is higher than the travel surface of the shelf track 5 and the lifting plane of the lifting platform 2. When the collision block 11 is impacted, the rotating body 10 can rotate or swing relative to the fixed base 9 around the bearing 19.

[0020] like Figure 4 As shown, the drive assembly 4 includes a drive block 16, which is fixedly installed on the side of the lifting platform 2 near the shelf track 5 via a mounting base 17, and moves vertically relative to the shelf track 5 in sync with the lifting platform 2. When the lifting platform 2 rises to dock with the shelf track 5, the drive block 16 can collide with the collision block 11.

[0021] like Figure 5 As shown, during the process of the lifting platform 2 docking with the shelf track 5 of the three-dimensional rack 1 through the lifting mechanism, the driving blocks 16 of the two driving components 4 come into contact with the collision blocks 11 of the blocking components 3, and drive the rotating body 10 to rotate around the bearing 19 until the upper end of the smaller end 13 of the rotating body 10 rotates to deflect to a position lower than the lower end of the shuttle 6 traveling on the shelf track 5; thereby avoiding the rotating body 10 from hindering the shuttle 6 from moving from the shelf track 5 to the lifting platform 2 after the lifting platform 2 docks with the shelf track 5, or the rotating body 10 from hindering the shuttle 6 from moving from the lifting platform 2 to the shelf track 5.

[0022] The rotating body 10 includes a slender, smaller end 13 and a wide, shorter, larger end 14. The smaller end 13 is integrally connected to the center of the top of the larger end 14. A bearing cover 7 that mates with the bearing 19 is provided at the center of the connection area between the larger end 14 and the smaller end 13. A waist-shaped weight-reducing groove 15 is provided on the smaller end 13. The center of gravity of the rotating body 10 is located on the side of the bearing 19 closer to the larger end 14. The side of the larger end 14 away from the smaller end 13 has an arc-shaped profile. This design can effectively reduce the impact of unit A 3 on the handling of goods on the lower level.

[0023] A counterweight 12 is installed on the larger end 14 of the rotating body 10. Under the action of gravity alone, the rotating body 10 always remains vertically upward.

[0024] Magnets 18 are provided on the side of the fixed base 9 of the blocking assembly and the rotating body 10 that are close to each other. After the driving block 16 of the rotating drive assembly separates from the collision block 11 on the rotating body 10, the attraction between the two magnets 18 can prevent the rotating body 10 from swinging under the action of inertia.

[0025] In the initial state, the blocking component 3 on the crossbeam 8 is in a vertical state, and the smaller end 13 of the rotating body 10 of the blocking component 3 protrudes from the travel surface of the shelf track 5, and the lifting platform 2 is located at the bottom of the lifting mechanism.

[0026] The working principle of a blocking device for automated warehouse racking tracks according to this utility model:

[0027] After the shuttle 6 completes the task of transporting goods from the shelf 1, the shuttle 6 travels along the shelf track 5 on the shelf 1 to the end of the shelf track 5. At this time, the smaller end 13 of the rotating body 10 of the blocking assembly 3 installed on the crossbeam 8 protrudes from the travel surface of the shelf track 5, and the smaller end 13 can make a limiting contact with the shuttle 6 on the shelf track 5, thereby preventing the shuttle 6 from falling from the end of the shelf track 5.

[0028] When the shuttle 6 needs to be transferred via the lifting platform, before the lifting platform 2 rises to complete docking with the rack track 5, the blocking component 3 on the crossbeam 8 prevents the shuttle 6 from moving from the rack track 5 to the lifting platform 2 after receiving an incorrect command, so as to avoid the shuttle 6 falling from the three-dimensional rack 1 to the ground due to receiving an incorrect command.

[0029] During the process of the lifting platform 2 docking with the rack track 5 of the three-dimensional rack 1 through the lifting mechanism, the driving block 16 of the driving component 4 contacts the collision block 11 of the blocking component 3 and drives the rotating body 10 to rotate around the bearing 19 until the upper end of the smaller end 13 of the rotating body 10 rotates to deflect to a position lower than the lower end of the shuttle 6 traveling on the rack track 5; thereby preventing the rotating body 10 from hindering the shuttle 6 from moving from the rack track 5 to the lifting platform 2 after the lifting platform 2 docks with the rack track 5, or preventing the shuttle 6 from moving from the lifting platform 2 to the rack track 5.

[0030] When the shuttle 6 carrying goods moves from the shelf track 5 to the lifting platform 2, the drive assembly 4 descends synchronously with the lifting platform 2. During this process, under the combined action of its own weight and the counterweight 12, the rotating body 10 will rotate around the bearing 19 in the opposite direction to the docking process, and the outline of the collision block 11 on the blocking assembly 3 will always match the drive block 16 of the drive assembly 4 until the blocking assembly 3 and the drive assembly 4 are released from contact.

[0031] After the blocking component 3 and the driving component 4 are released from contact, the A unit 3 quickly rotates around the bearing 19 to a vertical position under the action of the magnet 18.

[0032] The above are the preferred embodiments described in this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
