(Prior art) As prior art related to the present invention, for example,
-41684, etc. In the above-mentioned prior art, after a plate material loaded on a cart is suctioned and lifted by a vertically movable suction device, a plurality of receiving bars provided on an endless chino are placed between the suction device and the cart. to be located. After that, the plate material dropped from the suction device is received by the receiving frame, and then the chino is moved in an appropriate direction to carry the plate material into a plate processing machine or the like.

(Problems to be Solved by the Invention) ``In the prior art as described above, the plate material is sucked and lifted by a suction device, and then the plate material is dropped onto a support bar provided on the chino for conveyance. When the chino is run at a sudden acceleration, slipping occurs between the plate material and the receiving crosspiece, making it impossible to increase the conveyance speed at a sudden acceleration, which poses a problem in improving work efficiency.

In addition, when separating loaded boards one by one, the suction device picks up the entire top board and lifts it, so the area near the end of the second board is the first board. There was a problem in that there was a problem such as the position being in close contact with the container, which could result in displacement from the loaded position.

The present invention has been made in view of the above-mentioned problems.

epigastric action is stopped.

When the loaded plate material W is located at a predetermined height position as described above, the plate material end face detector 65 in the plate material suction and lifting device 9 is held in an operative state, and the vertical movement cylinder 5
7.57", each suction tool 51..59 is held in a raised state, and the plate material suction lifting device 9 is moved from the left side to the right side in FIG. 1. Then, the plate material end face detector 65 detects the end face, the movement of the plate material suction and lifting device 9 is stopped, and the suction tools 51 and 59 are lowered to suck the vicinity of one end of the uppermost plate material W.

After the vicinity of one end of the plate W is suctioned by each suction tool 51.59 as described above, each suction tool 51.59 is slightly raised or the lid device 7 is slightly lowered to remove the uppermost sheet material W. Separate one end of the plate and one end of the second plate. Then, as shown in FIG.
The plate material W is separated by inserting it between the uppermost plate material and the second plate material, and the uppermost plate material is supported.

When the plate material W is supported by the plate material support member 77, and the suction tools 51 and 59 are sucked and lowered near one end of the plate material W, and are pressed against the plate material support member 77, By moving the chino 75 clockwise in FIG. 1 and synchronously moving the plate suction and lifting device 9 to the right, the plate W can be transported to the plate processing machine. In other words, since the plate material W and the plate material support member 77 can be transported without slipping, the plate material can be transported with rapid acceleration.
