Article transfer device

An article transfer device comprising:

• an article supporting portion that supports an article from below;
• a first guide portion and a second guide portion that oppose each other in a first direction extending along a horizontal plane, across the article supported by the article supporting portion;
• a base that supports the article supporting portion, the first guide portion, and the second guide portion;
• and
• an article movement mechanism for moving the article relative to the base along a second direction orthogonal to the first direction on the horizontal plane, wherein:
• the article supporting portion, the first guide portion, and the second guide portion are supported by the base so as to be movable in the first direction, and
• the article transfer device further comprises:
• a guide movement mechanism for moving the first guide portion and the second guide portion independently along the first direction;
• and
• an interlocking mechanism for interlocking movement of the first guide portion and the second guide portion along the first direction with movement of the article supporting portion such that the article supporting portion is located midway between the first guide portion and the second guide portion in the first direction,
• the interlocking mechanism includes a first rotational body rotatably supported by the article supporting portion, and a first movement portion and a second movement portion that are connected to the first rotational body so as to move to sides opposite to each other along the first direction following rotation of the first rotational body, and
• the first movement portion is connected so as to move integrally with the first guide portion along the first direction, and the second movement portion is connected so as to move integrally with the second guide portion along the first direction.
