The second detection portion is configured to detect stacking information. The controller is configured to control operation of the gripping portion based on the article information and the stacking information.
1. A cargo handling apparatus, comprising:
a first conveyor portion configured to convey an article to be handled in a first direction;
a first detection portion configured to detect article information relating to the article conveyed through the first conveyor portion;
a second conveyor portion configured to receive the article conveyed through the first conveyor portion and convey the article in a second direction intersecting the first direction;
a gripping portion configured to grip the article on the second conveyor portion to move the article in a third direction intersecting the second direction and arrange the article in an accumulating portion;
a second detection portion configured to detect stacking information indicating an arrangement state of articles in the accumulating portion; and
a controller configured to control operation of the gripping portion based on the article information and the stacking information, wherein
the gripping portion includes:
a comb-tooth shaped member configured to scoop up the article on the second conveyor portion; and
a suction portion configured to suck the article,
the second conveyor portion includes a roller conveyor constituted by a plurality of rollers, and
the comb-tooth shaped member is arranged in such a manner as to be vertically movable between the plurality of rollers.
2. The cargo handling apparatus according to claim 1 , wherein
the first conveyor portion includes a first transfer conveyor configured to transfer the article to the second conveyor portion, and
the first transfer conveyor includes a transfer conveyor—vertically moving mechanism configured to vertically move the first transfer conveyor in order to adjust a level of the first transfer conveyor to a level of the second conveyor portion.
3. The cargo handling apparatus according to claim 1 , wherein the first conveyor portion includes a direction-changing conveyor configured to reverse a conveyance direction of the article from the first direction in such a manner that the article is receivable by the second conveyor portion.
4. The cargo handling apparatus according to claim 1 , further comprising a buffer portion configured to receive the article conveyed through the first conveyor portion and to cause the article to temporarily stand by before the article is conveyed to the second conveyor portion.
5. The cargo handling apparatus according to claim 1 , wherein the first conveyor portion includes an attitude changing portion configured to change an attitude of the article.
6. The cargo handling apparatus according to claim 1 , wherein
the second conveyor portion includes a second conveyor configured to receive the article from the first conveyor portion, and
the second conveyor includes a transfer conveyor—vertically moving mechanism configured to vertically move the second conveyor in order to adjust a level of the second conveyor to a level that is taken at a time when the article is arranged in the accumulating portion.
7. The cargo handling apparatus according to claim 1 , further comprising a positioning mechanism configured to adjust a position of the article in the second direction within the second conveyor portion.
8. The cargo handling apparatus according to claim 1 , further comprising a movable flap mechanism configured to support the article on the second conveyor portion in a case where the article is gripped with the gripping portion within the second conveyor portion.
9. The camo handling apparatus according to claim 1 , wherein the accumulating portion is movable and includes a locking mechanism configured to lock the accumulating portion in a case where the accumulating portion is arranged.
10. The cargo handling apparatus according to claim 9 , comprising:
a safety fence configured to surround the arranged accumulating portion; and
a safety door configured to open and close a part of the safety fence.
11. The cargo handling apparatus according to claim 8 , wherein
the movable flap mechanism stands upright by means of a spring, and
the movable flap mechanism falls down with respect to the second conveyor when the movable flap mechanism is pressed by the article.
12. The cargo handling apparatus according to claim 1 , wherein
the comb-tooth shaped member comprises a first comb-tooth shaped member and a second comb-tooth shaped member,
the plurality of rollers comprise a first roller, a second roller, and a third roller,
the first comb-tooth shaped member is arranged in such a manner as to be vertically movable between the first roller and the second roller, and
the second comb-tooth shaped member is arranged in such a manner as to be vertically movable between the second roller and the third roller.
