Abstract
Description
Technical Field
[0001] This invention relates to the field of automated logistics technology, and in particular to a fabric transport vehicle. Background Technology
[0002] With the development of automation technology, AGVs, as the core equipment of automated logistics systems, have been widely used in material handling, sorting, and loading / unloading processes across various industries. In the textile industry, fabrics are often stored and circulated in rolls or bundles. In automated logistics systems, AGVs can be used for automated handling of fabrics, effectively improving logistics efficiency and reducing labor costs.
[0003] However, when traditional AGVs are directly applied to fabric handling scenarios, they still face significant technical challenges. Since the output position of textile machines is usually low, the AGV needs to back up after receiving the fabric and then raise it. Because the fabric itself is heavy, the overall center of gravity of the AGV shifts forward, making it prone to tipping forward when starting due to the shift in the center of gravity. This not only affects the reliability of the handling task but also poses a safety hazard. Summary of the Invention

[0029] Existing AGV vehicles pose a risk of tipping forward when transporting fabrics. This application provides a fabric transport vehicle that offers stable support during startup, increasing the success rate of transport.
[0030] Specifically, please refer to Figures 1 to 6In some embodiments, the fabric transport vehicle may include a vehicle body 10 and a support device 20. The vehicle body 10 is used to carry and transport fabric. The support device 20 may include a base 21, a support rod 22, and a drive assembly 23. The base 21 is fixed to the vehicle body 10, the support rod 22 is rotatably connected to the base 21, and the drive assembly 23 is fixed to the base 21 and drivably connected to the support rod 22. The support rod 22 has a supported state and a retracted state. When the support rod 22 is in the supported state, it extends downwards at an angle towards the front of the vehicle body 10. When the support rod 22 is in the retracted state, it is located inside the vehicle body 10. The drive assembly 23 can drive the support rod 22 to rotate, allowing the support rod 22 to switch between the supported state and the retracted state.
[0031] Understandably, during the loading of fabric into this fabric transport vehicle, the support rod 22 is rotated forward to a supporting state via the drive assembly 23. When the vehicle body 10 starts and moves backward, if there is a tendency to tilt forward due to the forward shift of the fabric's center of gravity, the support rod 22, in its supporting state, can promptly contact the ground, forming an additional stable support structure. This effectively resists the overturning moment of the entire vehicle, preventing the transport vehicle from tipping forward and significantly improving the success rate and safety of fabric transport operations. After the fabric transport vehicle exits from the textile machine's discharge port and completes the fabric lifting, the center of gravity of the entire vehicle returns to the area within the vehicle body 10. At this time, the support rod 22 is driven to rotate in the opposite direction via the drive assembly 23, causing it to disengage from the supporting state and retract into its storage position within the vehicle body 10. This prevents the support rod 22 from interfering with the ground or other obstacles during subsequent travel of the vehicle body 10, ensuring the flexibility and passability of the vehicle body 10 during movement. In addition, by tilting the support rod, the front end of the support rod 22 is lower in the supported state and higher in the retracted state. This not only prevents the support rod 22 from being worn against the ground when it is opened or retracted, but also prevents the vehicle body 10 from tilting forward at an excessive angle.
[0032] In summary, this application, by setting an actively controllable support device 20, can extend the support rod 22 during the fabric loading and vehicle body 10 start-up phases to provide reliable anti-tipping protection, and can quickly retract the support rod 22 during the vehicle body 10 driving and transfer phases to keep the vehicle body compact, thereby fundamentally eliminating the risk of tipping caused by the forward shift of the center of gravity, while taking into account both mobility and spatial adaptability, and greatly improving the overall reliability of fabric handling.
[0033] Optionally, such as Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, in some embodiments, the base 21 includes a base 211 and a mounting plate 212. The mounting plate 212 is fixed to the base 211 and extends downwardly at an incline toward the front of the vehicle body 10. The drive assembly 23 is fixed to the mounting plate 212, and the support rod 22 is rotatably connected to the mounting plate 212. The rotation axis of the support rod 22 is perpendicular to the mounting plate 212. Thus, the mounting plate 212 has a preset angle that is inclined downwards toward the front of the vehicle body 10, so that the rotation trajectory of the support rod 22 is inclined. When the support rod 22 is in the supported state, the support rod 22 extends downwardly at an incline toward the front of the vehicle body 10 along the extension direction of the mounting plate 212, and the front end of the support rod 22 is close to the ground, so that the support rod 22 can abut against the ground. When the support rod 22 is in the retracted state, the front end of the support rod 22 is away from the ground to avoid interference between the support rod 22 and the ground or other obstacles.
[0034] It is worth noting that when the support rod 22 is in the supported state, if the vehicle body 10 does not tilt forward, the front end of the support rod 22 can maintain a gap of at least 2mm with the ground to avoid friction between the support rod 22 and the ground during rotation.
[0035] Optionally, such as Figure 2 As shown, in some embodiments, the vehicle body 10 includes a chassis 11, which includes a chassis body 111 and an abutment portion 112. A base 21 is fixed to the chassis body 111, and the abutment portion 112 is disposed on the chassis body 111 and located above the support rod 22. When the support rod 22 is in a supported state, the support rod 22 abuts against the abutment portion 112. With this configuration, when the support rod 22 contacts the ground, the abutment portion 112 can serve as a fulcrum for the support rod 22, effectively shortening the actual lever arm length of the support rod 22 and significantly reducing the torque acting on the rear end of the support rod 22 and the drive assembly 23. This protects the drive assembly 23 from overload or damage caused by excessive torque, thereby improving the overall reliability and service life of the support device 20.
