When the containers 13 scattered in the field are picked up and loaded with the loading cart having the above configuration, the procedure is as follows.

That is, when the cart 1 is advanced so that the container 13 is positioned between the left and right pair of guide means 20, the front ends of the left and right pair of guide means 20 enter the underside of the flange portion 21 of the container 13, and the Horizontal rollers 25 on the upper plate portion 23 side of the guide frame 22 lift the container 13 via the flange portion 21. When the cart 1 moves further forward, the container 13 moves relatively backward (arrow a) and its end gets caught on the conveyor 12, so the conveyor 12 forces the container 13 backward. transport. At this time, the flange portion 21 of the container 13 rises from the horizontal rollers 25 on the rear side of the guide means 20, so that the container 13 can be loaded onto the loading platform 3 by the conveying force of the conveyor 12. Further, although the orientation of the container 13 in the field is not constant, since the guide means 20 is spread out in the front, it is possible to reliably pick up and load the container. Furthermore, as shown by the imaginary lines in FIG. In response, one of the guide means 20 swings outward as shown in the imaginary line, so the container 13 is not damaged.
Furthermore, regarding the displacement of the container 13 in the left and right direction,
The vertical rollers 28 of the guiding means 20 act to reliably guide the container 13 onto the transport conveyor 12. Therefore, regardless of the orientation of the containers 13, the containers 13 scattered in the field can be lifted up and automatically loaded onto the loading platform 3. Loading platform 3
The upper containers 13 may be rearranged as appropriate by the operator.
