Description

[Detailed Description of the Invention] [Industrial field of application] The present invention stores a bar code display container, in particular, a work-in-progress or a product that centrally manages information such as manufacturing specifications, work actual results and work history with a host computer・ Regarding the barcode display container to be transported.

[Conventional technology]

In the conventional production improvement, in order to associate work-in-progress or products with manufacturing specifications, work actual volume, and work history managed by the host computer, put work-in-process or products in a container with a bar code and This was done by reading the bar code with a bar code reader and reporting it to the host computer.

[Problems to be solved by the invention]

The management by combining the barcode number of the conventional storage / transportation container and the host computer described above, the host computer has all the information for the fixed barcode number, and in each station, the station terminal and the host computer exchange information. However, when the host computer goes down, it becomes impossible to carry out production. In order to carry out production even when the system is down, it is necessary to attach the minimum amount of information necessary for production as a paper, and it is possible to have that information in a barcode and replace it with a station, but the barcode can be changed by a person. It was done by printing and putting it in a transparent pocket on the side of the container, which hindered automation.
Furthermore, changing the number requires removing the old bar code and inserting a new bar code, which has the drawback of including the risk of mistaken insertion.

[Means for solving problems]

The barcode display container of the present invention has a display unit capable of displaying an arbitrary barcode on the outer surface, a display control unit for driving the display unit, an electrode for externally driving the display control unit, and a barcode display unit. And a power supply.

〔Example〕

Next, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a perspective view showing a first embodiment of the present invention.

The container 1 is provided with a liquid crystal bar code display portion 2 which is electrically displayed on its side surface, and an electrode group 3 is provided on the front surface of the container 1.

FIG. 2 is an internal block diagram of the barcode display container of the present invention. The display control unit 4 displays the barcode on the barcode display unit 2 according to the signal input from the electrode group 3.
The display power of the barcode display unit 2 is supplied by the power supply 5.

FIG. 3 is a schematic diagram showing an example of data displayed on the bar code display section shown in FIG.
It has a manufacturing lot number 6 indicating a product, a current process 7 and a next process 8, and the current process 7 and the next process 8 at each station.
And update.

Next, the operation will be described in detail.

In a normal production factory, production data such as production specifications are collectively transmitted from a host computer to each station terminal, and in the process, production is performed only by displaying a bar code and production data held by the station terminal. Information such as the actual work volume and work history generated in the process is transmitted to the host computer in a batch.

The bar code display / change on the container is performed on a station-by-station basis, and the station terminal and the electrode group 3 are connected to each other by a signal from the station terminal. Upon receiving the signal, the display control unit 4 displays a barcode corresponding to the signal on the barcode display unit 2, and the display control unit 4 and the barcode display unit 2 display the barcode even after the electrode group 3 is removed by the power supply 5. Is displayed.
The container displayed as a bar code by the station terminal is sent to the transfer line, and the container is recognized by reading the bar code at the transfer line or the next station.

Even if the upper host computer goes down, management / production is performed based on the data in the station terminal based on the current bar code information, and information such as work actual results and work history is transmitted when the host computer becomes popular.

In addition, although not shown in the figure, it is also possible to mechanically display a bar code and to flow it to the same production line to perform production based on the bar code information and the data in the station terminal.

[Effect of device]

The barcode display container of the present invention is connected to a host computer outside the container and is provided with a barcode display part capable of displaying and changing, thereby eliminating the need for humans to print the barcode and replace the barcode. . For this reason, the barcode of the container can be changed automatically without the use of human hands, and at the same time, there is no danger of making a mistake in inserting the barcode. In addition, by incorporating the container of the present invention into an automated line that is managed independently by the station terminal, there is an effect that production can be performed even when the host computer is down.
