Description

TECHNICAL FIELD

[0001] The utility model relates to the stacking machine and goods shelves used in stereoscopic warehouse. BACKGROUND

[0002] The application is applied to the aisle (also called passageway) between two goods shelves of stereoscopic warehouse, and the aisle type stacking machine comprises a rack, a loading platform and traveling wheels. The double-column rack is composed of front and rear columns and upper and lower cross beams to form a rectangular frame, also called a plane rack. The loading platform is installed on the front column or the rear column and located in the rectangular frame, i.e. between the front and rear columns, and moves up and down on the column for loading and lifting. The traveling wheels are installed on the lower cross beam of the rack and travel on the ground rail. The equipment of the stereoscopic warehouse further comprises a handling tool such as an automatic guided vehicle or a drum conveyor for handling the turnover boxes between the goods shelves and the loading platform of the stacking machine (see "Automatic Stereoscopic Warehouse - A Complete Guide" published by China Material Press in November 2010). Each side of the aisle type stacking machine (hereinafter referred to as left and right) is a single-row goods shelf. The single-row goods shelf is composed of columns, transverse beams and longitudinal beams to form multiple turnover box warehouses (for storing turnover boxes). Each turnover box warehouse is a square frame, and the positions of all the turnover box warehouses are arranged in a matrix, i.e. multiple layers in height (on the Z axis), multiple columns in front and back (in the direction of the stacking machine, also on the X axis), and a row in left and right (on the Y axis). Each turnover box directly falls on the turnover box warehouse or a group of goods shelf brackets (hereinafter referred to as brackets). The aisle type stacking machine requires that a passageway be provided between every two (single-row) goods shelves. In this way, one third of the effective area of the warehouse is occupied by the passageway, and the goods shelves only occupy the remaining two-thirds of the area, i.e. the area occupied by the goods shelves and the passageway is in a ratio of 2:1, which obviously reduces the use efficiency of the stereoscopic warehouse. SUMMARY

[0003] In order to improve the use efficiency of the stereoscopic warehouse, the utility model aims to provide a single-row stacking machine and a multi-row goods shelf for automatic guided vehicle handling.

[0004] The single-row goods shelf type stacking machine for automatic guided vehicle handling comprises a rack, a loading platform and traveling wheels, and is characterized in that: the rack is a single-row goods shelf composed of longitudinal beams, columns and transverse beams to form multiple turnover box warehouses (hereinafter referred to as temporary storage warehouses) for temporarily storing turnover boxes, and the positions of all the temporary storage warehouses are arranged in a matrix.

[0005] The transverse beam comprises a pair of left and right lower transverse beams, and the traveling wheels are installed on the pair of left and right lower transverse beams.

[0006] The loading platform is two loading platforms, which are respectively installed on the front and rear columns, namely, the front loading platform is located in front of the front column, and the rear loading platform is located behind the rear column.

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

[0008] The multi-row rack matched with the above-mentioned stacker is a three-dimensional grid rack composed of columns, transverse beams and longitudinal beams, the three-dimensional grid is a three-dimensional matrix composed of a plurality of square frames (all six surfaces 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 floor and a bracket are arranged in each turnover box bin from bottom to top, and the spacing of the floor and the bracket is limited to that when the turnover box falls into the bracket, the automated guided vehicle can work in the gap between the floor and the bottom of the turnover box.

[0009] The single-row rack type stacker forms an aisle between two multi-row racks, and the first row of racks on each side of the multi-row racks is adjacent to the aisle, and the turnover box bins of each side of the multi-row racks are distributed in a three-dimensional matrix.

[0010] The use method of the utility model will be described below by taking the six-layer and two-column distribution of the temporary storage bin of the above-mentioned stacker as an example. To take out the turnover box in the third layer, the third column and the second row of turnover box bins on the left side of the multi-row rack of the stacker, first, the stacker and the front loading platform thereof move to the front of the turnover box in the third layer, the third column and the first row of the left side of the multi-row rack; second, the automated guided vehicle carries the turnover box in the third layer, the third column and the first row (front box) to the third layer and the first column of the temporary storage bin and the bracket thereof of the stacker through the front loading platform, that is, the front box in front of the turnover box to be taken out is removed first; third, the automated guided vehicle carries the turnover box to be taken out (rear box) to the front loading platform of the stacker; fourth, the front loading platform is lowered to the ground, the rear box is unloaded, and then the front loading platform is raised to the third layer; fifth, the automated guided vehicle carries the front box on the temporary storage bin to the original position, that is, the bracket in the third layer, the third column and the first row through the front loading platform. When the turnover box in the third layer, the third column and the third row is taken out, the second step and the fifth step are repeated, and so on.

[0011] Compared with the prior art, the utility model has the positive effect that the multi-row racks can be arranged on both sides of the single-row rack type stacker. If there are five rows of racks on each side, when one aisle is left between every two five-row racks, the ratio of the area occupied by the five-row racks and the aisle is 10:1, that is, the utility model significantly reduces the number and area of the aisle, and correspondingly improves the use efficiency of the three-dimensional warehouse.
