US 11,938,756 B2 · Granular material metering device and method

Abstract

A method for controlling a device for metering granular material and a metering device for metering granular material comprises a feed for the granular material from a container into a metering chamber. A metering piston can be actuated by a control device such that a gap between the feed and the metering chamber is opened by a predefined first distance and a second distance which is greater than the first distance. At least one sensor is arranged in a delivery line leading away from the metering chamber and is connected to the control device so that the metering piston can be actuated for a predefined duration such that the gap between the feed for the granular material and the metering chamber can be opened by the second distance if a blockage of the granular material is detected by the at least one sensor, so that the blockage is dispersed.

Dependent claims

A method, comprising:

actuating a metering piston of a metering device to form a gap between a feed of the metering device and a metering chamber of the metering device, the feed configured to receive granular material from a container, the gap configured to permit the granular material to flow from the feed to the metering chamber;
detecting a blockage of the granular material with at least one optical sensor arranged in a delivery line leading away from the metering chamber;
and
responsive to detecting the blockage, actuating the metering piston to enlarge the gap between the feed and the metering chamber to disperse the blockage.
