Description

Die Erfindung bezieht sich auf eine Weiche für eine Hängefördereinrichtung der im Oberbegriff von Anspruch 1 erläuterten Art.The invention relates to a switch for a overhead conveyor that in the preamble of claim 1 Art.

Eine derartige Weiche ist aus der DE-PS 30 48 384 bekannt. Die bekannte Weiche dient der Verbindung eines ersten Schienenendes wahlweise mit einem zweiten oder einem dritten Schienenende, die jeweils dem ersten Schienenende gegenüberliegen. Die Weiche hat zwei Weichenzungen. Eine der Weichenzungen ist über eine schräg verlaufende Drehachse mit dem zweiten Schienenende und die andere Weichenzunge über eine ebenfalls schräg verlaufende Drehachse mit dem dritten Schienenende drehbar verbunden. Die Weichenzungen können um die Drehachsen so verschwenkt werden, daß die freien Enden der Weichenzungen jeweils abwechselnd mit dem freien Ende des ersten Schienenendes fluchtend auszurichten sind. Beide Weichenzungen sind über eine Zugstange miteinander gekoppelt und werden in einem vorbestimmten Abstand zueinander gehalten, so daß beide Weichenzungen synchron bewegt werden können. Dabei wird sichergestellt, daß die zweite, sich außer Eingriff befindende Weichenzunge in sicherem Abstand zum ersten Schienenende gehalten wird, wenn die erste Weichenzunge mit dem ersten Schienenende ausgerichtet ist, so daß Hängezüge ungehindert durch die Weiche laufen können. Nachteilig an dieser Weiche ist es jedoch, daß sich beide Weichenzungen nicht nur in der gewollten Bewegung zum Umstellen der Weiche synchron bewegen, sondern auch dann, wenn unerwünschte Kräfte auf eine der Weichenzungen einwirken, beispielsweise versehentlich ein Zug aus der Gegenrichtung auf eine sich außer Eingriff mit dem ersten Schienenende befindenden Weichenzunge einfährt. Die dadurch auftretenden Kräfte übertragen sich voll auf die erste Weichenzunge, die dadurch aus ihrer ausgerichteten Position verschoben werden und den Absturz eines Hängeförderzuges bewirken kann. Auch können zu große auf die Lagerungen einwirkende Kräfte bleibende Verformungen verursachen.Such a switch is known from DE-PS 30 48 384. The known switch serves to connect one first rail end optionally with a second or a third rail end, each the first Opposite rail end. The switch has two switch tongues. One of the switch tongues is at an angle running axis of rotation with the second rail end and the other switch tongue over a likewise oblique one Rotation axis rotatable with the third rail end connected. The switch tongues can so about the axes of rotation be pivoted that the free ends of the switch tongues alternately with the free end of the first Align the end of the rail in alignment. Both switch tongues are connected to each other via a tie rod and are at a predetermined distance from each other held so that both switch tongues moved synchronously can be. This ensures that the second, disengaged switch tongue in safe Distance from the first rail end is kept, when the first switch tongue with the first rail end is aligned so that overhead trains unimpeded by the Switch can run. It is a disadvantage of this switch however, that both switch tongues are not only in the move the desired movement synchronously to change the switch, but also when unwanted forces arise one of the switch tongues, for example accidentally a move from the opposite direction to one itself Engagement with the first rail end Turnout tongue retracts. The resulting forces transfer fully to the first switch tongue, which thereby be moved from their aligned position and cause the overhead conveyor train to crash can. Excessively large ones can also act on the bearings Forces cause permanent deformations.

Der Erfindung liegt somit die Aufgabe zugrunde, die bekannte Weiche derart weiterzubilden, daß unerwünschte Belastungen der Weichenzungen abgefangen werden.The invention is therefore based on the object, the known Switch to develop such that undesirable Loads on the switch tongues are intercepted.

Die Aufgabe wird durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst.The task is characterized by the characteristic features of the Claim 1 solved.

Durch die erfindungsgemäße Ausgestaltung können beide Weichenzungen unter einer Belastung, die unterhalb der vorbestimmten Federkraft liegt, synchron bewegt werden. Greift jedoch eine Kraft an einem der Weichenzungen an, die über der vorbestimmten Federkraft liegt, so wird diese von der Feder absorbiert und führt nicht zwangsläufig zu einer Bewegung auch der anderen Weichenzunge.The configuration according to the invention allows both Switch tongues under a load below the predetermined spring force is moved synchronously. However, if a force is applied to one of the switch tongues, which is above the predetermined spring force, so this is absorbed by the spring and does not necessarily lead to move the other switch tongue too.

