Abstract

In an apparatus for stamping flat objects of different sizes and thicknesses, particularly postal items, said objects are arranged vertically on a feed table. The objects are individually removed from the latter and successively moved past a stamp and are then conveyed to a depositing table. The supplied and deposited objects are in parallel planes to one another. The feed and depositing tables are successively arranged in a vertical direction to one of these planes. The objects are removed from the feed table at right angles to said direction and are supplied to the depositing table. The objects are placed on the feed table by their leading edge in the transfer direction during individual removal. The conveying path of the object between the feed and depositing tables is horizontal.

Description

Die Erfindung betrifft eine Einrichtung zum Stempeln von flachen Gegenständen unterschiedlicher Größe und Dicke, insbesondere Postgut, die auf einem Anlegetisch vertikal oder annähernd vertikal angeordnet, von diesem vereinzelt abgenommen, nacheinander an einem Stempel vorbeigeführt und zu einem Ablagetisch transportiert werden, wobei die angelegten und abgelegten Gegenstände in zueinander parallelen Ebenen angeordnet sind und die Gegenstände in Richtung dieser Ebenen vom Anlegetisch abgenommen und dem Ablagetisch zugeführt werden, daß die Gegenstände mit ihrer in Richtung des Transportes bei der vereinzelten Abnahme vorderen Kante auf dem Anlegetisch anlegbar sind und daß ihre Transportbahn zwischen dem Anlege- und dem Ablagetisch horizontal angeordnet ist.The invention relates to a device for stamping flat objects of different sizes and thicknesses, in particular postal items, which are arranged vertically or approximately vertically on a feed table, removed individually from the feed table, guided past a stamp in succession and transported to a storage table, the applied and deposited ones Objects are arranged in mutually parallel planes and the objects are removed in the direction of these planes from the feed table and fed to the storage table, that the objects can be placed on the feed table with their front edge in the direction of transport during the occasional removal, and that their transport path between the feeder - And the tray table is arranged horizontally.

Eine derartige Einrichtung ist aus der GB-A-9 031 bekannt. Die Vereinzelung der Gegenstände erfolgt hierbei mittels eines umlaufenden Bandes, gegen das die angelegten Gegenstände gedrückt werden. Anlege- und Ablagetisch liegen in Richtung der Ebenen der an- und abgelegten Gegenstände hintereinander. Der mit dem Band in Berührung stehende Gegenstand wird aufgrund der Reibungskräfte von diesem mitgenommen und durch einen Spalt geführt. Die Vereinzelung ist jedoch relativ problematisch, da die Kontaktfläche zwischen dem Band und dem anliegenden Gegenstand im Vergleich zur Kontaktfläche zwischen den einzelnen Gegenständen klein ist. So kann es passieren, daß entweder das Band am anliegenden Gegenstand entlangrutscht, ohne diesen mitzunehmen, oder daß zwei oder noch mehr Gegenstände gleichzeitig mitgenommen und durch den Spalt transportiert werden. Weiterhin kann es möglich sein, daß die Einrichtung nicht die geforderte Kompaktheit besitzt.Such a device is known from GB-A-9 031. The objects are separated by means of a circulating belt against which the objects are pressed. The lay-on and lay-down table lie one behind the other in the direction of the levels of the put on and put down objects. The object in contact with the belt is carried along by the frictional forces and guided through a gap. However, the separation is relatively problematic, since the contact area between the belt and the adjacent object is small compared to the contact area between the individual objects. It can happen that either the belt slides along the adjacent object without taking it along, or that two or more objects are taken along at the same time and transported through the gap. Furthermore, it may be possible that the device does not have the required compactness.

