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.

Description

Beschreibungdescription
Vorrichtung und Verfahren zum Bilden, Portionieren und Umladen eines StapelsDevice and method for forming, portioning and reloading a stack
Die Erfindung betrifft das Bilden, Portionieren und Umladen eines Stapels nach den Oberbegriffen der unabhängigen Ansprüche.The invention relates to forming, portioning and reloading a stack according to the preambles of the independent claims.
Bei Bearbeitungs- und Verteilprozessen werden häufig größere Stapel hochkant nebeneinanderstehender flacher Sendungen gebildet, die zur Weiterverarbeitung oder zum Abtransport in Behältern in kleinere Stapel portioniert werden müssen.In processing and distribution processes, larger batches of flat consignments standing side by side are often formed, which must be portioned into smaller batches for further processing or for removal in containers.
Bekannt ist aus DE-OS 24 19 630 eine Vorrichtung, die für eine Zwischenspeicherung von flachen Gegenständen, wie Briefen und Postkarten einen Stapel dieser hochkant stehenden flachen Gegenstände bildet. In US 5 104 114 wird ebenfalls eine Stapelvorrichtung zur Bildung hochkant stehender flacher Sendun- gen beschrieben, bei welcher der Stapel von einer Stapelrolle gegen eine verfahrbare Stützwand gestapelt wird. Die Stapelung erfolgt auf den beweglichen Boden eines Behälters. Bekannt ist aus GB-PS 14 66 892 das Portionieren eines Stapels hochkant stehender flacher Gegenstände durch Abschwenken ei- nes schwenkbaren Unterlagenteils von einem feststehenden Unterlagenteil.From DE-OS 24 19 630 a device is known which forms a stack of these upright flat objects for temporary storage of flat objects such as letters and postcards. US Pat. No. 5,104,114 also describes a stacking device for forming upright, flat mail items, in which the stack is stacked by a stacking roller against a movable support wall. The stacking takes place on the movable bottom of a container. From GB-PS 14 66 892 it is known to portion a stack of upright flat objects by swiveling a pivotable base part from a fixed base part.
In diesen Lösungen ist der Abtransport der Stapel ohne Spe- zialbehälter nicht beschrieben.In these solutions, the removal of the stacks without a special container is not described.
Der in den Ansprüchen 1, 7 und 8 angegebenen Erfindung liegt deshalb die Aufgabe zugrunde, einen Stapel von auf einer Unterlage hochkant nebeneinander mit geringem Stapeldruck zwischen zwei verfahrbaren Haltestützen stehenden schmalen Sendungen automatisch und sicher zu portionieren und einen kom- primierten Stapel sicher umzuladen, wobei zum Abtransport der Stapel keine aufwendigen Spezialbehälter notwendig sind. Erfmdungsgemaß wird durch die Unterlage, bestehend aus einem fest angeordneten, horizontal ausgerichteten Teil und einem sich anschließenden schwenkbaren Teil, der beim Befullen der Unterlage schräg nach unten verlauft und beim Portionieren nach unten in eine ebenfalls horizontale Position geschwenkt wird, und durch die Sendungen vertikal verschiebende Haltestutzen ein sicheres und aufwandsarmes Portionieren der Stapel und ein Beladen von Behaltern mit den Stapelportionen unter einem festgelegten Stapeldruck gewahrleistet.The invention specified in claims 1, 7 and 8 is therefore based on the object of automatically and safely portioning a stack of narrow consignments standing upright on a support side by side with low stack pressure between two movable holding supports and reliably reloading a compressed stack, whereby No expensive special containers are required to remove the stacks. According to the invention, the base, consisting of a fixedly arranged, horizontally oriented part and a subsequent swiveling part, which runs obliquely downwards when filling the base and is pivoted downwards into a likewise horizontal position when portioning, and vertically displacing the items Holding spout ensures safe and effortless portioning of the stacks and loading containers with the stack portions under a specified stack pressure.
Vorteilhafte Ausgestaltungen sind in den Unteranspruchen dargestellt .Advantageous embodiments are shown in the subclaims.
Vorteilhaft ist es nach Anspruch 2, die den verbleibenden Stapel stutzende Zusatzstutze als senkrecht zur schwenkbaren Unterlage ausgerichtetes, angetriebenes Transportband auszufuhren und dieses beim Herunterschwenken des schwenkbaren Teils der Unterlage so anzutreiben, daß auf die Sendungen durch die stutzende Bandflache keine vertikal gerichtete Kraft ausgeübt wird. Dadurch werden unzulässige Beanspruchungen von insbesondere empfindlichen Sendungen vermieden.It is advantageous according to claim 2, to execute the remaining stack supporting additional support as a vertically aligned to the swiveling support driven conveyor belt and to drive it when swiveling down the swiveling part of the support so that no vertical force is exerted on the mail items by the supporting belt surface. This avoids inadmissible stresses on particularly sensitive shipments.