[0036] Optionally, such as Figure 2As shown, in some embodiments, a storage compartment 113 is provided on the front side of the chassis 11, and an abutment portion 112 is located above the storage compartment 113. An installation compartment 114 is provided on the upper surface of the chassis 11, and the installation compartment 114 communicates with the storage compartment 113. The base 21 is fixed in the installation compartment 114. When the support rod 22 is in the retracted state, one end of the support rod 22 is located in the installation compartment 114, and the other end is located in the storage compartment 113. When the support rod 22 is in the supported state, the support rod 22 abuts against the chassis 11. In other words, the support rod 22 extends obliquely from the installation compartment 114 into the storage compartment 113, and the upper wall of the storage compartment 113 can form the abutment portion 112. When the support rod 22 is in the supported state, the support rod 22 is driven by the drive assembly 23 to rotate out of the storage compartment 113; when the support rod 22 is in the retracted state, the support rod 22 is driven by the drive assembly 23 to rotate into the storage compartment 113. In this way, the storage compartment 113 can not only provide storage space for the support rod 22, but also form an abutment part 112 on the upper wall of the storage compartment 113, thereby effectively utilizing the space of the chassis 11. In addition, by opening the mounting compartment 114 on the upper surface of the chassis 11, the height of the base 21 can be reduced, making the overall structure of the chassis 11 and the support device 20 more compact, thereby further improving the space utilization rate of the chassis 11.
[0037] Preferably, such as Figure 2 and Figure 3 As shown, in some embodiments, the support device 20 further includes a flexible top block 24, which is fixed to the support rod 22 and located between the support rod 22 and the abutment portion 112. When the support rod 22 rotates to the supported state and abuts against the abutment portion 112, the flexible top block 24 can achieve flexible contact through its own elastic deformation, effectively dispersing local stress and absorbing impact energy. This design can significantly reduce the risk of brittle fracture of the support rod 22 under stress, thereby improving the reliability and service life of the support device 20.
[0038] Optionally, in some embodiments, the flexible top block 24 can be a top block made of other flexible materials such as nylon top block or rubber top block.
[0039] Optionally, such as Figure 2 and Figure 3 As shown, in some embodiments, the support device 20 further includes a pulley 25, which is rotatably disposed at the front end of the support rod 22. The pulley 25 can be used to contact the ground. When the vehicle body 10 retracts and the support rod 22 enters the support state and contacts the ground, the pulley 25 can roll freely with the movement of the vehicle body 10, converting the sliding friction between the support rod 22 and the ground into rolling friction. This reduces the frictional resistance and ground scraping during the movement of the vehicle body 10, effectively reducing the wear of the support rod 22 and the ground, while also making the movement of the vehicle body 10 smoother and more stable.
[0040] Furthermore, when the torque on the support rod 22 is too large, it can easily damage the drive device. Therefore, in some embodiments, the drive assembly 23 includes a transmission assembly and a drive member, with the transmission assembly being tractably connected to the support rod 22 and the drive member. The driving force output by the drive member can be transmitted to the support rod 22 through the transmission assembly, thereby causing the support rod 22 to rotate. In this way, the support rod 22 and the drive rod are tractively connected through the transmission assembly. The transmission assembly, as a mechanical safety barrier that is prioritized for failure, can actively interrupt the transmission of torque to the drive member. Even if the support rod 22 is subjected to a torque exceeding its tolerance range, the transmission assembly can isolate the transmission of torque, eliminating the risk of impact damage to the drive member, thereby effectively protecting the drive member.
[0041] Alternatively, in some embodiments, such as Figure 3 and Figure 5 As shown, the transmission assembly can be implemented as a synchronous belt pulley assembly, which may include two synchronous pulleys 231 and a synchronous belt (not shown) rotatably connected to the two synchronous pulleys 231. The two synchronous pulleys 231 are respectively connected to the support rod 22 and the drive member. When the support rod 22 is subjected to an excessive torque, the synchronous belt, due to its own characteristics, will not transmit the torque to the drive member, thereby protecting the drive member. Alternatively, the transmission assembly can also be implemented as a transmission sprocket assembly.
[0042] Optionally, in some embodiments, the drive element can be implemented as a joint motor module 232, which is drivably connected to the transmission assembly. On one hand, the joint motor module 232 has high integration and a compact structure, saving installation space within the narrow space of the chassis 11, making the overall drive assembly 23 layout simpler and more compact. On the other hand, the motor module can output high torque in a small volume and has excellent control over tightness, speed, and torque, easily driving the powerful torque required to rotate the support rod 22, ensuring that the support rod 22 can reliably switch from the retracted state to the supported state and maintain a stable position under load. Furthermore, the drive element can also be implemented as a drive motor.
[0043] Optionally, such as Figure 2 As shown, in some embodiments, the support device 20 further includes a sensor 26 disposed on the vehicle body 10 and electrically connected to the drive assembly 23. The sensor 26 is used to detect the position of the support rod 22. When the support rod 22 rotates to the position of the supported state or the position of the stored state, the sensor 26 can send a signal to stop the drive assembly 23, ensuring that the support rod 22 can be accurately rotated to the target position.
[0044] Optionally, such as Figure 1As shown, in some embodiments, the fabric transport vehicle includes two sets of support devices 20, which are spaced apart from each other on the vehicle body 10. By providing two sets of support components, the number of support points is increased, avoiding the problem of excessive stress concentration at the connection between the support rod 22 and the drive assembly 23 when using single-point support, thus improving the structural safety and service life of the fabric transport vehicle. Furthermore, the two independent sets of support devices 20 constitute a certain degree of redundancy; when one set of support devices 20 fails, the other set can still provide partial support, maintaining the stability of the vehicle body 10 to a certain extent, enhancing the system's fault tolerance and overall reliability.
[0045] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0046] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
