Mitsubishi Electric, which aims to be a global and leading eco-friendly company in line with its corporate policy “Changes for the Better” and environmental policy “Eco Changes” and to enrich the society with its technologies, stands out with advanced technology solutions in many different fields, “from in the home to outer space”. The robotic arms of Mitsubishi Electric, which provides added value to Turkey’s leading industrial companies in terms of rapid integration, productivity, flexibility and efficiency, are actively operating in the İzmir/Turkey factory of Dr. Oetker, which strongly focuses on trust and sustainability and is a leader in the market.
While the maintenance of the robotic arm on the production line of Dr. Oetker was carried out on a 6-month basis due to the damage of a specific part, the company requested Mitsubishi Electric Turkey to carry out a study on this issue and optimize it. In the observation, it was predicted that the part had to go to early maintenance due to fatigue effect and it was reported that the vibration source causing fatigue should be investigated.
Sensemore wireless accelerometer was preferred by Mitsubishi Electric and measurements were taken from various points on the production line in three axes. Thanks to its magnetic surface, there was no need for adhesives and their derivatives which were particularly unfavorable for use in a food production facility. The measurements were instantaneously processed on the mobile phone with the mobile application and the measurement results were stored directly in the online environment. The whole procedure was completed in minutes thanks to the facts that all operations were taken from a single point on three axes through the mobile application and that there was no need for bonding. The duration that the line stops during the measurement was reduced to a minimum and the losses that could have been caused by this reason were prevented.
The results show that vibration is released due to insufficiently rigid chassis to which the robot arm is attached, and that the forces generated by the vibration cause fatigue effect.
Measurements taken on a chassis produced by a different manufacturer carrying the robot arm of Mitsubishi Electric were compared with those taken from the Dr. Oetker’s line and the vibration quantities were reported to be very low. These measurements confirm the results obtained.
