Description

Die Erfindung betrifft ein Stapelfach für flache Sendungen, nach dem Oberbegriff des Anspruches 1.The invention relates to a stacking tray for flat items, according to the preamble of claim 1.

Die Entleerung von Sortieranlagen für flache Sendungen mit entsprechenden Stapelfächern, in welche die Sendungen sortiert 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.The emptying of flat-stock sorting machines with corresponding stacking compartments into which the mailings are sorted is still frequently done manually, i.e., at a high level. the sorted consignment stacks are manually transferred from the sorting system to postal containers. The consignments are each fed with a stacking mechanism into the stacking compartments.

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 Stapellängen 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.In the stacker a linearly guided stack support is arranged, which leads the stack end and prevents tipping of the stack. For manual emptying, this stacking support is pivoted upwards out of the stack and further lowered near the front or at the stacking point back into the stack. Here it has both a supporting and a separating function (cutting knife). The thus separated part can now be removed manually from the stacker. Here, only manually manageable quantities or staple lengths can be removed and reloaded into delivery containers. Depending on the dexterity of the operator thus one or more accesses with the associated service time for the emptying of the compartment are required.

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.Today, modern letter sorting systems already achieve average peak throughputs of up to 45,000 items per hour (200 mm long items). Future high-end sorters will have even higher throughputs. An emptying of the stacking compartments thus requires more manual or manual operation (uneconomical) or additional automatic semi-automatic or fully automatic auxiliary devices for emptying into the transport container.

Teil- oder vollautomatisierte Systeme benötigen Anpassungen der auf die rein manuelle Entleerung ausgelegten Stapelfächer. Die bisher eingesetzten, nach oben schwenkbaren Stapelstützen (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 störungsbehaftet.Partially or fully automated systems require adaptations of the stacking compartments designed for purely manual emptying. The previously used, upwardly pivotable stacking supports (separating knife) with their simple geometry have the distinct disadvantage that they pull out of the stack when swinging out of the support due to the friction between the support and stack of items and thus lead to malfunction. A fully automated process that retraces the same function is thus heavily disrupted.

In der JP 09-086 771 A wird ein Stapelfach für flache Sendungen beschrieben, das

  • einen Stapelboden und eine dazu senkrechte Stapelwand, an der die Sendungen im Stapelfach anliegen,
  • eine in annähernd horizontaler Stapelrichtung entlang der Stapelwand verschiebbare, den Stapel haltende Stapelstütze und
  • einen Schlitz im Stapelboden mit darin eingreifenden Vorsprung der Stapelstütze
aufweist.In JP 09-086 771 A a stacking tray is described for flat broadcasts, the
  • a stack bottom and a vertical stack wall to which the consignments lie in the stacking tray,
  • an approximately horizontal stacking direction along the stack wall slidable, the stack-holding stack support and
  • a slot in the stack floor with engaging projection of the stack support
having.

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 versenkbar ist.Furthermore, from GB-PS 1 303 135 for upright flat objects to be stacked a stacking device is known in which the stack support is sunk down into the stack level floor.

Beim Entleeren dieser Stapeleinrichtungen, auf eine nachfolgende Aufnahme durch Verschieben des Stapels, ist es nicht sichergestellt, dass dabei keine einzelnen Sendungen am Ende der Stapeleinrichtungen nach unten durchrutschen.When emptying these stacking devices, on a subsequent recording by moving the stack, it is not ensured that this does not slip through individual shipments at the end of the stacking devices down.

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.The invention has for its object to provide a stacking tray with a stack support for stacks of flat items in a standing position in which no empties are removed from the stack composite during emptying and the displacement of the stack.

Erfindungsgemäß wird die Aufgabe durch ein Stapelfach mit den Merkmalen nach Anspruch 1 gelöst.According to the invention the object is achieved by a stacking tray 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 Sendung nach oben mitgerissen, und dünne Sendungen können beim Verschieben infolge der Verzahnung nicht zwischen Stapelstütze und Stapelboden rutschen.The stack support is designed to be retractable at the bottom of the stacking tray down into the stacking floor level. The stack floor is designed at least partially profiled and running the stack support with her in the raised, the stack on the falling-hindering state, on the bottom of the pile sliding surface with the soil profile. As a result, no transmission is entrained upward, and thin broadcasts can not slip between stack support and stacking floor when moving due to the teeth.

