Description

Vorliegende Erfindung betrifft eine Vorrichtung zum Aufrichten von flachen Sendungen gemäß dem Oberbegriff des Patentanspruchs 1.The present invention relates to an erecting device of flat shipments according to the preamble of the claim 1.

In Briefverteilanlagen werden Briefe und ähnliche flache Sendungen in bestimmten Phasen des Bearbeitungsprozesses mittels Bändersystemen befördert. Üblicherweise bestehen diese Bändersysteme aus einem im wesentlichen horizontal angeordnetem Grundband und einem aus Ober- und Unterband bestehenden Deckband, zwischen denen die Sendungen befördert werden. Die Sendungen stehen dabei auf einer Kante. Bei der Beförderung solcher Bändersysteme auftretendes Problem besteht darin, daá die Sendungen in Schrägstellung einen Höhenversatz aufweisen. Beides kann bei der weiteren Bearbeitung der Sendungen zu Störungen führen, insbesondere zu Staus und einer Verschiebung der Lücken zwischen den Sendungen der zu Beschädigungen führt.Letters and similar flat items are placed in mail distribution systems in certain phases of the machining process Conveyor systems promoted. These belt systems usually exist from a substantially horizontally arranged Baseband and a top and bottom band, between which the shipments are transported. The shipments stand on one edge. When transporting such The problem with tape systems is that the consignments have an offset in height. Both can be done in the further processing of the shipments Disruptions lead, in particular, to traffic jams and a shift the gaps between shipments to damage leads.

Eine mögliche Lösung dieses Problems bestände darin, das Gewicht der Sendung auszunutzen und die Sendung in einem bestimmten Abschnitt des Bandsystems quasi von allein unter dem Einfluß der Schwerkraft sich ausrichten zu lassen. Dabei wird die Sendung losgelassen, so daß Lückenverschiebungen bestehen könnten. Außerdem könnte durch elektrostatische Aufladung der Sendungen eine Ausrichtung verhindert werden.One possible solution to this problem is weight to take advantage of the shipment and the shipment in a particular Section of the tape system almost by itself under the The influence of gravity. Doing so released the shipment so that there are gaps could. In addition, the electrostatic charge could Shipments an alignment can be prevented.

In der DE 1 817 472 U wird eine Vorrichtung zum Drehen von flachen Sendungen um eine senkrecht zu ihrer Ebene stehende Achse, die auf einer Kante stehend mit einem Bändersystem mit einem Deckband transportiert werden, beschrieben. In einem vorgegebenen Abschnitt befindet sich ein angetriebenes Rollenpaar, dessen gemeinsame Achse im wesentlichen senkrecht zur Förderrichtung angeordnet ist, wobei die erste Rolle oberhalb des Deckbandes und die zweite Rolle unterhalb des Deckbandes angeordnet ist. Zur Durchführung der Drehung besitzt die obere Rolle eine höhere, feste Drehgeschwindigkeit als die untere Rolle, so daß ein die Lage der Sendung veränderndes Moment ausgeübt wird. Ein gezieltes Ausrichten von Sendungen ist hiermit nicht möglich.DE 1 817 472 U describes a device for rotating flat shipments around a perpendicular to their plane Axis standing on an edge with a belt system be transported on a cover tape. In one predetermined section is a driven pair of rollers, whose common axis is substantially perpendicular is arranged to the conveying direction, the first roller above the cover tape and the second roll below the Shroud is arranged. To perform the rotation the upper roller has a higher, fixed rotation speed than the lower roll, so that the position of the broadcast changes Moment is exercised. A targeted alignment of Shipments are not possible with this.

