Description

Die vorliegende Erfindung betrifft eine Vorrichtung zum Vereinzeln von flachen Sendungen nach dem Oberbegriff des Patentanspruchs 1.The present invention relates to a device for separating of flat shipments according to the preamble of the claim 1.

Vorrichtungen dieser Art werden insbesondere in Postämtern und Postverteilzentren zum Sortieren von Postsendungen wie Briefe, Zeitschriften oder dgl. verwendet. Das Fördermittel weist Fächer auf, die Trennwände besitzen, welche die Stapel zum Abzugsband transportieren. Die Stapel werden in der Regel von Hand in die Fächer eingelegt. Die Stapel können sehr unterschiedliche Sendungen aufweisen, beispielsweise niedrige und schmale Briefe und dicke, schwere Zeitschriften, die zudem mit einer Kunststofffolie verpackt sein können. Ein Problem bei diesen Vorrichtungen sind Doppelabzugsfehler. Hierbei wird zusätzlich zur vordersten Sendung. eine weitere Sendung abgezogen. Ein Doppelabzug wird insbesondere aufgrund von Haftung zwischen zwei Sendungen oder durch Mitreisskräfte verursacht. Derartige Vorrichtungen sind beispielsweise in der EP - A 0 854 103 zu entnehmen sowie den nachfolgend aufgeführten Dokumenten.Devices of this type are used in particular in post offices and Mail distribution centers for sorting mail items such as letters, Magazines or the like. Used. The funding has subjects on, which have partitions, which the stacks to the conveyor belt transport. The stacks are usually made by Hand inserted in the compartments. The stacks can be very different Have shipments, such as low and narrow letters and thick, heavy magazines that also come with can be packed in a plastic film. A problem with these devices are double deduction errors. Here will in addition to the front shipment. deducted another shipment. A double deduction is due in particular to liability between two shipments or caused by entraining forces. Devices of this type are described, for example, in EP-A 0 854 103 and the documents listed below.

Im Dokument FR 2 692 874 A1 (BERLIN & CIE, FR) ist eine Vorrichtung zum Vereinzeln gestapelter dünner Objekte wie z.B. Briefe offenbart, bei dem vor dem Abziehen der einzelnen im wesentlichen verikal vorliegenden Objekte diese mittels einer angetriebenen Rolle zur Vereinzelung vertikal auf einen Support angehoben werden und nachher weitertransportiert werden. Auf dem Support befinden sich dabei gleichzeitig ein paar wenige Objekte.In document FR 2 692 874 A1 (BERLIN & CIE, FR) there is a device for separating stacked thin objects such as Letters revealed, in which before the deduction of each in objects that are essentially vertically present by means of a driven roller for separating vertically on a support be lifted and then transported on. On the support are a few at the same time Objects.

Gemäss der in JP 61254428 Patent Abstracts of Japan (Toshiba Corp.) offenbarten Lehre erfolgt die Vereinzelung von dünnen Objekten wie z.B. Briefe oder Zeitschriften durch eine Rotation von exzentrisch angeordneter Nocken.According to the in JP 61254428 Patent Abstracts of Japan (Toshiba Corp.) disclosed teaching is done by separating thin Objects such as Letters or magazines by rotation of eccentrically arranged cams.

Zur Vereinzelung von Sendungen wird in DE 1 203 801 (Telefunken Patentverwertungsgellschaft, Ulm) vorgeschlagen, den Stapel solcher Sendung vor dem horizontalen Wegtransport durch einen "geschlossener Luftkreislauf", das heisst durch Luftzirkulation von oben nach unten zu vereinzeln. Dabei ist auf der Stapelauflage eine Vielzahl von Öffnungen vorgesehen, die der Zirkulation der von oben zugeführten Luft dient.DE 1 203 801 (Telefunken Patentverwertungsellellschaft, Ulm) proposed the stack such a shipment before being transported horizontally by one "Closed air cycle", that means through air circulation to separate from top to bottom. It is on the stack pad a variety of openings are provided to allow circulation the air supplied from above.

In US 3,817,516 (Borroughgs Corporation, Detroit) ist eine Vorrichtung für das Ausrichten und Separieren von Briefen offenbart, bei dem die im wesentlichen vertikal angeordneten Briefe über einen sägezahnartigen Keil zur Separation und Ausrichtung geschoben werden, bevor ein Weitertransport erfolgt. In US 3,817,516 (Borroughgs Corporation, Detroit) is an apparatus for aligning and separating letters in which the substantially vertically arranged Letters over a sawtooth wedge for separation and Alignment be pushed before further transport takes place.

