Zusammenfassung: | To stably prevent a load collapse due to an effect of speed and acceleration during transportation.SOLUTION: In a stacker crane 3, a pair of first support members 33A and 33B can support a front side of a load W from below, the load W being placed on a support surface 29a of a slide fork 29 in a first horizontal direction. A pair of second support members 35A and 35B can support a rear side of the load W from below, the load W being placed on the support surface 29a of the slide fork 29 in the first horizontal direction. A vertical movement device 37 has a first motor 41A and a second motor 41B and moves support surfaces 33a and 35a of the first support members 33A and 33B and the second support members 35A and 35B between a lower position and an ascend position, with respect to the support surface 29a of the slide fork 29. A controller 61 controls a vertical movement device 37 so that one of the first support members 33A and 33B and the second support members 35A and 35B is located in the ascending position, depending on speed or acceleration.SELECTED DRAWING: Figure 5
【課題】搬送時の速度や加速度の影響による荷くずれを安定的に防止する。【解決手段】スタッカクレーン3において、一対の第1支持部材33A、33Bは、スライドフォーク29の支持面29aに置かれた荷Wの第1水平方向前側を下方から支持可能である。一対の第2支持部材35A、35Bは、スライドフォーク29の支持面29aに置かれた荷Wの第1水平方向後側を下方から支持可能である。上下動装置37は、第1モータ41A、第2モータ41Bを有し、スライドフォーク29の支持面29aに対して、第1支持部材33A、33B及び第2支持部材35A、35Bの支持面33a、35aを下降位置と上昇位置との間で移動させる。コントローラ61は、速度又は加速度に応じて、第1支持部材33A、33B及び第2支持部材35A、35Bの一方を上昇位置に位置するように上下動装置37を制御する。【選択図】図5 |
