Next, the operation of the box-shaped package transport device according to the embodiment of the present invention will be described. First, as shown in FIG.
The box-shaped packages 1A and 1B placed in different directions on the pallet 2 are placed on the lifting platform 4 as shown by a two-dot chain line in FIG. As shown in the figure, the lifting platform 4 is moved down into the recess 10,
In addition, the uppermost box-shaped luggage 1 (1A) to be erected is held at a level slightly higher than the levels at the upper ends of the movable roller conveyor 8 and the first member 46.

Next, the first box-shaped luggage 1A to be erected is moved forward by the luggage advance pusher 5, and
As shown in FIG. 2, the plurality of upright members 43 are arranged on the first member 46, and then the upright members 43 are rotated by 90 ° by the rotation driving device 9 as shown by two-dot chain lines in FIG. Then, the box-shaped luggage 1A is raised to the state of 1B, and after the box-shaped luggage 1B is moved forward, the respective chain conveyors 59 are raised to support the box-shaped luggage 1 by the chain conveyors 59. By driving the chain conveyor 59 to convey the box-shaped package 1 and passing the box-shaped package 1 through the second member 47 in a horizontal state, the upright member 43 is rotated by 90 ° in the reverse direction, Return to the state shown by the solid line in FIG. In the above operation, when the box-shaped package 1 on the pallet 2 is pushed by the package advance pusher 5 and moved on the package supporting roller 6, the movable roller conveyor 8 is moved forward to the pallet 2 side. Thus, the gap between the load supporting roller 6 and the pallet 2 is eliminated, and the movable roller conveyor 8 receives a downward force acting on the lower front end of the box-shaped load 1 pushed by the pusher 5 to form the box. Even if the luggage 1 is pushed by the luggage advancing pusher 5, the posture does not tilt forward, and therefore the luggage 1 can be reliably pushed and smoothly moved to the luggage support roller 6 side.

Next, as shown in FIG.
Is transported upright as described above.

Next, the third and subsequent box-shaped luggage 1B that does not need to be erected is conveyed by the movable roller conveyor 8 and a number of luggage support rollers 6 without performing the erection operation among the above-mentioned operations.

[0021]

According to the present invention, the pallet 2 on which the box-shaped package 1 is placed in a plurality of stages is placed on the lifting platform 4 which is moved up and down by the lifting drive device 3, and the box-shaped package 1 is A luggage advancing pusher 5 is provided at the rear, and a large number of luggage support rollers 6 extending in the left-right direction are provided at the front of the pallet 2.
Are provided at an interval in the front-rear direction, and between a rear portion of the load supporting roller 6 and a front portion of the pallet 2, a fixed roller parallel to the axis of the load supporting roller 6 and shorter than the roller 6. A conveyor 87 and a movable roller conveyor 8 are provided side by side, and the movable roller conveyor 8 faces the front surface of the non-transportable object below the box-shaped luggage 1 to be moved when the forward / backward movement driving device 7 moves forward. Because of the arrangement, the pallet 2 of the box-like luggage 1
, And only the upper box-shaped package 1 can be smoothly transported from an arbitrary stage. That is, the lowermost box-shaped package 1 can be transported sequentially from the uppermost box-shaped package 1 or all the box-shaped packages 1 on the pallet 2 There is an effect that the luggage 1 can be conveyed together.
