This thing may be old and ugly and rusty but when I had my business a few years ago I designed and built this prototype chip cleaner. Not only did it work but it worked surprisingly well. I never really finished it since the back section was supposed to be used for drying the chips. They were fed into the stack on the left hand side. The air cylinder pulled one chip from the stack, rotated it 90 degrees and it fell down the chute to the cleaning station. There 2 brushes, mounted on air cylinders, stroked up and down to clean the chip. After it was clean another cylinder raised the chip up to another track where it rolled halfway down to be stopped by another cylinder at the drying station. After drying, the cylinder released the chip and it rolled out of the machine into a bucket to be taken away. The advantage of this machine over some existing models is that it needed no electricity except to run a very small air compresor. The whole machine was controlled by air logic and could clean and dry a chip about every 15 seconds. The best part is that it could be operated by casino personnel not an outside company who charged by the chip for cleaning. Of course the finished model would have been made out of machined stainless steel (not saw cut regular steel; crudely welded)with the cylinders hidden, etc.

Neat huh???
