[0001] This utility model relates to the field of warehousing and logistics technology, and in particular to a mother-daughter type flying box car track changing device and warehousing system. Background Technology
[0002] In the field of warehousing and logistics, the fly-box cart (also known as a fly-box truck) is an automated device used for high-speed transport of boxes between rack aisles, and is widely used in automated storage and retrieval systems (AS / RS). Fly-box carts typically run along pre-defined tracks within the aisles to perform the tasks of storing, retrieving, and moving boxes, thereby improving the automation level and operational efficiency of the warehousing system. Each aisle is equipped with a corresponding fly-box cart, enabling independent control and efficient management of the boxes.
[0003] However, existing flying car designs are typically based on fixed lane structures, meaning each flying car can only operate within a designated lane and cannot flexibly switch between multiple lanes. In scenarios with uneven lane traffic or low overall traffic volume, this design can lead to some flying cars remaining idle for extended periods, resulting in low resource utilization and hindering the improvement of overall system scheduling efficiency.
[0004] Therefore, there is an urgent need to propose a mother-daughter type flying box car track changing device and storage system to solve the above-mentioned technical problems. Utility Model Content

[0043] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0044] like Figures 1-4 As shown, this embodiment provides a storage system, including multiple shelves 200 and a mother-daughter type flying box car track changing device.
[0045] Multiple racks 200 are arranged at intervals, and aisles 100 are formed between adjacent racks 200. The mother-daughter type flying box car track changing device includes a first track 1, a second track 2, a mother car 3 and a daughter car 4. The daughter car 4 can move and change between multiple aisles 100.
[0046] like Figure 1 As shown, each aisle 100 is provided with a first track 1, each first track 1 is connected to the corresponding shelf 200 and extends along the length direction of the aisle 100. Second tracks 2 are provided on the outer side of the ends of the multiple aisles 100, and the second tracks 2 extend along a first direction, which is perpendicular to the length direction of the aisle 100.
[0047] The mother car 3 is movably mounted on the second track 2 and can reciprocate along the second track 2. The daughter car 4 has a first position state and a second position state, and can switch between the first position state and the second position state. When the daughter car 4 is in the first position state, the daughter car 4 is connected to the mother car 3 and can reciprocate along the second track 2 together with the mother car 3. When the daughter car 4 is in the second position state, the daughter car 4 can reciprocate along one of the first tracks 1.
[0048] In practice, when there is no need to move or retrieve the boxes within the shelf 200, the trolley 4 is in the first position, i.e., the trolley 4 is connected to the mother car 3. When it is necessary to work in a certain aisle 100, the mother car 3 carrying the trolley 4 is first moved along the second track 2 to the entrance of the aisle 100 and positioned. Then, the trolley 4 leaves the mother car 3 and enters the aisle 100 and moves along the first track 1 within the aisle 100 (i.e., at this time, it switches to the second position) so that the trolley 4 can move and retrieve the boxes within the corresponding shelf 200 in the aisle 100. After the trolley 4 finishes its work in the aisle 100, it returns to the mother car 3 and can move with the mother car 3 to work again in another aisle 100.
[0049] by Figure 1 The directions shown are used as an example for explanation. For ease of description, Figure 1 The multiple lanes 100 shown are sequentially named from top to bottom as Lane 1, Lane 2, Lane 3, Lane 4, etc. For example, when work needs to be performed in Lane 1, the mother car 3 carrying the daughter car 4 moves along the second track 2 to the entrance of Lane 1 and positions itself. Then, the daughter car 4 leaves the mother car 3 and enters Lane 1. The daughter car 4 moves along the first track 1 within Lane 1 to perform the work. After completing the work, the daughter car 4 returns to the mother car 3 to await the next work. For instance, if the next work is to be performed in Lane 2, the mother car 3 moves from the entrance of Lane 1 to the entrance of Lane 2, and then the daughter car 4 enters Lane 2 to perform the work. If the next work is to be performed in Lane 4, the mother car 3 can move directly from the entrance of Lane 1 to the entrance of Lane 4, and then the daughter car 4 enters Lane 4 to perform the work. In other words, the daughter car 4 can switch between any two lanes 100 via the mother car 3.
[0050] The mother-daughter type flying box car track-changing device provided in this embodiment, through the combined structure design of the mother car 3 and the daughter car 4, allows the daughter car 4 to be carried by the mother car 3 and move on the second track 2, and separate at the entrance of any designated lane 100 to enter the target lane for operation. This enables the daughter car 4 to not only complete the task of transporting and storing the material box in a single lane 100, but also to flexibly switch between multiple lanes 100, significantly improving the operating flexibility and adaptability of the flying box car in multi-lane scenarios.
