Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a process management system which enables a plurality of operators to easily carry out manufacturing control, warehousing control and the like in a manufacturing process in which a plurality of processing devices or processing devices are installed.

[0002]

2. Description of the Related Art Conventionally, in a large-scale factory having several kinds of manufacturing processes, a computer in an office and a terminal for the manufacturing process are connected online to manage the start of a product and the like. We have succeeded in increasing the efficiency of the process. However, in the steel material cutting industry, which has a small number of manufacturing steps and a relatively small scale, the rationalizing effect of the above method is hardly seen, and therefore such a system is not introduced at present.

In most cases, a handwriting slip is used to give an instruction to finish a product or to complete a product. Also, this slip is processed by an office worker or an operator who goes back and forth between the office and the manufacturing process many times.

[0004]

Conventionally, inventory management,
As an implementation plan for warehousing management, product processing management, etc., let's not only connect the computer of the office to the terminal of the manufacturing process online, but also give the processing machine such as a band saw machine a communication function with the office computer. Various methods have been considered, such as the processing management method by using the computer, and the inventory management by using the online computer between the automated three-dimensional warehouse and the office.

However, these methods require a large system and cost. It can be supported only by band saws with system functions, and cannot be supported by most general-purpose band saws. There is a strong resistance to PC input due to the aging of operators. Multiple operators cannot grasp the processing status at the same time. Most of them have not been realized because of the above reasons.

[0006] Recently, due to the influence of IT, the ordering system by personal computer management is becoming popular even in the major steel cutting industry. However, this is still limited to office-level IT, and most systems linked to the manufacturing process have not been realized.

[0007] Therefore, in the manufacturing process, the work under the old-fashioned sense of a person is preferentially performed.

The present invention has been made to solve the above problems, and its purpose is to minimize the system,
An object of the present invention is to provide a process management system that can be applied to all processing devices, facilitates operator's input work, and allows all operators to grasp the processing status.

[0009]

In order to achieve the above object, a process control system of the present invention according to claim 1 is installed in an office, and a host computer to which a plurality of work instructions are input, and this host. It is characterized by being equipped with a large-scale display that is connected to a computer and installed in the manufacturing process in the factory, a mobile terminal device that has this large-scale display and a communication function, or a processing device that also has a communication function. is there.

Therefore, first, a plurality of work instructions entered in the host computer installed in the office are displayed on the large-scale display installed in the manufacturing process in the factory. From this, the operator selects one work instruction from the plurality of work instructions and inputs the order acceptance number of the selected work instruction into the mobile terminal device. Further, the NO of the processing device to be used is input, and the information necessary for the processing is displayed on the mobile terminal device. Due to these operations, the display of the work order selected on the large display will be "Processing",
The situation is clear from other operators. In addition, since the information is simultaneously transmitted to the host computer installed in the office, it is possible to know the processing progress (completion of the start) in real time even in the office. After this, when the processing is completed, the operator again inputs the information at the time of finishing the processing to the mobile terminal device, and the display of the work instruction on the large display disappears, and at the same time the information is also displayed on the host computer in the office. Sent. This series of operations enables a plurality of operators to work simultaneously.

Thus, it becomes possible to construct an effective process control system without providing a large-scale three-dimensional warehouse or expensive system processing equipment.

According to a second aspect of the present invention, there is provided a process control system of a host computer installed in an office, to which a plurality of work instructions are input, a portable terminal device having a communication function with the host computer, or communication. It is characterized by being provided with a processing device having a function.

Therefore, first, the plurality of work instructions entered in the host computer installed in the office are displayed on the portable terminal device of the operator. Thereby, the operator selects one work instruction form from the plurality of work instruction forms on the screen of the mobile terminal device. Further, the information required for machining is displayed by inputting NO of the machining device to be used. Due to these operations, the display of the work instruction form selected on the screen of the mobile terminal device becomes "processing", and at the same time, the mobile terminal devices of other operators are also displayed as "processing".
This makes the processing status clear for all operators.
In addition, since the information is simultaneously transmitted to the host computer installed in the office, it is possible to know the processing progress (completion of the start) in real time even in the office. After this, when the processing is completed, the operator again inputs the information at the time of the end of processing to the mobile terminal device. From this, the display of the work instruction on the screen of the mobile terminal device disappears, and at the same time, it is displayed on the host computer in the office. Information is also sent. This series of operations enables a plurality of operators to work simultaneously.

Thus, it is possible to construct an effective process control system without providing a large-scale three-dimensional warehouse or expensive system processing equipment.
