タイヤ内圧が下降する。Therefore, if the supply valve is opened while the discharge valve is closed, air is supplied to the inside of the tire 1, the tire internal pressure rises, and the discharge valve opens when the supply valve is closed. When the condition is reached, the air inside the tire 1 is exhausted to the outside,
The tire pressure drops.

７から空気供給手段４に停止信号が入力され、空気供給
が停止する。（つまり、供給弁が閉状態となる。）The detection means 6 is, for example, a pressure detection sensor such as an electropneumatic converter, and when the tire internal pressure reaches a predetermined maximum value (for example, 9 kg / cm 2 ), the control means 6 controls this. 9 and the transmission signal is input from the control means 9 to the supply stopping means 7, and when the transmission signal is input, the stop signal is input from the stopping means 7 to the air supply means 4 and the air supply is stopped. (That is, the supply valve is closed.)
【００１６】そして、タイヤ内圧が所定最小値（例え

Is inputted and a transmission signal is inputted, a stop signal is inputted from the stopping means 8 to the air discharging means 5,
Air discharge stops. (That is, the discharge valve is closed.)

所定時間カウント後、排出作動信号が空気排出手段５に
入力され、排出手段５による空気排出が行なわれる。In this case, however, the timer operating signal is input from the control means 9 to the timer 10, and after the timer 10 counts a predetermined time, the exhaust operating signal is input to the air exhausting means 5 and the air exhausting means 5 operates. Ejection is performed.
【００１８】また、制御手段９からは供給作動信号が空
気供給手段４に入力され、空気供給手段４による空気供
給が行なわれる。Further, a supply operation signal is input from the control means 9 to the air supply means 4, and the air supply means 4 supplies air.
【００１９】従って、タイヤ内圧が最大値に達すれば、
直ちに空気供給弁が閉状態とされ、その状態で所定時間
保持された後、空気排出弁が開状態とされるものであ

The air supply valve is immediately closed, and the air exhaust valve is opened after being kept in that state for a predetermined time, so that the tire shape is maintained.
【００２０】次に、図４と図５に示すフロチャートに従
って、ポストキュアインフレータの動作を説明する。Next, the operation of the post cure inflator will be described with reference to the flowcharts shown in FIGS. 4 and 5.
【００２１】即ち、加硫済のタイヤ１を図３に示すよう
に上下のリム２，３に装着して後、スタートさせる。That is, the vulcanized tire 1 is mounted on the upper and lower rims 2 and 3 as shown in FIG. 3 and then started.
【００２２】スタートすれば、図４に示すように、空気
供給弁が開状態となると共に、制御手段９の図示省略の
タイマ（ＰＣＩ時間をカウントする）が作動する。When the engine starts, as shown in FIG. 4, the air supply valve is opened and the timer (not shown) of the control means 9 (counts PCI time) is activated.
【００２３】そして、図４に示すように、タイヤ内圧が

する。空気供給弁を閉状態とした後は、所定時間経過し
たか否かが判断され、経過していなければ経過するまで
待ち、経過すれば、空気排出弁を開状態とする。Then, as shown in FIG. 4, it is judged whether or not the tire internal pressure has reached a predetermined maximum value, and if not reached, wait until it is reached, and if reached, the air supply valve is closed. After the air supply valve is closed, it is determined whether or not a predetermined time has elapsed. If not, the process waits until the time elapses, and when the time elapses, the air exhaust valve is opened.
【００２４】次に、内圧が所定最小値に達したか否かが
判断され、達していなければ、達するまで待ち、達すれ
ば空気排出弁を閉状態とする。Next, it is judged whether or not the internal pressure has reached a predetermined minimum value, and if it has not reached it, it waits until it reaches it, and if it does, the air exhaust valve is closed.
【００２５】しかして、図４に示す動作中においては、

As shown in FIG. 5, it is determined whether or not the air supply valve is operating and the PCI (post-cure inflator) time has elapsed, and if not, it is determined whether the air supply valve is open. Then, if the air supply valve is in the open state, the process proceeds to A and it is determined whether the internal pressure has reached the maximum value as described above.
【００２６】そして、空気供給弁が開状態でなければ、
つまり、空気供給弁が閉状態であれば、空気排出弁が開
状態か否かが判断される。If the air supply valve is not open,
That is, if the air supply valve is in the closed state, it is determined whether the air discharge valve is in the open state.
【００２７】空気排出弁が開状態であれば、Ｂに進み、
Ｂに進めば、図４に示すように、内圧が最小値に達した

