Description of the Related Art An RF tag is an information medium that can electrically read and write information a little away from a reader / writer, and is also called an RFID or a non-contact IC tag. Some pallets are made of plastic or metal, but many are made of wood.Attach an RF tag to the pallet so that it can be easily read and written from the RF tag reader / writer attached to the forklift. In many cases, an RF tag is fixed by bonding or the like. Normally, the reader / writer for the RF tag is attached between the claws of the forklift, and when the forklift puts the pawl into the forklift insertion hole of the pallet, the reader / writer for the RF tag approaches the RF tag, and the reader / writer for the RF tag is in the RF tag. An RF tag is used by reading or writing information such as a pallet number.

Ｆタグリーダライタ４であればさらに作業性がよい。Usually, when an article is received in a warehouse or the like in order to manage the article, the article already has a barcode printed on or pasted on the article or on a box containing the article. There is a case where one kind or a plurality of articles are received at a time, or a case where a plurality of kinds are received and managed. The bar code indicating the product number attached to the article is read with a bar code reader, and the number is input with a key. If there is more than one, the bar code is read continuously and the number is input. When there are a plurality of types of articles, the same processing is performed for each type. When carrying the received articles on, for example, a pallet and managing them, an RF tag capable of electrically reading and writing information is attached to a reader slightly away from the pallet, and the barcode data read earlier is written. Usually, a work number is assigned to the receiving work. The bar code reader that reads the bar code and the RF tag writer that writes data to the RF tag may be different from each other. However, as shown in the figure, a portable bar code R
With the F tag reader / writer 4, workability is further improved.

使って機械的に運搬される場合がある。FIG. 1 shows an example in which a pallet is used for carrying and managing the articles, but the articles are relatively large and heavy, and are often carried by a forklift.
When the article is relatively small, a car cart or a container box as shown in FIG. 5 is often used. Even in the case of a car trolley or container box, R
In the case of a car cart with an F tag attached, a person often puts the article into the car cart and then transports it to a storage management place. Further, in the case of a container box, there are a case where the container box is carried by a forklift and a case where the container box is mechanically carried using a belt conveyor or the like.

ぶ。In any case, when transporting goods to the management place,
The work number, the part number code, and the number are transmitted by a host computer (management computer) using a wireless or wired communication line. The host computer searches for the article number code of the article from the article work management information and determines whether it is an article to be received, and in the case of an article to be received, finds a place management number for storing and managing this article for this work, Return to worker. FIG. 4 shows an example of the article work management information in the host computer. In this example, a management place A-0023 is assigned to the work number 00001. At this time, the information of the host computer and the product number code of the received article are collated and confirmed.
The worker is informed of the management place for this receiving work,
For example, when transporting with a forklift, the carrier of the forklift transports the article to a designated management storage location.

業が行われたか確認することができる。Next, when articles stored on a pallet are mainly stored and managed in a warehouse or the like, a management shelf made of metal is used. FIG. 6 shows an article management shelf. It is usually made of iron so that even heavy objects can be loaded, and pallets from two to several levels can be loaded. When an incoming article is carried to this management shelf, an RF tag is attached to the management shelf as shown in FIG. 6 and a management location number is written on the RF tag so that the operator does not mistake the location. Every time, the worker reads this management place number with the RF tag reader, and confirms whether or not it is the designated storage management place. If so,
The transported goods are put on the management shelf. At this time, the work number is added to the RF tag indicating the management place, and the history of the work performed at the management place is left. FIG. 3 shows an example of information of the RF tag on the management shelf. In this example, the management location is A
At the location of -0023, there is a history that the work with the work number 01234 was performed on September 3, 2000. After the work is performed, it is possible to confirm what kind of work has been performed at the management place.
