Description

Die auf Postsendungen, wie Briefen, Postkarten, Päckchen und dergleichen als Kennzahl für einen Ort, einen Zustellbereich, ein Postfach oder einen Großempfänger anzugebenden, maschinenlesbaren Postleitzahlen, ermöglichen eine rasche maschinelle Verteilung der Post. Das Sortieren der ankommenden Postsendungen erfolgt dabei mit Hilfe von steuerbaren Fördergutträgern, die in speziellen Eingabeplätzen manuell oder maschinell mit jeweils einer Postsendung beladen werden und diese Postsendung dann an einen der jeweiligen Postleitzahl zugeordneten Sortierbehälter oder ein entsprechendes Sortierfach abgeben. Da aus Gründen der Platzersparnis der Wunsch besteht, sowohl die Eingabeplätze, als auch die Sortierbehälter bzw. Sortierfächer in verschiedenen Ebenen anzuordnen, müssen die an Fördereinrichtungen umlaufenden Fördergutträger gegebenenfalls auch verschiedene Höhenlagen überbrücken können. Nach der Übergabe der Postsendung an den zugeordneten Sortierbehälter oder das zugeordnete Sortierfach, kann der leere Fördergutträger beim Passieren eines Eingabeplatzes erneut mit einer Postsendung beladen werden.The machine-readable postcodes to be specified on postal items, such as letters, postcards, parcels and the like, as a key figure for a location, a delivery area, a mailbox or a bulk recipient, enable the machine to be distributed quickly by machine. The incoming mail items are sorted with the aid of controllable conveying goods carriers, which are loaded manually or mechanically with one mail item each in special input locations and then deliver this mail item to a sorting container assigned to the respective postcode or a corresponding sorting compartment. Since, for reasons of space saving, there is a desire to arrange both the input places as well as the sorting containers or sorting compartments on different levels, the conveying goods carriers circulating at conveying devices may also have to be able to bridge different altitudes. After the mail item has been handed over to the assigned sorting container or the assigned sorting bin, the empty conveyed goods carrier can be loaded again with a mail item when it passes an input location.

Aus der US-A-3 300 026 ist eine Sortiereinrichtung für Postgut bekannt, die paarweise an einer Fördereinrichtung umlaufende Fördergutträger zur Aufnahme, zum Transport und zur steuerbaren Abgabe des Postguts an Sortierbehälter aufweist. Die Fördereinrichtung umfaßt zwei im Abstand zueinander endlos umlaufende Ketten, die über entsprechende Rollen mäanderförmig geführt sind, und die Fördergutträger in mehreren übereinanderliegenden Ebenen an jeweils einer Reihe mit Sortierbehältern entlangführen. Jeder der paarweise umlaufenden Fördergutträger umfaßt einen fest angeordneten Wandteil und einen beweglich angeordneten Wandteil, wobei der beweglich angeordnete Wandteil in einer Schließstellung zusammen mit dem fest angeordneten Wandteil eine im Querschnitt V-förmige Aufnahmetasche für das Postgut bildet, und wobei der beweglich angeordnete Wandteil in einer Abgabestellung zusammen mit dem fest angeordneten Wandteil einen nach unten offenen Austragsschlitz für das Fördergut bildet.From US-A-3 300 026 a sorting device for mail is known, which has pairs of rotating goods carriers on a conveyor for receiving, transporting and controllably delivering the mail to sorting containers. The conveying device comprises two endlessly revolving chains at a distance from one another, which are guided in a meandering manner via corresponding rollers and which guide the conveyed goods carriers along a row with sorting containers in several superimposed levels. Each of the conveying goods carriers rotating in pairs comprises a fixedly arranged wall part and a movably arranged wall part, the movably arranged wall part in a closed position together with the fixedly arranged wall part forms a V-shaped receiving pocket for the mail item in cross-section, and the movably arranged wall part forms a discharge slot for the conveyed goods, which is open at the bottom, in a delivery position together with the fixedly arranged wall part.

