The invention relates to an article lifting device. When the holding unit (10) is lifted or lowered, the control unit controls the holding unit (10) in accordance with the change in diameter of the outer peripheral surface of the belt (22) wound around the drum (21) due to the winding and unwinding of the belt (22) when the holding unit (10) is lifted or lowered. A unit lifting amount, which is the amount of lifting of the holding unit (10) per unit rotation amount of the drive motor (23), within a lifting operation range, which is the height range of the holding unit (10) that performs the lifting operation is obtained, and the rotation amount of the drive motor (23) for the lifting operation is determined on the basis of the unit lifting amount.
本发明涉及物品升降装置。控制部在进行作为保持部(10)的下降动作和上升动作中的至少一个的升降动作的情况下,根据被缠绕于滚筒(21)的轮带(22)的外周面的直径因缠绕和放出而变化的情况,求出进行该升降动作的保持部(10)的高度范围即升降动作范围内的、驱动马达(23)的每单位旋转量下的保持部(10)的升降量即单位升降量,基于单位升降量而确定用于升降动作的驱动马达(23)的旋转量。
