Description

Technical Field

[0001] This utility model relates to warehousing systems, specifically to a lifting system for goods used in automated warehousing. Background Technology

[0002] In automated storage and retrieval systems (AS / RS), shelves have multiple storage locations from bottom to top, requiring elevators to move goods to different heights. Elevators disclosed in patents CN201620602038.0 and CN202323434526.4 are designed to achieve this function. However, existing elevators of this type only have one loading platform, moving only one container at a time during inbound or outbound operations, resulting in low efficiency. Therefore, a new technical solution is needed to address this problem. Utility Model Content

[0003] Purpose of the utility model: In view of the above-mentioned shortcomings, this utility model provides a cyclic lifting system to improve the efficiency of cargo box inbound and outbound transportation.

[0004] Technical Solution: To solve the above problems, this utility model provides a circulating lifting system, including two outer columns on both sides and a middle column located between the two outer columns. There are two outer columns on each side and at least two middle columns. A lifting channel is formed between the middle column and the outer columns, forming two adjacent lifting channels. There is at least one lifting vehicle in each lifting channel. Two wheels are provided on each side of the lifting vehicle. The wheels have external toothed rings. A first toothed rack is provided on the side of the middle column facing the outer column, and a second toothed rack is provided on the side of the outer column facing the middle column. The external toothed rings of the wheels on both sides of the lifting vehicle mesh with the first toothed rack and the second toothed rack, respectively.

[0005] The top of the two outer columns is equipped with an upper synchronous belt device, which includes two upper synchronous belts. The two upper synchronous belts are fixed with an upper displacement translation slide rail. The upper displacement translation slide rail includes two third racks and two fourth racks. The third racks and fourth racks on the same side are fixed on one upper synchronous belt, and the third racks and fourth racks on the other side are fixed on another upper synchronous belt. When the upper displacement translation slide rail is located in any lifting channel, the third rack is located above the second rack and forms a continuous rack structure with the second rack, and the fourth rack is located above the first rack and forms a continuous rack structure with the first rack.

[0006] The bottom of the two outer columns is equipped with a lower synchronous belt device, which includes two lower synchronous belts. These two lower synchronous belts are fixed with a lower shifting and translational slide rail, which includes two fifth racks and two sixth racks. The fifth and sixth racks on the same side are fixed to one lower synchronous belt, while the fifth and sixth racks on the other side are fixed to the other lower synchronous belt. When the lower shifting and translational slide rail is located within any lifting channel, the fifth rack is located below the second rack and forms a continuous rack structure with it, and the sixth rack is located below the first rack and forms a continuous rack structure with it.

[0007] When the lifting vehicle rises to the top of the lifting channel, the outer toothed rings of the two wheels on both sides of the lifting vehicle mesh with the third and fourth racks respectively. The upper synchronous belt device causes the upper shifting slide rail and the lifting vehicle to move from one lifting channel to another. When the lifting vehicle descends to the bottom of the lifting channel, the outer toothed rings of the two wheels on both sides of the lifting vehicle mesh with the fifth and sixth racks respectively. The lower synchronous belt device causes the lower shifting slide rail and the lifting vehicle to move from one lifting channel to another.

[0008] Furthermore, a pair of first slide rails located above the upper synchronous belt device and a pair of second slide rails located below the upper synchronous belt device are provided. Both ends of the first slide rail and both ends of the second slide rail are fixed on the outer columns on both sides. The third and fourth racks of the upper transposition translation slide rail are provided with pulleys that cooperate with the corresponding first and second slide rails.

[0009] Furthermore, a pair of third slide rails located above the lower synchronous belt device and a pair of fourth slide rails located below the lower synchronous belt device are provided. Both ends of the third slide rail and both ends of the fourth slide rail are fixed on the outer columns on both sides. The fifth and sixth racks of the lower displacement translation slide rail are provided with pulleys that cooperate with the corresponding third and fourth slide rails.

[0010] Furthermore, the upper synchronous belt device also includes two upper synchronous belt pulleys that cooperate with each upper synchronous belt and an upper drive motor. The two upper synchronous belt pulleys are respectively connected to the outer columns on both sides. One of the upper synchronous belt pulleys is the drive pulley, and the drive motor is also installed on the outer column on the same side as the drive pulley and drives the drive pulley to rotate.

