- lateral detection of the position of the sorted item can be more reliable than detecting from above and / or below, especially in the case of vertical sorting of narrow sorted items such as letters.
- the position of the sorting material can also be determined with a detection device designed as a light barrier.
- the sorting system can additionally comprise a control unit which is designed to associate the specific position of the sorted item with a sorting compartment.
- control device can be configured to check whether the sorting compartment assigned on the basis of the determined position of the sorted item agrees with the sorting compartment assigned to the destination information. So can be determined based on the position of the sorted goods, whether the sorted material has been classified in the correct bin.

- FIG. 1 shows according to one embodiment of the invention, a sorting system 14 for letters 2b, which is also useful for other flat sorting goods 2.
- the sorting system is shown by the sorting page 8.
- Each letter 2b is marked with a delivery address 6a representing a destination information 6.
- the sorting system 14 comprises a sorting register 4 with sorting compartments F 11 - F 59 arranged in rows and columns into which the letters 6 b are sorted by an operator.
- Each sorting bin F ij is assigned a set of determination information 6 - for example, a set of locally adjacent delivery addresses 6b is sorted into a common sorting bin F ij .
- Letters 2b which form horizontal sorting stock stacks 2s, have already been sorted into all sorting compartments F ij provided with a reference numeral in the drawing.
- An operator detects the postal 6a and assigns a letterskysortierenden 2b a specific sorting compartment F to 22, wherein this process can be mechanically supported. Subsequently, the letter 2b is sorted by the Einsortierseite 8 in the sorting compartment F 22 .
- a detection device 10 is arranged, wherein the detection device 10 comprises a number of columns of the sorting register 4 corresponding number of detection segments 18 1 - 18 9 .
- the detection device 10 is currently being sorted by the operator of the Einsortierseite 8 forth in the bin F 22 configured to contactless detect the position of the letter 2b.
- the detection device 4 on the Einsortierseite 8 slightly protrude above the sorting register 4 in order to capture the letter 2b from above can.
- the detection segments 18 i measure the distance d i between their respective reference point 12 i and the just sorted letter 2 b. Anand the measured distance d i , the height of the letter 2b and thus the sorting line can be determined based on the detecting detection segment 18 i the sorting column.
- the distance d i between letter and reference point 12 i is greater than a minimum distance 12 i, min and less than a maximum distance 12 i, max .
- Each detection segment 18 i thus covers a column of sorting compartments F ij - in the case of a lateral arrangement of the detection apparatus 4, one row would be correspondingly covered.
- the assignment of measured Distance d i or position of the letter 2 b to a sorting compartment F ij is carried out by a control device 22 associated with the detection device 10, which thus detects in which amount the letter 2b is pushed into the sorting compartment F ij .
- the distance d i is determined by the detection device 10 or its detection segments 18 i emit electromagnetic radiation, wherein the emitted light beam 20 is interrupted by the letter 2 b.
- the accuracy of the distance determination is thus dependent on the measurement accuracy of the detection device 10 which is determined by the wavelength used, beam focusing and the sensitivity of the detection device 10.
- Particularly suitable for the distance measurement are lasers because a laser beam can be bundled and aligned particularly well.
- FIG. 2 shows a further sorting system 14 in a side view according to another embodiment of the invention. Shown is a detection segment 18 3 and a control device 22 of the detection device 10. Shown is the temporally not simultaneously occurring sorting three flat sorted goods 2, 2 ', 2 "from the Einsortierseite 8.
- the reference point 12 3 is above and laterally immediately before the sorting compartments F i3 on the sorting side 8, so that the measured distance d 1 lies directly in front of the sorting compartment F 13 within the minimum distance d 1, min and d 1, max even if the sorting goods 2 are in an inclined position
- the sorting register 4 makes it possible to protect sensitive components of the detection device 10 particularly easily against dust and other contamination, for example through a cover, since the components for light beam generation and detection are oriented downwards differently dimensioned sorted goods 2 is unproblematic with central arrangement of the detection segment 18 i or their reference points 12 i , as long as the sorting goods 2 are at least half as wide as a sorting compartment F ij , because in narrower sorting goods 2 may not be sorted sorting a sorted material not be recorded.