Der in FR 2 692 874 A1 und US 3,817,516 gezeigten Lösung ist gemeinsam, dass zwischen der Vereinzelung und dem Weitertransport gleichzeitig wenige Briefe "zwischengestapelt" werden und Doppelabzugsfehler nicht völlig ausschliessen.The solution shown in FR 2 692 874 A1 and US 3,817,516 common that between the separation and the further transport at the same time a few letters "stacked" and do not completely rule out double deduction errors.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung der genannten Art zu schaffen, die sich durch weniger Doppelabzugsfehler auszeichnet und die dennoch kostengünstig herstellbar ist.The invention has for its object a device of the type mentioned, which is characterized by fewer double deduction errors distinguished and which can still be produced inexpensively is.

Diese Aufgabe wird durch die im Patentanspruch 1 angegebenen Merkmale gelöst.This object is achieved by the specified in claim 1 Features resolved.

Es hat sich gezeigt, dass mit der erfindungsgemässen Lösung das Vereinzeln eines am Abzugsspalt angelangten Stapels wesentlich unterstützt. Mitreisskräfte zwischen der vorlaufenden und der nachfolgenden Sendung werden vermindert und damit die Wahrscheinlichkeit eines Doppelabzugsfehlers vermindert. Die gegen die Abzugsbandebene geförderten Sendungen werden durch den Keil angehoben, bis sie vom Abzugsband gefasst und horizontal vom Stapel abgezogen werden. Der Keil bewirkt eine vertikale Bewegung und gegenseitige Verschiebung der aneinander anliegenden Sendungen.It has been shown that with the solution according to the invention separating a stack that has reached the withdrawal gap significantly supported. Entraining forces between the preceding and the subsequent broadcast are reduced and thus reducing the likelihood of a double deduction error. The shipments funded against the level of the conveyor belt are raised by the wedge until they are gripped by the trigger belt and pulled horizontally from the stack. The wedge causes vertical movement and mutual displacement of the consecutive programs.

Gemäss einer Weiterbildung weist der Keil an einer ansteigenden Oberseite Rippen auf, die sich in Abzugsrichtung erstrekken. Die Rippen verhindern ein Abgleiten der Sendungen und unterstützen die vertikale Ausrichtung dieser Sendungen. Da sich die Rippen in Abzugsrichtung erstrecken, wird das Abziehen der Sendungen nicht behindert.According to a further development, the wedge points upwards Top of the ribs that extend in the withdrawal direction. The ribs prevent the shipments from sliding and provide support the vertical orientation of these programs. That I the ribs extend in the withdrawal direction, the withdrawal of the Shipments are not hindered.

Ein besonders wirksames Auffächern wird dann erreicht, wenn der genannte Bereich im wesentlichen vertikal vibrierend bewegt wird. Durch die Vibration werden auf die Sendungen zusätzliche kurze vertikale Bewegungen ausgeübt, welche das Auflockern des Stapels zusätzlich unterstützen. Das Auffächern und Auflockern des Stapels kann auch zusätzlich dadurch verstärkt werden, wenn gemäss einer Weiterbildung durch wenigstens eine Luftöffnung den zu vereinzelnden Sendungen Druckluft zugeführt wird. Vorzugsweise sind mehrere Luftöffnungen in der Aufstellfläche vorgesehen. Damit kann den Sendungen Unterluft zugeführt werden, welche die Sendungen durch ein Luftpolster voneinander trennt und damit Mitreisskräfte wesentlich vermindert. Der genannte Bereich und insbesondere ein Keil als auch die genannten Luftöffnungen können vergleichsweise kostengünstig realisiert werden und sind funktionssicher.A particularly effective fanning out is achieved if said area is vibrated substantially vertically becomes. The vibrations add additional to the shipments exercised short vertical movements, which loosening up of the stack. Fanning out and loosening of the stack can also be reinforced thereby be, if according to a training by at least an air opening for the consignments of compressed air is fed. There are preferably a plurality of air openings provided in the installation area. This can under air the broadcasts are fed, which the shipments through an air cushion separates from one another and thus entraining forces are essential reduced. The area mentioned and in particular a wedge as the air openings mentioned can also be comparatively inexpensive can be realized and are reliable.

