Coin Sorting Project

As one of our design projects, I designed and created a coin sorter. I also modeled it into wall studs so that it could be a practical home appliance that does not take up unnecessary space. The idea is that it takes quarters, dimes, nickels, and pennies through the funnel and they roll down the track. There is a plexiglass cover so that you can see the mechanism as it works. The coins then sort into the bottom part where the coin holders are measured to hold the perfect amount of coins to fit in a coin roll. For example, the quarter roll holds 40 quarters, the dime roll holds 50 dimes, etc.

Parts

The track pulls out so the the coin rolls are able to be removed. The lip on the top of the coin rolls makes it so that if there are more coins than in the roll, they stay on that lip until the rolls are pushed back on the track under the sorter. This makes it easy to use and create rolls of coins to send to the bank.

3D PRINT & MODEL

This piece is adjustable so that it can fit in between any studs with 1 inch of tolerance on each side. It has holes getting bigger for the coin as it rolls down. Only dimes are small enough to fall through the first, only nickels through the second, etc.

The frame was created for aesthetic reasons so that you are not able to see the wall studs and it it is able to be installed in 1 piece.

The funnel took 6 failed prototypes to get right. We started off with a big funnel, but not only did it not fit into the wall stud, the coins got stuck at the bottom of the funnel.

This piece has the perfect angle to hold the coin rolls so they roll down the track without getting caught by too much friction on the walls. They also have holes so they can screw into the wall studs.
