Description

Die Erfindung betrifft ein Verfahren zum Sortieren von Sendungen auf automatischen Sortiereinrichtungen nach dem Oberbegriff des Anspruches 1.The invention relates to a method for sorting items on automatic sorting devices according to the preamble of claim 1.

Verfahren zum automatischen Sortieren von Sendungen sind aus den Dokumenten WO-A-98/17405 , DE-A-4000603 und DE-C-19911116 bekannt.Methods for automatically sorting shipments are from the documents WO-A-98/17405 . DE-A-4000603 and DE-C-19911116 known.

Bei den Postdiensten erfolgt die Verteilung der Sendungen aufgeteilt in Verteilgebiete. Jedes Verteilgebiet besitzt ein Verteilzentrum, in dem die Sendungen auf die benötigte Sortiertiefe bis zur Verteilreihenfolge für einen Zusteller sortiert werden. Die von den Kunden erstmals eingehenden Sendungen werden im Verteilzentrum zuerst gelesen, nach Verteilgebieten sortiert und dann zu den Verteilzentren der betreffenden Verteilgebiete versandt oder bei den Sendungen, die nur innerhalb dieses Verteilzentrums verteilt werden müssen, auf die benötigte Sortiertiefe feinsortiert.In the case of postal services, the distribution of shipments is divided into distribution areas. Each distribution area has a distribution center in which the shipments are sorted to the required sorting depth up to the distribution order for a deliverer. Shipments that are received by customers for the first time are first read in the distribution center, sorted by distribution area and then dispatched to the distribution centers of the distribution areas concerned, or sorted to the required sorting depth for shipments that need only be distributed within that distribution center.

Anhand der FIG 1 und 2 wird dieser Ablauf gemäß dem Stand der Technik näher erläutert. Die eingehenden Sendungen, z.B. Briefe, Großbriefe, Zeitschriften u.ä., werden in einer oder mehreren Sortiereinrichtungen vorsortiert auf die verschiedenen Verteilgebiete 1. Dazu wird online die Adresse gelesen, als erstes mit einem automatischen OCR-Leser und wenn notwendig mit Hilfe der Online-Videokodierung. Dabei muss natürlich zumindest der das Verteilgebiet kennzeichnende Teil der Adresse (Postkode bzw. Postleitzahl) eindeutig gelesen werden 2. Ist das nicht der Fall, so wird eine Identifikation (ID-Tag) aufgebracht (als Aufkleber oder direkt aufgedruckt) und die Sendung wird in ein spezielles Sortierfach (Refeed-Fach) sortiert 3. Diese Sendungen werden dann offline-videokodiert 4, ist das Ergebnis nicht zufriedenstellend, wird nochmals videokodiert. Anschließend werden die Sendungen in einem zusätzlichen Lauf vorsortiert 1.Based on FIG. 1 and 2 This procedure is explained in detail according to the prior art. The incoming items, eg letters, large letters, magazines, etc., are sorted in one or more sorting devices on the various distribution areas 1. For this purpose, the address is read online, first with an automatic OCR reader and if necessary with the help of online -Videokodierung. Of course, at least the part of the address characterizing the distribution area (postal code or postal code) must be read unambiguously. 2. If this is not the case, an identification (ID tag) is applied (as a sticker or printed directly) and the shipment is in sorted a special bin (Refeed tray) 3. These programs are then offline video-coded 4, the result is not satisfactory, is again video-coded. Subsequently, the items are presorted in an additional run 1.

