Die Erfindung betrifft eine Vorrichtung zum Herausziehen ein¬ zelner flacher Sendungen aus einer Vereinzelungsstrecke nach dem Oberbegriff des Anspruches 1.The invention relates to a device for extracting ein¬ zelner flat broadcasts 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 gegen¬ überliegenden Seite auf einer einseitig angefederten Schwinge angeordnete Andruckrollen oder über sie laufende Bänder me¬ chanisch gefasst und mit höherer Geschwindigkeit weitertrans- portiert (DE 26 13 261 Al, US 5 074 540, US 6 003 857) . Dabei ist eine Lücke der nur einseitig gefassten Sendungen im Rie¬ mentransport bis zu den Übernahmerollen zu verzeichnen. Kurze Sendungen werden also nur teilweise gehalten, was im ungüns¬ tigen Fall zu TransportStörungen, Sendungsdrehungen bzw. Sen- dungsbeschädigungen führen kann. Die Sendungen werden mitThe transmission current generated in the separating line is mechanically grasped by rigid, driven take-up rollers and, on the opposite side, arranged on a cantilevered rocker roller or belts running over it and further transported at a higher speed (DE 26 13 261 A1, US Pat 5 074 540, US 6 003 857). In this case, there is a gap in the shipments which are only recorded on one side in the direction transport up to the transfer rollers. Short shipments are thus held only partially, which in the unfavorable case can lead to transport disruptions, program rotations or transmission damage. The shipments are with
Leitelementen zu den Übernahme/Andruckrollen zentriert. Dünne Sendungen laufen unter einem wesentlich günstigeren Winkel in das Rollenpaar als dicke Sendungen. Bei dicken Sendungen lau¬ fen die Sendungsvorderkanten unter einem ungünstigen Winkel in diese Übernahme/Andruckrollen und werden an den Rollen ge¬ staucht .Guide elements centered on the takeover / pinch rollers. Thin shipments run at a much more favorable angle in the pair of rolls than thick shipments. In the case of thick consignments, the consignment leading edges run at an unfavorable angle into these take-over / pressure rollers and are compressed on the rollers.
Aus der US 3 372 925 ist eine Vorrichtung bekannt, bei der innerhalb einer Vereinzelungsstrecke eine Umlenkrolle eines Transportriemens gemeinsam mit Übernahmerollen auf einer Um- lenkachse angeordnet ist. Dabei werden der Transportriemen und die Übernahmerollen unabhängig voneinander durch einen einzigen Motor angetrieben.

On the opposite side of the transport path, at the level of the take-up rollers, deflection rollers are arranged on pivotable arms, over which belts forming an inlet of the transfer area are guided.
Aus der EP 0 060 596 Bl 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 ange¬ ordnet sind. Vor dem Ausgang der Vereinzelungsstrecke sind den Transportriemen gegenüberliegend an einem schwenkbaren Rahmen gelagerte Rollen angeordnet, über die ein einen Ein- lauf bildender Rahmen geführt ist. Der den Einlauf bildendeFrom 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 jointly arranged ange¬ arranged 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
Riemen und die ihm zugeordneten Rollen sind entgegengesetzt zur Transportrichtung der Sendungen angetrieben. Die verein¬ zelten Sendungen werden vom Ausgang der Vereinzelungsstrecke an über Übernahmerollen geführte Riemen eines Übernahmebe- reichs übergeben.Belt and its associated roles are opposite to the transport direction of the broadcasts driven. The singulated items are transferred from the exit of the singling line to belts of a pick-up area guided by take-over rollers.
Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zum Herausziehen einzelner flacher Sendungen aus einer Ver¬ einzelungsstrecke zu schaffen, bei der die Übernahme der Sen- düngen 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 Ver¬ zufungsstrecke, in which the acquisition of Sen- fertilize regardless of the shipment thickness is largely bumpless and the broadcasts regardless of their length at any time are completely guided ,
Erfindungsgemäß wird die Aufgabe durch die Merkmale des An- Spruches 1 gelöst.According to the invention, the object is achieved by the features of claim 1.
