HINODE,Ltd. which manufactures lifeline-related cast iron products such as manhole covers for water and sewage system
Yaskawa’s robots are used to deburr the frame of manholes.

The Saga Plant of HINODE manufactures various types of manhole covers and frame. Conventionally, deburring work has been done by hand, but due to the heavy materials and the environment in which sparks and iron powder fly, it has put a burden on workers.
The installation of Yaskawa robots has reduced the burden on workers and shortened the cycle time by halving the work time, while also stabilizing the quality.

In addition, we were able to manufacture a wide variety of products without altering the arrangement of the robot’s work.

We decided to introduce a robot by Yaskawa based on our belief that robots with minimal preparation and automated facilities have an advantage in responding to our strength of “low-volume, high-variety production.”
We had a lot of discussions with the person in charge of Yaskawa about the problem of how to accurately and flexibly handle the burr that is removed by a considerable amount of weight from the receiving frame compared to the cover, and how to make the robot handle the burr against the grindstone. We also studied how to achieve multi-product production with jigs and tools without changing the arrangement of robotic work.
