The receiving frame switching device 7 is installed, for example, on the side of the transport line as shown in FIG. That is, in FIG. 7, reference numeral 16 denotes an assembly work line, A denotes a vehicle body transfer position, and B denotes a vehicle body unloading position. Reference numeral 17 denotes a return line for an empty truck parallel to the assembly operation line 16. Reference numerals 18 and 19 denote communication paths between the assembly work line 16 and the return line 17.
Then return the empty truck from the vehicle unloading position b Return line 17
, And the connecting line 19 introduces the bogie from the reply line 17 to the vehicle carrying-in position a.

The receiving frame switching device 7 is connected to one of the communication paths 18 and 19.
Is provided, and the vehicle type receiving stage is switched to the vehicle body receiving frames 3a to 3d according to the vehicle body to be carried into the vehicle body carrying position a.

Next, the switching operation of the vehicle body receiving pieces 3a to 3d will be described with reference to FIGS.
The switching between the vehicle body receiving pieces 3a and 3b will be described as an example with reference to the drawings.

First, the vehicle body receiving piece 3a used in the previous mounting on the vehicle body is set to the non-use position sideways posture. As shown in FIGS. 4 (A) and 5, the third cylinder 13 is slid by the second cylinder 12 to position the third cylinder 13 at a position corresponding to the vehicle body receiving piece 3a. The support 8 is located at the lowermost end. Thereby, the piston rod of the third cylinder 13
The fourteen end rollers 15 correspond to the lower end side surface of the standing vehicle body receiving piece 3a. In this state, the third cylinder 13 is operated to move the piston rod 14 forward, so that the lower end side surface of the vehicle body receiving piece 3a is moved to the piston rod 14 as shown in FIG.
Is pushed through the roller 15, so that the vehicle body receiving piece 3a is
Turns to the receiving frame switching device 7 side with
After turning 90 °, it comes into contact with the stopper 6 to maintain the sideways posture.

Next, the vehicle body receiving piece 3b to be used is set to the standing posture. This means that the piston rod 14 of the third cylinder 13 with the vehicle body receiving piece 3a turned over is returned to the retracted end, and the slide base 11 is moved and positioned by the second cylinder 12 so that the piston rod 14 corresponds to the vehicle body receiving piece 3b. . As a result, as shown in FIG. 6A, the roller 15 of the piston rod 14 comes into contact with the upper end side surface of the vehicle body receiving piece 3b in the sideways posture. In this state, when the first cylinder 10 is operated to move the support base 8 upward, the roller 15 lifts and turns the vehicle body receiving piece 3b as shown in FIG. 6 (B), and hits the stopper 6 beyond the dead point. Then, the vehicle body receiving piece 3b comes to the standing position in the use position.

The vehicle body receiving frames 3a to 3d required in the manner described above are switched by the vehicle type switching stage 20. The selection of the vehicle body receiving frames 3a to 3d is performed by previously detecting the vehicle type at the time when the bogie 2 is introduced to the vehicle carrying-in position A, and transmitting the signal to the vehicle type switching stage 20.
