[Industrial application field]

The present invention relates to a work process analysis/standard time setting device, and more specifically, the present invention relates to a work process analysis/standard time setting device that makes it possible to automatically perform processes from work process analysis to standard time setting based on CAD data. Regarding equipment.

As the number of models increases and product life cycles become shorter, it is extremely important to maintain standard data such as detailed work process flows and standard times for each work process in order to improve the efficiency of assembly plants. It becomes a point. Furthermore, by utilizing this reference data, it becomes possible to optimally design an assembly line such as the tiNtc line.

Therefore, there is a strong demand for the development of a support tool for an assembly line work manager to establish reference data when designing a line.

[Prior art] The conventional standard data creation method analyzes the work process based on product design data and the product itself to create a work process flow, and then uses measuring instruments such as a stopwatch. A common procedure is to use this method to set standard times for each work process.

For example, a conventional work process flow is shown in FIG. In this figure, the mark in the figure is the part name, the number in parentheses near the mark is the part quantity, the O mark is the work name, and the number near the ○ mark is the standard time (minutes). This represents the process of tightening 81 screws in a standard time of 0.52 minutes, reversing them in a standard time of 0.11 minutes, and then inserting 81 parts in a standard time of 0.06 minutes.

This type of processing is important in building an efficient line.
When manufacturing new products or revising design data,
Must be done every time.

[Problem to be solved by the invention]

However, in this conventional standard data creation method, a work manager measures the time it takes to actually print a prototype using a measuring device such as a stopwatch, and calculates the standard time for each work process. In addition to having limitations in measurement accuracy, it also takes a considerable amount of time to create standard data such as work process analysis and standard time settings, so by the time the standard data creation is complete, production has already begun. There was a problem that standard data could not be provided in a timely manner at the time of line design. Furthermore, since the technical level of the process analysis method, standard time setting method, etc. differs depending on the work manager who creates the standard data, there is a problem in that the required results also vary considerably in terms of accuracy.

Therefore, the present invention aims to automate a series of processes from work process analysis to standard time setting, speed up each process, and provide accurate reference data in a timely manner during line design. The purpose is to provide a time setting device.

[Means to solve the problem]

In order to achieve the above objectives, the work process analysis/standard time setting device according to the present invention determines the order of parts assembly based on the part hierarchical structure of CAD data, and determines the work necessary for parts assembly that should be performed by a worker for each assembly process. It is equipped with a work process analysis means that can set a process and visually modify the work process, and a standard time setting means that sets a standard time for each determined work process, and it is equipped with a work process analysis means that allows you to visually modify the work process, and a standard time setting means that sets a standard time for each determined work process. The process up to setting the standard time is automatically performed.

[Effect]

The present invention includes a work process analysis means that determines the order of parts assembly based on CAD data and sets a work process to be performed by a worker for each assembly process, and a standard time that sets a standard time for each determined work process. Two main modules of configuration means constitute the system. In addition, by making each module independent and storing the processing results of each module in a common database, we achieve high-speed processing and provide versatility and scalability, while displaying the work process flow on the screen provides a visual This allows for modifications.

Therefore, a series of processes from work process analysis to standard time setting are automated, and each process is accelerated. As a result, accurate reference data is provided in a timely manner during line design.

[Explanation of principle]

First, the present invention will be explained in detail. The present invention aims to systemize a series of processes by treating them as two main modules, a work process analysis section and a standard time setting section, and to make each module independent and store the processing results of each module in a common database. This makes it possible to achieve high-speed processing, as well as provide versatility and expandability (see FIG. 1, which will be described later).

The work process analysis section uses the parts hierarchical structure of CAD data to determine the parts assembly order based on work conditions and past performance data. Furthermore, the work process necessary to assemble the parts is set using a knowledge database that incorporates the know-how of work managers and on-site workers as rules. In addition, by displaying the work process flow on the screen,
This allows for visual correction (see Figure 5, which will be described later).

By importing the standard time estimation table as a calculation formula with parameters, the standard time setting section not only outputs highly accurate work time data, but also enables automatic processing and high-speed processing.
