1. An article conveying device comprising:
- a supplying section configured to convey a plurality of articles;
a discharging section configured to convey a plurality of containers each having a plurality of cells for containing the plurality of articles;
a temporary placement section having a temporary placement space on which at least one of the articles can be temporarily placed;
a first detecting section configured to detect a position and posture of the article on the supplying section at a first time point, and detect an amount of movement of the supplying section;
a second detecting section configured to detect a position and posture of the container on the discharging section at a second time point, and detect an amount of movement of the discharging section;
a working machine configured to;
take out the article by following the movement of the article on the supplying section, based on the position and posture of the article at the first time point and the amount of movement of the supplying section;
place the taken out article on the temporary placement section;
take out the article placed on the temporary placement section; and
locate the article into the container by following the movement of the container on the discharging section, based on the position and posture of the container at the second time point and the amount of movement of the discharging section; and
a controlling section configured to, when the article is positioned within an article existence judgment region defined on the supplying section and when a predicted arrival time or distance until the container conveyed by the discharging section reaches a motion range of the working machine is larger than a predetermined value, command the working machine to place the article from the supplying section to the temporary placement section, and command the working machine to locate the article from the temporary placement section into the container which has reached the motion range.
