Definitions

  • the invention relates to a device for separating flat mail, stacked at one deduction gap having vertical stop surface aligned and at a bottom edge supported by a footprint a conveyor to a take-off belt with a substantially vertical conveyor belt level are transported, whereby the trigger belt has suction openings and by friction as well Suction air on the essentially horizontal and transverse to be deducted to the direction of movement of the said funding Consignments.
  • Devices of this type are used in particular in post offices and Mail distribution centers for sorting mail items such as letters, Magazines or the like. Used.
  • the funding has subjects on, which have partitions, which the stacks to the conveyor belt transport.
  • the stacks are usually made by Hand inserted in the compartments.
  • the stacks can be very different Have shipments, such as low and narrow letters and thick, heavy magazines that also with can be packed in a plastic film.
  • a problem with these devices are double deduction errors. Here is additional deducted another shipment for the front shipment. A double deduction is due in particular to liability between two shipments or caused by rousing forces.
  • Such devices include in EP-A-0 854 103 and the further prior art.
  • the invention has for its object a device to create the type mentioned, which is characterized by fewer double deduction errors distinguished and which can still be produced inexpensively is.
  • the task is in a generic device solved that the footprint has an area that the consignments on their way to the conveyor belt level at captured lower edge and transverse to the transport direction of the conveyor fanned out. It has been shown that such Area for separating a stack that has reached the extraction gap significantly supported. Entraining forces between the preceding and the subsequent broadcast are reduced and thus reducing the likelihood of a double deduction error.
  • the fan-out effect is particularly great when according to a development of the invention, the area one Has wedge in the transport direction of said funding increases. Those promoted against the level of the conveyor belt Shipments are lifted by this wedge until they are off the conveyor belt gripped and pulled horizontally from the stack. The wedge causes vertical movement and mutual displacement of the consecutive programs.
  • the wedge points upwards Top of the ribs that extend in the withdrawal direction.
  • the ribs prevent the shipments from sliding and provide support the vertical orientation of these programs. That I the ribs extend in the withdrawal direction, the withdrawal of the Shipments are not hindered.
  • a particularly effective fanning out is achieved if said area is vibrated substantially vertically becomes.
  • the vibrations add additional to the shipments short vertical movements are practiced, which loosening up of the stack. Fanning out and loosening of the stack can also be reinforced be, if according to a training by at least an air opening for the consignments of compressed air is fed.
  • the area mentioned and in particular a wedge as the air openings mentioned can also be comparatively inexpensive can be realized and are reliable.
  • the device 1 shown in FIGS. 1 and 2 has one Funding 5, which is essentially vertical Stack 2 in the direction of arrow 7 against a trigger device 14 promotes.
  • the funding 5 is, for example endless band and has several compartments in a row, in which the stacks 2 are inserted by hand, for example. Such funding 5 are known to the person skilled in the art.
  • the stack 2 each consist of several programs 10, the for example letters, magazines wrapped in foil and are like that.
  • the consignments 10 are in accordance with FIG. 2 with a lower horizontal edge 12 on a horizontal Footprint 6 supported. With a vertical front Edge 13 are the mail items 10 on a vertical stop surface 3 aligned.
  • the stop surface 3 is, for example formed by a fixed plate 4.
  • the trigger device 14 has an endless flexible band 15 on, which is driven by a vertical drive roller 16 and at a distance from it in a likewise vertical role 17 is deflected.
  • the band 15 has a plurality of suction openings 9 on, in the area of a suction device 18 air from the outside 8 sucked into the interior of the suction device 18 becomes.
  • the suction device 18 has a suction channel 19 on that with a vacuum source, not shown here connected is.
  • a trigger gap 11 Between a vertical take-off belt level 8 and the plate 4 is a trigger gap 11, which is vertical extends.
  • a forwarding consignment 10a reaches the take-off belt level 8, it is sucked in by the belt 15 and through Friction and suction air in the direction of arrow 26 through the trigger gap 11 horizontally withdrawn from the stack 2 and for example a reading device not shown here, which controls the further route of the broadcast 10a. Subsequently the following consignment 10b is captured by the tape 15 and subtracted in the same way. Is a whole stack 2 isolated, then a subsequent one, not shown here, becomes Stack treated in the same way.
  • the wedge 20 is at least as follows wide as the trigger gap 11 and can be several at the same time Record programs 10. Support ribs 27 and grooves 28 the vertical alignment of the mail items 10.
  • the in FIG. 2 drawn angle of inclination ⁇ is preferably essential less than 45 ° and is preferably in the range of 10 ° to 20 °.
  • Seen in the withdrawal direction is located in front of the ribs 27 an ascending ramp 22 which prevents broadcasts 10 experience a resistance in trigger direction 26 on wedge 20.
  • the inclined top 21 of the wedge 20 can also be significant be shorter or longer than shown in Figure 1. You can in Figure 1, for example, from the stop surface 3 to the deflection roller 17 extend.
  • the wedge 20 can be designed differently. In the shown Execution is the inclined top 28 step-shaped increasing. An embodiment is also conceivable in which the Top 27 is formed for example by a curvature. The vertical fanning out of the mail items 10 is essential. As can be seen, the wedge 20 is arranged so that the mail items 10 seen in the pull-off direction at its front end, i.e. close to the leading edge 13, and, as mentioned, to be fanned out. Basically, the wedge 20 can also be arranged at a distance from the trigger gap 11.
