Definitions
- the machine-readable postcodes to be specified on postal items, such as letters, postcards, parcels and the like, as an identification number 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 a mail item in special input places 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 and 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 transferred to the assigned sorting container or the assigned sorting compartment, the empty conveyed goods container can be loaded with a mail item again when it passes an input location.
- a sorting device for mail is known from FR-A-24 54 338, which has a plurality of conveying goods carriers rotating around a conveying device for receiving, transporting and controllably delivering the mail.
- the conveyed goods carriers are fastened in pairs opposite to each other on rotating transport nacelles of the conveyor, the transport nacelles, for example driven by an endless chain, being guided with rollers on a vertically oriented rail that extends in the transport direction.
- the transport gondolas are guided in the area of two adjacent, U-shaped deflections of the conveying device along a total of four parallel double rows with sorting containers into which the mail item from the conveyed item carriers can be dropped.
- a circulation of the transport gondolas hanging on the rails in two or more levels would be difficult to implement due to the large construction height of the hanging gondolas.
- a sorting device for mail is known from US-A-3 300 026, which has pairs of conveying goods carriers rotating in pairs on a conveying device for receiving, transporting and controllably delivering the mail.
- the conveying device comprises two chains which run endlessly at a distance from one another and which are guided in a meandering manner via corresponding rollers and guide the conveyed goods carriers along a row with sorting containers on several superimposed levels.
- the meandering course of the conveyor in several levels results in a relatively large overall height of the sorting device with a correspondingly poor accessibility of the sorting containers arranged in the upper levels.
- the invention specified in claim 1 is based on the problem of creating a sorting device, the transport device of which is of simple construction and enables reliable transport of the conveyed goods carriers between the input location and the sorting containers or sorting compartments assigned to the respective conveyed goods.
- the transport device should in particular be able to bridge different altitudes with little effort.
- a sorting device 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.
- the transport trolleys form simple and robust means of transport for the conveyed goods carriers, the guidance and the drive of the transport trolleys being able to be realized with a minimal construction effort via two profiles extending in the transport direction and an endlessly rotating transport cable .
- the circulation of the transport trolleys in at least two levels enables, for example, a doubling of the sorting containers available for the sorting tasks with the same installation area of the entire sorting device.
- the trolley is guided along two parallel rows of sorting bins on each level.
- the U-shaped deflections and height-adjustable deflections required for this are particularly easy to achieve by the roller guide of the transport carriage on two profiles and by the drive with endlessly rotating transport means.
- the development according to claim 3 enables a lateral loading of the conveyed goods carrier, whereby particularly small heights of the sorting device can be realized.
- the costs of materials for the conveyor can be further reduced while reducing the weight.
- the embodiment according to claim 6 enables a reliable and low-noise drive of the trolley with little effort.
- 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.
- FIG. 1 shows the closed position of the conveyed goods carrier FT, in which the fixedly arranged 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.
- the two wall parts FW and BW are each curved in a wave-like manner, wherein in the closed position SS shown in a top view, both wall parts FW and BW engage with a toothing VZ.
- the locking position SS is secured according to FIG. 1 by a locking link SK which can be rotated about an axis labeled A and can be released by actuating a lifting magnet HM.
- 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 counter to the transport direction TR.
- 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.
- 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 on the transport car TW rotate over the sorting containers SB in such a way that when the pawl SK (see FIG. 1) is actuated, the conveyed goods not shown in FIG. 3 can be dropped into a sorting container SB assigned to the respective coding .
- FIG. 4 shows further details of the conveying device FE shown in FIG. 3.
- 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 omitted 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.
- the transport trolley TW 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).
- 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.
- 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.
- 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. It can be seen from the following positions of the conveyed material FG that it slides downward over the discharge chute AR and, in addition to the downward vertical movement component, 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 are coordinated with one another in such a way that the conveyed goods FG can at least largely fall vertically downward into an assigned sorting container SB (see FIG. 3).
- 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 to the modules M1 and M2 shown in FIG. 3, but in FIG. 6 there is also shown an additional feed belt ZB arranged below the lower level E1 for the provision of empty sorting containers SB.
- an additional feed belt ZB arranged below the lower level E1 for the provision of empty sorting containers SB.
- 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.
- 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 deflecting rollers U.
- the corresponding spatial profile of the profiles P (see FIG. 4), which runs parallel to the line L, cannot be seen in FIG.
- the conveyed goods carriers FT loaded with conveyed goods FG 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 support plate AB transported past.
- the conveyed goods carriers FT are then guided obliquely upwards into the upper level E2 and transported there past the sorting containers SB arranged on the rear on the upper support plate AB.
- 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 support plate AB.
- the conveyed goods carriers FT are then inclined downwards into the lower level E1 guided and transported past the sorting containers SB arranged on the rear on the lower support plate AB.
