Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for analyzing the operation state of an operation target, for example, a production machine or a worker in a production process, an operation state analysis system for implementing the method, and an operation state analysis system using the system. It relates to a management device.

[0002]

2. Description of the Related Art Generally, analysis of operation and time in a production process is known as a basic technique in production engineering. As a typical example, there is a method of using a stopwatch on a production line to analyze motion, that is, to observe and analyze the movement of workers included in the work in detail, to eliminate unnecessary movements, and to improve the operation procedure and combination. is there.

[0003] However, this method requires a great deal of experience and knowledge, and is accompanied by mental and psychological distress for both the worker and the observer who are collecting the data. Trying to get it is not only very nervous, but also time-consuming. Therefore, even though the necessity and effect of its implementation were recognized, this method was not fully utilized as a practical problem.

Further, with the spread of video cameras and image reproducing devices, the contents of work are photographed with a video camera, and the work time is measured using a stopwatch if necessary, and the image obtained in this way is reproduced by the image reproducing device. There has been proposed a method of analyzing operation and time while improving and instructing a work state based on the analysis data, and also storing the analysis data.

However, in this method, since the operation and time are analyzed while reproducing the image obtained by the video camera with the image reproducing device, it is necessary to repeat the operation of the image reproducing device such as reproduction and rewinding. The more detailed the operation and time analysis, the longer the analysis work takes. Further, the analysis of the operation and the time requires measuring the time for each element, writing the result on a sheet, and inputting the result to a spreadsheet software or the like, which is time-consuming and cumbersome. Further, since the analysis results of the operation and the time are stored on a video tape, recording paper, a data disk, or the like, data management is troublesome. Furthermore, it is very troublesome to find a desired portion from the analysis result of the operation and the time. Further, such a conventional method has a disadvantage that useless operation in the work content to be managed cannot be cut, repeated, or reproduced from a set rating value.

The measurement of the invalid operation is started by left-clicking the video screen on the video display screen 15 or clicking the PLAY button, and is ended by clicking the video screen on the video display screen 15 left or right. Can be done. In this case, the moving image on the moving image display screen 15 does not stop, the color of the display frame on the moving image display screen 15 changes to light blue, and the process returns to the normal analysis. Thus, in the measurement of the invalid operation, the time from clicking the moving image screen on the moving image display screen 15 to clicking again is measured as the invalid time. In addition, the number of invalid operations in this operation element is displayed in the display column 17.

When there is no invalid operation during the execution of the motion analysis, the moving image screen can be returned to the start time position of the operation element by clicking the button of the moving image return button 12 to the head position of the current element. On the other hand, if there is an invalid operation during the execution of the motion analysis,
By clicking the button to the invalid invalid end position, the moving image screen can be returned to the final invalid operation end position. When an operation element is deleted due to an operation error or the like, the operation can be executed by clicking the cancel button 11. If you cancel all motion elements,
If all the motion elements of the cycle currently being analyzed are deleted and if the last motion element is canceled, only the last motion element of the cycle being analyzed is deleted, and the video will contain only one motion element. Return to end time position. In addition, even when an invalid operation of the operation element being analyzed is deleted due to an operation error or the like, the operation can be executed by clicking the cancel button 11. In other words, if all invalid operations are canceled, all invalid operations currently being analyzed are deleted, and if the final invalid operation is canceled, the final Only the invalid behavior of is removed.

To set a rating value, click on the rating value input field to display a cursor, for example, 50 to 50.
By key input within the range of 200%, the total operation time and the standard time calculated from the rating value are displayed, and this rating value can be changed even during analysis reproduction.
