The basic principle of assembly line is to decompose a repeated production process into several sub processes. The former sub process creates execution conditions for the next sub process, and each process can be carried out simultaneously with other sub processes. In short, it is “functional decomposition, sequential in space, overlapping and parallel in time”.
The characteristic of production line is that each process is completed by a specific person step by step. Each person does a specific work。
The advantage is that it will produce faster, because everyone only needs to do one thing and is very familiar with what they do.
The disadvantage is that people who work will feel very boring.
The types of production lines are divided into product production lines and parts production lines according to the scope, flow production lines and non flow production lines according to the pace, and automatic production lines and non automatic production lines according to the degree of automation.
Assembly line plays an important role in industrial production. Optimizing assembly line is directly related to product quality and production efficiency, so it has become a topic that enterprises have to pay attention to.
- Optimize the operation time of the first station of the assembly line and how often to put a board, which is the investment time necessary to meet the production plan. However, in fact, the operation time of the bottleneck station must be greater than that of the first station. The first station must not be the bottleneck station, so the first station of the assembly line may not be invested completely according to the required time, because the bottleneck station has slowed down its speed, so from the perspective of management, the operator of the first station should be required to invest at the specified speed.
- Observe which station on the assembly line is the bottleneck station:
(1) Always busy station;
(2) A station that always pulls the board back;
(3) Starting from the station, there was a gap between the boards one after another.
3. Observe which station on the assembly line is the bottleneck station:
(1) Always busy station;
(2) A station that always pulls the board back;
(3) Starting from the station, there was a gap between the boards one after another.\
4. Observe the time of board collection at the last station of the assembly line, that is, the time of actual output. The time of this station must be equal to that of the bottleneck station. From this station, we can calculate the efficiency of this assembly line
5. Observation of grain movement rate of the assembly line
Labor rate = working time / working time of the whole day
The so-called Jiadong is an effective work on the assembly line. The operator sitting on the seat does not mean that he is working. Only when he is working can he make products, so we should observe the operator’s time in operation. But in fact, it is impossible to measure each operator all day, so there is a method of job spot check to simulate the measurement. In fact, it means to see what the operator is doing from time to time.
- The assembly line operator sitting in his seat does not mean that he is serious about his work, so the last thing is to observe the operation speed of each operator. Speed of the assembly line is a very abstract concept. It is difficult to compare and quantify from the visual point of view. Therefore, it is good to establish a standard speed in the heart. If it is faster than it, the action is simplified, fixed and rhythmic, and often has a better operation speed. On the contrary, if it is poor, it is easier to observe in this way.
Assembly line operation is either fast or good. Its action must have added value, so it depends on whether its action is simple and concise. Therefore, the concept of action economic principle is required. In short, the actions of human hands can be divided into movement, grasping, release, front, assembly, use and decomposition, as well as a psychological spiritual function. Strictly speaking, only two actions have added value: assembly and use, Therefore, under the condition of meeting the production requirements, other actions shall be eliminated or simplified as far as possible.
