Description
[0058] Further properties, features and advantages of the invention will become clear below by means of a description of preferred embodiments of the invention on the basis of the accompanying exemplary drawings, in which:

[0065]
[0066]
[0067] In the present description of exemplary embodiments of the present inventions, a powder filling device according to the invention is generally provided with the reference sign 1, which can be used in a plant 100 for the automated production of ammunition, also referred to as an ammunition assembly plant, which consists of a plurality of ammunition parts, in particular a case 119, an ignition element 127, a projectile 121 and a propellant charge.
[0068] With reference to
[0069] The slot 29 and the housing walls 31, 33, 35, 37 which delimit the slot 29 have not only the function of permitting the filling of the propellant charge powder 11 but likewise a guide function for a dispensing device 3, indicated by the reference symbol 3, for dispensing the propellant charge powder 11 into the dosing housing 5. The dispensing device 3 can be moved and can move along the slot 29 according to a translational reciprocating movement. In this case, the dispensing device 3 is positively guided during the movement, with the result that the metering can be carried out as reliably and accurately as possible. The dispensing device 3 comprises, for example, a funnel-like dispensing pre-container 39 which opens into a dispensing tube 41 which projects into the housing 5. For the optimized guidance of the dispensing device 3 along the filling movement, the dispensing device 3 furthermore has a guide plate 44 such as a guide adjuster which is attached to the dispensing device 3 in the region of the dispensing tube 41 and is arranged in this case such that the guide plate 44 rests on the guide surface 27 and thus co-determines the vertical position of the dispensing device 3. The dispensing device 3 can furthermore be connected to propellant charge powder filling, not illustrated, such as a silo 57 and/or a supply tube.
[0070] The filling operation, which will be explained in even more detail on the basis of the schematic illustrations 3 to 8, is carried out in principle as follows: firstly, the propellant charge powder 11 is introduced into the dosing housing 5 via the dispensing device 3 and intermediately stored. For the intermediate storage, firstly the housing structure of the dosing housing 5 is provided and secondly a metering buffer 9 which is mounted translationally, in particular in the manner of a drawer, movably relative to the dosing housing 5 and has a number of metering depressions 15 adapted to the number of ammunition cases 13, which metering buffer delimits the dosing space 23 downwards at least in sections during a filling operation, with the result that the propellant charge powder 11 is placed on the metering buffer 9, which is preferably configured as a planar plate with the metering depressions 15 configured as passage openings. After the intermediate storage of the propellant charge powder 11 by means of the metering buffer 9, the propellant charge powder 11 is dispensed into the ammunition cases 13 by a metering perforated plate 43 which is assigned to the metering buffer 9 and to which the plurality of ammunition cases 13 are docked.
[0071] The filling device 1 can furthermore have a collecting tray 45 which serves for collecting superfluous and unfilled propellant charge powder 11, which is indicated by the reference symbol 11. Via a pressing device 47, a pressing force can be applied to the metering buffer 9, with the result that in turn a resulting force is produced between metering buffer 9 and metering perforated plate 43 in order to keep the amount of superfluous propellant charge powder 11 as low as possible.
[0072]
[0073] The dispensing device 3 is filled with propellant charge powder 11 and faces the doser 7 and is arranged at a distance therefrom in such a way that a discharge opening 45 of the dispensing tube 41 is arranged at a vertical distance (a) from the doser 7 such that a self-locking effect occurs. This means that, owing to the narrow distance (a) between the discharge opening 45 and the doser 7 and the characteristic of the propellant charge powder 11, the propellant charge powder 11 itself blocks against a further flow out. As can be seen in
[0074] If the dispensing devices 3 now move between the two rest positions (
[0075] With reference to
[0076] After a filling operation of the dispensing device 3, the metering buffer 9 is finally moved, such that the metering depressions 15 are orientated in relation to the dosing space 23, in particular are arranged vertically below the dosing space 23, such that the propellant charge powder 11 moves into the metering depressions 15 exclusively under the influence of the low weight force and completely fills the latter (
[0077] The metering buffer 9 is subsequently moved back into the starting position illustrated in
[0078] An essential function of the device 1 according to the invention can be seen in
[0079]
[0080] In contrast to the preceding embodiment, the metering buffer 9 and, if appropriate, the metering perforated plate 43 (not illustrated) assigned thereto are designed as a rotary cycle table 51 which has a plurality of units or rows of metering depressions 15 which are distributed in the circumferential direction at an in particular uniform spacing (a) from one another, and wherein each unit or row is oriented in the radial direction with respect to the rotational direction R of the rotary cycle table 51. The dispensing device 3 can furthermore perform a translational movement in accordance with a reciprocating movement T in order to intermediately store the propellant charge powder 11 on the metering buffer 9. After a filling operation, the rotary cycle table 51 is rotated further in the rotational direction R, such that the units or rows of metering depressions 15 are supplied successively one after the other to the workpiece carriers 49 to be fed to the device 1, namely in a rotational position inclined by 45. The further basic principles and basic ideas of the device 1 according to the invention are also furthermore realized in the exemplary embodiment according to

[0083] Analogously to the embodiments with
[0084] The ammunition assembly plant 100 according to
[0085] The conveying device 113 for holding the plurality of ammunition parts and for transporting the plurality of ammunition parts from, to and/or between the plurality of production stations defines a closed circulating conveying track 29 which delimits an interior space 139 which is enclosed by the conveying track 137 and an exterior space 141 which is delimited therefrom.