Der im Anspruch 1 angegebenen Erfindung liegt das Problem zugrunde, eine Sortiereinrichtung zu schaffen, die einfach aufgebaut ist und eine rasche und zuverlässige Übergabe des Förderguts an den zugeordneten Sortierbehälter oder das zugeordnete Sortierfach gewährleistet. Die Sortiereinrichtung soll dabei insbesondere auch für das Sortieren und Verteilen von dünnen Briefen geeignet sein.The invention specified in claim 1 is based on the problem of creating a sorting device which is of simple construction and ensures rapid and reliable transfer of the conveyed goods to the assigned sorting container or the assigned sorting compartment. The sorting device should also be particularly suitable for sorting and distributing thin letters.

Neben dem Sortieren und Verteilen von Postgut in öffentlichen Postämtern oder den Hauspostzentralen großer Firmen, kann eine erfindungsgemäße Sortiereinrichtung beispielsweise in Lagersystemen oder Kommissionierautomaten auch für vergleichbare Aufgaben eingesetzt werden, bei welchen mit Kodierungen versehene Waren oder Teile den jeweiligenen Kodierungen zugeordneten Sortierbehältern oder Sortierfächern zugeführt werden.In addition to sorting and distributing mail in public post offices or the in-house mail centers of large companies, a sorting device according to the invention can also be used, for example, in storage systems or automatic picking machines for comparable tasks in which goods or parts provided with codes are fed to the sorting containers or sorting compartments assigned to the respective codes.

Der Erfindung liegt die Erkenntnis zugrunde, daß aus einem fest angeordneten Wandteil und einem beweglich angeordneten Wandteil bestehende Fördergutträger in der Schließstellung auch Fördergut, wie z.B. dünne Briefe, zuverlässig aufnehmen können und in der Abgabe eine zuverlässig steuerbare Übergabe des Förderguts an einen zugeordneten Sortierbehälter oder ein zugeordnetes Sortierfach ermöglichen. Ein Anhalten oder Abbremsen der Fördergutträger bei der Übergabe des Förderguts ist dabei nicht erforderlich, da die sich an den Austragsschlitz anschließende und entgegen der Transportrichtung geneigte Austragsrutsche eine besonders sichere Ansteuerung des dem jeweiligen Fördergut zugeordneten Sortierbehälters oder Sortierfaches ermöglicht. Die Neigung der Austragsrutsche und die Geschwindigkeit des Fördergutträgers können dabei so aufeinander abgestimmt werden, daß sogar ein senkrechter Abwurf von dünnen Briefen erreichbar ist.The invention is based on the knowledge that, in the closed position, conveyed goods carriers consisting of a fixedly arranged wall part and a movably arranged wall part can also reliably take up conveyed goods, such as thin letters, and in the delivery a reliably controllable transfer of the conveyed goods to an assigned sorting container or a Allow assigned sort bin. It is not necessary to stop or slow down the conveyed goods carrier when transferring the conveyed goods, since the discharge chute that adjoins the discharge slot and is inclined against the transport direction ensures particularly reliable control of the Allows the sorting container or sorting compartment assigned to the respective conveyed good. The inclination of the discharge chute and the speed of the conveyed goods can be coordinated so that even a vertical drop of thin letters can be achieved.

Gemäß Anspruch 2 ist die Austragsrutsche dabei vorzugsweise durch den beweglichen Wandteil gebildet. Der Schwerpunkt des beweglichen Wandteils wird dabei nach unten verlagert, wodurch ein selbsttätiges Umschwenken von der Schließstellung in die Abgabestellung ohne zusätzliche Betätigungsmittel ermöglicht wird.According to claim 2, the discharge chute is preferably formed by the movable wall part. The center of gravity of the movable wall part is shifted downwards, which enables an automatic swiveling from the closed position into the delivery position without additional actuation means.

Die Ausgestaltung nach Anspruch 3 ermöglicht ein besonders einfaches Umschwenken des beweglichen Wandteils zwischen Schließstellung und Abgabestellung des Fördergutträgers.The embodiment according to claim 3 enables a particularly simple pivoting of the movable wall part between the closed position and the delivery position of the conveyed goods carrier.

