Bucket Indexer tips

Heyoh All-

Today was quite an experiance for the team, we've got a bucket indexer/hopper on the back end of our arm where all the frisbees stack then get pushed via pneumatics into our shooter. We had rediculous problems with jamming all day and it isn't looking too good. We were just wondering if anyone else with bucket indexers would like to toss some tips around.

Specific issues were having:
The frisbees seem to enter the bucket alright - usually. sometimes they enter at a weird angle I guess from our conveyor and don't really enter it right until the next frisbee comes in. Probably nothing you guys can help with on this without seeing the specific setup but worth a shot.

When the frisbees do stack, we have an issue where sometimes the frisbee above the bottom frisbee will not sit right, because the bottom frisbee will be slightly leaving the bucket causing our pusher to push the frisbee above the bottom frisbee into the bucket wall instead of pushing the bottom frisbee into the shooter. (because the 2nd frisbee will be leaning at a slight angle from not sitting directly on top of the bottom frisbee)

Overall shape of the bucket, we actually switched to curved sheet metal and we were bucketwrangling with this all day. Everytime we fix one issue an old one pops up, then we fix that and the other issue pops back up.

So yeah, just looking for some general bucket tips. Pitch in anything ya got.
