Description

Die Erfindung betrifft eine Stapeleinrichtung für Briefsendungen und ähnlich flaches, biegsames Fördergut gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a stacking device for letters and similar flat, flexible conveyed goods according to the preamble of claim 1.

In automatischen Briefverteilanlagen werden die Sendungen zum Zwecke des automatischen Lesens des Bestimmungsortes und des späteren Einsortierens auf einer Förderstrecke vereinzelt transportiert und über eine Fachstrecke mit Weichen entsprechend den Postleitzahlgebieten einer Vielzahl von Stapelfächern zugeordnet und abgestapelt.In automatic mail distribution systems, the items are transported individually on a conveyor line for the purpose of automatic reading of the destination and later sorting and assigned and stacked over a specialist line with switches corresponding to the postcode areas to a large number of stacking compartments.

Um einen möglichst hohen Durchsatz zu erzielen, laufen die Sendungen auf dem Transportband mit möglichst hoher Geschwindigkeit und möglichst geringen Abständen. Unter diesen Umständen tritt bei Sendungen, die dem gleichen Stapelfach zugeordnet sind, das Problem der Stauung auf, der durch ein Auflaufen der Vorderkante der nachfolgenden Sendung auf die Hinterkante der vorauslaufenden Sendung verursacht wird.In order to achieve the highest possible throughput, the consignments run on the conveyor belt with the highest possible Speed and the smallest possible distances. Under these circumstances, the problem of congestion arises in the case of mail items which are assigned to the same stacking compartment, which is caused by the front edge of the subsequent item running onto the rear edge of the preceding item.

Aus der DO-OS 33 17 865 ist es bekannt, bei senkrecht, auf der Längskante beim Stapeln ruhenden Sendungen die untere Vorderkante der Sendung tangential in ein sich drehendes Spindelrad einlaufen zu lassen, wobei im Zuge des Einlaufens der Sendung in das Stapelfach die Flanke des Spindelrades die nachfolgenden Teile der Sendung, insbesondere deren hinteren Bereich, in Richtung der bereits gestapelten Sendungen befördert, so daß die nachfolgende Sendung mit Sicherheit neben der vorausgegangenen Sendung in das Stapelfach einläuft.From DO-OS 33 17 865 it is known to let the lower front edge of the shipment enter tangentially into a rotating spindle wheel in the case of mail items resting vertically on the longitudinal edge when stacked, the flank of the Spindelrades the following parts of the shipment, in particular the rear area, in the direction of the already stacked shipments, so that the subsequent shipment surely arrives next to the previous shipment in the stacking compartment.

Der Spindelradantrieb je Stapelfach ist jedoch sehr aufwendig und kostspielig. Für Feinverteilanlagen mit einer großen Anzahl von Stapelfächern kleiner Kapazität und geringerem Durchsatz wurde daher versucht die aufwendige Spindelradlösung dadurch zu vermeiden, daß die Sendungen in den Stapelfächern übereinander gestapelt werden und unter Ausnutzung der Schwerkraft die vorauslaufende Sendung infolge ihres Gewichts und ihrer Biegesteifigkeit sich von alleine so weit absenkt, daß die nachfolgende Sendung sich über die vorauslaufende Sendung schiebt. Hier treten jedoch dann Schwierigkeiten auf, wenn die Sendungen, wie z.B. Luftpostbriefe, sehr weich sind, und die Sortierleistung einen vorgegebenen Wert nicht unterschreiten soll.However, the spindle wheel drive per stacking compartment is very complex and costly. For fine distribution systems with a large number of stacking compartments of small capacity and lower throughput, the complex spindle wheel solution was therefore attempted to be avoided by stacking the items in the stacking compartments and using gravity to take advantage of the preceding item due to its weight and bending rigidity lowers the fact that the following program pushes itself over the preceding program. Difficulties arise here, however, when the items, such as airmail letters, are very soft and the sorting performance should not fall below a predetermined value.