- FIG. 3 shows another sorting system 14 according to yet another embodiment of the invention.
- the detection segments 18 1 - 18 9 produce a light cone 20 ', so that the coverage area is increased, but for the price of reduced accuracy.
- FIG. 4 shows a sorting system 14 with a beam deflection according to another embodiment of the invention.
- the detection device 10, 10 ' is arranged above and below the sorting register 4, wherein the lower detection device 10' obliquely to each other and at an angle to the light beam 10 arranged reflectors, which increase the coverage area.
- All detection devices 10, 10 'of FIGS. 1 to 5 are designed as distance measuring devices that generate and detect electromagnetic radiation in order to determine the sorting compartment F ij on the basis of the measured distance d i between a reference point 12 i and the sorted item 2 and thus on the basis of the position of the sorted item 2 during sorting, into which the sorted item 2 sorted.
- FIG. 5 shows according to an embodiment of the invention, a sorting system 14 with a detection device 10 ', 10 "with orthogonal components to each other.
- the detection device 10' is above the sorting register 4th
- this embodiment is only suitable for wider sorting goods 2, that is to say, for example, parcels, parcels or other piece goods, since narrow sorting goods 2, such as letters 2b, are recognized by a light barrier only from one direction.
- the detection range of a light barrier is in this case a row or a column, so that the number of required detection segments 18 corresponds to the number of rows plus the number of columns of the sorting compartments F ij .
- the operator just sorts the sorted material 2 into the sorting compartment F 33 , so that both the detection segment 18 3 "and the detection segment 18 3 'indicate an occupancy .. Based on this information, the control unit 22 can read that the unit load 2 is in the sorting compartment F 33 is sorted.
- the control device 22 comprises a processor board, with which the detected signal, in particular the acquired data of individual detection segments 18, are interrogated one after the other. From this, the sorting compartment F ij , into which the sorted item 2 was sorted, can be determined and compared with the sorting compartment F ij originally associated with the determination information 6.
- the detection devices 10 can be easily mounted on existing sorting compartments F ij and only require some space above and / or to the side and / or below the sorting register 4. A required wiring can be arranged above or on the back of the sorting register.
- the controller 22 can be easily connected to existing sorting systems.
- the controller 22 checks whether the with the associated information based on the determination of the 6 Sortierguts 2 bin F ij matches based on the determined position of the Sortierguts 2 associated bin F ij. If the check shows no match, an optical and / or audible warning is issued by the controller 22. After issuing this warning, the faulty sorted item 2 can be taken out of the sorting bin F ij and a new sorting attempt can be made
- the course of the position of the sorting material 2 is detected during sorting, so as to better enable a unique assignment. If a sorted 2 is not completely inserted and is still in the light beam 20, then this can be displayed.
- the sorting system 14 includes a detection means for acquiring the determination information 6 of the sorted material 2 and for assigning a sorting compartment F ij, and also a display means for displaying the sorting compartment F ij associated with the determination information 6 of the sorted material 2.
- a designed as a distance measuring device detection device 10 may include a laser.
- the distance can be detected on the basis of transit time measurement and / or phase position measurement and / or laser triangulation of the emitted light beam 20.

Description
Die vorliegende Erfindung betrifft ein Sortiersystem und ein Verfahren zur Verfolgung eines Einsortierens eines Sortierguts in ein Sortierregister.The present invention relates to a sorting system and a method for tracking a sorting of a sorted product into a sorting register.
