Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben.An embodiment of the invention is in the drawing shown and is described in more detail below.
Es zeigen
Figur 1 zeigt in stark vereinfachter schematischer Darstellung eine Übergabeeinrichtung für Stückgut. Diese Übergabeeinrichtung umfaßt ein umlaufendes Flügelrad FR, dessen um die durch ein Kreuz angedeutete Radachse RA fest angeordnete Flügel F sektorförmige Zellen Z bilden, die das auf einer ersten Fördereinrichtung FE1 ankommende Stückgut S aufnehmen und an umlaufende Stückgutträger ST einer zweiten Fördereinrichtung FE2 abgeben.Figure 1 shows a highly simplified schematic representation a transfer device for general cargo. This transfer device comprises a rotating impeller FR, the order of the wheel axis RA indicated by a cross Wing F form sector-shaped cells Z, which on a first incoming device FE1 pick up incoming general cargo S. and to circulating general cargo carriers ST of a second conveyor Submit FE2.
Bei dem durch strickpunkitierte Linien angedeuteten Stückgut S handelt es sich beispielsweise um Briefe, die an drei Aufgabestellen von oben her auf eine in Figur 1 lediglich durch eine strichpunktierte Linie angedeutete weitere Fördereinrichtung FEW aufgegeben werden. Von dort wird das Stückgut S dann an die erste Fördereinrichtung FE1 übergeben und direkt in eine Zelle Z des Flügelrades FR transportiert. Beim Drehen des Flügelrades FR in Drehrichtung DR verhindert dann zunächst ein endloses Band BE, daß das Stückgut S aus den Zellen Z herausfällt. Das über insgesamt drei Rollen RO geführte endlose Band EB wird dabei reibschlüssig vom Flügelrad FR angetrieben, wodurch eine unerwünschte Relativbewegung zwischen dem endlosen Band EB und dem Stückgut S vermieden wird. Nach dem endlosen Band EB fällt das Stückgut S dann aus den Zellen Z im Abgabebereich in die zugeordneten Stückgutträger ST der zweiten Fördereinrichtung FE2. Die in Bezug auf einen gedachten inneren Kreis des Flügelrades FR tangentiale Ausrichtung der Flügel F ermöglicht dabei im Übergabebereich eine Anpassung an die Neigung der Stückgutträger ST.In the case of the piece goods indicated by chain-dotted lines S is, for example, letters sent to three posting points from above to only one in FIG a further conveyor device indicated by a dash-dotted line FEW to be abandoned. From there, the general cargo S then handed over to the first conveyor FE1 and directly transported into a cell Z of the impeller FR. When turning of the impeller FR in the direction of rotation DR initially prevents an endless belt BE that the general cargo S from the cells Z falls out. The guided over a total of three roles RO endless belt EB is frictionally engaged by the impeller FR driven, causing an undesirable relative movement between the endless belt EB and the general cargo S is avoided. After the endless belt EB, the general cargo S then falls out of the Cells Z in the delivery area in the assigned general cargo carriers ST of the second conveyor FE2. The one regarding imaginary inner circle of the impeller FR tangential alignment the wing F enables in the transfer area an adaptation to the inclination of the general cargo carrier ST.
Bei den Stückgutträgern ST der zweiten Fördereinrichtung FE2 handelt es sich um Komponenten einer Sortiereinrichtung für Postgut, deren Aufbau und Wirkungsweise beispielsweise in den älteren Patentanmeldungen P 43 23 564.6 und 43 23 565.4 beschrieben ist.In the case of the general cargo carriers ST of the second conveyor FE2 are components of a sorting device for Postage, its structure and mode of operation, for example in the older patent applications P 43 23 564.6 and 43 23 565.4 described is.
