[0002]

2. Description of the Related Art Conventionally, as a branch transporting device for a load, as shown in FIGS. 15 to 17, a pair of forward and backward transporting devices 1 extending in the forward and backward direction are arranged at an interval in the left and right direction. An elevating frame 3 which is moved up and down by an elevating drive device 2 is provided at an intermediate portion in the anteroposterior direction between the anterior-posterior transfer devices 1, and a traverse switching transfer device driven by a traverse transfer drive device 4 on the elevating frame 3. The intermediate portion of a stopper 10 having an upper end protruding above the front-rear transfer device 1 in front of the elevating frame 3 is provided on the frame 6 of the front-rear transfer device 1 by a horizontal shaft 11. The lower end of the transfer device 10 and the frame 6 of the forward and backward transfer device 1 are connected by a stopper rotating fluid pressure cylinder 12. The transporting device 9 is provided at a position where the transporting device 9 is moved, and when the luggage 13 is transported forward through the portion of the traversing switching transporting device 5 by the longitudinal transporting device 1, the stopper 10 is moved forward and backward by the stopper rotating fluid pressure cylinder 12. The package 13 is rotated so as not to protrude upward from the transfer device 1 (see a chain line state in FIG. 17), and the luggage 13 transported forward by the front-rear transfer device 1 is stopped at the traverse switching transfer device 5, and the traverse is performed. When the transfer is performed in the left-right direction by the switching transfer device 5 and the traverse transfer device 9, the stopper 10 is rotated by the stopper rotation fluid pressure cylinder 12, and the upper end of the stopper 10 is moved to the front-rear transfer device 1.
There is known a branch transport device configured to protrude upward.
