Abstract
An advancing/retracting mechanism includes a first arm, a second arm, a first coupling part that couples the first arm and the second arm, and a second coupling part that couples a supporting body and the first arm. A transfer device is configured to move the supporting body back and forth with the first coupling part located on a first side relative to the second coupling part, by rotating the first arm and the second arm. In a first region, which is a region in the depth direction and includes an end on the front side of the rack body, a distance from the width directional center to the first supporting portion is longer than a distance from the width directional center to the second supporting portion.
Claims3
An article storage facility comprising:
- a storage rack configured to store at least one article;
- and
- a transfer device configured to transfer an article to the storage rack from a front side of the storage rack;
- wherein the storage rack includes a rack body configured to support an article from below,
- wherein, in a horizontal plane, a direction that is orthogonal to a depth direction of the storage rack is a lateral width direction, and one side in the lateral width direction is a first side, and the other side in the lateral width direction is a second side, the rack body includes, on the first side with respect to a width directional center, a first supporting portion that is formed extending in the depth direction, and, on the second side with respect to the width directional center, a second supporting portion that is formed extending in the depth direction, the width directional center being the center in the lateral width direction of the rack body, and the rack body being able to support, on both sides in the lateral width direction, a plurality of articles aligned in the depth direction using the first supporting portion and the second supporting portion,
- wherein the transfer device includes a supporting body configured to support an article from below, and an advancing/retracting mechanism configured to move the supporting body back and forth in the depth direction, an article being transferred between the supporting body and the rack body, by the supporting body being projected toward a back side of the storage rack by the advancing/retracting mechanism, and in this state, the supporting body passing through a separation space formed between the first supporting portion and the second supporting portion in a vertical direction,
- wherein the advancing/retracting mechanism includes:
- a first arm;
- a second arm;
- a first coupling part that couples the first arm and the second arm so that they can rotate about a first axis that extends in the vertical direction;
- and
- a second coupling part that couples the supporting body and the first arm so that they can rotate about a second axis that extends in the vertical direction, the second coupling part being provided at a position in the first arm that is different from a position at which the first coupling part is provided,
- wherein the transfer device is configured to move the supporting body back and forth with the first coupling part located on the first side relative to the second coupling part, by rotating the first arm and the second arm about the first axis in opposite directions, and
- wherein in a first region, which is a region in the depth direction and includes an end on the front side of the rack body, a distance from the width directional center to the first supporting portion is longer than a distance from the width directional center to the second supporting portion.