Sortiergüter werden häufig am Ende einer Kette von Sortier-vorgängen nach ihrer Bestimmungsinformation manuell in ein Sortierregister, auch Sortierrack genannt, einsortiert. Das Sortierregister umfasst Sortierfächer, die jeweils einem Satz von Bestimmungsinformationen zugeordnet sind. Jedes Sortiergut wird manuell anhand seiner Bestimmungsinformation in das zugeordnete Sortierfach einsortiert. Die Sortiergüter können Versandstücke und Postsendungen wie Briefe aber auch kommissionierbare Stückgüter oder andere Waren sein. Bei der vollständig manuellen Einsortierung wird die Bestimmungsinformation von einem menschlichen Bediener ausgelesen und in das der Bestimmungsinformation entsprechende Sortierfach abgelegt. Im nächsten Automatisierungsschritt wird die Bestimmungsinformation automatisch erfasst und dem Bediener das Sortierfach, in das das Sortiergut abgelegt werden soll, angezeigt. Damit muss der Bediener die Zuordnung von Bestimmungsinformation und Sortierfach nicht mehr auswendig kennen.Sorted goods are often sorted manually at the end of a chain of sorting operations according to their destination information in a sorting register, also called sorting track. The sort register includes sort bins each associated with a set of destination information. Each item to be sorted is manually sorted by its destination information in the associated bin. The sorted goods can be packages and postal items such as letters, but also commissionable general cargo or other goods. In the case of completely manual sorting, the destination information is read out by a human operator and stored in the sorting bin corresponding to the destination information. In the next automation step, the determination information is automatically recorded and the operator the sorting tray, in which the sorting material is to be stored, displayed. This means that the operator no longer has to know the assignment of the determination information and the sorting compartment by heart.
In der Briefsortierung erfolgt ein Einsortieren der Briefe und anderer flacher Postsendungen in das Sortierregister so, dass ein Zusteller die Postsendungen in der Gangfolge seines Zustellweges für die Auslieferung bereitstellen kann. Die Bestimmungsinformation eines Briefes ist seine Zustelladresse.In the letter sorting, the letters and other flat mail items are sorted into the sorting register in such a way that a deliverer can provide the mailpieces in the order of their delivery route for delivery. The destination information of a letter is its delivery address.
Hierzu sind beispielsweise aus der internationalen Patentanmeldung
Die oben genannten Hilfsmittel helfen zwar, Sortierfehler zu verringern und beschleunigen das Einsortieren, überwachen jedoch nicht den Vorgang des Einsortierens selber, so dass ein fehlerhaftes Einsortieren nicht mehr korrigiert wird.Although the above tools help reduce sorting errors and speed up sorting, they do not monitor the sorting process itself, so incorrect sorting is no longer corrected.
Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, ein Verfahren und ein Sortiersystem zur Verfolgung eines Einsortierens eines Sortierguts in ein Sortierregister. Diese Aufgabe wird durch die in den unabhängigen Ansprüchen beschriebenen Lösungen gelöst.The present invention is therefore based on the object, a method and a sorting system for tracking a Einsortierens sorted into a sorting register. This object is achieved by the solutions described in the independent claims.
Die erfindungsgemäße Lösung sieht ein Verfahren zur Verfolgung eines Einsortierens eines mit einer Bestimmungsinformation, insbesondere einer Zustelladresse, versehenen Sortierguts in ein Sortierregister eines Sortiersystems vor. Das Verfahren umfasst die folgenden Verfahrensschritte:
- a) Bereitstellen des Sortierregisters mit einer Anzahl von Sortierfächern;
- b) Zuordnen von einem Satz von Bestimmungsinformationen zu den Sortierfächern;
- c) Erfassen der Bestimmungsinformation von dem Sortiergut und Ermitteln des dieser Bestimmungsinformation zugeordneten Sortierfachs;
- d) Einsortieren des Sortierguts in das der Bestimmungsinformation zugeordnete Sortierfach;
- e) Bestimmen einer Position des Sortierguts auf der Einsortierseite des Sortierregisters während des Einsortierens des Sortierguts mit Hilfe einer Detektionsvorrichtung zum berührungslosen Erfassen einer Position des Sortierguts auf einer Einsortierseite des Sortierregisters; und
- f) Zuordnen dieser Position zu einem Sortierfach.
- a) providing the sort register with a number of bins;
- b) assigning a set of destination information to the bins;
- c) detecting the destination information from the sorted goods and determining the sorting compartment associated with this destination information;
- d) sorting the sorted goods into the sorting compartment assigned to the destination information;
- e) determining a position of the sorted item on the sorting side of the sorting register during the sorting of the sorted item by means of a detection device for the non-contact detection of a position of the sorted item on a sorting page of the sorting register; and
- f) Assign this item to a bin.
