Abstract
Description
Die Erfindung betrifft eine Vorrichtung zur Richtungsumkehr von flachen Sendungen in Sendungssortieranlagen mit zuführenden und abführenden Deckbandfördermitteln.
In Sendungssortieranlagen, in denen flache Sendungen u.a. Lese- und Druckeinrichtungen zugeführt werden, um die Sendungen entsprechend auf ihrer Oberfläche aufgebrachter Verteilinformationen zu sortieren, müssen sich diese Verteilinformationen an festgelegten Positionen befinden. Ist dies nicht der Fall, so müssen die Sendungen durch Drehung um ihre Längs- und/oder Hochachse in die Arbeitsposition gebracht werden.The invention relates to a device for reversing the direction of flat shipments in consignment sorting systems with feeding and discharging cover belt conveyors.
In consignment sorting plants, where flat items of information are supplied to reading and printing devices in order to sort the items corresponding to distribution information applied to their surface, this distribution information must be in fixed positions. If this is not the case, the consignments must be brought by rotation about their longitudinal and / or vertical axis in the working position.
Dazu wurde eine Vorrichtung zur Richtungsumkehr (die Vorderkante wird zur Hinterkante nach der Wiedereinschleusung in den Sendungsstrom) bekannt(
Entsprechende baulich kompakte Vorrichtungen zur Richtungsumkehr von flachen Sendungen mit zwei Umkehrvorrichtungen sind aus
Weiterhin wird in
Der Erfindung liegt die Aufgabe zugrunde, eine aufwandsarme Vorrichtung zur Richtungsumkehr von flachen Sendungen in Sendungssortieranlagen mit zu- und abführenden Deckbandfördermitteln zu schaffen, mit der eine kollisionsfreie Drehung von flachen, mit kleinen Abständen aufeinander folgenden Sendungen um ihre Hochachse möglich ist.The invention has for its object to provide a low-cost device for reversing the direction of flat shipments in consignment sorting with incoming and outgoing shroud conveyors, with a collision-free rotation of flat, with small intervals successive programs is possible about its vertical axis.
Erfindungsgemäß wird die Aufgabe durch die Merkmale des Anspruches 1 gelöst.
Dem zuführenden Deckbandfördermittel, bestehend aus zwei endlosen, umlaufenden Bändern, zwischen denen die Sendungen eingeklemmt hintereinander transportierbar sind, folgt eine Weiche zur Aufteilung der Sendungen im Wechsel auf zwei im spitzen Winkel auseinander laufende Deckbandtransportstrecken mit jeweils zwei endlosen Bändern, denen sich jeweils eine gesteuert und reversierbar antreibbare Förderstrecke, in der die Sendungen ebenfalls geklemmt transportierbar sind, anschließt. Beide Förderstrecken sind durch eine zwischen ihnen angeordnete Antriebsrolle antreibbar und die Sendungen sind in einem solchen Umschlingungswinkel um die Antriebsrolle führbar, dass die Sendungen unter Berücksichtigung der Reibkräfte annähernd rutschfrei abbremsbar und beschleunigbar sind. Jede Förderstrecke ist so ausgeführt, dass die Sendungen beim Rücktransport unter einem spitzen Winkel zur jeweiligen zuführenden Deckbandtransportstrecke in ein abführendes Deckbandtransportmittel mit zwei endlosen, umlaufenden Bändern leitbar sind. Der Abbremsvorgang wird erst gestartet, wenn die Hinterkante der jeweiligen Sendung die Deckbandtransportstrecke verlassen hat. Zu jedem Zeitpunkt sind die Sendungen in der Vorrichtung kraftschlüssig geführt.According to the invention the object is achieved by the features of
The feeding shroud conveyor, consisting of two endless circulating belts, between which the shipments are trapped in a row, follows a switch for splitting the programs alternately on two apart at an acute angle Deckbandtransportstrecken with two endless belts, which each one controlled and reversible drivable conveyor line, in which the items are also transported clamped, connects. Both conveyor sections can be driven by a drive roller arranged between them and the items can be guided around the drive roller in such a wrap angle that the items can be braked and accelerated approximately slip-free, taking into account the frictional forces. Each conveyor line is designed so that the items can be routed during return transport at an acute angle to the respective feeding shroud transport path in a laxative shroud transport means with two endless, circulating belts. The braking process is only started when the trailing edge of the respective program has left the shroud transport path. At any time, the broadcasts are frictionally guided in the device.
