Abstract

The invention relates to a method and a device for processing flat mailings, according to which two or more piles of mailings, the destination addresses of which are known and which are sorted according to the distribution order, are separated by means of a separating device (3), are directed onto a common transport path (4), and are then jointly stacked in the order in which the mailings have been transported. The separation process is timed in such a way that the joined mailings are transported on the transport path (4) in the order in which they are to be distributed based on the known destination addresses. A unit (6) detecting the destination addresses on the mailings and a sensor arrangement (7) detecting the leading and trailing edges of the mailings are disposed along the transport path (4). The mailings are then separated via a separating element (8) onto two following transport paths (9, 10) which are rejoined at the ends thereof, at least one of said transport paths (9, 10) being provided with a braking/accelerating module (11,12). The mailings that succeed each other upstream from the separating element (8) are moved towards each other if the detection unit (6) detects a reversed order in the flow of mailings such that the mailings are redirected in the correct order while a minimum distance is maintained between the mailings downstream from the junction in order for the mailings to be stacked.

Description

  • Die Erfindung betrifft ein Verfahren und eine Einrichtung zum Verarbeiten von flachen Sendungen nach den Oberbegriffen der Ansprüche 1 und 5.The invention relates to a method and a device for processing flat items according to the preambles of claims 1 and 5.
  • Beim automatischen Sortieren von flachen Sendungen auf einer Sortiermaschine nach der Verteilreihenfolge in mehreren Durchläufen müssen im Normalfall sämtliche vom Zusteller an einem Tag zu verteilenden Sendungen hintereinander in die Sortiermaschine eingegeben werden. Dazu wird aber ein relativ großes Zeitfenster benötigt. Ist dieses nicht vorhanden, so muss schon vorher ein Teil der angelieferten Sendungen nach der Verteilreihenfolge sortiert werden und danach erfolgt die Sortierung des Restes der angelieferten Sendungen nach der Verteilreihenfolge. Dann werden die beiden vorsortierten Stapel zu einem einzigen in der Verteilreihenfolge sortierten Stapel zusammengeführt. Dazu wird jeder Stapel wieder vereinzelt. Die Vereinzelung erfolgt so, dass die in einem Transportstrang zusammengeführten Sendungen in der Verteilreihenfolge transportiert werden. Dieser Transportstrang mündet in eine Stapeleinrichtung, in der durch kontinuierliches Abstapeln ein oder mehrere Teilstapel mit Sendungen in der Verteilreihenfolge erzeugt werden.
    Durch Vereinzelungsfehler, z.B. Doppelabzüge, oder Fehlsendungen kann es durch die aufgrund der bekannten Zieladressen der vorsortierten Stapel vorgegebene Abzugsreihenfolge zu falschen Reihenfolgen im zusammengeführten Sendungsstrom und gesamten Folgestapelabschnitt kommen.
    Mit einer nach den Vereinzelungseinrichtungen am Transportpfad angeordneten Erkennungseinheit zur Ermittlung der Zieladressen kann diese Fehlsortierung erkannt werden. Die falsch postierten Sendungen werden dann in ein Sonderfach sortiert und müssen anschließend manuell in den erzeugten Stapel einsortiert werden.
    Damit möglichst wenige Sendungen als falsch postiert in das Sonderfach sortiert werden, sollte die Erkennungseinheit möglichst dicht an der Vereinzelungseinrichtung angeordnet sein. Dies ist aber nur eingeschränkt möglich, da sich vor einer kostengünstigen Erkennungseinheit immer eine Richtstrecke befinden muss, d.h. die Mindeststrecke zwischen Vereinzelungseinrichtung und Erkennungseinheit beträgt ungefähr 2 m.
    Das hat wiederum zur Folge, dass beim Erkennen eines Fehlers die sich schon in der Richtstrecke befindlichen Sendungen nicht mehr beeinflussbar sind und manuell in den sortierten Stapel eingefügt werden müssen, was kosten- und zeitintensiv ist.