Bei den auf die Verteilgebiete sortierbaren Sendungen wird dann überprüft, ob die Adresse für die erforderliche Sortiertiefe, z.B. bis zur Gangfolge des Zustellers, vollständig gelesen wurde 5. Wenn ja, werden die Sendungen in ein oder mehrere Sortierfächer für das entsprechende Verteilgebiet abgelegt 6. Wenn nein, erhält die Sendung eine Identifikation, falls sie noch keine aufweist, und wird ebenfalls in diesem Sortierfach abgelegt.
Bevor die Sendungen aus diesem Sortierfach einer Feinsortierung gemäß der geforderten Sortiertiefe unterzogen werden, müssen die unvollständig gelesenen Sendungen mit den ID-Tags offline-videokodiert werden, d.h. zum Videokodieren ist insbesondere bei den Sendungen, die in diesem Verteilgebiet verbleiben, wenig Zeit vorhanden, so dass die Anzahl der Videokodierplätze erhöht werden muss.
In the sortable to the distribution areas consignments is then checked whether the address for the required sorting depth, for example, until the sequence of delivery of the deliverer was read completely 5. If yes, the consignments are stored in one or more bins for the corresponding distribution area 6. If No, the shipment receives an ID, if it does not yet have one, and is also stored in this sort bin.
Before the consignments from this sorting bin are subjected to a fine sorting according to the required sorting depth, the incompletely read consignments with the ID tags must be offline-video-coded, ie little time is available for video coding, in particular for the mail items that remain in this distribution area that the number of video coding stations must be increased.

Der Erfindung liegt daher die Aufgabe zugrunde, ein gattungsgemäßes Sortierverfahren zu schaffen, bei dem die zum Offline-Videokodieren vor dem Feinsortieren zur Verfügung stehende Zeitspanne vergrößert wird.The invention is therefore based on the object of providing a generic sorting method in which the time available for offline video coding prior to fine sorting is increased.

Erfindungsgemäß wird die Aufgabe entsprechend der Merkmale des Anspruches 1 gelöst.According to the invention the object is achieved according to the features of claim 1.

Die zusätzliche Zeit zum Videokodieren wird erhalten, indem die Sendungen bei der Vorsortierung nach den Verteilgebieten für jedes Verteilgebiet in Endstellen, z.B. Sortierfächer, für schon vollständig gelesene Sendungen und in Endstellen für unvollständig gelesene Sendungen sortiert werden und nicht wie bisher vollständig und unvollständig gelesene Sendungen gemischt. Dadurch ist es möglich, sofort die vollständig gelesenen (OCR-gelesen und/oder online-videokodiert) Sendungen fein zu sortieren und diese Zeit zum Offline-Videokodieren der unvollständig gelesenen Sendungen zu nutzen.The additional time for video coding is obtained by dividing the programs in the pre-sorting by the distribution areas for each distribution area in terminals, e.g. Sorting compartments, for already completely read programs and in terminals for incompletely read broadcasts are sorted and mixed not as previously completely and incompletely read broadcasts. This makes it possible to fine-tune immediately the completely read (OCR-read and / or online-video coded) broadcasts and to use this time for offline video coding of the incompletely read broadcasts.

Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen dargestellt.Advantageous embodiments of the invention are shown in the subclaims.

So ist es vorteilhaft, die vorsortierten Sendungen unterteilt in vollständig gelesene und unvollständig gelesene Sendungen an die Verteilzentren jener Verteilgebiete zu transportieren, bei denen die Transportzeit kleiner als die Zeitperiode für die Feinsortierung ihrer lokalen, vollständig gelesenen Sendungen ist. In jedem Verteilzentrum wird dann die Feinsortierung der offline zu videokodierenden, unvollständig gelesenen Sendungen erst nach der Feinsortierung aller separat übersandten, vollständig gelesenen Sendungen durchgeführt. Dadurch wird ein weiterer zusätzlicher Zeitgewinn für das Offline-Videokodieren erzielt.Thus, it is advantageous to transport the presorted shipments divided into fully read and incompletely read shipments to the distribution centers of those distribution areas where the transport time is less than the time period for the fine sorting of their local, fully read shipments. In each distribution center, the fine sorting of the incompletely read programs that are to be video-coded offline is then performed only after the fine sorting of all separately transmitted, completely read programs. This provides additional time savings for offline video encoding.

Vorteilhaft ist es auch, die Feinsortierung nacheinander auf gleichen Sortiereinrichtungen durchzuführen, um die Anzahl der Sortiereinrichtungen möglich gering zu halten.It is also advantageous to carry out the fine sorting successively on the same sorting devices in order to keep the number of sorting devices as low as possible.

Um die Sortierprozesse in möglichst kurzer Zeit zu realisieren, ist es vorteilhaft, die Feinsortierung auf unterschiedlichen Sortiereinrichtungen parallel durchzuführen.In order to realize the sorting processes in the shortest possible time, it is advantageous to carry out the fine sorting in parallel on different sorting devices.