In einer Vorrichtung zum Ausrichten von Blättern (EP-A-0 431 267) wird mit Hilfe einer Sensoreinrichtung die Lage der jeweiligen Sendung ermittelt. Wird eine Schräglage detektiert, so erfolgt eine Aktivierung derjenigen zwei von mehreren Rollen, deren Eingriff die Ausrichtung am besten bewirkt. Eine Rolle wird dann solange mit einer festen Drehzahl angetrieben und die andere Rolle abgebremst, bis die Schrägstellung ausgeglichen ist. Ein geregeltes Verändern der Geschwindigkeiten der Rollen gemäß der Art und Größe der Schrägstellung unter Beibehaltung der Abstände zwischen den Sendungen erfolgt hierbei nicht.In a device for aligning sheets (EP-A-0 431 267) is using a sensor device Location of the respective shipment determined. Becomes a lean detected, the two of those are activated several roles, the engagement of which best effects alignment. A roll will then run at a fixed speed driven and the other roller braked until the inclination is balanced. A regulated change of speeds of the rolls according to the type and size of the Inclination while maintaining the distances between the Shipments are not made here.

Gemäß der US-A-4 836 527 wird die Schräglage eines Dokumentes ausgeglichen, indem eine angetriebene Rolle auf einem schwenkbaren Arm befestigt ist und gegen eine Federkraft ausgelenkt wird. Dies erfolgt allerdings ungeregelt, so daß bestimmte Bedingungen bei unterschiedlichen Formaten und Abständen zwischen den Sendungen bei hoher Transportgeschwindigkeit nicht einzuhalten sind.According to US-A-4 836 527 the skew of a document balanced by a driven roller on one pivotable arm is attached and deflected against a spring force becomes. However, this is unregulated, so that certain Conditions with different formats and distances between shipments at high transport speeds are not to be observed.

Aufgabe der vorliegenden Erfindung ist die Angabe einer Vorrichtung zum Ausrichten von flachen Sendungen, die mittels eines Bändersystems befördert werden, bei der insbesondere Lückenverschiebungen zwischen den Sendungen vermieden werden.The object of the present invention is to provide a device for the alignment of flat consignments, which means of a conveyor system, in particular Gaps between the shipments can be avoided.

Diese Aufgabe wird durch die Merkmale des Patentanspruchs 1 gelöst. Vorteilhafte Ausführungsformen der Erfindung sind in Unteransprüchen der Beschreibung zu entnehmen. This object is achieved by the features of patent claim 1 solved. Advantageous embodiments of the invention are in Subclaims can be found in the description.

Die Erfindung geht von der Idee aus, Sendungen während des Ausrichtungsvorgangs durch ein steuerbares Rollenpaar reibschlüssig zu fassen und durch eine Änderung der Drehgeschwindigkeit oder der Orientierung der Rollen ein die Lage der Sendungen relativ zum Bändersystem veränderndes Moment auf die Sendungen auszuüben. Dadurch ist eine Richtstrecke unabhängig von ihrer Einbaulage.The invention is based on the idea of broadcasts during the Alignment process by a controllable pair of rollers frictionally grasp and by changing the rotational speed or the Orientation of the roles and the position of the shipments relative to Tape system to exert a changing moment on the programs. Thereby is a straightening section regardless of its installation position.

Mit der erfindungsgemäßen Vorrichtung ist es möglich, Lückenverschiebungen zu vermeiden und auch schwierige Sendungsarten zu bearbeiten. Insbesondere wird vermieden, daß Sendungen beschädigt werden, insgesamt wird die Störanfälligkeit der gesamten Briefverteilanlage reduziert.With the device according to the invention, it is possible to shift gaps to avoid and difficult shipment types too to edit. In particular, it is avoided that shipments are damaged overall, the entire mail distribution system becomes susceptible to faults reduced.

Die in FIG. 1 dargestellte erfindungsgemäße Vorrichtung weist ein aus Grundband 1 und dem Deckband 2 bestehendes Bändersystem auf, das eine flache Sendung 3 auf einer Kante stehend befördert. Zur Führung und zum Antrieb der Bänder sind Rollen 4 vorgesehen. Das Deckband besitzt im Normalbetrieb eine Nenngeschwindigkeit VN. Ein Rollenpaar 5 und 6 mit einer gemeinsamen Drehachse 7, die im wesentlichen senkrecht zur Förderrichtung der Sendungen angeordnet ist, ist oberhalb bzw. unterhalb des Deckbandes 2 angeordnet. Da die Sendung 3 nur hinten vom Deckband bedeckt wird, können die Rollen 5 und 6 an der Sendung 3 anliegen und sie reibschlüssig fassen. Sobald eine Sendung von den Rollen gefaßt wird, kann über diese ein Moment auf die Sendung 3 ausgeübt werden, um deren Lage in Bezug auf das Bändersystem zu verändern. Vorzugsweise kann hierfür eine der Rollen mit einer der Nenngeschwindigkeit Vn entsprechenden Geschwindigkeit rotieren, während die zweite Rolle eine davon abweichende Geschwindigkeit

