Fabrication cad | fabrication This is just a note to see how this works more than anything else. I have recently changed my full-time job, and am working LOTS of hours to keep up with a company that is very behind. Hopefully we will catch up sometime and things will slow down. Been working lately on a set of wheels to feed a premeasured lot of angel hair pasta down about 12 inches to a conveyor bucket. Our wheels are moving at 50rpm, and each wheel fills 2 buckets per revolution. The conveyor is moving about 200 buckets per minute and the buckets are 10 inches apart. We are doing this with 2 wheels spaced at 50" apart so that every other bucket is filled by the other wheel. (am I making sense here?) Having a time finding out how to keep the pasta in the cups on the wheel, while it turns over to dump into the conveyor bucket. First we thought of putting a tight "keeper" on the face of the wheel. That sounded like a problem as the pasta is so fine, and we would practically need to have a face to face fit. My boss came up with an idea to put teeth on the face of the cups in the wheel. Then we put a keeper made out of delrin with grooves for the teeth to ride in. We can have a 1/16 inch gap all around and still not let anything fall out. The edge of the cup turned out to look like this (kinda-sorta) and the cuts in the delrin looked similar, but with wider cuts for clearance. ---- ---- ---- ---- ---- (oh well, the ascii art didn't turn out.) If anyone else has something cool they are working on, let's hear about it! pictures

It may take a while, but I will try to get some pictures (at least 1 or 2) and post them. I thought this was a really neat idea. I just wish I could describe it better. Rick Crawford at Smoky Forge » reply pics of fabrication stuff

OK, I finally got the pics of the wheel and the keeper. These are all the pics I could get. The one is of the wheel to hold the pasta as it goes from the hopper to the conveyor. It is made of #10 ga (0.135) t-304 S.S. sheet, cut and welded. Then bead blasted. The other is a keeper to be mounted sideways on one side of the wheel. Made from a block of UHMW plastic 6-1/2" x 10" x 4" thick. This will keep the pasta from falling out as the wheel turns. With the tabs sticking out from the cups on the wheel, and the grooves cut into the keeper, they will never need to contact each other and will still keep the 4-1/2 inch long strings of angel hair pasta in the cup as it turns.
Well, my pictures didn't come thru. Not sure why. Too large, maybe? had a glitch as I was loading them in that the box said there was a problem when it got done, but I thought that they were done before that came up, so I didn't write it down to remember it. Will try again after a re-boot.

I was wondering where you've
I was wondering where you've been. Glad to hear you are busy with your metalworking skills and making lots of money.
I don't quite understand what you are doing even though your ascii art is neet... looks kinda like a railroad track. Maybe you could sneak in a camera to work and take a couple of pics to upload so we can see what you're doing.
Good to hear from you Rick!
