Here
in the US we like to add the suffix “ware” to everything. This
probably stems from the perception that software is cool, and it
means we now have silverware (knives and forks,) flatware (plates)
and stemware (wine glasses.) That last group is of course a subset of
glassware, or what you and I might call “glasses” while all the
above can be lumped under the heading of “tableware”. All this
ware has to be manufactured some-where, (sorry, I couldn’t resist
it,) and where (there I go again,) there’s manufacturing there’s
also inspection.
Today
I want to share details of an inspection system for glasses. This
comes courtesy of Allied Vision Technologies, who supplied the
cameras for the O2KS “Cold-end
tableware” inspection system.
As
is my habit, I’m not going to steal page clicks from AVT, so click
the link above to learn more. In particular, note how the machine
developer/builder, E3tam of Turkey, configured lighting and optics to
image four 90o
segments of the cylindrical surface. Also note that they went with
what I consider relatively low-resolution cameras but made use of
telecentric lenses. In short, some interesting design decisions.
Also
interesting is that the software is LabVIEW-based. My love of LabVIEW
is no secret, but it’s not often one sees it used in commercial
inspection systems, and especially not one from Europe. In my
experience Europeans tend to go with products like Halcon or CVB for
their machine vision.
Regular
readers might recall that I’ve posted about similar systems in the
past. “US-built
bottle inspection systems”
will take you to the most recent of these, and they seem pretty
similar. Did E3tam’s client consider buying a modified bottle
inspector? I guess we’ll never know.
And
in wrapping up, let me quickly share a link to the builder:

will let you learn more about them and their capabilities.
