Next, the operation of the panel body transporting device will be described.

The transfer device comprises a movable frame 2 and a conveyor 3.
Since each of the driving mechanisms is connected to the output portion of the reduction mechanism 7, the operation of one motor 6 causes the movable frame 2 to reciprocate on the base 1 and at the same time, the conveyor 3 rotates in the normal and reverse directions. That is, when the movable frame 2 is moved from the retracted position B shown by the phantom line in FIG. 1 to the forward position F also shown by the phantom line, the conveyor 3 rotates forward and the jig 12 moves from the end of the horizontal portion 3a. The movable frame 2 is moved to the inclined portion 3b.
If is moved in the opposite direction, the conveyor 3 is also reversed.

For example, when the additional production line is installed in parallel with the main production line of the panel body, the above-mentioned transfer device is arranged such that the horizontal portion 3a reaching the retracted position B is located on the carry-out side of the additional production line. The inclined portion 3b reaching the forward movement position F is arranged so as to extend on the erection device (shown by imaginary line) S of the main production line.

Then, after the transport device receives the panel body P by the jig 12 on the horizontal portion 3a at the retracted position B,
At the same time as the movable frame 2 is moved, the conveyor 3 is rotated to move the panel body P together with the jig 12, and at the forward movement position F, the jig 12 is moved to the inclined portion 3b to bring the panel body P to the standing state. .

Here, in the conveyor 3 in which the horizontal portion 3a and the inclined portion 3b are continuous, if the front and rear end portions of the jig 12 in the moving direction are connected to the chain 10, the horizontal portion 3a shifts to the inclined portion 3b. At this time, the straight line distance between the two connecting portions becomes small, so that they cannot move. Therefore, in the carrying device, when the jig 12 is moved from the horizontal portion 3a to the inclined portion 3b, the jig 12 is rotated with respect to the connecting tools 13 and 14 as indicated by a virtual line in FIG. The second connector 14 is slid along the guide 15 so that the linear distance between the first and second connectors 13 and 14 is kept constant. Therefore, even when the angle of the inclined portion 3b with respect to the horizontal portion 3a is large, the panel body P together with the jig 12 is formed.
Will move smoothly.

Further, since the holding member 19 is provided with the cushioning member 21, the moving panel body P is not damaged. Since the holding member 19 is biased in the direction in which it comes into contact with the panel body P, it reliably holds the panel body P during conveyance.

As described above, in the panel body transporting apparatus according to the above-described embodiment, the panel body P loaded in the sideways state can be quickly brought to the upright state, which is the unloading posture, only by the continuous movement of the conveyor 3. Since the lifter in the main production line can be used for unloading, it is not necessary to add a new lifter or modify the ceiling conveyor.

Further, the carrying device can perform an operation according to the operating condition of the adjacent carrying device,
For example, the conveyor 3 may be detached (retracted) during the operation of the erection device S for the main production line, and further, the conveyor 3 may be in a neutral position where it does not interfere with either the main production line or the additional production line (see FIG. It is also possible to move the panel body P to the standby position by moving it to the position (indicated by the solid line 1), thereby increasing the operation rate of the entire production line.

In the above embodiment, the case where the panel body P carried out from the additional production line is carried to the carrying-out position of the main production line has been exemplified, but the carrying-out of a plurality of additional production lines is carried out to the horizontal portion 3a of the conveyor 3.
