Introducing a case study of the Poka-yoke product "Poka-yoke Shutter" used in assembly factories.
Mistake-proof shutter
We will introduce a case where the occurrence of defects due to mistakes in retrieving the introduction width has been eliminated, reducing the time workers spend searching and improving the efficiency of the picking process.
At the same factory, there was a concern about reducing the high incidence of defects due to specification differences in picking, and they wanted to establish a system that prevents incorrect picking. Since a shutter mechanism that only allows access to the necessary width was effective, they had been manufacturing an air cylinder-operated shutter in-house. However, the in-house air-operated shutter posed issues with high costs for mass production and maintenance. Therefore, by switching to our electric shutter, it became easier to expand to other factories and lines due to the advantages in cost and maintenance. [Case Summary] ■ Issue - They wanted to establish a system that prevents incorrect picking. ■ Result - By switching from in-house air-operated shutters to mass-produced electric shutters, it became easier to expand to other factories and lines due to the benefits. ■ Advantages - Costs were reduced to one-third. - It can be installed in locations without restrictions, as it is the same size as the component indication lamp. - Layout changes are easy. - It has lamp displays, making it easy to see. - The mechanism is simpler compared to air-operated systems, significantly reducing failures. *For more details, please refer to the PDF document or feel free to contact us.

basic information
**Results of Introducing the Anti-Mistake Shutter** There have been no malfunctions due to retrieval errors at the introduction entrance, and instead of searching for the lit areas of the indicator lamps and sensors, workers only need to look for where the shutter has opened, which has reduced their search time and improved the efficiency of the picking process. Additionally, since improvements have been made in the picking process, we were able to expand this to the remaining supply side as well.