Gemäß einer Ausführungsform kann die Detektionsvorrichtung während des Einsortierens einen Abstand zwischen einem durch die Detektionsvorrichtung vorgegebenen Referenzpunkt und dem Sortiergut messen um die Position des Sortierguts zu bestimmen. Anhand des Abstands kann bei bekannter Position der Sortierfächer relativ zum Referenzpunkt besonders einfach die Position bestimmt werden.According to one embodiment, during sorting, the detection device can measure a distance between a reference point predetermined by the detection device and the sorted item in order to determine the position of the sorted item. Based on the distance, the position can be determined in a known position of the sorting compartments relative to the reference point particularly simple.
Um die Position des Sortierguts berührungslos und mit geringem Ausleseaufwand zu ermitteln, kann die Detektionsvorrichtung die Position des Sortierguts erfassen, indem sie elektromagnetische Strahlung erzeugt und detektiert.In order to determine the position of the sorting material without contact and with low readout effort, the detection device can detect the position of the sorting material by generating and detecting electromagnetic radiation.
Gemäß einer weiteren Ausführungsform kann die Detektionsvorrichtung oberhalb und/ oder unterhalb der Sortierfächer auf der Einsortierseite des Sortierregisters angeordnet sein. Besonders einfach können so horizontal bzw. liegend in die Sortierfächer einzuordnende Sortiergüter erfasst werden. Durch die Anordnung auf der Einsortierseite können die Sortiergüter während des Einsortierens verfolgt werden. Bei Anordnung oberhalb des Sortierregisters befindet sich die Detektionsvorrichtung nicht im Einsortierbereich und stellt somit kein allzu großes Hindernis mit Kollisionsgefahr dar und benötigt nur etwas Platz oberhalb des Sortierregisters. Eine baugleiche Detektionsvorrichtung kann prinzipiell auch unterhalb der Sortierfächer angeordnet werden. Eine gleichzeitige Anordnung von Komponenten der Detektionsvorrichtung ermöglicht eine Verbreiterung des abgedeckten Messbereichs, beispielsweise durch Strahlumlenkung.According to a further embodiment, the detection device can be arranged above and / or below the sorting compartments on the sorting side of the sorting register. It is particularly easy to record sorting goods to be sorted horizontally or horizontally into the sorting compartments. The arrangement on the Einsortierseite the sorted goods can be tracked during sorting. When arranged above the sorting register, the detection device is not in Einsortierbereich and thus does not constitute a very large obstacle with risk of collision and only needs some space above the sorting register. A structurally identical detection device can in principle also below the Sorting compartments are arranged. A simultaneous arrangement of components of the detection device allows broadening of the covered measuring range, for example by beam deflection.
Um ein Bestimmen der Position des Sortierguts von noch mehr Referenzpunkten aus zu ermöglichen, kann die Detektionsvorrichtung auf einer ersten Seite und/ oder auf einer zweiten Seite der Sortierfächer auf der Einsortierseite des Sortierregisters angeordnet ist. Bei einer gleichzeitigen Anordnung der Detektionsvorrichtung bzw. ihrer Komponenten von zwei nicht parallel zueinander angeordneten Seiten - also an einer ersten Seite und oben - kann auch ohne Abstandsmessung sondern nur anhand einer Feststellung einer Anwesenheit des Sortierguts die Position des Sortierguts ermittelt werden.In order to make it possible to determine the position of the sorted item from even more reference points, the detection apparatus can be arranged on a first side and / or on a second side of the sorting compartments on the sorting side of the sorting register. In a simultaneous arrangement of the detection device or its components of two non-parallel sides - ie on a first side and top - can also be determined by measuring the presence of the sorting goods, the position of the sorting material without distance measurement.
Gemäß einer weiteren Ausführungsform kann ein Verlauf der Position des Sortierguts beim Einsortieren erfasst werden. So können zusätzliche Datenpunkte verwendet werden um ein eindeutiges und noch robusteres Zuordnen zu einem Sortierfach zu erlauben. Fehlerhafte Positionsbestimmungen bei der anstelle der Position des Sortierguts eine Position von Störkonturen, beispielsweise den Händen eines Bedieners, erfasst werden, können so leichter erkannt werden.According to a further embodiment, a course of the position of the sorted goods can be detected during sorting. Thus, additional data points can be used to allow a clear and even more robust assignment to a bin. Faulty position determinations in which a position of interfering contours, for example the hands of an operator, are detected instead of the position of the sorted goods, can thus be detected more easily.
