Stand der TechnikState of the art

Bei herkömmlichen Puiver-Dosiergeräten (Fig. 2) steht das gesamte Gewicht der Pulvermenge des Vorraisraumes (9) über dem Dosierraum (10) des Rotors (11).In conventional powder dosing devices (Fig. 2), the entire weight of the powder quantity in the pre-feed chamber ( 9) is above the dosing chamber (10) of the rotor (11).

Problemproblem

Bei jeder Pulver -Entnahme durch Drehen des Rotors (11 ) um ca. 180 Grad nimmt die Pulvermenge des Vorratsraumes (9) ab und somit nimmt auch die Dichte des Pulvers im Dosierraum (10) ab.Each time powder is removed by rotating the rotor (11) by approximately 180 degrees, the amount of powder in the storage chamber (9) decreases and thus the density of the powder in the dosing chamber (10) also decreases.

Daraus resultiert eine Abnahme des Gewichts des zu dosierenden Pulvers im Dosierraum (10).This results in a decrease in the weight of the powder to be dosed in the dosing chamber (10).

Da beim Wiederladen von Patronen auf 0,1 Grains (1 Grain = amerikanische Gewichtseinheit = 0,0648 Gramm) genau dosiert werden muß, können Schwankungen der Dosierungen zu Präzisionsschwankungen der wiedergeladenen Patronen führen.Since reloading cartridges requires precise dosing to 0.1 grains (1 grain = American unit of weight = 0.0648 grams), fluctuations in dosing can lead to precision fluctuations in the reloaded cartridges.

LösungSolution

Pulver - Dosiergerät (Fig. 1) mit 2 Rotoren (3) (6), die übereinander liegen und miteinander drehbar verbunden sind (4).Powder dosing device (Fig. 1) with 2 rotors (3) (6) which are placed one above the other and are connected to each other so that they can rotate (4).

Zwischen den Rotoren (3) (6) befindet sich ein Pufferraum (7).There is a buffer space between the rotors (3) (6) (7).

Durch Drehen eines Rotors (3) oder (6) wird der andere Rotor (3) oder (&dgr;) mitgedreht. Dadurch wird der Pufferraum (7) vom oberen Rotor (3) gefüllt und aus dem unteren Rotor (6) fäilt die Dosiermenge (5) heraus. Das Volumen des Pufferraums (7) ist größer als das Volumen des Dosierraums (5).By rotating one rotor (3) or (6), the other rotor (3) or (δ) is rotated as well. This fills the buffer chamber (7) from the upper rotor (3) and the dosing quantity (5) falls out of the lower rotor (6). The volume of the buffer chamber (7) is larger than the volume of the dosing chamber (5).

VorteileAdvantages

Auf dem Dosierraum (5) !astet nur die Menge des Pufferraums (7) und nicht des gesamten Vorratsraums (Fig. 2 / 9). Dadurch ergeben sich geringere Toleranzen im Dosierraum (5).Only the amount of the buffer space (7) is loaded onto the dosing chamber (5) and not the entire storage space (Fig. 2 / 9). This results in smaller tolerances in the dosing chamber (5).
