[0005] The transverse beam includes a pair of left and right lower transverse beams, and the running wheel is installed on the pair of left and right lower transverse beams.

[0006] The stand column comprises front and rear stand columns, the loading platforms are two front and rear loading platforms respectively installed on the front and rear stand columns, the front loading platform is located in front of the front stand column, and the rear loading platform is located in rear of the rear stand column; a drum conveyor rotating disc is installed on each loading platform;

[0007] The length of the longitudinal beam is limited to the single-row shelf type frame capable of walking in the aisle.

[0008] The multi-row shelf matched with the above-mentioned stacker is a three-dimensional grid shelf formed by a stand column, a transverse beam and a longitudinal beam, the three-dimensional grid is formed by a plurality of square frame matrices (six surfaces of which are matrices), the number of rows (Y-axis direction) in the three-dimensional matrix is N, N≥2, each square frame is a turnover box bin, a group of transmission drums of the drum conveyor is installed at the bottom of each turnover box bin, and a plurality of groups of transmission drums of each column and adjacent layer form a drum conveyor, and the axial direction of all the transmission drums of the turnover box bin is in the front and rear direction (parallel to the X-axis).

[0009] The single-row shelf type stacker is formed between two multi-row shelves, and the first row of shelves in each multi-row shelf is adjacent to the aisle, and the turnover box bins in each multi-row shelf are distributed in the form of a three-dimensional matrix.

[0010] The use method of the utility model will be illustrated below, in the example, two groups of adjacent transmission drums in the multi-row shelf form a drum conveyor, and the temporary storage bin of the above-mentioned stacker is distributed in six layers and two columns. In order to take out the turnover box in the third layer, the second column and the second row of turnover box bins of the multi-row shelf on the left side of the stacker, first, the stacker and the front loading platform thereof are moved to the front of the turnover box in the third layer, the second column and the first row of the multi-row shelf on the left side; second, the drum conveyor formed by the first and second groups of transmission drums in the third layer and the second column of the multi-row shelf on the left side is started to rotate in the positive direction, and the drum conveyor rotating disc of the front loading platform of the stacker and the drum conveyor of the third layer temporary storage bin are started to rotate in the positive direction, the turnover box in the first row of the third layer and the second column of the multi-row shelf on the left side (front box) and the turnover box in the second row (rear box) are sequentially moved out of the multi-layer shelf, enter the stacker through the front loading platform; third, when the front box enters the first column of the third layer temporary storage bin of the stacker and the rear box (the turnover box to be taken out) enters the front loading platform, the above-mentioned drum conveyor is closed; fourth, the front loading platform is lowered to the ground, the rear box (the turnover box to be taken out) is unloaded, and then the front loading platform is raised to the third layer; fifth, the above-mentioned drum conveyor is started to rotate in the reverse direction, the front box remaining in the first column of the third layer temporary storage bin of the stacker is sent back to the original position, i.e. the turnover box bin in the first row, the third layer and the second column of the multi-row shelf on the left side, and the above-mentioned drum conveyor is closed.

[0011] Compared with the prior art, the positive effect of this utility model is that multiple rows of shelves can be set on both sides of a single-row rack stacker crane. If there are five rows of shelves on each side, and an aisle is left for every two five-row shelves, the ratio of warehouse area occupied by the five rows of shelves to the aisle is 10:1. That is, this utility model significantly reduces the number of aisles and the area occupied, and correspondingly improves the utilization efficiency of the automated warehouse.

[0017] See Figure 1 The single-row rack stacker crane includes a frame, a loading platform 2, and wheels 1. The frame is a single-row rack 5, which consists of longitudinal beams 52, uprights 53, and transverse beams 54 forming multiple temporary storage compartments 6. All the storage compartments 6 are arranged in a matrix. In this embodiment, the matrix is ​​six layers and two columns. A set of drive rollers 3 of a roller conveyor is installed at the bottom of each storage compartment. Two sets of drive rollers of the same layer of storage compartments constitute a roller conveyor. The axial direction of all the drive rollers of the storage compartments is in the left-right direction (parallel to the Y-axis).

[0018] The transverse beam 54 includes a pair of left and right lower transverse beams, and the traveling wheel 1 has left and right traveling wheels. The traveling wheels on each side are installed on the lower transverse beam on the same side of the three-dimensional frame.

[0019] The loading platform consists of two loading platforms 2, one in front and one in back, which are respectively installed on the front and rear columns 53. The front loading platform is located in front of the front column and the rear loading platform is located behind the rear column. A roller conveyor rotary table 4 is installed on each loading platform.

[0020] The length of the longitudinal beam 52 is limited to the length of a single-row rack-type machine that can move through the aisle.

[0021] See Figure 2The multi-row racking system used in conjunction with the stacker crane is a three-dimensional mesh-type multi-layer racking system composed of longitudinal beams 52', uprights 53', and transverse beams 54'. The three-dimensional mesh consists of multiple square frames forming a six-layer, seven-column, or six-row three-dimensional matrix. Each square frame is a turnover box storage area, and a set of drive rollers 3 for the roller conveyor is installed at its bottom. Two adjacent sets of drive rollers in each column of the same layer constitute one roller conveyor. The axial direction of all the drive rollers in the turnover box storage area is in the front-to-back direction (parallel to the X-axis). Several adjacent sets can also be three adjacent sets, up to and including all drive rollers in the same layer, constituting one roller conveyor.

[0022] See Figure 3 and 4 The aforementioned stacker crane 200 is installed in the aisle 300 between two multi-row racks 100 on the left and right sides. Adjacent to the aisle is the first row of racks on each side, and the turnover boxes on each side are arranged in a three-dimensional matrix. The following example illustrates the usage of this utility model. To retrieve the stacker crane... Figure 3 The first step is to move the stacker crane 200 and its front loading platform 2 to the third layer, second column, and first row of turnover boxes d on the left-side multi-row racks. The second step is to start the roller conveyor consisting of the first and second groups (consistent with the row number) of drive rollers 3 on the second column and third layer of the left-side multi-row racks in a forward rotation. At the same time, the roller conveyor rotary disk 2 of the stacker crane's front loading platform and the roller conveyor of the third-layer temporary storage bin are started in a forward rotation. The turnover boxes d (front boxes) and c (rear boxes) in the second column, third layer, and first row of the left-side multi-row racks are moved out of the multi-row racks in sequence, pass through the front loading platform, and enter the stacker crane. The third step is to shut down the roller conveyor when the front box enters the first column of the third layer of the stacker crane's temporary storage bin and the rear box (the turnover box to be retrieved) enters the front loading platform. The fourth step is to lower the front loading platform to the ground (see...). Figure 2 After unloading the rear box and retrieving the turnover box, it is raised to the third layer; the fifth step is to start the above roller conveyor to reverse, and the front box that is stuck on the first row of the temporary storage warehouse on the third layer of the stacker crane is sent back to its original position via the front loading platform—the turnover box warehouse of the first row, third layer and second column of the multi-row rack on the left, and the above roller conveyor is shut down.
