Abstract
This paper describes the experimental study of the characteristics of a new non-contact type suction device. The present study has been carried out for handling technology in various environments. The main aim was to obtain high suction force in non-contact. We propose a new non-contact type suction device. The jet of nozzle ring flows along surface of device by coanda effect. Eject effect caused by the coanda effect decreases pressure in inside area of nozzle ring. The pressure brings strong suction force. The force distribution vs. parts alignment refers optimal size and condition. This time, we confirmed the suction force by the new method. However, the improvement is depended on suitable alignment. That is suggested that we have to consider relation between coanda and eject effect in thin space put between device and object.
