Definitions

  • the invention relates to a vacuum generator device with at least one ejector unit, one with a feed connection connected jet nozzle, one downstream of the jet nozzle Catch nozzle and one in the transition area between the Jet nozzle and the capture nozzle defined, via a suction channel has a suction zone connected to a suction connection, and with a pressure monitoring unit that connects to the suction channel connected pressure sensor.
  • a vacuum generator device known from DE 3818381 A1 this type has a device housing which is an ejector unit contains and attached to the outside several components are, among which there is also the pressure in the suction channel monitoring pressure monitoring unit is located.
  • the dimensions this vacuum generator device are relatively large, so that it is hardly suitable for handling directly on one of suction cups serving objects become.
  • the connection to the suction pad is therefore regular manufactured via a separate line.
  • the pressure monitoring unit is expediently in one referred to as the sensor receiving chamber receiving chamber of the device housing housed, the assembly by the Realization of a housing cover is greatly simplified.
  • the housing cover can be used to make the sensor receiving chamber accessible in the event of a defect a quick exchange of the pressure monitoring unit is possible.
  • the ejector unit 2 contains a jet nozzle 7 with a Jet nozzle channel 8 and a catch nozzle 12 with a catch nozzle channel 13.
  • the jet nozzle 7 and Catch nozzle 12 are expediently inserted axially.
  • the ejector unit 2 has an elongated shape.
  • the ejector unit 2 is coaxial with the preferably cylindrical one Ejector receiving chamber 5 inserted.
  • the plug-in assembly happens through an extension of the ejector chamber 5 trained mounting opening 14 of the device housing 4, in which a supply connection 15 defining connecting device 16 is fixed.
  • the feed connection 15 thus communicates with the jet nozzle 7.
  • Die Connection device 16 is designed to connect one with a Connect pressure source connectable compressed air line under seal to be able to.
  • the mentioned suction pad with its open side is ahead attached to the outer surface of an object to be handled, after which the space mentioned is suctioned off and evacuated, so that a negative pressure arises, which clings to the object effected on the suction pad.
  • the object can be placed in any position Position way.
  • the room to be evacuated is ventilated again.
  • optical display means 37 are provided are to display at least one operating state of the Serve vacuum generator device 1.
  • the display means 37 consist of a light guide which in the ejector chamber 5 is inserted and at least there is opposite a lighting element 38 whose light is thus clearly visible to the outside.
  • the two units 2, 3 lie together in one with the Major axis 42 coinciding major plane of the device housing 4, which is identical to the drawing level. rectangular
  • the vacuum generator device 1 builds a lot narrow. It is particularly provided that the feed connection 15, the suction connection 23 and the electromechanical Interface 33 lie in this main plane and in the direction of expansion the main level are aligned.
  • the suction connection 23 points in the main plane mentioned Page.
  • the one that is also preferably in the main level Outlet opening 17 is conveniently located on the front outside 45 opposite rear outside 46 of the device housing 4.
  • the setting means 35 and the display means 37 are expedient arranged on the removable housing cover 52.
