Everyone is easy to work.Effect of automation technology introduced by Nissan in the assembly process of vehicles | Newswitch by Nikkan Kogyo Shimbun

Nissan Motor is pursuing ease of work at the Tochigi Plant (Kamimikawa -cho, Tochigi Prefecture).The latest automation technology was introduced in the assembly process of the vehicle, and the work was eliminated in a difficult posture.In the casting process of engine parts, a bright and environmentally friendly workplace was realized, and the ratio of women's employees doubled.

"I automated the process that I had been working for almost 8 hours in an unreasonable posture."Nissan's Managing Director Hirata is confident that the introduction of the next -generation production system has been able to approach a workplace where everyone can work.

The main technology "Power Train (Driving Equipment) Batch System" is set up parts such as the engine on a dedicated palette, and the robot assembles the parts group from the bottom of the vehicle.In the past, the conclusion work from under the body, which was forced to have a tight system, has been automated.

On the other hand, apart from the main line that assembles the vehicle, the "sub -process", which assembles the parts to the unit, continues to work by people.Hirata Managing Executive Officer will further improve productivity, saying, for example, doubling the work efficiency of the process, "there is a possibility that a part -timer can work in a workplace."

The cast line of aluminum, which produces the engine cylinder head, has also been transformed.In the past, sand type was hardened with an organic material sticker, but changed to inorganic material.In order to collect organic gas generated by heat during casting, the need for purification equipment that covered the ceiling was unnecessary, realizing an open and bright environment.

In addition, a computer fault shooting device (CT) that can automatically check the inside of the cylinder head has been introduced.In the past, the endoscope was inserted into the head and checked with visualization, but the work load on the inspection was greatly reduced.In addition, a device that automatically reversed cylinder heads with more than 10 kilograms in the appearance inspection.The burden of the work that had been checked while being lifted by hand and rotating was reduced.

Promote a factory creation where everyone can work safely with a small burden from a male -centered workplace.On the casting line, the ratio of women's employees improved to about 20 %.Female employees in charge of the line said, "The workplace has become brighter and it has become easier to work. I don't have to worry about whether it smells, so I can easily go out even at the end of work."Realize.(Ryo Nishizawa)
