Scanning for Ideas: Sorting 900 Parts/Hour
The ShadowGage noncontact sorting machine from
Resec Systems Inc., Bergenfield, N.J. (
resecsystems.com), can sort up to 900 parts/hr, doing a 360° scan on all parts.
It checks up to 30
critical dimensions and can ensure they
are within 0.0002 in. of their specified
tolerances. The device can handle parts
up to 1.75 in. long and 1 in. in diameter.
In operation, parts are loaded via
a vibratory feeder or gravity track. A
screw-driven rod pushes them, one at
a time, onto the unit’s rotary stage. The
stage revolves through 360° in front of a
camera lens optimized to take silhouettes
of the part at various angles. The unit
measures various dimensions such as
diameters, lengths, angles, and radii,
virtually anything that casts a shadow.
Users can determine tolerances for each
part. And all inspection data can be saved
to a computer file.
