A picking system includes a multi-tier sorting device having ports in a plurality of tiers at different levels in a top-bottom direction, and sorts and discharges each of articles to one of the ports in the plurality of tiers; a plurality of first transport devices respectively corresponding to the ports in the plurality of tiers; and a second transport device configured to receive the articles from the first transport device and transport the articles. The second transport device has a second transport surface movable upward and downward, and, in a state where the second transport surface is located at a height corresponding to a terminal end portion of the first transport surface of one of the plurality of first transport devices, the second transport device receives the articles discharged from the terminal end portion of the first transport surface and transports the articles, with use of the second transport surface.

Picking system

A control system performs a shipping process, a replenishing process, a moving process, and a returning process. The replenishing process is for, in a case in which the number of first-type articles located in a first warehouse has become less than or equal to a quantitative threshold, transporting the first-type articles located in a second warehouse to the first warehouse, thereby stocking the articles into the first warehouse while the articles are in containers. The moving process is for transporting second-type articles that have become the picking target articles and are located in the second warehouse to the first warehouse, thereby stocking the articles into the first warehouse while the articles are in the containers. The returning process is for transporting the containers accommodating the second-type articles that have been returned to the first warehouse upon completion of the shipping process, from the first warehouse to the second warehouse.

Article storage facility

An article sorting facility includes: a first floor including a plurality of first travel paths; a second floor installed at a different height from the first floor in a vertical direction, and including a plurality of second travel paths; a plurality of first elevation mechanisms connecting terminating ends of the first travel paths to starting ends of the second travel paths; a plurality of second elevation mechanisms connecting terminating ends of the second travel paths to starting ends of the first travel paths; a plurality of receiving sections configured to receive articles from the transport vehicles; and at least one supply section configured to supply the articles to the transport vehicles. The plurality of second travel paths overlap corresponding first travel paths or corresponding receiving sections as viewed in the vertical direction, at least in a partial segment.

Article sorting facility

A shield gate includes a door member disposed in a gap region located between an intra-area transport unit and an extra-area transport unit in a transport direction in a closed state in which the shield gate shields an opening, and is disposed at a position displaced from the gap region in an open state in which the shield gate opens the opening. A second interval is a length of the gap region that allows the door member to be disposed, during at least a part of a non-transport period, the length of the gap region is set to be greater than or equal to the second interval, and the shield gate is in the closed state, and, during the transport period, the shield gate is in the open state, and the length of the gap region is set to a first interval that is shorter than the second interval.

Article transport facility

A picking system is realized that can efficiently perform operations from collection to delivery of articles in a limited space. A picking system () includes: a multi-row sorting device () configured to sort the article into one of the plurality of rows of exits () and discharge the sorted article; a container supporting device () capable of supporting an accommodating container (B) on a plurality of rows of container supporting portions () until an article group that is a set of articles for the order is collected; and a transport device () configured to unload the accommodating container (B) in which the article is accommodated from the container supporting portion (), and load an empty accommodating container (B) to the container supporting portion ().

In a picking facility, if both a first picking operation and a second picking operation are performed based on order information, a third container is transported from a housing portion to a second picking portion, a fourth container is transported from the housing portion to the second picking portion, after the second picking operation has been performed, the fourth container in which a target article has been housed by the second picking operation is transported as a second container to a first picking portion, a first container is transported from the housing portion to the first picking portion, and, after the first picking operation has been performed, the second container in which the target articles have been housed by the first picking operation and the second picking operation is transported to a shipping portion.

Picking facility

A picking system includes: a multi-column sorting device that sorts articles based on an order, and discharges each of the articles into one of a plurality of columns of compartments; a plurality of storage devices that receive the articles discharged from the respective corresponding compartments until article groups that are each a set of the articles for each order have been collected, and temporarily store the articles; and a transport device that receives and unloads the article discharged from each of the storage devices with an accommodating container located at a standby position, and loads an empty accommodating container to the standby position.