[0011] Furthermore, the lower timing belt device also includes two lower timing belt pulleys that cooperate with each lower timing belt and a lower drive motor. The two lower timing belt pulleys are respectively connected to the outer columns on both sides. One of the lower timing belt pulleys is the driving pulley. The lower drive motor is also mounted on the outer column on the same side as the driving pulley and drives the driving pulley to rotate.

[0012] Furthermore, there are four central pillars, two of which, together with two outer pillars on one side, form a lifting channel, and the other two central pillars, together with two outer pillars on the other side, form another lifting channel.

[0013] Furthermore, it also includes an inbound conveyor located on one side of one of the lifting channels, an outbound conveyor located on one side of the other lifting channel, and shelves located on the other side of the two lifting channels.

[0014] Furthermore, the shelving includes several layers of storage locations, with the highest layer being lower than the upper transposition sliding rail; the inbound conveyor and outbound conveyor have only one layer.

[0015] Furthermore, the shelf is equipped with a trolley with forks for picking up and placing goods.

[0016] Furthermore, a front-of-warehouse chain conveyor is provided between the shelving and the two lifting channels. The front-of-warehouse chain conveyor includes multiple layers, with a chain conveyor on each layer, and each layer of chain conveyor corresponds to one layer of storage location.

[0017] Beneficial effects: Compared with the prior art, the advantages of this utility model are that multiple lifting vehicles can be set in two lifting channels, which means that multiple cargo boxes can be carried and moved up and down simultaneously. Moreover, the lifting vehicles can circulate in the two lifting channels, which can improve the transportation efficiency of cargo boxes. The two lifting channels of this lifting system only occupy the space of two cargo positions on the ground, resulting in high space utilization. Attached Figure Description

[0027] like Figures 1 to 3 As shown, this utility model discloses a circulating lifting system, including two outer columns 1 on both sides and an intermediate column 2 located between the two outer columns.

[0028] like Figures 3 to 6 As shown, there are two outer columns 1 on each side, for a total of four outer columns. There are two or four middle columns 2; in this embodiment, four are selected. The two outer columns 1 on the same side are connected to the two middle columns 2 by crossbeams to form a frame structure. The two middle columns and the two outer columns on one side form a lifting channel 3, and the other two middle columns and the two outer columns on the other side form another lifting channel 4. There is at least one lifting vehicle 5 within each lifting channel; generally, to improve cargo transportation efficiency, multiple lifting vehicles 5 are installed and circulate within the two lifting channels.

The side of the middle column 2 facing the outer column 1 has a first rack 21, and the side of the outer column 1 facing the middle column has a second rack 11. The external toothed rings of the two wheels 51 on both sides of the lifting vehicle mesh with the first rack 21 and the second rack 11, respectively. If two intermediate pillars 2 are selected, each intermediate pillar 2 has a first rack 21 on both sides. In this embodiment, since four intermediate pillars 2 are selected, each intermediate pillar 2 has a first rack 21 on only one side.

[0029] The top of the two outer columns 1 is equipped with an upper synchronous belt device 6. The upper synchronous belt device includes two upper synchronous belts 61, two upper synchronous pulleys 62 that cooperate with each upper synchronous belt 61, and an upper drive motor 63. The two upper synchronous pulleys 62 are respectively connected to the two outer columns 1. One of the upper synchronous pulleys is the driving pulley. The drive motor 63 is also mounted on the outer column on the same side as the driving pulley and drives the driving pulley to rotate. The two upper synchronous belts 61 are fixed with an upper transposition translation slide rail 7. The upper transposition translation slide rail 7 includes two third racks 71 and two fourth racks (not shown). The third racks 71 and fourth racks on the same side are fixed on one upper synchronous belt 61, and the third racks 71 and fourth racks on the other side are fixed on another upper synchronous belt 61. When the upper transposition translation slide rail is located in any of the lifting channels, the third rack 71 is located above the second rack 11 and forms a continuous rack structure with the second rack 11, such as... Figure 3As shown. Similarly, the fourth rack is located above the first rack 21 and forms a continuous rack structure with the first rack 21 (not shown). Between the outer columns 1, a pair of first slide rails 12 located above the upper synchronous belt device 6 and a pair of second slide rails 13 located below the upper synchronous belt device 6 are also provided. Both ends of the first slide rail 12 and both ends of the second slide rail 13 are fixed to the outer columns 1 on both sides. The third rack 71 and the fourth rack of the upper transposition sliding slide rail 7 are provided with pulleys 73 that cooperate with the corresponding first and second slide rails. The third rack 71 and the fourth rack are also provided with locking buckles 72 that are fixed to the upper synchronous belt 61.

