I want to create a filling machine for powders (different powders).
My idea was to do the following:
-Having a rotating plate with containers through it.
-rotating plate rotates the right container over a funnel.
-Some sort of valve opens, product starts falling in funnel.
-Product falls through the tunnel in a jar that is on a scale.
-When the right amount is reached, valve closes itself.
-The rotating plate of the jars rotates to next jar.
-Rotating plate of the upper containers rotates to desired product.
-Desired products + amounts are read from an sdcard or something, like:
Product1, 50 grams
Product3, 78 grams
Product7, 32 grams
Product2, 12 grams
I try to draw a picture about what I want to make, see attachment.
I think the rotating plates and the scale are no problem, but I have no idea about a valve. Maybe a valve that slides a whole open and close would be better. But I have no idea if something like that exists.
Problem is that I need a valve for every container in the upper rotating plate.
Any ideas, suggestions or critics?
