Description

Technical Field

[0001] The utility model belongs to the field of shuttle vehicles and relates to a two-way connecting shuttle vehicle and a logistics conveying system. Background Art

[0002] For example, a Chinese patent document discloses a transfer and positioning mechanism for a shuttle car in a high-density intelligent warehousing system [202210572554.3]. A movable transfer bracket for the shuttle car is designed so that when the bracket falls from above the shuttle car track to the shuttle car track, it can be adaptively aligned with the shuttle car track, thereby reducing the matching accuracy requirements between the bracket and the shuttle car track. When the shuttle car enters the end track of the shelf, the movable transfer bracket is raised by a forklift, and the shuttle car is positioned and transferred to the movable transfer bracket. The movable transfer bracket carrying the shuttle car is moved to the top of the end track of the target shelf. The fork body falls, so that the movable transfer bracket is adaptively matched with the end track of the target shelf and easily enters the end track of the target shelf. The movable transfer bracket continues to descend, so that the shuttle car is transferred to the end track of the target shelf, completing the transfer of the shuttle car.

[0003] The defects of the above technical solution are: the shuttle car itself lacks the function of bidirectionally connecting materials, and the upper limit of the material it can carry is small, and the shuttle car lacks the function of adjusting its own material displacement.

DETAILED DESCRIPTION

[0024] Example 1, please refer to Figures 1 to 4 , which is a schematic diagram of a bidirectional shuttle vehicle and logistics conveying system provided by the present invention. The bidirectional shuttle vehicle comprises a track conveying assembly 10, two roller conveyors 20 spaced apart on the track conveying assembly 10, and a transverse movement assembly 30 disposed between the two roller conveyors 20. It is conceivable that the bidirectional shuttle vehicle also includes other functional components and specific structures, such as electrical connection components, control components, and mounting structures, all of which are well known to those skilled in the art and will not be described in detail here.

[0025] It should also be noted that, in this embodiment, the conveyed materials are conveyed through a turnover container, which is a rectangular shell with an open upper end. The turnover container is a prior art.

[0026] In this embodiment, the rail conveying assembly 10 is a rail-type shuttle, which specifically includes a transverse guide rail 11 arranged along the length direction. The transverse guide rail 11 has two and is arranged parallel to the ground. A shuttle frame 12 is slidably connected to the transverse guide rail 11. The transverse guide rail 11 is a rectangular cross-sectional structure protruding upward. The upper end and the outer sides of the transverse guide rail 11 are provided with flat surfaces that cooperate with the shuttle frame 12. Specifically, a running wheel 13 is provided at the bottom of the shuttle frame 12 and is slidably arranged at the upper end of the transverse guide rail 11. The running wheel 13 is connected to a self-driving force. A rotating shaft 17 and a frame driver 18 connected to the rotating shaft 17 are hinged at the bottom of the shuttle frame 12. The running wheel 13 has two and is in rolling connection with the upper end of the transverse guide rail 11. The frame driver 18 provides power to the rotating shaft 17 to drive the movement of the running wheel 13. At the bottom of the shuttle frame 12, on both sides of the running wheel 13, there are guide retaining wheels 14 that abut against the side walls of the transverse guide rail 11. The two guide retaining wheels 14 are symmetrically connected to the transverse guide rail 11 to prevent the shuttle frame 12 from deflecting, providing good conditions for the shuttle frame 12 to move at high speed on the transverse guide rail 11. Optimally, the running wheel 13 is sleeved on the rotating shaft 17, and axial retaining blocks 19 are provided on both sides of the rotating shaft 17 on the running wheel 13. The axial retaining blocks 19 stabilize the installation position of the running wheel 13. Optimally, a cleaning brush 15 is also provided at the bottom of the shuttle frame 12 to act on the outer wall of the transverse guide rail 11. The cleaning brush 15 cleans foreign matter and fine dust from the transverse guide rail 11, ensures the cleanliness of the track of the running wheel 13, and increases the smoothness of the displacement of the running wheel 13.

[0027] Matching buffers 16 are provided between the two ends of the transverse guide rail 11 and the two ends of the shuttle frame 12. In this embodiment, the buffer 16 is an electromagnetic block arranged on the transverse guide rail 11 and the shuttle frame 12, which can achieve the purpose of buffering and deceleration by increasing the repulsive magnetic force when the two are close to each other.

[0028] The roller conveyors 20 have two rollers and are spaced apart along the length of the track conveying assembly 10 on the shuttle frame 12. The width of the roller conveyors 20 is similar to that of the shuttle frame 12, avoiding protrusions and reducing space occupation. At the upper end of the roller conveyors 20, there are a number of conveying rollers 21 arranged along the length of the track conveying assembly 10 and spaced apart along the width of the track conveying assembly 10. The conveying rollers 21 are connected to a roller drive, which is a motor. The roller conveyors 20 are designed to feed and discharge materials laterally, and displacement conveying is performed at the material connection or at the upper end of the roller conveyors 20. A guide baffle 34 is provided on the outer side of the two roller conveyors 20. The guide baffle 34 provides movement guidance for the material connection and in and out, preventing the material from escaping from the roller conveyors 20 from the side. The two roller conveyors 20 increase the material carrying capacity of the shuttle frame 12. At the same time, each roller conveyor 20 serves as a single-sided feed and discharge end to achieve the purpose of bidirectional material connection.

[0029] In this embodiment, the roller conveyor 20 is provided with an end baffle 35 on either side of the conveying direction. The end baffles 35 of the two roller conveyors 20 are located at both ends of the conveying direction. The end baffles 35 are used to connect the material to the end abutment on the roller conveyor 20 to prevent the material from leaving the roller conveyor 20 due to inertia.

[0030] In other embodiments, the end baffle 35 may be installed on the roller conveyor 20 using a lifting structure, and the purpose of activation is achieved by lifting the end baffle 35 so that it protrudes from the conveying roller 21.

[0031] The transverse movement assembly 30 includes two mounting notches 31 arranged along the length direction of the track conveying assembly 10 and spaced apart between the two roller conveyors 20, and a lifting platform 32 arranged below the roller conveyors 20. The mounting notches 31 serve as reserved clearance spaces, which are sufficient to allow the lifting platforms 32 to move upward and downward without interference. A chain conveyor 33 that can extend out of the mounting notches 31 is provided on the lifting platform 32. The chain conveyor 33 has two groups. The chain conveyor 33 is supported by a sprocket, and a chain is wound around the outside, as well as a rotating motor that drives the sprocket to rotate. The chain is in direct contact with the turnover container or a conveying deck is provided as a wear-resistant structure. During the transverse movement process, the transverse movement assembly 30 uses the end baffle 35 as a side baffle and the guide baffle 34 as an end block, thereby realizing the material transfer between the two roller conveyors 20 and improving the material transportation efficiency.

[0032] Example 2: The present invention also provides a logistics transportation system having a two-way connecting shuttle as described above. Except for the two-way connecting shuttle, other components are existing technologies or commercially available parts.

[0033] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.