Zweckmäßigerweise wird die Federkraft gemäß Anspruch 2 derart auf das Gewicht der Weichenzungen und die Modalitäten der Weichen-Umstellung abgestimmt, daß beide Weichenzungen beim Umstellen der Weiche synchron bewegt werden.The spring force is expediently used according to claim 2 so on the weight of the switch tongues and the modalities the switch conversion matched that both switch tongues moved synchronously when switching the switch become.

Weitere, vorteilhafte Ausgestaltungen sind den Unteransprüchen 3 bis 7 zu entnehmen.Further advantageous embodiments are the subclaims 3 to 7.

Ein Ausführungsbeispiel der Erfindung wird nachfolgend anhand der einzigen Zeichnung näher erläutert, die eine perspektivische Draufsicht auf die erfindungsgemäße Weiche zeigt.An embodiment of the invention is as follows based on the single drawing, the one top perspective view of the switch according to the invention shows.

Die Fig. zeigt eine Weiche 1, die zwischen einem ersten Schienenende 2, einem zweiten, dem ersten Schienenende 2 gegenüberliegenden, zweiten Schienenende 3 und einem dritten Schienenende 4 angeordnet ist, das ebenfalls dem ersten Schienenende 2 gegenüberliegt. Im dargestellten Ausführungsbeispiel ist das zweite Schienenende 3 als geradlinige Verlängerung des ersten Schienenendes 2 ausgebildet und das dritte Schienenende 4 stellt eine seitliche Abzweigung dar.The figure shows a switch 1 which is between a first Rail end 2, a second, the first rail end 2 opposite, second rail end 3 and one third rail end 4 is arranged, which is also the first rail end 2 is opposite. In the illustrated Embodiment is the second rail end 3 as straight extension of the first rail end 2 is formed and the third rail end 4 represents a lateral one Branch.

Alle Schienenenden 2, 3 und 4, wie auch die sich an die Schienenenden anschließenden, nicht weiter dargestellten Schienen, haben ein dachförmiges Laufprofil, auf denen nicht dargestellte Hängefördermittel ablaufen können, die jeweils zwei durch einen unter der Schiene durchlaufenden Bügel miteinander verbundene Laufrollen haben. Die Schienenenden 2, 3 und 4 sind über gleichmäßig verteilte Abstandshalter 5 mit einem oberhalb der Schienenenden 2, 3, 4 angeordneten Traggerüst 6 verbunden, das einen ersten, rohrförmigen Trägerabschnitt 6a und einen zweiten rohrförmigen Trägerabschnitt 6b enthält, die über ein Rohrverbindungsstück 7 im rechten Winkel miteinander verbunden sind. Der erste Trägerabschnitt 6a verbindet das erste Schienenende 2 mit dem dritten Schienenende 3 in gerader Linie. Der zweite Trägerabschnitt 6b verbindet das zweite Schienenende 3 mit dem dritten Schienenende 4. Das Traggerüst 6 ist durch eine Querversteifung 6c ausgesteift, die wiederum durch einen der Abstandshalter 5 mit dem dritten Schienenende 4 verbunden ist. Das Traggerüst 6 ist als Teil des Traggerüstes für das gesamte Schienensystem der Hängefördereinrichtung ausgebildet, wobei beispielsweise der erste Trägerabschnitt 6a über die gesamte Länge der Schienen 2, 3 verlaufen, und im Bereich des dritten Schienenendes über ein Verbindungsrohrstück 8 mit einem weiteren Trägerabschnitt 9 entlang der Schiene des Schienenendes 4 verbunden sein kann.All rail ends 2, 3 and 4, as well as the ones on the Connecting rail ends, not shown Rails have a roof-shaped running profile on which Suspended funds, not shown, can run off, the two each by one passing under the rail Brackets have interconnected castors. The rail ends 2, 3 and 4 are evenly distributed Spacer 5 with one above the rail ends 2, 3, 4 arranged support structure 6 connected, the a first tubular support section 6a and one includes second tubular support portion 6b which via a pipe connector 7 at right angles to each other are connected. The first beam section 6a connects the first rail end 2 to the third Rail end 3 in a straight line. The second beam section 6b connects the second rail end 3 with the third rail end 4. The support structure 6 is through a Cross stiffener 6c stiffened by a the spacer 5 is connected to the third rail end 4 is. The support structure 6 is part of the support structure for the entire rail system of the overhead conveyor trained, for example the first Carrier section 6a over the entire length of the rails 2, 3 run, and in the area of the third rail end via a connecting pipe piece 8 with a further support section 9 along the rail of the rail end 4 can be connected.

