Description

Die vorliegende Erfindung betrifft eine Vorrichtung zur Bearbeitung von gestapeltem Flachgut, insbesondere von Briefen, wobei die Vorrichtung eine ein Magazin bildende Aufgabestation aufweist, der das Flachgut in einem Stapel zugeführt wird, wobei die Aufgabestation ein Gegenlager aufweist, an dem das Flachgut mit einer Stoßseite anliegt und wobei in Förderrichtung hinter der Aufgabestation eine Einrichtung zum Vereinzeln des in dem Stapel zugeführten Flachgutes angeordnet ist.The present invention relates to a device for processing stacked flat material, in particular of letters, wherein the device has a magazine forming a feed station, the flat material is fed in a stack, wherein the feed station has an abutment against which the flat material with a collision side and wherein in the conveying direction behind the feeding station means for separating the flat material supplied in the stack is arranged.

Es sind Anlagen bekannt, die zur Großbriefsortierung eingesetzt werden. Diese haben eine Aufgabestation ("Stoffeingaben" oder "Feeder"), welche die Briefe in stehenden Stapeln aufnimmt, wobei zwei Stapel durch Schwerter getrennt sind. Die Briefe stehen mit ihren Stoßseiten auf einem ein Gegenlager bildendes Unterflurband auf, das sie in senkrechter Richtung zu ihrer Flachseite fördert, wobei die Schwerter mitgeführt werden. Die einzelnen Briefe erreichen so das Ende der Förderstrecke, an dem eine zur Stoßseite parallele Abrutschkante vorgesehen ist, von der sie der Reihe nach abrutschen und mit der Stoßseite (Orientierungskante) auf eine weitere mit Kegelrollen ausgerüstete Förderstrecke aufsetzen. Auf dieser Förderstrecke werden sie in senkrechter Richtung zur Förderrichtung des Feeders mit hoher Geschwindigkeit abgezogen und auf diese Weise vereinzelt. Diese Vereinzelung wird durch die Kegelrollen unterstützt, deren unterschiedlicher Radius zu einem Gradienten in der Fördergeschwindigkeit der einzelnen Briefe führt.There are facilities known that are used for large letter sorting. These have a feed station ("fabric feeders" or "feeders") which receives the letters in standing stacks, with two stacks separated by swords. The letters stand with their abutment sides on an abutment-forming underfloor belt, which promotes them in the direction perpendicular to their flat side, with the swords are carried. The individual letters thus reach the end of the conveying path at which a slide-off edge parallel to the abutment side is provided, from which they slide off one after the other and place with the abutting side (orientation edge) on a further conveyor track equipped with tapered rollers. On this conveyor line they are withdrawn in a vertical direction to the conveying direction of the feeder at high speed and on this Way isolated. This separation is supported by the tapered rollers whose different radius leads to a gradient in the conveying speed of the individual letters.

Problematisch an den bislang bekannten Anlagen ist allerdings, dass in dem Stapel mitunter nicht alle Briefe bündig auf dem Unterflurband stehen, weil die Bündigung bei der manuellen Eingabe nicht vollständig war oder weil es zu einem Verhaken von Falzkanten kommt. Dieses Problem tritt insbesondere bei der Verarbeitung gemischtformatiger Großbriefen unterschiedlicher Stärken auf. Diese schräge Orientierung setzt sich bei der weiteren Bearbeitung fort, da diese Briefe sich auch nach dem Abrutschen vom Unterflurband nicht auf ihre Stoßkante stellen können, wenn ihnen der entsprechende Freilauf fehlt. Die Schrägstellung bleibt daher bei der weiteren Bearbeitung erhalten, wenn den Briefen keine Möglichkeit gegeben wird, sich auf der weiteren Strecke zu setzen.The problem with the previously known systems, however, is that in the stack sometimes not all letters are flush on the underfloor belt, because the blending was not complete in the manual input or because it comes to a hooking of folded edges. This problem occurs in particular when processing mixed-format large letters of different strengths. This oblique orientation continues in the further processing, since these letters can not stand on their edge even after slipping off the underfloor belt, if they lack the corresponding freewheel. The inclination is therefore retained in the further processing, if the letters are given no opportunity to sit on the further route.

