Description

Technical Field

[0001] This utility model relates to aisle stacker cranes and racks used in automated warehouses. Background Technology

[0002] Aisle stacker cranes, used in the aisles (also called passageways) between two racks in automated warehouses, include a frame, a loading platform, and wheels. A double-column frame consists of two uprights (front and rear) and two crossbeams (upper and lower), forming a rectangular frame, also known as a flat frame. The loading platform is installed on the front or rear upright, located within the rectangular frame between the uprights, and moves up and down on the uprights for lifting and lowering goods. Wheels are wheels installed on the lower crossbeams of the frame and travel on ground rails. Automated warehouse equipment also includes handling equipment such as automated guided vehicles (AGVs) or roller conveyors, used to move containers between the racks and the stacker crane's loading platform (see *Automated Warehouse Management Guide*, published by China Materials Publishing House, November 2010). Aisle-type stacker cranes have a single-row rack on each side. Each row consists of multiple storage compartments (for storing containers) formed by uprights, transverse beams, and longitudinal beams. Each compartment has a grid-like frame, and all compartments are arranged in a matrix, meaning multiple layers in height (Z-axis), multiple rows in front-to-back (X-axis, referring to the stacker crane's travel direction), and a single row in the left-to-right (Y-axis) directions. Aisle-type stacker cranes require an aisle between every two (single-row) racks. This results in aisles occupying one-third of the warehouse's effective area, leaving only two-thirds occupied by racks (a 2:1 ratio), which significantly reduces the efficiency of the automated warehouse. Summary of the Invention

[0003] In order to improve the utilization efficiency of automated warehouses, the purpose of this utility model is to provide a single-row rack stacker and a multi-row rack for roller conveyor handling.

[0004] A single-row rack-type stacker crane for handling by roller conveyors includes a frame, a loading platform, and wheels. Its features include: the frame is a single-row rack, consisting of longitudinal beams, columns, and transverse beams forming multiple temporary storage compartments (hereinafter referred to as temporary storage compartments). All temporary storage compartments are arranged in a matrix, including multiple layers. A set of drive rollers for a roller conveyor is installed at the bottom of each temporary storage compartment. All drive rollers in the same layer of temporary storage compartments constitute a single roller conveyor (using a single drive mechanism). The axial direction of all drive rollers in the temporary storage compartments is in the left-right direction (parallel to the Y-axis).

[0005] The transverse beams include a pair of left and right lower transverse beams, and the traveling wheels are mounted on the pair of left and right lower transverse beams;

[0006] The column includes a front column and a rear column. The loading platform consists of two loading platforms, one in front and one in back, which are respectively installed on the front column and the other in back column. 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 turntable is installed on each loading platform.

[0007] The length of the longitudinal beams is limited to the length of a single-row rack that allows movement in the aisle.

[0008] The multi-row racks transported by the roller conveyor used in conjunction with the stacker crane are three-dimensional grid racks composed of columns, transverse beams and longitudinal beams. The three-dimensional grid is a three-dimensional matrix composed of multiple square frames (all six sides of which are matrix). The number of rows (in the Y-axis direction) in the three-dimensional matrix is ​​N, N≥2. Each square frame is a turnover box warehouse, and a set of drive rollers of the roller conveyor is installed at its bottom. Several adjacent sets of drive rollers in each row of the same layer constitute a roller conveyor. The axial direction of all the drive rollers of the turnover box warehouses is in the front-back direction (parallel to the X-axis).

[0009] A single-row rack stacker crane operation aisle is formed between two multi-row racks. The first row of racks on each side is adjacent to the aisle. The turnover box warehouses on each side are distributed in a three-dimensional matrix.

[0010] The following example illustrates the usage of this utility model. In this example, two adjacent sets of drive rollers in the multi-row racks constitute a roller conveyor. The aforementioned stacker crane's temporary storage compartments are arranged in six layers and two columns. To retrieve the turnover boxes from the third layer, third column, and second row of the turnover box compartments on the left side of the multi-row racks, the first step is that the stacker crane and its front loading platform move to the front of the turnover boxes in the third layer, third column, and first row of the left side multi-row racks. The second step is to start the roller conveyor consisting of the first and second sets of drive rollers in the third column and third layer of the left side multi-row racks to rotate forward. Simultaneously, the roller conveyor turntable of the stacker crane's front loading platform and the roller conveyor of the third-layer temporary storage compartment are started to rotate forward, and the turnover boxes in the third column, third layer, and first row (front boxes) and the second row (rear boxes) of the left side multi-row racks are rotated forward. The first step involves moving the boxes out of the multi-layer racks and into the stacker crane via the front loading platform. The second step is to shut down the roller conveyor when the front box enters the first row of the third layer of the stacker crane's temporary storage compartment and the rear box (the one to be retrieved) enters the front loading platform. The third step is to lower the front loading platform to the ground, unload the rear box (the one to be retrieved), and then raise it to the third layer. The fourth step is to start the roller conveyor to reverse, and the front box remaining in the first row of the third layer of the stacker crane's temporary storage compartment is sent back to its original position via the front loading platform—the turnover box compartment in the first row, third layer, and third column of the multi-layer racks on the left. The roller conveyor is then shut down.

[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.
