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 issues due to mistakes in retrieving the introduction width has been eliminated, resulting in reduced search time for workers and improved efficiency in the picking process.
At the same factory, there was a concern about reducing the high incidence of defects caused by specification differences in picking, and they wanted to establish a system to prevent mis-picking. Since a shutter mechanism that only allows access to the necessary width was effective, they were producing an air-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 to prevent mis-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 size restrictions, as it is the same size as the component indicator 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 Error Prevention Shutter** There have been no issues arising from mistakes in retrieving items at the introduction point, and instead of searching for lit areas like indicator lamps or sensors, workers only need to look for where the shutter has opened. This has reduced the time spent searching and improved the efficiency of the picking process, as noted by feedback received. Additionally, since improvements were made in the picking process, it has also been extended to the remaining supply side.
