Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0034] Example 1, by Figures 1 to 6 As shown, this embodiment of the present invention provides an automated guided vehicle 1 for bidirectional transport, comprising a trolley assembly 6 capable of moving along a first preset trajectory, a moving assembly 7 and a telescopic assembly 8 engaged with the trolley assembly 6, and a connecting assembly 9 engaged with the telescopic assembly 8. Preferably, the trolley assembly 6 is provided with a transport channel arranged along a second preset trajectory. The moving assembly 7, the telescopic assembly 8, and the connecting assembly 9 are all located in the transport channel.
[0035] The movable component 7 supports the object to be transported and is configured to move the object along a second preset trajectory relative to the trolley component 6 in both the forward and reverse directions. Specifically, the second preset trajectory is a trajectory set on the trolley component 6. In this embodiment, the trolley component 6 is an RGV trolley, and the second preset trajectory is a trajectory perpendicular to the movement direction of the RGV trolley. In other embodiments, the trolley component 6 may be other similar trolleys, and this invention does not specifically limit this. This design, through an integrated transport channel layout, ensures coordinated operation between the various components, not only improving space utilization but also simplifying structural design and facilitating later maintenance and upgrades.
[0036] The telescopic assembly 8 includes a first movable arm 18 movably engaged with the trolley assembly 6, and a first drive member for driving the first movable arm 18 to move. A connecting assembly 9 is engaged with the first movable arm 18 and configured to engage with the object to be transported. The first movable arm 18 is adapted to extend the trolley assembly 6 forward or backward along a second preset trajectory. The first movable arm 18 engages with two of the connecting assemblies 9, which are respectively used to engage with the object to be transported when the first movable arm 18 extends forward and backward from the trolley assembly 6.
[0037] This invention relates to an automated guided vehicle (AGV) 1 for bidirectional transport, suitable for heavy-duty, short-travel transport. Compared to RGV (Automated Guided Vehicle) carriers, this AGV significantly reduces redundant mechanisms and substantially improves cargo movement efficiency. The bidirectional movable first arm 18 enables the vehicle to efficiently perform bidirectional transport operations along a preset trajectory, moving the pallet 3 in both directions, eliminating the need for the steering action of the trolley assembly 6, and improving operational flexibility and efficiency.
[0038] Based on the above embodiments, in an optional embodiment of the present invention, such as... Figure 3 and Figure 6 As shown, the telescopic assembly 8 further includes a fixed arm 16 engaged with the trolley assembly 6, and a second movable arm 17 movably engaged with the fixed arm 16. A first movable arm 18 is movably engaged with the second movable arm 17. A first drive member is drivenly connected to the second movable arm 17 to drive the second movable arm 17 to move forward and backward along the second preset trajectory. The first movable arm 18 is configured to move relative to the second movable arm 17 along its direction of movement when the second movable arm 17 moves. This bidirectional extension design allows the transport vehicle to engage and transport goods from two directions, reducing the steering requirements of the trolley assembly 6 and thus improving handling efficiency.
[0039] Preferably, the first driving member drives the second movable arm 17 to move via a gear and rack structure. The telescopic assembly 8 further includes a first rack engaged with the first movable arm 18, a transmission member engaged with the second movable arm 17, and a second rack engaged with the fixed arm 16. The first rack and the second rack respectively mesh with the transmission member so that when the second movable arm 17 moves, they drive the first movable arm 18 to move relative to the second movable arm 17 along the moving direction of the second movable arm 17.
[0040] In this embodiment, the transmission component is a gear or a chain. When the transmission component is a gear, the gear is rotatably engaged with the second movable arm 17. When the transmission component is a chain, the chain is slidably engaged with the second movable arm 17. Specifically, the chain has a ring structure; the first rack and the second rack mesh with the upper and lower surfaces of the ring structure, respectively. Whether a gear or a chain is used as the transmission component, it can effectively transmit power to the movable arm. The design of the ring chain structure makes the power transmission more continuous and stable.
