Hereinafter, the internal combustion engine trial operation in the above embodiment will be described. The first conveyor 11 supported by the pallet 2
The internal combustion engine 1 conveyed by the above is subjected to oil injection or the like while being conveyed to the second conveyor 12, and then transferred to the third conveyor 13. Next, the internal combustion engine 1 is transferred to the receiving conveyor 23 from the ends of the two conveyors 13 and 15 and from both the turntables 14 and 16 and to the empty warming device 20. In this warming device 20, warming-up operation is performed on the internal combustion engine 1. At this time, since the internal combustion engine 1 is located in the soundproof room 22, exposure to noise to the outside is prevented. Then, the internal combustion engine 1 that has completed the intended warm-up operation is transferred to the upstream transfer device 30 via the discharge conveyor 24.

The internal combustion engine 1 of the upstream transfer device 30 is transferred from both the turntables 32 and 34 to the seventh conveyor 41, and stands by at the end thereof. Then, the internal combustion engine 1 on the seventh conveyor 41 is transferred to the adjusting device 40 in a state where the empty adjusting device 40 is opposed to the end of the seventh conveyor 41 and stopped by the return traveling of the self-propelled carriage 44. The self-propelled trolley 44 having received the internal combustion engine 1 travels at a predetermined speed to the eighth conveyor 42 side, during which operation conditions such as idle adjustment, ignition timing adjustment, and exhaust gas adjustment are adjusted. Such an adjustment can be performed from all directions with respect to the internal combustion engine 1 by the worker walking on the worktable 45. Then, after the intended adjustment is completed, the self-propelled carriage 44 stops facing the start end of the eighth conveyor 42. Next, the internal combustion engine 1 on the adjusting device 40 is transferred to the eighth conveyor 42 and then transferred to the downstream-side conveying device 50.

The internal combustion engine 1 of the downstream transfer device 50 is a ninth engine.
The sheet is conveyed by a conveyor 51, and is distributed to a left and right tenth conveyor 54 by a sixth turntable 53 to be supplied. The internal combustion engine 1 transferred from the tenth conveyor 54 to the supply conveyor 63 is sequentially stored on the supply conveyor 63 in a front-loading manner. The stored internal combustion engine 1 is detected by the detection device 73, and the detection state is displayed on the display unit 74. At this time, in the inspection room 62, the inspection of the internal combustion engine 1 is performed by the inspection device 60.
9 and 71 are located outside the enclosure 61 and both passages 65 and 66
Is closed by doors 67 and 68.

In the inspection room 62, inspections such as noise, vibration, responsiveness, and water leakage of each part are performed by the operator's sensuality (for example, listening directly).
Since the inspection is performed in the inside, the measurement (judgment) can be performed accurately without being affected by the sound of the adjacent internal combustion engine 1 or external noise.

Such an inspection is not always performed in a fixed time, but may be performed by taking sufficient time for each internal combustion engine 1 according to the storage condition on the supply conveyor 63. That is, at the end of the intended inspection, the operator in the inspection room 62 visually checks the display unit 74 to check the number of storages, and when the number is small, the inspection may be continued more carefully. When the number of storages is large, the operation unit 75 is operated.

By this operation, the opening and closing doors 67,
68 is opened, so that the unloading-side self-propelled carriage 71 enters the inspection room 62 and stops at the other side of the inspection device 60. Next, the internal combustion engine 1 whose operation has been stopped is moved from the inspection device 60 to the unloading-side self-propelled vehicle 71.
The internal combustion engine 1 on the supply conveyor 63 is moved to the carry-in side self-propelled carriage 69. In this state, both self-propelled vehicles 6
9 and 71 are run, the carry-in self-propelled trolley 69 enters the inspection room 62 and stops at one side of the inspection device 60, and the discharge-side self-propelled trolley 71 exits the inspection room 62 and Stopped at the side.

The transfer-side self-propelled carriage 69 stopped at one side of the inspection device 60 moves the internal combustion engine 1 to the test device 60 and then exits again from the inspection room 62 to face the end of the supply conveyor 63. And stopped. Further, the internal combustion engine 1 on the unloading-side self-propelled carriage 71 stopped at the side of the unloading device 80 is conveyed by an eleventh conveyor 81 or the like. Then, the internal combustion engine 1 is transported to the next process by the twelfth conveyor 83.

In the above embodiment, the operator in the inspection room 62 checks the number of storages by visually checking the display unit 74. This is because a part of the enclosure 61 is made of transparent glass, and this transparent glass is made transparent. Then, the storage status on the supply conveyor 63 may be directly confirmed. In addition, one worker may be assigned to each of the two inspection rooms 62, or when a sliding door for passing through is provided in the middle partition 64, one worker may use one of the two inspection rooms.
Inspection at 62 may be concurrent. Note that, as a whole, the internal combustion engine 1
Is transported in a gate shape, but this can be changed in various ways such as being transported in a straight line.

[0030]

According to the present invention having the above structure, the warm-up device, the adjusting device, and the inspection device are arranged in a station form, and these devices are connected by the transport device, so that the remodeling work and the additional work can be performed easily and easily. It can be performed at low cost, and there are few restrictions on the automation equipment, so that it is possible to easily respond to automation. Further, it is possible to easily check the internal combustion engine from all directions with a small movement (walk).

Furthermore, since each device performs its own operation, each device itself can be made inexpensive and inexpensive even if the number of devices as a whole increases, and each device always functions. No waste and cost reduction. Furthermore, since each device performs its own performance test, the operator becomes a skilled expert, thereby improving the accuracy of the performance test.
