As a result, the hook member 12 contacts the rear end portion of the assembly carriage 4 and pushes the assembly carriage 4 along the guide groove 11 to move the assembly carriage 4. Then, the empty assembly carriage 4 that has been transported through the second transport line 2 is transported toward the first transport line 1. At this time, the toe pin 6 provided on the assembly carriage 4 is guided by the guide groove 11
The trolley 4 is smoothly guided by the guide. Then, it is smoothly supplied to the first transfer line 1.

As shown in FIG. 3, when the assembly carriage is transferred from the connection line 10 to the first transfer line 1, the transfer of the assembly carriage 4 by the connection line 10 is limited to the first transfer line 1. The switch is controlled at a predetermined interval, and in the first transfer line 1,
When the preceding assembling carriage 4 passes through the detection part of the limit switch, the hook member 12 of the connecting line 10 is actuated, and the following assembling carriage 4 is propelled. Further, the movement of the subsequent assembling carriage 4 is temporarily stopped and waits at the loading end of the first transport line 1 until the preceding assembling carriage 4 passes through the detection section of the limit switch. . In this way, the loading of the assembly carriage 4 to the first transport line 1 is performed at a predetermined transport pitch that is arbitrarily set in the first transport line 1.

In the above embodiment, the hook member 12 is engaged with the assembly carriage 4 in the connecting line 10 so that the assembly carriage 4 is pushed to run, but the hook member 12 is engaged with the assembly carriage 4. Alternatively, the assembly carriage 4 may be pulled.
