Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an outsourcing management system in the field of production management, and more particularly to an outsourcing management system for connecting an outsourcing factory to an own factory via a communication network.

[0002]

2. Description of the Related Art Conventionally, in this type of outsourcing management system,
On the outsourced factory side, physical information such as order number and lot number was input with a keyboard or bar code, and it was sent to the in-house factory side as wired data via outsourced data.

Regarding the above processing operation, a person in charge at an outsourced factory taps a keyboard of a terminal as an input operation or simply inputs a bar code reader with a bar code for a small amount of information such as an order number or a lot number. The outsourced data input in this way is stored in a computer (outsourced computer device) in the outsourced factory and transmitted to the in-house factory once to several times a day.
A process management person uses a progress management system built on a computer (company computer device) in the company's factory to grasp the progress of the work in the outsourced factory.

[0004]

In the above-described conventional outsourcing management system, a person must intervene in the case of keyboard input in the work of inputting physical information, and in the case of bar code input, the bar attached to the actual product. There are many restrictions on the positional relationship (distance, angle, etc.) between the code and the bar code reader, and the information capacity is limited to several tens of bytes.

Further, in the conventional subcontract management system, there is a problem that the machining information may reach the subcontract factory by a route different from that of the actual product, and it is not easy to synchronize the machining information with the actual product.

Further, in the conventional outsourcing management system, new quality information generated at the stage of assembly processing, adjustment inspection, etc. of an outsourcing factory is accumulated in a form separated from the actual product or disappeared without being saved. However, there is a problem that it is necessary to newly set up an inspection process at our own factory.

In view of the above points, an object of the present invention is to provide an outsourcing management system capable of automating progress management of work in an outsourcing factory and grasping further various information contents. ..

As the transmission method, there are methods such as "electromagnetic coupling type", "induction electromagnetic field type", "microwave type" and "optical type".

Incidentally, in the case of the process line 25 for assembling and inspecting the engine, it is preferable that the transmission range is several meters because the work environment is easily soiled and the engine block 31 itself is large. Therefore, the microwave type or induction electromagnetic field type is used.

Further, an optical transmission system can be used if the process line 25 is capable of maintaining a clean environment to some extent, and this optical system has higher directivity than the microwave system or the induction electromagnetic field system. Although it is possible to perform R / W operation through plastic or the like, it also has a disadvantage that environmental resistance is low.