Nach Anspruch 3 ist es vorteilhaft, auch die verfahrbare Haltestutze am schwenkbaren Teil der Unterlage als antreibbares Transportband auszufuhren. Damit ist es möglich, die komprimierte Stapelportion sicher in Richtung eines Behalters zu transportieren.According to claim 3, it is advantageous to perform the movable support bracket on the pivotable part of the base as a drivable conveyor belt. This makes it possible to safely transport the compressed stack portion in the direction of a container.
Damit die Stapelportion m einen Behalter geladen werden kann, ist es nach Anspruch 4 vorteilhaft, den schwenkbaren Teil der Unterlage seitlich entfernbar aus dem Bereich der Stapelportion auszufuhren.So that the stack portion can be loaded into a container, it is advantageous according to claim 4 to carry out the pivotable part of the base laterally removable from the area of the stack portion.
Vorteilhaft ist nach Anspruch 5, unter dem entfernbaren Teil der Unterlage zwei parallel verlaufende, nach außen schwenkbare Langstrager anzuordnen, unter denen sich wiederum ein oben offener Behalter mit schräg nach außen verlaufenden Sei- tenwanden befindet.It is advantageous according to claim 5, under the removable part of the base to arrange two parallel, outwardly pivotable long beams, among which in turn the open container at the top with the side walls running diagonally outwards.
Nach Anspruch 6 kann der Behalter mittels Hebemittel in der Hohe verfahren werden. Dadurch ist es möglich, die gehaltene Stapelportion teilweise in den Behalter eintauchen zu lassen und dann die Langstrager zur Seite in den durch die schräg nach außen verlaufenden Seitenwande gebildeten seitlichen Raum zu schwenken. Damit ist sichergestellt, daß die Sendun- gen sicher m den Behalter überfuhrt werden.According to claim 6, the container can be moved in height by means of lifting means. This makes it possible to partially immerse the portion of the stack held in the container and then to pivot the long supports to the side into the lateral space formed by the obliquely outwardly extending side walls. This ensures that the consignments are safely transferred to the container.
Ist das Beladen des Behalters beendet, wird in vorteilhafter Ausgestaltung nach Anspruch 9 dieser auf ein Transportmittel zum Abtransport abgesenkt, die verfahrbare Haltestutze an den verbliebenen Sendungsstapel auf dem fest angeordneten Teil der Unterlage gefahren. Dann wird der bewegliche Teil der Unterlage wieder nach oben geschwenkt und die Unterlage wird weiter beladen.If the loading of the container has ended, in an advantageous embodiment according to claim 9, the container is lowered onto a means of transport for removal, the movable holding support is moved to the remaining stack of mail items on the fixedly arranged part of the base. Then the movable part of the pad is swung up again and the pad is loaded further.
Anschließend wird die Erfindung in einem Ausfuhrungsbeispiel anhand der Zeichnung naher erläutert. Dabei zeigenThe invention is explained in more detail in an exemplary embodiment with reference to the drawing. Show

In der FIG la 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 Transportbander ausgebildeten verfahrbaren Haltestutze 5 ge- halten wird.AA of FIG lc of successive processes when loading the container. In FIG la a base can be seen, which consists of a horizontally oriented, fixed part 1 and a subsequent, obliquely downward and pivotable about a pivot axis 3 located in the stacking direction at the end of the base part 2. On the base there is a stack 4 of flat consignments standing side by side with a low stack pressure, which is held at the end by a movable support bracket 5 designed as a conveyor belt.
Diese Haltestutze 5 besitzt einen den Sendungsdruck aufnehmenden Sensor und wird so verfahren, daß der gewählte Sendungsdruck eingehalten wird. Die Befullung 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 ver- einigt werden. Dabei werden die Sendungen mit horizontal verfahrbaren und schwenkbaren Haltestutzen 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 Trans- portbande ausgeführte Haltestutze 6.This support bracket 5 has a sensor that receives the mailing pressure and is moved so that the selected mailing pressure is maintained. The device is filled from the left with a low stack pressure. On the left-hand side, not shown, the stack 4 is fed with mail items from other containers by removing the mail items from these containers, moving them in the direction of the mail items already on the base and combining them. The shipments are held with horizontally movable and swiveling holding sockets. At the boundary between the fixed part 1 and the pivotable part 2 of the base under the fixed part 1 there is a further support bracket 6 designed as a vertically oriented conveyor belt.