Die in den Figuren 1 und 2 gezeigte Vorrichtung 1 weist ein Fördermittel 5 auf, welches im wesentlichen vertikal stehende Stapel 2 in Richtung des Pfeiles 7 gegen eine Abzugsvorrichtung 14 fördert. Das Fördermittel 5 ist beispielsweise ein endloses Band und besitzt in einer Reihe mehrere Fächer, in welche die Stapel 2 beispielsweise von Hand eingelegt werden. Solche Fördermittel 5 sind dem Fachmann bekannt.The device 1 shown in FIGS. 1 and 2 has one Funding 5, which is essentially vertical Stack 2 in the direction of arrow 7 against a trigger device 14 promotes. The funding 5 is, for example endless band and has several compartments in a row, in which the stacks 2 are inserted, for example, by hand. Such funding 5 are known to the person skilled in the art.

Die Stapel 2 bestehen jeweils aus mehreren Sendungen 10, die beispielsweise Briefe, in Folien verpackte Zeitschriften und dergleichen sind. Die Sendungen 10 sind gemäss Figur 2 jeweils mit einer unteren horizontalen Kante 12 auf einer horizontalen Aufstellfläche 6 unterstützt. Mit einer vertikalen vorderen Kante 13 sind die Sendungen 10 an einer vertikalen Anschlagfläche 3 ausgerichtet. Die Anschlagfläche 3 wird beispielsweise durch eine feste Platte 4 gebildet.The stack 2 each consist of several programs 10, the for example letters, magazines wrapped in foil and are like that. The programs 10 are in accordance with FIG. 2 with a lower horizontal edge 12 on a horizontal Footprint 6 supported. With a vertical front Edge 13 are the mail items 10 on a vertical stop surface 3 aligned. The stop surface 3 is, for example formed by a fixed plate 4.

Die Abzugsvorrichtung 14 weist ein endloses flexibles Band 15 auf, das von einer vertikalen Antriebsrolle 16 angetrieben ist und im Abstand zu dieser in einer ebenfalls vertikalen Rolle 17 umgelenkt ist. Das Band 15 weist mehrere Saugöffnungen 9 auf, durch die im Bereich einer Saugvorrichtung 18 Luft von der Aussenseite 8 ins Innere der Saugvorrichtung 18 gesaugt wird. Die Saugvorrichtung 18 weist gemäss Figur 2 einen Saugkanal 19 auf, der mit einer hier nicht gezeigten Vakuumquelle verbunden ist. Zwischen einer vertikalen Abzugsbandebene 8 und der Platte 4 befindet sich ein Abzugsspalt 11, der sich vertikal erstreckt.The trigger device 14 has an endless flexible band 15 on, which is driven by a vertical drive roller 16 and at a distance from it in a likewise vertical role 17 is deflected. The band 15 has a plurality of suction openings 9 on, in the area of a suction device 18 air from the outside 8 sucked into the interior of the suction device 18 becomes. According to FIG. 2, the suction device 18 has a suction channel 19 on that with a vacuum source, not shown here connected is. Between a vertical take-off belt level 8 and the plate 4 is a trigger gap 11, which is vertical extends.

Erreicht gemäss Figur 2 eine vorlaufende Sendung 10a die Abzugsbandebene 8, so wird diese vom Band 15 angesaugt und durch Reibung und Saugluft in Richtung des Pfeils 26 durch den Abzugsspalt 11 hindurch horizontal vom Stapel 2 abgezogen und beispielsweise einer hier nicht gezeigten Lesevorrichtung zugeführt, welche den weiteren Weg der Sendung 10a steuert. Anschliessend wird die nachfolgende Sendung 10b vom Band 15 erfasst und in gleicher Weise abgezogen. Ist ein ganzer Stapel 2 vereinzelt, so wird ein hier nicht gezeigter nachfolgender Stapel in gleicher Weise behandelt.According to FIG. 2, a forwarding consignment 10a reaches the take-off belt level 8, it is sucked in by the belt 15 and through Friction and suction air in the direction of arrow 26 through the trigger gap 11 horizontally withdrawn from the stack 2 and for example a reading device not shown here, which controls the further route of the broadcast 10a. Subsequently the following consignment 10b is captured by the tape 15 and subtracted in the same way. Is a whole stack 2 occasionally, a subsequent one, not shown here, becomes Stack treated in the same way.

