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.