    In the case of automatic sorting of flat items on a sorting machine according to the distribution order in several passes, it is normally necessary to enter all items to be distributed by the deliverer in one day in succession into the sorting machine. But this requires a relatively large time window. If this is not available, then a part of the delivered consignments must already be sorted according to the distribution order and then the sorting of the remainder of the consignments delivered ensues according to the distribution order. Then, the two presorted batches are merged into a single stack sorted in the distribution order. For this purpose, each stack is separated again. The separation takes place in such a way that the consignments merged in a transport line are transported in the order of distribution. This transport strand opens into a stacking device, in which one or more partial stacks are produced by means of continuous stacking with items in the distribution order.
    Due to separation errors, for example double copies, or incorrect mailings, due to the deduction sequence prescribed on the basis of the known destination addresses of the presorted piles, incorrect orders in the combined mail stream and the entire subsequent stack section may occur.
    With a detection unit arranged on the transport path after the singulation devices for determining the destination addresses, this mis-sorting can be detected. The wrongly posted programs are then sorted into a special subject and then have to be manually sorted into the generated stack.
    To ensure that as few items as possible are sorted incorrectly into the special compartment, the recognition unit should be arranged as close as possible to the separating unit. However, this is only possible to a limited extent since there must always be one straightening line in front of a low-cost detection unit, ie the minimum distance between separating device and detection unit is approximately 2 m.
    This in turn means that upon detection of an error, the shipments already in the route are no longer influenced and manually inserted into the sorted stack, which is costly and time consuming.
  • Der Erfindung liegt daher die Aufgabe zugrunde, ein Verfahren und eine Vorrichtung zu schaffen, bei denen zwei oder mehrere nach der Verteilreihenfolge sortierte Stapel von Sendungen, deren Zieladressen bekannt sind, in einem Transportpfad in der Verteilreihenfolge zusammengeführt und dann zusammen abgespeichert werden und mit deren Hilfe bei Vereinzelungsfehlern
    oder Fehlsendungen die Anzahl der manuell in den sortierten Stapel einzuordnenden Sendungen reduziert wird.
    The invention is therefore based on the object to provide a method and an apparatus in which two or more sorted by the distribution stack of shipments whose destination addresses are known, combined in a transport path in the distribution order and then stored together and with their help with singulation errors
    or misses the number of shipments manually sorted into the sorted stack will be reduced.
  • Erfindungsgemäß wird die Aufgabe durch die Merkmale der Ansprüche 1 und 5 gelöst.According to the invention the object is achieved by the features of claims 1 and 5.
  • Nach der Erkennungseinheit am gemeinsamen Transportpfad und der die Sendungskanten detektierenden Sensoranordnung werden die Sendungen über eine Weiche auf zwei nachfolgende Transportpfade aufgeteilt, die an ihren Enden wieder zusammengeführt werden. Mindestens einer der beiden nachfolgenden Transportpfade weist ein Brems-Beschleunigungsmodul auf. Ermittelt die Erkennungseinheit eine vertauschte Reihenfolge der Sendungen, so werden die entsprechenden, vor der Weiche aufeinander folgenden Sendungen im Sendungsstrom gegeneinander so verschoben, dass die Sendungen nach der Zusammenführung in der richtigen Reihenfolge unter Einhaltung einer Mindestlücke zwischen den Sendungen zur Abstapelung weiter transportiert werden. Dadurch müssen Sendungen mit vertauschter Reihenfolge nicht mehr manuell wie die Doppelabzüge und Fehlsendungen einsortiert werden.After the detection unit on the common transport path and the sensor edge detecting sensor, the programs are divided over a switch on two subsequent transport paths, which are brought together again at their ends. At least one of the two subsequent transport paths has a brake acceleration module. If the recognition unit determines a reversed order of the shipments, then the corresponding shipments in the shipment stream which follow one another in turn before the switch become mutually exclusive shifted so that the consignments are transported after the merge in the correct order, while maintaining a minimum gap between the packages for stacking. As a result, consignments with a reversed order no longer need to be sorted manually, such as double deductions and incorrect mailings.
  • Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen dargelegt.Advantageous embodiments of the invention are set forth in the subclaims.
