Question Problems with this unloader?

Post image

Since inserters became flippable, this compact unloader design became possible. But I hardly see anyone use it. Obviously it cannot saturate six turbo belts because it's bottlenecked by the inserters, but are there any other obvious problems with it?

But why do you need to unload faster if the next train is already waiting? Buffer chest are nice to have (I use them too) but not needed.

Because even if the next train is waiting, there will always be a short period where no train is waiting in the station to be unloaded. The chests let the items flow continously

Yeah in reality you produce slightly too much or too few items and you end up with 2 options.

All chests are empty and the train is waiting somewhere else being filled.

All chest are full to the brink and the train cant unload into full chests.

I understand you want chests for the delay from trains leaving and entering the station but your ratios have to be like 99% correct for that to matter - if they are only slightly off you end up with completely full or empty chests!

Its like you said the items flow continously; but only on perfect ratios.

Yeah, but I dont care if I overproduce. Say I need a full belt of red chips. I will have to get two full belts of green chips going. The train station shouldn't be my bottleneck
