What Are the Different Types of Assembly Line Systems?

According to different work processes, the production system can be divided into Flow-Line production, Fixed-station production (Fixed-Location), Job production (Job-Shop). Pipeline production is a typical production mode for large-scale production type enterprises. It has high production efficiency, but has poor adaptability and insufficient flexibility.

Depending on the workflow,

FIG. 7 is a flow chart of the pipeline process, and the software flow chart of the system is designed as shown in FIG. 8. It consists of sequence control, temperature control, set value reading, and numerical output display. ^[3]

In the virtual pipeline mode, several processed workpieces or assembly main parts are fixed on a work platform (work station) without moving. And personnel, equipment (movable) and tools flow between different stations in a certain order to complete the assigned processing tasks. This flow of people, equipment and tools constitutes the "personnel flow" and "equipment tool flow". For the same workpiece to be processed, its entire processing task is completed by different operators in sequence; for the same operator, the same or similar processing tasks are repeatedly completed between different stations. From the physical space, the processed workpieces are fixed, but logically, the workpieces are sequentially processed in relative flow between different personnel and equipment tools. Therefore, "virtual" is used to describe this logical flow of workpieces, resulting The concept of "virtual pipeline". Through the virtual pipeline operation, not only the high efficiency of the production process is achieved, but also the production has better flexibility. Compared with traditional assembly line production, the main features of virtual assembly line are:

1) The virtual assembly line uses a combination of personnel, equipment and tools instead of the flow of huge workpieces, which reduces the cost of the assembly line and is easy to implement

2) It has the characteristics of high efficiency of the production line mode and high flexibility of the fixed production mode;

3) Adopt soft beats instead of hard beats. Only by changing and adjusting the production organization, you can control the production beats;

4) Compared with fixed production mode, it is convenient for production management and control;

5) Conducive to improving the quality of operations and product quality, and facilitate the realization of product quality control. ^[1]