Letztendlich werden dann die Briefe zum maschinellen Lesen der Adresse auf ihre Flachseite gekippt, wobei eine definierte Orientierung Voraussetzung für einen erfolgreichen Lesevorgang ist. Die anfänglich schräg aufstehenden Briefe erfüllen diese Voraussetzung jedoch nicht und müssen aus dem Prozess aussortiert und ihm nunmehr korrekt gebündigt wieder zugeführt werden. Diese "Extrarunde" geht mit überflüssigem Zeitaufwand und daher mit unnötigen Kosten einher.Finally, the letters are then tipped to machine-read the address on their flat side, with a defined orientation is a prerequisite for a successful read. However, the initial obliquely upstanding letters do not meet this requirement and must be sorted out of the process and fed back to him now properly terminated. This "extra round" involves a waste of time and therefore unnecessary costs.

Aufgabe der Erfindung ist es nunmehr, eine Einrichtung zu schaffen, die sich mit einfachen Mitteln kostengünstig umsetzen lässt und die eine im Hinblick auf eine definierte Orientierung optimierte Aufgabe der Flachstücke ermöglicht.The object of the invention is now to provide a device that can be implemented inexpensively by simple means and which allows optimized in terms of a defined orientation task of the sheets.

Diese Aufgabe wird durch die Vorrichtung nach Anspruch 1 gelöst.This object is achieved by the device according to claim 1.

Danach liegt der Grundgedanke der Erfindung darin, das Flachgut einmal auf zu rütteln, während es innerhalb der Aufgabestation im Stapel noch relativ locker zusammensteht. Erfindungsgemäß wird dazu das Gegenlager oder zumindest ein Teil des Gegenlagers, an dem das Flachgut mit einer Stoßseite anliegt, in Verbindung mit einem Rüttelmittel gebracht, welches das Teil des Gegenlagers zumindest zeitweise in Schwingungen versetzt. Die Schwingungen sind dabei in ihrer Frequenz und ihrer Amplitude so bemessen, dass sie ein Bündigen des Flachgutes bezüglich der Stoßseite bewirken. Das Gegenlager bildet dabei einen Teil des Magazintisches.Thereafter, the basic idea of the invention is to shake the flat material once while it still stands together relatively loosely within the feed station in the stack. According to the invention, the abutment or at least a part of the abutment on which the flat material bears with a abutment side is brought into connection with a shaking means, which at least temporarily causes the part of the abutment to vibrate. The vibrations are in their frequency and their amplitude are such that they effect a flattening of the flat material with respect to the abutting side. The anvil forms a part of the magazine table.

Mit diesem Rütteln wird eine erhebliche Verbesserung der Zuführungsqualität der Briefsendungen vom bestehenden Magazin in das Vereinzelungsmodul erreicht. Die Vorteile des Rüttelns betreffen insbesondere Sendungen, die als gemischtes Format, von zum Beispiel C6 bis B4 in unterschiedlicher Dicke von 0,5 bis 20mm und mit unterschiedlichen Umschlagsarten, in das System eingegeben werden. Wie schon angedeutet, können gerade diese Sendungen zu Störungen des Betriebes führen, wenn sie nicht unterkantenbündig auf dem transportierenden Unterflurband aufsitzen. Das Rütteln bewirkt nunmehr, dass die Sendungen sich unterkantenbündig ausrichten und so in den folgenden Verarbeitungsschritten zu einer deutlich verringerten Störanfälligkeit führen.With this shaking, a significant improvement in the delivery quality of the letter mail from the existing magazine to the singulation module is achieved. The advantages of jogging are in particular shipments which are entered into the system as a mixed format of, for example, C6 to B4 in different thicknesses of 0.5 to 20 mm and with different types of transhipment. As already indicated, it is precisely these transmissions that can lead to disruptions of the operation if they are not seated on the transporting underfloor belt at the bottom edge. The shaking now causes the programs align themselves flush with the edge and thus lead in the following processing steps to a significantly reduced susceptibility to interference.

