The fork 2 is rotated to invert the forklift box holding device 10 so that the base 11 is on the upper side. At this time, the forklift box holding device 10 is held on the fork 2 by the fork holding gap 23. Further, the forklift box 1 is held by the holding device 10 of the forklift box by the side holding members 12 and the stoppers 15. Thereby, a conveyed product can be dropped from the inside of the box 1 for forklifts to a loading platform, another container, etc., and can be reloaded.
[0036]
When the transshipment of the conveyed product is completed, the fork 2 is rotated, and the forklift box holding device 10 is reversed and returned to the original state so that the base 11 is on the lower side. The fork 2 is lowered and the forklift box holder 10 is placed. The distance between the forks 2 is narrowed, the forks 2 are removed from the fork holding gaps 23, and moved between the support portions 21. At this time, the operation unit 14 is released from the fork 2 and protrudes by an urging force. Thereby, the motion transmission member 16 connected to the operation part 14 moves each stopper 15 to an open position, and opens the upper edge of the forklift box 1.
[0037]
The fork 2 is raised between the support portions 21 from a position lower than the support surface 21d. The fork 2 is inserted into the support groove 5 from the bottom side of the forklift box 1 and the forklift box 1 is lifted. At this time, the stepping member 13 is opened, and each side holding member 12 rotates to the open position in conjunction with the ascent of the forklift box 1 by the urging force. Thereby, the forklift box 1 can be easily moved from between the side holding members 12 of the forklift box holding device 10. The above-described steps can be repeated with another forklift box 1 mounted on the fork 2.
[0038]
Thus, since the forklift box holding device 10 can be held and reversed by the fork 2, it does not require the labor of the operator, and it is easy to reload the conveyed items. In addition, since the existing forklift box 1 can be mounted and used, the introduction cost can be reduced.