Am Traggerüst 6 ist in der Nähe des freien Endes des zweiten Schienenendes 3 über ein schräg gestelltes Drehlager 10 ein Ende einer erste, geradlinigen Weichenzunge 11 derart drehbar gelagert, daß das dem Drehlager 10 zugewandte Ende der Weichenzunge 11 mit dem zweiten Schienenende 3 in Verbindung steht, und das freie Ende lla der Weichenzunge 11 aus der in der Zeichnung durchgezogen gezeichneten Verbindungsposition zum Verbinden der Schienenenden 2 und 3 in eine gestrichelt gezeichnete, unwirksame Position verschwenkt werden kann, in der das freie Ende lla der Weichenzunge 11 zum ersten Schienenende 2 einen derartigen Abstand aufweist, daß es kein Hindernis für einlaufende Züge bildet.On the support structure 6 is near the free end of the second rail end 3 via an inclined pivot bearing 10 one end of a first straight turnout tongue 11 rotatably mounted so that the pivot bearing 10 facing End of the switch tongue 11 with the second rail end 3 communicates, and the free end lla the switch tongue 11 pulled through in the drawing drawn connection position for connecting the Rail ends 2 and 3 in a dashed line, ineffective position can be pivoted in the free end lla of the switch tongue 11 to the first rail end 2 is such a distance that there is no Forms an obstacle to incoming trains.

Eine zweite, gekrümmte Weichenzunge 12 ist in gleicher Weise über ein schräg gestelltes Drehlager 13 derart mit dem dritten Schienenende 4 verbunden, daß die zweite Weichenzunge 12 mit ihrem einen Ende fluchtend mit dem dritten Schienenende 4 ausgerichtet bleibt und das zweite, freie Ende 12a der Weichenzunge 12 aus der in der Zeichnung durchgezogen gezeichneten, unwirksamen Stellung in die gestrichelt gezeichnete, wirksame Stellung verschwenkt werden kann, in der das freie Ende 12a mit dem ersten Schienenende 12 fluchtet.A second, curved switch tongue 12 is in the same Way with an inclined pivot bearing 13 connected to the third rail end 4 that the second Switch tongue 12 with one end aligned with the third rail end 4 remains aligned and the second, free end 12a of the switch tongue 12 from the in the Drawing drawn, ineffective position pivoted into the effective position shown in dashed lines can be in which the free end 12a with the first rail end 12 is aligned.

Die Schrägstellung der Drehachsen beider Drehlager 10, 13 ist so gewählt, daß die freien Enden lla, 12a der beiden Weichenzungen 11, 12 im wesentlichen V-förmig zusammenlaufen und jeweils in ihrer unwirksamen Stellung schräg oberhalb des ersten Schienenendes 2 liegen und beim Stellen der Weiche auf ein am ersten Schienenende 2 angeordnetes, gegen seitliche Verschiebung sicherndes, nicht gezeichnetes Auflager abgesenkt werden.The inclination of the axes of rotation of both pivot bearings 10, 13 is chosen so that the free ends lla, 12a of the two switch tongues 11, 12 converge essentially in a V-shape and each in their ineffective position lie diagonally above the first rail end 2 and when placing the switch on one at the first rail end 2 arranged, against lateral displacement, support not shown can be lowered.

In der Nähe der Drehlager 10, 13 und zwischen den Drehlagern 10, 13 und den freien Enden 11a, 12a sind beide Weichenzungen 11, 12 für eine gemeinsame Bewegung über ein Federelement in Form einer Druckstange 14 miteinander gekoppelt. Die Druckstange 14 besteht aus zwei teleskopisch gegen die Federkraft einer im Inneren der Druckstange 14 angeordneten, nicht gezeichneten Druckfeder auszieh- und ineinanderschiebbaren Teilen 14a, 14b. Die freien Enden der Druckstange 14 sind über jeweils ein Kugelgelenk 15 (nur eines gezeichnet) mit einer Hebelplatte 16 (ebenfalls nur eine gezeichnet) schwenkbar verbunden. Die Hebelplatten 16 sind über einen der Abstandshalter 5 mit jeweils einer Weichenzunge 11, 12 starr verbunden. An einer der Hebelplatten 16 greift ein Stellantrieb 17 zum Umstellen der Weiche an. Der Stellantrieb 17 ist auf einer Trägerplatte 18 befestigt, die wiederum am Traggerüst 6 fest angeordnet ist, und betätigt über ein Stellglied 19 und ein Kugelgelenk 20 die Hebelplatte 16.Near the pivot bearings 10, 13 and between the pivot bearings 10, 13 and the free ends 11a, 12a are both Switch tongues 11, 12 for a joint movement over a spring element in the form of a push rod 14 with each other coupled. The push rod 14 consists of two telescopic against the spring force of one inside the Push rod 14 arranged, not shown compression spring extendable and telescopic parts 14a, 14b. The free ends of the push rod 14 are over each a ball joint 15 (only one drawn) with a lever plate 16 (also only one drawn) swiveling connected. The lever plates 16 are over one of the spacers 5, each with a switch tongue 11, 12 rigidly connected. One of the lever plates 16 engages Actuator 17 to change the switch. The actuator 17 is attached to a carrier plate 18 which is in turn arranged on the supporting structure 6, and actuated via an actuator 19 and a ball joint 20 Lever plate 16.

