The front end of the upper surface portion of the container 7 moves back and forth to make the conveyance distance variable.

In the horizontal transfer device 11, a guide rail 29 is provided on a support 28 that is erected on the main body frame 16 of the vertical transfer device 10, and is provided with a long guide rail 29 protruding from the side edge in the width direction of the vertical transfer device 10. A traveling conveyance body 30 is suspended, and an adsorption body 32 made of an electromagnet, a bar magnet, etc., supported by an actuator 31 so as to be vertically movable, is provided on the traveling conveyance body 30. The entire horizontal transfer device 11 is provided movably in the vertical transfer device 1.
It rotates together with 0.

The rotation and expansion/contraction of the vertical transfer device 10 of the transfer means 7 and the movement of the horizontal transfer device 11 are controlled by a control device (not shown) in conjunction with the steel plate cutting machine 6.

Next, in the stock means 4, a plate loading platform 33 is supported in a vertically movable manner by a lifting device 36 including a cross link 34 and a lifting cylinder 35, and this lifting movement is also controlled by a control device ζ in conjunction with the trowel and other equipment. Ru.

To explain the operation, the steel plate 1 is sequentially cut by the steel plate cutting machine 6 according to the planar shape, and the cut-off plates are sorted by the conveyor 9 into the plate pieces 2 that will become products, waste materials 3, and re-cut pieces. If there is no change in direction, the plate pieces 2 that are sorted into secondary materials to be processed are directly fed to the vertical transfer device 10 of the transfer means 7, and when the direction is to be changed, the transfer means 7 is rotated to move them horizontally. It is supplied via a transfer device 11 to a vertical transfer device 10 .

That is, when turning, as shown in FIG. It is held by the suction body 32 and conveyed onto the vertical transfer device 10, and at the same time, the horizontal position is adjusted by releasing the holding and supplying the material. The left and right positions are matched by the transfer device 11.