Die Weiterbildung nach Anspruch 4 gewährleistet durch die gesicherte Schließstellung einen besonders sicheren Transport des Förderguts. Andererseits wird für die zuverlässige Einnahme der Abgabestellung nur ein Minimum an Aufwand benötigt.The development according to claim 4 ensures a particularly safe transport of the material to be conveyed through the secured closed position. On the other hand, only a minimum of effort is required to reliably take the delivery position.

Die Weiterbildung nach Anspruch 5 ermöglicht eine zuverlässige Aufnahme von verschiedenen Arten und Größen des Förderguts, wobei durch die Wölbungen gleichzeitig eine erhebliche Versteifung der Wandteile erreicht wird.The development according to claim 5 enables a reliable absorption of different types and sizes of the material to be conveyed, with the bulges at the same time achieving considerable stiffening of the wall parts.

Die Ausgestaltung nach Anspruch 65 gewährleistet einen besonders sicheren Transport des Förderguts, da die ineinandergreifende Verzahnung auch im Falle einer nicht vollständigen Schließstellung ein Herausfallen dünner Briefe oder dergleichen verhindert.The embodiment according to claim 65 ensures a particularly safe transport of the conveyed material, since the interlocking toothing also in the case of incomplete one Closed position prevents thin letters or the like from falling out.

Die Ausgestaltung nach Anspruch 7 ermöglicht eine weitere Versteifung der Wandteile, wobei die wellenförmige Ausgestaltung gleichzeitig auch ein unerwünschtes Anhaften von dünnen Briefen oder dergleichen an den Wandteilen des Fördergutträgers verhindert.The embodiment according to claim 7 enables a further stiffening of the wall parts, the wave-shaped configuration at the same time also preventing undesired adhesion of thin letters or the like to the wall parts of the conveyed goods carrier.

Die Ausgestaltung nach Anspruch 8 ermöglicht eine seitlich auskragende Anordnung der Fördergutträger an einem umlaufenden Transportwagen, wobei die Fördergutträger auch zwischen zwei mit relativ geringem vertikalen Abstand zueinander angeordneten Reihen von Sortierbehältern hindurchgeführt werden können. An den Transportwagen sind dabei gemäß Anspruch 9 vorzugsweise zwei oder mehrere Fördergutträger befestigt, wodurch sich eine weitere Reduzierung des baulichen Aufwands für die gesamte Fördereinrichtung ergibt.The embodiment according to claim 8 enables a laterally projecting arrangement of the conveyed goods carriers on a rotating transport carriage, the conveyed goods carriers also being able to be passed between two rows of sorting containers arranged at a relatively small vertical distance from one another. According to claim 9, two or more conveyed goods carriers are preferably fastened to the transport carriage, which results in a further reduction in the structural outlay for the entire conveying device.

Die Weiterbildung nach Anspruch 10 ermöglicht eine seitliche Beladung der Fördergutträger, wodurch besonders geringe Bauhöhen der Sortiereinrichtung realisiert werden können.The development according to claim 10 enables a lateral loading of the conveyed goods carrier, whereby particularly low overall heights of the sorting device can be realized.

Die Ausgestaltung nach Anspruch 11 ermöglicht mit einem minimalen baulichen Aufwand eine sichere Führung der Transportwagen, wobei die Profile gemäß Anspruch 12 vorzugsweise rohrförmig ausgebildet sind.The embodiment according to claim 11 enables safe guiding of the transport trolleys with minimal construction effort, the profiles according to claim 12 preferably being tubular.

Die Weiterbildung nach Anspruch 13 ermöglicht eine robuste und zuverlässige Anordnung der beiden Profile in den geradlinig verlaufenden Abschnitten der Fördereinrichtung, so daß in den Kurven- und Umlenkungsbereichen der Fördereinrichtung auf zusätzliche Befestigungsmittel für die Profile verzichtet werden kann.The development according to claim 13 enables a robust and reliable arrangement of the two profiles in the rectilinear sections of the conveyor, so that additional fastening means for the profiles can be dispensed with in the curve and deflection regions of the conveyor.

