Perfect Train Unloaders

Anonymous

Shows how to unload a train car to 3 perfect blue belts using inserters. The unloaders with the underground belts can clearly be stacked 3 times carriage. In the experimental setup, the != and + circuits count and buffer every tick the belt is not perfectly full. Once the setups stabilise (fill the carriage with enough something to keep it going), you can run it indefinitely and it won't glitch. Two orientations work naturally, two need a little bit of circuit help. This is because the timing of unloading on to an innie underground belt is different in two orientations. For the ones that aren't perfect out of the box, the - combinator phases the enable of the inserter to cost it 1 tick per cycle to make the timing work.
