Definitions

  • the invention relates to a suction transport device for removing a sheet from a stack of sheets in a sheet running direction, which has at least two circumferential suction devices, and a method for removing sheets.
  • a sheet feeder for folding machines on which a suction transport device is provided, which has a continuously rotating suction wheel with horizontal and transverse to the sheet running direction axis of rotation.
  • a suction transport device which has a continuously rotating suction wheel with horizontal and transverse to the sheet running direction axis of rotation.
  • the invention has for its object to provide a suction transport device with structurally simple means, can be reliably removed with the sheet of different format from a stack of sheets.
  • two suction devices are mounted transversely to the sheet travel direction and horizontally adjustable. This makes it possible to reduce or increase the distance between the two suction devices depending on the size of the sheet to be removed. This ensures that sheets of various sizes are reliably and accurately transported to a further processing machine.
  • the adjustable suction devices are preferably mounted transversely to the sheet travel direction and rotatably mounted on a drive shaft so that they can be driven by a single drive.
  • a fixed suction device is provided in the middle between the adjustable suction devices, of which the adjustable suction devices each have the same distance. With such a suction transport device even the smallest bows can be safely removed.
  • the drive shaft is driven by a servomotor controlled by a control device.
  • the controller is configured to control the servo motor to apply suction to suction devices to remove a sheet from the stack of sheets, and to initially rotate the suction devices at minimum speed, then accelerate the suction devices to a maximum speed, then the maximum speed a predetermined period of time is maintained, and then the suction air is switched off and the suction devices are retarded to minimum speed.
  • the two adjustable suction devices are each formed by a suction belt and the specified suction device in the middle of a suction roll.
  • the suction transport device 10 comprises two horizontally spaced suction belts 12, 14 and arranged in the middle between the two suction belts 12, 14 suction roller 22.
  • the two suction belts 12, 14 each comprise a small roller 18 and a larger roller 16, of an endless band 20 are surrounded.
  • the rollers 16 of the suction belts 12, 14 are non-rotatably mounted on a common drive shaft 26 and can be axially displaced on the drive shaft 26.
  • a drive pinion 23 Adjacent to the suction roller 22, a drive pinion 23 is rotatably mounted on the drive shaft 26, which of a in FIG. 1
  • servomotor 30, which is shown explosively, is rotated via an endless toothed belt 28.
  • the suction belts 12, 14 and the suction roller 22 are each connected via a suction line 40 to a vacuum device.
  • FIG. 1 shown position of the suction belts 12, 14 is suitable for the decrease of smaller bow. If larger sheet formats are to be removed, the distance of the suction belts 12, 14 of the suction roller 22 can be changed by the push bar 32 is moved to the left, whereby the suction belt 12 moves to the left. The holder 25 of the suction belt 14 is then mounted on the attachment point 37. The sliding strip 32 is shifted in this case so that both suction belts 12, 14 have the same distance from the suction roller 22.
  • the servo motor 30 is driven by a control device, not shown, as in the speed-time diagram of FIG. 2 is shown.
  • the speed of the two suction belts 12, 14 and the suction roller 22 is minimal and they are acted upon by suction.
  • the suction belts 12, 14 and the suction roller 22 may also be stationary at this time.
  • the suction belts 12, 14 and the suction roller 22 are accelerated to a maximum speed up to the time t 2 . This maximum speed is then maintained until time t 4 , at which the suction air is switched off. Subsequently, the suction belts 12, 14 and the suction roller 22 are delayed until finally the initial minimum speed is reached.
  • the acceleration can also be made variable.
  • a suction roll 22 and two suction belts 12, 14 are provided.
  • other embodiments are conceivable in which only two adjustable suction belts or suction rollers are used.
