Question Upside down Frisbees; can your team get them out?

I was wondering how many teams can shoot out the flipped disks or if it happens are you stuck? If you can get them out how did your team do it?

We bent some plastic, attached it to our pusher and put double sided tape on the plastic so the tackiness of the tape will prevent the pusher from lifting the disk.

Why reject them when they're good discs?! We just shoot em. No difference to us.

Our shooter doesn't shoot them accurately, but it does eject them. They don't jam up our shooter at all, so if we accidentally pick them up- oh well!

Our shooter does better when the discs are upside-down: have to make sure our feeders remember to load them like that.

Re: Upside down Frisbees; can your team get them out?

We didn't think so, but according to our match videos it manages to pop them out eventually all by itself. As soon as we get it out of the bag we're going to try to figure how the heck that happens so we can do it on purpose if needed...

Re: Upside down Frisbees; can your team get them out?

1706 is able to flip them, or completely eject them, depending on how many frisbees are in our hopper. We have 2 pneumatic cylinders that eject it-see also spy movies-and it goes flying out.

We are able to flip them automatically from our harvester, no code needed, it's simply and very effective.

we spent a lot of time making sure our discs don't flip upside down when feeding. On the rare chance we get an upside down disc, we added a 2nd pneumatic trigger with a larger profile to flick out the upside down disc.

Re: Upside down Frisbees; can your team get them out?

Same, with us upside down shoots better mostly since it grips more on the shooterwheels.

We-re able to shoot upsidedown frisbees b/c of our cam design(We actually planned it for just in case)

Re: Upside down Frisbees; can your team get them out?

Took us a while, but we added a cut-down clevis to the end of our pneumatic chambering cylinder, so upside-down discs come out well enough, but only at low-goal height. It's a nice KISS solution and I hope it works for others with the same problem. Most of the time it's not worth it to us to score them in the Low Goal though, so we just eject and move on.

Re: Upside down Frisbees; can your team get them out?

We have a trap door in the bottom door of the shooter bucket that we can release when we have an upside down disk. An unintended consequence of abandoning floor pickup is that we can use the elevator chute for ejection.

Re: Upside down Frisbees; can your team get them out?

We had a lot of trouble with that our first district and a half. Halfway through Detroit though we added a clear plastic (lexan?) sheet in between our hangers to help block cross-courters, and we found that it extended down in such a way that unless our loader intentionally fed them upside down, it was almost impossible for them to flip. Worked wonders for the rest of the competition!
