Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an internal combustion engine test facility for performing a performance test on an internal combustion engine before it is installed in a vehicle body, for example, in an automobile assembly factory.

2. Description of the Related Art Normally, in an internal combustion engine test facility, an internal combustion engine is placed on a pallet, sent together with the pallet to a testing device, and after performing a desired performance test, the internal combustion engine is taken out together with the pallet.

Conventionally, as the internal combustion engine test equipment, for example, the turntable method shown in FIG. 4 and the in-line method shown in FIG. 5 have been provided. In the former turntable system, a plurality of test devices 31 are arranged on the turntable 30, and the internal combustion engine 33 conveyed by the main conveyor 32 is transferred to the carry-in conveyor.
The transfer device 35 on the carry-in side receives it via 34 and the like, and passes it from the transfer device 35 to the test device 31. The turntable 30 is for intermittent rotation.
A desired performance test is performed on the internal combustion engine 33 while the engine rotates almost once. Next, the internal combustion engine 33 is transferred to the transfer device 36 on the unloading side.
And is delivered to the main conveyor 32 via the carry-out conveyor 37. In the latter in-line method, the internal combustion engine 33 conveyed by the main conveyor 32 is passed on a trolley, and the trolley is run on the circulation path 38 while the test device 31 is provided on the side of the circulation path 38. hand over. Then, the internal combustion engine 33, for which the desired performance test has been completed, is taken out onto a trolley, the trolley is run on the circulation path 38, and then the internal combustion engine 33 is passed to the main conveyor 32.

Problems to be Solved by the Invention Among the above-mentioned conventional methods, in the former turntable method, the internal combustion engine 33 on the test apparatus 31 rotates and stops (intermittently) together with the turntable 30, so that performance is affected by the impact. The test is likely to be disturbed. In addition, since piping for fuel, cooling water, exhaust gas, etc. must be provided from the turntable 30 to the floor side, the structure becomes complicated, and a large pit for various piping is provided on the floor side. Must be formed. The problem of such a turntable system can be solved by the latter in-line system. However, in the in-line method, a large number of carriages are circulated and run in the same direction on the circulation path 38, which makes the control complicated. That is, when the internal combustion engine 33 is taken in and out of the test apparatus 31 at a certain position of the circulation path 38, the truck cannot be run upstream of the certain position, and the work at the certain position ends. Even when trying to drive the trolley, it is necessary to confirm whether or not work is being done in another place, so control becomes complicated and efficient work cannot be expected.

An object of the present invention is to provide an internal combustion engine test facility that can simplify the structure and control and can perform accurate and efficient tests.

Means for Solving the Problems In order to achieve the above-mentioned object, the internal combustion engine test equipment of the present invention is provided with a transfer device that is movable forward and backward on a certain circular path,
Outside the circular path, a carry-in device and a carry-out device of the internal combustion engine,
And a plurality of test devices, the transfer device,
The internal combustion engine is freely transferable between the carry-in device, the carry-out device, and the test device.

According to the configuration of the present invention, the internal combustion engine carried in by the carry-in device is received by the transfer device, and the transfer device is normally or reversely moved on the circular path, thereby making the target empty test device. Be opposed to. The internal combustion engine is then passed by the transfer device to the test device and undergoes the intended performance test. The empty transfer device faces the test device that has completed the performance test, stops, and then takes out the internal combustion engine, then moves forward or backward on the circular path to face the carry-out device, and passes the internal combustion engine to this carry-out device. .