  • So ist es für die Einhaltung möglichst kleiner Lücken zwischen den Sendungen vorteilhaft, wenn sich in beiden nachfolgenden Transportpfaden Brems-Beschleunigungsmodule befinden. In dem einen Transportpfad wird bei vertauschter Reihenfolge die im Sendungsstrom jeweils führende Sendung mittels eines dort befindlichen Bremsbeschleunigungsmoduls im Sendungsstrom nach hinten und in dem anderen Transportpfad die jeweils nachfolgende Sendung mit dem dort befindlichen Brems-Beschleunigungsmodul nach vorn verschoben.
    Zur Unterstützung der Verschiebung nach vorn ist der entsprechende nachfolgende Transportpfad vorteilhaft kürzer als der Transportpfad für die nach hinten zu verschiebenden Sendungen. Dadurch sind die entsprechenden Sendungen schon um den Längendifferenzbetrag nach vorn verschoben.
    Soll eine kostenreduzierte Variante realisiert werden, so ist es vorteilhaft, wenn der nachfolgende kürzere Transportpfad für die nach vorn zu verschiebenden Sendungen ohne Brems-Beschleunigungsmodul ausgeführt ist. Damit sich in diesem Fall beim Verschieben keine Überlappungen ergeben, muss die erforderliche Lücke Lerf entsprechend größer als die Minimallücke Lmin sein.
    Dabei ergibt sich
    die erforderliche Lücke Lerf = 0,5 *(2 * Lmin+ Smax - Smin)
    mit
  • Smax =
    maximale Sendungslänge
    Smin =
    minimale Sendungslänge.
    Thus, it is advantageous for compliance with the smallest possible gaps between the programs when brake acceleration modules are located in both subsequent transport paths. In the one transport path, the consignment in the respective leading consignment by means of a braking acceleration module located there in the shipment stream to the rear and in the other transport path, the respective subsequent program with the brake acceleration module located there moved forward.
    To support the shift forward, the corresponding subsequent transport path is advantageously shorter than the transport path for the shipments to be moved backwards. As a result, the corresponding items are already shifted forward by the difference in length.
    If a cost-reduced variant is to be realized, then it is advantageous if the subsequent shorter transport path for the forwardly to be shifted transmissions is executed without brake acceleration module. Thus, in this case, no overlaps when moving, the required gap L erf must be correspondingly larger than the minimum gap L min .
    This results
    the required gap L erf = 0.5 * (2 * L min + S max - S min )
    With
    S max =
    maximum shipment length
    S min =
    minimum shipment length.

  • Für jeden der zwei nach der Verteilreihenfolge sortierten Stapel von flachen Sendungen ist eine Stoffeingabe 1 vorgesehen. Die Sendungen werden auf das jeweilige Feederbett 2 gestellt und mittels eines Unterflurbandes und einer mit ihm lösbar gekoppelten Stütze, die den Stapel aufrecht hält, zur Vereinzelungseinrichtung 3 transportiert. Diese Vereinzelungseinrichtungen 3 ziehen die jeweils vorderste Sendung vom Stapel ab und befördern sie über eine Zusammenführung in einen Transportpfad 4, der als Deckbandsystem ausgeführt ist. In den Transportpfad 4 integriert ist eine Ausrichtstation 5, damit die Sendungen in definierter ausgerichteter Lage eine nachfolgende Erkennungseinheit 6 passieren, mit der die Zieladressen auf den Sendungen gelesen werden. An dem Transportpfad 4 folgt dann eine Sensoranordnung 7 - als Lichtschranke ausgeführt - zur Detektion der Vorder- und Hinterkanten der Sendungen, damit die Schaltzeitpunkte einer Weiche 8 und die gesteuerten Abläufe von Brems-Beschleunigungsmodulen 11,12 unter Wahrung der festgelegten minimalen Lücken zwischen den Sendungen vor dem Einstapeln durch die Steuerung festgelegt werden können. Diesem Transportpfad 4 schließen sich über die Weiche 8 zwei nachfolgende Transportpfade 9,10 an, die jeweils ein Brems-Beschleunigungsmodul 11,12 aufweisen. In jedem Brems-Beschleunigungsmodul 11,12 können Sendungen je nach Notwendigkeit durch Abbremsen und ggf. Abstoppen im Sendungsstrom nach hinten oder durch Beschleunigen im Sendungsstrom nach vorn verschoben