In addition, each time transport is carried out, communications such as transport content inquiries and transport instructions are performed with the host computer, so there is a problem that the amount of communication increases as the amount of transport increases, and when the host computer goes down, transport The problem was that it became impossible to do so.

[0006] Work conditions such as setup information, which is additional information on the transported object, are registered in advance in the host computer, and the worker recognizes the work conditions from the terminal.
When there is a change in the content, there is a problem in that the worker may not recognize the changed content of the work conditions output from the terminal.

[0007]

[Means for Solving the Problems] The transport management/control system in a production factory of the present invention includes a transport vehicle that transports a transported object, and a transported object delivery station that transfers the transported object between the transport vehicle and the transport vehicle. a storage medium that is attached to the conveyed object and stores conveyance route information; and an information input/output device that is attached to the conveyed object delivery station and the conveyance vehicle and reads and writes the contents of the storage medium.

[0008]

Embodiments Examples of the present invention will be described in detail with reference to the drawings.

FIG. 1 shows a system configuration diagram of an embodiment of the present invention. As shown in FIG. 1, this system includes a host computer 1, a transport vehicle 2, an object delivery station 3, an object 4, a storage medium 5, and an information input/output device for inputting and outputting information to and from the storage medium 5. It is composed of an output device 6.

A storage medium 5 storing transport route information is attached to the transported object 4, and when the transported object 4 is placed at the transported object delivery station 3, the transport vehicle 2 comes to pick up the transported object 4. Note that the storage medium 5 stores transport route information in a format as shown in FIG. An information input/output device 6 is attached to the conveyance vehicle 2 and the conveyed object delivery station 3, so that the contents of the storage medium 5 can be read and written. In addition, when it is necessary to convey work conditions such as setup information to workers in the process at the destination, the information input/output device 6 is used to write the work conditions in the storage medium 5 so that the transport vehicle 2 can convey the work conditions. When the article 4 is placed at the article delivery station 3, the operator is informed that there are work conditions related to the process at the destination. As a result, the workers in each process check the presence or absence of the working conditions before starting the work, and then carry out the work.

The operation method of this embodiment and the exchange of information with the host computer are shown below in FIGS. 2 and 3.

[0012] Transport route information of the transported object 4 is registered in the host computer 1, and transmitted to the information input/output device 6, and an identification code and process information are written in the storage medium 5 as shown in FIG. Then, the storage medium 5 is attached to the conveyed article 4, and the conveyed article 4 is placed on the conveyed article delivery station 3.

When the conveyance vehicle 2 picks up the conveyed article 4 from the conveyed article delivery station 3, it uses the information input/output device 6 to recognize the conveyance route information f in the storage medium 5, and carries it out.

[0014] The transfer station 3 includes a transfer carriage 2.
When the conveyance object 4 is taken over, a conveyance start report c is made based on the contents of the storage medium 5 attached to the conveyance object 4. Furthermore, when the transport vehicle 2 unloads the transported object 4, the storage medium 5
An end flag is set in the conveyance route information as shown in FIG. 4 to record that conveyance to that process has ended. Then, a conveyance completion report d for that process is performed.

[0015] Next, an operating method in the case where re-construction occurs and the storage medium 5 is transported by a transport route different from the transport route set at the beginning will be described below. First, storage medium 5
The conveyance route information in the storage medium 5 attached to the conveyed object 4 is changed using the information input/output device 6 that reads and writes the contents of. At this time, a change flag is set on the conveyance route information added or changed to the storage medium 5, as shown in FIG. 4, to indicate that the conveyance route information is different from the initially set conveyance. and,
Transport is performed using the procedure described above.

[0016]

[Effects of the Invention] As described above, in the present invention, when re-construction occurs and the object is transported by a different transport route than the original transport route, the contents of the storage medium attached to the transported object are corrected. This has the effect that the conveyance route can be easily corrected by simply using the above method. In addition, since the storage medium attached to the transported object is used to directly instruct the transport vehicle to transport the transported object, when the amount of transported objects increases, the communication volume of the host computer increases significantly compared to the conventional case. It has the effect of not doing so. Further, even when the host computer goes down, there is an effect that the transportation is not interrupted. Furthermore, by writing information to be communicated to workers in the destination process, such as setup information, on the storage medium, work instructions can be easily given or changed without the intervention of a host computer.

[0017] In the present invention, performance information such as the transport history of the transported object and changes in work conditions is recorded in the storage medium through a series of transports, so management and aggregation of performance information can be performed in real-time processing or batch processing. It has the effect that it can be carried out.
