The transport system includes a transport device that transfers a green tire to and from a rack part. The transport device includes a lift stage, a support part, and a guided part. The lift stage is provided to be movable upward and downward. The support part is provided on the lift stage and supports an upper inner wall of the green tire from a lower side. The guided part is provided on the lift stage. The rack part is provided with a guide part having a lower portion defining a first gap with the guided part and an upper portion defining a second gap with the guided part.
Claims5
A transport system comprising:
- an overhead travelling vehicle that transfers an article to and from a placement part on which the article is placed,
- wherein
- the overhead travelling vehicle includes
- a lift stage that is upwardly and downwardly movable,
- a support part provided on the lift stage and supports a held part of the article from a lower side, and
- a guided part provided on the lift stage,
- the placement part is provided with a guide part that determines a planar position of the guided part, and
- the guide part has a lower portion that ensures, between the lower portion and the guided part, a first gap where the guided part moves horizontally so that the lift stage follows the article on the placement part, and an upper portion that ensures a second gap between the upper portion and the guided part to restrict horizontal movement of the guided part to prevent swinging of the lift stage.