werden, wobei dem Verschieben nach vorn Grenzen gesetzt sind. Zur Verschiebung dieser Grenze ist der Transportpfad 11, in dem die Sendungen nach vorn verschoben werden, kürzer als der andere Transportpfad 12 ausgeführt. Beide Transportpfade 11,12 werden über eine Zusammenführung vereinigt.For each of the two stacks of flat mail items sorted according to the distribution order, a material input 1 is provided. The broadcasts are placed on the respective feeder bed 2 and transported to the separating device 3 by means of an underfloor belt and a support which is releasably coupled to it and which holds the stack upright. These separating devices 3 remove the respective foremost consignment from the stack and transport it via a merge into a transport path 4, which is designed as a shroud system. Integrated into the transport path 4 is an alignment station 5, so that the programs pass in a defined aligned position a subsequent recognition unit 6, with which the destination addresses are read on the programs. At the transport path 4 then follows a sensor arrangement 7 - designed as a light barrier - for detecting the leading and trailing edges of the programs, so that the switching times of a switch 8 and the controlled operations of brake acceleration modules 11,12 can be set while maintaining the specified minimum gaps between the programs before stacking by the controller. This transport path 4 is followed by the switch 8, two subsequent transport paths 9,10, each having a brake acceleration module 11,12. In each brake acceleration module 11,12 programs can be moved as needed by braking and possibly stopping in the broadcast stream to the rear or by accelerating in the broadcast stream forward, with the move forward limits are set. To shift this limit, the transport path 11, in which the mail items are moved forwards, is executed shorter than the other transport path 12. Both transport paths 11, 12 are combined via a merge.
  • In den FIG 2 - 4 wird der Verschiebeprozess näher dargestellt.
    Unter "Soll" ist in FIG 2 und 4 mit den Pfeilen und den in ihnen befindlichen Zahlen angegeben, in welcher Reihenfolge die beiden Stapel auf Basis der übermittelten Soll-Zieladressen vereinzelt werden müssen, d.h. zuerst die vorderste Sendung "1" des oberen Stapels, dann die vorderste Sendung "2" des unteren Stapels, dann die folgende Sendung "3" des oberen Stapels usw. Bei ordnungsgemäßen Vereinzelungsabläufen würde sich die dargestellte Reihenfolge im Sendungsstrom ergeben.
    Werden aber vom oberen Stapel die ersten beiden Sendungen "1" und "3" als Doppelabzug zusammen abgezogen, so würde auf Grund der bekannten Sollinformation bezüglich der Zieladressen wie unter "Korrektur" dargestellt weiter vereinzelt werden. Wenn dieser Doppelabzug diagnostiziert wird, befinden sich schon die dargestellten zehn Sendungen (FIG 2) im Transportpfad, d.h. wie zu erkennen müssten alle abgezogenen Sendungen später manuell eingefügt werden, da sie sich nicht in der Verteilreihenfolge im Sendungsstrom befinden. Werden aber durch Verschieben entsprechende Vertauschungen durchgeführt, so ergibt sich der unter "Ergebnis" dargestellte Sendungsstrom und es muss nur der Doppelabzug (Sendungen "1" und "3") ausgeschleust und manuell eingeordnet werden. Das Verschieben erfolgt so, dass die nach vorn zu verschiebenden Sendungen um die minimale Lücke plus der Länge der vor der Verschiebung davor platzierten Sendung verschoben und die nach hinten zu verschiebenden Sendungen um die minimale Lücke plus der Länge der vor der Verschiebung dahinter platzierten Sendung verschoben wird.
    In Figures 2 - 4, the shift process is shown in more detail.
    Under "target" is indicated in Figures 2 and 4 with the arrows and the numbers contained in them, in which order the two stacks must be separated on the basis of the transmitted target destination addresses, ie first the foremost program "1" of the upper stack, then the foremost program "2" of the lower stack, then the following program "3" of the upper stack, etc. With proper singulation operations, the order shown would be in the broadcast stream.
