Definitions

  • the invention relates to a device for superimposing paper sheets or the like, with a longitudinal traverse arrangement, by means of dikes, the paper sheets lying in parallel rows in a paper running plane in a paper running direction in the direction of the rows are successive in an assembly.
  • ⁇ in ⁇ r arranged below the paper running plane, associated with a row, lower vacuum traction unit, over which two sheets of paper coming from different rows can be placed in pairs, and with a transporting device, by means of which the pairs of sheets are simultaneously transferred from one another ⁇ b ⁇ i
  • the vacuum transport is an endless conveyor belt provided with perforations, which has two deflection rollers mounted in a carrier and a vacuum chamber arranged between them is guided, which is open to the upper working strand of the conveyor belt adjoining the paper running plane.
  • the device according to the invention is used for superimposing sheets of paper, for example forms, which a cutting machine outputs in a two-use mode.
  • a known device of the type mentioned at the outset according to DE 3k 33 7 A1 serves a similar purpose. In this known device, they are conveyed one after the other into the collating state in two rows of paper sheets. There is a cross G Z to the direction of the paper, over ⁇ ine vacuum - 2 -
  • a paper sheet coming from the first row of paper sheets can be moved transversely to the direction of the paper, the other already in the assembly station, which is pushed by the second sheet of paper originating from the paper sheet. Leaching the transverse transport of the paper sheet must not only stop the other paper sheet, but also the feeding of further paper sheets must be interrupted. Only when the two papers in the collation station are completely overlaid, can they be removed from the collation by means of a paper direction in the direction of paper rotation.
  • the vacuum trap unit is sy metrically arranged in the middle between the two sheets of paper and the conveyor belt can optionally be driven in the same or another direction.
  • paper sheets from the first row of paper sheets can be chosen from the first row of paper sheets over paper sheets from the second row of paper sheets and vice versa ⁇ erd ⁇ .
  • this known device operates discontinuously in time, ie the paper sheet feed and removal must be interrupted for the time, which is necessary to shift the paper sheet in the collating station. This results in a relatively long cycle time and a correspondingly low level of output. The clockwise operation of the device also causes greater noise. Furthermore, several stop bars are required in the assembly station in order to ensure the precise alignment of the paper to be moved transversely. 3 -
  • the invention is therefore based on the task of creating a device for overlapping paper sheets or the like of the type mentioned, which is characterized above all by high performance, thereby working precisely and reliably, in the case of formatting, requiring a number of changeover operations, and requiring multiple operations is adjustable.
  • That the other row of paper sheets is assigned at least one similar, upper vacuum transport unit, above the paper runner, from which the lower working area of the conveyor belt to the paper running area and the vacuum chamber is open to the lower working area.
  • the invention thus starts from the thought that the paper sheets coming from each sheet of paper are assigned a respective vacuum vacuum, of which the vacuum sheet row assigned to the vacuum transport row is arranged below and the other paper sheet is assigned to the other paper sheet above.
  • the invention is based on the idea of arranging the vacuum - tra ⁇ sport ⁇ i ⁇ h ⁇ it ⁇ -n so that its tra ⁇ sp ⁇ rt baths run essentially in the direction of the paper travel direction and the adjustment of the position of the conveyor belts is possible with the adjustment direction using the adjustment direction.

  • UJ ⁇ it ⁇ r ⁇ ⁇ tri ⁇ bsw ⁇ is ⁇ n d ⁇ r ⁇ u ⁇ device are further explained below using the drawing. It is essential to the new device that the inclination of the conveyor belt or the conveyor belt across the paper running direction means that the paper sheets can be continuously overlaid.
