| | Hello |
| [[File:transport_belt_preview.png|right]]
| | I am random guy from Czech republic and I found love with translating Factorio wiki to Czech language for people who don't speak English here. Feel free to fix my typos I hope i don't make many of them. |
| | |
| Pásový dopravníkový systém je první přepravní systém se kterým se [[player/cs|hráč]] setká. Spolu s [[Railway/cs|Vlaky]] a [[Logistic network/cs|Logistickými roboty]] tvoří hlavní transportní systémy Factoria.
| |
| | |
| Přepravní pásy jsou využívány k přepravě předmětů a fungují bez využití energie. Pásy dále dokážou interagovat s pohyblivými entitami jako s [[player/cs|hráčem]], [[vehicle/cs|vozidly]] a [[enemies/cs|nepřátely]], dále ovlivňují rychlost pohybu (zrychlují/zpomalují)
| |
| | |
| == Úrovně pásů ==
| |
| | |
| Factorio má 3 úrovně pásů (4 s [[Space Age/cs]]). [[transport belt/cs|Přepravní pás]] má žlutou barvu a je nejpomalejší a nejlevnější na výrobu. Další úrovní je {{TransLink|fast transport belt}} červené barvy a je 2x tak rychlý jako standardní přepravní pás. {{TransLink|express transport belt}} je finální úrovní v základní hře, jeho barva je modrá, je 3x rychlejší než standardní přepravní pás a 1,5x rychlejší než červený rychlí přepravní pás. {{TransLink|turbo transport belt}}{{SA}} lze vyrobit pouze na [[Vulcanus/cs|Vulcanusu]]. Jeho barva je zelená a je 4x rychlejší než standardní přepravní pás, 2x rychlejší než červený rychlí přepravní pás.
| |
| | |
| The "stacks" below refers to stacks created by a [[stack inserter]]{{SA}}, not inventory stacks. If no stack inserters are involved, this is equivalent to items.

| | |
| Regardless of the belt tier, a fully filled straight transport belt holds 8 stacks in total. For more information on this, see [[Transport belts/Physics]] and [https://factorio.com/blog/post/fff-276 Friday Facts #276 - Belt item spacing].

| == Belt mechanics ==
| |
| | |
| === Merging and un-merging belts ===
| |
| | |
| Belts of all tiers have 2 lanes for items to ride on. This allows for either a double flow of one material, or to transport two different materials on the same belt. Mixed belts can be beneficial for
| |
| smelting ore, or producing items with many different ingredients such as [[Utility science pack]]. The belt can be unmerged using a splitter filter. It is also possible to unmerge a mixed belt by using underground belts since an underground belt will block half of the belt.

| |
| | |
| Belts going across a splitter will have items from the splitter moving to one side of the crossing belt.
| |
| | |
| [[File:splitters_to_one_side.gif|center|Splitters moving objects to just one side of a belt.]]
| |
| | |
| Commonly, merging and un-merging is done by using a [[splitter]]. The trick in the second gif is better described in the '''[[Belt_transport_system#Separating_belt_lanes|underground belt]]''' section.
| |
| | |
| === Lane balance ===
| |
| | |
| Due to how items are placed onto belts by [[inserters]], their lanes can sometimes become unbalanced. In order to
| |
| maintain throughput, balancing the lanes may be necessary. The gifs below show two ways how to do this. The former only works if only one lane is in use initially. For further explanation of the mechanics, see [[Balancer mechanics#Lane_balancers|lane balancers]].

