Description

Balancing method of transport distance and water level of aerial storage device based on multi-overhead crane track Technical Field

[0001] The utility model relates to the field of automatic handling systems, in particular to a balancing method for the handling distance and water level of an aerial storage device based on a multi-overhead crane track. Background Art

[0002] Overhead crane handling systems are a crucial automated handling system in smart factories. They significantly improve the overall production process by increasing material transport efficiency, reducing labor costs, and minimizing pollution risks. As the storage device for the overhead crane handling system, aerial storage devices play a crucial role. The material control system receives carrier handling requests from different systems and places them into the aerial storage devices. When there are multiple aerial storage devices, the storage location of the carriers, the number of carriers stored in each aerial storage device, and the distance the overhead cranes must travel directly impact the factory's material transport efficiency. Under existing technology, the material control system receives carrier handling requests from different systems and randomly places the carriers into the aerial storage devices with available storage space. This fails to fully consider the distance the materials in the carriers must travel to the production process and the storage balance within the aerial storage devices, resulting in low material transport efficiency in the factory.

BRIEF DESCRIPTION OF THE DRAWINGS

[0018] FIG1 is a schematic diagram of a path configuration in a method for balancing the transport distance and water level of a multi-overhead crane track aerial storage device according to the present invention. DETAILED DESCRIPTION

[0019] The technical solution of the present invention is further described below in conjunction with specific embodiments:

[0020] A method for balancing the transport distance and water level of a multi-overhead crane track aerial storage device includes the following steps:

[0021] Step 1: Configure path weights. Specifically, as shown in Figure 1, according to the Dijkstra algorithm, the distance weight of each location point from the next reachable adjacent point is sequentially configured. If not configured, the weight is infinite. In the figure, OHT is the overhead crane handling system, OHB is the overhead crane storage device, and EQP is the equipment.

[0023] PB point configuration (with direction)

[0024] PC point configuration (with direction)

[0025] ...

[0026] PM point configuration (with direction)

[0027] ...

[0028] PP point configuration (with direction)

[0029] Step 2: The carriers transporting the materials are stored in the aerial storage device. The corresponding aerial storage device water level weight is configured according to the quantity of materials in the carrier and the importance of the materials;

[0030] In this embodiment, as shown in Table 1 below

[0031] Table 1

[0032] Step 3: Configure the calculation weight ratios, as shown in Table 2 below, for the weight ratios of path distance weight, material weight, and percentage of used air storage device slots.

[0033] Table 2

[0034] Step 4: Calculate the overall weight. Assign the route distance weight percentage to x, the material weight percentage to y, and the percentage of used overhead storage slots to z. The overall weight is calculated as: Overall Weight = Route Distance Weight × x + Material Weight × y + Used Overhead Storage Slots % × z. Materials are prioritized based on the overall weight. The lower the overall weight, the higher the corresponding material handling priority, meaning that materials with lower overall weights are prioritized.
