Description

Die Erfindung bezieht sich auf eine Vorrichtung zum Zuführen und Auflockern von Stapeln flacher Gegenstände, insbesondere Postsendungen, zu einem Vereinzler einer Sortieranlage.The invention relates to a device for feeding and loosening Stacking flat objects, in particular mail items, to a separator a sorting system.

Bisher wurden Sendungsstapel von Briefen mittels Unterflurtransportband zugeführt und das Auflockern der Sendungsstapel erfolgte durch Einblasen von Luft. Ein Ausrichten der Einzelteile der Stapel wurde mithilfe von Rüttlern realisiert. Der Nachteil hierbei besteht in dem hohen Aufwand (3 Arbeitsschritte) und einer ungleichmäßigen Auflockerung, wodurch die Gefahren von Doppelabzügen beim anschließenden Vereinzeln der Briefe steigt. Die Auflockerung von Flats oder flachen Päckchen ist mittels Einblasen von Luft überhaupt nicht lösbar.So far, letters have been stacked using an underground conveyor belt fed and the loosening of the batch of mail was done by blowing in Air. Alignment of the individual parts of the stack was carried out with the help of vibrators. The disadvantage here is the high effort (3 work steps) and one uneven loosening, which increases the risk of double deductions when subsequent separation of the letters increases. The loosening up of flats or Flat packs cannot be detached at all by blowing in air.

Eine Vorrichtung zum Zuführen und Auflockern von Stapeln flacher Gegenstände zu einem Vereinzler einer Sortieranlage mit dem Merkmalen des Oberbegriffs von Anspruch 1 ist aus der US 4 884 795 A bekannt.A device for feeding and loosening stacks of flat objects to a separator of a sorting system with the features of the preamble of claim 1 is known from US Pat. No. 4,884,795.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zum ausgerichteten Zuführen und Auflockern von Sendungsstapeln flacher Gegenstände zu schaffen, die den Stand der Technik dahingehend verbessert, daß das Zuführen, Auflockern und Ausrichten in einem Arbeitsgang und die Auflockerung gleichmäßiger erfolgt, und daß auch Päckchen oder Flats aufgabengemäß zugeführt werden können.The invention has for its object a device for aligned Feeding and loosening batches of flat items, which improves the prior art in that feeding, loosening and alignment in one operation and the loosening takes place more evenly, and that packets or flats can also be fed in according to the task.

Die Aufgabe wird erfindungsgemäß durch die Merkmale des Patentanspruches 1 gelöst.
Der Vorteil dieser Lösung liegt darin, daß gleichzeitig mit der Transportbewegung, hervorgerufen durch die Drehung der Spindeln, durch die zunehmende Steigung und die Erhöhung der Anzahl der Spindelgänge in Transportrichtung eine gleichmäßige Auflockerung des Transportgutes und eine Ausrichtung zur Kante zwischen Boden und Seitenbegrenzung hin stattfindet.
Eine Schrägstellung der Spindeln in einer vorteilhaften Auskleidung der Erfindung gemäß Patentanspruch 2 bewirkt, daß die flachen Gegenstände besser und gleichmäßiger in die Spindeln einlaufen. The object is achieved by the features of claim 1.
The advantage of this solution is that at the same time as the transport movement, caused by the rotation of the spindles, by the increasing incline and the increase in the number of spindle paths in the transport direction, there is a uniform loosening of the transported goods and an alignment towards the edge between the floor and the side boundary.
An inclination of the spindles in an advantageous lining of the invention according to claim 2 causes the flat objects to run better and more evenly into the spindles.

In einem Beispiel wird die Erfindung nun anhand der Zeichnungen näher erläutert.

In an example, the invention will now be explained in more detail with reference to the drawings.
Show
Fig. 1
is a schematic perspective view of the solution according to the invention for the transport of letters and cards to a separator of a sorting system.
Fig. 2
a cross section through a spindle.

Wie der Fig. 1 zu entnehmen ist, befinden sich im Boden B zwei mit ihren Längsachsen in Transportrichtung zum Vereinzler mit seinem Reibband RB zum Abziehen der Briefe hin ausgerichtete Spindeln SP. Desweiteren befindet sich in einer senkrechten seitlich am Boden B angebrachten Seitenbegrenzung SB ebenfalls eine gleichausgerichtete Spindel SP. Diese drei Spindeln SP sind hinsichtlich Durchmesser, Steigung und Anzahl der Gänge gleich ausgeführt und liegen in Transportrichtung in einer Höhe. Damit die Briefe und Karten zur Kante zwischen Boden und Seitenbegrenzung hin ausgerichtet werden, haben die Spindeln SP im Boden eine rechtsgerichtete, die Spindel SP in der Seitenbegrenzung SB eine linksgerichtete Windung. Durch die Drehbewegung der Spindeln SP gemäß Fig. 1 werden die Briefe auf ihre Hinter- und Unterkante, d.h. zur Kante zwischen Boden B und Seitenbegrenzung SB hin, ausgerichtet.As can be seen in FIG. 1, there are two with their in bottom B. Longitudinal axes in the transport direction to the singler with its friction belt RB for Subtract the letters towards the spindles SP. Furthermore is located in a vertical side limit SB attached to the side of the floor B. also an SP spindle with the same orientation. These three spindles are SP with the same diameter, pitch and number of gears and are at a height in the direction of transport. So that the letters and cards to the edge between the floor and the side boundary have the Spindles SP in the bottom right-hand, the spindle SP in the Side boundary SB is a left turn. By rotating the Spindles SP according to Fig. 1, the letters on their rear and bottom edge, i.e. towards the edge between floor B and side limit SB, aligned.

Dem Querschnitt durch eine Spinel SP gemäß Fig. 2 kann man entnehmen, daß die Steigerung links beim Einlauf den Wert S1 hat und sich in Transportrichtung kontinuierlich auf einen mehrfachen Wert Sn erhöht. Zusätzlich erhält die Spindel SP ab ca. der Mitte der Längsrichtung einen zweiten Gang. Alle drei Spindeln SP sind bezüglich dieser Parameter gleich aufgebaut. Dadurch ergibt sich eine gleichmäßige Verringerung der Packungsdichte der zugeführten Briefe und Karten zum Vereinzler hin, so daß sich Doppelabzüge verringern. Zusätzlich sind die Spindeln SP so schräg angeordnet, daß sie sich allmählich unter einem Winkel aus dem Boden B bzw. der Seitenbegrenzung SB in Transportrichtung erheben, so daß sich eine gleichmäßige Übernahme der Briefe und Karten in die erfindungsgemäße Einrichtung ergibt.The cross section through a spinel SP according to FIG. 2 shows that the increase on the left at the inlet has the value S1 and in the direction of transport continuously increased to a multiple value Sn. In addition, the spindle receives SP a second gear from approx. The middle of the longitudinal direction. All three spindles SP have the same structure with regard to these parameters. This results in a uniform reduction in the packing density of the letters and cards supplied towards the singler, so that double deductions are reduced. In addition, they are Spindles SP are arranged so that they are gradually at an angle from floor B or the side limit SB in the direction of transport, see above that there is an even takeover of the letters and cards in the invention Establishment results.