Figure 00040001
V aufweist. Die Differenz zwischen den beiden Geschwindigkeiten führt zur Ausbildung eines Drehmoments auf die Sendung, so daß eine Lagekorrektur, falls erforderlich vorgenommen werden kann. Bei der bevorzugten Ausführungsform der FIG. 1 wird die obere Reibrolle 5 von einem Servomotor angetrieben; die untere Rolle sitzt direkt auf einer Hohlwelle auf der Motorachse mit der Nenngeschwindigkeit Vn. Der Antrieb dieser zweiten Rolle erfolgt vorzugsweise über einen Riemen 8 und einer Riemenscheibe 9, FIG. 2.The in FIG. The device according to the invention shown in FIG. 1 has a belt system consisting of the base belt 1 and the cover belt 2, which conveys a flat mail item 3 standing on one edge. Rollers 4 are provided for guiding and driving the belts. In normal operation, the shroud has a nominal speed VN. A pair of rollers 5 and 6 with a common axis of rotation 7, which is arranged substantially perpendicular to the conveying direction of the mail items, is arranged above and below the cover band 2. Since the consignment 3 is only covered by the cover tape at the rear, the rollers 5 and 6 can rest against the consignment 3 and grasp them by friction. As soon as a shipment is gripped by the rolls, a moment can be exerted on the shipment 3 in order to change its position in relation to the conveyor system. For this purpose, one of the rollers can preferably rotate at a speed corresponding to the nominal speed Vn, while the second roller has a speed deviating therefrom
Figure 00040001
V. The difference between the two speeds leads to the formation of a torque on the item, so that a position correction can be made if necessary. In the preferred embodiment of FIG. 1, the upper friction roller 5 is driven by a servo motor; the lower roller sits directly on a hollow shaft on the motor axis with the nominal speed V n . This second roller is preferably driven by a belt 8 and a pulley 9, FIG. 2nd

Die Lage der Sendung wird durch zwei in Förderrichtung vor dem Rollenpaar 5, 6 angeordnete Sensoren 10 erfaßt. Vorzugsweise sind dafür Lichtschranken vorgesehen. Mit einer weiteren Sensoreinrichtung 11 wird die Lage der Sendung während sie von den Rollen 5 und 6 gefaßt ist, erfaßt. Die Sensoren 10 und 11 sind mit der in den Figuren 1 und 2 nicht dargestellten Steuerelektronik verbunden. Um die Drehung der Sendung zu erleichtern, wird von einem Hubmagneten 12 eine Gegenrolle 13, die um eine Achse 14 schwenkbar ist und gegen das Deckband 2 drückt, weggerückt, sobald die Sendung gegenüber dem Bändersystem bewegt werden soll.The position of the shipment is determined by two in the conveying direction in front of the pair of rollers 5, 6 arranged sensors 10 detects. Preferably for that Light barriers provided. With a further sensor device 11 Location of the shipment while it is held by the reels 5 and 6 detected. The sensors 10 and 11 are not the same as in FIGS. 1 and 2 control electronics shown connected. To the rotation of the broadcast too facilitate, a counter roller 13 by a solenoid 12, which is a Axis 14 is pivotable and presses against the cover band 2, moved away, as soon as the shipment is to be moved in relation to the conveyor system.

