Definitions

  • the invention relates to a sheet feeder for isolated feeding of sheets in one work cycle a conveyor, with one each top sheet of a sheet stack in its in the conveying direction rear area capturing and approximately vertical separating element lifting to drag vacuums, whereby the raised bow on its upward Area can be grasped by the drag vacuum and stretched Alignment approximately parallel to the stack surface in Direction of conveyance of the onward conveyor can be fed is, as well as with a presser foot, which during the further conveyance of the bow by the teats and / or the conveyor above the rear area of the sheet stack can be moved downwards towards it is.
  • Such a sheet separating device is very rich in components built and requires especially for the Press foot a complex kinematics.
  • the object of the invention is therefore a sheet feeder of the type mentioned at the outset, which consists of a few simple movements executing components is.
  • the separating element is the presser foot, which is in the work cycle approximately vertically between a stack near the surface and is movably drivable in a raised position and one approximately parallel to the stack surface in the conveying direction has directed nozzle which during the movement path from the position close to the stack surface Compressed air can be applied to the raised position and the one above their air outlet an inflow surface extending in the conveying direction owns.
  • This configuration allows for Vacuum cleaners are completely dispensed with because of Press foot now both the separation and lifting function as also performs the hold function.
  • the presser foot is no longer the one lifted by the suction cup Dodge arch backwards, but can in driven simple vertical up and down movement become what is possible using simple kinematics is.
  • the sheets are recorded and lifted in a particularly gentle manner, which in particular when processing thin sheets or sheets sensitive surface is advantageous and in considerable Avoid rejects.
  • the gentle treatment of the bow also helps that the smaller number of sheet transfers to a larger one Smoothness of the transported sheet leads.
  • a particularly gentle lifting of the top sheet is achieved in that the nozzle during its Lifting movement from a certain distance to Compressed air can be applied to the stack surface.
  • the nozzle can be approximately parallel to the Slit-like air outlet opening extending over the stack surface exhibit.
  • a safe lifting of the bow over its whole Area from the sheet stack and a perfect feeding of the bow with its front end in the conveying direction becomes a conveyor in a simple way achieved in that the raised by the presser foot Arch through directed in the direction of further conveyance Blown air is underblown or that the through the suction cups bended through in the conveying direction directed blowing air is sub-inflatable.
  • teats form a pair of teats, of which one vacuum cleaner each on one side in the conveying direction is arranged next to the presser foot, so is certainly avoided blowing air from the blow nozzles on the Top of the arch. Furthermore, can the presser foot between the suction cups shortly after without collision with the vacuum cleaners Further transport of the sheet begins on the Lower the sheet stack.
  • the suction surfaces of the drag vacuums are preferred approximately in the same plane parallel to the stack surface arranged.
  • the conveyor can be a conveyor roller and have a clock roller arranged in parallel above it, between that of the blowing air from the stack surface raised front end in the conveying direction of the top bow is insertable. It will evenly stretched front end of the raised bow safe and flawless between conveyor roller and Clock roll introduced.
  • the presser foot can be placed vertically on the sheet stack, its height position can be detected when touching down and a corresponding signal from the control unit Stacking device feedable, so it is done by the Presser foot in addition to the functions of separating and lifting of the top bow and holding onto the following top sheet of the sheet stack also the fourth function of detecting the height level of the top sheet of the sheet stack.
  • the sheet feeder shown in the figures applies a lifting table, not shown, which can be driven a sheet stack 1.
  • a blowing air nozzle 7 is arranged through which blowing air in Conveying direction 2 between the top sheets of the sheet stack 1 and one lifted by the presser foot 3 and on Drag vacuum 8 passed sheet 9 is blowable.
  • vacuum cleaner pairs 10 and 11 are in the work cycle drivable in and against the conveying direction 2.
  • a conveyor roller 12 In the conveying direction 2 in front of the sheet stack 1 are parallel to the front edge of a conveyor roller 12 and above a clock roller 13 is arranged, which is a conveyor form and between that in the conveying direction 2 front end of the conveyed by the teats 8 Bow 9 is insertable. Furthermore is in front of the front a bow flap 14 is arranged at the upper end of the sheet stack 1, that in the work cycle between a vertical and a position inclined in the conveying direction 2 is drivable.
  • the presser foot 3 is in contact on the rear end portion of the sheet stack 1 and can so feel its height level.
  • This information will via lines, not shown, of a control unit fed, which is also a stack lifting device, not shown so controlled that the top arc the sheet stack 1 is always on a certain Level is located.
  • the presser foot 3 has a small amount of the stack surface 5 is lifted off and through its nozzle 4 blown air is blown in the conveying direction 2. Thereby creates a suction effect that the top bow to Attachment to one via the air outlet opening 6 in the conveying direction 2 inflow surface 15 extending outward of the presser foot 3 attracts.
  • the drag vac 8 move with the raised Sheet 9 according to Figure 4 in its front Position and guide the front end of the sheet 9 between conveyor roller 12 and clock roller 13.
  • the presser foot 3 is on the sheet stack 1 lowered and holds the upper sheet of the sheet stack 1 firmly.
