Description

Technical Field

[0001] This utility model relates to the field of maintenance technology for automated warehouse shuttle cars, specifically to an automated warehouse shuttle car transfer device and an automated warehouse shuttle car system. Background Technology

[0002] In an automated storage and retrieval system (AS / RS) shuttle system, when the shuttle is being maintained, it needs to be moved from the AS / RS to the outside of the AS / RS and then put back into the AS / RS for use after maintenance.

Detailed Implementation

[0035] Reference will now be made in detail to embodiments of the present disclosure, one or more of which are set forth herein. Each embodiment and example is provided by way of explanation of the apparatus, composition, and materials of the present disclosure, and not by way of limitation. Rather, the following description provides convenient illustrations for implementing exemplary embodiments of the present disclosure. Indeed, it will be apparent to those skilled in the art that various modifications and variations can be made to the teachings of the present disclosure without departing from the scope or spirit of the present disclosure.

[0036] like Figures 1-7 As shown, this invention discloses a vertical warehouse shuttle transfer device, including a transfer trolley 1, a lifting mechanism for adjusting the height of the transfer trolley 1, and a lifting mechanism for moving the shuttle into and out of the warehouse by lifting the transfer trolley 1 to a height corresponding to the position of the shuttle in the vertical warehouse. The lifting mechanism includes a vertical guide rail 2 arranged parallel to the height direction of the column, a roller assembly 3 slidably arranged on the vertical guide rail 2, the roller assembly 3 and the transfer trolley 1 being detachably connected, and a lifting component for pulling the transfer trolley to move up and down is fixedly arranged on the upper part of the vertical guide rail 2.

[0037] This invention uses a lifting component to elevate the transfer trolley 1 along the vertical guide rail 2 to the same height as the shuttle car in the automated storage and retrieval system. This allows the shuttle car to be transferred from the system to the transfer trolley 1, then lowered as a whole, and finally transported to the corresponding maintenance area via the transfer trolley 1. Alternatively, the transfer device of this invention can be used to reinsert the shuttle car into the automated storage and retrieval system. To ensure the shuttle car can smoothly enter the transfer trolley 1, such as... Figure 6 and Figure 7 As shown, the transfer trolley 1 of this utility model includes two walking guide rails 19 with a width consistent with the track of the shuttle car on the corresponding vertical warehouse. The walking guide rails 19 are fixed together by a connecting beam 20 set on the lower surface of the walking guide rails. Casters 21 are set at the bottom of the connecting beam 20. A lifting mechanism that cooperates with the lifting end of the lifting component is set above the walking guide rails 19. The lifting mechanism includes a lifting beam 22, lifting side plates 23 set at both ends of the lifting beam 22 for fixing the lifting beam 22 to the traveling guide rail 19, and a lifting ring 24 set in the middle of the lifting beam 22. The lifting beam 22 is set above the traveling guide rail 19 along a track direction perpendicular to the traveling guide rail 19. The lifting side plates 23 are fixedly installed at the ends of the lifting beam 22 and are fixedly connected to the outer side of the traveling guide rail 19 at the bottom. During lifting, the lifting ring 24 can be pulled directly. The lifting beam 22 can be set in the middle of the transfer trolley to balance the stress generated at the joint by the gravity of the transfer trolley 1 during lifting, ensuring the stability and uniform force distribution during the lifting process, reducing local stress concentration, and improving the overall service life of the equipment.

[0038] In an embodiment of this utility model, the lifting assembly includes a mounting frame 27 and a winch 28 and a rope pulley 29 mounted on the mounting frame 27. The rope pulley 29 assists the winch 28 in winding and unwinding the winch rope 30. The winch rope 30 is made of steel wire rope and has a hook 31 connected to its end. The hook 31 is used to lift the transfer trolley 1. Alternatively, other mature lifting equipment in the prior art can be used, as long as it can stably lift the transfer trolley 1.

[0039] For the movement of the transfer trolley 1, the trolley can be moved by itself using electronic control equipment. However, in order to save equipment costs, it can also be pulled manually. In this case, a handle 25 for pulling the transfer trolley 1 needs to be installed on the transfer trolley 1. The handle 25 is connected to the transfer trolley 1 through a column 26 at the end, so as to facilitate personnel to pull the transfer trolley 1 to move.

[0040] During the installation of the transfer trolley 1, it is necessary to complete the docking with the roller assembly. The roller assembly 3 of this utility model includes two opposing roller mounting plates 4, which are connected by a support beam 5 arranged perpendicular to the vertical guide rail. Roller sets that cooperate with the corresponding surfaces of the vertical guide rail 2 are provided on the roller mounting plates 4, and the roller assembly 3 is moved by the roller sets. An upper stop block 9 and a lower stop block 10 are provided on the vertical guide rail 2, and the upper stop block 9 and the lower stop block 10 cooperate with the roller mounting plates 4 to limit the up and down movement of the roller assembly 3. The roller mounting plate 4 and the transfer trolley 1 are detachably connected by a pin docking mechanism 11. The pin docking mechanism 11 includes a pin 12 on the transfer trolley 1, a docking sleeve 13 on the roller mounting plate 4 for cooperating with the pin 12, and a locking pin 14 on the roller mounting plate 4 for locking after the pin 12 and the docking sleeve 13 are connected. Both the docking sleeve 13 and the pin 12 are provided with pin holes that cooperate with the locking pin.

