Definitions

  • the invention relates to a device and a method for feeding flat goods to a processing unit, the flat goods being arranged one behind the other in a lying position and transported by means of a transport device.
  • the panels which are transported lying one behind the other, hit the positioning marks or stops during their transport, so that the panels are forced into the desired or precise position. Finally, an optimal longitudinal alignment of the panels with respect to the transport route is necessary so that they are fed to the processing process or the processing unit at the right time. Since the panels have increasingly smaller sheet thicknesses and ever higher production speeds are required, damage to the panel edges can often occur with the known devices.
  • the panels When separating and feeding panels from the feeder to the processing unit, the panels must be transferred at an exact angle to ensure smooth and shock-free panel movement, which is ultimately also a prerequisite for a good fit on the processing unit.
  • the panel transport to the processing unit using friction-dependent transport means is influenced, among other things, by the condition of the transport means, the difference in speed between two transport systems, the coefficient of friction of the underside of the panel, the production speed and the inertia of the panels.
  • An alignment device in which the side edge of a sheet is detected by light barriers in order to determine its position relative to a target printing position.
  • a conveyor device and a method for conveying sheets of printing material are known, with the leading edges of the printing material being aligned with stop surfaces of a cylinder.
  • the DE 100 13 006 A1 discloses a device for driving a pre-gripper for the individual transport of sheets from a feed table to a gripper system of a further cylinder.
  • the pre-gripper has sheet detection elements that can be driven by an electric linear drive.
  • the DE 198 14 141 C2 discloses according to the preamble of claim 1 a device for precisely positionally feeding sheet-shaped goods to a processing unit by means of a transport device.
  • the transport device has two transport means that are spaced apart from one another and can be driven independently of one another to correct the skew and can be moved transversely to the transport direction to align the goods sideways.
  • the DE 101 36 872 A1 discloses a device for aligning sheets on a feed table of a sheet processing machine with front marks for aligning sheets transported in a conveying direction with the front edge against the front marks.
  • the invention is based on the object of creating a device and a method for feeding flat goods to a processing unit, which reduces the mechanical load on the flat goods even at high processing speeds and which, in particular, enables high feeding accuracy.
  • the advantages that can be achieved with the invention are, in particular, that the flat goods are fed to a processing unit without any shocks. Another advantage is, in particular, that the feeding of flat goods takes place with greater precision. Alignment errors when separating a stack or feeding errors, which can be caused by aggregates that are arranged upstream of the device for feeding sheet-shaped goods, are corrected. Embodiments of the invention are shown in the drawings and will be described in Described in more detail below.
