 note = {The setting method of vibratory feeders can be classified into three types, i.e. fixed type, semi-floating type and floating type. In this paper, the relations between setting modes and dynamic characteristics are clarified theoretically. The main results are as follows : 1) If the stiffness of vibration isolator is less than about one-fifth of that of feeder spring, the vibratory characteristics of semi-floating type can be approximated to those of the floating type feeder. Therefore, in the case of an ordinary vibratory feeder, it is sufficient to consider only the fixed type and the floating type. 2) The resonance frequency of floating type feeder is expressed as √1+β・f, where β is the ratio of the equivalent-mass of bowl (or trough) to that of base and f is the resonance frequency when the base is fixed. 3) If the fixed type feeder is set on vibration isolator, the vibration amplitude of bowl decreases remarkably, since the feeder is ordinarily used at the resonance of the mechanical system. 4) This decreasing tendency becomes remarkable with increase of β and reduction of damping factor. 
In this paper, the relations between setting conditions and vibration isolation are also discussed. 
It is confirmed that the above theoretical results agree well with experimental ones.},