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

Das Versenken der Stapelstütze kann auf verschiedene vorteilhafte Art und Weise durchgeführt werden.
So kann die Stapelstütze am Ende des Stapelfaches in Stapelrichtung 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 übernimmt dann ein anderer Stützmechanismus, der von oben heruntergefahren wird, der aber nicht Erfindungsgegenstand ist, die Aufgabe der Stapelstütze.The sinking of the stack support can be carried out in various advantageous ways.
Thus, the stack support at the end of the stacking tray in the stacking direction down in the plane of the stack bottom are performed pivotally. The stack support then takes over in the swung-down state, the function of the stack floor for bridging, so that the stack can be pushed without interruption on a subsequent support surface. For this purpose, then takes over another support mechanism, which is shut down from above, but which is not the subject of the invention, 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 heruntergefahrenen 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 befindliche Abschlussrand des Stapelbodens profiliert ausgeführt und die dem profilierten Abschlussrand des Stapelbodens beim vertikalen Verfahren zugewandte Fläche der Stapelstütze so profiliert, 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 Sägezahnprofil, wobei die steilen Flanken zur Stapelwand gerichtet sind. Dadurch bleiben die Sendungen an den steilen Flanken hängen.It is also advantageous if the stack support is vertically movable at the end of the stack bottom and has at its upper edge in the shut down state approximately parallel to the stack bottom aligned part for bridging a gap between the stack bottom and a subsequent support surface. In this case, the end edge of the stack bottom located in the stacking direction is profiled and profiled the profiled end edge of the stack bottom during vertical process facing surface of the stack support so that when closing it meshes with the profiled edge of the stack bottom. This intermeshing profiling prevents any consignment from sliding between the pile bottom and the pile support.
The vertical method of the stack support can be advantageously realized by pivoting the stack support in the plane of the stack bottom perpendicular to the stacking direction.
In order to prevent slippage of the items from the stack wall, the stack bottom advantageously has a sawtooth profile, the steep flanks being directed towards the stack wall. This keeps the shipments hanging on the steep flanks.

Vorteilhaft ist es auch, wenn die Oberfläche des im heruntergefahrenen Zustand annähernd parallel zum Stapelboden ausgerichteten Teils der Stapelstütze das gleiche Oberflächenprofil wie der Stapelboden aufweist.It is also advantageous if the surface of the part of the stack support aligned in the shutdown state approximately parallel to the stack bottom has the same surface profile as the stack bottom.

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

Entsprechend FIG 1 werden die Sendungen 1 in aufrechter Position hintereinander in einem Deckbandsystem zwischen Transportriemen 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 Weichenanordnung mit einem Weichenflügel 3, um Sendungen 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 Sägezahnform 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.
Um genügend Platz für das Schwenkgelenk zu haben, hat die Stapelwand 6 in diesem unteren Bereich einen zurückgesetzten Teil.According to FIG. 1, the items 1 are transported in an upright position one behind the other in a shroud system between transport belts 2, along adjacent stacking compartments 5 of a sorting machine. Each stacking compartment 5 consists of a stacking bottom 7 and a stacking wall 6 perpendicular thereto. Before each stacking compartment 5 there is a diverter arrangement with a diverter vane 3 in order to eject mail items in a targeted manner 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 tray 5 to a stack support 8 or to the last shipment of an already existing stack 11. There they are braked on the stack wall 6 and aligned. The stack support 8 is displaceable along the stack wall 6 against a directed to the stacking point spring force and pivotally guided in the stack level.
The stack bottom 7 is, as can be seen in FIG 1, designed profiled in sawtooth shape, wherein the sawtooth edges parallel to the stacking wall 6 and the steep edges of the stack wall 6 are facing. The stack support 8 has the same profiling on its lower side sliding on the stack bottom 7 (FIG. 4), so that both profiles mesh with one another. As a result, no thin and flexible items 1 between stacking tray 7 and stack support 8 slip and rebounding or sliding of the stacking wall 6 is largely avoided.
In order to have enough space for the pivot joint, the stacking wall 6 has a recessed portion in this lower area.

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 Auflagefläche 12 fallen, besitzt die Stapelstütze 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.
Die Sendungen 1 müssten also mit ihren Schmalseiten in diesem Sägezahnprofil verlaufen, um zwischen Stapelbodenrand und Stapelstütze 8 zu gelangen, was aufgrund ihrer Eigensteifigkeit 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 weiteren 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 gefahren, die dann den Stapel 11 stützen, so dass die Einstapeleinrichtung 4 wieder in die Ausgangsstellung gebracht werden kann.When stacking the directed along the stacking wall 6 movement component of the programs 1 generates a force that moves the stack support 8 against the spring force of the stacking point away. Is the stack 11 with the stack support 8 at the end of the stacking tray 5, either because the stack 11 is correspondingly large or because of the stacking device 4 and the stack support 8 held stack 11 by moving the stacking device 4 by means of a connected thereto push rod 10th has been moved accordingly, the swinging down the stack support 8 takes place according to FIG 2 and 3 in order to push the stack 11 on a subsequent support surface 12 can. So that the shipments 1 of the stack 11 do not fall into the gap between the stacking bottom 7 and the support surface 12, the stack support 8 has at its upper edge an approximately parallel to the stacking bottom 7 aligned in the lower end part 9, which bridges the gap at completely heruntergeschwenkter stack support 8 , the support surface 12 overlapping. Since thin shipments 1 could also slip between stacking floor 7 and stack support 8, both the end edge 15 of the stack bottom 8 located in the stacking direction and the surface 16 of the stack support 8 facing the end edge 15 during pivoting are profiled in such a way that they mesh with one another. The profile is also designed as a sawtooth, the profile on the stack support side is circular arc because of the pivoting movement.
The shipments 1 would thus have to run with their narrow sides in this sawtooth to get between the stack bottom edge and stack support 8, which does not take place due to their inherent rigidity. Before the stack support 8 is pivoted at the end of the stacking tray 5 down, an unillustrated external support mechanism is moved next to the stack support 8. When Nachuntenschwenken the stack support of the support mechanism takes over the stack 11 and then continues to drive controlled in the further process of the stack 11. Are all broadcasts 1 of the stack 11 on the support surface 12, 13 support fingers 14 are driven through the recesses, which then support the stack 11, so that the stacking device 4 can be brought back into the starting position.
