Next, the structure of the stopper device 51 will be described with reference to FIG.

The stopper device 51 is provided on the floor F on which the door transport cart C travels, and includes a stopper 54 supported by a bearing 52 disposed below the floor F via a support shaft 53 so as to be swingable. . Output rod 56 ₁ of the cylinder 56 which is supported a tail end on a bracket 55 provided on the lower surface of the floor F is coupled to the lower end of the stopper 54,
By driving the cylinder 56 to expand and contract, the upper part of the stopper 54 that projects upward through the opening 57 of the floor F swings. A first stopper surface 54 ₁ and a second stopper surface 54 _{2 that} intersect at an angle α are provided above the stopper 54.
There are formed, these first stopper surface 54 ₁ and the second stopper surface 54 ₂ is engageable with the edge portion 2 ₁ of the opposite side of the handle 3 of the truck body 2 (see FIGS. 1 and 3).

Next, the operation of the embodiment of the present invention having the above-described configuration will be described.

The lower end of the rear right door D is supported by a pair of front and rear lower end support means 29, 29 provided on the floating table 28 of the door carrier trolley C, and is provided at the upper end of a support arm 30 erected on the floating table 28. By adsorbing and supporting the inner surface of the window glass of the door D on the suction pad 43, the door D is mounted on the door carrier C in an upright posture. At this time, the index plunger 36 of the suction pad support means 31 is loosened to change the angle of the adjustment link member 34 with respect to the bracket 32, and the index plunger 41 is loosened to change the angle of the support block 39 with respect to the adjustment link member 34. By making changes,
The left and right position, the up and down position, and the angle of the suction pad 43 can be adjusted to suit different models.

Subsequently, as shown in FIG. 7, the door carrier C supporting the rear right door D is approached from the right rear to the vehicle body B of the vehicle positioned on the vehicle assembly line, and is roughly positioned. I do. Specifically, the operator presses the handle 3 moves the door conveyance carriage C, the edges of the truck body 2 to the first stopper surface 54 ₁ of the stopper 54 of the stopper 51 standing upright at the position indicated by the solid line in FIG. 6 2 Make ₁ abut. Subsequently, by sliding the vehicle body B side along the edge 2 ₁ of the carriage body 2 to ₁ the first stopper surface 54, front leading edge of the door D mounted on the door conveyance carriage C is a door mounting opening of the vehicle body B Roughly positioned to match the edge.

Subsequently, the cylinder 15 is driven to extend and contract to reduce the height of the door D so that the position of the hinge provided at the front edge of the door D matches the position of the hinge provided at the front edge of the door mounting opening. Adjust the sliders 6 against the guide rails 4 and 4.
6 is manually adjusted to finely adjust the position of the door D to the left and right.
The swinging angle of the door D is finely adjusted by manually swinging the floating table 28 floatingly supported by 25, and the floating table 28 is manually slid with respect to the guide rails 12 and 12 to adjust the position of the door D. By finely adjusting the front and rear, and further compressing the coil spring 46 to move the position of the suction pad 43 in a direction perpendicular to the suction surface and finely adjusting the right and left swing angle of the door D, And joined together.

As described above, the door D is supported on the door carrier trolley C so that the position of the door D can be adjusted.
It is possible to easily and quickly perform the work of assembling the device, thereby improving workability. In particular, since the left and right movements of the sliders 6 and 6, the swinging movement of the swing frame 22, the forward and backward movement of the floating table 28, and the forward and backward movement of the suction pad 43 in the direction of the rod 42 are performed by the floating support, a slight external force is applied. The position and posture of the door D can be finely adjusted. In addition to assembling the door D to the vehicle body B, it is possible to perform the operation of removing the door D from the vehicle body B by using the door carrier trolley C of this embodiment.

In FIG. 6, when the cylinder 56 is driven to contract to raise the stopper 54 from the solid line position to the chain line position, the second stopper surface 54 ₂ having a different position relative to the vehicle body B is used instead of the first stopper surface 54 _1. There will be contactable with the edge portion 2 ₁ of the carriage body 2, the positions of the door mounting opening of the vehicle body B correspond to slightly different model.

The attachment / detachment of the rear right door D of the automobile has been described above, but the attachment / detachment of the rear left door, the front right door, and the front left door can be similarly performed (see FIG. 7).

Although the embodiments of the present invention have been described in detail above, the present invention is not limited to the above embodiments, and various design changes can be made.

For example, in the embodiment, the door D is connected to the cylinder 15
However, the door D may be floatingly supported by a spring or the like capable of supporting the weight of the door D so as to be able to move up and down freely.

[0032]

As described above, according to the first aspect of the present invention, the lower end supporting means provided on the floating table which is floatingly supported on the bogie main body so as to be movable left and right, movable back and forth and tilted forward and backward. In addition to supporting the lower end of the door, the suction pad, which is supported by the floating table so as to be position-adjustable and sucks the upper part of the door, is floatingly supported so as to be movable in the vertical direction with respect to the suction surface. Can be finely adjusted in any direction to easily and precisely position the door with respect to the door mounting opening of the vehicle body, and the attaching and detaching operation can be performed efficiently.

According to the second aspect of the present invention,
Since the stopper projecting upward from the floor is brought into contact with the linear edge of the bogie main body of the door transport bogie and stopped at a predetermined position, rough positioning of the door transport bogie can be performed with a simple structure. In addition, since the door supported by the door carrier is positioned in the door mounting opening of the vehicle body in an open state, workability in attaching and detaching the door is improved.

According to the third aspect of the present invention,
By changing the position of the stopper to a different position with respect to the vehicle body, the same door carrier can be applied to a plurality of models having different positions of the door mounting openings, and versatility is improved.
