Description
Die auf Postsendungen wie Briefen, Postkarten, Päckchen und dergleichen, als Kennzahl für einen Ort, einen Zustellbereich, ein Postfach oder einen Großempfänger anzugebenden, maschinenlesbaren Postleitzahlen, ermöglichen eine rasche maschinelle Verteilung der Post. Das Sortieren der ankommenden Postsendungen erfolgt beispielsweise mit Hilfe von steuerbaren Stückgutträgern, die in speziellen Beladeplätzen mit jeweils einer Postsendung beladen werden, und diese Postsendung dann an einen der jeweiligen Postleitzahl zugeordneten Sortierbehälter oder ein entsprechendes Sortierfach abgeben. Da die Sortierbehälter oder Sortierfächer in verschiedenen Ebenen angeordnet sein können, müssen die an Fördereinrichtungen umlaufenden Stückgutträger gegebenenfalls auch verschiedene Höhenlagen überbrücken können. Nach der Übergabe der Postsendung an den zugeordneten Sortierbehälter oder das zugeordnete Sortierfach, können die leeren Stückgutträger beim Passieren eines Beladeplatzes erneut mit einer Postsendung beladen werden. Das Beladen der Stückgutträger erfolgt beispielsweise mit Hilfe eines umlaufenden Flügelrades, dessen Flügel Zellen bilden, die das bereits vereinzelte und auf einer Fördereinrichtung ankommende Stückgut aufnehmen und an die umlaufenden Stückgutträger abgeben. Die Vereinzelung und die Übergabe des Stückguts an die zu dem Flügelrad führende Fördereinrichtung, muß dabei mit einer an die Verarbeitungsgeschwindigkeit der gesamten Sortiereinrichtung angepaßten, relativ hohen Genauigkeit vorgenommen werden.The on mail items such as letters, postcards, packages and the like, as a key figure for a location, a delivery area, a mailbox or a bulk recipient, machine-readable postcodes, enable a quick machine Distribution of mail. Sorting the incoming Postal items are, for example, controlled General cargo carriers that are in special loading areas with each loaded with a mail item, and this mail item then to one assigned to the respective zip code Hand in the sorting container or an appropriate sorting compartment.

Die Figuren 1 und 2 zeigen in stark vereinfachter schematischer Darstellung eine Vorrichtung zur Vereinzelung und zur Übergabe von Stückgut S an eine mit F bezeichnete Fördereinrichtung in der Seitenansicht bzw. in der Draufsicht. Zur Aufnahme des hier in Form von Zeitschriften und Zeitungen unterschiedlichen Formats und unterschiedlichen Gewichts vorliegenden Stückguts S und zur Bereitstellung dieses Stückguts S in einer vorderen Abholposition A, ist eine mit E bezeichnete Einrichtung vorgesehen. Bei dieser in Figur 2 nicht dargestellten Einrichtung E handelt es sich um einen schrittweise in Richtung auf die Abholposition A antreibbaren, horizontal ausgerichteten Bandförderer, auf welchen das Stückgut S von Hand stapelweise in aufrechter, leicht nach vorne geneigter Stellung aufgebracht wird. Figures 1 and 2 show in a highly simplified schematic Representation of a device for separating and Transfer of piece goods S to a conveyor designated F in side view or in plan view. For Inclusion of the different here in the form of magazines and newspapers Format and different weight present General cargo S and for the provision of this general cargo S in a front pick-up position A is one labeled E Facility provided. In this, not shown in Figure 2 Facility E is a gradual one drivable in the direction of the pick-up position A, horizontally aligned belt conveyor on which the general cargo S by hand in stacks in an upright, slightly inclined forward Position is applied.
