Could you have another belt going back the other way, and blow lego to hit a wall and drop on to it, instead of in a bin? Send it back towards the ramp, and find a mechanical or air powered way of getting the part over the plywood wall to be sent back round. That way you could just send a batch of 3-4 of the same part round repeatedly for a bit.
