SMED method (Single-Minute Exchange of Die) originated in the Toyota production site research to improve the operation of punch die installed for adjustment. Later, the factory TPM Consulting found that this method is widely used in Toyota's production site for all processing equipment drive change preparedness among job. After consulting collated factory TPM, SMED method has the following three basic elements: a strict distinction between "external operations preparedness" and "inside job preparedness" SMED Act requirements, and equipment must be installed for adjustment operations division related to " External preparedness operations "and" inside job preparedness "two categories. External preparedness operations are those installed for adjustment operations, internal preparedness operations are those installed for adjustment work only when the device is in a stopped state to run can be performed while the device is in operation performed. Both preparedness work must be strictly distinguished. Because only internal preparedness work really occupied downtime, so everything must be done outside preparedness work in process equipment operation, shall not occupy downtime. As the required mold, tool, pad member, fasteners and various tools. Equipment must be prepared in the course of the operation is completed, and placed next to the device is ready for use. The internal preparedness operations confined to "replace the mold or tool, as well as the necessary adjustments" and preparedness work had to stop in the device can be carried out in the state. In other words, once the device to stop functioning, workers only internal preparedness operations, but absolutely can not leave the equipment to carry out any external preparedness operations. If this is done, we will be able to complete the equipment in a very short time for the whole process equipment operation, the equipment quickly return to work status. It should be noted that a strict distinction between the right internal and external job preparedness preparedness operations, is an important foundation for the successful use of SMED method. Second, as the internal preparedness operations into external Kerb jobs as factory TPM Consulting statistics, if they can be dealt with separately internal preparedness operations and external preparedness operations, will be able to install the equipment swap adjustment time is reduced by 30% to 50%. But this is not enough, SMED law also requires internal job change preparedness preparedness as possible for external operations, which is the core SMED law. Because the internal real job preparedness occupation downtime, reduce internal preparedness work for downtime is extremely important. For example, due to the different heights of various molds, each time changing the mold, you must adjust the punch stroke. However, if we pass a padded piece of ways to make punch chess highly standardized, it can be removed for punch stroke adjustment. In general, the "adjustment" inside job preparedness takes time job most of the time. Accordingly, "adjustment" shortening of operation time, to accelerate the whole preparation is critical. One of the most important is that the internal operations into external preparedness preparedness operations. Third, shorten operation time preparedness including internal preparedness shorten operating time and shorter working time outside preparedness. As mentioned above, the internal operation time is to determine the preparedness of the entire transformation of the key factors to adjust the time. To this end, SMED method requires the necessary technical means and rationalize ways to minimize internal preparedness work time to speed up the entire conversion process. Such as the use of special rails, guide pins to remove the mold of the alignment. With special bolts, fast fixed mold or tool. Meanwhile, the external preparedness work must be improved and rationalized, so as to shorten the time outside preparedness. This is to accelerate the entire installed for the adjustment process, reducing the production volume is also very important.