    But if the first two programs "1" and "3" are deducted from the top stack together as a double deduction, so would be further isolated on the basis of the known target information regarding the destination addresses as shown under "Correction". If this double deduction is diagnosed, the illustrated ten consignments (FIG. 2) are already in the transport path, ie, as would have been the case, all withdrawn consignments would later have to be inserted manually because they are not in the distribution sequence in the consignment stream. However, if appropriate exchanges are carried out by shifting, this results in the delivery stream shown under "Result" and only the double deduction (shipments "1" and "3") has to be rejected and manually sorted. The shifting is done so that the programs to be shifted forward are shifted by the minimum gap plus the length of the program placed before the shift, and the programs to be shifted backward are shifted by the minimum gap plus the length of the program placed before the shift ,
  • In der FIG 3 wird dieser Ablauf mit der Besonderheit dargestellt, dass vier Sendungen "4,6,8,10" vom unteren Stapel hintereinander aufgrund der Sollinformation zu den Zieladressen abgezogen werden sollen.
    Werden wieder die ersten beiden Sendungen "1,3" des oberen Stapels als Doppelabzug abgezogen, so werden die Sendungen aufgrund der Sollreihenfolge wie unter "Korrektur" dargestellt vereinzelt. Um zur richtigen Reihenfolge zu gelangen, erfolgt das Verschieben nach vorn der vier Sendungen "4,6,8,10" wie in FIG 2 beschrieben, nur die eine Sendung "5" muss in die Lücke vor der Sendung "7" zurückgeschoben werden (durch entsprechend langes Abstoppen im Brems-Beschleunigungsmodul).
    Aus der Darstellung der Reihenfolge der Sendungen nach dem Verschiebeprozess im "Ergebnis" ist zu erkennen, dass nach dem Doppelabzug "1,3" sich alle Sendungen in der richtigen Reihenfolge gemäß der "Soll"-Angaben befinden.
    In FIG. 3, this procedure is illustrated with the special feature that four programs "4, 6, 8, 10" are to be subtracted one after the other from the lower stack on the basis of the target information to the destination addresses.
    If the first two items "1.3" of the upper stack are deducted again as a double deduction, the items are separated due to the order of order as shown under "Correction". In order to arrive at the correct order, the forward shifting of the four programs "4, 6, 8, 10" takes place, as described in FIG. 2, only one program "5" must be pushed back into the gap before the program "7" (FIG. by correspondingly long stopping in the brake acceleration module).
    From the representation of the order of the programs after the shift process in the "result" can be seen that after the double deduction "1.3" all shipments are in the correct order according to the "target" information.
  • In der FIG 4 ist der Verschiebeablauf dargestellt, wenn nur in einem nachfolgenden Transportpfad ein Brems-Beschleunigungsmodul für die Verschiebung nach hinten angeordnet ist und der andere Transportpfad zur Realisierung einer konstanten Verschiebung Sfix nach vorn entsprechend kürzer als der mit dem Brems-Beschleunigungsmodul ausgestattete Transportpfad ist.In FIG 4, the shift sequence is shown, if only in a subsequent transport path, a brake acceleration module for the rearward movement is arranged and the other transport path to realize a constant displacement S fix forward correspondingly shorter than the equipped with the brake acceleration module transport path is.
  • Die konstante Verschiebung nach vorn Sfix ergibt sich zu Lerf + Smin mit Lerf = erforderliche Lücke zwischen den Sendungen beim Abzug.The constant displacement to the front S fix results in L erf + S min with L erf = required gap between the transmissions on the trigger.
  • Smin = minimale Sendungslänge,
    wobei die erforderliche Lücke Lerf gemäß der Beziehung L erf = 0 , 5 ( 2 L min + S max S min )
    Figure imgb0001
    gegenüber der minimalen Lücke Lmin vergrößert ist.
    (Smax = maximale Sendungslänge).
    Die Verschiebung der langen Sendung "5" nach hinten ist S 5 = L min + S max ( S max = S 5 )
    Figure imgb0002
    und der kurzen Sendung "7" nach hinten S 7 = S max + L erf ( zulässig wäre noch S max + L min ) .
    Figure imgb0003
    S min = minimum transmission length,
    wherein the required gap L erf according to the relationship L erf = 0 . 5 * ( 2 * L min + S Max - S min )
    Figure imgb0001
    is increased relative to the minimum gap L min .
