# Conveyor Belt Barcode Scanning System

- Feb 05, 2019-

The conveyor system is the first system that the player can access to transport items from one place to another. Together with the railway and the logistics network, it forms the logistics system of the alien factory.

Conveyor belts are specifically designed to transport items that do not consume energy. Conveyor belts can also interact with other objects such as players, vehicles, and bugs to increase or slow down movement.

Conveyor belt carrying flow

The four robotic arms can be used to cover this extremely fast conveyor belt, with two of the two robotic arms on the left side placed at one time and seven on the right side.

For efficiency, it is important to keep your traffic flowing. So you need to understand some concepts:

speed

How fast the conveyor moves.

density

The tightness of the placement of the item on the conveyor belt.

flow

Speed × Density describes how many items are available within a specified time.

Therefore, there are three possible ways to increase the carrying traffic:

Greater density

Sometimes there is a gap between the two objects on the conveyor belt, but it is not large enough to hold a complete item. However, the intersection of the mining machine, the robotic arm, and the conveyor belt can still force an item into the gap, temporarily squeezing the items on the conveyor belt, and returning the space to the normal size when the item in front begins to move.

Higher speed

If the conveyor belt in the factory has reached the maximum density, you can upgrade to a higher speed. The first thing to do is to find the bottleneck. Generally speaking, it is not difficult to find that there will always be a local item on the conveyor belt that moves slowly on it (or does not move), or like a traffic jam, walk for a while. One paragraph. Once found, this is usually where the conveyor efficiency needs to be rectified and optimized.

More conveyor belts

Parallel construction of additional conveyor belts can achieve the purpose of increasing the flow. If you want to increase the flow of an item, you only need to place more conveyor belts to transport the item, but don't forget to use a balanced distributor to evenly distribute the load.

Conveyor tips

Sometimes in order to deal with alien attacks, fast moving is very important. Running on a conveyor belt will increase or decrease the player's movement speed depending on their level, so it may be important to build a conveyor belt that faces your defense.

However, the player is not the only individual who can move on the conveyor belt, and the alien worms can also be moved by the conveyor belt, which can be used to play with the bugs. First, the speed belt can be placed outwards in front of the wall so that it cannot easily touch the wall. Secondly, the conveyor can be transported inward, so that more turrets can simultaneously greet a bug.

Another useful method is to place the car on a conveyor belt. The car has an item bar, so it can be loaded and unloaded with a robotic arm. With this, the car can be used as a box on the conveyor belt. The advantage of this is that: first of all, the "box" has a high throughput capacity, and the second assembly arm can load and unload a group of items at one time without waiting for the conveyor belt to spread out slowly.

Splitter

The shunt is another form of manipulating items. They occupy 2x1 grids and divide the items on the conveyor belt into two or two in one-to-one ratio. They are generally used to distribute items to two. On the conveyor belt, or to balance multiple conveyor belts.

Principle mechanism

At first glance, the mechanism of the shunt may be simple, but the shunt is definitely not as weak as you think, and its utilization is actually terrible.

The splitter has two conveyor input ports and two output ports. If one of the input ports receives the incoming item, it will evenly distribute the incoming items to the two output ports.

If one of the outlets is full and cannot be evenly distributed, it will output all the inputs to another outlet that is not full.

The shunt can also accept two port inputs and one port output.

The shunt does not change the state of the conveyor line, the items on the right line do not go to the left line, and vice versa.

The shunt can preferentially input/output items on one side, and click the shunt to open the setting interface for setting.

One of the two output ports of the splitter can be set to filter an item. This type of item will only be output from this port, and will not take another one. The exit of this side of the filter item will be output first.

When merging/separating the conveyor, the level of the splitter must be the same as the speed of the incoming conveyor, otherwise the splitter will become the bottleneck.
