The technical solutions of the embodiments of the present application are described in detail below with reference to the accompanying drawings.
Referring to fig. 1 and 2, the warehousing system of the present embodiment includes a plurality of shelf units 100 and a warehousing robot 200.
The shelf units 100 are distributed at intervals, the partition areas between adjacent shelf units 100 form a roadway 102, the shelf units 100 comprise two upright column groups 120 and 130 arranged at two ends of the roadway 102 in the width direction, the upright column groups 120 and 130 comprise a plurality of upright columns distributed at intervals in the length direction of the roadway 102, the upright columns are connected into a whole through cross beams 146 extending in the length direction, a storage column 104 is formed between the adjacent upright columns, and the storage column 104 is provided with a plurality of storage layers 106; at least part of the two opposite upright post groups 120 and 130 of the adjacent shelf units 100 close to one end of the roadway 102 are provided with climbing chains 110;
the warehousing robot 200 has a movable base for driving the warehousing robot to move on a support surface, a handling device and a climbing assembly for ascending and descending along a plurality of climbing chains 110 so as to transfer the storage object between the handling device and the target storage tier 106, i.e. so that the handling device acquires the storage object from the target storage tier 106 or places the storage object on the target storage tier 106;
wherein the height of the warehousing robot 200 is less than the height of the cross beam 146 at the bottom of the shelf unit 100.
In some embodiments, the plurality of columns of each column set 120, 130 are integrally connected by a top cross-member 145 and a bottom cross-member 146.
In the embodiment of the present application, the height of the warehousing robot 200 is set to be less than the height of the cross beam 146 at the bottom end of the shelf unit 100, so that the warehousing robot 200 can walk at the bottom of the shelf unit instead of walking along a roadway, thereby reducing the walking distance and rapidly reaching the target position.
In one related art, the movement of the warehousing robot is limited by the height of the lowest tier of the shelving unit, and cannot pass through the bottom of the shelving unit 100, but only along the length of the roadway 102 or around the shelving unit 100, as shown in fig. 23. Suppose that the workstation which needs to get goods from the point A to the point B and then arrives at the point C needs to walk to the bottom of the roadway according to the illustrated route and then go to the workstation.
Referring to fig. 24, according to the embodiment of the present application, the warehousing robot can walk on the bottom of the shelf unit, and thus can have a higher degree of freedom, for example, can walk in a checkerboard type walking manner. Assuming that the warehousing robot has the same starting point, ending point and pick-up point as those shown in fig. 23, i.e. a workstation which needs to pick up goods from point D to point E and then arrives at point F, the warehouse robot can travel from point D along the lane 102 to the position aligned with point E, then traverse from the bottom of the shelving unit 100 to the point E across the shelving unit 100 and the lane 102 to pick up goods, and then continue to traverse across the shelving unit 100 and the lane 102 to the workstation which arrives at point F. In the present application, the checkerboard type walking manner means that the warehousing robot can walk in an imaginary checkerboard type walking space according to a determined walking path, and the walking path is defined by the edges of the checkerboard to be passed through. It will be appreciated that the specific checkerboard and edges that are traversed may depend, for example, on system scheduling, need to avoid obstacles, etc. The position and size of the grid in the checkerboard may depend, for example, but not limited to, the position of the columns of shelving units, the width of the columns, the shelving units, the spacing between adjacent shelving units, etc.
As can be known by comparing the walking routes shown in the figures 23 and 24, the warehousing robot in the embodiment of the application can achieve the function of taking and placing goods in a cross-roadway mode in the goods shelf area, the running route from a workstation to the warehouse area is high in selectivity, congestion is reduced, the number of rotation times is reduced in the whole running process, the walking route is saved, and the single-car efficiency of the robot is improved. In addition, due to the fact that the walking space is larger, the number of the warehousing robots in the site can be increased while the possibility of congestion is not increased.
Referring to fig. 3, in some embodiments, the multiple columns of the column sets 120 and 130 include a floor column 112 and a floating column 114, where the floor columns 112 and the floating columns 114 are alternately arranged, that is, one floating column 114 is disposed between adjacent floor columns 112. Storage columns 104 are formed between adjacent ground and flying pillars 112, 114. It is understood that in other embodiments, two or more suspension posts 114 may be disposed between adjacent ground posts 112, a storage column 104 is formed between adjacent ground posts 112 and suspension posts 114, and a storage column 104 is also formed between adjacent suspension posts 114. It will be appreciated that the spacing between adjacent posts may be the same or different. In this embodiment, set up unsettled stand between the stand 112 that falls to the ground, and form the storage between adjacent stand 112 that falls to the ground and unsettled stand 114 and be listed as, with only falling to the ground stand and forming the storage of equal width between the stand and be listed as and compare, the interval between the stand that falls to the ground is bigger for storage robot has bigger degree of freedom when walking to goods shelf unit below from the tunnel, reduces storage robot walking control degree of difficulty.
In some embodiments, the climbing chain 110 is mounted on the corresponding vertical column through a plurality of fixing seats 142, and the plurality of fixing seats 142 are distributed at predetermined positions at two vertical ends and between the two vertical ends of the climbing chain 110, for example, in the example of fig. 3, the climbing chain 110 is mounted on the corresponding vertical column through two fixing seats 142 distributed at two vertical ends and two fixing seats 142 in the middle. It will be appreciated that the spacing between adjacent mounts 142 may be the same or different. In the related art, the climbing chain is only fixed to the vertical column at the upper end and the lower end, and the problem that the length deviation of the chain is large due to too many chain sections, so that the height of the shelf unit is limited exists. In this embodiment, the climbing chain 110 is directly mounted to the column by the plurality of fixing bases distributed at the preset positions between the two vertical ends and the two ends of the climbing chain 110, so that the accuracy of the length of the chain between the adjacent fixing bases can be ensured, thereby reducing the deviation of the overall length of the chain and allowing the shelf unit to have a higher height.
