In the stopped state, the moving unit 6 attempts to move further to the mission 1 side.

As a result, the engine 2 is
The (supporting portion 11) is in a state of being relatively retracted, and the second substrate 20 of the rotary operation mechanism 7 is relatively retracted with respect to the first substrate 19 via the output pulley 2b of the engine 2, and is moved from the stopper 19a. Because it ’s away, engine 2
The retreat of the (support portion 11) is received by the spring 21 and the damper 22 with less shock.

As shown in FIG. 5, the engine 2 (support 11) and the second substrate 2
When 0 is relatively retracted, this state is detected by the retreat detection sensor 32 provided on the damper 22, and the moving unit 6 (the operation cylinder 9) stops, and conversely, as shown in FIG. As a result, the moving unit 6 is moved to the side opposite to the mission 1. When the moving unit 6 is moved to the side opposite to the mission 1 in this manner, the engine 2 (supporting unit 11) and the second substrate 20 of the rotary operation mechanism 7 are moved by the urging force of the spring 21 in accordance with this. 6, the second substrate 20 of the rotary operation mechanism 7 contacts the stopper 19a.

In such a state, the reverse detection sensor 32 is in the non-detection state, and as shown in FIG. 7, the moving section 6 is again moved to the mission 1 side by the operation cylinder 9, and at this time, Also, as described in the preceding section [5], the output pulley 2b of the engine 2 and the output portion 12a of the clutch 12 are operated to rotate. Accordingly, when the output portion 12a of the clutch 12 reaches the input shaft 1b of the mission 1, if the phase of the spline at the input shaft 1b of the mission 1 matches the phase of the spline at the output portion 12a of the clutch 12, the clutch 12
The input shaft 1b of the mission 1 is inserted into the output unit 12a of the transmission 1.

At the same time, the flange 2a of the engine 2
Is inserted into the connection hole 1c of the flange 1a of the transmission 1, and the bolt attached to the connection hole 1c of the transmission 1 is inserted into the connection hole of the flange 2a of the engine 2. When the flange portion 2a of the engine 2 comes into contact with the flange portion 1a of the transmission 1, the moving portion 6 (operation cylinder 9) stops. In this case, as described in the preceding item [4], when the model of the engine 2 is first input to the control device (not shown), the second
The position where the moving unit 6 (operation cylinder 9) stops relative to the base 4 (the position where the flange 2a of the engine 2 contacts the flange 1a of the transmission 1) is recognized, and the moving unit 6 is detected by the position sensor 10. While the position of 6 was detected,
The moving unit 6 (operation cylinder 9) is stopped.

As shown in FIG. 7, even if the moving section 6 is again moved to the mission 1 side by the operating cylinder 9, the input shaft 1b of the transmission 1 is not inserted into the output section 12a of the clutch 12, and For engine 2 (support 1

It is moved again to the mission 1 side (see FIG. 7). Even if such an operation is repeated a set number of times (for example, about three times), the mission 1 is output to the output unit 12a of the clutch 12.
If the input shaft 1b is not inserted, it is determined that there is something abnormal, the coupling device stops, and the alarm is activated.

As shown in FIG. 7, the output unit 1 of the clutch 12
The input shaft 1b of the mission 1 is inserted into 2a, and the bolt 35 attached to the engine 2 and the flange 2a of the transmission 1 is inserted into the connection hole 1c of the flange 2a of the engine 2 and the transmission 1. When the moving unit 6 (operation cylinder 9) stops at a position where the flange 2a of the engine 2 comes into contact with the flange 1a of the transmission 1, the engine 2 and the transmission 1 are transported to another position, and the engine 2 and the transmission 1 flange portion 2a,
The bolt 35 attached to 1a is tightened, and the connection between the mission 1 and the engine 2 is completed.

[7] As described in the preceding paragraphs [4], [5] and [6], when one type of engine 2 is connected to the mission 1, but a different type of engine 2 is connected to the mission 1, When the model of the engine 2 is input to the control device, the second base 4 (support of the engine 2 (support portion 11)) is moved from the state shown in FIGS. The position is set, and the positioning unit 13a is set at the contracted position where the positioning cylinder 13 is contracted. The position where the moving unit 6 (operation cylinder 9) stops relative to the second base 4 (FIG. 1) 7, the position at which the flange 2a of the engine 2 contacts the flange 1a of the transmission 1) is changed,