Besonders einfach ist der "Rüttler" zu realisieren, wenn er den entsprechenden Teil des Gegenlagers lediglich in eine vertikale Schwingung versetzt. Zu diesem Zwecke kann das Rüttelmittel von einem Elektromotor gebildet werden, auf dessen Welle ein Excenter aufsitzt. Dieser wird über eine Stange direkt oder indirekt mit dem schwingungsfähigen Teil des Gegenlagers verbunden. Der Hub der Schwingung wird über den Excenter eingestellt, während sich die Frequenz über die Motordrehzahl variabel steuern lässt. Um eine möglichst effektive Bündigung zu erreichen, ist es vorteilhaft, neben der vertikalen Komponente der Schwingung zusätzlich eine horizontale Komponente vorzusehen. Diese bewirkt dann eine weitere Trennung der zusammenhängenden Einzelstücke.It is particularly easy to realize the "jogger" when he just puts the corresponding part of the thrust bearing in a vertical vibration. For this purpose, the shaking means can be formed by an electric motor, on whose shaft an eccentric is seated. This is connected via a rod directly or indirectly to the oscillatory part of the anvil. The stroke of the vibration is adjusted via the eccentric, while the frequency can be variably controlled by the engine speed. In order to achieve the most effective possible bundling, it is advantageous to additionally provide a horizontal component in addition to the vertical component of the vibration. This then causes a further separation of the coherent individual pieces.

Eine weitere Effizienz der Bündigung kann erreicht werden, indem die Amplitude und/oder die Frequenz und/oder die Richtung der vom Rüttelmittel erzeugten Schwingungen während des Rüttelns veränderlich ist. Das kann dadurch erzeugt werden, dass der Grundschwingung eine weitere Schwingung überlagert wird, so dass es zu einer Schwebung kommt. Gerade der mit einer Kraftbeaufschlagung aus verschiedenen Richtungen gepaarte Frequenzwechsel kann eine hartnäckige Verbindung zwischen zwei Einzelstücken lösen.Further efficiency of the fusion can be achieved by varying the amplitude and / or the frequency and / or the direction of the vibrations generated by the shaker during the shaking. This can be produced by superimposing another oscillation on the fundamental, so that a beating occurs. Especially with a force application from different directions paired frequency change can solve a persistent connection between two individual pieces.

Technisch lässt sich der Rüttler besonders einfach und kostengünstig aufbauen, wenn der mit dem Rüttelmittel verbundene Teil des Gegenlagers von einer relativ schmalen und leichten Auflageplatte gebildet wird, auf der die in dem Stapel vereinten flachen Einzelstücke mit der Stoßseite aufstehen. Diese Auflageplatte mit relativ geringer Trägheit kann dann von einem verhältnismäßig schwachen Rüttelmittel angetrieben werden.Technically, the vibrator can be particularly simple and inexpensive to build when the part of the thrust bearing connected to the Rüttelmittel is formed by a relatively narrow and lightweight support plate on which the united in the stack flat individual pieces with the butt side up. This support plate with relatively low inertia can then be driven by a relatively weak Rüttelmittel.

Diese Auflageplatte bildet idealerweise den Abschluss der Transportstrecke und damit die Abrutschkante. Diese unmittelbar mit dem Rüttelmittel verbundene Abrutschkante führt zu einer besonders effizienten Trennung. Die Einzelstücke werden insbesondere von einem Unterflurband auf die Auflageplatte transportiert, von deren Kante sie dann auf die weitere Förderstrecke abrutschen. In dieser Position am Ende der Transportstrecke lockert die gegenseitige Klemmung der Einzelstücke auf, so dass das Rütteln zu einem effizienten Aufsetzen auf der Orientierungskante führen kann. Ein weiterer Vorteil dieser Ausführungsform liegt darin, dass sie technisch insofern einfach zu realisieren ist, als sich ein solcher Rüttler als separates Bauteil zwischen zwei Transportbänder bauen lässt. Daher können sogar bestehende Anlagen mit einem solchen Rüttler nachgerüstet werden. Zur weiteren Unterstützung der Bündigung ist es vorteilhaft, wenn die am Ende der Förderstrecke angebrachte Auflageplatte in Förderrichtung schräg nach unten geneigt ist, so dass das Abrutschen unterstützt wird.This support plate ideally forms the conclusion of the transport route and thus the slip-off edge. This slip-off edge connected directly to the shaking means leads to a particularly efficient separation. The individual pieces are transported, in particular, from an underfloor belt to the support plate, from the edge of which they then slide onto the further conveying path. In this position at the end of the transport path, the mutual clamping of the individual pieces loosens, so that the shaking can lead to an efficient placement on the orientation edge. Another advantage of this embodiment is that it is technically easy to implement insofar as such a vibrator can be built as a separate component between two conveyor belts. Therefore, even existing systems can be retrofitted with such a vibrator. To further support the bundling, it is advantageous if the support plate attached to the end of the conveyor line is inclined in the conveying direction obliquely downwards, so that the slipping is supported.