Die Geschwindigkeit v1 und der Teilungsabstand t1 des auf der weiteren Fördereinrichtung FEW und der ersten Fördereinrichtung FE1 ankommenden Stückguts S, die Umfangsgeschwindigkeit u und die Umfangsteilung t2 des Flügelrades FR und die Geschwindigkeit v3 und die Teilung t3 der umlaufenden Stückgutträger ST sind dabei so aufeinander abgestimmt, daß stets eine gleichbleibend sichere Übergabe des Stückguts S gewährleistet ist. Die Geschwindigkeit v1 und der Teilungsabstand t1 des ankommenden Stückguts S sind dabei so gewählt, daß jeweils die nächste leerstehende Zelle Z des mit gleichbleibender Winkelgeschwindigkeit umlaufenden Flügelrades FR beladen werden kann. Die Umfangsteilung t2 der Flügel F des Flügelrades FR und die Teilung t3 der Stückgutträger ST sind so aufeinander abgestimmt, wie die Teilungen von Zahnrad und Zahnstange, die miteinander im Eingriff stehen. Zusätzlich muß dabei jedoch noch die Umfangsgeschwindigkeit u des Flügelrades FR und die Geschwindigkeit v3 der Stückgutträger ST so aufeinander abgestimmt sein, daß die Horizontalkomponenten dieser Geschwindigkeiten gleich sind und die dargestellte Zuordnung der Umfangsteilung t2 der Zellen Z im Umfangsbereich zu der Teilung t3 der Stückgutträger ST erhalten bleibt.The speed v1 and the pitch t1 of the on the further conveyor FEW and the first conveyor FE1 incoming piece goods S, the peripheral speed u and the circumferential pitch t2 of the impeller FR and the speed v3 and the division t3 of the rotating general cargo carriers ST are so coordinated that always a consistently safe transfer of the general cargo S is guaranteed is. The speed v1 and the division distance t1 of the incoming piece goods S are chosen so that each the next empty cell Z of the same Load the angular velocity of the rotating impeller FR can be. The circumferential pitch t2 of the wing F of the impeller FR and the division t3 of the general cargo carrier ST are so matched to each other, like the divisions of gear and Rack that mesh with each other. In addition However, the circumferential speed u of the impeller must still be used FR and the speed v3 of the general cargo carrier ST be coordinated so that the horizontal components these speeds are the same and that shown Assignment of the circumferential division t2 of the cells Z in the circumferential area get the division t3 of the general cargo carrier ST remains.
Aus Figur 1 ist auch ersichtlich, daß jeweils vier Stückgutträger ST zu einer Gruppe, beispielsweise zu einem Wagen zusammengefaßt sind, und daß jeweils zwischen zwei Gruppen von Stückgutträgern ST eine Lücke L2 besteht. Aus diesem Grund ist das Flügelrad FR mit fest angeordneten Zusatzflügeln ZF ausgerüstet, die jeweils mit dem in Drehrichtung DR gesehen nacheilenden Flügel F Leerzellen LZ bilden, die den vorstehend erwähnten Lücken L2 zwischen zwei Gruppen von Stückgutträgern ST zugeordnet sind. Auch bei der Beladung der weiteren Fördereinrichtung FEW mit Stückgut S muß den Lücken L2 bzw. den Leerzellen LZ dadurch Rechnung getragen werden, daß jeweils nach vier Aufgaben der Teilungsabstand t1 um einen entsprechenden Ausgleichsbetrag Δt erhöht wird.From Figure 1 it can also be seen that four general cargo carriers ST combined into a group, for example into a car and that between two groups of General cargo carriers ST there is a gap L2. For this reason is the vane FR with fixed additional vanes ZF equipped, each with the seen in the direction of rotation DR trailing wing F form empty cells LZ, which the above mentioned gaps L2 between two groups of general cargo carriers ST are assigned. Even when loading the others Conveyor FEW with general cargo S must fill the gaps L2 or the empty cells LZ are taken into account in that after four tasks, the division distance t1 by one corresponding compensation amount Δt is increased.
Aus Figur 1 ist ersichtlich, daß das Stückgut S über die erste Fördereinrichtung FE1 unmittelbar in die Zellen Z des Flügelrades FR transportiert wird. Dieser Transport in das umlaufende Flügelrad FR wird durch eine Segmentierung von Flügelrad FR und erster Fördereinrichtung FE1 ermöglicht, zu deren Erläuterung zusätzlich auf die Figur 3 verwiesen wird. Bei der Segmentierung des auf einer Welle W umlaufenden Flügelrades FR weisen die einzelnen Flügel F in Richtung der Radachse RA gesehen mehrere hintereinander angeordnete Lücken L1 auf. Im Bereich dieser Lücken L1 sind auf der Welle W mit UR bezeichnete Umlenkräder drehbar angeordnet, um welche die mit SG1 bezeichneten Segmente der ersten Fördereinrichtung geführt sind. Die weitere Führung der endlos umlaufenden und beispielsweise durch Flachriemen gebildeten Segmente SG1 erfolgt über Spannrolle SR und Umlenkrollen URO1 und URO2. Über diese Umlenkrollen URO1 und URO2 sind auch die einzelnen Segmente der in Figur 1 lediglich durch eine strichpunktierte Linie angedeuteten weiteren Fördereinrichtung FEW geführt.From Figure 1 it can be seen that the piece goods S over the first Conveyor FE1 directly into the cells Z of the Impeller FR is transported. This transport in that revolving impeller FR is segmented by Impeller FR and first conveyor FE1 allows to the explanation of which is also referred to FIG. 3. When segmenting the impeller rotating on a shaft W. FR have the individual wings F in the direction of Wheel axis RA seen several gaps arranged one behind the other L1 on. In the area of these gaps L1 are on the shaft W with UR designated deflection wheels rotatably arranged around which the with SG1 designated segments of the first conveyor are led. The continued leadership of the endlessly circulating and for example, segments SG1 formed by flat belts via tension roller SR and deflection rollers URO1 and URO2. over these pulleys URO1 and URO2 are also the individual segments that in Figure 1 only by a dash-dotted Line indicated further conveyor FEW guided.
