Abstract
In a plating process, a steel plate is conveyed for 20–50 m in the vertical direction for drying, during which it is weakly supported by rollers or other devices, resulting in uneven plating due to vibration and other productivity-reducing factors. We developed a non-contact guide system for a high-speed traveling elastic steel plate in which electromagnetic forces are applied by actuators on the edges of the plate to control its position. Furthermore, we conducted a travelling experiment in which permanent magnets were installed in the linear part of the steel plate to suppress the vibrational effects. We report the results of our experiment and simulations to show the effectiveness of our proposed method. By placing the permanent magnets at the antinodes of vibration in the linear portion, vibration in the loop-shaped part were suppressed. From these results, it is clarified that the guide performance of the loop shaped part can be improved by reducing the vibration of the straight portion.
