The balance circuit 6 as described above when tilted to the balance side.
The pressure (P1) on the balance cylinder 20 side of the pilot type pressure reducing valve 46 of B becomes equal to the comparative enclosed pressure (P0), and the position of the plunger 21 of the balance cylinder 20 is maintained and the balance state is achieved. In this state, the work 1 is transferred to the building unit 8 at the transfer target position. Further, at this time, the above-described ascending limit SW 24 is turned on, the signal thereof is transmitted to the control unit of the safety device, and the driving state of the press-fitting cylinder device 14 is held based on the signal from the control unit. The work 1 is prevented from falling off due to an erroneous operation. Therefore, the worker can concentrate on the mounting work without anxiety.

Then, as shown in FIG. 9, the worker 9 goes around to the side opposite to the control panel 17 having the switch part, and attaches the work 1 or the hinge piece 1a of the entrance door to the hinge of the entrance / exit of the building unit 8. The work 1 is attached by engaging the piece 8a. In this case, as shown in FIG.
By using 0, the work 1 can be easily attached to the entrance / exit of the building unit 8.

Now, the auxiliary tool 70 will be described with reference to FIGS. 10 and 11. Auxiliary tool 70 is pivot pin 8
The female hinge piece (the hinge piece) in which the insertion hole 1d for inserting the pivot pin 8b from the lower side is formed in the male hinge piece (the hinge piece 8a) attached to the building unit 8 side with b facing upward. It is an auxiliary tool for assembling the piece 1a) into a hinge, in which the inner diameter of the bottomed tubular main body 71 whose upper part is closed is set larger than the outer diameter of the hinge portion 1b of the hinge piece 1a, A notch 72 is formed in the peripheral wall portion of the main body 71 for loosely fitting the sleeve sleeve 1c for attachment connected to the hinge portion 1b in the vertical direction, and the height of the peripheral wall portion of the main body 71 is set longer than the height of the hinge portion 1b. It has a structure. Further, the opening of the auxiliary tool 70 is provided with a taper 73 that widens toward the opening side.

In order to attach the entrance door 1 to the entrance of the building unit 8 using the auxiliary tool 70 thus constructed,

The door 1 is inserted into the hinge pin 1b of the hinge piece 1a with respect to the pivot pin 8b of each hinge piece 8a.
While vertically facing each other, the door 1 is lowered in a vertical state, and each pivot pin 8b is inserted into each insertion hole 1d. At this time, the main body 7 of the auxiliary tool 70
Since the inner diameter of 1 is set to be larger than the outer diameter of the hinge portion 1b of the hinge piece 1a, and the lower end portion side of the main body 71 projects below the lower end portion of the hinge portion 1b of the hinge piece 1a, the pivot pin 8b. Is more easily guided to the insertion hole 1d of the hinge piece 1a. Moreover, by providing the taper portion 73 on the inner peripheral surface of the protruding peripheral wall portion of the main body 71, the assembly can be performed more easily.

After assembling the hinge pieces 1a and 8a as described above, the assisting tool 70 has the lower end portion by the sleeve plate 8c of the hinge piece 8a as shown in FIG. 11 (b). Since it is pushed up and protrudes upward by that amount, the assisting tool 70 is removed by this protruding portion.

After setting the work 1 as described above, the crane / balance SW is tilted to the crane side, the chuck / uncuck SW is turned off, and then the cylinder lowering lever (lowering switching valve 43) is turned on. The plunger of the balance cylinder 20 extends downward and the face material holding means 10 descends. When the face material holding means 10 descends,
The above-mentioned ascending limit switch 24 is turned off and is released O
Since the K lamp is turned on and the driving of the pressing cylinder 14 is stopped, the work 1 can be detached, and the work is completed.

After that, when another work 1 is transported and attached, the above procedure may be repeated.

In the above embodiment, the vertical moving means, that is, the balance cylinder 20 is mounted in the vertical state. However, as shown in FIG. 12, the balance cylinder 20 may be arranged in the horizontal state. In this case, the above limit switch is connected via the balance hoist unit 70 attached to the balance cylinder 20.

In this case, a wire 72 connected to the frame 11 is wound around the pulley 72 mounted on the plunger 21 in a rectangular frame-shaped unit body 71 connected to the cylinder body of the balance cylinder 20 so that the wire 73 can be wound and unwound. The balance hoist unit 70 is formed. The main body 71 of the balance hoist unit 70 is movably attached to the girder rail 32 of the horizontal moving means 50 via the trolley 38.

By arranging the balance cylinder 20 in the horizontal state in this way, it is possible to cope with the case where the effective height is small, and the space can be effectively used. Since the other parts of the second embodiment are the same as those of the first embodiment, the same parts are designated by the same reference numerals and the description thereof will be omitted.

In the above embodiment, the case where the balance cylinder 20 is a pneumatic cylinder has been described, but it is also possible to use a hydraulic cylinder. Further, in the above embodiment, the case where the surface material is an entrance door attached to the entrance of the building unit has been described, but the surface material does not necessarily have to be the entrance door, and other surface materials such as hard panels may be used. It may be. Further, it is needless to say that the present invention can be applied to a device that simply conveys the face material to a predetermined place.