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. Wahrend des Schwenkvorganges werden die Transportbander der Haltestütze 6 nach unten angetrieben. Dadurch wird erreicht, daß an der Grenze zwischen dem oberen verbliebenen und dem unteren portionier- ten 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 Zusatzstutze 7 angebracht. Beim Herunterschwenken bewegt sich die Zusatzstutze 7 ebenfalls nach unten und halt somit den verbliebenen Stapel.If the entire stack 4 to be portioned is completely on the base, it is portioned by pivoting the pivotable part 2 downward about the pivot axis 3 by means of a drive mechanism, not shown, into a horizontally oriented position. During the pivoting process, the conveyor belts of the support bracket 6 are driven downwards. This ensures that no mail items get stuck between the two stacks at the boundary between the upper remaining and the lower portioned batch. In order to prevent the upper stack from tipping over, the swiveling part 2 of the base is at the separation point an additional support 7 is attached between the supporting parts 1, 2 just above the highest intended mail items. When swiveling down, the additional support 7 also moves down and thus holds the remaining stack.
Die Zusatzstutze 7 kann ebenfalls Transportbander besitzen. Werden beim Schwenken die Transportbander mit der Schwenkgeschwindigkeit nach oben angetrieben, so werden dabei auf die Sendungen keine Kräfte mit vertikaler Kraftkomponente ausge- übt. Nach Beendigung des Schwenkvorganges wird die verfahrbare Haltestütze 3 so nach innen bewegt, daß sich ein gewählter höherer Stapeldruck einstellt (FIG lc) .The additional support 7 can also have conveyor belts. If the conveyor belts are driven upwards with the swiveling speed during swiveling, no forces with vertical force components are exerted on the mail items. After the swiveling process has ended, the movable holding support 3 is moved inwards in such a way that a selected higher stack pressure is established (FIG. 1c).
Unter der Unterlage 2 befinden sich zwei nach außen schwenk- bare Langstrager 8 und darunter ein oben offener Behalter 9 mit schrägen Seitenwanden.Under the base 2 there are two long beams 8 which can be swiveled outwards and below which a container 9 open at the top with sloping side walls.
In den folgenden Schnittdarstellungen werden die nacheinander ablaufenden Umladevorgange naher dargestellt. Als erstes wird gemäß FIG 2a die Unterlage 2 seitlich unter dem Stapel herausgezogen, wobei die Langstrager 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 ent- nehmen ist, der Behalter 9 mit entsprechenden Hebemitteln 10 von einer Rollenbahn 11 soweit angehoben, daß sich die Langstrager 8 und die Sendungen mit ihren unteren Teilen unterhalb des oberen Randes der Seitenwande der Behalter 9 befinden. Anschließend erfolgt das mit den Pfeilen angedeutete Nachaus- senschwenken der Langstrager (8) . In der nächsten PhaseIn the following sectional views, the successive reloading processes are shown in more detail. First, according to FIG. 2a, the support 2 is pulled out laterally under the stack, the long supports 8 being fastened in such a way that the removal of the support 2 is not impeded 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 the appropriate lifting means 10 from a roller conveyor 11 to such an extent that the long beams 8 and the mail items with their lower parts are located below the upper edge of the side walls of the container 9. Then the long beams (8) are pivoted outwards as indicated by the arrows. In the next phase
(FIG 2c) werden die Transportbander der den Sendungsstapel unter einem festgelegten Stapeldruck haltenden Haltestutzen 5,6 so angetrieben, daß der Stapel zum Behalterboden hin bewegt wird. Nachdem der Sendungsstapel auf dem Behalterboden steht, wird der Behalter 9 mit Hilfe der Hebemittel 10 wieder auf die Rollenbahn 11 abgesenkt (FIG 2d) , mittels der er dann abtransportiert wird (FIG 2e) . Die verfahrbare Haltestutze 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.(FIG. 2c), the conveyor belts of the holding stub 5, 6 that hold the stack of 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 container floor, 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 bracket 5 is moved to the remaining stack of mail items on the fixed part 1 of the base, the movable part 2 of the base is pivoted upwards 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 so that the stack is safely transported into the container 9.
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 Hal- terung eingesetzt. Diese Halterung ist so geformt, daß die Haltestützen 5,6 Platz zum Eintauchen in den Behälter 9 haben. Depending on the specific design, it may be necessary to move the support brackets 5, 6 upwards to allow the containers 9 to be transported away without hindrance. If, in a specific case, the stack is smaller than the capacity of the container 9, so that the mail items in the container 9 could tip over, a holder which can be clamped onto the container side walls is inserted into the container 9. This bracket is shaped so that the support brackets 5.6 have space for immersion in the container 9.
