1. An automatic combination weighing apparatus comprising:
- a conical dispersion table;
means for driving said dispersion table to cause articles fed on said dispersion table to move outwardly and circumferentially thereon;
a plurality of feed troughs radially arranged around said dispersion table to receive articles from said dispersion table;
a plurality of vibrator means for individually driving said feed troughs in an inclined linear reciprocating vibrating motion thereby advancing articles thereon toward the front end thereof;
a plurality of weighing means positioned under the front ends of said feed troughs and associated therewith, each weighing means including at least a weighing hopper and a weighing mechanism;
control circuit means coupled to said weighing means for calculating combinations of weights on the basis of values of weight of articles measured by said weighing means, wherein the sum weight of the combination of articles is equal to or closest within a preset range of allowance to a predetermined weight value, and for discharging articles in the weighing hoppers of the weighing means corresponding to the predetermined weight value; and
a chute for collecting articles discharged from said weighing hoppers and for dumping the articles outside the apparatus.
