Definitions

  • the invention relates to a propellant charge portioner according to the features specified in the preamble of claim 1.
  • module-like propellant charge elements are pushed one after the other from a storage position into a charging cradle by a hydraulically actuated shifting device and then swiveled up from the charging cradle into a position ready for insertion behind the weapon barrel for the loading process of a barrel weapon.
  • the propellant charge modules which can be introduced one after the other in the longitudinal direction disadvantageously result in a comparatively large loading time of the propellant charge shell which opposes an increase in cadence.
  • DE 34 37 588 A1 discloses a charging arm of a tubular weapon which is fixedly mounted about a shield pin and which, on the one hand, can also accommodate propellant charge modules in different numbers directly from a propellant charge magazine in the axial direction and on the other hand in the transverse direction.
  • the supply of the propellant charge modules is determined here by the shape of the propellant charge magazine, an embodiment of the propellant charge magazine as a shaft magazine with transverse division requiring a lever mechanism integrated within the magazine, as a result of which the propellant charge modules located in the magazine shafts arranged transversely to the charging cradle can be conveyed directly into the charging cradle.
  • the propellant charging modules For feeding the in the Propellant charge modules located laterally next to the charging cradle in the charging cradle, however, the propellant charging modules must also be successively moved into the charging cradle.
  • the object of the invention is to provide a propellant charge portioner which, regardless of the magazine, allows a quantity of propellant charge modules which is always simultaneously variable to be fed into a charging cradle.
  • the portioner according to the invention forms an automatic transfer station for the propellant charge modules, which transfer station is detached from a propellant charge magazine and which advantageously take up propellant charge modules from various types of magazine, for example drum, tape, chain, bulk goods or shaft magazines, and at the same time a propellant charge set consisting of one or n propellant charge modules can pass.
  • each propellant charge module located in the portioner can be individually driven individually by a cross slide and thus a variable-quantity propellant charge set can be transversely displaced in the charging cradle behind the weapon barrel for further transport.
  • a constant, short loading time for the charging cradle is achieved, independent of magazine-specific feed speeds of the propellant charge modules.
  • the portioners 10, 12 shown in FIGS. 1 and 2 are arranged opposite to a transport device 18 which is preferably operatively connected to a propellant charge magazine, not shown, in the direction of displacement 16 of the propellant charge modules 14 and a charging tray 20 which can be pivoted about a transfer arm 42.
  • the transfer arm 42 is rotatably mounted about a shield pin axis 44 of a weapon barrel (not shown), while the portioner 10, 12 and the propellant charge magazine can be attached directly to a tank tower (not shown).
  • the portioners 10, 12 shown each contain a housing 28, 30 which is U-shaped in the longitudinal direction 16 for receiving the propellant charge modules 14 and is open on the side 32 facing the charging cradle 20.
  • the portioner 10 shown in FIG. 1 contains on the back of its housing 28 a plurality of sliders 26 which can be moved in the transverse direction 24, one slider in each case being assigned to a propellant charge module 14 and thereby different amounts of propellant charge 15 varying in length at the same time and briefly and thus determining the cadence the charging cradle 20 can be supplied.
  • a drive 34 for example a hydraulic piston-cylinder unit
  • the individually drivable Sliders 26 are additionally stably supported in a bearing 27 outside the portioner 10.
  • a slide surface 29 which is adapted to the length and diameter of a propellant charge module 14 is arranged for a gentle transverse displacement of the propellant charge modules 14.
  • the propellant charge modules 14 are fed to the portioner 10 on one side in the axial direction 16, for which purpose the device 18 contains a propellant charge collecting channel 19 which is not shown in operative connection with the propellant charge magazine and a slide 38 for displacing the propellant charge modules 14 taken over from the magazine in the collecting channel 19.
  • This slide 38 is arranged transversely to the collecting trough 19 and encloses on the outer side as a nut a threaded spindle 40 belonging to a screw drive.
  • This threaded spindle is connected in a manner not shown to a geared motor and a brake, which advantageously results in a high space-saving and robust construction Positioning accuracy of the propellant charge modules when feeding into the positioner 10, 12 can be achieved.
  • the threaded spindle 40 is preferably rotatably mounted over a wall 41 of the magazine (not shown), while the slide 38 is guided in a longitudinal groove 35 in the wall 41.
  • a partition door 36 is mounted in the wall 41 transversely to the direction of displacement 16 of the propellant charge modules 14 .
  • the bulkhead door 36 is chamfered in the front region 37, as a result of which it can be gently pushed between the propellant charge modules 14 and limit the propellant charge modules 14 to be accommodated for the portioner 10.
  • the propellant charge shell 20 is also U-shaped and lies with its open longitudinal side 21 directly opposite the open longitudinal side 32 of the portioner 10.
  • the closed rear side of the propellant charge shell 20 is connected via a web 25 to a bearing 43 arranged on the transfer arm 42 and can thereby be pivoted upward in the direction 45 about the transfer arm 42.
  • the transfer arm 42 which can be rotated about the shield pin axis 44, picks up the propellant charge modules 14 in the shortest possible loading time via the charging cradle 20 from the portioner 10 and then pivots them, opposite the direction 46, behind the weapon barrel for direct delivery into a weapon barrel cargo space, not shown.
  • two sliders 22 which can be driven in parallel in the manner described above are arranged on the portioner 12 and are connected on the inside of the portioner 12 via a single slide surface 33 corresponding to the length of the portioner 12.
  • the propellant charge modules 14 of the portioner 12 which are quantitatively predetermined in this case by a bulkhead door that can be moved in the vertical direction 47, are likewise briefly supplied to the charging cradle 20 via the slide surfaces 33.
