Abstract

The disclosure provides a material handling method and system. The method includes: obtaining a carrying load of at least two carrying devices on a current production line in a present working period; adjusting a carrying area of at least two carrying devices according to the carrying load, and/or, adjusting the carrying priority level of the sharing carrying sub-area and the independent carrying sub-area of at least two carrying devices according to the carrying load. Each carrying area of one carrying device comprises a sharing carrying sub-area and an independent carrying sub-area.

First claim

What is claimed is:

1. A material handling method comprising:
obtaining carrying loads of a first carrying device and a second carrying device respectively on a current production line in a current working period, wherein the first and second carrying devices are responsible for carrying materials needed in a production process, and the carrying loads are amounts of materials which are required to be carried by the first and second carrying device;
adjusting carrying areas corresponding to the first and second carrying devices according to the carrying loads, wherein the carrying area of the first carrying device comprises a sharing carrying sub-area and a first independent carrying sub-area, the carrying area of the second carrying device comprises the sharing carrying sub-area and a second independent carrying sub-area, the first independent carrying sub-area is used for the first carrying device independently carrying the material therein, the second independent carrying sub-area is used for the second carrying device independently carrying the material therein, and the sharing carrying sub-area is used for both the first and second carrying devices carrying the material therein; and
adjusting carrying priority levels of the sharing carrying sub-area and the first and second independent carrying sub-areas of the first and second carrying devices according to the carrying loads, comprising:
for the first carrying device with a larger carrying load, adjusting the carrying priority level of the first independent carrying sub-area to be greater than the carrying priority level of the sharing carrying sub-area;
for the second carrying device with a smaller carrying load, adjusting the carrying priority level of the sharing carrying sub-area to be greater than the carrying priority level of the second independent carrying sub-area.

2. The method as claimed in claim 1 , wherein there are two carrying devices comprising the first and second carrying devices on the current production line, and adjusting the carrying areas of corresponding to the first and second carrying devices according to the carrying loads comprises:
calculating a difference between the carrying loads of the two carrying device;
if the difference is greater than or equal to a first threshold, adjusting the carrying priority level of the sharing carrying sub-area and the first and second independent carrying sub-areas of the two carrying devices according to the carrying loads.

3. The method as claimed in claim 1 , wherein there are two carrying devices comprising the first and second carrying devices on the current production line, and adjusting the carrying areas corresponding to the first and second carrying devices according to the carrying loads comprises:
calculating a difference between the carrying loads of the two carrying devices;
if the difference is greater than or equal to a first threshold, adjusting sizes of the carrying areas of the two carrying devices according to the difference.

4. The method as claimed in claim 1 , wherein adjusting the carrying areas corresponding to the first and second carrying devices according to the carrying loads comprises:
increasing the carrying area of the second carrying device with the smaller carrying load, decreasing the carrying area of the first carrying device with the larger carrying load, wherein a decreased portion of the carrying area of the carrying devices with lager load is used as an increased portion of the carrying area of the carrying devices with smaller load.

5. The method as claimed in claim 1 , adjusting carrying areas corresponding to the first and second carrying devices according to the carrying loads, comprises:
increasing the sharing carrying sub-area of the second carrying device with the smaller carrying load, and decreasing the first independent carrying sub-area of the first carrying device with the larger carrying load.

6. A material handling system comprising:
a first carrying device and a second carrying and a handling controller, wherein the first and second carrying devices are responsible for carrying materials needed in a production process, and the carrying loads are amounts of materials which are required to be carried by the first and second carrying device, the handling controller comprising a carrying load obtaining module and an carrying adjusting module, wherein,
the carrying load obtaining module is adapted to obtain carrying loads of a first carrying device and a second carrying device respectively on the current production line in a current working period;
the carrying adjusting module is adapted to adjust the carrying areas corresponding to the first and second carrying devices according to the carrying loads, wherein the carrying area of the first carrying device comprises a sharing carrying sub-area and a first independent carrying sub-area, the carrying area of the second carrying device comprises the sharing carrying sub-area and a second independent carrying sub-area, the first independent carrying sub-area is used for the first carrying device independently carrying the material, the second independent carrying sub-area is used for the second carrying device independently carrying the material, and the sharing carrying sub-area is used for both the first and second carrying devices carrying the material; and
wherein the carrying adjusting module comprises:
a first priority adjusting unit adapted to, for the first carrying device with a larger carrying load, adjust the carrying priority level of the first independent carrying sub-area to be greater than the carrying priority level of the sharing carrying sub-area;
a second priority adjusting unit adapted to, for the second carrying device with a smaller carrying load, adjust the carrying priority level of the sharing carrying sub-area to be greater than the carrying priority level of the second independent carrying sub-area.

7. The system as claimed in claim 6 , wherein there are two carrying devices comprising the first and second carrying devices on the current production line, the carrying adjusting module comprises:
a load difference calculation unit adapted to calculate a load difference between the carrying loads of the two carrying devices;
a carrying adjusting unit, if the load difference is greater than or equal to a first threshold, the carrying adjusting unit adapted to adjust sizes of the carrying areas of the two carrying devices according to the load difference.

8. The system as claimed in claim 7 , the carrying adjusting module is configured for adjusting the carrying priority level of each sub-area of the two carrying devices according to the load difference.

9. The system as claimed in claim 6 , wherein the carrying adjusting module is configured for:
increasing the carrying area of the second carrying device with the smaller carrying load, decreasing the carrying area of the first carrying device with the larger carrying load, wherein a decreased portion of the carrying area of the carrying devices with a lager load is used as an increased portion of the carrying area of the carrying devices with a smaller load.

10. The system as claimed in claim 7 , wherein the carrying adjusting module is configured for:
increasing the carrying area of the second carrying device with the smaller carrying load, decreasing the carrying area of the first carrying device with the larger carrying load, wherein a decreased portion of the carrying area of the carrying devices with lager load is used as an increased portion of the carrying area of the carrying devices with smaller load.
