Definitions

  • the invention relates to a method and a device for supplying ammunition to revolver cannons, wherein a first conveying member takes cartridges from an external magazine and transports them to a second conveying member, which transfers the cartridges to a loading star firmly connected to a drum of the revolver cannon, during its rotation the cartridges in Cartridge bearings of the drum are inserted, and the rotation of the drum generated by the explosion pressure during the firing operation is transmitted to the first and second conveying members via a coupling.
  • revolver drum heated during firing is generally cooled by the ambient air .
  • the invention has for its object to improve a method and an apparatus of the type mentioned in such a way that, in order to avoid the disadvantages mentioned above, there is no ammunition in the drum if the drum temperature is too high.
  • a switch is set when the certain temperature is exceeded, so that the cartridges located in the external magazine are transported past the first conveying member and remain in the magazine.
  • the cartridges on the first and second conveying members and in the drum are then fired and, after the drum has come to a standstill, the clutch is opened so that the drum is uncoupled from the conveying members. Then the cartridges of the external magazine transported past the first conveying element are conveyed back again.
  • the switch is then reset and cartridges are transported to the first and second conveyor links.
  • the clutch is engaged again.
  • the drum and the first and second conveying members are rotated by the separate through-loading device, the drum being loaded and the separate through-loading device being switched off again when the first cartridge has reached the ignition position and the firing burst begins.
  • the advantages achieved by the invention are, in particular, that the proposed solutions are less expensive than, for example, a cooling device that works with cooling liquid.
  • the impairment of the cannon functions and strength problems are avoided and the tension curve in the drum is improved. Further advantages can be seen in the low manufacturing costs as well as in the small change effort for existing cannons.
  • auto-ignition is avoided, which increases safety. Since there are no cartridges in the drum after firing, safety during maintenance is also guaranteed.
  • 1 , 1 denotes an external magazine, which has a rotating conveyor chain 3 arranged in a housing 2 .
  • Cups 4 are provided on the conveyor chain 3 , in which cartridges 5 are held during transport to a drum 6 of a revolver cannon.
  • star-shaped deflection wheels 8 and star-shaped transfer wheels 9 are arranged on a common rotatable axis 7 , the deflection wheels 8 being in engagement with the conveyor chain 3 .
  • a first conveyor link 10 provided in the area of the deflection wheels 8 takes cartridges 5 from the conveyor chain 3 or the transfer wheels 9 , the cartridges 5 being transported along a circular guide surface 11 away from the transfer wheels 8 onto a second conveyor link 12 .
  • the first conveyor member 10 consists of two three-pointed stars arranged on a common rotatable axis 13 , the gaps of which are adapted to the cross-sectional shape of the cartridges 5 .
  • the second conveyor member 12 is also rotatably arranged and has a guide surface for receiving a cartridge 5 in each case. 14 with a coaxial to the drum, attached to this loading star is designated, to which the second conveyor member 12 transfers the cartridges 5 .
  • a scanning device 15 arranged above a cartridge 5 located on the second conveying member 12 controls the position of the first cartridge 5 .
  • 20 denotes a switch known from European patent specification 0 184 008 , which has two deflection segments 21 , 22 and which is arranged between the deflection wheels 8 and the first conveying member 10 .
  • the deflecting segments 21 , 22 can be displaced relative to one another in the longitudinal direction of the cartridges 5 , so that either the cartridges 5 are transferred to the first conveying element 10 when the first deflecting segment 21 is effective or remain on the conveyor chain 3 when the second deflecting segment 22 is effective.
  • the switch 20 can be actuated as a function of temperature, for which purpose a temperature sensor for measuring the drum temperature is provided, which is electrically connected, for example via an amplifier, to an actuator acting on the deflection segments 21 , 22 .
  • a clutch 30 arranged coaxially with the loading star 14 can be switched into three positions.
  • the clutch 30 consists of a first clutch disk 31 , which is non-rotatably connected to the loading star 14 and is axially displaceable, and a second, axially non-displaceable clutch disk 32 provided with teeth.
  • a first position FIG. 3a
  • the first and second clutch disks 31 , 32 are in engagement with one another, the rotary movement of the drum 6 or the loading star 14 being transmitted to the first and second conveying members 10 , 12 via gearwheels 33 , 34 and 35 becomes.
  • a second position FIG.
  • the first and second clutch disks 31 , 32 are not in engagement, so that no movement transmission takes place between the loading star 14 and the conveying members 10 , 12 .
  • the second clutch disc 32 is engaged with a shift lever 36 , so that the conveyor members 10 , 12 are blocked and z. B. cartridges 5 can be safely removed from the drum 6 .
  • the temperature sensor for measuring the drum temperature notifies the control system when the critical temperature is exceeded that the burst of fire must be interrupted by actuating the clutch.
  • the clutch 30 can be actuated as a function of temperature, for which purpose a temperature sensor for measuring the drum temperature is provided, which is electrically connected, for example via an amplifier, to an actuator acting on the shift lever 36 .
  • the device described above according to the first and second embodiment works as follows: When a first cartridge 5 from the external magazine 1 reaches the second conveying member 12 during a loading process (clutch in position FIG. 3b ), a signal from the scanning device 15 is triggered. Then a separate through-loading device (not further described) is switched on and, with the coupling 30 of the loading star 14 and the conveying members 10 , 12 in the first position ( FIG. 3a ), set in rotation ( FIG. 4a ). In this case, the cartridge 5 located on the second conveying member 12 is transferred to the loading star 14 and then pushed into a cartridge chamber of the drum 6 by means of a cartridge pusher (not shown).
  • the device is designed such that three cartridges 5 are transferred to the loading star 14 and inserted into the cartridges of the drum 6 , the first cartridge 5 reaching an ignition position 16 . ( Fig. 4b ).
  • the cartridges 5 are now ignited one after the other, the drum 6 , the Loading star 14 and the two conveying members 10 , 12 driven by the explosion pressure and further cartridges 5 are conveyed from the external magazine 1 .
  • the clutch 30 When a certain temperature of the drum 6 is exceeded, according to the first embodiment of the device, the clutch 30 is switched to the position in FIG. 3c , so that the first and second conveying members 10 , 12 are decoupled and blocked from the loading star 14 and no more cartridges 5 are transferred to it are ( Fig. 4c ). After the cartridges 5 in the drum have been fired, the drum 6 stands still ( FIG. 4d ). In the following burst of fire, the clutch 30 is switched back to the first position and, as already described with reference to FIGS. 4a and 4b, a new charging process is carried out. When the first cartridge 5 has reached the ignition position, the burst of fire begins.
  • the device according to the second embodiment works in the same way as the device according to the first embodiment during a charging process and the subsequent shooting.
  • the switch 20 is adjusted, so that cartridges 5 located in the external magazine 1 are transported past the first conveyor link 10 along the second deflection segment 22 and remain on the conveyor chain 3 ( FIGS. 5a, 5b ).
  • the cartridges 5 located on the first and second conveyor members 10 , 12 and in the drum 6 are fired, whereupon the drum stands still ( FIG. 5b ).
  • the clutch 30 is then switched to the second position, so that the drum 6 or the loading star 14 is uncoupled from the first and second conveying members 10 , 12 .
  • the first embodiment can be used with long conveyor chains 3 , the chain links of which have sufficient play.
  • the conveyor chain 3 can be moved even further if the deflection wheels 8 are blocked until the drum 6 is empty.
