Set up a team to prepare for the SMED study.

List of items needed for conducting SMED research

Equipment list:

camera

videotape

stopwatch

tabula rasa

projector

A video recorder/TV set

Bill of materials:

film

scotch tape

scissors

notebook

Marker pen

Bulletin board

Observe and record the detailed process of current switching.

Shoot the whole process of switching, don't pause in the middle, so that you can analyze the time of each step with video.

Pay attention to switching hands, eyes and body movements.

Check the video content in the conference room and record the time of each activity with a stopwatch.

Observation switch-using bulletin board

List every step of opening the pink notice sticker.

Record the time of each step on the white notice sticker.

Record the observation results on the yellow bulletin board.

Operator, get the wrench.

Go to the parts cabinet

The head of the clamp is difficult to locate on the machine.

Show the current situation in the form of a chart.

Describe the present situation in short language.

Describe the current situation in words, including the duration of the switch, who usually completes the homework, and the special events that occurred during the switch. Including people, tools, parts, etc.

Two operators make three kinds of switching, and the process includes:

Replace the lifting head, frame and feed pipe;

Select a new program;

Adjust the material tube separator, bottle guide, box seal and coding.

Set improvement goals

Write down the target, including the target value of switching time and the time period that needs improvement. This is only the prediction of SMED team members on the reduction of switching time, but the final result is usually better than the prediction.

According to the three stages of SMED, the improvement scheme is formulated and implemented step by step.

Step 1: Distinguish between internal work and external work.

Step 2: Transform internal operation into external operation.

Step 3: Optimize all aspects of the handover operation.

Check the results obtained.

Standardize switch operation and train operators.

[editor] the benefits of ]SMED

Flexible production

No extra inventory is needed to meet customer demand.

Quick delivery

Shortening the delivery time means that extra inventory will not bring financial pressure.

Superior product

Reduce possible errors in the adjustment process.

Effective production

Shortening the switching downtime means higher production efficiency, which means the improvement of OEE.

It can realize JIT and greatly reduce product scrap.

SMED has two main benefits:

Improve process productivity

Increase the frequency of line changing
