Lead Racers among the Circles
Circle name is consciously chosen from notorious origin to eliminate 3K (Kitsui = Demeaning, Kitanai = Dirty, and Kiken = Dangerous) workplace. As you can see from the pictures, they have put lots of time and energy for Initial Clean-up. Through efforts in a few months, they have totally swept away 3Ks in the workplace.

They once cleaned dust by hand wearing cotton work glove. Now they let this automatic cleaning unit to sweep dust away. This Karakuri utilizes motion of vibrating machine. Why cotton work glove? From their experiences, the glove is better than bloom or waste cloth.
Once we made it with efforts, show what we did. So they made a news flyer in brilliant colors.
This is the award winning Karakuri Kaizen. Part of pipe is replaced with acrylic, and it is a visualization of cooling water flow. A bobber is in it, and indicates proper level of cooling water.
Before this kaizen, it was hard to check the direction of on-off valve. Now, after the kaizen, we can check it from a distance. The indicators are linked with movement angle (90 degree) of valve.

Flashing eyes call attention when too much force is applied to crash the bottle. Never at night.
Operators manually assisted to fold 3000 to 4000 cardboard tops at the caser machines. This was too much burden for them, so the guide with small plates was made. This has achieved zero defects of the top folding.
