COINER (Coin Sorting Machine - EURO version)

thingiverse

UPDATE 26.03.2017: I've added all Fusion 360 development files (f3d and step). Sorry for the messy organization. This is a remix and optimized version of acilias great coin sorting machine, modified to work with ALL Euro coins (1c, 2c, 5c, 10c, 20c, 50c, 1€, 2€). All parts have been modded and shouldn’t be combined with the parts of acilias machine. You can find the original design at http://www.thingiverse.com/thing:149839. SERVO MOD I used a standard size servo instead of gear motors to save money. Here's how to modify the servo: Desolder the wires from the potentiometer and motor, then resolder the power wire directly to the servo motor. Remove the notch that prevents over-rotation to get continuous spinning in one direction. You may need to adjust the voltage regulator to reduce the voltage to around 2.8V, which can vary depending on your servo. The connector.stl file might not fit your servo, so you'll need to DIY a solution or give me the necessary diameter and I'll create another version. FINE TUNING You'll need to fine-tune your printed parts, especially the coin slider, as every printer has different tolerances and filament properties. Fine-tuning means adjusting the hole diameter for the coins. If the coin doesn't fit, simply grind off a tiny bit of material with a Dremel tool. FILAMENT I used PETG filament from extrudr.eu for this project. PRINTER REQUIREMENTS You'll need a printer with a 20x20cm build volume to print this design. Check the print settings below. ADDITIONAL MODS (optional) Depending on your filament and its slipperiness properties, you may want to improve the slipperiness by using PTFE spray. The angle of the slide also plays a big role in making it work accurately. If you're experiencing sliding problems or coins getting stuck, try adjusting the angle slightly. The sweeps_complete.stl file was just a test; the latest design has straight sweeps that are sufficient and easier to print. COIN STOPPER You won't need the coin stopper for this version (at least for me, it raises the risk of a jam). PARTS YOU'LL NEED FOR THIS PROJECT * A few M3 screws (6-12mm) * Standard size servo * Voltage Regulator * Some kind of battery (+3V) * Rubber band (used to bind coin containers together for easier handling) * Euro coins VIDEOS You can watch the videos here: https://www.youtube.com/watch?v=qoul8Sco7UQ https://www.youtube.com/watch?v=XxiP9QvUS6Y Please post your printed machine and leave feedback on how it works for you. Thanks! Print Settings * Printer: i3 Prusa derivative * Rafts: No * Supports: No * Resolution: 0.2-0.3 * Infill: 0-100 * Notes: + HolePlate, Base, Sweeps: 0.3mm 20% infill + Rotor, Connector: 0.2mm 100% infill + Containers: 0.3mm, 0 Top Layers, 0% infill, 1 perimeter The containers should be printed with a thin wall; if your slicer has problems doing this, try vase mode or the Simplyfy 3D Hack "Merge all outlines into a single solid model" under the advanced tab. Only if these pieces are printed with 1 perimeter will they be stackable. Post-Printing See the fine-tune tips in the description.
