[0029] The utility model will be further explained in detail below according to the drawings and implementation cases.

[0030] In the present specification, the orientation terms such as up, down, left, right, front, back, front, back, top, bottom, etc. mentioned or possibly mentioned are defined relative to the structure shown in the drawings, and the words "inner" and "outer" respectively refer to the direction towards or away from the geometric center of a particular component. They are relative concepts, so they may change accordingly according to their different positions and different use states. Therefore, these or other orientation terms should not be interpreted as restrictive terms.

[0031] Example 1:

[0032] A material taking device, referring to Figures 1-5 , comprising a rack 1, a lifting mechanism 2 slidingly arranged on the rack 1 in the vertical direction, a material taking mechanism 3 slidingly arranged on the rack 1 in the vertical direction, a first lifting mechanism 4 and a second lifting mechanism (not shown in the figure), the lifting mechanism 2 has a first supporting assembly 22 which can move repeatedly in the first direction and is used for supporting the material box m, the material taking mechanism 3 is located below the lifting mechanism, the material taking mechanism 3 has a second supporting assembly which can move repeatedly in the first direction and is used for supporting the material box m, the first lifting mechanism 4 is used to drive the lifting mechanism 2 to move vertically or lock, and the second lifting mechanism is used to drive the material taking mechanism 3 to move vertically or lock.

[0033] In addition, multiple material boxes m are placed in the vertical direction, and a gap m1 for the first supporting assembly 22 and the second supporting assembly to pass through is formed between any adjacent two material boxes m stacked in the vertical direction, the gap m1 is arranged in extension in the first direction, and the moving stroke of the first supporting assembly 22 and the second supporting assembly in the vertical direction covers any one material box m.

[0034] The taking process is as follows: when the Nth layer of bins m is taken (note: the Nth layer of bins m does not include the bin m at the lowermost layer and the bin m at the uppermost layer), the first lifting mechanism 4 drives the lifting mechanism 2 to move vertically so that the first supporting assembly 22 moves to the height of the gap m1 between the Nth and N+1th layers, and moves along the first direction by using the first supporting assembly 22 to insert into the gap m1 between the Nth and N+1th layers, and then the first lifting mechanism 4 drives the lifting mechanism 2 to move upwards, so that all the bins m above the Nth layer are lifted and separated from the Nth layer of bins. Then, the second lifting mechanism drives the taking mechanism 3 to move vertically so that the second supporting assembly moves to the gap m1 between the Nth and N-1th layers, and moves along the first direction by using the second supporting assembly to extend and insert into the corresponding gap m1, and then the second lifting mechanism drives the second supporting assembly to slightly rise so that the second supporting assembly can lift the Nth layer of bins m, and controls the second supporting assembly to retract along the first direction and descend. Finally, the first supporting assembly 22 is controlled to fall and place the lifted bins m on the N-1th layer of bins m, and the first supporting assembly 22 is controlled to retract, that is, the taking is completed.

[0035] In the embodiment, the first lifting mechanism 4 controls the lifting mechanism 2 to temporarily lift the bins m above the target layer, and the taking mechanism 3 separately extracts the bins m of the target layer, which realizes accurate positioning of the target bins m, reduces the interference of the bins above the target layer on the extraction of the target layer of bins m, and helps to improve the taking efficiency. Moreover, controlling the lifting mechanism 2 to descend can realize effective placement of the lifted bins m, which helps to improve the overall taking efficiency.

[0036] Meanwhile, the stacked bins m help to improve the utilization rate of vertical space and can effectively save costs.

[0037] It should be noted that the number of stacked bins m is ≤5, so as to avoid the first supporting assembly 22 from being broken due to too large weight.

[0038] In addition, it should be noted that the moving stroke of the first supporting assembly 22 and the second supporting assembly in the vertical direction covers any one bin m, which means that when the first supporting assembly and the second supporting assembly can move in the vertical direction, they can cover any one bin, that is, the lowest point that the first supporting assembly can move to should be below the bin m at the lowermost layer, and the highest point that the first supporting assembly can move to should be above the bin m at the uppermost layer, so as to extract the bin m at any height.

[0039] In the embodiment, in order to facilitate the manufacture of the device, the lifting mechanism 2 and the material taking mechanism 3 are arranged in the same structure, specifically, the lifting mechanism 2 comprises a mounting plate 21, a first supporting assembly 22 slidingly arranged on the mounting plate 21 in a first direction, and a driving assembly 23 for driving the first supporting assembly 22 to move in the first direction, and the mounting plate 21 is slidingly connected to the rack 1 in a vertical direction.

[0040] It should be noted that a sliding groove extending in the first direction can be arranged on the mounting plate 21, and the first supporting assembly 22 is slidingly arranged in the sliding groove, so as to realize stable sliding of the first supporting assembly 22 on the mounting plate 21.

Figure 4 The two gaps m1 are formed at the two side edges of the material box m, and when the supporting plates 222 are needed to support the material box m, the two supporting plates 222 are inserted into the other two gaps m1 respectively. The vertical extension of the limiting plates 221 can limit the material box m in the vertical direction, which helps to improve the position stability of the material box m. In addition, it should be noted that the supporting plates 222 need to have a certain width to ensure that the two supporting plates 222 have a certain contact area with the bottom of the material box m, so as to stably support the material box m.

[0042] In the embodiment, a connecting plate 24 is arranged between the two limiting plates 221, and the connecting plate 24 is located at the side of the limiting plate 221 away from the material box m, in this structure, the two limiting plates 221 form a whole, which helps to improve the structural stability of the first supporting assembly 22.

[0043] In the embodiment, the driving assembly 23 can be arranged as a pneumatic cylinder or an oil cylinder, and is mounted on the mounting plate 21, and the telescopic end of the driving assembly 23 is connected to the connecting plate 24, and when working, the movement of the telescopic end of the driving assembly 23 can drive the two supporting plates 222 to move repeatedly in the first direction.

The lifting motor 41 in the second lifting mechanism is installed on the bottom of the rack 1. In operation, the lifting motor 41 in the first lifting mechanism 4 drives the screw rod 42 to rotate, thereby driving the mounting plate 21 connected with the screw rod 42 to vertically ascend relative to the rack 1, so as to realize the lifting control of the lifting mechanism 2, and the control of the second lifting mechanism on the material taking mechanism 3 is the same.

[0045] In the embodiment, the rack 1 is provided with at least one guide rail extending in the vertical direction, and the lifting mechanism 2 and the material taking mechanism 3 are provided with at least one sliding member corresponding to each guide rail, the sliding member is slidingly connected with the corresponding guide rail, and the sliding cooperation of the sliding rail and the sliding member can ensure the stable sliding of the lifting mechanism 2 and the material taking mechanism 3 on the rack 1.
