Abstract

The aim of the invention is to portion a stack (4) of thin postal items sitting adjacent on a support with at least one movable holding support (5) and a belt conveyor. To this end, the support has a stationary, horizontally oriented part (1) and an adjacent pivotable part (2) which can be pivoted about a pivoting axis (3) which is located at the outer margin in the direction of stacking. During portioning, the pivotable part which extends transversely from the stationary part downwards is swiveled into a horizontal position. Below the stationary part at the border to the movable part a holding support (6) with a belt conveyor is arranged. Said belt conveyor is driven when swiveled downwards. An additional support (7) is arranged at the frame of the pivotable part of the support just above the postal items. Said additional support retains the remaining stack on the stationary support. The portioned and then compressed stack is located between the holding supports (5, 6) with belt conveyors and is reloaded by the action of the drive of said belt conveyors.

In der FIG 1a ist eine Unterlage zu erkennen, die aus einem horizontal ausgerichteten, fest angeordneten Teil 1 und aus einem sich anschließenden, schräg nach unten verlaufenden und um eine in Stapelrichtung am Ende der Unterlage befindliche Schwenkachse 3 schwenkbaren Teil 2 besteht. Auf der Unterlage befindet sich ein Stapel 4 mit geringem Stapeldruck nebeneinander stehender flacher Sendungen, die am Ende von einer als Transportbänder ausgebildeten verfahrbaren Haltestütze 5 gehalten wird.In Figure 1a, a base can be seen, which consists of a horizontally aligned, fixed part 1 and out a subsequent, obliquely downward and around one in the stacking direction at the end of the base Pivot axis 3 pivotable part 2 is made. On the pad there is a stack 4 with low stack pressure side by side standing flat broadcasts that end at one as Conveyor belts trained movable support 5 held becomes.

Diese Haltestütze 5 besitzt einen den Sendungsdruck aufnehmenden Sensor und wird so verfahren, daß der gewählte Sendungsdruck eingehalten wird. Die Befüllung der Vorrichtung erfolgt von links mit einem geringen Stapeldruck. Auf der linken, nicht dargestellten Seite wird der Stapel 4 mit Sendungen aus anderen Behältern gespeist, indem die Sendungen aus diesen Behältern entfernt, in Richtung der schon auf der Unterlage stehenden Sendungen verschoben und mit diesen vereinigt werden. Dabei werden die Sendungen mit horizontal verfahrbaren und schwenkbaren Haltestützen gehalten. An der Grenze zwischen dem fest angeordneten Teil 1 und dem schwenkbaren Teil 2 der Unterlage unter dem fest angeordneten Teil 1 befindet sich eine weitere als vertikal ausgerichtete Transportbände ausgeführte Haltestütze 6.This support bracket 5 has a consignment pressure Sensor and is moved so that the selected shipment pressure is observed. Filling the device takes place from the left with a small stack pressure. On the left, not shown, the stack 4 with shipments fed from other containers by the shipments removed from these containers, in the direction of that already on the Documentary items moved and merged with them become. The shipments are moved horizontally and swiveling support brackets. At the Border between the fixed part 1 and the pivotable Part 2 of the document under the fixed part 1 there is another as a vertically aligned conveyor belt Support bracket 6.

