For example, the area P1 of the temporary component placement location 400 is the area of the shipping order No. 1 in the direction of the assembly factory 1, and the area P2 is the area of the shipping order No. 2 in the direction of the assembly factory 1. Similarly, for example, the area S1 is an area of the shipping order No. 1 in the direction of the assembly factory 2, and the area S2 is an area of the shipping order No. 2 in the direction of the assembly factory 2.
[0030]
The host computer 202 is a computer that manages the parts shipment process 30 ′, and stores part set management information 205 including the type, quantity, cart number, shipping direction, and shipping order of parts to be collected as a part set. The host computer 202 also includes wireless communication means (not shown) that collects barcode information from the barcode reader 300 and transmits work instruction information to a device or the like installed on the lower side. Yes.
[0031]
Further, carts 101 to 103 equipped with self-propelled driving means are installed at the parts receiving place 100, which is a parts transport address (shipping direction) transmitted from the host computer 202 via wireless communication means. It is possible to load and move the loaded cargo automatically in the area of the temporary component storage location 400 corresponding to the shipping order).
[0032]
FIG. 3 is an example of the component set management information 205. This is set by a production management computer (not shown) or the like that manages information related to all product production, such as the manufacturing process of the product and the ordering of parts positioned higher than the upper computer 202. The shipment schedule is set according to the item number as the part type, quantity, cart number to be loaded, shipping direction, shipping order, loading completion flag, and the like.
[0033]
Returning to FIG. 1, when the worker 140 reads, for example, the barcode 121 attached to the box a from the box unloaded at the parts receiving place 100 using the barcode reader 300, this reading is performed. Information of information (in this case, the number of parts a100) is transmitted to the host computer 202 via wireless communication means (not shown).
[0034]
Based on the read information (100 parts a) sent from the barcode reader 300, the host computer 202 searches the part set management information 205 for information corresponding thereto. In this case, in the component set management information of FIG. 3, the information of item number 1 matches the read information (100 components a).
[0035]
Therefore, the host computer 202 transmits the cart number (in this case, 101) managed in the field of the item number 1 to the bar code reader 300 via the wireless communication means.
[0036]
The bar code reader 300 displays the cart number 101 transmitted from the host computer on the display means 301, and the worker 140 loads the box a onto the cart with the cart number 101 displayed on the display means 301.
[0037]
When the loading is completed, the worker 140 presses a loading completion button 302 provided in the barcode reader 300. Thereby, the barcode reader 300 notifies the loading completion message to the host computer 202 via the wireless communication means.

[0039]
The worker 140 performs the above-described work on all boxes that arrive at the parts receiving place 100.
[0040]
The host computer 202 always monitors the loading completion flag. For example, when all the loading completion flags of the part types corresponding to the carriage 101 are “1”, all the boxes to be loaded on the carriage 101 are loaded on the carriage 101. Judgment is made, and a parts conveyance address that designates the area of the parts temporary storage location 400 to which the parts loaded on the carriage 101 are to be transferred is transmitted. In this case, in the parts set management information of FIG. 3, information (P, 1) set in the fields of the shipping direction and shipping order of item numbers 1 to 3 is the parts transport address transmitted to the carriage 101.
[0041]
When the carriage 101 receives the parts conveyance address (P, 1), it loads the loaded luggage in the corresponding area of the parts temporary storage place 400 and moves by the self-propelled driving means.
[0042]
In the parts set shipping system of the present invention, by repeating the above-described operation in such equipment, parts delivered to the parts receiving place 100 for each kind are replaced with different kinds of parts required at each assembly factory. It is possible to collect them as a set and temporarily place them in each area of the parts temporary placement location 400 according to the shipping direction and the shipping order. Each component set temporarily placed here is shipped to various directions as needed upon arrival of the shipping truck 501.
[0043]
In this way, the parts can be received as a set without individually arriving at the assembly factory 1 and the assembly factory 2, and the parts can be flowed to the production line immediately after solving the parts set.
[0044]
Further, in the above example, the area P1 of the temporary component placement location 400 is the area of the shipping order No. 1 in the direction of the assembly factory 1, and the area P2 is managed as the area of the shipping order No. 2 in the direction of the assembly factory 1. For example, when the number of parts shipped to the assembly factory 1 is large, the areas P1 to P3 are set as the area of the shipping order 1 in the direction of the assembly factory 1, and the area P4 is set as the area of the shipping order 2 in the direction of the assembly factory 1. It is also possible to manage. That is, each area of the temporary component placement location 400 is flexibly supported and managed by the shipping direction, the shipping order, and the shipping amount.
[0045]
