Abstract

The invention relates to a switch point for flat, flexible postal articles in a sorting machine, whereby the postal articles are conveyed in a squeezed manner between two conveyor belts. According to the invention, the deflection element is comprised of two rigid partial deflecting elements (1, 2) which are adjacent in a direction of conveyance, which are interconnected in a fixed manner outside the path of the mail and which have a common pivotal axis (3). The common pivotal axis (3) is situated outside of the conveyor belts (4, 5), said belts continuing while diverging from one another in the switch point area, in the front part of the switch point area with regard to the direction of conveyance. According to the position of the switch point, the corresponding postal article is guided in the selected direction between one of both partial deflecting elements (1, 2) and the respective outer conveyor belts (4, 5), whereby the other partial deflecting element (1, 2) is situated completely outside of the conveyor belts (4, 5) which diverge from one another in the switch point area.

Description

Die Erfindung betrifft eine Weiche für flache, flexible Sendungen in Sendungssortiermaschinen nach dem Oberbegriff des Anspruches 1.The invention relates to a switch for flat, flexible shipments in shipment sorting machines according to the generic term of Claim 1.

Diese Weichen leiten die Sendungen gesteuert in die entsprechenden Transportstränge und Sortierfächer der Sendungssortiermaschinen. Dabei werden die Sendungen in den Transportsträngen zwischen zwei Transportriemen eines Deckbandsystems eingeklemmt transportiert. Die Transportriemen sind schmaler als die Sendungen in ihrer Höhe. Bei entsprechenden bekannten Weichen befindet sich am Ende des Weichenbereiches in Transportrichtung zwischen den beiden Eingängen der abführenden Deckbandsysteme das Schwenklager eines keilförmigen, entgegen der Transportrichtung gerichteten Leitelementes.
Dieses Leitelement bildet je nach Schwenkstellung einen Kanal für die Sendungen zwischen seiner Seitenwand in dem jeweiligen äußeren durchgehenden Transportriemen.
Laufen die Sendungen durch den Weichenbereich, ist es möglich, daß insbesondere gebogene oder geknickte Sendungen gegen das Schwenklager stoßen und eine Störung auslösen. Damit ein ordnungsgemäßer Ablauf in der Sortiermaschine gewährleistet ist, muß sich das Ablenkelement in seiner jeweiligen Endstellung befinden, bevor eine Sendung in die Weiche einläuft. Sollen die Abstände zwischen den Sendungen für einen hohen Maschinendurchsatz möglichst klein gehalten werden, müßten die Ablenkelemente der Weichen schon zu einem Zeitpunkt umschalten, zu dem die vorherige Sendung die Weiche noch nicht verlassen hat. Dies ist aber in diesem Fall nur eingeschränkt möglich, da bei einem zeitigen Umschalten die vorherige Sendung mit ihren hinteren Bereichen gegen einen Transportriemen gedrückt wird, wodurch entweder die Sendung zerstört werden kann oder die Weiche nicht ordnungsgemäß schalten kann.These switches guide the consignments into the corresponding transport lines and sorting compartments of the consignment sorting machines. The mail items are transported clamped in the transport strands between two transport belts of a shroud system. The transport belts are narrower than the items in height. In the case of corresponding known switches, the pivot bearing of a wedge-shaped guide element directed against the transport direction is located at the end of the switch area in the transport direction between the two inputs of the discharging shroud systems.
Depending on the swivel position, this guide element forms a channel for the mailings between its side wall in the respective outer continuous transport belt.
If the consignments run through the switch area, it is possible that, in particular, curved or kinked consignments will hit the pivot bearing and trigger a malfunction. In order to ensure that the sorting machine runs properly, the deflecting element must be in its respective end position before a shipment arrives in the switch. If the distances between the mail items are to be kept as small as possible for a high machine throughput, the deflection elements of the turnouts would have to switch over at a point in time at which the previous shipment has not yet left the turnout. In this case, however, this is only possible to a limited extent, since when the changeover is made at an early stage, the rear of the previous item is pressed against a conveyor belt, as a result of which the item can be destroyed or the switch cannot switch properly.

Die DE 4 317 042 C offenbart eine Weiche für flache, flexible Sendungen gemäß dem Oberbegriff von Anspruch 1.DE 4 317 042 C discloses a switch for flat, flexible shipments according to the preamble of claim 1.

