Abstract

A combination weighing apparatus comprises a distributing table having a conical vibrating surface, a cap disposed above an apex portion of the distributing table, a plurality of supply troughs arranged radially around the distributing table with a downward gap S interposed therebetween, and a rotary stirrer for stirring articles supplied from the distributing table to the plurality of supply troughs. The rotary stirrer includes a stirring arm extending from the apex portion of the distributing table along the vibrating surface and a leading end stirring plate disposed on the leading end side of the stirring arm. The leading end stirring plate is arranged in the gap.

First claim

What is claimed is:

1 . A combination weighing apparatus comprising:
a distributing table having a conical vibrating surface; a conical body disposed above an apex portion of the distributing table; a plurality of radial parts arranged radially around the distributing table with a downward gap interposed therebetween; and a rotary stirring unit that stirs articles supplied from the distributing table to the plurality of radial parts; wherein the rotary stirring unit includes: a stirring arm extending from the apex portion of the distributing table along the vibrating surface; and a leading end stirring plate disposed on the leading end side of the stirring arm; and wherein the leading end stirring plate is arranged in the gap.

2 . A combination weighing apparatus according to claim 1 , wherein the leading end stirring plate is shaped along the gap and a part of the radial parts.

3 . A combination weighing apparatus according to claim 1 , wherein the stirring arm is provided with a middle stirring plate having a surface perpendicular to the vibrating surface.

4 . A combination weighing apparatus according to claim 3 , wherein the leading end stirring plate is formed integrally with the middle stirring plate.

5 . A combination weighing apparatus according to claim 1 , further comprising a plurality of vibration sources that impart different kinds of vibration to the distributing table.

6 . A combination weighing apparatus according to claim 1 , further comprising a driving source that rotates the rotary stirring unit normally and reversely.

7 . A combination weighing apparatus according to claim 1 , wherein three such stirring arms are provided.
