Action Improvement Education | Essentials
① make too much waste
② waste in the library
③ to create a waste of bad products
④ the waste of action
⑤ waste of processing
⑥ waiting for a waste
⑦ waste of handling
<Each STEP goal>
STEP ①: the worst waste (making too much waste) the exclusion of other waste is significant
STEP ②: individual action improvement, complete ST cut
STEP ③: ST changes, re-design operations, waiting for the exclusion of waste
STEP ④: Design for the layout of the most suitable job design
With the same purpose but different ways of the situation, we find the difference of the action and make it clear that the feeling and consciousness that can combine the better action are called Motion Mind.
<Improved ECRS>
E: Eliminate not? → why is it necessary?
C: Can Combine not be reduced? → Can not work with other jobs?
R: Rearrange (configuration change) can not be close to it? → why is it there?
S: Simplify can not become a simple job?
The principle of action economy - the basic of action improvement
① a thorough elimination of waste action
② Simplification of operations
③ minimization of fatigue during operation
Case Description: ① a thorough elimination of waste action
(1) tamper (tour margin) to minimize
Market sales of the switch, such as foot and other switches have set off the remaining settings.
To this end, the foot of the moving distance is large, the operating time will be extended.
Moreover, it is easy to produce fatigue.
If the worker is in the work due to the tightening of the rubber band, shortening the operating time of the operator, but also reduce the fatigue.
（2）minimize the movement distance of the line of sight
（3）The moving distance is minimized by the stereoscopic configuration
When the operating range is flat, the distance can not be constrained by a certain range due to the shape of the fixture, the shape of the tray, the amount of the operating range.
Do close to the distance after the three-dimensional configuration, also reduced the moving distance and handling distance.
* However, the upper and lower travel distances are set to a minimum
（4）Select the job to clear the selected area
（5）Change the operation mode of 1 by 1 to uniform operation
Case Description: ② simple operation
(1) to grasp the minimized distance
(2) Minimization of chimeric ratio
Products, tools, etc. in the hole or groove of other objects inserted in the time.
The size of the insert is smaller than the size ratio of the opening of the target (the difference between the size of the insert and the size of the opening of the target is large).
Angle of the cut, so that the law ratio becomes smaller. (This ratio is called the chiming ratio)
(3) blind job exclusion
Between objects and objects, such as the assembly between the fixtures, will produce many blind parts, must be hand to explore the location, in the assembly will take a lot of time.
Set the orientation logo before blindly assembling the job, while eliminating the blind job while still changing the job content. The result is: to achieve the shortening of the operating time.
(4) We take picking position (space) We prepare
Under the parts covered with a soft liner, the following reasons to reduce the number of workers.
· Parts are not easy to slip
· Inside the parts can be inserted into the fingers / tweezers, easy to take parts
(5) to consider the color of the ruler and the color of the product
It is possible to easily find the product (defective) at the time of selection, and to improve the detection speed and the detection capability of the product.
The selection method is to use the opposite relationship (color: high ⇔ low, brightness: high ⇔ low, hue: complementary color relationship (red ⇔ green) when considering the color classification of the product (chroma, brightness, hue) , Green ⇔ yellow)), etc., use such a sort of ruler.
(6) governance with even to take the operation
The principle of operation is the simultaneous operation of both hands. Odd to take, both hands at the same time after work into a single-handed operation.
When the items on the fixture are even, you can perform both hands.
Case Description: ③ minimal work when the fatigue
(1) Set the runway when standing
When standing in the same place, the blood circulation will be bad, the feet will be swollen, and will increase fatigue.
In the work set to set the cross-wood, feet in the case of fixed can reduce fatigue.
(2) cover the hot metal plate with the face
When the product is processed on a hot metal plate, the hot air on the hot metal plate is scattered directly on the face.
Between the face and the hot metal plate set the shielding plate, you can ease the heat, the operation is easy.
Case Description: From analysis to improvement
(1) observe the operation, decomposition action.
(2) Eliminate unnecessary work. Review improvement case.
(3) to review the shortening of the necessary operating time to improve the case.
