Definitions
- US Pat. No. 5,617,898 discloses an arrangement of fluid pressure devices each having its own electronic control unit to relieve a connected sequencer.
- the fluid pressure devices may include displays to indicate malfunctions.
- the aeration time is measured, which elapses until the vacuum prevailing in the suction channel has fallen from the region of the working negative pressure to a venting pressure which is associated with releasing the previously sucked-in article.
- the aeration pressure used for the time comparison is expediently a pressure in the presence of which it can be assumed that a previously held object was normally released again.
- the venting pressure may correspond directly to the atmospheric pressure, but is conveniently a slight safety pressure below the atmospheric pressure, allowing for a more accurate measurement because the venting characteristic may leak out to atmospheric pressure in a very shallow manner, especially when operating without a discharge pulse.
- an operation with ejection pulse ie if the release of the object by an overpressure pulse controlled by a blow-off valve
- the check valve 42 is oriented so that it allows an air flow from the suction pad 7 towards the ejector 27, in the opposite direction, however, prevented. In other words, it assumes a shut-off position when the pressure applied to the side of the ejector device 27 is absolutely greater than the pressure prevailing on the side of the suction gripper 7.
- the ventilation can be assisted by this blow-off valve 5 37 or carried out alone.
- a sole venting through the purge valve 37 takes place when the check valve 42 is present.
- pressurized air flowing under pressure causes a discharge impulse via the blowout valve 37 connected in the open position lo at the connection point 28, bypassing the ejector device 27, into the suction channel 35, so that the negative pressure is reduced very rapidly and under certain circumstances even at least for a short time prevails in the suction channel 35.
