Description

Die Erfindung betrifft eine Vorrichtung zum Herausziehen einzelner flacher Sendungen aus einer Vereinzelungsstrecke nach dem Oberbegriff des Anspruches 1.The invention relates to a device for extracting individual flat items from a separating line according to the preamble of claim 1.

Der in der Vereinzelungsstrecke erzeugte Sendungsstrom wird durch starre, angetriebene Übernahmerollen und auf der gegenüberliegenden Seite auf einer einseitig angefederten Schwinge angeordnete Andruckrollen oder über sie laufende Bänder mechanisch gefasst und mit höherer Geschwindigkeit weitertransportiert ( DE 26 13 261 A1 , US 5 074 540 , US 6 003 857 ). Dabei ist eine Lücke der nur einseitig gefassten Sendungen im Riementransport bis zu den Übernahmerollen zu verzeichnen. Kurze Sendungen werden also nur teilweise gehalten, was im ungünstigen Fall zu Transportstörungen, Sendungsdrehungen bzw. Sendungsbeschädigungen führen kann. Die Sendungen werden mit Leitelementen zu den Übernahme/Andruckrollen zentriert. Dünne Sendungen laufen unter einem wesentlich günstigeren Winkel in das Rollenpaar als dicke Sendungen. Bei dicken Sendungen laufen die Sendungsvorderkanten unter einem ungünstigen Winkel in diese Übernahme/Andruckrollen und werden an den Rollen gestaucht.
Aus der US 3 372 925 ist eine Vorrichtung bekannt, bei der innerhalb einer Vereinzelungsstrecke eine Umlenkrolle eines Transportriemens gemeinsam mit Übernahmerollen auf einer Umlenkachse angeordnet ist. Dabei werden der Transportriemen und die Übernahmerollen unabhängig voneinander durch einen einzigen Motor angetrieben. Nach der endgültigen Vereinzelung durch eine Vereinzelungsrolle werden die Sendungen am Ausgang der Vereinzelungsstrecke an eine Übernahme- und eine Andruckrolle eines sich an die Vereinzelungsstrecke anschließenden Übernahmebereichs übergeben. Dabei wird die in einem seitlich versetzt vom Transportkanal befindlichen, örtlich festen Drehpunkt schwenkbar gelagerte Andruckrolle durch die Kraft einer Feder gegen die Übernamerolle gedrückt. Eine schwenkbar gelagerte Platte bildet einen Einlauf für den Übernahmebereich.
Aus der US 3 894 732 ist eine Vorrichtung bekannt, bei der am Ausgang einer Vereinzelungsstrecke Umlenkrollen eines Transportriemens und Übernahmerollen eines Übernahmebereichs gemeinsam angetrieben und fest auf einer gemeinsamen Umlenkachse angeordnet sind. Auf der Gegenseite des Transportpfades in Höhe der Übernahmerollen sind an schwenkbaren Armen Umlenkrollen angeordnet, über die einen Einlauf des Übernahmebereichs bildende Riemen geführt sind.
Aus der EP 0 060 596 B1 ist eine Vorrichtung bekannt, bei der am Ausgang einer Vereinzelungsstrecke eine Umlenkrolle eines Transportriemens und eine weitere Umlenkrolle eines weiteren Transportriemens gemeinsam angetrieben auf einer Achse angeordnet sind. Vor dem Ausgang der Vereinzelungsstrecke sind den Transportriemen gegenüberliegend an einem schwenkbaren Rahmen gelagerte Rollen angeordnet, über die ein einen Einlauf bildender Rahmen geführt ist. Der den Einlauf bildende Riemen und die ihm zugeordneten Rollen sind entgegengesetzt zur Transportrichtung der Sendungen angetrieben. Die vereinzelten Sendungen werden vom Ausgang der Vereinzelungsstrecke an über Übernahmerollen geführte Riemen eines Übernahmebereichs übergeben.The transmission current generated in the separating line is mechanically gripped by rigid, driven take-up rollers and on the opposite side arranged on a cantilevered rocker pinch rollers or belts running over them and further transported at higher speed ( DE 26 13 261 A1 . US 5 074 540 . US 6,003,857 ). There is a gap in the unilaterally recorded shipments in the belt transport up to the takeover rolls. Short shipments are therefore only partially held, which in the worst case can lead to transport disruptions, shipment rotations or shipment damage. The consignments are centered with guide elements to the takeover / pinch rollers. Thin shipments run at a much more favorable angle in the pair of rolls than thick shipments. For thick broadcasts, the leading edges of the programs run at an unfavorable angle into these takeover / pressure rollers and are compressed on the rollers.
From the US 3,372,925 a device is known in which within a separating line a deflection roller of a transport belt is arranged together with take-over rollers on a deflection axis. The transport belt and take-over rollers are driven independently of each other by a single motor. After the final separation by a separation role, the items are handed over at the exit of the separation line to a takeover and a pinch roller of a subsequent to the separation track takeover area. Here, in a laterally offset from the transport channel, locally fixed Pivot pivotally mounted pinch roller pressed by the force of a spring against the supertooth. A pivotally mounted plate forms an inlet for the takeover area.
From the US 3,894,732 a device is known in which at the output of a separating line deflection rollers of a conveyor belt and take-over rollers of a transfer area are driven together and fixedly arranged on a common deflection axis. On the opposite side of the transport path in the amount of takeover rollers deflection rollers are arranged on pivotable arms, are guided over which an inlet of the transfer region forming belt.
From the EP 0 060 596 B1 a device is known in which at the output of a separating line a deflection roller of a transport belt and a further deflection roller of a further transport belt are driven together on an axis. Before the exit of the separating line, the transport belts are arranged opposite rollers mounted on a pivotable frame, over which a frame forming an inlet is guided. The inlet forming belt and its associated roles are opposite to the transport direction of the broadcasts driven. The individual shipments are transferred from the exit of the singling line to take-over belts guided by a pick-up area.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zum Herausziehen einzelner flacher Sendungen aus einer Vereinzelungsstrecke zu schaffen, bei der die Übernahme der Sendungen unabhängig von der Sendungsdicke weitgehend stoßfrei erfolgt und die Sendungen unabhängig von ihrer Länge zu jeder Zeit vollständig geführt werden.The invention has for its object to provide a device for extracting individual flat broadcasts from a separating line, in which the takeover of the broadcasts regardless of the shipment thickness is largely bumpless and the broadcasts are performed regardless of their length at any time completely.

