Definitions

  • the invention relates to a method for picking up individual flat, air-permeable structures from a stack, in which the individual structures are picked up by means of a vacuum lifter, brought to a processing point and put down there again.
  • vacuum lifters require that the structures that are to be inserted mechanically, for example, as paper or textile samples in measuring devices or as individual pieces in finishing or printing machines, are the same in their properties, in particular in their porosity and density. However, if the individual structures vary in these properties, their perfect absorption is no longer guaranteed. With a certain setting of the siphon vacuum, it is no longer ensured due to the varying air permeability of the structures that only one sample or one piece is ever taken.
  • DE-A-3 102 321 which corresponds to the preamble of claim 1, describes a method and a device for lifting and depositing the uppermost layer of a stack of flat, air-permeable structures by means of suction nozzles in a processing machine, wherein before lifting or Loosen after placing the top layer of the stack is squeezed. This is intended to prevent the stack from moving and to ensure that the uppermost layer can be lifted off or put down safely. With varying air permeability of the structures, however, their individual intake is also not ensured here.
  • the present invention is accordingly based on the object of developing a method for picking up individual flat structures from a stack, in which a reliable individual recording is ensured regardless of the nature of the structures.
  • the sheet-like structures are stacked with a sheet of air-impermeable material in each case in a method of the type described at the outset.
  • the flat structures such as paper or textile disks or sheets, are stacked in alternating sequence with sheets which consist of an air-impermeable material, for example plastic or metal foil.
  • the stack serves as a supply for those to be supplied with the structures Processing sites such as measuring devices or finishing or printing machines.
  • the individual structures are brought there with the aid of a vacuum lifter in coordinated swiveling and lifting movements.
  • the vacuum of the lifter is set so that the intermediate layer sheet is also sucked in even in the case of less porous structures.
  • the smaller sized sheet falls into a correspondingly sized opening in the base after the negative pressure has been switched off. The structure and the intermediate layer are thus separated again.