[0041] The roller mounting plate 4 of this utility model has a locking pin sleeve 15. The locking pin 15 is slidably inserted inside the locking pin sleeve 15. A locking pin handle 16 is fixedly connected along the axis perpendicular to the locking pin 14 for sliding operation of the locking pin 14 outside the locking pin sleeve 15. A groove 17 for moving the locking pin handle 16 is correspondingly formed on the wall surface of the locking pin sleeve 15. Horizontal slots communicating with the groove 17 are formed along the circumferential direction at both the upper and lower parts of the groove 17. 18. By rotating the locking pin handle 16 into the horizontal slot 18, the locking pin 14 is axially limited and fixed in the locking pin sleeve 15. The locking pin sleeve 15 structure of this utility model can take into account both the movement guidance and limiting functions of the locking pin 14. It can quickly insert the locking pin 14 into the pin hole to complete the docking between the transfer trolley 1 and the roller mounting plate 4, and can also prevent the locking pin 14 from disengaging from the pin hole, thereby improving the reliability of the docking part during the lifting process and ensuring operational safety.

[0042] To facilitate the alignment between the pin 12 and the pin hole, and to quickly complete the docking of the transfer trolley 1 and the roller mounting plate 4, the roller assembly 3 of this utility model is provided with a limiting structure for limiting the position of the transfer trolley during docking. The limiting structure is used to position the transfer trolley. It can be directly set with a limiting block or a block structure with adjustable length to adapt to the positioning requirements of transfer trolleys of different specifications. Those skilled in the art can choose according to their needs. It only needs to cooperate with the body of the transfer trolley 1 to limit the movement of the transfer trolley.

[0043] After the transfer trolley 1 is connected to the roller mounting plate 4 via the pin docking mechanism 11, the transfer trolley 1 is lifted by the lifting assembly. Simultaneously, the roller assembly 3 moves along the vertical guide rail 2 to assist in lifting the transfer trolley. The cooperation between the roller assembly 3 and the vertical guide rail 2 maintains the stability of the lifting of the transfer trolley 1. The vertical guide rail 2 needs to bear part of the force generated by the lifting of the transfer trolley 1. The vertical guide rail 2 of this invention adopts a C-shaped steel structure. C-shaped steel structures have the advantages of high strength, high rigidity, good stability, and good bending resistance, which can meet the usage requirements. Furthermore, finished products can be directly used for assembly, reducing the overall installation complexity of the device. To reduce assembly difficulty, this utility model's roller assembly includes a transverse roller that mates with the outer wall of the C-shaped groove of the vertical guide rail 2, and a side guide roller 6 that mates with the bottom of the C-shaped groove of the vertical guide rail 2. The mating clearance between the corresponding roller and the surface of the vertical guide rail 2 determines the stability of the roller assembly 3 moving along the vertical guide rail 2. This utility model adjusts the position of the transverse rollers at at least on one side wall of the roller mounting plate 4, which are at the same height. By changing the horizontal position of the transverse rollers on the roller mounting plate 4, the spacing between the two transverse rollers at the same height can be adjusted, thereby reducing the impact of the machining dimensional accuracy of the assembled components on the assembly process.

[0044] like Figures 2-5 As shown in the embodiment of this utility model, the horizontal roller that is fixed in position with the roller mounting plate 4 is referred to as the fixed horizontal roller 7, and the horizontal roller that is adjustable in position on the roller mounting plate 4 is referred to as the tensioning horizontal roller 8. The roller mounting plate 4 is provided with an oblong mounting hole at the mounting position of the tensioning horizontal roller 8, which cooperates with the rotating shaft of the tensioning horizontal roller 8. The horizontal position of the tensioning horizontal roller 8 is adjusted by changing the cooperation position between the rotating shaft of the tensioning horizontal roller 8 and the oblong mounting hole. The horizontal rollers on the same side wall of the vertical guide rail 2 are arranged in an alternating manner of fixed horizontal roller 7 and tensioning horizontal roller 8. The single roller mounting plate 4 of this utility model has a total of 4 horizontal rollers, which are set at the four corners of the roller mounting plate. The fixed horizontal rollers 7 and the tensioning horizontal rollers 8 are diagonally distributed. The diagonal fixed horizontal rollers 7 limit the installation angle deviation of the roller assembly on the vertical guide rail 2. Only the position of the tensioning horizontal rollers 8 at the corresponding height needs to be adjusted. The assembly operation is simple, and there is no need to consider the lateral adjustment distance of each tensioning horizontal roller 8. It is only necessary to ensure that the rollers are pressed against the surface of the vertical guide rail.

[0045] This utility model's automated storage and retrieval system (AS / RS) shuttle transfer device is mainly applied to AS / RS shuttle systems. It connects to the end column of the AS / RS storage unit via a vertical guide rail 2, thus fixing the transfer device to the AS / RS storage unit. Based on the functions achieved by the transfer device, it can be applied to other scenarios requiring shuttle movement without departing from the protection scope of this utility model. In use, the transfer trolley 1 and roller mounting plate 4 are assembled via a trolley pin docking structure. Then, the lifting assembly lifts the transfer trolley 1 to a height corresponding to the shuttle's track. The shuttle moves out of the AS / RS and onto the transfer trolley 1's guide rail 19. The lifting assembly then lowers the transfer trolley 1 and shuttle as a whole until the casters 21 contact the ground. The pin docking mechanism 11 is then opened to detach the transfer trolley 1 from the roller mounting plate 4, allowing the transfer trolley 1 to move freely and transport the shuttle to the desired location. Similarly, the shuttle can be moved back into the AS / RS using the reverse process.
