초록

An improved feeder control system is disclosed. The system implements an incremental metering process that incorporates the standard deviation of the material feeder. By intentionally initially under metering at a level corresponding the standard deviation of the feeder, and then subsequently metering a more accurate delivery of materials is achieved. Additionally, the system implements a system for correcting for metering errors caused by gate cycles delays. By incorporating offsets into a feed time when gate cycle time is larger than the feed time, err...

청구항

1. A method for controlling the cyclical feeding of material through a feeder comprising the steps of:(a) calculating a target feed amount for a flowable, bulk solid ingredient material;(b) emptying a hopper;(c) calculating an adjusted feed amount substantially equivalent to a percentage of said target feed amount;(d) calculating a feed time to feed said adjusted feed amount of said material through a feeder to said hopper;(e) recalculating said feed time to include a feeder cycle offset;(f) feeding said feeder for said feed time;(g) generating a weight ...
