Definitions

  • the invention relates to a method for grouping sheet units belonging together in sheet groups in a sheet stream comprising two sheet units lying one above the other according to claim 1, a grouping unit according to the preamble of claim 9 and a sheet handling system according to the preamble of claim 14.
  • Sheet handling systems are known from the prior art which, in addition to a sheet feeding device, e.g. a cutting device, which provides individual sheet units arranged next to one another from a paper web, which are then transported to a collecting device for collecting the individual sheet units, a merger.
  • the merger which is arranged downstream of the sheet feeding device in the sheet travel direction, represents a paper merging device.
  • the sheet units lying one on top of the other, forming the sheet stream are then transported into the collecting station, in which the sheet units are collected. If all sheet units that belong together, a so-called sheet group, are deposited in the collecting station, the stack formed from them is output from the collecting station.
  • the stack output from the collecting station can be further processed, e.g. folded and/or enveloped, in a device downstream of or connected to the collecting station.
  • the individual sheet groups can include an even or an odd number of sheet units. It is also possible that consecutive leaf groups comprise different numbers of leaf units. It is also possible that a sheet group consists of only one sheet unit.
  • the sheet units of a sheet stream provided by the sheet feeding device and guided one above the other by the merger do not necessarily belong to the same sheet group.
  • stacked sheet units that do not form a sheet group belong are fed separately to the collection station, for which purpose the flow of sheets is temporarily stopped. This results in a reduction in the clock performance of the sheet handling system.
  • a method and a device for forming sheet groups from a plurality of sheet units or sheets are known, with a sheet feeding device providing two single sheets arranged next to one another, which are transferred to a merger.
  • the merger guides the single sheets one on top of the other and transfers them to a stopping point device upstream of the collecting station.
  • the stopping point device serves to transfer the single sheets into the collecting station. If the single sheets arranged one above the other do not belong to a common sheet group, the single sheet belonging to a subsequent sheet group is held back while the other single sheet is transferred to the collecting station. After the sheet group arranged in the collecting station has been carried out, the single sheet held back in the stopping point device is transferred to the collecting station.
  • A1 document processing and document sorting apparatus having at least one document feeder having one or more document collection bins for receiving a series of documents fed in spaced groups.
  • the object is to provide an improved method for grouping sheet units belonging together in sheet groups of a sheet flow comprising two sheet units lying one above the other, as well as an improved grouping unit and sheet handling system that enable a high process speed or a high cycle output of a sheet handling system.
  • the method preferably includes the exit of a complete group of sheets from the collecting station before the entry of a new group of sheets into the collecting station.
  • the sheet units are thereby transported through the grouping unit or as long as from the Grouping unit retained that they only reach the collection station when the collection station is ready to receive a new group of sheets.
  • Sheet units arranged one above the other from the same sheet group are, as described above, transported together through the grouping unit into the collecting station. If the sheet units arranged one above the other do not belong to the same sheet group, initially only one of the two sheet units is transferred to the collecting station. The other sheet unit is retained in the grouping unit and, depending on the following sheet units or their association with the sheet group of the sheet retained in the grouping unit, is transferred to the collecting station alone, with one or with both following sheet units. Except for the case of a sheet group consisting of only a single sheet unit held back in the grouping unit, there is a continuous transfer of the sheet units arranged one above the other into the grouping unit and from there into the collecting station.
  • the individual retained sheet unit is to be transported from the grouping unit to the collection station ready for receiving before the sheet units to be subsequently transferred into the grouping unit are transferred.
  • the transfer of the individual sheet unit to the collecting station is only limited by the transfer of the preceding sheet unit to the collecting station and the moving out of the sheet group arranged in the collecting station, and thus the time for preparing the collecting station for receiving a new sheet group.
  • the process according to the invention is preferably continued after process steps b), i) and ii) with process step a).
  • process step iii) the process, as described above, is continued with one of process steps i) to iii). This results in a continuous method for complete processing or grouping of a sheet stream comprising two sheet units lying one on top of the other or for processing all sheet units provided by the sheet feeding device.
  • the sheet units are assigned correctly to the respective sheet group.
  • the sheet units to be subsequently transferred into the grouping unit are arranged above or below a sheet unit retained in the grouping unit, depending on the arrangement sequence of the subsequent sheet units or the collecting direction of the sheet units and/or the arrangement of a sheet unit retained in the grouping unit.
