Abstract

A physical distribution system having a shelf storage unit for storing at least one article; a conveying unit having a terminal unit for conveying an article to and from the shelf; a memory unit for storing and retrieving data from the terminal unit, data relating to the article and data relating to the shelf address; and a data processing unit for transferring data relating to the storage/removal of article(s) to and from the terminal unit of the conveying unit; wherein the memory unit is mounted on the article(s) or is mounted on an article carrying unit which is used for carrying the article(s).

Claims

1. A physical distribution system comprising:

at least one article storage shelf for storing article carrying units each carrying an article;

an article conveying unit, having a terminal unit, for conveying said article to and from said article storage shelf;

a first memory unit capable of storing and retrieving without contact data relating to said article from said terminal unit of said article conveying unit, said first memory unit being provided to said article carrying unit;

a second memory unit capable of retrieving without contact data relating to an address of said article storage shelf from said terminal unit, said second memory unit being provided to said article storage shelf; and

a remote data processing unit for transferring and processing

the data relating to the storage/removal of said article between said article conveying unit and said terminal unit to control storage condition of said articles in said article storage shelf, wherein during conveying said article in a warehouse, said terminal unit of said article conveying unit reads out the data relating to said article, which has been stored in said first memory unit to be transmitted and stored in said data processing unit, the data relating to the address of said article storage shelf to which said article carrying unit is placed is transmitted to said terminal unit to thereby move said article conveying unit to an aimed shelf arrival of said conveying unit to the aimed shelf, data, and upon arrival of said conveying unit to the aimed shelf, the address data of said shelf which has been stored in said second memory unit is read out to be subjected to comparison with the shelf address data from said data processing unit to thereby ensure that the data stored in said data processing unit and said article on said storage shelf coincide with each other.

2. A physical distribution system comprising:

at least one article storage shelf for storing article carrying units each carrying an article;

an article conveying unit, having a terminal unit, for conveying said article to and from said article storage shelf;

a first memory unit capable of storing and retrieving without contact data relating to said article from said terminal unit of said article conveying unit, said first memory unit being provided to said article carrying unit;

a second memory unit capable of retrieving without contact data relating to an address of said article storage shelf from said terminal unit, said second memory unit being provided to said article storage shelf; and

a remote data processing unit for transferring and processing the data relating to the storage/removal of said article between said article conveying unit and said terminal unit to control storage condition of said articles in said article storage shelf, wherein a call signal is transmitted from said terminal unit to said data processing unit to retrieve the data relating to the removal of said article and relating to the address of the shelf, and after the conveying unit is moved to a position instructed according to the shelf address data, the shelf address data stored in said second memory unit is read out from said terminal unit to be subjected to comparison with the shelf address data in said data processing unit, to thereby ensure coincidence of the data relating to the removal of said article and the article stored in the shelf.

3. A physical distribution system, comprising:

an article storage shelf for storing article carrying units, each of said article carrying units carrying at least one article;

a remote host computer system having a central processing unit operatively associated with a first memory unit, a first data display unit, a first data entry unit, and a first data transmission/reception device;

a terminal unit having a question unit operatively associated with a second memory unit, a second data display unit, a second data entry unit, and a second data transmission/reception device, said terminal unit being installed on an article conveying unit for conveying said article carrying units to and from said article storage shelf;

a first answer unit, mounted on said article storage shelf, for transmitting and receiving address data relating to a location of said article storage shelf, said first answer unit having a third memory unit for storage of said address data and for read out of said address data without physical contact by said terminal unit and by said host computer system; and

a second answer unit, mounted on each of said article carrying units, for transmitting and receiving descriptive data relating to the article carried on the respective article carrying unit, said second answer unit having a fourth memory unit for storage of said descriptive data and for read out of said descriptive data without physical contact by said terminal unit and by said host computer system.
