21 protrudes higher than the glass plate supporting surface, and moves forward until it can support the glass plate.

This state is the state shown in FIGS. 2 and 7. From this state, as shown in FIG.
1 and 21 and slightly tilted toward the work table 22 side, the glass plate A is suction-supported by the vacuum pads 50 and 50, and set on the work table 22 via the glass plate support protrusion 53.

In this way, since the glass plate A is suction-supported by the vacuum pads 50, 50 with the work table 22 in the upright position, it becomes easy to set the glass plate A on the work table 22.

Next, as shown in FIG. 8, the second foot switch F2 is stepped on to extend the movable rod 6a of the vertical cylinder 6 to raise the upper movable body 3, and the fifth foot switch F is stepped on to extend the movable rod 17a of the horizontal cylinder 17. The oscillating body 13 is retracted and the oscillating body 13 is swung clockwise to bring the work table 22 into an inverted position (approximately horizontal position), and the movable rod 20a of the cylinder 20 is retracted to lower the support 21 below the glass plate A. position.

Next, as shown in FIG. 9, a gasket B is mounted around the glass plate A using a gasket mounting jig C.

At this time, after attaching the gasket B to one end edge of the glass plate A, step on the first foot switch F1 to energize the solenoid 42 shown in FIG.
1 against the spring 43 and move the swing stopper 40 into the positioning groove 3.
9, the work table 22 is rotated 90 degrees within the plane of the work table via the rotating shaft 25, and the gasket B is successively attached to the next edge of the glass plate.

Note that when the work table 22 rotates 90 degrees, the moving rod 45
is pushed down, the microswitch 44 is turned off, the solenoid 42 is demagnetized, and the swinging lever 41 is swung by the spring 43 so that the stopper 40 fits into the positioning groove 39 and is stopped in position. In this way, by rotating the work table 22 every 90 degrees with the work table 22 in a substantially horizontal position, the gaskets B can be sequentially and continuously attached to each peripheral edge of the glass plate A, so the operator does not have to move and can attach the gaskets. The work becomes easy and the work can be done safely because the glass plate A is supported by the work table 22 via the vacuum pad 50 and does not move slightly. Next, the stile D is attached in the same manner as described above, and then the stile D and D are connected to each other with screws to assemble the shoji.

Even if the glass plate A tries to move when attaching the frame D, it hits the stopper 71 and does not move.

Note that this stopper 71 may not be necessary depending on the suction force of the vacuum pad 50.

After assembling the shoji, turn the select switch S (7) 0FF on the front of the vacuum pad 50 to weaken the suction force.
As shown in the figure, the shoji is lifted and pushed along the pair of plate glass moving rollers 51, 51, and then the foot switch F4 is stepped on and the movable rod 20a of the cylinder 20 is extended in conjunction with the raising of the work table to move the support body 21. raise.

That is, the operations of the cylinders 17 and 20 are controlled to be electrically interlocked. Thereafter, in the same manner as described above, the movable rods 6a and 17a of the vertical cylinder 6 and the horizontal cylinder 17 are extended and contracted to lower the upper movable body 3 and place the work table 22 in the upright position.

As a result, the stile D of the shoji is moved in the direction away from the support 21, so the stile D can swing to a standing position without interfering with the pair of supports 21, 21, and then the vacuum pad 50 It is okay to release the suction force and remove the shoji.

Further, since the work table 22 can be removed from the rocking body 13 by loosening the butterfly bolt 38, work tables 22 of different shapes and sizes can be replaced.

For example, as shown in FIG. 11, when assembling a shoji with a middle crosspiece E, a work table 22 having a structure having a pair of middle crosspiece supports 90, 90 may be attached at the middle part in the width direction.

Further, on both sides of the lower fixed body 2, a pair of auxiliary supports 55,
55 is a pair of supports 21, 2 that can move toward each other and move away from each other.
1, it is safe because it prevents accidents such as the glass plates and shoji from tilting and falling when setting and removing large glass plates and shoji on the work table 22. be.

Further, reference numeral 100 shown in FIGS. 11 and 12 is a support arm provided at the lower left and right ends of the work table when assembling a shoji with a middle crosspiece, and is paired with the supports 21 and 21. This serves as a support for the glass plate.

Note that the support arm 100 can be erected and inverted using the fixed shaft 101 as a fulcrum, and is kept in the inverted position when attaching the gasket and the stile.

With the present invention as described above, with the work table 22 in an upright position, the suction support set of the glass plate A to the vacuum pad 50 and the assembled shoji can be removed, making it easy to set the glass plate A and remove the shoji. .

In addition, since the work table 22 can be rotated within its plane in an inverted position, the operator can rotate the glass plate A and attach the gasket B and the stile D, as well as fasten them with screws, without having to move. Work becomes easier.

Further, since the glass plate A is suction-supported by the vacuum pad 50, the glass plate A does not move during the gasket installation work, the stile installation work, and the screw fastening work, making it possible to work safely.

Further, the support 21 is attached to the movable rod 20a of the cylinder 20 so that it is located below the lower side of the work table 22 when the work table 13 is erected, and protrudes from the front surface of the work table 22 when the movable rod 20a is extended or contracted. Since the support body 21 can be moved in and out from the sunken position, the glass plate can be supported by placing the support body 21 in the protruding position. 21 to a position recessed from the front surface of the work table 22, the glass and the support 21 will not interfere with each other when the work table 22 is rotated.
Since it is separate from the work table 22, it is only necessary to rotate the work table 22, and the work table 22 can be rotated with a light force.