Es ist daher die Aufgabe der vorliegenden Erfindung, die vorgenannte Einrichtung in der Weise zu verbessern, daß die Zuverlässigkeit der Vereinzelung ohne Vergrößerung der aufzuwendenden Kräfte erhöht wird. Auch soll diese Einrichtung möglichst kompakt ausgebildet sein.It is therefore the object of the present invention to improve the aforementioned device in such a way that the reliability of the separation is increased without increasing the forces to be applied. This device should also be as compact as possible.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Anlege- und der Ablagetisch in der zu den Ebenen der. angelegten und abgelegten Gegenstände senkrechten Richtung hintereinander angeordnet sind, und daß zum vereinzelten Abnehmen der Gegenstände eine pneumatische Trennvorrichtung vorgesehen ist, die ein umlaufendes Lochband zur Mitnahme des jeweils ersten Gegenstandes auf dem Anlegetisch durch Unterdruck sowie einen gegenüberliegenden pneumatischen Gegenhalter zum Festhalten des jeweils zweiten Gegenstandes auf dem Anlegetisch durch Unterdruck aufweist.This object is achieved in that the feed and storage table in the to the levels of. applied and stored objects are arranged in the vertical direction one behind the other, and that for the individual removal of the objects a pneumatic separating device is provided which has a circumferential perforated band for taking the first object on the feed table by negative pressure and an opposite pneumatic counter holder for holding the second object has the feed table by negative pressure.

Vorteilhafte Weiterbildungen der erfindungsgemäßen Einrichtung ergeben sich aus den Unteransprüchen.Advantageous further developments of the device according to the invention result from the subclaims.

Die Erfindung wird im folgenden anhand eines in der Figur dargestellten Ausführungsbeispiels näher erläutert. Diese zeigt eine Einrichtung zum Stempeln von flachen Gegenständen, insbesondere Postgut unterschiedlicher Größe und Dicke in der Draufsicht.The invention is explained below with reference to an embodiment shown in the figure. This shows a device for stamping flat objects, in particular mail items of different sizes and thicknesses, in a top view.

Die zu stempelnden Gegenstände 1 werden auf einem Anlegetisch 2 gestapelt. Hierbei sind die Gegenstände 1 senkrecht angeordnet und liegen mit einer Kante an einer Anschlagleiste 3 an. Die Gegenstände 1 befinden sich auf einem Anlage-Transportband 4 und werden durch ein Anlage-Stapelblech 5 in ihrer senkrechten Lage gehalten. Das Stapelblech 5 ist an einem auf der Anschlagleiste 3 verschiebbaren Gelenk 6 befestigt. Das Anlage-Stapelblech liegt mit seinem Eigengewicht auf dem Transportband 4 und wird von diesem stets gegen die auf dem Anlegetisch 2 befindlichen Gegenstände 1 gedrückt. Das Transportband 4 ist in der durch den Pfeil gekennzeichneten Richtung bewegbar. Die Bewegung des Transportbandes 4 wird durch einen nicht dargestellten Schalter gesteuert, der sich im Bereich einer pneumatischen Trennvorrichtung 7 befindet und die Anlage der Gegenstände 1 an der Trennvorrichtung 7 feststellt.The objects 1 to be stamped are stacked on a feed table 2. Here, the objects 1 are arranged vertically and rest with an edge on a stop bar 3. The objects 1 are located on a system conveyor belt 4 and are held in their vertical position by a system stacking plate 5. The stacking plate 5 is fastened to a joint 6 which can be displaced on the stop bar 3. The system stacking plate lies with its own weight on the conveyor belt 4 and is always pressed by this against the objects 1 located on the feed table 2. The conveyor belt 4 can be moved in the direction indicated by the arrow. The movement of the conveyor belt 4 is controlled by a switch, not shown, which is located in the area of a pneumatic separating device 7 and detects that the objects 1 abut on the separating device 7.

