Coin Sorter

Initial Concept

The initial concept involved a design for the hopper and sorter.

Concept Hopper

A proof of concept design for the hopper. The feed is large enough for only one coin to pass through at a time. A divider is mounted above it to prevent jamming.

Concept Sorter

The orginal sorter, the holes are slightly larger than standard U.S. coins, with the dime being furthest right and quarter being furthest left.

First Sorter Version

The first design of the sorter considered for printing. Removed the unnecessary fillets around the coin holes and the excess material towards the back.

Sorter Final Version

Final version of the sorter. Removed more unneeded material and made the entry holes eliptical rather than circular. Tolerances were also increased.

First Hopper

The first hopper featured a large opening that fed into the chute with a flat plane.

Second Hopper Design

The second design replaced the flat plane with a curved surface to help reduce the chance of jamming during feeding. The final print removed the bottom chute entirely, leaving only the curved feeder.

Storage Construction

Completed Storage

Comleted storage with cardboard prototype of the sorter.

Sorter in Action

While testing a few issues were found:

Tolerances too high, pennies would often get stuck in the dime hole.
Improper angling, due to time constraints the correct angle for consitent sorting wasn't found.
