Turn on the movement in the X direction/017F.

Next, the operation of the board pasting device 1 having the above-mentioned structure will be explained as shown in FIG. A case in which a rectangular board B is pasted to a corner of the board B will be explained step by step.

■First, the ceiling '1 where you are going to paste board B.
Move device I below . Then, the eleventh second arm 14.15 of the lifting mechanism 5 is lowered, and the second
The board holder 6 fixed to the first slide plate 30 of the pedestal 7 is tilted slightly as shown in FIG. 1 by rotating the bracket 21 attached to the arm 15. The board B housed in the board carrier 4 is placed on the board carrier 4.

(2) First, the first arm 14 is extended by the elevating mechanism 5, and then the bracket 21 is rotated upward to make the slide shaft 22 upright, and the pedestal 7 and board B are made approximately horizontal. Subsequently, the second arm 15 is raised and the board B is pressed against the ceiling T. At this time, even if the ceiling T is not horizontal but sloped, as shown in FIGS. The board B is tilted against the force of 26, and the board B is pressed tightly against the ceiling T.

When the board B is pressed against the ceiling T in this way, the slide shaft 22 is pushed downward and descends, and when the lever 39a is removed from the circumferential groove 22b (see FIG. 5), the lifting mechanism 5
The lifting operation stops. At this time, the board B is kept pressed against the ceiling'' by the push-up spring 25 on the outer periphery of the slide shaft 22.The arrangement of the board B with respect to the ceiling surface at this point is shown in FIG. 8a.

Next, the moving mechanism 8 moves the elevating mechanism 5 in the X direction as shown in FIG. As a result, the board B moves in the X direction, and the corner of the board B comes into contact with one wall surface Wl, and using this as a fulcrum, the board B rotates together with the slide shaft 22, and the long side end surface comes into contact with the wall surface W1. This causes the rotation to stop. At this point, the board B is arranged parallel to the wall surface Wl, as shown in FIG. 8c.

From this state, the moving mechanism 8 further operates to press the board B in the X direction, so that the first sliding plate 30 is fixed, and the fixed plate 24 and the second sliding plate 28 are moved together with the lifting mechanism 5. It slides in the X direction against the force of the regulating spring 38 between the slide plates 28 and 30.

When these slide a predetermined distance, the lever 43a of the microswitch 43 fixed to the first slide plate 30 is tilted so as to come into contact with the small diameter portion 42b of the cylindrical cam 42, and the lifting mechanism 5 is actuated in the X direction. The operation of the moving mechanism 8 that is being moved is stopped. At this time, the board I3 is pressed against the wall surface W1 by the regulating spring 38.

(2) Subsequently, the moving mechanism 8 moves the lifting mechanism 5 in the X direction as shown in FIG. 8C. As a result, the board B moves in the X direction, and the end surface of the short side of the board B comes into contact with the wall surface W on the other side, and the movement of the board B is stopped.

From this state, the moving mechanism 8 operates to further press the board I3 in the slides in the X direction against the force of the regulating spring 34 between the slide plates 28.

When these slide a predetermined distance, the fixed plate 24
Micro switch 4 fixed on! lever 41a
is tilted so as to contact /IOb with the small diameter portion of the cylindrical cam 40, and the operation of the moving mechanism 8 that operates the elevating mechanism 5 in the X direction is stopped. At this time, the board B is pressed against the wall surface W by the regulating spring 34.

As a result, the board B is positioned at the corner of the ceiling 1'' as shown in FIG. 8d, and the board B is temporarily attached. The flow of the above operation is shown in FIG. 8a to d.

Thereafter, a worker gets on the workbench 3 fixed to the trolley 2, screws the board B to the ceiling 'r, and completes the work of pasting one board B. After completing this screw fixing work, lower the pedestal 7 using the lifting mechanism 5, and then
By returning the elevating mechanism 5 to its original position on the bottom of the trolley 2 by 8, the bracket 21 is lowered by the push-up spring 25, and both slide plates 28, 30 are returned to their original positions by the regulating springs 34, 38, respectively. Then, the pedestal 7 and the fixing plate 24 return to their normal positions.

By repeating the above operations, a large number of boards 13 can be attached to the ceiling 'r.

In this case, when board B does not come into contact with wall surface W1 or W, and board B is pasted on the inside thereof, board B that has already been pasted takes the place of wall surface W1, W, and its position is restricted. It will be done.

Note that when the bracket 21 is held horizontally, the pedestal 7 is placed on the wall surface W+,
W...! : If they are made parallel, these wall surfaces W3,
Board B can also be attached to W.

According to the above-mentioned board pasting device 1, the work of holding board B up to the ceiling and positioning it is automated, which reduces the burden on workers and avoids danger, thereby shortening work time and improving work efficiency. , significantly improved. Furthermore, the assembly and disassembly work of the work scaffold, which conventionally occupies a part of the entire board pasting work, is no longer necessary, which also shortens the work time.

Furthermore, board B is positioned relative to the ceiling or wall by a combination of the slide shaft 22, both slide plates 28.30, push-up spring 25, regulation spring 34.38, each micro switch 39.41.43, etc. It has a simple structure and does not require complicated calculations or control, so it can be manufactured at low cost and downsized. In addition, the push-up spring 25 and regulating springs 34 and 38 that hold the board B in a positioned state act on the board B with appropriate force, so that the lifting mechanism 5, the moving mechanism 8, and even the board B are not damaged. .

[Effects of the Invention] As explained above, the board pasting device of the present invention eliminates the need for assembling and dismantling work scaffolds, which conventionally occupied a part of the entire board pasting work, and also eliminates the need for assembling and dismantling work scaffolds, which conventionally occupied a part of the entire board pasting work, and Since it automates the work of lifting and positioning, it reduces the burden on workers and avoids danger, thereby shortening work time and greatly improving work efficiency.