Somit ist es möglich, Sendungsströme mit kleinen Lücken zwischen den Sendungen mit nur einer Vorrichtung zur Richtungsumkehr zu verarbeiten.Thus, it is possible to process broadcast streams with small gaps between broadcasts with only one direction reversal device.
Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen dargelegt.
Um die Sendungen wieder in den Sendungsstrom einzuschleusen, sind die beiden die Sendungen beim Rücktransport abführenden Deckbandtransportmittel vorteilhaft an eine Zusammenführung mit einem Ausgang führbar.Advantageous embodiments of the invention are set forth in the subclaims.
In order to feed the mailings back into the mail stream, the two mailings which transport the mailings during the return transport can advantageously be guided to a merger with an exit.
Damit gewährleistet ist, dass auch Sendungen ohne Umkehrung die Vorrichtung ohne Behinderung durchlaufen können, ist es vorteilhaft, die Enden der gesteuert und reversierbar antreibbaren Förderstrecken soweit voneinander entfernt anzuordnen, dass ohne Richtungsumkehr weiterzutransportierende Sendungen ohne Behinderung zu einem sich anschließenden dritten abführenden Deckbandtransportmittel transportierbar sind.To ensure that even transmissions without reversal can pass through the device without hindrance, it is advantageous to arrange the ends of the controlled and reversibly drivable conveyor lines far away from each other that weiterzutransportierende broadcasts can be transported without obstruction to a subsequent third laxative shroud transport without direction reversal.
Zur aufwandsarmen Ausführung der gesteuert und reversierbar antreibbaren Förderstrecken ist es vorteilhaft, wenn diese jeweils aus einem äußeren, endlosen Deckband, das über zwei Umlenkrollen geführt ist, und einem gemeinsamen inneren Deckband, das über die Antriebsrolle und eine weitere Umlenkrolle geführt ist, bestehen.For low-cost execution of the controlled and reversibly driven conveyor lines, it is advantageous if they each consist of an outer, endless shroud, which is guided over two pulleys, and a common inner shroud, which is guided over the drive roller and a further deflection roller.
Eine weitere Möglichkeit zur aufwandsarmen Ausführung der gesteuert und reversierbar antreibbaren Förderstrecken, aber bei eingeschränktem Sendungsformatspektrum, besteht darin, für diese jeweils ein äußeres, endloses Deckband, das über zwei Umlenkrollen geführt ist, und die gemeinsame Antriebsrolle vorzusehen.A further possibility for the low-effort execution of the controlled and reversibly drivable conveyor lines, but with limited range of broadcast formats, is to provide for these in each case an outer, endless shroud, which is guided over two pulleys, and the common drive roller.
Um diese Einschränkungen im Sendungsformatspektrum zu beseitigen, ist es vorteilhaft, zum Klemmen der Sendungen in beiden Förderstrecken noch eine nicht angetriebene Andruckrolle vorzusehen.To eliminate these limitations in the broadcast format spectrum, it is advantageous to provide a non-driven pressure roller for clamping the programs in both conveyor lines.
Vorteilhaft ist es auch, jeweils als äußeres endloses Band jeder der Weiche folgenden Deckbandtransportstrecke und als inneres endloses Band des zugeordneten, beim Rücktransport abführenden Deckbandtransportmittels nur ein angetriebenes, durch Rollen geführtes umlaufendes Endlosband vorzusehen. Dadurch kann ein angetriebenes, endloses, umlaufendes Band eingespart werden.It is also advantageous, in each case as an outer endless band of each of the points following shroud transport path and provide as an inner endless belt of the associated, the return transport dissipating shroud transport means only a driven, guided by rolling revolving endless belt. As a result, a driven, endless, circulating belt can be saved.
Weiterhin ist es vorteilhaft, als Detektionsmittel für die Sendungshinterkanten eine Lichtschranke einzusetzen.Furthermore, it is advantageous to use a light barrier as the detection means for the mailing trailing edges.
Anschließend wird die Erfindung in einem Ausführungsbeispiel anhand der Zeichnung erläutert.