Der Antrieb des Flügelrades FR, der ersten Fördereinrichtung FE1 und der weiteren Fördereinrichtung FEW ist aus Figur 2 ersichtlich. Ein gemeinsamer Motor M treibt über ein erstes Antriebsrad AR1, einen strichpunktiert angedeuteten Riemen RI1 und ein Rad RD die Welle W (vergleiche Figur 3) des Flügelrades FR an. Außerdem treibt der Motor M über srichpunktiert dargestellte Riemen RI2 die Umlenkrolle URO1 an, welche ihrerseits über einen weiteren strichpunktiert dargestellten Riemen RI3 die Spannrolle SR antreibt. Durch diesen Antrieb über den gemeinsamen Motor M ist einerseits sichergestellt, daß die erste Fördereinrichtung FE1 und die weitere Fördereinrichtung FEW stets mit der gleichen Geschwindigkeit v1 angetrieben sind, während andererseits auch gewährleistet ist, daß das Verhältnis dieser Geschwindigkeit v1 zur Umfangsgeschwindigkeit u bzw. zur Winkelgeschwindigkeit des Flügelrades FR stets erhalten bleibt.The drive of the impeller FR, the first conveyor FE1 and the further conveyor FEW is from Figure 2 evident. A common motor M drives a first one Drive wheel AR1, a belt indicated by dash-dotted lines RI1 and a wheel RD the shaft W (see Figure 3) of the impeller FR on. In addition, the motor M drives by way of dotted lines Belt RI2 shown the guide roller URO1, which in turn over another shown in dash-dotted lines Belt RI3 drives the tension pulley SR. With this drive On the one hand, the common motor M ensures that the first conveyor FE1 and the further conveyor FEW always at the same speed v1 are driven, while on the other hand also guaranteed is that the ratio of this speed v1 to the peripheral speed u or the angular velocity of the Vane wheel FR is always preserved.
Die Führung der in Segmente SG2 unterteilten weiteren Fördereinrichtung FEW über die beiden Umlenkrollen URO1 und URO2 ermöglicht eine reibungslose Übergabe des Stückguts S (vergleiche Figur 1) an die erste Fördereinrichtung FE1. Von besonderem Vorteil ist dabei, daß die in der Zeichnung nicht näher dargestellten, zur Aufrechterhaltung des Teilungsabstandes t1 (vergleiche Figur 1) aber erforderlichen Querstollen der Segmente SG2 aus der gemeinsamen Förderebene der Fördereinrichtungen FE1 und FEW nach unten wegtauchen. Durch dieses Wegtauchen der Querstollen wird verhindert, daß diese das Stückgut S (vergleiche Figur 1) in die Zellen Z des Flügelrades FR stauchen und dabei gegebenenfalls beschädigen.The management of the further conveyor system divided into segments SG2 FEW via the two pulleys URO1 and URO2 enables a smooth transfer of the general cargo S (see FIG. 1) to the first conveyor FE1. From A particular advantage is that the not in the drawing shown in more detail, to maintain the separation distance t1 (cf. FIG. 1) but the necessary cross studs of the segments SG2 from the common funding level of the funding institutions Dip FE1 and FEW down. By this immersion of the cross tunnels prevents them the piece goods S (see Figure 1) in the cells Z of the impeller Compress FR and damage it if necessary.
Im dargestellten Ausführungsbeispiel kommt das Stückgut S (vergleiche Figur 1) mit einer Geschwindigkeit v1=2,15 m/s und mit einem Teilungsabstand t1=340 mm an. Der Teilungsabstand t1+Δt beträgt 510 mm. Das mit 20,8 Umdrehungen pro Minute umlaufende Flügelrad FR besitzt sechzehn Zellen Z und vier Leerzellen LZ. Die Umfangsteilung t2 des Flügelrades FR beträgt ungefähr 127 mm. Die Teilung t3 der mit einer Geschwindigkeit v3=0,625 m/s umlaufenden Stückgutträger ST beträgt 100 mm, während die Lücke L2 zwischen zwei Gruppen von Stückgutträgern ST jeweils 50 mm beträgt. Die in Figur 3 angedeutete Segmentierung von Flügelrad FR und erster Fördereinrichtung FE1 umfaßt insgesamt zehn Segmente des Flügelrades FR und neun Segmente SG1 der ersten Fördereinrichtung FE1.In the illustrated embodiment, the general cargo S comes (compare Figure 1) at a speed v1 = 2.15 m / s and with a pitch t1 = 340 mm. The division distance t1 + Δt is 510 mm. That with 20.8 revolutions per minute revolving impeller FR has sixteen cells Z and four empty cells LZ.
