Stapelfach für flache SendungenStacking compartment for flat items
Die Erfindung betrifft ein Stapelfach für flache Sendungen, nach dem Oberbegriff des Anspruches 1.The invention relates to a stacking compartment for flat items, according to the preamble of claim 1.
Die Entleerung von Sortieranlagen für flache Sendungen mit entsprechenden Stapelfächern, in welche die Sendungen sor- tiert werden, erfolgt gegenwärtig noch häufig manuell, d.h. die sortierten Sendungsstapel werden von Hand aus der Sortieranlage in Postbehälter umgeladen. In die Stapelfächer werden die Sendungen jeweils mit einem Einstapelmechanismus geleitet .Sorting systems for flat mail items with corresponding stacking compartments into which the mail items are sorted are currently still emptied manually, i.e. The sorted batches of consignments are manually reloaded from the sorting system into mail containers. The consignments are each fed into the stacking compartments using a stacking mechanism.
Im Stapelfach ist eine linear geführte Stapelstütze angeordnet, die das Stapelende führt und ein Umkippen des Stapels verhindert. Zur manuellen Entleerung wird diese Stapelstütze nach oben aus dem Stapel rotativ herausgeschwenkt und weiter vorne nahe oder an der Einstapelstelle wieder in den Stapel abgesenkt. Hierbei hat sie sowohl eine stützende als auch eine trennende Funktion (Trennmesser) . Der somit abgetrennte Teil kann nun manuell aus dem Stapelfach entnommen werden. Hierbei können nur händisch handhabbare Mengen oder Stapel- längen entnommen und in Förderbehälter umgeladen werden. Je nach Fingerfertigkeit der Bedienkraft sind somit eine oder mehrere Zugriffe mit der damit verbundenen Bedienzeit für die Entleerung des Faches erforderlich.A linearly guided stack support is arranged in the stacking compartment, which guides the end of the stack and prevents the stack from tipping over. For manual emptying, this stack support is swiveled out of the stack in rotation and lowered further near the front or back into the stack at the stacking point. It has both a supporting and a separating function (cutting knife). The part thus separated can now be removed manually from the stacking compartment. Here only manually manageable quantities or stack lengths can be removed and reloaded into conveying containers. Depending on the dexterity of the operator, one or more accesses with the associated operating time are required to empty the compartment.
Moderne BriefSortieranlagen erreichen heute bereits durchschnittliche Spitzendurchsätze bis ca. 45.000 Sendungen pro Stunde (200 mm lange Sendungen) . Zukünftige High End Sorter werden noch höhere Durchsätze aufweisen. Eine Entleerung der Stapelfächer erfordert somit entweder bei manueller Bedienung mehr Bedienkräfte (unwirtschaftlich) oder im automatisierten Betrieb zusätzliche halb- oder vollautomatische Hilfsvorrichtungen für die Entleerung in die Transportbehälter. Teil- oder vollautomatisierte Systeme benötigen Anpassungen der auf die rein manuelle Entleerung ausgelegten Stapelfächer. Die bisher eingesetzten, nach oben schwenkbaren Stapel- stützen (Trennmesser) mit ihrer einfachen Geometrie haben den entscheidenden Nachteil, dass sie beim Herausschwenken der Stütze aufgrund der Reibung zwischen Stütze und Sendungsstapel Sendungen aus dem Stapel ziehen und somit zu Funktionsstörungen führen. Ein vollautomatisierter Prozess, der die gleiche Funktion nachvollzieht, ist somit stark stδrungsbe- haftet.Modern letter sorting systems already achieve average peak throughputs of up to around 45,000 items per hour (200 mm items). Future high end sorters will have even higher throughputs. Emptying the stacking compartments therefore requires more operating personnel (uneconomical) either with manual operation or additional semi or fully automatic auxiliary devices for emptying into the transport containers in automated operation. Partially or fully automated systems require adjustments to the stacking compartments designed for purely manual emptying. The previously used, upward swiveling stack supports (separating knife) with their simple geometry have the decisive disadvantage that when the support swings out, they pull items out of the stack due to the friction between the support and the stack of mail items and thus lead to malfunctions. A fully automated process that replicates the same function is therefore highly susceptible to malfunction.