  • This enables the sheet units of the sheet stream belonging to a sheet group to be correctly lined up or collected. If only one of the following sheet units is part of the sheet group of the sheet unit retained in the grouping unit, the other sheet unit can be arranged in such a way that retention of this sheet unit in the grouping unit is possible.
  • the sheet unit to be retained is not arranged between the sheet units belonging to a common sheet group.
  • the grouping unit has a suction device, via which a sheet unit is retained in the grouping unit.
  • a Suction device is a targeted retention of a sheet unit to be retained of the sheet stream consisting of two sheet units arranged one above the other until it is combined with one or both sheet units to be subsequently transferred into the grouping unit or, if necessary, until the individual sheet unit is transferred into the collecting station ready for receiving.
  • the grouping unit preferably includes a first transport unit upstream of the suction device and/or a second transport unit downstream of the suction device. The sheet units are fed into the suction device via the first transport unit and the sheet units are transported from the suction device into the collecting station via the second transport unit.
  • the speed at which the sheet units pass through the grouping unit can also be determined via the transport units.
  • the retention of a sheet unit can be supported by the first transport unit.
  • the one to three sheet units are transferred from the suction device to the collecting station via the second transport unit.
  • the suction device particularly preferably consists of a lower and an upper suction plate.
  • the designations used above and below relate in each case to an element arranged above or below a sheet running plane (or the central plane of the sheet flow).
  • a shingled arrangement of the stacked sheet units ie slightly offset in sheet travel direction, to hold back the upper sheet unit by the lower suction plate.
  • the lower sheet unit Irrespective of the arrangement of the stacked sheet units of the sheet stream transferred into the grouping unit, this enables the sheet units to be lined up correctly in the grouping unit and thus the collection direction to be maintained.
  • a transport unit upstream and/or downstream of the suction device not only increases the speed at which the sheet units are transferred to the grouping unit or from the grouping unit to the collecting station, it is also possible to retain a sheet unit in the grouping unit.
  • a sheet unit to be retained can be braked by the transport unit upstream of the suction device and the transfer of sheet units into the suction device can be controlled.
  • a transport unit downstream of the suction device a targeted transfer of the sheet units to be transferred from the suction device into the collecting station, in particular under Taking into account a sheet unit to be retained in the collection station.
  • the transport units can also be used to control the speed at which the sheet units are transferred into the grouping unit or from there into the collecting station.
  • the sheet units have an identifier that indicates the affiliation of the sheet units to a sheet group.
  • the identifier for example an OMR code (optical mark recognition)
  • OMR code optical mark recognition
  • the sheet units are transferred into the grouping unit, in particular before the merger in the sheet feeding device.
  • This makes it possible to control the grouping unit, the merger (e.g. to control a shingled or non-shingled arrangement of the sheet units) and/or the collection station for proper grouping of the sheet units into the associated sheet groups.
  • the sheet units it is also possible for the sheet units to be assigned to a sheet group in advance, i.e.
  • the sheet units which are arranged one above the other and are to be transferred into the grouping unit, are arranged shingled in the direction of sheet travel, ie slightly offset from one another in the direction of sheet travel.
  • the sheet units provided by the sheet feeding device and arranged next to one another in the direction of sheet travel are thereby guided in a shingled manner on top of one another by the merger.
  • the shingled arrangement of the leaf units occurs through a slowed movement or a brief retention of one of the two leaf units in the merger.
  • the shingled arrangement of the sheet units transferred into the grouping unit makes it possible to retain a sheet unit in the grouping unit in a particularly simple and advantageous manner.
  • a sheet unit can be held back by a suction device and the sheet units arranged one above the other can be moved at different speeds by a transport unit.
  • only those sheet units lying one above the other that do not belong to the same sheet group are arranged in a shingled manner belong.
  • a shingled arrangement of the sheet units belonging to a sheet group arranged one above the other is not expedient, since these are anyway transferred to the collecting station together, ie without holding back one of the two sheet units in the grouping unit. This avoids an unnecessary delay, which can occur as a result of the merger arranging the sheet units in a shingled manner. In addition, this facilitates the transport of the sheet units that belong together through the grouping unit into the collecting station.
  • the method preferably includes the exit of a complete group of sheets from the collecting station before the introduction of a new group of sheets into the collecting station.
  • sheet units from different sheet groups are not mixed up in the collecting station.