Um zusätzliche Zeit zum Offline-Videokodieren direkt vor dem Feinsortieren zu erhalten, werden bei parallelen Prozessen, d.h. Feinsortierung erfolgt auf unterschiedlichen Sortiereinrichtungen, die für einen jeweils zweiten Vorsortierlauf/Refeed-Lauf vollständig videokodierten, lokalen Sendungen vorteilhaft direkt der Feinsortierung durchgeführt.To obtain extra time for offline video coding just before fine sorting, in parallel processes, i. Fine sorting takes place on different sorting devices, which are completely video-coded for a respective second pre-sorting / refeeding run, and local mailings are advantageously carried out directly of the fine sorting.

Anschließend wird die Erfindung in einem Ausführungsbeispiel anhand der Zeichnung näher erläutert.Subsequently, the invention will be explained in more detail in an embodiment with reference to the drawing.

Die FIG 1 und 2 wurden bereits beim Stand der Technik erläutert.The FIG. 1 and 2 have already been explained in the prior art.

Gemäß der FIG 3 werden bei dem erfindungsgemäßen Verfahren die eingehenden Sendungen ebenfalls in einer oder mehreren Sortiereinrichtungen auf die verschiedenen Verteilgebiete vorsortiert 1. Dazu wird nach der Vereinzelung von jeder Sendung die Adresse gelesen. Dies erfolgt mit einem automatischen OCR-Leser und, falls dieser nicht erfolgreich ist, unter Zuhilfenahme einer Online-Videokodierung, bei welcher nur der für die Sortierung auf die Verteilgebiete notwendige Adressteil (Postleitzahl, Postkode) videokodiert wird.According to the FIG. 3 In the case of the method according to the invention, the incoming items are also sorted in one or more sorting devices onto the different distribution areas. For this purpose, the address is read after the separation of each item. This is done with an automatic OCR reader and, if this is not successful, with the aid of an online video encoding in which only the necessary address for sorting on the distribution areas address part (postcode, post code) is video-encoded.

Konnte dieser Adressteil nicht korrekt ermittelt werden 2, so erhält die Sendung eine Identifikation (ID-Tag) und sie wird in ein spezielles Sortierfach (Refeed-Fach) sortiert 3. Diese Sendungen werden dann offline videokodiert 4, bei Bedarf mit Wiederholungsschleife. Danach werden diese Sendungen in einem zusätzlichen Lauf vorsortiert. Bei den auf die Verteilgebiete sortierbaren Sendungen wird dann überprüft, ob die Adresse für die erforderliche Sortiertiefe beim Feinsortieren vollständig und eindeutig gelesen und als Barkode aufgebracht wurde 5.
Ist das der Fall, so werden die Sendungen in Fächer als Endstellen für vollständig und eindeutig gelesene Sendungen der ermittelten Verteilgebiete sortiert 11. Sowie genug Sendungen einsortiert wurden, werden sie aus den Sortierfächern entnommen (automatisch oder manuell) und der Feinsortierung zugeführt.
Wurden die Adressen nicht vollständig gelesen, wird als nächstes überprüft, ob die Sendungen schon einen ID-Tag besitzen. Wenn ja, werden sie in Fächer für unvollständig (teilkodiert) gelesene Sendungen der ermittelten Verteilgebiete sortiert 12.
Ist ein ID-Tag nicht vorhanden, so wird dieser vorher noch auf die Sendung aufgebracht 9. Anschließend erfolgt die Offline-Kodierung zum vollständigen Lesen der Adresse mit Aufbringen eines Barkodes mit der Adresse in kodierter Form. Für diese Offline-Videokodierung wird die Zeitspanne, in der schon die vollständig gelesenen Sendungen für dieses Verteilgebiet feinsortiert werden, zusätzlich genutzt. Damit können Videokodierplätze eingespart werden. Dieser Effekt ist am größten bei den zu kodierenden Sendungen für das lokale Verteilgebiet, da hier keine wesentliche Transportzeit (Transport der Sendungen zwischen den Verteilzentren) zum Videokodieren genutzt werden kann. Anschließend werden diese Sendungen ebenfalls zur Feinsortierung bereitgestellt 13.
If this address section could not be determined correctly 2, then the program receives an identification (ID tag) and it is sorted into a special sorting compartment (Refeed compartment) 3. These programs are then video-coded offline 4, if required Repeat loop. Thereafter, these shipments are pre-sorted in an additional run. In the sortable to the distribution areas broadcasts is then checked whether the address for the required sorting depth in fine sorting was read completely and uniquely and applied as a barcode 5.
If this is the case, then the programs are sorted into compartments as terminals for completely and uniquely read broadcasts of the determined distribution areas. 11. As soon as enough items have been sorted, they are taken from the sorting compartments (automatic or manual) and fed to fine sorting.
If the addresses have not been read completely, the next step is to check whether the items already have an ID tag. If so, they are sorted into compartments for incomplete (partially encoded) broadcasts of the identified distribution areas 12.
If an ID tag is not present, it will first be applied to the program 9. Subsequently, the offline coding is performed to completely read the address with the application of a bar code with the address in coded form. For this offline video coding, the time span in which the completely read programs are already sorted for this distribution area is additionally used. This can be used to save video encoding slots. This effect is greatest for the broadcasts to be encoded for the local distribution area, since no significant transport time (transport of broadcasts between the distribution centers) can be used for video coding. Subsequently, these items are also provided for fine sorting 13.