Erfindungsgemäß wird die Aufgabe durch die Merkmale des Anspruches 1 gelöst.
Dabei sind die einzeln gelagerten Umlenkrollen der Transportriemen am Ausgang der Vereinzelungsstrecke mit unabhängig von den Transportriemen angetriebenen Übernahmerollen eines sich anschließenden Übernahmebereiches auf einer gemeinsamen Umlenkachse drehbar angeordnet. Auf der Gegenseite des Transportpfades sind in Höhe der Übernahmerollen die Sendungen gegen die Übernahmerollen mit Federkraft drückende Andruckrollen vorgesehen, die in einem in Abzugsrichtung vor ihnen und seitlich versetzt vom Transportkanal befindlichen, örtlich festen Drehpunkt schwenkbar gelagert sind, in welchem synchron mit den Übernahmerollen angetriebene Rollen drehbar gelagert sind. Über die schwenkbaren Andruckrollen und die angetriebenen Rollen sind einen Einlauf bildende Riemen geführt. Durch die Anordnung der letzten Umlenkrollen der Vereinzelungsstrecke und der Übernahmerollen auf einer gemeinsamen Umlenkachse wird also eine Lücke im Transportpfad der einseitig gefassten Sendungen vermieden. Da die Sendungsvorderkanten immer unter dem gleichen Winkel auf die den Einlauf bildenden Riemen treffen, erfolgt eine sendungsschonende Einleitung der Transportkraft unabhängig von der Sendungsdicke.According to the invention the object is achieved by the features of claim 1.
The individually mounted pulleys of the conveyor belt at the output of the separation line with independent of the transfer belt driven transfer rollers of a subsequent transfer area rotatably arranged on a common deflection axis. On the opposite side of the transport path, the shipments against the takeover rollers are provided with spring pressure pressing rollers provided in a withdrawal direction in front of them and laterally offset from the transport channel, locally fixed pivot point are pivotally mounted in which synchronously with the take-over rollers driven rollers are rotatably mounted. About the pivotable pinch rollers and the driven rollers an inlet forming belt are guided. Due to the arrangement of the last pulleys of the separation line and the takeover rollers on a common deflection axis so a gap in the transport path of unilaterally recorded broadcasts is avoided. Since the consignment front edges always meet at the same angle to the inlet forming belt, a gentle transport introduction of the transport force is independent of the shipment thickness.

Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen dargelegt.Advantageous embodiments of the invention are set forth in the subclaims.

So ist es vorteilhaft, senkrecht zur Transportrichtung in Höhe der Umlenkachse der Übernahmerollen einen Sensor zur Detektierung der Vorder- und/oder Hinterkanten der Sendungen anzuordnen, um mit den Detektionssignalen die Antriebe der Vereinzelungsstrecke zu steuern.Thus, it is advantageous to arrange a sensor for detecting the front and / or trailing edges of the items perpendicular to the transport direction at the level of the deflection axis of the transfer rollers in order to control the drives of the separation line with the detection signals.

Vorteilhaft ist es auch, in der Vereinzelungsstrecke bis zu den Übernahmerollen ein angetriebenes Unterflurband vorzusehen, auf dem die vereinzelten, einseitig gefassten Sendungen beim Transport stehen. Dadurch wird der Transport insbesondere von dicken schweren Sendungen unterstützt.It is also advantageous to provide a driven underfloor belt in the separating line up to the take-over rollers, on which stand the isolated, one-sided programs during transport. As a result, the transport is particularly supported by heavy heavy shipments.

Anschließend wird die Erfindung in einem Ausführungsbeispiel anhand der Zeichnung erläutert.Subsequently, the invention will be explained in an embodiment with reference to the drawing.