Der Erfindung liegt die Aufgabe zugrunde, bei einer Stapeleinrichtung der im Oberbegriff des Patentanspruchs 1 genannten Art die genannten Schwierigkeiten zu vermeiden. Insbesondere soll bei einfachereren Briefverteilanlagen die Einstapelung betriebssicher gemacht werden, so daß auch bei Sendungen mit geringer Biegesteifigkeit mit möglichst hoher Einstapelgeschwindigkeit ein auflauffreies Einstapeln von für das gleiche Stapelfach bestimmten Sendungen erreicht wird.The invention has for its object to avoid the difficulties mentioned in a stacking device of the type mentioned in the preamble of claim 1. In particular, in the case of simpler mail distribution systems, the stacking is to be made operationally reliable, so that, even in the case of mail items with low bending stiffness, the stacking speed of mail items destined for the same stacking compartment is achieved with the highest possible stacking speed.

Die Aufgabe wird bei einer Stapeleinrichtung der im Oberbegriff des Patentanspruchs 1 genannten Art durch die in seinem kennzeichnenden Teil genannte Erfindung gelöst. Durch eine einfache, wenig Aufwand erfordernde zusätzliche Leitvorrichtung wird vor allem die Hinterkante einer Sendung vor dem Eintreffen der Vorderkante der nachfolgenden Sendung so weit niedergedrückt, daß die nachfolgende Sendung sich ungehindert über die vorauslaufende Sendung schiebt. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung sind in den Unteransprüchen angegeben.The object is achieved in a stacking device of the type mentioned in the preamble of claim 1 by the invention mentioned in its characterizing part. By means of a simple additional guide device requiring little effort, the trailing edge of a consignment in particular is depressed so far before the arrival of the leading edge of the consecutive consignment that the consecutive consignment moves freely over the preceding consignment. Advantageous refinements and developments of the invention are specified in the subclaims.

Die am Einlaufbügel angebrachte zusätzliche Leitvorrichtung kann ganz oder teilweise aus federndem Material bestehen. Bei Ausgestaltung der Erfindung nach Anspruch 3 kann die zusätzliche Leitvorrichtung mittels einer Spiralfeder vorgespannt werden oder in sehr einfacher Weise ihre Funktion unter Ausnutzung der Schwerkraft ausführen. Die Weiterbildung der Erfindung nach den Ansprüchen 6 und 7 unterstützt die Wirkung der zusätzlichen Leitvorrichtung, schont die Sendungen und bewirkt ein falten- und knickfreies Ablegen der Sendung im Spapelfach.The additional guide device attached to the inlet bracket can consist entirely or partially of resilient material. In an embodiment of the invention according to claim 3, the additional guide device can be biased by means of a spiral spring or can perform its function in a very simple manner using gravity. The development of the invention according to claims 6 and 7 supports the effect of the additional guiding device, protects the mail items and causes the mail item to be stored in the stacking compartment without folds or kinks.

Der Oberbegriff des Patentanspruchs 1 geht aus dem amerikanischen Patent US-A-3 092 380 hervor.The preamble of claim 1 emerges from the American patent US-A-3 092 380.

Ein anderes Beispiel von Stapeleinrichtungen ist aus dem amerikanischen Patent US-A-3 124 352 bekannt.Another example of stackers is known from U.S. Patent No. 3,124,352.

Die Erfindung wird nun anhand von Zeichnungen beispielsweise näher erklärt. Es zeigen im Einzelnen:

Fig. 1 zeigt die Seitenansicht zweier Fachstrecken einer Brieffeinverteilanlage, die aus einer großen Anzahl von übereinanderliegenden und nebeneinander angeordneten Stapelfachern 10 kleiner Kapazität besteht. Die Stapelfächern haben gebenüber der Waagrechten eine Neigung um den Winkel α, um den Sendungen, wie z.B. Karten und Briefe, - im Folgenden abgekürzt "Briefe" genannt -an der Anschlagseite 6 eine stabile Ruhelage zu geben. Die Briefe werden mittels Transportbänder mit ihrer Fläche senkrecht zur Bildebene von rechts kommend in Pfeilrichtung in Weichen den ihren Postleitzahlen zugeordneten Stapelfächern zugeführt.Fig. 1 shows the side view of two sections of a fine letter distribution system, which consists of a large number of stacked compartments 10 arranged next to each other and small capacity. The stacking compartments have an inclination above the horizontal by the angle α, around the items such as Cards and letters - in the following abbreviated "letters" - to give a stable rest position on the stop page 6. The letters are conveyed by means of conveyor belts with their surface perpendicular to the image plane coming from the right in the direction of the arrow in switches to the stacking compartments assigned to their postcodes.

