Abstract
A compact and high capacity sorting system includes a transportation vehicle travelling along a travelling route where the transportation vehicle may diverge and merge, and raising and lowering a transfer device; racks provided along the travelling route and having a height corresponding to multiple floors; an arrival area, a shipment area, and a sorting area, each provided along an outer periphery of the travelling route; and a controller controlling the transportation vehicle to transport commodities from the arrival area to the sorting area via the racks, and transport commodities from the sorting area to the shipment area.
Claims3
A sorting system for sorting and shipping commodities, the sorting system comprising:
- a pallet transportation vehicle that travels along a travelling route and is able to diverge and merge along the travelling route;
- a case transportation vehicle that is structurally different from the pallet transportation vehicle, travels along the travelling route, and is able to diverge and merge along the travelling route;
- racks provided along the travelling route and having a height corresponding to multiple floors;
- an arrival area, a shipment area, and a sorting area provided along an outer periphery of the travelling route;
- and
- a controller configured or programmed to control each of the pallet transportation vehicle and the case transportation vehicle to transport the commodities from the arrival area to the sorting area via the racks and transport the commodities from the sorting area to the shipment area;
- wherein
- the travelling route includes rails along which both the pallet transportation vehicle and the case transportation vehicle travel;
- the rails are provided in a ceiling space of a building accommodating the sorting system;
- and
- each of the pallet transportation vehicle and the case transportation vehicle includes a carriage that travels along the rails, a mast suspended from the carriage, and an elevation platform that includes a transfer device and is able to be raised and lowered along the mast.
A sorting method for sorting and shipping commodities using a sorting system including a pallet transportation vehicle that travels along a travelling route and is able to diverge and merge along the travelling route, a case transportation vehicle that is structurally different from the pallet transportation vehicle, travels along the travelling route, and is able to diverge and merge along the travelling route, racks provided along the travelling route and having a height corresponding to multiple floors, an arrival area, a shipment area, and a sorting area along an outer periphery of the travelling route, and a controller, the method comprising:
- transporting the commodities from the arrival area to the sorting area via the racks and transporting the commodities after sorting from the sorting area to the shipment area by each of the pallet transportation vehicle and the case transportation vehicle under control of the controller;
- wherein
- the travelling route includes rails along which both the pallet transportation vehicle and the case transportation vehicle travel;
- the rails are provided in a ceiling space of a building accommodating the sorting system;
- and
- each of the pallet transportation vehicle and the case transportation vehicle includes a carriage that travels along the rails, a mast suspended from the carriage, and an elevation platform that includes a transfer device and is able to be raised and lowered along the mast.
