A device for generating an negative pressure comprises a plurality of ejectors and a receiving device therefor. The receiving device comprises at least one connection for a compressed air line, the connection protruding into a compressed air distribution system to which a compressed air channel of each ejector can be connected, and each ejector being provided with an negative pressure channel that can be connected to the negative pressure system of the ejector. The receiving device forms a holding frame and a quick-change system for the ejectors, and can be connected to the ejectors by means of control lines, and to a machine control system.

Method and device for monitoring negative pressure loss in a negative pressure generating device

The invention concerns an underpressure surface gripping device with an extruded profile having a hollow chamber, a vacuum plate which is mounted parallel to the extruded profile, at least one flow through opening which connects the extruded profile to the vacuum plate, and with an ejector as a vacuum generator, wherein the ejector is inserted into the hollow chamber of the extruded profile and the suction opening of the ejector communicates with the flow through opening.

Underpressure surface gripping device

A vacuum gripper for suctioning work pieces, having a vacuum connection, a flexible suction body and a suction body holder, where the side of the suction body facing the work piece has a sealing lip bounding a vacuum chamber, and the vacuum chamber is connected to the vacuum connection. The suction body has a contact surface abutting the work pieces with prevailing vacuum in the vacuum chamber. The contact surface is provided with elements, where the elements are have a rod or pin-shaped configuration and form a microstructure.

Suction grip arm

The invention concerns an underpressure valve with a multi-part housing and a disc-like closing body which has at least one opening, and with an opening-free section disposed in alignment with the flow channel of the housing.

Underpressure valve

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.

Block suction apparatus

Under pressure handling device comprising an under pressure generator, a device for controlling the under pressure and several grippers which engage on a work piece to be handled, wherein each gripper is provided with a device for controlling the under pressure, a sensor for detecting state variables on the gripper and an evaluation electronics to which the device for controlling the under pressure and the sensor are connected.

Under pressure handling device

Vacuum generator comprising an ejector nozzle which is connected to a compressed-air supply via a compressed-air line, and with a first valve for opening and closing the compressed-air line, wherein a second electrical valve is connected to the suction line of the ejector which is open in the currentless state to connect a pneumatic vacuum switch, circuited in parallel with the first valve, to the suction line.

Vacuum generator with power failure operation mode

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

Vacuum grip system for gripping an object, and handling apparatus for handling an object using a vacuum grip system

A holding device for work pieces to be machined, with a fixture and a vacuum holding block which can be set on the fixture, where an automatic or remotely-controllable mechanical locking device, for holding the vacuum holding block in position on the fixture is provided.

Holding device

The present invention relates to a gripper system which can be secured to a hand of a robot and has at least two mutually independent gripper elements; each gripper element is provided with at least one force sensor for ascertaining a force in a predetermined direction. With this gripper system, it is possible to grasp components more reliably.

Gripper system, in particular vacuum gripper system

An elastic vacuum body of a vacuum gripper for suctioning workpieces comprises a sealing lip defining a vacuum chamber at a side of the vacuum body facing the workpiece. The vacuum chamber is flow-connected to a vacuum supply and ribs project into the vacuum chamber . The sealing lip comprises at least one groove on its surface facing the vacuum chamber . The vacuum body can hold oily objects without slippage. Sheet metal is securely held without distorted bending.

Vacuum gripper

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.

Vacuum manipulation apparatus

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.

Vacuum holding apparatus

The invention relates to a vacuum tightening system comprising a supporting base and a modular suction device for tightening a work piece. According to the invention, the modular suction device and the work piece can be tightened by means of a vacuum circuit in which the vacuum pressure is increased for tightening the work piece.

Vacuum tightening system

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.
