How To Balance Production Line When Garment Equipment Is Flowed

1. outline of balanced production line

What do we mean by a balanced production line?

Analysis refers to the application of process analysis time study method, from grasp the sewing production line's present situation and compile, in order to achieve the purpose of the best design.

That is to say, the processing time of each worker's working procedure is uniform, and the loss caused by the increase of waiting work or semi-finished products can be reduced, and a smooth production line can be formed.

Shorten the production time.

In order to improve the production performance of the current production line, we must first grasp where the bottleneck process is, and how much efficiency can be achieved by improving the bottleneck process.

With the change of production volume, the number of suitable operators in the production line is determined.

During the production period, when the order quantity increases or decreases rapidly, the number of personnel in which process is to be properly reconfigured is studied.

When the new type of production sewing is started, when the production line is made into a production line, the factory that adopts the one-piece production process now can make use of the most appropriate process sharing to start the arrangement as soon as the production line starts.

2. implementation method of production line balance analysis

In order to grasp the actual state of the production line, the processing time and sequence of processes need to be graphically balanced.

The average time table was obtained based on the results of process analysis and time analysis. The so-called PT (operation average time) was based on the synchronization of separate operations and the average operating time per person.

PT is divided into the following 2 calculation methods.

To calculate the management limits, managers should calculate the upper limit and lower limit of the "management limit" on the production line, usually considering the management limit of more than 85%.

If the efficiency is set below 85%, it is necessary to consider modifying the flow production mode.

3. research and improvement proposals

Focus.

Compared with the current situation, we seek higher productivity and focus on the "bottleneck project".

The workers in the next process of bottleneck process will wait for the operation even if they operate normally.

The most obvious bottleneck

In general, there will be backups to supplement, but second and third of bottleneck processes often do not attract managers' attention.

For example, operators B and F in chart 3 are close to the upper and lower limits of management boundaries. As managers, we must also fully grasp the second and third bottleneck processes.

Improvement of bottleneck process.

Research and improve efforts to improve bottlenecks in the process of operation elements and methods of operation, in order to shorten the time required.

The operation of each factor in the bottleneck process is reassigned to the process before and after the net value of processing time is small.

Perform motion analysis to improve homework.

The purpose of shortening the working time is to improve equipment conditions and use sewing AIDS.

Change manual work for mechanical operation.

Changing the configuration of personnel.

Regularized aid operations.

If you do not pay attention to the following points, there will be an analysis error in the allocation of time when analyzing the production line balance.

Confirm the impact of raw material and accessories on the production line.

Adjusting the operation time makes it unnecessary for the operator to do extra work.

(unnecessary inspection and decontamination).

The time value of factor operation is obtained from the complex number of job data.

In order to reduce the causes of uneven distribution, we should investigate and propose feasible countermeasures.

In order to compile and rebuild the process, pay special attention to the technical ability of the sewing operator.

The key to redistribution should take full account of human factors.
