Definitions

  • the invention relates to a sucker, in particular a vacuum cleaner to capture and lift each top sheet from a sheet stack, with one elastic bellows caused by negative pressure its interior from its relaxed state is contractible into a shorter length and that with its upper end on a sucker body is attached, the front side facing the bellows forms a bottom of the interior of the bellows, as well as with a suction nozzle that can be subjected to negative pressure, has the suction openings, which to a suction surface guide the suction nozzle and follow the suction surface flow outside.
  • suction nozzle train as an insert component and on the lower one Attach the end of the bellows by tying it in.
  • the object of the invention is therefore a sucker to create the kind mentioned at the outset from a minor Number of components, easy to assemble and repels the second sheet in double sheet detection.
  • the arc causes a relative movement of the two detected arches and thus repelling them of the second sheet detected.
  • the free end of the bellows can align well with the surface of the sheet stack, which is also a deviation of the suction cup from a vertical one Alignment to the sheet stack surface enables.
  • the rejection of the second detected sheet continues reinforced when the suction surface of the suction nozzle is a has a shape deviating from a level, since then the form of the suction surface deviating from a plane when in contact of the bow raised by the bellows on the suction surface another relative movement of the two arches Double sheet detection causes. Safe repelling or not accepting the second sheet allows very high Running speeds of a sheet feeder, its part the sucker can be.
  • the deviation of the suction surface from one level can be caused by the most diverse elevations or depressions can be reached at the suction surface.
  • the suction nozzle can be a separate, on the Front side of the suction body attachable component be interchangeable and use the optimal suction nozzle.
  • the suction nozzle advantageously has a replacement a protruding on its side facing away from the suction surface Approach on the corresponding recess can be used in the front of the vacuum body is.
  • the suction nozzle can be used with your Approach snaps into the recess of the suction body his.
  • this is preferably the Approach cylindrical and points to his free end one or more radially protruding Lugs on which in a corresponding recess Can be snapped into the recess of the sucker body are.
  • latching attachment is or also a radially circumferential ring approach if the recess has a radial circumferential groove is.
  • sucker body is a cylindrical fastener has, on the cylindrical lateral surface a radially circumferential annular groove is formed is in which the upper end of the bellows with a corresponding peripheral edge can be inserted.
  • the sucker shown in Figure 1 has a fixed or movably arranged suction body 4 with a Mounting flange 19 and one down on it extending cylindrical fastening part 16.
  • a suction bore extends coaxially through the fastening part 16 20, which can be connected to a vacuum source and at the lower end of the fastening part 16 opens outwards via a suction nozzle 6.
  • the suction nozzle 6 In the recess 11 is the suction nozzle 6 with a corresponding one cylindrical approach 10 used. On radially circumferential ring approach 12 at the free end of the Approach 10 is engaged behind the bottom 21, wherein the suction bore 20 is an annular groove 13 for Snap the ring approach 12 forms.
  • Suction nozzle 6 has a larger diameter than that Recess 11 and lies on the outer end face 5 of the Fastening part 16.
  • the inside of the bellows 1 of the suction nozzle 6 protruding part of the suction nozzle 6 has a convex surface, which forms a suction surface 8 of the suction nozzle 6.
  • suction nozzle 6 7 There are three axially continuous suction openings in the suction nozzle 6 7 formed from the suction hole 20 to Guide the interior 2 of the bellows 1 and on the suction surface 8 flow into these.
  • the three suction openings 7 flow evenly on a concentric pitch circle distributed in the interior 2.
  • the last section 14 at the free end 9 of the bellows 1 is designed as a flexible ring lip 15. On this ring lip 15 is subjected to negative pressure the suction hole 20 and the interior 2 of the top arc of a stack of sheets. This will open up of the bellows 1 closed and another Evacuation of this contracted, causing the captured Sheets separated from the sheet stack and up to the system the suction surface 8 of the suction nozzle 6 is raised.
