Definitions

  • the invention relates to a conveyor device for feeding cartridges to a firearm from a drum magazine, which is divided into a number of sectors, in each of which there is a row of cartridges, with a first conveyor device which pushes the rows of cartridges out of the sectors of the drum magazine and with one second conveyor for transporting the cartridges pushed out of the sectors to the firearm.
  • the first conveyor device consists of an encircling, endless chain provided with drivers, which is in drive connection with the rotating drum magazine. From this first conveying device, the cartridges pass into a second conveying device, which is in drive connection with it, and consists of a conveyor disk, which in turn conveys the cartridges into the weapon.
  • the object that is to be achieved with the present invention is to create a conveyor device which ensures reliable transport of the cartridges from the drum magazine to the firearm even at high cadences.
  • the transfer of the cartridges from the first conveyor to the second conveyor should function reliably without cartridges falling into the already empty sectors of the drum magazine.
  • no great acceleration forces should occur when a row of cartridges is pushed out of a sector.
  • no great acceleration forces should occur when the cartridges are transferred from the first conveyor to the second conveyor.
  • the device with which this object is achieved is characterized in that a backstop is arranged between the two conveying devices and that the first conveying device has a screw conveyor, the first turn of which has a smaller pitch than the other turns.
  • the cartridges 11 are fed from a drum magazine 10 via a conveyor channel 12 to a firearm 13.
  • the firearm 13 is shown in Fig.l in three different elevation positions. In the middle position, the gun barrels 14 of the firearm 13 are directed horizontally. From this position, the weapon 13 can be lowered on the one hand until the weapon barrels are inclined downward by approximately 10-15 °, and on the other hand the weapon can be raised by approximately 90 ° until the weapon barrels 14 project approximately into the zenith.
  • the downwardly inclined weapon barrels 14 are designated by the reference number 14a and the weapon barrels 14 projecting into the zenith are designated by the reference number 14b.
  • FIG. 2 there is a so-called disk channel 15 between the delivery channel 12 and the weapon 13, which allows an elevation of the firearm 13 by approximately 90 °.
  • the cartridges 11 pass from the drum magazine 10 onto an endless conveyor chain 16.

While a row of cartridges 19 is pushed out of the drum magazine 10, this rotates Drum magazine 10 continuously by one division, ie position A of drum magazine 10 comes to position B.
  • drum magazine 10 rotates a division, whereby the cartridge 11 moves from point A to point B.
  • the cartridges 11 ejected from the drum magazine 10 pass through the conveyor channel 12, which is indicated in FIG. 4 by two walls 28, 29, to the firearm 13.
  • this conveyor channel 12 there is a second conveyor device 30a, which is described further below.
  • the direction of movement of the cartridges 11 resulting from the rotation of the drum magazine 10 in the direction of the arrow D and the axial displacement of the cartridge row 19 coincides with the conveying direction of the conveyor device 27, ie the axis of this conveyor device 27 is inclined so that its direction matches this resulting direction of movement coincides, as can be clearly seen from FIG.
  • a backstop in front of the opening 26 described further below prevents the cartridges 11 ejected from the drum magazine 10 by the conveying device 27 from falling back through the opening 26.
  • the conveyor device 27 has a screw conveyor 30.
  • the screw conveyor 30 consists of a cylindrical body 31 to which a helical rib 32 is attached.
  • the two ends of the screw conveyor 30 are held in bearings 33 (FIG. 5) and 34 (FIG. 6) in the housing 24 of the drum magazine 10.
  • To drive the screw conveyor 30 is a gear 35, which is attached to one end of the screw conveyor 30.
  • the gear 35 is driven by a hydraulic motor, as described below.
  • the drum magazine 10 contains a drum axis 21.
  • the two ends of the drum axis 21 are held in bearings 36 (Fig.5) and 37 (Fig.6) in the housing 24 of the drum magazine 10.
  • a gear 38 which is attached to an end face of the drum magazine 10 and is driven by the aforementioned electric motor, as described below.
  • Each row of cartridges 19, 20 is held in the drum magazine 10 so as to be displaceable in an axially directed rail 39.
  • the first cartridge 11 of such a cartridge row 19 is shown in FIG. 5 and the last cartridge 11 in FIG.
  • a driver 40 is displaceable, which has a bolt 41.
  • the bolt 41 is in engagement with the helical rib 32 of the screw conveyor 30.