Zum Ergreifen des in der Abholposition A bereitgestellten Stückguts S ist eine oberhalb der Fördereinrichtung F um ihre Längsachse LA drehbar angeordnete Trommel T vorgesehen, in deren Mantel insgesamt drei nebeneinander liegende Saugöffnungen SO eingebracht sind. Die taschenförmigen Saugöffnungen SO sind über Saugkanäle SK mit dem Inneren einer Hohlwelle HW verbindbar, auf welcher sich die Trommel T dreht. Das Innere der Hohlwelle HW ist seinerseits an eine in der Zeichnung nicht näher dargestellte Vakuumquelle angeschlossen. Durch die in Figur 1 erkennbare segmentförmige Öffnung der Hohlwelle HW im Bereich der Saugkanäle SK, entsteht eine Art Drehschieber, über welchen die Saugöffnungen SO beim Erreichen der Abholposition A an die Vakuumquelle angeschlossen werden. Das in der Abholposition A bereitgestellte Stückgut S wird somit durch die Saugwirkung der Saugöffnungen SO von der Trommel T ergriffen und in tangentialer Richtung der Trommel T vom verbleibenden Stapel leicht schräg nach oben abgezogen. Nach einer Drehung der Trommel T von mehr als 180° und weniger als 270°, unterbricht der bereits erwähnte, durch die Hohlwelle HW gebildete Drehschieber die Verbindung der Saugöffnungen SO mit der Vakuumquelle und das vereinzelte Stückgut S wird auf die Fördereinrichtung F abgeworfen.For gripping the one provided in pick-up position A. General cargo S is one above the conveyor F around its Longitudinal axis LA rotatably arranged drum T is provided in whose jacket a total of three adjacent suction openings SO are introduced. The pocket-shaped suction openings SO are via suction channels SK with the inside of a hollow shaft HW connectable, on which the drum T rotates. The inner the hollow shaft HW is in turn connected to one in the drawing Vacuum source not shown connected. By the recognizable segment-shaped opening of the hollow shaft in Figure 1 HW in the area of the suction channels SK, a kind arises Rotary slide valve, through which the suction openings SO when reaching collection position A connected to the vacuum source will. The general cargo S provided in pickup position A. is thus by the suction of the suction openings SO Drum T gripped and in the tangential direction of the drum T slightly pulled off the remaining stack at an angle. After a rotation of the drum T of more than 180 ° and less than 270 °, interrupts the one already mentioned, by the Hollow shaft HW formed rotary valve connecting the suction openings SO with the vacuum source and the individual piece goods S is dropped onto the conveyor F.
Die als Stückgut S auf dem Förderband der Einrichtung E mit dem Rücken oder Falz nach unten aufgestellten und nach vorne zur Trommel T hin leicht geneigten Zeitschriften oder Zeitungen, können durch zwei im Abstand zueinander angeordnete Abweiser AW von einer Berührung der Trommel T abgehalten werden. Soll dann das in der Abholposition A bereitgestellte Stückgut S über die Ansaugöffnungen AO ergriffen werden, so werden die beiden Abweiser AW in zugeordnete rillenförmige Vertiefungen V der Trommel T zurückgezogen. Das Ein- und Ausrücken der auf der Welle WE befestigten Abweiser AW erfolgt durch entsprechende Drehungen der Welle WE.The as piece goods S on the conveyor belt of the device E with the back or fold down and forward magazines or newspapers slightly inclined towards the drum T, can by two deflectors arranged at a distance from each other AW be prevented from touching the drum T. Then should that provided in pickup position A. General cargo S can be gripped via the suction openings AO, see above are the two deflectors AW in assigned groove-shaped Recesses V of the drum T withdrawn. Engaging and disengaging the AW deflector attached to the shaft WE by corresponding rotations of the shaft WE.
Im Bereich zwischen der Abholposition A und der Stelle für den Abwurf des Stückguts S auf die Fördereinrichtung F, ist der Trommel T eine Führungseinrichtung FE für das Stückgut S zugeordnet. Diese Führungseinrichtung FE ist durch ein endlos umlaufendes Band B gebildet, welches über drei Umlenkrollen UR derart geführt ist, daß es die Trommel T im gewünschten Führungsbereich umschlingt. Die Umlaufrichtung des Bandes B ist in Figur 1 durch einen Pfeil PF aufgezeigt. Das Band B kann dabei angetrieben werden oder aber auch durch die mit der Drehzahl n umlaufende Trommel T reibschlüssig mitgenommen werden.In the area between the pick-up position A and the point for the discharge of the piece goods S onto the conveyor F is the drum T a guide device FE for the piece goods S assigned. This guide device FE is by an endless revolving band B formed, which over three pulleys UR is performed such that it is the drum T in the desired Loops around the leadership area. The direction of rotation of the tape B is shown in Figure 1 by an arrow PF. The volume B can be driven or with the the speed n revolving drum T frictionally entrained will.