Um ein erfolgtes fehlerhaftes Einsortieren zu erkennen, kann überprüft werden, ob das anhand der bestimmten Position des Sortierguts zugeordnete Sortierfach mit dem der Bestimmungsinformation zugeordneten Sortierfach übereinstimmt. Bei mangelnder Übereinstimmung kann eine Warnung ausgegeben werden und das Sortiergut erneut einsortiert werden.In order to detect a faulty sorting carried out, it can be checked whether the sorting compartment assigned on the basis of the determined position of the sorted item agrees with the sorting compartment assigned to the destination information. If there is a mismatch, a warning can be issued and the sorted goods can be sorted again.
Hinsichtlich einer Vorrichtung wird die vorstehend genannte Aufgabe gelöst durch Sortiersystem für ein mit einer Bestimmungsinformation, insbesondere einer Zustelladresse, versehenes Sortiergut, umfassend ein Sortierregister umfassend eine Anzahl von Sortierfächern zur Aufnahme des Sortierguts, wobei den Sortierfächern jeweils ein Satz von Bestimmungsinformationen zuordenbar ist und jedes Sortiergut anhand seiner Bestimmungsinformation in ein Sortierfach einsortierbar ist. Das Sortiersystem umfasst zudem eine Detektionsvorrichtung, die ausgestaltet ist zum berührungslosen Bestimmen einer Position des Sortierguts auf einer Einsortierseite des Sortierregisters während eines Einsortierens des Sortierguts.With regard to a device, the above-mentioned object is achieved by sorting system for one with a destination information, in particular a delivery address, provided Sortiergut, comprising a sorting register comprising a number of sorting compartments for receiving the sorting goods, wherein the sorting compartments each a set of determination information is assigned and each sorted material is sortable by its determination information in a sorting bin. The sorting system further comprises a detection device which is designed for contactless determination of a position of the sorted item on a sorting side of the sorting register during sorting of the sorted item.
Gemäß einer Ausführungsform kann die Detektionsvorrichtung als Abstandsmessvorrichtung ausgestaltet sein, um während des Einsortierens einen Abstand zwischen einem durch die Detektionsvorrichtung vorgegebenen Referenzpunkt und dem Sortiergut zu messen. Anhand des gemessenen Abstands kann besonders einfach - ohne komplizierte Auswertung - die Position des Sortierguts bestimmt werden.According to one embodiment, the detection device may be configured as a distance measuring device in order to measure a distance between a reference point predetermined by the detection device and the sorted material during sorting. Based on the measured distance, the position of the material to be sorted can be determined particularly simply - without complicated evaluation.
Die Detektionsvorrichtung kann zum Erzeugen und/ oder Detektieren elektromagnetischer Strahlung ausgestaltet sein um die Position des Sortierguts zu bestimmen. So kann die Detektionsvorrichtung berührungslos und einfach auswertbar die Position des Sortierguts bestimmen.The detection device can be designed to generate and / or detect electromagnetic radiation in order to determine the position of the sorting material. Thus, the detection device contactless and easily evaluable determine the position of the sorted.
Um mit möglichst wenig Aufwand das Einsortieren des Sortierguts in sämtliche Sortierfächer zu überwachen, kann die Detektionsvorrichtung auf der Einsortierseite ober- und/ oder unterhalb des Sortierregisters angeordnet sein.In order to monitor the sorting of the sorted goods into all sorting compartments with as little effort as possible, the detection device can be arranged on the sorting side above and / or below the sorting register.
Um die Position des Sortierguts auch seitlich zu erfassen, kann die Detektionsvorrichtung auf der Einsortierseite auf einer ersten Seite und/ oder auf einer zweiten Seite des Sortierregisters angeordnet sein. Bei einem vertikalen Einsortieren kann ein seitliches Erfassen der Position des Sortierguts zuverlässiger sein als ein Erfassen von oben und/ oder unten, insbesondere bei einem vertikalen Einsortieren schmaler Sortiergüter wie Briefen. Kombiniert mit einer horizontalen Anordnung von oben und/ oder unten kann auch mit einer als Lichtschranke ausgestalteten Detektionsvorrichtung die Position des Sortierguts bestimmt werden.In order to laterally detect the position of the sorting material, the detection device can be arranged on the sorting side on a first side and / or on a second side of the sorting register. For a vertical sorting For example, lateral detection of the position of the sorted item can be more reliable than detecting from above and / or below, especially in the case of vertical sorting of narrow sorted items such as letters. Combined with a horizontal arrangement from above and / or below, the position of the sorting material can also be determined with a detection device designed as a light barrier.
