  • Automated warehouse rack
    Patent number: 9296559
    Abstract: Shelf parts of a rack apparatus for an automated warehouse include a hollow placement member and a stopper. The placement member is fixed to a rack main body and has a placement surface onto which an article is placed. The stopper is disposed at an end part of the placement member and restricts vibration of the article in a first horizontal direction. The stopper includes a base member fixed to the placement member, a projection member having a projection extending higher than the placement surface, and a viscoelastic member connecting the base member and the projection member within the placement member. The viscoelastic member generates a damping force when the viscoelastic member is deformed by the shear in the first horizontal direction.
