Set the combinator to take Each (yellow star) and divide by the negative number of chests.Goal: Load n chests with approximately the same number of items. This will prevent fluid system deadlocks where you have plenty of one fluid but you are unable to make any of the other. set "heavy oil > light oil" for the heavy oil cracking input pump, set "heavy oil > lubricant" for the lubricant production input pump, and set "light oil > petroleum gas" for the light oil cracking input pump.ĭone! Now all the pumps will move to equalize the fluid levels to each other. For each connected pump set the circuit “enable condition” to " > ", for its respective chemical plant recipe.The resulting circuit network will know about the fluid level in every storage tank and pass this information to every pump. Connect every pump and every fluid tank to a single circuit network of red (or green) wire.

Note: Alternatively, the blocking pumps could be added to the chemical plant output pipes, but there is no need to add pumps to both inputs and outputs. For each chemical plant (or each row of them, if you use rows) add a pump to the non-water fluid input pipe to make it possible to block the flow.For each fluid, make sure to connect the tank via pipes to every location where the fluid is being produced or consumed. Have a fluid tank for heavy oil, light oil, petroleum gas, and lubricant.To see the settings of combinators without opening them, the option "Show combinator settings in "Alt-mode"" in the Interface/Alt-mode settings has to be checked and "Alt-mode" has to be turned on. They are designed to be as easy to understand as possible. This page provides examples of simple circuit network designs and some not so simple designs that others can use, combine and modify. 7.3 Prioritize usage of uranium towards nuclear fuel production.7.2 Optimal usage of fuel for nuclear power.5.4 Balanced Solar panel / Accumulator Production.5.3 Keeping outpost stocked with specified items.4.4 Constant Combinator Signs (Managing Belts).3.3 Alternative Setup for Cracking and Lubricant Production.2.1 Lamp showing chest content condition.At that point this set up should give you near perfect equilibrium and before you reach that state it should still be relatively balanced due to the inserters unloading the cars at nearly the same speed.
Factorio unloading station full#
That is of course taking into consideration that you will have to saturate the total number of chests used for storage to x- one full train load. It will eventually balance to almost perfect equilibrium until all the wagons are completely empty at which time the train will leave the station. When you pull up, the stack inserters will move things into the chests quickly while the rest of the material starts playing ring around the rosey. Just make a circular belt loop with standard (yellow) belts that runs the entire length of the train and use 3 standard inserters on one end of the wagon to unload on to the belt and 3 long inserters to take off the other side of the belt and put back in the wagon. You could even use the set up on a train with more than 2 cargo wagons. If it isn't perfectly balanced at that time it will only be off by a tiny bit and that situation will only last until the next train arrives. Once all of the chests on that side are full no more material can go off that rail car in that direction which means the material's only option for motion is the circular loop on the other side where it will happily spin around from one car to the other until the entire train is empty.Īs long as you set the train's condition at the stop to empty cargo it should stay at the stop until the very last bit of material is in one of the chests, in an inserter's hand, or on the circular belt. I usually just brute-force things with trains and balance their contents using belt balancers.ĭo you even need all the wires? Once one of the chests is full the associated stack inserter will stop moving. Since it's not unloading onto belts and the chests aren't logistics chests, they're there purely for you to pick up on the go, and you should never need to pick up a wagon's load of coal, let alone 18 steel chests worth.Īs to the circuit question, sorry I can't contribute. It seems simple enough if one wagon fails to unload because the chests are empty to then move the remaining contents of the wagon to the other this is just a mock-up, though, I don't quite see the point. The OP already has the infrastructure for unloading from each wagon. It would be simpler to control how those chests unload unto the distribution belts and better balancing of the belts from the chests to consumers could be enough.
