Next, the effects of the loading device 20 according to this embodiment will be described.
As described above, in the loading device 20, when the loading device 20 pushes the loading platform P with the cargo B placed thereon on the plate member 24 on the base part 22, the loading platform P is moved together with the cargo B. It moves in the cargo conveying direction and is loaded into the container C (loaded). Specifically, when loading, the moving portion 44 to which the moving force is applied from the drive source 46 moves on the base portion 22 in the cargo conveying direction M. As shown in FIG. More specifically, the driving force from the electric motor, which is the driving source 46, is transmitted to the driving wheels 52 of the traveling unit 50, and the traveling unit 50 travels on the vertical member 32 along the load conveying direction M. During this travel, the loading platform P on which the cargo B is placed is pushed in the cargo transporting direction M by the pushing members 48 bridged over the pair of traveling units 50 via the spacer member 64, and the loading platform P moves in the cargo transporting direction M. loaded into container C together with cargo B.

Therefore, the loading platform P on which the load B is placed can be moved in the load conveying direction M with a relatively small force. Thereby, size reduction of the moving apparatus 26 can be achieved. In particular, since the plurality of protrusions 42 extend along the longitudinal direction of the plate member 24 and are formed at intervals in the width direction, the protrusions 42 are less likely to tilt due to the weight of the load B, and the load B is placed thereon. The loaded loading platform P can be smoothly moved in the cargo conveying direction M.

Further, in the loading device 20, since the plate member 58 is provided on the lower surface of the loading platform P, the frictional force generated between the plate member 24 on the base portion 22 can be further reduced.

In the loading device 20, the plurality of panel members 30 fitted inside the frame 28 of the base portion 22 are removed, the assembly of the frame 28 is released, and the pair of vertical members 32 and the pair of horizontal members 34 are assembled. The base can be easily dismantled by separating it into two parts. On the other hand, in the loading device 20, a pair of vertical members 32 and a pair of horizontal members 34 are assembled to form a frame 28, and a plurality of panel members 30 are fitted inside the frame 28 to form the base portion 22.

In the loading device 20 of the first embodiment, the traveling unit 50 travels on the base portion 22 by the driving force from the driving source 46, but the present invention is not limited to this configuration. For example, the drive source 46 is attached to the base portion 22, and a pair of pulleys (or gears) are attached upstream and downstream of the base portion 22 in the cargo conveying direction M, and a belt (or The travel unit 50 may be configured to travel in the load conveying direction M in accordance with the circulating motion of the chain. Further, for example, all the wheels of the traveling unit are roller wheels, a rack is fixed to the base portion 22 along the load conveying direction M, a pinion gear is attached to the drive source 46 attached to the traveling unit, and the rotational force of the pinion gear is may be converted into a linear force of the traveling unit by the rack to cause the traveling unit to travel. Furthermore, for example, all the wheels of the traveling unit are roller wheels, and a ball screw is fixed to the base portion 22 along the load conveying direction M, and the driving force from the driving source 46 attached to the base portion 22 is transferred to a gear box or the like. The traveling unit 50 may be configured to travel by connecting the travel unit to a slider that converts the torque into the rotational force of the ball screw and moves on the screw shaft as the ball screw rotates. For the moving mechanism using a pair of pulleys (or gears) and a belt (or chain), the moving mechanism using a rack and pinion gear, and the moving mechanism using a ball screw and slider, the frame 28 may be installed inside the frame 28, or may be installed outside the frame 28.