In Abzugsrichtung vor dem Abzugsspalt 11 ist auf der Aufstellfläche 6 ein Keil 20 angeordnet, der gemäss Figur 2 zur Abzugsbandebene 8 hin ansteigend ausgebildet ist. Die gegen das Abzugsband 15 hin geförderten Sendungen 10 werden durch diesen Keil 20 nacheinander vertikal angehoben und werden dadurch vertikal aufgefächert. Beim Ansteigen üben die Sendungen 10 eine relative Bewegung zueinander aus. Durch diese relative gegenseitige Bewegung werden Mitreisskräfte zwischen benachbarten Sendungen 10a und 10b vermindert.In the trigger direction in front of the trigger gap 11 is on the installation surface 6, a wedge 20 is arranged, according to FIG. 2 to the take-off belt level 8 is formed increasing. The against that Discharge belt 15 mail items 10 are promoted by this Wedge 20 lifted vertically one after the other and are thereby fanned out vertically. The consignments practice 10 as they rise a relative movement to each other. Through this relative mutual movement become entraining forces between neighboring ones Shipments 10a and 10b reduced.

In Förderrichtung 7 gesehen ist der Keil 20 wenigstens so breit wie der Abzugsspalt 11 und kann gleichzeitig mehrere Sendungen 10 aufnehmen. Rippen 27 und Rillen 28 unterstützen die vertikale Ausrichtung der Sendungen 10. Der in Figur 2 eingezeichnete Neigungswinkel α ist vorzugsweise wesentlich kleiner als 45° und liegt vorzugsweise im Bereich von 10° bis 20°. In Abzugsrichtung gesehen vor den Rippen 27 befindet sich eine aufsteigende Rampe 22, welche verhindert, dass Sendungen 10 am Keil 20 einen Widerstand in Abzugsrichtung 26 erfahren. Die geneigte Oberseite 21 des Keiles 20 kann auch wesentlich kürzer oder länger sein als in Figur 1 gezeigt. Sie kann sich in Figur 1 beispielsweise von der Anschlagfläche 3 bis zur Umlenkrolle 17 erstrecken.Seen in the conveying direction 7, the wedge 20 is at least as follows wide as the trigger gap 11 and can be several at the same time Record programs 10. Support ribs 27 and grooves 28 the vertical alignment of the mail items 10. The in FIG. 2 drawn angle of inclination α is preferably essential less than 45 ° and is preferably in the range of 10 ° to 20 °. Seen in the withdrawal direction is in front of the ribs 27 an ascending ramp 22 which prevents broadcasts 10 experience a resistance in trigger direction 26 on wedge 20. The inclined top 21 of the wedge 20 can also be significant be shorter or longer than shown in Figure 1. You can in Figure 1, for example, from the stop surface 3 to the deflection roller 17 extend.

In Abzugsrichtung 26 gesehen vor dem Keil 20 sind in der Aufstellfläche 6 mehrere Luftlöcher 23 angeordnet, durch welche Druckluft von unten gegen den Stapel 12 zuführbar ist. Die Druckluft ist hier somit Unterluft und ist in Figur 2 von der Aufstellfläche 6 in Richtung der Kanten 13 nach oben gerichtet. Die Luft dringt zwischen die Sendungen 10 und bildet zwischen diesen ein Luftpolster, was ebenfalls Mitreisskräfte beim Abziehen vermindert. Die einströmende Luft unterstützt die Wirkung des Keils 20.Seen in the withdrawal direction 26 in front of the wedge 20 are in the footprint 6 several air holes 23 arranged through which Compressed air can be supplied against the stack 12 from below. The Compressed air is thus under air here and is of the in Figure 2 Footprint 6 directed upwards in the direction of the edges 13. The air penetrates between the programs 10 and forms between this an air cushion, which also entraining forces reduced when pulling off. The incoming air supports the effect of the wedge 20.

Der Keil 20 kann unterschiedlich ausgebildet sein. In der gezeigten Ausführung ist die geneigte Oberseite 28 stufenförmig ansteigend. Denkbar ist auch eine Ausführung, bei welcher die Oberseite 27 beispielsweise durch eine Wölbung gebildet wird. Wesentlich ist die vertikale Auffächerung der Sendungen 10. Wie ersichtlich, ist der Keil 20 so angeordnet, dass die Sendungen 10 in Abzugsrichtung gesehen an ihrem vorderen Ende, d.h. nahe bei der vorderen Kante 13, erfasst und, wie erwähnt, aufgefächert werden. Grundsätzlich kann der Keil 20 aber auch im Abstand zum Abzugsspalt 11 angeordnet sein. The wedge 20 can be designed differently. In the shown Execution is the inclined top 28 step-shaped increasing. An embodiment is also conceivable in which the Top 27 is formed for example by a curvature. The vertical fanning out of the mail items 10 is essential. As can be seen, the wedge 20 is arranged so that the shipments 10 seen in the pull-off direction at its front end, i.e. close to the leading edge 13, and, as mentioned, to be fanned out. Basically, the wedge 20 can also be arranged at a distance from the trigger gap 11.
