At the same peripheral speed as the movement, the transfer roller 5 is rotated so that the upper surface thereof moves in the direction (C direction) opposite to the movement direction (B direction) of the roller conveyor 4. In this way, the transfer roller 5 is moved while the roller conveyor 4 is moved backward.
10 are tuned and rotated in the opposite direction at the same speed, and FIG.
As shown in (b), the roller conveyor 4 moves in a direction away from the loading table 2 while the plate material 1 on the loading roller 5 moves onto the loading table 2. By further rotating the transfer roller 5 in the reverse direction at the same speed while rotating the roller conveyor 4 backward,
The plate 1 on the transfer roller 5 can be completely transferred onto the loading table 2 as shown in FIG.

Since the plate 1 is temporarily positioned in the width direction on the transfer roller 5 of the roller conveyor 4 as described above, the plate 1 is transferred to the loading table 2 at a substantially accurate position. Then, the plate 1 loaded on the loading table 2 is positioned more accurately, and the plate 1 is aligned vertically. That is, first, the table tilt cylinder 8

Next, air is blown from the air blow nose 11 of each positioning plate 9 toward the end surface of the plate material 1 loaded on the loading table 2. When air is blown onto the end surface of the plate 1 of the loading table 2 as described above, air enters between the loading table 2 and the plate 1 and between the upper and lower portions of the plurality of plate 1, and the plate 1 is in a floating state. Then, in this state, the vibration motor 86 of the vibration generator 10 is operated to operate the vibration generating weight 8.
By rotating 8, the loading table 2 is vibrated. When the loading table 2 is vibrated in this manner, the plate 1 on the loading table 2 moves downward along the inclination of the loading table 2, and the adjacent side edges of the plate 1 contact the respective positioning plates 9. The plurality of plate members 1 on the loading table 2 can be aligned with each other with reference to each positioning plate 9. Here, since the plate material 1 is lifted by the air blown from the air blow nose 11,
The plate 1 can be easily moved and positioned on the loading table 2 without damaging the plate 1 by rubbing the plate 1 with each other or rubbing the plate 1 with the loading table 2. .

When the positioning of the plate 1 is completed in this way,
The generation of vibration by the vibration generator 10 and the blowing of air from the air blow nose 11 are stopped, and the loading table 2 is returned to a horizontal state. The above operation is performed so that the total thickness of the plate 1 on the loading table 2 is about 20 mm. By repeating the process until the thickness is increased, a plurality of plate materials 1 can be stacked on the loading table 2 while being aligned vertically.

The plate 1 is placed on the loading table 2 to the specified thickness.
Is loaded, air is blown upward from the air blowing holes 89 on the upper surface of the loading table 2 to load the loading table 2.
The plate 1 is lifted on the table, and the positioning plate 9 is retracted from the upper surface of the loading table 2 by operating the lifting / lowering cylinder 81 to move the positioning plate 9 downward.
