A case where the panel B sorted by the sorting device A is transferred onto the carriage C while maintaining the horizontal state will be described with reference to FIG. First, the sorting device A with the panel B clamped faces the carriage C, and the elevator 6 is lowered without operating the winch 24, that is, with the ratchet mechanism 24b in a free state. At this time, the arm 14 clamping the panel B descends with the upper surface of the rear end contacting the lower surface of the arm stopper 8. That is, the arm 14 and the panel B descend while maintaining the horizontal state, and the panel B is placed on the upper surface of the carriage C and stops descending as shown in FIG. Thereafter, by operating the hydraulic pump 23 to retract the rod 19a of the hydraulic cylinder 19 and release the clamp on the panel, the panel B can be transferred onto the carriage C as shown in FIG. It is.

A case where the panel B sorted by the sorting apparatus A is transferred to the carriage D in a small edge state will be described with reference to FIG. First, the sorting device A with the panel B clamped faces the carriage D, the wire 26 is wound by the handle 24c of the winch 24, and the arm 14 is lifted to exert a force. At this time, when the arm 14 is located at a position higher than the sum of the height of the mounting surface of the carriage D and the width of the panel B from the floor, it is sufficient to wind the wire 26 to such an extent that the wire 26 is tensioned. When the arm 14 is at a position lower than the above-mentioned size, the arm 14 is raised or the wire 26 is wound by the winch 24, and the arm 14 is rotated counterclockwise about the rotation pin 9. It is necessary. Next, as shown in FIGS. 7B and 7C, when the lifting pedestal 6 is lowered from the above state, the arm
Since the distance between the pin 16a of the mounting bracket 16 and the winding drum 24a is maintained constant by the wire 26, the arm 14 rotates counterclockwise about the rotation pin 9 as the lifting pedestal 6 descends. I do. Further, with the rotation of the arm 14, the mounting bracket 16 moves rearward around the winding drum 24a. Therefore, the panel B clamped by the clamp mechanism 18 can be set up with the rear side downward and the front side upward. And the side of panel B is a trolley D

The panel B can be transferred onto the carriage D.

In the above-described embodiment, the hydraulic jack 10,
Although the hydraulic pump 23 and the winch 24 have been described as being operated manually, it is obvious that an electric pump or a winch may be used. Further, in the above-described embodiment, the case where the vertical frame 1b is configured by a pipe has been described. However, the present invention is not limited to this configuration. For example, the vertical frame 1b may be configured by using a section steel such as a C section steel. In this case, it is possible to guide the elevating pedestal 6 up and down along the mast by forming a mast that becomes a vertical frame by the shaped steel and by bringing the roller 6c provided on the elevating pedestal 6 into contact with the inner surface of the groove. It is.
