Description

Technical Field

[0001] This invention relates to the field of freight elevators, and more particularly to an intelligent, floor-level unmanned freight elevator. Background Technology

[0002] With the rapid development of smart warehousing and automated logistics, unmanned freight vehicles have been widely used in warehouses, workshops, and other scenarios. These vehicles can automatically travel along preset paths, transporting shelves from storage areas to freight elevators, and then using the elevators to achieve vertical transportation of goods between different floors, completing the entire process of automated cross-floor transfer. However, in practical applications, the car space of freight elevators is usually limited. In order to improve the efficiency of a single transport, multiple shelves often need to be stacked tightly together. This tight stacking method not only limits the number of shelves that can be placed in the elevator, making it difficult to meet the ever-increasing logistics throughput demand, but also leaves almost no gaps between the shelves, causing great inconvenience to subsequent loading, unloading, and scheduling operations. More seriously, during the elevator's lifting and transport process, the starting, acceleration, braking, and slight shaking of the car can cause repeated and violent collisions between the tightly stacked shelves and between them and the inner wall of the elevator car, seriously affecting the service life and load-bearing safety of these shelves. In addition, they also pose a risk of tilting and collapsing when the elevator car shakes, which may cause damage to goods and safety accidents. Therefore, how to effectively solve the problems of limited capacity and collision damage when unmanned freight vehicles transport shelves in the narrow space of elevators has become an urgent technical problem to be solved. Summary of the Invention

[0003] To overcome the limitations of unmanned freight vehicles in transporting shelves within the confined space of an elevator, and the risk of collision damage, this invention provides an intelligent, layered unmanned freight elevator.

Detailed Implementation

[0025] The present invention will now be described in detail with reference to the accompanying drawings.

[0026] Example 1: An intelligent, layered, unmanned freight elevator, as described in this example... Figures 1-7 As shown, the system includes an electrically controlled lifting slide rail 1, a platform 11, a main control panel 12, a freight elevator car 2, a longitudinal partition 21, a transverse partition 22, a lifting partition 3, a first winding machine 31, a steel wire rope 32, a second winding machine 6, and a roller shutter door 61. The platform 11 is fixedly connected to the bottom of the electrically controlled lifting slide rail 1, and the upper surface of the platform 11 is flush with the ground floor. The freight elevator car 2 is slidably connected inside the electrically controlled lifting slide rail 1. A main control panel 12 is installed on the electrically controlled lifting slide rail 1 to manually control the up and down movement of the freight elevator car 2. The freight elevator car 2 has a longitudinal partition 21 that divides the interior space of the freight elevator car 2 into two independent compartments 201, the bottom of which is initially flush with the upper surface of the platform 11. Each of the two independent compartments 201 is fixedly connected to a transverse partition 22 in the middle; each of the two independent compartments 201 of the freight elevator car 2 is slidably connected to a lifting partition 3, the lifting partition 3 having a through groove 301 in the middle that avoids the transverse partition 22, and the lifting partition 3 is initially attached to the inner bottom of the independent compartment 201; the freight elevator car 2 is equipped with two first winding machines 31 on the left and right; each of the two first winding machines 31 has two steel wire ropes 32 wound around its winding component; the steel wire ropes 32 on the two first winding machines 31 are fixedly connected to the lifting partition 3 on the same side; the freight elevator car 2 is equipped with two second winding machines 6 at the front and rear; each of the two second winding machines 6 winds a roller shutter door 61; the two roller shutter doors 61 are slidably connected to the front and rear sides of the freight elevator car 2 respectively.

[0027] like Figures 5-7As shown, each of the two lifting partitions 3 has two hollowed-out track grooves 302 on its front and rear sides. When the unmanned freight trolley transports the shelves onto the lifting partition 3, the caster parts of the unmanned freight trolley move along the bottom of the independent compartment 201 through the hollowed-out track grooves 302 of the lifting partition 3, so that the shelves carried on the unmanned freight trolley can be smoothly transported to the top of the lifting partition 3. However, the caster parts of the unmanned freight trolley do not need to move upwards onto the lifting partition 3, so as to avoid a height difference between the lifting partition 3 and the bottom of the independent compartment 201, which would cause the unmanned freight trolley to tilt and the shelves to tip over during the process of driving onto the lifting partition 3. A first positioning sticker 51 is fixedly attached to the front and rear sides of the upper surface of each of the two lifting partitions 3. A second positioning sticker 52 is fixedly attached to the front and rear sides of the bottom of each of the two independent compartments 201 of the freight elevator car 2.