In der JP 09-086 771 A wird ein Stapelfach für flache Sendungen beschrieben, dasJP 09-086 771 A describes a stacking compartment for flat mail items
- einen Stapelboden und eine dazu senkrechte Stapelwand, an der die Sendungen im Stapelfach anliegen,a stacking base and a stacking wall perpendicular thereto, on which the mail items lie in the stacking compartment,
- eine in annähernd horizontaler Stapelrichtung entlang der Stapelwand verschiebbare, den Stapel haltende Stapelstütze und- A stack support which can be moved in an approximately horizontal stacking direction along the stack wall and which holds the stack
- einen Schlitz im Stapelboden mit darin eingrei enden Vor- sprung der Stapelstütze aufweist .- Has a slot in the stack bottom with protruding protrusion of the stack support.
Weiterhin ist aus der GB-PS 1 303 135 für hochkant zu stapelnde flache Gegenstände eine Stapeleinrichtung bekannt, bei der die Stapelstütze nach unten in die Stapelbodenebene ver- senkbar ist.Furthermore, a stacking device is known from GB-PS 1 303 135 for flat objects to be stacked upright, in which the stacking support can be lowered down into the stacking floor level.
Beim Entleeren dieser Stapeleinrichtungen, auf eine nachfolgende Aufnahme durch Verschieben des Stapels, ist es nicht sichergestellt, dass dabei einzelne Sendungen am Ende der Stapeleinrichtungen nach unten durchrutschen.When emptying these stacking devices, to a subsequent pick-up by moving the stack, it is not ensured that individual consignments will slide down at the end of the stacking devices.
Der Erfindung liegt die Aufgabe zugrunde, ein Stapelfach mit einer Stapelstütze für Stapel von flachen Sendungen in stehender Position zu schaffen, bei dem während der Entleerung und der Verschiebung des Stapels keine Sendungen aus dem Stapelverbund entfernt werden. Erfindungsgemäß wird die Aufgabe durch ein Stapelfach mit den Merkmalen nach Anspruch 1 gelöst .The invention has for its object to provide a stacking tray with a stack support for stacks of flat mail items in a standing position, in which no mail items are removed from the stack assembly during emptying and moving the stack. According to the invention the object is achieved by a stacking compartment with the features of claim 1.
Die Stapelstütze ist am Ende des Stapelfaches nach unten in die Stapelbodenebene versenkbar ausgeführt . Der Stapelboden ist mindestens teilweise profiliert ausgeführt und die Stapelstütze mit ihrer im hochgefahrenen, den Stapel am Umfallen hindernden Zustand, auf dem Stapelboden gleitenden Fläche mit dem Bodenprofil kämmend ausgeführt. Dadurch wird keine Sen- düng nach oben mitgerissen, und dünne Sendungen können beim Verschieben infolge der Verzahnung nicht zwischen Stapelstütze und Stapelboden rutschen.At the end of the stacking compartment, the stacking support can be lowered into the stacking floor level. The stacking base is at least partially profiled and the stacking support is designed to mesh with the base profile with its surface sliding on the stacking base in the raised state, preventing the stack from falling over. As a result, no broadcast fertilizer is carried upwards, and thin consignments cannot slide between the stacking support and the stacking floor as a result of the interlocking.
Vorteilhafte Ausgestaltungen der Erfindung^ sind in den Unter- ansprüchen dargestellt.Advantageous embodiments of the invention ^ are shown in the dependent claims.