Die Ausgestaltung nach Anspruch 14 ermöglicht mit besonders geringem Aufwand einen zuverlässigen und robusten Antrieb der Transportwagen.The embodiment according to claim 14 enables a reliable and robust drive of the trolley with particularly little effort.

Die Weiterbildung nach Anspruch 15 ermöglicht bei gleicher Aufstellungsfläche der gesamten Sortiereinrichtung beispielsweise eine Verdoppelung der für die Sortieraufgaben zur Verfügung stehenden Sortierbehälter. Der Transportwagen wird dabei gemäß Anspruch 16 in jeder Ebene an jeweils zwei parallelen Reihen mit Sortierbehältern entlang geführt. Die hierzu erforderlichen U-förmigen Umlenkungen und höhengängigen Umlenkungen sind dabei durch die Rollenführung der Transportwagen auf zwei Profilen und durch den Antrieb mit einem umlaufenden Transportseil besonders einfach realisierbar.The development according to claim 15 makes it possible, for example, for the same sorting area of the entire sorting device to double the sorting containers available for the sorting tasks. The transport carriage is guided along two parallel rows with sorting containers in each plane. The required U-shaped deflections and height-adjustable deflections are particularly easy to achieve by the roller guide of the transport trolley on two profiles and by the drive with a rotating transport cable.

Figur 1 zeigt in perspektivischer Darstellung einen insgesamt mit FT bezeichneten Fördergutträger, der einen fest angeordneten Wandteil FW und einen beweglichen Wandteil BW umfaßt. Der bewegliche Wandteil BW ist dabei um eine quer zur Transportrichtung TR des Fördergutträgers FT ausgerichtete Drehachse DA schwenkbar.Figure 1 shows a perspective view of a generally designated FT conveyor, which comprises a fixed wall part FW and a movable wall part BW. The movable wall part BW can be pivoted about an axis of rotation DA oriented transversely to the transport direction TR of the conveyed goods carrier FT.

Figur 1 zeigt die Schließstellung des Fördergutträgers FT, in welcher der fest angeordnete Wandteil FW und der beweglich angeordnete Wandteil BW, die beide jeweils nach außen gewölbt sind, eine im Querschnitt etwa V-förmige Aufnahmetasche für das Fördergut bilden Gemäß Figur 2 sind die beiden Wandteile FW und BW jeweils wellenförmig gebogen, wobei in der in einer Draufsicht von oben dargestellten Schhließstellung SS beide Wandteile FW und BW mit einer Verzahnung VZ ineinandergreifen. Die Sicherung der Schließstellung SS erfolgt gemaß Figur 1 durch eine Sperrklinke SK, die um eine mit A bezeichnete Achse drehbar und durch Betätigung eines Hubmagneten HM lösbar ist. Wird die Sperrklinke SK gelöst, so wird der bewegliche Wandteil BW um die Drehachse DA derart verschwenkt, daß sich ein nach unten offener Austragsschlitz des Fördergutträgers FT bildet. Die untere Verlängerung des beweglich angeordneten Wandteils BW bildet dabei eine sich nach unten an diesen Austragsschlitz anschließende Austragsrutsche AR, die entgegen der Transportrichtung TR geneigt ist.Figure 1 shows the closed position of the conveyed goods carrier FT, in which the fixed wall part FW and the movably arranged wall part BW, both of which are curved outwards, form an approximately V-shaped receiving pocket for the conveyed goods in cross section. According to FIG. 2, the two wall parts are FW and BW are each curved in a wave shape, with the two wall parts FW and BW intermeshing with a toothing VZ in the closed position SS shown in a plan view from above. The locking position SS is secured according to FIG. 1 by means of a pawl SK which can be rotated about an axis labeled A and can be released by actuating a lifting magnet HM. If the pawl SK is released, the movable wall part BW is pivoted about the axis of rotation DA in such a way that a discharge slot of the conveyed goods carrier FT which is open at the bottom is formed. The lower extension of the movably arranged wall part BW forms a discharge chute AR which adjoins this discharge slot and which is inclined against the transport direction TR.

