Automatic Feeder Control (AFC) automatically changes the amplitude and/or time of the linear feeders up and down to account for product flow changes caused by either processing changes or product buildup on the linear feed pans. It’s important that the automatic adjustment is made both up and down to keep the average number of buckets used in a combination in the proper range which ensures the most accurate and efficient operation possible.
Yamato’s 3 Types of Automatic Feeder Control (AFC):
AFC – Total uses a settable and programmable target number of weigh buckets per discharge. If the average goes out of the programmable window then the AFC automatically adjusts the amplitude of the feeders up or down to bring the average back into the proper range.
AFC – Individual monitors the average weight in each bucket and compares it to a settable and programmable individual target (typically 25% of the total target weight). If the weight in an individual bucket goes out of the programmable window then the AFC automatically adjusts the amplitude of the individual feeder up or down to bring the average back into the proper range.
AFC – Random automatically generates “random” variability in the amount of product in each bucket. It is useful in those cases where product feed and/ or piece weight is so uniform that it can cause inefficiency due to scale recombination cycles.
