Abstract
Description
Die Erfindung betrifft eine Bandwaage für eine Maschine der tabakverarbeitenden Industrie, mit einem Förderband und einer unterhalb des Förderbandes angeordneten Wiegeeinrichtung zur Messung des Gewichts eines auf dem Förderband transportierten Produkts.The The invention relates to a belt scale for a machine of tobacco processing Industrial, with a conveyor belt and one below the conveyor belt arranged weighing device for measuring the weight of a the conveyor belt transported product.
Bandwaagen finden beispielsweise bei der Tabakzuführung zu einem Tabaktrockner oder zur dosierten Beimischung von Komponenten Verwendung. Das Meßergebnis ist in der Praxis unter anderem vom Reibungswert zwischen dem Förderband und der Wiegeeinrichtung abhängig, der wiederum Schwankungen abhängig von der Bandgeschwindigkeit, der Bandabnutzung sowie von Umgebungseinflüssen wie der Temperatur, der Luftfeuchtigkeit und dem Luftdruck unterworfen ist. Diese Einflüsse wirken sich nachteilig auf die Meßgenauigkeit aus. Es ist bekannt, den Reibungswert zwischen Förderband und Wiegeeinrichtung durch Verwendung von frei rotierenden Rollen an der Wiegeeinrichtung zu reduzieren. Dabei wirken sich jedoch Abweichungen im Rundlauf der Rollen sowie Lagerreibungen negativ auf die Meßgenauigkeit aus.belt scales find, for example, the tobacco feed to a tobacco dryer or for metered admixture of components use. The measurement result is in practice, inter alia, the coefficient of friction between the conveyor belt and dependent on the weighing device, which in turn depends on fluctuations on tape speed, tape wear and environmental influences such as the temperature, the humidity and the air pressure is. These influences adversely affect the accuracy of measurement. It is known, the coefficient of friction between conveyor belt and Weighing device by using freely rotating rollers to reduce the weighing device. However, deviations have an effect in the concentricity of the rollers and bearing friction negative on the accuracy out.
Die Aufgabe der Erfindung besteht darin, die Meßgenauigkeit einer Bandwaage insbesondere gegenüber Einflüssen wie der Bandgeschwindigkeit, der Bandabnutzung und Umgebungseinflüssen zu verbessern.The The object of the invention is the accuracy of a belt scale especially opposite influences how to improve the tape speed, the tape wear and environmental influences.
Die Erfindung sieht zur Lösung dieser Aufgabe insbesondere vor, daß zwischen dem Förderband und der Wiegeeinrichtung ein separates, mit der Bandwaage unabhängig von der Wiegeeinrichtung verbundenes Zwischenelement zur Aufnahme der von dem Förderband ausgeübten Reibungskraft angeordnet ist. Das Zwischenelement nimmt die von dem Förderband ausgeübte Reibungskraft auf und leitet sie unter Umgehung der Wiegeeinrichtung an die Bandwaage bzw. ein Bandwaagengestell ab. Auf diese Weise wird ein Einfluß der Reibungskraft auf die Wiegeeinrichtung vermieden, so daß sich Schwankungen des Reibwertes zwischen Förderband und Wiegeeinrichtung bzw. Zwischenelement nicht auf das Meßergebnis auswirken.The Invention looks to the solution this task in particular, that between the conveyor belt and the weighing device a separate, with the belt weigher regardless of the weighing device connected intermediate element for receiving the the conveyor belt exerted Friction force is arranged. The intermediate element takes the of the conveyor belt practiced Frictional force on and passes them bypassing the weighing device to the belt scale or a belt scale frame from. In this way becomes an influence of Frictional force on the weighing device avoided, causing fluctuations the coefficient of friction between conveyor belt and weighing device or intermediate element not on the measurement result impact.
Das Zwischenelement überträgt die vom Produkt auf das Förderband ausgeübte Gewichtskraft auf die Wiegeeinrichtung. Auf den eigentlichen Meßvorgang soll das Zwischenelement dabei einen möglichst geringen Einfluß nehmen. Daher übt das Zwischenelement in der Meßrichtung eine im Verhältnis zur Meßkraft geringe, vorzugsweise vernachlässigbare Kraft aus. Gering heißt höchstens 20 %, vorzugsweise höchstens 10 %, weiter vorzugsweise höchstens 5 % der zu messenden Gewichtskraft. Vernachlässigbar heißt weniger als 2 %, vorzugsweise weniger als 1 % der zu messenden Gewichtskraft. Dies kann beispielsweise durch eine Gewichtsentlastungseinrichtung für das Zwischenelement oder sehr geringes Eigengewicht des Zwischenelements erreicht werden. Das Zwischenelement kann im wesentlichen kräftefrei gelagert oder geführt sein. Die Meßrichtung ist die Richtung der auf die Wiegeeinrichtung wirkenden Kraft infolge des Gewichts des Produkts, bei horizontalem Förderband also die Vertikalrichtung.The Intermediate element transmits the product on the conveyor belt practiced Weight on the weighing device. On the actual measuring process the intermediate element should take as little influence as possible. Therefore exercises the intermediate element in the measuring direction one in proportion to the measuring force low, preferably negligible Power out. Low means at the most 20%, preferably at most 10%, more preferably at most 5% of the weight to be measured. Negligible means less than 2%, preferably less than 1% of the weight to be measured. This can be, for example by a weight relief device for the intermediate element or very low weight of the intermediate element can be achieved. The intermediate element can be stored or guided substantially free of forces. The measuring direction is the direction of the force acting on the weighing device due the weight of the product, in horizontal conveyor belt so the vertical direction.
Das Zwischenelement kann aus Stahlblech, Textilmaterial, Leder, Kunststoff, Papier, Gurtmaterial, Kunststoff-beschichtetem Material oder einem anderen geeigneten Material bestehen.The Intermediate element can be made of sheet steel, textile material, leather, plastic, Paper, webbing, plastic-coated material or one other suitable material.