Dabei sind die einzeln gelagerten Umlenkrollen der Transport¬ riemen am Ausgang der Vereinzelungsstrecke mit unabhängig von den Transportriemen angetriebenen Übernahmerollen eines sich anschließenden Übernahmebereiches auf einer gemeinsamen Um¬ lenkachse drehbar angeordnet. Auf der Gegenseite des Trans¬ portpfades sind in Höhe der Übernahmerollen die Sendungen ge- gen die Übernahmerollen mit Federkraft drückende Andruckrol¬ len vorgesehen, die in einem in Abzugsrichtung vor ihnen und seitlich versetzt vom Transportkanal befindlichen, örtlich festen Drehpunkt schwenkbar gelagert sind, in welchem syn¬ chron mit den Übernahmerollen angetriebene Rollen drehbar ge- lagert sind. Über die schwenkbaren Andruckrollen und die an¬ getriebenen Rollen sind einen Einlauf bildende Riemen ge¬ führt. Durch die Anordnung der letzten Umlenkrollen der Ver¬ einzelungsstrecke und der Übernahmerollen auf einer gemeinsa¬ men Umlenkachse wird also eine Lücke im Transportpfad der einseitig gefassten Sendungen vermieden. Da die Sendungsvor¬ derkanten immer unter dem gleichen Winkel auf die den Einlauf bildenden Riemen treffen, erfolgt eine sendungsschonende Ein¬ leitung der Transportkraft unabhängig von der Sendungsdicke.In this case, the individually mounted deflection rollers of the transport belts at the exit of the separation path are independent of The transfer belt driven transfer rollers of a subsequent transfer area on a common Um¬ steering axis rotatably arranged. On the opposite side of the transport path, in the amount of take-over rollers, the mail items are provided with pressure rollers pressing with spring force, which are pivotably mounted in a locally fixed pivot point in front of them and laterally offset from the transport channel Syn¬ chron with the take-over rollers driven rollers are stored rotatably. About the pivotable pinch rollers and the an¬ driven rollers an inlet forming belt are ge leads. Due to the arrangement of the last deflection rollers of the Ver¬ einzelungsstrecke and takeover rollers on a gemeinsa¬ men deflection axis so a gap in the transport path of unilaterally recorded broadcasts is avoided. Since the consignment front edges always hit the belt forming the inlet at the same angle, a transmission-friendly introduction of the transporting force takes place independently of the mailing thickness.
Vorteilhafte Ausgestaltungen der Erfindung sind in den Unter¬ ansprüchen dargelegt .Advantageous embodiments of the invention are set forth in the dependent claims.
So ist es vorteilhaft, senkrecht zur Transportrichtung in Hö¬ he der Umlenkachse der Übernahmerollen einen Sensor zur De- tektierung 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 rear edges of the items perpendicular to the transport direction at height of the deflection axis of the take-up rollers, in order to control the drives of the separating line with the detection signals.
Vorteilhaft ist es auch, in der Vereinzelungsstrecke bis zu den Übernahmerollen ein angetriebenes Unterflurband vorzuse¬ hen, auf dem die vereinzelten, einseitig gefassten Sendungen beim Transport stehen. Dadurch wird der Transport insbesonde¬ re von dicken schweren Sendungen unterstützt.It is also advantageous to provide a driven underfloor belt in the separation path up to the take-over rollers, on which the separated, one-sided programs are in transit. As a result, the transport is particularly supported by heavy heavy shipments.