Die Trennvorrichtung 7 weist ein umlaufendes Lochband 8 auf, durch welches hindurch ein Unterdruck auf den jeweils vordersten der gestapelten Gegenstände 1 ausgeübt wird. Das Lochband 8 läuft im Uhrzeigersinn um und nimmt dabei den angesaugten vordersten Gegenstand 1 mit. Ein dem Lochband 8 gegenüberliegender pneumatischer Gegenhalter 9 hält den hinter dem ersten Gegenstand angeordneten zweiten Gegenstand fest, falls dieser infolge von Reibung von dem ersten Gegenstand mitgenommen werden sollte. Der Gegenhalter 9 arbeitet ebenfalls mit Unterdruck, wobei dieser jedoch geringer ist als der durch das Lochband 8 auf den ersten Gegenstand wirkende Unterdruck.The separating device 7 has a circumferential perforated band 8, through which a negative pressure is exerted on the foremost of the stacked objects 1. The perforated tape 8 runs in a clockwise direction and takes the suctioned foremost object 1 with it. A pneumatic counter-holder 9 opposite the perforated band 8 holds the second object arranged behind the first object in case it should be taken along by the first object due to friction. The counter holder 9 also works with negative pressure, but this is less than the negative pressure acting on the first object through the perforated band 8.

Die auf die beschriebene Weise vereinzelten Gegenstände 1 werden in den Zwischenraum zwischen zwei umlaufenden Transportbändern 10 und 11 geführt und zwischen diesen in Pfeilrichtung mitgenommen.The objects 1 separated in the manner described are guided into the space between two circulating conveyor belts 10 and 11 and are carried along between them in the direction of the arrow.

Die Geschwindigkeit der Transportbänder 10 und 11 ist größer als diejenige des Lochbandes 8. Hierdurch werden die zwischen die Transportbänder 10 und 11 geführten Gegenstände schneller weggezogen als der jeweils vom Lochband gelieferte nachfolgende Gegenstand. Hierdurch entsteht ein Zwischenraum zwischen den einzelnen Gegenständen, der ausreicht, um diese jeweils einzeln feststellen zu können.The speed of the conveyor belts 10 and 11 is greater than that of the perforated belt 8. As a result, the objects guided between the conveyor belts 10 and 11 are pulled away faster than the subsequent object delivered by the perforated belt. This creates a space between the individual objects that is sufficient to be able to identify them individually.

Die vereinzelten und zwischen den Transportbändern 10 und 11 beförderten Gegenstände werden von einer Lichtschranke 12 erfaßt. Diese löst bei der Feststellung der Vorderkante eines Gegenstandes jeweils eine Umdrehung eines im Transportweg der Gegenstände nachfolgenden Stempels 13 aus. Der Stempel ist auswechselbar auf einer kernverzahnten Stempelwelle befestigt. Eine weitere Lichtschranke 14 dient zur jeweiligen Positionierung des Stempels 13 in der Grundstellung zwischen zwei Stempeivorgängen.The isolated and transported between the conveyor belts 10 and 11 objects are detected by a light barrier 12. When the front edge of an object is ascertained, this triggers one revolution of a stamp 13 following in the transport path of the objects. The stamp is exchangeably attached to a core-toothed stamp shaft. Another light barrier 14 is used for each Positioning of the stamp 13 in the basic position between two stamping processes.

Der von den Transportbändern 10 und 11 freigegebene Gegenstand 1 wird dem Spalt zwischen dem Stempel 13 und einer Gegendruckwalze 15 zugeführt. Die federnd gelagerte, angetriebene Gegendruckwalze sorgt für kräftige und gleichmäßige Stempelabdrücke. Durch eine Verstellvorrichtung 16 kann der Zwischenraum zwischen dem Stempel 13 und der Gegendruckwalze 15 voreingestellt werden. Dies ist vorteilhaft bei der Stempelung von annähernd gleich dicken Gegenständen 1. Auf diese Weise können dauernde und schlagartige Bewegungen der Gegendruckwalze vermieden werden.The object 1 released by the conveyor belts 10 and 11 is fed to the gap between the stamp 13 and a counter-pressure roller 15. The spring-loaded, driven counter-pressure roller ensures strong and even stamp impressions. The gap between the punch 13 and the counter-pressure roller 15 can be preset by an adjusting device 16. This is advantageous when stamping objects 1 of approximately the same thickness. In this way, permanent and sudden movements of the counter-pressure roller can be avoided.

