WEIGHT FEEDER SYSTEM |
摘要 |
The automatically controlled weight feeding appts. includes a container prefitted with a substance and a device for discharging the substance at a controllable rate. The container and its contents are weighed to produce an amplified signal proportional to the weight. An A-D converter is coupled to a digital computer determining the weight of substance remaining in the container. A second amplifier is coupled to the first amplifier and a ramp off-set circuit controlled by the digital computer inputs a second signal to the second amplifier. The amplifier has a controlled stepping output applied as a second input signal to the second amplifier to maintain the output of the second amplifier within a given selected range of amplitude. The computer produces a corrective signal for controlling the discharge of material. |
