Abstract

The device has at least two spindles arranged in a base (B) which is aligned horizontally. It also has at least one spindle which is arranged in a side boundary (SB) which is aligned vertically. Each spindle (SP) has a straight core with its longitudinal axis aligned in the direction of transport of the flat objects, and all the spindles are driven at the same rotational speed. The objects are guided in the threads of the spindles, and lie on their cores. The pitch and number of threads increases in the transport direction, in the same manner on all the spindles. The direction of rotation and the helix direction of the spindles are arranged so that the objects are aligned during transportation towards the edge which is between the base and the side boundary.

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 stacks of flat objects, in particular mail items, to a separator of 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, mail stacks of letters have been fed using an underfloor conveyor belt, and the mail stacks have been loosened up 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 an uneven loosening, which increases the risk of double deductions when the letters are subsequently separated. The loosening of flats or flat packs cannot be solved 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 to provide a device for the aligned feeding and loosening of batches of flat items, which improves the state of the art in that the feeding, loosening and aligning in one operation and the loosening takes place more evenly, and that packages or Flats can be fed 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.
Dabei zeigen

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 from FIG. 1, there are two spindles SP in the base B with their longitudinal axes in the transport direction to the singler 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. Through the rotary movement of 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 increases continuously to a multiple value Sn in the transport direction. 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 boundary SB in the transport direction, so that there is a uniform transfer of the letters and cards into the device according to the invention.
