<p><P>PROBLEM TO BE SOLVED: To suppress the occurrence of the vertical vibration caused by the horizontal vibration at low cost in a composite vibration-type component conveying device. <P>SOLUTION: In the vibration-type component conveying device configured such that an intermediate vibrator and an upper vibrator to which a trough (a component conveying member) is mounted are coupled by a horizontally-directed second leaf spring (an elastic member for vertical vibration) with the intermediate vibrator and a base coupled by a vertically-directed first leaf spring (an elastic member for horizontal vibration), the vertical natural frequency F<SB POS="POST">v</SB>of the trough is adjusted so as to be larger than the horizontal natural frequency F<SB POS="POST">h</SB>by≥5 Hz. Thus, a big difference occurs between the amplitude V<SB POS="POST">h</SB>of the horizontal vibration and the amplitude V<SB POS="POST">v</SB>of the vertical vibration in the horizontal natural frequency F<SB POS="POST">h</SB>of the trough, thereby reducing the amplitude of the vertical vibration caused by the horizontal vibration. Consequently, it is possible to easily achieve the desired vibration suitable for the component conveyance. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
