This is the machine I am building to place turret lugs into the drilled turret boards
-
The automated lug sorter and feeder machine is about 2/3 done. It will deliver lugs to the grabber you see in the video It has to sort lugs into a horizontal line and then flip them up the correct way and then deliver it to the pick and place machine
-
got the BOM for that :icon_biggrin:
nicely done!
-
Way more fun than building an amp! :thumbsup:

> flip them up the correct way
A practical simplification, often used on vibratory feeders, is don't flip wrong-way parts, just reject them back to the supply bin. A knock-out may be cheaper and more reliable than a flipper. There's a 50% chance the part will come right the second time. It works about 75% of 'every time'. The cost (energy) to kick-back and feed again may be too small to care about.
Then I am thinking a Henry/Winchester repeating rifle. Tube feed. A lifter block takes a round from the tube, moves it to the chamber, and jams it in. A cam on a flywheel could probably stuff the turret *and* smack the backside to set it.

The feeder machine has 3 stages
Vibratory drum
Horizontal rail
lugs fall through gap and go upside down because they are top heavy
Next stage flips them right side up
Then they get delivered to the pick an place machine right side up
Stage one does this

Nice
Very Very COOL :thumbsup: :thumbsup: :thumbsup:

That's remarkable and superbly cool! You do some absolutely amazing stuff! Thanks for sharing. :thumbsup:

Ciao Doug
If I can permit me to suggest
When you finished the Pick & Place Machine plus the Feeding Machine
I think it will be useful you arrange your Pick & Place Machine Board "Bed" with an Under Plate (Bottom Plate) with installed a whole set of Pointy Tools (number corresponding to the max number of turret holes you can have in a board)
and
a Counter Board with a whole set of Hole Tools (number corresponding to the max number of turret holes you can have in a board) to be placed on the Top of the Pick & Place Machine Board "Bed" (and bloked in some way, like Threaded Rod that engases holes on the perifery of the Hole Tools Board or other way you think will perform better)
(https://el34world.com/charts/images/IMG_2366.jpg)
The Under Plate (Bottom Plate) will be moved UP (and down) with a small Hydraulic Piston (or perhaps Pneumatic Piston)
Something like this

Pneumatic

This way you'll be able to lock (block) all the Turrets present on the board at the same time
Alternatively, to avoid secondary problems (how to leave spikes marks on places where there are no turrets), may be you must mount on the Under Plate (Bottom Plate) only the Pointy Tools corresponding to the Turrets placed for the specific Board you are building
I hope I explained what I mean in a comprehnsible way

That would be a very different and separate machine
It has to do the same thing as my manual machine does
X & Y axis holds the board level and moves it over the tools
Two powerful motors bring the tools together to swage the lugs
-
X & Y axis holds the board level and moves it over the tools
Do you think it will worth the effort to implement a logic movement to press one turret at a time
instead to press it all together ?
I think that if the Under and Upper Boards holding the Point and Hole Tools are build enough strenght you can be quicker on your job and press all Turrets in one time
If you prefer you can build a stand alone unit to perform this job instead to integrate it on your Pick & Place Machine
Of course they are only ideas and must be compared with your experience and preferences of realization

Turret lugs have to go up inside the top tool
They are held firm at their basses, not their tops
They are soft brass, not steel
-
That is amazing! And here I am trying to figure out how to make a yard sale reloading press work better than my drill press for setting turrets. :worthy1:

out of curiosity, what pick and place application are you using? liteplacer or openpnp? custom?
