Problems solved by technology

This method concentrates the same batch of meters in a certain roadway, causing the stacker to be busy and the task to be completed slowly;
[0005] (2) Unreasonable allocation of storage slots
This method does not consider the running speed of the stacker, and it is prone to the phenomenon that the vertical or horizontal running time is too long, resulting in slow loading and unloading;
[0007] (3) Unreasonable assignment of tasks
[0008] The current storage strategy can only issue tasks one by one when performing new table storage, verification output, and verification storage tasks, and cannot make full use of the double-fork stacker; when there are multiple tasks waiting to be executed, the execution time cannot be selected The shortest task is issued, causing the stacker to run repeatedly and inefficient

Embodiment Construction

[0040] The embodiments of the present invention will be described in further detail below.

[0041] (1) Alleyway distribution: Before distributing the goods to the roadways, count the number of such goods stored in each roadway, and give priority to the distribution in the roadways with fewer goods. The same batch of goods should be allocated to each roadway as much as possible to avoid entering and leaving. The library is crowded. The specific distribution quantity determines the quantity of goods distributed to each lane according to formula (1):

[0042] (1)

[0043] Where: The quantity of goods should be allocated for the i-th lane;

[0044] M is the total reserves of the roadway;

[0045] Is the existing reserves in the roadway;

[0046] j=1,2,3...n;

[0047] n is the total number of lanes.

[0048] In this step, 100 cargoes are used as a benchmark to average the reserves of each roadway. In this embodiment, each roadway has a total of 2704 storage locations, and the occupancy ...

Abstract

The invention relates to a storage distribution method for a stereoscopic storehouse. The storage distribution method for the stereoscopic storehouse comprises the following steps of (1) roadway distribution, specifically, the quantity of goods stored in all roadways is calculated, the quantity of goods to be distributed to the roadways is determined according to a formula (please see the specification for the formula), in the formula, m'i refers to the quantity of goods to be distributed to the i roadway, M refers to the total storage quantity of the roadway, and mi refers to the current storage quality of the roadway; and (2) storage space distribution, specifically, the position parameter omega is set according to a formula (please see the specification for the formula), omega is set between 0.7 and 1, and the coordinates (X, Y) of a target storage space are obtained; in the formula, omega is the position parameter, vx refers to the horizontal operating speed of a stacking machine, and vy refers to the vertical operating speed of a goods table, X refers to the line where the goods table is located, and Y refers to the layer where the goods table is located. According to the storage distribution method for the stereoscopic storehouse, roadway distribution is optimized, the storage spaces are distributed according to the principle that time for goods to enter and come out of the storehouse is the shortest, and a task issuing method is optimized according to the principle that the total execution time of the double-fork stacking machine of the stereoscopic storehouse is the shortest.

Description

Technical field [0001] The invention relates to a storage distribution method of a warehouse, in particular to a storage distribution method of a three-dimensional warehouse. Background technique [0002] The three-dimensional warehouse has a total of 8 stackers, 16 rows of shelves, 1,320 pallet storage positions, and 16,094 turnover box storage positions. It can store more than 1.3 million various metering devices and has a daily throughput of more than 100,000. In view of the huge storage capacity of the warehouse and heavy daily tasks, reasonable selection of storage locations and reasonable dispatch of tasks can enable the stacker to quickly complete the tasks. However, the current storage strategy is relatively simple, mainly reflected in: [0003] (1) Unreasonable allocation of roadways [0004] The current storage strategy only compares the reserves of each roadway, selects the roadway with the smallest reserve, and distributes goods to the roadway until the average value is...
