First post here. Looking forward to what I find here. I've always enjoyed fabricating and what not. So my dad opened a distillery and I went down to help out with bottling last week. It's an assembly line for sure. Each person has one job and you just pass the bottle to the next guy. Well whoever puts the cork in does it with his hand and after an hour of that your palm gets sore so I figure I can fix that. I've got a way to get the cork in, now I just need a hopper/sorter/orienter so the cork arrives ready to be pushed the right way. Here's what I got so far; imagine a vibrating aluminum cylinder. The bottom is a cone where the center is barely higher than the outside edge so that the corks make there way to the wall. The inside of the wall has a ramp that wraps around and around and gradually gets skinnier near the top so that the corks fall off unless they are oriented the right way. Then they would exit the hopper and enter a slide rail that delivers the cork to the capper. The corks that aren't sitting the right way fall back to the bottom and start over. So how do I get the vibrations to make the corks climb? Is there a certain frequency I need to look for or what? I have no engineering education so if this is something simple then I apologize in advance.
