Abstract: A vacuum manipulation device with a lifter hose, which can be connected to a vacuum-generating device, and with a suction gripper device, which can be placed on an object to be manipulated, by means of which the object can be drawn-up and, by contracting the lifter hose, can be lifted. In order to prevent the suction gripper device from snapping upward in case of an unintentional release of a drawn-up object, the manipulation device features a weight-actuable regulating element which, under the effect of the weight of an object drawn by suction against the suction side of the suction gripper device, blocks a flow cross section into the interior of the lifter hose, and unblocks it in the unoccupied state of the suction gripper device.

Abstract: The present invention relates to a vacuum handling apparatus, having a suction gripper device which can be connected by means of a lifting hose to a vacuum-creating device and can be placed upon an object, in order to suck up the object for lifting or conveyance. The apparatus has a control valve for controlling the vacuum prevailing in the interior of the suction gripper device and in the lifting hose, in order to lift or lower the suction gripper device with a sucked-up object or the empty suction gripper device, or to deposit a sucked-up object.

Abstract: A vacuum lift device comprising a lift tube which is able to contract and expand in an upward and downward direction, and a lift tube expansion control valve controlling the opening areas of the atmospheric openings of the lift tube. A hovering control valve controlling the flow area between the second atmospheric opening and the interior of the lift tube is provided. The lift tube expansion control valve is normally positioned at a position such that is completely covers the first atmospheric opening, and the second atmospheric opening is open to the outside space. At this time, the level of vacuum in the lift tube is adjusted by the hovering control valve so that an object to be lifted is maintained at a desired height.