Befindet sich der zu portionierende Gesamtstapel 4 vollständig auf der Unterlage, so wird er portioniert, indem der schwenkbare Teil 2 um die Schwenkachse 3 mittels eines nicht dargestellten Antriebsmechanismus nach unten in eine horizontal ausgerichtete Lage geschwenkt wird. Während des Schwenkvorganges werden die Transportbänder der Haltestütze 6 nach unten angetrieben. Dadurch wird erreicht, daß an der Grenze zwischen dem oberen verbliebenen und dem unteren portionierten Stapel keine Sendungen zwischen beiden Stapeln stecken bleiben. Um ein Abkippen des oberen Stapels zu verhindern, ist am schwenkbaren Teil 2 der Unterlage an der Trennstelle zwischen den Unterlagenteilen 1,2 dicht über den höchsten vorgesehenen Sendungen eine Zusatzstütze 7 angebracht. Beim Herunterschwenken bewegt sich die Zusatzstütze 7 ebenfalls nach unten und hält somit den verbliebenen Stapel.The total stack 4 to be portioned is completely on the base, it is portioned by the pivotable part 2 about the pivot axis 3 by means of a not illustrated drive mechanism down into a horizontal aligned position is pivoted. During the swiveling process the conveyor belts of the support bracket 6 after driven below. This ensures that at the border between the top remaining and the bottom portioned Do not stack any items between the two stacks stay. To prevent the top stack from tipping over, is on the pivotable part 2 of the pad at the separation point between the underlay parts 1, 2 just above the highest provided programs an additional support 7 attached. At the The additional support 7 also moves downward down and thus holds the remaining stack.

Die Zusatzstütze 7 kann ebenfalls Transportbänder besitzen. Werden beim Schwenken die Transportbänder mit der Schwenkgeschwindigkeit nach oben angetrieben, so werden dabei auf die Sendungen keine Kräfte mit vertikaler Kraftkomponente ausgeübt. Nach Beendigung des Schwenkvorganges wird die verfahrbare Haltestütze 3 so nach innen bewegt, daß sich ein gewählter höherer Stapeldruck einstellt (FIG 1c).The additional support 7 can also have conveyor belts. When swiveling the conveyor belts at the swiveling speed driven upwards, so be on the Shipments exerted no forces with a vertical force component. After the swiveling process is completed, the movable Support bracket 3 moves inwards so that a selected sets higher stack pressure (FIG 1c).

Unter der Unterlage 2 befinden sich zwei nach außen schwenkbare Längsträger 8 und darunter ein oben offener Behälter 9 mit schrägen Seitenwänden.Under the pad 2 there are two pivoting outwards Side members 8 and below that a container 9 open at the top with sloping side walls.

In den folgenden Schnittdarstellungen werden die nacheinander ablaufenden Umladevorgänge näher dargestellt.
Als erstes wird gemäß FIG 2a die Unterlage 2 seitlich unter dem Stapel herausgezogen, wobei die Längsträger 8 so befestigt sind, daß die Entfernung der Unterlage 2 nicht behindert und der Sendungsstapel durch einen Anschlag 12 in seiner Position gehalten wird. Danach wird, wie der FIG 2b zu entnehmen ist, der Behälter 9 mit entsprechenden Hebemitteln 10 von einer Rollenbahn 11 soweit angehoben, daß sich die Längsträger 8 und die Sendungen mit ihren unteren Teilen unterhalb des oberen Randes der Seitenwände der Behälter 9 befinden. Anschließend erfolgt das mit den Pfeilen angedeutete Nachaussenschwenken der Längsträger (8). In der nächsten Phase (FIG 2c) werden die Transportbänder der den Sendungsstapel unter einem festgelegten Stapeldruck haltenden Haltestützen 5,6 so angetrieben, daß der Stapel zum Behälterboden hin bewegt wird. Nachdem der Sendungsstapel auf dem Behälterboden steht, wird der Behälter 9 mit Hilfe der Hebemittel 10 wieder auf die Rollenbahn 11 abgesenkt (FIG 2d), mittels der er dann abtransportiert wird (FIG 2e). Die verfahrbare Haltestütze 5 wird an den verbliebenen Sendungsstapel auf dem fest angeordneten Teil 1 der Unterlage bewegt, der bewegliche Teil 2 der Unterlage wird wieder nach oben geschwenkt, und die Unterlage wird weiter beladen.The successive reloading processes are shown in more detail in the following sectional views.
First, according to FIG. 2a, the base 2 is pulled out laterally under the stack, the longitudinal beams 8 being fastened in such a way that the removal of the base 2 is not hindered and the stack of mail items is held in position by a stop 12. Thereafter, as can be seen in FIG. 2b, the container 9 is raised with appropriate lifting means 10 from a roller conveyor 11 to such an extent that the longitudinal members 8 and the mail items with their lower parts are located below the upper edge of the side walls of the containers 9. Then the outward pivoting of the side members (8), indicated by the arrows, takes place. In the next phase (FIG. 2c), the conveyor belts of the support supports 5, 6, which hold the stack of mail items under a fixed stack pressure, are driven such that the stack is moved toward the bottom of the container. After the stack of mail items is on the bottom of the container, the container 9 is lowered again onto the roller conveyor 11 with the aid of the lifting means 10 (FIG. 2d), by means of which it is then transported away (FIG. 2e). The movable support 5 is moved to the remaining batch of mail on the fixed part 1 of the base, the movable part 2 of the base is pivoted up again, and the base is further loaded.

