The present invention relates to a vacuum manipulation device having a lifter hose, which can be connected to a vacuum-generating device, and a suction gripper device, which can be placed on an object to be manipulated and with which the object can be drawn up by suction and lifted by contracting the lifter hose, the suction gripper device has a prestressed regulating member on its suction side, which is actuated by placing the suction gripper device on the object and which thereby unblocks a flow cross-section, so that the object can be drawn up by suction. To prevent the abrupt upward acceleration of the suction gripper device, the regulating member can be arrested in its actuated position, so that in case of the release of a drawn-up object from the suction side of the suction gripper device the flow cross-section is not again blocked, and in this way the abrupt upward acceleration of the suction gripper device is prevented.

Abstract

The present invention relates to a vacuum manipulation device having a lifter hose, which can be connected to a vacuum-generating device, and a suction gripper device, which can be placed on an object to be manipulated and with which the object can be drawn up by suction and lifted by contracting the lifter hose, the suction gripper device has a prestressed regulating member on its suction side, which is actuated by placing the suction gripper device on the object and which thereby unblocks a flow cross-section, so that the object can be drawn up by suction. To prevent the abrupt upward acceleration of the suction gripper device, the regulating member can be arrested in its actuated position, so that in case of the release of a drawn-up object from the suction side of the suction gripper device the flow cross-section is not again blocked, and in this way the abrupt upward acceleration of the suction gripper device is prevented.