[0030] like Figure 5 , Figure 7 As shown, corresponding to the upper synchronous belt device, a lower synchronous belt device 8 is provided at the bottom of the outer columns 1 on both sides. The lower synchronous belt device 8 includes two lower synchronous belts 81, two lower synchronous pulleys 82 that cooperate with each lower synchronous belt 81, and a lower drive motor 83. The two lower synchronous pulleys 82 are respectively connected to the outer columns 1 on both sides. One of the lower synchronous pulleys is the driving pulley. The lower drive motor 83 is also installed on the outer column on the same side as the driving pulley and drives the driving pulley to rotate. The two lower synchronous belts 81 are fixed with a lower shifting translation slide rail 9. The lower shifting translation slide rail 9 includes two fifth racks 91 and two sixth racks (not shown). The fifth racks 91 and sixth racks located on the same side are fixed on one lower synchronous belt 81, and the fifth racks 91 and sixth racks located on the other side are fixed on the other lower synchronous belt 81. When the lower shifting translation slide rail 9 is located in any lifting channel, the fifth rack 91 is located below the second rack 11 and forms a continuous rack structure with the second rack 11, such as... Figure 3 As shown. Similarly, the sixth rack is located below the first rack 21 and forms a continuous rack structure with the first rack 21 (not shown). Between the outer columns 1, a pair of third slide rails 14 located above the lower synchronous belt device and a pair of fourth slide rails 15 located below the lower synchronous belt device are also provided. Both ends of the third slide rails 14 and both ends of the fourth slide rails 15 are fixed to the outer columns 1 on both sides. The fifth rack 91 and the sixth rack of the lower shifting slide rail are provided with pulleys 93 that cooperate with the corresponding third and fourth slide rails. The fifth rack 91 and the sixth rack are also provided with latches 92 that are fixed to the lower synchronous belt 81.

[0031] like Figure 6As shown, the principle of the lifting vehicle in the circulating lifting system, which allows it to circulate within two lifting channels, is as follows: When the lifting vehicle 5 rises to the top of one lifting channel 4, the outer toothed rings of the wheels on both sides of the lifting vehicle mesh with the third rack 71 and the fourth rack 72 respectively. The upper synchronous belt device 6 causes the upper shifting slide rail 7 and the lifting vehicle 5 to move from one lifting channel to another lifting channel 3. When the lifting vehicle descends to the bottom of the lifting channel 3, the outer toothed rings of the wheels on both sides of the lifting vehicle 5 mesh with the two fifth racks 91 and the two sixth racks respectively. The lower synchronous belt device 8 causes the lower shifting slide rail 9 and the lifting vehicle 5 to move from one lifting channel 3 to another lifting channel 4.

[0032] like Figure 1 and Figure 2 As shown, the lifting system also includes an inbound conveyor 20 located on one side of one of the lifting channels, an outbound conveyor 30 located on one side of the other lifting channel, and a rack 40 located on the other side of the two lifting channels. The rack is equipped with a traveling trolley 50 with forks for picking and placing goods. The inbound conveyor 20 and the outbound conveyor 30 can be synchronous belt conveyors. A front-of-warehouse chain conveyor 60 is also provided between the rack 40 and the two lifting channels. The front-of-warehouse chain conveyor 60 has multiple layers, each layer equipped with a chain conveyor 70, and each chain conveyor 70 corresponds to one layer of goods. The rack 40 includes several layers of goods, with the highest layer lower than the upper transfer rail 7. The inbound conveyor 20 and the outbound conveyor 30 each have only one layer. The overall principle of cargo loading and unloading is as follows: A lifting trolley 5 is moved to the same height as the inbound conveyor 20. After the inbound conveyor 20 moves the cargo box onto the lifting trolley 5, the lifting trolley moves to the predetermined location within two lifting channels. The front-of-warehouse chain conveyor 60 removes the cargo box from the lifting trolley 5, and then the forks of the traveling trolley 50 move the cargo box onto the traveling trolley 50. If the front-of-warehouse chain conveyor 60 is not installed, the forks of the traveling trolley 50 can also directly move the cargo box from the lifting trolley 5 to the traveling trolley 50. The outbound process is the reverse of the above. The cargo box on the shelf is moved by the traveling trolley 50 to the corresponding height position of the outbound conveyor 30 or the lifting trolley 5. The lifting trolley 5 moves to the position of the outbound conveyor 30, and the outbound conveyor 30 removes the cargo box.