Wie in FIG 2a-e angegeben, besitzt jede Haltestütze 5,6 drei Transportbänder. Die Länge der Transportbänder ist so ausgeführt, daß der Stapel sicher in den Behälter 9 transportiert wird.As indicated in FIG 2a-e, each support bracket 5.6 has three Conveyor belts. The length of the conveyor belts is designed that the stack is transported safely into the container 9 becomes.

Je nach konkreter Ausführung kann es dabei notwendig sein, zum ungehinderten Abtransport der Behälter 9 die Haltestützen 5,6 nach oben zu bewegen. Ist in einem konkreten Fall der Stapel kleiner als das Fassungsvermögen des Behälters 9, so daß die Sendungen im Behälter 9 umkippen könnten, wird in den Behälter 9 eine an die Behälterseitenwände festklemmbare Halterung eingesetzt. Diese Halterung ist so geformt, daß die Haltestützen 5,6 Platz zum Eintauchen in den Behälter 9 haben.Depending on the specific version, it may be necessary the support brackets for unhindered removal of the containers 9 5.6 to move up. In a specific case it is Stack smaller than the capacity of the container 9, so that the shipments in container 9 could tip over is in the Container 9 is a clamp which can be clamped to the container side walls used. This bracket is shaped so that the Holding supports 5.6 have space for immersion in the container 9.

Method for forming and portioning a stack (4) of narrow items of mail which stand on edge, one beside the other, on an underlying surface with low stacking pressure, and of transferring a compressed stack portion into a container (9), using the apparatus according to Claims 1 to 7, characterized in that
    the container (9) is arranged beneath the pivotable part (2) of the underlying surface,
    with the stack (4) formed on the underlying surface, the pivotable part (2) is pivoted into its separating position, the transporting device of the further retaining support (6) being driven such that at least the items of mail which are in contact with the transporting device are transported to the underlying surface,
    the separated-off stack portion located on the pivotable part (2) is compressed to a predetermined stacking pressure by means of the displaceable retaining support (5),
    the pivotable part (2) is drawn away laterally from beneath the stack portion, the stack portion being prevented from moving sideways by a stop (12),
    the container (9) is moved upwards until the longitudinal carriers (8) with the stack portion are located within the container (9) to such an extent that the longitudinal carriers (8) can be pivoted away laterally from beneath the stack portion,
    the longitudinal carriers (8) are pivoted away laterally from beneath the stack portion, and the transporting belts of the retaining support (5), which compresses the stack portion, and of the further retaining support (6) are then driven such that the stack portion is moved in the direction of the container base.
  9. Method according to Claim 8, characterized in that the container (9), following the loading operation, is lowered onto a transporting means (11), the longitudinal carriers (8) are pivoted back, the displaceable retaining support (5) is moved onto the end side of the stack portion remaining on the fixed part (1), and in that the pivotable part (2) is then pivoted into its stack-forming position and a stack (4) is formed anew.
