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.

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.The object is achieved by the features of claim 1 solved.

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.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 slope and increasing the number of spindle gears in the transport direction uniform loosening of the transported goods and alignment to the edge between the floor and the side boundary.

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. An inclination of the spindles in an advantageous lining of the invention according to claim 2 causes the flat objects better and Run more evenly into the spindles.  

In einem Beispiel wird die Erfindung nun anhand der Zeichnungen näher erläutert. Dabei zeigenIn an example, the invention will now be explained in more detail with reference to the drawings. Show

Fig. 1 eine schematische Perspektivdarstellung der erfindungsgemäßen Lösung zum Transport von Briefen und Karten zu einem Vereinzler einer Sortieranlage. 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 einen Querschnitt durch eine Spindel. Fig. 2 shows 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 from FIG. 1, there are two spindles SP in the base B with their longitudinal axes in the transport direction to the separator with its friction belt RB for pulling off the letters. Furthermore, there is also a spindle SP which is aligned in the same way in a vertical side delimitation SB which is attached laterally to the base B. These three spindles SP are identical in terms of diameter, pitch and number of gears and are at a height in the direction of transport. So that the letters and cards are aligned towards the edge between the floor and the side boundary, the spindles SP in the bottom have a right-hand turn, the spindle SP in the side border SB have a left-hand turn. The rotary movement of the spindles SP according to FIG. 1 aligns the letters on their rear and bottom edges, ie towards the edge between floor B and side boundary SB.

Dem Querschnitt durch eine Spindel 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 erfindungs­ gemäße Einrichtung ergibt.The cross section through a spindle SP according to FIG. 2 shows that the increase on the left at the inlet has the value S1 and increases continuously in the transport direction to a multiple value Sn. In addition, the spindle SP receives 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 fed to the separator, so that double deductions are reduced. In addition, the spindles SP are arranged obliquely so that they gradually rise at an angle from the floor B or the side limit SB in the transport direction, so that there is a uniform acceptance of the letters and cards in the device according to the Invention.
