いて充填時間を予測計算することにより、人手に頼って
いた作業を自動化するようにした方法の提案がある。Conventionally, as a method of filling the above-mentioned tire with a gas such as air after assembling a rim, for example, a filling time is estimated and calculated by using an initial tire internal pressure, an intermediate pressure, and a target pressure for each size after assembling. There is a proposal of a method for automating a task that has relied on human labor by doing so.

とができず、充填効率が一層低下する欠点があった。However, in such a method, it is difficult to set the target pressure in one predicted filling time, and the process of measuring the tire internal pressure after filling, predicting and calculating the filling time again, and performing filling is performed many times. There is a problem that it is necessary to repeat the process and it takes a long time to fill. Moreover, if there is a fluctuation in the flow rate of the gas to be charged, it is controlled by time,
If the filling and measurement are not repeated, the target pressure cannot be attained and the filling efficiency is further reduced.
