Abstract: The invention relates to a vacuum grip system (10) for gripping at least one object (11a). The vacuum grip system (10) has a base unit (18) and at least two suction units (19, 20) affixed thereto, disposed at right angles to one another, and each having at least one suction gripper (21, 22). At least one of the suction units (19, 20) grasps the object or objects (11a) to be gripped from above, and at least one of the suction units (19,20) grasps the object or objects (11a) from one side. In order to provide The vacuum grip system (10) having maximum flexibility, it is proposed to affix the suction units (19, 20) to the base unit (18) such that, in order to grip the object (11a), the distance between the upper suction unit (19) and the lateral suction unit (20) may be varied. It is further proposed that the vacuum grip system (10) have a mechanical undergripper (25) upon which the gripped object (11a) may be laid.

Abstract: A block suction apparatus for fixing plate-shaped work pieces on a fixing beam or fixing table using under-pressure has at least one support surface provided with a sealing plate having a sealing lip about its periphery. The sealing lip delimits a suction chamber and least one supporting element is provided within the suction chamber. At least one additional supporting element is also provided and is located in the direct vicinity of the sealing lip. Sagging of sections of a plate being lifted by the apparatus which project past the block suction apparatus is thereby reduced and the edge of the plate can therefore be processed with greater accuracy.

Abstract: Vacuum manipulation apparatus includes a lifting hose coupled to a vacuum-generating unit. The lifting hose incorporates a suction gripping device having a suction end adapted for placement against an object to be grasped and lifted. The device includes a flow opening plate adapted to be opened for preventing an abrupt rise of the gripping device upon unintentional release of the grasped object against gravitational forces. In a non-grasping mode, a retractable, spring-loaded push rod extends from the suction end of the device. The push rod retracts whenever the suction gripping device engages a grasped object. A blocking arm attached to the push rod engages the flow opening plate to hold the plate normally closed during the grasping mode. When suction is broken between the grasped object and the suction end of the gripping device, the push rod extends from the device, however, opening the flow opening plate to admit airflow.

Abstract: A vacuum holding apparatus with at least one base and a suction unit supported by the base, on which the workpiece to be held can be placed and is vacuum-held by the suction unit, wherein the suction unit has a first gripping surface on the side facing the workpiece, and a second gripping surface on the side facing the base wherein the suction unit is provided with at least one mechanical holding mechanism for attachment to the base.

Abstract: The invention concerns a vacuum handling device comprising a lifting hose (4), which can be connected to a vacuum generating device (12), and a suction gripping device (6) which can be disposed on an object to be handled and with which the object can be suctioned or lifted through retraction of the lifting hose (4), wherein the suction gripping device (6) is provided with a handle (18) for an operator for manipulating the device during proper use, and wherein the suction performance of the vacuum generating device (12) and the associated vacuum prevailing in the lifting hose (4) can be set in a remotely controlled fashion.

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.