Das Versenken der Stapelstütze kann auf verschiedene vorteilhafte Art und Weise durchgeführt werden. So kann die Stapelstütze am Ende des Stapelfaches in Stapel- richtung nach unten in die Ebene des Stapelbodens schwenkbar ausgeführt werden. Die Stapelstütze übernimmt dann im heruntergeschwenkten Zustand die Funktion des Stapelbodens zur Überbrückung, damit der Stapel ohne Unterbrechung auf eine nachfolgende Auflagefläche geschoben werden kann. Dafür über- nimmt dann ein anderer Stützmechanismus, der von oben heruntergefahren wird, der aber nicht Erfindungsgegenstand ist, die Aufgabe der Stapelstütze.The stacking support can be sunk in various advantageous ways. In this way, the stacking support at the end of the stacking compartment can be pivoted downwards in the stacking direction into the level of the stacking base. The stack support then takes over the function of the stack base for bridging in the swung-down state, so that the stack can be pushed onto a subsequent support surface without interruption. For this purpose, another support mechanism, which is lowered from above, but which is not the subject of the invention, takes over the task of the stack support.
Vorteilhaft ist es auch, wenn die Stapelstütze am Ende des Stapelbodens vertikal verfahrbar ist und an ihrem oberen Rand einen im herunterge ahrenen Zustand annähernd parallel zum Stapelboden ausgerichteten Teil zum Überbrücken eines Spaltes zwischen dem Stapelboden und einer nachfolgenden Auflagefläche aufweist. Dabei ist auch der in Stapelrichtung befindli- ehe Abschlussrand des Stapelbodens profiliert ausgeführt und die dem profilierten Abschlussrand des Stapelbodens beim vertikalen Verfahren zugewandte Fläche der Stapelstütze so pro- filiert, dass sie beim Herunterfahren mit dem profilierten Rand des Stapelbodens kämmt. Durch diese kämmende Profilierung kann keine Sendung zwischen Stapelboden und Stapelstütze rutschen. Das vertikale Verfahren der Stapelstütze kann vorteilhaft durch ein Schwenken der Stapelstütze in der Ebene des Stapelbodens senkrecht zur Stapelrichtung realisiert werden. Um ein Wegrutschen der Sendungen von der Stapelwand zu verhindern, besitzt der Stapelboden vorteilhaft ein Sägezahnpro- fil, wobei die steilen Flanken zur Stapelwand gerichtet sind. Dadurch bleiben die Sendungen an den steilen Flanken hängen.It is also advantageous if the stacking support can be moved vertically at the end of the stacking base and, at its upper edge, has a part aligned in the lowered state approximately parallel to the stacking base for bridging a gap between the stacking base and a subsequent contact surface. The end edge of the stack base located in the stacking direction is also profiled and the surface of the stack support facing the profiled end edge of the stack base during vertical movement is filleted so that it combs with the profiled edge of the stacking floor when it is shut down. This intermeshing profiling means that no consignment can slip between the stacking floor and the stacking support. The vertical movement of the stack support can advantageously be realized by pivoting the stack support in the plane of the stack base perpendicular to the stack direction. In order to prevent the mail items from sliding away from the stacking wall, the stacking base advantageously has a sawtooth profile, the steep flanks being directed towards the stacking wall. As a result, the programs get stuck on the steep flanks.
Vorteilhaft ist es auch, wenn die Oberfläche des im heruntergefahrenen Zustand, annäherndeparallel„.zum Stapelboden ausge- richteten Teils der Stapelstütze das gleiche Oberflächenprofil wie der Stapelboden aufweist.It is also advantageous if the surface of the in the shutdown state is approximately e parallel “. part of the stacking support aligned with the stacking base has the same surface profile as the stacking base.
Anschließend wird die Erfindung in einem Ausführungsbeispiel anhand der Zeichnung näher erläutert .The invention is then explained in more detail in an exemplary embodiment with reference to the drawing.

