The operation of the above embodiment will be described below. In the ceiling-side transfer device 1, the trolley device 4 supporting the vehicle body A moves by receiving the moving force from the chain type drive device 10 and thus transfers the vehicle body A on the upper transfer line 6 at a predetermined speed. is doing. In the floor-side transfer device 40, the drive wheels 45 are forcibly rotated by the electric power of the battery 50 via the travel drive device 47, whereby the self-propelled carriage 43 can automatically travel on the lower transfer line 52.

At this time, when the detection device 42 detects the dielectric 41 and the position of the detection device 42 is about to be displaced with respect to the dielectric 41, the control panel 49 sends a forward or reverse command to the turning drive device 48. Then, the self-propelled carriage 43 can be automatically traveled on the lower conveyance line 52 while automatically correcting the displacement of the self-propelled carriage 43.

The self-propelled carriage 43 that supports the internal combustion engine B is stopped by the standby unit 96. At this time, in the self-propelled carriage 43, the upper lift 63 is lowered with respect to the lower lift 61 by the lowering movement of the upper lifter 62, and this lowering causes the fitted member 77 to the fitting member 76 with respect to the fitting member 76.

In such a state, the self-propelled carriage 43 waiting in the waiting portion 96 is automatically driven again when the trolley device 4 reaches a predetermined position on the upper transfer line 6, and enters the built-in working portion 53. go. Then, as shown by the solid lines in FIGS. 1 and 2, the self-propelled carriage 43 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 6. Run synchronously.

At this time, the moving speed on the trolley device 4 side is detected by the speed detecting device 20, and a speed control signal is wirelessly (radio wave) emitted from the transmitter 33 to the receiver 58 based on the detected value. That is, the trolley device 4 moves integrally with the drive chain 13, and the amount of movement of the drive chain 13 is the driven chain wheel 11, the driven shaft 17, the large diameter chain wheel 29, and the interlocking chain.
31. The rotation speed of the primary shaft 24 is taken out via the small diameter chain wheel 30 and transmitted to the secondary shaft 25 via the large diameter gear 26 and the small diameter gear 27 to operate the encoder 28.

The operation signal of the encoder 28 is converted into the conversion device 32.

A worker is attached to 43 and walks in synchronization with the synchronized driving. During this walking, the operator operates the elevating lever 90, and the elevating movement of the lower elevating / lowering device 60 causes the lower elevating body to move against the main body 44.
61 is lifted, and the upper lifting / lowering device 62 is lifted with respect to the lower lifting / lowering body 61 by the lifting motion of the upper / lower lifting / lowering device 62. Both of the lock mechanisms 74, 84 are lifted by raising the upper lifting body 63.
Is automatically unlocked.

The above-described upper elevating body 63 is raised little by little, during which the operator makes a 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 can be performed by moving the lower slide plate 71 left and right with respect to the upper lift 63 due to the allowable structure of the left-right guide device 70. The permissible structure of the device 80 allows the upper slide plate 81 to move back and forth with respect to the lower slide plate 71.

In this way, the internal combustion engine B whose position has been corrected with respect to the vehicle body A is incorporated into the vehicle body A from below as shown by the phantom lines in FIGS. Fixed work is performed. When the fixing work is performed, the components in the component receiver 51 are used. Then, the worker who finishes the fixing operation operates the elevating lever 90 in the reverse manner to the above, and the lower elevating / lowering device 60 descends to lower the elevating body with respect to the main body 44.
While lowering 61, the upper elevating body 63 is lowered with respect to the lower elevating body 61 by the lowering movement of the upper elevating device 62. The lowering of the upper lifting / lowering body 63 causes both locking mechanisms 74, 84.
Is automatically locked.

Further, the worker pushes the work completion button 91 together with the reverse operation of the elevating lever 90. As a result, the locking mechanism 74, 84
The work is completely completed in a state in which the lock motion of is confirmed, and the self-propelled carriage 43 automatically travels on the lower transport line 52 at a high speed and stops at one of the stations 94 and 95. 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 89. This loading is stable and reliable because both slide plates 71 and 81 are in a lock shape.

When stopped, the collector 56 is a charging device.
The battery 50 is automatically contacted with 99 to be charged, and the air coupler of the air replenishing device 98 is connected to the air coupler 93 of the air unit 92 to replenish the accumulator of the air unit 92 with air. Self-propelled trolley 43
Automatically travels again on the lower transport line 52 at high speed,
At 96, it stops and waits. As described above, the self-propelled carriage 43 traveling on the lower conveyance line 52 wirelessly exchanges information with the ID tag 97 to confirm seating.

When the stations 94 and 95 are provided at two locations (plural locations) as shown in the above embodiment, the self-propelled carriage is used.
There is sufficient downtime at 43 stations 94, 95, but this may be at one location. Further, in the above embodiment, a guide magnet is shown as the inductor 41, 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 42.