Der Übergang des letzten Transportabschnittes der Vereinzelungsstrecke 1 zur Übergabeeinheit soll ohne Transportlücke zueinander realisiert werden. Die in der Vereinzelungsstrecke 1 durch ein Rückhalteband 2 gegen die hintersten Transportriemen 3 angedrückte und durch eine Vakuumkammer 4 zusätzlich angesaugte Sendung 5 wird in Pfeilrichtung S transportiert. Eventuell anhaftende Mehrfachabzüge werden durch den hohen Reibwert des Rückhaltebandes 2 zurückgehalten. Zur Unterstützung des Transportes der Sendungen 5 in der Vereinzelungsstrecke 1 stehen sie auf einem angetriebenen Unterflurband 21. Der am Ende der Vereinzelungsstrecke 1 angeordnete Übernahmebereich 6 besteht im vorliegenden Beispiel aus Übernahmerollen 7 mit Antriebsriemen 8 und dazugehörendem Motor 9 sowie einer angefederten Riemenschwinge 10 mit Andruckrollen 11 und Schwingenriemen 12. Der Schwingendrehpunkt 14 liegt hierbei in der Antriebsachse der synchron zu den Übernahmerollen 7 angetriebenen Rollen 13 für die Schwingenriemen 12. Die Andruckrollen 11 werden über eine Andruckfeder 15 gegen die Antriebsriemen 8 an den Übernahmerollen 7 gedrückt. Die einzeln gelagerten Umlenkrollen 16 der Transportriemen 3 aus der Vereinzelungsstrecke 1 und die Übernahmerollen 7 aus dem Übernahmebereich 6 sind an der Übernahmestelle auf einer gemeinsamen Umlenkachse 17 montiert. Die Transportriemen 3 der Vereinzelungsstrecke 1 wechseln sich an der Übernahmestelle in der Höhe alternierend mit den Antriebsriemen 8 aus dem Übernahmebereich 6 ab. Durch die gemeinsame Umlenkachse 17 der letzten Umlenkrollen 16 der Vereinzelungsstrecke 1 und der Übernahmerollen 7 wird ein absolut lückenfreier Transportübergang ermöglicht. Der Einlauf der Sendungsvorderkanten in die Riemenschwinge 10, d.h. die Berührung der Schwingenriemen 12 erfolgt unabhängig von der Sendungsdicke immer unter dem gleichen Winkel. Wird der Schwingendrehpunkt 14 relativ dicht am Transportpfad angeordnet, d.h. der Einlaufwinkel der Schwinge 10 zum Transportpfad ist klein, treten keine unzulässigen Stoßbelastungen der Sendungen unterschiedlicher Dicke auf. Nachdem eine Sendungsvorderkante eine Lichtschranke 18/18a an der Übernahmestelle verdunkelt hat, kann im Bedarfsfall der Antriebsmotor der Transportriemen 3 der Vereinzelungsstrecke 1 abgeschaltet werden. Die Sendung 5 wird ab diesem Moment durch die Übernahmeeinheit mit den Übernahme- und Andruckrollen 7,11 gegen die stehenden Transportriemen 3 der Vereinzelungsstrecke 1 herausgezogen. Der Sendung 5 evtl. anhaftende Doppelabzüge werden in diesem Start Stopp Mode zusätzlich getrennt. In kurzem Abstand nach der Übernahmestelle folgt dann ein Deckbandtransportsystem zum Weitertransport der Sendungen, von dem die ersten Umlenkrollen 19 dargestellt sind. Zur Adaption an die unterschiedlichen Sendungsdicken ist eine der beiden Umlenkrollen 19 gegen eine Andruckfeder 20 auslenkbar. Da die Sendungen 5 sowohl zwischen den Übernahme- und Andruckrollen 7,11 als auch zwischen den Umlenkrollen 19 des Deckbandtransportsystems sicher gefasst sind, hat die geringe Lücke dazwischen im Transportpfad keine negativen Auswirkungen.The transition of the last transport section of the separating line 1 to the transfer unit should be realized without a transport gap to each other. The in the separation line 1 pressed by a retaining band 2 against the rearmost conveyor belt 3 and additionally sucked by a vacuum chamber 4 program 5 is transported in the direction of arrow S. Possibly adhering multiple deductions are retained by the high coefficient of friction of the retaining band 2. To support the transport of the items 5 in the separation line 1, they stand on a driven underfloor belt 21. The transfer area 6 arranged at the end of the separation line 1 consists in the present example of transfer rollers 7 with drive belt 8 and associated motor 9 and a spring-loaded belt rocker 10 with pinch rollers 11 and swingarm 12. The swing pivot 14 is in this case in the drive axis of the synchronously driven to the take-over rollers 7 rollers 13 for the swingarms 12. The pinch rollers 11 are pressed by a pressure spring 15 against the drive belt 8 to the take-over rollers 7. The individually mounted deflection rollers 16 of the transport belt 3 from the separating line 1 and the take-over rollers 7 from the transfer area 6 are mounted on the transfer point on a common deflection axis 17. The conveyor belt 3 of the separation line 1 alternate at the transfer point in height alternately with the drive belt 8 from the transfer area 6 from. Due to the common deflection axis 17 of the last deflection rollers 16 of the separating line 1 and the take-over rollers 7 an absolutely gap-free transport transition is possible. The inlet of the mailing leading edges into the belt rocker 10, that is, the contact of the rocker belt 12 is always independent of the shipment thickness at the same angle. Will the swing pivot 14 arranged relatively close to the transport path, ie, the inlet angle of the rocker 10 to the transport path is small, no inadmissible shock loads of the shipments of different thickness occur. After a mailing leading edge has darkened a light barrier 18 / 18a at the transfer point, if necessary the drive motor of the transport belt 3 of the singling line 1 can be switched off. The consignment 5 is pulled from this moment by the transfer unit with the takeover and pinch rollers 7,11 against the stationary conveyor belt 3 of the separation line 1. The program 5 possibly adhering double prints are additionally separated in this start stop mode. At a short distance after the transfer point then follows a Deckbandtransportsystem for further transport of the shipments, of which the first guide rollers 19 are shown. For adaptation to the different transmission thicknesses, one of the two deflection rollers 19 is deflectable against a pressure spring 20. Since the shipments 5 are securely gripped both between the take-over and pressure rollers 7, 11 and between the guide rollers 19 of the shroud transport system, the small gap between them in the transport path has no negative effects.
