It is linked with.

  The bowl 3 to which the reciprocating vibration of the upper vibrating body 12 is transmitted by the connecting member 25 is torsionally vibrated clockwise in the plate thickness direction of each leaf spring 24 attached at an angle, and is shown in FIG. As described above, the components are conveyed clockwise along the spiral conveying path 4 and delivered to the trough 6 of the linear feeder 9. The spring constant of each leaf spring 24 that supports the bowl 3 is set to be much smaller than the spring constant of each leaf spring 14 that supports the upper vibrating body 12, and the reciprocating vibration of the upper vibrating body 12 by the vibration mechanism It is designed not to interfere.

  The rod-shaped connecting member 25 is provided with an arcuate cutout 25a in the vertical direction and an arcuate cutout 25b in the horizontal direction near both ends, and has flexibility in the vertical and horizontal directions. Therefore, the reciprocating vibration of the upper vibrating body 12 can be smoothly transmitted and converted into the torsional vibration of the bowl 3.

  9A and 9B show a modification of the connecting member 25. FIG. This modification is formed by a plate spring 26 having flexibility in the horizontal direction and holders 27 at both ends thereof, and each holder 27 is provided with an arc-shaped notch 27a for imparting vertical flexibility. Yes.

  As shown in FIGS. 10 to 12, the hopper trough 1 of the hopper 2 is attached to a support column 10b of a base 10 through a support frame 28 formed in an L shape in a horizontal plane. The hopper trough 1 has a lower surface on a substantially diagonal line in the front-rear direction by a pair of leaf springs 29 attached to the front ends of the L-shaped short side and long side of the support frame 28 in a horizontal direction perpendicular to the front-rear direction of the hopper trough 1.
