Working hour loss statistics method

Abstract

The invention provides a working hour loss statistics method. The method includes the steps that 1, the takt time of products in each process is set in a system in advance, and preset production interval time deltaT1 is obtained; 2, manual or automatic scanning is conducted in each process of the products, and the station-crossing time of each product in the current process is recorded by scanningthe identification code of each product; 3, according to the recorded station-crossing time of two successive products, a system works out that the actual production interval time deltaT2 of the current process is the result obtained by subtracting the station-crossing time Tn of the current product in the process from the station-crossing time T(n+1) of the next product in the process; 4, it isworked out that the loss time deltaT of the same product in each process is the result obtained by subtracting the preset production interval time deltaT1 from the actual production interval time deltaT2. In the method, a scanning mode is mainly adopted for recording time, the actual interval time of the processes of each product is automatically worked out, and then the working hour loss of all products in all processes of a production line is obtained.

Description

Technical field [0001] The invention relates to a management method on a production line, in particular to a statistical method of working hours loss. Background technique [0002] Statistic of working hours loss is one of the important management methods of the production line. Through working hours loss statistics, we can know which production link has working hours and the degree of loss, and provide a data basis for subsequent targeted improvement measures. [0003] Nowadays, the calculation of the production line working time loss in production uses special manual recording. This traditional method will only attract attention and record the downtime when the production line has been stopped for a long time, and a special manual recording method With many drawbacks, it is impossible to accurately and comprehensively count the actual working time of the production line, and thus cannot obtain the actual working hours. Summary of the invention [0004] The technical problem to be...

[0003] Nowadays, special manual records are used to calculate the working time loss of the production line in production. This traditional method will only attract attention and record the stop time when the production line stops working for a long time, and the special manual recording method There are many disadvantages, and it is impossible to accurately and comprehensively count the real working time of the production line, and thus the actual working hours loss cannot be obtained
