Abstract
Description
Die Erfindung betrifft einen Lagerlift mit einem zwischen sich gegenüberliegenden Regalsäulen angeordneten, zum Ein- und Auslagern von Lagergutträgern dienenden Vertikalförderer, in den die Vertikalbewegungen durch einen Zahnriemen eingeleitet werden, der eine am unteren Ende des Lagerliftes angeordnete Antriebsriemenscheibe und eine am oberen Ende des Lagerliftes angeordnete Umlenkriemenscheibe passiert.The invention relates to a storage lift with one opposite between them rack columns arranged, for the storage and retrieval of storage goods carriers Vertical conveyor, in which the vertical movements are initiated by a toothed belt the drive pulley arranged at the lower end of the bearing lift and a deflection pulley arranged at the upper end of the storage lift happens.
Der grundsätzliche Aufbau eines derartigen Lagerliftes
ist beispielsweise aus der
Die Verwendung eines Zahnriemens zum Einleiten der Vertikalbewegungen in den auch als Extraktor bezeichneten Vertikalförderer bietet gegenüber der Verwendung einer Rollenkette als Antriebsmittel den Vorteil eines ruhigeren Laufes. Die gegenüber Rollenketten größere Elastizität des Zahnriemens kann jedoch zu Problemen bei einem Notstopp des Vertikalförderers im unteren Bereich des Lagerliftes führen. In einem solchen Fall längt sich der die Last tragende längere Abschnitt des Zahnriemens um einen vom Bremsmoment des Antriebsmotors abhängigen Betrag, der einen spürbaren Abfall der Vorspannung im unbelasteten, kürzeren Abschnitt des Zahnriemens bewirkt und dies mit der Folge, daß es zu einem Überspringen von Zähnen der Antriebsriemenscheibe durch den Zahnriemen kommt.The use of a timing belt to initiate the vertical movements in the so-called extractor vertical conveyor offers opposite the advantage of using a roller chain as a drive means a smoother run. The greater elasticity of the timing belt compared to roller chains can cause problems with an emergency stop of the vertical conveyor lead in the lower area of the storage lift. In such a case lengthens the longer one carrying the load Section of the toothed belt by an amount dependent on the braking torque of the drive motor, one noticeable The preload drops in the unloaded, shorter section of the toothed belt causes and this with the result that there is a skipping of teeth the drive pulley comes through the toothed belt.
Der Erfindung liegt die Aufgabe zugrunde, das vorstehend geschilderte Überspringen von Zähnen der Antriebsriemenscheibe durch den Zahnriemen zu unterbinden. Gelöst wird diese Aufgabe bei einem Lagerlift der in Betracht gezogenen Gattung erfindungsgemäß dadurch, daß der die Umlenkriemenscheibe passierende, die Antriebsriemenscheibe mit dem Vertikalförderer verbindende längere Abschnitt des Zahnriemens mit dessen den Vertikalförderer direkt mit der Antriebsriemenscheibe verbindenden kürzeren Abschnitt unter Zwischenschaltung einer den Einfluß von Dehnungen des längeren Abschnittes auf den kürzeren Abschnitt kompensierenden Feder verbunden ist.The invention has for its object that skipping described above of teeth to prevent the drive pulley by the toothed belt. Is solved this task according to the invention in the case of a storage lift of the type under consideration, that the the drive pulley passing through the deflection pulley the vertical conveyor connecting longer Section of the toothed belt with which the vertical conveyor directly with the drive pulley connecting shorter section with the interposition of a the influence of Stretches of the longer Section on the shorter Section compensating spring is connected.
Weitere Merkmale und Einzelheiten der Erfindung ergeben sich aus den Unteransprüchen und der nachstehenden Beschreibung einer in den beigefügten Zeichnungen dargestellten Ausführungsform der Erfindung.Other features and details the invention result from the dependent claims and the following Description of one in the attached Drawings shown embodiment of the Invention.
