Definitions

  • the invention relates to a single sheet feeder or a device with such a single sheet feeder according to the preamble of claim 1.
  • Single-sheet feeders of various types are regularly used in devices such as Printers, copiers, faxes, etc. are required to those provided in these devices Printing device from a stack of sheets to feed single sheets, creating a orderly printing is guaranteed.
  • DE-A1-26 50 739 describes a sheet feed device of the type mentioned at the outset, in which a sheet transport device an upper stop and a stop for a sheet end face guide has, which are pivotable together.
  • corner separators two components, called corner separators, which are connected to the pivotable sheet transport device are connected.
  • the surface mentioned are in one piece with each other connected. Because the corner separator is used both as an upper stop and as a front edge stop serve the sheets, they protrude into the transport path of a feed Leaf into it. This has the consequence that when a single sheet is transported Sheet is deformed at its two front corners. Because this deformation is not defined, on the one hand it can lead to faults within the single sheet feeder to lead. On the other hand, they arise especially with sensitive sheet materials possibly kinks or pressure marks, which the recycling of the sheet to make impossible.
  • a single sheet feeder or a device with such a single sheet feeder known from DE-A1-2952671 There a device for separating the uppermost sheet of a sheet stack is shown, with a stack of sheets in a cassette and from below against one arranged transport roller is pressed, the shaft axis in a fixed distance from the cassette.
  • the sheet format is limited by the size of the cassette. It is also necessary there that the top sheet also from a corner hold-down is detected.
  • page 1295 is a single sheet feeder with a sheet transport device and a support for single sheets as well as a sheet side guide, in essentially known to the carrier, the first flat stop, in which the arrangement of the transport roller near the flat stop edge ensures that even non-aligned single sheets are aligned parallel to the stop edge and be led away in that direction.
  • CH-A-682321 is a device for feeding paper-like recording media an office machine and a method for operating the device known to adapt to a specific sheet size for larger Sheet quantities are possible.
  • the single sheet feeder is usually only able to handle this paper size to process certain sheet format.
  • Sheet formats where the sheet side length exceed the set face length cannot be processed and Sheet formats with a shorter face sheet length cause regular Faults in the sheet feeder because their orderly recording is only possible with uncertainty is. This is particularly unpleasant where individual sheets are different Size or very small editions are to be printed in changing sizes, as is not uncommon when printing labels.
  • DE-A1-20 33 126 discloses a device for removing individual sheets known from a sheet stack, in which a damping plate on the top Sheet of the sheet stack rests and the damping plate on the side of an edge plate is limited, which with its upper edge below the damping plate lies so that a gap is formed between the damping plate and the edge plate, through which a sheet can be removed.
  • the invention has for its object a single sheet feeder or a device with such a single sheet feeder according to the preamble of claim 1 to develop in such a way that with safe guidance of one to be transported Sheet a deformation of the sheet during transport through the sheet transport device is avoided.
  • the invention is based on the knowledge that on a third stop, which too transporting sheet touched on a third side, can be omitted.
  • the single sheet feeder according to the invention is characterized by a very simple one Structure from, with known facilities for adjusting the sheet format entirely be omitted.
  • the Users When operating the single sheet feeder, the Users just place the paper on the support for the cut sheets and put it on the first and second edges and then align them.
  • the transport device is pivotally arranged above the carrier, so that the top one Sheet of a stack, which by means of the carrier against the transport device is pressed to grasp and lead away safely.
  • the essential sheet detection and routing parts e.g. Transport roller, Press roll and dispensing edge
  • the dispensing edge is in Extension of the second stop separated by a clear width arranged below the press roller designed as an upper stop.
  • the swing-out angle can be used as a measure of the swing-out serve the transport device by means of a sensor in a simple manner can be detected.
  • Fig. 1 shows a single sheet feeder with a carrier designed as a platform 1 2, which along guide rails 3, in which guide pins 4 of the Carrier lie, can be performed.
  • the carrier is driven by means of of a known control motor, not shown.
  • the Sheet feeder can be part of a device, not shown, with a printing device e.g. Laser, thermal printer, etc.
  • the carrier plane 5 is perpendicular to a first stop plane 6, which in the Lies in the drawing plane, and serves as a page guide. Perpendicular to the beam level and the first stop level 6 there is a second stop 7.
  • a swiveling transport device 8 is arranged above the movable carrier, which a transport roller 9, one designed as an upper stop Press roll 10 and an extension of the second stop 7 as a dispensing edge 11 formed stop edge below the upper stop.
  • the pivot axis 12 of the transport device is perpendicular to the first stop plane 6.
  • a sensor 13 can be used as a measure of the pivoting out of the transport device the pivot angle ⁇ can be determined, which in turn as Control variable used for the carrier tracking or motor control of the carrier becomes.
  • Fig. 2 it is shown how a stack of sheets, e.g. made of paper, foils, etc. Carrier is placed, which in turn is upward (arrow) in the direction of the transport device emotional. Carrier tracking lifts the stack of sheets until the transport device is raised and the swivel angle towards zero Degree goes. The single sheet feeder is now ready for operation, as shown in FIG. 3.
  • a stack of sheets e.g. made of paper, foils, etc.
  • Carrier is placed, which in turn is upward (arrow) in the direction of the transport device emotional.
  • Carrier tracking lifts the stack of sheets until the transport device is raised and the swivel angle towards zero Degree goes.
  • the single sheet feeder is now ready for operation, as shown in FIG. 3.
  • Fig. 4 shows the view Y arranged in Fig. 3, i.e. Top view of single sheet feeder, in which a sheet is currently being removed.
  • the Drive device for the transport roller 9 behind the first stop level arranged and by means of a shaft 15 passing through the first stop plane connected to the transport roller 9. This is in the direction of transport (arrow) shortly before the second stop 7.
  • Figures 5 and 6 show enlarged detail views of the single sheet feeder in the area of the transport facility.
  • the front edge of the dispensing edge 11 lies separated from the second stop 7 in extension of the second stop 7 in a certain distance below the press roll 10.
  • the distance between the Dispensing edge and the press roll is so large that a sheet is passed between them can be.
  • the distance between the dispensing edge and the press roll is adjustable.