In Fig. 2 ist ein einzelnes Stapelfach 10 dargestellt. Der dem Stapelfach zugeordnete Brief wird durch ein sogenanntes Deckbandsystem, bestehend aus einem Transportriemen 3, einer dem Stapelfach 10 zugeordneten Transportrolle 4 dem Stapelfach zugeführt, und bei einer entsprechend gestellten Weiche 5 zum Verlassen des Transportriemens 3 gezwungen. Über eine Einlauföffnung 12 läuft dann der Brief 11 in das Stapelfach ein, gleitet entlang der Decke des Stapelfaches und der Unterkante eines Einlaufbügels 1 normalerweise über die Hinterkante des vorauslaufenden Briefs 9 auf die bereits gestapelten Briefe 8. Infolge der Neigung des Stapelbodens 7 und damit des Stapelfaches 10 um den Winkel α zur Waagrechten ist gewährleistet, daß die Briefe ordnungsgemäß bis zur Anschlagwand 6 gleiten. Der Einlaufbügel 1 drückt mit seinem abgeflachten Ende 15 in einem Abstand von der Anschlagwand 6 auf die gestapelten Briefe, so daß jeweils der zuletzt eingelaufene Brief infolge seiner Biegesteifigkeit veranlaßt wird, sich auf die bereits gestapelten Briefe abzusenken. Dem Absenken der Briefhinterkante wirkt in unerwünschter Weise, das zu verdrängende Luftpolster sowie die Haftung der Briefe am Einlaufbügel 1 infolge elektrostatischer Aufladungen entgegen.A single stacking compartment 10 is shown in FIG. The letter assigned to the stacking compartment is fed to the stacking compartment by a so-called cover belt system, consisting of a transport belt 3, a transport roller 4 assigned to the stacking compartment 10, and at a correspondingly provided one Switch 5 forced to leave the conveyor belt 3. Via an inlet opening 12, the letter 11 then runs into the stacking compartment, slides along the ceiling of the stacking compartment and the lower edge of an inlet bracket 1, normally over the rear edge of the preceding letter 9 onto the letters 8 already stacked. As a result of the inclination of the stacking base 7 and thus Stacking compartment 10 by the angle α to the horizontal ensures that the letters slide properly up to the stop wall 6. The inlet bracket 1 presses with its flattened end 15 at a distance from the stop wall 6 on the stacked letters, so that the last letter received is caused due to its bending stiffness to lower onto the already stacked letters. The lowering of the trailing edge of the letter has an undesirable effect, the air cushion to be displaced and the adhesion of the letters to the inlet bracket 1 as a result of electrostatic charges.

Um auch großflächige Sendungen geringer Biegesteifigkeit und geringen Gewichts, wie z.B. Luftpostsendungen ordnungsgemäß einstapeln zu können, weist der Einlaufbügel 1 einen winkeleisenförmigen Querschnitt auf, dessen Schenkelenden in Richtung Stepelraum weisen. Hierdurch wird einerseits eine Haftung der Briefe am Einlaufbügel vermieden. Ferner ist im durch die Schenkel des Einlaufbügels 1 mit winkeleisenförmigem Querschnitt gebildeten Zwischenraum eine zusätzliche Leitvorrichtung 2 vorgesehen, die im Einlaufbügels 1 im Bereich seines Lagers 13 befestigt ist, in der Ruhelage einen bestimmten Winkel β zum Einlaufbügel 1 aufweist und in den Zwischenraum des winkeleisenförmigen Querschnitts des Einlaufbügels 1 schwenkbar ist.In order to be able to properly stack even large-area mail items with low bending stiffness and low weight, such as air mail items, the inlet bracket 1 has an angle-iron-shaped cross section, the leg ends of which point in the direction of the staple space. On the one hand, this prevents the letters from sticking to the inlet bracket. Furthermore, an additional guide device 2 is provided in the space formed by the legs of the inlet bracket 1 with an angle iron-shaped cross section, which is fastened in the inlet bracket 1 in the area of its bearing 13, has a certain angle β to the inlet bracket 1 in the rest position and in the space of the angle iron Cross section of the inlet bracket 1 is pivotable.

