Thus, the expansion device 7 is attached to the first slider 2a via the bracket 5 and the support plate 6, while the pushing device 9 is attached to the second slider 2b via the bracket 8. A detection device 11 is attached via a bracket 8 and a support plate 10.

The expansion device 7 also has a support plate 6 at the output shaft end of a cylinder 7a fixed to the support plate 6.
The base of the arm 7b is connected to the base of the arm 7b, which is pivotally attached to the arm 7b, and the tip of the swinging arm 7b directly expands the main body, which will be described later. The pushing device 9 has a V block 9b attached to the output shaft end of a cylinder 9a fixed to the bracket 8, and serves to push the roof panel into the body body, which will be described later. Further, the detection device 11 includes a pair of arms 11a, 11a pivotally connected to the support plate 10 so as to be able to open and close with respect to each other, a cylinder 11b bridged between the bases of the pair of arms 11a, 11a, and a base of the one arm 11a. It consists of limit switches 11c, 11c disposed on the side rear support plate 10, and a movable dog 11d disposed at the base of one arm 11a so as to be able to engage with the limit switch 11c, The tips of the pair of arms 11a, 11a sandwich the joint between the body main body and the roof panel, which will be described later, and detect the floating state of the roof panel at this time based on the degree of engagement between the limit switch 11c and the dog 11d. Eggplant. Note that the expansion device 7, the pushing device 9, and the detection device 11 are arranged at appropriate intervals in the direction perpendicular to the plane of the paper, so that they do not interfere with each other.

With this configuration, the expanding device 7, the pushing device 9, and the detecting device 11 are initially placed on standby at the rear (to the right in the figure) during use. and now,
When the body main body 1' and the roof panel 2', which have a drip channel 3' on the side of the frame 1, are transported, the first and second cylinders 4a and 4b are activated, and the first and second The sliders 2a and 2b move forward toward the main body 1' as indicated by arrows A and B, respectively, and the respective devices operate at predetermined timings. Hereinafter, a method for setting the roof panel will be explained based on FIGS. 4 and 5, which are schematically shown.

First, as shown in FIG. 4, the cylinder 7a of the expansion device 7 is actuated to swing the arm 7b in the direction of arrow C, and the tip of the arm 7b touches the main body 1'.
is extended from the dashed line position to the solid line position within the elastic deformation limit. As a result, the drip channel 3', which has been in a negative angle position, becomes an upright position, and the roof panel 2' is inserted into the body body 1' in this state from above in the direction of arrow D by a conveying device (not shown). be done.

Subsequently, as shown in FIG.
The cylinder 9a operates to bring the V block 9b at its tip into contact with the shoulder of the roof panel 2', and then push the edge of the roof panel 2' into the drip channel 3' as shown by arrow E. . At almost the same time, the cylinder 11 of the detection device 11
b is activated to rotate the arm 11a from the chain line position to the solid line position in the closing direction as indicated by the arrow F, thereby sandwiching the body main body 1' and the roof panel 2' within the drip channel 3'. As a result, the roof panel 2' is further pushed into a stable position.
At this time, if there is no abnormality in the set state, arm 1
The dog 11d provided at the base end of the roof panel 1a engages with the limit switch 11c, confirming that it is in good condition.On the other hand, when the roof panel 2' is in a lifted state, the dog 11d engages with the limit switch 11c.
Since it does not engage, it is confirmed that the setting is defective. The confirmation method is by using a lamp, an alarm, etc. (not shown).

Here, all the operations of the above-mentioned devices are performed automatically, and almost unmanned operation can be achieved.

In the above embodiment, the two sliders 2a and 2b which are driven separately are provided, but instead of this, the expansion device 7, the pushing device 9, and the detection device 11 are attached to one slider all at once.
