Vibration bowl

thingiverse

A vibration bowl is an effective tool for sorting and separating small items. Watch this YouTube video for a demonstration (http://www.youtube.com/watch?v=BY2Byhj0xbY). The design should not exceed a 45-degree overhang, which is necessary for printing. This creation is part of the Ultimaker Challenge to aid in kit assembly. It has some parametric features. However, note that this was designed by someone with no experience in vibration bowls or 3D printing and is unsure if PLA or ABS will hold together during vibration. To assemble, print at the correct scale, attach the motor to the excenter beneath the cone using glue, and position it loosely on springs or rubber bands. Install a counting photocell near the exit and use a servo to stop the feed from falling out when the desired quantity is reached. Pour screws (or nuts) into the bowl. Watch as the vibration moves them up the ramp, aligning and separating them. Add extra 'chicanes' if necessary to reject improperly oriented or stacked screws.