Der Übergang des letzten Transportabschnittes der Vereinze¬ lungsstrecke 1 zur Übergabeeinheit soll ohne Transportlücke zueinander realisiert werden. Die in der Vereinzelungsstre¬ cke 1 durch ein Rückhalteband 2 gegen die hintersten Trans- portriemen 3 angedrückte und durch eine Vakuumkammer 4 zu¬ sätzlich angesaugte Sendung 5 wird in Pfeilrichtung S trans¬ portiert . Eventuell anhaftende Mehrfachabzüge werden durch den hohen Reibwert des Rückhaltebandes 2 zurückgehalten. Zur Unterstützung des Transportes der Sendungen 5 in der Verein- zelungsstrecke 1 stehen sie auf einem angetriebenen Unter¬ flurband 21. Der am Ende der Vereinzelungsstrecke 1 angeord¬ nete Übernahmebereich 6 besteht im vorliegenden Beispiel aus Übernahmerollen 7 mit Antriebsriemen 8 und dazugehörendem Mo¬ tor 9 sowie einer angefederten Riemenschwinge 10 mit Andruck- rollen 11 und Schwingenriemen 12. Der Schwingendrehpunkt 14 liegt hierbei in der Antriebsachse der synchron zu den Über¬ nahmerollen 7 angetriebenen Rollen 13 für die Schwingenrie¬ men 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 Übernahme- stelle in der Höhe alternierend mit den Antriebsriemen 8 aus dem Übernahmebereich 6 ab. Durch die gemeinsame Umlenkach¬ se 17 der letzten Umlenkrollen 16 der Vereinzelungsstrecke 1 und der Übernahmerollen 7 wird ein absolut lückenfreier Transportübergang ermöglicht. Der Einlauf der Sendungsvorder- kanten in die Riemenschwinge 10, d.h. die Berührung derThe transition of the last transport section of the separating track 1 to the transfer unit should be realized without a transport gap to each other. The consignment 5, which is pressed into the separating strip 1 by a retaining band 2 against the rearmost transport belt 3 and additionally sucked in by a vacuum chamber 4, is trans ported 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 mail items 5 in the singling line 1, they are positioned on a driven underfloor belt 21. In the present example, the takeover area 6 arranged at the end of the singling line 1 consists of pickup rollers 7 with drive belt 8 and associated motor 9 and a spring-loaded belt rocker 10 with pressure rollers 11 and rocker belt 12. The rocker pivot point 14 lies in the drive axle of the rollers 13 for the rocker belts 12 which are driven in synchronism with the transfer rollers 7. The pressure rollers 11 are pressed by a pressure spring 15 against the rollers Drive belt 8 pressed 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 transport belts 3 of the separation line 1 alternate at the transfer point in the amount of alternately with the drive belt 8 from the transfer area 6 from. Due to the common Umlenkach¬ se 17 of the last pulleys 16 of the separation line 1 and the take-over rollers 7 an absolutely gap-free transport transition is possible. The entrance of the mailing front edges into the belt rocker 10, i. the touch of the
Schwingenriemen 12 erfolgt unabhängig von der Sendungsdicke immer unter dem gleichen Winkel . Wird der Schwingendreh- punkt 14 relativ dicht am Transportpfad angeordnet, d.h. der Einlaufwinkel der Schwinge 10 zum Transportpfad ist klein, treten keine unzulässigen Stoßbelastungen der Sendungen un¬ terschiedlicher Dicke auf. Nachdem eine SendungsVorderkante eine Lichtschranke 18/l8a an der Übernahmestelle verdunkelt hat, kann im Bedarfsfall der Antriebsmotor der Transportrie¬ men 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 Umlenk- rollen 19 dargestellt sind. Zur Adaption an die unterschied¬ lichen Sendungsdicken ist eine der beiden Umlenkrollen 19 ge¬ gen eine Andruckfeder 20 auslenkbar. Da die Sendungen 5 so¬ wohl zwischen den Übernahme- und Andruckrollen 7,11 als auch zwischen den Umlenkrollen 19 des DeckbandtransportSystems si- eher gefasst sind, hat die geringe Lücke dazwischen im Trans¬ portpfad keine negativen Auswirkungen. Swing belt 12 always takes place at the same angle regardless of the mailing thickness. If the swingarm Point 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 un¬ different thickness occur. After a mailing leading edge has darkened a light barrier 18 / 18a at the transfer location, if necessary the drive motor of the transport line 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 evtl. Adhesive double prints are additionally separated in this start stop mode. In short distance after the. Transfer point then follows a shroud transport system for further transport of the consignments, of which the first deflection rollers 19 are shown. For adaptation to the different transmission thicknesses, one of the two deflection rollers 19 can be deflected against a pressure spring 20. Since the items 5 are more likely to be seized between the take-up and pinch rollers 7, 11 and between the deflection rollers 19 of the shroud transport system, the small gap between them in the transport path has no negative effects.