Figur 3 zeigt eine perspektivische Darstellung von zwei aneinandergereihten Modulen M1 und M2 einer mit Fördergutträgern FT gemäß Figur 1 ausgerüsteten Sortiereinrichtung. Dabei sind jeweils insgesamt fünf Fördergutträger FT an einem Transportwagen TW angebracht, der Bestandteil einer Fördereinrichtung FE ist und in zwei Ebenen E1 und E2 umläuft. Jedes Modul M1 und M2 besitzt in jeder Ebene E1 und E2 jeweils zwei Auflagebleche AB, auf welchen Sortierbehälter SB dicht aneinandergereiht aufgestellt werden können. Es ist zu erkennen, daß die Fördergutträger FT an den Transportwagen TW derart über den Sortierbehältern SB umlaufen, daß bei Betätigung der Sperrklinke SK (vergleiche Figur 1) das in Figur 3 nicht näher dargestellte Fördergut in einen der jeweiligen Kodierung zugeordneten Sortierbehälter SB abgeworfen werden kann.FIG. 3 shows a perspective view of two modules M1 and M2 of a sorting device equipped with conveyed goods carriers FT according to FIG. 1. In each case, a total of five conveyed goods carriers FT are attached to a transport carriage TW, which is part of a conveying device FE and rotates in two levels E1 and E2. Each module M1 and M2 has two support plates AB in each level E1 and E2, on which sorting containers SB can be placed close to one another. It can be seen that the conveyed goods carriers FT circulate on the transport trolleys TW above the sorting containers SB in such a way that when the pawl SK is actuated (see FIG. 1) the material to be conveyed (not shown in more detail in FIG. 3) can be thrown into a sorting container SB assigned to the respective coding.

In dem hier dargestellten Querschnitt ist zu erkennen, daß der Transportwagen TW über mit R bezeichnete Rollen auf zwei sich in Transportrichtung TR (vergleiche Figur 1) erstreckenden, rohrförmigen Profilen P geführt ist. Die im vertikalen Abstand parallel zueinander ausgerichteten Profile P sind dabei in geradlinig verlaufenden Bereichen der Fördereinrichtung FE über sich ebenfalls in Transportrichtung TR erstreckende Stege ST miteinander verbunden, während in den Kurvenbereichen auf diese Stege ST verzichtet wird. Der Antrieb eines Transportwagens TW erfolgt über ein endlos umlaufenden Transportseil TS, an welchem der Transportwagen TW mit Hilfe eines Mitnehmers MN befestigt ist. Auf der dem Transportseil TS gegenüberliegenden Seite besitzt der Transportwagen TW ein Tragblech TB, an welchem die einzelnen Fördergutträger FT stirnseitig befestigt werden und welches auch die Sperrklinken SK und die zugeordneten Hubmagnete HM trägt. Das Tragblech TB fungiert dabei als Halterung für die Drehachsen DA der beweglichen Wandteile BW, während die festen Wandteile FW der einzelnen Fördergutträger FT über stirnseitige Flansche F (vergleiche Figur 1) fest mit dem Tragblech TB verbunden werden.FIG. 4 shows further details of the conveying device FE shown in FIG. 3. In the cross section shown here it can be seen that the transport carriage TW is guided by rollers denoted by R on two tubular profiles P which extend in the transport direction TR (compare FIG. 1). The profiles P, which are aligned parallel to one another at a vertical spacing, are connected to one another in rectilinear regions of the conveying device FE via webs ST which also extend in the transport direction TR, while these webs ST are dispensed with in the curved regions. A transport trolley TW is driven by an endlessly rotating transport cable TS, to which the transport trolley TW is fastened with the aid of a driver MN. On the side opposite the transport cable TS, the transport trolley TW has a support plate TB to which the individual conveyed goods carriers FT are fastened on the end face and which also carries the pawls SK and the associated lifting magnets HM. The support plate TB acts as a holder for the axes of rotation DA of the movable wall parts BW, while the fixed wall parts FW of the individual conveyed goods carriers FT are firmly connected to the support plate TB via end flanges F (see FIG. 1).