Beim Einlaufen des Briefes 11 stößt dieser auf die zusätzliche Leitvorrichtung 2 und drückt diese in den durch die Schenkel des Einlaufbügels 1 gebildeten Zwischenraum. Während dieses Vorgangs ist der hintere Teil des Briefes noch von der Transportrolle 4 und dem Transportriemen 3 gefaßt, so daß der Brief beim Anstoßen und bei der Betätigung der zusätzlichen Leitvorrichtung 2 keine Verzögerung erfährt.When the letter 11 arrives, it encounters the additional guide device 2 and presses it into the space formed by the legs of the inlet bracket 1. During this process, the rear part of the letter is still held by the transport roller 4 and the transport belt 3, so that the letter is not delayed when it is pushed and when the additional guide device 2 is actuated.

Durch den kurzen Hebelarm den die Briefe zwischen Transportrolle 4 und zusätzlicher Leitvorrichtung 2 haben, reicht die Beigespannung der Briefe aus, um die jeweilige Briefvorderkante nicht nur an der Stapelfachdecke entlang gleiten zu lassen, sondern auch nach Eindrücken der zusätzlichen Leitvorrichtung 2 sie an der Unterkante des Einlaufbügels 1 entlanggleiten zu lassen. Dagegen wirkt, nachdem die Hinterkante des Briefes die Weiche 5 verlassen hat, die Kraft der zusätzlichen Leitvorrichtung 2 auf den hinteren Teil des Briefes und senkt diesen soweit ab, daß die Vorderkante des nachfolgenden Briefes bei wiederum in den Einlaufbügel 1 eingedrückter zusätzlicher Leitvorrichtung 2 ordnungsgemäß über die vorauslaufende Sendung einläuft.Due to the short lever arm that the letters have between the transport roller 4 and the additional guiding device 2, the additional tension of the letters is sufficient to not only let the respective front edge of the letter slide along the stacking compartment ceiling, but also after the additional guiding device 2 has been pressed in on the lower edge of the Let inlet bracket 1 slide along. On the other hand, after the rear edge of the letter has left the switch 5, the force of the additional guide device 2 acts on the rear part of the letter and lowers it to such an extent that the front edge of the subsequent letter, when the additional guide device 2 is again pressed into the inlet bracket 1, properly over the preceding shipment arrives.

Die gewünschte Ablenkkraft der zusätzlichen Leitvorrichtung 2 kann dadurch realisiert werden, daß bei einseitiger Befestigung der zusätzlichen Leitvorrichtung 2 nahe des Einlaufbügels 13 die zusätzliche Leitvorrichtung 2 ganz oder teilweise aus federndem Material besteht und ohne äußere Krafteinwirkung den in Fig. 2 dargestellten Winkel β zwischen Einlaufbügel 1 und zusätzlicher Leitvorrichtung 2 einnimmt.The desired deflecting force of the additional guide device 2 can be realized in that when the additional guide device 2 is fastened on one side near the inlet bracket 13, the additional guide device 2 consists entirely or partially of resilient material and the angle shown in FIG. 2 without external force β between inlet bracket 1 and additional guide device 2 takes.