Der Verfahrensablauf lässt sich folgendermaßen zusammenfassen: Zu Beginn der Verarbeitung entnehmen Bedienkräfte die Einzelstücke (Sendungen) aus den Briefbehältern und setzten sie möglichst bündig auf dem Magazintisch auf. Die Sendungen werden dann mittels der zwei den Stapel auf seinen Flachseiten bedeckenden Schwerter und des Unterflurantriebs in Richtung der Vorrichtung zur Vereinzelung transportiert. Vor der Übergabe der Sendungen vom Magazintisch auf die Kegelrollen überfahren die Sendungen den erfindungsgemäßen Rüttler, der eine nahezu vollständige Bündigung bewerkstelligt. Durch den Vortrieb und durch die Konusform der Kegelrollen werden die abgerutschten Sendungen weiter aufgefächert. Nach einer Auffächerstrecke, die vorteilhafterweise länger als 400 mm ist, werden die Sendungen einer Reibvereinzelung zugeführt. Diese entnimmt immer den ersten Brief und führt ihn dem weiteren Verarbeitungssystem zu.The procedure can be summarized as follows: At the beginning of processing, operators remove the individual items (consignments) from the letter containers and place them as flush as possible on the magazine table. The consignments are then transported by means of the two swords covering the stack on its flat sides and the underfloor drive in the direction of the device for singling. Before the handover of the items from the magazine table to the tapered rollers, the items pass over the vibrator according to the invention, which accomplishes an almost complete rounding. Through the propulsion and the cone shape of the tapered rollers slipped shipments are further fanned. After a fan spread, which is advantageously longer than 400 mm, the items are fed to a Reibzellzelung. This always takes the first letter and feeds it to the other processing system.

Wurden jedoch bei dem Aufbringen des Briefgutes auf das Magazin nicht alle Sendungen mit ihrer Unterkante auf den Unterflurantrieb ausgerichtet, ergibt sich das oben beschriebene Problem beim Vereinzeln an der Reibvereinzelung. Die zu hoch stehenden Sendungen werden von den Reibriemen während des Abzugs schräg gezogen und verursachen durch ihre undefinierte Position eine erhebliche Anzahl von Brieflaufstörungen. Dieser schon beschriebene Nachteil ist durch den erfindungsgemäßen Rüttler, der vorteilhafterweise an der Übergangsstelle vom Magazintisch zu den Kegelrollen eingebaut ist, behoben. Wie dargelegt, bewirkt dieser Rüttler, dass die Sendungen, die nicht mit ihrer Unterkante auf dem Unterflurband des Magazins aufsitzen, durch die Vibration nach unten rutschen und dadurch problemlos an der Reibvereinzelung verarbeitet werden können.If, however, not all mail items were aligned with their lower edge on the underfloor drive during the application of the mail piece to the magazine, the above-described problem results when singulating on the friction separation. The items that are too high are pulled diagonally by the friction belts during the deduction and, due to their undefined position, cause a considerable number of letter disturbances. This disadvantage already described is eliminated by the vibrator according to the invention, which is advantageously installed at the transition point from the magazine table to the tapered rollers. As stated, this vibrator causes the programs that do not rest with their lower edge on the bottom edge of the magazine slide down by the vibration and thus can be easily processed at the Reibparzelung.

In Figur 1 ist Vorrichtung zur Bearbeitung von gestapelten Briefen 1 gezeigt, die eine ein Magazin bildende Aufgabestation 2 aufweist. Diese hier nur schematisch gezeigte Aufgabestation 2 hat eine starre Bodenplatte 3, auf die die Stapel mit Hand aufgesetzt werden. Die Bodenplatte 3 bildet ein Gegenlager, an dem das Flachgut (hier Briefe) mit einer Stoßseite anliegt. Mitunter sind die Briefe nicht bündig, sondern stehen, wie hier der Brief 4, wegen eines Verhakens etwas aus dem Stapel vor.FIG. 1 shows a device for processing stacked letters 1, which has a loading station 2 forming a magazine. This loading station 2 shown here only schematically has a rigid bottom plate 3, on which the stacks are placed by hand. The bottom plate 3 forms an abutment on which the flat material (here letters) rests with a collision side. Sometimes the letters are not flush, but are, as here the letter 4, because of a Verhakens something from the stack.