FIG. 3 zeigt eine weitere Ausführungsform der Erfindung mit einem Rollenpaar 15, 16, das auf einer gemeinsamen schwenkbaren Achse 17 angeordnet ist. Die Achse sitzt auf einem Chassis 19, das an einem Drehpunkt 18 angelenkt ist. Die Schwenkbewegung wird vorzugsweise über eine Zahnstange und ein von einem Servo- oder Schrittmotor angetriebenes Zahnrad 21 geschwenkt. Ein Motor 22 treibt über einen Riemen 23 und eine Riemenscheibe 24 die Achse 17 an. FIG. 4 zeigt die Vorrichtung der FIG. 3 in Obenansicht. Gegenüber dem Rollenpaar 15, 16 ist eine angefederte Gegenrolle 25 angeordnet um die reibschlüssige Fassung der Sendung 3 zu verbessern. Die Gegenrolle 25 ist auf dem gleichen Chassis angeordnet wie das Rollenpaar 15, 16. Die Rolle 25 wird durch einen Hubmgnet weggerückt, um die Bewegung der Sendung zwischen dem Deckband 2 zu erleichtern. Die Rollen 15 und 16 werden mit einer der Nenngeschwindigkeit Vn entsprechenden Drehgeschwindigkeit angetrieben, so daß eine von den Rollen 15 und 16 gefaßte Sendung durch das Schwenken der Drehachse 17 bewegt werden kann.FIG. 3 shows a further embodiment of the invention with a pair of rollers 15, 16, which is arranged on a common pivotable axis 17. The axle sits on a chassis 19 which is articulated at a pivot point 18 is. The pivoting movement is preferably via a rack and a gear 21 driven by a servo or stepper motor. A motor 22 drives the belt 23 and a pulley 24 Axis 17 on. FIG. 4 shows the device of FIG. 3 in top view. A spring-loaded counter roller 25 is opposite the pair of rollers 15, 16 arranged to improve the frictional version of the program 3. The Counter roller 25 is arranged on the same chassis as the pair of rollers 15, 16. The roller 25 is moved away by a Hubmgnet to the To facilitate movement of the shipment between the shroud 2. The roles 15 and 16 are at a speed corresponding to the nominal speed Vn Rotational speed driven so that one of the rollers 15 and 16th recorded consignment can be moved by pivoting the axis of rotation 17 can.

Einige der wichtigsten Sendungsrichtvorgänge sind in FIG. 5 für die Vorrichtung gemäß der Figuren 1 und 2 dargestellt. 5a zeigt den Fall einer Sendung, deren Hinterkante angehoben ist. Bei einer Sendung einer gegenüber der Richtgeschwindigkeit um V verringerten Geschwindigkeit der Rolle 5 wird die Sendungshinterkante in Richtung auf das Grundband 2 bewegt. Anschließend wird die Rolle 5 mit der Geschwindigkeit Vn angetrieben. Figur 5b zeigt den Fall einer Sendung mit angehobener Vorderkante. Durch Anwendung einer gegenüber der Geschwindigkeit Vn erhöhten Geschwindigkeit V wird die Vorderkante abgesenkt, anschließend wird die Rolle mit der Geschwindigkeit Vn weiterbetrieben. Figur 5c zeigt den Fall einer waagerecht der dem Grundband angehobenen Sendung, in diesem Fall wird im vorderen Bereich der Sendung zunächst eine Geschwindigkeit V angesendet, die zu einer Senkung der Hinterkante der Sendung führt. Anschließend wird analog wie in FIG. 5b eine Geschwindigkeit + V angewendet, die zu einer Absenkung der Vorderkante führt. Während dieser Richtvorgänge ist eine Sendung von Rollen gefaßt, so daß keine Lückenverschiebung zwischen den Sendungen auftritt.Some of the most important shipment directing processes are shown in FIG. 5 for the device according to FIGS. 1 and 2. 5a shows the case of a shipment whose rear edge is raised. In the case of a consignment compared to the target speed V reduced speed of the roll 5, the rear edge of the mail item is moved in the direction of the base belt 2. The roller 5 is then driven at the speed Vn. Figure 5b shows the case of a shipment with the leading edge raised. By using a speed that is higher than the speed Vn V the front edge is lowered, then the roll continues to operate at the speed Vn. FIG. 5c shows the case of a shipment that is raised horizontally on the base band, in this case there is a speed in the front area of the shipment V sent, which leads to a lowering of the rear edge of the broadcast. Then, as in FIG. 5b a speed + V applied, which leads to a lowering of the leading edge. During this straightening process, a shipment of rolls is gripped so that there is no gap shift between the shipments.
