There is no problem as long as it is possible. Even if the floor has a slanted portion, it may be anything that can move the multistage shelf device 15 manually.

Next, the procedure for transporting the plate body P by the plate body transport system 11 of the multistage press apparatus will be described. First, a plate-like body P (including a press plate) before forming is placed on a press plate 23 arranged in multiple stages from the opening 27 of the press device 12 by a loader device. The loader device may be a device that only loads a plate-like body (substrate) before molding onto the press device 12, and in that case, an unloader device that is the transfer device 13 is provided separately. Further, it may be a loader / unloader device that is used for both loading and unloading. In this case, it corresponds to the transfer device 13 of the present invention. Then, after the opening 27 of the press device 12 is closed and the inside of the vacuum chamber 24 is evacuated, the mold clamping cylinder 19 is operated, and the press plate 23 is sequentially pushed up from below to move the plate-like body P between the presses 23. Press to perform pressure forming. When the pressure molding is completed after a predetermined time has elapsed, the inside of the vacuum chamber 24 is returned to normal pressure, the opening 27 is opened, and the plate-like body P is lifted by a device (not shown) in the press device 12. Then, the arm 34 of the transfer device 13 (unloader device) that has been moved to the opposite position in front of the opening 27 is entered into the press device 12, and the plate-like body P is placed on the arm 34. Next, the arm 34 is retracted to a position where it does not interfere with the press device 12 and then rotated 180 °.

When placing the multistage shelf device 14, the arm 62 of the shelf lifting device 16 is inserted into the U-shaped arm contact portion 51 of the multistage shelf device 14 on the floor 18 to raise the arm 62. After the contact, the arm 62 is further raised to raise the entire multistage shelf device 14 from the floor 18. And it raises until the lower surface of the lower frame board 45 of the multistage shelf apparatus 14 becomes higher than the height of the mounting surface 39a of the shelf holding apparatus 15. Then, the shelf elevating device 16 on which the multistage shelf device 14 is placed is moved forward by human power and inserted to a position where the front surface of the multistage shelf device 14 contacts the stopper 43 of the shelf holding device 15. When the front surface of the multistage shelf device 14 comes into contact with the stopper 43, the arm 62 is lowered, and the lower surface of the lower frame plate 45 of the multistage shelf device 14 is placed on the placement surface 39 a of the placement portion 26. At the time of this insertion, both sides of the multi-stage shelf device 14 are guided by the guide members 41, so that no lateral displacement occurs with respect to the carry-in direction. Whether or not the multistage shelf device 14 is placed at an accurate position with respect to the shelf holding device 15 is detected by the two limit switches 40 of the shelf holding device 15 and is not placed at the exact position. The interlock is supposed to work. In this way, the multistage shelf device 14 is held at a position higher than the floor 18 by a predetermined height H.

  Then, in a state where it is confirmed that the multistage shelf device 14 is held at an accurate position on the shelf holding device 15, the arm support frame body 32, the arm fixing body 33, and the multistage state of the transfer device 13 remain. Each arm 34 on which the plate-like body P is placed is moved horizontally to advance, and the arm 34 enters between the respective shelf members 47 of the multistage shelf device 14 through the carry-in port 38 on the shelf holding device 15. Let When the arm 34 is advanced to a predetermined position, the arm 34 is then lowered, and the plate-like body P is placed on each shelf member 47 in a multistage state.
