This “meta” design evolved into a much simpler piece of polycarb (or metal plate if you don’t have any polycarb) that pivots. Here’s an example below:

The polycarb is attached to a high strength shaft using HS pillow block bearings (since a low strength shaft would easily warp), and rubber bands hold it in a sort of “ramp” or flat position. The key here is to have the edge of the polycarb above the lip of the matchload tube, but low enough to slide under the lower slanted surface of a block (you can’t have it too high and hit the flat side of a block, or it’ll get stuck).
When the robot pushes into the matchload tube, the low polycarb slides underneath the lowest block, lifting the whole stack up. As the mechanism gets pushed further into the tube, the polycarb starts to follow the curve of the tube opening, slanting towards the robot. This creates a ramp that funnels the blocks into the intake.
