small rotating project?

Question

requirements:
3 balls. release each ball after 10sec always two of them at one exit, labbled A, and one B at a 2nd exit. Always repeating AABAAB...
anyone has good suggestions?

Answer 1

1.)
PLC controled feed escapment to pace feeding of balls at 10sec interval. AB Diverter chute with optic sensor to count and verify balls leaving feed escapment. Chute allows two counted balls to pass to A side then chute diverter gate switches to B side and allows one ball to pass.

2.)
Use verticle rotating wheel with three depressions to feed balls. (Think ferris wheel) the wheel rotates @ 1/2 rpm (30sec per rev) These equally spaced depressions will hold balls and the spacing and rpm will determine the feed rate.

The height of one of the three depressions will be different than the other two. This will allo one ball to be picked off the wheel at a different location than the other two which will be carried in a deeper depression. At the top of the wheel you have two pairs of rods at different elevations (A & B) The higher pair of rods will pick off the single B ball which will roll along the pair of rods to the B chute and the lower A rails will pick off the remaining A balls . The key to this feed system will be having a height difference in one of the three depressions and the height difference on the parallel rails used to remove the balls. The A balls ride lower and will miss the B rails.

3.)
If you are using the same three balls over and over you can have two slightly larger than the third and use the size difference to sort. Sorting may be done using a pair of rails which start out closly spaces and get wider apart. As the balls roll odown the rails the large balls will travel further along while the smaller "B" ball drops earlier. You can use a pair of escapments to hold back the B ball from rolling out the B chute untill two A balls pass.

Answer 2

I don't get it. You need to be a little more detailed in your question.