Figur 5 zeigt eine Studie über den zeitunabhängigen Bewegungsablauf beim Abwurf des Förderguts aus den erfindungsgemäßen Fördergutträgern FT. Auf der linken Seite der hier gezeigten Darstellung ist ein Fördergutträger FT in seiner Schließstellung SS zu erkennen. Bei dem gestrichelt dargestellten Fördergut FG soll es sich hier um einen dünnen Brief handeln.FIG. 5 shows a study of the time-independent movement sequence when the conveyed goods are ejected from the conveyed goods carriers FT according to the invention. On the left side of the illustration shown here, a conveyed goods carrier FT can be seen in its closed position SS. The conveyed goods FG shown in dashed lines should be a thin letter.

Der von links gesehen zweite Fördergutträger FT ist bereits in seiner Abgabestellung AS dargestellt, in welcher der bewegliche Wandteil BW durch eine Drehung um die Drehachse DA zusammen mit dem fest angeordneten Wandteil FW einen Austragsschlitz für das Fördergut FG bildet. Aus den nachfolgenden Stellungen des Förderguts FG ist zu erkennen, daß dieses über die Austragsrutsche AR nach unten gleitet und dabei neben der nach unten gerichteten senkrechten Bewegungskomponente eine der Transportrichtung TR entgegengesetzte horizontale Bewegungskomponente erhält. Dabei können die Transportgeschwindigkeit in Transportrichtung TR und die Neigung der Austragsrutsche AR so aufeinander abgestimmt werden, daß das Fördergut FG zumindest weitgehend senkrecht nach unten in einen zugeordneten Sortierbehälter SB (vergleiche Figur 3) fallen kann.The second conveyed goods carrier FT seen from the left is already shown in its delivery position AS, in which the movable wall part BW forms a discharge slot for the conveyed goods FG by rotating about the axis of rotation DA together with the fixedly arranged wall part FW. From the following positions of the material to be conveyed FG it can be seen that it slides down over the discharge chute AR and, in addition to the vertical movement component directed downwards, receives a horizontal movement component opposite to the transport direction TR. The transport speed in the transport direction TR and the inclination of the discharge chute AR can be coordinated with one another in such a way that the conveyed goods FG can at least largely fall vertically downwards into an assigned sorting container SB (cf. FIG. 3).

Die Figuren 6 und 7 zeigen eine aus einzelnen Modulen M zusammengesetzte Sortiereinrichtung in der Seitenansicht bzw. in der Draufsicht. Die einzelnen Module M entsprechen dabei den in Figur 3 dargestellten Modulen M1 und M2, wobei in Figur 6 jedoch noch ein zusätzliches, unterhalb der unteren Ebene E1 angeordnetes Zuführband ZB für die Bereitstellung leerer Sortierbehälter SB dargestellt ist. Bei der Entnahme eines vollen Sortierbehälters SB aus der Ebene E1 oder der Ebene E2 kann dann dieser durch einen auf dem Zuführband ZB bereitgestellten leeren Sortierbehälter SB ersetzt werden.FIGS. 6 and 7 show a sorting device composed of individual modules M in side view and in top view. The individual modules M correspond the modules M1 and M2 shown in FIG. 3, but in FIG. 6 there is also an additional feed belt ZB arranged below the lower level E1 for the provision of empty sorting containers SB. When a full sorting container SB is removed from level E1 or level E2, it can then be replaced by an empty sorting container SB provided on the feed belt ZB.

Bei der Darstellung gemäß den Figuren 6 und 7 befindet sich auf der linken Seite vor dem ersten Modul M eine höhengängige Umlenkung HU, während sich auf der rechten Seite an das letzte Modul M ein stirnseitiges Eingabemodul EM anschließt. Es ist zu erkennen, daß im Bereich dieses Eingabemoduls EM die einzelnen Fördergutträger FT von der Rückseite, von der Stirnseite, oder von der Vorderseite her beladen werden können, wobei die Beladung manuell oder maschinell vorgenommen werden kann.In the illustration according to FIGS. 6 and 7, there is a vertical deflection HU on the left-hand side in front of the first module M, while an end-side input module EM is connected to the last module M on the right-hand side. It can be seen that in the area of this input module EM the individual conveyed goods carriers FT can be loaded from the rear, from the front, or from the front, the loading being able to be carried out manually or by machine.

