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). The memory unit may be provided on the shelf storage unit removably.

Claims

1. An article storage/removal and distribution system, comprising:

a shelf unit for storing at least one article;

a conveying unit for conveying said article to and from said shelf unit;

a terminal unit provided on said conveying unit for transmitting and receiving data signals, said data signals comprising, article data and address data, said address data corresponding to a location of said shelf unit;

a data processing unit remotely provided from said shelf unit and said conveying unit for transmitting data signals to and receiving said signals from said terminal unit;

a memory unit, mounted on said shelf unit and responsive to a call signal transmitted by said terminal unit, for transmitting to and receiving data signals from said terminal unit;

said terminal unit comparing data signals from said memory unit to data signals from said data processing unit.

2. The article storage/removal and distribution system according to claim 1, further comprising:

an article carrying unit for supporting said at least one article, wherein said conveying unit conveys said article carrying unit with said at least one article to and from said shelf unit;

another memory unit mounted on said article carrying units, responsive to said call signal, for transmitting to and receiving data signals from said terminal unit;

said terminal unit comparing data signals received from said memory unit to data signals received from said another memory unit.

3. The physical distribution system according to claim 1, wherein said terminal means comprises a question unit, a central processing unit, a read only memory unit, a random access memory unit, a radio wave transmitter and receiver, a radio wave transmission/reception circuit, a keyboard unit and a display unit.

4. A method of storing/removing and distributing articles of manufacture, comprising the steps:

determining whether a work instruction is present at a terminal unit on a conveying unit;

transmitting a call signal from said terminal unit to a memory unit associated with an article;

transmitting article data from said memory unit to said terminal in response to said call signal;

transmitting said article data from said terminal to a data processing unit remotely provided from said conveying unit;

transmitting address data from said data processing unit to said terminal unit in response to said article data;

moving said conveying unit to or from a shelf unit corresponding to said address data;

transmitting said call signal from said terminal unit to another memory unit mounted on said shelf unit;

transmitting address data from said another memory unit to said terminal;

comparing address data from said another memory unit to address data from said data processing unit;

storing said article on or removing said article from said shelf unit upon coincidence of address data from said another memory unit to address data from said data processing unit.

5. A method of storing/removing and distributing articles of manufacture according to claim 4, wherein said terminal unit comprises interface means including a display unit, for facilitating transfer of data to or from an operator of said conveying unit, further comprising the steps of:

entering said work instruction by said operator through said interface means;

displaying address data from said data processing on said display;

displaying the results of said address data comparison on said display.