Das nur in Figur 1 dargestellte Band B ist in mehrere parallel verlaufende Riemen unterteilt. Auf diese Weise kann in dem Bereich zwischen den drei Umlenkrollen UR ein optischer Sensor SS angeordnet werden, der an dieser Stelle zwischen zwei Riemen Anfang und/oder Ende des jeweils von der Trommel T mitgenommenen Stückguts S erfaßt. Aus Figur 2 ist ersichtlich, daß das Signal SI des Sensors SS einer Steuereinrichtung SE zugeführt wird. Diese Steuereinrichtung SE beeinflußt ihrerseits über ein Ausgangssignal AS einen Antriebsmotor AM, welcher über einen Riementrieb RT und die mit TW bezeichnete Trommelwelle die Trommel T antreibt. Die Lagerung der Trommelwelle TW ist in Figur 2 durch Kugellager KL angedeutet.The band B shown only in Figure 1 is parallel in several running straps divided. In this way, the area between the three pulleys UR an optical Sensor SS can be arranged at this point between two straps beginning and / or end of each of the drum T captured piece goods S recorded. From Figure 2 it can be seen that the signal SI of the sensor SS of a control device SE is supplied. This control device SE influences in turn a drive motor AM via an output signal AS, which via a belt drive RT and the one marked TW Drum shaft drives the drum T. The storage of the drum shaft TW is indicated in Figure 2 by ball bearings KL.
Der Sensor SS erfaßt somit die Position des von den Saugöffnungen SSO erfaßten Stückguts S auf der Trommel T. Ein vom Sensor SS gegebenenfalls ermittelter Schlupf beim Ergreifen und der Mitnahme des Stückguts S, kann somit über die Steuereinrichtung SE durch eine entsprechende Veränderung der Drehzahl n der Trommel T kompensiert werden.The sensor SS thus detects the position of the suction openings SSO recorded piece goods S on the drum T. One from Sensor SS, if found, slip when gripping and the transport of the piece goods S, can thus via the control device SE by changing the speed accordingly n drum T can be compensated.
Bei der das vereinzelte Stückgut S aufnehmenden Fördereinrichtung F, handelt es sich im dargestellten Ausführungsbeispiel um einen Bandförderer, dessen nicht näher bezeichnetes Förderband sich mit der Geschwindigkeit u in Transportrichtung bewegt. Auf dem Förderband schaffen Querrippen QR eine Teilung t für die Aufnahme und den Weitertransport des Stückguts S. Die Geschwindigkeit u der Fördereinrichtung F und die Drehzahl n der Trommel T sind derart aufeinander abgestimmt, daß eine Übergabe des Stückguts S an die Fördereinrichtung F bei jeder Teilung t oder jeweils einem ganzzahligen Vielfachen der Teilung t der Fördereinrichtung F erfolgt. Durch Veränderung der Drehzahl n der Trommel T kann die Übergabe des Stückguts S gegebenenfalls auch auf eine ungleichmäßige Teilung der Fördereinrichtung F abgestimmt werden.At the conveyor device that receives the individual piece goods S. F, it is in the illustrated embodiment a belt conveyor, the unspecified Conveyor belt moving at speed u in the direction of transport emotional. Cross ribs QR create one on the conveyor belt Division t for picking up and transporting the piece goods S. The speed u of the conveyor F and the The speed n of the drum T are coordinated with one another in such a way that that a transfer of the piece goods S to the conveyor F with each division t or an integer multiple the division t of the conveyor F takes place. By Changing the speed n of the drum T can transfer the piece goods S, if necessary, also to an uneven Division of the conveyor F can be coordinated.
Die vorstehend beschriebene Vorrichtung zur Vereinzelung und zur Übergabe von Stückgut S führt zu einem umlaufenden Flügelrad, dessen durch die einzelnen Flügel gebildeten Zellen das auf der Fördereinrichtung F ankommende Stückgut S aufnehmen und nach einer entsprechenden Drehung an daruner umlaufende Stückgutträger einer Sortiereinrichtung abgeben.The device for separation and described above for the transfer of piece goods S leads to a rotating impeller, the cells formed by the individual wings pick up the piece goods S arriving on the conveyor device F. and after a corresponding rotation on the revolving one Deliver general cargo carriers to a sorting facility.
