Description

Die Erfindung betrifft eine Förderbendwaage, bei der das Förderband von einem Schwingrahmen getragen wird. Erfindungsgemäß ist der Drehpunkt des Schwingrahmens horizontal so verschiebbar gelagert, daß er genau senkrecht unter den Schwerpunkt des auf dem Förderband der Wägevorrichtung ruhenden Materialkegels eingestellt werden kann. The invention relates to a conveyor belt weigher in which the conveyor belt is supported by a swing frame. According to the invention is the pivot point of the swing frame mounted horizontally so that it is exactly perpendicular under the center of gravity of the material cone resting on the conveyor belt of the weighing device can.

Bei den bekannten Förderbandw.aagen ist der Drehpunkt des Schwingrahmens fest angeordnet und liegt nicht senkrecht unter dem Schwerpunkt des auf dem Förderband liegenden Materialkegeis. In the known conveyor belt weighers, the pivot point is the oscillating frame fixed and is not perpendicular under the center of gravity of the on the conveyor belt lying material cone.

Dadurch werden zusätzliche positive oder negative Momente auf die W.aage übertragen, wodurch ungenaue Wägeergebnisse erzielt werden. Darüber hinaus wird insbesondere dann, wenn der Drehpunkt stark nach der Abwurfstelle des Bandes zu liegend angeordnet ist, das Einschwingen der Waage verzögert.This will add additional positive or negative moments to the Transfer weight, which results in inaccurate weighing results. Furthermore becomes especially when the pivot point is strongly after the release point of the tape is arranged too horizontally, the settling of the balance is delayed.

Bei dem verschiebbaren Schwingrahmen gemäß der Erfindung wird dieser Nachteil dadurch vermilden daß der Drehpunkt, beispielsweise mit Hilfe einer Schraubenspindel, so eingestellt werden kann, daß er genau senkrecht unter dem Schwerpunkt des Schüttkegels liegt und damit jede unerwünschte Beeinflussung der Wägeeinrichtung durch das aus einem Bunker austretende Gut aus geschaltet wird. In the sliding swing frame according to the invention this is Avoid the disadvantage that the pivot point, for example with the help of a screw spindle, can be adjusted so that it is exactly perpendicular under the center of gravity of the pouring cone and thus any undesirable influence on the weighing device by the goods escaping from a bunker are switched off.

In der Zeichnung ist im Aufriß eine Förderbandwaage mit verstellbarem Drehpunkt schematisch dargestellt. Auf dem als Waagebalken dienenden Schwingrahmen 1 mit den Umlenkrollen2 ist das Förderband 3 angeordnet. Der Schwingrahmen ist mit Hilfe der Schneiden 4 in den beweglichen Pfannen 5 gelagert, die mittels der Schraubenspindein 6 in der Horizontalen verschoben werden können. In the drawing is an elevation of a conveyor belt scale with adjustable Pivot point shown schematically. On the swing frame serving as a balance beam 1 with the pulleys 2, the conveyor belt 3 is arranged. The swing frame is with With the help of the cutting edges 4 stored in the movable pans 5, which by means of the screw spindles 6 can be moved horizontally.
