Definitions

  • the invention relates to a monitoring device for late detonators for an externally powered gun, with an ammunition feed housing, in which a switch is slidably mounted, which, in the event of a delay in ignition, redirects the cartridges supplied to the weapon into an ejection channel and these remain on an endless chain.
  • the cartridges are transported into the weapon housing by means of a star wheel and are pushed there into one or more gun barrels by one or more locks. After the cartridges have been fired, the empty cases are pulled out of the barrel and ejected. If the ignition is delayed, the cartridge is no longer pulled out of the barrel and no more cartridges may be added. The cartridges fed through the star wheel are therefore no longer fed to the weapon, but instead are returned on an endless chain. For this purpose, a switch is switched in the event of an ignition delay, so that the cartridges are no longer transported to the weapon, but remain on the endless chain.
  • the object that is to be achieved with the present invention is to provide a monitoring device with a switch which carries out a relatively small stroke and has a relatively small mass and thus requires small switching forces so that the var wear is small and reliable switching is guaranteed.
  • the monitoring device with which this object is achieved is characterized in that the switch consists of two segments which can be displaced in the direction of the cartridge axes, one of which optionally projects into the path of the cartridges.
  • the two segments are preferably articulated at the ends of a balance beam which is pivotally mounted in a housing in order to inevitably move the two segments in the opposite direction.
  • there is at least one compression spring which is supported on the one hand on a segment and on the other hand on the housing and has the endeavor to shift one segment into the active position and the other segment into its inactive position.
  • An actuating cable is preferably attached to a segment in order to actuate the segments in order to push this segment into its inactive position against the force of the compression spring.
  • guide pins which protrude into bores of the segments are fastened in the housing for guiding the segments, the segments being displaceable on these pins.
  • the device for feeding the ammunition to the firearm 10 has a housing 15 in which three star wheels 16, 17 and 18 are rotatably mounted. These three star wheels 16, 17, 18 are driven by a gear transmission (not shown).
  • the first star wheel 16, also called the feed wheel has five receiving points for the cartridges.
  • the second star wheel 17, also referred to as a transfer wheel has only four pick-up points for the cartridges 13 to be fed to the weapon 10.
  • the third star wheel 18, also referred to as an ejection wheel has four pick-up points for the empty cartridge cases 14.
  • the housing 15 mentioned has three openings, namely an inlet opening 19 through which the ammunition to be fired, ie the cartridges 13 are fed, and a first outlet opening 20 through which there may not be closed, but still sharp cartridges remain on an endless belt, not shown, and a second outlet opening 21 through which the empty cartridge cases 14 are ejected.
  • the cartridges 13 are fed into the inlet opening 19 in a manner known per se, by means of an endless conveyor belt (not shown) or another transport means known per se.
  • the cartridges 13 located in the inlet opening 19 are gripped by the receiving points or shells 22 of the feed wheel 16 and transported to the point E. At this point E, the cartridge 13 is not only in the receiving shell 22 of the feeder wheel 16, but also already in a receiving shell 23 of the transfer wheel 17.
  • the cartridge 13 can either through the transfer wheel 17 to the point A of the cannon 10 be supplied, or be moved back through the feed wheel 16 to the outlet opening 20, as indicated by the two arrows 24 and 25.
  • two movable segments 26 and 27 are provided in order to be able to either feed the cartridge 13 in the direction of the arrow 24 of the weapon 10 or to be able to return it to the ammunition container in the direction of the arrow 25, two movable segments 26 and 27 are provided. These two segments 26 and 27 can be moved from an active position to an inactive position. If one segment 27 is in its active position, the cartridges 13 reach the weapon 10 and if the other segment 26 is in its active position, the cartridges remain on the endless belt and can then be returned to the magazine.
  • the two segments 26 and 27 are slidably arranged in a housing 28.
  • four pins 30 are fastened in the housing base 29, which protrude into corresponding bores in the segments 26 and 27.
  • a pin 31 is fastened, which projects into a corresponding hole in two balance beams 32.
  • the two balance beams 32 are pivotally mounted about bolts 33 in the housing 28 and have the task of lowering the other segment when lifting one segment.
  • Two plate spring assemblies 34 endeavor to push the segment 26 out of its lowest position shown (FIG. 3) into its uppermost position.
  • a cable 35 which is fastened to segment 26 with the aid of a screw 36, can pull segment 26 against the force of plate spring assemblies 34 into the lowest position shown. 3 and 4, the cable 35 is tensioned and the plate spring assemblies 34 are compressed.
  • the segment 26 is in its lowest, inactive position and the segment 27 in its active position at the top. In this initial position, the cartridges 13 thus reach the cannon 10.
  • two star wheels 16 and two star wheels 17 are fastened to a shaft 40 and 44, respectively, which are located in the housing 15 (FIG. 1) between two walls 37 and 38 and via four ball bearings 39 in these walls 37 and 38 are stored.
  • the cartridge 13 located at position E according to FIG. 1 is held according to FIG. 5 except by the four star wheels 16 and 17 and by one of the segments 26 or 27 by a disk 41 which engages in the extraction groove 42 of the cartridge 13 . This is necessary so that the cartridge 13 cannot tip over in the direction of the arrow 43 as soon as it is only held by one of the two star wheels 16 or 17 during its transport from the point E in the direction of one of the arrows 24 and 25.
  • the cartridges 13 When initiating a series fire, the cartridges 13 are transported by a conveyor device, not shown, from an ammunition container to the inlet opening 19 (FIG. 1) and brought to the point E by the feed wheel 16. Since the two segments 26 and 27 are in the starting position shown in FIG. 3, the cartridges 13 are then brought to position A (FIG. 1) by the transfer wheel 17 (arrow 24). From here, the cartridges 13 are inserted into a weapon barrel 11 through a breech, not shown, and the breech is then locked. At point B (Fig. 1), the cartridge 13 is ignited. At point C (FIG. 1), the empty cartridge case is pulled out of weapon barrel 11 and arrives at point D (FIG. 1), where it is gripped by ejector wheel 18 and ejected through second outlet opening 21.