Die Gegendruckwalze 15 ist weiterhin über ein Gelenk 17 mit einer beweglich gelagerten Rolle 18 verbunden, die zur Führung des Transportbandes 10 dient und am Ausgang des von den Transportbändern 10 und 11 gebildeten Schlitzes angeordnet ist. Durch diese Gelenkverbindung zwischen der Rolle 18 und der Gegendruckwalze 15 wird diese vor dem Eintreffen eines Gegenstandes am Stempel 13 bereits auf dessen Dicke voreingestellt. Hierdurch werden auch bei Gegenständen unterschiedlicher Dicke stets gleichmäßige Stempelabdrücke erzielt.The counter-pressure roller 15 is further connected via a joint 17 to a movably mounted roller 18 which serves to guide the conveyor belt 10 and is arranged at the exit of the slot formed by the conveyor belts 10 and 11. By means of this articulated connection between the roller 18 and the counter-pressure roller 15, this is already preset to its thickness before the arrival of an object on the stamp 13. As a result, even stamp impressions are always achieved even with objects of different thickness.

Ein Farbwerk 19 mit einer mit Stempelfarbe getränkten Filzwalze und einer angetriebenen Zwischenwalze dient zur gleichmäßigen Einfärbung des Stempels 13 bei jeder Umdrehung desselben.An inking unit 19 with a felt roller impregnated with stamp ink and a driven intermediate roller serves for the uniform inking of the stamp 13 with each revolution of the same.

Nach dem Passieren des Stempels 13 werden die Gegenstände 1 von einem weiteren Transportband 20 übernommen und zu einem Ablagetisch 21 befördert. Dieser Transport erfolgt zusätzlich mit Hilfe eines Leitblechs 22 mit Führungsrolle und einer Stützrolle 23 mit Mitnahmeteller.After passing the stamp 13, the objects 1 are taken over by a further conveyor belt 20 and conveyed to a storage table 21. This transport is also carried out with the aid of a guide plate 22 with a guide roller and a support roller 23 with a driving plate.

Der Ablagetisch 21 ist im wesentlichen in gleicher Weise aufgebaut wie der Anlegetisch 2. Die eintreffenden Gegenstände werden zunächst von einem Anschlagwinkel mit Abstreifer 24 vom Transportband 20 getrennt. Die gestapelten Gegenstände werden von einem Ablage-Transportband 25 in Pfeilrichtung befördert. Ein in gleicher Weise wie das Stapelblech 5 verschiebbares Ablage-Stapelblech 26 wird durch ein Gegengewicht gegen die gestapelten Gegenstände 1 gedrückt, so daß diese ihre senkrechte Lage behalten. Diese können manuell vom Ablagetisch heruntergenommen werden, wobei das Stapelblech 26 anschließend selbsttätig nach links bewegt wird, bis es auf die neu abgelegten Gegenstände trifft.The storage table 21 is constructed essentially in the same way as the feed table 2. The arriving objects are first separated from the conveyor belt 20 by a stop bracket with a scraper 24. The stacked objects are conveyed by a storage conveyor 25 in the direction of the arrow. A stackable stacking plate 26 which can be displaced in the same way as the stacking plate 5 is pressed by a counterweight against the stacked objects 1, so that they keep their vertical position. These can be manually removed from the storage table, the stacking plate 26 then being moved automatically to the left until it hits the newly placed objects.

Durch die Anlage der Vorderkanten der Gegenstände 1 an der Anschlagleiste 3 ist sichergestellt, daß jeweils nur der vorderste Gegenstand mit dem Lochband 8 der pneumatischen Trennvorrichtung 7 in Berührung gelangt. Es ist daher eine zuverlässige Vereinzelung möglich. Dadurch, daß die Gegenstände von der Trennvorrichtung 7 nur horizontal zu den Transportbändem 10 und 11 verschoben werden, kann die auf die Gegenstände wirkende Saugkraft relativ gering gehalten werden.The contact of the front edges of the objects 1 with the stop bar 3 ensures that only the foremost object comes into contact with the perforated band 8 of the pneumatic separating device 7. Reliable separation is therefore possible. Because the objects are only moved horizontally from the separating device 7 to the conveyor belts 10 and 11, the suction force acting on the objects can be kept relatively low.