Eine andere einfache Ausführungsform ist in Fig. 3 vergrößert dargestellt. Sie sieht vor, daß die zusätzliche Leitvorrichtung 2 und der Einlaufbügel 1 gleiche Drehachsen 13 aufweisen. Die zusätzliche Leitvorrichtung 2 und der Einlaufbügel 1 sind zweiseitige Hebel mit jeweils kurzem Hebelarm 22 bzw. 14. Der kurze Hebelarm 22 der zusätzlichen Leitvorrichtung 2 ist nun so geformt, daß bei Einnahme des Winkels β zwischen zusätzlicher Leitvorrichtung 2 und Einlaufbügel 1 der kurze Hebelarm 22 der zusätzlichen Leitvorrichtung 2 am Einlaufbügel anliegt und dadurch den Winkel β bestimmt. Zur Abspreizung der zusätzlichen Leitvorrichtung 2 um den Winkel β und zur Aufbringung der gewünschten Ablenkkraft kann am Lager 13 eine die zusätzliche Leitvorrichtung 2 auslenkende Spiralfeder vorgesehen sein.Another simple embodiment is shown enlarged in FIG. 3. It provides that the additional guide device 2 and the inlet bracket 1 have the same axes of rotation 13. The additional guide device 2 and the inlet bracket 1 are two-sided levers, each with a short lever arm 22 or 14. The short lever arm 22 of the additional guide device 2 is now shaped such that when the angle β between the additional guide device 2 and inlet bracket 1 is taken, the short lever arm 22 the additional guide device 2 rests on the inlet bracket and thereby determines the angle β. In order to spread the additional guide device 2 by the angle β and to apply the desired deflecting force, a spiral spring deflecting the additional guide device 2 can be provided on the bearing 13.

Eine weitere Ausführungsform der zusätzlichen Leitvorrichtung 2 kommt ohne zusätzliche Spiralfeder aus und nutzt als Auslenkkraft die Schwerkraft.Another embodiment of the additional guide device 2 does not require an additional spiral spring and uses gravity as the deflection force.

In Fig. 4 ist der Schnitt A-A des Stapelfaches, wie aus Fig. 2 ersichtlich ist, dargestellt. Gleiche Teile sind mit gleichen Bezugszeichen versehen, sodaß eine weitere Erläuterung hierzu sich erübrigt. In dieser Darstellung ist deutlich das winkeleisenförmige Profil des Einlaufbügels 1 erkennbar und die im Zwischenrau, der durch die Schenkel des Einlaufbügels gebildet wird, angeordnete zusätzliche Leitvorrichtung 2 sowie das Lager 3 für den Einlaufbügel 1 und gegebenfalls für die zusätzliche Leitvorrichtung 2.4 shows the section AA of the stacking compartment, as can be seen from FIG. 2. The same parts are provided with the same reference numerals, so that a further explanation is unnecessary. In this illustration, the angle-iron-shaped profile of the inlet bracket 1 and the additional guide device 2 arranged in the intermediate space, which is formed by the legs of the inlet bracket, and the bearing 3 for the inlet bracket 1 and, if appropriate, for the additional guide device 2.

Mit 16 ist die geneigte Rückwand bezeichnet, die das Stapelfach 10 trägt und durch ihre Neigung für eine zweite definierte Lage der gestapelten Briefe 8 sorgt.With 16 the inclined rear wall is designated, which carries the stacking compartment 10 and ensures by its inclination for a second defined position of the stacked letters 8.

Unterstützt wird die Wirkung der zusätzlichen Leitvorrichtung 2 durch die Ausgestaltung des langen Endes 15 des Einlaufbügels 1. Es ist in vorteilhafterweise zu einer gleitfläche abgeflacht, wobei die Gleitfläche nahezu parallel zur Oberfläche der gestapelten Briefe gerichtet ist. Eine leichte Wölbung der Gleitfläche in Richtung der Längsachse des Einlaufbügels bewirkt in vorteilhafter Weise, unabhängig von der Höhe der gestapelten Briefe, eine gleichmäßige Reibungskraft auf weitere einlaufende Briefe.The effect of the additional guide device 2 is supported by the design of the long end 15 of the inlet bracket 1. It is advantageously flattened to form a sliding surface, the sliding surface being directed almost parallel to the surface of the stacked letters. A slight curvature of the sliding surface in the direction of the longitudinal axis of the inlet bracket advantageously brings about a uniform frictional force on further incoming letters, regardless of the height of the stacked letters.