In der FIG 4 ist schematisch dargestellt, dass in einer Sortiereinrichtung 20 für jedes Verteilgebiet 1-n die Endstellen (Fächer) 21 in Endstellen für Sendungen mit vollständig gelesenen Adressen 21a und in Endstellen für Sendungen mit vollständig gelesenen Adressen 21b unterteilt sind.In the FIG. 4 It is shown schematically that in a sorting device 20 for each distribution area 1-n the terminals (compartments) 21 are divided into terminals for transmissions with fully read addresses 21a and in terminals for programs with fully read addresses 21b.

In den FIG 5a und 5b ist anschaulich das Prinzip des zusätzlichen Zeitgewinns für das Offline-Videokodieren der vollständigen Adresse dargestellt.In the FIG. 5a and 5b is clearly illustrated the principle of additional time savings for offline video coding of the full address.

FIG 5a zeigt den Zeitablauf bei der Vor- und Feinsortierung von lokalen Sendungen, d.h. von Sendungen aus dem Bereich des Verteil(Sortier)-Zentrums, deren Empfängeradressen ebenfalls in den Bereich dieses Verteil zentrums fallen. Die Vorsortierung wird auf 1 bis x Sortiereinrichtungen parallel durchgeführt, die anschließende Feinsortierung auf gleichen Sortiereinrichtungen nacheinander. FIG. 5a shows the timing in the pre-sorting and fine sorting of local broadcasts, ie broadcasts from the area of the distribution (sorting) center whose recipient addresses also fall within the range of this distribution center. The presorting is carried out in parallel on 1 to x sorting devices, the subsequent fine sorting on the same sorting devices in succession.

In FIG 5b ist der Zeitablauf bei paralleler Feinsortierung auf unterschiedlichen Sortiereinrichtungen dargestellt. Wie zu erkennen, ist hierbei der größte prozentuale Zeitgewinn zu verzeichnen.In FIG. 5b the time sequence for parallel fine sorting is shown on different sorting devices. As can be seen, this is the largest percentage of time saved.

Kommen noch getrennt übersandte, vollständig gelesene, fein zu sortierende Sendungen von anderen Verteilzentren hinzu, bei denen die Transportzeiten geringer als die Zeiten zum Feinsortieren der lokalen vollständig gelesenen Sendungen sind, so werden diese Sendungen auch noch vor den offline zu kodierende Sendungen feinsortiert. Dadurch vergrößert sich die zum Offline-Videokodieren zur Verfügung stehende Zeit nochmals.If separate, completely read, finely sorted consignments from other distribution centers are added separately, where the transport times are shorter than the times for fine sorting of the local fully read consignments, these consignments are also fine sorted before the programs to be coded offline. This increases the time available for offline video coding again.