[0028] An intelligent, layered, unmanned freight elevator mainly consists of an electrically controlled lifting rail 1 and a freight car 2. The freight car 2 has front and rear access passages. The interior of the freight car 2 is divided into two independent compartments 201 by a longitudinal partition 21. Each independent compartment 201 is further divided into two placement areas by a transverse partition 22. Each independent compartment 201 also has a liftable partition 3. When the first winding machine 31 pulls the steel wire rope 32, causing the partition 3 to rise to half its height within the independent compartment 201, as... Figure 9 As shown, the independent compartment 201 is divided into two independent placement areas by the lifting partition 3, resulting in a total of eight independent placement areas in the independent compartment 201, which greatly increases the storage capacity of the shelves, while keeping the shelves isolated from each other to prevent collision damage.

[0029] When the first batch of unmanned freight vehicles place the shelves on the lifting partition 3, the lifting partition 3 is initially in a state of close contact with the bottom of the independent compartment 201. At this time, the second winding machine 6 drives the roller shutter door 61 to rise and open the entrance and exit of the freight elevator car 2. The unmanned freight vehicle moves along the platform 11 to the independent compartment 201 of the freight elevator car 2. The unmanned freight vehicle moves along the hollow track groove 302 to transport the shelves onto the lifting partition 3. When the identification sensor at the bottom of the unmanned freight vehicle identifies the corresponding first positioning sticker 51 on the lifting partition 3, This indicates that the shelves on the unmanned freight vehicle have been aligned with the designated positions on the lifting partition 3. At this point, the unmanned freight vehicle only needs to unload the shelves and place them on the lifting partition 3 to complete the loading work. After that, the unmanned freight vehicle leaves the freight elevator car 2 and the platform 11. After the shelves are loaded on both the front and rear sides of the two lifting partitions 3, the first winding machine 31 pulls the steel wire rope 32 to lift the lifting partition 3 up to half the height of the independent compartment 201, so that the batch of shelves are all moved upward into the upper space of the independent compartment 201.

[0030] The next batch of unmanned freight vehicles then moves along platform 11 into the independent compartment 201 of the freight elevator car 2. When the identification sensor on the bottom of the unmanned freight vehicle identifies the corresponding second positioning sticker 52 on the independent compartment 201, it indicates that the shelf on the unmanned freight vehicle has been aligned to the designated position on the independent compartment 201. At this time, the unmanned freight vehicle only needs to unload the shelf and place it at the bottom of the independent compartment 201 to complete the loading work of the shelf. After that, the unmanned freight vehicle leaves the freight elevator car 2 and platform 11. The shelves of this batch are all located in the lower space of the independent compartment 201. The second rewinder 6 then lowers the roller shutter 61 to close the entrance and exit of the freight elevator car 2. The freight elevator car 2 then moves the eight shelves along the electrically controlled lifting slide rail 1 to lift and transport them, which greatly increases the single batch of shelf transport capacity of the freight elevator car 2. In addition, the freight elevator car 2 is divided into four entrances and exits for loading and unloading shelves, which greatly improves the loading and unloading efficiency of shelves in the freight elevator car 2.

[0031] Example 2, based on Example 1, such as Figures 1-7 As shown, a first electric rotator 41 is installed on the front side and the rear side of the through slot 301 of the two lifting partitions 3; a first flap 42 is fixedly connected to the rotating part of each of the two first electric rotators 41, and the first flap 42 is initially in a horizontal state tightly against the surface of the lifting partition 3; a second electric rotator 43 is installed on the bottom of each of the two independent compartments 201 of the freight elevator car 2, located on the front side and the rear side of the transverse partition 22; a second flap 44 is fixedly connected to the rotating part of each of the two second electric rotators 43, and the second flap 44 is initially in a horizontal state tightly against the bottom of the independent compartment 201; an anti-collision pad 23 is fixedly connected to the front side and the rear side of each of the two transverse partitions 22.

[0032] When the transport rack is equipped with casters, it is more likely to slide and collide during transportation. When the unmanned freight vehicle places the rack on the lifting partition 3 according to the above steps, it places the rack close to the surface of the anti-collision pad 23 on the same side as the horizontal partition 22. At this time, the first flip plate 42 is aligned with the bottom edge structure of the rack on the side close to the anti-collision pad 23. After the unmanned freight vehicle leaves the freight elevator car 2, the first electric rotator 41 drives the first flip plate 42 to flip up, so that the first flip plate 42 is erected on the side of the bottom edge structure of the rack away from the anti-collision pad 23, so that the bottom edge structure of the rack is limited between the first flip plate 42 and the anti-collision pad 23. Then, the first winding machine 31 pulls the steel wire rope 32 to lift the lifting partition 3, so that the lifting partition 3 moves the rack upward to the upper space of the independent compartment 201 corresponding to the freight elevator car 2.

