  • Patent number: 11873165
    Abstract: A movement apparatus is provided that moves an article in a transfer direction. The movement apparatus is provided with a first protruding/retracting unit, a second protruding/retracting unit installed in a state spaced apart from the first protruding/retracting unit in the width direction, a first drive unit that moves the first protruding/retracting unit in the width direction, and a second drive unit that moves the second protruding/retracting unit in the width direction. The first drive unit is configured to move the first protruding/retracting unit in the width direction within a first setting range by swinging a first connection unit, and the second drive unit is configured to move the second protruding/retracting unit in the width direction within a second setting range wider than the first setting range by moving a second connection unit back and forth in a prescribed path.

  • Patent number: 10815054
    Abstract: An article transport apparatus includes a mast provided upright on the traveling body, an upper frame (6) coupled to an upper end portion of the mast and an upper rail (R2) that guides movement of the upper frame (6). Separately from guide rollers disposed on lateral opposite sides of the upper rail (R2), a first roller (18A) and a second roller (18B) that are rotatable about vertical axes (P1, P2) are disposed on opposite sides of the upper rail (R2). A first supporting member (19) supporting the first roller (18A) is attached so as to be biased by a first biasing body (22) in a direction to push the first roller (18A) against the upper rail (R2), and a second supporting member (20) supporting the second roller (18B) is attached so as to be biased by a second biasing body (22) in a direction to push the second roller (18B) against the upper rail (R2).

  • Patent number: 7949423
    Abstract: An article storage facility includes a controller for controlling operation of a plurality of mobile bodies. The controller is constructed switchable between a total operation mode for causing all of the mobile bodies to engage in an article transporting operation for transporting articles between storage units and an article support, and a partial operation mode for causing part of the mobile bodies to engage in the article transporting operation. In the partial operation mode, a mobile body not selected as mobile body for the article transport operation is caused to travel to a retreating position clear of a traveling range of a mobile body selected as the mobile body for the article transport operation.