Entsprechend FIG 1 werden die Sendungen 1 in aufrechter Position hintereinander in einem Deckbandsystem zwischen Trans- portriemen 2 eingeklemmt entlang nebeneinander liegender Stapelfächer 5 einer Sortiermaschine transportiert. Jedes Stapelfach 5 besteht aus einem Stapelboden 7 und einer dazu senkrechten Stapelwand 6. Vor jedem Stapelfach 5 befindet sich-eine--.Weic-henanordn_ung__mit _einem Weichenflügel _3 , um Sen- düngen entsprechend ihrer Zieladressen gezielt auszuschleusen. Mittels einer an sich bekannten Einstapeleinrichtung 4, auf die hier nicht näher eingegangen wird, werden die Sendungen 1 in das jeweilige Stapelfach 5 an eine Stapelstütze 8 oder an die letzte Sendung eines schon vorhandenen Stapels 11 geleitet. Dort werden sie an der Stapelwand 6 abgebremst und ausgerichtet. Die Stapelstütze 8 ist entlang der Stapelwand 6 gegen eine zur Einstapelstelle gerichtete Federkraft verschiebbar und in Stapelbodenebene schwenkbar geführt. Der Stapelboden 7 ist, wie in FIG 1 zu erkennen, in Sägezahn- form profiliert ausgeführt, wobei die Sägezahnflanken parallel zur Stapelwand 6 verlaufen und die steilen Flanken der Stapelwand 6 zugewandt sind. Die Stapelstütze 8 weist an ihrer auf dem Stapelboden 7 gleitenden Unterseite die gleiche Profilierung auf (FIG 4) , so dass beide Profile miteinander kämmen. Dadurch können keine dünnen und biegsamen Sendungen 1 zwischen Stapelboden 7 und Stapelstütze 8 rutschen und ein Zurückprallen oder -gleiten von der Stapelwand 6 wird weitgehend vermieden.According to FIG. 1, the mail items 1 are clamped in an upright position one behind the other in a shroud system between transport belts 2 and transported along stacking compartments 5 of a sorting machine. Each stacking compartment 5 consists of a stacking base 7 and a stacking wall 6 which is perpendicular thereto. In front of each stacking compartment 5 there is a switch arrangement with a switch wing 3 in order to specifically discharge the fertilizers according to their destination addresses. By means of a known stacking device 4, which will not be discussed in detail here, the mail items 1 are directed into the respective stacking compartment 5 to a stack support 8 or to the last mail item of an already existing stack 11. There they are braked and aligned on the stacking wall 6. The stack support 8 is displaceable along the stack wall 6 against a spring force directed towards the stacking point and is pivotably guided in the stack bottom plane. The stack base 7, as can be seen in FIG. 1, has a sawtooth shape, the sawtooth flanks running parallel to the stacking wall 6 and the steep flanks facing the stacking wall 6. The stack support 8 has the same profile on its underside sliding on the stack base 7 (FIG. 4), so that both profiles mesh with one another. As a result, no thin and flexible mailings 1 can slide between the stacking base 7 and the stacking support 8 and bouncing back or sliding off the stacking wall 6 is largely avoided.
