<P>PROBLEM TO BE SOLVED: To provide a vibration bowl feeder of complex vibration type, enhanced in vertical-vibration isolation characteristics without lowering a body supporting function of a vibration insulator. <P>SOLUTION: The vibration insulator 22 elastically supporting the device body of the vibration bowl feeder of complex vibration type is formed in a cylindrical shape, the vibration insulator 22 is arranged in such a posture that an axis direction thereof is a horizontal direction orthogonal to a parts conveying direction, and one end thereof is fixed to a lower vibrator 3 and the another end thereof is fixed to a base 21, wherein spring constants of the vibration insulator 22 in the parts conveying direction and a vertical direction are made to be smaller than a spring constant of the vibration insulator 22 in a horizontal direction orthogonal to the parts conveying direction. Thus, the vertical-vibration isolation characteristics are enhanced without lowering the body supporting function of the vibration insulator 22 in comparison with conventional ones. Consequently, adjustment of vertical-vibration amplitude of a bowl 1 can be easily carried out to impart the most suitable vibration for parts conveyance to the bowl 1. <P>COPYRIGHT: (C)2012,JPO&INPIT |