Die flachen Sendungen 30,31,32 werden über ein hier nicht im einzelnen dargestelltes Deckbandfördermittel 1 und eine steuerbare Weiche 2 abwechselnd auf zwei im spitzen Winkel auseinander laufende zuführende Deckbandtransportstrecken geleitet. Die rechte Deckbandtransportstrecke besteht aus einem ersten endlosen Band 3, das über eine erste Umlenkrolle 4 umgelenkt und zurückgeführt wird, und einem zweiten endlosen Band 5, das über eine zweite Umlenkrolle 6 umgelenkt und zurückgeführt wird. Dementsprechend analog besteht auch die linke Deckbandtransportstrecke aus einem dritten endlosen Band 9, das über eine dritte Umlenkrolle 10 umgelenkt und zurückgeführt wird, und einem vierten endlosen Band 11, das über eine vierte Umlenkrolle 12 umgelenkt und zurückgeführt wird.
Jede Deckbandtransportstrecke leitet die Sendungen in eine gesteuert und reversierbar angetriebene Förderstrecke. Beide Förderstrecken laufen in Einlaufrichtung unter einem spitzen Winkel zusammen. Die der rechten Deckbandtransportstrecke folgende Förderstrecke besteht aus einem fünften, äußeren endlosen Band 15, das über zwei Umlenkrollen 16 umgelenkt wird und einem sechsten, inneren endlosen Band 17, das über eine größere Antriebsrolle 18 und eine kleinere Umlenkrolle 19 läuft. Dieses endlose Band 17 ist gleichzeitig auf der gegenüberliegenden Seite das innere endlose Band der der linken Deckbandtransportstrecke folgenden Förderstrecke, die noch ein siebtes, äußeres endloses Band 20, welches über zwei Umlenkrollen 21 umgelenkt wird, aufweist.
Die nahe beieinander befindlichen Umlenkrollen 16,21 der Förderstrecken weisen einen solchen Abstand voneinander auf, dass die dicksten Sendungen 30,31,32, die nicht zurücktransportiert werden müssen oder die länger als die reversierbare Förderstrecke sind, durch den Spalt zwischen den Umlenkrollen 16,21 ungehindert einem folgenden Transportmittel zugeführt werden können. Da die Transportrichtungen der Deckbandtransportstrecken und der jeweils nachfolgenden Förderstrecken zueinander geneigt sind, ergibt sich ein notwendiger Umschlingungswinkel, mit dem die Sendungen 30,31,32 um die Antriebstrommel 18 geführt werden.
Da die Förderstrecken nach innen geneigt sind, werden die Sendungen 30,31,32 beim Rücktransport außen an den zuführenden Deckbandtransportstrecken und dem zuführenden Deckbandfördermittel 1 vorbei beidseitig in abführende Deckbandtransportmittel geleitet. Diese bestehen jeweils aus äußeren, über Umlenktrommeln 8,14 umgelenkten endlosen Bändern 7,13 und inneren Bändern 3,9, welche gleichzeitig die äußeren Bänder der zuführenden Deckbandtransportstrecken sind.
Dadurch, dass die Sendungen 30,31,32 im Wechsel auf die zuführenden Deckbandtransportstrecken aufgeteilt werden und somit im Wechsel auf den gegenüberliegenden Seiten der Antriebstrommel 18 in die reversierbaren Förderstrecken geführt werden, ist es nicht mehr notwendig wie bisher, die vorhergehende Sendung 31 aus der Umkehrförderstrecke herauszufahren, bevor die nachfolgende Sendung 32 in diese hineinfährt. Es ist nur notwendig, dass die Antriebstrommel 18 ihre Nenngeschwindigkeit erreicht hat, wenn die nachfolgende Sendung 32 in die Umkehrförderstrecke eben mit dieser Nenngeschwindigkeit einfährt und dass der Abbremsvorgang erst begonnen wird, sobald die Hinterkante der in die reversierbare Förderstrecke einfahrenden Sendung 32 die zuführende Deckbandtransportstrecke und die vorherige Sendung 31 die reversierbare Förderstrecke verlassen hat. Damit ist es möglich, trotz der Bremsund Beschleunigungsvorgänge mit nur einer Antriebstrommel 18 kleine Lücken zwischen den reversierten Sendungen 30,31,32 zu realisieren. Wann die Vorder- und Hinterkanten der Sendungen 30,31,32 die beschriebenen Positionen erreicht haben, wird mittels Lichtschranken Li1 bis Li3 und des Streckentaktes ermittelt.The