Figur 8 zeigt in stark vereinfachter schematischer Darstellung die Führung der Fördereinrichtung FE (vergleiche Figuren 3 und 4) über die beiden Ebenen E1 und E2. Die Linie L zeigt dabei den räumlichen Verlauf des Transportseils TS (vergleiche Figur 4), wobei die Transportrichtung durch Pfeile TR aufgezeigt ist. Die Führung des Transportseils TS im Bereich der höhengängigen Umlenkung HU und im Bereich des Eingabemoduls EM ist dabei durch Umlenkrollen U angedeutet. Der entsprechende, parallel zur Linie L geführte räumliche Verlauf der Profile P (vergleiche Figur 4) ist in Figur 3 nicht erkennbar.FIG. 8 shows in a highly simplified schematic representation the guidance of the conveying device FE (compare FIGS. 3 and 4) over the two levels E1 and E2. Line L shows the spatial course of the transport rope TS (see FIG. 4), the direction of transport being indicated by arrows TR. The guidance of the transport rope TS in the area of the vertical deflection HU and in the area of the input module EM is indicated by pulleys U. The corresponding spatial profile of the profiles P (see FIG. 4), which runs parallel to the line L, cannot be seen in FIG.

Die beispielsweise in einer rückwärtigen Beladezone der unteren Ebene E1 (vergleiche Figur 7) mit Fördergut FG beladen Fördergutträger FT, werden im stirnseitigen Bereich des Eingabemoduls EM auf gleicher Höhe nach vorne umgelenkt und dann an den auf der Vorderseite auf dem unteren Ablageblech AB angeordneten Sortierbehältern SB vorbeitransportiert. Im Bereich der höhengängigen Umlenkung HU werden die Fördergutträger FT dann schräg nach oben in die obere Ebene E2 geführt und dort an den auf der Rückseite auf dem oberen Ablageblech AB angeordneten Sortierbehältern SB vorbeitransportiert. Im Bereich des Eingabemoduls EM werden die Fördergutträger FT dann auf gleicher Höhe nach vorne umgelenkt und dann an den auf der Vorderseite auf dem oberen Ablageblech angeordneten Sortierbehältern SB vorbeitransportiert. Im Bereich der höhengängigen Umlenkung HU werden die Fördergutträger FT dann schräg nach unten in die untere Ebene E1 geführt und dort an den auf der Rückseite auf dem unteren Ablageblech AB angeordneten Sortierbehältern SB vorbeitransportiert. Auf dem vorstehend beschriebenen Transportweg geben die einzelnen Fördergutträger FT das mitgeführte Fördergut FG an einen zugeordneten Sortierbehälter SB ab, so daß sie dann beim Passieren der rückseitigen Beladezone erneut mit Förderugt FG beladen werden können.For example, in a rear loading zone of the lower level E1 (compare FIG. 7) loaded with conveyed goods FG, conveyed goods carriers FT are deflected forward at the same height in the front area of the input module EM and then to the sorting containers SB arranged on the front on the lower storage plate AB transported past. In the area of the vertical deflection HU, the conveyed goods carriers FT are then guided diagonally upwards into the upper level E2 and transported there past the sorting containers SB arranged on the rear on the upper storage tray AB. In the area of the input module EM, the conveyed goods carriers FT are then deflected forward at the same height and then transported past the sorting containers SB arranged on the front on the upper storage tray. In the area of the vertical deflection HU, the conveyed goods carriers FT are then guided obliquely downwards into the lower level E1 and transported there past the sorting containers SB arranged on the rear on the lower storage tray AB. On the transport route described above, the individual conveyed goods carriers FT deliver the carried conveyed goods FG to an assigned sorting container SB, so that they can then be loaded again with conveying conveyor FG when they pass the rear loading zone.