Der im Anspruch 1 angegebenen Erfindung liegt die Aufgabe zugrunde, eine gattungsgemäße Weiche zu schaffen, die gegenüber bekannten Weichen geringere Störungsraten aufweist und kleinere minimale Abstände zwischen den Sendungen erlaubt.The invention specified in claim 1 is the Task to create a generic switch that has lower failure rates than known switches and smaller minimum distances between shipments allowed.

Durch die Verwendung der zwei miteinander fest verbundenen, starren Teilablenkelemente, zwischen denen die Sendungen geleitet werden, und die Anordnung der Schwenkachse seitlich außerhalb der im Weichenbereich auseinanderlaufenden Transportriemen am Beginn des Weichenbereiches in Transportrichtung gesehen, wird eine Berührung der Sendungen mit der Schwenkachse vermieden. Ein weiterer Vorteil besteht darin, daß auch bei sehr geringen Abständen zwischen den Sendungen und dem dadurch ggf. notwendigen Umschwenken des Ablenkelementes in die andere Abtransportrichtung, bevor die vorherigen Sendungen die Weiche verlassen haben, die vorherigen Sendungen mit dem hinteren Teil nicht mit den beschriebenen negativen Folgen gegen die Transportriemen gedrückt werden, sondern von den Transportriemen weg frei umgebogen werden.By using the two firmly connected, rigid partial deflection elements between which the items are directed be, and the arrangement of the pivot axis laterally outside the conveyor belts that diverge in the turnout area at the beginning of the turnout area in the direction of transport seen, a touch of the programs with the Avoided swivel axis. Another advantage is that even with very small intervals between the programs and the necessary pivoting of the deflection element in the other direction of transport before the previous ones Shipments that have left the switch, the previous shipments with the rear part not with the negative described Consequences are pressed against the conveyor belts, but can be freely bent away from the transport belt.

In einer vorteilhaften Ausbildung nach Anspruch 2 ist zur Aufwandsreduzierung die Achse einer Umlenkrolle, an der zu Beginn des Weichenbereiches die durchgehenden Transportriemen in die abzweigenden Richtungen umgelenkt werden, gleichzeitig die Schwenkachse des Ablenkelementes.In an advantageous embodiment according to claim 2 Reduction of effort the axis of a pulley on the The continuous conveyor belts begin at the turnout area be diverted in the branching directions at the same time the pivot axis of the deflecting element.

Nach Anspruch 3 ist es vorteilhaft, als Antrieb für das Ablenkelement einen steuerbaren Drehantrieb, z.B. einen Drehmagneten mit zwei einstellbaren Endlagen einzusetzen.According to claim 3, it is advantageous as a drive for the deflecting element a controllable rotary drive, e.g. a rotating magnet with two adjustable end positions.

Nachfolgend wird die Erfindung in einem Ausführungsbeispiel anhand der Zeichnung näher erläutert. The invention is described in an exemplary embodiment below explained in more detail with reference to the drawing.