Um das Sortierfach zu ermitteln, in das das Sortiergut einsortiert wird, kann das Sortiersystem zudem eine Steuereinrichtung umfassen, die ausgestaltet ist, die bestimmte Position des Sortierguts einem Sortierfach zuzuordnen.In order to determine the sorting compartment into which the sorted item is sorted, the sorting system can additionally comprise a control unit which is designed to associate the specific position of the sorted item with a sorting compartment.
Gemäß einer weiteren Ausführungsform kann die Steuereinrichtung ausgestaltet sein zu überprüfen, ob das anhand der bestimmten Position des Sortierguts zugeordnete Sortierfach mit dem der Bestimmungsinformation zugeordneten Sortierfach übereinstimmt. So kann anhand der Position des Sortierguts festgestellt werden, ob das Sortiergut in das richtige Sortierfach eingeordnet worden ist.According to a further embodiment, the control device can be configured to check whether the sorting compartment assigned on the basis of the determined position of the sorted item agrees with the sorting compartment assigned to the destination information. So can be determined based on the position of the sorted goods, whether the sorted material has been classified in the correct bin.
Gemäß einer weiteren Ausführungsform kann die Detektionsvorrichtung eine mit einer Anzahl an Spalten und/ oder Zeilen des Sortierregisters übereinstimmende Anzahl an Detektionssegmenten umfassen. So kann mit sehr geringem Aufwand zum Bestimmen der Position das erfasste Signal eines Detektionssegment einer bestimmten Spalte bzw. Zeile zugeordnet werden. Eine segmentierte Bauweise erlaubt ein einfaches Anpassen der Ausmaße der Detektionsvorrichtung an die Maße des Sortierregisters, indem die Detektionsvorrichtung aus der entsprechende Anzahl an Detektionssegmenten ausgebildet wird.According to a further embodiment, the detection device may comprise a number of detection segments corresponding to a number of columns and / or rows of the sorting register. Thus, with very little effort for determining the position, the detected signal of a detection segment can be assigned to a specific column or row. A segmented design allows a simple adaptation of the dimensions of the detection device to the dimensions of the sorting register by the detection device is formed from the corresponding number of detection segments.

Ein Bediener erfasst die Zustelladresse 6a und ordnet einen einzusortierenden Brief 2b einem bestimmten Sortierfach F22 zu, wobei dieser Vorgang maschinell unterstützt werden kann. Anschließend wird der Brief 2b von der Einsortierseite 8 in das Sortierfach F22 einsortiert. Oberhalb und entlang der gesamten Breite des Sortierregisters 4 ist eine Detektionsvorrichtung 10 angeordnet, wobei die Detektionsvorrichtung 10 eine der Anzahl der Spalten des Sortierregisters 4 entsprechende Anzahl an Detektionssegmenten 181 - 189 umfasst. Die Detektionsvorrichtung 10 ist ausgestaltet berührungslos die Position des Briefs 2b zu erkennen, der gerade vom Bediener von der Einsortierseite 8 her in das Sortierfach F22 einsortiert wird. Hierzu muss die Detektionsvorrichtung 4 auf der Einsortierseite 8 leicht über das Sortierregister 4 hinausragen, um den Brief 2b von oben her erfassen zu können.An operator detects the postal 6a and assigns a
Bei einem Einsortieren mit horizontalem Ablegen der Briefe 2b wie in
