| I buy mostly used Lego lots and sort constantly (by hand) so something like this
would be helpful. I have seen several of this type of sorter online in the past
and wondered if square sorter slots would be better than the round. Of course
I have not way to check...
If I had one of these available I would certainly try it, at the very least to
get all the small things sorted from the very large. Maybe a new business venture
for someone crafty?

| I’ve also seen it several times. I have sorted (with some help from family) over
1200lbs of bulk used. I was at first interested in one of these but then after
thinking about it for a while I deciders against it as I thought would it actually
help since what if a brick is horizontal instead of verticals or the opposite
then it would likely go in the wrong spot (very bad explanation but I hope the
point gets across) however I could see if some padding was added then something
like this would be extremely useful for sorting bulk new sets where there are
only a limited number of bricks so it’s unlikely that large quantities of incorrect
items would get mixed in.

I initially thought “what a great idea!” to then quickly wonder if it’s a very
useful one. We’ve only ever sorted Lego from new set part-outs, and in that regard
I can’t see it’s usefulness. Though I do appreciate the build and design.
Those of you that sort Lego in bulk, would you find it useful? Is it something
you’d use in your business or hobby?
Just curious

All of these lego sorters always look like the dumbest thing in the world to
me.

They don't do a very good job at sorting, but not bad at pre sorting by size.
Of course there is still the job of sorting everything by hand. Presumably pre
sorting like this does mean there will be a narrower range of parts in each batch,
so less pots needed when doing the manual sort.

Even for pre-sorting I'm really sceptical - I expect you will always have
overlap between the segments of parts that "kind of" fit through the holes, and
only part of them made it through. Which means all segments end up overlapping
each other, and that kind of defeats the point of presorting as far as I can
see.

If you have set up for example 100 sorting bins for a batch and the wrong size
parts have got in, presumably you just chuck them back into the bucket to be
sorted again (or chuck them in the correct tray if it is obvious). I've seen
a few videos like this and they do a crude sort but won't be replacing human
intelligence or speed in the near future.

I'm leaning more towards and AI sorter when I get around to it. Everything
makes sense to me but I want something that can handle more output buckets so
I can just dump the Ninjago City Gardens set in to it and have it all sort.
There are other versions of this out there that use multi level output conveyors
with dual directional push arms.

It wouldn't be a good idea to use this to part out a new set. All the shaking
to sort would leave the parts rather scratched.

Having experimented with vibratory feeders, I would say that that the shaking
part is not what causes the scratches. The plastic is hard enough and the parts
light enough to handle that light "jumping" action very nicely.
What causes far more damage, is the conveyor step. When you load a couple of
kg of parts in the hopper so the machine can run for a couple of hours unattended,
the conveyor pulls parts from the bottom and drags them under a couple of kg
of weight. That's where they tend to scratch. A shallow incline hopper reduces
that weight but increases the footprint of the machine.
A machine that can sort every part type in a separate bucket is highly impractical
in my experience. I built a model with just over 250 classes which covers most
of the sub-2x2 parts. 250 buckets is completely impractical so the sort can't
be done in a single go. The parts have to go through the machine a number of
times.
The distribution of parts in 5kg of small parts is such that from those 250 classes,
most end up with 20 or fewer pieces. Combine that with a model accuracy of around
90-95% and you would be better off sorting by had.
My next round of tests, when I get the time and energy, will be with "category"
sorting. Bricks, plates, tiles, clips, pins etc etc and do the final sorting
by hand. First I need to re-think the mechanical part of it though. Part separation
is far trickier than it seems and it's crucial to increasing accuracy.
Oh, and don't forget noise! No matter what I've tried, the blooming thing
is loud! Conveyors, vibrators, servos and parts clicking around all over the
place makes it unbearable to sit in the same room with for any reasonable amount
of time (hence the need for a large hopper).

That machine is actually very gentle on the bricks compared to what they go through
during a Lego production run (skip to around 1:50 mark):-
