Definitions

  • the invention relates to a sorting device for flat objects, for example sheets or stacks of sheets containing gaps between them having conveyor rollers for conveying the objects on a conveyor path and reading means arranged at a distance from the conveying path for recognizing at least a sorting criterion on the items.
  • European patent application 0 616 857 relates to a method and a device for distributing objects, in particular flat trained.
  • a roller conveyor on which the objects to be distributed are transported is arranged in roll sections from groups Rolls divided with window sections in between. Below the window sections are secondary conveyors for the sorted out Objects arranged.
  • Unwinding devices are located above the roller conveyor, which are lowered to one of the roller sections in a controlled manner can, so that the object lying on it against the conveying direction of the roller conveyor rolls and through the window section behind falls on the secondary conveyor located under this window section. Rolling the objects backwards into the window sections ensures that that the objects are placed almost horizontally on the secondary conveyor become.
  • This device is particularly for sorting objects determined with a certain mass, such as magazines, compact discs or the like. On the other hand, it is not suitable for single sheets of light material, such as Paper.
  • European patent application 0 829 310 there is a device shown to discharge flat consignments, which are also on a Transport route based on rollers.
  • the transported shipments are from above with a cover strap guided by pressure rollers against the Transport level pressed.
  • a switch wing the surface of which in the Transport plane lies and which is pivotable perpendicular to the transport plane.
  • the turnout wing there is one perpendicular to the transport level Movable pulley, which covers the cover strap and the switch wing the transport plane deflects so that one between the cover strap and the switch wing consignment lying in an area below the following Transport role is directed.
  • the switch wings towards can pass from the pivot point to the free edge with this device the toasting described above does not occur.
  • this device is in particular because of the turnout wing and the cover strap complex.
  • the present invention is based on this prior art based on the task of proposing a sorting device which does not have the disadvantages mentioned and moreover much easier is constructed as the devices known from the prior art.
  • This object is achieved in that at a distance from the conveying path in the conveying direction after the reading means deflection rollers are arranged one behind the other by actuating means in the conveying path are movable and that at a distance from the conveyor path relative to the deflection rollers Trays to hold the distracted and objects are passed between two conveyor rollers.
  • the embodiment according to claim 2 allows a particularly simple and inexpensive manufacture and control.
  • the embodiment according to claim 5 allows a particularly quick and easy removal of the objects sorted by means of the device.
  • the measure specified in claim 6 is intended to ensure that the items to be sorted out are in the phase in which they be distracted from the conveyor, be transported safely.
  • claim 8 provides an embodiment of the inventive Sorting device in front, with which also thicker and less sorted flexible items such as stacks of sheets or booklets can be.
  • an embodiment of an inventive Sorting device shown as part of a document management system.
  • 1 shows a schematic side view of the entire system.
  • 1 is a separating device, which holds a stack of documents to be sorted by the system.
  • the documents are moved with a belt conveyor 2 transported on the right, where they pass a reading device 3, which in the present Example is designed as an OCR reading head on the documents recognizes printed characters and as a sorting criterion to a control device 4 transmitted.
  • Documents on the sorting line where they are carried by conveyor rollers 5 and to be transported further.
  • the conveyor rollers can also be paired or in groups be wrapped in conveyor belts.
  • each deflection roller 7 is located below the Funding path a storage compartment 10, in which the according to a certain criterion sorted documents are included.
  • Storage container 20 and 21 provided, one of which, for example Sorting out a larger number of documents can serve which have to be subjected to a further sorting later and the other one Can be used to hold documents for which there is no sort criterion could be read.
  • FIG. 2 shows a detail from FIG. 1 on an enlarged scale.
  • the pneumatic cylinders 8 attached to the frame 9 can be seen through which the deflection rollers 7 in the direction of the transport rollers 5 are movable.
  • One of the pneumatic cylinders, namely the one with 8 ' designated, is shown in the extended state, so that the associated Deflection roller 7 'together with the relevant conveyor roller 5' a document 11 between the conveyor roller 5 'and the subsequent conveyor roller down in the corresponding storage compartment 10 'redirects.
  • the storage compartments 10 are through Partitions 12 are formed and are open at the bottom.
  • the ones stored in the storage compartments Documents come in on their front edge in the transport direction stand, namely on a sliding floor 13, which is perpendicular to the conveying direction can be pulled out of the system from the side. Since the partitions 12th take an angle of less than 90 ° to the horizontal, such as shown in Fig. 2, the documents stored in the storage compartments fold after pulling out the sliding floor 13 to the left and form lying Groups such as are shown in FIG. 5, for example.
  • the sliding floor 13 can with a friction-increasing coating, for example made of rubber, be provided so that the documents standing in the storage compartments 10 easily can be pulled out sideways.
  • FIG Fig. 2 again enlarged and greatly simplified section illustrates. It can be seen in this figure that document 11, which is based on the im Clockwise rotating transport rollers 5 was introduced, through the deflecting roller 7 'moved downward between the latter and the transport roller 5' deflected and between the transport roller 5 'and the transport roller 5' 'after is led below.
  • the rollers are arranged so that the deflection roller 7 'can touch the transport roller 5', but not the transport roller 5 ''.
  • FIG. 4 shows a schematic cross section of the sorting device seen a view of the deflection rollers in the conveying direction, the Pneumatic cylinder in the extended position and thus the deflection rollers 7 are shown in their lower position, in which they have the corresponding conveyor roller touch.
  • the upper position is indicated by dashed lines.
  • the Transport rollers 5 are mounted on both sides in side parts 19 which are hollow are and receive the belt 6 driving the conveyor rollers 5, but which is not shown in this figure.
  • the pneumatic cylinders are on frame 9 8 attached, each carrying a bracket 15 in which an axis 14 receiving the deflection rollers 7 is mounted.
  • the fork-shaped Bracket 15 is designed so that its downwardly extended side elements 16 simultaneously form a longitudinal guide for the documents.
  • Fig. 6 shows a second embodiment of the inventive Sorting device with which not only individual documents, but also small batches or booklets can be processed. Experiments have been carried out with such a device stack with up to 200 documents without interference sorted.
  • the conveyor rollers 5 are nearby the deflection rollers 7 slidably mounted so that they counter to the force of Springs 23 under the pressure of the deflection rollers 7 towards the storage compartments 10 are displaceable. This ensures in particular that the Stack while deflecting from the conveyor path with a much larger one Radius can be bent as the documents described above Design of the device. Short and stiff objects can be used with the 6 are even sorted out without being bent become.
  • the reference numeral 22 indicates a slot in which the Axis of the conveyor roller 5 in the side part 19 is vertically displaceable.
  • the pneumatic cylinders 8 must have a larger stroke than in the embodiment according to FIGS. 1 to 5 further to provide means that allow the conveyor rollers in the to move downward shifted position. But this is part of general knowledge of the expert and is therefore not further described here.