Die Detektionssegmente 18i messen den Abstand di zwischen ihrem jeweiligen Referenzpunkt 12i und dem gerade einsortierten Brief 2b. Anand des gemessenen Abstands di kann die Höhe des Briefs 2b und somit die Sortierfachzeile ermittelt werden, anhand des erfassenden Detektionssegments 18i die Sortierfachspalte. Wenn ein Brief 2b in ein Fach Fij einsortiert wird, ist der Abstand di zwischen Brief und Referenzpunkt 12i größer als ein minimaler Abstand 12i,min und kleiner als ein maximaler Abstand 12i,max. Jedes Detektionssegment 18i deckt also eine Spalte von Sortierfächern Fij ab - bei einer seitlichen Anordnung der Detektionsvorrichtung 4 würde entsprechend eine Zeile abgedeckt werden. Die Zuordnung von gemessenem Abstand di bzw. Position des Briefs 2b zu einem Sortierfach Fij wird von einer mit der Detektionsvorrichtung 10 assoziierten Steuereinrichtung 22 ausgeführt, die somit erkennt, in welcher Höhe der Brief 2b in das Sortierfach Fij geschoben wird.The
Der Abstand di wird ermittelt, indem die Detektionsvorrichtung 10 bzw. ihre Detektionssegmente 18i elektromagnetische Strahlung aussenden, wobei der ausgesandte Lichtstrahl 20 durch den Brief 2b unterbrochen wird. Die Genauigkeit der Abstandsermittlung ist somit abhängig von der Messgenauigkeit der Detektionsvorrichtung 10 die durch die verwendete Wellenlänge, Strahlbündelung und die Empfindlichkeit der Detektionsvorrichtung 10 bestimmt wird. Für die Abstandsmessung besonders geeignet sind Laser da sich ein Laserstrahl besonders gut bündeln und ausrichten lässt.The distance d i is determined by the

Je nach Ausführungsform werden die von den Detektionsvorrichtungen 10 erfassten Daten digital oder analog ausgelesen. Die Steuereinrichtung 22 umfasst hierzu ein Prozessorboard, mit dem das erfasste Signal, insbesondere die erfassten Daten einzelner Detektionssegmente 18, nacheinander abgefragt werden. Daraus lässt sich das Sortierfach Fij, in das das Sortiergut 2 einsortiert wurde ermitteln und mit dem ursprünglich anhand der Bestimmungsinformation 6 zugeordneten Sortierfach Fij abgleichen. Die Detektionsvorrichtungen 10 können leicht an bereits existierende Sortierfächer Fij angebaut werden und erfordern lediglich etwas Platz oberhalb und/ oder seitlich und/ oder unterhalb des Sortierregisters 4. Eine erforderliche Verkabelung kann oberhalb oder auf der Rückseite des Sortierregisters angeordnet werden. Die Steuereinrichtung 22 kann leicht mit bestehenden Sortiersystemen verbunden werden. Dies ist erforderlich, da sonst die Steuereinrichtung 22 nicht wissen kann, welches das ursprünglich anhand der Bestimmungsinformation 6 zugeordnete Sortierfach Fij ist. Die Steuereinrichtung 22 überprüft, ob das anhand der bestimmten Position des Sortierguts 2 zugeordnete Sortierfach Fij mit dem anhand der Bestimmungsinformation 6 des Sortierguts 2 zugeordneten Sortierfach Fij übereinstimmt. Wenn die Überprüfung keine Übereinstimmung zeigt, wird eine optische und/ oder akustische Warnung von der Steuereinrichtung 22 ausgegeben. Nach Ausgabe dieser Warnung kann das fehlerhafte Sortiergut 2 aus dem Sortierfach Fij herausgenommen werden und es kann ein erneuter Einsortierversuch unternommen werdenDepending on the embodiment, the data acquired by the
Gemäß einer weiteren Ausführungsform wird der Verlauf der Position des Sortierguts 2 beim Einsortieren erfasst, um so noch besser ein eindeutiges Zuordnen zu ermöglichen. Wird ein Sortiergut 2 nicht ganz eingeschoben und liegt noch im Lichtstrahl 20, dann kann dies angezeigt werden. Das Sortiersystem 14 umfasst ein Erfassungsmittel zum Erfassen der Bestimmungsinformation 6 des Sortierguts 2 und zum Zuordnen eines Sortierfachs Fij und zudem ein Anzeigemittel zum Anzeigen des der Bestimmungsinformation 6 des Sortierguts 2 zugeordneten Sortierfachs Fij.According to a further embodiment, the course of the position of the sorting