[0041] The two-section movable arm design increases the telescopic distance of the telescopic component 8, thereby moving the pallet 3 to a more distant location or pulling the pallet 3 from a more distant location onto the automated guided vehicle, enabling the transport vehicle to adapt to the needs of handling over longer distances and improving the coverage and efficiency of the operation.
[0042] Based on the above embodiments, in an optional embodiment of the present invention, such as Figure 3 , Figure 5 and Figure 6 As shown, the moving component 7 includes a fixed base 14, a plurality of rollers 13 spaced apart and rotatably engaged with the fixed base 14, and a second drive member for driving the rollers 13 to rotate. Preferably, the automated guided vehicle 1 includes two moving components 7. The two moving components 7 are respectively disposed on both sides of the telescopic component 8.
[0043] Multiple rollers 13 spaced apart can both support and drive the pallet 3. This allows for more stable and efficient handling of goods, especially when simultaneous handling from both sides is required. Furthermore, the two moving components 7 can align with the external support device 2, thereby transferring the pallet 3 from the transport vehicle to the external support device 2, or vice versa.
[0044] Based on the above embodiments, in an optional embodiment of the present invention, such as Figure 3 and Figure 6As shown, the connecting assembly 9 includes a first limiting member 20 that is retractably engaged with the first movable arm 18, and a third driving member 21 for driving the first limiting member 20 to move. There are two first movable arms 18. The two first movable arms 18 are spaced apart. The connecting assembly 9 also includes a connecting member 19 engaged with the two first movable arms 18. The first limiting member 20 and the third driving member 21 are engaged with the connecting member 19. Preferably, the object to be transported is a tray 3 provided with a traction hole. The first limiting member 20 at least includes a limiting portion capable of being inserted into the traction hole.
[0045] Preferably, the pallet 3 is provided with multiple traction holes at intervals. This structural design allows the telescopic component 8 to flexibly engage and disengage with the object to be transported, improving the convenience and adaptability of operations, and providing more flexible and precise cargo positioning capabilities, especially when handling pallets 3 with specific structures, ensuring the stability and safety of the cargo.
[0046] Based on the above embodiments, in an optional embodiment of the present invention, such as Figure 4 and Figure 6 As shown, the automated guided vehicle 1 further includes an auxiliary component engaged with the trolley assembly 6. The auxiliary component is adapted to confine the object to be transported within the trolley assembly 6. The auxiliary component includes a plurality of retractable first blocking members. The first blocking members are configured to limit the range of motion of the object to be transported on the trolley assembly 6 when extended. In this embodiment, the plurality of first blocking members are respectively disposed at both ends of the moving assembly 7. The first blocking member includes a retractable second limiting member 11 engaged with the moving assembly 7, and a fourth driving member 10 for driving the second limiting member 11 to move. Preferably, the auxiliary component further includes a plurality of guide wheels 12 disposed on both sides of the transport channel along a second preset trajectory.
[0047] The addition of auxiliary components enhances the transport vehicle's ability to control cargo, especially in high-speed or complex environments, ensuring cargo stability and safety and reducing the risk of movement and damage during handling.
[0048] Example 2: This application also provides a bidirectional automated guided transport system, which includes a support device 2 and a bidirectional automated guided transport vehicle 1 as described in any section of Example 1.
[0049] The support device 2 includes at least two support members 4 for supporting the object to be transported. A traction channel 5 is provided between the at least two support members 4 for the movement of the telescopic assembly 8 and the connecting assembly 9. The support members 4 are adapted to roll and support the object to be transported.
[0050] In this embodiment, the support member 4 is provided with a plurality of non-powered rollers 13 at intervals. When the tray 3 moves onto the support member 4, it is moved by the telescopic member. In other embodiments, the rollers 13 of the support member 4 can be driven to the drive member to actively drive the tray 3 to move.
[0051] Preferably, the support device 2 further includes a second blocking member disposed at the end of the support member 4. The second blocking member enables the tray 3 to be positioned. Preferably, the support device 2 further includes a fixing member; the fixing member is adapted to fix the tray 3. The fixing member is an electromagnet or a positioning pin.
[0052] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
