Garment Factory Assembly Line Layout, Seven Principles To Abide By

World clothing shoes and hats,

What is the principle of pipeline layout? It can be summed up simply as follows: "two observance and two evasion".

Two compliance: anti clockwise arrangement, consistent entry and exit.

Two evasion: island layout and birdcage layout; one of the ideal layout of unit assembly line is petal layout.

Seven principles of lean production line layout

1. fluency principle: organic integration of all processes, centralized operation of related processes, and streamlined layout principles.

2. the shortest distance principle: minimize the handling, and the process can not be crossed and run in a straight line.

3. balance principle: resource allocation between stations and speed allocation as far as possible.

4. the principle of fixed cycle: minimize the movement of Non-Value Added, such as handling.

5. the principle of economic output: to adapt to the situation of minimum mass production, make use of space as much as possible, and reduce ground placement principles.

6. flexibility principle: resilience to future changes and flexibility.

If it is small batch and multi type products, give priority to "U" line layout, ring layout, etc.

7. the principle of error proofing: we must consider this principle as fully as possible in the production layout. The first step is to prevent errors from the hardware layout and reduce the loss in production.

1. counter clockwise arrangement

Counterclockwise arrangement, the main purpose is to hope that employees can use one person end operation mode, to achieve one person more machine.

One person ends with one person with multiple machines, requiring an employee to finish from scratch, so the employee is dynamic, known as "itinerant operation".

Most of the workers are right - handed, so if the job is done against clockwise, when the employees carry out the next processing operation, the fixture or parts are on the left side, and the staff work is not convenient. This is the purpose of counterclockwise - the staff will go to the next station - the purpose of the patrol is achieved.

2. unanimous pfer

The same entry and exit means the entry of raw materials and finished products together.

Why do we ask for consistency?

First, it helps to reduce empty handed waste.

Assuming that the entrance and exit is not consistent, the operator uses the itinerant operation. When a product is finished, the raw material will be processed again, and the operator will be empty handed.

If the entrance and exit are unanimous, the operator can immediately pick up new raw materials for processing, thereby avoiding empty handed waste.

Second, is conducive to balancing the production line.

Because of the uniform entrance and exit, the layout will be similar to the "U" shape, which makes the process very close, thus providing a possibility for a person to operate multiple processes at the same time, which improves the flexibility of process allocation and achieves a higher production line balancing rate.

3. avoid isolated island layout.

The islanding layout divides the production line into separate working units. The drawback is that the units and units are isolated from each other and can not help each other.

4. avoid birdcage layout.

Bird cage layout often does not take into account the smooth flow of logistics and human flow. The layout of the layout is erroneous by using machine equipment or worktable to encircling the operator in the middle, making the logistics not smooth, WIP increases, and the mutual support between units and units has become almost impossible.

5. petal layout

Petal shaped layout is composed of multiple units, which is the result of layout according to the principle of "two complying and two evading".

This layout helps improve mutual assistance between units, thereby improving the line balancing rate.

Petal layout is a necessary condition for "mutual assistance and cooperation".

Mutual assistance is like relay race in sports field. In the handover area, strong players can make up for the weak players properly.

The same is true in work, and the operators between units should pass the products as batons.

If the operator in the front unit delays the time, the operator in the back unit will help the former unit unload the product from the machine.

This practice obviously depends on the petal style layout.

6. "one flow" production line layout

According to the concept of lean production, in addition to the above two aspects, there are more important factors to consider, lean.

The main objectives are as follows:

1, minimize material handling cost;

2, the effective use of space;

3, effective utilization of labor force;

4, facilitate communication between employees, between employees and managers, between employees and users.

A flow (One - Piece Flow) production mode refers to the product in the production process as far as possible to achieve a small batch of rotation, preferably single piece flow.

It is the best way to reduce the number of WIP and eliminate the waste of production line.

Its foundation is to make the processing line flow like the assembly line, but at the expense of the utilization ratio of the non bottleneck process equipment, we should try to balance the production line as far as possible and reduce the loss of the capacity of the equipment.

7. "U" layout

The layout is generally classified into two categories: the traditional "one" production line layout (that is, arranging the equipment according to the processing sequence) and the U-type layout.

With the promotion of lean production ideas, traditional production lines are increasingly being replaced by U production lines, because the traditional production line layout has the following disadvantages: when a person operates multiple devices, there will be a "waste of walking", which increases labor intensity, and at the same time can not achieve flexible adjustment of personnel.

In the U layout, the production line is like U, and the outlet and population of a pipeline are in the same position. One processing site may contain several processes at the same time, so the U layout needs to train multi energy workers.

It reduces walking waste and workspace, shortens cycle and improves efficiency. At the same time, it also reduces operators and reduces costs.
