ABSTRACT:
BACKGROUND OF THE INVENTION
This invention relates to a system for checking and sorting an article in a physical distribution center.
In general, a sender attaches a tag label to an shipping article on shipping the article. A shipping Address and name is written as a tag name on the tag label. The shipping article is sorted on the basis of the shipping name in a physical distribution center. Furthermore, the owner may transmit shipping data to the physical distribution center by an on-line system. The shipping data is used for specifying the shipping article. In the physical distribution center, it is necessary to check the shipping name with the shipping data before the shipping article is shipped to a receiver.
However, the above-mentioned check is carried out by human hands. As a result, it is difficult to efficiently ship the shipping article to the receiver in the physical distribution center with a low cost.
SUMMARY OF THE INVENTION
It is therefore an object of this invention to provide a system for rapidly checking and sorting a shipping article with a low cost.
Other objects of this invention will become clear as the description proceeds.
According to this invention, there is provided a system for sorting an article on shipping the article. The article has a tag label in which a symbol is written. Furthermore, the article has an ID tag in which tag information is written. The system comprises symbol reading means for reading the symbol out of the tag label to produce read-out symbol information, ID tag writing means for writing the tag information in the ID tag in accordance with the read-out symbol information, conveyer means for conveying the article therethrough, first detecting means for detecting the article conveyed on the conveyer means to produce a first detection signal, second detecting means located downstream of the first detecting means for detecting the article conveyed on the conveyer means to produce a second detection signal, and control means for controlling the symbol reading means in response to the first detection signal to make the symbol reading means read the symbol out of the tag label, the control means controlling the ID tag writing means in response to the second detection signal to make the ID tag writing means write the tag information in the ID tag in accordance with the read-out symbol information. The article is sorted on the basis of the tag information written in the ID tag.