[0051] The warehousing system provided in this embodiment adopts the above-mentioned mother-daughter car type flying box car track changing device, which enables the same daughter car 4 to be dynamically scheduled between multiple lanes 100 according to the task. This avoids the problem of flying box cars being idle for a long time in some lanes 100 and wasting resources, and is conducive to improving the utilization rate of warehousing resources and overall scheduling efficiency.
[0052] like Figure 1 and Figure 2 As shown, in some embodiments, the mother car 3 includes a mother car body 31 and a docking track 32. The mother car body 31 and the docking track 32 are connected to each other. The docking track 32 is always parallel to the first track 1 and can dock with one of the first tracks 1.
[0053] When the mother car 3 moves along the second track 2, the mother car body 31 and the docking track 32 move synchronously. When the mother car 3 moves to the entrance of a certain tunnel 100, the docking track 32 will dock with the first track 1 in that tunnel 100 to form a continuous track. This arrangement allows the daughter car 4 to smoothly transition from the docking track 32 on the mother car 3 to the first track 1 in the tunnel 100, or return from the tunnel 100 to the mother car 3, achieving a stable transition for the daughter car 4 and effectively avoiding problems such as poor operation or jamming caused by track misalignment or gaps.
[0054] like Figure 2 and Figure 3 As shown, in some embodiments, the subcar 4 is provided with a current collector arm 5, and the subcar 4 is configured to be electrically connected to the mother car 3 through the current collector arm 5.
[0055] With this setup, the collector arm 5 can ensure that the power supply is not interrupted when the daughter car 4 moves onto the mother car 3, avoiding problems such as system interruption or restart due to power failure during roadway switching, which is conducive to improving the operational continuity of the fly-box car.
[0056] Furthermore, two current collector arms 5 are provided, and the two current collector arms 5 are spaced apart along the extension direction of the first track 1 on the subcar 4. The design of the double current collector arms effectively expands the electrical connection contact range between the subcar 4 and the mother car 3. If one current collector arm 5 has poor contact or fails, the other current collector arm 5 can still maintain electrical connection, which helps to maintain a good electrical contact state between the subcar 4 and the mother car 3.
[0057] like Figure 1 and Figure 2 As shown, in some embodiments, the second track 2 includes a first guide rail 21 and a second guide rail 22. The first guide rail 21 and the second guide rail 22 are spaced apart and parallel to each other along the length of the roadway 100. The opposite ends of the mother car 3 are respectively movably connected to the first guide rail 21 and the second guide rail 22.
[0058] With this setup, the first guide rail 21 and the second guide rail 22 can support both ends of the mother car 3, forming a double-rail support, which helps to improve the balance and running stability of the mother car 3 when moving along the second rail 2, and avoids tilting or swaying caused by single-rail guidance.
[0059] Furthermore, such as Figure 4 As shown, in some embodiments, two first guide rails 21 and two second guide rails 22 are respectively provided. The two first guide rails 21 and the two second guide rails 22 are all arranged at intervals in the vertical direction. The two opposite ends of the top of the mother car 3 are respectively movably connected to the upper first guide rail 21 and the second guide rail 22, and the two opposite ends of the bottom of the mother car 3 are respectively movably connected to the lower first guide rail 21 and the second guide rail 22.
[0060] This design, with the upper and lower guide rails working together to constrain the mother car 3, provides multi-point guidance and support, further improving the mother car 3's attitude stability and anti-overturning ability during operation.
[0061] like Figure 4 As shown, multiple tracks 1 can be spaced out vertically. This allows the trolley 4 to operate at different heights on the shelf 200.
[0062] In some embodiments, a sliding contact line is provided on the second track 2, which is used to supply power to the second track 2. The sliding contact line power supply method has the advantages of simple structure, strong power supply continuity, and convenient maintenance, and is especially suitable for high-frequency, multi-lane switching working scenarios.
[0063] In some embodiments, the mother vehicle 3 has a first roller that is rotatably connected to the second track 2. The daughter vehicle 4 has a second roller that is rotatably connected to the first track 1.
[0064] By using a rolling connection, the running resistance of the mother car 3 and the daughter car 4 can be reduced when they move. At the same time, the rolling connection has low friction, which helps to reduce component wear and extend the service life of the system.
[0065] Of course, in other embodiments, the connection between the mother car 3 and the second track 2, and between the daughter car 4 and the first track 1, can also be configured in other ways, such as a sliding connection, depending on the actual situation.
[0066] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