Die Federkraft der Druckfeder in der Druckstange 14 ist so auf das Gewicht der Weidenzungen 11, 12 und die Stellkräfte der Weiche abgestimmt, daß bei der Betätigung des Stellantriebes 17 beide Weichenzungen synchron bewegt werden und damit den Abstand ihrer freien Enden lla, 12a beibehalten. Wenn somit das freie Ende 12a der zweiten Weichenzungen 12 aus der in der Zeichnung dargestellten, unwirksamen Position in eine Position bewegt wird, in der das freie Ende 12a mit dem ersten Schienenende 2 fluchtet, so bewegt sich gleichzeitig das freie Ende lla in die in der Zeichnung gestrichelt gezeichnete Position, ohne daß sich ihr Abstand zueinander verändert. Wirkt jedoch eine zusätzliche Kraft auf eine der beiden Weichenzungen, die die Umstellkraft und die auf die Umstellkraft abgestimmte Federkraft übersteigt, beispielsweise indem ein Hängeförderzug versehentlich vom dritten Schienenende 4 auf die Weichenzungen 12 gelangt, so kann sich die Weichenzunge 12 unter Verkürzung der Druckstange 14 und gegen die Kraft der darin enthaltenen Druckfeder etwas nach unten bewegen, ohne daß das freie Ende lla der Weichenzunge 11 aus dem Auflager und somit aus seiner fluchtenden Ausrichtung mit dem ersten Schienenende 2 gedrückt wird. Dadurch werden jedoch auch die auf die Drehlager 10, 13 einwirkenden Kräfte abgepuffert.The spring force of the compression spring in the push rod 14 is so on the weight of the willow tongues 11, 12 and the Actuating forces of the switch matched that when actuated of the actuator 17 both switch tongues synchronously be moved and thus the distance of their free ends lla, 12a maintained. Thus, if the free end 12a the second switch tongues 12 from that in the drawing shown, ineffective position moved to a position in which the free end 12a with the first Rail end 2 is aligned, so that moves at the same time free end lla in the dashed line in the drawing Position without changing their distance from each other changed. However, an additional force acts on one of the two switch tongues, the changeover force and the spring force matched to the changeover force, for example by accidentally pulling a overhead conveyor reaches the switch tongues 12 from the third rail end 4, so the switch tongue 12 can shorten the push rod 14 and against the force of the contained therein Move the compression spring down a little without it free end lla of the switch tongue 11 from the support and thus from its aligned alignment with the first Rail end 2 is pressed. However, this will also the forces acting on the rotary bearings 10, 13 are buffered.

In Abwandlung des beschriebenen und gezeichneten Ausführungsbeispiels kann die Vorspannung der Druckfeder der Druckstange 14 beispielsweise über eine Schraubverbindung im Bereich des Kugelkopfes 15 verändert werden. Es ist weiterhin möglich, die Druckstange 14 nur an einer Seite über ein Kugelgelenk mit der jeweiligen Weichenzunge zu verbinden. Anstelle der Druckstange kann auch eine freiliegende Druckfeder verwendet werden. Bei einer anderen Lage der Drehachsen der Drehlager 10, 13 und einer damit verbundenen anderen Bewegungsrichtung der Weichenzungen 11, 12 kann es unter Umständen erforderlich sein, zwischen den beiden Weichenzungen eine Zugstange und eine Zugfeder vorzusehen.In a modification of the described and drawn embodiment can bias the compression spring the push rod 14, for example via a screw connection be changed in the region of the ball head 15. It is also possible to only push the push rod 14 on one side over a ball joint with the respective Connect switch tongue. Instead of the push rod an exposed compression spring can also be used. At a different position of the axes of rotation of the pivot bearings 10, 13 and a related other direction of movement the switch tongues 11, 12 may be necessary under certain circumstances be one between the two switch tongues Tension rod and a tension spring to be provided.