| |
| | |
| === Belt throughput ===
| |
| [[File:Stack inserters fill express belt.gif|frame|250px|right|4 [[bulk inserter]]s can compress an express belt at any stack size greater than or equal to 7 for the left inserters and stack size 7 for the right inserters.]]
| |
| Maximizing the throughput means ensuring that as many items as possible are transported. Therefore some definitions need to
| |
| be introduced:
| |
| | |
| ; Speed
| |
| : How fast a belt moves in tiles per second. This is 1.875, 3.75, 5.625 and 7.5 for basic, fast, express and turbo belts respectively.
| |
| ; Density
| |
| : How tight are the items put onto the belts; each straight belt piece can hold exactly 8 items.
| |
| ; Throughput
| |
| : This is speed × density. It describes how many items pass by at a given time.
| |
| | |
| So, there are three opportunities to enhance the throughput:
| |
| | |
| ; More density
| |
| :Sometimes items have small gaps in between each other that aren't big enough for other items to fit in. However, mining drills, inserters, and belt sideloading can still force an item into these gaps, temporarily squashing the items on the belt. The squashed gap is extended to normal size once the front of the belt starts to move again.
| |
| ; More speed
| |
| :If the belts in the factory are already at maximum density, their speed can still be upgraded with better belts. Finding the bottleneck is the first thing that needs to be done, usually it can be discovered quite easily. There will be a part of the belt where the items don't move quickly (or at all) or stop at maximum density and suddenly they come to a point where this 'stop and go' effect releases itself, the bottleneck has been found. In most cases, this will be the place where belt optimization is needed.
| |
| ; More belts
| |
| :Adding additional parallel belts can also increase the throughput. Simply place more belts carrying the item that needs throughput.
| |
| | |
| === Belt tricks ===
| |
| | |
| Moving fast can be essential to defend alien attacks in time. Running on a belt will increase or decrease the movement speed of the [[player]] accordingly to the belts speed. That is why building a belt towards your defenses can be beneficial.
| |
| | |
| However, the player is not the only unit that can be moved by transport belts. Additionally, biters and spitters can be moved. This can be abused to improve your defense. Firstly, biters will have a harder time to reach your walls when placing express transport belt in front of them. Secondly, spitters can be moved closer to your walls. That way more turrets can attack a single spitter at once.
| |
| | |
| Another useful usage is [[car]]s on transport belts. Cars have an inventory and can be filled by [[inserters]]. So, they can be used as moving boxes on belts. This has several advantages: Firstly the throughput of the belt-car-boxes is amazingly high, secondly the inserter stack size bonus does apply here and makes inserters more effective.
| |
| | |
| == Splitters ==
| |
| | |
| [[Splitters]] are another form of item manipulation. Splitters are a 2×1 entity that splits incoming items on belts
| |
| from up to two input to up to two outputs, in a 1:1 ratio. They are used to divide resources between two belts, or balance
| |
| multiple belts.
| |
| | |
| === Mechanics ===
| |
| | |
| The behavior of splitters looks simple at first glance. But they are not that simple. Splitters have an astonishing amount of uses.
| |
| | |
| * Splitters have two input belts and two output belts. If the splitter receives items on one belt, it will split the input evenly between its two outputs. If one of the outputs is fully backed-up and the splitter cannot split evenly, it will put all input on its other output.
| |
| * Splitters can also merge belts, taking two inputs and one output.
| |
| * Splitters preserve the lanes of the items, by moving through the splitter an item on the right lane will not be moved to the left lane, and vice versa.
| |
| * Splitters can prioritize one input and/or one output. Clicking on a splitter opens its GUI where the priorities can be set.
| |
| * One output of the splitter can be filtered to one item. Items of that type will only go to that output, and not to the other one.
| |
| | |
| The speed of the splitter is the same as its relevant type of belt, so in order to properly join/split belts, the splitter must be the same speed as the incoming belts. Otherwise the splitter will become a bottleneck.
| |
| | |
| ==== Priority ====
| |
| For both the input and output side of the splitter it is possible to set the priority to either left or right.
| |
| | |
| A splitter where the input priority has been set will first try to consume the specified input side, and will only
| |
| consume the other input once there is a gap on the prioritized input belt.
| |
| | |
| Similarly a splitter where the output priority has been set will try to redirect all incoming items
| |
| to the specified output, and will only output on the other output once the specified output is full.
| |
| | |
| ==== Filter ====
| |
| If a specific item is set in the splitter's filter slot, the slider for the output priority will
| |
| be used for the filter instead. All items of the set type will be redirected to that specific output
| |
| and all other items are directed to the other output. The input priority can be set independently of the filter.
| |
| | |
| === Balancing ===
| |
| | |
| {{Main|Balancer mechanics}}
| |
| | |
| Balancers are used to evenly distribute items over multiple belts or multiple belt lanes.

| == [[Circuit network]] ==
| |
| | |
| [[File:transport_belt_circuits.png|thumb|250px|Two belts connected to a [[constant combinator]].]]
| |
| [[Red wire|Red]] or [[green wire]]s can be connected to segments of transport belts to use them as part of a circuit. Belts connected to the circuit network will appear with a yellow cage above them, with a moving red scanner within it. When a belt is connected to a circuit, a GUI can be accessed from the connected belt for settings on how the belt will be used for a circuit; there are two modes of operation that can be used:
| |
| | |
| '''Enable/disable''' - A circuit condition dictates whether or not the belt will allow items through.<br />
| |
| '''Read belt contents''' - If enabled, the contents on the belt will be read.
| |
| | |
| The belt's GUI will also have a "content read mode" setting, which can be set to either '''pulse''' or '''hold'''. '''Pulse''' will read the belt's contents for only one [[Time|tick]], while '''hold''' will read the belt's contents continuously on every tick.

| | |
| == Underground belts ==
| |
| [[File:4-6-8.png|thumb|right|Underground lengths|250px]]
| |
| Underground belts can be used to cross different flows of items without interfering. They move items like a [[Transport belts|normal belt]].
| |
| * Underground belts can cross any number of entities and most types of ground, like water and grass, as long as the input and output endpoints are on land, except for space void and [[lava]]{{SA}}.
| |
| * Underground belts can cross other underground entities (any number of underground belts or underground pipes). They won't be mixed.
| |
| * For the connection only the endpoints (entry-side and exit-side) are relevant.
| |
| * The underground distance is 4, 6 and 8 [[Map_structure#Tile|tiles]], respectivly, for the three belt types in base game.
| |
| * An underground belt pair that bridges a gap of 4 tiles stores up to 44 items. An express underground belt pair at max length stores up to 72 items.
| |
| * The half of the underground belt tile with a belt can accept input from the side. The other half (with a tunnel entrance) blocks incoming items.
| |
| | |
| === Separating belt lanes ===
| |
| <gallery mode="nolines" class="center" widths=350px heights=350px>
| |
| File:Block belt lane.gif|This is built by placing one underground belt and then using R to reverse its direction. This converts the underground belt entrance to an exit (and vice versa).
| |
| File:Transport belts unmerge.gif|This can also be used to split the lanes of a belt onto seperate belts instead of using a splitter filter.
| |

| |
| | |
| === Braiding ===
| |
| <gallery mode="nolines" class="center" widths=450px heights=200px>
| |
| File:underground_belt_braiding.gif|Different types of underground belts can be braided together along the same line of tiles, with items staying in their respective belt types.
| |
| File:underground_belt_braiding2.gif|The same concept, but with a different belt design.
| |
| </gallery>
| |
| | |
| Braiding (sometimes called weaving) can be particularly useful where more than two input lanes are required while also avoiding the use of a parallel belt/[[long-handed inserter]] combination. For example, this can be useful if there is limited space, such as when using a beacon. With a beacon range of 3 orthogonal tiles, two of which would be occupied by a belt and inserter, it would not be possible to place the parallel belt in the third space and still have a beacon on the same side, as the assembler would now be in the fourth tile and not in range. With the space saved by braiding, this is now possible.
