Apparatus for counting articles using torque
First Claim
1. An apparatus for counting the number of articles comprisinga measuring chute rotatably journalled to a horizontal shaft at its one end and being arranged in an inclined fashion so that the articles can slide therealong downwards due to gravity;
- a device for electrically measuring torque generated around said horizontal shaft when the articles pass through the measuring chute to produce a torque output; and
a measuring circuit for receiving said torque output to count the number of articles by detecting a variation of the torque output due to the discharge of the respective articles from a lower end of the measuring chute remote from said horizontal shaft.

Abstract
An apparatus for counting the number of articles of the same kind comprising a measuring chute rotatably journalled to a horizontal shaft and being arranged in an inclined manner, a parts-feeder for supplying the articles onto the measuring chute substantially at a point of the horizontal shaft, a load detector for detecting torque generated on the horizontal shaft when the articles supplied on the measuring chute are discharged from the chute at its lower end remote from the horizontal shaft to produce a torque output and a measuring circuit including a circuit for detecting peaks in the torque output to produce pulses and a counter for counting the number of peaks.
