The first station 65, the second station 66, and the standby section 67 are arranged in this order in the line portion from the end to the start of the built-in working section 23, and further at a plurality of locations on the floor 8 side. An ID tag 68 is provided.

Both stations 65 and 66 are formed in the loading portion of the internal combustion engine B, and have an air supply device 69 and a charging device 70.
Is provided. The air supply device 69 is, for example, an air generating device such as a compressor, an air coupler attached to the tip of a hose from the air generating device and connectable to the air coupler 64 in a male and female manner, and a cylinder for connecting and disconnecting the air coupler. The charging device 70 is of a rail type so that the collector 26 can be contacted from above.

The operation of the above embodiment will be described below. In the suspending and conveying apparatus 1, the trolley device 4 supporting the vehicle body A moves by receiving the moving force from the drive device 6, so that the vehicle body A is moved on the upper conveying line 7 at a predetermined speed (constant speed). It is transported in. Further, in the carriage transportation device 10, the drive wheels 15 are forcibly driven by the electric power of the battery 20 via the travel driving device 17, whereby the self-propelled carriage 13 can automatically travel on the lower transportation line 22.

At this time, when the detecting device 12 detects the dielectric 11 and the position of the detecting device 12 is about to be displaced with respect to the dielectric 11, the control panel 19 issues a forward or reverse command to the turning drive device 18. Thus, the self-propelled carriage 13 can be automatically traveled on the lower transport line 22 while automatically correcting the positional deviation of the self-propelled carriage 13.

The self-propelled carriage 13 supporting the internal combustion engine B is stopped by the standby portion 67. At this time, in the self-propelled carriage 13, the upper elevating body 33 is descending with respect to the lower elevating body 31 due to the lowering movement of the upper elevating device 32, and due to this lowering, the fitted member 47 with respect to the fitting member 46. By fitting from above, the horizontal position of the lower slide plate 41 with respect to the upper elevating body 33 is corrected to the central portion, and the corrected position is locked. Further, by fitting the fitted member 57 to the fitting member 56 from above, the position of the upper slide plate 51 with respect to the lower slide plate 41 in the front-rear direction is corrected to the central portion, and
The correction position is locked.

In such a state, the self-propelled carriage 13 waiting in the waiting portion 67 is automatically driven again when the trolley device 4 reaches a predetermined position on the upper transfer line 7, and enters the built-in working portion 23. go. As shown by the solid lines in FIGS. 1 and 2, the self-propelled carriage 13 is mounted on the trolley device 4 side in a state where the internal combustion engine B is opposed to a predetermined position of the vehicle body A which has been conveyed through the upper conveyance line 7. Run synchronously.

In this built-in working unit 23, a self-propelled carriage
A worker is attached to 13 and walks according to the synchronized running. During this walking, the operator operates the elevating lever 61 to move the lower elevating / lowering device 30 up and down so that the lower elevating body is moved relative to the main body 14.
31 is lifted, and the upper lifting / lowering device 32 is lifted with respect to the lower lifting / lowering member 31 by the lifting motion of the upper / lower lifting / lowering device 32. Both of the lock mechanisms 44, 54 are lifted by raising the upper lifting body 33.
Is automatically unlocked.

The above-mentioned upper elevating body 33 is raised little by little, during which the worker performs the final position correction of the internal combustion engine B with respect to the vehicle body A. That is, the worker applies a force to the internal combustion engine B in the position correcting direction. As a result, position correction in the left-right direction is made possible by the horizontal structure of the lower slide plate 41 relative to the upper lift 33 due to the allowable structure of the left-right guide device 40. The permissible structure of the device 50 allows the upper slide plate 51 to move back and forth with respect to the lower slide plate 41.

In this way, the internal combustion engine B whose position has been corrected with respect to the vehicle body A is incorporated from below into the vehicle body A as shown by the phantom lines in FIGS. Fixed work is performed. When this fixing work is performed, the components in the component receiver 21 are used. After the fixing work, the operator operates the elevating lever 61 in the opposite manner to the above, and the lowering of the lower elevating / lowering device 30 causes the lower elevating / lowering body to move against the main body 14.
While lowering 31 the lower lifting body 31 lowers the upper lifting body 33 by the lowering movement of the upper lifting device 32. The lowering of the upper lift 33 causes both locking mechanisms 44, 54
Is automatically locked.

Further, the worker pushes the work completion button 62 together with the reverse operation of the elevating lever 61. As a result, the lock mechanism 44, 54
The work is completely completed in a state in which the locking movement of the vehicle is confirmed, and the self-propelled carriage 13 automatically travels on the lower transport line 22 at a high speed and stops at one of the stations 65 and 66. At the time of this stop, the support part is operated by the operation of the loading device or manually.
A new internal combustion engine B is loaded into 60. This loading is stable and reliable because both slide plates 41 and 51 are in a lock shape.

Further, when stopped, the collector 26 is a charging device.
The battery 20 is automatically charged by making contact with 70, and the air coupler of the air replenishing device 69 is connected to the air coupler 64 of the air unit 63 to replenish the accumulator of the air unit 63 with air. Then, the self-propelled carriage 13 automatically travels on the lower transport line 22 again at high speed,
The standby unit 67 temporarily stops and stands by. As described above, the self-propelled carriage 13 traveling on the lower conveyance line 22 wirelessly exchanges information with the ID tag 68 to confirm the presence of the seat.

When the stations 65 and 66 are provided at two locations (plural locations) as shown in the above embodiment, the self-propelled carriage
Sufficient downtime at 13 stations 65 and 66, but this may be at one location. Further, in the above-mentioned embodiment, the guide magnet is shown as the derivative 11, but this may be a magnetic tape or the like, and in the case of a magnetic tape, a pickup coil is used as the detection device 12.

In the above-mentioned embodiment, the left and right guide devices 40 and the front and rear guide devices 50 constitute a plane movement allowance device.
This plane movement allowance device may have a structure including movement in the direction of rotation in plan view. Further, in the above embodiment, the vehicle body A is used as the first member and the internal combustion engine B is used as the second member.
However, this can be used for assembling other members.
