The link arm mechanism 39 includes a rotating arm 40 rotatably supported at the tip of the second arm 32.
And a pair of links 41, 41 rotatably supported on the distal end of the second arm 32. Thus, the rotating arm 40 is connected to both support plate portions 3 of the second arm 32.
It is arranged between 2a and 32b, and is rotatably supported on the tip of the second arm 32 by a horizontal shaft 42. The two links 41, 41 are rotatably supported by the shafts 43, 43 at the tip of the second arm 32 at a position different from the shaft 42. In addition, the rotating arm 40 and both links 41, 41
Are mounted on the mounting table 22 at different positions.
It is pin-connected by 45.

According to the link arm mechanism 39 described above, the mounting table 22 is moved to its lower position P _D and its upper position P _D.
It can be moved up and down while maintaining a horizontal posture with _U.

In order to move the link arm mechanism 39 up and down, a lift cylinder 4 is provided at the end of the second arm 32.
6 is clevis-supported, and the lifting cylinder 46 is connected to the rotating arm 40.

A cover 48 is provided on the floor 14 so as to cover the traveling carriage 20 in a reciprocating traveling range. One side of the cover 48 is connected to the first and second arms 30 and 32 by the traveling carriage 20. Is open to allow the projection to project to one side.

Next, the operation of this embodiment will be described. In assembling the damper 12 to the vehicle body B conveyed by the overhead conveyor 11, before the vehicle B is conveyed by the overhead conveyor 11, the traveling vehicle 20 The first and second arms 30, 32 are waiting at the original position at the rear end in the vehicle body transport direction 20, and the first and second arms 30, 32 are moved from the standby position in the posture along the longitudinal direction of the traveling vehicle 20 to the traveling vehicle 20.
Is rotated in synchronization with a projecting position projecting to one side.
At this time, the engaging member 21 is at the disengaged position, also the mounting table 22 is at the lowered position, one of the receiving members 47 _1, 47 ₂ on the support base 22, the damper 12 should assembled to the vehicle body B Is placed by a worker.

In this state, the overhead conveyor 11
When the vehicle body B is transported to a predetermined position close to the traveling vehicle 20, the engaging member 21 is rotated to the engaging position, and the mounting table 22 is raised to the raised position. When the hanger 18 of the overhead conveyor 11 moves, the engagement member 21 at the engagement position engages with the hanger 18, and thereafter, the traveling vehicle 20 moves the hanger 1.
8 and move in the vehicle body transport direction 10 in synchronization.

[0023] during the synchronous movement of such a vehicle body B, by the assembly of the vehicle body B of the damper 12 resting on support base 22 in the up position P _U worker performed while walking, Assembling of the damper 12 to the vehicle body B is completed. At the time of this assembly, the components of the assembly assisting device 13 are not located on the sides of the damper 12, so that the worker can easily assemble the damper 12 in an easy posture. The performance is also improved.

When the assembly of the damper 12 is completed, the engaging member 21 is lowered to the disengaged position and
8, the mounting table 22 is lowered to the lowering position P _D , and the first and second arms 30 and
32 is rotated to a standby position in which the carriage 32 takes a posture along the longitudinal direction. Next, by operating the traveling drive motor 28, the traveling carriage 20 can be returned to the original position. When the traveling vehicle 20 returns to the original position, the first and second arms 30, 32 do not protrude to one side of the traveling vehicle 20, so that the first and second arms 30, 32 are not protruded. It does not hit workers and is safe.

Although the embodiment of the present invention has been described in detail above, the present invention is not limited to the above embodiment, and various design changes can be made without departing from the present invention described in the appended claims. It is possible to do.
