The first restraint body 124 and the second restraint body 125 may be located between one end of the first slideway 12i and one end of the third slideway 12k such that the first slideway 12i and the third slideway 12k are separated by the first restraint body 124 and the second restraint body 125. Under the restriction of the first stopper body 124 and the second stopper body 125, the bin 4 can enter and exit the first chute 12i only via the other end of the first chute 12i, and can enter and exit the third chute 12k only via the other end of the third chute 12k. The bin 4 entering the first chute 12i and the third chute 12k is slidable along the first chute 12i and the third chute 12k under the guidance of the first guide portion 12a and the second guide portion 12 d. At the same time, the magazine 4 may abut the first support 12b and the third support 12e, so that the first support 12b and the third support 12e can jointly support the magazine 4.

The first beam 121 and the third beam 123 may define a second slideway 12j and a fourth slideway 12m, and the spacing between the first beam 121 and the third beam 123 may be adapted to the width of the magazine 4. One end of the second slideway 12j and one end of the fourth slideway 12m may be arranged opposite to each other, and the other end of the second slideway 12j and the other end of the fourth slideway 12m may be arranged away from each other. The third stop body 126 and the fourth stop body 127 may be located between one end of the second slideway 12j and one end of the fourth slideway 12m, such that the second slideway 12j and the fourth slideway 12m are separated by the third stop body 126 and the fourth stop body 127. Under the restriction of the third stopper body 126 and the fourth stopper body 127, the magazine 4 can enter and exit the second chute 12j only via the other end of the second chute 12j, and can enter and exit the fourth chute 12m only via the other end of the fourth chute 12m. The bins 4 that enter the second chute 12j and the fourth chute 12m can slide along the second chute 12j and the fourth chute 12m under the guidance of the first guide portion 12a and the third guide portion 12 f. At the same time, the magazine 4 may abut against the second and fourth support portions 12c, 12g, such that the second and fourth support portions 12c, 12g are able to jointly support the magazine 4.

Further, in the case where a plurality of cross beams are arranged side by side, the cross beam having an L-shaped cross section may be the first cross beam or the last cross beam in a row of cross beams. For example, in the present embodiment, the first beam 122 and the third beam 123 may have the same structure, and a plurality of first beams 121 or a plurality of third beams 123 may be located between two second beams 122.

In this way, by making the first runner 12i and the second runner 12j share the first cross member 121, the first runner 12i and the second runner 12j can have a smaller interval therebetween, so that the rack 1 can have a higher storage density. Given the same total volume of the stored magazines 4, the pallet 1 can have a smaller volume, so that the pallet 1 can have a lower material cost. Further, by providing a support portion on the cross beam, the cross beam can support the tank 4 while guiding the tank 4 to slide. The goods shelf 1 does not need to be additionally provided with a component for supporting the material box 4, so that the material box 4 can be stored more compactly in the vertical direction, thereby further improving the storage density and reducing the material cost of the goods shelf 1.

By forming the cross section of the cross beam into a T shape or an L shape, the guide portion can function as a reinforcing rib of the cross beam while playing a role of guiding, so that the cross beam can have high strength, and the shelf 1 has high load bearing capacity. Furthermore, by providing a third slide 12k, which is facing away from the first slide 12i, the magazine 4 can enter and leave the rack 1 from two opposite directions. In case the length of the cross beam is larger than the maximum length of the first telescopic mechanism 21 (see below), the first handling device 2 can still easily access the bin 4, so that the cross beam can have a longer length, thereby enabling to improve the storage capacity of the single shelf 1. Further, by separating the first chute 12i and the third chute 12k, the bin 4 in the first chute 12i and the bin 4 in the third chute 12k do not collide with each other during sliding, so that the bin 4 in the first chute 12i is not ejected by the bin 4 in the third chute 12k, and the bin 4 in the third chute 12k is not ejected by the bin 4 in the first chute 12i, thereby avoiding the risk of the bin 4 falling.

The length of the mounting portion 13c may be adapted to the length of the magazine 4, and the width of the mounting portion 13c may be smaller than the width of the magazine 4. The mounting portion 13c may be horizontally fixed to the bridge 115, and the plurality of buffer shelves 131 may be arranged in two rows. Two rows of cache shelves 131 may be coupled to each other

In a spaced apart relationship, the channel 13a may be located between two columns of buffer shelves 131 and extend through the entire shelf 1. A corresponding buffer position can be defined below each buffer 0 shelf 131, and each buffer position can be provided with a two-dimensional code 13b for distinguishing the buffer shelf 131.

The guide frames 132 may be fixed to the bridge 115, and each two guide frames 132 may correspond to one buffer frame 131. The two guide frames 132 may be spaced apart from each other in the width direction of the placement portion 13c, and the interval between the two guide frames 132 may be adapted to the width of the magazine 4.

Specifically, when the bin 4 needs to be stored on the shelf 1, the bin 4 may be sucked by the suction cups, and the first vehicle body 24 may transport the bin 4 to a target position beside the shelf 1. After the first vehicle body 24 reaches the target position, the slider 23 may be moved along the guide rail 22 so that the bin 4 is lifted to a height corresponding to the storage level 11 a. Then, as shown in fig. 4, the first telescoping mechanism 21 can be extended, and the bin 4 can enter the chute by the driving of the first telescoping mechanism 21.

Given the same total volume of the bins 4 stored, the rack 1 can have a smaller volume, so that the rack 1 can have a lower material cost. Further, by providing a support portion on the cross beam, the cross beam can support the hopper 4 while guiding the hopper 4 to slide. The goods shelf 1 does not need to be additionally provided with a component for supporting the material box 4, so that the material box 4 can be stored more compactly in the vertical direction, thereby further improving the storage density and reducing the material cost of the goods shelf 1.

(iii) By providing a third slide 12k, facing away from the first slide 12i, the magazine 4 can enter and leave the rack 1 from two opposite directions. In the case that the length of the cross beam is greater than the maximum length of the first telescopic mechanism 21, the first carrying device 2 can still easily access the bin 4, so that the cross beam can have a longer length, and the storage capacity of a single rack 1 can be improved.

(iv) By separating the first chute 12i and the third chute 12k, the bin 4 in the first chute 12i and the bin 4 in the third chute 12k do not collide with each other during sliding, so that the bin 4 in the first chute 12i is not ejected by the bin 4 in the third chute 12k, nor is the bin 4 in the third chute 12k ejected by the bin 4 in the first chute 12i, thereby avoiding the risk of the bin 4 falling.