[0033] Then, the next unmanned freight vehicle places the shelf on the bottom of the elevator car 2 following the above steps. The shelf is located in the lower space of the corresponding independent compartment 201, and the shelf is also close to the surface of the anti-collision pad 23 on the same side as the transverse partition 22. At this time, the second flap 44 is aligned with the bottom edge structure of the shelf near the anti-collision pad 23. After the unmanned freight vehicle leaves the elevator car 2, the second electric rotator 43 drives the second flap 44 to flip up, so that the second flap 44 is erected on the side of the bottom edge structure of the shelf away from the anti-collision pad 23. This limits the bottom edge structure of the shelf between the second flap 44 and the anti-collision pad 23. In the subsequent transportation steps of the elevator car 2, the upper shelf is limited and fixed between the first flap 42 and the anti-collision pad 23, and the lower shelf is limited and fixed between the second flap 44 and the anti-collision pad 23, which greatly reduces the phenomenon of the shelf sliding and colliding in the independent compartment 201.

[0034] Example 3, based on Example 1, such as Figures 1-8 As shown, each of the two roller shutter doors 61 has several observation slots 6101; the bottom of each of the two second winding machines 6 is equipped with an image recognition sensor 62 for monitoring the freight conditions inside the two independent compartments 201 of the freight elevator car 2. The image recognition sensor 62 has a built-in alarm system; a secondary control panel 63 is installed on the freight elevator car 2; several intercepting baffles 24 are fixedly connected to the upper parts of the front and rear sides of the freight elevator car 2; a limiting baffle 33 is fixedly connected to the lower parts of the front and rear sides of the two lifting partitions 3; slots 202 corresponding to the number and position of the limiting baffles 33 are opened at the bottom of the independent compartments 201 of the freight elevator car 2, and the limiting baffles 33 are initially inserted into the corresponding slots 202; a height measuring sensor 34 is installed on the bottom front side and the bottom rear side of the two lifting partitions 3.

[0035] When the total height of the shelving is high, the center of gravity of the shelving also increases, increasing the risk of tipping over during lifting and transportation. After the unmanned freight vehicle places the shelving on the lifting partition 3 according to the above steps, the unmanned freight vehicle leaves the freight elevator car 2. The first winding machine 31 pulls the steel wire rope 32 to lift the lifting partition 3 upward, causing the lifting partition 3 to move the shelving upward to the upper space of the independent compartment 201 corresponding to the freight elevator car 2. At this time, the upper shelf on the lifting partition 3 is roughly aligned with the intercepting baffle 24 in the height direction, and the intercepting baffle 24 protects the upper shelf. On the side away from the transverse partition 22, the next unmanned freight vehicle places the shelf on the inner bottom of the freight elevator car 2 following the above steps. The shelf is located in the lower space of the corresponding independent compartment 201. The unmanned freight vehicle leaves the freight elevator car 2. At this time, the height sensor 34 at the bottom of the lifting partition 3 measures the distance between it and the top of the lower shelf, and the first winding machine 31 releases the steel wire rope 32 downward, so that the lifting partition 3 moves downward and close to the top of the lower shelf under the action of gravity, and the limiting baffle 33 on the lifting partition 3 protects the lower shelf on the side away from the transverse partition 22.

[0036] In the subsequent transportation steps where the freight elevator car 2 moves the shelves, the intercepting baffle 24 and the limiting baffle 33 can respectively provide anti-tipping protection for the transported shelves. At the same time, the image recognition sensor 62 observes whether there is any accidental tipping of the upper or lower shelves. If the image recognition sensor 62 detects that a shelf has tipped over and is against the nearby roller shutter door 61, the electric lifting slide rail 1 controls the freight elevator car 2 to descend back to the first floor position. At the same time, the image recognition sensor 62 notifies the administrator to handle the situation through the built-in alarm system. After the freight elevator car 2 descends and stops at the designated position of the electric lifting slide rail 1, the... The second rewinder 6 will not actively control the roller shutter 61 to rise and open. At this time, the manager can check the specific location of the tilted shelf in the independent compartment 201 through the observation slot 6101 of the roller shutter 61, and slowly control the second rewinder 6 to drive the roller shutter 61 to rise slowly through the secondary control panel 63, so that the lower end of the roller shutter 61 is rolled up to be below the tilted shelf area, so that the manager has enough space to pass through the area below the roller shutter 61 to enter the independent compartment 201. At the same time, the roller shutter 61 provides support for the tilted shelf, making it easy for the manager to manually right the tilted shelf.