In der Weiche gemäß FIG 1 werden Sendungen, die zwischen zwei Transportriemen 4,5 eingeklemmt antransportiert werden, auf zwei Richtungen verteilt. Dazu laufen die Transportriemen 4,5 an einer Umlenkrolle 6 auseinander und werden jeweils zu einer weiteren Umlenkrolle geleitet, über die ein Transportriemen geführt ist, so daß an diesen Rollen beginnend das Transportsystem mit zwei Transportriemen, zwischen denen eingeklemmt die Sendungen transportiert werden, weitergeführt wird. Die auseinanderlaufenden Transportriemen 4,5 müssen nicht zwangsläufig durchgehend sein, sie können auch über Rollen getrennt werden. Am Beginn des Weichenbereiches, annähernd auf der Höhe der Umlenkrolle 6, nur auf der anderen Seite der beiden Transportriemen 4,5 befindet sich die Schwenkachse 3 des Ablenkelementes. Dieses Ablenkelement besteht aus zwei starren Teilablenkelementen 1,2 die in Transportrichtung nebeneinander und annähernd parallel zueinander angeordnet sind. Sie sind außerhalb der Brieflaufebene, in diesem Fall unterhalb über eine Bodenplatte fest miteinander verbunden. Die Teil-ablenkelemente 1,2 sind nach rechts geschwenkt und leiten somit die Sendungen zwischen dem Teilablenkelement 1 und dem Transportriemen 4 in den rechten Transportpfad. Damit die Teilablenkelemente 1,2 die Schwenkbewegungen ausführen können, ohne dabei die Transportriemen 4,5 zu berühren, besitzen sie dafür notwendige Aussparungen, die in der Draufsicht nicht zu erkennen sind. In the switch according to FIG 1, shipments between two Transport belts 4.5 can be transported clamped on distributed in two directions. For this purpose, the transport belts 4.5 run apart on a pulley 6 and each become one another pulley passed over a conveyor belt is guided so that the transport system begins at these roles with two transport straps, clamped between them the shipments are transported, continued becomes. The diverging transport belts 4.5 must not necessarily be continuous, they can also be over Roles are separated. At the beginning of the turnout area, almost at the level of the pulley 6, only on the other The side of the two transport belts 4, 5 is located Pivot axis 3 of the deflecting element. This deflector is made from two rigid partial deflection elements 1, 2 in the direction of transport side by side and almost parallel to each other are arranged. You are outside the letter level, in in this case, firmly attached to each other below via a base plate connected. The partial deflection elements 1, 2 are pivoted to the right and thus direct the shipments between the partial deflection element 1 and the transport belt 4 in the right Transport path. So that the partial deflection elements 1, 2 the pivoting movements can run without losing the transport straps 4.5 touch, they have necessary recesses for this, that are not visible in the top view.

In der FIG 2 sind die Teilablenkelemente 1,2 nach links geschwenkt, so daß die Sendungen zwischen dem Transportriemen 5 und dem Teilablenkelement 2 in den linken Transportpfad geleitet werden. Wie zu erkennen, ist jeweils nur ein Teilablenkelement 1 oder 2 innerhalb des Sendungslaufbereiches, während sich das andere Teilablenkelement außerhalb befindet. Innerhalb des Sendungslaufbereiches sind keine Hindernisse vorhanden, da im Gegensatz zum Stand der Technik die Schwenkachse nicht im Sendungslaufbereich, sondern neben diesem angeordnet ist. Damit können insbesondere gebogene und geknickte Sendungen den Weichenbereich frei passieren. Sollen die Abstände zwischen den Sendungen möglichst gering sein, so muß die Weiche umgeschaltet werden, wenn die vorherige Sendung den Weichenbereich noch nicht vollständig verlassen hat. Dabei wird dann der hintere Teil der vorherigen Sendung in die andere Richtung umgebogen, ein störendes Drücken dieser Sendungen gegen die Transportriemen, wie bei der Darlegung des Standes der Technik beschrieben, tritt nicht auf.2, the partial deflection elements 1, 2 are pivoted to the left, so that the shipments between the conveyor belt 5th and the partial deflection element 2 in the left transport path become. As can be seen, there is only one partial deflection element 1 or 2 within the broadcasting area, while the other partial deflection element is outside. There are no obstacles within the program run area available because, in contrast to the prior art, the swivel axis not in the program run area, but next to it is. This allows in particular curved and kinked Consignments freely pass through the turnout area. Should they Distances between the shipments must be as small as possible the turnout can be switched when the previous broadcast has not yet completely left the turnout area. there the rear part of the previous program is then transferred to the bent another direction, a disturbing pressing of these programs against the conveyor belts, as in the presentation of the State of the art described does not occur.

In der FIG 3 ist die Weiche ohne Transportriemen perspektivisch dargestellt. Zur Vereinfachung wurden die Schwenkachse 3 der Teilablenkelemente 1,2 und die Drehachse der Umlenkrolle 6 zusammengefaßt. In dieser Darstellung sind auch die Aussparungen in den Teilablenkelementen 1,2 für die Transportriemen gut zu erkennen.In FIG 3 the switch is perspective without a conveyor belt shown. To simplify the swivel axis 3 of the partial deflection elements 1, 2 and the axis of rotation of the deflection roller 6 summarized. In this illustration, too the cutouts in the partial deflection elements 1, 2 for the Clearly recognizable transport straps.
