<P>PROBLEM TO BE SOLVED: To reliably suppress pitching motion of an article-conveying member in a composite vibration article-conveying apparatus. <P>SOLUTION: In the vibrating article-conveying apparatus in which a middle vibrator 4 is provided between an upper vibrator 2 on which a trough (article-conveying member) 1 is installed and a base 3, the middle vibrator 4 and the base 3 are connected by two leaf springs 5 for horizontal vibration, and the upper vibrator 2 and the middle vibrator 4 are connected by leaf springs 6 for vertical vibration, by providing a vibration isolation rubber 18 between the base 3 and the floor F, and also, providing a weight 19 at each end of the base 3, and by adjusting the mass of the base 3 so that the amplitude of pitching motion of the base 3 can approach the amplitude of relative pitching motion of the trough 1 opposite in phase with respect to the base 3, it is possible to reliably suppress the pitching motion of the trough 1 viewed from the floor. <P>COPYRIGHT: (C)2013,JPO&INPIT |
