After the first glass plate mounting transfer body 57 is moved to one side end of the loading platform 2 by the first lifting hydraulic cylinder 61, when the t-th moving hydraulic cylinder 59 is actuated, the first moving hydraulic pressure is increased. The stopper member 6 is located above the piston rod 7 of the cylinder 59.
8, the first movable support 55 moves from one side end of the loading platform 2 toward the center along the fixed guide rail 63 via the first moving member 64, and the first movable support body 55 and the first. A glass plate mounting/transfer body 57 is located near one end of the loading platform 2.

Furthermore, when the second lifting hydraulic cylinder 62 between one column 76 and the other column 77 of the second movable support 56 is actuated, the piston rod of the second lifting hydraulic cylinder 62 moves slightly upward. The second glass plate mounting transfer body 58 moves up slightly along one support column 76 of the second movable support 56 via the movable guide rail 79, and the second glass plate mounting transfer body The supporting leg member (not shown) of the mounting/transferring body 58 comes off from the upper surface of the fixed guide rail 63, and the second glass plate mounting/transferring body 58 descends due to a drop in the hydraulic pressure of the second lifting hydraulic cylinder 62 or oil leakage. This is prevented by the supporting leg member.

After the supporting leg member of the second glass plate mounting/transfer body 58 is detached from the upper surface of the fixed guide rail 63 by the second lifting hydraulic cylinder 62, when the second moving hydraulic cylinder 60 is actuated, the second movement is started. The piston rod 72 of the hydraulic pressure 1 cylinder 60 protrudes toward the other end of the loading platform 2, and the second movable support 56 moves from the center of the loading platform 2 along the fixed guide rail 63 via the second moving member 65. The second glass plate mounting transfer body 58 moves toward the other end of the loading platform 2 together with the second movable support 56 , and A support column 76 and a second glass plate mounting/transfer body 58 are located at the other end of the loading platform 2 .

After one support column 76 of the second movable support 56 is moved to the other end of the loading platform 2 by the second moving hydraulic cylinder 60, when the second lifting hydraulic cylinder 62 is actuated, the second lifting/lowering The piston rod of the hydraulic cylinder 62 protrudes downward, and the second glass plate mounting transfer body 58 is moved from the other end of the loading platform 2 to one support column 7 via a movable guide rail 79.
6, the supporting leg members of the second glass plate mounting and transporting body 58 touch the ground, and the second glass plate mounting and transporting body 58
The glass plate 47 is supported in a standing state against the ground, and then the work of loading the glass plate 47 onto the second glass plate mounting/transfer body 2 58 is performed.

In addition, while the second glass plate mounting/transfer body 58 is lowered toward the ground from the other end of the loading platform 2, the glass plates 47 loaded onto the second glass plate mounting/transfer body 58 are unloaded. I do.

After the loading work of the glass plate 47 onto the second glass plate mounting/transfer body 58 is completed, the second lifting hydraulic cylinder 62 is operated, and the piston rod of the second lifting hydraulic cylinder 62 is moved upward. When the second glass plate mounting and transporting body 58 moves back, the second glass plate mounting and transporting body 58 rises along the one support column 76 of the second movable support 56 via the movable guide rail 79, and the second glass plate mounting and transporting body 58 from the ground to the other end of the loading platform 2.

After the second glass plate mounting transfer body 58 is moved to the other end of the loading platform 2 by the second lifting hydraulic cylinder 62, when the second moving hydraulic cylinder 60 is actuated, the second moving hydraulic cylinder 60 is activated. The piston rod 72 of the cylinder 60 is connected to the stopper member 6
7, the second movable support 56 moves from the other end of the loading platform 2 toward the center along the fixed guide rail 63 via the second moving member 65, and the second movable support The body 56 and the second glass plate mounting/transfer body 58 are located near the other end of the loading platform 2.

First movable support body 55 and first glass plate mounting transfer body 5
7 is moved toward one side end of the loading platform 2 by the first moving hydraulic cylinder 59, and the second movable support body 56 and the second glass plate mounting/transfer body 58 are moved by the second moving hydraulic cylinder 59. 60 toward the other end of the loading platform 2, the loading platform 2 is released from support by the outrigger 11, and then,
By rotating and closing the side flap plates 10.10 on both sides of the loading platform 2, the locking device locks the first movable support 55 and the second movable support 56 against the fixed guide rail 63. and lock the first glass plate mounting transfer body 57.
The glass plate 47 loaded on the second glass plate loading/transfer body 58 is then transported by the truck 1.

First movable support 55. First glass plate mounting transfer body 57
and the position of the center of gravity relative to the total weight of the glass plate 47 and the second movable support 56. Adjustments are made so that the positions of the centers of gravity relative to the total weights of the second glass plate loading/transfer body 58 and the glass plate 47 are balanced with respect to the loading platform 2.

Effects of the Invention As described above, according to the glass plate loading and unloading device of the present invention, the movable support body is moved in the vehicle width direction of the loading platform by the horizontal movement device, so that the glass plate loading and unloading body is moved from the movable support body. The glass plate mounting transfer body moves from the side edge of the loading platform toward the ground along the movable support by the lifting device, so that the glass plate can be moved to the side edge of the loading platform. The glass plate can be loaded and unloaded at a low position, eliminating the need for the operator to climb up and down the loading platform while holding the glass plate, and making it possible to load and unload the glass plate onto and from the glass plate carrying body without the hassle. This is easy to do, and the lifting device moves the glass plate carrying transport body loaded with glass plates from the ground to the side edge of the loading platform along the movable support, so that the glass plate can be moved along with the glass plate carrying body to the loading platform. Since the horizontal moving device moves the movable support from the side edge of the loading platform toward the center, it is possible to return the glass plate-mounted transfer body together with the movable support to any position on the loading platform. When the glass plate is placed on the top of the loading platform, the vertical line passing through the center of gravity of the movable support, the glass plate loading/transferring body, and the loading platform containing the glass plate must be adjusted so that it coincides with the center line of the heavy wheels. I can do it.