- 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 conveyed goods FG when they pass the rear loading zone.

Abstract
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 Fördergutbehälter 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 an identification number 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 a mail item in special input places 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 and 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 transferred to the assigned sorting container or the assigned sorting compartment, the empty conveyed goods container can be loaded with a mail item again when it passes an input location.
Aus der FR-A-24 54 338 ist eine Sortiereinrichtung für Postgut bekannt, die mehrere an einer Fördereinrichtung umlaufende Fördergutträger zur Aufnahme, zum Transport und zur steuerbaren Abgabe des Postguts aufweist. Die Fördergutträger sind dabei paarweise einander gegenüberliegend an umlaufenden Transportgondeln der Fördereinrichtung befestigt, wobei die beispielsweise durch eine endlose Kette angetriebenen Transportgondeln mit Rollen auf einer vertikal ausgerichteten und sich in Transportrichtung erstreckenden Schiene geführt sind. Die Transportgondeln sind im Bereich von Zwei nebeneinanderliegenden, U-förmigen Umlenkungen der Fördereinrichtung an insgesamt vier parallelen Doppelreihen mit Sortierbehältern entlanggeführt, in welche das Postgut aus den Fördergutträgern abgeworfen werden kann. Ein Umlauf der an den Schienen hängenden Transportgondeln in zwei oder mehreren Ebenen wäre durch die große Bauhöhe der hängenden Gondeln nur schwer realisierbar.A sorting device for mail is known from FR-A-24 54 338, which has a plurality of conveying goods carriers rotating around a conveying device for receiving, transporting and controllably delivering the mail. The conveyed goods carriers are fastened in pairs opposite to each other on rotating transport nacelles of the conveyor, the transport nacelles, for example driven by an endless chain, being guided with rollers on a vertically oriented rail that extends in the transport direction. The transport gondolas are guided in the area of two adjacent, U-shaped deflections of the conveying device along a total of four parallel double rows with sorting containers into which the mail item from the conveyed item carriers can be dropped. A circulation of the transport gondolas hanging on the rails in two or more levels would be difficult to implement due to the large construction height of the hanging gondolas.
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 aufweist. Die Fördereinrichtung umfaßt zwei im Abstand zueinander endlos umlaufende Ketten, die über entsprechende Rollen mäanderförmig geführt sind und die Fördergutträger an mehreren übereinanderliegenden Ebenen an jeweils einer Reihe mit Sortierbehältern entlangführen. Durch den mäanderförmigen Verlauf der Fördereinrichtung in mehreren Ebenen ergibt sich eine relativ große Bauhöhe der Sortiereinrichtung mit einer entsprechend schlechten Zugänglichkeit der in den oberen Ebenen angeordneten Sortierbehälter.A sorting device for mail is known from US-A-3 300 026, which has pairs of conveying goods carriers rotating in pairs on a conveying device for receiving, transporting and controllably delivering the mail. The conveying device comprises two chains which run endlessly at a distance from one another and which are guided in a meandering manner via corresponding rollers and guide the conveyed goods carriers along a row with sorting containers on several superimposed levels. The meandering course of the conveyor in several levels results in a relatively large overall height of the sorting device with a correspondingly poor accessibility of the sorting containers arranged in the upper levels.
Der im Anspruch 1 angegebenen Erfindung liegt das Problem zugrunde, eine Sortiereinrichtung zu schaffen, deren Transporteinrichtung einfach aufgebaut ist und einen zuverlässigen Transport der Fördergutträger zwischen dem Eingabeplatz und den dem jeweiligen Fördergut zugeordneten Sortierbehältern oder Sortierfächern ermöglicht. Die Transporteinrichtung soll dabei insbesondere auch mit geringem Aufwand verschiedene Höhenlagen überbrücken können.The invention specified in claim 1 is based on the problem of creating a sorting device, the transport device of which is of simple construction and enables reliable transport of the conveyed goods carriers between the input location and the sorting containers or sorting compartments assigned to the respective conveyed goods. The transport device should in particular be able to bridge different altitudes with little effort.
Neben dem Sortieren und Verteilen von Postgut in öffentlichen Postämern 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 jeweiligen 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.
Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß die Transportwagen einfache und robuste Transportmittel für die Fördergutträger bilden, wobei die Führung und der Antrieb der Transportwagen über zwei sich in Transportrichtung erstreckende Profile und ein endlos umlaufendes Transportseil mit einem minimalen baulichen Aufwand realisiert werden können. Der Umlauf der Transportwagen in mindestens zwei Ebenen ermöglicht bei gleicher Aufstellungsfläche der gesamten Sortiereinrichtung beispielsweise eine Verdoppelung der für die Sortieraufgaben zur Verfügung stehenden Sortierbehälter. Der Transportwagen wird dabei in jeder Ebene an jeweils zwei parallelen Reihen mit Sortierbehältern entlanggeführt. Die hierzu erforderlichen U-förmigen Umlenkungen und höhengängigen Umlenkungen sind dabei durch die Rollenführung der Transportwagen auf zwei Profilen und durch den Antrieb mit endlos umlaufenden Transportmitteln besonders einfach realisierbar.The advantages achieved by the invention are, in particular, that the transport trolleys form simple and robust means of transport for the conveyed goods carriers, the guidance and the drive of the transport trolleys being able to be realized with a minimal construction effort via two profiles extending in the transport direction and an endlessly rotating transport cable . The circulation of the transport trolleys in at least two levels enables, for example, a doubling of the sorting containers available for the sorting tasks with the same installation area of the entire sorting device. The trolley is guided along two parallel rows of sorting bins on each level. The U-shaped deflections and height-adjustable deflections required for this are particularly easy to achieve by the roller guide of the transport carriage on two profiles and by the drive with endlessly rotating transport means.
Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben.Advantageous embodiments of the invention are specified in the subclaims.
Sind an einem Transportwagen gemäß Anspruch 2 mindestens zwei Fördergutträger befestigt, so ergibt sich hierdurch eine weitere Reduzierung des baulichen Aufwands für die gesamte Fördereinrichtung.If at least two conveyed goods carriers are fastened to a transport carriage, this results in a further reduction in the structural outlay for the entire conveying device.
Die Weiterbildung nach Anspruch 3 ermöglicht eine seitliche Beladung der Fördergutträger, wodurch besonders geringe Bauhöhen der Sortiereinrichtung realisiert werden können.The development according to claim 3 enables a lateral loading of the conveyed goods carrier, whereby particularly small heights of the sorting device can be realized.
Sind die Profile gemäß Anspruch 4 rohrförmig ausgebildet, so kann der Materialaufwand für die Fördereinrichtung bei gleichzeitiger Reduzierung des Gewichts weiter verringert werden.If the profiles are tubular, the cost of materials for the conveyor can be further reduced while reducing the weight.
Die Weiterbildung nach Anspruch 5 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 5 enables a robust and reliable arrangement of the two profiles in the straight extending 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 6 ermöglicht mit geringem Aufwand einen zuverlässigen und geräuscharmen Antrieb der Transportwagen.The embodiment according to claim 6 enables a reliable and low-noise drive of the trolley with little effort.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben.An embodiment of the invention is shown in the drawing and will be described in more detail below.

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 Draufsieht von oben dargestellten Schließstellung SS beide Wandteile FW und BW mit einer Verzahnung VZ ineinandergreifen. Die Sicherung der Schließstellung SS erfolgt gemäß Figur 1 durch eine Sperrlinke 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.FIG. 1 shows the closed position of the conveyed goods carrier FT, in which the fixedly arranged 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. According to FIG. 2, the two wall parts FW and BW are each curved in a wave-like manner, wherein in the closed position SS shown in a top view, both wall parts FW and BW engage with a toothing VZ. The locking position SS is secured according to FIG. 1 by a locking link 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 counter to 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. Here 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 on the transport car TW rotate over the sorting containers SB in such a way that when the pawl SK (see FIG. 1) is actuated, the conveyed goods not shown in FIG. 3 can be dropped into a sorting container SB assigned to the respective coding .
Figur 4 zeigt nähere Einzelheiten der in Figur 3 dargestellten Fördereinrichtung FE. 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 omitted 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. It can be seen from the following positions of the conveyed material FG that it slides downward over the discharge chute AR and, in addition to the downward vertical movement component, 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 are coordinated with one another in such a way that the conveyed goods FG can at least largely fall vertically downward into an assigned sorting container SB (see 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 to the modules M1 and M2 shown in FIG. 3, but in FIG. 6 there is also shown 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 deflecting rollers 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 6) mit Fördergut FG beladenen 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 Auflageblech 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 Auflageblech 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 Auflageblech AB 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 Auflageblech 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 Fördergut FG beladen werden können.For example, in a rear loading zone of the lower level E1 (see FIG. 6), the conveyed goods carriers FT loaded with conveyed goods FG 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 support plate AB transported past. In the area of the vertical deflection HU, the conveyed goods carriers FT are then guided obliquely upwards into the upper level E2 and transported there past the sorting containers SB arranged on the rear on the upper support plate 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 support plate AB. In the area of the vertical deflection HU, the conveyed goods carriers FT are then inclined downwards into the lower level E1 guided and transported past the sorting containers SB arranged on the rear on the lower support plate 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 conveyed goods FG when they pass the rear loading zone.
