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 a second conveyor, for transporting the cartridges pushed out of the sectors to the firearm, with means for rotating the drum magazine in a certain direction, each sector of the drum magazine reaching a removal position, while the drum magazine rotates in the mentioned direction, each cartridge row pushed out in a first given direction from the sector in the removal position, the first conveyor is arranged obliquely, this oblique position results as a result of the given direction of rotation of the drum magazine and the given direction in which the cartridges from the sector be pushed out with a backstop between the two conveyors to prevent cartridges from falling into the already empty sectors.
  • the backstop is formed by a slide which has a passage opening for the cartridges ejected from the sectors of the drum magazine and a deflection nose through which the cartridges are placed in individual receptacles of a conveyor chain second conveyor are steered.
  • the backstop is formed by pivotable flaps which are articulated at the ejection end of the guide rails of the drum magazine and which open when the cartridges are ejected, but prevent the cartridges from falling back into the sectors of the drum magazine.
  • This known device both the first and the second exemplary embodiment, has the disadvantage that it does not work sufficiently reliably with a high cadence of the firearm, as a result of which interference of all kinds arise.
  • the object which is to be achieved with the present invention is to create a device with which the cartridges are reliably transferred from the first conveying device to the second conveying device, in particular when the transition from one sector to the next sector is not allowed to occur, ie as soon as the last cartridge of one sector has been transferred to the second conveyor, the first cartridge of the next sector should be fed to the second conveyor without interruption.
  • the backstop has two pivotable flaps which are connected to one another and which together form a funnel-shaped, pivotable channel through which the cartridges are pushed through the first conveying device to the second conveying device.
  • the drum magazine 10 consists of an inner container 11 and an outer container 12.
  • first type of ammunition 13 In the inner container 11 there is a first type of ammunition 13 and in the outer container 12 there is a second type of ammunition 14. Both containers 11 and 12 are divided into a number of sectors and, according to Fig. 2, five cartridges are contained in each sector.
  • first conveying device 15 In the inner container 11 there is a first conveying device 15 and in the outer container 12 there is another first conveying device 16.
  • These two first conveying devices which are also referred to as removal device 15, 16 or as skewed skew, look the same. The expression “skewed skew" can be understood from FIG. 2 and the following description. Only one of the first two conveying devices is explained below.
  • the first conveyor 16 has two rollers 17 and 18, over which an endless belt 19 is guided.
  • two rollers 17, 17a and 18, 18a can be provided according to FIG. 3, and instead of a single wide conveyor belt 19, two narrow conveyor belts 19 and 19a can be provided.
  • Two carriers 20 and 21 are fastened to these belts 19 and 19a.
  • the endless belt 19 with the two drivers 20 and 21 moves in the direction of arrow A, the upper driver 21 pushing a cartridge 22 of a sector out of the drum magazine 10.
  • the other driver 20 will then bump against the bottom cartridge 23 of the next sector and thereby push the top cartridge 24 of the next sector out of the drum magazine. 1, the entire drum magazine 10 rotates clockwise, ie in the direction of arrow B in FIG.
  • the endless conveyor belt 25a moves from roll 26 to roll 27 between the two rolls 26 and 27. It therefore does not matter in the known device that, as mentioned, the cartridge 22 plays out at a different location the container 12 of the conveyor 25 is transferred as the cartridge 24, which is transferred to the conveyor belt 25a further to the right according to FIG.
  • the cartridges from the inner container 11 are transferred to a second conveyor belt 28 of the second conveyor device 25, which moves in the direction of the arrows D, the other first conveyor device 15 receiving the cartridges from the inner one Pushes out container 11.
  • the second conveyor belt 28 is also guided over rollers, not shown, which are arranged essentially coaxially with the rollers 26 and 27, but rotate in the opposite direction.
  • a motor 37 drives a shaft 39 via three gear wheels 38.
  • the rollers 31, 31a which are shown here as sprockets, are fastened and, on the other hand, a gear 40, which drives the first conveyor device 15 or 16 via gear wheels 41.
  • the gear wheels 41 drive a shaft 42 on which the rollers 18 and 18a are attached.
  • a worm 43 is also fastened, which drive the inner container 11 or the outer container 12 via a gear 44, of which only an inner ring gear 45 is indicated in FIG. It can be seen from the arrows B that the two containers 11 and 12 rotate in the opposite direction.
  • FIG. 4 only the upper part of the first conveyor device 15 and 16 is shown, namely the upper roller 18, 18a, the endless conveyor belt 19, 19a and the one carrier 21.
  • the carrier 22 is removed from the drum magazine 10 by this carrier 21 pushed out.
  • an upper wall is indicated in FIG. 4, which has an opening 29 which is just large enough to expel the last cartridge 22 of one sector on the right and then the first cartridge 24 of the next sector on the left can be.
  • the endless conveyor chain 30 is guided and moved over a single roller or star wheel 31 in the direction of the arrows D. Both the cartridge and the cartridge 24 are shown in Fig.
  • a cam disk 36 is used to pivot the two flaps 32 and 33, which pivots the flap 33 from the first into the second position, shown with dashed lines.
  • the other flap 32 is also pivoted via a rod 46.
  • the opening 29 is stationary.
  • the cam disk 36 is also indicated in FIG. 3 and is located there on shaft 39, while in the simplified schematic illustration according to FIG. 4 it is located further down on the right.
  • the operation of the cartridge feeder described is as follows: In the case of a series fire, one of the two electric motors 37 (FIG. 3) is switched on in accordance with the desired ammunition type, as a result of which the shaft 39 is driven via the gear wheels 38 and the shaft 42 is driven via the gear wheels 40 and 41.
  • the shafts 39 and 42 drive the two conveying devices 30 and 15, 16 according to FIG. 4.
  • the first conveyor device 15 first moves the last cartridge 22 of a sector of the drum magazine 10 step by step into the position 22 1, 222 223, the upper driver 21 being effective.
  • the first conveyor device then moves the first cartridge 24 of the next sector of the drum magazine 10 step by step into the positions 24 1, 24 2 and 24 3, the lower driver 20 (FIG. 3) being effective.
  • each individual flap 32 and 33 can be driven by a separate cam plate 36.
  • one flap 33 can be replaced by two flaps 33 and 33a arranged one behind the other, which are mounted on a common axis 34, one flap 33 supporting the rear end of a cartridge 22, 24 and the other flap 33a supports the front end of the same cartridge 22, 24.
  • the opposite flap 32 supports the middle part of the cartridge 22, 24. Since the cartridges 22, 24 in the drum magazine 10 move in a circle (see FIG.
