Coinsort Challenge

My Coinsorter slide was also Laser printed(no picture). AutoCAD was used to design both my trapezoidal bases and slide for the coins. Once the designs were made on AutoCAD, the file was put onto a USB thumb drive and that file is read by the laser printer.

This is both Subsystem 1 and 2 combined. Subsystem 2 as shown is the slide with 3D cut holes to match coin size. I had a total of 7 redesigns on this part to get it working accurately. I had to make the First hole smaller because pennies were fitting into it and, I had to make the 3 hole bumper so that the quarter would not slide through it. Both of these redesigns took about three tries. Would have been much easier if I was able to use the Laser printer in class, but I didn't have enough time.

Both of these are the coin-sorting accuracy data sheets. Five redesigns were done in order to get a design that was almost 100 percent accurate. The fifth design went through three tests each test had four of each of the four kinds of coins( 16 coins in total.) That means 48 coins were tested. This design was 91 percent accurate. The difference the project needed was a firmer material for the slide. Some of the students were using plastic. That plastic would have worked great for my slide and most definitely would have given 100 percent accuracy.

These are some close-up shots of my funnel system. When the coins fall down the holes, they drop into the coin hole's respective funnel. The funnel leads the coin into my last subsystem which is where the coins can be seen and retrieved after they have been sorted.

This is the final part of the coin sorter. The coins will fall into their respective boxes. Each box has a unique hinged door that opens and allows for easy retrieval of the now-sorted coins.
