Offload station sorting with splitters, not robots

Post by vorner »

Hello

When importing resources from mining outposts, I've started with having one station for each separate resource. But I didn't like it and was thinking how to be able to be able to offload any train with resources, even possibly mixed up (I tend to aggregate products of multiple outposts together into a larger train, if they are far away) and sort them out. When going through the Internet, the usual solution seem to be robots, which felt wrong ‒ they tend to eat a lot of power, swarm around in a chaotic way, need to recharge all the time and sometimes decide to carry something far away.

So I've decided to build the sorting logic with blue belts and splitters. This is something like third generation of the design, and I'm starting to feel happy about it.
  • It is extensible for how many resources you like (I bring both raw resources and some already processed, like copper plates or green circuits).
  • It can process full 8 blue belts of input as long as the outputs are able to swallow them. If some of the outputs slows down or blocks, it unfortunately blocks the rest of the thing.
  • Each resource has its stockpile buffer. Current setup is able to pass through 2 full belts and store 4 belts in addition to that (therefore swallowing 6 belts of throughput) or provide 2 belts of output when no resources are coming from the trains at the moment. I connect only one output for my factory, because it's enough for me, with the exception of copper plates.
  • While the sorter itself works without any circuitry (and with minimal power consumption), something needs to make sure the buffers are not overfilled (otherwise it would block all the other resources) ‒ maybe allowing the trains in selectively by a condition (a stop with circuit condition for the train to leave with crates + train - configured constants <= 0) before the main station, or (what I do) order the train from the outpost only when it would fit. This is why the blueprint contains green wire connecting all the crates in the buffer (beware, left and right buffer is not connected, it expects to be connected somewhere at the top/bottom). But I think you need some kind of input limiting even in case of robots, or one kind of resource would fill up all the storage and wouldn't let anything else in.
The blueprint is for one resource only ‒ multiple need to be placed in a row and the splitters configured for the right resource (the copy configuration thing, eg shift+right mouse, shift + left mouse works on splitters).

By the way, the full chests are a bit pain in the ass to move around even with robots, rebuilding this for better design is problematic ‒ especially if you want to keep the downtime of supplies as short as possible.
