The invention relates to a method for controlling a device (1) for metering granular material (2) and a metering device (1) for metering granular material (2), comprising a feed (9) for the granular material (2) from a container (5) into a metering chamber (6), wherein a metering piston (7) can be actuated by a control device (16) in such a way that a gap (8) between the feed (9) for the granular material (2) and the metering chamber (6) can be opened by a predefined first distance (d1) and a second distance ((d2), which is greater than the first distance (d1). According to the invention, at least one sensor (10) is arranged in a delivery line (11) leading away from the metering chamber (6) and is connected to the control device (16), such that the metering piston (7) can be actuated for a predefined duration ([delta]t) in such a way that the gap (8) between the feed (9) for the granular material (2) and the metering chamber (6) can be opened by the second distance (d2), if a blockage of the granular material (2) is detected by the at least one sensor (10), so that the blockage is dispersed.

    本发明涉及一种用于控制用于计量粒状材料(2)的装置(1)的方法和一种用于计量粒状材料(2)的计量装置(1),其包括从容器(5)进入计量室(6)中的粒状材料(2)的进给部(9),其中计量活塞(7)可以由控制装置(16)以这样的方式致动,使得粒状材料(2)的进给部(9)和计量室(6)之间的间隙(8)打开预定的第一距离(d1)和大于第一距离(d1)的第二距离(d2)。根据本发明,至少一个传感器(10)布置在远离计量室(6)的输送管线(11)中并连接到控制装置(16),使得计量活塞(7)以这样的方式被致动预定的持续时间(Δt),使得如果由至少一个传感器(10)检测到粒状材料(2)的堵塞,则将粒状材料(2)的进给部(9)和计量室(6)之间的间隙(8)打开第二距离(d2),使得消除堵塞。
