Every now and then, I goof around with my home made cent sorters. I've got a couple of ideas on how to make dramatic improvements to the process of sorting cladded Zn from Cu-alloy cents and one of these days, I'ma gonna do it. In the mean time, I tweak the sorters I've made.
Last night, I decided that I was going to run my latest sorter as close to the theoretical maximum as possible (the comparator is capable of 8 coins per second). The hopper motor is rated for 24VDC, but should tolerate 30V-32V for reasonable durations if the torque load is reasonable. That is where I was running it, just over 30V.
In any event, I was seeing rates of 7 to 7.5 coins sorted per second and was able to sort a $50 bag in just over 15min. It would have been about 13min if not for 4 jams/clogs.
Videos are linked rather than embedded. You'll probably see enough by just watching the first and last one, but I included all of them because it shows the total elapsed time of sorting. Each video ends with a clog and I spend about 20 seconds clearing the clog before starting the next video. For the video that doesn't end in a clog, I had to "stir" the hopper with a screwdriver because when the level of coins gets very low, the hopper agitator doesn't stir them anymore. I stopped the video to do the stirring.
You'll see that the end count is greater than 5000 coins. That is because the coins that clog get counted and when I clear the clog, I throw those back in the hopper for sorting. That results in a double count of those coins.