Um genügend Platz für das Schwenkgelenk zu haben, hat die Stapelwand 6 in diesem unteren Bereich einen zurückgesetzten Teil. Beim Einstapeln erzeugt die entlang der Stapelwand 6 gerichtete Bewegungskomponente der Sendungen 1 eine Kraft, die die Stapelstütze 8 gegen die Federkraft von der Einstapelstelle weg verschiebt. Ist der Stapel 11 mit der Stapelstütze 8 am Ende des Stapelfaches 5 angelangt, entweder weil der Stapel 11 entsprechend groß ist oder weil der von der Einstapeleinrichtung 4 und der Stapelstütze 8 gehaltene Stapel 11 durch Bewegen der Einstapeleinrichtung 4 mit Hilfe einer mit dieser verbundenen Schubstange 10 entsprechend verschoben wurde, erfolgt das Herunterschwenken der Stapelstütze 8 entsprechend FIG 2 und 3, um den Stapel 11 auf eine nachfolgende Auflagefläche 12 schieben zu können. Damit die Sendungen 1 des Stapels 11 nicht in den Spalt zwischen Stapelboden 7 und Auflagefl che.12.j__alle.n, . be__sitzt_ d_ie_ Stapelstutz_e 8 an ihrem oberen Rand einen in der unteren Endstellung annähernd parallel zum Stapelboden 7 ausgerichteten Teil 9, der bei vollständig heruntergeschwenkter Stapelstütze 8 die Lücke überbrückt, die Auflagefläche 12 überlappend. Da auch zwischen Stapelboden 7 und Stapelstütze 8 dünne Sendungen 1 rutschen könnten, sind sowohl der in Stapelrichtung befindliche Abschlussrand 15 des Stapelbodens 8 als auch die dem Abschlussrand 15 beim Schwenken zugewandte Fläche 16 der Stapelstütze 8 so profiliert, dass sie miteinander kämmen. Das Profil ist ebenfalls sägezahnförmig ausgeführt, wobei das Profil an der Stapelstützenseite wegen der Schwenkbewegung kreisbogenförmig verläuft .In order to have enough space for the swivel joint, the stacking wall 6 has a recessed part in this lower area. During stacking, the movement component of the items 1 directed along the stacking wall 6 generates a force which pushes the stacking support 8 away from the stacking point against the spring force. Has the stack 11 with the stack support 8 reached the end of the stacking compartment 5, either because the stack 11 is correspondingly large or because the stack 11 held by the stacking device 4 and the stack support 8 by moving the stacking device 4 with the aid of a push rod 10 connected to it has been shifted accordingly, the stack support 8 is pivoted down according to FIGS. 2 and 3 in order to be able to push the stack 11 onto a subsequent support surface 12. So that the mail items 1 of the stack 11 do not che.12.j__alle.n, in the gap between the stack base 7 and Auflagefl. be__sitzt_ d_ie_ Stapelstutz_e 8 at its upper edge a part 9 oriented in the lower end position approximately parallel to the stacking base 7, which bridges the gap when the stacking support 8 is completely swung down, overlapping the bearing surface 12. Since thin consignments 1 could also slip between the stacking base 7 and the stacking support 8, both the end edge 15 of the stacking base 8 located in the stacking direction and the surface 16 of the stacking support 8 facing the end edge 15 during pivoting are profiled such that they mesh with one another. The profile is also sawtooth-shaped, the profile running on the stack support side because of the pivoting movement in a circular arc.
Die Sendungen 1 müssten also mit ihren Schmalseiten in diesem Sägezahnprofil verlaufen, um zwischen Stapelbodenrand und Stapelstütze 8 zu gelangen, was aufgrund ihrer Eigensteifig- keit nicht erfolgt. Bevor die Stapelstütze 8 am Ende des Stapelfaches 5 nach unten geschwenkt wird, wird ein nicht dargestellter externer Stützmechanismus neben die Stapelstütze 8 gefahren. Beim Nachuntenschwenken der Stapelstütze übernimmt der Stützmechanismus den Stapel 11 und fährt dann beim weite- ren Verfahren des Stapels 11 gesteuert weiter. Befinden sich alle Sendungen 1 des Stapels 11 auf der Auflagefläche 12, so werden durch die Ausnehmungen 13 Stützfinger 14 nach oben ge- fahren, die dann den Stapel 11 stützen, so dass die Einstapeleinrichtung 4 wieder in die Ausgangsstellung gebracht werden kann. The mailings 1 would therefore have to run with their narrow sides in this sawtooth profile in order to get between the edge of the stacking base and the stacking support 8, which does not take place due to their inherent rigidity. Before the stack support 8 is pivoted downward at the end of the stacking compartment 5, an external support mechanism (not shown) is moved next to the stack support 8. When the stack support is pivoted downwards, the support mechanism takes over the stack 11 and then continues to move in a controlled manner when the stack 11 is moved further. If all the mail items 1 of the stack 11 are on the support surface 12, the recesses 13 support fingers 14 upwards. drive, which then support the stack 11 so that the stacking device 4 can be brought back to the starting position.
