いる。[Prior art] Conventionally, as this type of device, for example,
The one described in Publication No. 22718 is known. In other words, it connects to the ATF flow path that connects to the oil cooler, extracts the old ATF that is discharged from the ATF flow path as the engine operates, and simultaneously pumps new ATF into the ATF flow path to almost completely remove the ATF in the automatic transmission. Devices have been proposed that can be replaced over the entire capacity.

Also, it is discharged
The amount of ATF fluctuates depending on the engine speed, and there is no way to accurately determine the amount of oil drained and refilled, so it is difficult to stop the amount of oil drained and refueled at a constant rate. After completing the replacement, it was a hassle to always check the ATF level in the automatic transmission and then adjust the level based on this.

Here, if it is predicted that a full tank of waste oil or a shortage of new oil will occur, the monitor lamp 29 will light up the corresponding item, and the alarm output unit will output an alarm (4) and (5), and the flow will be terminated. In this case, the operator only needs to follow the support of the monitor lamp 29 to drain the waste oil from the waste oil tank 7 or replenish new oil to the new oil tank 10 and restart the process.

ATFがATF流路Ｄへ圧送される。 If it is determined in steps (2) and (3) that the tank is full or does not run out, the pump 8 is driven, the solenoid valves 6 and 9 are opened, and the solenoid valve 12 is closed to start replacement.
(6). Along with this, the old ATF in the automatic transmission flows into the waste oil tank 7 from the oil drain hose 2, and at the same time, the new ATF in the new oil tank 10 flows from the new oil hose 3.
ATF is forced into the ATF flow path D.

ステツプ(16)を実行することはない。 Next, check whether there is a stop input from the start/stop key 31 (9), whether the refueling amount Q2 has reached the set amount Qp (10),
It is checked whether the amount of oil drained Q1 has reached the set amount Qp (11), or whether the exchange has been completed in which both the amount of drained oil Q1 and the amount of oil supplied Q2 have reached the set amount Qp (12).
If none of the above apply and it is determined that the exchange is continuing,
Based on the amount of oil discharged Q 1 and the amount of oil supplied Q 2 , the difference Q 2 −Q 1
Checks whether it exceeds a predetermined value a (0 to 0.5) or is below a predetermined value b (0 to -0.5) (13), (14), and if it exceeds a, closes the solenoid valve 6. While the pump 8 remains open, the pump 8 is stopped to allow oil to be drained first (15), and if it is below b, the pump 8 is kept in operation while the solenoid valve 6 is closed to allow oil to be supplied first (16). Also, the amount of oil discharged Q 1 and the amount of oil supplied Q 2 are within a predetermined range b
If <Q 2 −Q 1 <a and the pump 8 is approximately balanced, the pump 8 is maintained in an operating state and the solenoid valve 6 is maintained in an open state (17). Note that in the device of this embodiment, the engine
Since the amount of oil supplied by the pump 8 is set to exceed the amount of oil discharged during idling, normally step (16) is not executed.
以上のように、ステツプ(7)〜(17)を繰り返して

出力して(20)一連の動作を終了する。 As described above, the replacement progresses by repeating steps (7) to (17), and in step (10), the oil supply amount Q 2 reaches the set amount.
When it is recognized that Qp has been reached, the pump 8 is stopped and oil supply is stopped (18), and when it is recognized that Q1 has reached the set amount Qp in step (11), the solenoid valve 6 is closed and oil drainage is stopped. Do(18). In this way, when both the oil discharge amount Q 1 and the oil supply amount Q 2 reach the set amount Qp, and it is determined that the replacement has been completed in step (12), the solenoid valve 9 is closed and the solenoid valve 12 is returned to the open state. Then, an alarm is output (20) and the series of operations is completed.

０）を介してフローを終了する。 Also, when a stop input is detected in step (9), first the difference between the oil supply amount Q 2 and the oil discharge amount Q 1 is within a predetermined range −α.
Check whether <Q 2 −Q 1 <α (α=0 to 0.1). In other words, the amount of oil supplied Q 2 is the amount of oil discharged Q 1
Checks whether the oil discharge amount Q 1 exceeds the predetermined value α (21) and whether the oil discharge amount Q 1 exceeds the oil supply amount Q 2 than the predetermined value α (22). If the oil supply amount exceeds the predetermined value α, the pump 8
(23), and if the amount of oil discharged exceeds the amount, first close the solenoid valve 6 (24) and adjust so that the amount of oil supplied and the amount of oil discharged are approximately equal. In this way, when the amount of oil drained and the amount of oil supplied become almost equal and the difference between them falls within the predetermined range, both oil drain and oil supply are stopped (25), and step (2)
0) to end the flow.

作を停止できる。 Therefore, according to this embodiment, simply by connecting the oil drain hose 2 and the oil supply hose 3 to the ATF flow path D and inputting a key, the set amount of ATF can be exchanged automatically, which eliminates the need for troublesome manual work. Even inexperienced workers can easily complete the work. In addition, as seen in steps (13) to (17), the amount of oil drained and the amount of oil supplied are constantly monitored, and if the difference between them deviates from a predetermined range, either the solenoid valve 6 or the pump 8 is controlled. In automatic transmissions, the balance operation is performed so as not to go too far ahead.
There is no need to worry about mixing air into the ATF or causing overflow. Furthermore, as shown in steps (21) to (26), if the replacement operation is stopped by the start/stop key 31 before the set amount is reached, the difference between the amount of oil supplied and the amount of oil drained at that point is checked. However, if there is a difference of more than a predetermined value between the two, the oil supply and oil drain are stopped with a time difference so that they are approximately equal, so that the ATF in the automatic transmission can be always maintained at a predetermined level and the operation can be stopped.
［考案の効果］
この考案は以上のように構成されるもので、以
下のような効果を奏する。[Effects of the invention] This invention is configured as described above, and has the following effects.
従来のように手作業で流量調節をする必要がな
く作業が簡易で、作業者に熟練を要することもな
い。 There is no need to manually adjust the flow rate as in the past, the work is simple, and the operator does not need to be skilled.
また、停止入力時には排油量と給油量との差に
基づいて排油と給油とに時間差を持たせて停止す

換前後で自動変速機内のATFレベルが変動する
ことがないから、作業後改めてATFのレベル調
整をする必要がない。 Furthermore, when a stop is input, the oil drain and oil supply are stopped with a time difference based on the difference between the oil drain amount and the oil supply amount, so the oil drain amount and oil supply amount are maintained at approximately the same amount, and the oil is automatically changed before and after oil replacement. Since the ATF level inside the transmission does not change, there is no need to adjust the ATF level again after work.
