The invention relates to a lifting device comprising a lifting tube (12) connected to an adjustable vacuum source, the lifting tube (12) being attached or fixed to a suction cup (5) comprising an edge and an internal volume providing a gas-tight closure to a surface of an object during operation. The vacuum source subjects the lifting tube (12) to a low pressure, and the internal volume of the lifting tube (12) is connected to the internal volume of the suction cup (5) such that air can flow from one internal volume to the other, the vacuum source providing a lifting force when the air flowing into the lifting tube (12) is limited or shut off. The lifting device further comprises a valve unit (14) comprising a separator (15) which, in at least one position, reduces air flow between the internal volume of the lifting tube (12) and the internal volume of the suction cup (5) and, in at least one open position, allows maximum air flow between the internal volume of the lifting tube (12) and the internal volume of the suction cup (5). The valve unit (14) further comprises an actuator (6) which, during operation, controls the separator (15) between an open position allowing a maximum flow of air through the valve unit (14) and a closed position allowing a minimum flow of air through the valve unit (14).

    本发明涉及一种提升装置,包括连接到能调节的真空源的起重管(12),起重管(12)被附接或固定到吸盘(5),吸盘包括在操作期间对物体的表面提供气密封闭的边缘和内部容积部。真空源使起重管(12)承受低压,并且起重管(12)的内部容积部被连接到吸盘(5)的内部容积部,使得空气能够从一个内部容积部流动到另一个内部容积部,当流动到起重管(12)中的空气被限制或切断时,真空源提供提升力。提升装置还包括阀单元(14),阀单元包括分离器(15),分离器在至少一个位置减少起重管(12)的内部容积部与吸盘(5)的内部容积部之间的气流,并且在至少一个敞开位置允许起重管(12)的内部容积部与吸盘(5)的内部容积部之间的最大气流。阀单元(14)还包括致动器(6),在操作期间,致动器对分离器(15)在允许最大气流穿过阀单元(14)的敞开位置与允许最小气流穿过阀单元(14)的关闭位置之间的位置进行控制。
