Abstract:
1. A cassette insertion control method for transferring a cassette held by a picker to a storage section partitioned by a pair of side plates through a front opening part of a garage, the cassette insertion control method comprising: a first step of moving the picker in a horizontal direction such that a vertical center axis serving as a center when the cassette held by the picker rotates approaches a target stop position deviated from a center position of the front opening part of the garage; a second step of rotating the cassette held by the picker about the center axis such that the cassette is tilted with respect to the storage section of the garage without opposing the storage section of the garage; a third step of allowing the cassette to approach the storage section such that a first tip corner part of the tilted cassette enters the storage section through the front opening part of the garage; a fourth step of further rotating the tilted cassette about the center axis in a direction that the first tip corner part of the cassette comes into contact with the side plate in a state that a second tip corner part of the cassette is prevented from coming into contact with the side plate; a fifth step of allowing the cassette to further approach the storage section; a sixth step of moving the picker in the horizontal direction such that the cassette held by the picker approaches the center position; and a seventh step of pushing out the cassette toward the storage section, thereby to transfer the cassette from the picker to the storage section.
