Abstract

The belt separates under the coupling (2) joined to the loaded stringer (4). The free end of the empty stringer (6) is suspended from the coupling by at least one spring (3). The rigidity of the spring is less than that of the empty stringer in the bottommost position of the load. A coupling (1) joined to the end of the empty stringer is movably guided in relation to the coupling (2) joined to the loaded stringer, in the direction of the stringer. The tension of the belt is at least partly adjusted by the spring. The spring is a piece of belt of lesser rigidity.

Description

Die Erfindung betrifft einen Riementrieb mit einem mit dem Riemen verbundenen Koppelstück zur Abnahme einer Kraft, vorzugsweise einen Zahnriementrieb für Senkrechtförderer.The invention relates to a belt drive with a Belt-connected coupling piece for taking off a force, preferably a toothed belt drive for vertical conveyors.

Regalbediengeräte und Senkrechtförderer mit Zahnriemengetrieben sind bekannt. Durch die Verwendung der Zahnriemen können größere Lasten in einfacher Weise bewegt und positioniert werden. Die Last ruht auf einem Koppelstück, das mit dem Zahnriemen verbunden ist. Durch die Last wird der Lasttrum (der Zahnriementeil oberhalb der Koppelstelle bzw. der zwischen Koppelstelle und Antriebsrad befindliche Zahnriementeil) gespannt und der Leertrum (der Zahnriementeil unterhalb der Koppelstelle) entspannt.Storage and retrieval machines and vertical conveyors with toothed belt drives are known. By using the toothed belt larger Loads can be easily moved and positioned. The Load rests on a coupling piece that is connected to the toothed belt connected is. The load strand (the Timing belt part above the coupling point or between Coupling point and drive wheel toothed belt part) tensioned and the empty strand (the timing belt part below the Coupling point) relaxed.

Bei konstanter Last ändert sich die Spannung im Leertrum mit der Änderung des Längenverhältnisses von Leer- zu Lasttrum. Je kleiner dieses Längenverhältnis ist, umso geringer wird die Kraft im Leertrum. Die verbleibende Leertrumkraft ist vom Wert der Vorspannkraft abhängig. Wenn die Vorspannkraft zu gering ist, entsteht im Leertrum ein kraftloser Zustand. Im kraftlosen Zustand des Leertrums wird die Riemenverzahnung aus der Umlenkrolle gedrückt. Das führt zu Betriebsstörungen und senkt die Lebensdauer des Zahnriemens.With constant load, the tension in the empty strand changes with the Change of the length ratio from empty to load strand. Each the smaller this aspect ratio, the lower the Strength in the empty strand. The remaining empty strand force is of value dependent on the preload. If the preload is too low an empty state is created in the empty strand. In the weak The belt serration from the Deflection roller pressed. This leads to malfunctions and lowers the life of the timing belt.

Zur Vermeidung derartiger Störungen wird bei industriellen Anwendungen mit hohen Vorspannkräften oder/und zusätzlichen Andruckrollen gearbeitet. Die Folge sind extreme Belastungen der Scheibenlagerungen, erhöhte Deformation der Riemenverzahnung und starke Flankenreibung zwischen Riemen und Scheibe, welche letztlich auch die Lebensdauer des Getriebes herabsetzen. Die große Lagerreibung durch hohe Vorspannkräfte senkt den Wirkungsgrad des Getriebes und führt zu erheblichen Energieverlusten. To avoid such disruptions in industrial Applications with high preload forces and / or additional Pinch rollers worked. The result is extreme loads on the Pulley bearings, increased deformation of the belt teeth and strong flank friction between belt and pulley, which ultimately also reduce the service life of the transmission. The high bearing friction due to high preload forces lowers the Efficiency of the transmission and leads to significant Energy losses.  

Nach DE-OS 38 08 479 sind in den Zahnriemen Stahldrähte eingelagert. Diese Zahnriemen können hohe Kräfte bei nur geringen Dehnungen aufnehmen. Es sind allerdings Sonderfertigungen erforderlich.According to DE-OS 38 08 479 there are steel wires in the toothed belt stored. These timing belts can withstand high forces only absorb small strains. However, there are Special productions required.

Aufgabe der Erfindung ist es, das Absinken der Vorspannung im Leertrum unter der Last zu verringern.The object of the invention is to reduce the bias in Reduce empty span under the load.

Erfindungsgemäß wird die Aufgabe mit den in den Ansprüchen genannten und im Ausführungsbeispiel näher erläuterten Mitteln gelöst.According to the invention the task with the in the claims mentioned means and explained in more detail in the embodiment solved.

Durch die Feder zwischen Last- und Leertrum wird erreicht, daß unter der Last nicht nur die Vorspannung im Leertrum gesenkt wird, sondern auch die in der Feder. Die Dehnung des Lasttrums unter der Last wird damit auch von der Feder und nicht nur vom Leertrum aufgenommen, und zwar umso mehr, je geringer die Federsteifigkeit ist.The spring between the load and empty strand ensures that not only reduced the pretension in the empty strand under the load will, but also in the pen. The stretching of the load strand under the load is also from the spring and not only from Empty strand recorded, and the more the lower the Is spring stiffness.

Durch die erfindungsgemäße Lösung kann die Vorspannung des Zahnriemens und damit die Belastung des Getriebes wesentlich gesenkt werden. Zusätzliche Andruckrollen sind nicht erforderlich.By the solution according to the invention, the bias of the Timing belt and thus the load on the gearbox significantly be lowered. Additional pressure rollers are not required.

Die Lösung ist sowohl für Senkrechtförderer als auch allgemein für Linearantriebe, die bevorzugt in einer Richtung belastet sind, anwendbar.The solution is both for vertical conveyors and in general for linear drives that are preferably loaded in one direction are applicable.

Im Ausführungsbeispiel ist am Lasttrum 4 ein Koppelstück 2 befestigt. An diesem Koppelstück 2 greift eine Last mit der Masse m an.In the exemplary embodiment, a coupling piece 2 is attached to the load strand 4 . A load with the mass m acts on this coupling piece 2 .

Das Ende des Leertrums 6 ist in einem gegenüber dem festen Koppelstück 2 beweglichen Koppelstück 1 eingespannt. Das bewegliche Koppelstück 1 ist in dem festen Koppelstück 2 mit zwei Stangen 5 in Trumrichtung verschiebbar geführt. Beide Koppelstücke sind mit den Federn 3 gegen die Vorspannung des Zahnriemens miteinander verbunden. Mit den Muttern 7 ist über die Federn 3 die Vorspannung im Zahnriemengetriebe zumindest teilweise einstellbar.The end of the empty run 6 is clamped in a coupling piece 1 that is movable relative to the fixed coupling piece 2 . The movable coupling piece 1 is guided in the fixed coupling piece 2 with two rods 5 displaceable in the strand direction. Both coupling pieces are connected to each other with the springs 3 against the pretension of the toothed belt. With the nuts 7 , the bias in the toothed belt transmission can be at least partially adjusted via the springs 3 .
