Production line
The characteristic of the production line is that each process is completed by a specific person, and each person is processed step by step to do a specific job
The advantage is that production will be faster in this way, Because everyone only needs to do one thing and they are very familiar with what they are doing
The disadvantage is that people who work will find it very boring
Characteristics of the Huadu production line
Degree of professionalization of the work place high.
The process is closed, the work places are arranged in process sequence, and the labor objects move in one direction between the processes
The processing time of each process is consistent with the proportion of the number of work places in each process.
Every process is produced according to a unified rhythm. The so-called cycle time refers to the production time interval between two adjacent products.

According to the way of realizing rhythm, it can be divided into forced rhythm flow production line and free rhythm flow production line.
According to the degree of mechanization, it can be divided into three types of production lines: manual mechanization and automation.
Huadu Production Line Optimization
The assembly line plays an important role in industrial production. Optimizing the assembly line is directly related to the quality of the product and the efficiency of production, so it has become a topic that companies have to pay attention to.
Optimize the operation time of the first station of the assembly line and how long it takes to put a board. This is the necessary investment time to meet the production plan. But in fact, the operation time of the bottleneck station must be longer than that of the first station. The first station must not be the bottleneck station, so the first station may not necessarily devote the required time because the bottleneck station has slowed down its speed. From a management point of view, the first-station operators must be required to invest at the specified speed. The conveyor belt speed of the assembly line can also be used to calculate the daily output. The following is the formula for the conveyor belt speed:
The conveyor belt’s time, the whole day’s working hours/daily output* (+ defective rate)
The conveyor belt’s Speed mark spacing distance/conveyor belt time
The so-called mark spacing distance is the distance between the marks made on the belt of the assembly line. It is expected that the operator will complete the work according to the speed of the mark flow and place it on the belt line. The lines are not marked, so the length of the board is used as the marked interval. Why use conveyor belts? In addition to transporting items, it also has the function of semi-forcing operators to complete operations according to plan. However, it is not a matter of speeding up and trying, but should be calculated according to the above formula.
Observe which station on the assembly line is the bottleneck station:
The station that is always busy
The station that always pulls the board back
Starting from this station, one after another A piece of board with a gap in the middle.
The above three points can be detected visually, and then measured with a stopwatch. The operation time is the longest among all stations.
The operating time of the bottleneck station becomes the actual output time of the entire assembly line, and the daily output formula is as follows:
The daily output is the actual working time/actual time of the whole day
So on-site cadres As long as the operation time is reduced, the output can be significantly improved, such as taking some parts to other stations for processing, using machining tools to save movement, improving the configuration of the work area, etc. However, after the bottleneck station is solved, a new bottleneck station may appear, so this new bottleneck station needs to be improved. Therefore, by continuing to focus on the improvement of the bottleneck station, the efficiency of the entire assembly line will increase day by day.
Observe the time of collecting boards at the last station of the production line, which is the actual output time. The time of this station must be equal to the bottleneck station. The efficiency of this assembly line can be calculated from this station. The formula is as follows:
Efficiency input time/actual time operating time of the first station/operating time of the last station
Of course, the efficiency of the bottleneck station can also be used In terms of operation time, it is always simpler and more practical to observe the last stop.
The quantity of work-in-progress on the assembly line is equal to:
(The operating time of the last station and the operating time of the first station) * (The working time of the whole day/The operating time of the last station)
Observation of the utilization rate
The utilization rate is based on the working time/the working time of the whole day
The so-called utilization refers to the effective work on the assembly line. Just because the operator is sitting on the seat does not mean that he is working , Products can only be made when the operator is working, so it is necessary to observe the time when the operator is working. But in reality, it is impossible to measure every operator throughout the day, so there is a method of spot checks at work to simulate measurements. In fact, to put it bluntly, it means to see what the operators are doing from time to time.
Just because a Huadu production line operator is sitting on his seat does not mean that he is working seriously, so the last step is to observe the working speed of each operator. Speed is a very abstract concept, and it is difficult to judge by visual inspection alone. Comparison and quantification, so establish a standard speed in your mind. If it is faster than it, it is considered good. If the movements are concise, fixed and rhythmic, the work speed will usually be better, and if it is not, it will be easier to observe.
Assembly line operations are either fast or good, and their actions must have added value, so it also depends on whether the actions are simple and concise, so the concept of action economic principles is required. Simply put, the actions of human hands can be divided into There is also a psychological and spiritual effect in releasing the pre-assembly and use decomposition for mobile grasping. Strictly speaking, only two actions have added value: assembly and use. Therefore, under the conditions that can meet production requirements, try to exclude or Simplify other actions. The principles are as follows:
Movement: Make the material reach the desired position automatically, shorten the moving distance, reduce the weight of the items to be moved, avoid things around the moving path that will hinder the movement, place the material box at an angle to shorten the distance around the edge, etc.
Handling: The materials in the material box should be arranged as neatly as possible. Do not pile up things in a cluttered manner and reserve space for holding things that are inconvenient to take.
Front placement: Just like holding, the materials in the material box should be arranged neatly and should not be piled up in a messy manner.
Organization: Use tools to replace manual work, etc.
Use: To fully automate machinery, etc.
Psychological effect: Use machinery to replace human judgment and reduce the movement of the operator's eyes, etc.
Precautions for installation of Huadu production line:
The graphic design of the assembly line should ensure the shortest transportation route of parts, easy operation by production workers, convenient work of auxiliary service departments, the most effective use of production area, and consider assembly line installation. The mutual connection between them. In order to meet these requirements, issues such as the form of the assembly line and the arrangement method of the assembly line installation worksite should be considered when laying out the assembly line layout.
When installing the assembly line, the arrangement of the work places must conform to the process route. When a process has more than two work places, the arrangement method of the work places in the same process must be considered. Generally, when there are two or more even-numbered working places of the same type, a double-row arrangement should be considered and they should be arranged on two sides of the transportation route. But when one worker is tending multiple pieces of equipment, consider keeping the distance the worker moves as short as possible.