    (S max = maximum transmission length).
    The shift of the long program "5" to the rear is S 5 = L min + S Max ( S Max = S 5 )
    Figure imgb0002
    and the short broadcast "7" to the rear S 7 = S Max + L erf ( would still be permissible S Max + L min ) ,
    Figure imgb0003
  • Um den Durchsatzverlust mit einer solchen Anordnung etwas zu reduzieren, besteht die Möglichkeit, die Abzugslücke als Funktion der vorauslaufenden Sendungslänge zu erzeugen.In order to reduce the throughput loss with such an arrangement somewhat, it is possible to generate the deduction gap as a function of the leading length of the shipment.
  • Eine Verarbeitung von mehr als zwei Sendungsstapeln erfolgt in für den Fachmann klarer analogen Art und Weise und muss daher nicht näher beschrieben werden.A processing of more than two consignment stacks takes place in a manner that is clear to a person skilled in the art and therefore does not need to be described in more detail.

Method for processing flat mailings, in which two or more stacks of mailings sorted in distribution order, whose destination addresses are known, are in each case separated by means of a separating device (3) and led into a common transport path (4) and are then stacked together in the transport order, the separation of the stacks being timed in such a way that the combined mailings are transported in the transport path (4) in the distribution order on the basis of the known destination addresses, a detection unit (6) for determining the destination addresses on the mailings and a sensor arrangement (7) detecting the leading and trailing edges of the mailings being arranged on the transport path (4), in which the mailings are subsequently divided up via a diverter (8) to two subsequent transport paths (9, 10), which are led together again at their ends and of which at least one has a braking/accelerating module (11, 12), the mailings following one another before the diverter (8), in the event of a transposed order in the mailing stream determined by the detection unit (6), being displaced with respect to one another in such a way that, after being led together, the mailings are transported onward in the correct order to be stacked, while maintaining a minimum gap between the mailings.
  2. Method according to Claim 1, in which, in the event of a transposed order, the mailing respectively leading in the mailing stream in one of the two subsequent transport paths (10) is displaced rearward in the mailing stream by means of a braking/accelerating module (12) located there and, in the other subsequent transport path (9), the respectively following mailing is displaced forward in the mailing stream by means of a second braking/accelerating module (11) located there.
  3. Method according to Claim 1, in which the subsequent transport path (9) for the mailings to be displaced forward is shorter than the transport path (10) for the mailings to be displaced rearward.
  4. Method according to Claim 3, in which the subsequent transport path (9) for the mailings to be displaced forward has no braking/accelerating module and the minimum gap Lerf required in this case is given by the relationship l erf = 0.5 - ( 2 * L min + S max - S min ) ,
    Figure imgb0004
    where
    Lmin = minimum gap;
    Smax = maximum length of a mailing;
    Smin = minimum length of a mailing.
  5. Device for processing flat mailings, in which two or more stacks of mailings sorted in distribution order, whose destination addresses are known, are brought together in the correct sequence in the distribution order to form a mailing stream, are transported and then stored in the transport order, in each case having a separating device (3) for each stack and a common transport path (4) connected to the separating devices (3), the separation of the stacks proceeding in such a way that the combined mailings are transported in the transport path (4) in the distribution order on the basis of the known destination addresses, a detection unit (6) for determining the destination addresses on the mailings and a sensor arrangement (7) detecting the leading and trailing edges of the mailings being arranged on the transport path (4), in which the common transport path (4) is connected via a diverter (8) to two subsequent transport paths (9, 10), which are led together again and of which at least one has a braking/accelerating module (11, 12), it being possible for the diverter (8) and the braking/accelerating module or modules (11, 12) to be driven in such a way that the mailings following one another before the diverter (8), in the event of a transposed order determined by the detection unit (6), are displaced with respect to one another in such a way that, after being led together, the mailings are transported onward in the correct order to be stacked, while maintaining a minimum gap between the mailings.
  6. Device according to Claim 5, in which the subsequent transport path (9) for the mailings to be displaced forward is shorter than the transport path (10) for the mailings to be displaced rearward.
  7. Device according to Claim 5, in which the subsequent transport path (9) for the mailings to be displaced forward is designed without a braking/accelerating module.
