Description

Vehicle body production indication system and its operation method {AN AUTOMATIC MANAGEMENT SYSTEM FOR MANUFACTURING CAR BODY AND A METHOD THEREFOR}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automobile body production instruction system, and more particularly, to a system for managing a car body process. More specifically, the present invention relates to a production system of a production facility using a network. The present invention relates to a vehicle body production instruction system that increases productivity by managing work.

In general, the automobile production process is composed of a press process, a car body process, a painting process, and an assembly process. The press process is a process in which the main parts of the car parts are stamped into a mold, and the car body process is a main process manufactured in the press process. The process of manufacturing the vehicle body by assembling the parts and parts attached to the main parts, and the painting process is the process of painting the manufactured vehicle body, and the assembly process is to assemble seats, bumpers, engines and other parts to the painted body. It is a process.

The body process, as described above, is the process of assembling the body parts of the car, which are the main parts of the car, and the parts attached to the body, the body process line assigns these car bodies and the unique numbers of the parts, and Sequence and control the components and body that are introduced into the process.

In a conventional vehicle body process, a worker of a process line receives a sequence instruction from a production manager, which records data on a process input sequence of a part, and carries the sequence instruction to each line of the body process, and the operator of each line receives the sequence instruction. Work on the basis. In addition, when there is a situation such as when a vehicle to be held for production or a problem occurs in a body or a part put into a process, the production manager prepares a list to be inserted or deleted in the sequence order and distributes it to each process. Work on sequence instructions.

By the way, such a conventional body production instruction system manages the management of the vehicle type put into each line of the vehicle body process as a document called a sequence instruction, and the sequence instruction is directly carried by a person. When changing the plan is difficult to respond early, there is a problem that the productivity is low and the accuracy of the work is also reduced.

The present invention is to solve the above problems, and to improve the productivity and efficient production management by automating the body production instruction system.

Can be updated and sent to the server,

The production plan adjustment PC deletes the corresponding vehicle model when a non-production vehicle is generated by the change of the production plan, adds the vehicle model to the production plan when a new vehicle model is generated, and inputs the vehicle model ratio when the ratio between the production vehicle models is changed. In this case, when the defect occurs, the instruction to delete the vehicle model in which the defect occurs can be given.

The production plan coordination PC also includes a monitor for displaying information transmitted to the production plan coordination PC, and the production manager can adjust the production plan online and in real time through the information displayed on the display device.

The operating method of the vehicle body production instruction system of the present invention instructs the vehicle model and the work specification information to the facility according to the production plan indicated by the production plan adjustment PC, and inputs the parts to the facility according to the car model and the work specification, and the instruction is Ethernet It comes down through communication.

In addition, the progress of work in the facility can be reported to the production plan adjustment PC, and the production status information stored in the server can be updated based on the work progress,

The vehicle input sequence instruction is to change the input ratio between models in the vehicle input sequence when the production rate between models is changed, delete the vehicle model in which the defect has occurred in the vehicle input sequence when a defect occurs, and if there is a vehicle model that stops production If there is a vehicle that stops production in the input sequence and adds production, if there is a vehicle that adds the corresponding vehicle in the vehicle input sequence and changes the production specification, it changes the production specification of the vehicle in the vehicle input sequence. Can be.

Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the drawings.

1 shows a vehicle body production instruction system of the present invention.

The vehicle body production instruction system of the present invention is a production plan adjustment PC (10), server (20), switching hub (30), facility automation controller (40), production instruction monitor (50), PLC controller (60), facility ( 70).

The production plan coordination PC 10, the server 20, the facility automation controller 30, and the PLC controller 60 are connected to the switching hub 30 and communicate with each other via ethernet. The production instruction monitor 50 is connected to the facility automation controller 40 to display information sent from the production instruction controller 50, and the facility 70 is connected to the facility automation controller 40 and the PLC controller 60. Control the work of the installation.

An automobile body production process is a process of manufacturing a vehicle body by assembling a body forming a main component of an automobile and parts attached to the body. The vehicle body production process injects the body into a body production line and assembles parts attached to each body in each process in the body production process. Therefore, the vehicle model of the body and the parts attached to the body should match, for this purpose, the order of the body and the parts attached to the body to be put into the facility is managed.

The operation of the vehicle body production instruction system of the present embodiment will be described below.

The server 20 stores information on the vehicle body and the vehicle model put into the facility 70, and information on the work situation in the facility 70.

The production plan adjustment PC 10 determines the order of input of the body and the vehicle to be input to the facility 70 and instructs it by making a data file. The production plan data file instructed by the production plan adjustment PC 10 is updated and stored in the server, and at the same time this instruction is sent to the facility automation controller 40.

This vehicle sequence order of the production plan adjustment PC 10 gives various instructions according to the production plan, giving the following instructions.

In the case of not producing a specific vehicle for a long time or lacking parts of the vehicle, the production plan adjustment PC 10 deletes the vehicle model from the production plan data file, and transmits the production plan data file to the facility automation controller 40. , Update and store in server 20.

When producing a new vehicle or re-producing a vehicle that has stopped production, the production plan adjustment PC 10 adds the vehicle model in the production plan data file, transfers the production plan data file to the facility automation controller 40, The server 20 updates and stores it.

In addition, even when the production order is changed and the ratio of the production vehicle is changed, the production plan adjustment PC 10 changes the data related to the vehicle model in the production planning data file and transmits the production planning data file to the facility automation controller 40. Then, update and store on the server 20.

This instruction of the production plan adjustment PC 10 is issued by the production manager via the production plan adjustment PC 10.