Proceeding to B, as shown in FIG. 4, it is determined whether or not the internal pressure has reached the minimum value. If the air discharge valve is not in the open state, that is, if the air discharge valve is in the closed state, the process proceeds to C, and if the process proceeds to C, the air supply valve is opened as shown in FIG.
【００２８】また、ＰＣＩ時間が経過すれば、空気供給

了する。When the PCI time elapses, it is determined whether or not the air supply valve is in the open state. If it is in the open state, the air supply valve is closed, and if it is in the open state, the air discharge valve is closed. Whether it is in the state or not is judged. If it is in the closed state, the air discharge valve is opened, and if it is in the open state, this air supply / discharge operation is completed.

大幅に短縮し、しかも、冷却水を使用しないので、装置
が錆びたり、タイヤ１が不均一に冷却されたり、冷却水
がタイヤ１に残留する等という不都合がない。Therefore, as shown in FIG. 2, when the post-cure inflator operates, the internal pressure increasing step 11 for supplying air into the tire 1 to increase the tire internal pressure to a predetermined maximum value, and the air inside the tire 1. And the internal pressure lowering step 12 for discharging the internal pressure of the tire to a predetermined minimum value are sequentially repeated a plurality of times within a predetermined time, the air in the tire 1 is sequentially replaced, and the cooling time is significantly longer than that of standing cooling. Moreover, since the cooling water is not used, there is no inconvenience that the device is rusted, the tire 1 is unevenly cooled, and the cooling water remains on the tire 1.
【００３０】次に、実験例を示す。Next, an experimental example is shown.

備え、ブレーカーとしてナイロンコード入プライを２層
備えたものとする。That is, as Experimental Example 1, comparison was made between the case where the internal pressure was maintained at a predetermined value and the case where the maximum value (9 kg / cm 2 ) was the same and the minimum value was different. The conditions of Experimental Example 1 are shown in Table 1 below. As the tire, a cross-ply tire of 10.00-20-14PR specification is used, and a case is provided with six layers of nylon cord-containing plies and a breaker is provided with two layers of nylon cord-containing plies.
【００３２】[0032]
【表１】 [Table 1]
【００３３】この場合、１サイクルを、内圧上昇工程→

とし、このサイクルを５回繰り返した。In this case, one cycle consists of the internal pressure increasing step →
The internal pressure decreasing step → the internal pressure increasing step was performed, the required time was 9 minutes, and this cycle was repeated 5 times.

た。Then, according to the conditions shown in Table 1,
5 tires of e, rim 7.50V, internal pressure 6.75 (kg / c
The tire outer diameter D and the tire total width E (see FIG. 3) were measured after standing for 24 hours as m 2 ), and the results are shown in Table 2.
【００３５】[0035]
【表２】 [Table 2]
【００３６】即ち、ロのタイヤ及びハのタイヤは、従来

夫々僅かに小となり、ホのタイヤでは、内圧が低すぎる
ためＰＣＩ効果（つまり、補強コードが収縮してタイヤ

が薄いことがわかる。That is, the tires of B and C are the same as the tires of A by the constant internal pressure system which is the conventional method, and the tire outer diameter D and the total width E of the tire of D are slightly smaller. Therefore, in the tire of E, the internal pressure is too low, so the PCI effect (that is, the effect of preventing the reinforcement cord from shrinking and the tire from having a predetermined shape)
You can see that is thin.
【００３７】次に、実験例２として、内圧最大値を９kg

/ Cm 2 and R = 30%, the PCI times were varied and the results are shown in Table 3.
【００３８】[0038]
【表３】 [Table 3]
【００３９】従って、内圧の最大値を９kg／cm2 とした

If you change the air in the tire 1 by changing the
The PCI time (post-cure inflator time) can be reduced to about 3/5 as compared with the case where it is not changed.

For example, the predetermined maximum value and the minimum value of the tire internal pressure can be freely changed. The internal pressure increasing step 11 and the internal pressure decreasing step 12 can be freely changed even when the predetermined time is repeated. Further, the cycle time for repeating the internal pressure increasing step 11 and the internal pressure decreasing step 12 can be freely changed.