Der Stapel wird durch ein als Unterflurband 5 ausgeführtes Transportband einer Einrichtung 6 zum Vereinzeln zugeführt (Pfeil B), von der in diesem Fall im wesentlichen eine Laufstrecke mit einzeln angetriebenen Kegelrollen 7 gezeigt ist. Über diese Kegelrollen 7 werden die darauf aufsitzenden Briefe in Richtung des Pfeiles A abtransportiert.The stack is supplied by a conveyor belt designed as underfloor belt 5 means 6 for dicing (arrow B), of which in this case in essentially a running track with individually driven tapered rollers 7 is shown. About this tapered rollers 7, the seated letters are transported away in the direction of arrow A.

Das Gegenlager 3 weist eine Auflageplatte 8 auf, der die in dem Stapel vereinten Briefe 1 zugeführt werden und auf der sie letztendlich mit der Stoßseite aufstehen. Diese beweglich gelagerte Auflageplatte 8 ist über ein Gestänge 9 mit einem Rüttelmittel verbunden. Das Rüttelmittel wird hier von einem Motor 10 gebildet, auf dessen Welle ein Excenter aufsitzt, wobei das Gestänge 9 an den Excenter koppelt. Der so realisierte Rüttler verursacht eine Vibration der Auflageplatte 8, wobei die Vibration ein Bündigen des Flachgutes bezüglich der Stoßseite bewirkt.The anvil 3 has a support plate 8, which are fed to the letters united in the stack 1 and on which they finally stand up with the abutting side. This movably mounted support plate 8 is connected via a linkage 9 with a Rüttelmittel. The Rüttelmittel is here formed by a motor 10, on the shaft of an eccentric is seated, wherein the linkage 9 coupled to the eccentric. The thus realized vibrator causes a vibration of the support plate 8, wherein the vibration causes a flattening of the flat material with respect to the abutting side.

Wie in Figur 2 gezeigt, ist die Auflageplatte 8 in Förderrichtung um einem kleinen Winkel nach unten geneigt, der den Übergang der Briefe 11 auf die Kegelrollen 12 unterstützt. An ihrem Ende bildet die Auflageplatte 8 eine Abrutschkante 13 aus, von der die Briefe 11 in nahezu homogener Bewegung auf die Kegelrollen 12 rutschen. Gegen vorzeitiges unkontrolliertes Abrutschen wird der erste Brief 11 von einem Sensor in Richtung Pfeil C beaufschlagt. Die von der Abrutschkante gerutschten Briefe treffen auf der unteren Kante stehend auf die Kegelrollen 12 auf und werden parallel zur unteren Kante transportiert.As shown in Figure 2, the support plate 8 is inclined in the conveying direction by a small angle downwards, which supports the transition of the letters 11 on the tapered rollers 12. At its end, the support plate 8 forms a slip-off edge 13 from which the letters 11 slide in almost homogeneous motion on the tapered rollers 12. Against premature uncontrolled slipping the first letter 11 is acted upon by a sensor in the direction of arrow C. The slipped from the slip edge letters meet on the lower edge standing on the tapered rollers 12 and are transported parallel to the lower edge.

Die Auflageplatte 8 ist Teil des Rüttlers, der als zentrales Bauteil den Motor 10 aufweist. Der Motor 10 hängt an einer Halterung 14, die starr mit dem Gegenlager 3 verbunden ist. Über Gummipuffer 15 koppelt eine Basisplatte 16 an die Halterung 14, wobei auf der Basisplatte 16 ein in seiner Höhe einstellbarer Sockel 17 angebracht ist, der die Auflageplatte 8 trägt. Die Basisplatte 16 und damit die Auflageplatte 8 wird über einen Excenter vom Motor 10 in Vibration versetzt, wobei die Gummipuffer 15 die Vibration erlauben.The support plate 8 is part of the vibrator, which has the motor 10 as a central component. The motor 10 hangs on a bracket 14 which is rigidly connected to the anvil 3. Via rubber buffer 15, a base plate 16 couples to the holder 14, wherein on the base plate 16, a height-adjustable base 17 is mounted, which carries the support plate 8. The base plate 16 and thus the support plate 8 is set in vibration via an eccentric from the motor 10, wherein the rubber buffer 15 allow the vibration.
