One, arranged counterclockwise

Arrange counterclockwise, the main purpose is to hope that the staff can use one person to complete the operation and realize one person with multiple machines.

One person completes, one person has multiple machines, and employees are required to complete from start to finish. The employees are dynamic, which is called "tour operation".

Most workers are right-handed, so if they are arranged counterclockwise, it will be inconvenient for them to work with the fixture or parts on the left when performing the next machining task. This is the purpose of counterclockwise: the employees go The next station-the purpose of the cycle. Achieved.

Two, the entrance and exit are the same

Consistent import and export refers to the simultaneous export of raw materials and finished products. Why do we need the same entrance and exit?

First, it helps to reduce the waste of empty hands. If the import and export are inconsistent, the operator uses mobile operation. When the product is completed and the raw material needs to be reprocessed, the operator will enter the raw material from the finished product export to the raw material empty-handed (not in hand), which is a waste of time.

If the entrance and exit are the same, the operator can immediately take new raw materials for processing, avoiding waste.

The second is conducive to the balance of the production line. Since the entrances and exits are the same, the layout must be similar to the "U" shape, making each process very close, providing the possibility for one person to operate multiple processes at the same time, improving the flexibility of process allocation, and achieving higher production efficiency. N line balance rate.

Third, avoid island layout

The island layout divides the production line into individual work units. The disadvantage is that these units are isolated from each other and cannot help each other.

Fourth, avoid cage layout

Bird cage layout often does not take into account the logistics, the result of the smooth flow of people, the wrong layout uses machines or workstations, surrounded by operators, which makes the logistics not smooth, increases the construction in progress, and supports each other between units. The economy is almost impossible.

Five, petal layout

The petal-shaped layout is composed of multiple units and is the result of the layout according to the principle of "two obeys, two avoids". Avoid both: island layout and cage layout).

This layout helps to improve mutual assistance between units, thereby increasing the balance of the production line. The petal layout is a necessary condition for "cooperation".

Mutual assistance is like a relay race on the sports field. In the handover zone, the strong can make up for the weak.

The same situation also occurs at work. The operator passes the product from one unit to another like a baton.

If the operator of the previous unit is delayed, the operator of the next unit helps the previous unit unload the product from the machine. This method is obviously based on the "petal" layout.

Six, "First-class" production line layout

According to the concept of lean production, in addition to the above two aspects, there are more important factors to consider. The goals of lean production layout mainly include the following aspects:

Minimize material handling costs;

Effective use of space;

Effective use of labor;

Promote the exchange of information among employees, between employees and managers, and between employees and users.
